This study examines the psychological impact of viewing disturbing media on investigators engaged in computer forensics work.
Twenty-eight federal law enforcement personnel who investigate Internet child pornography cases completed measures of secondary
traumatic stress disorder (STSD) and burnout. Substantial percentages of investigators reported poor psychological well-being.
Greater exposure to disturbing media was related to higher levels of STSD and cynicism. STSD and burnout scores were related
to increased protectiveness of family, reliance on co-workers, general distrust, and turnover intentions. On a positive note,
investigators scored high in professional efficacy, indicating they feel their work makes a difference. Furthermore, personnel
with supportive relationships scored lower on both STSD and burnout. 相似文献

Boston, like many other major U.S. cities, experienced an epidemic of gun violence during the late 1980s and early 1990s that
was followed by a sudden large downturn in gun violence in the mid 1990s. The gun violence drop continued until the early
part of the new millennium. Recent advances in criminological research suggest that there is significant clustering of crime
in micro places, or “hot spots,” that generate a disproportionate amount of criminal events in a city. In this paper, we use
growth curve regression models to uncover distinctive developmental trends in gun assault incidents at street segments and
intersections in Boston over a 29-year period. We find that Boston gun violence is intensely concentrated at a small number
of street segments and intersections rather than spread evenly across the urban landscape between 1980 and 2008. Gun violence
trends at these high-activity micro places follow two general trajectories: stable concentrations of gun assaults incidents
over time and volatile concentrations of gun assault incidents over time. Micro places with volatile trajectories represent
less than 3% of street segments and intersections, generate more than half of all gun violence incidents, and seem to be the
primary drivers of overall gun violence trends in Boston. Our findings suggest that the urban gun violence epidemic, and sudden
downturn in urban gun violence in the late 1990s, may be best understood by examining highly volatile micro-level trends at
a relatively small number of places in urban environments. 相似文献

This case note examines the implications of the House of Lords decision to order the DPP to issue offence specific guidelines allowing those contemplating assisting terminally ill persons to commit suicide to know the risk they face of prosecution under section 2(1) of the Suicide Act 1961. On the assumption that these guidelines will be law, and binding upon the DPP as well as the CPS, does this represent a change in the law, or a situation in which it may be unlawful to enforce the law, or even generate a legal right of disobedience to law? 相似文献

This study asked whether latent class modeling methods and multiple ratings of the same cases might permit quantification
of the accuracy of forensic assessments. Five evaluators examined 156 redacted court reports concerning criminal defendants
who had undergone hospitalization for evaluation or restoration of their adjudicative competence. Evaluators rated each defendant’s
Dusky-defined competence to stand trial on a five-point scale as well as each defendant’s understanding of, appreciation of, and
reasoning about criminal proceedings. Having multiple ratings per defendant made it possible to estimate accuracy parameters
using maximum likelihood and Bayesian approaches, despite the absence of any “gold standard” for the defendants’ true competence
status. Evaluators appeared to be very accurate, though this finding should be viewed with caution. 相似文献

We present a case from the Johannesburg General Hospital of a zone II low-velocity penetrating neck injury with involvement of the ipsilateral subclavian artery. When the "bullet" was retrieved, it was noted not to be an actual bullet but rather a cartridge casing. We speculate that this injury represents one of several possible misfiring scenarios from a homemade firearm. Injuries from homemade firearms are infrequent in the literature, and only one other similar case of a cartridge casing causing a penetrating injury was found. A brief review of homemade handheld firearms is offered. 相似文献

Israel's enactment of national health insurance was clearly a breakthrough. However, other aspects of reform that were supposed to be implemented simultaneously were stymied, in particular, the conversion of government hospitals to independent trusts and removing the Ministry of Health from the direct provision of services such as mental health and long-term care. This article explores how punctuated equilibrium and path dependency coexist in the Israeli case. In doing so, it examines the relevance of concepts provided by various theories of social and institutional change. Aside from path dependency and punctuated equilibrium, we discuss other notions derived from related theories, such as political leadership and the role of ideas. Applying these theories to the Israeli case helps better understand the coexistence of punctuated equilibrium and path dependency. 相似文献

This paper explains why and how a technology transfer revolution is taking place in Saudi Arabia to meet the mandate that
Saudi Arabia become globally competitive as a knowledge-based innovative economy. The paper explains and identifies the new
policies and institutions that have been introduced and developed to facilitate technology transfer and knowledge spillovers
from the universities for commercialization and ultimately innovative activity and economic growth. The paper finds that a
technology transfer revolution in Saudi Arabia is taking place, with the goal of leapfrogging from the factor-based stage
of economic development to the innovation-based stage of economic development, while bypassing the intermediary efficiency-based
stage of economic development. 相似文献

The behavioral work context in which members of groups interact with each other is crucial for facilitating knowledge exchange and combination (Nonaka in Great minds in management: the process of theory development, Oxford University Press, Oxford 2005; Nonaka et al. in Long Range Plan 33:5–34, 2000). Yet little is known about the ways leaders, by signaling expectations and exhibiting supportive behaviors, facilitate such a behavioral context, which may then enhance performance. This study aims to contribute to the literature by examining how leader expectations and supportive behaviors facilitate behavioral integration and enhance the performance of work groups engaging in the development of advanced technological products. Data collected from management teams of 102 work groups indicate significant and positive relationships between: (1) leader expectations and leader supportive behaviors, (2) leader supportive behaviors and group behavioral integration, and (3) behavioral integration and group performance. In addition, the results indicate that leader supportive behaviors partially mediate the relationship between leader expectations and group behavioral integration, and the latter partially mediates the link between leader supportive behaviors and group performance. No significant link was found between leader expectations and group performance. In so doing, this study contributes to research on the way leaders, by shaping a behavioral context, facilitate knowledge exchange and combination, thereby enhancing group performance. 相似文献
