Social scientists traditionally have described local governments as competing with each other for residents and businesses. But in a number of metropolitan areas in the United States, local governmental officials have formed groups voluntarily to enhance the economic development of multijurisdictional areas. This article develops a theory that asserts the key determinants of the formation of these regional partnerships for economic development are cooperative norms—or a tradition of regional cooperation—and need. The theory also posits that norms influence regional partnerships' organizational structure and processes. Hypotheses are tested empirically using data from all metropolitan areas in the United States and responses to a national survey of regional partnerships for economic development. Results provide some support for the theory that norms and need are both positively related to the formation of regional partnerships for economic development. Support is weak that norms are related the organizational characteristics of regional partnerships for economic development.  相似文献

The present study tested the Two-Judgment Theory of Eyewitness Identification Accuracy. Specifically, the extent to which participants were able to engage in an absolute judgment strategy was manipulated by varying the time available to view a lineup. Providing a limited exposure to a lineup should “interrupt” decision making, whereby witnesses can only engage a relative strategy, thus leading to higher false positive responding given a target-absent lineup. Seventy-four adults viewed a 1-minute video that exposed them to an unknown target and subsequently viewed the lineup for a limited (2 s) or an unlimited amount of time. Although false positive rates were similar across conditions, accurate witnesses were more confident than inaccurate witnesses. Confidence was negatively correlated with response latency such that witnesses who took more time to make a decision were less confident in their decisions compared to witnesses who made more rapid decisions. Response latency did not differ for accurate and inaccurate witnesses. Limitations and suggestions for future research on the Two-Judgment Theory are discussed.  相似文献

Research Summary Attention to gang issues has dramatically increased in the last several decades, both in the scholarly literature and in law enforcement. Despite widespread attention to the gang problem, researchers, police officers, and lawmakers have yet to agree on definitions used to characterize and understand the problem. This article summarizes the existing literature concerning the importance of accurately defining and classifying gang members, documents and analyzes state and federal gang legislation in the United States, and provides a detailed analysis of one state's system that might serve as a useful model for other states. Policy Implications Serious risks to public safety and civil liberties are associated with Type 1 and Type 2 classification errors regarding gang membership. The wide variation in state statutory definitions of “gang member” and in the construction and administration of gang databases presents major challenges for policymakers and academic researchers. This article addresses these challenges and argues that a more rigorous and unified system, based on one state's existing model, might be possible and could offer significant advantages in our efforts to address the delinquent and criminal behavior of gangs throughout the United States.  相似文献
