- Description: The thesis presents a framework to integrate social entrepreneurship (SE) into development planning in South Africa. Even though there is no consensus on a universally accepted definition of the term, there is concurrence that SE brings about social change that can influence the overall development of the community. In South Africa, SE is thus conceived of as one of the mechanisms for addressing the wicked and persistent socio-economic challenges that face the country. Social entrepreneurship occurs in areas such as education, health, skills development, youth programmes, rehabilitation, safety, food security, poverty, job creation, human rights activism, environmental issues, arts and culture, among others. However, it remains unclear how SE is integrated into the development planning and implementation processes. Questions of integrating SE into development planning are asked within the context of South Africa as a democratic developmental state that intervenes in the development process. It emphasises the mobilization of and engagement with all sectors towards the achievement of its development objectives as articulated in the national development plan (NDP). Also, government recognizes organizations in the social enterprise sector (such as NPOs and NPCs) as stakeholders and development partners who deliver relevant services towards the achievement of these development objectives. However, there is a lack of framework to mobilize and integrate the social enterprise sector and SE into the development planning process. Social entrepreneurship, therefore, tends to occur in insolation from other development programmes. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 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: The manufacturing sector, globally, is facing significant challenges due to current societal, economic, environmental, and technological developments. To overcome the challenges into the future, manufacturing organisations will need new capabilities to manage their end to end supply chains to make sure that it is responsive and agile. The Smart factories, as an element of Industry 4.0, drive efficient operations while at the same time ensure that employees are safe, and operations are environmentally sustainable. The ability to be flexible, to be reconfigured and to be connected to customers allows Smart factories to mass customise their customers’ orders and maintain the same efficiencies when compared to mass production operations. Technologies such as the Internet of Things (IoT) in Smart factories must be employed to further drive efficiencies, agility and ease of production by giving operations the capability to respond in real time to problems with machines and customer requests. Smart factory technology allows operational sustainability through the efficient use of resources. The Smart factory revolution is significantly changing the relationship between humans and machines. Based on the literature review conducted, a theoretical model was constructed which was tested at a Consumer Health Organisation to identify the relationship between the dependent and independent factors. The independent factors, specified in the model were job security, organisation culture, training and skills, trust, costs and resources, parent company and standards. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU 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: In South Africa, substance abuse and sexual assault and/or abuse are major concerns. Society has become desensitised to these topics because of its high prevalence rate. Substance abuse is often greeted with stereotypes and prejudices that view individuals as a problem to society. The proposed research employed a qualitative, exploratory, and descriptive strategy of inquiry, guided by narrative biographical research design. Social constructionism was employed as a theoretical framework to explore how an individual had constructed her life story, with a specific focus on her experience of sexual trauma and subsequent substance abuse. A non-probability purposive sampling method was used to recruit a research participant who was in the public domain as a motivational speaker in an attempt to guard against retraumatisation. Two data collection methods were employed, namely one-on-one semi-structured interviews and an invitation to the participant to journal about her experience, guided by specific stimulus questions. Thematic narrative analysis was employed as a method of data analysis. The outcome of the investigation had provided a narrative account of the research question at hand with the following themes coming to the forefront:- Early childhood experiences ( pre-sexual abuse), sexual trauma, recovery and meaning making. , Thesis (MA) -- Faculty of Health Sciences, 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: Through the lens of Foucauldian genealogy, this thesis problematises the subject positions towards Afrikaner identity reflected in contemporary Afrikaans songs covered by Huisgenoot magazine. Such a genealogical exploration thematises the games of truth underpinning the formation of Huisgenoot, highlights its role in solidifying white Afrikaner Nationalist discourse of apartheid, observes its more populist, profit-oriented approach from the 1970s onwards and considers the residual echoing of its former discursive orientation. The song analysis of selected Afrikaans songs/music videos covered in Huisgenoot is guided by the semiotics of Nicholas Cook, such that it frames the analytical question of how such music is driven by conformance, contest and complementation between multi-media elements in ways that make meaning possible. Accordingly, this methodology resonates with the non-essentialising focus of Foucauldian problematisation, premised on critical resistance that makes new responses simultaneously possible. The self-reflexive autoethnographical approach employed, entailing the author’s dialogical engagement with her own ‘Afrikaner self’, similarly facilitates the dynamic interplay between multiplicities. Correlatively, on the one hand, more ‘closed’ and more ‘open’ Afrikaner identity positions reflected within the songs are analysed, as well as seemingly ‘reconciliatory’ / collaborative’ musical manifestations which ultimately revert back to more ‘closed’ identity constructs. But on the other hand, observation of adherence to a ‘white-black’ dichotomy within songs that manifest more ‘closed’ identity positions also leads to consideration of the parallels between the goals of white Afrikaner Nationalism and the current Decolonisation narrative, which is informed by Black Consciousness thought and generated by the ‘Colonisation of a Special Kind’ ANC policy. Both such Decolonisation rhetoric and the countering rhetoric of the Neo-Afrikaner Protest Movement (NAP) are thus identified as metanarratives, underpinned by a ‘white-black’ dichotomy. In this regard, while Huisgenoot’s predisposition towards songs manifesting more ‘closed’ Afrikaner identity positions is considered in terms of its aforementioned profit-oriented endeavour to appeal to its ostensible primary readership, an encouraging increase in coverage of coloured artists is both noted and occasionally seen to overlap with its coverage of songs manifesting more ‘open’ Afrikaner identity positions. Among the latter one may – again in Foucauldian terms – differentiate between songs focussed on an engagement in cross-cultural relations of power, and songs intent on shattering states of domination of power blocks, often through shocking juxtaposition of disparate elements. These more violently dismantling endeavours, it is argued, comprise examples of Foucauldian transversal struggles, although their coverage in Huisgenoot is also attributed to their shock value and/or record sales, rather than their transformational potential. Furthermore, such Huisgenoot coverage is also seen to place more transformationally oriented artists at risk of media ‘domestication’, with its concomitant inhibiting of creativity. Finally, the researcher’s commitment to creative problematisation of her own Afrikaner identity, coupled with acknowledgement of her inescapable textual entrapment, culminates in her acceptance of the continual flux characterising dialogical power relations, before she – in accordance with the Foucauldian methodology employed – presents all ‘conclusions’ in a non-dictatorial spirit of ‘truth creation’, desirous of continual self/other dialogue. , Thesis (PhD) -- Faculty of Humanities, 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: While climate change and rapid urbanisation are impacting our cities and existing infrastructure, population growth and resource scarcity are placing unprecedented pressure on our food systems. In light of such challenges and the Sustainable Development Goals, resilient solutions are being sought to move both urban development and food production towards a more sustainable future. In this context, Urban Agriculture (UA) has been identified as a possible mechanism to complement rural food production with many associated social, economic and environmental benefits for urban communities. Some of these benefits include increased food system resilience, better urban environmental management, circular and productive reuse of urban wastes, employment opportunities, reduced food miles and the promotion of social inclusivity. Through a sustainable food system lens and underpinned by Resilience Theory, this research study sets out to investigate and explore the considerations for UA development. The research study reviews UA literature to identify and analyse the common challenges which act as barriers to implementation, as well as the current or potential opportunities which could be leveraged to drive UA development. The insights gained from literature on UA and UA development frameworks; and the data gathered from qualitative interviews with experts working in UA-related fields in South Africa (SA), were used to build a conceptual framework for UA development in SA. The conceptual framework developed is intended to be used as a guide for local municipalities, urban planners, urban farmers, urban communities and UA support organisations in their approach to developing UA initiatives. The findings from this research study reveal that UA development in SA involves numerous actors at both provincial and municipal levels; and within private institutions, businesses, universities, farmer organisations and society. The findings also reveal that UA currently occurs at many levels in SA, with each level drawing a particular range of participants due to the various social, economic and/or environmental features of the initiative. Along with challenges associated with land access, the lack of UA-related knowledge, the threat of theft, vandalism and soil contamination (to name a few); a lack of understanding of how agriculture can fit into urban spaces was found to be a major obstacle. The findings suggest that this lack of understanding has led to an under-realisation of the full potential of UA in South African towns and cities; and an inability to incentivise and optimise the development of UA. Considering the findings derived from the investigation, the study proposes five major considerations for UA development in SA, all of which are unpacked in the conceptual framework. The study concludes by making recommendations for UA decision-makers and UA organisations to consider for future developments.

- Description: Charles Manson was notorious for his antisocial behaviour and influence; through his charisma, he formed a group of followers known as the Manson family. Manson and his followers became involved in various criminal activities which culminated in the murder of 7 people. These murders were not committed by Manson per say, but he planned them, and incited his followers to commit them; this resulted in a trial and Manson going to prison, being given a life sentence. He continued to influence people while he served his sentence in prison. Manson died of natural causes in November 2017. The research study explores and describes the life of Manson in the form of a psychobiography. The aim of the study was to gain insight into the personality development of Charles Manson. This was achieved by applying Otto Kernberg’s Object Relations Theory to Manson’s known life experiences. Various data was collected and triangulated, using primary and secondary sources. Miles, Huberman, and Saldana’s (2013) three step procedure was used to analyse the data. The findings highlight the influence of genetics and rejection as pivotal to the unfolding of Manson’s personality, and provide insight into how his antisocial patterns unfolded. They highlight, in particular, his use of control, dominance and devaluation to protect his positive experience of self. , Thesis (MA) -- Faculty of Health Sciences, Department of Psychology, 2021

- Description: Gavin Maxwell was an author and naturalist. He published a memoir called A Ring of Bright Water, which shaped the way millions of readers viewed nature. Maxwell wrote simple prose which paints an idyllic and moving picture of his time spent in his “lost paradise”, alongside his beloved animals, most notably his otters. However, in reality Maxwell was a man in conflict, seen in volatile relationships, financial recklessness, and the preference for the company of animals over people. The aim of this study was to explore Maxwell’s life to gain insight into his personality development. This was achieved by applying Otto Kernberg’s Object Relations Theory to his life experiences. In doing so the author hoped to gain an understanding of the personality dynamics that led to Maxwell’s relational difficulties and eccentricities. Data was collected by triangulating multiple sources of information on his life. Miles and Huberman’s (1994) three step approach was used to analyse data collected. These steps are: data reduction, data display, and conclusion drawing and verification. The research study found that Maxwell’s personality development was likely arrested at the third stage of Kernberg’s model. Maxwell relied primarily on immature defence mechanisms based in splitting and possessed a fragile ego structure which he protected through grandiosity. The findings indicated that Maxwell’s personality falls in the borderline level of functioning with a strong likelihood of pathological narcissism. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: The aim of the study was to explore and describe Harvey Milk’s identity development and performance from the theoretical perspective of Narrative Therapy. Harvey (1930-1978), was an American Gay Rights activist who became one of the first openly gay political candidates to be elected to public office in the United States in 1977, before being assassinated in 1978. The study was conducted within a postmodern Social Constructionist epistemology which applied Michael White and David Epston’s (1990) Narrative Therapy as a particular theoretical lens to understand Harvey’s lived experiences. Harvey was chosen as the research subject based on his ability to construct his public identity as an openly gay politician and activist in defiance of the contemporarily dominant heteronormative discourse, despite the danger this posed to his personal safety. His selection was made through purposive sampling which facilitated a qualitative, single case psychobiographical study. Data on Harvey was obtained from both primary and secondary sources available in the public domain, and was analysed using Narrative Therapy concepts that describe individual identity. The study’s findings detail the narrative processes Harvey underwent and the discursive influences he experienced to move from being a closeted gay man, who hid his sexuality from public view, to an openly gay trailblazing Gay Rights activist, who fiercely challenged the norms and effects of heteronormativity on both his own life and that of his gay community. The study emphasises the value of psychobiography and Narrative Therapy to understand individual identity construction and performance. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: The researcher conducted a sociological investigation into the persistence of child labour in the fishing communities of Uganda, specifically in the Ssese Islands, Kalangala District, on the Kisaba and Nakibanga landing sites situate in Bukasa. The study aimed at investigating the sociological aspects of persistent child labour practices in the fishing communities. The study employed a qualitative research method with a descriptive case study design, utilising an interpretive paradigm. The case study design facilitated the researcher’s investigation into child labour practices in their natural settings. The study employed mainly in-depth interviews, focus group discussions and observations for data collection. Data analysis was performed utilising the ATLAS.ti computer software package to identify the sociological factors involved with employing child labour. The Various themes emerged from the data analysis. The study established that despite the Ugandan Government domesticating all the UN/ILO Conventions on Rights of a Child and Worst Forms of Child Labour, the OAU Charter on Child Rights and Welfare and also instituting legal frameworks at national level, the practice of using child labour persists. The findings disclosed that economic, sociological and structural factors appear to perpetuate child labour in the fishing communities. Economic factors such as poverty, unemployment or underemployment, then sociological aspects such as men abandoning their helpless families on landing sites as they follow the fish according to seasons. Furthermore, the community attitudes such as low value for education, child labour being a normal trend and part of apprenticeship for the children. Again, there are structural issues such as the inadequate implementation and the weak enforcement of the legal frameworks, including insufficient infrastructures such as schooling facilities. These factors appear to perpetuate child labour in the fishing communities. The study concluded that there is an urgent need to address the issues associated with the persistence of child labour in the fishing communities. The study recommends employing a holistic multipronged approach through bottom-up participatory planning and integrating stakeholders at various levels. This could enhance efforts and share ideas and resources that can result in effective operations in order to eliminate child labour in the fishing communities. , Thesis (DPhil) -- Faculty of Humanities, 2021

- Description: Our understanding of the evolution of dune morphology has been hampered by a lack of empirical observations of airflow behaviour over dune forms. Sand dunes intrude into the atmospheric boundary layer and convergence of streamlines results in an acceleration of airflow up the windward slopes of dunes. This study examines the airflow structure and corresponding bedform development on the windward slope of a 7 m high transverse dune on the edge of the Alexandria coastal dunefield, Algoa Bay, South Africa. The Alexandria dunefield is subjected to a trimodal wind regime, consisting of the dominant south-westerly which blows all year round, summer easterlies and winter northwesterlies. The morphology of the study dune, Dune13, is controlled by the easterlies and north-westerlies, and reverses seasonally with respect to these two winds. Seven section lines 30 m apart and normal to the dune crest were surveyed regularly over the period of a year to monitor the reversal process. Three detailed topographic surveys were also done during this period. Airflow behaviour was monitored during the year. Wind speed profiles on the windward slope of the dune were measured using 4 to 5 vertical arrays of anemometers positioned from the base of the dune to the crest on a 1 selected section line. Usually 4 to 5 anemometers were deployed in each vertical array, from a height of 6 to 10 cm above the surface, up to a height of 150 cm above the surface. Initially 8 microanemometers were available; ultimately 28 anemometers were run simultaneously. An independent weather station at an elevation of 6 m recorded the unaccelerated flow. Local gradient measurements and erosion and deposition rates were recorded along selected section lines. Strong summer easterly winds (14 m/sec at 1.4 m above the dune crest) were measured on a dune slope in the process of being transformed from a slipface to a stoss slope. The following winter, light north-westerly winds (typically B m/sec at 1.6 m above the dune crest) were measured on the new windward slope already reversed by the prevailing winter wind. Airflow data confirm the compression of airflow against the windward slope resulting in a non-logarithmic wind speed profile. Compression results in an increased shear velocity within 30 cm of the dune surface, and the dune slope is eroded. Higher up in the wind speed profile, shear velocity decreases to 0.1 m/sec. It is not known at what height the wind speed profile recovers from the intrusion of the dune into the boundary layer. High values of shear velocity (1.6 m/sec) above the rounded crestal area of the dune record the recovery of the wind speed profile from flow divergence, which is a response to the rapid reduction of dune gradient and is accompanied by deposition of sand in this region. 2 The erosion pin data act as a simple and sensitive test for changes in gradient, reflecting the dune's response to changes in the airflow regime. The shape of the dune plays a major role in determining the extent of the compression and the distribution of shear velocity up the slope. Increased shear velocity is experienced on that part of the slope which is nonaerodynamic with respect to the prevailing wind. Under unidirectional conditions, feedback between flow and form results ultimately in a slope with a curvature such that shear velocity increases systematically upslope. The survey data and erosion pin data record the reversal process as the dune achieves a new steady state during each wind season. The existence of a non-logarithmic wind speed profile makes it difficult to know what relevant measure of shear velocity is to be used in sand transport equations. Future work should include wind speed measurements within 10 cm of the surface. An ideal study modelling aeolian bedform development would utilise wind tunnel measurements, combined with field measurements such as obtained in this study, for comparison with numerical modelling. The study needs to be extended to 3-dimensional airflow measurements. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: This study is set out to apply mixed methods approach to a systematic review of research into working capital management in South Africa. Research into working capital management has primarily focused on the effect it has on a business’s profitability, liquidity and performance. There is, however, limited research on the topic working capital management in South Africa and, as such, the primary objective of this study is to review research outputs on working capital management in South Africa. The purpose is to identify research gaps in the current body of knowledge by means of the development of a recommendation’s framework. , Thesis (MA) -- Faculty of Business and Economic Sciences, School of Management Sciences, 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: A large part of this computational study focussed on selectivity patterns for 4-penten- 1-oxyl radical 1,5- and 1,6-cyclisations and for those of analogous 5-hexenyl, 4- penten-1-aminyl, 4-penten-1-iminyl and 3-phenylpropan-1-oxyl radicals. The study furthermore included cyclisation reactions of the radical cations of 4-penten-1-ol and 3-phenylpropan-1-ol. Calculations were performed for all applicable species involved in the two cyclisation modes studied, i.e. 1,5- and 1,6-cyclisation. These species included radical and radical cation precursors, as well as relevant radical transition state structures and radical adducts. All cyclisation systems investigated used the Density Functional Theory (DFT) functional B3LYP with a combination of eight basis sets. Each basis set used was a progressively higher level of theory than B3LYP/6-31G* which was used as a starting point. Cyclisations for unsubstituted species, e.g. the 4-penten-1-oxyl radical 1,5- and 1,6-cyclisations, were also simulated using the ωB97X-D and ωB97X-V functionals which account for dispersive effects. The same set of eight basis sets were used with these two functionals. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021
