- Description: Access to clean and safe water is essential for the survival of human beings. Pollution of freshwater sources constitutes a major problem hindering access to safe water for drinking and other domestic uses. Wastewater effluent discharges often impact the microbiological qualities of surface waters with its attendant health and environmental problems. This study evaluated the microbiological qualities of the discharged effluents of four selected wastewater treatment plants in Amathole and Chris Hani District Municipalities of the Eastern Cape Province over a twelve-month sampling period. Microbiological analysis (faecal coliform, Escherichia coli and Escherichia coli O157:H7) was done using standard methods and polymerase chain reaction method was used to confirm identities ofbacterial isolates. Presumptive bacteria counts ranged as follows: faecal coliforms 0 to 1.6 × 103 CFU/100 ml, E. coli 0 to 1.4 × 103 CFU/100 ml and E. coli O157:H7 0 to 9.6 × 102 CFU/100 ml. Forty eight percent (305/626) of the presumptive E. coli isolates were confirmed using species-specific uidA gene which code for β-glucuronidase enzyme in E. coli. Antibiotic susceptibility profile of the isolate using a panel of 10 antibiotics shows 100% (150/150) resistance to antibiotics rifampicin and penicillin G while 49.3% (74/150) of the isolates and 46.7% (70/150) were susceptible to streptomycin and cefotaxime respectively. Multiple antibiotic resistance phenotypes (MARP) of the isolates showed resistance to two or more test antibiotics while the calculated multiple antibiotic resistance index (MARI) for the tested isolated is 0.49. The detection of potentially pathogenic E. coli in the final effluents suggestspotential danger to the receiving water bodies where the effluents are discharge. The high MARI valued obtained in this study indicates that the isolates are form environment where the tested antibiotics are being used and may further lead to the spread of multiple antibiotics resistance among other pathogens that may be present in the same environment.

- Description: The study is about evaluating supervisor performance at Transnet Port Terminals (TPT) and the impact it has in the business world in general. The aim of the study was to evaluate the quality of supervisors at Transnet Port Terminals (TPT) in the Eastern Cape. The sample size of 43 supervisors working at TPT from different departments like operations, planning, key accounts and procurement participated in the study. The sampled supervisors are between the ages of 20 and 59 years and was composed of females and predominantly males. The data was gathered through a questionnaire that was designed particularly to address the lack of quality of supervisory support at TPT. The response from respondents were tied to themes that were constructed, which are: (a) organisational goals; vision and management competencies; (b) communication; (c) performance cycle-setting of goals; (d) supervisor/supervisee performance conversation; and (e) supervisory development programme. The literature gathered and deliberated on in the literature review emanate from different authors in the form of books, journals and treatises. The empirical results were linked to theories gathered from different authors. Research findings were used to curb the issues identified, which will be beneficial to both TPT and its employees. The recommendations were submitted to the company to look at developing an in-house supervisory programme, capacity building internally and creating platforms for effective communication.

- Description: Certain areas in the world still depend on the receiving water bodies as sources of domestic water and for recreational purposes. The discharge of poor quality effluents from wastewater treatment plants can impact negatively on these water bodies, as they can act as vehicles for pathogens to the environment, posing a threat to humans if such water is used without precaution. Vibrio species are amongst those pathogens that can survive wastewater treatment processes, ending up in the environment, hence the aim of this study was to evaluate the final effluents of some wastewater treatment plants as sources of vibrio pathogens. Five wastewater treatment plants (WWTP) located in Amathole and Chris Hani District Municipalities in the Eastern Cape were used in this study. Samples were collected monthly from September 2012 – August 2013 and analysed using the standard membrane filtration technique. Yellow and green colonies on TCBS agar were enumerated as presumptive Vibrio species and expressed as CFU/100ml for each plant. Colonies were later picked based on their phenotypic characteristics, sub-cultured on fresh TCBS agar to ascertain purity. These presumptive isolates were then subjected to Gram staining and Oxidase test. Gram negative and Oxidase positive isolates were selected for further confirmation using Polymerised Chain Reaction (PCR). PCR was also employed for characterisation of Vibrio into three species viz V. parahaemolyticus, V. fluvialis and V. vulnificus. Antibiogram profile of the characterised species was then determined together with the presence of relevant antibiotic resistance genes Vibrio densities for the twelve month period ranged between 0 - 1.48×104 CFU/100ml with two of the plants located in East bank and Queenstown characterized by extremely high counts and one plant( Reeston) with very low counts.Three hundred presumptive Vibrio isolates were screened for identity confirmation. Of these, the dominating species found was V. fluvialis (28.6%) followed by V. vulnificus (28%) and the least was found to be V. parahaemolyticus (11.6%). The remaining unidentified 31.6% were suspected to belong to other Vibrio species not covered within the scope of this study. All the confirmed isolates i.e., V. parahaemolyticus, V. vulnificus and V. fluvialis were susceptible to imipenem, gentamicin and meropenem and resistant to only tetracycline. Between 60-100% of the V. parahaemolyticus isolates, 7.1% to 100 % V. vulnificus isolates and 2.5 to 100 % V. fluvialis showed resistances to polymixin B, sulfamethazole, erythromycin, penicillin G, chloramphenicol, trimethroprim and trimethroprim & sulfamethazole. Antibiotic Resistance Genes that were assessed included dfRA, SXT, floR and Sul2 varying in proportion with each species showing diversity in the Vibrio community. The dfR A gene was detected in all the V. parahaemolyticus isolates while floR gene was not detected in any of the isolates belonging to the three species. The distribution of sul2 gene cut across the species being 1% (1) in V. fluvialis, 3% (1) in V. parahaemolyticus and 4% (3) in V. vulnificus. The SXT gene was only determined in V. parahaemolyticus. It is clear that the final effluents of the selected plants are reservoirs for Vibrio pathogens as well as antibiotic resistance genes in the environment. The isolation of Vibrio from WWTP shows that this pathogen is in circulation in some pockets of the population. Therefore, wastewater treatment plants need to be properly monitored to ensure that they comply with set guidelines.

- Description: The focus of this study is to explore three key aspects of learners’ multiplicative proficiency: the nature of learners’ conceptual understanding of multiplication, the nature of learners’ numeracy dispositions (in the context of learning multiplication), and the relationship between conceptual understanding and productive dispositions in the context of multiplication. The study used a qualitative case study approach to gather rich data in relation to these. In the study a purposively selected sample of six Grade 4 learners was used from the same school: two high, two average, and two low performers. Kilpatrick, Swafford, and Findell (2001) define conceptual understanding as a functional grasp of mathematical ideas and its significant indicator is being able to represent mathematical situations in different ways and knowing how different representations can be useful for different purposes. They then refer to productive disposition as the ‘tendency to see sense in mathematics, to perceive it as both useful and worthwhile, to believe that steady effort in learning mathematics pays off, and to see oneself as an effective learner and doer of mathematics’ (p.131). Individual interviews were conducted using Wright, et al.’s (2006) instrument for exploring the nature of students’ conceptual understanding of multiplication. Wright, et al. (2006) argue that the topics of multiplication and division build on the students’ knowledge of addition and subtraction, and also multiplication and division provide foundational knowledge for topics such as fractions, ratios, proportion and percentage, all of which are core and essential areas of mathematical learning typically addressed in the primary or elementary grades. Researchers agree that learners have to be exposed to various strategies so that they are able to see that there is a difference between additive reasoning and multiplicative reasoning. In order to classify learners’ conceptual understanding of multiplication an analysis of the data was done and learners were allocated levels according to the Wright, et al. (2006) levels of achievement. For the classification of learner dispositions, the data was analysed in terms of the elements of productive disposition as defined by Kilpatrick, et al. (2001) and Carr and Claxton (2002). The key findings of the study indicate that for conceptual understanding most of the learners depended on using concrete materials in solving multiplication and they also used basic strategies and methods. The findings for productive dispositions were that most of the learners saw themselves as competent in doing multiplication but the aspect of sense making and steady effort was less developed. The findings for the relationship between conceptual understanding and productive disposition were that both strands have a mutual relationship in which one helped the other to develop.

- Description: The relationship between a country’s real exchange rate (RER) misalignment and economic growth has attracted much attention from both academic and policy perspective. This study examines the relationship between the exchange rate misalignment and economic growth in South Africa, by specifically looking at the fundamental determinants of the real exchange rate and the impact of the misalignment on economic growth for the period 1980 to 2012. This study employs the Johansen cointegration technique and the Vector Error Correction Model. The empirical results revealed that terms of trade, government consumption expenditure, net foreign assets, broad money supply and technological productivity are important factors in determining the RER in South Africa. In addition to the misalignment variable, terms of trade, government spending, private business investment and broad money supply were also found to influence economic growth in South Africa. This suggest that authorities can influence the behaviour of the exchange rate in South Africa through altering one of its fundaments. The results suggest that a RER misalignment has a negative effect on economic growth in South Africa. Thus policies aimed at maintaining an equilibrium RER should be pursued.

- Description: Grocery retailers are faced with many challenges. Among them are competition, employee theft and deviant consumer behaviour (DCB). Deviant consumer behaviour violates generally accepted norms of consumer behaviour in retail settings. There has been a lot of research conducted on DCB and different terms and phases have been used to describe the behaviour, ie “dysfunctional customer behaviour”, (Daunt and Harris, 2012), “aberrant consumer behaviour” (Fullerton and Punj, 1993) and “consumer misbehaviour” (Fullerton and Punj, 1997). However, the research conducted on how the behaviour affects retailers, particularly grocery retailers has been limited. The primary objective of this study was to examine how DCB affects grocery retailers in Nelson Mandela Bay Municipality. More specifically, the relationship between DCB (dependent variable) and independent variables - impact on profits (RPROF), impact on inventory (INV), impact on grocer security (SECU), impact on employees (EMPL), impact on customers (CUST) and measures to minimize or stop DCB (STOP) was established. Questionnaires were used as a measuring instrument. Out of the 100 questionnaires distributed, 70 were usable. The empirical results showed that there is a significant relationship between DCB and the independent variables. Recommendations on how best the stores can deal with DCB were made and measures to minimize or stop DCB were presented. Recommendations for future studies were also presented.

- Description: The general Australian workforce is becoming increasingly reliant on agency staff due to the diminishing of full-time jobs and the rise in part-time jobs since the recession of 1991-1992. This pattern is also seen in Western countries such as America and the United Kingdom (Peerson et al., 2002:505). The excessive costs of health service adopting a 100% staffing model has created the use of agency nursing to help meet fluctuating and unpredictable health care demands in Australia and overseas; agency staff are used to meet the shortfalls in staff-patient ratios (Peerson et al., 2002:505). Hurst & Smith (2011:287) agree that agency nurse staffing form a large part of the health service in the UK and state that this was unlikely to change because of recruitment and retention problems, high absenteeism, and staff wanting to work casually. In their study, they identified three types of agency nurses: A bank nurse – the hospital’s own employees or those supplied by NHS Professionals, who work when required, usually at short notice; agency nurses provided by commercial organisations, who are equally flexible but less familiar with the ward patients and procedures; and permanent ward staff working paid overtime. In South Africa, this also remains a problem in public and private institutions. The World Health Organization (WHO) states that the minimum ratio for nurses to population is 200:100 000 or 500 people per nurse. According to South African Nursing Council statistics of nursing manpower as at the end of 2008, South Africa has 437 nurses for every 100 000 people. This assumed that all nurses registered with SANC are working in South Africa at the time. Therefore, if the assumed number of staff not working in South Africa is subtracted, the ratio can increase to between 600 and 678 people per nurse (WHO, 2006). Joubert (2009:2) shows that a shortage of nurses contributes to deaths in hospitals in South Africa that would otherwise have been avoidable. The use of agency staff is becoming an appropriate means of providing cost-effectiveness and flexibility to staffing needs.

- Description: Fifty percent of the learning of student nurses takes place within the clinical learning environment. It is in this environment that nursing students are expected to apply their knowledge, learn new skills, and achieve the required learning outcomes and proficiencies. Nursing program Me s differ significantly, so students ‟practice will vary depending on where they are studying and their practice will develop as the level of proficiency increases, and may also vary depending on the context of placement. Gopee (2008:7) elaborates on the fact that mentoring enables student nurses to gain clinical skills during placements and serves a formal role whereby teaching and practice facilitate professional learning within the healthcare system. The study was undertaken with the aim to describe experiences of college students regarding the mentoring role by registered nurses in the Public Services of the Eastern Cape. The objectives of the study were to explore and describe experiences of college students, regarding the mentoring role of registered nurses in Public Services of the Eastern Cape, to analyse the results and to make suggestions from findings that were obtained. A qualitative, exploratory, descriptive and contextual design was used for this study to explore and describe the experiences of the college students regarding the mentoring role of registered nurses in the Public Services of the Eastern Cape, South Africa. The researcher studied the population of student nurses in the public nursing college in the Eastern Cape at the East London Campus. Purposive sampling which is referred to as a judgmental approach was used. Data were collected by means of focus group interviews. An interview schedule with an unstructured questionnaire was used to investigate and explore information gained from the participants. This study consisted of a total of five focus groups that were recruited from fourth-year nursing students at the East London campus who volunteered to be part of the study. The total number of participants was 31. Data were analysed using v Tesch‟s method of analysis for qualitative research. Two major themes emerged, revealing positive experiences of students with regard to mentoring and negative experiences of students regarding mentoring. After exploring and describing the experiences of college students regarding the mentoring role played by registered nurses in the Public Services of the Eastern Cape, it was concluded that that there is a lack of mentoring, coupled with negativity, by registered nurses which results in many challenges. Recommendations included: Motivation for integration and collaboration; interactive working relationships; introducing a well-established orientation programme; a well-structured clinical teaching programme and procedure manuals; reinstatement of clinical preceptors, clinical objectives and time frames; identify in clinical staff who will mentor student nurses; instituting in-service training programmes and workshops; introduction of peer mentoring; and establishment of set times for routine clinical ward rounds.

- Description: Labour pain seems to be a challenge to the most of the labour wards/units. The birthing pain is non-avoidable but could be managed. Labouring women are sometimes limiting themselves to their beds as they are not coping well with the amount of pain they experience and this behaviour affects the progress of their labour. Different methods of pain relief in labour are available but are sometimes perceived by labouring women and midwives as not effective. Mobility has been noted in several obstetrical and midwifery nursing literature as the best strategy to promote positive progress of labour thus limiting pain. The use of the birthing ball by labouring women appears to be serving the purpose of mobility in labour. The researcher of this study aimed to investigate the experiences related to the use of the birthing ball by the labouring women. The objectives of the study were: To explore and describe the experiences of women in labour related to the use of the birthing ball, and based on the findings of the study, to recommend guidelines for the midwives to manage the first stage of labour through the use of the birthing ball. The research design used was qualitative, descriptive, explorative and contextual in nature, utilizing the phenomenological approach. The research population consisted of women who had made use of the birthing ball during labour. Data collection consisted of one-on-one unstructured interviews and field notes. The question that the participants were asked was: “Tell me, how it was for you when you were using the birthing ball during labour?” Collected data was analysed according to Creswell’s data analysis spiral and the assistance of an independent coder. Following the data analysis, a literature control was undertaken to highlight the similarities to and differences in comparison between this and previous studies. Lincoln and Guba’s Model of trustworthiness was used in this study to enhance credibility of the findings. The four aspects that were considered were credibility, transferability, dependability and confirmability. The researcher ensured that the study was ethically correct by observing the principles of informed consent, confidentiality, anonymity and no harm done to participants. Three major themes and sub-themes were identified through analysis of the database. Participants’ experienced the birthing ball as a useful labour tool as: it relieves pain and allows them to relax and be comfortable, it helped to promote mobility during labour. Participants’ experienced the birthing ball as shortening the labour process as: it decreased the number of active pushes during delivery, it increased their contractions and resulted in a quick delivery. Participants experienced the use of the birthing ball as empowering during labour as: it introduces an element of fun which decreases their fear and resulted in a more positive labouring experience it allowed them to feel in control of their labour. Based on the findings of the study, conclusions were drawn, guidelines recommended and recommendations made concerning nursing research, nursing education and clinical practice.

- Description: Since the deinstitutionalisation of chronic mentally ill patients, there has been an increase in the number of relapsed chronic mentally ill patients who become acutely mentally ill and need to be re-admitted for acute care in psychiatric institutions. Professional nurses working at rural primary healthcare clinics find it difficult to care for these individuals because they lack the necessary knowledge and skills. Chronic mentally ill patients who have been admitted to acute care facilities are stabilised by rendering care, treatment and rehabilitation and then released into the care of the professional nurses working at rural primary healthcare clinics. These patients live in the community and have to make use of the primary healthcare clinics nearest to their homes to provide them with their prescribed medication and care. Furthermore the patients’ mental conditions do not always remain stable, possibly because of a knowledge deficit, at times about their mental status. Patients may become non-compliant, resulting in the recurrence of symptoms, and thus need to be re-admitted to the acute care facility. However, the problem leading to re-admission is not clear for all admissions. It may be that patients do not make use of the primary healthcare clinics. It also seems that the professional nurses in the primary healthcare clinics are unfamiliar in dealing with chronic mentally ill patients living in rural communities. The aim of this study was therefore, to explore and describe the experiences of these professional nurses in caring for chronic mentally ill patients living in a rural community. The researcher used qualitative, explorative, descriptive, and contextual research design. The research population consisted of professional nurses working at primary healthcare clinics. Non-probability purposive sampling was used to identify participants for inclusion in the study. Data collection was conducted using one-on-one, semi structured interviews, observations and field notes and interviews were tape-recorded and transcribed. Data analysis was conducted using Tesh’s method of content analysis to identify themes and sub-themes. A literature control was done to compare the findings to the current published research. Trustworthiness was ensured by using Gubas’s model (1985) of trustworthiness. A pilot study, conducted by interviewing a small sample prior to the start of the main study, determined whether the sampling and interviewing techniques of the researcher as well as the research questions were adequate for data collection. The researcher ensured that the study was of a high ethical standard by taking into consideration values that guide the principles of autonomy, beneficence, non-maleficence and justice. The findings of the study was categorised into three main themes and 13 sub-themes. The main themes were as follow: Professional nurses experience problems when they have to take care of psychiatric patients attending rural primary healthcare clinics. This theme had six sub-themes which were discussed in details in chapter three. The second theme was that professional nurses experience that psychiatric patients in rural communities experience problems which affected their well-being. This second theme has got five sub-themes which were discussed further in chapter three. The last theme was that professional nurses have positive experiences when caring for psychiatric patients in rural communities. This theme has got two sub-themes as well discussed further in chapter three.

- Description: The Kaponda Prospect represents a surface of 915.8 km² located at about 10 km south of the town of Lubumbashi and 33km NW of Kasumbalesa in the Democratic Republic of Congo (DRC). It lies within Neoproterozoic sedimentary rocks of the Katangan Supergroup in the Central African Copperbelt (CACB). In this province, copper mineralization occurs at different stratigraphic level with different associated alteration. Mineralization is of multistage origin from synsedimentary, diagenetic to post orogenic. Since the discovery of the CACB in the early 20th century, several exploration techniques have been used to delineate Cu deposits. A review and application of these methods including remote sensing, geological mapping, geochemical and geophysical surveys, and drilling, gives an insight of their effectiveness and limitation before analyzing their results from the Kaponda Prospect. The geology and structure of the Prospect is represented by a series of two NW trending disharmonic tight anticlines, locally domal, with cores occupied by either Roan Group or “Grand Conglomerat” Formation. These anticlines are separated by an open syncline made of Kundelungu rocks. Two mains direction of faults are recognized, the NW and NE trending structures. The latter direction are normal transfer faults which can serve as conduit for mineralization. They are related to the late orogenic extension of the Lufilian belt. However NE trending faults are believed to be associated to the climax of Lufilian folding or represents synsedimentary intergrowth faults. Exploration approach for sediment-hosted Cu within Kaponda Prospect, take into account the integration of all information derived from different techniques. Remote sensing is used as aid to geology. Landsat and Google earth images show lineaments that corresponds to lithostratigraphy boundary and domal anticline. Geological mapping identified reduced horizons which can potentially host mineralization, whereas analysis of structure measurements reveals the geometry of fold and direction of its axial plane and hinge. Statistical methods such as the main + 2 standard deviation, the frequency histogram and probability plot, together with experiential method are used to constrain and define Cu and Co thresholds values in soil samples. It appears that in this region, log-probability plot and histogram methods combined with spatial representation and the experience of the region, are the best practice to constrain and separate geochemical background from anomaly data. Ground and airborne magnetic, and radiometric images show specific signatures which map alteration and particularly lithostratigraphy such as “Roan” Group, “Grand Conglomerat” unit, “Nguba” cap carbonates and “Kundelungu” siliciclastic units. Analysis of faults interpreted from geophysical maps identified three major directions: E-W, NE-SW and NW-SE. The E-W faults are also interpreted as normal transfer faults such NE-SW structures, consistent with regional geological map. Although pole-dipole array of induced polarization (IP) survey was directly targeting disseminated Cu sulphide, its results suffer in responding to graphitic rocks and barren pyrite. Only relative small chargeable bodies need to be tested in drilling follow-up. A total of 15 targets have been generated through re-interpretation and integration of both geological mapping and remote sensing, geochemical and geophysical data, as well as existing drilling. Specific recommendations of follow-up works are advised for each type of target.

- Description: Exploration of indigenous knowledge and practices of the relatives of mental health care users regarding the management of mental disorders. This study was conducted to explore the management of mental disorders amongst the indigenous people of the Dedza District in Malawi. The government of Malawi declared public mental health services to be free of charge, as a strategy to reduce the burden of disease to the country. Yet despite the free health care services, the indigenous people of Malawi did not take advantage of these free mental health care services, as they regarded them to be culturally incongruent. Instead they used traditional healing systems for mental disorders and consulted the Western health systems only when the traditional systems had failed, the mental health condition had become worse and the mental health care user had become unmanageable. This study was then conducted to explore what the Malawians regarded as culturally sensitive public mental health services. Method: A qualitative phenomenological research approach was adopted to explore the views of the relatives of mental health care users about culturally sensitive public mental health care services. A purposeful sampling method was used to select information rich participants amongst the relatives of mental health care users of indigenous Malawian origin. An unstructured interview guide was used to gather data through face to face interviews. Saturation of data was reached after interviewing fifteen (15) relatives. The verbatim transcribed data from the participants were content analyzed to identify the themes, categories and subcategories. Themes that emerged were: community beliefs; perceived causes, delayed decision making and health system factors. viii Findings: The community beliefs about the management of mental disorders were on traditional and religious health systems. The traditional healers were consulted in cases where mental illness was believed to be caused by witchcraft and spiritual healers were consulted where mental illness was believed to be caused by ancestral wrath. Even such consultations were delayed as the decisions on the type of healer to be used to manage the mental health care user, had to come from the extended family members. These processes took place during the acute phase of the mental illness and thus explain the delays in consulting with the Western mental health care systems. Such delays had a potential to contribute to the chronicity and the related complications of the illness. The Western health care services were only consulted when the indigenous healing systems were unsuccessful. Yet even the western healing systems were not the best option due to the negative and disrespectful attitudes of health care professionals, the impersonal nature of services, the use of foreign language and delays in service delivery. The recommendations were that the results of this study should be used as guidelines to develop strategies for culturally congruent mental health care services to the indigenous Malawians as the development of the strategies was beyond the scope of this study. The focus of the guidelines to ensure the development of evidence-based nursing practices in rendering culturally congruent mental health services to the indigenous Malawians. Firstly, there should be an integration of both the Western and the traditional healing systems to ensure a holistic patient centered approach to the care of the indigenous people of Malawi; secondly to use the nursing process phases, starting with the assessment, the formulation of the nursing diagnosis, the expected outcomes, the development and implementation of the nursing interventions and the discharge ix plans to incorporate the belief systems of the indigenous Malawians as identified in this study.

- Description: The purpose of this study was to explore and describe the experiences of nursing students learning in a tertiary institution in East London in the Province of the Eastern Cape. Reviewed literature has revealed that the transition from high school to university is a major concern globally and that students start tertiary education with a number of pre-existing problems which influence their experience of learning and their academic performance. A qualitative, contextual approach and phenomenology design was seen as most appropriate to guide this research process in this study. Purposive, non-probability sampling was used to select the 12 participants. The participants included nursing students from the University of Fort Hare in East London in the Eastern Cape Province who are enrolled in the course leading to registration as a Nurse (General, Psychiatry and Community) and Midwifery. A pilot study was conducted at the University of Fort Hare involving respondents with similar characteristics to the study population.

- Description: This is a qualitative study which seeks to understand how Somali shop owners run successful businesses in the township of Soweto in South Africa. This research report has three sections, namely (1) the academic paper which comprises a shortened literature review, the research method, findings, and the discussion; (2) an extended literature review and (3) the research methodology. It is important to mention that these three sections are related and not necessarily stand-alone sections. Despite the hostilities faced by the Somali shop owners from the host communities in South Africa, it is notable that they are successful, small-sized entrepreneurs in most townships of South Africa (SA). Previous research on Somalis has predominantly focused on their assimilation into the societies in their host countries, and on how they are led into self-employment because of the unfavourable labour markets in the host country. In this vein, there is a need to understand how they run successful businesses in the townships of SA. This study seeks to answer the following research question: How Do Somali Shop Owners Succeed in Running Businesses in Soweto, South Africa (SA)? In pursuit of answers to the above research question, this study was confined to three locations in Soweto, namely Orlando West, Chiawelo and Rockville which have a relatively high number of Somali entrepreneurs who have been in operation for longer than three years. This qualitative study explored the multiple perspectives of reality of Somali shop owners. Purposively, 14 Somali shop owners were identified initially using purposive sampling. Subsequently, theoretical sampling was used to identify Somali shop owners who were interviewed regarding how they successfully run their businesses in the locations of Orlando West, Chiawelo and Rockville in the township of Soweto. A total of eighteen semi-structured, in-depth and face-to-face interviews were conducted with these shop owners as a means of gathering data to the point of saturating their perspectives. Data collection ceased when new perspectives were no longer evident as interviewees were being repetitive. Open-coding and constant comparison was used to analyse the data. The findings of the study show that ethnicity plays a predominant role in the success of the Somali shop owners. The intra-ethnic networks and trust-based support systems are pivotal to how Somali shop owners run successful businesses in Soweto. The key findings manifested showed that various forms of support came from Somali communities, family and fellow countrymen which were also central to their success. Another key finding showed that Somali shop owners run their businesses by complementing, rather than predominantly competing with the other local businesses, which ultimately differentiates them in this way. The study also revealed that responsiveness to local customer needs by enhancing the value of their business to the locality is also characteristic of how Somali shop owners build customer loyalty. This study contributes to our understanding of how Somali entrepreneurs conduct successful businesses in a hostile host country. The findings have implications for business development training and programmes which support immigrant entrepreneurs. The findings may also be extended to inform how business development programmes would be designed to equally support local entrepreneurs.

- Description: Social entrepreneurs seek to create social value in various ways in the community. Notably, they encounter not only enabling factors but also face and attempt to deal with a variety of challenges in their endeavor to start and run social ventures. This academic paper adopts a single case study approach with the aims to explore challenges and attempts to deal with them, as well as enablers, in how Dr Govender sought to create social value within the community of Gelvandale in Port Elizabeth in South Africa. Famhealth Medipark was chosen because it is unique and has been considered as an example of successful social entrepreneurship in Port Elizabeth. In the light of this, there has not been any previous study particularly focusing on its challenges and enablers in adding social value in the community through a multi-disciplinary venture. This research is valuable as it builds our understanding of how social entrepreneurs create social value. This qualitative study uses a single case study to focus on incidents of challenges and enabling factors as experienced, recollected and expressed by Dr Govender as a social entrepreneur. A variety of data, such as interview data collected through sampling incidents in nine in-depth initial and follow-up interviews, documents, audio documentaries and emails, were used. Open coding and constant comparison was used to analyze data and induce themes. Findings depict that Dr Govender as a social entrepreneur was propelled by four enablers: (1) strong enthusiasm to create positive change in others within a community, (2) network to resources, (3) a nurturing world view, and (4) consistent self-sacrifice. Dr Govender also revealed that he faced four types of challenges in setting up and operating Famhealth Medipark (FHM) as a vehicle with the sole purpose of creating and adding social value to the community of Gelvandale. Predominantly, (1) limitation of finance, (2) overwhelming effect of multiple roles, (3) negative effects of the non-accredited status of the care-giver training programme, and (4) the predominance of a destructive mindset entrenched within the Gelvandale community were key challenges he faced and attempted to deal with in setting up and operating a social venture to ultimately create social value. Although other types of data have been used, the predominant reliance on primary data collected through in-depth interviews is one of the major limitations of this qualitative study. However, this qualitative and exploratory study provides insights into our understanding of not only challenges encountered by social entrepreneurs but also the various drivers that sustain their social mission. Recommendations were then made, based on the findings from the research conducted.

- Description: Stories are a vehicle through which experiences and events are communicated amongst people. Stories have the potential to influence people’s understandings and beliefs, and essentially, promote a societal and cultural change. Grounded in literature pointing to the value of narrative in supporting learning and the need to explore new modes of communicating science, this study explores the potential of narrative in science education. The aim was to explore the use of a Story-Based Learning Design in a Grade 4 Science and Technology classroom. Using a qualitative case study research design the researcher took on the role of participant-observer. Data were collected through observations, learner verbal and written descriptions of a final product and teacher reflective interviews. The findings of this study illustrate the value of stories, as learning tools, in science education. In this regard pertinent conclusions were derived, namely, that stories attract learners and have the potential to be used as a vehicle for learning scientific concepts and the target vocabulary, that stories enable learners to make meaning of abstract concepts and relate it to their world and finally that the use of the imagination assists learners to visualise concepts making learning relevant.

- Description: Community participation has no single definition, but in simple terms it can be defined as a process of empowering the community or citizens by involving them in decision-making processes at all levels of government being from County, Payam and Bomas on all issues of concern that affect them politically, socially and economically. The main aim of this study is to investigate and identify the nature of and extent to which communities are given opportunities to participate in decision-making processes for effective service delivery in Lainya County. The main objectives of the study were to identify the obstacles to community participation in decision-making processes and how communities can be encouraged to participate effectively in decision-making, to meet their needs and interests. It further examines the extent to which communities play a role in promoting effective service delivery through participating in decision-making processes in Lainya County South Sudan. In this study, interviews, focus group discussions and observations were used as the main instruments for data collection on the issue of community participation as a tool for effective service delivery in Lainya County. These instruments are used to determine the extent to which communities are involved in decision-making processes to meet their needs and interests for effective service delivery. Data was collected from County officials comprising of Administrators, Chiefs, Women Associations Youth Associations and opinion leaders using both structured and unstructured interviews, focus group discussions and observations. Emerging from the study is that community participation is an integral part of the County developmental planning process. The study findings suggest that, public meetings, hearings, community workshops and seminars were the main mechanisms for community participation being used by the administrators. The study therefore, recommended among other things that; community participation be encouraged to promote community involvement in decision-making processes for effective service delivery. It also recommended that community participation and involvement be encouraged to initiate community development as it enhances program sustainability and ownership. The study further recommended that the top-down approach to decision making be replaced by bottom-up approaches, which emphasizes seeking communities’ ideas first before any developmental plans take place or are implemented. This study will significantly contribute to effective service delivery in Lainya County in the Republic of South Sudan.

- Description: E-governance is a comprehensive and well-thought out notion as it brings forth a change in the way governments communicate to citizens and to each other. Since the RSA government relies on regular consultations with the citizens in order to improve service delivery, e-governance approaches inspires citizens to be active agent of local democracy by means of providing information and participation on issues that matters the most to the society. The effectiveness of e-governance takes into account four systemic intentions which are as follows: Increased government accountability; Increased government transparency; Increased government efficiency and; Increased citizen’s trust In order for the RSA government, more particularly at the local level, to ensure quality of life to the citizens, the modernisation of government services and operations is very important. E-governance can now be considered as a source or tool for sharing ideas and initiatives that deliver a mutual enrichment. In other words, the citizens are the determining factor and actors for the rules and the role of the local bureaucrats as well as for the corresponding ICT tools persist to be developed. This treatise undertakes a strategic view and an evaluation of e- governance in local municipalities as the means of improving and transforming the delivery of services and access to information for citizens. Consequently this paper affords an exploratory analysis between e-governance and the six core elements of technology (i.e. e-strategy, e-skills development, e-services, IT governance and ICT infrastructure and e-leadership) believed to contribute positively in the effectiveness of e-governance. Finally, recommendations are made as a result of analysing the literature study and empirical study to ensure the implementation of the key initiatives of e-governance that can add value to the Nelson Mandela Bay Municipality (NMBM).
