- Description: Wastewater treatment facilities have been identified as potential source of surface water pollution worldwide. In this study, the physicochemical qualities and heavy metal (including Zinc, Cadmium, Iron, Lead and Copper) concentrations in the final effluents, as well as the reduction efficiencies of three municipal wastewater plants in the Eastern Cape, South Africa were evaluated from September 2015 to February 2016 using standard methods. Wastewater effluent and sludge samples were collected from the selected plants on monthly basis over a period of six months from September 2015 to February 2016. Standard analytical method (Atomic absorption spectroscopy [AAS]) was used to assess the concentration levels of heavy metals. The physicochemical parameters assessed include pH, Temperature, Total Dissolved Solid, Turbidity, Biochemical Oxygen Demand, Chemical Oxygen Demand, Alkalinity, Dissolved Oxygen, Free chlorine, Chloride, Sulphate, Phosphate, Ammonium and Electrical Conductivity. The results of the evaluation showed that temperature ranges from 19 to 36 °C, Electrical Conductivity from 60-1095 mS/m, Alkalinity from 2.6-20.9 mg/L, Nitrate from 0.24-26.5 mg/L, Nitrite from 0.01-90 mg/L, Phosphate from 0.02-5.12 mg/L, Ammonium from 0.06-112 mg/L, Sulphate from 3-72 mg/L, Chloride from 3.25-224 mg/L, Chemical Oxygen Demand from 17-394 mg/L and Turbidity from 1.96-715 NTU. Free chlorine concentrations and dissolved oxygen were within the recommended limits for most part of the sampling period and ranged between 0.17-0.48 mg/L and 0.19-21.9 mg/L respectively. The pH, Phosphate, Sulphate and Free chlorine were within acceptable limits while Electrical Conductivity, Temperature, Total Dissolved Solid, Turbidity, Chemical Oxygen Demand, Chloride, Ammonium, Nitrate and Nitrite were not within specified limits. The reduction efficiencies observed generally ranged between 43.9 and 100 percent at all sampling points while zinc and lead were not detected throughout the sampling period. Cadmium showed low reduction rate ranging from 0 to 11.7 percent, while the rate of Copper reduction ranged from 0 to25 percent in January and February 2016. Zinc, lead and cadmium were generally not detected in the sludge samples except in January and February which could be due to the prevailing atmospheric conditions during the sampling period. Cu and Fe were detected through the sampling months of the study. We conclude that these municipal sewage plants are sources of pollution to their receiving watersheds and threats to public and environmental health.

- Description: This treatise explores the potential for destructive conflict between locals and foreign nationals in Summerstrand. In the context of this study, foreign nationals have been defined as people who are from other African countries. This specification was made because it is this particular group that has been victim to violent attacks in South Africa. Those attacks have taken place throughout the country, especially in 2008, in areas that are regarded as ‘townships’ in the South African context. This treatise could be regarded as an unusual product, as it does not explore the dynamics of a township; instead, the focus area is a ‘suburb’. The suburb in question is called ‘Summerstrand’ and it is located in Port Elizabeth. Before the research was conducted, it was assumed that due to the differing dynamics of a suburban area, where people would be wealthier and more educated, the potential of a violent conflict taking place between the two groups (locals and foreign nationals) would be lower. In this treatise, firstly, the topic will be explained more in detail together with an overview of the background to the topic. The background will be discussed in further detail as literature relevant to the field of study will be reviewed and presented in Chapters 2 and 3. The ensuing chapters will elaborate upon how the research has been conducted, after which the findings of the study will be presented to the reader. The last chapter of the treatise offers an analysis of the findings of the study, draws conclusions from the study and offers recommendations in light of the findings of the study.

- Description: This study evaluated the coverage of the 2016 #FeeMustFall students’ protests in Eastern Cape Universities by the Daily Dispatch, which is a daily newspaper published in the Eastern Cape Province. The study employed both quantitative and qualitative research methods. Quantitative data were collected and analyzed through content analysis of the Daily Dispatch Newspaper while the qualitative data collected through focus group discussions among selected students of the University of Fort Hare were analyzed using thematic analysis. The study revealed that 31 stories were published by the Daily Dispatch Newspaper during the period of the protest. The tone of the stories suggested that the Daily Dispatch Newspaper was objective in its reportage. Furthermore, framing analysis of the stories showed that conflict news frame was most prominent in the #FeeMustFall students’ protest stories followed by the attribution of responsibility and human-interest frames. Thematic analysis of the focus group discussions revealed that the type of news frame used for the #FeeMustFall student’s protest stories influenced the thoughts and perceptions of readers as the news frames generated similar audience frames. These findings confirm the views highlighted by the agenda setting and framing theories, which underpin this study. This study indicates that news framing plays a significant role in readers’ perception and as well, defines the way information is presented by readers.

- Description: This thesis is a narrative account of how I have transformed my learning and teaching strategies for Grade 9 learners, generating my own living theory of teaching within a social context with the aim of enabling my learners to construct their own knowledge. My value-embedded practice is reflected in the values I attach to equality, inclusivity, social justice and basic human rights. These embodied values are also a reflection of my commitment to my Christian values which encompass my entire existence and have become the living standards by which I judge the quality of my research. My classroom-based action research methodology is a living transformational process which heralds a change for a more just practice and the inclusion and recognition of the individual. My findings about my learners’ and my own learning offer new conceptualisations about the capacity of my learners to learn in their own unique ways and according to their own potential. I am claiming that the significance of my research is grounded in my ability to demonstrate how I can unleash the untapped potential of learners failing to attain the desired outcomes. I show them how to learn confidently and successfully within a social context using prior knowledge, scaffolding and motivation as teaching and learning tools. This has potential inspiration for new forms of practice and theory in aiming to improve learners’ potential. A significant feature of my account is how my Christian values have been translated into my critical epistemological standards of judgement, and the development of a living theory of practice that enables me to account for educational influences in my learners’ and my own learning.

- Description: This study investigates the types of mathematics teaching aids available at both public and private secondary schools in Windhoek. The study characterises their usage and source as well as teachers’ perceptions towards the use of such teaching resources in the Mathematics classroom. The study is grounded in an interpretive paradigm and employed a mixed methods approach to generate both quantitative and qualitative data in two sequential phases. Phase 1 of the research process, which involved 75 Mathematics teachers, took the form of an audit of the availability and use of teaching aids at 25 secondary schools in Windhoek. A case study methodology was adopted in Phase 2 which focused on five purposively selected schools that displayed different characteristics in terms of the availability of teaching resources. The study found that the majority of teachers at secondary schools in Windhoek have a positive attitude towards the importance and role of teaching aids in Mathematics, seeing them as promoters of hands-on engagement, visual reasoning, active participation and motivation amongst learners. However, in some instances schools are underresourced with respect to certain types of teaching aids, specifically graph boards, geoboards, geometric models and computers. A need for appropriate in-school support on the use of teaching aids was also identified

In any case, there ought to be components to ensure representation against oppressive work rehearses. The Labour Relations Act denoted a noteworthy change in South Africa's statutory modern relations framework. Following the progress to political majority rule government, the LRA embodied the new government's means to remake and democratize the economy and society as connected in the work relations field. Specifically, it presented new organizations went for giving managers and labourers a chance to break with the serious adversarialism that portrayed their relations before. In extending the equitable change, the Labour Relations Act which offered ascend to the foundation of the National Economic Development and Labour Council (NEDLAC) appeared on 18 February 1995, in an offer to add authenticity and straightforwardness to the financial basic leadership process. This research will investigate the law representing fixed term employment in South Africa. It will further give an investigation of the legitimate framework of fixed term representative keeping in mind the end goal to decide if it advances not too bad work in South Africa. This investigation intends to call attention to any substantive and procedural imperfections that might be accessible in the law. The study will likewise be taking the potential lessons which can be gained from different nations with comparative Fixed-term work challenges i.e. Namibia. This implies the examination will survey the current zone of law and propose an alternate approach.

- Description: In 1991 the Treaty enacting the African Economic Community (AEC)1 was signed by the African Heads of State and Government.2 The AEC aims to establish regional free markets that would then be transformed into a continent-wide single market in six subsequent stages enabling the free movement of persons, goods, services, and capital until 2025 at the latest.3 However, to make sure that the free movement of persons in Africa would not also become a "free flow of criminals", the installation of a common market will require intensified police and judicial co-operation, information exchange and external border controls. 1 Treaty Establishing the African Economic Community adopted by the Heads of State and Government of Member States of the Organisation of African Unity in Abuja, Nigeria, 3 June 1991. 2 Art. 6(1) Treaty Establishing the African Economic Community. 3 Arts. 4(2)(h) and 4(2)(i) Treaty Establishing the African Economic Community. Furthermore, the age of globalisation calls into question the traditional concepts of sovereignty. Nowadays individual states are often unable to supervise their complete territory and battle to guard their borders against unwanted goods, people and ideas. Many facets of globalisation - including fast technological development and social and economic interaction - encourage governments to cooperate in order to try to achieve objectives that, acting on their own, they may not believe they can accomplish. Or to express the same thought in its negative sense: to fight unwanted consequences of this development, acting on their own, the states may not be able to achieve. This means that sooner or later the African States will have to address the problem of how to develop a police and judicial regime in criminal matters in order to fight against organised transnational crime. The question therefore is not whether the African States should engage in police and judicial co-operation, but rather what form it should take. The aim of this master treatise is to define the cornerstones of a possible future adoption of a police and judicial regime for the African Union (AU). There are numerous police and judicial co-operations around the world of various types so to make the task more manageable this treaty looks at the European Union (EU) in some detail and uses it as an example or as a guideline to sketch out a possible development of a police and judicial co-operation within the AU. This is for the reason that the EU has succeeded in creating a sophisticated regime of police and judicial co-operation and thus serves as a model of how co-operation levels can be created, handled, and preserved. The EU also serves as an example of how certain obstacles can make co-operation difficult or even prevent efforts for an effective transnational police and judicial co-operation. However, the current EU is the result of the specific circumstances in which its Member States and organs have responded to the economic and political changes they have been faced with. The AU has to operate amidst a political setting and various other circumstances that are very different. As a result the police and judicial co-operation regime of the AU will be very different from the EU model. This treatise argues that due to the vast number of participating states in the AU and the AU's decision-making practice, the continental level is not an appropriate point of departure for the AU to adopt a police and judicial co-operation regime. Police and judicial co-operation within the AU will at first have to be pursued at a sub-regional level. The co-operation should start at the already subdivided Regional Economic Communities (RECs) established by the AEC. Only in time, if at all, will the sub-regional markets be prepared to merge into a continent-wide integration. This is why at the present time the AU will have to accept a mere supervising and stimulating part in pursuing the ultimate objective of developing a police and judicial co-operation on a continent-wide level. Furthermore, this treatise assesses that the huge number of economic, social, and political challenges impair the AU's action ability with the result that it will not be able to establish a supranational legal body comparable to that of the EU in the near future. Also, the African Heads of State and Government are too interested in keeping their sovereign powers to themselves. This is why in Africa integration is more likely to be achieved with an intergovernmental approach. Therefore, police and judicial co-operation should first be exercised by means of informal meetings of the Interior and Justice Ministers and any resulting acts should be classified as (traditional) public international law. This is not to imply that the AU has no role to play here, for said meetings will have to be coordinated and supervised. In order to do justice to its supervising role it is necessary to empower the organs of the AU. This treatise analyses that for the AU to establish an efficient institutional framework, it is extremely important that the Assembly's monopoly over proposing legislation and establishing new organs is changed. Consensus decisions between fifty-four Member States would in an optimal case be replaced by a system where no organ is in total control. Finally, this treatise emphasises the necessity to push ahead with the development of the regional free markets as envisioned by the AEC. Similar to the development in the EU, this will bring about new challenges in combating new types of transnational crimes. This treatise demonstrates that this challenge might bring the necessary momentum to formally introduce police and judicial co-operation in criminal matters, usually a high policy area, on the agenda of the AU. In conclusion, this treatise shows that co-operation in such a sensitive area as security policy first and foremost needs a sufficient amount of trust between the decision makers of the involved states. To develop this necessary trust and the processes building upon this, this treatise argues that a regular meeting between the Interior and Justice Ministers, either inside or outside the framework of the AU, should be launched. Through these meetings the AU could gradually develop a platform for discussion in the area of criminal law and thereby slowly intensify its information exchange and operational co-operation. The history of the EU has shown that the development of a supranational legal system first and foremost requires mutual trust in each other's respective legal systems. Trust is generated by communication in an informal atmosphere. Therefore, this treatise argues that a colloquial intergovernmental co-operation within the field of criminal law is the correct approach for the AU to develop a police and judicial co-operation in criminal matters.

This is for the reason that the EU has succeeded in creating a sophisticated regime of police and judicial co-operation and thus serves as a model of how co-operation levels can be created, handled, and preserved. The EU also serves as an example of how certain obstacles can make co-operation difficult or even prevent efforts for an effective transnational police and judicial co-operation. However, the current EU is the result of the specific circumstances in which its Member States and organs have responded to the economic and political changes they have been faced with. The AU has to operate amidst a political setting and various other circumstances that are very different. As a result the police and judicial co-operation regime of the AU will be very different from the EU model. This treatise argues that due to the vast number of participating states in the AU and the AU's decision-making practice, the continental level is not an appropriate point of departure for the AU to adopt a police and judicial co-operation regime. Police and judicial co-operation within the AU will at first have to be pursued at a sub-regional level. The co-operation should start at the already subdivided Regional Economic Communities (RECs) established by the AEC. Only in time, if at all, will the sub-regional markets be prepared to merge into a continent-wide integration. This is why at the present time the AU will have to accept a mere supervising and stimulating part in pursuing the ultimate objective of developing a police and judicial co-operation on a continent-wide level. Furthermore, this treatise assesses that the huge number of economic, social, and political challenges impair the AU's action ability with the result that it will not be able to establish a supranational legal body comparable to that of the EU in the near future. Also, the African Heads of State and Government are too interested in keeping their sovereign powers to themselves. This is why in Africa integration is more likely to be achieved with an intergovernmental approach. Therefore, police and judicial co-operation should first be exercised by means of informal meetings of the Interior and Justice Ministers and any resulting acts should be classified as (traditional) public international law. This is not to imply that the AU has no role to play here, for said meetings will have to be coordinated and supervised. In order to do justice to its supervising role it is necessary to empower the organs of the AU. This treatise analyses that for the AU to establish an efficient institutional framework, it is extremely important that the Assembly's monopoly over proposing legislation and establishing new organs is changed. Consensus decisions between fifty-four Member States would in an optimal case be replaced by a system where no organ is in total control. Finally, this treatise emphasises the necessity to push ahead with the development of the regional free markets as envisioned by the AEC. Similar to the development in the EU, this will bring about new challenges in combating new types of transnational crimes. This treatise demonstrates that this challenge might bring the necessary momentum to formally introduce police and judicial co-operation in criminal matters, usually a high policy area, on the agenda of the AU. In conclusion, this treatise shows that co-operation in such a sensitive area as security policy first and foremost needs a sufficient amount of trust between the decision makers of the involved states. To develop this necessary trust and the processes building upon this, this treatise argues that a regular meeting between the Interior and Justice Ministers, either inside or outside the framework of the AU, should be launched. Through these meetings the AU could gradually develop a platform for discussion in the area of criminal law and thereby slowly intensify its information exchange and operational co-operation. The history of the EU has shown that the development of a supranational legal system first and foremost requires mutual trust in each other's respective legal systems. Trust is generated by communication in an informal atmosphere. Therefore, this treatise argues that a colloquial intergovernmental co-operation within the field of criminal law is the correct approach for the AU to develop a police and judicial co-operation in criminal matters.

- Description: Internodes 5-8, 10, 13 and 15 of Saccharum sp. var. NCo376 were examined for evidence of symplasmic phloem unloading of sucrose from the phloem, via the bundle sheath to the storage parenchyma. The vascular bundle possesses wellisolated phloem comprised of large diameter sieve elements and small diameter companion cells. A layer of phloem parenchyma surrounds the phloem, except where the phloem abuts the crushed protophloem. Outside this is a sclerenchymatous sheath, directly endarch to a parenchymatous bundle sheath, which is surrounded by storage parenchyma. The bundle sheath is interrupted at the centrifugal pole of the vascular bundle by a phloem fibre cap. Scanning Electron Microscopy revealed plasmodesmal fields throughout the bundle sheath and pith tissue. Transmission Electron Microscopy studies provided evidence of plasmodesmal occlusion, but not in all tissues. Aniline blue reactions under UV light indicate the presence of occluded plasmodesmal fields at the phloem parenchyma / sclerenchymatous sheath interface, and in localised regions of cells which are smaller than the surrounding storage parenchyma cells. This suggests a symplasmic transport pathway at these locations, and, based on these positive aniline blue reactions, with regulation via callose-mediated transplasmodesmal transport. Osmotic stress experiments, which included the addition of Ca2+, did not reveal further callose occlusion in the parenchyma, suggesting that the plasmodesmata in these regions may be closed via a noncallosic mechanism. Dye-coupling studies, using Lucifer Yellow (LYCH), which was iontophoretically injected following turgor-pressure equalisation, showed only rare, limited symplastic transport, usually only between the injected cell and one adjacent cell. Most injections did not result in transport of LYCH, suggesting either a lack of plasmodesmal connectivity, occlusion, or gating of any plasmodesmata present. This limited symplasmic transport, combined with the presence of occluded plasmodesmata at the phloem parenchyma / sclerenchymatous sheath interface suggests the presence of a two-domain phloem-unloading pathway. While symplastic transport may occur from the phloem to the sclerenchymatous sheath, further sucrose transport to the storage parenchyma appears to proceed apoplasmically from the sclerenchymatous sheath / bundle sheath interface, and into storage parenchyma cells across the cell wall and cell membrane via specialised sucrose transporters.

Reproductively it sorts to the guild of nonguarding phytophyllic broodhiders, is a daily, fractional spawner of relatively large, adhesive eggs. The length of the embryonic period varies between 14 and 19 days and the larval period can last for up to 30 days. Sexual maturity can be attained at an age of 150 days from fertilization. The embryology is described in detail and close comparison is made with the embryology of other cyprinodonts to highlight possible phylogenetic differences. Major differences with other cyprinodonts are in the rate of development, and heterochronic shifts in the appearance of certain structures in relation to each other. A discussion is included on the nature of development. It is suggested that development proceeds in a gradual stepwise fashion, interspersed with four major saltations, namely, fertilisation, onset of exogenous feeding, sexual maturity and death

- Description: A considerable number of Very Long Baseline Interferometry (VLBI) surveys have been conducted in the northern hemisphere and very few in the southern hemisphere mostly because of a lack of telescopes and therefore adequate baseline coverage. Thus there is a deficit of calibrator sources in the southern hemisphere. Further, some of the most interesting astronomical objects eg. the galactic centre and the nearest galaxies (the small and large Magellanic Clouds) lie in the southern hemisphere and these require high resolution studies. With a major expansion of radio astronomy observing capability on its way in the southern hemisphere (with the two SKA (Square Kilometre Array) precursors, meerKAT (Karoo Array Telescope) and ASKAP (Australian SKA Pathfinder), leading to the SKA itself) it is clear that interferometry and VLBI in the southern hemisphere need a dense network of calibration sources at different resolutions and a range of frequencies. This work seeks to help redress this problem by presenting an analysis of 31 southern sources to help fill the gaps in the southern hemisphere calibrator distribution. We have developed a multi-parameter method of classifying these sources as calibrators. From our sample of 31 sources, we have 2 class A sources (Excellent calibrators), 16 class B sources (Good calibrators), 9 class C sources (Poor calibrators) and 4 class D sources (Unsuitable calibrators).

The participants were selected on the basis of teaching experience as well as their willingness to share their ideas. An interpretive paradigm was used to collect and analyse data. The data was collected from three participating teachers. These participants were selected from the three secondary schools in the town of Tsumeb in Namibia. I used video recordings of two lessons per teacher as well as semi-structured interviews as my tools to gather data. After the two lessons were video recorded, I conducted a workshop with the teachers to introduce them to the 5 types of mathematical connections pertinent to this study. We analysed the videos together using Businskas' framework as a basis for analysis. This then formed part of the stimulated recall interviews. It was found that, even though teachers were not aware of the concept of mathematical connections before our interactions, there was strong evidence of connections being made and used in their lessons. The two types of connections that were used most frequently (24.1 percent each) were procedural and instruction-oriented connections respectively. Part-whole relationships connections were used the least with a frequency of 12 percent. All three teachers agreed that they needed to make more connections when teaching and that they would think more about connections in future, particularly when preparing their lessons. The study makes recommendations to encourage the continuous use of connections in teaching mathematics.

- Description: Multi-standard classrooms are a distinctive feature of many South African farm schools. This study adopts an ethnographic approach in order to explore how classroom life in one particular Eastern Cape multistandard farm school classroom is shaped by a set of circumstances which influence the nature of teaching and learning in that classroom. The research focuses on the extent to which the difficulties associated with teaching a multi-standard class dictate the teacher's approach to lesson planning and style of teaching and how the resultant pattern of interaction influences language learning within a second language context. Data from a variety of sources, obtained primarily through classroom observations, interviews and questionnaires, is presented. Findings tend to indicate that the demands made on the teachers and pupils in terms of large, multi-standard classes, second language medium of instruction and lack of teaching aids, encourages the use of rote learning techniques which are not conducive to language learning. The pattern of interaction that predominates is a teacher-led series of questions and prompts followed by a chorus response from the pupils. This pattern tends to undermine the communicative aspects of language learning by reducing natural interaction and results in pupil passivity as language learners.

- Description: Old age grant was designed to reduce level of poverty in South Africa and according to SASSA (2016), there are 28 981 beneficiaries of old age grant in Dutywa. The study seeks to investigate the effect of old age grant on poverty eradication programme in Dutywa community in Eastern Cape. Three objectives were set for the study that include: to find out the influence of old age grant on poverty alleviation; to examine the challenges faced by old age grant beneficiaries in fighting poverty; to explore coping mechanisms available for old age grant beneficiaries in fighting poverty; to find out if there are any other support services put in place by professionals or agencies such as Social Workers, Nurses, Educators and Traditional leaders in fighting poverty. Both quantitative and qualitative approaches were used to collect data from respondents. A sample of seventy (70) respondents for quantitative approach and sixteen (16) participants for the qualitative approach were purposively selected for the study. The results reveal that old age grant gives beneficiaries an opportunity of spending, which in turn sustains impoverished and vulnerable communities. In this way, the old age grant strengthens existing, deep-rooted informal social protection systems and social networks. In the case of Dutywa community, this is seen in instances where beneficiaries of the old age grant enable many rural grandmothers to take care of their grandchildren and afford beneficiaries’ necessities. It was concluded that old age grant has positively reduced poverty in Dutywa community of Eastern Cape though it does not meet all their necessities. Appropriate recommendations were made in the study.

- 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.

- 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.

- Description: The quality of service from a hospital is the number one factor that will either turn a customer/patient away or make one for life. More and more hospitals are competing for greater shares in the market and customer-driven quality management is becoming the preferred method for improving their performance. Awali hospital is a private hospital in the Kingdom of Bahrain. It is a small 35-bed hospital that offers private medical services to the public. The hospital was originally built to serve the Bahrain Petroleum Company (Bapco) refinery workers but later opened its doors to the public. With the introduction of private patients came higher expectations of quality and higher demands on the overall services. A number of service quality shortfalls were identified over the years but never identified quantitatively by a patient evaluation survey. An English and Arabic version of the questionnaire based on SERVQUAL (Zeithaml, Parasuraman and Berry, 1988) was developed and placed in Awali hospital to test these service quality shortfalls. This study intends to evaluate these areas by answering questions about the relevant areas of service provided by the hospital. It measured patient satisfaction by looking at human aspects of service (responsiveness, reliability, empathy and assurance) with only one factor of the instrument being devoted to the non-human aspect of care rendered (tangibles). The SERVQUAL instrument has five dimensions that were measured by 21 pairs of item statements. One statement from each pair reflects perceptions, the other expectations. Measurement was accomplished by subtracting expectation from perceptions resulting in a service quality score. Positive or zero scores would reflect ideal or adequate service quality offered by the hospital. A negative score would be indicative of a service experience that did not meet customer expectations. Using the SERVQUAL questionnaire provided, quantifiable reasoning to the research questions in each dimension could be obtained so that precision, objectivity and rigour replaced hunches, experience and intuition as a means of investigating problem areas. Customers were first asked to supply some additional demographic information, for example gender, number of hospital visits, nationality, patient type (Bapco worker, general practitioner referred or private) and type of visit (inpatient, outpatient or both). They werethen asked to rate the hospital service on a 7-point Likert scale ranging from Strongly Agree (7) to Strongly Disagree (1). At the end of the questionnaire was space to write open comments. In total 600 paper questionnaires were distributed in the hospital, 300 English and 300 Arabic. Another 150 electronic questionnaires via emails were sent to refinery workers. Of the total 750 questionnaires distributed 162 were returned of which 156 (or 21.6%) could be statistically analysed. The empirical data results showed that the perception scores were significantly different at the p < 0.05 level from expectation scores. All the service quality differences (SQ=P-E) were negatively scored. This indicated that patients were not satisfied in all five dimensions of services offered by the hospital. Of the five dimensions responsiveness had the largest difference with assurance and reliability following with no significant differences between them. The demographic information revealed some interesting differences between the groups. Of all the demographic groups the most significant differences were between groups, “patient types” and “types of visit”, which showed differences between private patients and refinery workers and patients who used the hospital only as an outpatient and patients who used both services, outpatient and inpatient. In terms of the managerial implications, it was recommended that Awali hospital look to closing Gaps 1-4 of the SERVQUAL gap model which would result in closing the consumer gap, Gap 5. A process model for continuous measurement and improvement of service quality was recommended that looks at asking questions about how the hospital is performing. By adopting some of the recommendations identified in the research questions, Awali hospital could improve their quality of service, and as a consequence, their customer satisfaction and loyalty.

- Description: The objective of the study was to determine the management factors influencing lamb survival from birth to weaning in two ecologically different resource-limited communal farming systems. An annual flock monitoring study in the sourveld and sweetveld regions was preceded by a household check-all-that-apply (CATA). Lamb management practices and constraints faced in raising lambs in the two regions were determined using the check-all-that-apply technique. The results showed that the majority of the households were male headed (75.70percent) and consisted of the elderly (˃50 years, 79.44percent) who were not employed (82.24percent) and had attended primary school (67.29percent). Wool production was ranked the most important reason for keeping sheep in the two regions. The CATA revealed that the management systems between the two regions differed significantly (p˂0.05) in terms of assisting sheep at lambing, attending to twin births and dipping of mature lambs. Farmers‘ age was associated with the type of management performed (p ˂0.05). None of the farmers in the two regions performed navel dipping. Some of the reported constraints in the sweetveld were theft, diarrhoea and drought while predators and cold weather were the major constraints in the sourveld. The CATA identified vaccination and dipping as the major missing practices in both regions. The study showed differences in the use and choice of CATA terms which suggests that a ―one-size-fits-all‖ approach to solving poor management and sheep production constraints is not applicable. In the monitoring study, the results showed that veld type had no significant effect on the birth weights (2.0±0.09 kg) of the lambs. Type of birth had a significant effect (p<0.05) on the birth weights of the lambs. Single born lambs were 0.41kg heavier (p<0.05) than twin lambs. Single born lambs, however, showed an improvement in weights at 90 and 120 days where they had slightly higher weights than single born lambs. Male lambs were significantly (p<0.05) heavier (2.3±0.12 kg) than the female lambs (1.7±0.06 kg) at birth. The lamb birth were highest (P<0.05) in the hot-dry season. Lambs born in the cold-dry season were the lightest (1.63±0.13 kg). Lambs born in the post- rainy and hot-wet season were not significantly different (P<0.05). Weaning weights were not affected by veld type, birth type and sex, but were affected by season of birth. The lambs born in the hot-dry season had the highest weaning weights. The sourveld had a total pre-weaning mortality of 10.6percent while the sweetveld had a total pre-weaning mortality of 14.2percent. Animal housing from both veld types was poorly designed in terms of security against stock theft, drainage, hygiene, overhead shelter from the rain as well as access to feed and water. It was concluded that lamb management practices in the two regions were not the same. Performance of lambs before weaning differed according to veld type which played a role in feed availability during different seasons.

- Description: This study focused on the technical and institutional constraints faced by the vegetable co-operatives with regard to the impact on productivity. Vegetable co-operatives have no access to markets due to their poor performance on productivity and poor quality produce resulting to low prices for the produce such that they cannot compete in a market economy. In this study, the data was drawn from a sample of thirty vegetable co-operatives in the Buffalo City Metropolitan Municipality (BCMM) of the Eastern Cape; obtained through focus group discussions and interviews from each cooperative. The objectives of the study are to measure the productivity of vegetable co-operatives using Total factor productivity analysis (TFP) and profitability of vegetable co-operative using Gross Margin (GM). Followed by the descriptive statistics in identifying and assessing the socio-economic characteristics as well as coping strategies adopted by vegetable co-operatives in BCMM where percentages, means and tables are used looking at the highest frequency. The results show that the vegetable co-operatives in the BCMM are not productive and profitable due to major constraints experienced by co-operatives such as lack of market, information, trainings and business skills, capital, infrastructural facilities, effective extension services that all leads to poor produce quality. Co-operative is said to be profitable and viable if total revenue is greater than the total variable cost which makes the gross margin positive. In this case, the total gross margin is negative. The results showed that the production costs, maintenance (tractor hire, generator hire and servicing) and electricity costs were the major costs incurred in the production of vegetable by the co-operatives.

- Description: Since independence in 1990, Namibia’s Ministry of Education Sport and Culture has focused on curriculum and assessment reforms. The introduction of Continuous Assessment (CA) for appraising learners’ achievement was considered to be a very important aspect of teaching and learning. This study focused on the implementation of CA in schools. The study explores how the selected grade 7 Social Studies teachers understand and implement CA. This study was conducted in the Oshana region of Namibia. Four grade 7 Social Studies teachers participated from two different schools. This study was done through a case study to gain insight into the implementation of CA in schools. Semi-structured interviews, observations and document analysis were the research methods used to collect the data. The findings indicate that these teachers have a theoretical understanding of what CA implies and what role it plays and are aware of assessment strategies. However these theoretical perspectives are not translated into practice. This implies a limited understanding of CA and reflects a gap between the teachers’ theoretical understanding of CA and its practical implementation. The study also identified various systemic factors that hamper the implementation of CA, which include overcrowded classrooms, increased teachers’ workload by CA, shortages of resources such as textbooks and lack of professional development. The nature of pre-service teacher education the participants went through, professional development programmes that are given to teachers as in-service training and a lack of guidelines in the syllabus on how to approach continuous assessment are clearly evident in the findings as factors that contribute to the teachers’ gap between theory and practice. The study concludes that even though a number of workshops on continuous assessment were conducted, the teachers still could not implement it as expected. The study findings inform my professional context as an Advisory Teacher and that of my colleagues. Therefore it made me realize what the teachers’ needs are and what kind of support they require.

- Description: This research is an investigation of Zambian journalism educators’ conception of the knowledge, competencies and values that should inform their teaching practice. The study establishes how such educators conceptualise of the purpose of journalism education within the Zambian context. As part of this examination, it identifies characteristics of this context that educators regard to be of relevance to their conceptualisation of such purpose. It then identifies what they understand as the implications for the design of the ideal journalism education curriculum. The study assesses the relevance of these perspectives to the teaching of journalism in Zambia, as an example of an African country with a ‘developing’ economy. The study draws for its theoretical framework on journalism studies generally and scholarship about journalism education more specifically. It is argued that a review of the global history of journalism education points to the existence of three main traditions of teaching that have developed internationally. The first of these traditions is described as being dedicated to the project of ‘professionalisation’; the second to the production of ‘critical practitioners’, and the third to the project of ‘social development’. These traditions are based on different understandings with regard to the principles on which journalism education programmes should be based and the kind of knowledge that they should draw on. It is noted that this body of literature does not include extensive research of the way in which particular groups of African journalism educators respond to these traditions. In order to contribute to such research, the empirical component of this study sets out to explore Zambian journalism educators’ conceptualisation of journalism education within their own social context. It does so by means of an exploration of journalism educators based, respectively, at the Evelyn Hone College of Applied Arts (EHC) and the University of Zambia (UNZA)’s Mass Communication Department. The foremost conclusion of the research is that both the professionalising and developmental tradition can be observed to influence the participants’ discussion.
