Possibility of dying as a unified explanation of why we discount the future, get weaker with age, and display risk-aversion

I formulate a simple and parsimonious evolutionary model that shows that because most species face a possibility of dying because of external factors, called extrinsic mortality in the biology literature, it can simultaneously explain (a) why we discount the future, (b) get weaker with age, and (c) display risk-aversion. The paper suggests that testable restrictions—across species, across time, or across genders—among time preference, aging, and risk-aversion could be analyzed in a simple framework .     

Spirituality in Social Work: A Survey of Students at South African Universities

Academic discourse related to spirituality has proliferated globally. The rationale for its inclusion in social work education rests on the premise that spirituality is a critical strength in social work practice. This paper explores this aspect and highlights empirical research related to the inclusion of spirituality in training. It does this within the context of a SA study that was undertaken to explore the views of students with regard to the role of religion and spirituality in practice and the extent to which South African curricula considers religion and spirituality. The research was conducted by distributing questionnaires to final year social work students at schools of social work (N = 21); 342 completed surveys were returned yielding a response of 47%. The findings revealed high levels of religiosity or spirituality amongst students, a gap in the curriculum on spirituality and support for its inclusion in social work education.
