Physical Activity of Remote Indigenous Australian Women: A Postcolonial Analysis of Lifestyle

In the context of rising chronic diseases amongst Indigenous peoples, there are calls for the adoption of more healthy “lifestyles.” In this context, this paper explores thoughts about physical activity from 21 Indigenous families through the voices of women and girls living in remote rural communities in the Torres Strait and Northern Peninsula Area, Australia. Speaking back to physical activity as a lifestyle “choice,” three consistent themes emerged: shame, gendered positioning, and welfarism. In conclusion, the perspectives of Torres Strait islanders and Northern Peninsula Area communities suggest that there are deeply embedded ways of thinking about the body, familial obligations, and the provision of and access to being active that are not consistent with Western health policies predicated upon individuals shouldering responsibility for “taking exercise.”     

The relationships between stress,health, and physically active leisure as a function of life‐cycle

This article examines relationships between stress, health, and participation in physically active leisure using data collected as part of the 1985 and 1990 U.S. National Health Interview Surveys (NHIS). In particular, the article analyzes: (a) the effects of life‐cycle progression (controlled for gender) on subjectively perceived stress and self‐reported health; (b) the role of physically active leisure in enhancing health or buffering adverse health outcomes of stress; and (c) the effects of selected social‐economic factors, such as education and income, on the relationships between life‐cycle, stress, health, and physically active leisure. According to our analyses: (1) stress is unevenly distributed across the life span; (2) stress‐reducing effects of physically active leisure are present among retired older people more so than in the middle‐aged life‐cycle groups; and (3) direct health‐enhancing effects of participation in physically active leisure are more evident than the buffering effects of leisure on stress‐health relationships. A critical discussion of methodological and substantive issues facing researchers interested in the relationships between leisure, stress, and health is provided.     

Recreation and Leisure Research from an Active Living Perspective: Taking a Second Look at Urban Trail Use Data

This paper examines recreation and leisure research within the context of active living, and highlights an apparent gap between the current involvement of recreation and leisure researchers and the potential they could offer to this important and expanding area of inquiry. To illustrate this potential, I looked at two previous studies that focused on the recreational use of urban trails and reanalyzed the data from an active living perspective. In Study 1, individual, social and environmental factors helped distinguish between low, moderate, and high activity level trail uses. In Study 2, use patterns helped distinguish between health-motivated trail users and individuals using trails for recreation and other purposes, but perceptual and demographic data were similar among groups. Findings from similar studies can help inform active living research, and recreation and leisure studies can provide leadership and contributions to a transdisciplinary understanding of active living.

Capacity Depreciation, Implicit Rental Price, and Investment Demand for Farm Tractors in Canada

Among the different factors pertaining to the demand for durable inputs in agriculture, the way the input depreciates over time is an important issue. This study investigates four alternative capacity depreciation patterns for farm tractors. While published estimates from government agencies implicitly assume convex capacity depreciation patterns, the results of this study demonstrate that the use of agricultural engineering data which depict a concave rather than convex pattern better reflect farmers' investment decisions. An implicit rental price measure is also proposed to account for the fact that the purchase price of a durable input is not an appropriate measure of the implicit rental cost of the asset.
Parmi les facteurs déterminants de la demande pour les biens durables en agriculture, la rapidité avec laquelle I'intrant se déprécie est certainement importante lors des décisions d'investissement. La présente etude analyse quatre différents scénarios de dépréciation pour les tracteurs agricoles au Canada. Bien que les données publiées par les agences gouver-nementales supposent implicitement que les biens durables se déprécient à un taux annuel constant, les résultats de cette etude montrent que I'utilisation de données basées sur la valeur productive de I'intrant telle que calculée sur une base expkrimentale donne de meil-leurs résultats statistiques dans I'estimation de la demande pour les tracteurs agricoles. De plus, une mesure du coût implicite de I'intrant est également proposée pour tenir compte du fait que le prix d'achat n'est pas une mesure appropriée dans I'analyse de la demande pour un bien durable.
