Patterns of Volunteer Activity in Professional Associations and Societies

Professional and occupational societies rely on volunteers for leadership, expertise, member recruitment, fundraising, legislative activity, and many other activities. Yet, volunteerism in the professions has received very little analytic attention. This study uses a large, international dataset produced by the American Society of Association Executives to examine patterns of volunteer activity in 23 professional associations and societies. A comparative analysis allows us to test widespread theories on the factors that predict volunteer activity in the particular context of professional life, where the motivations to volunteer may vary. Our findings suggest that some patterns of professional volunteer activity mirror what we can expect in a non-professional context (i.e., church or community volunteering), while other patterns are distinct. Our findings have particular relevance in understanding that a professional??s demographic characteristics and voluntary preferences are context-specific and must be accounted for in volunteer recruitment efforts.     

Exploring the relationship between parents’ and children’s housework time in Spain

Intergenerational transmission has been successfully employed in economic research to explain the persistence of certain economic behaviors across generations. This paper evaluates the relevance of this transmission process in the formation of gender roles during childhood. In particular, we analyze the relationship between parents?? and children??s housework allocation patterns. We propose a simple theoretical model that predicts that parents with a strong adherence to gender to traditional gender norms??as proxied by their division of household labor??are more likely to allocate housework to children in a way that reflects stereotypes of men??s and women??s domestic tasks. The empirical application is carried out with data from the 2002?C2003 Spanish Time Use Survey. The sample restricts to two-parent households with at least one child aged 10?C17?years. We find a significant positive correlation between a more egalitarian parents?? allocation of housework and a less asymmetrical distribution of domestic chores between sons and daughters.     

Infant Preference for Natural Texture Statistics is Modulated by Contrast Polarity

Adult observers are sensitive to statistical regularities present in natural images. Developmentally, research has shown that children do not show sensitivity to these natural regularities until approximately 8–10 years of age. This finding is surprising given that even infants gradually encode a range of high‐level statistical regularities of their visual environment in the first year of life, We suggest that infants may in fact exhibit sensitivity to natural image statistics under circumstances where images of complex, natural textures, such as a photograph of rocks, are used as experimental stimuli and natural appearance is substantially manipulated. We tested this hypothesis by examining how infants' visual preference for real versus computer‐generated synthetic textures was modulated by contrast negation, which produces an image similar to a photographic negative. We observed that older infants' (9‐months of age) preferential looking behavior in this task was affected by contrast polarity, suggesting that the infant visual system is sensitive to deviations from natural texture appearance, including (1) discrepancies in appearance that differentiate natural and synthetic textures from one another and (2) the disruption of contrast polarity following negation. We discuss our results in the context of adult texture processing and the “perceptual narrowing” of visual recognition during the first year of life.     

Speaking Out: Youth Led Research as a Methodology Used with Homeless Youth

Participatory action research is well documented with marginalized groups, but less is known about participatory action research with homeless youth. The use of youth led research as a methodology was examined among a population of homeless youth. Peer researchers (n = 10) reported on their experience utilizing youth led research methodology. Results indicate that youth led research is a promising methodology for use among homeless youth. Participants reported that the approach positively impacted the quality and quantity of data that could be collected from participants. Further, peer researchers reported individual benefits of feeling that participating in the project mattered, that people listened to them and that they had a voice.     

Friends and family: regulation and relationships on the locked ward

This ethnographic project explored the lives of women with learning disabilities on three locked wards. Aspects of these women’s lives were regulated by the service; in particular, relationships with family outside the unit, and peer relationships inside the unit. The women in this study valued these relationships, but they were treated with ambivalence by the service. Success in future community integration and accessing community resources can be dependent on the nature and quality of relationships with others, and therefore services should acknowledge that service-users need to forge relationships of their own choosing.     

Justice Sensitivity in Childhood and Adolescence

Individuals differ in their sensitivity toward injustice. Justice‐sensitive persons perceive injustice more frequently and show stronger responses to it. Justice sensitivity has been studied predominantly in adults; little is known about its development in childhood and adolescence and its connection to prosocial behavior and emotional and behavioral problems. This study evaluates a version of the justice sensitivity inventory for children and adolescents (JSI‐CA5) in 1472 9‐ to 17‐year olds. Items and scales showed good psychometric properties and correlations with prosocial behavior and conduct problems similar to findings in adults, supporting the reliability and validity of the scale. We found individual differences in justice sensitivity as a function of age and gender. Furthermore, justice sensitivity predicted emotional and behavioral problems in children and adolescents over a 1‐ to 2‐year period. Justice sensitivity perspectives can therefore be considered as risk and/or protective factors for mental health in childhood and adolescence.     

Risk Perception: Reflections on 40 Years of Research

Numerous studies and practical experiences with risk have demonstrated the importance of risk perceptions for people's behavior. In this narrative review, we describe and reflect upon some of the lines of research that we feel have been important in helping us understand the factors and processes that shape people's risk perceptions. In our review, we propose that much of the research on risk perceptions to date can be grouped according to three dominant perspectives and, thus, approaches to study design; they are: the characteristics of hazards, the characteristics of risk perceivers, and the application of heuristics to inform risk judgments. In making these distinctions, we also highlight what we see as outstanding challenges for researchers and practitioners. We also highlight a few new research questions that we feel warrant attention.

Substance use and vulnerability to sexual and physical aggression: a longitudinal study of young adults

Using data from 2,170 individuals who participated in Waves 8 (age 23) and 9 (age 29) of a multiyear panel study, this study examined whether alcohol and marijuana use in young adulthood increase one's risk for experiencing subsequent sexual or physical assault victimization, whether victims' own violent behavior or involvement in the sale of drugs explain any effects of substance use on victimization, and whether these associations differ by gender. Controlling for prior victimization, we found that marijuana use, but not alcohol use, predicted women's and men's subsequent sexual victimization and men's subsequent physical assault victimization, and that heavy alcohol use, but not marijuana use, predicted women's subsequent physical assault victimization. Whereas the links from marijuana use to victimization were explained by users' own violent behavior, the link from alcohol use to women's physical assault victimization was not.
