Technological Strengths in Mature Sectors--An Impediment or an Asset for Regional Economic Restructuring? The Case of Multimedia and Biotechnology in Baden-Wurttemberg

Baden-Württemberg's innovation system, which is characterised by a high degree of institutionalisation as well as a predominance of incremental innovations and medium technology finds itself in a profound process of transition. The paper discusses whether Baden-Württemberg's strength as an industrial district dominated by mature industries is an impediment or rather an asset with regard to developing new promising technological sectors in the region. The paper focuses on two newly emerging sectors: multimedia and biotechnology. Because of the strong orientation of actors in Baden-Württemberg to established companies in the core industries and the dominance of established organizational networks there is a lack of stimuli for developing new industries. Thus, institutional innovation and new networks are required to speed up the growth of the new industries. Baden-Württemberg can be expected to cope with the transition to the extent that it builds a close connection between its existing sectoral strengths and the new growth industries.     

Relationships between characteristics of teachers and teachers' assessments of sources of information

The Researchers' primary purpose was to explore relationships between (a) urban area secondary school teachers' assessments of thirty three sources of information apt to influence their practice and (b) specific characteristics of these teachers. A sample of 245 teachers, or 61% of the set contacted, participated. Qualitative and quantitative analyses of data offered by the respondents were carried out. Both predictable and perplexing outcomes of the data analyses were documented. The Researchers concluded: a) That demographic profiles of teachers can be discerned which are related to assessments of various information sources; and b) that teachers' needs for information can be linked to preferred sources of information. They were unable to explain why variables like years of teaching experience, sex, and age were related significantly to teachers' assessments of sources of information.     

European Law and International Regimes: The Features of Law Beyond the Nation State

Different forms of law are perceived of as possessing differing degrees of legal quality. A quality continuum suggests itself, running from 'high quality' national law, through to 'lesser quality' European law and to 'low quality' international law. This article seeks to explain the perceived differences in the quality of these laws with reference to legal theoretical perceptions of what it is that constitutes the law's quality. It argues that only a theory of law which identifies the core of the law's integrity as lying in its ability to act as a fulcrum between spheres of social and public discourse and the exercise of power can fully explain the divergence in legal quality between national, European and international law. With specific regard to the quality of European law, it concludes by arguing that it is weakened by its relative lack of social internalisation—in comparison with a higher degree of legal and political internalisation—within the European public.     

Konkordanztheorie und Abstimmungsdaten: eine explorative Aggregatsanalyse auf Bezirksebene

Bei Überprüfung der Konkordanztheorie für die Schweiz stellt sich immer wieder das Problem, wie sich die Konfliktlinien zwischen den Sprachgruppen, Konfessionen, sozialen Schichten und Stadt‐Land in der bundesstaatlichen Geschichte seit 1848 tatsächlich entwickelt haben. Es bleibt unklar, wie sich die Intensität dieser Konfliktlinien und das Ausmass an Konkordanz wechselseitig beeinflusst haben. Stimmt die Vermutung, dass die Konfliktlinien an Bedeutung verloren haben und dass die schweizerische Gesellschaft insgesamt homogener geworden ist? War Konkordanz in diesem Prozess eher die Ursache oder die Folge verminderter Konfliktintensität? Regionalisierte Daten der Volksabstimmungen bieten zusammen mit weiteren Quellen der amtlichen Statistik reiches Material, um die Bedeutung von Sprache, Konfession, sozialer Schichtung und Stadt‐Land in der bundesstaatlichen Geschichte zu bestimmen. In explorativer Weise werden in diesem Aufsatz 51 Abstimmungen in der Zeitspanne von 1992 bis 1997 auf der Basis von Aggregatdaten auf der Bezirksebene untersucht. Die Studie dient der Entwicklung eines geeigneten Modells, das in einer späteren Längsschnittanalyse auf alle eidgenössischen Abstimmungen angewendet werden soll.     

School vouchers and academic performance: results from three randomized field trials

This article examines the effects of school vouchers on student test scores in New York, New York, Dayton, Ohio, and Washington, DC. The evaluations in all three cities are designed as randomized field trials. The findings, therefore, are not confounded by the self‐selection problems that pervade most observational data. After 2 years, African Americans who switched from public to private school gained, relative to their public‐school peers, an average of 6.3 National Percentile Ranking points in the three cities on the Iowa Test of Basic Skills. The gains by city were 4.2 points in New York, 6.5 points in Dayton, and 9.2 points in Washington. Effects for African Americans are statistically significant in all three cities. In no city are statistically significant effects observed for other ethnic groups, after either 1 or 2 years. © 2002 by the Association for Policy Analysis and Management.
