Download or read book Madness and Social Representations written by Denise Jodelet and published by Univ of California Press. This book was released on 1991-01-01 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: A striking account of a colony for the mentally ill that forces a reconsideration of madness in society. What happens when the mentally ill are not isolated from society but are instead welcomed into it and invited to take a place in the fabric of the community? Are fear and rejection replaced by the understanding and sympathy often engendered by familiarity? Or are the barriers between the sane and the mad only strengthened? We have experienced a taste of this scenario in the U.S. in the last decade with the new emphasis on de-institutionalization, but Denise Jodelet takes us to an extraordinary community in France where the mentally ill have assumed a visible and prominent role for more than seventy years. The small French town of Ainay-le-Ch�teau and its environs are the site of a "family colony" for men, established in 1900. Here the patients ("lodgers") live with ordinary families ("foster parents"), hold jobs, and are free to move about the countryside. Jodelet's chronicle of daily life in the colony is made rich and vivid by extensive ethnographic material as she unravels a complex set of relationships, ultimately finding that while some of the barriers between the "other" and the larger society have been overcome, new ones have arisen in their place. This unique social experiment provides invaluable social and cultural insights, illuminating many fundamental issues in psychology, psychiatry, and sociology.

Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.

Download or read book The Story of Crass written by George Berger and published by . This book was released on 2009 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-depth interviews with the main movers in the punk rock movement--Crass members Penny Rimbaud, Gee Vaucher, and Steve Ignorant--detail the face of the revolution founded by these radical thinkers and artists. When punk ruled the waves, Crass waived the rules by putting out their own records, films, and magazines and setting up a series of situationist pranks that were dutifully covered by the world's press. Not just another iconoclastic band, Crass was a musical, social, and political phenomenon: commune dwellers that were rarely photographed and remained contemptuous of conventional pop stardom. As detailed in this history, their members explored and finally exhausted the possibilities of punk-led anarchy. This definitive biography of the band not only gives backstage access to their lives, philosophies, and the movement that followed, but also to never-before-seen photographs and rare dialogues.
Download or read book Children s Socio Economic Rights Democracy And The Courts written by Aoife Nolan and published by Bloomsbury Publishing. This book was released on 2011-09-15 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with children's economic and social rights (sometimes referred to simply as children's social rights). Despite increased academic interest in both children's rights and socio-economic rights over the last two decades, children's social and economic rights remain a comparatively neglected area. This is particularly true with regard to the role of the courts in the enforcement of such social rights. Aoife Nolan's book remedies this omission, focussing on the circumstances in which the courts can and should give effect to the social and economic rights of children. The arguments put forward are located within the context of, and develop, long-standing debates in constitutional law, democratic theory and human rights. The claims made by the author are supported and illustrated by concrete examples of judicial enforcement of children's social and economic rights from a variety of jurisdictions. The work is thus rooted in both theory and practice. The author brings together and addresses a wide range of issues that have never previously been considered together in book form. These include children's socio-economic rights; children as citizens and their position in relation to democratic decision-making processes; the implications of children and their rights for democratic and constitutional theory; the role of the courts in ensuring the enforcement of children's rights; and the debates surrounding the litigation and adjudication of social and economic rights. This book thus represents a major original contribution to the existing scholarship in a range of areas including human (and specifically social) rights, legal and political theory and constitutional law. 'Children's rights were often thought to be synonymous with economic and social welfare prior to the adoption of the Convention on the Rights of the Child in 1989. Ironically, since that time, remarkably little scholarship has been devoted to the vitally important economic and social rights dimensions of children's rights. Nolan's book singlehandedly remedies that neglect and does so in a sophisticated, nuanced and balanced way. It provides a superb account of the pros and cons of judicial activism in promoting these rights.' Philip Alston, John Norton Pomeroy Professor, NYU Law School 'Thus far the burgeoning literature on the judicial enforcement of socio-economic rights has failed to engage in a sustained, systemic manner with this topic from the perspective of children and the complexity of their status as citizens within contemporary democracies. This book fills this gap and makes a major contribution to the literature in the three interrelated areas of the judicial review of socio-economic rights claims, children's rights, and democratic theory. Nolan navigates skilfully through the dense, but rich literature in these areas as well as relevant international and comparative law. In so doing she illuminates both the pitfalls and potential of resorting to courts in a partial response to the multifaceted and deeply entrenched global phenomenon of child poverty.' Professor Sandra Liebenberg, HF Oppenheimer Professor of Human Rights Law, University of Stellenbosch Law Faculty. Winner of the Kevin Boyle Book Prize 2012, awarded by the Irish Association of Law Teachers to a book that is deemed to have made an outstanding contribution to the understanding of law.

Download or read book Talking Politics written by Kum-Kum Bhavnani and published by Cambridge University Press. This book was released on 1991-06-06 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1991, this study examines the views of politics presented by young people in contemporary Britain. Bhavnani argues that previous studies of youth and youth culture were limited by too great a reliance on simple survey techniques, and by lack of attention to conceptions of politics amongst young people, and to politics as a series of lived relationships rather than a set of external objects. Instead, she uses ethnographic approaches and open-response interviewing within the broad theoretical framework of social representations. The political is taken to refer to the ways in which people regulate, and attempt to regulate with a view to challenging, unequal social relationships. Within this the specific issues examined are employment, unemployment, youth training schemes, democracy and voting, racism, and marriage. Bhavnani's analysis, organised by themes such as disposable income and social and personal control, tackles questions of power in the research process; and a notion of discursive configurations as distinct from social representations.
Download or read book From Black to African American written by Gina Philogene and published by Praeger. This book was released on 1999-11-30 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of the recent switch from the name Black to African American symbolizes a reconceptualization of Americans of African descent away from race to culture. This book examines the emergence of a new representation whose rapid spread has been fuelled by widely shared projections of a different future capable of overcoming the legacy of racism. Far from being just another label, the new name is capable of representing the group in question by projecting a different future for all of us in a multicultural America based on inclusion, fairness, and equality. Such projections are collectively elaborated, driven by the adoption of African American in the media as a more positive alternative to Black and its equally consistent use among a socio-demographically distinct subgroup of black Americans as a vehicle for a new self-identity. The contradistinction between these two alternative terms implies two different representations of the same group, one still based on race and the other rooted in culture. This tension between race and culture, crystallized in the competing uses of Black and African American, points to a more profound cultural transformation currently under way in America. This book takes a close look at the current state of flux in race relations in the United States through the lens of a social psychologist focusing on the emergence of an alternative name as a new social representation.
Download or read book Religion Personality and Mental Health written by Laurence B. Brown and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: LAURENCE B. BROWN Nearly all the papers in this collection were prepared initially by a group of psychologists interested in the social scientific study of religion. They included some working with the mentally ill in medical, religious, or secular contexts, as well as teachers and researchers in psychology or theology. Their papers aim to test, or to reflect on, common prejudices about the links between mental health and religion, especially when they are thought to be mediated by personality characteristics. All the papers have been revised for this collection. A clear consensus emerged that religion has many positive effects, despite Wulff's (1991" p. 307) unguarded assertion that, "without ques tion the mentally disturbed are frequently attracted by religion." Any assumption that religion is necessarily a "danger" to health, or closely related to mental illness, is not supported by the evidence from carefully controlled studies that follow a social science perspective. Malony's paper, page 16 in this collection, therefore emphasizes that we must take account of the ways in which anyone's religion is integrated into their life, the functions it serves for them and their acceptance by other members of the religious and other groups to which they belong.

Book excerpt: Communication in Development is composed of papers derived from two sources. An International Conference on Social Psychology and Language was held in Bristol in July 1979. Considerations of space rather than merit prevented some of the papers, given in supplementary sessions on language development, from being published in the proceedings. These papers are published in this volume. Also included are recent and hitherto unpublished papers from European researchers working in the field of language and cognitive development. The contents of this volume range from the early non-verbal communicati.
Download or read book The Crisis in Modern Social Psychology written by Ian Parker and published by Routledge. This book was released on 2013-10-18 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1960s a ‘crisis’ erupted in social psychology, with many social psychologists highly critical of the ‘old paradigm’, laboratory-experimental approach. Originally published in 1989, The Crisis in Modern Social Psychology was the first book to provide a clear account of the complex body of work that is critical of traditional social psychological approaches. Ian Parker insisted that the ‘crisis’ was not over, showing how attempts to improve social psychology had failed, and explaining why we need instead a political understanding of social interaction which links research with change. Modern social psychology reflects the impact of structuralist and post-structuralist conceptual crises in other academic disciplines, and Parker describes the work of Foucault and Derrida sympathetically and lucidly, making these important debates accessible to the student and discussing their influence. He assesses the responses from both mainstream social psychology and from avant-garde textual social psychology to the influx of these radical ideas, and discusses the promises and pitfalls of a post-modern view of social action.
