论中国二十年代的性教育思想

性教育是二十年代思想界教育界热门话题之一.当时一些知识分子破除传统的性卑污、性忌讳、性神秘心态,积极倡吁性教育,他们对性教育的必要性与迫切性、任务与宗旨、方式与内容等方面进行了较为深入的探讨,形成了比较完整的性教育思想.这一思想不仅有其形成的历史必然性,而且在近现代性教育思想史上具有不可抹杀的地位,对当代中国性教育的理论和实践也不失其价值.     

狂气、病迹学与文学创作——兼论日本文学病迹学研究

病迹学是19世纪末发展起来的以精神医学为基础的一门边缘性学科。它以杰出人物(特别是艺术家)为对象,从精神医学的角度分析探究他们的异常性格、内心纠葛、病理过程和艺术创作之间的互动关系,揭示出这种关系在他们的个人生活、创作活动和作品中的作用和意义。以往的病迹学文学研究过多拘泥于精神医学的范畴对作家的疾病史作资料性的分析,实际上它更需带有文学批评的自觉,运用其独特的视角更积极地参与对作品的审美和对作家全方位的解读。     

《青龙潭》:三十年代中国农村的镜像写照

作为洪深代表作《农村三部曲》之一的《青龙潭》,由于极左思想的影响长久以来一直处于被贬抑的地位,不能和前两部相提并论。但实际上《青龙潭》深刻揭示了中国农村落后的根源,是三十年代中国农村的镜像写照。     

关于母系制与父权制

对母系制与父权制的解释,关系到我们对整个历史的解释以及对人类未来的期望。本文列举了对母系制与父权制的种种误读,并根据恩格斯的《家庭、私有制和国家的起源》的经典论述及理安·艾斯勒的《圣杯与剑》所记叙的克里特岛考古发现及我国考古发现,结合一些相关文学文本分析,对母系制与父权制这两个女性文学研究的元概念从社会结构与人与人的关系上进行了理论上的厘清与梳理,并分析了与此相关的“阳具中心主义”这个概念是对男性性能力的一种自大狂式的夸张和一个纯生物主义的虚假概念,从而认同了女性主义者的名言:“在中国,如果承认自己是女性主义者,也就同时意味着必须承认自己是男性主义者。”     

The failure of meta-analytic asymptotics for the seemingly efficient estimator of the common risk difference

We consider the case of a multicenter trial in which the center specific sample sizes are potentially small. Under homogeneity, the conventional procedure is to pool information using a weighted estimator where the weights used are inverse estimated center-specific variances. Whereas this procedure is efficient for conventional asymptotics (e. g. center-specific sample sizes become large, number of center fixed), it is commonly believed that the efficiency of this estimator holds true also for meta-analytic asymptotics (e.g. center-specific sample size bounded, potentially small, and number of centers large). In this contribution we demonstrate that this estimator fails to be efficient. In fact, it shows a persistent bias with increasing number of centers showing that it isnot meta-consistent. In addition, we show that the Cochran and Mantel-Haenszel weighted estimators are meta-consistent and, in more generality, provide conditions on the weights such that the associated weighted estimator is meta-consistent.     

Women's Work,Dirty Work: The Gynaecology Nurse as ‘Other’

This article seeks to explore the world of the gynaecology nurse. This world defines the gendered experience of nursing; that is, women in a women's job carrying out ‘women's work’. It is also a world that receives scant public recognition due to its association with the private domain of women's reproductive health. Many issues dealt with on a daily basis by gynaecology nurses are socially ‘difficult’: cancer, infertility, miscarriage and foetal abnormalities; or socially ‘distasteful’: termination of pregnancy, urinary incontinence, menstruation and sexually transmitted disease. The ‘tainted’ nature of gynaecology nursing gives it the social distinction of ‘dirty work’ but does not deter the gynaecology nurse from declaring her work as ‘special’, requiring distinctive knowledge and skills. Qualitative data collected from a group of gynaecology nurses in a North West National Health Service hospital displays how they actively celebrate their status as women carrying out ‘dirty work’. Through the use of ceremonial work that continually re‐affirms their ‘womanly’ qualities the gynaecology nurses establish themselves as ‘different’, as ‘special’, as the ‘other’.

养老计划倾向与商业养老保险需求——基于CFPS数据的实证研究

养老计划倾向作为一种行为因素，可以通过提高风险认知与管理意图，增加家庭对商业养老保险的需求。利用中国家庭追踪调查数据实证分析养老计划倾向与商业养老保险参保之间的关系，结果显示：（1）计算过养老费用的家庭会系统性地提高参保概率，计算过养老费用与否引致的参保概率差异占样本平均参保水平的40%以上；（2）养老费用计算结果也体现出逆向选择性，预计养老费用越高的家庭越倾向于参与商业养老保险；（3）养老计划倾向还会提高家庭对除商业养老保险外其他类型商业保险的需求，从而提高家庭整体商业保险参与水平。因此，提高家庭的养老计划倾向能有效促进商业养老保险市场，甚至整个商业保险市场的发展。     

Bayesian estimation in Kibble's bivariate gamma distribution

The authors describe Bayesian estimation for the parameters of the bivariate gamma distribution due to Kibble (1941). The density of this distribution can be written as a mixture, which allows for a simple data augmentation scheme. The authors propose a Markov chain Monte Carlo algorithm to facilitate estimation. They show that the resulting chain is geometrically ergodic, and thus a regenerative sampling procedure is applicable, which allows for estimation of the standard errors of the ergodic means. They develop Bayesian hypothesis testing procedures to test both the dependence hypothesis of the two variables and the hypothesis of equal means. They also propose a reversible jump Markov chain Monte Carlo algorithm to carry out the model selection problem. Finally, they use sets of real and simulated data to illustrate their methodology.
