  • Description: The resettlement of immigrant and refugee populations poses specific challenges to new host communities. Municipalities must find resources to assist these populations in transitioning into a new culture. Immediate needs are often adequate housing, health care, and primary schooling. While this transitioning process is still in play, the search for employment begins; often at the cost of consideration of longer-term needs, such as English or other host country language acquisition and planning for long-term career goals. Theorists in the field of social capital postulate that bonding and bridging social capital offers benefits for populations adjusting to new communities. Connections to like-minded individuals or pre-existing ethnic ties (bonding social capital) can provide support important to the well-being of individuals going through difficult social adjustments while connecting with new social groups (bridging social capital) can provide new information leading to expanding opportunities. The concept of bridging social capital for immigrant and refugee populations is the subject of this research study. It is situated within the context of our digital age in which information communication technology (ICT) is the primary mode of access to information and services. For the purpose of this thesis, the capability to exploit this mode of communication is thus identified as “digital capital.” As more and more governmental, educational, and social services are distributed within a technological environment, it is necessary to examine this mode of connection to information as a form of capital which can be viewed in a similar framework to other types of social capital. Access to technology and ICTs has been considered an integral element of the Development Goals as adopted by the United Nations for the Year 2000 Millennium Goals. Though later debates have questioned how ICTs may have benefited development goals, the pervasiveness of this form of information flow continues. Within Development Studies, Sen’s theory on the Capability Approach offers a valuable opportunity of connecting digital capital to development. Just as the Capabilities Approach accommodates the diversity of human values, characteristics, and functionings, so can digital capital provide flexibility through adaptation by the users to tailor the medium to meet specific needs. It is this freedom to adjust to individual needs and goals that allows this mode of bridging capital to hold a distinct advantage for immigrants and refugees who are searching for effective links into new social networks in the job search process. The role of the community college system has been at the forefront of providing educational training and social acclimation for this population in their quest for economic self-sufficiency in the resettlement process. A greater understanding of the role that technology plays in the success of immigrant and refugee resettlement is vitally important for the well-being of communities undergoing dynamic demographic change.

  • Description: Since Sudan’s Comprehensive Peace Agreement (CPA) was signed in 2005, its border with Uganda has become a hub of activities. These economic activities have been enhanced by ethnic and political relations, but also by diplomatic relations between the two countries. Contrasting developments on the Ugandan side of the border with those on the South Sudanese side, this research draws on empirical fieldwork to examine the impact of diplomatic relations on the development between both countries since 2005, with international trade as the main aspect of development. The study sets out to show how trade between both countries has been affected by the diplomatic relations between them. The post-CPA demand for goods and state-building processes created a range of economic opportunities for traders. This was particularly the case for Ugandan large-scale traders who, as a result, became an important and empowered group. These factors have further been enhanced by good diplomatic relations between both countries, and as a result South Sudan has become Uganda’s most important trading partner as well as a destination for many Ugandans to conduct their trade. Simultaneously, post-conflict problems have emerged in South Sudan such as insecurity, weak government institutions run by incompetent officials, corruption, high foreign exchange rate, cultural diversity, mistrust and poor infrastructure. These problems have emerged as major challenges to trade and investment by Ugandan traders in South Sudan with traders as well as government officials agreeing that these challenges present major setbacks to trade and investment in South Sudan. Ugandan small-scale traders in particular have become more vulnerable to expressions of authority on the part of South Sudan’s post-CPA state, in which state or individual military might is used effectively to control trade. The current conflict, which began in December 2013, has added a new dimension to the list of impediments to trade as insecurity and economic instability have precipitated an atmosphere of uncertainty among many traders and investors. Despite all those challenges, Ugandan traders as well as government officials still view South Sudan as a business destination of choice. Overall, the study confirms that diplomatic relations have enhanced international trade between South Sudan and Uganda by way of solving trade disputes, investment promotion and influencing leadership on policy matters.

  • Description: This work has explored novel concepts of crab vulnerability, recovery and resilience under unprecedented climatic changes in South Africa’s first UNESCO World Heritage Site. By showing how large salinity shifts and prolonged interruption of the marine connection can drastically affect brachyuran diversity and community structure in St. Lucia Lake, the potential cascading effects on ecosystem functioning were estimated. Only 15 crab species were recorded within the system during this study, compared to the 26 species that were known to occur prior to the recent environmental shift (i.e. 58% decline). The impact of this biodiversity collapse has negatively affected the associated mangrove ecosystem in particular, with the entire community of fiddler crabs persisting only in a small area near the estuary mouth. Gut fluorescence measurements have shown that, due to a lack of tidal Influence, their grazing impact on microphytobenthic biomass may become unsustainable. However, although adults are able to survive in this environment, the larvae require a marine connection; and they are thus unable to tolerate the wide fluctuations in salinity currently prevailing in the system. The study concludes that brachyurans are key factors to consider during conservation planning, as they are crucial to maintaining ecosystem function in the face of environmental change. This research is of global relevance, as many similar estuarine and coastal lakes around the world are currently experiencing similar state shifts. All six chapters included in the thesis have already been published in the peer-reviewed literature; and the project results have also earned Nasreen the NRF award of Next-Generation Researcher of the Year for 2015.

  • Description: Market demand for the fynbos-derived honeybush (Cyclopia spp.) tea is on the rise, and there is an urgent need for better conservation of wild Cyclopia populations and for a shift to sustainable cultivation. Rooibos is another popular fynbos product that underwent exponential market growth over the last two decades but this resulted in large-scale conversion of pristine mountain fynbos to intensively-used crop lands. Adopting a conservation agriculture approach in expanding indigenous products will help in conserving biodiversity and ecosystem processes in this global biodiversity hotspot. Conservation agriculture of indigenous fynbos products grown in the Cape Floristic Region (CFR) should follow five main principles in order to maximise biodiversity conservation alongside agriculture. These principles are: 1) maintain high diversity at all levels, 2) conserve soil structure and processes, 3) conserve and restore natural ecosystem processes, 4) promote ecosystem stability and self-perpetuation, and 5) maintain natural areas as sources of ecosystem components. Given the negative ecological consequences of the industrialisation of the rooibos industry, it would be in the interest of biodiversity conservation, and even of agriculture, to apply these principles to honeybush cultivation. In order to prevent further fynbos habitat loss, cultivation of honeybush could be catalysed on old fields rather than in ploughed or cleared fynbos. Here I compare germination, growth and survival of two species (Cyclopia intermedia E.Mey. and C. subternata Vogel) between different land use types (ploughed lands, old fields and intact fynbos) and treatments (cleared and uncleared) in the Langkloof, Eastern Cape, over one year. Plots of each land use type were subject to each of these two treatments, although the ploughed plot constituted only a cleared treatment. Growth was highest on ploughed land, while survival and growth were lowest in uncleared fynbos. Cleared fynbos had the lowest germination success in both species, with the other sites and treatments coming out roughly the same. These results show that although ploughed lands give highest yields, growth and survival on old fields without ploughing is comparable with that on ploughed lands and is therefore a feasible alternative. Understanding the recruitment dynamics of honeybush is imperative for adequate conservation of wild populations. Furthermore, understanding this ecological aspect of the genus will help in developing the honeybush industry as a sustainable, agroecological market that uses semi-natural populations for production. Although Cyclopia species are early-successional species that germinate after fire, recruitment of Cyclopia pubescens Eckl. & Zeyh. continues throughout the inter-fire period. Cyclopia pubescens populations near Port Elizabeth were described according to their age structure and plant densities to discern possible density-dependent recruitment effects. Results showed that dense stands for the most part do not support high post-fire recruitment. This gives insight into suitable planting densities for new or restore populations and into management guidelines for remnant populations of threatened species. This thesis highlights important issues facing the honeybush industry. Mainstreaming biodiversity conservation into honeybush production is achievable, given that the industry is still relatively young, but this will require further research and strong market leadership.

  • Description: Graduate unemployment, more specifically the continued inability of young people to make a successful transition from institutions of higher learning to labour markets, remains a key concern and one of the most pressing socio-economic issues facing South Africa. Of similar concern, has been the inordinate length of time it takes for graduates (particularly black graduates) to acquire employment. This research study was undertaken in an attempt to understand employment trends among black graduates: its specific aim is to determine, the length of time it takes for black graduates to acquire employment after graduation. As a secondary aim the study also seeks to determine the underlying causes of long-lasting unemployment. The study investigated the employment circumstances involving a sample of 40 graduate participants from Motherwell Township: it was discovered that it took from 1-3 years for the respondents to acquire employment. The study also found that relative to their male counterparts it took much longer for female graduate participants to acquire employment. It also emerged that the type of qualification possessed by the graduates was a determining factor in the likelihood of their gaining employment timeously.

Effects of lethal management on black-backed jackal population structure and source-sink dynamics

  • Description: Lethal carnivore management, aimed at reducing carnivore impacts, threatens the persistence of carnivores globally. The effects of killing carnivores will depend on their life histories and social structures. Smaller canids, like black-backed jackals (Canis mesomelas), are highly adaptable and display variable population-level responses to mortality sources, which may contribute to their success in fragmented landscapes. Jackals, the dominant predator of livestock in South Africa, are widely hunted to reduce this predation. This hunting is heterogeneous across the landscape, focussed on livestock and game farms, with nature reserves acting as refuges. The aim of this research was to investigate the ecology and population dynamics of jackals in response to heterogeneous anthropogenic mortality. I hypothesized that the spatial variation in hunting results in the formation of a source-sink population structure, which contributes to the persistence of jackals. I addressed this hypothesis by evaluating two criteria, essential for the formation of a source-sink system in larger mammals. Firstly, I confirm that hunting pressures result in the formation of distinct subpopulations with asymmetrical dispersal (i.e. compensatory immigration) from unhunted reserves to neighbouring hunted farms. Secondly, I show that jackal subpopulation display asynchronous demographics, with farm populations displaying a relatively younger age structure and an associated increase in reproductive output (i.e. compensatory reproduction). This confirms the formation of a hunting-induced source-sink system. additionally, I show that jackals have a catholic diet, which confers a level of adaptability to direct (anthropogenic mortality, prey provisioning) and indirect (alteration in prey base) habitat modifications. This dietary flexibility allows jackals to obtain the appropriate resources to achieve reproductive condition. The relatively better body condition of younger jackals in sink habitats allows for compensatory reproduction which contributes to the success of jackals on hunted farms. Based on my findings, I hypothesize that the compensatory life history responses of jackals to anthropogenic mortality may be ascribed to two interconnected mechanism. Dispersal is presumably driven by density-dependent interference competition, as dominant territorial pairs outcompete subordinates in high-density reserve areas, forcing them to disperse onto low-density farms (i.e. ideal despotic model). Additionally, farms likely represent attractive habitats, owing to a reduction in conspecifics and a concomitant increase in resource availability (including anthropogenic resource provisioning). Therefore, dispersing subordinates presumably select for farms which are perceived as good quality habitats, as the high risks of anthropogenic mortality cannot be perceived by dispersing individuals. This results in the formation of an attractive sink or ecological trap. These compensatory processes will continue to counter population management actions as long as recruitment from unmanaged areas persists. This hypothesis provides a conceptual framework for future research directions in understanding jackal persistence and management (i.e. specifically focussing on controlling dispersal) of jackal populations.

  • Description: Efficiency analysis in the public sector assesses the performance of municipal and government entities in their provision of services to the public. South Africa, in particular, has experienced a large degree of negative feedback with respect to the ability of the government and its municipal departments to provide basic services to citizens. This has led to a number of service delivery protests throughout the country. To remedy this, the ability of the municipality to provide basic services needs to be assessed in order for improvements to be made. A first step in this process would be to determine the efficiency with which municipalities are providing these services. This study focuses on a particular municipal service, namely electricity distribution. Primarily, the efficiency with which municipalities provide electricity to consumers is determined. This is achieved using the parametric cost frontier approach, which is appropriate since municipalities aim to reduce the costs incurred in distributing electricity. The municipalities are compared to a frontier (theoretical best practice) from which inferences on their performances can be made. Those municipalities whose performances are not optimal, deviate from the frontier. The deviations (errors) are then assumed to be caused by two factors, namely stochastic random noise and inefficiency. This composition accounts for effects for which municipalities cannot control (stochastic random noise) and those for which it can (inefficiency). The parametric nature of the cost frontier approach allows for distributional assumptions to be made on these factors. Stochastic random noise is always assumed to be normally distributed, while inefficiency is assumed to be one-sided and positively skewed.

  • Description: This treatise aims to demonstrate an understanding of the complexities involved in the design of a German Embassy in Pretoria, in terms of technicality and identity. Programmatic requirements will be considered, with an emphasis on creating the maximum level of security against any reasonable threat. The identity of the embassy will also be considered through the lens of a symbolic aesthetic that must be reconciled with the embassy’s physical and symbolic context. At a time of increasing cultural homogenisation and growing sameness within an ever more interconnected world, this treatise will explore the problem of creating a unique physical expression of German cultural and political identity. This aim exists in tension with the growing fluidity and porosity of cultural identity at the present moment, and the research herein therefore seeks to articulate a new vision of cultural identity that can coexist with globalisation without losing its own specificity. In essence, an attempt will be made to give a concrete expression to cultural identity and move beyond preconceptions of this idea.

  • Description: Global leadership crises and increasing executive leadership failures necessitate a new approach to executive leadership development. Globalisation results in new leadership challenges that affect people, the planet and peace across the world. Critical issues include increasing extremism and terrorism, displaced migrants fleeing to stable countries, earth warming and economic decline. The role of the individual executive leader cannot be isolated from human development challenges. Various executive leadership failures and examples of unethical leadership practises, both internationally and in South Africa, place the focus on ethical governance and emotionally matured leadership development. This study follows a nexus, based on a three-stranded cordial link between human development, emotional intelligence and executive leadership. The central themes of the United Nations Human Development’s (UNDP) reports of 1990 to 2009 as well as the Post-United Nations Human Development Report of 2015 form a framework for evaluating the relationship between human development and executive leadership. Although economic growth is central to human development, the development of people through building human capabilities and active participation to improve their lives, are the main goals of the UNDP-2015. The role of executive leadership, leadership derailment and required executive proficiencies and attributes are investigated by evaluating traditional leadership theories and approaches as a lens for investigating leadership development. The positive effect of globalisation is that it affords new approaches and opportunities for executive leadership development. Emotional intelligence-based leadership, including the role of neuro-leadership, is evaluated and an integrative approach that involves the new paradigm of leadership as a response to human development challenges and globalisation is presented. The new paradigm of integrative leadership approaches includes empirical-based authentic leadership, shared leadership and gender-based leadership. The integrative leadership models of Hatala and Passmore are selected as a framework to propose a theoretical emotional intelligence leadership model for this study. New opportunities to develop emotionally intelligent executive leaders include technology-based training, iLeadership and eLeadership in an environment without boundaries. Time constraints are identified as a key obstacle for leadership development. Various training and executive coaching strategies are evaluated and proposed to accelerate leadership development. The link between human development and executive leadership development is proposed by collective leadership approaches towards Corporate Social Responsibilities (CSR) above entrepreneurial acumen and stakeholder involvement. A positivist approach based on quantitative research using Structural Equation Modelling (SEM) is used. The primary research problem is formulated to investigate the multidimensional and complex nature of factors that influence the success of developing emotionally intelligent executive leaders in South Africa. A conceptual theoretical model comprising of factors that influence Human Development and the perceived success of Emotional Intelligence Training is developed. A total of ten independent variables that influence the two mentioned dependent variables are identified. The proposed model and envisaged hypotheses are empirically tested. The study consists of a 73-itemed questionnaire with 360 participants. The sourced data are statically analysed by means of the exploratory factor analysis (EFA) to assess the discriminate validity of the research instrument and to confirm underlying dimensions of the constructs. Cronbach-alpha coefficients are calculated for each of the identified factors by using SEM. The significance of the hypothesised relationships in the revised model is tested. The value of this study’s contribution to the body of knowledge lies within the findings, the proposed Integrative Emotional Intelligence Leadership Model and recommendations for future research. The proposed model identifies practical training approaches to accelerate executive leadership against a background of serious leadership failures in South Africa.

  • Description: There is an overwhelming body of literature that exist in the subject of employee engagement. More and more studies are still conducted in this phenomenon as it had proved to produce high returns for organisations when mastered.The universal definition of this concept has not been found, various scholars continue to provide different views on how it should be defined. These definitions however bear common themes such as energy, taking initiative, going an extra mile, being grossly involved in the task, organisational citizenship, involvement, satisfaction, connection and enthusiasm which are caused by a feeling of being taken care of by the employer. It is clear from these that there is a reciprocal relationship between employer and employee which is claimed to have a link to profits and staff retention; as a result employers are increasingly devising strategies to engage the employees in order to reap the said benefits. The purpose of this study is to facilitate employee engagement and staff retention a motor manufacturing company in the Eastern Cape. In order to archive that the study assessed the level of engagement of artisans by means of a questionnaire focusing on factors such as meaningful work, organisational culture, social relationships, rewards and recognition and career development as these are repeatedly identified in the literature as key drivers of employee engagement. An imperial study was done on these drivers as well as on the existing company engagement programs to identify the employee’s perception of their effectiveness. The result of the study proves that artisans of this company are engaged and that all the drivers above were confirmed to have influence employee engagement and staff retention. The study however the study found that there is a split on the effectiveness of the existing engagement programs in the company with only less than 50% saying they were effective. A strong relationship was found to exist between all the factors that were studied and employee engagement and staff retention.

  • Description: Happiness is essentially the degree to which you find and judge your existence as favourable, in addition to an enduring, psychological feeling of contentment. In the hedonic view, happiness is pleasant feelings and favourable judgements, while the contrasting eudaimonic view describes it as doing what is morally right, what is righteous, that will enhance growth and that is meaningful to an individual. Both these views contribute to the overall happiness of an individual. People that are pleased with their lives usually experience greater satisfaction in their jobs. This is in line with the literature as happiness is positively correlated with job satisfaction, which suggests that a happy employee will most likely result in one that is satisfied with his/her job. In addition, happiness is correlated with evidence of success in the workplace and can increase an employee’s effectiveness at work. It is, therefore, essential that organisations identify the factors which influence employee happiness in order to enhance its cultural value-offering for employees and, in turn, increase their levels of job satisfaction. Job satisfaction is essentially the degree to which a person enjoys his/her job. It is the positive emotional state resulting from the evaluation of one’s work experience. This has profitable outcomes such as improved work performance. Furthermore, people who experience satisfaction in their jobs are better ambassadors for their organisation, demonstrate greater commitment, are more engaged and perform better within the organisation than their unhappy peers. Job satisfaction can be deemed an attitude. It is therefore important to understand the dimensions of the job, which are complex and interrelated in nature, in order to understand job attitudes. Organisational culture has been shown to influence the attitude and behaviour of employees through shared values and beliefs in the organisation. It is for this reason that there is a significant need to determine the factors in organisational culture that influence employee happiness and, in turn, job satisfaction. An organisation’s employees, through their participation and commitment, can be regarded as the most important source of success for the organisation. Organisational culture can therefore, greatly influence the efficiency and effectiveness of an organisation through its employees. Moreover, the culture of an organisation has a significant influence on the commitment and satisfaction of its employees. It inspires employees not only to feel committed to the organisation but also to perform well. The correlation between organisational culture and job satisfaction have been examined by various authors in the literature. All of these authors found a positive relationship between the two concepts. These conclusions show that the culture of an organisation can actually influence an employee’s job satisfaction and therefore his/her happiness. This research investigates the cultural value-offering of General Motors South Africa (GMSA) and its alignment to the needs of its employees. Until the end of 2012, an employee needs-analysis regarding employee happiness and his/her job satisfaction, was non-existent in the organisation. Towards the end of 2012 the organisation introduced a “Workplace of Choice” survey to perform an employee needs-analysis in order to investigate if there was a difference between employee needs and the organisation’s cultural value-offering. Another “Workplace of Choice” survey followed in 2014. This, however, was performed with the staff employees only and not with the hourly employees. Many organisations neglect to analyse the workplace needs of their employees to ensure that the organisation fully understands and is able to satisfy or accommodate these needs. Understanding employee needs is crucial to an organisation’s success. It is therefore important that the organisation investigates the employee needs to be able to align them with the cultural value-offering of the organisation. The purpose of this study is to advance the current understanding of Employee Happiness in the workplace by conducting a systematic analysis of the factors in Organisational Culture that influence Employee Happiness and, in turn, their Job Satisfaction in GMSA.

  • Description: Universities are facing growing pressure to contribute towards innovation which has social impact and which contributes to economic development. Researchers mainly in the Science and Engineering fields are the primary sources of innovation outputs from universities and as such their involvement in commercialisation activities directly adds to the growth of innovative outputs from publicly financed research. Technology Transfer Offices (TTO) have been established at universities across South Africa to foster the involvement of researchers in commercialisation activities, to champion the innovation conversation within higher education institutions and to progress innovations from concept to application in society. This study focussed on understanding the factors which enable or create a barrier to the involvement of researchers in commercialisation activities at the Nelson Mandela Metropolitan University. The key elements examined in this study include the researchers’ perception of enablers (monetary and nonmonetary incentives) and barriers to involvement at national, institutional and individual levels. This study undertook to understand the perceptions of researchers of enablers and barriers to involvement in commercialisation at the Nelson Mandela Metropolitan University. Researchers in the two faculties of Science and Engineering, Built Environment and Information Technology were approached to anonymously complete an electronic survey, the questions for which were developed from literature. The results from the survey were analysed using descriptive statistics and hypothesis testing. This study finds that a combination of incentives is necessary to enable researcher involvement and to lower barriers to involvement in commercialisation research. A set of recommendations based on the study are put forward on how such recommendations can be implemented.

  • Description: With the increase in electronic equipment implemented in various systems, as well as the increase in calculating power that these devices offer, designers are being empowered to make use of this power in real-time systems to diagnose and protect the systems themselves. This reasoning is too compounded by the focus on efficiency and safety in the design of complex systems, as well as the increasing expense and sensitivity of the electronic components themselves. With this in mind, this dissertation aims at developing a comprehensive measurement, control and reaction system for the electrical diagnosis and ultimately optimisation of complex electrical and electronic systems. This system will serve as a real-time diagnosis tool, which will enable the real-time diagnosis of various components in an electro-mechanical system, which can then be interpreted to determine the working state of the various components. Another sphere of this project will involve the accurate monitoring of the battery status as well as actively balancing the series connected batteries. The focus on the batteries will seek to prolong the life of the batteries, while being able to squeeze as much capacity out of them. The initial design and testing will be based on an AGV system implemented at VWSA, however a main goal throughout the design process will be modularity, i.e. the ease of implementation of this system in other systems. The key technologies used in the development of this system will still comprise of the components used in the original AGV, however new prototype components sourced from Microcare are used for the battery management system, while current sensors directly connected to the PLC’s analog input ports will be used for the active monitoring of currents distributed through the AGV.

  • Description: Theoretically, the use of Electronic Medical Records (EMRs) holds promise of numerous benefits in healthcare provision, including improvement in continuity of care, quality of care and safety. However, in practice, there is evidence that the adoption of electronic medical records has been slow and where adopted, often lacks meaningful use. Thus there is a clear dichotomy between the ambitions for EMR use and the reality of EMR implementation. In the USA, a legislative approach was taken to turn around the situation. Other countries such as Canada and European countries have followed suit (in their own way) to address the adoption and meaningful use of electronic medical records. The South African e-Health strategy and the National Health Normative Standards Framework for Interoperability in eHealth in South Africa documents both recommend the adoption of EMRs. Much work has been done to establish a baseline for standards to ensure interoperability and data portability of healthcare applications and data. However, even with the increased focus on e-Health, South Africa remains excessively reliant on paper-based medical records. Where health information technologies have been adopted, there is lack of coordination between and within provinces, leading to a multitude of systems and vendors. Thus there is a lack of systematic adoption and meaningful use of EMRs in South Africa. The main objective of this research is to develop the components required to engender meaningful use of electronic medical records in the South African healthcare context. The main contributors are identified as EMR certification and consistent, proper use of certified EMRs. Literature review, a Delphi study and logical argumentation are used to develop the relevant components for the South African healthcare context. The benefits of EMRs can only be realized through systematic adoption and meaningful use of EMRs, thus this research contributes to providing a road map for engendering the meaningful use of EMRs with the ultimate aim of improving healthcare in the South African healthcare landscape.

  • Description: Since the inception of the student supernumerary status, both globally and in South Africa, nursing and midwifery educators have been concerned about the clinical competencies of their students. Student clinical competency levels in South Africa are critical to midwifery practice, especially as most litigation against the Department of Health in South Africa concerns negligence in midwifery practice. In addition, the litigations mostly involve newly qualified midwives, thus suggesting a link with practice competency levels. Several challenges exist in the academic and practice environments regarding student learning, practice and clinical preparedness. Lack of support during clinical placement and a lack of facilities for use during clinical practice modules are among these challenges. Some students, due to the challenges they face with clinical learning and practice, fail to meet the practical competencies for examination entry requirements. Consequently, some of these students have to repeat the year or exit the programme. The current study sought to identify how to assist midwifery educators in their activities to prepare students for clinical placement readiness. The first objective of the study was to explore and describe the perceptions of midwifery educators regarding the need for additional measures to enhance the clinical preparedness of basic midwifery students before they are allocated to the clinical areas. The second objective sought to make recommendations that would further assist the midwifery educators to clinically prepare midwifery students before being allocated and placed in different clinical areas. A qualitative, explorative, descriptive and contextual research design was used for the study and the study was conducted at a nursing college in the Eastern Cape Province from August 2014 to January 2016. The research population consisted of midwifery educators at a nursing college and a purposive sampling technique was used guided by set criteria. Data were collected using focus group interviews. Four focus groups were used making a total of 17 participants. The principles applied for data analysis were those of Tesch’s method of data analysis, which were used to develop the themes and sub-themes. An independent coder assisted with the coding of the data for the purposes of trustworthiness. In addition, Lincoln and Guba’s model of trustworthiness consisting of the criteria of credibility, transferability, dependability and conformability was used to confirm the validity of the study while the ethical principles adopted were informed consent, justice, non-maleficence, privacy and confidentiality. The study found that the participants perceived numerous challenges that hindered the clinical preparedness of their students. These related to increased workload, lack of support from management and a lack of commitment on the part of students towards their studies. The participants also identified inconsistencies in clinical practice between the clinical midwives and the educators, and even among the educators themselves. This lack of consistency in turn causes confusion among the students and thus impacts negatively on their clinical practice preparedness. Based on these findings recommendations for clinical nursing practice, nursing education and research were made.

  • Description: Small and Medium Enterprises are the engines of economic development. In developing countries, they play an irreplaceable role in poverty alleviation through creation of jobs and contribution towards the countries’ gross domestic products. South Africa is faced with a challenge of high failure rate of SMEs despite the efforts by government to support and grow this sector. For a country to have a strong sustainable economy, sustainable and successful SME sector is necessary. Literature reviews have demonstrated that incorporating sustainability aspect into entrepreneurship improves the performance of businesses. Research on implementation of sustainability principles by SMEs is limited and SMEs have been left out in sustainability teachings and monitoring. The purpose of the study was to analyse the role played by entrepreneurial mind-set and entrepreneurial education on sustainability of SMEs. The research was conducted amongst 10 SME owners/managers with businesses located in the Buffalo City Metropolitan Municipality. Case study method using a semi-structured interview guide was conducted. Results were transcribed, analysed and interpreted. Results of the research demonstrated that SME owners/managers possess entrepreneurial mind-set, which is a necessity to run a successful business. There was also evidence that entrepreneurial education enhances entrepreneurial mind-set of SME owners/managers. SMEs owners/managers also demonstrated that they implement sustainability principles informally with no guiding documents. With regards to implementation of sustainability principles, there was no noticeable difference between SME owners/managers who had undergone entrepreneurship education and the ones who had not gone through entrepreneurship education. This highlighted the need to incorporate sustainability issues in entrepreneurship education courses. The study brings contribution towards building sustainable SMEs.

  • Description: The notion of Decent Work has been broadly advocated since 1999 by means of various International Labour Organisation (ILO) Conventions. Through these Conventions and as part of its Decent Work Agenda, the ILO strives to foster the creation of social and economic systems, capable of ensuring basic security and employment and adaptable to rapidly changing local and global economic circumstances. The Decent Work Agenda has been widely accepted as an important strategy to eradicate poverty and enable socio-economic development. It is submitted that the concept of Decent Work as contemplated by the ILO, firstly focuses on the payment of an income, which allows the working individual a good life. It secondly strives to ensure that everybody has an equal chance to develop themselves; that working conditions are safe; that there is no instance of child and forced labour; and that discrimination does not occur. The elimination of discrimination in the workplace is not only an ever-evolving pursuit, given that it continues to manifest in innumerable forms, but it has also proven to be an extremely pervasive pursuit as evidenced by the jurisdiction-specific literature review in this study. The jurisdictions focused on in this study are the United States of America, the United Kingdom and Australia. This study concerns itself with pay-related discrimination which strains ILO Conventions No 100 and 111. Convention 100 focuses on equal pay for equal work and Convention No 111 focuses on the elimination of all forms of discrimination in the workplace. In spite of extensive legislative developments in the various jurisdictions which form part of this study, enhanced by the creation of various practical mechanisms to enable the elimination of pay-related discrimination, the stubborn problem of discriminatory pay practices has survived structured and deliberate attempts to get rid of it. In South Africa, the amendment to section 6(4) of the Employment Equity Act, assented on 1 August 2014, specifically describes a difference in conditions of employment between employees of the same employer performing the same or substantially the same work or work of equal value based on any one or more of the grounds listed in section 6(1), as unfair discrimination. This amendment therefore seeks to prohibit such unfair discriminatory practices. Based on the newness of this amendment and the fact that courts have not yet delivered judgments arising from litigation related to this particular amendment, a sense of uncertainty exists with respect to the adequacy of the amended section 6 in the Employment Equity Amendment Act. If progress in the other jurisdictions in this regard is anything to go by, there is no reason to believe that the amendment to section 6 will be a panacea capable of addressing all alleged discriminatory pay practices.

  • Description: Communities around the globe are confronted by environmental challenges such as waste management. These challenges are further aggravated by factors such the increasing volumes of waste, landfills that are running out of capacity and scarcity of suitable land to construct new landfill sites. The National Waste Management Strategy requires participation from all members of society including households, businesses, community organisations, nongovernmental organisations, parastatals and the three spheres of government, to promote practices that minimise the volumes of waste generated. The purpose of the research was to assess and investigate the current waste management practices at the Cape Peninsula University of Technology (CPUT), and recommend a waste management system. The research employed a quantitative approach, where participants were asked to complete a survey questionnaire. A literature review was conducted on waste management at higher learning institutions, with particular focus on the contribution that a university can make in alleviating some of the adverse effects of waste management. The outcome of the review highlighted some of the opportunities and barriers that can either disrupt or augment the process of implementing a waste management system. The results from the research revealed that CPUT does not conform to the hierarchy of waste management, and there is no waste management policy in place. The effect of this is that the stakeholders were not satisfied with the lack of leadership on waste related challenges. By developing a policy, providing leadership, conducting awareness campaigns and prioritising environmental challenges such responsible management waste, could improve the image of the institution in the eyes if its stakeholders.

  • Description: The automotive components manufacturing sector is facing tremendous pressure to remain competitive in a global economy. The application of performance improvement techniques to optimise factor production inputs remains a key strategic mechanism to effect the necessary change towards competitiveness. The high failure rate of these programmes, however, is a risk factor that should be considered by manufacturing firms. The investment into the implementation of these programmes will yield no return if the organisational maturity profile is not considered. The expected gains may not materialise and the execution of critical projects may take much longer than required. It is for this reason that an approach towards selecting the correct Performance Improvement Programme to optimise the performance of companies is a business imperative. Through a better understanding of the relationships between Performance Improvement Programmes and Organisational Maturity Variables, implementation success rates can increase, leading to improved results and sustainability. The approach taken to this research was quantitative in nature. Various descriptive and inferential statistics were applied to the selected respondents from the Eastern Cape automotive sector. The respondents had a working knowledge of Lean Manufacturing, Total Productive Maintenance (TPM) and Six Sigma. The research instrument was administered through an online survey. The research sought to identify whether there was a relationship amongst the variables under the three identified constructs. The research also sought to establish whether there was a difference between the specific Performance Improvement Programmes’ and Organisational Maturity Variables’ relationships. This affirmed the use of a new framework that integrates the programmes on the basis of their relationship to Organisational Maturity Variables. The research also provided insight into the challenges of the industry from a performance perspective and linked these with the relationship between Organisational Maturity Variables and Organisational Performance Variables. This allowed the researcher to include this additional insight as a consideration in the integrated implementation framework developed as part of the research. The results show that good consideration should be given to the Organisational Maturity Variables as these variables are related to the successful adoption of Performance Improvement Programmes. The research also shows that Lean Manufacturing, Total Productive Maintenance and Six Sigma are related to an organisations’ maturity profile in different ways. These results support the integrated Performance Improvement Programme approach, using a common set of tools and selecting the necessary programme specific tools based on a firm’s maturity profile. The research affords industry a framework to aid in decision making considering the relationships tested as part of this research. The linkages between Performance Programmes, Organisational Maturity Variables and Organisational Performance Variables are now more specific in nature.

  • Description: This study explored the distribution of estuarine macrophyte genetic lineages, species and habitats in relation to environmental gradients at various spatial scales. A database was assembled to determine the area and species composition of different estuarine habitats. This can now be used to retrieve information as a baseline for further monitoring and conservation planning. Research has shown that macrophytes occur over a wide range of physiochemical conditions, suggesting that these species have great genetic and phenotypic variation to occupy broad niche ranges. In eight estuaries along the South African coast, sediment and groundwater characteristics were measured in quadrants spanning the salt marsh, ecotone and terrestrial habitats. The results suggested that, in the absence of competition and disturbance at the salt marsh-terrestrial boundary, salt marshes would be unaffected by sea-level rise; and they would migrate landward. However, disturbance at the landward margin of salt marshes has already resulted in changes in species composition and altered environmental conditions. This promotes the encroachment of terrestrial alien invasive plants, leading to a loss of connectivity. A holistic assessment of land-cover changes showed that only 28% of South African estuaries still remain in a natural state. The delineation of all estuaries needs to be consistent and inclusive of all estuarine physical and biological processes, to curb future changes. The research results have been used in national assessments of estuarine health; and they have made a significant contribution to estuary-management plans. In addition, three scientific articles have been published from the thesis; and two more are currently under review.
