  • Description: High failure rates in English as a second language at secondary school level have become a concern in the Namibian education sector. From 2005 until 2013, the overall performance of the grade 12 learners in English as a second language on Ordinary level in the Oshana region was unsatisfactory. In fact, only a minority (18.52 percent) of the grade 12 learners obtained a grading in the range of A to D in comparison to the majority (81.48 percent) of learners who obtained a grading of E to U. The poor performance was attributed to: poor sentence structure, syllabification and spelling (Directorate of National Examination and Assessment, 2007-2010). The causes of these low performance rates however, were not scientifically explored in this region. Therefore this study embarked on an investigation in order to identify the reasons behind the low performance rates of the grade 12 Oshiwambo speaking learners of English and to determine whether the impressionistic results from the Directorate’s report correlate with the present study’s findings. In order to understand the dynamic linguistic system of the learners, a contrastive analysis of Oshiwambo and English was done in order to investigate the potential origins of some of the errors. An error analysis approach was also used to identify, classify and interpret the non-standard forms produced by the learners in their written work. Based on the results obtained from this study, a more comprehensible assessment rubric was devised to help identify learners’ written errors. A group of 100 learners from five different schools in the Oshana region was asked to write an essay of 150 to 200 words in English. The essays were analysed using Corder’s (1967) conceptual framework which outlines the steps that a researcher uses when undertaking an error analysis study. The errors were categorised according to Keshavarz’s (2006) linguistic error taxonomy. Based on this taxonomy, the results revealed that learners largely made errors in the following categories: phonology/orthography, morpho-syntax, lexico-semantics, discourse and techniquepunctuation. The study concluded that these errors were most likely due to: first language interference, overgeneralisation, ignorance of rule restriction and carelessness. Other proposed probable causes were context of learning and lack of knowledge of English grammar. The study makes a significant contribution, in that the findings can be used as a guide for the Namibian Ministry of Education in improving the status quo at schools and informing the line Ministry on various methods of dealing with language difficulties faced by learners. The findings can also empower teachers to help learners with difficulties in English language learning, thereby enabling learners to improve their English language proficiency. The study has proposed methods of intervention in order to facilitate the teaching of English as a second language in the Oshana region. In addition, the study has devised an easily applied assessment rubric that will assist in identifying non-standard forms of language used by learners. The reason for designing a new rubric is because the rubric which is currently being used is believed to be subjective, inconsistent and lacks transparency. , Name in Graduation Programme as: Nghikembua, Anneli Ndapanda

  • Description: The therapeutic potential of stem cells is already being harnessed in clinical trails. Of even greater therapeutic potential has been the discovery of mechanisms to reprogram differentiated cells into a pluripotent stem cell-like state known as induced pluripotent stem cells (iPSCs). Stem cell nature is governed and maintained by a hierarchy of transcription factors, the apex of which is OCT4. Although much research has elucidated the transcriptional regulation of OCT4, OCT4 regulated gene expression profiles and OCT4 transcriptional activation mechanisms in both stem cell biology and cellular reprogramming to iPSCs, the fundamental biochemistry surrounding the OCT4 transcription factor remains largely unknown. In order to analyze the biochemical relationship between HSP90 and human OCT4 we developed an exogenous active human OCT4 expression model with human OCT4 under transcriptional control of a constitutive promoter. We identified the direct interaction between HSP90 and human OCT4 despite the fact that the proteins predominantly display differential subcellular localizations. We show that HSP90 inhibition resulted in degradation of human OCT4 via the ubiquitin proteasome degradation pathway. As human OCT4 and HSP90 did not interact in the nucleus, we suggest that HSP90 functions in the cytoplasmic stabilization of human OCT4. Our analysis suggests HSP90 inhibition inhibits the transcriptional activity of human OCT4 dimers without affecting monomeric OCT4 activity. Additionally our data suggests that the HSP90 and human OCT4 complex is modulated by phosphorylation events either promoting or abrogating the interaction between HSP90 and human OCT4. Our data suggest that human OCT4 displays the characteristics describing HSP90 client proteins, therefore we identify human OCT4 as a putative HSP90 client protein. The regulation of the transcription factor OCT4 by HSP90 provides fundamental insights into the complex biochemistry of stem cell biology. This may also be suggestive that HSP90 not only regulates stem cell biology by maintaining routine cellular homeostasis but additionally through the direct regulation of pluripotency factors. , Thesis (PhD) -- Faculty of Science, Biochemistry and Microbiology, 2015

  • Description: This study is a comparative analysis of the way that academics and journalists evaluate media coverage of news about the environment. The purpose is to gain insight into the kind of contributions that each of these groups can make to debates about the role that such coverage should play within processes of public deliberations about the environment. The dissertation begins by establishing theoretical terms of reference for assessing discussions of the journalistic coverage of the environment. It proposes that it is of value to consider the conceptualisation, within such discussions, of credible knowledge about the environment and, more particularly, to establish whether such conceptualisation is based within a positivist, interpretive, or critical realist paradigm. It is demonstrated that each of these epistemological traditions brings valuable perspectives to the discussion of journalism about the environment within such literature. It is, however, the positivist perspective that remains dominant, and this limits the extent to which the potential of the other two epistemological positions are fully realized. It is also demonstrated that there is a tendency, within this literature, to focus on the performance of individual journalists with minimal attention to the particularities of institutional and social context. It is proposed that this tendency results from the adherence to a positivist approach to the evaluation of journalism. The dissertation then describes the design and implementation of the empirical component of the study - dealing with decisions made about the overall methodological framing, the choice of method, the fieldwork plan and the approach to analysis. It is explained that the aim of the empirical component was to examine South African print journalists’ discussions of coverage of the environment in their own publications, and to compare such discussion to that which is represented in the academic literature. The dissertation then presents a summary of the themes that emerged from the analysis of the interview material that formed part of this empirical work. It is demonstrated that the evaluation of coverage of the environment, as articulated by the research participants, is informed by many of the assumptions and values that can be identified within academic literature. Such evaluation is, furthermore, similarly informed by a positivist, interpretive and critical treatment of knowledge - with, again, a tendency for the positivist position to dominate. One important difference is that the research participants include more references to institutional context. It is proposed, however, that the tendency to prioritise a positivist epistemological framing continues to place limitations on the extent to which the participants are able to fully articulate their knowledge about such context.

  • Description: Small and Medium Size Enterprises (SMEs) are considered a vital catalyst for economic growth and a source of job creation. In South Africa, with the high levels of unemployment, the contribution made by SMEs is of particular importance. However this sector of the economy is plagued by a high rate of business failure. In an effort to improve the current situation, this study sought to identify which business practices and entrepreneurial traits are present in SMEs in the Eastern Cape that may enhance business performance. The research was carried out amongst SMEs in the Eastern Cape however the results and recommendations of the study can be applied to SMEs in other parts of the country. The research methodology employed in this study was a quantitative approach. A web-based survey was distributed to potential respondents. The criteria used in identify potential respondents for the purpose of this study was that, the SME had to have less than 200 employees and been in business for more than three years. A combination of snowball and convenience sampling was used to select the sample. The researcher developed a conceptual framework using the literature as basis. The survey was distributed to 40 potential respondents. A total of 21 responses were received which translates to a 51 percent response rate. Data analysis was performed by means of descriptive and inferential statistics. The study confirmed the existence of a significant relationship between the independent variables being human resource management, accounting, technology, internal controls and entrepreneurial traits and the dependent variables being business performance. The study affirmed the notion that certain business practices and entrepreneurial traits should be prevalent in a SMEs business in order to enhance business performance. The findings of this study are such that these business practices should be present however the variables highlighted here are not absolute as there are other business practices that are of equal importance.

  • Description: In this project, the researcher evaluates revenue collection and allocation challenges faced by South African Municipalities in the case of NDLAMBE Local Municipality and this research project consist of five Chapters. Chapter one introduces and outlines the setting of the study and also provides the problem statement, research questions, research objectives and significance of the study. The chapter further clarifies the key concepts and terms that were used in the study, delimitation and limitations of the study. Chapter two provides a critical discussion of the concept of revenue collection and allocation, focusing on the various perspective of revenue. A source of municipal revenue and revenue collection and allocation model is explained as well as theoretical framework that guides it. Chapter three gives an account of the research design and methodology used in the study and in this study the researcher used the qualitative research approach as a data collection technique and document surveys were used because it is cheap and it saves time. The chapter also highlights the revenue collection and allocation applicable to the study and conclude by discussing the data analysis techniques that were used in the empirical study. Chapter four dealt with the data analysis of data collected presentation and discussion of the results and the researcher analyzed data using the filtering technique and content analysis. Chapter five drew conclusions and made scientific recommendations based on the research findings.The municipality is largely dependent on grants from upper spheres of government and generate less than 20 percent of current expenditures from own resources. As a whole, the revenue collection and allocation challenge of the NDLAMBE Local Municipality, given the current scenario of flows, is a reason for concern. Due to historical and political factors, local governments in South Africa differ substantially in terms of potential revenue base, but it may be that in many cases potential revenue is not exploited and that the high level of dependency on grants, high level of bad debts and lack of political will to be more self-reliant is the result of poor revenue in NDLAMBE Local Municipality.

  • Description: The neo-liberal restructuring of state assets and facilities, which has taken place internationally over the past three decades, as well as in South Africa, has been a matter of great controversy. Privatisation, in particular, has been a polarising issue, especially when applied to fields like healthcare. Supporters of privatisation view it as cutting costs, mobilising funding, expertise and innovation, resulting in improved delivery, and opening possibilities for a spread of ownership. Critics claim the process involves retrenchments, declining services for the (poorer) majority of people, and a focus on the elites as citizens become transformed into customers, and with any economic empowerment going to the already prosperous. This thesis examines these issues by looking at the privatisation of hospitals in South Africa, with a case study of the Netcare-Settlers Public Private Partnership (PPP) (also known as the Settlers Private Hospital) in Grahamstown, South Africa. Netcare is South Africa’s largest private hospital company, and also has substantial operations in the United Kingdom. The thesis sets out the context: a highly inequitable healthcare system in the country, the rise of privatisation in the apartheid and post-apartheid eras, and healthcare privatisation. In terms of the Netcare-Settlers PPP, the thesis examines how the PPP was structured and developed, focusing on the impact of the PPP on non-clinical operations. The thesis argues that the results of the PPP are mixed, that it has greatly improved areas like facilities, maintenance, cleaning and catering, performed less well in increasing the doctor/ patient ratio or in attracting specialists, and is associated with the widespread and problematic use of outsourcing of service workers like cleaners and security. Overall, the PPP has improved healthcare, with some effective sharing of resources between the public and private parts of the hospital, but also relies on a pool of relatively low waged, under-unionised, labour. In terms of the general debate over privatisation, the Netcare-Settlers PPP shows that both supporters and critics have some valid points, and that privatisation in practice is not an either/ or, black/ white, good/ bad proposition, but something more complex. The success and failure of PPPs depend on the details of the contracts, and these can be used to maximise the performance of both the public and private partners. Better contracts may help avoid the uneven results seen at institutions like the Netcare-Settlers PPP.

  • Description: This research is based on reflections of various practitioners and their views on how public participation processes may or may not contribute to effective EIA decisions. It is therefore grounded in what is described as practitioner-based research. To study comparative development activities effectively, one must draw on many disciplines and construct a balanced understanding of historical and contemporary development processes. No single conventional disciplinary area of research is able to integrate the issues of public participation, EIA and decision-making in the context of the current development debate. The emergence of Trans-disciplinary areas of research allows for such integration. The Africa Earth Observatory Network (AEON) institute creates the space for this study to achieve an integrated response to the question of the effectiveness of public participation in EIA and decision-making. This further creates the opportunity to contribute and expand the growing body of knowledge and literature of public participation in the earth stewardship science discipline. Making use of triangulation, this study fulfils four major tasks: firstly, an assessment is made on the historical and theoretical importance, process and outcome of both EIA and public participation internationally and in South Africa. Secondly, three prominent case studies (i) the Coega IDZ, (ii) the Pondoland N2 Toll Road, and (iii) the anticipated Hydraulic Fracturing in the Karoo each focusses on concerns of an environmental, socio-economic, and political nature to assess if the public participation process has had influence, if any, on the final decisions for these projects to go-ahead. Thirdly, a survey was conducted to establish the views and perceptions of practitioners in the EIA and public participation domain on the effectiveness of public participation in EIA processes. Lastly, face-to-face interviews were conducted with various ‘pracademics’, i.e. consultants, practitioners, government, and non-governmental officials to establish their views on how public participation may or may not influence EIA decisions. Utilising the International Association for Public Participation’s (IAP2) participation spectrum as an evaluation tool, this research explores thirteen key criteria normally attributed to effective public participation. This provides a scale (inform, involve, consult, collaborate) to assess whether public participation in EIA in South Africa is least effective (inform) or most effective (collaborate). My research confirms that in South Africa an enabling environment to address impacts on our environment is emerging. One of the main challenges remains putting in place robust, clear and effective regulations, models or approaches that provide for effective public participation and decision-making in EIAs. My research also suggests that the legislation on which EIA is based cannot by itself guarantee the effectiveness of public participation processes. In practice, EIA is an institutional process of power division between different actors, and the practitioner or ‘pracademic’ has to play a more fundamental role to ensure effectiveness and fairness in the public participation process. Academic commentators should therefore call for new approaches that emphasise collaborative interaction between decision-makers and the public as well as deliberation amongst participants.

  • Description: Mycobacterium bovis and other species of Mycobacterium tuberculosis complex (MTBC) can result to a zoonotic infection known as Bovine tuberculosis (bTB). MTBC has members that may contaminate an extensive range of hosts, including wildlife. Diverse wild species are known to cause disease in domestic livestock and are acknowledged as TB reservoirs. It has been a main study worldwide to deliberate on bTB risk factors as a result some studies focused on particular parts of risk factors such as wildlife and herd management. The objectives of this study were to design questionnaires from commercial farms and smallholding farms; isolate and identify MTBC from collected samples using culture and PCR assays recovered from Fort Hare, Middledrift and Seven star dairy farms; and assessing genotypic drug resistance through detection of mutations conferring resistance to INH and RMP associated with first line treatment for MTBC infection. Questionnaires were administered to thirty (30) smallholding farm owners in the two villages (kwaMasele and Qungqwala) and three (3) three commercial farms (Fort Hare dairy farm, Middledrift dairy farm and Seven-star dairy farm). Detection of M. tuberculosis complex was achieved by Polymerase Chain Reaction using primers for IS6110; whereas a genotypic drug resistance mutation was detected using Genotype MTBDRplus assays. Nine percent (9 percent) of respondents had more than 40 cows in their herd, while 60 percent reported between 10 and 20 cows in their herd. Relationship between farm size and vaccination for TB differed from forty-one percent (41 percent) being the highest to the least five percent (5 percent). The highest number of respondents who knew about relationship between TB cases and cattle location was ninety-one percent (91 percent). Approximately fifty-one percent (51 percent) of respondents had knowledge about wild life access to the farms. Relationship between import of cattle and farm size ranged from nine percent (9 percent) to thirty-five percent (35 percent). Cattle sickness in relation to farm size differed from forty-three (43 percent) being the highest to the least three percent (3 percent); while thirty-three percent (33 percent) of respondents had knowledge about health management. Respondents with knowledge about the occurrence of TB infections in farms were forty-eight percent (48 percent). The frequency of DNA isolation from samples ranged from the highest forty-five percent (45 percent) from water to the least twenty-two percent (22 percent) from soil. Fort Hare dairy farm had the highest number of positive samples forty-four percent (44 percent) from water samples; whereas Middledrift dairy farm had the lowest positive from water, seventeen percent (17 percent). Twelve (22 percent) out of 55 isolates showed resistance to INH and RMP that is, multi-drug resistance (MDR) and nine percent (9 percent) were sensitive to either INH or RMP. The mutations at rpoB gene differed from 58 percent being the highest to the least (23 percent). Fifty-seven percent (57 percent) of samples showed a S315T1 mutation while only 14 percent possessed a S531L in the katG gene. The highest inhA mutations were detected in T8A (80 percent) eighty percent and the least was observed in A16G (17 percent). The results of this study reveals that risk factors for bTB in cattle and dairy farm workers is a serious issue abound in the Eastern Cape of South Africa; with the possibility of widespread dissemination of multidrug resistant determinants in MTBC from the environment.

  • Description: Aim: To determine the level of knowledge and practice of the nurses in the prevention and control of nosocomial infection in the intensive care units and make recommendations aiming at bridging the gap identified. In this study, the level of knowledge and practice of nurses in the intensive care units was described and its relationship with the demographic characteristics was examined utilising a quantitative approach. A quantitative descriptive design was used to examine and describe knowledge and practices of intensive care nurses with regards to prevention and control of nosocomial infection. One hundred and thirty (130) nurses participated in the study taken from the intensive care units of the five (5) state hospitals of the Eastern Cape Province. A self-designed questionnaire with close-ended questions was utilised comprising of dichotomous questions, with ‘yes’ or ‘no’ measuring knowledge nurses have and a Likert scale that measured knowledge with regards to clinical practice utilised in the prevention and control of nosocomial infections. The following ethical considerations were addressed by the study: ethical clearance, permission to conduct the study, informed consent from participants, anonymity and confidentiality and respect of individual autonomy. Findings: The respondents showed encouraging agreement with the different practices that should be followed in order to prevent spreading of nosocomial infections in their units. This knowledge suggests that the problem of infection control in ICUs may be related to the individual characteristics of the profession as opposed to being institutional. Limitations: Not all the intensive care units of the Eastern Cape hospitals were included due to challenges of time, finance and geographic factors. Recommendations: The following recommendations were made: Orientation programme to all new staff coming into the ICUs including infection control policies and guidelines; Involvement of the ICU staff in the development of infection control policies so as to ensure ownership and ultimate compliance; The employer must ensure that all resources for infection control and prevention are available and accessible to the health care workers at all times to ensure compliance. , Thesis (MCur) -- University of Fort Hare, 2015

  • Description: This is a qualitative study which focuses on how Liberty Life Swaziland distributes microinsurance to the bottom of the pyramid within Swaziland. Using stratified purposive sampling, this study identified 5 managers within Liberty Life and 4 managers from brokerages and affinity partners who had a minimum of 3 years’ experience in distribution of microinsurance. Semi-structured and in-depth interviews were conducted by the researcher with these managers. Interviews were stopped when there was data saturation. To induce emerging themes from the data, open-coding and constant comparison technique was used. Findings in this study reveal that to distribute microinsurance to low income households, Liberty Life objectives are to; (1) provide relevant solutions in a cost effective manner, thus keeping premiums as affordable as possible, (2) provide simple products which are easy to understand by customers, (3) make services accessible, and (4) make doing business easy. In this regard, Liberty Life distribution strategy is to partner with bulk retailing entities that have a client base they already service and benefit from nationwide presence and infrastructure. Lastly, the perspectives of both internal and external stakeholders in microinsurance are discussed to evaluate the challenges and successes experienced in implementing the distribution strategy. This study is valuable to critically understand the current distribution strategy from the viewpoint of key intermediaries, but also pinpoint how efforts to achieve microinsurance distribution objectives can be enhanced. Lastly, the study recommends that; a selection criteria be set for distribution partners, partnership with mobile network operators, investment in continuous training of distribution partners and knowledge sharing between Liberty and intermediaries to cease the opportunity at the bottom of the pyramid.

  • Description: The dynamism of human needs and the inability of the state and governments to guarantee a satisfactory access to, as well as consumption of private and public goods and services have prompted an up-sprung of alternative institutions such as the Non-Governmental Organizations. This study sought to evaluate selected NGOs in provision of health, education and housing services in Alice Township of the Eastern Cape Province. The study had the following specific objectives: to evaluate the role of selected NGOs in Alice in the provision of health, education and housing services; to examine the successes and possible gaps of selected NGOs in provision of aforementioned services; to examine the relationship between the NGOs and the government in provision of above mentioned services; and finally to establish the strategies that can be adopted to enhance NGOs’ capabilities in services delivery. To achieve these objectives, the study utilized mixed methods research approach, with an explorative and a mini-survey design. Non-probability sampling methodology was used and specifically purposive sampling was used to get a sample of 115 research participants and respondents. Data collection was cross- sectional and was facilitated by the use of in-depth interviews using semi-structured interviews and questionnaires. Data was analysed using both qualitative and quantitative approaches, and the results were triangulated to answer the research problem. The study was premised on the Public-Private Partnership (PPP) model of service delivery, and diverse literature was sought to strengthen the findings. The study revealed that: the females were more active in welfare sector than men; the concept NGO posed a conceptual challenge to the research participants; high level of unemployment and low level of tertiary literacy among study participants was reported. Furthermore, NGOs in Alice provided health based services which included creating awareness, control and treatment of communicable and non-communicable diseases such as HIV/AIDS, tuberculosis, diabetes, psychological and palliative care, counselling and old age care services. Educationally, early childhood development services took the lion’s share. This is evidenced by an array of day care centres in Alice. Regrettably, there were no housing services offered by NGOs in the area. The findings also revealed diametrically opposed debates on successes of NGOs in Alice, with some not seeing the success while others indicated some successful milestones. Notably, the NGOs in Alice suffered a paucity of resources which included: lack of funds, unskilled and inadequate staff, infrastructural and technological challenges, lack of transport facilities among others. The study also indicated a sour relationship between the government and the NGOs. Despite this, the NGOs were reported to adhere largely to the policy guidelines postulated by the government. Moreover, the government was the major funder of the most NGOs in the area of study. The findings revealed that fundraising skills were needed to bolster the NGOs financial muscle towards the achievement of project implementation. The state of infrastructure also needed to be addressed as well as scaling up the NGOs services to reach to a greater section of the society, Partnerships, collaborations and networking for NGOs would enable NGOs services delivery. The study also recommended: inclusivity in the welfare sector, establishment of vibrant housing NGOs in Alice, empowerment approaches to service provisioning, proper visibility of the NGOs in the community, systematic and regular promotion of training among the NGOs’ staff, sound and up to date harmonised policies, mutually designed partnerships, collaborations and networks, flexibility of donor funding approaches, intensive and extensive government support to NGOs, periodic scientific inquiry on NGOs operations and finally recommendation is made for further research in the area under the study. Conclusively, it is critical that NGOs in Alice are doing their best compared to their resource base and therefore, the government should study the environment of the NGOs in the area with the hope of coming up with plausible and pragmatic ways of bolstering their operations. , Thesis (M Soc Sc)(Social work) -- University of Fort Hare, 2015

  • Description: This anthology outlines case studies which have emerged from an approach to evaluation which enables individual academics to practice a degree of autonomy in how they determine their own evaluation agendas, methods and approaches. This has enabled individual cases of both rigour and creativity when it comes to the collection of data and generation of feed- back on their teaching and/or courses, particularly in relation to transforming curricula responsively; enabling student voice and increasing student ownership; and creating spaces for practices to be challenged. The purpose of the case studies is pedagogic and to illustrate a range of practices and principles. For the sake of clarity some of the details have been omitted or slightly changed.

  • Description: Waste waters can be sources of pollution to surface water and the environment with severe implications for public health. Most treatment plants in the Buffalo City Municipality in the Eastern Cape Province discharge their treated effluent into the surface waters which directly and indirectly impacts on the quality of surface waters in the region. The objective of this study was to determine the microbiological and physicochemical qualities of the final effluents of two wastewater treatment plants in the Buffalo City Municipality in the Eastern Cape Province of South Africa over a period of 12 months (September 2012 to August 2013). The qualities of the final effluents of WW-Ama Wastewater Treatment Plant with respect to phosphate (3.9 mg/l - 20.6 mg/l), free chlorine (0.05 mg/l - 0.71 mg/l), chemical oxygen demand (COD) (4.7 mg/l - 211 mg/l), and faecal coliform (0 - 2.92 × 104 CFU/100 ml) were not in compliance with the permissible limits set for effluent discharged to surface water by South Africa guidelines for effluent discharge. Other physicochemical parameters like biological oxygen demand (BOD) (2.2 mg/l - 9.0 mg/l), total dissolve solid (TDS) (253 mg/l - 336.3 mg/l) and turbidity (4.8 NTU - 43.20 NTU) with no SA regulatory set limits were compared to other regulatory standards and they do not comply with the limits. Also, at the second WWTP’s, the WW-Dim Treatment Plant effluent quality for free chlorine (0.06 mg/l - 7.2 mg/l), BOD (0.1 mg/l - 7.4 mg/l), and turbidity (4.02 NTU - 24.3 NTU) also did not comply. For microbiological qualities, counts of presumptive E. coli and Vibrio ranged between 0 - 2.92 × PROFESSOR ANTHONY I. OKOHAntibiogram of the bacterial isolates were determined using the disk diffusion method. A total of 107 confirmed E. coli and 100 confirmed Vibrio spp. were used for this assay. Results of antibiotic sensitivity test revealed that 63.6% of the E. coli isolates were resistance to ampicillin while 49.5% were resistant to tetracycline and cephalothin. The least resistances were observed against gentamicin (3.7%) and cefotaxime (1.9%). No resistance was observed against meropenem. For the Vibrio spp, resistance was most frequently observed against tetracycline (38%) ampicillin (26%), chloramphenicol (16%), cefotaxime (14%), trimethoprim-sulfamethoxazole (13%) and the least resistance observed was against ciprofloxacin (1%). This study demonstrates that poorly treated wastewater effluent can be a source of eutrophic water with high nutrient levels and pathogenic bacteria and enteric viruses as well as antibiotic resistance determinants that could impact negatively on human health. The finding of this study also suggests that WWTPs have to be properly monitored and controlled to ensure compliance to set guidelines. This could be attained through the application of appropriate treatment processes, which will help to minimize possible dangers to public environment health.

  • Description: Despite its cryptic habitat and habits, light and transmission electron microscopy has revealed that like many other siphonariids Siphonaria compressa, the smallest species of this genus, possesses lateral pedal glands. The pear-shaped glands (about 120 µm long Ã? 70 µm maximum diameter) open via a pore, and are multicellular with three types of secretory cell that surround a central lumen. The glands of this minute pulmonate limpet are similar in structure to its larger relatives, suggesting that they are defensive in function.

  • Description: Lack of access to essential medicines has proven to be a persisting problem which is in conflict with the goal of realising the right to health envisaged by the South African constitution and international human rights instruments. With more than twenty years of democracy, South Africa is still plaguing with a multiplicity of pandemics such as HIV and AIDS, cancer, malaria, tuberculosis, among others, leading to premature death and untold suffering of the people. According to a 2015 United Nations AIDS (UNAIDS) Gap report, South Africa is still regarded as the epicentre of HIV and other infectious diseases. The 2015 UNAIDS Gap report states that South Africa has more women than men living with HIV and AIDS. The report further indicates that the impact of this pandemic is worsened by the inaccessibility of essential medicines that are vital for life saving. This dissertation posits that the epidemiological health crisis described above can be largely eradicated through the utilisation of the right to health. The right to health, according to this dissertation, contains a legal and transformative power which can be utilised to limit the negative impact of patent laws on access to essential medicines in South Africa. This dissertation validates the long held view that World Trade Organisation (WTO) intellectual property laws have contributed to the inaccessibility of essential medicines through causing patent ever greening, patent linkages and pharmaceutical company’s monopolies. Consequently, many marginalised groups in South Africa lack access to essential medicines owing to the higher prices charged for such medicines thus violating the right to health, life and other fundamental human rights. The right to health which is the immediate right infringed when there is lack of access to essential medicines form the core theme of this dissertation. This dissertation argues that access to essential medicine is a fundamental part of the right to health protected under international and national human rights instruments. This dissertation further argue that the right to health imposes obligations which requires South African government to take reasonable legislative and other measures, within its available resources, to provide access to essential medicines. The dissertation‘s key contribution is its proposed solutions on how to ensure that patents rules in South Africa are tamed with obligations consistent with the right to health. If properly implemented, these solutions have the potential to give greater specification to the normative commitments imposed by the right to health in the patent claims scenarios.

  • Description: The current landscape of South Africa’s education system is one riddled with many challenges. Young people studying in this unfavourable climate have become disillusioned by the failing system and this has resulted in negative attitudes towards schooling. A shortage of teaching personnel and a lack of resources further exacerbate the situation. In recent years however, it has been found that a significant number of young people seem to have “beaten the odds”, in spite of these unfavourable conditions as they have seen themselves being granted entry into tertiary institutions. The dearth of information on academic resilience and the increased number of “educational success stories” led the researcher to embark on this qualitative study. The aim of this exploratory, descriptive and contextual research study was: to enhance understanding of the academic resilience and subsequent academic success at school, as experienced by first year NMMU students from disadvantaged communities, by exploring their constructions of academic resilience. Bronfenbrenner’s Ecological Systems Theory as well as Resilience Theory was used to examine the phenomenon of academic resilience. Purposive sampling techniques was utilised to draw participants within the NMMU’s School of Behavioural Sciences and data was collected by means of narrative accounts by participants. The two phases of narrative analysis were applied to analyse the data collected and Guba’s model for trustworthiness was used to verify the data. The findings of the study indicated that both intrinsic and extrinsic factors contribute to the fostering of resilience.

  • Description: This qualitative study using a phenomenological design, aimed at exploring and describing and exploring the experiences of HIV positive clients defaulting Isoniazid Preventive Therapy services in the Bhisho Primary Health Care Services. The emphasis was on the factors leading clients to default. An in- depth unstructured face to face interviews were done on 14 participants from 4 clinics or facilities under Bhisho Primary Health Care Services. From the respondents’ responses it can be noted that work and family related issues, ignorance of patients, side effects, and negligence of nurses and denial of HIV status were identified as reasons for defaulting. Having knowledge about the treatment and health providers’ attitudes to patients also played a role in patients defaulting their treatment.Many suggestions were then put forward by the respondents to curb defaulting among patients. These included the use of text message reminders, not to discrimination HIV patients because of their status, to use consulting rooms for privacy and also nurses and caregivers to control their attitudes when dealing with patients.

  • Description: This qualitative study explores the experiences of incarcerated women who have perpetrated intimate partner homicide (IPH) and had been exposed to intimate partner violence (IPV) in their relationships. The study further explores women’s experiences of IPV, in particular those which motivated them to perpetrate IPH. The study examines how factors associated with IPV affect women to the point of responding with such lethal IPH. Additionally, it explores whether or not women feel remorse for their actions of IPH. The current study falls within an interpretive research paradigm and employs interpretative phenomenological analysis (IPA) as its theoretical framework. The researcher selected IPA as it works well in understanding and describing participants’ experiences. Semi-structured face to face interviews were conducted with nine women incarcerated for IPH. The findings of the study were analysed using the IPA approach. Three main themes emerged from the analysis: mainly all women reported to have experienced IPV in their respective relationships with the deceased, all, except one woman, reported that their partners had committed infidelity, the women also reported to have experienced much disappointment in gaining assistance from the judicial system. Therefore, on-going IPV including death threats resulted in fear; infidelity resulted in tremendous emotional and psychological strain, as well as feelings of betrayal; and perceived lack of support from the judicial system all appeared to have motivated women to perpetrate IPH with the majority indicating remorse.

  • Description: Experiences of women regarding unexpected neonatal resuscitation were studied in this research. The objective of the study was to explore and describe the experiences of labouring women whose babies required unexpected resuscitation at birth. Recommendations were made based on the findings of the study. Labour and birth do not always go as well as expected as deviations could happen at any of the four stages of labour. Midwives tend to focus on the neonate when resuscitation is needed and leave the mother unattended and wondering what is happening as they rush away with the neonate. The situation motivated the researcher to conduct the study. The focus was on the experience of during the time of resuscitation. The study is qualitative, and exploratory, descriptive, contextual and narrative research approaches were used to reach the objective. The research population included women who delivered in the identified site from six hours to six weeks post delivery period. Inclusion criteria were the following: Women must have attended antenatal care at least four times. Their pregnancies were categorized as low risk. The ages of the women were 18-35 years. Gestational age was 38-41 weeks. The neonate should have been resuscitated successfully and admitted for observation in the nursery. Non-probability, purposive sampling was used. Data was collected by conducting semi-structured one-on-one interviews using a tape recorder. The site for the study was a public hospital, and the managers and operational midwives were used as gatekeepers. Fifteen participants gave permission to participate in the study willingly and were interviewed individually and anonymously. The interviews were transcribed, and Creswell’s data analysis spiral image was used. The period for data collection was seven months in one academic year. An independent coder’s services were utilized to increase the trustworthiness of the findings. The trustworthiness of the study was also ensured by conforming to Lincoln and Guba’s model of trustworthiness. Strategies used to ensure trustworthiness were credibility, transferability, dependability and conformability. The researcher maintained the ethical standards for conducting research by adhering to ethical principles, such as human rights, beneficence and justice. Confidentiality was maintained by using numbers instead of names, and only the researcher knows the participants’ names. Only the researcher, supervisor and the independent coder have access to the information. The data is kept in a locked cabinet and will be kept for the next five years following the publication of results. Two main themes emerged from the data analysis with each having two sub-themes Mothers verbalized varying emotions regarding their neonates’ inability to breathe properly. Mothers verbalized the importance of receiving support and information from midwives. To optimise the discussion of research findings, direct quotes were used from the raw data of interviews to support the description of experiences. Recommendations for midwives were to prepare the pregnant women during antenatal care for unexpected emergencies during labour and to reinforce this information on admission when labour commences. Managers are to update the guidelines on maternity care and the health education checklist. Nursing schools should train student midwives in debriefing and counselling skills. Both study objectives were successfully met.
