As regions become more institutionalized, they are characterized by two competing trends. First, key regional institutions can become hub institutions that act as transmitters of a comprehensive set of norms. Second, as regional institutions increase in number, regions themselves are liable to become more fragmented. How these trends have played out is explored in two key regions, the Americas and the Asia-Pacific. It is concluded that regions are not static entities but are ever-changing structural arrangements. Hub institutions can be challenged and the consequences can be significant as regions gain in importance on the international stage.  相似文献

Tolerance is treated as a virtue and a key principle in liberal theories of the state and human rights. Critics of liberalism have already addressed limitations of tolerance, and the United Nations (UN) introduced broader and more inclusive human rights and non-discrimination norms. Yet, tolerance is still invoked in human rights advocacy, and the UN promotes teaching tolerance as a means to protect human rights. However, there is an asymmetrical relationship between the “tolerant” and the “tolerated,” which must be questioned for its human rights implications. The paper contends that tolerance does not ensure non-discrimination, freedom from persecution, or ending violence. Instead, it can be complicit in violence against lesbian, gay, bisexual, and transgender (LGBT) persons. As an illustrative case, it examines Turkey—a country that has pursued the liberal policy of tolerance by not criminalizing homosexuality—during a reform period that involved further liberalization of law but not the protection of LGBT rights.  相似文献

Getting along with peers becomes increasingly important to health and well-being during early adolescence (10–14 years). Young adolescents may succeed with peers when they are well-liked by and popular among the larger peer group (or at the group-level of social complexity). They might also fare well with peers when they are able to form numerous mutual and high quality friendships (at the dyadic-level of social complexity). Theory emphasizes the interrelatedness of different types of peer experiences, but few longitudinal studies have examined the interplay among and between group- and dyadic-level peer experiences in the same study. As a result, it is not known whether group-level peer experiences are predictors of dyadic-level peer experiences, and/or vice versa. To address this limitation, this study examined the prospective and reciprocal relations between four indices of peer experiences, preference (or being highly liked and not disliked by peers), popularity (or having a reputation as popular), friendship quantity (or having many mutual friends), and friendship or relationship quality, during early adolescence. Participants were 271 adolescents (49% girls; Mage?=?11.52 years) who completed peer nominations of preference and popularity, a self-report measure of friendship quality, and nominated friends at two waves (Wave 1: November, Grade 6; Wave 2: October, Grade 7). Structural equation modeling indicated that friendship quantity predicted increases in preference and popularity and that friendship quality predicted increases in friendship quantity. Initial popularity was associated with decreases in preference. The importance of these findings for future research is discussed along with study limitations.  相似文献

There is broad agreement that neighborhood contexts are important for adolescent development, but there is less consensus about their association with adolescent smoking and alcohol use. Few studies have examined associations between neighborhood socioeconomic contexts and smoking and alcohol use while also accounting for differences in family and peer risk factors for substance use. Data drawn from the Seattle Social Development Project (N?=?808), a gender-balanced (female?=?49%), multiethnic, theory-driven longitudinal study originating in Seattle, WA, were used to estimate trajectories of smoking and alcohol use from 5th to 9th grade. Time-varying measures of neighborhood socioeconomic, family, and peer factors were associated with smoking and alcohol use at each wave after accounting for average growth in smoking and alcohol use over time and demographic differences. Results indicated that living in more socioeconomically disadvantaged neighborhoods, lower family income, lower family general functioning, more permissive family smoking environments, and affiliation with deviant peers were independently associated with increased smoking. Lower family functioning, more permissive family alcohol use environments, and deviant peers were independently associated with increased alcohol use. The effect of neighborhood disadvantage on smoking was mediated by family income and deviant peers while the effect of neighborhood disadvantage on alcohol use was mediated by deviant peers alone. Family functioning and family substance use did not mediate associations between neighborhood disadvantage and smoking or alcohol use. The results highlight the importance of neighborhood, family, and peer factors in early adolescent smoking and alcohol use. Future studies should examine the unique association of neighborhood disadvantage with adolescent smoking net of family socioeconomics, functioning, and substance use, as well as peer affiliations. Better understanding of the role of contextual factors in early adolescent smoking and alcohol use can help bolster efforts to prevent both short and long harms from substance use.  相似文献

In recent years regional representation offices have proliferated in Brussels. Among the many aims of these offices are influencing the allocation and securing the transfer of European Structural and Cohesion funds. However, our knowledge about whether they have succeeded in this goal is limited. In this paper, we assess whether regional offices in Brussels have managed to affect the commitment and payment of Structural and Cohesion funds beyond the officially stated economic criteria of eligibility. The paper uses a custom-made survey of Brussels offices, complemented by economic, institutional, and political data. The results of the analyses for 123 regions over the period 2009–13 highlight that the capacity – proxied by the budget and staff of the office – of the regional offices to influence the commitment and payment of Structural and Cohesion funds has been negligible, when not outright negative. Regional lobbying in Brussels does not lead to more funds or to an easier disbursement of regional development funds.  相似文献

Research on the use of municipal corporations to deliver local and regional public services has evolved significantly in the past decade. Most of this work addresses the performance of this service-delivery mode in relation to local bureaucracies. However, much less is known about the drivers for the adoption of municipal corporations in the first place. This article reviews the main determinants of adoption – service characteristics, institutional and regulatory settings, political constraints and financial conditions – and highlights the need for comparative research across countries.  相似文献

This paper explores the relationship between ground rent, production and knowledge in Ecuador’s neo-structuralist, state-led project to transform the productive matrix. Based upon insights from the Marxian approach to the critique of political economy, we interrogate how neo-structuralism has conceptualised the relationship between ‘natural resource income’ and ‘knowledge-based’ economic development. The paper argues that a rent-theoretical perspective, which takes seriously the regional unfolding of uneven geographical development in Latin America, can highlight the limits of a national development plan conceived according to the logic of Schumpeterian efficiency. In doing so, the paper identifies the contradictory relationship between natural resource exports, state-led ‘knowledge’-based development and capital accumulation. On this basis the paper offers a historically and empirically informed critical analysis of selective import substitution industrialisation and vanguard science and technology strategies designed to transition Ecuador away from primary resource dependence.  相似文献

This essay examines the competing readings of food refusal that emerged from a student hunger strike held at Columbia University in fall 2007. The invisibility of the act of food refusal forces hunger strikers to adopt performance strategies that make their (non)action visible as protest. To make the politics of their food refusal legible, advocates for the hunger strike promoted their actions as part of a 40 year tradition of student protest. However, that same invisibility allowed the protest's detractors to deride the hunger strikers as anorexic. At the center of the protest and the commentary about it was a wasting female body that confused for spectators the line between the political and the pathological. Attention to this body raises questions of how community is created and disciplined through performative acts, how easily female protest is evacuated of political meaning and the uneasy role of whiteness in popular attention to anorexia.  相似文献

Abstract

We used survey and ethnographic data to study savings in a highly autarkic society of native Amazonians in Bolivia (Tsimane’). We equated savings with the amount of maize and rice in storage, area planted with plantains and manioc, and number of edible domesticated animals owned by a household or an adult. We found no large inter-annual change in savings possibly due to low income, impulsivity and a bundle of institutions and norms, such as borrowing, theft and reciprocity norms. The bundle attenuates the need for household formal savings at the periphery of markets.  相似文献

Peer victimization is a common problem among adolescents that has been linked to a variety of adjustment problems. Youth involved in peer victimization represent a heterogeneous group who may differ not only in their levels of victimization and perpetration, but also in the factors that influence their behavior. The current study used latent class analysis (LCA) to identify subgroups of aggressive and victimized youth, and to examine social-cognitive and environmental factors that differ across these subgroups. Participants were a predominantly African-American (i.e., 68 %) sample of 502 sixth, seventh, and eighth graders (45 % male, Mean age = 12.6 years) attending three urban public middle schools, who completed self-report measures of aggression, victimization, and associated individual and contextual factors. LCA identified four classes of adolescents representing non-victimized aggressors, aggressive-victims, predominantly victimized youth, and well-adjusted youth. Class differences were found on measures of beliefs supporting fighting, beliefs against fighting, perceived effectiveness of inept nonviolent responses to conflict, behavioral intentions to engage in aggressive and nonviolent behavior, self-efficacy for nonviolent behavior, and peer and parental support for aggression and nonviolence. For example, within the two classes of victimized youth, aggressive-victims reported greater intentions to engage in physical aggression and inept nonviolent behavior, and were more likely to agree with beliefs supporting the use of instrumental and reactive aggression, and beliefs that fighting is sometimes necessary compared to predominantly victimized youth. These findings emphasize the importance of developing preventive interventions that target the specific needs of distinct subgroups of adolescents.  相似文献
