- Description: [Extract from message from Minister of Higher Education, Hon. Naledi Pandor]: It gives me great pleasure to endorse the 7th edition of Study South Africa. The International Education Association of South Africa (IEASA) has once again produced a publication that provides valuable insights and information about South African public universities and their place in the global higher education arena I welcome this publication and congratulate IEASA for its hard work in promoting our higher education institutions internationally. Study South Africa gives a comprehensive picture of higher education in our country. At a glance, the enquirer is able to see all that South African higher education has to offer diversity in terms of institutions, the wide range of affordable courses on offer, the international acceptability of South African qualifications as well as the rich multi-cultural experiences of our campuses. In short, the Guide provides a summary of everything that will assist the potential student to actualise his or her full potential. South African higher education is founded on broad social values such as respect for human life and dignity, commitment to equality and human rights, respect for diversity and nonsexism. Our education system seeks to construct citizens who are conscious of these values and therefore aware of their responsibilities in life and in the lives of others. These values are reflected in the diverse offerings by institutions covered in the Guide. In addition, we have specific mechanisms in place to facilitate internationalisation, and our immigration policies have been relaxed to make it easier for international students, academics and other higher education staff to enter the country and stay for the duration of their planned activity. We also subsidise students from the continent in terms of our policy on the state subsidisation of foreign students at higher education institutions. South Africa shares the global concern about the digital and information divide. We are of the view that access to information is empowering and would therefore like to see as many citizens of our country and the continent connected with the rest of the world, both digitally and in terms of knowledge. By staying in touch with the rest of the world through information sharing and exchange programmes, we minimise this information gap. It is for this reason, therefore, that the work of IEASA in the form of this publication is applauded, because it seeks to promote such exchanges and information sharing. There is no question that through internationalisation we can impact on our political, economic, cultural and social transformation. We can also address our skills shortage, build research capacity, enrich curricula and enhance the student experience. Collectively higher education institutions in South Africa offer an impressive array of information and communication technologies, well stocked and interconnected libraries and some scholars who are among the best in the world, making the country a destination of choice for both Africans and students from abroad. We aspire to make all our international partners, students and staff feel at home and content with what our institutions offer them, pleasant living and study or work environments. We want them to be proud of their association with South African higher education and be ambassadors for the system once they leave South Africa. , 7th Edition

- Description: The main purpose of this review article was to highlight some of the physical consequences of sitting for prolonged periods in a confined setting. More specifically, the review relates this research to call centre work and where applicable comments on the limited literature relating specifically to ergonomics research within call centre settings. In particular the article explores the biomechanical stresses placed on the musculoskeletal system during prolonged sitting at a workstation, and the physiological consequences thereof. The paper then provides possible solutions to reduce the physical strain placed on these workers by looking at workstation design and work organisation emphasizing worker education and the promotion of worker well being.

- Description: In this work we discuss different approaches for achieving electrodes modified with N4 macrocyclic complexes for the catalysis of the electrochemical oxidation of thiols. These approaches involve adsorption, electropolymerization and molecular anchoring using self assembled monolayers. We also discuss the parameters that determine the reactivity of these complexes. Catalytic activity is associated with the nature of the central metal, redox potentials and Hammett parameters of substituents on the ligand. Correlations between catalytic activity (log i at constant E) and the redox potential of catalysts for complexes of Cr, Mn, Fe, Co, Ni and Cu are linear with an increase of activity for more positive redox potentials. For a great variety complexes bearing the same metal center (Co) correlations between log i and Eo′ of the Co(II)/Co(I) couple have the shape of an unsymmetric volcano. This indicates that the potential of the Co(II)/Co(I) couple can be tuned using the appropiate ligand to achieve maximum catalytic activity. Maximum activity probably corresponds to a ΔG of adsorption of the thiol on the Co center equal to zero, and to a coverage of active sites by the thiol equal to 0.5.

- Description: This study originates out of my experience as an environmental educator working within business and industry in Zimbabwe and South Africa. It is motivated by my observation that, despite much environmental rhetoric and training, environmental education in industry rarely leads to significant advances towards environmental protection. I assume that the problem of the mismatch between rhetoric and action involves both semiotic and non-semiotic components and therefore, after a thorough exploration of my methodological options, I adopt a qualitative transdisciplinary textual analysis of relevant documents using Fairclough’s Critical Discourse Analysis and Bhaskar’s Dialectical Critical Realism, with some insights taken from Bhaskar’s more recent concept of Meta-Reality. My main conclusions from the study indicate that causally efficacious philosophical mistakes, relating to theories of structure/agency and theories of epistemology, are an important aspect of the problem being considered. Specifically, I demonstrate that these mistakes function to buttress ideology and its attendant contradictions which in turn function to provide the preconditions that maintain inequalities and poor environmental practice in business and industry. Prior and current events, such as climate change and the trend towards globalisation, the ‘free market economy’ and psychological characteristics of the author, relevant to the problem, are also important. In line with Bhaskar’s emancipatory aim for explanatory critique, I end with tentative recommendations for a re-imagined environmental education for business and industry which require (un)action. Consistent with my methodological choices, my recommendations have a (qualified) universal application, despite my focus on texts from South Africa and Zimbabwe. My recommendations are summarised below: • there should be consistency between theory and practice such that performance contradictions are avoided; • we should not act from a fear of survival based on past, no longer relevant experiences (e.g. from childhood) as this is unlikely to be an adequate base for present actions; • we should avoid voluntarism by acting with the resources at our disposal, based on a true understanding of our strengths and weaknesses and our own specificities; • we should avoid assuming the stance of the ‘victim’ by refusing to blame other agents or circumstances, without distorting or underestimating the causal efficacy of those agents or circumstances (related to avoiding voluntarism, whilst nevertheless not resorting to determinism either); • we should direct our action towards the abolition of inequalities and master-slave relationships (related to the avoidance of performance contradictions); • we should act from the position of epistemological humility, rather than from the position of epistemological privilege; • we should consider action as ‘shedding’ based on an understanding of the Transformational Model of Social Activity (TMSA); and • we should consider learning to be ‘shedding’ based on the necessity of (un)knowledge, or ignorance, as a requirement of arriving at relatively new knowledge. This study is also a contribution to contemporary methodological discussions relevant to Critical Discourse Analysis in that it extends these discussions to include psychoanalytical (as well as the more familiar phenomenological and ideological) depth explanations of lived illusion. Furthermore, this study is an experimental attempt to apply the concept of ‘meta-reflexivity’ in Critical Discourse Analysis.

- Description: The question of subjecthood has dogged linguistic science since ancient times. However, in current versions of Minimalism, subjects do not have primitive status and can only be defined in derived terms. However, subjects and the broader theoretical notion of SUBJECT remain important in linguistic description. This paper develops a definition of subjecthood in terms of set-theoretic notions of functional dependency: when a feature, say phi, determines the value of some other feature, say u-phi. This notion is used to describe various phenomena where subjecthood has been invoked: binding domains and subject-oriented anaphors.

- Description: The start of the twenty-first century was marred by a spate of company collapses that involved fraudulent accounting activity. In many cases, company executives, many of whom belonged to the accounting profession, perpetrated the fraud. As a result, internationally, the accounting profession has suffered an enormous loss of goodwill, and its reputation as a profession with integrity has been severely harmed. Accounting professionals are no longer accorded the high regard they commanded in the past. The consequences for the profession have been far-reaching: accounting now faces a long, uphill battle to restore its reputation and to regain the trust of the international business community. This study replicates two famous international studies in the South African context. The focus of the study was to establish whether factors such as the Code of Professional Conduct of the South African Institute of Chartered Accountants (SAICA), the corporate ethical environment and their age influence the ethical judgement of individual accountants. The first such study was conducted in the United States of America (USA), and it was followed by similar research in Turkey. The results of these two studies suggested very different factors that could influence accountants' ethical judgement. The study reported in this article investigated South African chartered accountants; and its results were similar to those obtained in the US study.

- Description: When the new democratic government came into power, much legislation, policies and strategies were transformed, included was the welfare system that was imbalanced, unjust, discriminatory and inappropriate. It was replaced by a developmental approach that is more just, equitable and appropriate system contained in the White Paper for Social Welfare (1997). Social workers were expected to reform their method of intervention. Consequently, this study will focus on the experiences of social workers as changes were brought into the approaches used in service delivery. The goal of the study is to explore and describe social workers’ experiences on the transformation of social welfare from a traditional remedial approach to a developmental approach. The study was conducted using the qualitative research approach. The research study made use of an explorative, descriptive and contextual design. The researcher used purposive and theoretical non-probability sampling methods to draw the sample. Data was collected through semi- structured interviews. The data was analyzed using Tesch’s eight steps in Creswell (1994:155) and was verified against four criteria that Guba in (Krefting, 1991) developed for testing the trustworthiness of a qualitative study. Based on the findings and conclusion of the study, recommendations were made to the management of the department of social development on how to address the challenges facing social workers on the implementation of the developmental approach. The results will be disseminated by means of a written research report.

- Description: Although fire is recognized as an integral component of savanna dynamics, there is a dearth of understanding of its impacts on woody plant seeds. This study examined the impacts of fire in stimulating or constraining post-fire germination of seven common savanna woody species. Seeds of two species (Combretum hereroense and Euclea natalensis) failed to germinate irrespective of fire treatment. For the remaining five species, fire effects were dependent on seed location as either on the soil surface or buried. For surface seeds, fire effects reduced germination in four of the species, and stimulated it for one species (Acacia swazica). For buried seeds, fire had no effect. A significant proportion of surface seeds were destroyed by fire, and overall germination was higher for buried seed for most species other than A. swazica.

- Description: Integrated biostratigraphic (planktonic foraminifera, calcareous nannofossils), chemostratigraphic (bulk C and O isotopes) and compound-specific organic geochemical studies of a mid-Cretaceous pelagic carbonate—black shale succession of the Ionian Zone (western Greece), provide the first evidence for the Cenomanian–Turonian oceanic anoxic event (OAE2, ‘Bonarelli’ event) in mainland Greece. The event is manifested by the occurrence of a relatively thin (35 cm), yet exceptionally organic carbon-rich (44.5 wt% TOC), carbonate-free black shale, near the Cenomanian–Turonian boundary within the Vigla limestone formation (Berriasian–Turonian). Compared to the ‘Bonarelli’ black-shale interval from the type locality of OAE2 in Marche–Umbria, Italy, this black shale exhibits greatly reduced stratigraphic thickness, coupled with a considerable relative enrichment in TOC. Isotopically, enriched δ[superscript 13]C values for both bulk organic matter (−22.2‰) and specific organic compounds are up to 5‰ higher than those of underlying organic-rich strata of the Aptian-lower Albian Vigla Shale member, and thus compare very well with similar values of Cenomanian–Turonian black shale occurrences elsewhere. The relative predominance of bacterial hopanoids in the saturated, apolar lipid fraction of the OAE2 black shale of the Ionian Zone supports recent findings suggesting the abundance of N[subscript 2]-fixing cyanobacteria in Cretaceous oceans during the Cenomanian–Turonian and early Aptian oceanic anoxic events.

- Description: In most research, appropriate collections of data play a significant role in aiding decision-making processes. This is more critical if the data is being accessed across organisational barriers. Further, for the data to be mined and analysed efficiently, to aid decision-making processes, it must be harnessed in a suitably-structured fashion. There is, for example, a need to perform diverse data analyses and interpretation of structured (non-personal) HIV/AIDS patient-data from various quarters in South Africa. Although this data does exist, to some extent, it is autonomously owned and stored in disparate data storages, and not readily available to all interested parties. In order to put this data to meaningful use, it is imperative to integrate and store this data in a manner in which it can be better utilized by all those involved in the ontological field. This implies integration of (and hence, interoperability), and appropriate accessibility to, the information systems of the autonomous organizations providing data and data-processing. This is a typical problem-scenario for a Virtual Inter-Organisational Information System (VIOIS), proposed in this study. The VIOIS envisaged is a hypothetical, secure, Wireless Grid-enabled Data Warehouse (WGDW) that enables IOIS interaction, such as the storage and processing of HIV/AIDS patient-data to be utilized for HIV/AIDS-specific research. The proposed WDGW offers a methodical approach for arriving at such a collaborative (HIV/AIDS research) integrated system. The proposed WDGW is virtual community that consists mainly of data-providers, service-providers and information-consumers. The WGDW-basis resulted from systematic literaturesurvey that covered a variety of technologies and standards that support datastorage, data-management, computation and connectivity between virtual community members in Grid computing contexts. A Grid computing paradigm is proposed for data-storage, data management and computation in the WGDW. Informational or analytical processing will be enabled through data warehousing while connectivity will be attained wirelessly (for addressing the paucity of connectivity infrastructure in rural parts of developing countries, like South Africa).

- Description: This study investigates the impact of the Times of Zambia gender policy on journalistic practices. The policy was formulated to address issues of representation of women both in news coverage and at an institutional level. In spite of the implementation of the editorial gender policy, no change in gendered representation is evident. As a media practitioner and a Zambian woman concerned with social justice, I set out to investigate the impact of this policy on journalistic practices. The study is informed by a Cultural Studies approach to media studies, specifically drawing on the 'circuit of culture' (du Guy et ai, 1997) and focused on two specific 'moments', namely representation and production. Data was collected using two qualitative methods, namely document analysis and semi-structured in-depth interviews. The document analysis established that this policy is informed by a liberal feminist approach to media and identified the weaknesses in its formulation. The subsequent semi-structured in-depth interviews probed the practices and perceptions of male and female journalists and editors in relation to the degree of change in gendered representation in the news. This study finds that the editorial gender policy at the Times of Zambia has not had any significant impact on the journalistic practices and it probed the reason for this lack of effectiveness. It argues that this can be partially attributed to the orientation of the policy within a liberal feminist paradigm which neglects the internal and external factors that influence the representation of women and men in news production. Further, this position ignores the societal structures and power relations which impact, albeit unintentional, on the treatment of news. Inter-organisational factors such as profit maximisation, political interference, the use of news values and news beats are identified as leading to the exclusion of representations of women in hard news. At an intra-organisational level, lack of importance attached to the policy by senior staff and their attitudes to news production in general have meant that the policy was not enacted or ensured in any meaningful way. The study also established that the patriarchal values that characterise Zambian society influence journalists ' and editors' treatment of news, thus making the implementation of the policy ineffective. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This research examines the plausibility of developing demand forecasting techniques which are consistently and accurately able to predict demand. Time Series Techniques and Artificial Neural Networks are both investigated. Deodorant sales in South Africa are specifically studied in this thesis. Marketing techniques which are used to influence consumer buyer behaviour are considered, and these factors are integrated into the forecasting models wherever possible. The results of this research suggest that Artificial Neural Networks can be developed which consistently outperform industry forecasting targets as well as Time Series forecasts, suggesting that producers could reduce costs by adopting this more effective method.

- Description: Shortly after independence, Namibia embarked on a major process of educational reform. It was in this reform that the apartheid educational legacy was redressed. Namibians viewed the apartheid educational system as being irrelevant and that it did not meet their needs and expectations. One of the reform aims was to involve education in the development of knowledge and skills for self sufficiency and sustainable development, therefore Agriculture was incorporated into the school curriculum as a key area to achieve this aim. Learners taking the subject are expected to be equipped with relevant theoretical and practical skills that provide a sound foundation in this discipline. This case study was undertaken to gain a better understanding about how the participating teachers perceived and implemented the Agriculture curriculum at the senior secondary school level in their schools. In carrying out the case study a qualitative research method was employed using semi-structured interviews, observation and document analysis for data collection. It would appear from this study that Agriculture is unable to fully achieve the reform ideals at the senior secondary school level, as sixteen years after independence these teachers are still teaching the subject to learners with very limited resources and academic support. This scenario shows that there are marked inconsistencies between policy and praxis, between the stated goals and aims of the reform and the curriculum designed to achieve these. In this half-thesis I therefore argue that without well qualified teachers, suitable resources and infrastructure to implement the curriculum in these schools, the pre-vocational nature of the subject as suggested in the subject policy document will be compromised. The study concludes by proposing certain teaching strategies and possibilities for systemic development that can be used to effect quality curriculum implementation in the region where the research was situated.

- Description: Poverty alleviation by means of rural development has become a priority among developing countries. In turn, rural development may be significantly enhanced and supported by Information and Communication Technologies (ICTs), the use of which is highlighted by the emerging importance of information and knowledge as key strategic resources for social and economic development. An analysis of rural case studies where ICTs have been introduced, suggests that there are a number of barriers and constraints that are faced when taking advantage of these technologies. These include access to infrastructure, limited formal education, insufficient training and capacity building, financial and political constraints, and social and cultural challenges. These challenges threaten the success and sustainability of rural ICT projects. Sustainability is key to the effectiveness of a rural ICT project; therefore it is important to understand the concept and categories associated with ICT project sustainability in rural areas. The categories of sustainability which include social and cultural, institutional, economic, political, and technological, reveal critical success factors that need to be considered in the implementation and management of rural ICT projects. The project management discipline acknowledges the importance of understanding the project’s environment, particularly environmental factors associated with rural communities. The complexity of the environment therefore implies the need for a project to be undertaken in phases comprising the project life cycle. Project management practice for rural ICT project sustainability can therefore be examined, adapting the traditional project life cycle to a rural ICT project. A Rural ICT Project Life Cycle (RICT-PLC) that is sensitive to the critical success factors of sustainability is therefore proposed. In order to further investigate the phases of the life cycle of a rural ICT project, two case study investigations are explored: the Dwesa ICT community project, and the Rhodes University Mathematics Education Project (RUMEP) (MathsNet). A multiple case study analysis confirms the practices associated with the RICT-PLC model, and identifies additional characteristics, phases and practices associated with rural ICT projects. Finally, an enhanced RICT-PLC model is developed, that sets sustainability guidelines for ICT project management in rural areas and identifies the people, environments, technologies, systems, and requirements for ICTs to support rural development activities.

- Description: The objectives of this research, were to investigate the characteristics and develop a profile of the game and hunting industries of KwaZulu-Natal, and to undertake a comparison between the game and hunting industries in KwaZulu-Natal and the Eastern Cape. The comparative part of this study was completed using results obtained from a study done in 2002 in the Eastern Cape (van Niekerk, 2002). The main farming activities in KwaZulu-Natal are large livestock production and sugar cane production. In recent years, private landowners in KwaZulu-Natal have undergone a transition from livestock production to game ranching due to the problems faced and the cost implications of the HIV epidemic, stock theft, difficulties faced with changes in the labour laws and the increasing number of land claims against farmers. Although the game and hunting industries are relatively young industries in KwaZulu-Natal they contribute significantly to the economy of the province. Not only is greater conservation of the biodiversity more effective in game ranching but it is also proving to yield great economic returns. The increase in game ranching in recent years is namely due to the monetary value placed on wildlife, the increased value in ecotourism and its value as an earner of foreign exchange, less dependency on unskilled labour than that of livestock farming and lower rates of animal loss through theft compared to that of livestock farming. In KwaZulu-Natal game numbers indicate that impala have the greatest population amongst the respondents, followed by nyala, blesbok, common reedbuck, kudu and blue wildebeest, whilst other game species occur in smaller numbers. Respondents in KwaZulu-Natal indicate that nyala is the largest economic earner for them followed by buffalo, whereas in the Eastern Cape (2002), kudu and springbok provide the greatest income for the province. In KwaZulu-Natal income generated from hunting is second to that of live game sales compared to the Eastern Cape (2002) where hunting is the most important form of game utilisation in terms of income generated. At the time of this study, respondents in KwaZulu-Natal reported an income of R 15 382 397 generated from live sales and R 13 561 459 from hunting. These respondents also indicated that the total value of game utilised annually was in excess of R 30 million. Although game utilisation is occurring on a sustainable basis, there is room for greater utilisation of some game species which, if undertaken correctly, can increase the revenue for the province significantly and also contribute positively to further sustainability of the game populations. KwaZulu-Natal’s competitive advantage is derived from the fact that there is an abundance of game on the ranches, quality trophy animals are available, the number of game species available for hunting and quality of service rendered to hunters by the professional hunters and ranch owners. This study has clearly shown that there is a need for further investigation into the game and hunting industries in KwaZulu-Natal.

- Description: One of the most critical assets in most organisations is information. It is often described as the lifeblood of an organisation. For this reason, it is vital that this asset is protected through sound information security practices. However, the incorrect and indifferent behaviour of employees often leads to information assets becoming vulnerable. Incorrect employee behaviour could have an extremely negative impact on the protection of information. An information security solution should be a fundamental component in most organisations. It is, however, possible for an organisation to have the most comprehensive physical and technical information security controls in place, but the operational controls, and associated employee behaviour, have not received much consideration. Therefore, the issue of employee behaviour must be addressed in an organisation to assist in ensuring the protection of information assets. The corporate culture of an organisation is largely responsible for the actions and behaviour of employees. Therefore, to address operational information security controls, the corporate culture of an organisation should be considered. To ensure the integration of information security into the corporate culture of an organisation, the protection of information should become part of the way the employees conduct their everyday tasks – from senior management, right throughout the entire organisation. Therefore, information security should become an integral component of the corporate culture of the organisation. To address the integration of information security into the corporate culture of an organisation, a model was developed which depicted the learning stages and modes of knowledge creation necessary to transform the corporate culture into one that is information security aware.

- Description: Aquatic toxicity tests are increasingly being used in water resource management worldwide, and currently in South Africa, policy and legislation are being drafted to reflect this international trend. While standard toxicity test methods and test organisms are being considered to develop and set water quality guidelines and effluent discharge limits, it is not clear whether guidelines and discharge limits set using these standard test organisms will be sufficient to protect South Africa’s scarce water resources. As part of ongoing research to investigate the use of indigenous riverine organisms as toxicity test organisms a number of potential species have been identified, including the freshwater shrimp Caridina nilotica. For much of the history of aquatic toxicological data the bulk of the data has been generated by acute toxicity testing, based on short exposures and using mortality as the response end point. There are relatively few chronic, longterm tests with sub-lethal endpoints. However, it was recognized that information about longer exposure durations and non lethal response endpoints was needed, instead of mortality. Chronic tests can provide a more environmentally realistic measure of chemical toxicity than acute toxicity tests. Caridina nilotica has been identified as a potential standard toxicity test organism, as it is widely distributed, easy to find and it occurs in flowing waters. It is an indigenous species which can be easily cultured and maintained in the laboratory and is also ecologically important. Both adults and juveniles have been used successfully in acute toxicity tests at the Institute for Water Research (Rhodes University) and the ability to rear the organisms under laboratory conditions has allowed the development of chronic toxicity tests using C. nilotica. Chronic early life stage tests include continuous exposure of the early life stages, which are presumed to be the most sensitive for aquatic organisms. This study reports on the embryonic development of C. nilotica at the culture temperature of 24⁰C. Morphological developmental stages were monitored and measured and 7 developmental stages were identified. Based on the measurements of the features that were identified, toxicity tests using the reference chemicals sodium chloride (NaCl), sodium sulphate (Na₂SO₄) and cadmium chloride (CdCl₂) were undertaken to test the suitability of C. nilotica embryonic development for chronic toxicity tests for use in water resource management. The length, width, length:width ratios and area of the features decreased in size when exposed to the chemicals. The Lowest Observed Effect Concentration (LOEC) values were 2000mg/L for Na₂SO₄, 3000mg/L for NaCl and 0.31mg/L for CdCl₂. The No Observed Effect Concentration (NOEC) values were 1000mg/L for Na₂SO₄, 2000mg/L for NaCl and <0.31mg/L for CdCl₂. Further research on the teratogenic effects of single chemicals and industrial effluent on developing C. nilotica embryos needs to be undertaken in order to evaluate the described test protocol for use in water resource management.

- Description: If manufacturing organisations are to improve their competitive positions in the global arena and increase profitability, their operations strategies need to be focused on: reducing cost, improving quality, increasing efficiency, improving the speed of delivery, developing and improving process flexibility, and ensuring that higher service levels are achieved and maintained. One of the critical success factors in implementing these strategies, within manufacturing organisations, is the relationship that exists between the maintenance and production functions. There is sufficient evidence to suggest that in many manufacturing organisations, the relationship that exists between these two functions is usually one of conflict, which if left unmanaged or unresolved has the potential to severely hamper effectiveness, productivity, creativity, and profitability of the organisation. The overall purpose of this research was to identify the interventions that manufacturing organisations can pursue, to effectively manage and resolve the conflict between the production and maintenance functions, in order to improve their competitive position in the global economy. The study was conducted in one particular manufacturing organisation in Port Elizabeth in the Eastern Cape. A research questionnaire was used as a means for collecting empirical data. The research questionnaire included various instruments used by previous conflict researchers, to identify and analyse the following dimensions of conflict within the organisation: conflict management styles used, the types of conflict perceived, and the amount of conflict perceived. The questionnaire was also designed to identify the sources of conflict, collect demographic information, identify issues relating to diversity, and indicate the respondents’ preferences to various organisational reporting structures. The results of the survey revealed key findings, which enabled the researcher to draw meaningful conclusions, and make recommendations as to how organisations can effectively manage and resolve the conflict that exists between maintenance and production functions.
