    Examining public policy from a gendered intra-household perspective: changes in family-related policies in the UK, Australia and Germany since the mid-nineties

    Public policy can affect many different gender inequalities. However, relatively little attention has been paid to the effects of policy on gender inequalities within households. This paper analyses a range of family-related policy changes over the last fifteen years in Australia, Germany and the UK to compare their potential effects on intra-household gender inequalities. These include changes in parental leave policies, working time regulation, childcare support and financial support to families. Many of these changes are found to have contradictory effects on within household inequalities, mainly because those that improve women’s incomes in their current gender roles may also undermine incentives to challenge traditional gender roles. All three countries have implemented substantial reforms over the period considered. However, with labour market activation policies tending to favour an inherently unequal one-and-a-half earner household, the effects on inequalities within households did not meet increasingly egalitarian gender role attitudes

    Globin-based redox signaling

    In recent years, moderate levels of reactive oxygen species (ROS) have become recognized as signaling cues that participate at all levels of cellular organization. Globins, with their redox-active heme iron and ubiquitous presence, seem ideally suited to participate in ROS metabolism. Here we comment on our recent findings that show the participation of a globin, GLB-12, in a redox signaling pathway in Caenorhabditis elegans. We found that GLB-12 produces superoxide, a type of ROS, after which this is converted to what appears to be a hydrogen peroxide gradient over the plasma membrane by the activity of intracellular and extracellular superoxide dismutases. In the first part, we discuss in more detail the different regulatory mechanisms that increase the effectiveness of this redox signal. In the second part, we comment on how specific structural and biochemical properties allow this globin to perform redox reactions. Interestingly, these properties are also observed in 2 other C. elegans globins that appear to be involved in redox biology. We therefore hypothesize that globins involved in redox signaling display similar structural and biochemical characteristics and propose that a subgroup of globins can be added to the group of proteins that play a vital role in redox signaling

    Towards an Aesthetics of the (in)formel: Time, Space and the Dialectical Image in the Music of Varèse, Feldman and Xenakis

    This thesis addresses the issue of the modernist musical artwork, specifically in terms of the spatialization of musical time, in aesthetic and music-analytic terms. Firstly, it focuses on the notion of musique informelle as it was expounded in Adorno’s essay ‘Vers une musique informelle,’ (1961) and its place in Gianmario Borio’s elaboration of this in terms of an aesthetics of the informel. Secondly, it proposes a further expansion of these aesthetics via a double strategy: a comparative reading of Walter Benjamin’s critique of philosophies of time (including the work of Henri Bergson), language and objects, and furthermore a reconceptualization of both Adorno’s and Borio’s aesthetics in terms of a new theory of the object (as sound-object) in light of a new reading strategy. This reading is based on Walter Benjamin’s notion of the dialectical image, which proposes a new form of philosophical interpretation. The theorizations of the sound-object and the dialectical image furnish a basis for a re-conceptalization of the (in)formel, allowing for the interpretative reading of the music of three composers in particular: Edgard Varèse, Morton Feldman and Iannis Xenakis. Particularly, the study of a number of their works, including Intégrales (Varèse), On Time and the Instrumental Factor and Words and Music (Feldman), and Duel (Xenakis), reveals what Adorno terms their (truth) content, in their mediation of rationalization and intuition. Finally, it is argued that these modernist works can in turn bring new insights into Adorno’s aesthetics of the modernist work of art
