- Description: Due to the growth increase in the wool industry in South Africa and the industry's lack of public activity that the existing South Africa (S.A) wool exchange exudes, the opportunity for a new type of wool exchange presents itself. the advantages in technology have evolved in many an industry and the same can be for the wool industry. the existing S.A. wool exchange fails to comfortably meet the needs of the industry with regards to technology. the creation of international wool exchange will provide a platform to boost the industry and incorporate the use of current technology to improve on the process involved within the program. BKB. Ltd have expressed a similar interest in the development of an international wool exchange but have requested the use of an abounded heritage building in an attempt at a sustainable future through re-use.

- Description: The concepts underlying this treatise develop from an observation of contemporary society’s inherent reliance on technology, its growing popularity as an information exchange mechanism and Africa’s lack of connection to it’s foundation, the internet. Human interaction with digital technology, supported by the internet, has created a new social culture which manifests meaning through visual and virtual cues. These make reference to place and are experienced as real and individual, relating to theories such as Heidegger’s imagined place (Heidegger 1971). In order to enhance Southern Africa’s connection with the global network of the internet, the design of an Internet Server Facility will bridge previously under-utilized international lines into the country at Port Elizabeth engaging with the existing infrastructural system. At this point of connection the infrastructural zone impedes the extension of a public environment. The design seeks to challenge the conception of the highway infrastructure in Port Elizabeth as objects that dehumanise space. It intends to emphasise structure and building as a set of processes or systems able to work together to enable not only the functional aspects of data infrastructure, but also respond to the urban fabric providing a multitude of spatial environments that engage with everyday human activity. Investigations of the previous impact of infrastructure which has been layered onto the edge of Port Elizabeth’s historical core, reveal the stripping of it’s place-making qualities over time, resulting in an urban wasteland. In considering the placement of an infrastructural system, an existing vacant space that forms part of the current infrastructure is more appropriate than using up other urban spaces. In its response, the system would need to respond to its urban environment in a way that infrastructure has previously failed to do in this area, due to its position adjacent to the CBD. For this reason the design is concerned with the urban rejuvenation of the scarred landscape and a design strategy for the development of a contemporary digital infrastructural system, capable of not only being a non-evasive to the urban environment but also a catalyst in the creation of physical and digital place-making in the public realm.

- Description: A lack of understanding of the multi-dimensional field of built environment heritage places the non-monumental fabric of historic city centres under great threat. This fabric plays a vital role in contributing to the collective significance and character of a place, despite its comparatively less remarkable nature. These buildings are often most susceptible to change, especially with regard to use. Responsible conservation and innovative design can allow buildings to undergo inevitable change, without compromising their heritage significance, despite the increasing demands of contemporary urban building typologies. Office typologies of the 21st century are particularly demanding with regard to efficiency, flexibility, sustainability and the need for a creative environment that promotes collaboration among knowledge workers. The document sets out a process by which to sensitively manage the juxtaposed relationship between historic buildings and a contemporary use, to generate an innovative design, resilient in its ability to retain the historic meaning of existing buildings.

- Description: This dissertation is based on the design of an Urban Agriculture Centre situated within the urban fabric of Port Elizabeth, South Africa. The treatise evolves out of issues pertaining to actual problems. Deforestation, desertification, floods, drought, population growth and pollution, only to name a few, are issues that play a crucial role in the survival of humanity and other ecosystems. After extensive research, it was identified that traditional farms are unsustainable, inefficient and causes great damage to the environment. Current farming methods will not be able to produce enough food for the growing population. Traditional farming relies on the climate and particular seasons to produce crops. At the rate that the population is growing, traditional farmers will not be able to keep up. Traditional farms use hectares and hectares of land - this is the one major disadvantage, as there is only a certain amount of arable land in the country. The treatise diagnosed this problem, and proposes that farming should move into the urban areas, where the majority of the population subsists. New generation farming techniques allows for agriculture to take place within the urban fabric. The agriculture technique that will be used in this treatise is hydroponics. The treatise addresses urban issues such as sprawl and wasted space within urban areas. For this reason, the treatise adopts a derelict industrial heritage building, within the Central Business District of Port Elizabeth, as the building that will be utilized by the proposed urban farm. The treatise has chosen the Old Premier Mill Building in Port Elizabeth as a suitable candidate for the proposed project. The building is over one hundred years old, and possesses unique heritage value. Using an existing building is a sustainable option, but for obvious reasons the treatise will be challenged to preserve the heritage value of the old Premier Mill building. The concept of an urban farm/vertical farm is perceived as a highly technical building, due to its nature, which demands a ‘high-tech’ aesthetic. The treatise challenges this contrast: designing a highly technical building while trying to preserve a structure of high heritage value. Part one of this dissertation sets the groundwork for the treatise and discusses the different aspects the of the project that will influence the design. Part two sets the foundation for all the aspects that will inform the treatise concerning the proposed project. The knowledge gathered in these two sections will be applied in part three of this dissertation.

- Description: South Africa is 20 years into democracy and it prides itself in the 1994 democratic elections. This document briefly looks into the era of the democratic governance and its impact on the less developing settlements in the Amathole and Amahlathi districts. The meanings and concepts of democratic governance are explored. Consequently, the findings convey that not everyone in South Africa and Eastern Cape are able to practice their right of accessing information or voicing their opinion concerning government in a formal platform. This contradicts the core values to democracy which imply a people centered approach where people lead the country (themselves) through the governing authorities. The frequent protests against service delivery are a clear indication that there is a break down in the communication between government and South African citizens. Material from the Council for Scientific and Industrial Research (CSIR) revealed that overpopulation, unemployment, poor education and lack of service delivery are the primary issues that hinder the progress of the region with reference to service delivery. Thus the primary objective of this research is to find ways to rehabilitate communication breakdown by creating a medium of clear dialogue between the government and its people. The architectural aim of this research is to design a district municipality that will be a connector of other municipalities, towns, settlements and precincts. The building aims to be a catalyst for development in the district that celebrates the heritage of the region. The project aims to communicate its fundamental concepts in the expression of the design, for example the permeability of the building will promote transparency, accessibility and integration with the community. In this way, democracy and its core principal of governing with the people will be done with less spatial hindrances.

- Description: Local government processes require meaningful and effective participation from both citizens and their governments in order to remain truly democratic. This project investigates the use of mobile phones as a tool for supporting this participation. MobiSAM, a system which aims to enhance the Social Accountability Monitoring (SAM) methodology at local government level, has been designed and implemented. The research presented in this thesis examines tools and techniques for the development of cross-platform client applications, allowing access to the MobiSAM service, across heterogeneous mobile platforms, handsets and interaction styles. Particular attention is paid to providing an easily navigated user interface (UI), as well as offering clear and concise visualisation capabilities. Depending on the host device, interactivity is also included within these visualisations, potentially helping provide further insight into the visualised data. Guided by the results obtained from a comprehensive baseline study of the Grahamstown area, steps are taken in an attempt to lower the barrier of entry to using the MobiSAM service, potentially maximising its market reach. These include extending client application support to all identified mobile platforms (including feature phones); providing multi-language UIs (in English, isiXhosa and Afrikaans); as well as ensuring client application data usage is kept to a minimum. The particular strengths of a given device are also leveraged, such as its camera capabilities and built-in Global Positioning System (GPS) module, potentially allowing for more effective engagement with local municipalities. Additionally, a Short Message Service (SMS) gateway is developed, allowing all Global System for Mobile Communications (GSM) compatible handsets access to the MobiSAM service via traditional SMS. Following an iterative, user-centred design process, a thorough evaluation of the client application is also performed, in an attempt to gather feedback relating to the navigation and visualisation capabilities. The results of which are used to further refine its design. A comparative usability evaluation using two different versions of the cross-platform client application is also undertaken, highlighting the perceived memorability, learnabilitv and satisfaction of each. Results from the evaluation reveals which version of the client application is to be deployed during future pilot studies.

- Description: In recent years the interest in implementing solar energy on vehicles (electrical and hybrid) has grown significantly [1]. There are currently limitations in this sector, such as the low energy density (efficiency of conversion) of this source, but it is still a renewable resource and as such, there is a growing interest [1]. A “smart” energy strategy implemented on a solar/electrical vehicle, in order to increase its energy harvesting volume, could enhance the growth of this sector. A tracking algorithm for a solar vehicle’s MPPT (Maximum Power Point Tracker) can be designed to source solar energy very effectively and to increase the speed of finding (tracking) this optimal sourcing point (solar panel voltage and current). Even though there are many different MPPT algorithms, it was decided that most of them were designed for stationary MPPT applications and the dynamics of implementing a MPPT on a vehicle create some unique scenarios. These include: Shadow flicker. This is rhythmic, rapid moving shadows across a solar panel, such as shadows from a line of trees: Rapid changes in solar panel orientation due to the road surface/relief; Rapid changes in panel temperature due to the location of the vehicle. The aim of the research can be divided into three outcomes: 1 Creating a “Smart” energy strategy/control, 2 Implement the new control system on a solar vehicle’s MPPT, and 3 Harvesting maximum energy from solar panels using the new energy strategy. The term “smart” is used to indicate the ability of the MPPT algorithm to be updated and improved based on previous results. A MPPT and scaled solar vehicle is designed and manufactured in order to test the MPPT algorithm. The purpose of using a self-developed experimental setup is to have more control over the system variables as well as having the maximum freedom in setting up the system parameters.

The development and evaluation of a new manufacturing process for β-sitosterol-D glucoside

- Description: The existing production sequence of β-sitosterol-D-glucoside, a glucoside used in an “over-the-counter” (OTC) preparation under the brand name of Moducare® comprises of three process steps with an overall yield of less than 20%. The low yield is partly due to the instability of intermediates at reaction temperatures > 0oC, and partly due to the thermodynamic equilibrium between two stereoisomers. An economically alternative process was developed, evaluated and scaled-up in a 2l reactor. The project was initiated with a specific limitation in terms of the starting material that comprised a mixture of plant sterols, which necessitated a study of the isolation and purification of the desired product from a rather complex reaction mixture. The use of silver as halide acceptor for the Koenigs-Knorr synthesis did not give statistically significant different results from the same approach but using cadmium as halide acceptor instead. However, using the direct O-glucosylation approach not only gave statistically significant higher results, but also resulted in a much more convenient procedure. Under optimum conditions, a yield of approximately 83% (isolated) of 2,3,4,6- tetra-О-acetyl-β-sitosterol-D-glucoside could be achieved, which was substantially higher than that achieved with the traditional Koenigs-Knorr methodology and above reported yields in the literature (60-80%) for direct glycosylation. Separation of 2,3,4,6-tetra-О-acetyl-β-sitosterol-D-glucoside (BSSGT) from a reaction mixture that contains 2,3,4,6-tetra-О-acetyl-campesterol-D-glucoside (CSGT), 2,3,4,6-tetra-О-acetyl campestanol-glucoside (CSSGT), and 2,3,4,6-tetra-О-acetyl-sitostanol-Dglucoside (SSGT) was investigated using column chromatography. When using silica gel particles, very good separation efficiency and product recovery could be achieved using hexane/ethyl hexane as eluent. The isolated 2,3,4,6-tetra-О-acetyl-β-sitosterol-Dglucoside was easily hydrolysed to β-sitosterol-D-glucoside in high yields (79%) using methanolic KOH. The process for the production of β-sitosterol-D-glucoside was scaled-up from the laboratory bench scale (250 cm3) to a laboratory scale of 2 l using the direct Oglycosylation method. The overall yields of the scaled reaction for β-sitosterol-D-glucoside was slightly above the literature reported values (59%, 8/92) for the KnoenigsKnorr synthesis and compares well above (62%, 0/100) the current production process (less than 20% yields). When using catalogue prices, the material costs (without recycling) for the direct Oglucosylation route is approximately 57% less for the synthesis of 1kg of β-sitosterol-Dglucoside compared to the Koenigs-Knorr route. Given further savings for recycling, the direct O-glucosylation route provides an attractive alternative route for the synthesis ofthe target compound.

- Description: The existing production sequence of β-sitosterol-D-glucoside, a glucoside used in an “over-the-counter” (OTC) preparation under the brand name of Moducare® comprises of three process steps with an overall yield of less than 20%. The low yield is partly due to the instability of intermediates at reaction temperatures > 0oC, and partly due to the thermodynamic equilibrium between two stereoisomers. An economically alternative process was developed, evaluated and scaled-up in a 2l reactor. The project was initiated with a specific limitation in terms of the starting material that comprised a mixture of plant sterols, which necessitated a study of the isolation and purification of the desired product from a rather complex reaction mixture. The use of silver as halide acceptor for the Koenigs-Knorr synthesis did not give statistically significant different results from the same approach but using cadmium as halide acceptor instead. However, using the direct O-glucosylation approach not only gave statistically significant higher results, but also resulted in a much more convenient procedure. Under optimum conditions, a yield of approximately 83% (isolated) of 2,3,4,6- tetra-О-acetyl-β-sitosterol-D-glucoside could be achieved, which was substantially higher than that achieved with the traditional Koenigs-Knorr methodology and above reported yields in the literature (60-80%) for direct glycosylation. Separation of 2,3,4,6-tetra-О-acetyl-β-sitosterol-D-glucoside (BSSGT) from a reaction mixture that contains 2,3,4,6-tetra-О-acetyl-campesterol-D-glucoside (CSGT), 2,3,4,6-tetra-О-acetyl campestanol-glucoside (CSSGT), and 2,3,4,6-tetra-О-acetyl-sitostanol-Dglucoside (SSGT) was investigated using column chromatography. When using silica gel particles, very good separation efficiency and product recovery could be achieved using hexane/ethyl hexane as eluent. The isolated 2,3,4,6-tetra-О-acetyl-β-sitosterol-Dglucoside was easily hydrolysed to β-sitosterol-D-glucoside in high yields (79%) using methanolic KOH. The process for the production of β-sitosterol-D-glucoside was scaled-up from the laboratory bench scale (250 cm3) to a laboratory scale of 2 l using the direct Oglycosylation method. The overall yields of the scaled reaction for β-sitosterol-D-glucoside was slightly above the literature reported values (59%, 8/92) for the KnoenigsKnorr synthesis and compares well above (62%, 0/100) the current production process (less than 20% yields). When using catalogue prices, the material costs (without recycling) for the direct Oglucosylation route is approximately 57% less for the synthesis of 1kg of β-sitosterol-Dglucoside compared to the Koenigs-Knorr route. Given further savings for recycling, the direct O-glucosylation route provides an attractive alternative route for the synthesis ofthe target compound.

- Description: People living with HIV and AIDS (PLHIV) suffer from a number of stress-related psychological disorders. The aim of this study was to develop an integrative intervention, which combined Cognitive Behaviour Therapy (CBT), Body-Mind Therapy and Multicultural perspectives to assist health care workers in identifying and treating stressrelated psychological disorders among people living with HIV and AIDS. The study employed an intervention research design using both qualitative and quantitative methods. The quantitative data was collected from PLHIV attending HIV Counselling and Testing (HCT) and Anti-retroviral therapy clinics in the Buffalo City Municipality (BCM) of the Eastern Cape Province. The qualitative data was collected from the health care workers of the selected study sites. Purposive sampling was used to select the study sample. Instruments used included a biographical questionnaire, the Beck Depression Inventory-II (BDI-II), Medical Outcome Study- HIV (MOS-HIV) and focus group interviews to gather data for the development of an intervention model that would address reported stress-related psychological disorders. Findings showed that people living with HIV and AIDS endure stress in their lives on daily basis rather than episodes of severe or clinical depression. Many of the PLHIV are dealing with a number of psychosocial problems that compromise their quality of life and health status. In conclusion, the study illustratively interpreted and discussed the results in relation to the objectives of the study. The study recommends that PLHIV should be exposed to stress management programmes, and health care workers (HCWs) should be offered training in basic counselling skills, stress management and/or debriefing.

- Description: This dissertation develops a standard device model for networked audio devices and introduces a novel discovery and control environment that uses the developed device model. The proposed standard device model is derived from a study of current audio control protocols. Both the functional capabilities and design principles of audio control protocols are investigated with an emphasis on Open Sound Control, SNMP and IEC-62379, AES64, CopperLan and UPnP. An abstract model of networked audio devices is developed, and the model is implemented in each of the previously mentioned control protocols. This model is also used within a novel discovery and control environment designed around a distributed associative memory termed an object space. This environment challenges the accepted notions of the functionality provided by a control protocol. The study concludes by comparing the salient features of the different control protocols encountered in this study. Different approaches to control protocol design are considered, and several design heuristics for control protocols are proposed.

- Description: The Southern African Development Community (SADC) region, like most parts of the African continent, faces significant modern energy services access challenges. It is estimated that less than 45% of the SADC region’s populace have access to reliable modern energy forms and the situation is worse in rural areas where access is approximately 30%. Poor energy security is exacerbated by electricity power cuts and load shedding in almost all of the member states in the region. With the advent of battery storage, all forms of green energy have the potential to contribute to the shortfall in the supply of peaking power required to meet the daily (morning and evenings) and seasonal (winter) peaks when most power is required on the grid network. The region is endowed with vast green (renewables/low carbon or clean) energy resources. The purpose of this study is to expand the empirical body of research and knowledge on factors that contribute to widespread access success to green energy in the SADC region. Investments into green energy resources require an understanding of the unique characteristics of the energy sector in the region. In order to achieve this, a conceptual theoretical model was developed and tested empirically. Factors that influence green energy access success were identified through literature reviews and discussions with energy practitioners. All identified factors were then operationalised by carefully defining them in the context of the study. In order to test the proposed theoretical model and the hypothesised relationships, a structured questionnaire was developed and sent to energy practitioners from various sections of the energy sector in the region. STATISTICA 12 was employed to analyse relationships between variables and responses between identified groups. Pearson Product Moment Correlation (Pearson r) was employed to determine correlations between variables. Conclusions about hypotheses six (6) to fifteen (15) were made based on correlations between variables. T-tests were employed to make inferences about the views of various categories of respondents with regard to the twelve (12) identified variables. Multivariate analysis of variance (MANOVA) and Analysis of variance (ANOVA) examined associations between the dependent and independent variables with the identified categories of respondents and conclusions about hypotheses one (1) to five (5) and sixteen (16) were also made. The study finds that policy and the regulatory environment are still the main driving force behind energy access in the region. Power generation is managed by authorities’ power utility companies. Unbundling of power utilities supported by new energy business and operating models to accommodate mini and off grid power plants is found to be a key to green energy access in the region. The energy market is transforming in favour of independent power producers (IPPs) and consumers will significantly influence energy access decisions in the future. Green energy power storage to overcome intermittency will feature prominently in the success of green energy access in the region. Widespread access success to green energy will be attained when green energy access is reliable, affordable, efficient, and socially acceptable, meet the demand and reduces environmental pollution. The study recommends that strategic green energy planning must incorporate green energy infrastructure development, projects finance and human capacity development as priorities amongst SADC region’s member countries. Regional energy access enabling institutions must be strengthened; energy policies implemented with vigour and private sector participation enhanced in an integrated energy market.

- Description: This research attempts to create a recommended digital marketing strategy for Pan Macmillan, South Africa. As a result of the advance of technology and the increase of connectivity, digital marketing is becoming a highly important tool with regards to competitive advantage, differentiation and the overall marketing of a company and its product or service (Barwise and Farley, 2005, p. 68). Digital marketing is, in South Africa specifically, a relatively new concept (Sandmann, 2014, p. 1). If South African companies are able to efficiently utilise the gap in the market, they will ensure a significant competitive advantage (Sandmann, 2013, p. 1). In order to accomplish this successfully a digital marketing strategy must be created and adopted to ensure a full understanding of the requirements of effective digital marketing. This research focusses on understanding digital marketing requirements in relation to a South African book publisher and how those requirements can be met by the publisher through the development of a digital marketing strategy. The literature has been reviewed and previous research indicates that an established framework is needed to guide the development of a digital marketing strategy. The framework used in this research is the RACE framework (Chaffey and Bosomworth, 2013, p. 14) which is used in conjunction to the SOSTAC planning system (Chaffey and Bosomworth, 2014, p. 11) and the 7 steps to digital marketing strategy creation (Chaffey and Bosomworth, 2014, p. 2). The literature suggests that a combination of the established traditional marketing strategy of a company and current digital marketing practices and tools is the most practical with regards to the development of a successful digital marketing strategy, implementation and evaluation. In order to understand the current marketing strategy and practices of Pan Macmillan, interviews with the Marketing Manager of the company were conducted as well as an analysis of marketing documents relating to Pan Macmillan’s current marketing actions. Results of the interviews and documentation analysis showed that Pan Macmillan had many elements digital marketing but no decisive digital marketing strategy. Using the selected frameworks and information gathered on the company’s marketing practices, digital marketing goals were established and a digital marketing strategy was created. The goals of the research were reached as a recommended digital marketing strategy was developed for Pan Macmillan based on the assessment made, using RACE, SOSTAC and the 7 steps to digital marketing creation, of the company’s current practices, challenges and opportunities with regards to digital marketing.

- Description: The rapid increase in student enrolment in universities has brought about a number of concerns, including off campus student housing as Institutions of Higher Learning are unable to accommodate all students on campus. Due to the extremely small number of students that are currently being accommodated on campus, many students are forced to find accommodation off campus. Property owners nearby Institutions of Higher Learning have begun letting their homes to students for economic gain. Housing of students has become a new business venture for many surrounding houses and large buildings. This study examined some of the problems associated with non-accredited accommodation in Summerstrand in order to provide recommendations towards a policy for off campus student accommodation. The study investigated the experiences of both students and landlords in order to establish some of the requirements a property owner needs to meet in order to be legible to house students. Ultimately the study will make recommendations for an effective policy for off-campus student accommodation in the Nelson Mandela Bay. An effective policy for the development of student housing in the Nelson Mandela Bay needs to be formulated as students can be exploited by landlords and landlords can exploited by students. The study identified 4 particular areas of concern namely rent, security, facilities and maintenance; and provided recommendations for the policy for off-campus accommodation.

- Description: With Eskom’s fleet rapidly reaching end of life and maintenance outages becoming more frequent, it has become more critical to be able to determine transient effects of auxiliary losses and system responses due to instabilities. A low mono-nitrogen oxide (low-NOx) burner replacement project has recently been completed at Camden power station in Ermelo. It has thus deemed itself as a perfect candidate for a model which can be used to understand the new systems’ response during transient scenarios. The aim is to develop a boiler control model to be used for simulation of various process conditions and failure scenarios in order to predict the boiler plants’ behaviour and improve its availability. Research was done on common boiler control practices and modelling of boiler control. A theoretical boiler control model was developed based on the Camden power station’s control system specification. The computational model of the boiler control was implemented in Flownex® simulation environment, which was found to be particular useful for modelling industrial applications. A number of simulations with the computational model were performed and the results were compared against the historic plant data showing good correlation. In parallel, a thermo-fluid model of the boiler was developed using Flownex® by a Masters student at the University of Cape Town, which was then integrated with the control model. The combined Flownex model was used for simulation of the following important cases: a mill trip, a Forced Draught fan trip and load changes. The obtained results show good correlation with the real plant data, indicating that the developed computational model can be considered accurate for Camden’s particular type of boiler and its control. Hence, it is envisaged that the developed combined Flownex model can be applied for simulation of the boilers of the Camden power station.

- Description: Bioinformatics is now a critical skill in many research and commercial environments as biological data are increasing in both size and complexity. South African researchers recognized this need in the mid-1990s and responded by working with the government as well as international bodies to develop initiatives to build bioinformatics capacity in the country. Significant injections of support from these bodies provided a springboard for the establishment of computational biology units at multiple universities throughout the country, which took on teaching, basic research and support roles. Several challenges were encountered, for example with unreliability of funding, lack of skills, and lack of infrastructure. However, the bioinformatics community worked together to overcome these, and South Africa is now arguably the leading country in bioinformatics on the African continent. Here we discuss how the discipline developed in the country, highlighting the challenges, successes, and lessons learnt.

Different reducing agents (PPh3, Na2S2O5 and NaBH4) were employed and consequently, different results were acquired, such as rhenium(V)-mediated oxidative hydrolysis of the phthalocyanines (Pcs), the formation of a rhenium-phthalocyanine complex and phthalocyanine-capped nanoparticles. The rhenium nanoparticles that were formed were optimized from a synthesis point of view and, cancer localizing ability of the rhenium nanoparticles was investigated. The complexes were synthesized through direct metalation of pre-formed metal-free phthalocyanines using the “cold isotopes” of the rhenium metal. Rhenium nanoparticles (Re NPs) were synthesized in aqueous saline medium so as to imitate the environment on which Re is produced from its reactor. The nanoparticles (NPs) were capped with phthalocyanines which were covalently biofunctionalized with a folic acid moiety to enhance the targeting ability of the Re NPs. These NP systems were characterised with techniques such as ultraviolet-visible UV-Vis spectroscopy and transmission electron microscopy TEM. Cytotoxicity of the NPs was tested against four different cell lines and subsequently their cytotoxicity profiles were elucidated, and the profiles shown a dose-dependent responsealthough the results in some cell lines were unclear. Their fluorescence properties were also studied to provide photophysical information for investigation of their tumor localization using human cancer cells lines via confocal fluorescence microscopy studies. Particle size effect on localization of NPs was also investigated using confocal fluorescence and TEM. Two sizes were chosen (10 and 50 nm), and the smaller NPs (10 nm) were found to exhibit stronger fluorescence properties than the 50 nm NPs, and they were also found to have a better localization ability than the 50 nm NPs. Finally, their tumor and organ biodistribution studies will be carried out using micro-SPECT kits and model mice (using the “hot” isotopes in a radiopharmacy laboratory).

- Description: The Kenyan language in education policy contemplates development of trilingual literacy skills in pupils by the end of standard three. The purpose of this study was to determine to what extent standard three pupils were literate in their mother tongue (Ekegusii), Kiswahili, and English. The study was undertaken in the context of; a language in education policy that provides for the use of mother tongues and Kiswahili (as languages of instruction) in rural and urban schools respectively up to the end of standard three, followed by a transition to an English medium from standard four; a general negative public attitude towards mother tongue instruction; and substantial empirical evidence in support of mother tongue instruction in basic education. Cummins’ Linguistic Interdependence and Linguistic Threshold Hypotheses guided the study. Adopting a mixed methods approach, the study used direct classroom observations, face-to-face interviews, document analyses, and reading tests to obtain data. Thematic, content, and statistical approaches were used in data analysis. It was found that various stakeholders understand key aspects of the language in education policy differently. Secondly, efforts in mother tongue instruction in schools are not motivated by theoretical and empirical foundations; development efforts are hence ineffective and inadequate leaving majority of learners with below average literacy skills in their mother tongue by the end of standard three. Thirdly, teachers do not implement the language in education policy as spelt out in the relevant documents; the three languages have therefore been allocated various classroom functions. Fourthly, the factors that motivate the disregard of the language policy include the language of examinations and textbooks, and transition to standard four in which English is the language of instruction. Lastly, reading scores indicate that majority of pupils transiting to standard four do not possess adequate reading skills to enable them read to learn in a mother tongue, Kiswahili, and English. This is observed across rural, peri-urban, and urban schools. The study recommends that: The ministry of education conducts workshops to re-educate the relevant stakeholders on the meaning and significance of the language in education policy and the significance of mother tongue instruction in second language, literacy, and skill development. This should be followed by a re-classification of primary schools on the basis of linguistic homogeneity, or otherwise, to ensure the intention of the policy is achieved. This could include empowering individual schools to determine language of instruction in lower primary based on language predominance. Secondly, the ministry should provide relevant resources for mother tongues and Kiswahili to develop them as effective languages of instruction as recommended by various past education commission reports. Additionally, a bilingual course in teacher training colleges to equip primary school teachers for bilingualism and biliteracy development should be introduced; one implication of this is teachers giving notes and tests in the languages spelt out in the policy. Thirdly, the ministry should intensify inspection of schools to assess implementation of the policy. Fourthly, future studies should assess mother tongue literacies as well, since they determine the extent and success of second language acquisition and learning; and measures should be put to ensure English is adequately resourced and taught well. Finally, mother tongue instruction should be extended up to, at least, standard five.

- Description: The aim of this study was to establish whether the South African Broadcasting Corporation (SABC) performed according to its mandate in ensuring a fair broadcast coverage of all political parties that participated in the 2014 national general election. The study was undertaken as a result of the complaints by political parties who accused the SABC of bias during the election. The study focused on two SABC radio stations, namely SAFM and UKHOZI FM. In executing the research, particular attention was paid to the coverage of political party manifestos, town hall election debates and radio interviews. The study was written utilising the theoretical paradigm of Social Responsibility Theory, as this is largely deemed the most ethical guide in testing South African journalism. The research was conducted in accordance with the Independent Complaints Authority of South Africa (ICASA) regulations that govern broadcast media during elections. The second part of the analysis deconstructed the SABC’s media coverage of the 2014 election through Media Monitoring Africa – a non-profit organisation that monitors and reports on media coverage of elections, whilst simultaneously taking ICASA stipulated guidelines into account. The MMA and ICASA equipped the study with reports which were compiled after an intense monitoring of SABC’s coverage of the 2014 election. Through the analysis of political parties’ accessibility to the election broadcast programmes on SABC platforms, the study concluded that although there were errors, the SABC treated all parties fairly during the 2014 general elections. The study also found that poor corporate governance at the SABC did not impact directly on the public broadcaster’s ability to deliver fair election broadcasting. By conforming to the social responsibility role that calls for high professional conduct, fairness and objectivity as expected in the public broadcaster, this study found that the SABC was committed to a fair coverage of the 2014 election.
