  • Description: Tetraviruses are a family of small non-enveloped positive sense RNA viruses that exclusively infect members of the order Lepidoptera. Their replication biology is poorly studied because, with the exception of Providence virus (PrV), tetraviruses are unable to replicate in tissue culture cells. The overall aim of the research described in this thesis was to develop a fundamental understanding of the replication of tetraviruses, focussing on the site of replication within host cells and in particular, the subcellular localisation of the viral replicase. Helicoverpa armigera stunt virus (HaSV, Genus: Omegatetravirus) was chosen for this study because it is the only tetravirus for which the cDNAs have been shown to be infectious. In the absence of tissue culture cell lines susceptible to HaSV infection, the approach was to use confocal fluorescence microscopy to examine the subcellular localisation of the HaSV replicase fused to enhanced green fluorescent protein (EGFP) in mammalian and insect tissue culture cells. The replicase (with EGFP fused at its C-terminus) localised to punctate structures throughout the cytoplasm of transfected HeLa and Sf9 cells. These structures were then shown – using live cell imaging and time lapse photography – to behave similarly to cellular endocytic organelles and fluorescence partially overlapped with membranes containing the late endosomal marker protein CD63. Biochemical fractionation of Sf9 cells expressing the replicase via a recombinant baculovirus (as well as transfected HeLa and Sf9 cells expressing EGFP-replicase fusion proteins) demonstrated that the replicase was strongly associated with detergentresistant membranes (DRMs) in these cells. Deletion analysis of the replicase coding sequence revealed two regions involved in the generation of the punctuate structures. Firstly, the C-terminal half of the replicase RNAdependant RNA polymerase domain was found to be essential for targeting and the tight association with DRMs while the second region, within the Nterminal 44 amino acids, enhanced localisation through a combination of secondary structural elements and sequence-specific functions. A comparative immunofluorescence study on PrV, which replicates as a persistent infection in an insect midgut cell line, showed that the PrV replicase also localised to punctate structures in the cytoplasm. Biochemical fractionation showed that the replicase was also strongly associated with DRMs. This thesis describes the development of new experimental systems for the study of tetravirus replication biology and the data lead to the conclusion that the HaSV replicase associates with DRMs derived from alternate endocytic pathway organelles.

  • Description: In most African communities, the concept of disease goes beyond physical and mental pain. To many, societal imbalance, bad-luck, poverty and misery, misfortune, continuous unemployment and a host of others are treated as diseases. Despite biomedical attempts to explain and treat diseases, an ancient system of healing (traditional medicine) continues to thrive in Africa. The World Health Organization (WHO) has since recognized and encouraged governments to accept traditional medicine as an alternative healthcare; to adopt healthcare policies that will promote traditional medicine. Despite this call for recognition, most governments are still reluctant to officially incorporate traditional healing into healthcare policies. Countries which have recognized the relevance of traditional medicine face greater challenges on modalities to control and include traditional medicine into mainstream healthcare. This study is concerned with the role and contribution of African traditional medicine to healthcare, in an era of biomedicine. It provides a public and self assessment of traditional healers. The study also raises concerns on the need for healthcare policies that will enhance cooperation between traditional healing and biomedicine. Information was obtained through the use of questionnaires, in depth and face-to-face interviews with respondents. The actual field research was conducted in Qokolweni location in the King Sabatha Dalindyebo (KSD) district municipality of Eastern Cape Province, Republic of South Africa. Findings reveal that traditional healers handle and manage complex hospital diagnosed health conditions. It also reveals that perceptions on disease aetiology influence health seeking behaviour. It is therefore necessary to understand the efforts of traditional healers in order to formulate healthcare policies that would officially involve them in the mainstream healthcare in South Africa. It is noticeable that traditional healing is not only limited to Qokolweni. It occurs mutatis mutandis else wherein the Eastern Cape and in the whole of South Africa.

An investigation into the role of Xhosa male initiation in moral regeneration

  • Authors: Ntombana, Luvuyo
  • Date: 2011
  • Subjects: Xhosa (African people) -- Rites and ceremonies , Initiation rites
  • Language: English
  • Type: Thesis , Doctoral , DPhil
  • Identifier: vital:16132 , http://hdl.handle.net/10948/d1006265 , Xhosa (African people) -- Rites and ceremonies , Initiation rites
  • Description: This research study in Mdantsane (East London), Whittlesea (Hewu), Njiveni (Libode) and Cala sought to investigate the role of the amaXhosa male initiation in moral regeneration focusing on socio-cultural, educational and religious aspects related to moral values. The role of the amaXhosa male initiation as a rite of passage from boyhood to manhood, how it was viewed in the past, its impact upon the initiates and its contribution to the moral upholding of values were investigated. It was further intended to establish whether westernisation and urbanisation brought a shift of meaning and emphasis to the current initiation practice and, if so, to what extent has the ceremony departed from traditional norms and what challenges the ceremony has to face at present. A qualitative research method involving an ethnographic study was utilised, which includes in-depth, semi-structured interviews (formal interviews and informal discussions) and participant observation. Research findings suggested that in the past the amaXhosa male initiation played a role in the instruction of moral values. However, this study identified a shift of meaning in the practice which has been more evident in urban than in rural areas. The shift suggested that the instruction role has changed in prominence and there is less emphasis on teaching and appropriate adult behaviour. Moreover that the amakhankatha, who had the major role in teaching of the initiates are now participating in making the role less effective and sometimes introducing influences that are destructive to the initiates. Such negative influences include abuse of alcohol and drugs, promiscuity among the youth and disobedience of elders. It is argued that revisiting the teachings surrounding male initiation may cultivate productive debates on how young males are taught morality in today's society. Furthermore, that if the Xhosa male initiation could be contextualised it can play a role in the instruction of boys as they graduate to manhood and that can contribute to moral regeneration in South Africa.

  • Description: Zambian copper mines have embraced the use of information technologies for strategic operations and competitive advantage. This dependence on these technologies has not only been seen in the physical aspects of business operations but also in the use of information systems such as Enterprise Resource Planning Systems (ERPs) for strategic decision making and increased usage of Industrial Control Systems (ICS’) that are meant to enhance operational efficiency in production areas. A survey was conducted to explore leadership perceptions on information security practices in Zambian copper mines and an ISO/IEC 27002 Audit Tool was administered to middle management in a particular mine for an in-depth analysis of their information security practices. Results revealed that although information security controls may have been put in place in these organisations, there are still areas that require attention. Senior management and middle management have different perceptions as to the extent to which information security practices are conducted in these copper mines. This implies that management may not be fully involved in certain aspects of these organisations’ information security practices. The results concluded that management needs to be fully involved and provide support for information security programs. Furthermore, these information security programs should be standardised so as to effectively protect these organisations’ information assets. This should also include the involvement of personnel as key players in the information security process.

  • Description: This study investigated whether the funding of section 21 schools improves the quality of teaching and learning in six schools in the Mthatha Education District, in the Eastern Cape Province of South Africa. Despite the large funds that are pumped into schools by the Department of Education, the schools appear to be under resourced, underdeveloped and therefore underperforming. The researcher used the theories of school improvement to ground this study and to investigate whether the schools improve or not, and are offered support where necessary, as they are continuously being funded by the Department of Education. The study had these objectives: To investigate how the funds are spent by Section 21 schools in the Mthatha district of Education: to assess whether the SGB manages the spending of funds and whether there is any collaboration between the Principal and the SGB in financial issues and: to evaluate whether Procurement procedures are followed when purchasing. Systematic random sampling, amongst 6 schools, has been conducted. A questionnaire was administered to the school Principals, 2 Finance committe members, 1 Educator and 1 learner and SGB chairpersons from each of the 6 schools. Thus, both qualitative and quantitative methods of inquiry were used in this study. 3 Junior Secondary and 3 Senior Secondary schools were considered in the sample. The findings that emerged were a lack of capacity, on the part of SGBs to monitor recurrent allocations as stipulated in the South African Schools Act (No 84 of 1996). Another factor that emerged was that schools still need training and workshops on procurement procedures. Also evident was that there appeared to be little evidence of collaboration between principals and SGBs, especially in financial matters. Finally, recommendations and suggestions were made that schools need to be provided with a series of workshops on procurement procedures and policies. SGBs were to be capacitated so that they could be on board on financial management. The principals were to be encouraged to cooperate and be transparent on financial matters especially since, as stipulated in SASA, as an official of the Department of Education, the principal has a responsibility to advise the governing body when they issue instructions or act in a manner that contravenes departmental instructions or policy.

  • Description: The proliferation in the number of schools offering junior secondary education in Namibia since independence in 1990 has led to an increase in the number of learners in the classroom and has created a wide range of mathematical proficiency among learners entering senior secondary education in grade 11. This broad range of basic mathematical ability among these learners, together with increasing classroom numbers has caused problems for the senior secondary mathematics teachers (Batchelor, 2004). The study shows that diagnostic testing can prove to be useful in assessing learners’ mathematical preparedness by identifying learners’ areas of weakness, which have hindered their mathematics learning and performance. Taking the results of a diagnostic test into consideration could help teachers cater for their learners who need remediation classes as early as possible before extending the mathematics curriculum. Setting and using diagnostic testing requires careful consideration; there are many pitfalls that are highlighted in this research. These include question coverage and general analysis of category totals.

  • Description: Before the Republic of Namibia achieved independence in 1990, Bantu Education was the prevailing structure used to promote the social, economic, and political ethos of apartheid through a teacher-centered education system. After 1990, Namibia underwent a major restructuring of education. Learner-centered education was introduced as an inclusive and participatory approach to achieve the reform goals. One of the aims was to review the existing Language policy and to promote mother tongue teaching, since it is through language we internalize our experience and construct our own understanding. In other words, our cognitive, emotional and social development is dependent on language. In this case study, the understanding and implementation of a learner-centered approach in Namibia were investigated in order to gain insights about how the participating education officer, responsible for Oshindonga understands and assists teachers to implement this approach. At the same time, this study aimed at investigating Grade 11 teachers‟ understanding and implementation of LCE in their classrooms. The qualitative methodology in this case study used semi-structured interviews, classroom observations and document analysis for data collection. The data revealed that there are a number of misconceptions. In some cases, what teachers say is not what they do. The findings suggest that teachers, while attempting to implement a learner-centered approach, are not confident about its underlying theory, and therefore the degree of implementation depends on how the teachers used their understanding of that theory in their practice within these conceptual constraints. The study highlights particular challenges and problems that hinder the effective implementation of learner-centered education.

  • Description: The impetus for this study came from the findings of an evaluation of a Maths and Science through Arts and Culture (MStAC) Curriculum Intervention undertaken with Grade R teachers registered for a BEd(in-service) qualification at Rhodes University, South Africa. The intervention aimed to enrich Grade R teachers’ teaching of mathematics. Post-intervention classroom observations showed that, in spite of the intervention, teachers’ classroom practices did not change, and they were not using visual arts to teach mathematical concepts. This, together with the lack of research in the field of mathematics in early childhood, particularly in South Africa, motivated this research, a case study, which investigates how visual arts can be used to teach space and shape conceptualization in Grade R. I designed a research intervention underpinned by a constructivist model of teacher professional development located in reflective practice (Borko & Putman, 1995; Zeichner & Liston, 1996; Wilmot, 2005). Guided by Stacey’s (2009) notion of an emergent curriculum, I designed a three phase research intervention which involved selected Grade R teachers undertaking classroom-based research. Phase I built awareness around the notion of creativity; Phase II focused on making meaning of children’s behaviour and interests; and Phase III applied the knowledge and ideas from the Phases I and II to the teaching of space and shape. As an interpretive research study, it closely examines the participating teachers’ perceptions, experiences and reflections which were articulated in reflective reports and assignments. Following action research processes, the participant teachers engaged in the process of an emergent curriculum. They observed the behaviour interests of Grade R children, interpreted and made meaning of the evident behaviours, made decisions regarding extension activities, and planned accordingly. The findings of the study illuminate a model of teacher professional development that can support and enhance teachers’ practice. Understanding the notion of creativity and the ability to create a classroom conducive to creativity, are necessary components for teaching space and shape through visual arts activities. An emergent curriculum approach is proposed as an appropriate pedagogy for teaching children about space and shape through visual arts activities.

  • Description: There is no question that effective talent management requires a well-defined process. Talent management includes all talent processes needed to optimise people within an organization. The processes include: attracting, recruiting targeted selection, performance management, succession planning, talent reviews, development planning and support, career development, and workforce planning. The hired employees should be developed to mould into the organization culture so that they support the vision and mission of the organization. Retention of key employee is critical to the long term success of business as it ensures customer satisfaction, product sales, and satisfied co-workers, reporting staff, effective succession planning and a deeply embedded organisational knowledge and learning culture. iii The research problem in this study was to investigate how successfully Talent Management and Employee Retention strategies been implemented at the Bank of Zambia. To achieve this objective a comprehensive study was undertaken on talent management and employee retention. The study involved conducting a literature survey to understand the processes that are necessary for implementation of talent management and employee retention in an organization. An empirical study was later conducted to investigate whether the processes of talent management and employee retention have been successfully implemented at the Bank of Zambia. The survey was compared to the literature review to determine whether the Bank of Zambia complied with the findings in the literature review. The main findings from this research are that for talent management to be successful, the initial step of planning right from the strategic point of aligning to talent goals to business goals through to succession planning should be well conducted. This process needed special attention. As much as the empirical study showed a case of progress towards engagement, there was concern raised regarding job security. Some employees perceived that they were insecure in their job. Compensation and rewards were also perceived to lack equity in their distribution and that promotion and career progression were below expectation for may employees The final observation from the investigation was that the organizational culture was not well adopted by respondents. . Employees perceived that the culture did not support innovation and the rewards system did not provide incentives for better performance.

  • Description: Changes in assessment practice in education are a global issue. Colleges of Education in Namibia also need to accommodate these changes in their training programs for student teachers, to model their practice of all modes of assessment in teaching and learning. Emphasis should be placed on assessment for learning, which is formative in nature. This qualitative case study investigated the following questions: How do teacher educators understand the principles and strategies of formative assessment and how do teacher educators implement formative assessment in their own teaching, which in turn serves as an example to their student teachers. I used three methods of collecting data: interviews, observation and document analysis. The data identify a range of findings in the teacher educators' professed understanding of formative assessment and how it is implemented in their own practice. The data also identify challenges facing the teacher educators in terms of setting a good example to their student teachers in the area of formative assessment. This study also offers suggestions for further studies on formative assessment. These include a suggestion for teacher educators to look at their own practice of formative assessment principles and strategies. A major cross department study could be conducted that includes teacher educators from different subject areas to see to how the implementation of formative assessment in the college varies from one department to another. A third possibility suggests a study involving student teachers from various areas of specialization in the college to see to what extent the implementation of formative assessment in the college affects their future assessment practices.

  • Description: Abstract This study presents the characteristics of small-scale gravity waves in the mesosphere region as derived from the imaging riometer data at high altitude (~90 km) over SANAE (72˚S, 3˚W). Wavelet analysis and FFT (Fast Fourier transform) have been applied to extract short period gravity wave parameters for the year 2000. The horizontal wavelength, phase speed and observed period of gravity waves are typically 10-100 km, 5-60 m.s-1 and 3-60 minutes, respectively. The horizontal propagation direction is north-eastward throughout the year. This could probably be due to selective filtering by the zonal wind. Zonal and meridional winds in the region of the MLT (mesosphere and lower thermosphere) have been measured using HF radars at high latitudes in the southern hemisphere. Data from January 2000 to December 2003 have been used with the aim of investigating the characteristics of planetary wave activity at ~90 km. For SANAE and Halley stations, 2-, 5-, 10-, 16- and 20-day planetary waves are dominant in summer and winter. The results show the seasonal variations of the mean winds, which are caused by the internal variability of the quasi stationary planetary waves. Planetary wave coupling processes between UKMO assimilated and mesospheric data have also been investigated. The cross wavelet results show a strong coupling during winter months. The results suggest that planetary waves are generated at lower atmospheric heights and propagate upwards into mesospheric heights. However, not all observed disturbances in mesospheric heights can be explained by the propagation of planetary waves from lower atmospheric heights.

  • Description: The South African Police Service (SAPS) as a constituent part of the public service was established to deliver a specific category of services to the public. These services have to conform to requirements that are prescribed by various legislative provisions to promote effective and efficient delivery of public services. The implications of these provisions that are pursued by the study firstly, refer to the emphasis of government on the enhancement of public service delivery, with due consideration given to cost effectiveness and efficiency. Secondly, it refers to government's realisation of the important impact of education, development and training (EDT) on the competency of public service officials with an emphasis on the utilisation of information technology to enhance the effectiveness of EDT. Consequently, the study explores the viability of the utilisation of information technology as a measure to assist EDT interventions within the SAPS of the Eastern Cape Province to equip members of the institution to better fulfil their functions and duties. In this respect the study commenced to ascertain the levels of computer literacy of role-players, access to the appropriate facilities and what the general attitude in the organisation would be towards the utilisation of such an intervention. It was found that the computer literacy levels of role-players may be perceived as a problematic issue in this regard. However, access to suitable facilities was found to be more than sufficient for this intention. Furthermore, role-players agreed that information technology could be optimally applied in the EC SAPS for the mentioned use, thereby portraying an optimistic attitude towards the use thereof to harmonise EDT in the SAPS. The aim of the study has been to develop a model that will incorporate the use of information technology, given the strengths and weaknesses of the SAPS to enhance EDT and learning in the organization.

  • Description: The purpose of this study was to investigate the empowerment needs of councillors in a municipality. The main focus was to assess the successes or inadequacies of the empowerment programmes previously offered to councillors by the King Sabata Dalindyebo Local Municipality. In order to achieve the research objectives an in-depth literature study was undertaken. A survey was also conducted to examine the level of empowerment being offered by the King Sabata Dalindyebo Local Municipality to its councillors and the data was collected by means of self-administered questionnaires. The literature study proved the hypothesis to be correct, which stated that empowered councillors could enhance effective public participation, effective communication which could result in effective service delivery. The empirical study revealed that certain councillors require adequate training in areas such as communication skills, council’s rules of procedures and new developmental mandate assigned to local government. The empirical survey also revealed that there is limited mutual trust between councillors and the senior officials, immediate intervention is required to restore trust between councillors and officials. It has been recommended that King Sabata Dalindyebo Local Municipality should not only provide regular “in house” training, but also training conducted by outside agencies is required. In certain instances, one may find that municipalities may not have fully capacitated persons for “in house” training. Thus, outside agencies which possess the relevant expertise such as universities and SALGA should be encouraged to also facilitate capacity training for councillors.

  • Description: This treatise investigates the role of Community DevelopmentWorkers, with reference to the Bitou Municipality. The treatise comprises five chapters. The concept of Community Development Programme is fairly new in South Africa; therefore, further research is needed on the subject. A literature review was done to establish the concept and the background of the CDWP. A questionnaire was developed in order to obtain primary data from a selected sample group. The data obtained from the questionnaire was statistically analysed and interpreted. The core findings from the analysed questionnaire indicated the following: (a) CDWs clearly understand their role and responsibility, but there is a need for roles and functions to be clearly defined, with detailed terms of reference, to ensure a common understanding with other stakeholders, e.g. Ward Committees, Councillors, Non-governmental organisations, Communitybased organisations, and members of the community. (b) living conditions in the wards improved following the introduction of the CDWP. (c) there is a good relationship between CDWs, Ward Committees and Ward Councillors, but there is also a perception that Ward Committees and Community Development Workers constantly clash or compete in the wards in which they serve. (d) CDWs should not be affiliated to the ruling or any political party. (e) CDWs are confused regarding who is responsible for their remuneration (the Municipality or the Provincial Department of Local Government).

  • Description: Around the globe, towns and cities are growing rapidly in developing countries due to migration. The rate of urban growth outweighs job creation and the ability of most governments to provide basic services and infrastructure. The process of migration often precipitates into high levels of poverty and hunger, leading many urban dwellers to engage in agricultural activities to help themselves in satisfying their food need. The context of the research area is the NMBM townships where urban agriculture projects are taking place. There are three urban agriculture projects that were selected for this study and these are located in three different townships within the NMBM. Two of these projects are located in the Port Elizabeth area, which are the Emmanuel Haven Hydroponics Project, which is located in Motherwell Township, and the Walmer Hydroponics Co-operative that is in Walmer Township. The third project is located in the Uitenhage area near Kwa Nobuhle Township and that is the Tinarha Agriculture Tourism Initiative (TATI). The discussion in this research focuses on the NMBM poverty alleviation projects in the form of urban agriculture as a key driver of LED. The discussion also focuses on different factors that are required for urban agriculture projects to be effective and sustainable in the NMBM. Five project participants from each project responded to a structured questionnaire. Two municipal officials, the Agricultural Technician and the Urban Agriculture Director were interviewed and responded to a separate structured questionnaire. The third official, Assistant Director for Economic Development and Recreational Services was not interviewed but completed a questionnaire. The aim of the interviews was to determine the following from the project participants: (i) The impact of the projects in their livelihood; (ii) The role of the projects in creating employment; (iii) The views of the project participants regarding the sustainability of the projects. vi The aim of the interviews was to determine the following from the municipal managers: (i) The approach of the NMBM to urban agriculture initiatives as a LED strategy; (ii) The role of NMBM to ensure sustainability of the urban agriculture projects. The theoretical base that underpins this research hinges on four theoretical approaches: the basic needs approach, the people-centred development approach, the participation approach and the sustainable development approach. The research method that was chosen for this study is qualitative method included the following data collection instruments a literature review, a documentary analysis, a survey using questionnaires and interviews with project participants and municipal officials responsible for urban agriculture in the NMBM. The literature review formed the conceptual basis against which the information gained from documentary analysis, interviews and questionnaires were analysed. The projects that participated in the study were formed, amongst others, to alleviate poverty, thereby serving one of the basic needs which is food. Food is one of the basic needs in terms of Maslow‟s Hierarchy of Needs. The data collected in this study revealed that the three projects helped the project participants a great deal in meeting their basic needs, especially the food need. Therefore, there is a direct connection between the Basic Needs theory and the rationale behind the formation of these projects. In conclusion, the researcher has been able to draw a link between the theoretical underpinnings of the study and the practice as represented by experiences of the group sample. The researcher has also been able to demonstrate how the aims and the objectives of the study have been met.

  • Description: An investigation on how educators experience their workloads against the background of teacher shortage. This research study seeks to explore educators’ experiences of the effects of educator shortage on the academic performance of Grade 12 learners in the Butterworth Education District, in the Eastern Cape Province of South Africa. The research study was a result of the South African literature in education which over- emphasises the poor quality of teacher development as though it is the only cause of the poor academic performance of learners in South African Senior Secondary Schools. For example, the Centre for Education Policy Development Evaluation and Management (CEPD) (2000, p.130) asserts that “Training for educators and managers has been spotlighted in the Curriculum Review Report”. Through this study the researcher wanted to explore other possible explanations for the poor academic performance of the Grade 12 learners in the Butterworth Education District. The research study seeks to investigate whether educator shortages in Senior Secondary Schools could be responsible for the poor academic performance of learners in Grade 12. It was imperative therefore to look into the views and experiences of educators in this regard, with the object of finding the extent of educator shortages in schools, and the possible measures to address the situation, if it is a reality in schools. Six schools were selected, with each providing five participants who made a sum of 30 educators who volunteered to participate in the study. The study was an interpretive survey, where the qualitative methodology was used. The data was collected using semi-structured interviews. A tape recorder was also used to ensure that participants were not misrepresented in the analysis and discussions of the findings. The data was presented, analysed and discussed according to the patterns and themes derived from the sub-research questions. It emerged from the study that there are educator shortages in most senior secondary schools in the Butterworth Education District. This was due to the policies and reports which were contrary to one another. Contradictory reports were produced by three highly respected research institutions the National Teacher Educator Audit (NTEA) there was an oversupply of educators in South African schools (Hofmeyr and Hall 1996). On the other hand the research was conducted by the Pre-Service Education and Training (PRESET) and In-service Educational Service and Training (INSET) published that there is serious educator shortage in South Africa. There was a lack of insight from the Management of the National Department of Education, together with the Provincial Managers of education. These managers of the DoE failed to note that the decisions that they had made in 1994, of ensuring that all learners between ages of 7 and 15 should be taken by parents to school, would negatively affect the future of education if it was not properly planned for. This call for all learners of the above mentioned ages to go to school was made in line with the South African Schools Act No. 84 0f 1996. The implication of the Governments call to send more learners to school, whether parents had money or not, was that more educators had to be employed in the future but that did not happen. Instead, a once-off policy of severance packages was implemented by the government, which led to a lot of good educators taking their packages and leaving the profession. Literature reveals that Teacher Training Colleges were closed at about the same time. The literature also reveals that before the closure of Teacher Training Colleges there was a challenge of redeployment which was also not properly planned, implemented and monitored by the Provincial Managers of the DoE. The study reveals that poor planning of this process led to overcrowded classrooms, a phenomenon which was further exacerbated by the fact that the salaries of Principals and the HoDs in schools were linked to the number of learners the school had admitted. This had its own ramification like schools over-admitting learners because it meant more money for the principals and Heads of Departments. The study has revealed serious consequences which emanated from the educator shortage as a result of overcrowded classes. The literature also reveal that educators get employed and use the profession of teaching as a stepping stone for better paying professions. According to Peltzer, et al. (2005, p.35) “around 21 000 educators were leaving the system annually, although up to 30% of these were temporary teachers.” South Africa faces challenges with its pool of available educators. One of these challenges is that of attracting new educators into the teaching profession and another is the challenge of how to retain those already in the system (DoE, 2005 p.13). In the event that there are teacher shortage in the system the DoE is using the available educators to teach larger classes than they are capable. This causes problems when these teachers have to teach outside their areas of specialization. These consequences include the fact that educators are teaching more than six classes a day, and educators are overloaded; they do not have sufficient time to provide individual attention to the learners, mark leaner assessments, provide feedback on time, or do remedial work. The study also revealed that most educators are suffering from burnout and stress due to too much workload. The study has also shown that educators work even on Saturdays and holidays to try to finish the syllabus. As a result, there are very few young stars who aspire to making education their career. More educators are changing their careers because they know that life is about improved standards of living. The question is: What is the use of having all the good policies aimed at improving the quality of teaching and learning if there are insufficient implementers (educators) of these policies in schools. The policies include School Based Assessment (SBA), Annual National Assessment (ANA), Systemic Evaluation, Common Tasks for Assessments (CATs), Whole School Evaluation (WSE) and the Integrated Quality Management Systems (IQMS). Recommendations have been proposed on the strategies that the DoE may employ to address the educator shortage in schools and the quality of education.

  • Description: This is a comparative study of parental involvement in the governance of public and private schools in the Matatiele District of the Eastern Cape Province of South Africa. Parental involvement can range from occasional attendance of the school functions to partnership through parent teacher organizations and parent management bodies. Education is a national enterprise that requires the co-operation and participation of all the role players who are parents, community, teachers, learners and the Department of Education. The problem to be investigated in this study is: Why is it that parental involvement is more positive in the governance of private schools than that of public schools? Two schools were selected for the study and the researcher administered questionnaires personally by hand and conducted face to face interviews to collect the primary data. The responses of the administered questionnaire were tabulated and recorded in table form so as to give an accurate interpretation of what was revealed in the data. Patterns in the data were considered in order to provide an accurate interpretation of the information. The findings were divided into two, that is: findings from the public school and those from private schools. From the public school it was found that: parents are not involved in the governance of the school; the school does not involve parents on financial matters; parents do not attend meetings when invited; they do not know their roles and responsibilities, for example, according to the South African Schools Act (SASA), parents must be actively involved in the governance of the school in their community and that there is an element of ignorance and negligence on the part of parents towards their children’s education. From the private schools it was found that: parents are more involved in the governance of the school; they attend and participate actively in school meetings; the school involves parents in financial matters and as such the financial support from the parents is very good; parents are much involved in the monitoring of the progress of their learner’s education and are passionate about the school and seem to own the policies and the governance of the whole school system. The conclusion drawn from the study is that private schools allow for parental involvement in the governance of their schools whereas in public schools parental involvement is low.

  • Description: A Ni(II)-dimethylglyoxime ion imprinted polymer {Ni(II)-DMG IIP} was synthesized by the trapping method using the bulk polymerisation format. The structures of the imprinted and non-imprinted polymer were evaluated by infrared spectroscopy and the morphology was observed by scanning electron microscopy. The Ni(II)-DMG IIP was optimised for pH, mass, time and by the uniform design experimental method for the molar ratios of monomer to crosslinker to porogen and template to ligands as well as keeping these parameters constant and varying the quantities of initiator, 2,2'-azobisisobutyronitrile (AIBN). The optimum pH was 8.5, optimum mass was 50 mg, optimum time was 1 min and the optimum molar ratios of crosslinker to monomer, monomer to template and nickel(II) sulfate hexahydrate (NiSO₄.6H₂O) to 4-vinylpyridine to dimethylglyoxime were found to be 3.3:1.0, 0.6:1.0 and 1.0:0.6:3.6 respectively with 30 mg and 8 mL as the optimum amounts of initiator and porogen respectively. Through this optimisation, recovery of Ni(II) was increased from 98 to 100%. Selectivity of the ion imprinted polymer was evaluated by analysing, using an inductively coupled plasma-optical emission spectrometer, for Ni(II) ions that were spiked with varying concentrations of Co(II), Cu(II), Zn(II), Pd(II), Fe(II), Ca(II), Mg(II), Na(I) and K(I) in aqueous samples. Selectivity studies also confirmed that the ion imprinted polymer had very good selectivity characterised by % RSD of less than 5 %. Co(II) was the only ion found to slightly interfere with the determination of Ni(II). The limits of detection and quantification were found to be 3x10⁻⁴ μg/mL and 9x10⁻⁴ μg/mL respectively. The method was evaluated by a custom solution of ground water certified reference material (SEP-3) and sandy soil reference material (BCR-142R) and the concentrations of Ni(II) obtained were not significantly different to the certified ones. The Ni(II)-DMG IIP was then evaluated in aqueous and soil samples where recoveries of 93 to 100% and 98 to 99% respectively were obtained with enrichment factors ranging from 2 to 18 in aqueous and 27 to 40 in soil samples. Finally, the Ni(II)-DMG IIP was used to analyse mine tailings samples and Ni(II) recovery of 99% was obtained with an enrichment factor of 2.

  • Description: The challenge for Namibia is to translate Vision 2030 into realistic and implementable programmes and to develop and adopt a set of interventions which will raise the quality of education. The quality of education currently on offer varies from school to school and, indeed, from class to class (Namibia. MoE, 2006, p. 1). The National Standards and Performance Indicators (ETSIP, 2006) for schools in Namibia and the Education and Training Sector Improvement Programme (ETSIP), have been developed to address the quality of education across the country, and to make provision for school managers to be trained. Organisation Development is a planned change approach which focuses on the change processes of the organisation, by opening up communication, decreasing internal destructiveness – such as win-lose conflicts – and by increasing creativity in problem solving. It is based on the values and assumptions about people and their organisations. OD promotes interdependence and interconnectedness, involvement in problem solving and decision making. OD is a process for teaching people how to solve problems, take advantage of opportunities, and learn how to do better over time. OD was introduced to Evergreen Senior Secondary School in the form of a Survey Data Feedback (SDF) where data was collected, analysed and fed back to the participants. The case study involved 20 staff members made up of the principal, two head of departments and 17 teachers. Formal and focus-group interviews, as well as observation, were used to collect data. What was derived from the data was that the OD approach was something new to the participants, and served as an eye-opener. Further, it became evident from the data that participants had high hopes that OD would bring about immediate visible changes regarding the operation of their organisation. It is essential to remind participants that OD is a long-term change process, and not a “quick fix”.
