School achievement higher for children in nuclear families than for children in blended or single-parent families
Family structure may have an effect on educational outcomes.Educational outcomes of children in stable blended families are substantially worse than those of children reared in traditional nuclear families, according to a study published in the most recent issue of the journal Demography. Both stepchildren and their half-siblings who are the joint children of both parents achieved at similar levels, well below those of traditional nuclear families where all the children are the joint offspring of both parents, according to economists Donna Ginther of the University of Kansas and Robert Pollak of Washington University in St. Louis.
Fewer capital flow restrictions foster stronger economic growth
MacDonaldShaken by numerous accounting-related scandals in recent years, some investors are clamoring for better legal protection for their investments. But does investor protection through government regulation foster economic growth? To assess the widely-held view that it does, WUSTL economics professor Glenn MacDonald and two colleagues have completed a study concluding that the positive effect of investor protection on economic growth is stronger for countries with fewer restrictions on international capital flows.
Scientists find fossil proof of Egypt’s ancient climate
David Kilper / WUSTL PhotoWUSTL researchers are trying to infer the Egyptian climate from the fossil evidence.Earth and planetary scientists at Washington University in St. Louis are studying snail fossils to understand the climate of northern Africa 130,000 years ago. While that might sound a bit like relying on wooly bear caterpillars to predict the severity of winter, the snails actually reveal clues about the climate and environment of western Egypt, lo those many years ago. They also could shed light on the possible role weather and climate played in the dispersal of humans “out of Africa” and into Europe and Asia.
Family trees of ancient bacteria reveal evolutionary moves
Carrine Blank/WUSTL PhotoA WUSTL scientist suggests that Cyanobacteria arose in freshwater environments rather than in the sea.A geomicrobiologist at Washington University in St. Louis has proposed that evolution is the primary driving force in the early Earth’s development rather than physical processes, such as plate tectonics. Carrine Blank, Ph.D., Washington University assistant professor of geomicrobiology in the Department of Earth & Planetary Sciences in Arts & Sciences, studying Cyanobacteria – bacteria that use light, water, and carbon dioxide to produce oxygen and biomass – has concluded that these species got their start on Earth in freshwater systems on continents and gradually evolved to exist in brackish water environments, then higher salt ones, marine and hyper saline (salt crust) environments.
New math model of heart cell has novel calcium pathway
David Kilper/WUSTL PhotoProfessor Yoram Rudy (center), with Ph.D. student Yong Wang (left) and post-doctroal fellow Leonid Livshitz (right), with their ECGI system on a mannequin, comment on the cardiac data.Scientists at Washington University in St. Louis have developed the first mathematical model of a canine cardiac cell that incorporates a vital calcium regulatory pathway with implications for life-threatening cardiac arrhythmias, or irregular heartbeats. Thomas J. Hund, Ph.D., post-doctoral researcher in Pathology ( in Dr. Jeffrey Saffitz laboratory) at the Washington University School of Medicine, and Yoram Rudy, The Fred Saigh Distinguished Professor of Engineering at Washington University, have incorporated the Calcium/Calmodulin-dependent Protein Kinase II (CaMKII) regulatory pathway into their model, improving the understanding of the relationship between calcium handling in cardiac cells and the cell’s electrical activity.
Attempting to protect consumers’ personal data through legislation will not result in free speech violations, says privacy law expert.
Streams of junk mail with personalized offers for a myriad of services seem never-ending. While annoying, these solicitations raise significant privacy concerns about how these companies know so much about the recipient’s life. Many legislators and legal experts shy away from legislation that would protect the privacy of American’s personal information claiming that such rules would violate the First Amendment. But Neil M. Richards, noted privacy law expert and associate professor of law at Washington University in St. Louis, denies such assumptions.
Aceh province can rebuild, but United States needs to assist volunteer groups, says Indonesian expert
John Bowen doing fieldwork in Sumatra, Indonesia, in the late 1970s.Despite suffering large loss of life and devastation of cities and villages from the 9.0 magnitude earthquake and ensuing tsunami, Aceh province in Indonesia can rebuild. And at the same time, the United States can burnish its image among Indonesians — tarnished over the invasion of Iraq — by supporting Indonesian volunteer groups in the rebuilding process, says a sociocultural anthropologist at Washington University in St. Louis who lived in Aceh for five years and has studied its people and culture since 1978.
Financial future may be brighter for those who tithe
Money going to faith-based organizations can bring a financial benefit to donors.In the aftermath of the Asian tsunami, Americans generously donated money to relief groups around the world. But it appears Americans don’t need a major disaster to give money. Annually, Americans donate $183 billion, with nearly half of that amount going to faith-based organizations. Money going to faith-based organizations, such as churches, mosques, the Salvation Army and Catholic Charities, not only can help provide needed social services to communities, but it can also bring a financial benefit to donors, says a noted community development expert at Washington University in St. Louis. “People who donate money on a regular basis take a closer look at where their money is going,” says Stephanie Boddie, Ph.D., assistant professor of social work in the George Warren Brown School of Social Work at Washington University. “They are able to figure out and set aside the money they can donate on a weekly or monthly basis. This can lead to more financial responsibility in the areas of debt repayment and asset building.”
