Adaptations are psychological and behavioral mechanisms designed through evolution to serve specific purposes ultimately related to reproductive success. Although adaptations are inherently functional, in some cases their operation can nevertheless cause personal and social dysfunction. We describe a theoretical framework for understanding, predicting, and reducing the dysfunctional consequences of psychological adaptations. We discuss three general sources of dysfunction: a) the existence of adaptive tradeoffs, b) mismatches between current environments and ancestral environments, and c) individual differences. The paper applies this framework primarily to the topic of social anxiety, a psychological phenomenon marked by concerns pertaining to social rejection and embarrassment. Although social anxiety can serve useful functions, it can also involve excessive worry, negative affect, and avoidance of social situations, leading to significant distress and social impairment. We consider sources of dysfunction in social anxiety and discuss implications for policy, including recommendations for psychological, situational, and biological interventions. We also discuss broader applications of this theoretical framework to other areas of social life.  相似文献

This study tested a series of models predicting household expectations of participating in hurricane hazard mitigation incentive programs. Data from 599 households in Florida revealed that mitigation incentive adoption expectations were most strongly and consistently related to hazard intrusiveness and risk perception and, to a lesser extent, worry. Demographic and hazard exposure had indirect effects on mitigation incentive adoption expectations that were mediated by the psychological variables. The results also revealed differences in the factors affecting mitigation incentive adoption expectations for each of five specific incentive programs. Overall, the results suggest that hazard managers are more likely to increase participation in mitigation incentive programs if they provide messages that repeatedly (thus increasing hazard intrusiveness) remind people of the likelihood of severe negative consequences of hurricane impact (thus increasing risk perception).  相似文献

Abstract

After reviewing the major changes taking place in American higher education, the present paper discusses a select number of challenges confronting US social work education. These challenges are broadly characterized as those of rigor and relevance. The paper presents the author's reflections on the best ways to meet these challenges and stresses the promotion of research and social innovations as important foci for social work education.  相似文献

Poverty has increased significantly in U.S. suburbs since the 1990s. What we know about suburban poverty is largely limited to demographic and economic information. Building off the organizational perspective approach, I use in‐depth interviews with nonprofit, antipoverty organizations in eight Pennsylvania suburbs to better understand the suburban poverty experience. My focus is on how organizations compete for external resources. By working directly with the poverty problem while also working in broader metropolitan political and economic fields of decision making, this “middleman” role ( Marwell, 2007 ) gives us insights into contemporary poverty dynamics for suburbs. I find that how suburban organizational leaders perceive the challenges they face, and what strategies they adopt to confront such difficulties, revolves around symbolic dilemmas posed by the history, distribution, and politics of poverty in the suburbs. Symbolic dilemmas cluster around three different situational contexts of poverty in the suburbs. I use this to develop a three‐part typology of suburban poverty: symbiotic suburbs, skeletal suburbs, and overshadowed suburbs. This typology has implications for future research and for policymakers interested in developing tools to appropriately address this pressing issue.  相似文献

L'État providence Canadien est déséquilibré: leader mondial dans certains domaines de l'investissement social—plus particulièrement en soins de santé et enseignement supérieur—il traîne dans d'autres domaines de la dépense d'aide sociale, y compris les politiques de garde d'enfants. Nous constatons qu'aujourd'hui la résistance dans la plupart des régions du Canada à la politique de garde d'enfants universel a des racines historiques profondes. Elle est de fait intégré dans le cadre même du bien‐être social canadien: le contrat de citoyenneté sociale. Nous employons une approche de “bas en haut” sur l'état du bien‐être en nous concentrant sur la façon dont les acteurs collectifs, en particulier, les féministes de la première vague et leurs contemporains au sein des organisations du mouvement ouvrier, ont encadrées et caractérisé la citoyenneté sociale féminine; Nous constatons que l'exclusion de l'adhésion des femmes employées tronque les possibilités discursives par lesquelles des revendications pour des provisions universelles de bien‐être sociale pourraient être apportées. Canada's welfare state is lopsided: while leading the world in some areas of social investment—most notably health care and higher education—it is a laggard in other areas of social welfare spending, including childcare policies. We find that policy resistance to universal childcare in most regions of Canada today has deep historical roots and is, indeed, embedded into the very framework of the Canadian welfare state: the social citizenship contract. We employ a “bottom‐up” perspective on the welfare state focusing on how collective actors, in particular, first‐wave feminists and their contemporaries within labor movement organizations, framed and characterized female social citizenship in ways that excluded employed women from full membership and, in this, truncated discursive opportunities by which claims for universal welfare state provisions could be made.  相似文献

In this essay, focusing primarily on the cinema of the walking corpse, I provide an overview of zombie studies and suggest potential avenues for sociological inquiry into zombie phenomena. I argue that zombie films, comic books, novels, video games, and the like can be seen as significant cultural objects that reflect and reveal the cultural and material circumstances of their creation. Despite emanating from complex culture‐producing institutions and (arguably) capturing extant social anxieties, sociology has remained quiet on zombie phenomena. Issues of significance, history, and definition are discussed. I then locate three avenues of inquiry ideally suited to the sociological toolkit: symptomatic analysis of content, production, and audience response and interaction. I conclude by calling for a multipronged sociological analysis into “zombie culture.”  相似文献

This essay identifies ten significant methodological challenges for understanding aggression and gender. In light of the recent explosion of research on indirect/relational/social aggression, it seems important to clarify gaps in our current understanding and to identify promising methods by which better answers might be found. The discussion begins with basic issues of definitions, contexts and subtypes, moves on to points concerning sampling and measures, and addresses whether current evidence warrants deciding that girls are as aggressive as boys. We conclude that although research has shown that the majority of girls' aggression takes indirect/relational/social forms, it is premature to conclude that boys do not also engage in these behaviors. We caution against assuming that physical and indirect/relational/social aggression are comparable in their developmental origins and consequences, and urge researchers to consider that fully understanding indirect/relational/social aggression might require different conceptual frameworks and research methods.  相似文献

The purpose of this study was to examine the validity of a new procedure for assessing infant-mother attachment. Sixty children (34 in child care) and their mothers were seen in the Strange Situation (SS) at 17 months and in a new attachment assessment, the California Attachment Procedure (CAP), which does not involve mother-child separations, at 18 months. Overall, children were more likely to be classified as secure in the CAP (83% vs. 67%), but this was particularly true for children with experience in routine nonmaternal care. Of the children in nonmaternal care who were insecure in the SS, 91% were secure in the CAP, whereas of the maternal-care children who were insecure in the SS, only 44% were secure in the CAP. Attachment security in the CAP was more highly correlated with observed maternal sensitivity than was attachment security in the SS, particularly for children in nonmaternal care.  相似文献
