It has been claimed that transport policy in the UK, once a quiescent area, has been opened to battle between competing advocacy coalitions and that the late 1980s and early 1990s saw a policy paradigm shift. This article examines one detailed historical case study, the plans to complete an inner road in Norwich and the subsequent collapse of the scheme. The aim is firstly to examine the complex decision making processes and subsequent politics of this scheme and secondly to relate the local issue to the idea of a paradigm shift in national roads policy. The complexity of decision making in a multi-actored arena, where sovereignty is located locally but is circumscribed by central government 'guidelines', suggests that the assertions of those who argue in terms of a paradigm shift in policy may be exaggerated.  相似文献

In recent years much has been written on the communist successor parties. Although much of the existent work focuses on the electoral performance of these parties or has described, in great detail, the development of single parties, this paper evaluates the utility of theories of party identity change in application to the successor parties. As an initial exploration we investigate the successor parties' programs before and after the initial competitive parliamentary elections in Hungary (in 1990), Poland (in 1991) and Russia (in 1993) to determine the extent to which poor electoral performance in initial competitive elections compelled the successor parties to alter their political identities.  相似文献

Drawing on rational choice theory, this study considers how best to measureunemployment within the context of the unemployment–property crimerelationship. Specifically, we use ARIMA techniques to examine the relativeefficacy of using the conventional Bureau of Labor Statistics (BLS)unemployment rate and two alternative measures of the demand for labor aspredictors of monthly counts of U.S. property offenses for the years 1982through 1996. The bivariate time series analyses indicate that while theBLS unemployment rate exhibits null effects, the number of individualsunemployed for 15 weeks or more and the capacity utilization ratesignificantly affect the level of property crime. The implications ofthese results are discussed.  相似文献

Abstract. Drawing on the political theories of corporatism, neo–liberalism and pluralism, and on comparative empirical research in Brussels, Germany, Sweden and the UK, this article conceptualises the nature of Europeanised medicines regulation. It argues that a marketisation of regulation has been established in the European Union as a result of competition between national regulatory agencies for 'regulatory business' from the pharmaceutical industry. In the pharmaceuticals sector the Europeanised regulatory state is a product of three key factors: (a) the European Commission's commitment to an 'efficiency' regime which would meet the political objectives of a single European market and the commercial agendas of transnational pharmaceutical companies, (b) the endemic corporate bias associated with medicines regulation in the most influential member states, and (c) the considerable success of neo–liberal politics across a number of major member states, including Germany, Sweden and the United Kingdom.  相似文献

Youth living in impoverished urban neighborhoods are at risk for becoming hopeless about their future and engaging in violent behaviors. The current study seeks to examine the longitudinal relationship between social connections, hopelessness trajectories, and subsequent violent behavior across adolescence. Our sample included 723 (49% female) African American youth living in impoverished urban neighborhoods who participated in the Mobile Youth Survey from 1998 through 2006. Using general growth mixture modeling, we found two hopelessness trajectory classes for both boys and girls during middle adolescence: a consistently low hopelessness class and an increasingly hopeless class with quadratic change. In all classes, youth who reported stronger early adolescent connections to their mothers were less hopeless at age 13. The probability of later adolescent violence with a weapon was higher for boys and was associated with the increasingly hopeless class for both boys and girls. Implications for new avenues of research and design of hope-based prevention interventions will be discussed.  相似文献
