Bystanders killed by bullets not specifically intended for them have long been a very small part of the homicide problem. But the frequency of press accounts of such killings and woundings has apparently increased nationally in recent years. To test this impression, we compiled all shootings of bystanders hit at random and reported in the published indexes of theNew York Times, theLos Angeles Times, and theWashington Post for 1977–1988, as well as a key word computer search of stories in theBoston Globe. We found a rapid increase in both bystander woundings and killings since 1985 in all four cities. The base rate was quite low, and total bystander deaths appear to comprise less than 1% of all homicides in these cities. Nonetheless, the numbers were large enough to show that most bystanders reported shot in New York and Los Angeles are victims of random shootings into crowds, rather than single stray bullets striking a lone individual mushroom. The reverse was true in Boston and Washington, with the effect of much lower rates of bystanders reported shot in those cities.  相似文献

Technology has had a profound and immeasurable impact on our lives, our work and our social concerns. In perhaps what could be considered unique and completely unprecedented, technology has had a revolutionary impact on the way our world now searches for its missing children. State-of-the-art computer technology has made it possible to show the public what long-term missing children might look like today. Data mining gives law enforcement agencies the personal information they need to track wanted abductors. And, of course, with the advent of the Internet, the world has become a much smaller place for perpetrators to hide.  相似文献

The effect of pretrial publicity (PTP) on juror verdicts was examined through a meta-analysis of 44 empirical tests representing 5,755 subjects. In support of the hypothesis, subjects exposed to negative PTP were significantly more likely to judge the defendant guilty compared to subjects exposed to less or no negative PTP. Greater effect sizes were produced in studies which included a pretrial verdict assessment, use of the potential juror pool as subjects, multiple points of negative information included in the PTP, real PTP, crimes of murder, sexual abuse, or drugs, and greater length of time between PTP exposure and judgment. The effect was attenuated with student subjects, use of general rather than specific PTP information, certain types of PTP content, a post-trial predeliberation verdict, and specific types of crimes. Implications of these results are discussed, along with possible mechanisms that underlie the PTP effect.  相似文献

Currently little research exists examining self-mutilation (SM) in community samples of adolescents, despite tentative findings suggesting that self-harming behaviors, including SM may be increasing. The present study provides a comprehensive review of previous literature on the frequency of SM as well as preliminary epidemiological data concerning the frequency of SM in a community sample of high schools students. The relationship between SM, anxiety, and depressive symptomatology was also assessed. Four hundred and forty students from two schools, an urban and a suburban high school, were given a screening measure designed to assess for SM. Students who indicated that they hurt themselves on purpose also participated in a follow-up interview. Based on interviews it was found that 13.9% of all students reported having engaged in SM behavior at some time. Girls reported significantly higher rates of SM than did boys (64 vs. 36%, respectively). Self-cutting was found to be the most common type of SM, followed by self-hitting, pinching, scratching, and biting. Finally, students who self-mutilate reported significantly more anxiety and depressive symptomatology than students who did not self-mutilate. Results are also presented concerning demographic information and patterns of SM behavior.  相似文献

In 1959, the four largest political parties in Switzerland’s Federal Assembly established a broad coalition government with a specific allocation of the seven cabinet seats among them. This assignment continued unaltered for 44 years up to 1999. It is, therefore, phrased the ‘Magic Formula’. The underlying political paradigm appears to be essentially egalitarian, with a Rawlsian concern for minorities. We thus ask whether the Magic Formula can be implemented by the nucleolus of a weighted voting game for the Swiss government. We provide results over real-valued and integer-valued imputation sets, and for all regular election periods from 1959 to date. It turns out that the Magic Formula is contained in eight out of 11 nucleoli over integer domains between 1959 and 1999, and that it comes very close to the nucleolus in two of the three remaining cases. The game solution likewise predicts in part a major modification of the Magic Formula adopted in 2003.  相似文献

The number of private prisons run by corporate security businesses has increased rapidly throughout the past two decades. There has been a parallel increase in literature, both pro and con, comparing the efficiency and effectiveness of private and public prisons; however, private prison staff has been largely ignored. OLS regression analysis of a survey of 160 employees at a Midwestern private prison facility showed that the job characteristics of job stress, supervision, and job variety were far more important than personal characteristics of race/ethnicity, gender, age, tenure, education and position in influencing staff job satisfaction and organizational commitment. Specifically, job stress had the largest impact on job satisfaction, while quality of supervision had the greatest impact on organizational commitment.  相似文献
