Zum Zusammenhang von Geschlechterungleichheiten in Bildung, Beruf und Karriere : ein Ausblick

Ziel der folgenden Ausführungen im abschliessenden Teil dieses Sammelbands zur Entwicklung und Genese von geschlechtsspezifischen Bildungsungleichheiten ist es, den Blick zu öffnen in Richtung Berufsleben. Wie sind die verbesserten Bildungsmöglichkeiten von Frauen zu interpretieren? Ist es in den letzten Jahrzehnten gelungen, eines der grundlegendsten gesellschaftlichen Ungleichheitsverhältnisse zu beseitigen? Oder beginnt sich dieses sogar zu verkehren in eine gesellschaftliche Benachteiligung der Männer? Wir gehen bei unseren Überlegungen von der These aus, dass ein Abbau von Benachteiligungen der Frauen im Bildungssystem für sich genommen noch wenig aussagekräftig ist, wenn wir uns mit der klassischen soziologischen Frage der Persistenz bzw. des Wandels von gesellschaftlichen Ungleichheiten befassen wollen. Erst wenn die ganze Verknüpfung von Bildung und gesellschaftlicher Ungleichheit in den Blick genommen wird und sich dabei zeigt, dass Frauen ihre Bildungsgewinne auch in entsprechende Chancen im Beschäftigungssystem umsetzen können, sind ihre verbesserten Bildungschancen ein Gewinn für die Individuen und ein Fortschritt für die Gesellschaft – und erst dann könnten mögliche Bildungsvorteile von Frauen, wie sie in den vorliegenden Aufsätzen z.T. diagnostiziert werden, gar als neue gesellschaftliche Benachteiligungen von Männern skandalisiert werden

Translations of new public management: a decentred approach to school governance in four OECD countries

Despite the prevalence of corporate and performative models of school governance within and across different education systems, there are various cases of uneven, hybrid expressions of New Public Management (NPM) that reveal the contingency of global patterns of rule. Adopting a ‘decentred approach’ to governance (Bevir, M. 2010. “Rethinking Governmentality: Towards Genealogies of Governance.” European Journal of Social Theory 13 (4): 423–441), this paper compares the development of NPM in four OECD countries: Australia, England, Spain, and Switzerland. A focus of the paper is how certain policy instruments are created and sustained within highly differentiated geo-political settings and through different multi-scalar actors and authorities yet modified to reflect established traditions and practices

Inhibition of ongoing allergic reactions using a novel anti-IgE DARPin-Fc fusion protein

Aggregation of the high-affinity IgE receptor (FcεRI) with the low-affinity IgG receptor (FcγRIIb) on basophils or mast cells has been shown to inhibit allergen-induced cell degranulation. Molecules cross-linking these two receptors might therefore be of interest for the treatment of allergic disorders. Here, we demonstrate the generation of a novel bispecific fusion protein efficiently aggregating FcεRI-bound IgE with FcγRIIb on the surface of basophils to prevent pro-inflammatory mediator release

Supplementary Material for: Improved FcγRIIb Targeting Functionally Translates into Enhanced Inhibition of Basophil Activation

<b><i>Background:</i></b> Mast cells and basophils express the high-affinity IgE receptor, FcεRI, as well as the low-affinity IgG receptor, FcγRIIb. While FcεRI is responsible for IgE-dependent degranulation upon coaggregation with allergens, FcγRIIb has been shown to downregulate degranulation through cross-linking with FcεRI. A previously developed fusion protein consisting of an anti-IgE DARPin linked to the human IgG₁-Fc part (DE53-Fc) has been shown to simultaneously target FcεRI and FcγRIIb with low affinity and to thereby prevent basophil activation. The affinity of a ligand for its receptor is known to be critical for the functional consequences of the binding. So we generated two mutated DE53-Fc molecules with either an improved (DE53-Fc mut+) or a reduced (DE53-Fc mut-) binding to FcγRIIb and assessed their potential to inhibit IgE-dependent basophil activation. <b><i>Methods:</i></b> DE53-Fc was modified by introducing single site-directed point mutations in the Fc part. The mutated constructs were used to assess kinetic parameters as well as the inhibitory capacity on basophil activation and the production of leukotriene C₄ (LTC₄) and IL-13. <b><i>Results:</i></b> DE53-Fc mut+ showed increased affinity for FcγRIIb as well as an enhanced potential to inhibit IgG₁ binding to FcγRIIb, resulting in improved efficacy in functional assays. Furthermore, DE53-Fc mut+ decreased de novo-synthesized LTC₄ as well as the cytokine IL-13, suggesting that it might be an inhibitor of the allergic late-phase reaction. <b><i>Conclusion: </i></b>Our data suggest that improved binding to FcγRIIb at constant low-affinity binding to IgE leads to more efficient coaggregation of FcεRI-FcγRIIb and results in the enhanced inhibition of basophil activation

Innate immunity restricts Citrobacter rodentium A/E pathogenesis initiation to an early window of opportunity

Citrobacter rodentium infection is a mouse model for the important human diarrheal infection caused by enteropathogenic E. coli (EPEC). The pathogenesis of both species is very similar and depends on their unique ability to form intimately epithelium-adherent microcolonies, also known as “attachment/effacement” (A/E) lesions. These microcolonies must be dynamic and able to self-renew by continuous re-infection of the rapidly regenerating epithelium. It is unknown whether sustained epithelial A/E lesion pathogenesis is achieved through re-infection by planktonic bacteria from the luminal compartment or local spread of sessile bacteria without a planktonic phase. Focusing on the earliest events as C. rodentium becomes established, we show here that all colonic epithelial A/E microcolonies are clonal bacterial populations, and thus depend on local clonal growth to persist. In wild-type mice, microcolonies are established exclusively within the first 18 hours of infection. These early events shape the ongoing intestinal geography and severity of infection despite the continuous presence of phenotypically virulent luminal bacteria. Mechanistically, induced resistance to A/E lesion de-novo formation is mediated by TLR-MyD88/Trif-dependent signaling and is induced specifically by virulent C. rodentium in a virulence gene-dependent manner. Our data demonstrate that the establishment phase of C. rodentium pathogenesis in vivo is restricted to a very short window of opportunity that determines both disease geography and severity.ISSN:1553-7374ISSN:1553-736

Self- and peer-rated character strengths: How do they relate to satisfaction with life and orientations to happiness?

This paper addresses the question as to whether previously reported findings on a positive relation between character strengths, satisfaction with life, and orientations to happiness (OTH) can be replicated for peer ratings of character strengths. A sample of 334 Swiss adults completed questionnaires and collected informant ratings by 634 peers. Selfand peer ratings converged well and suggest that, primarily: the strengths of hope, zest, and curiosity – but also gratitude and love – play key roles in the interplay of strengths and satisfaction with life. Peer ratings of strengths also related positively with the endorsement of a pleasurable, engaged, and meaningful life. Further analyses show that the OTH predict satisfaction with life beyond self- and peer-rated character strengths. There, the engaged life (i.e. endorsement of flow) was most relevant. This study supports earlier findings that argue for an important role of character strengths when describing the well-being of a person
