Harvard study: Strict ID Laws Don’t Stop Voters: Evidence from a U.S. Nationwide Panel, 2008–2016

14 Feb

Hans A. von Spakovsky and Benjamin Janacek wrote in the National Review article, No, Hillary, Voter-ID Laws Don’t ‘Suppress’ Turnout:

In fact, turnout data from 2012 and 2016 do not show any “voter suppression” because of ID requirements. Nine of the eleven states that have implemented so-called strict ID Laws either saw an increase in turnout or exceeded the national average in turnout in 2016. Two of them, Wisconsin and New Hampshire, finished in the top five nationally. Meanwhile only two of the 17 states plus Washington, D.C., that have no ID requirement finished among the top five.
In short, there is no credible evidence that voter-ID laws have impeded turnout, especially among minorities and Democrats, as their opponents suggest.
The debunked Wisconsin study is, unfortunately, not alone in misusing the data for political gain. A January 2017 study by three professors from the University of California San Diego and Bucknell University — frequently referenced in liberal media outlets — is another unfortunate example. The study erroneously claims that voter-ID laws have a disparate impact on minorities and “diminish the participation of Democrats and those on the left, while doing little to deter the vote of Republicans and those on the right.” This sensational finding generated a media storm, with the help of several opinion pieces from the authors making the politically charged (and false) claim that voter-ID laws “lower minority turnout and benefit the Republican Party.”
But these claims, too, were recently debunked by a group of professors from Yale, Stanford, and the University of Pennsylvania. Upon examining the data in the original study, the group found “no definitive relationship between strict voter ID laws and turnout.” It also found that the original study contained measurement errors, omitted-variable bias, and misinterpreted data.
In reality, then, such studies are designed to obscure the truth. The Heritage Foundation has published numerous papers looking at turnout data in states that implemented voter-ID laws. All of those studies show that ID requirements do not keep voters from the polls, and that some states have even seen increases in turnout after their ID laws went into effect. A University of Missouri study found that Indiana’s turnout increased 2 percent after its voter-ID law was implemented, with no negative impact on minority voters in particular, and increased turnout for Democrats as a whole. Yet another study, this one by the University of Delaware and the University of Nebraska-Lincoln, found that at both the aggregate and individual levels, voter-ID laws did not affect turnout across racial, ethnic, or socioeconomic lines during the 2000, 2002, 2004, and 2006 elections.
In short, there is no credible evidence that voter-ID laws have impeded turnout, especially among minorities and Democrats, as their opponents suggest. Meanwhile, a Heritage Foundation database tracking documented voter fraud now contains 492 cases and 773 criminal convictions, with untold other cases unreported and unprosecuted…. https://www.nationalreview.com/2017/06/hillary-clinton-wisconsin-voter-suppression-claim-dubious-excuse-flawed-campaign/

Voter ID requirements are intended to reduce voter fraud. See, Is Voter Fraud Real? A look at California’s illegal voter-registration problem https://www.theepochtimes.com/is-voter-fraud-real_2704461.html

Guy Benson wrote in the Town Hall article, ‘Suppression,’ Debunked: Study Concludes Voter ID Laws Do Not Depress Voter Turnout:

One pillar of dogma among leftist activists is that voter ID laws, under which citizens are required to present a valid form of identification in order to cast ballots in elections, amount to insidious and racist forms of “voter suppression.” That term deserves to be placed in scare quotes because it’s often employed as a catch-all phrase to describe any policy or idea that liberals believe would reduce their chances of winning. Voter ID laws have been upheld by the Supreme Court as constitutional, and enjoy overwhelming public support — including approval from large majorities of racial minorities, who evidently don’t share the professional Left’s racialized hysteria. We’ve written previously about how, if reducing turnout among certain populations truly were the goal of such laws, they’ve failed miserably. This example out of Georgia comes to mind:
When Georgia became one of the first states in the nation to demand a photo ID at the ballot box, both sides served up dire predictions. Opponents labeled it a Jim Crow-era tactic that would suppress the minority vote…Turnout among black and Hispanic voters increased from 2006 to 2010, dramatically outpacing population growth for those groups over the same period…“I think the rhetoric on both sides has been overstated,” said Edward Foley, executive director of an election law center at The Ohio State University’s Moritz College of Law. “It hasn’t had the voter-suppressing effect that some people feared,” Foley said.
Far more useful details are available here. Speaking of Georgia and alleged voter suppression, and given the recently-raised profile of that state’s failed 2018 gubernatorial nominee….. A new academic study reviewed the data and reached important conclusions:
Strict voter ID laws do not suppress turnout, a new paper finds, regardless of sex, race, Hispanic identity, or party affiliation…In total, 10 states, ranging from Georgia to Wisconsin, require voters to show ID in order to vote. Seven of those states require a photo ID, and three do not. An additional 25 states “request” that voters display ID, but may still permit them to vote on a provision ballot if they cannot. The remaining states “use other methods to verify the identity of voters,” according to the National Conference of State Legislatures. The new research, from an economics professor at the University of Bologna and another at Harvard Business School, indicates that “strict” voting laws of the type implemented in those ten states do not have a statistically significant effect on voter turnout…”Strict ID laws have no significant negative effect on registration or turnout, overall or for any subgroup defined by age, gender, race, or party affiliation,” the paper’s authors found. “Most importantly,” they write, strict ID laws “do not decrease the participation of ethnic minorities relative to whites. The laws’ overall effects remain close to zero and non-significant whether the election is a midterm or presidential election, and whether the laws are the more restrictive type that stipulate photo IDs.”
Confirmed: The top talking point against Voter ID laws is bogus…. https://townhall.com/tipsheet/guybenson/2019/02/13/suppression-debunked-study-concludes-voter-id-laws-dont-decrease-voter-turnout-n2541344

Abstract
U.S. states increasingly require identification to vote – an ostensive attempt to deter fraud that prompts complaints of selective disenfranchisement. Using a difference-in-differences design on a 1.3-billion-observations panel, we find the laws have no negative effect on registration or turnout, overall or for any group defined by race, gender, age, or party affiliation. These results hold through a large number of specifications and cannot be attributed to mobilization against the laws, measured by campaign contributions and self-reported political engagement. ID requirements have no effect on fraud either – actual or perceived. Efforts to improve elections may be better directed at other reforms.

Hans A. Von Spakovsky wrote in the U.S. News article, Voter ID Laws Protect the Integrity of Our Democracy:

Opponents are wrong that voter ID will depress turnout or prevent large number of individuals from voting. ID laws have been in place in Georgia and Indiana for more than five years, and there has been no decrease in the turnout of minority, poor, and elderly voters. That is because Americans of every background overwhelmingly have photo ID. And the few who do not can easily obtain a free one in the states that have implemented such laws.
Americans have to use photo ID constantly in everyday life—to drive a car, board a plane, buy a beer, check into a hotel, get into many government buildings, or see a doctor. They even need one to get into the Justice Department in Washington where Eric Holder is unjustly and unfairly fighting election integrity by trying to stop voter ID laws.
Voter ID is a perfectly reasonable and easily met requirement that protects the integrity of our democracy. That is why the American people support it….. https://www.usnews.com/debate-club/should-photo-id-be-required-to-vote/voter-id-laws-protect-the-integrity-of-our-democracy

For those who lie, yes lie and say VOTER INTEGRITY is RACIST, Mexico is among many countries who require ID. Both Mexico and India have Voter ID.

Gary Maher wrote in Mexico and India Have Voter ID But Democrats Think Blacks Are Too Stupid to Get ID:

Our ruling:
Miller said: “To vote in Mexico every eligible Mexican citizen has to have a tamper-proof photo-ID card with a thumbprint and an embossed hologram.”
But not the United States of America.
Democrats think blacks are too stupid to get an ID card and they want illegals voting so the party opposes voter ID.
But they’re not racists.
Mexico has required secure photo IDs at the polls for nearly 20 years. We rate the statement True…. https://www.usapoliticstoday.org/mexico-india-voter-photo-id/

Without Voter Integrity, AMERICAN CITIZENS are robbed of the RULE OF LAW!

Nobody will ever deprive the American people of the right to vote except the American people themselves and the only way they could do this is by not voting.
Franklin D. Roosevelt

THE KEY POINT IS VOTING IS A RIGHT OF AMERICAN CITIZENS, PERIOD.

University of Texas Medical Branch at Galveston study: Mental illness not to blame for gun violence, study finds

10 Feb

Here’s today’s COMMENT FROM AN OLD FART: The U.S. Constitution is a bit like the Bible. People want to select passage from both documents which suit their purpose and their intent. People don’t want to deal with the parts that they don’t agree with or that they find disagreeable.

Political party culture is stuck on stupid. Moi grew up in Pierce County and was for many years a dem in the mold of Senators Henry M. Jackson and Warren G. Magnuson. There is no room in today’s dem party for folks like moi. Moi doesn’t believe in abortion in all circumstances and supports the FIRST AMENDMENT guarantees. In light of the fact that moi is an independent, this story illustrates why moi is an independent. Every now and again is a story that is so stupid, one has to comment.

City Looks to Twitter for Answer to Gun Problem: The best submitted ideas will be debated at an Oct. 11 panel discussion:

The City of Chicago is asking residents with ideas on how to get illegal guns off the streets to share their thoughts — in 140 characters or fewer on Twitter.
The initiative is part of Chicago Ideas Week, an annual forum for innovators, artists, scientists and others to share ideas and inspire action.
Those who think they know how to cut off the flow of illegal guns into Chicago are being asked to tweet them with the hashtag (hash)whatifchicago.
The best submitted ideas will be debated at an Oct. 11 panel discussion.
Chicago’s social media director, Kevin Hauswirth, says the effort is a great example of “the potential power that social media offers city government.” http://www.nbcchicago.com/news/local/City-Looks-to-Twitter-for-Answer-to-Gun-Problem-171939501.html#ixzz27ziNIsVD

Really, no one in Chicago can guess how to reduce gun violence. Must be that stranglehold of P.C. And ideology.

Let moi makes some suggestions even though she lives in Seattle not Chicago. Seattleites shouldn’t gloat as our government is equally stuck on stupid with a tendency to stick their head in sand regarding Seattle’s own gang problem.

Part if the solution will not be P.C. for “progressives.” In the short-term, just about any crime-ridden neighborhood in America needs better education and economic development. Can one say, JOBS, JOBS, and MORE JOBS. In the longer term, there will have to be a change in the cultural dynamic and thinking of groups trapped by low-income culture and mentality. This is what moi said in UN-traditional Father’s Day message: Don’t become a father unless you can make the commitment to YOUR child:
Humans have free will and are allowed to choose how they want to live. What you do not have the right to do is to inflict your lifestyle on a child. So, the responsible thing for you to do is go to Planned Parenthood or some other outlet and get birth control for yourself and the society which will have to live with your poor choices. Many religious folks are shocked because I am mentioning birth control, but most sluts have few religious inklings or they wouldn’t be sluts. A better option for both sexes, if this lifestyle is a permanent option, is permanent birth control to lessen a contraception failure. People absolutely have the right to choose their particular lifestyle. You simply have no right to bring a child into your mess of a life. I observe people all the time and I have yet to observe a really happy slut. Seems that the lifestyle is devoid of true emotional connection and is empty. If you do find yourself pregnant, please consider adoption.

Let’s continue the discussion. Some folks may be great friends, homies, girlfriends, and dudes, but they make lousy parents. Could be they are at a point in their life where they are too selfish to think of anyone other than themselves, they could be busy with school, work, or whatever. No matter the reason, they are not ready and should not be parents. Birth control methods are not 100% effective, but the available options are 100% ineffective in people who are sexually active and not using birth control. So, if you are sexually active and you have not paid a visit to Planned Parenthood or some other agency, then you are not only irresponsible, you are Eeeevil. Why do I say that, you are playing Russian Roulette with the life of another human being, the child. You should not ever put yourself in the position of bringing a child into the world that you are unprepared to parent, emotionally, financially, and with a commitment of time. So, if you find yourself in a what do I do moment and are pregnant, you should consider adoption. This is a totally NOT P.C. Message because “progressives” want to think that government can solve this society’s problem. First Lady Michelle Obama is a gracious and classy woman, but really girlfriend, the problem is too many “baby mamas” and “baby daddy.” When we have around 70% of Black children born to woman who are most likely not able to feed and care for the children, whether they are eating vegetables is not as relevant. One needs to treat the gaping head wound first.

There must be cultural change in addition to economic development and “progressives” don’t want to touch that hot potato. Meanwhile, because this society is not dealing with the root problem, the carnage goes on.
A University of Texas study examined gun violence and mental illness.

Science Daily reported in Mental illness not to blame for gun violence:

Counter to a lot of public opinion, having a mental illness does not necessarily make a person more likely to commit gun violence. According to a new study, a better indicator of gun violence was access to firearms.
A study by researchers at The University of Texas Medical Branch at Galveston looked into the association between gun violence and mental health in a group of 663 young adults in Texas. Their results were published in the journal Preventive Medicine.
“Counter to public beliefs, the majority of mental health symptoms examined were not related to gun violence,” said Dr. Yu Lu, a postdoctoral research fellow at UTMB and the lead author of the study.
What researchers found instead was that individuals who had gun access were approximately 18 times more likely to have threatened someone with a gun. Individuals with high hostility were about 3.5 times more likely to threaten someone.
“These findings have important implications for gun control policy efforts,” Lu said.
Each year, an estimated 75,000 to 100,000 Americans are injured by firearms and 30,000 to 40,000 die from firearms, according to the Centers for Disease Control.
“Much of the limited research on gun violence and mental illness has focused on violence among individuals with severe mental illnesses or rates of mental illness among individuals arrested for violent crimes,” Lu said. “What we found is that the link between mental illness and gun violence is not there.”
Lu and Dr. Jeff Temple, another author of the study and a professor at UTMB, surveyed participants in a long-term study about their firearm possession and use as well as about anxiety, depression, stress, posttraumatic stress disorder, hostility, impulsivity, borderline personality disorder, mental health treatment and other demographic details.
The researchers found that individuals who had access to guns, compared to those with no such access, were over 18 times more likely to have threatened someone with a gun, even after controlling for a number of demographic and mental health variables. Meanwhile, most mental health symptoms were unrelated to gun violence.
“Taking all this information together, limiting access to guns, regardless of any other mental health status, demographics or prior mental health treatments, is the key to reducing gun violence,” Temple said…. https://www.sciencedaily.com/releases/2019/02/190207102607.htm

GALVESTON, Texas – Counter to a lot of public opinion, having a mental illness does not necessarily make a person more likely to commit gun violence. According to a new study, a better indicator of gun violence was access to firearms.

What both proponents of gun control and those who advocate unfettered gun possession along with unlimited possession of ALL types of guns don’t want to acknowledge is that it ultimately goes back to the Constitutional process of a legislature enacting a law and the judiciary reviewing the Constitutionality of the law. Neither side may be happy with the result. See, Both sides in the gun debate are acting like morons https://drwilda.com/tag/gun-control/

Virginia Tech study: First study to find digital ads work — on millennials

3 Feb

Moi wrote in Social media addiction:

Moi wonders if anyone is surprised by this development. The UK’s Daily Mail reported about internet addiction among the young in Internet Rehab Clinic for ‘Sreenager” Children Hooked on modern technology https://www.dailymail.co.uk/news/article-1258703/Internet-rehab-clinic-screenager-children-hooked-modern-technology.html In a 2010 Movieline interview, Miley gives the reason for closing her Twitter account at that time. According to Miley, It’s Dangerous, It Wastes Your Life, It’s Not Fun http://www.mtv.com/news/1634000/miley-cyrus-says-the-internet-wastes-your-life/ Ya, think?

“I was kind of, like, tired of telling everyone what I’m doing,” Cyrus told Movieline. “I hate when I read things and celebrities are complaining like, ‘I have no personal life.’ I’m like, well that’s because you write everything that you’re doing.”
“So I was that person who was like, ‘I’m so sad. I have no real, normal life, everyone knows what I’m doing.’ And I’m like, well that’s my own fault because I’m telling everyone,” Cyrus said. “And then I’d tweet, ‘I’m here,’ and I’d wonder why a thousand fans are outside the restaurant. Well, hello, I just told them. So I’m just, like, kind of thinking doesn’t really make a lot of sense. Everything I’m saying is not really going with what I’m putting on the internet.
Asked if the change has been for the better, Cyrus took a moment to consider, then said, “I’m a lot less on my phone, I’m a little bit more social. I have a lot more real friends as opposed to friends who are on the internet who I’m talking to — which is like not cool, not safe, not fun and most likely not real. I think everything is just better when you’re not so wrapped up in [the internet].”

What Miley was saying is that she wants the type of social relationships which come from face-to-face contact. In other words, she wants healthier social interactions. https://drwilda.com/2011/11/24/social-media-addiction     Since 2010, social media has become the primary method of reaching a certain segment of the population.

Science Daily reported in First study to find digital ads work — on millennials:

While millions of dollars are spent every day on digital advertising, no research has found these ads actually work — until now.
Katherine Haenschen, assistant professor in the department of communication at Virginia Tech said “this is first time we found that digital ads do something and what they do is they increase voter turnout among millennials in municipal elections.”
According to research published in Political Communication digital ads increased voter participation in a Dallas municipal election.
Why Dallas? Less than 7 percent of residents, and under 2 percent of millennials voted in their 2015 municipal election, making it the worst major city in the United States for voter turnout.
Discouraged by that statistic civic leaders wanted change. The effort led to a collaboration with the Dallas Morning News, Jay Jennings of University of Texas, and of course Haenschen.
In the study, millennials were exposed to two or four weeks of ads in the month leading up to the election. One set of ads focused on providing information about city council and school board candidates published by Dallas Morning News. The other set of ads served as election participation reminders. Some groups were exposed to both sets of ads (information and reminders) while other groups only saw one set of ads. At most, people saw ads four times per day.
“Since many adults encounter over 2,000 ads a day,” we gave people a very small amount of ads and were still able to change their behavior,” Haenschen said.
In competitive districts, when millennials were exposed to all four weeks of ads, voter turnout went up. In non-competitive districts the effect was the opposite, suggesting users in uncontested districts may have chosen not to participate.
One of the more surprising findings was the effect the digital ads had on millennials who “are a notoriously difficult demographic to reach,” said Haenschen. “They don’t have landlines and move around a lot making them difficult targets for candidates.”
That is why Haenschen and collaborators chose to use cookie-targeted digital ads for the study. “Millennials’ IP address is perhaps more stable than their physical address,” said Haenschen…. https://www.sciencedaily.com/releases/2019/01/190130133029.htm

But the thing that excites Haenschen the most about this research was it showed a path to mobilize people who had never voted in an election.
“One thing that I think is so great about our study is that it was able to mobilize people who had never voted in a municipal election before,” said Haenschen. “So you figure now these folks have been mobilized to vote for their city council member and school board one time. Now they will be on lists of people who voted in prior municipal elections, so future candidates will reach out to them. We can hope that it may have snowball effect over time, and this can be a way to systematically increase turnout among a tough demographic.”

There is something to be said for Cafe Society where people actually meet face-to-face for conversation or the custom of families eating at least one meal together. Time has a good article on The Magic of the Family Meal http://content.time.com/time/magazine/article/0,9171,1200760,00.html See, also The Importance of Eating Together: Family dinners build relationships, and help kids do better in school. https://www.theatlantic.com/health/archive/2014/07/the-importance-of-eating-together/374256/

It also looks like Internet rehab will have a steady supply of customers according to an article reprinted in the Seattle Times by Hillary Stout of the New York Times. In Toddlers Latch On to iPhones – and Won’t Let Go https://www.seattletimes.com/life/lifestyle/toddlers-latch-onto-iphones-8212-and-wont-let-go/ Stout reports:

But just as adults have a hard time putting down their iPhones, so the device is now the Toy of Choice — akin to a treasured stuffed animal — for many 1-, 2- and 3-year-olds. It’s a phenomenon that is attracting the attention and concern of some childhood development specialists.

Looks like social networking may not be all that social.

University of California Berkeley study: New 3D printer shapes objects with rays of light: The technology has potential to transform how products from prosthetics to eyeglass lenses are designed and manufactured

2 Feb

3D Printer.com describes what a 3D printer is:

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.
The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine.
3D printing enables you to produce complex (functional) shapes using less material than traditional manufacturing methods….
How Does 3D Printing Work?
It all starts with the creation of a 3D model in your computer. This digital design is for instance a CAD (Computer Aided Design) file. A 3D model is either created from the ground up with 3D modeling software or based on data generated with a 3D scanner. With a 3D scanner you’re able to create a digital copy of an object…. https://3dprinting.com/what-is-3d-printing/

Alek Hidell of Anonymous posted 3D Printed Guns Make Gun Control Debate Obsolete:

That brings up a whole new debate. If you are able to manufacture banned, hard to get or untraceable guns, the entire existing gun debate becomes irrelevant. Who cares about background checks when you can make your AR at home?
Everyone should have seen this coming. Where there is a will, there is a way. The future of 3D printed guns is uncertain, but the conversation is only just beginning. I’m pretty sure that like all other digital information, once its out there, its out there and cannot be turned back. While politicians go around in circles with the current gun debate in the U.S., innovators like Cody Wilson will be there to show the folly in their ways…. http://anonhq.com/3d-printed-guns-make-gun-control-debate-obsolete/

3D printing is another area where technology will have profound impact on society.

Science Daily reported in New 3D printer shapes objects with rays of light: The technology has potential to transform how products from prosthetics to eyeglass lenses are designed and manufactured:

A new 3D printer uses light to transform gooey liquids into complex solid objects in only a matter of minutes.
Nicknamed the “replicator” by the inventors — after the Star Trek device that can materialize any object on demand — the 3D-printer can create objects that are smoother, more flexible and more complex than what is possible with traditional 3D-printers. It can also encase an already existing object with new materials — for instance, adding a handle to a metal screwdriver shaft — which current printers struggle to do.
The technology has the potential to transform how products from prosthetics to eyeglass lenses are designed and manufactured, the researchers say.
“I think this is a route to being able to mass-customize objects even more, whether they are prosthetics or running shoes,” said Hayden Taylor, assistant professor of mechanical engineering at the University of California, Berkeley, and senior author of a paper describing the printer, which appears online today (Jan. 31) in the journal Science.
“The fact that you could take a metallic component or something from another manufacturing process and add on customizable geometry, I think that may change the way products are designed,” Taylor said.
Most 3D printers, including other light-based techniques, build up 3D objects layer by layer. This leads to a “stair-step” effect along the edges. They also have difficulties creating flexible objects because bendable materials could deform during the printing process, and supports are required to print objects of certain shapes, like arches.
The new printer relies on a viscous liquid that reacts to form a solid when exposed to a certain threshold of light. Projecting carefully crafted patterns of light — essentially “movies” — onto a rotating cylinder of liquid solidifies the desired shape “all at once.”
“Basically, you’ve got an off-the-shelf video projector, which I literally brought in from home, and then you plug it into a laptop and use it to project a series of computed images, while a motor turns a cylinder that has a 3D-printing resin in it,” Taylor said. “Obviously there are a lot of subtleties to it — how you formulate the resin, and, above all, how you compute the images that are going to be projected, but the barrier to creating a very simple version of this tool is not that high.”
Taylor and the team used the printer to create a series of objects, from a tiny model of Rodin’s “The Thinker” statue to a customized jawbone model. Currently, they can make objects up to four inches in diameter.
“This is the first case where we don’t need to build up custom 3D parts layer by layer,” said Brett Kelly, co-first author on the paper who completed the work while a graduate student working jointly at UC Berkeley and Lawrence Livermore National Laboratory. “It makes 3D printing truly three-dimensional….” https://www.sciencedaily.com/releases/2019/01/190131143330.htm

New 3D printer uses rays of light to shape objects, transform product design
By Kara Manke| January 31, 2019
A new 3D printer uses light to transform gooey liquids into complex solid objects in only a matter of minutes.
Nicknamed the “replicator” by the inventors — after the Star Trek device that can materialize any object on demand — the 3D printer can create objects that are smoother, more flexible and more complex than what is possible with traditional 3D printers. It can also encase an already existing object with new materials — for instance, adding a handle to a metal screwdriver shaft — which current printers struggle to do.

“This is the first case where we don’t need to build up custom 3D parts layer by layer,” said Brett Kelly, co-first author on the paper who completed the work while a graduate student working jointly at UC Berkeley and Lawrence Livermore National Laboratory. “It makes 3D printing truly three-dimensional.”
The new printer was inspired by the computed tomography (CT) scans that can help doctors locate tumors and fractures within the body.
CT scans project X-rays or other types of electromagnetic radiation into the body from all different angles. Analyzing the patterns of transmitted energy reveals the geometry of the object.
“Essentially we reversed that principle,” Taylor said. “We are trying to create an object rather than measure an object, but actually a lot of the underlying theory that enables us to do this can be translated from the theory that underlies computed tomography.”
Besides patterning the light, which requires complex calculations to get the exact shapes and intensities right, the other major challenge faced by the researchers was how to formulate a material that stays liquid when exposed to a little bit of light, but reacts to form a solid when exposed to a lot of light.
“The liquid that you don’t want to cure is certainly having rays of light pass through it, so there needs to be a threshold of light exposure for this transition from liquid to solid,” Taylor said.
The 3D printing resin is composed of liquid polymers mixed with photosensitive molecules and dissolved oxygen. Light activates the photosensitive compound which depletes the oxygen. Only in those 3D regions where all the oxygen has been used up do the polymers form the “cross-links” that transform the resin from a liquid to a solid. Unused resin can be recycled by heating it up in an oxygen atmosphere, Taylor said.
“Our technique generates almost no material waste and the uncured material is 100 percent reusable,” said Hossein Heidari, a graduate student in Taylor’s lab at UC Berkeley and co-first author of the work. “This is another advantage that comes with support-free 3D printing.”
The objects also don’t have to be transparent. The researchers printed objects that appear to be opaque using a dye that transmits light at the curing wavelength but absorbs most other wavelengths.
“This is particularly satisfying for me, because it creates a new framework of volumetric or ‘all-at-once’ 3D printing that we have begun to establish over the recent years,” said Maxim Shusteff, a staff engineer at the Livermore lab. “We hope this will open the way for many other researchers to explore this exciting technology area.”
Indrasen Bhattacharya of UC Berkeley is co-first author of the work. Other authors include Christopher M. Spadaccini of Lawrence Livermore National Laboratory.
This work was supported by UC Berkeley faculty startup funds and by Laboratory-Directed Research and Development funds from Lawrence Livermore National Laboratory. The team has filed a patent application on the technique.

If a person is intent on harm, there are a variety of methods. Table 20 of the Uniform Crime Report provides those statistics. http://www.fbi.gov/about-us/cjis/ucr/crime-in-the-u.s/2011/crime-in-the-u.s.-2011/tables/table-20

Guns are not the only instruments of harm.

Evie Blad reported in the Education Week article, School Stabbings Signal Need for Broad Safety Plans: Experts question hyperfocus on guns:

Large-scale shootings have been a dominant driver of school safety debates, but a stabbing spree at a Pennsylvania high school this month should serve as a reminder that educators need to be prepared for a range of situations—including smaller, nonfatal incidents that don’t involve guns at all, school safety experts say.
Following most school shootings—like the December 2012 killings at Sandy Hook Elementary School in Newtown, Conn.—conversation quickly turns to the polarizing subject of gun policy.
And while some districts work to implement comprehensive safety plans that address mental-health concerns, school climate, and security procedures, policymakers often direct efforts and resources specifically toward the prevention of gun-related incidents, experts say.
“When we focus our policy responses almost entirely on firearms in these events, we overlook major things and we aren’t going to address the root of the problem,” said Laura E. Agnich, an assistant professor of criminal justice and criminology at Georgia Southern University in Statesboro.
That narrow focus can lead to “knee jerk” responses such as overly broad zero-tolerance policies and costly building upgrades, instead of research-based school climate measures and carefully practiced safety procedures, Ms. Agnich said.
In the 2010-11 school year, U.S. public schools reported 5,000 cases of student possession of a firearm or explosive device, and 72,300 cases of possession of a knife or other sharp object, according to the most recent information available from the U.S. Department of Education…. http://www.edweek.org/ew/articles/2014/04/23/29knives_ep.h33.html

NI Direct of Northern Ireland has some great information for parents about knife crimes.

In the article, Keeping your child safe from knife crime, NI Direct advises:

Know the law
Before talking to your child about knives, you need to know the facts:
• it is illegal for anyone to carry a knife if they intend to use it as a weapon – even in self defence
• police can search anyone they suspect of carrying a knife
• carrying a knife could mean being arrested, going to court and getting a criminal record, or even a prison sentence
• Knives, offensive weapons and the law (crime, justice and the law section)
Knives in school
It is a criminal offence to have a knife or other weapon on school premises. If a knife or other weapon is found on a pupil, the police will be called and it is likely the pupil will be arrested.
• School attendance and absence: the law
• If your child is arrested and charged
Talking to your child about knives
The best way to stop your child getting involved with knives is to talk to them about the dangers. This may not be easy as they may not want to talk about it, but keep trying as this is the first step to keeping your child safe.
You should remind them that by carrying a knife they are:
• giving themselves a false sense of security
• potentially arming an attacker, increasing the risk of getting stabbed or injured
• breaking the law
Keep a look out
Sometimes there might be obvious reasons for you to think your child is carrying a knife – such as a knife going missing from the kitchen.
However, there are other more subtle signs that you and the parents of your child’s friends can look out for such as:
• school’s not going well or they don’t want to go in to school at all
• they’ve been a recent victim of theft/bullying/mugging
• a different network of friends who may be older than your child…

School violence is a complex set of issues and there is no one solution. The school violence issue mirrors the issue of violence in the larger society. Trying to decrease violence requires a long-term and sustained focus from parents, schools, law enforcement, and social service agencies.
