The Role of Relational Uncertainty in Topic Avoidance among Couples with Depression

To address a key gap in theorizing and research, we consider relational uncertainty as an explanation for why individuals experiencing depressive symptoms may be reluctant to talk about sensitive issues. We report closed-ended online survey data from 126 romantic couples in which one or both partners had been professionally diagnosed with depression. Results indicated that relational uncertainty mediated the positive association between depressive symptoms and topic avoidance. Partner effects from men to women also emerged. These findings are valuable for identifying relational uncertainty as a mechanism that may explain people's unwillingness to discuss challenging topics when they are experiencing depressive symptoms.

The strategic value of data resources in emergent industries

In this paper we examine the strategic role of data resources in emergent industries. We contrast the resource-based view and the relational view theories to examine how data resources can help organizations create and capture value. We compare two organizations from two different industries to understand how different types of data resources can provide a competitive advantage. We also examine the role of strategic partnerships in capturing value created through the exploitation of data resources. We conclude that while data often serve as a required resource for entry into new markets, strategic partnerships play a critical role in capturing value created through the exploitation of data resources. The emergent partnership structures are remarkably similar across the two organizations. They target rapid market expansion through encapsulation of data resources within highly scalable web services and the use of standardized legal contracts. We also find that temporal decoupling between value creation and value capture can expose firms to the erosion of the competitive advantage gained through investment in data resources.     

现代大学生体育学习行为与特征的研究

为了指导大学生高效率地进行体育学习,采用问卷调查等方法,对现代大学生体育学习情况进行了调查与分析.结果表明：男女大学生体育学习行为既有共性,又有细徽差别;大学生获得体育知识的渠道呈多元化的特点,但教材被大学生普遍忽视,课前和课后均少阅读.课堂学习对象与方法单一,没有充分调动感官进行学习;自主性学习和合作学习积极性不高,学习效率低,课后练习的方式和方法需要改进.     

Equity,Equality, and Self-Interest in Marital Maintenance

This study investigated the extent to which generalized equity, a reciprocal exchange approach to maintenance (e.g., reward minus costs), and a self-interest approach (e.g., rewards only) were associated with marital satisfaction. An online survey was distributed to 547 heterosexual married individuals. Results supported equity predictions for six maintenance behaviors when using a categorical measure of equity, and for five of the maintenance behaviors when using a linear measure of equity. Counter to predictions, equity and sex did not interact on the use of maintenance. Finally, a combination of equity, reciprocal exchange, and self-interest predicted 57% of the variance in marital satisfaction.     

Relational aggressive behaviour: the contributions of status stress and status goals

Relational aggression is a destructive behaviour that increases during adolescence. In order to develop effective interventions aimed to combat relational aggression, there is an urgent need to study what motivates this behaviour. This study investigates the association between status stress, status goals, and relational aggressive behaviour in a sample of 345 adolescents from Norwegian secondary schools. Structural equation modelling (SEM) is used as the statistical tool. The results showed that status goals were associated with both self- and peer-reported relational aggression. Status stress contributed significantly to explaining variation in self-reported relational aggression but not in peer-reported relational aggression. The possibility that self- and peer report may partly identify different relational aggressive peers with different characteristics is discussed. No significant gender differences emerged in the associations studied.
