Once thought rare, primary aldosteronism (PAL) is now reported to be responsible for 5–10% of hypertension. Unlike familial hyperaldosteronism type I (FH-I), FH-II is not glucocorticoidremediable and not associated with the hybrid CYP11B1/CYP11B2 gene mutation. At least five times more common than FH-I, FH-II is clinically indistinguishable from apparently sporadic PAL, suggesting an even higher incidence. Studies performed in collaboration with C Stratakis (NIH, Bethesda) on our largest Australian family (eight affected members) demonstrated linkage at chromosome 7p22. Linkage at this region was also found in a South American family (DNA provided by MI New, Mount Sinai School of Medicine, New York) and in a second Australian family. The combined multipoint LOD score for these 3 families is 4.61 (q = 0) with markers D7S462 and D7S517, providing strong support for this locus harbouring mutations responsible for FH-II. A newly identified recombination event in our largest Australian family has narrowed the region of linkage by 1.8 Mb, permitting exclusion of approximately half the genes residing in the originally reported 5 Mb linked locus. Candidate genes that are involved in cell cycle control are of interest as adrenal hyperplasia and adrenal adenomas are common in FH-II patients. A novel candidate gene in this linked region produces the retinoblastoma-associated Kruppel-associated box protein (RBaK) which interacts with the retinoblastoma gene product to repress the expression of genes activated by members of the E2F family of transcription factors.

Immigration is one of the most sensitive issues of modern European politics. Nowhere is this more the case than in Germany, as a result of its history and the sheer scale of immigration it has experienced since 1945. Yet despite this background, Germany's immigration, residence and citizenship policy has been more restrictive when compared to that of many other countries; indeed, official policy long maintained that Germany was not a 'country of immigration'. But why has this been the case? The politics of exclusion provides a new analytical perspective on immigration in Germany, tracing the country's immigration and citizenship policy since the Second World War. The book argues that institutional politics are central to understanding why Germany's policy structures have experienced only incremental change over the past 20 years, and have remained comparatively restrictive. With its lively and accessible style, the book will appeal to advanced scholars and students of immigration and Germany.

This paper explores the representation of the first African World Cup in the British and South African press. Drawing on the output of a variety of media outlets between 2004, when South Africa was awarded the right to host the 2010 event, and the culmination of the tournament in July 2010, this paper contends that a range of representations of Africa have been put forward by the British and South African media. These can be interpreted as alarmist, sensationalist and even racist in certain extreme instances, and hypernationalist and overly defensive in other cases. © 2012 Copyright Taylor and Francis Group, LLC.

In this article we explore the dual role of global university rankings in the creation of a new, knowledge-identified, transnational capitalist class and in facilitating new forms of social exclusion.We examine how and why the practice of ranking universities has become widely defined by national and international organisations as an important instrument of political and economic policy. We consider how the development of university rankings into a global business combining social research, marketing and public relations, as a tangible policy tool that narrowly redefines the social purposes of higher education itself. Finally, it looks at how the influence of rankings on national funding for teaching and research constrains wider public debate about the meaning of ‘good’ and meaningful education in the UK and other national contexts, particularly by shifting the debate away from democratic publics upward into the elite networked institutions of global capital. We conclude by arguing that, rather than regarding world university rankings as a means to establish criteria of educational value, the practice may be understood as an exclusionary one that furthers the alignment of higher education with neoliberal rationalities at both national and global levels.

This article examines the spoken interactions of a group of British construction workers to discover whether it is possible to identify a distinctive ‘builders’ discourse’. Given that builders work for a mostly all-male profession (Curjao, 2006), we ask whether the ways in which male builders converse with each other while ‘on the job’ can be held in any way responsible for the under-representation of women within this major occupational sector in the UK. This article reports on a case study of the conversations of three white, working-class, male builders, which took place while travelling in a truck between different building sites. This forms part of a larger ethnographic study of builders’ discourse in different work locations. The analysis shows that male builders are highly collaborative in constructing narratives of in-group and out-group identities (Duszak, 2002; Tajfel, 1978). Various other male groups are demonized in these conversations: Polish immigrant builders, rude clients and rival builders. However, there is almost no reference to women. The article concludes that women are viewed as so unthreatening to male ascendancy in the building industry that they do not even feature within the ‘out-group’.

This article considers why the family nurse partnership (FNP) has been promoted as a means of tackling social exclusion in the UK. The FNP consists in a programme of visits by nurses to low-income first-time mothers, both while the mothers are pregnant and for the first two years following birth. The FNP is focused on both teaching parenthood and encouraging mothers back into education and/or into employment. Although the FNP marks a considerable discontinuity with previous approaches to family health, it is congruent with an emerging new approach to social exclusion. This new approach maintains that the most important task of social policy is to identify quickly the most 'at-risk' households, individuals and children so that interventions can be targeted more effectively at those 'at risk', either to themselves or to others. The article illustrates this new approach by analysing a succession of reports by the Social Exclusion Unit. It indicates that there is a considerable amount of ambiguity about the relationship between specific risk-factors and being 'at risk of social exclusion'. Nonetheless, this new approach helps to explain why British policy-makers may have chosen to promote the new FNP now. © 2009 Cambridge University Press.

Cell exclusion is the phenomenon whereby the hematocrit and viscosity of blood decrease in areas of high stress. While this is well known in naturally occurring Poiseuille flow in the human body, it has never previously been shown in Couette flow, which occurs in implantable devices including blood pumps. The high-shear stresses that occur in the gap between the boundaries in Couette flow are known to cause hemolysis in erythrocytes. We propose to mitigate this damage by initiating cell exclusion through the use of a spiral-groove bearing (SGB) that will provide escape routes by which the cells may separate themselves from the plasma and the high stresses in the gap. The force between two bearings (one being the SGB) in Couette flow was measured. Stained erythrocytes, along with silver spheres of similar diameter to erythrocytes, were visualized across a transparent SGB at various gap heights. A reduction in the force across the bearing for human blood, compared with fluids of comparable viscosity, was found. This indicates a reduction in the viscosity of the fluid across the bearing due to a lowered hematocrit because of cell exclusion. The corresponding images clearly show both cells and spheres being excluded from the gap by entering the grooves. This is the first time the phenomenon of cell exclusion has been shown in Couette flow. It not only furthers our understanding of how blood responds to different flows but could also lead to improvements in the future design of medical devices.

The past decade has seen a drive to give all pupils the opportunity to study a Modern Foreign Language (MFL) in schools in England, making the teaching and learning of foreign languages part of the primary school curriculum. The Languages for All: Languages for Life (DfES, 2002) policy was introduced through the National Languages Strategy with an objective to increase the nation’s language capability. Raising the educational standard for all pupils is another government initiative with a strong emphasis on inclusion. As the Languages for All policy stresses the importance and benefits of language learning, and inclusion suggests equality and provision for all, this study examines the inclusion of all key stage 2 pupils in foreign language learning and describes perceptions and experiences of pupils, particularly those identified as having special educational needs (SEN) in their performances and negotiations in learning French. As a small scale, qualitative and ethnographically informed, this research is based on participant observation and semi-structured interviews with pupils, teachers of French, teaching assistants and parents. This study draws upon Nussbaum’s capabilities approach and Bourdieu’s concepts as theoretical foundations to analyse the ‘inclusive’ French classroom. As the capabilities approach takes people as ends not means, and goes beyond a focus on resources, it lends itself to critical thinking on issues around inclusion in education. In this context, this researcher investigates the experiences of pupils who struggle with foreign language learning because of their abilities or disabilities, and frames the discussion around the capabilities approach. The study also focuses on motivation and identity in foreign language learning, and draws upon Bourdieu’s concepts of capital, habitus and field to analyse how the participants make sense of and respond to their own circumstances in relation to their performances in the language learning process. This research thus considers Bourdieu’s concepts for a deeper understanding of issues of inequality in learning French and takes up Nussbaum’s insight that pupils may differ in what learning French means to them, and it is not how they differ, but the difference between their capability to choose and achieve what they value that should matter. The findings indicate that although, initially, the French classroom appears ‘inclusive’ due to the provision and practices of inclusion, a closer look shows it to be exclusionary. In addition, responses from the participants on the usefulness and benefits of foreign language learning are contradictory to the objectives of the Languages for All policy, illustrating the complexity of the ‘inclusive’ MFL classroom. This research concludes that structural and interpersonal practices of inclusion contribute to the disguising of exclusion in a classroom deemed ‘inclusive’. Implications are that an understanding and consideration of other aspect of life such as well-being, interests, needs and values should form a necessary part of the language policy.

This article focuses on the involvement and management of spontaneous volunteers (SVs). It develops a new theory—which we call the “involvement/exclusion” paradox—about a situation which is frequently manifested when SVs converge in times of disaster. After reviewing research and policy guidance relating to spontaneous volunteering, we present findings from a study of responses to winter flood episodes in England. Taking together the empirical findings and the literature, the article analyzes elements inherent in the involvement/exclusion paradox and develops a conceptual model to illustrate and explain the paradox. Implications for managers and future research are discussed.

This dissertation documents the everyday lives and spaces of a population of youth typically constructed as out of place, and the broader urban context in which they are rendered as such. Thirty-three female and transgender street youth participated in the development of this youth-based participatory action research (YPAR) project utilizing geo-ethnographic methods, auto-photography, and archival research throughout a six-phase, eighteen-month research process in Bogotá, Colombia. ^ This dissertation details the participatory writing process that enabled the YPAR research team to destabilize dominant representations of both street girls and urban space and the participatory mapping process that enabled the development of a youth vision of the city through cartographic images. The maps display individual and aggregate spatial data indicating trends within and making comparisons between three subgroups of the research population according to nine spatial variables. These spatial data, coupled with photographic and ethnographic data, substantiate that street girls’ mobilities and activity spaces intersect with and are altered by state-sponsored urban renewal projects and paramilitary-led social cleansing killings, both efforts to clean up Bogotá by purging the city center of deviant populations and places. ^ Advancing an ethical approach to conducting research with excluded populations, this dissertation argues for the enactment of critical field praxis and care ethics within a YPAR framework to incorporate young people as principal research actors rather than merely voices represented in adultist academic discourse. Interjection of considerations of space, gender, and participation into the study of street youth produce new ways of envisioning the city and the role of young people in research. Instead of seeing the city from a panoptic view, Bogotá is revealed through the eyes of street youth who participated in the construction and feminist visualization of a new cartography and counter-map of the city grounded in embodied, situated praxis. This dissertation presents a socially responsible approach to conducting action-research with high-risk youth by documenting how street girls reclaim their right to the city on paper and in practice; through maps of their everyday exclusion in Bogotá followed by activism to fight against it.^
