- Description: National Dairy Equipment (Pty) Ltd (NDE) is a privately owned stockist and distributor of stainless steel products and is a respected player in the South African stainless steel industry. NDE operates from within all four major cities in South Africa namely, Johannesburg, Cape Town, Port Elizabeth, and Durban. The organisation, with its wide range of corrosion resistant products, serves industries such as the architecture and construction, automotive, catering, and food and beverage industry. With the stainless steel industry growing in terms of the number of competitors, NDE performs a number of functions in order to achieve customer satisfaction. The general purpose of the study was to indentify the attributes that would act as drivers of customer satisfaction at NDE. Five attributes were identified namely, Service quality, Trust and commitment, Product quality, Commercial aspects and Reliability. The results of this study could assist managers at NDE in improving service delivery to customers. The literature study provided an overview of overall customer satisfaction and possible measurement models for customer satisfaction. Measurement models included, SERVQUAL, SERVPERF, the Two-factor theory, the Kano model and the Three-factor model. The latter proved to be of particular importance to the study as the model was used to classify the identified drivers into basic, performance and excitement factors. Furthermore, a literature review was provided based on each of the identified potential drivers of customer satisfaction. The empirical data needed to complete the study was collected by means of a survey, using a self-administered questionnaire. The questionnaire was distributed by sales representatives at NDE. A total of 320 useable questionnaires were received. The study revealed the following: each of the five proposed attributes had a positive relationship with overall customer satisfaction,thus all five attributes were confirmed as drivers of customer satisfaction at NDE. Commercial aspects and Reliability were classified as basic satisfiers. Trust and commitment was classified as a performance satisfier, and Service quality was identified as the only excitement satisfier. Product quality did not receive any classification. All importance mean scores were higher than the corresponding satisfaction mean scores. This study contributed to the existing body of literature and is seemingly the first of its kind in the South African stainless steel industry. The study is also the first to attempt the measurement of overall customer satisfaction levels at NDE. The methodology used in the current study can be applied to stainless steel industries internationally, in order to verify whether the confirmed drivers would also act as drivers of satisfaction in a similar industry elsewhere in the world.

- Description: Ephemeral wetlands provide numerous ecosystem services, but are disappearing due to urbanisation and habitat fragmentation. Knowledge is required to conserve these systems, but ephemeral wetland research in South Africa is lacking. As primary producers, microalgae provide a key link between the biotic and abiotic components of aquatic ecosystems. Despite their importance, there is a paucity in information concerning microalgal dynamics in ephemeral wetlands. The aim of this study was to understand the spatial and temporal dynamics of microalgae in ephemeral wetlands of the Nelson Mandela Bay Metropole. The research followed a funnel-based approach that assessed 35 wetlands at a regional level, followed by a temporal assessment of six wetlands, monitored biweekly, monthly or quarterly. Thereafter, a case study at local scale was carried out to address wetland connectivity and Hydrogeomorphic unit trends. The research culminated in a benthic flux chamber experiment, addressing the influence of microalgal-mediated processes on wetland development for a month post inundation. Phytoplankton biomass showed strong regional associations with rainfall zone, with Chl a concentrations of 17; 4.6; and 25 µg.L-1 in the high, intermediate and low rainfall zones, respectively. The MPB communities in Seeps, Depressions and Wetland flats, comprised between 45 and 60 % diatoms, whilst other microalgal groups were dominant in the water columns (> 90 %). Phytoplankton and MPB interactions facilitated significant night-time NH4+ and SRP effluxes, (1.5 and 0.4 mg.m-2.h-1, respectively) four days post inundation. High Silica uptake in the latter stages, was attributed to an increase in diatom abundance. Within the chambers, MPB growth was continuous whilst phytoplankton exhibited cyclical growth as the system approached dynamic equilibrium. This study demonstrated the importance of nutrient cycling in structuring aquatic food webs, and indicated the sensitivity of ephemeral wetlands to environmental perturbations.

- Description: Hard substrates in the marine environment are an important ecosystem of great scientific and economic value. Hard substrates provide suitable habitat for a diverse assemblage of benthic organisms. This thesis investigated the ecology of benthic hard substrate communities along a section of wave-exposed coastline, including the Sardinia Bay Marine Protected Area (MPA), in the warm-temperate Agulhas bioregion of South Africa. The effect of physical variables on benthic communities, including both the intertidal and shallow subtidal, was quantitatively assessed across (Chapter 3) and along (Chapter 4) the shore to provide a model of zonation for this bioregion and a baseline of community patters and biodiversity, as this information was lacking especially for the Sardinia Bay MPA. The zones described in Chapter 3 were in agreement with previous trends described for this bioregion with the addition of different biotopes in the upper Balanoid and deeper subtidal zones as well as the addition of an intermediate/transition zone in the subtidal between the algal dominated shallow subtidal and deeper subtidal, which has an increased abundance of sessile invertebrates. Disturbance is an important process in structuring benthic communities, and its role in structuring shallow benthic communities was investigated using a disturbance simulation experiment across a wave-exposure gradient (Chapter 5). Communities were found to change along the exposure gradient and monitoring the undisturbed communities showed that large waves caused disturbances across all the exposures. The recovery process was similar across all exposures mainly through lateral vegetative growth and regrowth from basal parts with communities in disturbed quadrats recovering to resemble the surrounding undisturbed community. Recruitment did not have a significant effect in the recovery process and community composition was therefore a result of the effects of the physical environment along the exposure gradient. Lastly this thesis investigated the indirect effects of protection in the small Sardinia Bay MPA (Chapter 6). Despite the small size of the MPA this study found differences in diversity and abundance between communities inside and outside the MPA. These differences in benthic biota infer indirect effects of protection that are probably due to the increase in abundance of exploited fish inside the MPA. Lower abundances of red algae, macroinvertebrates and diversity inside the MPA in the shallow depth category was attributed to the higher abundance of the generalist fish species that concentrate in the shallows. Significantly lower abundances of Chordata in the shallow and medium depth categories inside the MPA was attributed to predation by the benthic carnivorous species as ascidians are included in the diet of these species. This chapter also compared the effectiveness of destructive (scraped quadrats) and non-destructive (visually assessed quadrats) sampling methods. Scraped quadrats were found to be more effective in detecting changes across the MPA compared to visually assessed quadrats. Destructive methods sample the entire assemblage, to a higher taxonomic level, and measure abundance using biomass. It was concluded that biomass is a better metric when comparing communities across protection or other treatments as it provides better biological information of the community.

- Description: It is widely believed that Acacia karroo Hayne trees compete with and negatively affect the production of grasses in their immediate surroundings. This perception formed as a result of observations by farmers of their veld as well as some research. The complexity of plant interactions in different conditions required that research be done to better explain the extent of grass and tree interactions. In response to this need, the effect of a range of Acacia karroo densities on grass production was tested in areas of differing rainfall. Results emphasize the complexity of such plant interactions but highlight rainfall as influencing the effect of tree density on grass production and grass quality. Study sites were chosen with significant differences in tree density and rainfall and this was found to be concomitant with significant differences in grass yield and crude protein (p < 0.001). Grass yield (mass produced) was negatively correlated with tree density (p < 0.001) and was affected by rainfall. High tree density reduced grass yield at the lower rainfall sites, but a reduction in yield was only recorded during dry conditions in the higher rainfall areas. By contrast, the crude protein content of grasses was positively correlated to tree density (p < 0.001). However, as with yield, rainfall played an important part in the strength of the correlation. Soil properties such as temperature (-) (p = 0.011), phosphorus content (+) (p = 0.006), calcium concentration (+) (p = 0.005), acid saturation (-) (p = 0.018), and soil pH (+) (p = 0.008) were also significantly correlated to tree density. Tree density enriched the soil, subsequently benefitting grass quality. The study sites investigated, had different plant communities and environmental conditions with Cradock, Kubusi Drift and Kei Mouth having unique communities and conditions while Adelaide and Cathcart could not be separated in either. Cradock was the driest site and the vegetation was dominated by both grasses and karroid shrubs, differing in pattern and process from the other sites. The Kubusi Drift site had high tree densities, to the extent that the trees altered the grass species composition. The effects of rainfall on grass yield and quality exceeded that of community composition differences.

- Description: This study is about a population of 235 households in Blouberg municipality, Limpopo Province, that constituted itself in 2004 into a Communal Property Association. The Tale Ga-Morudu CPA was formed in order to own, manage and control a total of seventeen farms which were progressively restituted to them during 2004 by the Commission on Restitution of Land Rights. Tale Ga-Morudu households were dispossessed and forcefully removed from a number of fertile, arable and irrigable farms1in the 1960s due to racially discriminatory laws or practices. These households were then relocated by the then apartheid regime on the eastern part of Mogalakwena River. They were distributed in the arid communal areas of Laanglagte/Vergelegen, Matekereng; Ga- Mankgodi; Letswatla and Mamoleka under the traditional leadership of Kgoshi Maleboho of BabinaTšhwene. (Map one). It is the aim of this study to find out how Tale Ga-Morudu CPA currently uses these restituted farms for the households who have said to have benefited from restituted land. The researcher used his own observations, lessons and analysis of perspectives from case studies conducted from Limpopo in order to pursue this aim. This study adopted a descriptive household survey design that used a predominantly quantitative approach, and the use of qualitative methods to complement contextual details. A quantitative questionnaire was used on a sample unit of (20%) 45 households obtained by simple random sampling from a population of 235 households of the CPA. Other qualitative methods include focus group discussion, document review and observation. From the results it is clear that land claimants, prefer to retain existing practices of land use, than risk changes in land use in order to meet their socio-economic needs. Thus, instead of investing in commercial agriculture or wildlife farming, people follow subsistence agriculture and remain dependent on social grants and pensions for their livelihood. The general study findings show that the CPA planned to implement different types of land use including those of direct land use value. These include food gardens, resettlement; game farming; poultry enterprises and livestock grazing, and also of indirect use value. The latter refers to contract crop cultivation, rentals and strategic partnerships. The study found that despite income being generated from indirect types of land use, the majority of these intended beneficiaries never benefited from accrued financial dividends of land rental and development. However, households were still able to take advantage of employment opportunities created by contract crop cultivation and in the process they acquired crop cultivation skills. Furthermore the harvesting of natural resources such as wood and poles also contribute to the wellness of households. Households, also derived cultural wellness and a sense of satisfaction by accessing their restored farms to perform rituals. The general conclusion of the study is that the CPA is underutilizing its properties, including arable and irrigable fields, rentable recreational facilities, game farming and its tourism potential.

- Description: South Africa is a country with 11 official languages including English. English, however, dominates the educational sector, as medium of instruction. This is despite a plethora of research that shows the cognitive advantages of mother tongue instruction and language policies that promote additive bilingual approaches. As subtractive language approaches characterise poor schooling contexts, the outcomes for students are poor. This is because they do not develop proficiency in any language. The abolition of apartheid in South Africa and the advent of democracy in 1994 resulted in dramatic changes in the education system. Nevertheless, the medium of instruction from Grade four has remained English. Consequently, for the majority of the population the education is in their second language. This study takes place in the higher education setting of a TVET college, namely the Dower Campus in Port Elizabeth. It focuses specifically on Level 2 (first year) Life Orientation students to consider the effect English has, as medium of instruction, on the academic performance of students. There is concern about the status of TVET colleges. Even though the higher education sector has transformed, these skills based colleges are still given inferior status in the eyes of the general public and students themselves. These students may be particularly at risk of success given that they have lower entry requirements than other students in the higher education sector. The subject Life Orientation was used to examine the effect of English on student performance. Life Orientation has come under scrutiny for its usefulness and it cognitive value. This study argues that it is a valuable subject for students at colleges, equipping them with knowledge to succeed at studies and in society at large. However, the pass rates for Life Orientation have been consistently low. The study wanted to probe the role of English in this performance. To address the aims and objectives of this study, relevant literature and various multilingual approaches were reviewed to determine which strategies might be most effective in helping students cope with English as medium of instruction. The study also presents a case for the development of indigenous languages as medium of instruction. The study used a mixed methods approach, that is both qualitative and quantitative methods, to explore the use, attitude and perceptions of English among lecturers and students. The research used an interpretive approach and the study took the form of a case study. The researcher took the stance of being a non-participant observer. Qualitative data was obtained through the use of interviews while quantitative data was obtained through the use of questionnaires. The interviews were recorded and transcribed by a transcriber. Data was analysed using a thematic approach. The results showed that majority of the students did not speak English frequently nor had it as a home language yet they all had a positive regard for the language. Many factors were responsible for student performance in Life Orientation such as attitude to subject, theoretical versus practical components of the subject and student background. However, the medium of instruction played a large role in this performance. Though lecturers foregrounded the importance of English as medium of instruction, they recognise that it was a barrier to understanding and affected student performance. Analysis of the lecturer interviews and the questionnaires with students revealed that students were experiencing difficulty speaking, reading and writing in English. Lecturers adapted their teaching strategies when teaching by including translanguaging strategies of code-switching to facilitate understanding. The data also indicated that code switching was considered by the lecturers to be the most suitable method in teaching to student. Code-meshing and written translations of material were not strategies employed by lecturers. Students indicated that they would prefer to write assignments drafts initially in mother tongue. The findings also suggested that it was necessary for the lecturer to use a variety of multilingual strategies to ensure that students enjoy success in Life Orientation. Based on the findings, this study makes recommendations regarding the teaching and learning of English to students which includes the use of multilingual classroom strategies, collaboration with language lecturers and development of a multilingual language policy to aid in the understanding and acquisition of English terminology used in LO content. Such a language policy should also seek to develop indigenous languages as mediums of instructions at the college.

- Description: South Africa is a country with 11 official languages including English. English, however, dominates the educational sector, as medium of instruction. This is despite a plethora of research that shows the cognitive advantages of mother tongue instruction and language policies that promote additive bilingual approaches. As subtractive language approaches characterise poor schooling contexts, the outcomes for students are poor. This is because they do not develop proficiency in any language. The abolition of apartheid in South Africa and the advent of democracy in 1994 resulted in dramatic changes in the education system. Nevertheless, the medium of instruction from Grade four has remained English. Consequently, for the majority of the population the education is in their second language. This study takes place in the higher education setting of a TVET college, namely the Dower Campus in Port Elizabeth. It focuses specifically on Level 2 (first year) Life Orientation students to consider the effect English has, as medium of instruction, on the academic performance of students. There is concern about the status of TVET colleges. Even though the higher education sector has transformed, these skills based colleges are still given inferior status in the eyes of the general public and students themselves. These students may be particularly at risk of success given that they have lower entry requirements than other students in the higher education sector. The subject Life Orientation was used to examine the effect of English on student performance. Life Orientation has come under scrutiny for its usefulness and it cognitive value. This study argues that it is a valuable subject for students at colleges, equipping them with knowledge to succeed at studies and in society at large. However, the pass rates for Life Orientation have been consistently low. The study wanted to probe the role of English in this performance. To address the aims and objectives of this study, relevant literature and various multilingual approaches were reviewed to determine which strategies might be most effective in helping students cope with English as medium of instruction. The study also presents a case for the development of indigenous languages as medium of instruction. The study used a mixed methods approach, that is both qualitative and quantitative methods, to explore the use, attitude and perceptions of English among lecturers and students. The research used an interpretive approach and the study took the form of a case study. The researcher took the stance of being a non-participant observer. Qualitative data was obtained through the use of interviews while quantitative data was obtained through the use of questionnaires. The interviews were recorded and transcribed by a transcriber. Data was analysed using a thematic approach. The results showed that majority of the students did not speak English frequently nor had it as a home language yet they all had a positive regard for the language. Many factors were responsible for student performance in Life Orientation such as attitude to subject, theoretical versus practical components of the subject and student background. However, the medium of instruction played a large role in this performance. Though lecturers foregrounded the importance of English as medium of instruction, they recognise that it was a barrier to understanding and affected student performance. Analysis of the lecturer interviews and the questionnaires with students revealed that students were experiencing difficulty speaking, reading and writing in English. Lecturers adapted their teaching strategies when teaching by including translanguaging strategies of code-switching to facilitate understanding. The data also indicated that code switching was considered by the lecturers to be the most suitable method in teaching to student. Code-meshing and written translations of material were not strategies employed by lecturers. Students indicated that they would prefer to write assignments drafts initially in mother tongue. The findings also suggested that it was necessary for the lecturer to use a variety of multilingual strategies to ensure that students enjoy success in Life Orientation. Based on the findings, this study makes recommendations regarding the teaching and learning of English to students which includes the use of multilingual classroom strategies, collaboration with language lecturers and development of a multilingual language policy to aid in the understanding and acquisition of English terminology used in LO content. Such a language policy should also seek to develop indigenous languages as mediums of instructions at the college.

- Description: The effect of FDI on economic growth is not a straight jacket. Literature has shown that the effect of FDI on economic growth can be either positive or negative. The positive effects of FDI can be caused by increase in output stimulated by new technological innovations and increase in capital flows. The negative effects could result in a ‘crowding out’ effect on domestic investments, external vulnerability and dependence, destructive competition of foreign affiliates with domestic firms, and market stealing effect due to poor absorptive capacity.This treatise will attempt to shed light on the effect foreign direct investment has on economic growth in South Africa in order to ascertain whether a positive or negative relationship exists between these two variables. This study thus aims to investigate, analyse and estimate the extent to which FDI impacts economic growth in South Africa. The findings of this research will provide policymakers, commercial businesses and scholars with relevant updated theoretical and empirical results that will assist relevant government policy makers in generating effective measures of attracting FDI if it proves to be beneficial for the host country. If the results of the study prove that FDIs do not generate positive spill over effects then the policymakers are thus obliged to formulate policies that will discourage FDIs from penetrating the host country’s economy.

- Description: The prevalence of health risk behaviours is growing among South African employees. The deteriorating health of the public and the costs there off, which arise from making unhealthy choices about one’s lifestyle, are a major cause of many preventable Non-Communicable Diseases (NCD’s). The effect of these NCD’s on an organisation can result in employees’ ill health and negative stress, which in turn can lead to absenteeism, presenteeism and thus decreased productivity. Several studies propose that the absenteeism together with presenteeism can cost an organisation up to three times as much as medical costs with stress also being flagged as a severe work-related hazard. Literature shows that ill health affects employee ability to function optimally, thus indirectly affects productivity. Studies on on-site wellness programs, although they report savings in health care costs and increase in productivity, their true effectiveness is not sufficiently measured. To add to this, there is a paucity of work that exists regarding the benefits of on-site wellness programs in South Africa. It is suggested that data about the effect of successful wellness programs does not always make its way to academic literature, thus the observed shortage in investment on such programs from South African companies. This study we aim to find out the effect of on-site wellness programs on absenteeism, presenteeism, stress and health care costs. The results oppose what literature findings report. Reasons for these findings are therefore speculated.

- Description: Iron Fischer-Tropsch (FT) catalysts are typically prepared as iron oxides which are reduced to FT-active iron metal and iron carbide prior to FT synthesis. The iron oxides contain a variety of different chemical and structural promoters to alter FT-activity. Silica is a common structural promoter which stabilises the formation of small crystallites and provides mechanical integrity to the catalyst. However, silica inhibits the reduction of the oxide precursor to the FT-active phases. This ultimately affects catalyst activity and product selectivity. It has been proposed that the silica interacts with the iron to form encapsulating shells of fayalite (Fe2SiO4), or fayalite rafts between the iron oxide and the silica support. In this study, six silica-promoted iron oxide samples were prepared using a simple co-precipitation technique. Samples contain varying amounts of silica, and the samples are named 100/x Fe/SiO2, where x is the weight of silica for 100 weight iron, with x taking on values of 0, 10, 25, 50, 100 and 200. The resulting iron oxides were characterised using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRPD), M¨ossbauer spectroscopy (MS), magnetic susceptibility measurements (MM), Raman spectroscopy, thermal gravimetric analysis (TGA) and nitrogen physisorption. Their reduction in a hydrogen atmosphere was investigated using temperature programmed reduction (TPR), in situ XRPD and TEM. The reduction in hydrogen of 100/0 Fe/SiO2 and 100/10 Fe/SiO2 was also studied using in situ gas flow TEM cells. These cells allow the samples to be studied in the electron microscope at temperature and pressure conditions approaching those experienced in a real reactor environment. In the absence of a silica promoter (100/0 Fe/SiO2), hematite particles are formed with mean particle diameters of 39 ± 12 and 52.7 ± 0.2 nm determined using TEM and XRPD respectively. MM data reveals a magnetic transition (Morin transition) at≈230 K, consistent with a mean particle size of≈50 nm. In a hydrogen atmosphere, the hematite reduces to metallic iron via a two-step process viz. hematite → magnetite → iron. The final iron particles have an average crystallite size of 68.0 ± 0.2 nm. The presence of lower amounts of silica in the samples 100/10 Fe/SiO2, 100/25 Fe/SiO2 and 100/50 Fe/SiO2 results in the formation of silicasubstituted 2-line ferrihydrite particles. Bands in the Raman spectra of these samples shift on increasing silica content, which indicates an increasing number of Fe-O-Si bonds within the ferrihydrite framework. MM reveals typical superparamagnetic (SPM) behaviour above a blocking temperature in the range 39 - 68 K which gives mean particle sizes of 4.2, 3.6 and 3.5 nm for 100/10 Fe/SiO2, 100/25 Fe/SiO2 and 100/50 Fe/SiO2 respectively, in good agreement with particle sizes determined using TEM (3.1±0.4, 2.4±0.3 and 2.4±0.3 nm respectively). MS data at 300 K and 4.2 K were fitted with distributions of ∆EQ and Bhf respectively. The median values of Bhf decrease with increasing silica content, indicating greater degrees of distortion in the Fe3+ environments induced by increased silica substitution. The reduction to metallic iron occurs via a three-step process viz. hematite → magnetite → wu¨stite → iron, with the silica stabilising the wu¨stite phase. The increasing amount of Fe-O-Si bonds on increasing silica content shifts reduction to higher temperatures broadens each reduction step as a result of local Fe-O-Si concentration variations. Fractions of each sample are not completely reduced even at 1000°C, with the relative proportion increasing with increasing silica content. In situ gas flow TEM studies reveal that the mechanism of reduction involves the liberation of atomic iron atoms from the silica-substituted iron oxides which agglomerate and grow into final iron particles. This leaves a poorly crystalline Fe-O-Si bonded framework behind. STEM-EDS and STEM-EELS reveal low concentrations of silicon at the surface of the resulting iron particles, however they do not form encapsulating shells of fayalite as previously suggested. The majority of the silica remains in the Fe-O-Si material which may crystallise into separate fayalite particles at elevated temperature. The presence of silica in high proportions (100/100 Fe/SiO2 and 100/200 Fe/SiO2) results in the formation of a two-phase system consisting of silicasubstituted 2-line ferrihydrite particles which are encapsulated in an ironinfused amorphous silica network. As with the other silica-bearing samples, there is an increase in Fe-O-Si bonds and an increase in the degree of distortion at Fe3+ sites with increasing silica content. The large amount of silica suppresses the blocking temperature of the SPM crystallites. In a hydrogen atmosphere, the reduction to metallic iron follows the same three step process as the other silica-bearing samples. Reduction temperatures are further shifted to higher values and given reduction steps are considerably broader with increasing silica content. The fraction of iron not fully reduced also increases. Iron particle diameters are very small, since encapsulation by the silica matrix prevents growth of particles.

- Description: There is a great need for a pharmaceutical manufacturer to provide its customers with the right product at the right time, place and price and also to deliver the product in the right quantity and quality. Should pharmaceutical customers not receive their orders on time from the pharmaceutical manufacturer, the customers might face out-of-stock situations. As a result, the patients or customers might turn to an alternative product from a different pharmaceutical manufacturer, which has the required stock readily available. This could lead to loss in sales and even death amongst its customers. The main objective of this study was to determine the key factors that form part of the demand and operations planning strategies to ensure that these factors are in place to effectively manage and execute the supply chain and logistics processes to reduce possible out-of-stock situations amongst its customers. As a starting point to the study, an analysis was performed based on the review of relevant research and literature from various text books, journals, publications, as well as internet sources. The literature study covered various aspects such as demand planning, production planning, the use of different demand and operations planning strategies, as well as the importance of continuous internal and external customer service levels to ensure that customer orders are delivered on time. The analysis of the literature review was used to establish a theoretical basis for the design and structure of the questionnaire that was used as a research instrument in this study. A survey was conducted amongst the employees that are responsible for executing the supply chain and logistics processes within Aspen Pharmacare. These employees resided within the three main departments of the pharmaceutical manufacturer, namely, the Demand and Operations Planning, Production and Packing, as well as the Warehouse and Distribution departments. Each question posed in the questionnaire related to the role of each employee within these departments that are responsible for the logistics processes within Aspen Pharmacare. The empirical results from the study indicated that the respondents were in support that specific key factors are important for a pharmaceutical manufacturer to manage incoming customer orders efficiently and effectively to reduce possible out-of-stock situations amongst its end customers. However, the respondents also highlighted that there were a number of obstacles preventing them from implementing the key factors that are required to manage incoming customer orders more efficiently within the pharmaceutical manufacturer. Some of these obstacles include: the lack of pro- activeness; lack of accountability; and the lack of constant communication between the employees from the three main departments. Furthermore, incomplete hand-over information during shift changes amongst the employees of the Production and Packing department created unnecessary down-time. Also, the employees from the Warehouse and Distribution department were not informed timeously when changes to the production schedule were made. These obstacles will have a negative impact on the ultimate customer delivery dates and need to be addressed. The empirical results highlighted some recommendations to assist pharmaceutical manufacturing companies to more effectively and efficiently manage their incoming customer orders to reduce or eliminate any possible out-of-stock situations amongst its end customers. Some recommendations include: improved communication between the three main departments; to react immediately to out-of-stock products; and to ensure that internal and external customer service levels are adhered to at all times. The implementation of the recommendations based on the empirical findings of the study will assist the pharmaceutical manufacturing company to achieve excellence and to become a world-class supplier of generic pharmaceutical products. In this way, all incoming customer orders can be fulfilled on time.

- Description: Due to the importance of research in creating sustainability of knowledge, active research management has become a highly strategic function within progressive universities. The practice of research management and administration (RMA) in higher education and elsewhere has developed considerably over the last ten to fifteen years to become an activity that encompasses significant elements of institutional strategy, policy, governance, profile, finance, people management, postgraduate research, assessment, systems, and so on.The objective of the study was to improve research administration at the selected Higher Education Institution by investigating the role of strategic planning or an institutional research plan in the university‟s research portfolio and how effective and efficient it is in terms of research administration and service delivery to staff and students. A detailed literature review was conducted on the research trends in South Africa and globally, as well as on research management in higher education. A qualitative approach was used as the most appropriate research methodology for this study.In a selected South African university, the study investigated whether an Institutional Research Plan exists within its Research Office and whether the latter is effective and efficient with regards to research administration. A questionnaire was developed to survey the directors of the NMMU Research Office. Another questionnaire was developed to survey the postgraduate students‟ and staff members‟ perceptions about the quality of services that they received from the Research Office. The results were analysed and, based on the findings, recommendations were made for further research.The empirical results show that the selected higher education institution has an Institutional Research Plan located in the institution‟s Strategic Plan. Students and staff members surveyed in the study are largely satisfied with the services they received. The study also revealed factors that negatively impact the research office in this university, namely funding constraints due to historical political views about the institution; inadequate support from other support services within institutions; and uncompetitive salaries to attract and retain strong research academics. The study provides insights into the research function of the selected university and makes recommendations on how this function could be improved in other similar institutions. In this way, the study attempts to contribute to the body of knowledge on research management at higher education institutions.

- Description: This study was conducted in order to assess the effectiveness of technical analysis as a tool for financial security price forecasting. This form of analysis was examined so as to determine whether or not any benefit could be attributed to an investor or financial trader who applied it. Two technical trading strategies, consisting of three indicators each, were applied to fifteen financial securities over a five year period; so as to observe the price forecasting signals offered by the technical indicators. The resulting technical signals offered by the trading strategies were recorded and assessed for accuracy; allowing for various observations to be made; namely the forecasting precision of the technical strategies, the application of technical analysis in the equity and foreign exchange markets, the use of single or multiple technical indicators within a strategy, and the combining of technical analysis with fundamental analysis. The results indicated that the effective implementation of technical analysis could very well benefit the price forecasting practices of financial analysts and investors. However, it was determined that a fair amount of discretion on behalf of the analyst would be required when examining the signals offered by the technical indicators for the purpose of predicting financial security price movements.

- Description: The Northern Cape Department of Health (NCDoH) experiences sub-optimal programme management coordination in the delivery of health facilities. This research study aimed to determine how programme management coordination amongst the provincial office of the NCDoH, district office and the hospital that did undergo revitalisation through the Hospital Revitalisation Programme (HRP) could be improved. In order to explore the research problem the concepts of construction management and operations management were studied from which factors that impact positively and negatively on programme management coordination were extracted. A rationalist philosophical approach and subjectivist epistemology were utilised. The empirical enquiry was conducted through the case study method to obtain in-depth context of the case. The empirical evidence was obtained through a research interview guide utilising the purposive sampling strategy. The research initiated the sampling procedure by targeting the most relevant managers to the research study in the three units of analysis. A snowball approach evolved for the identification of other managers deemed relevant for purposes of this research. The thesis obtained opinions on the subject matter from managers who participated or were supposed to participate in the implementation of the delivery objectives of the administrative programmes in the NCDoH together with the objectives of the HRP. The research revealed that poor programme management coordination in the NCDoH as a result of internal competition and silo functions which prevent synergy from programme management plan development up to implementation. Furthermore, the complete building infrastructure only attains the objectives of construction management but the building infrastructure are not a complete justification for benefit realisation without the integration of operations management. The NCDoH cannot declare a successful programme management practices if it fails to realise the benefits that require integration of infrastructure and services. It is recommended that in order to attain effective programme management and realise the benefits of strategic objectives there should be a cross-functional approach from executive management which should trickle-down to the lowest level of administration. This research has developed a framework that can be useful in the integration of construction and operations management whereby infrastructure and operational services have to be delivered simultaneously in the field of programme management.

- Description: Resource subsidies are flows of nutrients from one ecosystem to another. Sandy beach ecosystems are at the interface between land and sea and thus receive nutrients from both land/seascapes. The seasonal nesting of sea turtles introduces large inputs of eggs, and so nutrients, onto sandy beach ecosystems, but little is known about the effects of these spatially and temporally variable nutrient input pulses on the dynamics of consumers in the recipient system. In this study, I examined the ecological role of sea turtles as vectors of nutrients that introduce large amounts of nutrients (in the form of eggs) from distant foraging grounds into nutrient-poor beach ecosystems. Although some of the nutrients return to the sea in the form of hatchlings, nutrients from unhatched and depredated eggs, dead and predated hatchlings, as well as chorioallantoic fluid and egg shells remain on the beach and presumably enter sandy beach food webs. I hypothesized that turtle nutrients significantly increase the availability of nutrients to sandy beach ecosystems and that those nutrients are incorporated by both terrestrial and marine food webs. These hypotheses were tested by comparing isotopic signatures of 13C and 15N of consumers on beaches with high and low turtle nest densities. The response of meiofauna to the decomposition of turtle eggs was also investigated. I predicted that meiofaunal abundance is positively affected by turtle nutrients and that higher meiofaunal abundances will be obtained in decomposing, depredated nests. I tested this hypothesis by comparing meiofaunal abundance in naturally predated nests to densities away from turtle nests (as a control). An in situ experiment that mimics conditions of naturally predated sea turtle nest, was set up to test meiofaunal community responses to turtle nutrients over time. The study indicates that sea turtle eggs represent a short pulsed resource subsidy that increases the nutrient and energy budget of sandy beach ecosystems. The results show that of the five potential nutrient pathways tested, ghost crabs appear to consume egg nutrients in measurable quantities, altering their diet and feeding behaviour according to food availability. The study also showed that there was a strong, but short-lived positive response of meiofauna to the introduction of nutrients, with increased abundance of all taxa in predated nests and experimental treatments. This response was particularly strong for nematodes which peaked in abundance after seven days. I conclude that turtle-derived nutrients represent a pulsed resource subsidy that makes significant contribution to the energy budget of sandy beach/dune ecosystems.

- Description: Background: Research has shown that men who have sex with men (MSM) experience stigma, discrimination, negative and judgmental attitudes and homophobia when accessing health care services. This has resulted in limited uptake of existing HIV and AIDS services. Further, the experiences serve as barriers to seeking and accessing public primary health care services. Negative psychological outcomes and in unique cases, adverse mental health outcomes have resulted from these experiences. Aim: The study aimed to explore and describe the experiences of a sample of MSM when accessing public health care services in Nelson Mandela Bay Municipality (NMBM). Method: A purposive sample of twenty-one MSM aged 22 to 30+ years, mainly black who lived in NMBM participated in semi-structured in-depth interviews. The study used the exploratory-descriptive qualitative design and thematic analysis was used to summarize findings. Findings: Findings from the study showed that MSM experience internalized stigma, perceived stigma, experienced stigma and HIV related stigma, resulting in minority stress. Experiences with health care services included long waiting time, lack of supplies, being attended to by different health care providers, health care provider insensitivity, comfort with health care provider and a need for integrating health services for MSM with general health services. Effects of stigma expressed by the men were non-disclosure of sexual orientation, reluctance to use public health facilities, negative mental health outcome and conformity to society. Conclusion: The study suggests that MSM public health services need to be improved and barriers to health access among MSM need to be addressed. Lastly, there is a need to address the health, psychological and social effects of stigma suffered by MSM.

- Description: The incidence of increased life span as well as a lack of care for older persons, gave rise to the South African Older persons Act (Act No 13 of 2006), which guides society in how our older persons should be treated. This Act also provides a clear indication of the expectations of caring for older persons within communities and families. Many older persons people rely on the relationships they have with their children in their golden years, to be fulfilling and loving. This study therefore aimed to explore the experiences of older persons and their adult children on maintaining positive relationships in order for the relationship to be most beneficial for both older persons and their adult children. The quality of relationships between adult children and older persons according to Newby (2010) can ease participation of adult children in the lives of older persons. This study was conducted from a qualitative research perspective that is exploratory, descriptive and contextual in nature. The exploratory-descriptive design allowed the researcher to understand the topic by using a narrative strategy of inquiry. A non-probability purposive sampling method was applied to identify five older persons as well as the adult children of these older persons who are retirees of an automotive company in South Africa. Individual, semi-structured face to face interviews were conducted with older persons as well as with at least one of their adult children who did not reside with them. Thematic data analysis technique was used to analyse the data collected. The study is viewed as significant in enhancing the understanding of satisfying and caring relationships between older persons and their adult children in order to add to the body of existing knowledge in social gerontology and to improve direct social work practice with older persons.

- Description: Financial market integration, in particular, portfolio allocations from advanced economies to South African markets, continues to strengthen volatility linkages and quicken volatility transmissions between participating markets. Largely as a result, South African portfolios are net recipients of returns and volatility shocks emanating from major world markets. In light of these, and other, sources of risk, this dissertation proposes a methodology to improve risk management systems in funds by building a contemporary asset allocation framework that offers practitioners an opportunity to explicitly model combinations of hypothesised global risks and the effects on their investments. The framework models portfolio return variables and their key risk driver variables separately and then joins them to model their combined dependence structure. The separate modelling of univariate and multivariate (MV) components admits the benefit of capturing the data generating processes with improved accuracy. Univariate variables were modelled using ARMA-GARCH-family structures paired with a variety of skewed and leptokurtic conditional distributions. Model residuals were fit using the Peaks-over-Threshold method from Extreme Value Theory for the tails and a non-parametric, kernel density for the interior, forming a completed semi-parametric distribution (SPD) for each variable. Asset and risk factor returns were then combined and their dependence structure jointly modelled with a MV Student t copula. Finally, the SPD margins and Student t copula were used to construct a MV meta t distribution. Monte Carlo simulations were generated from the fitted MV meta t distribution on which an out-of-sample test was conducted. The 2014-to-2015 horizon served to proxy as an out-of-sample, forward-looking scenario for a set of key risk factors against which a hypothetical, diversified portfolio was optimised. Traditional mean-variance and contemporary mean-CVaR optimisation techniques were used and their results compared. As an addendum, performance over the in-sample 2008 financial crisis was reported. The final Objective (7) addressed management and conservation strategies for the NMBM. The NMBM wetland database that was produced during this research is currently being used by the Municipality and will be added to the latest National Wetland Map. From the database, and tools developed in this research, approximately 90 wetlands have been identified as being highly vulnerable due to anthropogenic and environmental factors (Chapter 6) and should be earmarked as key conservation priority areas. Based on field experience and data collected, this study has also made conservation and rehabilitation recommendations for eight locations. Recommendations are also provided for six more wetland systems (or regions) that should be prioritised for further research, as these systems lack fundamental information on where the threat of anthropogenic activities affecting them is greatest. This study has made a significant contribution to understanding the underlying geomorphological processes in depressions, seeps and wetland flats. The desktop mapping component of this study illustrated the dominance of wetlands in the wetter parts of the Municipality. Perched wetland systems were identified in the field, on shallow bedrock, calcrete or clay. The prevalence of these perches in depressions, seeps and wetland flats also highlighted the importance of rainfall in driving wetland formation, by allowing water to pool on these perches, in the NMBM. These perches are likely to be a key factor in the high number of small, ephemeral wetlands that were observed in the study area, compared to other semi-arid regions. Therefore, this research highlights the value of multi-faceted and multi-scalar wetland research and how similar approaches should be used in future research methods has been highlighted. The approach used, along with the tools/methods developed in this study have facilitated the establishment of priority areas for conservation and management within the NMBM. Furthermore, the research approach has revealed emergent wetland properties that are only apparent when looking at different spatial scales. This research has highlighted the complex biological and geomorphological interactions between wetlands that operate over various spatial and temporal scales. As such, wetland management should occur across a wetland complex, rather than individual sites, to account for these multi-scalar influences.

These perches are likely to be a key factor in the high number of small, ephemeral wetlands that were observed in the study area, compared to other semi-arid regions. Therefore, this research highlights the value of multi-faceted and multi-scalar wetland research and how similar approaches should be used in future research methods has been highlighted. The approach used, along with the tools/methods developed in this study have facilitated the establishment of priority areas for conservation and management within the NMBM. Furthermore, the research approach has revealed emergent wetland properties that are only apparent when looking at different spatial scales. This research has highlighted the complex biological and geomorphological interactions between wetlands that operate over various spatial and temporal scales. As such, wetland management should occur across a wetland complex, rather than individual sites, to account for these multi-scalar influences.
