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

华北油田是我国最早发现古潜山海相碳酸盐岩油气藏的地方,也是产量骤起骤降幅度最大的一个油田,它的勘探过程中蕴含着太多丰富的经验值得总结.从任4井发现的细节入手进行回顾,对华北油田勘探经验中的古潜山、碳酸盐岩、震旦系灰岩等关键问题进行了深入思考.指出按有机成油论的学说很难将华北油田的历史经验深入总结下去,应按无机成油论的观点,对华北油田的历史经验进行再认识. 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

本文以生命历程理论为研究视角,以深度访谈的方法收集老年人“主诉”的关于过去的生活资料,试图通过对个人能动性与生命历程时间性的强调,来分析个体生命历程与社会变迁的相互嵌入过程,以及这一过程中不断分化的内部机制。研究发现,老化的过程是一个随时间推移不断累积与分化的过程,累积因素的先后顺序对个体之间的分化具有重要意义,累积是生命历程资本遭遇生命历程风险的结果,是社会结构与个人能动性相互作用的动态过程,其中社会政策的变迁对累积过程具有决定性的影响。 相似文献
