Differences in Emerging-Adult Women's Body Image and Sexuality Outcomes According to BMI and Dating Status

ABSTRACT. Emerging adulthood is a crucial time for the development of body image and sexuality concerns among women. We collected self-reported data from 184 women to determine possible differences according to body mass index (BMI) classification and dating status. Multivariate analyses of variance and follow-up univariate analyses of variance were conducted to determine differences in body image and sexuality outcomes according to both BMI (normal weight vs. overweight) and dating status (dating vs. not dating) as well as interaction effects of BMI and dating status. First, results indicated differences between normal-weight and overweight women for body satisfaction, body self-consciousness, and body image avoidance. Overweight women had lower satisfaction, higher self-consciousness, and more avoidance. Differences were also found between women who were dating and those who were not dating for body satisfaction and self-consciousness: Women not dating had lower satisfaction and higher self-consciousness. Second, whereas results indicated that women of varying BMIs did not differ on sexuality outcomes, differences were found according to dating status for sexual attitudes, esteem, and self-schema, such that women not dating had more conservative sexual attitudes, less sexual esteem, and lower self-schemas. No significant interaction effects were found.     

Classroom Approach for Managing Dietary Restraint,Negative Eating Styles,and Body Image Concerns Among College Women

Objective: In this exploratory study, the authors evaluated the impact of an elective college course on dieting levels, eating styles, and body image among college women. Participants: Participants were a convenience sample of 29 self-selected female students at a western university who were mostly white, normal-weight seniors with significant dieting experience. Methods: The authors used valid and reliable instruments to collect data both before and after testing. An instructor conducted the program in an undergraduate course that met twice weekly for 15 weeks. Theory-based lessons focused on resisting media pressure, modifying dietary restraint, eating in response to hunger (intrinsic eating), and achieving healthy body image. Dependent variables included intrinsic eating, dieting involvement, emotional eating, body image, and self-esteem. Results: A comparison of pretest and posttest scores identified significant improvements for most measures. Conclusions: A theory-driven elective course implemented within a college setting may improve women's eating styles and body image.     

Exploring the essence of enabling child participation within child protection services

The chances that children have to participate in child protection services are largely contingent upon the attitudes and skills of case managers. They have a crucial role in ensuring that a child's voice is being listened to and acknowledged in often sensitive dialogues. Therefore, the aim of this study is to investigate what case managers need to facilitate child participation. By handing case managers a participation toolbox developed by children and through the use of reflexive monitoring in action, we elaborated on the barriers faced in practice. The results show that the intention to facilitate child participation is quickly overruled by often subconscious thoughts and beliefs, stemming from the complex interplay of child image, protection, and participation. Case managers need to be aware of this interplay and how this unknowingly steers their actions. Therefore, iterative reflection should be facilitated within organizations for an actual change in their daily practice and to amplify the role of children in the decision‐making processes within child protection services.     

左江花山岩画铜鼓考

左江花山岩画文化景观成功入选世界遗产名录后,依然有未解的千年之谜。经对左江花山岩画中铜鼓的族属、类型、传承发展、文化功能等进行多角度考证,确认左江花山岩画所绘铜鼓为骆越人所有,其类型为万家坝型、石寨山型和东山型早期铜鼓;岩画中的铜鼓不仅是部族首领权力的象征,还是通天礼神、汇聚人心、指挥军阵、人神共娱的重要礼器、响器及乐器;东汉马援缴骆越铜鼓后,左江流域骆越后裔仍有用鼓、尚鼓的习俗,这是对左江花山岩画铜鼓的一种继承与发展。与此同时,骆越人先进的青铜铸造技术亦为铜鼓在这一地区的传承与发展提供了物质基础。     

“抖音”上的个体形象建构与对社会价值观的呼应——兼论书写“抖音”微生活民族志的可能性

人们构建形象、呈现自我的方式在自媒体时代不断发生着转变,这是人类学家不得不关注的现象。赵旭东教授指出,“微信民族志”时代已经到来。本研究认为,“抖音”作为当代青年中最具影响力的短视频平台,可以拓展微信民族志研究,但怎样开展“抖音”微生活民族志研究尚无一些有创建的尝试。本研究首先分析了书写“抖音”微生活民族志的可能性,进而厘清了研究对象,且以此为基础,对“抖音”微生活民族志进行了一种探索性的书写,试分析“抖音”短视频对个体形象建构的主观和客观影响。研究发现,短视频内容文本的反复强化特点促使个体有效建构自我形象;在个体不主动避讳被熟人观看时,他们的线下形象与线上形象基本吻合;看似是网民共同主动筛选出来的网红,实则是当前社会价值观的反映。
