- Description: The African wildcat (Felis lybica cafra) is the most common and widely distributed of all wildcats. The southern Kalahari in South Africa offers favourable conditions for African wildcats and supports high wildcat densities on protected and unprotected land. African wildcats have been reported as livestock predators on South African farms, however wildcat-livestock predation is usually reported as infrequent and to have a low financial impact on the farmer. The aim of this study was, firstly, to determine what natural prey species were available for African wildcats on unprotected land and, secondly, to determine the extent of human-wildcat conflict on unprotected land in the southern Kalahari. The frequency of occurrence of potential African wildcat prey was determined through small mammal trapping, camera trap surveys and direct observations. The results indicated that a variety of the African wildcat’s natural prey species occurred on unprotected land and that the dune and adjacent ‘street' habitats most likely supported the majority of small mammals which are preferred prey for African wildcats. The African wildcat’s human-predator conflict status was determined through interview questionnaires (n = 22) with participants who owned or managed farms in the southern Kalahari. African wildcats were perceived to occur on 100% of farms, to be common in the region, to be the top livestock predator on 68% of farms and to be responsible for 46% (n = 1542 newborn lambs) of all livestock deaths in 2020. African wildcats were, however, not viewed in the same negative light as black-backed jackals (Canis mesomelas) and caracals (Caracal caracal), who received more negativity from participants and who had the highest persecution rates in my study area. This result could potentially be explained by a combination of generationally taught hatred towards certain species and due to the perceived livestock loss (e.g. livestock size and species) caused by each predator species. It is important to research and monitor wildcats outside protected areas to obtain a deeper knowledge of wildcat behaviour, abundance, population dynamics and other aspects of their ecology. By doing this, specific conservation and management questions can be addressed and through the knowledge of the natural history of a species, conservation failures can be avoided. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2021

- Description: As detections of gravitational waves (GWs) mount, the need to investigate various effects on the propagation of these waves from the time of emission until detection also grows. We investigate how a thin low density dust shell surrounding a gravitational wave source affects the propagation of GWs. The Bondi-Sachs (BS) formalism for the Einstein equations is used for the problem of a gravitational wave (GW) source surrounded by a spherical dust shell. Using linearised perturbation theory, we and the geometry of the regions exterior to, interior to and within the shell. We and that the dust shell causes the gravitational wave to be modified both in magnitude and phase, but without any energy being transferred to or from the dust. This finding is novel. In the context of cosmology, apart from the gravitational redshift, the effects are too small to be measurable; but the effect would be measurable if a GW event were to occur with a source surrounded by a massive shell and with the radius of the shell and the wavelength of the GWs of the same order. We extended our investigation to astrophysical scenarios such as binary black hole (BBH) mergers, binary neutron star (BNS) mergers, and core collapse supernovae (CCSNe). In these scenarios, instead of a monochromatic GW source, as we used in our initial investigation, we consider burst-like GW sources. The thin density shell approach is modified to include thick shells by considering concentric thin shells and integrating. Solutions are then found for these burst-like GW sources using Fourier transforms. We show that GW echoes that are claimed to be present in the Laser Interferometer Gravitational-Wave Observatory (LIGO) data of certain events, could not have been caused by a matter shell. We do and, however, that matter shells surrounding BBH mergers, BNS mergers, and CCSNe could make modifications of order a few percent to a GW signal. These modifications are expected to be measurable in GW data with current detectors if the event is close enough and at a detectable frequency; or in future detectors with increased frequency range and amplitude sensitivity. Substantial use is made of computer algebra in these investigations. In setting the scene for our investigations, we trace the evolution of general relativity (GR) from Einstein's postulation in 1915 to vindication of his theory with the confirmation of the existence of GWs a century later. We discuss the implications of our results to current and future considerations. Calculations of GWs, both analytical and numerical, have normally assumed their propagation from source to a detector on Earth in a vacuum spacetime, and so discounted the effect of intervening matter. As we enter an era of precision GW measurements, it becomes important to quantify any effects due to propagation of GWs through a non-vacuum spacetime Observational confirmation of the modification effect that we and in astrophysical scenarios involving black holes (BHs), neutron stars (NSs) and CCSNe, would also enhance our understanding of the details of the physics of these bodies. , Thesis (PhD) -- Faculty of Science, Mathematics (Pure and Applied), 2021

- Description: Wiener index is defined as the sum of the distances between all unordered pairs of vertices in a graph. The study of the Wiener index is motivated by its application in chemistry. This thesis focuses on finding extremal bicyclic graphs relative to Wiener index under various conditions such as fixed circumference (length of the longest cycle) or fixed size of the core (maximal subgraph with no degree less than 2). A segment of a graph G is either a path whose end vertices have degree 1 or at least 3 in G and all the internal vertices have degree 2 in G, or a cycle where all the vertices have degree 2 in G except possibly one. The lengths of all the segments of G form it segment sequence. We also discuss extremal graphs with given segment sequence. , Thesis (MSc) -- Faculty of Science, Mathematics, 2021

- Description: Absenteeism from school among girls due to a lack of menstrual health management (MHM) products has increasingly attracted attention from researchers and activists in recent years. Having highlighted the challenges caused by a lack of MHM products, the focus has been on the available facilities at schools to ensure MHM. Many schools in South Africa lack water, sanitation and hygiene (WASH) to ensure hygiene standards for the removal of bodily excre-ment, which further causes distress to girls needing MHM while at school. To investigate fur-ther the MHM challenges girls face, apart from access to products and WASH, this qualita-tive study purposively selected an all-girls’ school with access to good sanitation facilities. This research uses Foucauldian Discourse Analysis and Feminist Theory to explore the forms of discipline and control that girls experience at school to contain their bodily functioning and fluids, and the forms of resistance and support that girls encounter with MHM at school. I will argue that the ambivalent meanings girls acquire about menstruation at home and in soci-ety persist at school despite their own views that menstruation is normal. While MHM prod-ucts and WASH facilities need to be freely available, the problematic social response to men-struation is what needs to be addressed in order to emancipate women from the social patriar-chal power that informs their understanding that menstruation is shameful. MHM cannot only encompass products and facilities but needs to encompass a change in societal views of sex-ual and reproductive health. , Thesis (MA) -- Faculty of Humanities, Psychology, 2021

- Description: Using a social constructivist approach, within the social action model of community psychology, this research interrogates the features of successful community engagement partnerships that exist within the context of higher education. It draws on the co-management model that the Rhodes University Community Engagement (RUCE) division proposes, where partnerships are seen to be mutually beneficial. This research further interrogates whether the principles of community engagement that RUCE propose play out in reality, and whether systems of power are deconstructed, in working towards more equitable engagements. Drawing on the Early Childhood Development (ECD) Residence Programme for case studies, this research used a reflective multiple case study design in attempting to answer the research question. Four partner groups (i.e., 4 community partners and 4 community engagement representatives) were selected for this research. Each participant was interviewed twice (with a 6-month time gap) and also participated in two focus group discussions. Thematic analysis was used to analyse the findings. In taking a social justice approach, it can be argued that RUCE has made strides towards forming collaborative partnerships based on the ethics of ubuntu and aspects of transformative learning, which may lead to the decolonisation of higher education. However, critical engagement with the research findings suggests that in many cases the principles that RUCE propose are aspirational. More work needs to be done with both students and community partners to develop the kinds of partnerships that RUCE aspires to. This research provides valuable insight into how carefully managed community engagement partnerships in higher education have the potential to contribute to the transformation agenda of higher education institutions, while promoting equitable societies. , Thesis (PhD) -- Faculty of Humanities, Psychology, 2022

- Description: My thesis is a collection of prose pieces in the form of short stories, flash fiction and prose poetry drawing on memory and lived experiences to explore the trauma of death, grief and displacement, solace and the paroxysms of home. As a young woman from an Indian South Africa community, Hindu superstitions and folktales are my second skin, and shape both my worldview and my writing. I am inspired by Lidia Yuknavitch’s observation that, “all artists see things that are not there”, and by Dambudzo Marechera’s belief that, “Beneath reality, there is always fantasy: the writer’s task is to reveal it, to open it out, to feel it, to experience it.” In my stories about trauma and grief, I often distort the line between seen and unseen worlds, where, for example, hauntings are taken seriously as lived experiences. I have also been influenced by Han Kang’s The White Book, Kali Fajardo-Anstine’s Sabrina & Corina, and Sandra Cisneros’ The House on Mango Street. Read together, Kang’s stand-alone short stories form part of a greater collective ‘memory’ or ‘life’; Fajardo-Anstine’s collection illustrates how to write about a specific female Latina community while still telling individual stories; and Cisneros’ fragments of memories tell the story of a person’s life in narratives which are as long or short as they need to be. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

- Description: The role of healthcare workers (HCWs) is to render services to the sick. While executing their duties, these HCWs can fall ill due to various occupational exposures. HCWs are exposed to a range of hazards including physical, biological, chemical and ergonomic hazards. These hazards can cause physical injuries, diseases, mental strain and other adverse health effects.: The aim of this study was to assess the prevalence of occupational hazards amongst HCWs in urban and rural areas of the KwaZulu-Natal province, South Africa: A descriptive cross-sectional research design was utilised on the estimated sample size of 270 respondents, from ten public hospitals. The sampling method used to identify participants was convenience sampling and data was collected through a self-administered, semi-structured questionnaire. The analysed data was presented in descriptive and inferential summary statistics. The data was analysed using graphical and numerical descriptive statistics as well as inferential statistical techniques. The statistical significance was set at P0.05. The results revealed that both urban and rural HCWs were exposed to physical, biological, chemical and ergonomic hazards. Overall, physical hazards were the most frequently reported form of hazard exposure at 98,6%, followed by biological hazards (96,7%), ergonomic hazards (94,4%) and chemical hazards (23,7%). The duration of exposure to hazards varied from 12 months to 5 years. In a period of 12 months, radiation, cold, heat, slips and trips were the most common sources of physical hazard exposure while direct contact with patient bodily fluids was the most common source of biological hazard exposure and mercury was the most common source of chemical hazard exposure. More than a quarter of the HCWs had experienced some form of assault by a patient in the preceding 12 months. Over a three-year period, both urban and rural area HCWs reported the use of post-exposure prophylaxis and experienced symptoms of chemical exposure at work. Less than 6% of the HCWs had developed an occupational disease in the previous five years. There were no statistically significant differences in total exposure to hazards between urban and rural area HCW. , Thesis (Mtech) --Faculty of Health Sciences, School of Behavioural Sciences, 2021

- Description: Visualisation in the mathematics classroom has its own pedagogical value and plays a significant role in developing mathematical intuition, thought and ideas. Dynamic visualisation possibilities of current digital technologies afford new ways of teaching and learning mathematics. The freely available GeoGebra software package is highly interactive and makes use of powerful features to create objects that are dynamic, and which can be moved around on the computer screen for mathematical exploration. This research study was conceptualised within the GeoGebra Literacy Initiative Project (GLIP) – an ICT teacher development project in Mthatha in the Eastern Cape, South Africa. The focus of this study was on how GeoGebra could be used as a teaching tool by harnessing its powerful visualisation capacity. In the study, selected GLIP teachers collaboratively developed GeoGebra applets, then implemented and evaluated them. The research methodology took the form of action research cycles in which the design, implementation and evaluation of successive applets determined the data gathering and analysis process. My data consisted mainly of recorded observations and reflective interviews. The underlying theoretical foundation of this study lies in constructivism, which aligned well with the conceptual and analytical framework of Kilpatrick et al.’s (2001) description of teaching proficiency. An in-depth analysis of my classroom observations resulted in multiple narratives that illuminated how teachers harnessed the visualisation capabilities inherent in the software. My findings showed that dynamic visualisation and interactivity afforded by the use of technology are key enabling factors for teachers to enhance the visualisation of mathematical concepts. My analysis across participants also showed that technical difficulties often compromised the use of technology in the teaching of mathematics. The significance of this research is its contribution to the ongoing deliberations of visualisation and utilisation of technological resources, particularly through the empowerment of a community of teachers. The findings recognised that the integration of technology required appropriate training, proper planning and continuous support and resources for the teaching of mathematics. This action research provided insightful information on integrating Dynamic Geometry Software (DGS) tools in mathematics classrooms that could be useful to teachers and curriculum planners. , Thesis (PhD) -- Education, Education, 2021

With many species making up the diverse ecosystem the question remains, how do they survive with less than 200 mm of rainfall per year? (Lovegrove 1993) Survival in harsh climatic conditions have been tried and conquered across the world, from desert to artic conditions. With a harsh climatic environment and barren conditions, where does one set up a place of gathering? With tourism being one of the main pillars of the economy in Namibia. On an already existing route along a perennial water source, a conference centre is set up as a midway point for meeting of tourists with a local flair (Humavindu, 2013 Through learning from this environment and environments similar to these, the final product of this treatise results in a place of meeting along this string of settlements along the river, through means of bio-inspired design and phenomenological theories of place making. The challenge of nature vs building is questioned.

- Description: Statutory wage setting and the extension of labour laws to the South African agrarian labour market are path-breaking events that altered the unilateral power which agrarian employers had, under apartheid, to set low wages and harsh employment conditions. Yet, economic sociologists have shown little interest in the agrarian minimum wage in South Africa. Consequently, little to no sociological perspectives are available on the way in which statutory wages shape the setting of actual agrarian wages, employment conditions, labour relations and working and living conditions. At the same time, economic sociology’s neglect of agrarian minimum wages perpetuates the dominance of economics in minimum wage research, as well as the narrow cost-benefit analysis, and firm and employer-centric focus, deployed by both opponents of minimum wages in the neoclassical economics camp and supporters in the heterodox economics camp. The firm-centric focus also applies to the few labour relations scholars who focus on minimum wages. As a result, a wide body of empirical information is available and concentrated in the Global North, on low-waged, urban-based firms’ employment and labour relations strategies with the occasioning of minimum wage laws, with scant to non-existing information on rural-based workers’ experiences in the Global South, at least in the case of South Africa. This thesis addresses the lacuna in existing research, specifically by concentrating on agrarian workers’ narratives of the outcomes of minimum wages on actual wages and conditions, and experiences at the site of production and in the sphere of expanded social reproduction. The conceptual framework of the thesis is rooted in a critical realist meta-theory which directs inquiry towards the search for underlying causes of events with a sensitivity to the interaction of structure and agency, so as to develop explanations of events, which in turn encourage emancipatory thought and praxis. Within this framework, a political economy perspective of the agrarian minimum wage is charted, founded on an inter-disciplinary approach that incorporates economic sociology perspectives, which view markets as socio-political constructs, alongside a Marxist analysis of wages and the distinction between the value of labour and the value of labour power. Also relevant are segmentation labour market models where the focus is on segmentation in labour supply, demand and regulation, and institutional economics that highlights labour’s weak bargaining power in low-waged labour markets. Based on this analytical perspective, the South African agrarian minimum wage is seen as a necessary intervention stemming from post-apartheid uneven neoliberal restructuring processes, to address extremely low agrarian wages that pose threats to the ongoing generation of agrarian labour power. Low agrarian wages are located in unequal power relations in the workplace and are embedded in the totality of the low-waged agrarian labour market, composed of particular features in the supply-side of the labour market (the sphere of social reproduction of labour), the demand-side of the labour market (the site of production), and the forces of regulation (the labour relations regime). The thesis explores new ways of conceptualising minimum wages in the South African context, placing emphasis on the local agrarian labour market, and it highlights the agency of agrarian labour by revealing their struggles, working life and living conditions. In so doing, the research expands inquiry beyond economic “impact” at the level of the firm/employer to examine: (a) workers’ employment trends before and after the minimum wage was introduced, (b) the extent of changes in working and living conditions and labour relations, (c) the scope for workers in animating changes and their struggles and challenges, and (d) shifts in actual wages in relation to prescribed wage rates. Focussing on the aforementioned aspects represents an attempt in this thesis to build on themes, raised in heterodox economics studies, of minimum wages and their relationship to the social devaluation of low-waged work, inequalities in bargaining power, and justice. Based on a stratified sample of workers that included, among other variables, sex, geographical area and agricultural sub-sectors, original data was collected through 52 in-depth interviews, two focus group interviews (comprised of 10 workers), and 501 surveyed workers. The research did not find widespread job losses when minimum wages were introduced, as per neoclassical economics’ predictions. Nor did it find transitions from low- to high-road approaches in employment strategies and labour relations, as claimed by certain heterodox economists. Instead, the findings at the sites of production corroborate the uneven, mixed and contradictory findings of applied heterodox minimum wage studies on employment strategies, labour relations and wage settings. In this light, it is concluded that the agrarian minimum wage had layered outcomes for workers based on key findings, which include: (a) the minimum wage became the maximum wage as actual wages increased and clustered at the prescribed wage rate; (b) a level of gender wage parity close to the level of the prevailing prescribed minimum wage was found, but an overall gendered pattern to low-waged employment surfaced and manifested differently at sub-sector and enterprise levels; (c) though no changes were found in the way work was organised and how workers executed their tasks alongside no fundamental changes in the social relations of production, statutory minimum wages and limitations on working hours did reduce the hours of work and the existence of unpaid overtime work in certain sub-sectors such as livestock and dairy workplaces, through worker and employer initiatives (yet, at the same time, work intensification in compressed working hours appeared in the sample in other worksites, for example citrus workplaces); (d) authoritarian labour relations existed in varying depths and forms, based on sub-sector and enterprise characteristics, which shaped the propensity and scope for worker action; and (e) the layered outcomes of the agrarian minimum wage were felt at the site of social reproduction, where it brought a measure of relief for sampled workers; however, it was chronically inadequate to allow workers to meet their subsistence needs comprehensively. The research findings also highlight sub-sectoral complexities in changing employment and labour relations strategies from low- to high-road approaches in the agrarian sector. The layered outcomes of minimum wages for agrarian workers stems from the combined and uneven amalgamation of pre-existing and new conditions and relations consequent to neoliberalising processes in the agrarian political economy as well as the low minimum wage-setting. The thesis thus argues that the mixed outcomes reflect the layered character of the minimum wage as a conversion factor, which in turn equates to a layered notion of justice. This is because, on the one hand, the minimum wage ameliorates the plight of agrarian labour but, on the other hand, and given the bulwark of authoritarianism, pre-existing conditions and neoliberalising processes, the collective vulnerabilities in the agrarian labour market have expanded and may be intensifying. The agrarian minimum wage acts as a double-edged sword in contexts of mixed and layered outcomes for agrarian labour. A layered perspective of the conversion factor of a minimum wage exposes the possibilities and limitations of statutory wages as a conversion factor, based on context, and identifies the limits and possibilities for worker mobilisation and action. In the case of this research, the agrarian minimum wage deals in limited fashion with the value of labour power because of the initial and subsequent low settings; the minimum wage does not deal with class exploitation and the value of labour, although it sets the frame for instigating basic labour standards. The implications of a layered conversion potential of low minimum wage-settings are profound for conceptualising, theorising and researching the link between statutory wages and justice, with respect to the value of labour power and the value of labour. Future research on the minimum wage based on a Marxist reading of wages and located in real labour markets, strengthens heterodox approaches by deepening theories on the relationship between statutory wages, justice and production. , Thesis (PhD) -- Faculty of Humanities, Department of Sociology, 2021

- Description: Work gratification and expectancies are of the utmost importance to the skilled workforce in the South African construction industry. The price paid for a demotivated workforce in this industry is very high and it leads to friction in the workplace, displeasing work outcomes and time delays. Furthermore it leads to increased incidences of theft,absenteeism and outputs that arebelow standard in terms of productivityand thequality of the work.In order to motivate the workforce in the construction industry,a day-by-day, step-by-step,hands-on approachmust be used. The aforesaid aids site managers to manage effectively and this in turn leads to an increase in production by way of enhanced productivity. Research shows that a correlationbetweenmotivation, excelling at work, improved productivity and fulfilment and expectancyexist. The reason why individuals act in a specific manner and choose not to act in a certain way can be directly linked totheirmotivation and engagement.As a member ofthe construction industry in South Africa, Stefanutti Stocks isseen as one of the leading construction groups. Employing more than 12 000 workers it has the ability to provide a wide variety of different scale projects for a host of clients in varied markets. The division concentrated on in this study is the Roads, Pipelines and Mining Services (RPM)Business Unit. The MD of the RPM Business Unit when starting at the company a few years ago came to the conclusion that in order for the RPM Business Unit to function optimally certain business inconsistencies regarding employee engagement needed to be addressed. Based on this he decided to use a consulting firm, AIM,to establish what the exact concernswere and what interventions wererequired to deal with them. ivInterventions facilitatedby AIM includedManagement Training Programmes and Workshops as well as one-on-one coaching sessions with selected individuals.The methodology used in this study was to measurethe current level of employee engagement subsequent toengagement interventionsconcludedby AIM.The approach used was the use of surveys distributed through AIM in conjunction with the RPM Business Unit’sHR Department. The surveys were distributed via Survey Monkey Software owned by the RPM Business Unit of Stefanutti Stocks. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMMU Business School, 2021

- Description: South African Ports have made a commendable effort in improving productivity through technology and they compete reasonably well with ports in other developing countries. However, sufficient research about the factors that affect the adoption of smart ports and associated benefits have not been adequately explored in South Africa and in other developing countries. The consequence is that ports are faced with high levels of inefficiency, deteriorating logistical performance, poor port productivity, high transport costs and truck congestion. Therefore, the study focuses on determining and evaluating factors that affect the adoption of the smart port’s concept in developing countries in order to improve port productivity and efficiency. A proposed conceptual Smart Port model was developed based on an in-depth review of literature on smart ports, covering both national and international research. The study follows a quantitative research approach and is based on positivism. The sampling frame of the study was limited to 1,350 employees and managers in South African ports. The data was collected from South African port’s employees via an email survey, using an embedded questionnaire. The data collected from a total number of 197 participants were analysed statistically. The confirmed model for smart ports in developing countries shows statistically and practically that a smart port is dependent on operations technology, environmental management, energy consumption, safety and security, integration, infrastructure and equipment and a skilled workforce. One of the key study learnings from the study is that ports should adopt the smart port targeted initiatives in order to transition into smart ports. The developed Smart Port model can be used as a broad guideline to inform ports in South Africa and in other developing countries about the fundamental elements of an ideal port in order to improve their efficiency, competitiveness and to stimulate their growth and profitability. The study is viewed as a success in that it provides the port industry in both developed and developing countries with a deliberate and clearly defined Smart Port model structure, which did not exist before. A follow-on longitudinal study to determine the impact of the changing technologies on the smart ports is recommended among others as a future research opportunity. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: A narrative study of students’ and staff’s experiences of living with HIV and AIDS at Rhodes University Research on HIV and AIDS in university settings, especially research exploring the experience of living with the disease, has been minimal. As a response to the knowledge and research gaps, this thesis is a qualitative study involving students and staff living with HIV (LWH) and accessing treatment (ART) at the Rhodes University Health Care Centre. This study explored the personal and social symbolisms as well as meanings attached to living with HIV, through in-depth interviews with ten students and staff living with HIV, all purposively sampled and recruited through the Rhodes University Health Care Centre. Using social constructionism, symbolic interactionism and the theory of biographical disruption, the narratives revealed a positive and inspirational side of living with HIV and AIDS – especially emphasizing that PLWHA do not have to surrender to the deadly narrative of the disease. It became evident that stigma, both internal and external, largely influences illness narratives. Furthermore, the study revealed the social reconstruction of life narratives both in order to understand the illness in terms of past social experiences and to reaffirm the impression that life has a course and the self has a purpose. All participants found that accessing treatment from the Rhodes University Health Care Centre positively influenced their experiences of adherence and reconstruction of narratives. The study indicates that HIV-related interventions in place at the university need to pay more attention to the psychosocial needs of PLWH, involvement of PWLH, as well as keeping up with the continuously changing global HIV narrative. The study argues for more attention to in-depth experiences and personal narratives in HIV and AIDS, and PLWHA education at Rhodes University. , Thesis (PhD) -- Humanities, Department of Sociology, 2021

- Description: A lack of effective communication has often resulted in information bottlenecks and conflicts in the execution of construction projects and is the primary cause of problems such as delays, increased project cost, reduced roductivity, loss of profit, or damaged professional or business relationships within the construction Industry. Despite all the advancement in the communication and integration tools in a drive to optimize the construction industry, this challenge still remains. In order to address this problem, this research project sought to determine the key elements that constitute effective communication and its importance to the successful projects delivery within the construction industry. A survey design which involved a sample study of a representative population through the use of a questionnaire was used. The research population comprised of all design consultants. The research found that, Common tools and processes, Good change management, PM best practices & Performance KPIs and resources are the main missing elements respectively for effective communication, which foster the conflicts inherent within the industry. The following key factors are however mostly present in project team; well-articulated project scope, quality information exchange and commendable people, cultures and behaviour. Informational asymmetries, misrepresentation, poor PM skills hinders effective communication and often results in project failure. There is therefore need to concertize the design professionals on the importance of effective communication and enlighten them on the dynamics involved. The construction industry is inherently complex, multi-disciplinary, fragmented, sporadic, dynamic and generally resistant to change. Hence, the need for rigorous research and feed back to the design professionals on effective communication especially during the changing times driven by technology, dubbed the 4th revolution. More work is to be done in order to achieve the effective communication, in the following study research area for the construction industry; the alignment of tools and processes, change management and Performance KPIs for the construction industry. These factors present a huge challenge in a fragmented and adversarial industry which is inherently resistant to change. , Thesis (MSc) -- Faculty of Engineering,the Built Environment and Information technology,2021

- Description: Pipelines for calibration and imaging of radio interferometric data produce many intermediate images and other data products (gain tables, etc.) These often contain valuable information about the quality of the data and the calibration, and can provide the user with valuable insights, if only visualised in the right way. However, the deluge of data that we’re experiencing with modern instruments means that most of these products are never looked at, and only the final images and data products are examined. Furthermore, the variety of imaging algorithms currently available, and the range of their options, means that very different results can be produced from the same set of original data. Proper understanding of this requires a systematic comparison that can be carried out both by individual users locally, and by the community globally. We address both problems by developing a systematic visualisation framework based around Jupyter notebooks, enriched with interactive plots based on the Bokeh and Datashader visualisation libraries. , Thesis (MSc) -- Faculty of Science, Department of Physics and Electronics, 2021

- Description: The study investigated access to digitised archival collections in two selected institutions in the Eastern Cape Province, South Africa. This study is significant because it sought to generate insights on adaptability of technology in archives and library operations, and accessibility thereof. This is important for monitoring the accessibility of digitised archival collections at institutions to improve their operations and maximize the global visibility. This study adopted qualitative research methodology. The researcher followed a rigorous methodological path that began with a thorough literature review and the careful and thoughtful posing of research questions and objectives. A purposive sample was chosen from National Heritage and Cultural Studies Centre (NAHECS) and International library of African Music (ILAM) (staff members) and interviewed through face-to-face interviews. The collected data was analysed thematically. The study established that, the type of materials digitised at NAHECS and ILAM are bound books, fragile papers, photographic prints, slides, audio-visual materials,artefacts and documents such as personal letters of early travellers,missionary’s records,traders writing personal file and political parties documents. Secondly, the study established that end users of digitised materials are researchers, students, archivist, librarians, international and local community, composers, musicians, and historians. It also emerged that awareness programmes used to increase public knowledge about access to digitised content in the two study sites include conferences, social media, and television advertisements. However, there are challenges faced in providing access to digitised materials at NAHECS and ILAM. Some of these challenges include lack of funding, unavailability of resources, lack of awareness, and information insecurity. These challenges have made access to digitised archival materials difficult. Based on these findings, it is recommended that archives facilities should be well resourced and archivists be continually trained on access to digitised archival materials. , Thesis (M Bibl) -- Faculty of Social Sciences and Humanities, 2021

- Description: The overarching objective of this thesis is to undertake a critical examination of the institutional accountability policy and practice of the Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund) in the context of its partnership programme in Ghana. The Global Fund is a global public-private partnership (GPPP) in health engaged in public health policy processes worldwide. As a GPPP, the policy mandate that underpins its global response to fight the aforementioned diseases requires it to enter into partnerships with recipient countries to finance their national health policy responses and strategies to tackle these diseases. Situating accountability within the context of the shift from an international health to a global health regime, the study argues that the emergence of GPPPs in health and the formal policy mandate and decision-making powers they exercise have had knock-on consequences for understanding accountability in the global health regime. This is because while the understanding of accountability for public health policy processes in the international health regime revolved solely around state-based and state-led accountability processes, it is no longer so in current global health regime. Since these GPPPs are not states, they derive their understanding of accountability from the nature and character of their individual policy and practice arrangements. However, despite contestation around the Global Fund’s accountability in global health literature, this literature has little to say on the question of how the Global Fund itself (as a partnership organisation) understands accountability in policy and how this understanding informs its practice in specific settings of global health. Thus, this study contributes to literature on GPPPs’ accountability in global health by specifically exploring how the Global Fund understands accountability in policy and how this understanding informs its accountability in practice, in particular in relationship to its implications for country ownership of health policy in Ghana. Drawing on fieldwork undertaken in Ghana, and guided by a critical political economy approach, this study will demonstrate how: 1) the Global Fund’s institutional policy and practice arrangements undermine accountability to the government and to those affected by their activities; 2) the Global Fund’s practice of country ownership is reflective of conditional ownership despite the fact that the Global Fund claims to promote country ownership as a core principle of its accountability practice in aid recipient countries; and 3) the accountability policy and practice instruments of the Global Fund are not politically neutral, but are rather a function of relations of power. To improve the ability of Ghana (and other recipient countries) to own their developmental policies, a reordering of global economic relations is needed, with a renewed emphasis and focus on economic justice and human rights. Such a reordering will improve the material capabilities (control of and access to global centres of production, finance and technology) of aid recipient countries. This will empower Ghana (and other recipient countries) to play a more dominant, rather than a subsidiary role in how the global health landscape is organised and financed and in policy processes undertaken by global health policy institutions like the Global Fund. In this way, Ghana (and other developing countries) will be able to limit and mitigate the dominance and influence of powerful donors who shape the institutional policy and practice arrangements of global health policy institutions like the Global Fund. , Thesis (PhD) -- Faculty of Humanities, Department of Political and International Studies, 2021
