- Description: While citizens require products and services to meet their needs, government goes about designing systems and processes to meet that need through the setting of goals and objectives. Many methods are adopted for that to happen. However, one of the ways that this occurs is through legislation and regulations and the formation of public entities. On the other hand, strategy is needed to devise techniques and plans to meet needs, goals and aspirations of government in the most efficient manner. At face value it would seem that the enactment of certain legislation and regulations seems to make the need for strategy obsolete especially since there is proliferation of national, provincial and local strategies that only need implementation. The purpose of this research is to determine the influence of legislation and regulations on strategy in public entities focusing on the Eastern Cape Province and using the Eastern Cape Development Corporation as a case study. The study focused on the assessment of the relationship between the public entities and the shareholder through the use of legislation and regulations. The context for the research is prefixed on creating an understanding of the public administrative system and especially the components of the New Public Management approach that deal with the principal-agent and public choice theory. The study assessed the public administrative system and its relationships in order to locate the use of legislation and regulations and public entities to deliver products and services to citizens. Likewise the concept of strategy was examined from three perspectives namely that strategy is about goal consciousness, strategy involves leadership and strategy is multifaceted in its nature. In order to undertake the study a document review was conducted on the legislation and regulations, semi-structured interviews were held with the principal or shareholder and a questionnaire was administered to executives and senior managers in public entities in the Eastern Cape Province. The findings revealed that there is a relationship between legislation and regulations and strategy on the one hand and on the other strategy appears to be ineffective due to a lack of planning, key role players’ involvement in the process, leadership, inflexible compliance and restrictive conditions. The research further found that strategy involves implementation of legislation and regulations which support the rise of the regulatory state. The study proposes a normative model that is built around defining the nature of strategy and predetermining the definition of roles in the system.

- Description: Given the importance of the potential of microfinance lending as a means of addressing poverty alleviation and fostering economic growth especially in developing countries, this study evaluates the influence of MFI lending on economic growth in Zimbabwe. Hence this study will provide empirical evidence as to whether MFI lending has an influence on economic growth in Zimbabwe. The study employed the Auto Regressive Distributed Lag (ARDL) Model using quarterly data from 2000- 2016. The stationary tests revealed that the dependent variable was I(1) and the independent variables had mixed stationarity properties l(0) and l(1). The ARDL Bounds Co-integration test showed that there is co-integration between microfinance and economic growth. The findings of the Error Correction Model indicated that microfinance positively influences economic growth. Furthermore, by investing in microfinance lending the economy will be positively influenced within a year’s time. This study provides justification for the pursual of capitalising on microfinance lending as well as for Developmental Institutions and the Reserve Bank of Zimbabwe to prioritise funding for microfinance lending.

- Description: The study aimed at investigating the influence of single parenting on the self-esteem and the sexual behaviour of adolescent males, with the aim to find out whether a relationship exists between single parenting, self-esteem and sexual behaviour or not by following a quantitative research method. Data was collected by means of self-administered questionnaire. The sample was made up of 226 adolescent males whom are high school learners and who aged between 12 and 21 from four schools around Raymond Mhlaba Municipality, Eastern Cape Province. For data analysis, Statistical Package for Social Sciences (SPSS) version 18 was used and it included descriptive statistics and inferential statistics. All statistical procedures were performed at 0.05 level of significance with 95 percent Confidence Interval. The study found that adolescent males from single parent households have positive selfesteem and responsibly sexual behaviours. In the study, the alternative hypothesis which stated that there is a positive correlation between single parenting and the adolescent males’ negative self-esteem was repudiated. On the other hand, the nullhypothesis which stated that there is no positive correlation between single parenting and adolescent males’ negative self-esteem and sexual behaviour was confirmed in the this study. Lastly, recommendations for the parents were made which include a good parent-child relationship that will create a safe space for effective communication and sex education which will likely prevent early sex debut. The importance of African families was underscored in this study, as such, it is deemed necessary then to build on this protective factor that could be helpful during adversities.

- Description: Orientation: Technology affects organisations both positively and negatively and in some instances technology factors can result in turnover intentions for certain employees of organisations. Research purpose: The main objective of the study was to investigate how technology-based job autonomy, technology-based job overload and technologybased job monitoring impact turnover intentions of employees. Motivation of the study: Exploring and understanding the relationship between technology factors and turnover intention amongst government employees to determine whether these factors affect government as much as they affect the private sector. Research design, approach and method: This research used a quantitative research approach. It drew a convenience sample of 182 employees (N= 182) from the South African Government. Main findings: The three main findings of the study were: Technology-based job autonomy was positively related to turnover intention. Technology-based job overload was found to be positively related to turnover intention. Finally, technology-based monitoring was found to be positively related to turnover intention. Practical/managerial implications: If organisations do not address the issue of monitoring and overload they are likely to experience many turnover intentions amongst the employees. Furthermore, the organisations with less autonomy are likely to lose their employees which means they will lose the resources that have been serving the organisation for a long time. This will also contribute to the organisation losing many funds as they would constantly have to train new employees. Contribution/value-add: The research adds value to the knowledge about the effects of technology factors on turnover intention by pointing out the reasons that lead to turnover intention.

- Description: Organisational success originates from employees’ willingness to use their abilities and skills so that an organisation continues to achieve its strategic objectives and thus remains competitive. The organisation’s task is to encourage and nourish these motivated employee inputs by putting effective rewards in place (Markova and Ford, 2011, p. 813.). In view of this, the purpose of this study was to gain a deeper understanding of the State IT Agency’s official performance-based rewards and to establish whether these rewards enhance employee motivation. A descriptive survey research design was adopted. The study targeted all 86 employees occupying non-managerial positions (Job level A1 – D1) at the State IT Agency – Eastern Cape. The study thus included the entire population. A structured questionnaire was used to collect data. Collected data was analysed using SPSS (Statistical Package for Social Sciences) for descriptive and inferential statistics. The results of the study were presented in frequency tables, cross-tabulations, histogram and line charts. The study revealed that intrinsically motivated employees are also motivated by financial and non-financial rewards. The research also showed that a statistically significant relationship exists between the number of years in the current position and employee motivation. This study’s results further revealed low levels of employee motivation as well as job dissatisfaction amongst the employees, dissatisfaction with the rewards provided by the organisation and that the State IT Agency is not providing employees with motivational factors perceived by employees as motivational. The study thus concluded that when the State IT Agency rewards outstanding employee performance with a performance-based bonus and a salary increase such employees’ motivation levels should be enhanced. It was recommended that the State IT Agency should design a total rewards strategy for the purpose of maximising the impact of various rewards on employee motivation. The State IT Agency should also focus on eliminating factors leading to employee dissatisfaction before implementing the proposed total rewards strategy because dissatisfied employees cannot be motivated.

- Description: The purpose of this study was to assess the level of transformational and transcendental leadership adopted by SMME owners, and to investigate the subsequent influence on the engagement and job performance of employees working in SMME’s in Port Elizabeth. These small, medium and micro enterprises (SMME’s) were selected as they play a fundamental role in South Africa’s economy. These organisations drive innovation, facilitate job creation and foster economic growth. However, these SMME’s are facing an increased failure rate which has an impact on continuity for the foreseeable future. A significant reason for the increased failure rate has been identified as poor leadership practice which significantly influences the engagement and job performance of employees in SMME’s. To address and solve this problem, the research design and methodology followed a quantitative approach. A quantitative approach was deemed to be the most appropriate when the objectives and nature of the study were revised. The population was identified to be all employees working for the small, medium and micro-sized enterprises conducting business in Port Elizabeth in the Eastern Cape Province. The sample for this study was selected using judgement and convenience sampling as it was inexpensive and respondents were more available which enabled a larger sample size quicker (Wegner, 2016, p.161). A cross-sectional study then supplemented these sampling methods. Lastly, an empirical study was conducted to test the hypotheses formulated in Figure 1.1. The findings from the empirical study indicated that transformational leadership significantly influenced engagement and trancendental leadership significantly influenced job performance. The findings also indicated that the demographic variables in the study had no influence on the level of transformational and transcendental leadership that SMME owners and management exhibit in the workplace. The majority of respondents agreed that a high level of transformational and transcendental leadership was currently being exhibited by SMME owners and management. Recommendations were made in an effort to improve the current levels of transformational and transcendental leadership of SMME owners and management. There would be a subsequent impact on the engagement and job performance of employees. When employees are satisfied, there is a greater sense of responsibility and integrity which results in greater job performance. There is also a positive ripple effect on the performance of the organisation. This paints a positive picture for South Africa’s economy and SMME continuity.

- Description: With the increase in global trade, an escalation of industry competition, greater customer expectations and increasingly larger and more complex supply chains, third-party logistics (3PL) providers play an increasingly important role in international trade. Driven by globalisation and the advances in information technology, 3PL services have experienced unprecedented growth around the world. Given its prominence in global trade, 3PL service providers have, since the late 1980’s, attracted increased scholarly attention and as such, many practitioners regard 3PL providers as integral to external parties that may be consulted for any and all matters related to logistics service, and that are often engaged in the strategic coordination of businesses supply chain activities. Although the body of literature concerned with environmental issues in disciplines such as production and marketing have grown, similar literature involving logistics has been scarce, but expanding. Notwithstanding this growing literature, more research on environmental issues within the logistics industry is required, since the logistics service industry may have a greater negative environmental impact than other service sectors. Despite extensive scientific literature on the outsourcing of logistics functions and 3PL strategy, comparatively fewer studies on environmental sustainability exist in the 3PL industry. It is against this background that the main research question to be addressed in this study is which factors influence the intentions of 3PL service providers to adopt environmentally sustainable practices. A quantitative research methodology was adopted in this study to empirically test the proposed hypothetical model. By means of non-probability sampling, namely convenience sampling, a total of 122 3PL service providers were targeted within Nelson Mandela Bay during the empirical study. This was done by means of a survey using a self-administered structured questionnaire. Descriptive statistics and frequency distributions were utilised to summarise the data collected from the sample. To test the hypothesised relationships in the theoretical model, multiple regression analyses were used. The influence of three internal factors (management support, organisational culture and availability of resources) three external factors (competitive pressure, customer pressure and government influences) on the intention of 3PL service providers to adopt environmentally sustainable practices xii were assessed. The findings of this analysis showed that management and organisational support, customer pressures and government influences and have a significant influence on the intention to adopt environmentally sustainable practices for these businesses. The findings of this study have contributed to the body of knowledge regarding the intentions of 3PL service providers to adopt environmentally sustainable practices. The study used a sound and well-developed research design and methodology which have been justified and applied. This can be utilised by other similar studies to conduct empirical research in the field of adopting sustainable business practices. The measuring instrument and hypothetical model developed can also be used by organisations in other industries to investigate intentions to adopt sustainable practices. This study also provided useful and very practical guidelines to 3PL service providers as to ensure effective adoption of sustainable business practices.

- Description: The study addresses the nature of Colombian sustainable social development and the internationalisation of higher education (iHE). This intersection is analysed within various theoretical paradigms surrounding social sustainable development and the internationalisation of higher education. This study aims at reviewing the activities of Higher Education Institutions (HEIs) which focus on internationalisation. The analysis focuses on the manner in which HEIs in Colombia approach internationalisation vis-à-vis social sustainable development, and emphasis is made on knowledge transfer, research and community engagement. Using the theories of sustainable development, the iHE, in terms of practises and policies, are assessed. Within a mixed-methods approach, data gathered from Colombian university heads (16 presidents and vice-presidents) and 133 individuals responsible for internationalisation affairs is analysed. Concurrent triangulation is used to help introduce a series of themes and sub-themes derived from the qualitative and quantitative information. Within a social constructionist framework, this study has a twofold purpose. On the one hand, it is sought to identify and understand the challenges for Colombia’s academic internationalisation; on the other, an in-depth approach is presented in relation to the way different stakeholders perceive the society-HE internationalisation nexus. The major findings of the study indicate that there is a need to clarify and revise Colombia’s Higher Education policy to address both the education needs of the society and its social development requirements. It was also found that higher education internationalisation could act as an important agent of social change.

Within a social constructionist framework, this study has a twofold purpose. On the one hand, it is sought to identify and understand the challenges for Colombia’s academic internationalisation; on the other, an in-depth approach is presented in relation to the way different stakeholders perceive the society-HE internationalisation nexus. The major findings of the study indicate that there is a need to clarify and revise Colombia’s Higher Education policy to address both the education needs of the society and its social development requirements. It was also found that higher education internationalisation could act as an important agent of social change.

- Description: A 2,6-dibrominated 3,5-distyryl boron-dipyrromethene (BODIPY) dye with a moderately high singlet oxygen quantum yield was encapsulated in Pluronic® F-127 micelles, and its dark cytotoxicity and photodynamic activity were investigated on the human breast adenocarcinoma MCF-7 cell line. The BODIPY dye exhibited very low dark toxicity and a significant PDT effect when added in drug formulations consisting of 5.0% (v/v) DMSO in supplemented Dulbecco’s modified Eagle’s medium (DMEM) and as Pluronic® F-127 micelle encapsulation complexes in supplemented DMEM alone. An IC50 value of 4 ± 2 μM was obtained when the BODIPY dye was encapsulated in Pluronic® F-127 micelles during in vitro photodynamic activity studies in MCF-7 cancer cells with a 660 nm light emitting diode.

- Description: AA9 proteins are metallo-enzymes which are crucial for the early stages of cellulose degradation. AA9 proteins have been suggested to cleave glycosidic bonds linking cellulose through the use of their Cu2+ coordinating active site. AA9 proteins possess different regioselectivities depending on the resulting cleavage they form and as result, are grouped accordingly. Type 1 AA9 proteins cleave the C1 carbon of cellulose while Type 2 AA9 proteins cleave the C4 carbon and Type 3 AA9 proteins cleave either C1 or C4 carbons. The steric congestion of the AA9 active site has been proposed to be a contributor to the observed regioselectivity. As such, a bioinformatics characterisation of type-specific sequence and structural features was performed. Initially AA9 protein sequences were obtained from the Pfam database and multiple sequence alignment was performed. The sequences were phylogenetically characterised and sequences were grouped into their respective types and sub-groups were identified. A selection analysis was performed on AA9 LPMO types to determine the selective pressure acting on AA9 protein residues. Motif discovery was then performed to identify conserved sequence motifs in AA9 proteins. Once type-specific sequence features were identified structural mapping was performed to assess possible effects on substrate interaction. Physicochemical property analysis was also performed to assess biochemical differences between AA9 LPMO types. Molecular dynamics (MD) simulations were then employed to dynamically assess the consequences of the discovered type-specific features on AA9-cellulose interaction. Due to the absence of AA9 specific force field parameters MD simulations were not readily applicable. As a result, Potential Energy Surface (PES) scans were performed to evaluate the force field parameters for the AA9 active site using the PM6 semi empirical approach and least squares fitting. A Type 1 AA9 active site was constructed from the crystal structure 4B5Q, encompassing only the Cu2+ coordinating residues, the Cu2+ ion and two water residues. Due to the similarity in AA9 active sites, the Type force field parameters were validated on all three AA9 LPMO types. Two MD simulations for each AA9 LPMO types were conducted using two separate Lennard-Jones parameter sets. Once completed, the MD trajectories were analysed for various features including the RMSD, RMSF, radius of gyration, coordination during simulation, hydrogen bonding, secondary structure conservation and overall protein movement. Force field parameters were successfully evaluated and validated for AA9 proteins. MD simulations of AA9 proteins were able to reveal the presence of unique type-specific binding modes of AA9 active sites to cellulose. These binding modes were characterised by the presence of unique type-specific loops which were present in Type 2 and 3 AA9 proteins but not in Type 1 AA9 proteins. The loops were found to result in steric congestion that affects how the Cu2+ ion interacts with cellulose. As a result, Cu2+ binding to cellulose was observed for Type 1 and not Type 2 and 3 AA9 proteins. In this study force field parameters have been evaluated for the Type 1 active site of AA9 proteins and this parameters were evaluated on all three types and binding. Future work will focus on identifying the nature of the reactive oxygen species and performing QM/MM calculations to elucidate the reactive mechanism of all three AA9 LPMO types.

- Description: The promulgation of the 2010 Constitution of Kenya introduced socio-economic rights (SERs) amid widespread poverty and rising inequality. This study seeks to answer the overarching question, what role can the Kenya National Commission on Human Rights (KNCHR) play in promoting, protecting and monitoring SERs in Kenya? Further research questions included whether the KNCHR has the requisite powers to perform its mandate and what lessons could be learned from the South African context. The research sought to understand how the local context affects the ability of KNCHR to carry out its mandate. Likewise, it analyses some of the contributions KNCHR has made in the promotion and protection of SERs while identifying the challenges the Commission faces in carrying out its mandate. Several methodologies were utilised to answer the research questions above. The methodologies included the doctrinal method, analysis of secondary sources and interviews with key informants. A comparative legal research methodology was also employed, with the SAHRC being used as a case study on how NHRIs can promote, protect and monitor SERs. The findings from the research argue that the Paris Principles provide the minimum guidelines on the establishment of NHRIs. Compliance with these Principles has not necessarily guaranteed the effectives of NHRIs. Any assessment of an NHRI should be based on its performance and legitimacy considering the local factors obtaining within its jurisdiction. The domestic protection and judicial enforcement of human rights in Kenya, though crucial to the realisation of SERs, has been fraught with challenges. These challenges have meant that the realisation of SERs has been curtailed and necessitated complementary institutions for human rights to be realised. Given the country’s constitutional architecture, the KNCHR was one such institution that could complement the role of the judiciary given its wide mandate. With SERs a new feature of the 2010 Constitution, the KNCHR had to find ways to promote SERs in the country considering the local peculiarities such as poverty, a highly political climate and lack of political goodwill from the legislature and executive sometime characterised by open hostility. These challenges and the new nature of these rights called for a comparative study with the SAHRC given some similarities between the two jurisdictions. The SAHRC provided valuable lessons having had more experience in dealing with SERs while navigating similar challenges the KNCHR faced or might face. The findings of the research prompted recommendations directed at the KNCHR and other stakeholders, specifically the legislature and executive on how to address the challenges curtailing the performance of the KNCHR in general and particularly ways in which the Commission could go about in promoting, protecting and monitoring SERs.

- Description: Grain forms a staple part of the majority of the global populations’ diets and it is used a raw material for animal feed in many countries. The envisaged increase in population in years to come can be expected to increase the demand of grain globally. Grain production is expected to fulfil energy requirements since developed countries are increasingly utilising grain as an alternative energy source to reduce the negative environmental effects caused by energy derived from fossil fuels. The grain value chain in South Africa consists of grain producers, input suppliers, millers and processors, as well as traders and speculators. The majority of the grain producers in South Africa are commercial farmers who play an important role in the economy of the country. South Africa trades their grain commodities on the Johannesburg Stock Exchange where grain prices are controlled by different social, economic and political factors. This gives rise to grain commodity price volatility because of its sensitivity to market changes. This study focuses on the difficulty faced by the grain producers and stakeholders in the value chain, like traders and speculators, who are exposed to price related risks as a result of the volatility of the grain commodity. It presents the current mitigation strategies that are available to hedge against these risks. Research shows that the current mitigation strategies are not being fully utilised by the grain producers because of their lack of skills and the time to search through and make sense of the datasets on the abundance of factors that influence the grain commodities market. This study presents a market intelligence approach as a solution to the grain volatility price risk. Market intelligence is utilised to enable the prediction of grain prices and to discover the factors that are driving the market at different periods. This is achieved by utilising neural networks and relative importance statistical techniques. In this study, it was found that the impact of the different factors changes from time to time. It proposed a technique for making sense of the changes in the prices of grain commodities. A framework for the implementation of market intelligence to mitigate against price volatility risks is proposed as an output of this study. The impact of the findings of this study to the grain producers and stakeholders in the value chain is that they can have insight on which factor is driving the market at a given period. This would enable then to adjust their activities and enable increased profitability.

- Description: This study is about the Council for the Development of Social Science Research in Africa (CODESRIA). Conceived in 1964 and formalised in 1973, CODESRIA is the longest-standing pan-African intellectual organisation on the continent. It was established with the primary objective of fostering greater collaboration between African scholars, and has acquired a reputation for challenging the marginalisation and fragmentation of African scholarship. However, there has been no systematic account of this important organisation. This study aims to cast light on this organisation and its intellectual contributions in the post-independence period. It examines CODESRIA as a knowledge commons - a community of scholars that creates, manages and shares intellectual goods outside of the state and the market. It asks: what factors have shaped CODESRIA as a pan-African knowledge commons in the context of epistemic inequality? As a way of answering this question, it examines three key debates: the different meanings of pan-Africanism in CODESRIA, CODESRIA’s defence of the academic project during structural adjustment, and African feminists’ struggles to change CODESRIA. These debates exemplify the ways in which different generations of African scholars in the post - independence period have sought to make sense of and respond to the problems of inequality - both outside of CODESRIA and within CODESRIA. This thesis approaches CODESRIA as a case study. It combines a document analysis with semi-structured interviews to construct and critique key intellectuals' understandings of the organisational design and practices of CODESRIA, the nature of its community and intellectual work. It supplements this with a descriptive analysis of CODESRIA’s bibliometric and administrative data. The study finds that CODESRIA has forged a distinctive form of pan-Africanism that offers a non-governmental and intellectual alternative to state-centric and bureaucratic forms of pan-Africanism. As a powerful counter-narrative to prevailing ideas of African intellectual inferiority, pan-Africanism has been an important motivational source for establishing and cohering CODESRIA’s community. Although its pan-African organisational form has been complicated by the enduring influence of colonial frameworks and limited by the the material and institutional weaknesses of African universities, it has nevertheless acted as a mode of collective enquiry for troubling and expanding the colonial conception of Africa. This study further finds that structural adjustment fundamentally reshaped the intellectual and material underpinnings of CODESRIA with complex and ambiguous results. In the short term, CODESRIA’s analysis of structural adjustment led to considerable intellectual and organisational innovation so that it grew in size and influence. In the long-run, however, structural adjustment eroded the public universities upon which CODESRIA relied. This eroded the mechanisms to maintain its intellectual vigour and democratic character, and increased CODESRIA’s dependency on donors. The study also finds that the struggles of feminist scholars to change unequal gender norms in CODESRIA have been a source of significant intellectual and organisational renewal. Contestations over gender inequality within CODESRIA have given rise to a distinctive form of African feminism, which emphasises the historicity of gender relations in ways that reject essentialist and teleological accounts of African societies. Feminist struggles have also given rise to new standards of scholastic excellence that mark a meaningful departure from the skewed standards introduced under colonial rule. Nevertheless, the persistent minoritisation of female scholars in CODESRIA has significantly limited their capacity to effect institutional change, such that the ghettoization of feminist scholarship and the hollowing out of feminist discourses on gender remains a constant threat. The central argument of this study is that inequality can motivate marginalised members to engage in the collective action required to create and reshape knowledge commons, but it can also constrain their collective action and threaten the long-term sustainability of the commons. The collective agency of marginalised individuals is therefore central to the flourishing of knowledge commons. Second, knowledge commons are intimately dependent on public goods, such as universities. Public goods are plausibly the source, and therefore the limit, of knowledge commons’ capacity to flourish over the long-term. As a consequence, it is likely that knowledge commons are complements to public goods provision, rather than substitutes. Rethinking the knowledge commons in terms of the predicaments of African intellectual communities, I contend, provides new ways of understanding the possibilities, constraints and contradictions of knowledge commons in an unequal world. This study contributes to the empirical literature on African intellectual communities. In particular, it provides critical knowledge on a scholarly community that has not only endured, but has managed to thrive in a context of profound economic and political instability. This provides an indication of the institutions, practices, and intellectual resources that are required to ensure that African knowledge systems flourish over the long-term. This study also makes a theoretical contribution to the literature on knowledge commons, which are largely theorised using examples from the global North. It shows how reconceptualising knowledge commons in terms of inequality opens up new lines of empirical investigation. Building on existing commons research, it develops a methodological framework for comparative research on southern knowledge commons, which may also be of use for investigating commons in general.

- Description: The history of South Africa has been shaped by the dictatorial laws of the apartheid regime which ushered an order of domination and segregation, ostensibly to perpetuate social inequality along racial lines. In the process the white minority intended to stifle the potential of the black communities and render them subservient and unable to question or stand against white domination. To this effect the white minority instituted discriminatory laws such as The Native Land Act of 1913, among others, in a bid to give impetus to the dispossession of black communities of their land. The dispossessed people were eventually forcefully removed from their land and posted to the middle of nowhere, at the so-called Ciskei and Transkei territories. In these homelands, as these states were called, the black South Africans started to feel the pinch of apartheid more. The worst of all, these people were impoverished since they had no jobs. It is only after the emergence of the democratic dispensation, in 1994, that the transformative action was taken even though it failed to deliver as expected. In the process, the Department of Rural Development and Land Reform was established with a mission to transform and redress the evils of the past by either giving the dispossessed back their land, alternative land or financial compensation, among other arrangements. However, since it was difficult to give people back their land, the most popular option became financial compensation. This choice, it has been argued, was influenced by the high levels of poverty, high unemployment rate, low rural household incomes and poor levels of education – instances which may have led to the beneficiaries attaching little or no value towards land ownership and other possible means of land restitution. As such, ii the majority of the community thought that financial compensation would lead to sustainable livelihood and would, therefore, not allow such opportunity to slip off their hands. However, more than two decades after the emergence of the democratic dispensation, the popular financial compensation has not yielded the expected results. Yet there is a Cata community which, being among the first members of the society to successfully claim for land restitution opted for land restoration and financial compensation award was given to claimants to pay for houses that were demolished during the betterment process. Out of the award, the Cata community took a calculated risk and invested 50% of the compensation money towards the development and improving the livelihood of the Cata community. This being the case, the study sought to explore to what extent the restitution programme (with the financial compensation option) could succeed in improving the livelihoods of the Cata community. In a way, while this statement is the main objective of the study, it also satisfies the key question of the study. It will ensure that the Cata community, in their attempt to lead sustainable livelihoods, will become creative and ensure that people have good paying jobs, they budget and rationalise before using money; and that they are even prepared to take calculated risks in order to succeed, just as the Cata communities have done. No doubt this would ensure that every member of the society enjoys and is regaled by the fruits and transformative actions of the new democratic dispensation. Qualitative research methodology has been selected to conduct research of this study because it requires a researcher to dig deep to the research problems and give out rich research findings with insight because community experiences can only be understood qualitatively not through the statistics. The main findings of this study among others are that financial compensation should be linked with iii development in order to sustain livelihoods of the rural poor as the case has been with Cata community. A number of communities who opted financial compensation did not lead a sustainable livelihood instead they either became poorer or fell victims of poverty because they fail to use their financial compensation award wisely.

- Description: The history of South Africa has been shaped by the dictatorial laws of the apartheid regime which ushered an order of domination and segregation, ostensibly to perpetuate social inequality along racial lines. In the process the white minority intended to stifle the potential of the black communities and render them subservient and unable to question or stand against white domination. To this effect the white minority instituted discriminatory laws such as The Native Land Act of 1913, among others, in a bid to give impetus to the dispossession of black communities of their land. The dispossessed people were eventually forcefully removed from their land and posted to the middle of nowhere, at the so-called Ciskei and Transkei territories. In these homelands, as these states were called, the black South Africans started to feel the pinch of apartheid more. The worst of all, these people were impoverished since they had no jobs. It is only after the emergence of the democratic dispensation, in 1994, that the transformative action was taken even though it failed to deliver as expected.

- Description: The aim of this research is to investigate the constitutional, common law and legislative remedies available to protect the rights of minors against cyberbullying in South Africa and whether these laws are in line with the relevant international instruments. The study focuses on the protection of the rights of minors online as the most vulnerable group in society. The internet was not originally created to be used by minors, therefore, children are subject to more risks on the internet like cyberbullying. Cyberbullying results in the infringement of the rights to privacy, dignity and reputation among others. There are several remedies available in South African private law to protect the rights of minors. However, the rights of the victim must be balanced against the perpetrator’s right to freedom of expression, taking into consideration the best interests of both children. The remedies available are in line with some international instruments safeguarding human rights but there are a number of weaknesses in relation to the application of these remedies to instances of cyberbullying. For example, an interdict cannot be issued in instances where the cyberbully is anonymous. The current legislative framework, although also in line with relevant international instruments, is not going far enough to protect children against cyberbullying. In addition, the term “cyberbullying” is not specifically defined in any of the Acts, which may create challenges in the prosecution of the crime. Fortunately, there are a number of Bills in the pipeline that aim to address the gaps in the current law. Several provisions of the Bills also correlate with relevant international instruments. However, there is a need to revise the proposed Bills in order to sufficiently protect minors against cyberbulling. This study also proposes recommendations relating to some of the inadequacies of the law in this regard.

- Description: The recent student protests that erupted in the South African higher education landscape in 2015 and 2016 suggest that research concerning student experiences in our institutions has become all the more crucial. In light of this, our chapter argues for theoretically rigorous and conceptually rich approaches to research on the student experience, without which we will not be in a position to address the significant concerns raised by these protests. There is, of course, already a robust body of work detailing the student experience (for example Case, 2013; Case, Marshall, McKenna, and Mogashana, 2018; Walker and Wilson-Strydom, 2017). However, questions are often raised about the extent to which such research is being drawn on in subsequent studies (Niven, 2012) and this suggests that limited accounts of student experience remain dominant despite this body of research (Boughey and McKenna, 2016). It thus seemed important to make sense of the ways in which current research on student experience is being constructed.

- Description: Ultra-high precision machining is a material removing process under the nanotechnology regime whereby the highest dimensional accuracies are attained. Critical components for optical devices and optical measuring systems are mainly produced through ultra-high precision machining. Their mass production is usually implemented by utilising optical moulds. Aluminium alloys have proven to be advantageous and very commonly used in the photonics industry for moulds. This ever-increasing use and demand within optics have led to the development of newly modified grades of aluminium alloys produced by rapid solidification in the foundry process. The newer grades are characterised by finer microstructures and improved mechanical and physical properties. The main inconvenience in their usage currently lies in their very limited machining database. This research investigates the machinability of rapidly solidified aluminium, RSA 905, under varying cutting conditions in single point diamond turning. The machining parameters varied were cutting speed, feed rate and depth of cut. The resulting surface roughness of the workpiece and wear of the diamond tool were measured at various intervals. Acoustic emissions and cutting force were also monitored during machining. The results were statistically analysed and accurate predictive models were developed. Generally, very low tool wear, within 3 to 5 μm, and very low surface roughness, within 3 to 8 nm, was obtained. Acoustic emissions recorded were in the range of 0.06 to 0.13 V and cutting forces were in the range of 0.08 to 0.94 N. The trends of the monitored acoustic emissions and cutting force showed to have a linked representation of the tool wear and surface roughness results. Contour maps were generated to identify zones where the cutting parameters produced the best results. In addition, a range of machining parameters were presented for optimum quality where surface roughness and tool wear can be minimised. As the machining is of a nanometric scale, a molecular dynamics approach was applied to investigate the underlying mechanisms at atom level. The nanomachining simulations were found to have a correlation to the actual machining results and microstructural nature of the alloy. This research proves that rapidly solidified aluminium is a superior alternative to traditional aluminium alloys and provides a good reference with room for flexibility that machinists can apply when using rapidly solidified aluminium alloys. Efficiency could be improved by reducing the required machining interruption through effective monitoring and performance could be improved by maintaining quality and extending tool life through parameter selection.

- Description: This study sought to investigate the management of court records for justice delivery at Alice Magistrate Court in the Eastern Cape, South Africa. The objectives of the study were to find out the extent to which records are managed in Alice Magistrate Court; to establish the existing infrastructure for the management of court records in Alice Magistrate Court; to find out the extent to which the management of court records in Alice Magistrate Court comply with legislative and regulatory requirement; to find out the influence of the current management of court records in court processes, to find out the challenges of the management of court records in Alice Magistrate Court, and to make recommendations on the improvement of the management of court records in Alice Magistrate Court. The record life cycle and the records continuum models underpinned the study based on post-positivist paradigm that allowed the use of both quantitative and qualitative approaches. The court manager, magistrate, prosecutor, interpreter, court clerks, and court users at the Alice Magistrate Court formed the sample for the study. Quantitative data were coded and analysed using Office Microsoft Excel 2010 while qualitative data was analysed using content analysis. The major finding indicated weak records management practices that resulted into loss and misplacement of records, and postponements of many cases that led to delays in justice delivery by the court. The study recommended the enhancement of the records management programme by continuous training of court personnel, the adoption of electronic records management system, and the review of the current records security and tracking systems.

- Description: Records management is a major element for accountability in the municipality. The research topic was “the management of records for accountability by the municipalities in the Eastern Cape Province, South Africa: A case study of Mbizana Local Municipality”. The objectives of the study were: to find out the types of records management programme maintained by Bizana Local Municipality, to describe available infrastructure that supports the records management programme in Mbizana Local Municipality, to find out the extent to which the management of records in Mbizana Local Municipality complies with statutory and legislative requirements, and to find out the possible constraints that affects the records management programme in Mbizana Local Municipality. The study was conducted in Mbizana Local Municipality which is under Alfred Ndzo District Municipality in Eastern Cape, South Africa. The sample was municipality staff and the residents of the municipality. The study used both qualitative and quantitative research methods. The findings were that Mbizana Local Municipality has a records management programme which is important for accountability, however, there is a need for security maintenance. In addition, the findings were that the municipality need to train its registry staff about records management or hire new people who are capable of managing records. The researcher recommended that Mbizana Local Municipality should provide more training to registry staff on the management of records. The municipality should introduce electronic records management system since nowadays records are created electronically. Electronic records can be easily retrieved when needed for accountability. Also the municipality should allow the public to have access to records.

- Description: This study analyses the status and management of mangroves in Mozambique and how the management system addresses the threats to mangrove conservation. A comprehensive analysis of the country forest condition and management status was conducted based on a literature review and informal interviews with key informants. GIS and remote sensing techniques combined with groundtruthing were used to assess the impact of natural and human threats on mangroves based on changes in NDVI (Normalised Difference Vegetation Index) and cover area. These studies were conducted at the Save River and Cabo Delgado province, respectively. Structural data of the mangrove forest were collected during field visits to assess changes in structural parameters and compare impacts in different forests or locations within the same forest. Finally a community-based management system in Nhangau (Sofala province) was analysed in order to assess the efficacy as a management tool to meet mangrove conservation objectives. Mozambique has an estimated mangrove cover area of 3 054 km2. In general there is a trend of decrease in cover around major human settlements, while remote areas show an increase in cover as documented in Maputo Bay (175.96 km2, decreasing within Maputo town) and Zambezi Delta (370.34 km2, increasing), respectively. Mangroves are mostly used for wood resources, salt production and fishing grounds. However, urban development, saltpans, logging and natural phenomena such as floods and cyclones are a threat to these systems. Mozambique has 27% of its mangroves protected in conservation areas. At places like the Quirimbas National Park, this protection is not effective due to illegal cutting and poor enforcement. The Mozambican institutional and legal frameworks provide protection to mangroves at all levels and prohibit all forms of degradation and unsustainable use. However law enforcement and institutional functioning is weak. There is also a need to update the legislation by adding specific aspects related to mangroves, such as regulating invertebrate collection and defining customary use. At the Save River changes in NDVI indicated that 63.42 km2 of mangrove (47.8%) were affected by cyclone Eline. Field investigations 11 years after the cyclone showed that there was substantial recovery in the protected creek forest but changes in sedimentation prevented recovery in the seaward sites that are exposed to storm surges and wind. This study highlighted the necessity for field based investigations in addition to remote sensing as results showed site specific differences. The percentage of living trees at the creek forest ranged from 71 to 97% from the outer to inner forest. Also species density was higher at the creek sites from the outer (101 ± 63 tree/ha) to inner forest (488 ± 111 trees/ha) as was the complexity index (0.09 to 0.25 respectively). At the seaward forest the percentage of living trees increased from 0 to 79% from the outer to inner forest. Seedlings (up to 40 cm height) dominated the understory throughout the forest however the outer edge of the seaward forest had no regeneration at all. This forest recovered naturally from the cyclone, however it is important to maintain low exploitation levels to ensure forest resilience in case of similar future impacts. The frequency and intensity of cyclones is expected to increase with climate change and thus the results can contribute to management strategies and climate change adaptation plans. 3 Human impacts were investigated at a peri-urban, rural and island setting in Cabo Delgado province. It was hypothesized that peri-urban forests would be more impacted. However an analysis of LandSat images showed that mangrove cover at the peri-urban site actually increased by 22.7% between 1991 and 2013; while rural forests lost 23.2% of its area during the same period. Field studies showed that there was no significant difference between average tree density for the different sites (p= 0.16) and the low complexity indices indicated young disturbed forests. At the peri-urban and rural sites, the tree diameter class 5.1-8 cm was targeted for extraction, while at the rural island all size classes were targeted. The proportion of stump:living trees was 1:11 at the peri-urban site; 1:9 at the rural site and 1:4 at the rural island. Most of the standing trees were crooked and not suitable for building purposes. The small extractive use of mangroves at the peri-urban site could be related to the fact that the dominant ethnic group has kept its essentially agricultural habits while at the rural site the people are typically fishermen and marine invertebrate collectors that rely on mangroves and marine resources for their livelihoods. Proposed management measures for these sites include raising awareness at all sites and conducting mangrove restoration at the peri-urban (abandoned saltpans and aquaculture farm) and rural sites. A community-based management system at Nhangau (Sofala province) was analysed in order to assess how this has achieved management conservation objectives. After facing several impacts due to mangrove degradation, the community of Nhangau engaged in mangrove replanting and management. The main management actions were (1) reduction of extractive uses, (2) continuous awareness and mangrove planting and (3) law enforcement. The restoration interventions started in the late 1990s by the local government in partnership with the local community and NGOs. Currently (2018), most of the activities are led by the local Natural Resources Management Committee (NRMC). Ten hectares of mangrove were planted between 1996 and 2017, and according to the local community the restored areas are already providing important ecological services such as temperature regulation. There are several challenges such as, limited functionality of the NRMC and its interaction with other stakeholders, Government representatives and local NGOs. There is also a lack of alternative livelihoods for mangrove cutters and the wider Nhangau community. Improvements to the system include better integration of local government representative structures with the civil society organizations (NGO and NRMC), law enforcement, financing of the appropriate sustainable use practices, environmental awareness and education and the promotion of appropriate NRMC functionality and representation. With these improvements this community-based management system can be effective as a management tool to meet mangrove conservation objectives and serve as a replicable model for other parts of the country. In conclusion, this research has documented both anthropogenic and climate-related impacts on mangroves in Mozambique and highlighted options for mangrove management focusing at strengthening the community –based management of mangroves in rural sites. Mangrove management would improve significantly by strengthening the legislation on specific mangrove issues combined with law enforcement and better community organization and their training and sensitization to manage mangrove resources at the local level. Such actions will increase the resilience of forests, allowing sustainable use and faster recovery in case of impacts by either anthropogenic or natural factors such as cyclones.

Structural data of the mangrove forest were collected during field visits to assess changes in structural parameters and compare impacts in different forests or locations within the same forest. Finally a community-based management system in Nhangau (Sofala province) was analysed in order to assess the efficacy as a management tool to meet mangrove conservation objectives. Mozambique has an estimated mangrove cover area of 3 054 km2. In general there is a trend of decrease in cover around major human settlements, while remote areas show an increase in cover as documented in Maputo Bay (175.96 km2, decreasing within Maputo town) and Zambezi Delta (370.34 km2, increasing), respectively. Mangroves are mostly used for wood resources, salt production and fishing grounds. However, urban development, saltpans, logging and natural phenomena such as floods and cyclones are a threat to these systems. Mozambique has 27% of its mangroves protected in conservation areas. At places like the Quirimbas National Park, this protection is not effective due to illegal cutting and poor enforcement. The Mozambican institutional and legal frameworks provide protection to mangroves at all levels and prohibit all forms of degradation and unsustainable use. However law enforcement and institutional functioning is weak. There is also a need to update the legislation by adding specific aspects related to mangroves, such as regulating invertebrate collection and defining customary use. At the Save River changes in NDVI indicated that 63.42 km2 of mangrove (47.8%) were affected by cyclone Eline. Field investigations 11 years after the cyclone showed that there was substantial recovery in the protected creek forest but changes in sedimentation prevented recovery in the seaward sites that are exposed to storm surges and wind. This study highlighted the necessity for field based investigations in addition to remote sensing as results showed site specific differences. The percentage of living trees at the creek forest ranged from 71 to 97% from the outer to inner forest. Also species density was higher at the creek sites from the outer (101 ± 63 tree/ha) to inner forest (488 ± 111 trees/ha) as was the complexity index (0.09 to 0.25 respectively). At the seaward forest the percentage of living trees increased from 0 to 79% from the outer to inner forest. Seedlings (up to 40 cm height) dominated the understory throughout the forest however the outer edge of the seaward forest had no regeneration at all. This forest recovered naturally from the cyclone, however it is important to maintain low exploitation levels to ensure forest resilience in case of similar future impacts. The frequency and intensity of cyclones is expected to increase with climate change and thus the results can contribute to management strategies and climate change adaptation plans. 3 Human impacts were investigated at a peri-urban, rural and island setting in Cabo Delgado province. It was hypothesized that peri-urban forests would be more impacted. However an analysis of LandSat images showed that mangrove cover at the peri-urban site actually increased by 22.7% between 1991 and 2013; while rural forests lost 23.2% of its area during the same period. Field studies showed that there was no significant difference between average tree density for the different sites (p= 0.16) and the low complexity indices indicated young disturbed forests. At the peri-urban and rural sites, the tree diameter class 5.1-8 cm was targeted for extraction, while at the rural island all size classes were targeted. The proportion of stump:living trees was 1:11 at the peri-urban site; 1:9 at the rural site and 1:4 at the rural island. Most of the standing trees were crooked and not suitable for building purposes. The small extractive use of mangroves at the peri-urban site could be related to the fact that the dominant ethnic group has kept its essentially agricultural habits while at the rural site the people are typically fishermen and marine invertebrate collectors that rely on mangroves and marine resources for their livelihoods. Proposed management measures for these sites include raising awareness at all sites and conducting mangrove restoration at the peri-urban (abandoned saltpans and aquaculture farm) and rural sites. A community-based management system at Nhangau (Sofala province) was analysed in order to assess how this has achieved management conservation objectives. After facing several impacts due to mangrove degradation, the community of Nhangau engaged in mangrove replanting and management. The main management actions were (1) reduction of extractive uses, (2) continuous awareness and mangrove planting and (3) law enforcement. The restoration interventions started in the late 1990s by the local government in partnership with the local community and NGOs. Currently (2018), most of the activities are led by the local Natural Resources Management Committee (NRMC). Ten hectares of mangrove were planted between 1996 and 2017, and according to the local community the restored areas are already providing important ecological services such as temperature regulation. There are several challenges such as, limited functionality of the NRMC and its interaction with other stakeholders, Government representatives and local NGOs. There is also a lack of alternative livelihoods for mangrove cutters and the wider Nhangau community. Improvements to the system include better integration of local government representative structures with the civil society organizations (NGO and NRMC), law enforcement, financing of the appropriate sustainable use practices, environmental awareness and education and the promotion of appropriate NRMC functionality and representation. With these improvements this community-based management system can be effective as a management tool to meet mangrove conservation objectives and serve as a replicable model for other parts of the country. In conclusion, this research has documented both anthropogenic and climate-related impacts on mangroves in Mozambique and highlighted options for mangrove management focusing at strengthening the community –based management of mangroves in rural sites. Mangrove management would improve significantly by strengthening the legislation on specific mangrove issues combined with law enforcement and better community organization and their training and sensitization to manage mangrove resources at the local level. Such actions will increase the resilience of forests, allowing sustainable use and faster recovery in case of impacts by either anthropogenic or natural factors such as cyclones.
