From the 26 July 2013 Science Daily article
Aiming to quell heated national debate about gun control with factual answers, two UC Irvine mathematicians have designed parameters to measure how to best prevent both one-on-one killings and mass shootings in the United States. Their paper appears Friday in the journal PLOS ONE.
“It’s time to bring a scientific framework to this problem,” said lead author Dominik Wodarz, a mathematical biologist who works on disease and evolutionary dynamics. His co-author and wife, Natalia Komarova, a mathematician who studies biomedical and social trends, added: “Can we design a rational way to argue about guns?”
Both were appalled not just by the December shooting deaths of 20 youngsters and eight adults in Newtown, Conn., but also by the bitterly emotional dispute over weapons that erupted anew. They decided to put their professional expertise to work.
“This debate cannot be settled satisfactorily by verbal arguments alone, since these are often driven by opinion and lack a solid scientific backing,” the authors write. “What is under debate is essentially an epidemiological problem: How do different gun control strategies affect the rate at which people become killed by attackers, and how can this rate be minimized?”
The duo reviewed available data stretching as far back as World War I, then drew up equations to compute whether policies ranging from a total firearm ban to “arm everyone” increase or decrease homicides. After running the numbers, they found that in more common domestic and one-on-one crimes, reduced legal gun availability — if properly enforced — is likelier to lower deaths. But in rare mass shootings, armed citizens might save lives if sufficiently trained to avoid accidentally shooting fleeing bystanders.

2013 World Drug Report: stability in use of traditional drugs, alarming rise in new psychoactive substances
2013 World Drug Report: stability in use of traditional drugs, alarming rise in new psychoactive substances
Source: United Nations Office on Drugs and Crime
The 2013 World Drug Report released today in Vienna shows that, while the use of traditional drugs such as heroin and cocaine seems to be declining in some parts of the world, prescription drug abuse and new psychoactive substance [NPS]
abuse is growing. In a special high-level event of the Commission on Narcotic Drugs, UNODC Executive Director Yury Fedotov urged concerted action to prevent the manufacture, trafficking and abuse of these substances.
Marketed as ‘legal highs’ and ‘designer drugs’, NPS are proliferating at an unprecedented rate and posing unforeseen public health challenges. The report shows that the number of NPS reported to UNODC rose from 166 at the end of 2009 to 251 by mid-2012, an increase of more than 50 per cent. For the first time, the number of NPS exceeded the total number of substances under international control (234). Since new harmful substances have been emerging with unfailing regularity on the drug scene, the international drug control system is now challenged by the speed and creativity of the NPS phenomenon.
This is an alarming drug problem – but the drugs are legal. Sold openly, including via the internet, NPS, which have not been tested for safety, can be far more dangerous than traditional drugs. Street names, such as “spice”, “meow-meow” and “bath salts” mislead young people into believing that they are indulging in low-risk fun. Given the almost infinite scope to alter the chemical structure of NPS, new formulations are outpacing efforts to impose international control. While law enforcement lags behind, criminals have been quick to tap into this lucrative market. The adverse effects and addictive potential of most of these uncontrolled substances are at best poorly understood.
The global picture for the use of traditional drugs such as heroin and cocaine shows some stability. In Europe, heroin use seems to be declining. Meanwhile, the cocaine market seems to be expanding in South America and in the emerging economies in Asia. Use of opiates (heroin and opium), on the other hand, remains stable (around 16 million people, or 0.4 per cent of the population aged 15-64), although a high prevalence of opiate use has been reported from South-West and Central Asia, Eastern and South-Eastern Europe and North America.

Nearly all these 5 (of many) findings from the Brookings State of Metropolitan America analyses over the past year have major public health implications, especially
- Americans are increasingly stuck at home
“Americans move around more than their counterparts in other developed countries, but a lot less than they used to. Some fear that in the short run, homeowners are stuck in places with too few jobs, and not able or willing to move to places with healthier labor markets. Longer run, and perhaps more importantly, states and metro areas that relied too heavily on in-migration for growth must re-calibrate their economies to create better, more diverse job opportunities for current and future residents.”
- Minorities are driving growth, replenishing America’s youth
“Large metro areas, and increasingly their suburbs, stand at the forefront of America’s transformation into a multiethnic society. How they respond to and manage that shift, especially the social and economic opportunities they provide to a highly diverse population of families with children, will establish the course for our nation’s well-being over the coming decades. Rapid growth in the immigrant population in some parts of the country produced late-decade policy backlashes that could threaten these places’ longer-run economic well-being.”
- Boomers continue to age, transforming America’s households
“The older population is growing everywhere, and a host of public and private services will be adapted to an aging population in the decades to come. Areas that are also gaining younger populations may have a resource advantage in responding to those changes, compared to rapidly aging northern states and metro areas. Yet because the former areas have more racially and ethnically diverse young people, they too may face challenges in managing competition for scarce public resources between predominantly white seniors and minority families with children.”
- America lost ground in income and poverty in the 2000’s
“Census 2000 captured American households at a high-water mark economically, a far different situation than they faced in 2010. Economic growth strategies for the coming decade must place greater emphasis on achieving shared prosperity that lifts incomes for a broad segment of households. With unemployment projected to remain high for some time, many parts of the country will confront higher fiscal and social burdens associated with poverty, including concentrated poverty, for the foreseeable future. All metro areas, meanwhile, must continue to adapt a traditionally city-focused social services infrastructure for helping the poor to the reality of region-wide needs.”

Do some statistically laden advertisements and Web sites seem misleading? Is there a disconnect between the displayed data in some ads with your gut feelings? But you just cannot put your finger on why you feel distrustful?
Just plain sloppily represented infographics could be creating some of the confusion. Infographic combines an interesting graphical element with hard data. They are commonly seen in the media, including USA Today.
Here are some excerpts from An Epidemic of Bad Infograhics: Depression
In an effort to keep trying to get people’s attention in an increasingly attention-deficit world, we get a lot of inquiries for links to websites promoting education programs and other affiliate websites. The latest effort is focused around “infographics,” those graphics made popular by the USA Todaynewspaper that combines an interesting graphical element with hard data. A well done infographic ostensibly makes data more engaging. A fantastic infographic puts data into proper perspective and gives it valuable context.
What these marketing firms send me, however, are not fantastic or even well-done. So in the interests of demonstrating that any infographic can be worse than no infographic, I’m going to critique one of the latest ones to have come across my desk. It’s about depression, one of the most common and serious mental disorders….
What about your level of depression? Well, according to the infographic — but not the research or mental health professionals — you can have different “depression levels” ranging from “Normal” (what’s a “Normal” depression?) to “Situational” or even “Major.”
Of course, the Diagnostic and Statistical Manual of Mental Disorders (the DSM-IV) doesn’t divide major depression in this manner. Instead, it specifies that major depression can be Mild, Moderate, Severe without Psychotic Features, Severe with Psychotic Features, In Partial Remission, In Full Remission, or Chronic.
I assume “Situational” refers to a completely different mental disorder — Adjustment Disorder with Depressed Mood. The person designing this graphic was obviously not too familiar with the actual information he was asked to illustrate……
