  • Description: The purpose of this study is to ascertain whether the clients who make use of the services of the Psychology Clinic at Rhodes University perceive the masters students being trained at the Clinic as providing adequate psychotherapy. Using a sample of 18 clients, who underwent psychotherapy at the Rhodes Psychology Clinic during 1990, a follow-up study was conducted to ascertain the perceived success of that psychotherapy. Those variables most pertinent to the outcome of psychotherapy are examined. The study uses both qualitative and quantitative methodology and shows that, overall, 89% of the clients who participated in this study perceived the psychotherapy at the Rhodes Psychology Clinic to be satisfactory. The study also highlights those factors which were perceived to be negative in the psychotherapeutic equation and it is hoped that the findings can be beneficial in planning more efficient services for the Clinic in the future. , Thesis (MA) -- Faculty of Humanities, Psychology, 1993

  • Description: There have been several attempts to explore Shakespeare's debt to Erasmus, notably Waiter Kaiser's in Praisers of Folly (1964), which concentrates on the figure of Falstaff. But on account of the Christian-Classical tradition both writers share, and on account also of Erasmus's widespread influence in the sixteenth century, direct borrowing is generally hard or impossible to prove.

  • Description: This thesis attempts to evaluate the role of the World Bank in Sub-Saharan Africa's development. It argues that the World Bank has stepped beyond the boundaries of a typical lending institution by linking its aid to political reform. The study argues that in this capacity the Bank has contributed to the halting democratization process currently underway in Africa. The economic effects of the World Bank's Structural Adjustment Programmes have been less successful. As yet, the programmes have not produced the expected results and there is no evidence of long-term, sustainable economic recovery in Sub-Saharan Africa. These programmes are, however, long-term strategies and it may therefore be too premature to reach a final conclusion. They may also have been affected negatively by unfavourable political environments. This study, noting the negative effects of the international terms of trade and prices for African exports, concludes that although economic recovery in Sub-Saharan Africa will be facilitated by domestic political and economic policy reform, there is also a need for reform of the international economic order. The World Bank has correctly identified the need for domestic improvement, but it has a tendency to disregard the negative consequences of the existing structure of the international economy.

  • Description: Suppes beweer dat "All teachers everywhere recognise the help that books give them in teaching students. The day is coming when computers will receive the same recognition. Teachers look on computers as a new and powerful tool for helping them to teach their students more effectively." In hierdie ondersoek word gepoog om op die voordele van die aanwending van een mikrorekenaar as hulpmiddel vir die onderwyser vir die onderrig van wiskunde, te wys. Die belangrikste oorwegings in die ondersoek was: 1. Efektiwiteit van die metode. 2. Bekostigbaarheid van die metode. Die effektiwiteit van hierdie metode van onderrig word hoofsaaklik bepaal deur die geskiktheid van die programmatuur. Programmeringsvaardighede aan die kant van onderwysopgeleide persone versterk hierdie oorweging. Deurdat slegs een mikrorekenaar gebruik word, word deels aan die tweede oorweging, naamllk bekostigbaarheld, voldoen. Programmeringsvaardighede, soos hierbo genoem, kan ook bydra tot die besparing van koste deurdat bogenoemde programmatuur 'intern' ontwikkel word. Die wens word uitgespreek dat hierdie metode van onderrig tot voordeel van die totale leerlingbevolking van die land aangewend sal kan word.

We obtain results which are to a large extent analogous to results given in a series of papers of Šostak (where L = M = [0,1]) but not necessarily with analogous proofs. Often, our generalizations require a variety of techniques from lattice theory e.g. from continuity or complete distributive lattices.

  • Description: The influence of modern technology on education is becoming more noticeable and has implications for the curriculum and the teaching methods of mathematics. The microcomputer can be used effectively as a powerful teaching and learning aid within the mathematics classroom. This study considers the role of the computer as an aid to teachers and pupils in the teaching and learning of mathematics and shows it as having great potential. At present relatively few schools in South Africa are using the computer as a teaching aid in the mathematics classroom. The researcher proposes that some reasons are a shortage of suitable programs, the fact that few teachers have adequate skills in educative uses of the computer and most teachers are not skilled in programming techniques. Based on this assessment of the problem, spreadsheet programs related to some mathematics lessons, together with teaching notes and pupils' material have been developed. Besides describing the potential of the computer in mathematics, this study outlines the development of three spreadsheet packages and suitable teaching methodologies used for each package, and assesses an action research investigation undertaken by the researcher, teachers and pupils when using these spreadsheet packages in six classes. The findings of the investigation are most encouraging. The overall conclusion is that computer spreadsheet packages can assist the teacher in making the learning of mathematics more effective, more interesting and more enjoyable.

  • Description: The purpose of this study is to investigate the value of using a Daseinsanalytic approach to dream explication in order to reveal the essential meaningfulness of behaviourial possibilities for the patient. After discussing the Daseinsanalytic view on dream explication, emphasizing Medard Boss's approach as the major exponent of this view, the study explores the usefulness and validity of the study as a method of investigating the dreams from this perspective. The dreams related in this study are examined individually, giving a phenomenological understanding of each and also providing a possible prospective focus for therapy. It will be shown that the phenomenological understanding of the patient's dreams corresponds with his subjective experience of his emotional existential situation and that any positive changes in the content of the dreams over time corresponds with observable and related changes in his behaviour, ideation and mood. However, if the suggested prospective focus of Medard Boss had been more usefully employed when each dream was explicated in the therapy sessions, it is felt that the progress of therapy would have been greatly enhanced. This study therefore concludes that the use of Medard Boss's approach to dream explication has not only a hermeneutic value in the process of therapy, but also aids the dreamer in becoming aware of the possible modes of behaviour yet unrevealed in his waking life.

  • Description: This study concentrates specificaUy on assessing those elements of private and external costs and benefits which need to be accounted for in analyzing the role of electricity supply in a developing region. To facilitate this aim, three interrelated questions are addressed. The first question examines the reasons why a critical need for electrification in developing areas exists. In this regard, a selective review of the literature on development economics is offered, illuminating the previous neglect of the rural dimension in development and the associated problems of poverty and inequality, a lack of infrastructure and the general inability to fulfill basic needs. The second question is devoted exclusively to an economic analysis of the supply of electricity in developing areas. A broad theoretical review on whether an unregulated or regulated (private or public) sector should be responsible for the provision of electrification is presented. This evaluation highlights the various welfare implications and efficiency considerations that appear to be relevant in the present context. The final question, which constitutes the central proposition of the thesis, establishes how electrification should be supplied in developing areas. To this end, the conditions specific to a region in Venda are discussed. An attempt is made to identify the private and external costs and benefits relating to electricity supply and the corresponding costs and benefits pertaining to alternative sources of energy. Since the incidence and nature of these costs and benefits could only be ascertained from individual households, it was deemed necessary to undertake a questionnaire study of residents in Makwarela township and its periurban settlement of Lufule-Tshisele. A number of basic trends were evident from the research results. As far as the various benefits are concerned, respondents tended to place a much higher value on both the private and external benefits associated with electricity than its alternatives. At the same time, the survey found that although the private (or monetary) cost of electricity far exceeded the corresponding cost of alternative energy sources, the external costs were significant in the case of alternative energy sources, but virtually non-existent in the case of electricity. On the whole, the Venda survey seems to suggest that an economic case can be made for involving the broader community in subsidising the supply of electricity in Makwarela, Lufule-Tshisele and other areas. While such a subsidy can perhaps be justified on distribution grounds alone, and more specifically in terms of the rapid and pronounced effect it is likely to have on the quality of life in the region, its real worth lies in the fact that it may confer certain external benefits on the community.

  • Description: Mapwork is an established part of the geography curriculum, and yet it poses particular problems for pupils and teachers. Maps participate in a complex system of graphic communication: the conceptual abstraction involved in the reading and interpretation of maps requires on the part of pupils a high degree of cognitive and perceptual development; teachers, too, often experience considerable difficulty in imparting the skills necessary for graphic literacy (graphicacy). The peculiar difficulties associated with map reading and the poor performance of pupils in this area have regrettably encouraged an attitude which dismisses mapwork as irrelevant or dispensable in geographical education. Yet graphicacy is essential not only in the learning of geography but in the overall cognitive development of the child, and therefore cannot be excluded from the curriculum. This study attempts to identify some of the specific difficulties experienced by pupils in their attempts to read and interpret maps, and to trace the origin of these difficulties. It argues that the complexity and sophistication of the skills necessary to interpret topographical maps and aerial photographs, for instance, should not be underestimated. Teachers need to be made aware of how pupils acquire map reading skills and of the problems they encounter during this process, so that teaching programmes commensurate with pupils' level of cognitive development can be formulated. It is also important that mapwork be taught in as practical a manner as possible. The findings and recommendations of this study have implications for geography teachers, textbook writers and educational authorities, especially those involved in curriculum and syllabus design.

  • Description: The objective of the research was to determine the extent to which marketing in general, and the Mohair Scheme in particular, played a part in the re-emergence of South Africa as the world's leading mohair producer. The two major components of the Scheme, the 'voorskot', or initial payment, and reserve prices were analysed separately. In an adaptive expectations, distributed lag model of supply adjustment, only the weighted rainfall and the average real net price of mohair during the previous season, were found to be important determinants of mohair production. The significant negative correlation between the average real net 'voorskot' price and mohair production was contrary to expectations, and probably due to the 'voorskot' always having been set well below the market price. The 'voorskot' may nevertheless have played an important part in making the Scheme as a whole acceptable to producers. As no record is kept of the reserve price, its influence was tested indirectly in two stages. In the first, its influence on price stability was determined by a comparison of ranges, standard deviations and variances, and by several multiple linear demand regressions. Three of the four models showed clearly that price stability was increased by the Mohair Scheme. In the second stage, formulae and diagrammatic analyses were used to assess the welfare gains and losses resulting from the Mohair Scheme. There was a welfare gain to local producers and most of the welfare costs of the Scheme were borne by foreign consumers. With this gain to producers and the more stable price, it was concluded that the reserve price had stimulated mohair production. It was therefore established that the Mohair Scheme had played a major part in the re-emergence of South Africa as the world' s leading mohair producer. Nevertheless, in view of the massive stockpiling in recent seasons, because the reserve price was set too high, the result was a substantial loss to the Scheme; it was therefore recommended that the Mohair Scheme be discontinued or, at least, that the reserve price should be set at a much lower long-run, market clearing level.

  • Description: This study examines the dynamics of agricultural change amongst traditional African smallholder farmers in Shixini location, Gatyana District, Transkei. This entailed an examination of the historical, regional and local causes of agricultural change and the response of the local community. What became evident was that there had been a gradual decline in agricultural output after the 1930s due to a combination of socio-economic and environmental constraints. Pressure on limited resources and land degradation, a consequence of socio-economic pressures on the African peasantry and agricultural expansion, reduced carrying capacities and soil fertility within the African reserves. Racially discriminatory policies also reduced African access to agricultural markets and forced peasants into migrant labour. The initial response to this agricultural decline was to maintain cultivation and pastoral practices, despite declining output, and rely more heavily on migrant labour. However, massive population ~owth from the mid 1950s onwards stimulated a rapid change in cultivation practices. Rural households found it increasingly difficult to gain access to arable land in river valleys and growing poverty undermined their ability to cultivate fields. In response to these conditions the rural population abandoned their fields and expanded garden cultivation. Garden cultivation was a more intensive method of cultivation which made more efficient use of household resources, maintained long-term yields and had a less detrimental impact on the soil. This study attempts to make a contribution to southern African historiography and historical geography. Since the rise of radical human geography in the 1970s there has been a growing number of political economy studies focusing on capitalist expansion, racially discriminatory state policies and associated class conflicts in South Africa. However, most of these studies have focused on urban communities. The political economy of African rural areas has been sorely neglected by human geographers despite the enormous growth of such studies amongst historians and other social scientists. This study of agricultural change in Shixini location, Transkei adds to the small collection of geographical research on the political economy of African rural areas. It also adds to the large body of historical research by focusing on the recent past, a much less well documented period. The most important component of the study was an examination of the response of the rural community to socio-economic and environmental changes. This brought the often neglected role of human agency within the world political economy into the study. Environmental factors, often neglected by'historians and human geographers, were also brought into the analysis. The examination of such a broad range of factors was facilitated through the use of a wide variety of source material including historical, anthropological and socio-economic literature, official statistics, archival records, aerial photographs and a sample survey

  • Description: The Hartbees River Thrust Belt (HRTS) is a 40-60 km wide, southwest-vergent zone of complex structure, lithostratigraphy and high-grade metamorphism in the northeastern part of the mid-Proterozoic Namaqua Tectonic Province. The HRTS comprises the boundary zone separating the Bushmanland and Gordonia Subprovinces of the Namaqua Province. A knowledge of the movement histories of major ductile shear zones within the HRTS is fundamental to understanding the tectonic development of the belt, and Namaqua tectogenesis as a whole. In spite of this, no detailed microstructural kinematic studies have been attempted and the movement histories and age relationships of these shear zones have not been described in detail. This thesis represents a detailed microstructural kinematic study of a representative suite of orientated samples of mylonitic rocks, collected from five ductile shear zones within the HRTS. These shear zones include the Neusspruit Lineament, the Kakamas shear zone (KSZ), the Hugosput shear system (HSS), the Rozynenbosch-Ganzenmond shear zone (RGSZ) and the Graafwater shear system (GSS). Accepted modern methods of microstructural kinematic analysis were applied to samples of mylonite from these shear zones, in order to determine the precise orientation of the kinematic vectors, and the sense and relative ages of movements on each of the shear zones. Shear sense criteria, including composite SoC planar fabrics and shear band foliations, asymmetrical porphyroclast systems, mica-fish, oblique grain-shape and subgrain fabrics, asymmetrical microfolds, and the displacement of fractured rigid grains, together with a well-developed mylonite elongation lineation, conclusively indicate that SSW-directed thrusting occurred along the HSS, RGSZ, GSS and possibly along the Neusspruit Lineament, while normal, top-to-NE movements occurred on the Neusspruit Lineament, KSZ and HSS. Rare transposition criteria, and textural and paragenetic contrasts between syn-kinematic fabrics, strongly suggest that the phase of normal, top-to-NE movement seen in the northeastern HRTS shear zones is younger than the more widespread top-to-SW thrusting event. On the basis of mesoscopic structural criteria, SSW-directed thrusting is correlated with the D₂ deformation event in the HRTS. The mylonite zones have been refolded by ENE-SSW trending F₃ crossfolds, whose demonstrated coaxial relationship to the mylonite elongation lineation precluded reorientation of primary kinematic vectors. In the southwestern HRTS, primary thrust vectors have been reoriented by right-lateral, strike-slip shearing adjacent to the Pofadder Lineament during D₄. Simple shear dispersion of mylonite lineations related to normal movement, suggests that they too have been modified by D₄ shearing, and this constrains the timing of extensional movements to post-D₂ and pre- or syn-D₄. Syn-kinematic mineral assemblages, rheological criteria and the annealing states of the mylonites, provide insight into the thermotectonic evolution of the shear zones. A model is proposed in which the movement histories of shear zones within the HRTS are explained in terms of a typical orogenic cycle, involving crustal thickening by thrusting during a compressional orogenic phase, followed by collapse of the thickened crust during an extensional taphrogenic phase.

  • Description: A polarimetric method for monitoring the rate of soluble collagen breakdown by collagenase enzyme action has been developed. The method represents an extension of previous physicochemical techniques based on viscometry, but is simpler and easier to carry out, particularly in the case of reaction rate studies. The method was developed arising from reports of collagenase activity measurement on inappropriate substrates such as gelatin, modified collagens and synthetic polypeptides. The optical method depends on measurement of the loss in optical rotation in solutions of soluble calfskin collagen resulting from initial enzymic cleavage of the collagen trip1e-helix, followed by spontaneous unwinding of the resultant unstable helical fragments. Specific assay conditions were chosen to ensure that the loss in optical rotation following enzymic cleavage was rapid and complete. The method is specific since in the absence of collagenase, non-specific proteinases produce only a limited decrease in solution optical activity. The method has also been compared with established physicochemical assay techniques and compares favourably with both viscometric and titrimetric collagenase assays. The availability of a rapid, sensitive and quantitative procedure for measurement of collagenase activity provides a convenient means for detecting the presence of collagenase in solution and examination of hide bacterial cultures for collagenase production. In addition, a study of biocidal compounds of potential interest in hide preservation for possible inhibitory effects on collagenase is conveniently carried out with the method. Fundamental research into synergistic action in enzymic hydrolysis of collagen is now possible, providing valuable insight into the mechanism of raw hide biodeterioration.

  • Description: This thesis investigates the role of women in the early church as portrayed in 1 Timothy 2:9-15 using the recently-developed method of Rhetorical Analysis. It makes use of a rhetorical approach largely based on the method proposed by Kennedy, supplemented by insights from scholars who have emphasised the argumentative element in rhetoric. This method illustrates how the role of women in the church is decisively determined by the argument in the letter as a whole. A brief survey of classical rhetoric is given. The typical structure of a rhetorical discourse is listed with its component sections. The validity of using rhetorical analysis as a means for interpreting New Testament texts is justified. Textual units are identified from the structure of the text. Rhetorical insights are used to explain how the identified units cohere within the overall structure of the letter and how they relate to one another and interact. The thesis is developed that the section on women and teaching can only be meaningfully investigated in the light of the text as a whole and of the motifs in the letter. The thesis has a special focus on 2:9-15. This section is analysed in more detail than the rest of the text with the exception of 1 Timothy 1. As exordium, the latter provides the introduction to the situation dealt with in the letter, introduces the case, and sets the tone for the rest of the letter. The persuasive power of rhetoric in any situation depends to a large extent on its use of common tradition. The socio-cultural setting of the author is consequently analysed. Finally, the role of women in Graeco-Roman society is analysed in terms of motifs found in 1 Timothy 2:9-15.

  • Description: A case study carried out at Edgewood College of Education (Natal) attempted to demonstrate how in-house training could provide staff with the necessary computer literacy skills to integrate computer technology into lecturing and teaching programmes. The duration of the project was six months and during this time a group of thirty academic staff members were exposed to computer technology via practical experience, lectures and demonstrations. The results gleaned from the project show that most of the staff involved in the project developed sufficient computer skills to be of benefit in their professional and personal tasks.
