The 'home' in homeland: gender,national space,and Inkatha's politics of ethnicity

In South Africa, a country in which the manipulation of ethnicity was at the heart of the government's attempts to establish control over the majority African population, ethnic mobilization during the liberation struggle was singularly unsuccessful. The one exception was Chief Mangosuthu Buthelezi's controversial Inkatha movement. This article suggests that one of the reasons for Inkatha's successes was the astute way in which the organization and, in particular, Buthelezi played on gendered notions of 'home' and 'homeland'. Historically, apartheid constructed notions of home and space differently for women and men and Inkatha was able to draw upon and manipulate these differences to produce a powerfully felt response. Thus, for men, many of them migrant workers in South Africa's cities, the notion of 'home' implied a return to patriarchal values and male domestic control in a historically constituted 'homeland'; for women, Buthelezi emphasized the new 'modern' opportunities opened up by the KwaZulu homeland, and the importance of their 'God-given' gifts of motherhood.     

Physical growth in a transitional economy: the aftermath of South African apartheid

The economic transition in developing countries is not always the result of the change from a centrally-planned to a free-market economy, but may be found within an already existing free-market economy as a result of profound political change, as in South Africa. The release of Nelson Mandela in February 1990 heralded an end both to the political system of apartheid and to the concomitant social, political, and economic disenfranchisement of 30 million non-White people in South Africa. The first freely elected non-White government came to power in 1994 and initiated a number of social and economic reforms aimed at alleviating the worst consequences of apartheid. This paper examines the effect of post-apartheid economic and social transition on the growth and development of urban children. Over 4000 children born in Soweto and Johannesburg were enrolled in the Birth to Ten (BTT) birth-cohort study in 1990. Whilst these children were born with lower birth weights than in developed countries, they did grow strongly in infancy, particularly in weight, to reflect normal reference values for body mass index (BMI) by 1 year of age. While post-apartheid social and economic changes were expected to take some time to affect child growth and development, the rate of change has been slower than expected. Data from the BTT study demonstrate that the growth of White children continues to be superior to that of their non-White peers and differences that existed at birth and during infancy have not diminished during childhood and early adolescence. Whatever factors are changed at the national or community levels during economic (and social) transition in South Africa appear not yet to have resulted in improved child physical growth.     

Black Jews in the Northern Province: a study of ethnic identity in South Africa

The article examines ways in which the Lemba people of the Northern Province of South Africa have used their oral history and traditional customs associated with distant Semitic origins in Yemen, to claim a modern Jewish identity in racially divided South Africa. While Lemba live in Mozambique and Zimbabwe as well as in South Africa, it is only in the latter that belief in a Jewish origin is found. The article seeks to show that early white missionaries and colonial officials propagated a Semitic identity for the Lemba and in their writings emphasized the differences between the Lemba and their African neighbours through comparisons of Lemba customs with Jewish communities in Europe. Such writings contributed to an ethos of a distinct identity, through which, via the establishment of the Lemba Cultural Association, middle-class Lemba intellectuals sought to promote the Lemba. This was achieved in a situation where the apartheid regime in South Africa pursued a divide and rule policy which allowed the Bantustans to discriminate against ethnic minorities under their control.     

Additional fossil Theropithecus from Hopefield, South Africa: a comparison with other African sites and a reevaluation of its taxonomic status

Additional fossil Theropithecus remains, recovered from mid to late Pleistocene deposits near Hopefield , South Africa, include portions of the jaws of at least five individuals. Extensive comparisons with fossil Theropithecus from other African sites, including Makapan , Swartkrans , Kanjera , Olorgesailie , and Olduvai , reveal few morphological differences, especially when variation in modern gelada baboons ( Theropithecus gelada ) and savannah baboons (Papio) is considered. The most pronounced differences between fossil forms are overall size and relative P3 length. However, these traits do not separate the fossil forms either chronologically or geographically. Other traits, such as depth of the fossa of the mandibular corpus, slope of the upper symphyseal shelf, and variation in the depth of the mandibular corpus, do not distinguish alleged primitive forms ( Makapan and lower beds at Olduvai ) from remains found at Hopefield , Swartkrans , Kanjera , Olorgesailie , Olduvai Bed IV, or the lower Ndutu Beds. Other traits, such as canine crown height and incisor size, are poorly documented for fossil Theropithecus . Thus, the available evidence suggests that Theropithecus darti and its successional species, T. oswaldi , can best be considered as a single fossil species, T. oswaldi , of which the remains from Hopefield are a late representative. Furthermore, lack of morphological differences dictates that Hopefield Theropithecus not be considered a distinct subspecies. Variation within the Hopefield sample shows that only one taxa is found at this site. Hypothesized physical and climatic conditions at Hopefield during the Pleistocene suggest that T. oswaldi lived near vleis or fresh water lagoons. Comparisons with modern T. gelada suggest a graminivorous diet for the fossil form.     

Refugia, dispersal and divergence in a forest archipelago: a study of Streptocarpus in eastern South Africa

We describe a scenario of plant speciation across a relict forest archipelago in South Africa involving Pleistocene habitat expansion-contraction cycles, dispersal and adaptation to lower temperatures. This is the first population level study using molecular data in South African forests and has significant implications for conservation efforts in this area. Populations of the mesophytic forest floor herbs Streptocarpus primulifolius sensu lato and Streptocarpus rexii were sampled throughout their range in the naturally fragmented forests of eastern South Africa in order to investigate population genetic and phylogenetic patterns within the species complex, using nuclear microsatellites, nuclear ribosomal ITS (internal transcribed spacer) sequences and chloroplast genome sequences. S. primulifolius harbours high levels of genetic diversity at both the nuclear (mean HE = 0.50) and the chloroplast level (each population fixed for a unique haplotype). This is consistent with populations of these coastal species being Pleistocene relicts. In contrast, populations of S. rexii in cooler habitats at higher altitudes and lower latitudes harbour little or no nuclear genetic diversity (mean HE = 0.09) and most share a common chloroplast haplotype. The split of S. rexii from populations intermediate between the two species (S. cf. primulifolius) occurred between 0 and 0.44 million years ago according to the calibrated ITS phylogeny of the taxa. The low genetic diversity and homogeneity of S. rexii is congruent with this species having reached its current range during the Holocene. We found no evidence of monophyly of any of the taxa in this study, which we consider a consequence of recent evolution in a fragmented habitat.     

Projected climate impacts to South African maize and wheat production in 2055: a comparison of empirical and mechanistic modeling approaches

Crop model‐specific biases are a key uncertainty affecting our understanding of climate change impacts to agriculture. There is increasing research focus on intermodel variation, but comparisons between mechanistic (MMs) and empirical models (EMs) are rare despite both being used widely in this field. We combined MMs and EMs to project future (2055) changes in the potential distribution (suitability) and productivity of maize and spring wheat in South Africa under 18 downscaled climate scenarios (9 models run under 2 emissions scenarios). EMs projected larger yield losses or smaller gains than MMs. The EMs’ median‐projected maize and wheat yield changes were ?3.6% and 6.2%, respectively, compared to 6.5% and 15.2% for the MM. The EM projected a 10% reduction in the potential maize growing area, where the MM projected a 9% gain. Both models showed increases in the potential spring wheat production region (EM = 48%, MM = 20%), but these results were more equivocal because both models (particularly the EM) substantially overestimated the extent of current suitability. The substantial water‐use efficiency gains simulated by the MMs under elevated CO₂ accounted for much of the EM?MM difference, but EMs may have more accurately represented crop temperature sensitivities. Our results align with earlier studies showing that EMs may show larger climate change losses than MMs. Crop forecasting efforts should expand to include EM?MM comparisons to provide a fuller picture of crop–climate response uncertainties.     

"Showing roughness in a beautiful way": talk about love, coercion, and rape in South African youth sexual culture

Sexual violence within as well as outside sexual relationships has far-reaching public health and human rights implications and is a continuing focus of popular debate, media coverage, and research in postapartheid South Africa. Partly because it has been shown to affect individual vulnerability to HIV/AIDS, sexual violence has in recent years become framed as a global public health issue. International research efforts to document the scale of this personally and politically sensitive problem can encounter conceptual, definitional, and methodological difficulties that anthropology is well placed to assist in alleviating. This article offers an ethnographic exploration of the spectrum of practices relating to sexual coercion and rape among young people in a township in the former Transkei region of South Africa. Contextualizing meanings of sexual coercion within local youth sexual culture, the article considers two emic categories associated with sex that is "forced": ukulala ngekani: "to sleep with by force" or ukunyanzela: "to force," both usually used to describe episodes occurring within sexual partnerships; and ukudlwengula, used to describe rape by a nonpartner or stranger. The article discusses the semantic content of and differences between these two key categories, demonstrating that encounters described as "forced sex" encompass not only various forms of sexual coercion but also, particularly in the narratives of young men, instances of more consensual sex. Of importance, in turn, in defining an act as "rape" rather than as "forced sex" are the character of the relationship between the two parties and interlinked ideas relating to exchange and sexual entitlement, love, and the importance of "intention," violation, and "deserving" victimhood.     

Studies of fossil hyaenids: the genera Hyaenictis Gaudry and Chasmaporthetes Hay, with a reconsideration of the Hyaenidae of Langebaanweg, South Africa

The fossil hyaenids from Langebaanweg in South Africa are revised taxonomically using both morphological comparisons and measurement data. Ictilherium preforfex is found to be a synonym of Ikelohyaena abronia . Other hyaenid taxa in this fauna are Hyaenictitherium namaquensis, Chasmaporthetes australis and a new taxon similar to Chasmaporthetes australis in the size and shape of the M₁, trigonid and other characters, but differing from this taxon in having short P₃ relative to P₂, a smaller anterior accessory cusp on P₄ and M₂, present. This taxon has previously been referred to Euryboas sp***, but comparison with Eurasian hyaenids indicates that it shares diagnostic characters with Hyaenictis graeca , type species of the genus Hyaenictis . This genus is poorly known and its content is reviewed. We find that only the new species from Langebaanweg, formally described as Hyaenictis hendeyi sp. nov. , and the Spanish Hyaenictis almerai probably belong in this genus, while other taxa intermittently referred to Hyaenictis belong to other genera. Thus, neither Leecyaena bosei nor Chasmaporthetes silberbergi belong in Hyaenictis .     

Tube-snouted gymnotiform and mormyriform fishes: convergence of a specialized foraging mode in teleosts

Synopsis African mormyriform and South American gynmotiform fishes are unique among freshwater fishes in their abilities to generate and perceive an electrical field that aids in orientation, prey detection, and communication. Here we present evidence from comparative ecology and morphology that tube-snouted electric fishes of the generaSternarchorhynchus (Apteronotidae) andCampylomormyrus (Mormyridae) may be unique among fishes in their mode of foraging by grasp-suction. The grasp-suction mode of feeding is a specialization for extracting immature stages of aquatic insects that burrow into, or hide within, interstitial spaces and holes in matrices of compacted clay particles that form the channel bottom of many tropical lowland rivers. Ecomorphological implications of the remarkable evolutionary convergence for this specialized mode of foraging by tube-snouted electric fishes provide a challenge to Liem's (1984, 1990) theory of separate aquatic and terrestrial vertebrate feeding modes.Invited Editorial     

Warm-up rates during arousal from torpor in heterothermic mammals: physiological correlates and a comparison with heterothermic insects

Summary This study examines the relationship between warm-up rate, body mass, metabolic rate, thermal conductance and normothermic body temperature in heterothermic mammals during arousal from torpor. Predictions based on the assumption that the energetic cost of arousal has been minimised are tested using data for 35 species. The observation that across-species warm-up rate correlates negatively with body mass is confirmed using a comparative technique which removes confounding effects due to the non-independence of species data due to shared common ancestry. Mean warm-up rate during arousal correlates negatively with basal metabolic rate and positively with the temperature difference through which the animal warms, having controlled for other factors. These results suggest that selection has operated to minimise the overall energetic, cost of warm-up. In contrast, peak warm-up rate during arousal correlates positively with peak metabolic rate during arousal, and negatively with thermal conductance, when body mass has been taken into account. These results suggest that peak warm-up rate is more sensitive to the fundamental processes of heat generation and loss. Although heterothermic marsupials have lower normothermic body temperatures and basal metabolic rates, marsupials and heterothermic eutherian mammals do not differ systematically in warm-up rate. Pre-flight warm-up rates in one group of endothermic insects, the bees, are significantly higher than predictions based on rates of arousal of a mammal of the same body mass.Abbreviations BMR basal metabolic rate - ICM independent comparisons method - MWR mean warm-up rate - PMR peak metabolic rate - PWR peak·warm-up rate - Tb_activity body temperature during activity - Tb_torpor body temperature during torpor - T _arousal increase in body temperature during arousal     

Childhood environmental harshness predicts coordinated health and reproductive strategies: A cross-sectional study of a nationally representative sample from France

There is considerable variation in health and reproductive behaviours within and across human populations. Drawing on principles from Life History Theory, psychosocial acceleration theory predicts that individuals developing in harsh environments decrease their level of somatic investment and accelerate their reproductive schedule. Although there is consistent empirical support for this general prediction, most studies have focused on a few isolated life history traits and few have investigated the way in which individuals apply life strategies across reproductive and somatic domains to produce coordinated behavioural responses to their environment. In our study, we thus investigate the impact of childhood environmental harshness on both reproductive strategies and somatic investment by applying structural equation modeling (SEM) to cross-sectional survey data obtained in a representative sample of the French population (n = 1015, age: 19–87 years old, both genders). This data allowed us to demonstrate that (i) inter-individual variation in somatic investment (e.g. effort in looking after health) and reproductive timing (e.g. age at first birth) can be captured by a latent fast-slow continuum, and (ii) faster strategies along this continuum are predicted by higher childhood harshness. Overall, our results support the existence of a fast-slow continuum and highlight the relevance of the life history approach for understanding variations in reproductive and health related behaviours.     

Use of a cytogenetic whole-genome comparison to resolve phylogenetic relationships among three species: implications for mammalian systematics and conservation biology

The objective was to apply a novel modification of a genome-wide, comparative cytogenetic technique (comparative genomic hybridization, comparative genomic hybridization (CGH)), to study species belonging to the myrmecophagous (ant/termite eating) mammalian orders/superorders (Pholidota, Tubulidentata, Carnivora, and Xenarthra), as a model for other applications in mammalian systematics and conservation biology. In this study, CGH was applied to high-quality metaphase spreads of pangolin (Pholidota), using probes of sloth and canine (Xenarthra and Carnivora, respectively) genomic DNA labeled with different fluorophores, thereby facilitating analysis of the visible color spectrum on pangolin karyotypes. Our results posited that pholidotes are closer to carnivores than to xenarthrans, which confirmed the current consensus that myrmecophagy in these mammalian lineages was more likely because of homoplasy (convergent evolution) than being an ancestral character. Since the modified CGH technique used is genome-wide, has chromosome-level resolution, and does not need full genome sequencing, it has considerable potential in systematics and other fields.     

Conflicts of Interest in Environmental Management: Estimating the Costs and Benefits of a Tree Invasion

Some alien tree species used in commercial forestry cause major problems as invaders of natural ecosystems. One such case, the black wattle tree, was introduced into South Africa from Australia in the 19th century. It is an important commercial species, as well as an aggressive invader, giving rise to significant environmental impacts and conflicts of interest. This paper provides an analysis of costs and benefits associated with this species in South Africa at a national level. The results suggest that a do nothing scenario (with no attempts being made to control the spread of the species beyond the limits of plantations) is not sustainable, as the benefit–cost ratio is around 0.4. The most attractive control option will be to combine physical clearing and plant-attacking biological control with the continuation of the commercial growing activities. In case this is not practically feasible the next best option is a combination of seed-attacking biological control, physical control and the development of secondary industries based on wood products from clearing programmes. There is, however, a 40% loss of benefits involved with this option when compared with the first best option. The techniques used in this study, and the findings relating to the scenarios that deliver the best returns on investment, should be of broad relevance to the problem of dealing with conflicts of interest relating to invasive alien plants that have commercial value.     

Evidence of hunting and hafting during the Middle Stone Age at Sibidu Cave, KwaZulu-Natal, South Africa: a multianalytical approach

Points and point fragments from Middle Stone Age layers (dated to between 50,000 and 60,000 years ago) from Sibudu Cave, KwaZulu-Natal, South Africa, were examined to establish whether they were used as hafted spearheads for hunting. A multi-analytical approach was followed, using macrofracture analysis, use-wear analysis, and residue analysis. In addition to the analytical processes, an experimental project tested the results of the macrofracture analysis on local raw materials. The study shows that points from Sibudu Cave were indeed hafted and used as hunting tools. It was further established that plant twine was probably the preferred binding material to attach the points to wooden hafts. Resin may have been used as an adhesive in combination with the binding material. A detailed examination of the ochre distribution on the points confirmed that ochre was also part of the hafting arrangement. The need to use a dependable methodology for the recognition of hunting and hafting traces on stone points from the southern African Middle Stone Age context is briefly discussed.     

Characterisation and Normalisation Factors for Life Cycle Impact Assessment Mined Abiotic Resources Categories in South Africa: The manufacturing of catalytic converter exhaust systems as a case study (10 pp)

Goal and Background Current Life Cycle Impact Assessment (LCIA) procedures have demonstrated certain limitations in the South African manufacturing industry. The aim of this paper is to propose new characterisation and normalisation factors for classified mined abiotic resource depletion categories in the South African context. These factors should reflect the importance of mined resources as they relate to region-specific resource depletion. The method can also be applied to determine global factors. Methods The reserve base (as in 2001) of the most commonly produced minerals in South Africa is used as basis to determine characterisation factors for a non-renewable mineral resources category. The average production of these minerals from 1991 to 2000 is compared to economically Demonstrated and Demonstrated Marginal Reserves (and not ultimate reserves) to obtain the characterisation factors in equivalence units, with platinum as the reference mineral. Similarly, for a non-renewable energy resources category, coal is used in South Africa as equivalent unit as it is the most important fossil fuel for the country. Crude oil and natural gas resources are currently obtained from reserves elsewhere in the world and characterisation factors are therefore determined using global resources and production levels. The normalisation factors are based on the total economic reserves of key South African minerals and world non-renewable energy resources respectively. A case study of the manufacturing of an exhaust system for a standard sedan is used to compare LCIA results for mined abiotic resource categories that are based on current LCIA factors and the new South African factors. Results and Discussion The South African LCIA procedure differs from current methods in that it shows the importance of other mined resources, i.e. iron ore and crude oil, relative to PGMs and coal for the manufacturing life cycle of the exhaust system. With respect to PGMs, the current characterisation factors are based on the concentrations of the metals in the ores and the ultimate reserves, which are erroneous with respect to the actual availability of the mineral resources and the depletion burden placed on these minerals is consequently too high. Conclusions The South African LCIA procedure for mined abiotic resources depletion shows the significance of choosing a method, which is inline with the current situation in the mining industry and its limitations. Recommendations and Outlook It is proposed to similarly investigate the impacts of the use of other natural resource groups. Water, specifically, must receive attention in the characterisation phase of LCIAs in South African LCAs.
