The multifaceted nature of prosocial behavior in children: Links with attachment theory and research

Prosocial behavior involves attempting to improve others’ welfare and plays a central role in cooperative social relationships. Among the manifold processes that contribute to prosocial development is the quality of children's attachment to their caregivers. Often, researchers have investigated the link between secure attachment and broad indices of prosociality. Recent theory and research, however, suggest that children's prosocial behavior is multifaceted, with distinct correlates and developmental trajectories characterizing specific prosocial behaviors. We offer a theoretical model of the role of parent–child attachment in the development of prosocial behavior, first broadly, and then with regard to comforting, sharing, and helping, specifically. Further, we review the empirical work on this topic from infancy through adolescence. Overall, evidence supports an association between secure attachment and prosociality, broadly defined, but results vary across comforting, sharing, and helping. We discuss potential explanations for the findings and outline directions for future research examining the role of attachment in shaping the diversity of prosocial behaviors across development.     

Cointegration: Bayesian Significance Test

To estimate causal relationships, time series econometricians must be aware of spurious correlation, a problem first mentioned by Yule (1926 Yule , G. U. ( 1926 ). Why we do sometimes get nonsense-correlations between time-series? A study in sampling and the nature of time-series (with discussion) . J. Roy. Statist. Soc. 89 : 1 – 64 .[Crossref] , [Google Scholar]). To deal with this problem, one can work either with differenced series or multivariate models: VAR (VEC or VECM) models. These models usually include at least one cointegration relation. Although the Bayesian literature on VAR/VEC is quite advanced, Bauwens et al. (1999 Bauwens , L. , Lubrano , M. , Richard , J.-F. ( 1999 ). Bayesian Inference in Dynamic Econometric Models . Oxford : Oxford University Press . [Google Scholar]) highlighted that “the topic of selecting the cointegrating rank has not yet given very useful and convincing results”.

The present article applies the Full Bayesian Significance Test (FBST), especially designed to deal with sharp hypotheses, to cointegration rank selection tests in VECM time series models. It shows the FBST implementation using both simulated and available (in the literature) data sets. As illustration, standard non informative priors are used.     

Discrete Effects of Religiosity and Spirituality on Gay Identity and Self-Esteem

Previous research has indicated that although spirituality may bolster development of a positive gay identity, religiosity may prove detrimental. Because the majority of this research confounds these constructs, there is little evidence as to the discrete roles religiosity and spirituality may play in LGB identity development. The present study endeavored to tease apart the unique effects of religion and spirituality on positive and negative gay identity and self-esteem. A sample of 376 self-identified sexual minority adults were given measures of religiosity, spirituality, LGB identity, and self-esteem. Models were built to evaluate the effects of religiosity (independent of spirituality) and spirituality (independent of religiosity), understanding that the constructs are greatly overlapped, on identity and self-esteem. Results included a positive association between spirituality and identity affirmation, identity superiority, and self-esteem. Religiosity was negatively associated with identity affirmation and self-esteem and positively associated with internalized homonegativity and heteronormativity. Limitations and implications are discussed.     

Reluctant rural regionalists

Recently, scholars have begun to explore questions of regionalism and regionalization in rural contexts. Regionalism is often understood and presented as a pragmatic solution to intractable problems of fragmentation, inefficiency, accountability, spillover and neglect in the face of economic restructuring and other external threats. These arguments have long been deployed in the top-down restructuring of rural public administration; for example, the amalgamation of service districts to keep schools, hospitals and other facilities open in the face of declining population. At the same time, regionalization may be understood as a ‘means’ or process of becoming through the formation of new and shared regional identities, “structures of expectation” and institutions. Between 1996 and 2004 the number of municipalities in the Canadian Province of Ontario was reduced by more than 40 percent from 815 to 445. Evidence suggests that many of these amalgamations were undertaken reluctantly. In this paper we examine the issue of regionalism from the perspective of one rural municipality—the former silver mining centre of Cobalt, Ontario—that has resisted amalgamation. We argue that its resistance to amalgamation is a consequence of the conflictual social relationships that have been inscribed into the landscape over the past century. Using documentary and archival materials, supplemented by contemporary survey and ethnographic data, we trace how successive generations of miners, mine-owners, government officials, politicians and residents have constructed Cobalt as a distinct place. We show that this oppositional identity belies the extent to which the town and its citizens are embedded in regional housing, labour and consumer markets.     

Social Psychological and Structural Influences on Vegetarian Beliefs

Abstract This study examines the link between social structural variables (gender, race, education, age, rural childhood), individual social psychology (altruism, self-interest, traditionality, and openness to change), and beliefs about the benefits of vegetarianism (for health, the environment, animals, and world hunger) and self-reported vegetarianism. Data from a random sample of 420 adult U.S. residents showed that 5.2 percent considered themselves vegetarian. The strongest predictor of vegetarianism as a dietary choice was the belief that vegetarianism is beneficial to the environment. None of the social structural variables had a direct influence on vegetarianism as a dietary choice. Of the four values studied, only altruism and traditional values influenced beliefs about the benefits of vegetarianism. Altruistic values increased, and traditional values decreased, beliefs that vegetarianism is beneficial to health, the environment, farm animals, and world hunger. Blacks were more likely than Whites to adhere to the beliefs that vegetarianism helps prevent cruelty to farm animals, is beneficial to personal health, and is beneficial to the environment. The race differences in beliefs persisted even with controls for values.
