Research on coalitions in the policy process has found evidence of both short-term and long-term coalitions. Two possible methodological reasons for the varied results are that (1) there has been little systematic longitudinal research on the topic, and (2) most scholars have not distinguished situations where fundamental versus secondary interests are at stake. This article addresses both points by first applying the Advocacy Coalition Framework (ACF), which distinguishes fundamental from secondary beliefs/interests, and then performing a quantitative analysis of the content of organizations' testimonies regarding automotive pollution control over 26 years. Consistent with the ACF, we find that coalitions of interest groups, legislators, local governments, and agencies are relatively stable over time, despite two potentially disruptive events—the 1973–74 Oil Embargo and the 1980 Elections. On the other hand, there is little support for the ACF's hypothesis that broader beliefs will be more stable than narrower secondary beliefs. Our systematic methodology also enables us to separate the general pattern of stability from interesting exceptions of instability.  相似文献

This essay examines what factors led the first clerical wives to marry former Catholic clergy and nuns to marry in the first decade of the Reformation in Germany and seeks to explain the difference that social class, geography and gender made in those decisions. In contrast to the later Reformation, when pastors married same or higher social status women, the majority of women who married former priests and monks during the 1520s were often lower or, in the case of nuns, significantly higher social status than their husbands. Women married clergy for a variety of reasons that were counterintuitive to typical marital strategies for economic security and social networking, since clergy had neither in the 1520s. While sharing a common experience, clerical wives' reasons for marriage to a pastor varied greatly depending on class, local decision about the Reformation and numerous personal factors. Using a variety of sources including letters, civic records, court testimony and published pamphlets, this article demonstrates that these women did exhibit a limited agency that ultimately helped shape larger social and political acceptance of clerical marriage.  相似文献

The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented mostly use of local sources of stone. Here we investigate the raw material selection and transport behaviors of Oldowan hominins reflected in the stone artifact assemblages from the Kanjera South Formation, South Rachuonyo District, Kenya. Using geochemical methods (ED-XRF) artifacts are linked to primary and secondary source outcrops throughout southwestern Kenya. These data show that hominins selected raw materials for transport at frequencies that are significantly different from their availability on ancient landscapes. Furthermore, a substantial proportion of the assemblage represents transport over relatively long distances (>10 km). Our study further suggests that in the early stages of stone tool use hominins used a wide variety of raw materials and selected these materials at some distance from their eventual discard locations. Early hominin behavior may have incorporated an understanding of raw material source distributions across a more extensive landscape than has been previously documented. This supports the growing perspective that Oldowan technology represents a more complex behavioral pattern than is usually associated with the beginnings of hominin tool use.  相似文献

We present the combination of an analysis of resource demand by the early post-contact (1721) Cherokee population with spatially explicit estimates of production for five key resources: architectural land, agricultural land, firewood, hard mast, and white-tailed deer (Odocoileus virginianus). We combine a recent synthesis of village location and population, a map of recognized Cherokee territory, digital terrain data, estimates of per capita demand, and productive capacity for each resource. Average, high, and low demands were estimated for each resource and assigned based on a weighted function of terrain and distance from each village. We conclude that Cherokee demands for architectural and agricultural land, hard mast, and fuelwood were easily met within a short proximity to each town under all combinations of production and demand. These resources were likely not limiting, and were satisfied for the entire Cherokee population by less than 1% of the entire recognized Cherokee territory in 1721. These resources likely exceeded demand even when sources were restricted to the convex hull of the Cherokee territory, or to near stream, flat regions. Deer resources were likely harvested over a much larger area and to a much greater extent. Our best estimate of deer resource demand was 32% of annual sustainable production in the Cherokee territory, with from 16 to 48% of estimated sustainable production harvested for low and high demand estimates, respectively. Our estimates vary in response to uncertainties in deer production, harvest proportion, deer density, and sustainable harvest rates. Deer demand was substantially higher under all combinations of conditions than that available within the convex hull of Cherokee villages, indicating significant travel was needed to furnish deer requirements. Spatially explicit models that consider terrain- and distance-related tradeoffs suggest that Cherokee demand for deer drove harvest over areas consisting of over half the recognized Cherokee territory.  相似文献

This article reviews the state of the two security and defence institutions available to west Europeans: NATO and the EU's common European Security and Defence Policy (ESDP). In each case, the authors assess the political maturity and stability of the institution, and then ask what it can contribute in terms of coordinated military capability to west European's strategic readiness. NATO's Prague summit in November 2002 will address the thorny issue of the next tranche of post–Cold War enlargement. But beyond the predictable debate about which candidates to admit, and what should be offered to those unsuccessful in their bid, there will be a far more urgent and important agenda to be discussed at Prague—the military capabilities of the European allies. Given that ESDP is still far from achieving its capability goals, the authors argue that the time is right for European allies to begin thinking in terms of generating a composite, joint strike force which could be configured to be interoperable with US forces and which could salvage something useful from the disheartening lack of progress in developing a European military capability.  相似文献
