The article focuses on the Indigenous groups in South Africa, collectively referred to as Khoe-San, which includes the San and the Khoikhoi. It provides information about the estimated percentage of the Indigenous population in South Africa, It mentions that South Africa voted in favor of adopting the UN Declaration on the Rights of Indigenous Peoples.

Most research on the non-economic quality of life have been (a) on a national level or performed on cross-country comparisons, and/or (b) used subjective indicators to measure how people perceive their non-economic quality of life. In this paper, our main contribution is to construct objective indicators of the non-economic quality of life for 354 sub-national magisterial districts in South Africa. We also compare changes in these indicators over time, and consider methodological issues in the construction of objective indicators of non-economic quality of life. We find that although income does matter for the overall quality of life, non-income components of the quality of life can make an important difference. We find a number of places with low incomes that have been able to achieve higher than expected outcomes in terms of the non-economic quality of life, and that some of the relative income poor areas have improved their non-economic ranking between 1996 and 2004. We also find that the geographical/environmental quality of life in South Africa is better in non-urban areas, where fewer of the country’s population is residing. Significant improvements in the overall quality of life may be achieved through improvements in the urban natural environment. [ABSTRACT FROM AUTHOR]

Since its inception in 1974, the South African family planning programme has been widely believed to be linked with white fears of growing black numbers. The programme has been repeatedly attacked by detractors as a programme of social and political control. Yet, in spite of the hostile environment, black women's use of services has steadily increased. Using historical and anthropological evidence, this paper delineates the links between the social and political context of racial domination and individual fertility behaviour. It is argued that the quantitative success of the family planning programme is rooted in social and economic shifts conditioning reproductive authority and fertility decision-making. State policies of racial segregation and influx control, ethnic 'homeland' politics, and labour migration of men transformed opportunities and constraints for black women and men, and altered local and household expectations of childbearing. Women came to manage their own fertility as they increasingly found themselves in precarious social and economic circumstances. [ABSTRACT FROM AUTHOR]

This paper presents an insight into water service access and demand, with a numerical review of official data from the national household survey from 1995 to 2006, and the 1996 and 2001 census data. The findings show that in provinces (Eastern Cape, Limpopo and Mpumalanga) where the existing service base is low, with a relatively high level of outmigration leading to a decrease in household numbers, the annual rate of delivery is lower than in other areas and percentage access has risen marginally (from about 68% to 70%). In provinces (North West, Northern Cape and KwaZulu-Natal) where the existing service base is higher, with relatively lower levels of out-migration, there is a marginal change in household numbers and the annual rate of delivery is higher and percentage access has risen remarkably (from about 72% to 88%). In the provinces (Gauteng, Western Cape and Free State) with the most favourable initial conditions, that is, where the existing service base is the highest, there is a remarkable change in household numbers, possibly as a result of in-migration and the annual rate of delivery is quite sustainable. Percentage access rises at an early stage and remains stable at the limiting value of about 98%. [ABSTRACT FROM AUTHOR]

This paper describes marriage and partnership patterns and trends in rural KwaZulu-Natal, South Africa from 2000-2006. The study is based on longitudinal, population-based data collected by the Africa Centre demographic surveillance system. We consider whether the high rates of non-marriage among Africans in South Africa reported in the 1980s were reversed following the political transformation underway by the 1990s. Our findings show that marriage has continued to decline with a small increase in cohabitation among unmarried couples, particularly in more urbanised areas. Comparing surveillance and census data, we highlight problems with the use of the 'living together' marital status category in a highly mobile population. [ABSTRACT FROM AUTHOR]

This paper presents an historical analysis (1974–97) of associations between land-cover change and socio-economic factors for three villages in a former bantustan region of South Africa. The notion of social–ecological systems is used as the conceptual framework for this analysis, in which the former bantustan region of Bushbuckridge is posited as a cultural landscape. The local landscape showed distinctive modifications over the study period, broad trends including the growth of human settlements and the decrease in woodland cover. However, changes were not uniform across sites, and the direction and magnitude of changes in land cover were often nonlinear and site-specific. Analysis of associations between biophysical and socio-economic changes at different scales revealed a range of important interacting forces such as population growth, drought, shortages of land, grazing and wood resources, weakening institutional governance of natural resources, and the diversification of livelihood strategies, including the sale of fuelwood, concurrent with declining employment security and cattle ownership. Evidence suggests a possible erosion of resilience in these social–ecological systems at various scales, with important implications for socio-economic development and sustainable resource management.

Inadequate data and apartheid policies have meant that, until recently, most demographers have not had the opportunity to investigate the level of, and trend in, the fertility of South African women. The 1996 South Africa Census and the 1998 Demographic and Health Survey provide the first widely available and nationally representative demographic data on South Africa since 1970. Using these data, this paper describes the South African fertility decline from 1955 to 1996. Having identified and adjusted for several errors in the 1996 Census data, the paper argues that total fertility at that time was 3.2 children per woman nationally, and 3.5 children per woman for African South Africans. These levels are lower than in any other sub-Saharan African country. We show also that fertility in South Africa has been falling since the 1960s. Thus, fertility transition predates the establishment of a family planning programme in the country in 1974. [ABSTRACT FROM AUTHOR]

This paper presents an attempt to elucidate the character and mechanics of population growth among a group that can be loosely equated with the Whites or Afrikaners in the Cape Colony in the eighteenth century. Essentially it is an overview, because many of the details, which are needed for a full demographic analysis, are lacking. Nevertheless, it is hoped that it may be interesting to demographers, for the purposes of comparison, especially since many of the features of the South African population have close parallels in other settler situations, such as French Canada and New England. It is also hoped that this paper will form the beginning of the establishment of the social history of early South Africa on a basis, which the concerns of previous historians have not given it. After an evaluation of the reliability of these sources, it proceeds to give estimates of the gross population growth rate, of the importance of immigration, of the sex ratio and of such aspects of nuptiality and fertility as can be ascertained in the absence of systematic information on the dates of death of individuals. Finally, it attempts to show the effect of the demographic structure on the social development of the colony.

This paper reports on an interview study of contraceptive practice among a representative sample of 1,022 white married women in Johannesburg, South Africa. It was found that most of the couples have used contraception at some time during their married life, the highest use being among fecund couples. A high proportion of couples used contraceptives before their first pregnancy, and a very small proportion of fecund women never use any form of contraception at all during their married lives.

A survey of the quality of water flowing from micro-system types to the ocean, along the subtropical east coast of South Africa, showed a wide variation in the concentrations of total nitrogen, phosphorus and phytoplankton biomass in the different systems located, in many cases, only a short distance from each other along the coastline. The origins of the high phytoplankton growth indicate pollutants caused by the land-use in this highly populated coastal region. The main agricultural activities in the area are sugarcane, permanent orchards, and forestry. The levels of N and P in the water varied from ‘good’ to ‘poor’, i.e., TN 0.15–3.99 mg·L−1, TP 0.02–0.33 mg·L−1 and chlorophyll-a from 0 to almost 45 µg·L−1. Rapid coastal population densification appears to have been the cause of the pollution levels measured for total nitrogen, phosphorus, and phytoplankton biomass. Most of the micro-systems with a total modified peri-catchment above 80% were enriched by both TN and TP. While the hypothesis tested was that the main cause was residential development (e.g., septic tank effluent), it was not possible to show any statistical significance to support such a specific conclusion. Although these systems are small individually, the great number along the coastline warrants recognition as important sources of freshwater inflow and nutrients to the marine environment.

Purpose - This research aims to characterise the landscape and factors for successfully implementing Systems Engineering (SE) and Model-Based Systems Engineering (MBSE) in the enterprise. Research methodology - The study investigated the factors across different industries that affect the success of MBSE in an enterprise using a survey questionnaire. The research focussed on the uptake and implementation of MBSE in Small and Medium-sized enterprises (SMEs) in South Africa. More than 100 industry professionals participated in the study. Findings - The survey revealed that SMEs have trouble adopting and implementing MBSE because they are unaware of its applicability and lack economic justification and support from upper management. Quantitative data analysis assessed how factors such as MBSE training, existing SE processes in the enterprise, and how long the company has been using MBSE contribute to the success of MBSE adoption in SMEs. Research limitations - The population size limited the study reached and the time available to conduct the research. However, it does not reduce the results' strength and validity. Practical implications - The analysis showed that training and an existing SE structure are highly significant, while the age of MBSE in the enterprise does not correlate with its success. Therefore, these results proposed an adoption framework for SMEs in South Africa to aid MBSE adoption by incorporating training and a clear uptake and implementation process. Originality/Value - This research builds on the growing body of literature about implementing MBSE and enterprises. The conclusions provide valuable insights and guidelines for implementing MBSE in SMEs. [ABSTRACT FROM AUTHOR]

Recent work on assessing household food insecurity has focused mainly on experiential-based measures using qualitative survey questions. In this paper, we employed two quantitative measures to estimate prevalence rates for household food insecurity in South Africa. One measure, termed food poverty, assessed whether the amount spent by a household on food was inadequate to purchase a low cost food plan. Low energy availability assessed whether the food energy available to a household, through its purchases and home production, was less than the sum of its members' recommended energy intakes. The 1995 Income and Expenditure Survey, a large representative survey of South African households (n = 28,704), was used for this secondary data analysis. Results showed that 43% of households were in food poverty in October 1995, and 55% had a low energy availability. These indicators allowed classification of households into four groups: food poverty only; low energy availability only; food insecure on both measures; and food secure. These groups differed on various aspects of household food consumption, suggesting that these indicators can be used to target different types of interventions to meet specific needs. Both bivariate and multivariate analyses showed that households that were food insecure on both measures were more likely to be in rural areas, have low incomes or large household sizes, and be headed by Africans or individuals of mixed ancestry. These patterns of food insecurity were corroborated by previous research on income poverty and nutritional status, suggesting that food poverty and low energy availability are useful, quantitative indicators for assessing food insecurity in South Africa.

Background: Global and local ancestry inference in admixed human populations can be performed using computational tools implementing distinct algorithms. The development and resulting accuracy of these tools has been tested largely on populations with relatively straightforward admixture histories but little is known about how well they perform in more complex admixture scenarios. Results: Using simulations, we show that RFMix outperforms ADMIXTURE in determining global ancestry proportions even in a complex 5-way admixed population, in addition to assigning local ancestry with an accuracy of 89%. The ability of RFMix to determine global and local ancestry to a high degree of accuracy, particularly in admixed populations provides the opportunity for more accurate association analyses. Conclusion: This study highlights the utility of the extension of computational tools to become more compatible to genetically structured populations, as well as the need to expand the sampling of diverse world-wide populations. This is particularly noteworthy as modern-day societies are becoming increasingly genetically complex and some genetic tools and commonly used ancestral populations are less appropriate. Based on these caveats and the results presented here, we suggest that RFMix be used for both global and local ancestry estimation in world-wide complex admixture scenarios particularly when including these estimates in association studies.

This paper offers a look at projections for the world population in 2000-2050. World population reached 6.1 billion in mid-2000 and is currently growing at an annual rate of 1.2 percent or 77 million people per year. The population of more developed regions, currently 1.2 billion is anticipated to change little during the next 50 years because fertility levels are expected to remain below replacement level. By 2050 the less developed regions are expected to attain a life expectancy of 75 years whereas in the more developed regions the projected level is 82 years, implying that the gap between the two groups may narrow. Only in South Africa, whose fertility is lower than that of Botswana or Zimbabwe, does the growth rate of the population become negative during 2010-2025, being positive thereafter. Although the probability of being infected by HIV is assumed to decline significantly in the future, the long-term impact of the epidemic remains dire. The population aged 60 or over in the more developed regions constitutes today about 20 percent of the population and by 2050, it will likely account for 33 percent of the population. International migration is projected to remain high during the 21st century.

Background: There is a lack of reliable data in developing countries to inform policy and optimise resource allocation. Health and socio-demographic surveillance sites (HDSS) have the potential to address this gap. Mortality levels and trends have previously been documented in rural South Africa. However, complex space--time clustering of mortality, determinants, and their impact has not been fully examined. Objectives: To integrate advanced methods enhance the understanding of the dynamics of mortality in space--time, to identify mortality risk factors and population attributable impact, to relate disparities in risk factor distributions to spatial mortality risk, and thus, to improve policy planning and resource allocation. Methods: Agincourt HDSS supplied data for the period 1992--2008. Advanced spatial techniques were used to identify significant age-specific mortality 'hotspots' in space--time. Multivariable Bayesian models were used to assess the effects of the most significant covariates on mortality. Disparities in risk factor profiles in identified hotspots were assessed. Results: Increasing HIV-related mortality and a subsequent decrease possibly attributable to antiretroviral therapy introduction are evident in this rural population. Distinct space--time clustering and variation (even in a small geographic area) of mortality were observed. Several known and novel risk factors were identified, and population impact was quantified. Significant differences in the risk factor profiles of the identified 'hotspots' included ethnicity; maternal, partner, and household deaths; household head demographics; migrancy; education; and poverty. Conclusions: A complex interaction of highly attributable multilevel factors continues to demonstrate differential space--time influences on mortality risk (especially for HIV). High-risk households and villages displayed differential risk factor profiles. This integrated approach could prove valuable to decision makers. Tailored interventions for specific child and adult high-risk mortality areas are needed, such as preventing vertical transmission, ensuring maternal survival, and improving water and sanitation infrastructure. This framework can be applied in other settings within the region. [ABSTRACT FROM AUTHOR]

Demography, migration and natural selection are predominant processes affecting the distribution of genetic variation among natural populations. Many studies use neutral genetic markers to make inferences about population history. However, the investigation of functional coding loci, which directly reflect fitness, is critical to our understanding of species' ecology and evolution. Immune genes, such as those of the Major Histocompatibility Complex (MHC), play an important role in pathogen recognition and provide a potent model system for studying selection. We contrasted diversity patterns of neutral data with MHC loci, ELA-DRA and -DQA, in two southern African plains zebra (Equus quagga) populations: Etosha National Park, Namibia, and Kruger National Park, South Africa. Results from neutrality tests, along with observations of elevated diversity and low differentiation across populations, supported previous genus-level evidence for balancing selection at these loci. Despite being low, MHC divergence across populations was significant and may be attributed to drift effects typical of geographically separated populations experiencing little to no gene flow, or alternatively to shifting allele frequency distributions driven by spatially variable and fluctuating pathogen communities. At the DRA, zebra exhibited geographic differentiation concordant with microsatellites and reduced levels of diversity in Etosha due to highly skewed allele frequencies that could not be explained by demography, suggestive of spatially heterogeneous selection and local adaptation. This study highlights the complexity in which selection affects immune gene diversity and warrants the need for further research on the ecological mechanisms shaping patterns of adaptive variation among natural populations.

In this interview, human biologist Noel Cameron reflects on his work on child growth and development in post-apartheid South Africa. The conversation focuses in particular on Cameron's involvement with a cohort study called Birth to Twenty, which sought to determine the health impacts of apartheid on black children born in the year Nelson Mandela became president. Cameron considers the extent to which human population biology can contribute to the creation of new and potentially improved health realities for marginalized communities in the Global South.

Information on the magnitude of orphanhood is important from various perspectives. Though not designed for that purpose, orphanhood questions have been used by some studies to infer the magnitude of orphans due to AIDS among younger persons. This study provides an historical overview of the orphanhood questions and estimates the magnitude of orphans in the era of HIV/AIDS in South Africa using an epidemiologic and demographic model. The results suggest that the number of orphans in South Africa may increase to about 1.9 million by 2015 if current trends continue. These figures are lower than estimated by some previous studies.

Background: HbA1c has been the gold standard for glycaemic control follow-up for decades. In 2009, a level of 6.5% (48 mmol/mol) was proposed as diagnostic for diabetes. We test this cut-off in our community. Methods: Participants (946) from a community-based study were screened for diabetes using either a fasting blood glucose or oral glucose tolerance test (OFTT). The HbA1c cut-off of 6.5% was tested for each group. A receiver operator characteristic (ROC) curve for both groups was generated to establish an optimal cut-off. Results: Our study included 224 (23.7%) males and 722 (76.3%) females. Using fasting blood glucose alone, 117 (14%) were diagnosed with diabetes 250% had an HbA1c value of $6.5% (48 mmol/mol). Using an OGTT, 147 (18%) were diagnosed with diabetes 246% had an HbA1c value of $6.5% (48 mmol/mol). ROC curves found a level of 6.1% (43 mmol/mol) to be optimal in both groups (AUC 0.85 and 0.82 respectively). The sensitivities were 80% and 75% and the specificities 77% and 78% respectively. Conclusions: A cut off of 6.5% (48 mmol/mol) is a good diagnostic tool with its high specificity; however the low sensitivity limits its use. We found a level of 6.1% (43 mmol/mol) to be optimal. This emphasizes the need for evidenced based values to be established in various population groups. [ABSTRACT FROM AUTHOR]

The article discusses the self-determination rights of cultural, religious and linguistic communities in South Africa. It mentions that the country constitutes the most diverse plural composition in the whole world and known for the polarization factions of its population. It cites the country's abandonment of territorial segregation as a way for peaceful co-existence of racial and ethnic groups and its efforts to avoid homogeneity. It also points out that its constitutional preamble expresses the belief that people who live in the African nation are united through diversity.

This study investigates the genetic diversity, population structure and demographic history of the afrotropical butterfly Bicyclus anynana using mitochondrial DNA (mtDNA). Samples from six wild populations covering most of the species range from Uganda to South Africa were compared for the cytochrome c oxidase subunit gene (COI). Molecular diversity indices show overall high mtDNA diversity for the populations, but low nucleotide divergence between haplotypes. Our results indicate relatively little geographic population structure among the southern populations, especially given the extensive distributional range and an expectation of limited gene flow between populations. We implemented neutrality tests to assess signatures of recent historical demographic events. Tajima's D test and Fu's FS test both suggested recent population growth for the populations. The results were only significant for the southernmost populations when applying Tajima's D, but Fu's FS indicated significant deviations from neutrality for all populations except the one closest to the equator. Based on our own findings and those from pollen and vegetation studies, we hypothesize that the species range of B. anynana was reduced to equatorial refugia during the last glacial period, and that the species expanded southwards during the past 10.000 years. These results provide crucial background information for studies of phenotypic and molecular adaptation in wild populations of B. anynana. [ABSTRACT FROM AUTHOR]

Background: Time-to-pregnancy (TTP) has never been studied in an African setting and there are no data on the rates of adverse pregnancy outcomes in South Africa. The study objectives were to measure TTP and the rates of adverse pregnancy outcomes in South Africa, and to determine the reliability of the questionnaire tool. Methods: The study was cross-sectional and applied systematic stratified sampling to obtain a representative sample of reproductive age women for a South African population. Data on socio-demographic, work, health and reproductive variables were collected on 1121 women using a standardized questionnaire. A small number (n = 73) of randomly selected questionnaires was repeated to determine reliability of the questionnaire. Data was described using simple summary statistics while Kappa and intra-class correlation statistics were calculated for reliability. Results: Of the 1121 women, 47 (4.2%) had never been pregnant. Mean gravidity was 2.3 while mean parity was 2.0 There were a total of 2467 pregnancies; most (87%) resulted in live births, 9.5% in spontaneous abortion and 2.2% in still births. The proportion of planned pregnancies was 39% and the median TTP was 6 months. The reliability of the questionnaire for TTP data was good; 63% for all participants and 97% when censored at 14 months. Overall reliability of reporting adverse pregnancy outcomes was very high, ranging from 90 - 98% for most outcomes. Conclusion: This is the first comprehensive population-based reproductive health study in South Africa, to describe the biologic fertility of the population, and provides rates for planned pregnancies and adverse pregnancy outcomes. The reliability of the study questionnaire was substantial, with most outcomes within 70 - 100% reliability index. The study provides important public information for health practitioners and researchers in reproductive health. It also highlights the need for public health intervention programmes and epidemiological research on biologic fertility and adverse pregnancy outcomes in the population. [ABSTRACT FROM AUTHOR]

Background: It is widely accepted that assessing the impact of heat on populations is an important aspect of climate change research. However, this raises questions about how best to measure people's exposure to heat under everyday living conditions in more detail than is possible by relying on nearby sources of meteorological data. Objective: This study aimed to investigate practical and viable approaches to measuring air temperature and humidity within a population, making comparisons with contemporaneous external data sources. This was done in a rural South African population during the subtropical summer season. Results: Air temperature and humidity were measured indoors and outdoors at three locations over 10 days and the datalogger technology proved reliable and easy to use. There was little variation in measurements over distances of 10 km. Conclusions: Small battery-powered automatic dataloggers proved to be a feasible option for collecting weather data among a rural South African population. These data were consistent with external sources but offered more local detail. Detailed local contemporary data may also allow post hoc modelling of previously unmeasured local weather data in conjunction with global gridded climate models. [ABSTRACT FROM AUTHOR]

Background: Current information about the expansion of Bantu-speaking peoples is hampered by the scarcity of genetic data from well identified populations from southern Africa. Here, we fill an important gap in the analysis of the western edge of the Bantu migrations by studying for the first time the patterns of Y-chromosome, mtDNA and lactase persistence genetic variation in four representative groups living around the Namib Desert in southwestern Angola (Ovimbundu, Ganguela, Nyaneka-Nkumbi and Kuvale). We assessed the differentiation between these populations and their levels of admixture with Khoe-San groups, and examined their relationship with other sub-Saharan populations. We further combined our dataset with previously published data on Y-chromosome and mtDNA variation to explore a general isolation with migration model and infer the demographic parameters underlying current genetic diversity in Bantu populations. Results: Correspondence analysis, lineage sharing patterns and admixture estimates indicate that the gene pool from southwestern Angola is predominantly derived from West-Central Africa. The pastoralist Herero-speaking Kuvale people were additionally characterized by relatively high frequencies of Y-chromosome (12%) and mtDNA (22%) Khoe-San lineages, as well as by the presence of the -14010C lactase persistence mutation (6%), which likely originated in non-Bantu pastoralists from East Africa. Inferred demographic parameters show that both male and female populations underwent significant size growth after the split between the western and eastern branches of Bantu expansions occurring 4000 years ago. However, males had lower population sizes and migration rates than females throughout the Bantu dispersals. Conclusion: Genetic variation in southwestern Angola essentially results from the encounter of an offshoot of West-Central Africa with autochthonous Khoisan-speaking peoples from the south. Interactions between the Bantus and the Khoe-San likely involved cattle herders from the two groups sharing common aspects of their social organization. The presence of the -14010C mutation in southwestern Angola provides a link between the East and Southwest African pastoral scenes that might have been established indirectly, through migrations of Khoe herders across southern Africa. Differences in patterns of mtDNA and Y-chromosome intrapopulation diversity and interpopulation differentiation may be explained by contrasting demographic histories underlying the current female and male genetic variation.

(1) An epidemiological study of an urban South African Negro community has been carried out in Johannesburg. Altogether 964 respondents were examined and in each case radiographs of the hands and feet were obtained. Rheumatoid factor tests were carried out on 404 serum samples. (2) Rheumatoid arthritis (RA) was graded 'definite' or 'probable' on the basis of a modification of the Rome criteria (Kellgren, Jeffrey, and Ball, 1963a). (3) In marked contrast to the findings in rural Africans the prevalence of RA in this community was similar to that in Caucasian populations. Five respondents (all elderly women) had 'definite' RA, giving a prevalence of 1.4% of the females and 0.9% of the total population sample over 15 years old. The prevalence of 'definite' and 'probable' RA combined was 2.6% for males, 3.7% for females, and 3.3% for all individuals over 15 years old. Prevalence increased with age, reaching a maximum in the 65- to 74-year cohort. (4) The form and severity of the clinical and radiological features were unlike the mild manifestations seen in rural African peoples and closely resembled the usual clinical picture of rheumatoid disease. (5) The latex fixation test was positive in 12.1% of the sera tested, which is similar to the high titres found in other African populations. No obvious cause for this phenomenon was found. (6) Several reasons for the marked difference in prevalence of RA between this urban African population and a rural African population are considered. Marked intraracial differences such as this point to the importance of sociological and environmental factors in the pathogenesis of rheumatoid arthritis. [ABSTRACT FROM PUBLISHER]

The article explores on the implementation of political reform in South Africa. Since 1948, it has been ruled by the Afrikaner National Party, an all-white parliament, but in 1997, the government announced that it was considering a new constitution that would include other races. Thus, it allowed eighty-five Coloureds in the House of Representatives and forty-five Indians in the House of Delegates where each group has limited powers while the House of Assembly has 178 white members. However, its black people who make up the 73.8% of its total population have not been included in the constitutional plans. It inferred that the scenario has prompted the arose of opposition forces because it promised no fundamental change to the country's racist legislation.

The key to explaining and predicting changes in South African society lies in the fact that a cutting point can be defined on the dimension of power-authority-ability to make or influence decisions affecting the life chances of the whole population-that comes very near dividing "whites" from "nonwhites." If (1) the dominant issue is the distribution of power- authority and (2) "the South African problem" is viewed as a two-party conflict with racially defined parties, then there are eight possible resolutions of the conflict, classifiable as annihilative, integrationist and separatist. The available evidence indicates that from least to most likely are annihilative, integrationist and separatist resolutions. Within the separatist category, secessionist resolutions appear less likely than a segregationist resolution-specifically a form of segregation clearly leading to a federal structure. Analysis of the South African case suggests for comparative research generalizations about intrasocietal racial conflicts. [ABSTRACT FROM AUTHOR]
