- Description: The purpose of the study is to determine the effect of the down referral chronic medication distribution system on patient's adherence to chronic medicine in Buffalo City sub - district by ensuring that chronic patients receive their correct medication on time and in correct quantities every month so that they can take the medication as recommended by the health professional. Adherence to chronic medication lead to better health outcome and reduced hospital re-admission. A non-experimental and descriptive quantitative research methodology was used. A data abstraction form developed by the researcher was used to record data from the medical records of chronically ill patients. The results of the study revealed that most of the chronically ill patients who were admitted to hospital were not adherent to their chronic medication. Patients are non-adherent even if they have chronic medication with them. This was evident in the number of patients who do not remember how many days did they not take their treatment. Others indicated that they share their medication with other family members who suffer from the same chronic condition. The patients' lack of understanding of their chronic condition and the consequences of not taking medication as instructed by the health professional contribute to non-adherence. Strengthening of health promotion programmes to educate the patients about their chronic condition would improve adherence. Most of the chronic conditions are life-style modifiable diseases. Patients must be educated about the changes they can make to improve their quality of life.

- Description: Background: HIV/AIDS is a major global public health problem. The higher education sector too, is affected by the scourge of HIV/AIDS. Universities are considered to be high- risks areas for HIV infection because many students indulged in high risky behaviour link to HIV infection; therefore developing ways to prevent students for acquiring HIV and as well reducing HIV prevalence rates through training and teaching about HIV/AIDS will contribute to change in behaviour of students. Anecdotal evidence suggests that the majority of the students at Fort Hare lack the general awareness and education in HIV/AIDS due to lack of information coupled with their general disadvantaged background with the ultimate result being threatened by high infection rates. The University of Fort Hare (UFH), in a bid to capacitate the academic staff in respect of the laudable initiative to integrate HIV/AIDS in curricula, decided to embark on a pilot study that is anticipated to form fundamental strategies to sustainable HIV/AIDS curricula integration across all faculties, at least by the end of 2030. The university has planned to engage in the curriculum integration process by implementing a two year cycle pilot study during the grant period. Aim: The main aim of the study was to assess the challenges faced by students and educators concerning the integration and implementation of HIV/AIDS curriculum at the University of Fort Hare. Methods: The study adopted a quantitative, explorative descriptive design to examine the challenges associated with the Integrated HIV/AIDS curriculum at the University of Fort Hare. The target population was the educators and students who had training and teaching in the Integrated HIV/AIDS curriculum. A purposive sampling was used to select 487 students and 23 educators from across three departments: Nursing Science, LKA (Life, Knowledge and Action) and Law involved in the HIV/AIDS Curriculum Integration programme at the university. A self-design questionnaire was used for data collection focusing on the demographic profiles of the participants, the teaching strategies and methodologies adopted in the Integrated HIV/AIDS curriculum, the usefulness and relevance of the newly integrated HIV/AIDS curriculum content in addressing the needs of the students and the community, and the challenges faced by the educators and students in the Integrated HIV/AIDS curriculum. Ethical approved was obtained from the Research Ethics Committee of the University of Fort Hare. Permission was obtained from the participants through written consent forms. The data was analysed using descriptive statistics (frequency counts, percentage, means and standard deviations (SD)). The Chi-square test was used to examine the relationship between the variables of interest across the departments. A p-value of 0.05 was set for statistical significant testing. Results: The majority of the participants have adequate knowledge of HIV transmission, as 93.2 percent indicated HIV can be contracted through unprotected sex, sharing of needles (92.1 percent), receiving a blood transfusion that has not been screened for HIV (83.9 percent), sharing razor blades that has not been disinfected (83.0 percent), and having more than one sexual partner (86 percent). Age, gender, race and department were significantly associated with knowledge of route of HIV transmission. The present study indicated that the participants experienced several challenges during the teaching of the Integrated HIV/AIDS curriculum. Time allocated was the biggest challenge (58.3 percent), followed by undated materials, and curriculum overloading and teaching. The study indicated that majority of the students would like to compile a portfolio of evidence in the teaching of HIV, followed by creative arts, DVD/movies, and internet research. The majority of the lecturers preferred to teach HIV/AIDS through expressive arts, followed by role play, and formal lectures. The majority of the participants stated that HIV/AIDS information would be useful to them to apply in their communities and in their profession (97 percent), emphasizing that such knowledge and information will empower them to participate in roadshows and voluntary work at HIV/AIDS Shelters. The findings of this study pertaining to the challenges faced by educators during the implementation of the Integrated HIV/AIDS curriculum revealed that the majority of the participants stated that the HIV information was not updated, heavy workload, and adequate training. The lecturers expressed that they would prefer to teach HIV/AIDS curriculum by expressive art through drawing and creating art that expresses HIV and the relevance in the students’ community. Conclusions: Majority of the students received teaching of HIV as part of a course, and HIV teaching as an integrated component in a subject, while few received it as a stand-alone subject offered by a lecturer/facilitator. The present study indicated that the participants experienced several challenges during the teaching of the Integrated HIV/AIDS curriculum. Time allocated was the biggest challenge (58.3percent), followed by undated materials, and curriculum overloading and teaching. The majority of students preferred HIV/AIDS to be taught by their peers experience in HIV, by face-to face by a person who is HIV/AIDS infected or affected. The majority of the lecturers preferred to teach HIV/AIDS through expressive arts, followed by role play, and formal lectures. The majority of the participants affirmed the relevancy of HIV information taught. They further indicated that the information and knowledge gain would able them to make informed decisions on sexual behaviour. The majority of the participants stated that the HIV information was not updated, heavy workload, and adequate training. Most of the educators used formal lectures, followed by compilation of a portfolio of evidence, storytelling, DVD and movies, and experiential learning in hospitals and clinics in teaching HIV/AIDS integrated curriculum. The lecturers expressed that they would prefer to teach HIV/AIDS curriculum by expressive art through drawing and creating art that expresses HIV and the relevance in the students’ community. It is recommended that student’s involvement in the decision making processes of the integrated HIV/AIDS curriculum at the University of Fort Hare would make the programme more successful. HIV/AIDS resource materials need to be updated regularly and relevant to provide educators with specialized knowledge to be able to teach HIV/AIDS.

- Description: Assessing the outputs and outcomes of wetland rehabilitation activities is recognised by the 'Working for Wetlands' programme in South Africa as important, but to date has been limited. An assessment of the ecological outcomes and the structural outputs of the Working for Wetlands rehabilitation implemented in the Killarney and Kruisfontein wetlands, KwaZulu-Natal, in 2005 was undertaken. The assessment of outcomes included an evaluation of the changes in terms of ecological integrity and the supply of ecosystem services, using WET-Health and WET- EcoServices assessment techniques respectively, and vegetation composition. Improvements in hydrological and geomorphic integrity were recorded in both wetlands, resulting in improved ecosystem services delivery. However, investigation of vegetation composition using the Wetland Index Value and Floristic Quality Assessment Index showed that, seven years after rehabilitation, KiNamey's vegetation composition had improved, but Kruisfontein's vegetation was still largely dominated by pioneer species and appeared to be stable, but in a severely transformed state. The response of these wetlands has shown that sites for rehabilitation should be screened before work begins, and wetlands requiring intensive management of vegetation recovery should be assessed in terms of the objectives and the anticipated benefits of the project. The assessment of the outputs included an evaluation of structural integrity, survival and cost- effectiveness. Limited issues, mostly relating to deviations from the designs during construction, were identified with regards to the structural outputs at each of the wetlands. However, the spreader canals at both Killarney and Kruisfontein wetlands were not functioning as intended and concentrated flows from the spreader canals were evident in both wetlands. The use of spreader canals should therefore be carefully planned and implemented for future wetland rehabilitation projects. Consideration of ZAR per hectare equivalent re-instated/secured provided a useful initial means of determining the cost-effectiveness of the wetland rehabilitation. However, additional factors need to be considered, such as, the nature of the rehabilitation activities, the type and size of the problem being addressed, rehabilitation of priority wetlands, limitations imposed by funders, and risks that need to be addressed by the rehabilitation strategy. Furthermore, the evaluation of the Killarney and Kruisfontein wetlands highlighted the need to revise the Water Research Commission's Wetland Management Series, especially those documents or guidelines relating to rehabilitation planning (WET-RehabPlan), interventions (WET-RehabMethods), and monitoring and evaluation (WET-RehabEvaluate).

- Description: The Eastern Cape Karoo region of South Africa typically displays low rainfall and high temperatures, which is particularly concerning considering the shale gas exploration/extraction project proposed recently. Almost 90% of the fracking fluid consists of water and with the Karoo region already classified as a water-stressed region, the increased demand for freshwater for fracking could put further pressure on water resources of the region. By understanding the ecological functioning of the lower trophic levels, likely implications for higher trophic levels can be determined, and ultimately, recommendations for mitigation actions can be made. Here, observations aimed at understanding the dynamics of lower trophic levels are presented, that is, the microalgal biomass and assemblage composition within three characteristic surface waterbodies of the region. In addition, the work focuses on the smaller, more dynamic temporary wetland systems typical of this water-scarce region, with the aim of understanding the significance of single species macrophyte cover in relation to the lower trophic levels. Thirty-three waterbodies were sampled (natural depressions = 13, dams = 9, rivers = 11) during November 2014 (austral spring) and April 2015 (austral autumn). Waterbody physico-chemistry, hydro-morphometry, habitat cover and surrounding land-use, as well as microalgal biomass and assemblage composition within each waterbody type were measured. Thirteen natural depression wetlands were sampled during October 2015, December 2015 and March 2016. Once again, waterbody physico-chemistry, microalgal biomass and assemblage composition were measured. However, in addition, Schoenoplectus decipiens macrophyte cover and microalgal (diatom) species composition were also determined. In general, no significant differences in microalgal biomass between the three main waterbody types of the Eastern Cape Karoo region were found; however, the different waterbody types each displayed distinct microalgal assemblage compositions. Also, Schoenoplectus decipiens cover had negligible effects on microalgal biomass and assemblages in the temporary wetlands investigated here. These results suggest that the generalist nature of species occupying these systems allows them to adapt to the ever-changing conditions typical of this region. Ongoing monitoring initiatives considering impending hydraulic fracturing activities should include a comprehensive species-level diversity census, which could further inform management of any impacts associated with this potential disturbance.

- Description: Ten sampling sites were selected along the Tyhume River corresponding to the upper, mid and lower reaches of the River. In total 48 families were collected during the study. The study observed different types of macroinvertebrate taxa; very low tolerant to pollution (e.g Heptageniidae; Notonemouridae; Perlidae), moderately pollution-tolerant (e.g. Caenidae; Chlorolestidae; Tricorythidae) and very tolerant of polluted conditions (e.g. Chironomidae; Muscidae; Oligochaetae). Both univariate and multivariate analyses were done using PRIMER V6. Above Confluence (ABCON, Site 10) had the highest number (37) of species while Mtloko (MTLOK, Site 2) had the lowest number (24) (Chi-square = 0.87; p < 0.05). The highest number of individuals (4023) was recorded at Macfairlane (MACFA, Site 5) while the lowest number (1240) at Honeydale (HONEY, Site 8) (Chi-square = 0.00; p < 0.05). Margalef’s index indicated Above Confluence (ABCON, Site 10; 4.762), had the highest values of species richness while Mtloko (MTLOK, Site 2; 3.227) had the lowest values (Chi-square = 1; p < 0.05). Pielou's evenness index indicated that Gqumashe (GQUMA, Site 7) had the highest values (0.7137), while Macfairlane (MACFA; Site 5) had the lowest (0.5109) (chi-square = 1; p < 0.05). Shannon-Wiener diversity indices, the highest diversity index values (2.573) of macroinvertebrates was recorded at Honeydale (HONEY, Site 8), and the lowest (1.684) at Macfairlane (MACFA, Site 5) (chi-square = 1; p < 0.05). The ASPT Scores did not differ significantly (P > 0.05) across sites. No significant difference was observed in the ASPT scores across the 10 sites (F = 0.75; df = 9.60; P > 0.05). Site 4 had the highest mean ASPT Scores with mean of 7.6), whereas the lowest. Three biotopes types, namely: stone, vegetation, gravel-sand-mud, stone and vegetation being the dominant biotopes at the 10 sites. The cluster analyses showed that macroinvertebrates were dependent on biotope preference while stone biotope showing greater macroinvertebrate densities. Euclidean distance of site classification with respect to physico-chemical parameters showed very low stress value (0.01) implying that physico-chemical parameters influenced species distribution within each sampling site. The results also showed that good health conditions existed at the most upstream sites than the lower reaches of the river, thus, indicating impacts of pollution within the river.

- Description: In 2011, the South African low birth weight rates varied between 9% and 15.5%, according to different sources. This means that about one out of every ten babies born alive weighed less than 2500g. Furthermore, six of South Africa’s nine provinces, including the Eastern Cape, reported low birth weight rates equal or higher than the national average. These figures raise serious concerns about the health status of infants, their chances of survival and their quality of life, particularly in provinces with a high incidence of low birth weight. Literature has linked the maternal health status to adverse birth outcomes. Statistics from the district office of the Nelson Mandela Bay Health District (NMBHD) indicates that for the fourth quarter of 2015, between 16.65 and 20.9% low birth weight infants were born. However, limited information is available regarding the causes and maternal health status of the mothers of the infants born with adverse birth outcomes in the Nelson Mandela Bay Health District (NMBHD). The objective of the research study is to investigate the associations between maternal health status and birth outcomes in order to identify the major drivers of adverse birth outcomes in NMBHD. The study used a quantitative research approach. In order to enhance the design, the researcher used an explorative, descriptive, cross-sectional, contextual and survey research design. The study was conducted at the regional hospital in Nelson Mandela Bay Health District (NMBHD) and Midwifery Obstetric Units (MOU). The participants were selected using a convenient and purposive sampling technique. A structured, self-administered questionnaire was used as the data collection tool. A statistician assisted with the data analysis. Descriptive and inferential statistics were used. The researcher ensured that ethical considerations were maintained throughout the study to protect the participants. Reliability and validity were also ensured throughout the study. The total sample of the study was 207 and the mean age of the participants was 26,9 years. Hypertension and HIV were the conditions most diagnosed prior to, and during, pregnancy. Most of the delivered infants were females. The findings of the study revealed a significant association between maternal diabetes, maternal hypertension and the infants’ birth weight. Additional findings iv revealed that independent of gestational age, mothers with hypertension are likely to deliver low birth weight (LBW) infants. Antenatal care is of the utmost importance during pregnancy and special attention should be given to the management of hypertension. The researcher developed recommendations for primary health care (PHC) nurses in antenatal clinics (ANC) to address the management of the major maternal drivers of LBW infants in order to decrease and prevent adverse birth outcomes.

- Description: In 2011, the South African low birth weight rates varied between 9% and 15.5%, according to different sources. This means that about one out of every ten babies born alive weighed less than 2500g. Furthermore, six of South Africa’s nine provinces, including the Eastern Cape, reported low birth weight rates equal or higher than the national average. These figures raise serious concerns about the health status of infants, their chances of survival and their quality of life, particularly in provinces with a high incidence of low birth weight. Literature has linked the maternal health status to adverse birth outcomes.

- Description: Teacher attributes such as teacher’s confidence in knowledge are important in the ability to teach. It is further, expected in developing countries that teachers from high socio-economic schools are highly confident in teaching mathematics whilst teachers from low socioeconomic schools are expected to be less confident. Hence, teacher attributes decisions are of great importance in achieving skills development goals. The realisation of the impact teachers’ confidence has on mathematics performance requires an investigation based on multilateral measures of teacher confidence. The purpose of this study is to investigate and analyse the impact of teacher abilities on student’s performance on mathematics in South Africa, this will be realised through an analysis of teacher confidence as the main variable and teacher qualifications, teacher characteristics and socio economic status as controlling variables. The study employed Trends in International Mathematics and Sciences studies (TIMSS) 2011 cross sectional data for South Africa. Descriptive statistics, inferential statistics and the Ordinary Least Squares (OLS) econometric technique were employed in analysing the data. The empirical results revealed that majority of South African teachers rated themselves highly confident but showed no significant impact in the performance of students. This implies that South African teachers who produce poor student’s performance are not open about their lack of confidence in teaching mathematics. However, from the student’s perspective, teacher confidence showed a strong impact on students’ performance in mathematics. The third findings were that, teachers who are happy as educators do not have a significant impact at all. The empirical results also revealed that teachers who felt they wee being allocated more than enough time to teach mathematics showed a strong negative relationship with student performance when compared to teachers who felt otherwise. The findings from the study imply that an open policy should be encouraged in which teachers are encouraged to openly express their views and any shortcomings. This will make it easier to identify the best intervention strategy on helping the teachers. Based on the findings again, it is encouraged that periodic training of mathematical teachers be encouraged. This is likely to boost teacher’s confidence and improve the mathematical results in the country.

- Description: The South African trade union movement faces challenges, that are negatively affecting their role and relevance to their members. It is argued that the use of contract workers in the labour market has significantly reduced the bargaining power of the unions, mainly because the unions are finding it difficult to mobilize contract workers and the workers themselves are believed to be reluctant to join trade unions (Mathekga, 2009). This research project investigated and sought to provide an account of the attitudes and perceptions of the retail workers towards their retail trade union in South Africa. South African Commercial Catering and Allied Workers Union (SACCAWU) is one of the trade unions that is representing these workers in the retail sector and thus also affected by the use of flexible employment arrangements, global work insecurity, and poorly organized labour worldwide. Globally, trade unions are not exempted from the impact of the use flexible labour. Lynch, Pyman, Bailey & Price (2009) pointed out that workers in the European retail sector are employed mainly as contract workers and these workers are rarely involved in trade union activities, consequently the number of unionized workers in the workplace is declining. This context speaks to the changing of attitudes of workers towards their unions. This research study explores the attitudes and perceptions of SACCAWU members towards their union in the retail sector, South Africa. The study was conducted in Port Elizabeth, using in-depth interviews, focus group discussions and observations to ascertain the worker participation and perceptions about their union, SACCAWU. The study seems to confirm most of the labour studies scholars work on disconnection between labour unions and their members, while increasing ‘precarity’ forces workers to stay on unionized despite the negative attitude prevailing.

- Description: The use of traditional medicines by pregnant women is a global concern. Despite limited theoretical evidence on the safety profile of traditional medicines to substantiate their use in pregnancy, expectant mothers are found to be widely using them. Safety concerns related to traditional medicine use in pregnancy include its use during the critical embryonic period, antenatal and intrapartum periods. These medications were associated with complications such as obstructed labour, foetal distress, emergency caesarean sections having to be performed and neonates delivered with low Apgar scorings. Midwives are usually the first and at times the only healthcare providers that come into contact with pregnant women. It was therefore necessary to investigate the midwives’ attitudes towards the use of traditional medicine among pregnant women. The objectives of this study were to: Explore and describe the attitudes of midwives towards the use of traditional medicine in Nelson Mandela Bay. Based on the findings of the study, make recommendations for midwives and nurse managers on how they could inform pregnant women of the benefits and harms of using traditional medicine during pregnancy. The study was conducted between November 2016 and January 2017, using a quantitative approach with an explorative, descriptive, and contextual design having obtained the necessary approval from the university and relevant authorities. The research population was midwives who work in maternity units in Nelson Mandela Bay. Self-administered questionnaires were used to collect data from conveniently sampled participants using set inclusion and exclusion criteria after obtaining informed consent. Data were captured by the researcher on a Microsoft Excel spread sheet and were reduced and analysed with the help of a statistician using the software package IBM SPSS Statistics 24 to ensure efficacy of the results. One hundred and twenty questionnaires were distributed and 89 were returned, yielding a 74% response rate. From the research findings, midwives in the Nelson Mandela Bay do not support the use of traditional medicine during pregnancy. Midwives acknowledged their responsibility to enquire and provide relevant information regarding the use of traditional medicine in pregnancy. Furthermore, midwives associated the use of traditional medicine with womens’ cultural diversity and lack of knowledge about pregnancy and labour. Based on these findings, recommendations for midwives and nurse managers on how they could inform pregnant women of the benefits and harms of using traditional medicine during pregnancy were made. Further recommendations were made for midwifery practice, nursing education and future research. The researcher used a literature control to ensure validation and integrity of the study. Further quality of the study was maintained by observing the principles of reliability and validity. Ethical considerations were guided by the Belmont Report adopting the principles of respect for persons, beneficence, and justice.

Workers and in particular African workers’ rights were severely curtailed. However, following the advent of the Constitution, several employees’ rights and freedoms are now entrenched key amongst them in the right to fair labour practices is enshrined in section 23 (1) of the Constitution. Post 1994, South Africa adopted various new forms of labour legislation, including the Labour Relations Act. This marked the watershed in changing the balance of power away from the employer. The LRA gives form and content to the rights enshrined in the Constitution by establishing substantive and procedural requirements prior to dismissal. Equally important is the guidelines contained in schedule 8 to the LRA which depict an attempt by the legislature to ensure that employees are protected against unfair dismissal. The historical background of the employment relationship stems from the Master and Servant Act. The common law evolved in South Africa from Roman-Dutch and English practices. The common law was shaped against the backdrop of Apartheid modified to some extent through the Wiehahn Commission4 and more recently politically through union and National Economic Development and Labour Council (NEDLAC) involvement regulating labour practices through legislation. In South Africa, the employment relationship is regulated by three main sources of law. These include the Constitution, labour legislation and the law of contract. Besides these sources, South Africa is a member state of the International Labour Organisation.

- Description: South Africa is plagued by socio-economic issues of poverty, inequality and high rates of unemployment. The government of South Africa has as such launched an ambitious plan known as operation PHAKISA which will complement the National Development Plan in addressing the countries aforementioned shortcomings. In the operations first phase, the focus is on growing South Africa’s ocean economy. Within the ocean economy, the growth of aquaculture has been identified as an industry with the potential to create jobs and aid in economic growth of South Africa. Aquaculture, the farming of any aquatic organisms, has been the fastest growing food production sector for the past 50 years. While natural capture fisheries have stagnated in production capacity, aquaculture has grown exponentially in order to feed a global population which is fast approaching nine billion people. However, South Africa’s aquaculture production lags significantly behind other third world countries. The sustainability of aquaculture has frequently been called into question due to the possibility of various detrimental environmental effects it may cause. To further complicate the matter, Climate Change is today an overarching threat to life as we know it, and must be taken into account if we plan to keep growing our populations and economies. As such, if South Africa wants to grow its aquaculture sector, it must be done so in a sustainable manner. This research thus sought to investigate one aspect which may increase the sustainability of aquaculture in South Africa, that being the implementation of renewable energy in the sector. Renewable energy has been identified by the United Nations Intergovernmental Panel on Climate Change as key to mitigating the effects of climate change. In order to aid Renewable Energy (RE) implementation in South Africa’s aquaculture sector, this research aimed to identify the barriers and the drivers to implementing renewable energy within aquaculture. To do this, a literature review was conducted to identify possible barriers and drivers to renewable energy implementation. These were then drafted into an online questionnaire and sent via Email to all the aquaculture organisations in South Africa that could be contacted (n = 195). Respondents were asked to rank the proposed barriers and drivers to renewable energy according to their perceived importance on a Likert Scale. A total of 18 responses could be analysed with descriptive statistics. Further, three structured interviews were conducted with members of South African aquaculture organisations who had implemented some form of Renewable Energy Technology (RET). These interviews provided in-depth insights into the importance of the various proposed barriers and drivers. The results revealed the most important barriers to RE implementation were: High Initial investments, Utility monopoly of production, Lack of RE experts on a governmental level, Lack of incentives/subsidies from government, Lack of legal framework for Independent Power Producers and Power Purchase Agreements, and Diseconomy of scale respectively. The most important drivers to RE implementation were ranked as: Long term cost benefits, Reduction in cost of RETs, Innovation / advancement of RETS, Incentives or subsidies to implement renewable energy, Adequate legal framework and legislation for Power Purchase Agreement and Preference for environmentally-friendly electricity generation. Importantly, it was found that barriers and drivers are dependent on the type of RE being implemented. A Photo Voltaic (Solar Power) system will not necessarily experience the same barriers or drivers that a Wave Energy Converter system would. In order to drive investment in RE and remove the barriers that may be preventing its implementation in aquaculture, policy will have to be adapted. Particularly in terms of legislation around Power Purchase Agreements. Further, by providing subsidies for RE implementation, it is possible to sustainably grow South Africa’s aquaculture industry.

The aim of this study was to identify any barriers to the movement of picking and packing operators within 6 distribution facilities throughout South Africa using a time and motion analysis. A pilot study was initially conducted to choose the stopwatch application for Android® devices and to ensure reliability of the tools utilised. The motions during the processes of fulfilling an order were identified during the case picking, bulk picking and packing processes by direct observation of operators. The direct observation was performed using a stopwatch application for Android® devices and a tool on Microsoft Excel®. The data was analysed using Microsoft Excel®, using a student’s T-test and an analysis of variance (ANOVA) approach to identify similarities and differences between the facilities. The data was further analysed using a descriptive statistics approach to identify the common barriers amongst the distribution centres. Thereafter, the data was analysed by identifying a value-quotient. The value-quotient was used to identify how much time was spent on value-adding activities with each facility. The observation of the operators was done randomly at each facility to avoid subjectivity and bias. Results: The pilot study identified which stopwatch application was to be utilised. The pilot study aided to improve upon the design of the data collection tool used for the transcribing of the timing operation. The student’s T-test and ANOVA revealed that there were statistically significant differences in case picking amongst facilities, namely using the radio frequency identification devices (RFID), picking and transfer of stock. In the bulk picking process, there was a statistically significant difference amongst the facilities, namely using the RFID, pick and transfer of stock. In the packing process there was a statistically significant difference amongst the facilities in the packing process. The analysis of barriers within the distribution centres revealed that the 16 common barriers amongst the picking processes at the facilities included raising the platform, waiting for colleagues to depart an aisle, RFID malfunctions and answering their phones. No common barriers during the packing process was identified. The value-quotient revealed that most of the facilities spent more than 50 percent of their time on value-adding activities during the case picking, bulk picking and packing processes. A time and motion analysis proved to be an effective method to identify similarities and barriers between the six facilities. It was recommended to investigate a few of the basic operations to improve upon, as well as the possibility of implementing a barcoded system to the stock.

- Description: Disease mapping and spatial statistics have become an important part of modern day statistics and have increased in popularity as the methods and techniques have evolved. The application of disease mapping is not only confined to the analysis of diseases as other applications of disease mapping can be found in Econometric and financial disciplines. This thesis will consider two data sets. These are the Georgia oral cancer 2004 data set and the South African acute pericarditis 2014 data set. The Georgia data set will be used to assess the hyperprior sensitivity of the precision for the uncorrelated heterogeneity and correlated heterogeneity components in a convolution model. The correlated heterogeneity will be modelled by a conditional autoregressive prior distribution and the uncorrelated heterogeneity will be modelled with a zero mean Gaussian prior distribution. The sensitivity analysis will be performed using three models with conjugate, Jeffreys' and a fixed parameter prior for the hyperprior distribution of the precision for the uncorrelated heterogeneity component. A simulation study will be done to compare four prior distributions which will be the conjugate, Jeffreys', probability matching and divergence priors. The three models will be fitted in WinBUGS® using a Bayesian approach. The results of the three models will be in the form of disease maps, figures and tables. The results show that the hyperprior of the precision for the uncorrelated heterogeneity and correlated heterogeneity components are sensitive to changes and will result in different results depending on the specification of the hyperprior distribution of the precision for the two components in the model. The South African data set will be used to examine whether there is a difference between the proper conditional autoregressive prior and intrinsic conditional autoregressive prior for the correlated heterogeneity component in a convolution model. Two models will be fitted in WinBUGS® for this comparison. Both the hyperpriors of the precision for the uncorrelated heterogeneity and correlated heterogeneity components will be modelled using a Jeffreys' prior distribution. The results show that there is no significant difference between the results of the model with a proper conditional autoregressive prior and intrinsic conditional autoregressive prior for the South African data, although there are a few disadvantages of using a proper conditional autoregressive prior for the correlated heterogeneity which will be stated in the conclusion.

- Description: My thesis is a novella in flash, written as political crime fiction. It is set in contemporary South Africa and tells the story of Rafau Lekopo, a teacher from a little township called Dikgohlong, whose life is changed forever after he finds his wife and the mayor in bed and shoots them both dead. The information contained within the dead mayor's notebook proves to be explosive, showing that the mayor is far more than he seems, and that he is in fact in the employ of a foreign intelligence service. After his release from prison, the embittered Lekopo sets about his revenge against powerful men who abuse their political power. He takes refuge in Lesotho, masterminds a series of heists, car-hijackings and human trafficking, and expands his syndication back in South Africa. Using the contacts and information from the mayor's notebook, he manipulates the Lesotho government into a diplomatic feud with South Africa which treatens to escalate into a military conflict.

- Description: The emergence of distributed leadership theory encourages multiple involvement of individuals in leadership of the school, regardless of their leadership positions (Spillane, 2006). The manifestation of teacher leadership through distributed leadership theory grants opportunities to teachers to enact leadership roles. This study explored how the notion of teacher leadership is understood, the leadership roles existing for the beginner teachers, and the constraining and enabling factors to the practice of teacher leadership in a rural combined school in Ohangwena region, in Namibia. The study is a formative intervention adopting a case study approach located in a critical paradigm since it aimed to bring changes in the activity system of the beginner teachers. The data were collected from ten participants: four beginner teachers, four experienced teachers, the principal and the Head of Department. The data were generated using the following techniques: document analysis, interview, questionnaires, observation and Change Laboratory workshops. The data were analysed thematically using second generation of Cultural Historical Activity Theory (CHAT) and Grant’s (2006, 2008, 2010) Teacher Leadership Model. The findings revealed that there were different understandings of the concept of teacher leadership. It was viewed as participation, influence, motivation and mentoring. It was also revealed that beginner teachers practiced leadership roles across the four zones of Grant’s (2006, 2008, 2010) Teacher Leadership Model, but to various extents. A high participation was noted in zone one within the classroom and zone two in curricular and extra-curricular activities and minimal participation was reported in zone three within the whole school development and zone four beyond the school into the community. Teacher leadership in the case study school was constrained by several factors, including teachers’ reluctance to lead, cultural beliefs, top-down leadership structure and lack of experience. Due to the minimal participation of beginner teachers in zone three and four, the findings suggested that the school should foster a collaborative culture, establish induction and mentoring committees in the school and encourage beginner teachers to take up leadership roles by providing opportunities for them to lead through delegation. In a series of Change Laboratory workshops (CLW) the principal and the Head of Department took up the responsibility of providing leadership training to the teachers to enable them to assume leadership roles in the school. In addition, participants agreed to establish induction and mentoring committees in the school to provide guidance and assistance to teacher leaders.

- Description: In this thesis we consider the problem of simultaneously approximating elements of a set B C X by a single element of a set K C X. This type of a problem arises when the element to be approximated is not known precisely but is known to belong to a set.Thus, best simultaneous approximation is a natural generalization of best approximation which has been studied extensively. The theory of best simultaneous approximation has been studied by many authors, see for example [4], [8], [25], [28], [26] and [12] to name but a few.

- Description: Macrofungi represent an untapped source of natural bioactive compounds for various diseases, which have been targeted as potential therapeutic agents. The medicinal uses of macrofungi discovered to date include anticancer, antidiabetic, antioxidant, antimicrobial, and immunomodulatory properties. The knowledge regarding the medicinal uses of macrofungi in Africa is limited; however, it is believed that Africa may contain a large number of unidentified species of macrofungi. The objectives of this study were to: (i) screen the macrofungal extracts for antimicrobial activity against microorganisms responsible for respiratory diseases (e.g. Pseudomonas aeruginosa, Klebsiella pneumoniae, Streptococcus pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Mycobacterium tuberculosis, HIV-1), (ii) determine the effect of macrofungal extracts on bacterial morphology, (iii) investigate the cytotoxicity of macrofungal extracts against human lung carcinoma cells, and to elucidate the mechanism/s of action of cytotoxicity/anticancer activity. In vitro bioassays for antimicrobial activity included: ρ-iodonitrotetrazolium chloride assays and microplate alamar blue assay (MABA), while the HIV-1 reverse transcriptase colorimetric ELISA and HIV-1 protease fluorometric assay kits were used for anti-HIV activity. Cytotoxicity of the macrofungal species against A549 lung cancer cell line was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, and the IC50 values determined for the most cytotoxic macrofungal spp. The mechanism of cytotoxicity was investigated by cell cycle analysis and fluorescent staining to observe morphological and biochemical changes (i.e. acridine orange, caspase activation). Ethanol extracts of Amanita foetidissima, Gymnopilus junonius, Pisolithus tinctorius, Fomitopsis lilacinogilva, Stereum hirsutum and Pycnoporus sanguineus showed higher antimicrobial activity against the Gram-positive bacteria than aqueous extracts, with S. pneumoniae being the most susceptible. The ethanol extracts of Agaricus campestris, Chlorophyllum molybdites, Gymnopilus penetrans, Pseudophaeolus baudonii and Laetiporus sulphureus exhibited anti-TB (tuberculosis) activity with minimum inhibitory concentrations (MICs) ranging between 500-1,000 μg/mL. C. molybdites ethanol extract inhibited HIV-1 protease activity (IC50: 49.7 μg/mL). The macrofungal extracts did not inhibit HIV-1 reverse transcriptase activity. Ethanol extracts of F. lilacinogilva, G. junonius, P. sanguineus and the aqueous extract iv of P. baudonii were cytotoxic against A549 lung cancer cells at IC50 values of 69.2±3.6, 57±5, 7.4±1.1 and 53.6±1.1 μg/mL, respectively. Cell cycle arrest was observed in the G2 phase for both P. sanguineus and P. baudonii, and G2/M and early M phases for G. junonius and F. lilacinogilva, respectively. Apoptosis induced by macrofungal extracts was confirmed by fluorescent staining. Morphological and biochemical changes included chromatin condensation, membrane blebbing, loss of cytoskeletal structure, caspase activation and phosphatidylserine translocation. This study demonstrates the biological activities of selected macrofungal extracts and their potential mechanisms of action. Isolation and identification of active compounds require further analysis.
