NETWORKING CAPITALISM: Network Construction and Control Effects In Direct Selling

Drawing on a qualitative study of direct selling in Taiwan, this article examines the process of network construction and its control effects over distributors. I found that weak ties, rather than strong ties, constitute major networks for distributors to expand their business. In order to consolidate trust within weak ties, distributors develop two major strategies: personalizing sales and familiarizing sponsorship. They are engaged in a multilevel performance of emotional labor in facing the audience of customers and fellow distributors. Social networks not only function as a facilitator of economic exchange but also become a meáns of labor control that permeates both public and private lives of distributors.     

青少年性教育的有效抓手：同伴性教育

通过对我国青少年性教育现状的分析,发现父母和老师都没能很好地承担起青少年性教育的重任,造成这一状况的一个重要原因是两代人之间存在着沟通障碍.这就需要大力推广以同辈群体的影响力为基础的同伴性教育.     

ETHNICITY, GENERATION, AND SCHOOL ATTAINMENT OF ASIANS, HISPANICS, AND NON-HISPANIC WHITES

Research on immigration and attainment in U.S. schools typically does not separate out generation of U.S. residence, a critical factor in attainment. This article explores immigrant generation effects (native, child of immigrant, immigrant) on schooling attained for Asians, Hispanics, and non-Hispanic whites, using Current Population Survey data. Previously unpublished cross-sectional data are presented. Regressions predicting school years completed show variable generation-by-ethnicity effects. Asian attainment increases sharply between immigrant and child-of-immigrant generations, leveling off thereafter. Hispanic attainment improves with successive generations of U.S. residence. Non-Hispanic white attainment peaks in the child-of-immigrant generation and declines for later generations.     

Exposure Reconstruction for the TCDD-Exposed NIOSH Cohort Using a Concentration- and Age-Dependent Model of Elimination

Recent studies demonstrating a concentration dependence of elimination of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) suggest that previous estimates of exposure for occupationally exposed cohorts may have underestimated actual exposure, resulting in a potential overestimate of the carcinogenic potency of TCDD in humans based on the mortality data for these cohorts. Using a database on U.S. chemical manufacturing workers potentially exposed to TCDD compiled by the National Institute for Occupational Safety and Health (NIOSH), we evaluated the impact of using a concentration- and age-dependent elimination model (CADM) (Aylward et al., 2005) on estimates of serum lipid area under the curve (AUC) for the NIOSH cohort. These data were used previously by Steenland et al. (2001) in combination with a first-order elimination model with an 8.7-year half-life to estimate cumulative serum lipid concentration (equivalent to AUC) for these workers for use in cancer dose-response assessment. Serum lipid TCDD measurements taken in 1988 for a subset of the cohort were combined with the NIOSH job exposure matrix and work histories to estimate dose rates per unit of exposure score. We evaluated the effect of choices in regression model (regression on untransformed vs. ln-transformed data and inclusion of a nonzero regression intercept) as well as the impact of choices of elimination models and parameters on estimated AUCs for the cohort. Central estimates for dose rate parameters derived from the serum-sampled subcohort were applied with the elimination models to time-specific exposure scores for the entire cohort to generate AUC estimates for all cohort members. Use of the CADM resulted in improved model fits to the serum sampling data compared to the first-order models. Dose rates varied by a factor of 50 among different combinations of elimination model, parameter sets, and regression models. Use of a CADM results in increases of up to five-fold in AUC estimates for the more highly exposed members of the cohort compared to estimates obtained using the first-order model with 8.7-year half-life. This degree of variation in the AUC estimates for this cohort would affect substantially the cancer potency estimates derived from the mortality data from this cohort. Such variability and uncertainty in the reconstructed serum lipid AUC estimates for this cohort, depending on elimination model, parameter set, and regression model, have not been described previously and are critical components in evaluating the dose-response data from the occupationally exposed populations.     

媒介再现父职：“新父亲”形象与父职教育契机——基于网络短视频的内容分析

随着网络短视频在日常生活中的广泛渗透,以“爸爸带娃”为主题的家庭父职生活也逐渐媒介化。以微信视频号、小红书和抖音三大主流网络平台的短视频为研究对象,采用内容分析法,探究媒介再现父职中的“新父亲”形象,以及媒介再现父职隐含的父职教育契机。研究发现：媒介再现父职以“关爱父职”为主导,关爱父职影响积极且效果良好;父亲参与意愿和参与主动性强;父亲参与的互动性较为充分;平等、亲和、睿智的父亲形象突出;引流变现下的“花式带娃”等多样化“新父亲”形象。鉴于网络传播的巨大影响力和实效性,媒介再现父职的促进路径为：推动新父职理念的传播与实践转向;设立常人榜样,实现父职教育的日常渗透;明确本土化父职研究方向,拓展父亲情感参与维度。

债权治理与盈余质量:来自中国证券市场的经验证据

以2007-2008年非金融类上市公司为样本,研究了债权治理与盈余质量之间的关系,得到以下研究结论:资产负债率与盈余质量显著负相关,短期资产负债率与盈余质量显著负相关,长期资产负债率与盈余质量呈现出不显著的正相关关系。进一步研究后发现,短期债务融资是引发盈余质量恶化的主要原因,而长期债务融资虽然一定程度上改善了上市公司的盈余质量,但这种效果总的来说并不显著。此外,最终控制人的国有性质加剧了债务契约引发的盈余管理动机,恶化了盈余质量。     

蔡元培的美育思想与西方美学

蔡元培美学思想作为他教育思想的重要组成部分,是他批判地继承了中国传统文化中的合理内容,吸收了康德、席勒等西方先进美学思想,并加以创新的产物。他以审美的普遍性和超脱性为理论依据,将其美学思想结合到培养完善健全人格和改造社会的实践中,对中国近代教育产生了积极而深远的影响。     

我国老年人临终前需要完全照料的时间分析

根据中国老年人健康长寿影响因素2005年第4周期调查数据,用多水平随机效应序列模型,对中国65岁及以上老年人临终前需要他人完全照料的天数进行较为系统的分析。结果显示照料时间与杜区社会经济发展因素无很大关联性,但与性别、受教育程度、有病及时治疗、子女可近度、经常参与宗教佛事活动和基期健康等个体因素存在一定依存关系。
