Public policy disputes involving complex scientific issues usually entail conflicts not only over those scientific issues, but also over the distribution of gains and losses. The presence of scientific or technical dimensions to a dispute should not be allowed to mask underlying distributional considerations. On the other hand, science-intensive disputes require special attention. Merely resolving distributional conflicts without incorporating the best scientific judgment will produce unwise and potentially dangerous results. The usual adversarial approach that characterizes the handling of such disputes by agencies and courts is less than ideal for creating an understanding of scientific evidence or the resolution of scientific differences. A process of mediation, already applied in a number of significant cases, offers strong promise as a superior approach. 相似文献

I review theories and evidence on wage‐setting institutions and labor market policies in an international comparative context. These include collective bargaining, minimum wages, employment protection laws, unemployment insurance (UI), mandated parental leave, and active labor market policies (ALMPs). Since it is unlikely that an unregulated private sector would provide the income insurance these institutions do, these policies may enhance economic efficiency. However, to the extent that unemployment or resource misallocation results from such measures, these efficiency gains may be offset. Overall, Scandinavia and Central Europe follow distinctively more interventionist policies than the English‐speaking countries in the Northern Hemisphere. Possible explanations for such differences include vulnerability to external market forces and ethnic homogeneity. I then review evidence on the impacts of these policies and institutions. While the interventionist model appears to cause lower levels of wage inequality and high levels of job security to incumbent workers, it also in some cases leads to the relegation of new entrants (disproportionately women, youth, and immigrants) as well as the less skilled to temporary jobs or unemployment. Making labor markets more flexible could bring these groups into the regular labor market to a greater extent, at the expense of higher levels of economic insecurity for incumbents and higher levels of wage inequality. © 2011 by the Association for Public Policy Analysis and Management. 相似文献

This note describes a low-cost online portal called “the Cambridge Randomizer”, which enables treatment providers to conduct random assignment themselves, while the researcher still maintains control over the entire process and the integrity of the allocation process. 相似文献86.

As the challenges of maintaining (or, in the US case, attaining) affordable universal coverage multiply, the debate about what constitutes "real" reform intensifies in Western health care systems. The reality of reform, however, lies in the eyes of myriad beholders who variously enshrine consumer responsibility, changes in payment systems, reorganization, and other strategies -- or some encompassing combination of all of the above -- as the essential ingredient(s). This debate, increasingly informed by the agendas of health services researchers and health policy analysts, arguably serves as much or more to becloud as to clarify the practical options policy makers face and remains severely imbalanced with respect to the institutional sectors on which it concentrates, the fields of knowledge on which it draws, and the roles it envisions for markets and the state. 相似文献

Research in many forensic science fields commonly uses domestic pigs (Sus spp.) as proxies for human remains, due to their physiological and anatomical similarities, as well as being more readily available. Unfortunately, previous research, especially that which compares the decompositional process, has shown that pigs are not appropriate proxies for humans. To date, there has not been any published research that specifically addresses whether domestic pigs are adequate human proxies for the geophysical detection of clandestine graves. As such, the aim of this paper was to compare the geophysical responses of pig cadavers and human donor graves, in order to determine if pigs can indeed be used as adequate human proxies. To accomplish this, ground penetrating radar (GPR) and electrical resistivity tomography (ERT) responses on single and multiple pig cadaver graves were compared to single and multiple human donor graves, all of which are in known locations within the same geological environment. The results showed that under field conditions, both GPR and ERT were successful at observing human and pig burials, with no obvious differences between the detected geophysical responses. The results also showed that there were no differences in the geophysical responses of those who were clothed and unclothed. The similarity of the responses may reflect that the geophysical techniques can detect graves despite what their contents are. The study implications suggest that experimental studies in other soil and climate conditions can be easily replicated, benefiting law enforcement with missing persons cases. 相似文献

I have been coming to China for more than 30 years. I have traveled all across the country,visiting over 100 cities together with my long-term partner, Adam Zhu, for research and interviews, books and essays, television and documentaries. I have given much thought, over the years, as to what has brought about China's develop-mental miracle.
