The Aboriginal people of the Upper Finke River in central Australia have followed a literacy tradition for over 130 years. When the first Lutheran missionaries arrived, they immediately started to study the local Arandic language and were teaching reading and writing by 1879. Despite this long exposure to literacy and the Lutheran influence on it, the issue of the right orthography for this Arandic language variety is emotionally charged and politically very contested. In this post‐colonial context, orthography has become a sociocultural and symbolic, rather than a phonemic, matter.  相似文献

ABSTRACT

This paper traces the engagement of Graham Greene's novel A Burnt-Out Case with traditional discourses of leprosy (the biblical ‘leper’ as a sinner, missionary care, tropical medicine, Albert Schweitzer's hospital in Lambaréné, germ theory), and shows how it suggests an ethics of care which highlights the psychosocial aspects of disease and healing. The paper argues that the reception of the novel opened a discursive space for the re-negotiation of images of leprosy after empire, making visible the structures and agents of global public health communication and their diverging conceptions of explanatory authority, scientific accuracy and the relation of science and literature. The article incorporates archival sources from press reviews to draft versions of the novel and the author's correspondence with prominent leprosy experts. It draws on media and science communication studies, disability studies and on contributions to the sociology of knowledge by Ludwik Fleck, Thomas Kuhn and Bruno Latour.  相似文献

Binfield, P., Archer, M., Hand, S.J., Black, K.H., Myers, T.J., Gillespie, A.K. & Arena, D.A., June 2016. A new Miocene carnivorous marsupial, Barinya kutjamarpensis (Dasyuromorphia), from central Australia. Alcheringa 41, xx–xx. ISSN 0311-5518.

A new dasyuromorphian, Barinya kutjamarpensis sp. nov., is described on the basis of a partial dentary recovered from the Miocene Wipajiri Formation of northern South Australia. Although about the same size as the only other species of this genus, B. wangala from the Miocene faunal assemblages of the Riversleigh World Heritage Area, northwestern Queensland, it has significant differences in morphology including a very reduced talonid on M4 and proportionately wider molars. Based on the structural differences and the more extensive wear on its teeth, the central Australian species might have consumed harder or more abrasive prey in a more silt-rich environment than its congener, which hunted in the wet early to middle Miocene forests of Riversleigh.

ABSTRACT

This paper explores to what extent organic initiatives that go beyond mainstream organic (so-called Organic 3.0) can challenge the corporate food regime and how they can push the food system towards sustainability transformations. We depart from the assumption that individual initiatives may differ in their potential to influence the corporate food regime and that this potential can be assessed by examining traits linked to reformist, progressive or radical food regime/food movement trends that they may possess. Rather than establishing a dichotomy between niche and food regime or categorizing Organic 3.0 initiatives within one of these trends, we explore the nuances in niche–regime relationships within the food system from a multi-level perspective, using the cases of two Organic 3.0 initiatives in Sweden. The results show that relations between these initiatives and the food regime share key characteristics, but also differ in important respects. While a reformist strategy facilitates niche growth, progressive and radical approaches are more likely to challenge the regime. The choice of approach in both cases involves trade-offs between growth and organic values. We conclude that one of the primary roles of Organic 3.0 initiatives may be to illustrate the viability of alternative models.  相似文献
