Die Grippe‐Pandemie 1918–20 in der medizinischen Debatte

The Influenza Pandemic of 1918–20 in medical debate. The history of the so called Spanish Influenza 1918–1920 is summarized especially in regard to the developments in medical debate. In Germany, Richard Pfeiffer, who had discovered Haemophilus influenzae after the previous pandemic 1890 / 91, managed it to defend his thesis that his “bacillus” was the causative agent of the flu, by modifying his theory moderately. The Early Virology of influenza in postwar times was still fixed to bacteriology and did not yet have the force of school‐building. Aggressive therapy, e.g. with derivatives of chinine, were used in a concept of polypragmasy. The connection between influenza in animals and influenza in mankind was unknown or of no major interest till the rise of virology as an academic discipline in the 1950s. Since the outbreak of avian influenza in Asia 1997 virological archaeology is challenged to fill the historical part in the attempt to fight the threat of the highly pathogenic bird flu. In the beginning of the “short 20. century” politicians and doctors had no interest to build a “monument” of influenza. Today, virological reductionism does not have the power to (re‐)construct such a monument.     

European Corridors as Carriers of Dynamic Agglomeration Externalities?

Transport corridors are viewed as a promising way forward in European Union (EU) transport policy, assumed to contribute positively to regional economic development. However, the validity of this assumption is not evident. The aim of this paper is to empirically test whether agglomeration economies in European transport corridor regions are positively related to indicators of regional economic development compared to regions outside the scope of corridors. The results build on the notion that the type of agglomeration economy in combination with the structure of the economy matters for prospects of structural economic growth in different regions. In this way, the analysis not only contributes to enhancing the empirical scrutiny of the corridor concept in EU transport policy, but also provides new insights into how corridors contribute to regional economic growth. We find only limited evidence for a corridor effect across European regions on productivity and employment growth externalities. Instead, we find a large degree of spatial heterogeneity interacting with corridors—a heterogeneity that has been little recognized in EU policies. We suggest that recent attention to place-based development strategies may accord well with the kinds of agglomeration effects related to corridor development observed in this study.     

School Vouchers and Student Attainment: Evidence from a State‐Mandated Study of Milwaukee's Parental Choice Program

In this article we examine educational attainment levels for students in Milwaukee's citywide voucher program and a comparable group of public school students. Using unique data collected as part of a state‐mandated evaluation of the program, we consider high school graduation and enrollment in postsecondary institutions for students initially exposed to voucher schools and those in public schools at the same time. We show that exposure to voucher schools was related to graduation and, in particular, to enrollment and persistence in a 4‐year college. These differences are apparent despite controls for student neighborhoods, demographics, early‐career test scores and—for a subsample of survey respondents—controls for parental education, income, religious behavior, and marital status. We conclude by stressing the implications for future scholarship and policy, including the importance of attainment outcomes in educational research.     

Innovative transnationale Projekte Ein Überblick

Abstrakt Transnationale Zusammenarbeit ist ein wichtiges Mittel, den Prozess des Zusammenwachsens in Europa zu unterstützen und um Nutzen für den wirtschaftlichen und sozialen Fortschritt zu ziehen. Dies gilt umso mehr angesichts der in jüngster Zeit st?rkeren Betonung nationaler Politikans?tze. Programme und Projekte der transnationalen Zusammenarbeit (INTERREG III B) versuchen, beispielhafte L?sungen für Herausforderungen der europ?ischen Raumentwicklung zu erarbeiten und eine europaweite Anwendung entwickelter Modelle zu f?rdern. Das geographische Berufsprofil eignet sich in besonderer Weise, daran mitzuwirken. Gleichzeitig tr?gt die projektkonkrete Arbeit zu einer Sch?rfung dieses Profils bei und verschafft den Beteiligten vielf?ltige Kompetenzgewinne.
