The barriers to terminating federal research and development vary with the type of program (manpower resource creation, basic or applied research, hardware development) and the functional sector in which it is lodged (defense or civilian). Each has a public/private constituency of sponsors and performers. Some constituencies are much more potent than others. Hence, to kill an R&D program, one must weaken the constituency behind it. Useful strategies for would-be terminators include decremental funding and the amalgamation of competing R&D programs within the same agency.  相似文献

While its economic dynamism stimulates continued growth in Asia, China's increasing demand for energy is creating intense competition, particularly with Japan, over international sources of supply. Domestic fields have generally been disappointing, as have efforts to pipe gas from Central Asia and Russia to the east coast. Consequently, China is not only paying greater attention to potential petroleum resources in the East and South China Seas, but also considering the vulnerability of its sea-lanes to the Middle East and beyond. Its need to diversify has promoted closer relations with Central Asia, the Middle East, and the oil producing countries of Africa and Latin America, but the jury is out on whether China's concerns for secure energy supply will lead to international cooperation against terrorism or fuel the already heated competition for oil and gas. As China continues to assure its future energy security in Asia and many areas of the world, sustained bilateral and multilateral diplomacy to reconcile disputes and avoid conflict will become more important than ever.  相似文献

Virtually no one in the United States raised objections to the 1964 military takeover of the Brazilian civilian government. In the early 1970s, however, the Brazilian regime had become associated with torture and the arbitrary rule of law. By the end of that decade, compliance with human rights standards had developed into a yardstick for measuring U.S. foreign policy initiatives in Latin America. This paper argues that between 1969 and 1974, a small group of dedicated church activists, exiled Brazilians, and academics introduced the issue of human rights in Latin America into the U.S. national body politic. A network of concerned activists fashioned a systematic campaign to educate journalists, government officials, and the public about the abuses taking place under the generals' rule. Their activities helped isolate the military regime and laid the groundwork for a broader solidarity movement with Latin American popular struggles in the late 1970s and 1980s.  相似文献

Over the years, the public administration literature has generated many different strands in the definition and conceptualization of citizenship. In theory and in practice, our understanding of what it means to be a citizen is in danger of being muddled amid the diversity of perspectives and the epistemological confusion generated in the contemporary discourse on the subject. My aim in this article is to clarify and elaborate a common thread that runs through our contemporary understanding of citizenship and to advance the general thesis that our brand of theorizing reflects an earlier tradition that embodies the conservative ethos of Aristotelian republicanism. Can such a tradition survive in modern American society?  相似文献

This article discusses the incremental but increasingly assertive efforts by federal policy makers toward encouraging deregulation of the electric utility industry. Focusing on the efforts of the Federal Energy Regulatory Commission (FERC), we conclude that the federal government is involved in a sort of two‐sided experiment. On the one hand, efforts to deregulate the electric power industry attempt to establish a competitive market pose the question: Can government provide rational guidance in the formation of markets in a complex industry? On the other hand, it asks whether the democratic process can permit agencies such as FERC to impose and implement an economically rational design on a self‐interested pubic that is mostly interested in cheap, reliable power. In a sense, FERC is auditioning for a new role for regulatory agencies—as designers and overseers of markets. This is a dramatic shift from the traditional role of “regulator as policeman.” Whether regulators are up to the task remains to be seen.  相似文献

Current approaches examining the effect of institutions on policy processes have difficulty in explaining the results of the legislative process of codecision between the European Parliament and Council within the European Union. The formal Treaty changes that gave rise to codecision have, in turn, given rise to a plethora of informal institutions, in a process that is difficult to understand using dominant modes of analysis. This article provides a framework for analyzing the relationship between formal and informal institutions, showing how the two may be recursively related. Formal institutional change at a particular moment in time may give rise to informal institutions, which may, in turn, affect the negotiation of future formal institutions. The article applies this framework to the codecision process, showing how the codecision procedure has led to the creation of informal institutions and modes of decision-making, which have affected subsequent Treaty negotiations. Through strategic use of the relationship between formal and informal institutions, the European Parliament has been successful in advancing its interests over time and increasing its role in the legislative process.  相似文献

Sizable economic consequences may resultfrom listing under the Endangered SpeciesAct (ESA). Potentially adversely affectedparties will attempt to use the politicalprocess to protect their interests. Thequestion is, “are listing determinationssubject to political manipulation?” Inthis paper, we explore empirically thepossibility that implementation of the ESAis determined, in part, by politicalconsiderations. Specifically, weinvestigate whether states with strongcongressional representation are able touse their political muscle to reduce thenumber of listings in their states, ascompared to states with weak congressionalrepresentation. Controlling for otherfactors, we find that states with greaterrepresentation on the U.S. Fish andWildlife Service’s budgetary oversightsubcommittee in the U.S. House ofRepresentatives have significantly fewerESA listings than states with weakerrepresentation on that subcommittee.  相似文献
