氧化还原机制在中医体质研究中的应用

[摘要]氧化还原平衡体现了阴阳平衡思想,氧化还原机制与体质学基本原理及体质三级预防理念有着相似之处,氧化还原机制的多样性研究为体质分类研究提供了切入点。对不同体质的人群进行氧化还原状态检测,一方面可诠释体质理论的科学内涵,另一方面可为“治未病”提供可供参考的指标体系。     

The Peer Appearance Culture During Adolescence: Gender and Body Mass Variations

The purpose of this research was to examine gender and body mass, as factors linked to perceived experiences within the peer appearance culture. The sample included 215 girls and 200 boys who were either in 7th grade or 10th grade. Students provided self-reports on experiences in three domains: appearance culture among friends (appearance conversations and diet/muscle talk), peer evaluations (peer appearance pressure, appearance teasing, and vicarious peer teasing), and peer acceptance concerns (appearance-based acceptance, peer appearance comparison). The results indicated that although girls reported more appearance conversations, boys perceived more appearance pressure and teasing. Boys also admitted that they talked with friends about muscle building at a rate greater than girls talked about dieting. BMI showed distinct gender patterns. BMI was a key attribute that unified the experiences within the appearance culture for overweight girls. Among the boys, BMI was associated with differentiated experiences for underweight and overweight participants.Associate Professor in Educational Psychology at the University of Washington.

Body Image Concerns in Young Girls: The Role of Peers and Media Prior to Adolescence

Peer and media influences have been identified as important conveyors of socio-cultural ideals in adolescent and preadolescent samples. This study aims to explore peer and media influences in the body image concerns and dieting awareness of younger girls, aged 5–8 years. A sample of 128 girls was recruited from the first 4 years of formal schooling. Individual interviews were conducted to assess the aspects of body image, as well as dieting awareness by means of a brief scenario. A number of sources of peer and media influence were examined. It was found that by 6 years of age, a large number of girls desired a thinner ideal figure. Both peer and media influences emerged as significant predictors of body image and dieting awareness. Specifically, girls’ perceptions of their peers’ body dissatisfaction predicted their own level of body dissatisfaction and dieting awareness. Watching music television shows and reading appearance-focused magazines predicted dieting awareness. In particular, girls who looked at magazines aimed at adult women had greater dissatisfaction with their appearance. Thus, the present study highlights that girls aged 5–8 years of age are already living in an appearance culture in which both peers and the media influence body image and dieting awareness.Hayley Dohnt, B.

The Skinny on Body Dissatisfaction: A Longitudinal Study of Adolescent Girls and Boys

The present study tested whether theoretically derived risk factors predicted increases in body dissatisfaction and whether gender moderated these relations with data from a longitudinal study of 428 adolescent girls and boys because few prospective studies have examined these aims, despite evidence that body dissatisfaction increases risk for various psychiatric disturbances. Body dissatisfaction showed significant increases for girls and significant decreases for boys during early adolescence. For both genders, parental support deficits, negative affectivity, and self-reported dietary restraint showed significant relations to future increases in body dissatisfaction. Ideal body internalization and body mass index did not demonstrate significant relations to future increases in body dissatisfaction; peer support deficits showed a marginal relation to this outcome. Gender did not moderate these relations, despite adequate power to detect interactive effects.

Factors Contributing to Gender Differences in Depressive Symptoms: A Test of Three Developmental Models

In a longitudinal study on 115 early adolescents, the impact of major events, relationship stressors, and coping style in interaction with biological changes on depressive outcome in late adolescence were explored. Three developmental models proposed by Nolen-Hoeksema and Girgus (1994, Psychol. Bull. 115: 424–433), which attempt to explain the emergence of gender differences in adolescent depressive symptoms, were tested. Multiple regression analyses conducted to test Model 1 identified two etiological factors associated with gender differences of depression, namely, stress in the adolescent–mother relationship and a more negative body image. Tests of Model 2 revealed etiological factors which correlated with depression in adolescent girls but not adolescent boys. The correlational patterns of avoidant coping and body image emerged as relevant factors for Model 2. Finally, tests of Model 3 searched for factors which were more likely to be observed in adolescent girls than boys and which would put girls at risk should they interact with a third etiological factor. Early maturational timing emerged as a factor for Model 3.     

同一个体发毛角蛋白电泳谱型的分析

用SDS -PAGGE对收集到的 2 0例人体表毛发 (头发、阴毛、腋毛、腿毛 )角蛋白组分进行了分析。结果表明 ,同一个体毛发角蛋白电泳谱型基本相同 ,用激光光密度仪对电泳凝胶板扫描后证实 ,同一个体毛发角蛋白组分相对百分含量也无明显差异 ;人头部不同部位 (顶部、左侧、右侧、额部、枕部 )头发角蛋白的电泳谱型和角蛋白组分相对百分含量也基本相同。同一个体毛发角蛋白组分的分析 ,可为法医物证学鉴定中的毛发个人识别提供重要的依据。

能动司法的实现条件——一个中美比较的视角

近年来,司法能动作为一种与司法克制相对的司法意识形态,引起国内法学界和实务界的关注,很多学者和法官倡导在司法实践中应该充分发挥法官的自由裁量权,实行＂能动的司法＂。但是,能动司法的实现需要多方面条件和因素来支持,否则实行能动司法于法治是不利的。通过比较中美两国在法律文化、法律制度等方面的差异,分析美国能动司法的实现条件,发现中国的不足,有利于推动中国实行有限的＂能动司法＂,构建和谐的法治社会。     

论ICSID仲裁庭对视为外国法人管辖权的扩张

国际投资争端仲裁管辖权是解决投资争端国际中心机制的重要内容,是"中心"仲裁庭进行仲裁的前提条件,具有重要的实践和理论意义。对于视为外国国民投资者管辖权问题,《公约》规定的较为模糊和弹性,近年来,"中心"做扩大解释,导致与此相关的仲裁实践中出现扩张性管辖案例,直接挑战"中心"现有的运行机制,这种扩展性管辖在南美等一些国家甚至有泛滥的趋势,对发展中国家经济发展带来极大负面效应。深入剖析和评价这一现象,并提出我国的应对策略,具有重要的现实意义。     

差异性社会:基于政治学层面的思考

差异性社会是对我国经济社会发展现状的客观定位。其中,尊重人的主体性地位是差异性社会形成的基点;规范人的主体性行为是差异性社会的制度要求;提高人的劳动能力是差异性社会的基本任务。从政治学层面梳理差异性社会理论对构建社会主义和谐社会以及人的全面发展有一定意义。
