Worlds come apart: Systems theory versus critical theory. Drama in the history of sociology in the twentieth century

This article places an episode in the history of sociological theory into intellectual history in the twentieth century. The perspective is chronological as well as contextual. The themes are two theoretical approaches, both embedded in both American and German history, Parsonian Systems Theory and “Frankfurt School” Critical Theory. The chronology shown spanned mainly from the 1940s to the 1960s. The context of the two theories is a period that is crucial in twentieth century history. The protagonists of the two approaches were, in the 1940s, Americans and Germans exiled in the United States. In the 1950s, both approaches were affected by McCarthyism in different ways. The 1960s, however, were the culmination. The dynamics of the two approaches led into a schism which came into the open on the occasion of the 1964 German Sociology Conference in Heidelberg celebrating Max Weber. The article shows the stages in the evolution of the schism, emulating three acts in a drama. The final split was over whether Weber or Marx should be the classic whose oeuvre was to influence sociological thinking today. My aim is to exemplify how these two authoritative approaches in sociological theory, far from escaping the vagaries and vicissitudes of their times, were embedded in twentieth-century history.     

Commercial discourses,gentrification and citizens’ protest: The linguistic landscape of Prenzlauer Berg,Berlin1

Since reunification in 1990, Prenzlauer Berg, located in the former East Berlin, has turned from a cheap and neglected area into a popular middle‐class neighbourhood. The area's new character is reflected in its linguistic landscape. These days the signs of posh shops and trendy bars adorn its streets. But alternative views are noticeable too. Graffiti is present even on the most expensively refurbished buildings and residents put up slogans to protest against their flats being refurbished and sold to new owners. This case study of the changing graphic environment of Prenzlauer Berg shows that, despite the strong influence of commercial discourses, the public space remains an area of contestation between civil society, private businesses and the state. The particular approach to linguistic landscape I developed combines textual and visual analysis with interviews with sign producers. This has enabled me to show how the linguistic landscape both reflects as well as shapes social change and urban development in Berlin since reunification. Seit der Wende ist der Prenzlauer Berg, zu DDR Zeiten vernachlässigt und heruntergekommen, zu einem der beliebtesten Stadtteile des neuen Berlins geworden. Der neue Charakter des Kiez, sichtbar an seinen renovierten Häusern und steigenden Mietpreisen, lässt sich auch anhand seiner sprachlichen Landschaft (linguistic landscape) erkennen. Heutzutage bestimmen die aufwendig gestalteten Schilder teurer Geschäfter und schicker Bars Prenzlauer Bergs Strassenbild. Es gibt aber auch andere Stimmen. Bewohner von Häusern, die an Investoren verkauft wurden und denen nun gesteigerte Mieten drohen, protestieren mit Plakaten gegen die Politik der Ankäufer. Fast keine der neu gestrichenen Fassaden ist frei von Graffiti und überall findet man Poster, die zu Demonstrationen und Unterschriftenaktionen aufforden. Ausgehend von Fotografien und Interviews mit den Autoren von Schildern, Plakaten und Transparenten zeigt der vorliegende Artikel, dass der öffentliche Raum – die Strasse – trotz der Dominanz kommerziellen Diskurse, ein Bereich bleibt, in dem Staat, private Inverstoren und bürgerliche Gesellschaft aufeinander treffen und ihre – oftmals im Konflikt zueinander stehenden – Meinungen zum Ausdruck bringen.

Evidence-based practice: a critical reflection

This article employs the process of critical reflection to uncover and challenge the hegemonic assumptions of evidence-based practice (EBP). The critical reflection process results in a re-conceptualisation of best practices that, while still honouring empirical research, is less hierarchical and more inclusive of a broad spectrum of interests than traditional EBP. Multidimensional Evidence-Based Practice (MEBP) validates consumer wisdom, professional experience, and qualitative research as equal partners to quantitative research in determining current state-of-the art best practices. Furthermore, MEBP incorporates a value-critical analysis of those best practices that can lead to improvements and innovations, so that ‘best practices’ becomes a dynamic rather than a static construct.     

The Volatility of Realized Volatility

In recent years, with the availability of high-frequency financial market data modeling realized volatility has become a new and innovative research direction. The construction of “observable” or realized volatility series from intra-day transaction data and the use of standard time-series techniques has lead to promising strategies for modeling and predicting (daily) volatility. In this article, we show that the residuals of commonly used time-series models for realized volatility and logarithmic realized variance exhibit non-Gaussianity and volatility clustering. We propose extensions to explicitly account for these properties and assess their relevance for modeling and forecasting realized volatility. In an empirical application for S&P 500 index futures we show that allowing for time-varying volatility of realized volatility and logarithmic realized variance substantially improves the fit as well as predictive performance. Furthermore, the distributional assumption for residuals plays a crucial role in density forecasting.     

Scholarship,not scandal

This short article pleads for research rather than rumor regarding Parsons' alleged role regarding the admittance to United States of an ex-Soviet citizen in 1948 or 1949. Some evidence on background issues that could be found among the Parsons papers at Harvard University Archives is being presented verbatim. I argue that the point is to refrain from fabrications.     

Arbeitsmarktsegregation und Einkommen

What mechanisms link horizontal labour market segregation and the gender gap in wages? One explanation is based on the cultural devaluation of typically ‘female’ skills and work contents which are held responsible for lower earnings in these occupations. In the present study the idea of devaluation of ‘female’ work is contrasted with other possible explanations such as occupational differences in specialized human capital requirements or unpleasant work conditions. Based on a large sample of employed persons in Germany (IAB-Beschaeftigtenstichprobe 1975–1995) and on a survey on work conditions (BIBB/IAB-Erhebung 1991/92), the influence of ‘female’ work contents and other occupational variables on individual earnings is modeled for East and West Germany separately. The results of multilevel analyses accounting for the embeddedness of individuals in occupations and industries show that some ‘female’ work contents — typing, cleaning and selling — decrease income, and thus are culturally devalued. In contrast, occupational differences in specialized human capital requirements and work conditions do seemingly not affect individual wages. In East Germany the results in regard of devaluation are less pronounced. In both parts of the country there is an unabatedly strong effect of individual sex on earnings which cannot be explained by the introduced occupational characteristics.
