Is there a divide between local medicinal knowledge and Western medicine? a case study among native Amazonians in Bolivia

Background: Interest in ethnomedicine has grown in the last decades, with much research focusing on how local medicinal knowledge can contribute to Western medicine. Researchers have emphasized the divide between practices used by local medical practitioners and Western doctors. However, researchers have also suggested that merging concepts and practices from local medicinal knowledge and Western science have the potential to improve public health and support medical independence of local people. In this article we study the relations between local and Western medicinal knowledge within a native Amazonian population, the Tsimane'. Methods: We used the following methods: 1) participant observation and semi-structured interviews to gather background information, 2) free-listing and pile-sorting to assess whether Tsimane' integrate local medicinal knowledge and Western medicine at the conceptual level, 3) surveys to assess to what extent Tsimane' combine local medicinal knowledge with Western medicine in actual treatments, and 4) a participatory workshop to assess the willingness of Tsimane' and Western medical specialists to cooperate with each other. Results: We found that when asked about medical treatments, Tsimane' do not include Western treatments in their lists, however on their daily practices, Tsimane' do use Western treatments in combination with ethnomedical treatments. We also found that Tsimane' healers and Western doctors express willingness to cooperate with each other and to promote synergy between local and Western medical systems. Conclusion: Our findings contrast with previous research emphasizing the divide between local medical practitioners and Western doctors and suggests that cooperation between both health systems might be possible

An Estimate of Avian Mortality at Communication Towers in the United States and Canada

Avian mortality at communication towers in the continental United States and Canada is an issue of pressing conservation concern. Previous estimates of this mortality have been based on limited data and have not included Canada. We compiled a database of communication towers in the continental United States and Canada and estimated avian mortality by tower with a regression relating avian mortality to tower height. This equation was derived from 38 tower studies for which mortality data were available and corrected for sampling effort, search efficiency, and scavenging where appropriate. Although most studies document mortality at guyed towers with steady-burning lights, we accounted for lower mortality at towers without guy wires or steady-burning lights by adjusting estimates based on published studies. The resulting estimate of mortality at towers is 6.8 million birds per year in the United States and Canada. Bootstrapped subsampling indicated that the regression was robust to the choice of studies included and a comparison of multiple regression models showed that incorporating sampling, scavenging, and search efficiency adjustments improved model fit. Estimating total avian mortality is only a first step in developing an assessment of the biological significance of mortality at communication towers for individual species or groups of species. Nevertheless, our estimate can be used to evaluate this source of mortality, develop subsequent per-species mortality estimates, and motivate policy action

In praise of the everyday: Trust and the art of social living in an Amazonian community

The article states the high evaluation that an Amazonian people, the Piaroa, place upon the artful skills of everyday existence. It is argued that their emphasis upon the creativity of daily practice is forthcoming from a powerful and egalitarian social philosophy. The difficulties of translating such a philosophy, where the human self is contextualised within a wider cosmic setting, are raised. The aim of translation would be to enable us to engage in dialogue with the Piaroa about common concerns (upon the relation of the individual to the collectivity, for instance, or upon the idea of freedom, or the question of the relation of customs to rational decision making). These are a people who overtly shun the idea of a social rule, yet strongly value sociality, their own customs, and the mutuality of the ties of community. At the some time they demonstrate even more forcefully an 'obstinate individualism'. A major puzzle to be discussed is the notion that personal autonomy is understood as a social capacity, and a cultural one as well: the volitional 1, the social relation, and the cultural artifice are an associated set of values. The centrality of the notions of reflective reason and personal trust to this particular egalitarian ethics will be discussed.</p
