Marginal regions have been the subject of political concern and remedial action in western states for several decades now. The West Coast of the South Island of New Zealand is an interesting case study in this regard, for recent economic growth has confounded earlier expectations of post-restructuring decline, while also contradicting several of the nostrums of new regionalism. In an effort to understand this trajectory, this paper draws on documents from public and private sector organisations, newspaper articles and field visits to examine developments in four key sectors of the West Coast's economy: mining, dairy farming, forestry and tourism. Economic growth is found to be closely linked to the cultivation of new markets for primary products, but efforts to rework the cultural dimensions of marginality have also been important. Value has been added to specific products through the insertion of references to the region's alpine and forested landscapes. Isolation and peripherality have been recast in more positive terms, echoing the broader reframing of New Zealand as a scenic, unspoiled destination. In adopting a cultural economic perspective on marginal regions, the paper illustrates the significance of symbolic forms of value, the potentially flexible nature of marginality as a discursive category, and the importance of the networks which connect regions to national and international flows of capital and tourists.  相似文献

It is common to understand the governing of rural space as the outcome of a conflict between some romantic protectors of a lost past on the one hand, and the people who worry about creating economic values on the other. However, the power to shape the rural should not only be searched for in the open struggle between protectors and developers, but also should be analysed at the level of discourse, in the play between discourses about how to deal with the rural. In this paper I therefore present a modernist discourse and demonstrate how taken-for-granted truths about the rural – its history, its present and its future – are made possible by this discourse. Secondly, I will reveal how rurality takes on a different meaning in an alternative to the modernist discourse, emphasizing local and regional autonomy. In demonstrating that rurality is contingent upon a play between these two discourses, I want to provide some new insights into an important force behind the persistence of ideas about rurality in Norway.  相似文献

Anxiety disorders are among the most common psychiatric disorders in children and adolescents. Most empirically supported treatments (ESTs) for pediatric anxiety disorders include various cognitive-behavioral methods. Although demonstrated efficacious in controlled and clinic settings, there are barriers to implementing these types of therapies in social work settings due to beliefs about the usefulness of ESTs in community settings; limitations of treatment manuals; time constraints of implementing ESTs; fidelity and flexibility of implementing ESTs; and limited training opportunities. This article provides an overview of ESTs for childhood anxiety disorders, highlighting options for overcoming common barriers to implementing ESTs. Collaborative multi-method approaches to advance implementation of ESTs in social work practice are suggested.  相似文献

Public administration scholars often associate increased publicparticipation in policy implementation with the advancementof democratic values. Likewise, scholars engaged in the variousforms of action research (AR) promote their efforts as a meansto democratizing the research process or contributing to improvedsocial outcomes. Despite these common interests in participationand democracy, there have been few attempts to apply AR methodsto policy implementation problems. Drawing on Matland's conflict-ambiguitymatrix, we develop a framework for matching particular AR methodsto specific policy implementation contexts.  相似文献

This paper presents barriers to help-seeking data as reported by users of a national gambling helpline (help-seekers, HS, N = 125) as well as data pertaining to perceived barriers to seeking help as reported by gamblers recruited from the general population (non-help-seekers, NHS, N = 104). All data were collected via a structured, multi-modal survey. When asked to identify actual or perceived barriers to seeking help, responses indicative of pride (78% of HS participants, 84% of NHS participants), shame (73% of HS participants, 84% of NHS participants) or denial (87% of NHS participants) were most frequently reported. These three factors were also most often identified as the real or perceived primary barrier to help-seeking (collectively accounting for 55% of HS, and 60% of NHS, responses to this question) and were the only barriers to be identified by more than 10% of either HS and NHS participants without prompting. It was of note, however, that participants in both groups identified multiple barriers to help-seeking (mean of 6.7 and 12.2, respectively) and that, when presented with a list of 21 possible barrier items, NHS participants endorsed 19 of the listed items significantly more often than their HS counterparts. The implications of these findings, with respect to promoting greater or earlier help-seeking activity amongst problem gamblers, are discussed.

The present paper develops and tests two temporal models of the relationships among adolescents' ethnic identity exploration, ethnic identity affirmation and belonging, and attitudes toward their racial/ethnic ingroup and outgroups. Structural equation models for Euro‐Americans, Asian Americans, and Latinos revealed that all hypothesized relationships were positive and significant. The model in which ethnic identity exploration (at Time 1) predicts ethnic identity affirmation and belonging (at Time 2) was superior to the alternative model in which the relationship between them was reversed (i.e., affirmation and belonging at Time 1 predicts exploration at Time 2). Results (1) support the importance of exploration as a basis for establishing a secure attachment to one's ethnic identity, which, in turn, has positive implications for attitudes toward one's own group and other groups and (2) suggest that maintenance of ethnic identity is compatible with positive attitudes toward ethnic outgroups.  相似文献

Urban biodiversity conservation needs a firm scientific foundation, one that draws upon active and regionally calibrated research programs. Until recently this foundation has not existed. In this paper we examine the way in which the emerging discipline of restoration ecology in an urban context can learn from the experiences of ongoing restoration projects and in turn how novel insights from research of urban soils can help these projects define and reach their goals. Limitations on collaboration between academic researchers and practitioners continues be problematic. We discuss a model whereby this impediment may be removed. A case study of Rhamnus cathartica, an invader of Midwestern woodlands which modifies some important soil ecosystem properties will be used to illustrate the potential for engagement between research and practice.  相似文献

We identify the political conditions that shape the economicposition of married/cohabiting women and of the economicallymost vulnerable group of women—single mothers. Specifically,we examine the determinants of reductions in single mothers'poverty rate due to taxes and transfers, and women's wages relativeto spouses'/ partners' wages. The Luxembourg Income Study archiveyields an unbalanced panel with 71 observations on 15 countries.The principal determinants of poverty reduction due to taxesand transfers are left government, constitutional veto points,and welfare generosity. The relative wage of women in couplesis a function mainly of female labor force participation, parttime work among women, and women's mobilization. In explainingthe causal pathways to these outcomes, we highlight the interrelationshipsof welfare state, care, and labor market policies.  相似文献

Infants often protest the activities of their caregivers, and this particular social interaction may provide an important window on early communication and its development. This study used naturalistic methods to investigate the development of vocal protests. Fifteen mother‐infant dyads at each of 5 ages, from 3 to 18 months, were observed at home. Maternal behaviors of caregiving and prohibiting were tallied from videotapes, as were infants' protests of these behaviors. Maternal caregiving decreased with age, but maternal prohibitions increased. There were no changes over age in the probability of protesting maternal caregiving behavior; however, 12‐month‐olds were more likely to protest prohibitions than 6‐ or 8‐month‐olds. Older infants were also more likely to use intense protests, such as screams, than younger infants. These age‐related changes were mirrored by the differences in prohibitions and protests observed between 8‐month‐olds who could crawl and those who could not. Findings from this study were related to previous research on infant crying as an important part of the prelinguistic communication system.  相似文献
