Is it pleasure or health from leisure that we benefit from most?:An analysis of well-being alternatives and implications for policy

International policy now constantly advocates a need for populations to engage in more physical activity to promote health and to reduce society’s health care costs. Such policy has developed guidelines on recommended levels and intensity of physical activity and implicitly equates health with well-being. It is assumed that individual, and hence social welfare will be enhanced if the activity guidelines are met. This paper challenges that claim and raises questions for public policy priorities. Using an instrumental variable analysis to value the well-being from active leisure, it is shown that the well-being experienced from active leisure that is not of a recommended intensity to generate health benefits, perhaps due to its social, recreational or fun purpose, has a higher value of well-being than active leisure that does meet the guidelines. This suggests rethinking the motivation and foundation of existing policy and perhaps a realignment of priorities towards activity that has a greater contribution to social welfare through its intrinsic fun and possibly social interaction

Early life social stress induced changes in depression and anxiety associated neural pathways which are correlated with impaired maternal care

Exposures to various types of early life stress can be robust predictors of the development of psychiatric disorders, including depression and anxiety. The objective of the current study was to investigate the roles of the translationally relevant targets of central vasopressin, oxytocin, ghrelin, orexin, glucocorticoid, and the brain-derived neurotrophic factor (BDNF) pathway in an early chronic social stress (ECSS) based rodent model of postpartum depression and anxiety. The present study reports novel changes in gene expression and extracellular signal related kinase (ERK) protein levels in the brains of ECSS exposed rat dams that display previously reported depressed maternal care and increased maternal anxiety. Decreases in oxytocin, orexin, and ERK proteins, increases in ghrelin receptor, glucocorticoid and mineralocorticoid receptor mRNA levels, and bidirectional changes in vasopressin underscore related work on the adverse long-term effects of early life stress on neural activity and plasticity, maternal behavior, responses to stress, and depression and anxiety-related behavior. The differences in gene and protein expression and robust correlations between expression and maternal care and anxiety support increased focus on these targets in animal and clinical studies of the adverse effects of early life stress, especially those focusing on depression and anxiety in mothers and the transgenerational effects of these disorders on offspring

The role of social contacts in the employment status of immigrants: A panel study of immigrants in Germany

Item does not contain fulltextSeveral studies in the migration literature have hypothesized that social contacts, in particular contacts with natives, are important for immigrant employment. Empirical work, however, has been inconclusive whether social contacts indeed have a causal effect. This study uses the German Socio-Economic Panel (1984—2004) to estimate the effect of social contacts of male and female immigrants on their employment position. Results show that contacts with family, friends and neighbours and being active as a volunteer have no significant effect on employment for both immigrant men and women. It is also found that having contacts with Germans increases the likelihood of male and female employment. The positive effect of having German contacts remains when social contacts are lagged, when host-country human capital is taken into account and also when unmeasured time-constant characteristics of immigrants are considered.28 p
