Student Number : 9411363J - PhD thesis - School of Medicine - Faculty of Health Sciences / This study on non-compliance with chemotherapy in the oncology patient with a good prognosis was done in the Johannesburg Hospital in South Africa. 114 compliant and 33 non compliant oncology patients with a good prognosis showed significant differences (at the 5% level) on the MCMI2 on the following scales: Disclosure, Debasement, Avoidance, Passive Aggressive, Self-defeating, Schizotypal, Anxiety, Dysthymia, Alcohol Dependence and Major Depression. In a Linear Discriminant Function Analysis . two variables, Debasement and Schizotypal were selected that linearly affected compliance significantly. A linear discriminant model was constructed from the two variables which could predict non compliance in these patients 72.5% of the time. The next step was to construct a treatment model , an intervention which would have some impact on improving compliance. After trial and error with various methods, a Medical Trauma Debriefing Model was worked out and used, based on the Wits Trauma Intervention Model, which up to this time had been used for trauma debriefing of people who had experienced trauma due to violence and abuse on a criminal or political level. This is in accordance with recent studies which are beginning to show the link between PTSD and medical non-compliance. It is suggested that Medical Trauma Debriefing, as a preventative measure, be incorporated automatically and routinely into the treatment of certain medical and surgical conditions, especially in Oncology.

This study was carried out primarily to evaluate the cryo-tolerance of equine semen from four stallions through assessing the spermatozoa motion characteristics with Computer-Assisted Sperm Analysis (CASA). Four stallions were collected during the breeding season (summer). For each ejaculate, fresh and cryopreserved samples were taken for sperm motility characteristics evaluation. Data analysis demonstrated that sperm cells of stallions were significantly affected by (P<0.05) cryodamage. Stallion (A) was cryotolerant, and was classified as a good freezer, whereas stallion (D) was not and classified as a poor freezer regardless of the concentration of sperm. In addition, a concentration of 0.4 x 109 sperm cells/ml had higher percentages of rapid sperm and velocity parameters (P<0.05) compared to 0.8 x 109 sperm/ml. Further research is necessary to identify potential biomarkers for good and poor freezer stallions.

The Birds River Gabbro Complex is intruded into sediments of the Karroo Stormberg Group in the area SW of Dordrecht in the northeastern Cape. A geochemical investigation, restricted to the igneous rock suite, gabbro-ferrogabbro-ferrotholeiite, presents new major-element data as well as data for twelve trace elements - Ba, Sr, Rb, Zr, Y, Nb , Zn, Cu, Ni, Co, V and Cr. The strong degree of differentiation of Kokstad-type tholeiitic magma in the Birds River intrusion, as noted by previous investigators, is revealed in variation diagrams in which data are plotted against a simple index of fractionation. Later differentiates are strongly enriched in Si, Ti, Fe, Na, K, P, Ba, Rb, Zr, Y, Nb, Zn and Cu but depleted in Mg, Ca, AI, Ni, Co and Cr. Extreme differentiation resulted in a strong depletion of Ti, Fe, P, Cu and V in the most highly evolved ferrotholeiites. Field evidence suggests the initial emplacement of strongly fractionated magmatic residua derived from fractional crystallization processes in a magma chamber at depth during cauldron subsidence of a mass of sediments within an annular fracture. These porphyritic, in part glassy, ferrotholeiites are enriched in Si, Na, K, Ba, Zr, Rb, Y, Nb and Zn and were engulfed by a later episode of renewed hypabyssal intrusive activity from the original source area. The younger gabbro was emplaced in a series of closely-spaced heaves or pulses of relatively undifferentiated Kokstad-type magma. The gabbro differentiated in place to form ferrogabbros which chemically closely approximate ferrotholeiite compositions. toidal facies. Residual liquids crystallized as a pegmatoidal facies. A simple fractional crystallization path, modelled on the assumption that the gabbro and ferrotholeiite form a continuous series, indicates that the least evolved ferrotholeiite can be derived from the initial gabbro composition by the fractionation of major amounts of plagioclase and pyroxene but lesser amounts of olivine. Crystallization and removal of magnetite and other Fe-oxides were relatively more important during the later stages of differentiation. The variation of major- and trace-elements in tholeiitic Karroo magma under conditions of strong differentiation at Birds River serves as a framework for the regional study of the geochemistry of other Karroo dolerites and volcanics of the north-eastern Cape. New geochemical data are presented for a sample of thirty chilled and coarse-grained Karroo dolerites collected throughout the north eastern Cape. For the most part, the chilled dolerites are relatively undifferentiated and the average composition differs only slightly from that determined by Walker and Poldervaart (1949). Variation diagrams reveal the steady increase in Si, Al, Ca, Na, K and P and the residual trace elements Ba, Zr, Rb, Y, Nb and Zn with increasing differentiation of the dolerites from more basic types. The concentrations of K, Ba and Rb are highly variable in some Karroo dolerites while new data suggest that Nb levels in the dolerites are low, being generally less than 10 ppm. The strong variation of the K-related elements (K, Ba and Rb) as well as the large ranges determined for certain inter-element ratios, such as K/Rb, Zr/Nb and K/Zr in the chilled Karroo dolerites, suggest that factors other than fractional crystallization processes need to be considered to account for individual variations. Little correlation exists between petrographic type as defined by Walker and Poldervaart (1949) and geochemical character. New geochemical data are also presented for ten Karroo basaltic lavas from the lowermost horizons of the lava sequence exposed in the Barkly East area. Major- and trace-element data indicate that these earliest Karroo extrusives are on average enriched in Si and Rb but depleted in Co and Ni when compared with the averaged chilled Karroo dolerite. Compared with basalts from Lesotho, the Barkly East basalts are enriched in Si but depleted in Ni and possibly Nb, Cu and V. The andesite is markedly enriched in Si, Na, K, Ba, Sr, Rb, Zr and Nb but depleted in Mg, Ca, V, Ni , Cu, Co and Cr. The subdued rate of Ni depletion and the absence of olivine as a major phenocryst phase in the series basalt to andesite, in the Barkly East area, suggests that differentiation trends may be controlled by the fractional crystallization of orthopyroxene and plagioclase, the two common phenocrysts present in these volcanics. The strong depletion of V and Cu in the andesite may indicate some magnetite removal during fractional crystallization.

Includes bibliography. / This dissertation sets up a standardised system for analysing mid-seventeenth to mid- nineteenth century Cape colonial ceramic assemblages and then applies it to a number of Dutch and British historical sites in the south-western Cape region of South Africa in order to trace patterns of change in the availability and use of domestic ceramics in the colony. The system accommodates the wide range of African, Asian and European ceramics used during the period of Dutch East India rule from 1652 to 1795, the following Transitional years when the Cape was governed for short periods by both the British and Dutch governments and the period from 1815 onwards when the Cape became a British Crown Colony. A systematic ceramic classificatory system was required to form a framework for the first stage of a proposed study of the role of Asian porcelain in the Cape during the 17th and 18th centuries. The resulting Cape Classificatory System has five sections. (i) Ware Table, a ware based classification, records ceramics by sherd count and minimum number of vessels, and acts as a check list for Cape colonial sites. (ii) Date Table provides the accepted dates of production and references for all ceramics excavated in the Cape. (iii) Form and Function Table lists excavated ceramics by vessel form within functional categories. (iv) The Site Catalogue accessions and references (where possible) all the ceramics in an assemblage. (v) A catalogue of previously unreferenced Asian market ware (coarse porcelain) excavated from 17th to 19th century colonial sites in the south-western Cape. Thirty ceramic assemblages from Cape colonial sites and four assemblages from shipwrecks in Cape waters were analysed or examined. The Cape Classificatory System was applied in full to the ceramics from four sites: the Granary, a late seventeenth century Dutch East India site; Elsenburg, an elite mid-eighteenth century farmstead; Sea Street, Cape Town, a town midden in use from the last quarter of the eighteenth century to ca. 1830; and a well in Barrack Street, Cape Town, that was open from ca. 1775 till the late nineteenth century. The results clearly demonstrated changes in ceramic availability, usage and discard in the Cape over a two hundred year period, differences in refuse disposal practices and the dependence of the colony on Asian porcelain, including Asian market coarse porcelain, during the late seventeenth century and eighteenth century.

The dissertation emerged from a growing realization that various of the distinctive traits in The Good Soldier could be considered as bearing traces of certain characteristics of Postmodern fiction. The study sets out to scrutinize The Good Soldier for further evidence to support this possibility. The areas that present themselves as specifically promising in this regard concern the issue of epistemology in the novel as well as the use of narratological devices in The Good Soldier. These two issues serve as the main area of focus for the study and are considered for the possible congruencies they demonstrate with Postmodern thought and fictional characteristics. After providing an orientation to the issues of epistemology and narratological devices in the context of Modernism and Postmodernism, the study proceeds to discuss the issue of epistemology in The Good Soldier and its relationship to Postmodern fiction. This involves a discussion of surfaces, simulations, perception, epiphany, history, language and re-enchantment and how these issues are conducive to demonstrating that The Good Soldier bears traces of Postmodern thoughts on knowledge. The use of narratological devices in The Good Soldier are also considered for possible congruencies with Postmodern fiction, specifically regarding the use of narrator, character and chronological sequencing. In this regard the issue of text and intertextuality are discussed and it is discovered that The Good Soldier foregrounds its own status as text through its references to a number of other texts. It is concluded that The Good Soldier does indeed bear traces of a Postmodern epistemology and employs narratological devices plausibly identifiable as Postmodern. The comments on knowledge in The Good Soldier, as well as the use of narrator, character and chronological sequencing are comprehensively elucidated and accounted for in the context of Postmodern epistemology and narratological devices. The Good Soldier is an accepted and well-loved Modernist novel. A study that seeks to scrutinize the text for elements of Postmodernism questions and foregrounds the issue of literary periodization and the division of literary texts on the basis of year of publication and authorship. Demonstrating that The Good Soldier bears traces of Postmodemism through its epistemology and use of narratological devices therefore provides evidence that literary movements are not mutually exclusive and that the traits of one literary period may be beneficial in an elucidation and elaboration of a text belonging to another literary movement. / Thesis (M.A.)--Potchefstroom University for Christian Higher Education, 2001.

Thesis (LLM)--University of Stellenbosch, 2005. / ENGLISH ABSTRACT: It is clear that the classical concept of contract suffers from weaknesses because it takes too little account of social and economic changes that have occurred in our highly competitive global climate. More particularly, it fails to acknowledge implicit dimensions of contract. The classical contract theory was designed for transactions rather than to regulate relations. In view of the relational contract theory, contracts are agreements, often developed gradually, over a period of time and last over a period of time, perhaps indefinitely. As illustrated, with a discussion of the various theories attempting to qualify the classical law, the development of the relational contract theory and the need for implicit dimensions is in line with changes in business, market transactions and the economic and social environment of today. The relational contract is gradual and emphasises the relationship between the parties. Focus is placed on their understandings, party practices, customs and expectations as opposed to formal doctrines and principles. Characteristically, relational contracts are often incomplete in their specifications, thus leaving room for the creation of expectations and understandings inter partes. These expectations and understandings along with co-operation, rationality and trust are the implicit dimensions, which reflect the shared interest the parties have in their transaction. The ways in which these implicit dimensions can be recognised, developed and applied to contracts, particularly in the South African context is considered in light of our law's treatment of the implication of terms into contracts. It was found that considerations of reasonable expectations and policy do playa role in our law, albeit not to such an extent as to meet the demands of the relational contract theory and the recognition of implicit dimensions. Existing contract principles are also evaluated in the light of the relational contract and implicit dimensions. It is not suggested that classical contract law doctrines are to be dispensed with but that a shift of focus should occur, from the traditional focus on the ''paper'' deal to focusing on the ''real'' deal, between the parties. It is concluded that a principle of good faith would be a suitable starting point to give cognisance to implicit dimensions and to regulate relational contracts. In recognising a principle of good faith, the courts will be able to better respond to the expectations of the parties. A principle of good faith is recommended as being advantageous towards developing a pre-contractual duty of disclosure and encouraging more co-operative thinking and dealing in both legal doctrine and contracting practice. / AFRIKAANSE OPSOMMING: Dit is vandag duidelik dat die klassieke kontraksmodel aan swakhede ly omrede dié model nie genoegsaam rekening hou met sosiale en ekonomiese veranderinge mons hoogskompeterende wêreldklimaat nie. Meer bepaald, neem die model nie die implisiete aspekte van kontrakte in ag nie. Die klassieke teorie is meer gepas vir eenmalige transakies tussen kontraktante en nie soseer gebruik vir die regulering van deurlopende kontraksverhoudinge nie. In terme van die verhoudingskontrakteorie ("relational contract theory") word kontrakte beskou as ooreenkomstes wat geleidelik, oor 'n lang tydperk kan duur, miskien selfs vir 'n onbepaalde tydperk. Soos gei1lustreer, is daar verskeie teoriëe wat poog om die bestaande klassieke benadering aan te pas. Die ontwikkeling van die verhoudingskontrakteorie en die implisiete aspekte van kontrakte korreleer met veranderinge in internasionale handel en die ekonomiese en sosiale omgewing van vandag. Die verhoudingskontrakteorie beklemtoon die verhouding tussen die partye, hul praktyke en gewoontes en verwagtinge en is nie net slegs op formele beginsels gebaseer nie. 'n Eienskap van hierdie kontraktstipe is dat hulle dikwels nie poog om die verhouding van die partye volledig te reguleer nie. Sodoende word ruimte gelaat vir die ontwikkeling van verwagtinge en implisiete verwagtinge tussen die partye. Hierdie verwagtinge en verstandhoudings te same met die beginsels van samewerking, redelikheid en onderlinge vertroue, is die implisiete aspekte wat die gemeenskaplike belang wat partye in hul verhouding het, weerspieël. Maniere om hierdie implisiete aspekte te herken, te ontwikkel en toe te pas, veral in die Suid- Afrikaanse konteks, is oorweeg in die lig van ons reg se benadering tot die inlees van onuitgesproke bedinge in kontrakte. Alhoewel daar bevind is dat redelike verwagtinge en beleid wel 'n rol speel, is dit onvoldoende in die lig van die eise van die verhoudingskontrakteorie en die behoefte aan implisiete aspekte. Bestaande kontraksbeginsels is ook geëvalueer in die lig van die verhoudingsgebaseerde kontrak en implisiete aspekte. Daar word nie gesuggereer dat klassieke beginsels van die hand gewys moet word nie. Eerder dan die tradisionele fokus op die "paper deal" moet die fokus op die"real deal" wees. Ten slotte word die behoefte aan die erkenning van 'n beginsel van goeie trou uitgelig. Breedweg sal howe beter kan reaggeer op partye se verwagtinge en verstandhoudinge en dié beginsel word ook aanbeveel met die oog op die behoefte aan samwerking tussen partye en die ontwikkeling van 'n voor-openbaarmakingsplig.
