- Description: The purpose of this research study was to investigate the effects of disruptive innovation on MTN telecommunication strategy in Africa. The goal of this research study was to investigate the effects of disruptive innovation on MTN telecommunication strategy in Africa. Five independent variables were identified and tested as to identify the effects/ impact they have on the MTN telecommunication strategy. The research report began with an in-depth literature review on the concept of disruptive innovation and the variables and Internet of things, Cloud Technology, Blockchain, Mobile Money Cashless Society and Big Data. The literature review also provides an overview of the status of the telecommunication industry in Africa, the pace of change and the challenges network operators are facing due to the innovations. This is followed by qualitative explanatory case study research design through in-depth interviews. The research provides valuable insights on recommendations to MTN management on the effects on disruptive innovation on their strategy. This research study provides a useful insight on the effects of disruptive innovation with a telecommunication context in Africa. It also highlights the key disruptive technologies that are at the forefront the current innovation wave. The study is limited to MTN and does not incorporate other multinational network operators who have established networks on the African continent. The research effort looks at the positive and negative effects of disruptive innovation on MTN strategy and make recommendations on how MTN can overcome, minimise or reduce the identified effects on the strategy.

- Description: The main aim of this research is to examine the hip hop scene in Grahamstown, Eastern Cape and whether hip hop can serve as a significant platform to discuss women’s lived experiences. This study also places focus on how female rappers construct their rap personas, as well as how they are perceived by their male counterparts. In order to understand the multifaceted viewpoints, it was necessary to interview both male and female hip hop artists. Eight interviews were conducted with eight young black rappers who are actively involved in the Grahamstown hip hop scene. It was found that hip hop, like any other art form, is a significant platform for women to express themselves, however gender constraints limit who is willing to listen to and promote their music. Male rappers advocate for women to talk about their stories, yet are more unlikely to listen because it does not relate to their struggles. In addition, there seem to be four specific tropes that female rappers choose to construct their identities from. Female rappers tend to create their personas around: Queen Mother, Fly Sista, Bitch with Attitude, and Lesbian. However, these categories are fluid and it was found that women navigate these categories depending on their audience and message they want to convey at a particular moment. Lastly, there is a split between Grahamstown West (Rhodes University) and Grahamstown East (township). University students are unlikely to perform in the township, and township residents rarely perform at organised events in Grahamstown West. In addition, Rhodes University students are more likely to feature on the university run radio station, rather than Radio Grahamstown, the local community radio.

- Description: This study aims to establish Automatic Termination Clauses in Employment contracts by analyzing the provisions of the Constitution of the Republic of South Africa, Labour Relations Act and the precedents. The automatic termination of employment contract means that the contract is terminated without giving an employee the opportunity to state his or her version as per the audi alteram partem principle. In essence, the employee is deprived of his or her right to a fair dismissal as outlined in the Labour Relations Act. The automatic termination clauses in employment contract means that the employment contract will come to an end when the employee’s services are no longer required or when the employer simply does no longer want to keep the employee at work. The Constitution of the Republic of South Africa provides that “everyone has the right to fair labour practices”.1 In terms of the Labour Relations Act (hereinafter referred to as “the LRA”),2 every employee has the right not to be unfairly dismissed. An employment contract between an employee and employer arises out of a contract to perform services. This is so whether the contract is in writing or not. Dismissal is defined in the LRA3 as where the employer has terminated employment with or without a notice. The thesis is composed of five chapters, each of them dealing with different aspects of automatic termination clauses in employment contracts.

- Description: Compliance requirements are part of everyday business requirements for various areas, such as retail and medical services. As part of compliance it may be required to have infrastructure in place to monitor the activities in the environment to ensure that the relevant data and environment is sufficiently protected. At the core of such monitoring solutions one would find some type of data repository, or database, to store and ultimately correlate the captured events. Such solutions are commonly called Security Information and Event Management, or SIEM for short. Larger companies have been known to use commercial solutions such as IBM's Qradar, Logrythm, or Splunk. However, these come at significant cost and arent suitable for smaller businesses with limited budgets. These solutions require manual configuration of event correlation for detection of activities that place the environment in danger. This usually requires vendor implementation assistance that also would come at a cost. Alternatively, there are open source solutions that provide the required functionality. This research will demonstrate building an open source solution, with minimal to no cost for hardware or software, while still maintaining the capability of detecting targeted attacks. The solution presented in this research includes Wazuh, which is a combination of OSSEC and the ELK stack, integrated with an Network Intrusion Detection System (NIDS). The success of the integration, is determined by measuring postive attack detection based on each different configuration options. To perform the testing, a deliberately vulnerable platform named Metasploitable will be used as a victim host. The victim host vulnerabilities were created specifically to serve as target for Metasploit. The attacks were generated by utilising Metasploit Framework on a prebuilt Kali Linux host.

- Description: This study was conducted in Dimbaza, a small town outside of King Williams Town. Dimbaza was created as a resettlement township during Apartheid in 1967. The study investigated local economic development through small businesses. The study described the state of the small business sector, it presented the contribution this sector has towards employment creation and income generation. Furthermore, it investigated the challenges that the small business sector in Dimbaza faces and the level of responsiveness from the local authorities in Buffalo City Metropolitan Municipality which Dimbaza falls under. The study was conducted using a survey questionnaire which was administered to small business entrepreneurs. Furthermore, a focus group with small business owners and semi-structured interviews were conducted with officials from the Buffalo City Metropolitan Municipality in the Business Development and Local Economic Development Directorate. The findings of the study suggest that Dimbaza has a large informal economy which has of survivalist entrepreneurs with small and micro businesses. It is evident from the study that the small business sector in Dimbaza is facing the following challenges: No access to funding opportunities, a lack of infrastructure, lack of proper running water and electricity and lack of economic development programmes from the municipality. There is a dire need for the intervention of local authorities in the small business sector in Dimbaza. Buffalo City Municipality needs to ensure the creation and implementation of programmes through Local Economic Development.

- Description: Peritidal tufa microbialites occurring along the coast near Port Elizabeth, South Africa have been investigated from multiple disciplines and are found to be similar to supratidal tufa deposits in South West Australia. Studies have been conducted on the biological factors, geomorphology, ecosystems, and associated water chemistry. However, to date no mineralogical, micro-fabric, or geochemical analyses have been reported on these tufa deposits. This work, carried out at a previously well-studied area, provides the first study of this kind on the tufa. Chapter 1 is a mineralogical and micro-fabric analysis of the tufa deposits near Port Elizabeth for the purpose of classification and contextualisation. Chapter 2 provides the first geochemical study of these peritidal microbialites. X-Ray diffraction (XRD) investigations reveal dominance of low-Mg calcite in the mineral make-up of the tufa. A micro-structure analysis via thin section exposes a number of fabrics, suggesting various micro-facies: phytoherm boundstone (layered), phytoherm framestone (non-layered), lithoclast, and minor metazoan tufa. Scanning electron microscopy (SEM) images show micro- to nano- scale variation in calcite grains and epitaxial forms of needlefibre calcite (NFC). The elemental composition of the tufa deposits were examined by X-ray fluorescence (XRF), Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS), and Scanning Electron Microscopy / Energy Dispersive X-Ray Spectroscopy (SEM/EDS). XRF and LA-ICP-MS were used to analyse the bulk rock chemistry while SEM/EDS was used to scrutinize specific areas within the tufa. These observations suggest the deposits are better classified as tufa microbialites (rather than exclusively “stromatolites”) and outline similarities and disparities to the micro-fabrics of supratidal tufa deposits in South West Australia, and Cape Morgan, South Africa. Here the Port Elizabeth tufa is shown to be similar, in terms of the dominant elements (O, Ca and to a lesser extent, Mg and Sr), to the Australian deposits despite subtle dissimilarities in water chemistry. Increasing trends toward more marine tufa for many elements are also shown here and can be explained by the interaction with increased amounts of sedimentary products and/or interactions with more saline water that contains a higher TDS (Total Dissolved Salts). This is also the first study to report needle-fibre calcite formation in stromatolites and the first to geochemically analyse modern peritidal microbialites.

- Description: The purpose of the study was to explore the effects of substance abuse on the academic performance and professional behaviour of students at a public nursing college in order to develop guidelines for the prevention of substance abuse. The design that was chosen as most suitable for this study was the qualitative research design. The researcher chose this method as she sought to explore the effects of substance abuse on the participants in this study. A purposive sampling method was used to select participants on the basis of their knowledge of the phenomenon.The participants who were utilised were 3rd and 4th year level students in the four year diploma in nursing. A pilot study was conducted and participants with similar characteristicsto the study population were utilised. Individual interviews were used as the means to collect data during which participants were given an opportunity to discuss issues with the intention of eliciting their views and opinions. One broad, open ended question was used to gather information from the participants and subsequent questions were used to probe further for clarity. Data were collected until saturation pointwas reached. Transcriptions were done within two days of the interview. The researcher repeatedly listened to audio recordings of the data until completely satisfied with verbatim interpretation of data. Data analysis was done manually. The researcher used the process of bracketing during data analysis and remained neutral, setting aside previous knowledge and beliefs about the phenomenon under study. The participants were allowed freedom to conduct their lives as autonomous agents, without control, coercion or exploitation. The findings revealed that: firstly, substance abuse has a negative impact of on both the academic performance and professional behaviour of the public nursing college students; secondly, that guidelines are needed for the prevention of substance abuse amongst students so as to focus on a ‘substance abuse free college environment’. vi The academic performance is negatively affected as substance abuse results in cognitive impairment, failure to meet the 85% lecture attendance requirement resulting in them repeating a year of study or being excluded from the course, and resulting in a missed opportunity to acquire scientific knowledge in nursing. The students’ academic aspirations get derailed. Students also experience strained relationships with lecturers due to drunkenness and bunking classes. Studentlecturer strained relationships are incompatible with academic achievement. Students whose professional behaviour is negatively affected by substance abuse demonstrate unethical conduct and professional misconduct in the clinical setting for experiential learning. The students fail to inculcate the values of the nursing profession and thus tarnish the image of the profession. Such students behave unprofessionally as they either absent themselves from duty, come on duty drunk or continue taking substances while on duty. They are also rude and swear at colleagues, supervisors, other staff members and patients. The students steal from colleagues and display insubordination. Their dress code is unprofessional and they are incompetent with poor standards of care towards the patients. The purpose of this study was to develop guidelines to prevent substance abuse at the college and this has been achieved. The results show that the college environment should be made substance abuse free by: firstly, identifying and mitigating the predisposing factors or reasons for substance abuse, for example: establish a proper and aesthetic infrastructure conducive to learning and teaching at the students’ residences and classrooms, set up mentorship programmes and introduce the house-mother model at residences; secondly, developing a policy on prevention of substance abuse within college premises including disciplinary measures; thirdly, developing stress management programmes for students to prevent abuse of substances as a coping mechanism, e.g. decongest the curriculum, curriculum review to be consultative, develop support groups, grant mid-year breaks and provide recreational and sporting facilities; fourthly, engage the services of a vii professional therapist for students who are already abusing substances or referral to the therapist; fifthly, clinical accompaniment should be strengthened for effective correlation of theory and practice; and, lastly, engage the services of a financial advisor to give guidance on income and expenditure with regard to student stipend instead of spending it on substances.

- Description: Brassica spp. are cultivated all over the world, commercial species include: cabbage, broccoli, kale, kohlrabi and turnip. In this study the focus was on broccoli (Brassica oleracea) production in the Western Cape province of South Africa and its economically important pests and diseases: sugar beet cyst nematode (Heterodera schachtii), diamondback moth (Plutella xylostella), white blister (Albugo candida) and clubroot (Plasmodiophora brassicae), and the different methods to control these pests and diseases. The control methods focused on in this study included a commercial chemical control programme, a biological control programme and a holistic approach. Other factors were bio-fumigation and chemical fumigation and different crop rotation practices including rotation crops versus no rotation crops. The experimental design was a strip split plot design, with different pest and disease management strategies as the main plot treatment and fumigation and rotation treatment combinations arranged in strips across the main plot treatments. The main plot design was a randomized complete block with four programmes (Control, Holistic, Chemical and Biological) replicated four times and laid out in a Randomised Complete Block Design (RCBD). The treatment design of the strip plot factors was a 2x2 factorial with two fumigations (fumigated chemically and fumigated biologically) and two rotations (crop rotated and monoculture) randomly allocated across main plot treatments. Each experimental unit consisted of 40 plants. Plants were evaluated weekly for the incidence of white blister and diamondback moth. Incidences of clubroot and white blister infection of heads of broccoli were recorded 78 days after planting. Baseline soil samples were analysed to establish the soil chemical properties. Post-trial soil samples were also analysed to investigate the effect of the different practices and programmes on the soil chemical properties. Nematodes were extracted pre-trial and post-trial, and the effect of fumigation and crop rotation on plant parasitic nematodes and the nematode population diversity investigated. In the post-trial soil chemical analysis, a significantly higher concentration of Na was recorded for the biological programme when crop rotation was included compared to the no rotation treatment. The concentration of K was also significantly higher in the no rotation compared to the rotation treatment. The nematode results showed very high numbers of bacterial feeders in all the samples. Overall nematode diversity was lacking and showed very few fungal feeders, omnivores and predators. The nematode indices for all of the samples showed that nematodes were highly enriched and unstructured. Of the plant parasitic nematodes, only Heterodera spp. were obtained in the pre-trial analysis, and incidences of these nematodes were lower at the end of the trial. Low numbers of other plant parasitic nematodes viz. Pratylenchus, Paratrichodorus and Tylenchorhynchus were reported for the post-trial analysis of the soil. Because of the low numbers of plant parasitic nematodes, it was not possible to analyse the data statistically. With regard to diamondback moth and the fungal diseases, crop rotation and fumigation did not significantly affect the incidence of white blister and diamondback moth. A significant “days after planting by control programme” interaction was reported for the incidence of white blister on foliage and the incidence of diamondback moth. All three control programmes significantly reduced the incidence of diamondback moth with the chemical programme being significantly more effective than the other two programmes. All three programmes also significantly reduced the incidence of white blister on foliage and the holistic and biological programmes significantly reduced the incidence of white blister on broccoli heads with the holistic programme being significantly more effective than the biological programme. There was no clubroot infection in the trial for any of the treatments. Results of this study showed that it is possible to manage diseases and pests of broccoli using a holistic approach. However, long term trials are needed to confirm the results obtained in this study.

- Description: Brassica spp. are cultivated all over the world, commercial species include: cabbage, broccoli, kale, kohlrabi and turnip. In this study the focus was on broccoli (Brassica oleracea) production in the Western Cape province of South Africa and its economically important pests and diseases: sugar beet cyst nematode (Heterodera schachtii), diamondback moth (Plutella xylostella), white blister (Albugo candida) and clubroot (Plasmodiophora brassicae), and the different methods to control these pests and diseases. The control methods focused on in this study included a commercial chemical control programme, a biological control programme and a holistic approach. Other factors were bio-fumigation and chemical fumigation and different crop rotation practices including rotation crops versus no rotation crops. The experimental design was a strip split plot design, with different pest and disease management strategies as the main plot treatment and fumigation and rotation treatment combinations arranged in strips across the main plot treatments. The main plot design was a randomized complete block with four programmes (Control, Holistic, Chemical and Biological) replicated four times and laid out in a Randomised Complete Block Design (RCBD). The treatment design of the strip plot factors was a 2x2 factorial with two fumigations (fumigated chemically and fumigated biologically) and two rotations (crop rotated and monoculture) randomly allocated across main plot treatments. Each experimental unit consisted of 40 plants. Plants were evaluated weekly for the incidence of white blister and diamondback moth. Incidences of clubroot and white blister infection of heads of broccoli were recorded 78 days after planting. Baseline soil samples were analysed to establish the soil chemical properties. Post-trial soil samples were also analysed to investigate the effect of the different practices and programmes on the soil chemical properties.

- Description: Much of the published malware research begins with a common refrain: the cost, quantum and complexity of threats are increasing, and research and practice should prioritise efforts to automate and reduce times to detect and prevent malware, while improving the consistency of categories and taxonomies applied to modern malware. Existing work related to malware targeting Apple's macOS platform has not been spared this approach, although limited research has been conducted on the true nature of threats faced by users of the operating system. While macOS focused research available consistently notes an increase in macOS users, devices and ultimately in threats, an opportunity exists to understand the real nature of threats faced by macOS users and suggest potential avenues for future work. This research provides a view of the current state of macOS malware by analysing and exploring a dataset of malware detections on macOS endpoints captured over a period of eleven months by an anti-malware software vendor. The dataset is augmented with malware information provided by the widely used Virus. Total service, as well as the application of prior automated malware categorisation work, AVClass to categorise and SSDeep to cluster and report on observed data. With Windows and Android platforms frequently in the spotlight as targets for highly disruptive malware like botnets, ransomware and cryptominers, research and intuition seem to suggest the threat of malware on this increasingly popular platform should be growing and evolving accordingly. Findings suggests that the direction and nature of growth and evolution may not be entirely as clear as industry reports suggest. Adware and Potentially Unwanted Applications (PUAs) make up the vast majority of the detected threats, with remote access trojans (RATs), ransomware and cryptocurrency miners comprising a relatively small proportion of the detected malware. This provides a number of avenues for potential future work to compare and contrast with research on other platforms, as well as identification of key factors that may influence its growth in the future.

- Description: Utilising theories of Communication for Development, the research explores how literacy practices in the homes of a group of working class, English second language parents in Grahamstown are affected by the introduction of new literacy material and insights Furthermore, it discusses how, and through which forms of media, these observed dynamics and changes in practice are best communicated to similar households. The issue of children's literacy development in South Africa is of serious concern, in particular the role that parents play and the level of support they give through home literacy practices. The context is one in which South African children have performed very poorly with regard to literacy levels in international benchmark testing as well as in national assessments. The summary report on the Progress in International Reading Literacy Study (PIRLS) found that some of the factors contributing to these poor results were the lack of reading resources in homes, as well as the lack of strong home-school partnerships in which parents took up the role of co-educators, or even of primary educators at the preschool stage. A group of parents employed by Rhodes University at the Grade 1 - 5 levels signed up to be the recipients of a programme supporting the literacy development of their primary and pre-primary school children. The Intsomi Project is run by the Rhodes Community Engagement Office as part of the Vice-Chancellor’s Education Initiative and provides close to 100 families with weekly reading material and educational games for their children, as well as workshops on the use of these materials and how they might benefit the children. Following a Participatory Action Research approach, a “vanguard” group of parent participants, known as the Intsomi Ambassadors, developed their role as literacy activists, becoming co-creators of media messages that utilised and built on the first stage of their communication within the group. The research explored how the principles and techniques of development support communication, and those of communicative ecologies, could be applied to explore, enhance and disseminate those qualitative changes in behaviour within households that positively affect children’s literacy development. In the process, it aimed to explore whether media representations that reflect the stories of parents trying out new literacy practices can create authentic, endogenous messages that resonate with people in similar circumstances, and can stimulate debate around the issue.

- Description: Multi-drug resistant tuberculosis (MDR-TB) is an ever-growing problem in South Africa (SA). According to the literature, minimal documentation is done on adverse drug reactions (ADRs), specifically in the MDR-TB population. Co-administration of medications is typical for the treatment of drug resistant forms of TB, which leads to high incidences of ADRs during the treatment period, especially in patients with comorbid disease states. This before-and-after study investigated the impact of an intervention (education training presentation and implementation of a purpose-designed documentation tool) on the current documentation pattern in a public sector hospital in the Nelson Mandela Metropole. In order to measure the sustainability of the intervention, the study compared data from the pre-intervention phase to data collected from the post-intervention immediate phase and post-intervention delayed phase. Study results indicated that the intervention appeared to have had a positive effect on the frequency and variety of ADR documentation (2.1 and 1.3 fold increase, respectively) related to MDR-TB by the hospital staff of a public sector hospital, however, the positive change was not sustainable for longer than a three month period post intervention. It is recommended that factors such as: proper adoption; management; and additional resources are required to implement positive changes to documentation practices. Further studies need to be conducted in South Africa regarding the treatment of drug resistant tuberculosis, in order to establish safer treatment guidelines and more promising ADR reporting practices, which will ultimately improve patient care.

- Description: The transport sector is very important in facilitating trade and travel between and within nations. It is at the core of every country‟s economy. In order for transport to play this critical role, this research suggests that it is important for countries to invest in infrastructure. This study examined the impact of transport infrastructure investment on export growth in South Africa for the period of 1994 to 2017. The standard procedure in interpreting the long-run VECM results was applied. All the variables enter the long-run equation significantly, and the signs and magnitudes also appear reasonable. The long run results suggest that transport infrastructure investment have a positive effect on exports in South Africa. As indicated on the long-run equation, transport infrastructure investment is significant in specification; the positive coefficient of the variable in the regression suggests that an increase in investment in the transport infrastructure will lead to an increase in exports. A vector error correction model was estimated with exports, transport infrastructure investment, real effective exchange rate, world gross domestic product, export prices and consumer price index. The variance decompositions show that exports have a high level of inertia in the first year with most of the variations dependent on past export variations. In the second year, employment contributes significantly to variations in exports. Transport infrastructure investment makes very little contribution. Impulse responses show that a positive shock to infrastructure investments increases exports marginally. The results of the study have revealed a number of policy implications that affect transport infrastructure investment and exports. It is highly recommended that government should improve transport infrastructure for all modes of transport as this will lead to an increase in the level of exports in South Africa. Empirical evidence shows that transport infrastructure investment granger cause exports. Government expenditure in transport infrastructure has been considered s one of the means to enhance economic development and transport sector operates as the crucial engine of the economic growth in both developed and developing countries

The study was conducted to determine the benefits and limitation of informal trading in promoting sustainable local economic development in the Intsika Yethu Municipality. South African municipalities for various reasons fail in providing local economic development friendly environment and more developmental and inclusive informal economy policies and by-laws. The objective of the study was to assess the benefits and challenges which might hinder the maximisation of benefits in the sector. The literature was reviewed with the aim to integrate published academic data on the benefits and limitations of informal trading in promoting sustainable local economic development. Data for the study was sourced from the literature and questionnaires administered to respondents who were selected by means of a purposive sampling technique. The respondents from which data was collected were 18 and a qualitative research approach was used as a main research methodology. The responses obtained were subjected to content analyses. The main findings of the study include; informal traders are uncoordinated, informal traders are faced with challenges which hinder their success, majority of respondents see benefits from informal trading, the informal sector of responds to triple social ills and all respondents started up businesses due to the inability of the formal sector to create job opportunities that are permanent and enough for everyone. In response to the findings about the main recommendation made is the improvement of communication between government and informal trader for the sustainability of municipal programs.

- Description: This study explored the attitudes of community members on the professional behaviour displayed by nurses towards their clients in Dutywa location of Mnquma local Municipality, Eastern Cape. The study endeavoured to achieve the following specific objectives: (i) to explore the community members’ perceptions towards the professional behaviour displayed by nurses towards their clients; (ii) to establish the community members’ perceptions on the impact of nurses’ professional behaviour towards the healing of patients; and lastly (iii) to establish strategies to enhance the nurses’ positive professional behaviour towards their clients. The study was premised on Socio-Ecological Model. Methodologically, the study used both qualitative and quantitative paradigm and was thus guided by mixed research designs, which were a case study and a mini survey. The data was collected through in-depth interviews, and focus group discussions in the qualitative aspect of the study. In addition, the quantitative data was gathered through the use of questionnaires. The study used both nonprobability and probability methods of sample selection. Specifically, purposive sampling for qualitative sample and cluster random sampling for quantitative sample was used. Using these techniques, ten (10) participants were selected for qualitative individual interviews, and two focus groups which comprised of five (5) members for each group. Furthermore, questionnaires were (30) individual respondents. Qualitative data was analysed using content thematic analysis, while descriptive statistics was used to analyse quantitative data. The study revealed the following: maltreatment of patients by the nurses; nurses’ behaviour revealed professional deficit; nurses manifested bias in treating their patients; the phenomenon of patients being arrogant and impulsive, negative v treatment dissuades patients from visiting the health-care services and a need for more training or holding workshops for in patient-nurse relationship. Based on the evidence gathered in this study, the following recommendations were made: nurses should revisit their nurses’ code of conduct; improving communication between both the nurses and the clients; and lastly increasing of staff members in the clinic. The study concluded that patient abuse has a long-standing history that can be traced back to ancient times, which is mostly common against women and children, in most cases; the client is often vulnerable because the nurse has more power than the client. Moreover, the nurse has influence, access to information, and specialized knowledge and skills, of which that alone can lead to the nurses mistreating their patients.

Moreover, the nurse has influence, access to information, and specialized knowledge and skills, of which that alone can lead to the nurses mistreating their patients.

- Description: The quality of teacher education seems to have become a crucial point of debate worldwide. However, teaching seems to be one of the careers without a recognised apprenticeship. Therefore, mentoring has been seen as an appropriate way for experienced teachers to guide, assist, coach and motivate teachers in their teaching capacity. Teaching capacity is described as having a broad content which can be related to quality teaching, teacher effectiveness and teacher behaviour in the classroom or in the school. The lens with which the study was viewed was through Lave and Wenger’s (1998) theory, Community of Practice (CoP). Community of Practice is defined as a process of social learning that occurs when people who have a common interest in a subject or area collaborate over an extended period of time, sharing ideas and strategies, determining solutions and building innovations. The study used mixed methods and concurrent triangulation design in sampling 60 participants for quantitative data and 6 participants for qualitative data. The unit of analysis were novice teachers who were randomly and purposively selected. Data gathering methods included questionnaires, classroom observations and document analysis. The focus was on the primary schools, Foundation Phase (FP) novice teachers. The findings revealed utilisation of different mentoring approaches such as one on one; Foundation Phase Team and school- based mentoring. Although the study reveals that the work of the mentor teachers and novice teachers has evolved to include Learning Teams to improve the teaching capacity of teachers; some mentoring approaches were less effective. The study suggests, therefore, that schoolbased and district-based mentoring programmes to be formally organised as part of developing novice teachers’ teaching capacity.

- Description: Since the end of the Apartheid Regime, various labour legislation has been enacted over the years to eliminate discrimination and grant everyone in South Africa the right to fair labour practices, including the prohibition of unfair payment practices in terms of item 2(1)(a) of Schedule 7 of the Labour Relations Act.1 The above item was repealed and replaced with an express provision strictly prohibiting unfair discrimination in any employment practice or policy.2 However, even though this express provision strictly prohibited unfair discrimination in employment, the International Labour Organisation criticised South Africa for the failure to include an express provision dealing specifically with equal remuneration in terms of the Employment Equity Act.3 Because of this criticism, sections 6(4) and (5)4 were introduced. Section 6(4) amendments were obviously not been successful as intended, as numerous employees still are facing unfair discrimination based on the wages. Looking at Case law in the United Kingdom, there are clearly principles and successes that South Africa can learn from and incorporate in South African labour law. Some successes include the proactivity of employers who identify groups of employees, which are performing work that is of equal value, comparing their salaries, and by investigating and removing pay gap causes. Another success is the use of reports of independent experts who can assess the value of different occupations. If South Africa does this, it will alleviate the pressure placed upon courts that do not have the necessary expertise to decide on the value.

- Description: The subject of this treatise was the construct “Creating Shared Value”. The purpose was to explore the business models companies use to create shared value. The study was based on the life insurance industry. The study employed a qualitative paradigm and four Cases were content analysed. It was found that business models used by the insurance industry increase quality of life and thereby increasing social value; further these business models increases economic value for business through the reduction of insurance costs . This mutual and simultaneous creation of economic value and social value is the underlying principle of the Shared Value Construct. Secondly it was found that business models used by the life insurance companies selected for the study manifested hybrid business models with features of both inclusive and social business models components. Practical implications – Policy makers should consider providing universal coverage based on the emerging hybrid business model as an alternative to National Health Insurance business model that is aimed at compulsory membership of citizens to a medical aids. These model enhance early detection of disease’s which promotes better health management and prevention, literature review correlated this with better productivity, less insurance claims and general wellbeing of the citizens.
