- ItemRestrictedCurrent patterns of habitat transformation and future threats to biodiversity in terrestrial ecosystems of the Cape Floristic Region, South Africa(2003) Rouget, Mathieu; Richardson, David M; Cowling, Richard M; Lloyd, J Wendy; Lombard, Amanda TThe formulation of an effective strategic plan for biodiversity conservation in the Cape Floristic Region (CFR) requires an assessment of the current situation with regard to habitat transformation, and an explicit framework for predicting the likelihood of remaining habitat (i.e. that potentially available for conservation) being transformed. This paper presents the results of a detailed assessment of the current and future extent of three important factors that threaten biodiversity in the CFR: cultivation for intensive agriculture (including commercial forestry plantations), urbanisation, and stands of invasive (self-sown) alien trees and shrubs. The extent of habitat transformation was mapped at the scale of 1:250,000, using primarily satellite imagery. We compared models derived from a rule-based approach relying on expert knowledge and a regression-tree technique to identify other areas likely to be affected by these factors in future. Cultivation for agriculture has transformed 25.9% of the CFR and dense stands of woody alien plants and urban areas each cover 1.6%. Both models predict that at least 30% of the currently remaining natural vegetation could be transformed within 20 years. There was an overall accuracy of 73% between both models although significant differences were found for some habitat types. Spatial predictions of future agriculture threats derived from the rule-based approach were overestimated relative to the statistical approach, whereas future alien spread was underestimated. Threat assessment was used to derive conservation targets for subsequent stages of conservation planning for the CFR. The importance of integrating vulnerability knowledge into conservation planning is discussed. The choice of vulnerability analysis (future habitat degradation and/or impact on biological entities) and methods will depend on the complexity of the threatening processes and the availability of spatial data.
- ItemOpen AccessEthical challenges in global health-related stigma research(2019-04-29) Millum, Joseph; Campbell, Megan; Luna, Florencia; Malekzadeh, Arianne; Karim, Quarraisha ABackground It is critically important to conduct research on stigmatized conditions, to include marginalized groups that experience stigma, and to develop interventions to reduce stigma. However, such research is ethically challenging. Though superficial reference is frequently made to these widely acknowledged challenges, few publications have focused on ethical issues in research on stigmatized groups or conditions. In fact, a brief literature review found only two such publications. Main text At a recent Science of Stigma Reduction workshop comprising 60 stigma researchers from the USA and low and middle-income countries, the need for more robust and critical discussion of the ethics of the research was highlighted. In this paper we describe, illustrate through cases, and critically examine key ethical challenges that are more likely to arise because a research study focuses on health-related stigma or involves stigmatized groups or conditions. We examine the ethics of this research from two perspectives. First, through the lens of overprotection, where we discuss how the perception of stigma can impede ethical research, disrespect research participants, and narrow the research questions. Second, through the lens of research risks, where we consider how research with stigmatized populations can unintentionally result in harms. Research-related harms to participants include potential breaches of confidentiality and the exacerbation of stigma. Potential harms also extend to third parties, including families and populations who may be affected by the dissemination of research results. Conclusions Research with stigmatized populations and on stigmatized conditions should not be impeded by unnecessary or inappropriate protective measures. Nevertheless, it may entail different and greater risks than other health research. Investigators and research ethics committees must be particularly attentive to these risks and how to manage them.
- ItemOpen AccessFlourishing in fragility: how to build antifragile ecosystems of learning, that nurture healthy vulnerability, in fragile environments in the Western Cape (South Africa) with at-risk learners(2019) Youngleson, Penelope; Nilsson, WarrenThis research is a qualitative, autoethnographic study of antifragility in fragile spaces. It was written using data from Applied Theatre workshops, rehearsals and exercises; as well as questionnaires, semi-structured interviews and open discussions in focus groups with at-risk learners from Quintile 1-3 high schools, their educators, senior management staff, parents, caregivers and peers. Methodologically, social constructionism functioned as the schematic map that positioned the writing/writer between the self and others, and provided the philosophical scaffolding necessary to elucidate data analysis and interpretation. Institutional theory and organisational culture centered the analytical framework once thematic analysis had been conducted across the data sets. This reflexive, feminist paper exhumes and explores fragile spaces in Western Cape Quintile 1-3 schools, using drama and conscious, performed acts of vulnerability (on and off stage) as a means of activating antifragility in the performer and the observer. The data collection took place in the Western Cape in South Africa, and specifically refers to learners and their networks and blended learning ecosystems in that context. Noted conversants include Brown, Taleb and Butler. The findings of this study include a shift in how we define “success” in a fragile environment and an acknowledgment of antifragility as a strategy that is always in motion. Static achievement and a singular definition of learner excellence are shown to be the undesirable opposite of iterative antifragility and adaptive, holistic executive function and socio-cultural competence; and learner wholeness (as experienced and embodied by the learner themselves) is referred to as “flourishing”.
- ItemRestrictedPredicting the social consequences of orphanhood in South Africa(Taylor & Francis, 2003) Bray, RachelThis paper examines and questions the predictions found in the academic and policy literature of social breakdown in southern Africa in the wake of anticipated high rates of orphanhood caused by the AIDS epidemic. Analysis of the logic underlying these predictions reveals four causal relationships necessary to fulfil such dramatic and apocalyptic predictions: 1 High AIDS mortality rates will produce high numbers of orphans. 2 These orphans will become children who do not live in appropriate social environments to equip them for adult citizenship. 3 Poor socialisation will mean that children orphaned by AIDS will not live within society’s moral codes (becoming, for example, street children or juvenile delinquents). 4 Large numbers of such ‘asocial’ or ‘antisocial’ children will precipitate a breakdown in the social fabric. Evidence for each of these steps in the argument is scrutinised using available data from southern Africa and other regions that have moved further through the epidemic’s cycle. The paper finds strong evidence for the first step, although variable definitions of ‘orphan’ make it difficult to draw accurate comparisons over time and space. Evidence for the second step is found to be mixed in terms of outcomes of AIDS orphanhood for child well-being. Moreover the argument takes little account of the social and eco- nomic environments onto which AIDS is mapped, including the economic fragility of households and pervading socio-cultural patterns of child-rearing. Data to substantiate the third step are anecdotal at best and no research is able to demonstrate a link between the long term effects of AIDS orphanhood and rising rates of juvenile delinquency. Arguments made towards the fourth step are shown to be based heavily on notions of the ‘correct’ social and physical environments for children and on unsubstantiated fears of alternatives to these. There is no evidence from countries where numbers of AIDS orphans are already high to suggest that their presence is precipitating social breakdown. The paper argues — somewhat provocatively — that such apocalyptic predictions are unfounded and ill-considered. By misrepresenting the problems faced by children and their families, attention is distracted from the multiple layers of social, economic and psychological disadvantage that affect individual children, families and communities. Consequently, insufficient consideration is given to the multi-faceted supports necessary to assist children to cope with extremely difficult circumstances brought about over the long term by the HIV/AIDS epidemic
- ItemRestrictedWho Does the Housework? An Examination of South African Children's Working Roles(Taylor & Francis, 2003) Bray, Rachel
This paper examines childrens' participation in housework as a form of child labour. This is a particular concern in South Africa because of the possibility that children are being burdened with additional work due to HIV/AIDS. The analysis contextualises children's work in the home within broader socioeconomic trends and cultural norms around child-rearing, thus exposing the need to question the classification of different types of 'work' and 'risk' used in surveys. Ethnographic research revealed that the participation of children in everyday household chores is viewed as a function of their roles as members of a household and family, as part of their duty to their seniors and as an opportunity to learn skills required in adulthood. In this context, risk factors to child well-being are related not to their working roles, but to aspects of the broader socio-economic and physical environment that restrict or compromise children's development opportunities. A key lesson to be drawn from this paper is that the ability to question and re-frame international measurement criteria relies on the availability of longitudinal surveys and qualitative research on childhood, schooling and household dynamics in a variety of contexts in South Africa.
