Abstract: A new record of Crambionella stuhlmanni is reported from the east coast of South Africa. The material is described using quantitative morphological data, and mitochondrial (CO1) and nuclear (ITS-1) sequence data. The species can be diagnosed by a combination of morphological features including the presence of conical projections on velar lappets, the absence of orbicular appendages among mouthlets and the short length of the terminal club on the oral arm. Mitochondrial sequence data unambiguously delineate C. stuhlmanni as a separate species from C. orsini, and phylogenetic analyses support its placement within the monophyletic genus, Crambionella URI: http://hdl.handle.net/10566/249 Files in this item: 1

Abstract: This essay enquires into the depictions of Justice through the ages, as well as the myths surrounding these depictions, more particularly in Egypt, Greece, and Rome, as well as in modern times. The essay departs in significant respects from traditional interpretations by seeking to gain from the insights in relation to mythology and the use of symbols provided by psychoanalysis, structuralism, Heidegger’s thinking on Being, and deconstruction. Insofar as psychoanalysis is concerned, of importance in the present context is Freud’s analysis of symbolism in the interpretation of dreams and in myths, specifically insofar as he contends that the symbols employed there almost invariably have a sexual connotation. The approach of Claude Lévi-Strauss is the focus of the detour through structuralism, with Lévi-Strauss challenging certain of the most prevalent ideas in relation to myth, such as that there is some original version of a myth, usually believed to be the earliest version. In the case of Heidegger, of particular importance is his challenge to us “moderns” to not be too quick in our belief that we understand ancient texts or the ancient conceptions of deities. He more specifically places in question the common belief that the gods and goddesses are persons or that they are abstract personifications of concepts. Derrida, in his analysis of the texts of Freud, Lévi-Strauss and Heidegger, further develops the ideas of each of these thinkers, seeking thereby to go beyond the Oedipus complex, beyond the security of structure, and beyond Being. After an analysis of depictions of the goddesses Ma’at, Themis, Dike and Justitia, based on the insights gained in the preceding analysis, the essay concludes with a reading of the blindfold of Justice in her modern guise which seeks to exceed metaphysics. Drawing specifically on Derrida’s analysis of blindness in drawing, it arrives eventually not at the essence, but the an-essence of justice. URI: http://hdl.handle.net/10566/288 Files in this item: 1

Abstract: This paper considers the role of ‘measurement’ and other forms of poverty knowledge in a context where the nature and direction of global economic growth is creating ‘surplus populations’ suffering various forms of marginalisation in the global economy. It links the development of different forms of poverty knowledge with the ways in which states and non-state agents seek to ‘govern’ poverty and poor populations, and with the ‘biopolitics’ whereby calculations are made about the differential allocation of resources towards different sectors of the global population. The paper argues that addressing the root causes of poverty requires social actors to go beyond the narrow limits of institutionally sanctioned and bureaucratically invested ‘poverty knowledge’ that currently dominate policy thinking. Rather than seeking to understand poverty by measuring the characteristics of members of populations, they should try to understand poverty as an aspect of social relations, and try to come to grips with differential insertion of populations in the fields of force of modern globalised capitalism. Analysis should abandon simple notions of ‘marginalisation, and come to grips with the agency of poor people and the complex relationships between informality, marginality, exclusion and incorporation. Ultimately, however, a more nuanced understanding of the role of poverty knowledge in present day biopolitics does not bring with it any easy answers: rather, it challenges applied social scientists to be more aware of the responsibilities they bear as producers of 'useful' knowledge in a time of increased global instability.

Abstract: This contribution explores John Calvin's position on natural theology. The point of departure is not so much the much discussed notions of a sensus divinitatis or of the semen religionis, but the role played by the human senses in coming to knowledge of God in the first place. How can God's presence be recognised? How can human language (that which is natural), from below, express the inexpressible? How is it possible to speak of God in the first place? This article suggests that Calvin's remarkably sophisticated understanding of signification is the clue to respond to these questions. His position is discussed on the basis of the reading strategy of catena and commentary. The author finally offers some concluding observations on the relationship between signifier, signified and referent in human language about God.

Abstract: This article investigates the tensions in the "mode 2" thesis, which suggests the emergence of new, global trends in the production and dissemination of knowledge. I explain its influence in recent South African higher education policy debates and research practices by referring to competing readings of "mode 2", which have allowed it to feed simultaneously into both liberal and critical discourses on higher education transformation in South Africa. Clear tensions emerge from the limitations of "mode 2" in speaking to existing inequalities and in informing non-corporate models of institutional transformation.

Abstract: Background. No pharmacokinetic data exist for premature infants receiving single-dose nevirapine (sd NVP) for prevention of mother-to-child transmission (MTCT) of HIV. Aim. To describe NVP decay pharmacokinetics in two groups of premature infants - those whose mothers either received or did not receive NVP during labour. Methods. Infants less than 37 weeks' gestation were prospectively enrolled. Mothers received sd NVP during labour if time allowed. Infants received sd NVP and zidovudine. Blood was collected on specified days after birth and NVP concentrations were determined by liquid chromatography-mass spectrometry. Results. Data were obtained from 81 infants, 58 born to mothers who received sd NVP during labour (group I) and 23 to mothers who did not receive NVP (group II). Of the infants 29.6% were small for gestational age (SGA). Median (range) maximum concentration (Cmax), time to reach maximum concentration (Tmax), area under the plasma concentration-time curve (AUC) and halflife (T) were 1 438 (350-3 832) ng/ml, 25h50 (9h40-83h45), 174 134 (22 308-546 408) ng×h/ml and 59.0 (15.4-532.6) hours for group I and 1 535 (635-4 218) ng/ml, 17h35 (7h40-29h), 168 576 (20 268-476 712) ng×h/ml and 69.0 (22.12-172.3) hours for group II. For group II, the median (range) volume of distribution (Vd) and body clearance (Cl) were 1 702.6 (623.7-6 189.8) ml and 34.9 (6.2-163.8) ml/h. The AUC was higher (p=0.006) and Cl lower (p<0.0001) in SGA infants. Plasma concentrations exceeding 100 ng/ml were achieved over 8 days in 78% infants in group I and 70.0% in group II. The MTCT rate was 4.8%. Conclusion. Women in preterm labour often deliver with little advance warning. Our study suggests that NVP dosing of preterm infants as soon as possible after birth without maternal intrapartum dosing may be as effective as combined maternal and infant dosing.

Abstract: Diel vertical migration (DVM) of six common species of hydromedusae was investigated during two drogue studies conducted in St Helena Bay on the west coast of South Africa in February 1995. Clytia spp., Obelia spp. and Bougainvillia macloviana, were largely confined to surface waters and did not appear to display any DVM. By contrast, Leuckartiara octona and Euphysa aurata displayed clear DVM and, like Proboscidactyla menoni, were found at greater depths than the other species. The depth distribution and amplitude of migration varied between surveys for most species, so definitive interpretations of patterns could not be made.

Abstract: A new species of Magelonidae, Magelona debeerei sp. nov., is described and illustrated from grab-samples collected at <100moff the southwest coast of Africa. Magelona debeerei sp. nov. has previously been identified from the region as M. papillicornis (Müller, 1858) by Day (1955, 1961, 1967) but differs from M. papillicornis sensu stricto by possessing dorsal medial lobes on chaetigers 4–8 and lateral pouches (Σ configuration) between chaetigers 10 and 11. Three species of Magelona have now been recorded from southern Africa (M. capensis Day, 1961, M. cincta Ehlers, 1908 and M. debeerei sp. nov.), and a key to Magelona from this region is provided.

Hart, Genevieve (Library and Information Association of South Africa, 2010)[more][less]
Abstract: The article reflects on a case study of a group of six school-based dual use libraries in rural South Africa – focusing specifically on their community role. Its starting point is the library and information services (LIS) Transformation Charter’s vision of public libraries that play a meaningful role in the attainment of the Millennium Development Goals. The study employed a mix of data gathering methodologies – interviews, observation and analysis of documents. The key question that emerges from the study relates to the rather low usage of the libraries by the adults in the surrounding villages. All six libraries claim to provide “access” but it is not clear what they provide access to. The study suggests that a sharper focus on their community information services is required. More leadership, staff education and focused programming might enable the libraries to fulfil their exciting potential. URI: http://hdl.handle.net/10566/250 Files in this item: 1

Abstract: The relevance of the Non-Aligned Movement has been in question since the end of Cold War bipolarity. In the post-Cold War order, whether interpreted as cosmopolitan, unipolar, multipolar or globalised in nature, there are still challenges to the main purpose of the Non-Aligned Movement, which can be defined as the pursuit of self-determination and development for so-called Third World states. The rise of China is impacting on the current world order, possibly returning it to a kind of bipolarity, which the Non-Aligned Movement members can exploit. In addition, the 'Beijing Consensus' may provide new terms on which developing countries can be integrated into the global economy in a way that would accommodate and encourage their development.

Abstract: Interviews conducted in South Africa found that awareness of antiretroviral therapy was generally poor. Antiretroviral drugs were not perceived as new, but one of many alternative therapies for HIV/AIDS. Respondents had more detailed knowledge of indications, effects and how to access alternative treatments, which is bolstered by the active promotion and legitimization of alternative treatments. Many expressed a lack of excitement about the introduction of antiretroviral therapy, and little change in their attitudes concerning the epidemic.

Abstract: This article explores the significance of an important event, namely, the Pioneers of Participation workshop held in November 2009 in Cape Town, for public participation advocacy in South Africa. By tracing the shifting consciousness of one participant, a key provincial official (Jackie O whose name has been changed), the article shows both how such events can change mindsets to create better informed, better inspired and more connected advocates for public participation, and that this transformation is not necessarily permanent. Hence, it is argued that events like the Pioneers workshop are best located in a broader advocacy strategy appropriate to the particular context of state-society relations. In South Africa’s case it is argued that this strategy ought to focus on the twin objectives of policy reform – both to make formal participatory spaces more inclusive, democratic and empowered and to support the emergence of independent, popularly rooted yet technically competent civil society formations that are capable of mediating both popular needs and the policy system. How these objectives ought to be realised is an open question, but it is clear that events like the Pioneers workshop can be a galvanising and mindset changing resource in this broader strategy.

Abstract: The road to acquiring statutory status for the Library and Information Services (LIS) sector in South Africa has been traversed numerous times over the last sixty to seventy years. In more recent years, there has been renewed vigour to explore the acquisition of statutory status for the sector in South Africa. As part of this process of acquiring statutory status, a number of studies have been conducted. This paper examines the latest drive by the Library and Information Association of South Africa (LIASA) to solicit the views of a cross section of LIS personnel with regard to the sector acquiring statutory status. This issue of the acquisition of statutory status is earmarked as a priority in the recently developed Strategic Directions 2010-2014 document of LIASA. At the 2009 LIASA Conference, a clear mandate was given for a national survey to be conducted to solicit the views of personnel that work in the LIS sector with regard to the said issue. The authors administered a short questionnaire to a sample population representing all categories of staff irrespective of whether they belonged to an association or not. The questionnaire was administered using Survey Monkey. This paper reports the results of that survey. Given the overwhelming support for the acquisition of statutory status, the authors examined significant elements that would need to be crafted into the governance structures of a statutory body for the sector.

Abstract: Obesity and associated non-communicable diseases such as Type 2 diabetes, hypertension, and ischaemic heart disease were previously thought to be diseases of affluent countries, but they are becoming increasingly prevalent in developing nations. Accessibility to cheap unhealthy food, global trade and market development influence nutrition transition towards diets with high fat and sugar contents. A decrease in physical activity due to urbanisation and other environmental factors such as crime and violence are thought to lead to an increased risk of obesity. Positive beliefs about body weight among black African women, together with the idea of association of thinness with HIV/AIDS virus infection are believed to fuel the obesity epidemic amongst this population This paper describes some of the contributory factors which black South African women are faced with in making choices about healthy living. A multisectoral approach will be needed to fight the epidemic of obesity and associated diseases. URI: http://hdl.handle.net/10566/243 Files in this item: 1

Abstract: OBJECTIVES: To review data on the prevalence, causes and health consequences of obesity in South Africa and propose interventions to prevent and treat obesity and related outcomes. METHODS: Data from existing literature were reviewed with an emphasis on changing eating and activity patterns, cultural factors, perceptions and beliefs, urbanisation and globalisation. Results of studies on the health consequences of obesity in South Africans are also reviewed. RESULTS: Shifts in dietary intakes and activity patterns to higher fat intakes and lower physical activity are contributing to a higher prevalence of obesity. Few overweight black women view themselves as overweight, and some associate thinness with HIV/AIDS. Glucose and lipid toxicity, associated with insulin resistance, play roles in the pathogenesis of the co-morbid diseases of obesity. Elevated free fatty acids in the black population predispose obese black patients to type 2 diabetes. CONCLUSION & RECOMMENDATIONS: Obesity prevention and treatment should be based on education, behaviour change, political support, intersectoral collaboration and community participation, local actions, wide inclusion of the population, adequately resourced programmes, infiltration of existing initiatives, evidence-based planning, and proper monitoring and evaluation. Interventions should have the following components: reasonable weight goals, healthful eating, physical activity and behavioural change. Genes and mutations affecting susceptibility to the development of co-morbidities of obesity and vulnerable periods of life for the development of obesity should be prioritised. Prevention should be managed in community services, identification of high-risk patients in primary healthcare services and treatment of co-morbid diseases in hospital services.

Abstract: To ascertain the anthropometric profile and determinants of obesity in South Africans who participated in the Demographic and Health Survey in 1998. RESEARCH METHODS AND PROCEDURES: A sample of 13,089 men and women (age, _15 years) were randomly selected and then stratified by province and urban and nonurban areas. Height, weight, mid-upper arm circumference, and waist and hip circumference were measured. Body mass index (BMI) was used as an indicator of obesity, and the waist/hip ratio (WHR) was used as an indicator of abdominal obesity. Multivariate regression identified sociodemographic predictors of BMI and waist circumference in the data. RESULTS: Mean BMI values for men and women were 22.9 kg/m2 and 27.1 kg/m2, respectively. For men, 29.2% were overweight or obese (_25 kg/m2) and 9.2% had abdominal obesity (WHR _1.0), whereas 56.6% of women were overweight or obese and 42% had abdominal obesity (WHR _0.85). Underweight (BMI _18.5 kg/m2) was found in 12.2% of men and 5.6% of women. For men, 19% of the variation of BMI and 34% of the variation in waist circumference could be explained by age, level of education, population group, and area of residence. For women, these variables explained 16% of the variation of BMI and 24% of the variation in waist circumference. Obesity increased with age, and higher levels of obesity were found in urban African women. DISCUSSION: Overnutrition is prevalent among adult South Africans, particularly women. Determinants of overnutrition include age, level of education, ethnicity, and area of residence. URI: http://hdl.handle.net/10566/291 Files in this item: 1

Abstract: A total of 24 species of euphausiid was collected during a survey along the South African south coast during January 1992. Communities over the Agulhas Bank were of low diversity and abundance and were dominated by Nycliphanes capensis. Those at the shelf-edge were of high diversity and abundance and were dominated by Euphausia recurI'll and Thysalloessa gregaria. Such high diversity may be maintained by vertical scgregation at night. Few species displayed obvious diel vertical migration, although N. capen sis may be able to maintain itself on the shelf by means of this behaviour. E. recurl'Cl appeared to feed on phytoplankton throughout the water column at night, reflecting the distribution of food. URI: http://hdl.handle.net/10566/374 Files in this item: 1

Abstract: The vertical distribution, abundance and size composition of a population of Pleurobrachia pileus was studied during a six-day drogue study conducted off the west coast of South Africa in February 1995. The population was centred in deep water, possibly because of the presence of a potential predator, Beroe sp., at shallower depths. The population of P. pileus failed to display clear patterns of migration, although nocturnal recruitment from deeper water resulted in a deepening of the depth of occupation then. The population was dominated by individuals <4 mm polar diameter, and large animals were confined to the upper water layers. These results are discussed with reference to possible spawning activities. Using published equations relating size to clearance rates, it was estimated that the population could remove up to 27% of integrated mesozooplankton standing stocks, and in excess of 100% (293%) at some depths.
