Learning about sustainability through experiencing complex, adverse conditions typical of the South : reflections from the African Catchment Games played in Finland 2008

- Description: The African Catchment Game is an innovative role playing game which was played twice in Finland in 2008 as part of the CIMO funded collaboration between Finland Futures Research Centre and Rhodes University. It simulates a "real imaginary country" and enables participants to explore and experience how southern countries may or may not develop scenarios of sustainable resource extraction and consumption. New processes modelling climatic variability, water management and consumption were introduced for these two game runs. This imaginary country has roles for an urban/industrial sector, the informal sector, trading intermediaries, overseas trade, a government comprised of a president and two ministers, peasant and commercial farmers. Chapman's original game, Green Revolution Game/Exaction, is based on systems and complexity theories from the 1970s and 1980s. Our modifications to Chapman’s game are underpinned by theories of Complex Adaptive Systems and educational approaches based on constructivist, active/experiential learning models. The paper presents an analysis of the two Finnish games from the perspectives of the participants and the game managers. Participants’ information came from pre and post game questionnaires and the focus group discussions that were part of the debriefing pro-cess. These two methods enabled us to examine the local and network processes which de-veloped during the games. Global scale processes of production, consumption, resource utilization, trading and water provision was collected by the game managers as part of their management processes throughout each game run. Our analysis shows that the par-ticipants’ understanding altered and deepened as a result of playing the game. The nature of the game, as a Complex Adaptive System, and the constructivist learning approach through which the game is experienced means that lessons of a more universal nature cannot be extrapolated.

- Description: The business sector has a substantial role in addressing current environmental issues and concerns. Consequently, there is a growing adoption of corporate sustainability principles and practices across all market sectors. This study examined four developed and four emerging stock markets and the sustainability reporting practices of the top 20 and bottom 20 companies in each. The results illustrate that the developed market sector was more advanced in its corporate sustainability reporting, both in the proportion of companies issuing a sustainability report (approximately 60 per cent) and the proportion of company webpages dedicated to sustainability reporting. This difference was largely due to the effect of the top 20 companies. There was little difference between developed and developing markets when only the bottom 20 companies were considered, of which less than one-third provided sustainability reports. These results show that sustainability reporting is prevalent in both developed and developing markets, especially among market leading companies, but that overall, most developing markets have some catching up to do.

The need for an inland fisheries policy in South Africa : a case study of the North West Province

- Description: In contrast to many other African countries, inland fisheries in South Africa are poorly developed and the fish populations in many of the country’s 3 000 major dams are under-utilised. While the primary purpose South Africa’s dams is to supply water for domestic and agricultural use, there has been an increasing realisation that their fish populations could make a contribution to food security through the establishment of capture fisheries. Historically, the fish in most South African dams have primarily been utilised for recreational fishing purposes, as subsistence use was criminalised by the apartheid regime in all waters except in the former homeland areas. This legacy persists as many of South Africa’s rural communities do not have a fishing tradition and there is a lack of an institutional framework to facilitate managed and sustainable access to the fish resource in inland waters. Current utilisation of many inland dams is often complicated by the existence of multiple authorities and interest groups, often with competing agendas. As a result, the economic potential of these water bodies is unknown and often grossly underutilised. Our study outlines a case study of fisheries resources in the North West Province of South Africa that could be used for the creation of income and food security for local communities through the development of subsistence, commercial, and recreational fisheries. The study identifies the lack of guidelines for the development of inland fisheries and the lack of an inland fisheries policy, both at the provincial and national level, as major bottlenecks for the sustainable development of these resources and outlines possible focal areas for intervention.

- Description: Many plants, especially woody species, introduced into South Africa for ornamental or commercial purposes, have become invasive in a number of habitats. Because of the risk of an invasion of coastal dunes by yet another species, the European dune grass Ammophila arenaria, used as a dune stabilizer, is assessed using lists of attributes of invasive species and invasible ecosystems. It is impossible to predict plant invasions, but both invasive species as well as invaded ecosystems are often characterized by certain attributes which facilitate invasions. Many of the species attributes connected with invasion appear to apply to A. arenaria. Above all, the grass is characterized by ecological tolerance and vigorous rhizomatous reproduction. An important site attribute connected with invasion is an evolutionary history with isolation patterns, which applies to the South African Cape coast. We conclude also on the basis of the overseas experience, that the potential for A. arenaria to become invasive needs urgent investigation in the South African context.

Economic feasibility of an experimental octopus fishery in South Africa

- Description: Octopus vulgaris was identified as a new marine resource to be commercially exploited through an experimental fishery. A recent policy on developing fisheries in South Africa emphasizes the importance of investigating the economic feasibility of a fishery as part of its management framework. The study reported here generated baseline information necessary in the design of the experimental fishery, giving guidelines as to which vessels, fishing gear and markets would be most feasible. The proposed fishery, gear and vessel type, fishing techniques and expected catch rates are described, the results of market research are outlined, and the cost of fishing is estimated. The potential business should consist of small and medium-sized vessels deploying unbaited pots attached to long lines. The longline pot fishery could be economically feasible, provided a 30 percent catch in 6600 pots/month is attained. Only existing, debt-free vessels should be used. The minimum catch per unit effort (CPUE) for various fishing operation scenarios was calculated to determine economic feasibility. This is an estimated minimum CPUE, based on assumptions that cannot be confirmed until the fishery starts. Furthermore, this economic analysis also needs to be assessed by stakeholders with experience of fishery operations , Rhodes Centenary issue of: South African Journal of Science.

In the intraspecific tests, significantly more larvae were removed in A. cerana than in A. mellifera, whilst significantly fewer eggs and pupae were removed in A. cerana than in A. mellifera. In the interspecific tests, A. cerana colonies removed significantly more larvae and pupae of A. mellifera than the same brood stages of A. cerana were removed by A. mellifera. We show there are highly significant differences in both intraspecific and interspecific brood recognition between A. cerana and A. mellifera and that brood recognition operates with decreasing intensity with increasing developmental age within species. This suggests that worker policing in egg removal is a first line of defense against heterospecific social parasites.

- Description: Model C Schools have created great controversy in recent educational policy debate. SADTU has joined the fray in opposition to the retention of these schools. Model C is a particular type of state aided school which is different to state aided schools like the farm schools that came under the authority of the former black Department of Education and Training (DET). The latter schools were mostly poorly resourced and inadequately staffed. Model C schools are state aided schools that have governing bodies elected by the parents, with power over a number of key functions of the school. These include control over admissions policy, the power to charge compulsory school fees and to raise funds by other means (e.g. renting out the school's property), the power to decide how the school's money is to be spent (e.g. school maintenance, the hiring of additional teachers and other staff, the buying of books and equipment, and the power to exercise influence over the hiring and disciplining of teachers). The system is unique among state- aided schools in that Model Cs are all former state schools in the privileged white school system. Nearly all inherited a sound infrastructure provided largely by the state in the form of school buildings, grounds, libraries, laboratories etc. They also inherited a well qualified teaching staff, whose training (the best in the country) was also partly the result of public subsidies. Model C has several strengths which has led to the ongoing controversy. Parental participation in the schooling of their children has been mobilised. The governing bodies actually have power over important aspects of the school in contrast to the old comparatively toothless management councils. This, it appears, has ensured that parents, whether they approve of Model C or not, take them much more seriously since the governing bodies can take decisions which materially affect them and their children's education. In addition, this model has mobilised private resources for education and ensured that a relatively high level of provision can be maintained while state funding is decreased. Money thus saved by the state - reportedly about R1 billion - can be diverted to redressing the inadequacies of African education.

- Description: Ethnopharmacological relevance Tetracera potatoria Afzel. Exg. Don (Dilleniaceae) is a medicinal plant used traditionally in Africa for the treatment of tuberculosis related ailments and respiratory infections. The antibacterial activity of the medium polar extracts of T. potatoria leaves and stem bark was recently reported against Mycobacterium smegmatis (MIC 25 µg/mL) and M. aurum (65 µg/mL), two fast-growing Mycobacterium strains used as model micro-organisms for the more pathogenic strain Mycobacterium tuberculosis (Fomogne-Fodjo et al., 2014). The aim of this study was consequently to isolate the compounds possibly contributing to this activity, and which may therefore be promising precursors to be used for the development of novel anti-TB drugs.

Psychotherapy for post-traumatic stress disorder in a young rape survivor: a case study

- Description: This paper describes the psychodynamic psychotherapy of a 20-year-old African woman with post-traumatic stress disorder (PTSD). ‘Mphumi’ entered therapy a year after her father’s friend had repeatedly raped her. The paper documents the process of therapy and uses the case material to examine theoretical issues relevant to the treatment of PTSD. First, Horowitz’s (2001) theory is used as a basis for arguing that a histrionic personality style predisposed her to an extreme degree of denial and dissociation, which prevented her from processing the trauma at a cognitive or emotional level and contributed to the entrenched PTSD. It was only after she had suffered a breakdown, which necessitated hospitalisation, that her resistance to processing the trauma was overcome. Second, the case material is used to show how other significantly disturbing events earlier in her life shaped her response to the rape and to examine the extent to which effective processing of the current trauma calls for the acknowledgement and working through of earlier traumas and losses. Finally, the case narrative shows how the treatment of PTSD is of necessity a slow, complex process which takes into account the individual’s unique history, idiosyncratic vulnerabilities and socio-cultural context

- Description: Months were spent researching and preparing this four-part series on the dramatic events surrounding NELSON MANDELA, the life-term prisoner who has cast a larger than life shadow on South African politics. Staff writer DENNIS CRUYWAGEN travelled extensively to interview at first hand — or by other means, where necessary — those stalwart ANC veterans who were convicted in the Rivonia Treason Trial and jailed with Mandela. He talked, too, to members of the Mandela family, politicians, lawyers and many others who were close to or knowledgeable about the ANC leader. Official records and other sources on the life and times of Nelson Mandela were also consulted. Compiling the vast amount of information sometimes led to unusual situations. For instance, Mrs Winnie Mandela, always pressed for time, was interviewed — not in her home in Diepkloof, Soweto, as arranged but in a hired car in a Johannesburg traffic jam while following a vehicle driven by her driver. She was late for another appointment. Drawn from various sources this series sets out to reconstruct an overview of 25 years and more of political and personal drama, passion and poignancy. , Supplement to The Argus, Tuesday February 6 1990 , Exclusive Part 1

- Description: We herein report five different types of thiol dual capped cadmium tellurite quantum dots (CdTe QDs) namely glutathionemercapto-propanoic acid (QD 1), glutathione-thiolglycolic acid (QD 2), L-cysteine-mercapto-propanoic acid (QD 3), L-cysteinethiol-glycolic acid (QD 4) and mercapto-propanoic acid-thiol-glycolic (QD 5). Dual-capped CdTe QDs were prepared using a one pot synthetic method. Cadmium acetate and sodium tellurite were respectively used as cadmium and tellurium precursors. Photo-physical properties of the synthesized QDs were examined using UV-Vis and photoluminescence spectroscopy while structural characterization was performed by means of transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) spectroscopy.

Heat shock proteins as modulators and therapeutic targets of chronic disease: an integrated perspective

- Description: Many heat shock proteins (HSPs) are essential to survival as a consequence of their role as molecular chaperones, and play a critical role in maintaining cellular proteostasis by integrating the fundamental processes of protein folding and degradation. HSPs are arguably among the most prominent classes of proteins that have been broadly linked to many human disorders, with changes in their expression profile and/or intracellular/extracellular location now being described as contributing to the pathogenesis of a number of different diseases. Although the concept was initially controversial, it is now widely accepted that HSPs have additional biological functions over and above their role in proteostasis (so-called ‘protein moonlighting’).
