Statutory leave entitlements across developed countries: Why US workers lose out on work–family balance

Using a composite index of legal provisions for annual and family leave in western Europe, the United States, Canada, Australia, Japan and the Republic of Korea, the authors rank legislative support for this aspect of work–family balance. The United States ranks last: its employers are not required to grant annual leave and employees can take no more than 12 weeks' family leave per year. The United States' comparatively low labour standards, the authors argue, may be due to the dominance of a market‐based conception of employment and the assumption of equal employer–employee bargaining power, neither of which is fully shared by the other industrialized democracies.     

Why do the poor oppose income redistribution? An empirical test on the impacts of nationalism and fatalism

We study the poor’s psychological motivations to oppose income redistribution, relying on social identity and system justification theories. We find that national identification reduces differences between the poor and the rich in terms of attitudes toward income redistribution and self-esteem, by discouraging the poor from supporting redistribution but encouraging them to acquire greater self-esteem. Next, fatalism reduces and increases differences between the poor and the rich in terms of attitudes toward income redistribution and self-esteem, respectively. Yet, a closer look reveals that the responding patterns of the poor and the rich to fatalism are consistent only with the mechanism behind the prediction that concerns self-esteem. That is, fatalism increases support for income redistribution in both groups, whereas it reduces self-esteem only among the poor.     

Influence of alliance portfolio diversity on innovation performance: the role of internal capabilities of value creation

In this study, we suggest a new perspective on the linkage between alliance portfolio diversity and innovation performance based on a contingency approach. Using a longitudinal data set on alliance portfolios and patents of 182 firms in the U.S. manufacturing industries, we examined that alliance portfolio diversity has a U-shaped relationship with firm-level innovation. Internal value creation capabilities in terms of routine and ability are found to moderate the relationship between alliance portfolio diversity and innovation performance: organizational search routine strengthens the relationship of alliance portfolio diversity and innovation performance while technological capabilities weaken and flip the relationship.

     

茶树TRAP反应体系的建立及正交设计优化

TRAP标记技术因操作简单、重复性好、效率高等特点得到广泛应用,但该技术在茶树中的研究报道较少,且茶树TRAP-PCR体系优化尚未见报道.笔者采用正交设计的方法,对茶树TRAP-PCR反应中Mg2+、Taq酶、dNTP、固定引物、随机引物5个因素进行了优化研究,建立了茶树TRAP-PCR最佳反应体系.该20μL反应体系含有2μL 10×PCR Buffer (Mg2+ free),50 ng模板DNA,1.75 mmo/L Mg2+,0.50 U Taq酶,0.20 mmol/L dNTP,0.20 mmol/L随机引物和0.20 mmol/L固定引物.根据优化结果,利用最佳反应体系,选用16个茶树品种对TRAP标记多态性进行了初步研究.     

从分类研究到类型研究——兼论中国电视剧类型研究的意义与方法

当今中国电视剧的创作日益向类型化方向发展,电视剧研究方法与研究模式也需要随之而发展。然而电视剧类型研究的理论来源及研究范式应该是研究中首先要确定的前提。本文主要探讨与电视剧类型相关的几个问题：电视剧类型研究的理论起点,电视剧类型的划分原则及电视剧类型研究的具体方法。力图为今后的电视剧研究提供参照。

由史俗到经述：彝族毕摩经籍中的“狸猫换太子”故事

彝族毕摩经籍中出现了关于宋仁宗的“狸猫换太子”故事，在历史记载、说书演义、叙事模式、社会语境、仪式过渡的共同作用下，由毕摩撰写完成了“仁宗的故事”。但是，该故事又由自己的方式来讲述，其深层次结构与很多故事类型和原型仪式有相似之处。
