Gender gap disappears in school math competitions, study shows

Gender gap disappears in school math competitions, study shows
2013-02-26
(Press-News.org) The idea that boys are better at math and in competitions has persisted for a long time, and now we know why: Nobody bothered to schedule the rematch.

Most school math contests are one-shot events where girls underperform relative to their male classmates. But a new study by a Brigham Young University economist presents a different picture.

Twenty-four local elementary schools changed the format to go across five different rounds. Once the first round was over, girls performed as well or better than boys for the rest of the contest.

"It's really encouraging that seemingly large gaps disappear just by keeping them in the game longer," said BYU economics professor Joe Price.

Price co-authored the study with the University of Miami's Christopher Cotton and Rutgers' Frank McIntyre. Their report is published by the Journal of Economic Behavior & Organization.

In the contest, students were paired against a classmate to see who got the most questions right during a 5-minute quiz. In case of a tie, the student who finished first won. The winner earned raffle tickets for a small prize.

Because the schools shared past test scores with the researchers, they could compare how similarly talented boys and girls performed. Even though these matches look even on paper, for some reason boys have the edge when it's the first foray into a competitive setting. On a test worth ten points, it usually amounts to a one-point edge for boys in the initial round.

"We don't know if it's boys getting excited and over-performing or if it's girls being too uncomfortable with the situation," Price said.

But here's another twist: Six classrooms de-emphasized the speed component. Ties weren't decided by who finished first. And though there was still just five minutes on the clock, the students were told, "It's not a race."

With those two small adjustments, girls competed evenly with boys from the start. BYU math professor Jessica Purcell, who was not involved with the study, wasn't surprised that the format adjustments resulted in more parity.

"In mathematical settings without time pressure or competition, such as classes I have taught or classes I have taken, males and females seem to do equally well," said Purcell, a recipient of the prestigious Sloan Research Fellowship.

Since boys' competitive advantage is so short-lived, the study authors suggest that a little encouragement could go a long way.

"What motivated us was how to get girls to thrive in a competitive environment," said Price, noting that he has two daughters. "You might guess that girls would shy away from competitive work environments. What our results would hint is that if you convince them to stick around and give it a shot, they will acclimate and do just fine."

OHSU scientists first to grow liver stem cells in culture, demonstrate therapeutic benefit

2013-02-26
PORTLAND, Ore. — For decades scientists around the world have attempted to regenerate primary liver cells known as hepatocytes because of their numerous biomedical applications, including hepatitis research, drug metabolism and toxicity studies, as well as transplantation for cirrhosis and other chronic liver conditions. But no lab in the world has been successful in identifying and growing liver stem cells in culture -- using any available technique – until now. In the journal Nature, physician-scientists in the Papé Family Pediatric Research Institute at Oregon Health ...

Tweaking gene expression to repair lungs

Tweaking gene expression to repair lungs
2013-02-26
PHILADELPHIA — Lung diseases such as asthma and chronic obstructive pulmonary disease (COPD) are on the rise, according to the American Lung Association and the National Institutes of Health. These ailments are chronic, affect the small airways of the lung, and are thought to involve an injury-repair cycle that leads to the breakdown of normal airway structure and function. For now, drugs for COPD treat only the symptoms. "A healthy lung has some capacity to regenerate itself like the liver," notes Ed Morrisey, Ph.D., professor of Medicine and Cell and Developmental ...

Prenatal DHA reduces early preterm birth, low birth weight

2013-02-26
LAWRENCE — University of Kansas researchers have found that the infants of mothers who were given 600 milligrams of the omega-3 fatty acid DHA during pregnancy weighed more at birth and were less likely to be very low birth weight and born before 34 weeks gestation than infants of mothers who were given a placebo. This result greatly strengthens the case for using the dietary supplement during pregnancy. Susan CarlsonThe results are from the first five years of a 10-year, double-blind randomized controlled trial to be published in the April issue of the American Journal ...

Some family physicians' offices discriminate against people with low socio-economic status

2013-02-26
TORONTO, Feb. 25, 2013—Some family physicians' offices discriminate against people of low socio-economic status, even when there is no economic incentive to do so under Canada's system of publicly funded universal health insurance, new research has shown. At the same time, offices appear to give preference to people with chronic health conditions, according to the research led by Dr. Stephen Hwang of St. Michael's Hospital. In his study, published today in the Canadian Medical Association Journal, researchers telephoned the offices of family physicians and general practitioners ...

Virus shows promise as prostate cancer treatment

2013-02-26
A recombinant Newcastle disease virus kills all kinds of prostate cancer cells, including hormone resistant cells, but leaves normal cells unscathed, according to a paper published online ahead of print in the Journal of Virology. A treatment for prostate cancer based on this virus would avoid the adverse side effects typically associated with hormonal treatment for prostate cancer, as well as those associated with cancer chemotherapies generally, says corresponding author Subbiah Elankumaran of Virginia Polytechnic Institute, Blacksburg. The modified virus is now ready ...

Higher levels of several toxic metals found in children with autism

2013-02-26
TEMPE, Ariiz. -- In a recently published study in the journal Biological Trace Element Research, Arizona State University researchers report that children with autism had higher levels of several toxic metals in their blood and urine compared to typical children. The study involved 55 children with autism ages 5 years compared to 44 controls of similar age and gender. The autism group had significantly higher levels of lead in their red blood cells (+41 percent) and significantly higher urinary levels of lead (+74 percent), thallium (+77 percent), tin (+115 percent), ...

Study reveals stem cells in a human parasite

Study reveals stem cells in a human parasite
2013-02-26
CHAMPAIGN, lll. — From the point of view of its ultimate (human) host, the parasitic flatworm Schistosoma mansoni has a gruesome way of life. It hatches in feces-tainted water, grows into a larva in the body of a snail and then burrows through human skin to take up residence in the veins. Once there, it grows into an adult, mates and, if it's female, starts laying eggs. It can remain in the body for decades. A new study offers insight into the cellular operations that give this flatworm its extraordinary staying power. The researchers, from the University of Illinois, ...

Global surveys show environmental concerns rank low among public concerns

2013-02-26
2/25/2013, Chicago, IL--A newly released international study reveals that the issue of climate change is not a priority for people in the United States and around the world. The surveys showed that when asked to rank priority worries, people were five times more likely to point to the economy over the environment. Additionally, when asked about climate change, people identified the issue as more of a national problem than a personal concern. Coordinated surveys, conducted by the International Social Survey Programme (ISSP) in 33 countries from 1993 through 2010, "are ...

Researchers explore PKC role in lung disease

Researchers explore PKC role in lung disease
2013-02-26
New research examines the role of PKC in airway smooth muscle contraction and raises the possibility that this enzyme could be a therapeutic target for treating asthma, COPD, and other lung diseases. In the lungs, pathological increases in the contraction of the smooth muscle cells (SMCs) lining airway walls—a process that decreases airflow—contribute to the chain of events leading to asthma and COPD, two common lung diseases. Jose Perez-Zoghbi and colleagues from Texas Tech University Health Sciences Center designed a series of experiments to investigate the role of ...
