- Description: Introduction: The marine environment is rich in the biodiversity of medically significant invertebrate species such as sponges, ascidians, molluscs and bryozoans. Such a diverse environment is a potential source of a great variety of secondary metabolite production. Research in marine natural product discovery is gaining ground with the development of new therapeutic drugs of antimicrobial potential. Aim: This study seeks to evaluate, and identify bioactive compounds obtained from marine invertebrates collected from Phillip’s Reef in Algoa Bay. Methodology: Marine invertebrates were collected from the Phillip’s Reef in Algoa Bay, Port Elizabeth, at a depth of 12 m and the physichochemical parameters at the site of sample collection were recorded onsite. Sampling was done once over the four seasons in South Africa. Sections of each specimen were sent for identification, and extraction of compounds was done using organic solvents [methanol (95percent), hexane (95percent), petroleum ether (95percent), chloroform (95percent) and ethyl acetate (95percent)]. A ratio of 95percent the respective solvents was achieved by the following (1:19), organic solvent combinations [dichloromethane: methanol (1:1), hexane: chloroform: methanol (1:2:1)] and aqueous solution of water. Solvent optimization was done by measuring the absorbance of S. aureus (ATCC 49476) in Mueller Hinton Broth containing crude extracts at 600 nm. The appropriate solvent was then selected for further extraction of bioactive compounds from the specimens. Antimicrobial activity of the crude extracts was evaluated using the standard agar well diffusion method on test pathogens, namely, methicillin-resistant Staphylococcus aureus (ATCC 49476), clostridium difficile (ATCC 9689), Pseudomonas aeruginosa (ATCC 10145), Candida albicans (ATCC 10231) and Aspergillus fumigatus (ATCC 204305). Different concentrations of the crude extracts were used [100percent, 80percent, 60percent, 40percent and 30percent (v:v)] and the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were determined. Selected bioactive crude extracts were further evaluated for phytochemicals before being purified by subjecting them to Sephadex-G75 column chromatography, using 75percent ethyl acetate as the mobile phase. Bioactive crude extracts fractions obtained following column chromatography were subjected to Electron Spray Ionization Time of Flight (ESI-TOF) analysis using The Bruker Daltonics maXis compact ESI Quadrupole TOF instrument to detect and identify compounds present. Peak identification was done using the blast software contained in Open Chrom Community Edition (Alder), open source software for chromatography and mass spectrometry spectrum analysis. Results: Sixty-seven different marine invertebrate species were collected over the 4 seasons. A mean temperature of 17.35oC ± 2.06 was recorded over all four seasons with the Autumn exhibiting the highest temperature (20oC). Salinity readings obtained ranged between 35.12 psu and 35.27 psu. A stable mean pH range of 8.08–8.78 was also recorded across all four seasons. Salinity and pH readings conformed to the standards set by the South African Water Quality Guidelines. The Spring season exhibited the highest turbidity of 2.97 NTU compared to other seasons. Ethyl acetate and dichloromethane: methanol (1:1) extracts yielded the best inhibitory results. Approximately 60percent (4/67) of the marine invertebrate specimens showed bioactivity against some of the test pathogens. Both ethyl acetate and dichloromethane methanol crude extracts of S14 and S34 showed a broad spectrum of antimicrobial activity against both bacteria and fungi. The C6 ethyl acetate crude extracts were highly active against MRSA, as inhibition zones of 45 mm were observed. MIC at 30percent concentrations was observed for very few crude extracts against the five pathogens. Sixty-three ethyl acetate crude extracts contained phytochemicals while only 35 dichloromethane: methanol crude extracts contained phytochemicals. Neither ethyl acetate and dichloromethane: methanol crude extracts of S34 (Psammopsinia sp. 1) that were biologically active had any phytochemicals. Canadine, Ginkolide A, Apigenin, Amygdalin, 10-hydroxy-Camptothecin, Catechin, Beta-Peltatin and 6 Ethoxy-3(4'-hydroxyphenyl)-4-methylcoumarin were identified in the crude extracts. Conclusion: Marine invertebrate species located at Phillip’s Reef produce compounds with antimicrobial potential. These compounds are biologically active against human pathogenic microorganisms. The best solvent to use for the extraction of these biologically significant metabolites is ethyl acetate, as this study achieved outstanding results from ethyl acetate crude extracts in the form of high zones of inhibition, for example the sponge Ectyonopsis flabellate, which exhibited mean inhibition zones of 45 mm against Aspergillus fumigatus. Similar bioactivity was also observed with Tedania (Tedania) Stylonychaeta against Methicillin Resistant Staphylococcus aureus. This is the first study done on some of the marine sponges and ascidians in the Phillip’s Reef, and therefore further evaluation of the purified compounds is necessary in order to obtain the identity of the pure compounds and possibly determine the mechanism of action, and synthesize structural analogues for further studies.

- Description: Tulbaghia violacea is a plant that is commonly used for traditional medicine in the Eastern Cape and Kwa-Zulu Natal Provinces of South Africa for treatment of ailments, such as fever, colds, asthma, tuberculosis, stomach-ache and cancer of the oesophagus. This plant has been found to be rich in sulfur-containing compounds that may display good potential as devulcanizing agents. Commonly used chemical devulcanizing agents are disulfides, such as diphenyl disulfide. These have been found to be relatively expensive compared to other methods of devulcanization. This study aimed to show that the sulfur- containing compounds extracted from the readily available Tulbaghia violacea plant can be used as devulcanizing agents. The presence of sulfur-containing compounds in the plant was positively identified by qualitative phytochemical analysis. Extraction of sulfur-containing compounds from the bulk plant material was successfully performed using the Soxhlet extraction method with a 2% 2-propanol in n-hexane solvent mixture. There was a positive identification of sulfur compounds in the crude extracts of the bulbs, roots and leaves. Diallyl disulfides (DADS) extracted from the plant were successfully quantified using normal phase high-performance liquid chromatography (HPLC). The results showed that in a bulb crude extract of 9.89 mg/mL concentration, there was 7.74X10-2 mg/mL concentration of DADS. In the roots crude extract of 10.26 mg/mL concentration, there was 2.93X10-2 mg/mL concentration of DADS; and in leaves crude extract of 10.47 mg/mL concentration, there was 3.69X10-2 mg/mL concentration of DADS. The crude extracts were evaluated for their effectiveness as devulcanizing agents by reacting them with vulcanized 2,3-dimethyl-2-butene (TME), which was used as a model compound. A reverse phase HPLC method was used to identify crosslink species formed during vulcanization, and to monitor the broken crosslinks during devulcanization. It was observed that the di- and polysulfidic crosslinked vulcanized model compound species were not present in the devulcanized product. Furthermore monosulfidic crosslink species, a common end species of devulcanization, were observed to increase in concentration from the HPLC chromatograms. It was observed that the extracts from the bulbs and leaves of Tulbaghia violacea were more effective than the extract from the roots when applied to the vulcanized model compound. This study demonstrates that Tulbaghia violacea can be used as alternatives to petroleum-derived chemicals as devulcanizing agents.

- Description: The Facilities Management (FM) profession in South Africa needs to start recognising and acknowledging the importance of formal education amongst the population. The question of FM being a career normally receives shallow responses; and it sometimes leads to a contradiction. The FM profession seems to be taking an ‘as it is’ approach, when it comes to the establishment of an education agenda; since there is no clear evidence regarding alignment and transition from high school to tertiary level, and then to the workplace. The level of awareness plays a significant role in all elements of FM practice. Even at the present moment, FM is still not a career of choice, meaning that anyone can be a facilities manager. There are parts of South Africa where the population is unaware of FM. Some had never heard about it at all. It was important to establish the level of awareness: with the intention of developing a critical awareness of FM as a career path amongst high school learners and teachers in the Soutpansberg West Circuit, in order to inform them of a possible career choice in FM. In this study, a mixed-model research methodology was used, which combines both qualitative and quantitative research approaches. A population was identified from which a sample of 14 high schools, 87 high school teachers and 2 299 high school learners was drawn. A ‘fit for purpose’ questionnaire was distributed to the participants. The data were collected by means of a survey. It focused on a survey; and it used a questionnaire that was composed of multiple closed-ended or quantitative-type items, as well as several open-ended or qualitative-type items. Thematic analysis was used for the open-ended questions. This study has successfully managed to determine the awareness levels of high school learners and teachers relating to FM, the need for FM awareness in high schools; and whether there were high school learners who wished to become facilities managers in the future. FM companies, tertiary institutions, and high schools must collaborate in the development of the FM career-guidance programme, in order to increase awareness amongst the teachers and learners. There were students who indicated that they were interested in FM as their career of choice.

- Description: Background:Context-specific factors influence adherence to antiretroviral therapy (ART) among pregnant womenliving with HIV. Gaps exist in the understanding of the reasons for the variable outcomes of the prevention ofmother-to-child transmission (PMTCT) programme at the health facility level in South Africa. This study examinedadherence levels and reasons for non-adherence during pregnancy in a cohort of parturient women enrolled in thePMTCT programme in the Eastern Cape, South Africa.Methods:This was a mixed-methods study involving 1709 parturient women in the Eastern Cape, South Africa. Weconducted a multi-centre retrospective analysis of the mother-infant pair in the PMTCT electronic database in 2016.Semi-structured interviews of purposively selected parturient women with self-reported poor adherence (n= 177)were conducted to gain understanding of the main barriers to adherence. Binary logistic regression was used todetermine the independent predictors of ART non-adherence.Results:A high proportion (69.0%) of women reported perfect adherence. In the logistic regression analysis, afteradjusting for confounding factors, marital status, cigarette smoking, alcohol use and non-disclosure to a family memberwere the independent predictors of non-adherence. Analysis of the qualitative data revealed that drug-related side-effects, being away from home, forgetfulness, non-disclosure, stigma and work-related demand were among the mainreasons for non-adherence to ART.Conclusions:Non-adherence to the antiretroviral therapy among pregnant women in this setting is associated withlifestyle behaviours, HIV-related stigma and ART side-effects. In order to eliminate mother-to-child transmission of HIV,clinicians need to screen for these factors at every antenatal clinic visit.Keywords:Adherence, Non-adherence, HIV, Antiretroviral therapy, Elimination of mother-to-child transmission,Prevention of mother-to-child transmission, Stigma, South Africa

- Description: Among the requirements to achieve effective ecological restoration on a landscape scale are a scientific underpinning, strong adaptive management and the setting of realistic endpoints. Efficacy and success depend on a complex interplay of factors of both local and regional influence. Biome-wide restoration experiments are rare, but valuable for evaluating efficacy of different protocols according to local context. The Thicket-wide Plot (TWP) experiment was initiated by the Subtropical Thicket Restoration Programme to inform landscape-scale ecological restoration of degraded Portulacaria afra (spekboom)-rich Subtropical Thicket. Thirteen different planting treatments of Portulacaria afra (spekboom) truncheons were planted as replicated rows on 0.25 ha fenced plots across the distribution range of spekboom-rich thicket habitat to better establish effective restoration protocols. I used a rule-based learning ensemble algorithm to evaluate 60 different predictors that potentially impact effective restoration, covering a range of climatic, topographic, edaphic, ecological and management related factors observed at 227 of these TWP plots. Percentage survivorship and aboveground biomass carbon sequestration rate (ABCsr) were taken as proxies for efficacy derived from subsequent monitoring data gathered 2 - 5 years after establishment, and a new allometric model I developed for spekboom. I found herbivory and identification of target habitat the two most important predictors of restoration efficacy, both well within the control of the practitioner. Highest survivorship and ABCsr were associated with larger truncheons planted deeper. The only exception to this pattern was found amongst the two smallest size truncheon categories. The application of external rooting hormone or watering treatment to truncheons were found of no significance to effective restoration, while all the pruned treatments were, in association with lesser planting depth, found to be significantly less effective than untreated truncheons planted deeper. When the restoration protocol is optimal (largest truncheons planted deepest in target habitats and protected from herbivory), my results show higher annual carbon sequestration rates (1.46 - 3.7 t C ha−1 yr−1 in aboveground biomass) than most older restoration sites that have been identified as benchmarks of success. In order to project ABC endpoints, I generated 40 new species-specific allometric models and used them to estimate biomass and carbon of intact and degraded stands on five sites spread out across the region. The highest AGC for stands in both intact and degraded states were estimated at 42.96 t Cha−1 and 12.98 t C ha−1 respectively, and the lowest at 26.32 t C ha−1 and 2.52 t C ha−1. Large canopy dominant (LCD) species contributed the largest AGC portion at three intact stands. The second largest portion was recorded for spekboom. The difference between paired stands on each sample site ranged between 23.8 and 32.8 t C ha−1, which provide a realistic target for biome-wide restoration that, when adopted together with current protocols, may be reached within three decades of inception.

- Description: Engineering is of vital importance for humankind. Engineering combines the fields of mathematics and science, including engineering science and technology, in order to solve problems in the real world and in order to improve the society and economies of countries. It includes the ability to implement ideas in a cost effective and practical manner. Some of these solutions may include sustainability, needs of society, necessary risks and protection of the environment. Engineers develop ideas by using production of technology in order to improve the living of humankind. This includes designing and manufacturing different products based on customer needs and expectations. Although a field in engineering is largely a male-dominated career, women are becoming more interested in this career, compared to a few years ago. The problem remains that female students are still in the minority compared to their male counterparts studying engineering. Therefore, universities need to find solutions to attract female students towards engineering. There are various reasons why female students choose to study engineering, which include different influences, encouragements and their perception towards the Faculty and the academic staff. Thus, the purpose of the research study is to identify the reasons for both genders, currently studying engineering at Nelson Mandela University, formally known as Nelson Mandela Metropolitan University (NMMU), why they chose to study engineering, what influenced their studies, their encouragements or discouragements and overall perception and experience while studying engineering. The main focus will be on female students. This research study was an exploratory, mixed method study, which contains literature studies, surveys and cross-sectional studies. A literature study was compiled by using secondary sources in order to identify the importance of engineering internationally and within South Africa, women in the workplace and female students studying towards engineering. The empirical study, which consisted of a survey, was compiled and distributed to all Nelson Mandela University undergraduate students studying towards an engineering qualification. Respondents were asked various questions regarding pre-studies and their perceptions and experiences during their studies. This includes their experience with the academic staff and the Faculty of Engineering in general. For the analysis of the data, both Descriptive and Inferential Statistical methods were used. Some of the findings from the research study include that both genders develop an interest for engineering at a young age (between ages 13 – 18). Therefore, an interest is developed during high school level. Both genders choose to study engineering for the same reasons. The interest for choosing a career for both genders was triggered by a qualified engineer’s influence. During high school, female students take part in science, mathematics and engineering programmes and participate in competitions or contests. Both gender’s science, mathematics and engineering abilities increased since they started their studies at a higher education institution. From the findings, both genders indicated that they have a high level of interest in engineering, they are satisfied with their choice of engineering field and they are committed to complete their engineering qualification. Both genders are confident that they will find employment in engineering that pays well. Female students believe that they are better at problem solving activities, they are more committed to their studies, they work better with other people and they are more confident in their engineering abilities compared to the male counterparts. The findings also include that during their studies, both genders receive encouragement from various factors, but the significant source of encouragement for both genders are their mothers and employment opportunities. Whereas the most significant source of discouragement for both genders are their grades or academic performance and the amount of time required for engineering. Both genders receive equal quality in lecturing throughout their studies and the academic staff do not treat female students different from male students. It is also significant that female students receive support from the Faculty of Engineering. Female students will definitely encourage other females to study towards a field in engineering and find the academic staff approachable. Academic staff does give regular feedback to students regarding their academic performance. Therefore both genders know at all-time their academic performance and therefore will be able to improve their results. There are not enough female lecturers within the Engineering Department. Female lecturers serve as role models for female students. Therefore, the University’s management team needs to investigate this matter. The research study concluded with recommendations and considerations, contribution towards the body of knowledge, future research and the limitations of the study. Furthermore, the study offers an understanding of engineering students at Nelson Mandela University, which includes their current overall experience during their studies. The treatise will therefore assist the readers and especially Nelson Mandela University to attract and retain female students by addressing their challenges they experience during their studies.

- Description: Background: There is a requirement to provide proper and safe quality service to patients, hence a view from patients was deemed important as it can help the hospital to improve services rendered to them. There were two Provincial assessments done on National Core Standards in Postmasburg Hospital (overall scores were 32percent in 2013 and 48percent in 2014) and on both occasions, the Hospital failed to comply with the assessments and the implication were a suspected negative impact on the Hospital service delivery. The repercussions could be that the hospital might not be certified or not funded through National Health Insurance following a national assessment if the status quo remains. Aim: The aim of the study was to describe the factors affecting patients’ perceptions of service delivery in order to inform health policy decisions to improve service delivery. Methodology: A quantitative descriptive design was used to collect data on 133 adult patients admitted for a minimum of three days in the different hospital wards. Participants were administered a structured pre-tested questionnaire to collect data relating to their employment status, the number of hospital admissions and the reason for hospital admission. Results: About 41.4percent of participants were neutral or not sure whether the nurses/doctors came often to the ward where they were admitted. The majority (51.9percent) were neutral or not sure whether the quality of food in the hospital was good; 53.4percent expressed uncertainty concerning the adequacy of benches/chairs in the hospital for patients to sit while waiting to be seen by the health worker; and 55.6percent participants were neural or not sure whether the ward/room had enough space for consulting. Asked whether the hospital was user-friendly to disabled persons, 53.4percent participants were not sure. About 43.6percent participants expressed uncertainty regarding the registration satisfactory nature of the procedures in the hospital; the water cleanliness for patients in the hospital (42.1percent); whether their privacy was respected by all the staff within the hospital (51.9percent); permission to be examined and treated (51.1percent); the nurse/doctor who treated them being polite (53.4percent); and the nurse/doctor who treated them being able to answer all their questions about their illness (56.8percent). On whether they will visit the hospital again, 49.6percent participants were uncertain. The majority (69.7percent) agreed that all prescribed medicine was available in the hospital; the staff explained to them on how to use the medicine/pills (67percent); and they were told on how to store their pills/medication (47percent). Gender, education and employment status of the participants affect exactly one dimension each. Females, those with secondary education and employed were more satisfied on the respective dimensions. Conclusion: Patient involvement is an essential feature in healthcare services. Patients influence outcome quality through compliance, defining the right symptoms and physically experiencing treatment. Patient perceptions and satisfaction with service delivery is a multi-dimensional concept that should be studied by operationalising it within its context. Consequently, a conceptual model to understand and measure patient perception and satisfaction of service delivery and care quality in hospital health care services is proposed.

- Description: This study is a quantitative study done in selected schools on teachers’ attitudes towards the implementation of inclusive education. Despite efforts to ensure quality education for all learners through inclusive education in South Africa, indications are that many learners, especially those who experience barriers to learning, are still excluded from full access to quality and equitable education opportunities in mainstream schools. Research has shown that the success of inclusive education depends upon teachers’ attitudes. It also shows that attitudes can hinder the progress of the implementation of inclusive education. The paper draws on White Paper 6 which speaks to inclusion of children with disabilities in schools. As the legislative and policy framework for the implementation of inclusive education, White Paper 6 states that “a public school must admit learners and serve their educational requirements without unfairly discriminating in any way”. The study is framed by Ajzen’s theory of planned behaviour, which suggests that an attitude towards behaviour is influenced by past experiences, previous knowledge and newly acquired knowledge. The study reflects findings from a questionnaire circulated to 75 teachers at three selected high schools, using descriptive statistics to analyse the data. Findings showed that there is no relationship between attitudes based on factors, including class size, years of experience, inadequate resource, and lack of adequate training but the main negative influence was found to be lack of support in implementing inclusive education. The conclusion is that there is no relationship between attitudes and the factors identified except lack of support. This research concludes with recommendations to address teachers’ attitudes in order to facilitate the inclusion of learners with special needs in the classroom.

- Description: Career advancement is viewed as an important element of job satisfaction and employee retention, however the gender differences observed in the workplace globally mean that there is gender inequality even in career growth. With South Africa’s long history of discrimination, career advancement disparities are observed along racial and gender lines. The current study’s focus is on the factors affecting the career advancement of a group of black women working for a selected manufacturing firm in Gauteng. The study highlights the importance of both the individual and the organisation in driving career advancement and asserts that there are self-driven and employer-driven factors affecting the career growth of black women employed by the selected firm. The primary objective of this study was to investigate and analyse factors affecting the career advancement of South African black African women (hereafter referred to as black women) employed by the manufacturing company. After a comprehensive literature study, three self-driven factors (pre-career choices, career capital development and attitude towards gender discrimination) and three employer-driven factors (mentorship opportunities, organisational leadership and organisational culture) were identified as factors affecting career advancement. These were subsequently empirically tested. A quantitative research paradigm was adopted for this study. The sample chosen was the entire population of black women employed by the business in question. Using the survey research method, a structured questionnaire was distributed resulting in an 85% response rate. Cronbach’s alpha was employed to test the reliability or internal consistency of the research instruments, resulting in the minimum acceptable level of 0.70 being met. The data collected were subjected to statistical analyses using simple regression analysis, one-factor Anova and descriptive statistics. The simple regression analysis revealed that pre-career choices had a statistically significant positive influence on career advancement. Furthermore, the findings suggest a link between education and employability, as the majority of the respondents (53%) possessed tertiary qualifications. Although no empirical evidence was found to support the influence of the other five factors on career advancement, the use of descriptive statistics revealed clear differences brought about by variations in education, such as the significantly higher levels of career capital for respondents with post-graduate qualifications in comparison to the total sample. The findings of this study informed the recommendations made to promote the career advancement of the black women employed by the selected firm. These were recommendations for individuals to enhance their career capital through education and the pursuit of career goals, and for the organisation to support career development with a conducive environment that values all employees and affords them equal opportunities for growth.

- Description: Among the threats, barriers and challenges impeding access to health services in developing countries, Primary Healthcare Supervision was reported as a critical link with complex interventions that are implemented in different ways (Bosch-Capblanch & Garner, 2008:369). Among the objectives of the KwaZulu-Natal Department of Health Policy for PHC Supervision; are increasing the PHC Supervision rate from 60 percent to 85 percent; improvement of community participation and inter-sectoral collaboration to achieve improved health services in all health clinics in the Province of KwaZuluNatal (KZN Department of Health PHC Supervision Policy, 2010:9). However, currently there is no policy guiding the PHC Supervision processes in the province albeit an adapted policy document from the National Health Department and set of supervision tools are used to date. It is therefore critical to examine the strength and weaknesses of the current adapted guidelines for PHC Supervision processes including the reasons for the current low PHC Supervision rate in the province. , Thesis (MPH) -- University of Fort Hare, 2018

- Description: Aim: South Africa is faced with the major challenge of ensuring and sustaining the quality of services, including preventing and managing side- effects, and improving drug adherence, which are all critical, for the success of a comprehensive HIV programme. The aim of this study was to examine the underlying contributing factors to antiretroviral treatment adherence among HIV positive patients attending primary health care facilities in East London. Methods: This was a descriptive cross-sectional study involving 371 HIV positive patients on antiretroviral treatment in xx primary health care facilities in East London, South Africa. The study utilized a self- designed structured questionnaire with both open- ended and closed ended questions, divided into socio-demographic, socio- economic, level of understanding and knowledge on HIV, quality of care and waiting times. Results: About 64 percent of the participants had a good knowledge of HIV, 25 percent had an average knowledge with few participants having poor knowledge of HIV (11 percent). Majority (92.2 percent) were counselled before starting ARVs treatment. Majority of participants (70.7 percent) do have money for transport to come to the clinic, while 53.1 percent experienced side effects. The majority (70 percent) of the participants were non-adherents. Concerning viral load distribution, 52 percent were undetectable, 26 percent unsuppressed and 22 percent suppressed. Marital status (married) (p=0.005), having no formal education (p=0.035), being Christian (p=0.007), alcohol consumption (p= 0.021) and viral load suppression had significant association with non-adherence to ARV treatment among participants. After adjusting for confounders, only non-Christians and unsuppressed viral loads were the independent predictors of non-adherence. Conclusion: The main contributing factors to ART non-adherence among participants on ARVs were marital status, level of education, religion, and Christians were more adherent to the treatment than non-Christians. Alcohol consumption also contributed to non-adherence and viral load. Adherence counseling should be done on each and every visit to remind the participants on the importance of taking their treatment. These factors need to be addressed to improve adherence to the treatment, decrease the virus in the blood (viral load) and improve their health in general.

- Description: Tax morale is the intrinsic motivation to pay taxes that arises either from a belief that one should contribute towards society by paying taxes or from a moral obligation to pay taxes. The goals of this thesis were to identify the various factors that influence tax morale in a country and use these factors in order to attempt to determine whether tax morale in South Africa has improved or deteriorated over the years. A further goal of this thesis was to identify strategies that could be implemented by a country in order to improve the tax morale of its citizens. The period covered by this thesis is between the years 2000 and 2015. The factors that have an effect on tax morale were identified by a review of the literature. It was found that a number of factors appear to have an impact on tax morale, but certain of these factors are incapable of being directly influenced by tax administrations. With regard to South Africa, it was found that a number of factors affecting tax morale appear to have improved over the years, while others had deteriorated. However, overall it appeared that tax morale in South Africa had deteriorated. With regard to strategies that could be used to improve tax morale, a number were identified by reviewing the literature and include strategies implemented in certain countries, as well as those discussed by scholars. Ii was found that South Africa had implemented a number of the strategies aimed at improving tax morale in its own tax system, but the manner in which some of them were implemented could have been improved. Furthermore, a number of strategies were identified that South Africa has not yet implemented and thus should look to attempting to implement these strategies to improve tax morale.

- Description: During the period ranging from 2011 to 2013, Zululand Health District reported tuberculosis (TB) related mortality cases above the WHO’s norm of 10 percent. This raised concerns because TB is curable even if the person is HIV positive. The overall performance of TB programme in South Africa concealed the actual problem of TB related mortality in the country and most particularly in Zululand Health District. The aim of the study was to examine factors contributing to TB mortality, and the extent of TB related mortality in Zululand Health District. A retrospective, descriptive study was conducted to review records of data on the electronic TB register at the district level in order to ascertain the relationship between TB mortality and the contributory factors associated with TB mortality. The TB data was analysed using descriptive and inferential statistics to test the null hypothesis at the significance level of p< 0.05. The study was limited to only new patients enrolled between the periods from the 1st January 2012 to the 31 December 2013. The study found that TB/HIV comorbidity was a main factor contributing to mortality among new TB patients. Eighty percent (80%) of all patients who died were HIV positive. Poor CD4 monitoring, delays or failure to initiate TB/HIV comorbid patients was one of the factors associated with mortality (p < 0.0001, OR 0.51) among this cohort of patients. Poor DOT support system significantly (p< 0.0008, OR 0.81) contributed to mortality in this district. The study also found significant association between mortality and failure to initiate comorbid patient on co-trimoxazole prophylaxis (Chi-square =9.1; df=1; p=0.0025). Tuberculosis and HIV comorbidity, and delays or failure to providing antiretroviral therapy to HIV positive patients were the main factors responsible for TB mortality in Zululand Health District. The whole phenomenon was attributable to health worker related factors. Good TB/HIV clinical management guidelines and protocols developed by the Department of Health, and distributed to all health facilities did not alleviate the problem. Support and supervision could translate policies and protocols to action.

University administrations and funders would be better able to stimulate research if they had insights into context-specific, institutional constraints, and enablers. Yet, there is surprisingly little research on the determinants of research productivity amongst academics employed in the higher education sector, particularly in the global south. Barriers and enablers of research at the individual level may differ, and experience of such may vary across career stage. The objective of the research reported here was to determine what enables and motivates some academics at Rhodes University (South Africa) to do research, what problems and constraints may be making it difficult for those who may wish to do more, and how do these vary in relation to research career stage. An anonymous online survey, with follow-up focus group discussions was used to collect the data. Results show similarities to studies in developed countries, but also reveal disciplinary and career stage differences, which suggest that institutional policies need to take these factors into account when designing support or incentives.

- Description: Organisational change has proven to be a major challenge for many businesses worldwide with the pharmaceutical environment being no exception. The pharmaceutical industry is increasingly pressurised by stakeholders who seek reduced cost, higher value and quality. This has resulted in many pharmaceutical businesses attempting to launch various continuous improvement methodologies, which ultimately fail. Whereas failure of continuous improvement undertakings within the pharmaceutical environment is well documented, this study aimed to understand the factors that influence the successful sustainability of such endeavours. The purpose of this study was therefore to identify and create an understanding of the factors that influence a culture of continuous improvement within the pharmaceutical environment. The literature review revealed that factors such as leadership, teamwork, communication, continuous improvement capability and a continuous improvement mind-set contributed to the successful implementation of a culture that embraces continuous improvement. It was recognised that building a culture of continuous improvement is not instantaneous and that it requires all stakeholders to be committed and to acknowledge that changing culture requires time. An empirical study with a questionnaire as data collecting instrument was conducted to assess respondents’ perceptions of the levels of continuous improvement, leadership, teamwork, communication, continuous improvement capability and a continuous improvement mind-set within a selected pharmaceutical manufacturing business. The study revealed that all these factors were related and influenced a culture of continuous improvement. Furthermore, leadership and a continuous improvement mind-set proved to have the most significant relationship with a culture of continuous improvement. Recommendations were provided for the creation of a culture of continuous improvement in pharmaceutical businesses.

- Language: English

- Description: BACKGROUND: Diabetes mellitus (DM) is one of the problematic non-communicable diseases and is a major global public health challenge which affects more than 300 million individuals globally. It is predicted that by the year 2025, approximately 12.3 million South Africans will be receiving treatment for chronic conditions; included in that number will be those living with HIV and diabetes. An individual’s health behaviour is mainly determined by one’s demographic factors such as social, economic and cultural background. These influence people living with type 2 diabetes mellitus and have an impact on their treatment adherence. OBJECTIVES: The purpose of the study was to examine the economic, psycho-social and cultural factors influencing adherence to treatment amongst patients with type 2 diabetes mellitus in order to inform public health policy concerning the treatment and management of diabetic patients. METHODOLOGY: This was a cross-sectional, descriptive quantitative study involving 300 purposively selected clients attending health facilities in Intsika Yethu sub district of Chris Hani, Eastern Cape Province. A self-designed questionnaire was used for data collection. The questionnaire focuses on demographic information (age, gender, marital status, level of education, employment status, number of dependents, duration of taking anti-diabetic medication and existence of other chronic conditions) and the knowledge and attitude of diabetic clients regarding anti-diabetic treatment adherence. Other sections of the questionnaire solicit information on economic, psychosocial and cultural factors affecting adherence to diabetic treatment. The questionnaire was tested in a pilot study in order to identify unclear questions, so that they can be rectified before the main study was conducted. FINDINGS: Based on the findings from the study, a total of 177 (59.0percnt) of the diabetic clients had hypertension and that showed the relationship between diabetes and hypertension. On the attitude session, respondents have shown a positive attitude towards treatment. Furthermore, other objectives such as those focusing on economic, cultural and psychosocial factors were found not to be associated with poor adherence to anti-diabetic treatment. According to respondents’ responses, economic factors showed no influence on treatment adherence. Socio-cultural factors indicated that respondents never missed social gatherings and never used traditional medication to treat their diabetes. On the knowledge section which had fourteen questions, most clients seemed to be aware of the complications of diabetes and the benefits of adhering to anti-diabetic treatment because the lowest score was 50percnt. DATA ANALYSIS: The data was captured in Microsoft Excel (MSEXCEL) for onward processing. Data was analysed using data analysis and statistical software version 14. (STATA). Frequencies and percentages were used for describing the categorical variables while mean and standard deviation were used for describing age, number of dependents, duration of illness and knowledge. An independent t-test was used to determine the differences between males and females across the variables. A p-value of 0.05 was of statistical significance. CONCLUSION: Economic, psychosocial and socio-cultural factors were not found to have impacted on adherence to treatment. These findings should not be generalised as the study was done on a small sample; further research and more studies need to be conducted.

- Description: In the late 1990s, customer relationship management (CRM) was formed as a popular business term, which holds the same roots as relationship marketing and enhances the paradigm with the emerging information technologies (Öztayşi, Sezgin, Özok, 2011:944). For a supply chain to be effective, an organisation must decide on the nature of the relationship appropriate to product and market conditions and adapt management practises to that relationship (Bensaou, 1999:35). Current competitive challenges induced by globalisation, and advances in information technology have forced companies to focus on managing customer relationships. This study offers a modest contribution to evaluating factors influencing customer relationship management at an automotive component manufacturer in East London. The challenge for businesses is changing the current paradigm to a customer-centric approach. A theoretical overview was conducted to evaluate various definitions, CRM models, factors influencing CRM and the impact of competitive advantage on critical success factors. The research highlighted a number of common themes of CRM, which includes keeping the customer happy, customer satisfaction, reciprocal relationship between the organisation and employees, enthusiasm, involvement and motivation. This research identified which factors make positive contributions to key competitive advantage outcomes such as price, quality, delivery and flexibility capability. The study included an evaluation of findings. From the survey responses, the results were used to draw conclusions and develop various recommendations. The conclusions centered on the customer relationship management success factors defined in the survey. The results were then compared to previous studies. Survey findings of the current study and those of past studies were discussed. The recommendations focused on the top items identified in each factor group. Many factors influence CRM success in the organisation. The findings led to the conclusion that top management needs to support, and place focus on key activities that form part of the value proposition, capabilities and mix of resources on the CRM process, as well as the people and the procedures that make effective value creation.

- Description: The purpose of the study was to determine the factors influencing participation in Employee Health and Wellness programmes rendered by South African Police Service. Qualitative method was used and case study design was chosen. Data was collected from twenty-two participants. Semi structured interviews was used as an instrument to collect data. Interpretivism paradigm was followed for data analysis. The findings of this study revealed that participation in EHW Programmes is indeed low at Mdantsane Accountable Police Station. Most of the participants did not show any interest in the services rendered by SAPS. Their belief systems and perceptions about EHW Programs are a contributing factor to the non-utilisation of the services. One major factor that was identified by this research was the impact police training has on the decisions police members make to participate or not to participate in EHW Programmes. SAPS is a male dominated organisation, with employees that are rooted in cultural beliefs. Some participants, especially men mentioned that it is against their culture to talk about their personal problems to strangers, referring to EHW Professionals, others believed that seeking professional help from a female professional is a sign of losing your manhood an indication that you are weak. With this kind of personal belief, the researcher is of the view that SAPS has to consider adopting a new EHW Model, a model that will be relevant to the objectives of SAPS. Engaging police officers in physical activities will be more effective in promoting participation because Police work requires that police members need more than just task competencies or technical knowledge to do their work (Turner, 2014), they need to be physically fit in order to protect themselves and the community they are serving. Engaging them in counselling and educational programmes will not increase participation since they regard such services to be meant for the weak police officers.

- Description: Reading has become the national and international centre of debate as learners persistently read below the required levels and matriculation results are due to learners’ poor reading competencies. The concerns about poor reading competencies has mounted into inflammatory statements in articles and popular media nationally, continentally and internationally. Without the ability to read learners are deprived access to pertinent information and knowledge that can assist individuals in lifelong learning. Being a language teacher, the researcher in this study strongly believe that every learner can read appropriately and teachers can assist learners to improve their reading competencies. The purpose of the study wasto identify the factors contributing to poor reading competencies of grade 4 learners and to provide recommendations to assist in dealing with poor reading competencies. Qualitative research approach was undertaken to deal with all aspects related to research methodology.The data were collected using research instruments such as observation of six learners from three selected primaryschools. The observation was conducted during readingof textby learners in the presence of English teachers. The questionnaires were distributed to eleven teachers offering English in grade 4 as another means of data collection instrument.Major findings of the study revealed that factors affecting reading competencies are hugely emanated from schools, teachers, family background, departmental policy and learners themselves. Despite reading problems exist in schools, there are always positive solutions to bring hope and success to the learners
