Disciplinary knowledge for what ends? The values dimension of curriculum research in the Anthropocene

This article makes the case for repositioning values and ethics as central to understanding how curriculum knowledge can be educationally powerful. Disciplinary knowledge can help individuals make sense of the present, explore alternative futures and participate in society, making ethical choices about how to live. This, however, depends on particular relationships between curriculum, disciplinary knowledge, values and ethical perspectives. We argue that the recent research agenda exploring disciplinary knowledge underplays the values dimension in how curriculum knowledge is constructed and used. First, we give an overview of the recent thrust of curriculum debates in subject education communities, placing this in some historical context. Here, we recognise the need to make a robust case for school subjects and their important relationship with disciplines. We go on to examine some arguments around the role of knowledge in curriculum. Taking the concept of the Anthropocene (the human epoch of the planet) and from our perspectives as geography and religious education educators, we propose a focus on ethical disposition and interdisciplinarity to make the values dimensions of curriculum knowledge more visible

Land suitability studies for the growing of deciduous berries in the Limpopo Province of South Africa

Blueberry, Cherry and Raspberry (berry) production is a potential alternative land use opportunity in the Limpopo Province (LP) of South Africa (RSA). RSA based site selection criterion and literature is limited. Haenertsburg and an area near Pietersburg (Polokwane) were identified for berry production potential. In Haenertsburg, most viable land is held by the timber industry. In Pietersburg, soil and climatic conditions vary greatly, representing a site selection risk. Using accepted site selection processes, a study was conducted which identified the need to select land qualities and characteristics (QC’s) appropriate to berry production. The study revealed key QCs’ and secondary QCs’. Key QCs’ must be adhered to for site selection, while secondary QCs’ have site-specific application. The key land qualities are climate, soil, water, topography and management. In order to design a land rating system (LRS), specific characteristic values were cataloged per quality and per berry. Characteristic values were assigned to a land rating system where S1 (highly suitable), S2 (moderately suitable), S3 (marginally suitable), N1 (currently not suitable) and N2 (not suitable). To test the LRS, a real, but non-representative resource assessment (RA) took place. The RA revealed the further need to incorporate land limits into site selection. QCs’ and land limit data was collected from existing sources and measured in situ where the data was insufficient. Finally the RA data was applied to the LRS through the process of matching. The matching precipitated the formation of a site selection process or tool, presented on tables. Each table represents a land quality. Water and soil criteria varied per berry, while topography, water and management were common to all three berries. Additionally, the site selection tool enabled the assessment of secondary QCs’. The assessment process is conservative, allocating the lowest land rating as the overall rating. This allows for the land user to address the most limiting factor from worst to least, thereby ensuring sustainable and good land use.Dissertation (MInstAgrar (Land-Use Planning))--University of Pretoria, 2008.Plant Production and Soil Scienceunrestricte

Kaposi sarcoma in South African children

This article has been published as part of Infectious Agents and Cancer Volume 5 Supplement 1, 2010: Proceedings of the 12th International Conference on Malignancies in AIDS and Other Acquired Immunodeficiencies (ICMAOI).The AIDS epidemic has contributed to an abrupt increase of the incidence of Kaposi sarcoma, especially in Sub-Saharan Africa, to values tens of times higher than in the pre-epidemic era. There is, however, very little literature concerning the clinical features of this disease and its management and outcome in HIV-positive children in Africa.Peer Reviewe

Primary pulmonary lymphoepithelioma-like carcinoma in a 12-year-old African child

Pulmonary lymphoepithelioma-like carcinoma is a rare malignant tumour predominantly occurring in Asian patients. It has identical histological features to nasopharyngeal carcinoma. To date, Epstein–Barr virus (EBV) in pulmonary lymphoepithelioma-like carcinoma has been limited to the Asian population. This manuscript presents an unusual case in a 12-year-old African boy in which the tumour tested positive for EBV

The South African paediatric tumour registry - 25 years of activity

The South African Children’s Tumour Registry was established 25 years ago as it was essential to collect data on malignant disease in the paediatric population that can be used for statistical research in an efficient and sustainable way. The Registry is a useful and significant repository of specific paediatric data, along with the recently revitalised National Cancer Registry, to serve the needs of the cancer research community

Greater involvement of people living with HIV in health care

Greater Involvement of People Living with HIV/AIDS represents a mobilising and an organising principle for the involvement of people living with HIV in program and policy responses. People with HIV have been at the forefront of designing and implementing effective HIV treatment, care and prevention activities. However, governments and health systems have yet to act to fully harness the potential and resources of people living with HIV in addressing the epidemic
