  • Description: South African Black visual artists have to contend with the racialized economic disparities of the country within which they are enmeshed. This make them susceptible to producing work with the sole motivation of not slipping (further) into poverty, which can greatly hinder our creative autonomy. We are further constrained by the fact that visual arts institutions, whose role it is to decide and regulate what constitutes legitimate art, still operate in accordance with whiteness and a white supremacist logic. The combination of these two factors can lead to the interpellation and artistic production of a Black subjectivity that predominantly caters to – and understands itself in relation to - whiteness. This process of subjectivation, which is performative, can - and regularly does - materialize in various ways through our studio practice. However, with the intervention of critical theory (and the application of strategies of resistance to hegemony that it can provide), interrogative self-reflexivity, and a singular perspective, it is possible to create work that disrupts and transgresses these norms, ultimately contesting the prevalent notion of Black identity as a homogenous experience.

  • Description: There are many contextual challenges related to this problem. Some of these include the mass of diverse students entering tertiary institutions and the level of educational preparedness of these students. Moreover, the lasting legacy of Apartheid brings its own challenges in relation to widening access for students entering South African higher education institutions. There are considerable repercussions related to the costs of re-educating students and re-admitting failing students into continuously growing classes. Furthermore, there is a protruding argument that the level of student readiness/preparedness is continually declining. The above-mentioned challenges place extreme pressure on higher education institutions and their staff to provide academic support to students, along with maintaining adequate pass rates. Reflecting on the challenges faced in the South African higher educational context, it is evident that the development and implementation of academic support programmes are important. These programmes are aimed at providing quality learning and teaching and counteracting declining success rates. In addition, there is a need to transform how massification of higher education takes place, to address the challenges of diverse student profiles, dropout rates and low throughput rates. This study explored the impact of academic support interventions on academic performance by focusing on student engagement as it is the leading factor of academic success. For the purpose of this study, this was measured through the attendance of academic interventions. Student engagement may be defined as the time and energy learners dedicate to educational activities both inside and outside of the classroom, along with the policies and practices institutions use to persuade students to partake in these activities. The findings revealed that academic interventions indeed have a positive influence on student behaviour and student academic progress. The results of this study could assist the department of HRM in determining the effectiveness of academic interventions created for first year students.

  • Description: Carnivores are declining and undergoing substantial range contractions which have largely been attributed to anthropogenic related. Globally, there has been an increase in establishing protected areas for species conservation. However, protected areas may not always effectively conserve all biodiversity, where some areas are too small for viable populations of wide-ranging species, such as leopards Panthera pardus, spotted hyaenas Crocuta crocuta, and brown hyaenas Parahyaena brunnea. The importance of privately-owned areas are gaining increasing recognition for their role in conserving species, and ecosystems. Though such areas may provide key opportunities for the conservation and persistence of biodiversity, little attention (with regards to species conservation planning) is given to these areas. Furthermore, large carnivore populations increasingly have to share the landscapes with humans as the global human population increase. Though anthropogenic impacts can be limited within protected areas, human activities on privately-owned farmlands are mostly dictated by economic activity to sustain human presence (often leading to humancarnivore conflicts). Platjan (South Africa) is one such area. It comprise a matrix of agricultural practices and land-use types, dominated by humans. Consequently, it presented an ideal landscape to investigate how humans and carnivores coexist. Spatial capture-recapture modelling suggest stable populations manifested through low densities for leopards, spotted hyaenas, brown hyaenas, and Africa civet Civettictis civetta within the study area. Densities of the focal species were more similar to what has been found in more arid environments. Though it should be noted, that population fluctuations are common in nature, and this study only provide a brief snapshot of the population. Nonetheless, it provides baseline carnivore density estimates for the area. Single-season, single-species occupancy modelling was used to determine the influence of anthropogenic variables on species probability of site use. Results suggested that leopards and spotted hyaenas avoided crop fields (possibly due to higher human activity in these areas). Whereas black-backed jackal Canis mesomelas were positively influenced by the proportion of survey sites containing human infrastructure (possibly due to additional food sources provided by human presence). The covariates did not suggest any effect on brown hyaena and African civet probability of site use, which may be explained by temporal niche partitioning between the species and humans. Kernel density estimation and selectivity ratios revealed that all carnivores were predominantly crepuscular-nocturnal, with the exception of brown hyaenas which were strictly nocturnal. Among the focal species, brown hyaenas and African civets had the lowest temporal overlap with humans, which may explain why they weren’t affected by any of the anthropogenic variables. Whereas, jackal had the highest overlap, supporting a notion that they may be more tolerant of human presence than the other study animals. Overall, it seems that carnivores are able to coexist with humans on privately-owned farmlands through temporal niche partitioning, but manifest at rather low densities. Nonetheless, this study adds to the current understanding of human-carnivore coadaptation, and provides the first carnivore density estimates for the Platjan region.

  • Description: Many of today’s news headlines are fraught with alarming accounts of fraud and Corruption conducted by business leaders and this study was undertaken to investigate the influence of perceived ethical leadership on employee engagement. The question has arisen whether these unethical actions among business leaders impact the perceptions of employees and whether this affects their engagement with the organisation. There has been an increase in studies on employee engagement, due to the significant positive impact that it has on an organisation and the beneficial outcomes that engaged employees produce. In this study, the research design followed a positivist approach. The research participants consisted of middle managers in the public or private sectors in South Africa. Sampling was done using a non-probability convenience sampling technique. Secondary data was collected using research data from the Nelson Mandela University Library and its online database. Primary research data was collected using self-administered, standardised questionnaires making use of a 5-point Likert scale. Data was interpreted by means of inferential statistics and biographical information. Every precaution was taken to ensure the reliability, validity and trustworthiness of the study. Ethical approval was obtained for the study from the Nelson Mandela University Research Ethics Committee as per the protocols that were in place at the time of the data collection. This study is significant in terms of the upsurge in unethical conduct in the business arena. The primary objective of this research was to determine the influence of perceived ethical leadership (Perceived Leader Integrity) on employee engagement (the factors which constitute engagement are job commitment, job satisfaction and future intentions.). In the findings, a moderate relationship was found between PLI and job commitment and job satisfaction. A negative relationship was established between PLI and future intentions. Therefore, ethical leadership had an influence on employee engagement.

  • Description: The construction industry is characterised by the high rate of project failures. Industry professionals consider inconsistent project management practices to be a major cause of these failures. A leading contributor to these inconsistent project management practices is that there is no one project management standard followed in the industry, thereby resulting in different interpretations and applications by project managers. Given the intricate nature of construction projects, correct project management practices and project management maturity are paramount in achieving the overall envisaged project benefits,project success and business profit by organisations. As such, this study arose from the desire to improve the prevailing practices in construction projects, particularly in the Private Healthcare Industry. Against this background, the purpose of this study was to develop a framework that aims to improve the prevailing project management practices in infrastructure projects within the Private Healthcare Industry. This was done through evaluating the appropriate frameworks and theories in construction project management practices, project management maturity, and project success concepts. This then led to determining the correct construction project management practices required for the successful execution of infrastructure projects. To achieve this goal, a comprehensive review of literature was conducted that covered a review of project management practices, benefits, and theories The review of literature concluded with the main study proposition: Project management maturity has an influence on project success.

  • Description: Worldwide, states that had incorporated international standards of arbitration or drew influence from them, thrived in providing effective and efficient resolution of international commercial disputes. However, since 1965, there had been little to no increase in resolving international commercial disputes between private parties in South Africa, either through the court or arbitration. As a result, private parties were drawn to arbitrating in states that had incorporated these international standards and conformed to the aim of unifying arbitral regulation. This study aims to determine what South Africa’s response was in dealing with international commercial disputes and the development of arbitration as an appropriate dispute resolution mechanism. Based on the premise that arbitration is regarded as a popular dispute resolution mechanism when it comes to international trade transactions globally, this study will unpack why arbitration in South Africa did not reflect this premise. A thorough analysis of how international arbitration and its regulation developed globally will be conducted to show at what point uniform regulation came about. The results will indicate in what ways South Africa’s regulatory framework was insufficient to deal with international arbitration and will show how it took a considerable amount of time to regulate arbitration appropriately. Upon regulating international arbitration in 2017, the study will show other ways that South Africa can enhance itself in terms of providing a comprehensive regulatory framework and position itself as an ideal seat of arbitration in Africa.

  • Description: Interactions between apex predators, mesopredators and their impacts on trophic dynamics have been well documented. However, the influence of apex predators, through the provision of carrion, on the foraging ecology of African mesopredators is poorly understood. To investigate such resource supplementation by apex predators for mesopredators, the black-backed jackal Canis mesomelas, a generalist mesopredator, was used as a model species to improve our understanding of this topic in South African ecosystems. To do this, I compared the diet of jackal at replicated sites with and without cheetah in the eastern Karoo, South Africa. Scat samples were macroscopically categorized into six broad dietary categories: mammal, reptile, bird, fruit, forage and insect. Mammalian prey was further identified to species and grouped into six functional dietary categories: carnivore, large ungulate, small ungulate, small mammal, and unknown mammal. Jackal diets were dominated by mammal prey, with significant differences in the biomass and frequency of occurrence of mammals by jackal at sites with cheetah and without cheetah. Mammal consumption, showed limited variation amongst seasons. Resource supplementation provided by predator derived carrion is an important factor influencing jackal foraging ecology. The emergent hypothesis that jackal may show demographic responses (increased fecundity, survival, density) to this supplementation needs to be tested. This study also provided an opportunity to investigate the potential role of jackal as an endozoochore. Jackal consume fruits and their seeds, yet to our knowledge, an investigation into their seed dispersing abilities is yet to be investigated. This study assessed the viability and germination capacity of ingested seeds extracted from jackal scat samples using the tetrazolium tests and germination trials. Seed viability and germination of all three species (Grewia occidentalis, Pappea capensis and Diospyros lycioides) were significantly lower than uningested seeds. These results suggest that jackal gut passage is acting severely on ingested seeds. This study represents a novel investigation into differences in jackal diet in sites with and without cheetah as well as the role jackal play in endozoochory, contributing to improved understanding of the ecological role of jackal.

  • Description: This study seeks to determine the legality and enforceability of an automatic termination clause in a contract of employment. Our law seems to have two different procedures in dealing with this issue. The first aspect is to determine whether the automatic termination clause is inserted in a contract of employment merely to circumvent the provisions of the Labour Relations Act (LRA), in particular section 5(2)(b) of the LRA. If the intention is found to be to circumvent the purpose of the said provisions of the Act, then an automatic termination clause is not allowed and any termination of the contract resulting therefrom becomes a dismissal challengeable at the CCMA, Bargaining Council or Labour Court depending on the issue at hand. In the alternative, there is no dismissal for the purposes of section 186(1) of the Act in circumstances where the end of an agreed fixed term is defined by the occurrence of a particular event. Put differently, there is no dismissal when the agreed and anticipated event materialises. The Constitution of the Republic of South Africa provides that everyone has the right to fair labour practices. This provision guarantees the right not to be unfairly dismissed and is in line with Article 4 of Convention 158 of the International Labour Organisation which provides that the employment of a worker shall not be terminated unless there is a valid reason for such termination connected with the capacity or conduct of the worker or based on operational requirements of the undertaking, establishment or service. This study aims to investigate the question of the legality and enforceability of an automatic termination clause in a contract of employment by analysing inter alia, the Constitution, LRA, ILO recommendations and the authorities in order to determine the extent of protection afforded to employees against employers.

  • Description: The right to access health care services is enshrined in section 27 of the Constitution. It is a right afforded to everyone. The state is required to adopt legislative and other measures for the progressive realisation of this right. To that effect, the state has passed various pieces of legislation aimed at realising the right to access health care services. The key legislative measures regulating the health system are the National Health Act, the Medical Schemes Act and the Medicines Act. Despite the various legislative measures in place, not everyone has access to health care services and there is a need for reform in the health system. To remedy the problem of inaccessibility, the government introduced the NHI Bill in 2018 which was amended in 2019. The NHI Bill purports to amend the way in which health services are financed. The purpose of this research is to determine the constitutionality of selected aspects of the NHI Bill. Section 27(2) of the Constitution requires that any measure adopted by the state in realising the right to access health care services must be reasonable. This research, therefore, assesses whether the NHI Bill is a reasonable measure that meets the requirements of section 27(2). The NHI Bill will be assessed in light of the reasonableness review used to assess state compliance with the obligation in terms of section 27. In assessing the reasonableness of the NHI Bill, reference is made to the domestic obligations of the state to realise the right to access health care services, the context in which the NHI Bill was published, the provisions of international law, and the impact the NHI Bill will have on other rights specifically the right to equality. The findings of this research are that the NHI Bill is likely to be found unconstitutional insofar as it unfairly discriminates against asylum seekers and undocumented migrants and lacks clarity with respect to important issues such as the role of medical schemes. Based on this analysis, recommendations are made to ensure that the NHI Bill is constitutionally sound.

  • Description: Social housing aims to redress the housing crisis that South Africa is currently facing given the backlog that was left in the provision of free basic housing. Research conducted on the low to the middle-income group from which South African social housing tenants originate, suggests that this income bracket experiences social, physical and mental health challenges. They are three times more likely to suffer from depression than their counterparts in developed countries. Little to no literature has been published focusing on tenants who represent low to middle-income groups living in social housing in South Africa. Furthermore, the researcher did not come across literature highlighting the perceptions and experiences of tenants, who represent these low to middle-income groups, and who live in social housing in South Africa. In the context of South African social housing, there is a gap in the literature about the perceptions and experiences of tenants living in a social housing initiative.Guided by the Social Constructionism and Sense of Community theoretical frameworks, the goal of this qualitative research study waste gain a better understanding about the perceptions and experiences of tenants living in a social housing initiative in South Africa. An exploratory and descriptive research design was employed, focusing on the tenants of one social housing initiative. A non-probability purposive sampling procedure was followed. Convenience sampling was applied and followed up by volunteer sampling techniques. The sample size consisted of 9 social housing tenants. Individual, semi-structured interviews were conducted by an independent interviewer and used to collect data and analyse themes. Trustworthiness and ethical considerations were adhered to on all levels.This research contributes to a greater understanding of the perceptions and experiences of tenants living in a social housing initiative. The study revealed that most tenants experienced an increased sense of safety in the social housing initiative as compared to the surrounding community. The study further revealed that lower-income tenants have concerns about the long-term affordability of rentals in social housing. Among others, the study recommends that social workers advocate for inclusive social and economic policies to promote greater inclusion of vulnerable groups from low-income backgrounds.

  • Description: The possible application of the FT Raman, Raman micro-spectroscopy and ATR-FTIR micro-spectroscopy, have been investigated for distinguishing between wool and mohair. Highly identical Raman and FTIR spectra were obtained from the two fibre types, indicating that indeed they share similar basic molecular structural chemistry. The analysis of the amide I through curve fitting of wool and mohair FT Raman spectra showed that the protein and polypeptide secondary structure exists mainly in the α-helical structural conformation with smaller proportions of β-pleated sheet and β-Turns. These proportions, however, could not be used to distinguish between wool and mohair, due to the significant overlap observed between the two fibres. This study also determined the disulphide contents for possibly distinguishing between wool and mohair fibres, with the average and standard deviation values of 0.20±0.04 and 0.17±0.03 for wool and mohair, respectively, being found. Despite the mean values being found to differ statistically significant (p<0.05), a considerable overlap was observed, posing a doubt in the possible application of the method for distinguishing between the two fibres and blend composition analysis of the two fibres. The application of ratiometric analysis, based on the relative peak heights of certain FT Raman bands, showed that a combination of ratios A (I2932/I1450) and D (I508/I1450) could hold great potential in distinguishing between wool and mohair fibre samples. The individual values of ratios A and D varied a great deal from one mohair sample to the other and even more from one wool sample to another, with the individual values for ratio A ranging from 2.71-3.68 and 2.35-3.08 for wool and mohair, respectively, while ratio D ranged from 0.18-0.32 and 0.17-0.22 for wool and mohair, respectively. An important observation from this study is that if, for an unknown sample, if individual values of ratios A and D exceed 3.1 and 0.22, respectively, are found then the sample is most likely to be either a pure wool or blend of wool and mohair, whereas if all the values fall below the two threshold values, then the unknown sample can be declared a pure mohair sample. A Raman spectral database or library of approximately 100 high quality Raman average spectra of wool and mohair fibres has been established for the Bruker 80V FTIR/Raman spectrophotometer at the Nelson Mandela University (NMU). Although this has not been fully validated due to the unforeseen frequent breakdown encountered with the FT Raman system, at this stage, it has been realized that verification of unknown materials is highly possible. A great need for the development of a classification model based on multivariate or chemometrics has been realized. An ATR-FTIR LUMOS micro-spectroscopic system was also investigated for the possible application in distinguishing between wool and mohair single fibres. The amide I/II band ratios were determined for both wool and mohair fibres to distinguish between the two fibre types. The mean and standard deviation values of 1.20±0.02 and 1.21±0.01 for mohair and wool, respectively, were found and were shown not to differ statistically significant (p˃0.05). The secondary structure analysis showed that the content of the α-helical secondary structure might be different between the two fibre types, with a great overlap of individual values, however, being observed between the two fibre types (wool and mohair), raising concerns in the possible application of the α-helical content for distinguishing the two fibres.

  • Description: The South African hunting industry, but more specifically local hunting, is regarded as one of the key sectors within South Africa’s wildlife industry – not only for the significant economic contribution it makes, but also from an equally vital conservation point of view. Despite this, local hunters are neglected in the sense that hunting accommodation and hunting packages provided by the majority of game ranches mainly focus on accommodating trophy hunters. This study investigated the profile of local hunters in South Africa. The objectives of this study were the following: establishing the factors which determine the profile of local hunters and then comparing the results to existing information, as well as identifying the economic contribution local hunters make towards South Africa’s economy. The study commenced with a literature review of existing research on the local hunting industry and on the profile of local hunters. Thereafter, a self-administered questionnaire was developed and conducted amongst active local hunters via the CHASA hunting confederation website, by means of which the primary data for the current study were collected. The study concluded that the profile of the South African local hunter has undergone slight changes from what previous research had established. This was attributed to several external as well as internal factors. The current research would assist hunting farms in approaching the local hunting sector with up-to-date information in order to accurately tailor their packages and marketing in line with the evidence presented in this dissertation regarding the changes in the profile of the South African local hunter.

  • Description: The goal of this study was to carry out a comprehensive assessment of the quality of healthcare in the Port Elizabeth Hospital Complex in the province of the Eastern Cape in South Africa. The assessment was made on the basis of the perceptions of patients of the features of the hospital and the services which it provides to patients. A quantitative research design was adopted to conduct the study. The data was derived from a questionnaire which the research assistants administered to patients in a number of surgical clinics in the hospital. Across-sectional sample of 350 patients, who were making their first follow-up visits after having previously been admitted to the hospital to undergo surgical procedures, was obtained by making use of convenience sampling. The researcher made use of the modified SERVQUAL scale for hospital services in order to measure the extent to which the participants agreed with statements pertaining to five specific dimensions of the quality of service, namely, tangibles, reliability, responsiveness, assurance, and empathy. The overall gap score was negative (-0.52), which indicates that the respondents perceived that the quality of healthcare which the hospital provided was unsatisfactory. Although the gap scores for each of five of the dimensions of quality were negative, the two dimensions whose gap scores reflected the highest levels of dissatisfaction were reliability (-0.66) and responsiveness (-0.63). The findings of this study could assist the Department of Health of the Eastern Cape Provincial Government to appreciate the perceptions of the public of the quality of healthcare which the Port Elizabeth Hospital Complex provides to patients. The recommendations which are made on the basis of the findings of this study could assist policymakers and members of the senior management of the hospital complex to formulate policies which result in substantial improvements in the quality of healthcare in the hospital complex. Further research is still needed to identify the factors which adversely affect the performance of the staff of the hospital and limit their ability to provide satisfactory healthcare consistently to patients.

  • Description: Employee wellness and work engagement have a positive influence on organisational behaviour. The main aim of the research study was to understand whether a relationship existed between employee wellness and work engagement in a Non-Governmental organisation (NGO). The research used a cross-sectional design and a composite questionnaire to measure employee wellness and work engagement. This was a paper and pen-based questionnaire which was distributed to 160 employees. Of the 160 questionnaires distributed only 155 participants responded. These participants are employed at NGO’s based in Port Elizabeth, Johannesburg and East London. An exploratory factor analysis determined a new more reliable factor structure for PWS. Employee wellness lost items and became a three-factor structure. The results showed that the new EFA model was best suited for the present study. Work Engagement remained a three-factor structure. T-tests and ANOVAs revealed significant differences between the constructs and the demographic groups. Correlations showed the main findings of the study to be a relationship between employee wellness and work engagement in a non-governmental organisation.

  • Description: Elephants were successfully reintroduced into the 900 km2 fenced Hluhluwe-iMfolozi Park (HiP) from 1981 onwards and their population has increased exponentially since. Their initial reintroduction was motivated by the need to control bush encroachment and to maintain ecosystems such as grassland and open woodland, and to restore ecological processes offered by elephants. The subject of the HiP elephant population and their impact on vegetation in the Park has become controversial; with some concerns being raised that the population is too high and is negatively affecting the vegetation. An absence of a vegetation monitoring programme in protected areas with elephants creates uncertainty leading to an ‗elephant impact‘ debate. This study aimed to compare the perceptions of stakeholders regarding the issue of elephant impact in HiP with measured elephant impact on the vegetation in the Park. The perceptions and concerns of stakeholders regarding the effects of elephants on vegetation in HiP were investigated using a questionnaire. Stakeholders reported that elephants and fire were the main factors shaping vegetation change in HiP over the past decade. Sclerocarya birrea, Senegalia burkei and Schotia brachypetala were reported as the most negatively affected species. Also reported that they are concerned about the effects of elephants on the number of tall trees in the park, tree mortality and elephant‘s effect on rare indigenous vegetation. Most interestingly, the results showed that the groups of stakeholders had different perceptions of the level of elephant impact on the vegetation in the park; except for researchers and tourists whose were not significantly different from each other. Managers had the most respondents that reported that the level of elephant impact is unacceptable, while most researchers and tourists reported that the level of elephant impact is at an acceptable level. Vegetation plots that had been surveyed in 1999, 2003 and 2007, were resurveyed in this study during 2017 to assess elephant impact on vegetation over time. Comparison between the years sampled showed that there was a decrease in the density of tall trees, while the density of trees in 0.5-2 and 2-4 m height classes increased over the same period. Elephants had a strong preference for utilizing tall trees (>4 m) and a strong avoidance for trees in the height range from 0.5-2m tall (Jacobs selection index 0.56 and -0.69, respectively). This trend was apparent for all sample periods. In addition, elephants also showed a strong preference for some rare species including S. brachypetala and Sideroxylon inerme. Between 1999 and 2017, the density of preferred species has decreased while the density of avoided species has increased. I conclude that elephants are having a noticeable impact on the vegetation at HiP by changing vegetation structure to a shrub dominated vegetation, and causing a shift in species composition towards avoided species. The findings of this study show that the perceptions of stakeholders on the effects of elephants and the level of elephant impact on vegetation match the results from measured elephant impact - vegetation survey. However, Thresholds of Potential Concern (TPCs) should be outlined in the elephant management plan and are required to determine whether the levels of elephant impact at HiP have exceeded an acceptable level or not. This study conforms to previous research that an uncontrolled elephant population can have substantial impacts in fenced reserves. This study shows the importance for long-term and continuous vegetation monitoring programme to obtain reliable data to determine trends in vegetation changes over time.
