In 1994, South Africans embarked on a project to create new meanings of citizenship in order to transcend the disenfranchisement and divisions created by apartheid. This article examines the context in which new forms of citizenship are evolving in South Africa and how South African citizens use the media to give meaning to concepts such as “an active public sphere,” “civic agency” and “participatory politics.” The objective of the research is to provide information about the way in which the media contribute to the quality of democracy in South Africa through mediating citizenship in a way that improves prospects for citizens to exert influence over public decisions. As has been the case in other post-authoritarian and postcolonial settings, the continuation of existing unequal relationships to government persists even when new democratic spaces have opened up. This article interrogates the assumption that media are central to citizens’ political and civic engagements in a transitional society marked by persisting inequalities. This interrogation draws on empirical research with citizens to investigate the question that the media are central to constructions of citizenship and participation and engagement with democratic processes. Our research finds that young South Africans interviewed are disengaged from politics and find that the media does not speak to or connect with their everyday lives. They view the state on both national and local levels as not being prepared to listen to their experiences, ideas or conditions of life. While the respondents trust the media as credible institutions, they do not experience the media as being relevant to their lives. The perceived disinterest of the state and the lack of relevance of the media, work together to create a sense of powerlessness and inability to influence policy-making among the young people interviewed. For the media to intervene in this state of affairs, it would have to create more opportunities for young people to participate directly in meaning production through the media, starting by listening more closely to their experiences in order to respond to their concerns in a relevant way. 相似文献

Derrida’s account of forgiveness appears to oppose politics to ethics, challenging political reconciliation in the name of unconditional forgiveness. Yet at the same time Derrida seems to sacrifice ethics to politics by advancing but refusing to take the side of what he calls an “indecent objection” to reconciliation. This essay seeks to account for Derrida’s strategy and to think through some of the consequences of Derrida’s emphasis on the “impossibility” of forgiveness. 相似文献

ABSTRACTExperimental vignettes were used to investigate attributions relating to child sexual abuse with a focus on the degree of blame allocated to the family and to society, factors thought to be particularly relevant in a collectivist society. One hundred and sixty-two undergraduates in Singapore evaluated media reports describing a case of child sexual abuse. A 2 x 2 x 2 between-subjects design manipulated victim sex, perpetrator sex, and victim–perpetrator relationship. Participants rated the vignettes on degree of blame and prevention potential and rated the abusiveness of the case. Individualism and collectivism attitudes of the participants were also measured. While the highest blame ratings were attributed to perpetrators, significantly more blame was attributed to the family and to society than to the victim. The demonstration of the present attributions of blame to family and to society is a timely finding given recent recommendations to broaden approaches to child abuse prevention by moving away from a reliance on school based child protection programs, which leave the onus on the child to prevent and report abuse, toward a public health approach, which is particularly inclusive of parent and community education approaches . Allocation of some blame to victims, in spite of their status as children, while not a unique finding in victimology research, emphasizes the challenges still to be faced in encouraging the reporting of child sexual abuse. 相似文献

Earlier work on the preparation of student teachers to deal with child protection concerns had indicated that initial teacher training (ITT) providers were often struggling to determine what to include on the subject and who should provide the input, as well as coping with the difficulty of trying to fit it into an overfull curriculum. In an attempt to support this work, the National Society for the Prevention of Cruelty to Children (NSPCC) developed a course for this group of students. Although an evaluation indicated the need for the materials to be redrafted, the views of both those involved in the exercise and a subsequent survey of ITT providers not only contributed to the redraft but also to the debate around the most effective approach to training professionals to protect children and young people.

The insights from one state illustrate the challenges of working to shape public will to favor support for out-of-school learning opportunities for youth ages nine to fifteen. With the leadership of the Frameworks Institute, local and national research and refraining concepts were used to develop a strategy to help advocates communicate the value of these learning opportunities in ways the public is less likely to dismiss out of hand. Messages reinforcing the developmental need to practice skills using the illustration of brain architecture and emphasizing the important role of community contribution on future leadership proved to be important aspects of the communication strategy. 相似文献

Connecting Tenure Security with Durable Solutions to Internal Displacement: From Restitution of Property Rights to the Right to Adequate Housing 下载免费PDF全文
Patricia García Amado 《International migration (Geneva, Switzerland)》2016,54(4):74-86
The end of displacement is a main goal of international peacebuilding strategies, with increasing financial and human resources committed to it. Nevertheless, protracted internal displacement remains unabated, necessitating a review of the responses provided thus far. Durable solutions to internal displacement require a safe, permanent and secure place to settle, which puts security of tenure at the centre of any sustainable option. This article emphasizes the limited understanding of the factors that contribute to secure tenure as one of the main flaws in a predominantly legal approach to the right to restitution and the right to adequate housing in responses to internal displacement. It calls for the design of contextualized and inclusive strategies to align the de jure, de facto and perception dimensions of tenure security to support the sustainable settlement of internally displaced persons as well as the construction of peace. 相似文献

This paper discusses the barriers encountered in undertaking an oral history project with survivors of a total institution for 'mental defectives' in the province of Alberta, Canada. Powerful social actors were able to bar access to survivors through legal guardianship orders, and to make access to the institution and its grounds and to publicly archived materials quite prohibitive to the researcher. In addition to overt efforts on the part of powerful social actors to block the project, concerns about the potential to discredit survivor narratives led to changes in the research design. Specifically, research and literature about the 'acquiescence' of intellectuals with intellectual impairments led the researcher to broaden the sources for this history as a preemptive strategy. Despite these barriers, survivors of the institution provided a rich and powerful testimony to the brutality of institutionalization, and provide us with an emancipatory history from the perspectives of those most oppressed by disability policies and practices. 相似文献

The present article delineates the state of health and socioeconomic situation of migrants and refugees in Sweden. Special attention is given to refugees. Migrants appear to have more extensive health problems and a shorter longevity span than native Swedes. The refugees constitute an especially exposed group of migrants. Experiences in the home country that relate to organised violence is a specific problem for this group. It has been estimated that 20 to 25 per cent of all adult refugees who have arrived to Sweden during the recent years have experienced torture in their native countries. Swedish migrant and refugee policy operates according to a model of decentralisation, aiming to avoid ethnic segregation in the big city areas. However, the integration policy seems, in many instances, to have had a negative affect on the situation of the refugees. During the period of time, in which the refugees wait for a residence permit, they are not permitted to work. The long period of forced inactivity—in some instances up to a couple of years—seems frequently to have aggravated the health of the refugees. In addition it appears to contribute to the ever increasing animosity towards them. 相似文献
