- Description: Contact Centres (CCs) are at the forefront of interaction between an organisation and its customers. Currently, 17 percent of all inbound calls are not resolved on the first call by the first agent attending to that call. This is due to the inability of the contact centre agents (CCAs) to diagnose customer queries and find adequate solutions in an effective and efficient manner. The aim of this research is to develop an intelligent user interface (IUI) model to support and improve CC operations. A literature review of existing IUI architectures, modelbased design and existing CC software together with a field study of CCs has resulted in the design of an IUI model for CCs. The proposed IUI model is described in terms of its architecture, component-level design and interface design. An IUI prototype has been developed as a proof of concept of the proposed IUI model. The IUI prototype was evaluated in order to determine to what extent it supports problem identification and query resolution. User testing, incorporating the use of eye tracking and a post-test questionnaire, was used in order to determine the usability and usefulness of the prototype. The results of this evaluation show that the users were highly satisfied with the task support and query resolution assistance provided by the IUI prototype. This research resulted in the design of an IUI model for the domain of CCs. This model can be used to assist the development of CC applications incorporating IUIs. Use of the proposed IUI model is expected to support and enhance the effectiveness and efficiency of CC operations. Further research is needed to conduct a longitudinal study to determine the impact of IUIs in the CC domain.

- Description: The study investigated the acceptance of electronic (e-learning) based instruction in selected South African companies based upon the dominants of e-learning acceptance that included computer self-efficacy, perceived usefulness, perceived ease of use and behavioral intention to use. A quantitative research methodology was conducted on a sample of male and female trainees in selected South African companies using e-learning as a mode of instruction (N=191) using the “E-learning Acceptance Measure” by Ong and Lai (2006). Analysis of variance was used to determine whether the biographical characteristic of gender could account for any differences towards the determinants of e-learning acceptance. Multiple stepwise regression was used to determine differences between dominants of e-learning acceptance and gender. The results of the study showed that there were no statistically significant differences in mean between men’s rating of computer self-efficacy, perceived usefulness, perceived ease of use and behavioral intention than that of women. In terms of influences, the results show the existence of influence between certain dominants of e-learning acceptance however no gender differences were found in influence. Recommendations were made based upon these results on how South African companies can help trainees accept and use e-learning.

- Description: Introduction : South Africa is currently engaged in wide-ranging consultations to formulate a new policy on education in line with the major structural changes currently taking place at the national level. The process has focused mainly on the previous government’s discriminatory policies, which were a cornerstone of apartheid. This research is not concerned so much with policy restructuring as with current pedagogical problems, which are a direct result of policy. During contact with students in different faculties at Technikon Free State over a period of nearly two to three years, made it clear that students experienced major learning problems especially in their first year. The research by Selaledi (1996: p8) seems to reflect one common origin which could be summed up as under-preparedness which, will leads to a high failure and drop-out rate among students. The higher education system is also beginning to respond to the changed social order as reflected, for example, in the changing demographic profile of students’ enrolment. However, the overall effectiveness and efficiency of the system is in doubt, as evidenced by a range of systematic problems (NPHE, 2001:p7-8). These include the overall quantity and quality of graduate research output. The contribution of the study will address aspects of the high failure rate as it has been outlined as a problem in the national plan for higher education. Large numbers of students who attend tertiary institutions are not able to deliver the academic standard of work expected from them. This often results in high failure in other subjects (Esterhuizen, 1995:p15). Technikon Free State declared certain subjects at risk and Accounting Education was included in the list. The high failure rate at tertiary institutions could be ascribed to the difference between the expectations of the lecturers and those of the students (NPHE, 2001:p7-9). Learners who take Accounting at high school spend five years doing the subject. This should give learners a solid grounding for future advanced studies in Accounting. However, according to Fridman (1987:p7-8) this, is not the case, as high school Accounting does not influence the result of first year Accounting. This study proposes to investigate the factors that influence the results of Accounting Education I at Technikon Free State. The study will also determine whether Grade 12 Accounting plays an important role in Accounting Education I results. The research findings may contribute towards a better understanding of the factors that influence academic performance in this field.

An investigation into masculine-atypical behaviour : a study among Moi university students Western Kenya

- Description: We are presented with a situation in which ‘the male identity is a fragile and tentative thing with no secure anchorage in the contemporary world’ (Brittan, 1989:3). However, empirical evidence surrounding the commonly perceived contemporary crisis of masculinity fails to support any overall crisis of masculinity thesis (Edwards, 2006:16). Instead, the different perceptions of the crisis tend to rest on at least one of the three propositions pointed out by Edwards (2006:17): Firstly; masculinity as a set of values, practices or dispositions may be suffering a crisis in so far as it is being undermined and devalued, or, moreover that masculinity per see is now to a greater or lesser degree equated with a series of negative rather than positive associations and connotations. Secondly; masculinity may be in crisis due to its perceived tendency to implore into femininity, whether through an undermining of any gender role distinctions or through feminization of some forms of masculinity as, for example, in the case of the rise of contemporary consumerist, fashion conscious or sexually uncertain masculinities such as metrosexuality. Thirdly, the crisis of masculinity may relate to the sense that masculinity in terms of the male sex role is itself ipso facto crisis-inducing. In this sense, masculinity is not in crisis, it is crisis. This study was based on the second proposition. In the patriarchal Kenyan society where gender roles are fairly traditional, and the male person perceived superior to the female and male things valued above female things, the aspect of feminization of masculinity is not just new but indeed strange. This investigation was intended to find explanations for the feminizing behaviour by males. The sex role paradigm developed in the 1970s explains acquisition of masculinity through socialization, sex role learning and social control. These mainstream theories of learning gender were explored in the assumption that they form the basis for the contemporary theories, and further, although much had changed with the times, a large part of the society still perceived gender roles from this traditional viewpoint. The masculine crisis theory and the constructionist views of gender constituted the theoretical framework of the study. This was due to the researcher’s acknowledgement that individuals were active participants in the construction of their own gender identity, and that there was likelihood for the individuals to deviate from the social expectations of what masculinity means and should be. As a result they could construct a masculinity that did not reflect normality, hence portraying a crisis. Data relating to the respondents’ perception of and reasons for feminine behaviour among young male adults was gathered from young males, young females, and both male and female parents through questionnaire and interview methods. Information about the home environment of the respondents was also necessary to help explore environmental factors that contribute to gender construction. In addition, observation was used to obtain information to dispute, confirm or complement the findings from the other mentioned methods. An exploratory-descriptive qualitative type of research was undertaken at Moi University, Eldoret in Kenya, where the feminization of masculinity was observed. 100 male students chosen through both purposive and simple systematic sampling responded to the open-ended questionnaire which contained perception-eliciting items. A discussion with two focused groups of seven female students each, from the same institution obtained their opinion on the subject of cross-gender behaviour of their male colleagues. Selection of the females was based on willingness to participate. An in-depth interview with two male and three female parents of young male adults whose selection was upon availability, was done on a one-on-one basis to capture the view of adults (likely reasons for, and attitudes) on the matter of feminine behaviour among boys. Data was qualitatively processed and analyzed, taking into account issues of dependability and accuracy. Explanations, findings and conclusions were made, based on the fairly rich data. Overall, the researcher concluded that an interplay between various factors in the young males’ environments, including peers, media, parents and the general dynamics of society (including the feminist movements) explained the feminization of the masculine identity. All these were perceived as influenced by the postmodern movement that had transcended boundaries, thanks to modern communication techniques, to reach the initially very traditional societies. The researcher acknowledged the irreversibility of the clock of time and behaviour trends, hence suggested inclusiveness of this group of males for overall society development, but against the backdrop of responsible guidance and understanding. The study was seen as significant, both for education as an institution that empowered individuals for social function, as well as for peaceful coexistence for the society at large. Conclusively, a redefinition of ‘masculinity’ and a change in the current social attitudes about masculinity and femininity was recommended. Hopefully this was a step towards enhancing an understanding of behaviour dynamics in the largely changing social systems which, in the same vein, remained the touchstone for behaviour formation, modification and prediction not only in Kenya, but Africa as a whole.

- Description: The objective of the study was to investigate challenges affecting the effective implementation of the Public Finance Management Act, 1999 (Act No. 1 of 1999 as amended by Act No. 29 of 1999) in the Eastern Cape Province with specific reference to the Provincial Department of Public Works. The research study has been conducted in such a manner that the reason to send a team of experts by the DPSA on approval by the President to come to the Eastern Cape and assist the ailing administrations of four departments is determined. The four departments that had a problem were: 1. Department of Roads and Public Works 2. Department of Health 3. Department of Education and 4. Department of Social Development The roads function of the Department of Roads and Public Works was later transferred to the Department of Transport and the Department of Roads and Public Works changed the name to Department of Public Works in September 2004. The team that was sent to the Eastern Cape together with the Director-General of the Province and the Superintendent-General of the Provincial Treasury formed up the IMT. The objective was to introduce turnaround strategies that would enable the four departments to effectively and efficiently implement the PFMA to the best interest of the South African Government. The PFMA is part of the broader strategy on improving public financial management in the public sector in the Republic of South Africa. It prescribes measures to ensure responsibility, accountability and transparency in national and provincial departments. Qualified Auditor-General’s reports for the previous financial years compelled the President in 2002 to establish Interim Management Team (IMT) in the Eastern Cape, comprising of experts from national government, to assist the ailing administration in four provincial departments, including the Department of Roads and Public Works. Questionnaires to employees, Auditor-General, Provincial Director-General, Superintendent-General of Provincial Treasury and as well as to the Accounting Officer of the Department of Public Works, were designed and issued out for completion. Interviews were also conducted to some of the employees. The assumption is that the majority of employees do not understand policies and procedures of the department and they displayed this by remaining neutral in questions asked and disagreed with some of the statements. During the interview process, the majority emphasised their protest against over usage of consultants by the department. Preference given to candidates from outside the department when senior posts are advertised instead of looking for excellently performing candidates from the internal ranks of serving employees, has been outlined as one of the elements contributing to low moral and low productivity in the workplace. Over usage of consultants and a big number of employees who disagreed with statements and remained neutral signify incapacity of the management to perfectly implement the PFMA for sound public financial management in the department. It has been established that regular risk assessments are not conducted, poor organisational structure with many posts that are not filled, no Anti-Corruption Unit to implement Public Service Anti-Corruption Strategy and, no clear managerial lines of accountability due to poor planning, ineffective internal controls and procedures, all render the department incapable of becoming one of the best provincial departments that get unqualified audit report from the Auditor-General. The findings provide clear indication that drastic transformation of the department into an institution that can perfectly implement the PFMA is necessary. The implication is that mismanagement of financial resources and fraud and corruption defeat service delivery objectives. Strategic objectives of the department are not achieved. The Eastern Cape Provincial Departments are obliged to align their strategic plans to the Provincial Growth and Development Plan (2004 – 2014). Therefore the implication is that, poor performance by the Department of Public Works impacts negatively to this provincial objective. Lack of effective control systems has negative implications on the administration of the department and renders it vulnerable to fraud and corruption.

- Description: Currently, the IEEE 802.11 standard is the leading technology in the Wireless Local Area Network (WLAN) market. It provides flexibility and mobility to users, which in turn, increase productivity. Opposed to traditional fixed Local Area Network (LAN) technologies, WLANs are easier to deploy and have lower installation costs. Unfortunately, there are problems inherent within the technology and standard that inhibits its performance. Technological problems can be attributed to the physical medium of a WLAN, the electromagnetic (EM) wave. Standards based problems include security issues and the MAC layer design. However the impact of these problems can be mitigated with proper planning and design of the WLAN. To do this, an understanding of WLAN issues and the use of WLAN software tools are necessary. This thesis discusses WLAN issues such as security and electromagnetic wave propagation and introduces software that can aid the planning, deployment and maintenance of a WLAN. Furthermore the planning, implementation and auditing phases of a WLAN lifecylce are discussed. The aim being to provide an understanding of the complexities involved to deploy and maintain a secure and reliable WLAN.

- Description: The South African banking industry is currently facing increasing macro- and micro-environmental pressures which had led banks to move towards customer-oriented strategies. This has influenced the way their systems and processes are developed and innovated to provide a satisfactory service to their clients. It appears that service quality has been the differentiating factor that has set the competitors apart in providing their customers with a unique customer experience through client relationships and interaction. As a consequence, banks have resorted to implementing various training and leadership interventions as a driver, to effectively empower their employees to improve service quality The aim of this research study was to identify the impact that training and leadership programmes implemented by a particular branch of Standard Bank South Africa (SBSA) had on employee empowerment. This was achieved through a comprehensive literature review and an empirical study to measure whether employees had perceived themselves to be empowered. The results from this study will be used by the Human Resource Division of SBSA to evaluate and implement effective training methods for the employees of the selected branch in order to improve employee empowerment. This would serve as a great benefit for the bank as employees that are satisfied with the work are generally more productive, hence producing increased revenue for the organisation. An empirical study was embarked on to measure the respondents’ perception of being empowered and involved a survey of eighty-three employees of the retail branch in the Sandton, Johannesburg area. Forty-three of the employees responded to the anonymous questionnaire and the data obtained was analysed and interpreted into meaningful results. The results of the survey indicated that the majority of the employees at the selected branch perceived themselves to be empowered and it was concluded that the implementation of the training and leadership programmes by SBSA had a positive impact on them. The following recommendations were made: - Firstly, to increase training and development, in the form of leadership courses, inter-departmental learning and on-the-job training sessions to develop the employees to their full potential; - Secondly, management needs to encourage employees to participate in discussion forums and staff meetings and involve them in decision-making thus improving the perceived lack of a free-flow of information and transparency within the workplace; - Thirdly, team leaders and supervisors should encourage support and coaching of the junior employees by giving them constructive on-going feedback, supporting their ideas, delegating tasks, and giving them direction on the way forward; - Fourthly, a review of the reward and recognition system would be advisable where employees are rewarded (financially or non-financially) for a job or task well done, or to promote certain behaviours and attitudes in the workplace; and - Finally, it was recommended that the employees be informed and educated on the benefits, associated for both the employees and the organisation, of the Scheme in order to increase their commitment and performance. The empowerment of employees in the organisation is important as it involves employees who take responsibility for their decisions and actions because they are primarily the ones who solve the problems in their own teams. Empowerment in organisations can thus lead to less absenteeism, lower employee turnover, less employee training costs, increased employee satisfaction and more productive employees.

- Description: Shortly after independence, Namibia embarked on a major process of educational reform. It was in this reform that the apartheid educational legacy was redressed. Namibians viewed the apartheid educational system as being irrelevant and that it did not meet their needs and expectations. One of the reform aims was to involve education in the development of knowledge and skills for self sufficiency and sustainable development, therefore Agriculture was incorporated into the school curriculum as a key area to achieve this aim. Learners taking the subject are expected to be equipped with relevant theoretical and practical skills that provide a sound foundation in this discipline. This case study was undertaken to gain a better understanding about how the participating teachers perceived and implemented the Agriculture curriculum at the senior secondary school level in their schools. In carrying out the case study a qualitative research method was employed using semi-structured interviews, observation and document analysis for data collection. It would appear from this study that Agriculture is unable to fully achieve the reform ideals at the senior secondary school level, as sixteen years after independence these teachers are still teaching the subject to learners with very limited resources and academic support. This scenario shows that there are marked inconsistencies between policy and praxis, between the stated goals and aims of the reform and the curriculum designed to achieve these. In this half-thesis I therefore argue that without well qualified teachers, suitable resources and infrastructure to implement the curriculum in these schools, the pre-vocational nature of the subject as suggested in the subject policy document will be compromised. The study concludes by proposing certain teaching strategies and possibilities for systemic development that can be used to effect quality curriculum implementation in the region where the research was situated.

- Description: Introduction: Process analytical technologies are systems for the analysis and control of manufacturing processes to assure acceptable end-product quality. This is achieved by timely measurements of critical parameters and performance attributes of raw material and in-process material and processes. The introduction of process analytical technology using near infrared analysis was investigated in three areas, namely incoming raw material analysis, blend uniformity analysis and moisture determination in the fluid bed dryer. Methodology: Incoming raw material identification - The FOSS XDS rapid content analyzer was used for the development of a NIR method for the identification and material qualification of starch maize and lactose monohydrate. Blend uniformity analysis – The SP15 Laboratory Blender fitted with near infrared probe was utilized for the study. Two types of blend experiments were designed to monitor the distribution of magnesium stearate (lubricant) in the blend, namely, a powder blend utilizing lactose monohydrate and a granule blend utilizing Ridaq® granule. Software methods were developed to monitor the standard deviation of the absorbance at the wavelengths that were specific for lactose monohydrate, Ridaq® granule and magnesium stearate. To confirm the prediction of end-point using near infrared, results were verified using an atomic absorption method for magnesium stearate. The blends were sampled at the selected time intervals corresponding to three states of the blend, namely, before end-point, at end-point and after end-point using a sampling plan. An additional six blends were conducted for the granule blend and sampled when the standard deviation had reached a value below 3 x 10-6 at the magnesium stearate wavelength at four consecutive data points (standard deviation value extrapolated from blends carried out to predetermined time intervals). Moisture determination in the fluid bed dryer – Moisture values for two products (Product A and Product B) were retrospectively collected from past production batches. A process capability study was conducted on the moisture values to determine if the current process was in a state of control. Results and Discussion: Incoming raw material identification – The algorithms used for the spectral library were able to distinguish between the raw materials selected. The spectral library positively identified the starch maize and lactose monohydrate samples that were not present in the library. The negative challenge with pregelatinised starch and tablettose demonstrated that the spectral library was able to differentiate between closely related compounds. Blend uniformity analysis – Blends sampled at the predetermined time intervals demonstrated a homogeneous state when the standard deviation of the absorbance was low and a non-homogeneous state when the standard deviation of the absorbance was high, thus near infrared prediction on the state of the blend was confirmed by the standard analytical methods. The series of Ridaq® granule and magnesium stearate blends sampled when the standard deviation was below 3 x 10-6 were homogeneous with the exception of one blend that was marginally out of specification. Blend durations were significantly lower than the standard blend durations used in the facility and ranged from 112 to 198 seconds. Moisture determination in the fluid bed dryer – From the process capability study of the two products it was noted that Product A is stable but can still be optimized while Product B is at a desirable state. The statistical evaluation of the moisture values for Product A and Product B demonstrated that the use of the product temperature to monitor the moisture gave consistent results. The current process is stable and capable of producing repeatable results although near infrared provides a means for continuously monitoring the product moisture and allows one to take action to prevent over-drying or under-drying. Conclusion: From the investigations conducted, it can be seen that there is definitely a niche for process analytical technology at this pharmaceutical company. The implementation is a gradual process of change, which may take time, probably several years (Heinze & Hansen 2005).

- Description: The use of Computer Aided Software Engineering (CASE) tools for teaching object-oriented systems analysis and design (OOSAD) has many potential benefits, but there are also several problems associated with the usage of these tools. A large portion of these problems relate to the usability and learnability of these tools. Learnability is one of the most important attributes of usability and refers to the capability of the system to enable the user to learn its application. The main research question that this study aims to address is “How can the learnability of OO CASE tools for computing education in South Africa be evaluated?”. In order to answer this question several frameworks for evaluating CASE tool usability and learnability were investigated. One of these frameworks, as proposed by Senapathi, was selected as being the most appropriate for evaluating CASE tool learnability for computing education. This framework maintains that the learnability of a CASE tool is dependent on context of use factors such as the tool used, as well as user characteristics such as gender. The primary aim of this research was thus to validate Senapathi's framework for CASE tool learnability in a South African context. A secondary aim of the research was to extend the implementation of the framework in order to enable the comparison of two CASE tools and to support the inclusion of other user characteristics. An experiment was performed at the Nelson Mandela Metropolitan University (NMMU) in 2006. The participants recruited for this experiment were second year computing students at NMMU. During this experiment, the learnability of two OO CASE tools, namely IBM's Rational Software Modeller and Microsoft's Visio, was evaluated and compared. The quantitative and qualitative results supported Senapathi's results and showed that her framework could be used to evaluate CASE tool learnability and could be adapted to evaluate two CASE tools. The results also showed that the majority of the participants rated the learnability of Microsoft Visio higher for both tasks and that the main reasons participants preferred Visio was due to its simplicity, familiarity and recoverability.

- Description: Plant diseases caused by fungi are the number one cause of crop loss worldwide. The application of a fungicide which is a toxic substance applied either to prevent the growth of, or to kill fungi is one of the methods by which plant diseases are controlled. Ethylenebisdithiocarbamate fungicides are a group of surface acting fungicides which control a broad spectrum of fungi and their associated plant diseases. Mancozeb, also commonly known as Dithane, falls under the polymeric Dithiocarbamate fungicides which have several sites of toxicity to the fungal cell. The use of Mancozeb as a fungicide is increasing worldwide due to the advantages of low acute toxicity, low production and short environmental persistence. However, it has one major disadvantage, namely its lack of oxidative stability under ambient conditions. One of the objectives of this study was to characterize the Dithane samples supplied by Dow AgroSciences in terms of their active ingredient, metal and stabilizer content, and to study the thermal decomposition behaviour of Dithane. An attempt was made to correlate the active ingredient analyses with the TGA and DSC results to establish whether the thermal stability and active ingredient content of Dithane could be simultaneously determined by thermal analysis. This approach offered the attractive advantage of shorter analysis times thus allowing the elimination of the more tedious analytical methods employed by Dow AgroSciences. Furthermore, Fourier Transform infra-red characterization of Dithane samples and metal complexes containing HMT, Mn and/or Zn was carried out in order to identify the presence of functional groups and to gain some insight into the nature of the bonding of HMT, sulfate and water. A study of the nature of the bands in the FTIR spectra of these complexes was able to highlight the nature of the bonding but could not give confirmation of the structures of these complexes. In addition to this, the amount of HMT present in the said complexes was determined by the FTIR using the standard addition method. A final objective of the study was to investigate the reconstitution of Dithane by investigating the influence of the addition order of the various constituents on the stability of the final product. The addition order was found to have a definite influence on the thermal stability of the final product as well as on the percentage of fixed HMT in the product, and the kinetics of the Mn/Zn exchange.

- Description: The study set out to investigate the perceived effects of the Leadership Development Programme, a two-years training programme for school principals in the Ondangwa East Educational Region of Namibia. The objective has been to find out whether the training curriculum and content were related to what participating principals thought they needed to help them to do their work better, and improve their schools. Data were collected through interviews with two of the first group of nine principals who have completed the training. The study has found that the Leadership Development Programme helped the participating principals to experience personal changes and professional growth. Through the process of participatory action research, the Leadership Development Programme has been able to bring together theory and practice. It has also helped the principals to recognize their responsibility for planning, implementing and evaluation of action, and problem solving initiatives in their schools. The study has also found that the Leadership Development Programme recognized, and therefore applied, the element of experiential/adult learning. Although the Programme has had its basic core curriculum, its content and training process have been flexible in the sense that the Programme tried first to establish what participants knew, and then assisted them to gain a new and enquiring perspective on their knowledge and practice, which helped them to become reflective practitioners. While the study could not establish with a degree of certainty as to what extent the principals have taken up the processes of the training Programme in their schools, it has, however, found that there are many positive changes brought in about schools during the time the training was running. Secondly, while the study could obviously not establish a direct link between every change and the inputs made by the training Programme, it concluded, however, that the Programme at least brought about changes in the mindsets of principals, which were conducive to teaching and learning. What was important, though, was the question of how many of the initiatives were still bearing fruit three years after the training has taken place.

- Description: Motivated by a concern as to why Zambians are attracted to foreign media in the form of Nigerian movies, this thesis is a qualitative audience study which investigates the popularity of Nigerian movies in Zambia with a focus on Lusaka viewers. Against the dominance of Western media and most especially Hollywood movies, this study explores the popularity of Nigerian movies in Zambia which highlights the circulation of media within and between non-Western countries. This is an aspect of trans-national cultural flows that has been ignored in theories of media imperialism. The thesis argues that the widespread popularity of Nigerian movies in Africa and in Zambia in particular necessitates a revision of the conceptions of global cultural flows that privilege the centrality of the West but ignore other centres engaged in contemporary cultural production.

- Description: The development of the tabloid press has stirred heated debate among media scholars. Critics have argued against the relevance of tabloids in society, often framing them as the ‘journalistic other’ deserving no place in ‘serious’ journalism. Much of this criticism, however, has not been based on a close interrogation of the phenomenon, or an examination of the reasons for their popularity amongst readers. It is against this background that this study investigates the reasons behind the popularity of the Zimbabwean state-controlled tabloid newspaper uMthunywa, among its Bulawayo readers. In particular, it explores the meanings obtained from the content of the paper and the relevance of this content to the readers’ everyday lives. In undertaking this investigation, the study draws primarily on qualitative research methods, particularly qualitative content analysis and in-depth interviews (both group and individual). As the study demonstrates, these methods uncover the complex manner in which Bulawayo readers are attracted to uMthunywa and how they appropriate its textual meanings to their lived realities. The study establishes that despite uMthunywa being state-controlled, it offers space through which the conventional ways of presenting reality are challenged, and the importance of the newspaper being written in isiNdebele. As the study indicates, the popularity of the newspaper is largely dependent on its excessive formulaic and sensational stories, which cover issues experienced by its readers in their lived circumstances. The study thus argues that the newspaper constitutes an alternative mediated public sphere that finds space in the deeper social conditions that have alienated the people of Bulawayo from the macropolitical life of the nation and the ‘power bloc’.

- Description: This study investigates the representations of women in advertisements featured in South African Cosmopolitan magazine published in 2004 so as to critically analyse the stereotypes of women it presents, the institutional mechanisms behind this and its implications for gender ‘constructions’. By using a random cluster sample, 60 advertisements found in Cosmopolitan were analysed to examine the stereotypical portrayals of women within its imagery. In addition, survey questionnaires were distributed amongst female students to determine whether exposure to advertisements featured in Cosmopolitan magazines moulds their thoughts with regard to South African women today, as well as to analyse their attitudinal change before and after exposure to a number of advertisements. It was found that even though the majority of respondents claimed to be aware of the stereotypical representations of women found in the advertisements, and did not believe that these portrayals were a true reflection of South African women, various aspects of their lives continue to be affected by these representations in a number of ways. The findings of this study indicate that the trend found in previous studies – that stereotypical images of women prevail in the media – is evident in South Africa too. It was established that the ideologies of both patriarchy and capitalism work together in supporting the pervasiveness of negative, disempowering portrayals of women in Cosmopolitan advertisements. Stereotypical imagery of women serve as the site at which the ideologies of capitalism and patriarchy fuse, drawing on a common, shared notion of the objectified female to further their goals of maximisation of profits and male dominance respectively.

- Description: South Africa has experienced significant curriculum transformation over the past ten years. Environment was introduced into C2005 as a phase organiser. Following the streamlining and strengthening of the curriculum, the National Curriculum Statement (NCS) has a more explicit environmental focus in all of the Learning Areas. This has created opportunities for teachers to address environmental health issues in a community context. I work in a rural school and the community around the school experience a number of environmental health issues. In my previous observations I noticed that teachers were not using Learning Teaching Support Materials (LTSM) effectively. In this study I wanted to investigate how LTSM can be used to address environmental health issues in the Foundation Phase. As Life Orientation Learning Outcome1 is a ‘backbone’ of the Life Skills Learning Programme in the Foundation Phase, I decided to focus on this Learning Outcome as it is the Health Promotion outcome in the NCS (R-9). It was my interest to investigate how LTSM are used in team planning and how this planning influences the use of LTSM in classrooms. In the research I observed the link between the activities and LTSM that were discussed in the planning session and those that were done in the classroom. To do this I documented the planning workshop, and I also observed three lessons undertaken in two classrooms, a grade 2 and a grade 3 classroom in my school, where I serve as a principal. I conducted this research as an interpretive case study, and I used workshop, interviews, focus group interviews and classroom observation as methods in the study. The study found that LTSM used in planning influences activities done in the classroom. It also found that use of LTSM helps to achieve the Learning Outcomes and Assessment Standards, and to improve the participation of learners in the learning process. Use of LTSM in planning also improves teachers’ Learning Area knowledge and their knowledge of curriculum development issues. Planning sessions also assisted teachers to address problems such as language used in LTSM and availability of LTSM. The study also found that teachers did not address formal assessment in the planning or in the way they used LTSM. The study concluded that use of LTSM in planning can strengthen classroom practice, and recommendations were made to take this work forward in the context of our school, as it addresses the gap between policy and practice.

A case study was conducted within the interpretive paradigm. Six School Board members from the selected school were interviewed. The data were analysed using qualitative data analysis practices. The findings of the study indicate that there are numerous constraints that interfere with the Board members' ability to effectively carry out their role as a school governing body. These constraints include a lack of knowledge and understanding of the Education Act, a lack of skill in conducting basic management and organization processes and a lack of support from the circuit inspector and Regional Education officers. This study provides some understanding of the circumstances of the School Board in trying to execute its role in implementing the Education Act, especially the section dealing with School Boards. As such, this research provides an agenda for the support and improvement of the work of School Boards in Namibian secondary schools.

- Description: Poverty alleviation by means of rural development has become a priority among developing countries. In turn, rural development may be significantly enhanced and supported by Information and Communication Technologies (ICTs), the use of which is highlighted by the emerging importance of information and knowledge as key strategic resources for social and economic development. An analysis of rural case studies where ICTs have been introduced, suggests that there are a number of barriers and constraints that are faced when taking advantage of these technologies. These include access to infrastructure, limited formal education, insufficient training and capacity building, financial and political constraints, and social and cultural challenges. These challenges threaten the success and sustainability of rural ICT projects. Sustainability is key to the effectiveness of a rural ICT project; therefore it is important to understand the concept and categories associated with ICT project sustainability in rural areas. The categories of sustainability which include social and cultural, institutional, economic, political, and technological, reveal critical success factors that need to be considered in the implementation and management of rural ICT projects. The project management discipline acknowledges the importance of understanding the project’s environment, particularly environmental factors associated with rural communities. The complexity of the environment therefore implies the need for a project to be undertaken in phases comprising the project life cycle. Project management practice for rural ICT project sustainability can therefore be examined, adapting the traditional project life cycle to a rural ICT project. A Rural ICT Project Life Cycle (RICT-PLC) that is sensitive to the critical success factors of sustainability is therefore proposed. In order to further investigate the phases of the life cycle of a rural ICT project, two case study investigations are explored: the Dwesa ICT community project, and the Rhodes University Mathematics Education Project (RUMEP) (MathsNet). A multiple case study analysis confirms the practices associated with the RICT-PLC model, and identifies additional characteristics, phases and practices associated with rural ICT projects. Finally, an enhanced RICT-PLC model is developed, that sets sustainability guidelines for ICT project management in rural areas and identifies the people, environments, technologies, systems, and requirements for ICTs to support rural development activities.

- Description: Over the last several years studies have shown that the quality of indoor air may be worse than outdoor air. People spend as much as 90% of their time indoors, therefor, the associated health risk due to indoor air pollution may be greater than the risk due to outdoor air pollution. Building designs have altered dramatically over the last two decades resulted in "tighter" buildings that rely on sophisticated mechanical systems to provide for the quantity of air required throughout the building. These changes over the years could result in an increased number of complaints received regarding Sick Building Syndrome symptoms. The World Health Organization (WHO) estimates that up to 30% of office buildings world-wide may have significant problems regarding poor indoor air quality (IAQ). This study involves a literature study of the major indoor air pollutants regarding the source of the pollutant, the associated health effects, the measuring techniques available and the results of previous studies conducted on the specific pollutant. Measurements will be taken in two sealed buildings, one an old and the other a new building to identify the major pollutants. A questionnaire was compiled specifically for building occupants and completed by the occupants of both buildings. From the results obtained a step-by-step method for solving indoor air quality (IAQ) problems was proposed. The method was applied and evaluated in a case study of a problem building where indoor air quality related problems were experienced. The results of the study revealed that the major indoor air pollutants are present in old as well as new buildings. The study also revealed that some office workers might be more susceptible than others to the medical reactions cause to human beings by these pollutants. Some concentrations are higher in new buildings than in old buildings. The responses from the questionnaire was evaluated against the results obtained from the measurement study. The step-by-step method in the case study provided a more systematic approach at solving IAQ problems at buildings. Solving indoor air quality problems is a very practical issue and does not necessarily require an investment of expensive high technology equipment, but might merely require a practical approach. Environmental Health Officers can play a major role in providing expert advice when scrutinizing building plans. Environmental Health Officers should empower themselves with the knowledge to do inspections or investigations in office buildings by using the step-by-step method for investigating indoor air quality problems. By addressing indoor air quality problems in buildings, the workers in healthy buildings can increase their productivity with lasting effects on a company’s bottom line.
