    1994-10-01

    Full Text Available The work being done by the University of Stellenbosch investigating otters as biological indicators of freshwater ecosystem in South Africa is progressing well. The first aim of the project is to assess the role of both species of otter (spotted-necked otters Lutra maculicollis and Cape clawless otters Aonyx capensis in freshwater ecosystems, and the factors and mechanisms responisble for limiting their populations (their role as biological indicators will be inferred from these results and secondly, to contribute to our understanding of carnivore behavioural ecology.The first stage in determining the distribution and status of spotted-necked otters and Cape clawless otters, in South Africa, and possible effects of environmental variants have, is almost complete. A detailed autecological study of Cape clawless otters in two rivers is now the main focus of the project. Six otters have had radio transmitters implanted: MP/300/L, implantable transmitter, 40g 80 x 20 mm diameter cylinder (Telonics Inc., Arizona, USA. Since implanting, one male has died of unknown causes. A post mortem revealed total healing from the operation. Much new behavioural and ecological information has been gained by the use of the radio tracking. One adult male has a home range of at least 45 km, much more than first expected for the species. Work has also been done in the Eastern Cape Province determining the diet of three coexisting carnivores, spotted-necked otters, Cape clawless otters and water mongoose (Atilax paludinosus. This work is about to be submitted for publication. We thank the Southern African Nature Foundation (WWF, for providing funds, and Mazda Wildlife Fund for providing a vehicle for the project.

    2004-01-01

    This paper sets out the reasoning behind the fuzzy set approach to poverty measurement as a means to address both vertical and horizontal vagueness of poverty. The linear approach of Cerioli and Zani and the totally fuzzy and relative approach of Cheli and Lemmi are discussed and applied to the Eastern Cape Province, South Africa, using data from Census 96. The results indicate different experiences of poverty in the Eastern Cape. It is shown that the traditional money metric approach does no...

    Full Text Available Despite the extent of subsistence farmland in Africa, little is known about endangered species that persist within them. The Cape Vulture (Gyps coprotheres is regionally endangered in southern Africa and at least 20% of the population breeds in the subsistence farmland area previously known as the Transkei in the Eastern Cape province of South Africa. To understand their movement ecology, adult Cape Vultures (n = 9 were captured and fitted with global positioning system/global system for mobile transmitters. Minimum convex polygons (MCPs,and 99% and 50% kernel density estimates (KDEs were calculated for the breeding and non breeding seasons of the Cape Vulture. Land use maps were constructed for each 99% KDE and vulture locations were overlaid. During the non-breeding season, ranges were slightly larger(mean [± SE] MCP = 16 887 km2 ± 366 km2 than the breeding season (MCP = 14 707 km2 ± 2155 km2. Breeding and non-breeding season MCPs overlapped by a total of 92%. Kernel density estimates showed seasonal variability. During the breeding season, Cape Vultures used subsistence farmland, natural woodland and protected areas more than expected. In the non-breeding season, vultures used natural woodland and subsistence farmland more than expected, and protected areas less than expected. In both seasons, human-altered landscapes were used less, except for subsistence farmland.Conservation implications: These results highlight the importance of subsistence farm land to the survival of the Cape Vulture. Efforts should be made to minimise potential threats to vultures in the core areas outlined, through outreach programmes and mitigation measures.The conservation buffer of 40 km around Cape Vulture breeding colonies should be increased to 50 km.

    2016-03-01

    Full Text Available This paper interrogates the geography of tourism innovation in the Western Cape, South Africa. In particular, innovations by tourism firms are mapped and local tourism innovation networks are analysed. Networking behaviour is examined since it is regarded as indispensable for accessing knowledge and learning for innovation purposes. The analysis draws on a broader investigation of tourism innovation and networking within the Western Cape province. It is revealed that the main tourist regions in the Western Cape are also the most innovative. Whilst external networking relations are observed to be highly significant for tourism innovation, local embeddedness remains critical for stimulating path creation and exploiting local core competencies for the competitiveness and survival of tourism firms and destinations.

    Full Text Available An outbreak of annual ryegrass toxicity occurred on a Thoroughbred stud in Ceres in the Western Cape Province of South Africa. This is the 1st report of annual ryegrass toxicity in horses in South Africa, although the condition has been reported in cattle and sheep populations in the past. Annual ryegrass toxicity is characterised by a variety of neurological signs including tremors, convulsions, recumbency and in many cases death. The description of the outbreak includes the history, clinical presentation and treatment protocol administered during the outbreak. Various epidemiological variables and their influence in the outbreak are also considered.

  8. The geology of the area south of Vioolsdrif, Cape Province

    International Nuclear Information System (INIS)

    Geological reconnaissance of an area of 1 500 square km to the South of Vioolsdrif in northern Namaqualand has revealed that this region straddles the boundary between the upper crustal Richtersveld domain and the subjacent Namaqualand Metamorphic Complex. The Vioolsdrif batholith, which underlies much of the Richtersveld, is a composite body, essentially granodioritic, which was emplaced in a number of epizonal magmatic pulses into an overlying comagmatic canopy of intermediate to felsic lavas and pyroclastics during Bushveld times. It is unlikely that this volcanic carapace exceeded 9 km in thickness. During or following consolidation at about 1 800 Ma, the southern margin of the batholith was affected by a thermotectonic episode of regional extent during which the rocks of the igneous complex were foliated and lineated in sympathy with the dominant tectonic fabric of the contiguous metamorphic complex. Metamorphic mineral parageneses indicate that during the climax of this dynamothermal episode, rocks along the southern margin of the batholith were subjected to temperatures of 620 - 670 degrees and pressures of 0,4 - 0,5 MPa (4 - 5 kbar). During this deformational episode the batholith acted as a tectonic resister which preserved the overlying volcanics from incorporation into the metamorphic complex. More or less coincident with the boundary between the metamorphic complex and the Vioolsdrif batholith is a zone about 10 km in width which is characterised by the development of abundant pegmatites

    1983-12-01

    Full Text Available Floristic and structural features of the three main vegetation types found in the coastal foreland of the western Cape Province, south of the Berg River, are outlined. Coastal Renosterveld. which occupies 6% of its former extent, is the most threatened type, followed by Coastal Fynbos (14% and West Coast Strandveld (41%. Coastal Renosterveld is closely related to Mountain Fynbos vegetation found on clay-rich soils together with West Coast Strandveld inclusions in specific habitats. Coastal Renosterveld is the product of recent regular disturbance by a short interval burning regime and overgrazing.

  10. Erosion-land use change-climate change nexus in the Eastern Cape Province, South Africa

    Kakembo, Vincent

    2016-04-01

    Unlike many parts of the world where land recovery has been realised as a response to less dependence on land for a livelihood, soil erosion - mainly on abandoned cultivated and overgrazed communal lands in the Eastern Cape Province of South Africa - has intensified. Land abandonment is attributed by most elderly land users to drought that hit the area in the 1960s. The interaction among land-degradation drivers - ranging from soil properties, topography, land-use changes and vegetation to local climate - has given rise to a self-amplifying land degradation feedback loop that has perpetuated severe forms of soil erosion. This has rendered the degraded areas particularly vulnerable to climate change impacts on water. The perpetual degradation calls for developing a dedicated policy on the management and rehabilitation of eroded lands. Restoration approaches should entail promoting disconnectivity on eroded hillslopes. Communal farmers also have to be sensitised and empowered to take ownership of the land-restoration process.

    Full Text Available Background: South Africa (SA is experiencing a rapid epidemiologic transition as a consequence of political, economic and social changes. In this study we described, based on hospital data, the mortality patterns of Non communicable Diseases (NCD, Communicable Diseases (CD, the NCD/CD ratios, and the trends of deaths.Methods: We conducted a cross-sectional survey of all deaths occurring in several public hospitals in the Eastern Cape Province of SA between 2002 and 2006. Causes of deaths were coded according to the ICD 10 Edition.Results: A total of 107380 admissions responded to the inclusion criteria between 2002 and 2006. The crude death rate was 4.3% (n=4566 with a mean age of 46±21 years and a sex ratio of 3.1 men (n=3453: 1 woman (n=1113. Out of all deaths, there were 62.9% NCD (n=2872 vs. 37.1% CD (n=1694 with NCD/CD ratio of 1.7. The ratio NCD/CD deaths in men was 1.3 (n=1951/1502 vs. NCD/CD deaths in women of 1.9 (n=735/378. The peak of deaths was observed in winter season. The majority of NCD deaths were at age of 30-64 years, whereas the highest rate of CD deaths was at age< 30 years. The trend of deaths including the majority of NCD, increased from 2002 to 2006. There was a tendency of increase in tuberculosis deaths, but a tendency of decrease in HIV/AIDS deaths was from 2002 to 2006.Conclusion: Non-communicable diseases are the leading causes of deaths in rural Eastern Cape province of SA facing Post-epidemiologic transition stages. We recommend overarching priority actions for the response to the Non-communicable Diseases: policy change, prevention, treatment, international cooperation, research, monitoring, accountability, and re-orientation of health systems.

    2010-05-01

    Full Text Available Rabies is a growing problem in the Eastern Cape Province of South Africa. This study investigated dog ecology, vaccination coverage and rabies neutralising antibody levels in 203 randomly selected dogs within a local municipality in the former Transkei area. Responses to vaccination were also evaluated in 80 of these dogs. The population was remarkably uniform in size, breed and condition. Slightly over 1/5th of the population was between 6 weeks and 1 year of age, while very few dogs reached 10 years or older. According to owner responses, the Animal Health Technicians achieved a total vaccination coverage of 65 % of owned dogs over several years, but only 56 % within the previous 12 months. Only 32%of dogs had adequate circulating rabies virus neutralisation antibodies (≥0.5IU/ℓ. After vaccination, 83 % had seroconverted to this level. The magnitude of seroconversion was independent of body condition or age. This study proposes a different approach to vaccination strategies than those currently employed in certain areas of the province.

    2010-11-01

    Full Text Available Palystes kreutzmanni sp. n. is described from habitats close to Kleinmond, in the Western Cape Province, South Africa. Spiders of this new species live in the typical fynbos vegetation of the Western Cape region. They build retreats between apical leaves of Leucadendron bushes. The systematic position of P. kreutzmanni sp. n. is discussed. Male and female show characters of different species groups, especially the female copulatory organ seems to be unique within the genus Palystes L. Koch, 1875.

    Full Text Available Notwithstanding the growing interest in business incubation programmes and the benefits derived from such programmes, the path is beset by numerous challenges. This paper investigates the challenges faced by business incubators (BIs as they strive to support their clients. The study utilized a qualitative approach to collect data by way of interviews to gain in-depth knowledge and understanding of the concept and challenges of business incubators. The data were collected using structured and unstructured in-depth personal interviews, which were carried out with the respondents of business incubators in the Western Cape. The research participants for this study were limited to the business incubators on the database of a local organization that promotes small and medium enterprises (SMEs development strategy and programmes in the Western Cape Province. All five business incubators on the database were deemed suitable for the study. The results indicated that an average of twenty-five entrepreneurs graduated from the incubation programme in the last five years. Furthermore, lack of sponsorship, production space, advanced technological facilities (prototype and expansion to different areas were found to be among the challenges hindering incubators.

    ASTRACT The development of national food security information systems is constrained by a lack of guidance on which indicators to use. This paper compares food security indicators across two seasons (summer and winter) in one of the most deprived areas of the Eastern Cape province of South Africa. The results show that only anthropometric indicators are sensitive enough to differentiate levels of food insecurity. The lack of consistent classification across indicators means that surveys must use a combination of food consumption and experience of hunger measures backed up by anthropometric measures. Targeting interventions is difficult if the measures cannot be relied on. Further investigation is needed to identify a suite of appropriate indicators for a national information and surveillance system. PMID:26789552

    Full Text Available Abstract Background South Africa is one of the major users of pesticides on the African continent. The Eastern Cape is the second largest province in South Africa. There has been growing concern about the occurrence of certain birth defects which seemed to have increased in the past few years. In this paper we investigate associations between exposure to agricultural chemicals and certain birth defects. Few such studies have been undertaken in the developing world previously. Methods Between September 2000 and March 2001 a case – control study was conducted among rural women in the area of the Eastern cape to investigate the association between women's exposure to pesticides and the occurrence of birth defects. Information on birth defects was obtained from the register of the Paediatrics Department at the Cecilia Makiwane Hospital in Mdantsane, one of the largest referral hospitals in the province. The cases were children who were diagnosed with selected birth defects. The controls were children born in the same areas as the cases. Exposure information on the mothers was obtained by interview concerning from their activities in gardens and fields. Data were analysed using conditional logistic regression. Results A total of 89 case mothers and 178 control mothers was interviewed. Babies with birth defects were seven times more likely to be born to women exposed to chemicals used in gardens and fields compared to no reported exposure (Odds Ratio 7.18, 95% CI 3.99, 13.25; and were almost twice as likely to be born to women who were involved in dipping livestock used to prevent ticks (OR 1.92, 95% CI 1.15, 3.14. They were also 6.5 times more likely to be born to women who were using plastic containers for fetching water (OR 6.5, 95% CI 2.2, 27.9. Some of these containers had previously contained pesticides (OR 1.87, 95% CI 1.06, 3.31. Conclusions These findings suggest a link between exposure to pesticides and certain birth defects among the

  4. Ultrastructural micromorphology of bulbine abyssinica A. rich. growing in the eastern cape province, south africa

    International Nuclear Information System (INIS)

    The genus Bulbine (Asphodelaceae) comprises about 40 species in South Africa. Bulbine abyssinica is a succulent member of the genus that occurs from the Eastern Cape, through Swaziland, Lesotho, and further north to Ethiopia. The species is often used in traditional medicine to treat rheumatism dysentery, bilharzia and diabetes. Inspite of its ethno medicinal value, not much data concerning the micro-morphological features is available in literature. The present study was undertaken to examine the ultra-morphological features of the leaf, stem and root of the plant using light and scanning electron microscopes and the elemental composition. The elemental compositions of the plant parts were done using energy dispersive x- ray spectroscopy. The mean length and width of the guard cells in the abaxial surface are 0.15 ± 0.002 mm and 0.14 ± 0.002 mm, respectively while those of the adaxial surface are 0.14 ± 0.001 mm and 0.12 ± 0.001 mm, respectively. The electron microscopy revealed the presence of crystals in the leaves, stems and roots. The EDXS microanalysis of the crystals revealed the presence of sodium, silicon, potassium and calcium as the major constituents. The leaf also showed the presence of iron and magnesium, while the stem had aluminium, phosphorous and magnesium. The X-ray analysis of the roots also revealed the presence of sulphur and aluminium. The presence of these elements, which are vital in maintaining good health status, suggests the potential role of B. abyssinica in the treatment of infections and some chronic diseases, especially diabetes mellitus.

    Full Text Available Drought is a major disaster in South Africa in terms of total economic loss and number of people affected. This study investigated and analysed the preparedness, impact of and response by the farming community to the 2007/2008 drought using the Eastern Cape and Free State provinces of South Africa as case studies. Both qualitative and quantitative approaches were used in this study. Primary data were collected through face-to-face interviews with sampled recipients of the 2007/2008 drought relief scheme. These were analysed using MedCalc® software and various statistical tests and correlations were performed to test for statistical differences on key variables. Major findings of this study included inadequacy of the extension support service, particularly as a vehicle for disseminating early-warning information. The most significant impact was livestock losses, and t-test results supported the hypothesis that there was a significant difference in terms of drought impact for the three categories of farmers (i.e. small, medium and large scale, particularly with regard to the proportion of livestock lost. A Logit analysis showed that the decision to reduce livestock during drought was influenced by access to land and race. The main constraint to the drought relief scheme, as perceived by the respondents, was the turnaround time − they felt that the relief was provided long after the disaster had occurred.

  7. Accuracy of serological testing for the diagnosis of prevalent neurocysticercosis in outpatients with epilepsy, Eastern Cape Province, South Africa.

    Directory of Open Access Journals (Sweden)

    Humberto Foyaca-Sibat

    Full Text Available BACKGROUND: Few studies have estimated prevalence of neurocysticercosis (NCC among persons with epilepsy in sub-Saharan Africa. While the limitations of serological testing in identification of NCC are well known, the characteristics of persons who are misdiagnosed based on serology have not been explored. The first objective of this pilot study was to estimate the prevalence of NCC in epilepsy outpatients from an area of South Africa endemic for cysticercosis. The second objective was to estimate the accuracy of serological testing in detecting NCC in these outpatients and characterize sources of disagreement between serology and neuroimaging. METHODOLOGY/PRINCIPAL FINDINGS: All out-patients aged 5 or older attending the epilepsy clinic of St. Elizabeth's Hospital in Lusikisiki, Eastern Cape Province, between July 2004 and April 2005 were invited to participate. Epidemiological data were collected by local study staff using a standardized questionnaire. Blood samples were tested by ELISA for antibody and antigen for Taenia solium. Four randomly chosen, consenting participants were transported each week to Mthatha for brain CT scan. The proportion of persons with epilepsy attending St. Elizabeth clinic with CT-confirmed NCC was 37% (95% CI: 27%-48%. Using CT as the gold standard, the sensitivity and specificity of antibody testing for identifying NCC were 54.5% (36.4%-71.9% and 69.2% (52.4%-83.0%, respectively. Sensitivity improved to 78.6% (49.2%-95.3% for those with active lesions. Sensitivity and specificity of antigen testing were considerably poorer. Compared to false negatives, true positives more often had active lesions. False positives were more likely to keep pigs and to have seizure onset within the past year than were true negatives. CONCLUSIONS/SIGNIFICANCE: The prevalence of NCC in South African outpatients with epilepsy is similar to that observed in other countries where cysticercosis is prevalent. Errors in classification of NCC

  8. Biogeography and molar morphology of Pleistocene African elephants: new evidence from Elandsfontein, Western Cape Province, South Africa

    Science.gov (United States)

    Smith, Kathlyn M.; Stynder, Deano D.

    2015-05-01

    Elandsfontein (EFT) is a Middle Pleistocene archaeological/paleontological site located in the Western Cape Province of South Africa. The largest herbivore in the assemblage is Loxodonta atlantica zulu, an extinct member of the genus that includes modern African elephants. No Elephas recki specimens were recovered at EFT, despite their common occurrence in other regions of Africa at the same time. Because E. recki and L. atlantica molars are similar in appearance, but the two species are traditionally viewed as dominating different regions of Africa during the Pleistocene, isolated molars may on occasions have been assessed to species level on the basis of geography rather than morphology. The last morphologic evaluation of EFT elephants was conducted in the 1970s, and revisiting this issue with new specimens provides added insight into the evolution of elephants in Africa. Reevaluating morphological characteristics of EFT elephant molars, through qualitative and quantitative description and comparison with Middle Pleistocene E. recki recki, L. atlantica atlantica, and L. atlantica zulu molar morphology, corroborates assessment of EFT elephants as L. a. zulu. Two recently discovered, previously undescribed molars from EFT show that molars of L. a. zulu exhibit greater variation in enamel thickness, lamellar frequency, and occlusal surface morphology than previously reported. An update of the Pleistocene biogeography of Loxodonta and Elephas indicates that fossil remains of both are often found at the same localities in eastern Africa. Their rare co-occurrences in the north and south, however, suggest geographic separation of the two genera in at least some regions of Africa, which may have been based on habitat preference.

    Full Text Available Protected areas globally are threatened by the potential negative impacts that invasive alien plants pose, and Camdeboo National Park (CNP, South Africa, is no exception. Alien plants have been recorded in the CNP since 1981, before it was proclaimed a national park by South African National Parks in 2005. This is the first publication of a list of alien plants in and around the CNP. Distribution maps of some of the first recorded alien plant species are also presented and discussed. To date, 39 species of alien plants have been recorded, of which 13 are invasive and one is a transformer weed. The majority of alien plant species in the park are herbaceous (39% and succulent (24% species. The most widespread alien plant species in the CNP are Atriplex inflata (= A. lindleyi subsp. inflata, Salsola tragus (= S. australis and cacti species, especially Opuntia ficus-indica. Eradication and control measures that have been used for specific problematic alien plant species are described. Conservation implications: This article represents the first step in managing invasive alien plants and includes the collation of a species list and basic information on their distribution in and around the protected area. This is important for enabling effective monitoring of both new introductions and the distribution of species already present. We present the first species list and distribution information for Camdeboo National Park.

    Full Text Available The prevalence and geographic distribution of the fowl tampan, Argas walkerae Kaiser & Hoogstraal, 1969 was determined in the eastern region of the Eastern Cape Province, South Africa by inspecting two fowl houses in the vicinity of each of 72 randomly selected communal cattle dip-tanks. Tampans were collected from 102 (70.8 % of the 144 fowl houses in the neighbourhood of 57 (79.2 % of the 72 selected dip-tanks, and the localities of the collections were mapped. Argas walkerae was present in fowl houses from the warm coastal regions of the Indian Ocean in the south to the cold and mountainous Drakensberg in the north-east of the Province. Taking into account the probable sensitivity of the sampling method, it is estimated that A. walkerae is likely to be present in fowl houses belonging to between 74 and 84 % of communities making use of cattle dip-tanks in the eastern region of the Eastern Cape Province, and that when it is present, between 64 and 75 % of fowl houses will be infested. The geographic distribution of A. walkerae seemed to be more strongly associated with the presence of fowls and fowl houses containing raw or processed wood in their structure than with climate.

    The exposure of farm animals to antimicrobials for treatment, prophylaxis, or growth promotion can select for resistant bacteria that can be transmitted to humans, and Salmonella as an important zoonotic pathogen can act as a potential reservoir of antimicrobial resistance determinants. We assessed the antibiogram profiles of Salmonella species isolated from pig herds in two commercial farms in South Africa. Two hundred fifty-eight presumptive Salmonella isolates were recovered from the fecal samples of 500 adult pigs. Specific primers targeting Salmonella serogroups A, B, C1, C2, and D were used to determine the prevalence of different serogroups. Only serogroup A (n = 48) was detected, while others were not. Antimicrobial susceptibility of the confirmed Salmonella serogroup A isolates was performed by using the disk diffusion method against a panel of 18 antibiotics. All the 48 isolates were resistant to tetracycline and oxytetracycline, while 75% were resistant to ampicillin, sulphamethoxazole-trimethoprim, nalidixic acid, and streptomycin. All the isolates exhibited multidrug resistance, with the predominant phenotype being against 11 antibiotics, and multiple antibiotic resistance index ranged between 0.3 and 0.6. The incidence of genes encoding resistance against ampicillin (ampC), tetracycline (tetA), and streptomycin (strA) were 54, 61, and 44%, respectively. We conclude that healthy pigs are potential reservoirs of multidrug-resistant Salmonella that could be transmitted to humans through the food chain and, hence, a significant public health threat.

    Full Text Available Soil-inhabiting nematodes, including plant-parasitic nematodes, are considered to be the most abundant multicellular organisms in the soil, and of particular interest since they are an integral part of the interlocking chain of nutrient conversions. Because of their abundance and relative susceptibility to both physical and chemical changes, these organisms are used as indicator organisms. The National Collection of Nematodes (NCN consists of a core collection, the Meloidogyne Collection and the Juan Heyns Collection, which are housed at the Plant Protection Research Institute of the Agricultural Research Council in Pretoria. Vast amounts of biodiversity data are contained in NCN, and the digitising of the collection from 2007 to 2014 yielded unpublished locality information, especially datasets of plant nematodes reported from protected areas of the Eastern Cape. Two hundred and thirty plant nematode species belonging to 36 genera were reported from the Eastern Cape. Of these, only 80 were from protected areas, whilst 163 were from uncultivated areas (outside protected areas and 148 from cultivated areas. Ten species were described from protected areas, namely Criconemoides silvicola, Meloinema silvicola, Ogma tuberculatum, Paralongidorus cebensis, Paralongidorus hanliae, Scutellonema tsitsikamense, Trichodorus vandenbergae, Xiphinema erriae, Xiphinema ornatizulu and Xiphinema simplex. Only M. silvicola, O. tuberculatum, P. cebensis and S. tsitsikamense were not reported from other provinces, suggesting endemism.Conservation implications: The diversity of nematode fauna is not adequately protected as most nematode biodiversity in the Eastern Cape lies outside protected areas, with only 80 of the 230 plant-feeding nematode species in the province being reported from protected areas.

    Sibewu, M.; Momba, M. N. B.; Okoh, A. L.

    This study focuses on the assessment of the protozoan fauna and abundance in the mixed liquors of aeration tanks of the three municipal wastewater treatment plants located in Fort Beaufort, Dimbaza and East London in the Eastern Cape Province of South Africa and their implication to the production of effluents of good quality. The samples were collected between September and December 2005 and protozoa species were identified by direct microscopic observations at x400 magnification by comparison with existing protozoa gallery collections. A total of 68 protozoan genera made up of 44 ciliates, 16 flagellates and 8 others were identified in wastewater treatment plants. Although in all aerobic zones the average density of ciliates was 104 cells mL-1, which indicated that these plants were able to produce clear effluent of good quality, a better performance was found in Dimbaza and East London, which had total protozoan genera of 27 and 26, respectively.

    With few exceptions, immunization supply chains in developing countries continue to face chronic difficulties in providing uninterrupted availability of potent vaccines up to service delivery levels, and in the most efficient manner possible. As these countries struggle to keep pace with an ever growing number of vaccines, more and more Ministries of Health are considering options of engaging the private sector to manage vaccine storage, handling and distribution on their behalf. Despite this emerging trend, there is limited evidence on the benefits or challenges of this option to improve public supply chain performance for national immunization programmes. To bridge this knowledge gap, this study aims to shed light on the value proposition of outsourcing by documenting the specific experience of the Western Cape Province of South Africa. The methodology for this review rested on conducting two key supply chain assessments which allowed juxtaposing the performance of the government managed segments of the vaccine supply chain against those managed by the private sector. In particular, measures of effective vaccine management best practice and temperature control in the cold chain were analysed. In addition, the costs of engaging the private sector were analysed to get a better understanding of the economics underpinning outsourcing vaccine logistics. The results from this analysis confirmed some of the theoretical benefits of outsourcing to the private sector. Yet, if the experience in the Western Cape can be deemed a successful one, there are several policy and practice implications that developing countries should be mindful of when considering engaging the private sector. While outsourcing can help improve the performance of the vaccine supply chain, it has the potential to do the reverse if done incorrectly. The findings and lessons learnt from the Western Cape experience can serve as a step towards understanding the role of the private sector in immunization

    Objectives The aim of this study was to explore and understand women's pathways to breast cancer diagnosis and factors influencing this journey. Design and setting Indepth interviews were conducted with clients at a tertiary level breast cancer clinic in Cape Town, South Africa. A thematic analysis was performed underpinned by the theoretical concepts of the Model of Pathways to Treatment framework. Participants 20 women were interviewed within 1 week of being diagnosed with breast cancer. Results The average time between discovery of bodily changes to breast cancer diagnosis was 8.5 months. Deficits in breast self-awareness and knowledge of breast cancer symptoms delayed women's interpretation of bodily changes as being abnormal. All women first noticed breast lumps; however, many did not perceive it as abnormal until additional symptoms were present. General good health, attribution of symptoms to ageing, and past benign breast disease resulted in women being complacent about bodily changes. Disclosure to family members served as a trigger to seek healthcare. The initial type of primary level care services women accessed was influenced by perceptions of care each service provided, finances, structural factors, and personal safety related to the physical location of services. Conclusions Symptom appraisal and interpretation contributed significantly to delayed presentation. To improve timely diagnosis of breast cancer, interventions that increase women's confidence in detecting breast changes, improve knowledge of breast cancer symptoms, address myths, and encourage prompt help-seeking behaviour are required.

    Full Text Available Abstract Background Amidst an evolving post-apartheid policy framework for health, policymakers have sought to institutionalize community participation in Primary Health Care, recognizing participation as integral to realizing South Africa’s constitutional commitment to the right to health. With evolving South African legislation supporting community involvement in the health system, early policy developments focused on Community Health Committees (HCs as the principal institutions of community participation. Formally recognized in the National Health Act of 2003, the National Health Act deferred to provincial governments in establishing the specific roles and functions of HCs. As a result, stakeholders developed a Draft Policy Framework for Community Participation in Health (Draft Policy to formalize participatory institutions in the Western Cape province. Methods With the Draft Policy as a frame of analysis, the researchers conducted documentary policy analysis and semi-structured interviews on the evolution of South African community participation policy. Moving beyond the specific and unique circumstances of the Western Cape, this study analyzes generalizable themes for rights-based community participation in the health system. Results Framing institutions for the establishment, appointment, and functioning of community participation, the Draft Policy proposed a formal network of communication – from local HCs to the health system. However, this participation structure has struggled to establish itself and function effectively as a result of limitations in community representation, administrative support, capacity building, and policy commitment. Without legislative support for community participation, the enactment of superseding legislation is likely to bring an end to HC structures in the Western Cape. Conclusions Attempts to realize community participation have not adequately addressed the underlying factors crucial to promoting

    Full Text Available As part of the South African National Survey of Arachnida (SANSA in conserved areas, arachnids were collected in the De Hoop Nature Reserve in the Western Cape Province, South Africa. The survey was carried out between 1999 and 2007, and consisted of five intensive surveys between two and 12 days in duration. Arachnids were sampled in five broad habitat types, namely fynbos, wetlands, i.e. De Hoop Vlei, Eucalyptus plantations at Potberg and Cupido’s Kraal, coastal dunes near Koppie Alleen and the intertidal zone at Koppie Alleen. A total of 274 species representing five orders, 65 families and 191 determined genera were collected, of which spiders (Araneae were the dominant taxon (252 spp., 174 genera, 53 families. The most species rich families collected were the Salticidae (32 spp., Thomisidae (26 spp., Gnaphosidae (21 spp., Araneidae (18 spp., Theridiidae (16 spp. and Corinnidae (15 spp.. Notes are provided on the most commonly collected arachnids in each habitat.Conservation implications: This study provides valuable baseline data on arachnids conserved in De Hoop Nature Reserve, which can be used for future assessments of habitat transformation, alien invasive species and climate change on arachnid biodiversity.

    Full Text Available South Africa has the largest worldwide HIV/AIDS population with 5.6 million people infected and at least 2 million people on antiretroviral therapy. The majority of these infections are caused by HIV-1 subtype C. Using genotyping methods we characterized HIV-1 subtypes of the gag p24 and pol PR and RT fragments, from a cohort of female participants in the Western Cape Province, South Africa. These participants were recruited as part of a study to assess the combined brain and behavioural effects of HIV and early childhood trauma. The partial HIV-1 gag and pol fragments of 84 participants were amplified by PCR and sequenced. Different online tools and manual phylogenetic analysis were used for HIV-1 subtyping. Online tools included: REGA HIV Subtyping tool version 3; Recombinant Identification Program (RIP; Context-based Modeling for Expeditious Typing (COMET; jumping profile Hidden Markov Models (jpHMM webserver; and subtype classification using evolutionary algorithms (SCUEAL. HIV-1 subtype C predominates within the cohort with a prevalence of 93.8%. We also show, for the first time, the presence of circulating BC strains in at least 4.6% of our study cohort. In addition, we detected transmitted resistance associated mutations in 4.6% of analysed sequences. With tourism and migration rates to South Africa currently very high, we are detecting more and more HIV-1 URFs within our study populations. It is still unclear what role these unique strains will play in terms of long term antiretroviral treatment and what challenges they will pose to vaccine development. Nevertheless, it remains vitally important to monitor the HIV-1 diversity in South Africa and worldwide as the face of the epidemic is continually changing.

    Full Text Available African Horsesickness (AHS is a controlled disease in South Africa. The country is divided into an infected area and a control area. An outbreak of AHS in the control area can result in a ban of exports for at least 2 years. A retrospective epidemiological study was carried out on data collected during the 2004 AHS outbreak in the surveillance zone of the AHS control area in the Western Cape Province. The objective of this study was to describe the 2004 outbreak and compare it with the 1999 AHS outbreak in the same area. As part of the investigation, a questionnaire survey was conducted in the 30 km radius surrounding the index case. Spatial, temporal and population patterns for the outbreak are described. The investigation found that the outbreak occurred before any significant rainfall and that the main AHS vector (Culicoides imicola was present in abundance during the outbreak. Furthermore, 63% of cases occurred at temperatures < 15 oC, the Eerste River Valley was a high risk area, only 17% of owners used vector protection as a control measure and 70% of horses in the outbreak area were protected by means of vaccination at the start of the outbreak. The study revealed that the current AHS control measures do not function optimally because of the high percentage of vaccinated horses in the surveillance zone, which results in insufficient sentinel animals and the consequent failure of the early warning system. Alternative options for control that allow continued export are discussed in the paper.

    Full Text Available Oxidized low-density lipoprotein (ox-LDL is a powerful natural prooxidant derived from native LDL by cell-mediated oxidation. Such oxidation occurs more easily in glycated LDL as observed in diabetes mellitus. We evaluated and compared selected biomarkers of oxidative stress and total antioxidant (TAO levels in type 2 diabetes mellitus (T2DM patients with and without retinopathy in the Mthatha region of the Eastern Cape Province, South Africa. The participants totaled to 140 and this number comprised 98 diabetic patients on treatment, stratified by diabetes (54 and diabetes with retinopathy (44. Forty-two nondiabetic healthy controls made up the 140. Fasting plasma glucose (FPG, glycosylated hemoglobin (HbA1c, lipid profile, serum ox-LDL, thiobarbituric acid reactive substances (TBARS, and TAO levels were measured. A statistically significant increase in FPG, HbA1c, TBARS, and ox-LDL and a significant decrease in TAO levels were seen in T2DM patients with retinopathy as compared to controls. A significant negative correlation was observed between TAO and ox-LDL levels in the diabetic group. In multiple linear regression analyses, duration of diabetes, triglyceride, TAO, and LDL cholesterol were found to be significantly associated with ox-LDL. In multiple logistic regression analyses, ox-LDL [OR 1.02 (1.01–1.03, P=0.005] was the only risk factor and was significantly associated with the presence of retinopathy.

    2015-08-01

    Full Text Available Over a period of three years, 360 teachers at 26 resource constrained schools in Cofimvaba, which lies in the Nciba district of the Eastern Cape Province of South Africa, have received training on how to integrate mobile tablets in their classrooms to support teaching and learning. The training modules combined the use of teaching strategies and fun with practical hands-on exercises which can be used in any type of subject for any grade when training teachers. Teachers embarked on a learning path attached to badges to reward their efforts and evidence of how they have applied their training in their classrooms. The purpose of this paper is to share this novel approach to teacher training in a unique context where schools are deprived of resources but still managed to successfully integrate mobile tablets in their classroom practices. These practices have changed the way teachers teach from standing with a textbook and chalk in front of a class sitting in rows, to standing with a tablet and learners are engaged in group work and using the tablets as a resource in a disconnected environment. The success of these training modules lies in the application of an approach of teach with and not to, earn as you learn and not just give technology, respect and humility, flexibility, innovation, creativity and co-creation.

    Pyrosequencing targeting the V1-V3 hypervariable of the 16S rDNA was used to investigate the bacterial diversity in river and roof-harvested rainwater (RHRW) used for potable purposes by rural households in Luthengele village in the Eastern Cape Province of South Africa. The phylum Proteobacteria dominated the data set (80.5 % of all reads), while 4.2 % of the reads could not be classified to any of the known phyla at a probability of 0.8 or higher (unclassified bacteria). At class level, the classes; Betaproteobacteria (50.4 % of all reads), Alphaproteobacteria (16.2 %), Verrucomicrobiae (6.6 %), Planctomycetacia (5.7 %), and Sphingobacteria (3 %) dominated the data set in all the samples. Although the class Verrucomicrobiae constituted 6.6 % of all sequences, 88.6 % of the sequences were from the river sample where the class represented 43.7 % of the observed sequences in the sample. The bacteria community structure clearly showed significant similarities between RHRW and differences with the river water control sample, suggesting different levels of contamination and environmental factors affecting the various water sources. Moreover, signatures of potential pathogens including Legionella, Acinetobacter, Pseudomonas, Clostridia, Chromobacterium, Yersinia, and Serratia were detected, and the proportions of Legionella were relatively higher suggesting a potential health risk to households using RHRW. This work provides guidance for prioritizing subsequent culturable and quantitative analysis to ensure that potentially significant pathogens are not left out of risk estimations. PMID:25637385

    Full Text Available Pseudomonas species are opportunistic pathogens with implications in a wide range of diseases including cystic fibrosis and sickle cell anaemia. Because of their status as multidrug resistant (MDR and extremely drug resistant (XDR bacteria Pseudomonas species represent a threat to public health. Prevalence, antibiogram and associated antibiotic resistant genes of Pseudomonas species isolated from freshwater and mixed liquor environments in the Eastern Cape Province of South Africa were assessed. Polymerase chain reaction (PCR based technique was used to identify the isolates and screen for antibiotic resistant genes. The result shows occurrence of Pseudomonas spp. in freshwater and mixed liquor as follows: 71.42% and 37.5% (P. putida, 14.28% and 31.25% (P. flourescens, 7.14% and 6.25% (P. aeruginosa and 7.14% and 25% for other Pseudomonas species respectively. Disk diffusion antibiogram of the Pseudomonas isolates from the two locations showed 100% resistance to penicillin, oxacillin, clindamycin, rifampicin and 100% susceptibility to ciprofloxacin and gentamicin with varied percentage resistances to cephalothin, nalidixic acid, tetracycline, and ampicillin. The blaTEM antibiotic resistant gene was detected in 12.5% of P. putida, 57.14% of P. fluorescens, 100% P. aeruginosa and 40% in other Pseudomonas species. Similarly, Integrons conserved segment were detected in 12.5% of P. putida, 57.14% of P. fluorescens, 100% of P. aeruginosa and 40% of other Pseudomonas species. The presence of blaTEM gene and integrons conserved segment in some of the isolates is worrisome and suggest Pseudomonas species as important reservoirs of multidrug resistance genes in the Eastern Cape Province environment.

    A questionnaire of 15 questions was completed by four categories of respondents with the aim of establishing the experience and opinions of these groups on the constraints including animal health problems for communal, small-scale sheep and goat farming in the Eastern Cape province of South Africa. The questionnaires were completed independently and categories were representative of the areas investigated. Analysis of responses was done by means, ranges, votes and clusters of responses. Comparisons between the responses of the four categories were made to identify similarities or contrasts. The results revealed that of non-veterinary concerns, stock theft was the major problem for these farms. Nutrition was a further major constraint. A third area of significant concern was the provision or availability of facilities like fences, water troughs, dips and sheds. Lack of marketing and business skills were also seen as important deficiencies to be rectified so as to promote profitable farming. Of the most important veterinary problems identified, the provision, availability, cost and care of drugs and vaccines were seen as major stumbling blocks to effective disease control, as well as lack of access to veterinary services. The most important diseases that constrain small-ruminant livestock farming in the farming systems investigated were sheep scab and other ectoparasites, heart water, enterotoxaemia, internal parasites and bluetongue. A lack of knowledge in key areas of small-stock farming was revealed and should be rectified by an effective training and support programme to improve the contribution of small-ruminant farming to livelihoods in these communities.

    2015-04-01

    Full Text Available Background: Antimicrobial resistance in microorganisms are on the increase worldwide and are responsible for substantial cases of therapeutic failures. Resistance of species of Enterococcus to antibiotics is linked to their ability to acquire and disseminate antimicrobial resistance determinants in nature, and wastewater treatment plants (WWTPs are considered to be one of the main reservoirs of such antibiotic resistant bacteria. We therefore determined the antimicrobial resistance and virulence profiles of some common Enterococcus spp that are known to be associated with human infections that were recovered from hospital wastewater and final effluent of the receiving wastewater treatment plant in Alice, Eastern Cape. Methods: Wastewater samples were simultaneously collected from two sites (Victoria hospital and final effluents of a municipal WWTP in Alice at about one to two weeks interval during the months of July and August 2014. Samples were screened for the isolation of enterococci using standard microbiological methods. The isolates were profiled molecularly after targeted generic identification and speciation for the presence of virulence and antibiotic resistance genes. Results: Out of 66 presumptive isolates, 62 were confirmed to belong to the Enterococcus genusof which 30 were identified to be E. faecalis and 15 E. durans. The remaining isolates were not identified by the primers used in the screening procedure. Out of the six virulence genes that were targeted only three of them; ace, efaA, and gelE were detected. There was a very high phenotypic multiple resistance among the isolates and these were confirmed by genetic analyses. Conclusions: Analyses of the results obtained indicated that hospital wastewater may be one of the sources of antibiotic resistant bacteria to the receiving WWTP. Also, findings revealed that the final effluent discharged into the environment was contaminated with multi-resistant enterococci species thus

    Full Text Available Background: The Nutrition Therapeutic Programme (NTP involves the provision of food supplements at primary health clinics (PHCs to correct nutritional deficiencies in vulnerable groups. Although previous studies have identified problems with implementing the programme at PHCs, assessments of its efficiency have been scarce.Objective: To evaluate implementation of the NTP at PHCs that provide antiretroviral therapy.Methods: A cross-sectional, descriptive study was conducted at 17 PHCs located within 3 districts of Western Cape Province. Two target groups were chosen: 32 staff members working at the sites and 21 women of child-bearing age enrolled in the NTP. Questionnaires were used to obtain data.Results: Only 2 women (10% lived in food-secure households; the rest were either at risk of hunger (29% or classified as hungry (61%. Most of the women knew they had to take the supplements to improve their nutritional status, but the majority only recalled receiving basic nutritional advice, and the information was mainly given verbally. Ten of the women had shared their supplements with others, mostly with their children. The study identified lack of clearly defined NTP responsibilities at the PHCs, causing confusion amongst the staff. Although many staff members expressed problems with the NTP, only 38% of them reported having routine evaluations regarding the programme.Conclusion: Several aspects compromised the effectiveness of the NTP, including socio- economic factors leading to clients’ non-compliance. The strategic organisation and implementation of the NTP varied between different PHCs offering antiretroviral therapy, and staff experienced difficulties with the logistics of the programme.

    Full Text Available Abstract Background This study evaluated the primary school environment in terms of being conducive to good nutrition practices, sufficient physical activity and prevention of nicotine use, with the view of planning a school-based health intervention. Methods A sample of 100 urban and rural disadvantaged schools was randomly selected from two education districts of the Western Cape Education Department, South Africa. A situation analysis, which comprised an interview with the school principal and completion of an observation schedule of the school environment, was done at all schools. Results Schools, on average, had 560 learners and 16 educators. Principals perceived the top health priorities for learners to be an unhealthy diet (50% and to far lesser degree, lack of physical activity (24% and underweight (16%. They cited lack of physical activity (33% and non-communicable diseases (NCDs; 24% as the main health priorities for educators, while substance abuse (66% and tobacco use (31% were prioritised for parents. Main barriers to health promotion programmes included lack of financial resources and too little time in the time table. The most common items sold at the school tuck shops were crisps (100%, and then sweets (96%, while vendors mainly sold sweets (92%, crisps (89%, and ice lollies (38%. Very few schools (8% had policies governing the type of food items sold at school. Twenty-six of the 100 schools that were visited had vegetable gardens. All schools reported having physical activity and physical education in their time tables, however, not all of them offered this activity outside the class room. Extramural sport offered at schools mainly included athletics, netball, and rugby, with cricket and soccer being offered less frequently. Conclusion The formative findings of this study contribute to the knowledge of key environmental and policy determinants that may play a role in the health behaviour of learners, their parents and their

    Full Text Available Abstract Background To evaluate the antibiogram and antibiotic resistance genes of some Vibrio strains isolated from wastewater final effluents in a rural community of South Africa. V. vulnificus (18, V. metschnikovii (3, V. fluvialis (19 and V. parahaemolyticus (12 strains were isolated from final effluents of a wastewater treatment plant (WWTP located in a rural community of South Africa. The disk diffusion method was used for the characterization of the antibiogram of the isolates. Polymerase chain reaction (PCR was employed to evaluate the presence of established antibiotic resistance genes using specific primer sets. Results The Vibrio strains showed the typical multidrug-resistance phenotype of an SXT element. They were resistant to sulfamethoxazole (Sul, trimethoprim (Tmp, cotrimoxazole (Cot, chloramphenicol (Chl, streptomycin (Str, ampicillin (Amp, tetracycline (Tet nalidixic acid (Nal, and gentamicin (Gen. The antibiotic resistance genes detected includes dfr18 and dfrA1 for trimethoprim; floR, tetA, strB, sul2 for chloramphenicol, tetracycline, streptomycin and sulfamethoxazole respectively. Some of these genes were only recently described from clinical isolates, demonstrating genetic exchange between clinical and environmental Vibrio species. Conclusions These results demonstrate that final effluents from wastewater treatment plants are potential reservoirs of various antibiotics resistance genes. Moreover, detection of resistance genes in Vibrio strains obtained from the wastewater final effluents suggests that these resistance determinants might be further disseminated in habitats downstream of the sewage plant, thus constituting a serious health risk to the communities reliant on the receiving waterbodies.

    This study assessed the microbiological quality of various ready-to-eat foods sold in Alice, South Africa. Microbiological analysis was conducted on 252 samples which included vegetables, potatoes, rice, pies, beef and chicken stew. The isolates were identified using biochemical tests and the API 20E, API 20NE and API Listeria kits; results were analyzed using the one-way-ANOVA test. Bacterial growth was present in all the food types tested; high levels of total aerobic count were observed in vegetables, 6.8 ± 0.07 followed by rice, 6.7 ± 1.7 while pies had the lowest count (2.58 ± 0.24). Organisms isolated included: Listeria spp. (22%), Enterobacter spp. (18%), Aeromonas hydrophila (12%), Klebsiella oxytoca (8%), Proteus mirabilis (6.3%), Staphylococcus aureus (3.2%) and Pseudomonas luteola (2.4%). Interestingly, Salmonella spp. and Escherichia coli were not isolated in any of the samples. There was a statistically significant difference (p < 0.05) in the prevalence of foodborne pathogens from hygienic and unhygienic cafeterias. The results indicated that most of the ready-to-eat food samples examined in this study did not meet bacteriological quality standards, therefore posing potential risks to consumers. This should draw the attention of the relevant authorities to ensure that hygienic standards are improved to curtain foodborne infections. PMID:23066386

    Full Text Available Blowfly strike and the methods used to combat blowfly strike were recorded on 33 properties in the Rûens area of South Africa during 2003/2004. Data were recorded on Merino and Dohne Merino hoggets (n = 4951 with at least 3 months’ wool growth. The following data were captured: presence or absence of strike, site of the strike (body or breech, presence or absence of dermatophilosis as well as subjective scores for wool quality and wool colour. Control measures recorded include: chemical treatment (preventative and spot treatment, crutching, mulesing and the use of the Lucitrap® system. Blowfly strike was not significantly influenced by gender or breed. Hoggets suffering from dermatophilosis were more likely to be struck, compared with contemporaries not suffering from the skin disorder (0.057 vs 0.027; P < 0.05. Merino hoggets generally had higher scores than their Dohne Merino contemporaries for wool quality (32.6 vs 27.4; P<0.05 and wool colour (29.0 vs 27.2; P<0.05. There was an indication that the Lucitrap® system may have reduced flystrike, but the effect was not statistically significant (P = 0.19 for overall strikes and P = 0.12 for body strike. The Mules operation benefited overall flystrike (0.013 vs 0.110; P < 0.05; mainly through an effect on breech strike (0.010 vs 0.109; P < 0.05. The proportion of fly strikes increased with wool length, and declined with an increase in farm size in wool colour score. None of the ethically acceptable control measures assessed could substantially reduce blowfly strike on their own, and an integrated pest management programme was proposed.

    Captive and wild psittacines are vulnerable to the highly contagious psittacine beak and feather disease. The causative agent, beak and feather disease virus (BFDV), was recently detected in the largest remaining population of endangered Cape parrots (Poicepahlus robustus), which are endemic to South Africa. Full-length genomes were isolated and sequenced from 26 blood samples collected from wild and captive Cape parrots to determine possible origins of infection. All sequences had characteristic BFDV sequence motifs and were similar in length to those described in the literature. However, BFDV coat protein (CP) sequences from this study did not contain a previously identified bipartite nuclear localisation signal (NLS) within residues 39-56, which indicates that an alternate NLS is involved in shuttling the CP into the nucleus. Sequences from the wild population shared a high degree of similarity, irrespective of year or location, suggesting that the disease outbreak occurred close to the time when the samples were collected. Phylogenetic analysis of full-length genomes showed that the captive Cape parrot sequences cluster with those isolated from captive-bred budgerigars in KwaZulu-Natal Province, South Africa. Exposure to captive-bred Cape parrots from a breeding facility in KwaZulu-Natal is suggested as a possible source for the virus infection. Phylogenetic analysis of BFDV isolates from wild and captive Cape parrots indicated two separate infection events in different populations, which highlights the potential risk of introducing new strains of the virus into the wild population. The present study represents the first systematic investigation of BFDV virus diversity in the southern-most population of Cape parrots. PMID:25209153

    Full Text Available This study describes alcohol consumption in five Western Cape Province communities. Cross-sectional data from a community household sample (n = 591 describe the alcohol use patterns of adult males and females, and farm workers vs. others. Data reveal that men were more likely to be current drinkers than women, 75.1% vs. 65.8% (p = 0.033; farm laborers were more likely to be current drinkers than individuals in other occupations 83.1% vs. 66.8% (p = 0.004. Group, binge drinking on weekends was the norm; men were more likely to be binge drinkers in the past week than women 59.8% vs. 48.8% (p = 0.086; farm workers were more likely to binge than others 75.0% vs. 47.5% (p < 0.001. The legacy of “Dop” contributes to current risky drinking behaviors. Farm owners or managers were interviewed on 11 farms, they described working conditions on their farms and how the legacy of “Dop” is reflected in the current use of alcohol by their workers. “Dop” was given to farm workers in the past on six of the 11 farms, but was discontinued for different reasons. There is zero tolerance for coming to work intoxicated; farm owners encourage responsible use of alcohol and assist farm workers in getting help for alcohol problems when necessary. The farm owners report some positive initiatives, were ahead of the movement to provide meaningful wages, and provide other important amenities. Further research is needed to assess whether progressive practices on some farms will reduce harmful alcohol use.

    Full Text Available An analysis of the fynbos shrublands and forests of the Boosmansbos Wilderness Area, southern Langeberg, Cape Province, South Africa, is presented. Data were collected at 119 sites in mature fynbos vegetation (>10 years old and at five sites in patches of Afromontane Forest. Emphasis was placed on the fynbos shrublands and sample sites were subjectively located along a transect from south to north across the Langeberg range in the study area. This south to north orientation follows a complex gradient of changes in aspect, slope, geology, soil form and climate. Data were initially analysed using TWINSPAN and the resulting classification refined using Braun-Blanquet procedures. One forest subassociation and 12 fynbos communities were identified and described. A proposed hierarchical classification of the fynbos communities is presented.

    Full Text Available Riparian plant communities fulfil many functions, including the provision of corridors linking protected areas and other zones of high conservation value. These habitats across much of South Africa’s Cape Floristic Region, especially in the lowlands, have been heavily impacted and degraded by human activities. There is increasing interest in the restoration of degraded riparian zones and the ecosystem services they provide to enhance the conservation value of landscapes. Previous studies of riparian vegetation in the Cape Floristic Region focused on pristine headwater systems, and little is known about human-impacted communities that make up most of the riparian vegetation in downstream areas. More information is needed on the composition of these plant communities to establish a baseline for management intervention. The riparian zone of the Eerste River in South Africa’s Western Cape province provides a good opportunity to study the features of riparian vegetation along the entire gradient, from pristine vegetation in a protected area through different levels of human-mediated degradation. Riparian vegetation was surveyed in 150 plots along the entire length of the Eerste River (ca. 40 km. Data were analysed using the vegetation classification and analysis software package JUICE. Final groupings were plotted onto a two-dimensional detrended correspondence analysis plane to check the position of the communities in the reduced multidimensional space. Ten distinct plant communities were identified, including several novel communities dominated by alien plant species. Descriptions of each plant community are presented. Diagnostic, constant and dominant species are listed and the major structural and ecological characteristics of each community are described.Conservation implications: Major changes to hydrological and soil properties, nutrient dynamics and disturbance regimes and plant species composition along sections of the riparian zone mean

    Campbell, Stuart A.; Götz, Annette E.; Montenari, Michael

    2016-04-01

    A study on world shale reserves conducted by the Energy Information Agency (EIA) in 2013 concluded that there could be as much as 390 Tcf recoverable reserves of shale gas in the southern and south-western parts of the Karoo Basin. This would make it the 8th-largest shale gas resource in the world. However, the true extent and commercial viability is still unknown, due to the lack of exploration drilling and modern 3D seismic. Within the framework of the Karoo Research Initiative (KARIN), two deep boreholes were drilled in the Eastern and Western Cape provinces of South Africa. Here we report on new core material from borehole KZF-1 (Western Cape) which intersected the Permian black shales of the Ecca Group, the Whitehill Formation being the main target formation for future shale gas production. To determine the original source potential for shale gas we investigated the sedimentary environments in which the potential source rocks formed, addressing the research question of how much sedimentary organic matter the shales contained when they originally formed. Palynofacies indicates marginal marine conditions of a stratified basin setting with low marine phytoplankton percentages (acritarchs, prasinophytes), good AOM preservation, high terrestrial input, and a high spores:bisaccates ratio (kerogen type III). Stratigraphically, a deepening-upward trend is observed. Laterally, the basin configuration seems to be much more complex than previously assumed. Furthermore, palynological data confirms the correlation of marine black shales of the Prince Albert and Whitehill formations in the southern and south-western parts of the Karoo Basin with the terrestrial coals of the Vryheid Formation in the north-eastern part of the basin. TOC values (1-6%) classify the Karoo black shales as promising shale gas resources, especially with regard to the high thermal maturity (Ro >3). The recently drilled deep boreholes in the southern and south-western Karoo Basin, the first since the

    Full Text Available Three new annual species of Diascia Link & Otto are described from the Western Cape Province of South Africa. D. collina is characterized by greyish magenta flowers with two divergent yellow sacs containing oil-secreting trichomes. It is restricted to granite outcrops in the vicinity of Saldanha Bay, from the West Coast National Park and Langebaan north to Vredenburg. D. pusilla is closely related to D. collina. but differs from that species in having smaller flowers with shorter, ± parallel sacs, and posticous filaments that lack a protuberance where they bend sharply backwards towards the upper lip. It occurs in grey to whitish sands usually near seasonally moist or wet areas. It has not been found more than 35 km from the coast and ranges from Modderrivier, south o f Darling, north to Lambert’s Bay. D. appendiculata is related to D. diffusa (Thunb. Benth. and is characterized by having small, mainly reddish lilac to greyish magenta flowers, two shallow depressions in the corolla tube at the base of the upper lip, and posticous filaments with sterile appendages. It is known from only six localities in the general vicinity of Citrusdal and occurs in fynbos vegetation on lower mountain slopes or flats, in loose alluvial sands derived from Table Mountain Sandstone.

    2009-12-15

    Eskom and the University of Fort Hare are engaged in a biomass gasification project using the System Johansson Biomass gasifier (SJBG). The SJBG installed at Melani village in the Eastern Cape province of South Africa is used to assess the viability and affordability of biomass gasification in South Africa. A community needs assessment study was undertaken at the village before the installation of the plant. The study revealed the need for low-cost electricity for small businesses including growing of crops, chicken broilers, manufacturing of windows and door frames, sewing of clothing, bakery etc. It was also found that the community had a problem with the socio-environmental aspects of burning biomass waste from the sawmill furnace as a means of waste management. The SJBG uses the excess biomass materials (waste) to generate low-cost electricity to drive community economic development initiatives. A study on the properties and suitability of the biomass materials resulting from sawmill operation and their suitability for gasification using the SJBG was undertaken. The study established that the biomass materials meet the requirements for the SJBG. A 300 Nm{sup 3}/h SJBG was then manufactured and installed at the village. (author)

    The South-East Karst Province of South Australia is an extensive area of low relief with dolines, cenotes, uvalas, and a variety of cave types developed in the soft, porous, flat-lying Tertiary Gambier Limestone and also as syngenetic karst in the overlying calcarenite dunes of the Pleistocene Bridgewater Formation. The most spectacular surface karst features are the large collapse dolines, especially those that extend below the water table to form cenotes. Shallow swampy hollows occur in superficial Quaternary sediments. These are an enigmatic feature of the Bool Region, where all gradations appear to occur between definite karst dolines and nonkarstic hollows. Some depressions may be polygenetic—involving a combination of: (1) primary depositional hollows on coastal flats or in dune fields, (2) deflation, and (3) karst solution and subsidence. There are extensive underwater cave systems in the southern part of the province, and the bulk of the cave development there may well lie below the present water table, although these systems would have been at least partly drained during the lower sea levels of the last glacial period. Systematic variations within the province reflect differences in the parent rock types, the extent and nature of the cover and, most importantly, the hydrology—in particular the depth to the water table and its gradient.

    Full Text Available Background: South Africa has a 32-year history of training ophthalmic nurse practitioners (ONPs. The role and required skills and competencies of ONPs are not well documented in the international literature and are also absent from South African publications, including South African Nursing Council publications. Aim: This study aims to inform curriculum development and human resource planning by reporting on the clinical skills expected of ONPs by members of multidisciplinary ophthalmology teams. Method: A limited survey was undertaken in the ophthalmology wards and outpatient departments of three tertiary level hospitals in the Western Cape Province. A researcher-designed structured self-completion questionnaire was distributed to 30 ophthalmology practitioners: doctors, nurses and technicians. Respondents were asked to indicate the expected clinical skills of ONPs. Findings: All questionnaires were completed. All respondents favoured ONPs taking histories and performing emergency eye irrigations. There was less support for more complex procedures, such as B-scans. One-third of respondents did not expect ONPs to have skills in eight key areas, including examination of the anterior chamber angle for glaucoma. No statistically significant differences were found between responses of doctors and nurses, with one exception: more nurses (15/18 than doctors (4/10 had confidence in the ONP undertaking basic eye examinations for ocular motility (Fisher‘s exact test, P = 0 .035. Conclusion: In the study settings, ONPs are not using their specialist skills to the full. Not all practitioners were receptive to ONPs using the skills that they had acquired during their postgraduate diploma, threatening the educational effectiveness of this initiative.

    Full Text Available Purpose: The purpose of the article is to explore the supplier relationship practices of travel agencies in the Western Cape province. The article wants to establish the current supplier relationship practices of travel agencies in the province and to identify limitations in supplier market relationships which might exist in the industry. Problem investigated: Relationships are the basis on which trade in the travel industry is built (George, 2006:224. The establishment and management of these relationships must be to the advantage of all parties in the relationship (Swart, 2003:120. Townes (2007 indicated that the current level of relationships that exists between travel agencies and their suppliers, especially the South African Airways (SAA, the Protea and Southern Sun hotel groups and motor vehicle rental companies such as AVIS is fragmented and negatively impairs on the ability of travel agents to deliver a quality service to their customers. To improve their overall level of service delivery to both corporate and leisure customers, it is important for travel agencies to know and understand the current level of their relationships with suppliers. It is against this background that the research was undertaken. Methodology: The target population for this study was 118 travel agencies of which 61 managers and/or owners participated through personal interviews in the completion of questionnaires. Data analysis was done by calculating averages and standard deviations, Explorative Factor Analysis (EFA, Cronbach Alpha-values and practical significance by means of effect sizes. Findings: The owners and managers of travel agencies are of the opinion that the strengthening of their existing relationships with suppliers must be prioritised. More emphasis should be placed on the strengthening of existing communication channels between travel agencies and their suppliers to secure the faster resolution of queries and complaints and to enhance the sharing

    Full Text Available The Pondoland region of the Eastern Cape province, South Africa is very poorly studied with regard to invertebrate diversity, particularly in the case of arachnids. Accordingly, and in view of proposed infrastructural and mining developments in this ecologically sensitive area of high plant endemism, baseline data are provided on spiders (Araneae of the vegetation layer (i.e. excluding the ground-dwelling fauna of the Mkambati Nature Reserve (MNR. Spiders were collected at 26 sites (six forest and 20 grassland sites in the MNR over an eight-day period, using sweep sampling and active searching of flowers in grassland and tree beating in forests, as part of a broader biodiversity survey. Additional specimens were collected with Malaise and pan traps. A total of 1275 specimens were sampled, representing 132 species (6.6% of the total number recorded in South Africa in 103 genera and 29 families. Theridiidae and Araneidae were the most diverse spider families in the reserve, represented by 22 species each (16.7% of the total, followed by Thomisidae with 19 species (14.4% and Salticidae with 18 species (13.6%. Grassland and forest had distinct spider faunas, with only 24.2% of species being recorded from both biomes. The average number of species sampled per site in grassland and forest was 26 species for both habitats, although values for the two biomes are not directly comparable because different sampling methods were used. All 132 species are new records for the reserve, of which 20 were new records for the Eastern Cape and at least eight spider species may be new to science. The spider diversity captured despite temporal and methodological limits indicates that many additional species are likely to occur in the reserve. Conservation implications: If the MNR is not adequately conserved at least five new species, which may be confined to the area, would be at high risk of extinction and 15 other species endemic to the Pondoland and Kwa

    Full Text Available Abstract Background Symptom management for persons living with HIV (PLHIV or AIDS is an important part of care management. Limited information about symptom prevalence exists about HIV infected persons in South Africa, in particular in the context of antiretroviral treatment (ART. The aim of this study was to assess HIV symptoms and demographic, social and disease variables of people living with HIV in South Africa. Methods In 2007 607 PLHIV, sampled by all districts in the Eastern Cape Province and recruited through convenience sampling, were interviewed by PLHIV at health facilities, key informants in the community and support groups. Results Two-thirds of the PLHIV (66% classified themselves with being given an AIDS (advanced stage of HIV diagnosis, 48% were currently on ART, 35% were currently on a disability grant for HIV/AIDS and for 13% the disability grant had been stopped. Participants reported that on the day of the interview, they were experiencing an average of 26.1 symptoms out of a possible 64. In a regression model with demographic and social variables, higher HIV symptom levels were associated with lower educational levels, higher age, urban residence and not on a disability grant, lack of enough food and having a health insurance, and in a regression model with demographic, social and disease variables only being on ART, lack of enough food and having a health insurance were associated with HIV symptoms. Conclusion Symptom assessment provides information that may be valuable in evaluating AIDS treatment regimens and defining strategies to improve quality of life. Because of the high levels of symptoms reported, the results imply an urgent need for effective health care, home- and community-based as well as self-care symptom management to help patients and their families manage and control AIDS symptoms.

    Full Text Available Canine rabies is enzootic throughout Sub-Saharan Africa, including the Republic of South Africa. Historically, in South Africa the coastal provinces of KwaZulu-Natal and Eastern Cape were most affected. Alarmingly, outbreaks of canine rabies have been increasingly reported in the past decade from sites where it has previously been under control. From January 2010 to December 2011, 53 animal rabies cases were confirmed; these were mostly in domestic dogs from southern Johannesburg, which was previously considered to be rabies free. In addition, one case was confirmed in a 26-month old girl who had been scratched by a pet puppy during this period. The introduction of rabies into Gauteng Province was investigated through genetic analysis of rabies positive samples confirmed during the outbreak period. In addition, the nucleotide sequences of incidental cases reported in the province for the past ten years were also included in the analysis. It was found that the recent canine rabies outbreak in the Gauteng Province came from the introduction of the rabies virus from KwaZulu-Natal, with subsequent local spread in the susceptible domestic dog population of southern Johannesburg. The vulnerability of the province was also highlighted through multiple, dead-end introductions in the past ten years. This is the first report of a rabies outbreak in the greater Johannesburg area with evidence of local transmission in the domestic dog population.

  12. Towards measuring the transaction costs of co-management in Mkambati Nature Reserve, Eastern Cape, South Africa.

    During the last three decades, there has been an increased pursuit of participatory approaches to managing natural resources. In South Africa, this has been evident in the management of protected areas. In particular, land claims, which affect much of the conservation estate in South Africa, frequently result in co-management of protected areas by claimant communities and conservation agencies. This is occurring against a backdrop of declining state subsidies and growing expectations that South African conservation agencies will finance themselves while simultaneously stimulating local economic opportunities. In this context, it is important for co-management partners to understand and monitor the cost-effectiveness of management processes in achieving both the socio-economic and ecological targets of conservation management. Transaction costs are useful in gauging the cost-effectiveness of policies and institutions; however there is little methodological guidance for measuring transaction costs empirically. This study develops and tests a transaction costs model for a co-managed nature reserve in the Eastern Cape province of South Africa. Transaction costs were quantified by taking into account the total time spent in meetings annually, the daily opportunity cost of participants' time and the travel costs associated with attending such meetings. A key limitation in the development of this model was a lack of record keeping by the conservation agency. The model developed in this study offers a practical means for co-management partners in similar contexts to monitor how transaction costs change over time. PMID:24001677

  13. Differences in antiretroviral scale up in three South African provinces: the role of implementation management

    2010-07-01

    Full Text Available Abstract Background South Africa’s antiretroviral programme is governed by defined national plans, establishing treatment targets and providing funding through ring-fenced conditional grants. However, in terms of the country’s quasi-federal constitution, provincial governments bear the main responsibility for provision of health care, and have a certain amount of autonomy and therefore choice in the way their HIV/AIDS programmes are implemented. Methods The paper is a comparative case study of the early management of ART scale up in three South African provincial governments – Western Cape, Gauteng and Free State – focusing on both operational and strategic dimensions. Drawing on surveys of models of ART care and analyses of the policy process conducted in the three provinces between 2005 and 2007, as well as a considerable body of grey and indexed literature on ART scale up in South Africa, it draws links between implementation processes and variations in provincial ART coverage (low, medium and high achieved in the three provinces. Results While they adopted similar chronic disease care approaches, the provinces differed with respect to political and managerial leadership of the programme, programme design, the balance between central standardisation and local flexibility, the effectiveness of monitoring and evaluation systems, and the nature and extent of external support and programme partnerships. Conclusions This case study points to the importance of sub-national programme processes and the influence of factors other than financing or human resource capacity, in understanding intervention scale up.

    Full Text Available Models for estimating monthly average daily global solar radiation were developed for South African provinces. These models, in addition to the traditional sunshine hours used in existing models incorporates ambient temperature, relative humidity and wind speed as variable parameters for predicting global solar radiation, making it different from most of the existing models that use only sunshine hours as variable. Meteorological data obtained for nine locations in South Africa were employed in the model formulation. The accuracy of the models were verified by comparing estimated values with measured values in terms of the following statistical error tests: mean bias error (MBE, mean absolute bias error (MABE, mean absolute percentage error (MAPE, root mean square error (RMSE, and the regression coefficient (R2.The values of R2 for the formulated models are between the ranges of 90% - 99%. It was also observed that for an accurate estimation of global solar radiation in Eastern Cape Province, all weather elements are needed. This implies that the models give an excellent prediction for global solar radiation for their corresponding locations. Also, different errors calculated for the formulated models are close to zero especially MAPE. The result shows that the formulated models are good enough to be used to predict monthly average daily radiation for South Africa and also, the inclusion of some other elements in some of the models improved the accuracy of the predictions made by the models.

    Full Text Available Since the beginning of the new millennium, a plethora of works has been published on the making of the ‘creative city’ and the urban impact of the creative economy. So far, however, limited recognition has been given to how the development of cultural industries and the creative economy as a whole influences urban transformation in the rapidly urbanising Global South, especially in Africa. In Cape Town, a steadily growing number of creative industries and ‘culturepreneurs’ (Lange 2005 are carving out new spaces from the city’s highly contested urban setting. Over the past five years, the mixed-use, inner-city fringe area of Woodstock has seen the incessant arrival of creatives from various sectors. Travelling alongside is a property sector geared towards catering specifically for the creative industries’ spatial demands by turning old industrial structures – the remains of Woodstock’s former capacity as national hub for clothing, food processing and other light manufacturing – into creative centres hosting international film studios, leading galleries and designer ‘theatre retail spaces’. After setting the stage through a comprehensive introduction to the rise of the creative economy in South Africa and Cape Town, this article tunes into the current local development of Woodstock, based on extensive field research in the area. It traces ways and forms of conflict but also new social interfaces between the new creative tenants and the old established community, on the one hand pointing to problematic issues like lingering gentrification, sociospatial polarisation and lopsided cultural representation while also trying to flesh out some of the opportunities for finding the right frequency of engagement between creative industries and spaces of vernacular creativity within Cape Town’s post-apartheid urban realm.

  9. Healthcare experiences of lesbian and bisexual women in Cape Town, South Africa.

    2015-01-01

    Understanding the health needs and experiences of South African lesbian and bisexual women is imperative for implementing effective and inclusive public health strategies. Such understanding, however, is limited due to the exclusion of these women from most existing research on healthcare access in the region. This paper bridges that gap by investigating the healthcare experiences of lesbian and bisexual women in Cape Town. Data were gathered from 22 interviews with self-identified lesbian and bisexual community members and university students in the Cape Town area. Interviews explored obstacles women face in accessing affirming services, different experiences with public and private healthcare, fear of stigma/discrimination, availability of relevant sexual health information and suggestions to improve existing programmes. Findings suggest that South African lesbians and bisexual women may have a range of both positive and negative experiences in public and private health services, that they use protective strategies when 'coming out' and that they find that sexual health information pertinent to them is largely unavailable. These discussions contribute to a more inclusive understanding of the experiences of lesbian and bisexual women accessing healthcare and other services and help to inform providers, thereby enabling them to deliver more meaningful care to lesbian, gay, bisexual and transgender persons in South Africa.

  10. Trends in commercial handline catches of Redfishes along the Southern Cape Coast, Republic of South Africa

    Directory of Open Access Journals (Sweden)

    R. J. M Crawford

    1982-11-01

    Full Text Available During the period 1898-1906 red romans Chrysoblephus laticeps dominated redfish landings at Strand and Hermanus, Republic of South Africa, ports subject to cool upwelling conditions. Red stumpnoses C. gibbiceps were the main species along the eastern Cape Peninsula and seventy-fours Polysteganus undulosus at most harbours east of Cape Agulhas. By the late 1970's romans were dominant between Kalk Bay and Arniston and also important contributors else-where, but seventy-fours were only recorded in any significant quantities from Port Alfred. Interpretation of these trends is complicated by a lumping of catches, but the possibility of an environmental change favouring romans (cooler water at the expense of seventy-fours (warmer water cannot be discounted. Other marine forms having a biology associated with cooler waters have also increased along the southern Cape coast in recent years. Redfish resources at Gans Bay and Struts Bay are not currently overexploited, but provide a valuable source of remuneration for local fishermen when preferred target species are absent. Limited data collected in the Tsitsikamma Coastal National Park indicate that dageraad C. cristiceps populations could deteriorate rapidly if subjected to high fishing pressure. The contribution of dageraads to combined redfish landings is currently highest in areas of low exploitation.

    Alicyclobacilli were isolated from orchard soil collected from an apple and pear farm in Elgin, Western Cape, South Africa. Morphological, biochemical and physiological characteristics of the isolates were used to presumptively classify them as belonging to the genus Alicyclobacillus. Strains were identified to species level by polymerase chain reaction (PCR) with genus-specific primers, and 16S ribosomal RNA (rRNA) gene sequencing. To our knowledge this is the first report on the isolation of Alicyclobacillus acidoterrestris and Alicyclobacillus acidocaldarius from orchard soil. The presence of these organisms in the soil suggests a possible source of contamination for the final fruit juice, concentrate or pulp. PMID:17938854

    Full Text Available Stroke is a leading cause of death and a major cause of disability globally. Individuals with physical disabilities, including thosewho have suffered a stroke are at risk of secondary complications due to the impact of their disability, which may be exacerbated by their lifestylechoices. The aim of the present study was to determine the health riskbehaviours and factors that influence these behaviours of stroke patients inthe Metropole Region of the Western Cape, South Africa. A cross – sectionalsurvey, utilizing a self-administered questionnaire on a convenient sampleof 417 stroke patients, was used to collect data. A sub-sample of 10 parti-cipants was purposively selected for in-depth, face-to-face interviews.Approximately forty percent (40.3% of the participants did not engage in physical exercise. While 30.2% smoked only9% abused alcohol. A significant association was found between age and smoking (p<0.002. Information gathered in the in-depth interviews revealed factors that influenced the behaviours of the participants. These factors includedlack of financial resources and lack of access to information. As participants were found to be at risk of secondarycomplications because of poor lifestyle choices, there is a clear need to implement health promotion programmes topromote well-ness enhancing behaviours in order to enhance the quality of health of patients who have suffered astroke in the Western Cape, South Africa.

    Full Text Available HIV/AIDS knowledge is an important component of HIV/AIDS risk prevention strategies that may influence engagement in high risk behavior. This paper examines HIV/AIDS prevention knowledge among a representative sample of 4,174 youth living in Cape Town, South Africa. Data come from the Cape Area Panel Study (CAPS, and include black, coloured, and white respondents ages 14-22. Using an open-ended question, respondents were asked to name ways people can protect themselves from HIV/AIDS infection. Nearly everyone could name at least one method of preventing HIV infection, and respondents named two methods on average. Condoms, abstinence, and limiting the number of sexual partners/having only one sexual partner were the most frequently named prevention methods. Multivariate analysis was used to analyze correlates of specific forms of HIV/AIDS prevention, as well as the total number of prevention methods named by each respondent. Having had sex, highest grade completed, and race were the most commonly significant correlates across models. Race interaction terms were also significant, suggesting that the significance of HIV/AIDS knowledge correlates varies across racial groups. Overall, the results suggest that more depth of knowledge about HIV/AIDS is needed among South African youth to ensure proper protection from the disease, and that HIV/AIDS education might be more successful if tailored to specific racial/ethnic groups.

    A retrospective study was undertaken to determine aetiological factors for 117 catastrophic neck injuries in rugby players admitted to the Spinal Cord Unit, Conradie Hospital, Cape Town, between 1963 and 1989. Nineteen of these players were known to be dead; the files of another 10 were missing. Questionnaires were sent to the remaining 88 players and 52 responded (59%). Their data were supplemented with information obtained from the medical records of the patients who did not respond. The annual number of admissions increased dramatically after 1976 with 83% of all injuries occurring after that date. A further increase since 1984 contrasts with a falling incidence of these injuries in Britain, Australia and New Zealand. Increased risk of injury was related to the following factors: 98% of injuries occurred in matches and 81% were incurred by adults; 69% of injuries occurred in age-group A team or senior first team players; and 57% of injuries occurred in the tackle situation and 39% in scrums, rucks and mauls. Hooker, centre and flyhalf were the playing positions at greatest risk. Injuries were more common in early season matches and again after the mid-season break. This study confirmed that spinal cord injuries occur under predictable circumstances and are therefore foreseeable and preventable. The high incidence of these injuries in the Cape Province is as unacceptable today as it was when first reported in 1977. PMID:1862445

    Full Text Available Background: A preceptor is a specialised tutor who provides practical training to students in the practice setting. They are frequently used to orientate nursing students to prepare them for their duties as professional nurses. In the Western Cape Province professional nurses attend a training programme to prepare them for the role of preceptor. After completion of the training it is unclear how the trained nurse preceptors perceive their preparation for the role. The perceptions of preceptors may influence their commitment to their role. Objective: The purpose of this study was to explore nurse preceptors’ perceptions of benefits, support and commitment to the preceptor role. A conceptual framework guided the study which replicated previous studies that explored nurse preceptors’ perceptions. Method: A quantitative approach utilising a descriptive correlational design was used in this study to address the research questions. A convenience sample was drawn from preceptors (n = 60 who had completed a preceptor training programme at the University of the Western Cape. Instrumentation for the study included the following scales: preceptors’ perceptions of benefits and rewards, preceptors’ perceptions of support, and commitment to the preceptor role. Data analysis was performed using SPSS 20.0. Results: The findings indicate that nurse preceptors were committed to their role. Conclusion: The findings of this study are supported by Kanter’s model of structural determinants of behaviour in organisations, since preceptors who see themselves as having access to opportunity and support are likely to be committed to their role.

    Full Text Available Background: The prevalence of HIV among antenatal clients in South Africa has remained at a very high rate of about 29% despite substantial decline in several sub-Saharan countries. There is a paucity of data on risk factors for incident HIV infection among antenatal mothers and women within the reproductive age bracket in local settings in the Eastern Cape, South Africa. Objective: To establish the risk factors for incident HIV infection among antenatal clients aged 18–49 years attending public antenatal clinics in rural Eastern Cape, South Africa. Design: This was an unmatched case–control study carried out in public health antenatal clinics of King Sabata District Municipality between January and March 2014. The cases comprised 100 clients with recent HIV infection; the controls were 200 HIV-negative antenatal clients. Socio-demographic, sexual, and behavioral data were collected using interviewer-administered questionnaires adapted from the standard DHS5 women's questionnaire. Multivariate logistic regression models were used to identify the independent risk factors for HIV infection. A p<0.05 was considered statistically significant. Results: The independent risk factors for incident HIV infection were economic dependence on the partner, having older male partners especially among women aged ≤20 years, and sex under the influence of alcohol. Conclusions: Therefore, effective prevention of HIV among antenatal mothers in KSDM must target the improvement of the economic status of women, thereby reducing economic dependence on their sexual partners; address the prevalent phenomenon of cross-generation sex among women aged <20 years; and regulate the brewing, marketing, and consumption of alcohol.

  20. A preliminary account of aerial plant biomass in fynbos communities of the Mediterranean-type climate zone of the Cape Province

    Directory of Open Access Journals (Sweden)

    F. J. Kruger

    1977-12-01

    Full Text Available Aerial plant biomass has been sampled by harvesting on several sites in fynbos communities of the south­western Cape Province. Biomass in stands of about two years old ranged from about 2 200 kg per ha to about 7 500 kg per ha. Mature stands comprised about 11 000 to 15 000 kg per ha in heaths and 15 000 to 26 000 kg per ha in sclerophyllous scrub. The data indicate a maximum annual growth rate of 1 000 to 4 000 kg per ha early in the development of a stand, but growth rates appear to decline rapidly as communities age. Young stands are dominated by hemicryptophytes, which comprise about 2 000 to  6  000 kg per ha, or about 60 to 75 per cent of the biomass in stands of about four years old. Shrubs become prominent later, but the hemicryptophytes persist. The data indicate that the biomass, growth rates and the shape of the growth curves of fynbos communities are on the whole similar to those of analogous vegetation in other zones of mediterranean type climate. However, there are important structural differences in that analogues of the northern hemisphere (garrigue, chaparral do not have a significant component of persistent hemicrytophytes. Although Australian heath communities do have this feature, the hemicryptophytes are not as prominent as in fynbos.

    Droughts remain a threat to grape yields in South Africa. Previous studies on the impacts of climate on grape yield in the country have focussed on the impact of rainfall and temperature separately; meanwhile, grape yields are affected by drought, which is a combination of rainfall and temperature influences. The present study investigates the impacts of drought on grape yields in the Western Cape (South Africa) at district and farm scales. The study used a new drought index that is based on simple water balance (Standardized Precipitation Evapotranspiration Index; hereafter, SPEI) to identify drought events and used a correlation analysis to identify the relationship between drought and grape yields. A crop simulation model (Agricultural Production Systems sIMulator, APSIM) was applied at the farm scale to investigate the role of irrigation in mitigating the impacts of drought on grape yield. The model gives a realistic simulation of grape yields. The Western Cape has experienced a series of severe droughts in the past few decades. The severe droughts occurred when a decrease in rainfall occurred simultaneously with an increase in temperature. El Niño Southern Oscillation (ENSO) appears to be an important driver of drought severity in the Western Cape, because most of the severe droughts occurred in El Niño years. At the district scale, the correlation between drought index and grape yield is weak ( r≈-0.5), but at the farm scale, it is strong ( r≈-0.9). This suggests that many farmers are able to mitigate the impacts of drought on grape yields through irrigation management. At the farm scale, where the impact of drought on grape yields is high, poor yield years coincide with moderate or severe drought periods. The APSIM simulation, which gives a realistic simulation of grape yields at the farm scale, suggests that grape yields become more sensitive to spring and summer droughts in the absence of irrigation. Results of this study may guide decision-making on

    Full Text Available Gaseous elemental mercury (GEM has been measured at the WMO Global Atmospheric Watch station at Cape Point, South Africa since September 1995. Two techniques were used: a low resolution manual technique till the end of 2004 and a high resolution automated technique since March 2007. The GEM measurements at Cape Point constitute only one component of the GAW monitoring program consisting of continuous measurements of CO, CH4, CO2, O3, N2O, and since March 1999 also of 222Rn. The seasonality and trend of GEM concentrations from the low resolution data was analyzed by Slemr et al. (2008 and the trend of the combined low and high resolution data until the end of 2009 by Slemr et al. (2011. In this paper we will present an updated analysis of the trend and seasonality of GEM data until the end of 2011 and compare these to measurements made at Troll, a Norwegian research station in Antarctica (Pfaffhuber et al., 2012.

    2015-11-01

    Full Text Available This paper seeks to understand the drivers and pathways of local livelihood change and the prospects for transformation towards a more sustainable future. Data are used from several studies, and a participatory social learning process, which formed part of a larger project in two sites in the Eastern Cape, South Africa. Secondary information from a wealth of related work is used to place our results within the historic context and more general trends in the country. Findings indicate that livelihoods in the rural Eastern Cape are on new trajectories. Agricultural production has declined markedly, at a time when the need for diversification of livelihoods and food security seems to be at a premium. This decline is driven by a suite of drivers that interact with, and are influenced by, other changes and stresses affecting local livelihoods. We distil out the factors, ranging from historical processes to national policies and local dynamics, that hamper peoples’ motivation and ability to respond to locally identified vulnerabilities and, which, when taken together, could drive households into a trap. We end by considering the transformations required to help local people evade traps and progress towards a more promising future in a context of increasing uncertainty.

    Antimicrobial resistance (AMR) is a global problem impeding the effective prevention/treatment of an ever-growing array of infections caused by pathogens; a huge challenge threatening the achievements of modern medicine. In this paper, we report the occurrence of multidrug resistance (MDR) in Escherichia coli strains isolated from discharged final effluents of two wastewater treatment facilities in the Eastern Cape Province of South Africa. Standard disk diffusion method was employed to determine the antibiotic susceptibility profile of 223 polymerase chain reaction (PCR)-confirmed E. coli isolates against 17 common antibiotics in human therapy and veterinary medicine. Seven virulence associated and fourteen antibiotic resistance genes were also evaluated by molecular methods. Molecular characterization revealed five pathotypes of E. coli in the following proportions: enterotoxigenic ETEC (1.4%), enteropathogenic EPEC (7.6%), enteroaggregative EAEC (7.6%), neonatal meningitis (NMEC) (14.8%), uropathogenic (41.7%), and others (26.9%). Isolates showed varying (1.7-70.6%) degrees of resistance to 15 of the test antibiotics. Multidrug resistance was exhibited by 32.7% of the isolates, with the commonest multiple antibiotic-resistant phenotype (MARP) being AP-T-CFX (12 isolates), while multiple antibiotic-resistant indices (MARI) estimated are 0.23 (Site 1) and 0.24 (Site 2). Associated antibiotic resistance genes detected in the isolates include: strA (88.2%), aadA (52.9%), cat I (15%), cmlA1 (4.6%), blaTEM (56.4%), tetA (30.4%), tetB (28.4%), tetC (42.2%), tetD (50%), tetK (11.8%), and tetM (68.6%). We conclude that municipal wastewater effluents are important reservoirs for the dissemination of potentially pathogenic E. coli (and possibly other pathogens) and antibiotic resistance genes in the aquatic milieu of the Eastern Cape and a risk to public health.

    Full Text Available The topic of this longitudinal study was reading promotion and its perceived benefits. The aim was to determine if reading promotion can lead to reader development and if reader development can lead to self-development, as is often claimed in the literature. A reading promotion project in the Northern Cape, South Africa, was monitored over a period of five years by using a selection of qualitative and quantitative data collection methods. The outcome of the study indicates that the reading promotion project was responsible for positive changes in the lives of the beneficiaries of the intervention. It especially points to the positive role access to appropriate reading material and prolonged and enthusiastic reading motivation can play in the lives of a developing community with little means.Keywords: reading; reading promotion; reader development; longitudinal

    Full Text Available Abstract Background Completion of substance abuse treatment is a proximal indicator of positive treatment outcomes. To design interventions to improve outcomes, it is therefore important to unpack the factors contributing to treatment completion. To date, substance abuse research has not examined the factors associated with treatment completion among poor, disadvantaged communities in developing countries. This study aimed to address this gap by exploring client-level factors associated with treatment completion among poor communities in South Africa. Methods Secondary data analysis was conducted on cross-sectional survey data collected from 434 persons residing in poor communities in Cape Town, South Africa who had accessed substance abuse treatment in 2006. Results Multiple regression analyses revealed that therapeutic alliance, treatment perceptions, abstinence-specific social support, and depression were significant partial predictors of treatment completion. Conclusions Findings suggest that treatment completion rates of individuals from poor South African communities can be enhanced by i improving perceptions of substance abuse treatment through introducing quality improvement initiatives into substance abuse services, ii strengthening clients' abstinence-oriented social networks and, iii strengthening the counselor-client therapeutic alliance.

    Full Text Available Background: In 2007, South Africa made family medicine a new speciality. Family physicians that have trained for this new speciality have been employed in the district health system since 2011. The aim of the present study was to explore the perceptions of district managers on the impact of family physicians on clinical processes, health system performance and health outcomes in the district health system (DHS of the Western Cape.Methods: Nine in-depth interviews were performed: seven with district managers and two with the chief directors of the metropolitan and rural DHS. Interviews were recorded, transcribed and analysed using the ATLAS-ti and the framework method.Results: There was a positive impact on clinical processes for HIV/AIDS, TB, trauma, noncommunicable chronic diseases, mental health, maternal and child health. Health system performance was positively impacted in terms of access, coordination, comprehensiveness and efficiency. An impact on health outcomes was anticipated. The impact was not uniform throughout the province due to different numbers of family physicians and different abilities to function optimally. There was also a perception that the positive impact attributed to family physicians was in the early stages of development. Unanticipated effects included concerns with their roles in management and training of students, as well as tensions with career medical officers.Conclusion: Early feedback from district managers suggests that where family physicians are employed and able to function optimally, they are making a significant impact on health system performance and the quality of clinical processes. In the longer term, this is likely to impact on health outcomes.

    Full Text Available Introduction: Adolescents having unprotected heterosexual intercourse are at risk of HIV infection and unwanted pregnancy. However, there is little evidence to indicate whether pregnancy in early adolescence increases the risk of subsequent HIV infection. In this paper, we tested the hypothesis that adolescent pregnancy (aged 15 or younger increases the risk of incident HIV infection in young South African women. Methods: We assessed 1099 HIV-negative women, aged 15–26 years, who were volunteer participants in a cluster-randomized, controlled HIV prevention trial in the predominantly rural Eastern Cape province of South Africa. All of these young women had at least one additional HIV test over two years of follow-up. Outcomes were HIV incidence rates per 100 person years and HIV incidence rate ratios (IRRs estimated by Poisson multivariate models. Three pregnancy categories were created for the Poisson model: early adolescent pregnancy (a first pregnancy at age 15 years or younger; later adolescent pregnancy (a first pregnancy at age 16 to 19 years; and women who did not report an adolescent pregnancy. Models were adjusted for study design, age, education, time since first sexual experience, socio-economic status, childhood trauma and herpes simplex virus type 2 infection. Results: HIV incidence rates were 6.0 per 100 person years over two years of follow-up. The adjusted IRR was 3.02 (95% CI 1.50–6.09 for a pregnancy occurring at age 15 or younger. Women with pregnancies occurring between 16 and 19 years of age did not have a higher incidence of HIV (IRR 1.08; 95% CI 0.64–1.84. Early adolescent pregnancies were associated with higher partner numbers and a greater age difference with partners. Conclusions: Early adolescent pregnancies increase the incidence of HIV among South African women. The higher risk is associated with sexual risk behaviours such as higher partner numbers and a greater age difference with partners rather than a

    Full Text Available Abstract Background Juvenile idiopathic arthritis (JIA is a disease that shows wide variations between differing populations. Since the recent international consensus on classification criteria, JIA has been widely described in many countries and population groups. There has been almost no data that describes JIA in an African, specifically Sub-Saharan African, setting. Therefore, the aim of this study is to describe disease characteristics, disease course, and functional disability in two tertiary centres in the Western Cape, South Africa and compare the findings to other JIA populations. Methods Eighty-six children were recruited during random clinic visits to rheumatology clinics at Tygerberg and Groote Schuur Hospital between April 2010 and April 2011. Children were diagnosed using International League of Associations for Rheumatology (ILAR 2001 classification criteria. Consent was obtained and medical records examined. The Childhood Health Assessment Questionnaires (CHAQ and visual analogue scales (VAS for pain and general well-being were completed and all children were examined by a researcher in conjunction with a paediatric rheumatologist. HIV status as well as tuberculosis disease and treatment were investigated. Results A total of 86 children were enrolled.

    Full Text Available In South Africa, ESCOM is the country’s main electricity supplier. Since 2008, Eskom has implemented load shedding on an ongoing basis as a result of insufficient electricity supply to meet the demands of all its customers. Owing to the fact that many organisations across South Africa are depended on electricity in order to function, previous research studies show that the wide-spread impact of load shedding has had an adverse on the sustainability of many of these organisations. Among these organisations are those based in the hospitality industry – imperative in relation to the stimulation of the national economy; directly related to tourism. Albeit the aforementioned, the sustainability of organisations in the hospitality industry is also heavily dependent on the productivity of their employees. For this research study the influence of load shedding on the productivity of the staff in the hospitality industry was investigated within one particular hotel (Hotel X based in Cape Town. Empirical research was deployed, making use of a mixed methods approach to obtain both quantitative data and qualitative data from respondents. Stemming from the findings it was found that load shedding did have an adverse influence on the productivity of staff in Hotel X, despite the fact that affordable measures were put in place to mitigate the disruptions caused by load shedding. Moreover, the latter dispensation was found to have an inadvertently adverse influence on the overall sustainability of Hotel X on the long run.

    Two heavy-mineral-bearing, very fine-grained sandstone beds occur in the upper part of the Weltevrede Formation of the Witteberg Group, 35 km east-north-east of Willowmore, Cape Province. The beds are located within a 10-m-thick stratigraphic interval approximately 100 m below the base of the Witpoort Formation. The beds are amalgamated and consist of up to 5 units, each representing deposition from a storm-surge ebb current. Nine samples taken from the upper bed and one from the lower were analysed for heavy-mineral content. In order of decreasing abundance the heavy-minerals are rutile, zircon, ilmenite, magnetite, monazite, staurolite and sphene. The zircon contains uranium and the monazite is thorium bearing. Simple linear regression analysis of three elements, three oxides, the heavy mineral fraction and the radiometric response indicate that the proportion of heavy minerals does not vary significantly between samples and that the radiometric response of the beds (determined with a portable gamma-ray scintillometer) is directly related to the heavy mineral content. The heavy minerals are concentrated in the upper 20 cm of each bed where deposition from suspension, during the final phase of storm activity, was predominant. Significant concentrations are limited to the upper bed

  15. Changing land- and seascape environments at Cape Sable, a coastal wetland complex in south florida

    Cape Sable, a large coastal wetland complex at the southern tip of the Florida peninsula (U.S.), is currently undergoing dramatic changes in land- and seascape in response to historical sea level rise. The rise in sea level is progressively inundating a low marl ridge that has separated interior freshwater marshes of the Everglades from marine waters, leading to rapid widening of both natural tidal creeks and constructed canals. The linear rate of widening (0.7 to 1.2 meter per year since 1922) reflects a system out of equilibrium, in which the channels are seeking to accommodate the volume of water in the tidal prism. Rising sea level has enlarged the tidal prism by expanding the intertidal zone into former low-lying uplands. Opening of the channels has resulted in the creation and erosive widening of secondary channels into adjacent wetlands, further enlarging the tidal prism and tendency to widening. In the vicinity of some tidal inlets, the shoreline has eroded over 310 meters (since 1922; an overall rate of 4.6 m/yr), although erosion occur in steps in response to hurricanes (category 5 hurricanes in 1935, 1960 and 1992). In addition to changing channel morphology and beach erosion, rising sea level has shifted the mangrove/ freshwater marsh ecotone boundary inland significantly. Continued sea-level rise will inundate the marl ridge and accelerate erosion and breakup of the Cape Sable beach shoreline. The coastal red mangrove wetland could possibly keep pace with accelerated sea level rise, but hurricane setbacks negate this effect in south Florida. Category 4 and 5 hurricanes devastate the red mangrove forests and set into motion a phase of root-peat substrate decay and subsidence which has caused stepwise loss of both coastal and interior forests during the past 70 years of rapidly rising sea level. Changes in the coastal wetland environments of south Florida, in which critical habitats are imminently threatened, are driven by nonlinear processes that

    Full Text Available Objective:Phenylalanine hydroxylase or its cofactor, tetrahydrobiopterin (BH4, deficiency causes accumulation of phenylalanine in body fluids and central nervous system. Considering the fact that hyperphenylalaninemia is a preventable cause of mental retardation in infants, the objective of this study was to determine the incidence of congenital hyperphenylalaninemia in Fars province, south of Iran.Methods:In a period of one year from November 2007 to November 2008 blood samples were withdrawn from all newborns born in Fars province for measurement of serum phenylalanine. The samples with a serum level of � 2 mg/dl were referred to pediatric endocrine clinic for confirmation and determination of the type of hyperphenylalaninemia by quantitive serum phenylalanine measurements by using High-Pressure liquid chromatography (HPLC method.Findings:Nine out of 76966 newborns had a serum phenylalanine level �2mg/dl, of which 8 cases were confirmed by HPLC. The incidence of the disease was 1:10000. The incidence of mild hyperphenylalaninemia and phenylketonuria (PKU among the patients was 62.5% and 37.5% respectively and the incidence of BH4 deficiency was 1/76966.Conclusion:These findings indicate a high incidence of hyperphenylalaninemia, in the newborns from Fars province. The high incidence makes a comprehensive screening program for management of the disease necessary.

    Extracted teeth collected from a Black African community living in the Gugulethu suburb of Cape Town, South Africa were studied by nuclear microscopy. Analysis by PIXE (with 3.0 MeV protons) of permanent extracted incisor and molar teeth from males and females of different ages showed a homogeneous elemental profile distribution for iron, zinc and strontium, irrespective of gender and/or age. Fluorine content as determined simultaneously from the 110 keV gamma-ray yield from proton bombardment had a similar mean value (females: 1.8% by mass and males: 1.6% by mass) for both genders. However, the mean content of strontium for females (97 μg g -1) was about 40% lower than that for males (69 μg g -1). In addition, a sub-group of children showed a smaller standard deviation on the distribution of zinc and fluorine. Previous results on the trace elemental concentration of the enamel of molar teeth, showed a depletion of up to 50% by mass for strontium after 20 h of exposure in acidic solution. Although the strontium level for the African female group fits this profile it is not certain what the demineralization observed was due too.

  3. Perceived vulnerability and HIV testing among youth in Cape Town, South Africa.

    2016-06-01

    The importance of perceived vulnerability to risk-reducing behaviors, including HIV testing, is fairly established, especially among youth in sub-Saharan Africa. Yet, the majority of studies that examined this important relationship used cross-sectional data that inherently assume that perceived vulnerability does not change. While these studies have been useful, the assumption of perceived vulnerability as time invariant is a major flaw and has largely limited the practical usefulness of this variable in AIDS prevention and programing. Using longitudinal data and applying random-effects logit models, this study makes a major contribution to scholarship by examining if changes in perceived vulnerability associate with a change to test for HIV among 857 young people in Cape Town, South Africa. Results show that female youth who changed their risk perceptions were more likely to also change to test for HIV, but the effects were completely attenuated after controlling for theoretically relevant variables. No significant relationships were observed for males. Also, females who were virgins at wave 2 but had sex between waves were significantly more likely to have changed to test for HIV. Of most importance was that sexual behavior eliminated the effects of change in risk perceptions suggesting that a change in perception may have occurred as a result of changes in sexual behavior. AIDS prevention programs must pay particular attention to helping youth become aware of their vulnerability to HIV risks, especially as these have implications for risk-reducing behaviors, especially for females who are burdened.

    Two Y-STR genotyping systems were evaluated for usefulness in forensic casework in the Cape Muslim population of South Africa. Samples were collected from 105 males, and genotyped for 17 loci amplified in two multiplexes. Allele and haplotype frequencies were determined for nine Y-STR loci used to define the minimal haplotype (DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, and the duplicated locus DYS385) amplified in one multiplex, as well as for eight widely used loci amplified in a second multiplex and consisting of DYS449, DYS481, DYS518, DYS557, DYS570, DYS607, DYS612 and DYS614. When analysing the samples for all the loci, 104 unique haplotypes were obtained, and the discrimination capacity was 0.990. When considering only the nine Y-STRs included in the minimal haplotype, 91 unique haplotypes were obtained, and the discrimination capacity was 0.866. In the case of the remaining eight Y-STR loci, values of 97 and 0.924 were obtained, respectively. PMID:19962930

  5. Host specificity and co-speciation in avian haemosporidia in the Western Cape, South Africa.

    Directory of Open Access Journals (Sweden)

    Sharon Okanga

    Full Text Available Host and pathogen ecology are often closely linked, with evolutionary processes often leading to the development of host specificity traits in some pathogens. Host specificity may range from 'generalist', where pathogens infect any available competent host; to 'specialist', where pathogens repeatedly infect specific host species or families. Avian malaria ecology in the region remains largely unexplored, despite the presence of vulnerable endemic avian species. We analysed the expression of host specificity in avian haemosporidia, by applying a previously developed host specificity index to lineages isolated from wetland passerines in the Western Cape, South Africa. Parasite lineages were isolated using PCR and identified when possible using matching lineages deposited in GenBank and in MalAvi. Parasitic clades were constructed from phylogenetic trees consisting of Plasmodium and Haemoproteus lineages. Isolated lineages matched some strains of Plasmodium relictum, P. elongatum, Haemoproteus sylvae and H. lanii. Plasmodium lineages infected a wide range of hosts from several avian families in a generalist pattern of infection. Plasmodium spp. also exhibited an infection trend according to host abundance rather than host species. By contrast, Haemoproteus lineages were typically restricted to one or two host species or families, and displayed higher host fidelity than Plasmodium spp. The findings confirm that a range of host specificity traits are exhibited by avian haemosporidia in the region. The traits show the potential to not only impact infection prevalence within specific host species, but also to affect patterns of infection at the community level.

    Full Text Available Abstract Background An estimated 2 million children are parentally bereaved by AIDS in South Africa. Little is known about mental health outcomes for this group. Methods This study aimed to investigate mental health outcomes for urban children living in deprived settlements in Cape Town. 30 orphaned children and 30 matched controls were compared using standardised questionnaires (SDQ on emotional and behavioural problems, peer and attention difficulties, and prosocial behaviour. The orphan group completed a modified version of a standardised questionnaire (IES-8, measuring Post-Traumatic Stress symptoms. Group differences were tested using t-tests and Pearson's chi-square. Results Both groups scored highly for peer problems, emotional problems and total scores. However, orphans were more likely to view themselves as having no good friends (p = .002, to have marked concentration difficulties (p = .03, and to report frequent somatic symptoms (p = .05, but were less likely to display anger through loss of temper (p = .03. Orphans were more likely to have constant nightmares (p = .01, and 73% scored above the cut-off for Post-Traumatic Stress Disorder. Conclusion Findings suggest important areas for larger-scale research for parentally-bereaved children.

    2013-04-01

    Full Text Available Introduction: A decreased frequency of unprotected sex during episodes of concurrent relationships may dramatically reduce the role of concurrency in accelerating the spread of HIV. Such a decrease could be the result of coital dilution – the reduction in per-partner coital frequency from additional partners – and/or increased condom use during concurrency. To study the effect of concurrency on the frequency of unprotected sex, we examined sexual behaviour data from three communities with high HIV prevalence around Cape Town, South Africa. Methods: We conducted a cross-sectional survey from June 2011 to February 2012 using audio computer-assisted self-interviewing to reconstruct one-year sexual histories, with a focus on coital frequency and condom use. Participants were randomly sampled from a previous TB and HIV prevalence survey. Mixed effects logistic and Poisson regression models were fitted to data from 527 sexually active adults reporting on 1210 relationship episodes to evaluate the effect of concurrency status on consistent condom use and coital frequency. Results: The median of the per-partner weekly average coital frequency was 2 (IQR: 1–3, and consistent condom use was reported for 36% of the relationship episodes. Neither per-partner coital frequency nor consistent condom use changed significantly during episodes of concurrency (aIRR=1.05; 95% confidence interval (CI: 0.99–1.24 and aOR=1.01; 95% CI: 0.38–2.68, respectively. Being male, coloured, having a tertiary education, and having a relationship between 2 weeks and 9 months were associated with higher coital frequencies. Being coloured, and having a relationship lasting for more than 9 months, was associated with inconsistent condom use. Conclusions: We found no evidence for coital dilution or for increased condom use during concurrent relationship episodes in three communities around Cape Town with high HIV prevalence. Given the low levels of self-reported consistent

    2016-07-01

    The link between interannual variability of seasonal rainfall over the Cape south coast of South Africa and different synoptic types as well as selected teleconnections is explored. Synoptic circulation over the region is classified into different synoptic types by employing a clustering technique, the self-organizing map (SOM), on daily circulation data for the 33-year period from 1979 to 2011. Daily rainfall data are used to investigate interannual variability of seasonal rainfall within the context of the identified synoptic types. The anomalous frequency of occurrence of the different synoptic types for wet and for dry seasons differs significantly within the SOM space, except for austral spring. The main rainfall-producing synoptic types are to a large extent consistent for wet and dry seasons. The main rainfall-producing synoptic types have a notable larger contribution to seasonal rainfall totals during wet seasons than during dry seasons, consistent with a higher frequency of occurrence of the main rainfall-producing synoptic types during wet seasons compared to dry seasons. Dry seasons are characterized by a smaller contribution to seasonal rainfall totals by all the different synoptic types, but with the largest negative anomalies associated with low frequencies of the main rainfall-producing synoptic types. The frequencies of occurrence of specific configurations of ridging high pressure systems, cut-off lows and tropical-temperate troughs associated with rainfall are positively linked to interannual variability of seasonal rainfall. It is also shown that the distribution of synoptic types within the SOM space is linked to the Southern Annular Mode and El Niño Southern Oscillation, implying some predictability of intraseasonal variability at the seasonal time scale.

  15. Continental tectonics and uranium province of South China

    International Nuclear Information System (INIS)

    The pre-Sinian metamorphic basement of South China consists of 4 blocks, namely the Jiangnan, the Wuyi, the Yunkai-South Sea and the Mintai which belong to the same lithospheric plate from late Proterozoic on. The plate is enriched in U and Th revealed by Pb-isotopic study, which plays an role of essential prerequisite for the formation of U province. The amalgamation of the 4 blocks and their final attachment to Yangtze craton were resulted from Proterozoic, Caledonian, Indonesia and Yangshanian orogenic events, driven by Moho-rheologic stratification so that uraniferous black rock sequences and U-hosting granites and volcanics in age from late Sinian to Jurassic were produced in the fore lands of corresponding major orogenic uplifts. The change of tectonic regime from compression-relaxed to lateral tension happened after significant crust's thickening and large-scale emplacement of granitic batholiths during late Triassic and early Jurassic though local compression occurred from middle Eocene to Oligocene. Most of U deposits were just formed in association with this para-cratonization process from late Jurassic to Eogene. South China GGT shows that there exist the thinning and the break-up of undercrustal lithosphere at the Datian and the Quanzhou and funnel-shaped seg at middle Hunan. The former two are considered to be the product of up-migration of hot mantle plume and the latter to be the place of down-migration of cold mantle plume

    Full Text Available Background: Traditional circumcision of males is common amongst many societies in sub-Saharan Africa. Circumcision amongst the Xhosa people of South Africa represents a rite of passage to manhood. Traditional male circumcision has an increased risk for complications that include sepsis, genitalmutilation, gangrenous penis, excessive bleeding, dehydration, renal failure and death. The aim of this study was to describe the complications of traditional circumcisions amongst Xhosa men as seen at St. Lucy’s Hospital in the Eastern Cape Province.Method: A cross-sectional descriptive quantitative study was conducted in 2008. Records of 105 malesadmitted to St. Lucy’s Hospital with complications following traditional circumcision were reviewed. Data collected included age, education level, race, reasons for circumcision, complications, the period of circumcision, duration of hospital stay and the outcomes. Descriptive data analysis was performed using statistical software SPSS 17.0.Results: The ages ranged from 15–35 years with 68 (64.8% between 15–19 years. 83 (79% had a secondarylevel of education, 16 (15.2% primary, 5 (4.8% tertiary and 1% had no education. 60 (57% werecircumcised as initiation to manhood, 21 (20.0% due to peer pressure, 20 (19.0% for cultural reasons, and 1(1.0% was forced.

    Full Text Available Background: Small and medium-sized enterprises (SMEs, especially in the Western Cape Province of South Africa, are currently facing various financial and other obstacles, which may threaten their survival. Globalisation, the lowering of trade barriers and the reduction of import tariffs have resulted in increased international competition. Businesses are thus forced to undertake continuous improvements and innovation in order to survive, to keep abreast of change and to excel.Objectives: Effective knowledge sharing and consequent knowledge management (KM have been identified as definite approaches to enhancing competitive advantage. The research therefore aimed to establish to what extent small enterprises embrace their knowledge sharing activities and whether their knowledge sharing activities are managed at all. Furthermore, it examined how their knowledge sharing can contribute to their competitive advantage.Method: A case study approach was followed for this research. Selected SMEs from the engineering sector were the subject of the case study and SME owners, directors and managers of consulting civil engineering firms were interviewed to determine whether there are mechanisms in place to ensure better knowledge sharing within SMEs.Results: In general, respondents had stated that they possessed special factors that set them above their competitors:• The company strategy and good reputation of completing projects within the required timeframe. In other words, they were well known for their track record in terms of service delivery. • Their specialty in terms of different focus areas, namely structural and civil engineering, water supply and storm water design, transportation, sewer design and storm water traffic. • The fact that they operated in silos. This means that the specialists in their specific fields operated independently in groups, separately from everyone else in the company. • Their good relationship with local authorities

    Background: In 2007, South Africa made family medicine a new speciality. Family physicians that have trained for this new speciality have been employed in the district health system since 2011. The aim of the present study was to explore the perceptions of district managers on the impact of family physicians on clinical processes, health system performance and health outcomes in the district health system (DHS) of the Western Cape. Methods: Nine in-depth interviews were performed: seven with district managers and two with the chief directors of the metropolitan and rural DHS. Interviews were recorded, transcribed and analysed using the ATLAS-ti and the framework method. Results: There was a positive impact on clinical processes for HIV/AIDS, TB, trauma, non-communicable chronic diseases, mental health, maternal and child health. Health system performance was positively impacted in terms of access, coordination, comprehensiveness and efficiency. An impact on health outcomes was anticipated. The impact was not uniform throughout the province due to different numbers of family physicians and different abilities to function optimally. There was also a perception that the positive impact attributed to family physicians was in the early stages of development. Unanticipated effects included concerns with their roles in management and training of students, as well as tensions with career medical officers. Conclusion: Early feedback from district managers suggests that where family physicians are employed and able to function optimally, they are making a significant impact on health system performance and the quality of clinical processes. In the longer term, this is likely to impact on health outcomes. Evaluation de l'impact des médecins de famille dans le système de santé du district du Western Cape, en Afrique du Sud.

    Interpersonal violence (IPV) and heavy alcohol consumption are major problems in the Western Cape Province of South Africa. Cranio-maxillofacial fractures, particularly nasal and zygomatic bone fractures, as well as isolated radial fractures (Colles fractures) and ulnar shaft fractures (parry fractures), are indicative of IPV, while alcoholic liver disease (ALD) is the consequence of chronic alcohol abuse. We therefore aim to investigate whether a significant association exists between the prevalence of cranio-maxillofacial fractures and parry fractures and ALD in a Western Cape population. Embalmed cadavers (n = 124) used for medical students' anatomy training at the Division of Anatomy and Histology, Faculty of Medicine and Health Sciences, Stellenbosch University were studied. The cadavers were dissected according to departmental protocol. The liver of each cadaver was investigated for macroscopic pathology lesions. Tissue samples were removed, processed to wax, and sectioned and stained with hematoxylin and eosin (H&E). All soft tissue was removed from the skulls, radii, and ulnae, which were then investigated for healed skeletal trauma. The results showed 37/124 (29.8%) cadavers had healed cranio-maxillofacial fractures and 24/124 (19.4%) cadavers had morphologic features of ALD. A total of 12/124 (9.7%) cadavers showed signs of both ALD and healed cranio-maxillofacial trauma. More males were affected than females, and left-sided facial fractures were statistically more common compared to the right side. This study illustrated a significant trend between alcohol abuse and cranio-maxillofacial fractures in individuals from communities with a low socio-economic status (SES) where IPV is a major problem.

    Full Text Available The private Grootbos Nature Reserve is located at the Western edge of the Agulhas Plain in the Cape Floristic Region of South Africa, an area characterized by high habitat and floristic diversity. The Reserve is covered in near-natural fynbos shrublands with a few patches of forest and wetland. The main objective of this study was to classify the vegetation into discrete units and relate them to the prevailing environmental conditions. The vegetation was analysed by numerical means (TWINSPAN, DC A, CCA and mapped on GIS. At the vegetation type level. Forest & Thicket and Fynbos formed distinctive clusters, whereas the wetland releves were intermixed, but without relationships to one of these units. Fire incidence served as the major determinant of the forest-fynbos boundary. The Forest & Thicket grouping was separated into Thicket (as transitional to fynbos, Afromontane Forest and Milkwood Scrub Forest. Two broad complexes were distinguished within the Fynbos grouping, the Alkaline Sand Fynbos Complex corresponding to Coastal Fynbos. and the Acid Sand Fynbos Complex corresponding to Mountain Fynbos. They discriminated along gradients of pH. soil depth and rock cover. The complexes were further subdivided into formations by using one or a few subjectively chosen dominant species as indicators. The transitions between these formations were rather continuous than discrete. The vegetation type and complex levels correspond well to existing fynbos-wide classifications. Comparing the formations to the results of other vegetation studies is problematic even on the scale of the Agulhas Plain, due to the high regional plant diversity in the Fynbos Biome.

  2. Pricing landfill externalities: Emissions and disamenity costs in Cape Town, South Africa

    International Nuclear Information System (INIS)

    Highlights: → The paper estimates landfill externalities associated with emissions, disamenities and transport. → Transport externalities vary from 24.22 to 31.42 Rands per tonne. → Costs of emissions (estimated using benefits transfer) vary from 0.07 to 28.91 Rands per tonne. → Disamenities (estimated using hedonic pricing) vary from 0.00 to 57.46 Rands per tonne. → Overall, external costs for urban landfills exceed those of a regional landfill. - Abstract: The external (environmental and social) costs of landfilling (e.g. emissions to air, soil and water; and 'disamenities' such as odours and pests) are difficult to quantify in monetary terms, and are therefore not generally reflected in waste disposal charges or taken into account in decision making regarding waste management options. This results in a bias against alternatives such as recycling, which may be more expensive than landfilling from a purely financial perspective, but preferable from an environmental and social perspective. There is therefore a need to quantify external costs in monetary terms, so that different disposal options can be compared on the basis of their overall costs to society (financial plus external costs). This study attempts to estimate the external costs of landfilling in the City of Cape Town for different scenarios, using the benefits transfer method (for emissions) and the hedonic pricing method (for disamenities). Both methods (in particular the process of transferring and adjusting estimates from one study site to another) are described in detail, allowing the procedures to be replicated elsewhere. The results show that external costs are currently R111 (in South African Rands, or approximately US$16) per tonne of waste, although these could decline under a scenario in which energy is recovered, or in which the existing urban landfills are replaced with a new regional landfill.

    Full Text Available The prevalence, distribution and demographic associations of refractive error in three communities in Cape Town, South Africa were assessed. In this cross-sectional study, a clustered random sampling procedure was used to recruit participants (n=176; age=40.6±14.7 years; males=76, females=96 from Khayelitsha, Milnerton, and Mitchell’s Plain. From March to May 2010, participants underwent autore-fraction and subjective refraction eye examinations.A structured interview was used to collect data on sociodemographics, age, gender, level of education, employment and race. Participants younger than 15 years, non-residents, or residents for less than six months, who declined signing the informed consent forms were excluded from the study. In this study myopia was defined as the spherical equivalent value in the better eye of −1.00D or worse and hyperopia as the spherical equivalent value in the better eye of ≥1.00D. Astigmatism was defined as −0.50 cylinder or worse in the better eye. The prevalence of myopia was 17.4% with a 90% confidence interval (CI of 12.65-22.15, hyperopia was 13.4% (90% CI 9.13-17.67, and astigmatism was 60% (90% CI 53.86-66.14. Myopia was found to be significantly associated with race and age; while hyperopia was significantly associated with age, employment and race. The results of this study may assist in planning for eye care on district level. (S Afr Optom 2012 71(1 32-38

  4. Knowledge, beliefs and attitudes of community health workers about hypertension in the Cape Peninsula, South Africa

    Full Text Available This article explores the perceptions and attitudes of community health workers (CHWs about hypertension. The level of knowledge of hypertension, as well as their personal attitude towards this is crucial in the style and quality of their interventions. CHWs, whose role in health promotion is being increasingly recognised, can help contain or reduce the prevalence of hypertension by influencing the community to adopt healthy lifestyles. Forty-three CHWs employed by Zanempilo in two study areas, Sites B and C in Khayelitsha in the Cape Peninsula, South Africa, were included in the study. Firstly, focus group discussions were conducted with 17 purposively selected CHWs to explore attitudes, beliefs and perceptions of hypertension. Secondly, interviews were conducted to assess their basic knowledge about causes, prevention and control of hypertension. The focus group discussions revealed that CHWs were uncertain about the causes of hypertension. They also found it difficult to grasp the fact that people without risk factors, such as overweight or a family history of hypertension, could be hypertensive. Many CHWs believe in traditional medicines and home-brewed beer as the best treatment for hypertension. They believe that people who take medical treatment become sicker and that their health deteriorates rapidly. Risk factors of hypertension mentioned during the structured interviews include inheritance, lack of physical activity, consuming lots of salty and fatty food. Conclusions drawn from the findings of the CHWs’ responses highlighted their insufficient knowledge about hypertension as a chronic disease of lifestyle. Meanwhile they are expected to play a role in stimulating community residents’ interest in the broad principle of preventive health maintenance and follow-up. Data obtained from this research can be used for the planning of health-promotion programmes. These should include preventing hypertension and improving primary management

  5. Virgilia divaricata may facilitate forest expansion in the afrotemperate forests of the southern Cape, South Africa

    Full Text Available Virgilia divaricata is a fast-growing nitrogen-fixing tree species often found on the margins of forest in the southern Cape of South Africa and is particularly abundant after fire. However, V. divaricatamay invade fynbos even in the absence of fire and it has been described as a forest precursor. We investigated whether V. divaricata enriches soil fertility after its invasion into fynbos areas adjacent to forests. We measured soil organic carbon and soil nutrients at four sites. At each site, three vegetation types (forest, V. divaricata and fynbos were examined on the same soil type and at the same elevation. Our results showed that, on average, soils taken from V. divaricata stands had higher nitrogen and phosphorus values than the adjacent fynbos soils, with either lower or similar values to the adjacent forest soils. Higher soil fertility under V. divaricata, together with their shading effect, may create conditions favourable for shade-loving forest species dependent on an efficient nutrient cycle in the topsoil layers, and less favourable for shade-hating fynbos species, which are generally adapted to low soil fertility. We suggest that the restoration of the nutrient cycle found in association with forest may be accelerated under V. divaricata compared with other forest precursor species, which has important consequences for the use of V. divaricata in ecosystem restoration.Conservation implications: Alien plantations in the Outeniqua Mountains are being phased out and the areas are being incorporated into the Garden Route National Park. Fynbos areas are increasingly being invaded by forest and thicket species owing to fire suppression in lower-lying areas. An improved understanding of the fynbos–forest boundary dynamics will aid in efficient management and restoration of these ecosystems.

  6. Late-Pleistocene avifaunas from Cape Wanbrow, Otago, South Island, New Zealand

    International Nuclear Information System (INIS)

    Fossil avifaunas from the Hillgrove Formation at Boatmans Harbour, Ruby Gully, and Old Rifle Butts, all on Cape Wanbrow, Oamaru, north-east Otago, are listed. The marine beach sands and gravels at Old Rifle Butts that form the lowest part of the Hillgrove Formation and overlie the palaeo-wave platform were deposited during the last interglacial ∼ 130-110 kyr BP (Oxygen Isotope Stage 5). There are a few small avifaunas (totalling 11 spp.) from these beach sediments (J41/f8710, f8214, f8227). The colluvial, valley-fill deposits in Ruby Gully and at its mouth are the youngest in the sequence. Radiocarbon dating indicates their emplacement between 27 and 34 kyr BP, or the later part of Oxygen Isotope Stage 3. If these ages are representative of the true age of the samples and not the limitations of radiocarbon technology, they indicate that these deposits in Ruby Gully are much younger than the beach deposits. Radiocarbon ages on a pitfall fauna from a small cave 3-4 m above the base of the Hillgrove Formation indicate that the cave fauna has a similar age as that in Ruby Gully. The dune and interdune waterlaid deposits at Old Rifle Butts (>2 m above the wave platform) may date from an unknown time between 100 and 35 kyr BP or be coeval with those in Ruby Gully. Fifty-three species of bird (32 land and freshwater taxa) are represented in the combined avifaunas making this the richest Pleistocene avifauna known from New Zealand. All bird taxa are known from Late Holocene avifaunas in the eastern South Island. Key taxa (Pachyornis elephantopus, Emeus crassus, Euryapteryx geranoides, Coturnix, Chenonetta, Cnemiornis, Harpagornis, Fulica, Porphyrio, Gallinula) indicate that the habitat was mainly grassland and shrubland. Tuatara, indeterminate skinks, and seals are also present. (author). 57 refs., 10 figs., 2 tabs

  7. Climatic controls on ecosystem resilience: Postfire regeneration in the Cape Floristic Region of South Africa.

    Conservation of biodiversity and natural resources in a changing climate requires understanding what controls ecosystem resilience to disturbance. This understanding is especially important in the fire-prone Mediterranean systems of the world. The fire frequency in these systems is sensitive to climate, and recent climate change has resulted in more frequent fires over the last few decades. However, the sensitivity of postfire recovery and biomass/fuel load accumulation to climate is less well understood than fire frequency despite its importance in driving the fire regime. In this study, we develop a hierarchical statistical framework to model postfire ecosystem recovery using satellite-derived observations of vegetation as a function of stand age, topography, and climate. In the Cape Floristic Region (CFR) of South Africa, a fire-prone biodiversity hotspot, we found strong postfire recovery gradients associated with climate resulting in faster recovery in regions with higher soil fertility, minimum July (winter) temperature, and mean January (summer) precipitation. Projections using an ensemble of 11 downscaled Coupled Model Intercomparison Project Phase 5 (CMIP5) general circulation models (GCMs) suggest that warmer winter temperatures in 2080-2100 will encourage faster postfire recovery across the region, which could further increase fire frequency due to faster fuel accumulation. However, some models project decreasing precipitation in the western CFR, which would slow recovery rates there, likely reducing fire frequency through lack of fuel and potentially driving local biome shifts from fynbos shrubland to nonburning semidesert vegetation. This simple yet powerful approach to making inferences from large, remotely sensed datasets has potential for wide application to modeling ecosystem resilience in disturbance-prone ecosystems globally.

  8. Behavioural and chemical evidence for multiple colonisation of the Argentine ant, Linepithema humile, in the Western Cape, South Africa

    2011-02-01

    Full Text Available Abstract Background The Argentine ant, Linepithema humile, is a widespread invasive ant species that has successfully established in nearly all continents across the globe. Argentine ants are characterised by a social structure known as unicoloniality, where territorial boundaries between nests are absent and intraspecific aggression is rare. This is particularly pronounced in introduced populations and results in the formation of large and spatially expansive supercolonies. Although it is amongst the most well studied of invasive ants, very little work has been done on this ant in South Africa. In this first study, we investigate the population structure of Argentine ants in South Africa. We use behavioural (aggression tests and chemical (CHC approaches to investigate the population structure of Argentine ants within the Western Cape, identify the number of supercolonies and infer number of introductions. Results Both the aggression assays and chemical data revealed that the Western Cape Argentine ant population can be divided into two behaviourally and chemically distinct supercolonies. Intraspecific aggression was evident between the two supercolonies of Argentine ants with ants able to discriminate among conspecific non-nestmates. This discrimination is linked to the divergence in cuticular hydrocarbon profiles of ants originating from the two supercolonies. Conclusions The presence of these two distinct supercolonies is suggestive of at least two independent introductions of this ant within the Western Cape. Moreover, the pattern of colonisation observed in this study, with the two colonies interspersed, is in agreement with global patterns of Argentine ant invasions. Our findings are of interest because recent studies show that Argentine ants from South Africa are different from those identified in other introduced ranges and therefore provide an opportunity to further understand factors that determine the distributional and spread

    Full Text Available Background: Service-learning (SL is a contested field of knowledge and issues of sustainability and scholarship have been raised about it. The South African Higher Education Quality Committee (HEQC has provided policy documents to guide higher education institutions (HEIs in the facilitation of SL institutionalisation in their academic programmes. An implementation framework was therefore needed to institutionalise the necessary epistemological shifts advocated in the national SL policy guidelines.Objectives: This article is based on the findings of a doctoral thesis that aimed at developing an SL implementation framework for the School of Nursing (SoN at the University of the Western Cape (UWC.Method: Mixed methods were used during the first four phases of the design and developmenti ntervention research model developed by Rothman and Thomas.Results: The SL implementation framework that was developed during Phase 3 specified the intervention elements to address the gaps that had been identified by the core findings of Phases 1 and 2. Four intervention elements were specified for the SL implementation framework. The first intervention element focused on the assessment of readiness for SL institutionalisation. The development of SL capacity and SL scholarship was regarded as the pivotal intervention element for three of the elements: the development of a contextual SL definition, an SL pedagogical model, and a monitoring and evaluation system for SL institutionalisation.Conclusion: The SL implementation framework satisfies the goals of SL institutionalisation, namely to develop a common language and a set of principles to guide practice, and to ensure the allocation of resources in order to facilitate the SL teaching methodology.The contextualised SL definition that was formulated for the SoN contributes to the SL operationalisation discourse at the HEI.

    Full Text Available This study evaluated commuter uptake of the bus rapid transit (BRT system in Cape Town,South Africa. As a stated preference survey was not carried out prior to the launch of the new BRT system in the City of Cape Town, it became difficult to assess commuters’ preferences,which would have provided City policymakers and planners with an understanding of customer satisfaction of the proposed bus service. The commuting trend of the BRT system in the City indicates that tickets sales and utilisation by commuters is gradually picking up, but one would have expected high commuter engagement in terms of the modernity profile of the BRT system. This study investigated commuters’ (n = 260 satisfaction levels with 30 service quality variables on a self-rated questionnaire, using quantitative research methodology.The study result showed that passengers were not satisfied with the transport fare and the availability or accessibility of ticket sales outlets. In the context of this study, this result implies that the ‘responsiveness and affordability’ variable of the service quality dimensions should be an area of interest and review to City of Cape Town policymakers and planners. Service quality trends in public transport were also highlighted.

  13. Feasibility of eradicating Ceratitis spp. fruit flies from the Western Cape of South Africa by the sterile insect technique

    International Nuclear Information System (INIS)

    Fruit production (deciduous fruit, table and wine grapes, and citrus) is a major export-based industry in the Western Cape, with more than 200,000 ha under cultivation. The gross value of these fruits (excluding wine) exceeds US$400 million per annum. Deciduous fruit and table grapes make up the major portion of the industry, with approximately 110,000 ha under production. The Western Cape is host to two species of fruit flies, the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), and the Natal fruit fly, C. rosa Karsch. One or both of these species attack at least 19 species of fruits in this area. Both species have very similar life cycles and habits, and can cause enormous crop losses especially to fruits, but also to some vegetables. Both commercial and resource-limited farmers are affected by fruit flies. Control of fruit flies is currently based on ground applications of insecticides, either as full-cover foliar sprays or low-volume bait sprays. Control costs and crop losses for deciduous fruit and table grapes alone are estimated at US$4 million annually. South Africa is the only southern hemisphere deciduous fruit-exporting country that is not fruit fly-free or is not currently engaged in a project to eradicate fruit flies. Unless similar steps are taken, this situation is likely to threaten the competitiveness of the Western Cape's industry. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture of the United Nations recently approved funding for the INFRUITEC Centre of the ARC-Fruit, Vine and Wine Research Institute in Stellenbosch to undertake a study to determine the feasibility of eradicating fruit flies from the Western Cape by the sterile insect technique (SIT). Most fruits in the Western Cape are produced in valley systems, and many valleys are isolated from one another to a greater or lesser extent. The Western Cape is itself well isolated from other areas with fruit fly hosts: by the ocean on the eastern, southern and

    Full Text Available Jung Un Jang,1 Inn-Jee Park2 1Department of Optometry, Eulji University, Seongnam, 2Department of Optometry, Kaya University, Gimhae, South Korea Purpose: To assess the prevalence of refractive errors among elementary school children in South Jeolla Province of South Korea. Methods: The subjects were aged 8–13 years; a total of 1,079 elementary school children from Mokpo, South Jeolla Province, were included. In all participants, uncorrected visual acuity and objective and subjective refractions were determined using auto Ref-Keratometer and phoropter. A spherical equivalent of -0.50 diopter (D or worse was defined as myopia, +0.50 D or more was defined as hyperopia, and a cylinder refraction greater than 0.75 D was defined as astigmatism. Results: Out of 1,079 elementary school children, the prevalence of uncorrected, best-corrected, and corrected visual acuity with own spectacles of 20/40 or worse in the better eye was 26.1%, 0.4%, and 20.2%, respectively. The uncorrected visual acuity was 20/200 or worse in the better eye in 5.7% of school children, and 5.2% of them already wore corrective spectacles. The prevalence of myopia, hyperopia, and astigmatism was 46.5% (95% confidence interval [CI]: 43.56–49.5, 6.2% (95% CI: 4.92–7.81, and 9.4% (95% CI: 7.76–11.25, respectively. Conclusion: The present study reveals a considerably higher prevalence of refractive error among elementary school children in South Jeolla Province of South Korea, exceeding 50% of subjects. The prevalence of myopia in the school children in Korea is similar to many other countries including People’s Republic of China, Malaysia, and Hong Kong. This may indicate that genetics and educational influences, such as studying and learning, may play a role in the progression of myopia in Korean elementary school children.

    Despite various HIV and AIDS training programmes offered for educators by the South African Department of Education, little has been achieved at the level of management in terms of creating a wider understanding of the social and cultural complexities of the condition and its impact on the quality of teaching and learning. Specifically, there is a lack of developmental programmes to help school principals provide leadership that can ensure that teachers and children who live in a context affected by the disease will still find themselves in a school environment of quality, care and compassion. With this in mind, we conducted a qualitative research enquiry among a sample of 12 school principals in the Eastern Cape Province in order to discover their perceptions about the impacts of HIV and AIDS on their schools and to learn how they have responded to the corresponding challenges. Our intention was to use the findings primarily to inform the development of an academic programme and short courses to empower school principals and leadership in this regard, but the findings may also be relevant as a guide for research on a larger scale.

    Full Text Available Sporadic outbreaks of aflatoxicosis occur in dogs when they consume contaminated dog food. During 2011, low-cost brands of pelleted dog food were contaminated with very high concentrations of aflatoxins. Approximately 100 dogs were presented to the Onderstepoort Veterinary Academic Hospital. Clinically, the dogs were depressed to collapsed and icteric, with haematemesis, melaena and haematochezia. The most common pathological findings were icterus, gastro-enterorrhagia and hepatosis. On histopathological examination, fatty hepatosis and bile duct proliferation were observed. A consistent, very characteristic finding was the presence of a blue-grey granular material within the bile ducts. A total of 124 samples of the dog food fed to the affected dogs was analysed to determine aflatoxin concentrations. Concentrations ranged from below the limit of quantification (< 5 μg/kg to 4946 μg/kg and six samples were submitted to determine the ratio of aflatoxins in the feed. It is estimated that well over 220 dogs died in the Gauteng Province of South Africa as a result of this aflatoxin outbreak.

    Information on changes in precipitation chemistry in the rapidly expanding Cape Metropolitan Area (CMA) of South Africa is scarce. To obtain a long-term record of N deposition we investigated changes in moss foliar N, C:N ratios and nitrogen isotope values that might reflect precipitation chemistry. Tissue from 9 species was obtained from herbarium specimens collected between 1875 and 2000 while field samples were collected in 2001/2002. There is a strong trend of increasing foliar N content in all mosses collected over the past century (1.32-1.69 %N). Differences exist between ectohydric mosses which have higher foliar N than the mixohydric group. C:N ratios declined while foliar {delta}{sup 15}N values showed no distinct pattern. From relationships between moss tissue N and N deposition rates we estimated an increase of 6-13 kg N ha{sup -1} a{sup -1} since 1950. Enhanced N deposition rates of this magnitude could lead to biodiversity losses in native ecosystems. - This study of bryophyte tissue nutrient contents shows a historical increase in N deposition rates to the low nutrient adapted plant biodiversity hotspot in the Western Cape, South Africa.

    2007-04-01

    Friedling and Morris (2005) have reported that intentional removal of incisors as a form of dental modification is relatively common in Cape Town. In this paper we further report on the style of modification and the reasons for the modification. A survey of eight adjoining areas in the northern suburbs of the Cape Town Metropole in the Western Cape was done to investigate the current prevalence of this practice. The survey was conducted by means of a questionnaire. Three groups of study subjects (scholars, working people and retired people) were included to gain a perspective of the community in general. The individual ages ranged from 15 to 83-years-old. A total of 2167 individuals participated in this study. Forty one percent had modified their teeth. More males (44,8%) than females (37,9%) were involved in this practice. Six "styles" of modification were identified. The removal of the upper four incisors was by far the most common modification (93,7%). There were four reported reasons for dental modification i.e. gangsterism, peer pressure, fashion and medical (dental) or accidental. More than two thirds (69,8%) of individuals with modifications also wore dentures. PMID:17612385

    Full Text Available Little is known about the nature and extent of alcohol and other drug (AOD use among pregnant women in Cape Town, South Africa, despite the very high levels of AOD use in this part of the country. A cross-sectional survey was conducted among pregnant women attending 11 Midwife Obstetric Units (MOUs in greater Cape Town. A two-stage cluster survey design was used. In total, 5231 pregnant women were screened to assess self-reported prevalence estimates. Of these, 684 (13.1% were intentionally subsampled and completed an interviewer-administered questionnaire and provided a urine sample for biological screening. Urinalyses showed that 8.8% (95% CI: 6.7–10.9 of the subsample tested positive for at least one illicit drug. This is higher than the self-reported prevalence (3.6%. In addition, 19.6% (95% CI: 16.3–22.8 of the sub-sample tested positive for alcohol which is lower than the self-reported prevalence (36.9%. There are high levels of substance use among pregnant women attending public sector antenatal clinics. There is a need for routine screening for AOD use and appropriate responses depending on the women’s level of risk.

    Duchenne muscular dystrophy (DMD) is one of the most common and severe of the inherited dystrophies, with an incidence of 1 in 3 500 live, male births worldwide. Becker muscular dystrophy (BMD) has a lower incidence of 1:14 000 - 18 000 boys and a milder progression and longer life expectancy. Over the last two decades, better understanding of the underlying disease aetiology as well as major advances in medical technology have brought about significantly improved genetic diagnosis and clinical care for B/DMD patients. Exciting developments in the field of gene-based therapies have once again put B/DMD in the limelight, with renewed focus on the importance of comprehensive genetic testing protocols. We present a historical overview of the medical and molecular service for B/DMD offered over the last three decades in South Africa, specifically in the Western Cape, from a clinical as well as a laboratory perspective.

    Quasi-simultaneous vertically resolved multiwavelength aerosol Raman lidar observations were conducted in the near field (Praia, Cape Verde, 15°N, 23.5°W) and in the far field (Manaus, Amazon basin, Brazil, 2.5°S, 60°W) of the long-range transport regime between West Africa and South America. Based on a unique data set (case study) of spectrally resolved backscatter and extinction coefficients, and of the depolarization ratio a detailed characterization of aerosol properties, vertical stratification, mixing, and aging behavior during the long-distance travel in February 2008 (dry season in western Africa, wet season in the Amazon basin) is presented. While highly stratified aerosol layers of dust and smoke up to 5.5 km height were found close to Africa, the aerosol over Manaus was almost well-mixed, reached up to 3.5 km, and mainly consisted of aged biomass burning smoke.

    Full Text Available Crude extracts of three actinomycetes species belonging to Saccharopolyspora (TR 046 and TR 039 and Actinosynnema (TR 024 genera were screened for antibacterial activities against a panel of several bacterial strains. The extracts showed antibacterial activities against both gram-negative and gram-positive test bacteria with inhibition zones ranging from 8 to 28 mm (TR 046; 8 to15 mm (TR 039; and 10 to 13 mm (TR 024. The minimum inhibitory concentrations ranged from 0.078 to 10 mg/mL (TR 046; 5 to >10 mg/mL (TR 039; and 1.25 to 5 mg/mL (TR 024. Time-kill studies revealed that crude extract of TR 046 showed strong bactericidal activity against Bacillus pumilus (ATCC14884, reducing the bacterial load by 104 cfu/mL and 102 cfu/mL at 4× MIC and 2× MIC, respectively, after 6 h of exposure. Similarly, against Proteus vulgaris (CSIR 0030, crude extract of TR 046 achieved a 0.9log10 and 0.13log10 cfu/mL reduction at 5 mg/mL (4× MIC and 1.25 mg/mL (2× MIC after 12 h of exposure. The extract was however weakly bactericidal against two environmental bacterial strains (Klebsiella pneumoniae and Staphylococcus epidermidis; and against Pseudomonas aeruginosa (ATCC 19582: the extract showed bacteriostatic activities at all concentrations tested. These freshwater actinomycetes appear to have immense potential as a source of new antibacterial compound(s.

  16. Initial review and analysis of the direct environmental impacts of CSP in the northern Cape, South Africa

    2016-05-01

    The Integrated Resource Plan (IRP) of 2010 and the IRP Update provide the most recent guidance to the electricity generation future of South Africa (SA) and both plans include an increased proportion of renewable energy generation capacity. Given that SA has abundant renewable energy resource potential, this inclusion is welcome. Only 600 MW of the capacity allocated to concentrating solar power (CSP) has been committed to projects in the Northern Cape and represents roughly a fifth of the capacity that has been included in the IRP. Although CSP is particularly new in the electricity generation system of the country, the abundant solar resources of the region with annual DNI values of above 2900 kWh/m2 across the arid Savannah and Nama-Karoo biomes offer a promising future for the development of CSP in South Africa. These areas have largely been left untouched by technological development activities and thus renewable energy projects present a variety of possible direct and indirect environmental, social and economic impacts. Environmental Impact Assessments do focus on local impacts, but given that ecological processes often extend to regional- and landscape scales, understanding this scaled context is important to the alignment of development- and conservation priorities. Given the capacities allocated to CSP for the future of SA's electricity generation system, impacts on land, air, water and biodiversity which are associated with CSP are expected to increase in distribution and the understanding thereof deems valuable already from this early point in CSP's future in SA. We provide a review of direct impacts of CSP on the natural environment and an overview of the anticipated specific significance thereof in the Northern Cape.

  17. Condom negotiation, HIV testing, and HIV risks among women from alcohol serving venues in Cape Town, South Africa.

    Eileen V Pitpitan

    Full Text Available BACKGROUND: Women in South Africa are at particularly high-risk for HIV infection and are dependent on their male partners' use of condoms for sexual risk reduction. However, many women are afraid to discuss condoms with male partners, placing them at higher risk of HIV infection. PURPOSE: To examine the association between fear of condom negotiation with HIV testing and transmission risk behaviors, including alcohol use and sexual risks among South African women. METHOD: Women (N = 1333 residing in a primarily Xhosa-speaking African township in Cape Town and attending informal alcohol-serving venues (shebeens completed anonymous surveys. Logistic regression was used to test the hypothesis that fear of condom negotiation would be associated with increased risk for HIV. RESULTS: Compared to women who did not fear condom negotiation, those who did were significantly less likely to have been tested for HIV, were more likely to have experienced relationship abuse, and to report more alcohol use and more unprotected sex. CONCLUSIONS: For women in South Africa, fear of condom negotiation is related to higher risk of HIV. HIV prevention efforts, including targeted HIV counseling and testing, must directly address gender issues.

  18. A Critical Appraisal of Western Cape Forum for Intellectual Disability V Government of the Republic of South Africa

    2015-12-01

    Full Text Available The 2011 the Western Cape Forum for Intellectual Disability v Government of The Republic of South Africa case flagged a lot of issues faced by persons with disabilities relating to access to education in South Africa. The case tackled certain perceptions about the ineducability of persons with profound and severe disability and the remaining charity-oriented perception by the South African Department of Basic Education. While the court made several important points in advancing universal access to education, the author argues that certain holes in the judgment hinders the existence of judicial finding truly infused with concerns of substantive equality. An example of this short-coming is the court's consideration of reasonableness when the right to basic education is an immediately realisable right. The author also argues that the South African developments in education policy for persons with disability, while positive, is insufficient to truly give effect to substantive equality – the claim to equality being made in the new constitutional dispensation. There is still an attitude that is too permissive of separating students based on abilism. The social model of thinking about requires a complete transformation of the education system that would not require a classification of learners by abilities but have a different constitution so as to accommodate all students and not unduly enable one group over another. The author considers the approaches from Canada and India to explore its responses to education for students with varying levels of ability. Canada's similar conception of equality and India's influence on South African constitutionalism and shared experience with massive equality gaps make these jurisdictions instructive.

    2015-02-01

    Full Text Available Introduction: Concurrent partnerships (CPs have been suggested as a risk factor for transmitting HIV, but their impact on the epidemic depends upon how prevalent they are in populations, the average number of CPs an individual has and the length of time they overlap. However, estimates of prevalence of CPs in Southern Africa vary widely, and the duration of overlap in these relationships is poorly documented. We aim to characterize concurrency in a more accurate and complete manner, using data from three disadvantaged communities of Cape Town, South Africa. Methods: We conducted a sexual behaviour survey (n=878 from June 2011 to February 2012 in Cape Town, using Audio Computer-Assisted Self-Interviewing to collect sexual relationship histories on partners in the past year. Using the beginning and end dates for the partnerships, we calculated the point prevalence, the cumulative prevalence and the incidence rate of CPs, as well as the duration of overlap for relationships begun in the previous year. Linear and binomial regression models were used to quantify race (black vs. coloured and sex differences in the duration of overlap and relative risk of having CPs in the past year. Results: The overall point prevalence of CPs six months before the survey was 8.4%: 13.4% for black men, 1.9% for coloured men, 7.8% black women and 5.6% for coloured women. The median duration of overlap in CPs was 7.5 weeks. Women had less risk of CPs in the previous year than men (RR 0.43; 95% CI: 0.32–0.57 and black participants were more at risk than coloured participants (RR 1.86; 95% CI: 1.17–2.97. Conclusions: Our results indicate that in this population the prevalence of CPs is relatively high and is characterized by overlaps of long duration, implying there may be opportunities for HIV to be transmitted to concurrent partners.

  3. The relationship between wellbeing indicators and teacher psychological stress in Eastern Cape public schools in South Africa

    Malik L.M. Vazi

    2013-01-01

    Full Text Available Orientation: Positive psychological and subjective wellbeing indicators have proven to be protective against certain physical illnesses but have been rarely assessed in teacher stress.Research purpose: The main objective of this study was to assess the relationship between indicators of wellbeing and stress and to further assess the relative importance of these wellbeing indicators in explaining stress variance in a large sample of Eastern Cape primary and high school teachers in South Africa.Motivation for the study: The majority of teacher stress studies focus on the misfit between the individual’s resources and the environmental demands. There is a scarcity of studies reporting on protective factors in teaching and we know little about their possible role as possible protective factors against stress. This is important in developing stress prevention strategies.Research design, approach and method: A cross-sectional survey was used targeting public school teachers in the Eastern Cape. The sample size was 562 randomly selected teachers from both public primary and high schools.Main findings: The results revealed that stress is prevalent amongst teachers. Subjective and psychological wellbeing factors added significantly to the explained stress variance. Also, both negative affect and role problems had significant positive correlations with stress, whilst psychological wellbeing had a strong inverse relationship with stress.Practical/managerial implications: The results implied that interventions focusing on improving psychological wellbeing and reduction of negative affect can contribute to stress prevention.Contribution/value-add: The results contributed towards a better understanding of the relative importance of wellbeing constructs as protective factors against teacher stress.

  4. The clinical and molecular spectrum of galactosemia in patients from the Cape Town region of South Africa

    2002-09-01

    Full Text Available Abstract Background The objective of this study was to document the clinical, laboratory and genetic features of galactosemia in patients from the Cape Town metropolitan region. Methods Diagnoses were based on thin layer chromatography for galactosuria/galactosemia and assays of erythrocyte galactose-1-phosphate uridyltransferase (GALT and galactokinase activities. Patients were screened for the common S135L and Q188R transferase gene mutations, using PCR-based assays. Screening for the S135L mutation in black newborns was used to estimate the carrier rate for galactosemia in black South Africans. Results A positive diagnosis of galactosemia was made in 17 patients between the years 1980 to 2001. All had very low or absent galactose-1-phosphate uridyltransferase (GALT activity, and normal galactokinase levels. The mean age at diagnosis was 5.1 months (range 4 days to 6.5 months. A review of 9 patients showed that hepatomegaly (9/9, and splenomegaly, failure to thrive, developmental delay, bilateral cataracts (6/9 were the most frequent features at diagnosis. Six had conjugated hyperbilirubinemia. Four experienced invasive E. coli infection before diagnosis. Ten patients were submitted to DNA analysis. All 4 black patients and 2 of mixed extraction were homozygous for the S135L allele, while all 3 white patients were homozygous for the Q188R allele. The remaining patient of mixed extraction was heterozygous for the Q188R allele. The estimated carrier frequency of the S135L mutation in 725 healthy black newborns was 1/60. Conclusions In the absence of newborn screening the delay in diagnosis is most often unacceptably long. Also, carrier frequency data predict a galactosemia incidence of approximately 1/14 400 for black newborns in the Cape Metropole, which is much higher than the current detection rate. It is thus likely that many patients go undetected.

  5. Baseline air mass selection at Cape Point, South Africa: application of 222Rn and other filter criteria to CO2

    International Nuclear Information System (INIS)

    Concentrations of 222Rn (March 1999-August 2002) from a recently installed analyser at the station Cape Point (34oS, 18oE), South Africa, were analysed statistically. The combination of 222Rn with information on wind direction and carbon monoxide (CO) permitted a classification of air masses into continental, marine, and mixtures of both. The ability to select trace gas data representing purely maritime conditions is shown through application to carbon dioxide (CO2) data. 222Rn levels at Cape Point ranged from near zero to above 5000 mBq m-3. Monthly percentiles show practically no seasonal dependence for values up to the 25th percentile (P25), corresponding to 222Rn -3 which is considered typical for marine air. In contrast, 222Rn percentiles exceeding P50 reveal an austral winter maximum, related to a higher incidence of continental air at that time of the year. The wind sector pattern for 222Rn concentrations largely coincides with that observed for CO, but covers a wider sector to the east, reflecting continental source areas. Air masses with 222Rn levels between 100 and 250 mBq m-3 were found to be still affected by terrestrial sources. Our routinely used percentile-based statistical filter applied to CO2 accepted 222Rn -3), which only yielded 18%, but is more stringent in excluding terrestrial influences. CO2 data filtered by using a combination of various selection parameters agreed well with data obtained for 222Rn -3, confirming that this 222Rn threshold is a suitable criterion for purely maritime data. Nonetheless, for CO2 the statistical filter, which does not depend on other species and has better data coverage, still retains its applicability for routine trace gas filtering with respect to baseline concentrations.

    According to the analysis on the characteristics of historic earthquakes in Jiangsu Province and South Huanghai Sea region, the historical earthquakes in the studied area are divided into two kinds of"comparatively safe class"and"comparatively dangerous class". Then the statistical result of earthquake class, the characteristics of geographical distribution and geological structures are studied. The study shows: a) In Jiangsu Province and South Huanghai Sea region, the majority of historical strong earthquakes belong to"comparatively safe class", only 13.8% belong to"comparatively dangerous class"; b) Most historical earthquakes belong to"comparatively safe class" in the land area of Jiangsu, eastern sea area of Yangtze River mouth and northern depression of South Huanghai Sea region. However, along the coast of middle Jiangsu Province and in the sea area of South Huanghai Sea, the distribution of historical earthquake classes is complex and the earthquake series of"comparatively dangerous class"and"comparatively safe class"are equivalent in number; c) In the studied area, the statistical results of historical earthquake classes and the characteristics of spatial distribution accord very well with the real case of present-day earthquake series. It shows that the seismic activity in the region has the characteristic of succession, and the result from this study can be used as a reference for early postseismic judgment in the earthquake emergency work in Jiangsu Province.

    Full Text Available This study used permanently marked 50 m: sites, surveyed at a 30 year interval, to provide a descriptive account of the temporal change in the fynbos vegetation of the Cape of Good Hope Nature Reserve. South Africa. Management records were used to examine the role of post-fire age. fire frequency and intensity, as well as biotic interactions (competition from overstorey proteoids and alien plants in influencing vegetation composition over this time period. The mean similarity in species composition of sites between surveys was 62%, indicating an average of nearly 40% turnover in species over the 30 year period. The main causes of this change included differences resulting from different stages in the post-fire succession as well as the impact of differential fire regimes (especially frequency effects. Competition from serotinous Proteaceae. which proved highly mobile after fire, as well as invasive Australian acacias also impacted on the composition of the vegetation over time. The study demonstrated that fynbos communities are temporally dynamic and that the changes over time in species composition are caused by a variety of processes. The study also provided evidence for the role of temporal diversity in contributing to the high species diversity in fynbos systems.

    Full Text Available Abstract Background This prospective study investigated the association between life-long methamphetamine and other drug use and high school non-attendance, in a sample of high school students in Cape Town, South Africa. Methods A random sample of 1535 high school students completed a baseline questionnaire in 2006, and were asked to complete a follow-up questionnaire 12 months later. The questionnaire included questions on substance use, including tobacco, alcohol, methamphetamine and cannabis use, demographic factors, and questions relating to school attendance and performance. Results Forty-three percent of the students surveyed at baseline did not complete a follow-up questionnaire after 12 months. Compared with students who were not using selected substances, an adjusted logistic regression model showed that life-time methamphetamine use in addition to other substances was significantly associated with non-attendance (OR = 2.58, 95% CI: 1.24 - 5.36 when other non-substance use factors (repeating a year at school and being older than the norm for current grade were taken into account. Conclusions Early identification of students with methamphetamine and other substance use problems, and a supportive rather than punitive school policy, may be valuable in improving high school completion and student retention rates.

    Full Text Available The December 2004-January 2005 floods in the Garden Route region of the Southern Cape in South Africa have had a significant impact on local development and economic activities, tourism products andlocal institutions. This article aims to capture the dynamism between a number of related fields within the context of transdisciplinary research. Qualitative research methods were used to target a representative sample of the affected population. This article considers the history of the flooding events of December 2004/January 2005 along the Garden Route, as well as the manner in which emergency/disaster management personnel responded to the crisis. The effect of the floods on the tourism sector along the Garden Route was researched in general and the effects of the floods on tourists, local residents, and particularly communities in disadvantaged areas were specifically determined. The research reflects on the disaster risk management strategies that were in place at the time of the floods to determine what local authorities could have done to cope with the potential conditions of crisis. The research found that although some tourism products were severely affected, the 2004/2005 floods did not have a significant impact on the number of tourists frequenting the area. In terms of disaster risk management, concerns remain regarding the lack of the following factors: capacity, adequate early warning systems, proper infrastructure maintenance, local institutions, and an in-depth understanding of the disaster risk profile of the area.

    Full Text Available Wild harvesting has taken place over millennia in Africa. However urbanization and cash economies have effectively altered harvesting from being cultural, traditional, and subsistence activities that are part of a rural norm, to being a subculture of commonly illicit activities located primarily within the urban, cash-based, informal economy. This paper focuses on Cape Town, South Africa where high levels of poverty and extensive population growth have led to a rapidly growing informal industry based on the cultural, subsistence, and entrepreneurial harvesting and consumption of products obtained from the local natural environment. Through a process of literature reviews, database analysis, and key informant interviews, a compendium of harvested species was developed, illustrating the breadth of illicit harvesting of products from nature reserves, public open space, and other commonage within the City. The compendium records 448 locally occurring species (198 animals and 250 plants that are extracted for medicinal, energy, ornamental, sustenance, nursery, and other uses. The sustainability of harvesting is questionable; nearly 70% of all harvested flora and 100% of all collected fauna are either killed or reproductively harmed through the harvesting processes. Furthermore, for the 183 indigenous flora species currently recorded on the International Union for Conservation of Nature (IUCN Red List, 28% (51 hold assessments ranging from Declining through to Critically Endangered. With respect to the more poorly assessed fauna (46 spp., approximately 24% (11 have Declining or Threatened status.

    South Africa is facing an established epidemic of methamphetamine, known locally as "tik." Globally, methamphetamine has been linked to high rates of sexual risk behaviors, including sex trading. The goal of this study was to qualitatively examine the experiences of sex trading among methamphetamine users in Cape Town, South Africa. Individual in-depth interviews were conducted with 30 active methamphetamine users (17 men and 13 women) recruited from the community. Interviews were conducted in local languages using a semi-structured guide that included questions on sex trading experiences and perceptions of sex trading among methamphetamine users. Interviews were audio-recorded, transcribed, and analyzed using analytic memos and coding with constant comparison techniques. The data revealed that in a setting of high levels of addiction and poverty, sex was an important commodity for acquiring methamphetamine. Women were more likely to use sex to acquire methamphetamine, but men reported opportunistic cases of trading sex for methamphetamine. Four models of sex trading emerged: negotiated exchange, implicit exchange, relationships based on resources, and facilitating sex exchange for others. The expectation of sex trading created a context in which sexual violence against female methamphetamine users was common. Multiple sexual partners and inconsistent condom use in acts of sex trading put methamphetamine users at high risk of HIV. Interventions in this setting should address addiction, which is the primary driver of sex trading among methamphetamine users. Harm reduction interventions may include education about HIV and other sexually transmitted infections, availability of condoms and HIV testing, and sexual violence prevention. PMID:25567071

    Full Text Available Environmental factors during childhood are thought to play a role in the aetiolgy of Crohn's Disease (CD. However the association between age at time of exposure and the subsequent development of CD in South Africa is unknown.A case control study of all consecutive CD patients seen at 2 large inflammatory bowel disease (IBD referral centers in the Western Cape, South Africa between September 2011 and January 2013 was performed. Numerous environmental exposures during 3 age intervals; 0-5, 6-10 and 11-18 years were extracted using an investigator administered questionnaire. An agreement analysis was performed to determine the reliability of questionnaire data for all the relevant variables.This study included 194 CD patients and 213 controls. On multiple logistic regression analysis, a number of childhood environmental exposures during the 3 age interval were significantly associated with the risk of developing CD. During the age interval 6-10 years, never having had consumed unpasteurized milk (OR = 5.84; 95% CI, 2.73-13.53 and never having a donkey, horse, sheep or cow on the property (OR = 2.48; 95% CI, 1.09-5.98 significantly increased the risk of developing future CD. During the age interval 11-18 years, an independent risk-association was identified for; never having consumed unpasteurized milk (OR = 2.60; 95% CI, 1.17-6.10 and second-hand cigarette smoke exposure (OR = 1.93; 95% CI, 1.13-3.35.This study demonstrates that both limited microbial exposures and exposure to second-hand cigarette smoke during childhood is associated with future development of CD.

    Small-scale subsistence farmers in South Africa have been introduced to genetically modified (GM) crops for more than a decade. Little is known about i) the extent of transgene introgression into locally recycled seed, ii) what short and long-term ecological and socioeconomic impacts such mixing of seeds might have, iii) how the farmers perceive GM crops, and iv) to what degree approval conditions are followed and controlled. This study conducted in the Eastern Cape, South Africa, aims primarily at addressing the first of these issues. We analysed for transgenes in 796 individual maize plants (leaves) and 20 seed batches collected in a village where GM insect resistant maize was previously promoted and grown as part of an governmental agricultural development program over a seven year period (2001-2008). Additionally, we surveyed the varieties of maize grown and the farmers' practices of recycling and sharing of seed in the same community (26 farmers were interviewed). Recycling and sharing of seeds were common in the community and may contribute to spread and persistence of transgenes in maize on a local or regional level. By analysing DNA we found that the commonly used transgene promoter p35s occurred in one of the 796 leaf samples (0.0013%) and in five of the 20 seed samples (25%). Three of the 20 seed samples (15%) included herbicide tolerant maize (NK603) intentionally grown by the farmers from seed bought from local seed retailers or acquired through a currently running agricultural development program. The two remaining positive seed samples (10%) included genes for insect resistance (from MON810). In both cases the farmers were unaware of the transgenes present. In conclusion, we demonstrate that transgenes are mixed into seed storages of small-scale farming communities where recycling and sharing of seeds are common, i.e. spread beyond the control of the formal seed system.

    Full Text Available BACKGROUND: Antiretroviral therapy (ART has been scaled-up rapidly in Africa. Programme reports typically focus on loss to follow-up and mortality among patients receiving ART. However, little is known about linkage and retention in care of individuals prior to starting ART. METHODOLOGY: Data on adult residents from a periurban community in Cape Town were collected at a primary care clinic and hospital. HIV testing registers, CD4 count results provided by the National Health Laboratory System and ART registers were linked. A random sample (n = 885 was drawn from adults testing HIV positive through antenatal care, sexual transmitted disease and voluntary testing and counseling services between January 2004 and March 2009. All adults (n = 103 testing HIV positive through TB services during the same time period were also included in the study. Linkage to HIV care was defined as attending for a CD4 count measurement within 6 months of HIV diagnosis. Linkage to ART care was defined as initiating ART within 6 months of HIV diagnosis in individuals with a CD4 count ≤200 cells/µl taken within 6 months of HIV diagnosis. FINDINGS: Only 62.6% of individuals attended for a CD4 count measurement within 6 months of testing HIV positive. Individuals testing through sexually transmitted infection services had the best (84.1% and individuals testing on their own initiative (53.5% the worst linkage to HIV care. One third of individuals with timely CD4 counts were eligible for ART and 66.7% of those were successfully linked to ART care. Linkage to ART care was highest among antenatal care clients. Among individuals not yet eligible for ART only 46.3% had a repeat CD4 count. Linkage to HIV care improved in patients tested in more recent calendar period. CONCLUSION: Linkage to HIV and ART care was low in this poor peri-urban community despite free services available within close proximity. More efforts are needed to link VCT scale-up to subsequent care.

    The Steenkampskraal Monazite Mine was first established in 1952, to extract monazite ore for the production of thorium and rare earth element (REE) concentrate. Refurbishment of the mine in recent years has required the re-inspection and re-evaluation of the mineralized monazite zone (MMZ). This contribution presents a structural review of the MMZ and its emplacement, based on recent data and its setting at the southern extent of the Bushmanland Sub-province of the Namaqua-Natal Metamorphic Belt. New surface and underground mapping confirm that the MMZ is a moderately-dipping body within gneissic host rocks on the southern limb of a broad F3 antiform. Thickness variations, both down-dip and along-strike, are the result of D2 and D3 deformation. The MMZ has been locally transected and steepened by subsequent late-D3, "steep-structures", which are typical of the Okiep copper district, ∼150 km north of Steenkampskraal. Geochronological data suggest that the MMZ was intruded, emplaced or formed at 1046 ± 7.5 Ma, at the start of the D3 Klondikean Episode (1040-1020 Ma). Unlike the analogous copper-bearing Koperberg Suite in the Okiep Copper district, the MMZ was not intruded into Klondikean-aged steep structures, but was rather transected and steepened by these. Local steepening of the otherwise moderately-dipping to flat-lying MMZ makes it locally amenable to detection by soil sampling and radiometric surveys.

    Full Text Available INTRODUCTION: Interpersonal violence in South Africa is the second highest contributor to the burden of disease after HIV/AIDS and 62% is estimated to be from intimate partner violence (IPV. This study aimed to evaluate how women experiencing IPV present in primary care, how often IPV is recognized by health care practitioners and what other diagnoses are made. METHODS: At two urban and three rural community health centres, health practitioners were trained to screen all women for IPV over a period of up to 8 weeks. Medical records of 114 thus identified women were then examined and their reasons for encounter (RFE and diagnoses over the previous 2-years were coded using the International Classification of Primary Care. Three focus group interviews were held with the practitioners and interviews with the facility managers to explore their experience of screening. RESULTS: IPV was previously recognized in 11 women (9.6%. Women presented with a variety of RFE that should raise the index of suspicion for IPV- headache, request for psychiatric medication, sleep disturbance, tiredness, assault, feeling anxious and depressed. Depression was the commonest diagnosis. Interviews identified key issues that prevented health practitioners from screening. CONCLUSION: This study demonstrated that recognition of women with IPV is very low in South African primary care and adds useful new information on how women present to ambulatory health services. These findings offer key cues that can be used to improve selective case finding for IPV in resource-poor settings. Universal screening was not supported by this study.

This study surveyed the occurrence and distribution of ticks infesting livestock across the North West province, South Africa. During three phases in consecutive years, officers of the provincial Veterinary Department collected specimens monthly from livestock hosts at specified sites across the province. Data analysis constituted the fourth phase of the study. A total of 1090 collections from 265 sites yielded 42 566 tick specimens, comprising 22 different tick species (18 ixodids, 4 argasids. The specimens represent all of the major tick vectors of disease that occur in South Africa. The major tick-borne diseases (i.e. heartwater, both African and Asiatic bovine babesiosis and anaplasmosis were found to be prevalent mainly in the north-eastern region of the province, which also displayed the highest tick species diversity. The central region appears transitory to some of the major vectors. Although some tick species were contained within specific regions, others were widespread across the province. Associated serology data show that most herds sampled in areas endemic for babesiosis and anaplasmosis in the north-eastern region are endemically unstable and at risk to these tick-borne diseases should vector control measures become ineffective.

    The main purpose of this study was to determine the economic contribution of tourism to selected provinces of South Africa. One of the reasons why this research is important is the fact that tourism is not reported as an industry in the national accounts, and this makes it very difficult to determine the economic impact of tourism. Most other sectors contain tourism related activities in their estimates and therefore tourism's economic contribution is greater than it seems at first. The under...

    Full Text Available Background: The majority of individuals report a decline in health-related quality of life following a stroke. Quality of life and factors predicting quality of life could differ in individuals from lower income countries. The aim of this study was therefore to determine the quality of life and factors influencing quality of life of community-dwelling stroke patients living in low-income, peri-urban areas in the Western Cape, South Africa.Method: An observational, longitudinal study was used to collect data from a conveniently selected sample of first-ever stroke patients. The Rivermead Motor Assessment Scale and the Barthel Index were used to determine functional outcome and the EQ-5D was used to collect information relating to quality of life at two months and six months poststroke. Descriptive and inferential statistics were used to analyse the data.Results: The total sample of 100 participants consisted of 50% men and 50% women with a mean age of 61 and a standard deviation of 10.55 years. Six-month quality of life datawas analysed for 73 of the 100 participants. Of the 27 who were lost to follow-up, nine participants died, four withdrew from the study after baseline data was collected and eleven could not be followed up as they had either moved or no follow-up telephone numbers were available. A further three participants were excluded from the analysis of the EQ-5D as they were aphasic. Of these, approximately 35% had problems with mobility and self-care, whilst 42% had severe problems with everyday activities and 37.8% expressed having anxiety and depression. Quality of life at two months (p = 0.010 and urinary incontinence (p = 0.002 were significant predictors of quality of life at six months.Conclusion: Health-related quality of life was decreased in the South African stroke sample. Functional ability and urinary incontinence were the factors affecting quality of life in the sample. These factors should be considered in the

    Full Text Available Background: Sexual violence in South Africa is a major public health and social problem. Sexual assault or rape is a traumatic event which disrupts not only the life of the female rape victim, but also that of her male intimate partner (MIP, irrespective of whether he witnessed or was informed of the incident. Objectives: The study aimed to explore the lived experiences of MIPs of female rape victims and the meaning of these experiences in the six months following the partner’s rape. Method: We conducted a longitudinal hermeneutic phenomenological study. Nine purposively sampled adult MIPs were interviewed over a period of six months. The participants were in an intimate relationship with a female rape victim prior to and immediately after the rape; their partners had been treated at a specialised centre for victims of rape and sexual assault. Four interviews were conducted with each of the nine intimate partners of female rape victims: (1 within 14 days of, (2 a month after, (3 three months after, and (4 six months after the rape. Results: Two major themes emerged: being-in-the-world as a secondary victim of rape, and living in multiple worlds, those of their female partners, family, friends, society, employers or colleagues, professionals and the justice system. The participant’s familiar world became strange and even threatening, and his relationship with his partner became uncertain. Conclusion: Early supportive intervention for intimate partners of female rape victims is required to prevent on-going emotional trauma and alleviate the effects of chronic post-traumatic stress disorder and suffering at intra- and interpersonal levels.

    Full Text Available Background: Schoenefeldia is a genus of C4 grasses, consisting of two species in Africa, Madagascar and India. It is the only representative of the genus found in southern Africa, where it was previously only known from a few collections in the southern part of the Kruger National Park (Mpumalanga Province, South Africa, dating from the early 1980s.Objectives: The objective of this study was to document a newly recorded population of Schoenefeldia transiens in an area that is exploited for coal mining.Method: A specimen of S. transiens was collected between Musina and Pontdrift, about 30 km east of Mapungubwe National Park, in the Limpopo Province of South Africa. The specimen was identified at the National Herbarium (Pretoria.Results: This is not only a new distribution record for the quarter degree grid (QDS: 2229BA, but is also the first record of this grass in the Limpopo Province. The population of S. transiens has already been fragmented and partially destroyed because of mining activities and is under serious threat of total destruction.Conclusion: It is proposed that the population of S. transiens must be considered to be of conservation significance, and the population should be made a high priority in the overall environmental management programme of the mining company that owns the land.

    A paleomagnetic studystudywork was carried out on the Alto Paraguay Province (APP), a belt of alkaline complexes that parallel the Paraguay river for more than 40 km at the border of Brazil and Paraguay. The province is well dated by 40Ar/39Ar method giving ages in the range 240-250 Ma with a preferred age of 241 Ma. Intrusive rocks are predominant but the stocks may be topped by lava flows and ignimbrites. Paleomagnetic work on stocks, dikes and flows of the APP identified normal and reversed magnetic components which are carried mainly by titanomagnetites. The calculated paleomagnetic pole located at 319ºE 78ºS (α95 = 6º; k = 23) is in agreement with other South American poles of Permo-Triassic age. Most of the sampling sites showed large variations in rock magnetization, but similar patterns in the variation of the within-site magnetizations, mainly in dikes, suggest geomagnetic polarity transition records. The magnetization data along with the anisotropy of magnetic susceptibility determinations suggested that the South and North areas of the province have different evolution characteristics.

  3. Strontium isotope investigation of ungulate movement patterns on the Pleistocene Paleo-Agulhas Plain of the Greater Cape Floristic Region, South Africa

    Middle Stone Age sites located within the Greater Cape Floristic Region on the South African southern coast have material culture with early evidence for key modern human behaviors such as projectile weaponry, large animal hunting, and symbolic behavior. In order to interpret how and why these changes evolved, it is necessary to understand their ecological context as it has direct relevance to foraging behavior. During periods of lowered sea level, a largely flat and vast expanse of land existed south of the modern coastline, but it is now submerged by higher sea levels. This exposed area, the Paleo-Agulhas Plain, likely created an ecological context unlike anything in the region today, as evidenced by fossil assemblages dominated by migratory ungulates. One hypothesis is that the Paleo-Agulhas Plain supported a migration ecosystem of large grazers driven by summer rainfall, producing palatable forage during summer in the east, and winter rainfall, producing palatable forage during winter in the west. Alternatively, ungulates may have been moving from the coastal plain in the south to the interior north of the Cape Fold Mountains, as observed for elephants in historic times. In this study, we assess ungulate movement patterns with inter- and intra-tooth enamel samples for strontium isotopes in fossil fauna from Pinnacle Point sites PP13B and PP30. To accomplish our goals we created a bioavailable 87Sr/86Sr isoscape for the region by collecting plants at 171 sampling sites and developing a geospatial model. The strontium isotope results indicate that ungulates spent most of their time on the Paleo-Agulhas Plain and avoided dissected plain, foothill, and mountain habitats located more than about 15 km north of the modern coastline. The results clearly exclude a north-south (coastal-interior) movement or migration pattern, and cannot falsify the east-west movements hypothesized in the south coast migration ecosystem hypothesis.

    In this study, we thoroughly analyzed spatial and temporal distributions of runoff and their relation with precipitation changes based on monthly runoff dataset at 25 hydrological stations and monthly precipitation at 127 stations in Guangdong Province, south China. Trends of the runoff and precipitation are detected using Mann-Kendall trend test technique. Correlations between runoff and precipitation are tested using Spearman's and Pearson's correlation coefficients. The results indicate that: (1) annual maximum monthly runoff is mainly in decreasing tendency and significant increasing annual minimum monthly runoff is observed in the northern and eastern Guangdong Province. In addition, annual mean runoff is observed to be increasing at the stations located in the West and North Rivers and the coastal region; (2) analysis of seasonal runoff variations indicates increasing runoff in spring, autumn and winter. Wherein, significant increase of runoff is found at 8 stations and only 3 stations are dominated by decreasing runoff in winter; (3) runoff changes of the Guangdong Province are mainly the results of precipitation changes. The Guangdong Province is wetter in winter, spring and autumn. Summer is coming to be drier as reflected by decreasing runoff in the season; (4) both precipitation change and water reservoirs also play important roles in the increasing of annual minimum monthly streamflow. Seasonal shifts of runoff variations may pose new challenges for the water resources management under the influences of climate changes and intensifying human activities.

    Full Text Available Introduction: Community-based models of antiretroviral therapy (ART delivery have been recommended to support ART expansion and retention in resource-limited settings. However, the evidence base for community-based models of care is limited. We describe the implementation of community-based adherence clubs (CACs at a large, public-sector facility in peri-urban Cape Town, South Africa. Methods: Starting in May 2012, stable ART patients were down-referred from the primary care community health centre (CHC to CACs. Eligibility was based on self-reported adherence, >12 months on ART and viral suppression. CACs were facilitated by four community health workers and met every eight weeks for group counselling, a brief symptom screen and distribution of pre-packed ART. The CACs met in community venues for all visits including annual blood collection and clinical consultations. CAC patients could send a patient-nominated treatment supporter (“buddy” to collect their ART at alternate CAC visits. Patient outcomes [mortality, loss to follow-up and viral rebound (>1000 copies/ml] during the first 18 months of the programme are described using Kaplan–Meier methods. Results and Discussion: From June 2012 to December 2013, 74 CACs were established, each with 25–30 patients, providing ART to 2133 patients. CAC patients were predominantly female (71% and lived within 3 km of the facility (70%. During the analysis period, 9 patients in a CAC died (<0.1%, 53 were up-referred for clinical complications (0.3% and 573 CAC patients sent a buddy to at least one CAC visit (27%. After 12 months in a CAC, 6% of patients were lost to follow-up and fewer than 2% of patients retained experienced viral rebound. Conclusions: Over a period of 18 months, a community-based model of care was rapidly implemented decentralizing more than 2000 patients in a high-prevalence, resource-limited setting. The fundamental challenge for this out of facility model was ensuring that

    Full Text Available Abstract Background Carpobrotus edulis (Mesembryanthemaceae, also known as igcukuma in Xhosa language is a medicinal plant used by the traditional healers to treat common infections in HIV/AIDS patients. Based on this information, we researched on the plant phytoconstituents, as well as its inhibitory effect using aqueous and three different organic solvent extracts in order to justify its therapeutic usage. Methods Antioxidant activity of the extracts were investigated spectrophotometrically against 1,1- diphenyl-2-picrylhydrazyl (DPPH, 2,2’-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid (ABTS diammonium salt, hydrogen peroxide (H2O2, nitric oxide (NO, and ferric reducing power, Total phenols, flavonoids, flavonols, proanthocyanidins, tannins, alkaloids and saponins were also determined using the standard methods. Results Quantitative phytochemical analysis of the four solvent extracts revealed a high percentage of phenolics (55.7 ± 0.404% in the acetone extract, with appreciable amount of proanthocyanidins (86.9 ± 0.005% and alkaloids (4.5 ± 0.057% in the aqueous extract, while tannin (48.9 ± 0.28% and saponin (4.5 ± 0.262% were major constituents of the ethanol extract. Flavonoids (0.12 ± 0.05% and flavonols (0.12 ± 0.05% were found at higher level in the hexane extract in comparison with the other extracts. The leaf extracts demonstrated strong hydrogen peroxide scavenging activity, with the exception of water and ethanol extracts. IC50 values of the aqueous and ethanolic extract against DPPH, ABTS, and NO were 0.018 and 0.016; 0.020 and 0.022; 0.05 and 0.023 mg/ml, respectively. The reducing power of the extract was found to be concentration dependent. Conclusion The inhibitory effect of the extracts on free radicals may justify the traditional use of this plant in the management of common diseases in HIV/AIDs patients in Eastern Cape Province. Overall, both aqueous and ethanol were found to be the best

    Full Text Available Background: South Africa is a source country for many destination countries that recruit registered nurses who emigrate for personal and/or professional reasons. A large number of South African nurses belong to the baby boomer generation (born between 1943 and 1964 who will retire within the foreseeable future. Statistics from the South African Nursing Council show a decline of 42.0% in the number of nurses who completed their training in South Africa from 1996 to 2005. These aspects combine to predict a potential dire shortage of nurses in South Africa within the foreseeable future.Objectives: Retention of registered nurses should be the focus of health-care planners to avoid crises in South Africa’s health-care services. This study attempted to identify factors that would influence registered nurses’ decisions to stay with their current employers in the Gauteng Province of South Africa.Methods: An exploratory descriptive quantitative design was adopted and questionnaires were sent to a sample of nurses, registered with the South African Nursing Council (SANC, with addresses in the Gauteng Province. A total of 108 nurses completed and returned questionnaires, of whom 77 (73.1% had considered leaving their current employers.Results: The most important factors that would influence more than 90.0% of these nurses’ decisions to stay with their current employers related to finances, safety and security, equipment and/or supplies, management, staff and patients.Conclusions: In terms of Maslow’s Hierarchy of Needs Theory, deficiency needs (physiological, safety and social needs should be met by improved salaries revised on an annual basis, paying long-service and outstanding-service bonuses, and improving the safety and security, as well the available equipment and supplies, at institutions. Sufficient numbers of nurses should be employed and vacancies should be filled rapidly. However, not all changes required to enhance nurses’ retention

    Full Text Available Introduction: In light of global concerns about insufficient numbers of doctors, midwives, and nurses, the World Health Organization (WHO has identified the scale-up of the production of medical professionals who are competent and responsive to community needs as urgent and necessary. Coincident with this imperative, South African medical schools have also had to consider redressing apartheid-era inequities in access to medical education and changing the racial and gender profile of medical graduates to be representative of the population. In this article, we explore progress and challenges with regard to transformation, defined as intentional and planned changes aimed at addressing historical disadvantages, in the Gauteng Province of South Africa. Methods: A cross-sectional, descriptive analysis was conducted using data on medical school admissions and graduations from the Health and Education Departments for the period 1999–2011. Admission and graduation statistics of 1999, 2005, 2008, and 2011 were analysed according to race and gender. Results: The results show that there has been progress in transforming the race and gender composition of medical students and graduates, in line with the transformation strategies of the South African government. In 1999, black African enrolments and graduates were conspicuously low in two of the three medical schools in the Gauteng province. By 2011, an almost six-fold increase in black African student enrolments was seen in one medical school that was previously designated as a white institution. In contrast, at the historically black medical school, whites only represented 0.40% of enrolments in 1999 and 7.4% in 2011. Since 1999, the number and proportion of female medical enrolments and graduates has also increased substantially. Conclusion: While there has been progress with redressing historical disparities and inequities in terms of race and gender, further efforts are needed to ensure that student

    The south-west African margin is regarded as an example of a passive continental margin formed by continental rifting following a phase of lithospheric extension and thinning. Recent attention focused on this margin has included theoretical modelling studies of rift processes, plate kinematic studies of the opening geometry and timing, and empirical studies focused on documenting the crustal structure and offshore sedimentary record. Here, we examine the onshore geomorphic and tectonic response to rifting and breakup, with a specific focus on the SW Cape of South Africa. We present 75 new apatite and 8 new zircon fission track analyses from outcrop samples and onshore borehole profiles along the western margin of South Africa. The data are used to derive robust thermal histories that record two discrete phases of accelerated erosional cooling during the Early Cretaceous (150-130 Ma) and Late Cretaceous (100-80 Ma), respectively. Both periods of enhanced erosion are regional in extent, involved km-scale erosion, and extend well inland of the current escarpment zone, albeit with spatially variable intensity and style. The Late Cretaceous episode is also expressed more locally by tectonic reactivation and inversion of major faults causing km-scale differential displacement and erosion. The new AFT data do not exclude the possibility of modest surface uplift occurring during the Cenozoic, but they restrict the depth of regional Cenozoic erosion on the western margin to less than c. 1 km. The inferred pattern and chronology of erosion onshore is consistent with the key features and sediment accumulation patterns within the offshore Orange and Bredasdorp basins. It is suggested that the Late Cretaceous event was triggered by a combination of regional dynamic uplift augmented along the western margin and in the SW Cape by local tectonic forces arising from dextral displacement of the Falkland Plateau along the Falkland-Agulhas Fracture Zone.

    A three-step methodology to assess the carbon sequestration and the environmental impact of afforestation projects in the framework of the Flexible Mechanisms of the Kyoto Protocol (Joint Implementation and Clean Development Mechanism) was developed and tested using a dataset collected from the Jonkershoek forest plantation, Western Cape, South Africa, which was established with Pinus radiata in former native fynbos vegetation and indigenous forest. The impact of a change in land use was evaluated for a multifunctional, a production and a non-conversion scenario. First, the carbon balance was modelled with GORCAM and was expressed as (1) C sequestration in tC ha{sup -1} year{sup -1} in soil, litter, and living biomass according to the rules of the first commitment period of the Kyoto Protocol, and (2) CO2 emission reductions in tC ha{sup -1} year{sup -1}, which includes carbon sequestered in the above-mentioned pools and additionally in wood products, as well as emission reductions due to fossil fuel substitution. To estimate forest growth, three data sources were used: (1) inventory data, (2) growth simulation with a process-based model, and (3) yield tables. Second, the effects of land use change were assessed for different project scenarios using a method related to Life Cycle Assessment (LCA). The method uses 17 quantitative indicators to describe the impact of project activities on water, soil, vegetation cover and biodiversity. Indicator scores were calculated by comparing indicator values with reference values, estimated for the climax vegetation. The climax vegetation is the site-specific ecosystem phase with the highest exergy content and the highest exergy flow dissipation capacity. Third, the land use impact per functional unit of 1 tC sequestered was calculated by combining the results of step 1 and step 2. The average baselines to obtain carbon additionality are 476 tC ha{sup -1} for indigenous forest and 32 tC ha{sup -1} for fynbos. Results show that

  18. Carbon sequestration and environmental effects of afforestation with Pinus radiata D. Don in the Western Cape, South Africa

    International Nuclear Information System (INIS)

    A three-step methodology to assess the carbon sequestration and the environmental impact of afforestation projects in the framework of the Flexible Mechanisms of the Kyoto Protocol (Joint Implementation and Clean Development Mechanism) was developed and tested using a dataset collected from the Jonkershoek forest plantation, Western Cape, South Africa, which was established with Pinus radiata in former native fynbos vegetation and indigenous forest. The impact of a change in land use was evaluated for a multifunctional, a production and a non-conversion scenario. First, the carbon balance was modelled with GORCAM and was expressed as (1) C sequestration in tC ha-1 year-1 in soil, litter, and living biomass according to the rules of the first commitment period of the Kyoto Protocol, and (2) CO2 emission reductions in tC ha-1 year-1, which includes carbon sequestered in the above-mentioned pools and additionally in wood products, as well as emission reductions due to fossil fuel substitution. To estimate forest growth, three data sources were used: (1) inventory data, (2) growth simulation with a process-based model, and (3) yield tables. Second, the effects of land use change were assessed for different project scenarios using a method related to Life Cycle Assessment (LCA).

    Characteristics and distribution patterns of clastic minerals (0.063~0.125 mm) in bottom sediments represent a significant indicator for the identification of the origin of sediment. One hundred and fourteen surface sediment samples, which were collected from the area near the Zhongsha Islands in the South China Sea, were analysed to identify the mineral suites and their distributions in the study area. The area can be divided into three mineral provinces: (Ⅰ) a province of biogenic minerals, which mainly originate from the Zhongsha Atoll; (Ⅱ) a province of volcanogenic minerals, which are mainly derived from local basaltic seamounts and small-scale volcanoes that are probably erupting, with some influences from the island-arc volcanic region around the South China Sea; and (Ⅲ) a mixed mineral province whose material source includes biogenic minerals, volcanogenic minerals and terrigenous minerals; the last province can be subdivided into a mixed mineral sub-province of the northeastern part of the study area, in which terrigenous minerals are mainly derived from China's Mainland and do not exceed 17°N, and a mixed mineral sub-province of the southeastern part of the study area, in which terrigenous minerals are derived from Kalimantan and Indochina Peninsula and might be further transported into the deep sea basin through submarine canyons.

    Full Text Available Postapartheid fisheries reform in South Africa, through the Marine Living Resources Act (MLRA 18 of 1998, used individual transferable quotas (ITQs to broaden resource access through allocating quotas to new entrants, even though the system has been created to reduce capacity through a reduction in the number of active fishers. The formal action space created through fisheries reform in South Africa left many artisanal fishers to operate in the informal action spaces, selling Thyrsites atun (snoek to poor communities to sustain their livelihoods. Artisanal fishers were not recognized by MLRA of 1998 and through class action case brought against the ITQ system, and in out of court settlement with the claimants in 2007, 1000 interim relief permits will be allocated to artisanal fishes and the development of a new small-scale fisheries policy for South Africa. In this case study of a fishing community in Ocean View, Cape Town I examine a snoek fishery that operates differently, through a community supply chain and informal markets, than that of the high value ITQ regulated species, yet plays a significant role in the livelihoods of artisanal fishers and in the food security of poor households. The findings of this case study show the failures of existing policy frameworks and the implications for the implementation of the new small-scale fisheries policy in South Africa.

    Full Text Available Conflict with humans poses one of the greatest threats to the persistence and survival of all wildlife. In the Cape Peninsula, South Africa, human-baboon conflict levels remain high despite substantial investment by conservation authorities in a variety of mitigation measures. Here we explore how spatial ecology can inform wildlife managers on the extent and severity of both current and projected human-baboon conflict. We apply conservative and generous densities--2.3 and 5.9 baboons/km2--to hypothetical landscape management scenarios to estimate whether the chacma baboon (Papio ursinus population in the Cape Peninsula is currently overabundant. We correlate conflict indices with spatial variables to explain intertroop differences in conflict levels. We investigate how an understanding of key elements of baboon ecology, including sleeping-site characteristics and intertroop territoriality, can direct management efforts and mitigate conflict. Our findings suggest that the current population of 475 baboons is below even the most conservative density estimate and that the area could potentially sustain up to 799 baboons. Conflict levels correlated positively with the loss of access to low-lying land through habitat transformation (Pearson r = 0.77, p = 0.015, n = 9 troops, and negatively with the distance of sleeping sites from the urban edge (Pearson r = 0.81, p = 0.001, n = 9 troops.

    Various studies have underscored the relevance of community-level factors to sexual behavior and HIV/AIDS prevention efforts in Africa. However, there is a paucity of research and theorizing in this area compared to the preponderance of prevention models that focus solely on individual-level factors. Using data from the Cape Area Panel Survey and hierarchical linear models, this study examines the effects of a combination of individual-level factors and community-level poverty on sexual behaviors. Male and female respondents who perceived themselves to be at great risk of HIV infection were less likely to indulge in risky sexual behaviors. For females, race and community-level poverty were confounded such that race mediated the effects of community-level poverty. Results from this study indicate that multiple rationalities affect sexual behaviors in Cape Town, South Africa and that there is a need to consider both the social embeddedness of sexual behaviors and the rational components of decision making when designing HIV/AIDS prevention programs.

    Full Text Available Background: There are many reports on the association between anthracosis and tuberculosis. This study focuses on bronchial anthracosis and associated diseases in the province of South Khorasan-Iran. Methods: This case-series study is performed on patients referred to the Vali-e-Asre Hospital (South Khorasan-Iran for bronchoscopic evaluations during the period of 2009-2012. Written informed consents were obtained prior to bronchoscopic evaluations. The criterion for diagnosis of bronchial anthracosis was black pigmentation on direct observation of bronchus. Bronchial anthracosis was classified into simple (without deformity or complicated (with deformity. Pulmonary tuberculosis (TB was diagnosed either by acid fast staining and culture of liquid samples, or histopathology examination of biopsy. Spirometry was performed to determine the obstructive or restrictive pattern. Results: Among 279 patients who underwent bronchoscopic evaluations, 89 patients, including 34 males (38.2% and 55 (61.79% females, were diagnosed with anthracosis. Simple and complicated anthracosis were observed in 42 (48.2% and 47 (52.8% cases respectively. Mean age of patients was 72.23±9.65 years. There were 43 (48.3% cases of tuberculosis (28 cases with complicated and 15 cases with simple anthracosis (P=0.021. Chest X-ray showed consolidation/infiltration, reticular/fibrotic, and mass/nodule/hilar prominence in 57 (64%, 26 (29.21% and 6 (6.74% cases, respectively. Bronchitis was reported in 42 (%59.15 out of 79 patients whose biopsy samples were taken. Spirometric patterns were obstructive, restrictive, upper airway obstruction, and normal in 45 (50.56%, 32 (35.95%, 2 (2.24%, and 10 (11.23% patients respectively. Conclusion: Tuberculosis is the most frequent disease associated with anthracosis in South Khorasan province. Consequently, patients with anthracosis must be carefully evaluated for tuberculosis.

    This study aimed to explore how children construct and assign meaning to the "self" within two urban communities of Cape Town in South Africa. Using a child participation methodological framework data were collected using Photovoice and community maps with 54 participants between the ages of 9 and 12. Feelings of safety, social connectedness, and children's spaces were found to be central to the ways in which the participants constructed and assigned meaning to the "self." The study provides implications for intervention programmes aimed at improving children's well-being to be inclusive of activities aimed at improving children's self-concept, including the construction of safe spaces for children to play, learn, and form meaningful relationships.

    Full Text Available Extended abstract1-IntroductionToday, one of the essential issues facing managers and planners is allocating resources to the spots which have the potentials to reserve the capital and provide the society with social and economic interests. In addition, finding a suitable spot has been the main concern of managers and planners, i.e. managers and planners, because of the resource deficiency, prefer to allocate the resources to the best places. In this regard, planners since a long time ago have tried to find out methods of choosing the best spot to centralize the industries and activities. Finding a scientific location finding method has always been a main concern of the planners. In this regard, selecting effective criteria in choosing the best spot and using suitable models to modulate data are considered as significant. In the paper, using modern methods of spotting (Hierarchical Analysis and taking economic, social aspects into account, some spots to establish markets for handicrafts in South Khorasan Province were suggested.2- Theoretical basesSimultaneously with the development of industry and its social and economic aftermaths, spotting theories to increase productivity of industrial activities and decrease their negative results and economic losses were offered. The theories have been proposed by thinkers such as: August Losch, A. Weber, Walter Isard, Greenhut, Smith, Palander, Lanhard, Christaler and Micheal Rawstron.Affected by the systemic approaches to the late 1970s issues, spotting theories had a try at concurrent modulation of two previous theories. In this approach activities and industries must be located in a way that it generates the difference between costs and incomes (profit as large as possible for the economic managers.The AHP method, as one of the most modern methods of spotting industry, made the proposed statement so easy by changing attitude, not very unexpectedly, so that it can be certainly used as the most efficient

    Full Text Available A study was taken to investigate the types of brassica vegetables mostly grown by smallholder farmers in two provinces of South Africa. Thirty-one smallholder vegetable farmers in the Gauteng province and Waterberg district in the Limpopo province were surveyed. In addition, the study also sought to establish the common diseases, the management strategies used and problems encountered by the farmers. Farmers were interviewed using a questionnaire with closed and open–ended questions. The results indicated that the smallholder farmers mostly grew cabbage (93.6% as their main brassica crop followed by rape (41.2%. Thirty percent of farmers could not identify or name the predominant disease/s encountered in their fields. Major diseases encountered by farmers surveyed were an unknown disease/s (33.3%, black rot (26.7%, Alternaria leaf spot (6.7% and white rust (6.7%. Smallholder farmers have inadequate technical information available especially relating to crop diseases, their identification and control. Farmers encountered challenges with black rot disease especially on cabbage, rape and kale and the disease was a problem during winter and summer. Generally, the smallholder farmers used crop rotation (74.2% as a major practice to manage the diseases experienced. They rotated their brassica vegetables with other crops/vegetables like tomatoes, onions, beetroots and maize. Most of the farmers interviewed (61.3% did not use chemicals to control diseases, whereas 38.7% of them used chemicals. This was mostly because they lacked information and knowledge, high costs associated with use of chemical fungicides and some were shifting towards organic farming. From the study it was noted that there was a need for technical support to improve farmers’ knowledge on disease identification and control within the surveyed areas.

    During the past three decades almost half of the existing natural tropical forests in Thailand were destroyed and replaced by cash crops, rubber, coffee, fruit orchards (durian, rambutan, mangosteen) and other commercial plantations. In order to determine the proportion of malaria cases contracted from such commercial plantations, an epidemiological study was conducted between June 1996 to May 1997 in two districts, one in Pong Nam Ron, located in a south-eastern province near the Cambodian border and another in Sai Yok, in a western province along the Myanmar border. Data were collected by passive case detection from patients attending the existing malaria clinics and active case detection by monthly malariometric survey in selected villages. All malaria cases were thoroughly investigated and classified according to exposure to different ecotypes prior to onset of malaria symptoms in the preceding two weeks. Malaria cases acquired from commercial plantations accounted for 35.2% and 11.2% in Pong Nam Ron and in Sai Yok districts respectively. In such plantations, most of the malaria cases were contracted from fruit orchards and to a lesser extent from rubber and teak plantations. From this study it is evident that commercial plantations provide a significant site of malaria transmission in addition to the forest and foothills areas in Southeast Asia where efficient vectors such as An. dirus and An. minimus are prevalent and have adapted to such changed ecosystems.

    Full Text Available Abstract Background In common with other developing countries, South Africa's public health system is characterised by human resource shortfalls. These are likely to be exacerbated by the escalating demand for HIV care and a large-scale antiretroviral therapy (ART programme. Focusing on professional nurses, the main front-line providers of primary health care in South Africa, we studied patterns of planning, recruitment, training and task allocation associated with an expanding ART programme in the districts of one province, the Free State. Methods Data collection included an audit of professional nurse posts created and filled following the introduction of the ART programme, repeated surveys of facilities providing ART over two years to assess the deployment of staff, and secondary data analysis of government personnel databases to track broader patterns of recruitment and training. Results Although a substantial number of new professional nurse posts were established for the ART programme in the Free State, nearly 80% of these posts were filled by nurses transferring from other programmes within the same facility or from facilities within the same district, rather than by new recruits. From the beginning, ART nurse posts tended to be graded at a senior level, and later, in an effort to recruit professional nurses for the ART programme, the majority (54.6% of nurses entering the programme were promoted to a senior level. The vacancy rate of nurse ART posts was significantly lower than that of other posts in the primary health care (PHC system (15.7% vs 37.1%. Nursing posts in urban ART facilities were more easily filled than those in rural areas, exacerbating existing imbalances. The shift of nurses into the ART programme was partially compensated for by the appointment of additional support staff, task shifting to community health workers, and a large investment in training of PHC workers. However, the use of less-trained, mid-level enrolled

    Cloud structure and evolution of Mesoscale Convective Systems (MCSs) retrieved from the Tropical Rainfall Measuring Mission Microwave Imager (TRMM TMI) and Precipitation Radar (PR) were investigated and compared with some pioneer studies based on soundings and models over the northern South China Sea (SCS).The impacts of Convective Available Potential Energy (CAPE) and environmental vertical wind shear on MCSs were also explored.The main features of MCSs over the SCS were captured well by both TRMM PR and TMI.However,the PR-retrieved surface rainfall in May was less than that in June,and the reverse for TMI.TRMM-retrieved rainfall amounts were generally consistent with those estimated from sounding and models.However,rainfall amounts from sounding-based and PR-based estimates were relatively higher than those retrieved from TRMM-TMI data.The Weather Research and Forecasting (WRF) modeling simulation underestimated the maximum rain rate by 22% compared to that derived from TRMM-PR,and underestimated mean rainfall by 10.4% compared to the TRMM-TMI estimate,and by 12.5% compared to the sounding-based estimate.The warm microphysical processes modeled from both the WRF and the Goddard Cumulus Ensemble (GCE) models were quite close to those based on TMI,but the ice water contents in the models were relatively less compared to that derived from TMI.The CAPE and wind shear induced by the monsoon circulation were found to play critical roles in maintaining and developing the intense convective clouds over SCS.The latent heating rate increased more than twofold during the monsoon period and provided favorable conditions for the upward transportation of energy from the ocean,giving rise to the possibility of inducing large-scale interactions.

    This study was conducted to examine the effect of urban living on smoking attitudes among black African women in South Africa. We examine how urbanicity affects attitudes toward smoking and how it moderates the relationship between both advertising exposure and network norms on black women's smoking attitudes. Respondents were 975 black women currently living in Cape Town townships, some of which were raised in rural villages or small towns. Respondents completed a cross-sectional survey, which included data on smoking attitudes, norms, and exposure to cigarette advertising. Multiple linear regression analysis was performed with smoking attitudes as the response variable, and urbanicity, cigarette advertising exposure, and network smoking norms as primary explanatory variables. Interactions were tested to determine whether urbanicity modified the effect of advertising exposure and network norms on smoking attitudes. Independent effects of urbanicity, exposure to cigarette advertising, and greater smoking prevalence within women's networks were associated with more favorable smoking attitudes. In addition, urbanicity moderated the relationship between network smoking norms and smoking attitudes, but not cigarette advertising exposure and smoking attitudes. Urbanicity, cigarette advertising, and networks play important roles in women's attitudes toward smoking, and potentially, smoking behavior. Overall, our results suggest that strong and creative anti-smoking efforts are needed to combat the potential for a smoking epidemic among an increasingly urbanized population of black women in South Africa and similar emerging markets. Additional research is warranted. PMID:18563573

    Despite the high prevalence of HIV among men who have sex with men in South Africa, very little is known about their lived realities, including their social and sexual networks. Given the influence of social network structure on sexual risk behaviours, a better understanding of the social contexts of men who have sex with men is essential for informing the design of HIV programming and messaging. This study explored social network connectivity, an understudied network attribute, examining self-reported connectivity between friends, family and sex partners. Data were collected in Cape Town and Port Elizabeth, South Africa, from 78 men who have sex with men who participated in in-depth interviews that included a social network mapping component. Five social network types emerged from the content analysis of these social network maps based on the level of connectivity between family, friends and sex partners, and ranged from disconnected to densely connected networks. The ways in which participants reported sexual risk-taking differed across the five network types, revealing diversity in social network profiles. HIV programming and messaging for this population can greatly benefit from recognising the diversity in lived realities and social connections between men who have sex with men. PMID:26569376

    Full Text Available Background: South Africa currently faces an increasing burden of cardiovascular disease. Although referred to clinics after community screening initiatives, few individuals who are identified to be at high risk for developing cardiovascular disease attend. Low health literacy and risk perception have been identified as possible causes. We investigated the knowledge and perceptions about risk for cardiovascular disease in a community.Method: We conducted a series of focus group discussions with individuals from a low incomeperi-urban community in the Western Cape, South Africa. Different methods of presenting risk were explored. The data were organised into themes and analysed to find associations between themes to provide explanations for our findings.Results: Respondents’ knowledge of cardiovascular disease and its risk factors varied, but most were familiar with the terms used to describe cardiovascular disease. In contrast, understanding of the concept of risk was poor. Risk was perceived as a binary concept and evaluation of different narrative and visual methods of presenting risk was not possible.Conclusion: Understanding cardiovascular disease and its risk factors requires a different set of skills from that needed to understand uncertainty and risk. The former requires knowledge of facts, whereas understanding of risk requires numerical and computational skills. Without a better understanding of risk, risk assessments for cardiovascular disease may fail in this community.

    Full Text Available Despite evidence from high income countries, it is not known whether screening and brief interventions (SBI for alcohol and other drug (AOD use are feasible to implement in low and middle income countries. This paper describes the feasibility and acceptability of a peer-led SBI for AOD-using patients presenting with injuries at emergency services in Cape Town, South Africa. Data were extracted from program records on the number of eligible patients screened and the number of program refusals. A questionnaire examined preliminary responses to the intervention for 30 patients who had completed the program and 10 emergency personnel. Peer counselors were also interviewed to identify barriers to implementation. Of the 1458 patients screened, 21% (305 met inclusion criteria, of which 74% (225 were enrolled in the intervention. Of the 30 patients interviewed, most (83% found the program useful. Emergency personnel were supportive of the program but felt that visibility and reach could improve. Peer counselors identified the need for better integration of the program into emergency services and for additional training and support. In conclusion, with limited additional resources, peer-led SBIs for AOD use are feasible to conduct in South African emergency services and are acceptable to patients and emergency personnel.

    Full Text Available Theoretically, co-management provides a fruitful way to engage local residents in efforts to conserve and manage particular spaces of ecological value. However, natural resource management, and biodiversity conservation in particular, are faced with novel sets of complexities in the rapidly urbanizing areas of Cape Town, South Africa, and in the nexus between an apartheid past, informal settlements, remnant biodiversity patches, and urban poverty. Departing from such a dynamic social and ecological context, this article first provides an historical account of the decade-long comanagement process at Macassar Dunes, and then considers, through stakeholder perceptions, what are the successes and failures of the contested process. We find that comanagement at Macassar Dunes faces serious legitimacy, trust, and commitment issues, but also that stakeholders find common ground on education and awareness-raising activities. In conclusion we argue that the knowledge generated from case studies like this is useful in challenging and rethinking natural resource management theory generally, but specifically it is useful for the growing cities of the Global South. More case studies and a deeper engagement are needed with geographical theories on the “urban fringe” as “possibility space”, to help build a firm empirical base for theorizing comanagement “at the fringes”, i.e., at the intersection of poverty, socioeconomic inequality, and high biodiversity and ecological values.

    2009-05-01

    The tectonic structure of the floor of the Atlantic Ocean beyond the continental margins is insufficiently studied. This is also true of its tectonic demarcation. The segmentation of the floor into regional-scale tectonic provinces of several orders proposed in this paper is primarily based on structural and historical geological features. It is shown that deep oceanic basins and fault tectonics are of particular importance in this respect. Tectonic provinces of two orders are distinguished by a set of attributes. The first-order provinces are the North, Central, South, and Antarctic domains of the Atlantic Ocean. They are separated by wide demarcation fracture zones into Transatlantic (transverse) second-order tectonic provinces. Ten such provinces are recognized (from the north southward): Greenland-Lofoten, Greenland-Scandinavia, Greenland-Ireland, Newfoundland-European, North American-African, Antilles-African, Angola-Brazil, Cape-Argentine, North Antarctic, and South Antarctic. This subdivision demonstrates significant differentiation in the geodynamic state of the oceanic lithosphere that determines nonuniform ocean formation and the tectonic features of the ocean floor. The latitudinal orientation of the second-order provinces inherits the past tectonic pattern, though newly formed structural units cannot be ruled out. The Earth rotation exerts a crucial effect on the crust and the mantle.

    Rainfed agriculture plays an important role in the agricultural production of the southern and western provinces of Iran. In rainfed agriculture, the adequacy of annual precipitation is considered as an important factor for dryland field and supplemental irrigation management. Different methods can be used for predicting the annual precipitation based on climatic and non-climatic inputs. Among which artificial neural networks (ANN) is one of these methods. The purpose of this research was to predict the annual precipitation amount (millimeters) in the west, southwest, and south of Islamic Republic of Iran with the total area of 394,259 km2, by applying non-climatic inputs according to the long-time average precipitation in each station (millimeters), 47.5 mm precipitation since the first of autumn (day), t 47.5, and other effective parameters like coordinate and altitude of the stations, by using the artificial neural networks. In order to intelligently estimate the annual amount of precipitation in the study regions (ten provinces), feedforward backpropagation artificial neural network model has been used (method I). To predict the annual precipitation amount more accurately, the region under study was divided into three sub-regions, according to the precipitation mapping, and for each sub-region, the neural networks were developed using t 47.5 and long-time average annual precipitation in each station (method II). It is concluded that neural networks did not significantly increase the prediction accuracy in the study area compared with multiple regression model proposed by other investigators. However, in case of ANN, it is better to use a structure of 2-6-6-10-1 and Levenberg-Marquardt learning algorithm and sigmoid logistic activation function for prediction of annual precipitation.

  17. What is driving CO2 emissions in a typical manufacturing center of South China? The case of Jiangsu Province

    International Nuclear Information System (INIS)

    Investigating CO2 emissions of China's manufacturing centers contributes to local and global CO2 mitigation targets. This study considers Jiangsu Province as a representation of manufacturing centers in South China. Effects of material efficiency improvements, technology development, consumption structure changes and consumption volume growth in Jiangsu Province on its CO2 emissions during 1997-2007 are investigated using structural decomposition analysis based on environmental input-output table. In order to reduce CO2 emissions, Jiangsu Province should not only rely on material efficiency improvements and technology development, but also rely on consumption structure changes. For consumption structure changes in detail, Jiangsu Province should not only focus on fixed capital formation and urban residential consumption, but also focus on international and intranational imports and exports. For the implementation of material efficiency improvements and technology development, Jiangsu Province should focus on technology innovation and international technology transfer. For the implementation of consumption structure changes, Jiangsu Province should mainly focus on identified sectors for each separate final demand category: five sectors for urban residential consumption, three sectors for fixed capital formation, four sectors for international exports, five sectors for intranational exports, three sectors for international imports and four sectors for intranational imports. - Highlights: → Effects of four factors on Jiangsu Province's CO2 emission changes are analyzed. → Key factors are identified for Jiangsu Province to achieve CO2 mitigation targets. → Key areas for consumption structure changes are analyzed. → Technology innovation and technology transfer should be concerned. → Identified sectors for each final demand category should be concerned.

    Full Text Available Mesangiocapillary glomerulonephritis (MCGN is a common cause of chronic kidney disease in developing countries. Data on the renal outcome of patients with idiopathic MCGN is limited. The aim of this study is to investigate the outcome of patients with idiopathic MCGN presenting to the Groote Schuur Hospital (GSH Renal Unit in Cape Town.A retrospective study of patients with idiopathic MCGN followed up at our clinic. Seventy-nine patients with no identifiable cause of MCGN were included for analysis. A composite renal outcome of persistent doubling of serum creatinine or end stage renal disease (ESRD was used. Kaplan Meier survival and Cox regression analysis were used to assess survival and identify factors predicting the outcome.The mean age at biopsy was 33.9±13.6 years and 41.8% were black. Mean duration of follow up was 13.5±18.8 months. Twenty-three patients (34.2% reached the composite endpoint. Overall, median renal survival was 38.7±11.7 months (95% CI 15.7-61.8 with 2-year and 5-year renal survival of 61% and 40.3% respectively. No significant difference was found for renal survival between males and females, treatment or non-treatment with immunosuppression, presence or absence of crescents or histological type of MCGN (p>0.05. On univariate Cox-regression analysis, factors found to be associated with the outcome were the estimated glomerular filtration rate at biopsy (OR 0.97 [95%CI: 0.95-0.99], p<0.0001, black race (OR 3.03 [95%CI: 1.27-7.21], p = 0.012 and presence of interstitial fibrosis in the biopsy (OR 2.64 [95%CI: 1.07-6.48], p = 0.034. Age, systolic blood pressure and attaining complete or partial remission approached significant values with the endpoint.The outcome of idiopathic MCGN in Cape Town is poor and requires further prospective studies to improve our understanding of this common disease.

    Full Text Available Abstract Background This study investigated the extent and predictors of condom use and condom refusal in the Free State province in South Africa. Methods Through a household survey conducted in the Free Sate province of South Africa, 5,837 adults were interviewed. Univariate and multivariate survey logistic regressions and classification trees (CT were used for analysing two response variables ‘ever used condom’ and ‘ever refused condom’. Results Eighty-three per cent of the respondents had ever used condoms, of which 38% always used them; 61% used them during the last sexual intercourse and 9% had ever refused to use them. The univariate logistic regression models and CT analysis indicated that a strong predictor of condom use was its perceived need. In the CT analysis, this variable was followed in importance by ‘knowledge of correct use of condom’, condom availability, young age, being single and higher education. ‘Perceived need’ for condoms did not remain significant in the multivariate analysis after controlling for other variables. The strongest predictor of condom refusal, as shown by the CT, was shame associated with condoms followed by the presence of sexual risk behaviour, knowing one’s HIV status, older age and lacking knowledge of condoms (i.e., ability to prevent sexually transmitted diseases and pregnancy, availability, correct and consistent use and existence of female condoms. In the multivariate logistic regression, age was not significant for condom refusal while affordability and perceived need were additional significant variables. Conclusions The use of complementary modelling techniques such as CT in addition to logistic regressions adds to a better understanding of condom use and refusal. Further improvement in correct and consistent use of condoms will require targeted interventions. In addition to existing social marketing campaigns, tailored approaches should focus on establishing the perceived need

    Reconstructions of Gondwana show that the Falkland Islands lie on a rotated microplate that originally lay off the Eastern Cape-Kwa-Zulu Natal (KZN) provinces of South Africa (e.g. Marshall, 1994). This implies that the Permo-Carboniferous tillites (diamictites) of South Africa and the Falklands were once contiguous. In the Western Cape, South Africa, thin tuff layers within the Dwyka Group have been precisely dated at ca 290 Ma, close to the Permian-Carboniferous boundary (Bangert et al., 19...

  12. Suitability Maps of Underground Construction in the Province of South-Holland

    Science.gov (United States)

    Herbschleb, Jurgen; Wassing, Brecht B. T.; Weerts, Henk J. T.

    Subsurface suitability maps give an insight in both the geology and the physical and chemical soil properties. The geology and soil properties together with the groundwater conditions determine technically speaking the way subsurface activities can take place. In the project described in this article a set of maps was created which indicate the suitability of the soil conditions for underground constructions. A common way to create underground constructions in the Netherlands is to use building pits and the degree of difficulty (or suitability) of underground construction is directly related to the design of the building pit. With the geological knowledge and boundary conditions that apply to the design of a building pit, a common classification of the soil properties has been made based on the type of soil (sand, clay, and peat). The combination of the strength and stiffness properties together with the thickness of the soil layers is used to obtain three suitability scores, (1) score underneath the building pit, (2) score adjacent to the pit, and (3) ground water score. These scores are added to obtain an overall suitability score. In this way, a suitability score is calculated for every site where borehole-descriptions of sufficient depth are available and groundwater conditions are known. Based on the data in the DINO-database of TNO-NITG a suitability map for subsurface building/construction was made for the province of South Holland.

    Hydatidosis is a zoonosis produced by the metacestode Echinococcus spp. The aims of this research are: to contribute to the knowledge of pediatric hydatidosis in the south-east of Buenos Aires province, to study its evolution from 1993 to 2002 at the Regional Maternity and Pediatric Hospital "Dr. Victorio Tetamanti", to determine the strains involved and to discuss the importance of the disease. The clinical records of diagnosed and/or operated patients were reviewed with regard to the hydatid disease. The strain was determined by using PCRs with Eg1 121a/122a primers. Forty-four cases were analyzed. Fifty nine point one per cent of the patients were boys. The mean age was 8 SD=3.8 years. Sixty one point four per cent had urban residence. Ultrasonography was used in 61% of the cases. The hepatic location was most frequently seen and the liver/lung ratio was 1.25. Ninety point nine per cent of patients received surgical treatment. Albendazole was used in 52% of cases. The average hospitalization time was 11 days. The G1/G2 strain group was determined. This report is the first one of its kind in the studied region. The permanence of hydatidosis in the region depends on the natural transmission of the parasite in the absence of control and prevention measures. The health authorities should implement strategies of prevention and control in the study area. PMID:19623901

    Full Text Available Scarcely 23 km from Uspallata, along the track of the old national highway 7, lies the district of Agua de la Zorra, in Mendoza province in western Argentina. Charles Darwin visited the area during his South American journeys in the 19th century and discovered a geological sequence that contained a paleoflora never described before. The flora includes an important number of species, particularly what is considered a small conifer forest with many silicified trunks still in life position. Darwin described and interpreted the sequence as sedimentary; his records show a very detailed level of observation. He also wondered about the processes that would cause the burial of the paleoflora, which he considered had happened in a marine sedimentary environment. In the modern geological framework and after a detailed study of the rocks containing the trunks, it is now interpreted that the conifer forest was buried by pyroclastic flows. Darwin accurately described the fine volcanic materials as an essential part of the deposit, but the key of the enigma about the origin of the deposits and the burial of the forest is the identification of the pyroclastic flow features; these were unknown process at the time of Darwin´s observations and interpretation.

    Full Text Available Poverty is a persistent problem in South Africa, especially among the black in the rural areas. The main objective of the study was to assess the welfare impacts of social grants among rural households in Dopeni village. The study used primary data that were collected using structured questionnaires. A representative sample of 164 rural households in Dopeni village, Limpopo Province was interviewed. Data were analyzed with FGT Poverty Index and Probit regression. The results show that using consumption expenditures, poverty line was R322. Poor households were found to be about 47%. Social grants were fairly distributed across age and gender groups. About 48.17% had salary as their source of income. Probit regression results indicated that social grants have a statistically significant positive effect on household welfare. It was recommended that information should be made available to rural people about opportunities geared to help them improve their welfare. The education curriculum should be formulated in a way that is practically applicable. Both the government and the private sector should come up with strategies to create much needed jobs.

    Introduction: To determine dietary intake of 19 to 64 years old urban Africans in Cape Town in 2009 and examine the changes between 1990 and 2009. Methods: A representative cross-sectional sample (n = 544), stratified by gender and age was randomly selected in 2009 from the same areas sampled in 1990. Socio-demographic data and a 24-h dietary recall were obtained by trained field workers. The associations of dietary data with an asset index and degree of urbanization were assessed. Results: Fat intakes were higher in 19–44-year-old men (32% energy (E)) and women (33.4%E) in 2009 compared with 1990 (men: 25.9%E, women: 27.0%E) while carbohydrate intakes were lower in 2009 (men 53.2%E, women: 55.5%E) than in 1990 (men: 61.3%E; women: 62%E) while sugar intake increased significantly (p < 0.01) in women. There were significant positive correlations between urbanization and total fat (p = 0.016), saturated fat (p = 0.001), monounsaturated fat (p = 0.002) and fat as a %E intake (p = 0.046). Urbanization was inversely associated with intake of carbohydrate %E (p < 0.001). Overall micronutrient intakes improved significantly compared with 1990. It should also be noted that energy and macronutrient intakes were all significant in a linear regression model using mean adequacy ratio (MAR) as a measure of dietary quality in 2009, as was duration of urbanization. Discussion: The higher fat and lower carbohydrate %E intakes in this population demonstrate a transition to a more urbanized diet over last two decades. These dietary changes reflect the nutrition transitions that typically occur as a longer time is spent in urban centers. PMID:27187459

    Along the southern margin of South Africa, intermountain rift successions, which comprise unusually large, rounded granite boulders and other coarse clastics, reveal an important geological history about the mid-Mesozoic extensional tectonics that lead to the break-up of Gondwana. These strata, mapped as part of the Mid to Upper Jurassic Enon Formation, allow the assessment of the nature, intensity and mode of sediment transport in onshore section of the Pletmos Basin, which is one of the late Mesozoic basins in southern Africa. Based on sedimentary facies analysis, palaeocurrent measurements and semi-quantitative palaeohydraulic calculations, the results suggest that the abundant coarse sediment was deposited by debris-flows and stream-flow floods on a proximal alluvial fan with high gradient alluvial channels. The floods were intense with mean flow velocity of ∼6 m3/s and peak discharge of ∼450 m3/s. While the role of climate in the sedimentation dynamics remains unknown, syn-sedimentary rift tectonics were likely significant and caused, north of the major boundary fault, the unroofing and denudation of the uplifted mountainous source areas, including the Late Ediacaran-Cambrian Maalgaten Granite Suite and the Siluro-Ordovician Table Mountain Group (Cape Supergroup).

    With the implementation of the South African National Water Act (NWA) currently underway, water intensive sectors, such as the irrigated agriculture sector, can expect reduced water allocations and an increase in water prices. Water footprints (WFs) are increasingly being recognised as a meaningful way by which to represent human appropriation of water resources. This study examines the green and blue WFs of a variety of citrus cultivars in the lower Sundays River Valley, Eastern Cape, South Africa. WFs were calculated across dry, humid and long-term average climates and comparisons were made to available global average benchmark WFs. An number of indicators were also explored including; water productivity (ton/m3), economic land productivity (R/ha) and economic water productivity (R/m3) across all three climatic years. Most applications of WF sustainability assessments have focused on examining physical water scarcity as a measure for determining environmental hotspots. This study, therefore, also calculates the marginal product value for the irrigation water using a non-parametric linear programming approach. Marginal product value of irrigation water is not only useful in assisting with water-allocation decision making, but also useful in demonstrating the effects of resource depletion and degradation, and is therefore a useful measure for determining economic water scarcity. The study highlights that both farmers and governments could reduce blue WF's through adopting measures to increase water efficiency and considering economic water and land productivity. It also demonstrates the importance of including both environmental and economic scarcity indicators into water management and planning strategies, and the importance of conducting WF assessments using more accurate, site specific data.

    Full Text Available Few studies have investigated the interplay of multiple factors affecting the prevalence of tuberculosis in developing countries. The compositional and contextual factors that affect health and disease patterns must be fully understood to successfully control tuberculosis. Experience with tuberculosis in South Africa was examined at the household level (overcrowding, a leaky roof, social capital, unemployment, income and at the neighbourhood level (Gini coefficient of inequality, unemployment rate, headcount poverty rate. A hierarchical random-effects model was used to assess household-level and neighbourhood-level effects on self-reported tuberculosis experience. Every tenth household in each of the 20 Rhini neighbourhoods was selected for inclusion in the sample. Eligible respondents were at least 18 years of age and had been residents of Rhini for at least six months of the previous year. A Kish grid was used to select one respondent from each targeted household, to ensure that all eligible persons in the household stood an equal chance of being included in the survey. We included 1020 households within 20 neighbourhoods of Rhini, a suburb of Grahamstown in the Eastern Cape, South Africa. About one-third of respondents (n=329; 32% reported that there had been a tuberculosis case within the household. Analyses revealed that overcrowding (P≤0.05 and roof leakage (P≤ 0.05 contributed significantly to the probability of a household TB experience, whereas higher social capital (P≤0.01 significantly reduced this probability. Overcrowding, roof leakage and the social environment affected tuberculosis prevalence in this economically disadvantaged community. Policy makers should consider the possible benefits of programs that deal with housing and social environments when addressing the spread of tuberculosis in economically poor districts.

    Full Text Available Skin lesions associated with papillomaviruses have been reported in many animal species and man. Bovine papillomavirus (BVP affects mainly the epidermis, but also the dermis in several species including bovine, the best-known example being equine sarcoid, which is associated with BVP types 1 and 2. This publication describes and illustrates the macroscopic and histological appearance of BPV-associated papillomatous, fibropapillomatous or sarcoid-like lesions in Cape mountain zebra (Equus zebra zebra from the Gariep Dam Nature Reserve, 2 giraffes (Giraffa camelopardalis from the Kruger National Park, and a sable antelope (Hippotragus niger from the Kimberley area of South Africa. An African buffalo (Syncerus caffer cow from Kruger National Park also had papillomatous lesions but molecular characterisation of lesional virus was not done. Immunohistochemical staining using polyclonal rabbit antiserum to chemically disrupted BPV-1, which cross-reacts with the L1 capsid of most known papillomaviruses, was positive in cells of the stratum granulosum of lesions in Giraffe 1, the sable and the buffalo and negative in those of the zebra and Giraffe 2. Fibropapillomatous and sarcoid-like lesions from an adult bovine were used as positive control for the immunohistochemistry and are described and the immunohistochemistry illustrated for comparison. Macroscopically, both adult female giraffe had severely thickened multifocal to coalescing nodular and occasionally ulcerated lesions of the head, neck and trunk with local poorly-circumscribed invasion into the subcutis. Necropsy performed on the 2nd giraffe revealed neither internal metastases nor serious underlying disease. Giraffe 1 had scattered, and Giraffe 2 numerous, large, anaplastic, at times indistinctly multinucleated dermal fibroblasts with bizarre nuclei within the sarcoid-like lesions, which were BPV-1 positive in Giraffe 1 and BPV-1 and -2 positive in Giraffe 2 by RT-PCR.

    Introduction: Adolescents having unprotected heterosexual intercourse are at risk of HIV infection and unwanted pregnancy. However, there is little evidence to indicate whether pregnancy in early adolescence increases the risk of subsequent HIV infection. In this paper, we tested the hypothesis that adolescent pregnancy (aged 15 or younger) increases the risk of incident HIV infection in young South African women. Methods: We assessed 1099 HIV-negative women, aged 15–26 years, who were volunt...

    Full Text Available Background: In South Africa cervical cancer is the second most commonly occurring cancer amongst women, and black African women have the highest risk of developing this disease. Unfortunately, the majority of South African women do not adhere to recommended regular cervical screening.Objectives: The purpose of this research was to explore the perceptions, experiences and knowledge regarding cervical screening of disadvantaged women in two informal settlements in South African urban areas.Method: The Health Belief Model (HBM provided a theoretical framework for this study. Four focus groups (n = 21 were conducted, using questions derived from the HBM, and thematic analysis was used to analyse the data. The ages of the women who participated ranged from 21 to 53 years.Results: The analysis revealed lack of knowledge about screening as a key structural barrier to treatment. Other structural barriers were: time, age at which free screening is available, and health education. The psychosocial barriers that were identified included: fear of the screening procedure and of the stigmatisation in attending screening. The presence of physical symptoms, the perception that screening provides symptom relief, HIV status, and the desire to know one’s physical health status were identified as facilitators of cervical screening adherence.Conclusion: This knowledge has the potential to inform healthcare policy and services in South Africa. As globalisation persists and individuals continue to immigrate or seek refugee status in foreign countries, increased understanding and knowledge is required for successful acculturation and integration. Developed countries may therefore also benefit from research findings in developing countries.

  8. Irrigation Management Transfer and WUAs' dynamics: evidence from the South-Kazakhstan province

    The importance of water resources management in the arid and semi-arid lands can not be overestimated being related with environmental, economical and socio-political issues. In Central Asia, due to the physical and climatic features, water control and irrigation have always played a strategic role in territorial and societal development. Since the collapse of the Soviet Union in Kazakhstan, as in the other Central Asian republics, significant changes in both the water and agricultural sector have emerged; water management shifted from a purely technical issue to a sociopolitical and economic one leading to several institutional and organizational changes. To address this transitional water management context and the related governance and technical issues, since the 1990s several development organizations and donor agencies (such as the World Bank, United Nations, USAID, and others), according to the international water community, have sought to streamline the Irrigation Management Transfer (IMT) and the establishment of the Water Users Associations (WUAs); this initiatives are sponsored and related to the IWRM framework, the water program globally supported by the Global Water Partnership and widely debated and questioned in the last years. This paper aims to discuss these transitional water management processes focusing on the meso-local level in the Arys valley, administratively included in the South-Kazakhstan province, ten years since the enactment of the law formalizing the WUAs. Three districts (Tyulkibas, Ordabasy and Otrar) were selected to analyse and understand the specific local transitional water institutional/organizational framework and to highlight the differences among them. The fieldwork was conducted in two different phases, April-May and November-December 2012. Within those periods, semi-structured interviews were carried out to the members of the state organizations (river basin agencies and district/province water departments) as well as the

    Full Text Available Abstract Background Crucial connections between sexual network structure and the distribution of HIV remain inadequately understood, especially in regard to the role of concurrency and age disparity in relationships, and how these network characteristics correlate with each other and other risk factors. Social desirability bias and inaccurate recall are obstacles to obtaining valid, detailed information about sexual behaviour and relationship histories. Therefore, this study aims to use novel research methods in order to determine whether HIV status is associated with age-disparity and sexual connectedness as well as establish the primary behavioural and socio-demographic predictors of the egocentric and community sexual network structures. Method/Design We will conduct a cross-sectional survey that uses a questionnaire exploring one-year sexual histories, with a focus on timing and age disparity of relationships, as well as other risk factors such as unprotected intercourse and the use of alcohol and recreational drugs. The questionnaire will be administered in a safe and confidential mobile interview space, using audio computer-assisted self-interview (ACASI technology on touch screen computers. The ACASI features a choice of languages and visual feedback of temporal information. The survey will be administered in three peri-urban disadvantaged communities in the greater Cape Town area with a high burden of HIV. The study communities participated in a previous TB/HIV study, from which HIV test results will be anonymously linked to the survey dataset. Statistical analyses of the data will include descriptive statistics, linear mixed-effects models for the inter- and intra-subject variability in the age difference between sexual partners, survival analysis for correlated event times to model concurrency patterns, and logistic regression for association of HIV status with age disparity and sexual connectedness. Discussion This study design is

  10. High prevalence of tuberculosis and insufficient case detection in two communities in the Western Cape, South Africa.

    Directory of Open Access Journals (Sweden)

    Mareli Claassens

    Full Text Available BACKGROUND: In South Africa the estimated incidence of all forms of tuberculosis (TB for 2008 was 960/100000. It was reported that all South Africans lived in districts with Directly Observed Therapy, Short-course. However, the 2011 WHO report indicated South Africa as the only country in the world where the TB incidence is still rising. AIMS: To report the results of a TB prevalence survey and to determine the speed of TB case detection in the study communities. METHODS: In 2005 a TB prevalence survey was done to inform the sample size calculation for the ZAMSTAR (Zambia South Africa TB and AIDS Reduction trial. It was a cluster survey with clustering by enumeration area; all households were visited within enumeration areas and informed consent obtained from eligible adults. A questionnaire was completed and a sputum sample collected from each adult. Samples were inoculated on both liquid mycobacterium growth indicator tube (MGIT and Löwenstein-Jensen media. A follow-up HIV prevalence survey was done in 2007. RESULTS: In Community A, the adjusted prevalence of culture positive TB was 32/1000 (95%CI 25-41/1000 and of smear positive TB 8/1000 (95%CI 5-13/1000. In Community B, the adjusted prevalence of culture positive TB was 24/1000 (95%CI 17-32/1000 and of smear positive TB 9/1000 (95%CI 6-15/1000. In Community A the patient diagnostic rate was 0.38/person-year while in community B it was 0.30/person-year. In both communities the adjusted HIV prevalence was 25% (19-30%. DISCUSSION: In both communities a higher TB prevalence than national estimates and a low patient diagnostic rate was calculated, suggesting that cases are not detected at a sufficient rate to interrupt transmission. These findings may contribute to the rising TB incidence in South Africa. The TB epidemic should therefore be addressed rapidly and effectively, especially in the presence of the concurrently high HIV prevalence.

    Early Jurassic bimodal volcanic and intrusive rocks in southern South China show distinct associations and distribution patterns in comparison with those of the Middle Jurassic and Cretaceous rocks in the area. It is widely accepted that these rocks formed in an extensional setting, although the timing of the onset and the tectonic driver for extension are debated. Here, we present systematic LA-ICP-MS zircon U-Pb ages, whole-rock geochemistry and Sr-Nd isotope data for bimodal volcanic rocks from the Changpu Formation in the Changpu-Baimianshi and Dongkeng-Linjiang basins in southern Jiangxi Province, South China. Zircon U-Pb ages indicate that the bimodal volcanic rocks erupted at ca. 190 Ma, contemporaneous with the Fankeng basalts (~ 183 Ma). A compilation of geochronological results demonstrates that basin-scale basaltic eruptions occurred during the Early Jurassic within a relatively short interval (South China.

    Full Text Available Accidental injury due to burns is a serious and common, but preventable, occurrence in children. To analyze the characteristics of pediatric burns in the south of Liaoning province of China, a retrospective review was conducted of information, including general characteristics, demographics, etiology of burns, anatomical areas burned, and severity of injuries, obtained from medical records of pediatric burn patients admitted to the Burn Center of Anshan Hospital of the First Hospital of China Medical University from 2002 to 2011. Differences between age-groups and cause and severity of injuries were examined using Cochran-Mantel-Haenzsel ­(C-M-H statistic or chi-square (χ2 analyses where appropriate. A total of 985 pediatric burn cases were included, with only one death. The maximal burn area recorded was 80% and the maximal third-degree burn area was 45%. The majority of burns (637/985, 64.67% were moderate second-degree wounds, encompassing 5-14% of the total body surface area. The infant age-group (<3 years old had the largest representation (622/985, 63.15%, with more males than females affected. Most of the injuries occurred at home in children living in the local region. Scalding accounted for 89.85% (885/985 of all injuries, with a decreasing incidence with age, whereas injuries due to flames and from electrical sources markedly increased with age. Only a minority of guardians (244/985, 24.77% had burn prevention knowledge, and none of them knew how to provide first-aid treatment for burn injuries. These results indicate that the majority of pediatric burns occur in children less than 3 years of age from scalds received while at home. As a large proportion of these cases occurred in rural areas, programs emphasizing burn prevention and treatment knowledge should therefore be made more available to these families.

  14. Low-temperature thermochronology of the Mt Painter Province, South Australia

    International Nuclear Information System (INIS)

    Apatite fission track results are reported for 26 outcrop samples from the Mt Painter Inlier, Mt Babbage Inlier and adjacent Neoproterozoic rocks of the northwestern Curnamona Craton of South Australia. Forward modelling of the data indicates that the province experienced variable regional cooling from temperatures >110deg C during the Late Palaeozoic (Late Carboniferous to Early Permian). The timing of this cooling is similar to that previously reported from elsewhere in the Adelaide Fold Belt and the Curnamona Craton, suggesting that the entire region underwent extensive Late Palaeozoic cooling most likely related to the waning stages of the Alice Springs or Kanimblan Orogenies. Results from the Paralana Fault Zone indicate that the eastern margin of the Mt Painter Inlier experienced a second episode of cooling (∼40-60deg C) during the Paleocene to Eocene. The entire region also experienced significant cooling (less than ∼40deg C) during the Late Cretaceous to Palaeogene in response to unroofing and/or a decrease in geothermal gradient. Regional cooling/erosion during this time is supported by: geomorphological and geophysical evidence indicating Tertiary exhumation of at least 1 km; Eocene sedimentation initiated in basins adjacent to the Flinders and Mt Lofty Ranges sections of the Adelaide Fold Belt; and Late Cretaceous - Early Tertiary cooling previously reported from apatite fission track studies in the Willyama Inliers and the southern Adelaide Fold Belt. Late Cretaceous to Palaeogene cooling is probably related to a change in stress field propagated throughout the Australian Plate, and driven by the initiation of sea-floor spreading in the Tasman Sea in the Late Cretaceous and the Eocene global plate reorganisation.

    Full Text Available Land redistribution was legislated in 1994; it was designed to resolve historical imbalances inland ownership in South Africa. Between 2002 and 2006, a longitudinal observational studywas conducted with 15 purposively selected small-scale dairy farmers in a land redistributionproject in Central North West Province. Four farmers left the project over the period. For thepurposes of this study, a small-scale dairy farm was defined as a farm that produces less than500 L of milk a day, irrespective of the number of cows or size of the farm. The study wasconducted in three phases. In the first phase, situational analysis using participatory ruralappraisal (PRA and observation was used to outline the extent of the constraints and designappropriate interventions. Feeds that were used were tested and evaluated. In the secondphase, three different feeding systems were designed from the data obtained from PRA. Thesewere: (1 A semi-intensive farm-based ration using available crops, pastures and crop residueswith minimal rations purchased. (2 An intensive, zero-grazing dairy system using a totalmixed ration. (3 A traditional, extensive or dual-purpose system, where the calf drank fromthe cow until weaning and milking was done only once a day. In the third phase, adoptionwas monitored. By July 2006, all remaining farmers had changed to commercially formulatedrations or licks and the body condition score of the cows had improved. It was concluded thatveterinary extension based on PRA and a holistic systems approach was a good option forsuch complex problems. Mentoring by commercial dairy farmers, veterinary and extensionservices appeared to be viable. Further research should be done to optimise the traditionalmodel of dairy farming, as this was relatively profitable, had a lower risk and was less labourintensive.

Patients and Methods: A cross-sectional study was carried out in Khuzestan, South west Iran, from October to December, 2012. Randomly selected participants were placed in two groups: Rice farmers as cases, and non-farmers as controls. Blood samples obtained from the participants were tested for IgM anti-leptospira antibodies using Serion ELISA classic ESR 125M. The assays were performed and interpreted according to the manufacturer’s instructions. A questionnaire including variables related to Leptospira spp. exposure was administered to each participant. SPSS software version 16 was employed; Chi square and Fisher’s exact tests were used to analyze data. Results: Of the total 288 samples, 65 (22.5%) were positive for IgM anti-leptospira antibodies. Among the positive samples, 52 (36.1%) were from the case (rice farmer) and 14 (9.7%) from the control groups. There was a significant difference between the case and control groups regarding leptospiral infection (P 0.05). In the case group, males and those more than 35 years were at a higher risk of infection. Conclusions: Rice farmers are significantly infected with leptospirosis, and infection prevalence is highly affected by gender (male) and age (above 35 years). Rice farming parts of Khuzestan, Iran may be considered as endemic for leptospirosis. PMID:25368799

    Full Text Available Job satisfaction is an attitude that employees have about their work and is based on numerous factors, both intrinsic and extrinsic to the individual. Job satisfaction is important from the perspective of maintaining and retaining the appropriate employees within the organization, it is about fitting the right person to the right job in the right culture and keeping them satisfied. Job satisfaction at salesforce level has become a topic of growing concern since significant proportion of marketing budgets, especially in harmaceutical industry of South Africa, is spent on them to achieve the assigned targets in the circular market. Although a large number of studies have been conducted to investigate job satisfaction in diverse range of the cultures, subjects and occupations yet none has attempted to explore the impact of job content and context factors on the job satisfaction among pharmaceutical salespersons in South Africa. Thus, the current study intends to determine the variance in salespersons’ overall job satisfaction through job content and context factors as a whole. This study also extends the total repercussion on the sales persons and their satisfaction level that cement the good will of the company and personal upliftment.

    Results of a survey and study of the Claviceps purpurea group of species in South Africa are being presented and five new species are described. Morphological descriptions are based on the anamorphs and four nuclear genetic loci. Claviceps fimbristylidis sp. nov. on Fimbristylis complanata was discovered wide-spread across five provinces of the country associated with water and represents the fourth Claviceps species recorded from the Cyperaceae. Claviceps monticola sp. nov. is described from Brachypodium flexum growing in mountain forests in Mpumalanga Province, as well as the northern Drakensberg southwards into the Eastern Cape Province. Claviceps pazoutovae sp. nov. is recorded from Stipa dregeana var. dregeana and Ehrharta erecta var. erecta, also associated with these mountain ranges. Claviceps macroura sp. nov. is recorded from Cenchrus macrourus from the Eastern Cape and Claviceps capensis sp. nov. from Ehrharta villosa var. villosa is recorded from the Western Cape Province. Claviceps cyperi, only recorded from South Africa is included in the study. Ergot alkaloid profiles of all species are provided and showed similarity to C. purpurea. Only C. cyperi and in lesser degree C. capensis, C. macroura, and C. pazoutovae produced ergot alkaloids in clinically significant amounts. Several reported species infect invasive grass species, native to South Africa, and thus represent potentially invasive species. PMID:27521625

    Full Text Available This article describes the researchers’ efforts to apply the principles of Participatory Action Research (PAR, specifically participation, through the direct involvement of church members in the research. It includes involving them in the design of questionnaires, training and utilizing them as fieldworkers, and finally disseminating the results of the research via workshops aimed at strategizing for change. The research is based on two hypotheses, the first being that, churches and their members are intensely involved in serving both the needs of their own members, as well as the needs of the larger community; and secondly, that churches do not work alone, but are part of networks with other agencies to accomplish their goals. At the outset the article outlines the challenges and points of departure, followed by a chronological account of how this approach was applied in Paarl, a South African community. Finally, an overview of the results of the project is provided.

    Full Text Available Abstract Background Antiretroviral therapy (ART dramatically improves outcomes for children in Africa; however excellent adherence is required for treatment success. This study describes the utility of different measures of adherence in detecting lapses in infants and young children in Cape Town, South Africa. Methods In a prospective cohort of 122 HIV-infected children commenced on ART, adherence was measured monthly during the first year of treatment by medication return (MR for both syrups and tablets/capsules. A questionnaire was administered to caregivers after 3 months of treatment to assess experience with giving medication and self-reported adherence. Viral and immune response to treatment were assessed at the end of one year and associations with measured adherence determined. Results Medication was returned for 115/122 (94% children with median age (IQR of 37 (16 – 61 months. Ninety-one (79% children achieved annual average MR adherence ≥ 90%. This was an important covariate associated with viral suppression after adjustment for disease severity (OR = 5.5 [95%CI: 0.8–35.6], p = 0.075, however was not associated with immunological response to ART. By 3 months on ART, 13 (10% children had deceased and 11 (10% were lost to follow-up. Questionnaires were completed by 87/98 (90% of caregivers of those who remained in care. Sensitivity of poor reported adherence (missing ≥ 1 dose in the previous 3 days for MR adherence Conclusion Excellent adherence to ART is possible in African infants and young children and the relatively simple low technology measure of adherence by MR strongly predicts viral response. Better socio-economic status and more palatable regimens are associated with better adherence.

    Stynder, Deano D.

    2009-01-01

    The dietary regimes of 15 ungulate species from the middle Pleistocene levels of the hominid-bearing locality of Elandsfontein, South Africa, are investigated using the mesowear technique. Previous studies, using taxonomic analogy, classified twelve of the studied species as grazers ( Redunca arundinum, Hippotragus gigas, Hippotragus leucophaeus, Antidorcas recki, Homoiceras antiquus, Damaliscus aff. lunatus, Connochaetes gnou laticornutus, Rabaticerus arambourgi, Damaliscus niro, Damaliscus sp. nov., an unnamed "spiral horn" antelope and Equus capensis), one as a mixed feeder ( Taurotragus oryx) and two as browsers ( Tragelaphus strepsiceros and Raphicerus melanotis). Although results from mesowear analysis sustain previous dietary classifications in the majority of cases, five species were reclassified. Three species previously classified as grazers, were reclassified as mixed feeders ( H. gigas, D. aff. lunatus and R. arambourgi), one previously classified as a grazer, was reclassified as a browser (the "spiral horn" antelope), and one previously classified as a mixed feeder, was reclassified as a browser ( T. oryx). While current results broadly support previous reconstructions of the Elandsfontein middle Pleistocene environment as one which included a substantial C 3 grassy component, the reclassifications suggest that trees, broad-leaved bush and fynbos were probably more prominent than what was previously thought.

  9. Communication training for centre-based carers of children with severe or profound disabilities in the Western Cape, South Africa

    2012-05-01

    Full Text Available The purpose of this paper is to provide a preliminary, qualitative review of an approach to training centre-based carers in supporting basic communication development and providing communication opportunities for the children with severe and profound disabilities in their care. In South Africa, these children are often the most neglected in terms of planning and providing appropriate interventions. For those with severe communication disabilities, an additional lack is in the area of the basic human right to meaningful interactions and communication. Sustainable strategies to provide opportunities for basic communication development of these children are urgently sought. Several effective international and local parent training programmes have been developed, but the urgent need remains to train centre-based carers who are taking care of groups of diversely disabled children in severely under-resourced settings. Non-profit organisations (NPOs have been exploring practical centre-based approaches to skills sharing in physical rehabilitation, activities for daily living, feeding and support for basic communication development. As a freelance speech therapist contracted by four NPOs to implement hands-on training in basic communication for centre-based carers of non-verbal children, the author describes a training approach that evolved over three years, in collaboration with the carers and centre managements. Implications for training (for speech therapists and for community-based rehabilitation workers and for further research are identified.

    This study examined gender attitudes and sexual violence-supportive beliefs (rape myths) in a sample of South African men and women at risk for HIV transmission. Over 40% of women and 16% of men had been sexually assaulted, and more than one in five men openly admitted to having perpetrated sexual assault. Traditional attitudes toward women's social and gender roles, as well as rape myths, were endorsed by a significant minority of both men and women. Multivariate analyses showed that for men, sexual assault history and rape myth acceptance, along with alcohol and other drug use history, were significantly related to cumulative risks for HIV infection. In contrast, although we found that women were at substantial risk for sexually transmitted infection (STI), including HIV, women's risks were only related to lower levels of education and alcohol use history. We speculate that women's risks for STI/HIV are the product of partner characteristics and male-dominated relationships, suggesting the critical importance of intervening with men to reduce women's risks for sexual assault and STI/HIV.

    In the antiretroviral era, youth perinatally infected with HIV (PHIV+) are surviving into adulthood and are at risk for emotional and behavioural problems. Few studies of these problems have been conducted in low- and middle-income countries and even fewer in sub-Saharan Africa. The aims of this study were to provide a quantitative description of emotional and behavioural problems in a group of PHIV+ youth (n = 78) in South Africa compared with a group of demographically matched HIV-negative controls (n = 30) and to identify correlates of emotional and behavioural problems. A cross-sectional study was conducted employing participants from community and hospital-based clinics. Emotional and behavioural problems were assessed using the Child Behaviour Checklist (CBCL). Several measures were used to assess demographic, biological, cognitive and contextual correlates of problem behaviours. Youth were compared by HIV status on demographic, cognitive and contextual variables as well as the Total Problems and subscale scores of the CBCL. Multivariate comparisons of the influence of contextual and cognitive variables on CBCL Total Problems scores were performed using a stepwise linear regression analytic procedure. In this study, there were no significant differences in between-group comparisons for the prevalence of Internalizing, Externalizing and Total Problems in the PHIV+ youth and control group at the clinical and borderline cut-off ranges of the CBCL. Caregiver depression was the only significant predictor of greater Total Problems scores in the full model, after controlling for age and gender (F = 8.57, df = 5.102, P < .01). An interaction between HIV status and caregiver depression was observed (t = -2.20, P = .03), with follow-up within-group analyses confirming that caregiver depression predicted greater Total Problems scores both in HIV-negative youth (β = 0.61, P < .001), and to a lesser extent, in HIV-positive youth (

    Full Text Available A serological survey of leptospirosis in cattle originating from rural communities of the province of KwaZulu-Natal (KZN in South Africa was carried out between March 2001 and December 2003. The survey was designed as a 2-stage survey, using the local dip tank as the primary sampling point. In total, 2021 animals from 379 dip tanks in 33 magisterial districts were sampled and tested with the microscopic agglutination test (MAT. The apparent prevalence at district level was adjusted for clustering and diagnostic test sensitivity and specificity and displayed in maps. The prevalence of leptospirosis in cattle originating from communal grazing areas of KZN was found to be 19.4% with a 95% confidence interval of 14.8-24.1 %. At district level the prevalence of leptospirosis varied from 0 to 63 % of cattle. Bovine leptospirosis was found to occur in communal grazing areas throughout the province with the exception of 2 districts. The southeastern regions showed a higher prevalence than other areas of the province; while in some of the northern and western districts a lower prevalence was noted. Several serovars were detected by the MAT and although Leptospira interrogans serovar pomona occurred most frequently, serovars tarrasovi, bratislava, hardjo, canicola and icterohaemorrhagica were also frequently identified. The findings of the survey are discussed.

  4. Levels of brominated flame retardants and other pesistent organic pollutants in breast milk samples from Limpopo province, South Africa

    International Nuclear Information System (INIS)

    The non-occupational exposure to brominated flame retardants, and other persistent organic pollutants (POPs) was studied by collecting human breast milk samples from mothers residing in Thohoyandou area, a rural district in the Limpopo Province, northern part of South Africa (SA). Of all collected samples to be analysed (n = 28), those with large enough milk volumes, (n = 14) were quantified for polybrominated diphenyl ethers (PBDEs) (9 congeners: BDE-28, 47, 66, 99, 100, 138, 153, 154, and 183) and hexabromocyclododecane (HBCD) on a GC equipped with dual capillary columns and dual electron-capture detectors (ECD). The levels of PBDE congeners (median sumBDE 1.3 ng/g of lipids) and of HBCD were not far from levels generally found in European studies, and this study may be the first report on the presence of PBDEs and HBCD in SA breast milk. On a congener basis, the finding of comparably high BDE-183 levels suggests a specific PBDE usage, or contamination situation in SA. Apart from BFRs, the high DDT levels found in the breast milk from this area (median and maximum sumDDT levels of about 4 600 and over 20 000 ng/g of lipids, respectively; n = 28) have earlier been reported. In addition, other POPs (PCBs, HCB and HCHs) were found in SA breast milk, at relatively low levels. To conclude, measurable levels of PBDEs and HBCD, and a specific BDE congener pattern, were found in breast milk from the Limpopo province, SA. A number of other POPs, including DDTs in high levels, were also present. - Highlights: → Persistent organic pollutants (POPs) were analysed in South African breast milk. → Focus of interest were brominated flame retardants (BRFs). → Sampling area was the rural Limpopo Province, northern SA. → Probably the first reported African data on BFRs (PBDEs, HBCD) in breast milk. → Reported BFR data similar to European levels.

    Access to sustainable water and sanitation services is one of the biggest challenges the developing world faces as an increasing number of people inhabit those areas. Inadequate access to water and sanitation infrastructure often leads children to drink poor quality water which can result in early childhood diarrhea (ECD). Repeated episodes of ECD can cause serious problems such as growth stunting, cognitive impairment, and even death. Although researchers have long studied the connection between poor access to water and hygiene facilities and ECD, most studies have relied on intervention-control methods to study the effects of singular interventions. Such studies are time-consuming, costly, and fail to acknowledge that the causes and prevention strategies for ECD are numerous and complex. An alternate approach is to think of a community as a complex system in which the engineered, natural and social environments interact in ways that are not easily predicted. Such complex systems have no central or coordinating mechanism and may exhibit emergent behavior which can be counterintuitive and lead to valuable insights. The goal of this research is to develop a robust, quantitative understanding of the complex pathogen transmission chain that leads to ECD. To realize this goal, we have developed an Agent-Based Model (ABM) which simulates individual community member behavior. We have validated this transdisciplinary model with four years of field data from a community in Limpopo Province, South Africa. Our model incorporates data such as household water source preferences, collection habits, household- and source-water quality, water-source reliability and biological regrowth. Our outcome measures are household water quality, ECD incidences, and child growth stunting. This technique allows us to test hypotheses on the computer. Future researchers can implement promising interventions with our partner institution, the University of Venda, and the model can be refined as

    The Dutch East India Company (VOC) intended the Cape of Good Hope to be a refreshment stop for ships travelling between the Netherlands and its eastern colonies. The indigenous Khoisan, however, did not constitute an adequate workforce, therefore the VOC imported slaves from East Africa, Madagascar and Asia to expand the workforce. Cape Town became a cosmopolitan settlement with different categories of people, amongst them a non-European underclass that consisted of slaves, exiles, convicts and free-blacks. This study integrated new strontium isotope data with carbon and nitrogen isotope results from an 18th-19th century burial ground at Cobern Street, Cape Town, to identify non-European forced migrants to the Cape. The aim of the study was to elucidate individual mobility patterns, the age at which the forced migration took place and, if possible, geographical provenance. Using three proxies, 87Sr/86Sr, δ13Cdentine and the presence of dental modifications, a majority (54.5%) of the individuals were found to be born non-locally. In addition, the 87Sr/86Sr data suggested that the non-locally born men came from more diverse geographic origins than the migrant women. Possible provenances were suggested for two individuals. These results contribute to an improved understanding of the dynamics of slave trading in the Indian Ocean world. PMID:27309532

    Full Text Available Abstract Background Much communicable disease control research has had little impact on local control programme policy and practice for want of an operational component. The operational research model – the systematic search for knowledge on interventions, tools or strategies that enhance programme effectiveness – is gaining recognition as an appropriate method for addressing perplexing questions within public health programmes. Methods A series of operational research studies were conducted to refine malaria diagnosis in Mpumalanga Province, South Africa between 1995 and 1999. The grounded theory approach was used with groups of experienced Masters of Public Health students in South Africa and Australia to analyse a compilation of these studies for determining positive and negative attributes of operational research that affect its ability to influence communicable disease control policy and practice. Results The principal positive attributes of the operational research studies were high local relevance, greater ability to convince local decision-makers, relatively short lag-time before implementation of findings, and the cost-effective nature of this form of research. Potential negative features elicited included opportunities forfeited by using scarce resources to conduct research and the need to adequately train local health staff in research methodology to ensure valid results and accurate interpretation of findings. Conclusions Operational research effectively influenced disease control policy and practice in rural South Africa, by providing relevant answers to local questions and engaging policy-makers. This resulted in accelerated inclusion of appropriate measures into a local communicable disease control programme.

  13. A geological and hydrogeochemical investigation of the uranium potential of an area between the Orange and Kuruman Rivers, northwestern Cape Province. V.1

    International Nuclear Information System (INIS)

    An extensive geological, hydrological and hydrochemical study was conducted to determine the uranium potential of an area which includes the greater part of the Gordonia District and part of the bordering Kuruman District. The area is situated between 21 and 22 degrees east, the Kuruman River in the north and the Orange River in the south. All berohole information germane to the area, such as Government and private drill records have been studied. As a result of this study maps of the area have been compiled, showing surface and pre-Karoo geology, the pre-Karoo and pre-Kalahari topography and the thickness of the Karoo and post-Karoo cover. Contour maps of water levels were compiled from which a regional east-west flow pattern was deduced, indicating a large groundwater basin which could be divided into four smaller basins. Hydrochemical studies substantiate the inferred flow pattern of the groundwater. Of prime importance in this investigation was the study of the distribution of uranium in the groundwater of the area and its association with the various lithologies encountered. Radiometric borehole logging of all accessible boreholes in the most promising areas delineated by this study confirmed the presence of uranium mineralisation in the depositional basins (in particular the Dwyka Tillite Formation) west of the granite-gneiss ridge. Uranium mineralisation in surficial deposits was also discovered as a result of the reassessment of radiometric airborne data obtained previously. It is concluded that potential economic uranium deposits may exist in the Dwyka Tillite Formation northwest of Upington and in the surficial diatomaceous earth deposits on the farm Rus-en-Vrede

    This study reports on the water quality index (WQI) of wastewater and drinking water in the Mpumalanga and North West provinces of South Africa. The WQI is one of the most effective tools available to water sustainability researchers, because it provides an easily intelligible ranking of water quality on a rating scale from 0 to 100, based on the ascription of different weightings to several different parameters. In this study the WQI index ratings of wastewater and drinking water samples were computed according to the levels of pH, electrical conductivity (EC), biochemical oxygen demand (BOD), E. coli, temperature, turbidity and nutrients (nitrogen and phosphates) found in water samples collected from the two provinces between June and December, 2014. This study isolated three groups of WQ-rated waters, namely: fair (with a WQI range = 32.87-38.54%), medium (with a WQI range = 56.54-69.77%) and good (with a WQI range = 71.69-81.63%). More specifically, 23%, 23% and 54% of the sampled sites registered waters with fair, medium and good WQ ratings respectively. None of the sites sampled during the entire period of the project registered excellent or very good water quality ratings, which would ordinarily indicate that no treatment is required to make it fit for human consumption. Nevertheless, the results obtained by the Eerstehoek and Schoemansville water treatment plants in Mpumalanga and North West provinces, respectively, suggest that substantial improvement in the quality of water samples is possible, since the WQI values for all of the treated samples were higher than those for raw water. Presence of high levels of BOD, low levels of dissolved oxygen (DO), E. coli, nitrates and phosphates especially in raw water samples greatly affected their overall WQ ratings. It is recommended that a point-of-use system should be introduced to treat water intended for domestic purposes in the clean-water-deprived areas.

    The NE-trended Mesozoic granodioritic intrusions are spatially and temporally associated with the copper multi-metal mineralization in southeastern Hunan Province, South China. U-Pb dating result of single-grained zircons of four samples respectively from Shuikoushan, Baoshan, western Tongshanling and eastern Tongshanling intrusions reveals that their crystallization age spans a range from 172 Ma to 181 Ma, which also represents the oldest age of the regional copper multi-metal mineralization. Some of the zircon grains give an upper intercept age of about 1753 Ma and 207Pb/206Pb apparent age of (1752 ± 4) Ma, implying the involvement of the pre-Cambrian metamorphic (possible Middle Proterozoic) basement in their genesis. The presence of such a kind of zircon grains in these granodiorites indicates either that the parental magmas were assimilated by basement rocks during magma ascent or that lower/middle crustal rocks were one of the important components during the melting process.

    Full Text Available A total of 344 dogs belonging to people in resource-poor communities in North West Province, South Africa, was examined for ectoparasites, and all visible arthropods were collected from the left side of each dog. By doubling these numbers it was estimated that the dogs harboured 14 724 ixodid ticks, belonging to 6 species, 1028 fleas, belonging to 2 species, and 26 lice. Haemaphysalis leachi accounted for 420 and Rhipicephalus sanguineus for 14 226 of the ticks. Pure infestations of H. leachi were present on 14 dogs and of R. sanguineus on 172 dogs. Small numbers of Amblyomma hebraeum, R. appendiculatus, R. evertsi evertsi and R. simus were also collected. The predominance of R. sanguineus accounts for the high prevalence of canine ehrlichiosis (Ehrlichia canis within the survey region, compared to canine babesiosis (Babesia canis, which is transmitted by H. leachi, and is a much rarer disease.

    Full Text Available Early Triassic (Griesbachian to Spathian ostracod faunas are here first discovered and described form the Guangxi Province, South China. Thirty-seven species belonging to fourteen genera are recognized. Seven species are new: Bairdia fengshanensis n.sp., Bairdia wailiensis n.sp., Liuzhinia guangxiensis n.sp., Ptychobairdia luciaae n.sp., Ptychobairdia aldaae n.sp., Paracypris jinyaensis n.sp. and Paracypris gaetanii n.sp. The Griesbachian assemblage from the basal microbial limestone is well diversified and does not suggest any abnormal palaeoenvironmental conditions in terms of salinity, temperature or oxygen content. Particularly, the ostracods are typical of well oxygenated water and do not reflect any anoxia. Dienerian and Smithian ostracods are evidenced for the first time and the assemblages suggest less favourable palaeoenviromental conditions. Diversity and abundance of ostracod assemblages recovered from the Spathian on. The main taxonomic turnover among ostracod assemblages occurred seemingly between the Griesbachian and the Spathian.

    Full Text Available Ticks were collected at approximately bi-monthly intervals between June 1996 and June 1997 from crested francolins, Francolinus sephaena, and from the vegetation on a mixed cattle and wildlife farm in Limpopo Province, South Africa. The birds were infested with the immature stages of 13 tick species, of which Amblyomma hebraeum, Amblyomma marmoreum and Hyalomma marginatumrufipes were the most numerous and prevalent. Ten ixodid tick species were collected from the vegetation, of which the immature stages of Rhipicephalus appendiculatus, Rhipicephalus (Boophilus decoloratus and Rhipicephalus evertsi evertsi were the most numerous. No adult ticks were collected from the birds and only two from the vegetation. The restricted home range of crested francolins implies that they could serve as a source of tick infestation only for other animals within the same habitat as the birds.

    The current study focussed on documenting the ethnobotanical knowledge of herbal medicines used by the Bapedi traditional healers to treat reproductive ailments in the Limpopo Province, South Africa. Fifty one healers from 17 municipalities covering Capricorn, Sekhukhune and Waterberg districts of the Limpopo Province were interviewed between January and July 2011. Semi-structured interviews, observations and guided field surveys with the healers were employed. Thirty-six medicinal plant species belonging to 35 genera and 20 families were documented. The most used species were Zanthoxylum humile (25.5%), Catha edulis (21.6%), Ozoroa sphaerocarpa (15.7%), Hypoxis hemerocallidea (13.7%), Hypoxis obtusa (11.7%), Gomphocarpus fruticosus subsp. fruticosus and Gymnosporia senegalensis (9.8% each). The dominant growth forms among the reported medicinal plants were herbs (39%), followed by shrubs and trees with 33% and 28%, respectively. The preferred plant parts were roots (63.9%), followed by bark (13.9%), whole plant (11.1%), tubers (8.3%), bulbs (5.6%), fruits, leaves, stems and twigs (2.8% each). The majority of the species were used to treat gender specific reproductive ailments; while a minority were used for treating reproductive ailments of both genders. Twenty-two species (61.1%) are supported by reports of similar uses in other countries or have proven biological activity. This study illustrates that Bapedi traditional healers possess remarkable knowledge on medicinal plants used for treating and managing reproductive ailments. PMID:24146458

    2009-09-01

    Full Text Available Alcohol abuse is a problem in South Africa and it has negative effects on the wellbeing of individuals, families, friends, work associates and neighbours. Alcohol produces both psychological and physical dependence. Gillies (1999:112 indicated that alcoholism usually interferes with the ability to socialize, work and may lead to much other destructive behaviour. It was further stated that people who are addicted to alcohol often have a low self-esteem, immaturity, are easily frustrated, and have difficulty in solving personal problems. This study investigated the perceptions of community members towards youth abusing alcohol and identified, among others, anti-social behaviour, poor interpersonal relationships, family disorganization, poor integration with family members and physical damage as the major concerns. An attempt was also made to develop strategies that can be used to overcome the problems of alcohol abuse by youth. Design and Method: A qualitative, exploratory, descriptive and contextual research design was followed in this study for the participants to describe their perceptions regarding the phenomenon in question (Brink, 2006:113. Data were collected through individual unstructured interviews in one village of the Capricorn District of the Limpopo Province. The researchers employed the principles of Guba and Lincoln (1993 cited in De Vos (1998:331 relating to trustworthiness and adhered to the ethical standards as set by the Democratic Nurses Association of South Africa (DENOSA, 1998:2.3.2.Findings: Five themes and seven categories emerged from the data analysis, using Tech’s open coding approach (1990, as outlined in De Vos (1998:343, namely, antisocial behaviour, poor interpersonal behaviour, physical damage, poor progress in life processes and effects of alcohol on the body.

    Stratigraphic analyses document climatic and tectonic controls on the filling of a Late Triassic to early Middle Jurassic (T3-J2) basin that developed on top of a young orogenic belt in southeastern South China. About 2700 m of Carnian to Bajocian sedimentary rocks is documented in the Meizhou region, Guangdong Province. The Carnian to Rhaetian sequence is characterized by deltaic facies that are succeeded by Hettangian fluvial, shallow marine and volcaniclastic facies, and by Sinemurian to early Toarcian interdistributary bay and floodplain facies. The late Toarcian to Bajocian sequence comprises proximal alluvial to lacustrine facies that changed upwards to fluvial facies. Fossil assemblages indicate that climatic conditions changed from tropical/subtropical warm humid, to temperate humid, and then to hot arid through the Late Triassic to the Middle Jurassic. Climatically induced changes (e.g., in precipitation, vegetation and erosion) exerted a strong influence on sediment supply, whereas tectonics played a dominant role in stratigraphic evolution, accommodation generation, sedimentation pattern and volcanism. Tectonostratigraphic analysis shows that the T3-J2 basin was initiated on an orogenic belt during late-stage orogeny, and evolved into shallow-marine and volcanic environments and then back to terrestrial facies during the post-orogenic stage. This was followed by regional uplift and the development of a basin-and-range province. The order of these events is similar to that of the central Rocky Mountains, western North America during the Palaeogene. The Mesozoic basin of South China and the Eocene basins of the central Rocky Mountains highlight the importance of subduction-related subsidence above young and broad orogens.

    Full Text Available It is shown that there is a wide range of structural variation in the habit of the Arundineae and Ehrharteae of the fynbos of the Cape Floristic Region (Cape Province, South Africa. Structural differences in the bases of the fynbos grasses have been classified into four groups: swollen, knotty tillering, weak and annual. Variation in the position of the innovation buds occurs with one group having basal perennating buds, implying that all the culm material is annual, while the second group has cauline innovation buds, leading to the development of a divaricate perennial herb. The recognition of caducous, mesic (orthophyllous and sclerophyllous leaf blades is also possible, based on leaf morphology and anatomy. These variations in growth forms allow the classification of the Cape grasses into five guilds adapted for survival in the dense fynbos vegetation that develops between the well-spaced fires in these heathlands. The following guilds have been recognized: competition avoiders that grow on rock ledges and outcrops where competition from shrubby vegetation is reduced; reseeders, that survive the protracted interfire period as seed; geophytes, that survive this period as underground organs; coppicers, that survive as small plants; and competitors, that grow tall by means of cauline innovation buds, and so are able to compete with the shrubby heath vegetation.

    Optimized allocation of water resources is the important means of solving regional water shortage and can improve the utilization of water resources. Water resources allocation in the large-scale water diversion project area is the current research focus. This research takes the east route of the South-to-North Water Transfer Project in Jiangsu province as the research area, based on the hydrological model, agricultural irrigation quota model, and water project scheduling model, a water resources allocation model was constructed. The research carried on generalized regional water supply network, simulated the water supply, water demand and water deficit in agriculture, industry, life, ecology and lock under the status quo and planning engineering conditions. According to the results, the east route of the South-to-North Water Transfer Project is helpful to improve regional water shortage situation. The results showed that pump output increase by 2.8 billion cubic meters of water. On the conditions of P = 95%, 75% and 50%, compared with the benchmark year, water demand increases slightly due to the need of social and economic development in planning years, and water supply increased significantly because of new diversion ability. Water deficit are greatly reduced by 74.9% especially in the commonly drought condition because of the new project operation and optimized allocation of water resources.

    This study aimed to assess the prevalence of depressed symptoms and associated factors in prenatal HIV-positive women in primary care facilities in rural South Africa. In a cross-sectional study, 663 HIV-positive prenatal women in 12 community health centres in Mpumalanga province, South Africa, were recruited by systematic sampling (every consecutive patient after HIV post-test counselling). Results indicate that overall, 48.7% [95% CI: 44.8, 52.6] of women during the prenatal period reported depressed mood (scores of ≥ 13 on the Edinburgh Postnatal Depression Scale 10). In multivariate analysis, not being employed, unplanned pregnancy, not having an HIV-positive child, poor antiretroviral therapy adherence, non-condom use at last sex, and intimate partner violence were associated with depressive symptoms. Potential risk factors among HIV-infected prenatal women were identified which could be utilized in interventions. Routine screening for depression may be integrated into prenatal care settings.

    Full Text Available Background: South Africa is on the brink of another wave of major health system reforms that underscore the centrality of primary health care (PHC. Nursing managers will play a critical role in these reforms. Objective: The aim of the study was to explore the work experiences of PHC clinic nursing managers through the use of reflective diaries, a method hitherto under-utilised in health systems research in low- and middle-income countries. Design: During 2012, a sub-set of 22 PHC nursing managers was selected randomly from a larger nurses’ survey in two South African provinces. After informed consent, participants were requested to keep individual diaries for a period of 6 weeks, using a clear set of diary entry guidelines. Reminders consisted of weekly short message service reminders and telephone calls. Diary entries were analysed using thematic content analysis. A diary feedback meeting was held with all the participants to validate the findings. Results: Fifteen diaries were received, representing a 68% response rate. The majority of respondents (14/15 were female, each with between 5 and 15 years of nursing experience. Most participants made their diary entries at home. Diaries proved to be cathartic for individual nursing managers. Although inter-related and not mutually exclusive, the main themes that emerged from the diary analysis were health system deficiencies; human resource challenges; unsupportive management environment; leadership and governance; and the emotional impact of clinic management. Conclusions: Diaries are an innovative method of capturing the work experiences of managers at the PHC level, as they allow for confidentiality and anonymity, often not possible with other qualitative research methods. The expressed concerns of nursing managers must be addressed to ensure the success of South Africa's health sector reforms, particularly at the PHC level.

  20. Volcanic and granite type uranium metallogenesis of South China uranium metallogenic province

    International Nuclear Information System (INIS)

    Uranium deposits of both volcanic and granite type are studied as the systematic process of tectonic evolution-magmatism-metallogenic fluid action in South China. By summarizing the geological characteristics of hydrothermal uranium deposits, the spatial-temporal distribution of regional uranium mineralization and hydrogen and oxygen isotopic compositions of ore-forming fluid are used to study the origin of ore-forming matter and to elaborate its evolution and metallogenic process. It is considered that Early Cambrian uranium-rich strata are the most substantial uranium sources for hydrothermal uranium deposit in South China and the ore-forming fluid is the mixture of magmatic water and meteoric water. Uranium was accumulated by magmatism controlled by Yanshanian tectonic extension or transitional geodynamic background which facilitated the formation and evolution of ore-forming hydrothermal systems and metallogenesis.

    Psittacine beak and feather disease (PBFD), the most prevalent viral disease affecting psittacines, is caused by beak and feather disease virus (BFDV). This study assessed viral load using qPCR in a wild Cape parrot population affected by PBFD and compared it to overall physical condition based on clinical signs attributable to PBFD. A significant inverse correlation between viral load and overall physical condition was found, which confirmed that clinical signs may confidently be used to diagnose the relative severity of BFDV infections in wild populations. This is the first assessment of BFDV viral load in a wild psittacine population. PMID:25193072

  8. Radio-ecological problems of the South Kazakhstan in connection with uranium deposits of Shu-Sarysuy and Syrdarya provinces

    International Nuclear Information System (INIS)

    The South Kazakhstan is a region of the Republic with most alarming epidemiological situation. Almost all medical indicators of health condition of inhabitants including children are much lower than the average statistical one for the Republic in whole. One of the main reasons for high morbidity level of the South Kazakhstan inhabitants, undoubtedly, is a critical point of ecological and radio-ecological situation in this region. There are some mechanisms that formed this situation. One of them is the intensive agricultural activity with use of chemical (phosphor, potassium, nitric) fertilizers. The next mechanism is the pollution of the environment and waters with industrial and domestic wastes and effluents of large cities. The most important and least studied feature for this region is presence of considerable reserves of natural uranium (20-30 % of world reserves) and long-lived, intensive industrial activity on its mining and processing. According to geological character the deposits of Shu-Sarysuy and Syrdarya uranium-ore provinces, generally, belong to deposits of bedded-infiltration type in low-lithified sediment rocks. The ore substances of these deposits are allocated in regional fronts of the zones of bedded oxidation on the horizon of chalk and Palaeocene. Along these fronts a vast aureole of bedded waters were formed with anomalous concentrations of radionuclides, especially, of 226Ra (up to 50 Bq/l) and uranium (up to 150 μg/1). Besides, a vast outlet of carbonaceous-siliceous shale characterized by 'hurricane' contents of rare and dispersed elements such as V, Cr, Co, As, Se, Hg, Th, and U is observed at the sides of the mountain range Karatau. Mining process was prevented by great bore-hole exploring works over several ten years. The provinces are located in the range of artesian basins. In this connection, water well-spring occurred at many bore-holes (as a result of crippling of locking device). This mass uncontrolled process leads to intensive

    Full Text Available Background: South Africa is one of the countries in the world with a high burden of tuberculosis (TB. High rates of unfavourable treatment outcomes have remained a feature of TB control in the country. The objective of the current study was to examine the treatment outcomes of TB among health care workers (HCWs at a rural general hospital in the Mpumalanga province of the country, as well as the clinical care that was provided to the HCWs. The purpose of the study was to identify possible areas for improvement in the TB care services provided to HCWs in the hospital, especially with regard to their clinical management.Method: The research described in this article consists of a retrospective descriptive study. Relevant data on HCWs diagnosed with TB in the hospital during 2007, the TB care services offered to the HCWs, and the treatment outcomes of the HCWs were captured from the occupational health and TB control programme registers at the hospital onto a data capture sheet for the study and were subsequently analysed manually.Results: Nine HCWs, eight females and one male, were diagnosed and treated for TB in the hospital during 2007, an incidence rate of 941/100 000. Their ages ranged from 39 to 54 years, with a mean age of 48 years. By occupation, the nine HCWs consisted of six nurses (67%, one porter (11%, one general assistant (11%, and one clerk (11%. Of those treated for TB, seven (78% had smearpositive pulmonary TB (PTB and two (22% had extra-pulmonary TB (EPTB. TB culture and drug susceptibility testing (DST was undertaken for only one HCW. The HIV status was known for only two (22% of the nine HCWs under review. Neither of the two HCWs with EPTB had the diagnosis confirmed by bacteriological or histopathological method. The seven HCWs with smear- positive PTB achieved a cure, and the two HCWs with EPTB successfully completed treatment, resulting in a treatment success rate of 100% for the nine HCWs.Conclusion: The HCWs at Themba

  10. Panorama from 'Cape Verde'

    2007-01-01

    NASA's Mars Exploration Rover Opportunity captured this vista of 'Victoria Crater' from the viewpoint of 'Cape Verde,' one of the promontories that are part of the scalloped rim of the crater. Opportunity drove onto Cape Verde shortly after arriving at the rim of Victoria in September 2006. The view combines hundreds of exposures taken by the rover's panoramic camera (Pancam). The camera began taking the component images during Opportunity's 970th Martian day, or sol, on Mars (Oct. 16, 2006). Work on the panorama continued through the solar conjunction period, when Mars was nearly behind the sun from Earth's perspective and communications were minimized. Acquisition of images for this panorama was completed on Opportunity's 991st sol (Nov. 7, 2006). The top of Cape Verde is in the immediate foreground at the center of the image. To the left and right are two of the more gradually sloped bays that alternate with the cliff-faced capes or promontories around the rim of the crater. 'Duck Bay,' where Opportunity first reached the rim, is to the right. Beyond Duck Bay counterclockwise around the rim, the next promontory is 'Cabo Frio,' about 150 meters (500 feet) from the rover. On the left side of the panorama is 'Cape St. Mary,' the next promontory clockwise from Cape Verde and about 40 meters (130 feet) from the rover. The vantage point atop Cape Verde offered a good view of the rock layers in the cliff face of Cape St. Mary, which is about 15 meters or 50 feet tall. By about two weeks after the Pancam finished collecting the images for this panorama, Opportunity had driven to Cape St. Mary and was photographing Cape Verde's rock layers. The far side of the crater lies about 800 meters (half a mile) away, toward the southeast. This approximately true-color view combines images taken through three of the Pancam's filters, admitting light with wavelengths centered at 750 nanometers (near infrared), 530 nanometers (green) and 430 nanometers (violet).

    The aim of this study was to assess the epidemiological characteristics of a representative sample of subsidized low-cost housing communities in the City of Cape Town in relation to their living conditions and their health status. Four subsidized low-cost housing communities were selected within the City of Cape Town in this cross-sectional survey. Structured interviews were administered in 336 dwellings on 173 plots. Data was obtained from 1,080 persons with a response rate of 100%. Almost all of the state-subsidized houses had one or more shacks in the backyard, increasing the occupation density and putting the municipal sanitation infrastructure under pressure. In 40% of main houses, one or more cases of diarrhea were reported during the two weeks preceding the survey, in contrast to 23% of shacks (p cost housing in this study. The health vulnerability of individuals in these communities had considerable implications for the curative health services. Sanitation failures, infectious disease pressure, and environmental pollution in these communities represent a serious public health risk. The densification caused by backyard shacks, in addition, has municipal service implications and needs to be better managed. Urgent intervention is needed to allow the state-funded housing schemes to deliver the improved health that was envisaged at its inception. PMID:21108010

    A Late Pleistocene-Holocene pollen, phosphorus, and charcoal record was reconstructed from apeatland in southern Jiangxi Province in southern China. The area today has a mountainous and rolling landscape with villages, small towns, and agriculture dominated by rice paddies, vegetable, and fruit gardens, as well as areas of secondary forest and pine re-afforestation. The record opens before 14 300 yr BP, with Alnus woodland dominating the wetland areas and with an open Quercus woodland on the surrounding slopes.The forest area becomes more complex from approximately 12 800 yr BP and further from 9 000 yr BP. At approximately 6 000 yr BP, there is evidence of clearing and, by 4 500-4 000 yr BP, a complete collapse in the wetland Alnus and terrestrial forest as the low-lying areas are converted to rice production. For much of the record, the occurrence of fire around the site was low, although there is evidence of regional fires. Fire was used as a tool in clearing and then used in the annual cycles of stubble burning after rice harvest. Nutrient levels, as reflected by total phosphorus in the sediment, seem to be closely related to forest changes and high values in the surface layers probably result from land-management techniques associated with agriculture. Therefore, human impact greatly altered forest cover, fire frequency, and nutrient dynamics; this has been evident for approximately 6 000 yr BP and then intensifies towards the present day.

    A new species and 2 new records of lichen genus Buellia were discovered from Chuja-do Island in Jeju Province during a recent floristic survey: B. chujana X. Y. Wang, S. Y. Kondr., L. Lőkös & J.-S. Hur sp. nov., B. halonia (Ach.) Tuck., and B. mamillana (Tuck.) W. A. Weber. The new species is characterized by a brown, areolate thallus, the presence of perlatolic acid, and a saxicolous habitat. Together with previously recorded species, 10 Buellia species were confirmed from Jeju-do Island. Among these species, 3 growing in the exposed rocky area contained xanthone (yellowish lichen thallus, UV + orange), indicating that production of xanthone in this genus might be a defense strategy against the harm of UV light. Although the genus Buellia has been thoroughly studied in Korea before, novel species have been discovered continuously, and large species diversity has been found in this crustose genus, even from a small rocky island. This study indicates that the coastal area harbors a vast number of crustose lichen species, and there is great potential to discover unknown lichens in the coastal rocky area in Korea.

    Late Pliocene to Early Pleistocene (~ 3.25-2.05 Ma), 200-400 m thick basalt lavas outcrop in the South Caucasus region, including the Kars-Erzurum Plateau (northeastern Turkey), the Javakheti Plateau (Georgia-Armenia), and the Lori Plateau (northern Armenia). These fissure-fed, rapidly erupted fluid lavas filled pre-existing river valleys over many tens of kilometres. The basalts exposed in the Debed River canyon, northern Armenia, are ~ 200 m thick and of three morphological types: (1) basal pillow basalts and hyaloclastites, overlain by (2) columnar-jointed pahoehoe sheet flows, in turn overlain by (3) slabby pahoehoe and rubbly pahoehoe flows. The lower and middle lavas show evidence for damming of river drainage, like many lavas of the Columbia River flood basalt province, Scotland, Ireland, and Iceland. There is also evidence for syn-volcanic faulting of the early lavas. Related basalts also outcrop in the Gegham Uplands and the Hrazdan River basin in Armenia. This 3.25-2.05 Ma South Caucasus basalt province, covering parts of Turkey, Georgia and Armenia, has an estimated areal extent of ~ 15,000 km2 and volume of ~ 2250 km3. Because its main geological features are remarkably like those of many continental flood basalt (CFB) provinces, we consider it a true, albeit small, CFB province. It is the smallest and youngest CFB in the world. An analogue closely similar in major features is the Late Miocene Altos de Jalisco CFB province in the western Trans-Mexican Volcanic Belt. Both provinces formed during lithospheric pull-apart and transtensional faulting. Their broader significance is in showing flood basalt size distribution to be a continuum without natural breaks, with implications for geodynamic models.

    Full Text Available Aim: To determine the prevalence and causes of visual impairment, cataract surgical coverage and barriers to cataract surgery amongst people in the northern eThekwini district of KwaZuluNatal Province, South Africa.Method: Thirty-three clusters of 50 subjects ≥ 50 years old were randomly selected. Consenting subjects underwent enumeration to establish a demographic profile and thereafter a clinical examination. Visual acuity (VA was measured with a Tumbling ‘E’ chart; participants having a VA < 6/18 were retested with a pinhole. If no improvement in VA occurred, subjects underwent clinical examination, including a dilated fundus exam where necessary, to determine the cause of visual impairment.Results: Of the 1650 subjects selected, 1542 (93.5% were examined. The overall prevalence of blindness was 1.9%. The age- and gender-adjusted prevalence of blindness was 2.1%, severe visual impairment (SVI 1.2%, and moderate visual impairment (MVI 3.9%. Untreated cataract was the major cause of blindness (55.2% and SVI (53.3%, and uncorrected refractive error was the major cause of MVI (49.1%. The cataract surgical coverage rate was 70% at visual acuity < 3/60 level; 51% at visual acuity < 6/60 level; and 38% at visual acuity < 6/18 level. Poor awareness of cataract surgical intervention was the main reason that participants with untreated cataracts had not used existing cataract services.Conclusion: The prevalence of blindness in the study region was lower (by 1.98% than World Health Organization estimates of 9% for the Africa-E sub-region (within which South Africa falls. There is no permanent cataract service in this region; the lower cataract surgical coverage rates indicate that a permanent eye care centre could significantly alleviate avoidable blindness, particularly that caused by cataract.

  18. Geochemistry of early mesozoic potassium-rich diorites-granodiorites in southeastern Hunan Province, South China. Petrogenesis and tectonic implications

    International Nuclear Information System (INIS)

    The diorites-granodiorites emplaced at ca. 175 Ma in southeastern Hunan tectonic-magmatic belt (SHB), South China Block (SCB), are high-K calc-alkaline. They are characterized by LREE-LILE enrichment and HFSE depletion with slight or no Eu anomalies. Age-corrected initial 87Sr/86Sr ratio spans a narrow range of 0.707962-0.710396 and εNd(t) of -6.98--2.30. These features are significantly different from those of the neighboring other Mesozoic granitic plutons (Eu/Eu* = 0.30-0.70; 87Sr/86Sr > 0.710; εNd = -12 to -16) in South China, which have been interpreted as the remelting products of Precambrian basement. The crust anatexis cannot account for the geochemical characteristics of these diorites-granodiorites in the SHB. The partial melting of an enriched lithosphere mantle directly produced mafic-intermediate rather than acid magma, and can also not explain the geochemical and isotopic variations exhibited by these diorites-granodiorites. These diorites-granodiorites likely represent partial melting products of mantle-derived basaltic rocks, which were underplated and hybridized with old crust material at lower/middle crust level. Theoretical modeling further suggests that this hybridized source consisted of 15-30% of the lower/middle crust and 70-85% of depleted mantle-drived basaltic rocks. The occurrence of these diorite-granodiorites in southeastern Human province therefore marked a major intra-lithospheric extension episode during early Mesozoic. (author)

    The Lower Cambrian black shales of the Niutitang Formation and their lateral equivalents occur widely on the Yangtze Platform, South China. In this study, we examine two sections of the Niutitang Formation in Guizhou Province. We employ a stepwise acid-leaching technique to obtain Pb-isotope compositions of the black shales. At the Zhongnan section, the black shales display large Pb isotope variations, with 206Pb/204Pb of 20.5396~33.5709, and 207Pb/204Pb of 15.8407~16.5782. In contrast, Pb isotope data show a relatively limited range in 206Pb/204Pb (18.2797~18.5972) and 207Pb/204Pb (15.6813~15.7159) at the Zhijin section. Data for all acid-leached black shale samples from the two sections yield a Pb-Pb isochron age of 531±24 Ma. This age may represent the sedimentary age of the black shales. The initial Pb-isotope composition of the black shales falls near the upper-crust evolution curve in a Zartman Pb-Pb evolution diagram. Hence, it is likely that the Pb in the black shales may have been derived from an upper continental crustal source.

  12. The link between interannual variation of the South China Sea summer monsoon onset and summer precipitation in Shandong Province

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    Relationship between the onset date of South China Sea (SCS) summer monsoon and the summer rainfall in Shandong Province was examined by comprehensive analysis to establish a conceptual model of the link. If the summer monsoon occurs earlier, the 500 hPa level would induce the teleconnection of Eurasian pattern in the summer (June-August), which indicates that the western Pacific subtropical high is displaced northward further than usual, the Siberian high is intensified and the Okhotsk low is deepened. Under such circumstance, Shandong, located in the west side of the subtropical high and in front of the mid-Siberia high, would be expected to have a wet summer because it is quite possible for cold and warm air to meet and interact with each other in Shandong. Statistical analysis revealed that the 500 hPa anomalies over Korea and Japan were sensitive to the SCS monsoon onset date and very important to precipitation in Shandong, and that the convective activities over the deep water basin in the SCS in 24-26 pentads significantly influenced the position of the ridge lineof the western Pacific subtropical high. These findings yielded better understanding of the causative mechanisms involved in the precipitation generation, so that the knowledge gained can possibly be applied for long-lead forecast.

    Because of the abundant geological, geochemical and geophysical studies conducted on the Emeishan large igneous province (ELIP) in South China, the Permian mantle plume model associated with this region is widely accepted. Furthermore, the dome-shaped structure related with this plume has been determined with success by sedimentological data and gravity stripping. Although the sediment thickness, upper crust, Moho depth and the lithosphere-asthenosphere boundary (LAB) are well constrained by active- and passive-source seismological results, the density anomaly in ELIP is still a poorly constrained issue that needs further attention. With the aim especially to understand the impact on surface of the magmatic processes that originated in the deep mantle, we performed the COMGRA-ELIP gravity experiment across this region. Using a stripping method, we determined the residual gravity in ELIP and surrounding areas. The residual gravity reaches a maximum value of + 150 mGal in the inner zone of ELIP and its strength decreases gradually when measuring from the inner zone to the middle and outer zones. Combining active and passive seismic results and the least-squares variance analysis method, we propose a strong density contrast of 0.2 g/cm3 (density of 3.14 g/cm3) for the 15- to 20-km-thick igneous layer accreted at the base of the crust, as evidence of crustal underplating in ELIP, to explain the present-day residual gravity anomaly.

    Radiological hazards associated with exposure to Naturally Occurring Radionuclides Materials from gold mine tailings in the province of Gauteng in South Africa were evaluated. A comparison was made with soil samples from a control area. In this study, gamma spectroscopy was used to measure the activity concentrations of these radionuclides in 56 soil samples from the mine tailings and 10 soil samples from the control area. The average activity concentrations in Bq∙kg(-1) for Uranium-238, Thorium-232, and Potassium-40 from the mine tailings were found to be 785.3 ± 13.7, 43.9 ± 1.0 and 427.0 ± 13.1, respectively. On the other hand, the average activity concentrations in Bq∙kg(-1) for Uranium-238, Thorium-232, and Potassium-40 from the control area were found to be 17.0.1 ± 0.4, 22.2 ± 0.5 and 496.8 ± 15.2, respectively. Radiological hazard parameters calculated from these activity concentrations were higher than recommended safe limits. In particular, calculated average values for the external hazard (Hex) and the internal hazard (Hin) from the mine tailings were found to be 2.4 and 4.5. Both these values were higher than unity, posing a significant health risk to the population in the area. PMID:26797624

    The geographic concentration of chronic sleep deprivation (CSD) remains largely unexplored. This paper examined the community-specific spatial pattern of the prevalence of CSD and the presence of clustered spatial hotspots among the Korean elderly population in Gyeongbuk Province, South Korea, revealing CSD hotspots and underscoring the importance of geography-focused prevention strategies. The study analysed cross-sectional data collected from 9847 elderly individuals aged 60 years and older who participated in a Korean Community Health Survey conducted in 2012. To assess the level of spatial dependence, an exploratory spatial data analysis was conducted using Global Moran's I statistic and the local indicator of spatial association. The results revealed marked geographic variations in CSD prevalence ranging from 33.4 to 73.4%, with higher values in the metropolitan urban areas and lower in the rural areas. Almost half of the community residents [both men (44.1%) and women (53.5%)] slept 6 h or less per 24 h. The average CSD prevalence (53.6% men and 65.1% women) in the hotspots was about 13.0% higher than that in other areas (42.6% for men and 51.1% for women). To our knowledge, this is the first study to generate a CSD hotspot map that includes data on sleep deprivation across metropolitan district levels. This study demonstrates that not only is sleep deprivation distributed differentially across communities but these differences may be explained by urbanisation. PMID:26618323

    Heavy metal concentrations and distribution were studied in sediments, seawater, and molluscs, and the possible heavy metal sources in the coastal waters of Guangdong Province, South China were discussed. The results showed that the concentrations of Cu, Pb, Zn, and Cr in sediments in eastern coastal waters were generally higher than those in the western coastal waters. However, concentrations of most metals in seawater and molluscs in western waters were higher than in the eastern waters, which was tightly related to the local economics and urbanization development, especially, the different industrial structure in two regions. The main heavy metal sources were attributed to the industrial and agricultural effluent, domestic sewage, and even waste gas. Furthermore, heavy metal contamination assessment indicated that high contamination levels of Cd, Zn, and Pb occurred in sediments in local areas, especially in the bays and harbors. The metal accumulation levels by molluscs ranked following the order of Cd > Cu > As > Zn > Pb > Cr, and the ecological risks introduced by heavy metals in different areas were in the order of Zhanjiang > Yangmao > Shantou > Shanhui.

    Full Text Available Bovine Taenia saginata cysticercus infections (also called bovine cysticercosis or beef measles is usually diagnosed in cattle only during post-mortem meat inspection. The aim of this study was to investigate the identification rates of these infections in and to identify predictors/determinants of variations in the identification rates in abattoirs in Gauteng province, South Africa.Retrospective data for over 1.4 million cattle carcasses inspected in 26 abattoirs between January 2010 and December 2013 were used for the study. The identification rates (proportion of bovine Taenia saginata cysticercus positive carcasses were computed and generalized estimating equations used to identify predictors/determinants of identification rates.The overall identification rate was 0.70% (95% CI: 0.45, 0.95. Significantly (p0.05 association was identified between identification rates and either the number of meat inspectors per abattoir or the provider of inspection services.Although no significant association was found between identification rates and provider of inspection services, follow-up studies will need to be done to specifically investigate the potential conflict of interest arising from the fact that abattoir owners hire meat inspection services directly. Capture of abattoir surveillance data needs to include farm address and for each case to be reported separately. Finally, information on the type of identified cysts (alive or calcified need to be collected to help better estimate risk to consumers. This study provides useful baseline data to guide future studies, surveillance and control efforts.

    Full Text Available Background: Thalassemia is the most common monogenic disease in South-East of Iran. Despite the 70% reduction in Iranian thalassemia cases after thalassemia control comprehensive program, 601 affected babies were born in Sistan and Balouchistan Province, Iran from 2002 to 2010, so this study aims at investigating the causes of new thalassemia cases.Methods: Data from this retrospective cross-sectional study was collected through interviews and information in the patients’ hospital records.Results: Data revealed that 52.4% of fathers and 78.4% of mothers of thalassemic children had elementary education or less. In addition, 78.6% of the couples did not undergo premarital screening for thalassemia and 71.2% of the couples were not notified of their own minor thalassemia until a child was born with major thalassemia. Of the diagnosed minor couples, about 25% did PND and the others did not carry out because mothers were unaware of proper gestational age and of the importance of this issue, financial problems, and the husbands’ disagreement to take the tests. Moreover, 16 mothers, in spite of being diagnosed of having a major fetus, refused to terminate the pregnancy.Conclusion: The most preventable causes for affected births include couples’ unawareness of being minor and unawares of the PND importance and process.

    Full Text Available Two well preserved specimens of Fuyuanperleidus dengi Geng et al., 2012 are described from the Upper Member of the Guanling Formation (Pelsonian, Anisian, Middle Triassic in Luoping County, Yunnan Province, South China. The attribution  to Perleidiformes is confirmed according to a combination of features such as the general skull pattern, with the large preoperculum showing a prominent infraorbital process, the maxilla with deep posterior region and a dentition made of  long and stout peg-like teeth with an acuminate apex, the deep mid-lateral flank scales and the caudal fin with epaxial fin rays. However, this taxon shows an unique arrangement of the squamation (here considered as autapomorphy given by the insertion of several scales in each vertical row posterior to the pelvic fin, just below the scales carrying the lateral line, when their depth decreases abruptly. Owing to this unique character, and  in spite of the very recent description of this genus, the authors considered necessary the erection of a new family, Fuyuanperleididae offering also new insights on the evolutionary trends and morphological specializations of the “subholosteans”. A cladistic analysis of the well known perleidiformes, with this taxon included, supports a possible monophyly of the order, and matches well the paleobiogeographic relationships of the Gondwana fresh-water taxa. The specialized deep-bodied Gondwana and Tethyan perleidiformes are independently evolved, ascertained by the parsimony analysis.

    Farmland is a fundamental resource for human survival and development. However, farmland fragmentation has become a serious problem, causing ecological damage and low crop production efficiency in many parts of the world. Based on remote sensing and socioeconomic data, we used landscape pattern indices, Morphological Spatial Pattern Analysis (MSPA), and Markov chain models to analyze the temporal and spatial pattern changes in farmland in South Jiangsu Province (the first "Modernization Demonstration Zone" in China) during 1985-2010. Our results demonstrated that the total farmland area decreased by ca. 24% and the farmland pattern became fragmented during 1985-2008: core farmland decreased and islet farmland increased. Additionally, the farmland patch density (PD) increased and three other landscape indices (NLSI, MESH, and COHESION) showed significant decreases. Although the fragmentation rate slowed after 2008, the convergence rate to a stationary farmland distribution became faster, and transitions tended to be less deterministic after 2000. Economic and population growth and policy changes positively contributed to this phenomenon. Therefore, the primary task of farmland protection should be to preserve contiguous farmlands and reduce scattered patches in order to promote farmland connectivity. PMID:26135496

    2002-07-01

    Full Text Available A participatory research model was used in six village communities in the Central Region of the North West Province of South Africa in order to achieve the following broad objectives : to obtain information on the challenges owners face in raising livestock in these areas and to evaluate the livestock owners' level of knowledge of internal parasites in their animals. Information obtained at participatory workshops clearly indicated a need for improvements in water supply, schools, job creation, and health services. Lack of pasture for grazing livestock was also cited as being important. Other most frequently mentioned livestock problems included 'gall sickness' (a vaguely defined condition not necessarily referring to anaplasmosis, parasites (both external and internal, chicken diseases and ingestion of plastic bags discarded in the environment. When livestock owners were questioned during individual interviews, most were able to identify the presence of parasites in either the live or dead animal. However, it seems likely that this is limited to the identification of tapeworms. It was found that most livestock owners use a combination of treatments, ranging from traditional to folklore to commercial. There were some difficulties in using the participatory methods since it was the first time that the facilitators and the communities had been exposed to them. Many communities had difficulty in dealing with the concept of finding solutions within the community, which is such an integral part of participatory methods.

    The causes and situation of exudative pleural effusion vary from one area to another. A cross-sectional study was conducted on 327 patients with exudative pleural effusion in South Khorasan province (Iran). The patients were older than 12 years and comprised 172 (52.6%) males and 155 (47.4%) females. The study commenced in 2007 with seven years duration. The Light’s criteria were used to define exudative effusion. Procedures including pleural fluid analysis, microbiological study, pleural biopsy, and systemic investigations were conducted to determine the special cause of pleural effusion. The mean age of the patients was 63.4±18.4 years. Malignancies, tuberculosis, and parapneumonia pleural exudation were diagnosed in 125 (38.2%), 48 (14.7%), and 45 (13.8%) cases, respectively. Among malignant effusions, metastasis from lung cancer made 48 (38.4%) of the cases. The origin of metastasis was not determined in 44 (35.2%) patients. The mean age of patients was not significantly different between malignant (66.9±14.3 years) and tuberculosis (63.9±19.7 years) cases (P=0.16). The older age of tuberculosis patients could be a new discussion point on the overall impression created on the subject of tuberculosis pleural exudation (TB-PLE) occurring in young people.

    Full Text Available Background and Aim: Congenital hypothyroidism (CH is among the most common endocrine disorders in children and a preventable cause of mental retardation. The present study was performed to determine the prevalence and related risk factors of hypothyroidism in neonates in South Khorasan.   Materials and Methods: This descriptive-retrospective study was conducted on the data collected through the Neonatal CH Screening Project in South Khorasan during four years (March 2006 - March 2010. Neonates whose TSH of the heel blood was ≥5 mU/L were recalled and if the serum TSH was ≥10 mU/L they were accounted as hypothyroid cases. Finally, SPSS software was used to analyze the obtained data.   Results: From 38987 neonates, 1248 cases (3.21% were recalled and serum TSH of 71 neonates was ≥10 mU/L which was a symptom of hypothyroidism. In the initial screening of hypothyroidism in neonates TSH of the heel blood in 45% was found to be 5-10 mU/L, in 20% it was 10-19.9, and in 35% it was ≥ 20. Prevalence of the disease was 1 in 549 living births. Hypothyroidism in boys was 6% more than girls.98.6% of the sick neonates' mothers did not have hypothyroidism 50.7 % of the cases lived in city.   Conclusion: Regarding the significance of the disease in developing mental retardation, it is necessary to persuade parents to have their neonates take part in neonatal hypothyroidism screening plan.

    Full Text Available A new high altitude montane species of Trichostetha Burmeister, 1842 is described from the Elandsberg range of the Western Cape interior. This represents the 14th species of the genus and the first to be reported with a description of its larva. It is a significant addition to the growing number of species that exhibit no adult feeding behaviour and a short period of activity restricted to the onset of summer. Larvae dwell in rock crevices, feeding on decomposing plant matter. The genus Trichostetha is heterogeneous and the complex variability observed in some species, especially T. capensis (Linnaeus, 1767, requires the re-instatement of taxa that were recently synonymised. Thus, T. bicolor Péringuey, 1907 is here re-proposed as a separate species and T. capensis hottentotta (Gory & Percheron, 1833 as a separate subspecies. Conversely, T. alutacea Allard, 1994 is recognised as a dark variety of T. signata (Fabricius, 1775 and is, consequently, synonymised with this species.

    A biomedical survey was conducted in 9 villages in the Malili area of South Sulawesi, Indonesia. Blood specimens were examined for malaria and microfilariae; stool specimens were examined for intestinal parasites. Malaria parasitemias were rare; Plasmodium falciparum was detected in 10 and P. vivax in 11 of 985 blood smears. Malayan filariasis was endemic to all villages surveyed. The overall prevalence of detectable microfilaremias was 15%, varying from 34% in Kawata to 1% in Nuha. Microfilarial densities, expressed as MfD50 averaged 8.0 and varied from 1.1 in Timampu to 16.0 in Karabbe. Intestinal parasites were common. Although Schistosoma japonicum was not found, 97% of the examined had one or more intestinal parasites as follows: Ascaris lumbricoides (74%), Trichuris trichiura (65%), hookworm (62%), Entamoeba coli (38%), Endolimax nana (10%), Entamoeba histolytica (6%), Iodamoeba bütschlii (4%), Entamoeba hartmanni (3%), Giardia lamblia (2%) Chilomastix mesnili (1%) and Enterobius vermicularis (1%). Strongyloides stercoralis larvae and Hymenolepis nana eggs were detected once each and heterophyid-like eggs were detected twice. PMID:364674

    Full Text Available Metagabbro, metadiabase and metabasalt of the Chah Palang and Me'raji mountains associated with Lower Paleozoic metamorphites are situated in the south of Arousan. Metabasites of these areas are relatively similar in terms of mineralogy and geochemical characteristics. Rock-forming minerals of the Me'raji metabasites are feldspar, amphibole, biotite, sphene, epidote, chlorite ± calcite. Metagabbro and metadiabase of the Chah Palang area are similar to the Me'raji metabasites in mineralogy and geochemistry. Volcanic rocks are overlain by metagabbros and consist of plagioclase, biotite, sphene, sanidine, chlorite, epidote and iron oxides. The rigid dykes, which are found in the volcanic units are associated with metagabbros and mineralogically are similar to the metavolcanics. Amphibolitic dykes are composed of amphibole, plagioclase and biotite with preferred orientation. Metabasites show limited range of differentiation. Me'raji metabasites are basalt and trachy-basalt in composition, whereas the Chah Palang ones present basalt and trachy-basalt composition. Similar to metabasites of the other parts of Iran, the studied basic rocks demonstrate alkaline to transitional chemical characteristic and are formed in an extensional environment by low-degree partial melting of a garnet-spinel peridotite. Metamorphic episodes have changed the studied rocks to amphibolite and greenschist, but the primitive igneous textures are preserved.

    Add regions of the wodd occupy up to 35% of the earth's surface, the basis of various definitions of climatic conditions,vegetation types or potential for food production. Due to their high ecological value, monitoring of add regions is necessary and modem vegetation studies can help in the conservation and management of these areas. The use of remote sensing for mapping of desert vegetation is difficult due to mixing of the spectral reflectance of bright desert soils with the weak spectral response of sparse vegetation. We studied the vegetation types in the semiarid to arid region of Mond Protected Area, south-west Iran, based on unsupervised classification of the Spot XS bands and then produced updated maps.Sixteen map units covering t2 vegetation types were recognized in the area based on both field works and satellite mapping. Halocnemum strobilaceum and Suaeda fruticosa vegetation types were the dominant types and Ephedra foliata,Salicornia europaaa-Suaeda heterophylla vegetation types were the smallest. Vegetation coverage decreased sharply with the increase in salinity towards the coastal areas of the Persian Gulf. The highest vegetation coverage belonged to the riparian vegetation along the Mond River, which represents the northern boundary of the protected area. The location of vegetation types was studied on the separate soil and habitat diversity maps of the study area, which helped in final refinements of the vegetation map produced.

Their relationship with nurses was poor (p < 0.05 as reported by 73% of participants with regard to maintenance of confidentiality. Participants reported key psychosocial variables such as inadequate sexual knowledge (61%, changing attitudes towards sex (58.9% and peer pressure (56.3% as contributory to high pregnancy rate. Recommendations were made to improve school health services, reproductive education in school curricula focussing on reproductive health, sexuality and guidance for future research.

  16. Uranium, thorium and potassium occurrences in the vicinity of hot springs in the northern neotectonic belt in the Eastern Cape Province, South Africa

    International Nuclear Information System (INIS)

    Gamma ray measurements were carried out along two parallel lines close to each of the hot springs using a RS 125 spectrometer to find the concentration (ppm) of U, Th, and K at Polile Tshisa, Aliwal North, and Badfontein hot springs. The RS 125 spectrometer is auto-stabilized on the naturally occurring U, Th, and K, and provides concentrations (ppm) of the radioelements. The results show that the concentration of thorium is higher, and is below the world average hazardous threshold of 7.4 ppm. Thorium is related to the occurrence of monazite seen at the scanning electron microscope. Higher ratios of U/K are indicative of an increase of uranium relative to potassium. Binary diagrams (Th-U, K-U, and K-Th) do not show a clear best fit except at Polile Tshisa hot spring where thorium shows a quasi positive correlation to potassium. In general, it can be concluded that the concentrations of these three radioelements are quite low, acceptable for groundwater, and could be hazardous to the health of humans and animals if exposed to long time radiations.

    Full Text Available TaqMan real-time PCR was used for the detection and quantitation of adenoviruses in Tyume River water samples over a 12-month period. A total of 72 samples were analysed, and 22 samples were positive for adenovirus. Of the positive samples, 18 were collected from downstream sampling points. Among the downstream sampling points, adenovirus detection rate increased with distance downstream, being 28%, 33%, and 39% for Alice, Drayini, and Manqulweni, respectively. The Alice sampling site had the highest concentrations of adenovirus ranging between 6.54×103 genome copies/L and 8.49×104 genome copies/L. The observed trend could have been expected considering the level of anthropogenic activities in areas along the lower stretch of Tyume River, with the major one being the effluent of treated and semi treated sewage from wastewater treatment facilities. Adenovirus detection was sporadic at most sampling sites. Multiplex conventional PCR was used for the detection of clinically important adenovirus species B, C, and F and their serotypes. Species C and F adenoviruses were detected in 77% and 18% of the samples, respectively. Most adenovirus positive samples were obtained from areas of increased population densities. The presence of adenoviruses may confirm the risk of its transmission to the human population.

    Escherichia coli remains a public health concern worldwide as an organism that causes diarrhea and its reservoir in raw milk may play an important role in the survival and transport of pathogenic strains. Diarrheagenic E. coli strains are diverse food-borne pathogens and causes diarrhea with varying virulence in humans. We investigated the prevalence of pathogenic E. coli in raw milk from two commercial dairy farms. Four hundred raw milk samples, 200 from each dairy farm, were screened for the presence of fliCH7, eagR, ial, eagg, lt, and papC genes. In dairy farm A, 100 E. coli were identified based on culture, oxidase and Gram staining, while 88 isolates from dairy farm B were identified in the same manner. Gene detection showed fliCH7 27 (54%) to be the highest gene detected from farm A and lt 2 (4%) to be the lowest. The highest gene detected in dairy farm B was fliCH7 16 (43.2%) and papC 1 (2.7%) was the least. The amplification of pathogenic genes associated with diarrheagenic E. coli from cows' raw milk demonstrates that potentially virulent E. coli strains are widely distributed in raw milk and may be a cause of concern for human health.

    Full Text Available Background: Job satisfaction and burnout have been recurring problems amongst nurses in the Republic of South Africa (RSA. As a result, nurses are still leaving the rural public sector in search of lucrative work at the urban and private sectors and in developed countries. Accordingly, Occupational Specific Dispensation (OSD was introduced as a strategy to ircumvent the problem. However, since the implementation of OSD in 2007, there have been no studies conducted regarding the level of job satisfaction amongst nurses after the implementation of OSD in the North-West Province, especially because each province has its own challenges that are unique to the area.Objectives: The study had two objectives: to describe the level of job satisfaction amongstprofessional and other category nurses (OCNs at a public hospital in the North-West Provinceand describe the perceptions of nurses about OSD and their intention to continue working inthe hospital.Method: A quantitative descriptive cross-sectional design was used. Stratified random sampling was used to select a sample of 92 professional nurses (PNs, 90 enrolled nurses and enrolled nursing assistants (Nursing Act 2005, which made a total of 182 participants. For the purpose of the study, the enrolled nurses and enrolled nursing assistants were referred to as OCNs. Data were collected using the Minnesota Satisfaction Questionnaire–short form and OSD statements and analysed with Statistical Package for Social Science (SPSS, version 18.Results: The majority of PNs (79.3%, n = 73 and OCNs (86.7%, n = 77 were dissatisfied with the working conditions and salary: PNs (80.4%, n = 74 and OCNs (87.8%, n = 79.

    Full Text Available In a semi-arid water scarce country like South Africa, the efficient use of limited water resources and measures to extend the service value of these resources is a prerequisite for achieving sustainable development. The conventional supply-sided management approach to water supply causes increased wastewater generation with accompanied increased pollution loads requiring higher levels of mitigation environmental pollution. Where disposal of wastewater treatment effluent takes place in rivers and natural water bodies, the lack of adequate natural compensating capacity of such water bodies typically result in severe ecological damage of the aquatic environment. With a shift of emphasis to a sustainable demand side management approach (as opposed to a supply side one, the avoidance of water wastage and high wastewater generation represents both resource conservation and environmental protection friendly approaches and contribute to overall sustainability. The integrated nature of water supply and wastewater management systems require an approach that considers these systems holistically. A new paradigm for water management is therefore needed to ensure that the issues of waste disposal and pollution are dealt with in a sustainable manner taking into account the emerging objectives of modern society for resource conservation and environmental protection. A balance therefore has to be found between the uses of additional fresh water resources as a means of satisfying en ever increasing water demand on the one hand and alternative unconventional resource exploration and employment, without the risk of depletion of natural available fresh water resource flow, irreversible harm to the environment and social and economic constraints. This paper explores wastewater and grey water reuse as unconventional resources in a qualitative manner within this balancing equation. It further proposes a methodology for deriving monetary indicator values for wastewater

    The northwestern Guizhou in the Yangtze Craton of south China has a tremendous potential of shale gas resource. In this paper, we present results from major and trace elements, total organic carbon, mineralogical composition analysis and petrophysical parameters to characterise shale weathering features. Further, the differences of black shale between underground and outcrops have also been presented to examine the changes of black shale after weathering. Our results show that the trace elements of shale have varying degrees of loss in the weathering leaching process, both in Niutitang shale and Longmaxi shale, the loss of B, V, Ni, Cu, Zn and Ba is obvious, but the element migration quantity in the formeris greater than in the latter. Decomposition of minerals such as pyrite, feldspar and calcite result in the leaching of Na, Ca, Mg and Fe. The loss rate of total organic carbon (TOC) in black shales ranges from 18% to 70% with an average of 43%; moreover, the loss of organic carbon in samples with high TOC contentis larger than in those samples with low TOC content. Results following the testing of porosity and permeability show that porosity increases significantly after weathering but permeability changes little. Furthermore, the increment of porosity is greater in the Niutitang shale (with more sulphide minerals) than in the Longmaxi shale, suggesting that the oxidation of sulphide minerals may have led to the formationof an acidic environment, causing the other minerals in the black shale to weather more quickly, thus resulting in increased porosity. The content of clay minerals in the core samples is slightly lesser than the outcrop samples, but the TOC content in the core samples is greater and has a larger specific surface area. This suggest that the TOC content played a decisive role on the specific surface area of shale. In addition, changes in the black shale caused by the weathering process mainly depend on the mineral composition and the TOC content in

    Surface winds have declined in many regions of the world over the past few decades. These trends are referred to as global stilling and have recently been observed in the Western Cape Province of South Africa. The potential consequences of such changes on ecosystem function and productivity are a particular concern for the highly diverse and endemic local flora, largely associated with the fynbos biome. Yet, few studies have directly examined the impact of wind in the region. In this study, we explored the importance of wind and other drivers of plant transpiration (E) in a stand of Leucospermum conocarpodendron (L.) Buek trees on the Cape Peninsula. Wind speeds can be high in the Cape and could play an important role in influencing the rate of E Overall, the influence of wind appeared to be significantly greater at night than during the day. While daytime E responded most strongly to changes in solar radiation (R(2) = 0.79) and vapour pressure deficit (R(2) = 0.57-0.67), night-time E (En) was primarily driven by wind speed (R(2) = 0.30-0.59). These findings have important implications for stilling and other aspects of climate change. Since En was found to be a regular and significant (P climate. Changes in other biophysical variables are, however, clearly important to consider in the current debate on the impact of climate change. PMID:27174701

    A high-resolution climate record from 163.00 kaBP to 113.80 kaBP has been obtained through TIMS-U series dating and carbon and oxygen isotope analysis of the three large stalagmites from two caves in the south of Guizhou Province, China. The record of the oxygen isotopes from the stalagmites reveals that the undulation characteristics between the cooling event of the glacial period and the warming event of the interglacial period in the research area can compare well to those of ice cores, lake sediments, loess and deep sea sediments on the scale of ten-thousand years or millennium time scale. The climate undulation provided by the record of the stalagmites has a coherence with the global changes and a tele-connection to the paleoclimate changes in the north polar region. Our results suggest that the direct dynamics of paleo-monsoon circulation changes reflected in the record of the stalagmites might be caused by changes of the global ice volume, and in turn related to various factors, including the solar radiation strength at the mid-latitudes in the Northern Hemisphere, the southern extension of the ice-rafted event in the North Atlantic, and changes of the equatorial Pacific sea surface temperature at the low-latitudes. Using δ18O values, we have calculated the temperatures and the results show that the temperature difference between the penultimate glacial period (with an average temperature of 8.1℃, and a minimum temperature range from 0.65℃ to -1.43℃ at stage 6 ) and the last interglacial period (with an average temperature of 18.24℃ at sub-stage 5e ) was about 10℃. This temperature difference from the record of the stalagmites corresponds in general to the record temperature variation (about 10℃) of measured ice cores. The climate records from the three stalagmites in the two caves have shown that the circulation strength of the Asian summer monsoon and the winter monsoon in the penultimate glacial period and the last interglacial period had a

    Full Text Available Abstract Background This work reports the determination of the levels of phthalate esters (dimethyl phthalate (DMP, diethyl phthalate (DEP, dibutyl phthalate (DBP, diethyl hexyl phthalate (DEHP and metals (lead, cadmium, manganese, zinc, iron, calcium in composite soil samples. The soil samples were collected randomly within the Muledane open dump, Thohoyandou, Limpopo province, South Africa. Control samples were collected about 200 m away from the open dump. The phthalate esters were separated and determined by capillary gas chromatography with a flame ionization detector, whilst the metals were determined by atomic absorption spectrophotometry. Results Open dump values for the phthalate esters and metals to be generally higher in comparison to control samples for DMP, DEP, DBP and DEHP – the mean values calculated were 0.31 ± 0.12, 0.21 ± 0.05, 0.30 ± 0.07, and 0.03 ± 0.01 mg/kg, respectively, for the open dump soil samples. Nonetheless, the mean open dump values for lead, cadmium, manganese, zinc, iron and calcium were 0.07 ± 0.04, 0.003 ± 0.001, 5.02 ± 1.92, 0.31 ± 0.02, 11.62 ± 9.48 and 0.12 ± 0.13 mg/kg, respectively. The results were compared statistically. Conclusion Our results revealed that the discarding of wastes into the open dump is a potential source of soil contamination in the immediate vicinity and beyond, via dispersal. Increased levels of phthalate esters and metals in the soil pose a risk to public health, plants and animals. Sustained monitoring of these contaminants is recommended, in addition to upgrading the facility to a landfill.

    Full Text Available The occurrence and distribution of Shigella species in water from the five river catchments in the North West province of South Africa were investigated. Shigella is a Gram-negative, non-motile, facultative anaerobic bacillus that causes shigellosis, an important cause of morbidity and mortality in high-risk populations (such as children, the elderly and immuno-compromised individuals that depend on river water. A total of 54 water samples collected in winter (April 2007 to July 2007 and summer (December 2007 to March 2008 were cultured on Salmonella-Shigella agar by the spread-plate method. Suspected Shigella isolates obtained were characterised by primary biochemical (Triple Sugar Iron agar and agglutination and molecular (polymerase chain reactions, PCR tests. Amplification of the invasion plasmid gene (ipaH by PCR was done to confirm the presence of Shigella spp. in water. In total, 214 Shigella boydii, 15 Shigella dysenteriae, 11 Shigella flexneri and 2 Shigella sonnei were confirmed by serotyping in both winter and summer samples. The ipaH gene (606 bp was present in 176 and 49 of the winter and summer isolates, respectively. The presence of Shigella spp. in water was confirmed with over 90% specificity. The need for more effective management of these river catchments and the provision of potable water and sanitation facilities is needed to minimise the occurrence and transmission of water-borne diseases caused by these and other pathogenic bacteria.

    Full Text Available Background: Visual impairment and blindness are major health problems worldwide, especially in the rural and remote areas of developing countries. Utilisation of eye care services is essential to reduce the burden of visual impairment and blindness, and it is therefore important that it is monitored.Objectives: The objectives of this study were to determine the level of utilisation of public eye care services and factors that might have influenced their usage in rural communities, Capricorn district, Limpopo Province, South Africa.Method: A population-based cross-sectional study design was used. Participants were residents in selected rural villages located within approximately 5 km of six Government hospitals. Following ethical approval and receipt of informed consent, a questionnaire with closed and open-ended questions was used to collect information on the utilisation of eye care services and factors that might influence utilisation. Descriptive statistics and Pearson’s Chisquare test were used to analyse and compare the data.Results: Many (62.7% of the respondents had used the government eye care services in the past. Over fifty-nine per cent (59.3% of them were satisfied with the services. Factors reported to influence utilisation (such as monthly income, knowledge of available services and the need for regular eye tests were positively associated with utilisation of eye care services in this study (p < 0.05.Conclusion: Utilisation of eye care services was relatively good, but varied significantly between sites. An awareness campaign by government and non-governmental organisations about eye care services may increase utilisation amongst rural communities.

    Full Text Available Background: South Africa has a high burden of tuberculosis (TB, with high human immunodeficiency virus (HIV-TB co-infection rates and the emergence of multidrugresistant TB.Objectives: To describe treatment outcomes and factors influencing outcomes amongst pulmonary TB (PTB patients in the Limpopo Province.Method: A retrospective review was conducted of data on the provincial electronic TB register (ETR.net for the years 2006 to 2010 (inclusive, and a random sample of 1200 records was selected for further analysis. The Chi square test was used to examine the influence of age, gender, health facility level, diagnostic category and treatment regimen on treatment outcomes.Results: Overall 90 617 (54.6% male PTB patients were registered between 2006 and 2010. Of the sampled 1200 TB cases, 72.6% were in persons aged 22 to 55 years and 86.2% were new cases. The TB mortality rate was 13.6% (much higher than the World Health Organization target of 3%, whilst the default rate was 9.8%. There was a strong association between age (P < 0.001, diagnostic category (P < 0.001, treatment regimen (P < 0.001, and health facility level (P < 0.001 and treatment outcome. Those aged 22–55, and 56–74 years were more likely to die (P < 0.05. Poor treatment outcomes were also associated with initial treatment failure, receiving treatment at hospital and treatment regimen II.Conclusion: The poor TB treatment outcomes in Limpopo, characterised by a high mortality and default rates, call for strengthening of the TB control programme, which should include integration of HIV and/or AIDS and TB services.

    Caring is typically constructed as a feminised practice, resulting in women shouldering the burden of care-related work. Health-seeking behaviours are also constructed as feminine and men have poorer health outcomes globally. Employing men as carers may not only improve the health of the men they assist but also be transformative with regards to gendered constructions of caring. Using semi-structured interviews and observational home visits, this study explored the techniques that community care workers employ when working with male clients. The empirical analysis draws on the perspectives of eight care workers and three of their male clients from the Cape Town area. Interviews reveal how care workers and clients perform and negotiate masculinities as they navigate hegemonic masculine norms that require men to act tough, suppress emotions and deny weakness and sickness. Both parties bump up against ideals of what it means to be a man as they strive to provide care and receive support. Community care workers avoid rupturing client performances of hegemonic masculinities which inhibit confession and support. To do this, they use techniques of indirectly broaching sensitive subjects, acting in a friendly way and being clear about the intention of their work. PMID:26967538

    Understanding and identifying the spatial-temporal changes in the natural environment is crucial for monitoring and evaluating conservation efforts, as well as understanding the impact of human activities on natural resources, informing responsible land management, and promoting better decision-making. Conservation areas are often under pressure from expanding farming and related industry, invasive alien vegetation, and an ever-increasing human settlement footprint. This study focuses on detecting changes to the Prince Alfred Hamlet commonage, near Ceres in the Cape Floral Kingdom. It was chosen for its high conservation value and significance as a critical water source area. The study area includes a fast-growing human settlement footprint in a highly productive farming landscape. There are conflicting development needs as well as risks to agricultural production, and both of these threaten the integrity of the ecosystems which supply underlying services to both demands on the land. Using a multi-disciplinary approach and high-resolution satellite imagery, land use and land cover changes can be detected and classified, and the results used to support the conservation of biodiversity and wildlife, and protect our natural resources. The aim of this research is to study the efficacy of using remote sensing and GIS techniques to detect changes to critical conservation areas where disturbances can be understood, and therefore better managed and mitigated before these areas are degraded beyond repair.

    Many attempts have been made to define and reconstruct the most plausible ecological and dietary niche of the earliest members of the human species. While earlier models emphasise big-game hunting in terrestrial, largely savannah environments, more recent scenarios consider the role of marine and aquatic foods as a source of polyunsaturated fatty acids (PUFA) and other brain-selective nutrients. Along the coast of southern Africa, there appears to be an association between the emergence of anatomically modern humans and accumulation of some of the earliest shell middens during the Middle Stone Age (200-40 ka). Fragmentary fossil remains classified as those of anatomically modern humans, along with marine food residues and numerous material cultural indicators of increased social and behavioural complexity have been recovered from coastal sites. In this paper, new information on the nutrient content of marine and terrestrial foods available to early modern humans in the southwestern Cape is presented and compared with existing data on the nutritional value of some wild plant and animal foods in Africa. The results suggest that coastal foraging, particularly the collection of abundant and predictable marine molluscs, would have allowed early modern humans to exploit some of the richest and most accessible sources of protein, micronutrients and longer-chain omega-6 and omega-3 fatty acids. Reliable and accessible sources of omega-3 eicosapentaenoic and docosahexaenoic acid are considerably more restricted in terrestrial foods. PMID:27457547

    Full Text Available OBJECTIVE: To determine the prevalence, associations and management of hypertension in the 25-74-year-old urban black population of Cape Town and examine the change between 1990 and 2008/09 in 25-64-year-olds. METHODS: In 2008/09, a representative cross-sectional sample, stratified for age and sex, was randomly selected from the same townships sampled in 1990. Cardiovascular disease risk factors were determined by administered questionnaires, clinical measurements and fasting biochemical analyses. Logistic regression models evaluated the associations with hypertension. RESULTS: There were 1099 participants, 392 men and 707 women (response rate 86% in 2008/09. Age-standardised hypertension prevalence was 38.9% (95% confidence interval (CI: 35.6-42.3 with similar rates in men and women. Among 25-64-year-olds, hypertension prevalence was significantly higher in 2008/09 (35.6%, 95% CI: 32.3-39.0 than in 1990 (21.6%, 95% CI: 18.6-24.9. In 2008/09, hypertension odds increased with older age, family history of hypertension, higher body mass index, problematic alcohol intake, physical inactivity and urbanisation. Among hypertensive participants, significantly more women than men were detected (69.5% vs. 32.7%, treated (55.7% vs. 21.9% and controlled (32.4% vs. 10.4% in 2008/09. There were minimal changes from 1990 except for improved control in 25-64-year-old women (1990∶14.1% vs. 2008/09∶31.5%. CONCLUSIONS: The high and rising hypertension burden in this population, its association with modifiable risk factors and the sub-optimal care provided highlight the urgent need to prioritise hypertension management. Innovative solutions with efficient and cost-effective healthcare delivery as well as population-based strategies are required.

    Full Text Available Background: In order to develop clinical judgement, nurses should be encouraged to become analytical and critical thinkers. Development of a portfolio of evidence (PoE of reflection on clinical experiences is one of the strategies that can be used to enhance analytical and critical thinking amongst nursing students. Students’ perceptions of the process are important in order to encourage their reflective practice. PoE compilation at a school of nursing at a university in the Western Cape includes evidence of students’ clinical learning which they present in a portfolio. The students are expected to reflect on their clinical learning experiences and include these reflections in their portfolios.Objective: To describe the perceptions of fourth-year nursing students regarding reflective practice whilst compiling their PoEs.Method: A qualitative design was used to explore the perceptions of registered fourth-year nursing students with regard to their reflective practice whilst compiling their PoEs. Purposive sampling was used for selection of participants. Three focus group discussions were held, each consisting of six to eight participants. Data saturation was reached during the third meeting. Tesch’s method of data analysis was used.Results: Findings revealed that reflection enabled the learners to gain experience and identify challenges related to the expected events and tasks carried out at the hospitals and in the classroom whilst developing their PoE.Conclusion: The compilation of a PoE was a good teaching and learning strategy, and the skills, experience and knowledge that the participants in this study acquired boosted their self-esteem, confidence and critical thinking. Reflection also assisted in self-directed learning.

    An assessment of the concentrations of selected polybrominated diphenyl ether (PBDE) congeners as well as BB 153 in leachate samples collected from three landfill sites within the city of Cape Town was conducted. A liquid-liquid extraction technique was employed for the isolation of all the target compounds from the leachate samples. Extracts obtained were further subjected to multi-layer column chromatography employing different forms of silica gel. The prepared samples were analysed using a high capillary gas chromatograph equipped with a micro-electron capture detector (GC-μECD). The overall mean concentrations of the total PBDEs, including BDE 209 ranged between 5.65 and 2,240, 0.28-20.5 and 1.66-1,170 ng/l for Bellville, Coastal Park, and Vissershok landfill sites, respectively. The mean concentrations of BB 153, which were generally low in most of the samples analysed, were 70.4, 7.14 and 8.16 ng/l for Bellville, Coastal Park and Vissershok sites, respectively. The influence of precipitation on the characteristics and quantity of leachate produced from the landfill sites investigated was most pronounced during the August/September sampling regime. Generally, the trend observed in this study clearly indicated a wide variation in the levels of these contaminants in all the landfill sites studied from one sampling period to the other. However, the principal component analysis revealed that the release of these contaminants might be associated with two or three possible sources. This study further confirmed the relevance of landfill leachate as an important source of PBDE contamination of the environment, especially the groundwater and surface water sources. PMID:22350446

    Hunan province, Central South China, is a well-known nonferrous metal base in China. Mine exploiting and processing there, however, often lead to heavy metal pollution of farmland. To study the effects of mining activities on the soil environmental quality, four representative paddy fields, the HSG, SNJ, NT and THJ, in Y county, northern Hunan province, were investigated. It was found that the streams running through the HSG, SNJ and NT are severely contaminated due to the long-term discharge of untreated mineral wastewater from local indigenous mining factories. The stream at the HSG, for example, is brownish red in color, with high concentrations of Cu, Zn, Cd, Fe and Mn. The concentrations of Cu, Zn and Cd in all the stream water of the HSG, SNJ and NT exceed the maximum allowable levels of the Agricultural Irrigation Water Criteria of China. Correspondingly, the HSG, SNJ and NT are heavily polluted by Cu, Zn and Cd due to the long-term irrigation with the contaminated stream water. In comparison, both stream water and paddy fields of the THJ, far away from mining areas, are not contaminated by any heavy metals and hence regarded as a control in this study. The rice grain produced at the HSG, SNJ and NT has a high risk of Cd contamination. The rate of rice grain produced in the four paddy fields in Y county with Cd exceeding the safe level (Cd, 0.2 μg g-1) specified by the National Standards for Rice Quality and Safety of China reaches 90%. Cd content in the rice grain is positively significantly correlated with that in the paddy fields, especially with the content of diethylenetriaminepentaacetic acid (DTPA) - extracted Cd, suggesting that the heavy metal pollution of paddy fields has already posed a high risk to rice safety and human health. Soil enzyme activities and microbial biomass are significantly inhibited by the heavy metal pollution of the paddy fields. Microbial biomass C and N (MBC and MBN) at a severely contaminated site of the HSG are only 31

    Full Text Available Introduction The Garmab copper deposit is located northeast of Qaen (South Khorasan province in the1:100,000 scale map of Abiz in the eastern tectonic zone of Iran. It is hosted by Late Paleocene-Eocene lava flows consisting mainly of andesite, trachy¬andesite, andesite-basalt and basalt lavas, as well as pyroclastic rocks, including tuffs and ignimbrites. The Lut Block has undergone intense magmatic activitywith a variety of geochemical characteristics due to changing tectonic conditions (e.g., compression during subduction followed by tensional conditions; Karimpour et al., 2012; Zarrinkoub et al., 2012. The Lut Block has a great potential for the discovery of new mineral deposits, like the Mahrabad and Khonik porphyry copper-gold deposits (Malekzadeh shafarodi, 2009, the Dehsalam porphyry copper deposit (Arjmandzadeh, 2011, high sulfidation epithermal gold deposits such as Chah Shalghami (Karimpour, 2005 and IOCG deposits such as Kuh-E-Zar and Qaleh Zari (Mazlomi et al., 2008. Materials and methods After field studies of the Garmab area, 32 thin sections and 21 polished sections were prepared for petrological and mineralogical studies.In addition, 10 least-altered and fractured samples of volcanic rocks were selected for geochemical studies. Major oxides were determined using XRF analyses at the Zarazma laboratory. Induced polarization and resistivity geophysical data were collected and correlated with geological and alteration maps. The geophysical datawere collectedfrom 420 individual points, using a dipole-dipole arrangement along five profiles separated 60m apart.This covered the study area entirely. After a change in the mineralization trend was observed,additional profileswere designed, twoon bearings of 25º and three on 75º. Results The Garmab volcanic rocks exhibit typical geochemical characteristics of subduction zone magmas including strong enrichment in LILE and depletion in HFSE. Based on the discrimination plot of Irvine and

    Full Text Available Abstract Background The prevention of unintended pregnancies among HIV positive women is a neglected strategy in the fight against HIV/AIDS. Women who want to avoid unintended pregnancies can do this by using a modern contraceptive method. Contraceptive choice, in particular the use of long acting and permanent methods (LAPMs, is poorly understood among HIV-positive women. This study aimed to compare factors that influence women's choice in contraception and women's knowledge and attitudes towards the IUD and female sterilization by HIV-status in a high HIV prevalence setting, Cape Town, South Africa. Methods A quantitative cross-sectional survey was conducted using an interviewer-administered questionnaire amongst 265 HIV positive and 273 HIV-negative postpartum women in Cape Town. Contraceptive use, reproductive history and the future fertility intentions of postpartum women were compared using chi-squared tests, Wilcoxon rank-sum and Fisher's exact tests where appropriate. Women's knowledge and attitudes towards long acting and permanent methods as well as factors that influence women's choice in contraception were examined. Results The majority of women reported that their most recent pregnancy was unplanned (61.6% HIV positive and 63.2% HIV negative. Current use of contraception was high with no difference by HIV status (89.8% HIV positive and 89% HIV negative. Most women were using short acting methods, primarily the 3-monthly injectable (Depo Provera. Method convenience and health care provider recommendations were found to most commonly influence method choice. A small percentage of women (6.44% were using long acting and permanent methods, all of whom were using sterilization; however, it was found that poor knowledge regarding LAPMs is likely to be contributing to the poor uptake of these methods. Conclusions Improving contraceptive counselling to include LAPM and strengthening services for these methods are warranted in this setting

    Full Text Available Men-who-have-sex-with-men (MSM are at high risk of HIV and sexually transmitted infection (STI transmission. Asymptomatic STIs are common in MSM and remain undiagnosed and untreated where syndromic management is advocated. Untreated STIs could be contributing to high HIV rates. This study investigated symptomatic (SSTI and asymptomatic STIs (ASTIs in MSM in Cape Town.MSM, 18 years and above, were enrolled into this study. Participants underwent clinical and microbiological screening for STIs. Urine, oro-pharyngeal and anal swab specimens were collected for STI analysis, and blood for HIV and syphilis screening. A psychosocial and sexual questionnaire was completed. STI specimens were analysed for Neisseria gonorrhoeae (NG and Chlamydia trachomatis (CT infection.200 MSM were recruited with a median age of 32 years (IQR 26-39.5. Their median number of sex partners within the last year was 5 (IQR 2-20. 155/200 (78% reported only male sex partners while 45/200 (23% reported sex with men and women. 77/200 (39% reported transactional sex. At enrolment, 88/200 (44% were HIV positive and 8/112 (7% initially HIV-negative participants seroconverted during the study. Overall, 47/200 (24% screened positive for either NG or CT. There were 32 MSM (16% infected with NG and 7 (3.5% of these men had NG infections at two anatomical sites (39 NG positive results in total. Likewise, there were 23 MSM (12% infected with CT and all these men had infections at only one site. Eight of the 47 men (17% were infected with both NG and CT. ASTI was more common than SSTI irrespective of anatomical site, 38 /200 (19% versus 9/200 (5% respectively (p<0.001. The anus was most commonly affected, followed by the oro-pharynx and then urethra.

    Full Text Available Abstract Background Due to a paucity of data regarding the availability and efficacy of equipment, health promotion methods and materials currently used by health professionals for the management of patients with non-communicable diseases (NCDs at primary health care (PHC facilities in Cape Town, an audit was undertaken. Methods A multi-centre cross-sectional study was undertaken to interview patients (n = 580 with NCDs at 30 PHC facilities. A questionnaire was used to obtain information on preferences for health promotion methods for lifestyle modification. Individual semi-structured interviews were conducted with selected health professionals (n = 14 and captured using a digital recorder. Data were transferred to the Atlas ti software programme and analysed using a thematic content analysis approach. Results Blood pressure measurement (97.6% was the most common diagnostic test used, followed by weight measurement (88.3%, urine (85.7% and blood glucose testing (80.9%. Individual lifestyle modification counselling was the preferred health education method of choice for the majority of patients. Of the 64% of patients that selected chronic clubs/support groups as a method of choice, only a third rated this as their first choice. Pamphlets, posters and workshops/group counselling sessions were the least preferred methods with only 9%, 13% and 11% of patients choosing these as their first choice, respectively. In an individual counselling setting 44.7% of patients reported that they would prefer to be counselled by a doctor, followed by a nurse (16.9%, health educator (8.8% and nutrition advisor (4.8%. Health professionals identified numerous barriers to education and counselling. These can be summarised as a lack of resources, including time, space and equipment; staff-related barriers such as staff shortage and staff turnover; and patient-related barriers such as patient load and patient non-compliance. Conclusion The majority of patients

    Full Text Available Smoking may worsen the disease outcomes in patients with Crohn's disease (CD, however the effect of exposure to second-hand cigarette smoke during childhood is unclear. In South Africa, no such literature exists. The aim of this study was to investigate whether disease phenotype, at time of diagnosis of CD, was associated with exposure to second-hand cigarette during childhood and active cigarette smoking habits.A cross sectional examination of all consecutive CD patients seen during the period September 2011-January 2013 at 2 large inflammatory bowel disease centers in the Western Cape, South Africa was performed. Data were collected via review of patient case notes, interviewer-administered questionnaire and clinical examination by the attending gastroenterologist. Disease phenotype (behavior and location was evaluated at time of diagnosis, according to the Montreal Classification scheme. In addition, disease behavior was stratified as 'complicated' or 'uncomplicated', using predefined definitions. Passive cigarette smoke exposure was evaluated during 3 age intervals: 0-5, 6-10, and 11-18 years.One hundred and ninety four CD patients were identified. Cigarette smoking during the 6 months prior to, or at time of diagnosis was significantly associated with ileo-colonic (L3 disease (RRR = 3.63; 95% CI, 1.32-9.98, p = 0.012 and ileal (L1 disease (RRR = 3.54; 95% CI, 1.06-11.83, p = 0.040 compared with colonic disease. In smokers, childhood passive cigarette smoke exposure during the 0-5 years age interval was significantly associated with ileo-colonic CD location (RRR = 21.3; 95% CI, 1.16-391.55, p = 0.040. No significant association between smoking habits and disease behavior at diagnosis, whether defined by the Montreal scheme, or stratified as 'complicated' vs 'uncomplicated', was observed.Smoking habits were associated with ileo-colonic (L3 and ileal (L1 disease at time of diagnosis in a South African cohort.

    Full Text Available Abstract Background In order to ensure that legalized abortion in South Africa improves reproductive health, women must know that abortion is a legal option in the case of unwanted pregnancy. This study investigated knowledge of abortion legislation eight years after the introduction of legal abortion services in one province of South Africa. Methods In 2004/2005, we conducted a cross-sectional study among 831 sexually-active women attending 26 public health clinics in one urban and one rural health region of the Western Cape Province. Results Thirty-two percent of women did not know that abortion is currently legal. Among those who knew of legal abortion, few had knowledge of the time restrictions involved. Conclusion In South Africa there is an unmet need among women for information on abortion. Strategies should be developed to address this gap so that women are fully informed of their rights to a safe and legal termination of pregnancy.

    Full Text Available The Cape mountain zebra (Equus zebra zebra is one of the rarest species of mammals in South Africa, and is threatened with extinction. At present there are less than 200 in existence, of which approximately 160 occur in the Mountain Zebra National Park near Cradock. Because of the rarity of the species and the undesirable concentration of the majority in an area of only 6 536 ha, a post-mortem examination is performed, if possible, on all animals to establish cause of death with the purpose of preventing large-scale mortalities. This is done even if the carcass is in a fairly advanced state of decomposition. Amongst the examinations so performed were two zebra which were believed to have died as a result of intraventricular thrombosis. The rarity of this condition and of the Cape mountain zebra makes a report on these cases necessary.

    The present study was aimed at documenting medicinal plants used for the treatment of tuberculosis (TB) by the Bapedi traditional healers in three districts of the Limpopo Province, South Africa. Fifty two traditional healers from 17 municipalities covering Capricorn, Sekhukhune and Waterberg districts were interviewed between January and July 2011. Twenty one medicinal plant species belonging to 20 genera and 18 families were documented. The majority (61.9%) are indigenous and the rest are exotics, found near homes as weeds or cultivated in home gardens as ornamentals or food plants. Hyacinthaceae, Moraceae and Rutaceae families were the most represented families in terms of species numbers (9.5% each). Herbs and trees (38% each) constituted the largest proportion of the growth forms of the medicinal plants used. Tuberculosis remedies were mostly prepared from leaves (34%) followed by roots (21%). The therapeutic claims made on medicinal plants used to treat TB by the Bapedi traditional healers are well supported by literature, with 71.4% of the species having antimicrobial properties or have similar ethno medicinal uses in other countries. This study therefore, illustrates the importance of medicinal plants in the treatment and management of TB in the Limpopo Province, South Africa. PMID:24146456

    The RAIN project (Regional Archives for Integrated iNvestigations), funded by the German Federal Ministry of Education and Research (BMBF), focuses on closely integrated investigations of terrestrial and marine geoarchives from southern Africa in order to assess environmental changes during the late Quaternary. For this purpose, various marine and terrestrial sediment records from the three major rainfall zones of South Africa (winter-, summer- and year-round rainfall zone) were recovered and analysed applying a wide range of methods (e.g., sedimentology, seismic stratigraphy, geochronology, organic and inorganic geochemistry, mineralogy, stable isotopes, micropalaeontology, palynology). In this contribution, we present results and interpretations obtained from a 30.5 m sediment core retrieved from the coastal lake Eilandvlei located within the year-round rainfall zone. Geochemical investigations (Ca, Sr, total inorganic carbon) indicate major changes in the sediment carbonate contents which were linked to variations in the marine influence received at the site throughout the covered period. The interpretation of carbonates reflecting a varying marine influence is corroborated by micropalaeontological analyses (viz. ostracod and diatom assemblages) which reveal strong similarities with the geochemical data. In order to establish a reliable radiocarbon (14C) chronology for this record, it is of particular importance to consider the impact of 14C-depleted ("old") marine carbon contained in the measured samples causing reservoir effects. Therefore, two marine molluscan shells collected alive before AD 1950 ("pre-bomb") were analysed to determine the regional marine reservoir offset (ΔR). The obtained ΔR values of 134 ± 38 and 161 ± 38 14C yrs represent the first data available for the south coast of South Africa. However, the application of the resulting average ΔR = 148 ± 54 14C yrs for the calibration of the entire Eilandvlei record underestimates the

    HIV prevalence and incidence in South Africa remain high, making HIV a part of everyday life. Community narratives on HIV treatment and prevention are important and influence official and unofficial health messaging and community perceptions and understandings of HIV. We explore how contributors and the columnist of an agony aunt column position HIV relative to choices made about love, partnership, and sex over three years. We analysed all columns of an agony aunt series (Antie Mona) published between December 2012 and November 2015. The column is published in a South African, Afrikaans-language newspaper "Son", prioritising sensationalist news items. Trends were identified through narrative analysis. Data were managed in ATLAS.ti and inductive, iterative coding conducted. It was found that letters to the agony aunt rarely refer to HIV directly (less than 7%). Euphemisms such as diseases of the flesh and the great flu were more commonly used instead of HIV or AIDS. Letters addressed HIV in three ways: direct references to experiences living with HIV; direct questions about HIV prevention; and scenarios where HIV could (from a public health perspective) have been the main concern, but everyday issues took precedence. The majority of letters fell into this latter category where the writers focused on the immediate concerns of good sexual relations, problems related to love and romantic relationships, good moral behaviour of others, and issues of oppressive life conditions rather than on HIV directly. The findings illustrate that informal, public contributions to health information, such as agony aunts, are important narratives that inform popular perspectives on HIV and health. A better appreciation of this context would allow health implementers to ensure that these role players receive updated health messaging to avoid the risk of HIV-related stigma where HIV is used as a moral rod to punish perceived moral transgressions.
