Background: Ugandan law prohibits abortion under all circumstances except where there is a risk for the woman's life. However, it has been estimated that over 250 000 illegal abortions are being performed in the country yearly. Many of these abortions are carried out under unsafe conditions, being one of the most common reasons behind the nearly 5000 maternal deaths per year in Uganda. Little research has been conducted in relation to societal views on abortion within the Ugandan society. This study aims to analyze the discourse on abortion as expressed in the two main daily Ugandan newspapers. Method: The conceptual content of 59 articles on abortion between years 2006-2012, from the two main daily English-speaking newspapers in Uganda, was studied using principles from critical discourse analysis. Results: A religious discourse and a human rights discourse, together with medical and legal sub discourses frame the subject of abortion in Uganda, with consequences for who is portrayed as a victim and who is to blame for abortions taking place. It shows the strong presence of the Catholic Church within the medial debate on abortion. The results also demonstrate the absence of medial statements related to abortion made by political stakeholders. Conclusions: The Catholic Church has a strong position within the Ugandan society and their stance on abortion tends to have great influence on the way other actors and their activities are presented within the media, as well as how stakeholders choose to convey their message, or choose not to publicly debate the issue in question at all. To decrease the number of maternal deaths, we highlight the need for a more inclusive and varied debate that problematizes the current situation, especially from a gender perspective.

The emancipatory goal that underpins critical theories of teaching and learning is built on a theory of rational self-determination. In the context of physical education, critical educators believe that through a process of enlightenment teachers can recognize and transform elements of injustice and inequality that exist, albeit unwittingly, in their practice. However, despite the broad appeal of this orientation there are relatively few empirical accounts of how theories of enlightenment manifest themselves in the practice of emancipation. Propelled by the lacuna that clearly exists between critical theory and critical practice, this paper reports on the introduction of critical social discourses to a preservice PE program. It uses a case study methodology to report on two student-teachers' engagement with a range of critical social discourses during a year-long PE unit. The paper discusses some of the ways these students engaged with the theory and practice of a critical orientation for teaching and learning in physical education. Aspects of their experiences are then interpreted through Fay's (1987) critical but postmodern "limits to change" thesis. The paper concludes with tempered optimism about the potential for critical social discourses to guide preservice teachers in practical ways.

This paper begins by noting the range of contradictions and dilemmas facing those involved in community development today. It then draws on research into the operating frameworks that set the stage for much current community development activity. It discusses four key operating frameworks and how each framework can affect community development practice. The final section deals with the ways in which the frameworks, and the discourses associated with them, come together.

Cheating, it is claimed, is anathema to sport. But is this the case? In this paper it is argued that cheating is integral to modern sport, that the model of sport as 'fair play' is simply an ideological guise of amateurism. The paper focuses on the sport of professional running which, since its origins in the eighteenth century, has been a gambling sport. Strategies involving cheating to manipulate wins, or losses, have featured in this sport as ways of increasing the probability of striking successful wagers. Such strategies are an accepted part of professional running: participants anticipate and expect others to be playing it in this way. However, a distinction is made between what is referred to in the paper as 'clean' cheating and 'dirty' cheating. The former is an accepted way of the sport, the latter occurs but is deprecated. The paper explores these different forms of cheating and the athletes' responses to them. Through a focus on the discourses of success in capitalist society, a model of cheating is developed to interpret such practices. Within the context of professional running, a working class sport, it is argued that, given the habitus of its practitioners, 'success' may be measured in terms of monetary gains and the 'kick-on' in life that these might provide. Cheating practices may serve to enhance the probability of success and social mobility. Given the relatively short career spans of sports people and the costs involved in developing the requisite skills, cheating may promote success and establish a financial base for post-sport careers. The paper concludes that cheating in sport can be anticipated as a feature of an acquisitive capitalist society.

This article examines the notion of the 'scientist as a moral person' in the light of the early stages of the commodification of science and the transformation of research into a big enterprise, operating on the principle of the division of labour. These processes were set in train at the end of the 19th century. The article focuses on the concomitant changes in the public persona and the habitus of scientific entrepreneurs. I begin by showing the significance of the professional networks that were built up and maintained to further a group's research ideas and the careers of its members, thus demonstrating one condition on which depended their practice of science and their ability to earn a living. This leads to a characterization of the changing styles of work, thought and life, and to a consideration of public perceptions and of the ways in which a new self-image of scholarship and science was fashioned. A critical discussion of the public role of these mandarin scientists follows in order to highlight the strains created by the commodification of science at a time of international tensions and conflicts, when shared beliefs in scholarly cosmopolitanism were subverted by appeals to science and scholarship to work in the service of one's own nation as its 'courtiers'. Various considerations of peculiar analogies between national styles of research and the style of social organization are then noted. In the final section, the article queries the long-term impact of these developments on the ideal of the scientist as a 'moral person'. Taking a cue from Max Weber and pursuing reflections by Zygmunt Bauman on 'science moralized', I argue that the emergence of a type of 'specialists without spirit' was an unintended but fatal consequence of the changes in research practices promoted by scientific entrepreneurs such as Du Bois-Reymond. I conclude that the temptation to sever the ties to a general ethos of civil virtues lay in the rationalization, specialization and potential de-humanization of the objectifying scientific outlook once advocated for its efficiency.

This paper explores the scientific reasoning of 14 children across their first two years of primary school. Children's view of experimentation, their approach to exploration, and their negotiation of competing knowledge claims, are interpreted in terms of categories of epistemological reasoning. Children's epistemological reasoning is distinguished from their ability to control variables. While individual children differ substantially, they show a relatively steady growth in their reasoning, with some contextual variation. A number of these children are reasoning at a level well in advance of curriculum expectations, and it is argued that current recommended practice in primary science needs to be rethought. The data is used to explore the relationship between reasoning and knowledge, and to argue that the generation and exploration of ideas must be the key driver of scientific activity in the primary school.

This article explores the political beliefs and the forms of reasoning about racism, national identity and Other developed by young Australian women and men from different ethnic and class backgrounds. The interviews on which the discussion is based are drawn from a larger longitudinal study of Australian secondary school students which examines how young people develop their sense of self and social values over time. The present article has two overall purposes: to add to understandings of how the cultural logic of racism functions in one national setting, and to consider political reasoning about race and ethnicity in relation to processes of young people's identity positioning. Three main lines of argument are developed. The first concerns students' positioning of themselves vis-a `-vis the current 'race debate' in Australia, and in relation to us as researchers, including their negotiation of the protocols for speaking about 'race' and racism. This includes consider ation of the methodological and political effects of white Anglo women asking questions about racism and ethnicity to ethnic minority students who are routinely constituted as 'Other': what blindnesses and silences continue to operate when posing questions about racism directly? A second and related focus is the range of emotional responses evoked by asking questions about racism and about an Australian politician (Pauline Hanson), who has been prominent in race debates. Third, the authors examine young people's construction of 'us and them' binaries and hierarchies of Otherness and whiteness. They argue throughout that reasoning about race, national identity and Others, and the taking up of 'political positions', is intimately linked to identity formation and to how we imagine ourselves in the present, the past and the future.

It is often assumed that picture books are intended for young children and that they are therefore mainly concerned with safe and reassuring stories, say, about home and family, friends and starting school. There are many picture books which fit within this category, but the form itself, a 32-page format which developed during the 1960s from illustrated books, has always been peculiarly open to experimentation and has enlarged its audience to include older children and adults. Unlike the novel, the picture book is not weighed down by the practices and conventions of the past; and the combination of verbal and visual texts makes for a particularly complex genre as it constructs ideas through dialogical relations between words and pictures.
