Deception is a useful methodological device for studying attitudes and behavior, but deceptive studies fail to fulfill the informed consent requirements in the U.S. federal regulations. This means that before they can be approved by Institutional Review Boards, they must satisfy the four regulatory conditions for a waiver or alteration of these requirements. To illustrate our interpretation, we apply the conditions to a recent study that used deception to show that subjects judged the same wine as more enjoyable when they believed it had a higher price. 相似文献

The increased burden placed upon the UN Security Council in the post-Cold War era in respect of its discharge of its primary
responsibility for the maintenance of international peace and security has fuelled calls for the greater use of regional arrangements
as agents of the Council, to relieve its burden. However, the various agendas and capabilities of different arrangements make
it difficult to adopt a uniform template of the role which regional arrangements can play as conductors of peace support operations
authorised by the Security Council. This article attempts to provide a framework against which the potential role of different
arrangements as viable agents to which the Security Council can entrust military enforcement operations, before going on to
assess how selected African and European organisations fare against this framework. It will be demonstrated that when assessed
against this framework, the organisations selected for comparison are remarkably similar.

On the basis of prior research findings that employed youth, and especially intensively employed youth, have higher rates
of delinquent behavior and lower academic achievement, scholars have called for limits on the maximum number of hours per
week that teenagers are allowed to work. We use the National Longitudinal Survey of Youth 1997 to assess the claim that employment
and work hours are causally related to adolescent problem behavior. We utilize a change model with age-graded child labor
laws governing the number of hours per week allowed during the school year as instrumental variables. We find that these work
laws lead to additional number of hours worked by youth, which then lead to increased high school dropout but decreased delinquency.
Although counterintuitive, this result is consistent with existing evidence about the effect of employment on crime for adults
and the impact of dropout on youth crime.

The Federal Violent Crime Control and Law Enforcement Act of 1994 bans a group of military-style semiautomatic firearms (i.e., assault weapons) and ammunition magazines capable of holding more than 10 rounds. Ban advocates argue that these weapons are particularly dangerous because they facilitate the rapid firing of high numbers of shots. Though the banned guns and magazines were used in only a modest fraction of gun crimes before the law, it was hypothesized that a decrease in their use might reduce gunshot victimizations, particularly those involving multiple wounds and/or victims. In response to a Congressional mandate for an impact assessment of the law, this study utilized national and local data sources and a variety of analytical techniques to examine the ban's short-term impact on gun violence. The ban may have contributed to a reduction in gun homicides, but a statistical power analysis of our model indicated that any likely impact from the ban will be very difficult to detect statistically for several more years. We found no evidence of reductions in multiple-victim gun homicides or multiple-gunshot wound victimizations. The findings should be treated cautiously due to the methodological difficulties of making a short-term assessment of the ban and because the ban's long-term effects could differ from the short-term impacts revealed by this study. 相似文献

Using historical and numerical analysis and the five-part schema, this study finds that over the past 50 years structural modifications and adaptations by American cities have generally followed the standard S curve of the diffusion of innovation. In tests of Kaufman's and Hirshman's theories of epochs of change from representativeness to administrative efficiency, this study determines that mayor-council cities have, in a standard innovation diffusion S curve, adopted many of the key features of council-manager cities, increasing their administrative efficiency. At the same time, council-manager cities, again in an S curve, have adopted many of the key features of mayor-council cities, increasing their political responsiveness. Fewer cities are now either distinctly mayor-council or council-manager in form, and most cities are structurally less distinct, constituting a newly merged or hybrid model of local government—the type III city. 相似文献
