We investigated how well adults could recognize the faces of children when they differed in appearance from photographs shown
in an alert. College students in three studies saw a mock AMBER Alert while watching a television show. The children appeared
either well-groomed with positive affect (as in a school photograph) or disheveled with poor affect (as abducted children
might appear). Recognition accuracy and confidence were significantly lower when the faces differed in appearance from the
alert displayed during the television show. Thus, AMBER Alerts may be more effective if they are accompanied by more than
one type of photograph of a missing child, particularly if a photograph is shown in which the child does not appear well-groomed
and happy. 相似文献

Community Development Block Grant Spending Revisited: Patterns of Benefit and Program Institutionalization 总被引:1,自引:0,他引:1
This article analyzes Community Development Block Grant (CDBG)spending by local governments between 19881992. We addressfour issues examining actual expenditure patterns in a smallcentral city and five satellite cities in Michigan: changesin CDBG expenditure patterns; levels of social targeting; theextent of institutionalization of expenditure patterns; andthe level of privatization of CDBG spending. We conclude thatwhile spending for housing and public works is related to thefiscal health of cities, expenditures for economic developmentand social services are related to political characteristics.Further, local governments exceed federal social targeting guidelines.Finally, while there is little privatization, the communitiesstudied evidence modest levels of program innovation in thelater years of the CDBG program. 相似文献

Jurors have accumulated prior knowledge of crime categories that influences their verdict choices (V. L. Smith, 1991, 1993). The present research investigates whether this prior knowledge also influences the fact-finding process by operating as an expectancy for information processing. Consistent with the expectancy hypothesis, Study 1 demonstrated that people are more susceptible to misleading information that is perceived to be typical of the crime in question than misleading information that is atypical. Studies 2 and 3 revealed that people's intrusion errors also contain more typical than atypical information. These results indicate that people's prior knowledge of crime categories does indeed serve as an expectancy for fact-finding. Thus, prior knowledge plays a broader role than previously appreciated. The implications of this breadth are discussed. 相似文献

Stimulating ‘green’ technological innovation: An analysis of alternative policy mechanisms 总被引:2,自引:0,他引:2
As our understanding of human impacts on the environment has increased, it has become clear that we need to move toward a closed-loop industrial society in order to avoid undesirable health and ecosystem consequences. Achievement of this goal depends on radical technological innovation in both products and processes. This paper explores how to design public policy mechanisms to stimulate rather than impede pollution-preventing technological innovation. It begins with a discussion of the role of government in civilian technology development and diffusion. It then sets out six design criteria for policy to promote green technology innovation. Based on this set of design criteria, the article assesses the potential and limitations of current U.S. policy approaches to stimulate technological innovation that moves us toward a minimal waste society. The main conclusions of this assessment are as follows. Over the past decade, the U.S. environmental policy system has experienced a variety of reforms and new initiatives, many aimed directly at promoting environmentally-friendly technological change. The strengths of these reforms are to increase the information that the private sector has about the magnitude and cost of their environmental impacts and to allow greater flexibility in the technologies that firms choose to meet environmental regulations and goals. Because of these reforms, firms are likely to undertake technological innovation for the environment in situations with clear short-term economic benefits, i.e. to capture the much heralded win-win potential of environmental regulation. However, these reforms have significant weaknesses as well. Unless policy provides stronger political or economic incentives and clearer signals about future environmental performance requirements, we are unlikely to be able to drive technological innovation in industries where the pay-off is more longterm or uncertain, and thus will make only limited progress toward the goal of a minimal waste society. 相似文献
