The present investigation examines mediated pathways from pubertal development to changes in depressive affect and aggression. Participants were 100 white girls who were between the ages of 10 and 14 (M=12.13, SD=.80); girls were from well-educated, middle- to upper-middle class families, and attended private schools in a major northeastern urban area. Three aspects of pubertal development were examined: (a) estradiol categories tapping gonadal maturation; (b) dehydroepiandrosterone sulfate (DHEAS) levels indicating adrenal maturation; and (c) pubertal timing (early vs. other). Three potential mediators were also examined: emotional arousal, attention difficulties, and negative life events. Tests of mediated models indicated that early pubertal timing predicted higher emotional arousal which subsequently predicted increased depressive affect. Negative life events, and possibly attention difficulties, mediated the associations of both estradiol category and DHEAS with aggression. These findings highlight the potential for more intensive investigation of gonadal and adrenal processes in explaining affective changes at puberty.

In the wake of the “audit revolution” during the 1980s and 1990s, administrative systems across the western world have tended to gradually downplay evaluation as a component of the policy process. At the same time, auditing has dramatically increased in scope and depth, and has also, to some extent, come to fill the role in policymaking previously played by evaluation studies. This article reviews this development from the perspective of policymaking and institutional change or “drift.” Specifically, we look at the types of information and knowledge that are lost and gained as a result of these developments. We apply a cross‐national approach, drawing on the examples from the European and North American contexts.  相似文献

While global plurilateral summit institutions (PSIs) of the world's most powerful countries have long generated effective global health governance, the most recent summits of the Group of Eight (G8) and the Group of 20 (G20) have largely abandoned their earlier concern with health, especially outside its specialized food and nutrition link. However, since its start in 2009 in Yekaterinburg, Russia, the annual summit of Brazil, Russia, India, China and now South Africa (BRICS), a new PSI arising has substantially addressed health and started to lead in some ways. The BRICS summit-level health governance has been reinforced by the advent of a BRICS health ministers' forum, other health-related ministerial institutions (notably for agriculture and trade) and official and multi-stakeholder bodies. This article provides the first direct, disciplined empirical analysis of how and why the BRICS summit system has governed global health, based on the models developed for and applied to G8, G20 and United Nations summit governance.  相似文献

Youth in early adolescence are highly concerned with being popular in the peer group, but the desire to be popular can have maladaptive consequences for individuals. In fact, qualitative work suggests that youth with high popularity goals who are nonetheless unpopular have negative experiences with their peers. However, little quantitative work has examined this possibility. The purpose of the current study was to examine if popularity goals were linked with physical (e.g., being hit) and relational (e.g., being excluded) victimization and peer rejection, particularly for individuals who strived for popularity but were viewed by their peers as unpopular. Late elementary and early middle school participants (N?=?205; 54% female) completed self-reports of popularity goals and peer nominations of popularity and peer rejection. Teachers reported on students’ experiences of relational and physical victimization. Peer nominated popularity and gender were moderators of the association between popularity goals and negative peer experiences. Consistent with hypotheses, girls who were unpopular but wanted to be popular were more likely to experience peer rejection and relational victimization. Unexpectedly, boys who were unpopular but did not desire to be popular were more likely to be rejected and relationally victimized. The findings suggest that intervention and prevention programs may benefit from addressing the social status goals of low status youth in a gender-specific manner.  相似文献

ABSTRACT

Constructing convincing legitimacy claims is important for securing the stability of authoritarian regimes. However, extant research has struggled to systematically analyse how authoritarians substantiate their right to rule. We analyse a novel data set on authoritarian regimes’ claims to legitimacy that is based on leading country experts’ assessments of 98 states for the period 1991–2010. This analysis provides key new insights into the inner workings and legitimation strategies of current non-democratic regimes. Closed authoritarian regimes predominately rely on identity-based legitimacy claims (foundational myth, ideology and personalism). In contrast, elections fundamentally change how authoritarian rulers relate to society. In their legitimacy claims, electoral authoritarian regimes focus on their ‘adequate’ procedures, thereby mimicking democracies. All regimes also stress their purported success in proving material welfare and security to their citizens.  相似文献

ABSTRACT

The study of legitimacy in situations of conflict and peacebuilding has increased in recent years. However, current work on the topic adopts many assumptions, definitions, and understandings from classical legitimacy theory, which centers on the relationship between the nation-state and its citizens. In this introduction, we provide a detailed critical overview of current theories of legitimacy and legitimation and demonstrate why they have only limited applicability in conflict and post-conflict contexts, focusing on the three main areas that the articles included in this special issue examine: audiences for legitimacy, sources of legitimacy, and legitimation. In particular, we show how conflict and post-conflict contexts are marked by the fragmentation and personalization of power; the proliferation and fragmentation of legitimacy audiences; and ambiguity surrounding legitimation strategies.  相似文献
