  • Description: A developmental paradigm was adopted as a theoretical base from which the effectiveness of the Natal Education Department Career Education lesson-guide in promoting career maturity amongst high school pupils was investigated. It was argued that careers education embodies a distinctive approach to careers work. This approach is described. South African Careers Guidance practices are evaluated in terms of fit, and are compared to American and British ones. To investigate the outcomes of the NED lesson guide, 160 predominantly white, male and female pupils in Standards 6 - 10 were randanly divided into control and experimental grotps and underwent a six session classroom based careers education programme. In addition to the NED material,alternative materials (CRIC - Std. 7 and CRAC - Std. 9) were used on a second experimental group in two standards. The Career Maturity Inventory Attitude Scale was used to measure the outcomes. Analysis of variance and t-tests for the difference between means were used to analyse the data. The results were significant only in Standard 8. For all the other standards with all the materials, they were insignificant. Reasons for and implications of these findings are discussed.

  • Description: Towards the end of 1984 the Development Studies Unit (DSU) in the Institute of Social and Economic Research (ISER) at Rhodes University identified a need to undertake an investigation into the status of overall physical and socio-economic planning and development in Grahamstown. The initial intention of such an investigation was to identify, analyse and assess existing research related to the development of Grahamstown in order to provide a benchmark that could reduce the incidence of duplication and overlap in future research projects and to provide a point of departure for the design of more specific and action-oriented research and the formulation of feasible strategies for future development in the City. During the course of comprehensive background investigation and discussions with a wide range of local interest groups, it became clear that the proposed review of issues related to planning and development in Grahamstown would be far more extensive than originally anticipated. In addition, 1985 turned out to be an eventful year and the DSU actively encouraged research by other agencies and individuals into related issues which were deemed to be an integral part of the proposed review. For these reasons, it was decided to publish the preliminary research results in a series of Development Studies Working Papers to provide a focus of attention for particular aspects of the work. This was felt to be in accordance with the intent of the ISER Development Studies Working Paper Series which is to publish the basic results of research undertaken in order to facilitate and encourage its further development into more substantial publications. This has resulted in a series of Working Papers to be published under the general title of "A Review of Issues Related to Planning and Development in Grahamstown". This Working Paper is the fourth in the series and consists of an annotated bibliography of publications dealing with the process of planning and development in Grahamstown. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

  • Description: A simple, sensitive and reliable high-performance liquid chromatographic procedure has been developed for the determination of erythromycin in human serum and urine using amperometric detection. A solid-phase extraction procedure was used followed by chromatography on a reverse-phase column. The mean recovery of erythromycin from serum and urine was 80%. This method allows both erythromycin and its principle degradation product, anhydroeythromycin, to be determined during a period of sample storage at 4 degree C and minus 15 degree C. The method is sufficiently sensitive and precise and is thus highly suited for use in both pharmacokinetic and stability studies.

  • Description: From Introduction: Bacterial cells all have a cytoplasmic membrane (see Figure 1) which regulates the movement of ions and molecules into and out of the bacterium. Enclosing this membrane is a cell wall of which there are two general types, which are differentiated by the Gram stain(02) as being either gram positive or gram negative (depending upon whether they hold the gram stain after washing with ethanol). The cell wall provides the cell with shape and rigidity and is composed, in the case of gram positive types, of peptidoglycan, and in the case of gram negative bacteria, of a peptidoglycan and an outer membrane (see Figure 2). The peptidoglycan layer, common to both cell wall types, consists of a backbone of alternating units of N-acetylglucosamine and N-acetylmuramic acid to which peptides are attached by amide links. This heteropolymer is a highly cross linked mosaic and this gives it strength and rigidity. In gram positive bacteria, this layer also contains two carbohydr ate antigens, a simple polysaccharide and a teichoic acid; these are usually the type specific or major group antigens of the bacterium. Many of the bacteria also produce exopolysaccharides (see Figure 3) either as discrete capsules (for example, the Enterobacteriaceae K antigens) or unattached slime layers (for example, the Enterobacteriaceae M antigens). The vast majority of these polysaccharides are heteroglycans(03) composed of contiguous oligosaccharide repeating units. Their monosaccharide components are largely neutral hexoses, 6-deoxy hexoses and also amino sugars. (03) Pentose units are rare. (03) The capsular polysaccharides usually have a high content of acidic constituents such as uronic acids, phosphate groups, or pyruvate ketals.

  • Description: A measure of four types and five contexts of alienation, as well as ten personality traits, was obtained via the ·application of the Alienation Test and Howarth's Personality Questionnaire. The sample (~= 195) comprised of both high school pupils and adults drawn from the local population of English and Afrikaans speaking Whites and "Coloureds" from a town in the Eastern Cape of South Africa. These six sample groups allowed for comparisons on the measures for factors such as race, age and cultural differences. The literature review showed repeated reference to the "alienation" of the "Coloured" people of South Africa in the political, social and cultural spheres. However, the research in this area has been sparse. The main object of the study, therefore, was to determine if "Coloureds" do feel alienated, as well as the contexts of this alienation, using Whites as a comparative group. possible differences in personality traits between "Coloureds" and Whites have been associated with the differences in behaviour exhibited by these two groups, but past research has failed to find many differences. The second objective of this study, therefore, was to determine if there are differences between the personality traits of "Coloureds" and Whites, and to extend the past research. Researchers have shown that there is a relationship between alienation and personality traits, but have not adequately addressed the nature of this relationship or its implications. Following from this, the third objective of the study was to examine the relationship between alienation and personality traits, as well as their ability to predict alienation. Results on the Alienation Test showed that "Coloureds" do differ significantly from Whites and exhibit far higher levels of alienation. These differences are most marked on those types and contexts of alienation reflecting a distance from the social and political environment. Results on the personality measure showed minimal differences in personality traits between the groups. Where they were evident, they could be attributed to environmental factors. Lastly, there was a relationship between alienation and certain personality traits, but these traits had limited power to predict alienation. Taking all findings of the study into account, it is evident that the social environment, and specifically a discriminatory social environment, affects feelings of alienation to a far greater extent than personality traits. In addition, the large differences in scores of the "Coloured" and White groups on the measure of alienation and the minimal differences on the measure of personality, provides evidence that what is measured by alienation and what is measured by personality traits, are two distinctly different constructs.

A study of the nature, function and availability of orders of restitutio in integrum and specific performance as remedies in South African law

  • Description: This study is of two remedies that are available in South African law: orders of restitutio in integrum, and specific performance. The study demonstrates that, by treating these remedies as legal topics in their own right, a greater understanding emerges of their inherent characteristics, the role that they play in the law, and of the particular circumstances in which these remedies are available. An order of restitutio in integrum performs an important and unique function in South African law. The fundamental realisation is that it is a remedy in terms of which the courts exercise an extraordinary and discretionary power, and nullify ab initio legal transactions, or the legal consequences of events, which were previously perfectly valid and enforceable at law. Because of the extraordinary nature of this remedy, the circumstances in which it is available are limited by the requirement that iusta causa must exist to justify nullification. Further, before the remedy is available, the person seeking relief must have suffered loss or prejudice as a result of the event complained of. Finally, a mutual restoration of benefits received by the persons involved is required. The nature and effect of orders of restitutio in integrum, and the essential elements which determine the availability of the remedy, enable it to be distinguished from, and contrasted with, other remedies in South African law. An order of specific performance is available in South African law, at the option of a plaintiff, to enforce the actual performance of contractual undertakings. The remedy is appropriate to enforce positive undertakings, as well as acts of restraint. For the remedy to be available, it is firstly necessary that a contractual obligation be proved to exist. Secondly, performance of that obligation must be due. Thirdly, the performance sought must not in fact have already been rendered. These elements determine the availability of the remedy in particular factual circumstances, such as in cases involving pre-emptive rights. The nature and characteristics of the remedy are determined by principles of South African, and not English law. The remedy is available as of right in South African law, but subject to a discretionary power of a court to refuse to order specific performance. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

A study of the population dynamics, production and potential yield of the sardine Limnothrissa Miodon (Boulenger) in Lake Kariba

  • Description: The limnology of Lake Kariba, especially those aspects that affect sardine biology, are described. The hydrological regime of the lake is seen as a major influence and may be one of the reasons why the fish are very much smaller in Kariba than they are in Lakes Tanganyika or Kivu. Growth was reassessed and there appeared to be a correlation between rates of growth and limnological parameters. In particular, the fish appeared to grow faster, but smaller, in the man-made lakes and this may be a consequence of food shortages brought about by their hydrological characteristics. Mortality rates were also much higher in Kariba and this tended to support the view that the lake is a relatively unsuitable habitat for the sardines. However, estimates of biomass, expressed in terms of lake volume, contradicted this as they were very similar in both Kariba and Tanganyika. The life history strategy of Limnothrissa in Kariba was therefore to reduce its size and increase its productivity in order to maintain the maximum possible biomass and its very high P/B̄ ratio was probably the means by which this was achieved. In terms of lake volume the predicted yields from the pelagic communities of Kariba and Tanganyika were very similar, equivalent to about 20 000 t annually for Kariba. This is close to the yield predicted by several empirical models and the fishery now appears to be entering a phase where increases in effort will not be matched by increased yields. The mechanisms for controlling effort in the fishery appear to be inadequate and particular concern was expressed about the lack of co-ordination between the Zimbabwean and Zambian fishery authorities in planning the development of this shared resource.

  • Description: Programmes designed for the pre-service education of secondary school geography teachers reflect the assumptions held by programme designers regarding the nature of education, teaching in general and geography teaching in particular. The general practice is that in universities, individual method lecturers design their programmes and in colleges within a department of education the programmes are centrally planned. Each programme focuses on a specific context. This, together with the autonomy enjoyed by university method lecturers in designing their courses, has resulted in the variations found in geography teacher education programmes. The evidence of this is found in the structure and duration of courses, the course content, the strategies used to educate teachers and the way in which the course is evaluated. This thesis is an attempt to establish consensus and divergence in pre-service education programmes for secondary school geography teachers regarding their organisation, specific knowledge imparted to student teachers; skills, values and attitudes developed. The pre-service education of secondary school geography teachers in South Africa is revealed in an analysis of views held by method lecturers, practising teachers in secondary schools, and student teachers and an analysis of course outlines , teaching practice assessment forms and geography method examination papers. Conclusions are drawn and recommendations made for improving the initial education of secondary school geography teachers in Transkei

  • Description: Quantitative community descriptions, based on point quarter sample data, are made for a number of dune forest units along the East London coast. These are supported by multivariate classifications and ordinations which illustrate the inter community variation between the sampled seaward, landward and dune valley sites. Climax valley forest is floristically most characteristic and can be clearly distinguished from the seaward and landward thicket communities which tend to show a degree of similarity. Within-forest community differences are shown to be more significant than variation along the coast. This appears to indicate that climoedaphic gradients established laterally to the coast induce a greater floristic response than the rainfall gradient within the study area. The state of developnent within the dune soil profile and the rate and effect of salt spray deposition are considered to be important factors influencing dune forest succession and are discussed in some detail. An overview of certain other climatic variables as well as the geological features within the study area is also given. A phenology study of the dune forest, scrub-thicket and strand plant cornnunities shows some general patterns of flowering and fruiting phenorhythms. Although much variation was observed, there appears to be a bimodal hyperactive phenophase response which is thought to be related to rainfall or periods of favourable soil moisture conditions. A brief discussion of some of the positive and negative human influences on the coastline is given. This includes a description of the management activities carried out in the area as well as the demands placed on ·the coastal resource.

  • Description: The alpha taxonomy of the southern African Synodontis is reviewed, based on the analysis of 48 characters. The previously descriptive characters of barbel branching and humeral process shape are compared by various quantitative methods. The variation in colour pattern is recorded with the aid of detailed line drawings. The definitions of head length, head width and humeral process length are altered slightly from their traditional descriptions to ensure greater consistency and precision in measurement. New characters include the size of the caudal fork, the number, shape and arrangement of the premaxillary teeth, and two measurements between the cranium and pectoral girdle. Both uni- and bivariate methods are used to record and compare the intraspecific variation of each character. Principal components analysis of 19 morphometric characters is used to assess the degree of similarity of nine allopatric populations of S. zambezensis. Ten species are recognized from the study area, two of which are described as new: S. nebulosus Peters 1852, S. zambezensis Peters 1852, S. nigromaculatus Boulenger 1905, S. njassae Keilhack 1908, S. woosnami Boulenger 1911, S. macrostigma Boulenger 1911, S. leopardinus Pellegrin 1914, S. thamalakanensis Fowler 1935, S. macrostoma sp.n. and S.vanderwaali sp.n. A key to their identification is provided. Characters are discussed in terms of their contribution to the identification of the southern African species and, where possible, suggestions made concerning the value of these characters to the taxonomy of the genus as a whole. The rejection of certain characters previously used in Synodontis keys is discussed and alternatives proposed. The state of southern African Synodontis taxonomy is assessed and recommendations for future research are given
