In examining constructive responses to the problems caused by violent ethnic conflict a distinction is often made between the ‘management’ and ‘resolution’ approaches. Indeed, they are often defined so as to make them incompatible with each other. The basic assumptions upon which the differences between these two approaches are based are analysed, and the weaknesses of each are explored. Finally, the assumption of basic incompatibility is questioned, because it is generally unhelpful in promoting conflict resolution; and an attempt is made to show how the two approaches can be combined by introducing the concept of peace‐keeping (management) and peace‐making and peace‐building (resolution).  相似文献

This article challenges the almost universal consensus that post–Cold War neoconservative foreign policy has been characterised by the objective of “exporting democracy” abroad for strategic or moral reasons or both. Instead, the article contends that the touchstone of neoconservatism was the attempt to preserve America's so-called “unipolar moment”—its apparent position as the single pole of power in every region of the world. Moving beyond the abstract and grandiose rhetoric employed by many neocons, the article points out that neocons made a distinction between the respective uses of military and non-military power, arguing that the former should be reserved only for situations where strategic interests were at stake rather than for the sake of ideals. The article goes on to argue that this focus on strategic interests facilitated a close alliance with other conservative nationalists who were also dedicated to maintaining America's position as the single pole of world power. Thus neoconservatism should be analysed and evaluated—by both conservatives and liberal interventionists alike—on the basis that it was a strategy dedicated primarily to preserving American unipolarity, not to the promotion of ideals.  相似文献

While the field of research related to game wardens is growing, there is almost no empirical research related to game wardens and the use of force. This study adds to this virtually non-existent, but important field. The data come from 261 self-reports from the Florida Fish and Wildlife Conservation Commission Division of Law Enforcement from 2002 to 2009. The incidents were analyzed based on following factors: the time of the day, the day of the week, the season of the year, and the activity the suspect was engaged in prior to the contact. The results demonstrated the majority of use of force incidents occurred from 6:01 p.m. to midnight, during Fridays, Saturdays, Sundays or national holidays, during the summer, and when the suspect was participating in a non-hunting or fishing activity. While this research addresses a missing component of the literature, the generalizeability of the findings are limited. Still, additional research is needed in this area before more firm conclusions can be reached.  相似文献

George W. Bush has claimed that the latest intelligence estimates single out Iran, Iraq, and North Korea as an ‘axis of evil’ fomenting terrorism and weapons of mass destruction. However, the intelligence itself demonstrates that this concept has been largely manufactured and the CIA bypassed in favor of a pre-existing political consensus among right-wing Republicans. In reality, the ‘axis’ serves to perpetuate an American ‘preponderance of power’. It justifies specific policies which had already been decided before Bush came to power and which now have popular acceptance through their association with the successful war on terrorism.  相似文献

Purpose

Despite the peer delinquency measurement debate having profound implications for research, looming questions remain about the validity of various forms of peer delinquency operationalizations. This study examines whether perceptions of peer delinquency form identical latent constructs to both respondent and peer self-reported delinquency.

Methods

Using a dyadic dataset of friendship pairs, confirmatory factor analysis and model comparison tests are used to determine the degree of similarity between perceptions of peer delinquency, respondent self-reported delinquency, and peer self-reported delinquency.

Results

Peer self-reports and respondent perceptions of peer delinquency load on unique constructs across a number of different behaviors. For most behaviors, respondent perceptions of peer delinquency and respondent self-reports load on separate constructs. Results further indicate that respondent and peer self-reported delinquency are separate latent constructs. Finally, the strength of the association between respondent and peer delinquency is substantively smaller in magnitude, by as much as a factor of three in some instances, when peer delinquency is measured via peer self-reports in place of respondent perceptions.

Conclusions

Reports of peer delinquency provided directly from peers demonstrate strong discriminant validity in relation to self-reported delinquency, while perceptions of peer delinquency demonstrate poorer discriminant validity, particularly for theft and violence constructs.  相似文献

Since the development of the striagraph, various attempts have been made to enhance forensic investigation through the use of measuring and imaging equipment. This study describes the development of a prototype system employing an easy‐to‐use software interface designed to provide forensic examiners with the ability to measure topography of a toolmarked surface and then conduct various comparisons using a statistical algorithm. Acquisition of the data is carried out using a portable 3D optical profilometer, and comparison of the resulting data files is made using software named “MANTIS” (Mark and Tool Inspection Suite). The system has been tested on laboratory‐produced markings that include fully striated marks (e.g., screwdriver markings), quasistriated markings produced by shear‐cut pliers, impression marks left by chisels, rifling marks on bullets, and cut marks produced by knives. Using the system, an examiner has the potential to (i) visually compare two toolmarked surfaces in a manner similar to a comparison microscope and (ii) use the quantitative information embedded within the acquired data to obtain an objective statistical comparison of the data files. This study shows that, based on the results from laboratory samples, the system has great potential for aiding examiners in conducting comparisons of toolmarks.  相似文献

Intimate partner violence (IPV) is overrepresented among men in substance use treatment. Individuals who relapse following substance use treatment report greater IPV perpetration relative to individuals who remain remitted. In addition, distress tolerance has been shown to be an important treatment target in substance use treatment, with distress tolerance predicting relapse following treatment. However, we are unaware of any research that has examined the relationship between distress tolerance and IPV among men in substance use treatment, which may hold important treatment implications. The current study therefore examined this relationship in a sample of men in substance use treatment (N = 138). Results demonstrated that distress tolerance was negatively associated with physical and psychological IPV perpetration. After controlling for age and substance use and problems, distress tolerance remained associated with psychological, but not physical, IPV perpetration. These findings suggest that distress tolerance may be an important component of treatments for IPV, particularly for psychological aggression. Substance use treatment programs that target distress tolerance may concurrently reduce the risk for relapse to substance use and IPV perpetration.  相似文献

A retrospective review of 406 suicidal gunshot wounds to the head, investigated at the Medico-Legal Laboratory of Pretoria, between 1997 and 2000 was performed. Fifty-seven percent of fatal suicidal firearm injury to the head occurred in the 21- to 40-year age range in both male and female victims. Eighty-two percent of all these victims of suicidal firearm fatalities to the head were male. Of the 406 cases, 63% were white, 31% were black, and 6% were of mixed ethnic and/or Asian decent. There was a slight increase in incidence around spring and autumn. Handguns were used in the majority of cases with shoulder weapons being used in 18 of the 406 cases. Ninety-two percent of the suicidal gunshot wounds to the head occurred indoors. A positive blood alcohol concentration was seen in 40% of cases. Of those examined, 81% were contact gunshot wounds. The trajectory was upward in 51% of cases and horizontal in 24% of cases. The right temple was the most common entrance gunshot wound site. Findings are in keeping with previously published literature.  相似文献

Psychiatric advance directives (PADs) statutes presume competence to complete these documents, but the range and dimensions of decisional competence among people who actually complete PADs is unknown. This study examines clinical and neuropsychological correlates of performance on a measure to assess competence to complete PADs and investigates the effects of a facilitated PAD intervention on decisional capacity. N=469 adults with psychotic disorders were interviewed at baseline and then randomly assigned to either a control group in which they received written materials about PADs or to an intervention group in which they were offered an opportunity to meet individually with a trained facilitator to create a PAD. At baseline, domains on the Decisional Competence Assessment Tool for PADs (DCAT-PAD) were most strongly associated with IQ, verbal memory, abstract thinking, and psychiatric symptoms. At one-month follow-up, participants in the intervention group showed more improvement on the DCAT-PAD than controls, particularly among participants with pre-morbid IQ estimates below the median of 100. The results suggest that PAD facilitation is an effective method to boost competence of cognitively-impaired clients to write PADs and make treatment decisions within PADs, thereby maximizing the chances their advance directives will be valid.  相似文献

Parents and parenting practices are often implicated as predictors of early childhood offending in criminological research, but little is known about the role of parents in adulthood in promoting or inhibiting criminal behavior. As juveniles mature into adult roles, parents also continue to mature and interact with their children in numerous roles throughout the life course. Unlike peers and romantic partners, parents are not easily discarded. Adults who have built a good foundation with their parents, then, possess additional social capital that has the potential to better adult life course outcomes, including criminal behavior. Social bonds formed within romantic relationships and stable employment have been the dominant factors identified within criminological literature in promoting criminal desistance, but in today's society with high rates of divorce and an unstable low-skilled job market, parents of origin may be an important stabilizing force in the lives of adults, particularly those lacking other conventional bonds. Using three waves of data from the Ohio Lifecourse Study, a project that spans some twenty-one years, the findings showed that strong relationships with parents are a significant predictor of criminal desistance for adult children, mainly through the emotional benefits these relationships have for the adult children. Furthermore, the data revealed that the adult child-parent relationship is a stronger predictor of desistance among the subjects with poor romantic relationship bonds. Implications for the life course theory are discussed.  相似文献
