Population specific genetic heterogeneity of familial hypercholesterolemia in South Africa.

Science.gov (United States)

Smyth, Natalie; Ramsay, Michèle; Raal, Frederick J

2018-04-01

To describe the prevalence and population-specific genetic heterogeneity of familial hypercholesterolemia in South Africa. This review highlights the paucity of data on familial hypercholesterolemia in South Africa, and the urgent need to uncover the mutation profiles in lipid-associated genes, causing an increase in LDL-cholesterol in the different ethnic groups. Case reports and small studies have shown that familial hypercholesterolemia, although apparently uncommon, is present in black Africans. Local founder effects have led to an increased prevalence of familial hypercholesterolemia in several South African populations: Afrikaner founder mutations (c.681 C>G, c.1285 G>A, c.523 G>A), Ashkenazi founder mutation (c.654_656del) and possible Indian founder mutation (c.2054 C>T). Preliminary data in black Africans with elevated LDL-cholesterol identified a possible common mutation, c.137_142del. The South African multiethnic society and well described founder effects emphasize the need for differential approaches to diagnosis and management of familial hypercholesterolemia. Studies involving larger cohorts and inclusive of different ethnicities are paramount to establishing an accurate prevalence of familial hypercholesterolemia in black Africans, not only in South Africa but in the Sub-Saharan African region. It is clear that the estimated world prevalence of one in 250 cannot be generally applied across African populations.

Characterization of the genetic variation present in CYP3A4 in three South African populations

Directory of Open Access Journals (Sweden)

Britt Ingrid Drögemöller

2013-02-01

Full Text Available TThe CYP3A4 enzyme is the most abundant human cytochrome P450 and is regarded as the most important enzyme involved in drug metabolism. Inter-individual and inter-population variability in gene expression and enzyme activity are thought to be influenced, in part, by genetic variation. Although Southern African individuals have been shown to exhibit the highest levels of genetic diversity, they have been under-represented in pharmacogenetic research to date. Therefore, the aim of this study was to identify genetic variation within CYP3A4 in three South African population groups comprising of 29 Khoisan, 65 Xhosa and 65 Mixed Ancestry individuals. To identify known and novel CYP3A4 variants, 15 individuals were randomly selected from each of the population groups for bi-directional Sanger sequencing of approximately 600 bp of the 5’-upstream region and all thirteen exons including flanking intronic regions. Genetic variants detected were genotyped in the rest of the cohort. In total, 24 SNPs were detected, including CYP3A4*12, CYP3A4*15, and the reportedly functional CYP3A4*1B promoter polymorphism, as well as two novel non-synonymous variants. These putatively functional variants, p.R162W and p.Q200H, were present in two of the three populations and all three populations, respectively, and in silico analysis predicted that the former would damage the protein product. Furthermore, the three populations were shown to exhibit distinct genetic profiles. These results confirm that South African populations show unique patterns of variation in the genes encoding xenobiotic metabolizing enzymes. This research suggests that population-specific genetic profiles for CYP3A4 and other drug metabolizing genes would be essential to make full use of pharmacogenetics in Southern Africa. Further investigation is needed to determine if the identified genetic variants influence CYP3A4 metabolism phenotype in these populations.

The arrival to the United States of the Africanized honey bee, a hybrid between European subspecies and the African subspecies Apis mellifera scutellata, is a remarkable model for the study of biological invasions. This immigration has created an opportunity to study the dynamics of secondary contact of honey bee subspecies from African and European lineages in a feral population in South Texas. An 11-year survey of this population (1991-2001) showed that mitochondrial haplotype frequencies changed drastically over time from a resident population of eastern and western European maternal ancestry, to a population dominated by the African haplotype. A subsequent study of the nuclear genome showed that the Africanization process included bidirectional gene flow between European and Africanized honey bees, giving rise to a new panmictic mixture of A. m. scutellata- and European-derived genes. In this study, we examined gene flow patterns in the same population 23 years after the first hybridization event occurred. We found 28 active colonies inhabiting 92 tree cavities surveyed in a 5.14 km(2) area, resulting in a colony density of 5.4 colonies/km(2). Of these 28 colonies, 25 were of A. m. scutellata maternal ancestry, and three were of western European maternal ancestry. No colonies of eastern European maternal ancestry were detected, although they were present in the earlier samples. Nuclear DNA revealed little change in the introgression of A. m. scutellata-derived genes into the population compared to previous surveys. Our results suggest this feral population remains an admixed swarm with continued low levels of European ancestry and a greater presence of African-derived mitochondrial genetic composition.

Breakfast habits by using questionnaires, were established in a total of 4717 South African pupils of 16 to 18 yr. In the groups of rural and urban Black, Indian, European-African-Malay, and white pupils studied, respective proportions who had no solid breakfast (both sexes combined) were approximately 21, 19, 13, 13, and 14%. Proportions who had only porridge or bread (or toast) plus drink were 77, 73, 61, 71, and 56%. Such breakfast provided ranges of means of 223 to 345 kcal, 9 to 14 g protein, 7 to 18 g fat, 51 to 185 mg calcium, and 3.2 to 5.1 mg iron. Proportions who had a cooked breakfast (including egg, meat, fish), eaten with or without a cereal food, were 1, 4, 17, 8, and 29%. Such meals contributed means of 495 to 704 kcal, 11 to 26 g protein, 24 to 39 g fat, 110 to 225 mg calcium, and 3.9 to 5.5 mg iron. In the South African groups studied, the issue of breakfast or no breakfast had no clear-cut bearing on weight, height, class position, or frequency of absence from school. The degree by which, in a given community, nutrition in general and breakfast in particular, regulates health and/or academic performance, needs proper research in prospective studies.

Human leukocyte antigen class I (A, B and C) allele and haplotype variation in a South African Mixed ancestry population.

Science.gov (United States)

Loubser, Shayne; Paximadis, Maria; Tiemessen, Caroline T

South Africa has a large (∼53million), ethnically diverse population (black African, Caucasian, Indian/Asian and Mixed ancestry) and a high disease burden (particularly HIV-1 and Mycobacterium tuberculosis). The Mixed ancestry population constitutes ∼9% of the total population and was established ∼365years ago in the Western Cape region through interracial mixing of black Africans, Europeans and Asians. Admixed populations present unique opportunities to identify genetic factors involved in disease susceptibility. Since HLA genes are important mediators of host immunity, we investigated HLA-A, -B and -C allele and haplotype diversity in 50 healthy, unrelated individuals recruited from the Mixed ancestry population.

SADCC: challenging the "South African connection.".

Science.gov (United States)

Liebenow, J G

1982-01-01

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

Unequal contribution of native South African phylogeographic lineages to the invasion of the African clawed frog, Xenopus laevis, in Europe

Directory of Open Access Journals (Sweden)

Charlotte De Busschere

2016-02-01

Full Text Available Due to both deliberate and accidental introductions, invasive African Clawed Frog (Xenopus laevis populations have become established worldwide. In this study, we investigate the geographic origins of invasive X. laevis populations in France and Portugal using the phylogeographic structure of X. laevis in its native South African range. In total, 80 individuals from the whole area known to be invaded in France and Portugal were analysed for two mitochondrial and three nuclear genes, allowing a comparison with 185 specimens from the native range. Our results show that native phylogeographic lineages have contributed differently to invasive European X. laevis populations. In Portugal, genetic and historical data suggest a single colonization event involving a small number of individuals from the south-western Cape region in South Africa. In contrast, French invasive X. laevis encompass two distinct native phylogeographic lineages, i.e., one from the south-western Cape region and one from the northern regions of South Africa. The French X. laevis population is the first example of a X. laevis invasion involving multiple lineages. Moreover, the lack of population structure based on nuclear DNA suggests a potential role for admixture within the invasive French population.

Republic of South Africa: unraveling the population puzzle. Country profile.

Science.gov (United States)

Spain, D

1984-06-01

This discussion of the Republic of South Africa focuses on population growth, regions and cities, ethnicity and religion of the population, age distribution, housing and households, education, employment, income, and marketing and communication. South Africans, condemmed by the world community for their policy of racial discriminatioon, contend that outsiders fail to understand the system they legalized in 1948. Apartheid calls for developing different political institutions for blacks and whites in preparation for their eventual separation. According to this reasoning, black Africans are not considered permanent residents of South Africa, but rather of the "homelands" to which each tribal group has been assigned by the government. 4 homelands have been made independent, and if the remaining 6 become independent as scheduled, South Africa theoretically will no longer have any black citizens. Under this plan, nearly 90% of the current area of South Africa would go to whites, while the remaining 10% would be divided among the 10 homelands. The UN has condemmed the homelands policy, and no country has recognized their independence. By law South Africa has 4 distinct populations: Africans, whites, coloureds, and asians. Rhe combination of Afrikaners and British makes up the white population. Whites are in the minority and numbered only 4.7 million in 1983, or 15% of the total population. Since whites rule the country, their importance is far disproportionate to their numbers. There were 2.7 million coloureds in 1983, approximately 9% of all South Africans. Black africans, the single largest population group, numbered 22.7 million in 1983, or 73% of the total population. Blacks are divided in 10 subgroups corresponding to the 10 ethnicallyy based homelands. The largest groups are the Zulu (5.9 million in 1981) and the Xhosa (3.1 million). Population growth varies by race. The annual growth rate for the entire country was 2.4% in 1983, but for blacks it was 2.7% and for

2018-01-01

The population of Zulu sheep is reported to have declined by 7.4% between 2007 and 2011 due to crossbreeding. There is insufficient information on the genetic diversity of the Zulu sheep populations in the different area of KwaZulu Natal where they are reared. The study investigated genetic variation and genetic structure within and among eight Zulu sheep populations using 26 microsatellite markers. In addition, Damara, Dorper and South African Merino breeds were included to assess the genetic relationship between these breeds and the Zulu sheep. The results showed that there is considerable genetic diversity among the Zulu sheep populations (expected heterozygosity ranging from 0.57 to 0.69) and the level of inbreeding was not remarkable. The structure analysis results revealed that Makhathini Research Station and UNIZULU research station share common genetic structure, while three populations (Nongoma, Ulundi and Nquthu) had some admixture with the exotic Dorper breed. Thus, there is a need for sustainable breeding and conservation programmes to control the gene flow, in order to stop possible genetic dilution of the Zulu sheep.

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

2014-03-01

We assessed the effectiveness of South Africa's Firearm Control Act (FCA), passed in 2000, on firearm homicide rates compared with rates of nonfirearm homicide across 5 South African cities from 2001 to 2005. We conducted a retrospective population-based study of 37 067 firearm and nonfirearm homicide cases. Generalized linear models helped estimate and compare time trends of firearm and nonfirearm homicides, adjusting for age, sex, race, day of week, city, year of death, and population size. There was a statistically significant decreasing trend regarding firearm homicides from 2001, with an adjusted year-on-year homicide rate ratio of 0.864 (95% confidence interval [CI] = 0.848, 0.880), representing a decrease of 13.6% per annum. The year-on-year decrease in nonfirearm homicide rates was also significant, but considerably lower at 0.976 (95% CI = 0.954, 0.997). Results suggest that 4585 (95% CI = 4427, 4723) lives were saved across 5 cities from 2001 to 2005 because of the FCA. Strength, timing and consistent decline suggest stricter gun control mediated by the FCA accounted for a significant decrease in homicide overall, and firearm homicide in particular, during the study period.

Peltzer, Karl

2017-05-09

The study aims to investigate sleep duration in four different population groups in a national probability sample of older South Africans who participated in the Study of Global Ageing and Adult Health (SAGE) Wave 1. A national population-based cross-sectional study with a sample of 3284 aged 50 years or older in South Africa was conducted in 2008. The questionnaire included socio-demographic characteristics, health variables, and self-reported sleep duration. Results indicate that White Africans compared to other population groups had the lowest mean sleep duration (7.88 h among men and 7.46 h among women). The prevalence of short sleep was the highest among both men and women among the White African (18.8% in men and 16.9% in women) and Indian or Asian African population groups (14.5% in men and 17.1% in women), and lowest among both men and women in the Black African (7.0% in men and 6.5% in women) and multi-ancestry population groups (15.6% in men and 12.7% in women). The prevalence of long sleep was among both men and women the highest in the Black African population group (56.2% in men and 58.5% in women), and the lowest in the White African population group (36.4% in men and 24.3% in women). In a Poisson regression model, adjusted for sociodemographics and chronic disease status, coming from the male and female White African population group was associated with short sleep. In addition, coming from the Indian or Asian African population group was associated with short sleep. No population group differences were found regarding long sleep prevalence. White Africans reported more short sleep duration than the other population groups, while there were no racial or ethnic differences in long sleep. White Africans are more likely to have sleep durations that are associated with negative health outcomes. An explanation of the high short sleep prevalence among White Africans may be related to their racial or ethnic minority status in South Africa.

Full Text Available Background: In South Africa, pulmonary tuberculosis (PTB remains a problem of epidemic proportions. Despite evidence demonstrating persistent lung impairment after PTB cure, few population-based South African studies have investigated this finding. Pulmonary rehabilitation post-cure is not routinely received. Objectives: To determine the effects of PTB on lung function in adults with current or past PTB. To determine any association between PTB and chronic obstructive pulmonary disease (COPD. Methods: This study was observational and cross-sectional in design. Participants (n = 55 were included if they were HIV positive on treatment, had current PTB and were on treatment, and/or had previous PTB and completed treatment or if they were healthy adult subjects with no history of PTB. A sample of convenience was used with participants coming from a similar socio-economic background and undergoing spirometry testing. Multiple regression analyses were conducted on each lung function variable. Results: Compared to normal percentage-predicted values, forced expiratory volume in 1 second (FEV1 , forced vital capacity (FVC and FEV1 :FVC were significantly reduced in those with current PTB by 23.39%, 15.99% and 6.4%, respectively. Both FEV1 and FVC were significantly reduced in those with past PTB by 11.76% and 10.79%, respectively. There was no association between PTB and COPD – those with previous PTB having a reduced FEV1 :FVC (4.88% less than the norm, which was just short of significance (p = 0.059. Conclusions: Lung function is reduced both during and after treatment for PTB and these deficits may persist. This has implications regarding the need for pulmonary rehabilitation even after medical cure. Keywords: Lung function, pulmonary, tuberculosis

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

A Review of Dietary Surveys in the Adult South African Population from 2000 to 2015

Directory of Open Access Journals (Sweden)

Zandile J. Mchiza

2015-09-01

Full Text Available One serious concern of health policymakers in South Africa is the fact that there is no national data on the dietary intake of adult South Africans. The only national dietary study was done in children in 1999. Hence, it becomes difficult to plan intervention and strategies to combat malnutrition without national data on adults. The current review consequently assessed all dietary studies in adults from 2000 to June 2015 in an attempt to portray typical adult dietary intakes and to assess possible dietary deficiencies. Notable findings were that, in South Africa micronutrient deficiencies are still highly prevalent and energy intakes varied between very low intakes in informal settlements to very high intakes in urban centers. The most commonly deficient food groups observed are fruit and vegetables, and dairy. This has been attributed to high prices and lack of availability of these food groups in poorer urban areas and townships. In rural areas, access to healthy foods also remains a problem. A national nutrition monitoring system is recommended in order to identify dietary deficiencies in specific population groups.

Psychometric properties of the Social Problem Solving Inventory-Revised Short-Form in a South African population.

Science.gov (United States)

Sorsdahl, Katherine; Stein, Dan J; Myers, Bronwyn

2017-04-01

The Social Problem Solving Inventory-Revised Short-Form (SPSI-R:SF) has been used in several countries to identify problem-solving deficits among clinical and general populations in order to guide cognitive-behavioural interventions. Yet, very few studies have evaluated its psychometric properties. Three language versions of the questionnaire were administered to a general population sample comprising 1000 participants (771 English-, 178 Afrikaans- and 101 Xhosa-speakers). Of these participants, 210 were randomly selected to establish test-retest reliability (70 in each language). Principal component analysis was performed to examine the applicability of the factor structure of the original questionnaire to the South African data. Supplementary psychometric analyses were performed, including internal consistency and test-retest reliability. Collectively, results provide initial evidence of the reliability and validity of the SPSI-R:SF for the assessment of problem solving deficits in South Africa. Further studies that explore how the Afrikaans language version of the SPSI-R:SF can be improved and that establish the predictive validity of scores on the SPSI-R:SF are needed. © 2015 International Union of Psychological Science.

Hand-arm vibration syndrome in South African gold miners.

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

2007-01-01

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

Genetic history of the African Sahelian populations.

Science.gov (United States)

Černý, V; Kulichová, I; Poloni, E S; Nunes, J M; Pereira, L; Mayor, A; Sanchez-Mazas, A

2018-03-01

From a biogeographic perspective, Africa is subdivided into distinct horizontal belts. Human populations living along the Sahel/Savannah belt south of the Sahara desert have often been overshadowed by extensive studies focusing on other African populations such as hunter-gatherers or Bantu in particular. However, the Sahel together with the Savannah bordering it in the south is a challenging region where people had and still have to cope with harsh climatic conditions and show resilient behaviours. Besides exponentially growing urban populations, several local groups leading various lifestyles and speaking languages belonging to three main linguistic families still live in rural localities across that region today. Thanks to several years of consistent population sampling throughout this area, the genetic history of the African Sahelian populations has been largely reconstructed and a deeper knowledge has been acquired regarding their adaptation to peculiar environments and/or subsistence modes. Distinct exposures to pathogens-in particular, malaria-likely contributed to their genetic differentiation for HLA genes. In addition, although food-producing strategies spread within the Sahel/Savannah belt relatively recently, during the last five millennia according to recent archaeological and archaeobotanical studies, remarkable amounts of genetic differences are also observed between sedentary farmers and more mobile pastoralists at multiple neutral and selected loci, reflecting both demographic effects and genetic adaptations to distinct cultural traits, such as dietary habits. © 2017 John Wiley & Sons A/S.

Genetic testing of canine degenerative myelopathy in the South African Boxer dog population

Directory of Open Access Journals (Sweden)

Gareth E. Zeiler

2013-10-01

Full Text Available Canine degenerative myelopathy (DM is a progressive disease process that is diagnosed late in life and mainly affects the pelvic limbs. Factors that make an ante-mortem definitive diagnosis of DM include: an insidious onset and clinical manifestation that mimics other disease processes of the pelvic limbs (hip dysplasia, cranial cruciate ligament rupture, etc. or there may even be concurrent disease processes, old-age onset and lack of reliable diagnostic methods. Until recently, South African dog owners had to submit samples to laboratories overseas for genetic testing in order to confirm an affected dog (homozygous A/A and to aid in the ante-mortem diagnosis of DM. Only affected dogs have been confirmed to manifest the clinical signs of DM. This study aimed to verify whether genetic testing by a local genetic laboratory was possible in order to detect a missense mutation of the superoxide dismutase gene (SOD1 that is implicated in causing the clinical signs of DM. The study also aimed to detect and map the inheritance of this disease process in a local Boxer dog population where the pedigree of the sampled population was known. Venous blood collected from Boxer dogs using a simple random sampling technique. The samples were genotyped for the SOD1:c.118G>A polymorphism. Carrier and affected Boxer dogs were detected. A pedigree that demonstrated the significance of inheriting a carrier or affected state in the population was mapped. The present study concludes that genotyping of the missense mutation in Boxer dogs is possible in South Africa. There are carrier and affected Boxer dogs in the local population, making DM a plausible diagnosis in aged dogs presenting with pelvic limb pathology.

The neglected context: The growing impact of modernity on the South African population and its spiritual, economic and ecological consequences

Directory of Open Access Journals (Sweden)

Klaus N�rnberger

2012-12-01

Full Text Available Humanity seems to be drifting like a rudderless raft towards a cataract. The main factors are the growth of the human population, the escalation of material expectations, the exploding discrepancies between affluent and marginalised population groups and the impact of these growth processes on the natural environment. The modern claim to mastery, ownership and entitlement and its spectacular successes has led to unprecedented power without a concomitant growth in responsibility. In spiritual and cultural terms, modernity undermines all traditional certainties, values and constraints. The South African population is engulfed in a messy transition from African traditionalist, to modern and postmodern assumptions. The most reticent citizens are the least competitive and the most marginalised. The Christian faith, rooted as it is in tradition and geared to spiritual concerns, is no match for the power of the modern mindset. To regain its redemptive relevance, it needs fundamental reconceptualisations. The article closes with a few starting points for such a project.

Age cohort differences in haemoglobin concentrations and associations with physical and cognitive performance among populations of lower income and middle-income countries have not previously been described. We examined the association between these factors among older men and women in rural South Africa. We analysed cross-sectional data from a population-based study of rural South African men and women aged 40 and over (n=4499), with data drawn from questionnaire responses, a cognitive battery, objective physical function tests and blood tests. Anaemia was defined as a haemoglobin concentration age, grip strength, walk speed and a latent cognitive function z-score for men and women separately. We used unadjusted correlations and linear models to adjust for comorbidities and inflammation. In total, 1042 (43.0%) women and 833 (40.1%) men were anaemic. Haemoglobin concentrations were inversely correlated with age for men but not for women; in adjusted analyses, haemoglobin was 0.3 g/dL lower per decade older for men (95% CI 0.2 to 0.4 g/dL). In adjusted analyses, haemoglobin concentration was independently associated with grip strength in women (B=0.391, 95% CI 0.177 to 0.605), but this did not reach significance in men (B=0.266, 95% CI -0.019 to 0.552); no associations were observed between haemoglobin levels and walk speed or cognitive score. Anaemia was prevalent in this study population of middle-aged and older, rural South African adults, but in contrast to high-income countries, it was not associated with poor physical or cognitive function. Our findings need to be replicated in other populations. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

Dissecting the within-Africa ancestry of populations of African descent in the Americas.

Stefflova, Klara; Dulik, Matthew C; Barnholtz-Sloan, Jill S; Pai, Athma A; Walker, Amy H; Rebbeck, Timothy R

2011-01-06

The ancestry of African-descended Americans is known to be drawn from three distinct populations: African, European, and Native American. While many studies consider this continental admixture, few account for the genetically distinct sources of ancestry within Africa--the continent with the highest genetic variation. Here, we dissect the within-Africa genetic ancestry of various populations of the Americas self-identified as having primarily African ancestry using uniparentally inherited mitochondrial DNA. We first confirmed that our results obtained using uniparentally-derived group admixture estimates are correlated with the average autosomal-derived individual admixture estimates (hence are relevant to genomic ancestry) by assessing continental admixture using both types of markers (mtDNA and Y-chromosome vs. ancestry informative markers). We then focused on the within-Africa maternal ancestry, mining our comprehensive database of published mtDNA variation (∼5800 individuals from 143 African populations) that helped us thoroughly dissect the African mtDNA pool. Using this well-defined African mtDNA variation, we quantified the relative contributions of maternal genetic ancestry from multiple W/WC/SW/SE (West to South East) African populations to the different pools of today's African-descended Americans of North and South America and the Caribbean. Our analysis revealed that both continental admixture and within-Africa admixture may be critical to achieving an adequate understanding of the ancestry of African-descended Americans. While continental ancestry reflects gender-specific admixture processes influenced by different socio-historical practices in the Americas, the within-Africa maternal ancestry reflects the diverse colonial histories of the slave trade. We have confirmed that there is a genetic thread connecting Africa and the Americas, where each colonial system supplied their colonies in the Americas with slaves from African colonies they controlled

2009-05-01

South Africa, like many other Southern African countries, has one of the highest HIV infection rates in the world and many individuals consequently receive antiretroviral therapy (ART). However, knowledge regarding (i) the prevalence of functional single nucleotide polymorphisms (SNPs) in pharmacologically relevant genes, and (ii) variance in pharmacotherapy both within and between different populations and ethnic groups is limited. The aim of this study was to determine whether selected polymorphisms in cytochrome P450 (CYP) genes (CYP2B6 and CYP3A4) and the multidrug-resistance 1 (ABCB1) gene underlie altered antiretroviral (ARV) drug response in two South African populations. DNA samples from 182 HIV-positive individuals of Mixed-Ancestry and Xhosa ethnicity on ART were genotyped for the A-392G SNP in CYP3A4, the G516T and A785G SNPs in CYP2B6, and the T-129C, C1236T, G2677T/A and C3435T SNPs in ABCB1. Univariate two-way analysis of variance (ANOVA) testing revealed no apparent effect of ethnicity on immune recovery (in terms of CD4-cell count) in response to ART. Univariate one-way ANOVA testing revealed a discernible effect of genotype on immune recovery in the cases of the T-129C (P=0.03) and G2677A (P<0.01) polymorphisms in the ABCB1 gene. This study serves as a basis for better understanding and possible prediction of pharmacogenetic risk profiles and drug response in individuals and ethnic groups in South Africa.

Population policy in South Africa: a critical perspective.

Science.gov (United States)

Klugman, B

1991-02-01

The argument in this article is that population growth and the concept of balancing resources against population growth is flawed when the context, in this case South Africa, is gross inequalities in resource distribution. The fact is that causes of poverty are located in the social and political structures which give people unequal access to existing resources or international aid. Population trends reflect the mode of production of that society. It is argued that the Malthusian law of population and the theory of demographic transition is ahistorical and inaccurate. The theory does not explain why population growth rates change. In South Africa, fertility reflects lack of control over one's life and poverty. Migrant labor in South Africa undermined normal social institutions and disrupted family life. Government has emphasized a fear of a future population crisis because of resource shortages and a fear of the growing black population. The South African population development program is extracted and discussed. Questions are raised about the theory of demographic transition, the way resource allocation is ascertained, the relationship between resources and population in a specific area, and the relationship between population growth and development in general. The theory of demographic transition is examined and the Western influences which contributed to population growth through requests for changes in sexual mores and the effects of colonization. When demographic transition theory postulates that mortality rates decline with industrialization as a result of access to medical care and an improved diet, it doesn't take into account the discriminatory health care allocation under apartheid, or the displacement of rural people from their land and undermining of the rural peasantry. Separate development has led to inferior schooling and lack of access to skilled employment. In discussing the availability of resources in South Africa, the question is raised as to

Hearing loss in urban South African school children (grade 1 to 3).

Science.gov (United States)

Mahomed-Asmail, Faheema; Swanepoel, De Wet; Eikelboom, Robert H

2016-05-01

This study aimed to describe the prevalence and characteristics of hearing loss in school-aged children in an urban South African population. Children from grade one to three from five schools in the Gauteng Province of South Africa formed a representative sample for this study. All children underwent otoscopic examinations, tympanometry and pure tone screening (25dB HL at 1, 2 and 4kHz). Children who failed the screening test and 5% of those who passed the screening test underwent diagnostic audiometry. A total of 1070 children were screened. Otoscopic examinations revealed that a total of 6.6% ears had cerumen and 7.5% of ears presented with a type-B tympanogram. 24 children (12 male, 12 female) were diagnosed with hearing loss. The overall prevalence of hearing loss was 2.2% with Caucasian children being 2.9 times more (95% confidence interval, 1.2-6.9) likely to have a hearing loss than African children. Hearing loss prevalence in urban South African school-aged children suggest that many children (2.2%) are in need of some form of follow-up services, most for medical intervention (1.2%) with a smaller population requiring audiological intervention (0.4%).

Convergence in fertility of South Africans and Mozambicans in rural South Africa, 1993–2009

Directory of Open Access Journals (Sweden)

Michel Garenne

2013-01-01

Full Text Available Background: Although there are significant numbers of people displaced by war in Africa, very little is known about long-term changes in the fertility of refugees. Refugees of the Mozambican civil war (1977–1992 settled in many neighbouring countries, including South Africa. A large number of Mozambican refugees settled within the Agincourt sub-district, underpinned by a Health and Socio-demographic Surveillance Site (AHDSS, established in 1992, and have remained there. The AHDSS data provide a unique opportunity to study changes in fertility over time and the role that the fertility of self-settled refugee populations plays in the overall fertility level of the host community, a highly relevant factor in many areas of sub-Saharan Africa. Objectives: To examine the change in fertility of former Mozambican self-settled refugees over a period of 16 years and to compare the overall fertility and fertility patterns of Mozambicans to host South Africans. Design: Prospective data from the AHDSS on births from 1993 to 2009 were used to compare fertility trends and patterns and to examine socio-economic factors that may be associated with fertility change. Results: There has been a sharp decline in fertility in the Mozambican population and convergence in fertility patterns of Mozambican and local South African women. The convergence of fertility patterns coincides with a convergence in other socio-economic factors. Conclusion: The fertility of Mozambicans has decreased significantly and Mozambicans are adopting the childbearing patterns of South African women. The decline in Mozambican fertility has occurred alongside socio-economic gains. There remains, however, high unemployment and endemic poverty in the area and fertility is not likely to decrease further without increased delivery of family planning to adolescents and increased education and job opportunities for women.

Unimproved non-descript goats are the main genetic resources used for the development of commercial meat-type breeds of South Africa. Little is known about genetic diversity and the genetics of adaptation of these indigenous goat populations. This study investigated the genetic diversity, population structure and breed relations, linkage disequilibrium, effective population size and persistence of gametic phase in goat populations of South Africa. Three locally developed meat-type breeds of the Boer (n = 33), Savanna (n = 31), Kalahari Red (n = 40), a feral breed of Tankwa (n = 25) and unimproved non-descript village ecotypes (n = 110) from four goat-producing provinces of the Eastern Cape, KwaZulu-Natal, Limpopo and North West were assessed using the Illumina Goat 50K SNP Bead Chip assay. The proportion of SNPs with minor allele frequencies >0.05 ranged from 84.22% in the Tankwa to 97.58% in the Xhosa ecotype, with a mean of 0.32 ± 0.13 across populations. Principal components analysis, admixture and pairwise FST identified Tankwa as a genetically distinct population and supported clustering of the populations according to their historical origins. Genome-wide FST identified 101 markers potentially under positive selection in the Tankwa. Average linkage disequilibrium was highest in the Tankwa (r(2)  = 0.25 ± 0.26) and lowest in the village ecotypes (r(2) range = 0.09 ± 0.12 to 0.11 ± 0.14). We observed an effective population size of 100 kb with the exception of those in Savanna and Tswana populations. This study highlights the high level of genetic diversity in South African indigenous goats as well as the utility of the genome-wide SNP marker panels in genetic studies of these populations. © 2016 Stichting International Foundation for Animal Genetics.

Proportionality in enterprise development of South African towns

Directory of Open Access Journals (Sweden)

Maitland T. Seaman

2012-05-01

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

Brunel mood scale: South African norm study

Directory of Open Access Journals (Sweden)

Charles H Van Wijk

2011-06-01

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

Darwin’s legacy in South African evolutionary biology

Directory of Open Access Journals (Sweden)

S. D. Johnson

2010-02-01

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

Sex determination from the radius and ulna in a modern South African sample.

Science.gov (United States)

Barrier, I L O; L'Abbé, E N

2008-07-18

With a large number of unidentified skeletal remains found in South Africa, the development of population specific osteometric standards is imperative. Forensic anthropologists need to have access to a variety of techniques to establish accurate demographic profiles from complete, fragmentary and/or commingled remains. No research has been done on the forearm of African samples, even though these bones have been shown to exhibit sexual dimorphism. The purpose of this paper is to develop discriminant function formulae to determine sex from the radius and ulna in a South African population. The sample consisted of 200 male and 200 female skeletons from the Pretoria Bone (University of Pretoria) and Raymond A. Dart (Witwatersrand University) collections. Sixteen standard anthropometric measurements were taken from the radius (9) and ulna (7) and subjected to stepwise and direct discriminant function analysis. Distal breadth, minimum mid-shaft diameter and maximum head diameter were the best discriminators of sex for the radius, while minimum mid-shaft diameter and olecranon breadth were selected for the ulna. Classification accuracy for the forearm ranged from 76 to 86%. The radius and ulna can be considered moderate discriminators for determining sex in a South African group. However, it is advised that these formulae are used in conjunction with additional methods to determine sex.

2010-12-01

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

Disaster management and humanitarian logistics – A South African perspective

Directory of Open Access Journals (Sweden)

Wilna L. Bean

2011-11-01

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

Space-time patterns in maternal and mother mortality in a rural South African population with high HIV prevalence (2000-2014): results from a population-based cohort.

Tlou, B; Sartorius, B; Tanser, F

2017-06-03

International organs such as, the African Union and the South African Government view maternal health as a dominant health prerogative. Even though most countries are making progress, maternal mortality in South Africa (SA) significantly increased between 1990 and 2015, and prevented the country from achieving Millennium Development Goal 5. Elucidating the space-time patterns and risk factors of maternal mortality in a rural South African population could help target limited resources and policy guidelines to high-risk areas for the greatest impact, as more generalized interventions are costly and often less effective. Population-based mortality data from 2000 to 2014 for women aged 15-49 years from the Africa Centre Demographic Information System located in the Umkhanyakude district of KwaZulu-Natal Province, South Africa were analysed. Our outcome was classified into two definitions: Maternal mortality; the death of a woman while pregnant or within 42 days of cessation of pregnancy, regardless of the duration and site of the pregnancy, from any cause related to or exacerbated by the pregnancy or its management but not from unexpected or incidental causes; and 'Mother death'; death of a mother whilst child is less than 5 years of age. Both the Kulldorff and Tango spatial scan statistics for regular and irregular shaped cluster detection respectively were used to identify clusters of maternal mortality events in both space and time. The overall maternal mortality ratio was 650 per 100,000 live births, and 1204 mothers died while their child was less than or equal to 5 years of age, of a mortality rate of 370 per 100,000 children. Maternal mortality declined over the study period from approximately 600 per 100,000 live births in 2000 to 400 per 100,000 live births in 2014. There was no strong evidence of spatial clustering for maternal mortality in this rural population. However, the study identified a significant spatial cluster of mother deaths in childhood (p

Genetic affinities of the Siddis of South India: an emigrant population of East Africa.

Gauniyal, Mansi; Chahal, S M S; Kshatriya, Gautam K

2008-06-01

Historical records indicate that the Portuguese brought the African Siddis to Goa, India, as slaves about 500 years ago. Subsequently, the Siddis moved into the interior regions of the state of Karnataka, India, and have remained there ever since. Over time the Siddis have experienced considerable cultural changes because of their proximity to neighboring population groups. To understand the biological consequences of these changes, we studied the Siddis to determine the extent of genetic variation and the contributions from the African, European, and Indian ancestral populations. In the present study we typed the Siddis for 20 polymorphic serological, red cell, and Alu insertion-deletion loci. The overall pattern of phenotype (and genotype) distribution is in accordance with Hardy-Weinberg expectations. Considering the ethnohistorical records and the availability of secondary-source genetic data, we used two data sets in the analysis: one comprising eight serological and red cell enzyme markers with eight population groups and another comprising six Alu insertion-deletion markers with seven tribal groups of South India. The dendrograms generated from these two data sets on the basis of genetic distance analysis between the selected populations of African, European, and Indian descent reveals that the Siddis are closer to the Africans than they are to the South Indian populations. Genetic admixture analysis using a dihybrid model (19 loci) and a trihybrid model (10 loci and 8 loci) shows that the predominant influence comes from the Africans, a lesser contribution from the South Indians, and a slight contribution from the Portuguese. Thus the original composition of the African genes among the Siddis has been diluted to some extent by the contribution from southern Indian population groups. There is no nonrandom association of alleles among a set of 10 genetic marker systems considered in the present study. The demonstration of genetic homogeneity of the Siddis

Morphometric variation in the papionin muzzle and the biochronology of the South African Plio-Pleistocene karst cave deposits.

Gilbert, Christopher C; Grine, Frederick E

2010-03-01

Papionin monkeys are widespread, relatively common members of Plio-Pleistocene faunal assemblages across Africa. For these reasons, papionin taxa have been used as biochronological indicators by which to infer the ages of the South African karst cave deposits. A recent morphometric study of South African fossil papionin muzzle shape concluded that its variation attests to a substantial and greater time depth for these sites than is generally estimated. This inference is significant, because accurate dating of the South African cave sites is critical to our knowledge of hominin evolution and mammalian biogeographic history. We here report the results of a comparative analysis of extant papionin monkeys by which variability of the South African fossil papionins may be assessed. The muzzles of 106 specimens representing six extant papionin genera were digitized and interlandmark distances were calculated. Results demonstrate that the overall amount of morphological variation present within the fossil assemblage fits comfortably within the range exhibited by the extant sample. We also performed a statistical experiment to assess the limitations imposed by small sample sizes, such as typically encountered in the fossil record. Results suggest that 15 specimens are sufficient to accurately represent the population mean for a given phenotype, but small sample sizes are insufficient to permit the accurate estimation of the population standard deviation, variance, and range. The suggestion that the muzzle morphology of fossil papionins attests to a considerable and previously unrecognized temporal depth of the South African karst cave sites is unwarranted.

Publishing South African scholarship in the global academic community

Science.gov (United States)

le Roux, Elizabeth

2015-01-01

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

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

Methods: A total of 24 subjects with type 2 diabetes were administered increasing doses (0 mg/d, 2.5 mg/d, 5 mg/d, 10 mg/d, and 20 mg/d of glibenclamide daily at 2-week intervals. Plasma glibenclamide, glucose, and insulin determinations were performed. Blood sampling times were 0 minute, 30 minutes, 60 minutes, 90 minutes, and 120 minutes (post breakfast sampling and 240 minutes, 270 minutes, 300 minutes, 330 minutes, 360 minutes, and 420 minutes (post lunch sampling on days 14, 28, 42, 56, and 70 for doses of 0 mg, 2.5 mg, 5.0 mg, 10 mg, and 20 mg, respectively. Blood sampling was performed after the steady state was reached.  A total of 24 individuals in the data set contributed to a total of 841 observation records. The PK was analyzed using noncompartmental analysis methods, which were implemented in WinNonLin®, and population PK analysis using NONMEM®. Glibenclamide concentration data were log transformed prior to fitting. Results: A two-compartmental disposition model was selected after evaluating one-, two-, and three-compartmental models to describe the time course of glibenclamide plasma concentration data. The one-compartment model adequately described the data; however, the two-compartment model provided a better fit. The three-compartment model failed to achieve successful convergence. A more complex model, to account for enterohepatic recirculation that was observed in the data, was unsuccessful. Conclusion: In South African diabetic subjects, glibenclamide demonstrates linear PK and was best

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

2012-11-01

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

The South African energy scene

International Nuclear Information System (INIS)

Burger, H.T.

1983-01-01

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

Full Text Available Alcohol abuse accounts for approximately 2.5 million deaths annually and is the third highest risk factor for disease and disability. Alcohol is metabolised by polymorphic enzymes and the status of an individual with respect to alcohol metabolising enzymes may have forensic relevance in post-mortems. Baseline frequencies of gene variants involved in alcohol metabolism need to be established to aid the identification of suitable population-specific polymorphisms to genotype during molecular autopsies. The principal alcohol metabolising enzymes include alcohol dehydrogenase (ADH, aldehyde dehydrogenase (ALDH and cytochrome P450 2E1 (CYP2E1. Six single nucleotide polymorphisms (SNPs – rs1229984G>A and rs2066702C>T in ADH1B, rs671G>A in ALDH2, and rs3813867G>C, rs2031920C>T and rs6413432T>A in CYP2E1 – were genotyped in 150 individuals from four South African populations: Xhosa, Zulu, South African white and South African coloured. Allele frequencies for each SNP in the four population groups were 0–10% for rs1229984A, 2–12% for rs2066702T, 0–2% for rs671A, 1–4% for rs3813867C, 0–1% for rs2031920T and 3–15% for rs6413432A. Haplotype analysis revealed a novel combination of three SNPs in CYP2E1 whose effects on alcohol metabolism need further investigation. Establishment of baseline frequencies adds to our knowledge of genetic variation in alcohol metabolising enzymes and additional research is required to determine the functional significance of this novel CYP2E1 haplotype.

2013-01-01

Food quality, determined by micronutrient content, is a stronger determinant of nutritional status than food quantity. Health concerns resulting from the co-existence of over-nutrition and under-nutrition in low income populations in South Africa have been fully recognized in the last two decades. This study aimed to further investigate dietary adequacy amongst adults in rural KwaZulu-Natal, by determining daily energy and nutrient intakes, and identifying the degree of satisfaction of dietary requirements. Cross-sectional study assessing dietary adequacy from 24-hour dietary recalls of randomly selected 136 adults in Empangeni, KwaZulu-Natal, South Africa. Results are presented for men (n = 52) and women (n = 84) 19-50 and >50 years old. Mean energy intake was greatest in women >50 years (2852 kcal/day) and exceeded Dietary Reference Intake's for both men and women, regardless of age. Mean daily energy intake from carbohydrates was 69% for men and 67% for women, above the Dietary Reference Intake range of 45-65%. Sodium was also consumed in excess, and the Dietary Reference Intakes of vitamins A, B12, C, D, and E, calcium, zinc and pantothenic acid were not met by the majority of the population. Despite mandatory fortification of staple South African foods, micronutrient inadequacies are evident among adults in rural South African communities. Given the excess caloric intake and the rising prevalence of obesity and other non-communicable diseases in South Africa, a focus on diet quality may be a more effective approach to influence micronutrient status than a focus on diet quantity.

Characterization of South African isolates of Fusarium oxysporum f.sp cubense from Cavendish banana

Tom Gordon

2010-04-01

Full Text Available Fusarium wilt, caused by the soil-borne fungus Fusarium oxysporum f.sp. cubense (Foc, is a serious vascular disease of bananas in most subtropical and tropical regions of the world. Twenty-four vegetative compatibility groups (VCGs and three pathogenic races have been identified in Foc, reflecting a relatively high genetic diversity for an asexual fungus. To characterise a South African population of Foc, a collection of 128 isolates from diverse geographic origins were isolated from diseased Cavendish bananas and subjected to VCG analysis and sequencing of the translation elongation factor 1-α (TEF gene region. The presence of mating type genes was also determined using MAT-1 and MAT-2 specific primers. VCG 0120 was established as the only VCG of Foc present in the South African population studied. Only the MAT-2 idiomorph was present in all the local isolates of Foc. A phylogenetic analysis of DNA sequences of the TEF gene region revealed that the South African isolates grouped closely with VCG 0120 isolates from Australia and Asia. These results suggest that the South African population of Foc was most likely introduced in a limited number of events and that it had spread with infected planting material within the country. The presence of only one mating type and the limited diversity in this pathogen render it unlikely to rapidly overcome disease management strategies involving host resistance.

Space-time patterns in maternal and mother mortality in a rural South African population with high HIV prevalence (2000–2014: results from a population-based cohort

Full Text Available Abstract Background International organs such as, the African Union and the South African Government view maternal health as a dominant health prerogative. Even though most countries are making progress, maternal mortality in South Africa (SA significantly increased between 1990 and 2015, and prevented the country from achieving Millennium Development Goal 5. Elucidating the space-time patterns and risk factors of maternal mortality in a rural South African population could help target limited resources and policy guidelines to high-risk areas for the greatest impact, as more generalized interventions are costly and often less effective. Methods Population-based mortality data from 2000 to 2014 for women aged 15–49 years from the Africa Centre Demographic Information System located in the Umkhanyakude district of KwaZulu-Natal Province, South Africa were analysed. Our outcome was classified into two definitions: Maternal mortality; the death of a woman while pregnant or within 42 days of cessation of pregnancy, regardless of the duration and site of the pregnancy, from any cause related to or exacerbated by the pregnancy or its management but not from unexpected or incidental causes; and ‘Mother death’; death of a mother whilst child is less than 5 years of age. Both the Kulldorff and Tango spatial scan statistics for regular and irregular shaped cluster detection respectively were used to identify clusters of maternal mortality events in both space and time. Results The overall maternal mortality ratio was 650 per 100,000 live births, and 1204 mothers died while their child was less than or equal to 5 years of age, of a mortality rate of 370 per 100,000 children. Maternal mortality declined over the study period from approximately 600 per 100,000 live births in 2000 to 400 per 100,000 live births in 2014. There was no strong evidence of spatial clustering for maternal mortality in this rural population. However, the study identified a

Distributed leadership in South African schools: possibilities and constraints

Directory of Open Access Journals (Sweden)

Clarence G Williams

2011-01-01

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

Little research has evaluated the life course drivers of cognitive aging in South Africa. We investigated the relationships of self-rated childhood health and father's occupation during childhood with later-life cognitive function score and whether educational attainment mediated these relationships among older South Africans living in a former region of Apartheid-era racial segregation. Data were from baseline assessments of "Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community" (HAALSI), a population-based study of 5059 men and women aged ≥40 years in 2015 in rural Agincourt sub-district, South Africa. Childhood health, father's occupation during childhood, and years of education were self-reported in study interviews. Cognitive measures assessed time orientation, numeracy, and word recall, which were included in a z-standardized latent cognitive function score variable. Linear regression models adjusted for age, sex, and country of birth were used to estimate the total and direct effects of each childhood risk factor, and the indirect effects mediated by years of education. Poor childhood health predicted lower cognitive scores (total effect = -0.28; 95% CI = -0.35, -0.21, versus good); this effect was not mediated by educational attainment. Having a father in a professional job during childhood, while rare (3% of sample), predicted better cognitive scores (total effect = 0.25; 95% CI = 0.10, 0.40, versus unskilled manual labor, 29% of sample). Half of this effect was mediated by educational attainment. Education was linearly associated with later-life cognitive function score (0.09; 95% CI = 0.09, 0.10 per year achieved). In this post-Apartheid, rural South African context, older adults with poor self-reported childhood health or whose father worked in unskilled manual labor had relatively poor cognitive outcomes. Educational attainment strongly predicted cognitive outcomes, and appeared to be, in part, a mechanism of social

A Founder Mutation in MYO7A Underlies a Significant Proportion of Usher Syndrome in Indigenous South Africans: Implications for the African Diaspora.

Science.gov (United States)

Roberts, Lisa; George, Siddiqah; Greenberg, Jacquie; Ramesar, Raj S

2015-10-01

Research over the past 25 years at the University of Cape Town has led to the identification of causative mutations in 17% of the 1416 families in the Retinal Degenerative Diseases (RDD) biorepository in South Africa. A low rate of mutation detection has been observed in patients of indigenous African origin, hinting at novel genes and mutations in this population. Recently, however, data from our translational research program showed two unrelated indigenous African families with Usher syndrome (USH), with the same homozygous MYO7A mutation. Therefore, the extent to which this mutation contributes toward the disease burden in South Africa was investigated. Cohorts of unrelated indigenous South African probands with different RDD diagnoses were tested for the MYO7A c.6377delC mutation. Familial cosegregation analysis was performed for homozygous probands, clinical data were evaluated, and SNP haplotypes were analyzed. This homozygous MYO7A mutation underlies a remarkable 43% of indigenous African USH cases investigated in this study, the majority of which (60%) were diagnosed clinically with Type 2 USH. All homozygotes shared a common haplotype. This mutation does not appear to cause nonsyndromic vision loss. Of interest is the origin of this common mutation relevant to the Bantu population migration into southern Africa. Further investigation of the phenotype may elucidate the disease biology, and perhaps reveal a larger cohort with the same mutation, with which to assess the impact of environmental and genetic modifiers and evaluate therapeutic trials.

Analysing post-apartheid gender and racial transformation in medical education in a South African province.

Science.gov (United States)

Khan, Taskeen; Thomas, Leena S; Naidoo, Shan

2013-01-24

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. 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. 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. 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 intakes and graduations are in line with the South African

Aggarwal, Shilpa; Taljard, Lian; Wilson, Zane; Berk, Michael

2017-01-01

Background: This report describes the findings of the survey conducted by South African Depression and Anxiety Group (SADAG) in a cohort of disadvantaged South African adolescent scholars in which PHQ-9 teen version was modified and adapted (PHQ-9M) to improve the response rate. Method: PHQ-9M was administered to 2025 secondary students of 35 schools over 2 years in Gauteng Province, South Africa. Results: The mean age was 15.8 years. 23% of respondents scored 9 or above, 26.7% reported suicidal ideations in last month, 21.8% reported lifetime suicide attempts and 9.3% had severe functional impairment. PHQ-9M showed a fair internal consistency and face validity in this study. Conclusion: The PHQ-9M could be useful in conducting surveys in settings of low mental health literacy after further evaluation of its psychometric properties. The high rates of suicidal ideations, suicide attempts, and functional impairment in this population suggest the need for preventive interventions. PMID:28515549

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

Science.gov (United States)

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

2012-09-01

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

Comparative population genetics of the German shepherd dog in South Africa

Directory of Open Access Journals (Sweden)

N. J. Coutts

2010-01-01

Full Text Available Modern breeding practices strive to achieve distinctive phenotypic uniformity in breeds of dogs, but these strategies are associated with the inevitable loss of genetic diversity. Thus, in parallel with the morphological variation displayed by breeds, purebred dogs commonly express genetic defects as a result of the inbreeding associated with artificial selection and the reduction of selection against disease phenotypes. Microsatellite marker analyses of 15 polymorphic canine loci were used to investigate measures of genetic diversity and population differentiation within and between German-bred and South African-bred German shepherd dogs. These data were quantified by comparison with typically outbred mongrel or crossbred dogs. Both the imported and locally-bred German shepherd dogs exhibited similar levels of genetic diversity. The breed is characterised by only a moderate loss of genetic diversity relative to outbred dogs, despite originating from a single founding sire and experiencing extensive levels of inbreeding throughout the history of the breed. Non-significant population differentiation between the ancestral German and derived South African populations indicates sufficient contemporary gene flow between these populations, suggesting that migration resulting from the importation of breeding stock has mitigated the effects of random genetic drift and a population bottleneck caused by the original founder event in South Africa. Significant differentiation between the combined German shepherd dog population and the outbred dogs illustrates the effects of selection and genetic drift on the breed since its establishment just over 100 years ago.

The South African Adventure Tourism Economy: An urban phenomenon

Directory of Open Access Journals (Sweden)

McKay Tracey

2017-09-01

Full Text Available The international adventure tourism literature is remarkably silent on the geographical nature of the industry. This study seeks to provide a geographical analysis of the sector within the context of South Africa. The spatial analysis was undertaken by metropolitan area, secondary towns and small towns, using a dataset of adventure tourism enterprises. It was found that the sector is spatially concentrated and highly urbanised, despite the perception that adventure tourism requires ‘wild’ and outdoor spaces. With many adventure tourism enterprises located in South Africa’s metropolitan areas, it is a hither too unknown sub-sector of the South African urban tourism market. Urban settlements with large populations and a strong general tourism sector form a significant support base for adventure tourism operators. Cape Town is the dominant adventure tourism destination, making it the adventure capital of South Africa. A few small settlements were found to be highly dependent upon the sector for survival.

Overweight and obesity in children and adolescents: The South African problem

Directory of Open Access Journals (Sweden)

Margaretha Viljoen

2012-05-01

Full Text Available Overweight and obesity in children and adolescents are on the increase worldwide.Overweight and obesity increase the risk for the development of non-communicable diseases during childhood and adolescence, and predispose the individual to the development of overweight, obesity,ardiovascular disease, and metabolic and other disorders in adulthood.In Africa the number of overweight or obese children has doubled since 1990. In South Africa,overweight and obesity in children and adolescents are on the increase, but the prevalencevaries with age, gender and population group. These differences are important when intervention programmes and policies are considered. South Africa faces a double burden of disease where undernutrition and overweight or obesity are found in the same populations, in the same households and even in the same children. Malnutrition is a major contributor to the double burden of disease in South African children and adolescents.

Dietary adequacies among South African adults in rural KwaZulu-Natal.

Directory of Open Access Journals (Sweden)

Fariba Kolahdooz

Full Text Available BACKGROUND: Food quality, determined by micronutrient content, is a stronger determinant of nutritional status than food quantity. Health concerns resulting from the co-existence of over-nutrition and under-nutrition in low income populations in South Africa have been fully recognized in the last two decades. This study aimed to further investigate dietary adequacy amongst adults in rural KwaZulu-Natal, by determining daily energy and nutrient intakes, and identifying the degree of satisfaction of dietary requirements. METHODS: Cross-sectional study assessing dietary adequacy from 24-hour dietary recalls of randomly selected 136 adults in Empangeni, KwaZulu-Natal, South Africa. RESULTS: Results are presented for men (n = 52 and women (n = 84 19-50 and >50 years old. Mean energy intake was greatest in women >50 years (2852 kcal/day and exceeded Dietary Reference Intake's for both men and women, regardless of age. Mean daily energy intake from carbohydrates was 69% for men and 67% for women, above the Dietary Reference Intake range of 45-65%. Sodium was also consumed in excess, and the Dietary Reference Intakes of vitamins A, B12, C, D, and E, calcium, zinc and pantothenic acid were not met by the majority of the population. CONCLUSION: Despite mandatory fortification of staple South African foods, micronutrient inadequacies are evident among adults in rural South African communities. Given the excess caloric intake and the rising prevalence of obesity and other non-communicable diseases in South Africa, a focus on diet quality may be a more effective approach to influence micronutrient status than a focus on diet quantity.

Experiences in Developing and Implementing Health Clubs to Reduce Hypertension Risk among Adults in a South African Population in Transition

Directory of Open Access Journals (Sweden)

Thandi R. Puoane

2012-01-01

Full Text Available Chronic noncommunicable diseases (NCDs are increasing substantially as a cause of death and disability in all strata of the South African society, particularly among the urbanised poor. Hypertension is a risk factor for many of these diseases and becoming a burden in a growing population in a Cape Town township, Khayelitsha. To alleviate healthcare demands at clinics in this area, a health club was initiated and community health workers (CHWs were trained to empower community members about NCDs and create public awareness. After training, a health club was initiated. Three months after initiation of the health club, 76 participants had been recruited of whom 22 were regular attenders. New members joined the health club weekly. Anthropometric and blood pressure measurements were taken, and various hypertension topics were covered at the club meetings which included healthy behaviours, such as the benefits of being physically active and eating healthy. Nutrition education sessions based on the South African food-based dietary guidelines were also held. Consequent to the initial group that was established, two more clubs were formed in the area. Health clubs are sustainable and culturally appropriate when facilitated by local people who have an insight and deeper understanding of the culture and environment of the people they serve.

Exposure to lead in South African shooting ranges

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

2017-01-01

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

Trading on extinction: An open-access deterrence model for the South African abalone fishery

Directory of Open Access Journals (Sweden)

Douglas J. Crookes

2016-03-01

Full Text Available South African rhinoceros (e.g.Diceros bicornis and abalone (Haliotis midae have in common that they both are harvested under open-access conditions, are high-value commodities and are traded illegally. The difference is that a legal market for abalone already exists. An open-access deterrence model was developed for South African abalone, using Table Mountain National Park as a case study. It was found that illegal poaching spiked following the closure of the recreational fishery. The resource custodian's objective is to maximise returns from confiscations. This study showed that a legal trade results in a trading on extinction resource trap, with a race for profits, an increase in the probability of detection after a poaching event and the depletion of populations. In contrast with HS Gordon's seminal article (J Polit Econ 1954;62:124-142, profit maximisation does not automatically improve the sustainability of the resource. Under certain conditions (e.g. a legal trade with costly enforcement, profit maximisation may actually deplete abalone populations. The article also has implications for rhino populations, as a legal trade is currently proposed.

Impediments to the adoption of alternative sewerage in South African urban informal settlements.

Science.gov (United States)

Ashipala, N; Armitage, N P

2011-01-01

In recent decades South Africa has witnessed a substantial growth in its urban population. This growth has been accompanied by the mushrooming of informal settlements (shantytowns) flanking more formal development. The lack of adequate urban drainage in many of these informal settlements has resulted in extremely polluted environments which add to the disease burden of the poor people who live there. In many instances, informal settlements in South Africa are established on marginal land that is inherently difficult to service using conventional gravity sewerage. International experience has shown that various alternative wastewater collection systems may present more appropriate ways of providing water-borne sewerage in areas that are difficult to service by conventional means. Alternative sewerage schemes have however had a poor record of success in South African informal settlements - primarily stemming from the implementing agencies' failure to adequately address various social and institutional factors. In this paper, a review of South African experiences with simplified sewerage, settled sewerage and vacuum sewerage in urban informal settlements is used to highlight the key constraints that currently impede the application of these technologies.

Bantjes, Jason R; Kagee, Ashraf; McGowan, Taryn; Steel, Henry

2016-01-01

To investigate the 2-week prevalence of suicidal ideations and their associations to symptoms of posttraumatic stress, depression, and anxiety among South African university students. Data were collected from 1,337 students between May and August 2013. Hierarchical regression analysis was used to investigate the relationship between suicidal ideation and symptoms of posttraumatic stress, depression, and anxiety. Rates of suicidal ideation are higher among university students in South Africa than among the general population of the country and student populations in other parts of the world. Symptoms of depression and exposure to trauma predict suicidal ideation Conclusions: Findings bring into focus the high rates of suicidal ideation among a sample of university students in South African and the need for more research to investigate the psychosocial correlates of this phenomena within the cultural context of the country, especially given the correlation between suicidal ideation and other poor health outcomes.

2012-06-01

A major challenge facing contemporary cancer educators is how to optimize the dissemination of breast cancer prevention and control information to African American women in the Deep South who are believed to be cancer free. The purpose of this research was to provide insight into the breast cancer information-acquisition experiences of African American women in Alabama and Mississippi and to make recommendations on ways to better reach members of this high-risk, underserved population. Focus group methodology was used in a repeated, cross-sectional research design with 64 African American women, 35 years old or older who lived in one of four urban or rural counties in Alabama and Mississippi. Axial-coded themes emerged around sources of cancer information, patterns of information acquisition, characteristics of preferred sources, and characteristics of least-preferred sources. It is important to invest in lay health educators to optimize the dissemination of breast cancer information to African American women who are believed to be cancer free in the Deep South.

The expansion of Africanized honeybees from South America to the southwestern United States in feral population from the southern United States undergoing Africanization. Our microsatellite data showed that (1) the process of Africanization involved both maternal and paternal bidirectional gene flow between European and Africanized honeybees and (2) the panmitic European population was replaced by panmitic mixtures of A. m. scutellata and European genes within 5 years after Africanization. The post-Africanization gene pool (1998-2001) was composed of a diverse array of recombinant classes with a substantial European genetic contribution (mean 25-37%). Therefore, the resulting feral honeybee population of south Texas was best viewed as a hybrid swarm.

Highly polymorphic DNA markers in an Africanized honey bee population in Costa Rica

Directory of Open Access Journals (Sweden)

Jorge Arturo Lobo Segura

2000-06-01

Full Text Available Two genetic markers (the mtDNA COI-COII intergenic region and the microsatellite A7 with high levels of variability in South African and European honey bees were analyzed in wild swarms of Africanized honey bees (Apis mellifera from Costa Rica. Allelic or haplotypic frequencies revealed high levels of genetic variability at these loci in this population. Most of the alleles were African alleles, although some European-derived alleles were also present. Differences in the frequencies of African alleles between African and Africanized samples were minor, which could be explained by founder effects occurring during the introduction of African honey bee populations into South America.Dois marcadores genéticos (a região intergénica mitocondrial COI-COII e o microsatélite A7, com altos níveis de variabilidade em populações de abelhas melíferas da África do Sul e Europa, foram analisados em uma amostra de enxames naturais da Costa Rica. As freqüências alélicas e haplotípicas na amostra africanizada mostraram altos níveis de diversidade nestes loci. A maioria dos alelos são de origem africana, embora alguns alelos de origem européia foram observados. As mudanças nas freqüências dos alelos de origem africana entre as abelhas da África do Sul e as abelhas da população africanizada são de baixa magnitude e podem ter sido causadas pelo efeito fundador que ocorreu na introdução da abelha africana na América do Sul.

Modelling the South African fruit export infrastructure: A case study

2006-06-01

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

The allelic distribution of -308 Tumor Necrosis Factor-alpha gene polymorphism in South African women with cervical cancer and control women

International Nuclear Information System (INIS)

Govan, Vandana A; Constant, Debbie; Hoffman, Margaret; Williamson, Anna-Lise

2006-01-01

Cervical cancer is due to infection with specific high-risk types of human papillomavirus (HPV). Although the incidence of genital HPV infection in various population groups is high, most of these regress without intervention. Investigating genetic host factors and cellular immune responses, particularly cytokines, could help to understand the association between genital HPV infection and carcinogenesis. The tumor necrosis factor alpha (TNF-α) cytokine plays an important role in all stages of cervical cancer and has the ability to induce the regression of human tumors. Therefore the aim of the study was to investigate the allelic distribution of -308 TNF-α gene polymorphism in South African women with cervical cancer compared to control women. Included in our study were women with histologically proven cancer of the cervix (n = 244) and hospital-based controls (n = 228). All patients and controls were from mixed race and black population groups in South Africa. The detection of a bi-allelic -308 (A/G) polymorphism in the promoter region of TNF-α was investigated using the amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) technique. The distributions of the allelic frequencies were stratified in both patients and controls into two South African ethnic population groups. In this study we observed no association between the distribution of -308 TNF-α polymorphism and the risk of developing cervical cancer even after combining the data from the two ethnic populations (X 2 = 2.26). In addition, using the chi-squared test we found no significant association between the known risk factors for cervical cancer and the allele distribution of -308 TNF-α. However, the frequency of the rare high-producing allele -308A of TNF-α was significantly lower in the South African population when compared to Caucasians and Chinese population groups. We demonstrated no association between -308 TNF-α polymorphism and the risk of cervical cancer among two

Depression in the South African workplace

Directory of Open Access Journals (Sweden)

Marthinus P. Stander

2016-05-01

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

Governance, ‘sovereignty-state-territory triad’, human population migration and xenophobia in (South Africa

Directory of Open Access Journals (Sweden)

Johannes Tsheola

2015-12-01

Full Text Available This article seeks to examine the association of the concept of governance of international relations and, by implication, human population migration, through the rigid practices of “sovereignty-state-territory triad” with the fomentation and exacerbation of societal stereotypes, attitudes and perceptions of xenophobia in Africa, in general, and South Africa, in particular. Ascriptions of the majority of population migration as “international” affirms the centrality of the operationalisation of the “sovereignty-state-territory triad” in understanding the fragmentary constructions of societal attitudes and perceptions of people resident in distinct geopolitical entities ascribed as national territories. State and non-state governance entrapments with this triad perpetuate societal stereotypes that are in concurrence with bordered-territories where populations described as citizens are stimulated to protect endowments and resources of the land against the perceived destruction associated with the conduct of the out-groups. Unsurprisingly, the theorisation of human population migration has equally been intricately involved with environmental conservation and securitisation of biodiversity that enables land dispossession of the vulnerable sections of the population through the Western economic narratives of “Peace Parks”. Simultaneously in Southern Africa, the concept of African Renaissance, inescapably embedded with “cooperation and conflict” at all scales, has offered a buzzword to be realised through “Peace Parks” that have evidently failed to deliver reaffirmation of African cultures, continental emancipation and democratisation. The preeminence of societal stereotypes, attitudes and perceptions of xenophobia and violent abuses of African immigrants in South Africa provides vivid illustrations of the inconsistencies and non-linearity of concepts such as African Renaissance and “Peace Parks”. This article asserts that

The Frequency of Cytochrome P450 2E1 Polymorphisms in Black South Africans

Directory of Open Access Journals (Sweden)

Paul K. Chelule

2006-01-01

Full Text Available Polymorphisms in the promoter region of the Cytochrome P4502E1 (CYP2E1 gene reportedly modify the metabolic activity of CYP2E1 enzyme, and have been associated with increased susceptibility to squamous cell carcinoma (SCC of the oesophagus in high prevalence areas such as China. To assess the frequency of these polymorphisms in Black South Africans, a population with a high incidence of oesophageal SCC, this study examined genomic DNA from 331 subjects for restriction fragment length polymorphisms in the CYP2E1 (RsaI and PstI digestion. The frequency of the CYP2E1 c1/c1 and c1/c3 genotypes was 95% and 5% respectively. The frequency of the CYP2E1 allele distribution was found to be markedly different between Chinese and South African populations; hence it is important to place racial differences into consideration when proposing allelic variants as genetic markers for cancer.

An overview of South African psychology.

Science.gov (United States)

Cooper, Saths; Nicholas, Lionel

2012-01-01

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

Cash flow forecast for South African firms

Directory of Open Access Journals (Sweden)

Yun Li

2015-06-01

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

There is a known heavy burden of hazardous drinking and its associated health risks among black South African MSM; however, no study to date has identified risk factors for hazardous drinking among this nor any other African MSM population. A cross-sectional survey was conducted among 480 black South African MSM recruited using respondent-driven sampling. All analyses were adjusted using an RDS II estimator. Multivariable logistic regression was used to assess the relationship between demographic characteristics, psychosocial factors, behavioral attributes and hazardous drinking. More than half of the men (62%, 95%CI=56%-68%) screened positive as hazardous drinkers. In multivariable analyses, living in a township (versus the city of Pretoria) (aOR=1.9, 95%CI=1.2-3.1, pchild (aOR=2.6, 95%CI=1.1-6.4, p=.03), having anxiety (aOR=5.4, 95%CI=1.2-24.3, p=.03), and social network drinking behavior (aOR=5.4, 95%CI=1.2-24.3, p=.03) were positively associated with hazardous drinking. Being sexually attracted only to men (aOR=0.3, 95%CI=0.1-0.8, p=.01) was negatively associated with hazardous drinking. Hazardous drinking is highly prevalent among black South African MSM. Multiple indicators of social vulnerability were identified as independent determinants of hazardous drinking. These findings are of heightened concern because these health problems often work synergistically to increase risk of HIV infection and should be taken into consideration by efforts aimed at reducing hazardous drinking among this critical population.

A chronotype comparison of South African and Dutch marathon runners: The role of scheduled race start times and effects on performance.

Science.gov (United States)

Henst, Rob H P; Jaspers, Richard T; Roden, Laura C; Rae, Dale E

2015-01-01

Recently, a high prevalence of morning-types was reported among trained South African endurance athletes. Proposed explanations for this observation were that either the chronotype of these athletes is better suited to coping with the early-morning start times of endurance events in South Africa; or habitual early waking for training or endurance events may have conditioned the athletes to adapt and become morning-types. The South African endurance athletes also had earlier chronotypes compared to a control population of less active individuals, suggesting that individuals who are more physically active may have earlier chronotypes. However, since both the South African athlete and control groups showed an overrepresentation of morning-types compared to European and American populations, the South African climate may in part have explained this bias towards morningness. Given the latitude and climate differences between South Africa and the Netherlands, and that South African marathons typically start at about 06:30 while those in the Netherlands start later (±11:00), comparison of South African and Dutch marathon runners and active controls would allow for simultaneous assessment of the effects of marathon start time, degree of physical activity and climate on chronotype. Therefore, the primary aims of this study were: (i) to assess the effect of marathon start time on chronotype in marathon runners and (ii) to determine the extent to which either degree of physical activity or climate might explain the bias towards morningness observed in South African athletes and controls. A secondary aim was to determine whether any relationships exist between chronotype, PERIOD3 (PER3) variable number tandem repeat (VNTR) polymorphism genotype, habitual training habits and marathon performance. Trained male marathon runners from South Africa (n = 95) and the Netherlands (n = 90), and active but non-competitive male controls from South Africa (n = 97) and the

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

International Nuclear Information System (INIS)

1984-07-01

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

Impediments to the successful reconstruction of African immigrant teachers' professional identities in South African schools

Directory of Open Access Journals (Sweden)

Saloshna Vandeyar

2014-06-01

Full Text Available The purpose of this study was to explore difficulties and challenges that confront African immigrant teachers as they attempt to reconstruct their professional identities in South African schools. The study was qualitative in nature and utilized narrative inquiry and the case study approach. Data-gathering techniques included a mix of semi-structured interviews, observations, focus group interviews, field notes and researcher journals. Data were analysed using grounded theory and content analysis methods. Findings of the study revealed that immigration status, employment status, attitudes of indigenous learners and holding on to former culture or way of knowing due to lack of induction or mentoring, were impediments to the successful reconstruction of African immigrant teachers' professional identities in South African schools.

A genomic portrait of haplotype diversity and signatures of selection in indigenous southern African populations.

Directory of Open Access Journals (Sweden)

Emile R Chimusa

2015-03-01

Full Text Available We report a study of genome-wide, dense SNP (∼ 900K and copy number polymorphism data of indigenous southern Africans. We demonstrate the genetic contribution to southern and eastern African populations, which involved admixture between indigenous San, Niger-Congo-speaking and populations of Eurasian ancestry. This finding illustrates the need to account for stratification in genome-wide association studies, and that admixture mapping would likely be a successful approach in these populations. We developed a strategy to detect the signature of selection prior to and following putative admixture events. Several genomic regions show an unusual excess of Niger-Kordofanian, and unusual deficiency of both San and Eurasian ancestry, which were considered the footprints of selection after population admixture. Several SNPs with strong allele frequency differences were observed predominantly between the admixed indigenous southern African populations, and their ancestral Eurasian populations. Interestingly, many candidate genes, which were identified within the genomic regions showing signals for selection, were associated with southern African-specific high-risk, mostly communicable diseases, such as malaria, influenza, tuberculosis, and human immunodeficiency virus/AIDs. This observation suggests a potentially important role that these genes might have played in adapting to the environment. Additionally, our analyses of haplotype structure, linkage disequilibrium, recombination, copy number variation and genome-wide admixture highlight, and support the unique position of San relative to both African and non-African populations. This study contributes to a better understanding of population ancestry and selection in south-eastern African populations; and the data and results obtained will support research into the genetic contributions to infectious as well as non-communicable diseases in the region.

Pamidronate treatment for osteogenesis imperfecta in black South Africans.

Science.gov (United States)

Henderson, B D; Isaac, N; Mabele, O; Khiba, S; Nkayi, A; Mokoena, T

2016-05-25

Osteogenesis imperfecta is a heritable disorder of bone connective tissue. Type III has a high incidence in the black pop-ulation of South Africa. Affected people experience numerous fractures, bone pain and progressive disability. Until the introduction of bisphosphonates to reduce fracture incidence, treatment revolved around orthopaedic and supportive care. Objective. To assess the subjective attitude of patients towards pamidronate treatment. Thirty black patients with osteogenesis imperfecta type III treated at Universitas Hospital were approached and 26 were included in this study. Patients or their parents were interviewed using a standardised researcher-administered questionnaire, either in person or by telephone. Most patients reported a reduction in symptoms, a feeling of increased wellbeing, increased strength and rated the pamidronate treatment highly. The intravenous route of administration and the side-effects experienced were bearable. Overall all patients would recommend this treatment to other affected persons. This is first study to look at bisphosphonate treatment for osteogenesis imperfecta type III in black South Africans. The treatment is well tolerated and highly rated by the patients. Reported improvements and side-effects are similar to those reported in other populations. Using this form of treatment in this population is supported by these findings.

Public health implications of changing patterns of recruitment into the South African mining industry, 1973-2012: a database analysis.

Ehrlich, Rodney; Montgomery, Alex; Akugizibwe, Paula; Gonsalves, Gregg

2017-08-03

The triple epidemic of silicosis, tuberculosis and HIV infection among migrant miners from South Africa and neighbouring countries who have worked in the South African mining industry is currently the target of regional and international control efforts. These initiatives are hampered by a lack of information on this population. This study analysed the major South African mining recruitment database for the period 1973 to 2012 by calendar intervals and demographic and occupational characteristics. Changes in area of recruitment were mapped using a geographic information system. The database contained over 10 million contracts, reducible to 1.64 million individuals. Major trends relevant to health projection were a decline in gold mining employment, the major source of silicosis; increasing recruitment of female miners; and shifts in recruitment from foreign to South African miners, from the Eastern to the Northwestern parts of South Africa, and from company employees to contractors. These changes portend further externalisation of the burden of mining lung disease to home communities, as miners, particularly from the gold sector, leave the industry. The implications for health, surveillance and health services of the growing number of miners hired as contractors need further research, as does the health experience of female miners. Overall, the information in this report can be used for projection of disease burden and direction of compensation, screening and treatment services for the ex-miner population throughout Southern Africa.

Job-hopping amongst African Black senior management in South Africa

Directory of Open Access Journals (Sweden)

Khanyile C.C. Nzukuma

2011-11-01

Research purpose: The study focused on understanding why African Black senior managers have a propensity to change jobs and how organisations can resolve the trend. Motivation for the study: To develop a better understanding of the push and pull factors for African Black senior managers in organisations. Research design, approach and method: The research was conducted in two phases, namely as part of a qualitative study and a quantitative study: Creswell (2003 refers to this approach as triangulation. The target population was African Black senior managers on the database of a large Human Resources Consultancy, The South African Rewards Association and the Association of Black Actuaries and Investment Professionals (ABSIP (n = 2600. A total of 208 usable responses were received. Main findings: The main findings and contribution to the field of study was that African Black senior managers do not trust organisations with their career development. They would rather take control of their own career development by moving from organisation to organisation to build their repertoire of skills and competence. They want to be in charge of their careers. This finding has profound implications for organisations employing African Black managers in the senior cadre. Practical/managerial implications: Managers of African Black senior managers need to create attractive employee value propositions that address the main findings. Contribution/value-add: The research shows that African Black senior managers generally seek corporate environments that encourage a sense of belonging and with a clear career growth plan.

Population Genomics of sub-saharan Drosophila melanogaster: African diversity and non-African admixture.

Directory of Open Access Journals (Sweden)

John E Pool

Full Text Available Drosophila melanogaster has played a pivotal role in the development of modern population genetics. However, many basic questions regarding the demographic and adaptive history of this species remain unresolved. We report the genome sequencing of 139 wild-derived strains of D. melanogaster, representing 22 population samples from the sub-Saharan ancestral range of this species, along with one European population. Most genomes were sequenced above 25X depth from haploid embryos. Results indicated a pervasive influence of non-African admixture in many African populations, motivating the development and application of a novel admixture detection method. Admixture proportions varied among populations, with greater admixture in urban locations. Admixture levels also varied across the genome, with localized peaks and valleys suggestive of a non-neutral introgression process. Genomes from the same location differed starkly in ancestry, suggesting that isolation mechanisms may exist within African populations. After removing putatively admixed genomic segments, the greatest genetic diversity was observed in southern Africa (e.g. Zambia, while diversity in other populations was largely consistent with a geographic expansion from this potentially ancestral region. The European population showed different levels of diversity reduction on each chromosome arm, and some African populations displayed chromosome arm-specific diversity reductions. Inversions in the European sample were associated with strong elevations in diversity across chromosome arms. Genomic scans were conducted to identify loci that may represent targets of positive selection within an African population, between African populations, and between European and African populations. A disproportionate number of candidate selective sweep regions were located near genes with varied roles in gene regulation. Outliers for Europe-Africa F(ST were found to be enriched in genomic regions of locally

The European population showed different levels of diversity reduction on each chromosome arm, and some African populations displayed chromosome arm-specific diversity reductions. Inversions in the European sample were associated with strong elevations in diversity across chromosome arms. Genomic scans were conducted to identify loci that may represent targets of positive selection within an African population, between African populations, and between European and African populations. A disproportionate number of candidate selective sweep regions were located near genes with varied roles in gene regulation. Outliers for Europe-Africa FST were found to be enriched in genomic regions of locally elevated cosmopolitan

Intrinsic rewards and work engagement in the South African retail industry

Directory of Open Access Journals (Sweden)

Sara Jacobs

2014-11-01

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

South African teachers’ exposure to workplace bullying

Directory of Open Access Journals (Sweden)

Corene de Wet

2013-12-01

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

Comparison of telomere length in black and white teachers from South Africa: the sympathetic activity and ambulatory blood pressure in Africans study.

Telomere length is a marker of biological aging that has been linked to cardiovascular disease risk. The black South African population is witnessing a tremendous increase in the prevalence of cardiovascular disease, part of which might be explained through urbanization. We compared telomere length between black South Africans and white South Africans and examined which biological and psychosocial variables played a role in ethnic difference in telomere length. We measured leukocyte telomere length in 161 black South African teachers and 180 white South African teachers aged 23 to 66 years without a history of atherothrombotic vascular disease. Age, sex, years having lived in the area, human immunodeficiency virus (HIV) infection, hypertension, body mass index, dyslipidemia, hemoglobin A1c, C-reactive protein, smoking, physical activity, alcohol abuse, depressive symptoms, psychological distress, and work stress were considered as covariates. Black participants had shorter (median, interquartile range) relative telomere length (0.79, 0.70-0.95) than did white participants (1.06, 0.87-1.21; p < .001), and this difference changed very little after adjusting for covariates. In fully adjusted models, age (p < .001), male sex (p = .011), and HIV positive status (p = .023) were associated with shorter telomere length. Ethnicity did not significantly interact with any covariates in determining telomere length, including psychosocial characteristics. Black South Africans showed markedly shorter telomeres than did white South African counterparts. Age, male sex, and HIV status were associated with shorter telomere length. No interactions between ethnicity and biomedical or psychosocial factors were found. Ethnic difference in telomere length might primarily be explained by genetic factors.

Understanding the Association of Type 2 Diabetes Mellitus in Breast Cancer Among African American and European American Populations in South Carolina.

Science.gov (United States)

Samson, Marsha E; Adams, Swann Arp; Orekoya, Olubunmi; Hebert, James R

2016-09-01

In South Carolina, the co-occurrence of diabetes mellitus (DM) and breast cancer (BrCA) is much more prevalent among African American populations than among European American populations. The underlying relationship between diabetes and breast cancer may influence breast cancer survival. The purpose of this investigation is to examine the effect of diabetes on developing breast cancer and to reduce racial disparities in breast cancer outcomes. Study participants included women of European American (EA) and African American (AA) ethnicity from both the Medicaid ICD-9 designations and the South Carolina Central Cancer Registry (SCCCR). A historical prospective cohort design was used to determine the risk of developing breast cancer among women of different ethnicities with and without DM. The chi-square test was used to determine the significance of the association; the logistic model was used to assess the relationship between breast cancer and other factors among EA and AA women. Menopause may have protective properties for AA compared to EA women. AA women have twice the odds of not surviving from each breast cancer stage compared to EA women with respect to their breast cancer stage. Adherence to diabetes medication may contribute to lower breast cancer death in EA. This study illustrates the discrepancy between EA and AA women in terms of breast cancer survival. AA women bear a higher disease burden than EA women. To create ethnic-appropriate public health policies, it is imperative that we understand the effect of comorbidities on breast cancer and how we can prevent them from occurring.

2016-01-01

Large genome-wide association (GWA) studies of European ancestry individuals have identified multiple genetic variants influencing iron status. Studies on the generalizability of these associations to African ancestry populations have been limited. These studies are important given interethnic differences in iron status and the disproportionate burden of iron deficiency among African ancestry populations. We tested the associations of 20 previously identified iron status-associated single nucleotide polymorphisms (SNPs) in 628 Kenyans, 609 Tanzanians, 608 South Africans and 228 African Americans. In each study, we examined the associations present between 20 SNPs with ferritin and haemoglobin, adjusting for age, sex and CRP levels. In the meta analysis including all 4 African ancestry cohorts, we replicated previously reported associations with lowered haemoglobin concentrations for rs2413450 (β = -0.19, P = 0.02) and rs4820268 (β = -0.16, P = 0.04) in TMPRSS6. An association with increased ferritin concentrations was also confirmed for rs1867504 in TF (β = 1.04, P = ancestry individuals. While there is now evidence for the associations of a number of genetic variants with iron status in both European and African ancestry populations, the considerable lack of concordance highlights the importance of continued ancestry-specific studies to elucidate the genetic underpinnings of iron status in ethnically diverse populations.

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

Science.gov (United States)

Mhlongo, T P

1999-09-01

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

Understanding HIV Transmission Risk Behavior Among HIV-Infected South Africans Receiving Antiretroviral Therapy: An Information—Motivation—Behavioral Skills Model Analysis

2014-01-01

The current study applied the Information—Motivation—Behavioral Skills (IMB) model (J. D. Fisher & Fisher, 1992; W. A. Fisher & Fisher, 1993) to identify factors associated with HIV transmission risk behavior among HIV-infected South Africans receiving antiretroviral therapy (ART), a population of considerable significance for curtailing, or maintaining, South Africa’s generalized HIV epidemic. HIV prevention information, HIV prevention motivation, HIV prevention behavioral skills, and HIV transmission risk behavior were assessed in a sample of 1,388 South Africans infected with HIV and receiving ART in 16 clinics in KwaZulu-Natal, South Africa. Results confirmed the assumptions of the IMB model and demonstrated that HIV prevention information and HIV prevention motivation work through HIV prevention behavioral skills to affect HIV transmission risk behavior in this population. Subanalyses confirmed these relationships for HIV transmission risk behavior overall and for HIV transmission risk behavior with partners perceived to be HIV-negative or HIV-status unknown. A consistent pattern of gender differences showed that for men, HIV prevention information and HIV prevention motivation may have direct links with HIV preventive behavior, while for women, the effects of HIV prevention information and HIV prevention motivation work through HIV prevention behavioral skills to affect HIV preventive behavior. These IMB model-based findings suggest directions for HIV prevention interventions with South African men and women living with HIV and on ART as an important component of overall strategies to contain South Africa’s generalized HIV epidemic.

International positioning of South African electricity prices and commodity differentiated pricing

Directory of Open Access Journals (Sweden)

George A. Thopila

2013-07-01

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

Association analysis of two single-nucleotide polymorphisms of the RELN gene with autism in the South African population

KAUST Repository

Sharma, Jyoti Rajan

2013-02-01

Background: Autism (MIM209850) is a neurodevelopmental disorder characterized by a triad of impairments, namely impairment in social interaction, impaired communication skills, and restrictive and repetitive behavior. A number of family and twin studies have demonstrated that genetic factors play a pivotal role in the etiology of autistic disorder. Various reports of reduced levels of reelin protein in the brain and plasma in autistic patients highlighted the role of the reelin gene (RELN) in autism. There is no such published study on the South African (SA) population. Aims: The aim of the present study was to find the genetic association of intronic rs736707 and exonic rs362691 (single-nucleotide polymorphisms [SNPs] of the RELN gene) with autism in a SA population. Methods: Genomic DNA was isolated from cheek cell swabs from autistic (136) as well as control (208) subjects. The TaqMan ® Real-Time polymerase chain reaction and genotyping assay was utilized to determine the genotypes. Results: A significant association of SNP rs736707, but not for SNP rs362691, with autism in the SA population is observed. Conclusion: There might be a possible role of RELN in autism, especially for SA populations. The present study represents the first report on genetic association studies on the RELN gene in the SA population. © 2013, Mary Ann Liebert, Inc.

The African wild dog (Lycaon pictus) is an endangered African canid threatened by severe habitat fragmentation, human-wildlife conflict, and infectious disease. A highly specialized carnivore, it is distinguished by its social structure, dental morphology, absence of dewclaws, and colorful pelage. We sequenced the genomes of two individuals from populations representing two distinct ecological histories (Laikipia County, Kenya and KwaZulu-Natal Province, South Africa). We reconstructed population demographic histories for the two individuals and scanned the genomes for evidence of selection. We show that the African wild dog has undergone at least two effective population size reductions in the last 1,000,000 years. We found evidence of Lycaon individual-specific regions of low diversity, suggestive of inbreeding or population-specific selection. Further research is needed to clarify whether these population reductions and low diversity regions are characteristic of the species as a whole. We documented positive selection on the Lycaon mitochondrial genome. Finally, we identified several candidate genes (ASIP, MITF, MLPH, PMEL) that may play a role in the characteristic Lycaon pelage.

Morphometric variations of the 7th cervical vertebrae of Zulu, White, and Colored South Africans.

Science.gov (United States)

Kibii, Job M; Pan, Rualing; Tobias, Phillip V

2010-05-01

The 7th cervical vertebrae of 240 cadavers of South African Zulu, White, and Colored population groups were examined to determine morphometric variation. White and Colored females had statistically significant narrower cervical anteroposterior diameters than their male counterparts, whereas no statistically significant difference between sexes of the Zulu population group was observed in this variable. In addition, although Zulu and Colored females had statistically significant narrower cervical transverse diameters than their male counterparts, there was no statistically significant variation between South African white males and females in this respect. The findings indicate that sexual dimorphism is more apparent in the vertebral centrum, across the three population groups, where males had significantly larger dimensions in centrum anteroposterior diameter, height, and width than their female counterparts. The study further reveals that sexual dimorphism is more apparent when one compares aspects of the 7th cervical vertebra between sexes within the same population group. Overall, the dimensions of the various variates of the vertebra are substantially smaller in women than in men. The smaller dimensions, particularly of the centrum, may be the result of lower skeletal mass in women and render them more vulnerable to fractures resulting from compression forces. 2010 Wiley-Liss, Inc.

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

Science.gov (United States)

Carstens, Pieter; Stevens, Philip

2016-01-01

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

Cutting the apron strings: the South African experience of decolonisation

Directory of Open Access Journals (Sweden)

G E Devenish

2013-12-01

Full Text Available Decolonisation is a recurring constitutional and political theme in the process of change and reform in South Africa’s history during the 20th century. The constitutional emancipation of the erstwhile Union of South Africa and the subsequent internal decolonisation of designated black ethnic population and cultural groups, are two kindred processes which have interesting similarities, but also important differences. The former involved British Imperialism, the latter involved Afrikaner Nationalism and African Nationalism. The former was a natural, legitimate and spontaneous process, the latter was an artificial process that was induced by Afrikaner Nationalism, that was spurned internationally and domestically by the the international community of nations and indigenous people of South Africa respectively. The article examines the legitimacy of the process of the decolonisation of the Union of South Africa resulting in its independence, followed by the adoption of a republican form of government. In contrast, a comparison is made with the controversial and questionable evolution of the Bantustans, which emerged out of the erstwhile native reserves, a stratagem designed in effect to thwart the liberation struggle for a truly democratic form of government for all the people of South Africa. This pseudo decolonisation was an analogous process to that of genuine decolonisation. The former involved political fragmentation, whatever it was designated, that in effect, denied to the indigenous people, freedom and liberation for decades. As an odyssey it was a very protracted and painful process. Ultimately, in a belated and circuitous manner, after the inordinate suffering and oppression of South Africa’s indigenous people, a genuine democracy in a unified and consolidated state for all the people of South Africa was to transpire. This was liberation and not decolonisation, and was the final stage in the historic and traumatic process for South

Genetic analysis of three South African horse breeds

Directory of Open Access Journals (Sweden)

E.G. Cothran

1998-07-01

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

Urban Ecology in Cape Town: South African Comparisons and Reflections

Directory of Open Access Journals (Sweden)

Sarel S. Cilliers

2012-09-01

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

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

Science.gov (United States)

Braude, Hillel David

2009-06-01

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

Astronomy for teachers: A South African Perspective

Science.gov (United States)

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

2015-08-01

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

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

Directory of Open Access Journals (Sweden)

Evode

2015-12-01

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

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

Public health implications of changing patterns of recruitment into the South African mining industry, 1973–2012: a database analysis

Directory of Open Access Journals (Sweden)

Rodney Ehrlich

2017-08-01

Full Text Available Abstract Background The triple epidemic of silicosis, tuberculosis and HIV infection among migrant miners from South Africa and neighbouring countries who have worked in the South African mining industry is currently the target of regional and international control efforts. These initiatives are hampered by a lack of information on this population. Methods This study analysed the major South African mining recruitment database for the period 1973 to 2012 by calendar intervals and demographic and occupational characteristics. Changes in area of recruitment were mapped using a geographic information system. Results The database contained over 10 million contracts, reducible to 1.64 million individuals. Major trends relevant to health projection were a decline in gold mining employment, the major source of silicosis; increasing recruitment of female miners; and shifts in recruitment from foreign to South African miners, from the Eastern to the Northwestern parts of South Africa, and from company employees to contractors. Conclusions These changes portend further externalisation of the burden of mining lung disease to home communities, as miners, particularly from the gold sector, leave the industry. The implications for health, surveillance and health services of the growing number of miners hired as contractors need further research, as does the health experience of female miners. Overall, the information in this report can be used for projection of disease burden and direction of compensation, screening and treatment services for the ex-miner population throughout Southern Africa.

Determinants of relative skeletal maturity in South African children.

Science.gov (United States)

Hawley, Nicola L; Rousham, Emily K; Johnson, William; Norris, Shane A; Pettifor, John M; Cameron, Noël

2012-01-01

The variation of skeletal maturity about chronological age is a sensitive indicator of population health. Age appropriate or advanced skeletal maturity is a reflection of adequate environmental and social conditions, whereas delayed maturation suggests inadequate conditions for optimal development. There remains a paucity of data, however, to indicate which specific biological and environmental factors are associated with advancement or delay in skeletal maturity. The present study utilises longitudinal data from the South African Birth to Twenty (Bt20) study to indentify predictors of relative skeletal maturity (RSM) in early adolescence. A total of 244 black South African children (n=131 male) were included in this analysis. Skeletal maturity at age 9/10 years was assessed using the Tanner and Whitehouse III RUS technique. Longitudinal data on growth, socio-economic position and pubertal development were entered into sex-specific multivariable general linear regression models with relative skeletal maturity (skeletal age-chronological age) as the outcome. At 9/10 years of age males showed an average of 0.66 years delay in skeletal maturation relative to chronological age. Females showed an average of 1.00 year delay relative to chronological age. In males, being taller at 2 years (pdetermining the rate of skeletal maturation during childhood independently of current stature. Copyright © 2011 Elsevier Inc. All rights reserved.

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

Directory of Open Access Journals (Sweden)

Shantelle Weber

2015-11-01

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

Do international economic developments affect the South African economy?

Directory of Open Access Journals (Sweden)

JA Swanepoel

2014-07-01

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

Reduction of in utero lead exposures in South African populations: Positive impact of unleaded petrol.

Directory of Open Access Journals (Sweden)

Halina B Röllin

Full Text Available Prenatal exposure to lead (Pb has been shown to have negative and irreversible health impacts on foetal and early childhood development, affecting morbidity and mortality in adulthood. This study aimed to assess in utero Pb exposure, examine birth outcomes, and identify confounding factors in the large cohort of South African population, following the legislated removal of Pb from petrol.Lead was measured in the maternal blood, urine and cord blood using Inductive Coupled Plasma Mass spectrometry (ICP-MS. The statistical analyses included Spearman's correlation, Wilcoxon rank sum (Mann Whitney, Kruskal-Wallis rank tests and multivariate linear regression.Overall, the geometric mean (GM of Pb in maternal blood (PbB was 1.32 μg/dL (n = 640; 95% CI, 1.24-1.40. In the subset cohort, the GM of paired maternal PbB and cord blood (PbC was 1.73 μg/dL (n = 350; 95% CI, 1.60-1.86 and 1.26 μg/dL (n = 317; 95% CI, 1.18-1.35, respectively with a positive correlation between the log PbB and the log PbC (rho = 0.65, p = <0.001. Birth outcomes showed geographical differences in the gestational age (p<0.001, birth length (p = 0.028 and head circumference (p<0.001, Apgar score at 5 min (p<0.001 and parity (p<0.002. In female neonates, a positive association was found between PbC and head circumference (rho = 0.243; p<0.016. The maternal PbB levels were positively correlated with race, educational status, water sources, cooking fuels and use of pesticides at home.This study has demonstrated not only the positive impact that the introduction of unleaded petrol and lead-free paint has had on in utero exposure to Pb in South Africa, but has also contributed new data on the topic, in a region where such data and scientific investigations in this field are lacking. Future research should evaluate if similar effects can be detected in young children and the adult population.

Progression of the epidemiological transition in a rural South African setting: findings from population surveillance in Agincourt, 1993–2013

Directory of Open Access Journals (Sweden)

Chodziwadziwa W. Kabudula

2017-05-01

Full Text Available Abstract Background Virtually all low- and middle-income countries are undergoing an epidemiological transition whose progression is more varied than experienced in high-income countries. Observed changes in mortality and disease patterns reveal that the transition in most low- and middle-income countries is characterized by reversals, partial changes and the simultaneous occurrence of different types of diseases of varying magnitude. Localized characterization of this shifting burden, frequently lacking, is essential to guide decentralised health and social systems on the effective targeting of limited resources. Based on a rigorous compilation of mortality data over two decades, this paper provides a comprehensive assessment of the epidemiological transition in a rural South African population. Methods We estimate overall and cause-specific hazards of death as functions of sex, age and time period from mortality data from the Agincourt Health and socio-Demographic Surveillance System and conduct statistical tests of changes and differentials to assess the progression of the epidemiological transition over the period 1993–2013. Results From the early 1990s until 2007 the population experienced a reversal in its epidemiological transition, driven mostly by increased HIV/AIDS and TB related mortality. In recent years, the transition is following a positive trajectory as a result of declining HIV/AIDS and TB related mortality. However, in most age groups the cause of death distribution is yet to reach the levels it occupied in the early 1990s. The transition is also characterized by persistent gender differences with more rapid positive progression in females than males. Conclusions This typical rural South African population is experiencing a protracted epidemiological transition. The intersection and interaction of HIV/AIDS and antiretroviral treatment, non-communicable disease risk factors and complex social and behavioral changes will impact

Full Text Available The abundance and distribution of parasitic helminths in populations of African buffaloes, Syncerus caffer, have not been well documented. A total of 28 buffaloes of different ages and sexeswere sampled in the Kruger National Park, South Africa, for nematodes of the small intestine. Three nematode species were identified, namely Cooperia fuelleborni, Cooperia hungi and Trichostrongylus deflexus, with C. hungi being a new country record for African buffalo in South Africa. The overall prevalence was 71%and the average number of worms was 2346 (range: 0–15 980. This is a small burden for such a large mammal. Sex, age and body condition of the buffaloes had no significant effect on worm occurrence.

The South African nuclear programme in a strategic perspective

International Nuclear Information System (INIS)

Zelinka, Martin; Sůsa, Tomáš

2017-01-01

The main idea behind the article is that the strategic aspects of the South African nuclear proliferation programme might be seen from a different point of view. The goal is to gain a perspective by looking into South African history, politics and international status, using these factors as the context for the nuclear programme. First, the authors define the necessary theoretical background, emphasizing the various motivations behind nuclear proliferation. The main focus of the article is on South Africa's motivation – where it came from and which factors influenced it. Among the examined aspects are: historical development and emergence of the regime, internal and external opposition (enemies), international status and the nature of the local political system.

Promoting change through political consciousness: a South African speech-language pathology response to the World Report on Disability.

Science.gov (United States)

Kathard, Harsha; Pillay, Mershen

2013-02-01

In the context of the World Report on Disability, Wylie, McAllister, Davidson, and Marshall (2013) question how speech-language pathologists (SLPs) change practices to benefit under-served people with communication disability. This commentary provides a South African response premised on Political Consciousness. In South Africa, a grossly unequal society, the under-served population is not only those with communication disability but also include those who are at a communication disadvantage due to disabling conditions. As a consequence of the combined effects of a severe shortage of SLPs as well as maldistribution in service provision, the under-served are mainly poor Black South Africans who are the majority population. Political Consciousness allows one to examine how selected forces at the macro-level, meso-level, and micro-level may enable or limit services to the under-served majority. At a macro-level, this study appraises policies and actions advancing and impeding service delivery. At the meso-level it is argued that hegemonic professional knowledge is limiting and an equity-driven population-based approach is advocated. At a micro-level, the Relationship of Labouring Affinities is offered as a conceptual tool for critical engagement. In conclusion, it is suggested that the speech-language pathology profession must collectively become political actors at all levels to effect change.

Emotional trauma affects a large proportion of the South African population. This article addresses its influence on music learners, including its effects on brain development, relational development, learning and music-making. The power of the educator to reshape a child’s brain by providing a nurturing and consistent environment is stressed. The effect of the environment in modulating epigenetic expression is discussed in conjunction with object relations theory as a model for human relatio...

South African uranium resource and production capability estimates

International Nuclear Information System (INIS)

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

1980-09-01

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

Evaluation of microsatellite markers for populations studies and forensic identification of African lions (Panthera leo).

Science.gov (United States)

Miller, Susan M; Harper, Cindy K; Bloomer, Paulette; Hofmeyr, Jennifer; Funston, Paul J

2014-01-01

The South African lion (Panthera leo) population is highly fragmented. One-third of its wild lions occur in small (lions were reintroduced from other areas of the species' historical range. Management practices on these reserves have not prioritized genetic provenance or heterozygosity. These trends potentially constrain the conservation value of these lions. To ensure the best management and long-term survival of these subpopulations as a viable collective population, the provenance and current genetic diversity must be described. Concurrently, poaching of lions to supply a growing market for lion bones in Asia may become a serious conservation challenge in the future. Having a standardized, validated method for matching confiscated lion parts with carcasses will be a key tool in investigating these crimes. We evaluated 28 microsatellites in the African lion using samples from 18 small reserves and 1 captive facility in South Africa, two conservancies in Zimbabwe, and Kruger National and Kgalagadi Transfrontier Parks to determine the loci most suited for population management and forensic genetic applications. Twelve microsatellite loci with a match probability of 1.1×10(-5) between siblings were identified for forensics. A further 10 could be added for population genetics studies. © The American Genetic Association 2014. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

Current management for word finding difficulties by speech-language therapists in South African remedial schools.

Science.gov (United States)

de Rauville, Ingrid; Chetty, Sandhya; Pahl, Jenny

2006-01-01

Word finding difficulties frequently found in learners with language learning difficulties (Casby, 1992) are an integral part of Speech-Language Therapists' management role when working with learning disabled children. This study investigated current management for word finding difficulties by 70 Speech-Language Therapists in South African remedial schools. A descriptive survey design using a quantitative and qualitative approach was used. A questionnaire and follow-up focus group discussion were used to collect data. Results highlighted the use of the Renfrew Word Finding Scale (Renfrew, 1972, 1995) as the most frequently used formal assessment tool. Language sample analysis and discourse analysis were the most frequently used informal assessment procedures. Formal intervention programmes were generally not used. Phonetic, phonemic or phonological cueing were the most frequently used therapeutic strategies. The authors note strengths and raise concerns about current management for word finding difficulties in South African remedial schools, particularly in terms of bilingualism. Opportunities are highlighted regarding the development of assessment and intervention measures relevant to the diverse learning disabled population in South Africa.

The invisibility of men in South African violence prevention policy: national prioritization, male vulnerability, and framing prevention

Science.gov (United States)

van Niekerk, Ashley; Tonsing, Susanne; Seedat, Mohamed; Jacobs, Roxanne; Ratele, Kopano; McClure, Roderick

2015-01-01

Background South Africa has a significant violence problem. The exposure of girls and women to interpersonal violence is widespread, and the victimization of men, especially to severe and homicidal forms of aggression, is of considerable concern, with male homicide eight times the global rate. In the last two decades, there have been a plethora of South African policies to promote safety. However, indications suggest that the policy response to violence is not coherently formulated, comprehensive, or evenly implemented. Objective This study examines selected South African national legislative instruments in terms of their framing and definition of violence and its typology, vulnerable populations, and prevention. Design This study comprises a directed content analysis of selected legislative documents from South African ministries mandated to prevent violence and its consequences or tasked with the prevention of key contributors to violence. Documents were selected using an electronic keyword search method and analyzed independently by two researchers. Results The legislative documents recognized the high levels of violence, confirmed the prioritization of selected vulnerable groups, especially women, children, disabled persons, and rural populations, and above all drew on criminological perspectives to emphasize tertiary prevention interventions. There is a policy focus on the protection and support of victims and the prosecution of perpetrators, but near absent recognition of men as victims. Conclusions There is a need to broaden the policy framework from primarily criminological and prosecutorial perspectives to include public health contributions. It is likewise important to enlarge the conceptions of vulnerability to include men alongside other vulnerable groups. These measures are important for shaping and resourcing prevention decisions and strengthening primary prevention approaches to violence. PMID:26228996

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

Directory of Open Access Journals (Sweden)

Diane Banks

2011-03-01

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

The cost of a healthy diet: a South African perspective.

Science.gov (United States)

Temple, Norman J; Steyn, Nelia P

2011-05-01

Energy-dense foods are relatively cheap sources of energy but typically have a low nutrient density. People with a low income may therefore select a relatively less healthy diet. The high energy density of such diets helps explain the association between obesity and low socioeconomic status. Most studies have been carried out in highly developed countries. We have extended this research to South Africa. Some foods, such as oats, beans, carrots, and apples, are moderately priced sources of energy and are healthy (i.e., they have a low energy density and are nutrient dense). However, such foods are likely to be less desired than many other foods, such as candy, cookies, jam, and chocolate, that have a similar cost (in terms of food energy) but are less healthy. We compared the cost of a typical South African diet with a healthier one. On average, the healthier diet costs 69% more, but this estimate is greatly affected by food choices. For a family whose household income is exceeded by one-third of the population, this increased expenditure represents about 30% of total household income. This could be decreased to about 10% to 15% if a healthy diet is carefully designed. Overall, a healthy diet is unaffordable for most South Africans. This shows the importance of not only educating people in developing countries to the importance of a healthy diet but also explaining how to make such a diet affordable. A more effective strategy is government intervention that manipulates food prices. Copyright © 2011 Elsevier Inc. All rights reserved.

THE INCORPORATION OF DOUBLE TAXATION AGREEMENTS INTO SOUTH AFRICAN DOMESTIC LAW

Directory of Open Access Journals (Sweden)

Izelle du Plessis

2015-11-01

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

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

Directory of Open Access Journals (Sweden)

Hermoine J. Venter

2016-05-01

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