An Infrastructure for acquiring high quality semantic metadata

Because metadata that underlies semantic web applications is gathered from distributed and heterogeneous data sources, it is important to ensure its quality (i.e., reduce duplicates, spelling errors, ambiguities). However, current infrastructures that acquire and integrate semantic data have only marginally addressed the issue of metadata quality. In this paper we present our metadata acquisition infrastructure, ASDI, which pays special attention to ensuring that high quality metadata is derived. Central to the architecture of ASDI is a erification engine that relies on several semantic web tools to check the quality of the derived data. We tested our prototype in the context of building a semantic web portal for our lab, KMi. An experimental evaluation omparing the automatically extracted data against manual annotations indicates that the verification engine enhances the quality of the extracted semantic metadata

Role of Receptor-Interacting Protein 140 in human fat cells

<p>Abstract</p> <p>Background</p> <p>Mice lacking <it>Receptor-interacting protein 140 (RIP140) </it>have reduced body fat which at least partly is mediated through increased lipid and glucose metabolism in adipose tissue. In humans, <it>RIP140 </it>is lower expressed in visceral white adipose tissue (WAT) of obese versus lean subjects. We investigated the role of <it>RIP140 </it>in human subcutaneous WAT, which is the major fat depot of the body.</p> <p>Methods</p> <p>Messenger RNA levels of <it>RIP140 </it>were measured in samples of subcutaneous WAT from women with a wide variation in BMI and in different human WAT preparations. <it>RIP140 </it>mRNA was knocked down with siRNA in <it>in vitro </it>differentiated adipocytes and the impact on glucose transport and mRNA levels of target genes determined.</p> <p>Results</p> <p><it>RIP140 </it>mRNA levels in subcutaneous WAT were decreased among obese compared to lean women and increased by weight-loss, but did not associate with mitochondrial DNA copy number. <it>RIP140 </it>expression increased during adipocyte differentiation <it>in vitro </it>and was higher in isolated adipocytes compared to corresponding pieces of WAT. Knock down of <it>RIP140 </it>increased basal glucose transport and mRNA levels of <it>glucose transporter 4 </it>and <it>uncoupling protein-1</it>.</p> <p>Conclusions</p> <p>Human <it>RIP140 </it>inhibits glucose uptake and the expression of genes promoting energy expenditure in the same fashion as the murine orthologue. Increased levels of human <it>RIP140 </it>in subcutaneous WAT of lean subjects may contribute to economize on energy stores. By contrast, the function and expression pattern does not support that <it>RIP140 </it>regulate human obesity.</p

Social Change and Betty Friedan's The Feminine Mystique: A Study of the Charismatic Author-Leader

In this thesis I explore the significance of the publication of Betty Friedan's The Feminine Mystique (1963) to the emergence of the second wave Women's Liberation Movement in the US in the late 1960s. To this end, I deploy key concepts provided through social movement theory (eg collective identity, collective action frames, social problem construction). I also incorporate Max Weber and Antonio Gramsci's insights on the indispensable role played by leaders who demonstrate a clear and effective political will. Weber's three part model of pure charisma is used as a general template for understanding the impact of Friedan's text. I critique aspects of Weber's theory of charisma, in particular his failure to appreciate that the written word can mark the initial emergence phase of charisma rather than its routinisation. I augment Weber's insights on charismatic leadership by attending to Gramsci's emphasis on the necessity of winning the 'war of ideas' that must be waged at the level of civil society within advanced capitalist societies. I examine Gramsci's understanding of the power available to the organic intellectual who is aligned with the interests of subaltern groups and who succeeds in revealing the hegemonic commitments of accepted 'common sense'. In the latter part of this thesis, I apply these many useful concepts to my case study analysis of Betty Friedan's The Feminine Mystique. I argue that Friedan's accessible, middlebrow text gave birth to a new discursive politics which was critically important not only for older women, but for a younger generation of more radicalised women. I emphasise how Friedan's text mounted a concerted attack on the discursive construction of femininity under patriarchal capitalism. I question Friedan's diagnostic claim that the problems American women faced were adequately captured by the terminology of the trapped housewife syndrome. I conclude by arguing that social movement researchers have to date failed to appreciate the leadership potential of the charismatic author-leader who succeeds in addressing and offering a solution to a pressing social problem through the medium of a best-selling, middlebrow text
