Health Outcomes and Volunteering: The Moderating Role of Religiosity

In this paper, we examine whether and what extent public and private forms of religiosity act as moderators of the volunteering and well-being relationship in mid- to later-life. We use data from the second wave of the National Survey of Midlife Development in the United States (n = 1,805). We analyzed the relationships between volunteering and indicators of well-being (self-rated physical and mental health), and tested the moderating effects of public and private religiosity on the volunteering and well-being relationship. Our findings suggest that salubrious effects of volunteering on the self-perceived physical and mental health of middle- aged and older- aged adults varied by their participation in different forms of religiosity. In particular, volunteers who engaged in more public forms of religiosity reported significantly better physical and mental health than non-volunteers who engaged in these forms of religiosity. In other words, individuals who were actively engaged public forms of religious practices and who volunteered, maximized the associated health benefits.     

Seeing Red (and Blue): Effects of Electoral College Depictions on Political Group Perception

Colored maps depicting electoral results may exacerbate perceptions of polarization, rather than merely reflecting them. Participants viewed maps of state-by-state Presidential election results that were either Electoral (red/Republican or blue/Democrat) or Proportional (purples that proportionally reflected each group's support). Half of the maps also displayed state-level numeric electoral results. Participants viewing Electoral maps perceived the nation as more politically divided, stereotyped the political beliefs of residents of various states more, and saw people holding views in the political minority as less agentic and less likely to vote. These differences occurred even in the presence of numeric data. Implications of these findings for intergroup perception in several domains are discussed, including the impact of electoral depictions on political campaigns and elections .     

The Relationship Between Narcissistic Exploitativeness,Dispositional Empathy,and Emotion Recognition Abilities

The present research explores the link between the personality trait exploitativeness, a component of narcissism, and emotion recognition abilities. Prior research on this topic has produced inconsistent findings. We attempt to resolve these inconsistencies by testing the hypothesis that narcissistic exploitativeness, in particular, should be associated with emotion-reading abilities because it specifically taps into the motivation to manipulate others. Across two studies we find that narcissistic exploitativeness is indeed associated with increased emotion recognition, but in some cases the confounding effects of mood need to be considered (Study 1). Importantly, effect sizes of narcissistic exploitativeness were similar in magnitude to two different measures of dispositional empathy, which is an established correlate of emotion recognition. These studies suggest that emotional recognition abilities are associated with desirable and undesirable traits.

A Century of Nonprofit Studies: Scaling the Knowledge of the Field

This empirical study examines knowledge production between 1925 and 2015 in nonprofit and philanthropic studies from quantitative and thematic perspectives. Quantitative results suggest that scholars in this field have been actively generating a considerable amount of literature and a solid intellectual base for developing this field toward a new discipline. Thematic analyses suggest that knowledge production in this field is also growing in cohesion—several main themes have been formed and actively advanced since 1980s, and the study of volunteering can be identified as a unique core theme of this field. The lack of geographic and cultural diversity is a critical challenge for advancing nonprofit studies. New paradigms are needed for developing this research field and mitigating the tension between academia and practice. Methodological and pedagogical implications, limitations, and future studies are discussed.     

Bayesian regularisation in structured additive regression: a unifying perspective on shrinkage, smoothing and predictor selection

This paper surveys various shrinkage, smoothing and selection priors from a unifying perspective and shows how to combine them for Bayesian regularisation in the general class of structured additive regression models. As a common feature, all regularisation priors are conditionally Gaussian, given further parameters regularising model complexity. Hyperpriors for these parameters encourage shrinkage, smoothness or selection. It is shown that these regularisation (log-) priors can be interpreted as Bayesian analogues of several well-known frequentist penalty terms. Inference can be carried out with unified and computationally efficient MCMC schemes, estimating regularised regression coefficients and basis function coefficients simultaneously with complexity parameters and measuring uncertainty via corresponding marginal posteriors. For variable and function selection we discuss several variants of spike and slab priors which can also be cast into the framework of conditionally Gaussian priors. The performance of the Bayesian regularisation approaches is demonstrated in a hazard regression model and a high-dimensional geoadditive regression model.
