Theoretical perspectives on cinema in Africa: Culture,identity and Diaspora

The study of African cinema is often assumed to be the study of black film. This paper examines this notion with respect to definitions of Africa, questions of identity, and different historical discourses of resistance. Western psychocentric approaches to film criticism are criticized. The issue of authorship is revisited with the question: Can a white director make a film reflecting the “black” experience? This question is explored with reference to debates about Spike Lee's Malcolm X and South African director Oliver Schmitz's Mapantsula. In the process, J examine how meanings are articulated and rearticulated in specific contexts by both those who define them and audiences which interpret them. The articulations of “race wars” in the USA and South Africa respectively are discussed, as is the relationship between race and class in the anti‐apartheid struggle. The disarticulation of Black Consciousness in South Africa from its popularizer, Steve Biko, by film activists in the Mass Democratic Movement during the 1980s, provides a background for the emergence of “non‐racial” cinema. Reception is suggested as a more subtle means of film categorisation. Mapantsula, for example, though made by a mainly white crew, is understood by black audiences to be a film accurately reflecting the experience of the black oppressed in South Africa. Though reception is a dynamic response, shifting and responding to historical trajectories and new discourses, with interpretations fragmenting between different classes and class fractions at different times, such a strategy for area and cultural classification of films avoids the pitfalls of categories based on ideology, myth, race and language.     

Sexual risk behaviour among the youth in the era of HIV/AIDS in South Africa

The paper discusses factors associated with sexual risk behaviour, i.e. failure to use condoms consistently during sexual intercourse, among unmarried sexually experienced youths in South Africa. Data from the 'Transitions to Adulthood in the Context of AIDS in South Africa' surveys of 1999 and 2001 were analysed to identify factors associated with high sexual risk behaviour among the youth. The multinomial regression models for male and female youths were fitted separately for the 1999 and 2001 data sets. The results show increasingly consistent use of condoms during sexual intercourse and that high sexual risk behaviour among youths is predominantly determined by social factors such as 'ever-pregnant' or 'ever made pregnant', 'ever given something for sex', age of sexual partner, currently in school, pressured by friends to have sex, peer influence on safe sex and education level for males. There is evidence that availability of contraception information is important in strategic interventions that seek to change the sexual behaviour of the youth in South Africa.     

Clonality in South African isolates and evidence for a European origin of the root pathogen Thielaviopsis basicola

Thielaviopsis basicola is a soil-borne fungal pathogen with a wide host range and a cosmopolitan distribution. It causes disease on many agricultural crops, and in South Africa is the causal agent of black pod rot of groundnuts and black root rot on chicory. Knowledge of the population diversity of T. basicola could provide valuable information regarding management strategies, the possible movement, origin, and reproductive strategies of the fungus. The objective of this study was to determine the population diversity of T. basicola isolates from groundnuts and chicory in South Africa using co-dominant polymorphic markers. These markers were also used to compare isolates from South Africa with those from other hosts and geographic regions. Seven loci revealed nine alleles and two genotypes, one on groundnut and one on chicory, differing at only two loci. T. basicola isolates from eight different countries and ten different hosts revealed 17 genotypes across the seven loci with 39 different alleles. The lack of diversity for the two South African host-related populations of isolates suggests that T. basicola was introduced into South Africa. Some evidence is provided for a European origin of the pathogen, possibly linked to trade in root crops.     

An assessment of sex using the skull of black South Africans by discriminant function analysis

The derivation of discriminant function equations for skeletal elements of South African populations continues to be an area of interest to both forensic anthropologists and skeletal biologists alike. The skull of black South Africans has previously been subjected to discriminant function analysis, using four measurements and two indices; however, no equations were derived to address the issue of sex determination. Recently Franklin, Freedman and Milne [2005. Sexual dimorphism and discriminant function sexing in indigenous South African crania. HOMO J. Comp. Hum. Biol. 55, 213-228] used the crania of black South Africans, in a three-dimensional approach, with eight linear measurements to investigate sex determination. This study, although valuable, requires the use of highly technical and expensive morphometric equipment that renders it less feasible in South Africa. In response to this, our study uses traditional anthropometric measurements and equipment to address the question of sex determination from the crania and mandible of blacks. One hundred and twenty non-pathological skulls were randomly selected from the Raymond Dart Collection of Human Skeletons, equally distributed by sex and belonging to individuals whose age at death ranges between 25 and 70 years. Fourteen cranial and six mandibular measurements were subjected to discriminant function analyses and discriminant function equations were derived for sex determination. Average accuracies ranged between 80% and 85% and were on par with that obtained in previous studies. Our study shows that traditional methods provide average accuracies that are comparable to those obtained using more complex techniques.     

The impact of black wattle encroachment of indigenous grasslands on soil carbon,Eastern Cape,South Africa

Black wattle (Acacia mearnsii, De Wild.) is a fast growing tree species introduced into South Africa in the nineteenth century for commercial purposes. While being an important source of timber and firewood for local communities, black wattle is an aggressive invasive species and has pervasive adverse environmental impacts in South Africa. Little is known about the effects of black wattle encroachment on soil carbon, therefore the aim of this study was to investigate the impact of black wattle encroachment of natural grassland on soil carbon stocks and dynamics. Focussing on two sites in the Eastern Cape, South Africa, the study analysed carbon stocks in soil and litter on a chronosequence of black wattle stands of varying ages (up to >50 years) and compared these with adjacent native grassland. The study found that woody encroachment of grassland at one site had an insignificant effect on soil and litter carbon stocks. The second site showed a clear decline in combined soil and litter carbon stocks following wattle encroachment. The lowest stock was in the oldest wattle stand, meaning that carbon stocks are still declining after 50 years of encroachment. The results from the two sites demonstrate the importance of considering changes in soil carbon when evaluating ecosystem effects of invasive species.     

Make Afrikaners great again! National populism,democracy and the new white minority politics in post-apartheid South Africa

This article on national populism in South Africa brings a view from the South to scholarship overwhelmingly concentrated on the north Atlantic and European world. While in white majority contexts, national populism seeks to capture formal political power, the white minority’s lack of political leverage in post-apartheid South Africa sees an assertion of white autonomy emerge in the civil society arena. The article examines the discursive strategies of the Solidarity Movement, a broad-based social movement which claims to represent the white minority, particularly white Afrikaans-speakers, amid black majority rule. It shows how through a reinvention of the past, recasting of race, and reformulation of nationalist narratives by neoliberal logics the Movement discursively undermines black majority rule, and seeks to create spaces in which white privilege, power and identities are maintained. These findings provide new insights into the relation between populism and democracy, and hold important lessons for the increasingly multicultural global North.     

Epidemiology of congenital heart disease in Louisiana: an association between race and sex and the prevalence of specific cardiac malformations.

We hypothesized that susceptibility to the genetic and environmental factors that disrupt cardiac development is associated with race and sex. To evaluate this hypothesis, we asked whether the prevalence of specific cardiac malformations differs by race and sex. We attempted to include all infants born alive in the State of Louisiana from January 1, 1988, through December 31, 1989, and diagnosed by echocardiography, catheterization and/or autopsy within a year of birth as having one of ten specific cardiac malformations. The prevalence of atrioventricular canal defects (AVCD) per 1,000 live births was significantly higher for black females (.744) compared to black males (.198) and for white females (.414) compared to white males (.116). Complete transposition of the great arteries (TGA) was significantly higher for white males (.559) compared to white females (.122); in contrast, TGA was not significantly different for black males (.198) and black females (.169). Obstructive left heart syndrome (OLHS)--aortic stenosis and/or coarctation of the aorta--was significantly higher for white males (.652) compared to white females (.317); in contrast, OLHS was not significantly different for black males (.264) and black females (.169). Single ventricle (SV) was significantly higher for whites (.202) compared to blacks (.067). We did not find that race and sex were associated with differences in the prevalence of tetralogy of Fallot and hypoplastic left heart syndrome. The numbers of infants with anomalous pulmonary venous return, tricuspid atresia, double outlet right ventricle, or truncus arteriosus were too small to measure an association with race and sex. These results demonstrate that the prevalence of a subset of cardiac malformations differs by race and sex.(ABSTRACT TRUNCATED AT 250 WORDS)     

Influence of environmental conditions on sex allocation in the black rhinoceros population of Mkhuze Game Reserve,South Africa

According to the Trivers–Willard and local resource competition (LRC) hypotheses, for species where reproductive success is more variable in one sex, natural selection may lead to a bias in sex allocation of a female’s offspring according to her body condition. The extrinsic modification hypothesis (EMH) suggests that offspring sex can also be influenced by environmental conditions experienced by mothers. We investigated the influence of rainfall, El Niño‐Southern Oscillation (ENSO), population size and burning, in the year before conception and during pregnancy, on sex allocation in the black rhinoceros population of Mkhuze Game Reserve, South Africa, during 1970–2007. Females were more likely to have a male calf as rainfall during pregnancy increased, supporting the Trivers–Willard hypothesis. Also, the probability of having a male calf increased with population size, supporting the LRC hypothesis. Calf sex allocation was not influenced by ENSO. In conclusion, local environmental conditions may influence sex allocation in black rhinoceros, thereby supporting the EMH. Burning and population size may influence sex allocation in black rhinoceros, and yet can be manipulated by managers. Thus, this knowledge can be applied to improve population structure assessments and management regimes, especially in enclosed reserves, which is essential to maintain endangered species’ productivity.     

Renal weights in the southern African black population

Renal weights of 430 adult black subjects coming to medicolegal autopsy at the Diepkloof State Mortuary, a large urban area southwest of Johannesburg, South Africa, were analyzed. The subjects were from 10 southern African black ethnic groups-Zulu, Sotho, Tswana, Xhosa, Shangaan, Swazi, Venda, Ndebele, Kalanga, and Malawi. The aims of the study were: 1) to ascertain the anatomical "norm" as it pertains to renal weights in this diverse population group; 2) to formulate standard reference tables that might be of use to the practicing pathologist in the southern African arena; 3) to provide a range of values that take into account the variables of age, sex, race, body weight, and body height; and 4) to provide a standard of comparison with anthropological and anatomical studies conducted on North American black, North American Caucasian, Indian subcontinent, Burmese, and Jamaican population groups. In each of the 430 subjects, age, sex, ethnic group, supine body length, body weight, individual left and right renal weights, and causes of death were noted. The latter were divided into 6 categories: 1) penetrating incised wounds; 2) multiple injuries; 3) gunshot wounds; 4) craniocerebral injuries; 5) various miscellaneous nonnatural causes of death; and 6) natural causes of death. The above variables were analyzed by computer and compared with respect to renal weights. No statistically significant differences were observed between the sexes or the age groups.(ABSTRACT TRUNCATED AT 250 WORDS)     

Sex and race differences in finger ridge-count correlations

Correlations between ridge-counts on the ten fingers were compared by race and sex in 11 samples representing Negroes and Caucasians: five from subsaharan Africa, one American Black, three European, one American White and one from India. The samples of European ancestry showed no consistent sex difference in mean correlation, although female American Whites significantly exceeded males. In three of the six Negro samples and in the Parsis of India males showed significantly higher average correlations than females. The pattern of sex and race differences suggests that the sex chromosomes, particularly the Y chromosome, play a role in dermal ridge development.     

The Meaning of ‘Self-Starvation’ in Impoverished Black Adolescents in South Africa

Recent surveys in South Africa have demonstrated that disordered eating is equally common among black and white female students. Self-report measures have been used in these surveys to establish levels of disordered eating. One study in Tanzania, where a two-stage design was implemented, showed that upon interview the majority of participants did not present with disordered eating. The absence of two-stage studies in South Africa brings into question some of the findings from these surveys. In the present study, we surveyed a sample of black and white high school students in South Africa to establish the prevalence of disordered eating. In the second phase of this study, we attempted to interview those black students from one particular school who scored high on the eating disorder measures. This process proved both challenging and elucidating. While a significant number of young black females endorsed eating disorder symptoms on self-report, interviews with some participants showed that self-starvation and related symptoms had a different meaning from what we would typically expect from someone with an eating disorder. Consequently, this study highlights the need to revisit the methods typically employed in cross-cultural research in eating disorders. Careful consideration of a variety of cultural factors that may alter the meaning of standard measures is called for.     

Relatedness and investment in children in South Africa

Investment in children is examined using a nationally representative sample of 11,211 black (African) households in South Africa. I randomly selected one child from each household in the sample and calculated the average genetic relatedness of the other household members to the focal child. Using multivariate statistical analysis to control for background variables such as age and sex of child, household size, and socioeconomic status, I examine whether the coefficient of relatedness predicts greater household expenditures on food, on health care, and on children’s clothing. I also test whether relatedness is associated with health and schooling outcomes. The results are consistent with an inclusive fitness model: Households invest more in children who are more closely related. Two exceptions were found: in rural areas, genetic relatedness was negatively associated with money spent on food and on health care. Explanations for these results are discussed. Preliminary versions of this paper were presented at the 2003 Human Behavior and Evolution Society annual meeting in Lincoln, Nebraska, and at the 2003 Human Behavioral Ecology Workshop in Bangor, Maine.

Patella measurements of South African whites as sex assessors.

This study uses metrical characteristics of the patella to derive population specific equations for sex determination in South Africa. Six measurements were taken from 120 normal and undamaged left patellae in a sample of known race, equally distributed by sex, obtained from the Raymond A Dart collection of human skeletons. These data were subjected to discriminant analysis. Maximum height and maximum breadth were selected in the stepwise analysis with an average accuracy of 83% in correct sex classification. Four functions were derived from the direct analysis with a range of average accuracy between 77% and 85%. While most individual variables showed high misclassification rates and may not be useful on their own, maximum height and maximum breadth have an average accuracy of 85 and 79%, respectively.     

Geophagy in chacma baboons: patterns of soil consumption by age class, sex, and reproductive state

Despite baboons' widespread distribution across Africa, geophagy among all subspecies has been poorly documented. We used video camera traps and soil analyses to investigate geophagy in chacma baboons (Papio cynocephalus ursinus) inhabiting the Western Cape of South Africa. During an 18‐month study, from August 2009 to January 2011, we continually monitored the largest and most frequently visited geophagy sites with camera traps for 545 days and captured soil consumption at one or more sites on 266 of those days (49%). In 3,500 baboon visits to geophagy sites, video camera traps captured 58.6 hr of geophagy. From these data, we evaluated site preference based on time spent consuming soil among these four geophagy sites. One hundred and seventy days of soil consumption data from the most frequently visited geophagy site allowed us to look for demographic trends in geophagy. Selected consumed soils from geophagy sites were analyzed for mineral, physical, and chemical properties. The baboons spent more time consuming white alkaline soils with high percentages of clay and fine silt, which contained higher concentrations of sodium than non‐white acidic soils that contained higher concentrations of iron. Our data indicate that pregnant chacma baboons spent more time consuming soil at monitored geophagy sites than baboons of any other age class, sex, or reproductive state. Based on analytical results, the soils consumed would be effective at alleviating gastrointestinal distress and possibly supplementing minerals for all age/sex classes, but potentially for different age/sex requirements.

Life expectancy of the 20th century Venda: A compilation of skeletal and cemetery data

Little information is available on the 20th century mortality rates of rural black South African groups, such as the Venda. The purpose of this study was to apply abridged life tables in order to estimate life expectancy from both skeletal remains and death registry information of modern South African communities. Comparisons were also made with prehistoric and contemporary groups as a means to better evaluate life expectancy for this time period. The sample consisted of 160 skeletons of known Venda origin and burial registry information for 1364 black South Africans from the Rebecca Street and Mamelodi Cemeteries in Pretoria, South Africa. Standard anthropological techniques were applied to determine sex and estimate age from the skeletal remains. The stationary and non-stationary life table models were used to analyse the data. A high rate of child mortality, low juvenile and adult mortality with a steady increase in mortality after the age of 30 years was observed for both the Venda and the cemetery samples. Throughout the 20th century, life expectancy was shown to increase for black South Africans. However, due to the widespread HIV infection/AIDS of the 21st century, infant and young adult mortality rates continue to rise at such a speed that the decline in mortality seen for South Africans in the last 50 years will most likely to be lost in the next decade due to this disease.     

Paternal effects on the human sex ratio at birth: evidence from interracial crosses

The effects of interracial crossing on the human sex ratio at birth were investigated using United States birth-certificate data for 1972-1979. The sex ratio was 1.059 for approximately 14 million singleton infants born to white couples, 1.033 for 2 million born to black couples, and 1.024 for 64,000 born to American Indian couples. Paternal and maternal race influences on the observed racial differences in sex ratio were analyzed using additional data on approximately 97,000 singleton infants born to white-black couples and 60,000 born to white-Indian couples. After adjustment for mother's race, white fathers had significantly more male offspring than did black fathers (ratio of sex ratios [RSR] = 1.027) and Indian fathers (RSR = 1.022). On the other hand, after adjustment for father's race, white mothers did not have more male offspring than did black mothers (RSR = 0.998) or Indian mothers (RSR = 1.009). The paternal-race effect persisted after adjustment for parental ages, education, birth order, and maternal marital status. The study shows that the observed racial differences in the sex ratio at birth are due to the effects of father's race and not the mother's. The study points to paternal determinants of the human sex ratio at fertilization and/or of the prenatal differential sex survival.     

Comparison of the prevalence of type A behavior in boys and girls from two contrasting socioeconomic status groups

The prevalence of Type A behavior in children from lower-class rural and upper-class urban backgrounds was compared using the Hunter-Wolf A-B Self-Rating Scale (H-W A-B). Analyses of variance were performed for two levels of socioeconomic status (SES), two levels of race (black and white), two levels of gender, and two levels of age (9-11 and 13-14). A significant difference for SES was found in the predicted direction with a greater prevalence of Type A being found among upper-urban children (p less than .001). There was also a significant effect for race (p less than .0001). Although there was a significant effect for gender with boys scoring higher (p less than .001), there was no difference between boys and girls within either SES group, and both boys and girls in the upper-urban group were more Type A than boys and girls in the lower-rural group (p less than .001). The possibility that the lack of sex differences within groups may reflect changing lifestyles for young women is discussed as a topic worthy of further epidemiological investigation.     

Hyperracialized: interracial relationships in post-apartheid South Africa and the informal policing of public spaces

Dynamics of race in South Africa are deeply entangled within a world system that continues to enable hegemonic white privilege. Prevalent views and behaviours towards “interracial” relationships reveal a rebellion against the non-racial philosophies and policies of the new government and are an indicator of the ongoing salience of race in shaping lived experience. Drawing on interviews with couples in so-called “interracial” relationships, this article argues that unequal power dynamics continue to hyperracialize and regulate these relationships through “privatized” racial boundary policing, even though such relationships are no longer stigmatized and criminalized by the state as in apartheid South Africa. Their experiences of racism show up in two distinct ways: aggressive policing and covert policing; these in turn can lead to self-policing, and perpetuate racial social organization.     

Assessing introgressive hybridization between blue wildebeest (<Emphasis Type="Italic">Connochaetes taurinus</Emphasis>) and black wildebeest (<Emphasis Type="Italic">Connochaetes gnou</Emphasis>) from South Africa

Introgressive hybridization poses a threat to the genetic integrity of black wildebeest (Connochaetes gnou) and blue wildebeest (Connochaetes taurinus) populations in South Africa. Black wildebeest is endemic to South Africa and was driven to near extinction in the early 1900s due to habitat destruction, hunting pressure and disease outbreaks. Blue wildebeest on the other hand are widely distributed in southern and east Africa. In South Africa the natural distribution ranges of both species overlap, however, extensive translocation of black wildebeest outside of its normal distribution range in South Africa have led to potential hybridization between the two species. The molecular identification of pure and admixed populations is necessary to design viable and sustainable conservation strategies, since phenotypic evidence of hybridization is inconclusive after successive generations of backcrossing. The aim of this study was to assess levels of hybridization in wildebeest using both species-specific and cross-species microsatellite markers. Black wildebeest (157) and blue wildebeest (122) from provincial and national parks and private localities were included as reference material, with 180 putative hybrid animals also screened. A molecular marker panel consisting of 13 cross-species and 11 species-specific microsatellite markers was developed. We used a Bayesian clustering model to confirm the uniqueness of blue- and black wildebeest reference groups, assign individuals to each of the two clusters, and determine levels of admixture. Results indicated a clear partition between black wildebeest and blue wildebeest (the average proportions of membership to black wildebeest and blue wildebeest clusters were QI?=?0.994 and QI?=?0.955 respectively). From the putative hybrid samples, only five hybrid individuals were confirmed. However, high levels of linkage disequilibrium were observed in the putative hybrid populations which may indicate historical hybridization. Measures of genetic diversity in the black wildebeest populations were found to be lower than that of the blue wildebeest. The observed lower level of genetic diversity was expected due to the demographic history of the specie. This study will make a significant contribution to inform a national conservation strategy to conserve the genetic integrity of both species.     

New human teeth from Middle Stone Age deposits at Klasies River, South Africa

Since 1984, the main site at Klasies River has been re-investigated. Human remains, animal bones and stone artefacts have been collected from the LBS, SAS and other stratigraphic members, and these discoveries help to establish the antiquity of anatomically near-modern populations practicing a Middle Stone Age way of life on the southern coast of Africa. Several teeth found in the lower SAS levels in 1989-1991 can be matched in recent South African populations. Two complete upper molars representing one individual have crowns that are relatively short mesiodistally. These specimens are small in comparison to black South African homologues, but MD and BL dimensions fall close to the averages for San burials. This evidence confirms that several of the Klasies individuals have very small molars, while others have cheek teeth that are close to the upper limits for size variation in recent Africans. The new material is in keeping with the view that sex dimorphism within this Middle Stone Age population may be pronounced.
