Twenty years ago the intellectual projects that have become known as critical geopolitics emerged at the end of the cold war as a series of critiques of geopolitical reasoning. Drawing heavily on Edward Said's formulations of Orientalism the critical analyses probed the dense cultural productions of danger, the rationalisations for intervention and the logics of “Western” foreign policies. The geographical specifications of the world in the political discourses used to justify numerous imperial actions, and the rationales for the provision of security came under sustained scrutiny. Now two decades later despite the supposed end of history and endless invocations of globalization, the themes of empire and Orientalism remain at the heart of the Western geopolitical imaginary, explicitly structuring how the security intellectuals of our time plan for war and justify the construction of their military machines. Given the continuing dangers of warfare in a biosphere that is being radically destabilized by the modes of economy and violence these geopolitical texts legitimize, the necessity for critique remains compelling. But given the proliferation of uses of the term critical geopolitics, and the numerous disciplinary concerns encompassed by it, perhaps the time has come to narrow its focus once again to its core themes which involve confronting and challenging the geographical reasoning used in the legitimizations of contemporary warfare.  相似文献

Well‐resourced and well‐connected individuals, or “policy entrepreneurs,” often play an important role in advocating and securing the adoption of policies. There is a striking lack of inquiry into the ways that social networks shape the ability of these actors to achieve their aims, including the ways in which network ties may channel policy conflict. To address these gaps, we analyze data from an original survey and an original database of policies to assess the success of policy entrepreneurs (PEs) active in a highly contentious arena: municipal policymaking concerning high‐volume hydraulic fracturing (HVHF) in New York. We use text‐mining to collect social network data from local newspaper archives, then use those data to construct municipal HVHF policy networks. Municipal anti‐HVHF PEs appear more successful when they operate in less cohesive networks, act as bridges to relative newcomers to the governance network, and have a larger number of network connections. Pro‐HVHF PEs appear more successful when they can forge high‐value connections to key decision makers. Policy entrepreneurs on both sides of the issue are more successful when they have a greater number of sympathetic coalition partners.  相似文献

Anthropologists require methods for accurately estimating stature and body mass from the human skeleton. Age-structured, generalized Least Squares (LS) regression formulas have been developed to predict stature from femoral length and to predict body mass in immature human remains using the width of the distal metaphysis, midshaft femoral geometry (J), and femoral head diameter. This paper tests the hypothesis that panel regression is an appropriate statistical method for regression modeling of longitudinal growth data, with longitudinal and cross-sectional effects on variance. Reference data were derived from the Denver Growth Study; panel regression was used to create one formula for estimating stature (for individuals 0.5–11.5 years old); two formulas for estimating body mass from the femur in infants and children (0.5–12.5 years old); and one formula for estimating body mass from the femoral head in older subadults (7–17.5 years old). The formulas were applied to an independent target sample of cadavers from Franklin County, Ohio and a large sample of immature individuals from diverse global populations. Results indicate panel regression formulas accurately estimate stature and body mass in immature skeletons, without reference to an independent estimate for age at death. Thus, using panel regression formulas to estimate stature and body mass in forensic and archaeological specimens may reduce second stage errors associated with inaccurate age estimates.  相似文献

Throughout the twentieth century doctors in most western countries strongly resisted government attempts to intervene in private medical markets. The support for privatisation that has developed during the current economic recession is welcomed therefore by the medical profession. In several countries campaigns have been staged for a full or partial return to market forces in the health care field. This article traces the course of one such push in Canada where doctors and other advocates of privatisation demanded a larger role for the private sector in the funding and management of Medicare, the national health insurance system. The policy outcome is contrary to the general privatising tendency in many countries: after a period of intense controversy the federal government passed legislation to preserve and strengthen the public aspects of the scheme. The normally powerful medical profession lost its campaign for an infusion of private funds into the health system and for the retention of the right of doctors to set their own fees. Consumer and other non‐producer groups, which have not traditionally played a central role in health policy, mobilised in defense of Medicare and were able to achieve most of their aims.  相似文献

Policy scholars have effectively leveraged policy process models, theories, and frameworks to respond to a variety of important environmental questions. For example, how do environmental issues arrive on the agendas of policymakers? What factors contribute to environmental policy change? What are the designs and effects of institutions (e.g., policies or cultural norms) on environmental governance? In this review, we survey the field of policy process scholarship, focusing on environmental governance, with three objectives. The first objective is to catalog the policy process models, theories, and frameworks most often featured in studies of environmental governance. The second is to capture the methodological choices commonly employed in the application of these models, theories, and frameworks in environmental domains. The third is to identify how these approaches deal with issues central to environmental governance research, including time, space, and policy scale. We aim to identify trends and strategies for integrating key considerations of scale into empirical policy process scholarship.  相似文献

This paper uses a case study of wetland regulation in the United States to develop elements of a theory about institutional stability and change in policy processes involving large public organizations. This theoretical approach draws on the Institutional Analysis and Development framework to understand events that are not well explained by other policy theories. Our approach accounts for the theoretically unexpected outcomes of the U.S. Supreme Court's ruling in Rapanos v. United States, which stood to change the way the U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency regulate the filling of wetlands. We propose a typology of institutional types that operate inside public organizations, and use process tracing to show how tacit institutions, those created informally within public organizations, can play key roles in determining the outcomes of policy processes. In the Rapanos case, informal coordination mechanisms enabled regulators and members of the regulated community to preserve substantially the pre‐ruling status quo. The key role of these microlevel interactions in shaping the macrolevel behaviors of public organizations underscores the importance of further research investigating how, in similar cases, different behavioral mechanisms interact in often complex and unexpected ways to determine the outcomes of policy processes.  相似文献
