- 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.

- Description: This Research Report that this research was motivated by the fact that despite thetremendous achievements have been realized from the successful implementation ofgovernment programmes and projects related the construction and refurbishment of medical facilities, educational, bridges and road infrastructure facilities. 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: 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 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: 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.

- 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 false codling moth (FCM), Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae), is an important pest of citrus in South Africa and challenging to manage due to its inconspicuous nature. An effective method currently being employed for the area-wide suppression of the FCM is the Sterile Insect Technique (SIT) and the effective dispersal of sterile moths is very important for success with SIT. This study was conducted in the Addo area of the Sundays River Valley (Eastern Cape) where the programme is commercially used. In this study, sterile male moths were released in different orchards on a citrus farm, and in nearby veld at different times of the year, and their dispersal was monitored through the use of pheromone traps. Various climatic factors were monitored. This provided insight into the local dispersal of sterile male FCM adults in response to abiotic cues (particularly climatic factors). The movement of the FCM in four citrus cultivars, namely lemons, navel and Valencia oranges and mandarins and in the nearby veld (open field), was determined at six different stages of the year. Results clearly indicated that sterile FCM movement is concentrated within citrus orchards, as very few moths were trapped beyond 30 m from the release point, particularly in navel and Valencia orchards. Of the climatic factors measured, minimum and maximum temperatures had the most significant influence on FCM dispersal, and based on the results, various recommendations are made for the releases of sterile FCM in an area-wide SIT management programmes on citrus. A better understanding of the dispersal capabilities of the FCM in an agricultural system, under different conditions and at different times of the year, is invaluable not only in improving release strategies in an SIT programme but in planning future control strategies against the FCM.

- Description: Driven by the needs of growing populations, industrial and governing powers are successfully accelerating the rate of industrial consumption, production and employment as if the earth’s resources are in unlimited supply. In contrast, a range of international sustainable development forums, inspired by visionary individuals, have made significant progress in creating awareness that the footprint of human activity is exceeding the earth’s sink and source capacity; and educating people in government, workplaces and communities to slow down industrial consumption and clean up production. Turning around conventional and short sighted ‘business as usual’ logic, and directing economies toward greener, long-term sustainability outcomes, still meet with resistance and hidden unsustainable agendas. The ‘green economy’ drive nevertheless since 2008 attracts financial and human resources and bold action in favour of more sustainable management of human-nature relations. The sustainable development movement for example advocates a ‘triple bottom line’ approach, holding that socially and ecologically responsible economic development would be sustainable. The sustainability movement has attained significant buy-in among governments and business communities. It forms the under-labouring philosophy of the programmes reviewed in this case study. The thesis reviews social-economic events paving the way for a global green economy. Taking a leadership role in the sustainable development movement the United Nations (UN) and the Organisation for Economic Co-Operation and Development (OECD) concurred to respond to the 2008 world-wide economic meltdown with a two-pronged ‘Green New Deal’ (UNEP, 2008). The Green New Deal financial package helps restore multi-national economic growth, employment and markets while re-shaping economies to follow an ecologically and socially responsible growth trajectory. South Africa implements green economy principles as part of the 2010 The New Growth Path overarching policy framework, with an implementation strategy embedded in the 2011 National Development Plan (NDP) (RSA. The Presidency, 2010; 2011). The New Growth Path emphasises that the transformation of South Africa’s un-sustainable economic and educational legacy to a more sustainable future is not expected to follow a smooth, linear process. The transition to a green economy is rather expected to be an event of “… noisy, healthy democracy” (RSA. The Presidency, 2010). A green, low carbon economy particularly constitutes a pledge to slow down and turn the human induced climate change trajectory around. McKinsey (2009) argues that this pledge is attainable on a world-wide scale, as sufficient and suitable environmentally sound techniques and technologies are already in place. Attaining buy-in from business stakeholders toward re-thinking and amending an economy’s self-defying large environmental footprint (inclusive of carbon, water and waste footprints) however requires education starting with awarenessraising followed by educational programmes and official curricula aimed at implementation and continuous improvement of green practices in day to day ‘doings and beings’ (Sen, 1997). This study at implementation level reviews two green economy training programmes and their emergence in South Africa around this rationale. The awareness generation and training programmes elected as case study examples are the ‘Resource Efficient and Cleaner Production’ (RECP) and ‘Industrial Energy Efficiency’ (IEE) programmes, of the hosting agency National Cleaner Production Centre of South Africa (NCPC-SA). The RECP and IEE teams reach out to decision makers, engineers and artisans at industrial workplaces and workplace related events to add green competences to their business-as-usual skill sets. Implementing green options in industry typically slows down industrial scale resource consumption, pollution, waste generation and green-house gas (GHG) emissions while optimising resource productivity and enterprise excellence. Optimised supply side systems allow industry to reduce energy and material intensity of products thus reducing cost and producing more with less. In transitioning to a ‘Green GDP’ economy South Africa is awakening to the reality that natural resources constitute the original, albeit limited feedstock for growth and employment.

- Description: Driven by the needs of growing populations, industrial and governing powers are successfully accelerating the rate of industrial consumption, production and employment as if the earth’s resources are in unlimited supply. In contrast, a range of international sustainable development forums, inspired by visionary individuals, have made significant progress in creating awareness that the footprint of human activity is exceeding the earth’s sink and source capacity; and educating people in government, workplaces and communities to slow down industrial consumption and clean up production. Turning around conventional and short sighted ‘business as usual’ logic, and directing economies toward greener, long-term sustainability outcomes, still meet with resistance and hidden unsustainable agendas. The ‘green economy’ drive nevertheless since 2008 attracts financial and human resources and bold action in favour of more sustainable management of human-nature relations. The sustainable development movement for example advocates a ‘triple bottom line’ approach, holding that socially and ecologically responsible economic development would be sustainable. The sustainability movement has attained significant buy-in among governments and business communities. It forms the under-labouring philosophy of the programmes reviewed in this case study. The thesis reviews social-economic events paving the way for a global green economy. Taking a leadership role in the sustainable development movement the United Nations (UN) and the Organisation for Economic Co-Operation and Development (OECD) concurred to respond to the 2008 world-wide economic meltdown with a two-pronged ‘Green New Deal’ (UNEP, 2008). The Green New Deal financial package helps restore multi-national economic growth, employment and markets while re-shaping economies to follow an ecologically and socially responsible growth trajectory. South Africa implements green economy principles as part of the 2010 The New Growth Path overarching policy framework, with an implementation strategy embedded in the 2011 National Development Plan (NDP) (RSA. The Presidency, 2010; 2011). The New Growth Path emphasises that the transformation of South Africa’s un-sustainable economic and educational legacy to a more sustainable future is not expected to follow a smooth, linear process. The transition to a green economy is rather expected to be an event of “… noisy, healthy democracy” (RSA. The Presidency, 2010). A green, low carbon economy particularly constitutes a pledge to slow down and turn the human induced climate change trajectory around. McKinsey (2009) argues that this pledge is attainable on a world-wide scale, as sufficient and suitable environmentally sound techniques and technologies are already in place. Attaining buy-in from business stakeholders toward re-thinking and amending an economy’s self-defying large environmental footprint (inclusive of carbon, water and waste footprints) however requires education starting with awarenessraising followed by educational programmes and official curricula aimed at implementation and continuous improvement of green practices in day to day ‘doings and beings’ (Sen, 1997). This study at implementation level reviews two green economy training programmes and their emergence in South Africa around this rationale. The awareness generation and training programmes elected as case study examples are the ‘Resource Efficient and Cleaner Production’ (RECP) and ‘Industrial Energy Efficiency’ (IEE) programmes, of the hosting agency National Cleaner Production Centre of South Africa (NCPC-SA). The RECP and IEE teams reach out to decision makers, engineers and artisans at industrial workplaces and workplace related events to add green competences to their business-as-usual skill sets. Implementing green options in industry typically slows down industrial scale resource consumption, pollution, waste generation and green-house gas (GHG) emissions while optimising resource productivity and enterprise excellence. Optimised supply side systems allow industry to reduce energy and material intensity of products thus reducing cost and producing more with less. In transitioning to a ‘Green GDP’ economy South Africa is awakening to the reality that natural resources constitute the original, albeit limited feedstock for growth and employment. The RECP and IEE approach also contribute to reduction of industrial waste, waste-to-landfill, and energy and resource security. Literature reviewed for this research provides evidence that the green economy’s triple bottom line philosophy is quantifiable thus manageable. A range of green economy management tools are emerging, including guidelines for carbon, water and environmental footprinting and the green-house gas abatement cost curve (see section 2.2.5) (McKinsey and Company, 2009). Transitioning from business as usual to ecologically sustainable industrial sectors however requires visionary, educated leadership, willing and capable of introducing modern and more efficient techniques and technologies.

- Description: Organisations worldwide are attempting to identify talent by using various assessment methods to evaluate competencies perceived to be core to the mandate of their organisations. In recent years recruitment and selection of individuals rely on assessment methods deemed to have high validity and reliability. One such assessment method used worldwide to evaluate top management is the assessment centre, commonly referred to as the AC. The main research problem of this study focussed on an evaluation of the extent to which the assessment centre method is effectively used for the selection and development of senior management employees in the public service of Botswana. The main research problem had eight sub-problems which were addressed through the following actions: A comprehensive literature study was conducted to define and establish the purpose of assessment centres. Moreover, the study aimed to establish the international best practice for the administration of the assessment centre as a tool for selection and talent development. Subsequent to the literature study an interview schedule and survey questionnaire were developed based on the literature. The interview schedule was used to obtain information from consultants who provide assessment centre services to the public service. The objective of the questionnaire was to obtain information from the recipients of the service and determine the extent to which that information compares with information obtained from the consultants. The questionnaire was distributed to a randomly selected population. The results of the empirical study were statistically analysed and interpreted and revealed that permanent and deputy permanent secretaries are more aware of the reasons for using the assessment centre method than directors and deputy directors. These senior management employees felt that the assessment centre is an effective tool for selection and development but the results from the assessment centre are not optimally used for development. The study revealed that generally the assessment centre process conducted in the Botswana public service is in line with international best practice of assessment centres. However, there are certain areas that need some improvement for the assessment centre to entirely conform to international best practice. These areas include the implementation of an assessment centre policy and the improvement of feedback and vital information provided to participants prior to the centre. The empirical study also revealed that senior management employees hold the view that many senior officers in the public service do not know the importance of the assessment centre method and are not comfortable to participate in such a centre. The assessment centre method has proven to be an effective tool for evaluating competencies. This is due to its use of multiple techniques, assessors, simulations and exercises. Theory has revealed that the assessment centre has higher validity and reliability than other assessment methods. However, due to the high costs of running assessment centres, some organisations take shortcuts and therefore jeopardise its validity.

- Description: The study focussed on the effectiveness of control measures for dealing with absenteeism of educators with specific reference to selected schools at Libode District in the Province of the Eastern Cape. It identified the policy framework including rules and regulations relating to the absenteeism of educators. It assessed the effectiveness of control measures which are currently at the disposal of the selected schools and it also investigated the challenges faced by school principals in addressing the challenge of absenteeism of educators in the selected schools. A qualitative research methodology was used in undertaking the study. Purposive sampling was used to select the schools and participants for the study. Participants were comprised of school principals and Education Development Officers. Data was collected through structured and semi-structured interviews. Literature study showed that the management of educator absenteeism is an important aspect of Human Resource Management in schools. Furthermore, the study found that control measures for dealing with absenteeism are not properly applied in many schools and there is no consistency in the manner in which they are utilised by school principals. The study also found that school principals are struggling to manage absenteeism to the extent that some of them are not sure how to deal with educators who abuse leave. The study recommends that school principals should be empowered on leave management through various forms of training which include workshops.

- Description: South Africa is a democratic country since 1994 and transformation brought policies that aimed to address the inequalities and poverty situation countrywide. During apartheid era the existence of social assistance was more focused on minority group. Hence the eroded social inequality cannot be ignored as poverty takes its toll in our communities. It was the previously termed state maintenance grant that was phased out with the introduction of Child support grant (CSG). The purpose of CSG was to reduce child poverty; however a long list of challenges regarding the aims and objectives of the CSG surfaced. This study was about the challenges of child support grant as poverty alleviation strategy in waNobuhle community in Uitenhage. The purpose of the study was also to investigate the value CSG adds in the beneficiaries’ lives in terms of poverty alleviation and what is mostly hindering the CSG from alleviating poverty. The research design for the study could be classified as mixed designs which include qualitative and quantitative approach, taking a form of action research. A sample of 30 participants was drawn from SASSA beneficiaries. The sampling method for the study was purposive, which is a non-probability sampling. Semi structured questionnaires and semi structured interviews were utilized to collect data and the data collected was analysed thematically and descriptive statistics analysis was undertaken as well. Questionnaires to collect data from the thirty (30) CSG beneficiaries’ from KwaNobuhle community and semi structured interviews was undertaken. The most important findings that emerged from the study were that participants appeared to have a clear understanding of the fact that CSG represented a government strategy to support children, fight poverty and uplift the standard of living for the poor. However, majority of the participants were not satisfied with CSG as poverty alleviation strategy, participant’s wants government to increase the amount of CSG and to create employment opportunities. The CSG was pointed as inadequate due to the fact that all family members of the beneficiaries are dependent on the CSG. The conclusion drawn was that CSG paid to KwaNobuhle beneficiaries seemed to be achieving their aims even though the CSG is announced to be inadequate, employment is a necessity and the gap between departments serving the community. The findings of the study are discussed as suggestions to SASSA and the Department of Social development.

- Description: This study seeks to investigate the underlying ideologies and practices behind the perception that women who are in command positions are unable to command and control, especially those who are in the operational environment. The study was executed in the Eastern Cape Province (Eastern Cape), in Buffalo City Metropolitan Municipality (BCM). The research participants (respondents) were constituted by 33 police officers from diverse police stations within the BCM. The participants were divided according to gender, i.e. 24 females and 9 males. With regards to objectives of the study, the aim was to investigate the following issues: i) to understand factors that make women not to be accepted in their positions as SAPS' operational commanders, by their male subordinateslcolleagues and community members. ii) To understand factors that make women not to be accepted in their positions as SAPS' operational commanders, by their male subordinates/colleagues and community members, and iii) to explore strategies to utilize in making SAPS' women operational commanders, survive while managing their day-te-day respective units/components effectively and efficiently. Regarding research design, this study mainly used a qualitative research method combined with a bit of a quantitative approach. And then the data collection method involved making use of semi structured interviews to all the respondents. The results of this study show that there is still a huge difference in the number of women who are commanders compared to their male counterparts, especially in those environments that were previously regarded as male dominated. Further, despite the necessary training being provided by the SAPS to women officers, the necessary support in particular from management is still a challenge. Lastly, the argument of this study is that there is still not a fair representation of women in command positions within the SAPS, especially, in the previously male dominated environments.
