- Description: The purpose of this study was to develop a strategy to motivate continued usage of Learning Management Systems in higher learning institutions of Zimbabwe. A related goal was to identify unique challenges experienced by instructors in their use of LMSs. The use of LMSs is now global and has been fairly successful in developed countries even though past research shows that instructors tend to discontinue usage over a period of time. Whereas most LMSs research is carried in the context of the developed world, the candidate demonstrates that Vantankesh's IS Success Model and Davis' Technology Acceptance Model can be successfully replicated into the developing world on condition that local environment is taken into context. The results showed that LMSs in Zimbabwe higher learning institutions hold a promise of success even though challenges exist. The findings have wider implications on the need to invest in neccessary infrustructure and future predictions on learner interests. The study demonstrates that shared success can be achieved if the local conditions are taken into context when developing a strategy to motivate instructor continued LMS usage. The study holds the practical implication that institutions can motivate instructors to continue with usage of LMSs to deliver quality output in their daily duties.

- Description: The objective for this study was to explore the relationship between inflation and growth with an understanding of the effects of unemployment on growth. The primary objective of this paper was to investigate the existence of Phillips Curve, Okun’s Law, and Taylor Rule in Zambia on the basis that Zambia is a youthful economy, with a growing population, which is expected to temper with unemployment rates, as an increase in the supply of labour might be too high for the demand for jobs available. To be specific, the study aims at determining the relationship between inflation and growth and seeks to understand what policy measures have been undertaken to curb inflation and reduce unemployment in Zambia. To achieve this, a quantitative research was undertaken using the ARDL cointegration model in conjunction with sensitivity tests to cater for structural changes in the economy with 2007 standing as the break point, as well as paying attention to the fact that different policy regimes employed during the course of the data covered, that being, 1996 to 2017, would affect that rates of unemployment, inflation and growth of the country, across period under review. The study revealed that Zambia faces a Hybrid New Keynesian Phillips Curve during the period under study which is dominated by a mixture of both back-ward and forward-looking aspects of inflation. This specifically, paints the effects of inflation persistence as well future expectations of inflation on growth. Further, a cointegration relationship was established between unemployment and output, while Taylor principles were found not to apply to the Zambian economy, which have proved in other economies to be foundation blocks for good economic growth and as such significant to both fiscal and monetary policy authorities of the economy. The researcher therefore recommends that Zambian policy makers, that is, both the fiscal and the monetary authorities, work together in order to attain minimal and optimal levels of inflation to help achieve a conducive economic environment for the country.

- Description: Introduction: Obesity is a metabolic disease in which the accumulation of excessive fat in the adipose tissue may interfere with the normal maintenance of a healthy state. However, there is only a limited number of drugs approved for the treatment of obesity. For this purpose, target therapies are receiving more attention as a preferred treatment to reduce the burden of chronic diseases which are associated with the current strategies. Nanotechnology is a highly promising field that offers a nanotechnology-based drug delivery system as a novel means of solving issues associated with the toxicity of conventional anti-obesity drugs. Vascular targeted nanotherapy (targeted bi-functionalized nanoparticles) as a strategy that can overcome the current available anti-obesity drugs. Aim: This study sought to understand the effects of nanotherapy in the hepatic lipid metabolism and secretion of bile acids Research focus: The effects of gold nanotherapy on the bile acid biosynthetic enzymes, transporters and lipogenic enzymes of rats that were on a high fat diet. Conclusion: The study shows low expression in the majority of genes responsible for bile acid synthesis and a lipogenic pathway; therefore, the effects of nanotherapy exhibit low toxicity in the hepatic lipid metabolism.

- Description: This study sought to investigate the constraints in the attainment of sustainable human settlement in KwaMaphumulo Local Municipality at iLembe District in KwaZulu-Natal, South Africa. The aim of this study was to investigate the constraints that limit the achievement of the ideal of sustainable human settlement development in the KwaMaphumulo Local Municipality. Furthermore, the study sought to determine the impact of these constraints on sustainable development and to proffer measures that can be taken to combat stagnant or underdevelopment in the area. A mixed-method approach is followed in this study, which considers a triangulation of quantitative and qualitative data collection, analysis and interpretation techniques. It is important to note that in the past years since South Africa became a democratic country, there have been countless efforts with regard to overcoming the problems created during the apartheid era. These problems stemmed from a distorted spatial, social, economic and political background that was advocated by both segregationist public policies and the planning systems of the Apartheid Regime. In recent years, South African cities have also been faced with environmental issues, which are imperative to the future development of the country. With all these issues in mind, we see that the many efforts that are put in place by government always fall short of solving the problems. This research report looked at the constraints that affect the KwaMaphumulo Local Municipality in attaining sustainable human settlements and whether the efforts of redistribution and equality have been enough to overcome the problems. The key findings of the study were that constraints in attaining sustainable human settlements in the KwaMaphumulo Local Municipality negatively impacts on the development in the area. The level of services being provided is poor. There is an apparent disconnect between traditional leaders and the municipality councillor as development management and vision are concerned. Furthermore, the development programmes and projects do not seem to address the critical needs of the community. Housing development is narrow minded with a focus on the top structure and a failure to include basic services and infrastructure. Houses built that are financed by subsidies are of poor quality. The latter situation results in more able‐ bodied, skilled and capable people emigrating to developed areas.

- Description: Persistent depreciating human settlements is a global challenge, particularly in developing countries and this challenge contributes to the continuously increasing housing gap, despite several novel policies and programmes. Although there is a dearth of research-based literature on human settlements management, studies show that property management, Facility Management, housing management and urban management impact the sustainability of all these built environment milieus which form part of the human settlements’ sub-components. This research aimed at altering the afore-said challenge by exploring the management of human settlements in Nigeria and in South Africa. Philosophically, the research is pragmatic, and it rests on positivist deductive reasoning. The methods used for data collection include a review of literature, collection of archival records, and empirical studies of purposively selected professionals and stakeholders involved in human settlements’ management in Nigeria and in South Africa. The findings indicate that existing human settlements in the case studies are “good” and “acceptable” with the majority adopting an outsourced method of management. Furthermore, the lack of maintenance records, the deficiency in policy monitoring and the training of management and maintenance personnel were the three highest ranking factors indicated to be affecting human settlements management. Moreover, an inhabitant’s income, the time available for management, professional expertise and technology employed for management are recognised as the critical sustainability sub-factors affecting human settlement management. The factor analysis established ownership, human resource and capital, social, legal, technology, economic, physical and environmental factors as vital and very significant in achieving sustainable management of human settlements. The study recommends the professionalisation of the field of human settlements as well as a formulation of management policy among others. The study developed a management model for human settlements, and it advocates that human settlements managers, owners and organisations should apply the model in this study, to improve their human settlement management practices, so as to achieve sustainability, and in essence, Sustainable Development Goal 11. It is hoped that the suggested management model will influence human settlement policy development and review, the designing of human settlement management programmes including the framework for their ongoing monitoring and evaluation. The study furthermore contributes to the development of housing and human settlement curricula and evolving human settlement research in both developed and developing countries.

- Description: The South African rookeries of the South Western Indian Ocean (SWIO) loggerhead and leatherback regional management units have been continuously monitored for more than 5 decades, representing one of the longest-running sea turtle beach protection and monitoring programmes in the world. Although such conservation has been successful in protecting adults on land when they come to nest, it might not be enough to ensure population recovery if survival is not ensured across all life stages. Sea turtles are particularly vulnerable to direct threats and changing environmental conditions because they are long-lived, slow maturing, and have low survival rates at early life stages, making them conservation-dependent. These characteristics also render them difficult to conserve as a consequence of their wide geographic distributions, spanning multiple jurisdictions and legislative systems with different conservation targets, and a complex life cycle with changes in habitats and diets at different life stages. Sea turtle populations have been severely depleted as a result of historical over-exploitation and current threats including fisheries bycatch, direct harvest, habitat loss, pollution and pathogens, and climate change. In many cases however, population declines have been reversed by a variety of effective conservation measures such as beach protection programs, and marine protected areas, enabling successful population recovery around the world. Despite protection and apparent increase in abundance, indirect pressures can still affect turtle populations. Therefore, it is fundamental to evaluate the effectiveness of conservation measures (using fitness traits such as female and hatchling sizes) and examine underlying trends. The aim of this thesis was thus to evaluate the fitness of loggerhead and leatherback sea turtles nesting in South Africa. Long-term female size trends over time were evaluated and the populations were split between first-time nesters and experienced nesters. As sea turtle reproductive output (clutch size only) is correlated with female size and evidence is showing that in some populations individual female size is decreasing, the effects of maternal body size on reproductive output and hatchling fitness were investigated for both species. Crawling and swimming speeds were used as proxies of hatchling fitness, because these two traits positively influence their survival. An oceanic model was further used in combination with a particle tracking framework to estimate, for the first time, post-hatchling dispersal of loggerhead and leatherback turtles in the SWIO. I investigated whether the trend in female size for loggerhead turtles nesting in South Africa is a result of their foraging strategy to determine if there is a foraging dichotomy (neritic and oceanic). Despite an apparent increasing population, a significant 3.7 and 3.6 cm decrease in the size of both recruit and remingrant female loggerhead turtles, but a stable mean size of leatherbacks for both age groups was observed. I hypothesise that these contradictory effects are attributable to the very distinct foraging ecologies of the two turtle species and speculate that these variations in carapace length may be driven by environmental change. The reproductive strategy of both loggerhead and leatherback turtles nesting in South Africa supports the optimal egg size theory with larger turtles producing larger clutches but not larger eggs. Egg size was thus constant irrespective of maternal length. Hatchlings with longer carapaces and flippers had higher swimming speed, suggesting that larger hatchlings are fitter (potentially higher survival) than smaller ones by spending less time in high predation risk areas (i.e. beach and nearshore). The model revealed that dispersal trajectories of both loggerhead and leatherback sea turtle hatchlings were very similar and simulations indicated that initial active swimming (frenzy) as well as variability in oceanic conditions strongly influenced dispersal of virtual hatchlings. The trends observed in this study emphasize the importance of long-term monitoring, examining not only abundance but also individual size, to understand population dynamics, support recovery planning and prioritize future conservation practices. Furthermore, the findings of this study have important implications for overall population growth if smaller hatchlings of lower fitness are produced as a result of climate change and thus have decreased dispersal abilities and lower likelihood of survival.

- Description: The goal of this study was to carry out a comprehensive assessment of the quality of healthcare in the Port Elizabeth Hospital Complex in the province of the Eastern Cape in South Africa. The assessment was made on the basis of the perceptions of patients of the features of the hospital and the services which it provides to patients. A quantitative research design was adopted to conduct the study. The data was derived from a questionnaire which the research assistants administered to patients in a number of surgical clinics in the hospital. Across-sectional sample of 350 patients, who were making their first follow-up visits after having previously been admitted to the hospital to undergo surgical procedures, was obtained by making use of convenience sampling. The researcher made use of the modified SERVQUAL scale for hospital services in order to measure the extent to which the participants agreed with statements pertaining to five specific dimensions of the quality of service, namely, tangibles, reliability, responsiveness, assurance, and empathy. The overall gap score was negative (-0.52), which indicates that the respondents perceived that the quality of healthcare which the hospital provided was unsatisfactory. Although the gap scores for each of five of the dimensions of quality were negative, the two dimensions whose gap scores reflected the highest levels of dissatisfaction were reliability (-0.66) and responsiveness (-0.63). The findings of this study could assist the Department of Health of the Eastern Cape Provincial Government to appreciate the perceptions of the public of the quality of healthcare which the Port Elizabeth Hospital Complex provides to patients. The recommendations which are made on the basis of the findings of this study could assist policymakers and members of the senior management of the hospital complex to formulate policies which result in substantial improvements in the quality of healthcare in the hospital complex. Further research is still needed to identify the factors which adversely affect the performance of the staff of the hospital and limit their ability to provide satisfactory healthcare consistently to patients.

- Description: The goal of this study was to carry out a comprehensive assessment of the quality of healthcare in the Port Elizabeth Hospital Complex in the province of the Eastern Cape in South Africa. The assessment was made on the basis of the perceptions of patients of the features of the hospital and the services which it provides to patients. A quantitative research design was adopted to conduct the study. The data was derived from a questionnaire which the research assistants administered to patients in a number of surgical clinics in the hospital. Across-sectional sample of 350 patients, who were making their first follow-up visits after having previously been admitted to the hospital to undergo surgical procedures, was obtained by making use of convenience sampling. The researcher made use of the modified SERVQUAL scale for hospital services in order to measure the extent to which the participants agreed with statements pertaining to five specific dimensions of the quality of service, namely, tangibles, reliability, responsiveness, assurance, and empathy. The overall gap score was negative (-0.52), which indicates that the respondents perceived that the quality of healthcare which the hospital provided was unsatisfactory.

- Description: Between the point of arrest and conviction, an accused person has a right to be released on bail based on his or her Constitutional right to liberty as well as the right to be presumed innocent. To grant bail to an accused person serves as a form of contract of insurance or a guarantee that if the accused person is released pending the determination of the case against him, he will not frustrate the course of justice and will appear at a later date to face trial. The essence of bail is to allow the accused person enjoy his right to liberty pending the determination of the criminal charge if the interest of justice will permit for his or her release. This study aims at comparing bail proceedings in both the Nigerian and South African criminal justice systems. The constitutions of both jurisdictions make provision for bail, as well as the Administration of Criminal Justice Act applicable in Nigeria and the Criminal Procedure Act which is applicable in South Africa. By comparing both jurisdictions, the similarities and differences that exist between both systems will become evident, which makes them unique and distinct of each other. During the course of this study, it will be discovered that the Nigerian bail procedure do not meet up to international standards in protecting the right to personal liberty of accused persons. It is believed that the recommendations that will be suggested in this study will improve the Nigerian bail procedure and make it more effective and efficient.

- Description: Potatoes are an important crop in the Eastern Cape, and in South Africa as a whole, as a nutritious staple food. For consumers, they provide a quality, relatively low-priced form of carbohydrate and, for farmers, they are a valuable cash crop. The nutritional requirements of Solanum tuberosum L., in particular its nitrogen (N) needs, during cultivation is an aspect warranting further research. The Eastern Cape is a prime potato-producing region and, as such, is an appropriate and logical choice in terms of a suitable location for the required study. Improper farming practices with regards to improper fertilizer application techniques can adversely affect yields, and excessive application of fertilizer is fundamentally economically unsound, adverse towards the environment and potentially detrimental to the crop. It is therefore imperative that nutrients – and nitrogen in particular – are available to the crop in the correct quantities at the correct time. The objective of this dissertation was to accurately identify the nitrogen fertilizer needs of potatoes – with specific emphasis on whether or not nitrogen affects stolon growth and development. The potato cultivar used in the research trial was Mondial, which is a cultivar well-established in the region. Nitrogen applications needed to be closely monitored with regards to the total seasonal amount of nitrogen applied, the timing of applications and the amount applied at each application. Meaningful data accumulated from this study will help farmers in the area to accurately assess the efficiency of their farming operations. Excessive or insufficient plant nutrition affects tuber bulking and quality. The objective was to accurately identify this “sweet spot” (i.e. the optimal measure and timing) with regards to fertilization, especially nitrogen, while also taking into account various other factors that affect healthy tuber development and stolon formation. The untested assertion that prompted this study was that too much nitrogen adversely affects the number of stolons – and therefore, the number of tubers, since tubers grow from the stolons. It is generally accepted that too little N will adversely affect yields and yield potential will not be achieved, and that too much N will adversely affect yields, incur unnecessary costs and potentially degrade the environment. Optimum nitrogen application quantities were therefore identified, along with points at which deviations from optimum yields occurred. There were 8 distinct treatment combinations – namely: a rate of 150kg/ha, 250kg/ha, 350kg/ha and 450kg/ha – of nitrogen (N) throughout the growing season, administered at 2 different timings (hereafter referred to as the Application Timings). The applications of nitrogen were administered as follows: Application Timing 1 (50% N at planting : 25% N as Topdressing 1 : 25% N as Topdressing 2) and Application Timing 2 (75% N at planting : 12.5% N as Topdressing 1 : 12.5% N as Topdressing 2). The findings suggest that while nitrogen played a role in increasing yield, there was no conclusive evidence to suggest that stolons were weaned by excessive amounts of nitrogen throughout the growing season. The results obtained from statistical analysis showed that, between Application Timing 1 (50%:25%:25%) and Application Timing 2 (75%:12.5%:12.5%), neither split application timing was superior to the other in terms of tuber yield or effect on the average number of stolons when data from all three plantings were combined. In some instances, high stolon numbers were observed in the high N application plots. The highest stolon count in a single data collection in Planting 1 was in the 450kg/ha App. 1 plots in the 3rd data collection. The highest stolon count in a single data collection in Planting 2 was in the 250kg/ha App. 2 plots in the 2nd data collection. The highest stolon count in a single data collection was in the 350kg/ha App. 2 plots in the 3rd data collection. The conjecture that excessive nitrogen causes stolon weaning in potatoes was not supported by the findings of the experiments conducted in the three trial plantings which constituted this research study.

- Description: Social Network Services (SNSs) have revolutionized the way we communicate, interact and present ourselves before others. The business model of SNS’S like Facebook is primarily based on SNS’S user self-disclosure of personal information. It is argued that the SNS’S user conducts a cost-benefit analysis before deciding to self-disclose their personal information, and this user behaviour forms the basis of the Privacy Calculus Theory. Enjoyment, Self-Presentation and Relationship Maintenance is considered as the benefits and the Privacy Concerns of the users is considered as the costs of disclosing personal information.As national or regional culture could influence SNS’S user self-disclosure behaviour, it would be advantageous for multinational SNS’S’s like Facebook to understand the perceptions of SNS’S user’s from different nationalities. Currently, no studies have been conducted amongst the South African (SA) SNSs’ users’ self-disclosure behaviour. This research is aimed at understanding the South African SNSs’ users’ perceptions regarding their perceived costs, benefits and selfdisclosure using the Privacy Calculus theory. This study is a replication of a similar study undertaken amongst the United States of America (US) and German SNS’S users. To remain competitive in the market and to sustain the viability of their business model, SNS like Facebook will have to encourage user self-disclosure. Studies have proven that national cultures play an important role on the nature and extent of user disclosure (Krasnova & Veltri, 2010; Lewis, Kaufman, & Christakis, 2008). However, no similar research has been undertaken in South Africa, and currently we do not understand South African SNS users’ self-disclosure behaviour in terms of the privacy calculus theory. The primary objective of this study is to understand the perceptions of South African SNS’S users regarding the perceived benefits, costs, moderating factors and self-disclosure, using the Privacy Calculus Theory. To achieve this objective, we initially undertook a detailed literature review to understand the concept of information privacy, privacy calculus, information privacy policy and legal framework, SNS’S and self-disclosure and the various factors affecting self-disclosure. We then proceeded to validate the theoretical framework by collecting data from two South African universities, namely the Nelson Mandela University (NMU) and Walter Sisulu University (WSU (NMD Campus – Former University of Transkei)), by adopting the same methodology and instrument used in the original study (and the isiXhosa translation). The theoretical framework used for this study is based on the Privacy Calculus theory, which argues that users conduct a cost-benefit calculus before deciding to self-disclose their personal information. This analysis is further influenced by other moderating factors like trust, control and awareness. All these factors have been incorporated into the theoretical framework and the instrument, adapted from the original research was used to collect data from the participants. The data from 239 respondents, who finally qualified for analysis was collated and proceeded with the analysis of that data. The data was analysed in four stages using established statistical tests. The first three phases were used to determine the actual value placed by the users on selfdisclosure, its determinants and moderating factors, and the last phase concentrated on how each of the constructs included in the theoretical framework influenced the other constructs. The results obtained from the analysis provided valuable insights into the self-disclosure behaviour of South African SNS’S users. Entertainment was the primary benefit the students derived from using SNS like Facebook, followed by relationship maintenance and those who enjoyed the platform more tended to Self-Disclose more. Those who tended to derive more benefits from the platform were found to trust the platform and the other users of the network. The theoretical framework was validated and it was determined that privacy paradox exists within the South African SNS’S user community, meaning that even with high privacy concerns, these SNS users are willing to self-disclose their personal information.

- Description: This study employs the panel cointegration and Pooled Mean Group technique to examine the effects of economic growth on greenhouse emissions using the panel data from the period of 1970 to 2014 for five Southern African Development Community group of countries. The increase in the combustion of burning fossil fuels has become the global threat in environmental quality. The Environmental Kuznets Curve hypothesis postulates that at the primary stages of industrial economies there is more extracting of natural resources and more agricultural activities taking place as a result the waste generation and resource depletion accelerate. However, as the economic development improves more, the curve reaches a threshold where it starts to decline due to the increase in economic growth and the change to information-based industries. Based on the empirical evidence, the variables of this study were found to be stationary at first difference and integrated of I(0) and I(1) using Im, Pesaran & Shin W-stat, Fisher ADF, and Levin, Lin & Chu panel unit root test. The existing long-run relationship between the variables were found in both the Pedroni and Kao cointegration test and were significant at 5% in finding the relationship between the variables. The Pooled Mean Group demonstrated mixed results in the study’s regressions, monotonic relationship was found between carbon dioxide and economic growth. The strong existence relationship between economic growth and energy consumption was found to be significant at the 1% level. These results are in line with the EKC hypothesis, which assumes that as the income level increases the society will start to be environmentally friendly and the technology advancement will decrease the emission of pollutants. In addition, in finding the causal relationship between variables, the researcher used the Granger causality test, with the results from this test revealing a unidirectional and bidirectional relationship between all the chosen variables. These results are important for policy makers.

- Description: Employee wellness and work engagement have a positive influence on organisational behaviour. The main aim of the research study was to understand whether a relationship existed between employee wellness and work engagement in a Non-Governmental organisation (NGO). The research used a cross-sectional design and a composite questionnaire to measure employee wellness and work engagement. This was a paper and pen-based questionnaire which was distributed to 160 employees. Of the 160 questionnaires distributed only 155 participants responded. These participants are employed at NGO’s based in Port Elizabeth, Johannesburg and East London. An exploratory factor analysis determined a new more reliable factor structure for PWS. Employee wellness lost items and became a three-factor structure. The results showed that the new EFA model was best suited for the present study. Work Engagement remained a three-factor structure. T-tests and ANOVAs revealed significant differences between the constructs and the demographic groups. Correlations showed the main findings of the study to be a relationship between employee wellness and work engagement in a non-governmental organisation.

- Description: The continuous flow synthesis of trimethoprim, an antibiotic, was investigated in this study from simple commercially available reagents, such as aniline and dimethylamine. The first step of the synthesis involves a highly exothermic Michael reaction, between acrylonitrile and dimethylamine; process intensification through miniaturization provides a safe and efficient method of synthesis through the use of microreactors. This is afforded by their large surface area-to-volume ratio; one of the many characteristics of continuous flow synthesis that allows for rapid heat dissipation allowing for exothermic reaction to be conducted safely at ambient or higher temperatures. This study was optimized on a Chemtrix Labtrix® Start unit using a Chemtrix reactor achieving a conversion of 99% in 12 sec residence time at 25oC. Subsequently the base catalyzed condensation of the intermediate with 3,4,5- trimethoxybenzaldehyde was investigated using Little Things Factory reactors (Channel diameter: 1.0mm). Maximum conversion (100%) was obtained at 80oC in 20 mins. Due to the poor cyclisation observed with this intermediate, according to literature findings, the 3-dimethylamino group was substituted for aniline. The optimisation for this acid catalysed substitution reaction was performed on a homemade PTFE tubing reactor (Diameter: 0.5mm) and it was found that at 120oC in 10 mins residence time a conversion of 97% was obtained. From the results obtained, an investigation into an integrated process for the condensation and substitution reaction was done using the Little Things Factory system (Channel Diameter: 1.0mm) coupled with a homemade PTFE coil reactor (Diameter: 0.5mm). This process, under optimum conditions of temperature 80oC and residence time of 30 mins, attained a conversion of 76%.

- Description: The primary aim of this study was to compare the Index of Coordination (IdC) for both sprint and endurance swimming and running of less-skilled level triathletes. The researchutilised a quantitative approach, specifically exploratory, with a one group post-test-only research design. Twenty participants from the triathlon community, ages 18 years and older, were selected via purposive and convenient sampling. The participants were expected to complete a total of four physical tests, namely 50 m sprint swim, 1500 m endurance swim, 50 m sprint run,and 5000 m endurance run, on four separate days, over a period of two weeks. The data was collected by video recording each participant performing each of the four different tests andcoded frame-by-frame onDartfish Video Solution (10.0).The IdCwas derived by identifying the time-in markers and time-out markers for both left and right arms when swimming; and by identifying the time-on markers and time-off markers for both left and right legs when running. The results revealed significant differencesbetweenthe IdCvalues ofsprint swimming and endurance swimming(p<0.001); sprint running andendurance running(p<0.001); sprint swimming andsprint running(p<0.001); andendurance swimmingandendurance running(p<0.001).The top performersin each testwere significantly faster than bottom performers(sprint swimming: p<0.001; sprint running:p<0.001; endurance swimming: p<0.001; endurance running: p<0.001) but no significant group differences on associated IdC were found(sprint swimming: p=0.535; sprint running: p=0.857; endurance swimming: p=0.132; endurance running: p=0.775).Bothendurance tests were divided into three equal portions and it was found that 23% ofthe fastest trial endurance swim time can be explained by the IdC obtained in portion three(p=0.032); and that 62% of the fastest trial endurance run time can be explained by the IdC obtained in portion one(p<0.001). The overall findings of the study suggest that an IdC mode is considered efficient relative to the environmental contextand thatIdCis relative to skill level or alternatively independent of performance times. The IdC, therefore, remains inconclusive as an alternative method but warrants further investigation particularly in longer distance endurance events.

- Description: In the twenty-first century the internet has become a pervasive part of individuals’ lives and their relationships, changing the way individuals connect, develop and maintain their romantic relationships. The way in which couples use the internet can have a significant impact on their relationship satisfaction, which is often a predictor of the length and success of their relationship. Although the internet is valued for many features, the nature of the internet creates the risk for some individuals to become addicted to the medium which is associated with psychological and relational difficulties. The present study aimed to explore the impact of problematic internet use on individuals’ satisfaction with their offline intimate relationships. A quantitative, non-experimental, cross-sectional, research design was utilised, where participants from Nelson Mandela University completed an online survey (N=388). A non-probability, purposive sampling method was employed with an inclusion criteria which required participants to have daily internet access and to be in a committed romantic relationship. The study analysed four primary variables, namely, online preoccupation, adverse effects of online behaviour, social interactions and general relationship satisfaction. The results of the study were discussed through the lens of the Couple and Family Technology (CFT) framework to explain the processes that underlie the relationship between these variables and indicated that problematic internet use and relationship satisfaction is negatively related. The present study contributes to the body of literature and offers indications for future, in-depth research studies within the field of cyberpsychology.

- Description: The South African Government has institutionalised a Corporate Governance of ICT Policy Framework which was developed by Department of Public Service and Administration (DPSA). The framework has adopted some elements of KING III, ISO 38500 and COBIT. Consequently, it is now a requirement by the South African Government that all its entities must adopt this framework. Nevertheless, it is not clear how government has emphasised this alignment in such entities. The problem statement in this study was that Randwater is unable to realise full value of the investment in IT/IS because there is misalignment between IT objectives or deliverables and the corporate objectives. This study sought to identify a suitable framework which meets the ICT policy criteria as set out by the DPSA, which will facilitate the alignment between corporate objectives and IT/IS objectives at Randwater. This was achieved through the development and refinement of the artefact through the various iteration phases. Additionally, an online survey was used to collect data from a focus group comprising IT experts and senior management at Randwater. The Information Technology Governance Institute Framework was employed to assist in the development of the questions. The survey results were utilised during the validation of the artefact produced by this research study in a workshop. The findings were then linked with the related literature which either supported or rejected the findings through discussions on the literature and thereafter conclusions were made based on these findings. Furthermore, a literature review was conducted to gain a better understanding of what has been done in the field of research in order to assist in defining the problem that this research seeks to solve so as to inform the development of design characteristics. The research process employed the Nelson Mandela University – Design Science Strategy Methodology referred to as (NMU – DSSM) with the goal of developing an artefact in the form of a framework. The research process entailed studying the existing literature and analysing the aspects relating to corporate governance, IT governance, frameworks, and strategies to be able to measure the degree of alignment. The phases of designing the artefact were analysis, design, evaluate, validate and diffuse phases. The final artefact developed was a framework that incorporated the principles of King IV and ISO 38500 in corporate governance and ICT goals alignment. The final artefact also embedded transparency, accountability and security as important elements in the implementation of the artefact. The survey findings were instrumental in the development of the artefact that brings alignment between business strategy and IT objectives at Randwater. From the findings, in terms of IT flexibility, it was revealed that the interrelated parts of the system at Randwater were modular. It was also concluded that there is lack of communication about the manner in which the components of the information systems are organised and integrated in order to allow for rapid changes and that the organisational IT infrastructure and applications were loosely coupled. The findings further revealed that the business had established corporate rules and standards for hardware and operating systems to ensure platform compatibility. It was also revealed that organisational IT applications were developed based on compliance guidelines. In terms of IT-enabled dynamic capabilities, it was revealed that IT systems at Randwater are not capable of scanning the environment and identifying new business opportunities and are not capable of anticipating discontinuities arising in the business domain by developing greater reactive and proactive strength. It was also revealed that it was concluded that IT systems were capable of achieving strategic alignment between IT flexibility and dynamic capabilities. Therefore, design science was the ideal research paradigm towards addressing the research problem and the artefact designed was a viable research contribution. The significance of the study was that it contributed to the development of technology-based solutions to an important and relevant business problem of alignment of business strategy to IT goals. The design evaluation, the utility, quality, and efficacy of the final design artefact was rigorously demonstrated via well-executed evaluation methods. The study also contributed to the literature

- Description: The research study in Vuwani Vhembe district sought to investigate demarcation disputes, the relationship between service delivery and demarcation disputes. The study further investigates the role of municipal demarcation board and local government adherence to sound governance principles and the causes of the demarcation dispute in Vuwani. The study additionally examines the conceptions and misconceptions, their impact on the current demarcation disputes in Vuwani. It further intended to establish the role and involvement of Vuwani stakeholders such as traditional structures/ leaders, civil unions, community members etc. in the processes of demarcating Vuwani. “What is the cause of Vuwani community member’s rejection of the re-demarcation, which is said to correct the past spatial injustices and promote municipal sizing, thus enabling better performance in service provision by municipalities?” The study employed a mixed-method involving the use of both quantitative (mini-survey) and qualitative (use of in-depth, semi structures interviews and focus group discussions). Research findings suggest that re-demarcation is a sensitive aspect/process in South Africa, mainly due to the past Apartheid era. There was forceful removal of people from their land supported by Apartheid legislation such as the Native Land Act 1913, Group Act 1950, Native Resettlement Act 1954 etc. Thus, fears of the past Apartheid system cloud any attempt to correct spatial injustices of the country. The new democratic South African government, therefore, needs to be cautious in its acts to correct the spatial injustices, thus adhering to sound governance principles. Findings reveal that several misconceptions and lack of adherence of good governance principles by the Municipal Demarcation Board and Local government have, to some extent, fueled the demarcation disputes in Vuwani. Municipal performance in the rendering of service delivery has a major impact and contributes to the community’s acceptance or rejection of demarcation/ amalgamations. The study further reveals that in Vuwani municipal performance with the establishment of the new Collins Chabane municipality has been clouded by fear of the unknown as this form of “demarcation of establishing a new municipality” altogether is relatively new. Rural land authority, the role of traditional leaders, ethnicity ties have all been found to have contributed to the disputes in Vuwani. Limpopo Province is home to three ethnic groups, namely, vaVhenda, baPedi and xiTsonga. The study findings have presented traits of tribalism as contributing to on-going demarcation disputes in Vuwani.

- Description: Sexual and reproductive health education in South Africa appears to be failing young people as evidenced by the numbers of unplanned pregnancies and sexually transmitted diseases resulting from poor sexual health decision making. High-risk behaviours amongst youth are likely to be a product of the interplay of multiple risk factors on individual and interpersonal levels. The Auntie Stella: Teenagers Talk about Sex, Life and Relationships, is a sexual and reproductive health education toolkit with developmentally timed interventions for sexual and reproductive health education for adolescents. This tool kit has been successfully utilized in such countries as Zimbabwe, Tanzania, Malawi, Mozambique and Zambia. The study aimed to establish if the University health care professionals, including HIV counsellors and nurses, perceive Auntie Stellato be a useful sexual health and reproduction education programme to generate knowledge and prompt and promote safer sexual behaviour. An exploratory descriptive qualitative research design was be utilized, and purposive sampling was employed. Data was collected via focus groups where the toolkit was administered and discussed. Six focus groups were conducted with 12 participants from the Nelson Mandela University’s Campus Health Clinics. The data obtained was analyzed using Braun and Clarke’s (2006) six-step method of thematic analysis. The findings of this study revealed that the Nelson Mandela University health care professionals perceived the Auntie Stellatoolkit as being useful and applicable to the university context in terms of relatability. They expressed thatthe programme is ideally youth-friendly and appropriate for university students. The findings of this small study may have important implications for future research of implementation of sexual and reproductive health education programmes in Higher Education Institutions.
