Relationship quality of gay men in closed or open relationships

This study compared gay men in monogamous ("closed") relationships (n = 98) and gay men in nonmonogamous ("open") relationships (n = 34). Partners in open relationships were living together significantly longer than partners in closed relationships. Partners in the two types of relationships did not differ in Psychological Adjustment. Controlling for length of time living together, partners in closed relationships reported higher Affiliation/Dependency, more Favorable Attitudes toward the Relationship, and lower Tension than partners in open relationships. Global relationship quality for both types of couples was related to many Attractions, many Barriers, and few Alternatives to the relationship; few beliefs regarding both Disagreement is Destructive and Partners Cannot Change; high Dyadic Attachment; high Shared Decision Making; and low Psychological Maladjustment. Partners in both types of relationships were more similar to each other than different from each other, especially on the variables of Relationship Quality, a belief in Partner Changeability, and Dyadic Attachment.     

The FastHCS algorithm for robust PCA

Principal component analysis (PCA) is widely used to analyze high-dimensional data, but it is very sensitive to outliers. Robust PCA methods seek fits that are unaffected by the outliers and can therefore be trusted to reveal them. FastHCS (high-dimensional congruent subsets) is a robust PCA algorithm suitable for high-dimensional applications, including cases where the number of variables exceeds the number of observations. After detailing the FastHCS algorithm, we carry out an extensive simulation study and three real data applications, the results of which show that FastHCS is systematically more robust to outliers than state-of-the-art methods.     

Impact of an Overt Response System on Staff Performance and Maintenance of Computer-Based Instruction

Interactive Computer Based Instruction (CBI) systems involve teaching strategies to facilitate greater response opportunities during training in an effort to improve learner performance. The current study investigated the effect of online staff training videos with and without overt response requirements on posttest and maintenance test scores across six block-randomized instructional modules for four employees of a university located in the southeastern region of the United States. The overt response consisted of multiple-choice questions administered throughout select teaching modules using an alternating treatment design. Findings suggest that learning occurred as a result of the CBI training; however, the effectiveness of the overt response system varied across individuals, with no discernible differentiation between learning gains associated with response requirements. Other areas of research for expanding the efficacy of CBI and overt response systems are highlighted.     

The Mental Health Advantage of Immigrant‐Background Youth: The Role of Family Factors

Children of immigrant background, despite problems with acculturation, poverty, and discrimination, have better mental health than children of native parents. We asked whether this is a result of immigrant families' characteristics such as family structure and relations. Using a new comparative study on the integration of immigrant‐background youth conducted in England, Germany, the Netherlands, and Sweden (N = 18,716), particularly strong associations with mental health (internalizing and externalizing problems) were found for family structure, family cohesion, and parental warmth. Overall, half of the advantage in internalizing and externalizing problems among immigrant‐background youth could be accounted for by our measures of family structure and family relations, with family cohesion being particularly important.     

Policy Diffusion and Policy Transfer in Comparative Welfare State Research

For many years, comparative welfare state research has followed a ‘methodological nationalism’ in the sense that countries were treated as independent units. Yet the recent ‘spatial turn’ in comparative politics has also influenced welfare state research. For some years now, the field has been witnessing a growing interest in questions about interdependencies and policy diffusion between countries. In this article, we provide a structured overview of the state of the art in the policy diffusion and transfer literature that deals specifically with social policy. We present and critically evaluate existing theoretical concepts and quantitative and qualitative methodological approaches that enable the analysis of interdependencies between countries. Moreover, we summarize the empirical findings of quantitative and qualitative studies on the diffusion and transfer of social policy, from some pioneering studies to the latest findings. Against this background we point out what we believe to be promising avenues for future research. We focus on five areas: theoretical work on the mechanisms underlying diffusion and transfer; methodological approaches; the impact of domestic institutions and policy characteristics on social policy diffusion and transfer; programme‐specific dynamics; and the systematic combination of horizontal and vertical interdependencies.     

Path-related empirical research on M&A-outcome: review and research agenda

This article attempts to reflect the current state and progress of contemporary research on financial and non-financial M&A outcome. Based on a review of 183 empirical M&A studies an integrative framework is developed, in which impact factors are classified into four major dimensions to explore the impact on M&A outcome: antecedents, transaction content characteristics, transaction process characteristics, and the transaction itself. The review reveals that M&A research is dominated by studies focusing on state variables at the expense of path-related variables. The review also shows that, to date, neither state-related research nor path-related research on financial and non-financial M&A outcome categories have reached maturity. Although there is still room for clarifying the impact of various state-related variables, the most valuable new insights are expected to emerge from researching path-related variables. Building on these insights, an extensive future research agenda is presented, which focuses on path-related research questions and methodological issues.     

Personality preferences in laboratory economics experiments

Student volunteers at the U.S. Naval Academy (USNA) participated in one of the following one-shot games: a dictator game, an ultimatum game, a trust game, or a prisoner's dilemma game. We find limited support for the importance of personality type for explaining subjects’ decisions. With controls for personality preferences, we find little evidence of behavioral differences between males and females. Furthermore, we conclude that seniority breeds feelings of entitlement—seniors at USNA generally exhibited the least cooperative or other-regarding behavior.
