Reciprocal Family,Friendship and Church Support Networks of African Americans: Findings from the National Survey of American Life

This study examined reciprocal support networks involving extended family, friends and church members among African Americans. Our analysis examined specific patterns of reciprocal support (i.e., received only, gave only, both gave and received, neither gave or received), as well as network characteristics (i.e., contact and subjective closeness) as correlates of reciprocal support. The analysis is based on the African American subsample of the National Survey of American Life. Overall, our findings indicate that African Americans are very involved in reciprocal support networks with their extended family, friends and church members. Respondents were most extensively involved in reciprocal supports with extended family members, followed closely by friends and church networks. Network characteristics (i.e., contact and subjective closeness) were significantly and consistently associated with involvement with reciprocal support exchanges for all three networks. These and other findings are discussed in detail. This study complements previous work on the complementary roles of family, friend and congregational support networks, as well as studies of racial differences in informal support networks.     

一位法国人类学家在中国的田野实践——法国人类学家庄雪婵专访

庄雪婵副教授在访谈中谈到了其作为一名法国人类学家在中国进行田野实践的过程。在研究过程中,她深受法国人类学结构主义重要代表人物路易。杜蒙的影响,她运用杜蒙的“个人主义”理论对中国社会中的“个人”与“整体”关系进行了深入分析,她提出,在中国,虽然现代的音乐活动(如摇滚乐队)和传统的音乐活动(如“京剧票友”)在风格上截然不同,但是它们在结构上却存在着一定的相似性。另外,她也根据自己的跨文化研究经验,指出一个人类学家在田野中必须保持自己独立的思想、理性的思维,并做到不以自己的文化来衡量“他者”的文化。同时,她也对现代化进程中传统文化的急速消逝表现出了一个人类学家的忧虑,她呼吁人类学家应该尽快到乡村把这些濒临消逝的传统文化记录下来。     

A randomized,double-blind,placebo-controlled trial of testosterone gel on body composition and health-related quality-of-life in men with hypogonadal to low-normal levels of serum testosterone and symptoms of androgen deficiency over 6 months with 12 months open-label follow-up

Introduction: The clinical significance of low to low-normal testosterone (T) levels in men remains debated. Aim: To analyze the effects of raising serum T on lean body mass (LBM), fat mass (FM), total body mass, and health-related quality-of-life (HRQoL). Methods: Randomized, double-blind, placebo-controlled study. Men, aged 50–80 years, with serum total T<15 nmol/L and bioavailable T < 6.68 nmol/L, and a Aging Males’ Symptoms (AMS) total score >36, received 6 months treatment with transdermal 1% T gel (5–7.5?mg/day; n =183) or placebo gel (n =179), followed by 12 months open-label with T in all. Results: After 6 months, LBM increased in T- treated patients by 1.28?±?0.15?kg (mean ± SE) and FM decreased by 1.16?±?0.16?kg, with minor changes with placebo (LBM +0.02?±?0.10?kg and FM ?0.14?±?0.12?kg; all p < 0.001, T group vs. placebo). Changes were largely similar across subgroups of age, baseline total testosterone, and baseline BMI. Total HRQoL improved compared with placebo (p < 0.05, T group vs. placebo). Conclusions: Six months 1% T gel improved body composition and HRQoL in symptomatic men with low to low-normal T, with further improvements over the following 12 months.     

关于大学英语口语教学的一些认知思考

信息产业对大学英语教育显然有所冲击，而信息交流是大学英语教育的核心。从应用语言学理论我们可得出如下结论“口语习得的决定因素是语感”，针对学生在习得过程中存在的习得视窗误区，英语口语教学宜采用独有的语感训练方法，列出量化参考值。     

The ratio bias phenomenon: fact or artifact?

The ratio bias—according to which individuals prefer to bet on probabilities expressed as a ratio of large numbers to normatively equivalent or superior probabilities expressed as a ratio of small numbers—has recently gained momentum, with researchers especially in health economics emphasizing the policy importance of the phenomenon. Although the bias has been replicated several times, some doubts remain about its economic significance. Our two experiments show that the bias disappears once order effects are excluded, and once salient and dominant incentives are provided. This holds true for both choice and valuation tasks. Also, adding context to the decision problem does not alter this finding. No ratio bias could be found in between-subject tests either, which leads us to the conclusion that the policy relevance of the phenomenon is doubtful at best.     

In memoriam: L. H. M. Ling

In the early phase of its rule in Turkey (2002–4), the pro-Islamic government of the AKP (Justice and Development party) and various branches of the state collaborated in a series of political and economic reforms. The democratization process has gradually moderated and integrated Islamic actors into the secular Turkish Republic. However, it has also had polarizing effects on social groups. Among many, the polarization of two groups of women, ‘pious’ and ‘secularist’, deserves particular attention. Instead of bringing Turkish women together, gender reforms, particularly the lifting of the headscarf ban in universities, have divided women and created disarray and confrontation in society. This article reveals and compares the two dramatically different patterns of political engagement by pious and secularist women in leadership positions in contemporary Turkey. On the one hand, it reveals the increasingly radical backlash of secularist women against the increasing visibility in public spaces of pious women who veil. On the other hand, it examines how pious women, who see the tumult their religious observance in the public space is creating, are increasingly turning to a non-confrontational mode of non-response. What is the prognosis for the future of a democratic Turkey?
