If manufacturing a safer cigarette is technically possible--an open question--then mandating that tobacco manufacturers improve the safety of cigarettes would likely have both positive and negative implications for the nation's health. On the one hand, removing toxins may reduce the incidence of smoking-related diseases and premature mortality in smokers. On the other hand, smokers might be less inclined to quit, those who have quit might resume the habit, and youth who have never smoked will have one less reason to avoid tobacco use. To assess the expected population health impacts of a legislative or regulatory mandate, we created the Tobacco Policy Model, a system dynamics computer simulation model. The model relies on secondary data and simulates the U.S. population over time spans as long as 50 years. Our simulation results reveal that even if requiring cigarettes to be safer makes smoking more attractive and increases tobacco use, a net gain in population health is still possible. 相似文献

Visas and work permits: Possible global negotiating initiatives 总被引:1,自引:0,他引:1
We discuss global options for initiatives intended to ameliorate adverse impacts of visa and work permit systems used by national
governments around the world. We first describe and document some of their effects, noting the relative lack of other research
work on these issues. We then discuss proposals for a new and supplemental global visa structure which have been made as part
of the Mode 4 GATS negotiations in the WTO, suggesting that the GATS/WTO may be an imperfect institutional location for negotiating
on these matters. We then evaluate other approaches, including what realistically could be possible if a new body specifically
created for global negotiation in the area were to be used.

Local government managers are described as key participants in the development of interlocal cooperation, but the interests of city councils in this process have gone largely unstudied. Here, the author addresses the theoretical importance of council-manager relations in interlocal public service cooperation. Three propositions identify areas of shared council-manager responsibility. Evidence from in-depth interviews with city council members is used to assess each proposition. While interlocal partnership has been described as a managerial activity, council members take an interest in network development and agreement assessment. Managers, on the other hand, give greater attention to public participation and education. The evidence refines assumptions about council-manager roles in the formation of cooperative agreements, with important implications for local government management. 相似文献

The existing literature does not agree on the optimal jury size. We demonstrate that the probability of type I and type II errors is not sensitive to the number of jurors under the following three conditions: jurors receive independent signals about a defendant’s guilt during the evidence stage of the trial; the jurors truthfully reveal their signals before deliberations begin through their votes on the first ballot; and the jury’s deliberation follows a random walk. Since the opportunity cost of jury service is positive, this implies an optimal jury size of one. 相似文献

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures. 相似文献
