Michigan State University study: Healthcare providers — not hackers — leak more of your data

22 Nov

Lucas Mearian reported in Hackers are coming for your healthcare records — here’s why:

Data stolen from a bank quickly becomes useless once the breach is discovered and passcodes are changed. But data from the healthcare industry, which includes both personal identities and medical histories, can live a lifetime.
Cyberattacks will cost hospitals more than $305 billion over the next five years and one in 13 patients will have their data compromised by a hack, according to industry consultancy Accenture….
The Brookings research demonstrates that the healthcare sector is uniquely vulnerable to privacy breaches. For one thing, government regulations forced healthcare operations to adopt electronic health records (EHR) and other advances under the Patient Protection and Affordable Care Act (Obamacare) even if they weren’t ready to adequately invest in security.
Healthcare records also contain the most valuable information available, including Social Security numbers, home addresses and patient health histories — making them more valuable to hackers than other types of data, according to the study by the Brookings Institution’s Center for Technology Innovation. Since cybercriminals can sell data for a premium on the black market, hackers have a big incentive to focus their attacks on the healthcare industry.
With the push toward more integrated care, “medical data are now being shared with many different types of entities in which many employees have access to patient records,” the study said. “Extended access to medical records increases the potential for privacy breaches.”
To comply with legal requirements, healthcare organizations often store detailed medical information for many years. The probability of a breach — and the potential severity of the consequences — increases according to the amount of data stored and the length of time it is stored….
The greatest threat to the healthcare industry today, Safavi said, is not from one-off hackers seeking quick paydays, but from foreign governments that can store intimate personal health data for future use against individuals.
For example, hackers last year stole the records of about 80 million customers of Anthem Inc., the second largest U.S. health insurer.
“The presumption was that they were state actors,” Safavi said. “The purpose of the state actor was to harvest the database in order to create a dossier of individuals that they could use for social engineering for future attacks….” https://www.computerworld.com/article/3090566/healthcare-it/hackers-are-coming-for-your-healthcare-records-heres-why.html

A Michigan State University study highlighted the risks of inadequate security by medical providers against hackers.

Science Daily reported in Healthcare providers — not hackers — leak more of your data:

Your personal identity may fall at the mercy of sophisticated hackers on many websites, but when it comes to health data breaches, hospitals, doctors offices and even insurance companies are oftentimes the culprits.
New research from Michigan State University and Johns Hopkins University found that more than half of the recent personal health information, or PHI, data breaches were because of internal issues with medical providers — not because of hackers or external parties.
“There’s no perfect way to store information, but more than half of the cases we reviewed were not triggered by external factors — but rather by internal negligence,” said John (Xuefeng) Jiang, lead author and associate professor of accounting and information systems at MSU’s Eli Broad College of Business.
The research, published in JAMA Internal Medicine, follows the joint 2017 study that showed the magnitude of hospital data breaches in the United States. The research revealed nearly 1,800 occurrences of large data breaches in patient information over a seven years, with 33 hospitals experiencing more than one substantial breach.
For this paper, Jiang and co-author Ge Bai, associate professor at the John’s Hopkins Carey Business School, dove deeper to identify triggers of the PHI data breaches. They reviewed nearly 1,150 cases between October 2009 and December 2017 that affected more than 164 million patients.
“Every time a hospital has some sort of a data breach, they need to report it to the Department of Health and Human Services and classify what they believe is the cause,” Jiang, the Plante Moran Faculty Fellow, said. “These causes fell into six categories: theft, unauthorized access, hacking or an IT incident, loss, improper disposal or ‘other.'”
After reviewing detailed reports, assessing notes and reclassifying cases with specific benchmarks, Jiang and Bai found that 53 percent were the result of internal factors in healthcare entities.
“One quarter of all the cases were caused by unauthorized access or disclosure — more than twice the amount that were caused by external hackers,” Jiang said. “This could be an employee taking PHI home or forwarding to a personal account or device, accessing data without authorization, or even through email mistakes, like sending to the wrong recipients, copying instead of blind copying or sharing unencrypted content.”
While some of the errors seem to be common sense, Jiang said that the big mistakes can lead to even bigger accidents and that seemingly innocuous errors can compromise patients’ personal data….” https://www.sciencedaily.com/releases/2018/11/181120073655.htm

HEALTH CARE PROVIDERS – NOT HACKERS – LEAK MORE OF YOUR DATA

Your personal identity may fall at the mercy of sophisticated hackers on many websites, but when it comes to health data breaches, hospitals, doctors offices and even insurance companies are oftentimes the culprits.
New research from Michigan State University and Johns Hopkins University found that more than half of the recent personal health information, or PHI, data breaches were because of internal issues with medical providers – not because of hackers or external parties.
“There’s no perfect way to store information, but more than half of the cases we reviewed were not triggered by external factors – but rather by internal negligence,” said John (Xuefeng) Jiang, lead author and associate professor of accounting and information systems at MSU’s Eli Broad College of Business.

“Every time a hospital has some sort of a data breach, they need to report it to the Department of Health and Human Services and classify what they believe is the cause,” Jiang, the Plante Moran Faculty Fellow, said. “These causes fell into six categories: theft, unauthorized access, hacking or an IT incident, loss, improper disposal or ‘other.’”
After reviewing detailed reports, assessing notes and reclassifying cases with specific benchmarks, Jiang and Bai found that 53 percent were the result of internal factors in health care entities.
“One quarter of all the cases were caused by unauthorized access or disclosure – more than twice the amount that were caused by external hackers,” Jiang said. “This could be an employee taking PHI home or forwarding to a personal account or device, accessing data without authorization, or even through email mistakes, like sending to the wrong recipients, copying instead of blind copying or sharing unencrypted content.”
While some of the errors seem to be common sense, Jiang said that the big mistakes can lead to even bigger accidents and that seemingly innocuous errors can compromise patients’ personal data.
“Hospitals, doctors offices, insurance companies, small physician offices and even pharmacies are making these kinds of errors and putting patients at risk,” Jiang said.
Of the external breaches, theft accounted for 33 percent with hacking credited for just 12 percent.
Some data breaches might result in minor consequences, such as obtaining the phone numbers of patients, but others can have much more invasive effects. For example, when Anthem, Inc. suffered a data breach in 2015, 37.5 million records were compromised. Many of the victims were not notified immediately, so weren’t aware of the situation until they went to file their taxes only to discover that a third-party fraudulently filed them with the data they obtained from Anthem.
While tight software and hardware security can protect from theft and hackers, Jiang and Bai suggest health care providers adopt internal policies and procedures that can tighten processes and prevent internal parties from leaking PHI by following a set of simple protocols. The procedures to mitigate PHI breaches related to storage include transitioning from paper to digital medical records, safe storage, moving to non-mobile policies for patient-protected information and implementing encryption. Procedures related to PHI communication include mandatory verification of mailing recipients, following a “copy vs. blind copy” protocol (bcc vs cc) as well as encryption of content.
“Not putting on the whole armor opened health care entities to enemy’s attacks,” Bai said. “The good news is that the armor is not hard to put on if simple protocols are followed.”
Next, Jiang and Bai plan to look even more closely at the kind of data that is hacked from external sources to learn what exactly digital thieves hope to steal from patient data. https://msutoday.msu.edu/news/2018/health-care-providers-not-hackers-leak-more-of-your-data/

Protecting vital information from hackers of all types is constantly chasing a moving target.

Medical providers range from small offices to large institutions and university departments. Wendy Zamora wrote in 10 ways to protect against hackers:

What can you do to protect it against cybercriminals? Instead of sitting back and waiting to get infected, why not arm yourself and fight back?
Bad guys, beware. We’ve got 10 ways to beat you.
1. Update your OS and other software frequently, if not automatically. This keeps hackers from accessing your computer through vulnerabilities in outdated programs (which can be exploited by malware). For extra protection, enable Microsoft product updates so that the Office Suite will be updated at the same time. Consider retiring particularly susceptible software such as Java or Flash, especially as many sites and services continue to move away from them.
2. Download up-to-date security programs, including anti-malware software with multiple technologies for protecting against spyware, ransomware, and exploits, as well as a firewall, if your OS didn’t come pre-packaged with it. (You’ll want to check if your OS has both firewall and antivirus built in and enabled by default, and whether those programs are compatible with additional cybersecurity software.)
3. Destroy all traces of your personal info on hardware you plan on selling. Consider using d-ban to erase your hard drive. For those looking to pillage your recycled devices, this makes information much more difficult to recover. If the information you’d like to protect is critical enough, removing the platters where the information is stored then destroying them is the way to go.
4. Do not use open Wi-Fi on your router; it makes it too easy for threat actors to steal your connection and download illegal files. Protect your Wi-Fi with an encrypted password, and consider refreshing your equipment every few years. Some routers have vulnerabilities that are never patched. Newer routers allow you to provide guests with segregated wireless access. Plus, they make frequent password changes easier.
5. Speaking of passwords: password protect all of your devices, including your desktop, laptop, phone, smartwatch, tablet, camera, lawnmower…you get the idea. The ubiquity of mobile devices makes them especially vulnerable. Lock your phone and make the timeout fairly short. Use fingerprint lock for the iPhone and passkey or swipe for Android. “It’s easy to forget that mobile devices are essentially small computers that just happen to fit in your pocket and can be used as a phone,” says Jean-Philippe Taggart, Senior Security Researcher at Malwarebytes. “Your mobile device contains a veritable treasure trove of personal information and, once unlocked, can lead to devastating consequences.”
6. Sensing a pattern here? Create difficult passwords, and never use the same ones across multiple services. If that’s as painful as a stake to a vampire’s heart, use a password manager like LastPass or 1Password. For extra hacker protection, ask about two-step authentication. Several services have only recently started to offer 2FA, and they require the user to initiate the process. Trust us, the extra friction is worth it. Two-factor authentication makes taking over an account that much more difficult, and on the flip side, much easier to reclaim should the worst happen.
7. Come up with creative answers for your security questions. People can now figure out your mother’s maiden name or where you graduated from high school with a simple Google search. Consider answering like a crazy person. If Bank of America asks, “What was the name of your first boyfriend/girlfriend?” reply, “Your mom.” Just don’t forget that’s how you answered when they ask you again.
8. Practice smart emailing. Phishing campaigns still exist, but cybercriminals have become much cleverer than that Nigerian prince who needs your money. Hover over links to see their actual URLs (as opposed to just seeing words in hyperlink text). Also, check to see if the email is really from the person or company claiming to have sent it. If you’re not sure, pay attention to awkward sentence construction and formatting. If something still seems fishy, do a quick search on the Internet for the subject line. Others may have been scammed and posted about it online.
9. Some websites will ask you to sign in with a specific service to access features or post a comment. Ensure the login option isn’t a sneaky phish, and if you’re giving permission to an app to perform a task, ensure you know how to revoke access once you no longer need it. Old, abandoned connections from service to service are an easy way to see your main account compromised by spam.
10. Keep sensitive data off the cloud. “No matter which way you cut it, data stored on the cloud doesn’t belong to you,” says Taggart. “There are very few cloud storage solutions that offer encryption for ‘data at rest.’ Use the cloud accordingly. If it’s important, don’t.”
Honorable mentions: Alarmist webpages announcing that there are “critical errors” on your computer are lies. Microsoft will never contact you in person to remove threats. These messages come from scammers, and if you allow them to remotely connect to your computer, they could try to steal your information and your money. If that’s not a Nightmare on Elm Street, then we don’t know what is. https://blog.malwarebytes.com/101/2015/10/10-ways-to-protect-against-hackers/

Hacking of medical records is cyber warfare and the best defense is a good offense.

American Geophysical Union study: Warmer winter temperatures linked to increased crime

18 Nov

Ohio State Researchers wrote about the impact of climate on crime in How does climate affect violence? Researchers offer new theory:

Researchers have long struggled to explain why some violent crime rates are higher near the equator than other parts of the world. Now, a team of researchers have developed a model that could help explain why.
This new model goes beyond the simple fact that hotter temperatures seem to be linked to more aggressive behavior.
The researchers believe that hot climates and less variation in seasonal temperatures leads to a faster life strategy, less focus on the future, and less self-control – all of which contribute to more aggression and violence….
Paul van Lange, lead author of the study and a professor of psychology at the Vrije Universiteit Amsterdam (VU) added, “We believe our model can help explain the impact of climate on rates of violence in different parts of the world….”

The CLASH model states that it is not just hotter temperatures that lead to more violence – it is also climates that have less seasonal variation in temperature.
“Less variation in temperature, combined with heat, brings some measure of consistency to daily life”, Rinderu said.
That means there is less need to plan for large swings between warm and cold weather. The result is a faster life strategy that isn’t as concerned about the future and leads to less need for self-control.
“Strong seasonal variation in temperature affects culture in powerful ways. Planning in agriculture, hoarding, or simply preparing for cold winters shapes the culture in many ways, often with people not even noticing it. But it does shape how much a culture values time and self-control,” Van Lange said.
“If there is less variation, you’re freer to do what you want now, because you’re not preparing foods or chopping firewood or making winter clothes to get you through the winter. You also may be more concerned with the immediate stress that comes along with parasites and other risks of hot climates, such as venomous animals.”
People living in these climates are oriented to the present rather than the future and have a fast life strategy – they do things now.
“We see evidence of a faster life strategy in hotter climates with less temperature variation – they are less strict about time, they have less use of birth control, they have children earlier and more often,” Bushman said.
With a faster life strategy and an orientation toward the present, people have to practice less self-control, he said. That can lead people to react more quickly with aggression and sometimes violence.
The theory is not deterministic and isn’t meant to suggest that people in hotter, consistent climates can’t help themselves when it comes to violence and aggression…. https://news.osu.edu/how-does-climate-affect-violence-researchers-offer-new-theory/

The American Geophysical Union studied the link between temperature and crime.

Science Daily reported in Warmer winter temperatures linked to increased crime:

Milder winter weather increased regional crime rates in the United States over the past several decades, according to new research that suggests crime is related to temperature’s effect on daily activities.
A new study published in GeoHealth, a journal of the American Geophysical Union, finds U.S. crime rates are linked to warmer temperatures, and this relationship follows a seasonal pattern.
The findings support the theory that three major ingredients come together to bring about crime: a motivated offender, a suitable target, and the absence of a guardian to prevent a violation of the law. During certain seasons, namely winter, milder weather conditions increase the likelihood these three elements come together, and that violent and property crimes will take place, according to the new study. Unexpectedly, warmer summer temperatures were not linked with higher crime rates.
The new research abates existing theories that hot temperatures drive aggressive motivation and behavior, according to the study’s authors. Instead, the new research suggests crime is related to the way climate alters people’s daily activities.
“We were expecting to find a more consistent relationship between temperature and crime, but we weren’t really expecting that relationship to be changing over the course of the year,” said Ryan Harp, lead author of the study and a doctoral candidate in the Department of Atmospheric and Oceanic Sciences at the University of Colorado Boulder. “That ended up being a pretty big revelation for us.”
Understanding how climate affects crime rates could expand the boundaries of what scientists would consider to be a climate and health connection, Harp said.
“Ultimately, it’s a health impact,” he said. “The relationship between climate, human interaction, and crime that we’ve unveiled is something that will have an impact on people’s wellbeing.”
Regional climate affects human interaction
Previous studies have found a link between temperature and the incidence of crime, but none have looked at the relationship on a regional level and only some have controlled for underlying seasonal changes, allowing researchers to identify the potential underlying mechanism…. https://www.sciencedaily.com/releases/2018/11/181113110411.htm

WARMER WINTER TEMPERATURES LINKED TO INCREASED CRIME, STUDY FINDS
13 November 2018
WASHINGTON — Milder winter weather increased regional crime rates in the United States over the past several decades, according to new research that suggests crime is related to temperature’s effect on daily activities.
A new study published in GeoHealth, a journal of the American Geophysical Union, finds U.S. crime rates are linked to warmer temperatures, and this relationship follows a seasonal pattern.

Regional climate affects human interaction
Previous studies have found a link between temperature and the incidence of crime, but none have looked at the relationship on a regional level and only some have controlled for underlying seasonal changes, allowing researchers to identify the potential underlying mechanism.
In the new study, Harp and his co-author conducted a systematic investigation into the relationship between large-scale climate variability and regionally-aggregated crime rates, using a technique that allowed them to group together detailed spatial data on seasonal temperature and crime rates from across the United States.
They compared crime and climate data from the Federal Bureau of Investigation’s Uniform Crime Reporting (UCR) Program and the National Oceanic and Atmospheric Administration’s North American Regional Reanalysis (NARR). The data encompassed 16,000 cities across five defined US regions—Northeast, Southeast, South Central, West, and Midwest—from 1979 to 2016.
Their finding that violent crime is almost always more prevalent when temperatures are warmer in the winter months was especially notable in areas with the strongest winters, like the Midwest and Northeast, according to the researchers.
The new findings showing that increasing temperatures matter more in the winter than in the summer is interesting, said Marshall Burke, assistant professor of Earth System Science at Stanford University, who was not involved with the new study.
“The authors rightly suggest that this is more consistent with warmer temperatures altering people’s patterns of activity, like going outside more, than a physiological story about temperature and aggression,” he said.

There are various theories regarding why individuals commit crimes.

Steven Briggs wrote in Important Theories in Criminology: Why People Commit Crime:
Here is a broad overview of some key theories:

• Rational choice theory: People generally act in their self-interest and make decisions to commit crime after weighing the potential risks (including getting caught and punished) against the rewards.
• Social disorganization theory: A person’s physical and social environments are primarily responsible for the behavioral choices that person makes. In particular, a neighborhood that has fraying social structures is more likely to have high crime rates. Such a neighborhood may have poor schools, vacant and vandalized buildings, high unemployment, and a mix of commercial and residential property.
• Strain theory: Most people have similar aspirations, but they don’t all have the same opportunities or abilities. When people fail to achieve society’s expectations through approved means such as hard work and delayed gratification, they may attempt to achieve success through crime.
• Social learning theory: People develop motivation to commit crime and the skills to commit crime through the people they associate with.
• Social control theory: Most people would commit crime if not for the controls that society places on individuals through institutions such as schools, workplaces, churches, and families.
• Labeling theory: People in power decide what acts are crimes, and the act of labeling someone a criminal is what makes him a criminal. Once a person is labeled a criminal, society takes away his opportunities, which may ultimately lead to more criminal behavior.
• Biology, genetics, and evolution: Poor diet, mental illness, bad brain chemistry, and even evolutionary rewards for aggressive criminal conduct have been proposed as explanations for crime. https://www.dummies.com/education/psychology/important-theories-in-criminology-why-people-commit-crime/
One crime reduction strategy is predictive policing.
The National Institute of Justice described predictive policing:
Overview of Predictive Policing
Law enforcement work is frequently reactive: Officers respond to calls for service, quell disturbances and make arrests. Today more than ever, law enforcement work is also proactive.
In proactive policing, law enforcement uses data and analyzes patterns to understand the nature of a problem. Officers devise strategies and tactics to prevent or mitigate future harm. They evaluate results and revise practices to improve policing. Departments may combine an array of data with street intelligence and crime analysis to produce better assessments about what might happen next if they take various actions.
What Is Predictive Policing?
Predictive policing tries to harness the power of information, geospatial technologies and evidence-based intervention models to reduce crime and improve public safety. This two-pronged approach — applying advanced analytics to various data sets, in conjunction with intervention models — can move law enforcement from reacting to crimes into the realm of predicting what and where something is likely to happen and deploying resources accordingly.
The predictive policing approach does not replace traditional policing. Instead, it enhances existing approaches such as problem-oriented policing, community policing, intelligence-led policing and hot spot policing.
Predictive policing leverages computer models — such as those used in the business industry to anticipate how market conditions or industry trends will evolve over time — for law enforcement purposes, namely anticipating likely crime events and informing actions to prevent crime. Predictions can focus on variables such as places, people, groups or incidents. Demographic trends, parolee populations and economic conditions may all affect crime rates in particular areas. Using models supported by prior crime and environmental data to inform different kinds of interventions can help police reduce the number of crime incidents…. https://www.nij.gov/topics/law-enforcement/strategies/predictive-policing/Pages/welcome.aspx
Learn more about NIJ’s predictive policing and geospatial police strategies research. https://www.nij.gov/topics/law-enforcement/strategies/predictive-policing/Pages/research.aspx

Crime reduction strategy is based upon a variety of factors which affect the crime reduction strategy used in a particular locale.

Swansea University study: Excessive posting of selfies is associated with increase in narcissism

12 Nov

Lisa Firestone Ph.D. wrote in the Psychology Today article, Is Social Media to Blame For the Rise In Narcissism?

So who’s to blame for this generational increase in narcissism?
Can we pin the tail on Mark Zuckerberg and the advent of Facebook? Over the last couple years, a plethora of research has been pouring in that makes connections between Facebook and narcissism. Studies are consistently finding that people who score higher on the Narcissistic Personality Inventory questionnaire tend to have more friends on Facebook, tag themselves more often in photos and update their statuses more frequently. According to Laura Buffadi, a postdoctoral researcher at the Universidad de Dueto in Bilbao, Spain, “Narcissists use Facebook and other social networking sites because they believe others are interested in what they’re doing, and they want others to know what they are doing.”
In general, social media websites encourage self-promotion, as users generate all of the content. W. Keith Campbell explains that people often utilize Facebook “to look important, look special and to gain attention and status and self-esteem.” The trouble with this aspect of social networking is that nearly everyone presents an unrealistic portrait of themselves. Just as people select the most attractive photos of themselves to use as profile pictures, they tend to populate their newsfeeds with the most attractive bits of news about themselves. Of course, this is not always the case, but the unrealistically sunny picture that so many social networkers paint can have a negative psychological effect on their friends or followers. Recent studies of undergraduates across the country have shown that “students who were more involved with Facebook were more likely to think other people’s lives were happier and better.” These heavy Facebook users were also more likely to negatively compare themselves to others and feel worse about themselves.
While Facebook is certainly a platform for narcissists, it is a mistake to assume that Facebook alone has caused this spike in narcissism. As researcher Shawn Bergman pointed out, “There is a significant amount of psychological research that shows that one’s personality is fairly well-established by age 7,” given that Facebook’s policy doesn’t allow users to register until age 13 “the personality traits of typical users are fairly well-ingrained by the time they get on a social network.”
The truth is the rise in narcissism among millennials may have less to do with our social networks online and more to do with our social networks at home. Throughout the last few decades, there has been an increase in parental coddling and the so-called “self-esteem” movement. Parents and teachers trying to instill a healthy sense of self-esteem in children by praising them lavishly often do more harm than good. In fact, studies show that children offered compliments for a skill they have not mastered or talents that they do not have are left feeling emptier and more insecure. Only when children are praised for real accomplishments are they able to build actual self-esteem. https://www.psychologytoday.com/us/blog/compassion-matters/201211/is-social-media-blame-the-rise-in-narcissism

The question most want to ask about narcissists is, are they bad people?

Elinor Greenberg, Ph.D. wrote in the Psychology Today article, Are Narcissists Bad People? Do they choose to hurt other people or are they unable to control themselves?

Most of the hurt that narcissists cause is the result of two basic sets of issues:
1. The need to retaliate to protect their self-esteem
Blame and retaliation: During any sort of disagreement, or even a fairly neutral situation, as soon as narcissists start to feel bad, they are likely to see whomever they are with as responsible for their discomfort. They quickly move from blaming the other person to angrily retaliating.
Justification: They feel justified because without whole object relations or object constancy, they now see the other person as the all-bad enemy. In addition, they have temporarily lost touch with any positive past history between them and the other person.
Fragile self-esteem: Their fragile self-esteem makes it extremely painful for them to become aware of their part in causing a fight. They do not even try to see how they might be at fault because that would pierce their narcissistic defenses and result in them feeling imperfect and deeply shamed.
Difficulty apologizing: After they calm down, they may realize that they over-reacted and regret it. Unfortunately, their underlying shaky self-esteem makes it very unlikely they will admit they were wrong and apologize. Instead, they are likely to make a reparative gesture, such as giving the person a present.
However, if the other person wants to talk about what happened, they are likely to become very defensive and feel attacked. Then the cycle of blame and retaliation and reparation may start all over again.
2. Self-centeredness and lack of emotional empathy
Narcissists often unintentionally do things that hurt other people because they are so self-centered and lack emotional empathy. For example, they may make fun of you in front of other people and just think they are being funny. Or you may tell them that you have a stomach virus and instead of sympathizing, they tell you that they had one much worse than yours.
How do we judge them?
Do we give them a free pass to hurt other people because they have a narcissistic personality disorder? I would not. At the very least, most well-intentioned people with NPD:
• Know that they are selfish.
• Know that other people are getting hurt by them.
• Know psychotherapy exists and most are choosing not to go for help to change.
• Have been told that what they are doing is hurtful and continue doing it anyway.
But: This subset of narcissists are not setting out to hurt other people on purpose…. https://www.psychologytoday.com/us/blog/understanding-narcissism/201810/are-narcissists-bad-people

Researchers are studying the intersection of personality disorders and social media.

Science Daily reported in Excessive posting of selfies is associated with increase in narcissism:

A new study has established that excessive use of social media, in particular the posting of images and selfies, is associated with a subsequent increase in narcissism.
Published in The Open Psychology Journal, researchers from Swansea University and Milan University studied personality changes of 74 individuals aged 18 to 34 over a four-month period.
They also assessed the participants’ usage of social media — including Twitter, Facebook, Instagram and Snapchat — during that same period.
Narcissism is a personality characteristic that can involve grandiose exhibitionism, beliefs relating to entitlement, and exploiting others.

Here is the press release from Swansea University:

Excessive posting of photos on social media is associated with increase in narcissism
A new study has established that excessive use of social media, in particular the posting of images and selfies, is associated with a subsequent increase in narcissism.
Researchers from Swansea University and Milan University studied personality changes of 74 individuals aged 18 to 34 over a four-month period. They also assessed the participants’ usage of social media – including Twitter, Facebook, Instagram and Snapchat – during that same period.
The work was published in The Open Psychology Journal.
Narcissism is a personality characteristic that can involve grandiose exhibitionism, beliefs relating to entitlement, and exploiting others.
Those who used social media excessively, through visual postings, displayed an average 25% increase in such narcissistic traits over the four months of the study.
This increase took many of these participants above the clinical cut-off for Narcissistic Personality Disorder, according to the measurement scale used.

Professor Phil Reed from the Department of Psychology at Swansea University, who led the study, said:
“There have been suggestions of links between narcissism and the use of visual postings on social media, such as Facebook, but, until this study, it was not known if narcissists use this form of social media more, or whether using such platforms is associated with the subsequent growth in narcissism.
“The results of this study suggest that both occur, but show that posting selfies can increase narcissism.
“Taking our sample as representative of the population, which there is no reason to doubt, this means that about 20% of people may be at risk of developing such narcissistic traits associated with their excessive visual social media use.
“That the predominant usage of social media for the participants was visual, mainly through Facebook, suggests the growth of this personality problem could be seen increasingly more often, unless we recognise the dangers in this form of communication.”
Professor Roberto Truzoli from Milan University added:
“The use of visual social media may emphasise the perception of narcissistic individuals that they are the main focus of attention.
“The lack of immediate ‘direct’ social censure, may offer them the opportunity to inflict aspects of their narcissistic personality, present themselves in a grandiose manner, and realise fantasies of omnipotence.”

The healthy use of social media must be determined by each individual’

Pamela B. Rutledge Ph.D., M.B.A. wrote in the Psychology Today article, The Healthy Use of Social Media: Start with your goals. Is your social media use helping or hurting them?

Balance is key
While research does not support the fears about social media causing “addiction”, destroying empathy and social skills or turning a generation into narcissists, doing any one thing to the exclusion of others can create challenges. If you feel harrassed and overwhelmed by information overload or pressure from all that connectivity:
• Take the time to identify your larger goals, such as success at work or school, good relationships, or personal development.
• Evaluate your social media use and determine if it’s helping you meet those goals–keep a social media diary for a few days to learn what you use, when you use it and how it makes you feel
• Remember that you are the boss of your technology, not the other way around. Just because something rings or buzzes, doesn’t mean you have to answer
• Give youself permission to take a technology break from time to time and remind yourself what it feels like to be unplugged
• How you use your social media and mobile tools is unique to you and your goals. Don’t use others’ behavior to determine yours https://www.psychologytoday.com/intl/blog/positively-media/201310/the-healthy-use-social-media

While technology has advanced many aspects of civilization and made many tasks easier, its impact on social engagement and individual personality development may not be as salutatory.

“To know a species, look at its fears. To know yourself, look at your fears. Fear in itself is not important, but fear stands there and points you in the direction of things that are important. Don’t be afraid of your fears, they’re not there to scare you; they’re there to let you know that something is worth it.”

Stanford Medicine study: Older fathers associated with increased birth risks, study reports

8 Nov

Typically, older mothers are the subject of risk factor analysis for pregnancy after 35. The Mayo Clinic staff wrote in Pregnancy after 35: Healthy moms, healthy babies:

Understand the risks
The biological clock is a fact of life, but there’s nothing magical about age 35. It’s simply an age at which various risks become more discussion worthy. For example:
• It might take longer to get pregnant. You’re born with a limited number of eggs. As you reach your mid- to late 30s, your eggs decrease in quantity and quality. Also, older women’s eggs aren’t fertilized as easily as younger women’s eggs. If you are older than age 35 and haven’t been able to conceive for six months, consider asking your health care provider for advice.
• You’re more likely to have a multiple pregnancy. The chance of having twins increases with age due to hormonal changes that could cause the release of multiple eggs at the same time. The use of assisted reproductive technologies — such as in vitro fertilization — also can play a role.
• You’re more likely to develop gestational diabetes. This type of diabetes, which occurs only during pregnancy, is more common as women get older. Tight control of blood sugar through diet and physical activity is essential. Sometimes medication is needed, too. Left untreated, gestational diabetes can cause a baby to grow significantly larger than average — which increases the risk of injuries during delivery. Gestational diabetes can also increase the risk of premature birth, high blood pressure during pregnancy, and complications to your infant after delivery.
• You’re more likely to develop high blood pressure during pregnancy. Research suggests high blood pressure that develops during pregnancy is more common in older women. Your health care provider will carefully monitor your blood pressure and your baby’s growth and development. You will need more frequent obstetric appointments and you might need to deliver before your due date to avoid complications.
• You’re more likely to have a low birth weight baby and a premature birth. Premature babies, especially those born earliest, often have complicated medical problems.
• You might need a C-section. Older mothers have a higher risk of pregnancy-related complications that might lead to a C-section delivery. An example of a complication is a condition in which the placenta blocks the cervix (placenta previa).
• The risk of chromosome abnormalities is higher. Babies born to older mothers have a higher risk of certain chromosome problems, such as Down syndrome.
• The risk of pregnancy loss is higher. The risk of pregnancy loss — by miscarriage and stillbirth — increases as you get older, perhaps due to pre-existing medical conditions or fetal chromosomal abnormalities. Research suggests that the decrease in the quality of your eggs, combined with an increased risk of chronic medical conditions such as high blood pressure and diabetes, could increase your risk of miscarriage. Ask your health care provider about monitoring your baby’s well-being during the last weeks of pregnancy.
While further research is needed, studies suggest that men’s ages at the time of conception — the paternal age — also might pose health risks for children…. https://www.mayoclinic.org/healthy-lifestyle/getting-pregnant/in-depth/pregnancy/art-20045756

Stanford Medicine studied the risk factors associated with older fathers.

Science Daily reported in Older fathers associated with increased birth risks, study reports:

A decade of data documenting live births in the United States links babies of older fathers with a variety of increased risks at birth, including low birth weight and seizures, according to a new study by researchers at the Stanford University School of Medicine.
The data even suggest that the age of the father can sway the health of the mother during pregnancy, specifically her risk for developing diabetes.
“We tend to look at maternal factors in evaluating associated birth risks, but this study shows that having a healthy baby is a team sport, and the father’s age contributes to the baby’s health, too,” said Michael Eisenberg, MD, associate professor of urology.
Data from more than 40 million births showed that babies born to fathers of an “advanced paternal age,” which roughly equates to older than 35, were at a higher risk for adverse birth outcomes, such as low birth weight, seizures and need for ventilation immediately after birth. Generally speaking, the older a father’s age, the greater the risk. For example, men who were 45 or older were 14 percent more likely to have a child born prematurely, and men 50 or older were 28 percent more likely to have a child that required admission to the neonatal intensive care unit.
Still, these numbers aren’t reason to drastically change any life plans, as the risks are still relatively low, Eisenberg said. He compared the increased risks to buying lottery tickets. “If you buy two lottery tickets instead of one, your chances of winning double, so it’s increased by 100 percent,” he said. “But that’s a relative increase. Because your chance of winning the lottery started very small, it’s still unlikely that you’re going to win the lottery. This is a very extreme example, but the same concept can be applied to how you think about these birth risks.”
Instead, Eisenberg sees the findings as informational ammunition for people planning a family and hopes that they will serve to educate the public and health officials.
A paper describing the study will be published online Nov. 1 in the The British Medical Journal. Eisenberg is the senior author. Resident physician Yash Khandwala, MD, is the lead author…. https://www.sciencedaily.com/releases/2018/11/181101133759.htm

Older fathers associated with increased birth risks

From the data of more than 40 million births, scientists at Stanford have linked paternal age to birth risks, and even risks to the mother’s health.

A paper describing the study was published online Nov. 1 in the British Medical Journal. Eisenberg is the senior author. Resident physician Yash Khandwala, MD, is the lead author.
Increased risks at 35
Back in 2017, Eisenberg published a study showing that the number of older men fathering children was on the rise. Now, about 10 percent of infants are born to fathers over the age of 40, whereas four decades ago it was only 4 percent.
“We’re seeing these shifts across the United States, across race strata, across education levels, geography — everywhere you look, the same patterns are being seen,” Eisenberg said. “So I do think it’s becoming more relevant for us to understand the health ramifications of advanced paternal age on infant and maternal health.”
Having a better understanding of the father’s biological role will be obviously important for the offspring, but also potentially for the mother.
Eisenberg and his colleagues used data from 40.5 million live births documented through a data-sharing program run by the Centers for Disease Control and Prevention and the National Center for Health Statistics. The researchers organized the information based on the fathers’ age — younger than 25; 25 to 34; 35 to 44; 45 to 55; and older than 55 — and controlled for a variety of parameters that might skew the association between the father’s age and birth outcomes, such as race, education level, marital status, smoking history, access to care and the mother’s age.
The data suggested that once a dad hits age 35, there’s a slight increase in birth risks overall — with every year that a man ages, he accumulates on average two new mutations in the DNA of his sperm — but birth risks for infants born to fathers of the subsequent age tier showed sharper increases.
Compared with fathers between the ages of 25 and 34 (the average age of paternity in the United States), infants born to men 45 or older were 14 percent more likely to be admitted to the NICU, 14 percent more likely to be born prematurely, 18 percent more likely to have seizures and 14 percent more likely to have a low birth weight. If a father was 50 or older, the likelihood that their infant would need ventilation upon birth increased by 10 percent, and the odds that they would need assistance from the neonatal intensive care unit increased by 28 percent.
“What was really surprising was that there seemed to be an association between advanced paternal age and the chance that the mother would develop diabetes during pregnancy,” said Eisenberg. For men age 45 and older, their partners were 28 percent more likely to develop gestational diabetes, compared with fathers between 25 and 34. Eisenberg points out that possible biological mechanisms at play here are still a bit murky, but he suspects that the mother’s placenta has a role.
Beyond correlation
Moving forward, Eisenberg wants to look into other population cohorts to confirm the associations between age and birth risks, as well as begin to decode some of the possible biological mechanisms.
“Scientists have looked at these kinds of trends before, but this is the most comprehensive study to look at the relationship between the father’s age and birth outcomes at a population level,” said Eisenberg. “Having a better understanding of the father’s biological role will be obviously important for the offspring, but also potentially for the mother.”
Other Stanford co-authors of the study are professor of obstetrics and gynecology Valerie Baker, MD; professor of pediatrics Gary Shaw, DrPH; professor of pediatrics David K. Stevenson, MD; and professor of biomedical data, Ying Lu, PhD.
Eisenberg is a member of Stanford Bio-X, the Stanford Child Health Research Institute and the Stanford Cancer Institute.

There are benefits and cautions for those becoming parents after 35.

Dinah Wisenberg Brin wrote in the CNBC article Older-Parent Families: Advantages and Disadvantages:

Beyond the retirement and college-planning decisions, middle-aged parents may be caring for their own frail, elderly parents at the same time they’re raising preschoolers, a potentially costly prospect that points to another issue: No built-in support network of youthful grandparents who can babysit during parental getaways. CFP Kahler knows this first hand.
“Our childcare bill is as much as our airfare bill,” he says. Trading childcare with other families can defrays the costs, though, he adds.
The age factor similarly can make it difficult for middle-age parents to find willing and able guardians to name in their wills. Lindsay recalls a former client couple in their 40s with young children who had trouble completing their estate planning because they had only older siblings and no one willing to be named as guardians.
“Sometimes it just comes down to making the best decision out of a number of poor alternatives,” Kahler says. “It may mean sending them out of state to someone, you may be looking to nieces and nephews who could potentially raise a child.”
Older-parent families can face other advantages and disadvantages, as well.
“I think my kids will need less therapy than if I’d had kids in my 20s,” Kahler jokes. On the other hand, he notes there are costs associated with the care of an aging body. “I tell my kids, `The horsey can only go up and down the hallway a couple of times before the horsey runs out of gas.’ ” https://www.cnbc.com/id/44378785

Infectious Diseases Society of America study: Fatal measles case highlights importance of herd immunity in protecting the vulnerable

4 Nov

The Centers for Disease Control and Prevention (CDC) lay out the case for vaccination:
Why Are Childhood Vaccines So Important?

It is always better to prevent a disease than to treat it after it occurs.
Diseases that used to be common in this country and around the world, including polio, measles, diphtheria, pertussis (whooping cough), rubella (German measles), mumps, tetanus, rotavirus and Haemophilus influenzae type b (Hib) can now be prevented by vaccination. Thanks to a vaccine, one of the most terrible diseases in history – smallpox – no longer exists outside the laboratory. Over the years vaccines have prevented countless cases of disease and saved millions of lives.
Immunity Protects us From Disease
Immunity is the body’s way of preventing disease. Children are born with an immune system composed of cells, glands, organs, and fluids located throughout the body. The immune system recognizes germs that enter the body as “foreign invaders” (called antigens) and produces proteins called antibodies to fight them.
The first time a child is infected with a specific antigen (say measles virus), the immune system produces antibodies designed to fight it. This takes time . . . usually the immune system can’t work fast enough to prevent the antigen from causing disease, so the child still gets sick. However, the immune system “remembers” that antigen. If it ever enters the body again, even after many years, the immune system can produce antibodies fast enough to keep it from causing disease a second time. This protection is called immunity.
It would be nice if there were a way to give children immunity to a disease without their having to get sick first.
In fact there is:
Vaccines contain the same antigens (or parts of antigens) that cause diseases. For example, measles vaccine contains measles virus. But the antigens in vaccines are either killed, or weakened to the point that they don’t cause disease. However, they are strong enough to make the immune system produce antibodies that lead to immunity. In other words, a vaccine is a safer substitute for a child’s first exposure to a disease. The child gets protection without having to get sick. Through vaccination, children can develop immunity without suffering from the actual diseases that vaccines prevent.
More Facts
• Newborn babies are immune to many diseases because they have antibodies they got from their mothers. However, this immunity goes away during the first year of life.
• If an unvaccinated child is exposed to a disease germ, the child’s body may not be strong enough to fight the disease. Before vaccines, many children died from diseases that vaccines now prevent, such as whooping cough, measles, and polio. Those same germs exist today, but because babies are protected by vaccines, we don’t see these diseases nearly as often.
• Immunizing individual children also helps to protect the health of our community, especially those people who cannot be immunized (children who are too young to be vaccinated, or those who can’t receive certain vaccines for medical reasons), and the small proportion of people who don’t respond to a particular vaccine.
• Vaccine-preventable diseases have a costly impact, resulting in doctor’s visits, hospitalizations, and premature deaths. Sick children can also cause parents to lose time from work. https://www.cdc.gov/vaccines/vac-gen/howvpd.htm

A key component of the effectiveness of the effectiveness of vaccines is herd protection.

PBS NOVA reported in What is Herd Immunity?

What is “herd immunity?”
Just as a herd of cattle or sheep uses sheer numbers to protect its members from predators, herd immunity protects a community from infectious diseases by virtue of the sheer numbers of people immune to such diseases. The more members of a human “herd” who are immune to a given disease, the better protected the whole populace will be from an outbreak of that disease.
There are two ways an individual can become immune to an infectious disease: by becoming infected with the pathogen that causes it or by being vaccinated against it. Because vaccines induce immunity without causing illness, they are a comparatively safe and effective way to fill a community with disease-resistant people. These vaccinated individuals have protected themselves from disease. But, in turn, they are also protecting members of the community who cannot be vaccinated, preventing the chain of disease from reaching them and limiting potential outbreaks. Every vaccinated person adds to the effectiveness of this community-level protection.
What do thresholds have to do with herd immunity?
The microbes that cause disease all have different infectious features. Some, like measles and influenza, pass from person to person more easily than others. Some tend to have more severe consequences in specific demographic groups. For example, the symptoms of pertussis, or whooping cough, are distressing at any age but can be fatal in infants, the age group with the highest death rate from pertussis. Each of these features—such as transmissibility and severity—affects a given disease’s threshold, or the minimum percentage of immune individuals a community needs to prevent an outbreak.
To set a threshold, epidemiologists—experts in infectious disease transmission—use a value called “basic reproduction number,” often referred to as “R0.” This number represents how many people in an unprotected population one infected person could pass the disease along to. For example, R0 for measles is between 12 and 18, while for polio, it is between five and seve. The higher this number is, the higher the immunity threshold must be to protect the community. Because measles is extremely contagious and can spread through the air, for example, the immunity threshold needed to protect a community is high, at 95%. Diseases like polio, which are a little less contagious, have a lower threshold—80% to 85% in the case of polio….. https://www.pbs.org/wgbh/nova/article/herd-immunity/

Infectious Diseases Society of America (IDSA) reported about the importance of herd protection in cases where a disease can prove fatal with out herd protection.

Science Daily reported in Fatal measles case highlights importance of herd immunity in protecting the vulnerable:

Last year, a 26-year-old man receiving treatment for leukemia went to a Swiss hospital’s emergency room with a fever, a sore throat, and a cough, and was admitted. His condition worsened, and 17 days later, he died from severe complications of measles. The man’s weakened immune system was unable to fight off the disease, even though he was vaccinated against measles as a child.
A new report in Open Forum Infectious Diseases describes the man’s case, highlighting the importance of maintaining high vaccination coverage in the community to help protect people with compromised immune systems from measles and other vaccine-preventable infections. “Measles is not harmless, it’s a serious disease,” said the report’s lead author, Philipp Jent, MD, of Bern University Hospital and the University of Bern in Switzerland. “There is a responsibility to vaccinate yourself to protect others, not only to protect yourself.”
Following the patient’s admission in February of 2017, he developed additional symptoms over the next several days, including a progressive rash, mouth sores, and conjunctivitis, that suggested measles, although he had been fully vaccinated against the disease with the recommended two doses of the measles, mumps, and rubella (MMR) vaccine in the 1990s. A throat swab test confirmed the measles infection. Treatment with ribavirin (an antiviral drug), immunoglobulins (a type of antibody), and vitamin A did not improve his condition. He subsequently developed severe pneumonia and died.
The case illustrates how serious measles can be, particularly for people with compromised immune systems due to cancer treatment or other causes. It also underscores the importance of herd immunity in protecting these vulnerable individuals, the report’s authors noted. When vaccination rates in a community are high enough, vaccine-preventable diseases like measles are less likely to spread, which helps protect those who cannot be vaccinated (such as newborns not old enough to be immunized) or, like the patient in this case, for whom vaccines are not as effective.
When the proportion of people in a community who are vaccinated drops below this threshold, however, as it has for measles immunizations in several European countries, outbreaks are more likely. More than 41,000 children and adults in Europe were infected with measles during the first half of 2018, according to the World Health Organization, exceeding the annual total of European cases reported in any previous year this decade. In the U.S., there had been 142 confirmed cases of measles in 2018 as of early October, according to the U.S. Centers for Disease Control and Prevention (CDC). Data released by CDC in October also showed a gradual but concerning climb in the numbers of U.S. children who reach their second birthday without having received any recommended vaccines…. https://www.sciencedaily.com/releases/2018/11/181101133918.htm

“Ongoing efforts to raise confidence in vaccines and increase population immunity should be intensified,” the authors wrote in the case report’s conclusion. Physicians caring for people with compromised immune systems, the authors noted, should also ensure that those in close contact with these patients, such as family members and friends, are fully vaccinated.
Fast Facts
• People with weakened immune systems are at risk for contracting vaccine-preventable diseases, such as measles, even if they have been vaccinated.
• In this case, a 26-year-old Swiss man undergoing treatment for leukemia contracted measles and died from severe complications of the infection, despite being fully vaccinated against measles as a child.
• Maintaining high enough levels of vaccination coverage in the broader community, also known as herd immunity, can limit the spread of measles and other diseases and help protect those who are especially vulnerable.

There is an ongoing public debate about possible risks of vaccination for some individuals vs. the greater good of vaccination for the commons.

Kevin M. Malone and Alan R. Hinman wrote in Chapter 13 of Vaccination Mandates: The Public Health Imperative and Individual Rights:

BACKGROUND
Concept for Community Disease Prevention
Garrett Hardin’s classic essay The Tragedy of the Commons3 describes the challenges presented when societal interest conflicts with the individual’s interest. Hardin notes the incentives present when the cattle of a community are commingled in a common pasture. At capacity, each owner still has an incentive to add additional cattle to the common because even though the yield from each animal decreases with the addition of more cattle, this decrease is offset for the individual owner by the additional animal. With this incentive, individual owners continue to add cattle to the commons to reap their individual benefit, leading to the inevitable failure of the common from overgrazing. The community interest in maximizing food production, therefore, can be achieved only by placing controls on the interests of the individual owners in favor of those of the community. Analogously, a community free of an infectious disease because of a high vaccination rate can be viewed as a common. As in Hardin’s common, the very existence of this common leads to tension between the best interests of the individual and those of the community. Increased immunization rates result in significantly decreased risk for disease. Although no remaining unimmunized individual can be said to be free of risk from the infectious disease, the herd effect generated from high immunization rates significantly reduces the risk for disease for those individuals. Additional benefit is conferred on the unimmunized person because avoidance of the vaccine avoids the risk for any adverse reactions associated with the vaccine. As disease rates drop, the risks associated with the vaccine come even more to the fore, providing further incentive to avoid immunization. Thus, when an individual in this common chooses to go unimmunized, it only minimally increases the risk of illness for that individual, while conferring on that person the benefit of avoiding the risk of vaccine induced side effects. At the same time, however, this action weakens the herd effect protection for the entire community. As more and more individuals choose to do what is in their “best” individual interest, the common eventually fails as herd immunity disappears and disease outbreaks occur. To avoid this “tragedy of the commons,” legal requirements have been imposed by communities (in recent times, by states) to mandate particular vaccinations.
Vaccine Safety and Effectiveness
Vaccines are safe and effective. However, they are neither perfectly safe nor perfectly effective. Consequently, some persons who receive vaccines will be injured as a result, and some persons who receive vaccines will not be protected. Most adverse events associated with vaccines are minor and involve local soreness or redness at the injection site or perhaps fever for a day or so. Rarely, however, vaccine can cause more serious adverse events. Whether an adverse event that occurs after vaccination was caused by the vaccine or was merely temporally related and caused by some totally independent (and often unknown or unidentified) factor is often difficult to ascertain. This is particularly problematic during infancy, when a number of conditions may occur spontaneously…. https://www.cdc.gov/vaccines/imz-managers/guides-pubs/downloads/vacc_mandates_chptr13.pdf

The issue for those balancing individual decision-making and the needs of public health are how much coercion is necessary to compel individual vaccination with the goal of protecting public health.

Ohio State University study: Why relationships — not money — are the key to improving schools

28 Oct

In New research: School principal effectiveness, moi said: The number one reason why teachers leave the profession has to do with working conditions. A key influencer of the environment of a school and the working conditions is the school principal.
Gregory Branch, Eric Hanushek, and Steven Rivkin are reporting in the National Centerfor Analysis of Longitudinal Data in Educational Research report, Estimating Principal Effectiveness:

VI. Conclusion
An important facet of many school policy discussions is the role of strong leadership, particularly of principals. Leadership is viewed as especially important in revitalizing failing schools. This discussion is, however, largely uninformed by systematic analysis of principals and their impact on student outcomes….
The initial results suggest that principal movements parallel teacher movements. Specifically, principals are affected by the racial and achievement distribution of students in schools, and this enters into mobility patterns. Yet the common view that the best leave the most needy schools is not supported.
An important element of the role of principals is how they interact with teachers. Our on-going analysis links principals to measures of teacher effectiveness to understand how principals affect teacher outcomes. http://www.caldercenter.org/upload/CALDER-Working-Paper-32_FINAL.pdf
See, Principals Matter: School Leaders Can Drive Student Learning http://www.huffingtonpost.com/Karin%20Chenoweth/principals-matter-school-_b_1252598.html?ref=email_share

In lay person speak; what they are saying is that a strong principal is a strong leader for his or her particular school. A strong principal is particularly important in schools which face challenges. Now, we get into the manner in which strong principals interact with their staff – is it an art or is it a science? What makes a good principal can be discussed and probably depends upon the perspective of those giving an opinion, but Gary Hopkins of Education World summarizes the thoughts of some educators:

Top Ten Traits of School Leaders
Last month, 43 of the Education World Principal Files principals participated in a survey. The result of that survey is this list of the top ten traits of school leaders, presented in order of importance.
1. Has a stated vision for the school and a plan to achieve that vision.
2. Clearly states goals and expectations for students, staff, and parents.
3. Is visible — gets out of the office; is seen all over the school.
4. Is trustworthy and straight with students and staff.
5. Helps develop leadership skills in others.
6. Develops strong teachers; cultivates good teaching practice.
7. Shows that he or she is not in charge alone; involves others.
8. Has a sense of humor.
9. Is a role model for students and staff.
10. Offers meaningful kindnesses and kudos to staff and students.
http://www.educationworld.com/a_admin/admin/admin190.shtml

These traits can be summarized that a strong principal is a leader with a vision for his or her school and who has the drive and the people skills to take his or her teachers and students to that vision. https://drwilda.wordpress.com/2012/02/07/new-research-school-principal-effectiveness/

Science Daily reported in Why relationships — not money — are the key to improving schools:

Strong relationships between teachers, parents and students at schools has more impact on improving student learning than does financial support, new research shows.

Social capital is the name scientists give to the network of relationships between school officials, teachers, parents and the community that builds trust and norms promoting academic achievement.
The study found that social capital had a three- to five-times larger effect than financial capital on reading and math scores in Michigan schools.

“When we talk about why some schools perform better than others, differences in the amount of money they have to spend is often assumed to be an explanation,” said Roger Goddard, co-author of the study and Novice G. Fawcett Chair and professor of educational administration at The Ohio State University.
“We found that money is certainly important. But this study also shows that social capital deserves a larger role in our thinking about cost-effective ways to support students, especially the most vulnerable.”
Goddard conducted the research with Serena Salloum of Ball State University and Dan Berebitsky of Southern Methodist University. The study appears online in the Journal of Education for Students Placed at Risk and will be published in a future print edition.
The study involved 5,003 students and their teachers in 78 randomly selected public elementary schools in Michigan. The sample is representative of the demographics of all elementary schools in the state.
Teachers completed a questionnaire that measured levels of social capital in their schools. They rated how much they agreed with statements like “Parent involvement supports learning here,” “Teachers in this school trust their students” and “Community involvement facilitates learning here.”
State data on instructional expenditures per pupil was used to measure financial capital at each school.
Finally, the researchers used student performance on state-mandated fourth-grade reading and mathematics tests to measure student learning.
Results showed that on average schools that spent more money did have better test scores than those that spent less. But the effect of social capital was three times larger than financial capital on math scores and five times larger on reading scores….. https://www.sciencedaily.com/releases/2018/10/181025103300.htm

Why relationships — not money — are the key to improving schools
Study finds social capital has 3-5 times the impact of funding
OHIO STATE UNIVERSITY
COLUMBUS, Ohio – Strong relationships between teachers, parents and students at schools has more impact on improving student learning than does financial support, new research shows.
Social capital is the name scientists give to the network of relationships between school officials, teachers, parents and the community that builds trust and norms promoting academic achievement.
The study found that social capital had a three- to five-times larger effect than financial capital on reading and math scores in Michigan schools.
“When we talk about why some schools perform better than others, differences in the amount of money they have to spend is often assumed to be an explanation,” said Roger Goddard, co-author of the study and Novice G. Fawcett Chair and professor of educational administration at The Ohio State University.
“We found that money is certainly important. But this study also shows that social capital deserves a larger role in our thinking about cost-effective ways to support students, especially the most vulnerable.”
Goddard conducted the research with Serena Salloum of Ball State University and Dan Berebitsky of Southern Methodist University. The study appears online in the Journal of Education for Students Placed at Risk and will be published in a future print edition.
The study involved 5,003 students and their teachers in 78 randomly selected public elementary schools in Michigan. The sample is representative of the demographics of all elementary schools in the state.
Teachers completed a questionnaire that measured levels of social capital in their schools. They rated how much they agreed with statements like “Parent involvement supports learning here,” “Teachers in this school trust their students” and “Community involvement facilitates learning here.”
State data on instructional expenditures per pupil was used to measure financial capital at each school.
Finally, the researchers used student performance on state-mandated fourth-grade reading and mathematics tests to measure student learning.
Results showed that on average schools that spent more money did have better test scores than those that spent less. But the effect of social capital was three times larger than financial capital on math scores and five times larger on reading scores.
“Social capital was not only more important to learning than instructional expenditures, but also more important than the schools’ poverty, ethnic makeup or prior achievement,” Goddard said.
While social capital tended to go down in schools as poverty levels increased, it wasn’t a major decrease.
“We could see from our data that more than half of the social capital that schools have access to has nothing to do with the level of poverty in the communities they serve,” he said.
“Our results really speak to the importance and the practicality of building social capital in high-poverty neighborhoods where they need it the most.”
The study also found that the money spent on student learning was not associated with levels of social capital in schools. That means schools can’t “buy” social capital just by spending more money. Social relationships require a different kind of investment, Goddard said.
The study can’t answer how to cultivate social capital in schools. But Goddard has some ideas.
One is for schools to do more to help teachers work together.
“Research shows that the more teachers collaborate, the more they work together on instructional improvement, the higher the test scores of their students. That’s because collaborative work builds social capital that provides students with access to valuable support,” he said.
Building connections to the community is important, too. School-based mentoring programs that connect children to adults in the community is one idea.
“Sustained interactions over time focused on children’s learning and effective teaching practice are the best way for people to build trust and build networks that are at the heart of social capital,” Goddard said.
“We need intentional effort by schools to build social capital. We can’t leave it to chance.”

Schools must be relentless about the basics for their population of kids.

What does it mean to Be Relentless about the Basics?
1. Students acquire strong subject matter skills in reading, writing, and math.
2. Students are assessed often to gauge where they are in acquiring basic skills.
3. If there are deficiencies in acquiring skills, schools intervene as soon as a deficiency assessment is made.
4. Schools intervene early in life challenges faced by students which prevent them from attending school and performing in school.
5. Appropriate corrective assistance is provided by the school to overcome both academic and life challenges.

University of Illinois at Chicago study: How to avoid raising a materialistic child

21 Oct

George Monbiot wrote in the article, Materialism: a system that eats us from the inside out:

There has long been a correlation observed between materialism, a lack of empathy and engagement with others, and unhappiness. But research conducted over the past few years seems to show causation. For example, a series of studies published in the journal Motivation and Emotion in July showed that as people become more materialistic, their wellbeing (good relationships, autonomy, sense of purpose and the rest) diminishes. As they become less materialistic, it rises….
A third paper, published (paradoxically) in the Journal of Consumer Research, studied 2,500 people for six years. It found a two-way relationship between materialism and loneliness: materialism fosters social isolation; isolation fosters materialism. People who are cut off from others attach themselves to possessions. This attachment in turn crowds out social relationships.
The two varieties of materialism that have this effect – using possessions as a yardstick of success and seeking happiness through acquisition – are the varieties that seem to be on display on Rich Kids of Instagram. It was only after reading this paper that I understood why those photos distressed me: they look like a kind of social self-mutilation.
Perhaps this is one of the reasons an economic model based on perpetual growth continues on its own terms to succeed, though it may leave a trail of unpayable debts, mental illness and smashed relationships. Social atomisation may be the best sales strategy ever devised, and continuous marketing looks like an unbeatable programme for atomisation.
Materialism forces us into comparison with the possessions of others, a race both cruelly illustrated and crudely propelled by that toxic website. There is no end to it. If you have four Rolexes while another has five, you are a Rolex short of contentment. The material pursuit of self-esteem reduces your self-esteem.
I should emphasise that this is not about differences between rich and poor: the poor can be as susceptible to materialism as the rich. It is a general social affliction, visited upon us by government policy, corporate strategy, the collapse of communities and civic life, and our acquiescence in a system that is eating us from the inside out.
This is the dreadful mistake we are making: allowing ourselves to believe that having more money and more stuff enhances our wellbeing, a belief possessed not only by those poor deluded people in the pictures, but by almost every member of almost every government. Worldly ambition, material aspiration, perpetual growth: these are a formula for mass unhappiness…. https://www.theguardian.com/commentisfree/2013/dec/09/materialism-system-eats-us-from-inside-out

University of Illinois Chicago researchers studied how to avoid raising a materialistic child.

Science Daily reported in How to avoid raising a materialistic child:

If you’re a parent, you may be concerned that materialism among children has been on the rise. According to research, materialism has been linked to a variety of mental health problems, such as anxiety and depression, as well as selfish attitudes and behaviors.
But there’s some good news. A new study published in the Journal of Positive Psychology suggests that some parenting tactics can curb kids’ materialistic tendencies.
“Our findings show that it is possible to reduce materialism among young consumers, as well as one of its most common negative consequences (nongenerosity) using a simple strategy — fostering gratitude for the things and people in their lives,” writes researcher Lan Nguyen Chaplin, associate professor of marketing at the University of Illinois at Chicago and coauthor of the study.
After studying a nationwide sample of more than 900 adolescents ages 11 to 17, Chaplin’s team found a link between fostering gratitude and its effects on materialism, suggesting that having and expressing gratitude may possibly decrease materialism and increase generosity among adolescents.
The team surveyed 870 adolescents and asked them to complete an online eight-item measure of materialism assessing the value placed on money and material goods, and a four-item measure of gratitude assessing how thankful they are for people and possessions in their lives.
The researchers then conducted an experiment among 61 adolescents and asked them to complete the same four-item gratitude measure from the first study and an eight-item materialism measure. The adolescents were randomly assigned to keep a daily journal for two weeks. One group was asked to record who and what they were thankful for each day by keeping a gratitude journal, and the control group was asked to record their daily activities.
After two weeks, the journals were collected and the participants completed the same gratitude and materialism measures as before. The kids were then given 10 $1 bills for participating and told they could keep all the money or donate some or all of it to charity.
Results showed that participants who were encouraged to keep a gratitude journal showed a significant decrease in materialism and increase in gratitude. The control group, which kept the daily activity journal, retained their pre-journal levels of gratitude and materialism.
In addition, the group that kept a gratitude journal was more generous than the control group. Adolescents, who were in the experimental group, wrote about who and what they were thankful for and donated more than two-thirds of their earnings. Those who were in the control group and simply wrote about their daily activities donated less than half of their earnings.
“The results of this survey study indicate that higher levels of gratitude are associated with lower levels of materialism in adolescents across a wide range of demographic groups,” Chaplin noted…. https://www.sciencedaily.com/releases/2018/10/181019100606.htm

The authors also suggest that materialism can be curbed and feelings of gratitude can be enhanced by a daily gratitude reflection around the dinner table, having children and adolescents make posters of what they are grateful for, or keeping a “gratitude jar” where children and teens write down something they are grateful for each week, while countering materialism.

A key component of materialism is the level of gratitude an individual possesses.

Lifeworks wrote in Depression more prevalent in the Western world:

According to a new World Health Organization (WHO) study, published on July 25 in the journal of BMC medicine, not only are depression rates significantly higher in affluent nations but cases of major depression are on the rise throughout the world. The study concludes that depression is a severe global problem that will change from being the world’s fourth leading cause of disability worldwide, to being the second leading cause of disability by 2020. But how are we to explain these concerning findings.
The link between affluence and stress
The WHO study found that 15% of people in high income countries were likely to face an episode of depression in their lifetime, compared to 11% of people in low income countries. The highest instances of people that faced clinical depression once in their lifetime was found in France, Netherlands, New Zealand, and the United States. These figures are in stark contrast to countries such as China and Mexico, which were found to have the lowest incidences of depression.
The researchers of the study speculate that stress might be a significant factor in the differences in the prevalence rates. Stress is known to be one of the main triggers of depression, and in nations such as the UK a still growing number of men and women succumb to the pressures that seem embedded in our value system and societal structure. The study found an important gender disparity with regards to depression, with women having a twofold increased risk of having major depressive episodes, which might in part explain why affluent nations, in which women are working and making home, stress and depression are more prevalent…. https://www.lifeworkscommunity.com/mental-health-knowledge-centre/depression/depression-in-the-western-world.html

Perhaps, what is missing is gratitude.

Robert Emmons wrote Why Gratitude Is Good:

We’ve studied more than one thousand people, from ages eight to 80, and found that people who practice gratitude consistently report a host of benefits:
Physical
• Stronger immune systems
• Less bothered by aches and pains
• Lower blood pressure
• Exercise more and take better care of their health
• Sleep longer and feel more refreshed upon waking
Psychological
• Higher levels of positive emotions
• More alert, alive, and awake
• More joy and pleasure
• More optimism and happiness
Social
• More helpful, generous, and compassionate
• More forgiving
• More outgoing
• Feel less lonely and isolated.
The social benefits are especially significant here because, after all, gratitude is a social emotion. I see it as a relationship-strengthening emotion because it requires us to see how we’ve been supported and affirmed by other people.
Indeed, this cuts to very heart of my definition of gratitude, which has two components. First, it’s an affirmation of goodness. We affirm that there are good thing in the world, gifts and benefits we’ve received. This doesn’t mean that life is perfect; it doesn’t ignore complaints, burdens, and hassles. But when we look at life as a whole, gratitude encourages us to identify some amount of goodness in our life…. https://greatergood.berkeley.edu/article/item/why_gratitude_is_good

Many of the happiest individuals cultivate an attitude of gratitude. See, Wynne Parry’s 7 Tips to Cultivate Gratitude https://www.livescience.com/25900-7-tips-gratitude-happiness.html

University of Maryland Baltimore County study: New method to address deep-seated biases in science

18 Oct

The New York Times reported in Hoaxers Slip Breastaurants and Dog-Park Sex Into Journals:

One paper, published in a journal called Sex Roles, said that the author had conducted a two-year study involving “thematic analysis of table dialogue” to uncover the mystery of why heterosexual men like to eat at Hooters.
Another, from a journal of feminist geography, parsed “human reactions to rape culture and queer performativity” at dog parks in Portland, Ore., while a third paper, published in a journal of feminist social work and titled “Our Struggle Is My Struggle,” simply scattered some up-to-date jargon into passages lifted from Hitler’s “Mein Kampf.”
Such offerings may or may not have raised eyebrows among the journals’ limited readerships. But this week, they unleashed a cascade of mockery — along with a torrent of debate about ethics of hoaxes, the state of peer review and the excesses of academia — when they were revealed to be part of an elaborate prank aimed squarely at what the authors labeled “grievance studies.”
“Something has gone wrong in the university — especially in certain fields within the humanities,” the three authors of the fake papers wrote in an article in the online journal Areo explaining what they had done. “Scholarship based less upon finding truth and more upon attending to social grievances has become firmly established, if not fully dominant, within these fields.”
Their project quickly drew comparisons to a famous 1996 hoax in which the physicist Alan Sokal got a paper mixing postmodern philosophy with the theory of quantum gravity into a prestigious cultural studies journal.
But while that hoax involved a single article, the new one involved 20 papers, produced every two weeks or so, submitted to various journals over nearly a year.
The authors — Helen Pluckrose, James A. Lindsay and Peter Boghossian — said that four papers had been published; three had been accepted but not yet published; seven were under review and six had been rejected…. https://www.nytimes.com/2018/10/04/arts/academic-journals-hoax.html

Scientific method is important because it directs inquiry into a rational discussion and outcome.

William Harris wrote in How the Scientific Method Works:

Importance of the Scientific Method
The scientific method attempts to minimize the influence of bias or prejudice in the experimenter. Even the best-intentioned scientists can’t escape bias. It results from personal beliefs, as well as cultural beliefs, which means any human filters information based on his or her own experience. Unfortunately, this filtering process can cause a scientist to prefer one outcome over another. For someone trying to solve a problem around the house, succumbing to these kinds of biases is not such a big deal. But in the scientific community, where results have to be reviewed and duplicated, bias must be avoided at all costs.
¬T¬hat’s the job of the scientific method. It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results. By using a standardized approach in their investigations, scientists can feel confident that they will stick to the facts and limit the influence of personal, preconceived notions. Even with such a rigorous methodology in place, some scientists still make mistakes. For example, they can mistake a hypothesis for an explanation of a phenomenon without performing experiments. Or they can fail to accurately account for errors, such as measurement errors. Or they can ignore data that does not support the hypothesis…. https://science.howstuffworks.com/innovation/scientific-experiments/scientific-method9.htm

A University of Maryland Baltimore County (UMBC) examined biases in scientific research.

Science Daily reported in New method to address deep-seated biases in science:

New UMBC research is helping dismantle gender and publication biases in science. A team of researchers working across disciplines has developed a new statistical technique to understand similarity, rather than difference, in the natural world. With this new technique, they’ve determined that among Eastern Bluebirds the structure of songs female birds sing is statistically indistinguishable from songs males sing….
Challenging a paradigm
Working together, the team modified a statistical method used in generic drug testing to meet their needs for ecology and animal behavior studies. The existing test helps determine whether generic and brand name drugs are “statistically equivalent,” meaning they are similar enough to be prescribed safely for the same purpose. The new modification will allow scientists in other fields to test for equivalence. Before, researchers could only report they did not find a significant difference — a very different statement than saying two things are conclusively equivalent.
“We’re really hoping this new method is going to address some issues with what kinds of data get published,” Rose says. “The most important thing about being a good scientist is to be unbiased. And the whole tradition of testing for difference really leads to incredible biases in scientists,” Omland says. He adds, “There’s a whole realm of things in nature that we find interesting and important because of their similarity.”
For example, in addition to similarities in songs between the sexes in birds, researchers could use the new test to ask if two species use the same type of habitat, respond the same way to predators, or consume the same food sources. Answers to those questions could fill long-standing knowledge gaps, or even inform conservation efforts.
“This test is really broadly applicable,” says Rose, “and we’re hoping to introduce it more to the ecology and evolution field.”
A new approach
One advantage of the new method is it accounts for unequal sample sizes. In a medical study, researchers can carefully control the size of treatment and control groups.

Summary:
A new statistical method that tests for equivalence, rather than difference, has a role to play in dismantling gender and publication biases in science. The authors believe the technique has broad applicability across disciplines and can help remove publication bias against ”negative results,” opening the door to a broader investigation of natural phenomena.

Here is the press release from UMBC:

New methods to fight biases in science, starting with birds
October 18, 2018 1:28 PM
New UMBC research is helping dismantle gender and publication biases in science. A team of researchers working across disciplines has developed a new statistical technique to understand similarity, rather than difference, in the natural world. With this new technique, they’ve determined that among Eastern Bluebirds the structure of songs female birds sing is statistically indistinguishable from songs males sing.
Awareness of female birdsong is growing worldwide, thanks in part to a breakthrough paper by Karan Odom, Ph.D. ’16, biological sciences, but it’s still understood as a trait found primarily in tropical birds. Evangeline Rose, a current Ph.D. student in the same lab and first author on a new paper in Animal Behavior, wanted to look at song in a temperate species.
During Rose’s fieldwork, “I was finding that the females were singing, to me, what sounded just like male songs,” she says. “So we started thinking about equality, and equivalence, and how to test for it.” On the advice of her advisor, Kevin Omland, professor of biological sciences, she reached out to Thomas Mathew, professor of statistics, who has expertise in statistical equivalence.
Challenging a paradigm
Working together, the team modified a statistical method used in generic drug testing to meet their needs for ecology and animal behavior studies. The existing test helps determine whether generic and brand name drugs are “statistically equivalent,” meaning they are similar enough to be prescribed safely for the same purpose. The new modification will allow scientists in other fields to test for equivalence. Before, researchers could only report they did not find a significant difference—a very different statement than saying two things are conclusively equivalent.
“We’re really hoping this new method is going to address some issues with what kinds of data get published,” Rose says. “The most important thing about being a good scientist is to be unbiased. And the whole tradition of testing for difference really leads to incredible biases in scientists,” Omland says. He adds, “There’s a whole realm of things in nature that we find interesting and important because of their similarity.”
For example, in addition to similarities in songs between the sexes in birds, researchers could use the new test to ask if two species use the same type of habitat, respond the same way to predators, or consume the same food sources. Answers to those questions could fill long-standing knowledge gaps, or even inform conservation efforts.
“This test is really broadly applicable,” says Rose, “and we’re hoping to introduce it more to the ecology and evolution field.”
A new approach
One advantage of the new method is it accounts for unequal sample sizes. In a medical study, researchers can carefully control the size of treatment and control groups. In other fields, from ecology, to engineering, to agriculture, that’s often not possible. The new test also allows researchers to determine the equivalence of several traits simultaneously, Mathew explains. For example, in this study, the authors found that the male and female birds’ songs were statistically equivalent across five different characteristics, such as duration of each song and the range of pitches the birds produced.
Rather than testing whether two things are exactly equal, the team was looking for a way to determine if two things were “close enough,” given a defined allowable margin of difference. Because of that added layer, “There are additional challenges here,” Mathew says.
“Even though this methodology is out there, it hasn’t been applied—even in statistics—with this kind of data. That’s why I was very excited when they brought this project to me,” Mathew says. Rose adds, “It ended up being a really great partnership to look at these questions that hadn’t been asked before for female song, and we also ended up modifying this test in a really cool, new way.”
Changing science
As research on similarities grows, there is also a growing drive to remove the bias against publishing studies that do not find a significant difference, often termed a “negative result.” This paper “is part of an amazing drumbeat that’s building up in the scientific community,” Omland says. “There’s a broader problem with the scientific method that’s being increasingly acknowledged, and the test we’ve developed can at least play a small role, and I hope a big role, in addressing it.”
Rose, who plans to next investigate the function of female bluebird songs, says she will carry these new techniques with her as she moves through her research career. “I think in the future, I’ll be thinking about how equivalence can change the questions we’re asking, and I’ll always keep in mind that we have extra tools in the toolkit.”

Honesty in scientific research protocol is essential.

David B. Resnik, J.D., Ph.D. wrote in What is Ethics in Research & Why is it Important?

The following is a rough and general summary of some ethical principals that various codes address*:
Honesty
Strive for honesty in all scientific communications. Honestly report data, results, methods and procedures, and publication status. Do not fabricate, falsify, or misrepresent data. Do not deceive colleagues, research sponsors, or the public.
Objectivity
Strive to avoid bias in experimental design, data analysis, data interpretation, peer review, personnel decisions, grant writing, expert testimony, and other aspects of research where objectivity is expected or required. Avoid or minimize bias or self-deception. Disclose personal or financial interests that may affect research.
Integrity
Keep your promises and agreements; act with sincerity; strive for consistency of thought and action.
Carefulness
Avoid careless errors and negligence; carefully and critically examine your own work and the work of your peers. Keep good records of research activities, such as data collection, research design, and correspondence with agencies or journals.
Openness
Share data, results, ideas, tools, resources. Be open to criticism and new ideas.
Respect for Intellectual Property
Honor patents, copyrights, and other forms of intellectual property. Do not use unpublished data, methods, or results without permission. Give proper acknowledgement or credit for all contributions to research. Never plagiarize.
Confidentiality
Protect confidential communications, such as papers or grants submitted for publication, personnel records, trade or military secrets, and patient records.
Responsible Publication
Publish in order to advance research and scholarship, not to advance just your own career. Avoid wasteful and duplicative publication.
Responsible Mentoring
Help to educate, mentor, and advise students. Promote their welfare and allow them to make their own decisions.
Respect for colleagues
Respect your colleagues and treat them fairly.
Social Responsibility
Strive to promote social good and prevent or mitigate social harms through research, public education, and advocacy.
Non-Discrimination
Avoid discrimination against colleagues or students on the basis of sex, race, ethnicity, or other factors not related to scientific competence and integrity.
Competence
Maintain and improve your own professional competence and expertise through lifelong education and learning; take steps to promote competence in science as a whole.
Legality
Know and obey relevant laws and institutional and governmental policies.
Animal Care
Show proper respect and care for animals when using them in research. Do not conduct unnecessary or poorly designed animal experiments.
Human Subjects Protection
When conducting research on human subjects, minimize harms and risks and maximize benefits; respect human dignity, privacy, and autonomy; take special precautions with vulnerable populations; and strive to distribute the benefits and burdens of research fairly.
* Adapted from Shamoo A and Resnik D. 2015. Responsible Conduct of Research, 3rd ed. (New York: Oxford University Press). https://www.niehs.nih.gov/research/resources/bioethics/whatis/index.cfm

Research often forms the basis of policy decisions and laws. It is vital that research used as the basis of those decisions be conducted as far as possible in a manner free of bias and in accord with ethical research guidelines.

University of Birmingham: Irrigating vegetables with wastewater in African cities may spread disease

13 Oct

The Food and Agriculture Organization wrote in Chapter 2 – Health risks associated with wastewater use:

The survival of pathogens and how they infect a new host needs to be understood in developing a programme to eliminate or minimize health risks. The importance and complexity of the rural health problem for those living and working where wastewater is used is beyond the scope of this document. The focus of this document will be on the concern with those who handle, prepare or eat the crop after it has been harvested. The health issues associated with wastewater use for the handlers, preparers and consumers of the crop can be broken down into a series of questions (each will be covered in more detail in subsequent sections of this document):
What types of pathogens are likely to be present in the wastewater?
How many and what types of pathogens reach the field or crop?
Are these pathogens likely to survive in sufficient numbers and for sufficient time to be infectious to the handler or consumer?
How significant is the infection route for the various pathogens?
Which crops carry the highest potential for carrying infections to the handler or consumer?
Are there guidelines or limits available to measure the potential for health risk?
Types of pathogens present in wastewater
Wastewater or natural water supplies into which wastewater has been discharged, are likely to contain pathogenic organisms similar to those in the original human excreta. Disease prevention programmes have centred upon four groups of pathogens potentially present in such wastes: bacteria, viruses, protozoa and helminths. There have been extensive reviews published on the range of these pathogenic organisms normally found in human excreta and wastewater. The most complete reviews are Feachem et al. (1983), Rose (1986) and Shuval et al. (1986a). The following short discussion is extracted from those reviews and is presented to establish a basic understanding of the pathogens and their abundance.
Bacteria. The faeces of a healthy person contains large numbers of bacteria (> 1010/g), most of which are not pathogenic. Pathogenic or potentially pathogenic bacteria are normally absent from a healthy intestine unless infection occurs. When infection occurs, large numbers of pathogenic bacteria will be passed in the faeces thus allowing the spread of infection to others. Diarrhoea is the most prevalent type of infection, with cholera the worst form. Typhoid, paratyphoid and other Salmonella type diseases are also caused by bacterial pathogens.
Viruses. Numerous viruses may infect humans and are passed in the faeces (> 109/g). Five groups of pathogenic excreted viruses are particularly important: adenoviruses, enteroviruses (including polioviruses), hepatitis A virus, reoviruses and diarrhoea-causing viruses (especially rotavirus).
Protozoa. Many species of protozoa can infect humans and cause diarrhoea and dysentery. Infective forms of these protozoa are often passed as cysts in the faeces and humans are infected when they ingest them. Only three species are considered to be pathogenic: Giardia lamblia, Balantidium coli and Entamoeba histolytica. An asymptomatic carrier state is common in all three and may be responsible for continued transmission.
Helminths. There are many species of parasitic worms or helminths that have human hosts. Some can cause serious illnesses and the ones that pass eggs or larval forms in the excreta are of importance in considering wastewater use. Most helminths do not multiply within the human host, a factor of great importance in understanding their transmission, the ways they cause disease and the effects that environmental change will have on their control. Often the developmental stages (life cycles) through which they pass before reinfecting humans are very complex. Those that have soil, water or plant life as one of their intermediate hosts are extremely important in any scheme where wastewater is used directly or indirectly.
The helminths are classified in two main groups: the roundworms (nematodes) and worms that are flat in cross section. The flatworm, in turn, may be divided into two groups: the tapeworms which form chains of helminths “segments” and the flukes which have a single, flat, unsegmented body. Most of the roundworms that infect humans and also the schistosome flukes have separate sexes. The result is that transmission depends upon infection with both male and female worms and upon meeting, mating and egg production within the human body….
Relative health risk from wastewater use
The discussion in the previous sections show that a broad spectrum of pathogenic microorganisms including bacteria, viruses, helminths and protozoa is present in wastewater and they survive for days, weeks and at times months in the soil and on crops that come in contact with wastewater. Early approaches to measuring the health risk from these pathogenic micro-organisms centred on detection. Based upon the fact that these micro-organisms could survive, detection in any of these environments was sufficient to indicate that a public health problem existed. It was then assumed that such detection showed evidence that a real potential for disease transmission existed (Shuval et al., 1986a; Shuval, 1991). This is a “zero-risk” approach. Throughout the years a number of standards and guidelines have been developed on this zero-risk approach. This led to standards for wastewater use that approached those of drinking water especially where vegetable crops were being grown…. http://www.fao.org/docrep/w5367e/w5367e04.htm

A University of Birmingham study questions the use of waste water in certain circumstances for use in agriculture.

Science Daily reported in Irrigating vegetables with wastewater in African cities may spread disease:

Urban farmers growing vegetables to feed millions of people in Africa’s ever-growing cities could unwittingly be helping to spread disease by irrigating crops with wastewater, a new study reveals.
Experts discovered that wastewater collected from canals used for urban agriculture in Burkina Faso was rich in virulent human pathogens which cause gastroenteritis and diarrhea — a major cause of death in low and middle-income countries.
Researchers at the University of Birmingham led an international team from Burkina Faso, Cameroon and Germany in studying wastewater samples from three canals in the capital Ouagadougou — a city of 2.2 million inhabitants.
After identifying a wide range of antibiotic resistance genes in the water, they concluded that using wastewater for urban agriculture in the city posed a high risk of spreading bacteria and antimicrobial resistance among humans and animals.
With the urban population in sub-Saharan Africa expected to rise from 400 million (2010) to 1.26 billion in 2050, according to UN estimates, agriculture in towns and cities is recognised as a vital way of contributing to food security and alleviating poverty….
Dr Blaise Bougnon from the University of Yaounde (Cameroon), commented: “Some 200 million urban dwellers are reported to be engaged in urban agriculture world-wide and, in some cases, produce up to 90 per cent of cities’ demand for perishable vegetables, according to UN research.
“Over 80 per cent of domestic and industrial wastewater generated in low and middle-income countries is discharged untreated into the environment. Because of its low cost, availability and nutrient content, urban agriculture relies on wastewater for irrigation.”
There is an increasing number of bacteria that are multi-resistant against common antibiotics and cannot be treated by current therapies. Antibiotic resistance has led to the need for more expensive drugs, which many cannot afford, resulting in increased morbidity and mortality.
Between 50 and 90 per cent of antibiotics administered to humans and animals are excreted as a mixture of parent drug and metabolite forms, with significant levels of active drug ending up in the environment, where they may persist in soil and aquatic ecosystems.
The study found evidence in the canal water samples of pathogens commonly responsible for waterborne diseases which could lead to people directly or indirectly exposed to these wastewaters suffering from acute diarrhea, chronic gastritis, and gastroenteritis.
In low and middle-income countries 842,000 people die annually from diarrhea, according to the World Health Organisation, because of inadequate water, sanitation, and hygiene. https://www.sciencedaily.com/releases/2018/10/181012102225.htm

Professor Laura Piddock, from the University of Birmingham’s Institute of Microbiology and Infection, commented: “Using wastewater for agricultural irrigation represents a very serious health risk, not least as it increases exposure to faecal pathogens. Wastewater appears to be a ‘hot spot’ for antibiotic resistant bacteria in Burkina Faso.”
“We urgently need further investigations to determine the extent that exposed populations are affected by this health issue. There is also an urgent need to improve global access to clean water, sanitation, and hygiene in low and middle-income countries to help prevent bacterial resistance spreading from the environment to people.”

The International Water Management (IWMI) Institute researches water issues.

The IWMI listed crucial research issues in the safe use of waste water in agriculture:

Studies in Pakistan, Ghana, Vietnam and Mexico have examined both the positive and negative impacts of wastewater reuse for agriculture. Current IWMI work on wastewater can be found here http://www.iwmi.cgiar.org/publications/briefs/wle-towards-sustainable-intensification-briefs/
Key research questions
• What are the dangers of uncontrolled wastewater irrigation in terms of public health and pollution?
• How can the nutrient value of wastewater be assessed?
• What sustainable practices are being used that can be transferred to benefit poor rural areas in other countries?
• From a public health perspective, which crops are the best candidates for wastewater irrigation and which should be avoided? http://www.iwmi.cgiar.org/issues/water-and-health/wastewater-use-for-agriculture/
The Water Project researches issues related to water supply and sustainabliy.
According to the Water Project’s article, Facts about Water: Statistics of the Water Crisis:
783 million people do not have access to clean and safe water worldwide. 2
319 million people in Sub-Saharan Africa are without access to improved reliable drinking water sources 16                                                                                                              Sub-Saharan Africa is among the regions with the greatest drinking water spending needs, with the greatest investment needs in rural areas. 17
Two thirds or about 102 million of the 159 million people still using surface water live in Sub-Saharan Africa 14
1 in 9 people world wide do not have access to safe and clean drinking water. 13
443 million school days are lost each year due to water-related diseases. 4
In developing countries, as much as 80% of illnesses are linked to poor water and sanitation conditions. 5
1 in 3 people, or 2.4 billion, are without improved sanitation facilities. 14
695 million of a global 2.4 billion people living without improved sanitation facilities live in Sub-Saharan Africa. 16
Exposure to unsafe drinking water, inadequate sanitation and poor hygiene is a leading cause of cholera and a variety of infectious and tropical diseases in the African Region. 15
Half of the world’s hospital beds are filled with people suffering from a water-related disease. 8
Of Sub-Saharan healthcare facilities, 42% lack an improved water source within 500m, 16% lack improved sanitation, and 36% lack soap for hand washing. 14
Girls under the age of 15 are twice as likely as boys to be the family member responsible for fetching water. 2
The physical and time burden of water hauling was found to fall primarily on women and girls who make up 72% of those tasked with fetching water. 14
Women and girls are responsible for water collection in seven out of ten households in 45 developing countries. 14
Over half of the developing world’s primary schools don’t have access to water and sanitation facilities. Without toilets, girls often drop out at puberty. 3
Less than one in three people in Sub-Saharan Africa have access to a proper toilet. 2
In Sub-Saharan Africa, in the 38 countries for which data is available, hand washing prevalence is at best 50%. 16
84% of the people who don’t have access to improved water, live in rural areas, where they live principally through subsistence agriculture. 2                                                              The average container for water collection in Africa, the jerry can, weighs over 40 lbs when full. 9
Almost two-thirds, 64% of households rely on women to get the family’s water when there is no water source in the home. 2
Globally we use 70% of our water sources for agriculture and irrigation, and only 10% on domestic uses. 1
Nearly 1 out of every 5 deaths under the age of 5 worldwide is due to a water-related disease. 6
According to the World Health Organization, for every $1 invested in water and sanitation, there is an economic return of between $3 and $34! 12
By investing in clean water alone, young children around the world can gain more than 413 million days of health! 7
The United Nations estimates that Sub-Saharan Africa alone loses 40 billion hours per year collecting water; the same as an entire year’s labor in all of France! 10
Research has shown that for every 10% increase in women’s literacy, a country’s whole economy can grow by up to 0.3%. 11

Harvard study: Large-scale US wind power would cause warming that would take roughly a century to offset

11 Oct

Argonne National Laboratory described wind power in Wind Energy Basics:

Basic information on wind energy and wind power technology, resources, and issues of concern.
Wind Energy and Wind Power
Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth’s surface, and rotation of the earth. Wind flow patterns are modified by the earth’s terrain, bodies of water, and vegetative cover. This wind flow, or motion energy, when “harvested” by modern wind turbines, can be used to generate electricity.
How Wind Power Is Generated
The terms “wind energy” or “wind power” describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like.
Wind Turbines
Wind turbines, like aircraft propeller blades, turn in the moving air and power an electric generator that supplies an electric current. Simply stated, a wind turbine is the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.
Wind Turbine Types
Modern wind turbines fall into two basic groups; the horizontal-axis variety, like the traditional farm windmills used for pumping water, and the vertical-axis design, like the eggbeater-style Darrieus model, named after its French inventor. Most large modern wind turbines are horizontal-axis turbines.
Turbine Components
Horizontal turbine components include:
• blade or rotor, which converts the energy in the wind to rotational shaft energy;
• a drive train, usually including a gearbox and a generator;
• a tower that supports the rotor and drive train; and
• other equipment, including controls, electrical cables, ground support equipment, and interconnection equipment.
Turbine Configurations
Wind turbines are often grouped together into a single wind power plant, also known as a wind farm, and generate bulk electrical power. Electricity from these turbines is fed into a utility grid and distributed to customers, just as with conventional power plants.
See Wind Energy Photos page for wind farm photographs.
Wind Turbine Size and Power Ratings
Wind turbines are available in a variety of sizes, and therefore power ratings. The largest machine has blades that span more than the length of a football field, stands 20 building stories high, and produces enough electricity to power 1,400 homes. A small home-sized wind machine has rotors between 8 and 25 feet in diameter and stands upwards of 30 feet and can supply the power needs of an all-electric home or small business. Utility-scale turbines range in size from 50 to 750 kilowatts. Single small turbines, below 50 kilowatts, are used for homes, telecommunications dishes, or water pumping.
See Wind Energy Photos page for wind turbine photographs.
Wind Energy Resources in the United States
Wind energy is very abundant in many parts of the United States. Wind resources are characterized by wind-power density classes, ranging from class 1 (the lowest) to class 7 (the highest). Good wind resources (e.g., class 3 and above, which have an average annual wind speed of at least 13 miles per hour) are found in many locations (see United States Wind Energy Resource Map). Wind speed is a critical feature of wind resources, because the energy in wind is proportional to the cube of the wind speed. In other words, a stronger wind means a lot more power. http://windeis.anl.gov/guide/basics/

Harvard Researchers found wind power could cause warming.

Science Daily reported in Large-scale US wind power would cause warming that would take roughly a century to offset:

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. Research publishing in the journal Joule on October 4 reports the most accurate modelling yet of how increasing wind power would affect climate, finding that large-scale wind power generation would warm the Continental United States 0.24 degrees Celsius because wind turbines redistribute heat in the atmosphere.
“Wind beats coal by any environmental measure, but that doesn’t mean that its impacts are negligible,” says senior author David Keith, an engineering and public policy professor at Harvard University. “We must quickly transition away from fossil fuels to stop carbon emissions. In doing so, we must make choices between various low-carbon technologies, all of which have some social and environmental impacts.”
“Wind turbines generate electricity but also alter the atmospheric flow,” says first author Lee Miller. “Those effects redistribute heat and moisture in the atmosphere, which impacts climate. We attempted to model these effects on a continental scale.”
To compare the impacts of wind and solar, Keith and Miller started by establishing a baseline for the 2012-2014 US climate using a standard weather forecasting model. Then they added in the effect on the atmosphere of covering one third of the Continental US with enough wind turbines to meet present-day US electricity demand. This is a relevant scenario if wind power plays a major role in decarbonizing the energy system in the latter half of this century. This scenario would warm the surface temperature of the Continental US by 0.24 degrees Celsius.
Their analysis focused on the comparison of climate impacts and benefits. They found that it would take about a century to offset that effect with wind-related reductions in greenhouse gas concentrations. This timescale was roughly independent of the specific choice of total wind power generation in their scenarios….
More than ten previous studies have now observed local warming caused by US wind farms. Keith and Miller compared their simulated warming to observations and found rough consistency between the observations and model.
They also compared wind power’s impacts with previous projections of solar power’s influence on the climate. They found that, for the same energy generation rate, solar power’s impacts would be about 10 times smaller than wind. But both sources of energy have their pros and cons.
“In terms of temperature difference per unit of energy generation, solar power has about 10 times less impact than wind,” says Miller. “But there are other considerations. For example, solar farms are dense, whereas the land between wind turbines can be co-utilized for agriculture.” The density of wind turbines and the time of day during which they operate can also influence the climatic impacts.
Keith and Miller’s simulations do not consider any impacts on global-scale meteorology, so it remains somewhat uncertain how such a deployment of wind power may affect the climate in other countries….
Keith and Miller also have a related paper, “Observation-based solar and wind power capacity factors and power densities,” being published in Environmental Research Letters on October 4, which validates the generation rates per unit area simulated here using observations. https://www.sciencedaily.com/releases/2018/10/181004112553.htm

Highlights
• Wind power reduces emissions while causing climatic impacts such as warmer temperatures
• Warming effect strongest at night when temperatures increase with height
• Nighttime warming effect observed at 28 operational US wind farms
• Wind’s warming can exceed avoided warming from reduced emissions for a century
Context & Scale
Wind power can impact the climate by altering the atmospheric boundary layer, with at least 40 papers and 10 observational studies now linking wind power to climatic impacts. We make the first comparison between the climatic impacts of large-scale wind power and site-scale observations, finding agreement that warming from wind turbines is largest at night. Wind power’s climatic impacts will continue to expand as more are installed.
Do these impacts matter? How do these impacts compare to the climate benefits of reducing emissions? We offer policy-relevant comparisons: wind’s climatic impacts are about 10 times larger than solar photovoltaic systems per unit energy generated. We explore the temporal trade-off between wind’s climatic impacts and the climate benefits it brings by reducing emissions as it displaces fossil fuels. Quantitative comparisons between low-carbon energy sources should inform energy choices in the transition to a carbon-free energy system.
Summary
We find that generating today’s US electricity demand (0.5 TWe) with wind power would warm Continental US surface temperatures by 0.24°C. Warming arises, in part, from turbines redistributing heat by mixing the boundary layer. Modeled diurnal and seasonal temperature differences are roughly consistent with recent observations of warming at wind farms, reflecting a coherent mechanistic understanding for how wind turbines alter climate. The warming effect is: small compared with projections of 21st century warming, approximately equivalent to the reduced warming achieved by decarbonizing global electricity generation, and large compared with the reduced warming achieved by decarbonizing US electricity with wind. For the same generation rate, the climatic impacts from solar photovoltaic systems are about ten times smaller than wind systems. Wind’s overall environmental impacts are surely less than fossil energy. Yet, as the energy system is decarbonized, decisions between wind and solar should be informed by estimates of their climate impacts. https://www.sciencedirect.com/science/article/pii/S254243511830446X

As with various energy sources there are pros and cons.

Energy.Gov lists the pros and cons of wind energy:

Advantages of Wind Power
• Wind power is cost-effective. Land-based utility-scale wind is one of the lowest-priced energy sources available today, costing between two and six cents per kilowatt-hour, depending on the wind resource and the particular project’s financing. Because the electricity from wind farms is sold at a fixed price over a long period of time (e.g. 20+ years) and its fuel is free, wind energy mitigates the price uncertainty that fuel costs add to traditional sources of energy.
• Wind creates jobs. The U.S. wind sector employed more than 100,000 workers in 2016, and wind turbine technician is one of the fastest-growing American jobs of the decade. According to the Wind Vision Report, wind has the potential to support more than 600,000 jobs in manufacturing, installation, maintenance, and supporting services by 2050.
• Wind enables U.S. industry growth and U.S. competitiveness. Wind has an annual economic impact of about $20 billion on the U.S. economy, The United States has a vast domestic resources and a highly-skilled workforce, and can compete globally in the clean energy economy.
• It’s a clean fuel source. Wind energy doesn’t pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas, which emit particulate matter, nitrogen oxides, and sulfur dioxide—causing human health problems and economic damages. Wind turbines don’t produce atmospheric emissions that cause acid rain, smog, or greenhouse gases.
• Wind is a domestic source of energy. The nation’s wind supply is abundant and inexhaustible. Over the past 10 years, cumulative wind power capacity in the United States increased an average of 30% per year, and wind now has the largest renewable generation capacity of all renewables in the United States.
• It’s sustainable. Wind is actually a form of solar energy. Winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth’s surface irregularities. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid.
• Wind turbines can be built on existing farms or ranches. This greatly benefits the economy in rural areas, where most of the best wind sites are found. Farmers and ranchers can continue to work the land because the wind turbines use only a fraction of the land. Wind power plant owners make rent payments to the farmer or rancher for the use of the land, providing landowners with additional income.
CHALLENGES OF WIND POWER
• Wind power must still compete with conventional generation sources on a cost basis. Depending on how energetic a wind site is, the wind farm might not be cost competitive. Even though the cost of wind power has decreased dramatically in the past 10 years, the technology requires a higher initial investment than fossil-fueled generators.
• Good wind sites are often located in remote locations, far from cities where the electricity is needed. Transmission lines must be built to bring the electricity from the wind farm to the city. However, building just a few already-proposed transmission lines could significantly reduce the costs of expanding wind energy.
• Wind resource development might not be the most profitable use of the land. Land suitable for wind-turbine installation must compete with alternative uses for the land, which might be more highly valued than electricity generation.
• Turbines might cause noise and aesthetic pollution. Although wind power plants have relatively little impact on the environment compared to conventional power plants, concern exists over the noise produced by the turbine blades and visual impacts to the landscape.
• Turbine blades could damage local wildlife. Birds have been killed by flying into spinning turbine blades. Most of these problems have been resolved or greatly reduced through technological development or by properly siting wind plants. https://www.energy.gov/eere/wind/advantages-and-challenges-wind-energy
