No general explanation seems to distinguish popular from unpopularuniform state law proposals. Adoption appears to be a productof the timeliness of specific proposals rather than of the wisdomor "necessity" of the movement itself or of the purely technical,legal, or policy merits of individual proposals. Overall, thestates have not been highly responsive to uniform law proposals.The predominant factor discriminating high from low adoptingstates is political culture: moralistic states have, on average,the highest adoption rate; traditionalistic states have thelowest. This finding is plausible in terms of both the "goodcommonwealth" orientation of the moralistic political cultureand the "good government" orientation of many uniform law proposals.  相似文献

Because equity capital is becoming an important financing source for health care organizations, the conversion of many such organizations from nonprofit to for-profit status is a significant public policy issue. Since many states require converting nonprofits to repay the "community" for its investment during the nonprofit status period, three questions arise: (1) How much is the entity worth? (2) How much of that worth should be returned to the community? (3) In what form should it be returned? The paper addresses these questions, and demonstrates why responsible public policy calls for them to be carefully considered if community interests are to be preserved.  相似文献

This article examines the complexities of women’s increasing participation in international development programming for gender equality. Taking a specific setting in rural Kyrgyzstan where one such project has been operating, the researchers discover adverse effects on the local women’s livelihoods, status and health. Women’s contradictions are attributed to the women’s own failures and lacks, creating confusion and frustration among them. Adopting Smith’s institutional-ethnography approach, we explicate and map out the hidden processes which must be held accountable for these reactionary outcomes, taking women’s experiences as entry points to inquiry. We find that the reactionary effects are not accidental but organized, powerfully, systematically but invisibly, by taken-for-granted institutional practices serving the purposes of global development institutions, where women are seen as instruments of global economic growth. The analysis provokes critical discussion of ‘how’ and ‘what’ it takes to transform Central Asian women into ‘empowered’ people.  相似文献

This study examines the relationship between critical incidents, alcohol problems, trauma symptoms, and service utilization across five countries. A sample of 1286 police officers (79% male; 21% female) from five countries (US = 838, Canada = 231, UK = 102, Australia = 58, and New Zealand = 57) completed the Alcohol Use Disorders Identification Test (AUDIT) and the PTSD Checklist – Civilian PCL-C, as well as questions regarding service availability and utilization in an on-line survey. ANOVA and chi-square tests indicate significant country differences on all variables except social stressors. Multivariate analysis of critical incidents, AUDIT, PTSD, and service utilization found negative coping and country of origin mattered. The reasons officers provided for why they felt they could not use available services (i.e., confidentiality, stigma, distrust of department, and ineffective/inadequate) also varied by country, which has important policy implications.  相似文献

In this study, we explore the extent to which diversity of educational levels among research scientists and engineers (RSEs) in the context of a firm’s level of technological diversity influences innovation performance. We used data from the 2004–2008 National R&D Survey in Singapore. The results from 366 firms across different industries indicate that when a firm’s technological domains are heterogeneous, those firms with an RSE workforce comprising similar educational levels have positive innovation performance, measured as the number of patent applications, while those comprising diverse educational levels have negative innovation performance. Our further exploration of the positive interaction between technological domain heterogeneity and similarity of educational levels suggests that firms that had a high ratio of RSEs with lower educational levels had more positive patent outcomes compared to those that had a high ratio of RSEs with higher educational levels. The results show that there are limits to the strength of technological diversity in a firm’s absorptive capacity as explained by organizational demography.  相似文献

It has been widely believed that who bears the burden of proof significantly affects the incentives of the legal parties. In particular, Hay and Spier (J Legal Stud 26:413–431, 1997) argues that if legal parties have a commonly accessible body of evidence (perfectly correlated pieces of evidence), the party who bears the burden of proof will present the evidence if and only if the evidence supports his position, while the other party (without the burden) will refrain from presenting it regardless of whether the evidence supports his position. In this paper, I claim that the result will be dramatically changed if the pieces of evidence that each party possesses are not perfectly correlated. I show that each party will present the evidence that supports his position whenever available, regardless of the burden of proof assignment. This implies that allocating the burden of proof does not matter in terms of information elicitation.  相似文献

Objectives

Our multisite randomized controlled trial reported that police body-worn cameras (BWCs) had, on average, no effect on recorded incidents of police use of force. In some sites, rates of use of force decreased and in others increased. We wanted to understand these counter-intuitive findings and report pre-specified subgroup analyses related to officers’ discretion on activating the BWCs.

Methods

Using pre-established criteria for experimental protocol breakdown in terms of treatment integrity, ten experimental sites were subgrouped into “high-compliance” (no officer discretion applied to when and where BWCs should be used; n?=?3), “no-compliance” (treatment integrity failure in both treatment and control conditions; n?=?4), and tests where officers applied discretion during treatment group but followed protocol in control conditions only (n?=?4).

Results

When officers complied with the experimental protocol and did not use discretion, use of force rates were 37 % lower [SMD?=?(?.346); SE?= .137; 95?% CI (?.614) – (?.077)]; when officers did not comply with treatment protocol (i.e., officers chose when to turn cameras on/off), use of force rates were 71 % higher [SMD?= .392; SE?= .130; 95?% CI (.136) – (.647)], compared to control conditions. When full discretion (i.e., overall breakdown of protocol) was applied to both treatment and control conditions, null effects were registered [SMD?= .009; SE=.070; 95?% CI (?.127) – (.146)], compared to control conditions.

Conclusions

BWCs can reduce police use of force when then officers’ discretion to turn cameras on or off is minimized—in terms of both case types as well as individual incidents. BWCs ought to be switched on and the recording announced to suspects at early stages of police–public interactions. Future BWCs tests should pay close attention to adherence to experimental protocols.

Mistakes in decision-making have been identified as the most common type of error in police investigations. Consequently, wrongful convictions and other types of criminal investigative failure may require a complete case ‘rethinking,’ particularly when new evidence disrupts the existing theory. A rush to judgment resulting in a premature shift from an evidence-based to a suspect-based investigation can produce a number of problematic thinking errors. Faulty assumptions, tunnel vision, groupthink, and other cognitive biases and organizational traps hinder evidentiary interpretation and evaluation. This article outlines a protocol for reviewing evidence and rethinking a wrongful conviction or unsolved crime when the existing investigative theory appears to be incorrect. The protocol involves four stages: (1) evidence; (2) interpretation; (3) patterns; and (4) analysis.  相似文献
