Microcredit is a concept that has gained widespread acceptance by international development agencies and major donors. It is viewed as a way to correct both governmental and market failure in Sub-Saharan Africa. Many view microcredit as a method for linking the formal and informal sectors of African economies to increase the reach of the formal sector. Extending the reach of the formal economy through microcredit is possible, and desirable, depending on macroeconomic reforms, respect for traditional financing relationships, and local control of institutions. However, very little has been done to determine the extent to which microcredit programs actually increase economic well-being. The model program, Grameen Bank of Bangladesh, has been studied and evaluated, but replications may not be inherently successful. The literature accepts that microcredit will increase economic well-being, if programs are correctly designed. Program design issues cannot be resolved, however, until economic well-being is measured and associated with specific designs.  相似文献

ABSTRACT

Based on research conducted as part of the Sydney Playground Project, this paper provides an exploratory investigation of the perspectives of girls relating to the ideal school playground experience, and whether their perspectives are influenced by a loose-parts playground intervention. The focus is on the play behaviours of 22 girls aged 8–10 years, from the perspective that school playgrounds are generally designed in ways that are more suited to the play behaviours of boys. The research is based on a qualitative analysis of children’s drawings, interviews and focus groups, exploring meanings associated with desired play experiences. Findings indicate that girls’ views of the ideal school playground are influenced by the geographies of the spaces they play in, and that girls highly valued changes provided by a loose-parts intervention.  相似文献

The Northeast is comprised of interior and coastal areas that were historically occupied by Iroquoians and Algonquians respectively. This brief review sets aside most Euroamerican historical archaeology and developments prior to A.D. 900 to concentrate on recent research that has dominated regional attention and is most likely to be of interest to archaeologists working elsewhere. The review argues that while Iroquoian archaeologists often work with or against broad controlling models of long standing, archaeologists in the Maritimes and New England more often focus on technical problems that are relevant to shared interests in broad topical issues. The contrast relates to both differences in the their databases and differences in how archaeological research is conceived.  相似文献

Previous aDNA research in the Southwest provides a framework to understand the Mimbres population which maintains a unique identity in the archeology of the desert Southwest of North America. Both the mitochondrial DNA (mtDNA) haplogroups and haplotypes of a sample of 46 Mimbres individuals were identified from skeletal remains and compared to those of other ancient and modern populations in the American Southwest and Mexico. The haplogroup frequency distribution of the Mimbres resembles that of other Southwestern populations, suggesting a close relationship between the Mimbres and the neighboring populations and population continuity for a long period of time. However, their relatively low frequency of haplogroup A (11% n = 5) is consistent with a clinal distribution of haplogroup A from Mesoamerica to the Southwest. Moreover, unlike other Southwestern populations, the Mimbres share haplotypes with populations to the south, such as the Cora, Huichol, and Nahua, suggesting gene-flow from Mesoamerica. Here we discuss this data in light of the origin of the Mimbres population and their relationship to other Southwestern and Mexican populations.  相似文献

Historical perspectives can be embedded into policy initiatives through a process of ‘past-proofing’—ensuring new policies take the study of the past into consideration. We describe how this was done in a project looking at patient access to general practice in the NHS. We argue that current preoccupations with timeliness which have led to the marginalisation of other dimensions of access are connected to a broader process of neo-liberal reform since the 1970s. This reflection can support a reframing of the terms of current debates on a major issue in British health care. It has wider implications for the policy relevance of history.  相似文献

This article examines the language used to justify a criminal prohibition on commercial surrogacy in Canada and Australia. I demonstrate that legislators in each country framed commercial surrogacy as an area over which there was national ‘consensus’ because of uniquely Canadian and Australian values. This was an effective political strategy, but for different reasons in each country: in Canada, because it fit with frames surrounding healthcare and anti-commercialisation, and in Australia, because the distinction between ‘altruistic’ and ‘commercial’ surrogacy mapped onto broader themes of altruism in Australian society. This suggests that the political use of national frames is especially successful when it taps into pre-existing narratives of what constitutes unacceptable behaviour in a given polity, and when it is attached to criminal prohibitions.  相似文献

Basic health system data such as the number of patients utilizing different health facilities and the types of illness for which they are being treated are critical for managing service provision. These data requirements are generally addressed with some form of national Health Management Information System (HMIS), which coordinates the routine collection and compilation of data from national health facilities. HMIS in most developing countries are characterized by widespread underreporting. Here we present a method to adjust incomplete data to allow prediction of national outpatient treatment burdens. We demonstrate this method with the example of outpatient treatments for malaria within the Kenyan HMIS. Three alternative modeling frameworks were developed and tested in which space–time geostatistical prediction algorithms were used to predict the monthly tally of treatments for presumed malaria cases (MC) at facilities where such records were missing. Models were compared by a cross-validation exercise and the model found to most accurately predict MC incorporated available data on the total number of patients visiting each facility each month. A space–time stochastic simulation framework to accompany this model was developed and tested in order to provide estimates of both local and regional prediction uncertainty. The level of accuracy provided by the predictive model, and the accompanying estimates of uncertainty around the predictions, demonstrate how this tool can mitigate the uncertainties caused by missing data, substantially enhancing the utility of existing HMIS data to health-service decision makers.  相似文献

Ancient DNA (aDNA) was extracted from the human remains of seventy-three individuals from the Tommy and Mine Canyon sites (dated to PI-II and PIII, respectively), located on the B-Square Ranch in the Middle San Juan region of New Mexico. The mitochondrial DNA (mtDNA) haplogroups of 48 (65.7%) of these samples were identified, and their frequency distributions were compared with those of other prehistoric and modern populations from the Greater Southwest and Mexico. The haplogroup frequency distributions for the two sites were statistically significantly different from each other, with the Mine Canyon site exhibiting an unusually high frequency of haplogroup A for a Southwestern population, indicating the possible influence of migration or other evolutionary forces. However, both sites exhibited a relatively high frequency of haplogroup B, typical of Southwestern populations, suggesting continuity in the Southwest, as has been hypothesized by others (8, 9, 29, 45 and 57). The first hypervariable region of twenty-three individuals (31.5%) was also sequenced to confirm haplogroup assignments and compared with other sequences from the region. This comparison further strengthens the argument for population continuity in the Southwest without a detectable influence from Mesoamerica.  相似文献
