- Description: Previous research has established a relationship between exercise and cognition, with more emphasis on this ascertained link, being made on the effects of long term and endurance exercise on cognition. However, enhanced worker effectiveness relies on a strong acute collaboration of physical and cognitive performance during task execution. As a result, the purpose of this study was to examine the acute effects of extended aerobic exercise on visual perception, working memory and motor responses, and to achieve this 24 participants (12 males and 12 females) aged between 18 and 24 participated in a 2 bout cycling exercise. The experimental condition had cycling resistance set at 60 percent of each individual’s maximum aerobic output and the control condition had zero cycling resistance, where three cognitive tasks were performed at 10 minute intervals during the cycling exercise. The results showed that exercise did not affect any significant changes on the cognitive performance measures over the entire cycling duration, as well as during the exercise phase (cycling with resistance). However, visual perception improved significantly (p<0.05) immediately after exercise. This led to the conclusion that moderate to high intensity exercise when performed for an extended duration, has selective effects on certain cognitive performance measures, with the time at which the performance is measured during the exercise being a relevant factor to be considered for maximum activation effects of the exercise.

- Description: The hydrometallurgical refining of platinum group metals results in large volumes of liquid waste that requires suitable treatment before any disposal can be contemplated. The wastewater streams are characterized by extremes of pH, high inorganic ion content (such as chloride), significant residual metal loads and small amounts of entrained organic compounds. Historically these effluents were housed in evaporation reservoirs, however lack of space and growing water demands have led Anglo Platinum to consider treatment of these effluents. The aim of this study was to investigate whether biological wastewater treatment could produce water suitable for onsite reuse. Bench-scale activated sludge and anaerobic digestion for co-treatment of an acidic refinery waste stream with domestic wastewater were used to give preliminary data. Activated sludge showed better water treatment at lab scale in terms of removal efficiencies of ammonia (approximately 25%, cf. 20% in anaerobic digestion) and COD (70% cf. 43% in digestion) and greater robustness when biomass health was compared. Activated sludge was consequently selected for a pilot plant trial. The pilot plant was operated on-site and performed comparably with the bench-scale system, however challenges in the clarifier design led to losses of biomass and poor effluent quality (suspended solids washout). The pilot plant was unable to alter the pH of the feed, but a two week maturation period resulted in the pH increasing from 5.3 to 7.0. Tests on algal treatment as an alternative or follow-on unit operation to activated sludge showed it not to be a viable process. The activated sludge effluent was assessed for onsite reuse in flotation and it was found that there was no significant difference between its flotation performance and that of the process water currently used, indicating the effluent generated by the biological treatment system can be used successfully for flotation. Flotation is the method whereby minerals refining operations recover minerals of interest from ore through the addition of chemicals and aeration of the ore slurry. Target minerals adhere to the bubbles and can be removed from the process.

- Description: Primarily, this research study was concerned with the evaluation of the brand campus concept implemented at then DaimlerChrysler South Africa in 2002, as a case study. Pretoria-based Mercedes-Benz South Africa (Pty) Ltd. (MBSA) is a subsidiary of global vehicle manufacturer Germany’s Daimler-Benz AG (DBAG). They are responsible for assembling, distributing and retailing, certain Mercedes-Benz and Mitsubishi vehicle brands, and spare parts. The landmark 1998 DaimlerChrysler global ‘merger of equals’ was preceded by the 1995 joint venture between Mercedes-Benz and Mitsubishi Motor Corporation. Consequently, three brands (Mercedes-Benz, Chrysler and Mitsubishi) were retailed and marketed under DaimlerChrysler South Africa (Pty) Ltd. (DCSA), positioned next to each other in the same showroom. This report identifies key challenges stemming from this approach, namely: brand strength dilution, more than 80 multi-franchised dealers and multi-branded showrooms, service capacity problems, old working environment and infrastructure, and perceived intra-brand competition. The research evidence suggests that these problems prompted then DCSA to launch the 2000 Dealer Network Strategy (DNS). In the grand scheme of things, the DNS intervention entailed partitioning the dealer network into five brand centres in five metro regions, and eighteen market centres in the rural areas. The brand campus concept was borne out of DNS and proved to be a masterstroke since, the primary focus was on streamlining the retail facilities for DCSA vehicle sales, service and spare parts for both the passenger and commercial vehicles. This study highlights key pillars of the brand campus concept, namely: profitability, brand focus, customer orientation and diversity. The challenge was to address seven major drivers of the brand campus concept, namely: after-sales vehicle support, vehicle service capacity, lead-times, spare parts availability, sales information propagation, behavior of sales personnel and the overall vehicle dealership appearance. Semi-structured interviews constituted part of the evaluation based on the perspectives of five customers, three dealer principals and two MBSA marketing executives. The research evidence, which also came from MBSA documentation and direct observation, shows that this innovative concept has been remarkably successful.

Colour vision of the citrus psylla Trioza erytreae (Del Guercio) (Homoptera: Psyllidae) in relation to alightment colour preferences

- Description: The colour vision of adult citrus psylla, Trioza erytreae, was investigated in the laboratory using the behavioural parameters: alightment and walking. Light green flushing leaves (under which the nymphs develop) were significantly preferred, visually, to dark green mature leaves for alightment. Diffuse reflectance spectroscopy showed (when expressed in the parameters of human colour vision) that flush has a very slightly longer dominant wavelength, and roughly double the reflectance and purity. Alightrnent frequency correlated almost equally well with "purity" (as noted by Moericke, 1952 et seq., in "yellow-sensitive" aphids) as with the aphidological colour parameter "long/short ratio" developed by Kennedy et al. (1961). Elucidation of the mechanism underlying the citrus psylla's alightment colour preference was initially attempted with a printed spectrum and several paint series of measured spectral characteristics. It was clear that T.erytreae belongs to the "yellow-sensitive" group of Homoptera, but it was impossible to distinguish which pararneter(s) of colour the psyllids were responding to. Phototactic (walking) response to the individual parameters of colour was therefore measured using a monochromator. The phototactic action spectrum (against wavelength) was tri-modal, with peaks in the yellow-green (YG), blue (B), and ultra= violet (UV). Rate of phototaxis was not influenced by bandwidth (roughly equivalent to purity), but was proportional to intensity (roughly equivalent to reflectance). To investigate the influence of the above three wavelength regions on alightment, use was made of a very simple flight chamber incorporating a target of coloured light. Yellow-green and UV light both independently stimulated alightment . Their effect was additive. Different thresholds indicated distinct YG and UV receptor systems. Blue light alone did not stimulate alightment, and was strongly alightment-inhibitory in combination both with YG and with UV light. On the basis of the above physiological/behavioural findings, a new alightment formula was drawn up for describing the hamopteran's apparent manner of alightment determining integration of surface reflectance. The flush preference and alightment distributions on the series of artificial surfaces were found to correlate slightly more accurately, on average, as well as more consistently, with the new formula than with previously-available colour parameters. These findings are placed in perspective to the literature, and their possible economic relevance is discussed.

- Description: Two and a half billion people mostly in sub-Saharan Africa and southern Asia remain without improved sanitation facilities despite the Millennium Development Goal 7's target to halve this number by 2015. While it might be tempting for developing countries such as South Africa to implement the cheapest and most rapidly constructed sanitation services simply to meet the desired target, this could have significant negative implications on human health and the environment over the long-term. As a result, there is a need to ensure that the most appropriate sustainable sanitation technologies are selected during the planning stage. The purpose of this research was therefore to document the development and pilot application of a flexible context-specific decision-support tool for sustainable sanitation technology selection within Buffalo City Municipality (BCM) in the Eastern Cape Province of South Africa. The first step in the development process was to ascertain the current status of sanitation within the municipality, with a specific focus on the main challenges related to the provision, maintenance and performance of these technologies. Thereafter, a participatory approach was employed involving BCM stakeholders to develop a series of sustainability criteria and indicators that took into consideration economic, social, environmental and technical concerns as well as legal requirements. The development process resulted in a list of 38 BCM sustainable sanitation selection criteria that were applied in a pilot study involving rural, urban and peri-urban communities within BCM. Certain criteria related to topographical features and the availability of piped water and land were considered useful for 'coarse screening' while others were applied during 'fine screening'. In order to enhance the context specificity of criteria, each was weighted, through consultation with key BCM stakeholders. This research confirmed that the sanitation situation in BCM was poor and preliminary evidence indicated that sanitation systems were negatively impacting on the quality of water resources within BCM justifying the need for a sustainable sanitation decision support tool. Based on the pilot application of the BCM Sustainability Selection Criteria List, the urine diversion technology was considered the most sustainable technology option in each study site. There were however, certain social criteria that received relatively low sustainability scores and these would need to be addressed prior to the approval of this technology for implementation. The approach adopted in this thesis was considered highly context-specific yet flexible and appropriate for adoption not only by BCM but other municipalities on a range of spatial scales.

- Description: A well known fact about any work of art of any significance is its power to upset current conventions and disturb certain of our normal emotional patterns. The artist frequently achieves this by deliberately expressing emotions that are violent. There is nothing, however, new about the existence of violence in the arts, a large number of works in the history of art being painted with blood. One has only to think of the many battles, rapes, murders, martyrdoms and catastrophes that have been the subjects of many great paintings. Since the beginning of this century, and especially since the work of the Impressionists, in which violence is entirely excluded, violence has taken on a role of great importance and has been used to a greater or lesser extent by artists and group movements. It would appear initially that there are two main reasons in this century for the use of violence: one as a means of using it as a weapon against the academic and avant-garde in the arts, which in turn reflects attitudes found in society, and secondly as a direct reflection of the corrupt society in which we live. This is not to say that the twentieth century is an age in which more violence and sadism is found than in any other era of history, but never has it received so much publicity. I do not believe that man has change so much over the years, but it is my view that the apparent increase in this century is due to the vast changes in communications, it is due to the publicity it receives that violence has in recent times become a focal point, with murders, assassinations and war part of our daily lives. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 1971

- Description: This thesis is a reception analysis using qualitative interviews to investigate the formation of cultural groups around computer-game LANs present in Rhodes University. It also looks at how issues of social inequalities evident on the university's campus impact on the participation of students in these LANs. The findings of this study are that the participants have established a community around the practice of computer LAN-gameplay based on values developed through the combination of the material and gameworlds. It serves as a home-on-campus for them; where they can fully explore their passion for games thus reaffirming their identity as gamers on a campus where being a gamer is viewed negatively. In this light, computer-game playing is not just a practice these participants perform, but a culture they live out every day. This is a culture predominantly lived out by men. One of the reasons for this is because most women have been raised to believe to have negative predispositions about digital gaming e.g. that it is childish, addictive and anti-social, but also that computer are meant to be used by men - women use them only when it is absolutely necessary, for example, that it is childish, for academic-related purposes. As a result, not many of them will use computers for any otherreason for fear of being socially criticised. In addition, the gaming culture being dominated by whites is due to the fact that admittance in to this community is still unaffordable for the majority of black students on the Rhodes University campus as a result of their social backgrounds.

- Description: This thesis is a reception analysis using qualitative interviews to investigate the formation of cultural groups around computer-game LANs present in Rhodes University. It also looks at how issues of social inequalities evident on the university's campus impact on the participation of students in these LANs. The findings of this study are that the participants have established a community around the practice of computer LAN-gameplay based on values developed through the combination of the material and gameworlds. It serves as a home-on-campus for them; where they can fully explore their passion for games thus reaffirming their identity as gamers on a campus where being a gamer is viewed negatively.

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

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

Assessing linkages between local ecological knowledge, HIV/AIDS and the commercialisation of natural resources across Southern Africa

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

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

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

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

- Description: Rhodeo is the Independent Student Newspaper of Rhodes University. Located in Grahamstown, Rhodeo was established in 1947, and renamed in 1994 as Activate. During apartheid Rhodeo became an active part of the struggle for freedom of expression as part of the now defunct South African Student Press Union. Currently Activate is committed to informing Rhodes University students, staff and community members about relevant issues, mainly on campus. These issues range from hard news to more creative journalism. While Activate acts as a news source, one of its main objectives it to be accessible as a training ground for student journalists. The newspaper is run entirely by the students and is published twice a term. Activate is a free newspaper which receives an annual grant from the Rhodes University Student Representative Council, however, majority of its revenue is generated through advertising.

- Description: This study investigates the literary activities of two emerging female Kenyan writers, Claudette Okwiri Oduor and Jacqueline Ndinda Kioko, both of whom are award-winning authors. Oduor won the 2014 Caine Prize for African Writing while Kioko bagged the Wasafiri New Writing Fiction Award 2017. It examines specifically how the writers deal with memory and mourning in negotiating between the past and future. I explore how their fictional and non-fictional narratives assist individuals and groups to confront loss, reconstruct new identities, and renegotiate belonging amidst personal and social upheaval. The fictional narratives at the centre of this research are Oduor’s “The Plea Bargain” (2011), “My Father’s Head” (2013) and “Rag Doll” (2014), and Kioko’s “Sometime Before Maulidi” (2014) and “Some Freedom Dreams” (2017). The study explores the themes of mental illness, existential crisis, and fragmentation, and considers bereavement, queer relationships, cultural freedom, and social recognition. The research further considers the active participation of these two writers in Kenya’s contemporary literary-cultural conversations, which span different genres and various media platforms, including blogs, YouTube clips, online magazines, and social media networks in dialogue with other writers. I trace the significance of the literary-cultural link these authors have with their local, continental, and global counterparts in countries like Uganda, Nigeria, and South Africa. The link finds expression through their (in)direct association with some of the new online publishing outlets in Kenya like Jalada Africa, Enkare Review, and Kikwetu. More importantly, their shared participation in and association with such international awards and scholarships as the Commonwealth Short Story Prize, Kwani Trust Manuscript Project, and Miles Morland Foundation is integral in apprehending contemporary literary exchanges and multidirectional flows of publishing in Africa and beyond. I equally illustrate how mentorship of younger writers through local writers’ organisations and collectives like AMKA and Writivism help in the formation of an alternative canon other than the mainstream. The study affirms that the authors seem to transcend the boundaries of production and circulation by fluidly moving between electronic and non-electronic platforms, thus mimicking the memory production of remembering, repeating, and working through.
