Masters in Public Administration - MPA This research report examined the key policies of globalisation namely, privatisation and deregulation of services and also their implication on the Tri-partite alliance. Because they have impacted negatively on major economic sectors, particularly to those that help the needy. Therefore, the study explores these initiatives, which has been debatable in South Africa under the dominant understanding of ‘progress’ or ‘development’. The Objective of the study is to lay the basis for the examination and evaluation of policy option with regard to privatisation and deregulation of services in South Africa and to engage South Africa effectively in global policy debates and adjust in global trends and negotiations within the region (SADC) and other international countries. It examines global challenges and opportunities / threats for South Africa as a developing country in the emerging global order. This study also attempts to provide answers to several questions concerning privatisation and deregulation of public services in South Africa. To the poor, is deregulation and privatisation of state assets threatening to become the new apartheid, which is an instrument of exclusion, not just from a better life but even from the very basic services? How are workers and including the poorest of the poor affected by the status of deregulation and privatisation? Do the timing and specifics of these processes matter? Who should attempt to regulate the auction, as some of government officials seems to be corrupt? And which prior restructuring policies are worth implementing? South Africa
Petrographic characterization of sandstones in borehole E-BA1, Block 9, Bredasdorp Basin, Off-Shore South AfricaVan Bloemenstein, Chantell Berenice 2006 (has links)
Magister Scientiae - MSc The reservoir quality (RQ) of well E-BA1 was characterized using thin sections and core samples in a petrographic study. Well E-BA1 is situated in the Bredasdorp Basin, which forms part of the Outeniqua Basin situated in the Southern Afircan offshore region. Rifting as a result of the break up of Gondwanaland formed the Outeniqua Basin. The Bredasorp Basin is characterized by half-graben structures comprised of Upper Jurassic, Lower Cretaceous and Cenozoic rift to drift strata. The current research within the thesis has indicated that well E-BA1 is one of moderate to good quality having a gas-condensate component. South Africa
Interactions between ants, herbivorous insects and bracken (Pteridium aquilinum), a fern with extrafloral nectariesRashbrook, Vanessa Karin 1989 (has links)
Bracken (Pteridium aquilinum) is a cosmopolitan species of fern which possesses extrafloral nectaries. A survey of the arthropod fauna associated with the plant throughout its range in South Africa identified the most widespread and damaging bracken herbivores and those species most likely to be influenced by ants visiting the extrafloral nectaries. Seventeen herbivorous arthropods were found to be definitely feeding on bracken and a further thirteen species with a less certain status were recorded. In addition, several species of ants were observed on the fronds and feeding at the extrafloral nectarie. On the basis of their widespread distribution and abundance, four bracken herbivores emerged as being particularly detrimental to the plant in South Africa. They were an eriophyid gall mite, a leafhopper and two moths. The biology of the two lepidopterans, Appana cinisigna and Panotima sp., suggested that they were potentially vulnerable to ants at various stages of their life histories. Laboratory experiments were undertaken to observe ant-lepidopteran interactions under controlled conditions. The ant Crematogaster peringueyi rapidly removed exposed A. cini igna eggs, but did not appear to regard Panotima eggs as food items. Small instar larvae of both species proved vulnerable, but the larger larvae appeared capable of escaping ant predation. Ant exclusion experiments in the field, using natural and artificially augmented ant densities, were carried out at two sites near Grahamstown. The dominant ant species was C. peringueyi. Neither the numbers of lepidopterans nor levels of herbivory were significantly reduced by the presence of ants . Despite the implications of the laboratory tests, the results of these field experiments did not support the hypothesis that ants which visit bracken extrafloral nectaries benefit the plant. Ant-bracken field studies on other continents also reported no significant ant-related effects, though marginal reductions in the abundance of certain herbivores have been noted at one site in the U.K. Since ant protection does not appear to be an inevitable consequence of having extrafloral nectaries, their value to bracken is in some doubt. The most likely situation where effective protection will occur is when high densities of vulnerable herbivores are preyed upon by large numbers of aggressive ants. However, even under these conditions, enhancement of plant fitness is not inevitable. This raises the question of why extrafloral nectaries have been retained in a plant that is as successful and widespread as bracken.
Strike comparison of the compositional variations of the lower group and middle group chromitite seams of the critical zone, Western Bushveld complexDoig, Heather Leslie 2000 (has links)
The variations in the composition, specifically the Cr20 S content and the Cr:Fe ratio, and the morphology of the Lower Group (LG) and Middle Group (MG) chromitite seams of the Critical Zone (CZ) across the western Bushveld Complex, including the Ruighoek and Brits sections, is investigated by means of whole-rock chemical data, both major and trace elements analysis, XRD and electron microprobe data. As a result ofthe paucity of exposed or developed LG1 - LG5 chromitite seams in the western Bushveld Complex, this study is confined to the investigation of the compositional variations of the LG6 to MG4 chromitite seams. In only one section, the Ruighoek section, was the entire succession of chromitite seams, from the LG1 - MG4, exposed. The silicate host rocks from the LG6 pyroxenite footwall to the collar of the CC2 drillcore (lower uCZ) in the Rustenburg section were sampled. This study reviews the compositional trends of the silicate host rocks, as the compositional variations of the chromitite seams reflect the chemical evolution of the host cumulate environment and, to a lesser degree, the composition onhe interstitial mineral phases in the chromitite seams. The compositional variations of the LG and MG chromitite seams are attributed to the compositional contrast between the replenishing magma and the resident magma. The chemical trends of the LG and MG chromitite layers and the host cumUlate rOCKS do not support the existence of two compositionalfy dissimilar magmas in the CZ, rather the cyclic layering of the CZ and the chemical variations of the chromitite seams are attributed to the mixing of primitive magma with the resident magma, both of which have essentially similar compositions. The compositional variations of the LG and MG chromitite seams along strike away from the supposed feeder site (Union section) to the distal facies (Brits section) are attributed to the advanced compositional contrast between the resident magma and the replenishing primitive magma pulses. The CZ is characterized by reversals in fractionation trends and this is attributed to the compositional evolution of the parental magma and not to the replenishment of the resident magma by influxes of grossly dissimilar magma compositions. The Cr20 S content and the Cr:Fe ratio of the MG chromitite layers increase from the Ruighoek (near proximal) section to the Brits section (distal facies). This is attributed to the advanced compositional contrasts between the resident magma and the replenishing primitive magma. In contrast, the Cr20 3 content and Cr:Fe ratios ofthe LG6 and LG8a chromitite seams decreases eastwards from the Ruighoek section. The average Cr:Fe ratio for the western Bushveld Complex is between 1.5 and\2.0, nonetheless, a progressively lower Cr:Fe ratio is noted from the LG1 chromitite up through to the MG4 chromitite seam in the Ruighoek section. tn the LG2 - LG4 chromitite interval a deviation to higher.lratios is encountered. A progressive substitution of Cr by AT and Fe in the Cr-spinel crystal lattice characterizes the chromitite succession from the LG1 seam up through the chromitite succession to MG4. The petrogeneSiS of the chromitite seams of the CZ is attributed to magma mixing and fractional crystallization of a single magma type.
Screening of the white margined sole, Synaptura marginata (Soleidae), as a candidate for aquaculture in South AfricaThompson, Ernst Frederick 2004 (has links)
The white margined sole Synaptura marginata (Soleidae) was isolated as the most likely candidate for flatfish aquaculture in South Africa. The aim of the study was to screen the sole as a candidate aquaculture species by way of a comprehensive study of its biology and life history strategy and to identify possible "bottlenecks". The study was undertaken on the assumption that the biological data would provide valuable information for developing specific technologies that might be required for the farming of this species. Specimens were collected monthly by spearing along the Eastern Cape coast of South Africa between December 2000 and March 2002. Length-at-age data required for modeling the growth of S. marginata was obtained from sectioned otoliths. A Von Bertalanffy growth model with an absolute error structure best describes the growth for this species. The model parameters were: L∞ = 429.5 mm TL, K = 0.24 and t₀ = -1 .79 years. Analysis of gut contents showed that S. marginata feed exclusively on polychaete worms, mainly of the genus Morphysa. S. marginata shows a protracted summer spawning season of six months, from October to April. This was determined by the calculation of a monthly gonadosomatic index and a macroscopic maturity scale. Histological examination of the ovaries revealed five ovarian developmental stages. Size at 50% and 100% sexual maturity for females was calculated to be 235 mm TL and 300 mm TL (ca. 1.5 - 2.5 years of age) and all males> 154 mm TL were mature. S. marginata is a batch spawner, releasing a minimum of 3 batches of eggs per year. Relative fecundity is high (34000 eggs per year I kg) and this coupled with the protracted spawning season would make it possible to obtain adequate numbers of juveniles (for farming) for approximately five to six months of the year. Comparative analysis of the biological characteristics in relation to other soles farmed elsewhere in the world suggests that S. marginata is a suitable candidate for marine fish culture in South Africa.

LL.M. Tydens die ontwikkeling van die verskeie besigheidsondernemingsvorme in Suid-Afrika is groot aandag geskenk aan statutere regulering van hierdie ondernemingsvorme, asook interaksie tussen hierdie statutere reguleringsmaatreels en harmonisering daarvan met bestaande wetgewing wat daarop van toepassing mag wees. Dit wil egter voorkom dat statutere regulering in Suid-Afrika ten aansien van sekere ondernemingsvorme ver tekort skiet, aangesien daar geen onafhanklike wetgewing in Suid-Afrika bestaan ten aansien van byvoorbeeld vennootskappe nie, anders as in ander werelddele. Daar kan derhaiwe tereg gese word dat die vennootskapsreg beskou kan word as die "stiefkind" van die Suid-Afrikaanse reg. Alhoewel daar steeds verskeie Ieemtes en anomaliee bestaan ten aansien van statutere gereguleerde ondernemingsvorme en harmonisering van sekere statutere bepalings daarop van toepassing, met bestaande wetgewing, wil dit voorkom asof die bestaande verwysingsbronne ten aansien van die vennootskapsreg en ander wetgewing ernstige anomaliee teweegbring, wat vervolgens selektief bespreek gaan word, met spesifieke verwysing na anomaliee wat bestaan in die toepassing van sekere bepalings van die Insolvensiewet ten aansien van vennootskappe.

D.Phil. (African Languages) This study attempts to fill a gap in the available research on language use in Black urban speech communities. Previous studies conducted in these communities, concentrated on specific language varieties. However, no attempt at describing the entire language situation in such a community had hitherto been made. A macro-level sociolinguistic description which would serve as an orientation for various detailed studies on the language varieties occurring in these communities, was therefore needed. The aim of the present study was to provide such a description. In order to achieve this, a sound theoretical framework had to be established. Phenomena such as language 'Contact, language variation and language use had to be researched and defined in order to apply to the particular situation under investigation. In .this sense, this study has succeeded in making a contribution to the theoretical debate regarding various sociolinguistic concepts, in that it has shown how these concepts apply to the South African situation. The study also investigated qualitative research methodology. The background to and implications of this methodology were discussed and analysed. A particular type of qualitative research, namely, interactive qualitative research was explored. Within this framework, a unique approach to two basic data collection techniques, namely, individual and focus group interviewing, was proposed. These techniques were used to gather the primary data for this study, and were discussed in detail. The primary data was gathered from residents of the township known as Tembisa. The secondary data was taken from studies done on individual language varieties in other Black urban speech communities. The primary data was analysed and a comprehensive qualitative description of the entire language situation in the speech community of Tembisa was given. The findings of the Tembisa study were compared with the secondary data, resulting in the identification of a number of distinct language varieties which occur in the township situations that were studied. These are: a number of Standard languages, Fanakalo (although seldom used), a Black urban vernacular, Afrikaans-based Tsotsitaal, Zulu-based Tsotsitaal, Soweto Zulu Slang, Soweto Iscamtho, Tembisa Iscamtho, English and Afrikaans. Sociolinguistic profiles of each of these language varieties were drawn up. These profiles provided clarity on the linguistic diversity in the Black urban speech communities studied and enabled the rendering of a graphic representation of the language situation in Tembisa. The above-mentioned varieties were typologised. Based on language type and language function, the study proposed a model which may be used as a framework for describing the language situation in multilingual Black urban speech communities. The study concludes with recommendations with regard to the need for linguistic analyses of the language varieties used in Black urban speech communities. The implications of the widespread use of these varieties, particularly for education, also deserve further investigation as a matter of urgency...

M.Phil. In order for developers to provide reasonable engineering services as well as a liveable dwelling unit within the existing housing subsidy, a substantial increase in residential density is required. Increased urban densities will decrease engineering services costs due to a greater sharing ability. This study was undertaken in order to quantify the benefits of urban densification on engineering services. The financial problems of Local Authorities in South Africa due to the entrenched culture of non-payment for services, is causing a rapid decline in the sustainability of engineering services due also to low, or non-existent maintenance. The "housing" currently delivered, its nature and continued sustainability are being severely criticized. Few differences exist between the housing currently being delivered and those provided under the previous government. Houses are provided in areas on affordable land normally far from the work place. The type of housing being constructed consists mostly of the single storey, free standing units on separate erven. These types of developments encourage urban sprawl, require very expensive engineering services and discourage the establishment of an economic public transport system. Possible solutions to the workforce/job opportunity problem include mixed land use and residential densification.

M.Comm. Marketers have historically found it convenient to bundle the Asian consumer market together with the black consumer market or the white consumer market depending on the product or event under consideration. As we move toward an era of customised products and individualised service, minority markets become more difficult to overlook. Their unique characteristics demand that they be targeted as separate and unique market segments distinct from the mass markets that dominate the marketing environment.
