Nonstandard parental employment schedules and father involvement

This study assesses the impact of nonstandard employment schedules (shift work) on parenting among US fathers of young children in dual-earner couples. The outcomes examined include total caregiving, caregiving without the mother present, and the elements of father involvement proposed by Pleck: positive engagement, warmth, and control. Models with latent variables and with lagged dependent variables are estimated using three waves of nationally representative data from the Early Child Longitudinal Study – Birth Cohort. The results indicate that employment scheduling mainly shapes the context in which involvement takes place. Compared to dual-earner couples who are each employed during the day, fathers in couples in which at least one parent has a nonstandard schedule tend to care for their children more in the mother's absence. To a more limited extent, they also do more caregiving overall. These effects are most conclusively found when the father works during the day and the mother works during the evening, when the mother works during the day but the father works a night, split, rotating, or other shift, and when both parents have nonstandard schedules. Parental work schedules, however, have little impact on father involvement aside from care.     

空气中多种醛酮液相色谱法侧定的研究

本文研究了空气中多种醛酮的测定。目前国内仅对空气中甲醛的测定研究较多,国外报导的方法需用萃取、浓缩等一系列前处理过程,方法麻烦,易引入杂质造成污染。本文报导的方法系采用2.4—二硝基苯肼的甲醇强酸溶液吸收空气中醛酮直接注入液相色谱仪中进行分离测定。研究表明:本法分离效果好,重复性好,方法简便,速度快,测定的精密度和准确度符合微量分析误差的要求。     

Early stopping in seamless phase I/II clinical trials

In recent years, seamless phase I/II clinical trials have drawn much attention, as they consider both toxicity and efficacy endpoints in finding an optimal dose (OD). Engaging an appropriate number of patients in a trial is a challenging task. This paper attempts a dynamic stopping rule to save resources in phase I/II trials. That is, the stopping rule aims to save patients from unnecessary toxic or subtherapeutic doses. We allow a trial to stop early when widths of the confidence intervals for the dose-response parameters become narrower or when the sample size is equal to a predefined size, whichever comes first. The simulation study of dose-response scenarios in various settings demonstrates that the proposed stopping rule can engage an appropriate number of patients. Therefore, we suggest its use in clinical trials.     

A procedure for testing the equality of k dependent correlation coefficients

A procedure is proposed for testing the equality of k dependent correlation coefficients. The procedure is simulated utilizing Monte Carlo techniques; and, a method for post hoc probing is also suggested.     

Adaptive designs for single‐arm phase II trials in oncology

Clinical phase II trials in oncology are conducted to determine whether the activity of a new anticancer treatment is promising enough to merit further investigation. Two‐stage designs are commonly used for this situation to allow for early termination. Designs proposed in the literature so far have the common drawback that the sample sizes for the two stages have to be specified in the protocol and have to be adhered to strictly during the course of the trial. As a consequence, designs that allow a higher extent of flexibility are desirable. In this article, we propose a new adaptive method that allows an arbitrary modification of the sample size of the second stage using the results of the interim analysis or external information while controlling the type I error rate. If the sample size is not changed during the trial, the proposed design shows very similar characteristics to the optimal two‐stage design proposed by Chang et al. (Biometrics 1987; 43:865–874). However, the new design allows the use of mid‐course information for the planning of the second stage, thus meeting practical requirements when performing clinical phase II trials in oncology.

网络怨恨的价值位移——基于舍勒现象学的分析

当前网络表达中到处弥漫的怨恨情绪,使技术理性的价值产生位移或曰颠覆,正价值如正义、公平、为承认而斗争等,在怨恨的情绪及其网络表达中导向负价值:网络暴政、人的主体性的消解,使人陷入"单向度的人"的危险。当下网络表达的无序和失序,正是怨恨的现象学呈现。因而,透过现象学观察的怨恨及其网络表达,或许可为我们反思批判当下和建构新的网络伦理提供一个新的思路。     

从革命文化到红色文化：一项概念史的研究与分析

方兴未艾的中国红色文化研究,首先需要面对的是从革命文化到红色文化的概念转换,这一概念转换以及与当下社会语境的关联,是当前文化研究中特别值得注意的学术现象,但学界对之探究甚少。这里尝试构建适应红色文化研究的概念逻辑,采用概念史的研究方法,对革命文化向红色文化的概念转换加以研究。革命文化与红色文化都是以革命为主导理念的文化形态;但红色文化同时还是当前特别值得关注的文化现象。这一概念转换是在重新认识革命与革命文化的时代语境下发生的,红色教育、红色旅游与红色文化产业开发,是红色文化兴起的主要契机,凸显了当前社会对革命文化的资源属性的高度重视,体现了后革命时代境遇下革命话语的转型。     

论辛亥革命前后西北诸马军阀的角色转换

辛亥革命期间，甘宁青诸马军阀从静观其变到出师勤王，最后临阵倒戈、回兵参与光复运动，就角色而言，完成了从传统社会卫道士而至掘墓人的转换；就性质而论，自身开始并逐步完成了由封建时代拥兵自重的地方实力派向民国时代资产阶级新军阀的过渡。本文旨在探讨辛亥革命对西北诸马军阀集团新旧交替的转换催化作用。     

"城市化"发展模式的选择与农村剩余劳动力转移

"三农"问题是我国的重中之重,解决"三农"的突破口在农村剩余劳动力的转移,而"城市化"则是转移的最佳途径.我国建国以来一直采用城乡分隔的管理体制,城市化远远滞后于工业化.在城市化不同的发展模式选择上,有以大中城市发展为重心和以发展小城镇为重心两种主要观点.不同的城市化发展模式对农村剩余劳动力转移影响不同.根据我国的国情,我国的城市化模式应该是既能发挥城市的集聚功能,又能很好地实现农村剩余劳动力的转移.由此,我国应该以发展大中城市为主,小城镇建设为辅助.在大城市转移剩余劳动力有限的情况下,小城镇可以发展以为农服务的产业来实现农村剩余劳动力的非农化转移.
