    Notes: Abstract The cytosol and nuclear extract of gill tissue obtained from laboratory held Atlantic salmon,Salmo salar manifested saturable cortisol binding of high affinity and low capacity (cytosol: Ka = 0.198 ± 0.024 × 109/M, Nmax = 116.8 ± 20.8 fmol/mg protein; nuclear extract: Ka = 0.823 ± 0.057 × 107/M, Nmax = 1563 ± 330 fmol/mg protein; n = 4). The cytosol receptor activity displayed high steroid and tissue specificity and a single binding peak at 191,000 Da following gel permeation chromatography. Atlantic salmon exposed for 3 or 8 months to waters from the Medway River (pH about 5.1), the Westfield River (pH about 4.8) and calcium carbonate treated Westfield River (pH about 5.6) showed no gill cytosol receptor activity. Cortisol receptor activity in the gill nuclear extracts from fish in limed Westfield River water in December (3 months) was less than half the activity in the fish treated with Medway River water (p 〈 0.05) although the plasma cortisol values were not different. In May (8 months), the plasma cortisol of fish in limed water was almost twice that of the fish held in acid Westfield River water (p = 0.058).

    Description / Table of Contents: Synthesis of Stereoisomeric 3,4-Dihydrobilirubinic Acid Derivatives as Building Blocks for the Synthesis of Bile PigmentsBy reduction of 5′-carboxyneoxanthobilirubinic acid 3 with sodium amalgam in hot water the stereoisomeric 5′-carboxy-3,4-dihydrobilirubinic acids 9 and 15 are formed and from the isomer 4 the stereoisomers 10 and 16 can be obtained. The stereoisomers can be separated by preparative HPLC on reversed-phase silica gel. The unequivocal determination of the configuration was performed with the aldehydes 11, 12 and 17, 18.
    Notes: Durch Reduktion der 5′-Carboxyneoxanthobilirubinsäure 3 mit Natriumamalgam in heißem Wasser gewinnt man die stereoisomeren 5′-Carboxy-3,4-dihydroneobilirubinsäuren 9 und 15 und aus dem Isomeren 4 entsprechend die Stereoisomeren 10 und 16. Die Stereoisomeren lassen sich durch präparative HPLC an Reversed-Phase-Kieselgel voneinander trennen. Die eindeutige sterische Zuordnung erfolgt bei den Aldehyden 11, 12 und 17, 18.

    Description: Economic globalization, welfare state transformation as well as political and social change on national and supranational level impact on national labor markets in advanced societies in complex ways. From a gender perspective, these dynamics of change entail deregulation as well as re-regulation of employment systems and at the same time are triggered by shifts in gender relations. Addressing this complexity poses challenges to scholarly research comparing employment systems and systemizing cross-national variations of labor market regimes which tend to neglect gender relations as a relevant factor of change. This context sets the framework for our question on how ongoing changes in employment systems and in gender relations are taken up in recent scholarship. We focus on three approaches prominent in the mainstream scholarly debate which address the current state of employment systems in advanced economies in comparative perspective spanning from political economy to micro economics and economic sociology, namely the Varieties of Capitalism (VOC) approach (Hall/Soskice 2001), Marsden's micro-economic theory of employment systems (1999) and Fligstein's work 'The architecture of markets' (2001). The approaches differ in the assignment of agency (to firms, employees and the state) as well as in the assessment of the role of educational institutions for shaping employment systems. They thus dispose of different pitfalls and potentials for analyzing the gendered character of change of employment systems.
    Description: Unter dem Einfluss von Globalisierung, Wohlfahrtsstaatstransformation und politischen und gesellschaftlichen Umbrüchen sind nationale Arbeitsmärkte in fortgeschrittenen Marktökonomien erheblichen Veränderungen ausgesetzt. In geschlechtssensibler Perspektive wird deutlich, dass hier nicht nur Deregulierung von Beschäftigung sondern auch Re- Regulierung eine Rolle spielt, ebenso wie Arbeitsmarktdynamiken auch durch Veränderungen im Geschlechterverhältnis beeinflusst sind. Diese Komplexität des Wandels stellt eine Herausforderung für die vergleichende Arbeitsmarkt- und Wohlfahrtsstaatsforschung dar, in deren Typisierung von Arbeitsmarktregimes Geschlechterverhältnisse nur begrenzt Berücksichtigung finden. Vor diesem Hintergrund fragen wir, wie in einschlägigen neueren Ansätzen zur Analyse von Arbeitsmärkten Wandel von Beschäftigungssystemen und Geschlechterverhältnissen konzipiert wird. Im Mittelpunkt stehen drei prominente komparatistisch ausgerichtete Konzepte: der polit-ökonomische Ansatz ‚Varieties of Capitalism’ (Hall/Soskice 2001), die mikro-ökonomische Theorie von Beschäftigungssystemen von David Marsden (1999) und Neil Fligstein’s wirtschaftssoziologischer Ansatz ‚The architecture of markets’ (2001). Wie die Ergebnisse zeigen, unterscheiden sich die Ansätze in der Identifikation von relevanten Akteuren (Betriebe, Beschäftigte, Staat) ebenso wie in der Rolle, die Ausbildungsinstitutionen für die Strukturierung von Arbeitsmärkten zugeschrieben wird. Damit ergeben sich für die Analyse von geschlechtsspezifischen Aspekten von Beschäftigung unterschiedliche blinde Flecken und Erkenntnispotentiale.

    Description: Die Kulturberufe gehören zu den seit Jahren expandierenden Wissensberufen und nehmen im bundesdeutschen Erwerbssystem in verschiedener Hinsicht eine Sonderstellung ein. So werden sie häufig in der Form des 'Alleindienstleisters' ausgeübt und weisen hohe Frauenanteile und Akademisierungsgrade auf. Von daher sind sie für die Frage nach 'zukunftsfähigen' Formen von Erwerbsarbeit für beide Geschlechter besonders interessant. Das Papier stellt zunächst in erwerbssoziologischer Perspektive Charakteristika der Kulturberufe in Abgrenzung zu den beiden dominanten Erwerbstypen - den 'klassischen' Professionen und dem 'verberuflichten Arbeitnehmer' - wie auch zu den traditionell feminisierten sog. Semi-Professionen dar. Gefragt wird weiter nach theoretischen Erklärungsansätzen für diesen vergleichsweise jungen Erwerbstypus. Dabei erscheint weniger die Professionstheorie als vielmehr das arbeitssoziologische Konzept des 'Arbeitskraftunternehmers' weiterführend, insofern es in subjektorientierter Perspektive Grenzverschiebungen zwischen Arbeit und Leben Rechnung trägt. In einem weiteren Schritt werden erste empirische Ergebnisse zur sozialstrukturellen Verfassung der Kulturberufe präsentiert, die ambivalente Deutungen nahe legen. So scheint einerseits Erwerbsarbeit in den Kulturberufen weniger durch Geschlechterstereotype geprägt zu sein als in den erwähnten anderen Erwerbstypen. Andererseits jedoch deuten die zu vermutenden Arrangements von Arbeit und Leben nicht unbedingt auf egalitäre Muster hin. Abschließend wird weiterer Forschungsbedarf thematisiert.
    Description: Cultural professions belong to the expanding knowledge-based occupations and for several reasons take a special position in the German employment system. Thus they are often practised in single person self-employment, and, moreover, show an increasingly academic work force and high shares of female professionals. Hence they seem to be promising with respect to 'sustainable' forms of employment for both genders. In a sociological perspective, this paper firstly describes the characteristics of cultural professions in contrast to the two at least in German predominating types of work - the 'classical' professions and the 'standard employment relationship' - as well as the traditionally feminized so-called 'semi-professions'. Secondly, we discuss explanatory theoretical concepts for this comparatively young type of work. Here the theories of professions seem to be less fruitful than the quite recent concept of 'entrepreneur of one's own labour force' ('Arbeitskraftunternehmer') that has primarily been developed by two German industrial sociologists (Voß/Pongratz 1998). This theoretical model pursues a perspective oriented by the individual subject which implies taking account of the shifting borders between work and life. Moreover, first empirical results are presented with regard to the social-structural constitution of cultural professions which suggest ambiguous interpretations. On the one hand, work in cultural occupations seems to be less gender-segregated than the other mentioned types of employment. On the other hand, the expected work and life arrangements do not necessarily indicate egalitarian patterns. Finally, the needs of further research are expressed.
