This paper has two aims: to explore approaches to the measurement of children's daily travel to school in a context of limited geospatial data availability and to provide data regarding school choice and distance travelled to school in Soweto-Johannesburg, South Africa. The paper makes use of data from the Birth to Twenty cohort study (n?=?1428) to explore three different approaches to estimating school choice and travel to school. First, straight-line distance between home and school is calculated. Second, census geography is used to determine whether a child's home and school fall in the same area. Third, distance data are used to determine whether a child attends the nearest school. Each of these approaches highlights a different aspect of mobility, and all provide valuable data. Overall, primary-school-aged children in Soweto-Johannesburg are shown to be travelling substantial distances to school on a daily basis. Over a third travel more than 3 km one way to school, 60% attend schools outside of the suburb in which they live, and only 18% attend their nearest school. These data provide evidence for high levels of school choice in Johannesburg-Soweto, and that families and children are making substantial investments in pursuit of high-quality educational opportunities. Additionally, these data suggest that two patterns of school choice are evident: one pattern involving travel of substantial distances and requiring a higher level of financial investment and a second pattern involving choice between more local schools, requiring less travel and a more limited financial investment.  相似文献

Although idealizations of motherhood are ever in flux, specific historical moments can be said to produce distinctive tropes of ‘good’ motherhood that have very real impacts on how women act and conceptualize themselves as mothers. This article examines good motherhood in its current iteration, and how now-common beliefs about breastfeeding are implicated in its construction. Furthermore, it looks at the ways in which idealizations of motherhood discipline the breastfeeding body so that it will fit into public space without disruption. I discuss the contradictory impacts of characterizations of the good mother as they appeared in the pro-breastfeeding dialogs that arose following a 2007 incident in which a mother was asked to cover herself up while nursing in a Kentucky restaurant. I posit that while these characterizations helped to make breastfeeding a more widely accepted public activity, they also had the effect of reifying a very narrow conception of what it means to be a good mother. I make this claim through an analysis of two common refrains heard in pro-public-breastfeeding arguments: breast milk is exceedingly healthy and mothers should not be persecuted if they nurse discreetly. Although these assertions together are compelling to the general public in that they provide a scientific justification for breastfeeding while at once assuaging fears of discomfort presented by a reproductive act being performed in a public space, I suggest that they also work to discipline women and maintain public-space-as-usual.  相似文献

Australia has had a long connection with, and significant national interests in, the Southern Ocean and Antarctica. The Australian Antarctic Territory comprises 42 per cent of Antarctica's landmass. Australia is not only a claimant state and original signatory to the Antarctic Treaty but has played a significant role in the development of what is termed the Antarctic Treaty System (ATS). This article aims to provide an overview of Australia's key policy interests and government policy goals towards Antarctica, including its commitment to the ATS. In examining key policy objectives we note that despite continuity and development of these objectives, significant changes and challenges have arisen in the period 1984–2006. It is these challenges that will help frame Australia's Antarctic agenda over the next 20 years and beyond.  相似文献

Mindfulness in its English rendering brings together a mix of historical influences, from Zen to Romanticism to yoga. Still, the most central concept from which it draws is sati, a Theravada Buddhist Pali term first translated as mindfulness over 100 years ago. This article reports on the findings of an ethnographic investigation of sati in the Theravada-majority countries of Thailand, Myanmar and Sri Lanka, where the concept is widely used for a range of religious, therapeutic and colloquial ends. Based on interviews and questionnaires involving over 600 monks, psychiatrists and lay Buddhist practitioners, the article explores aspects of sati that are not often recognized (or recognized as much) in Western, secular mindfulness contexts. These qualities include attention to memory in present-moment awareness, the potency of supernatural engagements and a social-ethical orientation towards living well. Highlighting these qualities allows for a greater appreciation of cultural diversity within contemporary global mindfulness practices and suggests possibilities for further developing the global therapeutic potential of mindfulness.  相似文献
