  • Description: The article provides a critical analysis of Marxist work on the South African state. It first examines the early Poulantzian‐State Derivationist debate on the relation between state and society, and then discusses the ‘new directions’ which focus on the state itself. The sensitivity of the ‘new directions’ to the traditional Weberian concern about state bureaucracy is important for enriching Marxist theory. But the article concludes by suggesting that a comprehensive dialectical Marxist approach to the South African state still awaits development.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 38 , Recent collecting in the Malawi lakes Chilwa and Chiuta has revealed a new haplochromine cichlid fish, Astatotilapia tweddlei, which is described and illustrated. It is distinguished from most members of this genus by an elongate, rounded caudal fin. Although having a distinctly different colour pattern and more slender pharyngeal bone, it shows a greater similarity to A. paludinosa, known only from the Malagarasi Swamp 1200 km to the north in the Zaire ichthyofaunal province, than it does to members of this genus from the closely adjacent Zambezi province from which this wetland system, in the East Coast province is separated by only some 50 km.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 37 , Paragaleus leucolomatus sp.n. is described from a pregnant female shark 957 mm total length collected off Kosi Bay, Natal, South Africa. This represents the first Paragaleus and the second hemigaleid species recorded from South African waters. P. leucolomatus differs from its congeners by its broad snout, long mouth, lower anterior teeth mostly erect-cusped and without distal cusplets, 180 total vertebrae, and coloration. The species has conspicuous white-edged fins, a black apical spot on its second dorsal, and dusky blotches on the underside of its snout. P. leucolomatus may be conspecific with a Madagascar Paragaleus erroneously assigned to the West African P. pectoralis. Diagnoses of the Family Hemigaleidae and the Genus Paragaleus are presented, as well as diagnostic keys to hemigaleids of the western Indian Ocean and to Paragaleus species.

  • Description: Experienced male marathon runners, 9 black and 10 white, with marathon times of 2 hours 45 minutes or faster, acted as subjects for the study, the purpose of which was to determine whether black runners are better suited to marathon running than whites. Body composition was determined by anthropometry. Maximal oxygen uptake (VO₂ max) and other physiological variables were measured during a continuous, speed-incremented treadmill protocol using a computer-aided data acquisition system. Subjects also ran a simulated marathon at 92.5% of the running speed at which the ventilatory threshold (VT) occurred. Physiological, gait and RPE variables were measured at 10 minute intervals during the marathon. Major findings are detailed below:- The VO₂, max averaged 60.4 ∓ 6.5 and 63.2 ∓ 2.9 mI. kg⁻¹.min⁻¹ in the black and white runners respectively and was highly correlated with best marathon race time (r = 0.86 and 0.85 respectively) and VT (r = 0.84 and 0.60 respectively) (p < 0.05). No significant differences existed between the groups in submaximal oxygen uptake (VO₂,) or % VO₂ max utilised at 16 km.hr⁻¹, but the estimated % VO₂ max utilised during a marathon race was higher in the black (89.0 ∓ 5.5%) than the white runners (81. 5 ∓ 3.1%) {p .( 0.05). The % VO₂ max utilised at 16 km.hr⁻¹ (84.8 ∓ 9.1 and 78.6 ∓ 5.8% in the black and white runners respectively) was significantly correlated with the % VO₂, max utilised while racing in the white (81.5 ∓ 3.1%) (r = 0.70) (p < 0.05), but not the black runners (89.0 ∓ 5.5%). The VT occurred at 82.7 ∓ 7.7 and 75.6 :∓ 6.2% VO₂; max in the black and white groups respectively (p < 0.05). Post-marathon blood lactic acid levels were lower in the black (1.30 ∓ 0.26 mmo1.l⁻¹) than the white runners (1.59 ∓ 0.20 mmol.l⁻¹). The respiratory exchange ratio (R) was higher in the blacks than whites when running at 16 km.hr ⁻¹ (1.03 ∓ 0.07 and 0.98 ∓ 0.03 respectively) and during the marathon (p < 0.05). There was no significant difference in pulmonary minute ventilation (Vı) between the groups, but breathing frequency (f) was higher in the black (59 ∓ 12 breaths.min⁻¹) than the white runners (45 ∓ 8 breaths. min⁻¹ ) and tidal volume (V⊤) lower in the black ( 1.33 ∓ 0.16 l.breath⁻¹) than the white runners (1.75 ∓ 0.36 I.breath⁻¹) during submaximal running at 16 km. hr⁻¹ (p < 0.05). The same trend was observed during the marathon run. During the time-course of the marathon f increased and V⊤ decreased In both groups (p < 0.05). Stroke volume decreased and heart rate increased In both groups during the time-course of the marathon (p< 0.05). Cardiac output was therefore maintained. Thermal responses were similar in the two groups. A significant increase in rectal temperature coincided with a decrease in skin temperature and may have been related to an increase in f (r = 0.86 and 0.67 in the blacks and whites respectively), H/R (r = 0.70 and 0.67 respectively) and "local" (leg) RPE (r = 0.84 and 0.82 respectively). It was concluded that black runners were able to run marathon races at a higher % VO₂ more than whites due to the blacks having lower blood lactic acid levels when running at a similar % VO₂ max. Given similar maximal oxygen uptakes, this would enable blacks to run faster. Cardiopulmonary adjustments occur during the time-course of a marathon which maintains Q and Vı

  • Description: While the terrestrial ecosystem of the Prince Edward Island Group has been subject to intensive research, the marine ecosystem has to a large extent been neglected. This together with the possible existence of an "island effect" at these islands, as was first proposed after the visit to these islands of the French vessel Marion Dufresne, led to the initiation of a programme to determine the distribution of standing stocks and the productivity of phytoplankton and zooplankton in the neritic seas of these islands. To do this and before a detailed biological survey could be attempted, it was first necessary to define the physical and chemical properties of the circuminsular waters. This dissertation discusses the results of several surveys to these islands in the light of a possible "island effect" and comments upon processes likely to influence such an effect

  • Description: From Preface: The study focusses on spatial aspects of farming and particularly how di stance from marketing centres influences farming activity. However, not all aspects of farming activity could be given close attention due to the limited time and funds available and it was decided to isolate two aspects of farming activity for detailed study, namely, farm size and intensity. Other variables, such as land-use, are looked at in relation to the two main variables. Although East Griqualand is the general area selected for study, for practical purposes it was decided to select areas within East Griqualand for an in-depth study. As the study focusses on the influence of distance from marketing centres on farming activity, it was decided to select marketing centres in East Griqualand around which farming takes place. There are six of these centres in East Griqualand, that is, Kokstad, Matatiele, Cedarville, Franklin, Swartberg and New Amalfi. Two marketing centres, Cedarville and Swartberg, were selected and the farms served by these centres became the two sub-areas in which the research was conducted. The selection of the marketing centres and the justification for this selection is discussed in Chapter Four. A problem arose when calculating the distance from the farming unit to the marketing centre where a single set of books is kept even though the farming unit does not consist of one contiguous area. It was, however, found that all farmers conduct farming operations from a central farm, usually that on which they reside and on which farming implements and other farming requirements are stored. The distance was therefore calculated from the farm gate of the farm from which farming operations are controlled. The general study area is show in Figure 6. However, it was difficult to delimit the exact study area on the map as many of the farm boundaries were imperfectly known by farmers and were considered confidential information by local agricultural officials. The two sub-areas consist of the areas surrounding the marketing centres of Cedarville and Swartberg respectively. As a study of this nature has not previously been conducted in East Griqualand, it was decided that the study should constitute a pilot survey. As such, the study is a preliminary survey aimed at identifying general trends of the relationship between distance to marketing centres, farm size and intensity of fanning in the selected areas. The study could therefore be used to provide pointers for further research and act as a basis for a more comprehensive study of the same nature in East Griqualand.

A geographical analysis of nutrition in the Eastern Cape and Ciskei

  • Identifier: vital:4812 , http://hdl.handle.net/10962/d1004905
  • Description: From preface: The primary aim of the thesis is to make an anthropometric assessment of levels of nutrition of black pre-school children in selected communities of the Eastern Cape and Ciskei. The communities are those of black labourers and their families on white-owned commercial farms in the Dias Divisional Council area of the Eastern Cape; a rural community of an area of Ciskei known as the Amatola Basin; and Tsweletsl'lele, a 'closer settlement' or resettlement area in Ciskei. A pilot survey of school entrants in the Albany magisterial district also sheds light on the nutrition of children in the small towns, such as Grahamstown, of the Eastern Cape. Through an analysis of nutritional conditions in these disparate communities, it should be possible to begin to establish the geographical variation of nutrition in the region. Black communities in the metropolitan area of Port Elizabeth are not considered in the thesis, but on-going surveillance in the city, by the author, will elucidate nutritional conditions there. In achieving the primary aim of the thesis, attention will be focussed on inter-community rather than intra-community variation in nutrition. Nutrition may vary within communities (intra-community variation), for example, within different parts of the Dias Divisional Council area. While such variation is 1 ikely to be minimal, as will be discussed in the presentation of results in chapter 6, section A(l), it is in itself important, and present research endeavours within the surveillance programme are being geared to explore this dimension of nutritional variation more fully. Inter-community variation in nutrition provides, however, a more than sufficient focus for the thesis. A secondary aim of the thesis is to explore the relationship between nutritional status and socio-economic conditions prevailing in the surveyed communities. The secondary aim makes it possible to obtain a better understanding of the processes whi ch infl uence the geographical pattern of nutrition. A consideration of socio-economic conditions, both within the communities and within the Eastern Cape and Ciskei as a whole, also provides a context in which the nutrition results can be assessed. The third aim of the thesis is to assess possible applications of the survey results to policy formulation, thereby providing an applied dimension to the work.

A historico-theological study of Pentecostalism as a phenomenon within a South African community

  • Description: Preface: An attempt is made in this thesis to document the history of Pentecostalism among Indians in South Africa and to study and evaluate its religious character and main theological tenets. Obviously the peculiar socio-political situation of the Indians in South Africa has influenced the character of Indian Pentecostalism, which has in turn been able to address itself to the critical, cultural and religious disjunctions within this community. Hence an investigation of the dynamic tensions that obtain between crises in the Indian community and Pentecostalism will not only clarify the course of its history but will also explain its theological emphases. However, several studies on Pentecostalism in other communities have concentrated on the sociological dimension almost exclusively and many have even concluded that Pentecostalism is the spontaneous result of psychosocial; economic or cultural upheavals . This kind of reductionism has been largely the result of the uncritical use of 'functional-type' theories postulated by sociologists of religion. Indian Pentecostalism, while it has to be examined within the complex context of the South African community, cannot as we shall show, be adequately explained by any of the prevailing 'functional-type' theories because these theories reduce religion to a sociological function. Since the functional theory has the effect of limiting the perspective on religion to such an extent that the basis of religion, that is, the relation between the individual and faith, is either belittled or ignored, it has been jettisoned in this thesis for an approach free of any deliberately formulated 'theoretical framework'. However, it is necessary to critically examine some of the more popular 'functional-type' theories and the way they have been applied to the study of the Pentecostal movement here and elsewhere, so that by exposing the shortcomings of their application and the contradictions inherent in their assumptions, the approach adopted in this thesis could be clarified.

  • Description: The Uitenhage artesian aquifer north-west of Port Elizabeth in South Africa, is one of the few artesian groundwater systems in Southern Africa. The Uitenhage - Coega, and Kruis River areas, are the most important portions of the Uitenhage Artesian System in terms of water abstraction and water use. This study concentrates on the Uitenhage - Coega area and in particular, on the Coega Ridge where the Table Mountain Sandstone (TNS) aquifer occurs at relatively shallow depths. The investigation is aimed at assessing the geological, hydrogeological and hydrochemical characteristics of the HIS and any other aquifers present, with the object of providing quantitative data for use in future decisions on the water resource management of the area. In order to achieve these objectives, field work, involving a hydrocensus, geological mapping, geophysical exploration, drilling, aquifer testing and hydrochemical sampling was carried out. Analysis of these data provided information on the extent of the aquifers, their hydrogeological characteristics and the chemical nature of the various groundwater types.

  • Description: Lee, T. et al (1981) proposed the encapsulation of hormones such as progesterone into serum albumin beads, such that their in vivo proteolysis would allow a gradual release of hormone at low levels, for extended hormone action. It was proposed, in the Department of Microbiology, Rhodes University, to replace the hormone component of the above bead formulation, with virus as antigen, in the development of a vaccine. Beads optimally crosslinked at 1% final glutaraldehyde concentration, containing Nodamura virus, were shown to promote an adjuvant effect in vivo, analogous to the release of antigen from Freund's Complete Adjuvant (FCA), so that extended immunostimulation resulted. It was shown that soluble antigen promoted a short-lived primary immune response, peaking around day 25 following inoculation. Antigen presented in beads, on the other hand, initially elicited a low humoral response, but this response gradually increased up to a peak around day 110 post inoculation, before decreasing. No apparent adverse side-effects were noted following inoculation of antigen-containing serum albumin beads, compared to necrosis following antigen in FCA inoculation, supporting the proposal of using albumin homotypic for the test inoculee animal, so that the beads would themselves be non-immunogenic and would merely act as a vehicle in the vaccine formulation. The indirect enzyme-linked immunosorbent assay (ELISA) was used to monitor the humoral response to antigen following inoculation. Results showed that covalent crosslinking of albumin in the formation of the beads did not promote immunogenicity on the part of the chemically altered albumin. The ELISA test was used to indicate the kinetics of the IgG response to Nodamura virus when presented in formulations such as: Freely soluble virus or its subunit; soluble intact virus inactivated by treatment with glutaraldehyde; intact virus entrapped in serum albumin beads cross; linked at different percentage final glutaraldehyde concentrations and also virus subunit prepared in albumin beads. The presence of virus-neutral ising antibodies was noted in serum obtained from rabbits inoculated with virus entrapped in albumin beads. Virus infectivity, titrated in mice, showed protection against virus challenge after incubation of virus with serum obtained above.

A total of 19 species of these two genera occur in the Indian Ocean west of the southern tip of India: Neoniphon argenteus, N. aurolineatus (Flammeo scythrops Jordan & Evermann and Holocentrus anjouanae Fourmanoir are junior synonyms), N. opercularis, N. aurolineatus, Sargocentron caudimaculatum, S. diadema, S. ittodai (first records for the Red Sea and western Indian Ocean), S. macrosquamis (recently described from the Red Sea and Amirante Group, Seychelles, the range here extended to Kenya, Mozambique, Mauritius, and the Chagos Archipelago), S. melanospilos (usually misidentified as cornutum which is known only from the Indo-Malayan region), S. microstoma (known in the region only from Maldive Islands and Astove Island), S. praslin (usually not distinguished by authors from S. rubrum; Holocentrum marginatum Cuvier is a synonym), S. punctatissimum (has priority over lacteoguttatum due to selection by first revisor, Bleeker, 1873), S. rubrum, S. seychellense (an insular western Indian Ocean species), S. spiniferum (Holocentrum melanotopte- rus Bleeker is a junior synonym), S. tiere (Holocentrum elongatum Steindachner is a junior synonym), S. tiereoides (a new western Indian Ocean record), S. violaceum, and a new species, S. inaequalis (closely allied to macrosquamis Go- lani, 1984, differing in variable Spination of preopercle, modally one fewer pectoral ray, fewer average number of lateral-line scales and a more elongate body). S. inaequalis is described from a total of 7 specimens from the Chagos Archipelago, Seychelles and Comoro Islands. S. melanospilos is recorded for the first time from the Red Sea where it appears to be subspecifically distinct from populations elsewhere in the Indo-Pacific region (no subspecific name proposed). Holocentrum macropus Gunther, allegedly collected at Mauritius, is a misidentification of the Atlantic Holocentrus ascensionis (Osbeck). A lectotype is selected for S. microstoma. Neotypes are designated for S. praslin and S. rubrum. Colour photographs of fresh specimens of all of the species except S. macrosquamis are presented. , Rhodes University Libraries (Digitisation)

  • Description: A stability-indicating high-performance liquid chromatographic method with on-line clean-up has been developed for the analysis of betamethasone 17-valerate in topical dosage forms. A short pre-column containing 10 μm octadecylsilane mounted into the sample loop position of an injection valve was used as the primary clean-up step. The utilization of a diode-array UV detector allowed the quantitative analysis of betamethasone 17-valerate together with its degradation product, betamethasone 21-valerate, as well as the qualitative analysis of these compounds, relevant internal standards and the preservatives chlorocresol and methyl hydroxybenzoate contained in the cream and lotion formulations, respectively. Typically, cream and lotion dosage forms were dissolved in acetonitrile and ointments in tetrahydrofuran, internal standards added and aliquots injected onto the analytical system. Dosage form excipients were retained on the loop column and back-flushed to waste with the aid of a second solvent pump while components of interest were allowed to transfer to the analytical column for quantitative analysis. The method is accurate, precise and stability indicating and permits the rapid on-line analysis of betamethasone 17-valerate from complex topical formulation matrices without prior extractions.

  • Description: Chicory (Cichorium intybus L) is a deep rooted biennial (or weakly perennial) composite that is grown as an annual in South Africa for its parsnip-like root. In its wild state the plant is a perennial with thin fibrous roots, but, through selection and propagation, cultivars with large, fleshy roots have been developed. From a purely horticultural standpoint, chicory is of interest as a pot-herb, a salad plant and as a root (Bailey, 1942) . As a root, the chicory plant represents an important article of commerce. In South Africa, the plants are grown virtually exclusively for their roots which, after drying, roasting and grinding, are used as an additive to, or substitute for, coffee (Introduction p. 11)

Tryptic peptide mapping of ¹²⁵I-labelled group antigen by ion exchange chromatography was used to assess the structural relatedness of seven BTV serotypes from Southern Africa, North America and Australia. Each serotype had several tyrosine containing tryptic peptides which were unique, but approximately 35% of the peptides analyzed were found to be highly conserved between all 7 serotypes. BTV-20 appeared to be closely related to BTV-B and these two serotypes with BTV-4 and BTV-17 appeared to form a closely knit central cluster. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

  • Description: From Preface: A reader looking to this study for a charting of the diverse religious views held by Tennyson at different periods in his life may be disappointed. My primary concern has been not with religious forms, but with the numinous impulse. However, though I approached the topic with a completely open mind, I find my own Christian convictions have been strengthened through the study of Tennyson's poetry. As the title indicates, I have not attempted to deal with the plays. To explore both the poetry and the plays in a study of this length would have been impossible. I have perhaps been somewhat unorthodox in attempting to combine several disciplines, especially since I cannot claim to be a specialist in the areas concerned. However, I felt it necessary to approach the subject from a number of points of view, and to see to what extent the results could be said to converge on some sort of central "truth". When I have despaired of being able to do justice to a particular aspect within the imposed limits, I have sometimes found comfort in the words of Alan Sinfield (The Language of Tennyson's "In Memoriam", p.211): "We can only endeavour continually to approach a little closer to the central mystery; the ma j or advances will be infrequent, but most attempts should furnish one or two hints which others will develop.
