- Description: The aim of the study is to investigate effective strategies and processes for public participation in the IDP process in the Buffalo City Metropolitan Municipality. A qualitative study was undertaken and literature review on public participation in terms of the Integrated Development Planning was conducted. Relevant secondary data was sourced and structured interviews were conducted with three (3) ward councillors in the Buffalo City Metropolitan Municipal. Focus group interviews were also conducted with ward committee members from three (3) wards in the Buffalo City Metropolitan Municipality. The findings of this research indicate that ward councilors have limited information on administrative processes. This could lead to ward councillors not be able to provide feedback on various service delivery issues and the progress of the municipal projects. Also ward councillors may not be able to influence public participation if they do not understand their role in administrative processes such as monitoring implementation of council decisions and policies. Ward councillors have no influence on the Integrated Development Planning especially the cost and budget estimates for municipal projects which are intended to benefit the members of the community. On the basis of the key findings, recommendations were made that ward committees should be empowered to deal with the complex developments in the Integrated Development Planning process and ward councillors should play a leading role in the Integrated Development Planning process.

- Description: The learning and analysis of algorithms and algorithm concepts are challenging to students due to the abstract and conceptual nature of algorithms. Algorithm animation is a form of technological support tool which encourages algorithm comprehension by visualising algorithms in execution. Algorithm animation can potentially be utilised to support students while learning algorithms. Despite widespread acknowledgement for the usefulness of algorithm animation in algorithm courses at tertiary institutions, no recognised framework exists upon which algorithm animation systems can be effectively modelled. This dissertation consequently focuses on the design of an extensible algorithm animation framework to support the generation of interactive algorithm animations. A literature and extant system review forms the basis for the framework design process. The result of the review is a list of requirements for a pedagogically effective algorithm animation system. The proposed framework supports the pedagogic requirements by utilising an independent layer structure to support the generation and display of algorithm animations. The effectiveness of the framework is evaluated through the implementation of a prototype algorithm animation system using sorting algorithms as a case study. This dissertation is successful in proposing a framework to support the development of algorithm animations. The prototype developed will enable the integration of algorithm animations into the Nelson Mandela Metropolitan University’s teaching model, thereby permitting the university to conduct future research relating to the usefulness of algorithm animation in algorithm courses.

- Description: The HIV and AIDS prevalence in Kenya is still high and remains a major health concern despite the Kenyan government’s initiatives to create awareness about the epidemic through inclusion of the HIV and AIDS programme in schools. This is because the provision of sexuality, HIV and AIDS education in schools is not effective. Teachers face various challenges in the effective delivery of the subject due to their discomfort related to these sensitive topics. Therefore, learners are left inadequately supported by the teachers. With an immense variety of conflicting information about sexuality availed to young people through the social media and also through their peers, young people are left at risk of exploring their sexualities with inadequate and wrong information, thus exposing them to HIV infections. Since schools have been identified as ideal sites for the effective delivery of sexuality, HIV and AIDS education, teachers are expected to teach the learners using a variety of pedagogical strategies in order to achieve efficacy in the delivery of this subject, hence the need to explore teaching styles that could provide a safe space for the effective delivery of sexuality, HIV and AIDS education. This study sought to explore teachers’ experiences of using participatory visual methods in teaching sexuality education within the HIV and AIDS education programme in selected Kenyan secondary schools, in order to understand how such methods could affect the teaching of Sexuality education. This study employed a phenomenological research design, interpretivist paradigm and a participatory methodology. Memory accounts, reflective journals and focus group discussions were used for data generation with nine secondary school teachers, from three purposively selected schools in Kenya. Vygotsky’s socio-cultural theory underpinned the study. The findings revealed that teachers are uncomfortable teaching sexuality education because of fear of leading learners astray, fear of victimization and sexualization, and fear of misleading and hurting learners because of lack of knowledge. This resulted in teachers feeling guilty due to ineffective delivery of Sexuality education. The findings also revealed that participatory visual methods were effective for use by the teachers and the learners in the classroom to navigate issues around sexuality, HIV and AIDS. This was because they are learner-centred, thus making learners producers of knowledge while at the same time encouraging optimism in teaching and learning. This study thus recommends pre-service teacher training on participatory methods of teaching. Educational institutions should also arrange for workshops to train in-service teachers on comprehensive sexuality, HIV and AIDS education and how to tackle it in their classrooms. Moreover, curriculum developers should make sexuality, HIV and AIDS education a compulsory subject to give it equal status with other examinable subjects, for it to be taken seriously. It is only through concerted efforts from everyone that Kenya can reach its target of Zero new HIV infections.

- Description: Abalone Haliotis midae farming in South Africa is highly intensive, employing pump-ashore, flow-through systems. Despite the known sensitivity of abalone to water quality, there is only a rudimentary understanding of water quality dynamics on South African abalone farms and its effects on abalone production. Furthermore, the potential for reusing the relatively dilute abalone farm effluent to culture other animal species has not been investigated. This study investigated the dynamics of water quality and growth on a South African abalone farm and assessed the suitability of the effluent for the culture of silver kob Argyrosomus inodorus and bloodworm Arenicola loveni loveni. Monitoring of water quality and abalone growth in abalone tanks revealed that oxygen concentrations decreased, while H⁺ ion and free-ammonia (NH₃) concentration increased in a gradient between the inflow and outflow. Abalone growth was positively correlated with oxygen concentration and negatively correlated with free-ammonia and H⁺ ion concentration. The oxygen (O) concentration of the farm influent was dependent upon the influents’ temperature (T) and was described by the relationship O (mg L⁻¹) = 11.244 – 0.208T (r²=0.74). Linear regression analysis of data collected from abalone farm tanks revealed that the concentration of total ammonia at the outflow of abalone tanks (μg TAN L⁻¹) was dependant upon temperature (°C), flow-rate (L s⁻¹ kg⁻¹ H. midae), abalone size (g) and length of time since the tank was last cleaned (d) (n = 125, r² = 0.80). The production of total ammonia (μg TAN s⁻¹ kg⁻¹) was related to temperature, abalone size and days that the tanks remained un-cleaned (n = 125; r² = 0.81). A diurnal cycle of respiration was evident in abalone tanks with higher oxygen consumption and H+ ion production at night. The oxygen concentration of farm effluent was related to temperature, farm biomass and flow rate by means of a linear regression equation (n = 40; r² = 0.69). The results demonstrated the importance of optimising the flow-rate per unit of biomass for various temperatures and sizes of abalone. As abalone size and temperature cannot be controlled under farm conditions, the flow-rate per unit of biomass which the abalone culture system receives will determine the quality of the culture water. The specific growth rate (0.48 ± 0.01 % BW d⁻¹), mortality (1.8 ± 0.5 %), feed conversion ratio (3.0 ± 0.2) and protein efficiency ratio (1.0 ± 0.1) of silver kob kept in either abalone farm effluent or control seawater for 120 days did not differ significantly (t-test, P>0.05). A 90 day growth trial indicated that abalone farm effluent is a suitable culture medium for bloodworm. Bloodworm supplied with control seawater lost weight at 0.19 ± 0.04 % BW d-1, while those given abalone effluent grew at 0.39 ± 0.07 % BW d⁻¹. Mortality was 6 ± 3 % in effluent and 11 ± 8 % in seawater. The bloodworm were efficient at processing solid waste. Abalone farm effluent initially contained 7.7 ± 13 mg L⁻¹ more suspended solids than control seawater, which contained 3.5 ± 0.5 mg L⁻¹, but after passing through bloodworm systems the concentration in abalone effluent was reduced to only 1.4 ± 3.5 mg L⁻¹ above that in control seawater. Therefore, abalone farm effluent could be reused as a culture medium for both silver kob and bloodworm. Future work is needed to investigate aspects of the feasibility of such systems such as growth rates at different sizes and stocking densities.

- Description: Xenophobia became known as manifest of relations and perceptions of an "in–group" towards an "out-group", including a fear of losing identity, suspicion of its activities, aggressions, and desire to eliminate its presence to secure a presumed purity. This study aims to address the socio-economic impacts of xenophobia in South Africa. As a matter of fact, the 2008 xenophobia attacks amongst others were violent and acted as visible wake-up call to the country to focus attention on the reality of human migration. South African democratic constitution recognises immigration, and gives multiple reasons why nationals from other countries have to migrate to settle in South Africa. This study was grounded within the field of Development studies and undertook a case study of investigating the socio- economic impacts of xenophobia in Nelson Mandela Bay Metropole (NMBM) as a case study. The study employed the use of semi- structured interviews whereby a questionnaire was used to guide the researcher in the interview process. A total of 40 officials were interviewed, ranging from governmental department through to civil societies to private immigration consultants and immigrants in South Africa, in order to avoid the generation of biases. The data obtained from respondents were presented, analysed, and discussed. From the data collected, it was possible to single out the impacts of xenophobia in NMBM. Some of the consequences generated from the fact that the community need more awareness programs, the local and national government need to capacitate the citizens to create sustainable jobs and the DoHA‟s activities greatly relegate immigrants to the backyard. Based on the study findings, the main recommendations offered to NMBM was to create a forum to advice the DoHA to channel efforts into managing migration issues sustainably rather than "stopping" it. Furthermore to catalyse Civil Society and NGOs to initiate support mechanisms to hold government accountable. This will greatly provide a perfect platform for development.

- Description: This study examined job characteristics and organisational citizenship behaviour among employees in a previously disadvantaged South African University. A structured questionnaire was used to collect data from 149 randomly selected participants. A 5-point Likert scale job characteristics survey by Hackman and Oldham (1975) was used to measure job characteristics while, a 5-point Likert scale by Lee and Allen (2002) on organisational citizenship behaviour was used to measure employee’s organisational citizenship behaviour. Different statistical techniques such as Spearman rho correlation technique and Regression analysis were used to analyse data. The results showed that task significance, skills variety, autonomy and feedback are significantly positively related to organisational citizenship behaviour. There was a non-significant negative relationship between task identity and organisational citizenship behaviour. A combination of two or more job characteristics dimensions were found to report a higher proportion of variance in organisational citizenship behaviour than any one job characteristic separately. The study, thus, recommends that managers must design employees’ jobs or tasks that are more meaningful to stimulate the display of organisational citizenship behaviour. Initiatives that stimulate the use of a variety of skills, promotes feedback, promote task significance and autonomy were suggested as solutions to stimulate the display of OCB. The prevalence of such dimensions on one’s job increase motivation and satisfaction therefore contributing positively towards organisational citizenship behaviour.

- Description: This study was conducted to determine species composition and seasonal population dynamics of free-living and engorged cattle ticks in three agro-ecological zones (Bedford dry grassland, Kowie thicket and Bisho thornveld) of the Eastern Cape Province, South Africa. The occurrence of ticks on cattle was studied monthly from April 2016 and March 2017. Tick collections were performed on 360 selected cattle in each agro-ecological zones. During tick collections, 10 randomly selected cattle were sampled at each locality and more attention was given to African blue tick and the presence of Asian blue tick. A half body tick collection was performed from cattle and visible ticks were collected by means of fine-forceps after the animals had been restrained. Body regions that were examined includes the ear, head, neck, chest, abdomen, flank, front and hind leg and feet, tail, and peri-anal region. At each locality, six replicate drags of 100 m, approximately 50 m apart, were performed to collect ticks from vegetation. All ticks collected per cattle and from vegetation were stored in labelled sample tubes containing 70percent ethanol, subsequently counted and identified to genus and species level using a standard stereomicroscope. A total of 31425 ticks belonging to ten species were collected during the study. Rhipicephalus (Boophilus) decoloratus, was the most observed tick species (32.50percent), all other ticks like R. evertsi evertsi (18.84percent), R. appendiculatus (17.26percent), A. hebraeum (16.27percent), R. simus (7.69percent) were also commonly collected. Ixodes pilosus (3.84percent), H. rufipes (3.46percent), R. follis (0.08percent) together with Haemaphysalis silacea (0.02percent) were sporadic infestation. Haemaphysalis elliptica (0.04percent) was only found on the vegetation. No H. rufipes was collected in the thicket vegetation. Agro-ecological zones differ significantly (P<0.05) in tick species and distribution. Significantly more R. (B.) decoloratus were collected in thicket during summer compared to thornveld and dry grassland regions (P<0.05). Free-living ticks were widely distributed across different seasons but with of R. (B.) decoloratus larvae were significantly higher (P<0.05) in thornveld region during the spring season. In conclusion, agro-ecological differences and seasonal variations had an influence on ticks abundance and distribution. From this study, it is of interest to note the absence of R. (B.) microplus, whose trend to invade new areas previously colonised by R. (B.) decoloratus has been observed in Africa. In conclusion, agro-ecological differences and seasonal variations had an influence on ticks abundance and distribution. The aforementioned absence of R. (B.) microplus in this study highlights the importance of further research as this tick invades new areas previously colonised by R. (B.) decoloratus in the continent.

Rhipicephalus (Boophilus) decoloratus, was the most observed tick species (32.50percent), all other ticks like R. evertsi evertsi (18.84percent), R. appendiculatus (17.26percent), A. hebraeum (16.27percent), R. simus (7.69percent) were also commonly collected. Ixodes pilosus (3.84percent), H. rufipes (3.46percent), R. follis (0.08percent) together with Haemaphysalis silacea (0.02percent) were sporadic infestation. Haemaphysalis elliptica (0.04percent) was only found on the vegetation. No H. rufipes was collected in the thicket vegetation. Agro-ecological zones differ significantly (P<0.05) in tick species and distribution. Significantly more R. (B.) decoloratus were collected in thicket during summer compared to thornveld and dry grassland regions (P<0.05). Free-living ticks were widely distributed across different seasons but with of R. (B.) decoloratus larvae were significantly higher (P<0.05) in thornveld region during the spring season. In conclusion, agro-ecological differences and seasonal variations had an influence on ticks abundance and distribution. From this study, it is of interest to note the absence of R. (B.) microplus, whose trend to invade new areas previously colonised by R. (B.) decoloratus has been observed in Africa. In conclusion, agro-ecological differences and seasonal variations had an influence on ticks abundance and distribution. The aforementioned absence of R. (B.) microplus in this study highlights the importance of further research as this tick invades new areas previously colonised by R. (B.) decoloratus in the continent.

A literature review of the factors impacting on objectivity in news journalism

- Language: English
- Type: Thesis , Masters , MA
- Identifier: vital:8376 , http://hdl.handle.net/10948/872 , Journalism -- Objectivity
- Description: Objectivity has been the most debatable issue in the history of journalism and there are, therefore, many different ways of looking at it. Media academics such as Gans (1979) and Tuchman (2000) refer to objectivity as an examination of contents of collected news materials. Glasser (1992) points out that objectivity is a balance of beliefs restructured by a journalist and presented against independent thinking. It is difficult to test the objectivity of journalists because it is the credibility of facts gathered by a journalist that lies at the heart of objectivity. In Glasser’s opinion, the “notion” of objectivity is flawed against the newsman’s mandate of reporting responsibly. Objectivity is therefore professional principle through which journalists write news responsibly and present it to their audience as a final product (Glasser, 1992). This study will discuss objectivity also in reference to the problems that journalists face when they cover news stories. It may be that journalists may have problems searching for stories not because they do not embrace journalistic principles of fairness, clarity and objectivity, but because of the way in which facts are presented to them by news sources (Fred and Wellman, 2003). There have been some cases whereby media audiences have wrongly been made to think that journalists are biased in their coverage. 2 For example, the 2003 Iraq invasion by US-led forces, where correspondents were made to practice embedded journalism is a good example of how circumstances could force a journalist to succumb to soldiers’ demands of keeping their war causalities away from their cameras. It is worth noting, however, that being biased for a journalist in such a war situation could be circumstantial in the sense that an American journalist covering a story in Iraqi’s capital, Baghdad, would be regarded as a spy by Iraqi’s troops. Likewise, an Iraqi journalist chasing stories in the coalition force’s camps in Iraqi’s capital would be treated as a traitor by the Iraqi people (Fred and Wellman, 2003:21). There is no doubt that in the situations described above objectivity in journalism can be affected. It is against such background that this study will investigate the factors that affect objectivity in the print media. It is vitally important to bear in mind that bias should not be confused with editorial columns that express the opinion of publishers, or editors for that matter. The question of objectivity goes back to the gatekeepers, whereby the editors as gatekeepers decide what to publish and what news stories reporters should gather. So the question of objectivity in the news can be dealt with by the editors who decide which story should be run by their respective newspapers. According to Fred and Wellman (2003:32), editors and media owners are the decision makers in the field of journalism.

- Description: This study seeks to investigate the challenges faced by the recipients of the child support grant, with special reference to Morgan Bay, a rural area under the aegis of the Amathole District Municipality in East London. The child support grant is a strategy that was introduced to alleviate poverty in previously disadvantaged communities. The child support grant replaced the state maintenance grant. South Africa has high levels of unemployment; and this situation is considered to be a major contributing factor to poverty. After the apartheid era, the African National Congress (ANC) led government introduced a litany of redistributive policy frameworks aimed at reversing the imbalances of the past created by the apartheid government. The child support grant, which was established during the year 1998, is viewed as one of the strategies introduced by the South African government aimed at alleviating poverty caused by the lack of jobs. The aim of the study is to assess the implementation of the child support grant impact as a developmental strategy in rural communities, such as Morgan Bay. The study seeks to determine how the child support grant redistribution has affected rural communities. In other words, the research seeks to determine whether the child support grant redistribution has affected rural communities positively or negatively, and to ascertain whether it has mitigated the impact of socio-economic challenges in rural communities. The study also seeks to explore other strategies, which could be implemented to supplement the child support grant, and possibly decrease the level of dependence on the child support grant – by having a back-up strategy for alleviating poverty.

- Description: Malaria, a mosquito-borne infectious disease, caused by the protozoan Plasmodium genus, is the greatest health challenges worldwide. The plasmodial vitamin B1 biosynthetic enzyme PfThzK diverges significantly, both structurally and functionally from its counterpart in higher eukaryotes, thereby making it particularly attractive as a biomedical target. In the present study, PfThzK was recombinantly produced as 6×His fusion protein in E. coli BL21, purified using nickel affinity chromatography and size exclusion chromatography resulting in 1.03% yield and specific activity 0.28 U/mg. The enzyme was found to be a monomer with a molecular mass of 34 kDa. Characterization of the PfThzK showed an optimum temperature and pH of 37°C and 7.5 respectively, and it is relatively stable (t₁/₂=2.66 h). Ag nanoparticles were synthesized by NaBH₄/tannic acid, and characterized by UV-vis spectroscopy and transmission electron microscopy. The morphologies of these Ag nanoparticles (in terms of size) synthesized by tannic acid appeared to be more controlled with the size of 7.06±2.41 nm, compared with those synthesized by NaBH₄, with the sized of 12.9±4.21 nm. The purified PfThzK was challenged with Ag NPs synthesized by tannic acid, and the results suggested that they competitively inhibited PfThzK (89 %) at low concentrations (5-10 μM) with a Ki = 6.45 μM.

- Description: An investigation of ecosystem functioning of sandy beaches in the Nelson Mandela Bay Municipality (NMBM) was carried out with the aim of describing their type and pollution status. Water salinity, temperature, pH, beach slope, water inorganic nutrient concentrations, urea, and chlorophyll-a concentration as well as the composition of zooplankton, phytoplankton, meiofauna, benthic microalgae and bacteria were examined at thirteen beaches. The beaches were classified into three types: short beaches; long beaches with surf diatoms; and long beaches that import biomass (without surf diatoms). Of the thirteen beaches, five were non-polluted and eight polluted with polluting human activities in and around them. Most beaches were dominated by fine sand except for St. Georges Strand where the particles were medium to fine sand and Maitland’s River Beach, Bluewater Bay and Sardinia Bay that had coarse sand. Nutrient concentrations ranged from 1.98 ± 0.10 μM to 19.30 ± 3.02 μM nitrate; 4.88 ± 1.00 μM to 11.97 ± 1.00 μM ammonium; 0.67 ± 0.00 μM to 2.31 ±1.00 μM soluble reactive phosphorus; and 0.00 to 0.03 ± 0.00 μg l-1 urea-N. Chlorophyll-a concentrations ranged from 0.04 ± 0.02 to 1.57 ± 0.11 μg l-1. Chlorophyll-a concentrations were negatively correlated to ammonium for all beach types (short beaches: r = 0.94; long importing beaches: r = 0.95 and surf diatom beaches: 0.94) and to nitrate for short and long importing beaches (short: r = 0.97 and long importing: r = 0.85). By contrast, a positive correlation was found between observed between chlorophyll-a concentrations and urea for surf diatom beaches (r = 0.93) and for long importing beaches (r = 0.73). Chlorophyll-a concentrations were negatively correlated to short beaches (r = 0.99) and long importing beaches (r = 0.76). The E. coli and total coliforms in all the sampled beaches were within the recommended South African water quality guidelines for contact recreation as specified by DWAF (1995) except at New Brighton Beach (2 419 total coliforms/100 ml and 1 853 E. coli cells/100 ml) and St. Georges Strand (274 total coliforms/100 ml). Diatoms dominated the phytoplankton and benthic microflora; calanoid copepods dominated the zooplankton and deposit-feeding nematodes dominated the meiofauna in all the beaches with no changes found at polluted beaches.

- Description: This research study aims to identity the shifts in form and function of English writing in Computer Mediated Communication (CMC) and determine whether writing changed through CMC. It critically evaluates English writing in CMC in South Africa, and includes a case study of both synchronous and asynchronous forms of CMC. Chapter 1, outlines the problem concerning the changes of writing in both form and function in the present age of CMC. This chapter, also gives a detailed description and outlines the methodology of this study. Chapter 2, centres on the historical and theoretical aspects of writing using the work done by scholars such as McLuhan, Shlain and Baron. The literature is divided into two subsections. The research and theories highlights the importance and complexity of writing in human history. It also gives insight into understanding the impacts of different mediums on writing. This chapter similarly depicts an understanding in the use of writing to represent language, and in particular, how speech and writing divvied up communication functions in literature societies. Chapter 3, gives a detailed theoretical and critical outline of writing in the present age of CMC. Based on the nature of the computer medium, writing in CMC often has its own characteristics which can serve both developmental and social purposes. The aim of this chapter is to grasp an appropriate analogy through which to capture the changes the computer technology would engender in writing communication, and re-examine the relationship between writing and speech in CMC. Chapter 4, comprises of an empirical research study done in South African on-line discourse, focusing on the changes of writing in CMC. The hypothesis of this case study is that writing in CMC differentiates the conventional writing in a variety of ways. Therefore, the study looks at the particular writing style in CMC and determines whether computer-mediated writing is gradually becoming a mirror of speech. This chapter explains methodology and the process of data coding in this case study. It also includes a summary of the survey results, as well as a discussion of the findings from this case study. Chapter 5, includes a conclusion of this study and suggestions for further research. It is the hope of the researcher that this study will provoke questions and thoughts for further inquiries.

At the mean time, universities around the world encourage their international offices to increase the foreign student enrollments. This research investigates the factors influencing international students’ choice of enrolling at Higher Educational Institutions (HEI) via the internet: international students’ Internet use to facilitate information search and decision making. This survey of international students from Nelson Mandela Metropolitan University (NMMU) explored the Internet’s role in marketing international education. Based on this exploratory research, NMMU educational institutions gain insights of online customer service for successfully recruiting students. The results show that prospective overseas students do indeed use the internet. Overall evaluation of the factors influencing the use of the internet for enrolling at HEIs was determined by four factors: namely, perceived usefulness, consumer involvement, perceived ease of use and opinion leadership.

This rural community was established as a resettlement center during pre-1994 South African government forced removals (Hallett, 1994). Glenmore is economically and socially impoverished as there are few businesses, little economic activity and minimal social tradition in the settlement (Murray, 1989). This village is characterised by an out migration of people of an economically active age, high unemployment amongst residents, dysfunctional families due to parents living elsewhere in order to earn a living, and a youthful population desperate to obtain skills and experiences that will benefit them when they leave Glenmore in the future.

- Description: South African vehicle manufacturers are under immense competition from vehicle manufactures from India and China. The global financial crises also put these organisations under intense pressure and this resulted in these organisations having to start seeing the need to focus on issues that affect customer retention. The way that business is done in the 21st Century is forcing organisations to implement strategies that are geared towards increasing customer retention and growing the business. Organisations need to build relationships with their customers with the hope that these customers will in turn extend their stay with the organisation when an opportunity to replace their vehicles arises or keep on servicing with them. In order to establish a good relationship with customers, organisations need to understand customer expectations by being customer orientated and by providing customers with value. The primary objective of this study is to improve customer retention for a selected vehicle manufacturer after the warranty and service plans have expired, by investigating the relationship between customer service quality, customer loyalty, and customer retention. The results obtained from the 64 respondents who participated in the survey revealed that although all the above-mentioned variables play a role in increasing customer retention, customer service quality exerts the most influence.

- Description: South African vehicle manufacturers are under immense competition from vehicle manufactures from India and China. The global financial crises also put these organisations under intense pressure and this resulted in these organisations having to start seeing the need to focus on issues that affect customer retention. The way that business is done in the 21st Century is forcing organisations to implement strategies that are geared towards increasing customer retention and growing the business. Organisations need to build relationships with their customers with the hope that these customers will in turn extend their stay with the organisation when an opportunity to replace their vehicles arises or keep on servicing with them. In order to establish a good relationship with customers, organisations need to understand customer expectations by being customer orientated and by providing customers with value. The primary objective of this study is to improve customer retention for a selected vehicle manufacturer after the warranty and service plans have expired, by investigating the relationship between customer service quality, customer loyalty, and customer retention. The results obtained from the 64 respondents who participated in the survey revealed that although all the above-mentioned variables play a role in increasing customer retention, customer service quality exerts the most influence. The study also highlights areas that should be improved, as well as recommendations on how to improve them. Recommendations for future research are also provided.

- Description: Recently, the automation of service integration has provided a significant advantage in delivering services to novice users. This art of integrating various services is known as Service Composition and its main purpose is to simplify the development process for web applications and facilitates reuse of services. It is one of the paradigms that enables services to end-users (i.e.service provisioning) through the outsourcing of web contents and it requires users to share and reuse services in more collaborative ways. Most service composers are effective at enabling integration of web contents, but they do not enable universal access across different groups of users. This is because, the currently existing content aggregators require complex interactions in order to create web applications (e.g., Web Service Business Process Execution Language (WS-BPEL)) as a result not all users are able to use such web tools. This trend demands changes in the web tools that end-users use to gain and share information, hence this research uses Mashups as a service composition technique to allow novice users to integrate publicly available Service Oriented Architecture (SOA) services, where there is a minimal active web application development. Mashups being the platforms that integrate disparate web Application Programming Interfaces (APIs) to create user defined web applications; presents a great opportunity for service provisioning. However, their usability for novice users remains invalidated since Mashup tools are not easy to use they require basic programming skills which makes the process of designing and creating Mashups difficult. This is because Mashup tools access heterogeneous web contents using public web APIs and the process of integrating them become complex since web APIs are tailored by different vendors. Moreover, the design of Mashup editors is unnecessary complex; as a result, users do not know where to start when creating Mashups. This research address the gap between Mashup tools and usability by the designing and implementing a semantically enriched Mashup tool to discover, annotate and compose APIs to improve the utilization of SOA services by novice users. The researchers conducted an analysis of the already existing Mashup tools to identify challenges and weaknesses experienced by novice Mashup users. The findings from the requirement analysis formulated the system usability requirements that informed the design and implementation of the proposed Mashup tool. The proposed architecture addressed three layers: composition, annotation and discovery. The researchers developed a simple Mashup tool referred to as soa-Services Provisioner (SerPro) that allowed novice users to create web application flexibly. Its usability and effectiveness was validated. The proposed Mashup tool enhanced the usability of SOA services, since data analysis and results showed that it was usable to novice users by scoring a System Usability Scale (SUS) score of 72.08. Furthermore, this research discusses the research limitations and future work for further improvements.

- Description: In this study, a series of Ru(II) phenyl-3-indenylidene complexes with general formula of [RuCl2(NHC)(Ind)(L)] (where L= triphenylphosphine, pyridine and NHC = five different types of N-heterocyclic carbene ligands), have been synthesized and characterized using FT-IR, UV-Vis, elementally analysis and melting/decomposition point. The N,N’-diarylimidazolinium chlorides have been used as N-heterocyclic carbene precursors and were synthesized from their corresponding N,N’-diarylformamidines and further characterized using 1H-NMR, 13C-NMR, FTIR and melting point determination. The infrared spectra of the N,N’-diarylimidazolinium chlorides show a quaternary nature (R2N=C+) with broad vibration band in region 3300-3400 cm-1. The disappearance of this vibration band in the infrared spectra of the ruthenium(II) complexes was used to confirm the coordination of the ligand to the ruthenium ions. The percentage analysis of carbon, hydrogen and nitrogen obtained corresponded with the calculated percentages of these atoms in the complexes with the slight difference of less than 1%. The electronic spectra of the complexes show three distinct absorption bands. The two bands are due to intraligand charge transfers transition assigned to π→π*, n→π* and third band is due to d-d transition, signifying the presence of the metal ion. The synthesized Ru(II) complexes did not show any of melting, however a change in colour was observed signifying the decomposition of the complexes.

- Description: A great deal of taxpayers’ money has gone to a lot of SMME development initiatives. Despite this effort over the past 17 years, South Africa (SA) lags behind other developing countries, in promoting the growth and sustainability of SMMEs. The impact and achievements of government initiatives have fallen disappointingly short of aspiration (Business Development in South Africa. 2009. Occasional paper). Aims and Objectives: •To evaluate and reflect on the OR Tambo District Municipality SMME funding model and establish whether it has made the desired impact. •Determine if funds that have been channelled by the SA government to SMMEs for business expansion, start-ups, grants, and special industry development have yielded quantifiable results and •Assess the private funding institutions in assisting destitute entrepreneurs in the OR Tambo District municipality. Research methodology: The study was conducted using qualitative research and a questionnaire was used as a data collection tool. The researcher was able to get valuable information on stakeholders in the SMME sector. The stakeholders (SMMEs and funders), formed the core research sample. Results: findings suggest that the OR Tambo Municipality has a funding gap and the current funding model both from public and private funders is not effective in developing SMMEs in the municipality. The overwhelming majority of SMMEs agreed that there is a funding gap between funders and enterprises that seek funding in the ORTDM. “Financing gap” terminology, Underhill Corporate Solutions (UCS) (2011:52) defines it as, ‘a sizeable share of economically significant SMEs cannot obtain financing from banks, capital markets or other finance suppliers.’ About 90 percent of the interviewed SMMEs agreed that there is huge funding gap and 10 percent disputed this and said that there is no funding gap; rather, it’s a funding mismatch between the funders and SMMEs which needs to be tackled by all SMMEs stakeholders. The funding model needs to be revamped so it can also be accessible to start-ups, the unemployed, people with less business management experience and limited skills, and to all sectors of the economy. Various recommendations and suggestions for further research are made based on the research findings. Conclusion: The study has shown that the current SMME funding model is not effective and does not assist in developing SMMEs in ORTDM. The research findings depict the funding plight of SMMEs in South Africa; the SMME plight in ORTDM is more real than imaginary. 70 percent of SMMEs expressed less confidence in government SMMEs agencies in terms of assistance. The bigger portion of SMMEs felt that the funds channelled to government agencies were not providing significant assistance in developing SMMEs in ORTDM. Recommendations: The conclusive response from the sample, reflect structural challenges in the current funding model. About 70 percent of funding institution`s officials said “yes”, the low yield on SMME growth is a matter of funding. The funds which were meant to fund SMMEs for one reason or the other do not reach SMMEs which are looking for funding. Hence the funds channelled in the sector in the last 17 years have not yielded the desired results. 40 percent interviewed government officials conceded that there is serious political meddling in funding SMMEs in the whole province and ORTDM could not be an exception to this rule. 80 percent of interviewed SMMEs in ORTDM said funding was their main problem, and the other 20 percent indicated that their problem was not a matter of funding. The public and the private sector must revise the current funding model or devise another funding model that will: •bridge the existing current funding gap, •distribute the SMME allocated budget and achieve maximum efficiency in budget allocation.

- Description: Moringa oleifera Lam. is native to the Indian ecotype, which has become naturalized in many tropic and subtropic regions worldwide, thus a great variation in the bioactive compounds of the plant is recorded. The introduction of Moringa oleifera to South Africa occurred in the turn of the twentieth century with the aim of combating malnourishment, aiding health and fostering economic development. Therefore, this study was conducted with the aim of evaluating and authenticating the nutritional parameters, essential oil and bioactive components found in the various solvent extracts of Moringa oleifera leaves cultivated in the South African ecotype. It also elucidated some of the plants medicinal properties by investigating the antioxidant and antibacterial properties of the plant. The essential oil of the leaves was extracted using two methods (solvent free microwave extraction and hydrodistillation) and analysed using Gas Chromotography/Mass Spectrometer. The safety profile of the leaves was investigated using brine shrimp model. The results from the study revealed that Moringa oleifera leaves cultivated in South Africa were rich in crude protein levels (28.72%) and carbohydrate (28.84%). Among the minerals tested for, the leaves contained high content of calcium (1603.33 mg/100 g), potassium (1690 mg/100 g), zinc (13.03 mg/100 g) and iron (21.13 mg/100 g). The vitamin E content had the highest concentration (89.43 mg/100 g) among the vitamins evaluated. The leaves of Moringa oleifera had low quantities of antinutrients in relation to minerals, thus ensuring nutrients availability. This study identified 15 fatty acids in the dried leaves of Moringa. The highest fatty acid detected were polyunsaturated fatty acids, linoleic acid (56.36) and alpha-linolenic acid (687.58), 7 of the fatty acids were saturated fatty acids, though relatively low besides stearic acid. 15 amino acids were present, 7 of which were essential amino acids, namely; threonine, tyrosine, methionine, valine, phenylalanine, isoleucine and leucine. vi Among the phytochemicals evaluated, the aqueous extract gave the highest total phenolic content (21.01 ± 2.315 mg GAE/g), the acetone extract gave the highest proanthocyanidin (15.33 3.5 mg CE/g) and flavonoid contents (25.04±3.28 mg QE/g), while saponin and alkaloid contents were 27.73 ± 9.97% and 7.32 ± 2.73 % respectively. All the extracts exhibited high radical scavenging power against the 2,2- diphenyl-1-picrylhydrazyl radical with an IC50 less than 0.025 mg/mL. Aqueous extract gave the highest capacity based on ABTS and TAC assays with IC50 of 0.074 mg/ mL and 0.055 mg/mL respectively. Ethanol extract exhibited the least antioxidant capacity among the extracts, as well as the least antimicrobial activity on both Gram −ve and Gram +ve bacteria with all its minimum inhibitory concentration values greater than 5 mg/mL. The acetone extract exhibited the strongest antimicrobial activity among the extracts. A total of 8 and 24 chemical compounds were found from the solvent-free microwave extracted and hydrodistilled oils, respectively. The major components found from hydrodistillation were 2-Hexanal (16.37%), Nonanal (6.09%), 5 9-undecadien-2-one 6, 10 dimethyl- (e) - (8.01%), trans-beta-Ionone (8.02%) and octadecane (9.67%). For the solvent free microwave extracted oil, Benzene acetaldehyde (5.68%), Octadecane, Pentacosane and Eicosane which were 11.03%, were the major components. Toxicity evaluation revealed that mortality was time dependent. As the exposure period increased, mortality kept increasing. The hatching success of the cysts in acetone, aqueous and ethanol extracts were 35.7, 33.6 and 35.2% respectively. Acetone extract showed the most prominent hatching success. Hatchability and lethality were in a concentration dependent fashion. Among the extracts, acetone extract exhibited the highest lethality (12.3%) to the nauplii, followed by ethanol (10.9%), then aqueous (5.6%) extracts. All the results obtained from this study suggest that Moringa has the potential of eradicating malnutrition and aid health. It contains the necessary nutritional and bioactive compounds and the leaves proved not to be toxic at the levels (0.0625 – 1 mg/mL) tested.

- Description: The research seeks to assess the efficacy of the oversight role of portfolio committees of Parliament with specific reference to the Portfolio Committee on Public Works between 2010 and 2015. The Portfolio Committee on Public Works has an overarching oversight role over all infrastructural and maintenance services rendered by the Department of Public Works. The Department of Public Works fulfils a pivotal function in the infrastructural and maintenance service rendition to all departments in the executive. This function overlaps on provincial and local government spheres. The researcher dwells much on the capacity and competency of members of portfolio committees and support staff in their use of oversight tools, inclusive of the Theory of Change, Monitoring and Evaluation, Budget Cycle Model, Public Sector Oversight Model and Logical Framework when conducting oversight within a financial year. The critical point that was noted was the inadequate time allocated by the Joint Programme Committee for committee oversight and the inadequate capacity of members and support to apply the instruments designed for effective and efficient oversight. The dearth of application of appropriate instruments for oversight is exacerbated by the proliferation of executive government departments, which stretches the work of the Portfolio Committee of Public Works without stretching the resources. The research methodology used included data collection using questionnaires and interviews as instruments for assessment. Questionnaires were distributed to all Whips of all parties in Parliament. A sample size was measured from the total number of members of Parliament less ministers and their deputies and officials. The sample was fifty members. After analysis of the data, it transpired that the responses on the questionnaires gave a convincing result confirming some assumptions that triggered the research. The researcher arrived at conclusions and thereafter suggested recommendations. The research reflected on weaknesses and achievements of the portfolio committees in their oversight role and stressed the importance of the application and use of oversight-related tools and models in order to achieve best practices for developmental results.
