Performance management systems help align individual goals and objectives with those of the organisation. The system engages employees and thereby directs them toward achieving the strategic goals of the organisation. The purpose of this research study was to conduct a critical evaluation on the management and implementation of Performance management and development System in the Department of Local Government and Traditional Affairs. Despite the importance of performance management, most organisations find it difficult to implement, manage and sustain performance management systems and processes effectively. It is therefore crucial to ensure adequate planning, evaluation and training is done that will support a sustainable process. Given the strategic role played by the SMS, especially the management of Performance Agreements in the realization of government programmes, it is important that departmental officials make efforts to ensure compliance with its provisions. This study has shown that officials have not been accurate enough in their implementation of the PMDS. The study reveals that there is no staff development programme in place that would help develop staff members to grow in the different fields of their jobs. This is a sound reason why staff responded that they are not happy with the current system. It would appear that management does not devote a great deal of time to staff development. The focus of the PMDS needs to be changed from an output-focused system to a management development system, where there is an increased focus on the development of competencies, compared to the current focus on rewarding only output.

Fleas are one of the major external parasites affecting free range chickens, causing irritation, tissue damage, blood loss and toxicosis which in turn affect quality and quantity of meat and egg production. There are many commercial insecticides available that are effective against fleas. These commercial insecticides have, however become expensive to most resourcelimited farmers and therefore unaffordable, causing farmers to seek low cost alternatives. This study was conducted to document, determine the existence of external parasites in freerange chickens and validate the alternative remedies used in controlling free-range chicken fleas by resource-limited farmers. A questionnaire survey was used to collect data on external parasites of free-range chickens and ethno-veterinary control remedies used by resourcelimited farmers to control these parasites at Amatola basin, in Eastern Cape, South Africa. Resource-limited farmers perceived that mites (79.6%), fleas (64.5%), lice (10.8%) and ticks (6.5%) were problematic parasites of chickens. To control these parasites, resource-limited farmers commonly use ash (28%) madubula (13% carbolic acid) (26.7%), Jeyes fluid (13% carbolic acid) (10%), paraffin (8.4%), used engine oil (2.8%), plants Tagetes minuta, Clutia pulchella, Calpurnia aurea (5.2%) and a few (4.2%) used commercial drugs Karbadust (Carbarly 5%) and mercaptothion 5%. About 7.5% of the respondents used neither of the remedies. To confirm the farmers’ perception on problematic external parasites of free-range chickens a diagnostic survey was conducted. Fifty free-range chickens were randomly selected and examined for external parasites. About 96% of the free-range chickens examined harboured at least one species of external parasites. Fleas (Echidnophaga gallinacea) (50.7%) were the most prevalent followed by lice, Menopon gallinae (12.4%); Menacanthus stramineus (5.3%) and Knemidocoptes mutans (0.57%). Given that Jeyes fluid, used engine oil, paraffin, C. aurea, C. pulchella and T. minuta were mainly used in controlling these parasites, it was important to determine the potential dermal irritant effects of these plants. A dermal irritant effect test was, therefore, conducted using a rat model. Forty eight rats, with parts of the backs shaven, were used to screen the materials for irritation. All the materials tested did not cause any visible skin irritation on rats (p>0.05). Regarding that ethnoveterinary materials were non irritant on rat skin in vitro repellency and contact bio-assay models were used to assess the insecticidal properties of Tagetes minuta, Calpurnia aurea, Clutia pulchella, used engine oil, paraffin and Jeyes fluid on fleas. For the in vitro bioassay T. minuta and Jeyes fluid at 100% concentration demonstrated a repellency level of 76 and 83%, respectively. Tagetes minuta was the most effective among plant materials (p<0.05). Clutia pulchella, C. aurea, used engine oil and paraffin showed insignificant repellency (p>0.05). For the contact bio-assay, C. pulchella, C. aurea and T. minuta at a concentration of 100% resulted in flea mortality of 83.5, 73.3 and 42.5%, respectively. The efficacy of Clutia pulchella compared well with that of Karbadust which had a mean mortality of 97.5%. Paraffin, used engine oil, and Jeyes fluid (19.2%) caused higher flea mortality of more than 82%. In the in vivo study 60 free-range chickens were artificially infested with fleas and test materials were topically applied on infested sites. Test materials exhibited varying flea load reduction efficacy. Used engine oil and Jeyes fluid at 76.8% concentration had a reduction efficacy of 100 and 96% after 3 days post application of test materials. These were not significantly different to that of the positive control Kabadust (carbaryl 5%). The plants C. pulchella and C aurea at 100% concentration had an efficacy of 92 and 77%, respectively. The commonly used remedies by resource-limited farmers to control fleas vary in efficacy. Some of the materials are as effective as the commercial insecticides hence they have a potential to be exploited as insecticides. Further investigations on plant compounds with insecticidal properties and their toxicity, need to be conducted before the plants are recommended for use.

This research explored the nature of conflict that arose in Xolobeni, a small area in the Mbizana Local Municipality in the Eastern Cape Province of South Africa, and the environmental politics emanating from the arguments that supported development rather than environmental protection. The proposed mining project was known as the Xolobeni mining development project within the Amadiba Tribal Authority, an area dominated by Pondos or (Mpondos). The Xolobeni area is located between the Mzamba and Mtentu Rivers, covering some 2 867 hectares, and extends for 20km along the coast of the Mbizana Local Municipality, in the Alfred Nzo District Municipality. In 2005, the Minister of the National Department of Minerals and Energy (DME), now known as the Department of Minerals and Petroleum Resources, announced that an Australian company, Transworld Energy and Minerals (TEM) will establish a mining development project in Xolobeni to mine red sand dunes which are contained within five blocks, each named after the river at its southern boundary. These blocks were Mtentu, Sikombe, Kwanyana, Mnyameni and Mphalane. According to the Minerals and Petroleum Resources Development Act (Act 28 of 2002), the Department of Minerals and Energy is the sole custodian of the mining licence and therefore the only Department that issues mining licences. The research investigated the nature of conflict that erupted in Xolobeni after this announcement, resulting in the formation of two groups namely, the Amadiba Crisis Committee (ACC) which represented the communities who were against the mining project in the area and the Xolobeni Local Community (Xolco) which was a Black Economic Empowerment company that represented the communities that supported the mining project and was to receive 26 percent of the proceeds from the mining company. The purpose of the Amadiba Crisis Committee was to channel complaints and grievances of local residents emanating from the mining development project and other development to all relevant authorities so that the Constitutional rights of residents can be respected. The research also investigated the role of each stakeholder in the proposed mining project, namely, local communities in the area, environmentalists, councillors, the National Department of Minerals and Energy, the National Department of Environmental Affairs and Tourism, the Eastern Cape Department of Economic Development and Environmental Affairs (DEDEA), the traditional authority and the Eastern Cape Provincial Legislature Portfolio Committee on Economic Development and Environmental Affairs. Central to this research was the level of consultation during the proposed mining project. Qualitative and quantitative research methodologies were used to collect data in Xolobeni. Interviews were conducted with the two opposing groups and other various stakeholders including the chieftaincy, environmentalists, councillors and officials in the Department of Economic Development and Environmental Affairs (DEDEA). The researcher used questionnaires in order to get the views of the targeted participants. Eighty questionnaires were distributed among the targeted participants but only forty five were returned. Some of the participants were reluctant to participate in this study because the mining project had not taken place. Secondary data from the Departments of Environment of Affairs nationally and provincially revealed that the Department of Minerals and Energy through its Minister, Bulelwa Sonjica, awarded the mining licence despite recommendations of both Departments not to do so. The Minister of the new Department of Mineral Resources, Susan Shabangu, withdrew the licence and gave three months to Transworld Energy and Minerals to address the outstanding issues raised in the environmental impact assessment (EIA). The data collected revealed that the proposed mining project affected all communities in the Amadiba Tribal Administrative area. The research also illustrated how the Xolobeni community organised themselves and protested against development that intended to force them to relocate from their ancestral land without proper consultation. Issues of sustainable development and environmental protection also formed part of the discussions in this research. While the mining project had stalled, it emerged that the majority of respondents in the area did not want the mining project to proceed.

Thesis (MMed)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: OBJECTIVE The aim of this study is to establish the frequency of unlicensed and off label drug use in infants admitted to the neonatal intensive care unit (NICU) in Tygerberg Hospital. METHOD This was a prospective descriptive survey conducted over 3 consecutive months (September 2011-November 2011) of all medicine charts of neonates admitted during this time period to the NICU. Data collected included demography, diagnoses, medicines prescribed according to dose, frequency, route of administration and indication. Medicine use was defined as unlicensed, licensed or off label use according to the latest South African Medicines Formulary (2012) and the manufacturer’s package insert. Unlicensed drug use is per definition a drug not registered with South African Medicine Control Council (SA MCC) for children and off label drug use is where the use is outside of its authorized license with SA MCC. RESULTS There were 112 neonates enrolled in the study, of whom 51% were preterm and 49% term infants. The most common diagnoses on admission for the preterm babies were hyaline membrane disease (33%) and sepsis (21%), while it was hypoxic ischemic encephalopathy (42%) and post-operative care (22%) for term infants. There were 759 drug events of which 37% were licensed and followed all the licensing terms, 51% were prescribed in an off label manner and the remaining 12% were of unlicensed drugs. The most common reasons off label drug use were for weight (74%), followed by age (44%), frequency (44%), indication (21%), or a route not described in the licensing terms (13%). There was a lack of pediatric data for 9% of the drugs prescribed. In 203 drug events (27%) a drug was used in an off label manner for more than one reason. Sixty one percent of the drugs used had no information on the use of the drug in neonates. CONCLUSION This is the first study conducted in an African NICU, according to our knowledge and the results are similar to studies conducted in Europe and America. Neonates are exposed to a significant proportion of unlicensed and off label drugs. Neonatal clinical trials should be conducted to address the need for proven safe and efficacious treatment for neonates.

Thesis (DPhil)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Urban agriculture (UA) has always been practised in African urban centres. Only since the turn of the twentieth century, however, have development researchers turned their attention to its potential as a sustainable source of food security. Notwithstanding the initial optimism in this regard, many have questioned whether UA is viable and whether it does deliver the benefits that many espouse. This is because most of the benefits are evaluated in terms of their economic viability or amount of produce grown to sustain a family, and often ignore what benefits may be found beyond this. What this dissertation argues is that there are a range of physical and social benefits that accrue from UA that cannot necessarily be measured. Research on the ground suggests that the benefits of UA are more complex than supposed, as confirmed by a number of qualitative case studies on UA in Africa. Much attention is given to the food security and income dimensions of UA. There are, however, also ecological, empowerment and gender dimensions. Throughout Africa, UA is used primarily for food and economic security, through eating produce and trading it on the informal market. The economic benefits of UA, however, are least available to the poor and to women, due primarily to resource limitations, tenure insecurity and patriarchal cultures. While such findings suggest that the benefits of UA bypass those who need them most, it is found that these limitations may be overcome with support from non-governmental organisations (NGOs). NGOs play a key role in promoting sustainable livelihoods. This is achieved through injections of resources and investing in human and social capital. In Cape Town, UA has been supported by NGOs for many years. More recently, local government has supported this effort with a UA policy that legitimises public support through resource donations and the provision of land. The question this dissertation sought to investigate was to what extent UA is contributing to the livelihoods of those living in Cape Town‟s largest low-income area, the Cape Flats. As many of the UA projects in Cape Town are run by NGOs, the focus was on a selection of these projects. In-depth interviews and focus group discussions were held with NGOs and cultivators throughout the Cape Flats. Four different types of cultivation feature, namely home cultivators, cultivation groups, institutional cultivators and garden centres. Home cultivators operate on a small scale on the property around their dwelling, while cultivation groups and institutional cultivators use larger tracts of land. Cultivation groups operate independently, usually on council land, while institutional cultivators cultivate on behalf of the institution whose land they use. All cultivators are supported by the NGO‟s garden centres, the administrative hub of their UA programme. The findings show that some benefits of UA relate largely to the type of UA being practised. For home cultivators, UA strengthens relationships and expands networks. Institutional plots teach children to care for the environment. The economic and food security benefits of UA are evident in formal groups, and NGO-led local garden centres play a supportive role for all cultivators. Other benefits are felt by all cultivators. For example, cultivators from all types stated that UA had taught them to eat healthily and to care for the environment, and all cultivators felt an increased sense of self-worth. Furthermore, all cultivators gave produce away to those around them. A prerequisite for these benefits, however, is successful cultivation, which is only possible with the training and support offered by the NGOs. The findings suggest that NGOs are vital both for ensuring that UA has the greatest impact in low-income areas and for avoiding the limitations of UA that are evident throughout Africa. Nevertheless, the uptake and sustainability of UA in Cape Town are limited by bureaucratic hurdles to land access, limitations of donor funding and widespread attitudes of dependency in its target areas. It is therefore likely that the expansion of UA in Cape Town will remain slow until such limitations are addressed. / AFRIKAANSE OPSOMMING: Stedelike landbou (SL) is nog altyd in die stedelike sentrums van Afrika beoefen. Dis egter eers sedert die begin van die twintigste eeu dat ontwikkelingsnavorsers aandag geskenk het aan SL se potensiaal as ‟n volhoubare bron van voedselsekerheid. Ondanks die aanvanklike optimisme in hierdie verband, het baie bevraagteken of SL moontlik is en of dit die voordele wat baie voorstaan, oplewer. Dit is omdat die meeste van die voordele geëvalueer is in terme van hul ekonomiese potensiaal of die opbrengs om „n familie te onderhou en ignoreer dikwels watter ander voordele daar mag wees. Wat hierdie proefskrif betoog is dat SL 'n verskeidenheid fisiese en sosiale voordele inhou, wat nie noodwendig gemeet kan word nie. Navorsing op grondvlak dui daarop dat die voordele van SL meer kompleks is as wat veronderstel word, soos bevestig deur 'n aantal kwalitatiewe gevallestudies van SL in Afrika. Baie aandag word aan die voedselsekerheid en inkomste dimensies van SL gegee. Daar is egter ook ekologiese, bemagtigings- en geslagsdimensies. Regdeur Afrika word SL hoofsaaklik vir voedselsekerheid en inkomste gebruik, deurdat die produkte geëet word en op die informele mark verhandel word. Arm mense en vroue put egter die minste ekonomiese voordele uit SL, hoofsaaklik as gevolg van hulpbronbeperkings, verblyfregonsekerheid en patriargale kulture. Terwyl sulke bevindinge daarop dui dat die voordele van SL diegene omseil wat hulle die meeste nodig het, is daar gevind dat hierdie beperkings deur ondersteuning van nieregeringsorganisasies (NRO‟s) oorkom kan word. NRO‟s speel ‟n belangrike rol in die bevordering van ‟n volhoubare lewensbestaan. Dit word bereik deur middel van skenkings van hulpbronne en belegging in menslike en sosiale kapitaal. In Kaapstad is SL vir baie jare al deur NRO‟s ondersteun. Onlangs het die plaaslike regering hierdie poging ondersteun deur ‟n SL-beleid wat openbare steun deur helpbronskenkings en die voorsiening van grond legitimeer. Die vraag wat hierdie proefskrif ondersoek het, is in watter mate SL bydra tot die lewensbestaan van diegene wat in Kaapstad se grootste laeinkomstegebied, die Kaapse Vlakte, woon. Omdat baie van die SL-projekte in Kaapstad deur NRO‟s bestuur word, was die fokus op ‟n seleksie van hierdie projekte. Diepte-onderhoude en fokusgroepgesprekke is met landbouers en NRO‟s dwarsoor die Kaapse Vlakte gehou. Vier verskillende tipes landbou kom voor, naamlik tuislandbouers, landbougroepe, institusionele landbouers en tuinsentrums. Tuislandbouers werk op ‟n klein skaal op die grond rondom om hulle woning, terwyl die landbougroepe en institusionele landbouers groter stukke grond bewerk. Landbougroepe werk onafhanklik, gewoonlik op grond wat aan die standsraad behoort, terwyl institusionele landbouers namens die instansie wat se grond hulle gebruik, verbou. Alle landbouers word deur die NRO-tuinsentrums ondersteun. Hierdie tuinsentrums dien ook as die administratiewe sentra van die NRO‟s se SL-program. Die bevindinge toon dat die voordele van SL verband hou met die tipe SL wat beoefen is. Vir die tuislandbouers versterk SL verhoudings en brei dit netwerke uit. Institusionele tuine leer kinders om vir die omgewing te sorg. Die ekonomiese en voedselsekerheidsvoordele van SL was duidelik in formele groepe, en die NRO-tuinsentrums speel ‟n ondersteunende rol vir al drie tipes. Die landbouers het ook ander voordele ervaar. Byvoorbeeld, alle soorte landbouers het genoem dat SL hulle geleer het om gesond te eet en vir die omgewing te sorg en ook dat hulle ‟n verhoogde gevoel van eiewaarde ervaar. Verder het al die landbouers van hulle oes aan mense rondom hulle weggegee. ‟n Voorvereiste vir hierdie voordele was egter suksesvolle verbouing, wat net moontlik was met die opleiding en ondersteuning wat deur die NRO‟s aangebied is. Die bevindinge dui daarop dat NRO‟s noodsaaklik is om te verseker dat SL die grootste impak in lae-inkomstegebiede kan hê, en om die beperkings van SL wat dwarsdeur Afrika duidelik is, te vermy. Nogtans word die opname en volhoubaarheid van SL in Kaapstad beperk deur burokratiese prosedures met betrekking tot toegang tot grond, beperkings van donateurs op befondsing en ‟n wydverspreide staat van afhanklikheid in die teikengebiede. Dit is dus waarskynlik dat die uitbreiding van SL in Kaapstad stadig sal bly totdat sodanige beperkings aangespreek is.

Thesis (MSc)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: A common topographical feature of the Nama-Karoo are mesas, commonly known as "platkoppies" , that provide an interesting source of landscape heterogeneity to an otherwise flat landscape. Although these isolated mesas are geologically and edaphically distinct from the surrounding flats, many species are shared between these habitats. These include palatable species such as Themeda triandra. A question asked by the broad umbrella project under which this project falls was: to what extent do mesas provide refuges for palatable species that are under pressure from heavy overstocking on the surrounding flats? A study on the regeneration potential of T triandra on and off the Tafelberg Mesa in the Middelburg district of the Eastern Cape, South Africa, was undertaken within the context of a broader umbrella project "Restoration of degraded Nama-Karoo: role of conservation islands". The Nama-Karoo has had centuries of heavy commercial livestock production and it is considered to have been transformed from a relatively (by arid ecosystems) productive system to one dominated by shrubs and somewhat less productive species. Themeda triandra is one of the preferred grass species for livestock production. Although T. triandra is a preferred grass species, relatively, little is known about its ability to produce viable seed and the establishment of seedlings particularly in restoration and rehabilitation programmes. This study examines the pattern of seed production and seedling survival, seed dispersal, seed germination, and the morphological and ecophysiological variability of T. triandra, a species with great potential for restoration of degraded Nama-Karoo sites, particularly those in the Eastern Cape. Themeda triandra was found to be one of the dominant species on summit of the Tafelberg Mesa. In comparison, it occurred in small isolated populations on the flats surrounding the mesa. The flats and slopes are grazed more intensely by domestic livestock than the summit of the mesa. This is due to the inaccessibility to livestock due to a steeper topography and the lack of water at the higher altitudes. Annual seed production of T. triandra per plant and per m2 was highest for the populations on the flats despite these populations being grazed most intensively. Rainfall had an effect on annual seed production, which was monitored over two years. Rainfall increased from less than 20mm in November 1999 to 125, 110, 50 and 135mm in December 1999, January 2000, February 2000 and March 2000 respectively. With the increased rainfall prior to the May 2000 sampling period, more seeds were produced per plant and per m2 for the flats and slopes habitats of the Tafelberg Mesa. The opposite trend occurred on the summit of the mesa, where seed production actually decreased. This could be attributed to increased competition or to lower grazing intensities. Increase in rainfall also had a positive effect on the cover of other grasses (excluding T. triandra) and T. triandra itself. Despite higher levels of seed production in populations of T. triandra on the flats, seedling survival was clearly low whereas seedlings on the slopes and summit had significantly higher seedling survivorship. This negative impact could be explained due to the trampling effect of domestic herbivores. The results of a seed dispersal experiment clearly suggest that the seed dispersal distance of T. triandra to "safe" microsites is short distance (majority of seeds disperse up to 60cm) and that the dispersal agent is wind. Microsites for re-establishment was found to be open or rocky sites. In a controlled experiment, seed emergence of T. triandra indicated that optimal sowing depths varied with soil type. Maximum germination was achieved at sowing depth 2cm and 3cm in soil collected from the flats surrounding the Tafelberg Mesa. The soil texture of the flats was found to be more sandy loam clay. The flats had slightly higher content (%) of stone, clay, silt and sand compared to the soils collected from the summit and slopes. Themeda triandra is clearly not limited in its expansion onto the flats in the Middelburg district due to soil conditions at the germination/recruitment phase. This study also revealed that T. triandra germinates best under summer conditions when the probability of rainfall is at its highest. Results with T. triandra seed did not convincingly suggest that smoke water is of adaptive significance to boost germination in restoration attempts in the Middelburg district of the Eastern Cape. In a controlled greenhouse experiment, individuals of T. triandra taken from the summit of Tafelberg Mesa showed no differences in photosynthesis, stomatal conductance or transpiration rates to individuals occurring on the flatland areas surrounding the mesa. Themeda triandra appears to be relatively adaptable to a range of temperature conditions. These findings suggest that there should be no problem using seed from mesa summits in restoration programmes on the surrounding flats. This study revealed no conclusive evidence, indicating that the populations on the summit of the mesa were a source of T. triandra seed for the flats surrounding the Tafelberg Mesa. However, this two year long investigation found that T. triandra has the potential to be used in restoration and rehabilitation programmes. If released from grazing pressures, and assuming favourable climatic conditions, the density of T. triandra on the flats can be increased and can be used as a suitable species for the restoration of heavily degraded patches in the Nama-Karoo Region. / AFRIKAANSE OPSOMMING: OnAlgemene topografiese kenmerk van die Nama-Karoo is mesas, plaaslik bekend as "platkoppies", wat Oninteressante bron van landskap ongelyksoortigheid voorsien aan On andersins vlakte landskap. Alhoewel hierdie geisoleerde mesas geologies en biofisies verskillend is van die omliggende vlaktes, word baie plant spesies gedeel tussen hierdie habitats. Hierdie sluit in smaaklike spesies soos Themeda triandra. OnVraag gevra deur die groter restorasieekologieprojek waaronder hierdie navorsingsprojek resorteer was: tot watter mate dien mesas as ° n hawe aan vreetbare spesies wat onder druk is van swaar oorbeweiding in die omliggende vlaktes? OnStudie van die regenerasie potensiaal van T. triandra op-en-vanaf die Tafelberg Mesa in die Middelburg distrik van die Oos-Kaap, Suid-Afrika, was onderneem binne die verband van die wyer herstelekologieprojek "Herstel van oorbeweide Nama-Karoo weiveld: die rol van bewaringseilande". Die Nama-Karoo was vir honderde jare al blootgestel aan swaar kommersiële lewende hawe produksie en is klaarblyklik verander van ° n relatiewe produktiewe sisteem na 'n ekosisteem gedomineerd deur struike en enigsins minder produktiewe spesies. Alhoewel dit ° n verkiesde grasspesie is bo ander inheemse grasse as weigras, is min bekend oor die fertiliteit van T. triandra sade of oor die vestiging van saailinge, veral in veldrehabilitasie programme. Hierdie studie ondersoek die patrone van saadproduksie, saadverspreiding, saadontkieming, en die morfologiese en ekofisiologiese veranderlikheid van T. triandra, ° n spesie met groot potensiaal vir die herstel van oorbeweide Nama-Karoo terriene van veral die Oos-Kaap. Themeda triandra was een van die dominante spesies op die kruin van die Tafelberg Mesa. Dit kom voor in klein geïsoleerde populasies op die uitgestrekte vlaktes rondom die mesa. Die vlaktes en hange van die mesa word op groot skaaloorbewei deur lewende hawe in vergelyking met op die kruin van die mesa. Dit is te wyte aan die onbereikbaarheid van die mesa vanweë Onsteiler topografie, asook die gebrek aan standhoudende water op die mesa's self. Jaarlikse saad produksie van T. triandra per plant en per m2 was die hoogste vir die populasies op die vlaktes, ten spyte daarvan dat hierdie populasies intensief bewei word. Reënval het 'n effek op jaarlikse saad produksie gehad wat oor twee jaar gekontroleer was. Met die vermeerdering van reënval voor die Mei 2000 proeftydperk, was meer sade geproduseer per plant en per m2 op die vlaktes en hange van die Tafelberg Mesa. Die teenoorgestelde patroon het voor gekom op die kruin van die mesa, waar saadproduksie afgeneem het. Laasgenoemde kan toegeskryf word aan die toename in kompetisie. Toename in reënval het ook 'n positiewe effek gehad op die bedekking van T. triandra self sowel as van ander grasse. Ten spyte van hoër vlakke van saadproduksie, is saailing oorlewing in T. triandra populasies op die vlaktes duidelik negatief terwyl saailinge op die hange en kruin 'n betekenisvolle hoër saailing oorlewingsskap gehad het. Die negatiewe impak kan verduidelik word deur die vertrappings-effek van lewende hawe. Die resultate van die saadvespreidingeksperiment toon dat die saadverspreiding afstand van T. triandra na 'veilige' mikroterreine kort is (die meerderheid van die sade is tot minder as 60cm versprei). Wind is die verspreidingsagent. Dit is gevind dat oop of klipperige terreine gunstige mikroterreine vir hervestiging van T. triandra is. In die gekontroleerde-eksperiment het saadverskyning van T. triandra aangedui dat die optimale saai-diepte wissel met grondsoort. Maksimum ontkieming is behaal by saaidiepte van 2cm en 3cm in die grond versamel in die vlaktes rondom die Tafelberg Mesa. Die grondtekstuur op die vlaktes is 'n sanderige leem-klei. Die vlaktes het effens hoër persentasies klip, klei, slik en sand vergelyke met die grond versamelop die kruin en hange. Themeda triandra is duidelik nie as gevolg van grondtoestande beperk in sy uitbreiding op vlaktes in die Middelburg distrik by die ontkieming/werwing fase. Gondtoestande tydens die ontkiemingsfase is duidelik niw beperkend op die gigthede van T. triandra op die vlaktes nie. Hierdie studie maak bekend dat T. triandra die beste ontkiem onder somer toestande wanneer die waarskynlikheid van reënval op sy hoogste is. Rookwater het geen effect op die ontkiemingspotensiaal van T. triandra in die Middelburg streek van die Oos-Kaap nie. Pogings om T. triandra saad se ontkieming met rookwaterekstrak te bevorder was onsuksesvol. In die gekontroleerde eksperiment het individue van T. triandra op die kruin van Tafelberg Mesa geen verskil getoon in fotosintese, huidmondjie begeleiding en transpirasie tempo nie in vergelyking met individue wat voorkom op die vlaktes rondom die mesa. Themeda triandra blyk relatief aanpasbaar te wees aan 'n wye reeks van temperatuur toestande. Hierdie bevindings dui aan dat daar geen probleem hoef te wees om sade van die kruin van die mesa te gebruik in hervestigig-programme in die omliggende vlaktes nie. Hierdie studie verskaf geen bewyse wat aandui dat die T. triandra bevolkings op die kruin van die mesa as Onbron van saad vir die vlaktes rondom die Tafelberg Mesa dien nie. Hierdie twee-jaar ondersoek vind dat T. triandra 'n potensiaal het om gebruik te word in herstel en rehabilitasie programme. As dit aan ligter weidingsruk onderwerp is en gunstige klimaatstoestande heers, kan T. triandra hervestig word op die vlaktes en gebruik word as Onplantspesie om erg beskadigde areas in die Nama-Karoo streek te herstel.

Thesis (MS en S)--Stellenbosch University, 2002. / ENGLISH ABSTRACT: According to certain writers urban regeneration as an idea encapsulates both the perception of city decline (in local economies, in the use of land and buildings, in the equality of the environment and social life) and the hope of renewal, reversing trends in order to find a new basis for economic growth and social wellbeing. Rebuilding the city, clearing away obsolete buildings and vacant sites, and producing new building forms and designs symbolised the renewal in action. But urban regeneration also has different components or evolution criteria like, the major strategy (the focus of the renewal project), an economic focus, a social content, a physical emphasis or an environmental approach. The economic change that occurred in cities throughout the world in the past decade, has been paralleled not only by the physical reshaping of the city, but it has been accompanied by institutional restructuring (the rise of new firms, new working practices and relationships designed to exploit new market opportunities). The physical, economic, social and cultural projects launched through the process of urban regeneration, reconstruct the economic, socio-cultural, political-institutional and physicalenvironmental fabric of cities. It battles urban decay and redevelop the city to such a extend that it brings back the original appeal of the city, which lured people to the central city for decades. But not all urban renewal projects are aimed at the inner city; some are launched in a much wider context and would focus on blighted or previously disadvantaged and marginalised areas. Renewal projects in Cape Town and elsewhere in South Africa in cities like Durban and Johannesburg are still ongoing and form an important part of rebuilding cities of modem South Africa. It is however important to remember that not all urban renewal projects proved to be a success, some do fail. In the Cape Town Metropole and the Central City local government has neglected many areas for much too long. Recent efforts to restore the beauty of Cape Town and really address the urban challenges that arose from the Apartheid legacy shows a commitment from the Cape Town Municipality to create a much more liveable and economic viable urban environment. This study investigated the City of Cape Town Municipality's approach towards urban regeneration in the Central Business District and other specific business nodes. A literature review gave an intellectual background to the study and helped to build a logical framework. Secondary analysis helped define the goal of the study and qualitative field research assisted the investigation through direct observation and semi-structured interviewing. The study did not aim to prove that every urban renewal project that was launched was aimed at eradicating the problems associated with the Apartheid City. An important factor to take in account is that different business areas (The Victoria and Alfred Waterfront) and nodes (The Wetton-Landsdowne Phillipi Corridor), the focus of this study, make use of different redevelopment strategies. This study focused on how and why some work and must be built upon, and delivered critique on why some failed and should convert to a more successful renewal approach. The study concluded that the City of Cape Town's approach towards urban regeneration do compare positively with redevelopment strategies followed in other parts of the world such as America and Britain. The study tried to show the direction urban regeneration could take for the future, based on an evaluation of urban regeneration evolution criteria namely: • The major strategy and orientation and key actors and stakeholders. • The economic focus. • The social content. • The physical emphasis. / AFRIKAANSE OPSOMMING: Stedelike vernuwmg omvat beide die konsep stedelike verval (met betrekking tot plaaslike ekonomieë, die fisiese gebruik van grond en gebou en wat betref die kwaliteit van die omgewing) en die hoop van vernuwing of herontwikkeling, met die idee om die rigting van strategie te verander sodat 'n nuwe basis vir ekonomiese groei en sosiale welstand gevind kan word. Die herontwikkeling of opbou van die stad beteken nie net die verwydering van nuttelose en ongebruikte geboue en vakante grond nie. Stedelike hernuwing het verskeie komponenete of evolusie kriteria, soos die hoof strategie (die fokus van die hernuwingsprogram), 'n ekonomiese fokus, 'n sosiale inhoud, 'n fisiese klem of 'n omgewingsbenadering. Die ekonomiese verandering wat oor die laaste dekade in die wêreld plaasgevind het is vergesel nie net deur 'n fisiese herstrukturering van die wêreld se hoof stede nie, maar ook institusionele hervorming (die opkoms van nuwe firmas en venootskappe en nuwe ekonomiese en mark geleenthede) Die fisiese, ekonomiese sosiale en kulturele komponente wat deel vorm van stedelike hernuwingstrategieë dra by tot die heropbou en herontwikkeling van die ekonomiese, sosiokulturele, polities-institusioneel en fisiese-omgewingsfabrikaat van stede. Stedelike verval word beveg en die stad word tot so 'n mate herontwikkel dat dit die oorspronklike aantrekkingskrag van die stad herstel. Maar nie alle hernuwingstrategieë is gemik op die Sentrale Sakekern nie, sommige word in 'n wyer konteks geloods, en fokus op areas van verval, vorige benadeelde en gemarginaliseerde areas met as doelwit 'n meer interkonnektiewe stad. Hernuwingsprojekte word steeds op 'n konstante basis geloods in stede soos Kaapstad, Durban en Johannesburg met die oog op die belangrike herontwikkeling van kern areas in die stede. Dit is egter belangrik om in ag te neem dat nie elke stedelike hernuwingsprojek 'n seker sukses is nie, soos die Wetton-Landsdowne Phillipi Korridor Program. Binne die Kaapse Metropool en in die Sentrale Sakekern is kern areas vir lang tye verontagsaam en toegelaat om te verval. Die onlangse pogings (1999 - 2002) wat aangewend word deur die Kaapstad Munisipaliteit dui op 'n verbintenis van die organisasie se kant aftot stedelike hernuwing. Die organisasie, deur middel van die Stedelike Hernuwingsprogram van 2002, is ook verbind tot areas wat voorheen deur Apartheidsbeleid benadeel en gemarginaliseer is. Hierdie studie fokus op Kaapstad se benadering tot stedelike hernuwing in die Sentrale Sakekern en ander spesifieke besigheidsnodusse. 'n Literêre oorsig het gehelp om die intellektuele agtergrondmateriaal en logiese raamwerk van die studie te vorm. Sekondêre analise het die doel Stellenbosch University http://scholar.sun.ac.za van die studie bepaal en kwalitatiewe veldwerk het die ondersoek aangehelp deur observasie en semi-gestruktureerde onderhoude. Die studie sal nie probeer bewys dat elke hernuwingsprojek wat deur die Kaapstad Munisipaliteit geloods word gemik is op die uitwis van stedelike probleme geassosieer met die Apartheidsbeleid nie. Die evaluasie aan die einde van die studie poog om dit uit te wys. Dit is belangrik om te beklemtoon dat elke verskillende area wat die potensiaal toon vir herontwikkeling soos die Victoria en Alfred Waterfront of die Wetton-Landsdowne Phillipi Korridor (die fokus van die studie) volg verskillende strategieë ten einde hul hernuwingsdoelwit te bereik (ekonomiese ontwikkeling, sosiale fokus of omgewingsbeklemtoning). Die studie het wel die gevolgtrekking gemaak dat van Kaapstad se stedelike hernuwingstrategieë tog ooreenstem met herontwikkelingstrategieë in die res van die wêreld soos in Amerika en Brittanje. Die studie fokus en poog ook om die rigting aan te dui vir toekomstige stedelike hernuwingstrategieë op grond van 'n evaluering van stedelike hernuwingsevolusie kriteria naamlik: • Die hoofstrategie en rolspelers. • Die ekonomiese fokus. • Die sosiale inhoud en • Die fisiese beklemtoning van hernuwingselemente.

Thesis (MBA)--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The Chevron Cape Town refinery was constructed in 1996 with a crude capacity of 100,000 barrels per day (bpd). The focus of the unit is production and meeting the nameplate market demand. The project environment for the refinery is that of maintenance and gradual upgrade. The majority of projects handled are small capital projects. The aim of this research is to identify what the success criteria for project management should be for projects carried out within the small capital projects department of Chevron's Cape Town refinery. An important distinction to make is that this study looks at project management success and not project success, although the aspects of project success will be discussed to highlight how closely related the two concepts are. Project success is not directly proportional to project management success and neither is project management success directly proportional to project success. In the past decades, project management success was usually indicated by the project completion within the time, cost and performance constraints (Kerzner, 2004:29). This has now evolved to understanding all the objectives of the project. Project management can still be deemed successful even if it did not meet all the objectives of the project and vice versa, as long as there are mutual trade-offs agreed to by the developer (project manager) and the client. White and Fortune (2002:1-11) conducted a survey to identify common criterion used for defining project management success. The three criteria identified for judging project success are completion on time, within the budget and to performance (specification). Project management success has been found to be a very difficult topic to define. This research report shown that project management success needs to be moved beyond the iron-triangle to other criteria like safety and meeting the objectives of the client. What was evident was that criteria, factors, dimensions and measures are concepts widely used by researchers and it is hoped that these topics. A very interesting discovery during my first interview was that project management success comes in three phases or parts, which are pre-delivery, delivery and post-delivery. What was evident from this research was that the criteria for project management success need to be established up front before the project gets to the delivery phase. There is no way that one can measure project management success when the success criteria one is looking for at the end of the project have not been established up front. The case study is summarised using the diagram in chapter five showing the new project management success criteria that needs to be adopted by the refinery. Future research into project management success criteria could include a survey which could go out the whole refinery and not just the representative sample who were interviewed for this report which could confirm the project management criteria found in this report. / AFRIKAANSE OPSOMMING: Die Chevron Kaapstad raffinadery is in 1996 gestig met 'n ruolie kapasiteit van 100,000 vate per dag. Die fokus van die eenheid is produksie en om aan die marknavraag te voldoen. Die projekomgewing van die raffinadery is instandhouding en mettertydse opgradering van die raffinadery. Die meerderheid van projekte wat hanteer word is klein-kapitaalprojekte. Die doel van hierdie navorsing is om te identifiseer wat die sukseskriteria vir projekbestuur behoort te wees vir projekte wat binne die klein-kapitaaldepartement van Chevron se Kaapstad raffinadery behartig word. 'n Belangrike onderskeid om te maak is dat hierdie studie na projekbestuursukses kyk en die projeksukses nie, alhoewel die aspekte van projeksukses ook bespreek sal word om uit te lig hoe naby verwant die twee konsepte aan mekaar is. Projeksukses is nie direk proporsioneel tot projekbestuursukses nie en omgekeerd. In die afgelope dekades was projekbestuursukses gewoonlik aangedui deur die afhandeling van die projek binne die tydsraamwerk, koste en prestasiebeperkinge (Kerzner, 2004:29). Hierdie konsep het intussen uitgebrei na 'n verstaan van al die doelwitte van die projek. Projekbestuur kan steeds as suksesvol beskou word al het dit nie aan al die doelwitte van die projek voldoen nie, en omgekeerd, solank as wat daar wedersydse toegewings deur beide die ontwikkelaar (projekbestuurder) en die kliënt gemaak word. White en Fortune (2002:1-11) het 'n opname gemaak om die algemene kriteria te identifiseer wat gebruik word om projekbestuursukses te definieer. Die drie kriteria wat uitgewys is om 'n projek te evalueer, is afhandeling van die projek binne die tydsraamwerk, koste en prestasiebeperkinge. Projekbestuursukes is 'n baie moeilike onderwerp om te definieer. Hierdie navorsingsverslag wys dat projekbestuursukses verby die “yster-driehoek” moet beweeg om ander kriteria soos veiligheid en die voldoening aan die kliënt se doelwitte, in te sluit. Wat duidelik na vore gekom het is dat kriteria, dimensies en metings konsepte is wat wyd deur navorsers gebruik word. 'n Baie interessante ontdekking gedurende die eerste onderhoud was dat projekbestuursukses in drie fases of dele voorkom, naamlik voor-lewering, lewering en na-lewering. Wat duidelik uit die navorsing is, is dat die kriteria vir projekbestuursukses voor die aanvang van 'n projek vasgestel moet word, voordat die projek die afleweringsfase bereik. Daar is geen manier wat projekbestuursukes gemeet kan word wanneer die sukseskriteria wat aan die einde van 'n projek gesoek word, nie aan die begin vasgestel is nie. Die gevallestudie word opgesom deur die diagram in hoofstuk vyf te gebruik wat die nuwe projekbestuursukseskriteria aandui wat deur die raffinadery aanvaar moet word. Toekomstige navorsing in projekbestuursukseskriteria kan 'n opname insluit wat aan die hele raffinadery gestuur kan word en nie net die verteenwoordigende steekproef met wie daar vir hierdie verslag se doeleindes onderhoud gevoer is om die projekbestuurkriteria van hierdie verslag te bevestig nie.

Thesis (PhD)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: The Swartland region in the western Cape, South Africa, covers approximately 5000 km2 and forms part of the Pan-African Saldania Belt that represents the southernmost extremity of the Pan-African orogenic belts in southern Africa. Regional mapping of the Swartland area shows that lithologies can be classified using predominantly structural and to a lesser extent lithological criteria. This led to the proposal of a new classification, were rocks of the previous classification of the Malmesbury Group are divided into two new groups, namely the Swartland and Malmesbury groups. The Swartland group can be divided into the Berg River and Moorreesburg formations, a series of quartz-chlorite-muscovite-feldspar schists, quartz schists, graphitic schists and limestones; and the Bridgetown formation, a series of metavolcanic rocks with WPB-MORB affinities that possibly represent seafloor. Deposition of the sediments is suggested to have occurred concurrently with deformation in an accretionary prism/fore-arc and was initiated with the opening of the lapetus Ocean at ca. 600 Ma. This early deformation event, Dt (ca. 575 Ma), only affected the Swartland group and exhibits pervasive bedding transposition, thrusting and imbrication of units creating a tectonostratigraphic sequence. Where identified, kinematic indicators and fold vergence indicate a top-to-the-west transport direction during the early, low-angle Di deformation. The Malmesbury group overlies the Swartland group, being locally separated by an unconformity. The Malmesbury group is a succession of conglomerates, grits and shales (Piketberg Formation), grading into greywackes, shales, siltstones, sandstones and minor limestones of the Tygerberg and Porterville formations. Sedimentation probably commenced after ca. 575 Ma and lasted until shortly after 560 Ma. Both the Swartland and Malmesbury groups were then deformed by the deformation event, D2 (ca. 552-545 Ma), and were intruded by the 552 to 510 Ma Cape Granite Suite. The Franschhoek Formation, formally part of the Malmesbury Group is now classified, along with the inferred ca. 535-510 Ma Magrug and Populierbos Formations of the previous Klipheuwel Group. The redefined Klipheuwel group documents a change in depositional environment from the continental slope/ocean trench, marine and flyschoid deposits of the Malmesbury group to continental, fluvial half-graben and graben deposits. Exhumation, extensive erosion and the formation of a peneplain, was followed by the deposition of the Table Mountain Sandstone Group around 550-510 Ma. The Spitskop gold prospect, located 10 km south of Piketberg, represents the first identified occurrence of mesothermal gold mineralisation in the Saldania Belt. Metamorphic devolatilisation of the Swartland group during Di led to the scavenging and transportation of gold along shallow-dipping shear zones that are contained within the early, sub-horizontal So/Si tectonic fabric. Pervasive fluid movement in the Spitskop area led to elevated gold values compared to background values throughout the lithologies at Spitskop. The lack of any economic-grade gold mineralisation is probably related to the absence of suitably orientated structures, such as high-angle faults, that are commonly believed to represent the prerequisite for large fluid throughputs that could result in economic-grade gold deposits. The mineralisation at Spitskop, however, provides a genetic model for further exploration of gold in the Swartland group. / AFRIKAANSE OPSOMMING: Die Swartland streek in die Wes-Kaap, Suid-Afrika, beslaan ongeveer 5000 km2 en vorm deel van die Pan-Afrikaanse Saldania-gordel wat die mees suidelike deel van die Pan-Afrikaanse orogene gordels in suidelike Afrika verteenwoordig. Regionale kartering van die Swartland streek dui aan dat die gesteentes geklassifiseer kan word deur oorwegend strukturele, en tot 'n mindere mate litologiese kriteria te gebruik. Gevolglik word ‘n nuwe klassifikasie voorgestel, waar gesteentes volgens die vorige klassifikasie van die Malmesbury groep verdeel word in twee groepe, naamlik die Swartland en Malmesbury groepe. Die Swartland groep kan verdeel word in die Bergrivier en Moorreesburg formasies, ‘n reeks kwarts-chloriet-muskoviet-veldspaat skis, kwarts skis, grafitiese skis en kalksteen; en die Bridgetown formasie, ‘n reeks metavulkaniese gesteentes met WPB-MORB affiniteite wat moontlik oseaanvloer verteenwoordig. Daar word voorgestel dat afsetting van die sedimente gelyktydig plaasgevind het saam met vervorming in ‘n akkresionere prisma/voorboog, geinisieer deur die opening van die lapetus Oseaan (ca. 600 Ma). Hierdie vroee vervorming, Di (ca. 575 Ma), het slegs die Swartland groep geaffekteer en vertoon deurdringende verplasing van gelaagdheid, oorskuiwing en imbrikasie van eenhede en het ‘n tektonostratigrafiese opeenvolging gevorm. Waar identifiseer, dui kinematiese aanwysers en plooi kanteling op ‘n bokant-na-wes beweging gedurende die vroee, lae hoek Di vervorming. Die Malmesbury groep oordek die Swartland groep, plaaslik geskei deur ‘n diskordansie. The Malmesbury groep bestaan uit ‘n opeenvolging konglomeraat, grintsteen en skalie (Piketberg formasie), wat gradeer in grouwak, skalie, sliksteen, sandsteen en ondergeskikte kalksteen van die Tygerberg en Porterville formasies. Sedimentasie het waarskynlik begin na ca. 575 Ma en het voortgeduur tot kort na 560 Ma. Beide die Swartland en Malmesbury groepe is hierna vervorm deur D2, (ca. 552-545 Ma) en daaropvolgend ingedring deur die 552 tot 510 Ma Kaap Graniet Suite. Die Franschhoek Formasie, voorheen deel van die Malmesbury Groep, word nou geklassifiseer tesame met die afgeleide ca. 535-510 Ma Magrug en Populierbos formasies as deel van die voorheen geklassifiseerde Klipheuwel groep. Die hergedefinieerde Klipheuwel groep dui op 'n verandering in afsettingsomgewing vanaf die kontinentale glooiing/oseaantrog, mariene en flyschoiede afsettings van die Malmesbury groep na kontinentale, fluviale half-graben en graben afsettings. Herblootstelling, omvattende erosie en die vorming van ‘n skiervlakte is gevolg deur die afsetting van die Tafelberg Sandsteen Groep random 520-510 Ma. Die Spitskop goudvoorkoms, 10 km suid van Piketberg, verteenwoordig die eerste identifiseerde voorkoms van mesotermale goudmineralisasie in die Saldania Gordel. Metamorfe ontvlugtiging van die Swartland groep gedurende Dt het aanleiding gegee tot die roofuitruiling en vervoer van goud langs laaghellende skuifskeursones in die vroee, subhorisontale S0/Si tektoniese maaksel. Deurdringende vloeistofbeweging in die Spitskop omgewing het aanleiding gegee tot verhoogde goudwaardes in vergelyking met agtergrond waardes dwarsdeur die litologiee by Spitskop. Die gebrek aan ekonomiese graad goud mineralisasie is waarskynlik verwant aan die afwesigheid van geskikte georienteerde strukture, soos hoe hoek verskuiwings, wat oor die algemeen beskou word as ‘n voorvereiste vir die toevoer van groot hoeveelhede vloeistof wat kon aanleiding gegee het tot ekonomiese graad goudafsettings. Die mineralisasie by Spitskop verskaf egter 'n model vir verdere goud eksplorasie in die Swartland groep.
