Local trade in non‐timber forest products (NTFPs) is increasing globally, yet the causes have been little studied. We examine household shock as a driver of NTFP trade in five southern African countries, with an emphasis on HIV/AIDS‐related illness and death. Over the past two years, 95% of trader households experienced at least one shock, with family illness and death recorded for 68% and 42% of households, respectively. Almost 40% had entered the trade because of HIV/AIDS‐related shocks. Additional shocks included natural disasters, crop pests or failure and livestock loss. The sale of NTFPs was the third most common coping strategy, after kinship and agricultural adjustments. Coping strategies differed between sites and type of shock.  相似文献

The paper investigates the curious case of the Hungarian Count(ess) Sarolta/Sándor Vay, journalist and writer, but, above all, a notorious gender bender in late nineteenth-century Austro-Hungarian Monarchy. The article examines her case in the context of the history of European cross-dressing and of narrative transvestism. The author argues that nineteenth-century dandyism provided an effective cultural framework for Vay’s contemporaries to accept her unconventional presence in fin-de-siècle Hungarian society. Moreover, she claims that Vay’s narrative transvestism may also be construed within the cultural phenomenon of dandyism, as her writing practices prove to be further instruments for her self-fashioning. Finally, she concludes that Vay’s gender performance and narrative transvestism become illustrative examples of instances that both frame and confuse accepted cultural patterns, destabilize gender binarism, and participate in its maintenance.  相似文献

There is widespread concern that episodes of unemployment and unstable working conditions adversely affect health. We add to the debate by focusing on the relationship between work trajectory and the self-reported health of Italian men and women during the present economic downturn. Relying on Italian data in the EU-SILC project (from 2007 to 2010), our sample includes all individuals aged 30 to 60 in 2010, and uses multivariate binomial regression models for preliminary analyses and the Structural Equations modelling (SEM) to observe the cumulative effects of health status according to different job trajectories. Our main findings show similar pictures for men and women. Individuals who are unemployed, ejected or in precarious occupational positions have a higher risk of worsening their health status during these years.  相似文献

Religious disaffiliation—leaving the religious tradition in which one was raised for no religious affiliation in adulthood—has become more common in recent years, though few studies have examined its consequences for the health and well-being of individuals. We use an innovative approach, comparing the health and subjective well-being of religious disaffiliates to those who remain affiliated using pooled General Social Survey samples from 1973 through 2012. We find that religious disaffiliates experience poorer health and lower well-being than those consistently affiliated and those who are consistently unaffiliated. We also demonstrate that the disadvantage for those who leave religious traditions is completely mediated by the frequency of church attendance, as disaffiliates attend church less often. Our results point to the importance of the social processes surrounding religious disaffiliation and emphasize the role of dynamics in the relationship between religious affiliation and health.  相似文献

In this paper, we demonstrate how public opinion surveys can be designed to collect information pertinent to computational behavior modeling, and we present the results of a public opinion and behavior survey conducted during the 2009–2010 H1N1 influenza pandemic. The results are used to parameterize the Health Belief Model of individual health‐protective decision making. Survey subjects were asked questions about their perceptions of the then‐circulating influenza and attitudes towards two personal protective behaviors: vaccination and avoidance of crowds. We empirically address two important issues in applying the Health Belief Model of behavior to computational infectious disease simulation: (1) the factors dynamically influencing the states of the Health Belief Model variables and (2) the appropriateness of the Health Belief Model in describing self‐protective behavior in the context of pandemic influenza.  相似文献

Integrating volunteers into social care is widely expected but rarely successful in practice. This paper discusses how the Community Care Centre Plan organising community volunteers to provide services to the elderly in Taiwan. This plan successfully integrated social workers and volunteers in a national system to offer service in local communities, showing a systemic practice of community care and a unique case of community-based and volunteer-based service. The purposes of this paper are to introduce the programme design and to understand how to integrate the mission of social workers and volunteers’ performance. The governmental policy and requirements, the role of social workers and the provision of voluntary community service which contributed to form the system were examined in this paper.  相似文献

This paper examines narratives about fatness that are represented and reproduced by the character of “Fat Monica” played by Courteney Cox in a fat suit on the sitcom Friends. By drawing on David T. Mitchell's framework for analyzing “narrative prosthesis,” I examine how Fat Monica's narratives on Friends represent complex intersections of identities. I argue that fat suits often evoke fatness to support limited and clichéd narratives; however, fat suits may also enable new means of representing and understanding fatness. Through an analysis of the ways in which Fat Monica is represented in the episodes she appears in, three key uses of Fat Monica's fatness are discussed. Firstly, I examine the comic uses of Fat Monica and their relationship between fatness and humour. Next, I examine how Fat Monica storylines represent interlocking narratives of fatness, femininity, and sexual desire. Lastly, I consider how Fat Monica represents the construction of the normative body and claims about fatness and authenticity. Ultimately, Fat Monica illustrates how fatness relates to understandings of humour, gender, social class, and heterosexuality.  相似文献

ABSTRACT

African American adolescents continue to be disproportionately impacted by HIV, sexually transmitted infections (STIs), and unanticipated pregnancies. In-depth, face-to-face interviews among a convenience sample of 32 African American adolescents (16 male and 16 female) were used to explore the reasons why some adolescents decided to engage in sex while others chose to delay sexual debut. Data were analyzed using a thematic analysis. Among the overall sample, psychological motivations, external pressure, physical pleasure seeking, and relationship-related motivations were the major themes cited for engaging in sex by participants and their friends. External support, motivation to avoid negative consequences, not feeling ready or lacking interest in sex, and having negative views about sex were among the major reasons for delaying sex. Several of the emergent themes showed gender differences. Suggestions for future research include the need for sexual education, and STI/HIV prevention programs that are gender sensitive and flexible enough to accommodate multiple factors related to sexual debut.  相似文献

Abstract

The present study examined the health status and outpatient health care utilization among 52 adults with severe or profound intellectual disabilities (IDs) living with their families or in group homes in New York City. Bivariate and regression analyses among demographic variables, medical conditions, health care utilization, and type of living situation were conducted. Findings indicate that demographic factors andhealth statuses were similar regardless of living situation, except for ageand the presence of Down Syndrome, that is, younger people and people with Down Syndrome were more likely to live with family than in group homes. The results indicated that regardless of where they lived, individuals had high rates (70%) of overweight/obesity. The mean number of internal medicine, specialty medicine, nursing, and total clinic visits were significantly higher for those living in group homes compared to those living with their families. The findings and their implications are discussed with respect to social work policy and practice.  相似文献
