Parenthood Affects Gay Couples' Health and HIV Risk, Study Says

June 27th 2012

Holding Hands

Gay parents face many of the same challenges as straight parents when it comes to sex and intimacy after having children, according to a new study of gay fathers. The findings suggest that gay male couples who are raising children may experience lifestyle changes that could reduce their HIV risk.

"When gay couples become parents, they become very focused on the kids, they are tired, there is less time for communication and less desire for sex," said Colleen Hoff, professor of sexuality studies at San Francisco State University. "They go through a lot of the same changes as heterosexual couples who have kids."

Nationwide, approximately one in five gay male couples is raising children. Hoff and colleagues studied whether becoming a parent causes gay dads to change their lifestyle in ways that protect them from risky sexual behavior, or if the stress of parenting leads to increased health risks such as infidelity and unprotected sex with outside partners. The researchers interviewed 48 gay male couples who are raising children together. Read more ..

After Child Dies, Mom's Risk of Early Death Skyrockets

June 27th 2012

victim

In the first two years following the death of a child, there is a 133% increase in the risk of the mother dying, a new study from the University of Notre Dame shows.

Researchers William Evans, a health and labor economist at Notre Dame, and Javier Espinosa of the Rochester Institute of Technology, studied 69,224 mothers aged 20 to 50 for nine years, tracking the mortality of children even after they had left the household. It is the first study of its kind using a large, nationally representative U.S. data source.

According to the study, this heightened mortality is concentrated within the first two years following the death of a child, regardless of the age of the child at the time of death. There also appeared to be no difference in results based on household income, mother's education, family size, the child's sex or the child's cause of death.

The sample was composed of women who are married (84 percent), white (87 percent) and non-Hispanic (91 percent). Slightly more than half the mothers were between the ages of 20 and 34. Read more ..

Denser Development is Good for Single-Family Home Values

June 26th 2012

Flint Michigan

How do denser neighborhoods affect property values? And what's the economic value of walkable neighborhoods?

A study conducted by researchers at the University of Washington College of Built Environments and a South Korean university shows that, contrary to popular belief, there's a positive association between higher neighborhood density and the value of single-family residential properties.

Researchers modeled the values of single-family homes, multifamily rental buildings, commercial spaces and offices in King County, Wash., which includes Seattle. They used property values as a measure of economic value, analyzing them in relation to neighborhood characteristics that correlate with walking, including access to open space and public transportation, mixed-use zoning and pedestrian infrastructure such as sidewalks. They learned that pedestrian aids, such as sidewalks and shorter street blocks, as well as a mix of retail, commercial and residential properties significantly contributed to increases in multifamily rental property values.

Soup Kitchens now Daily Fare for Impoverished Greece

June 25th 2012

Homeless in Athens

As Greece approaches five years of recession, the number of its citizens unable to provide food for themselves is increasing. Soup kitchens in Athens used to be the preserve of undocumented immigrants and the homeless, but now more people from the general population use them too.

It's just before lunchtime. Bowls of hot pasta are being made up for more than a hundred children. But this is not a school. It's a facility run by the municipality of Athens to feed those who can no longer afford to feed themselves. More and more Athenians are coming here - especially pensioners, and families with children.

It's run by George Apostolopolos and a team of volunteers. And though money from the city government has been sufficient so far, he's not sure how long that will continue.

"We are afraid about the future because we don't know about the next day - that is the biggest problem we have, it is a little unknown the future, we try to do the best," Apostolopolos said.

Earlier, before the television cameras showed up, the courtyard was full of adults of all ages lining up for food. But filming the event was not allowed. Many people don't want their families to know they are here. Read more ..

Google Project Aims To Preserve Dying Languages

June 24th 2012

Lost Language

Type the term "endangered languages" into Google and click on a few of the links. It won't take long to come upon some cold, hard facts: There are between 6,000 and 7,000 languages in use around the world today, but half of them could be gone by the year 2100 -- victims of globalization and the dominance of languages like English, Chinese, and Spanish.

You'll also find stories of the linguists who are struggling to respond. They face an uphill battle to document and preserve these dying languages -- and the unique cultures they encode -- before silence sets in. That Google search, however, will also likely lead you to the Endangered Languages Project, an initiative launched on June 21 by the U.S.-based Internet giant itself. It's an effort that linguists say shines a much-needed spotlight on a subject that gets little attention from the wider world. Read more ..

Many international food vendors are trying to make an impact in the U.S. market. The National Association for Specialty Foods says the fastest emerging cuisine is Latin, followed by Indian and Eastern European. The recent Summer Fancy Food Show in Washington is the largest of its kind in North America.

Mame Diene remembers the ancient baobab tree in the courtyard of her family home. As a child, she was not allowed to climb it or cut its branches.  Now, she honors these trees of Senegal by selling their powder as a natural dietary supplement.  "It’s wonderful for the heart. You have twice as more anti-oxidants in this fruit than goji berries, six times more than in blueberries,” she said.

It is one of 180,000 items at the Fancy Food Show where food producers sell their trendiest goods to specialty shops and markets.  Countries here sponsor a complete row of booths.  The Korean Pavilion, featured spice noodles and beef. The Indonesian Pavilion -- healthy dried noodles and coconut products. And, the Chilean Pavilion with its own food truck.  Trade commissioner Alejandro Buvinic says Chile has plenty to offer the American market. Read more ..

Immigrants Change Australia's Cultural Identity

June 23rd 2012

Australia Mines

A census is revealing how immigration from Asia and the boom in mining are reshaping modern Australia.  The census data indicates the country is becoming increasingly multicultural. According to census data compiled last year by the Australian Bureau of Statistics, nearly 22 million people now reside in Australia.  But behind the population statistics lies a portrait of a growing multicultural society influenced by a rise in immigration and the development of new economic centers.

The census shows how Australia’s mining bonanza is reshaping the way the nation lives. More people are moving to the boom states of Western Australia and Queensland in search of work in the resources industry, which is powered by exports of iron ore and coal, mostly to Asia.

The sector has helped Australians become richer, own more cars and live in larger homes during a period of global financial crises. The data also highlights Asia's growing influence. More migrants are coming from India and China, which is Australia's biggest trading partner.  The census reflects the shift in those economic and social ties. After English, Mandarin Chinese has replaced Italian as the most common language spoken in Australian homes. Read more ..

Ancient Jugs Hold the Secret to Practical Mathematics in Biblical Times

June 22nd 2012

Spherical jugs ancient Mediterranean

Archaeologists in the eastern Mediterranean region have been unearthing spherical jugs, used by the ancients for storing and trading oil, wine, and other valuable commodities. Because we’re used to the metric system, which defines units of volume based on the cube, modern archaeologists believed that the merchants of antiquity could only approximately assess the capacity of these round jugs, says Prof. Itzhak Benenson of Tel Aviv University’s Department of Geography.

Now an interdisciplinary collaboration between Prof. Benenson and Prof. Israel Finkelstein of TAU’s Department of Archaeology and Ancient Near Eastern Cultures has revealed that, far from relying on approximations, merchants would have had precise measurements of their wares—and therefore known exactly what to charge their clients.

The researchers discovered that the ancients devised convenient mathematical systems in order to determine the volume of each jug. They theorize that the original owners and users of the jugs measured their contents through a system that linked units of length to units of volume, possibly by using a string to measure the circumference of the spherical container to determine the precise quantity of liquid within.

The Paralympic Games will be staged in London less than three weeks after the 2012 Summer Olympics end.

Charles Teye is a disabled Ghanaian powerlifter who is headed to London in late August to show off his skills and try to win a medal.

Teye has great hopes of winning a medal in the bench press in the 67.5 kilogram weight class.  He says he was just an infant when he lost both his legs because of an infection.

"In the twinkle of an eye they realized that the whole legs had become black and spotted.  And so they quickly rushed me to the hospital.  I was here for three days and then the legs started flowing water.  It looked like when you pour hot oil on you, you know it swells and it starts flowing water.  And so, in like two to three weeks they realized the legs were coming off," Teye recalled. Charles credits a radio broadcast with helping to develop his interest in powerlifting.  He says he heard an announcement about sports opportunities for disabled athletes. Read more ..

'Identity Politics' Play a Role in US Elections

It is human nature to identify with others who look and act like us, and share our values.  The political process in the United States - and nearly everywhere else on Earth - taps into that self-identification as a means of motivating voters.

While many voters would say they cast their ballots on the basis of where the candidates stand on key issues, some of them are swayed by a candidate’s color…or ethnicity…or other factors.  And that's called "Identity Politics."

"When people vote, they like to vote for people [who are] like them. Someone who has the same race, someone who has the same sex, someone who has the same religion, or someone who has the same political views," says Mark Rom of Georgetown University. Rom and other analysts say that before the 2008 South Carolina primary, presidential candidate Hillary Clinton had some support from African American voters.  Then, her husband, former President Bill Clinton, compared then-Senator Barack Obama’s bid to that of another, earlier black candidate.

One hundred years ago, Morgan Pharmacy opened its doors in Washington. Despite economic ups and downs, the small, family-owned pharmacy has thrived. But how is it staying in business today with a larger drugstore just down the street?

Morgan Pharmacy has an old-fashioned feel, with its display of old prescription bottles and the original shelves from when the store opened in 1912. Pharmacist Barry Deutschman bought the store 20 years ago. “During the time period between then, and the time we stopped carrying tobacco, you can see people would rest their cigarettes on counter here,” he said.

The pharmacy is located in a residential neighborhood of Washington and most people hear about it word of mouth. “Once somebody comes in here who’s never been here they love the place,” said Deutschman. “And they want to come back.”

How Food Packaging Affects Food Purchases

Long before deciding on “paper or plastic” at the checkout, shoppers make a plethora of choices at the grocery store, especially in the produce aisle.

Packaging influences the way fruits and vegetables are chosen by consumers, according to a Michigan State University study.

The study found that shoppers prefer to purchase produce that come in a rigid, bio-based plastic container with a long shelf life and a low price. So much so that consumers will opt for sweet cherries in these kinds of containers rather than the loose ones in a bag.

“Consumers believe the type of packaging material could affect the quality of the food product, and the rigid container may provide better protection compared to the flexible bag,” said Georgios Koutsimanis, MSU packaging researcher. “The preference for bio-based versus petroleum-based plastics shows an increased awareness of the environmental aspects of packaging materials.” Read more ..

Tajik Mullahs Warn Of New Threat In Temporary Marriages

Tajik wedding

Mosque sermons in Tajikistan tend to focus on issues that affect people's everyday lives. These days, the hot-button topic of many sermons in Dushanbe has been temporary marriages -- a phenomenon that was almost unheard of in Tajik society until recently.

Recently, at a gathering following Friday Prayers on June 8, prominent Dushanbe Imam Eshon Abdul-Basir Saidov warned women against entering into temporary marriages, which religious leaders say have become a trend in Dushanbe over the past two or three years.

Echoing concerns voiced by his fellow imams, Saidov says dozens of Tajik women have fallen victim to "Iranian-style temporary marriage," known as mut'a. Fairly widespread, and legally approved in predominantly Shia Iran, mut'a is a fixed-term marriage in Shi'a Islam which automatically dissolves upon the completion of a term agreed upon by both parties prior to the marriage.

Many Poor, Pregnant Women with HIV not Screened for Depression

It seems logical that programs to screen and manage depression in pregnant, HIV-positive Medicaid patients should already be in place, but they aren't.

It's the kind of glaring oversight that Rajesh Balkrishnan, associate professor at the University of Michigan College of Pharmacy, said he finds all the time in his research on health disparities. Balkrishnan also has an appointment in the School of Public Health.

"We find that many of these things are such common sense that they should already be in place and being done," said Balkrishnan. "Yet, time and again, we find nothing is being done, though these problems exist."

In a recent paper, Balkrishnan and co-authors found that roughly 28 percent of the low-income, HIV-positive pregnant women reported depression. The numbers could be much higher because the study only captured the women who were being treated for depression. Read more ..

More to Facial Perception Than Meets The Eye

Wimbleton crowd

People make complex judgements about a person from looking at their face that are based on a range of factors beyond simply their race and gender, according to findings of new research funded by the Economic and Social Research Council (ESRC).

The findings question a long-held belief that people immediately put a person they meet into a limited number of social categories such as: female or male; Asian, Black, Latino or White; and young or old.

Dr Kimberly Quinn at the University of Birmingham found that people 'see' faces in a multiple of ways. This could have wider importance in understanding stereotyping and discrimination because it has implications on whether and how people categorise others.

Categorisation is not done purely on the physical features of the face in front of us, but depends on other information as well, including whether the person is already known and whether the person is believed to share other important identities with us. Read more ..

With the opposition and the Kremlin vying for their attention, Muscovites were spoilt for choices this year over how to celebrate June 12, Russia's national holiday. 

Opposition forces on June 12 held a march in downtown Moscow, the first mass protest since Vladimir Putin returned to the Kremlin last month for a third presidential term.

Tens of thousands joined the march despite rainy skies and fears of a police crackdown. The rally came one day after the homes of key opposition figures were raided and just over a month after riot police violently disbanded a similar protest in the Russian capital. While the march has proceeded peacefully so far, authorities appeared intent on disrupting it. They summoned opposition leaders for interrogation, forcing them to miss much of the rally, and organized an unprecedented host of events that critics say were designed to draw people away from the protest.

Dakar Fashion Week celebrates its 10th year with the biggest lineup yet. The organizers of the international event aim to reach the heights of fashion weeks in Paris and New York, while remaining distinctly African.

High fashion is nothing new in Africa. And Senegalese designer Adama Ndiaye says it has its own special quality.

"We do one piece, one by one. We're not sending it to the factory because we don't have a big factory," Ndiaye said. "It's something we've been doing forever." But the industry, like many on the continent, is developing.

To help it along, Ndiaye started Dakar Fashion Week.  Ten years on, the event is drawing the attention of industry notables from all over Africa and the world. Originally from Cameroon, Marcial Tapolo came from Paris to participate for the second time. "It's like a high-class show that she's trying to do. Very sophisticated, which is rare in Africa, as a fashion show," he said. Despite the international presence, most of the talent is local, in a deliberate effort to showcase Senegalese designers and models.

Wake up, America, and lose some weight–it's keeping you tired and prone to accidents. Three studies being presented today at sleep 2012 conclude that obesity and depression are the two main culprits making us excessively sleepy while awake.

Researchers at Penn State examined a random population sample of 1,741 adults and determined that obesity and emotional stress are the main causes of the current "epidemic" of sleepiness and fatigue plaguing the country. Insufficient sleep and obstructive sleep apnea also play a role; both have been linked to high blood pressure, heart disease, stroke, depression, diabetes, obesity and accidents.

"The 'epidemic' of sleepiness parallels an 'epidemic' of obesity and psychosocial stress," said Alexandros Vgontzas, MD, the principal investigator for the three studies. "Weight loss, depression and sleep disorders should be our priorities in terms of preventing the medical complications and public safety hazards associated with this excessive sleepiness."

Early Learning About Spatial Relationships Boosts Understanding of Numbers

June 13th 2012

boy and math

Children who are skilled in understanding how shapes fit together to make recognizable objects also have an advantage when it comes to learning the number line and solving math problems, research at the University of Chicago shows.

The work is further evidence of the value of providing young children with early opportunities in spatial learning, which contributes to their ability to mentally manipulate objects and understand spatial relationships, which are important in a wide range of tasks, including reading maps and graphs and understanding diagrams showing how to put things together. Those skills also have been shown to be important in Science Technology, Engineering and Math (STEM) fields.

Scholars at UChicago have shown, for instance, that working with puzzles and learning to identify shapes are connected to improved spatial understanding and better achievement, particularly in geometry. A new paper, however, is the first to connect robust spatial learning with better comprehension of other aspects of mathematics, such as arithmetic.

"We found that children's spatial skills at the beginning of first and second grades predicted improvements in linear number line knowledge over the course of the school year," said Elizabeth Gunderson, a UChicago postdoctoral scholar.

In addition to finding the importance of spatial learning to improving understanding of the number line, the team also showed that better understanding of the number line boosted mathematics performance on a calculation task.

"These results suggest that improving children's spatial thinking at a young age may not only help foster skills specific to spatial reasoning but also improve symbolic numerical representations," said co-author Susan Levine, a leading authority on spatial and mathematical learning. "This is important since spatial learning is malleable and can be positively influenced by early spatial experiences," added Levine, the Stella M. Rowley Professor in Psychology at UChicago.

HIV Superinfections Appear Common

They’re called HIV “superinfections” and a study indicates they’re much more common than first thought. Researchers say this raises concerns about possible resistance to treatment and may require new approaches to AIDS vaccine research. Dr. Andrew Redd said there are HIV infections and then there are superinfections.

“A superinfection occurs when an individual is initially infected with a strain or strains of HIV. And then at some point later on – after that person has developed an initial immune response to their first infecting strain – at that later time point they come into contact through risky behavior with a second viral strain and then are superinfected with that second strain,” he said. Redd is the lead author of the study and a scientist at the National Institute of Allergy and Infectious Diseases. He said prior to the research done in Uganda it was thought that superinfections were rare, occurring in intravenous drug users or men who have sex with men. Not so. “What we found in our study was that when we looked at a general population of heterosexual individuals in Uganda we found that it actually isn’t as rare as what we thought. And that it is occurring at a significant rate even in the general population,” he said. Read more ..

Immigrant Students Lobby for a US Dream

Millions of illegal immigrants have been drawn to the United States by employers looking for cheap labor.  Those who came with their parents as young children grow up culturally indistinguishable from their American-born peers.  But they are bluntly reminded of their status as undocumented outsiders when they apply for college financial assistance. A group of such students is trying to remedy the situation in New York State.

Undocumented students from Lehman College in New York City don academic robes for a protest in the office of State Assembly Speaker Sheldon Silver. They are almost immediately ushered out, their protest being deemed illegal.  It came at the end of a day of lobbying for passage of the New York DREAM Act, legislation that would make undocumented students eligible for college loans.  

The day began with a chartered bus ride to the state capital in Albany.  Melissa Garcia says dire economic circumstances in her native Colombia forced her mother to come to the United States 11 years ago.  “There are many undocumented youths who are brought here as early as six months.  They are babies.  They were not aware they were being brought, so going back is not a solution.  They do not know the language, they do not know their country.  This is what they call home," she said. “People want to know who we are," she said while leading a chant.

The sponsor of New York's DREAM Act, State Senator Bill Perkins, said the measure would lead to enactment of the federal DREAM Act, which would grant citizenship to undocumented students. “I think it will sort of light the movement, the flame of support, that I think will trigger similar DREAM Acts throughout the country and alert the national legislature, the government, congresspeople and the president that it’s time to pass the DREAM Act on the federal level," he said.

Heaping Urban Trash May be More Serious than Climate Change

Heaping urban trash may be an even more daunting global phenomenon than climate change, the World Bank warned in a recent report. What a Waste: A Global Review of Solid Waste Management reveals that by 2025, city dwellers could produce as much as 2.2 billion tons of solid waste a year, up 70% than the 1.3 billion tons currently generated.

More waste is generated in cities than rural areas because more packaging is used and less is recycled, and because people living in rural areas are less likely to have a consumption-driven lifestyle. But getting a handle on the problem, particularly in developing countries, requires a strong social contract between the municipality and community, according to the report–a serious challenge in parts of the Middle East and North Africa. City dwellers will produce 1.42 kg of trash per day by 2025

By 2025, 4.3 billion living in cities throughout the planet will generate about 1.42 kg/capita/day of municipal solid waste, which will create a huge environmental and financial burden for the local governments tasked with managing it. Untreated solid waste emits methane, a potent greenhouse gas, and chemicals from plastic and other packaging leach into waterways. The World Bank sites untreated waste as one of the major causes of pollution in developing countries that are ill-equipped to handle mounting waste. Read more ..

Habitually sleeping less than six hours a night significantly increases the risk of stroke symptoms among middle-age to older adults who are of normal weight and at low risk for obstructive sleep apnea (OSA), according to a study of 5,666 people followed for up to three years. The participants had no history of stroke, transient ischemic attack, stroke symptoms or high risk for OSA at the start of the study, being presented today at SLEEP 2012.

Researchers from the University of Alabama at Birmingham recorded the first stroke symptoms, along with demographic information, stroke risk factors, depression symptoms and various health behaviors. After adjusting for body-mass index (BMI), they found a strong association with daily sleep periods of less than six hours and a greater incidence of stroke symptoms for middle-age to older adults, even beyond other risk factors. The study found no association between short sleep periods and stroke symptoms among overweight and obese participants. Read more ..

  A U.S.-based organization is carrying on the legacy of the late basketball star Manute Bol by continuing to build schools and work for reconciliation in South Sudan. The recent work comes despite South Sudan’s many struggles during its first of year of existence as a country. Immediately as he enters the Washington offices of the U.S. aid group Sudan Sunrise, executive director Tom Prichard points to a series of pictures high up on the wall.

“We were visiting an elementary school to talk about the needs for schools in southern Sudan," he explained. "Manute was in terrible pain. He was in so much pain he had to use a wheelchair. Manute spoke seated the whole time, but when it was all over he said, ‘I want them to see how tall I am.’” The last picture shows Prichard holding up Bol so the American schoolchildren could see the full physical range of the 2.31-meter-tall basketball defensive specialist, who played for a decade in the National Basketball Association.

New research shows that sleep loss markedly exaggerates the degree to which we anticipate impending emotional events, particularly among highly anxious people, who are especially vulnerable.

Two common features of anxiety disorders are sleep loss and an amplification of emotional response. Results from the new study suggest that these features may not be independent of one another but may interact instead.

Researchers from the Sleep and Neuroimaging Laboratory at the University of California, Berkeley, used brain scanning on 18 healthy adults in two separate sessions, one after a normal night's sleep and a second after a night of sleep deprivation. During both sessions, participants were exposed to an emotional task that involved a period of anticipating a potentially negative experience (an unpleasant visual image) or a potentially benign experience (a neutral visual image).

High Levels of Omega-3 Fatty Acids in Breast Milk of Amerindian Women

June 9th 2012

infant formula

Working with researchers at the University of Pittsburgh and the Cincinnati Children's Hospital, anthropologists at UC Santa Barbara have found high levels of beneficial omega-3 fatty acids in the breast milk of economically impoverished Amerindian woman as compared to women in the United States. The study compared breast milk fatty acid composition in U.S. and Tsimane women. The Tsimane live in Amazonian Bolivia, and eat a diet consisting primarily of locally grown staple crops, wild game, and freshwater fish. Samples of Tsimane mothers' milk contained significantly higher percentages of the omega-3 fatty acid docosahexaenoic acid (DHA), which is crucial for infant cognitive and visual development.

Additionally, the percentages of DHA in breast milk did not significantly decrease across the first two years postpartum, the period during which infant brains experience peak growth and maximal uptake of DHA. This was also true for the U.S. women, and the study suggests that extended breastfeeding by both U.S. and Tsimane mothers may provide infants with a constant source of DHA during the critical period of brain development.

"The fatty acid composition of breast milk varies with the fatty acid composition of a mother's diet and fat stores. Ancestral humans likely consumed omega-6 and omega-3 fatty acids in equal proportions," said Melanie Martin, a doctoral student in UCSB's Department of Anthropology, and the study's lead researcher. "Tsimane mothers' omega-6 to omega-3 ratios were four to one, much closer to the ancestral estimates than observed in U.S. women." Read more ..

Underprivileged Kids Get Free Prom Clothes

June 9th 2012

Graduates

In the United States, when students graduate from high school, many celebrate that achievement by going to prom. It is a dance party where students dress up in formal gowns and tuxedos. But not every student who wants to go can afford to dress for the occasion. Organizations across the United States provide free dresses and suits so students can go to prom. A program called The Cinderella and Prince Charming Project allows teens from some of the roughest neighborhoods in the country to celebrate a milestone.

From sequins to lace, in reds, blues and blacks, gowns and tuxedos fill the courtyard of the "A Place Called Home" youth center. It is located in a Los Angeles neighborhood with a strong gang presence. The center provides mentoring, year-round education programs, and free dresses once a year for graduating high school students, like Leslie Pine, who otherwise could not afford to buy a dress for the celebration called prom.

What Does It Mean To Be Cool? It May Not Be What You Think

June 8th 2012

being cool

Do rebelliousness, emotional control, toughness and thrill-seeking still make up the essence of coolness? Can performers James Dean and Miles Davis still be considered the models of cool?

Research led by a University of Rochester Medical Center psychologist and published by the Journal of Individual Differences has found the characteristics associated with coolness today are markedly different than those that generated the concept of cool.

“When I set out to find what people mean by coolness, I wanted to find corroboration of what I thought coolness was,” said Ilan Dar-Nimrod, Ph.D., lead author of “Coolness: An Empirical Investigation.” “I was not prepared to find that coolness has lost so much of its historical origins and meaning—the very heavy countercultural, somewhat individualistic pose I associated with cool.

“James Dean is no longer the epitome of cool,” Dar-Nimrod said. “The much darker version of what coolness is still there, but it is not the main focus. The main thing is: Do I like this person? Is this person nice to people, attractive, confident and successful? That’s cool today, at least among young mainstream individuals.”

In research that has developed over several years, Dar-Nimrod, currently a post-doctoral fellow in the Medical Center’s Department of Psychiatry, and his colleagues recruited almost 1,000 people in the Vancouver, British Columbia, area, who completed an extensive questionnaire on the attributes, behaviors and individuals they associated with the word cool.

In the journal article, the research is described as the first systematic, quantitative examination of what characteristics recur in popular understandings of the cool personality.

The researchers conducted three separate studies. In Study 1, participants generated characteristics that they perceived to be cool. In Study 2, two samples of participants rated dozens of these characteristics on two dimensions: coolness and social desirability. In Study 3, participants rated friends both on their coolness and on a variety of personality descriptors that were identified as relevant in the other studies. Read more ..

Cities Mobilize Against Urban Corruption

June 8th 2012

More than half of the world’s people now live in urban areas and the United Nations expects two-thirds of humanity will be city dwellers by mid-century. Representatives of nearly 30 cities of the world are participating in a two-day conference in New York City to examine ways of combating corruption that is accompanying such rapid urbanization.

If taxpayers fund a kilometer of city sidewalks but only get 800 meters, they are robbed by corrupt officials who steal one fifth of the money. The mayor of Caracas, Venezuela, Antonio Ledezma, shared that observation with officials from 26 cities of the world, from the national government of South Africa and regional governments of Catalonia and Quebec. Ledezma warned persistent corruption can be lethal for democracy. Ledezma says this is because corruption generates mistrust in democracy itself. He says there are those who naively come to the conclusion or believe that authoritarian dictatorships or governments can efficiently control corruption. Read more ..

DC Community Activists Work to Curb Youth Violence

June 7th 2012

Kids Jail

 A study by the U.S. Centers for Disease Control and Prevention says youth violence is the second leading cause of death for Americans between the ages of 10 and 24. Researchers suggests the violent behavior can start early in a child's life and continue into young adulthood. The problem is particularly widespread in urban, African-American communities.

From street corner fights to school yard assaults, violence among young African-Americans is on the rise. While youth violence has decreased nationally since 2004, the Centers for Disease Control and Prevention (CDC) says black children represent an overwhelming majority of crime victims and crime perpetrators. "I literally have seen my friends die. My friends got shot in front of me. I have held my friends while they die," said Tony Lewis Jr., who knows the tragic consequences of youth violence in Washington. He grew up on this crime-ridden neighborhood block known as Hanover Place. When he was just nine, his father was given a life prison sentence for his role in a large cocaine distribution network. 

"In these type of [poor] neighborhoods a lot of people went towards crime because that is what poverty does, and when crime comes violence comes," he said. Lewis says youth violence among African-Americans also stems from a lack of educational opportunities. He says there's a need for adult mentors to get young people to change their harmful behavior. Read more ..

Demand for Ivory Increases Elephant Poaching

June 7th 2012

 An International Fund for Animal Welfare report has linked the increasing number of elephants being killed in Africa with the rising demand for ivory in China. According to the report,  in 2011 poachers gathered more than 5,200 elephant tusks,  (23 tons) resulting in the deaths of more than 2,500 elephants. It says the majority of that ivory went to China.

“The growing demand for ivory products in China is actually driving elephant poaching across Africa," explained Elizabeth Wamba, communications manager for the International Fund for Animal Welfare in Eastern Africa. "It has just been too high. It has escalated by, in some places, in hundreds of percentages.” The report quotes an auction newsletter describing the 2011 sale of more than 11,000 ivory pieces in mainland China for a total of $95.4 million, an increase of 107 percent from the previous year.

Sens. Sessions and Paul Seek Big Cuts to Food Stamps Program in Farm Bill

June 7th 2012

American poverty

Conservative Sens. Jeff Sessions (R-Ala.) and Rand Paul (R-Ky.) have offered amendments to the farm bill that would greatly cut federal spending on food stamps.

At the same time, liberal Sen. Kirsten Gillibrand (D-N.Y.) is attempting to restore the $4.3 billion in food stamp cuts already in the bill and the White House is saying that the farm bill's current cut is too much.

Paul’s amendment would cut the most, by block-granting the entire food stamp program. The House-passed GOP budget backs this approach.

Sessions has four amendments to limit eligibility and trim spending more modestly. “We are confident that modest and thoughtful reforms to the food stamp program can achieve substantial budgetary savings for taxpayers, while ensuring that fewer dollars are wasted and improperly spent – targeting resources to intended recipients,” Sessions spokesman Stephen Miller said. One would restore an asset test for eligibility, saving $12 billion.

“Through a system known as categorical eligibility, states can provide benefits to those whose assets exceed the statutory asset limit as long as they receive some other federal benefit. One state went so far as to determine individuals as food-stamp eligible solely because they received a brochure for another benefit in the mail,” said Session’s office. Read more ..

Adolescents and Young Adults with Mental Health Disorders at Risk of Long-Term Opioid Use

June 7th 2012

Boy in pain

Long-term use and abuse of opioid painkillers, such as OxyContin and Vicodin, has markedly increased in the United States in the last two decades. Of note, prescription opioids constitute 86.9 percent of prescription drug misuse among high school students. And last week in a two-day U.S. Food and Drug Administration public meeting, officials questioned the use of long-term opioids for chronic pain due to a lack of evidence for the effectiveness and concerns about the potential risk for addiction. While previous studies have shown that depression and substance abuse peaks during adolescence and young adulthood, studies assessing the link between mental health issues and opioid use in this population were lacking.

Laura Richardson, MD, and a team at the Seattle Children’s Research Institute and the University of Washington conducted a longitudinal study to examine the association between mental health disorders and subsequent risk for long-term opioid use among adolescents and young adults ages 13 to 24. They found that those with mental health disorders were not only more likely to be prescribed opioids for chronic pain but also 2.4 times more likely to become long-term opioid users than those who didn’t have a mental health disorder. The study also found that long-term opioid use was more common among males, older youth and youth who lived in communities that were poorer, had more white residents, and had fewer residents who had attended college.

Religious Control of Women's Sexuality promotes Certainty about Paternity

Religious practices that strongly control female sexuality are more successful at promoting certainty about paternity, according to a study published in the current issue of the Proceedings of the National Academy of Sciences. The study analyzed genetic data on 1,706 father-son pairs in a traditional African population—the Dogon people of Mali, West Africa—in which Islam, two types of Christianity, and an indigenous, monotheistic religion are practiced in the same families and villages. "We found that the indigenous religion allows males to achieve a significantly lower probability of cuckoldry—1.3 percent versus 2.9 percent," said Beverly Strassmann, lead author of the article and a biological anthropologist at the University of Michigan.

In the traditional religion, menstrual taboos are strictly enforced, with women exiled for five nights to uncomfortable menstrual huts. According to Strassmann, the religion uses the ideology of pollution to ensure that women honestly signal their fertility status to men in their husband's family. "When a woman resumes going to the menstrual hut following her last birth, the husband's patrilineage is informed of the imminency of conception and cuckoldry risk," Strassmann said. "Precautions include postmenstrual copulation initiated by the husband and enhanced vigilance by his family."

Across all four of the religions practiced by the Dogon people, Strassmann and colleagues detected father-son Y DNA mismatches in only 1.8 percent of father-son pairs, a finding that contradicts the prevailing view that traditional populations have high rates of cuckoldry. A similar rate of cuckoldry has been found in several modern populations, but a key difference is that the Dogon do not use contraception.

The study, which was supported by funding from the National Science Foundation, is part of Strassmann's ongoing, 26-year study of the Dogon people.

"The major world religions sprang from patriarchal societies in which the resources critical to reproduction, whether in the form of land or livestock, were inherited from father to son down the male line," Strassmann and colleagues write. "Consistent with patrilineal inheritance, the sacred texts set forth harsh penalties for adultery and other behaviors that lower the husband's probability of paternity. The scriptures also place greater emphasis on female than on male chastity, including the requirement of modest attire for women and the idealization of virginity for unmarried females."

Air Pollution Linked to Chronic Heart Disease

June 6th 2012

Air pollution, a serious danger to the environment, is also a major health risk, associated with respiratory infections, lung cancer and heart disease. Now a Tel Aviv University researcher has concluded that not only does air pollution impact cardiac events such as heart attack and stroke, but it also causes repeated episodes over the long term.

Cardiac patients living in high pollution areas were found to be over 40 percent more likely to have a second heart attack when compared to patients living in low pollution areas, according to Dr. Yariv Gerber of TAU's School of Public Health at the Sackler Faculty of Medicine. "We know that like smoking cigarettes, pollution itself provokes the inflammatory system. If you are talking about long-term exposure and an inflammatory system that is irritated chronically, pollution may well be involved in the progression of atrial sclerosis that manifests in cardiac events," explains Dr. Gerber.

The Obamas And the New Politics of Race

June 6th 2012

With the 2012 US presidential election campaign in full swing, the meaning and significance of Barack Obama and his presidency are once again in the spotlight. Has the election of Barack Obama served as the watershed moment for American politics and race relations that many predicted? A number of experts in the field of critical race theory attempt to answer this question in a special issue of Qualitative Sociology: The Obamas and the New Politics of Race,¹ published by Springer and available to the general public. This series of six articles showcases the most recent critical sociological work on race, racism, and politics through the lens of Barack Obama's presidency.

One article provides a timely examination of how the concept of "family" has been used to both address and mask social inequalities generally, and racial inequalities in particular. In her article entitled "Just another American story? The first Black First Family," former American Sociological Association president Patricia Hill Collins shows – by highlighting their own 'family stories' during the 2008 campaign and in the post-election years – how the Obamas have been able to reintroduce race, gender, labor and equality into public policy discussions in a time when such debates are often deemed risky.
