- Description: The challenge of child mortality between the ages of 0 and 5 years has extensively increased over the past few years. Furthermore, the ever-evolving and complex consequences of ineffective monitoring of children’s growth and development have been identified as one of the reasons for this increase in child mortality. The Road-to-Health Chart was developed and redesigned for use by child nurses and midwives to monitor children’s growth and development. The purpose of this study was to investigate whether the midwives at community healthcare centres in the Nelson Mandela Bay area had the necessary knowledge to utilise the Road-to-Health Chart effectively. Permission to conduct the study was sought from the Nelson Mandela Metropolitan University, the Department of Health and the participants. A quantitative, non-experimental descriptive survey was used in this research. The population consisted of all the midwives working in the Midwife Obstetric Unit and community healthcare centres within the Nelson Mandela Bay Municipal area. The sample was extracted from the targeted population but from willing participants that met the inclusion criteria. The research data-collection method was a self-developed questionnaire with closed-ended statements to measure the knowledge of how effectively the midwives in the Nelson Mandela Bay area were using the RTHC. The researcher ensured the validity of the questionnaire by focusing on the instrument’s validity, construct validity, content validity and face validity. Ethical considerations, including permission, informed consent, confidentiality and anonymity, were adhered to. The most significant findings showed that midwives at CHCs and MOUs in the Nelson Mandel Bay area were knowledgeable about the importance of the RTHC to the mother and child and the use of the RTHC. These findings may assist in the identification of measures to enhance the knowledge of midwives about the use of the RTHC thus ultimately facilitating the use of the RTHC by mothers as intended.

- Description: Over the last century, the population of the world has more than doubled, resulting in an increase in seafood consumption (FAO 2010), and placing strain on fisheries wild stocks, their habitats, and the coastal communities that rely on them for food and survival. The ecosystem approach to fisheries (EAF) differs from other management approaches by combining all aspects of ecosystem management, and strives to conserve ecosystem structure, maintain diversity, productivity, and integrity, and to meet human food and economic needs. This study aims to assess how South Africa is progressing in implementing EAF in principle and in practice, to identify challenges, and suggest solutions, where appropriate. The law sets precedence on governance. An assessment of the Marine Living Resources Act, (MLRA) and the South African Policy for Small-scale Fisheries (SSFP) revealed that, although these instruments recognise and contain elements of EAF, this management approach has not been adequately implemented. In practice, the status of implementation of EAF was assessed through the Southern African Sustainable Seafood Initiative (SASSI) and the Ecological Risk Assessments (ERA). The scores of 65 assessments, conducted in 2013 and 2014, were obtained from SASSI. Of the 65 species assessed; 18.4% were listed as Green, 50.8% were listed as Orange and 30.8% were listed as Red. Two methods were used to analyse the data; non-metric multidimensional scaling (NMDS), and cluster analysis in the statistical program R. Analysis of the SASSI assessments indicates that there has been progress in implementing EAF since the World Summit on Sustainable Development in 2002. The high number of Orange and Red listed species however, indicate that major sustainability issues still exist. Species in commercially important fisheries enjoy the bulk of research and management attention compared to other species, including bycatch species, as reflected by a high proportion of Green-rated commercially important species. Based on these results, four fisheries were chosen for further indepth analysis using additional information found in ecological risk assessments: offshore demersal trawl, inshore demersal trawl, West Coast rock lobster fishery and the line fishery. The documents and published literature of the Department of Agriculture, Forestry and Fisheries Internal Scientific Working Groups provided further information. A Wilcoxon signed rank test conducted in the programme R on the results of the ERAs showed that there was a decline in implementation of EAF and reinforced the earlier conclusion that large commercial fisheries, offshore and inshore demersal trawl, were progressing in implementing EAF faster than West Coast rock lobster and line fisheries, which are examples of smaller-scale fisheries that are more accessible to many resource users. Both progress and challenges appeared to be largely influenced by several common factors, which include the presence or absence of positive incentives, co-management, management plans, access, compliance, economic importance, capacity, and the interests of rights holders and other stakeholders.

- Description: This study seeks to evaluate economic development in the Eastern Cape Province, with a special focus on the agricultural sector. It focuses on the role that Development Finance Institutions (DFIs) play in stimulating economic development. To achieve this, the Eastern Cape Development Corporation (ECDC) was considered as a case study in assessing DFI’s support to the agricultural sector in the province. The study will also look into the corporation’s adherence to the Provincial Growth and Development Plan (PGDP) and its strategic programmes. The study examines how the agricultural initiatives financed by ECDC contribute to economic development in the province. It will also assess whether those agricultural projects may impact the local communities through poverty alleviation. In order to address the research problem and to achieve the research objectives, available literature and empirical work related to the relationship between financial system development and economic development was reviewed. The research revealed that the role played by the ECDC with regard to Agricultural Projects has not been entirely effective to add value to economic development in the province, mainly caused by the lack of non – financial support by skilled people from the corporation, after limited funding was made available. From the investigation, the findings indicate that the effective mplementation of these projects require strengthened capacity, which requires more skilled officials from the corporation to assist the agricultural enterprises in managing the projects; and more funding that will assist the projects to reach sustainability.

- Description: The main focus of this study was to perform an assessment of viable and sustainable means of creating a vibrant and sustainable economy in the Mdantsane Township. In order to perform the assessment objectives were formulated which aimed at assessing whether the informal small business sector of Mdantsane was generating wealth and livelihoods for the people running them. The study also looked at whether the informal business sector is a preferred option by most South Africans or people in the townships would rather seek employment. A number of data collection methods were used in completing this study such as literature reviews and a semi-structured questionnaire. The study revealed that Local Economic development can be implemented in the townships in order to assist in stimulating a vibrant local township economy. The study also revealed that the central focus of Local Economic Development is to support the development, growth and retention of private or co-operative enterprises. The survey conducted in the study further revealed that most businesses in the township are driven by necessity in order for them to start their businesses mainly due to unemployment. These businesses all agreed on the significant role that Local Economic Development can play in assisting township entrepreneurs and communities to grow and prosper.

- Description: Constitution of the Republic of South Africa, in Chapter 7, requires all municipalities to encourage members of the public to participate in the matters of local government. Public participation is the process by which public concerns, needs, and values are integrated into governmental and corporate decision making. The Integrated Development Plan is an example of local government instruments which seek public participation in order to address community needs through service delivery. Consequently, this study was to explore the role of public participation in the Integrated Development Planning process of the Chris Hani District Municipality. The main objectives of this study were to understand the IDP making process, establish the importance of public participation, understand the role played by the municipality to encourage public participation in the IDP processes, understand the influence of IDP in service delivery and to make recommendations based on the findings presented. To conduct this study, qualitative research methodology was employed. The population sample comprised of councillors and municipal officials. Structured interviews were conducted with the councillors, while semi-structured interviews were held with municipal officials. The findings of the study revealed that the Chris Hani District Municipality views public participation as an integral part of the IDP making process. Measures and strategies are taken by the municipality to enhance public involvement in all matters of the municipality, including the IDP process. To achieve this the municipality partners with a number of stakeholders such as the local municipalities, government departments and organised groups. However, this is not enough hence recommendations are presented to improve this situation. Recommendations proposed include introducing capacity building programmes for councillors, establishment of a public participation unit, availing budget for public participation and educating members of the public about public participation and the IDP process.

- Description: Biochar is being promoted as an amendment to improve soil properties, crop productivity, and carbon sequestration. In Africa, biochar adoption is hindered by production systems which include technology and feedstocks availability. However, little research has been published on the influence of biochar incorporation on soil chemical properties and early crop establishment. The aim of this study was to characterize biochar from cattle, goat, sheep and poultry kraal manures and their effect on soil properties and crop growth. This was guided by the following specific objectives, (i) to explore the mixed-farming system of Raymond Mhlaba Municipality on availability and utilization of livestock kraal manures (ii) to characterize biochar samples produced from cattle, goat, sheep and poultry kraal manures (iii) to determine the nutrient release patterns of biochars amended in a degraded soil (iv) to determine the effectiveness of converting manure to biochar and cattle manure on maize early development and, (v) to determine the effects of biochar type and application rate on early maize development. The farming system was surveyed to identify quantities of livestock manure, its availability and utilization for soil fertility amendment in cropping in the Raymond Mhlaba Municipality. The emerging results across all the villages revealed that, the mean livestock numbers were, 9.24±8.21 sheep, 9.37±8.15 goats, 7.95±7.66 cattle and 9.02±9.47 chickens. The findings revealed that 94 (82.4percent) of the respondents had access to cropland allocations in the form of outfields and homegardens. However, only 55 (48.2percent) of the respondents were currently cropping their fields. Maize was the most common crop grown followed by butternuts and potatoes. The application of manure by the respondents currently cropping their lands was only 40 (35.1percent) and the quantities used ranged from 210-1450 kg ha-1. The results further showed that the estimated total manure production was 2.9 t year-1, 0.82 t year-1, 0.04 t year-1, and 0.8 t year-1 from cattle, goats, chicken, and sheeps respectively. Drum retort method of slow pyrolysis at a temperature of 400°C was used to produce biochar from cattle, goat, sheep and poultry manure feedstocks. The biochar yields were 63percent, 72percent, 61percent and 83percent on a weight basis for the different feedstocks. The chemical properties of the biochar were significantly different from those of the manure from which they were made. Biochars that were high in Ca and K such as poultry manure biochar and sheep manure biochar indicated higher pH and electrical conductivity values. For instance, sheep manure biochar was (8.1 mS cm-1) and poultry manure biochar was (9.2 mS cm-1). The scanning electron microscopy (SEM) revealed that, the biochars had porous structures ranging from 1.23um to 5.23um in diameter which are important for water conductance and holding capacity. The target soil carbon level to determine the effects of biochar soil incorporation was 2percent and the soil had 0.7percent. Therefore, it was treated with four livestock manure biochars at application rates of 0; 53.2 t ha-1 (CMB); 48.1 t ha-1 (GMB); 50.7 t ha-1 (SMB); and 40.2 t ha-1 (PMB) based on their carbon content to supplement the soil carbon difference. The effect on soil pH was such that SMB increased to 6.44, PMB (6.45), CMB (6.54), and GMB (6.53) relative to the control which did not show any changes. An increase was also observed on Olsen P concentrations (mg P kg-1) which varied with biochar treatments: PMB (6.22), GMB (6.37), SMB (6.44) and CMB (6.44) and were significantly higher than the control. Ammonium-N(NH4+) concentrations (mg NH4+-N) were increased in biochar treatments but, no significant differences were obtained with sampling time. SMB released 7.95 mg kg-1, CMB 7.50 mg kg- 1, PMB 7.46 mg kg-1 and GMB 7.05 mg kg-1, compared to the control 3.23 mg kg-1. Maize growth in soil sampled from farmers fields in cultivation and abandoned treated with biochar without application of inorganic fertilizer did not differ with control (soil only) treatments. However, maize growth in soil treated with biochar and inorganic fertilizer was comparative to manure treatments. This resulted in a follow up study to elucidate the effects of biochar alone and was carried out with cattle, goat, sheep and poultry biochars at five application rates (0, 100, 200, 300, and 400 kg C ha-1) applied to a sandy loam and a clayey loam soil of the Oakleaf and Tukulu soil forms respectively. Post-harvest soil pH, electrical conductivity and Olsen P showed improvements in biochar treatments relative to the control. Improvements in the chemical parameters and plant growth increased simultaneously with biochar application rate. Maize growth was not affected by biochar application at different rates.

- Description: The study evaluated the use of saliva as a minimally invasive technique for cortisol level determination. This was done by assessing the relationship between serum and saliva cortisol based on short sampling intervals. In addition, the study also determined the effect of successive handling on faecal glucocorticoid metabolites (FGM), rectal temperature (RT), avoidance distance (AD), chute and crush scores as well as urination, defaecation and vocalization in multiparous cows. For trial one six non-pregnant, clinically healthy Nguni cows were used. They were administered with standardised doses of adrenocorticotropic hormone on treatment days and saline was used as a placebo on alternative days. Simultaneously, blood and saliva samples were collected to quantify cortisol levels. No relationship (r = 0.0131, P>0.05) was observed between serum and saliva cortisol. However, results showed that there was adrenal stimulation in saliva coupled by significant (P<0.05) effects of sampling intervals. For the second study 21 non-pregnant and clinically healthy Nguni cows of one herd were used for the trial. They were divided into parity groups and their weights were used as a covariate in data analysis. For five consecutive weeks, fresh faecal samples were extracted and rectal temperatures measured. In addition, fear of approaching humans was assessed by AD scores and behaviour scores in the crush chute, as well as vocalisation, urination and defaecation were observed. The effect of successive handling significantly (P<0.05) affected the physiological parameters, namely FGM and RT. Contrariwise, Chi-square tests revealed that parities had a significant (χ2 < 0.05) influence on AD and crush scores as well as on the occurrence of excretory behaviour. It was concluded that saliva cortisol can be used as a stress indicator in beef cows. However, plasma cortisol can be significantly volatile thereby becoming less sensitive to changes across time. This can cause a lack of relationship between plasma and saliva cortisol. On the other hand, repetitive handling of beef cows has an influence on faecal stress levels. In addition, beef cows of differing parities behave differently to handling stress.

- Description: The study evaluated the use of saliva as a minimally invasive technique for cortisol level determination. This was done by assessing the relationship between serum and saliva cortisol based on short sampling intervals. In addition, the study also determined the effect of successive handling on faecal glucocorticoid metabolites (FGM), rectal temperature (RT), avoidance distance (AD), chute and crush scores as well as urination, defaecation and vocalization in multiparous cows. For trial one six non-pregnant, clinically healthy Nguni cows were used. They were administered with standardised doses of adrenocorticotropic hormone on treatment days and saline was used as a placebo on alternative days. Simultaneously, blood and saliva samples were collected to quantify cortisol levels. No relationship (r = 0.0131, P>0.05) was observed between serum and saliva cortisol. However, results showed that there was adrenal stimulation in saliva coupled by significant (P<0.05) effects of sampling intervals.

- Description: Pressures from environmental agencies contribute to the challenges associated with the disposal of waste tyres, particularly in South Africa. Recycling of waste tyres in South Africa is in its infancy resulting in the historically undocumented and uncontrolled existence of waste tyre stockpiles across the country. The remote and distant locations of such stockpiles typically complicate the logistics associated with the collection, transport and storage of waste tyres prior to entering the recycling process. In order to optimize the logistics associated with the collection of waste tyres from stockpiles, useful information about such stockpiles would include estimates of the types of tyres as well as the quantity of specific tyre types found in particular stockpiles. This research proposes the use of computer vision for categorizing individual tyres and estimating the number of visible tyres in tyre stockpile images to support the logistics in tyre recycling efforts. The study begins with a broad review of image processing and computer vision algorithms for categorization and counting objects in images. The bag of visual words (BoVW) model for categorization is tested on two small data sets of tread tyre images using a random sub-sampling holdout method. The categorization results are evaluated using performance metrics for multiclass classifiers, namely the average accuracy, precision, and recall. The results indicated that corner-based local feature detectors combined with speeded up robust features (SURF) descriptors in a BoVW model provide moderately accurate categorization of tyres based on tread images. Two feature extraction methods for extracting features for use in training neural networks (NNs) for tyre count estimations in tyre stockpiles are proposed. The two feature extraction methods are used to describe images in terms of feature vectors that can be used as input for NNs. The first feature extraction method uses the BoVW model with histograms of oriented gradients (HOG) features collected from overlapping sub-images to create a visual vocabulary and describe the images in terms of their visual word occurrence histogram. The second feature extraction method uses the image gradient magnitude, gradient orientation, and edge orientations of edges detected using the Canny edge detector. A concatenated histogram is constructed from individual histograms of gradient orientations and gradient magnitude. The histograms are then used to train NNs using backpropogation to approximate functions from the feature vectors describing the images to scalar count estimations. The accuracy of visible object count predictions are evaluated using NN evaluation techniques to determine the accuracy of predictions and the generalization ability of the fit model. The count estimation experiments using the two feature extraction methods for input to NNs showed that fairly accurate count estimations can be obtained and that the fit model could generalize fairly well to unseen images.

- Description: Faecal indicator bacteria have long been recommended for usage in water quality monitoring of various water sources including surface water. A large number of people in different parts of the world often engage in recreational and other commercial activities at the various beaches along the coastal lines, most especially, during summer season and festive periods. It is generally assumed that beach water is safe all the times, however, there have been increasing reports of beach and other coastal water pollutions because of rising anthropogenic activities around coastal areas globally. The presence of pathogens in faecal contaminated beach water either directly or indirectly increases the risk of human exposure which may result in skin infections as well as the ingestion and transmission of multidrug resistant pathogens. Microorganisms may gain entry into beach water directly from improperly treated final effluents released by wastewater treatment plants and from agricultural runoffs and/or faulty drainages. The aim of this study was to evaluate the quality indices of the Nahoon Beach and canal waters in the Eastern Cape Province of South Africa. In order to achieve this aim, the objectives of this study were as follow: to determine the seasonal variations of the physicochemical characteristics of the Nahoon beach and canal waters, to assess the microbiological quality of the beach water by assessing the prevalence of potentially E. coli and Enterococcus species, and to evaluate the antibiogram profile of the E. coli pathotypes and Enterococci species recovered from the beach water samples. Water samples were collected bi-weekly for a period of twelve months, during which on-site physicochemical analyses were carried out. Bacteriological assessment was performed using the membrane filtration technique and the necessary incubation conditions were followed. Identification of the target organisms was done by molecular based methods using PCR (polymerase chain reaction) while antibiotic susceptibility testing was done using the disk diffusion method. During the spring season (August to October) and periods of festive activities (December, January and March), it was observed that turbidity was at its highest, consequently, influencing total dissolved solids and a rise in the values of pH and electrical conductivity. Microbiological qualities assessed follow the order: Escherichia coli (101 – 103 CFU/100ml) and Enterococcus (101 – 102 CFU/100 ml). The results show that 41.2percent (107/260) of the presumptive E. coli isolates were positive for uidA gene. A total of 73 out of 107 (68.2percent) PCR-confirmed E. coli isolates were observed to belong to different pathotypes while 59percent (102/172) of the presumptive Enterococcus strains isolated were positive for SodA gene (Enterococcus spp.). Out of 102 enterococci isolates, 45 strains were identified as species (E. faecalis and E. faecium) and these were subjected to antibiotic susceptibility testing. The E. coli strains exhibited a frequency of 100percent resistance against ampicillin while the Enterococcus strains also showed 100percent resistance against vancomycin and linezolid. Target genes eae 11 (10.3percent); ipaH 14 (13.1percent); ibeA 48 (44.9percent) that encode pathogenicity in E. coli were successfully amplified by PCR suggesting that the isolates are potentially pathogenic strains whereas Enterococcus spp. including Enterococcus faecalis 26 (25.5percent) and Enterococcus faecium 19 (18.6percent) were also identified in the water samples. In this study, the phenotypic antibiogram profiles of the E. coli isolates revealed that all 73 (100percent) of the pathotypes were resistant to ampicillin, 67 (91.8percent) were resistant to amikacin, gentamicin and ceftazidime while about 61 (83.6percent) and 51 (69.9percent) were resistant to tetracycline and ciprofloxacin as well as trimethoprim respectively. About 21.9percent (16) of the E. coli isolates exhibited multiple antibiotic resistances with 100percent being resistant to eight antibiotics whereas multiple antimicrobial resistances were observed in 14 (31percent) of the enterococci strains and the most predominant profile was the simultaneous resistance to ampicillin, penicillin and vancomycin. The results obtained in this study show that the beach water generally did not comply with the set guidelines. The results also suggest the possible survival and prevalence of potentially virulent E. coli as well as Enterococcus strains in the aquatic environment which may be a cause of concern for public health. Monitoring of the quality of surface water and antimicrobial resistance (AMR) in bacteria is of great importance and has clinical and human health significance. Nonetheless, this study underscores the need for more detailed study of other waterborne pathogens of health importance including enteric viruses to ascertain the safety of the beach for human use.

- Description: Since the global financial crisis of 2008, attracting investment in a public company has not been a simple task (Krzus, 2011). Public trust in organisations was lost as a result of the crisis, owing to the lingering economic uncertainties that prevailed (Krzus, 2011). Through the full disclosure of all aspects that affect the operations of an entity, investors will be assisted in making an informed decision prior to making an investment in a publicly traded company (Singh, Wei, & Kaur, 2012). Integrated reporting provides investors with the necessary details, by making full disclosure of all aspects that affect the operations of an entity, including both financial and non-financial information, in a single report. Such information will enable investors to make a more informed assessment of the future prospects of the organisation in which they intend to invest (Singh et al., 2012). The purpose of this research effort, therefore, was to determine the relevance of integrated reporting to professional investors when making investment decisions, focusing specifically on JSE-listed construction companies. Grounded theory was used as a research design method. Grounded theory summarises data collected from empirical sources into categories. The data collected were based on the subjective perceptions of the participants in response to investigative interview questions. The researcher focused on a single context, namely an investment made by professional investors in JSE-listed construction companies within the Durban metropolitan in KZN. Non-probability, purposive sampling was used as the findings were not generalised to the entire population but were limited to the opinions and perceptions of professional investors in the Durban metropolitan area. The research effort resulted in valuable insight into how integrated reporting can be a useful decision-making tool for professional investors when undertaking investment in listed construction companies, in an attempt to attract investment in the sector. The researcher experienced a lack of responses from professional investors within the industry who were contacted for interviews. This lack of response could be considered to be a limitation in validating the outcome of the study. “Investors and integrated reporting” was identified as a theme that is material to the current state and potential future development of integrated reporting. Accordingly, this theme was used as a basis for this research effort that will enhance companies’ awareness of the benefits of compiling integrated reports as a tool to attract investors. This will assist in obtaining finance that can be used to develop and grow organisations.

- Description: Cormac McCarthy’s Blood Meridian or the Evening Redness in the West is a provocative evocation of the American West that has attracted a wide range of critical responses. This study has three foci: the novel as epic myth, McCarthy’s critique of Manifest destiny, and the influence of Nietzschean philosophy on the judge and McCarthy’s portrayal of the human condition. These concerns conduce to an alternative reading of the conclusion of the novel. Blood Meridian is a unique textual enterprise as it both conforms to and subverts mythic conventions associated with both Classical epic and the American West. Recognition of the resonances between Blood Meridian and these mythologies helps the reader to engage with McCarthy’s ambitious creation of a powerful literary allegory in the tradition of Twain and Faulkner. Having situated McCarthy’s enterprise within these co-ordinates, the study then moves on to examine the novel’s stunning critique of Manifest Destiny, in the context of the implications that such thinking has had on American foreign policy over the past two centuries, and that continue to inspire American involvement in military conflicts well into the twenty-first century. The final area of focus is the influence of Friedrich Nietzsche’s philosophy on the character of the judge and the weltanschauung that the novel presents. McCarthy’s ultimate objective is to demonstrate that humankind’s most basic condition is an inherently violent one. The more critically accepted reading of the novel is challenged by postulating the kid’s triumph over the judge as not only in keeping with the literary tradition of Melville and others but also a logical outcome of the novel’s allegory of American military involvement in Vietnam. The study concludes that whilst McCarthy has gone on to receive critical acclaim and public praise for works published after Blood Meridian, this work remains both his artistic masterpiece and his most far-reaching engagement with issues of eschatological and political importance. It is argued that, given the contemporary escalation in geo-political tensions, Blood Meridian may well continue to provide insight into the nature of American domestic and foreign policy for decades to come.

- Description: The purpose of this case study research effort was to develop and propose a theoretical model for the successful implementation of franchising in the South African chicken-based fast food industry. Design/Methodology/Approach - A single case with embedded units of a franchisor and a franchisee was initially adopted, but inaccessibility to respondents resulted in the adaptation of the study into a single holistic case. This is justified as the case serves a revelatory and explanatory purpose (Yin, 1994, p. 44). The case provided insight into the implementation processes of franchising in the South African chicken-based fast food industry; where franchised chicken-based concepts are leading the industry. The inaccessibility to original target respondents considered a limitation in the original research design. The limited contextual knowledge of the transcriber, and inexperience resulted in a sub-par transcript which slightly limited the interpretation of the data. Originality/Value – The case study examines the current implementation of franchising in the South African chicken-based fast food industry; with particular focus on the chicken-based fast food franchise systems which have consistently outperformed other types of fast food franchise systems. The proposed theoretical model can be applied in any industry or geographical location with an adjustment of the model‟s contextual considerations.

- Description: There is limited research pertaining to assessing the happiness levels of various disciplines within the healthcare industry. Furthermore, happiness and physiotherapy studies are two research areas that are not necessarily associated with one another on a global perspective. Hence, the happiness levels have not been adequately established for private physiotherapists. This treatise is the first attempt to evaluate the happiness levels of private physiotherapists in South Africa. A thorough literature review was conducted to determine the current climate of happiness studies pertaining to the business industry, with focus on private physiotherapy businesses in the healthcare sector. The literature review enabled the development of a hypothesised model, which was tested with quantitative techniques consisting of a questionnaire, data collection and statistical analysis. The research confirmed that influence, social relations, life balance, optimism, work and leisure are all positively associated with the happiness levels of private physiotherapists in South Africa. These variables are recommended as key focus areas for physiotherapy business owners to address, in order to positively affect happiness levels in the workplace and thereby create favourable bottom line results. In accordance with the reviewed literature and the findings of this treatise, by adequately addressing these variables the business owners of physiotherapy practices will generate a workforce that are more productive, demonstrate greater collaboration with colleagues and customers, produce happier customers, are more positively energised and are less absent and more loyal to the business. It is recommended that the proposed model is tested to provide further benefit to the industry by constructing evidence-based retention and recruitment strategies for high performing private physiotherapy staff.

- Description: There is limited research pertaining to assessing the happiness levels of various disciplines within the healthcare industry. Furthermore, happiness and physiotherapy studies are two research areas that are not necessarily associated with one another on a global perspective. Hence, the happiness levels have not been adequately established for private physiotherapists. This treatise is the first attempt to evaluate the happiness levels of private physiotherapists in South Africa. A thorough literature review was conducted to determine the current climate of happiness studies pertaining to the business industry, with focus on private physiotherapy businesses in the healthcare sector.

- Description: South Africa’s health status is in constant dismay, especially while under the strain of the quadruple burden of disease. The adoption of personal electronic health records (PEHRs) can be seen as a means to improve this status by empowering patients to manage their health and lifestyle better. While from the healthcare provider’s perspective, PEHRs has the ability to reduce medical errors; provide better communication channels and enhance the monitoring of patients. Despite these benefits for both healthcare providers and patients, there are three distinct information security threats relating to PEHRs. These threats refer to the individual, data in transit, and at rest. South Africa is still considered to be inexperienced with PEHRs, and consider it a relatively new concept to the healthcare system. The National e-Health Strategy and Protection of Personal Information Bill were discussed and compared to international standards in order to ascertain South Africa’s current standing on mobile healthcare privacy. However, there are no specific privacy and security controls in place to protect patients that access personal electronic health records through mobile devices. Therefore, the aim of this study is the development of a privacy management framework (PMF) to mitigate these privacy concerns. Following an interpretivistic approach to research, qualitative data was analysed from literature, and the privacy framework evaluated through expert reviews. The proposed PMF consists of 3 tiers, beginning with the top tier. The first tier relates to an organisations interpretation and understanding of data privacy laws and regulations, and in ensuring compliance with these laws. The second tier refers to two support pillars to maintain the first tier. These pillars are based on elements of operational privacy, as well as auditing and reviewing. The third tier serves as the basic foundation upon which the PMF was developed. It is mainly focused with creating privacy awareness amongst healthcare providers and patients by creating: training regimes on security and privacy threats, efficient communication standards, and constant ongoing support from top level management.

- Description: A brief history of political correctness is discussed along with various definitions of it, ranging from political correctness being a benign attempt to prevent offense and avert discrimination to stronger views equating it with Communist censorship or branding it as "cultural Marxism". The aim of the research is to discover what political correctness is, how it relates to freedom of expression and what wider implications and effects it has on society. The moral foundations of rights and free speech in particular are introduced in order to set a framework to determine what authority people and governments have to censor others' expression. Different philosophical views on the limits of free speech are discussed, and arguments for and against hate speech are analysed and related to political correctness. The thesis looks at political correctness on university campuses, which involves speech codes, antidiscrimination legislation and changing the Western canon to a more multicultural syllabus. The recent South African university protests involving issues such as white privilege, university fees and rape are discussed and related to political correctness. The thesis examines the role of political correctness in the censorship of humour, it discusses the historical role of satire in challenging dogmatism and it looks at the psychology behind intolerance. Political correctness appeals to tolerance, which is sometimes elevated at the expense of truth. Truth and tolerance are therefore weighed up, along with their altered definitions in today's relativistic society. The last part of the thesis looks at South Africa's unique brand of political correctness, along with Black Economic Empowerment, colonialism and white guilt, and the research concludes that political correctness is a distinct form of censorship which has developed in modern democracies. The new forms of justice and morality seen in political correctness are distortions of left-wing liberalism, which appeal to different values to those of traditional liberalism.

- Description: The incorporation of best practice in e-learning environments can increase the probability of success for companies and learners alike. By identifying and understanding the barriers that potential learners may face when interacting with e-learning products, the potential for e-learning failure may be alleviated. There are a variety of benefits that may be realised by companies incorporating e-learning opportunities into their management strategies. However, certain pedagogical principles, metrics and components need to be investigated and implemented in order for a corporate e-learning environment to be successful. The aim of this research is to prototype and evaluate a practical e-learning environment for software training (eLESTP) with e-learning components consisting of interactive learning objects that can guide the development and management of online training in the corporate context. The eLESTP is based on a theoretical contribution that is conceptualised in the form of an e-learning environment for software training (eLESTT). Hence, this study followed a research methodology that is appropriate for educational technologies, namely the Design-Based Research (DBR) methodology, which was applied in iterative cycles. Quantitative and qualitative data was collected by means of a case study, interviews, a focus group and survey. The proposed eLESTP underwent several iterations of feedback and improvement and the result is a real-world solution to the problem at hand. With the purpose of determining the success of corporate e-learning, the barriers and critical success factors for e-learning as well as evaluation criteria were explored. Interviews, a focus group and a survey were conducted in order to validate the investigated literature in a real-world context. Informal interviews enabled a better understanding of the organisational context of this study. The focus group was conducted with customers who were undergoing face-to-face training using conveyancing software developed by Korbitec. Many of the issues faced by learners identified in literature regarding e-learning in developing countries were identified by the participants from the case study. An e-learning survey was used to gather information regarding the intention of Korbitec’s customers to use e-learning as well as their satisfaction with using e-learning. From the survey, it was found that respondents were positive regarding intention to use and satisfaction toward e-learning usage. DBR Cycle 1: Problem Investigation and Proposal entailed the initial problem investigation by conducting a literature review, focus group and survey. DBR Cycle 2: Design Alternative 1 of this study involved a design alternative for eLESTP, namely Prototype 1. DBR Cycle 3: Design and Evaluate Alternative 2 involved the design and prototyping of Prototype 2 for eLESTP as well as the improvement of Prototype 2 through sub-cycles of testing and refinement. The suggestions for improvement were obtained from the relevant stakeholders at Korbitec who are content developers and subject-matter experts. The criteria used to evaluate the success of eLESTP, including its e-learning components, were synthesised and adapted from literature and a new set of evaluation criteria for e-learning environments in software training contexts was proposed. The evaluated eLESTP consists of the technology basis of the Modular Object Oriented Dynamic Learning Environment (Moodle), design guidelines for e-learning components, certification and competency-based training, pedagogical principles and best practice. Overall, eLESTP was positively received by various evaluator groups in formative and summative evaluations. The research results indicate that the use of an e-learning environment for software training purposes was useful and necessary. In support of this Masters dissertation, the following three conference papers have been published and presented at one local conference and two international conferences. In addition, an article has been published in an accredited journal: 1. IDIA 2015, Conference Paper – Zanzibar (Tanzania); 2. Conf-IRM 2016, Conference Paper – Cape Town (South Africa); 3.

- Description: The success of Nigeria’s 2015 general elections was unexpected, given the tense political and security climate in which the polls were conducted. It is against this backdrop that this study explores the contribution of four newspapers (The Guardian, Vanguard, Independent and Leadership) and, in particular, their editorials, to the relatively peaceful and mostly credible 2015 general elections in Nigeria. This qualitative study, located with an interpretivist tradition, draws on both in-depth individual interviews with editorial writers, and thematic content analysis of selected editorials to explore three themes: - violence-free polls, rational voting and credible electoral process. These newspaper editorials made moral and ethical appeals urging “supra-national” and patriotic attitudes as well as more detailed process interventions. Drawing from the theories of argumentation, the research suggests that three kinds (forensic, epideictic and deliberative) of arguments were made and three modes of argumentation (logos, pathos and ethos) were used by editorial writers to advance their arguments. This study examines what the editorial writers hoped to achieve and the normative ideals they drew on in the discharge of what they saw as their editorial duties. Drawing on theoretical insights from normative theories of journalism, and particularly social responsibility theory, this research posits that editorial writers hoped to arrest the spate of violence in the Nigerian polity, raise the level of discussion and redirect the attention of politicians in particular to core issues confronting ordinary Nigerians. The study finds a correlation between the editorials written and the normative ideals embodied in the social responsibility theory, which, the study finds, is the most influential normative ideal in the ‘mainstream’ Nigerian news media, at least in print. This study thus argues that in view of the range and frequency of focus on three core themes, and the persuasive power of writing, a case can be made for the editorials of these four major newspapers playing a constructive and positive role and making some contribution to the eventual peaceful and credible outcome of 2015 national elections in Nigeria.

- Description: The Buffalo City Metropolitan Municipality (BCMM), situated in the second largest province in South Africa, the Eastern Cape, is an unfortunate victim of low economic development and high unemployment. The South African Government, through the Department of Trade and Industry, identified the need for SMMEs to address these issues with the inception of the White Paper on National Strategy for the Development and Promotion of Small Business in South Africa over 20 years ago. SMMEs in South Africa are noted to have a failure rate of around 70% which does not bode well for the efforts to improve economic development and reduce unemployment through SMMEs. This research sets out to determine the significance of variables such as human resources, financial resources, information systems, government assistance and competitive intelligence on the sustainability of SMMEs. The researcher examined the literature relating to the challenges and issues faced by SMMEs with particular emphasis on the use of competitive intelligence as a tool to assist in sustainability. The literature review was followed by an analysis and interpretation of a qualitative study of SMMEs within the BCMM. Through an analysis of the results it was possible to determine the nature of the relationships between the independent variables and sustainability. Finally, the researcher was able to make recommendations based on the research.

- Description: The world is becoming increasingly complex and uncertain due to increasing levels of social- ecological change. Rural communities in sub-Saharan Africa are faced with multiple interconnected challenges such as population growth, environmental change, economic recession and climatic changes, amongst others. Such challenges can play a key role in determining vulnerability and food security, particularly for natural resource product- dependent societies that have limited livelihood sources. Studies that consider understanding how society and ecosystems simultaneously interact and respond to new and exacerbated drivers are increasingly needed. Therefore, this study was conducted in Fairbairn village, Eastern Cape, South Africa with the purpose of exploring multi-scale historical processes and current related trends in livelihood and environmental change, and the implications for future trajectories under a changing climate. This study applied social-ecological thinking and several conceptual approaches were combined to provide a lens for exploring the changes taking place. These included, inter alia, complexity theory, social-ecological systems, the sustainable livelihoods approach and the Intergovernmental Platform on Biodiversity and Ecosystem Services framework and principles. The study employed a mixed method approach to gather data, which included a household survey, aerial photography, historical records as well as Participatory Learning and Action, focus group discussions, and Participatory Scenario techniques. Quantitative data were analysed using Excel and Statistica version 13, whilst coding was used for thematic analysis of qualitative data. The main objective of this study was to explore multi-scale historical processes and current related trends of livelihood and environmental change, and the implications of these for future trajectories under a changing climate. Livelihood and landscape changes in Fairbairn village are embedded within a history of direct state intervention and more recently, improvements in basic service delivery. The findings show that natural resource products still form an important part of people’s livelihoods despite many other changes over the last fifteen years. A high proportion of households continue to utilise different products to meet household needs. The most widely used products are fuelwood, wild herbs and wild fruits. More so, my results revealed a significant increase in the number of people commercialising natural resource products over the past fifteen years. Furthermore, I found that rural livelihoods in Fairbairn are heavily dependent on external income and consumption and have become increasingly divorced from local production patterns. My results depict a steady decline of cultivated fields with a corresponding increase of home gardens since the 1960s. Therefore, the results demonstrate that current livelihood strategies are an expression of historical processes interacting with current contextual complexities. Given the complex and multidimensional issues at play in Fairbairn, the study highlights that there is no straightforward answer regarding future livelihood strategies. However, participatory scenario deliberations revealed that the youth were much more open to diversified and even very different forms of livelihood strategies in the future, whilst community leaders and elders remained firmly attached to farming activities. Understanding the diversity of past livelihood changes, together with current trends, can help to better contextualise future livelihood trajectories and this can therefore help rural communities identify and avoid undesirable futures under a changing climate.

The main objective of this study was to explore multi-scale historical processes and current related trends of livelihood and environmental change, and the implications of these for future trajectories under a changing climate. Livelihood and landscape changes in Fairbairn village are embedded within a history of direct state intervention and more recently, improvements in basic service delivery. The findings show that natural resource products still form an important part of people’s livelihoods despite many other changes over the last fifteen years. A high proportion of households continue to utilise different products to meet household needs. The most widely used products are fuelwood, wild herbs and wild fruits. More so, my results revealed a significant increase in the number of people commercialising natural resource products over the past fifteen years. Furthermore, I found that rural livelihoods in Fairbairn are heavily dependent on external income and consumption and have become increasingly divorced from local production patterns. My results depict a steady decline of cultivated fields with a corresponding increase of home gardens since the 1960s. Therefore, the results demonstrate that current livelihood strategies are an expression of historical processes interacting with current contextual complexities. Given the complex and multidimensional issues at play in Fairbairn, the study highlights that there is no straightforward answer regarding future livelihood strategies. However, participatory scenario deliberations revealed that the youth were much more open to diversified and even very different forms of livelihood strategies in the future, whilst community leaders and elders remained firmly attached to farming activities. Understanding the diversity of past livelihood changes, together with current trends, can help to better contextualise future livelihood trajectories and this can therefore help rural communities identify and avoid undesirable futures under a changing climate.
