Applying an abductive mixed‐methods approach, we investigate the informal status systems in three women's prison units (across two prisons) and one men's prison unit. Qualitative analyses suggest “old head” narratives—where age, time in prison, sociability, and prison wisdom confer unit status—are prevalent across all four contexts. Perceptions of maternal “caregivers” and manipulative “bullies,” however, are found only in the three women's units. The qualitative findings inform formal network analyses by differentiating “positive,” “neutral,” and “negative” status nominations, with “negative” ties primarily absent from the men's unit. Within the women's units, network analyses find that high‐status women are likely to receive both positive and negative peer nominations, such that evaluations depend on who is doing the evaluating. Comparing the women's and men's networks, the correlates of positive and neutral ties are generally the same and center on covariates of age, getting along with others, race, and religion. Overall, the study points to important similarities and differences in status across the gendered prison contexts, while demonstrating how a sequential mixed‐methods design can illuminate both the meaning and the structure of prison informal organization. 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

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.536.
The increase in punitive sentiment in America over the last four decades is frequently attributed to changes in criminal justice policies and programs. While scholars have studied the impact of legislation and policy on justice system outcomes, less attention has focused on the role of political actors in legislative bodies who are largely responsible for enacting criminal justice legislation. The current study addresses this gap by examining the social organization of federal crime control policy in the U.S. Congress over a forty-two year period (1973–2014). Drawing from research on social network mechanisms, we examine whether crime control legislation was more politically attractive relative to other legislative topics, and whether Democrats and Republicans pursue these policies by working together or competing against each other. Our results provide novel insight into the mechanisms that contributed to the punitive movement at the federal level. 相似文献

While type determination on bullets has been performed for over a century, type determination on cartridge cases is often overlooked. Presented here is an example of type determination of ejector marks on cartridge cases from Glock and Smith & Wesson Sigma series pistols using Naïve Bayes and Random Forest classification methods. The shapes of ejector marks were captured from images of test‐fired cartridge cases and subjected to multivariate analysis. Naïve Bayes and Random Forest methods were used to assign the ejector shapes to the correct class of firearm with success rates as high as 98%. This method is easily implemented with equipment already available in crime laboratories and can serve as an investigative lead in the form of a list of firearms that could have fired the evidence. Paired with the FBI's General Rifling Characteristics (GRC) database, this could be an invaluable resource for firearm evidence at crime scenes. 相似文献

This study examined the test validity of the respondent validity scales of the Ruff neurobehavioral inventory (RNBI). In a private practice sample of motor vehicle accident pain patients (n?=?54) without neurologic injury, the scores obtained for these scales were compared with and correlated with equivalent ones on the Millon clinical multi-axial inventory III (MCMI III) and the Detailed assessment of post-traumatic stress (DAPS). Results revealed that there was a consistent pattern of convergence and divergence in response styles across the three instruments. In terms of the RNBI interscale correlations, in particular, the results suggested that premorbid positive impression management and postmorbid negative impression management are related in this type of sample. These findings add to the concurrent validity of the RNBI, suggesting that the instrument provides relevant incremental information about the type of population studied. Limitations of the study and ideas for future research were discussed. 相似文献

Fatal bronchial asthma is classically characterized in pathology textbooks and journal articles as associated with lung hyperinflation at autopsy. The following is a report of a case of fatal bronchial asthma associated instead with bilateral lung collapse. This manifestation of asthma at autopsy has not been previously reported, to my knowledge. A 31-year-old man with a history of recurrent asthma was found in an unresponsive state in his automobile after a low-speed collision. Medical personnel during the resuscitation noted a decrease in breath sounds bilaterally and some wheezing. There was no escaping air with needle thoracostomies at the outset. Cardiac monitoring demonstrated pulseless electrical activity during most of the 30-minute resuscitation attempt. An autopsy disclosed collapsed lungs bilaterally. Microscopic examination of the lungs disclosed the characteristic histopathologic features of bronchial asthma. 相似文献

The study finds that open government does not only have effect on economic prosperity, but on social capital and environment through the mechanisms of Rule of Law and Control of Corruption. The role of Rule of Law and Control of Corruption are emphasized in this study, because of their significance in mediating open government and prosperity. Unless mechanisms like regulation formulation, law enforcement and control of corruption are not put into practice; open government itself will not be a driving force to a prosperous society. 相似文献
