Effects of relationship duration,cohabitation, and marriage on the frequency of intercourse in couples: Findings from German panel data

Research into the changes in the frequency of sexual intercourse is (with few exceptions) limited to cross-sectional analyses of marital duration. We investigate the frequency of intercourse while taking into account relationship duration as well as the duration of cohabitation and marriage, effects of parenthood, and relationship quality. For the analysis we apply fixed effects regression models using data from the German Family Panel (pairfam), a nationwide randomly sampled German panel survey. Our findings imply that the drop in sex frequency occurs early in the relationship, whereas neither cohabitation nor marriage affects the frequency of intercourse to a significant extent. Sex frequency is reduced during pregnancy and as long as the couple has small children, but becomes revived later on. Relationship quality is found to play a role as well. These results are contrary to the honeymoon effect found in earlier research, but indicate that in times of postponed marriage an analogous effect may be at work in the initial period of the relationship.     

Revisiting the gap between stylized and diary estimates of market work time

Previous studies find that workers of longer work weeks report more market hours in stylized measure than in time diary, while those of shorter work weeks report fewer hours. Using data from the American Time Use Survey (ATUS) 2003-2007, this paper attempts to explain this dilemma. I argue that market work time is composed of activity time, committed time, and constrained time. Thus, part of the difference found between the two estimates is due to the calculation of the diary estimate. I also argue that the wording of the stylized question is consequential. Some stylized questions (e.g., How many hours per week do you usually work?) might capture the mode, instead of the mean, of work time. Thus, when the distribution of work time is skewed, the mismatch between the two estimates is expected. A sequence-based identification for diary estimate and a non-parametric adjustment for stylized estimate are proposed and empirically examined. The result indicates that both methods significantly reduce the observed gap between the two estimates. I discuss the implications for future time use survey design in the concluding section.     

以实践思维方式重释历史和逻辑一致的方法

历史和逻辑一致的方法是从德国引入中国的，德国最先提出这个方法的是黑格尔，马克思恩格斯则有另一种表述。我国的著述却都沿用着黑格尔的表述，似乎根本不知道马克思恩格斯对这一方法从形式到内容都作了“颠倒过来”与“扬弃”之事。马克思恩格斯以实践为基础阐明了这一方法的内涵与关系，他们自觉地把这一方法纳入实践思维方式之内，并给出了掌握运用这一方法的三个方法论要求。

天人合意论——对天人和谐的一种大写意式阐释

通常,我们把人与自然万物的和谐哲学概称为"天人合一"。事实上,"天人合一"既不可能,也无必要,因而是一种不恰当的生硬表述。将传统和谐精神表述为"天人合意"再恰当不过。"天人合意"是一种大写意式的表述手法。"天人合意"的和谐哲学旨在说明,"天之意"理应是"人之意"的基础,"人之意"必须合乎"天之意"。必须循天之意。敬畏万有,和谐八方,方能达"天人合意"。"天人合意"表达了人们对万有存在之最佳存在状态和发展趋向的期盼。

Field of study variation throughout the college pipeline and its effect on the earnings gap: Differences between ethnic and immigrant groups in Israel

This study demonstrates the analytical leverage gained from considering the entire college pipeline—including the application, admission and graduation stages—in examining the economic position of various groups upon labor market entry. The findings, based on data from three elite universities in Israel, reveal that the process that shapes economic inequality between different ethnic and immigrant groups is not necessarily cumulative. Field of study stratification does not expand systematically from stage to stage and the position of groups on the field of study hierarchy at each stage is not entirely explained by academic preparation. Differential selection and attrition processes, as well as ambition and aspirations, also shape the position of ethnic groups in the earnings hierarchy and generate a non-cumulative pattern. These findings suggest that a cross-sectional assessment of field of study inequality at the graduation stage can generate misleading conclusions about group-based economic inequality among workers with a bachelor’s degree.

论明清小说读者与通俗小说传播的关系——以识语、凡例作为考察中心

明清时期是通俗小说创作及传播的高峰期,探究通俗小说的发展历程及其演变特征,小说读者是我们对此进行考察的一个重要视角。明清时期通俗小说插图非常盛行,附着于小说文本的插图在很大程度上是为适应读者的阅读需要而设置的。通俗小说的注释是为满足下层读者阅读服务的;而评点则是沟通小说作家、作品与读者之间的桥梁。至于续书的产生也与读者有着密切的关系;读者与小说续书的编刊目的和动机关系较为密切;续书编刊者在对原作人物进行修改、补充或续写时,常常会考虑到读者的阅读基础和阅读习惯;续书在情节结构的改造、安排诸方面,也有读者因素渗透的结果。
