- Description: South Africa and Canada have emerged from a history fraught of inequalities, which were characterised by segregationist practices. Such inequalities have served as an epitome of discrimination taking place in the society and the workplace in both countries. Both South Africa and Canada had their discrimination affecting black peoples (Africans, Indians and Coloureds) and Aboriginal peoples (Indians, Inuits or Métis) respectively, women and people with disabilities. In both countries discrimination has polarised society. It is against this backdrop that both countries have attempted to eliminate unfair discrimination through the promulgation of relevant legislation that seeks to, inter alia, provide the regulatory framework in respect of employment discrimination. With the foregoing in mind, the purpose of this work is the provision of a selection of comparable aspects of employment discrimination in Canada and South Africa. This selection comprises discrimination on the basis of race, gender, sex, pregnancy, age and HIV/AIDS. The study uses, as its departure point, both countries’ constitutional framework to elicit the extent to which protection against unfair discrimination is extended to the workforce. Apart from looking at the constitutional provisions towards the elimination of unfair discrimination, reference is made to specific employment statutory provisions in order to provide a comprehensive and explicit picture of how workplace discrimination in both countries is regulated. The study focuses on substantive law from both countries about the above -mentioned aspects of discrimination. This is informed by the very nature and scope of the study because any concentration on procedural and evidentiary aspects of discrimination could lead to failure to achieve the objectives of the study. It also looks at specific Canadian and South African case law, judgments of the courts and jurisprudence in the field of employment discrimination in order that the reader is presented with a clearer picture of recent developments in addressing workplace inequalities.

- Description: New hardware devices are continually being released to the public by hardware manufactures around the world. For these new devices to be usable under a PC operating system, device drivers that extend the functionality of the target operating system have to be constructed. This work examines and compares the device driver architectures currently in use by two of the most widely used operating systems, Microsoft’s Windows and Linux. The IEEE1394 (high speed serial bus) device driver stacks on each operating system are examined and compared as an example of a major device driver stack implementation, including driver requirements for the upcoming IEEE1394.1 bridging standard.

- Description: Increasing pressure from national government to improve throughput at South African tertiary education institutions presents challenges to educators of introductory programming courses. In response, educators must adopt effective methods and strategies that encourage novice programmers to be successful in such courses. An approach that seeks to increase and maintain satisfactory throughput is the modification of the teaching model in these courses by adjusting presentation techniques. This thesis investigates the effect of integrating an experimental iconic programming notation and associated development environment with existing conventional textual technological support in the teaching model of a tertiary level introductory programming course. The investigation compares the performance achievement of novice programmers using only conventional textual technological support with that of novice programmers using the integrated iconic and conventional textual technological support. In preparation for the investigation, interpretation of existing knowledge on the behaviour of novice programmers while learning to program results in a novel framework of eight novice programmer requirements for technological support in an introductory programming course. This framework is applied in the examination of existing categories of technological support as well as in the design of new technological support for novice programmers learning to program. It thus provides information for the selection of existing and the design of new introductory programming technological support. The findings of the investigation suggest strong evidence that performance achievement of novice programmers in a tertiary level introductory programming course improves significantly with the inclusion of iconic technological support in the teaching model. The benefits are particularly evident in the portion of the novice programmer population who have been identified as being at risk of being successful in the course. Novice programmers identified as being at risk perform substantially better when using iconic technological support concurrently with conventional textual technological support than their equals who use only the latter form. Considerably more at risk novice programmers using the integrated form of technological support are in fact successful in the introductory programming course when compared with their counterparts who use conventional textual technological support only. The contributions of this thesis address deficiencies existing in current documented research. These contributions are primarily apparent in a number of distinct areas, namely: • formalisation of a novel framework of novice programmer requirements for technological support in an introductory programming course; • application of the framework as a formal evaluation technique; • application of the framework in the design of a visual iconic programming notation and development environment; • enhancement of existing empirical evidence and experimental research methodology typically applied to studies in programming; as well as • a proposal for a modified introductory programming course teaching model. The thesis has effectively applied substantial existing research on the cognitive model of the novice programmer as well as that on experimental technological support. The increase of throughput to a recommended rate of 75 percent in the tertiary level introductory programming course at the University of Port Elizabeth is attributed solely to the incorporation of iconic technological support in the teaching model of the course.

A comparison of the effectiveness of the judicial doctrine of "substance over form" with legislated measures in combatting tax avoidance

- Description: Taxation statutes often provide opportunities for tax avoidance by taxpayers who exploit the provisions of the taxing statute to reduce the tax that they are legally required to pay. It is, however, important to distinguish between the concepts of tax avoidance and tax evasion. The central issue, especially where the contract has no business purpose, is whether it is possible for the substance and legal form of the transaction to differ to such an extent that a court of law will favour the substance rather than the legal format. The debate is whether the courts should be encouraged to continue with their "judge-made" law or whether the tax jurisdictions should be supporting a legislative route as opposed to a judicial one, in their efforts not only to combat tax avoidance but also to preserve taxpayer certainty. The question is whether the Doctrine of "Substance over Form" as applied by the judiciary is effective in combating tax avoidance, or whether a legislated general anti-avoidance provision is required. An intensive literature survey examines the changes which have occurred in the application of judicial tests from the 1930's to date and investigates the different approaches tax jurisdictions follow in order to combat tax avoidance. The effect of the introduction of anti-avoidance provisions in combating tax avoidance is evaluated by making a comparison between the United Kingdom and South Africa. [n the United Kingdom, the courts are relied on to create anti-tax avoidance rules, one of which is the Doctrine of "Substance over Form". The doctrine is very broad and identifies various applications of the doctrine, which have been developed by the courts. In South Africa, the Doctrine of "Substance over Form" has been applied in certain tax cases; however the South African Income Tax Act does include anti-tax avoidance sections aimed at specific tax avoidance schemes, as well as a general anti-tax avoidance measure enacted as section 103. The judicial tests have progressed and changed over time and the introduction of anti-avoidance legislation in the Income Tax Act has had an effect on tax planning opportunities. A distinction needs to be made between fraudulent and bona fide transactions while recognising the taxpayer's right to arrange his or her affairs in a manner which is beneficial to him or her from a tax perspective. Judicial activism and judicial legislation in the United Kingdom has created much uncertainty amongst taxpayers and as a result strongly supports the retention of a general anti-avoidance section within an Income Tax Act. A general anti-avoidance provision, following a legislative route, appears to be more consistent and effective in combating tax avoidance.

- Description: The nature of Internet and Intranet Web applications has changed from a static content-distribution medium into an interactive, dynamic medium, often used to serve multimedia from back-end object-relational databases to Web-enabled clients. Consequently, developers need to make an informed technological choice for developing software that supports a Web-based application for distributing multimedia over networks. This decision is based on several factors. Among the factors are ease of programming, richness of features, scalability, and performance. The research focuses on these key factors when distributing images from an Oracle9i database using Java Servlets, JSP, ASP, and ASP.NET as the server-side development technologies. Prototype applications are developed and tested within each technology: one for single image serving and the other for multiple image serving. A matrix of recommendations is provided to distinguish which technology, or combination of technologies, provides the best performance and development platform for image serving within the studied envirorunent. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Supply chains encompass all of the diverse activities that are associated with the flow and transformation of goods, right from the beginning stage of the raw materials, all the way through to the consumer. Supply chains are broken into three distinct parts, namely upstream activities involving the material and service inputs from suppliers, internal activities involving the manufacture and packaging of the goods, and downstream activities, which involve the distribution and sale of the goods. Since the inception of the automotive industry, buyers and suppliers have been linked in rigid, inflexible relationships. With the advent of the Internet, however, supply chains are becoming less rigid and more efficient. E-enabling an automotive supply chain involves two distinct spheres of interest, namely, the sphere of automotive supply chains and that of e-business. Both spheres are evolving fast and becoming increasingly complex. Due to the increasing complexity, there is a lack of understanding with regard to incorporating e-business principles effectively into automotive supply chains. In order to address this lack of understanding, the dissertation proposes a conceptual framework that can be used to assist in the process of e-enabling an automotive supply chain. Before the dissertation ventures to propose this conceptual framework, a number of challenges that may be encountered when attempting to enable an automotive supply chain are highlighted. The proposed framework, therefore, specifically aims to position activities conceptually in such a way that it can be argued that the identified challenges are considered at the appropriate time in the e-enabling process. The framework therefore, focuses on the entire process, starting at the planning phase and going right through to the implementation phase. As such, the framework consists of various phases, with each phase containing a myriad of activities. The different phases of the framework include developing a strategic business plan, designing an information technology architecture, identifying system and resource requirements, creating a project plan and finally implementing the project. These phases aim to address the entire e-enabling process. The contribution that this dissertation makes is in the form of a conceptual framework which may be followed during the e-enabling process. The framework aims to provide direction and to ensure that the many activities that are involved in the e-enabling process are considered. The dissertation also highlights the many challenges that may be encountered when enabling a supply chain. Lastly a prototype application has been developed using a new Internet technology. The prototype has been developed in order to ascertain the new technologies suitability to the e-enabled supply chain environment.

- Description: The interaction between farmers, agricultural scientists and extension workers is sometimes overlooked in agricultural entomology. In an attempt to respond to this reality this study examines some foundation of this interaction in relation to the pest management practices of subsistence and small-scale farmers and also highlights the problems that might arise in the implementation of IPM. Problems involving pests occurrence; language barriers; beliefs, knowledge and perception about insects, and visual literacy are examined. The thesis has a two-fold focus, firstly the study of pests on cabbages of subsistence farmers in Grahamstown and secondly a broader focus on other aspects such as cultural entomology, perception of insects and visual literacy specifically in relation to Xhosa speaking people in the Eastern Cape. The most important crop for emergent farmers in the Eastern Cape are cabbages, which have a variety of pests of which diamondback moths and are the most important. Traditional pest management practices tend to influence the development of IPM programmes adopted by these farmers. Eastern Cape farmers apply periodic cropping systems, which had an effect on the population densities of diamondback moth (DBM), other lepidopteran pests and their parasitoids. Considering the maximum population densities of DBM, which were 0.2 - 2.9 larvae/plant, there were no major pest problems. The availability of parasitoids, even in highly disturbed and patchy environments, showed good potential for biological control. Since some extension officers cannot speak the local farmers’ language, a dictionary of insect names was formulated in their language (isiXhosa) to assist communication. Response-frequency distribution analysis showed that the dictionary is essentially complete. The literal translations of some names show that isiXhosa speakers often relate insects to people, or to their habitat or classify them according to their behaviour. Farmers from eight sites in the Eastern Cape were interviewed regarding their knowledge and perception of insect pests and their control thereof. To some extent, farmers still rely on cultural control and have beliefs about insects that reflected both reality and superstition. There is no difference between the Ciskei and Transkei regions regarding insect-related beliefs. Farmers generally lack an understanding of insect ecology. There is a need for farmers to be taught about insects to assist with the implementation of IPM. Leftover pesticides from commercial farms or detergents are sometimes used to manage the pests. When training illiterate or semi-literate farmers, it is important to understand their media literacy so as to design useful graphic and object training media. Generally farmers showed that they either understand graphic or object media depending on the features of the insects being looked at. These findings are discussed with regard to the potential development of IPM training material for subsistence and small-scale farmers in a community.

Since some extension officers cannot speak the local farmers’ language, a dictionary of insect names was formulated in their language (isiXhosa) to assist communication. Response-frequency distribution analysis showed that the dictionary is essentially complete. The literal translations of some names show that isiXhosa speakers often relate insects to people, or to their habitat or classify them according to their behaviour. Farmers from eight sites in the Eastern Cape were interviewed regarding their knowledge and perception of insect pests and their control thereof. To some extent, farmers still rely on cultural control and have beliefs about insects that reflected both reality and superstition. There is no difference between the Ciskei and Transkei regions regarding insect-related beliefs. Farmers generally lack an understanding of insect ecology. There is a need for farmers to be taught about insects to assist with the implementation of IPM. Leftover pesticides from commercial farms or detergents are sometimes used to manage the pests. When training illiterate or semi-literate farmers, it is important to understand their media literacy so as to design useful graphic and object training media. Generally farmers showed that they either understand graphic or object media depending on the features of the insects being looked at. These findings are discussed with regard to the potential development of IPM training material for subsistence and small-scale farmers in a community.

- Description: This study is an investigation of Xhosa English as used by teachers in the Grahamstown area of the Eastern Cape. The aims of the study were firstly, to compile a 20 000 word mini-corpus of the spoken English of Xhosa mother-tongue teachers in Grahamstown, and to use this data to describe the characteristics of Xhosa English used in the classroom context; and secondly, to assess the usefulness of a corpus-based approach to a study of this nature. The English of five Xhosa mother-tongue teachers was investigated. These teachers were recorded while teaching in English and the data was then transcribed for analysis. The data was analysed using Wordsmith Tools to investigate patterns in the teachers' language. Grammatical, lexical and discourse patterns were explored based on the findings of other researchers' investigations of Black South African English and Xhosa English. In general, many of the patterns reported in the literature were found in the data, but to a lesser extent than reported in literature which gave quantitative information. Some features not described elsewhere were also found. The corpus-based approach was found to be useful within the limits of pattern-matching. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The de-industrialisation process that was a common feature of North America and Western Europe in the 1970s, through into the 1980s has become an observable feature in African countries and South Africa in particular in the last two decades. Globally, hard hit areas include those associated with the early Industrial Revolution characterised by mass production and the agglomeration of iron and steel, coal and textile industries. General changes in the global market, especially the falling demand for extractive heavy minerals like coal and gold have also affected many countries region and localities. In the case of South Mrica, the previous high economic dependence on mined minerals like coal and gold has resulted in many once prosperous mining regions of the country being reduced to a shadow of their former selves. The worst affected areas in South Africa are those of the Klerksdorp Goldfields in the North West Province and Free State Goldfields, with the latter alone losing 100,000 jobs during the 1990s. This trend has also been acute in the coal-mining industry of the KwaZulu-Natal province since the late 1970s. The firms that had grown in the shadow of the major mining company supplyipg machinery, or who processed the semi-manufactured product are also severely affected by the closing down and restructuring in the mining and iron industries. These industries have often been forced to close down because of a break in the vital connections they developed with these mining industries. Such localised economic crisis has encouraged the universal trend towards the devolution of developmental responsibilities to the local governments and other local stakeholders to - empower them to respond to these changes. This study investigated the local economic initiatives which have been undertaken in the three municipalities of north-western KwaZulu Natal i.e. Utrecht, Dundee and Dannhauser to respond to the closures which have taken place in the mining industry of this region, which used to be among the most prosperous coal mining regions of South Africa. Using their new developmental mandate the local governments, in partnership with the communities and other external interveners have tried to respond to these localised economic crisis and also indirectly to the general poverty and underdevelopment, which characterises this region of KwaZulu-Natal. The effects of apartheid policies, and previous discriminatory rural development policies in, particular, and the Regional Industrial Development policy, which was intensively applied in the 1980s by the pre-1994 government regime, have further compounded the magnitude of the challenge. The lack of capacity in some municipalities has constrained successful implementation of Local Economic Development has led to some communities acting alone to face their situation with or without external intervention.

- Description: This research study seeks to examine the impact of Outcomes-Based Education (OBE)from a developmental perspective in the Eastern Cape. Two schools were selected as research sites, one from a previously advantaged area and the other from a previously disadvantaged area. These schools were evaluated on their understanding of OBE and its relationship to development. OBE was introduced in South Africa under controversial circumstances because of the legacy of apartheid education from which we are coming. Because of that, schools in South Africa reflect the inequalities that are resulting from apartheid legislation. In 1994 the government introduced the Reconstruction and Development Programme (RDP) to eradicate all the discrepancies resulting from apartheid. On the educational sphere, OBE was the curriculum policy aimed at eradicating the legacy of apartheid education. The then Minister of Education was convinced that OBE or Curriculum 2005 would be a developmental approach to education and would take South Africa into the 21st century. Ever since its introduction, educators have encountered many problems with the implementation of OBE, especially in the previously disadvantaged areas of the Eastern Cape. The researcher used semi-structured interviews to collect data from the respondents. However, one set of questionnaires was prepared for the educators, students, parents and education government officials. Because of the qualitative nature of the questionnaire the data collected was also analyzed qualitatively. Each question was analyzed from each of the focus groups and the researcher established findings that were analyzed in relation to the literature review. The researcher then was able to reach his own conclusions on the impact that OBE has on the South African education system and recommendations on what could be done for OBE to be successfully implemented and to be developmentally effective in previously disadvantaged areas of South Africa. The recommendations propose useful interventions, which could be made by the government to assist all the stakeholders involved in education in both an understanding and better implementation of OBE in Previously Disadvantaged Areas (PDA’s). They include provision of support to stakeholders and that teachers should be taught about the relationship between OBE and reconstruction. The research study focuses mainly on OBE and its relationship to development in urban or Previously Advantaged Areas (PAA’s) of two Eastern Cape schools. It will be relevant to the Eastern Cape Education Department in its efforts to implement OBE in schools and it could be a source of knowledge to educators. The conclusion that has been reached, however, is that there is a lot of ignorance about this new system of education to both educators and parents. There is also evidence of ignorance to matters pertaining to the relationship between OBE and it’s relationship to the Reconstruction and Development Programme (RDP). A major recommendation that is made then is that for OBE to be relevant in the South African context, it should help to improve the lives of ordinary people in South Africa, especially in Previously Disadvantaged Areas.

A critical examination of the income tax provisions relating to the taxation of foreign income of residents as defined

- Description: The Budget speech of 23 February 2000 by the Minister of Finance marked the introduction of significant changes to the income tax system of the Republic of South Africa (Republic). A residence-based system of taxation (RBT) was adopted for years of assessment commencing on or after 1 January 2001 and Capital Gains Tax (CGT) was introduced with effect from 1 October 2001. According to the 2000 Budget Review a move to a residence-based system would significantly broaden the tax base, limit opportunities for tax arbitrage and bring the tax system in line with generally accepted international practice. The relaxation of exchange controls for South African residents with effect from 1 July 1997 made it possible for residents to invest limited funds offshore. The Fifth Interim Report of the Katz Commission suggested that if exchange controls were relaxed, the taxation of active income should remain on a source basis, but that passive income should be taxed on a residence basis. As a result deemed source rules in the form of section 9C and 9D were introduced into the Act with effect from 1 July 1997 and applied to “investment income” as defined. Section 9C taxed investment income of both residents and non-residents (from activities carried on by a permanent establishment in the Republic). Section 9D taxed investment income of controlled foreign entities and investment income arising from donations, settlements or other dispositions in the hands of residents. The taxation of foreign dividends with effect from 23 February 2000 as a first phase in the move to a residence based system, lead to the introduction of s 9E. Foreign Dividends were taxed in the hands of residents subject to certain exemptions. The basic interest exemption was extended to foreign dividends. Section 6quat was revised to extend the rebate to foreign dividends and profits of a company from which dividends were declared. Section 9D was amended to cater for foreign dividends received by or accrued to controlled foreign entities. The implementation of a full residence-based system of taxation with effect from years of assessment commencing on or after 1 January 2001 required amendments to various sections of the Income Tax Act as well as the introduction of new sections. A residence minus system was adopted which means that residents as defined are now taxed on their world- wide income with certain exemptions. Non-residents are taxed on their income from sources within or deemed to be within the Republic. The provisions relating to the taxation of foreign income of residents is complex; adding to the complexity is the fact that several changes have already been made to these provisions since the inception of the world-wide basis of taxation. The provisions must also be interpreted against the background of any double taxation agreement (DTA) between the Republic and the relevant foreign country as the applicable DTA may override the Republic domestic legislation. For purposes of this treatise the amending Acts enacted up to the end of December 2003 are taken into account. Hardly five years after the Katz commission of inquiry into the tax structure concluded that RBT and CGT were too complicated to be administered by SARS, the implementation of RBT and CGT were announced in the 2000 Budget. A detailed examination of the provisions relating to foreign income of residents as defined was undertaken. Interpretational issues to be clarified by legislation and certain planning issues are highlighted. It is essential to understand and carefully consider the Republic tax laws and the relevant double taxation agreements, for the successful application of the provisions. Careful planning before concluding transactions is of vital importance in order to avoid or minimize any unwanted tax consequences resulting from the RBT and CGT provisions.

A critical investigation into discourses that construct academic literacy at the Durban Institute of Technology

- Description: This thesis examines the construction of academic literacy at the Durban Institute of Technology through a discourse analysis of interviews with educators and learners. Academic literacy comprises the norms and values of higher education as manifested in discipline-specific practices. Students are expected to take on these practices, and the underlying epistemologies, without any overt instruction in, or critique of, these ways of being. Lecturer and student discourses are identified and discussed in terms of their impact on the teaching and learning process. This broad context of educator and student understandings is set against the backdrop of the changing educational policies and structures in post-Apartheid South Africa. The changes in approach to academic development are also traced as a setting for the institutional study. The discourses about the intersection between language and learning were found largely to assume that texts, be they lectures, books, assignments etc, are neutral and autonomous of their contexts. Difficulties some learners experience in accessing or producing the expected meaning of these texts were largely ascribed to their problems with language at a surface level rather than to their lack of shared norms regarding the construction of these texts. The study provides an analysis of how the ‘autonomous’ model is manifested iii and illustrates the limitations on curriculum change imposed by this understanding of how texts are constructed and interpreted. Discourses of motivation presume that students’ difficulties in taking on the literacy practices esteemed by the academy are related to attitude. This discourse assumes that learners have a fairly fixed identity, an assumption that did not bear out in the data. The multiple identities of the learners often presented tensions in the acquisition of discipline-specific academic literacies. The learners were found not to invest strongly in an academically literate identity, or were found to experience conflict between this target identity and the identities they brought with them to the institution. The elevation of academic literacy practices is questioned if the surface features, characteristic of these practices, are valued without a concomitant claim to knowledge production. The rapid emergence of a high skills discourse in Universities of Technology in South Africa is also interrogated, given the current emphasis on training for economic growth over discourses of social redress and transformation.

This discourse assumes that learners have a fairly fixed identity, an assumption that did not bear out in the data. The multiple identities of the learners often presented tensions in the acquisition of discipline-specific academic literacies. The learners were found not to invest strongly in an academically literate identity, or were found to experience conflict between this target identity and the identities they brought with them to the institution. The elevation of academic literacy practices is questioned if the surface features, characteristic of these practices, are valued without a concomitant claim to knowledge production. The rapid emergence of a high skills discourse in Universities of Technology in South Africa is also interrogated, given the current emphasis on training for economic growth over discourses of social redress and transformation.

- Description: Two of the post apartheid elections held in South Africa (1994, 1999) have been used as mechanisms to analyse and assess the extent to which the country’s transition from apartheid to a democratic dispensation is succeeding or not. The primary analytical focus of the 1994 and 1999 elections has revolved around the nature of the party system and voting behaviour. Basically, contestation has arisen over two primary and related issues: the dominance of the African National Congress (ANC) weighed against the weakness of opposition parties and the implications that this development has for effective democratic consolidation. Also, whether voting decisions based on divisive racial and ethnic identities that underlie electoral contests are pervasive enough to derail the process of democratisation. Generally, the primary conclusion has been that the unfolding pattern of South African electoral politics indicates sufficient grounds on which to doubt the prospects for effective democratic consolidation. This dissertation engages these debates with particular reference to the 2004 elections. In contrast to this pessimistic view of the prospects of successful democratisation in South Africa it upholds through an analysis of the 2004 elections the view that there is insufficient empirical evidence, to conclude that South Africa’s democratisation process is imperiled. It maintains that although there are problems related to the to the nature of the party system and some elements of voting behaviour there is enough countervailing evidence revealed by the 2004 election results that this does not present a substantially serious threat to the prospects of South Africa attaining a democratic society.

- Description: A new policy incorporating an operational protocol was developed for the establishment of new fisheries in South Africa. The common octopus, Octopus vulgaris was used as a candidate species for the project. The operational protocol consisted of a three-phased development framework, namely information gathering (Phase 0), an experimental fishery (Phase 1) and the final implementation of a commercial fishery (Phase 2). The present study focussed on phase 0 of this theoretical framework and protocol and was implemented by using a proposed octopus pot fishery in South Africa as a case study. Phase 0 included a desktop study, information gathering in the field, an economic feasibility study and the formulation of a Fishery Management Plan and experimental design for the fishery. Information gaps identified during the desktop study were addressed during field investigations into the population structure and biology of O. vulgaris along the southeast coast. Immature females were found to use the intertidal area to feed and grow before migrating to the subtidal area to mature and spawn. Mean size differed substantially between intertidal and subtidal areas, with larger octopus found subtidally. Age and growth trials using tetracycline as a marker showed that O. vulgaris deposit daily growth lines in their beaks. A genetic study showed that there is most likely only one panmitic population along the coast. The economic feasibility study indicated that a longline pot fishery could be feasible provided a 30% catch in 6600 pots/month is attained. Only existing, debt-free vessels should be used in this fishery. The Fishery Management Plan proposed in this study includes management measures such as effort limitation of licences and gear, size restrictions, vessel monitoring systems, and observer programmes. Based on the population dynamics and biology of O. vulgaris it is suggested that a precautionary approach to developing fisheries for this species in both the inter- and subtidal areas along the South African coast.

- Description: A new predictive modelling technique called the fuzzy envelope model (FEM) is introduced. The technique can be used to predict potential distributions of organisms using presence-only locality records and a set of environmental predictor variables. FEM uses fuzzy logic to classify a set of predictor variable maps based on the values associated with presence records and combines the results to produce a potential distribution map for a target species. This technique represents several refinements of the envelope approach used in the BIOCLIM modelling package. These refinements are related to the way in which FEMs deal with uncertainty, the way in which this uncertainty is represented in the resultant potential distribution maps, and the way that these maps can be interpreted and applied. To illustrate its potential use in biogeographical studies, FEM was applied to predicting the potential distribution of three invasive alien plant species (Lantana camara L., Ricinus communis L. and Solanum mauritianum Scop.), and three native cicada species (Capicada decora Germar, Platypleura deusta Thun. and P. capensis L.) in South Africa, Lesotho and Swaziland. These models were quantitatively compared with models produced by means of the algorithm used in the BIOCLIM modelling package, which is referred to as a crisp envelope model (the CEM design). The average performance of models of the FEM design was consistently higher than those of the CEM design. There were significant differences in model performance among species but there was no significant interaction between model design and species. The average maximum kappa value ranged from 0.70 to 0.90 for FEM design and from 0.57 to 0.89 for the CEM design, which can be described as 'good' to 'excellent' using published ranges of agreement for the kappa statistic. This technique can be used to predict species' potential distributions that could be used for identifying regions at risk from invasion by alien species. These predictions could also be used in conservation planning in the case of native species.

A geological evaluation of marine diamond placer deposits on the central Namibian inner shelf : a case study of the Hottentot Bay area

- Description: This study focusses on the marine diamond placers within Exclusive Prospecting Licence 1950 and Mining Licence 103a, located northwest of the north-facing Hottentot Bay which is 60 km north of Lüderitz, along the central Namibian coastline. The thesis follows the natural geological evolution of the marine placer deposit from primary source, through alluvial and/or glacial transportation, concentration along the coastline by wave, aeolian and alluvial/sheet-wash processes and finally marine diamond placer preservation. All of these processes are reviewed as they are important in understanding of the evolution marine placer deposits. The poly-cyclic role of coastal aeolian, alluvial, and marine processes, in marine placer enrichment is shown to be particularly important in considered target identification and prioritisation. A detailed bathymetric, sonographic and seismic interpretation, is an integral part of diamond placer exploration, and was used to examine and describe surficial and sub-bottom characteristics within the study area. Marine placers are formed along palaeo-strandlines during periods of marine transgression and regression and are therefore fundamental in marine placer exploration. A detailed bathymetry map, compiled for this study, of the area between Lüderitz Bay and Clara Hill, provides the foundation for a detailed terrace level investigation. Regionally, twelve well-developed stillstand levels are identified, nine of which fall into the study area. These interpretations are compared with global eustatic as well as terrace and resource/reserve levels in the Lüderitz area and are found to correlate well. Sediment dynamic studies involve the use of accredited application software for wave refraction modelling, to determine the wave angle and orbital wave velocity at the seabed. Bedload velocities, required to move diamonds of specific sizes, can be empirically determined and therefore areas of diamond entrainment and deposition can be modelled and target features delineated and prioritised. These detailed interpretations provide a sound platform for evaluating diamond placer process models in the study area. By integrating both previously published and newly formulated ideas, a revised, holistic model for the formation of marine diamond placer deposits in central Namibian is postulated. The proposed model is tested by comparing it to the lateral distribution of presently defined resource/reserve areas in the Lüderitz area and shows a close correlation with most of these enriched deposits. Based on this model, a matrix for the delineation and prioritisation of marine placer deposits is developed and the best target features within the study area are identified. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This study has investigated the interaction between honeybees and their forage plants and the impact of selected climatic variables on honey production in South Africa. Twenty-seven scale-hive records from 25 localities have been used as a measure of colony honey reserves. At least 944 plant species are visited by honeybees in South Africa for their nectar and/or pollen, with more than half providing both rewards. The entire honeybee flora encompasses 532 genera and 137 families. The flowering phenologies of the different reward categories of the indigenous forage plants are all significantly and positively correlated at the 0.05 level. Similarly, species offering both rewards are significantly and positively correlated with the flowering phenology of the null flora. The same results were obtained for correlations between the different reward categories of the exotic forage plants in South Africa. Of the 30 species pairs which fulfilled the criteria for selection, 23 occurred in sympatry, 5 in allopatry and 2 in possible parapatry. There is evidence for both competition and facilitation within different indigenous species pairs. The lack of geographical correlation in the intra-annual variation in honey stores and the near absence of any statistically significant (p < 0.05) honey related intra-annual intracolonial correlations may indicate that the former is more important than the latter for the determination of the level of honey reserves within a colony. Only one statistically significant correlation was found between either scale-hive record from the University of Pretoria Experimental Farm and any of the selected climatic variables. A one month lag period and/or possible seasonal effects were detected for each variable, with the exception of the duration of sunshine, in the autocorrelation analyses. A possible 12 month seasonal period was also identified in the single series fourier analyses for a number of variables. Similarly, 12 months was also the most frequently recurring period in the crossspectral results for the one scale-hive record (H42). Any activities which have an impact on the landscape have the potential to affect honeybees and/or their forage plants. Honeybee crop or plant pollination may also enhance yields for commercial farmers and facilitate rural food security.
