Homicide-suicide forms a distinct form of homicide. An analysis of cases in the Yorkshire and Humberside region of England between 1991 and 2005 revealed 37 episodes with 42 victims. Previous studies have shown a high rate of use of firearms. Over the last 2 decades firearms legislation has become more restrictive. In this study all assailants were male, mean age 46.8 years. The commonest method of homicide was strangulation (36%) with 16% killed by firearms. This is a reduction compared with a previous study in the same region. All killers who shot their victims killed themselves with firearms. There were no multiple killings with firearms in this study and no stranger killings. Hanging was the commonest method of suicide. During the same period the use of firearms as a method of homicide increased in England and Wales with handguns, the most common weapon. Nationally, suicide after homicide has remained at a similar rate over the half century and is an uncommon phenomenon. Firearms use remains low in both homicide and homicide-suicide episodes in England, and further analysis is required to determine changes in patterns of killing. 相似文献

This research investigates low religiosity as a predictor of violent victimization. The theoretical framework the authors present here posits that religiosity should help structure daily activities in such a way as to (a) limit exposure to offenders by encouraging contact with peers who are less deviant, (b) lessen one's target suitability by inhibiting grievance-causing delinquent activity, and (c) enhance guardianship by fostering stronger bonds with parents and school. Thus, although researchers expect religion to be a bivariate predictor of violent victimization, its influence should be indirect. The authors investigate these claims using two waves from the public-use version of the National Longitudinal Study of Adolescent Health (Add Health). The results indicate that religiosity is a correlate of violent victimization. Consistent with these theoretical claims, the effect of religiosity is not direct, but instead occurs indirectly primarily through its influence on self-reported delinquency and peer deviance. 相似文献

In this article, we model the effect of foreign policy attitudes on both vote choice and casualty tolerance, using survey
data collected during the 2004 election. We show that prospective judgments of the likelihood of success in Iraq and retrospective
judgments of whether the war in Iraq was right are significant determinants of both vote choice and casualty tolerance. The
prospective judgment of success is key in predicting casualty tolerance, while retrospective judgment of whether the war was
right takes precedence in determining vote choice. In addition, there is an important interaction between the two variables,
so the effect of one is conditional on the value of the other. We believe this is compelling evidence that foreign policy
matters, and that it matters in reasonable ways.

Prediction markets have drawn considerable attention in recent years as a tool for forecasting elections. But how accurate are they? Do they outperform the polls, as some scholars argue? Do prices in election markets carry information beyond the horserace in the latest polls? This paper assesses the accuracy of US presidential election betting markets in years before and after opinion polling was introduced. Our results are provocative. First, we find that market prices are far better predictors in the period without polls than when polls were available. Second, we find that market prices of the pre-poll era predicted elections almost on par with polls following the introduction of scientific polling. Finally, when we have both market prices and polls, prices add nothing to election prediction beyond polls. To be sure, early election markets were (surprisingly) good at extracting campaign information without scientific polling to guide them. For more recent markets, candidate prices largely follow the polls. 相似文献

Why do some governments implement more sustainability practices than others? Based on a national survey of U.S. cities, this article finds moderate levels of sustainability efforts and capacity in U.S. cities; about one‐third of the sustainability practices identified in this article have been implemented. The authors conclude that, first, capacity building is a useful conceptual focus for understanding sustainability implementation in U.S. cities. Capacity building involves developing technical and financial support and increasing managerial execution. Second, sustainability is strongly associated with managerial capacity, which includes establishing sustainability goals, incorporating goals in operations, and developing a supportive infrastructure. Third, getting stakeholders involved furthers the capacity for sustaining sustainability efforts. Citizen involvement is strongly associated with securing financial support for sustainability. 相似文献

The economy was a major issue in Germany’s 2009 election. The global economic crisis did not spare Germany, whose economy is tightly integrated into the global economy. So when the German economy experienced a historical shock, did voters connect their views of the economy with their vote choice? Or did they, as some research has suggested, recognize Germany’s dependence on global markets and cut the government slack, especially when the government consists of the country’s two major parties? Using pre- and post-election panel surveys from the German Longitudinal Election Study (GLES), we investigate the weight that voters gave to the economy, relative to other considerations, when casting their ballot and whether governing parties were disproportionately judged based on the state of the economy. 相似文献

Social learning theory is one of the most prominent general theories of crime. Yet recent research has called into question its applicability to all offenders. Specifically, the influence of antisocial peers has been found to exert a stronger effect among those individuals evincing higher levels of criminal propensity (deemed social amplification), whereas other components of the theory have either not been shown to interact with criminal propensity or not been tested. This study examines several social learning theory components to determine whether its influence is dependent on an individual's level of self-control. Results suggest little support for the social amplification hypothesis as the components of social learning theory were found to operate similarly across individuals regardless one's level of self-control. Implications for criminological theory are discussed. 相似文献

Research generally supports the use of the Personality Assessment Inventory (PAI; Morey 1991) to detect feigned PTSD, although this support has been somewhat mixed. There is also evidence that coaching individuals on the presence of PAI validity indicators may not affect their ability to avoid detection as feigners (Bagby et al. in Journal of Personality Assessment 78:69–86, 2002), although this question has not been specifically addressed with regard to PTSD. Additionally, a new PAI validity indicator, the Negative Distortion Scale (NDS), was developed that may have utility in detecting feigned PTSD, but this has not been tested. The purpose of this study was to further test the operating characteristics of the PAI validity indicators to detect feigned PTSD among naïve and coached respondents and to examine the newly developed NDS for this purpose. Individuals with genuine PTSD were compared to individuals instructed to feign PTSD on PAI validity indicators. Results suggest that: (a) coaching had minimal influence on the ability of the PAI to detect feigned PTSD, (b) the PAI validity indicators all significantly differentiated genuine from feigned PTSD, and (c) the NIM and NDS indicators were particularly effective for detecting feigned PTSD. 相似文献
