This article focuses on the Progressive Conservative (PC) partyof Canada and contrasts the orientations of four different setsof PC party workers: those who are active in the provincialarena in Nova Scotia and in Alberta, as well as those who areactive in the national arena from the same two provinces. Thedata reveal that federalism has had a disaggregative effecton Canadian political party ideology. Not only is the cleavagebetween activists in different orders of government consistentlylarge; it also generally exceeds that which exists between activistsin different provinces. 相似文献

In a second test of an arthropod saturation hypothesis, we analyzed if the on-campus Anthropology Research Facility (ARF) at the University of Tennessee, Knoxville, with its 20+ yr history of carcass enrichment, is comparable to non-enriched sites in community structure of predatory and parasitic arthropods that prey upon the sarcosaprophagous fauna. Over a 12-day period in June 1998, using pitfall traps and sweep nets, 10,065 predaceous, parasitic, and hematophagous (blood-feeding) arthropods were collected from freshly euthanized pigs (Sus scrofa L.) placed at ARF and at three surrounding sites various distances away (S2-S4). The community structure of these organisms was comparable in most paired-site tests with respect to species composition, colonization rates, and evenness of pitfall-trap abundances on a per carcass basis. Site differences were found in rarefaction tests of both sweep-net and pitfall-trap taxa and in tests of taxonomic evenness and ranked abundances of sweep-net samples. Despite these differences, no evidence was found that the predatory/parasitic fauna at ARF was impoverished with fewer but larger populations as a result of carcass enrichment. Comparison of the sarcosaprophagous and predatory/parasitic faunas revealed a tighter (and more predictable) linkage between carrion feeders (sarcosaprovores) and their carrion than between carrion feeders and their natural enemies (predators and parasitoids), leading us to conclude that ARF is more representative of surrounding sites with respect to the sarcosaprovore component than to the predatory/parasitic component within the larger carrion-arthropod community. 相似文献

Infectious microorganisms are important to multiple communities engaged in biodefense and biosecurity, including the agencies responsible for health, defense, law enforcement, agriculture, and drug and food safety. Many agencies have created lists of high priority infectious microorganisms to prioritize research efforts or to formally control the possession and distribution of specific organisms or toxins. However, the biological classification of infectious microorganisms is often complex and ambiguous, leading to uncertainty and confusion for scientists involved in biosecurity work. To address this problem, we created a database, known as the Microbial Rosetta Stone, which resolves many of these ambiguities and includes links to additional information on the microbes, such as gene sequence data and scientific literature. Here we discuss the efforts to coordinate organism names from pathogen lists from various governmental agencies according to biological relatedness and show the overlap of high-priority organisms from multiple agencies. To our knowledge, this is the first comprehensive coordination of pathogens, synonyms, and correct taxonomic names. The organized tables and visual aids are freely available at http://www.microbialrosettastone.com. This website provides a single location where access to information on a broad range of disease-causing organisms and toxins is available to members of the biosecurity community. 相似文献

On the heels of widespread patient protection legislation in the states, the managed care industry abandoned or greatly scaled back the core elements of gate-keeping, utilization management, and financial incentives, which are the very targets of this legislation. This article explores whether, and to what extent, the industry's abrupt change in course can be attributed to these laws. Based on extensive interviews with key informants in six representative states, the article concludes that these laws were not the primary driver of changes in managed care practices. However, patient protection laws interacted with other social and market forces, through complex forms of feedback and reinforcement, to bring about more thoroughgoing change than would have otherwise occurred. 相似文献

Abstract: In Australia, current policy making is characterized by immobilism, drift and "pluralistic stagnation". The problem is not lack of technical expertise, but the mobilization of political consent in a polity in which pressure groups have proliferated. In the post-war period, the welfare state/managed economy has transformed the role of government and the potential power of pressure groups. New networks of interdependency have developed. Some of the principal groups are beneficiaries of redistributive programs, producer groups, state and local government agencies and professionals in government. Their potential power has been made actual by a new participative ethic. The post-materialist values of which this is part also result in the growth of groups focusing on quality of life and moral issues. In this context the political parties are losing their central place in the polity and the centralized organs of executive government appear over-secretive and aloof. Reforms are needed to realign institutions with the new cultural and structural realities. Broader interest group involvement is needed. Parliament, through a committee system, could play a major role and its historical function as custodian of the public interest should be revived. Departments must find new ways to involve more groups in policy formulation and implementation. Information must be shared more widely and policy analysts and advisors should work more closely with groups in defining issues, negotiating alternatives and encouraging the development of supportive coalitions. New "intelligence" and "outreach" functions within the public service are required, and the existing approaches of policy units and research bureaux should be remodelled. 相似文献

Der Beitrag geht der Frage nach, wie national unterschiedliche politökonomische Institutionen die Leistungskraft entwickelter Marktwirtschaften beeinflussen und ob institutionelle Komplementaritäten in der Makroökonomie existieren. Der Ansatz der ?Spielarten des Kapitalismus“ behauptet, dass es diese Komplementaritäten gibt und sich die Länder entsprechend dem in den ökonomischen Sphären vorherrschenden Modus der Koordination in klare Gruppen unterscheiden lassen. In dem Artikel werden die Kernaussagen des Ansatzes einer Reihe von empirischen Tests unterzogen, die auf einer zusammenfassenden Analyse einer Reihe von Fallbeispielen beruht, Die empirischen Ergebnisse bestätigen die Annahmen in überzeugender Weise. Dieliberalen undkoordinierten Marktwirtschaften variieren systematisch entsprechend dem relativen Verhältnis zwischen marktförmiger und strategischer Koordination. Institutionelle Komplementaritäten finden sich in beiden Typen, und sie bringen gesamtwirtschaftliche Leistungszuwächse hervor. Abschließend werden die Muster des institutionellen Wandels in den entwickelten politischen Ökonomien analysiert und einige politische Implikationen der Befunde diskutiert. 相似文献
