- Description: Image segmentation is one of the major problems in image processing, computer vision and machine learning fields. The main reason for image segmentation existence is to reduce the gap between computer vision and human vision by training computers with different data. Outdoor image segmentation and classification has become very important in the field of computer vision with its applications in woodland-surveillance, defence and security. The task of assigning an input image to one class from a fixed set of categories seem to be a major problem in image segmentation. The main question that has been addressed in this research is how outdoor image classification algorithms can be improved using Region-based Convolutional Neural Network (R-CNN) architecture. There has been no one segmentation method that works best on any given problem. To determine the best segmentation method for a certain dataset, various tests have to be done in order to achieve the best performance. However deep learning models have often achieved increasing success due to the availability of massive datasets and the expanding model depth and parameterisation. In this research Convolutional Neural Network architecture is used in trying to improve the implementation of outdoor scene image segmentation algorithms, empirical research method was used to answer questions about existing image segmentation algorithms and the techniques used to achieve the best performance. Outdoor scene images were trained on a pre-trained region-based convolutional neural network with Visual Geometric Group-16 (VGG-16) architecture. A pre-trained R-CNN model was retrained on five different sample data, the samples had different sizes. Sample size increased from sample one to five, to increase the size on the last two samples the data was duplicated. 21 test images were used to evaluate all the models. Researchers has shown that deep learning methods perform better in image segmentation because of the increase and availability of datasets. The duplication of images did not yield the best results; however, the model performed well on the first three samples.

- Description: The study sought to examine the skills needed by public officials for effective and efficient public procurement management. Supply Chain Management (SCM) is one of the key mechanisms enabling the government to implement policies and strategies, and to realise set objectives. However, there is a series of reported cases of incompetence by South African public sector practitioners when it comes to implementing duties they are designated to do, which have raised many concerns and led to the failure of SCM policies in the public sector. The Eastern Cape provincial government has been seen to be affected by poor procurement, and public procurement officials in the province face challenges such as redundant spending and misinterpretation of contracts and needs. These problems in the Eastern Cape provincial government have been especially highlighted in the Auditor General of South Africa’s reports. The study adopted a qualitative approach, and desktop research was used in a bid to ascertain the competence and skills required by public sector SCM practitioners in the Eastern Cape. Results showed that the logistics and supply chain sector have skills shortages, both in terms of soft and hard skills.Numerous studies have been done around the world to determine the types of skills that are required for successful supply chains. These results showed that there are skill categories that can be valuable in properly determining management effectively and efficiently in any institution. The study, therefore, recommended that the government provide funds for public sector employees to take professional education in the area of SCM. The government can also send its employees to education institutions that offer supply chain course.

- Description: Marion Island (46°54ʹS, 37°45ʹE) located in the Southern Ocean possesses one of the most oceanic climates on earth and sensitive to climate change. Climatologically, the sub-Antarctic is inadequately represented in the climate literature and this research therefore attempts to establish the recent changes that have occurred on Marion Island with regards to annual rainfall totals, monthly rainfall, rain days and non-rain days during the period from 1980 to 2018. This study found that annual rainfall has decreased by 24% from 2196.7 mm to 1678.57 mm from 1980 to 2018 and that the last decade (2010-2018) is the driest on record. The decrease in annual rainfall on Marion Island can be directly linked to the decreases recorded in monthly and daily rainfall. Rainfall in autumn has reduced by 35% over the last 40 years and the decrease in autumn rainfall is in part directly related to an increase in anticyclonic air circulation during which Marion Island is not influenced by any mid-latitudinal depressions. The frequency of rain days measured on Marion Island significantly decreased. Daily rainfall measuring less than 5 mm of rain a day contribute 50% of the total number of rain days. However, these high frequency low depth rainfall days contribute very little rainfall to annual totals. On Marion Island rain days that measure 10 mm and above contribute 65% of the total annual rainfall and it is also these type of high magnitude rain days that have significantly decreased since 1980. Multi-day consecutive rain events contribute the greatest proportion of rainfall to the annual rainfall totals (~40%). Linear statistics shows that the contribution to rainfall amount from these multi-day rainfall has halved since 1980. The frequency of non-rain days and consecutive non-rain days have significantly increased. The increased frequency of anticyclonic air circulation over Marion Island and the decrease of the traveling low-pressure systems affecting Marion Island are the probable cause of the increase in non-rain days. It is suggested that this increase in consecutive non-rain days has the most significant impact on the island’s biodiversity and landscape

- Description: South African Black visual artists have to contend with the racialized economic disparities of the country within which they are enmeshed. This make them susceptible to producing work with the sole motivation of not slipping (further) into poverty, which can greatly hinder our creative autonomy. We are further constrained by the fact that visual arts institutions, whose role it is to decide and regulate what constitutes legitimate art, still operate in accordance with whiteness and a white supremacist logic. The combination of these two factors can lead to the interpellation and artistic production of a Black subjectivity that predominantly caters to – and understands itself in relation to - whiteness. This process of subjectivation, which is performative, can - and regularly does - materialize in various ways through our studio practice. However, with the intervention of critical theory (and the application of strategies of resistance to hegemony that it can provide), interrogative self-reflexivity, and a singular perspective, it is possible to create work that disrupts and transgresses these norms, ultimately contesting the prevalent notion of Black identity as a homogenous experience.

- Description: The phenomenon of female sex workers in South Africa is yet to be understood from both the cultural and legal perspectives. This gap leads to various challenges experienced by female sex workers in the country. The purpose of this study was to explore the experiences of female sex workers in Buffalo City Metropolitan, Eastern Cape Province. A descriptive phenomenological design was used to gain in-depth understanding and knowledge on the experiences of female sex workers’ in reality and social context. The study targeted female sex workers aged between 18-49 years for interviews. Purposive sampling technique was used to recruit female sex workers and four focus groups of five members in each group were interviewed to collect data. Due to the sensitivity of the research topic, ethical approvals were sought and granted by University of Fort Hare Research Ethics Committee and the Eastern Cape Department of Health. Further, informed consent was obtained from study participants before data collection begun. Data analysis was done by using Tesch’ method steps. The findings indicated that in Buffalo City Metropolitan the female sex workers were experiencing human rights violation, stigma and discrimination, they were at risk of contracting HIV due to the nature of their work, and they were at risk of being in conflict with the law due to the nature of sex work in South Africa. The study recommends on the decriminalization of sex work in order to decrease rate of violence, rape and exploitation of female sex workers; the closure of all Illegal brothels as they promote drugs and substance abuse among this vulnerable group; and provision of counselling sessions for female sex workers by the Department of Social Welfare. The study concludes that peer educators training and embarking on campaigns in the community, media and social networks to promote ‘Anti-violence against sex workers’ is necessary. Therefore, the female sex workers need to be protected by police from any form of abuse and violence by the community, clients and pimps. This can address the psychological stress displayed by female sex workers in the studydomain

- Description: In nursing education, experiential learning is an important part of the curriculum and accounts for almost half of the requirements for the nursing programmes. A positive relationship with and collaboration between the training institutions and clinical placement facilities are vital for student achievement. Nurse educators are also expected to involve themselves in clinical accompaniment to bridge the theory-practice gap. Student nurses placed in midwifery clinical learning environments experience difficulty in meeting their experiential learning outcomes and programme requirements. Due to the overcrowded clinical facilities, they compete for the limited learning opportunities and resources which make the integration of theory and practice difficult. Therefore, this leads to delay in the commencement of community service by some of the nursing students as they do not graduate because of not achieving midwifery clinical outcomes and programme requirements. The purpose of the study is to assess factors affecting experiential learning for midwifery students at the public college of nursing in the Eastern Cape and the main objectives of the study were to: • Identify the challenges affecting the quality of learning in the clinical learning environment. • Determine the nature of supervision for experiential learning of midwifery students. • Determine the role of a nurse educator in the experiential learning of student nurses in midwifery clinical learning environment. Methods and analysis A quantitative, descriptive survey was conducted by making use of the Clinical Learning Environment, Supervision and Nurse Teacher (CLES+T) evaluation scale. The CLES+T is a reliable and valid evaluation scale for the gathering of information on the clinical learning environment and supervision of student nurses. The CLES+T evaluation scale was completed by 115 student nurses within the selected sites. The CLES+T evaluation scale is subdivided into three main sections with additional sub-sections: (1) the learning environment (2) the supervisory relationship and (3) the role of the nurse teacher (lecturer).

- Description: Aim: The purpose of this study was to determine the factors influencing folic acid/ferrous sulphate nutritional supplement intake among pregnant teenagers in Buffalo City Metropolitan Municipality (BCMM), Eastern Cape in South Africa.Methodology: This was a cross-sectional, descriptive study involving 300 purposively selected pregnant teenagers aged between 13 to 19 years, who were attending antennal clinic in BCMM. A self-designed questionnaire was used for data collection. Results: The majority (97.0 percent) of the respondents obtained their supplements from the clinic; took other medications (87.2 percent); the respondents regularly used nutritional supplements (71.7 percent); agreed that folic acid and ferrous sulphate were important for pregnancy outcomes (96 percent); should be taken before pregnancy and after birth (68.2 percent); and nurses had explained the possible pregnancy complications (71.7 percent). About 84.1 percent agreed that the medication containers were clearly labelled; and nurses had explained the side effects of folic acid/ ferrous folate (60.7 percent), and the likely action in case side effects occurred (56 percent). The majority of the participants also agreed that folic acid and ferrous sulphate are good for the unborn baby (88 percent); and are harmless to the unborn baby (75.3 percent). The majority (49.2 percent) of the participants did not consume dark leafy vegetables, cabbage (35.0 percent), liver (47.1 percent), beef/lamb (42.0 percent), fish (43.3 percent) and beans/legumes (36.4 percent). Participants indicated that folic acid and ferrous sulphate made them feel nauseous, inclined to vomit and also caused stomach pain.Conclusion: The majority of pregnant teenagers received their nutritional supplements from the health facilities over the counter. The study indicated that nausea, vomiting, forgetting to take the supplements due to busy schedules, non-availability of folic acid and ferrous sulphate in health facilities were the major reasons influencing the intake of folic acid and ferrous sulphate by pregnant teenagers. Also, there is low consumption of iron and folate rich foods by pregnant teenagers in this setting. Health practitioners including doctors, nurses and community health care workers needed to improve health education by including information on nutritional supplements and the importance an use of folic acid and ferrous sulphate during pregnancy.

- Description: The study sought to assess the effects of municipal demarcation board decisions on health care services. Since the democratic elections, the South African government was faced with the task of eliminating the racially based municipal system that segregated certain groups of people in service delivery. To deal with the determination and re-determination of municipal boundaries the Municipal Demarcation Board (MBD) was established in 1998. The study used secondary data to achieve its objectives. A number of official documents and sources that were used for this study. These included government documents, municipal documents, NGO documents, private sector documents. Results showed that municipal revenue is negatively affected by demarcations. Alfred Nzo District Municipality is no exception to this. Furthermore, demarcation processes have implications for health human resources and other municipal health processes. Human resources such as nurses and doctors are sometimes shifted from one municipality to another. Other negative consequences (especially in the transition period) may result from issues related to the supply chain, long-term contracts, municipal plans and policies, financial and other systems, information and databases, asset registers and asset maintenance, and repairs.

- Description: The study sought to assess the effects of municipal demarcation board decisions on health care services. Since the democratic elections, the South African government was faced with the task of eliminating the racially based municipal system that segregated certain groups of people in service delivery. To deal with the determination and re-determination of municipal boundaries the Municipal Demarcation Board (MBD) was established in 1998. The study used secondary data to achieve its objectives. A number of official documents and sources that were used for this study. These included government documents, municipal documents, NGO documents, private sector documents. Results showed that municipal revenue is negatively affected by demarcations. Alfred Nzo District Municipality is no exception to this. Furthermore, demarcation processes have implications for health human resources and other municipal health processes. Human resources such as nurses and doctors are sometimes shifted from one municipality to another. Other negative consequences (especially in the transition period) may result from issues related to the supply chain, long-term contracts, municipal plans and policies, financial and other systems, information and databases, asset registers and asset maintenance, and repairs.

- Description: Fission fragments, produced by neutron bombardment of natural uranium at the Physics Department, Jyväskylä, Finland, are studied in this work. The data had been sorted into 25 Y — y coincidence matrices which were then analysed. In this work we aimed to identify the fission products using Y-Y coincidence analysis and then study the beta-decay of some of the fission products. Sixteen fission products ranging from A = 94 to A = 136 were identified. Out of these fission products beta decay of the A = 100 (100/40 Zr – 100/41 Nb – 100/42 Mo) chain was studied in greater detail. We have also studied the variation of the relative intensities as a function of time of the 159-, 528-, 600-, 768-, 928- and 1502-keV Y-rav lines in 100/42 Mo and the profiles of the relative intensities have been modelled with the variation of the activity of 100/41 Nb against time. Configuration assignments of 100 Zr and 100/42 Mo are discussed.

- Description: This dissertation explores determinants and perceptions to participation in beekeeping by households’ as well as its contribution to household income. This is in a context that smallholder farmers’ participation is reported to be very low, despite several claimed benefits of beekeeping. Moreover, despite receiving substantial endorsements as a resilient climate-smart rural livelihood, off-farm, forest, non-timber diversification strategy; the uptake of beekeeping by smallholder farmers in the Eastern Cape Province of South Africa still remains very low. Against this background, this study used cross-sectional survey data to gauge smallholder farmers’ perceptions and factors that influence their participation in beekeeping using a binary regression model; further, it measured the contribution of beekeeping to rural household income using a linear regression model. Descriptive statistics revealed that majority of the people from the study area have positive perceptions regarding beekeeping. Regression estimates further indicate that beekeeping is mostly conditioned by shared perceptions, institutional and socio-economic factors that are worth targeting to promote the uptake of beekeeping as a livelihood. Public policies that influence the institutional framework (extension, credit and market) in favour of beekeeping are more likely to promote participation in beekeeping activities. Also, more research on the documentation and benefits of beekeeping supported by investments targeting educational campaigns towards promoting positive attitudes and dispelling fears and myths surrounding beekeeping as an enterprise, will also promote the participation of smallholder farmers in beekeeping. Regression estimates for determinants of household income revealed a significant positive contribution of beekeeping to household income, education, gender and age. Promotion of beekeeping may therefore address household income that is worth targeting to address rural poverty. The study therefore concludes that to fully unlock the income potential of beekeeping for smallholder farmers, development agencies need to address several negative perceptions and institutional factors that affect beekeeping participation, while more research is required to quantify the claimed benefits of beekeeping, given their positive potential to promote farmers’ interests in beekeeping.

- Description: Lepidopteran stem borers are infamous among cereal crops and sugarcane growers because of their pests status in these crops. Lepidopteran stem borers often infest cereal crops such as maize (Zea mays L.), sorghum (Sorghum bicolor L.), pearl millet (Pennisetum glaucum L.), sugarcane (Saccharum spp.). However, in natural habitats, the stem borers feed on a wide variety of wild host plants species in the Poaceae, Cyperaceae and Typhaceae families. Some wild host plants in close approximation of cultivated fields act as reservoirs for stem borers during the absence of cultivated crops. Understanding of the diversity of the stem borers, their host plants and their interactions was very important in development of management strategies for the stem borer populations. For an example, grasses such as Napier grass (Pennisetum purpureum Schumach.) and Sudan grass(Sorghum vulgare var. Sudanense (Piper) Hitchc.) act as trap plants whereas other grasses such as Molasses grass (Melinis minutiflora P. Beauv.) and legume silverleaf (Desmodium uncinatum (Jacq.) DC.) act as repellents to stem borer moths. In South Africa, studies on the diversity and distribution of lepidopteran stem borers in wild habitats are limited. Previous studies concentrated on diversity, abundance, and distribution of stem borers and their natural enemies on cultivated crops because of the economic importance of cultivated crops. In view of the foregoing, this study was conducted to investigate the diversity and distribution of lepidopteran stem borers and their host plants in wild habitats in the Western Cape and KwaZulu-Natal Provinces of South Africa and to generate mtDNA COI sequences of the stem borer species in natural habitats. These sequences can be accessed in databases and assist in identification of previously unknown stem borers in cultivated crops. Therefore this study contributes to development of monitoring and early identification tool of the stem borer movements between host plants assemblages. Surveys were conducted in Western Cape and KwaZulu-Natal provinces, South Africa during the rainy season of 2014 and 2015 in 38 localities to catalogue the diversity of lepidopteran stem borers in wild host plants. The sites visited belonged to five vegetation types: grassland, the Indian Ocean coastal belt, savanna, forest, and wetlands. A total of 237 lepidopteran stem borers was collected during study yielding 21 species that belonged to Noctuidae (Acrapex sp. 89, Acrapex sp. 90, Acrapex sp. 92, Acrapex sp., Acrapex minima, New genus NG11), Sesamia calamistis Hampson, Sesamia sp., Sesamia natalensis Le rü sp. nov., Sesamia nov sp. 4, Sesamia nov sp.36, Conicofrontia bipartita Hampson, Conicofrontia sesamoides Hampson, Conicofrontia diamensa Hampson, Pirateolea piscator Fletcher , Sciomesa mesophaea Aurivillius), Crambidae(Chilo partellus Swinhoe and Calamotropha paludella Hibner) Pyralidae (Phycitiinae sp. 1 and Phycitiinae sp. 2) and Tortricidae were recorded from 20 wild host plant species. Stem borer wild host plants species were Cymbopogon dieterlenii Stapf ex Schweick.,Cymbopogon nardus (L.) Rendle, Cymbopogon pospischilii (K. Schum.) C.E. Hubb., Digitaria macroglossa Henrad, Eriochloa meyeriana (Nees) Pilg.,Eriochloa fatmensis (Hochst. &Steud.) Clayton, Imperata cylindrica (L.) Raeusch., Miscanthus capensis (Nees) Andersson, Paspalum urvillei Steud., Panicum maximumJacq., Pennisetum purpureum Schumach., Phragmites australis (Cav.) Trin. Ex Steud.,Rottboellia cochinchinensis (Lour.) Clayton, Setaria homonyma (Steud.) Chiov.,Sorghum arundinaceum (Desv.) Stapf.,Cyperus divesDelile, Cyperu sdistans Pursh, Cyperus fastigiatus Rottb., Cyperus sexangularis Nees and Typha latifolia (L.).The diversity of stem borer species varied among vegetation types, host plants, and altitude. Morphological identification of specimens from these surveys indicated a high diversity of stem borer species in the Noctuidae family, followed by Pyralidae, Crambidae, and Tortricidae respectively. Of all the stem borers collected in the two provinces, noctuid species were most abundant in all vegetation types from low to high altitudes representing 62.45percent, whereas pyralids, crambids, and tortricids made up 26.58percent, 9.28percent, and 1.69percent respectively. The diversity and distribution of stem borers were affected by latitude. KwaZulu-Natal had higher latitudes ranging between -28.37717˚ and -31.07800˚ and had higher diversity, distribution and the of stem borers host plants, while Western Cape Province had lower diversity and distribution at latitudes ranging between -34.00280˚ and -34.05343˚. Morphological identification of stem borers was complemented with the mtDNA cytochrome oxidase I gene (COI) to investigate evolutionary relationships between the stem borer species collected in this study. Of the 12 sequences searched from the databases and the Genebank only five sequences were identified to species level; UFH024 was identified as Sciomesa mesophaea, the other four were identified as Conicofrontia sesamoides, Conicofrontia bipartita; and the first ever record of Calamotropha paludella in South Africa and Pirateolea piscator. Five sequences; UFH026, UFH028, UFH029, UFH030, UFH032 were only identified to order.

- Description: The discussion on the extent to which audit committees perform the oversight function of financial governance is important. This is particularly so in the Eastern Cape where the implementation of the Public Finance Management Act (PFMA) of 1999 has not significantly improved financial management. The deteriorating financial management environment of provincial departments impacts negatively on service delivery and is therefore a matter of great concern to the political administrators at both national and provincial levels. The objective of this study is to determine how effective audit committees are in Eastern Cape provincial departments and how this translates into good financial governance and, ultimately, improved service delivery. To achieve this objective, a literature review of the link between audit committee effectiveness, accountability and corporate governance in the public sector was conducted. It was found that audit committees in the public sector have similar responsibilities to that of the private sector and lack of accountability in the public sector impacts negatively on service delivery. A second literature review was conducted to highlight the current state of public financial management in South Africa and how this has had an impact on financial management in Eastern Cape provincial departments. A qualitative research methodology was applied because the researcher is of the opinion that the research question asked is more interpretive than predictive. An interview survey was conducted in which senior management officials were selected from provincial departments and interviewed using semi-structured questions. The research study concluded, that provincial departments in the Eastern Cape have all established audit committees in line with the Public Finance Management Act (PFMA) National Treasury regulations. These committees are however ineffective. Ineffectiveness is as a result of, among other factors, lack of stability in accounting officer and chief financial officer positions. Secondly, senior management have not been made to account for the persistent negative audit outcomes in their departments. The research recommends that the political leadership of the province should ensure stability in leadership, particularly in the position of accounting officer and the chief financial officer.

- Description: From Integrative Summary: This research paper comprises of three sections that include: an evaluation report, a literature review and the research methodology. The first section assesses the management of resistance to change as encountered during the ELIDZ structural re-alignment initiative. The assessment was done after the change initiative had been implemented to see what could be learnt from the exercise, in order to be better prepared for future change programmes. The implemented change was initiated by the CEO of the ELIDZ but its criticality in terms of purpose, or the need for the change was unclear to many employees at the time of initiation. An examination of the literature on change management highlighted the importance of managing resistance to change as part of a change initiative, so as to ensure a successful transition. The review of the literature on management of resistance to change in section 2 of this paper examines the definition of management of resistance to change and in particular, covers key factors like change readiness, participation in change and change communication. These key concepts underpin effective management of resistance during change. The literature on management of resistance to change with respect to the role of change readiness, participation in change and change communication was used to develop a questionnaire that was used to assess the ELIDZ change initiative. The questionnaire was developed in a Likert Scale format with questions across the spectrum of change readiness, change participation and change communication. Section 3 of this paper describes how the quantitative research was provided to the population sample of employees from the ELIDZ where the questions on change readiness, change participation and change communication was used to assess the effectiveness of management of resistance to change during the ELIDZ change initiative. In addition section 3 provides an explanation of how the results of the research were derived. The results on change readiness suggest that the ELIDZ change initiative did not address change readiness adequately. There is therefore a risk of resistance to change that could manifest. This also indicates that change readiness must be planned more thoroughly in future change endeavours. Most of the population sampled did not feel that they participated in the change initiative, suggesting that the ELIDZ did not address participation in the change initiative adequately. Not enabling employees to actively participate in the change is tantamount to decreasing the potential for acceptance of change and increasing the risk of resistance to change. In order to ensure that future change initiatives are not met with employee resistance to change, the ELIDZ should plan for employee participation throughout the change process. The extent to which change communication was addressed in the ELIDZ change initiative was demonstrated by very poor results. The results from the population sampled suggest that the change was not well communicated to employees. As change communication is known to reduce the potential for resistance to change, it is imperative for the ELIDZ to plan for comprehensive communication strategies to cover the change process for future change action.

In order to ensure that future change initiatives are not met with employee resistance to change, the ELIDZ should plan for employee participation throughout the change process. The extent to which change communication was addressed in the ELIDZ change initiative was demonstrated by very poor results. The results from the population sampled suggest that the change was not well communicated to employees. As change communication is known to reduce the potential for resistance to change, it is imperative for the ELIDZ to plan for comprehensive communication strategies to cover the change process for future change action.

- Description: The focus of this study was on the experiences of a small sample of local women who are HIVpositive and are living in poverty. The researcher was interested in exploring the psychological and social experiences of these women using Interpretive Phenomenological Analysis. This research aimed at giving these women a voice to express their first-hand, personal accounts of living with HIV in poverty. Data was analysed for meaningful units, which were interpreted inductively and hermeneutically, and categorised into super-ordinate themes. Six themes within the participants' experiences of living with HIV were determined, namely: (I) experiences of diagnosis, (2) disclosure experiences, (3) stigma, (4) ARV experiences, (5) experiences of social support and (6) poverty. This research found that after an HIV-positive diagnosis, most women experience a variety of emotional reactions. These reactions however seem to change overtime into positive acceptance of the HIV diagnosis. Most of the women in this study preferred to use partial disclosure than to fully disclose their HJV-positive status openly to families, friends and to their community. Reasons for not using full disclosure included fear of discrimination and stigma, which included a fear of being rejected or being blamed for their status and a fear of losing relationships. It was also evident from the findings that most of the women had experienced stigma directly and therefore partial disclosure was used as a coping mechanism to protect the self from further harm. It was also revealed that stigma not only has a negative impact on disclosure but also on social support and ARV experiences. Because ofHIV-related stigma, lack of social support was a struggle that almost all the women in this study had experienced. Lack of understandings about their medication also had a negative impact of the ARV experiences. Stigmas along with poverty are the major struggles that HIV -positive women have to deal with in their day to day living. The findings of this study reveal a need for further research in this experiential area as well as campaigns and education around issues such as stigma, medication, and emotional difficulties associated with HIV.

- Description: This Research was undertaken to explore the challenges faced by the Eastern Cape Department of Local Government and Traditional Affairs Integrated Development Planning Unit to support municipalities to deliver credible Integrated Development Plans (IDPs), using Sunday’s River Valley Municipality as a case study. The legal obligation of the Department of Local Government is to support Municipalities to able them to perform their function and execute the duties allocated to them. This mandate originates from the Constitution of the Republic of South Africa, Act 108 of 1996. The Provincial Department of Local Government Integrated Development Unit is therefore obliged to support and guide municipalities in the development of IDPs by mobilizing and coordinating sector departments to participate in IDP processes, and to identify and allocate funds for projects. It is suggested that the DLGTA IDP Unit is not doing enough to support municipalities so as to deliver credible IDPs, hence the wide-spread violent service delivery protests. The study aimed at establishing whether there is a direct link between the efforts or not of DLGTA to help the municipality to develop a credible IDP and service delivery protests. The IDP may be credible, but the implementation may be flawed, or funding does not flow as expected, or the people on the ground may not understand that it may take years to deliver services. The study targeted senior managers of coordinating Departments, the Sunday’s River Valley Municipality (SRVM) and IDP Managers of SRVM and the Cacadu District Municipality (CDM). The study discovered that sector departments do not participate meaningfully in IDP processes mainly because: (1) SRVM does not extend invitations to all sector departments to attend IDP meetings; (2) There is no legal obligation to participate at local level; (3) There appears to be no commitment shown by senior managers of SRVM on IDP Processes. The DLGTA IDP Unit efforts to assist SRVM to deliver credible IDPs cannot be deemed successful, because the SRVM IDP continued to receive medium rating score for four years in succession. The DLGTA IDP Unit never paid attention to the issues cited above as the cause of stagnation of SRVM IDP. The DLGTA IDP Unit was not aware that the issues cited above were the cause for the poor SRVM IDP until the researcher brought it to their attention. It is therefore recommended that the culture of participation in the IDP processes by top management of both SRVM and DLGTA should be included in the performance contracts of top management officials. It is also recommended that the Inter Governmental Relations (IGR) Framework Act be reviewed to recognize IGR IDP Structures at local level such as IDP Representative Forums. The Act currently is silent on those structures at local level.

- Description: This study explores issues of sustainability, viability and stability in the projects funded by the Department of Social Development, situated in the Nelson Mandela Bay. The researcher makes use of a combination of qualitative and quantitative research designs to gather data. The sample consisted of about three members from each of the four projects selected, as well as two officials of the Department of Social Development in the Nelson Mandela Bay. The respondents participated in structured and semi-structured interviews exploring their demographic information, information about the project and how it is managed, views and opinions about differences between a business venture and a project, their understanding of what constitutes a sustainable, viable and stable income-generating project as well as their opinions about what would contribute to ensuring sustainability, viability and stability in these projects. The results of the study reveal that it is important to structure and run the income generating projects using business principles which include vigorous marketing and proper costing. There is also a need to train the participants in business management so that they can run the ventures successfully. It has also become apparent that a clear leader or manager is lacking and thus decision making process is too long, meaning a meeting must take place involving all project members before a decision that affects the operations can be made. Almost all key factors contributing to a sustainable and viable income generating project, as defined by Mango (2004) and Madi (2007) were also found to be lacking in these projects.

- Description: The city of Port Elizabeth was established as a British colonial town in 1820 when the settlers arrived. With them, they brought ‘civilization’ from Europe, which can be seen in parts of the historic urban structure of Port Elizabeth as well the art that remains. The largest public space of the old city was St. Georges Park. The current museum buildings are part of the collection of British heritage buildings in a surrounding the park. The park is hierarchically located to align with other important places in the urban fabric. Today the park is used by city members as a sporting facility only. Club members of the various sporting facilities such as bowls, tennis, swimming and cricket clubs enjoy these amenities mostly on a Saturday. The park is also home to the famous Duckpond Cricket Pavilion designed by award winning architect John Rushmere. It is the second oldest cricket club in South Africa and has hosted various first events. The museum however has run out of space a few years ago and proposals have been formed by city officials to connect the existing gallery buildings, which would result in the closure of the gateway into the park while also disrupting the general urban flow and rhythm of the city. Finally, any new museum in South African should try to serve our diverse cultures and preserve a heritage whether pleasant or unpleasant. This type building needs to be a new type of place and be an appropriate symbol of our attitudes towards colonial heritage.

The ecology and conservation of Mackinder's eagle owls (Bubo capensis mackinderi) in central Kenya in relation to agricultural land-use and cultural attitudes

- Description: The loss of habitat to agriculture is a worldwide problem for biodiversity conservation. One species that has seemingly been able to adapt to the conversion of forests to farmlands is Mackinder’s eagle owl (Bubo capensis mackinderi), which inhabits highland areas, but little is known of its ecology, especially outside of protected areas. This study examined the impact of agricultural practices and farmer’s attitudes on the foraging and population ecology of the Mackinder’s eagle owl in central Kenya. Owl territories were monitored monthly from June 2004- October 2006 for signs of occupancy, breeding activity, mortality and to collect data on food resources. Nest site characteristics were measured for all known nests. Because previous studies showed an affinity for rodents, small mammals were trapped monthly using mark-recapture methodology. In each territory, the type and amount of farm crops were measured each month and farmers were interviewed about their knowledge and beliefs about owls. Mackinder’s eagle owls in central Kenya lived at extremely high density 0.87 owl pairs/km². This density was high compared to other populations of Mackinder’s eagle owl and to Eurasian eagle owl (Bubo bubo) populations in Europe. Breeding success was 48% over three years and this compared well with other species of eagle owl inhabiting human-disturbed areas. All nests and roosts were located in river valleys, and all successful nest sites were located on cliffs or other inaccessible rocky terrain. Nest sites were located adjacent to farms, which provided for both open hunting and an abundance of prey. Breeding activity was concentrated after the rainy seasons and this was likely linked to prey availability after the rains. Agricultural activities generally had a positive effect on rodent populations. Small mammal trapping results revealed that rodents were over 14 times more abundant in farms than in adjacent grassland habitat. This population of Mackinder’s eagle owl had a very catholic diet and consumed mostly mammalian prey species including hares, giant rats, root rats, grooved-tooth rats and small rodents. Small rodents accounted for almost half of the owls’ diet and when their numbers increased, owls responded by consuming more of them, indicating the importance of farming activities to this population of owls. Other populations of eagle owl inhabiting human-disturbed areas had diet widths positively related to levels of habitat disturbance. This result supported optimal foraging theory that more productive environments have predators with more specialized diets, while patchy environments have generalist predators. The ecology of this population of Mackinder’s eagle owls was heavily influenced by human agricultural activities, which generally had a positive effect on their population. Farming activities changed rapidly both within and between seasons as plots were small and neighbouring farmers planted various crops at different times of the year and this was enhanced by irrigation in some areas. Year-round availability of forage within farms had a positive effect on owl prey species, some of which increased relative to the type and amount of crops found in farms. However, 57% of owl injuries and mortalities that occurred were related either directly or indirectly to human activities. Cultural prejudices against owls remain the biggest threat to this population’s long-term persistence. Farmer education was shown to play a significant role in overcoming negative beliefs about owls. Because Mackinder’s eagle owls are highly adaptable to anthropomorphic landscape changes, largely due to their adaptability as food generalists, they are one of the few top predators remaining in this highly disturbed agricultural system. However, populations within agricultural areas remain especially vulnerable to negative human attitudes towards owls due to their close association with human activities.
