- Description: This study reports research on how student teachers in Science at Mutare Teachers' College in Zimbabwe worked with indigenous knowledge practices in relation to science concepts in the secondary school syllabus. The study was conducted among first-year science students and involved them in developing science learning activities for a peer-teaching process that was part of their course. The research was undertaken during a review ofthe college syllabus and as a study to inform the Secondary Teacher Training Environmental Education Programme (ST²EEP). The research design involved the researcher in participant observations and interviews with rural people to document indigenous knowledge practices and to develop materials for the students to work with in the lessons design part of the study. The student teachers used the documented practices to generate learning activities and lesson plans to teach the science concepts they had identified. A peer review session and focus group interviews followed the lesson presentations. Findings from the research point to the rural community being a repository of diverse indigenous knowledge practices. Student teachers showed that they had prior knowledge of both indigenous knowledge practices and science concepts when they come to class. Student teachers were able to relate indigenous knowledge practices and science concepts in ways that have the potential to enhance the learning of science in rural school contexts that lack laboratories and science equipment. The scope of the study does not allow for anything beyond tentative conclusions that point to the need for further work to be undertaken with student teachers and for the research to be extended to teaching and learning interactions in schools. Recommendations are also made for further resource-based work to be undertaken within the forthcoming St²eep implementation phase in 2007.

- Description: This study investigates the constructions of land expropriation without compensation (LEwC) in the discourses of two mainstream media, Moneyweb and City Press, and two ground-up platforms, Afriforum and the African Farmers’ Association of South Africa (AFASA). It follows the February 2018 adoption by Parliament, of LEwC as a policy to reorder the country’s unequal and racially bifurcated economy. The motivations for, and opposition to the policy locate land as ‘the issue’ in conquest and capitalism. How land is signified therefore, is important to the understandings of ‘restitution’ and/or ‘resolution’. The news platforms selected here are diverse: Moneyweb focuses on investments. City Press concerns itself with politics. Afriforum and AFASA are alternative sphericules linked to ethnically- polarised quotidian concerns with land as a key focus. Discourses are central to how citizens see and construct themselves and one another as subjects. As such, media frames can be connected to justice and inter-‘race’ complexities. This is a study of media influences in cultivating certain meanings and understandings of tenuous and fractious political situations characterised by inequality and interracial enmity. The thesis draws from the Epistemologies of the South as well as Marxism to constitute the locus of its enunciation of colonisation, liberal capitalism, land question, justice, ideology, discourse, and framing. This framework is geared towards emic understanding of interrelated local and global contexts of the land question. Conceptual clarity is key to the development of an emancipatory imagination. Qualitative framing analysis and critical discourse analysis are used in this study to examine a diachronic corpus of 124 articles from the four platforms covering 167-days, from the adoption of the LEwC motion through the initial round of public hearings. The findings suggest a strong influence of the structures of coloniality in discourses across a wide political spectrum. The frames and counter-frames in the four platforms are simultaneously divergent and similar. Some are reactionary and conservative, others are liberal-transformational and even radical-prefigurative. All however, orbit around abyssal, North-centric, liberal capitalist normativity as the centripetal centre. The study proposes rethinking of the land question, a radical exorcism from land discourses, of structures of coloniality of power, knowledge, and being. Their mobilisation, predominance and naturalisation in political communication is anti-transformation and helps keep Black South Africans to this day, under the heavy yoke of an oppressive colonial and Apartheid reality as perpetual economic slaves. , Thesis (PhD) -- Faculty of Humanities, Journalism and Media Studies, 2022

- Description: That natural resources (NRs) are important to those experiencing adversity, and, especially, vulnerability associated with HIV/AIDS, is well documented, particularly with respect to food and energy security. What is unclear is where HIV/AIDS ranks in terms of its significance in comparison to other household shocks, the role local ecological knowledge may (LEK) play in households' response to shock, a propos the types of coping strategies that are employed. Consequently, this research aims to bridge the knowledge gap between HIV/AIDS and the degree to which it is contributing to the expansion of NR commercialisation and to explore the unknowns surrounding the influence of LEK on people's choice of coping strategy. A two phase study was designed to provide quantitative rigour with qualitative depth. Phase one was an extensive, rapid survey of NR traders within urban and rural settings in five southern Africa countries. The principle objective was to profile the trade, the livelihoods of those involved and their reasons for entering the trade, to ultimately establish to what degree HIV/AIDS may have been a catalyst for this. Almost one third of the sample entered the trade in response to illness and/or death in their households, with 80% of deaths being of breadwinners. The findings illustrated considerable dependence on the sale of NRs; for almost 60% of the sample it was their household's only source of income. There was evidently increased blurring of the lines between rural and urban NR use with a greater diversity of products being traded in urban areas. Phase two involved in-depth interviews and work with a smaller sample at two sites selected based on the findings from the first phase. It incorporated three groups of households; non-trading, inexperienced trading and experienced trading households. Key areas of focus were household shocks, coping strategies employed in response to these and the role LEK may be playing in the choice of coping strategies. Within a two year period, 95% of households registered at least one shock, of which 80% recorded AIDS-related proxy shocks. Non-trading households were significantly worse-off in this regard, while in the case of non-AIDS proxy shocks, there was no such difference between groups. The most frequently employed coping strategy was the consumption and sale of NRs and was of particular importance when households were faced with AIDS proxy shocks. Trading households emerged as having superior levels of LEK in comparison to non-trading households, even for non-traded NRs, suggesting that prior LEK of NRs opened up opportunities to trade in NR as a coping strategy. Further inspection of the latter group however revealed that the portion of non-trading households who traded on a very ad hoc basis actually had comparable levels of LEK to the trading households. Despite the ad hoc trading households' vulnerable state and their disproportionately high level of AIDS proxy measures, they had at their disposal, sufficient LEK to unlock certain key coping strategies, namely the NR trade. In this sense there are apparent linkages between LEK, HIV/AIDS and the expansion of the commercialisation of NRs.

- Description: Research suggests that queer people face both general discrimination and inadequate support in substance use disorder (SUD) treatment. One recommendation made by scholarship to address this is to improve the treatment capabilities of practitioners, thus improving practitioner readiness and reducing access barriers for a potentially at-risk population. The purpose of this study is to explore SUD treatment practitioners’ experiences of treating queer clients and identify their training needs. Semi-structured interviews were conducted with seven registered mental healthcare practitioners operating in Cape Town, South Africa. Data was analysed via thematic analysis, using a social constructionist approach to gender and practitioner knowledge. The findings reflect a strong interest in gender-sensitive training to better prepare practitioners for treating queer clients. Participants provided feedback on areas in need of improvement and made recommendations on how training should be conducted. Findings indicate that queer clients may enter treatment with a high burden of trauma due to discrimination, and that healthcare structures abiding by a binary approach to gender may not be able to address queer people’s diverse needs. Recommendations for future research are made, with particular emphasis on including queer people in surveillance data. Target areas for training programmes are described, with emphasis on terminological understanding and accessibility of training. , Thesis (MA) -- Faculty of Humanities, Psychology, 2022

- Description: Orientation: Several policies have been formulated by the government to redress the inequalities of apartheid. However, the policies have not yielded any positive results as many graduates from Historically Disadvantaged Institutes (HDIs) continue to struggle in the open labour market as compared to graduates from Historically Advantaged Institutes (HAIs). This has been mainly attributed to the legacy of apartheid in several previous studies. As a result, most of these previously disadvantaged individuals (mostly Black Africans) struggle to make the transition from higher education into the world of work. Research Purpose: This study thus explores the journeys of these Black African students from HDIs to understand the transition and experiences from tertiary education into the labour market. Further, the research sought to understand how these transitions and experiences manifest in a context of high unemployment. Finally, the resolution tactics used by students in such a context are given attention. Research approach, design and method: A longitudinal qualitative approach was deemed appropriate for the study as the aim was to understand the changes that occurred over time. The data was collected over a two-year period. A narrative inquiry was utilized as it allowed the participants to share their perceptions without limitations. A total of 30 participants partook in the study. The participants were selected using a purposive sampling to ensure the right participants were involved in the study. The main criteria for selection to participate was that the participants had to be enrolled with a HDI. Main findings: The narratives of the participants led to the formulation of six main themes that were regarded as affecting the transitions and experiences of the Black graduates from HDIs; namely, (1) socio-economic background, (2) education system, (3) labour market experiences, (4) geographical location, (5) social capital and (6) student resolutions to the challenges of employability. A previously disadvantaged background resulted in the participants being recipients of poor education quality, no social networks or information to navigate the labour market and limited access to the labour market due to secluded residential areas. Subsequently, most participants were unable to take responsibility of enhancing their own employability. Contribution: It is not the sole responsibility of the higher education institutes to produce employable graduates, but it's a process that should also involve government, students and employers. As long as the social inequality remains an issue in the country all the efforts to improve employability and transition into the open labour market will be in vain. Furthermore, employers must work together with higher education institutes by offering programs such as internships and career expos to enhance the employability of the graduates. A Graduate Transition Model (GTM) is suggested based on the findings of this research.

- Description: This work reports on the nonlinear optical properties of tetra - and octa substituted phthalocyanines (Pcs) utilising pentane thiol and 4-tertbutyl phenol as substituents. Their nonlinear absorption coefficient (𝛽) and absorption cross sections were determined using the Z-scan technique with a 10 ns pulse laser at 532 nm. The molecular second order hyperpolarizability Im[γ] was observed and the following Im[γ] trend was obtained for 𝛼-H2Pc(SC5H11)4 isomers, 5.93 ×10−31 (Cs) 2.24×10−32(D2h) > 1.21×10−32(C4h) > 1.05×10−32 (C2v) esu, respectively, in chloroform. Symmetry was seen to have an effect on the observed reverse saturable absorption (RSA) response. Based on the five level model rate equation nonlinear fit of the RSA response curves and Real Time Time Dependant Density Functional Theory (RT-TDDFT) results, the singlet excited state population dynamics was found to play a significant role in producing the observed Im[γ] trend. , Thesis (MSc) -- Faculty of Science, Chemistry, 2021

- Description: Organisations and people find themselves in the era of what is known as the Fourth Industrial Revolution (4IR). Unlike the preceding revolutions, this revolution is characterised by technological advancements that lead to disruptive phenomena. These advancements are growing at an exponential rate. They have brought disruptive innovations that have either reshaped many industries, causing them to lose market share or exit altogether. Some organisations are keen to embrace disruptive innovation to ensure that they are sustainable into the future, while others are only inclined to use known technologies to leverage economies of scale. The 4IR has already been around for a while and is moving at a fast pace. The level of readiness for the automotive assembler, Isuzu Motors South Africa (IMSAf), to take advantage of such technological changes brought by the 4IR, has not yet been measured. The primary objective of this study is to investigate IMSAf’s perceptions and readiness to embrace technological changes brought by the 4IR. The perceptions and readiness are assessed based on the technology embracing organisational framework of efficiencies, innovation, skills and re-training. This study is grounded in the philosophy of positivism and the related method used is a quantitative study to test the research questions in an objective manner. A questionnaire was the sole method of collecting first-hand data from the selected sample. The population size consisted of 139 respondents working in various business units within IMSAf. These individuals are occupying various roles and they have in depth, tacit, and multi-disciplinary knowledge of processes and would be the first to experience technological changes brought by the 4IR. A quantitative analysis technique is applied, such as descriptive and inferential statistics, to analyse data. A literature review on the topic was conducted as well as an empirical study. The results from both the literature review and the empirical study found that with the implementation of 4IR emerging technologies within an organisation, there is a significant improvement on efficiencies, innovation and skills and re-training. Furthermore, the level of awareness and understanding about the benefits of embracing 4IR emerging technologies within IMSAf is significant. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

The 4IR has already been around for a while and is moving at a fast pace. The level of readiness for the automotive assembler, Isuzu Motors South Africa (IMSAf), to take advantage of such technological changes brought by the 4IR, has not yet been measured. The primary objective of this study is to investigate IMSAf’s perceptions and readiness to embrace technological changes brought by the 4IR. The perceptions and readiness are assessed based on the technology embracing organisational framework of efficiencies, innovation, skills and re-training. This study is grounded in the philosophy of positivism and the related method used is a quantitative study to test the research questions in an objective manner. A questionnaire was the sole method of collecting first-hand data from the selected sample. The population size consisted of 139 respondents working in various business units within IMSAf. These individuals are occupying various roles and they have in depth, tacit, and multi-disciplinary knowledge of processes and would be the first to experience technological changes brought by the 4IR. A quantitative analysis technique is applied, such as descriptive and inferential statistics, to analyse data. A literature review on the topic was conducted as well as an empirical study. The results from both the literature review and the empirical study found that with the implementation of 4IR emerging technologies within an organisation, there is a significant improvement on efficiencies, innovation and skills and re-training. Furthermore, the level of awareness and understanding about the benefits of embracing 4IR emerging technologies within IMSAf is significant. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: Molecular films of manganese phthalocyanine (MnPc) complexes, tetra-substituted with 2-diethylaminoethanethio at the peripheral (Mn(OAc)-β-TDEAETPc, 1) and non-peripheral (Mn(OAc)-α-TDEAETPc, 2) positions were formed on glassy carbon electrode by electropolymerization and electrodeposition respectively. Atomic force microscopy images confirmed the presence of the films and revealed significant morphological differences. The films exhibited an electrocatalytic activity towards the oxidation of the insecticide, bendiocarb. Hydrodynamic technique, using rotating disc electrode voltammetry, was used to investigate the kinetics of electro-oxidation of the insecticide. Morphological differences of the films significantly influenced kinetic parameters. Values of Tafel slopes, obtained from Tafel plots, suggested that catalysis of bendiocarb occurred via outer sphere mechanism.

- Description: The construction industry has become the significant player in the economy of many developed and developing countries in the world. The industry contributes to the Gross Domestic Product (GDP) and employment rate of many nations. As such, the industry is the engine for the economic development and growth across the world. Recently, African countries have received global attention due to its calls for massive infrastructure development and maintenance thereof. Accordingly, the South African government has adopted a National Infrastructure Development Plan (NIDP), which seeks not only to transform the economic landscape of the country, but also to support the integration of the African economies through infrastructure development. To ensure that the execution of these infrastructure projects is successfully delivered in terms of time, cost, and scope; project risk management in the construction industry has become an important area of interest in the execution and delivery of the infrastructure projects. However, the constantly increasing complexity and dynamics in the delivery of construction projects have serious effects on the risk management processes during the execution of the project. In practice, risk methods and techniques have proven to be unrealistic when using the traditional risk management approach in the context of the complexity and dynamic environments wherein construction projects are delivered. Worryingly, project management practitioners in engineering and construction projects still lack the holistic and systematic insight and understanding of construction projects when applying the risk management procedures in the complex and dynamic projects environments. As a result, there are growing reports of unsatisfactory delivery of construction projects in terms of time, cost, quality, and environmental objectives. In this regard, the call for embracing the systems thinking paradigm as the alternative approach that will provide more clarity in dealing with the complex management challenges and which will gradually substitute the traditional theoretical approach of dealing with construction project management, is becoming prominent. Against this background, this study uses a multiple case study approach to explore how a systematic risk management approach could be developed and applied towards successful delivery of construction projects, and subsequently to propose a systematic risk management model that is designed to depict and grasp the underlying complexities and dynamics embedded ix | P a g e in construction projects. The choice of the case study design is founded on its utility and appropriateness for in-depth investigations into phenomena in its context as well as its usefulness for exploratory studies. Therefore, to explore the risk management phenomenon in real-life settings, the unit of analysis in this study was based on three construction projects built in one of the new Institutions of Higher Learning in South Africa during the period between 2017 and 2019. Notwithstanding the unique characteristics of these projects, the complexity and dynamic environments of these projects also emanated from the facts that i) the successful delivery of the projects was a predecessor activity to the academic schedule and activities; ii) this was one of the first universities to be built by the democratic Republic of South Africa; and, iii) the construction contract used for the delivery of the construction projects is relatively new to the professionals in the country’s construction industry. This qualitative case study design has its backbone in the constructivism philosophical paradigm which is underpinned by the ontology that there are multiple realities as conceptualized, experienced, and perceived by the people in their real-life situations or natural settings. Accordingly, the construction professionals, projects’ documents as well as field work observations were purposively chosen as the essential and reliable methods of data collection for this case study. For analysis, a conventional content data analysis methodology was applied on the empirical data that was obtained from the multiple data sources to provide a clearer understanding of the contexts in which the risk management for construction projects is performed. Accordingly, a qualitative data analysis software system called MAXQDA was used to enable the performance of data coding, managing coding, and eventually the retrieving of the coded segments in a form of visual models and summary tables. Ultimately, the qualitative content analysis approach in this thesis was performed in terms of a ‘critical filter of thick description’ which involved a balanced approach between the deductive analysis and the inductive analysis processes. With the assistance of the MAXQDA, performing the multiple levels coding and analysis processes in this thesis has not only been efficient, but also more reliable. To shed insight into the empirical findings of the study, a hybrid theoretical framework has been applied in the discussion and interpretation of the findings. The theoretical framework of this study is underpinned by the complexity theory and the theory of systems engineering. The applicability of these theories in this study is essential in providing a x | P a g e systematic and logical explanation of the practices of risk management in construction projects and further helps to explain why particular events occurred in the processes of risk management. Eventually, the theoretical framework has enabled the designing and developing of a systematic risk management model that will assist in depicting and grasping the underlying complexities while supporting proactive decision making in the delivery of construction projects. To this end, this study has made several major contributions in three multiple folds in the body of knowledge. Firstly, this study makes theoretical contributions by developing an empirically underpinned systematic risk management model which provide more clarity on comprehending the multifaceted and complex risk factors embedded in construction projects. Secondly, the qualitative case study approach and the associated analysis methods thereof in this thesis provides novelty and lays the groundwork for future research and methodological replicability in another similar phenomenon elsewhere in the world. Thirdly, this study has gone some way towards expanding the understanding and the basis for managerial decision making in relation to front-end planning and proactive approach for risk management, and eventually to improve projects’ performances on cost, time, scope, and environmental sustainability. In this regard, the key practical implication for project management practitioners is that the adoption and embracing of the systematic and holistic thinking approach in the risk management processes could enhance the successful delivery of construction projects. In the literature, there is paucity and need for more research into the exploration and analysis of the integration and interplay between the systems engineering and complexity perspectives and the other knowledge areas in the PMBOK. In conclusion, this thesis therefore argues that to address the deficiencies in risk management practices during construction projects’ delivery, the solution requires a paradigm shift from the traditional linear approach which, by design, overlooks the complexities, non-linearity and interdependences of the elements that are underpinning and characterizing the nature of the contemporary construction projects. Therefore, this thesis supports the increasingly emerging debate on the discourse that the superior traditional and linear approaches do not solve the current problems, and as such they should be replaced with the systems and holistic thinking approach that will provide more clarity in dealing with the complex management challenges in contemporary construction projects. , Thesis (PhD) -- Faculty of Engineering, Built environment and Information Technology, School of the built Environment 2023

- Description: Partnership between schools and parents seems to substandard, leading to both parties questioning each other on why children underperform. Most parents view the school as an instrument for the achievement of children and parents with limited or no education may have little or no interest in supporting children’s academic work. The aim of this study was to investigate how parental involvement in children’s academic work can be enhanced. It focused on three rural secondary schools in the Amathole West Education District in the Eastern Cape Province of South Africa. The study particularly investigated how school schools involved parents in children’s academic work and how they, together with principals, teachers and learners view their involvement in children’s academic work. Guided by Epstein’s theory of parental involvement, this qualitative study was premised on the interpretative paradigm. Face to face interviews and focus group discussions were used to collect data from three high schools in the Amathole West Education District. Purposive sampling was used to select participants who comprised a target population of 24 participants. It emerged from the data that although schools were trying to involve parents in children’s academic work, their activities were uncoordinated, occurred at school level rather than classroom level and focused less on learners’ academic work. Parent’ involvement in their children’s academic work was not touching the real curriculum issues; rather it touched on the outside. The data also showed that parents’ academic statuses influenced their participation as those who had little education seemed to be reluctant to participate on academic issues. The study concludes that there was lack of coordinated strategies by schools to involve parents in children’s academic work. The study, therefore, recommends that Coordinated Grade-based Parent-Teacher Forums be established. This will assist in opening a planform for teachers and parents to engage on teaching and learning discussions and curriculum debates.

- Description: Rural schools generally find it hard to function effectively for a variety of reasons, and managing and leading these schools brings additional challenges. This study explored the role of the principal in an academically successful rural school in Namibia. It drew on leadership theory and findings from related studies to make sense of this particular case of leadership against the odds. Using the interpretive orientation, the research explored selected organisation members’ perceptions of the principal’s leadership through semi-structured interviews. The study found that the actions and attitudes of the leader had a significant influence on the school’s performance. The manner in which the principal conducted himself, the shared vision he encouraged and his insistence on associating with all stakeholders involved in education, were instrumental in the organization’s positive achievements. The principal was shown as committed and a leader with good interpersonal working relationships. The study also revealed that this principal was both a person- and taskoriented leader, and closely resembled the ideals of transformational leadership. This study further found that, through the principal’s instructional leadership, teaching and learning are seen as the core of the school’s activities. Finally, the principal’s leadership role opens the school to the community and results in strong and mutually beneficial relationships between the school and its community.

- 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: 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.
