The principle of absolute sovereignty may have been consigned to history, but a strong presumption against foreign intervention seems to have been left in its stead. On the dominant view, only massacre and ethnic cleansing justify armed intervention, these harms must be already occurring or imminent, and the prudential constraints on war must be satisfied. Each of these conditions has recently come under pressure. Those looking to defend the dominant view have typically done so by invoking international peace and stability, or the value of communal self-determination. But the internal aspect of legitimacy has been overlooked in all of this. If a government insists on defending the human rights of foreigners, it must also be sure not to violate the rights of its own citizens in the process. I argue that the current presumption against humanitarian intervention cannot be substantially relaxed for internal reasons, or given the obligations that states owe to their own constituents.  相似文献

The results of this study provide insights into the ways that African American adolescents think about gendered interpersonal violence. African American high school students were invited to discuss images and incidents from contemporary urban music culture (events based on incidents with famous hip hop figures and lyrics from rap music) in a focus group format. We explored how African American youth perceived and responded to examples of gendered violence portrayed in vignettes and musical lyrics. The main analyses focus on the question of how youths’ perceptions of hip hop images, hypothetical stories, and lyrics were linked to their views of “normative” gender interactions and interpersonal relationships for their racial group.  相似文献

In light of the continual problem of attrition in the field of special education and the need for well-prepared new special education teachers, the purpose of this study was to examine how dialogic reflective e-journaling between the first author and undergraduate preservice teachers impacted the classroom decision-making as well as the transformative learning of these preservice teachers involved in a special education field-based experience in US schools. Performance feedback was given by the first author as part of the teacher preparation supports already in place for the field-based experience. Study findings revealed that dialogic e-journaling enhanced the reflective skills of the study participants when faced with classroom disorienting dilemmas and instigated a positive personal transformation in them as teachers.  相似文献

Little systematic information exists about how community‐based prevention efforts at the state and local levels contribute to our knowledge of intimate partner violence (IPV) prevention. The Centers for Disease Control and Prevention's (CDC) DELTA FOCUS program funds ten state domestic violence coalitions to engage in IPV primary prevention through approaches addressing the outer layers of the social ecology. This paper explored the ways in which DELTA FOCUS recipients have contributed to a national‐level dialogue on IPV prevention. Previously undefined, the authors define national‐level dialogue and retrospectively apply the CDC Science Impact Framework (SIF) to describe contributions DELTA FOCUS recipients made to it. Authors conducted document review and qualitative content analysis of recipient semi‐annual progress reports from 2014 to 2016 (= 40) using NVivo. A semi‐structured coding scheme was applied across the five SIF domains: Creating Awareness, Catalyzing Action, Effecting Change, Disseminating Science, and Shaping the Future. All recipients sought to promote IPV prevention by communicating and sharing with non‐CDC‐funded state coalitions, national partners, and other IPV stakeholders information and resources accumulated through practice‐based prevention efforts. Through implementing and disseminating their prevention work in myriad ways, DELTA FOCUS recipients are building practice‐based evidence on community‐based IPV prevention.  相似文献

This study examined the structure and symptom specific patterns of post traumatic distress in a sample of 1,581 adolescents who reported exposure to at least one traumatic event. Symptom reporting patterns are consistent with past literature in that females reported more symptoms than males and older youth reported more symptoms than did their younger peers. Young people reporting exposure to exclusively violent type traumas were also found to be more likely to endorse symptoms than peers exposed exclusively to non violent type traumas. Confirmatory factor analysis provided stronger support for a four-factor model of PTSD than either the DSM-IV model or an alternate model. Further examination of the four factor model revealed gender differences in factor loadings with small to moderate effect sizes for recurrent, distressing memories, flashbacks, restricted affect, difficulty remember details, detachment, limited future orientation, hypervigilance and startle symptoms. Differences in factor loadings with the four factor model were also noted between younger and older adolescents, with medium to large effect sizes on the arousal items. In contract, comparison of the factor loadings revealed only small differences between youth exposed exclusively to violent traumatic stressors and those exposed exclusively to non violent traumatic stressors, suggesting relative similarity between these two groups.  相似文献

Social network analysis: A methodological introduction   总被引:3,自引:0,他引:3  
Social network analysis is a large and growing body of research on the measurement and analysis of relational structure. Here, we review the fundamental concepts of network analysis, as well as a range of methods currently used in the field. Issues pertaining to data collection, analysis of single networks, network comparison, and analysis of individual-level covariates are discussed, and a number of suggestions are made for avoiding common pitfalls in the application of network methods to substantive questions.  相似文献

Low birth rates and population ageing have slowed population growth rates in Canada, and immigration has become the primary driver of population and labour force growth in the nation. The distribution of new arrivals to Canada, however, has been concentrated in a few major cities. Until recently, Montreal, Toronto and Vancouver have been the destination of approximately 75% of all immigrants. All orders of government have introduced policies and programs to influence the regional distribution of immigrants across the country, ostensibly so that the benefits of immigration will be more evenly shared on a national basis. An assessment of the Manitoba Provincial Nominee Program helps identify policy and program initiatives and best practices effective in changing the regional distribution of immigrants and attracting more new arrivals to smaller urban and rural communities.  相似文献

An experimental comparison of two commonly used delay-discounting procedures (binary choice and fill in the blank) and modes of administration (paper and pencil and computer based) was conducted. Statistically significant main effects were found for task type—steeper discounting was observed in the binary-choice task— but not for mode of administration. As simple evidence of validity, hyperbolic curves consistently provided a better fit to the data than did exponential curves for both tasks. Further, magnitude effects were also observed across conditions. Correlational results varied largely as a function of the discounting index (either k or area under the curve) under consideration. Across the two tasks, discounting indices showed modest levels of reliability [r(AUC)=.33; r(k)=.75]. The findings pointed to refinements for both the methodology and criteria that are used to study delay discounting and raised questions about the commonly assumed relationship between discounting and the construct of impulsivity.  相似文献
