Feminist thought in transition: Never a dull moment

In this essay, I summarize how I believe feminist thought has developed during the period 1960–2000 and where it might go in the future. First, I summarize the evolution of second-wave feminist thought during the period from the early 1960s to the late 1980s, focusing on liberal, radical, and Marxist–socialist feminisms. Next, I summarize multicultural, global, and postmodern feminisms as they emerged in the U.S. and elsewhere during the late 1980s and early 1990s, viewing them as a transition from second-wave to third-wave feminist thought. Third, I claim that young women today, including those who are doing feminism in the manner of third-wave feminists, are shaping a very particularistic, even individualistic form of feminism, with mixed consequences. Fourth, I will conclude that the future of feminist thought depends on its ability to resolve the sameness–difference debate, for unless women and the category of gender have some role to play in feminism, it is not clear that labeling one's self a “feminist” makes sense anymore.     

疾病与时尚的观念交织——医疗社会史视角下的民国成都娼妓及其日常生活

民国成都的娼妓数量众多,性病的社会传染问题特别突出?在各种性病治疗方式中,西医的九一四标准化治疗以其有效性与方便性,成为社会认同的最优治疗方案?娼妓?性病与九一四等性病药品建构了普遍认知中的娼妓生活?与此同时,脂粉?美容药品与时髦穿着等符号表征,又建构着娼妓生活的另一个面相?娼妓的“疾病”与“时尚”,对于宏大的历史来说,只是一个小小的碎片,但是对于历史的整体重构却有重要意义?     

课程外活动对大学生就业力的影响——基于第三期中国妇女社会地位调查之女大学生群体调查数据

随着大学生就业问题的日趋凸显,就业力的培养和储备成为政府相关部门和学术界的核心议题之一.基于第三期中国妇女社会地位调查之女大学生群体调查数据,以结构方程的方法对参与课程外活动与大学生就业力培养之间的关系进行研究,显示参与课程外活动对提高就业力具有显著影响.此外,大学生参与课程外活动还借由社会支持为中间变项,间接影响就业力水平.而与人们日常生活中的观点不同,本研究发现学业成就对就业力的影响未达到显著性水平,这对于传统的单纯强调课程内学习和专业成绩的价值观念形成了挑战.     

小型CO2热泵系统的搭建与性能研究

天然工质CO2以其优良的热物理性能和友好的环境特性成为热泵系统中运行工质最有潜力的替代物之一。为了加快CO2作为制冷剂向实用化产品迈进,采用CO2作为制冷剂,确定了跨临界C02热泵系统方案及工况,对气体冷却器、蒸发器及辅助部件进行了选型设计,并最终搭建了一个带回热器的跨临界C02热泵系统实验台,该试验台结构紧凑,制造、运行成本较低。同时文章中就冷却水、冷冻水对系统性能的影响做了初步研究。研究表明：提高冷冻水流量对提高热泵出水温度的影响很小;提高冷却水流量可以有效提高能效比EEER,并对制取高温热水有很大帮助,但是同时会增加流动阻力。     

Mainstream Discourse and the Construction of Public Understanding of Women's Employment

1949年后在妇女就业知识上存在着三种主流话语。一是计划经济时代，妇女就业知识以“革命话语”来叙述，实现了对妇女参加公共领域劳动的动员；二是从计划经济向市场经济转型的过程，妇女就业知识是以“素质话语”被叙述的，其在力图将妇女推回家庭领域的过程中压低了女性劳动力的价格；三是市场化时代，妇女就业知识以“男性强势话语”被表述，显示了市场经济与父权制的有机结合。与此同时，有关妇女就业知识的女性主体性也在形成，它显示出女性自主意识及其对人权话语的使用。

关键词: 革命话语素质话语男性强势话语

There have been three types of mainstream discourse relating to public understanding of women's employment since the founding of the People's Republic of China in 1949. The first was the “revolutionary discourse” that dominated the era of the planned economy. During this period, knowledge about women's employment was heavily influenced by revolutionary discourse, and women were mobilized to take up positions in virtually all areas of social life. The second occurred in the transition from a planned to a market economy. During this process, knowledge of women's employment was constructed by a so‐called “quality discourse,” which depressed women's wages in the course of driving them back into the home. The third important mode of discourse took place in the era of marketization, and saw knowledge about women's employment constructed by male‐centered hegemonic discourse in an organic union between the market economy and the patriarchal system. Meanwhile, female subjectivity in regard to knowledge about women's employment is taking shape. At the same time, women's sense of autonomy in relation to understanding of employment has started to grow and exhibits self‐awareness and use of the discourse of human rights.     

Media reputation in initial public offerings: A study of financial news coverage in Hong Kong

This study investigated media reputation in initial public offerings (IPOs) by proposing eight attributes of substantive media reputation from environmental and product-resource perspectives. A content analysis on financial news coverage (2281 newspaper articles from 2004 to 2010) in Hong Kong was conducted to examine how print media reported financial and nonfinancial information on 38 IPO firms in the sectors of financial, properties and construction, and consumer goods. Results from partial least squares analysis showed that, although substantive media reputation and recency of news coverage together only explained a small proportion of changes in IPO share price, substantive media reputation has a significant positive effect on changes in IPO share price. Apart from the significant positive effect from the presentation tone of environmental attributes, the tone of social attributes had a significant negative effect on substantive media reputation. With the increasing concern on measuring media reputation attributes in financial news coverage across different contexts, this study contributes to the applicability of environmental and product-resource attributes in the specific context of IPOs.     

Nonparametric bootstrapping for hierarchical data

Nonparametric bootstrapping for hierarchical data is relatively underdeveloped and not straightforward: certainly it does not make sense to use simple nonparametric resampling, which treats all observations as independent. We have provided some resampling strategies of hierarchical data, proved that the strategy of nonparametric bootstrapping on the highest level (randomly sampling all other levels without replacement within the highest level selected by randomly sampling the highest levels with replacement) is better than that on lower levels, analyzed real data and performed simulation studies.     

政府购买社会组织公共服务的风险防范措施

政府购买公共服务的风险存在于购买的全过程,针对每个环节的潜在风险因素提出相应的风险防范措施,有助于促进政府购买公共服务的健康可持续发展.计划环节,应着重强化政府的购买责任意识、健全政府购买公共服务的法律法规;甄选环节,重在规范购买程序、增强社会组织使命感;实施环节,则应从建立健全监督机制、提升社会组织公信力着手;评价环节,则重在完善政府购买的绩效评估体系、引入第三方评估等.
