    Lind, G.H.; Phillips, H.R. [University of Witwatersrand, Johannesburg (South Africa)

    2001-06-01

    South Africa is a significant contributor to southern Africa and Europe's coal needs and is expected to remain in this important position for the foreseeable future. This review paper of the South African coal mining industry highlights that, although abundant, the easily mineable reserves will become depleted within the next quarter century. Socio-economic issues of unique, local importance such as the HIV/AIDS pandemic as well as policies propagated by South Africa's post-apartheid government are detailed, as are programmes in research and development that will ensure that South Africa's long term coal industry is, at the every least, maintained. 11 refs., 9 figs., 7 tabs.

  5. An example of change - the end of apartheid in the South African coal industry

    Energy Technology Data Exchange (ETDEWEB)

    1989-01-01

    This publication reports on a visit by four British MPs to the South African Coal Industry (SACI), made under the auspices of the SACI Committee which represents all the major coal exporting companies of South Africa. It is a private industry which operates independently of both the Government and the Chamber of Mines and does not benefit from any Government Subsidies. The aim of the visit was to investigate the SACI against a background of international pressure against an industry which appears to be a major example of change in South Africa. The visit programme included presentations on the South African coal industry in general, industrial relations and safety and research in the mining industry. Visits were made to both an underground mine and an opencast mine, a collieries training college, hospital, school, mine village and a coal terminal. At the end of the visit the delegation drew the conclusions that the South African coal industry is now organised on a totally non-discriminatory basis, offering employment and promotion opportunities to all workers regardless of their race and that there is therefore no justification for singling out this industry as a victim of sanctions policy.

    2004-10-01

    This study, the first to document the prevalence of pneumoconiosis among a living South African coal mining cohort, describes dose-response relationships between coal workers' pneumoconiosis and respirable dust exposure, and relationships between pneumoconiosis and both lung function deterioration and respiratory symptoms. A total of 684 current miners and 188 ex-miners from three bituminous-coal mines in Mpumalanga, South Africa, was studied. Chest radiographs were read according to the International Labour Organization (ILO) classification by two experienced readers, one an accredited National Institute for Occupational Safety and Health (NIOSH) "B" reader. Interviews were conducted to assess symptoms, work histories (also obtained from company records), smoking, and other risk factors. Spirometry was performed by trained technicians. Cumulative respirable dust exposure (CDE) estimates were constructed from historical company-collected sampling and researcher-collected personal dust measurements. kappa-Statistics compared the radiographic outcomes predicted by the two readers. An average profusion score was used in the analysis for the outcomes of interest. Because of possible confounding by employment status, most analyses were stratified on current and ex-miner status. The overall prevalence of pneumoconiosis was low (2%-4%). The degree of agreement between the two readers for profusion was moderate to high (kappa=0.58). A significant association (Pminers only. A significant (Pminers with pneumoconiosis than among those without. Logistic regression models showed no significant relationships between pneumoconiosis and symptoms. The overall prevalence of pneumoconiosis, although significantly associated with CDE, was low. The presence of pneumoconiosis is associated with meaningful health effects, including deterioration in lung function. Intervention measures that control exposure are indicated, to reduce these functional effects.

  12. The South African coal mining industry: A need for a more efficient and collaborative supply chain

    Directory of Open Access Journals (Sweden)

    David Pooe

    2011-11-01

    Full Text Available It is estimated that about two-thirds of global coal is used for power generation and that, in the next 20 years, over 70% of the demand for coal will come from China and India. Coal accounts for approximately 41% of the world's electricity generation. Demand for thermal coal is influenced by factors that include availability, prices of competing products such as oil, gas and nuclear power, and the demand for electricity. The aim of this article is to provide an exposition of supply chain dynamics within the South African coal mining industry and to argue for a more efficient and collaborative supply chain. The authors attempt to investigate at local and global level, the current trends pertaining to the level of reserves, production and consumption of coal. The article further demonstrates the shortcomings of current logistics in meeting the demand for coal in both domestic and export markets. The article draws from secondary data sourced from academic papers, government and agency documents in the exposition of the coal mining supply chain. The paper concludes by recommending the need for a scientific study on supply chain constraints facing the coal mining industry in South Africa.

  13. Views of coal miners in South Africa on sanctions

    Energy Technology Data Exchange (ETDEWEB)

    Puhe, H.; Schoeppner, K.P.

    1987-01-01

    Presents the results of a survey conducted during 1987, of the attitudes of a sample of black, male coal miners working in 6 export-orientated mines in Transvaal and 3 in Natal. Both mines and miners were selected at random and nearly 1,000 interviews were conducted. The most significant findings are as follows: South African coal miners are largely satisfied with their conditions of work, above all with social benefits, safety standards and the relations amongst the workers themselves. Regarding improvements in their working conditions miners attach by far the greatest importance to the question of wages. Next on the list are improvements in accomodation and the abolition of apartheid. The issue of 'sanctions' is not debated very widely. More than two-thirds of polled miners had not heard of sanctions previously. Nevertheless, after an explanation of what the term means, a large majority of South African coal miners (70%) rejects sanctions. Only one-fifth (21%) is for sanctions. Three-quarters of miners polled believe that sanctions would hit them hard. Above all they mentioned the risk of losing their jobs (79%), life at home (75%) and a decline in wages (74%). 34% of coal miners would support sanctions if they were ultimately to lead to the fall of the South African Government. 26% if sanctions were to lead to the fall of the South African Government, but also to a loss of their own jobs. Most of the miners polled felt that the trade unions were representing them well. However, South African coal miners are insufficiently informed on supposed positions adopted by the trade unions on separate issues and this applies to trade union policy on sanctions as well. 72% of miners polled seek a government that shares power equally between black and white. Moderate means are proposed to attain such a government. Only a minority, the hard core comprising about 25% of the South African miners, seeks violent confrontation.

    2017-10-01

    Key characteristics of coal samples from the supply stock to the newly commissioned South African National Power Utility's (Eskom's) Medupi Power Station - which receives its supply coal from the Waterberg coalfield in Lephalale (Limpopo Province, South Africa) - were evaluated. Conventional coal characterisation such as proximate and ultimate analysis as well as determination of sulphur forms in coal samples were carried out following the ASTM and ISO standards. Coal was classified as medium sulphur coal when the sulphur content was detected in the range 1.15-1.49 wt.% with pyritic sulphur (≥0.51 wt.%) and organic sulphur (≥0.49 wt.%) accounted for the bulk of the total sulphur in coal. Maceral analyses of coal showed that vitrinite was the dominant maceral (up to 51.8 vol.%), whereas inertinite, liptinite, reactive semifusinite and visible minerals occurred in proportions of 22.6 vol.%, 2.9 vol.%, 5.3 vol.% and 17.5 vol.%, respectively. Theoretical calculations were developed and used to predict the resultant SO 2 emissions from the combustion of the Waterberg coal in a typical power plant. The sulphur content requirements to comply with the minimum emissions standards of 3500 mg/Nm 3 and 500 mg/Nm 3 were found to be ≤1.37 wt.% and ≤0.20 wt.%, respectively.

    2007-07-02

    The binderless briquetting of some selected South African prime coking and blend coking coals, as well as the effects of weathering on the binderless briquetting of some inertinite-rich bituminous coals, were investigated in the laboratory. Selected properties of these coals were determined and the coals were briquetted at various moisture contents and pressures. Based on the results obtained in this study, binderless briquetting was found to be most successful in the cases of the fresh, vitrinite-rich coking and blend coking coals and satisfactory in the fresh inertinite-rich Witbank coals. However, the bonding process seemed to be adversely affected by weathering. The negative impact on bonding could be ameliorated to some extent by the presence of a significant kaolinite content when the percentage ash reports in the order of more than 15% (air-dry basis). It should, however, be noted that kaolinite may reduce the water resistance of the briquettes. (author)

  18. Study on surface morphology and physicochemical properties of raw and activated South African coal and coal fly ash

    Science.gov (United States)

    Mishra, S. B.; Langwenya, S. P.; Mamba, B. B.; Balakrishnan, M.

    South African coal and coal fly ash were selected as the raw materials to be used for study of their morphology and physicochemical properties and their respective activated carbons for adsorption applications. Coal and fly ash were individually steam activated at a temperature range of 550-1000 °C for 1 h in a muffle furnace using cylindrical stainless steel containers. Scanning electron micrographs revealed a change in surface morphology with more mineral matter available on the surface of the coal particles due to increased devolatilization. However, in the case of fly ash, the macerals coalesced to form agglomerates and the presence of unburnt carbon constituted pores of diameter between 50 and 100 nm. The BET surface area of coal improved significantly from 5.31 to 52.12 m 2/g whereas in case of fly ash the surface area of the raw sample which was originally 0.59 m 2/g and upon activation increased only up to 2.04 m 2/g. The chemical composition of the fly ash confirmed that silica was the major component which was approximately 60% by weight fraction. The impact of this study was to highlight the importance of using raw materials such as coal and a waste product, in the form of coal ash, in order to produce affordable activated carbon that can be used in drinking water treatment. This would therefore ensure that the quality of water supplied to communities for drinking is not contaminated especially by toxic organic compounds.

    The South African government has started a low-smoke coal programme to reduce air pollution from combustion of coal, which is used for cooking and heating in some residential areas despite electrification. Government policy is to assist the private sector to manufacture and market low-smoke fuels and to encourage use of cleaner fuels. The philosophy and the implementation of this programme are discussed. Preliminary results from a macro scale experiment, that involved supplying low-smoke fuel to a township for a period of one to two weeks and monitoring the impacts, are reported.

  20. Structural elucidation, molecular representation and solvent interactions of vitrinite-rich and inertinite-rich South African coals

    Science.gov (United States)

    van Niekerk, Daniel

    The structural differences and similarities of two Permian-aged South African coals, vitrinite-rich Waterberg and inertinite-rich Highveld coals (similar rank, carbon content and Permian age), were evaluated. With South African coals the opportunity presented itself to study not only Permian-aged Gondwana vitrinite but also inertinite. It was expected that these coals would differ from Northern hemisphere Carboniferous coals. It was concluded from various structural data that both coals, although different in maceral composition and depositional basins, are similar in their base structural composition. The main differences were that the inertinite-rich Highveld coal was more ordered, more aromatic, and had less hydrogen than the vitrinite-rich Waterberg coal. Analytical data were used to construct large-scale advanced molecular representations for vitrinite-rich Waterberg and inertinite-rich Highveld coals. The three-dimensional models were structurally diverse with a molecular weight range of 78 to 1900 amu. The vitrinite-rich coal model consisted of 18,572 atoms and 191 individual molecules and the inertinite-rich coal model consisted of 14,242 atoms and 158 individual molecules. This largescale modeling effort was enabled by the development of various PERL scripts to automate various visualization and analytical aspects. Coal swelling studies were conducted using the traditional pack-bed swelling method and a new novel single-particle stop-motion videography swelling method with NMP and CS2/NMP solvents. The pack-bed swelling showed that vitrinite-rich coal had a greater swelling extent and that swelling extent for both coals was greater in CS2/NMP binary solvent than for NMP. Single-particle swelling experiments showed that both coals, for both solvents, exhibit overshoot-type and climbing-type swelling behaviors. Inertinite-coal had a faster swelling rate, in both solvents, than the vitrinite-rich coal. The single-particle swelling data was used to calculate

  1. Nuclear power more profitable than coal if funded with low cost capital: A South-African case study

    International Nuclear Information System (INIS)

    Serfontein, Dawid E.

    2014-01-01

    This study summarizes and expands on economic simulation results from the author’s reviews of the South-African Government’s Draft Integrated Energy Plan (IEP) and Integrated Resource Plan Update 2013 (IRP Update). The Levellized Cost of Electricity (LCOE), as a function of the pre-tax Weighted Average Cost of Capital (WACC%) and the pre-tax % rate of return and the pre-tax nominal profit per unit power sold (R/kWh), as a function of the electricity selling price, are compared for a new Generation III nuclear plant and a new pulverized coal plant with Flue Gas Desulphurization (FGD), built in South Africa. All monetary amounts are expressed in constant real 2012 South African Rand (R), i.e. inflation has been removed. An exchange rate of R8.01/$ was assumed. Since the key economic features of HTRs and Generation III water-cooled nuclear plants are similar, e.g. high initial capital cost followed by low fuel and other variable costs and long plant lives, these results for Generation III nuclear plants are also applicable to HTRs. The results show that the LCOE for nuclear increases sharply with the pre-tax WACC%. For low WACC percentages, nuclear power is much cheaper than coal and vice versa. However the pre-tax nominal profit per unit nuclear power sold (R/kWh) greatly outperforms coal for all values of the electricity selling price, even if the nuclear overnight cost increases to the much maligned $7,000/kW-installed. Especially impressive is the result that nuclear already breaks even at R 0.30/kWh while coal will run at a loss until the price is increased to R 0.68/kWh. This result, that nuclear produces the most profitable power of all readily available sources in South Africa, implies the following power plant construction strategy: Supply the minimum expected new base-load with nuclear plants, augmented by peaking plants, such as hydro and gas turbine in order to balance the constant base-load power supply with the varying demand during different times

    2014-08-01

    Carbon nanofibers (CNFs), cylindrical nanostructures containing graphene, were synthesized directly from South African fly ash (a waste product formed during the combustion of coal). The CNFs (as well as other carbonaceous materials like carbon nanotubes (CNTs)) were produced by the catalytic chemical vapour deposition method (CCVD) in the presence of acetylene gas at temperatures ranging from 400°C to 700°C. The fly ash and its carbonaceous products were characterized by transmission electron microscopy (TEM), thermogravimetric analysis (TGA), laser Raman spectroscopy and Brunauer-Emmett-Teller (BET) surface area measurements. It was observed that as-received fly ash was capable of producing CNFs in high yield by CCVD, starting at a relatively low temperature of 400°C. Laser Raman spectra and TGA thermograms showed that the carbonaceous products which formed were mostly disordered. Small bundles of CNTs and CNFs observed by TEM and energy-dispersive spectroscopy (EDS) showed that the catalyst most likely responsible for CNF formation was iron in the form of cementite; X-ray diffraction (XRD) and Mössbauer spectroscopy confirmed these findings.

    2006-06-15

    Dose-response associations between respirable dust exposure and respiratory symptoms and between symptoms and spirometry outcomes among currently employed and formerly employed South-African coal miners were investigated. Work histories, interviews, and spirometry and cumulative exposure were assessed among 684 current and 212 ex-miners. Results: Lower prevalences of symptoms were found among employed compared with ex-miners. Associations with increasing exposure for symptoms of phlegm and past history of tuberculosis were observed, whereas other symptom prevalences were higher in the higher exposure categories. Symptomatic ex-miners exhibited lower lung-function compared to the nonsymptomatic. Compared with published data, symptoms rates were low in current miners but high in ex-miners. Although explanations could include the low prevalence of smoking and/or reporting/selection bias, a 'Survivor' and/or a 'hire' effect is more likely, resulting in an underestimation of the dust-related effect.

    1998-09-01

    The South Blackwater operation consists of two opencut mining areas and two underground mines (Laleham and Kenmure) near Blackwater in central Queensland, all of which supply coal to a central coal preparation plant. South Blackwater Coal Ltd. recently developed a maintenance improvement programme, described in this article. The programme involved implementation systems of key performance indicators (KPIs), benchmaking, condition monitoring, work planning and control, failure analysis and maintenance audit. Some improvements became almost immediately apparent, others were quite gradual. Major results included: improved availability (and reliability) of all opencast fleets, improvements in rear dump availability; reduced maintenance man-hours for opencast fleets; and increased availability of the coal handling and preparation plant. The paper is an edited version of that presented at the `Maintenance in mining conference` 16-19 March 1998, held in Bali, Indonesia. 4 figs., 2 photos.

    1997-01-01

    Like China, a large portion of South Africa's primary energy is sourced from coal, and is likely to remain South Africa's major source of energy for the short to medium term. It is imperative to address the environmental dimension as an integral component of coal energy considerations. This issue is discussed through energy efficiency, and South Africa's Low-Smoke Coal Programme as it pertains to the use of coal in households. South Africa is engaged on several other programmes to minimise the impact of coal on the atmospheric environment. Some of those activities have been outlined in this paper. (R.P.)

  13. Distributional Fate of Elements during the Synthesis of Zeolites from South African Coal Fly Ash

    Directory of Open Access Journals (Sweden)

    Pieter W. Du Plessis

    2014-04-01

    Full Text Available The synthesis of zeolites from South African coal fly ash has been deemed a viable solution to the growing economical strain caused by the disposal of ash in the country. Two synthesis routes have been studied thus far namely the 2-step method and the fusion assisted process. Fly ash contains several elements originating from coal which is incorporated in the ash during combustion. It is vital to determine the final destination of these elements in order to unveil optimization opportunities for scale-up purposes. The aim of this study was to perform a material balance study on both synthesis routes to determine the distributional fate of these elements during the synthesis of zeolites. Zeolites were first synthesized by means of the two synthesis routes. The composition of all raw materials and products were determined after which an overall and elemental balance were performed. Results indicated that in the 2-step method almost all elements were concentrated in the solid zeolite product while during the fusion assisted route the elements mostly report to the solid waste. Toxic elements such as Pb, Hg, Al, As and Nb were found in both the supernatant waste and washing water resulting from each synthesis route. It has also been seen that large quantities of Si and Al are wasted in the supernatant waste. It is highly recommended that the opportunity to recycle this liquid waste be investigated for scale-up purposes. Results also indicate that efficiency whereby Si and Al are extracted from fused ash is exceptionally poor and should be optimized.

  17. Aspects of the environmental geology of coal extraction in South Africa

    1996-01-01

    Existing areas of regulatory intervention in South Africa, related to coal extraction, are discard and stockpile burning (low level air pollution), acid rock drainage (water pollution) and landscape and mine rehabilitation. These impacts are managed in terms of the Minerals Act (No. 50 of 1991) and its subsequent amendments. Exploration and mining companies (at any scale or size) are required to prepare Environmental Management Programme Reports (EMPR) in terms of existing legislation. The submission and approval of an EMPR results in site-specific legal obligations for which the mining company must make pecuniary provision. Individual coal producers have led the mining industry in the establishment of trusts to fund such rehabilitation. River catchment areas in the Mpumalanga Province and in northern KwaZulu Natal have suffered serious water quality deterioration as a result of polluted water emanating from abandoned coal mines. The relatively small household coal sector has health impacts out of proportion with its size, with the attendant increases in health risk clearly documented. Economic geologists have been concerned with the proving of non-renewable resources and management and production of reserves once mining commences. Mining investment decisions are increasingly influenced by the necessity to rehabilitate mined out areas and manage environmental impact. Understanding potential cost, at the end of the mining project cycle is as significant as understanding the genesis or value of a deposit. Site specific examples of typical South African problems will be presented

  18. An overview of coal preparation initiatives with application to coal conversion in South Africa

    Coal has for many years been the most important energy resource in South Africa and has contributed to more than 70 % of South Africa's energy needs in 1998. The large in-situ coal deposits (in excess of 120 x 10 9 t) and relatively large recoverable reserves (about 33.5 x 10 9 t) will ensure that coal will for many a year still be South Africa's single biggest energy resource. Biomass burning consumes approximately 11 Mt/a of which 8 Mt/a is natural wood. This equals natural wood production. The use of firewood is considered to be unsustainable. Of the 225 Mt/a of coal extracted in South Africa in 1998, 67.0 Mt/a was exported. Of this, 62.9 Mt/a were exported as steam coal, 2.1 Mt/a as metallurgical coal, and the rest as anthracite. Current exports are conducted via the Richards Bay terminal (63.6 Mt/a), Durban (2.0 Mt/a) and a small amount via Maputo. The Richards Bay terminal is to be expanded to 72 Mt/a by 1999. It is also very important to note that most of the coal resources possess calorific values of below 25 MJ/kg, which limits its utilization to power generation (Eskom) and processes such as fixed bed dry bottom gasification (Sasol). A break-down of production and usage of coal by the various controlling groups in South Africa shows that Sasol (54.2 Mt/a) and Escom (91.0 Mt/a) are major consumers of coal. It has been proposed earlier by Horsfall (1993) that for power generation and coal conversion, the in-situ quality is generally regarded as satisfactory for use. All that is required in the way of processing is crushing to an appropriate top size and, for conversion, screening of the unwashed coal. Most other consumers require some degree of beneficiation, which generally entails the removal of stone/shale and low quality coal. More recently, the introduction of destoning plants at Duvha Colliery (Larcodems) and New Vaal Colliery (Drewboy washers) has significantly reduced the abrasiveness content of these local thermal coals, together with an increase

  19. The occurrence of potentially hazardous trace elements in five Highveld coals, South Africa

    Permian coals of the southern hemisphere are generally considered to contain lower concentrations of sulfides, halogens, and trace elements when compared to northern hemisphere Carboniferous coals. Few studies have considered the trace element content in South African coals, and little or no work has been published for Highveld coals. Of the nineteen coal fields in South Africa, the Highveld coal field is one of the nine currently producing, and is second largest in terms of production. Five run of mine samples and a high ash middlings product from the Number 4 Lower seam were analyzed, totaling six sample sets. Fourteen trace elements (As, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Se, V, and Zn) were selected for this study based on the global perception that these elements may be hazardous to human health and/or the environment when they are released during coal utilization. Several sample preparation techniques were tested using certified reference materials (SARMs 18, 19 and 20) to determine the most repeatable technique for these coals. The samples were analyzed by ICP-AES and CVAA (Hg only). Microwave digestion proved to be generally unreliable despite the utilization of several different methods. A slurry direct injection method into the ICP-AES provided good correlations with the reference material, but requires further development to enhance the confidence level in this relatively unexplored technique. Samples prepared based on three ASTM standards for the determination of trace elements in coal provided repeatable results in most instances, and were the preparation methods utilized for the Highveld coals. The trace element values determined for the Highveld coals are generally in good agreement with values available in literature for South African coals, with the exception of Hg, Mn and Cr. Hg values reported here are lower, Cr and Mn higher. Results generally agree well with analyses on the same samples conducted by the United States Geological Survey

    This paper explores the effects of financial development, economic growth, coal consumption and trade openness on environmental performance using time series data over the period 1965–2008 in case of South Africa. The ARDL bounds testing approach to cointegration has been used to test the long run relationship among the variables while short run dynamics have been investigated by applying error correction method (ECM). The unit root properties of the variables are examined by applying Saikkonen and Lütkepohl (2002. Econometric Theory 18, 313–348) structural break unit root test. Our findings confirmed long run relationship among the variables. Results showed that a rise in economic growth increases energy emissions, while financial development reduces it. Coal consumption has significant contribution to deteriorate environment in South African economy. Trade openness improves environmental quality by reducing the growth of energy pollutants. Our empirical results also verified the existence of environmental Kuznets curve. This paper opens up new insights for South African economy to sustain economic growth by controlling environment from degrdation through efficient use of energy. - Highlights: • We found that a rise in economic growth increases energy emissions. • We found that financial development lowers energy emissions. • We found that coal consumption significantly deteriorate environment. • We found that trade openness improves environmental quality. • Existence of EKC is also found

  1. Estimation of respirable dust exposure among coal miners in South Africa.

    The use of retrospective occupational hygiene data for epidemiologic studies is useful in determining exposure-outcome relationships, but the potential for exposure misclassification is high. Although dust sampling in the South African coal industry has been a legal requirement for several decades, these historical data are not readily adequate for estimating past exposures. This study describes the respirable coal mine dust levels in three South African coal mines over time. Each of the participating mining operations had well-documented dust sampling information that was used to describe historical trends in dust exposure. Investigator-collected personal dust samples were taken using standardized techniques from the face, backbye (underground jobs not at the coal face), and surface from 50 miners at each mine, repeated over three sampling cycles. Job histories and exposure information was obtained from a sample of 684 current miners and 188 ex-miners. Linear models were developed to estimate the exposure levels associated with work in each mine, exposure zone, and over time using a combination of operator-collected historical data and investigator-collected samples. The estimated levels were then combined with work history information to calculate cumulative exposure metrics for the miner cohort. The mean historical and investigator-collected respirable dust levels were within international norms and South African standards. Silica content of the dust samples was also below the 5% regulatory action level. Mean respirable dust concentrations at the face, based on investigator-collected samples, were 0.9 mg/m(3), 1.3 mg/m(3), and 1.9 mg/m(3) at Mines 1, 2, and 3, respectively. The operator-collected samples showed considerable variability across exposure zones, mines, and time, with the annual means at the face ranging from 0.4 mg/m(3) to 2.9 mg/m(3). Statistically significant findings were found between operator- and investigator-collected dust samples. Model

    Mercury (Hg) analyses were obtained for 42 samples of feed coal provided by Eskom, the national electric utility of South Africa, representing all 13 coal-fired power stations operated by Eskom in South Africa. This sampling includes results for three older power stations returned to service starting in the late 2000s. These stations were not sampled in the most recent previous study. Mercury concentrations determined in the present study are similar to or slightly lower than those previously reported, and input Hg for the three stations returned to service is comparable to that for the other 10 power stations. Determination of halogen contents of the 42 feed coals confirms that chlorine contents are generally low, and as such, the extent of Hg self-capture by particulate control devices (PCDs) is rather limited. Eight density separates of a South African Highveld (#4) coal were also provided by Eskom, and these show a strong mineralogical association of Hg (and arsenic) with pyrite. The density separates were used to predict Hg and ash contents of coal products used in South Africa or exported. A suite of 48 paired samples of pulverization-mill feed coal and fly ash collected in a previous (2010) United Nations Environment Programme-sponsored study of emissions from the Duvha and Kendal power stations was obtained for further investigation in the present study. These samples show that in each station, Hg capture varies by boiler unit and confirms that units equipped with fabric filters for air pollution control are much more effective in capturing Hg than those equipped with electrostatic precipitators. Apart from tracking the performance of PCDs individually, changes resulting in improved mercury capture of the Eskom fleet are discussed. These include Hg reduction through coal selection and washing, as well as through optimization of equipment and operational parameters. Operational changes leading to increased mercury capture include increasing mercury

  4. Preliminary investigation of predictors of the cutting forces for some South African coals

    This paper discusses the possible use of petrological data and proximate analyses in the prediction of cutting forces for coal. It is restricted to the development of univariate predictors based on data from thirteen collieries in five major Transvaal and Orange Free State coalfields and three coal provinces. The aim of the work was the identification and development of the best predictors of mean peak cutting force and Hardgrove grindability index from among the independent variables evaluated. The data were processed according to the SPSS computer package. The analysis revealed reasonable correlations between the Hardgrove grindability index and (1) the volatiles and vitrinite content in the Vereeniging-Sasolburg and South Rand Coalfields, (2) the contents of vitrinite, vitrinite plus exinite, and minerals plus inertinite in the Eastern Transvaal Coalfield.

  10. The power vacuum: the effect of the electricity power crisis on GDP in South Africa in the context of an uncertain coal supply.

    Energy Technology Data Exchange (ETDEWEB)

    Sorensen, P. [Freyaafdrammen (South Africa)

    2011-07-01

    In 1988 the South African government released a white paper advocating an increased electricity supply to meet social obligations. Large sectors of the rural population in South Africa were not electrified. The National Electrification Program (NEP) was launched in 1994 to wipe out the electrification backlog by 2012. The target of the first phase of NEP was achieved. By 2003, a basic 50kWh electricity per month was supplied free of charge, due to the poverty of the population. In 1996, the GEAR (Growth, Employment and Redistribution) strategy was introduced to generate 6% GDP growth, create 400,000 new jobs each year and increase foreign investment. But the race for GDP growth could result in high electricity consumption and frequent interruptions, particularly in energy-intensive industries which had been introduced in South Africa. The national coal production rate has been reached and surpassed its peak, leading to the end of the cheap coal era in South Africa but more expensive coal could slow down industrial development.

  11. Carbon Risk Analysis Of The South African Banks’ Lending To The JSE100 CDP Companies

    Directory of Open Access Journals (Sweden)

    Alfred Bimha

    2015-11-01

    Full Text Available There is a pertinent concern over the continued lending to companies that are still pursuing projects that increase the amount of carbon emissions in the atmosphere. South Africa has most of its energy generation being done through coal thermal powered turbines. More so there are a number of new power stations being built in South Africa that are coal powered. Coal on the other hand is deemed as having the highest amount of carbon that contributes to the greenhouse effect which in turn affects the climate leading to climate change consequences. There is also a growing concern on the uptake of renewable energy initiatives by companies that are deemed carbon intensive. Banks are being castigated for not using their economic transformation role to champion the agenda of combating climate change caused by carbon emissions. In this study, the extent of lending in the short and long term to carbon intensive companies by South African banks is examined. Using a sample of the Johannesburg Stock Exchange top 100 companies that participate in Carbon Disclosure Project, an analysis is done through four carbon metrics –carbon intensity, carbon dependency, carbon exposure, carbon risk. The analysis used public information from the banks’ websites, South African Reserve Bank reports and other public databases that contain sustainability information of the JSE100 companies. The analysis was done by comparing the carbon metrics of the recognized seven (7 sectorial industry catergories (SIC on the JSE, mainly Energy & Materials, Industrials, Consumer Staples, Consumer Discretionary, Financials, IT & Telecoms and Health Care. The major finding of the research is that there is a high carbon risk in short term loans compared to long term loans across the JSE100 companies that are analysed. More so, the Energy & Materials sector seem to have the highest carbon risk compared to the other sectors.

  7. 5-HTTLPR Polymorphism: Analysis in South African Autistic Individuals

    KAUST Repository

    2010-06-01

    The serotonin transporter promoter length polymorphism (5-hydroxytryptamine transporter length polymorphism; 5-HTTLPR) has long been implicated in autism and other psychiatric disorders. The use of selective serotonin reuptake inhibitors (SSRIs) has a positive effect on treating some symptoms of autism. The effects of these drugs vary in individuals because of the presence of the S or L allele of 5-HTTLPR. Studies performed on various autistic populations have found different allele frequencies for the L and S alleles. Allele frequencies and genotypes of the South African autistic populations (African, mixed, and Caucasian) were compared with matching South African ethnic control populations. The *S/*S genotype was found to be highly significantly associated with all the South African autistic ethnic populations. In the South African African population the *S/*S genotype was present in 7 (33%) of the autistic individuals but in none of the control subjects, yielding infinitely large odds of developing autism. The odds of developing autism with the *S/*S genotype compared to the *L/*L genotype increased 10.15-fold in the South African mixed group and 2.74-fold in the South African Caucasian population. The allele frequency of the South African autistic population was also compared with studies of other autistic populations around the world, and highly significant differences were found with the Japanese, Korean, and Indian population groups. The difference was not significant for the French, German, Israeli, Portuguese, and American groups. This is the first South African study of autistic individuals of different ethnic backgrounds that shows significant differences in allele and genotype frequencies of 5-HTTLPR. The results of this study open new avenues for investigating the role of transmission of the L and S alleles in families with autism in South Africa.

  10. Review of carbon dioxide capture and storage with relevance to the South African power sector

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available Carbon dioxide (CO2 emissions and their association with climate change are currently a major discussion point in government and amongst the public at large in South Africa, especially because of the country's heavy reliance on fossil fuels for electricity production. Here we review the current situation regarding CO2 emissions in the South African power generation sector, and potential process engineering solutions to reduce these emissions. Estimates of CO2 emissions are presented, with the main sources of emissions identified and benchmarked to other countries. A promising mid-term solution for mitigation of high CO2 emissions, known as CO2 capture and storage, is reviewed. The various aspects of CO2 capture and storage technology and techniques for CO2 capture from pulverised coal power plants are discussed; these techniques include processes such as gas absorption, hydrate formation, cryogenic separation, membrane usage, sorbent usage, enzyme-based systems and metal organic frameworks. The latest power plant designs which optimise CO2 capture are also discussed and include integrated gasification combined cycle, oxy-fuel combustion, integrated gasification steam cycle and chemical looping combustion. Each CO2 capture technique and plant modification is presented in terms of the conceptual idea, the advantages and disadvantages, and the extent of development and applicability in a South African context. Lastly, CO2 transportation, storage, and potential uses are also presented. The main conclusions of this review are that gas absorption using solvents is currently most applicable for CO2 capture and that enhanced coal bed methane recovery could provide the best disposal route for CO2 emissions mitigation in South Africa.

  13. The Environmental Mitigation Potential of Photovoltaic-Powered Irrigation in the Production of South African Maize

    Directory of Open Access Journals (Sweden)

    Sarah Wettstein

    2017-09-01

    Full Text Available Agriculture is under pressure to reduce its environmental impact. The use of renewable energy sources has potential to decrease these impacts. Maize is one of the most significant crops in South Africa and approximately 241,000 hectares are irrigated. This irrigation is most commonly powered by grid electricity generated using coal. However, South Africa has high solar irradiation, which could be used to generate photovoltaic electricity. The aim of this study was to determine the environmental mitigation potential of replacing grid-powered irrigation in South African maize production with photovoltaic irrigation systems using Life Cycle Assessment. The study included the value chain of maize production from cultivation to storage. Replacing grid electricity with photovoltaic-generated electricity leads to a 34% reduction in the global warming potential of maize produced under irrigation, and—applied at a national level—could potentially reduce South Africa’s greenhouse gas emissions by 536,000 t CO2-eq. per year. Non-renewable energy demand, freshwater eutrophication, acidification, and particulate matter emissions are also significantly lowered. Replacing grid electricity with renewable energy in irrigation has been shown to be an effective means of reducing the environmental impacts associated with South African maize production.

  13. SADCC: challenging the "South African connection.".

    Science.gov (United States)

    Liebenow, J G

    1982-01-01

    The Southern African Development Coordination Conference (SADCC) which unites 9 states with a combined population of 60 million, has as its objective the task of promoting economic development and realizing economic independence. In many respects the strain of neocolonialism that Southern Africa faces at this time is even more virulent than that facing West, Central, and East Africa. In the latter regions the surrender of political authority by colonial administrators frequently left the commercial, agricultural, and industrial interests of the European powers in continued control of the economies of the former colonies. The fate of economic development plans was determined by situations and decisions made in places distant from the African continent. In the case of Southern Africa, the withdrawal or expulsion of European colonialists has found whites in neighboring South Africa most eager to step into the economic breech. For most of the Southern African states this variant strain of the neocolonial virus creates a dual problem: the independent states acting separately have been no match for South Africa; and the acquiescence of independent African states in forging economic links with South Africa has impeded the liberation efforts of Africans in Namibia and the Republic of South Africa. Discussion focus turns to the challenges that confront SADCC; transport as the most significant factor accounting for the dependency of SADCC states upon South Africa; the role of minerals in dependency; other aspects of dependency; South Africa's proposed Constellation of States; the origins and objectives of SADCC; and dollars and donors. SADCC planning for economic liberation has been conducted against the background of a counterproposal advanced by South Africa's government, which put the Republic at the center of an expanded network of economic linkages within the entire southern African region. While being formally rejected, the Constellation of States scheme does have

  14. Brunel mood scale: South African norm study

    Directory of Open Access Journals (Sweden)

    Charles H Van Wijk

    2011-06-01

    Full Text Available Objective: The Brunel Mood Scale (BRUMS has proved useful to assess mood states in a range of clinical settings. Its local utility is restricted by the lack of normative data from South Africa. This paper presents preliminary normative data for the use of the BRUMS in the South African health care setting. Method: Participants (N=2200, ranging from 18 to 59 years, employed in the public sector, and were recruited during routine occupational health surveillance, completed the 24-item self-report BRUMS. They came from all South African race and language groups, and from all nine provinces. Results: Significant differences were found between the scores of women and men, and their results are reported separately. Due to the language dependant nature of the BRUMS, results are also reported separately for respondents with English as first language, and those who have other South African languages as mother tongue. Norm tables with T-scores are presented for the full sample, and per gender X language groups. Conclusion: This study presents normative data for a sample of educated and employed South Africans from various backgrounds. Its brevity, and provisionally language friendly nature makes it a useful measure for screening psychological distress in the SA clinical health care context.

  2. Darwin’s legacy in South African evolutionary biology

    Directory of Open Access Journals (Sweden)

    S. D. Johnson

    2010-02-01

    Full Text Available In the two decades after publication of the Origin of Species, Charles Darwin facilitated the publication of numerous scientific papers by settler naturalists in South Africa. This helped to establish the strong tradition of natural history which has characterised evolutionary research in South African museums, herbaria and universities. Significant developments in the early 20th century included the hominid fossil discoveries of Raymond Dart, Robert Broom, and others, but there was otherwise very little South African involvement in the evolutionary synthesis of the 1930s and 1940s. Evolutionary biology developed into a distinct discipline in South Africa during the 1970s and 1980s when it was dominated by mammalian palaeontology and a vigorous debate around species concepts. In the post-apartheid era, the main focus of evolutionary biology has been the construction of phylogenies for African plants and animals using molecular data, and the use of these phylogenies to answer questions about taxonomic classification and trait evolution. South African biologists have also recently contributed important evidence for some of Darwin’s ideas about plant–animal coevolution, sexual selection, and the role of natural selection in speciation. A bibliographic analysis shows that South African authors produce 2–3% of the world’s publications in the field of evolutionary biology, which is much higher than the value of about 0.5% for publications in all sciences. With its extraordinary biodiversity and well-developed research infrastructure, South Africa is an ideal laboratory from which to advance evolutionary research.

  5. Coal in sub-Saharan-African countries undergoing desertification

    Energy Technology Data Exchange (ETDEWEB)

    Weaver, J.N.; Brownfield, M.E.; Bergin, M.J. (United States Geological Survey, Denver, CO (USA))

    1990-01-01

    Coal has been reported in 11 of the 16 sub-Saharan countries discussed in this appraisal: Mauritania, Senegal, Mali, Niger, Benin, Nigeria, Cameroon, Central African Republic, Sudan, Ethiopia, and Somalia. No coal occurrences have been reported in Gambia, Togo, Burkina, Chad, and Djibouti but coal may be present within these countries because neighbouring countries do contain coal-bearing rocks. Most of these countries are undergoing desertification. Destruction of forest and shrub lands for fuel is occurring at an increasing rate because of desertification and increasing energy demands. Part of the present and future energy needs of the sub-Saharan region could be met by use of indigenous coal and peat. Nine sedimentary basins have the potential of either coal and/or peat deposits of economic value: 1- Senegal Basin, 2- Taoudeni Basin and Gao Trough, 3- Niger Basin, 4- Chad Basin. 5- Chari Basin, 6- Benue Trough (Depression), 7- Sudan Trough, 8- Plateau and Rift Belt, and 9- Somali Basin. Niger and Nigeria are the only countries in sub-Saharan Africa in which coal is presently being mined as a fuel source for powerplants and domestic use. Peat occurs in the deltas, lower river, and interdunal basin areas of Senegal, Mauritania, and Sudan. The overall objective of these studies is to establish, within the sub-Saharan region, energy independent countries using indigeneous coal and peat resources. These resources have the potential to replace wood and wood charcoal as domestic fuel in the urban centres, as well as producing electrical and industrial energy, thus reducing expensive oil imports and decreasing the rate of deforestation. 31 refs., 16 figs., 1 tab.

    1998-06-01

    A quantitative determination of the relative marcasite/pyrite contents in virgin coals is possible by means of {sup 57}Fe Moessbauer spectroscopy. Complications arise however, when iron-containing silicates, carbonates, or other salts are present. The application of a mild chemical treatment involving hydrofluoric acid has been employed to remove these Fe-containing phases while leaving the iron-disulfide phases unaffected. Several South African coal samples with non-iron disulfide, Fe-containing phases ranging from 18 to 30 weight percent were subjected to a hydrofluoric acid leaching at room temperature. The loss of mineral matter with HF leaching correlates well with the mineral matter residue following low temperature ashing. The {sup 57}Fe Moessbauer spectra of the resulting coal samples indicate that only FeS{sub 2} phases are present and the absence of appreciable quantities of marcasite in the coals.

  10. A new energy future for South Africa: The political ecology of South African renewable energy

    International Nuclear Information System (INIS)

    Krupa, Joel; Burch, Sarah

    2011-01-01

    Renewable energy remains a contested topic in South Africa. This paper argues that South Africa can build on the momentum surrounding its introduction of a feed-in tariff by enacting policies that may, if given adequate funding and political effort, allow the country to be a world leader in renewable energy. Given a variety of renewable energy policy options for moving forward, a majority of stakeholders consulted in this study strongly prefer the development of a renewable energy manufacturing cluster, in which government develops coordinated policy mechanisms that attract renewable energy manufacturers, over three other policies suggested by the authors. Interviews with key informants that play critical roles in this decision-making process suggest that there are reasons to remain cautiously optimistic about the country's renewable energy future while cognizant of the challenges that must still be overcome. Opportunities for a low carbon renewable energy transition in South Africa include the prevalence of broad stakeholder consultation, facilitated by civil society, and an innovative policy development context. Significant impediments also exist, however, and include pervasive social issues such as poverty and political inertia, along with the ongoing difficulties facing renewable energy technologies in reaching grid parity with inexpensive and abundant South African coal. - Highlights: → Numerous opportunities exist for a low carbon energy transition in South Africa. → Stakeholders in study prefer development of a renewable energy manufacturing cluster. → Significant impediments still exist, including grid parity, poverty, and inequality.

  17. African immigrants in South Africa: Job takers or job creators?

    Directory of Open Access Journals (Sweden)

    Vivence Kalitanyi

    2010-12-01

    Full Text Available During the last decade African immigrants have been met with and exposed to severe forms of hostility towards their presence in this country. A significant number of these migrants have successfully applied their entrepreneurial flair in establishing small enterprises and employing workers, often to the envy of their local counterparts. This paper presents the findings of an empirical study conducted in 2007 on job creation by African immigrant entrepreneurs for South Africans with face-to-face interviews with 120 African immigrant entrepreneurs. These findings were triangulated 7 non-governmental organisations that interact with immigrants in Cape Town. A review of the literature on migration, entrepreneurship and immigrant entrepreneurs formed the basis for the study The findings indicate that more than 80% of African immigrant entrepreneurs interviewed employ South Africans in their businesses. Despite a generally negative national perception towards immigrants, this study has also revealed that entrepreneurial skills are transferred from immigrant entrepreneurs to their South African employees. Whilst the study was only conducted in the suburban areas of Cape Town, the researcher believes that the results represent the general trend for South Africa. Furthermore, the study only involved those migrants who come from African continent. The overall result is the acknowledgement of the contribution that non-citizens are making to the country’s growth and development. The findings suggest recommendations geared towards policy changes regarding South African immigration law, an inclusive research about the role of immigrants on job creation in South Africa, as well as the consideration of immigrant entrepreneurs when allocating financial support.

  18. Disaster management and humanitarian logistics – A South African perspective

    Directory of Open Access Journals (Sweden)

    Wilna L. Bean

    2011-11-01

    Full Text Available Disasters are becoming an unavoidable part of everyday life throughout the world, including South Africa. Even though South Africa is not a country affected by large-scale disasters such as earthquakes, the impact of disasters in South Africa is aggravated significantly by the vulnerability of people living in informal settlements. Humanitarian logistics, as a ‘new’ sub-field in the supply chain management context, has developed significantly recently to assist in disaster situations. This paper provides an overview of the South African humanitarian logistics context. Even though humanitarian logistics plays a critical role in the aftermath of disasters, it extends far beyond events that can typically be classified as ‘disasters’. Therefore the implication of the South African humanitarian logistics context on future research and collaboration opportunities in South African humanitarian logistics is also discussed. Finally, two recent case studies in the South African humanitarian logistics environment are discussed.

    South Africa's academic publishing history has been profoundly influenced by its colonial heritage. This is reflected in the publication of Transactions of the South African Philosophical Society (later, the Royal Society of South Africa) from 1878. Although the Society and journal sought to promote original research about South Africa, it was modelled after the Royal Society in London and formed part of an imperial scientific community. As the local higher education institutions grew more independent and research-focused, local scholarly publishing developed as well, with university presses playing an increasingly important role. The University of South Africa (Unisa) Press started publishing departmental journals in the 1950s, with a focus on journals that ‘speak to the student’, and it is today the only South African university press with an active journals publishing programme. As external funding declined and the country became intellectually isolated in the high apartheid period, the Press managed to attract journals that could no longer be subsidized by learned societies and other universities. More recently, new co-publishing arrangements have brought South African journals back into an international intellectual community. Although some argue that this constitutes a re-colonization of South African knowledge production, it is also an innovative strategy for positioning local research in a global context. PMID:26495579

    Full Text Available Background: The South African property sector contributes highly to creating jobs, skills development, poverty reduction and economic growth. Although South Africa dropped in the global competitiveness ranking, the property sector of South Africa remains very competitive. To survive in a competitive sector, firms around the world practice competitive intelligence(CI. Although the use of CI has been examined in other sectors in South Africa, no study on CI practice has been conducted in the property sector. Objectives: The objective of this research was to establish the extent to which the property sector of South Africa practices CI. Method: This research was quantitative in nature and a web-based questionnaire was used to collect data from estate agencies in the South African property sector. Results: The results indicate that the South African property sector is very competitive and estate agencies practice CI to gain competitive advantage and make quality decisions.Moreover, the results reveal that the property sector practice CI legally and ethically. The results indicate that the majority of estate agencies are very small employing at most five employees and make at most 5 million Rands annual turnover. Conclusion: The South African property sector ethically and legally practices CI to gain competitive advantage and to aid in making quality decisions.

  8. Do the majority of South Africans regularly consult traditional healers?

    Directory of Open Access Journals (Sweden)

    Gabriel Louw

    2016-12-01

    Full Text Available Background The statutory recognition of traditional healers as healthcare practitioners in South Africa in terms of the Traditional Health Practitioners Act 22 of 2007 is based on various assumptions, opinions and generalizations. One of the prominent views is that the majority of South Africans regularly consult traditional healers. It even has been alleged that this number can be as high as 80 per cent of the South African population. For medical doctors and other health practitioners registered with the Health Professions Council of South Africa (HPCSA, this new statutory status of traditional health practitioners, means the required presence of not only a healthcare competitor that can overstock the healthcare market with service lending, medical claims and healthcare costs, but also a competitor prone to malpractice. Aims The study aimed to determine if the majority of South Africans regularly consult traditional healers. Methods This is an exploratory and descriptive study following the modern historical approach of investigation and literature review. The emphasis is on using current documentation like articles, books and newspapers, as primary sources to determine if the majority of South Africans regularly consult traditional healers. The findings are offered in narrative form. Results It is clear that there is no trustworthy statistics on the percentages of South Africans using traditional healers. A scientific survey is needed to determine the extent to which traditional healers are consulted. This will only be possible after the Traditional Health Practitioners Act No 22 has been fully enacted and traditional health practitioners have become fully active in the healthcare sector. Conclusion In poorer, rural areas no more than 11.2 per cent of the South African population regularly consult traditional healers, while the figure for the total population seems to be no more than 1.4 per cent. The argument that the majority of South

  10. Supplier–customer relationships: Weaknesses in south african automotive supply chains

    Directory of Open Access Journals (Sweden)

    M. J. Naude

    2012-11-01

    Full Text Available The South African automotive industry, which is an important sector in the South African economy, needs to function efficiently if it is to compete internationally. However, South African automotive components manufacturers (ACMs are not internationally competitive and automotive assemblers, also known as original equipment manufacturers (OEMs, often import cheaper components from abroad. All parties in the South African automotive supply chains need each other to ensure optimal efficiency and competitiveness. Furthermore, it is vital that good relationships exist between customers and suppliers in the automotive supply chains in South Africa. ACMs are central to automotive supply chains. A survey was conducted among ACMs to determine the nature of relationships that exist between buyers and suppliers in South Africa’s automotive supply chains. The results showed that collaborative relationships do indeed exist between members of the supply chain but that communication, understanding of the parties’ situations and cooperation can improve this relationship and so create total alliance between OEMs and ACMs.

    Presents the views of the South African National Union of Mineworkers on the role of coal mining in South Africa and future prospects for the industry. Coal is considered to be a vital component of the country`s post-apartheid economic and social reconstruction programme, being a major fuel for industry and power generation and a raw material for the chemical industry. The author calls for education and training for miners and improvements in health and safety.

  14. Chemical and mineralogical characterization of highly and less reactive coal from Northern Natal and Venda-Pafuri coalfields in South Africa

    Kataka, M. O.; Matiane, A. R.; Odhiambo, B. D. O.

    2018-01-01

    Spontaneous combustion of coal is a major hazard associated with the coal mining industry over centuries. It also a major cause of underground fires in South African collieries and in opencast operations, spoil heaps and stockpiles. Spontaneous combustion incidents are manifested in all major aspects of coal mining namely, underground mining, surface mining, including during sea-borne transportation, storage and waste disposal. Previous studies indicate that there are various factors (both intrinsic and extrinsic) that influence the spontaneous combustion of coals. This paper characterizes highly reactive coal from the Vryheid coalfields and less reactive coal from at Venda-Pafuri coalfield, to identify and delineate some intrinsic coal parameters that are considered to be most critical in terms of heat 'generation' and relationships between the two coals types by tracing their similarities and differences in their spontaneous combustion parameters. Various tests were carried out to characterize these coals in terms of their intrinsic properties, namely: ultimate, proximate, petrographic analysis and Glasser spontaneous tests. The ultimate and proximate analysis showed that spontaneous coal has high contents of carbon, oxygen, and volatile matter as compared to non-spontaneous coal, making it more susceptible to spontaneous combustion. Non-spontaneous coal has higher ash content than the spontaneous coal. Furthermore, the petrographic analysis showed that spontaneous coal has high total reactivity compared to the non-spontaneous coal. Results from Glasser spontaneous test indicate that spontaneous coal absorbs more oxygen than non-spontaneous coal, which explains why spontaneous coal is more susceptible to spontaneous combustion. High reactive coal has low values of critical self-heating temperature (CSHT), indicating that this coal has potential of spontaneous ignition.

  16. The South African energy scene

    International Nuclear Information System (INIS)

    Burger, H.T.

    1983-01-01

    The basic objective of any energy policy is to ensure that the energy-economy of the country developes in accordance with the national interest and promotes national well-being. Energy policies are necessarily based on the tenet of adequate energy availability at acceptable cost levels. Energy policy will evolve in each country to suit the particular circumstances applicable to that country. The overriding aspect of the South African energy policy is the striving towards maximum energy self-sufficiency under secure conditions. This implies maximum reduction and replacement of imported crude oil within financial and manpower constraints. In South Africa energy is not only one of the most important production factors in national economy, but also an important catalyst and stimulus for economic growth and development. The controlled export of energy can be utilized to enhance foreign exchange earnings. The various energy carriers and elements of the South African energy economy can consequently be discussed and evaluated as they are affected by the energy policy guidelines and objectives

  5. Distributed leadership in South African schools: possibilities and constraints

    Directory of Open Access Journals (Sweden)

    Clarence G Williams

    2011-01-01

    Full Text Available Before 1994 South African teachers in general, but more specifically women teachers, were effectively excluded from fulfilling meaningful roles as leaders at school level. Since 1994 the Department of Education has promulgated a number of policies in an attempt to actualize distributed leadership in South African schools. Fundamental to distributed leadership is the belief that all teachers have the right and potential to participate in decisions that affect their work. This article unpacks the theoretical underpinnings of the notion of distributed leadership and then investigates the numerous and diverse factors which have prevented the actualization of distributed leadership in South African schools. It is suggested that distributed leadership within schools can be actualized if the combined knowledge, expertise and experience of various role-players and stakeholders are harnessed in a collaborative fashion. While a healthy bout of idealism is required it is important that this idealism be moderated by the recognition of the realities of the South African situation.

  13. "Women...mourn and men carry on": African women storying mourning practices: a South African example.

    Science.gov (United States)

    Kotzé, Elmarie; Els, Lishje; Rajuili-Masilo, Ntsiki

    2012-09-01

    African mourning of loss of lives in South Africa has been shaped by discursive practices of both traditional African cultures and the sociopolitical developments under apartheid and in post-apartheid South Africa. This article reports on changes in mourning practices on the basis of a literature review and uses a collection of examples to highlight the navigation of some cultural and gendered issues relating to mourning, against the backdrop of the everyday experiences of loss of life in South Africa due to violence and HIV/AIDS. The article draws on African womanist and feminist scholarship and focuses on the intersections between cultural and gender practices of bereavement in the lives of professional urban African women. The authors argue for the use of positioning theory and witnessing practices to honor and story the ongoing struggle of African women as these women take different agentic positions by accepting, questioning, resisting, and/or changing cultural mourning practices while they compassionately witness the self and others in the narratives they live.

  19. Coal in sub-Saharan-African countries undergoing desertification

    Science.gov (United States)

    Weaver, J.N.; Brownfield, M.E.; Bergin, M.J.

    1990-01-01

    Coal has been reported in 11 of the 16 sub-Saharan countries discussed in this appraisal: Mauritania, Senegal, Mali, Niger, Benin, Nigeria, Cameroon, Central African Republic, Sudan, Ethiopia, and Somalia. No coal occurrences have been reported in Gambia, Togo, Burkina, Chad, and Djibouti but coal may be present within these countries because neighboring countries do contain coal-bearing rocks. Most of these countries are undergoing desertification or will in the near future. Wood, directly or in the form of charcoal, constitutes two-thirds of the fuel used in Africa. Destruction of forest and shrub lands for fuel is occurring at an increasing rate because of desertification and increasing energy demands. The decline in biological productivity, coupled with concentration of population in areas where water is available and crops may be grown, leads to increasing shortages of wood for fuel. Part of the present and future energy needs of the sub-Saharan region could be met by use of indigenous coal and peat. Nine sedimentary basins, completely or partially within the sub-Saharan region, have the potential of either coal and/or peat deposits of economic value: 1- Senegal Basin, 2- Taoudeni Basin and Gao Trough, 3- Niger Basin, 4- Chad Basin, 5- Chari Basin, 6- Benue Trough (Depression), 7- Sudan Trough, 8- Plateau and Rift Belt, and 9- Somali Basin. Niger and Nigeria are the only countries in sub-Saharan Africa in which coal is presently being mined as a fuel source for powerplants and domestic use. Peat occurs in the deltas, lower river, and interdunal basin areas of Senegal, Mauritania, and Sudan. Peat can be used as an alternate fuel source and is currently being tested as a soil amendment in the agricultural sector. Coal and peat exploration and development studies are urgently required and should be initiated so the coal and peat utilization potential of each country can be determined. The overall objective of these studies is to establish, within the sub

  15. Exposure to lead in South African shooting ranges

    International Nuclear Information System (INIS)

    Mathee, Angela; Jager, Pieter de; Naidoo, Shan; Naicker, Nisha

    2017-01-01

    Introduction: Lead exposure in shooting ranges has been under scrutiny for decades, but no information in this regard is available in respect of African settings, and in South Africa specifically. The aim of this study was to determine the blood lead levels in the users of randomly selected private shooting ranges in South Africa's Gauteng province. Methods: An analytical cross sectional study was conducted, with participants recruited from four randomly selected shooting ranges and three archery ranges as a comparator group. Results: A total of 118 (87 shooters and 31 archers) were included in the analysis. Shooters had significantly higher blood lead levels (BLL) compared to archers with 36/85 (42.4%) of shooters versus 2/34 (5.9%) of archers found to have a BLL ≥10 μg/dl (p<0.001). Conclusion: Shooting ranges may constitute an import site of elevated exposure to lead. Improved ventilation, low levels of awareness of lead hazards, poor housekeeping, and inadequate personal hygiene facilities and practices at South African shooting ranges need urgent attention. - Highlights: • This is the first study, to our knowledge, of lead exposure in shooting ranges in an African setting. • This study indicates highly elevated lead exposure amongst the users of certain private shooting ranges in South Africa. • Lead exposure may be a serious, yet under-studied, source of adult lead exposure in South Africa, and possibly elsewhere on the African continent.

  1. Mercury emissions from South Africa’s coal-fired power stations

    Full Text Available Mercury is a persistent and toxic substance that can be bio-accumulated in the food chain. Natural and anthropogenic sources contribute to the mercury emitted in the atmosphere. Eskom’s coal-fired power stations in South Africa contributed just under 93% of the total electricity produced in 2015 (Eskom 2016. Trace amounts of mercury can be found in coal, mostly combined with sulphur, and can be released into the atmosphere upon combustion. Coal-fired electricity generation plants are the highest contributors to mercury emissions in South Africa. A major factor affecting the amount of mercury emitted into the atmosphere is the type and efficiency of emission abatement equipment at a power station. Eskom employs particulate emission control technology at all its coal-fired power stations, and new power stations will also have sulphur dioxide abatement technology. A co-beneficial reduction of mercury emissions exists as a result of emission control technology. The amount of mercury emitted from each of Eskom’s coal-fired power stations is calculated, based on the amount of coal burnt and the mercury content in the coal. Emission Reduction Factors (ERF’s from two sources are taken into consideration to reflect the co-benefit received from the emission control technologies at the stations. Between 17 and 23 tons of mercury is calculated to have been emitted from Eskom’s coal-fired power stations in 2015. On completion of Eskom’s emission reduction plan, which includes fabric filter plant retrofits at two and a half stations and a flue gas desulphurisation retrofit at one power station, total mercury emissions from the fleet will potentially be reduced by 6-13% by 2026 relative to the baseline. Mercury emission reduction is perhaps currently not the most pressing air quality problem in South Africa. While the focus should then be on reducing emissions of other pollutants which have a greater impact on human health, mercury emission reduction

    2006-06-01

    Full Text Available A description is provided of work performed as part of the fruit logistics infrastructure project commissioned by the South African Deciduous Fruit Producers’ Trust and coordinated by the South African Council for Scientific and Industrial Research, as described in [Van Dyk FE & Maspero E, 2004, An analysis of the South African fruit logistics infrastructure, ORiON, 20(1, pp. 55–72]. After a brief introduction to the problem, two models (a single-commodity graph theoretic model and a multi-commodity mathematical programming model are derived for determining the maximal weekly flow or throughput of fresh fruit through the South African national export infrastructure. These models are solved for two extreme seasonal export scenarios and the solutions show that no export infrastructure expansion is required in the near future - observed bottlenecks are not fundamental to the infrastructure and its capacities, but are rather due to sub-optimal management and utilisation of the existing infrastructure.

  8. Analysis of radioactivity in coal, cinders, fly ash and discharges from the stack

    International Nuclear Information System (INIS)

    Meide, A.

    1985-01-01

    Gamma measurements of coal samples originating from several supplying countries proved that the South African coal has about double U-238 and Ra-226 concentration and about treble Th-232 concentration compared to coal from the other countries. Gamma measurements of coal, cinders and fly ash samples from five coal-fueled plants indicate somewhat higher concentrations of Th-232 in cinders and U-238 and Th-232 in fly ashes than those described in literature. The ratio Po-210/Pb-210 was about 2 for fly ash particulates <35μ. A positive correlation between ash percentage and radioactivity of coal might be assumed. (EG)

  9. GIS Representation of Coal-Bearing Areas in Africa

    Merrill, Matthew D.; Tewalt, Susan J.

    2008-01-01

    The African continent contains approximately 5 percent of the world's proven recoverable reserves of coal (World Energy Council, 2007). Energy consumption in Africa is projected to grow at an annual rate of 2.3 percent from 2004 through 2030, while average consumption in first-world nations is expected to rise at 1.4 percent annually (Energy Information Administration, 2007). Coal reserves will undoubtedly continue to be part of Africa's energy portfolio as it grows in the future. A review of academic and industrial literature indicates that 27 nations in Africa contain coal-bearing rock. South Africa accounts for 96 percent of Africa's total proven recoverable coal reserves, ranking it sixth in the world. This report is a digital compilation of information on Africa's coal-bearing geology found in the literature and is intended to be used in small scale spatial investigations in a Geographic Information System (GIS) and as a visual aid for the discussion of Africa's coal resources. Many maps of African coal resources often include points for mine locations or regional scale polygons with generalized borders depicting basin edges. Point locations are detailed but provide no information regarding extent, and generalized polygons do not have sufficient detail. In this dataset, the polygons are representative of the actual coal-bearing lithology both in location and regional extent. Existing U.S. Geological Survey (USGS) digital geology datasets provide the majority of the base geologic polygons. Polygons for the coal-bearing localities were clipped from the base geology that represented the age and extent of the coal deposit as indicated in the literature. Where the 1:5,000,000-scale geology base layer's ages conflicted with those in the publications, polygons were generated directly from the regional African coal maps (1:500,000 scale, approximately) in the published material. In these cases, coal-bearing polygons were clipped to the literature's indicated coal

  12. Depression in the South African workplace

    2016-05-01

    Full Text Available Depression is a common psychiatric disorder and can be costly, having a significant impact on the individual and employers. The South African Depression and Anxiety Group (SADAG in partnership with HEXOR, with the support of Lundbeck, undertook research into depression in the workplace, because South African information is not available on this topic. It provides insight into the prevalence of depression within the workplace in South Africa, as well as the impact of depression on the employees and employers in terms of sick leave and levels of productivity, especially when the symptoms include cognitive impairment. It is apparent that stigma plays a pivotal role in the reasons for non-disclosure to employers. It further highlights the magnitude of awareness, early detection and the provision of a holistic support system within the work environment, free from bias, to ensure that optimum benefit can be achieved for both employer and employee.

  13. An overview of South African psychology.

    Cooper, Saths; Nicholas, Lionel

    2012-01-01

    This overview of psychology in South Africa presents a concise and historical account of its science and practice, from its early origins in the late nineteenth century to the present, and traces seminal influences on the discipline. It is a review of how psychology in South Africa developed over more than a century to become one of the most popular subjects in universities and an established and recognized profession, whose members play a variety of roles in the South African polity and larger society. The impact that apartheid racism had on key aspects of psychology's development is traversed, and the influences that previous ruling party politics had on professional psychological organizations are delineated. The unification of psychology under the Psychological Society of South Africa, a few months before the advent of democracy in South Africa, is explicated. The protection of the title of psychologist in law and certain other changes in the legislative environment, enabling a greater role for psychologists, are reported. The primary research sites for psychology and its funding and the main university psychology programs are described, as are the requirements for registration and licensure. The genesis and the importance of the work of internationally acclaimed South African psychologists, such as J. Wolpe and A. A. Lazarus, are contextualized. With the increased participation of progressive black psychologists in leadership and research in the past two decades, a transformed psychology has the potential to play a significant role in addressing human issues confronting South Africa.

  15. Cash flow forecast for South African firms

    Directory of Open Access Journals (Sweden)

    Yun Li

    2015-06-01

    Full Text Available This paper applies models in the extant literature that have been used to forecast operating cash flows to predict the cash flows of South African firms listed on the Johannesburg Stock Exchange. Out-of-sample performance is examined for each model and compared between them. The reported results show that some accrual terms, i.e. depreciation and changes in inventory do not enhance cash flow prediction for the average South African firm in contrast to the reported results of studies in USA and Australia. Inclusion of more explanatory variables does not necessarily improve the models, according to the out-of-sample results. The paper proposes the application of moving average model in panel data, and vector regressive model for multi-period-ahead prediction of cash flows for South Africa firms.

  15. Supplement to South African national bibliography on radioanalytical chemistry: South African authors only. 1975-1982

    International Nuclear Information System (INIS)

    1984-07-01

    The South African National Bibliography on Radioanalytical Chemistry was initiated by Dr Max Peisach of the National Accelerator Centre, Faure (formerly SUNI) and is intended to cover books, papers and reports published by South African scientists while affiliated to South African institutes, even if the work was carried out at foreign laboratories. The first edition (SUNI 56) covered material published to the end of 1977. The present edition is a supplement to the former and covers the period 1975 to 1982. The papers are divided into two categories. The first consists of papers on activation analysis, whether delayed or prompt and deals with the following: charged particle activation analysis, neutron activation analysis, photon activation and x-ray (including particle-induced x-ray emission, PIXE), prompt analysis and scattering, but is restricted to nuclear particle scattering. The second category deals with radioanalytical methods. To restrict the subject matter to those papers which stress the analytical approach and use nuclear techniques, this category has been sub-divided into the following subjects: absolute standardisation; computer techniques directly concerned with analysis; counting techniques for measuring radionuclides, nuclear particles or emissions; environmental monitoring related to the measurement of radioactive substances; instrumentation and techniques related to nuclear analytical methodology; isotope dilution analysis; low activity measurements; natural radioactivity counting; radiography; radiotracer methods excluding the routine diagnostic use of radionuclides in medicine and separation techniques. Titles are arranged in order of the year of publication, and with each year in alphabetical order of the surname of the first (and thereafter the next) author

    Cermak, T.; Roubicek, V.

    1993-01-01

    The Czech coal and power engineering base is in a deep restructuring period now. The basic problems represents the changeover from the system of the centrally planned state economy to the market model of the energy resources mining, production and consumption. The Czech economy will have to face to up to now unknown competitive forces on the coal market in Europe where American, Canadian, Australian and South African coals compete. The paper discusses historical aspects of the development of the coal mining industry in the Czechoslavakia, the present coal preparation techniques for coking coals, the coking industry, and the utilization of brown coal. How to utilize the domestic coal base and coal generally is closely connected with the global restructuralization of the Czech economy. The most difficult step of this process is undoubtedly the adaptation of the Czech fuel and energy base to the market economy conditions

Abandoned coal mine groundwater is also usually high in copper, zinc, mercury, and lead. Groundwater from abandoned mines can seriously affect public health through the discharge of non-point source pollution. This paper presents information on a research project regarding the possible impacts of abandoned coal mines and its effects on groundwater as it relates to the health of residents in South Wellington, Nanaimo, British Columbia. The purpose of the project is to determine which illnesses are more common in South Wellington, Nanaimo and in the control area. The paper provides a discussion of the Nanaimo coal field and three major seams; the Wellington, Newcastle and Douglas which are most likely to have a significant impact on groundwater in South Wellington. 27 refs.

    The South African Country Study Programme is being executed under the auspices of the South African Department of Environmental Affairs and Tourism (DEAandT). The full study comprises the following four components, each headed by a technical coordinator: the 1990 greenhouse gas emissions inventory; a study of South Africa`s vulnerability to climate change and possible adaptation strategies; potential mitigation actions and; policy development. Ideally, these components should be executed in sequence. However, in view of South Africa`s commitments in terms of the Framework Convention on Climate Change (FCCC) and the need to draw up a national communication, it was decided to execute the components simultaneously, with an emphasis on coordination between the components.

    With South African coal exports projected to increase by more than 35% over the next decade, will the development of the country's infrastructure be ready? A combination of derailments, bad weather and a lack of capacity on the Transnet Freight Rail (TFR) rail network seriously curtailed shipments in 2008 and 2009. It had been hoped that Richards Bay Coal Terminal(RPCT) would now be able to make use of its expanded capacity but a serious transport strike may encourage traders to switch to Mozambican ports.

  10. Intrinsic rewards and work engagement in the South African retail industry

    Directory of Open Access Journals (Sweden)

    Sara Jacobs

    2014-11-01

    Research purpose: The purpose of this research was to determine whether there is a relationship between intrinsic rewards and work engagement in the South African retail industry. Furthermore, it sought to validate an instrument to measure intrinsic rewards within the South African context. Motivation for the study: There is currently a paucity of research exploring intrinsic rewards, specifically their importance for work engagement. Furthermore, there is a lack of instruments validated in South Africa that can be used to measure intrinsic rewards. Research approach, design and method: This quantitative study was conducted using a cross-sectional design and non-probability sampling of 181 employees from a South African retail organisation. The questionnaire included a demographic section, the Utrecht Work Engagement Scale and the Work Engagement Profile. Main findings: Statistically significant, positive relationships were found between all subscales of the two instruments. There were significant differences in the means for intrinsic rewards and work engagement for gender and age. Notably, the exploratory factor analysis for both instruments did not support the factor structure indicated in the literature. Practical/managerial implications: South African retail organisations should create work environments that provide intrinsic rewards as part of their reward package, to encourage work engagement. Contribution/value-add: These findings add to the current body of literature regarding intrinsic rewards and work engagement and provide insight into variables that promote work engagement within the South African retail context.

  12. Price negotiation of coal to be loaded in 1989

    Energy Technology Data Exchange (ETDEWEB)

    Senmura, Akira (Institute of Energy Economics, Tokyo (Japan))

    1989-06-01

    The Institute of Energy Economics summarized the negotiated prices for coals to be loaded in 1989 for coke making coal and non coking coal. In order to suppress the price increase of coke making coal as low as possible, five iron making companies where Nippon Steel and Kawasaki Steel are the center, started to negotiate from US showing lower markup requirement and decided to increase the price from $1.65 to $2. They agreed to increase the price for Australian coal as follows: $3.5 for coke making coal, $5.5 for slightly coking coal, $4.5 for weakly coking coal and further they contracted with $3.5 markup and $3.5 markup for China and USSR coals from December, 1988 to March, 1989. The negotiation for non coking coal started from USSR similarly and agreed with $3 markup for USSR coal, $5.3 markup for South African coal, and $3.5 markup for Australian coal but the negotiation is performing to China coal on Australian basis. The Australian share for non coking coal is higher, that is, 70% and therefore Japanese power generating companies are promoting to import non coking coal from US for the competition. 5 tabs.

  13. South African teachers’ exposure to workplace bullying

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Research on workplace bullying (WPB in occupations, identified teaching as a high risk job. Yet there is a dearth of research on WPB among teachers. The aim of this study is to contribute to the limited body of knowledge on the prevalence of WPB within an international and South African schooling context. This article reports on results from an exploratory study on South African teachers’ exposure to WPB. Self-reporting questionnaires were completed by a convenient, voluntary sample of teachers (n=999. The respondents had to indicate their exposure to 43 pre-defined acts of WPB clustered into four categories. This study exposes the commonness of WPB among participating teachers: 90.8% of them were victims of WPB during the 12 months that preceded the study, and 89.1% of the victims had been exposed to at least two different categories of WPB. The perpetrators tried especially to undermine the victims’ professional status and isolate them. The study identified the constant evaluation of victims’ performance as the most common of the 43 negative acts. The results are discussed with reference to other studies. It is concluded that WPB is a serious problem in South African schools and needs to be addressed on policy and institutional levels.

  8. The importance of biographic research: a South African black nurses' perspective.

    Science.gov (United States)

    Mhlongo, T P

    1999-09-01

    This article is an attempt to highlight the importance of biographic research to South African nursing. The writer believes that a particular attention should be paid to the contributions of South African Black/African nurse practitioners. South Africa has produced remarkable African nurses: they range from nurse Professors and Head of the University Nursing Departments to clinical nursing specialists and nursing administrators. The writer--having used the biographical approach in his Doctoral thesis--will highlight some practical and professional issues around biographic research. For the purpose of this publication, however, discussion will be confined to defining biographic research, reviewing different types of biographies, and discussing the value of the biographical research. Furthermore, the writer will identify some biographic concepts, examine their relationships, draw inferences and (hopefully) emerge with an increased understanding of the impact of biography as scientific concept.

  15. International positioning of South African electricity prices and commodity differentiated pricing

    Directory of Open Access Journals (Sweden)

    George A. Thopila

    2013-07-01

    Full Text Available The South African electricity industry has seen a dramatic increase in prices over the past 3 years. This increase has been blanketed across all sectors and is based on a number of factors such as sector, usage and, in the case of domestic pricing, suburb. The cost of electricity in South Africa, particularly to the industrial sector, has been among the lowest in the world. In this paper, we analyse the recent price increases in the South African electricity sector and discuss the price determination mechanism employed by Eskom, South Africa's electricity provider. We also analyse the revenue and sales of Eskom and review the electricity price from an international perspective. The concept of differential pricing and international benchmarking is analysed as a possibility for the South African industrial electricity industry, so that all sectors are not adversely affected by across-the-board increases. Our aim is to raise the question of whether South Africa's electricity prices are in line with international increases and to suggest the possibility of differentiated prices in the local electricity sector.

  4. Paraphilia and sex offending - A South African criminal law perspective.

    Science.gov (United States)

    Carstens, Pieter; Stevens, Philip

    2016-01-01

    Historically, the link between sexual deviance and criminality has been described and documented, asserted by psychiatry, and manifested in law. Laws that have regulated sexual behaviour have referred to terms such as 'sexual deviation', 'sexual perversion' or even archaic moral terms such as 'unnatural acts and unspeakable crimes against nature'. A possible link between sexual perversion, psychopathy, and criminality, specifically manifesting in sexual homicide, has been the subject of remarkable research in forensic psychiatry. This contribution examines the phenomenon of paraphilia with specific reference to its definition, diagnostic classification and characteristics, as well as a few selections of incidences of paraphilia in South African criminal case law. A brief assessment is made of how South African criminal courts have dealt with paraphilia. In this regard, an analysis is made of the criminal liability of the paraphiliac. The South African response to sexual deviation as addressed in the Criminal Law (Sexual Offences and Related Matters) Amendment Act 32 of 2007 will also be addressed with reference to its efficacy in addressing paraphilia within South African criminal law. The interface between criminal law and medical ethics within the context of this theme will also be canvassed. In conclusion, recommendations for possible reform are canvassed. Copyright © 2016.

  7. Genetic analysis of three South African horse breeds

    Directory of Open Access Journals (Sweden)

    E.G. Cothran

    1998-07-01

    Full Text Available Genetic variability at 7 blood-group and 10 biochemical genetic loci was examined in 3 South African horse breeds, the Nooitgedacht, Boerperd and Basuto Pony. Observed heterozygosity for these breeds was intermediate for domestic horses, with the highest heterozygosity in the Boerperd and the lowest in the Basuto Pony. The 3 breeds show greater genetic similarity to each other than to other domestic horse breeds. Compared to other breeds, the South African breeds show greater genetic similarity to breeds such as the Thoroughbred, Holstein, Trakehner and Hanovarian and also to North American breeds such as the Saddlebred, Standardbred and Morgan Horse.

  8. Urban Ecology in Cape Town: South African Comparisons and Reflections

    Directory of Open Access Journals (Sweden)

    Sarel S. Cilliers

    2012-09-01

    Full Text Available Little urban ecological research has been done in South Africa. The papers in the Ecology and Society special feature Urban Ecological and Social-Ecological Research in the City of Cape Town make, therefore, an important contribution to the development of urban ecology locally and globally. Different approaches have been used in the study of urban ecology of different urban areas in South Africa. Cape Town is situated in a biodiversity hotspot and is the only South African city which includes a national park. As a result the urban ecological studies were mainly driven by urban nature conservation concerns. In other cities such as Durban, open space planning and environmental management were the major issues which focused ecological studies on urban areas whereas other studies of urban areas in the Eastern Cape and North-West provinces included private and public open spaces and man-made habitats. We reflect on the Cape Town studies in a South African context and highlight conservation of biodiversity, protection of ecosystem services, management of control measures, and the conflict between humans and nature. A brief synthesis has also been given of South African urban ecological research in general.

  15. Colonialism, Biko and AIDS: reflections on the principle of beneficence in South African medical ethics.

    Science.gov (United States)

    Braude, Hillel David

    2009-06-01

    This paper examines the principle of beneficence in the light of moral and epistemological concerns that have crystallized in the South African context around clinical care. Three examples from the South African experience affecting the development of bioethics are examined: medical colonialism, the death in detention of Steve Biko, and the HIV/AIDS epidemic. Michael Gelfand's book [(1948). The sick African: a clinical study. Cape Town: Stewart Printing Company.] on African medical conditions captures the ambiguous nature of colonial medicine that linked genuine medical treatment with the civilizing mission. Biko's death was a key historical event that deeply implicated the medical profession under apartheid. The present HIV/AIDS epidemic presents the gravest social and political crisis for South African society. All three experiences influence the meaning and relevance of beneficence as a bioethics principle in the South African context. This paper argues for a South African bioethics informed by a critical humanism that takes account of the colonial past, and that does not model itself on an "original wound" or negation, but on positive care-giving practices.

  2. Astronomy for teachers: A South African Perspective

    Science.gov (United States)

    de Witt, Aletha; West, Marion; Leeuw, Lerothodi; Gouws, Eldrie

    2015-08-01

    South Africa has nominated Astronomy as a “flagship science” and aims to be an international Astronomy hub through projects such as the Square Kilometre Array (SKA) and the South African Large Telescope (SALT). These projects open up career opportunities in maths, science and engineering and therefore offers a very real door for learners to enter into careers in science and technology through Astronomy. However, the Trends in International Mathematics and Science Survey (TIMSS), the Global Competitiveness Report (GCR) and Annual National Assessment (ANA) have highlighted that South Africa’s Science and Mathematics education is in a critical condition and that South African learners score amongst the worst in the world in both these subjects. In South Africa Astronomy is generally regarded as the worst taught and most avoided Natural Science knowledge strand, and most teachers that specialised in Natural Sciences, never covered Astronomy in their training.In order to address these issues a collaborative project between the University of South Africa (UNISA) and the Hartebeesthoek Radio Astronomy Observatory (HartRAO) was initiated, which aims to assist teachers to gain more knowledge and skills so that they can teach Astronomy with confidence. By collaborating we aim to ensure that the level of astronomy development will be raised in both South Africa and the rest of Africa.With the focus on Teaching and Learning, the research was conducted within a quantitative paradigm and 600 structured questionnaires were administered to Natural Science teachers in Public primary schools in Gauteng, South Africa. This paper reports the findings of this research and makes recommendations on how to assist teachers to teach Astronomy with confidence.

  3. The Universal Jurisdiction of South African Criminal Courts and Immunities of Foreign State Officials

    Directory of Open Access Journals (Sweden)

    Evode

    2015-12-01

    Full Text Available Under the "complementarity" regime of the Rome Statute of the International Criminal Court (ICC, the jurisdiction of the ICC is secondary to the jurisdiction of domestic courts. States Parties, not the ICC, have the primary responsibility of investigating and prosecuting international crimes. The ICC acts only when States are "unable" or "unwilling" to prosecute. As a State Party, in order to give effect to the complementarity principle, South Africa enacted the Implementation of the Rome Statute of the International Criminal Court Act 27 of 2002, which determines the modalities of prosecuting perpetrators of the crimes of genocide, crimes against humanity and war crimes in South African courts. The Implementation Act also provides that South African courts will have jurisdiction over these crimes not only when they are committed on the territory of South Africa but also when they are committed outside the Republic. By granting South African courts jurisdiction over a person who commits a crime outside the Republic when that person is later found on South African territory, without regard to that person's nationality or the nationality of the victims, the Implementation Act empowers South African courts with universal jurisdiction over international crimes. This paper seeks to determine whether and to what extent foreign State officials, such as foreign heads of State, heads of government and ministers of foreign affairs, can plead immunity when they are accused of international crimes before South African courts when exercising their universal jurisdiction in terms of the Implementation Act and in accordance with the complementarity regime of the Rome Statute. In other words, the article endeavours to determine whether international law rules regarding immunities of State officials may or may not limit the ability of South African courts to exercise universal jurisdiction over international crimes committed in foreign States.

  5. The South African Forum for Radiation Protection

    International Nuclear Information System (INIS)

    Basson, J.K.; Le Roux, P.R.

    1993-01-01

    The use of ionising radiation in South Africa since the turn of the century was initially limited to x-rays and radium, with predominant applications in medicine for diagnosis and therapy. Since 1948 artificial radio-isotopes have been increasingly available and such applications have been widely extended to industry, agriculture and science. Initially, the Council for Scientific and Industrial Research developed radiation protection in South Africa. It was later recommended that an independent forum, the South African Forum for Radiation Protection, be established. The activities of the Forum are described

  6. Radiation and convective heat transfer, and burnout in oxy-coal combustion

    Energy Technology Data Exchange (ETDEWEB)

    J.P. Smart; P. O' Nions; G.S. Riley [RWE npower, Swindon (United Kingdom)

    2010-09-15

    Measurements of radiative and convective heat transfer, and carbon-in-ash have been taken on the RWEn 0.5 MWth combustion test facility (CTF) firing two different coals under oxy-fuel firing conditions. The two coals fired were a Russian Coal and a South African Coal. Recycle ratios were varied within the range of 65-75% dependent on coal. Furnace exit O{sub 2} values were maintained at 3% and 6% for the majority of tests. Air firing tests were also performed to generate baseline data. The work gives a comprehensive insight into the effect of oxy-fuel combustion on both radiative and convective heat transfer, and carbon-in-ash compared to air under dry simulated recycle conditions. Results have shown peak radiative heat flux values are inversely related to the recycle ratio for the two coals studied. Conversely, the convective heat flux values increase with increasing recycle ratio. It was also observed that the axial position of the peak in radiative heat flux moves downstream away from the burner as recycle ratio is increased. A 'working range' of recycle ratios exists where both the radiative and convective heat fluxes are comparable with air. Carbon-in-ash (CIA) was measured for selected conditions. For air firing of Russian Coal, the CIA for follows and expected trend with CIA decreasing with increasing furnace exit O{sub 2}. The CIA data for the two recycle ratios of 72% and 68% for the same coal show that the CIA values are lower than for air firing for corresponding furnace exit O{sub 2} levels and vary little with the value of furnace exit O{sub 2}. CIA measurements were taken for the South African Coal for a range of recycle ratios at 3% and 6% furnace exit O{sub 2} levels. Results indicate that the CIA values are lower for higher furnace exit O{sub 2}. 32 refs., 11 figs., 1 tab.

  14. A (South African voice on youth ministry research: Powerful or powerless?

    Directory of Open Access Journals (Sweden)

    Shantelle Weber

    2015-11-01

    Full Text Available Research on youth ministry in Africa and specifically South Africa traces its origin to much research conducted in America and Europe. Many African scholars also draw on research and practices within these international spheres. Empirical research on youth ministry in Africa is however of great importance. For this purpose, comparative analysis research provides a research methodology in the social sciences that aims to make comparisons across different countries or cultures. A major problem in comparative research is that the data sets in different countries may not use the same categories, or define categories differently. This article makes use of a faith formation case study conducted in South Africa to highlight the value of this methodology when reflecting on international research from an African perspective. The main argument of this article is that international research on youth ministry is valuable in an African context but this research needs to be culturally contextualised through using comparative analysis as a research tool. This will reflect that there are many similarities between international youth ministry and the African context but there are also many cross-cultural disparities. After comparison, differences that are unique to the African context are noted. The article focuses on South Africa as a reflection of youth ministry within the broader African context.

  18. Occupational exposure in South African metallurgical plants and industries involving naturally occurring radionuclides

    International Nuclear Information System (INIS)

    Kruger, I.D.

    2002-01-01

    South Africa has a very large mining and minerals processing industry exploiting a variety of ores and minerals containing elevated levels of NORM. The industry employs more than 300,000 persons. Doses have been assessed to workers in the mining industry in South Africa. In the gold mining industry radon measurements have been performed since the early 1970s. Regulations have been in force since 1990. The mean annual dose to underground gold mine workers, mostly from radon progeny, is about 5 mSv with maximum doses exceeding 20 mSv. The maximum annual dose to surface workers in gold mines is 5 mSv. In South African coal mines the mean annual dose from inhalation of radon decay products has been estimated from limited radon concentration measurements to be about 0.6 mSv. In the phosphoric acid and fertilizer production industry the doses to the workers do not exceed 6 mSv/y. There are 3 mineral sands operations in South Africa, for which the maximum annual dose to workers is 3 mSv. One open pit copper mine contains elevated levels of U, which is extracted as a by-product. The maximum annual doses to workers are 5 mSv for workers in the mine and 20 mSv for workers in the metallurgical plant. Worker doses in the metallurgical plant have since been reduced with the introduction of radiation protection measures

  20. Hand-arm vibration syndrome in South African gold miners.

    Science.gov (United States)

    Nyantumbu, Busi; Barber, Chris M; Ross, Mary; Curran, Andrew D; Fishwick, David; Dias, Belinda; Kgalamono, Spo; Phillips, James I

    2007-01-01

    Hand-arm vibration syndrome (HAVS) is associated with the use of hand-held vibrating tools. Affected workers may experience symptoms of tingling, numbness, loss of grip strength and pain. Loss of dexterity may impair everyday activities, and potentially increase the risk of occupational accidents. Although high vibration levels (up to 31 m/s(2)) have been measured in association with rock drills, HAVS has not been scientifically evaluated in the South African mining industry. The aim of this study was to determine the prevalence and severity of HAVS in South African gold miners, and to identify the tools responsible. A cross-sectional study was conducted in a single South African gold-mine. Participants were randomly selected from mineworkers returning from annual leave, comprising 156 subjects with occupational exposure to vibration, and 140 workers with no exposure. Miners who consented to participate underwent a clinical HAVS assessment following the UK Health and Safety Laboratory protocol. The prevalence of HAVS in vibration-exposed gold miners was 15%, with a mean latent period of 5.6 years. Among the non-exposed comparison group, 5% had signs and symptoms indistinguishable from HAVS. This difference was statistically significant (P < 0.05). All the cases of HAVS gave a history of exposure to rock drills. The study has diagnosed the first cases of HAVS in the South African mining industry. The prevalence of HAVS was lower than expected, and possible explanations for this may include a survivor population, and lack of vascular symptom reporting due to warm-ambient temperatures.

    Full Text Available Globalisation has opened economies more, exposing them to more international shocks and increasing the challenges to which domestic economic policies must respond. This paper provides a starting point for the analysis of the impact of international economic developments on the South African economy by means of graphical illustrations, correlations coefficients and in some cases a VAR analysis. Although this paper has shed some light on the importance of international economic developments on the South African economy, more rigorous econometric investigation is needed to validate the arguments and to address many of the unresolved questions.

  14. The come back of liquid coal

    International Nuclear Information System (INIS)

    Caulier, S.

    2010-01-01

    The coal-to-liquid (CTL) process has made important progresses and is now perfectly mastered by the South-African company Sasol. At least 6 CTL facilities are under construction in China. Each will produce 80000 barrels/day of diesel fuel and the production is planned to start up by 2017 or 2018. The CTL process is profitable when the oil barrel price exceeds 100 US$ but it depends also of the coal price. However, the process itself is highly energy consuming and also highly polluting with strong CO 2 emissions. A solution to these drawbacks would come from the implementation of poly-generation (separate generation of energy, electricity and heat), and from the use of a combined cycle with integrated gasification.

  20. The South African nuclear programme in a strategic perspective

    International Nuclear Information System (INIS)

    Zelinka, Martin; Sůsa, Tomáš

    2017-01-01

    The main idea behind the article is that the strategic aspects of the South African nuclear proliferation programme might be seen from a different point of view. The goal is to gain a perspective by looking into South African history, politics and international status, using these factors as the context for the nuclear programme. First, the authors define the necessary theoretical background, emphasizing the various motivations behind nuclear proliferation. The main focus of the article is on South Africa's motivation – where it came from and which factors influenced it. Among the examined aspects are: historical development and emergence of the regime, internal and external opposition (enemies), international status and the nature of the local political system. The various options South Africa had for actual usage of its nuclear weapons are also considered, The questions as to the motivation, results of nuclear proliferation (whether or not it was successful) and practical use of weapons developed are answered in the conclusion.

  1. South African uranium resource and production capability estimates

    International Nuclear Information System (INIS)

    Camisani-Calzolari, F.A.G.M.; Toens, P.D.

    1980-09-01

    South Africa, along with Canada and the United States, submitted forecasts of uranium capacities and capabilites to the year 2025 for the 1979 'Red Book' edition. This report deals with the methodologies used in arriving at the South African forecasts. As the future production trends of the South African uranium producers cannot be confidently defined, chiefly because uranium is extracted as a by-product of the gold mining industry and is thus highly sensitive to market fluctuations for both uranium and gold, the Evaluation Group of the Atomic Energy Board has carried out numerous forecast exercises using current and historical norms and assuming various degrees of 'adverse', 'normal' and 'most favourable' conditions. The two exercises, which were submitted for the 'Red Book', are shown in the Appendices. This paper has been prepared for presentation to the Working Group on Methodologies for Forecasting Uranium Availability of the NEA/IAEA Steering Group on Uranium Resources [af

  12. The efficiency and quality dilemma: What drives South African call centre management performance indicators?

    Directory of Open Access Journals (Sweden)

    Diane Banks

    2011-03-01

    Research purpose: This study explored the key performance indicators that drive management practices in the South African call centre industry in the context of the dilemma between efficiency and quality. Motivation for the study: The South African government has identified call centres as a method of creating jobs and foreign investment. Management practices affect centres’ performance. Understanding these practices will help to achieve these aims. Research design: The researchers used a web-based questionnaire in a survey with South African call centre managers in more than 44 different organisations that represented nine industry sectors. Main findings: This study indicated that the dilemma between efficiency and quality is prevalent in South African call centres and that efficiency key performance indicators drive management practices. Practical/managerial implications: The inconsistencies the study reported mean that South African organisations should assess the alignment between their organisational visions, the strategic intentions of their call centres and the performance measures they use to assess their call centre managers. Contribution/value-add: This study adds to the relatively small amount of empirical research available on the call centre industry in South Africa. It contributes to the industry’s attempt to position itself favourably for local and international outsourcing opportunities.

    Focusing on the present status and future of coal demand in Central/South American countries and the coal trade between Central/South American countries and the U.S., the paper described the present status and future of coal demand there and the effects on Japan. Export of Colombian coal will amount to approximately 30-35 million tons in 2000. Venezuelan coal 10-20 million tons. The U.S. imported good-quality general coal low in sulfur content, 3.08 tons from Columbia and 1.39 tons from Venezuela. Coal export from the U.S. to Central/South America was mostly of raw material coal, 5 million tons in 1993 and 5.39 million tons in 1994. General coal was 180,000 tons. The U.S. has no plans of increasing US coal export to Central/South America. But it is safely predicted that Columbia and Venezuela will increase coal export to Europe in the future. It will bring about decrease in export of US coal to Europe, which connects with increasing pressure for the coal trade amount of Japan. 21 figs., 47 tabs.

  8. THE INCORPORATION OF DOUBLE TAXATION AGREEMENTS INTO SOUTH AFRICAN DOMESTIC LAW

    Directory of Open Access Journals (Sweden)

    Izelle du Plessis

    2015-11-01

    Full Text Available There are different opinions as to the process whereby double taxation agreements (DTAs are incorporated into South African law. This contribution aims to discuss some of the existing opinions and to offer a further perspective on the matter. At the heart of the debate lies the interpretation of two provisions, namely section 231 of the Constitution of the Republic of South Africa and section 108 of the Income Tax Act and the interaction between the two. This contribution argues that South Africa's DTAs are not self-executing (a term referred to in section 231(4 of the Constitution and should therefore be enacted into law by national legislation. It is furthermore argued that section 108(2 of the Income Tax Act enables a DTA to be incorporated into South African domestic law, by means of publication in the Government Gazette. An analysis of the case law supports this argument. Whether or not DTAs are regarded as self-executing, the status of a DTA in relation to the Income Tax Act still has to be determined. In other words, once the DTA forms part of South African domestic law, does it rank higher, lower or on a par with the Income Tax Act? It is submitted that the status of DTAs in South Africa is determined by the Constitution. It is furthermore submitted that South Africa's DTAs do not attain a status on the same level as the Constitution and that the Constitution allows for the possibility that South Africa's DTAs may be overridden by subsequent legislation (for example, by amendments to the Income Tax Act. Whether or not an override will take place in a specific case should, it is submitted, be determined by the application of the principles of statutory interpretation which apply in the case of conflict. Although this latter submission finds support in the minority judgement in Glenister, both the AM Moolla and Tradehold decisions express contrary views. The hope is expressed that the South African courts will provide clarity on this

  13. DNA-based identification of aquatic invertebrates useful in the South African context?

    Directory of Open Access Journals (Sweden)

    Hermoine J. Venter

    2016-05-01

    Full Text Available The concept of using specific regions of DNA to identify organisms processes such as DNA barcoding is not new to South African biologists. The African Centre for DNA Barcoding reports that 12 548 plant species and 1493 animal species had been barcoded in South Africa by July 2013, while the Barcode of Life Database (BOLD contains 62 926 records for South Africa, 11 392 of which had species names (representing 4541 species. In light of this, it is surprising that aquatic macroinvertebrates of South Africa have not received much attention as potential barcoding projects thus fa barcoding of aquatic species has tended to focus on invasive species and fishes. Perusal of the BOLD records for South Africa indicates a noticeable absence of aquatic macroinvertebrates, including families used for biomonitoring strategies such as the South African Scoring System. Meanwhile, the approach of collecting specimens and isolating their DNA individually in order to identify them (as in the case of DNA barcoding, has been shifting towards making use of the DNA which organisms naturally shed into their environments (eDNA. Coupling environmental and bulk sample DNA with high-throughput sequencing technology has given rise to metabarcoding, which has the potential to characterise the whole community of organisms present in an environment. Harnessing barcoding and metabarcoding approaches with environmental DNA (eDNA potentially offers a non-invasive means of measuring the biodiversity in an environment and has great potential for biomonitoring. Aquatic ecosystems are well suited to these approaches but could they be useful in a South African context?

    1997-06-01

    This project investigates the suitability of a range of native understorey species for rehabilitation at several coal mines in New South Wales. The germination of seeds from 69 species representing 12 families was tested under controlled laboratory conditions. Germination occurred in all but two of the species tested and 50% germination was exceeded by 29 species. Species of the Mimosaceae, Fabaceae and Proteaceae tended to have above average germination; however species representing other families had variable germination results. A pre-germination heat treatment applied to all of the Acacia species increased germination in some but not all species. Seeds of these understorey species which were used in this trial, are native to the New South Wales coal fields and available commercially or are relatively easy to collect. Glasshouse and field trials are now being undertaken to assess establishment and growth on mine soil, spoil and coal reject materials. 9 refs., 5 figs.

  4. Change, organisational culture and the development of the South African Military Academy to 2009

    Directory of Open Access Journals (Sweden)

    G E (Deon Visser

    2011-12-01

    Full Text Available This article investigates the impact of change and organisational culture on the growth and development of the South African Military Academy. It explores the impact of Nationalist Party rule since 1948 and black majority rule since 1994 on the institutional culture of the South African military and how that influenced the development of the Military Academy. This is intertwined with an investigation of the nature and impact of the diverging military and academic subcultures at the Academy. The article contends that, together with the historical exclusion of blacks and women from the military, the marginalisation of white English-speaking citizens by Nationalist Party rule denied the Academy the exploitation of a significant portion of the country’s human resource potential in the interest of institutional development. The same happened with the introduction of racial quotas and the marginalisation of whites since 1994. The Military Academy has, furthermore, historically been too reflective of the organisational culture of the South African National Defence Force and its predecessors instead of informing that culture to meet the challenges of military professionalism. The Academy has a potentially vital educational role to play in the South African and Sub-Saharan African militaries, but requires some changes in its organisational culture to fulfil that mission.

    Full Text Available http://dx.doi.org/10.5007/2175-8026.2011n61p283 Focusing on South African media in Africa as a case study, this article argues that national media regionalisation of those economically dominant countries located geo-politically in the southern hemisphere is paradoxical. On the one hand, it follows the same liberal economic expansionist logic as their Western media counterparts and can pose a serious threat to the development of the national/local media of the recipient countries. On the other, it can foster new forms of cooperation among developing countries in the areas such as programme exchange and local media content production. Despite some advantages, the paper argues, these expansions and particularly the South African ones can function as intermediaries for extension of various forms of Western media and cultural imperialism(s.

    2015-08-01

    Full Text Available This article presents a comparison of central debates in South African labor sociology in the1970s and the contemporary era. I argue that scholars can break through impasses in currentlabor sociology debates by reviving attention to the land-labor-livelihood (LLL connections thatinspired theoretical advancements in the South African literature of the 1970s. After anintroduction and definition of LLL connections, the paper analyzes an exemplary work of thelabor literature of the 1970s, giving special attention to the way in which the LLL focus shapedthe questions asked by the authors. The article proceeds to a review of central debates from thecurrent labor literature, which focuses primarily on issues of the labor movement. It is arguedthat this focus on movements has limited the scope of labor scholarship, resulting in an impassein South African labor debates. An emerging literature that renews attention to the LLLconnections is proposed as a model for moving beyond this impasse. I close the article bydiscussing the implications for this review of South African literature for global laborscholarship.

    Full Text Available The purpose of this study was to validate the Learning Transfer System Inventory (LTSI in the South African context. The sample used in this study was a convenience sample of 240 employees working for a Banking group. Exploratory factor analysis of the LTSI was used to determine if an interpretable factor structure of latent transfer system constructs when applied in the South African context could be identified. From the results it appears that the factor structure of the LTSI, as revealed by means of the exploratory approach, appears differently in the South African context.

    The exploration project in Indonesia covered geological mapping, drilling, geophysical logging, underground water pumping tests, vertical seismic profiling (VSP), and seismic reflection survey. Ten boreholes were drilled. Moreover, coal property analysis, geotechnical rock test, geochemical analysis, and the like were conducted by examining core specimens sampled from the boreholes. It was found that there are three main coal beds which continuously extend to the two ends of the synclinic structure. It was also found that there is a 6m-thick coal bed 200m further below the three main coal beds, and it is estimated to produce approximately 6,000kcal/kg. Coal from two of the three beds produces 5,000kcal/kg, containing but a little ash and sulfur. Coal from the third includes 1.17% of sulfur. Coal in all the beds is summed up, and then it is estimated that there is approximately 1,054-million tons of coal in reserve in the South Arahan area. (NEDO)

    2016-05-01

    Research purpose: The study analysed the relationship between sustainability performance and FP in South African listed companies. Motivation for the study: Some South African listed companies acknowledge in their sustainability reports that there is a link between sustainability development and long-term shareholder value. This implies that FP is linked to sustainable development performance. This relationship has not been researched for South African listed companies and therefore needs to be investigated. Research design, approach and method: A similar research method was used as for an international study. Forty-five listed South African companies were selected as the sample. Their sustainable development reports were used for analysis. Data were analysed with the use of content and a canonical correlation analysis. Main findings: The results of the study revealed that an overall positive relationship exists between sustainability performance and FP. Practical implications: South African companies that have a high involvement and focus on specific sustainable development initiatives that are integrated into overall sustainable development strategy can deliver improved FP for the organisation and deliver long-term value to its shareholders. Contribution: Six sustainable development aspects were found to be significantly correlated with improved FP and if incorporated into a company’s sustainable development strategy can lead to increased successes.

    Conclusion: South African universities are still not places where all students are equally able to integrate socially. DUSMs know what ought to be done to make campuses more accessible and welcoming to students with disabilities and should be empowered to play a leading role in sensitising non-disabled members of universities, to create greater awareness of, and appreciation for, the multiple ways in which wheelchair user students continue to be excluded from full participation in university life. South African universities need to adopt a systemic approach to inclusion, which fosters an understanding of inclusion as a fundamental right rather than as a luxury.

    Little is known regarding the links between mental disorder and lost income in low- and middle-income countries. The purpose of this study was to investigate the association between mental disorder and lost income in the first nationally representative psychiatric epidemiology survey in South Africa. A probability sample of South African adults was administered the World Health Organization Composite International Diagnostic Interview schedule to assess the presence of mental disorders as defined in the Diagnostic and Statistical Manual of Mental Disorders, version IV. The presence of severe depression or anxiety disorders was associated with a significant reduction in earnings in the previous 12 months among both employed and unemployed South African adults (p = 0.0043). In simulations of costs to individuals, the mean estimated lost income associated with severe depression and anxiety disorders was $4,798 per adult per year, after adjustment for age, gender, substance abuse, education, marital status, and household size. Projections of total annual cost to South Africans living with these disorders in lost earnings, extrapolated from the sample, were $3.6 billion. These data indicate either that mental illness has a major economic impact, through the effect of disability and stigma on earnings, or that people in lower income groups are at increased risk of mental illness. The indirect costs of severe depression and anxiety disorders stand in stark contrast with the direct costs of treatment in South Africa, as illustrated by annual government spending on mental health services, amounting to an estimated $59 million for adults. The findings of this study support the economic argument for investing in mental health care as a means of mitigating indirect costs of mental illness.

    South Africa's Constitution guarantees everyone, including persons with disabilities, the right to education. A variety of laws are in place obliging higher education institutions to provide appropriate physical access to education sites for all. In practice, however, many buildings remain inaccessible to people with physical disabilities. To describe what measures South African universities are taking to make their built environments more accessible to students with diverse types of disabilities, and to assess the adequacy of such measures. We conducted semi-structured in-depth face-to-face interviews with disability unit staff members (DUSMs) based at 10 different public universities in South Africa. Challenges with promoting higher education accessibility for wheelchair users include the preservation and heritage justification for failing to modify older buildings, ad hoc approaches to creating accessible environments and failure to address access to toilets, libraries and transport facilities for wheelchair users. South African universities are still not places where all students are equally able to integrate socially. DUSMs know what ought to be done to make campuses more accessible and welcoming to students with disabilities and should be empowered to play a leading role in sensitising non-disabled members of universities, to create greater awareness of, and appreciation for, the multiple ways in which wheelchair user students continue to be excluded from full participation in university life. South African universities need to adopt a systemic approach to inclusion, which fosters an understanding of inclusion as a fundamental right rather than as a luxury.

  2. Proportionality in enterprise development of South African towns

    Directory of Open Access Journals (Sweden)

    Maitland T. Seaman

    2012-05-01

    Full Text Available We investigated proportionalities in the enterprise structures of 125 South African towns through examining four hypotheses, (1 the magnitude of enterprise development in a town is a function of the population size of the town; (2 the size of an enterprise assemblage of a town is a function of the town’s age; (3 there are statistically significant relationships, and hence proportionalities, between the total number of enterprises in towns and some, if not all, of the enterprise numbers of different business sectors in towns; and (4 the implications of proportionalities have far-reaching implications for rural development and job creation. All hypotheses were accepted on the basis of statistically significant (p < 0.05 correlations, except for the second hypothesis – the age of a town does not determine the size of its enterprise assemblage. Analysis for the fourth hypothesis suggested that there are two broad entrepreneurial types in South African towns: ‘run-of-the-mill’ entrepreneurs and ‘special’ entrepreneurs, which give rise to different enterprise development dynamics. ‘Run-of-the-mill’ enterprises are dependent on, and limited by, local demand and if there is only a small demand, the entrepreneurial space is small. By comparison, ‘special’ enterprises have much larger markets because their products and/or services are exportable. We propose that the fostering of ‘special’ entrepreneurs is an imperative for local economic development in South African towns.

  3. The password practices applied by South African online consumers: Perception versus reality

    Directory of Open Access Journals (Sweden)

    Rika Butler

    2015-07-01

    Full Text Available Background: The ability to identify and authenticate users is regarded as the foundation of computer security. Although new authentication technologies are evolving, passwords are the most common method used to control access in most computer systems. Research suggests that a large portion of computer security password breaches are the result of poor user security behaviour. The password creation and management practices that online consumers apply have a direct effect on the level of computer security and are often targeted in attacks. Objectives: The objective of this study was to investigate South African online consumers’ computer password security practices and to determine whether consumers’ perceptions regarding their password security ability is reflected in the password creation and management practices that they apply. Method: A Web-based survey was designed to (1 determine online consumers’ perceptions of their skills and competence in respect of computer password security and (2 determine the practices that South African online consumers apply when creating and managing passwords. The measures applied were then compared to (1 the users’ perceptions about their computer password security abilities and (2 the results of international studies to determine agreement and inconsistencies. Results: South African online consumers regard themselves as proficient password users. However, various instances of unsafe passwords practices were identified. The results of this South African study correspond with the results of various international studies confirming that challenges to ensure safe online transacting are in line with international challenges. Conclusion: There is a disparity between South African online consumers’ perceived ability regarding computer password security and the password creation and management practices that they apply.

    Directory of Open Access Journals (Sweden)

    Ikechukwu O. Ezeuduji

    2017-10-01

    Full Text Available Previous studies have recognised entrepreneurship as a tool capable of driving a nation’s economy. This study explored tourism entrepreneurial intention of South African youth, and analysed relationships between entrepreneurship statements on the one hand, and entrepreneurial intention and entrepreneurial impact on the other hand. A questionnaire survey was used to collect data from simple-randomly selected 220 youth living in Mtubatuba Local Municipality, KwaZulu-Natal Province of South Africa. Descriptive, bivariate and multivariate data analyses yield information to address research objectives. Significant proportion of the youth have entrepreneurial intention, these youth want to solve problems, are willing to pursuing their dreams, have internal locus of control, have positive outlook, have the ability to identify opportunities, and above all have strong sense of empathy. South African Department of Labour needs to develop an operational plan to provide business education, entrepreneurial skills, and relevant support that can empower the youth to start their own businesses. This study validates the alignment of entrepreneurship roles to those of making a difference, innovation, leadership, and self-belief; and shares a positive outlook for the South African economy if the enabling political and economic conditions are created.

    1989-01-01

    Boron, a naturally occuring constituent of surface and ground water, is an essential plant nutrient. However, at relatively low concentrations, boron becomes toxic to plant growth. In order to assess the boron status in South African surface waters, the Department of Water Affairs launched a long-term boron water quality assessment programme in 1985, encompassing the analysis of water samples taken at 91 sites throughout South Africa. Results to date indicate that the boron concentration in South African surface waters varies between 0,02 to 0,33 mg l -1 . At these concentrations even the most boron sensitive crops can be grown without fear of boron toxicity. 3 refs., 1 fig., 2 tabs

    2013-07-03

    South Africa's unique history, characterised by apartheid, a form of constitutional racial segregation and exploitation, and a long period of political violence and state-sponsored oppression ending only in 1994, suggests a high level of trauma exposure in the general population. The aim of this study was to document the epidemiology of trauma and posttraumatic stress disorder (PTSD) in the South African general population. The South African Stress and Health Study is a nationally representative survey of South African adults using the WHO's Composite International Diagnostic Interview (CIDI) to assess exposure to trauma and presence of DSM-IV mental disorders. The most common traumatic events were the unexpected death of a loved one and witnessing trauma occurring to others. Lifetime and 12-month prevalence rates of PTSD were 2.3% and 0.7% respectively, while the conditional prevalence of PTSD after trauma exposure was 3.5%. PTSD conditional risk after trauma exposure and probability of chronicity after PTSD onset were both highest for witnessing trauma. Socio-demographic factors such as sex, age and education were largely unrelated to PTSD risk. The occurrence of trauma and PTSD in South Africa is not distributed according to the socio-demographic factors or trauma types observed in other countries. The dominant role of witnessing in contributing to PTSD may reflect the public settings of trauma exposure in South Africa and highlight the importance of political and social context in shaping the epidemiology of PTSD.

    Cutaneous adverse sequelae of skin lightening creams present with myriad skin complications and affect dermatology practice, particularly in sub-Saharan Africa where such products are widely used, with a prevalence of 25-67%. To examine the skin lightening practices of both African and Indian women living in South Africa. A cross-sectional survey was undertaken in the general outpatient departments of two regional university hospitals in Durban, South Africa. All consenting African and Indian women aged 18-70 years were recruited and asked to complete a questionnaire. Six hundred women completed the questionnaire, of whom 32·7% reported using skin lightening products. The main reasons cited were treatment of skin problems (66·7%) and skin lightening (33·3%). Products were purchased from a variety of sources. Twenty-five percent reported using sunscreen. The use of skin lightening cosmetics is common among darkly pigmented South African women, including those of both African and Indian ancestries. Despite more than 20 years of governmental regulations aimed at prohibiting both the sale of cosmetics containing mercury, hydroquinone and corticosteroids, and the advertising of any kind of skin lightener, they are far from having disappeared. The main motivations for using these products are the desire to treat skin disorders and to achieve a lighter skin colour. Television and magazine advertisements seem to influence women's choice of these products and, thus, would be efficient channels for raising public awareness about the dangers of using uncontrolled skin lighteners. © 2015 The Authors BJD © 2015 British Association of Dermatologists.

    The pervasiveness of tenancy in the postbellum South had countervailing effects on marriage between African Americans. Tenancy placed severe constraints on African American women's ability to find independent agricultural work. Freedwomen confronted not only planters' reluctance to contract directly with women but also whites' refusal to sell land to African Americans. Marriage consequently became one of African American women's few viable routes into the agricultural labor market. We find that the more counties relied on tenant farming, the more common was marriage among their youngest and oldest African American residents. However, many freedwomen resented their subordinate status within tenant marriages. Thus, we find that tenancy contributed to union dissolution as well as union formation among freedpeople. Microdata tracing individuals' marital transitions are consistent with these county-level results.

    Full Text Available Abstract Background In terms of the Nelson Mandela Fidel Castro Medical Collaboration programme, an agreement between the governments of South Africa and Cuba, cohorts of South African students receive their initial five years medical training at a Cuban university before returning to South Africa for a six to twelve months orientation before integration into the local final year class. It is common for these students to experience academic difficulty on their return. Frequently this is viewed merely as a matter of a knowledge deficit. Discussion We argue that the problem arises from a fundamental divergence in the outcomes of the Cuban and South African medical curricula, each of which is designed with a particular healthcare system in mind. Using the discrepancy theory of identity proposed by Higgins in 1987, we discuss the challenges experienced by the returning Nelson Mandela Fidel Castro Medical Collaboration students in terms of a potential crisis of identity and suggest interventions which may prove valuable in promoting academic success and successful integration. Conclusions Though providing additional training to address the gap in skills and knowledge in returning students is an important part of their successful reintegration, this could be insufficient on its own and must be complemented by a range of measures designed to ameliorate the discrepancies in identity which arise from the transition from one educational model to another.

  4. English South African children’s literature and the environment

    Directory of Open Access Journals (Sweden)

    E.R. Jenkins

    2004-07-01

    Full Text Available Historical studies of nature conservation and literary criticism of fiction concerned with the natural environment provide some pointers for the study of South African children’s literature in English. This kind of literature, in turn, has a contribution to make to studies of South African social history and literature. There are English-language stories, poems and picture books for children which reflect human interaction with nature in South Africa since early in the nineteenth century: from hunting, through domestication of the wilds, the development of scientific agriculture, and the changing roles of nature reserves, to modern ecological concern for the entire environment. Until late in the twentieth century the literature usually endorsed the assumption held by whites that they had exclusive ownership of the land and wildlife. In recent years English-language children’s writers and translators of indigenous folktales for children have begun to explore traditional beliefs about and practices in conservation.

  9. Reforming the South African Social Security Adjudication System: Innovative Experiences from South African Non-Social Security Jurisdictions

    Directory of Open Access Journals (Sweden)

    Mathias Ashu Tako Nyenti

    2016-08-01

    Full Text Available There is currently no uniform social security dispute resolution system in South Africa due to the piecemeal fashion in which schemes were established or protection against individual risks regulated. The result is that each statute provides for its own dispute resolution institution(s and processes. There are also various gaps and challenges in the current social security dispute resolution systems, some of these relating to the uncoordinated and fragmented nature of the system; inaccessibility of some social security institutions; inappropriateness of some current appeal institutions; the lack of a systematic approach in establishing appeal institutions; a limited scope of jurisdiction and powers of adjudication institutions; inconsistencies in review and/or appeal provisions in various laws; an unavailability of alternative dispute resolution procedures; and an absence of institutional independence of adjudication institutions or forums. The system is therefore in need of reform. In developing an appropriate system, much can be learned from innovative experiences in comparative South African non-social security jurisdictions on the establishment of effective and efficient dispute resolution frameworks. Dispute resolution systems in the labour relations, business competition regulation and consumer protection jurisdictions have been established to realise the constitutional rights of their users (especially the rights of access to justice, to a fair trial and to just administrative action. They thus provide a benchmark for the development of the South African social security dispute resolution system.

  12. Soft tissue thickness values for black and coloured South African children aged 6-13 years.

    Science.gov (United States)

    2015-07-01

    In children, craniofacial changes due to facial growth complicate facial approximations and require specific knowledge of soft tissue thicknesses (STT). The lack of South African juvenile STT standards of particular age groups, sex and ancestry is problematic. According to forensic artists in the South African Police Service the use of African-American values to reconstruct faces of Black South African children yields poor results. In order to perform a facial approximation that presents a true reflection of the child in question, information regarding differences in facial soft tissue at different ages, sexes and ancestry groups is needed. The aims of this study were to provide data on STT of South African Black and Coloured children and to assess differences in STT with respect to age, sex and ancestry. STT was measured using cephalograms of South African children (n=388), aged 6-13 years. After digitizing the images, STT measurements were taken at ten mid-facial landmarks from each image using the iTEM measuring program. STT comparisons between groups per age, sex and ancestry were statistically analyzed. The results showed that STT differences at lower face landmarks are more pronounced in age groups per ancestry as opposed to differences per age and sex. Generally, an increase in STT was seen between 6-10 year old groups and 11-13 year old groups, regardless of ancestry and sex, at the midphiltrum, labiale inferius, pogonion, and beneath chin landmarks. This research created a reference dataset for STT of South African children of Black and Coloured ancestry per age and sex that will be useful for facial reconstruction/approximation of juvenile remains.

  4. The role of small satellites in the development of the South African space programme

    Science.gov (United States)

    Martinez, Peter

    In the 1990s a team of scientists and engineers at Stellenbosch University built the first South African satellite to fly in space, the 64-kg Sunsat. This university-based satellite programme took advantage of the skills and facilities developed in the previous South African space programme of the 1980s and early 1990s, which had developed a much larger satellite (Greensat), but was cancelled in the mid-1990s prior to launch. Sunsat incorporated a number of novel capabilities for a microsatellite platform, and interest was shown in these technologies by other groups developing similar satellites. As the University was not the ideal environment to develop the commercial potential of these microsatellite technologies, a company called Sunspace was later established, thus creating industrial capacity in South Africa in a niche area of space technology. This new industrial capability, together with the infrastructure from the previous space programme, have created a foundation upon which to build the new South African space programme. This paper discusses the historical, current and possible future roles of small satellites in the development of the South African space programme.

  8. Evaluating research recruitment strategies to improve response rates amongst South African nurses

    2014-03-01

    Research purpose: The aim of this study was to evaluate three research recruitment methods for their impact on recruitment and participation rates amongst South African nurses. Motivation for the study: A limited number of studies exist that formally evaluates different recruitment strategies to improve participation in research amongst nurses within developing contexts, especially South Africa. Research approach, design and method: Participants were recruited using three different methods. Of the 250 nurses randomly selected and invited to participate in a cross-sectional survey, 201 agreed and 162 (81% returned the questionnaires. Main findings: Nursing management participation in the recruitment and data collection process produces more favourable response rates. Reminders and the use of shorter questionnaires also aid higher response rates. Practical/managerial implications: Reminders as well as face-to-face recruitment strategies (especially by a familiar person successfully improved participation rates amongst South African nurses in this study. Contribution/value-add: This study identifies some strategies that could be used more widely to increase the recruitment and participation of South African nurses in research whilst potentially improving their work situation.

    2015-10-01

    Full Text Available This paper examines the nexus of intelligence education and training from a South African perspective with the focus on current practices in light of the country’s transition towards democracy. A brief overview is provided on the history and development of the South African intelligence community with specific focus on the civilian intelligence services from the period prior 1994 to date (2015. The main focus, however, is on intelligence education that is currently available from training institutions and universities in South Africa as registered with the Department of Higher Education as well as private training institutions on the one hand, and the intelligence training practices within the statutory intelligence environment on the other. To this extent, the relations between academic institutions and the intelligence structures in terms of education and training within South Africa are perused against other practices within the African continent and internationally. The approaches to the study of intelligence are also addressed within this paper. Likewise, the how, what as well as to whom – pertaining to intelligence education and training availability and accessibility to students and practitioners within South Africa, is reviewed and analysed with the focus on making recommendations for the enhancement and improvement thereof to enable a focus on preparing the next generation of professional intelligence officers.

This region (which geographically is Federal Region 4) consists of the following eight states: Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee. In order to understand the potential market. A description is provided of the region's energy use, power generation capacity, and potential growth. Highlights of state government activities that could have a bearing on commercial deployment of CCTs are also presented. The potential markets characterized in this summary center on electric power generation by investor-owned, cooperative, and municipal electric utilities and involve planned new capacity additions and actions taken by utilities to comply with Phases I and II of the Clean Air Act Amendments (CAAA) of 1990. Regulations, policies, utility business strategies, and organizational changes that could impact the role of CCTs as a utility option are identified and discussed. The information used to develop the Region 4 Market Description is based mainly on an extensive review of plans and annual reports of 29 investor-owned, cooperative, and municipal coal-using electric utilities and public information on strategies and actions for complying with the CAAA of 1990

    Directory of Open Access Journals (Sweden)

    2011-05-01

    Full Text Available This paper identifies the basic empirical characteristics and changes of the South African business cycle since 1960. As such, the paper examines changes in volatility as well as the co-movement between several national account variables and real GDP. To examine the co-movements the paper follows Kydland and Prescott, Gavin and Kydland as well as Bergman, Bordo and Jonung and uses correlation coefficients and Granger causality tests. Following Ramos, the paper extends the results of the Granger causality tests using variance decomposition analysis in the context of a VAR (vector auto regression to establish the contribution that selected national account variables make to the h-period-ahead forecast error variance of themselves and the other variables included in the VARs. The paper indicates that since 1994 volatility in the South African economy decreased significantly, while durable consumption appears to lead the business cycle.

    Reliable and valid population specific standards are necessary to accurately develop a biological profile, which includes an estimation of peer-reported social identification (Hefner, 2009). During the last 300 years, colonialism, slavery and apartheid created geographic, physical and social divisions of population groups in South Africa. The purpose of this study was to evaluate variation in nasal bone and aperture shape in a modern population of black, white, and coloured South Africans using standard craniometric variables and geometric morphometrics, namely general Procrustes and elliptical Fourier analyses. Fourteen standard landmarks were digitally recorded or computationally derived from 310 crania using a 3D coordinate digitizer for discriminant function, principal components and generalized Procrustes analyses. For elliptical Fourier analysis, outlines of the nasal aperture were generated from standardized photographs. All classification accuracies were better than chance; the lowest accuracies were for coloured and the highest accuracies were for white South Africans. Most difficulties arose in distinguishing coloured and black South African groups from each other. Generally, misclassifications were noted between the sexes within each group rather than among groups, which suggests that sex has less influence on nasal bone and aperture shape than ancestry. Quantifiable variation in shape of the nasal aperture region between white and non-white South African groups was observed. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  9. RECOUNTING STORIES IN SOUTH AFRICAN CHILD WELFARE

    Full Text Available In order to proactively bring about change, it is critical in a post-apartheid context for South African social workers to appreciate how colonial and apartheid forces have shaped the inherited welfare priorities, structures, legislation, policies and practices. It is as necessary also to identify stories of resistance as these offer hope and alternative possibilities. Authors such as McKendrick (2001, Patel (2005 and Loffell (2000 have tracked many aspects of South African welfare history. In its submission to the Truth and Reconciliation Commission – a body set up to formally acknowledge past injustices with the goal of bringing about political reconciliation – the welfare sector set out how it had contributed to historical discrimination and wrongs (Truth and Reconciliation Commission, 1999. While these narratives provide the framework for the development of child welfare in South Africa, relatively little is known about its particular history, especially its earliest roots. Beukes and Gannon (1999 and Allsopp (2005 have attempted to explore the origins of that profession in the child and youth work field. Badroodien (2001 examined the extensive impact of one institution, the Ottery School of Industry, on “coloured” youths and their families. Scordillis and Becker (2005 recount briefly the history of adoption practice in South Africa. Some of the child welfare societies have been able to provide sketches of their agency history. In this article the author attempts to add to the child welfare record, gathering the existing strands of literature and inserting the stories that emerged in her doctoral research (Schmid, 2008b

    It has frequently been argued that the post-apartheid Truth and Reconciliation Commission (TRC) was committed to restorative justice (RJ), and that RJ has deep historical roots in African indigenous cultures by virtue of its congruence both with ubuntu and with African indigenous justice systems......, when the South African Law Commission published an Issue Paper dealing with RJ. Furthermore, I show that neither the connection between RJ and ubuntu nor the connection between RJ and AIJS is as straightforward and unproblematic as often assumed....

  11. The response of South African professional psychology associations to apartheid.

    Professional psychology associations in South Africa have overtly and covertly furthered the aims of apartheid. Guidance about the ethical obligations of psychologists in the South African context has been singularly lacking, and as a result blacks have not been attracted to the profession of psychology in sufficient numbers to administer to psychological needs of the client population. The political dimension of psychological practice in South Africa needs to be addressed directly so that healing strategies relevant to the burgeoning racial conflict in South Africa can be implemented.
