This article examines the social effects of contract farming of export horticulture among smallholders in Meru District, Kenya. During the 1980s and 1990s, contracting was popularized by donors and governments alike as a way to reduce poverty and increase opportunities for self–employment in rural areas. Considerable research has documented the tensions in social relations that emerge in such cases, giving rise to gendered struggles over land, labour, and income in the face of new commodity systems. This article highlights similar tendencies. It suggests that men’s failure to compensate their wives for horticulture production has given rise to a string of witchcraft allegations and acts, as the wealth engendered by horticultural commodities comes up against cultural norms of marital obligation. While witchcraft accusations can expose women to risks of social alienation and financial deprivation, witchcraft nevertheless remains a powerful weapon through which women can level intra–household disparities and, more broadly, challenge the legitimacy of social practice. In Meru, witchcraft discourses are a vehicle through which gendered struggles over contract income are articulated and contested, and through which the social costs of agrarian transition become apparent. 相似文献

The aim of this proposal is to present an original approach to the study and preservation of rock art caves. A multidisciplinary study of cave wall alteration will be performed to understand the impact of environmental context on the evolution of wall surfaces. The approach involves the choice of a cave with characteristics similar to painted caves in the studied area (Vézère Valley in Dordogne, France): e.g., cave wall alteration, lithology, morphology, etc. This selected cave is intended to become a laboratory cave, monitored for the acquisition of chemical, physical and biological environmental data on bedrock, air and fluids along with their characteristics. A cave without art or archaeological interest has been chosen specifically to conduct experiments, to make in situ analysis and to obtain samples. The results are to be completed by specific observations in several other caves and compiled in a database. 相似文献

Freezing and melting behaviors of H2O‐NaCl‐CaCl2 solutions in fused silica capillaries and glass‐sandwiched films: implications for fluid inclusion studies 下载免费PDF全文
Fluid inclusions of the H2O‐NaCl‐CaCl2 system are notorious for their metastable behavior during cooling and heating processes, which can render microthermometric measurement impossible or difficult and interpretation of the results ambiguous. This study addresses these problems through detailed microscopic examination of synthetic solutions during cooling and warming runs, development of methods to enhance nucleation of hydrates, and comparison of microthermometric results with different degrees of metastability with values predicted for stable conditions. Synthetic H2O‐NaCl‐CaCl2 solutions with different NaCl/(NaCl + CaCl2) ratios were prepared and loaded in fused silica capillaries and glass‐sandwiched films for microthermometric studies; pure solutions were used with the capillaries to simulate fluid inclusions, whereas alumina powder was added in the solutions to facilitate ice and hydrate crystallization in the sandwiched samples. The phase changes observed and the microthermometric data obtained in this study have led to the following conclusions that have important implications for fluid inclusion studies: (i) most H2O‐NaCl‐CaCl2 inclusions that appear to be completely frozen in the first cooling run to ?185°C actually contain large amounts of residual solution, as also reported in some previous studies; (ii) inability of H2O‐NaCl‐CaCl2 inclusions to freeze completely may be related to their composition (low NaCl/(NaCl + CaCl2) ratios) and lack of solid particles; (iii) crystallization of hydrates, which is important for cryogenic Raman spectroscopic studies of fluid inclusion composition, can be greatly enhanced by finding an optimum combination of cooling and warming rates and temperatures; and (iv) even if an inclusion is not completely frozen, the melting temperatures of hydrohalite and ice are still valid for estimating the fluid composition. 相似文献

Policy makers and advocates of joint forest management (JFM) agree that women should be full participants and that their involvement is especially important because of the nature of women's work. This article examines how JFM policy has addressed gender in India. It argues that policy has been informed by instrumentalist positions in the debate over women's relationship to the environment. Consequently, gender planning in JFM has focused on two issues: formal representation for women in local institutions, and identifying women's ‘special’ values, knowledge and uses of forest resources. The scant evidence suggests that the impact of JFM on women has generally been negative. Finally, the article suggests that gender policy in JFM needs to be based on a more sophisticated understanding of gender relations and a wider examination of the gendered context of JFM processes. 相似文献

This paper examines the new presence of "culture" within politics in Northern Ireland and attempts by cultural policymakers and community activists to constructively shift the meanings of "identity", "tradition" and "heritage". It focuses on the work of the Community Relations Council and the strategic development of its three principles of equity, diversity and interdependence, in relation to specific controversies about culture in Northern Ireland and wider debates about pluralism and multiculturalism. The distinctive configuration of questions of pluralism and culture in Northern Ireland highlights the ways in which multicultural theory is shaped by its geographies of development and circulation and how ideas of culture and multiculture work in different places and travel with sometimes ambiguous effects. At the same time, the pragmatic combination of optimism, realism, encouragement and critique in cultural policy in a context of continued division and political instability complicates familiar accounts of the geographies and politics of multiculture. 相似文献
