- Description: Information is a critical asset in any organisation and its management, including the associated technological channels, requires the attention of decision-makers to ensure that information assets are utilised for the intended purposes. Therefore, decision-makers need to have appropriate governance oversight on technology that produces information and information itself. Over the years, the governance of ICT has been adopted in the public sector given the fact that state funding received from tax collections is utilised to invest in IT solutions with the intention of expediting service delivery and increase productivity. The purpose of this treatise was to identify the root causes of why the department is not implementing Corporate Governance of ICT successfully despite the fact that most good controls do exist. The research revealed that there is insufficient budget to implement ICT projects coupled with inadequate ICT staff to implement ICT strategy. Furthermore, it cited a lack of ICT governance skills with ICT Strategic Committee members who are tasked with pioneering ICT governance. This weakness relates directly to other identified weaknesses such as end-user resistance to adopt ICT projects and a lack of project management function in the department.

- Description: The purpose of the study is to explore and describe challenges experienced by health professionals regarding implementation of the referral system used in Buffalo City Metropolitan Municipality (BCMM) in the Eastern Cape Province. A referral system in health care can be defined as a method whereby a health worker with insufficient skills and less resources in the primary health care setting, who has fewer remedies or options to manage medical conditions, seeks assistance from a more senior practitioner in a tertiary setting with better resources to provide guidance in managing the patient or to take over the management of the patient (Eastern Cape Department of Health, 2007:7). A qualitative descriptive explorative contextual design was used to explore and describe the challenges pertaining to the implementation of a referral system in the public health sector in Buffalo City Metropolitan Municipality (BCMM) in the Eastern Cape. A purposive sampling technique was employed with an inclusion criteria of health care professionals who are doctors, professional nurses, pharmacists and specialists. After obtaining ethical clearance from the respective departments, steps for data collection were implemented. Individual interviews were conducted using an interview guide that was prepared by the researcher. Findings in the study indicate that there are challenges in implementing a referral system in relation to infrastructure, workforce capacity, equipment, transport and drug availability. The participants provided suggestions according to their experiences on what they felt the Department of Health in BCMM could do to strengthen the referral system in place. The researcher then provided recommendations to the Department of Health of BCMM. The health referral system in BCMM needs to be strengthened through provision of adequate infrastructure, improving workforce capacity, and availability of medicines and equipment. A monitoring and evaluation plan must be affected by the Eastern Cape Department of Health. Education and training are needed for the health care workers and the community through their involvement in stakeholder meetings

- Description: In the major cities of South Africa, there is a prevalence of originally built commercial buildings that are being converted into residential apartments or other industrial economic spaces. These secondary users refurbish the original structures to accommodate their new specialised requirements and this mostly happens after the buildings have been lying vacant for a long period of time. The study by Y.Long et al. (2011) narrates the changes in land use, identification of driving forces and the mapping of areas that are experiencing intense land use transformation. Properties that were developed for a focused particular use, were found to have been redeveloped within a few years for other functions. Subjects that were included in the sample were selected to meet specific criteria. The stakeholders had to meet the following criteria to be included in the sample: They were registered professionals in the built environment such as: Architecture, Engineering (civil, electrical, mechanical and structural), Quantity Surveying, Town Planning, Construction Management and Estate management The method that was used to collect data was self-completion questionnaire that was given out by electronic mail. After the data was collected, it was organised and analysed. For the analysis of closed-ended questions, an online programme called QuestionPro, was used, data was analysed by using descriptive statistics and frequency tables were drawn and from these, the data was presented in pie diagrams and bar graphs. While it is necessary to expand the horizons of the ever-growing global population, it is imperative that all stakeholders in the building industry work together to find sustainable solutions to residential and industrial development.

- Description: People who have been diagnosed HIV positive often experience distress and anxiety due to uncertainties pertaining to the implications of an HIV positive status. Research has shown that support groups have always been a way for people to cope with the distress and stressful circumstances associated with health conditions such as HIV. This research investigated the role of face to face support groups in the lives of those living with HIV. The primary focus of this research project is to provide an in-depth exploration of HIV positive individuals‟ experiences of being in a support group. The study aims to explore the positive and negative experiences of being in an HIV support group and aims to gain an understanding of the role support plays in the lives of those living with HIV. A qualitative research design was used to explore the above mentioned aim. Semi-structured interviews were conducted with five individuals, (three women and two men) who had experienced HIV support groups. The interviews were transcribed and then analysed according to the principles of interpretative phenomenological analysis (IPA). The findings of this study revealed five super-ordinate themes, which revealed not only the positive and negative experiences of being in a support group, but also the challenges that the participants‟ experienced before joining the group. Getting a sense of the participants‟ experience before joining the group allowed the researcher to get a better understanding of how useful or not the support group has been in helping them deal with the challenges of living with HIV. The themes included: „struggling to survive after diagnosis‟, „struggling to cope: adopting negative coping skills‟, „experiencing a turning-point: a will to survive‟, „attending support group: a sweet experience‟ and lastly, „attending support groups: a bitter experience‟. Findings suggest that for these participants, the advantages outweighed the disadvantages of being in a support group. Therefore this study suggests that face to face support groups are a viable and even necessary option for support. These findings support previous research and literature in regards to the importance of social support in the form of support groups in effectively assisting HIV positive people in their journey to adjust to the consequence of living with HIV.

- Description: Indigenous forests along the Wild Coast of the Eastern Cape Province have experienced both degradation and deforestation over the past decades. In early 2000, steps were taken to rehabilitate some of the degraded areas. Nevertheless, there is no monitoring mechanism in place, so little is known about the extent of degradation and impact of the rehabilitation efforts. The present study assesses the extent to which deforestation and degradation of the indigenous forests have occurred, and evaluates rehabilitation efforts in the study area around Port Saint John’s. Forest degradation was defined as the decrease in forest cover density while deforestation was defined as an increase in the trend of light forests and/ or a decrease in dense forests. The details for this study were obtained from multi – temporal remotely sensed data for a period between 1982 and 2013 (31 years). Multi-temporal Landsat satellite imagery for 1982, 1986, 1989, 2002, 2009 and 2013 was acquired and analysed. On the basis of prior knowledge of the area, the supervised classification approach was used. The Maximum likelihood supervised classification technique was used to extract information from satellite data. The classified images were filtered using a majority filtering procedure to reduce noise. Google Earth (Astrium) ancillary images were used to refine the classification based on expert rules. The derived changes in the degraded and rehabilitated areas were further validated through field visits. The overall image classification accuracy generated from Landsat image data ranged from 80% to 90%. It was noted that the area of dense forest almost doubled between 1986 and 1989, coinciding with a 59% decrease in the light forest. Subsequently, dense forests increased by 14,820 ha while light forests decreased by 16,690 ha between 1989 and 2002. The subsequent reduction in light forest coverage is explained by the establishment of the Participatory Forest Management (PFMA) approach by Department of Water Affairs and Forestry (DWAF) which reversed the degradation trend. However, specific degradation hotspots were identified, particularly where new settlements have been established. The emergence of the non-vegetated area increased gradually from 7% in 1986 to 23.4% in 2013. Notably, dense forest was observed to have experienced higher rates of forest degradation and deforestation than the light forest. The highest number patches were 4 recorded between 2002 and 1998, followed by between 2010 and 2013 and lastly 1986. Based on spatial connectedness of patches, the year 1986 had the highest landscape connectedness of forest vegetation (CONAT = 35.3) followed by 2002 and 1996 while the year 2010 and 2013 had the lowest landscape contiguity. Over the study period, the distribution of patches clearly shows that forest degradation and deforestation rates were lower in the years 1986, 1998 and tremendously increased in the later period of between 2010 and 2013. However, as a result of rehabilitation efforts, dense forest was seen to steadily gain more land than light forest. Finer details of degradation trends could not be easily picked from the images used in the study, given their spatial resolution limitations. That notwithstanding, the trends identified are good for overview decisions. The study has also established that de-agraianisation, forest restoration and rehabilitation greatly contributed to increased forest cover. Therefore, with more use of GIS by forest managers, and imagery of the high resolution being readily available, forests will in future be easily monitored using remote sensing.

- Description: South Africa is characterised by high levels of HIV infections and unwanted pregnancies, despite the vast amount of interventions aimed at combatting this issue. It becomes important to explore why these interventions are not actively achieving what they aim to. A major cause for concern is the increase in risky sexual behaviour in the adolescence and young adult (15-24 year) age group. In various cultures, women’s socialization has a direct impact on their ability to prioritize their sexual health. Steeped in patriarchal ideology, many South African cultures prioritise the power of masculinity over and above the femxle experience. Improved partner communication leads to decreased risky sexual behaviour, but it becomes tricky when the relationship is characterized by a gender power imbalance. This study is aimed at understanding South African femxle sexual health by focussing on 1) the extent to which the overarching traditional beliefs about femininity is related to their sexual self-efficacy. Furthermore, it is aimed at 2) the extent to which they engage in sexual activity and behaviour that would protect them from STIs and unwanted pregnancies. Research design is quantitative and include an online survey for femxle students between the ages of 18 and 24, enrolled at the Nelson Mandela University, South Africa. The data was analysed statistically, where after the research findings will be interpreted from the perspective of Feminist Psychological Theory.

- Description: This study explores social entrepreneurship projects which are specifically run by the youth in an attempt to mitigate poverty and unemployment in the Amathole District Municipality, Eastern Cape. It also evaluates the extent to which selected social entrepreneurship interventions have contributed to employment creation and income generation. Furthermore, not only does the study investigate social entrepreneurship opportunities available for rural youth in Amathole but goes further to evaluate the sustainability of existing social entrepreneurship projects. The challenges faced by rural youth in pursuing social entrepreneurship are also explored. In so doing, the study is underpinned by the Positivist Youth Development (PYD) theory. The study found that the youth of Amathole District Municipality have a positive attitude towards social entrepreneurship. They engage in a variety of social enterprises. However, the youth face many constraints such as lack of access to finance, lack of business skills, lack of entrepreneurial education and lack of technical support. All these constraints are interrelated and lead to issues of unsustainability and limited income generation and employment creation. Informed by these constraints, the study recommends coordinated awareness campaigns and government (national/provincial) response about social entrepreneurship and community needs within Amathole. To further understand social entrepreneurship, there is need for further studies to investigate the attitudes and constraints of women towards social entrepreneurship as well as youth’s understanding of social entrepreneurship in general.

- Description: With the continued miniaturization of technology and the incorporation of Moore’s law, smartphones are more powerful. These mobile devices contain technologies that add other functionalities to them. Technologies such as sensors constantly provide information to the device. The constant stream of information from these sensors often leads to information overload of relevant and irrelevant information. To work towards solving this problem context-aware computing was introduced. Our major concern is that context information in context aware computing is not completely being utilized. The aggregation of context information could unlock more possibilities. This research seeks to aggregate the context of multiple devices such that, through analysis, some emergent behaviour can be observed. In this research context information from the sensors of devices is collected using an Android application and a central Server. The context information is used for pattern analysis. A pattern analysis algorithm is designed and used to observe patterns throughout the data set. It shows patterns that are similar within the dataset. In the case that the pattern observed has no similar pattern or few similar patterns this behaviour can be stated as emergent in the dataset. Further study of this emergent behaviour can be performed were a classifier can be used to give the exact activities that were being performed at that time. The research found this was possible and has many uses. One of these is in disaster prevention were the behaviour of a group of individuals may be monitored to observe any random changes such as masses running at the same time. This could be used as a first warning to natural disasters.

- Description: The South African Nursing Council requires registered nurses to have the necessary knowledge, skills, attitudes and values which will enable them to render an efficient service (Morolong and Chabeli, 2005:39). The South African Education and training system, through its policy of outcomes- based education and training, has tabled competency as a national priority. In support of this, the South African Nursing Council (SANC) requires that the newly qualified registered nurse possess competency on the core functions of a registered nurse. The health system also demands competent nurse practitioners to ensure quality nursing care. Due to the fact that competency is a national priority and a statutory demand, the research question that guided the study is what are the perceptions of unit managers regarding competencies of newly qualified registered nurses in East London Health Care services. The study was aimed at describing the perceptions of unit managers regarding the competencies of newly qualified registered nurses in order to propose the recommendations to improve the competencies of such newly qualified registered nurses and to provide quality patient care. A quantitative descriptive non experimental design was used to evaluate the perceptions of unit managers regarding competencies of newly qualified registered nurses from a public nursing college. The sampling method of probability convenience sampling was used in this study. Data were collected by means of a questionnaire administered to ninety unit managers and only eighty one unit managers participated in the study. Data were analysed using the Statistical Package for the Social Sciences (SPSS) version 22 software. Statistical methods enabled the researcher to reduce, summarize, organise, manipulate, evaluate, interpret and communicate quantitative data. Data were cleaned and coded and spoilt data were checked. Findings from the software were displayed in graphs or tables. Concerning the eighty one unit managers who participated in the study, age and sex matched respondents were selected according to their availability.The results showed that there is agreement that competence of the nurses affects the image, mission and staff utilisation in their units and/or institutions. There was no dominant opinion on the possible association between competency and environmental, physical and technological factors. There was unanimous agreement that newly qualified nurses need constant supervision and in-service training. There was moderate agreement on the use of acquired knowledge and skills by nurses and there was no dominant opinion about how newly qualified nurses tolerate differences and handle misunderstandings and shortcomings of other professions. In conclusion newly qualified registered nurses need coaching, mentoring, n-service training and constant supervision. Recommendations regarding strategies to be used to improve competencies of newly qualified registered nurses included exit evaluations of community service practitioners, stipulating the competency framework of newly qualified nurses and assessment criteria of competency. Mentoring and coaching of newly qualified registered nurses during community service, monthly or quarterly meetings with the community service candidate in order to identify their challenges were also recommended. Motivation strategies in order to boost their morale so that they can deliver quality patient care. The newly qualified registered nurses should hold meetings with the unit managers regarding the challenges the unit managers face when assessing competencies of newly qualified registered nurses.

- Description: This study shows a detailed report on the morphological, structural and optical properties of CdSe QDs synthesised by the hot injection method. Cadmium acetate dihydrate and Se powder were used as cadmium and selenide precursors, respectively. Various QD sizes were achieved by synthesizing in temperature range of 150ºC, 175ºC, 200ºC, 225ºC, 250ºC, 275ºC and 300ºC, respectively. The as synthesized QDs by the hot injection method were cross-examined for their morphological, structural and optical using HRTEM, FTIR, XRD, RS, and UV-Vis spectroscopy techniques respectively. FTIR analysis has revealed vibrations at 738, 738, 738, 738, 735, 735 and 733 cm-1 for the QDs synthesized at various temperatures of 150, 175, 200, 225, 250, 275, and 300℃, respectively. The presence of the above mentioned peaks confirms the presence of Cd-Se bond in our samples. XRD analysis of CdSe QDs revealed diffraction peaks at 2 angles of 16.66 , 25.20 , 34.77 , 40.9 , 45.39 and 49.1 for 150 17.4 , 25.22 , 34.85 , 41.7 , 44.45 and 47.5 for the QDs synthesized at various temperatures of 175 17.07 , 25.19 , 34.85 , 41.34 , 44.41 and 48.86 for 200 ; 16.34 , 25.20 , 34.76 , 40.6 , 44.74 and 49.48 for 225 ; 17.44 , 25.17 , 34.19 , 41.7 , 44.45 , 49.24 for 250 ; 16.70 , 25.16 , 34.85 , 40.32 , 45.1 and 49.1 7 for 275 ;and 17.35 , 25.18 , 35.13 , 41.63 , 45.7 , 49.48 for 300 . These XRD peaks relate to crystal planes of (100), (002), (102), (220), (103) and (112) which belong to hexagonal Wurtzite CdSe crystal structure. Additionally XRD analysis has revealed a general peak shift to higher 2 values was observed for CdSe QDs. HRTEM analysis showed that the synthesised CdSe QDs have a spherical shape and are monodispersed. Moreover, HRTEM analysis has revealed CdSe QDs modal crystallite size of 1.79 nm, 1.81 nm, 2.06 nm, 2.08 nm, 2.11 nm, 3.10 nm and 3.12 nm for the QDs synthesized at various temperatures of 150ºC, 175ºC, 200ºC, 225ºC, 250ºC, 275ºC and 300ºC, respectively. HRTEM results were in mutual agreement with XRD results. Additionally, the SAED images showed intense electron diffraction rings, which confirmed that the as-synthesised CdSe QDs have a Wurtzite crystal structure. RS analysis showed that CdSe QDs have LO and 2LO vibrational modes which are characteristic peaks for CdSe. The presence of these peaks in Raman spectra further supports our previous observation from XRD analysis and HRTEM analysis that the synthesized CdSe QDs have a Wurtzite crystal structure. The effect of synthesis temperature Raman peak shift, FHWH and peak intensity has been cross examined in this work, Moreover, the effect of increasing temperature on the peak shift, FWHM and peak intensity is discussed in detail below. UV-Vis analysis revealed an absorbance of CdSe QDs in higher wavelengths as temperature was increased. Furthermore, the Yu et al 2003 relation was used to calculate QD size and band gap energy of CdSe QDs. The results showed that QD size increases with increasing synthesis temperature, which is in agreement with HRTEM and XRD results.

“I am 22 Million”: reading Winnie Madikizela as the intellectual face of anti-apartheid popular struggle

- Description: The purpose of this research is to read Winnie Madikizela Mandela as an intellectual. Through this research I want to examine whether Madikizela Mandela emerges from an intellectual tradition influenced by the political and intellectual discourse that existed at the time within the country such as the ideology of the African National Congress (not to say that this was without external influence but I would argue that the ideology of the ANC evolved to fit the domestic politics of the day), the Civil Rights Movement, the Black Panther Party and Black Consciousness. Through trying to understand Madikizela Mandela’s intellectual journey this thesis will explore the larger question of intellectual production. Lewis Gordon argues that it is often presumed that theory is north and experience is south.1 As a result black people are often excluded from being possible intellectuals and shapers of intellectual discourse but are rather relegated to the categories of ‘actors’ rather than thinkers. The point of departure of my research will be through Winnie Madikizela-Mandela’s image as it provides a clue into the type of intellectual influences and ideologies that she subscribed to. This flows from Charles R. Garoian and Yvonne M. Gaudelius’ “The Spectacle of Visual Culture” where they argue for images teaching us what to see and think.2 Winnie Madikizela Mandela was a frequently photographed person and it is through these images that we witness an evolution in the way she presented herself which, as this research argues, is influenced by certain intellectual traditions that guide the black liberation struggle. In What’s My Name: Black Vernacular Intellectuals, Grant Farred explores the role of clothing in the conveying of intellectualism influenced by a certain ideology. Therefore I argue that Winnie Madikizela’s iconicity is more than conventional standards of beauty, or her link to her husband Nelson Mandela. It is rather a tool that she uses to convey an ideology and this complements that which she says when she chooses to speak.

The study used the qualitative design. Data was collected using in-depth interviews in which twenty individual participants took part. The results indicate that the challenges of SAP child protection unit in providing services to vulnerable children in Alice, Eastern Cape Province are mainly financial based, emotionally stressful, labour related, and can be caused by parental oversight, legal constraints that begets lack of trust and also policing illegal child immigrants. These factors make the police child protection unit’s work challenging thereby hampering its effectiveness. It has therefore been recommended that the police child protection unit should be given the support due to them so as to make service delivery to vulnerable children in Alice effective. Also it has been recommended that children be educated that the police are there to enforce the law, assist and not to harm them.

This fabric plays a vital role in contributing to the collective significance and character of a place, despite its comparatively less remarkable nature. These buildings are often most susceptible to change, especially with regard to use. Responsible conservation and innovative design can allow buildings to undergo inevitable change, without compromising their heritage significance, despite the increasing demands of contemporary urban building typologies. Office typologies of the 21st century are particularly demanding with regard to efficiency, flexibility, sustainability and the need for a creative environment that promotes collaboration among knowledge workers. The document sets out a process by which to sensitively manage the juxtaposed relationship between historic buildings and a contemporary use, to generate an innovative design, resilient in its ability to retain the historic meaning of existing buildings.

- Description: Whilst the concept of teacher leadership is not new in the international literature (Grant, 2006), research on the topic of teacher leadership is emerging slowly as a new area of research interest in South Africa (Grant, 2006; Grant, 2005; Singh, 2007). Teacher leadership is basically about teachers who are leaders within and outside the classroom, who identify with and contribute to a community of teacher learners and leaders, influence others to improve their teaching practice and accept responsibility for realising the goals of their organisation (Katzenmeyer & Moller, 2001 in Grant, 2006). Therefore, teachers’ roles in operating as leaders in schools are acknowledged in literature. This study is a replication of a University of KwaZulu-Natal multi-case study on the enactment of teacher leadership conducted in various educational institutions in the province of KwaZulu-Natal. In line with the original study, this study aimed at obtaining an understanding of the enactment of teacher leadership in a township high school in the King William’s Town education district, in the Eastern Cape. I further explored what factors promoted or hindered such enactment. As an Eastern Cape Master of Education student participating in a group research programme at Rhodes University, we adopted and used the same research questions, research approach, data collection methods as well as data analysis techniques as utilised in the original study. Therefore, this research study was conducted within the interpretive paradigm, following a qualitative approach. I adopted a case study methodology, with the case being the school and three teacher leaders as units of analysis. Data were gathered through a multi-method approach which consisted of a school profile, a focus group interview, semi-structured individual interviews, questionnaires, self reflective journaling and observations. Whilst the research was guided by distributed leadership theory, Grant’s (2008) Model of teacher leadership and thematic content analysis was used to analyse data. Research findings revealed that the enactment of teacher leadership was evident in Zones 1, 2 and 4 of Grant’s (2008) Model of teacher leadership in the case study school. However, a restricted form of teacher leadership was enacted in Zone 3, whereby teachers were not regularly involved in school-wide decision-making processes. When teacher leadership was enacted, it was in a form of authorised distributed leadership. The study further identified the autocratic leadership style of the principal and of the School Management Team members, as well as the non-inclusive school culture as main barriers towards the enactment of teacher leadership in the case study school. Despite these barriers, teachers’ high levels of enthusiasm were identified as an enabling factor that promoted the enactment of teacher leadership in the case study school.

At present nations do not only seek to improve economic performance but are also compelled to improve social development through improvements in socially and environmentally sustainable initiatives. Traditional measures such as Gross Domestic Product (GDP) which is derived from United Nations’ System of National Accounts (SNA) have been criticised given the inability to adequately account for these social and environmental aspects of social development. Given these perceived deficiencies in the conventional measures, several alternative objective measures have been proposed in an attempt to address these shortcomings. Therefore the primary aim of this study is to analyse, via a literature survey, these alternative objective measures of economic performance and social development. The alternative measures that constitute the survey are the Index of Sustainable Economic Welfare (ISEW), the Genuine Savings (GS), and the United Nations’ Human Development Index (HDI). Upon the completion of the literature survey, sustainable development theory is used to evaluate the extent to which the National Accounts and the alternative objective measures are consistent with Hicksian and Fisherian definitions of income and capital, which embody the concepts of sustainability and sustainable development. The evaluation reveals that the National Accounts neither conform to the Hicksian nor the Fisherian definitions of income, thus could not be viewed as a measure of sustainable income. It is found that the ISEW is consistent with the Fisherian definition of income and is also a partial indicator of sustainable development. The evaluation of the GS measure reveals that it is consistent with the Hicksian definition but not the Fisherian definition. In terms of overall sustainability, it is argued that GS is a partial measure of weak sustainability. The HDI is similar to the National Accounts, in that it is neither consistent with the Hicksian nor the Fisherian definitions of income and is also not a measure of sustainability. In summary, the study demonstrates that despite GDP's shortcomings as a measure of economic performance and social development, currently, there is no alternative approach which simultaneously addresses every flaw in GDP. However, all the alternatives yield a much better approximation of social development than GDP.

Re-imagining love and intimacy in the poetry of Gabeba Baderoon, Ingrid De Kok, and Makhosazana Xaba

- Description: This dissertation explores the ways in which the poetry of Gabeba Baderoon, Ingrid de Kok and Makhosazana Xaba challenge the sexist discourses that allow for the exploitation of women‘s bodies. It will also examine how they re-imagine the script 1 of heterosexual romantic love which places women in a submissive position and closes down possibilities for human connections which do not fit within the narrow strictures of this notion of love. The poems selected come from Baderoon‘s two collections, The Dream in the Next Body (2005) and A Hundred Silences (2006), an anthology of Ingrid de Kok‘s poetry spanning all her previous collections entitled Seasonal Fires: New and Selected Poems (2006), and Makhosazana‘s Xaba‘s first poetry collection, These Hands (2005). All three of these contemporary, South African, woman poets present critiques of the sexual exploitation of women and offer explorations of romantic love, relationships and sexual intimacy alternative to contemporary, patriarchal heteronormativity. This analysis will take cognizance of the influence of apartheid and colonial history on the formation of gender politics. It will also examine the representation of women as sexual objects and the spectacularized and graphic depictions of sex and how these poets can be seen to re-present women and re-script sex. Whilst Baderoon and De Kok are concerned with re-imagining heterosexual romantic love and sexual intimacy, their rethinking of love can also be read as useful in engaging with 'queer'2 sexuality and romantic love outside of the heterosexual norm along with Xaba, who is concerned with lesbian desire. Finally, all three poets experiment with traditional poetic form and techniques and it is through this experimentation with poetic language, and the employment of what Julia Kristeva calls the semiotic, that these poets are able to re-imagine love and intimacy. Thus they might be said, to use Kristeva‘s phrase, to stage a 'revolution in poetic language'.

Voting and meaning in Hooggenoeg, Grahamstown : an audience's reception of Grocott's Mail's 2011 municipal election coverage

- Description: This thesis examines the meanings that residents of the township of Hooggenoeg (in Grahamstown, in the Eastern Cape province of South Africa) made of the election coverage in the Grocott’s Mail newspaper during 2011 municipal elections in South Africa. In addition, this study also sought to understand the particular set of ‘normative roles’ played by the paper, both with reference to the well-established body of theory about the normative roles of journalism in a democracy, and in terms of the paper’s own conceptualisation of its role in the functioning of local democracy. Grocott’s Mail, the oldest independent newspaper in South Africa, provided extensive pre-election coverage, which included producing and distributing an unprecedented free edition of the paper. The paper also facilitated a town hall debate in order to encourage residents to vote, and empower them to make a more informed choice about their vote. Three qualitative research methods, namely qualitative content analysis, focus group interviews, and individual interviews were used to examine the relationship between the content provided by the paper and the audience’s process of ‘making sense’ and deriving meaning from the content provided. The study concludes that Grocott’s attempt to encourage democratic culture in Grahamstown, in keeping with the more ‘facilitative’ normative roles that the local media can play, was only partially successful. Much of the election reporting subordinated the voices of the ordinary people, and privileged reporting that focussed narrowly on the voting process, and which foregrounded the views of political parties. Overall this coverage largely failed to resonate with the Grocott’s readers who live in Hooggenoeg (a largely ‘coloured’ area of Grahamstown), whose key concerns in terms of their daily life – such as poverty, unemployment, crime, lack of services – seemed, to them, unaddressed by this election coverage and, consequently, was not as engaging or convincing as the publishers/editors had hoped it would be. It can be also argued that Grocott’s narrow conceptualisation of democracy as entailing only public participation in electoral processes failed to cater for how audiences can be made aware of how they can participate in governance beyond the election period.

- Description: The management of Nigeria high schools are noted for administrative practices in the management of their schools; hence the term administration is commonly used in their daily operations. This fact on ‘administration’ was emphasised by the Nigerian government in the National Policy on Education (Nigeria, 1981, p. 21). Therefor as a researcher from Nigeria, my rationale for embarking on this research study was to find out to what extent a public high school in Nigeria was still operating in a hierarchical, individualistic, authoritarian style of leadership or whether it has started embracing contemporary approaches such as distributed leadership. The main goal of this study was to explore leadership practices in the case study school with the main focus on how different people relate to each other in the various leadership practices of the school, such as staff and briefing meetings of the school. In addition, my research questions aimed at exploring the respondents’ perceptions of leadership and factors enabling or constraining the distribution of leadership in the school. The study is located within the interpretive paradigm. As a researcher in a wheelchair studying in South Africa I needed to find alternative ways of accessing the research site and gathering data. I was able to use electronic communication for the collection of my data. I used four different tools of data collection methods namely document analysis, observation, questionnaire and stimulated recall interviews. Findings from the study indicated that there was limited evidence of contemporary leadership approaches in the case study school. The school was still operating traditional leadership, while school activities were dominated by a hierarchical chain of command. What emerged from the leadership practices of the school could be termed authorised distributed leadership which was under the command of the school principal. Data also indicated that there were some forms of restricted teacher leadership in the management and administration of the school. In addition, findings revealed that the case study school was very good at the management and administrative functions. The school was very effective and efficient in the controlling and management of both human and material resources. Lastly, findings from the case study school indicated some enabling factors to the distribution of leadership in the case study school which include a culture of respect and cordial relations among the SMT and the teachers, Prominent among constraining factors to the distribution of leadership in the case study school were: cultural orientation of the people where the case school was located, exclusionary religious practices by the principal of the school and the inhibiting role played by the Ministry of Education. Finally, based on these findings, recommendations were made both for practice and for future research.

- Description: The textile industry in South Africa is a significant contributor to the chemical load that public wastewater treatment plants have to process, and the discharge of toxic substances, especially to the aquatic environment. In order to address this issue at factory level, the processes at a textile plant, JMV Textiles were chosen for investigation into the possibilities of minimization of discharges of harmful substances into the environment. The study followed the principles of cleaner production, and the processes that were investigated and revised were: The conventional peroxide bleaching process employed a peroxide stabilizer that did not biodegrade easily. The bleaching process was changed, so that the prevailing conditions in the fabric and dyebath facilitated bleaching without the addition of peroxide stabilizer, and also reduced the alkali and energy requirements. Polyester‐viscose fabric was pretreated by bleaching with hydrogen peroxide, which seemed to be unnecessarily rigorous, because polyester and viscose, unlike natural fibres, are relatively clean and have good whiteness in comparison with natural fibres. The proposed alternate pretreatment was a scour with detergent and alkali. The pretreatment for all polyester‐cotton fabrics was also a hydrogen peroxide bleach. Due to the ability of medium and dark shades to mask the natural tint of cotton fibres, a simpler alternate pretreatment, consisting of an alkaline scour with sequestering agent, was trialled. An unacceptable proportion of the dyeings on polyester was rejected for dye‐stains and dye‐marks. A possible solution exploited the properties of using the finishing auxiliary chemical to alleviate dye‐stains and dye‐marks during the dyeing stage, instead of using the chemical after dyeing. The highly toxic carrier that was used to facilitate level dyeing of polyester fibres that had unacceptable variation in their dyeing properties, was replaced by a less toxic carrier. The formulation for dyeing polyester was simplified to eliminate the auxiliary chemicals that were not essential to the dyeing process. Pale reactive dyed shades on cellulose and polyester‐cellulose were washed off only with hot water instead of detergent. The revised procedures consequential to the study, offered significant environmental benefits by reducing the concentration and volume of effluent produced, substituting a highly toxic carrier with a less toxic one and saving energy and water. Implementation of the suggested changes also offered financial benefits. The management of the factory, however, accepted and implemented some changes, but wanted further investigations for others and a phased approach to the other suggested changes.
