This article examines the relationship between structural strain (the imbalance between actual and preferred…

The winner’s curse — overestimating the value of an asset and therefore overpaying — is often associated with acquisitions of publicly-traded firms but not with private acquisitions. Using an event study methodology for over 22,000 private acquisitions of U.S. firms between 1985 and 2015, the authors examine a possible winner’s curse for such acquisitions, testing variables to determine what characteristics make a private company more likely to overestimate the asset's value.

Islamist parties throughout the world have routinely disregarded environmental concerns in their discourse and actions. However, Islam as a religion places strong emphasis on environmental protection. Thus, it is puzzling that environmental policy is all but absent from most Islamist platforms, writes Middle East Center research scholar A.Kadir Yildirim.

Regenerative medicine and stem cell research are exciting new fields. But as the fields progress toward clinical therapies, controversies emerge. Hype surrounding stem cell research has caused an increase in their use in interventions that are not clinically proven. Furthermore, the regulatory agencies have a lot of difficulty dealing with cell therapies, which are distinctly different from drugs and medical devices they more commonly approve. To move the field forward, advocates, regulators and scientists need to come together to find new options for stem cell research oversight that protects both the patients and the research field.

Biotechnology scientists must be aware of the broad patent landscape and push for new patent and licensing guidelines, according to a new paper from the Baker Institute.

This research discerns how municipal solid waste (MSW) composition influences the heating value and air pollution for the co-combustion of coal with MSW using five MSW composition scenarios, four of which were derived by a reduction of plastics, organics, paper, or a combination thereof, as compared to the national average MSW composition.

Despite the political nature of stem cell research, this area of science continues to flourish in the United States. In 2011, the NIH funded approximately US$1.2 billion in stem cell research — a steady increase from past years — with US$123 million devoted to human embryonic stem cells. According to the ISI Web of Science, more than 4,000 U.S.-authored stem cell publications were produced in 2011, accounting for approximately 38 percent of the world total. Approximately one-quarter of these publications were collaborations with authors from other countries.
