Research Summary
Our understanding of how immigration enforcement impacts crime has been informed exclusively by data from police crime statistics. This study complements existing research by using longitudinal multilevel data from the National Crime Victimization Survey for 2005–2014 to simultaneously assess the impact of the three predominant immigration policies that have been implemented in local communities. The results indicate that the activation of Secure Communities and 287(g) task force agreements significantly increased violent victimization risk among Latinos, whereas they showed no evident impact on victimization risk among non-Latino Whites and Blacks. The activation of 287(g) jail enforcement agreements and anti-detainer policies had no significant impact on violent victimization risk during the period.Policy Implications
Contrary to their stated purpose of enhancing public safety, our results show that the Secure Communities program and 287(g) task force agreements did not reduce crime, but instead eroded security in U.S. communities by increasing the likelihood that Latinos experienced violent victimization. These results support the Federal government's ending of 287(g) task force agreements and its more recent move to end the Secure Communities program. Additionally, the results of our study add to the evidence challenging claims that anti-detainer policies pose a threat to violence risk. 相似文献762.
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

The success of any organization usually rests on the shoulders of its employees. As such, voluntary personnel turnover presents administrative challenges that have substantial and far reaching effects. Understanding the factors that lead to staff turnover intentions can assist organizational leaders in possibly altering the work environment to address employee concerns. Among correctional organizations, the few studies that have been conducted on turnover intent have focused, as most correctional research in general, on prisons. The exclusion of jail turnover intent is puzzling given the unique challenges that jail staff face. The current study attempted to fill this empirical void by using survey data to examine the antecedents (i.e., personal characteristics, perceptions of the work environment, and job attitudes) of turnover intent among staff at a large southern jail. Based on a multivariate analysis, the most powerful predictors of jail staff turnover intent were job attitudes (i.e., job involvement, job satisfaction, and organizational commitment). The findings suggested that administrators should concentrate on improving the work environment to boost employee job involvement, job satisfaction, and organizational commitment. 相似文献

Much of the literature concerning sexual minorities describes various forms of social mistreatment, alongside the psychological ill effects of minority stress. However, bisexual individuals are often described as having additional burdens compared with other sexual minorities. We conceptualise the collective of these social problems as ‘bisexual burden’, and examine for it through the lived experiences of 15 openly bisexual girls (aged 16–17) from sixth form colleges throughout the UK. We show that, among this cohort, decreasing cultural stigma attached to sexual minorities results in participants being more accepted by their heterosexual and gay peers, compared to previous literature, mostly without the negative components of bisexual burden. We find that when mistreatment does occur, it does so immediately after she comes out; however, this diminishes quickly due to the cultural unacceptability of homo/biphobia in these settings. 相似文献

Extending prior research regarding victim injury during sexual assault, the current study employed mixed-methods sequential explanatory research design to identify predictors of victim injury and victim death in 361 attempted and completed sexual assaults committed by 72 repeat sex offenders who assaulted strangers. Results from multinomial path analysis indicated that being female and offender coercion increased the likelihood of victim resistance, which in turn elevated the likelihood of victim injury. Divergent from the predictors of victim injury, the risk of victim death increased with victim age, offender alcohol use, and offender weapon possession. Exploratory analyses suggest that certain weapons resulted in higher probability of victim injury or victim death within the context of victim resistance. Exploratory analysis of qualitative data indicated that crime event order was not uniform—in some cases victim resistance preceded victim injury and in some assaults victim injury occurred prior to or was unrelated to victim resistance. The study findings highlight the need for further investigation of victim survival strategies when offenders possess different types of weapons. 相似文献

This article addresses the puzzle of electoral support for corrupt politicians in emerging democracies by examining citizens’ varying attitudes toward political corruption. We make an important theoretical distinction between perceptions of and tolerance for corruption, and argue that these different attitudes vary across individuals depending on whether they are political insiders or outsiders. We test our theory using Afrobarometer survey data from 18 sub‐Saharan African countries and find that individuals included within clientelistic networks simultaneously perceive corruption as ubiquitous and are more tolerant of malfeasance. Meanwhile, those individuals with partisan or ethnic ties to the incumbent are less likely to consider corruption as widespread. Finally, we explore whether variation in attitudes toward corruption influences citizens’ voting behavior, and find that insiders are less likely to “vote the rascals out.” 相似文献

Due to the shot-to-shot variability in tool mark reproduction on fired cartridge cases, a method of replication is needed for the creation of training and testing sets. Double-casting is one method that has been used for this application, but the accuracy and variability of this method needs to be characterized. Three firearms were used to fire 25 cartridges each to create the master cartridge cases. The double-casting method consists of creating a silicone mold of the master cartridge case. A plastic resin mix is then poured into the mold to create the double-cast reproduction. Fifteen double-casts of each of the 75 fired cartridge cases were created across different silicone molds to analyze within- and between-mold variability. The master cartridge cases and double-casts were scanned with a confocal microscope (Sensofar® S neox) to create three-dimensional representations of the surfaces. Two similarity metrics were used for the objective comparison of the double-casts to their master cartridge cases: the areal correlation coefficient (ACCFMAX) and the number of congruent matching cells (CMC). The ACCFMAX and CMC data, along with visual examinations, showed that the double-casting method produces accurate reproductions. Within-mold variability was found to be minimal, and between-mold variability was low. These results illustrate that double-casting can be applied for training and testing purposes. 相似文献
