The vicuña Vicugna vicugna is a wild South American camelid with a fiber so highly valued that the species was hunted almost to extinction. Strict conservation regulations and international treaties have been successful in causing vicuña populations to recover to a level where it is now possible to develop “sustainable use” programs. In Chile, Bolivia, Peru, Ecuador, and Argentina, vicuña management plans have been developed, with differing biological and socioeconomic implications. The major issue is whether vicuña are managed in the wild or in captivity. The aim of this paper is to examine the forces that have, in recent years, shaped policies concerning vicuña management, and especially the underlying conflict between economic growth and conservation. The analysis draws largely on primary data from Argentina and a report written by the U.S. Department of the Interior, Fish and Wildlife Service concerning the reclassification of vicuña from endangered to threatened. This report is important both directly (because FWS is the key advisory body to the U.S. government and the United States is a major potential market for the fiber), and indirectly, because the views of the United States and its advisers will in turn have a major influence on other actors.  相似文献

The AIDS epidemic will cause significant increases in illness and death in prime‐age adults, which will manifest itself through negative social, economic and developmental impacts. The epidemics economic impacts at the household level are decreased income, increased health‐care costs, decreased productive capacity and changing expenditure patterns. Three coping strategies are observed: altering household composition; withdrawing savings or selling assets; and receiving assistance from other households. Following death, the impacts break out of the family into the community, primarily through orphaning. In the near future, the sheer number of orphans may overwhelm the capacity of existing community resources to cope. The distribution of the impacts of the AIDS epidemic falls unevenly among the genders. In Africa, women have higher infection rates and bear a disproportionate burden of the care of HIV‐positive people. Orphaned girls are more vulnerable to exploitation.  相似文献

Despite an increasing literature on the decomposition of human remains, whether buried or exposed, it is important to recognise the role of specific microenvironments which can either trigger or delay the rate of decomposition. Recent casework in Northern England involving buried and partially buried human remains has demonstrated a need for a more detailed understanding of the effect of contrasting site conditions on cadaver decomposition and on the microenvironment created within the grave itself. Pigs (Sus scrofa) were used as body analogues in three inter-related taphonomy experiments to examine differential decomposition of buried human remains. They were buried at three contrasting field sites (pasture, moorland, and deciduous woodland) within a 15 km radius of the University of Bradford, West Yorkshire, UK. Changes to the buried body and the effect of these changes on hair and associated death-scene textile materials were monitored as was the microenvironment of the grave. At recovery, 6, 12 and 24 months post-burial, the extent of soft tissue decomposition was recorded and samples of fat and soil were collected for gas chromatography mass spectrometry (GCMS) analysis. The results of these studies demonstrated that (1) soil conditions at these three burial sites has a marked effect on the condition of the buried body but even within a single site variation can occur; (2) the process of soft tissue decomposition modifies the localised burial microenvironment in terms of microbiological load, pH, moisture and changes in redox status. These observations have widespread application for the investigation of clandestine burial and time since deposition, and in understanding changes within the burial microenvironment that may impact on biomaterials such as hair and other associated death scene materials.  相似文献

There are two sets of annual mortality statistics released by the Central Statistics Office (CSO) in Ireland, one based on deaths registered in the particular year and the other based on the deaths that occurred in that year. We compared the registration and occurrence figures for suicide and for other deaths by an external cause for the years 1987-2003. The occurrence figures were, on average, 6% higher than the registration figures. There was evidence that the extent of the discrepancy increased over the study period, reaching almost 20% in recent years. The findings suggest that caution needs to be taken in the media reporting of registration figures for suicide and other external causes of death in Ireland and in the interpretation of these figures by health professionals.  相似文献

This article explicates John Goldthorpe's recent analytical distinction between ‘corporatist’ and ‘dualist’ tendencies in Western political economies. By linking these categories to macro‐economic strategies, the role of trade unions and the circumstances under which state policy is initiated, this dichotomy can be of value in the analysis of these polities. The article examines the major characteristics of British and Swedish labour market policy in the areas of wage policy, trade unions and training and education as they relate to the respective macro‐economic policies adopted by British and Swedish governments. These provide examples of the presence and development of corporatist and dualist tendencies in these two countries.  相似文献

Children are overrepresented in households with intimate-partner violence (IPV), and many suffer the double burden of being the subject of maltreatment and bearing the consequences of abuse to their mothers. Despite this situation, little information exists concerning parenting by women who have been abused by an intimate partner. We examine the relationship between women’s experiences with IPV and the quality of maternal parenting using data from the National Survey of Child and Adolescent Well-Being. The sample consisted of 1,943 female caregivers of children younger than 10 years investigated for child maltreatment. Women who had experienced IPV in the past but were no longer victims of IPV had significantly better parenting scores than women who were currently experiencing IPV, when other risk factors were controlled. This study adds to the evidence that IPV does not necessarily impair maternal parenting. Women abused by an intimate partner deserve a thorough assessment of what services they need: parenting services should be offered as warranted on a case-by-case evaluation of the particular woman’s parenting skills.  相似文献
