Religiosity is associated with greater size, kin density, and geographic dispersal of women's social networks in Bangladesh

Human social relationships, often grounded in kinship, are being fundamentally altered by globalization as integration into geographically distant markets disrupts traditional kin based social networks. Religion plays a significant role in regulating social networks and may both stabilize extant networks as well as create new ones in ways that are under-recognized during the process of market integration. Here we use a detailed survey assessing the social networks of women in rural Bangladesh to examine whether religiosity preserves bonds among kin or broadens social networks to include fellow practitioners, thereby replacing genetic kin with unrelated co-religionists. Results show that the social networks of more religious women are larger and contain more kin but not more non-kin. More religious women's networks are also more geographically diffuse and differ from those of less religious women by providing more emotional support, but not helping more with childcare or offering more financial assistance. Overall, these results suggest that in some areas experiencing rapid social, economic, and demographic change, religion, in certain contexts, may not serve to broaden social networks to include non-kin, but may rather help to strengthen ties between relatives and promote family cohesion

Patterns of Paternal Investment Predict Cross-Cultural Variation in Jealous Response

Long-lasting, romantic partnerships are a universal feature of human societies; but almost as ubiquitous is the risk of instability that comes when one partner strays. Jealous response to the threat of infidelity is a well-studied phenomenon, but most empirical work on the topic has focused on a proposed sex difference in the type of jealousy (sexual or emotional) men and women find most upsetting, rather than on how jealous response varies1,2. This stems in part from the predominance of studies using student samples from industrialized populations, which represent a relatively homogenous group in terms of age, life history stage, and social norms3,4. To better understand variation in partner jealousy, we conducted a two-part study in 11 populations (1,048 individuals), including eight small-scale societies, which examines how both sex and culture affect perceptions of infidelity. We show that, in spite of a robust sex difference, variation in jealous response is impacted more by the culture a respondent belongs to than by their sex. We further identify paternal investment and frequency of extramarital sex as two key predictors of cultural variation. Partner jealousy thus appears to be a facultative response, in part reflective of the variable risks and costs of men’s investment across societies

High‐altitude adaptations mitigate risk for hypertension and diabetes‐associated anemia

BACKGROUND: Human populations native to high altitude exhibit numerous genetic adaptations to hypobaric hypoxia. Among Tibetan plateau peoples, these include increased vasodilation and uncoupling of erythropoiesis from hypoxia. OBJECTIVE/METHODS: We tested the hypothesis that these high‐altitude adaptations reduce risk for hypertension and diabetes‐associated anemia among the Mosuo, a Tibetan‐descended population in the mountains of Southwest China that is experiencing rapid economic change and increased chronic disease risk. RESULTS: Hypertension was substantially less common among Mosuo than low‐altitude Han populations, and models fit to the Han predicted higher probability of hypertension than models fit to the Mosuo. Diabetes was positively associated with anemia among the Han, but not the Mosuo. CONCLUSION: The Mosuo have lower risk for hypertension and diabetes‐associated anemia than the Han, supporting the hypothesis that high‐altitude adaptations affecting blood and circulation intersect with chronic disease processes to lower risk for these outcomes. As chronic diseases continue to grow as global health concerns, it is important to investigate how they may be affected by local genetic adaptations.Accepted manuscrip

Exploring the place of arts-based approaches in early childhood education research

Defined broadly as the use of art forms – music, drama, music, painting, storying and so on – to create privileged insight into educational policies and practices, Arts-Based Educational Research [ABER] techniques have started to have some, albeit limited, purchase on the mainstream of educational enquiry; there is less evidence, however, of their use in early childhood research. This article critically outlines some chief characteristics of an ABER approach, its claim to legitimacy in the currency of qualitative research practice and the issues which presently both drive and challenge it. An example from our own work is given, and the essay concludes with a prospectus of critical issues, questions and exhortations

Cultural Contestation in China: Ethnicity, Identity and the State

This chapter explores how the political-administrative design of the Chinese state, characterized as “multi-level governance”, might be the cause of more subtle forms of resistance. By looking at the formulation of heritage policies of Lancang County, Christina Maags illustrates how the administrative fragmentation resulted in both administrative contestation and cultural contestation, with a threatened local identity at its core
