International organizations (I0) have centralized their public communication to a large extent over recent decades by undertaking a broader codification of communication tasks as well as a departmentalization of these tasks within units of IO bureaucracies. The paper provides the first systematic analysis of this important development in institutional design using a novel data set on the organization of public communication in 48 IOs between 1950 and 2015. It identifies self-legitimation as a key driver of centralization in the face of increased levels of politicization, that is, public awareness and activism directed at IOs. Empirically, the study suggests that the centralization of public communication significantly increases as transnational civil society organizes and gains access to IO decision-making. Further, politicization in terms of contentious activism and public scandals substantially accounts for varying levels of centralization across IOs.  相似文献

One main source of sexual socialization lies within family interactions. Especially sexuality-specific parenting may determine adolescents’ sexual development—adolescents’ sexual behavior and sexual risk behavior, sexualized media consumption and permissive sexual attitudes—to a significant extent, but different ideas exist about how this works. In this longitudinal study, we examined two hypotheses on how sexuality-specific parenting—parenting aimed specifically at children’s sexual attitudes and behaviors—relates to adolescents’ sexual development. A first buffer hypothesis states that parents’ instructive media discussions with their children—called instructive mediation—buffers the effect of sexualized media consumption on adolescents’ sexual attitudes and behavior and, vice versa, the effect of adolescents’ sexual attitudes and behavior on sexualized media consumption. A second brake hypothesis states that parents, by communicating love-and-respect oriented sexual norms, slow down adolescents’ development toward increased sexualized media use, permissive sexual attitudes, and sexual behavior and sexual risk behavior. Using four-wave longitudinal data from 514 Dutch adolescents aged 13–16 years (49.8% female), we found evidence to support a brake effect. More frequent parental communication of love-and-respect oriented sexual norms was associated with less permissive sexual attitudes and, for boys, with less advanced sexual behavior and a less rapid increase in sexual risk behavior. Parents’ instructive mediation regarding adolescents’ sexualized media consumption was associated with less permissive sexual attitudes at baseline, but only for girls. No systematic evidence emerged for a buffer effect of parents’ instructive mediation. In conclusion, although our data seem to suggest that parent–child communication about sex is oftentimes “after the fact”, we also find that more directive parental communication that conveys love-and-respect oriented sexual norms brake adolescents’ move toward sexual maturity.  相似文献

Although peer victimization is of major concern and adolescents spend increasing amounts of time on the Internet, relatively little is known about the psychosocial antecedents and consequences of online victimization. The main aim of this study was to compare the psychosocial antecedents and consequences of online versus real-life victimization. More specifically, the bidirectional relationship between online and real-life victimization on the one hand and psychosocial problems (i.e., loneliness and social anxiety) on the other was examined. In addition, the moderating role of online aggression in the relationship between online victimization and subsequent psychosocial problems was studied. This prospective study, consisting of three annual measurements, was conducted among a sample of 831 adolescents (50.3 % girls) aged 11–15, of which most (80.2 %) had a Dutch ethnic background. The results indicate a unidirectional relationship whereby loneliness and social anxiety predict an increase in latter online victimization rather than the reverse. A bidirectional relationship was found for real-life victimization: loneliness (but not social anxiety) predicted an increase in latter real-life victimization, which in turn predicted an increase in subsequent social anxiety (but not loneliness). No moderating effects of online aggression were found. The findings of the present study suggest that negative online and in real life peer interactions have a differential meaning for, and impact on adolescents’ well-being.  相似文献

International development cooperation is undergoing fundamental changes. New – or often re-emerging – actors have gained importance during the past two decades, and are increasingly challenging the traditional approach to development cooperation associated with the members of the Development Assistance Committee of the oecd. Their supposedly alternative paradigm, ‘South–South cooperation’ (ssc), has been recognised as an important cooperation modality, but faces contradictions that are not too different from those of its North–South counterpart. ssc providers are highly heterogeneous in terms of policies, institutional arrangements, and engagement with international forums and initiatives. This article contributes to current debates on ssc by mapping the diversity of its actors – based on illustrative case studies from the first and second ‘wave’ of providers – and by presenting and discussing some possible scenarios for the future of ssc within the international aid system.  相似文献

School districts are faced with the challenge of how best to serve the needs of a growing homeless student population. As the numbers of homeless children and youth continue to rise, it is imperative for educators and others to understand the experiences of unaccompanied homeless youth. A qualitative research project was undertaken to obtain the perspectives of six high school students experiencing homelessness. These perspectives illuminate the various and multiple factors intersecting with student's educational lives. Their narratives uncovered the following themes: (a) Homelessness as a misnomer, (b) Homelessness is not a choice, (c) Caring adults, and (d) Student agency. Their counternarratives challenge adults working with unaccompanied homeless youth to rethink and reimagine the manner in which homelessness is understood and framed; this is especially critical in educational spaces. Schools often are the primary contexts in which youth spend their time and can be instrumental to providing youth experiencing homelessness with the support and resources they identify as being critical to their educational engagement and success.  相似文献

Voters normally split their tickets when they do not feel sufficiently represented by only one political party or when politicians cultivate a personal vote regardless of party identification. Yet, voters might also split their tickets when they feel indifferent about like-minded parties or individual candidates. The authors distinguish between misalignment ticket-splitting (MATS), caused by a mismatch between voters’ preferences and the alternatives offered by the party system, and mis-coordination ticket-splitting (MCTS), when like-minded parties offer choices equally acceptable to voters. MCTS is likely to occur under proportional representation systems with multiple parties. The authors apply our categorization to concurrent presidential and legislative elections in Chile in 2005 and 2009. There was plenty of MCTS but little MATS. The authors suggest that the two forms should be separately analyzed as they are reflective of different political phenomena.  相似文献

Financial and political factors are widely considered to be an explanatory factor of the privatisation of public services. However, the empirical evidence in this respect is not convincing. This paper considers elements of long-term financial condition and ideological and political strength, together with other socio-economic factors and the effects of the current global financial crisis, to address the financial stress–privatisation relationship, with respect to urban water services, observed during the period 2002–2012 in Spanish municipalities. A discrete time survival model is applied, and the results obtained show that certain elements of financial condition, together with political and ideological factors, are decisive influences in decisions to privatise urban water services. We also highlight the major impact of the Great Recession and its effect on the financial stress–privatisation relationship.  相似文献

This article analyzes the testimonial literature of Latin American exile within the wider framework of studies of exile and post-exile. It claims that testimonies have an important role in providing access to the multiple and reflexive voices of exiles and expatriates, which are relevant to the reconstruction of the recent history of Latin America. Their relevance lies in enabling analysis to move beyond the heroic, Byronic vision of exile towards a less idealistic yet more intimate understanding of the gains and losses of territorial displacement, as well as the tensions, ambiguities, and conflicts developing within the communities of exiles, as they face new challenges. Exile testimonies also allow research to trace the development of a broader sense of identity extending beyond territorial borders and expressed in the awareness of being part of national Diasporas and, for many, also a Latin American transnational consciousness.  相似文献

Previous correlational research indicates that adolescent girls who use social network sites more frequently are more dissatisfied with their bodies. However, we know little about the causal direction of this relationship, the mechanisms underlying this relationship, and whether this relationship also occurs among boys to the same extent. The present two-wave panel study (18 month time lag) among 604 Dutch adolescents (aged 11–18; 50.7 % female; 97.7 % native Dutch) aimed to fill these gaps in knowledge. Structural equation modeling showed that social network site use predicted increased body dissatisfaction and increased peer influence on body image in the form of receiving peer appearance-related feedback. Peer appearance-related feedback did not predict body dissatisfaction and thus did not mediate the effect of social network site use on body dissatisfaction. Gender did not moderate the findings. Hence, social network sites can play an adverse role in the body image of both adolescent boys and girls.  相似文献
