Abstract

Utilizing a rational‐actor policymaker model, this paper presents the necessary and sufficient conditions that must be satisfied for the formation of a transnational antiterrorist institution. Such an institution would tie together nations in their struggle against international terrorism. In particular, these institutions could provide crisis management, preemptive strikes, and retaliatory strikes. After analyzing the obstacles to the formation of such institutions, we present a specific proposal for a transnational commando unit. We chose the parameters of the proposed institution so as to maximize the likelihood of initial formation. In addition, we discuss how the transnational commando unit could, if properly designed, surmount the obstacles to formation. As terrorist groups increase their cooperation and stage incidents of a transnational kind, nations will have to turn to such institutions to increase the effectiveness of commando units, eliminate safe havens, and share intelligence. Although our proposal is more modest than those often put forth, once formed, our institution could evolve over time.  相似文献

Recent literature has suggested that measures of risk and protective factorsfor delinquency and substance use are not equally reliable or valid acrossgender and ethnic groups and has recommended differentiated programming andculturally specific evaluation methods. Three data sets containing up tofive ethnic groups were used to determine the degree to which risk andprotective factors are equally reliable and valid predictors of drug use anddelinquency across gender and ethnic groups. Congeneric measurement modelsand structural equation models were evaluated to determine if the factorstructures for these measures and their covariances with measures of druguse and delinquency were equivalent across gender and ethnic groups. Half ofthe risk and protective factors included in this analysis were found to beequally reliable across gender and ethnic groups. When controlling forreliability differences, all of the risk and protective factors were foundto predict both drug use and delinquncy for all gender and ethnic groups. Interms of the magnitude of these associations, no substantive differenceswere found in the validity of risk and protective factors for drug use anddelinquency. Differences in the validity of risk and protective factors weremore prevalent for delinquency than for drug use. However, all differenceswere substantively trivial. We conclude that measures of prevention programeffectiveness are invariant across gender and ethnic groups.  相似文献

Multiracial youth are thought to be more vulnerable to peer-related risk factors than are single-race youth. However, there have been surprisingly few well-designed studies on this topic. This study empirically investigated the extent to which multiracial youth are at higher risk for peer influenced problem behavior. Data are from a representative and longitudinal sample of youth from Washington State (N?=?1,760, mean age?=?14.13, 50.9% girls). Of those in the sample, 225 youth self-identified as multiracial (12.8%), 1,259 as White (71.5%), 152 as Latino (8.6%), and 124 as Asian American (7.1%). Results show that multiracial youth have higher rates of violence and alcohol use than Whites and more marijuana use than Asian Americans. Higher levels of socioeconomic disadvantage and single-parent family status partly explained the higher rates of problem behaviors among multiracial youth. Peer risk factors of substance-using or antisocial friends were higher for multiracial youth than Whites, even after socioeconomic variables were accounted for, demonstrating a higher rate of peer risks among multiracial youth. The number of substance-using friends was the most consistently significant correlate and predictor of problems and was highest among multiracial youth. However, interaction tests did not provide consistent evidence of a stronger influence of peer risks among multiracial youth. Findings underscore the importance of a differentiated understanding of vulnerability in order to better target prevention and intervention efforts as well as the need for further research that can help identify and explain the unique experiences and vulnerabilities of multiracial youth.  相似文献

Electronic social communication has provided a new context for children to bully and harass their peers and it is clear that cyberbullying is a growing public health concern in the US and abroad. The present study examined individual and contextual predictors of cyberbullying in a sample of 16, 634 students in grades 3–5 and 7–8. Data were obtained from a large cluster-randomized trial of the KiVa antibullying program that occurred in Finland between 2007 and 2009. Students completed measures at pre-intervention assessing provictim attitudes (defined as children’s beliefs that bullying is unacceptable, victims are acceptable, and defending victims is valued), perceptions of teachers’ ability to intervene in bullying, and cyberbullying behavior. Students with higher scores on provictim attitudes reported lower frequencies of cyberbullying. This relationship was true for individual provictim attitudes as well as the collective attitudes of students within classrooms. Teachers’ ability to intervene assessed at the classroom level was a unique, positive predictor of cyberbullying. Classrooms in which students collectively considered their teacher as capable of intervening to stop bullying had higher mean levels of cyberbullying frequency. Our findings suggest that cyberbullying and other indirect or covert forms of bullying may be more prevalent in classrooms where students collectively perceive their teacher’s ability to intervene in bullying as high. We found no evidence that individual or contextual effects were conditional on age or gender. Implications for research and practice are discussed.  相似文献

Body surveillance and body shame are features of objectified body consciousness that have utility in predicting body image and eating disturbances but evidence is based largely on samples in developed Western nations and it is not clear whether these factors predict disturbances independent of conceptually-related factors emphasized in alternate sociocultural accounts. To address these issues, we assessed the impact of body surveillance and body shame as well as features of other sociocultural models (i.e. perceived appearance pressure, appearance comparisons, general negative affect) on disordered eating, fatness concerns, and body dissatisfaction among young Chinese adults. University-age women (n = 466) and men (n = 230) from Chongqing, China completed validated self-report measures of demographics and the above constructs. For women, objectified body consciousness measures explained significant variance in each measure of disturbances, beyond effects of other factors; body surveillance had a unique impact in each prediction model. For men, facets of objectified body consciousness also combined for unique variance across prediction models, though body shame was the more prominent unique influence. Findings highlight the potential role of individual differences in body surveillance and body shame as influences on eating and body image of young women and men within a Chinese context.  相似文献

The paper investigates changes in IMF activities using the analytical framework of international public goods. The IMF promotes international financial stability, whose outputs are joint products with varying degrees of publicness. In recent years, IMF loans (recipient-specific benefits) have assumed decreased importance, while the Fund’s technical assistance and monitoring activities have taken on greater importance. As a consequence, the club and purely public outputs (e.g., disseminating best practices) have grown as a share of IMF activities. Changes in the mix of IMF activities alter the mix of international public goods and, in so doing, change policy recommendations regarding the role of IMF. The future of IMF is also addressed, especially in light of increased private capital flows.

Recent studies contend that negative advertising benefits voters. However, these studies only measure the volume of negativity in campaigns, often relying on survey data on voter behavior coupled with estimates of negative ad exposure. Theories of information processing indicate that the proportion of negativity may yield influences spanning a range of judgments related to candidate construction and voting behavior, yielding effects that are different from the influence of sheer volume. Thus, I argue that the proportion of negativity also has an influence, and that it is likely more often to be detrimental. I examine this claim using survey data and conclude that prevailing accounts of the effects of negative advertising campaigns are underspecified and, as a result, potentially overly optimistic.

ABSTRACT

Interracial marriage was a defining feature of interaction between local Ngāi Tahu and newcomers in southern New Zealand from the early nineteenth century. Scholarship has explored the importance of such relationships to development of New Zealand’s early resource-based economies and to colonial assimilation policies. However, the experiences of cross-cultural households and families in colonial New Zealand are less well documented.

Using a body of writing produced by fathers and their mixed-race children in response to land claims investigations in the mid-nineteenth century, this article explores the political, economic and social world of interracial families in southern New Zealand. The correspondence over land rights reveals the ongoing importance of kinship ties through generations as colonial expansion impinged on these communities. Through petitioning and letter writing, fathers and children contested what marriage and family meant and strategically asserted their individual and collective identity in the face of increasing land dispossession and economic hardship.  相似文献
