- Description: Temporary lentic wetlands are becoming increasingly recognised for their collective role in contributing to biodiversity at the landscape scale. In southern Africa, a region with a high density of such wetlands, information characterising the fauna of these systems is disparate and often obscurely published. Here we provide a collation and synthesis of published research on the aquatic invertebrate fauna inhabiting temporary lentic wetlands of the region. We expose the poor taxonomic knowledge of most groups, which makes it difficult to comment on patterns of richness and endemism.

- Description: Organisations today are experiencing immense pressure to act responsibly, both socially and ethically. Stakeholders expect organisations to operate with integrity, whilst still being profitable. This pressure is due to Corporate Social Responsibility (CSR) becoming increasingly a mark of good governance. Corporate performance is no longer measured by only financial statements, but CSR is deemed a corporate imperative for financial performance. This non-financial reporting has forced organisations to take cognisance of environmental, social and governance reporting, a process called Integrated Reporting. The purpose of this research was to explore website reporting of State Owned Enterprises (SOEs) in the transport sector. The study explored the phenomenon through six questions: What are the titles used to communicate CSR on SOE websites? What are the CSR activities communicated on SOE websites? What are the similarities and differences of the CSR initiatives communicated on the websites? Who are the stakeholders reached through CSR? What are the reporting practices on the SOE website? What are the similarities and differences of the reporting practices on the SOE websites. This research study was carried out in two stages. The first phase was to examine the corporate websites of the SOEs. The second phase was to use the data collected from the websites to understand CSR representation in SOEs. The purpose is to explore the communication of CSR on the various websites of the SOEs. A key finding of the research is that SOEs use different strategies to communicate CSR on their websites. SOEs communicate CSR activities using multiple titles and use various media on their websites. Additionally, there are variances with the framing of information on the websites. The varying communication strategies indicate the multiple stakeholders targeted by the different CSR focus areas. The research concluded that the different titles made it difficult for stakeholders to access information on the websites. Standardisation of CSR terms and consistency of reporting would make it easier for readers to access information. Further research is recommended in the adoption of strategic communication models by SOEs, as this will assist in the framing of websites.

- Description: The retention of nursing students in the undergraduate programme in universities is a global concern for the health care system, because of the low rate of nurse graduates. The strategies for retention for nursing students in undergraduate programmes in South African universities arguably have limited success in curbing failure to graduate. The failure to graduate rate of nursing students is a global phenomenon, where for example in 2009, the rate of failure to graduate in the United States of America was 30%. However, countries like Jamaica and Australia reported good retention rates through the use of various successful initiatives, such as student bursaries, student loans, scholarships and academic assistance. Previous studies in South Africa have showed that the incidence of nursing students’ failure to graduate rate is an ongoing challenge since the 1960s. Further, research has found that, despite the high annual enrolment of students into universities, only few nursing students graduate on time, while others fail to graduate. This phenomenon affects the rendering and quality of services to patients and clients in the health care facilities. When students fail to graduate from the programme, patients and clients get deprived of the services they would have got, had the students completed and graduated from the programme. On the other hand, the students themselves get frustrated due to the failure to complete the programme. Nursing Education Institutions (NEIs) also share in the disappointment and the loss of even one student who fails to graduate, because it is their obligation to graduate more nurses. Previous studies have sought to understand why students fail to complete their studies, and many factors have been identified. Therefore, there is need to further understand the factors associated with nursing student failure to complete their programme in different contexts such as South Africa. It is for this reason that the aim of this study was to develop a model for retention of nursing students in order to facilitate progression towards graduation in the undergraduate programme at the universities in the Eastern Cape Province of South Africa. The study endeavoured to answer the following research questions: What are the factors associated with retention-to-graduation of nursing students from the undergraduate nursing programme in the Eastern Cape Province, South Africa? What are the strategies to enhance retention to graduation of nursing students in universities in the Eastern Cape Province, South Africa? What conceptual framework can be developed for retention-to-graduation of nursing students from the undergraduate programme in the Eastern Cape Province, South Africa? What model could be developed for retention-to-graduation of nursing students from the undergraduate nursing programme in the Eastern Cape Province, South Africa? What guidelines should be formulated for the implementation of the model for retention-to-graduation of nursing students from the undergraduate nursing programme in the Eastern Cape Province, South Africa? To answer these questions, quantitative research approach with a descriptive, contextual and theory generation design was used. The study was conducted in four phases. Phase 1 used deductive concept identification to describe factors and strategies to enhance retention –to-graduation of nursing students in the undergraduate nursing programme. Phase 2 used inductive concept analysis for the development of a conceptual framework. In phase 3 reasoning strategies (inductive, deductive, derivation, synthesis and analysis) informed by data as well as the literature were used in order to generate a theory for model development. In phase 4, the guidelines for developing a preliminary model were formulated for theory implementation. The study setting was in the Eastern Cape universities, within faculties of Health Sciences. The researcher adapted Jeffreys’ Nursing Undergraduate Retention and Success (NURS) 2012 model as a data collecting instrument, which was pilot tested for reliability and validity. Permission to utilize the model was obtained. The targeted population was full time nursing students in the undergraduate nursing programme. A multistage stratified random sample from first year to fourth year level was used. The inclusion criterion was based on one being full time nursing student, aged between 18 and 50 years and from the Eastern Cape Province universities. Student nurses in colleges and part-time students were excluded from this study. The study adhered to research ethics and procedures by for example obtaining ethical clearance from the ethics committee of the University of Fort Hare and the other two selected universities. The ethical components were met: The Ethical clearance based on the following aspects: written consent to undertake the study; approval from the two of the selected universities; and permission to conduct a pilot study from the University of Fort Hare. Permission was also sought and obtained from Quality Assurance Unit in the Eastern Cape Province, in Bisho. The principle of beneficence; respect for human dignity; the right to self-determination based on the ethical principle of respect for persons; the principle of self-determination; the principle of justice, the right to fair treatment, the right to privacy, the right to informed consent were all considered. Data analysis was done through Statistical Analysis Systems (SAS) version 9.3 for quantitative data and Atlas Ti was used to analyse and quantify the open-ended section of the questionnaire. The results showed multidimensional factors associated with retention-to-graduation of the nursing students in the undergraduate programme. Strategies to enhance retention –to graduation were also indicated although there was no one perfect example since they were not evaluated for effectiveness. A retention-to-graduation model for nursing students in the undergraduate nursing programme was developed based on the results.

- Description: The purpose of this research study was to develop a support model for divorced professional nurses in the health-care facilities of the Department of Health, Eastern Cape, with guidelines to operationalise the model. Divorce is a process with psychological as well as social implications, and with a series of economic causes it also has implications in terms of the society and culture in which individuals operate. The main causes for divorce are adultery and domestic violence, especially against women and children (Lurea, 2011:99). A need for support from managers in the health-care facilities of the Department of Health, Eastern Cape during the process of divorce was identified by divorced professional nurses, since a lack of support and all the negativity that encompasses divorce could lead to severe depression, which will later have a negative effect on work performance (Abdul Kadir & Bifulco, 2010:858). The literature in this field of study, along with experience, indicates that it is imperative for divorced professional nurses to be supported in the workplace to help them to cope emotionally with their work demands, as prescribed by the South African Nursing Council. An explorative, descriptive and contextual qualitative design with theory generation was used to achieve the purpose of the study. Snowball sampling was employed to select participants, namely divorced professional nurses who were unknown to the researcher. A sample of 21 divorced professional nurses who work in health-care facilities in the Buffalo City Metropolitan Municipality in the Eastern Cape participated in the study. Data was collected by means of individual face-face interviews with divorced professional nurses. The interviews continued until data saturation was reached. Field notes supplemented data that could not be portrayed by audio-taped interviews, such as non- verbal communication in observed interactions. Data analysis was done using Tesch’s approach to open coding in qualitative research. Themes, categories and sub-categories emerged from the data analysis and were fully discussed, becoming fundamental units in the development of the conceptual framework as well as in the model. The researcher did a thorough literature review to conceptualise the identified concepts on which the model was based. The description and evaluation of the model, along with guidelines to operationalise the model, were done in accordance with the method described by Chinn and Kramer (2011:197). The justification of the research, the limitations, and the recommendations for operationalisation of the model of support for divorced professional nurses working in the Buffalo City Metropolitan Municipality of the Department of Health, Eastern Cape Province, and South Africa were indicated accordingly.

- Description: Psychobiographical researchers methodically formulate life histories and interpret them by means of psychological theories. The research typically focuses on exemplary and completed lives. The cases that are studied are usually of individuals who are of particular interest to society as a result of excelling in their particular fields, be they to benefit or detriment of society. Temple Grandin was chosen for this study using purposive sampling as she meets the psychobiographical requirement of being an extraordinary individual. As an individual with autism Grandin faced many challenges growing up. Despite a difficult and absent beginning, Grandin developed into a stable and scientifically creative adult who contributes to society. She excels as an animal scientist and designer of humane livestock handling facilities and has an international reputation for her contribution to the livestock industry and animal welfare. The primary aim of this study is to describe and interpret the life of Temple Grandin through Erikson’s (1950/1973) theory of psychosocial development. A mixed method approach (Yin, 2006) was employed for the conduction of this study. The overarching data processing and analysis guidelines for this study were provided by Miles and Huberman (1994, 2002a, 2002b). The conduction of the processing and analysis of data was aided by Alexander’s (1988, 1990) method of asking the data questions as well as an integration of Yin’s (2014) time series analysis with Erikson’s (1950/1973) triple bookkeeping approach. This study contributes to the development of psychobiographical research in South Africa as well as to personality and developmental theory.

- Description: This study examines how the implementation of CAPS Life Skills curriculum training (as a recontextualising process) is engaging teachers in environmental education. The research was centred on training manuals for Life Skills (Official Recontextualisation Field) and their use in CAPS training at district level in two Eastern Cape sites of recontextualisation (Professional Recontextualisation Field). During the training, teachers developed lesson plans that were reviewed and group interviews were conducted on the training process and its outcomes. The manuals, training process, lesson plans and interview transcripts were analysed for evidence of environmental education, notably content, teaching and learning methods and assessment strategies. Bernstein’s (1990) framework of the pedagogic device underpins this study. Here the concept of the relay is key for tracking the "relay” of the content, teaching and learning methods and assessment strategies through the processes of recontextualisation into the lesson plans for the field of production. During the process of de-location and relocation, gaps are created and this study sought to track and probe patterns of omissions that took place during the relay process in two cases of training. The review of the in-service training course process of recontextualisation and its cascading approach exposed challenges of omission as it became clear that at each level of the recontextualisation process, gaps were apparent. The study highlighted how the 3-5 day workshop process reviewed was not a robust model for professional development. It was not effective and changes in the mode of delivery and processes of support that reach into curriculum practice in the context of the school are recommended. The study concludes that there is a need for continuous professional development as teachers need ongoing support especially for a "new” curriculum like CAPS that is content driven.

- Description: This study examines how the implementation of CAPS Life Skills curriculum training (as a recontextualising process) is engaging teachers in environmental education. The research was centred on training manuals for Life Skills (Official Recontextualisation Field) and their use in CAPS training at district level in two Eastern Cape sites of recontextualisation (Professional Recontextualisation Field). During the training, teachers developed lesson plans that were reviewed and group interviews were conducted on the training process and its outcomes. The manuals, training process, lesson plans and interview transcripts were analysed for evidence of environmental education, notably content, teaching and learning methods and assessment strategies. Bernstein’s (1990) framework of the pedagogic device underpins this study. Here the concept of the relay is key for tracking the "relay” of the content, teaching and learning methods and assessment strategies through the processes of recontextualisation into the lesson plans for the field of production. During the process of de-location and relocation, gaps are created and this study sought to track and probe patterns of omissions that took place during the relay process in two cases of training. The review of the in-service training course process of recontextualisation and its cascading approach exposed challenges of omission as it became clear that at each level of the recontextualisation process, gaps were apparent. The study highlighted how the 3-5 day workshop process reviewed was not a robust model for professional development. It was not effective and changes in the mode of delivery and processes of support that reach into curriculum practice in the context of the school are recommended. The study concludes that there is a need for continuous professional development as teachers need ongoing support especially for a "new” curriculum like CAPS that is content driven.

- Description: Social media have become the preferred method of communication for individuals, organisations and even governments. These technologies have become ingrained in our everyday lives and have changed the way we communicate, collaborate are informed of recent happenings around the world. Social media websites are reported to be the most popular around the world. In the government sphere, social media is purported as a technology that will revolutionise citizen participation, service delivery and government-citizen interactions. Accordingly, governments around the world are steadily implementing social media in a bid to meet citizens’ demand for immediate and constant access to information, as well as increased opportunities to participate in government. Public participation has become an important focus area for government which could be used to effectively engage citizens and foster citizen trust. The United Nation’s E-government survey reports the presence of 125 countries on social media platforms. Despite the increased use of social media by governments, consensus among researchers is that governments need guidance on how to use social media effectively to achieve the potential benefits proposed by these technologies. Many social media adoptions by governments have been deemed as experimental; no formal action plan was designed, and many government employees are expected to learn social media use on-the-job. The aim of this research was to investigate and propose a social media model for public participation to leverage the opportunities provided by social media and present an effective and structured approach towards public participation. The research was designed as a mixed methods research using a case study based in the Eastern Cape Province of South Africa. The research involved a survey of citizens in the selected municipality based on the Uses and Gratifications Theory, interviews with employees responsible for social media in said municipality and a contents analysis of the existing social media pages of the municipality. The model was developed from the findings of the survey, interviews and existing literature. The implementation of the model was done in the Nelson Mandela Bay Municipality. The municipality appointed a social media champion responsible for obtaining support from top management and politicians within the municipality. Additional staff were added to the social media team and formal social media training was provided to the team. An official social media strategy was drafted and at the time of writing, needed to be approved by top management. The proposed model was operationalised within the Nelson Mandela Bay Municipality. This research makes several contributions to the E-government and social media fields in South Africa. The major contribution is the provision of guidance for South African municipalities to implement and use social media in an effective manner to achieve public participation. The research provided a phased approach to social media implementation that eliminates ad hoc experimentation and ensures the municipality’s social media activities are effective. The development of the model was based on the characteristics of the municipality and its citizens derived from the interviews and survey carried out. There are five phases in the model; Initialisation, Setup, Organisation, Institutionalisation and Maintenance. The model can be thought of as a guideline, and as such municipalities should adapt the implementation of the model to fit their organisational characteristics. The social media model will assist municipalities to determine the resources, tools and tactics to enable them to implement social media effectively, which will result in an improved engagement and participation process with citizens, and thereby foster trust.

- Description: Information technology (IT) trust is an important concept as people today rely more on IT to perform their tasks than before. Extensive research in Information Systems (IS) has explored trust and how it affects clients’ selection of different IT artefacts. Literature found trust to be a key determinant of technology use and an accelerator of understanding user perceptions regarding technology. Users’ perception of a technology’s characteristics influences their initial decision to adopt it; they are less likely to try the technology once they perceive significant risk linked to the technology exploration. The study focused on trust in relation to adoption of mobile applications (apps) for self-management of diabetic treatment regimens. The aim was to identify factors that should be incorporated in these apps to positively influence user perception of trustworthiness for enhanced adoption. According to extant literature, there are a myriad of apps which are available and ready for use, but diabetic patients are not maximising these opportunities to actively participate in managing their conditions. This is in spite of the numerous benefits accruable from using these apps to aid treatment regimens away from clinical settings or with minimal involvement of health personnel. This work is a qualitative study that investigated the reasons behind the low levels of trust in mobile applications for self-management of diabetes. The research design involved a survey and the study employed interviews for primary data collection. Twenty participants were engaged in the intervention. Some of these respondents were diabetic patients on treatment and others were health staff specialising in diabetes treatment. The participants were asked to download and try, for one month or more, the Diabetes:M app from Google play store for android devices or from iTunes for IOS devices. Thereafter, interviews were held with the participants to investigate their perceptions of the diabetes management app. Based on the outcome of the investigation, the researcher put forward a model proposing the attributes of trustworthiness of diabetes self-management mobile apps for enhanced adoption. Research findings showed that the apps for diabetes self-management should be usable, possess sufficient functionalities, give accurate information for decision-making, be reliable, and secure in order to enhance the trust of diabetic patients.

- Description: This thesis examines the role of cash and in-kind transfers in alleviating urban household food insecurity in Makokoba and Njube townships in Bulawayo, Zimbabwe. This assessment focuses on understanding the extent to which these transfers improve poor household access to food. The implications of cash and in-kind transfers on household dietary diversification are also examined. The thesis also scrutinises factors that deter the effectiveness of these transfers in addressing urban household food insecurity in the two townships. The study is guided by the Entitlement Approach (Sen, 1981) and Household Livelihood Security Framework (Frankenberger et al., 1995). The study combined qualitative and quantitative research methods in gathering and analysing data. Semi structured in-depth interviews, questionnaires, and key informant interviews were used to collect primary data. The thesis finds that cash and in-kind transfers have not significantly alleviated urban household food insecurity in Makokoba and Njube townships. As a result households receiving these transfers have not meaningfully improved their food consumption behaviours. Households continued to experience food insecurity characterised by skipping meals and eating small portions. Most households prioritised non-food expenditures and this has resulted in expending a small proportion of their cash transfers on purchasing inadequate food items. Both transfers have not meaningfully played a complementary role in enabling poor households to access a variety of food groups necessary for diversifying diets. The thesis also finds that a legion of factors deter the effectiveness of cash transfers in these townships. These include irregular distributions, low cash transfer value, incomplete food baskets, weak targeting mechanisms, less flexible implementation processes, automatic deletion of households from beneficiary database and duration of programmes. This thesis recommends redesigning of these cash and in-kind transfer programmes to effectively alleviate urban household food insecurity.

- Description: The implementation of Small, Medium and Micro Enterprise (SMME) strategy are not well understood and have rarely been addressed all nationally. The objectives of this study are, therefore, to establish a base level of understanding in order to assess the implementation of SMME strategy used by the Amathole District Municipality (ADM) Local Economic Development (LED) managers in disseminating information; analyse the structure for implementing SMME strategy used by the ADM LED managers; examine the challenges confronting the ADM LED managers in implementing SMME strategy; examine the skills needed by the ADM LED managers to adequately formulate and implement SMME strategy; and make recommendations to the municipality on how best the implementation of SMME strategy can support growth and development in the ADM. The study used a qualitative research design that involves a systematic review of documents. Data was collected through the review and analysis of available existing documents. Data analysis included using the documentary analysis derived from the journals, and books as well as reviewing the various data analysis done in relation to an assessment of the implementation of SMME strategy: A Case of Amathole District Municipality. Findings from previous literature revealed that there are constraints faced by the Amathole District Municipality (ADM) Local Economic Development (LED) Managers in implementing SMME strategy. The study confirmed some of the operational challenges were due to incompetency among the municipal managers, and lack of clear understanding of the implementation of SMME strategy used to support grow and development of SMME in the Amathole District. This study provides effective solutions to the identified challenges and impact as well as strategies to be adopted in order to alleviate poverty and provide job opportunities to the local communities. The implications of the findings are that unless the barriers named above are resolved, poverty and unemployment will continues escalating, communities will continue receiving and experiencing poor service delivery in the ADM and thus, would undoubtedly lead to poor economic growth and development. Management of the municipality must ensure that qualified ADM Managers are permanently employed and allowed to partake in the implementation of SMME strategy and community participation should be well encouraged as well as embarking on effective implementation of SMME strategy that would create an enabling and conducive environment for the small firm enterprises.

- Description: In a world of economic uncertainty and manifold social problems, South Africa has its own unique challenges of low economic growth, persistent budget deficits that produce increasing government debt and the highest level of economic inequality in the world. The history of injustice and economic marginalisation and the failure of the economy to provide inclusive growth drives an urgent need to address economic inequality through tax policy, placing ever more focus on wealth taxes as a possible solution. There is a hope is that taxing the wealthy may provide the opportunity to redistribute desperately-needed resources to those denied the opportunity to build wealth and who are trapped in the cycle of poverty. Yet, as appealing as a new wealth tax may seem, the introduction of such a tax carries with it a range of risks, not all of which are known. Of great concern is the possible effect on the economy, which, in its vulnerable state, cannot afford any loss of capital and investment. Very little research has been done on wealth tax in the South African context and there is a dearth of literature focusing on the views and perceptions of the wealthy individuals themselves. This qualitative study investigates the merits and disadvantages of a new wealth tax and seeks to identify any unintended consequences that could result from the implementation of a new wealth tax in South Africa, drawing from historical and international experience and primary data obtained from interviews with individuals likely to be affected by such a tax. Having explored the literature and international experiences with wealth tax and having probed the thinking of wealthy individuals who would be the payers of a wealth tax, the study finds that a new wealth tax may contribute towards the progressivity of the tax system, but it is doubtful whether such a tax would provide a sustainable revenue stream that would be sufficient to address economic inequality and there is a risk of causing harm to the economy. Recognising that the motivation for wealth taxes is often driven more by political argument and public perception than by rational quantitative analysis, the study also anticipates the introduction of a new wealth tax and suggests guidelines for the design of such a tax within the framework for evaluating a good tax system. This study informs the debate on wealth taxes in South Africa and contributes to the design of such a tax, should it be implemented.

- Description: The use of alien plant species as part of the livelihood resources of poor people raises conflicts with national legislation, which views these plants as threats to native plant biodiversity. However, there is also increasing body of literature on the contribution that some of these plants make to the livelihoods of poor people. The level of significance of some alien plant species to livelihoods is mostly highlighted in the case of female market participants who are in a position of household headship. Since most African cultures dictate the role of females as solely being that of homemaker while males are assigned the role household headship and breadwinner, women often find themselves having to shoulder the household responsibilities when the household head is no longer there. This was the case in the Nelson Mandela Bay informal prickly pear market that this study sought to investigate. Even though there were also male participants in the prickly pear market, the majority of participants in the market were female who also mentioned they were the sole breadwinner for their households. This study investigated the economic contribution that the prickly pear (Opuntia ficus-indica) informal market makes to the livelihoods of people living in the Nelson Mandela Bay. The significance of the market’s contribution to their livelihoods was examined through using the Sustainable Livelihoods Framework. The study revealed that although the prickly pear income was largely supplementary due to it being available for only three months of the year, the income was a safety net resource for the market participants who had limited access to other sources of income. The results also highlighted the reasons people were engaging in the informal prickly pear market. The main reason that was mentioned was unemployment. Through a livelihoods analysis using the Sustainable Livelihoods Framework, it was revealed that the other factors that were contributing to their unemployment were low levels of education, low levels of marketable skills, and old age. The study revealed through calculations of the estimated economic value of each market activity the potential of the prickly pear to be used as a poverty fighting tool. Although the results of this study only highlight the economic value of the prickly pear to people in a small area compared to the rest of the province and the country, the informal market’s significance still presents a strong case for the establishment of an agroprocessing industry, which would support the production of value-added products. Since the largest populations of the prickly pear in Uitenhage are currently under effective control by the cochineal species, promotion of its economic value instead of eradicating it without considering its value to the livelihoods of the people in the market could also ensure that its populations are kept under control. Job creation in the agroprocessing industry would not only improve the livelihoods of those involved in the market, but would also feed into the national economy instead of taking from it via the costs incurred during clearing.

Even though there were also male participants in the prickly pear market, the majority of participants in the market were female who also mentioned they were the sole breadwinner for their households. This study investigated the economic contribution that the prickly pear (Opuntia ficus-indica) informal market makes to the livelihoods of people living in the Nelson Mandela Bay. The significance of the market’s contribution to their livelihoods was examined through using the Sustainable Livelihoods Framework. The study revealed that although the prickly pear income was largely supplementary due to it being available for only three months of the year, the income was a safety net resource for the market participants who had limited access to other sources of income. The results also highlighted the reasons people were engaging in the informal prickly pear market. The main reason that was mentioned was unemployment. Through a livelihoods analysis using the Sustainable Livelihoods Framework, it was revealed that the other factors that were contributing to their unemployment were low levels of education, low levels of marketable skills, and old age. The study revealed through calculations of the estimated economic value of each market activity the potential of the prickly pear to be used as a poverty fighting tool. Although the results of this study only highlight the economic value of the prickly pear to people in a small area compared to the rest of the province and the country, the informal market’s significance still presents a strong case for the establishment of an agroprocessing industry, which would support the production of value-added products. Since the largest populations of the prickly pear in Uitenhage are currently under effective control by the cochineal species, promotion of its economic value instead of eradicating it without considering its value to the livelihoods of the people in the market could also ensure that its populations are kept under control. Job creation in the agroprocessing industry would not only improve the livelihoods of those involved in the market, but would also feed into the national economy instead of taking from it via the costs incurred during clearing.

- Description: A detailed study of the movement of sediment across the Cape Recife headland via the Noordhoek headland bypass dunefield was conducted. The Noordhoek HBD is important because of the environmental impacts anticipated on the sewerage works, settling ponds, and road to the Cape Recife lighthouse situated in the migration path of the dunefield to the ENE of its active boundary. The primary objective of the study was to investigate the movement of sediment in and through the Noordhoek HBD system. This study has provided sand transportation and dune migration rates by making use of various dune monitoring techniques. In doing so, useful predictions have been made as to when the settling ponds and the road to the lighthouse will be inundated. An indication has also been given as to how much sand moves through the system. Some key findings from this research included: the net migration direction of the Noordhoek HBD was found to be towards the east-north-east; the wind environment at the study area was classified as a high energy wind environment; this study has highlighted that various climatic factors such as rainfall and temperature influence the movement of sediment through dune systems; sediment transport was found to be directly related to the source area and topography; the central zone of the dunefield proved to be a groundwater recharge zone for the western and eastern zones; and the leading lobes of the migrating Noordhoek dunefield are gradually covering stabilising vegetation by pulses of dunes moving through. In this study, it was calculated that presently a total volume of about 26 000 m3 of sand is migrating into the vegetation at the leading lobes annually. If the Noordhoek HBD is left to run its natural course and migrate across the Cape Recife headland to the downwind beach, an approximate volume of 26 000 m3 of sand could be supplied to the downwind beach by this system. In doing so, it has the potential to play a role in replenishing some of the sand to Port Elizabeth’s eroded southern beaches via a natural process.

- Description: This research was an investigation of victims’ perspectives of ukuthwala practice in Mbizana Local Municipality. The aim of the study was to describe the consequences and experiences of ukuthwala practice relating to infringement of Human Rights, to identify the modus operandi men use to abduct (thwala) these victims, to investigate the reasons that hinder victims from reporting the practice to the police officials and to investigate programs that can be implemented to prevent the ukuthwala practice. This study focused on victims’ perspectives of ukuthwala practice, which seemed to be on the rise in Mbizana Local Municipality. The study used the feminist theory and the social exchange theory. The study is qualitative in nature and it employed the exploratory research design. The study collected data from married and divorced females aged between 16 and 45 years, who were residing in Mbizana Local Municipality at the time of the study and who were also victims of ukuthwala practice. The study used snowball non-probability sampling. In non-probability sampling, the chances of selecting a particular individual are not known. The study collected data using semi-structured in-depth interviews. Thematic analysis was used to analyze the data. The research findings show that there are a number of women and girls in Mbizana Local municipality who are in forced marriages. The study also found that the practice of ukuthwala (forced marriage) is still practiced in rural areas of Mbizana Local Municipality and victims face many challenges in these marriages. The findings reveal that girls as young as twelve years are forced to marry older men, in some cases with the consent of their parents or guardians. Most victims are unaware that the ukuthwala practice is illegal. Those who are aware are afraid to disappoint their families. The findings of the study also show that community members are keen help stop the ukuthwala practice. The study shows the important for the relevant government stakeholders to intervene. The study recommends that government departments and community members should work hand in hand in order to fight the issue of ukuthwala practice in the municipality.

- Description: The study was carried out to identify challenges that municipalities have with becoming Value Added Tax (‘VAT’) compliant. This study has been prompted by the ongoing findings reported by the Auditor General (‘AG’) in its audit reports. The increasing demand on the services of tax consultants also suggests that municipalities are having challenges in independently fulfilling their tax obligations. It was found that municipalities are often challenged with the application of the following VAT sections: The VAT apportionment methodology, section 8(27) dealing with unallocated payments, VAT reconciliations and claiming of VAT on invalid documentation and where VAT credits are denied. The main causes of non-compliance were identified as complexity of the tax laws, interpretation issues, behavioural attitude, lack of technical expertise within municipalities, and the fact that VAT is a self-assessed tax. Based on the findings of the study, it is recommended that all municipalities should be required to have a designated tax team to handle the tax matters of a municipality. The municipalities’ governing body, South African Local Government Association (‘SALGA’), should consider introducing penalties to non-VAT compliant municipalities. SARS should establish ‘customer relationships’ with the municipalities.

- Description: Although many developing countries use harvested rainwater (HRW) for drinking and other household purposes, its quality is seldom monitored. Continuous assessment of the microbial quality of HRW would ensure the safety of users of such water. The current study investigated the prevalence of pathogenic Escherichia coli strains and their antimicrobial resistance patterns in HRW tanks in the Eastern Cape, South Africa. Rainwater samples were collected weekly between June and September 2016 from 11 tanks in various areas of the province. Enumeration of E. coli was performed using the Colilert®18/Quanti-Tray® 2000 method. E. coli isolates were obtained and screened for their virulence potentials using polymerase chain reaction (PCR), and subsequently tested for antibiotic resistance using the disc-diffusion method against 11 antibiotics. The pathotype most detected was the neonatal meningitis E. coli (NMEC) (ibeA 28%) while pathotype enteroaggregative E. coli (EAEC) was not detected. The highest resistance of the E. coli isolates was observed against Cephalothin (76%). All tested pathotypes were susceptible to Gentamicin, and 52% demonstrated multiple-antibiotic resistance (MAR). The results of the current study are of public health concern since the use of untreated harvested rainwater for potable purposes may pose a risk of transmission of pathogenic and antimicrobial-resistant E. coli.

- Description: Vibrio infections remain a serious threat to public health. In the last decade, Vibrio disease outbreaks have created a painful awareness of the personal, economic, societal, and public health costs associated with the impact of inadequately treated wastewater effluents. This study was therefore designed to assess the occurrence of cholera and non-cholera causing Vibrio species in the final effluents of wastewater treatment plants and river waters in the Amatole (BT WWTP) and OR Tambo District municipalities (MT WWTP and QN River) of the Eastern Cape Province. Samples were collected monthly from December 2016 to November 2017 from the final effluent, 500 meters upstream and downstream of the discharge points and analysed for physicochemical parameters, Vibrio pathogens prevalence and their antibiogram characteristics using both culture-based and molecular techniques. Samples were collected aseptically using sterile 1L glass bottles containing 0.5 ml of sterile sodium thiosulphate solution and transported on ice to the laboratory for analyses within 6hrs of collection. The membrane filtration method was used for enumeration of presumptive Vibrio densities on thiosulfate citrate bile salt (TCBS) agar plates. Polymerase chain reaction (PCR) was then used to confirm the identities of the presumptive Vibrio species using the species-specific primers. The confirmed isolates were further subjected to molecular characterization to confirm their respective pathotypes. Antimicrobial susceptibility testing was done by the standard disc diffusion method recommended by the Clinical and Laboratory Standards Institute. The recovered Vibrio species were tested against a panel of 17 antibiotics. Physicochemical parameters measured include pH, temperature, electrical conductivity, salinity, turbidity, total dissolved solid (TDS), dissolved oxygen (DO), biochemical oxygen demand (BOD) and chlorine (only for BT WWTP). Unacceptably high levels of the assayed parameters were observed in many cases for TDS (66 - 879 mg/l), turbidity (2.0 -722.33 NTU) and DO (2.5 – 9.7 mg/l) as well as chlorine (0.2 – 3.2 mg/L). Presumptive Vibrio densities varied from 2.91 to 3.91 log10 CFU/100 ml and 2.67 to 3.18 log CFU/100ml, for BT WWTP and MT WWTP respectively. The densities for the QN River ranged between 2.51 to 3.99 log10 CFU/100mL. Out of 720 presumptive isolates recovered, 619 (86 percent) were found to be positive for the Vibrio genus. Molecular confirmation of the presumptive Vibrio species revealed the presence of V. fluvialis (16), V. vulnificus (12), V aliginolyticus (9), V. parahaemolyticus (37) and V. cholerae (5) isolates were confirmed. The susceptibility against 17 different antibiotics by the recovered species were examined. V. cholerae was notably resistant against nalidixic acid (3) and Ampicilin (2), all the V. vulnificus isolates were resistant against ampicillin (16), V. fluvialis showed resistance against ciprofloxacin and nalidixic acid, all (9) isolates for V. alginolyticus were resistant against ampicillin. V. parahaemolyticus showed resistance against cefutoxime (16), cefuxime (8) and ampicillin (13). The recovery of Vibrio in the discharged effluents throughout the sampling period even in adequately disinfected effluents is not acceptable considering that Vibrio are pathogenic bacteria. The findings of this study underline the need for constant monitoring of the physicochemical and microbiological qualities of discharged effluents and might also be suggestive for a review of the disinfection methods used at the treatment works as this might pose adverse health risk to the communities which still rely heavily on these surface waters.
