- Description: “Academic freedom” does not mean the same thing to everyone. There are, to be sure, a few who argue against it. Sandra Korn, in the Harvard Crimson last year, argued that we should abandon academic freedom in favor of academic justice. She argues that we have reached a consensus on issues such as racism, classism and sexism, and so to promote racist or classist or sexist views under the guise of “academic freedom” is to ignore a higher standard and more importantly to ignore the fact that academic freedom is always couched in political realities, and is never the dispassionate exercise of reason and the pursuit of knowledge. It always serves an agenda, and so if that is the case, it should serve the agenda of justice, particularly justice for disadvantaged and marginalized people. Her online article, when I last looked, had almost 1300 comments, and had inspired commentary from a number of other publications. You can imagine the range of these comments and reactions: everything from “this is long overdue” to the newest favorite insult circulating the internet, “she’s just another Social Justice Warrior (SJW).”

- Description: In this dissertation, the socio-ecological transformations that occurred during Cuba’s Revolución Agrícola are explored, against the backdrop of the historical subalternisation of the country as a consequence of Spanish and American imperialism, and in relation to the continuing subalternisation of the country and its people through the neoliberal mass media. To contextualize such exploration, the origins of large-scale privatization of common land, and the subsequent process of urbanization in the West, are investigated, before Cuba’s similar developmental path – as a result of Spanish colonialism, U.S. imperialism, and communist influence – is detailed. Thereafter, the way in which Cuba established an alternative food paradigm, characterised by local, communal, and urban production during the country’s ‘Special Period’ in the 1990s, is discussed, with a view to illustrating how this eco-socialist model of food production, in both rural and urban areas, led to new relations between people and nature. This Cuban model is then posited as a socio-ecologically sustainable model of food production, deserving of the attention of communities around the world, who seek to gain a degree of autonomy from neoliberal agribusiness. Conversely, the efforts of mainstream neoliberal mass media to silence the immensely positive characteristics of the revolution are also investigated, and framed in terms of the historical subjugation of Cuban voices in the American mass media, and the contemporary marginalisation of the country and its people in the neoliberal mass media. Finally, the dissertation concludes by examining the alternative media response, on the part of several prominent Cubans and those sympathetic to their cause, to bring attention to the value of the socio-ecological transformations that have occurred on the island, against the backdrop of various theorisations of the importance of alternative media platforms as a radical counterforce to neoliberal mass media hegemony.

Trends indicate that only iota of evidence implies that the concept of risk management is fully integrated and embraced as part of a culture for ensuring the successful project implementation by the Modern South African public sector organizations. Empirical research revealed that the common types of risks that have been affecting the successful implementation of government projects and programmes include: riots, fraud, corruption, changes in demographic figures, outsourcing risks, and floods and changes in weather. Most of the participants stated that risks associated with riots do not only arise from the riots within the government departments, but also in the external environment. In terms of the internal riots, they revealed that when the employees go on strike or riots on their own or in solidarity with the other trade unions, leading to the process for the implementation of government projects and programmes being affected. Yet, in certain cases, they noted that internal riots or strikes most occur as preceded by rumours that the riots by a particular union will take place and may significantly affect the ongoing process of implementation of government programmes. Besides risks associated with the internal riots by the employees and the communities, the interview findings also indicated that the other forms of risks arise from the strikes and riots by the private enterprises.

- Description: Growth in information and communication technology (ICT) is drastically changing the way businesses, especially in the service industries, are conducted. The financial services industry and banking in particular, is not excluded from this technology explosion. Internet banking, even though not new in advanced countries, is a new transaction channel being used by banks in some parts of Africa, especially Ghana, to offer various products and services to their customers. However, this medium has not been fully exploited by these banks as there are many hurdles the banks must triumph over. In deploying this technology and these systems, there are several factors which banks must take into consideration before fully deploying such a system to their customers, hence the motivation for this study. The absence of suitable and sufficient knowledge on this topic also exposes a “rhetoric versus reality” argument of whether the intention to adopt Internet banking is critical to the strategies and ultimate success of banks in Ghana. For banks to stay ahead of competition as well as to attract and maintain their clientele, it is of paramount importance to gather and link the perspectives of both clients and bank managers in order for banks to ensure that they perform according to the needs and expectations of their clients. In order to achieve the intended results, an empirical study was conducted by taking into consideration the viewpoints of both bank clients and bank managers in determining the factors that customers take into consideration before adopting the Internet banking medium. The primary aim of this study was to quantify significant relationships between the selected variables. Therefore the positivism research paradigm was used, while the phenomenological paradigm was employed for the measuring instruments. Because multiple sources of data were used, from the perspectives of banking clients and managers in Ghana, methodological triangulation was adopted for this study. The results of the empirical investigation showed that both groups (clients and managers) considered the variables of market share, technology acceptance, diffusion of innovation, organisational variables, organisational efficiency, and business strategy to have direct influence on the adoption of Internet banking. However, they differed in opinion concerning the degree of influence of these variables. The bank managers’ responses leaned more towards strong agreement with the importance of these variables than did those of the bank clients. Thus, for bank clients to readily adopt the Internet banking medium for their banking transactions, bank managers must take a closer look at these determinant factors described in the study. The study showed that the population group, educational and income levels exerted an influence on the perceptions clients have regarding Internet banking adoption factors. It was found that the higher the education and income levels of the clients, the easier it was for them to adopt Internet banking. Also, the male group dominated the use of the Internet banking. This is supported by the fact that there is a growing middle class in Ghana that falls within this category of banking clients.

- Description: The shoulder is a complex anatomical structure and imaging plays an important role in the diagnosis and management of shoulder conditions. The complexity of the shoulder’s anatomy has led to the development of multiple radiographic projections and techniques within plain film imaging with each projection intended to demonstrate specific aspects of the anatomy of the shoulder. However, reproducing the required projections can be difficult especially if radiographers are not familiar with the projections and their evaluation criteria. Literature has revealed the importance of a comprehensive knowledge and understanding of anatomy, patient positioning, beam direction and centring point, and evaluation criteria to ensure a quality projection for accurate diagnoses. The aim of the study was to determine the knowledge and understanding of radiographers with regard to the supraspinatus outlet projection (SOP) for shoulder impingement syndrome (SIS) and its evaluation criteria. The inferences derived from the research findings were used to develop guidelines for a structured in-service training programme for practising radiographers to optimise their knowledge and understanding of the supraspinatus outlet projection in shoulder impingement syndrome. The proposed study followed a quantitative approach. Furthermore, a descriptive, exploratory, contextual design was employed. The research population consisted of practising radiographers working in the public and private hospitals of the Nelson Mandela Bay Municipality. The data were collected by means of a structured self-administered questionnaire. The questionnaire comprised of three sections. The first section requested demographic information from the participants. The second section assessed their knowledge and understanding regarding the scapular ‘Y’ and the supraspinatus outlet projections and shoulder impingement syndrome. The third section assessed their knowledge and understanding of anatomy and image evaluation/critiquing. The reliability and validity of the data collection instrument was ensured by conducting a pilot study and comparing the results with those of the main study. In addition, the expertise and guidance of a radiographer experienced in the clinical training of radiographers, the supervisor (who has twenty years’ experience in the teaching of radiographers) and a statistician was obtained. Descriptive and inferential statistical analyses were performed by means of a statistical programme and with the guidance of a statistician. The researcher ensured that the study was conducted in an ethical manner by adhering to the ethical principles of beneficence, justice and respect for persons.

- Description: Previous research has established a relationship between exercise and cognition, with more emphasis on this ascertained link, being made on the effects of long term and endurance exercise on cognition. However, enhanced worker effectiveness relies on a strong acute collaboration of physical and cognitive performance during task execution. As a result, the purpose of this study was to examine the acute effects of extended aerobic exercise on visual perception, working memory and motor responses, and to achieve this 24 participants (12 males and 12 females) aged between 18 and 24 participated in a 2 bout cycling exercise. The experimental condition had cycling resistance set at 60 percent of each individual’s maximum aerobic output and the control condition had zero cycling resistance, where three cognitive tasks were performed at 10 minute intervals during the cycling exercise. The results showed that exercise did not affect any significant changes on the cognitive performance measures over the entire cycling duration, as well as during the exercise phase (cycling with resistance). However, visual perception improved significantly (p<0.05) immediately after exercise. This led to the conclusion that moderate to high intensity exercise when performed for an extended duration, has selective effects on certain cognitive performance measures, with the time at which the performance is measured during the exercise being a relevant factor to be considered for maximum activation effects of the exercise.

- Description: Collective bargaining is the process whereby employees act as a collective unit whilst negotiating terms and conditions of employment with employers. The collective unit typically takes the form of a trade union, mandated by its members to negotiate on their behalf. By negotiating collectively the inherent imbalance of power between employer and individual employee is seen to be neutralised. The process of collective bargaining enjoys legal status in South Africa and around the world. The Industrial Conciliation Act of 1924 institutionalised collective bargaining for the first time in the form of the Industrial-Council system. This sectoral bargaining system stood firm throughout the pre-democracy period but initially excluded non-white employees. Industrial unrest in the 1970s was the catalyst for the Wiehan commission which ultimately brought all employees into the fold. By the dawn of democracy in South Africa the bargaining system enjoyed wide-spread support and legitimacy. This was particularly so amongst the COSATU-led labour movement which enjoyed a position of political strength. This support and strength were reflected in the contents of both the Labour Relations Act and the Constitution which enshrined the constitutional right to engage in collective bargaining. Possibly the most debated aspect of the Council system has been the question of extending agreements to non-parties. Those in favour argue that the Council system cannot function in the absence of extensions. This is so because what would then effectively be a voluntary system would not attract sufficient volunteers. Those against argue that extensions act as a barrier to economic activity, particularly for small and new businesses. Legislation has, since 1924, facilitated the extension of agreements as long as certain criteria are met. Section 32 of the Labour Relations Act is the current extension vehicle. The extension criteria have vacillated over time and especially so in recent history with section 32 being subject to change in every post-democracy amendment to the Act. Possibly the most serious challenge to the extension status quo has come in the form of a constitutional challenge by the Free-Market Foundation. The Foundation advances old economic arguments but links these to an alleged impingement of constitutional rights. The challenge comes at a time when the country is experiencing the most significant socio-political turbulence since democracy. This includes the most enduring strike in our history, a landmark-employer lock-out and a parliamentary facelift. The Metal and Engineering Industries Bargaining Council oversees the biggest manufacturing sector in the South African economy. This status prompted the Council to submit its own responding papers in the Free-Market case. Particularly fascinating is that an employer party to the Council not only supports the Foundation case but has also lodged its own proceedings against the extension of the 2014 Engineering agreement. Both these cases are still pending and the outcomes have the potential to transform the political and economic landscape of our country.

- Description: This study is situated within the context of the emerging South African Biodiversity Sector and focuses on the supply of and demand for scarce skilled biodiversity professionals. It does so through investigating the transition a young biodiversity professional makes from a higher education institution to the workplace by drawing attention to the factors encountered or perceived to be encountered during this development. The study forms part of a research programme established between Rhodes University, GreenMatter and the Culture Arts Tourism Hospitality Sport Education and Training Authority (CATHSSETA), which seeks to contribute to the body of knowledge pertaining to "green" skills development and retention within the South African biodiversity sector. It is a qualitative study, comprising nested case studies within two larger case studies of scarce skills – those of wildlife veterinarians and freshwater ecologists – as identified by the biodiversity priority scarce skills list (SANBI & Lewis Foundation, 2012). The study is supported by Bronfenbrenner's (1979) Ecological Systems theory and underpinned by the principles of basic critical realism and emergence (Archer, Bhaskar, Collier, Lawson, & Norrie, 1998). Data was generated through a range of data collection methods, including semi-structured interviews, participant observation and document analysis. The aim of these methods was to enable a greater understanding of the factors influencing transitioning and the unique transitions of selected individuals. Findings revealed that the transitions of the participants, although unique to each of them, included the following commonalities: exposure to biodiversity at an early stage in an individual's life paved the way for the development and nurturing of an interest or passion in biodiversity; experience gained prior to entry into the workplace is a powerful enabling factor; the presence or absence of a mentor can be pivotal in the transition of an individual; the gap in knowledge pertaining to demand side or workplace information is a large constraining factor; workplace dynamics affect the demand for, and eventual supply of, biodiversity professionals; the presence of human capital development strategies and structures is beneficial to the individual's transition, and the overall ecosystemic development of an individual has an effect on the supply of specific scarce-skilled individuals to the workforce. This study demonstrates that through the employment of nested case studies, similar research focussing on other scarce skills within the biodiversity sector, as per the GreenMatter Priority Skills List of 2012, can be produced, which would help to address the knowledge gaps pertaining to scarce skills, as indicated by the Biodiversity Human Capital Development Strategy (2010).

- Description: The purpose of the study was to investigate the educators’ perceptions on the role of the South African Democratic Teachers’ Union (SADTU) in teacher professional development. The study also investigated the Union’s perceived challenges in contributing to teacher professionalism in South Africa, their perceived professional priorities and perceived expectations of teachers. The research genre used for this study was the interpretivism or constructivism paradigm. The qualitative methodology was used and case study employed as the research design of the study. The findings of this study were that SADTU were perceived as militant activists. Their activities were perceived as often very disruptive to education and their role appeared to be more politically focused than educational. They promoted and protected teacher labour rights and interests. However, they had no programme, nor the expertise nor the resources to respond to teachers’ professional development needs. The perceptions about them were that they had minimal or negligible contribution to teacher professional development. SADTU conducted training, but with nothing of value to teacher professional development. The unethical, unconstitutional and professionally non-developmental cadre deployment of SADTU leadership compromised the Union. Another finding was the important role of appropriate continuous professional development programmes in the improvement of the teachers’ own professional development, in the improvement of classroom practices and eventual enhanced learner performance. Inclusive to professional development are educationally good skills and values to colleagues, learners and parents both at school and out of school. Recommendations for SADTU were the: development of a clear programme on Teacher Professional Development; mobilisation of SADTU members towards restoring and enhancing the dignity of the teaching profession; engaging politically in curriculum policymaking to form inclusive professional associations; ending cadre deployment for senior management posts by SADTU leadership; establish development centres for critical maths and science, computers skills and other subjects and resuscitation of teacher colleges.

- Description: This study sought to empirically investigate the existence of calendar effects and market anomalies on the JSE using monthly and daily closing prices of the ALSI, Top 40, Mid Cap and Small Cap index; as well as, daily closing prices on the Value, Growth and Dividend Plus index during the sample period 2002 – 2013. The anomalies analysed are the January effect, the weekend effect, the size effect, the value effect, and the dividend yield effect. The empirical analysis uses a number of MSAR with a different number of regimes and lag orders. The results from the investigation of the January effect show the non-existence of the January effect and the value effect on the JSE during the periods 2002 – 2013 and 2004 – 2013, respectively. However, the weekend effect was found significant in the Mid Cap and the Small Cap index, and the size effect was also found significant during the same period 2002 - 2013. Finally the results from a Granger causality test concluded that there is a relationship between the returns on the Dividend Plus index and the ALSI, effectively proving the existence of the dividend yield effect on the JSE between 2006 and 2013. Additionally, the anomalies found imply the opportunity for investors to make returns above buy-and-hold.

- Description: This research deals with achieving and maintaining price stability in Sub-Saharan Africa (SSA) through the practice of monetary-policy transparency (MPT). On the one hand, MPT refers to a monetary strategy whereby the central bank is insulated from political influence and made accountable to society through disclosure of its policies, procedures, economic models, data and forecasts, operations and political practices (such as objectives, personnel independence, and the like). On the other hand, price stability refers to achieving and maintaining low and stable levels of inflation conducive for long-term planning and poverty alleviation. The primary objective of this research was to investigate MPT in SSA as it represents a powerful means whereby economic agents’ expectations may be coordinated and managed by the central bank to achieve its societal, objective function of low inflation. The empirical evidence shows that, first, a dependent central bank is more likely to slip into hyperinflation. Second, a SADC (2008) model central bank law is not independent enough to be used as a benchmark for any central bank or as a charter for a regional central bank. Third, the degree of central bank independence in SSA is relatively lower than that in industrialised economies. Fourth, the determinants of MPT in SSA are trade openness, and financial depth that are important factors influencing policy-makers to adopt monetary-policy transparency. Fifth, MPT is associated with a decline in the inflation rate. Sixth, MPT had no significant effect on economic output, whilst trade openness was positively associated with real GDP.

- Description: It is becoming increasingly evident that agriculture is playing a pivotal role in the socio-economic development of South Africa. The agricultural sector is important because it contributes approximately 2% to the gross domestic product of the country. However, many factors impact on the sustainability of traditional agriculture in South Africa. Unpredictable climatic conditions, land degradation and a lack of information and awareness of innovative farming solutions are among the factors plaguing the South African agricultural landscape. Various farming techniques have been looked at in order to mitigate these challenges. Among these interventions are the introduction of organic agriculture, greenhouse agriculture and hydroponic agriculture, which is the focus area of this study. Hydroponic agriculture is a method of precision agriculture where plants are grown in a mineral nutrient solution instead labour- intensive activity that requires an incessant monitoring of the farm environment in order to ensure a successful harvest. Hydroponic agriculture, however, presents a number of challenges that can be mitigated by leveraging the recent mobile Information and Communication Technologies (ICTs) breakthroughs. This dissertation reports on the development of a wireless ICT monitoring application for hydroponic agriculture: HydroWatcher mobile app. HydroWatcher is a complex system that is composed of several interlacing parts and this study will be focusing on the development of the mobile app, the front-end of the system. This focus is motivated by the fact that in such systems the front-end, being the part that the users interact with, is critical for the acceptance of the system. However, in order to design and develop any part of HydroWatcher, it is crucial to understand the context of hydroponic agriculture in South Africa. Therefore, complementary objectives of this study are to identify the critical factors that impact hydroponic agriculture as well as the challenges faced by hydroponic farmers in South Africa. Thus, it leads to the elicitation of the requirements for the design and development of HydroWatcher. This study followed a mixed methods approach, including interviews, observations, exploration of hydroponic farming, to collect the data, which will best enable the researcher to understand the activities relating to hydroponic agriculture. A qualitative content analysis was followed to analyse the data and to constitute the requirements for the system and later to assert their applicability to the mobile app. HydroWatcher proposes to couple recent advances in mobile technology development, like the Android platform, with the contemporary advances in electronics necessary for the creation of wireless sensor nodes, as well as Human Computer interaction guidelines tailored for developing countries, in order to boost the user experience.

- Description: The world has seen unparalleled pressure put on the public sector to improve the speed and quality of service delivery, whilst simultaneously employing measures to cut the costs. South Africa and the Eastern Cape have not been immune to this as there have been complaints and demonstrations from various national and provincial stakeholders demanding more and improved services. The Department of Economic Development, Environmental Affairs and Tourism (DEDEAT) in particular has employed the services of public entities in its quest to realise government’s socio-economic developmental objectives and ease some of the service delivery pressures. These agencies are unfortunately struggling to deliver and the Department is unable to play the oversight role it is legislatively mandated to carry out. The main reason for this seem to be the lack of the capacity to objectively track and measure the performance of these agencies. As they say “you cannot manage what you cannot measure”. This is despite the fact that there is a shareholders’ compact and many other measures in place to enable performance monitoring. Also, the public sector is known to have inherent and unique performance management challenges like broad and vague objectives which lead to too many measurements, a propensity to focus on the “easy to measure” but often irrelevant indicators at the expense of critical outcomes and a short-term orientation that is usually fuelled by political expediency. Against this background, this study sought to make use of a comprehensive and dynamic performance monitoring framework, namely the Balanced Scorecard (BSC), to explore its potential use in assisting government to monitor the performance of public agencies, in particular the Development Finance Institutions (DFI) in South Africa. The proposed framework helps government to focus on the performance drivers of future value, and what decisions and actions are necessary to achieve critical outcomes. The aim of the study therefore is to develop an adjusted BSC framework to monitor the activities of a public sector agency and thus demonstrate how a BSC framework could be used to monitor a public agency by the government department. The study is evaluative in nature and is divided into three sections. Section one is presented as an Evaluation Report. It sets the scene, discusses briefly the key theoretical concepts, outlines the research methods used and presents the findings followed by a discussion and recommendations. Section two delves into the literature in more detail, providing a more extensive review of the literature that informed the investigation, whilst section three provides a more extensive description of the research methodology employed in the study. To achieve the aims of the study, the research drew from the work of various authors in the field including that of Bigliardi, Dormio and Galati, 2011; Bititci, Garengo, Dörfler, and Nudurupati, 2012; Julyan, 2011; Kaplan and Norton, 1992, 1993, 1996, 2001, 2004 and 2006; Niven, 2003 and 2008 and Northcott and Taulapapa, 2012. Also, five BSC perspectives - including the programme specific “equity” perspective - were used to develop an interview schedule. These were used to formulate the key performance objectives and indicators, based on the stakeholder’s responses. These respondents have experience within the programme as administrators, beneficiaries and funders. The research employed purposive sampling with semi-structured in-depth interviews and document analysis as primary and secondary instruments for data collection. In essence, five officials from the agency, one from DEDEAT and two co-operatives participated in the research. The results indicate a general appreciation of and gravitation towards outcome based measures, even though the government culture of focusing on outputs is still prevalent. The results of the study indicated that, generally, a government - public agency BSC based performance monitoring framework would have the following features: Customer objectives and programme mission as the main goal and this will provides clarity at all levels on who the customers are and what are their primary requirements. Clear, visible and stringent financial controls as the agency is administering public resources. Few carefully selected processes and systems that have a direct and positive impact on the customer objectives. Deliberate and consistent efforts to promote the participation of designated groups in the economy of the country. Comprehensive indicators on capacity building as “mission based-organisations rely heavily on skills, dedication and alignment of staff”. Overall, the study concludes that the make-up of the BSC is beneficial to the public sector and in monitoring the public sector agencies for the following reasons: It helps the agency to focus on customers and their needs. It forces the agency to engage and communicate strategic intention with both internal and external stakeholders and thus synchronize competing stakeholder needs. It forces the agency to limit the number of indicators and therefore select the few value adding measures that are aligned to customer outcomes. Through its cause and effect relationship, the agency is compelled to align all the resources, activities and processes to the main goal of the entity. All these help to minimize the principal agent problem, as the use of the BSC can bring clarity on strategy and expectations, provided it is supported with regular communication.

Also, five BSC perspectives - including the programme specific “equity” perspective - were used to develop an interview schedule. These were used to formulate the key performance objectives and indicators, based on the stakeholder’s responses. These respondents have experience within the programme as administrators, beneficiaries and funders. The research employed purposive sampling with semi-structured in-depth interviews and document analysis as primary and secondary instruments for data collection. In essence, five officials from the agency, one from DEDEAT and two co-operatives participated in the research. The results indicate a general appreciation of and gravitation towards outcome based measures, even though the government culture of focusing on outputs is still prevalent. The results of the study indicated that, generally, a government - public agency BSC based performance monitoring framework would have the following features: Customer objectives and programme mission as the main goal and this will provides clarity at all levels on who the customers are and what are their primary requirements. Clear, visible and stringent financial controls as the agency is administering public resources. Few carefully selected processes and systems that have a direct and positive impact on the customer objectives. Deliberate and consistent efforts to promote the participation of designated groups in the economy of the country. Comprehensive indicators on capacity building as “mission based-organisations rely heavily on skills, dedication and alignment of staff”. Overall, the study concludes that the make-up of the BSC is beneficial to the public sector and in monitoring the public sector agencies for the following reasons: It helps the agency to focus on customers and their needs. It forces the agency to engage and communicate strategic intention with both internal and external stakeholders and thus synchronize competing stakeholder needs. It forces the agency to limit the number of indicators and therefore select the few value adding measures that are aligned to customer outcomes. Through its cause and effect relationship, the agency is compelled to align all the resources, activities and processes to the main goal of the entity. All these help to minimize the principal agent problem, as the use of the BSC can bring clarity on strategy and expectations, provided it is supported with regular communication.

- Description: Software based routing simulators suffer from large simulation host requirements and are prone to slow downs because of resource limitations, as well as context switching due to user space to kernel space requests. Furthermore, hardware based simulations do not scale with the passing of time as their available resources are set at the time of manufacture. This research aims to provide a software based, scalable solution to network simulation. It aims to achieve this by a Linux kernel-based solution, through insertion of a custom kernel module. This will reduce the number of context switches by eliminating the user space context requirement, and serve to be highly compatible with any host that can run the Linux kernel. Through careful consideration in data structure choice and software component design, this routing simulator achieved results of over 7 Gbps of throughput over multiple simulated node hops on consumer hardware. Alongside this throughput, this routing simulator also brings to light scalability and the ability to instantiate and simulate networks in excess of 1 million routing nodes within 1 GB of system memory

- Description: The inadequacies of the current generation of deconvolution algorithms are rapidly becoming apparent as new, more sensitive radio interferometers are constructed. In light of these inadequacies, there is renewed interest in the field of deconvolution. Many new algorithms are being developed using the mathematical framework of compressed sensing. One such technique, MORESANE, has recently been shown to be a powerful tool for the recovery of faint difuse emission from synthetic and simulated data. However, the original implementation is not well-suited to large problem sizes due to its computational complexity. Additionally, its use of proprietary software prevents it from being freely distributed and used. This has motivated the development of a freely available Python implementation, PyMORESANE. This thesis describes the implementation of PyMORESANE as well as its subsequent augmentation with MPU and GPGPU code. These additions accelerate the algorithm and thus make it competitive with its legacy counterparts. The acceleration of the algorithm is verified by means of benchmarking tests for varying image size and complexity. Additionally, PyMORESANE is shown to work not only on synthetic data, but on real observational data. This verification means that the MORESANE algorithm, and consequently the PyMORESANE implementation, can be added to the current arsenal of deconvolution tools.

- Description: The purpose of this study was to investigate the factors contributing towards the decline of learners in rural junior secondary schools in the Qumbu Education District in the Eastern Cape, South Africa. This was done because in South Africa before the 1994 elections rural schools were not supported by the apartheid government. Rural areas were disadvantaged in education, in terms of finance. This resulted in poor quality of teaching and learning. Declining numbers of learners in rural schools was occurring in all rural schools. Staffs were alarmed by the declining enrolment of learners in their schools because their schools were affected. Teachers were redeployed to schools where there were sufficient learner numbers. Department of Education due to declining learner numbers in schools introduced rationalisation and re-alignment of schools, meaning closure of some schools with low learner numbers. This led to learners walking long distances to schools. This study was conducted in the Qumbu Education District. It focused on declining numbers of learner enrolment. The literature internationally focused on declining number in enrolment of learners. These learners were afraid of Physical Science (Chemistry side) as a subject. They had taken Chemistry as difficult because of the perceived link with Mathematics. Continentally the literature had alluded to teenage pregnancy, affected and infected learners with HIV/AIDS and human trafficking. In South Africa literature focused on the educational level of parents. Learners with educated parents leave rural schools to study in urban areas because of poor education which is provided in rural areas. Lack of resources in these schools could also be the cause of declining learner numbers in rural junior secondary schools. The study used a quantitative research design to elicit data from the respondents. The respondents in this study were 50 principals of the sampled rural junior secondary schools. Data was collected from 50 participants through the use of a questionnaire; 50 questionnaires were returned and the data which was finally processed was from these 50 questionnaires. The Statistical Package for Social Sciences (SPSS) was used for the analysis of the data. iii The findings of the study revealed that factors such as lack of parental involvement, socio-economic factors, HIV/AIDS - related issues, culture and gender - related issues, lack of resources, teacher and teaching - related issues and the education level of the parents were the contributing factors to the decline in enrolment of learners in rural junior secondary schools in the Qumbu Education District. In the light of the findings, the researcher recommends that more tuition time and the reduction of absenteeism by teachers can help reduce the decline of enrolment in rural junior schools in the Qumbu area. The Department must consider the number of learning areas and not teacher - pupil ratio. The Department should also introduce computer classes, woodwork, bricklaying and other practical skill subjects in these schools. Furthermore there must be resources such as laboratories, libraries and television. Some of the limitations encountered by the researcher during the study included the reluctance of the participants to take part in the research, the inaccessibility of schools in deep rural areas, the slow return rate of completed questionnaires and the obtaining of permission to undertake the study.
