Despite the position of the United States as de facto global hegemon, China is a rising power in the world. As Chinese power grows, the projection of Chinese influence will be felt most acutely in Southeast Asia. Whether to accommodate, contain or resist China will depend on future developments that none can foresee, including Chinese ambitions, the policies of other international players (the U.S., Japan), and the cohesion or fragility of the Association of Southeast Asia Nations (ASEAN). This paper argues that in deciding how best to deal with China, two factors that will influence the countries of Southeast Asia are their own long histories of bilateral relations with China and their own differing conceptions of how foreign relations should be conducted. This is to argue that history and culture are central to any understanding of the likely future shape of China-Southeast Asia relations. Only by taking history and culture into account will analysts be in a position to predict how the mainland and maritime states of Southeast Asia are likely to respond to a more powerful, confident and assertive China.

South Asia's pursuit of economic development has entailed considerable damage to and exposed the fragility of the physical environment of the region. This paper provides an analytical overview of the of the environmental problem that manifest themselves in South Asia in a comparative perspective with East and Southeast Asian countries as well as selected developed market economics. To date, South Asian development process has been environment-intensive and environment-depleting. It is argued that environmental problems are likely to set serious constraints to sustain growth in production to support a growing population. By exploring the relationship between indices of human welfare and bio-diversity conservation. the paper exposes the dichotomy of the development process. Finally, the study underscores the need for a range of policy options that rely both based and non-market based instruments in an integrated setting to enviromnentalize South Asian economic development.

Third sector organizations are transitioning towards entrepreneurial and managerial models as a result of quasi-market strategies. This paper reports on the research findings of a survey of nonprofit disability organizations in Queensland and Victoria impacted upon by quasi-market reform. Enterprising organizations were found to have made substantial change to organizational structures and systems, whilst more traditional organizations made few changes. All organizations demonstrated commitment to a social justice ethos. However across the organizational archetypes there were reports of an organizational 'fragility'. It is argued that the problems of sustainability of community service organizations that existed prior to quasi-market reforms remain. This implies community service organizations will experience ongoing difficulties in the post-market era without further rationalization and change. A conceptual framework for sustainability of the community service sector is presented at the policy and organizational level.

Peak adolescent fracture incidence at the distal end of the radius coincides with a decline in size-corrected BMD in both boys and girls. Peak gains in bone area preceded peak gains in BMC in a longitudinal sample of boys and girls, supporting the theory that the dissociation between skeletal expansion and skeletal mineralization results in a period of relative bone weakness. Introduction: The high incidence of fracture in adolescence may be related to a period of relative skeletal fragility resulting from dissociation between bone expansion and bone mineralization during the growing years. The aim of this study was to examine the relationship between changes in size-corrected BMD (BMDsc) and peak distal radius fracture incidence in boys and girls. Materials and Methods: Subjects were 41 boys and 46 girls measured annually (DXA; Hologic 2000) over the adolescent growth period and again in young adulthood. Ages of peak height velocity (PHV), peak BMC velocity (PBMCV), and peak bone area (BA) velocity (PBAV) were determined for each child. To control for maturational differences, subjects were aligned on PHV. BMDsc was calculated by first regressing the natural logarithms of BMC and BA. The power coefficient (pc) values from this analysis were used as follows: BMDsc = BMC/BA(pc). Results: BMDsc decreased significantly before the age of PHV and then increased until 4 years after PHV. The peak rates in radial fractures (reported from previous work) in both boys and girls coincided with the age of negative velocity in BMDsc; the age of peak BA velocity (PBAV) preceded the age of peak BMC velocity (PBMCV) by 0.5 years in both boys and girls. Conclusions: There is a clear dissociation between PBMCV and PBAV in boys and girls. BMDsc declines before age of PHV before rebounding after PHV. The timing of these events coincides directly with reported fracture rates of the distal end of the radius. Thus, the results support the theory that there is a period of relative skeletal weakness during the adolescent growth period caused, in part, by a draw on cortical bone to meet the mineral demands of the expanding skeleton resulting in a temporary increased fracture risk.
