- Description: The aim of this treatise with the title Labour dispute resolution in South Africa and Malawi: A comparative study is to compare alternative dispute resolution between these two countries. It, furthermore, aims at drawing best practice to feed into each other. Another objective of this treatise is to learn by comparing and providing insight into the two countries’ alternative dispute resolution systems. This treatise comprises five chapters, each dealing with different aspects of alternative dispute resolution and an inter-country comparison. Chapter 1 introduces the concept of alternative dispute resolution and explains different types of methodologies in South Africa and Malawi in this regard. It also describes the different external alternative dispute resolution systems. In any conflicting situation, there is no guarantee that disputes will be resolved successfully, hence, one needs to apply different methodologies to try to resolve disputes, such as an alternative dispute resolution. Chapter 2 examines the Alternative Dispute Resolution System of South Africa and consists of three parts. Part 1 focuses on the historical legislative framework, Part 2 examines labour dispute resolution, as provided for in the Labour Relations Act of 1995 and Part 3 analyses the advantages and disadvantages of alternative dispute resolution systems in South Africa. Alternative dispute resolution has become popular and prominent across the globe as it ensures privacy and emphasises a cooperative and constructive way forward, which carries with it the possibility of improving employment relations in the long term. Chapter 3 provides an outline of Malawi’s relevant dispute resolution legal framework, regulated methodologies and system. Chapter 4 concentrates on evaluating and comparing alternative dispute resolution systems in South Africa with that of Malawi and later evaluates efficiencies, the effectiveness and challenges of alternative dispute resolution, which arise from the earlier comparison, with the aim of determining whether or not there is a need for reform of each country’s alternative dispute resolution system. The delivery of alternative dispute resolution systems can take place in a number of different settings, such as an employment tribunal, under the auspice of the Ministry of Labour, dispute resolution boards or a private dispute resolution. However, for the purpose of this study, the main mechanisms that will be analysed are arbitration, conciliation and mediation. Conclusions and recommendations are discussed in Chapter 5, which briefly summarises this study and synthesises the analysis of the South African and Malawian alternative dispute resolution system. Recommendations for legislation, methodologies and systems are also made.

- Description: Point-of-care ultrasound (POCUS) is a fast-growing clinical utility and is becoming an essential clinical skill for all practitioners attending to critically ill patients. Ultrasound equipment is now smaller, more affordable and readily available in clinical work areas. POCUS is performed by a non-cardiologist physician at the patient’s bedside as an adjunct to the physical examination. It is easily taught, non-invasive and allows for real-time clinical information. Bedside use of ultrasound imaging aids with rapid diagnosis of severe and life-threatening pathological conditions. It can be repeated, may change clinical management, and impact on patient outcome. POCUS has a broad clinical use, including, but not limited to, focused assessed transthoracic echocardiography (FATE), lung ultrasound imaging, extended focused assessment with sonography for trauma (e-FAST), vascular access and regional blocks. It may also be extended to detect endotracheal intubation and the estimation of intracranial pressure. Assessment of cardiac pathology by POCUS, performed by a novice examiner, has been shown to compare with the gold standard of an expert. Training is paramount. The physician should know his limitations and always relate the information back to the clinical scenario and context. By incorporating POCUS as part of our armamentarium and into our daily medical practice, we might see it reach its full clinical potential, optimising patient care and improving patient outcomes.

- Description: Fishers make an important contribution to the global economy and add value to a country’s gross domestic product. Their contribution is even more important in countries such as Namibia that rely heavily on the fishing industry as a source of income. The working conditions of fishers have recently come under scrutiny as a result of poor labour standards when compared to employees ashore. A background of the working conditions of fishers is provided illustrating the unique working conditions of the fishing industry. After that the international standards, namely those of the United Nations and the International Labour Organisation (hereinafter referred to as “the ILO”), are discussed and the challenges in the regulations of the condition of employment of fishers are pointed out. The ILO recently adopted the Work in Fishing Convention (hereinafter referred to as “the WIFC”) in 2007, which is the primary instrument applicable to fishers’ conditions of employment. Namibia has not ratified the Convention and, as a result, it has no legal obligation to comply with the standards it sets. The international standards were tested against the national legislation of Namibia. This was done to determine the extent of Namibia’s compliance with those standards. The dissertation revealed that, if Namibia were to immediately ratify the Convention it would not conform with the standards and, as a result, would be in breach of its international obligation. The dissertation takes a step further by comparing the approach taken in regulating the conditions of employment in Namibia to the approach taken in South Africa. The purpose of the comparison is to determine the lessons Namibia can learn, if any, to improve the regulation of the condition of employment for its fishers. The dissertation 7 reveals that there are lessons Namibia can learn from South Africa to improve the conditions of employment of the fishers. These lessons relate to introducing a bargaining council and, where necessary, statutory councils for the fishing industry. The introduction of a bargaining council and statutory councils would give organisations such as trade unions more power to negotiate a general standard across multiple sectors within the fishing industry. The standards that are negotiating could incorporate the standards provided in the WIFC even though Namibia has not ratified the convention.

- Description: Information Communication Technology (ICT) is becoming popular especially within a university campus setting not only as a learning tool but also for the purpose of communication. Internationally there is an acknowledgement of the popularity of ICT in delivering mental health services. This study is built on that premise which indicates that ICT could serve as a viable tool for counselling interventions within a university setting. However, limited research has been done in this area and conflicting results have been reported especially related to gender. This study therefore aimed at exploring the intentions and attitudes of male and female students towards using ICT for counselling at a South African university. A quantitative research approach was employed to collect and analyze data. Data was collected amongst students using self-administered questionnaires with a sample of 266 (N = 266) respondents. Descriptive and inferential statistics were employed. The main findings of the study indicate that students have an intention to seek psychological help through the use of ICT counselling, which consequently positively influenced attitudes towards the utilization of ICT counselling. Results further indicate that gender and age differences amongst university students is significantly related to the intention to use ICT counselling. The information generated from this study has contributed to the limited body of literature on ICT in counselling psychology, more specifically in a university setting in South Africa. Overall, it encourages critical reflection on modern psychological practice to meet student’s needs.

- Description: In 1913 in South Africa the natives of land act during apartheid resulted to the separation of South Africa. South Africa was divided into two areas where they were black and white areas. This act had a rule that said the black people can only move out of their lands only if employed as labourers by the whites. The white population was one-fifth of the population and was given 92.5 percent of the land while the rest of the population were blacks and they were restricted to stay on the 7.5 percent of land. In the Eastern Cape, two homelands were created: the Transkei (in 1951) and the Ciskei (in 1961). In 1963 the Transkei became the first homeland to be granted the status of 'self-governing territory within the Republic of South Africa’, with the Ciskei following suit in 1972. The apartheid policies caused economic failure and corruption because very little economic and infrastructural development took place in the homelands. According to the ‘legacy perspective’: the former homelands are historically-determined structural poverty traps. The objective of the study is to describe the extent and change of economic function/role of Ngcobo town and linkages with its surrounding villages. Availability or convenient sampling and random sampling techniques were used to collect primary data from farmers and surrounding villages. Descriptive statistics was used to profile farmers as well as the participants in the surrounding villages. Descriptive statistics was used to describe the change in the economy of Ngcobo town and the change in the economy of the surrounding rural areas. Households in the former homelands devote a large share of their total expenditure to food and beverages, and yet it would appear that a relatively small share of this food originates from these same rural areas. The point of departure of this report is the observation that rural areas are diverse, whereby some areas within the former homeland areas in particular exhibit signs of dynamism which are not understandable in terms of the ‘legacy perspective’.

- 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: South African National Parks (SANParks) manages 19 functional national parks (NPs) and oversees the conservation of South Africa’s (SA’s) biodiversity, landscapes and heritage assets. The organisation plays a significant role in the promotion of SA’s nature-based tourism business which in turn forms part of the nation’s heritage and identity. Tourism to SA’s NPs is significant and interest in visiting these parks continues to increase annually, from both international and domestic markets. Three of these NPs are located in the Eastern Cape province, namely Addo Elephant National Park (AENP), Camdeboo National Park (CNP) and Mountain Zebra National Park (MZNP) and were the focus of this study. The main reason for conducting the current study was to establish what factors make visits to the three aforementioned NPs memorable. The findings of this research could be useful to all NPs and assist them in making decisions regarding the evaluation and creation of product offerings that will enhance experiences and make them memorable for tourists. Based on the findings, and because each NP is unique (for example, the different biodiversity and landscapes), the product offerings can also be made exclusive to each NP and therefore tourists can have the opportunity for different MTEs in each park. Providing product offerings that afford MTE opportunities are particularly important for NPs, as government funding is decreasing and each NP needs to generate its own funds. Tourism is presently the economic lifeline for the parks. If NPs focus on improving current products where necessary and developing new products that provide for MTEs, NPs could increase their competitive advantage. Having a competitive advantage can ensure an increase in tourism numbers and therefore the financial sustainability of the park. Data was collected on site at each of the three NPs selected for the study, using convenience sampling to select respondents. A web-based survey was also posted on the SANParks’ website. Prior to the posting of the web-based survey, SANParks conducted a simple random sampling procedure utilising a sampling frame of tourists who had previously visited the respective NPs. The selected target population emanating from simple random sampling was e-mailed the link to the SANParks website which guided respondents to the online questionnaire if they wished to take part in the survey, hence the response sample was a convenience sample. In total, 463 usable questionnaires were received. Descriptive statistics resulted from the data analysis. A frequency analysis showed the distribution of the results, while an exploratory factors analysis (EFA) was conducted to ascertain any latent factors in the data. The results of the EFA showed the presence of three latent factors which were labelled Pleasure, Social Interaction and Discovery and Enrichment. Firstly, a strong positive correlation was shown between two of the factors, namely Pleasure and Discovery and Enrichment, and secondly, a positive correlation between two other factors, namely Social Interaction and Discovery and Enrichment was indicated. A weak correlation was shown between the factors Pleasure and Social Interaction. This research has contributed to the knowledge base regarding the factors that make a visit to AENP, CNP and MZNP memorable. Future research can make use of these factors for more exhaustive research in a wider range of NPs.

- Description: In this study, a facile synthesis method was developed to produce layered-layered cathode materials with the formula xLi2MnO3•(1-x)LiMO2 (M= Ni and Mn) referred to as lithium-manganese-rich materials for lithium ion batteries. The prepared materials displayed high capacity ≥200 mAh/g at a current density of 20 mA/g in the voltage range of 2.0 V to 4.8 V. In particular the cathode material prepared at pH 10.0 delivered a high initial discharge capacity of 266 mAh/g at 20 mA/g current density and maintained a discharge capacity ≥220 mAh/g at 50 mA/g after 50 cycles. The synthesis method was used to further investigate the effect of lithium ratio in the layered-layered material. Li1+xMn0.6Ni0.2O2, x= 0.2, 0.25, 0.3 and 0.4 cathode materials were produced respectively. The BET surface area analysis results showed that Li1.3Mn0.6Ni0.2O2 material had comparatively higher surface area to the other cathode materials and also delivered good electrochemical results. XPS showed that the cation distribution is affected by the increase in lithium ratio, the Mn4+ percentages decreased significantly with an increase in lithium ratio. All materials peaks deconvoluted into two peaks namely Mn4+ and Mn3+, Li1.3Mn0.6Ni0.2O2 had the highest percentages of the stable Mn4+ 70.8%. Further investigation focused on the effect of the sintering temperature on the structure and the electrochemical performance of Li1+xMn0.6Ni0.2O2, x= 0.25, 0.3 and 0.4 cathode materials. X-ray diffraction showed the same patterns for all cathode materials sintered at 700˚C, 800˚C and 900˚C. Rietveld refined results however, showed that the increase in the sintering temperature, results in a decrease in the Li2MnO3 component percentage in the layered structures. Scanning electron microscopy images further proved that the particle size increases with increasing temperature. The charge–discharge tests of coin cells demonstrated that the materials sintered at 800˚C delivered higher discharge capacities above 200 mAh/g at 20 mA/g current density when compared to the materials made at the lower temperatures. Lastly the cathode material prepared at pH 10.0 was further evaluated in a cell using lithium titanate oxide Li4Ti5O12 as anode material. The cells delivered an initial discharge capacity of 213 mAh/g at 20 mA/g within a voltage range 3.3V-0.5V. The coin cells developed in this work delivered good cycling performance.

- Description: Orientation: Several policies have been formulated by the government to redress the inequalities of apartheid. However, the policies have not yielded any positive results as many graduates from Historically Disadvantaged Institutes (HDIs) continue to struggle in the open labour market as compared to graduates from Historically Advantaged Institutes (HAIs). This has been mainly attributed to the legacy of apartheid in several previous studies. As a result, most of these previously disadvantaged individuals (mostly Black Africans) struggle to make the transition from higher education into the world of work. Research Purpose: This study thus explores the journeys of these Black African students from HDIs to understand the transition and experiences from tertiary education into the labour market. Further, the research sought to understand how these transitions and experiences manifest in a context of high unemployment. Finally, the resolution tactics used by students in such a context are given attention. Research approach, design and method: A longitudinal qualitative approach was deemed appropriate for the study as the aim was to understand the changes that occurred over time. The data was collected over a two-year period. A narrative inquiry was utilized as it allowed the participants to share their perceptions without limitations. A total of 30 participants partook in the study. The participants were selected using a purposive sampling to ensure the right participants were involved in the study. The main criteria for selection to participate was that the participants had to be enrolled with a HDI. Main findings: The narratives of the participants led to the formulation of six main themes that were regarded as affecting the transitions and experiences of the Black graduates from HDIs; namely, (1) socio-economic background, (2) education system, (3) labour market experiences, (4) geographical location, (5) social capital and (6) student resolutions to the challenges of employability. A previously disadvantaged background resulted in the participants being recipients of poor education quality, no social networks or information to navigate the labour market and limited access to the labour market due to secluded residential areas. Subsequently, most participants were unable to take responsibility of enhancing their own employability. Contribution: It is not the sole responsibility of the higher education institutes to produce employable graduates, but it's a process that should also involve government, students and employers. As long as the social inequality remains an issue in the country all the efforts to improve employability and transition into the open labour market will be in vain. Furthermore, employers must work together with higher education institutes by offering programs such as internships and career expos to enhance the employability of the graduates. A Graduate Transition Model (GTM) is suggested based on the findings of this research.

- Description: Partnership between schools and parents seems to substandard, leading to both parties questioning each other on why children underperform. Most parents view the school as an instrument for the achievement of children and parents with limited or no education may have little or no interest in supporting children’s academic work. The aim of this study was to investigate how parental involvement in children’s academic work can be enhanced. It focused on three rural secondary schools in the Amathole West Education District in the Eastern Cape Province of South Africa. The study particularly investigated how school schools involved parents in children’s academic work and how they, together with principals, teachers and learners view their involvement in children’s academic work. Guided by Epstein’s theory of parental involvement, this qualitative study was premised on the interpretative paradigm. Face to face interviews and focus group discussions were used to collect data from three high schools in the Amathole West Education District. Purposive sampling was used to select participants who comprised a target population of 24 participants. It emerged from the data that although schools were trying to involve parents in children’s academic work, their activities were uncoordinated, occurred at school level rather than classroom level and focused less on learners’ academic work. Parent’ involvement in their children’s academic work was not touching the real curriculum issues; rather it touched on the outside. The data also showed that parents’ academic statuses influenced their participation as those who had little education seemed to be reluctant to participate on academic issues. The study concludes that there was lack of coordinated strategies by schools to involve parents in children’s academic work. The study, therefore, recommends that Coordinated Grade-based Parent-Teacher Forums be established. This will assist in opening a planform for teachers and parents to engage on teaching and learning discussions and curriculum debates.

- Description: Hidden Markov Models (HMMs) have become increasingly popular in animal movement studies as they provide a flexible modelling approach and take the correlation between successive observations into account. They can segment the movement paths into latent states, which can be considered as rough proxies for the behaviours of the animals. This study comprises of two sections, both involving the application of HMMs to large terrestrial mammal movement data. Usually step lengths representing the displacement distances between successive observations, turning angles measuring the tortuosity, or a bivariate input of both variables are used as inputs in the models. It has been found in the literature that the turning angle is either included in the modelling process or it is excluded without much justification for doing so. The first part of this study investigates the nfluence of the turning angle on the model output and resultant interpretations of the HMMs when modelling the trajectories of large terrestrial mammals in southern Africa. Results revealed at different time scales, and for both predator and herbivore species in this study, that the turning angle does not influence the state allocation of the HMMs, which is the main output in terms of interpreting the behaviours of the animals. It is thought in most cases that the inclusion of the turning angle overcomplicates the models unnecessarily without contributing any additional information in terms of the behavioural interpretations or improving the overall fit of the models. This was found for the variety of movements of the species under observation in this study. The second part of this study attempts to validate the state allocation of the HMMs fitted to eland trajectories in the Greater Addo Elephant National Park in the Eastern Cape, with the use of camera trap data. This presented a unique opportunity as this type of data is mainly used for abundance or capture-recapture studies, and the HMMs are rarely validated as the true behaviours of the animals are seldom known. Results revealed that the same diel patterns were detected by the HMMs that were shown by the classified camera trap data. Direct comparisons of the observations where the dates and times matched for the telemetry and camera trap data could be done in several rare instances, which revealed many similarities. Although it was not an ideal comparison, the camera trap data provided a rough validation of the state allocation of the HMMs used in the study.

- Description: This study evaluated the carcass and meat quality traits of spent laying hens as influenced by production systems (conventional cages and free range) and the inclusion/exclusion of canola meal in their diets. A total of 30 free range and 60 battery cage reared Lohmann Brown-Elite spent laying hens were obtained from a commercial egg producer. The 30 free range hens (53 weeks of age) and 30 of the caged hens (40 weeks of age) were fed a conventional diet, while the remaining 30 caged hens (48 weeks of age) were fed a diet supplemented with canola meal (20 percent). Carcass, portion and organ weights were determined. Physical attributes and proximate composition were analyzed for, with additional fatty acids and sensory profiles being determined for the effects of canola meal inclusion in the diet. Caged hens had heavier (P ≤ 0.05) warm and cold carcasses, thigh, wing and feet compared to free range hens. The percentages of the breast (26.1 ± 0.51 vs. 28.3 ± 0.28), drum, breast bones, breast thaw and cooking losses and thigh cooking loss were lower (P ≤ 0.05) for caged hens than for free range hens. Free range hens had heavier (P ≤ 0.05) gizzards (33.9 ± 1.04 vs. 30.5 ± 0.73) and bones and a lower (P ≤ 0.05) breast meat percentage (47.3 ± 0.94 vs. 51.7 ± 1.35). Meat redness (a*) (0.54 ± 0.222 vs. 1.40 ± 0.135) and hue angle value, skin redness (a*), breast and thigh, Warner-Bratzler shear force (WBSF) values (breast: 12.37 ± 0.411 vs. 17.10 ± 0.751, thigh: 29.68 ± 0.306 vs. 39.75 ± 0.826), breast moisture and thigh ash content were lower (P ≤ 0.05) for caged hens than free range hens. Caged hens had higher (P ≤ 0.05) thigh thaw loss and breast ash content than free range hens. Canola-fed hens had higher (P ≤ 0.05) drum percentages, breast bone weights and percentages, with lower (P ≤ 0.05) thigh and breast meat percentages. Canola-fed hens had lower (P ≤ 0.05) thaw losses, skin yellowness (b*) and Chroma values, breast fat content with higher cooking losses, skin redness (a*) and hue angle value, as well as breast WBSF (12.37 ± 0.411 vs. 15.43 ± 0.600). Palmitic acid, stearic acid, heneicosanoic acid acid, palmitoleic acid, saturated fatty acids (SFA) (34.0 ± 0.56 vs. 38.7 ± 0.71), n-6:n-3 polyunsaturated fatty acids (PUFA) ratio (5.5 ± 0.13 vs. 7.2 ± 0.28), atherogenic index (IA), thrombogenic index (IT), delta-5 desaturase (D5D, elongase index and thiosterase index were lower (P ≤ 0.05) for canola-fed hen breast meat. Breast meat from conventionally fed hens had lower (P ≤ 0.05) myristic acid, lignoceric acid, nervonic acid, alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), PUFA:SFA ratio (0.7 ± 0.05 vs. 0.9 ± 0.02), n-3 PUFA (3.4 ± 0.31 vs. 5.1 ± 0.17), hypocholesterolemic:Hypercholesterolaemic (h/H), stearoyl-CoA desaturase 16 (SCD16) and stearoyl-CoA desaturase 18 (SCD18). The breast meat from conventionally fed hens had lower (P ≤ 0.05) metallic flavor than that from canola-fed hens. Strong positive correlations were observed for overall aroma with chicken (r = 0.965, P < 0.001) and brothy aroma (r = 0.827, P < 0.001); overall aroma with overall flavor (r = 0.680, P < 0.001), chicken flavor (r = 0.668, P < 0.001) and brothy flavor (r = 0.548, P = 0.006); initial juiciness with sustained juiciness (r = 0.771, P < 0.001) and tenderness (r = 0.537, P = 0.007); sustained juiciness with tenderness (r = 0.790, P < 0.001) and chewiness with residue (r = 0.783, P < 0.001). Whilst strong negative correlations were observed for: sustained juiciness with chewiness (r = -0.655, P = 0.001) and residue (r = 0.783, P < 0.001) and for tenderness with chewiness (r = 0.845, P < 0.001) and residue (r = -0.855, P < 0.001). Results of this study highlight that a free range production system when compared to a conventional cage system increased undesirable carcass and physical meat traits of spent laying hens. On the other hand, canola meal inclusion incorporates beneficial health aspects without affecting the sensory profile of meat derived from spent laying hens, both groups of hens being reared in battery cage system. Spent laying hen breasts can be consumed as a functional food (especially canolafed) since the fat content and composition was observed to be close to that which is recommended for a healthy diet.

- Description: The study aimed to assess beneficiary perceptions regarding farm worker equity share schemes in South Africa. Farm worker equity share schemes started in the early 1990s with the aim of having a special arrangement pertaining to the ownership and operation of a farm between the farmer and the farm workers. This was intended to assist farm workers in not only remaining as farm workers but also to gain ownership of the farm. This could lead to the empowerment of farm workers, better working conditions, improved living standards and their rights to land ownership. Farm worker equity share schemes have been widely reported as having failed to meet their intended objectives, thus, in 2009, the Department of Rural Development and Land Reform initiated a study to assess the implementation of equity share schemes. Although the report was not made public, it reports that out of the 88 equity share schemes at the time, only nine managed to pay dividends ranging from R200 to R2000 per year. As a result, the Department of Rural Development and Land Reform put a moratorium on equity share schemes; this was however removed in 2011. It is against this background that this study was undertaken to assess beneficiaries’ perceptions regarding farm worker equity share schemes in South Africa. A positivistic research paradigm was employed in this study, by means of quantitative research. Secondary data in the form of textbooks, journal articles and Internet sources provided the theoretical framework for this study. Primary data was obtained using the survey method, by means of self-administered structured questionnaires. Convenience and purposive sampling were applied in order to select 20 farms that use equity share schemes. The farms selected for this study were located in the Eastern Cape, Gauteng, Mpumalanga and the Western Cape provinces, covering a variety of farming activities such as citrus fruits, crops, vegetables and wineries. Ideally, a total of 15 farm workers per farm were targeted. However, due to a variation in these farm worker equity share schemes, on some farms less than 15 workers and in others more than 15 workers were selected for the study; this resulted in a total sample size of 341 farm workers. Ten null-hypotheses and a hypothetical model of beneficiary perceptions regarding farm worker equity share schemes were tested. The influence of seven independent variables were tested, these are: stakeholder trust, operational risks, government interventions, two-way communication, farm worker empowerment, training and skills development, and access to resources on farm worker equity share schemes. In addition, the influence of farm worker equity share schemes on three dependent variables, namely, farming performance, sustainability and employee expectations were tested. The Statistica (version 13.2) computer programme was used to analyse the results by means of advanced statistical techniques (such as exploratory factor analysis, regression and correlation analyses) as well as descriptive analysis and frequency distributions. After various statistical procedures, the model was re-specified; some of the variables were then renamed and the hypotheses were adjusted accordingly. The empirical results showed that three key variables to the success of farm worker equity share schemes are stakeholder trust, government interventions and farm owner support. It was determined that these key variables could lead to increased farming performance, farming sustainability and meeting employee expectations. This study provided useful and practical guidelines to farm owners and administrators of equity share schemes, so as to ensure effective strategising that could enhance their competitiveness and long term survival. The findings of this study could inform strategy policy formulation and implementation in the agricultural sector, as pertaining to farm worker equity share schemes. The study used a sound and well-developed research design and methodology, which has been justified and successfully applied to this research; this method can be utilised by other similar studies to conduct empirical research in the field of farm worker equity share schemes. It is envisaged that the results and recommendations of this study could be used to implement effective strategies that could ensure the effective functioning of farm worker equity share schemes in South Africa.

- Description: The purpose of this research was to explore the relationship between organizational culture and organizational performance in a manufacturing company. This company supplies metal products to the motor vehicle manufacturing industry, where the quality and quantity of parts produced is of paramount importance, since the buyers of these products are quality conscious. The organization has three production shifts that rotate each week. Anecdotal observations are that irrespective of the time that a shift operates over the course of the month, the different shifts tend to perform at different levels in terms of quality and quantity of output. This study therefore sought to investigate if these differences between shifts are statistically significant, and if so, whether these shifts also have differences in organizational culture. Components of organizational culture include values, norms, beliefs, attitudes, principles and expectations that give the organization a unique personality and differentiate it from other organizations. While the literature indicates that qualitative or quantitative approaches can be used in organizational culture research, this research adopted the quantitative approach, making use of the Competing Values Framework (CVF). The CVF is a four-category organizational culture typology established by Cameron and Quinn (2006). The framework is based on two dimensions: stability or flexibility of the organization, and external or internal focus. In this research, the CVF was used as a measurement tool to evaluate organizational culture. In order to determine differences in organizational culture between shifts, a survey was undertaken (N=138) which measured employee perceptions pertaining to the existing organizational culture of each of the three production shifts at the company. Secondly, differences in performance between the shifts were examined by using the performance data for a three-month period for each shift in terms of quantity and quality. This data was obtained from the management of the production process at the company. Statistical analysis was done using ANOVA to analyse the differences between the shifts. The findings indicated that the dominant existing organizational culture at the company under investigation is a clan culture. Furthermore, there is a statistically significant difference between the cultures of all the three shifts at the manufacturing company. The results also indicated that there is a statistically significant difference in the quantity and quality of production between the three shifts. In conclusion, the research indicated there are differences in culture and in performance, but given the nature of the data, it was not possible to statistically analyse the relationship between shift culture and performance. However, it is conceivable that cultural differences between shifts may be contributing to performance differences. With regards to further research, it is recommended that this research be extended to other branches of the manufacturing company in other regions, in order to determine whether there are any significant differences in culture and performance between these branches and their shifts. Research could also be extended to other South African organizations to create a sufficiently large sample of shift and/or business units, so as to be able to do statistical analysis of the relationship between culture and performance.

- Description: The South African disease profile has changed significantly and has increasing prevalence of overweight and obesity in relation to body mass index. Type 2 diabetes mellitus is greatly associated with increased body mass index and poses a great health concern for women of childbearing age. Complications of type 2 diabetes mellitus in pregnancy has life-threatening for the mother and baby. South African women have a tendency of avoiding and neglecting routine screening before pregnancy, that is part of preconception care or internatal care. The aim of the study sought to identify women of childbearing age with predisposing factors of type 2 diabetes, in order to intervene, using a lifestyle modification to delay and prevent the occurrence of type 2 diabetes. A quantitative intervention study using parallel group randomized control trials was used. One hundred and forty-six women of childbearing age (18-45 years) were recruited and assigned to either control (n=73 + 9) or experimental group (n=73 +9). using a computer software randomizer application to avoid bias in selection of participants by the researcher. Both groups received health education from the researcher and the dietician from hospital. The control group had no intervention done, whereas the experimental group attended physical activity sessions which were administered by a hired lay coach. The findings showed that both groups are at risk of developing type 2 diabetes although they both groups lose weight. The weight loss of the control group was owed to education during recruitment. Vegetable consumption was minimal to the younger age group than the older age groups. Waist circumference above 105cm consumed less vegetables, a higher waist circumference is associated with insulin resistance. There was also minimal exercises and knowledge about the preconception care. Diabetes prevention is vital for the women of childbearing age as it affects both mother and child. The study recommends lifestyle modification (exercise and healthy diet) to prevent and delay of type 2 diabetes and gestational diabetes mellitus. The study also recommends Preconception care and Re- engineering of Primary health care uses community health care workers for screening high risk women during home visits.

- Description: With the substantial number of new malware variants found each day, it is useful to have an efficient way to retrieve Indicators of Compromise (IOCs) from the malware in a format suitable for sharing and detection. In the past, these indicators were manually created after inspection of binary samples and network traffic. The Cuckoo Sandbox, is an existing dynamic malware analysis system which meets the requirements for the proposed framework and was extended by adding a few custom modules. This research explored a way to automate the generation of detailed network-based IOCs in a popular format which can be used for sharing. This was done through careful filtering and analysis of the PCAP hie generated by the sandbox, and placing these values into the correct type of STIX objects using Python, Through several evaluations, analysis of what type of network traffic can be expected for the creation of IOCs was conducted, including a brief ease study that examined the effect of analysis time on the number of IOCs created. Using the automatically generated IOCs to create defence and detection mechanisms for the network was evaluated and proved successful, A proof of concept sharing platform developed for the STIX IOCs is showcased at the end of the research.

- Description: While many governments and organisations across the globe have programmes in place to control flood disasters, the challenges, unpreparedness and vulnerability to flooding in many parts of the world persist. This study used the low-lying area of Missionvale township in Nelson Mandela Bay, Eastern Cape, South Africa as a case study to investigate the extent of the vulnerability of informal settlement dwellers to flooding, and to understand how the community deals with and recovers from severe flood disasters. The study adopted both quantitative and qualitative research methodologies. The empirical data for the study was obtained through a survey of 90 residents of the area, as well as interviews with the members of the community. Fieldwork and observations were also conducted. These focused on examining the area in terms of disaster relief. Secondary data was obtained through a literature review as well as a review of legislative frameworks. The findings indicate that since 1994, the government has put in place a disaster management system but the system still needs to be reinforced as periodic severe flooding continues to destroy properties and infrastructure in many communities. Crime as well as the emergence of water-borne diseases are negative spin-offs of these disasters. The research elaborates on the coping strategies of the community to floods and makes recommendations on vulnerability and coping strategies to floods in low-income settlements in South Africa. With climate change likely to aggravate flood disasters, it is recommended that the policy directions need stakeholders to improve disaster preparedness, provide flood measures to houses and storm water drainage, develop early warning systems and improve community participation in disaster preparedness planning and efforts. In addition, it is crucial to improve post-disaster responses such as service delivery and support for the flood victims with needed resources and rebuilding of homes and lives.

- Description: In post-development theory, ubuntu is often cited as an example of an “alternative to development”. This article investigates whether ubuntu can play this role and what to think of the demand for alternatives to development in general. In order to do this, the paper fi rst deals with central aspects of postdevelopment theory and the debate about ubuntu. Although the concept fi ts well into a post-development perspective, the attempts to contrast ubuntu with Western ideas and ways of life are often fueled by the desire to rekindle an original, pre-colonial, authentic African philosophy. Yet discourses on Africa are always embedded in Western discourses, so this opposition reproduces precisely those dichotomies it aims to fi ght. More generally, this also holds true for the idea of “alternatives to development”, which postulate an essential opposition to “development”. This, however, denies claims for equal rights and participation at the root of demands for “development”. The struggle for these claims cannot be fought beyond the existing global order. Instead of engaging in romanticizing projections about an Africa beyond “development”, people’s views and needs should be taken as the starting point for the struggle against injustice and inequality.

- Description: A total of 141 Polydactylus quadrifilis were sampled from the Kwanza Estuary in Angola ranging in size from 436 to 1360 mm fork-length (FL). Of these, 124 were male, six intersex and 11 female. Female fish were significantly longer (mm, FL) and heavier (kg) than males and had significantly higher gonadosomatic indices (GSI’s) than those of males and intersex fish. Transitional (intersex) gonads were delimited, with testicular and ovarian regions separated by connective tissue. The first signs of ovarian tissue appeared on the outer ventral surface of the gonad. A second layer of ovarian tissue was first noticeable at either end of the initial ovarian region and developed back towards the centre of the ventral wall to form a luminal space. Early-stage oocytes were commonly found in the outer area of male regions and residual late-stage spermatids and spermatozoa were found in the luminal space of ovarian regions, suggesting a process of sex change from the outside inwards. A loss of male function was noted with increased ovarian prevalence. Based on this evidence it is suggested that P. quadrifilis in the Kwanza Estuary are protandrous. Owing to the reliance of P. quadrifilis on large highly fecund females for egg production, it is likely that they will be sensitive to fishing practices that target larger individuals within the population.

Transitional (intersex) gonads were delimited, with testicular and ovarian regions separated by connective tissue. The first signs of ovarian tissue appeared on the outer ventral surface of the gonad. A second layer of ovarian tissue was first noticeable at either end of the initial ovarian region and developed back towards the centre of the ventral wall to form a luminal space. Early-stage oocytes were commonly found in the outer area of male regions and residual late-stage spermatids and spermatozoa were found in the luminal space of ovarian regions, suggesting a process of sex change from the outside inwards. A loss of male function was noted with increased ovarian prevalence. Based on this evidence it is suggested that P. quadrifilis in the Kwanza Estuary are protandrous. Owing to the reliance of P. quadrifilis on large highly fecund females for egg production, it is likely that they will be sensitive to fishing practices that target larger individuals within the population.
