- Description: It was hypothesised that there would be behavioural consistencies in the offences of South African serial killers. The themes underlying these observable differences can help us understand the nature of these offences. Crime scene data was ohtained from police records, and structured, in-depth offender interviews. 73 offences, committed by 13 offenders, were analysed. The analysis used Smallest Space Analysis (SSA), a Multidimensional scaling (MDS) procedure. This analysis revealed systematic patterns of behaviour in the offences. It was found that the focus of these offences is an impersonal, hostile, and act-focused murder were the victim is treated as a depersonalised object. Empirical support for an underlying thematic structure to these offences was also provided. The offence themes identified relate to the nature of the actions committed during the offence, and the function these actions had for the offender. These fmdings thus support the hypothesis that these offences will display meaningful behavioural variation. These findings have direct utility in the investigation and study of serial killing in South Aflica. They also provide the basis for comparison with previously suggested typologies of serial killing, and indicate directions for future research into this phenomenon in the South African setting. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This study was conducted in one of the education districts in the Eastern Cape Province of South Africa. The purpose was to analyse the effectiveness of the concrete/semi-concrete/abstract (CSA) approach and drill-practice instructional strategies on Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions. The following two objectives were set. First, to identify the learners’ challenges in studying addition and subtraction of algebraic fractions in grade 10; and second to analyse the effectiveness of the CSA approach and drill-practice instructional strategies on Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions. Both threshold concepts and troublesome knowledge, Polya’s problem-solving techniques, CSA Approach theory and Drill-practice theory were all pertinent as a theoretical framework for the study. Positivism research paradigm was adopted for the study and it afforded the researcher opportunity to employ quantitative research approach. Based on the research question of this study, an experimental design was chosen as a suitable descriptive design. Purposive sampling method was used to select three schools which involved 135 grade 10 mathematics learners. Stratified random sampling method was thereafter employed to select 45 learners from each school for the study. The learners were grouped in each school as top, average and weak based on their performance in Algebra in term one. Pre-questionnaire and post-questionnaire were used to obtain data regarding challenges learners experience in simplifying addition and subtraction of algebraic fractions. Ethical clearance from the relevant school and university authorities were obtained. On the first two days, the researcher briefed the school authorities and learners and explained to them the purpose and details of the study. Day three was used to administer the pre-questionnaire test, thereafter, the next ten days were used to teach addition and subtraction of both numeric and algebraic fractions with same and different numerators and denominators. The next two days were used for revision and the last day was used to administer the postquestionnaire test out 25 marks. The respondent rate was 98.5%. The data collected were analysed by using SPSS version 16.10. Both descriptive and inferential statistics were used to analyse the data. The pre-questionnaire scores revealed that majority of the learners’ perceived fractions as two separate entities and as a result add or subtract numerator to numerator and denominator to denominator. It was also discovered that learners had a challenge in finding LCM of algebraic fractions. A t-Test for independent means was used to test the following hypotheses at 𝛼 = 0.05: 𝐇𝟎: The CSA approach and drill-practice intervention has no significant effect on Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions; 𝐇𝟏: The CSA approach and drill-practice will significantly enhance Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions. The t-Test revealed a p-value of 0.139 which was statistically significant at 𝛼 = 0.05. Therefore, the researcher rejected the null hypothesis and concluded that the CSA approach and drill-practice have significantly enhanced the Grade 10 learners’ ability to simplify algebraic fractions.

- Description: Portulacaria afra commonly known as Spekboom contributes significantly to carbon sequestration and has been widely planted in degraded areas of the Eastern Cape. Approximately 50% of planted cuttings do not survive although the cause of this decline is unknown. Like many indigenous plants, Spekboom forms a symbiotic relationship with mycorrhizal fungi and the interaction with rhizobacteria may enhance and improve plant growth and establishment. This study aims to investigate these relationships which will include a survey of the arbuscular mycorrhizal (AM) fungal populations associated with Spekboom, determination of the causal agent of Spekboom decline, isolation and identification of the associated rhizobacteria and investigation of their plant growth promotion properties and assessing the ability of arbuscular mycorrhizal fungi and selected rhizobacteria to enhance establishment and growth of Spekboom. Soil and root samples from selected trial sites were used to assess AM fungal spore abundance and colonisation; isolation, characterization, and identification of rhizobacteria and determine the interaction of the microbes on Spekboom growth and tolerance to Fusarium. AM spore abundance and percentage root colonisation did not differ between the three Spekboom plots. Molecular analyses of the SSU region from the plots showed 4 families of AM fungi and were identified as Ambisporaceae, Glomeraceae, Claroideoglomeraceae and Paraglomeraceae. A suspected Fusarium pathogen was isolated and molecularly identified. Pathogenicity tests indicated reduced Spekboom growth with poor root development. Thirty four rhizobacterial isolates were tested for various plant growth promoting abilities. Of these, 6 were able to produce IAA which may promote plant root growth, 27 siderophores and 23 were phosphate solubilisers. Bacterial isolates were molecularly identified to be from various species of Bacillus, with some Arthrobacter, Enterobacter, Pseudomonas and Microbacterium. Inoculation of Spekboom cuttings with mycorrhizal fungi and selected rhizobacterial isolates significantly improved shoot height. Spekboom cuttings challenged with Fusarium and inoculated with mycorrhizal fungi and two rhizobacterial isolates significantly improved growth. The inoculation of cuttings in the nursery with mycorrhizal fungi and selected rhizobacteria is recommended prior to establishing Spekboom in the field.

- Description: This research examines the plausibility of developing demand forecasting techniques which are consistently and accurately able to predict demand. Time Series Techniques and Artificial Neural Networks are both investigated. Deodorant sales in South Africa are specifically studied in this thesis. Marketing techniques which are used to influence consumer buyer behaviour are considered, and these factors are integrated into the forecasting models wherever possible. The results of this research suggest that Artificial Neural Networks can be developed which consistently outperform industry forecasting targets as well as Time Series forecasts, suggesting that producers could reduce costs by adopting this more effective method.

- Description: In contrast with the large number of poorly performing schools in Swaziland over the past decade (1991-2000), a few schools have managed to attain consistently good results. One such school is St Michael's High. This study draws on the perceptions of different major stakeholders at St Michael's of factors deemed to have contributed to academic success at the school. The study thus follows Fertig (2000), who advocates research in effective schools to be done by looking at the perceptions of different stakeholders rather than in relation to an objective checklist. In this study, St Michael's High is found to be an effective school. Its experience can play a vital role in helping other ineffective and failing schools to improve their academic standing and tarnished public image, provided the schools unreservedly commit themselves to changing their ways. This investigation is aimed at understanding the roles which the school leadership and associated stakeholders have played in making St Michael's an exemplary school in Swaziland. Its findings indicate that the schools that themselves take the initiative to improve their effectiveness are the ones which are successful, which accords with the consensus in research literature on school effectiveness. The evidence gathered in this study suggests that St Michael's is characteristic of such effective schools. Since this is a qualitative interpretive case study on perception of success factors in a girls' high school within the city of Manzini, interviews comprising semi-structured questions were highly useful in tapping the understanding of how various stakeholders contribute to the academic achievement of students in the school. The findings, organised in the form of themes, help illuminate what appears to be a systematic and well-focussed approach toward the academic development of the school and the fulfilment of its goals. Every aspect of the school system is thoroughly explored. The validity of the stakeholders' claim that St Michael's High is a dream school for most Swazi children is verified by the school's examination results for the past decade. But what the research reveals are the cultural, academic, social, and moral values and beliefs which serve as a strong anchor for the school leadership and management, and without which St Michael's as an organisation would be unable to meet the challenge of implementing academic and national reconstruction.

- Description: Parental Alienation Syndrome (PAS) is a childhood disorder that arises almost exclusively in child custody disputes. Its primary manifestation is the unjustified rejection of a once-loved parent by a child due to a combination of the 'programming' parent's alienating techniques and the child's own contributions to the vilification of the targeted parent. Parental Alienation (PA) is differentiated from PAS as in the case of the former the child's rejection is justified and may be explained either by normal developmental behaviours or by child abuse that involves no form of programming. The purpose of this study is to develop a preliminary interview protocol to aid in the detection of PAS, with a special emphasis on differentiating false allegations of abuse, which usually accompany severe PAS, from true abuse. The aim of the study is to develop a protocol to enhance diagnostic clarity and facilitate appropriate custody-related recommendations. The interview protocol is based on an extensive thematic literature analysis in conjunction with existing guidelines for conducting a child custody and visitation interview. The interview protocol comprises a child and parent section, which both have their own reference tables with supporting corresponding information. The protocol 's administration instructions are outlined in a covering information page. Rigour was added to the protocol by having it assessed for clarity and accessibility by four medico-legal professionals with custody-related experience, and their opinions regarding the protocol's structure, sections, questions and reference tables were taken into consideration in the revision of the protocol. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: .M. Coetzee’s The Lives of Animals (1999) is a literary representation of, and intervention into, human-animal relations. It is an experimental literary destabilisation of the generic boundaries that underlie the systematic (mis)representation and (mis)treatment of nonhuman animals, specifically their mass commodification in contemporary societies. The text provides a critique and negotiation of anthropocentric reason and its ramifications for nonhuman animals. This study focuses on how Coetzee’s narrative problematises dominant discourses through questioning their authority and offering alternatives to anthropocentric conceptions of the animal that are based upon reason-centred and dualistic thought. The duality of human versus animal is explored alongside other dualities deconstructed in the text, such as fiction versus nonfiction, and philosophy versus literature. Coetzee’s representation of these constructs and their interconnectedness is investigated, specifically with regards to positively developing human-animal relations. Through exploring what Coetzee calls the ‘sympathetic imagination’, his alternative contribution to the field of human-animal relations will be considered. This study focuses on the space for re-imagination that Coetzee has provided with The Lives of Animals. It highlights the role literature can and ought to play in this re-imagination, and why this re-imagination is necessary for the development of human-animal relations. Posthumanism will be used as a theoretical lens throughout, as it appears to resonate closely with Coetzee’s project. Both the form and the content of the text will be analysed, highlighting their interconnected significance in Coetzee’s project and the continued relevance of interventions such as this.

- Description: This research investigates the relationship between employee performance, leadership and emotional intelligence in a South African parastatal. The literature provided discusses the three variables of performance, leadership and emotional intelligence. Information was gathered, using three instruments, from a sample of 160 leaders and 800 raters. The Multifactor Leadership Questionnaire was used to determine leadership style within the parastatal, while the Emotional Competency Profiler was used to determine the emotional intelligence of the leaders within the parastatal. Employee performance was captured and recorded using the parastatal’s performance appraisal process. Leadership and emotional intelligence were identified as the independent variables and employee performance as the dependent variable. Data obtained from each of the research instruments was then statistically analysed. Through linear regression analysis it was concluded that there is a significant relationship between employee performance and an emotionally intelligent, transactional leader. However, no significant linear relationship was found between employee performance and an emotionally intelligent, transformational leader. Simple correlation analysis showed that there is a relatively weak significant linear relationship between emotional intelligence and transactional leadership. Moreover, it was found that there is a very strong significant linear relationship between emotional intelligence and transformational leadership. This research therefore adds a new dimension to employee performance, leadership and emotional intelligence, since no similar study has been conducted. As this research takes place in the South African context, it contributes to the bank of findings relating to the concepts.

Simple correlation analysis showed that there is a relatively weak significant linear relationship between emotional intelligence and transactional leadership. Moreover, it was found that there is a very strong significant linear relationship between emotional intelligence and transformational leadership. This research therefore adds a new dimension to employee performance, leadership and emotional intelligence, since no similar study has been conducted. As this research takes place in the South African context, it contributes to the bank of findings relating to the concepts.

- Description: This thesis explores the thematic desire to establish an ecological human bond with nature in four contemporary novels: The English Patient by Michael Ondaatje, The Hungry Tide by Amitav Ghosh, An Imaginary Life by David Malouf, and The Expedition to The Baobab Tree by Wilma Stockenström. These authors share a concern with the influence that language has on human perception, and one of the most significant ways they attempt to connect with the natural world is through somehow escaping, or transcending, what they perceive to be the divisive tendencies of language. They all suggest that human perception is not steered entirely by a disembodied mind, which constructs reality through linguistic and cultural lenses, but is equally influenced by physical circumstances and embodied experiences. They explore the potential of corporeal reciprocity and empathy as that which enables understanding across cultural barriers, and a sense of ecologically intertwined kinship with nature. They all struggle to reconcile their awareness of the potential danger of relating to nature exclusively through language, with a desire to speak for the natural world in literature. I have examined whether they succeed in doing so, or whether they contradict their thematic suspicion of language with their literary medium. I have prioritised a close ecocritical reading of the novels and loosely situated the authors’ approach to nature and language within the broad theoretical frameworks of radical ecology, structuralism and poststructuralism. I suggest that these novels are best analysed in the context of an ecocritical mediation between poststructuralist conceptions of nature as inaccessible cultural construct, and the naïve conception of unmediated, pre-reflective interaction with the natural world. I draw especially on the phenomenological theories of Maurice Merleau-Ponty, whose insistence that perception is always both embodied and culturally mediated truly renders culture and nature irreducible, intertwined categories. By challenging historical dualisms like mind/body and culture/nature, the selected novels suggest a more fluid and discursive understanding of the perceived conflict between language and nature, whilst problematizing the perception of language as merely a cultural artefact. Moreover, they are examples of the kind of literature that has the potential to positively influence our human conception of nature, and adapt us better to our ecological context on a planet struggling for survival.

- Description: The Lake Mentz and Kommadagga Subgroups were deposited in a marine environment and are characterised by a heterogeneous sequence of sediments, which range in grain size from clays to grits. During the first phase of deposition the Kweekvlei Shale and Floriskraal Formations were deposited in a prograding shoreline environment, whereas the succeeding Waaipoort Shale Formation is interpreted as represnting a reworked shoreline . The final phase of deposition of the Cape Supergroup was a regressive one in which the Kommadagga Subgroup was formed. The coarsening upward cycle of this subgroup represents a deltaic deposit. A significant time gap appears to exist before the deposition of the glacial-marine Dwyka Tillite Formation. Structurally, the area was subjected to deformation by buckle folding at about 250 Ma into a series of folds with southward dipping axial planes. Only one phase of deformation is recognised in the study area . A decrease in pore space, mineral overgrowths,formation of silica and calcite cements and development of autigenic minerals such as opal, stilpnomelane, analcite, prehnite, muscovite and various clay minerals are the characteristic diagenetic features of the sediments. The mineralogical evidence suggests that the maximum temperature and pressure of burial was 150 C and 4 to 5 Kbar respectively.

- Description: The South African Global Navigation Satellite System (GNSS) network of dual frequency receivers provide an opportunity to investigate solar cycle effects on ionospheric Total Electron Content (TEC) over the South Africa region by taking advantage of the dispersive nature of the ionospheric medium. For this task, the global University of New Brunswick Ionospheric Modelling Technique (UNB-IMT) was adopted, modified and applied to compute TEC using data from the southern African GNSS Network. TEC values were compared with CODE International GNSS services TEC predictions and Ionosonde-derived TEC (ITEC) measurements to test and validate the UNB-IMT results over South Africa. It was found that the variation trends of GTEC and ITEC over all stations are in good agreement and show pronounced seasonal variations with high TEC values around equinoxes for a year near solar maximum and less pronounced around solar minimum. Signature TEC depletions and enhanced spikes were prevalently evident around equinoxes, particularly for a year near solar maximum. These observations were investigated and further discussed with an analysis of the midday Disturbance Storm Time (DST) index of geomagnetic activity. The residual GTEC – ITEC corresponding to plasmaspheric electron content and equivalent ionospheric foF2 and total slab thickness parameters were computed and comprehensively discussed. The results verified the use of UNB-IMT as one of the tools for ionospheric research over South Africa. The UNB-IMT algorithm was applied to investigate TEC variability during different epochs of solar cycle 23. The results were investigated and further discussed by analyzing the GOES 8 and 10 satellites X-ray flux (0.1 – 0.8 nm) and SOHO Solar Extreme Ultraviolet Monitor higher resolution data. Comparison of UNB-IMT TEC derived from collocated HRAO and HARB GNSS receivers was undertaken for the solar X17 and X9 flare events, which occurred on day 301, 2003 and day 339, 2006. It was found that there exist considerable TEC differences between the two collocated receivers with some evidence of solar cycle dependence. Furthermore, the daytime UNB TEC compared with the International Reference Ionosphere 2001 predicted TEC found both models to show a good agreement. The UNB-IMT TEC was further applied to investigate the capabilities of geodetic Very Long Baseline Interferometry (VLBI) derived TEC using the Vienna TEC Model for space weather monitoring over HartRAO during the CONT02 and CONT05 campaigns conducted during the years 2002 (near solar maximum) and 005 (near solar minimum). The results verified the use of geodetic VLBI as one of the possible instruments for monitoring space weather impacts on the ionosphere over South Africa.

It drew on perspectives from cultural studies, the constructionist approach to representation and the sociology of news production. Through the use of the quantitative and qualitative research methods, content analysis and critical discourse analysis, this study established first, that few significant changes have occurred within the newspaper's coverage of the MDGs during this period, and second, that the people most affected by the MDGs and affiliated programmes are seriously under-represented and that the manner of representation marginalises and subordinates them.

- Description: This study sought to investigate the access to information about social grants by the elderly population of Balfour village in Raymond Mhlaba Local Municipality in SA’s Eastern Cape Province. A study on access to information is quite relevant in the knowledge-based economies. People act when they have information and similarly elderly people require information in order to access their grants. This study is quite relevant in the Library and Information Science field. The targeted population for the study were the elderly people of the Balfour village. The qualitative research approach was used in this study. The researcher selected a sample for the study using snowballsampling procedure. Both in-depth interviews and questionnaires were employed as methods of gathering data and thematic analysis of data was used. Results showed that there is a lack of information dissemination and access to information about social grants for elderly people living in Balfour. The study found out that elderly people in Balfour complained that, in most cases, they were not sure about the documents they were supposed to bring with them when they visited the South African Social Security Agency offices. This indicates the need for SASSA to train their staff members to be customer orientated and encourage staff to empower themselves with formal educational qualifications. In addition, the distance to and from SASSA offices is of great concern because elderly people spend significant amounts of money for travelling these distances. Therefore, there must be an office that is situated in a favourable distance to the elderly so that they do not struggle when they want to reach SASSA offices. Another option would be to avail a mobile office that may serve the area two or three times a week.

- Description: This study conducted an explanatory sequential research on local municipalities in Amathole District‘s social media use for participatory water conservation education in South Africa. Social media is regarded as a powerful tool for information dissemination, because of its incredible speed, storage capacity, and communicative ability. However, it was worth finding out if social media platforms were being utilised fully to educate communities about water conservation by these municipalities. The South African government invests in water conservation interests through legislation and prescribes that municipalities, as local governance at the grassroots level, supply water and sanitation according to national norms and standards. With reference to this, municipalities have to educate about water conservation. The prevailing water scarcity in South Africa calls for increased education and awareness creation about water conservation to communities and municipalities have to use this opportunity by using social media. Therefore, the research aimed to know if social media platforms were being used as a tool for participatory water conservation education in Amathole District‘s local municipalities. This study used purposive sampling for data collection. The first data set was collected from the local municipalities‘ social media platforms and qualitative content analysis was used for analysis to find out if the municipalities used social media for water conservation education. The second data set aimed at getting residents‘ perception towards social media use for participatory water conservation education by their municipality was collected from 383 respondents in Raymond Mhlaba Local Municipality using a questionnaire. The data from the questionnaire was analysed quantitatively using Statistical Package for Social Sciences (SPSS). The study found out that Amathole District local municipalities were not using social media for water conservation education. Most respondents from Raymond Mhlaba Local Municipality indicated lack of knowledge of their municipality‘s social media presence, while the few who were aware of the social media platforms rarely communicated with the municipality. Hence, the study recommends that municipalities should advertise their social media platforms and use them for developmental and beneficial purposes such as water conservation education.

- Description: In this study an analysis of the long-term equilibrium relationship between economic growth measured as real GDP growth and private capital inflows is explored. The link between private capital inflows and economic growth is well-documented in the literature. However, a void in the literature relates to examining the cointegrating relationship between private capital inflows and economic growth particularly for South Africa. It is widely claimed that private capital inflows foster economic growth by closing the savings/investment gap. However, clarity on this point is necessary because of the seemingly unclear nature of the relationship in the literature. The exact form of this relationship as well as the nature of capital flows that could impact on real growth requires further investigation. Moreover, what exactly happens to this relationship in an economic crisis such as recently recorded in the global financial crisis is not clear. The analysis is undertaken by employing cointegration and vector error correction modeling approach using quarterly data for the period 1989q4-2009q4. This study employs the Johansen (1998) cointegration test. This technique distinguishes itself since it establishes the long run relationship between variables. Thereafter, residual diagnostic checks are performed on the variables. Our results show among others, that private capital inflows have impacted positively on the growth of the South African economy. The areas for further research that emerge from this study include the effect of some government policies on economic growth that should also receive more attention in the future since political instability slows down investment.

- Description: This research explores the use of the versatile 4,4-difluoro-4-boro-3a,4a-diaza-s-indacene (BODIPY) dyes and the modification of their spectroscopic properties. The synthesis of a tetramethyl-BODIPY bearing a sterically hindered meso-phenyl ring with an ethynyl functional group at the para-position was compared to that of its freely rotating counterpart with no methyl substituents on the BODIPY core, with the fluorescence properties in particular proving to be markedly different. These phenyl-ethynyl-substituted BODIPYs were used as the starting materials for the synthesis of novel BODIPY dyes for sensor applications via Sonogashira coupling reactions at the ethynyl position, but this resulted instead in the serendipitous synthesis of a novel BODIPY dimer in which the para-positions of the meso-phenyl rings are linked by a diethynyl bridge. Following iodination at the 2, 6-positions, the dimer was found to have a singlet oxygen quantum yield of 0.88, compared to the value of 0.86 that was obtained for the analogous monomer. Since the εmax values for the main spectral bands of the dimers are significantly higher, the compounds may be of interest for singlet oxygen generation applications. A second study was carried out on the interaction between methyl ester functionalized BODIPY dyes and upconversion nanoparticles (UCNPs) to explore the possible use of BODIPY-UCNP conjugates in biomedical applications. The singlet oxygen generation properties of the BODIPY were tested following iodination at the 2, 6-positions, a singlet oxygen quantum yield value of 0.86 was obtained. Three sets of oleate capped UCNPs were synthesized with different diameters and were rendered water dispersible with the addition of a silica shell. The necessary scaffolding for conjugation to the BODIPY was provided by amine groups following functionalization of this shell. All of the sets of oleate capped and silica coated UCNPs were characterized by transmission electron microscopy (TEM) and X-ray diffractometry (XRD) and their emission properties were studied upon excitation at 978 nm with a diode laser with a Picoquant Fluotime 300 spectrophotometer that enables the measurement of anti-Stokes emission. The potential utility of UCNP-BODIPY conjugates for singlet oxygen applications, such as PDT, was then assessed.

These phenyl-ethynyl-substituted BODIPYs were used as the starting materials for the synthesis of novel BODIPY dyes for sensor applications via Sonogashira coupling reactions at the ethynyl position, but this resulted instead in the serendipitous synthesis of a novel BODIPY dimer in which the para-positions of the meso-phenyl rings are linked by a diethynyl bridge. Following iodination at the 2, 6-positions, the dimer was found to have a singlet oxygen quantum yield of 0.88, compared to the value of 0.86 that was obtained for the analogous monomer. Since the εmax values for the main spectral bands of the dimers are significantly higher, the compounds may be of interest for singlet oxygen generation applications. A second study was carried out on the interaction between methyl ester functionalized BODIPY dyes and upconversion nanoparticles (UCNPs) to explore the possible use of BODIPY-UCNP conjugates in biomedical applications. The singlet oxygen generation properties of the BODIPY were tested following iodination at the 2, 6-positions, a singlet oxygen quantum yield value of 0.86 was obtained. Three sets of oleate capped UCNPs were synthesized with different diameters and were rendered water dispersible with the addition of a silica shell. The necessary scaffolding for conjugation to the BODIPY was provided by amine groups following functionalization of this shell. All of the sets of oleate capped and silica coated UCNPs were characterized by transmission electron microscopy (TEM) and X-ray diffractometry (XRD) and their emission properties were studied upon excitation at 978 nm with a diode laser with a Picoquant Fluotime 300 spectrophotometer that enables the measurement of anti-Stokes emission. The potential utility of UCNP-BODIPY conjugates for singlet oxygen applications, such as PDT, was then assessed.

- Description: Trusts are subject to multiple forms of legislative regulation dealing with taxation and governance. Trusts were widely used by planners as tax avoidance shelters. Tax legislation was amended to subject trusts, other than special trusts as defined, to the highest income tax rate of forty percent, in terms of section 5(2) of the Income Tax Act, 58 of 1962. The inter vivos trust is also subject to a wide range of anti-avoidance measures, including those contained in sub-sections (3) to (8) of section 7 of the Income Tax Act and Part X of the Eighth Schedule to the Act, as well as the general anti -avoidance measures in section 103. These measures impact negatively on the use of trusts for estate-planning purposes. The research objective was to evaluate the use of testamentary and inter vivos trusts for estate-planning purposes and to develop a holistic estate-planning model incorporating these planning instruments. Both the testamentary trust and the inter vivos trust were evaluated against broad principles of effective estate planning and the taxes and duties applicable to them. The research also reviewed the writings of financial planners on various techniques and models used for estate planning, as wells as case studies documented in the literature. The research developed and evaluated holistic estate-planning models incorporating testamentary trusts and inter vivos trusts, respectively. By neutralizing the effects of various taxes and duties, it was demonstrated that it is possible to develop an estate plan that satisfies most of the requirements of effective estate planning.

- Description: The global trends of democratisation and privatisation that swept much of the developing world in the 1980s and 1990s led to significant changes in the conceptualisation, organisation and performance of the media. In Africa democratisation attained a new meaning with associated processes of liberalisation of broadcasting to end the monopoly of broadcasting by the state. The private media of the liberalised market is increasingly putting the public media system, both broadcast and print, under serious competition, and forcing them to adjust to changing circumstances. The New Vision newspaper in Uganda is one such public service media organisations that are owned by the state and yet have to compete in the new more democratic and liberalised environment. This study set out to explore the extent to which state-ownership impacts on The New Vision’s social role. Using both qualitative and quantitative methods of date collection, I have established the that although The New Vision is a public service medium for which government remains the major source of news, it does not in most cases give the state more or preferentially prominent coverage at the expense of other interest groups in society. On contrary, basing of the amount of coverage of civil society I established that The New Vision enabled the various groups public sphere to interact. The newspaper to an extent also plays the democratic role of monitoring government although there was little evidence of monitoring of corporate abuse. The nature of The New Vision Statute, and the global trends that have changed the conduct of official and private business, have rendered the theories on the 1980s’ development media theories increasingly inapplicable, forcing The New Vision to develop its own version of development journalism that is socially relevant. The study recommends that whereas much of The New Vision Statute is progressive, sections of it should be removed to protect the newspaper from being manipulated by government functionaries, if the it is to continue enabling the public sphere. The newspaper should also increase its monitoring of corporate abuse, and make internal reforms to improve the coverage of development related issues.

- Description: Laccases are multi-copper oxidases endowed with huge applicability and versatility. They are found in nature, fungi, insects, archaea and bacteria; however, there is a dearth of information regarding bacterial laccases. Thus, the search for novel bacterial laccases becomes crucial. Therefore, the broad aim of the study was the assessment of some bacteria on marine water isolated from Eastern beach for the production of high activity laccases. In this study, marine water samples obtained from the Eastern beach in East London were investigated for bacterial laccase-producing isolates. The samples were analysed using different microbiological media and varied substrates via qualitative methods. The isolates were tested for laccase activity using ABTS (2, 2’- azinobis 3-ethyl-benzothiazoline-6-sulphonate), as a substrate. The present study also dealt with the optimization of culture conditions for laccase production and characterization of laccase. A total of forty-eight (48) bacterial isolates were obtained, which were identified based on their morphological and cultural characteristics. Many of the isolates (42) were categorized as Gram positive and a few (6) as Gram negative upon subjecting to microscopic examination. Result showed that on average, laccase activity ranged from 5.33 – 6.5 U/L as demonstrated by three bacterial isolates (Bacillus sp. NFN1, Bacillus sp. NLN and Escherichia coli LO). Laccase production was highly enhanced by the supplementation with vanillic acid by Bacillus sp. strain NLN with yield of 15.83 ± 0.7 U/L, Bacillus sp. strain NFN1, 12.72 ± 0.21 U/L. However, Escherichia coli LO demonstrated enhanced laccase production with guaiacol (12.84 ± 1.12 U/L) followed by ferrulic acid (12.8 ± 0.36 U/L). While optimization results revealed that the laccase yield was enhanced under the following conditions: 72 h of incubation, pH 5, 0.5mg/L lactose as a carbon source, 1. 5 mg/L yeast extract as a nitrogen source as well as in the presence of corn stover and mandarin peels as lignocellulosic substrates depending on the bacteria.The time course and stability of laccase against temperature, pH, metal ions and organic solvents were investigated using previously described methods. In the findings obtained for the time course, the laccase activity ranged from 22.2- 23.98 U/L. In general, the optimum parameters for the optimum laccase activities depended on the bacterial isolates and the time of incubation and included 80 °C and 70 °C, pH 3 and 9 while, the thermal stability was over 100%. Overall, NaCl, ZnSO4, NiCl and 20% acetone demonstrated positive effect on the residual activity of the laccases of all the bacterial isolates (Bacillus sp. NFN1, Bacillus v sp. NLN and Escherichia coli LO). In conclusion the findings of the study, suggest that marine water of the Eastern beach is a rich source for laccase producing bacteria with potential of high activity.
