Abstract

This article analyses party strategies during the campaign for the Dutch general election of March 2017, making use of issue-yield theory. It investigates whether parties strategically emphasise high-yield issues, by juxtaposing the issue opportunities provided by voters with parties’ issue emphasis during the campaign. More specifically, it asks whether parties strategically emphasised issues that were expected to reward them electorally. Analysing voter preferences and party campaign data, it is found that parties and most of their constituencies show high ideological consistency, that parties emphasise mostly positional issues and thus choose a conflict-mobilising strategy, and that most parties emphasise high-yield issues rather than following the general political agenda. Four small parties that won significantly behaved strategically while the social democrats – who severely lost – hardly did. The findings imply that the issue-yield framework can help to explain the election result in the fragmented Dutch multi-party context.  相似文献

Abstract

Recent debates in international relations seek to decolonize the discipline by focusing on relationality between self and other. This article examines the possibilities for preserving a particular type of otherness: ‘radical otherness’ or ‘alterity’. Such otherness can provide a bulwark against domination and colonialism: there is always something truly other which cannot be assimilated. However, two problems arise. First, if otherness is truly inaccessible, how can self relate to it? Does otherness undermine relationality? Second, can we talk about otherness without making it the same? Is the very naming of otherness a new form of domination? This article draws out and explores the possibilities for radical otherness in sinophone and anglophone relational theorizing. It addresses the difficulties presented by the need for a sense of radical otherness, on the one hand, and the seeming impossibility of either detecting it or relating to it, on the other. By constructing a typology of four accounts of otherness, it finds that the identification and preservation of radical otherness poses significant problems for relationality. Radical otherness makes relationality between self and other impossible, but without radical otherness there is a danger of domination and assimilation. This is common to both sinophone and anglophone endeavours.  相似文献

Abstract

What is ‘relational theorizing’ in International Relations and what can it offer? This article introduces a thematic section that responds to these questions by showing two things. First, relational theorizing is not a doctrine or a method, but a set of analyses that begin with relations rather than the putative essences of constitutively autonomous actors. Second, relational theorizing has emerged from different geo-linguistic traditions, and a relational approach to International Relations (IR) can offer the language and space for increased and productive engagement beyond Anglophone scholarship. This thematic section takes a significant step in this direction by staging a dialogue between Sinophone and Anglophone scholarship on relational IR theorizing. Such an engagement shows points of comparison and contrast, convergence and divergence. In this way, the essays presented here contribute to developing a more ‘global’ IR.  相似文献

This article explores the potential of using children’s perceptions of distance to reflect a gendered understanding of remoteness. Data collected from 1,549 children in Tanzania concerning their perceptions of remoteness in relation to accessibility of school, health care, and water resources were analysed in reference to their impact on school attendance and performance. Gendered variability in perceived distances to services by children may indicate that remoteness is as much of a social issue as it is a geographic phenomenon, in that girls perceive distance and time between home and destination to be further than boys who travel approximately the same distance.  相似文献

Young adulthood represents a developmental period with disproportionately heightened risk of losing a job. Young adult unemployment has been linked to increased mental health problems, at least in the short term. However, their possible long-term impacts, often referred as “scarring effects,” have been understudied, possibly underestimating the magnitude of mental health burden that young adult unemployment generates. This longitudinal study examined whether duration of unemployment during young adulthood is associated with later mental health disorders, after accounting for mental and behavioral health problems in childhood. Furthermore, the current study investigated whether childhood neighborhood characteristics affect this association and if so, in what specific functional ways. Data were drawn from a longitudinal study of developmental outcomes in a community sample in Seattle. Data collection began in 1985 when study participants were elementary students and involved yearly assessments in childhood and adolescence (ages 10–16) and then biennial or triennial assessments (ages 18–39; N?=?677 at age 39; 47% European American, 26% African American, 22% Asian American, and 5% Native American; 49% female). The current study findings suggest that duration of unemployment across young adulthood increased mental health problems at age 39, regardless of gender. Childhood neighborhood characteristics, particularly their positive aspect, exerted independent impacts on adult mental health problems beyond unemployment experiences across young adulthood. The current findings indicate a needed shift in service profiles for unemployed young adults—a comprehensive approach that not only facilitates reemployment but also addresses mental health needs to help them to cope with job loss. Further, the present study findings suggest that childhood neighborhoods, particularly positive features such as positive neighborhood involvement, may represent concrete and malleable prevention targets that can curb mental health problems early in life.

There is strong evidence that chronic, systemic inflammation hastens onset of the diseases of old age that ultimately lead to death. Importantly, several studies suggest that childhood adversity predicts chronic inflammation. Unfortunately, this research has been plagued by retrospective reports of childhood adversity, an absence of controls for adult stressors, and a failure to investigate various competing models of the link between childhood adversity and chronic inflammation. The present study was designed to address these limitations. Using 18 years of data collected from 413 African Americans (58% female) included in the Family and Community Health Study, hierarchical regression analyses provided support for a nuanced early life sensitivity explanation for the link between early adversity and adult chronic inflammation. Controlling for health risk behaviors and adult SES, late childhood (ages 10–12) adversity amplified the association between adult adversity (age 29) and chronic inflammation. This interaction operated in a domain-specific fashion. Harsh parenting amplified the relation between intimate partner hostility and inflammation, whereas early discrimination amplified the relation between adult discrimination and inflammation. These findings suggest that individuals may be primed to respond physiologically to adverse adult circumstances that resemble those experienced earlier in life.
