- Description: According to the South African criminal justice system, where two or more people in a joint unlawful enterprise associate to commit a crime with only one participant carrying a firearm, the principles of joint possession are used to secure successful prosecution of the participants for joint possession of the firearm. However, up to date, the State is yet to see a conviction based on the application of these principles. S v Khambule marks the first case in which the doctrine of common purpose was used to secure a conviction of multiple accused for the crime of joint possession of firearms. The case has become outdated law following the Supreme Court of Appeal decision in S v Mbuli where the court found that the doctrine could not be applied to circumstance crimes such as joint possession of firearms. Both cases have received enormous criticism from academics and in subsequent judgments. One main criticism relates to whether the failure to apply the doctrine of common purpose is consistent with the current law and constitutional freedoms, such as the right to be free from all forms of violence and the right to equal benefit of the law. The purpose of the dissertation is to evaluate the jurisprudence on the application of the doctrine of common purpose to the joint possession of firearms. The evaluation includes an analysis of the principles of joint possession in the context of constitutional rights as well as contributions made by academics such as Burchell. The commonpurpose doctrine does not extend to joint possession of firearms. This is as a result of firstly, the absence of causation from the definitional elements of the crime; secondly, the mental aspect of possession; thirdly, the principles of joint possession as the basis of liability for joint possession of firearms; and lastly due to the nature of the crime of joint possession of firearms, being a circumstance crime. The paper recommends the extension of the doctrine of common purpose to joint possession of firearms. The recommendation is based on the following arguments. Firstly, the mental aspect of possession relates to the description of the article and not fault. Secondly, the doctrine is and has always been intended to criminalise joint wrongdoings. Thirdly, the extension of the doctrine of common purpose to joint possession of firearms is consistent with the presumption of possession in terms of the Firearm Controls Act. Lastly, the expansion enhances constitutional rights and fulfils the duty of the State to make South Africa less vulnerable to firearms. , Thesis (LLM) -- Faculty of Law, Criminal and Procedural Law, 2021

- Description: The study will address the application of the Prevention and Combatting of Corrupt Activities Act (PCCAA) and the various offences that is created by PCCAA and how the coutls apply PCCAA in corruption cases. This study will compare the crimes that was created under the repealed Corruption Act with the crimes created under PCCAA, lt will further show how the courls interpreted the application of PCCAA. The infamous case of former police commissioner, Jacki Selebi will be discussed and how the Supreme coutl of Appeal applied section 4 of PCCAA. lt will furlher explore why section 5 of PCCAA needs amendment to be able to prosecute foreign public officials under PCCAA. The PCCAA Amendment Bill is currently before parliament to amend section 5 of PCCAA. This study will further explore how corruption is dealt considering hospitality and gifts. This must be the most unnoticed form of bribery that occurs which PCCAA does not specifically clearly addresses. This will shorlly be compared to the German Penal Code. All legislation has strengths and weaknesses, including PCCAA. This study will explore those strengths and weaknesses and how they can be solved. lt will explore loopholes within PCCAA and the strategy of 'unbundling' corruption and its effects. lt has been stressed by the courts that corruption is a very serious crime and therefore the reporting thereof is impoftant. This study will discuss the reporling of corruption in terms of section 34 of PCCAA. This study will fufther show through South African case law that the courls are too lenient when sentencing individuals guilty of corruption and that the minimum sentence needs to be the starting point for sentencing offenders. The courts should not have discretion to deviate from this minimum sentence given how serious the courls express corruption to be and the devastating effects it has. , Thesis (LLM) -- Faculty of Law, Criminal and Procedural Law, 2021

- Description: Globally, the focus of many governments is on achieving universal health care for the citizens. In ensuring universal health care for South Africans, a National Health Insurance scheme has been established with a special focus on ensuring efficiency and effectiveness in the health sector. South Africa is reforming its health care system by the implementation of the NHI scheme which is seen by the South African government as the key to addressing the shortcomings and disparities in the health care sector in the country. The primary aim of this study was to review the available literature and policies related to the benefits and the problems around the NHI in South Africa. The study sought to determine the benefits associated with the implementation of NHI, to identify the possible challenges that may affect the effective implementation of NHI and to give recommendations based on the study on how the NHI can be implemented in a sustainable way. The Agency theory was adopted as a theoretical framework that guides the study. A qualitative research approach was utilised with the use of the exploratory and descriptive research designs. The data was collected through document analysis and thematic analysis was utilised to analyse the collected data. The findings show that the implementation of NHI in South Africa is beneficial as it will address issues of inequality and scarcity within the health care sector. Notably, there are some underlying shortcomings of the South African health care system which are likely to also affect NHI effective implementation. These include capacity of the government, corruption, mismanagement, wastage of resources, unequal distribution of health care professionals, and lack of knowledge on the part of the health care practitioners. This study concludes that these issues need to be addressed for the effective and efficient implementation of the NHI in South Africa. The study recommends strengthening monitoring and evaluation, accountability, training of more health professionals, conducting a baseline survey and building capacity of the government to implement NHI successfully. , Thesis (MPhil) -- Faculty of Business and Economic Sciences, Development Finance, 2021

- Description: This treatise discuses, the effectiveness of the Prevention of Organised Crime Act (POCA), specifically, Chapter Four of the Act. POCA was enacted for the purposes of tackling, inter alia, the threat posed by money laundering, racketeering and criminal gang activities. Moreover, POCA was enacted to supplement the common law, specifically the doctrines of common purpose, conspiracy, public violence as well as incitement. In this respect, the legislative framework in line with POCA- aimed at addressing money laundering and racketeering have contributed significantly in addressing such crimes. However, the same cannot be said about its effect on dealing with criminal gang activities. The criticisms which have been raised for the increase of criminal gang activities are that the sentences provided for in Chapter Four of POCA are viewed as inadequate in terms of deterrence because they are too lenient. The sentences do not hold gang leaders accountable but rather focus on foot soldiers. Likewise, POCA is similar to and does not expand the common law. This treatise aims to demystify the issues relating to criminal gang activities in South Africa. It investigates the extent to which Chapter Four of POCA adds significant value to the common law in respect of criminalising criminal gang related activities. It concludes and make recommendations on how criminal gang activities can be tackled while upholding South Africa’s constitutional values.bstract text. , Thesis (LLM) -- Faculty of Law, Criminal and Procedural Law, 2021

The purpose of this study was to evaluate the contribution of the Export Marketing and Investment Assistance (EMIA) for SMEs in the agro-processing sector in the Eastern Cape, with specific focus on East London and Port Elizabeth. A qualitative methodology meant to acquire in-depth knowledge was employed in the study. A case study was developed, in which EMIA’s contribution to SMEs’ export was the case in study. A group of seventeen participants, which included government officials and SMEs were interviewed and thematic analysis was used to evaluate the contribution of EMIA to agro-processing SME exports. The study found that EMIA was useful towards SME exports but lacked on addressing key barriers to exports faced by SMEs. The study recommends that government should place more emphasis on linking SMEs with proper contacts of buyers in international markets and that SMEs should be incentivised for costs relating to logistics for initial export orders. , Thesis (MPhil) -- Faculty of Business and Economic Sciences, Development Finance, 2021

- Description: At the turn of the twenty-first century, advancements in technology evolved at an exponential rate. This surge was mirrored by the rise in popularity and uptake of social networking sites (SNSs), and more recently, by Instagram, especially among emerging adults. SNSs have become an indispensable part of our daily lives and are influencing the ways individuals communicate, and develop and maintain romantic relationships. The Couple and Family Technology (CFT) Framework describes how the ecological elements of technology influence the structures and processes of romantic relationships, and is the lens through which this study was interpreted. The aim of this study was to determine if there was a relationship between Instagram use behaviours and relationship satisfaction amongst university students. This study employed a quantitative research approach and utilised a correlational research design. Participants included a sample of Nelson Mandela University students (N = 231) who were recruited through the nonprobability sampling methods of convenience and purposive sampling. Data were captured online through two measures. The biographical and Instagram use survey measured three variables, namely, frequency of Instagram usage, frequency of monitoring one’s partner’s Instagram activity, and frequency of posting behaviour. The Relationship Assessment Scale measured relationship satisfaction. Significant negative relationships were found between relationship satisfaction and frequency of Instagram usage and frequency of monitoring one’s partner’s Instagram activity. This research study contributed towards the existing body of knowledge, theoretical model, as well as insights for future lines of study within the realm of cyberpsychology. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: Having deduced from literature that millennials have a very high employee turnover, the purpose of this study was to gain a deeper understanding of what factors would make millennial Chartered Accountants in South Africa, or (CA)s, stay with or leave organisations. This is a case study within a qualitative research paradigm and followed an interpretivistic approach. A purposeful sampling technique was used in selecting a sample of seven millennial CAs for data collection. The sample constituted millennials who had changed jobs at least once in the past five years as these fell within the scope of this study. Semistructured interviews were conducted virtually using an interview guide as a data collecting instrument. Data saturation was reached after the interview of the sixth participant. The interview process provided a good blance of subjective views, opinions, emotions, and values of all participants. Having transcribed the interview transcripts, a manually detailed coding process was completed. Eight main emerging themes were identified which ultimately provided responses to the research questions. The data analysis revealed that millennial CA(SA)s prioritise, and in fact, demand flexibility coupled with a work-life balance. They expect their employers to understand and be supportive of these expectations. Other important retaining factors for this cohort of employees include, amongst others; training and development opportunities, growth, diversity, obtaining performance feedback, and coaching. An important issue that participants highlighted is the importance of ethics at work and or ethical leadership. The researcher could not probe more into this due to time constraints. This is recommended for further research. Having interviewed only six participants, this relatively small number poses a limitation to this study as these findings cannot be generalised to apply to all millennial CAs in South Africa. The data collected however, provided useful recommendations to employers looking for ways to retain millennial Chartered Accountants. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: The South African city faces an ongoing struggle with adequate social and spatial justice. Citizens have become separated and cultures have been divided owing to the historical formation of the city and the post legislative laws. Because of the growth of cities, certain resources are difficult to access and people need to trav el vast distances and cross dangerous barriers in order to access these resources. This thesis involves the research of social and spatial justice within the South Afri can city, which has resulted in a poor quality of life and a lack of resources. More specifically this thesis aimed at creating an environment that will aid in a better quality of life through spatial and social equity by creating an active and positive space to access certain resources.

- Description: The South African city faces an ongoing struggle with adequate social and spatial justice. Citizens have become separated and cultures have been divided owing to the historical formation of the city and the post legislative laws. Because of the growth of cities, certain resources are difficult to access and people need to trav el vast distances and cross dangerous barriers in order to access these resources. This thesis involves the research of social and spatial justice within the South Afri can city, which has resulted in a poor quality of life and a lack of resources. More specifically this thesis aimed at creating an environment that will aid in a better quality of life through spatial and social equity by creating an active and positive space to access certain resources. The particular focus area is the rural community of Pellsrus in Jeffreys Bay. The context has been analysed to enable a sound understanding of the formation of the town, the behaviour of the town and its people, the urban conditions and the spatial structures. Research lead to a site being selected that would form an transition space connecting separated communities and resources.

- Description: The identity of youth is an important developmental pro - cess in young people’s lives. Youth Centres in South Africa mainly focus on reproductive health services and as a result thereof, are experiencing low visitor num - bers and failing to captivate the youth whom they aim to serve. The very nature in which this takes place today, opens the door for an architectural intervention that has the potential to facilitate and improve this process. This thesis aims to address the issues that today’s youth faces by looking at the metaphorical representa - tion of the ‘street’ as the current place where the youth of today spend their time testing and developing their identity. It aims to rethink the youth centre as a place that combines youth culture and architecture to create a space which provides adequate recreational opportu - nities, and through which youths can reconnect to their surroundings - giving them a much-needed sense of place and identity within the ever-changing city. The idea is ultimately to design a Youth Activity Centre for the Parkside neighbourhood in East London - a de - sign which can express how youth identity can impact architecture in a way that can benefit the development of youth’s identity, and which can re-animate the nature of the ‘street’ through architecture. , Thesis (MArch) -- Faculty of Engineering, the Built Environment and Information Technology, School of Architecture, 2021

- Description: Small and medium enterprises (SMEs) internationally have a significant involvement in global economies, as they often are key drivers of economic growth through job creation, increasing production volumes, increased exports and imports. SMEs’ access to development finance and other financing products in the market remains one of the most significant constraints to the establishment, survival, growth, and productivity of SMEs. The South African Government has enacted policies to support SME development and enhance financial inclusion; however, the financing gap has proven to be persistent. Most SMEs cannot access various development and commercial credit funding due to a number of reasons, such as: the detailed complex financial documentation, own contribution and collateral required by finance institutions to grant loan finance; high cost involved in raising loan funding and high punitive interest rates due to the perceived high risk nature of the SMEs; and long time frames for the economic viability and business sustainability assessment processes for credit approval. In this study, a broad analysis of a viability based lending format of a development funding institution was conducted with the intention to develop a framework to assess its effectiveness to facilitate increased financial inclusion in the SMEs sector in KwaZulu-Natal. The study used the literature review to identify key factors that have an impact on economic viability and business sustainability/feasibility in terms of how these factors influence perceived financial inclusion of SMEs. The empirical section of the study tested SMEs’ perceptions and understanding of the concepts that influence the economic viability and business sustainability/feasibility of the SME sector. Strong evidence emerged from the empirical study that SMEs lack crucial resources such as own contribution to achieve an optimal equity structure in the business, lack of grant funding information available to support SMEs, lack of collateral required for funding security, lack of business support available to SMEs to compile comprehensive business plans and lack of own resources to manage various aspects of the business. Without appropriate coordination of the SMEs’ ecosystem, financial inclusion for SMEs will remain a challenge. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: The financial exclusion of the poor from the formal financial sector has contributed to the never ending cycle of inequality and poverty in South Africa. It is however evident from the R50 billion (Nasasa, 2020) generated each year in the stokvel market, that those previously excluded have been able to create their own informal market with immense potential. The full potential of the stokvel market has however not been adequately explored which has resulted in members not fully utilising this informal sector to improve their standards of living and the formal sector not providing adequate product solutions to benefit members. Majority of stokvels are still focused on traditional rotationally disbursement mechanisms designed for short-term goals (Zondi, 2016) and regardless of the market that has growth to be worth R50 billion, members are yet utilise funds accumulated on instruments and mechanisms to improve standards of livings for themselves, families and general communities. The formal sector provides stokvel savings products that offer stokvels with simple savings mechanism often generating little interests which may not necessarily provide the full potential benefit to the members. This was also shown in a study by African Response (2019) indicating that 40% of stokvels had their money invested in low to no interest accounts. Stokvels have also evolved and are now used for far more than just a simple savings mechanism, with some stokvels focusing on continuous rotationally mechanisms, while others focus on fixed periods. Stokvels can exist for different reasons including for groceries, burial, school fees and longer term purposes such as building houses or buying cars or a combination of these. Solutions available ought to therefore take into consideration the key needs of stokvels while considering short term and medium to long term solutions which current simple savings solutions offered by the formal sector may not completely offer. In keeping up with the market, banks may try to enhance their products but Moliea (2017) concluded that banks were being flexible on things that members did not require. Against the stated research problem, the primary objective of this research is to investigate how the traditional mechanisms of stokvels can be amended and improved to ensure maximum benefits/returns for its members; which benefits are not only long-term in nature, but also taking account of the short-term needs and realities of poor communities within the context of the South African economy. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: This thesis presents the development of a regional ionospheric storm-time model which forms the foundation of an index to provide a quick view of the ionospheric storm effects over South African mid-latitude region. The model is based on the foF2 measurements from four South African ionosonde stations. The data coverage for the model development over Grahamstown (33.3◦S, 26.5◦E), Hermanus (34.42◦S, 19.22◦E), Louisvale (28.50◦S, 21.20◦E), and Madimbo (22.39◦S, 30.88◦E) is 1996-2016, 2009-2016, 2000-2016, and 2000-2016 respectively. Data from the Global Positioning System (GPS) and radio occultation (RO) technique were used during validation. As the measure of either positive or negative storm effect, the variation of the critical frequency of the F2 layer (foF2) from the monthly median values (denoted as _foF2) is modeled. The modeling of _foF2 is based on only storm time data with the criteria of Dst 6 -50 nT and Kp > 4. The modeling methods used in the study were artificial neural network (ANN), linear regression (LR) and polynomial functions. The approach taken was to first test the modeling techniques on a single station before expanding the study to cover the regional aspect. The single station modeling was developed based on ionosonde data over Grahamstown. The inputs for the model which related to seasonal variation, diurnal variation, geomagnetic activity and solar activity were considered. For the geomagnetic activity, three indices namely; the symmetric disturbance in the horizontal component of the Earth’s magnetic field (SYM − H), the Auroral Electrojet (AE) index and local geomagnetic index A, were included as inputs. The performance of a single station model revealed that, of the three geomagnetic indices, SYM − H index has the largest contribution of 41% and 54% based on ANN and LR techniques respectively. The average correlation coefficients (R) for both ANN and LR models was 0.8, when validated during the selected storms falling within the period of model development. When validated using storms that fall outside the period of model development, the model gave R values of 0.6 and 0.5 for ANN and LR respectively. In addition, the GPS total electron content (TEC) derived measurements were used to estimate foF2 data. This is because there are more GPS receivers than ionosonde locations and the utilisation of this data increases the spatial coverage of the regional model. The estimation of foF2 from GPS TEC was done at GPS-ionosonde co-locations using polynomial functions. The average R values of 0.69 and 0.65 were obtained between actual and derived _foF2 over the co-locations and other GPS stations respectively. Validation of GPS TEC derived foF2 with RO data over regions out of ionospheric pierce points coverage with respect to ionosonde locations gave R greater than 0.9 for the selected storm period of 4-8 August 2011. The regional storm-time model was then developed based on the ANN technique using the four South African ionosonde stations. The maximum and minimum R values of 0.6 and 0.5 were obtained over ionosonde and GPS locations respectively. This model forms the basis towards the regional ionospheric storm-time index. , Thesis (PhD) -- Faculty of Science, Physics and Electronics, 2021

- Description: The “South African education system is grossly inefficient, severely underperforming and egregiously unfair” (Spaull, 2013, p.3). In particular, grave concerns with learner performance in mathematics in South Africa are well documented (e.g., Taylor, 2008; Spaull, 2013; Venkat & Spaull, 2015). There are various explanations for the poor state of learner performance in mathematics in South Africa. Two of the explanations that relate closely to my research interest are teachers’ insufficient mathematics content and pedagogical knowledge, and inappropriate professional development. This study aims to ascertain how a collaborative intervention can develop teachers’ mathematics and pedagogical content knowledge as they focus on developing learners’ foundational number sense. Cultural Historical Activity Theory, together with Mathematics Knowledge for Teaching (Ball et al., 2008) and the Knowledge Quartet (Rowlands & Turner, 2007) frameworks, provide the explanatory and analytic tools for the research. The research is a qualitative case study underpinned by an interpretivist orientation. The study was conducted at a township public primary school in the Northern Cape. Three Grade One teachers participated in the research. Data was collected through interviews, classroom observations, and videos of collaborative lesson planning and reflection sessions. A key finding emerging from this research is that the teachers had the necessary mathematics content knowledge to teach Grade One mathematics. Despite this and in contrast to it, they lacked adequate pedagogical content knowledge required to develop learners’ number sense. To develop their pedagogical content knowledge, they required the intervention of a ‘more knowledgable other’ (Vygotsky, 2008). Several contradictions and tensions emerged from the research. For example, the teachers expressed that the opportunity to work collaboratively was beneficial, but it was evident that they were familiar with and accomplished in planning and working together. The contradictions emerging from this research provide an opportunity and basis for expansive learning for future collaborative teacher endeavours. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: South African labour law is founded on the fundamental constitutional right of fair “labour practices”. This fundamental right is afforded to both the employer and workers. This means that in the employment relationship, there are two competing rights involved which necessitate the need to strike a balance when each party’s rights are exercised. Therefore, this right is not absolute, and it is subject to limitations as per the provisions of section 36 of the Constitution. The Labour Relations Act, amongst other labour law resources considered in this research, give effect to those competing rights and seek to strike the necessary balance by establishing guidelines to protect the individual employee against unfair dismissals, amongst other things. It requires that the dismissal of an employee be fair. This requirement is met where two elements are fulfilled: (1) substantive fairness and (2) procedural fairness. The purpose of this study is to focus on “misconduct” as a valid reason for dismissal, as well as “group or team misconduct” which is included in the notion and ambit of “misconduct”. This type of misconduct involves a group or team who the employer has identified as having committed a misconduct, but the employer, due to different reasons explored in this research, is unable to identify the specific individual employees directly involved in the primary misconduct it wishes to prosecute. Therefore, the employer formulates a disciplinary charge of “group or team misconduct” to discipline the entire group or team. This group or team may form part of the entire workforce or a team within a department of the employer’s business. , Thesis (LLM) -- Faculty of Law, Mercantile Law, 2021

- Description: The arrival of China in Malawi has been characterised by a growing sense of uncertainty where academics and social commentators at large have expressed concern over the intentions of the super power in the country. There are fears that China would like to extend its influence to Malawi as part of a broader push, to have greater influence in global politics and economics. That push is in part exercised through the media. The thesis examined the perception of Malawian journalists on how news media reports on Chinese activities in Malawi. It used content analysis to understand how the mediascape had changed from 2001 – 2007 when China had not established diplomatic relations with Malawi, and January 2008 – 2020 when China had established diplomatic relations. The thesis examined these shifts in journalistic representations of China in Malawi and developed prompts and probes from which journalist interviews were conducted. From the content analysis, it appears there is a remarkable change in the way China has been covered from 2001 – 2020. From 2001 – 2007, Malawian media, especially The Daily Times, was very harsh on China, uncritically reproducing Western representations of China as an aggressive country with no respect for human rights and dignity. This changed after January 2008 when the media leaned towards tolerance and acknowledgement of Chinese activities. Through interviews, journalists have indicated that the Chinese government offers opportunities, such as scholarships, fellowships, and exchange visits to journalists, making it difficult for them to bite the finger that is feeding them. This ‘soft power’ is backed up by the repressive power of the Malawi government, which uses intimidation to force journalists to report in their favour, thereby helping create a positive picture for China in Malawi. Journalists report that the significant shifts in journalistic representations of China have been mirrored by changes in the conceptualisation of journalistic roles in Malawi’s mediascape. , Thesis (MA) -- Faculty of Humanities, Journalsim and Media Studies, 2021

- Description: The infrastructure and use of the Internet have developed rapidly in recent years, which propelled traditional human resources systems into a new electronic human resources (E-HRM) approach. This cannot, however, be regarded as a one-size-fits-all solution as employees across different generational cohorts are not all at the same comfort level with regard to operating such web-based applications. It is the researcher’s opinion that the latter may affect employee engagement as this appears to be the case within the researcher’s own organisation. Employee engagement is important in providing organisations with the competitive advantage required to operate in a highly competitive market. Employee engagement levels are far from ideal across many organisations, which require these organisations to identify solutions to raise overall engagement levels. With age rapidly becoming a more important diversity factor, it is imperative for managers to understand the effect of E-HRM on employee engagement across the generational cohorts to design the most beneficial HRM strategy for their organisation. The purpose of this study is to gain a better understanding on how generational cohorts are affected by the application of E-HRM programmes and to identify whether there are substantial variances between the engagement levels of the different generational cohorts in this context. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: Background: Limited information related to changes in both the metabolic and blood profiles of healthy young adults engaging in either high-intensity interval training (HIIT) or moderate-intensity continuous training (MICT) modalities exists. The detrimental effects of sedentary lifestyles can be moderated and may be dependent on the intensity of the intervening activity. It is well known that regular physical activity (PA) can improve a person’s cardiorespiratory fitness (CRF) and therefore mitigate potential life-threatening effects of sedentary behaviours. Yet despite this, globally, approximately one out of every four adults fail to meet the minimum PA guidelines. Methods: Twenty-eight recreationally active adults from Nelson Mandela University (NMU) initially volunteered to participate in the study. The study was advertised on social media and via the NMU email MEMO database. Eight (n=8) participants were excluded from the study analysis as they failed to complete all the required testing sessions (illness: n=3; failure to attend 80% of sessions: n=2; lost interest: n=3), resulting in a total sample of 20 participants that were retained for analysis (HIIT (n=10) and MICT (n=10)). For inclusion to the study, all participants were required to: (i) be healthy before and during the testing period (ii) be between 18-35 years of age, and (iii) be free of injury before and during testing. Participants attended three training sessions per week for six weeks. HIIT and MICT interventions were matched for exercise load. Results: Within-group differences (i.e. pre- vs. post-intervention) were present, specifically for cardiovascular adaptations including maximal oxygen uptake (HIIT: +17.40%; MICT: +16.11%), gas exchange threshold (HIIT: +14.50%; MICT: +10.83%) and peak power output (HIIT: +38.92%; MICT: +33.79%), but not for cardiometabolic (p = 0.11 – 0.81). No between-group differences were evident for any measured parameters (p = 0.24-0.97), showing no clear preference for either HIIT or MICT modality. Conclusion: Acute improvements in CRF and metabolic biomarkers appeared to be independent of exercise intensity and were achievable within a relatively short time frame. , Thesis (MHMS) -- Faculty of Health Sciences, 2021

- Description: Phase change materials (PCMs) have been incorporated into clothing and textiles to provide added value in terms of thermoregulation and thus added comfort to the wearer in extreme weather conditions and sporting activities. Since clothing is laundered many times during the service life of the textile, the effects of simulated domestic laundering on the physical and thermal properties of a non-woven textile which contains PCMs were investigated. The thermal properties, such as the thermal degradation, melting, evaporation and crystallisation were measured by the TGA and DSC analytical techniques. The physical properties, such as the microcapsule size distribution, and the microcapsule morphologies of the PCM microcapsules, were measured by the SEM and Raman analytical techniques. The main objectives of this study were to determine the effect of repeated laundering at different wash temperatures on the mass loss, enthalpy, and physical changes in PCM. Thermal degradation as determined by TGA thermograms was found to be higher at a wash temperature of 60°C relative to that of a wash temperature at 30°C, the mass loss being 4.6% more at 60°C than at 30°C. This was asserted to physical changes such as size and shape of the PCM microcapsules as evident in SEM images. The SEM images showed broken and collapsed PCM microcapsules in the web and around the fibre, indicating evaporation of the thermoregulating content of the PCM. It was found that the heat capacity of the sample washed at 60°C was much lower than that of the unwashed sample, the difference being approximately 50% in terms of the latent heat capacity as determined by DSC thermograms. This implies that the latent heat effectiveness of the PCM has decreased significantly. The physical properties of the PCM such as the intermolecular interaction, the intensity and width of peaks, polarisation, degree of crystallinity and the orientation changed as illustrated in the Raman analysis. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: The growth and feed conversion ratio of farmed abalone Haliotis midae (L. 1758) fed a formulated diet varies in feeds with different protein sources. To better understand this, the effect that various combinations of dietary soybean meal (SBM), sunflower meal (SFM) and fishmeal (FM) had on the digestive efficiency of farmed H. midae when included in a formulated feed, were assessed. The aim of this study was to investigate the effect that plant-based proteins had on abalone digestion and gut-bacterial profile of cultured adult abalone when combined with fishmeal. This was done by analysing the chymotrypsin (protease) and cellulase (carbohydrase) digestive enzyme activities from whole-gut sections of farmed abalone that were fed one of four diets for 12 months: FM-only, SBM-only, fishmeal and soybean meal (FM-SBM), and fishmeal and sunflower meal (FM-SFM). There were significant interactions between the diets, sampling date, and sex of the abalone, which had an influence on the cellulase activities in the digestive tracts of the animals. Those fed the SBM diet had the highest cellulase activity by the end of the sampling period (ANOVA; df = 9; F = 2.9; P = 0.005). The significant interactions between diet and sampling date influenced the chymotrypsin activities of abalone. Animals fed the FM diet had the highest activity of chymotrypsin for most of the sampling period (ANOVA; df = 9; F = 2.5; P = 0.01). Therefore, diet did have an impact on the cellulase and chymotrypsin activities of abalone fed either combination diets (FM-SBM; FM-SFM) or single protein diets (FM; SBM). The presence of plant material such as cellulose fibres in the diets containing plant proteins may have influenced the cellulase activity levels of each treatment as it would have stimulated endogenous and exogenous cellulase production. However, treatments with the highest crude fibre content, SBM and FM-SFM, resulted in differing activities. The activity levels of chymotrypsin may have been impacted by the protein type, presence of protein inhibitors and temporal changes in utilisation. Abalone fed the FM diet exhibited the highest chymotrypsin activities on sampling day 182, which was in summer. Animals fed the treatment diets containing fishmeal also developed their reproductive tissues, and may explain the low chymotrypsin activities in abalone fed SBM-only. Additionally, the presence of allergenic compounds would have influenced enzyme activity, as they would have negatively affected the nutrient utilisation and absorptive capacity. Fluctuations in water temperature may have had an effect on enzyme activity, as activities were highest during summer, when seawater temperatures are most variable. A change to lowered water temperatures are known to trigger the growth of digestive epithelial tissue in abalone to allow for increased enzyme secretions and nutrient absorption (Schaeffer et al. 2013). The effect that plant protein inclusion in abalone diets had on the gut-microbiota was revealed by analysing the differences in gut-bacterial community profiles, through the use of metagenomic sequencing. The relative abundance of the phylum Verrucomicrobia, class Verrcomicrobiae and the genus Rubritalea were highest in the SBM diet. These bacterial groups were also influenced by the plant material from soybean meal, as hydrolysed cellulose is broken down by cellulases, and allowed for the proliferation of Rubritalea bacteria due to them using cellobiose as an energy source. The presence of Bacteroidetes was due to the phyla having bacterial species that can breakdown proteins and species that can break down carbohydrates. The animal protein present in the composition of the FM diet had a positive influence on proteolytic Bacteroidetes growth. The high levels of cellulose from the plant fibres in the soybean meal-only diet (SBM) promoted growth of saccharolytic Bacteroidetes. Tenericutes bacteria’s prominence was due to the higher plant fibres from the soybean meal as some Mycoplasma are known to degrade polysaccharides. Therefore, exposure to formulated feeds with high levels of these plant materials would allow for high proliferation. The thesis established that plant-derived dietary proteins in formulated feeds result in an effect on digestive enzyme activity and a difference in the community structure of gut bacteria in H. midae abalone. The results from the current research highlight the importance of studying abalone gut physiology when investigating the impacts of formulated feed composition, and can be used as an additional factor when determining the efficacy of a dietary component. Further research on the gut-bacterial groups and different digestive enzymes of H. midae abalone is encouraged, in order to create a holistic view on their response to dietary plant proteins inclusion in formulated feeds, thus reducing the need for fishmeal protein. , Thesis (MSc)-- Rhodes University, Faculty of Science, Department of Ichthyology and Fisheries Science, 2021
