Local election officials are the administrators of democracy, but we know little about their views. This paper draws from two national surveys of local election officials. The authors find that local election officials generally support the goals of the federal Help America Vote Act but are less enthusiastic about the actual impact of the legislation. Implementation theory helps explain their evaluation of federal reforms. Goal congruence with reform mandates, resource availability, and a willingness to accept federal involvement predicts support for these reforms. Federal policy changes have promoted electronic systems, and some of the authors' findings are relevant to research on e-government. Users of electronic voting machines tend to have high confidence in them despite the significant criticism the machines have faced. Local election officials who support e-government generally are more likely to more positively evaluate federal reforms.  相似文献

I examine why states violate norms they embrace as members of international society. The rationalist answer, that norms are violated whenever they conflict with interests, is underspecified and empirically challenged. Constructivists cannot address violations well from their structural, sociological perspective. I argue from political psychology that violations stem from the motivated biases of actors who face a moral dilemma between personal desires and social constraints. These biases compel leaders to interpret norms and situations in a manner that justifies violation as socially acceptable. The ability to do so depends on the norm and the situation. The more parameters a norm possesses, and the more ambiguous those parameters are, the easier it is for actors to interpret them favorably to justify violation. Oftentimes norms are what states make of them. If the situation is plausible for states to claim exemption, they violate; otherwise they are constrained. The U.S. invasion of Panama illustrates these dynamics.  相似文献

Although agricultural biotechnology has been a seminal reference point in risk perception studies, public awareness of their exposure to risk deriving from this new technology has been minimal at best. However, recent events indicate there may be growing public concern as new variations of this technology appear. Understanding what drives perceptions of benefits from the third generation of the agricultural biotechnology and what determines public worries are keys for the future of this technology. To this end, this study analyzes survey data from the midsouth region of the United States to construct four separate regression models of perceived benefits from and worries over plant‐made industrial products and plant‐made pharmaceuticals. Findings suggest that while prior experience with and knowledge about agricultural biotechnology has an impact on perceptions of benefits and worries, trust in farmers plays a highly important role in determining perceptions.  相似文献

This edition of Policing: A Journal of Policy and Practice isdevoted to police performance management. Several of the articlesherein trace the origins of this style of police managementand the influences that have brought it about. Others appraiseits effects on matters as diverse as domestic violence, criminalinvestigation and the closure of police stations. They do so,not only from the perspective of the UK, but also from thoseof France, the United States and elsewhere; police performancemanagement is widespread and so are the issues that it raises.

Abstract

Can reinstatement of encoding context aid eyewitness identification? Two experiments are reported in which participants were asked to identify, from both a Blank and a Filled lineup, a target seen 1-week (Experiment 1) or 3-months (Experiment 2) earlier in a staged live interaction. Identifications were made following either a no context reinstatement (NCR), a CI-type reinstate context (CI-CR), a mental and physical (M&PCR) context reinstatement or a multiple reinstatement of context (Multi-CR) manipulation. In Experiment 1 in the Blank lineup condition, correct rejection (CR) and false identification (FID) rates did not differ between the four context manipulation conditions. However, within the different conditions only Multi-CR showed a significant difference between CR and FID. In the Filled lineup condition, neither correct identification (CID), FID, nor non-identification (NID) rates differed between context conditions. Within the four context conditions only Multi-CR produced significantly more CID than FID. However, the difference between CID and NID in this condition did not differ reliably. In Experiment 2, with the Blank lineup, while the rate of CR did not differ between the three context conditions, the rate of FID did, with Multi-CR producing reliably fewer than the other two conditions. In the Filled lineup condition, no differences between the three conditions for NID or FID were observed but a difference did appear for CID, with CI-CR producing the greatest number of hits. These variable results are discussed in terms of the need to consider other factors in explaining supposed context effects on recognition.  相似文献

ABSTRACT

Federal funding streams, the International Association of Chiefs of Police, and policing executives and scholars alike have advocated for more researcher-practitioner partnerships in American law enforcement. While a few studies have explored the growth and prevalence of research partnerships in policing, less attention has been placed on the organizational correlates of such collaborative relationships. Using a nationally representative sample of US law enforcement agencies, the current study investigated participation in what we term ‘rigorous partnerships’ – more formal, long-term relationships between researchers and practitioners with increased opportunity for interactive knowledge exchange. Policy implications and directions for future research are discussed, with a specific focus on the barriers and impediments that both parties face for successful collaborative efforts and research translation.  相似文献
