Correlates of physical activity participation in community-dwelling older adults

The authors examined factors related to participation in walking, gardening or yard work, and sports or exercise in 686 community-dwelling adults 60-95 years of age from Wave IV of the population-based Americans' Changing Lives Study. Logistic regression revealed that male gender, being married, and better functional health were associated with greater likelihood of participating in gardening or yard work (p < .05). Male gender, better functional health, and lower body-mass index were independently associated with greater likelihood of walking (p < .05). Increasing age, male gender, higher education, and better functional health were associated with greater likelihood of participating in sports or exercise (p < .05). Subsequent analyses yielded an interaction of functional health by gender in sport or exercise participation (p = .06), suggesting a greater association between functional health and participation in men. Gender and functional health appear to be particularly important for physical activity participation, which may be useful in guiding future research. Attention to different subgroups may be needed to promote participation in specific activities.     

How to be a Marriage Therapist Without Knowing Practically Anything

Therapists in training as marriage and family therapists often do not learn techniques for bringing about change. They also do not learn ways to conceal from colleagues and from clients the fact that they do not know how to solve the presenting problems of couples in distress. Both general and specific techniques are reviewed for concealing ignorance as well as ways to make correct excuses for failure. The presentation is designed for therapists who find themselves not knowing what to do with a couple in a particular case and for therapists who do not know what to do with any case .     

Disparity,Shortfall, and Twice-Endogenous HARA Utility

We derive a mapping between the shortfall-minimizing portfolio selection based on higher-order entropy measures and expected utility theory. We show that the family of HARA utility functions has a minimum-divergence, shortfall-based representation. This facilitates an interpretation in which the risk aversion parameters and the type of risk aversion arise endogenously. We provide a numerical example illustrating this interpretation.     

Media Exposure, Aggression and Prosocial Behavior During Early Childhood: A Longitudinal Study

Preschool children (N = 78) enrolled in multi‐informant, multi‐method longitudinal study were participants in a study designed to investigate the role of media exposure (i.e., violent and educational) on concurrent and future aggressive and prosocial behavior. Specifically, the amount of media exposure and the nature of the content was used to predict concurrent and future physical, verbal and relational aggression as well as prosocial behavior for girls and boys. This two‐year longitudinal study found that media exposure predicted various subtypes of aggression and prosocial behavior. These findings are qualified by the gender of the focal child. That is, parental reports of media exposure were associated with relational aggression for girls and physical aggression for boys at school. Ways in which these findings extend our understanding of the role of media during early childhood are discussed.

From Apathy to Vigilance: Young Adolescents’ Reactions to the Unite the Right Rally in Charlottesville

The present study examined middle school students’ responses to the 2017 Unite the Right rally in Charlottesville, Virginia. Using a consensual qualitative research approach, we analyzed interviews from 73 local, seventh‐grade students (58% female; 55% students of color) to explore the range of students’ emotional responses and cognitive engagement with the events. The resulting six profiles document heterogeneity in meaning‐making and personal impacts across youth. Individual and social factors including race and ethnic identity varied across profiles. Many students of color expressed fear and vigilance toward racial violence while many White students expressed sadness and sympathy. We discuss the role of developmental factors in students’ reactions as well as implications for supporting early adolescents in the wake of bias‐motivated violence.     

Family Instability and Exposure to Violence in the Early Life Course

Family instability has been linked with a host of outcomes across the early life course. This study extends this literature by connecting instability with violence in the community by examining the associations among family structure, family structure change, and secondary exposure to violence during adolescence across diverse segments of the population. Using longitudinal data from the Project on Human Development in Chicago Neighborhoods study, we found that living with a single parent and experiencing family structure changes were associated with secondary exposure to violence. Multiple group models suggest that partner change translated into more exposure for boys than girls. Findings also suggest that family instability may lead to more secondary exposure to violence for African American youth.
