The Iraqi Insurgency (2003–2011) has commonly been characterized as demonstrating the tendency for violence to cluster and diffuse at the local level. Recent research has demonstrated that insurgent attacks in Iraq cluster in time and space in a manner similar to that observed for the spread of a disease. The current study employs a variety of approaches common to the scientific study of criminal activities to advance our understanding of the correlates of observed patterns of the incidence and contagion of insurgent attacks. We hypothesize that the precise patterns will vary from one place to another, but that more attacks will occur in areas that are heavily populated, where coalition forces are active, and along road networks. To test these hypotheses, we use a fishnet to build a geographical model of Baghdad that disaggregates the city into more than 3000 grid cell locations. A number of logistic regression models with spatial and temporal lags are employed to explore patterns of local escalation and diffusion. These models demonstrate the validity of arguments under each of three models but suggest, overall, that risk heterogeneity arguments provide the most compelling and consistent account of the location of insurgency. In particular, the results demonstrate that violence is most likely at locations with greater population levels, higher density of roads, and military garrisons. 相似文献

Toxicology and characteristics of deaths involving zolpidem in new South wales, australia 2001-2010*
Abstract: All cases presenting to the New South Wales Department of Forensic Medicine between January 1, 2001 and September 31, 2010 in which zolpidem was detected, were retrieved. A total of 91 cases were identified. The mean age was 49.4 years, 65.9% were male, and 61.5% were suicides. Zolpidem was a factor contributing to death in 35 (37.3%) cases, of which 31 (34.1%) involved zolpidem toxicity. The median blood zolpidem concentration was 0.20 mg/L (range 0.05–3.50 mg/L), with no significant gender difference. Drug toxicity cases involving zolpidem had significantly higher median blood zolpidem concentrations than other cases (0.50 vs. 0.10 mg/L). In 83.5% of cases, psychoactive substances other than zolpidem were detected, most commonly antidepressants (46.2%), benzodiazepines (35.2%), opioids (26.4%), and alcohol (39.6%). In summary, zolpidem was a factor contributing to death in a large proportion of cases, predominately involving drug toxicity and suicide. 相似文献

This study examines the impact organizational stressors have on police performance. Evidence on police stress is mixed whether or not the nature of police work is inherently stressful. A growing body of research suggests police officers are no more stressed than other groups and police work is not especially stressful. Instead, organizational stressors may be a greater source of stress due to various structural arrangements, policies and practices. This cross-sectional study uses survey data (n = 461) from two large urban police departments in Michigan and New Jersey. Multiple regression predicts lower performance as perceived stressors increase and paired-sample t test reveals organizational stressors are significantly different from operational stressors. The results imply the need for structural changes in police organizations. Future research should examine police performance in smaller and mid-size police agencies as well as suburban and rural agencies and widen the participant pool to include superior officers and civilian personnel. 相似文献

We investigate whether politicians whose family relatives previously served in parliament and cabinet enjoy a competitive “legacy advantage” in progressing from the backbenches to cabinet. This advantage may stem from two potential mechanisms: a direct effect attributable to the informational advantages of legacies or an indirect effect that operates through greater electoral strength. We evaluate the relative contribution of each mechanism using candidate‐level data from Irish parliamentary elections and cabinets from 1944 to 2016. Our results reveal that politicians with a family history in cabinet do enjoy an advantage in cabinet selection, and that this advantage cannot be attributed simply to greater electoral popularity. 1 相似文献

In some Latin American nations, policy change occurs frequently, while in others it is stable, less prone to shifts with the prevailing political climate or shocks. The conditions under which institutional rules and the powers of key actors influence the capacity for governance vary, and this variation is seldom addressed in the literature. This project examines the effects of the interactions between key policymakers (the executive and the legislature) in Latin America on policy stability across different institutional frameworks. Countries with simultaneously strong executives and weak legislatures are shown to have unstable policy environments, as are countries with a history of unified government and, to a lesser extent, candidate‐centered electoral systems. 相似文献
