Campfire culture and computer culture: Museums of the present

In Australia indigenous peoples have never had a treaty with the dominant cultures; and their on-going marginalisation is some testimony to this. However, they have not languished entirely in a policy free environment: media is one area where some policy advances have been made; but media policy development has experienced a number of problems. It has tended to be monolithic in a situation demanding multi and complex treatments. And funding, as always, never seems sufficient to meet those multi and complex needs. This paper examines a small remote community on the island of Milingimbi off the northern coast of Arnhem Land in Australia's far north. People in East Arnhem Land refer to themselves collectively as Yolngu. This community is not typical of many documented cases of media relations between indigenous and non-indigenous peoples; however, the fact that it tends to overturn much of the conventional scholarship surrounding indigenous peoples and the media, helps shed new light on the inadequacy of not only monolithic media policy, but the inadequacy of media-only approaches to policy. Arguably, the significance of the media in Milingimbi is part of a 'triangulated' relationship between indigenous and dominant cultures. That triangulation also involves appropriate forms of government and education, which coupled with appropriate media appear to offer new ways of seeing self-government alongside relative cultural and economic autonomy.

Relationship between the microcirculation and the pathological changes in the spradic and variant forms of Creutzfeldt-Jakob Disease (CJD)

This chapter is concerned with the influence of the brain microcirculation on the development of the pathological changes in Creutzfeldt-Jakob disease (CJD). Hence, the spatial correlations between the vacuolation, prion protein (PrP) deposits, and the blood vessel profiles were studied in immunolabelled sections of the cerebral cortex, hippocampus, and cerebellum in two subtypes of CJD, viz., sporadic Creutzfeldt-Jakob disease (sCJD) and variant CJD (vCJD). In sCJD, both the vacuolation and the ‘synaptic-type’ PrP deposits were spatially correlated with the blood vessels; the PrP deposits being the more strongly correlated than the vacuoles. In vCJD, there were no significant spatial correlations between either the vacuolation or the diffuse-type of PrP deposit and the microvessels. By contrast, a consistent pattern of spatial correlation was observed in gyri of the cerebral cortex between the florid PrP deposits and blood vessels. In both sCJD and vCJD, the frequency of positive spatial correlations was similar in the different gyri of the cerebral cortex and in the upper compared with the lower laminae. In conclusion, the microcirculation appears to be more significantly involved in determining the pathological changes in sCJD than in vCJD. The spatial correlations of the florid PrP deposits in vCJD and the synaptic deposits in sCJD and the blood vessels may be attributable to factors associated with the microcirculation which enhance the aggregation of PrP molecules rather than representing a possible haematogenous spread of the disease.

Effects of government regulations, market orientation and ownership structure on corporate social responsibility in China:an empirical study

Previous research on corporate social responsibility mainly focuses on its nature and impact on business performance. This paper reports on a study that contributes to our understanding of the determinants of corporate social responsibility by focusing specifically on the role played by three strategically important variables, namely government regulation, ownership structure and market orientation. Results of a survey of 586 general managers of hotels in China suggest that the market orientation is the most significant predicator of corporate social responsibility followed by government regulation. In contrast, the ownership structure is found to have little effect. The implications of the findings for managers in China are discussed.

Developing a market orientation in a transitional economy:the role of government regulation and ownership structure

In this article, the authors report the findings of an exploratory study that examines the challenges of developing a market orientation in China, the world’s largest transitional economy. The findings suggest that though managerial actions are relevant, in transitional economies, environmental factors—most notably, government policies—are a major influence on firms’ aspirations to be market oriented.

Increased expression of phosphorylated forms of RNA-dependent protein kinase and eukaryotic initiation factor 2 alpha may signal skeletal muscle atrophy in weight-losing cancer patients

Previous studies suggest that the activation (autophosphorylation) of dsRNA-dependent protein kinase (PKR) can stimulate protein degradation, and depress protein synthesis in skeletal muscle through phosphorylation of the translation initiation factor 2 (eIF2) on the alpha-subunit. To understand whether these mediators are important in muscle wasting in cancer patients, levels of the phospho forms of PKR and eIF2alpha have been determined in rectus abdominus muscle of weight losing patients with oesophago-gastric cancer, in comparison with healthy controls. Levels of both phospho PKR and phospho eIF2alpha were significantly enhanced in muscle of cancer patients with weight loss irrespective of the amount and there was a linear relationship between phosphorylation of PKR and phosphorylation of eIF2alpha (correlation coefficient 0.76, P=0.005). This suggests that phosphorylation of PKR led to phosphorylation of eIF2alpha. Myosin levels decreased as the weight loss increased, and there was a linear relationship between myosin expression and the extent of phosphorylation of eIF2alpha (correlation coefficient 0.77, P=0.004). These results suggest that phosphorylation of PKR may be an important initiator of muscle wasting in cancer patients.

Pathological changes in the sporadic and variant forms Of Creutzfeldt-Jakob Disease (CJD) are spatially related to blood vessels

The objective of this article was to determine whether the pathological changes of Creutzfeldt-Jacob disease (CJD) were related to the brain microcirculation. Hence, the spatial correlations between the vacuolation, prion protein (PrP) deposits, and the blood vessel profiles were studied in immunolabelled sections of the cerebral cortex, hippocampus, and cerebellum in two subtypes of CJD, viz., sporadic CJD (sCJD) and variant CJD (vCJD). In sCJD, both the vacuolation and the ‘synaptic-type’ PrP deposits were spatially correlated with the microvessels; the PrP deposits being more strongly correlated than the vacuoles. In vCJD, there were no significant spatial correlations between either the vacuolation or the diffuse-type of PrP deposit and the microvessels. By contrast, a consistent pattern of spatial correlation was observed in gyri of the cerebral cortex between the florid PrP deposits and microvessels. In both sCJD and vCJD, the frequency of positive spatial correlations was similar in the different gyri of the cerebral cortex and in the upper compared with the lower laminae. In conclusion, the microcirculation may be more significantly involved in determining the pathological changes in sCJD than in vCJD. The spatial correlations of the florid PrP deposits in vCJD and the synaptic deposits in sCJD and the blood vessels may be attributable to factors associated with the microcirculation which enhance the aggregation of PrP molecules rather than representing a possible haematogenous spread of the disease.

Objects and the production of technological forms of life:understanding organisational arrangements from a postsocial perspective

Objects are produced within, and simultaneously affect, the process of organizing as a consequence of their interaction within social collectives. This paper discusses the impact and influences of the growth of post-social relations, between human and technological objects, on social and organisational arrangements. The paper presents a discussion largely at the conceptual level and draws from a variety of literatures, including the burgeoning sociology of science literature. The discussion in this paper is based on a view that posits the growth of intimate links with epistemic objects within organisations and society. Organising through networks of post-social relations increasingly comes to affect the manner in which differing groups of organisational participants, and particularly various categories of knowledge workers, experience time and spatial arrangements within organisations.
