Policy Considerations for States Supporting Stem Cell Research: Evidence from a Survey of Stem Cell Scientists

Five states now provide funding for stem cell research, and many states are developing or debating stem cell research policies. Despite this interest, little data exist to help policy makers design policies or forecast the impact of new legislation. This article reports novel data from two surveys: one directed at those most affected by these policies—stem cell scientists—and one at a group of biomedical researchers working in less contentious fields. These data identified relatively high mobility among stem cell scientists, particularly in states with restrictive policies, and a strong preference for states with permissive policies. These findings suggest that state-specific policies may prove to be effective recruiting tools. They also suggest specific recruitment strategies and highlight the importance of first-mover advantage as states compete for the same limited pool of mobile scientists. This research aims to provide a factual basis to support ongoing policy formulation in the area.     

论冲突法上的适应问题

冲突法上的适应问题是一种法律关系的准据法同他种法律关系的准据法分别属于不同法律秩序时,应如何调整两者在适用上可能产生相互矛盾及不调和的问题。增强准据法的适应性或者说对准据法加以调整是当代冲突法的一个新动向。可以说,适应或调整程序浓缩了确定准据法的技术,冲突法上的某些制度本身就是适应观念的体现。在适应问题的解决方面,目前还难以制定统一的一般准则,总的来说,有冲突法的适应方法、实体法的适应方法和比较法的适应方法。适应问题不仅存在于法律适用阶段,而且也发生在管辖权协调和外国判决执行方面。     

Agenda Power in the Italian Chamber of Deputies, 1988–2000

We present strong evidence that governing coalitions in Italy exercise significant negative agenda powers. First, governing parties have a roll rate that is nearly 0, and their roll rate is lower than opposition parties' roll rates, which average about 20% on all final‐passage votes. Second, after one controls for distance from the floor median, opposition parties have higher roll rates than government parties. These results strongly suggest that governing parties in Italy are able to control the legislative agenda to their benefit. We also document significantly higher opposition roll rates on decree‐conversion bills and budget bills than on ordinary bills—results consistent with our theoretical analysis of the differing procedures used in each case.     

The Consequences of Electoral Institutions for Careerism

Although electoral institutions have been shown to have a variety of effects, scholars have not investigated if certain voting rules enable politicians to enjoy longer legislative careers. I took advantage of a natural experiment—a sudden transition from a semiproportional voting rule to single‐member districts with plurality voting (SMDP)—to measure the effect of electoral institutions on careerism. My analysis revealed that voting rules have a profound influence on the dynamics of legislative careers: politicians elected under SMDP are far less likely to suffer electoral defeat or to retire than those elected via cumulative voting. The findings of this study not only provide additional insight into the seat safety of politicians elected in first‐past‐the‐post systems, but moreover offer new criteria by which to evaluate the choice of electoral institutions.     

Justice, at last, in the archetypical patent entitlement dispute

Development and usage of a NIST standard reference material for real time PCR quantitation of human DNA

National Institute of Standards and Technology SRM 2372 human DNA quantitation standard has been produced to support the need for a human-specific DNA quantitation standard in forensic casework and calibration of new quantitative polymerase chain reaction (qPCR) assays. The conventional DNA concentration has been assigned with one of the U.S. National Reference UV/Visible Spectrophotometers, assuming an absorbance of 1.0 at 260 nm equals 50 ng/μL of double stranded DNA. In addition, an interlaboratory study has been conducted, to verify that the SRM 2372 materials perform well in currently used DNA quantitation assays by the forensic DNA community. Each unit of SRM 2372 consists of three well-characterized DNA extracts. Component A is a single-source human male material derived from blood. Component B is a multiple-source human female material derived from blood. Component C was purchased as a purified unsheared genomic human DNA (Sigma-Aldrich Co., St. Louis, MO) obtained as a lyophilized human genomic extract and has both male and female donors. SRM 2372 is intended to enable the comparison of DNA concentration measurements across time and place. Manufacturers can use SRM 2372 to validate the values assigned to their own reference materials. Individual forensic laboratories can use SRM 2372 to validate DNA quantitation methods and to verify the assigned concentration of in-house or commercial DNA calibration standards.     

Minimum wages and the economic well‐being of single mothers

Using pooled cross‐sectional data from the 1992 to 2005 March Current Population Survey (CPS), this study examines the relationship between minimum wage increases and the economic well‐being of single mothers. Estimation results show that minimum wage increases were ineffective at reducing poverty among single mothers. Most working single mothers were not affected by minimum wage hikes because they already earned wages above state and federal minimum wages. And less‐educated single mothers who were affected did not see a rise in net income because of negative employment and hours effects. For this low‐skilled population, a 10 percent increase in the minimum wage was associated with an 8.8 percent reduction in employment and an 11.8 percent reduction in annual hours worked. © 2008 by the Association for Public Policy Analysis and Management
