London elected a Muslim mayor in 2016, less than a year after Germany took the lead in welcoming Syrian refugees. What accounts, then, for political leaders’ public assertions of the death of multiculturalism and the resurgence of far-right parties? We examine the possibility that some areas of multicultural policy foster a sense of discrimination on the part of majority populations and reduce their sense of safety, putting pressure on political leaders for assurances and providing the impetus for populist political party agendas, even to the point of Brexit. Data from the Banting/Kymlicka Multiculturalism Policy Index project and from the European Social Survey allow us to explore the impact of specific areas of multicultural policy on those who identify as majority group members, ethnic minorities, and Muslims in fourteen European states. We provide a quantitative multivariate analysis of the influence of key areas of state-level multicultural policy on individuals’ sense of being in a group that is discriminated against, as well as their feelings of safety, satisfaction with life, and satisfaction with the national government. Background factors, including respondents’ education, are controlled. For each of the three groups of respondents, the article offers conclusions as to which areas of multicultural policy seem to contribute to the most adverse reactions. Our findings help to explain the backlash against multiculturalism and the shift in focus in European states toward “mainstreaming” integration programs. They also provide a contextual background for understanding the increasing sway of rightist party demands and cautions for the development of programs to counter violent extremism.  相似文献

Objectives

The present study provides an illustration of a statistical test of the Brantinghams’ theory about the formation of hotspots and the effects that nodes, paths, and environmental backcloth have on their development.

Methods

We used multilevel Poisson regression analysis to explain variation in the count of incidents at each address. Place-level proximity to nodes and paths was measured by using the Euclidian distance from each location to the closest carry-out liquor store, on-premises drinking establishment, and bus route. The broader environmental backcloth was represented by various census block-group characteristics, including density of commercial land use. A three-way place-level interaction as well as a cross-level interaction involving all four key independent variables were used to estimate the Brantinghams’ concept of the overlay of nodes, paths, and backcloth.

Results

The three-way interaction involving the distance to the closest on-premises liquor establishment, the distance to closest carry-out liquor facility, and the distance to the closest bus route was significantly and negatively related to place-level crime incidents. This three-way interaction had effects which varied across neighborhood contexts, with stronger negative effects on crime occurring in neighborhoods characterized by high levels of commercial density.

Conclusion

This study supported the notion of a multilevel theory of crime places and has implications for more effectively addressing crime. In particular, those places with multiple nodes and paths in their proximal environments and dense commercial land within their broader environments likely need additional crime prevention measures to get the same benefit relative to places with multiple nodes and paths in the proximal environments yet little commercial density within their broader environment.

Participants in the Open Working Group (OWG) on Sustainable Development Goals (SDGs) were reminded time and again that there is no model for the process to develop the SDGs. They resolved to not repeat the closed process used to develop the Millennium Development Goals, but the OWG began work when failures to reach consensus and fatigue with multilateral environmental negotiations dominated delegates’ minds, rather than examples of successfully negotiated outcomes. The OWG Co-Chairs were faced with the daunting task of guiding delegates’ efforts to develop a proposed set of crisp SDGs and targets that all could agree to, and thus, had to accomplish the following goals: (1) reduce delegation rigidity, both of individual Member States and within coalitions; (2) maximize the sense of participation, transparency, and ownership to get the most buy-in at the end; and (3) develop a sense of trust that would change the relationship between Member States. To do this, the OWG Co-Chairs broke the mold of UN multilateral negotiations that Member States and observers had become familiar with and created a different approach. This article examines how the OWG accomplished these goals and overcame the shortcomings of other multilateral negotiating processes on sustainable development to produce a widely supported consensus outcome at a time when governments have struggled to achieve agreement in many multilateral negotiation tracks.  相似文献

Psychological injuries, like physical injuries, may occur within the workplace. If those injuries are reported to be a result of a triggering event in the workplace, then a workers’ compensation (WC) claim may be filed by the individual. State WC and the federal WC systems have laws and rules in place to address workplace psychological injury claims. However, because each State has its own WC State laws as does the federal WC system, there is no current standardization in defining either psychological injury or in defining disability. This is because each system has its own definitions. A few States allow workplace psychological injury claims. Some States do not accept WC psychological injury claims. The remaining States recognize workplace psychological injuries but with specific limitations. The federal WC system allows WC psychological injury claims. There are problematic issues that occur in the State and federal WC systems. These issues are utilizing outdated terminology, employing outdated diagnostic criteria, and allowing documentation submission and professional opinion that does not comport with current professional standards of care. In addition, the need for a definitive answer to address causation is not always possible to address with regard to psychological injury. These types of issues introduce imprecision into the determination of psychological injuries. To address these concerns, the American Medical Association developed the Guides to the Evaluation of Permanent Impairment as a means to take a more scientific approach to the assessment of impairment. This stance was a move away from the poorly defined term, “disability”. The focus was on evaluating the individual’s functioning in terms of impairment. The AMA holds that this is a more objective method that provides a balance between clinical opinion and the utilization of a more scientific methodology that increased precision in the determination of psychological injury and purported impairment in functioning that may have resulted from the injury. The American Medical Association’s Guides to the Evaluation of Permanent Impairment are utilized by many States and the federal WC systems to assist in the evaluation of psychological impairment in functioning and in the WC claims process. Some States opt to use earlier editions of the Guides. Other States and the federal WC system require the usage of the most current edition of the Guides. A few States opt to forego the usage of the Guides altogether and develop State-specific guidelines. The complexities that arise within the WC systems as well as usage of the Guides to evaluate and assess psychological injury are explored as well as potential solutions to address the imprecision that occurs within the WC systems.  相似文献

A previous study suggested that small amounts of morphine are metabolically converted to hydromorphone. In the present study, morphine positive urine specimens obtained from a postmortem laboratory and a random urinalysis program were tested for morphine, codeine, hydromorphone, hydrocodone, oxymorphone, and oxycodone to assess the possibility that small amounts of hydromorphone are produced from the metabolism of morphine. The opioids were analyzed by gas chromatography-mass spectrometry as their respective trimethylsilyl derivatives following solid phase extraction. The limit of detection for hydromorphone was 5 ng/mL. A total of 73 morphine positive urine specimens were analyzed, with morphine concentrations ranging from 131 to 297,000 ng/mL. Hydromorphone was present at a concentration > or =5 ng/mL in 36 of these specimens at concentrations ranging from 0.02% to 12% of the morphine concentration. Hydrocodone was not detected in these specimens at the assay detection limit of 25 ng/mL. These results support earlier work suggesting that the detection of hydromorphone in urine specimens does not necessarily mean that exogenous hydromorphone or hydrocodone was used.  相似文献

Meta-analyses have suggested that sexual offender treatment (SOT) completion is associated with lowered sexual recidivism rates for convicted sexual offenders. The paucity of properly designed studies allows for the alternative explanation of less recidivism among treated samples as reflecting that lower risk offenders disproportionately self-select into treatment. A test of the "self-selection explanation" can occur by investigating treatment effect on known high-risk offenders. Psychopathy correlates with increased sexual recidivism risk, such that an exploration of the SOT effect on psychopathic offenders could clarify the accuracy of the self-selection hypothesis. Additionally, the debated degree to which psychopaths are treatable might obtain clarification by a research review. This article examines empirical findings concerning the effectiveness of SOT for psychopathic sexual offenders. Ten studies were found to meet the minimal quality standards used, stemming from only four data sources. Shortcomings of existing research precluded clear conclusions, though trends in the data are delineated.  相似文献

Teachers at school are typically considered as handlers or guardians of students and managers of classrooms—in roles that foster learning and protect students from harm. Thus, relatively little research attention is given to identifying the risk factors for teacher victimization in comparison with the great deal of work addressing the correlates of student victimization at school. The present study fills this gap in the literature on school violence by examining the individual- and school-level predictors of teacher victimization. The authors’ analysis is framed using a multilevel opportunity theoretical approach, incorporating measures of teacher activities, self-protection, teacher attributes that suggest target vulnerability and target antagonism, school-level norms supportive of delinquency, and school-level guardianship. These various risk and protective factors are examined using hierarchical negative binomial regression models with data from over 4,100 teachers in 98 schools in Kentucky.  相似文献
