Parole board members (PBMs) decide whether to release inmates on parole. Decisions may be affected by in‐group bias or stereotypes regarding religion and race. Two experiments investigated whether religious conversions/secular lifestyle changes and race affect mock PBMs' release decisions, emotions, and perceptions. Mock PBMs read a case file of an inmate who was eligible for parole and decided whether to grant parole. Study 1 manipulated whether the inmate had converted to Christianity or Islam, had a secular lifestyle change, or had no lifestyle change. Study 2 also varied race (African American or Caucasian). Race was not a significant factor, possibly because the manipulation was not strong enough to influence participants or because participants did not want to appear racist. Conversions to Islam and Christianity impacted the parole decision, and effects were mediated by believability of the conversion. Secular lifestyle changes affected release decisions and were mediated by perceptions of the inmate and beliefs about his likelihood of recidivism. Such inmates were the most likely to be released and were perceived most positively; their conversions were the most believable. Inmates who made no changes were perceived least positively, indicating that any lifestyle change is better than none. Importantly, no bias towards either religion (Islam, Christianity) was found. Furthermore, conversion type affected how scared PBMs were of the inmate, but this fear did not impact release decisions. 相似文献

For most states the methodology used for assigning Unemployment Insurance tax rates to employers arose when the program was first established in 1935. More than 80 years later, with evolving employment relationships, state systems have become outmoded. This paper critiques current experience rating methods and presents new methodologies that are much easier to operate and that improve the incentives for employers to increase employment. The proposed methods would assess taxes based on employment or payroll variation such that growing firms would have lower taxes. A simulation analysis illustrates the impact of the new methods on employer groups. 相似文献

正When my Chinese fiance and I decided to get married, there was no question about it: We would get our wedding portraits taken at one of the Chinese wedding studios that came with quaint names like "Paris," "Rome," "Golden Ladies," or "Mona Lisa. " "Are you going for the typical Chinese look? Vaseline on the lens, the works?" a British friend asked, in, shall we say, "amused" fashion.It was a Chinese tradition I would come to love; in the West, wedding photos are usually taken only during the ceremony and reception. 相似文献

Enhancing Precision and Clarity in the Study of Policy Narratives: An Analysis of Climate and Air Issues in Delhi,India 下载免费PDF全文

The study of policy narratives is challenged by inconsistencies and a need for more precise definitions and measurements. The goals of this article are to build precision and clarity in the study of policy narratives by developing a network‐based approach—the ego‐alter dyad—for coding characters and their interactions around a policy issue and then to illustrate this approach in the analysis of air and climate issues in Delhi, India. The empirical results show that (1) the same actors are often heroes and villains, (2) heroes and villains are associated with different actions but with similar victims or beneficiaries, (3) narrators differ in their propensity to tell hero‐heavy or villain‐heavy policy narratives, and (4) the proportion of hero‐heavy or villain‐heavy policy narratives changes over time and differs across subtopics. The article concludes with a research agenda for further theoretical and methodological advancement in studying policy narratives. 相似文献

Fluorescence Imaging of Posterior Spiracles from Second and Third Instars of Forensically Important Chrysomya rufifacies (Diptera: Calliphoridae), 下载免费PDF全文

Entomological protocols for aging blowfly (Diptera: Calliphoridae) larvae to estimate the time of colonization (TOC) are commonly used to assist in death investigations. While the methodologies for analyzing fly larvae differ, most rely on light microscopy, genetic analysis, or, more rarely, electron microscopy. This pilot study sought to improve resolution of larval stage in the forensically important blowfly Chrysomya rufifacies using high‐content fluorescence microscopy and biochemical measures of developmental marker proteins. We established fixation and mounting protocols, defined a set of measurable morphometric criteria and captured developmental transitions of 2nd instar to 3rd instar using both fluorescence microscopy and anti‐ecdysone receptor Western blot analysis. The data show that these instars can be distinguished on the basis of robust, nonbleaching, autofluorescence of larval posterior spiracles. High‐content imaging techniques using confocal microscopy, combined with morphometric and biochemical techniques, may therefore aid forensic entomologists in estimating TOC. 相似文献

There is widespread criticism of the behaviour of junior officials in post-communist Europe where they are often accused of treating citizens unfairly and soliciting presents or bribes to solve citizens' problems. To get the perspective of officials themselves we interviewed 1307 junior officials and state employees in Ukraine, Bulgaria, Slovakia and the Czech Republic. This paper focuses on their willingness to accept gifts from clients, their confessions to having done so, and the factors that lead some officials to accept gifts while others do not – factors such as occupational bargaining power and the (related) frequency of offers from clients, economic pressures, national and institutional cultures, fear of punishment, and moral perspectives on charging clients for favours. Economic pressures make officials more inclined to feel that they 'could not afford to refuse' gifts, but this motivation is only weakly related to actual behaviour. Occupational bargaining power and the frequency of offers from clients make them more likely to 'welcome' gifts or accept them 'out of politeness'– and these less excusable motivations are more strongly related to actual gift-taking. 相似文献
