MacDonaldIt is no secret that advances in technology can greatly impact the value of workers’ skills. Older workers often find the updating of complex technology uneconomic, while younger workers acquire and readily employ skills tailored to the newest technology. The result: the latter group’s productivity rises, diminishing the value of output produced by their older counterparts. A recently published study by Glenn MacDonald, Washington University’s John M. Olin Distinguished Professor of Economics and Strategy, is the first to model and explain the nature and severity of this effect.

Charter schools are attended disproportionately by poor, minority students.Since their creation in the early 1990s, charter schools have come under fire from many civil rights supporters. “Traditional advocates of civil rights claim that charter schools are but another opportunity for whites to escape from the public school system and gain advantage for their children at taxpayers’ expense,” says Tomiko Brown-Nagin, associate professor of law and of history at Washington University in St. Louis. “This criticism overlooks the astounding fact, however, that most charter schools have been established in poor, minority neighborhoods and are attended disproportionately by poor, minority students — those whose schools and neighborhoods have been untouched by Brown v. Board of Education.”

Should Alzheimer’s disease patients be told of the diagnosis? If so, when, how and by whom? Brian D. Carpenter, Ph.D., an assistant professor of psychology in Arts & Sciences at Washington University in St. Louis, conducted a review of related study literature that shows there is little consensus among clinicians on the issue of disclosing a dementia diagnosis and great room for much more research. Carpenter’s review, done with research assistant Jennifer Dave, was published in the April 2004 issue of The Gerontologist. “If contemporary debate and practice are any indication, there is no consensus on these matters,” Carpenter says in the article “Disclosing a Dementia Diagnosis: A Review of Opinion and Practice, and a Proposed Research Agenda.”

WUSTL researchers have found no convincing evidence that people can delay or hasten their own deaths through sheer will.Many of us know stories about terminally ill friends or relatives who were able to battle their illnesses in order to survive until a birthday or other important occasion. In much of medicine, it’s an accepted “truth” that people can hang on or give up and somehow influence the timing of their own deaths. But in reviewing every study on the subject of delaying death, Washington University behavioral medicine researchers have found that there’s no evidence to support the idea that terminally ill people can have an effect on when they die.

Are humans inherently good? The prevailing view in popular and scientific literature is that humans and animals are genetically driven to compete for survival, thus making all social interaction inherently selfish. According to this line of reasoning, known as sociobiology, even seemingly unselfish acts of altruism merely represent a species’ strategy to survive and preserve its genes. But Robert W. Sussman, Ph.D., a professor of anthropology in Arts & Sciences at Washington University in St. Louis, argues that this is a narrow and simplistic view of evolutionary theory that fails to explain many aspects of sociality among mammals in general and primates in particular. In “The Origins and Nature of Sociality,” a new book Sussman co-edited, he and other researchers challenge the proponents of sociobiology. “The ‘selfish gene’ hypothesis is inadequate,” Sussman says.

Are altruism and morality artificial outgrowths of culture, created by humans to maintain social order? Or is there, instead, a biological foundation to ethical behavior? In other words, are we inherently good? The prevailing view in popular and scientific literature is that humans and animals are genetically driven to compete for survival, thus making all […]

NorthDouglass C. North, Ph.D., the Spencer T. Olin Professor in Arts & Sciences and a co-recipient of the Nobel Memorial Prize in Economic Science, joined a panel of distinguished economists in Denmark May 24-28th for an intensive forum exploring the costs and benefits of ongoing efforts to address critical global challenges, such as war, famine and disease.

Sadat”The story of abuse at Abu Ghraib prison is shocking, and certainly requires a full investigation, and perhaps the criminal prosecution of some of those either directly or indirectly responsible,” says Leila N. Sadat, vice-president and co-director of studies of the American branch of the International Law Association. “However, one thing the story is not, is new. While leading an International Bar Association training program for Iraqi lawyers, judges and prosecutors in Dubai in February, I saw a story on CNN International which reported that 17 soldiers had been relieved of command due to allegations of torture and abuse. Sadat comments on her discussions with Iraqi lawyers as well as the treatment of civilians in the prison.

Areas of red and yellow show increased uptake of the altanserin tracer due to binding to the serotonin receptors.Most of us feel sad from time to time, even very sad, but during a bout of clinical depression, a person is unable to escape their low mood for several weeks at a time. A popular and effective treatment for depression involves a class of drugs called selective serotonin reuptake inhibitors (SSRIs). Those drugs increase serotonin levels in the brain and help relieve symptoms of depression, and most scientists believe the brain chemical serotonin plays a key role in depression. Now neuroscience researchers at Washington University School of Medicine in St. Louis have found that in people who are depressed, a key brain structure has an abnormally low number of cellular serotonin receptors.
