Grandmothers' Developmental Expectations for Early Childhood in Botswana.

Urban and rural grandmothers (n = 20) in Botswana participated in focus groups to learn their expectations for the acquisition of skills by preschool children. Their expectations for self-care, traditional politeness, and participation in household chores were dramatically earlier than developmental timetables reported for Western middle-class populations. There are some differences, however, in the urban and rural grandmothers' expectations. Rural grandmothers had earlier expectations for self-care skills and participation in household chores, and they had more specific expectations for mastering Setswana cultural customs. In addition, some urban grandmothers, who were generally more educated, described using more reciprocal communication, and they believed in playing with their grandchildren, whereas the rural grandmothers' communication was more instructional, and they insisted that children should play away from adults. Strikingly, there was no mention of school readiness goals or activities by either group, suggesting a "cultural misfit" between the standard early childhood curriculum, largely imported from the United States and other Western countries, and the cultural backgrounds of Batswana families. To create a more workable partnership between preschool teachers and grandparents-important caretakers of young children, both traditionally and currently-will require efforts to acknowledge and promote the values and expectations of both groups.

The Impacts of Conservation and Militarization on Indigenous Peoples : A Southern African San Perspective.

There has been a long-standing debate about the roles of San in the militaries of southern Africa and the prevalence of violence among the Ju/'hoansi and other San people. The evolutionary anthropology and social anthropological debates over the contexts in which violence and warfare occurs among hunters and gatherers are considered, as is the "tribal zone theory" of warfare between states and indigenous people. This paper assesses the issues that arise from these discussions, drawing on data from San in Angola, Namibia, Botswana, and Zimbabwe. Utilizing cases of how San have been affected by military forces and wildlife conservation agencies in what became protected areas in southern Africa, this article shows that indigenous peoples have been treated differentially by state and nongovernmental organizations involved in anti-poaching, shoot-to-kill, and forced resettlement policies. Particular emphasis is placed on the !Xun and Khwe San of southern Angola and northern Namibia and the Tshwa San of western Zimbabwe and northern Botswana, who have been impacted by militarization and coercive conservation efforts since the late nineteenth century. Principal conclusions are that conservation and militarization efforts have led to a reduction in land and resources available to indigenous people, higher levels of poverty, increased socioeconomic stratification, and lower levels of physical well-being. San have responded to these trends by engaging in social activism, forming community-based institutions, and pursuing legal actions aimed at obtaining human rights and equitable treatment.

Household access to traditional and indigenous foods positively associated with food security and dietary diversity in Botswana.

OBJECTIVE: To determine access to traditional and indigenous foods (TIF) and the association with household food security, dietary diversity and women's BMI in low socio-economic households. DESIGN: Sequential explanatory mixed-methods design, including a random household cross-sectional survey on household food insecurity access (HFIA), household dietary diversity (HDD) and women's BMI, followed by focus group discussions. SETTING: Two rural and two urban areas of Botswana. SUBJECTS: Persons responsible for food preparation or an adult in a household (n 400); for BMI, non-pregnant women aged 18-49 years (n 253). RESULTS: Almost two-thirds of households experienced moderate or severe food insecurity (28·8 and 37·3 %, respectively), but more than half of women were overweight or obese (26·9 and 26·9 %, respectively). Median HDD score was 6 (interquartile range 5-7) out of a total of 12. A positive correlation was found between number of TIF accessed and HDD score (r=0·457; P<0·001) and a negative correlation between number of TIF accessed and HFIA score (r=-0·272; P<0·001). There was no correlation between number of TIF accessed and women's BMI (r=-0·066; P=0·297). TIF were perceived as healthy but with declining consumption due to preference for modern foods. CONCLUSIONS: TIF may potentially have an important role in household food security and dietary diversity. There is need to explore potential benefits that may be associated with their optimal use on food security and nutrition outcomes.

Appropriating social citizenship: women's labour, poverty, and entrepreneurship in the manual workers union of Botswana.

Interrogating critiques of the 'African labour aristocracy' thesis, the article proposes that public service industrial-class manual workers in Botswana form, if not a labour 'aristocracy' in the sense first defined by Saul and Arrighi, then a marginal worker 'elite'. They are privileged in having a regular salary above minimum pay, augmented by periodic lump-sum gratuity payments. This sets them apart from the other low-paid workers in the private sector, casual workers in the informal economy and a vast army of unemployed job seekers. In the absence of a national unemployment benefit scheme in Botswana, the article explores some of the strategies deployed by women members of the Manual Workers Union in their attempts to contend with the spectre of future unemployment and impoverishment. In gender terms, the article highlights the independence, autonomy and decision-making capacity of women trade unionist leaders, who straddle the worlds of workers' rights and citizens' rights, and manoeuvre their way through the maze of rules and regulations they encounter in both.

Pre-colonial culture, post-colonial economic success? The Tswana and the African economic miracle.

Cultural explanations of economic phenomena have recently enjoyed a renaissance among economists. This article provides further evidence for the salience of culture through an in-depth case study of one of the fastest-growing economies in the world during the last 50 years-Botswana. The unique culture that developed among the Tswana before and during the early days of colonialism, which shared many features with those of western nation-states, appears to have contributed significantly to the factors widely seen as determinants of Botswana's post-colonial economic success: state legitimacy, good governance and democracy, commercial traditions, well-established property rights, and inter-ethnic unity. Neighbouring Southern African cultures typically did not exhibit these traits.

Grandmothers' productivity and the HIV/AIDS pandemic in sub-Saharan Africa.

The human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) pandemic has left large numbers of orphans in sub-Saharan Africa. Botswana has an HIV prevalence rate of approximately 40% in adults. Morbidity and mortality are high, and in a population of a 1.3 million there are nearly 50,000 children who have lost one or both parents to HIV/AIDS. The extended family, particularly grandparents, absorbs much of the childrearing responsibilities. This creates large amounts of additional work for grandmothers especially. The embodied capital model and the grandmother hypothesis are both derived from life history theory within evolutionary ecology, and both predict that one important factor in the evolution of the human extended family structure is that postreproductive individuals such as grandmothers provide substantial support to their grandchildren's survival. Data collected in the pre-pandemic context in a traditional multi-ethnic community in the Okavango Delta of Botswana are analyzed to calculate the amount of work effort provided to a household by women of different ages. Results show that the contributions of older and younger women to the household in term of both productivity and childrearing are qualitatively and quantitatively different. These results indicate that it is unrealistic to expect older women to be able to compensate for the loss of younger women's contributions to the household, and that interventions be specifically designed to support older women based on the type of activities in which they engage that affect child survival, growth, and development.

Genotypic characterization of Kaposi's sarcoma-associated herpesvirus in asymptomatic infected subjects from isolated populations.

Molecular epidemiological studies of Kaposi's sarcoma-associated herpesvirus (KSHV) have concentrated on characterization of viral strains in tumour biopsy samples from Kaposi's sarcoma (KS) patients, mostly obtained in the United States and Europe. Tumour biopsies are a convenient source of viral DNA, as they have a high viral load compared to peripheral blood. However, sequences obtained from biopsies may not be representative of viral strains in asymptomatic subjects and information on ethnicity is often not available. Here, a population-based approach has been used to study the molecular and seroepidemiology of KSHV in isolated populations in Ecuador and Botswana. Amerindians in Ecuador had a variable prevalence of KSHV and all strains characterized were of subtype E, based on K1 sequencing. All Amerindian strains had predominant (P)-type K15 alleles and had sequences in both T0.7 and ORF 75 that appeared to be characteristic of these strains. The prevalence of KSHV in two ethnic groups in Botswana was extremely high. K1 sequences from both Bantu and San subjects were mostly of subtypes B and A5, which are typical of African KSHV strains, but the sequence from one San subject did not cluster with any known subtype. Considerable heterogeneity was seen in the T0.7 and ORF 75 genes in the San subjects and one had a minor (M)-type K15 allele. The heterogeneity of the KSHV strains found in these subjects from Botswana contrasts with the homogeneity of KSHV strains in Amerindians, reflecting differences in the evolutionary history of these populations.

Prevalence of occupational lung disease among Botswana men formerly employed in the South African mining industry.

OBJECTIVE: To determine whether previous health experiences affect the prevalence of occupational lung disease in a semirural Botswanan community where there is a long history of labour recruitment to South African mines. METHOD: A cross sectional prevalence study of 304 former miners examined according to a protocol including a questionnaire, chest radiograph, spirometry, and medical examination. RESULTS: Overall mean age was 56.7 (range 28-93) years, mean duration of service 15.5 (range 2-42) years. 26.6% had a history of tuberculosis. 23.3% had experienced a disabling occupational injury. Overall prevalence of pnemoconiosis (> 1/0 profusion, by the International Labour Organisation classification) was 26.6%-31.0%, and 6.8% had progressive massive fibrosis (PMF). Many were entitled to compensation under South African law. Both radiograph readers detected time response relations between pneumoconiosis and PMF among the 234 underground gold miners. PMF could result from < 5 years of exposure, but was not found < 15 years after first exposure. Both pulmonary tuberculosis (PTB) and pneumoconiosis were found to be associated with airflow limitation. CONCLUSIONS: Former miners in Botswana have a high prevalence of previously unrecognised pneumoconiosis, indicative of high previous exposures to fibrogenic respirable dust. Their pneumoconiosis went unrecognised because they had no access to surveillance after employment. Inadequate radiographic surveillance or failure to act on results when employed or when leaving employment at the mines could have contributed to under recognition. Community based studies of former miners are essential to fully evaluate the effects of mining exposures. Our findings indicate a failure of established measures to prevent or identify pneumoconiosis while these miners were in employment and show that few of the social costs of occupational lung diseases are borne by mining companies through the compensation system.

Change in the prevalence of active pulmonary tuberculosis discovered at autopsy in black miners.

The prevalence of active pulmonary tuberculosis at autopsy in two groups of Black miners who had died while working on the mines during the periods 1961-1963 and 1974-1978 was investigated. Radiographs had been taken regularly in both groups while they were alive to detect early tuberculous lesions. If any such lesions were found, the worker was excluded from the populations which were being studied. A highly significant secular decrease in the prevalence of active pulmonary tuberculosis was found. Possible explanations for this finding are discussed and it is concluded that there may be a decline in the incidence of tuberculosis in Blacks.

Effect of vitamin C supplementation on black mineworkers.

Subclinical vitamin C deficiency frequently occurs in Black mineworkers, in spite of an apparently adequate daily intake. A study was undertaken to establish the minimum rate of supplementation that would effectively reduce the incidence of subclinical vitamin C deficiency. Two levels of supplementation were tested in relation to a control group. It was found that a supplementation rate of at least 235 mg/head/day is required to maintain reasonably adequate serum levels. It was also found that effective control measures are required to ensure that the supplement is added to the magou, the staple beverage of the miners. It is strongly recommended that the intake of every Black mineworker be supplemented at a rate of 200 - 250 mg/day.
