  • Description: Escherichia coli (E. coli) is a widespread species that includes a broad variety of strains, ranging from highly pathogenic strains causing worldwide outbreaks of severe disease to virulent isolates which are part of the normal intestinal flora or which are well characterized and safe laboratory strains. The pathogenicity of a given E. coli strain is mainly determined by specific virulence factors which include adhesins, invasins, toxins and capsule. The aim of this study was to evaluate the prevalence and antibiogram profiles of E. coli pathotypes previously isolated from Kat River and Fort Beaufort abstraction water. A total of 171 E. coli isolates showed at least one pathogenic determinant among the isolated 278 E. coli. The other 107 isolates were negative for the tested virulence genes. All 278 presumptive isolates tested positive for the UidA gene, and were therefore classified as non-categorized pathogenic E. coli. The 171 pathogenic isolates had at least one characteristic gene of pathogenic E. coli and were identified and classified as enteropathogenic E. coli (6%), enterotoxigenicE. coli (131), uropathogenic E. coli (6), neonatal meningitis E. coli (14), diffusely adherent E. coli (1) and enterohaemrrhagic E. coli (1). Interestingly, no virulence genes were detected for the enteroinvasive E. coli and the enteroaggregative E. coli. The antibiotic resistance profiles for all isolates that were identified as E. coli showed 100% resistance to penicillin G, 98% resistance to ampicillin, 38% resistance to trimethoprim-sulphamethoxazole and 8% resistance to streptomycin. Multiple antibacterial resistance (MAR) was also observed, where 44% of the isolates were resistant to three antibiotics and 8% resistant to four antibiotics. The results of this study showed the Kat River and Fort Beaufort abstraction water are reservoirs of pathogenic strains of E. coli which harbour antibiotic resistance determinants that can cause serious health risks to the people in the surrounding communities.

  • Description: The objectives of this research project were to identify and compare factors that influence the purchasing decisions of Multifibres’ customers active in each channel. Multifibres manufactures and distributes industrial cleaning rags to three channels or client categories, these being industrial resellers, industrial end-users and the walk-in customers. An extensive literature review revealed that purchasing decisions are influenced by, amongst other factors, the buyer’s role, the internal cognitive processes of the buyer, as well as factors present in the buyer’s business and external environment. An empirical study was conducted utilising in-depth interviews. The most prevalent, emergent themes that buyers attached the greatest weight to when purchasing cleaning rags were: price; quality; service; relationships; and, convenience. These factors were probed, analysed and compared, based on each buyer category’s unique set of characteristics. When motivating their purchasing preferences, resellers emphasised the importance of the business relationship and trust as being paramount, while end-users viewed price and service as the most important factors. Walk-in customers valued the combination of price and convenience as the most important reasons influencing their purchasing decisions.

  • Description: Collective bargaining is the process whereby employees act as a collective unit whilst negotiating terms and conditions of employment with employers. The collective unit typically takes the form of a trade union, mandated by its members to negotiate on their behalf. By negotiating collectively the inherent imbalance of power between employer and individual employee is seen to be neutralised. The process of collective bargaining enjoys legal status in South Africa and around the world. The Industrial Conciliation Act of 1924 institutionalised collective bargaining for the first time in the form of the Industrial-Council system. This sectoral bargaining system stood firm throughout the pre-democracy period but initially excluded non-white employees. Industrial unrest in the 1970s was the catalyst for the Wiehan commission which ultimately brought all employees into the fold. By the dawn of democracy in South Africa the bargaining system enjoyed wide-spread support and legitimacy. This was particularly so amongst the COSATU-led labour movement which enjoyed a position of political strength. This support and strength were reflected in the contents of both the Labour Relations Act and the Constitution which enshrined the constitutional right to engage in collective bargaining. Possibly the most debated aspect of the Council system has been the question of extending agreements to non-parties. Those in favour argue that the Council system cannot function in the absence of extensions. This is so because what would then effectively be a voluntary system would not attract sufficient volunteers. Those against argue that extensions act as a barrier to economic activity, particularly for small and new businesses. Legislation has, since 1924, facilitated the extension of agreements as long as certain criteria are met. Section 32 of the Labour Relations Act is the current extension vehicle. The extension criteria have vacillated over time and especially so in recent history with section 32 being subject to change in every post-democracy amendment to the Act. Possibly the most serious challenge to the extension status quo has come in the form of a constitutional challenge by the Free-Market Foundation. The Foundation advances old economic arguments but links these to an alleged impingement of constitutional rights. The challenge comes at a time when the country is experiencing the most significant socio-political turbulence since democracy. This includes the most enduring strike in our history, a landmark-employer lock-out and a parliamentary facelift. The Metal and Engineering Industries Bargaining Council oversees the biggest manufacturing sector in the South African economy. This status prompted the Council to submit its own responding papers in the Free-Market case. Particularly fascinating is that an employer party to the Council not only supports the Foundation case but has also lodged its own proceedings against the extension of the 2014 Engineering agreement. Both these cases are still pending and the outcomes have the potential to transform the political and economic landscape of our country.

  • Description: The purpose of this project was the specification, design and implementation of a prototype 2-D MPEG-4 authoring tool. A literature study was conducted of the MPEG-4 standard and multimedia authoring tools to determine the specification and design of a prototype 2- D MPEG-4 authoring tool. The specification and design was used as a basis for the implementation of a prototype 2-D MPEG-4 authoring tool that complies with the Complete 2-D Scene Graph Profile. The need for research into MPEG-4 authoring tools arose from the reported lack of knowledge of the MPEG-4 standard and the limited implementations of MPEG-4 authoring tools available to content authors. In order for MPEG-4 to reach its full potential, it will require authoring tools and content players that satisfy the needs of its users. The theoretical component of this dissertation included a literature study of the MPEG-4 standard and an investigation of relevant multimedia authoring systems. MPEG-4 was introduced as a standard that allows for the creation and streaming of interactive multimedia content at variable bit rates over high and low bandwidth connections. The requirements for the prototype 2-D MPEG-4 authoring system were documented and a prototype system satisfying the requirements was designed, implemented and evaluated. The evaluation of the prototype system showed that the system successfully satisfied all its requirements and that it provides the user with an easy to use and intuitive authoring tool. MPEG-4 has the potential to satisfy the increasing demand for innovative multimedia content on low bandwidth networks, including the Internet and mobile networks, as well as the need expressed by users to interact with multimedia content. This dissertation makes an important contribution to the understanding of the MPEG-4 standard, its functionality and the design of a 2-D MPEG-4 Authoring tool. Keywords: MPEG-4; MPEG-4 authoring; Binary Format for Scenes.

  • Description: Central to the tumultuous student protests of 2015 and 2016 was an urgent call for the decolonisation of South African universities. Existing curricula, including teaching and assessment practices, as well as institutional cultures and structures were challenged. Against this backdrop, in this article we focus on the academic leadership role of Heads of Departments (HoDs) at Rhodes University. In this small-scale project we interrogate how HoDs conceptualised their roles in this uncertain and complex context. From the data analysis a number of tensions emerged in the ways in which they articulated and enacted their roles. The findings indicate that the protests have contributed to the increasing complexity of the role of an HoD. Issues raised during the protests catalysed HoDs at Rhodes University, some for the first time, into considering the implications of the decolonising call from students and into exercising stronger transformative leadership roles.

  • Description: Ever since union - and before - black South Africans have been excluded from parliament, provincial councils and other law-making bodies. This means that blacks have never participated in the electoral process. The voting (electoral) system - its nature and workings - remained the sole preserve of white political parties and the Apartheid government of the day. As a result of a conjuncture of circumstances (as per Harare Declaration), the African National Congress and the apart0heid government are now engaged in talks. Hopefully this will ultimately lead to negotiations towards a new Constitution which will make provision for a single unitary, non-racial, non-sexist South Africa with universal franchise on one single common voters roll and one person one vote. Part of the process of constitution-making for such a South Africa, will be the working out of a system of voting, an electoral system, which would be appropriate for the country. The African National Congress has recognised the need for a multi-party system, the right of all other political forces and organisations to organise and to compete for power on the political terrain. The ANC also recognises that all parties enjoying significant support should have the right to be represented in a Constituent Assembly and parliament. The question which needs to be resolved is: What would be an appropriate electoral system to achieve the stated objec0tive? It is to place the issue before the people of our country and to ensure participation at the widest levels by all the organisa0tions of the people in the process of constitution-making (including formulating and/or agreeing upon an acceptable system of voting), that the African National Congress, Community Law Centre (University of the Western Cape) and the Centre for Development Studies have organised a conference to be held in the Western Cape on 2 - 4 NOVEM0BER 1990. This conference will not be a decision-making one. nor will there be any resolutions at the end of the conference. The objective is to facilitate meaningful discussions throughout the country. To facilitate this process, we present a discussion document entitled "ELECTORAL SYSTEMS: A CRITICAL SURVEY" which has been prepared by Professor KADER ASMAL, a member of the Constitutional Committee of the ANC and Professor of Law at Trinity College, Dublin. It is hoped that arising from these discussions, there will be more meaningful discussions and consultations amongst or0ganisations such as trade unions, civic organisations, women’s organisations and other sectoral or0ganisations - ultimately leading to a situation which we would be better able to decide on an acceptable, unity building and democratic electoral system. , "The Community Law Centre (UWC) & Centre for Development Studies in conjunction with the ANC Constitutional Committee."--Cover

  • Description: The study examines the relationship between demarcation of municipal boundaries and the capacity of a municipality to deliver services. The case of the amalgamation of Baviaans, Camdeboo, and Ikwezi local municipalities which has led to the establishment of the Dr Beyers Naudè Municipality in the Sara Baartman District Municipality in the Eastern Cape has been used to determine this relationship in this study. The amalgamation of these municipalities has led to the redetermination and dismantling of their boundaries and the establishment of the boundaries of the newly created and larger Dr Beyers Naudè Local Municipality. The study investigated whether the demarcation of municipal boundaries has, in this instance, enhanced the capacity of the municipality to deliver basic services. Organisational Theory was used to interpret the amalgamation of municipalities. This theory was used for the theoretical basis of organisational structure and highlighting the need for the alignment of organizational structure with the municipalities’ mandate, of effective and efficient service delivery. The study adopted a qualitative research method and employed a non-probability purposive sampling technique to select participants. Interviews were used for data collection. 38 participants were interviewed, namely 7 councillors, 5 municipal officials, 5 members of the ratepayers’ association and 21 members of the community. Mixed views were expressed by participants regarding the enhancement of the state on basic service delivery after the merger of the three local municipalities. Furthermore, the study did not find evidence of a feasibility study prior to the implementation of the amalgamation process. Subsequently, the study could not find conclusive evidence relating to the enhancement of the capacity of the municipality to deliver services after the redetermination of municipal boundaries. The study recommends, among others, that the demarcation of municipal boundaries should be preceded by an appropriate feasibility study and be done such that there is compliance with the relevant legislation, and it must also have an effective public participation. The study also recommends that the newly established Dr Beyers Naudè Local Municipality should focus on maintaining the service delivery infrastructure it has inherited from the merger of its three predecessor municipalities, enhance public participation in its programmes, and priorities community beneficiation as a critical aspect of its service delivery mandate. , Thesis (PhD) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021

  • Description: This study is about records management at the Albany Museum in Grahamstown, in the Eastern Cape Province of South Africa. The objectives of the study were to find out the extent to which records management is practised; to find out what records management programme exist; to find out the infrastructure available for records management; and to identify the challenges, if any, facing records management in Albany Museum. The records life cycle and the records continuum formed the theoretical framework. The study adopted qualitative and quantitative research approaches. The state accountant, senior administrator, fossil excavator, receptionist and the postgraduate researcher formed the sample of the study. Quantitative data were coded and analysed using Microsoft Office Excel 2013 while the qualitative data were analysed using thematic analysis. The major findings showed that records management Albany Museum is very weak, which makes it difficult for the museum to derive or benefit from effective records management as well as experiencing delays in decision-making, loss and misplacement of records. Also, it was revealed that there was no personnel responsible for the records management. The study recommended for recruitment of personnel for records management in the museum to improve on records management as well as the development of a functioning records management program

  • Description: The skills shortages in mining and mineral sector had existed for a decade and had a widespread effect on South Africa economy. It affects the level of economic productivity and reduces the country’s capacity to develop a knowledge society. This, in turn, affects the country’s functioning in the global economy. Despite the sector’s best efforts, the shortages continue to grow and threaten the delivery of projects and growth plans. Some researchers contend with the view that the persistence of skills shortages in mining and mineral sector is largely due to entrenched attitudes among both the industry and the community. They claim that employers have the means to change the educational profile of the subsectors by appointing recruits with higher levels of schooling. However, owing to the limited number of higher educated people living in the communities surrounding the mining operations and lack of interest in mining of people with higher levels of education, to name but few, employers are perceived to have a habit of employing people with little skills. The current study was aimed at investigating the impact of skills shortage on organisational performance, propensity to leave, competitive advantage and sustainability, from the management perceptive. The main objective of this study was to incorporate and embed previous research findings and theories into a comprehensive hypothetical model. A hypothetical model showed various factors that may influence skills shortage. Four independent variables (working environment, employment conditions, resources and education and training) were identified as variables that may influence skills shortage; and mediating variable (skills shortage) was also identified as a variable that have potential to affect dependent variables (organisational performance, propensity to leave, competitive advantage and sustainability) of gold mining sector. Furthermore, eight hypotheses were developed to test the relationship between independent, mediating and dependent variables. All these variables were clearly defined and operationalized with various items obtained from measuring instruments used in other similar studies. A purposive sample of 343 respondents was drawn from the population. A seven-point Likert scale and structured questionnaire were administered in person to the respondents and of which 300 were usable and subjected further to several statistical analyses. The validity and reliability of the measuring instrument was evaluated using significant effect p< = 0.001 and Pearson’s correlation test (α = 0.05). Data gathered were fed to and analysed by STATISTICA (version 10) and factor analysis and regression analyses were the statistical procedures used to test the significance of the relationships between the various independent and dependent variables. Consequently, working environment, resources and education and training were three independent variables that were identified as having ability to predict propensity to leave, competitive advantage and sustainability. An attempt was made to establish whether various demographic variables have an influence on mediating and dependent variables through the introduction of gender and position in the organisation while conducting an Analysis of Variance and Multiple linear regressions, but they obtained negative values. The conclusion is that demographic variables do not have over mediating and depended variables. The findings of this study states that with conducive working environment, availability of resources, the high levels of education and training, the country could produce skills that would reduce propensity to leave, drive competitive advantage and sustainability, innovation and entrepreneurship, create competitive advantages and boost employment sustainability.

  • Description: Confession is a central disciplining technology deployed in the second series of Intersexions, a popular South African TV series that seeks to change sexual and social behaviours that contribute to the risk of HIV infection. The article considers the ‘edu’ part of this edutainment programme, specifically with the nature of the lessons and with the form of ‘disciplining’ the narratives presuppose for gendered and sexual subjects. Central to this critical and constructivist exploration of the gender relationships that are validated and expurgated are Foucault’s notions of discourse and confession as a technology of self. We argue that the series presents a range of different gendered and sexual subjectivities but implicitly endorses a modern subjectivity and transformation at the level of the individual.

  • Description: The importance of properly securing an organization’s information and computing resources has become paramount in modern business. Since the advent of the Internet, securing this organizational information has become increasingly difficult. Organizations deploy many security mechanisms in the protection of their data, intrusion detection systems in particular have an increasingly valuable role to play, and as networks grow, administrators need better ways to monitor their systems. Currently, many intrusion detection systems lack the means to accurately monitor and report on wireless segments within the corporate network. This dissertation proposes an extension to the NeGPAIM model, known as NeGPAIM-W, which allows for the accurate detection of attacks originating on wireless network segments. The NeGPAIM-W model is able to detect both wired and wireless based attacks, and with the extensions to the original model mentioned previously, also provide for correlation of intrusion attacks sourced on both wired and wireless network segments. This provides for a holistic detection strategy for an organization. This has been accomplished with the use of Fuzzy logic and neural networks utilized in the detection of attacks. The model works on the assumption that each user has, and leaves, a unique footprint on a computer system. Thus, all intrusive behaviour on the system and networks which support it, can be traced back to the user account which was used to perform the intrusive behavior.

  • Description: This study investigates the literary activities of two emerging female Kenyan writers, Claudette Okwiri Oduor and Jacqueline Ndinda Kioko, both of whom are award-winning authors. Oduor won the 2014 Caine Prize for African Writing while Kioko bagged the Wasafiri New Writing Fiction Award 2017. It examines specifically how the writers deal with memory and mourning in negotiating between the past and future. I explore how their fictional and non-fictional narratives assist individuals and groups to confront loss, reconstruct new identities, and renegotiate belonging amidst personal and social upheaval. The fictional narratives at the centre of this research are Oduor’s “The Plea Bargain” (2011), “My Father’s Head” (2013) and “Rag Doll” (2014), and Kioko’s “Sometime Before Maulidi” (2014) and “Some Freedom Dreams” (2017). The study explores the themes of mental illness, existential crisis, and fragmentation, and considers bereavement, queer relationships, cultural freedom, and social recognition. The research further considers the active participation of these two writers in Kenya’s contemporary literary-cultural conversations, which span different genres and various media platforms, including blogs, YouTube clips, online magazines, and social media networks in dialogue with other writers. I trace the significance of the literary-cultural link these authors have with their local, continental, and global counterparts in countries like Uganda, Nigeria, and South Africa. The link finds expression through their (in)direct association with some of the new online publishing outlets in Kenya like Jalada Africa, Enkare Review, and Kikwetu. More importantly, their shared participation in and association with such international awards and scholarships as the Commonwealth Short Story Prize, Kwani Trust Manuscript Project, and Miles Morland Foundation is integral in apprehending contemporary literary exchanges and multidirectional flows of publishing in Africa and beyond. I equally illustrate how mentorship of younger writers through local writers’ organisations and collectives like AMKA and Writivism help in the formation of an alternative canon other than the mainstream. The study affirms that the authors seem to transcend the boundaries of production and circulation by fluidly moving between electronic and non-electronic platforms, thus mimicking the memory production of remembering, repeating, and working through.

  • Description: The private and social returns to education literature share the same conclusion: that education is beneficial for both the individual and society. However, the theoretical underpinnings are flawed as the literature does not account for the main feature that leads to the acquisition of education: the private demand for education. An understanding of the factors that motivate the individual to invest in education would lead to a deeper insight as to why both private and social returns to education exist, and would provide a clearer framework on which to base the government funding of education. This thesis provides a first attempt at filling this gap by introducing a method of estimating the returns to government investment in education, which is labelled the ‘labour market drop-out rate approach’. The approach focuses on the social return to education, not in terms of graduate earnings, but in terms of the interaction of the graduate with the economy. The approach introduces a measure of expertise utilisation, based on the premise that there is no social return to an individual acquiring education if he or she does not utilise the acquired knowledge base on entering the labour market. The approach is tested using the labour market for marine scientists in South Africa as a case study. In this case the private demand for education is found to be heavily influenced by the provision of student bursaries from the National Research Foundation, with a resulting estimate of the social return to a degree in marine science being a mere 20% to 25%. Owing to this, a new approach to government investment in marine science is introduced, that of graduate contribution schemes. Of broader significance is the ease of application of this approach, it may be adopted to analyse any funding programme in which a government may decide to invest. As such, the labour market drop-out rate provides an extension to the returns to education literature through its theoretical dealings of the private demand for education, as well as a practical tool which government agencies can use to evaluate the efficacy of any government funding of education.
