- Description: It has long been recognised that small and medium enterprises (SMEs) account for an overwhelming part of businesses worldwide and that they contribute considerably to private sector Gross Domestic Product (GDP), growth and are the source for most new employment opportunities. It may therefore be postulated that scaling and growing SMEs are of notable importance to the economic wealth of the country and to this extent it eliminates economic stagnation. This treatise argues the significant impact that entrepreneurship exerts on the South African economy. This would allow the role players to identify the strategic interventions necessary to grow and scale SMEs. A literature review was conducted to develop insights on the factors that affect the scalability of SMEs. The aforementioned section expounds on the concept of SMEs. Secondly, the emergence of SMEs across developed and emerging economies is discussed by exploring the United States of America, Europe and the BRICS economies respectively. Thirdly, SMEs in the South African context are explored. Fourthly, the requirements and challenges of SMEs in the South African economy are highlighted. The primary data for this study were collected from the sample by means of an online questionnaire and through fieldworkers who were deployed to collect responses from the sample group. A representative sample of n = 295 responses were received. Descriptive statistics were used to summarize the data in a way to simplify the interpretation of the data. Inferential statistics were used to authenticate conclusions made from the data. The model was developed and identified the following factors as exerting influence on the scalability of SMEs: Access to Finance, Access to Markets and Access to Human Capital, Entrepreneurial Intention, Regulatory Framework, Business Support and Networks. The average mean values of the factors were then used to establish their position or ranking as determined from the responses received. All factors ranked above a mean value of 3 which indicates that SMEs have a neutral to positive opinion of the factors identified in the model. According to a one-tailed t-test from the sample of SMEs it was shown that two of the nine factors had a large effect size in the factors of Human Capital and Entrepreneurial Intention. The Scalability of SMEs’ model developed in this study specified the factors that influence the growth of SMEs.

- Description: Over the years, the extent to which the legal framework of the World Trade Organisation (WTO) makes provision for environmental protection has been a major issue within the organisation. While trade liberalisation and environmental protection are fundamental objectives of the WTO to be pursued in line with the sustainable development goals as enshrined in the Preamble of the Marrakesh Agreement, the organisation does not have a specific agreement on the environment. Moreover, efforts by the member states of the WTO to reform the environmental protection regime of the global trading system have achieved little. Nevertheless, under the current legal framework of the WTO, members are allowed, subject to a number of conditions, to adopt trade-related measures aimed at protecting the environment. Employing documentary research methodology, this study critically evaluates the relationship between trade and the environment, the provisions made for environmental protection in selected WTO agreements and the extent to which trade-related environmental protection measures are permissible under the legal framework of the WTO. It also evaluates the implications of unilateral and the Multilateral Environmental Agreements (MEA)-based environmental trade measures as well as the possibility of a clash of policy objectives between the WTO Agreements and the MEAs, given that some of the MEAs contain environmental trade measures prohibited by the WTO free trade rules. The findings made in this study suggest that states generally prefer to enforce unilateral environmental trade measures against foreign goods. This has allowed states, in some instances, to hide under the guise of environmental protection to pursue protectionist’s interests, eco-imperialism, etc., leading to the trade and environment-related disputes at the WTO. Moreover, the WTO is made up of member states that are at different levels of development and possess different environmental protection standards. Hence, there is concern from developing countries, on the one hand, that their economic interests are being frustrated by the stringent application of unilateral environmental trade measures in the developed countries, and, on the other hand, that the environmental burden of international trade is being shifted to the developing countries as the developed countries tighten their environmental standards. The study concludes that the environmental protection regime of the WTO as it stands is not adequate to guarantee the balance of trade and environmental protection objectives as well as the balance of interests between the developed and developing countries. The study, therefore, recommends reform in the environmental protection regime of the WTO to ensure that the environmental protection measures are adequately provided for and that balance of interests between the developed and developing countries is maintained in order to ensure sustainable global trade. It further recommends that a mutually reinforcing relationship should be established between the WTO and the MEAs to avoid a possible clash of policy objectives.

- Description: To date, there has been little contemporary academic study on public art in Port Elizabeth. There have however been major art-led urban regeneration projects in the last ten years. This raises the question of what these artworks have been ‘doing’ in their relatively new homes. This study explores the function of the Voting Line, which was commissioned by the Mandela Bay Development Agency and made by Anthony Harris and Konrad Geel. The Voting Line is discussed as a key example of public artwork produced for Route 67. Using a case study design, four different approaches have been applied in this exploratory study. These include: document analysis, observation, interviews and a South African data making process called the Mmogo Method. The findings of this study suggest that the Voting Line is broadly considered as contributing towards nation building; cultural heritage tourism, and developing city identity.

- Description: The Cape Vulture (Gyps coprotheres), a southern African endemic, is a species currently listed on the IUCN Red List as “Threatened” due to its 66-81% decline over the past 50 years. South Africa and Lesotho hold 90% of the global population, which are focused at two core areas, namely northern central South Africa and eastern South Africa. This species provides important ecological services yet faces numerous anthropogenic threats. An emerging threat in the south eastern part of South Africa is that of wind energy development. Understanding the movement and roosting behaviour of the Cape Vulture may mitigate potential collisions if areas of high use are avoided. Juvenile Cape Vultures, who naturally suffer high mortality rates, are known to forage extensively over a wider landscape and as a consequence may face a greater assortment of threats. The overall aim of this study therefore was to determine the ranging and roosting behaviour of juvenile Cape Vultures in the Eastern Cape Province, South Africa. In order to achieve this aim, i) the ranging behaviour and habitat use were determined and ii) roost sites and factors that influence roost site selection were determined. Using five juvenile Cape Vultures tagged with Global Positioning System (GPS/GSM) transmitters, home range sizes, distance travelled from the nest and habitat use were determined. Home range was determined through kernel density estimates and distance travelled from the nest was determined through the Euclidean distance. Habitat use was determined by overlaying the home range size onto a merged layer of all protected areas and the National Land Cover Database of South Africa. To determine roost sites, data from the tagged vultures were split into encamped and exploratory movements using a mixture model in a cluster analysis setting. Encamped movements were associated with roost sites. Roost density was determined around the natal colony using predetermined buffer sizes and a generalised linear mixed model (GLMM) fitted to the data. Conditions considered favourable for roost sites were based on previous research conducted on cliff-nesting species and a GLMM conducted. Juveniles increased their home range progressively for the first two months, then exhibited a rapid increase in size associated with dispersal from the colony. Distance from the nest increased rapidly following the dispersal period. Protected areas and woody vegetation were areas of preferred habitat. The highest density of roosts for juveniles was located within 20 km’s from the breeding colony and decreased further away. Roost sites that were favoured for juveniles and adult birds were those that were located close to colonies, had low accessibility to terrestrial predators and were in areas of high wind speed. The orientation of the cliff into the prevailing wind direction was also a determining factor. Roosting sites and foraging areas are important spatial determinants of Cape Vulture behaviour and the identification of such areas can help with conservation management. With the additional threat of wind development in areas highly utilised, wind farms located too close to colonies could have a devastating impact on the Cape Vulture population. Therefore, this study highlights the importance of conservation buffer zones as no-go areas for wind energy development around vulture colonies.

- Description: Bonefish (Albula spp.) support valuable recreational and artisanal fisheries worldwide. Declining stocks have been reported at multiple localities, potentially jeopardising numerous multimillion-dollar industries. In particular, tourism generated through bonefish fly fishing contributes considerably to the economies of many isolated tropical islands and atolls. However, despite their economic value, little is known about bonefish in the Indian Ocean. This study aimed to contribute to the understanding of bonefish ecology in the Indian Ocean by (1) reviewing the bonefish literature to identify knowledge gaps; (2) evaluating the postrelease survival of acoustically tagged bonefish and; (3) quantifying the spatial and temporal movements of bonefish at a near-pristine and predator rich atoll in the Seychelles. A review of published literature on bonefish indicated that despite considerable biological and ecological research in the Pacific and Atlantic oceans, virtually no research has been conducted in the Indian Ocean. To help address this research gap, an acoustic telemetry study was initiated at the remote St. Joseph Atoll, within an existing array of 88 automated datalogging acoustic receivers. Thirty Albula glossodonta were surgically implanted with Vemco V13 acoustic transmitters in May 2015 and tracked for a period of one year. Only 10% of the tagged bonefish were detected for more than two weeks. A comparison of the final 100 hours of movement data from fish that were detected for less than two weeks to fish detected for longer periods revealed distinct differences. These included differences in area use patterns and significant differences in the average daily distance moved, speed of movement and residency index. This suggested that mortality in the form of post-release predation was high (90%) with tagged fish detected for less than two weeks being preyed upon by sharks. The three surviving bonefish were tracked for 210 to 367 days. These individuals remained in the atoll and showed high use of the marginal habitats between the shallow sand flats and the deeper lagoon. Water temperature, diel cycle and tide were significant predictors of bonefish presence in the lagoon. The high post-release predation of bonefish has implications for the management of this and other Albula species. Despite these fisheries being catch-and-release, bonefish fishing may be unsustainable due to the high post-release mortality, particularly in areas that are rich in predators. Therefore, protected areas or limitations on fishing effort need to be considered.

- Description: The study aimed at investigating the resilience enhancement factors which promoted well-being among divorced African women in Cradock, the Eastern Cape, South Africa. A qualitative research design was used to investigate the factors which reinforced resilience and promoted well-being following divorce as studies have indicated the risk of not being able to cope following divorce trauma. Purposive sampling was used in recruiting twelve divorced participants (aged 25- 45) from a support group at a local church in Cradock. Data was collected by means of semistructured interviews following the permission of the church and the divorced women who gave their consent to conduct the study. Furthermore, ethical principles were adhered to, throughout the data collection process. Thirteen themes emerged in the study and they include; self-condemnation, self-blame and denial, loneliness depression, anger and embarrassment, stigma, personality change, sexual dissatisfaction, ambivalence, forgiveness, selfcontentment and self-compassion, personal growth, religious coping, social support and positive relations and resilience enhancement factors. Despite the achievement of the research objectives, the sample might not be the true representation of the population of women who experienced divorce. Also, the results might have been different if the study was quantitative in nature. Based on the findings, psychological support is needed for women who underwent divorce. Finally, churches should play a vital role in restoration of resilience among divorced women while the families and communities shift away from cultural beliefs of subjugating women.

- Description: Construction plays an important role in South Africa’s socio-economic development. The Construction Industry Development Board (CIDB) was therefore developed in terms of the CIDB Act 38 0f 2000 and its reason for establishment is to lead the construction industry stakeholders in construction development. Some of the responsibilities of the CIDB is to ensure that there is skills development and transformation in the industry. On the delivery of infrastructure assets for the benefit of the ordinary citizens of South Africa, there are frequent challenges that contractors tend to experience. Such challenges include a wide range of compliance protocols such as tax compliance issues. The limited knowledge of taxation often result in understatement of income culminating in taxation audits and ultimately significant penalties and unexpected taxation liabilities. Other critical areas include successful project management of projects including proper costing and scheduling of project activities. The extent of this problem is evident in the number of terminations of contracts of such service providers, where some of them have even been blacklisted on the National Treasury Database of restricted service providers prohibiting them from doing any business with government for a stipulated period. The primary objective of the study was to investigate the factors that contribute to threatening the sustainability of black owned emerging construction companies. In order to gain an understanding of the problems that contractors face that pose a threat to their sustainability, questionnaires will be distributed to contractors and reviews by interview will be conducted. A qualitative study was therefore conducted. The relationships between the skills set of the contractors, the type of work they have for example, government and/or private sector work, methods of funding projects, periods of receiving payments, SARS compliance requirements and how these factors interrelate with each other was investigated. The causal effect/relationship of each of these on the sustainability of the contractors was determined. This study involves a case study approach and a qualitative research design. A multiple-case study method was selected to broaden the understanding of the phenomenon under of the study. The two black-owned construction companies used as the subjects for this study were selected on the basis that they would enable this research to determine what factors play a role and what threats are to their sustainability, in spite of the government support programs. The interpretivism approach was used as a means of describing what factors posed threats to the sustainability of emerging black construction companies. The aim of this study was not to test any hypothesis but to rather explore and gain an in-depth understanding of the construction industry, the role of the government and to understand what factors affect the emerging black construction companies to a point of point threats to their sustainability. The results of this study indicate that a wide range of challenges tend to hamper development and progress of emerging construction companies. Some of these challenges include poor employee retention strategies where very little emphasis is placed on the value of people. Workplace training through formal learnership or artisan programs are non-existent and a formalised role is required in this regard. Performance management is hardly measured or monitored in the business which has a direct impact on prospective growth. Cash flow is a critical challenge in the business and the study finds that financial management administrative skills are lacking. Financial management administration is linked to cash flow management and cash flow projections. The study also contributes to emerging theories such as business planning in relation to sustainable growth and innovation of SMEs.

The extent of this problem is evident in the number of terminations of contracts of such service providers, where some of them have even been blacklisted on the National Treasury Database of restricted service providers prohibiting them from doing any business with government for a stipulated period. The primary objective of the study was to investigate the factors that contribute to threatening the sustainability of black owned emerging construction companies. In order to gain an understanding of the problems that contractors face that pose a threat to their sustainability, questionnaires will be distributed to contractors and reviews by interview will be conducted. A qualitative study was therefore conducted. The relationships between the skills set of the contractors, the type of work they have for example, government and/or private sector work, methods of funding projects, periods of receiving payments, SARS compliance requirements and how these factors interrelate with each other was investigated. The causal effect/relationship of each of these on the sustainability of the contractors was determined. This study involves a case study approach and a qualitative research design. A multiple-case study method was selected to broaden the understanding of the phenomenon under of the study. The two black-owned construction companies used as the subjects for this study were selected on the basis that they would enable this research to determine what factors play a role and what threats are to their sustainability, in spite of the government support programs. The interpretivism approach was used as a means of describing what factors posed threats to the sustainability of emerging black construction companies. The aim of this study was not to test any hypothesis but to rather explore and gain an in-depth understanding of the construction industry, the role of the government and to understand what factors affect the emerging black construction companies to a point of point threats to their sustainability. The results of this study indicate that a wide range of challenges tend to hamper development and progress of emerging construction companies. Some of these challenges include poor employee retention strategies where very little emphasis is placed on the value of people. Workplace training through formal learnership or artisan programs are non-existent and a formalised role is required in this regard. Performance management is hardly measured or monitored in the business which has a direct impact on prospective growth. Cash flow is a critical challenge in the business and the study finds that financial management administrative skills are lacking. Financial management administration is linked to cash flow management and cash flow projections. The study also contributes to emerging theories such as business planning in relation to sustainable growth and innovation of SMEs.

- Description: The short lifetime of tyres causes great environmental harm due to their non-biodegradable nature resulting in land and water pollution. Exploration of novel uses for recycled tyres is therefore imperative. The use of recycled waste tyres as carbon source for the synthesis of fluorescent chemosensing carbon nanomaterial for the detection of harmful chemicals in water is proposed in this work. Three key problems are addressed in this study: i) re-using of waste tyre products, ii) synthesis of low-cost carbon nanomaterial, iii) detection of harmful compounds within environment systems. The fluorescent triazolyl-coumarin compound, 7-(diethylamino)-3-(4-(1-hydroxyethyl)-1H-1,2,3-triazol-1-yl)-2H-chromen-2-one, was synthesized in multiple steps from 4-diethylamino salicylaldehyde. The last step included the use of Cu(I)-catalyzed 1,3-dipolar azide-alkyne cycloaddition (“click-reaction”) to form a triazole ring. Carbon spheres were synthesized through catalytic chemical vapour deposition (CVD) from waste tyre pyrolysis oil (WTPO), as the carbon source, in the presence of a catalytic amount of ferrocene. The quality and quantity of the carbon spheres had an overall improvement as the synthesis temperatures increased from 800 oC to 950 oC. The diameter of the carbon spheres reduced from 1017 nm to 577 nm as seen in TEM and SEM imaging. TGA and XRD analysis indicated a direct relationship between an increase in synthesis temperatures with an increase in the crystallinity of the carbon spheres. Commercially available naphthenic oil was used as a reference to compare the impact of the starting carbon precursor on the morphology of the carbon nanomaterial under the same reaction conditions. Multi-walled carbon nanotubes were synthesized at the lower temperatures of 800-850 oC. Carbon fibres and carbon spheres were observed at the synthesis temperatures of 900-950 oC. The carbon source played a role in the morphology of the carbon nanomaterial as it could be seen between the complex natured WTPO and the pure naphthenic oil. The purified carbon spheres synthesized at 950 oC from WTPO were functionalized with the triazolyl-coumarin units on the surface through Steglich esterification using DCC/DMAP to yield fluorescent carbon spheres. Complexation studies of the functionalized carbon spheres were done using UV/Vis spectroscopy and fluorescence with a wide range of ions; Ag+, Al3+, Co2+, Cr3+, Cu2+, Fe3+, ii Hg2+, Li+, Ni2+, Pb2+ and Zn2+. The triazolyl-coumarin carbon spheres showed reasonable sensitivity and selectivity towards Fe3+ in water with a quenching effect in fluorescence. Titration studies with Fe3+ indicating an exponential decay of quenching in the fluorescence up to 68% with detection limit at 2.73 x 10-5 M.

- Description: Income tax in South Africa is levied in terms of the Income Tax Act, 58 of 1962 (the South African Income Tax Act) on taxable income, which by definition, is arrived at by deducting from ''gross income" receipts and accruals that are exempt from tax as well as deductions and allowances provided for in the Act. The South African Income Tax Act provides no guidance with regard to the taxation of income and expenditure from illegal activities. In this mini thesis, case law and legislation is reviewed in an attempt to provide clarity on the tax consequences of income and expenses arising from illegal activities. An overview is provided of the taxation of income and expenditure in respect of illegal activities in the United States of America, Australia and New Zealand. Similarities are found between the American, Australian, New Zealand and South African tax regimes in relation to the taxation of income earned from illegal activities, but there appears to be more certainty in America, Australia and New Zealand with regard to the deduction of expenses arising from illegal activities. In South Africa, taxpayers earning income from ongoing illegal activities will, in principle, comply with the definition of “trade” as defined in section 1 of the South African Income Tax Act. However, this is contrary to the view of the South African Revenue Service that illegal activities do not meet the definition of “trade”, a viewpoint that may not hold if challenged in court. Recommendations are made for the amendment of the South African Income Tax Act to specifically provide for the inclusion in “gross income” of income from illegal activities and to prohibit the deduction of expenditure arising from illegal activities.

- Description: Research asserts that learner performance in South African schools is in a state of crisis. While many more learners’ post-1994 in South Africa have physical access to education, very few have epistemological access. The quality of the education learners receive is polarised along socio economic lines. This crisis has its roots in the legacy of colonialism and apartheid, and as such, there is a need to transform the education system to ensure equal opportunity for all learners, and ultimately economic growth and security for the country. One of the explanations offered for the crisis in learner performance is the poor teacher education system. However, there is a paucity of research in teacher education generally in South Africa, and specifically in relation to pre-service teachers. Furthermore, little attention has been given to how initial teacher education could contribute to the promotion of a social justice agenda with the intention of transforming the South African schooling system. This research seeks to understand how the expectations, scaffolding and assessment of preservice teachers’ teaching practices can be utilised to promote social justice during the Teaching Practice (TP) component of initial teacher education. In answering the research question, I analyse data and literature to identify a set of key valued functionings of quality praxis that preservice teachers ought to be provided the capability to realise, at the level of achieved functioning. This is a qualitative case study located in the interpretive paradigm. The case under study is: quality teaching practices of pre-service teachers. This case is bound by context (initial teacher education in South Africa) and setting (the pre-service teacher in the classroom). Two South African Higher Education Institutions (HEIs) were selected through purposive sampling and their respective Teaching Practice (TP) documentation was analysed. Focus group interviews were conducted with five lecturers involved in TP at one of the HEIs. The theoretical framework of the study used to guide the analysis of the data was underpinned by a social justice perspective on quality education. Given that a social justice perspective does not have analytic tools, I view quality pre-service teachers’ teaching practices as praxis and utilise the capability approach as a mechanism for identification and description of valued functionings and capabilities that contribute to quality praxis. There are four significant findings in my research. Firstly, there is consistency with regards to the valued functionings and capabilities across the TP documentation of the two participating HEIs. In other words, the conceptions of a capable pre-service teacher are similar. Secondly, if social justice goals are to be realised, greater clarity of the valued functionings needs to be evident in the TP documentation. Thirdly, the valued functionings can be categorised into those that are foundational and those that promote a social justice agenda. Finally, in promoting a social justice agenda, there are functionings that ought to be valued by the HEIs that are seemingly not currently valued.

- Description: Water lettuce, Pistia stratiotes L. (Araceae), and red water fern, Azolla filiculoides Lam. (Azollaceae), are floating aquatic macrophytes that have become problematic invaders in numerous South African waterbodies. Two weevils, Neohydronomus affinis Hustache 1926 (Coleoptera: Curculionidae) and Stenopelmus rufinasus Gyllenhal 1936 (Coleoptera: Curculionidae), are successful biological control agents of these two species, respectively, in South Africa. However, nothing is known about the thermal physiology of these two species Therefore, the aim of this study was to investigate the thermal physiologies of these two species to explain their establishment, distribution and impact in the field. Laboratory based thermal physiology trials showed that both weevils were widely tolerant of cold and warm temperatures. The CTmin of N. affinis was determined to be 5.5 ± 0.312°C and the CTmax was 44 ± 0.697°C, while the CTmin of S. rufinasus was 5.4 ± 0.333°C and the CTmax was 44.5 ± 0.168°C. In addition, the lower lethal temperatures were -9.8 ± 0.053°C and -7.2 ± 0.19°C, and the upper lethal temperatures were 42.8 ± 0.053°C and 41.9 ± 0.19°C respectively. These results suggest that both species should not be limited by cold winter temperatures, as previously thought. This is evident in the field, where S. rufinasus has established widely on A. filiculoides, despite local cold climates in some areas of the plant’s distribution. Even though N. affinis has a similar thermal range, and should therefore theoretically reflect a similar distribution to S. rufinasus throughout South Africa, its distribution is limited by the range of its host, which is restricted to the warmer regions of the country, as is its biocontrol agent. Using the reduced major axis regression method, the development for N. affinis was described using the formulay=12.976x+435.24, while the development of S. rufinasus was described by y=13.6x+222.45. These results showed that S. rufinasus develops much faster, in fact almost twice as quickly, than N. affinis. Using these formulae and temperature data obtained from the South African Weather Service, N. affinis was predicted to complete between 4 and 9 generations per year in South Africa, while S. rufinasus was predicted to complete between 5 and 14 generations per year around the country. This study showed that although the native range of these two species is warm temperate to tropical, they possess sufficient thermal plasticity to not only establish, but also damage their respective host plants in far cooler climates. Thus, in South Africa N. affinis and S. rufinasus are limited by the distribution of their target weeds and not climate.

- Description: This study seeks to find out what the understanding and adoption of e-finance is by small and medium enterprises (SMEs). The study defines the concepts related to efinance namely, e-services and micro-finance and well as other related IT for development concepts. Firstly, the study identifies benefits of adoption and use of efinance as decreased transaction costs, increased access to financial information and increased access to financial products and services. Secondly the barriers to the adoption of e-finance are identified as poor privacy, security and safety; poor IT telecommunications infrastructure; uncertain IT regulatory and policy and low T training and skills. The results produced by the study confirm a high understanding of e-finance amongst SMEs and all benefits and barriers are confirmed except for one, decreased transaction costs. The study recommends that further research be conducted on this benefit as it may no longer be relevant, especially for developing countries. Limitations of the study include the relatively small sample size and snowballing sampling method used.

- Description: This study deals with the synthesis of silica particles, treatment of flax fabrics with silica, and the preparation and characterization of silica coated flax fibre reinforced phenolic composites treated with silica. Silica particles were successfully prepared by means of a hydrolytic sol-gel route. Two types of silica were prepared by employing either ammonium hydroxide solution as a base catalyst and acetic acid as an acid catalyst. The silica sols were then aged from three to five days in order to determine the effects of aging on the final properties of the silica. The chemical composition of the silica particles was evaluated by fourier transform infrared spectroscopy (FTIR), thermal stability was determined by using thermogravimetric analysis (TGA), and structural and physical properties of the silica particles prepared via two catalysts and aged at different time periods was investigated by x-ray diffraction (XRD). Silica sols, prepared at different conditions were then applied to treat flax fabrics (untreated/scoured) by use of the padding technique. The effects of the silica treatments on flax fabrics were evaluated by FTIR, XRD, determination of moisture content and mechanical properties. The FTIR revealed presence of silica groups on the silica treated flax fabrics, thus resulting in low moisture content for silica treated flax fabrics. XRD analysis revealed that aging the silica sols increases the crystallinity index. Silica treated flax fabrics showed enhanced tensile properties in the weft direction. The thermal, mechanical and water sorption properties of the composites were evaluated. TGA results revealed that the decomposition temperatures of the silica treated composites shifted to higher temperatures. Thus, silica treatments lead to an improvement in thermal stability for composites. A reduction in mechanical properties was also observed for silica treated composites and some composites showed a reduction in water absorption. It was quite evident from this study that the type of catalyst system used in silica preparation has a great influence on the final properties of the silica, which to a large extent changes the thermal, mechanical and water sorption properties of the composites.

- Description: This study deals with the synthesis of silica particles, treatment of flax fabrics with silica, and the preparation and characterization of silica coated flax fibre reinforced phenolic composites treated with silica. Silica particles were successfully prepared by means of a hydrolytic sol-gel route. Two types of silica were prepared by employing either ammonium hydroxide solution as a base catalyst and acetic acid as an acid catalyst. The silica sols were then aged from three to five days in order to determine the effects of aging on the final properties of the silica. The chemical composition of the silica particles was evaluated by fourier transform infrared spectroscopy (FTIR), thermal stability was determined by using thermogravimetric analysis (TGA), and structural and physical properties of the silica particles prepared via two catalysts and aged at different time periods was investigated by x-ray diffraction (XRD). Silica sols, prepared at different conditions were then applied to treat flax fabrics (untreated/scoured) by use of the padding technique. The effects of the silica treatments on flax fabrics were evaluated by FTIR, XRD, determination of moisture content and mechanical properties. The FTIR revealed presence of silica groups on the silica treated flax fabrics, thus resulting in low moisture content for silica treated flax fabrics. XRD analysis revealed that aging the silica sols increases the crystallinity index. Silica treated flax fabrics showed enhanced tensile properties in the weft direction. The thermal, mechanical and water sorption properties of the composites were evaluated. TGA results revealed that the decomposition temperatures of the silica treated composites shifted to higher temperatures. Thus, silica treatments lead to an improvement in thermal stability for composites. A reduction in mechanical properties was also observed for silica treated composites and some composites showed a reduction in water absorption. It was quite evident from this study that the type of catalyst system used in silica preparation has a great influence on the final properties of the silica, which to a large extent changes the thermal, mechanical and water sorption properties of the composites.

- Description: Disputes are part and parcel of human nature and always manifest everywhereincluding the employment arena. It is this inevitability of disputes that warrantsmeasures to be in place so as to effectively and without delay, resolve them in order to realise industrial peace. This study is prompted by the way industrial disputes have been handled in the past and the contemporary era. South African legal system provides Alternative Dispute Resolution (ADR) mechanisms to the use of adjudication by the ordinary courts in resolving workplace disputes. However, a set of methods made up of conciliation, mediation and arbitration have not been effective in resolving labour disputes owing to a variety of factors. Failure to provide a speedy resolution of disputes, large number of referrals to the Commissioner for Conciliation, Mediation and Arbitration (CCMA) and a large number of review applications lodged at the Labour Courts are some of the contributory factors that delay matters in bringing to finality. It is therefore the aim of this study, to proffer plausible recommendations that intends to cure and provide a silver bullet to the lacuna which exists in the current labour dispute system. To achieve the above stipulated aim, a general background of the study, accompanied by the chronicles of dispute resolution statutes and mechanisms is deliberated. Thereafter, South African compliance with International Labour Organisation (ILO) Conventions is discussed to assess the efficacy of labour dispute mechanisms. A critical analyses of the effectiveness of ADR within the scope of Labour Relations Act (LRA) 66 of 1995 will then follow. Although there are some limitations to this study, it should be noted that relevant legislation passed by parliament, cases, together with international and regional conventions ratified by the government, scholarly articles, journals and books are used to strengthen arguments and provide guidance in achieving the aims and objectives of the study.

- Description: Within the design studio at the Department of Architecture, Nelson Mandela University, the timeous submission of design projects is a problem. After close inspection, it is noted that students spend weeks on conceptual design ideas with no progressions towards completion. The purpose of the study is thus to determine whether building information modelling (BIM), as opposed to the traditional method of design, can be used to improve informed design communication during conceptual design for the first-year master of architecture students and contribute to timeous design project submission. A cohort comparison rubric will be used as the method for looking at the qualitative attributes of design intention, function, aesthetics, and sustainability. The 2016 cohort made use of the traditional design method, whereas for the 2017 cohort the BIM course was introduced in the computer module with implementation in the design studio. The work of nine students from both cohorts was analysed and findings include the following: improved drawing type availability, accuracy, and quality; reduced time spent on redundant work; inclusive discussions compared to isolated critique sessions; reduced printing costs - and the establishment of “what if” scenarios early in the project. Based upon the research findings it can be concluded that BIM as a teaching strategy and process has the capability of improving the communication between student and lecturer in the conceptual stage, thereby leading to a more timeous submission. It is recommended that BIM education must be incorporated in the undergraduate programme thereby providing students with an appropriate platform for expressing conceptual ideas more effectively within the design course.

- Description: The study seeks to explore the use of electronic information resource in the University of Fort Hare (UFH) Library. The objectives of the study are to determine factors that influence acquisitions of electronic information resources at UFH library, to find out the user’s responses to electronic information resources in the library and identify the challenges faced by UFH library regarding the usage of electronic information resources. The literature review was conducted through an acquisition of electronic information resources in academic libraries, collection development policies of academic libraries in South Africa and application of electronic information resources within South Africa and globally. The study is based on Diffusion of innovation (DOI) theory. The study adopted qualitative and quantitative approaches, and the non-probability sampling-Quota sampling was used for students and purposive sampling technique for librarians and academics. The data was collected with self-administered questionnaires and document analysis. The study found that academics were not fully involved in the acquisition of the library electronic information resources; therefore, there is a lack of communication about the acquisition of electronic resources. The study further reveals that there is usage of electronic information resources; however, there are library users who prefers to use search engines such as google, yahoo etc. It was also identified that there are two important barriers that hinder the use of electronic information resources, i.e. physical and personal barriers. The study recommends that University of Fort Hare library should consider including e resources in the collection development policy. It is also recommended that the library online training/tutorials must be installed on the library website to increase the usage of e-resources. In order to stay relevant and visible, librarians should embrace new opportunities and go beyond the comfort zone of traditional librarian principles.

- Description: This study provides an investigation into the current transition socio-culturally concerned photographers are making from traditional two-dimensional flat imagery, towards three-dimensional materiality based photographic installation artworks. According to Dr. Gillian Rose (2016), larger society is found to be in a state of oculacentrism, where vision and visuals are central to contemporary every day experience, resulting in the medium of photographic expression not being used and experienced by the average person as an art medium at all. So much so that these traditional photographic forms of visual communications have found a decline in visual engagement and subsequently visual impact. In an attempt to combat this change in the relationship between photographic imagery and audiences, select socio-cultural photographers are adopting practices incorporating three-dimensional, immersive installation techniques (Shore, 2014: 7-11), (Lister, 2007: 272). The aim is to provide a three-dimensional installation space, where the audience is encouraged to engage with socio-cultural issues. The study focuses specifically on two sociocultural photographers, Damien Schumann and Angelica Dass, who have communicated socio-cultural stories in this three-dimensional photographic installation space. In order to analyse and derive valuable techniques and approaches from their selected works The Shack (2010) and Humanae (2017) the study combines sections of Dr. Gillian Rose’s Visual Methodologies Framework (2016) as well as installation analysis tools designed by author Mark Rosenthal (2003). The same analytical criteria are then applied to the practical components socio-cultural topic communicating the Stigmatism Towards Persons With Albinism in Sub-Saharan Africa. The study concludes having created a three-dimensional photographic installation exhibition using similar techniques identified within the selected artists, moving beyond twodimensional forms to present a combination of three-dimensional techniques for enhanced socio-cultural visual communications.

- Description: The study sought to investigate the use of RFID technology as inventory control in academic libraries in South Africa, with a focus on the University of South Africa and the University of Fort Hare libraries. The objectives of the study were to describe the current inventory control practices at the libraries of the University of South Africa and the University of Fort Hare in order to determine the infrastructure required for the use of RFID for inventory control for the University of Fort Hare’s libraries; to evaluate the benefits of RFID technologies, in order to gain a competitive advantage for the University of South Africa’s and the University of Fort Hare’s libraries; to identify the challenges associated with adopting RFID technology, as experienced by the libraries of the University of South Africa and the University of Fort Hare. The study adopted both the quantitative and qualitative research approaches. The researcher followed a rigorous methodological path that began with a thorough literature review coupled with the careful and thoughtful posing of research questions and objectives. A purposive sample of forty (40) respondents was selected from the library staff from both the University of South Africa and University of Fort Harelibraries. The collected data were analysed using the Statistical Package for Social Sciences 23 (SPSS 23) and Microsoft Excel 2010. The findings of the study revealed reasons for both academic libraries to invest in RFID technology; these reasons include RFID’s ability to deliver self-service options, inventory control, improved reader access and improved security. The challenges related to the implementation of RFID technology are also related to staff not being rewarded by library management for being innovative; the difficulty of staff learning new technology; the staff’s inability to generate new ideas for the library; and the staff not being able to share knowledge with each other. Further research needs to be conducted by library RFID vendors in order to meet the need, of academic libraries, for RFID inventory control. RFID hardware and software (API software) should be subjected to further investigation for the purposes of research and development. Libraries should work closer with RFID vendors so as to trial and test hardware and software.

- Description: Mathematics is the foundation for the economic and technological development of any nation. It has been asserted that Mathematics is expected to help in accelerating social, economic and technological progress of any society. The Primary school level is very important in any educational system and any lack at this level would permeate to other levels of the educational system. Hence, this dissertation examines the use of textbooks by teachers in teaching Mathematics at selected primary schools in East London Education district. The study adopted the interpretivist paradigm and employed the qualitative approach in investigating the phenomenon. The dissertation made use of phenomenology research design as it attempted to understand people’s (learners’ and teachers’) perceptions, perspectives and understandings of the use of textbooks in teaching Mathematics. Semi-structured interviews and observation were used to elicit information from the six mathematics teachers and three heads of department who were purposively selected. The data collected were analysed using thematic approach where themes were developed from the research questions after transcribing, sorting and categorizing them. The findings of the study demonstrated that the participants selected textbooks from the ones prescribed by the department that were written in the CAPS documents. They had no influence or decision on textbook selection. All the teachers believed that lesson plan is very important and it is a must to have a very detailed and comprehensive lesson plan that is well-aligned to the contents of CAPS document and the textbook. The study further revealed that, for effective delivery of lesson and planning, there is need for a practical use of textbooks by the teacher. The study concluded that one of the most fundamental issues to consider is the fact that, as good as the use of textbook for planning and delivery of lesson activities is, it can also be a problem if not carefully and professionally planned and used accordingly. The over-dependence on textbooks at the expense of other resources may cause ineffective learning and teaching of mathematics.
