Accounts of international energy affairs often present a divergence between geopolitical/realist and liberal market-based approaches. This article suggests that this state of affairs reflects the (often implicit) legacies of realist and rationalist international thought in the study of energy affairs and the corresponding political and economic ontological hierarchies of analytical frameworks employed in different accounts of energy politics. Consequently, this article recommends a greater explicit attention to scientific ontological foundations in studies of energy relations and, in line with the calls of Keating et al. and Strange, suggests an approach based in the literature on I/GPE, which merges political and economic ontological axioms, as most apposite for the study of energy affairs. Building on this framework, and giving particular examples from the context of Eurasian energy politics, this article then outlines a number of politico-economic heuristic models (structural diversity, territorial non-coincidence, milieu-shaping and market-authority bargains) that are particularly useful concepts in helping to explain the intricate interactions of international energy relations. 相似文献

This paper discusses the controversy surrounding the Data Retention Directive with an emphasis on the 2011 decision of the Cyprus Supreme Court which has annulled several district court orders that allowed the police access to telecommunications data relating to certain persons relevant to criminal investigations. The annulment has been on the ground that the legal provisions upon which the orders have been issued are unconstitutional. It will suggest that the decision does not entail a direct rejection of the EU Data Retention Directive and that in any event, Cyprus is not a Member State resisting the particular measure. This is because the legal provisions are deemed unconstitutional, though part of the law that has transposed the relevant Directive into national law are provisions that go beyond what the EU legislator intended to regulate through that Directive. Still, the particular Directive sits rather uneasily within the ‘human rights’ regime, in particular the one governing the individual right of privacy. 相似文献

Many researchers point to gender inequities in party recruitment practices to explain women’s underrepresentation on the ballot. However, there has been little systematic research about how men and women respond to recruitment, so we do not know whether gender-balanced recruitment would actually lead to gender-balanced outcomes. We conduct two studies to address this question. First, in cooperation with a county Republican Party, we identically recruited 5510 male and 5506 female highly active party members to attend a free candidate training seminar. Republican women were half as likely to respond to the invitation as men. Second, we conducted a survey experiment of 3960 voters on the Utah Colleges Exit Poll. Republican men’s level of self-reported political ambition was increased by the prospect of elite recruitment significantly more than Republican women’s, thereby increasing the gender gap vis-à-vis the control. The gender gap in the effect of recruitment on political ambition among Democrats was much smaller. Together, these findings suggest that to fully understand the role recruitment plays in women’s underrepresentation, researchers must understand the ways in which men and women respond to recruitment, not just whether political elites engage in gendered recruitment practices. 相似文献

Previous research on the association between violence and biological stress regulation has been largely cross-sectional, and has also focused on childhood. Using longitudinal data from a low-income, high-risk, predominantly African-American sample (n = 266; 57 % female), we tested hypotheses about the influence of cumulative exposure to violence during adolescence and early adulthood on cortisol responses in early adulthood. We found that cumulative exposure to violence predicted an attenuated cortisol response. Further, we tested whether sex, mothers’ support, or fathers’ support moderated the effect of exposure to violence on cortisol responses. We found that the effect of cumulative exposure to violence on cortisol was modified by sex; specifically, males exposed to violence exhibited a more attenuated response pattern. In addition, the effect of cumulative exposure to violence on cortisol was moderated by the presence of fathers’ support during adolescence. The findings contribute to a better understanding of how cumulative exposure to violence influences biological outcomes, emphasizing the need to understand sex and parental support as moderators of risk. 相似文献

Cyberbullying is a type of bullying that involves the use of technology to harm other students. Most researchers have examined individual-level characteristics, but the perception of school climate and school characteristics such as type, size, and level of vulnerabilities have not been considered using multilevel methods. Using a sample of 8,237 Chilean seventh graders from 1,322 schools we examined individual- and school-level predictors of cyberbullying perpetration. Cyberbullying perpetration was predicted by prior victimization, interpersonal relationships, and gender. We found an interaction effect between interpersonal relationships and teacher support for victims. Our findings support the notion that school policies and culture can play a vital role in the prevention of cyberbullying, supporting a protective resilience model. 相似文献

Violence and substance use disproportionately affect African American youth in urban, disadvantaged communities. Expanding positive peer and adult connections is a mechanism by which organized activity participation may reduce risk of negative outcomes. We assessed if organized activity participation decreases the likelihood of later negative outcomes through expanding positive social connections using a parallel mediation model (Wave 1: N?=?681; 50% female; Mage?=?14.86 years; SD?=?0.65). We found indirect effects from participation to cigarette use (b?=??0.04, 95% CI: ?0.07, ?0.01) and violent behavior (b?=??0.04; 95% CI: ?0.07, ?0.01) through positive peer connections. We did not find indirect effects through positive adult connections. This may be because of the notable influence of peers on negative outcomes during adolescence. Organized activities can help youth expand positive peer connections, which, in turn, reduces risk of later negative outcomes. Implications for prevention are discussed. 相似文献

Organized activity participation provides important opportunities for adolescents to develop assets and resources related to positive youth development. Predisposing factors, in addition to sociodemographics and self-selection factors, may influence how youth participate over time. In this study, we used growth mixture modeling with longitudinal data from African American adolescents attending urban high schools in Flint, MI to identify subgroups of participation trajectories (Wave 1 N = 681, mean age at Wave 1 = 14.86 years, 51 % female). We measured activity participation using psychological and behavioral engagement across multiple contexts over the 4 years of high school. We examined how predisposing risk and promotive factors were related to these trajectories, accounting for sociodemographic and self-selection factors. The results indicated three participation trajectories: a low group decreasing over time (74 %), a moderate, consistent participation group (21 %) and a moderate, increasing group (5 %). More substance use was associated with lower odds of being in the moderate/consistent versus low/decreasing participation group. More parental support was associated with lower odds of being in the moderate/increasing versus the moderate/consistent group. Our results suggest that addressing predisposing factors such as substance use may help facilitate participation over time. 相似文献

In the quest for a simple, reliable technique to estimate the sex of human remains several novel metric skeletal indices have been reported. Only a few have been examined for utility in populations different from those in which they were developed. In this study, the mastoid process was evaluated for sex determination using 102 lateral cephalograms of a Nigerian sample of known age and sex. The asterion‐mastoidale distance and mastoid triangular area were sexually dimorphic with mean values higher in males compared with females (p = 0.02). On analysis of the discriminant function, overall accuracy for sex classification was 55%. On cross‐validation, the triangular area accurately identified 80% of females and 48% of males. The asterion‐mastoidale distance was slightly more accurate at sexing the sample. The practical utility of the mastoid triangle area technique to differentiate sex in Nigerian populations is not supported by the results of this study. 相似文献
