  • Description: This dissertation addresses the nature and potential of an intrusive architectural typology in a sensitive river estuary environment through an understanding of the functional design principles of an Aquaculture plant. Furthermore the research engages with cultural, historical and sociological objectives to celebrate the historical landscape. Hamburg is caught between its value as a historic wilderness and it's need to establish and maintain an economy to alleviate poverty. The project is conceived as a provocation and speculation on how these two demands may be hybridized as an alternative to the typical conservationist practices applied. Proposing a type of hybrid ecology where industry and endemic wildlife can not only co-exist but also be mutually beneficial.

  • Description: This research engages with a contemporary theoretical debate in the literary field, namely the ability of fictional texts to contribute to archival records. Contemporary research in archival discourse suggests that there are many intersections between fiction and the archive. Using Hamilton and others’ seminal text Refiguring the Archive (2002) and Pasco’s “Literature as Historical Archive” (2004) as point of departure, this dissertation offers an analysis of the South African English translation of Marlene van Niekerk’s Agaat (2004, translated 2006). In both form and function, the novel is viewed as a simulation of an archive. In Agaat, Van Niekerk has compiled a fictional archive of two indigenous South African cultures through her portrayal of the two main characters: Afrikaner culture during apartheid as embedded in the focalization of Milla de Wet and remnants of Khoi and/or San culture as emerge from the fictionalised subjectivity of her coloured housekeeper-nurse, Agaat. Through a conceptual and theoretical exploration of archival discourse, I argue that literary texts, such as Van Niekerk’s novel, have the potential to refigure (or creatively redefine) the archive and to enhance its scope and relevance, especially as South Africa undergoes transformation.

  • Description: Parasuicide is a problem that affects the youth locally and globally. Parasuicide has negative psychological impacts on youth. This study was designed to assess elements of parasuicide in the Buffalo City Metropolitan Municipality of South Africa, using records of patients admitted to Frere and Cecilia Makiwane hospitals between 2016 and 2020. The purpose of the study was to conduct a descriptive retrospective review of parasuicide among youth to determine trends, causes, and contributing factors of committing parasuicide. Methods A retrospective, quantitative and descriptive study was conducted with 200 files of patients aged between 18 and 35 years conveniently sampled. These patients diagnosed as committed parasuicide and were admitted at Frere and Cecilia Makiwane hospitals over a period of four years from 1 April 2016 to 31 March 202. Only record files of patients’ residing in East London and Mdantsane catchment area were selected. Raw data was collected for a period of twelve weeks using a developed data collection tool developed in Ms Excel spreadsheet. Results In this sample, the large number of the patients were under 26 years (60.5%), female (57%), single (92.5%), and Black (99.5%). Furthermore, majority of the patients had attained secondary education (89.5%), were unemployed (83%) and living with their families (59%). There were different methods and agents used by participants to commit parasuicide and reasons differed from person to person. Among patients who reported a suicide attempt, organophosphates were most commonly used agent for self-poisoning (47%, n=94), followed by substances such as use of drugs and alcohol (n=57, 28.5%), violence (n=27, 13.5%), corrosive agents including bleach and Jik (n=11, 5.5%), and hydrogen peroxide including acidic sub-stances like battery acid (n=11, 5.5%). The common reason found in the study and indicates participants had psychiatric disorder (34.5%). Conclusion Limiting access to organophosphate agents and other lethal means is an effective strategy that should be adopted to prevent parasuicide among youth. Timely identification of risks or warning signs, social prevention and immediate intervention at the state level will play an important role in controlling parasuicide among youth. Moreover, improving health care services with psychotherapy support would empower youth with skills that would enhance their self-confidence, self-worth and resilience. Consequently, attainment of these attributes would result in the prevention and control of parasuicide amongst youth. , Thesis (MPH) -- Faculty of Health Sciences, 2021

East London and its geographical setting

  • Description: Along the South African coast between Cape Town and Durban, a distance of 822 miles, are the two major ports, Port Elizabeth and East London. These two ports, rivals in some ways, have histories that are closely linked. Their harbours have been built at two of the most favourable spots along a coastline poorly endowed with natural harbours. East London, the fourth harbour of the Union of South Africa, is the only river port of any consequence, and had to win the mechanical fight against nature and the fight against prejudice that contended that her position was too close to a troublesome frontier. After a hundred years of growth, East London is a mature town, with the residential and industrial areas clearly defined. Her expansion will be along the lines of planned zoning. (2) Her population in 1950 was 910,195 of which 43,195 were European and 39,698 Native. Besides being a port, East London is a prominent holiday resort and, of recent years, is developing as an industrial town. A striking feature is the clean aspect of the town. Those two "miracles" of South Africa, the discovery of diamonds and the discovery of gold, stimulated the growth of East London; especially the discovery of diamonds since Kimberley was about 450 miles from this, its nearest harbour. But the river mouth at East London had very little natural advantage over the other river mouths along the coast. There was at the Buffalo Mouth no outstanding, decisive merit. In many matters, such as the railway, the bridge, the water supply, there was doubt, uncertainty and bickering, with subsequent decisions to shelve the latter or make use of a temporary expedient, because there were many mediocre alternatives but none which was supremely suitable. In 1852, Bishop Gray wrote, "East London ... .has as few natural advantages as any place I have seen claiming to be a port. I could have walked across the river without getting wet above the knee."

A study of the art object as performative

  • Description: My research project explores conventions in art-making and viewing via the notion of the performative art object. The performative (derived from J.L. Austin and Judith Butler’s formulations of the word) is here used predominantly as a term to denote a generative, experiential and iterative process (in this case outlined by art theorist Barbara Bolt) in which intuitive or playful actions of both artist and spectator dictate the route of research. The project, following an A/r/tographical cycle of theoriapraxis-poesis (or theory/research - doing/learning - art/making) as defined by Rita Irwin, thus investigates the relations inherent between artists, spectators or viewers, and objects, and how these may change according to the spaces they are conceived in; from art gallery to urban “non-art” environments. It deals with the inclusion of process or performativity within, or in relation to the art object and how this take on the traditionally static object may have the capacity to change how artworks are envisaged, and more significantly, how they are received, in terms of the effects they (in combination with the viewer) have on the world around them. Blurred in the context of performativity, the art object may become a means of documenting process and in a sense may act as a ‘prop’ for artistic research. This enquiry has involved the study of process and play, as related to creative practice, via a series of object-based events or interventions (including gallery exhibitions and other “non-art” events initiated by the artist outside of conventional art-related space) which have been documented and included in the theoretical research as a means of providing a first-hand narrative of theoretical ideas put into practice. Here Diana Taylor’s understanding of interrelated modes of storing and enacting knowledge as posed in the notion of the archive and repertoire has been utilised as a means of collecting and collating performative and ephemeral research. These events/interventions have further served as a means of gauging viewer interaction and participation, thus actively involving the viewer in the creative act. Jacques Rancière’s notion of the emancipated spectator is here utilised to activate the role of the viewer. In this regard, Martin Heidegger’s concept of handiness or handling serves as a means of “emancipating” spectators by encouraging tactile viewership. It is my intent to open up or reveal new modes of thinking or doing within the viewer when he or she enters a state of performative play within these events. Here the status of the art object is challenged and in this way has the potential to subvert or confront problematic repetitions, both in the identity of the viewer and the space occupied in each event.

  • Description: The treatment of Depressive Disorders in patients with chronic comorbid disease states warrants careful consideration of the risk-benefit ratio pertaining to the pharmacokinetic and pharmacodynamic characteristics of the antidepressant being considered, against the physiological susceptibilities of the patient; potential drug-drug interactions and depressive symptoms. The primary aim of this study was to investigate the relationship between Depressive Disorders and the most frequently diagnosed chronic comorbid disease states in a depressed South African study population; and to comment on the appropriateness of antidepressants prescribed to these patients. This retrospective drug utilisation study consisted of two parts: the first part focused on the prevalence of the most frequently diagnosed chronic comorbidities in a depressed South African population (N = 21 171). The three most prevalent chronic comorbid disease states were Hypertension (52.87 percent), Lipid Disorders (20.40 percent) and Arthritis (16.70 percent). The second part of the study included an assessment of the antidepressants prescribed to depressed patients in 2004 (N = 6 150). Emphasis was placed on the suitability of antidepressants selected for depressed adult patients (18 years of age and older) with comorbid Hypertension, Lipid Disorders or Arthritis. SSRIs were prescribed most frequently to the depressed patients during 2004 (59.67 percent). SSRIs are the suggested first-line treatments for depressed patients with multiple chronic comorbid disease states. However, of the SSRIs, fluoxetine has the least favourable pharmacokinetic profile and was found to be the antidepressant prescribed most often. Amitriptyline, which was the TCA prescribed most frequently, produces the greatest degree of anticholinergic, sedative and hypotensive effects, relative to other agents in the same antidepressant class. Thus, it is not recommended as a first-line antidepressant, especially in depressed patients with comorbidities. This study identifies potential areas of intervention regarding antidepressant prescribing in depressed individuals with chronic comorbid disease states and offers recommendations to promote the selection of optimal, individualised drug treatment strategies for these patients.

  • Description: This work reports on the conjugation of differently shaped Pt nanoparticles (PtNPs) with ClGa(III) 5,10,15,20-tetrakis-(4-carboxyphenyl) porphyrin (1) as well as chloro - (5,10,15,20-tetrakis (4- (4- carboxy phenycarbonoimidoyl) phenyl) porphyrinato) gallium(III) (2) The work also reports on platination of dihydroxosilicon octacarboxyphthalocyanine (OH)₂SiOCPc (3) to give dihydroxosilicontris(diaquaplatinum)octacarboxyphthalocyanine (OH)₂SiOCPc(Pt)₃ (4). The resulting conjugates were used for photodynamic antimicrobial chemotherapy against S. aureus, E. coli and C. albicans. The degree of photo-inactivation is dependent on concentration of the conjugates, light dose (fluence) and illumination time. The log reduction obtained for 1 when conjugated to cubic PtNPs was 4.64 log (which indicate 99.99 percent of the bacteria have been killed), which is much higher than 3.94 log unit for 1-hexagonal PtNPs and 3.31 log units for 1-unshaped PtNPs. Complex 2 conjugated to hexagonal PtNPs showed 18 nm red shift in the Soret band when compared to 2 alone. Complex 2 and 2-hexagonal PtNPs as well showed promising photodynamic antimicrobial chemotherapy (PACT) activity against S. aureus, E. coli and C. albicans in solution where the log reduction obtained was 4.92, 3.76, and 3.95 respectively for 2-hexagonal PtNPs. The singlet oxygen quantum yields obtained were higher at 0.56 for 2-hexagonl PtNPs in DMF while that of 2 was 0.52 in the same solvent. This resulted in improved PACT activity for 2-hexagonal PtNPs compared to 2. Complex 4 showed slight blue shifting of the absorption spectrum when compared to complex 3 The antimicrobial activity of 4 were promising as the highest log reduction value was observed when compared to the porphyrin conjugates.

  • Description: Size-fractionated chlorophyll-a (chl-a) concentrations and the in situ grazing rates of the copepods, Pseudodiaptomus hessei and Acartia longipatella, were assessed seasonally at the temporarily open/closed Kasouga estuary situated along the southeast coast of southern Africa. Total integrated chl-a concentration ranged between 1.17 and 12.18 mg chl-a m^(–3) and was always dominated by small phytoplankton cells (<20 μm), which comprised up to 86% (range 64–86%) of the total pigment. Total zooplankton abundance ranged between 2676 and 62 043 individuals m^(–3). These copepods numerically dominated the zooplankton counts, accounting for between 79% and 91% of the total. Gut pigment concentrations of the two species at night were significantly higher than the daytime values (P<0.05 in all cases). The observed pattern could be related to the marked diurnal vertical migration patterns exhibited by the copepods. Gut evacuation rates of P. hessei during the study ranged between 0.29 and 0.77 h^(–1) and between 0.39 and 0.58 h^(–1) for A. longipatella. The rate of gut pigment destruction for P. hessei and A. longipatella ranged between 55% and 81% and between 88% and 92% of the total chl-a ingested, respectively. The combined grazing impact of the two copepods ranged between 0.65 and 4.37 mg chl-a m^(–3), or between 4.3% and 35.9% of the available chl-a in the water column. Variations in the grazing activity of the two species could be attributed largely to seasonality in water temperature and shifts in the phytoplankton community structure and zooplankton abundance.

  • Description: It is common knowledge that the delivery of a high quality, well-resourced educational service to learners enrolled in state schools in the Eastern Cape has ground to a halt and this lack of service delivery has now become a pervasive problem. South African education has to a large extent failed to meet the needs of Black learners. Schools, like other contexts of childhood and adolescence are intimate places where youths construct identities, build a sense of self, read how society views them, develop the capacity to sustain relations and forge the skills to initiate change. These are the contexts where youth grow or shrink. Buildings in disrepair are not, therefore, merely a distraction; they are identity producing and selfdefining. There has been much debate on the topic of self-esteem and its relationship to school performance and academic achievement. Previous studies have highlighted that selfesteem and resilience do play a role in academic achievement. Despite the many challenges facing learners in under-resourced schools, many learners have overcome such challenges and achieved academic success. This study aimed to explore and describe the coping orientation and self-esteem of Black learners enrolled in under-resourced state schools in the Nelson Mandela Metropole. An exploratory, descriptive survey design was employed and eighty-five research participants completed the Orientation to Life Questionnaire 29 Item (OLQ 29 Item), Battle‟s Culture Free Self-Esteem Inventory Form AD (CFSEI Form AD) and a biographical questionnaire. Key findings revealed fairly high mean scores on the OLQ 29 Item and low total self-esteem scores. The General, Social and Personal self-esteem of the learners were found to be average. The results also revealed that learners with a high sense of coherence are likely to have high self-esteem; hence high sense of coherence is better explained by high self-esteem and low sense of coherence is better explained by low selfesteem.
