- Description: What is missing from abortion research is research that explores women’s narratives of the processes of abortion decision-making in a way that acknowledges the constraints placed on ‘choice’. This study sought to explore, using Foucauldian feminist post-structuralism and a narrative-discursive approach, women’s micro-narratives of the abortion decision-making process. Purposive sampling was used to recruit a total of 25 participants from three abortion facilities in the Eastern Cape. Participants were unmarried ‘Black’ women between the ages of 19 and 35, and were mostly unemployed. Narrative interviews were done with the women. Analysis revealed an over-arching narrative in which women described the abortion decision as something that they were ‘forced’ into by their circumstances. To construct this narrative, women justified the decision to have an abortion by drawing on discourses that normalise certain practices located within the husband-wife and parent-child axes and make the pregnancy a problematic, unsupported and unsupportable one. Gendered and generational power relations reinforced this and contributed to the obstruction of reproductive justice.

- Description: This study explored the methods available for measuring corporate sustainability and created an instrument to measure corporate sustainability in the Nelson Mandela Bay (NMB) automotive manufacturing sector. The instrument was created based on three components of sustainability which are environment, society and economy. The study went a step further and added a fourth dimension, current trends to design a measuring instrument. The instrument was then applied on participating companies and further refined to improve it. A total of 16 multi-dimensional indicators to measure corporate sustainability were created and applied to 12 companies in the automotive manufacturing sector. The indicators were used to create a composite corporate sustainability index which can be used to compare the corporate sustainability performance of companies. These indicators were created based on theoretical research and fist hand experience observing the automotive manufacturing sector in the NMB. The indicators were applied to companies as a pilot to test whether they are feasible. Following this, the indicators were refined, improved and applied to more companies to measure corporate sustainability performance. The results of the study were the measuring instrument created, the creation of a composite index as well as the application of the instrument on 12 companies to determine whether the instrument was refined enough to detect differences in the corporate sustainability performance of companies. The results are discussed and further recommendations are made for improvements in the creation and application of the instrument to measure corporate sustainability in the NMB automotive manufacturing sector.

- Description: South Africa has a high prevalence of infectious diseases; the major ones being the Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome epidemic, and tuberculosis. South Africa’s burden of resistant bacteria is also increasing. Antibiotic resistance in hospitalised patients leads to an increase in morbidity and mortality, resulting in longer hospital stays, and an increase in hospital costs. In order to counteract the problem of antibiotic resistance in hospitals and other healthcare facilities and preserve the efficacy of currently available antibiotics, there is a need for serious antibiotic management. Antibiotic stewardship initiatives have thus been put in place to guide healthcare professionals on the correct use of antibiotics. Clinical pharmacists can intervene and contribute to antibiotic stewardship owing to comprehensive knowledge of antibiotics, including the properties, uses, safety and efficacy of individual agents. There is a paucity of research to support the role of the clinical pharmacist in antibiotic stewardship in public sector hospitals. The current pharmacist staffing system within public sector hospitals does not adequately support pharmacists, in particular clinical pharmacists, to participate actively in antibiotic stewardship. The primary aim of the study was to evaluate the role of the clinical pharmacist in antibiotic stewardship in a public hospital setting. A secondary aim was to contribute towards more rational inpatient use of antibiotics in the general medical ward. The hypothesis for the study was that clinical pharmacists can make a positive contribution to the correct use of antibiotics in a public hospital setting. The study showed that the introduction of a pharmacist-driven antibiotic stewardship in the ward, using a prospective audit and feedback strategy, had a positive effect on overall appropriateness of antibiotic prescribing (Chi2=7.89; df=3; p=0.04815, Cramer’s V=0.13). However, this finding did not show any reduction in the volume of antibiotic use. Positive patient outcomes were achieved and shown through a reduction in the length of hospital stay (p=0.00487; one-way ANOVA). Although patients were not followed up on discharge to assess re-admission rates, the results are relevant in order to inform the hospital staff about the implementation of antibiotic stewardship at the public hospital setting with the aims of reducing inappropriate antibiotic prescribing and improving patient outcomes. From the results of the study, it can be concluded that the hypothesis was achieved and that the clinical pharmacist did play an integral role in antibiotic prescribing at the public hospital setting. Thus, it can be concluded that the study, though limited in its scope, achieved its aims and objectives, and showed that the clinical pharmacist does play an integral role in the rational use of antibiotics in a public hospital setting.

- Description: Publisher version , Traditional approaches to monitoring aquatic systems are often limited by the need for data collection which often is time-consuming, expensive and non-continuous. The aim of the study was to map the spatio-temporal chlorophyll-a concentration changes in Malilangwe Reservoir, Zimbabwe as an indicator of phytoplankton biomass and trophic state when the reservoir was full (year 2000) and at its lowest capacity (year 2011), using readily available Landsat multispectral images. Medium-spatial resolution (30 m) Landsat multispectral Thematic Mapper TM 5 and ETM+ images for May to December 1999–2000 and 2010–2011 were used to derive chlorophyll-a concentrations. In situ measured chlorophyll-a and total suspended solids (TSS) concentrations for 2011 were employed to validate the Landsat chlorophyll-a and TSS estimates. The study results indicate that Landsat-derived chlorophyll-a and TSS estimates were comparable with field measurements. There was a considerable wet vs. dry season differences in total chlorophyll-a concentration, Secchi disc depth, TSS and turbidity within the reservoir. Using Permutational multivariate analyses of variance (PERMANOVA) analysis, there were significant differences (p < 0.0001) for chlorophyll-a concentration among sites, months and years whereas TSS was significant during the study months (p < 0.05). A strong positive significant correlation among both predicted TSS vs. chlorophyll-a and measured vs. predicted chlorophyll-a and TSS concentrations as well as an inverse relationship between reservoir chlorophyll-a concentrations and water level were found (p < 0.001 in all cases). In conclusion, total chlorophyll-a concentration in Malilangwe Reservoir was successfully derived from Landsat remote sensing data suggesting that the Landsat sensor is suitable for real-time monitoring over relatively short timescales and for small reservoirs. Satellite data can allow for surveying of chlorophyll-a concentration in aquatic ecosystems, thus, providing invaluable data in data scarce (limited on site ground measurements) environments.

External interventions may therefore be perceived as supportive, fostering self-esteem and self-determination, while those perceived as controlling may have the opposite effect. A number of countries have adopted a strategy of rewarding tax compliance. The rewards range from certificates awarded to compliant taxpayers, to privilege cards providing opportunities for discounts or special treatment, to lotteries in which compliant taxpayers can participate. The reward strategies are often accompanied by publicity programmes. Two such hypothetical strategies were presented to participants in a survey conducted amongst small business owners in Ekurhuleni, South Africa, to gauge their responses.

- Description: This study investigates Educators‟ and learners‟ perceptions on English first additional language speakers‟ use of English as medium of instruction in two primary schools in the East London District. The study made use of a qualitative research method which includes interviews, observation and document analysis (learners‟ books). The uncovered data is analyzed against the background of the socio-economic and historical factors that led to this medium of instruction using content analysis (CA). After the apartheid regime in 1994 and the formation of a new government in 1996, the South African Constitution declared 11 languages in an attempt to encourage multilingualism in the country with each province having its provincial language policy. In the Eastern Cape where the study is conducted the language policy recognizes Xhosa, English, and Afrikaans as the official languages with English as the medium of instruction especially at the intermediate phase. The theoretical and conceptual framework for the study is provided by studies on language policy and planning, English as an international language, and Language as a mediating tool. The findings of the study indicate the crucial role that language of instruction plays in teaching and learning. However, challenges arise when the language of instruction is not the mother tongue. The study indicates dissatisfaction in the use of EMOI as a result of inadequate proficiency in the language of instruction, school environment, lack of resources; and lack of parental support. As a result of the above, some educators resorted to code switching when teaching. Hence, the study sheds light on EFAL learner‟s perspective on both comprehension and the level of educator‟s English skills and whether there is a connection between these two aspects. This resulted to conceivable methods that could be used to improve learner performance, teaching and learning methods and the efficiency of East London District support system. , Thesis (MEd) -- Faculty of Education, 2015

- Description: The subtropical forests located along South Africa’s Wild Coast region, declared as one of the biodiversity hotspots, provide benefits to the local and national economy. However, there is evidence of increased pressure exerted on the forests by growing population and reduced income from activities not related to forest products. The ability of remote sensing to quantify subtropical forest changes over time, perform species discrimination (using field spectroscopy) and integrating field spectral and multispectral data were all assessed in this study. Investigations were conducted at pixel, leaf and sub-pixel levels. Both per-pixel and sub-pixel classification methods were used for improved forest characterisation. Using SPOT 6 imagery for 2013, the study determined the best classification algorithm for mapping sub-tropical forest and other land cover types to be the maximum likelihood classifier. Maximum likelihood outperformed minimum distance, spectral angle mapper and spectral information divergence algorithms, based on overall accuracy and Kappa coefficient values. Forest change analysis was made based on spectral measurements made at top of the atmosphere (TOC) level. When applied to the 2005 and 2009 SPOT 5 images, subtropical forest changes between 2005-2009 and 2009-2013 were quantified. A temporal analysis of forest cover trends in the periods 2005-2009 and 2009-2013 identified a decreasing trend of -3648.42 and -946.98 ha respectively, which translated to 7.81 percent and 2.20 percent decrease. Although there is evidence of a trend towards decreased rates of forest loss, more conservation efforts are required to protect the Wild Coast ecosystem. Using field spectral measurements data, the hierarchical method (comprising One-way ANOVA with Bonferroni correction, Classification and Regression Trees (CART) and Jeffries Matusita method) successfully selected optimal wavelengths for species discrimination at leaf level. Only 17 out of 2150 wavelengths were identified, thereby reducing the complexities related to data dimensionality. The optimal 17 wavelength bands were noted in the visible (438, 442, 512 and 695 nm), near infrared (724, 729, 750, 758, 856, 936, 1179, 1507 and 1673 nm) and mid-infrared (2220, 2465, 2469 and 2482 nm) portions of the electromagnetic spectrum. The Jeffries-Matusita (JM) distance method confirmed the separability of the selected wavelength bands. Using these 17 wavelengths, linear discriminant analysis (LDA) classified subtropical species at leaf level more accurately than partial least squares discriminant analysis (PLSDA) and random forest (RF). In addition, the study integrated field-collected canopy spectral and multispectral data to discriminate proportions of semi-deciduous and evergreen subtropical forests at sub-pixel level. By using the 2013 land cover (using MLC) to mask non-forested portions before sub-pixel classification (using MTMF), the proportional maps were a product of two classifiers. The proportional maps show higher proportions of evergreen forests along the coast while semi-deciduous subtropical forest species were mainly on inland parts of the Wild Coast. These maps had high accuracy, thereby proving the ability of an integration of field spectral and multispectral data in mapping semi-deciduous and evergreen forest species. Overall, the study has demonstrated the importance of the MLC and LDA and served to integrate field spectral and multispectral data in subtropical forest characterisation at both leaf and top-of-atmosphere levels. The success of both the MLC and LDA further highlighted how essential parametric classifiers are in remote sensing forestry applications. Main subtropical characteristics highlighted in this study were species discrimination at leaf level, quantifying forest change at pixel level and discriminating semi-deciduous and evergreen forests at sub-pixel level.

Overall, the study has demonstrated the importance of the MLC and LDA and served to integrate field spectral and multispectral data in subtropical forest characterisation at both leaf and top-of-atmosphere levels. The success of both the MLC and LDA further highlighted how essential parametric classifiers are in remote sensing forestry applications. Main subtropical characteristics highlighted in this study were species discrimination at leaf level, quantifying forest change at pixel level and discriminating semi-deciduous and evergreen forests at sub-pixel level.

- Description: Alloyed quantum dots (QDs) passivated with shell materials have valuable optical characteristics suitable for a wide array of applications. In this work, alloyed ternary CdSeS QDs passivated with ZnSeTe and ZnSeTe/ZnS shells have been synthesized via a hot-injection method and a ligand exchange reaction employing L-cysteine as a thiol ligand has been used to obtain these water-soluble nanocrystals for the first time. The photoluminescence (PL) quantum yield (QY) of alloyed L-cysteine-capped CdSeS was 71.2% but decreased significantly to 5.2% upon passivation with a ZnSeTe shell. The red shift in PL emission of the CdSeS/ZnSeTe QDs was attributed to be strain-induced whilst a lattice-induced process likely created defect states in the core/shell interface hence contributing to the decline in the PL QY. Nonetheless, the fluorescence stability of CdSeS/ZnSeTe QDs in aqueous solution was unperturbed. Further passivation with a ZnS shell (CdSeS/ZnSeTe/ZnS) improved the PL QY to a value of 58.7% and thus indicates that the defect state in the QDs core/shell/shell structure was reduced. PL lifetime exciton measurements indicated that the rates of decay of the QDs influenced their photophysical properties.

- Description: The purpose of this study was to explore how teachers’ practice either supports or constrains learners’ conceptual understanding. The study is structured within an interpretive paradigm. The research takes the form of a case study and focused on the teaching practice of two purposefully selected teachers who had been identified as being effective/successful practitioners. The data was collected in two stages. In the first stage, qualitative data was collected by video recording six classroom lessons, three for each of the two participating teachers. In stage 2, participating teachers were individually interviewed. In these interviews the two participating teachers were asked to reflect on their classroom practice, through a process of stimulated recall, where their actions seemed to either support or constrain the development of learners’ conceptual understanding. The study identified a number of elements of the two teachers’ practice that related to the development of learners’ conceptual understanding in the classroom. These include building on learners’ prior knowledge, the use of concrete manipulatives, questioning that promotes critical thinking, and the use of multiple representations and connections. The study also identified elements of the two teachers’ practice that had the potential to constrain the development of learners’ conceptual understanding. These include the lack of opportunities for co-operative or peer-oriented learning, the absence of questioning that leads to discussion, and a scarcity of activities that build mathematical concepts through hands-on engagement. The study highlights the need for supporting teachers and helping them strengthen their practice with regard to those activities that support the development of conceptual understanding in their learners.

- Description: African Trypanosomiasis, which is caused by Trypanosoma brucei, is one of the crippling agents of social and economic development in Africa. T. brucei cycles between the cold-blooded insect vector, the tsetse fly (Glossina spp), and warm-blooded mammalian hosts. T. brucei, T. cruzi and L. major are mammal infecting kinetoplastid parasites that are collectively referred to as TriTryps. These parasites experience extreme environments as they move between their warm-blooded mammalian hosts and cold-blooded insect vectors which trigger extensive morphological transformations during the life-cycle of the parasite. Molecular chaperones have been implicated in parasite differentiation. TriTryps display significant expansions and diversity in the gene complements encoding molecular chaperones, especially J-proteins. Generally, J-proteins function as co-chaperones of Hsp70s, forming part of vital protein homeostasis processes. Hsp70s show a high degree of conservation, while J-proteins appear to be an extreme case of taxonomic radiation. Although several studies have focused on the molecular and cell biology of Hsp70s in some kinetoplastid parasites, knowledge is still lacking pertaining to J-proteins and their partnerships with Hsp70s. This thesis focused on the classification of kinetoplastid Jproteins into the four types by examining the domain organizations using T. brucei as a guide. The potential partnership of J-proteins and Hsp70s were postulated based on predicted subcellular localization. Kinetoplastid parasites, particularly T. brucei, have evolved an expanded and specialized J-protein machinery, likely to be a consequence of an evolutionary fitness/trait to adapt to diverse environment present in hosts and vectors. These analyses will yield insight into the process of parasite differentiation as well as provide new leads for chemotherapeutic treatments. The presence of the STI1 mediated Hsp90 hetero-complex formation has not been confirmed in T. brucei. To this end, in silico and biochemical techniques were used to characterize the role of TbSTI1, as an adaptor protein of Hsp70 and Hsp90. Through domain architecture analysis, sequence alignments, phylogenetic analysis and three-dimensional structure prediction, TbSTI1 was demonstrated to be the most conserved TPR containing co-chaperone of Hsp70 and Hsp83 in T. brucei and also shown to be highly similar to its eukaryotic homologues. Recombinant TbSTI1 was overproduced and purified in E.coli cells and subsequently shown to associate with TcHsp70 in a concentration dependent manner and associate weakly with TbHsp70.4. TbSTI1 and TbHsp83 were also demonstrated to be expressed and upregulated upon exposure to heat shock at the bloodstream stage of parasite development. In conclusion, this study is the first to report the interaction of TbSTI1 with a chaperone. Interactions between TbSTI1 and Hsp70s were demonstrated and therefore, the formation of the hetero-complex is predicted based the similarity of TbSTI1 to other STI1 proteins.

- Description: Academic libraries are not immune to conflict; various important external and internal factors underlie conflict. Change, both external and internal, leads to interpersonal conflict amongst librarians which is caused by differing goals, policies, rules and decisions. Technology has been the major change in the digital era and academic libraries embarking on meeting the needs of the users have to manage change. It is important to understand how change evolves in order to manage it and the faster the change, the more conflict can be expected. The main purpose of this study is to investigate change and conflict in library and information services. The study collected data from two selected academic libraries - Fort Hare and Walter Sisulu. The reason for this choice is that the two libraries are from the Eastern Border region and strategically located to serve the deep rural and poverty-stricken communities. Both libraries are from merged institutions, under-developed and faced with change and conflict. Data was gathered by means of a literature study and face-to-face, semi-structured interviews with six participants in each library: two librarians in senior, two middle management and two librarians occupying lower level positions. Purposive sampling was used to select participants who fit the criteria and who could contribute to the study. The findings reveal that library staff experience stress and conflict because of external and internal factors of change impacting the academic environment. The study generated important findings which are capable of guiding academic library management on how to manage change effectively in the „new‟ electronic environment. The findings show that understanding conflict also equips management with strategies and techniques to manage conflict effectively. This study offers valuable insights into the lived conflict experiences and perceptions of librarians and sheds much light on the role of conflict management in these environments. This study will contribute to the management of conflict in information services in university libraries and will be an innovative application of conflict theory to the library discipline.

- Description: Aim: To determine the level of knowledge and practice of the nurses in the prevention and control of nosocomial infection in the intensive care units and make recommendations aiming at bridging the gap identified. In this study, the level of knowledge and practice of nurses in the intensive care units was described and its relationship with the demographic characteristics was examined utilising a quantitative approach. A quantitative descriptive design was used to examine and describe knowledge and practices of intensive care nurses with regards to prevention and control of nosocomial infection. One hundred and thirty (130) nurses participated in the study taken from the intensive care units of the five (5) state hospitals of the Eastern Cape Province. A self-designed questionnaire with close-ended questions was utilised comprising of dichotomous questions, with ‘yes’ or ‘no’ measuring knowledge nurses have and a Likert scale that measured knowledge with regards to clinical practice utilised in the prevention and control of nosocomial infections. The following ethical considerations were addressed by the study: ethical clearance, permission to conduct the study, informed consent from participants, anonymity and confidentiality and respect of individual autonomy. Findings: The respondents showed encouraging agreement with the different practices that should be followed in order to prevent spreading of nosocomial infections in their units. This knowledge suggests that the problem of infection control in ICUs may be related to the individual characteristics of the profession as opposed to being institutional. Limitations: Not all the intensive care units of the Eastern Cape hospitals were included due to challenges of time, finance and geographic factors. Recommendations: The following recommendations were made: Orientation programme to all new staff coming into the ICUs including infection control policies and guidelines; Involvement of the ICU staff in the development of infection control policies so as to ensure ownership and ultimate compliance; The employer must ensure that all resources for infection control and prevention are available and accessible to the health care workers at all times to ensure compliance. , Thesis (MCur) -- University of Fort Hare, 2015

- Description: The development that has taken place in the health care sector includes all factors that have brought changes in the consumer decision-making process regarding the private health institutions. In Nigeria, the development is evident in the delivery of the health care services. This indicates that the private health institutions deliver quality health care service by using efficient and quality medical equipment. However, there is a growing awareness among clients to perform an extensive search before the purchase of health care service and the increased expectation from health care quality by clients and their family. The change in consumer behaviour has caused a shift in the consumer decision-making process due to the availability of several sources of information and various health institutions they can choose from. The purpose of this study is to investigate the factors that influence the consumer decision-making process that can enhance customer satisfaction and reduce cognitive dissonance. In this study the behaviour of consumers is related to how they make decisions along several stages before they make a purchase and in a health care setting the decision-making process refers to the process that clients pass through in making choices on alternative health institutions. The quantitative research method was adopted in this study in describing, analysing and interpreting data. A structured questionnaire was employed to collect primary data from 450 respondents in Lagos state, Nigeria. The primary data was statistically analysed using five stages, namely, exploratory factor analysis, Cronbach‟s alpha reliability testing, descriptive statistics, multiple regression analysis, and Pearson correlation analysis. The empirical results of this study indicates that service encounter experience, personal income and support sources are significantly related to the decision-making process. The decision-making process also has significant positive relationship with both customer satisfaction and cognitive dissonance. This indicates that influential factors that have been identified through the empirical results enlighten researchers and the private health institutions on issues that influence the clients‟ decisions to utilise private health institutions. The well-being and satisfaction of clients will be enhanced if the private health institutions can craft effective strategies that will enable clients to gain easy access and utilise health care services. This study emphasised that access to and utilisation of health care services in the private health institutions can be granted to clients through personal income and support sources from family members and private health institutions. Futhermore, health insurance coverage is an effective way that will help clients overcome the financial constraints and restricted access to and utilisation of private health institutions. The study further reveals that the well-being and satisfaction of clients will be enhanced if private health institutions improve access to quality health care. Failure to improve the overall quality and performances of the health care services in the private health institutions can lead to clients‟ cognitive dissonance. Both private and public health institutions should play a major role in providing the necessary facilities that can assist the clients in their decision-making process regarding their health care needs. This will enable the health care institutions‟ staff to understand what clients value and need and, therefore, how well to satisfy them and reduce cognitive dissonance. Easy access and utilisation of the private health institutions as well as satisfaction in quality health care delivery will create better health outcomes for the workforce and citizens of a country and this will improve economic development.

- Description: Clausena anisata (Willd) Hook, is the only species out of the 15 species of the genus found in the African continent and is regarded as a threatened species in this area of Southern region of Africa. Its distribution spread across Africa to south-east Asia. C. anisata has a wide range of ethno-pharmacological importance. Despite the numerous studies on the pharmacological profile of the plant, there is still dearth of scientific literature on the foliar micro-morphology of this valuable medicinal plant. The morphorlogical structure of the leaves of C. anisata was examined under Light Microscopy (LM), Scanning Electron Microscopy (SEM) and Energy Dispersive x-ray Spectroscopy (EDS) following standard procedures. LM indicates the types of stomata of the leaves (amphistomatic). SEM revealed the presence of the whip like trichomes with its uniqueness to the plants. EDS showed the chemical composition of the foliar appendages which indicated the presence Ca, Mg, S, and Fe. The indication of the elements could probably be helpful in the herbal drug regulation based on the mineral composition and in return reduced herbal drug toxicity.

EDS showed the chemical composition of the foliar appendages which indicated the presence Ca, Mg, S, and Fe. The indication of the elements could probably be helpful in the herbal drug regulation based on the mineral composition and in return reduced herbal drug toxicity.

- Description: It is estimated by the World Health Organization (WHO) that by 2040 neurodegenerative disorders will collectively surpass cancer as the primary cause of death in industrialised countries (WHO,2006). Natural flora represents one of the most important therapeutic sources in modern drug discovery, however only a limited number of plant species have been screened for their neuroprotective value. The neuroprotective potential of eleven Algerian and two South African medicinal plant extracts were assessed in this study, aiming to identify promising candidates for future research. Neurodegenerative disorders such as Parkinson’s disease are characterised by distinct biochemical features, including protein misfolding/-aggregation, excessive oxidative stress and apoptotic cell death. As such, medicinal plant extracts were screened for biological properties directly relevant to neurodegeneration. The capacity to induce autophagy was also investigated as mounting evidence suggests that activation of this pathway may reduce abnormal protein aggregation and promote neuronal survival.

- Description: The primary aim of this thesis is to interrogate existing psychoanalytical theory, as well as to conduct research on ‘the Burtonesque’ in order to examine two of Tim Burton's filmic adaptations of classic literary works for children, namely: Alice in Wonderland (2010), an adaptation inspired by Lewis Carroll's Alice books, and Charlie and the Chocolate Factory (2005), based on Roald Dahl's novel of the same title. Firstly, the chapters will explore the psychological elements found in the original texts, which Burton amplifies in his onscreen adaptations by means of various stylistic and thematic techniques that have become known as ‘the Burtonesque’. Secondly, the ‘Burtonesque’ itself will be explored, and thirdly, by means of comparative analysis, the investigation will focus on the manner in which such aesthetics aid Burton in highlighting psychological concerns in his films, as well as interrogate his cinematic alterations to existing texts in order to further his purpose. As a keen enthusiast of psychology and having won awards within the field, Tim Burton, a foremost contemporary Hollywood filmmaker, in his adaptations of children’s classics, deliberately magnifies the psychoanalytic components that are often found in the tales. Through his unique interpretation, Burton brings the psychoanalytic approach to children’s stories to a new level. He explores certain themes such as death, childhood fantasies, psychological development and parental relationships, and makes use of specific artistic techniques that create a sense of the uncanny and defamiliarisation in the viewer. Due to his gothic cinematic approach, Burton is one of the most recognisable artists in his field, with a consistent vision that is concerned with cinematic and thematic aspects of his work, branding his films with a unique ‘Burtonesque’ quality that has become instantly identifiable. As a result of Burton’s psychological interest in children’s stories, Tim Burton’s film adaptations of the Dahl and Carroll classic children’s stories can be interrogated under a psychoanalytic lens. Psychoanalytic literary criticism is a method of literary analysis that is informed by the tradition of psychoanalysis established by Freud. In Burton scholarship, critical exploration should take the form of not only a close reading of the original text and analysis of the film version in order to come to a psychoanalytic interpretation, but by means of comparison of film and text, highlight the methods applied by psychoanalytic theory. A close comparative analysis of original literary works by Roald Dahl and Lewis Carroll, and Tim Burton’s filmic adaptations will be conducted in this study. Thereby, the manner in which Tim Burton employs specific techniques in order to emphasise the stories’ psychological components will be explored. Biographical information of Dahl and Lewis, as well as a short synopsis of their stories will be included in order to provide the context for psychoanalytical criticism. A discussion of ‘the Burtonesque’ will be provided, as well as a brief exploration of his adaptation history and Burton’s specific interest in psychology. Research methods to be applied in the analysis of the original texts and their film versions are psychoanalytic literary theory, drawing predominantly on the work of theorists: Sigmund Freud, Jacques Lacan and Carl Jung. A close examination of auteur theory, the unique voice Burton has established through his iconic cinematic techniques, now coined ‘the Burtonesque’, will also be applied to provide a fuller and rounder interrogation. The focus of this project is to investigate thempsychoanalytical elements found in the texts and films, in order to clearly illustrate how Tim Burton’s cinematic approach serves to highlight a psychoanalytic interpretation.

- Description: Polyurethane composite adsorbent polymeric material was prepared and investigated for selected solid-phase extraction for metal ions, prior to its determination by inductively coupled plasma optical emission spectrometry. The surface characterisation was done using Fourier transform infrared spectroscopy. The separation and preconcentration conditions of the analytes investigated includes influence of pH, sample loading flow rate, elution flow rate, type and concentration of eluents. The optimum pH for the highest efficient recoveries for all metal ions, which ranged from 70 to 85 %, is pH 7. The metal ions were quantitatively eluted with 5 mL of 2 mol/L HNO3. Common coexisting ions did not interfere with the separation. The percentage recovery of the metal ions ranged between 70 and 89 %, while the results for the limit of detection and limit of quantification ranged from 0.249 to 0.256 and 0.831 to 0.855, respectively. The experimental tests showed good preconcentration results of trace levels of metal ions using synthesised polyurethane polymer adsorbent composite.

- Description: This research investigated the impact of decentralisation on participatory development in the Nsanje District of Malawi from 2009 to 2014. Existing challenges in realising effective participation were identified by acquiring information from documents at three spheres of government, namely local, district and national. The literature explains decentralisation and local government; the theories of state-local relations; the nature, types and determinants of participation; the legislative framework of local government; and decentralisation reforms being implemented in Malawi. A descriptive approach was used in the study, with the emphasis on collecting data from primary sources such as minutes, reports, newspapers, and secondary sources such as the District Council and local government department records, books, academic journals, completed and unpublished post-graduate research theses, and legislation. From the acquired information, a number of recommendations are made to deal with various challenges faced to achieve effective participatory development in the District.
