A Covering Tour Model for Planning Mobile Health Care Facilities in SuhumDistrict, Ghama

The provision of adequate primary health care in developing countries is often troublesome. The problem is to provide a sufficient number of facilities to be geographically accessible, yet few enough to be properly stocked and staffed. In many less developed countries accessibility problems are exacerbated by extensive rainy seasons in which travel is only possible on paved roads. Using the covering tour model we investigate the use of mobile facilities to resolve this dilemma in Suhum District, Ghana. The model minimizes a mobile facility's travel while serving all population centers within range of a feasible stop. Computational results show that in the rainy season the model cannot provide full coverage; over six percent of the population is beyond a covering distance of eight kilometers. In the dry season, 99 percent of the population can be served by a tour at a covering distance of seven kilometers.Beyond a distance of four kilometers, the dry season problem becomes a trade-off between the distance traveled by healthcare patrons and mobile facilities. These results illustrate the importance of flexibility of mobile systems: if accessibility cannot be provided in all seasons it may still be provided at favorable times of the year.     

Recovery of DNA from archaeological insect remains: first results,problems and potential

We report the recovery of short fragments of PCR amplifiable ancient DNA from exoskeletal fragments of the grain weevil Sitophilus granarius (L.) extracted from Roman and medieval deposits in Northern England. If DNA preservation in archaeological insect remains is widespread then many applications in the spheres of evolutionary studies and archaeology can be conceived, some of which are outlined.     

Tibet and the Problem of Radical Reductionism

Abstract:  This article takes issue with a mode of argumentation advanced by a number of left-leaning, radical scholars, including those associated with China's New Left, about the causes of the Tibetan unrest in China in spring 2008. According to this stance, the Tibetan protests were the result of external manipulation by neoconservative, reactionary forces, ranging from the CIA to the Dalai Lama. The unstated premise of this response is that taking a critical stance against western imperialism and neoliberal globalization necessitates a defense of China's policies in Tibet. Such arguments take the form of unfavorable comparisons between Tibetans and Palestinians especially because the former are often romanticized, suggestions that Tibetans are unfortunate ideological victims of US-funded propaganda, and claims that they should be grateful for Chinese state-funded development. This response renders Tibetans incapable of being authentic political subjects. A radical stance on Western imperialism and capitalism should reject such reductionism.     

Transnational environmentalism and entanglements of sovereignty: The tiger campaign across the Himalayas

In the spring of 2006, Tibetans in China set fire to more than a million dollars worth of otter, leopard and tiger pelts. The numerous bonfires were a response to the 14th Dalai Lama's statement, made at the Kalachakra Initiation Ceremony in India, that Tibetans should cease wearing such pelts. The Chinese state interpreted this as an act of loyalty to the Dalai Lama and this evidence of multiple overlapping sovereignties as a threat to its exclusive territorial sovereignty. An effort to clarify this space invited a sovereign invocation of the exception, as salaried employees were forced to wear endangered animal pelts, violating Chinese national law. A conjunctural analysis of the Dalai Lama's speech and the subsequent burnings demonstrates that contrary to prevailing narratives, transnational environmental advocacy played a key role. The conjuncture in which these events took place was shaped by multiple competing entanglements of Chinese, Indian, and Tibetan sovereignties with nature protection and transnational activism. Two distinct assemblages, shaped by power relations and the politics of sovereignty, formed around protecting the tiger across the Himalayas, with dramatically different effects. The case shows that far from post-sovereign environmental governance, nature and sovereignty remain inextricably entangled, and illustrates how multiple modes to construct and defend state sovereignty come into conflict with each other.
