- Description: The resurgence of Islam across the globe combined with the resilience that Islamic financial assets have shown against the onslaught of the current financial crisis, make Islamic finance an attractive alternative financial system. Over the past decade, the Islamic finance sector have shown double digit growth rates beyond the traditional areas of the Gulf Cooperation Council (GCC) regions of Asia as well as other parts of the Middle-East and North Africa (MENA) regions. Research suggests that the future of Islamic finance in Africa depends on business opportunities in South Africa, Kenya, Nigeria and Senegal. The South African government, in conjunction with the national finance authorities, have made their intention clear to position the country as the Islamic finance hub for the rest of the African continent. Despite various marketing campaigns over the past decade to convince the public that Islamic banking and finance is for everyone, non-Muslims generally view Islamic banking as being for Muslims alone. Scepticism towards Islamic finance has resulted in a mere 15 per cent of the estimated 1.5 million South African Muslims currently making use of the sector’s banking and retail instruments. This lack of interest is impacting negatively on the country’s aspirations to establish itself as the gateway of Islamic finance to the rest of Africa. Generally, people’s attitudes toward utilising Islamic finance are regarded as a key obstacle to the development of the Islamic banking and finance system in Muslim minority countries. A Kuwait Finance House research report (2012) highlighted a lack of awareness and knowledge of Islamic finance products and services as key factors stifling the growth of the Islamic finance sector in South Africa. In this context, it was deemed necessary to analyse how knowledge, awareness, expectations, beliefs, perceptions and ancillary external factors impact on potential users’ attitude and decision to adopt or reject Islamic finance.By means of adapting Fishbein’s (2000; 2008) Integrative Model of Behavioural Prediction, a universally-acceptable behavioural-change model, this research explains in a holistic manner how cognitive, affective and environmental measures impact on a Port Elizabethan Muslim’s attitude and eventual decision to accept (or reject) Islamic finance. This study has found that knowledge was the most important variable influencing attitude and intention to use (or reject) Islamic finance. Consequently, this thesis proposed that Islamic institutions should focus their efforts on promoting knowledge and awareness of their products among the South African Muslim and non- Muslim population. As the global Shari’ah finance industry continues its positive growth trajectory, it is imperative that Islamic finance stakeholders in South Africa ensure that they exploit the benefits derived from online learning platforms and assist, by means of cross-border collaborations, more students to have greater access to Islamic finance courses. Furthermore, universities and training institutions are encouraged to offer courses and qualifications in Islamic finance to close the talent gap that currently exist in this particular field of study.

- Description: The present Thesis pioneer the application of single-source molecular precursor method for the synthesis of ruthenium sulfide nanoparticles using a series of novel self-prepared single-source molecular precursors. The preparation of precursors involved the design and synthesis of compounds containing all the desired elements required within the coordination compound. Good precursors are tailored to give reproducible, clean decomposition at moderate temperatures, leading to high quality, defect free, mono-dispersed nanoparticles. Nine (9) homonuclear tris-dithiocarbamato ruthenium(III) complexes, [Ru(S2CNR2)3] were prepared from a stoichiometric reaction of RuCl3·H2O with self-prepared dithiocarbamate ligands at room temperature in a molar ratio of Ru3+: Ligand of 1:3. Dithiocarbamate ligands were derived from a stoichiometric reaction of carbon disulfide with (aniline, N-allylmethylamine, p-toluidine, p-anisidine, N-ethyl-m-toluidine, piperidine, morpholine, di-isopropylamine, and diallylamine) in the presence of concentrated ammonia or potassium hydroxide in ice cold bath. The dithiocarbamate ligands and complexes were characterized by elemental analyses, UV-Vis, Fourier transform infrared spectroscopy (FTIR), 1H- and 13C-NMR spectroscopy. Thermogravimetric analyses (TGA) was used to study the decomposition profiles of the precursor complexes. The results obtained from the TGA of precursors showed that the complexes decompose to ruthenium sulfide nanoparticles. The FTIR spectra of the ligands revealed prominent strong absorption bands ascribed to v(N-H) stretching vibrations and also confirm the bidentate coordination of the dithiocarbamate ligands. Ruthenium(III) complexes show absorption spectra in the visible region that exhibit bands attributed to n → π* electronic transitions located on the sulfur atoms located in the S–C–S and N–C–S chromophores of the bidentate dithiocarbamate ligands respectively. The absorption spectra also confirmed the geometry of ruthenium(III) complexes to be octahedral. The proposed structures of dithiocarbamate ligands and ruthenium(III) complexes were confirmed by the 1H- and 13C-NMR. The complexes were used as single-source molecular precursors for the synthesis of ruthenium sulfide nanoparticles. The structural and optical properties were studied using transmission electron microscope (TEM), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), UV-Vis absorption and photoluminescence (PL) spectra. FTIR revealed that Ru2S3 nanoparticles are capped through the interaction of the –NH2 group of hexadecylamine HDA adsorbed on the surfaces of nanoparticles and it also showed that oleic acid (OA) is acting as both coordinating stabilizing surfactant and capping agent. The XRD confirmed the successful formation of Ru2S3 nanoparticles induced by the thermal decomposition of series of [Ru(S2CNR2)3] complexes. The diffraction peaks: 2θ = 29.43, 40.54, 49.33, 51.86, 61.92, and 75.94 were assign the Miler indices (hkl) to be (111), (211), (220), (300), (222) and (330) reflections, respectively, and were found to be in agreement with a cubic crystal structure reported in database file of (JCPDS 19-1107). The particle sizes estimated from Scherer's equation were found in a range between 2.5 and 4.9 nm. EDS spectra reveal that the prepared nanoparticles are mainly composed of Ru and S, confirming the presence of Ru2S3 nanoparticles in cubic phase. The inner morphology of nanoparticles was obtained by transmission electron microscopy (TEM) and most nanoparticles had narrow particle size distribution characterized by an average diameter of 8.45 nm with a standard deviation of 1.6 nm. The optical band gap (Eg) determined from Tauc plot was found in the range (3.44 to 4.18 eV) values.

- Description: This study was an exploration of self-determined development practices as a panacea for poverty reduction in the San communities. The main aim of this study was to propose possible strategies for eliminating the marginalisation of San in order to reduce poverty. This study was guided by an Indigenous research paradigm. This study used an Indigenous research methodology because it ensures that research on Indigenous issues is carried out in a more respectful, ethical, correct, sympathetic, useful and beneficial fashion seen from the point of Indigenous people. Nine out of thirty-six villages in Tsumkwe East participated in this study. Data collection was done through key informant interviews and conversational methods namely talking circles and storying. The findings of this study reveal that the marginalisation of the Ju/’hoansi San of Nyae Nyae and other San communities is closely related to their loss of ancestral land during the colonial and post-colonial era. Although the Ju/’hoansi San have fought to maintain their ancestral lands, hunting which is their main livelihood has been restricted by government regulation. The restriction on their hunting and gathering culture has been the major contribution to their marginalisation as they can no longer fend for themselves as their forefathers used to do. Despite a multitude of factors militating against the self-determination of San communities, the Ju/’hoansi San have managed to express their voice through a remnant of their hunting and gathering culture. This study also reveals that there are two important actors in Nyae Nyae namely the government of the Republic of Namibia and the Nyae Nyae Conservancy. Nyae Nyae Conservancy is a community based natural resource management organisation which has taken a participatory developmental approach to the development of Tsumkwe East. The government has taken more of a welfare approach. Although the mainstream has labelled San people lazy, uneducated, backward and uncivilised, the success of the Nyae Nyae Conservancy which is managed by the Ju/’hoansi San is a testimony to the contrary. This study reveals that the government has failed to deliver on its policy of meeting all the welfare needs of the Ju/’hoansi San but the conservancy has risen to be a relevant organisation meeting the needs of the community whilst respecting their culture and identity as a hunting and gathering community. This study concludes that self-determined development practices maybe a panacea for the development of San communities. This can be made possible by supporting the San’s hunting and gathering livelihoods, respecting their culture, securing their land and resource rights, through long-term and consistent capacity building and supporting a culturally relevant education system.

- Description: This research was conducted with the intention of accomplishing effective property management (PM) in order for public sector properties in South Africa (SA) SA to fulfil more remarkably, public sector property stakeholders’ requirements. In particular, this study was concluded within a South African municipal environment with the specific purpose of alleviating South African municipalities from problems associated with overall poor operational performance, dissatisfied public sector property stakeholders, and inadequacies in competitiveness and global alignment. The primary objective of this study was to develop a performance model deemed necessary for the effective management of public sector properties in SA. This was achieved by developing a performance model for effective management of public sector properties, a model to systematically monitor, measure and control current expectations and changes within a public sector property management function. Herewith, performance model for effective management of public sector properties in South Africa. At the time of conducting this study, there was no conceptual model developed for performance management of public sector properties. In order to develop the performance model, the conceptual model identified key elements that included: 1) obsolescence and strategic factors; 2) global alignment; 3) finance and cost control; 4) PESTEL impact; 5) transformation and sustainability; 6) leadership and governance; and 7) monitoring, measurement and control as influences that directly impact a perceived successful management of public sector properties in SA. The study also took the form of a quantitative research project that included a formal survey of the identified population sample. The main statistical procedure employed was Structural Equation Modelling (SEM). Originally, the study offered 24 hypotheses; however, only 11 hypotheses could be confirmed by SEM measurement. Therefore, through SEM, the significance of the relationships between variables could be tested. Appropriate quantitative data were collected from public and private South African Built Environment professionals, students and other academics. The research made use of snowball sampling through questionnaires, with a sample size of 171. It is anticipated that findings of this study will be acknowledged by public sector PM in an effort to resolve PM problems through the incorporation of pertinent recommendations. Likewise, since the performance model for effective management of public sector properties was not extant prior to this study, this research is cutting-edge and therefore pioneering to PM, especially within the public sector.

- Description: This study is divided in to two main parts. The first part deals with the optimization of process parameters of needle-punched non-woven fabrics for achieving maximum sound absorption by employing a Box-Behnken factorial design. The influence of fibre type, depth of needle penetration and stroke frequency on sound absorption properties were studied. These parameters were varied at three levels during experimental trials. From multiple regression analysis, it was observed that the depth of needle penetration alone was the most dominant factor among the selected parameters, which was followed by the interaction between depth of needle penetration and stroke frequency. Fibre type was the least dominant parameter affecting sound absorption. A maximum sound absorption coefficient of 47% (0.47) was obtained from the selected parameters. The results showed that for a process such as needle-punching, which is influenced by multiple variables, it is important to also study the interactive effects of process parameters for achieving optimum sound absorption. The second part of the study deals with the effect of type of natural fibre (fineness), and the blending ratio (with PET fibres) on the air permeability of the needle-punched non-woven fabrics and then it proceeds to study the effect of the air-gap, type of natural fibre (fineness) and blending ratio (with PET fibres) on sound absorption of needle-punched non-woven fabrics. These parameters are tested individually and their two way interaction (synergy) effect using ANOVA. The air-gap was varied from 0mm to 25mm with 5mm increments, three natural fibre types were used and all were blended with polyester fibres at three blending ratios for each natural fibre type. The Univariate Tests of Significance shows that all three parameters have a significant effect on sound absorption together with two two-way interactions, with the exception of the Blend Ratio × Air Gap two-way interaction which was not significant. It was found that the sound absorption improves with the increase in the air-gap size up to 15mm after which sound absorption decreased slightly with the further increase in the air-gap up to 25mm.

- Description: Adaptive water resource management requires sound scientific based decisions, emanating from robust scientific data. The Department of Environmental Affairs are mandated for collaborative management of the South African coast, including estuaries, through the Integrated Coastal Management Act (Act no 24 of 2008) (ICMA). The Department Water and Sanitation is mandated through the National Water Act (Act no 36 of 1998) (NWA) to design, test and implement monitoring programmes to provide water resource data. Extensive freshwater monitoring programmes exist in South Africa but there is no standard long-term monitoring programme for estuaries. This study designed and tested a National Estuarine Monitoring Programme (NESMP) that is anchored in the NWA and the ICMA. The design was based on a review of international estuary monitoring programmes, consultation with relevant role players and five decades experience in the design, testing and implementation of water resource monitoring programmes by DWS. The main objective of this thesis is 1) to design a national estuarine monitoring programme 2) test the design of the programme for practical implementation by reflecting on collected data from case studies, and 3) design a Decision Support System to translate complex monitoring data into management information. The main objective of the NESMP is 1) to collect long-term data to determine trends in the condition of estuaries in South Africa and 2) to provide management orientated information for effective estuary management. The National Estuary Monitoring programme consists of three tiers. Tier 1 focuses on basic data including system variables and nutrient data. Tier 2 collects data required for the determination of the Ecological Water Requirements (EWR) of estuaries in accordance with a standardised method used by DWS. A tailor made monitoring programme addressing specific issues including pollution incidents and localised development pressure, making use of a combination of Tier 1 and Tier 2 components, forms Tier 3 of the NESMP. This study tested the Tier 1 components of the programme on 28 estuaries across the South African coast since 2012. However, due to space constraints, the data reflected on in this thesis, is only for case studies on the Berg and Breede estuaries between 2012 and 2016. The results indicate that the establishment and operation of the NESMP on South African estuaries making use of monthly surveys, and the deployment of permanent water quality loggers, in line with the proposed protocol, are possible. This does however require collaboration with other role players in order to share responsibility and associated resources. A tiered management structure ensures national, regional and local level implementation takes place seamlessly. A decision support system (DSS) was also designed as part of this thesis to assist with data interpretation and the creation of management orientated information. This DSS includes a measurement of the percentage exceedance of the Threshold of Potential Concern (TPC), which acts as an early warning system for water resource deterioration. This study showed that effective collaboration will ensure the sustainability of the NESMP. Implementation of the more complex and resource intensive Tier 2 and Tier 3 sampling will however need to be investigated to establish the overall success of the NESMP.

The Department of Environmental Affairs are mandated for collaborative management of the South African coast, including estuaries, through the Integrated Coastal Management Act (Act no 24 of 2008) (ICMA). The Department Water and Sanitation is mandated through the National Water Act (Act no 36 of 1998) (NWA) to design, test and implement monitoring programmes to provide water resource data. Extensive freshwater monitoring programmes exist in South Africa but there is no standard long-term monitoring programme for estuaries. This study designed and tested a National Estuarine Monitoring Programme (NESMP) that is anchored in the NWA and the ICMA. The design was based on a review of international estuary monitoring programmes, consultation with relevant role players and five decades experience in the design, testing and implementation of water resource monitoring programmes by DWS. The main objective of this thesis is 1) to design a national estuarine monitoring programme 2) test the design of the programme for practical implementation by reflecting on collected data from case studies, and 3) design a Decision Support System to translate complex monitoring data into management information. The main objective of the NESMP is 1) to collect long-term data to determine trends in the condition of estuaries in South Africa and 2) to provide management orientated information for effective estuary management. The National Estuary Monitoring programme consists of three tiers. Tier 1 focuses on basic data including system variables and nutrient data. Tier 2 collects data required for the determination of the Ecological Water Requirements (EWR) of estuaries in accordance with a standardised method used by DWS. A tailor made monitoring programme addressing specific issues including pollution incidents and localised development pressure, making use of a combination of Tier 1 and Tier 2 components, forms Tier 3 of the NESMP. This study tested the Tier 1 components of the programme on 28 estuaries across the South African coast since 2012. However, due to space constraints, the data reflected on in this thesis, is only for case studies on the Berg and Breede estuaries between 2012 and 2016. The results indicate that the establishment and operation of the NESMP on South African estuaries making use of monthly surveys, and the deployment of permanent water quality loggers, in line with the proposed protocol, are possible. This does however require collaboration with other role players in order to share responsibility and associated resources. A tiered management structure ensures national, regional and local level implementation takes place seamlessly. A decision support system (DSS) was also designed as part of this thesis to assist with data interpretation and the creation of management orientated information. This DSS includes a measurement of the percentage exceedance of the Threshold of Potential Concern (TPC), which acts as an early warning system for water resource deterioration. This study showed that effective collaboration will ensure the sustainability of the NESMP. Implementation of the more complex and resource intensive Tier 2 and Tier 3 sampling will however need to be investigated to establish the overall success of the NESMP.

- Description: Breast cancer is the most frequently diagnosed cancer in women worldwide.A treatment regime, both effective and safe and can only be achieved once more effective chemotherapeutic agents are discovered or identified. These “drugs” must selectively induce cell death such as apoptosis or necroptosis in the cancer cells. Apoptotic cell death allows a cell to “commit suicide” in genetically- controlled or programmed mechanism(s). The microenvironment of the tumour is important since a nurturing malignant environment is required for tumour maintenance, progression and ultimately the development of metastasis. Due to the correlation of the tumour microenvironment to aggressive tumour progression, emphasis should be placed on the constituents of the tumour’s microenvironment. In recent years, the understanding of intracellular pathways in cancer cells has increased rapidly, contributing to the development of drugs with more specific targets such as growth factors, signalling molecules, cell adhesion proteins, proteases, cell-cycle proteins, modulators of apoptosis and molecules that promote angiogenesis and metastasis. The main aim of this study was thus to identify a few potential or active compounds from a library of synthetically-derived compounds as possible alternative breast cancer treatment candidates.

- Description: An exchange-rate regime is an essential element of a country’s regional and international trade, since it is the monetary link between its domestic and international economy. Appropriate exchange-rate regimes that would facilitate capital flows, trade, Foreign Direct Investment (FDI) and economic growth need to be identified and researched within the Southern Africa Development Community (SADC). This study investigated five underlying themes on exchange-rate regimes, behaviour and monetary policy-related issues in the SADC region: the different exchange-rate regimes’ performance and features – before, during and after the 2007/2008 financial crisis; the implication of the adopted exchange-rate regime on monetary-policy independence through examining the impact of the U.S. interest rate on domestic interest rates; the transmission of the South African exchange-rate volatility to other SADC currencies during and after the 2007/2008 financial crisis; the relationship between the exchange-market pressure and monetary policy, and the relationship between exchange rates and stock prices. The following models were used to address the identified themes: the Exchange-Flexibility Index; the Regression-Based Model; the General Methods of Moments (GMM) Model; the GARCH (p, q) Model; the Exponential GARCH Model; the VAR framework, and the Granger-Causality Tests in the VAR System, with their Impulse Response Functions (IRF) and Variance Decomposition. These models were applied to cover different aspects of the study before, during and after the 2007/ 2008 financial-crisis periods. They enabled critical evaluation of the exchange-rate policies, behaviours and performances. The results of the thesis indicate that, in general, both fixed and flexible exchange rates became more flexible after the crisis period and the influence of the United States (U.S.) Dollar, Chinese RMB and EURO was affirmed. There was no evidence of an increase in the co-ordination of SADC currency arrangements in the post-crisis period. Countries with a fixed exchange-rate regime responded more to international interest rates. The study further confirmed the presence of the Rand volatility-contagion effect during the crisis period, as well as its spill-over effect during tranquil periods, to most currency markets in the region. The evaluation of the relationship between the Exchange-Market Pressure (EMP) and monetary policy relationship revealed their close interdependence. This confirms traditional theories that a tighter monetary policy reduces the EMP. The portfolio theory was further affirmed in that stock prices Granger-cause the exchange rates. The recommendations emanating from this study include modernisation of the financial systems of SADC states to cope with foreign capital flows and external shocks, especially since global and regional economies are intensifying, as well as deepening of financial regulations and supervision of financial systems. Furthermore, there is a need for governments and central banks to synchronise their economic policies to minimise the negative effect of global financial crises. The fixed exchange rate regimes and intermediate regimes proved more suitable to countries with less exposure to global capital markets. However, they should prepare their financial institutions to cope with the transition from peg arrangements to more flexible exchange rate regimes. Countries are more appealing if they have more advanced financial markets, links to global capital markets and flexible exchange rate regimes. SADC countries will eventually engage in full global financial integration because of the intensification of global financial markets. This will require the countries to adopt exchange-rate stability and financial integration, but sacrifice monetary autonomy; alternatively, they could achieve monetary independence with financial integration, but sacrifice exchange-rate stability. The results clarify that currency exchange shocks in one country can cause a persistent rise in the volatility of other countries’ foreign exchange markets. These results show that the Central Banks in SADC countries will need to take policy actions following a large exchange rate shock. Therefore, the results on the exchange-rate volatility theme are useful for policy makers to formulate and implement appropriate policies in the event an adverse shock is observed in SADC exchange markets where contagion/spill over effect is empirically manifested. Even though a rise in short-term interest rates could reduce the EMP, it could also further raise the fluctuations of short-term interest rates. Stabilising the EMP through manipulating short-term interest rates will often heighten volatility of interest rates for an extended period. The assumption that changes in the exchange rate affect the competitiveness of a firm, thus influencing the firm’s earnings, net worth, and stock prices was not supported by the results of this study for the period under analysis. However, the results concur with the portfolio theory that stock prices Granger-cause the exchange rates. This might mean that there is high movement of investors’ money between the South African stock markets and that of other countries. This will have significant influence on the demand for and supply of the South African Rand, which often is in disequilibrium. The policy implication is that the Central Bank should pay more attention to stabilising exchange rates against the major currencies. The results of this study have critical implications for monetary authorities (Central Banks) and decision-makers in business.

- Description: This study analysed the impact of external shocks on macroeconomic performance and policy responses in Zimbabwe for the period spanning from 2009 to 2016. The study was motivated by the rising global economic vulnerabilities following the global economic and financial crisis experienced between 2007 and 2009. The study was also in response to the concern by the Zimbabwean government that external shocks had become increasingly important in influencing macroeconomic developments in Zimbabwe. In view of the intensifying debate on external shocks, the study, therefore, sought to understand the impact of external shocks on economic performance and policy responses in Zimbabwe. The study contributes to empirical literature by assessing the relative contribution of external shocks in explaining business cycles, the main transmission mechanisms of the macroeconomic shocks in Zimbabwe, the extent to which shocks in Zimbabwe were synchronised with shocks affecting other regional countries and how effective were government policies in mitigating the impact of shocks in Zimbabwe. Zimbabwe is a fascinating case study given its unique exchange rate arrangements under the multiple currency system. The application of the micro-founded DSGE models in addition to the Structural Vector Autoregressive (SVAR) models is also a novel approach. The results of the DSGE model demonstrated that foreign output shocks and imported inflation were not important in accounting for developments in endogenous variables in Zimbabwe. In addition, the domestic output and inflation did not respond to a domestic monetary policy shock. However, the international commodity price was found to have some bearing on domestic output. Foreign interest rates had a positive effect on domestic interest rates. On the other hand, domestic variables did not respond to domestic interest rate movements. This effectively implies that whilst foreign interest rates influenced domestic interest rates, domestic interest rates did not influence real economic activity. In other words, the transmission mechanism was not from domestic monetary policy to real economic variables. The results of the SVAR model also confirmed the results obtained from the DSGE model. The results from the analysis of the synchronicity of shocks also provided very important information on the dynamics of external shocks and economic performance in Zimbabwe. These results pointed to the fact that although countries in the region experienced similar shocks, economic fluctuations were not synchronised implying that the shocks could be emanating from the domestic sources rather than external sources. The results from the analysis of the role of external shocks in explaining macroeconomic fluctuations in Zimbabwe revealed that domestic factors contribute more to macroeconomic fluctuations in Zimbabwe compared to external variables. The contribution of climatic factors to domestic output fluctuations was, however, found to have a limited or minimal impact on the economy. Regarding the monetary policy effectiveness, the study observed that there was a weak link between interest rates and output and inflation developments in Zimbabwe. The results also suggested a week link between interest rates and money supply in the economy. The results, however, suggested that international oil prices were very important in the domestic price formations, accounting for about 20 percent of the variation. The monetary policy conditional index on the other hand indicated that monetary conditions in the economy did not influence inflation and output developments, implying ineffectiveness of monetary policy. The results from the study demonstrated the fact that although external shocks do affect economic activity in Zimbabwe, domestic factors are more significant in influencing macroeconomic activity. The policy implication of the findings is that there is need to consider the domestic factors, which are more significant compared to the external factors. However, since monetary policy is not effective under the multiple currencies system, fiscal policy is important to deal with external shocks. This will also enable the economy to absorb the impact of external shocks into the economy. The policies should focus more on reducing the over-reliance on primary commodities for exports through diversification of the economy.

- Description: The process of trade liberalisation and market-oriented economic reforms was initiated in many developing countries in early 1980s; and it intensified in 1990s. In 1994, Cote d’Ivoire was assisted by the IMF to implement trade-policy reforms under Structural Adjustment Programme (SAP). After adopting SAP, the country witnessed soaring balance-of-payment problems, contraction of output, unemployment and the loss of government revenue. Several factors, which were at play resulted in dismal economic performance under SAP. In order to consolidate gains in competitiveness, and achieve high and sustainable growth, the Ivorian authorities coordinated efforts to establish and intra-regional custom tariffs among the member of the West African and Monetary Union (WAEMU), the Economic Community of West African States (ECOWAS), World Trade Organisation (WTO), Economic Partnership Agreements (EPAs) and bilateral agreements. It is against this background that this study is undertaken, in order to evaluate the impact of different trade-policy regimes on trade, welfare and revenue in Cote d’Ivoire. This study used one model: World Integrated Trade Solutions/Software for Market Analysis and Restrictions on Trade (WITS/SMART). The WITS/SMART model was used because of its ability in analysing the tariff effect of a single market on disaggregated product lines. The model also has the capability to analyse the effects of trade-policy reforms in the presence of imperfect substitutes. Using the WITS/SMART model, the study considered seven trade-liberalisation frameworks for Cote d’Ivoire: full implementation of the ECOWAS free trade agreement (FTA), ECOWAS common external tariff (CET), WAEMU CET, WAEMU FTA, EPAs, BFTAs and WTO FTA. The WITS/SMART model reveals that all trade liberalisation scenarios may cause welfare gains – due to the plummeting of prices. However, in all trade liberalisation scenarios, welfare gains were found to be is insignificant. In all cases, welfare gains fell far short of compensating for revenue loss. The impact of trade liberalisation on exports and imports was met with mixed reactions. For the WAEMU customs union and the ECOWAS customs union, and WTO FTA, trade reforms are likely to face serious balance-of-payment problems, as imports exceeded exports by significant margins. With respect to revenue loss, of all trading arrangements, the WTO FTA presents a serious challenge for Cote d’Ivoire revenue followed by BFTAs, ECOWAS FTA, EPAs, ECOWAS CET, WAEMU CET, and WAEMU FTA with anticipated revenue losses. Another challenge for Cote d’Ivoire is the presence of trade creation effects, which were observed in all trade reform scenarios. From this study, it appeared that WAEMU CET poses serious threats of trade creation followed by WTO FTA, BFTA, SADC FTA, COMESA CET, SADC CET, EPAs and WAEMU FTA. Specifically, the study highlighted that Cote d’Ivoire, on balance loses out on trade liberalisation, mainly from revenue loss and possible de-industrialisation from trade-creation effects. The study has also revealed that Cote d’Ivoire offers excessive tax exemptions, which worsens the fiscal position of the country in the face of trade liberalisation. Hence, based on the findings, this study recommends that Cote d’Ivoire needs to call for the design of a financial facility aimed at assisting industries affected by trade-creation effects. The country needs to consider improving the collection of revenue from alternative sources, such as VAT, excise duties, personal and company taxes and excise duty, in order to cushion itself against the revenue loss impact of trade reforms. Government could also consider widening the tax base, by taxing the informal sector, which has been growing rapidly in the past years. In addition, policies aimed at exports promotion, such as export subsidies, trade finance and the strengthening of trade-promotion organisations should be considered. The outcome of this study provides a wake-up call to developing countries engaged in the WTO negotiations and other regional trading arrangements.

- Description: This study examined the impact of trade liberalisation on Kenya. It analysed the influence of trade liberalisation on trade creation, trade diversion, exports, imports, revenue effects and welfare effects. The developments in trade liberalisation and free-trade economic arrangements were introduced in Kenya and many developing countries in the early 1980s and strengthened from 1990s onward. The short term effects of the structural-adjustment programs were characterised by poor balance of payment conditions, high levels of unemployment, contraction of the imports from other countries, and government revenue losses, among other social problems. Notwithstanding the dismal performance of the Kenyan Economy after liberalisation, the Kenyan government continued to liberalise its trade under various frameworks such as the Economic Partnership agreements (EPAs) with the European Union, the World Trade Organization (WTO) and various bilateral free-trade agreements (BFTA) with its largest trading partners. This study used the World Integrated Trade Solutions-Software for Market Analysis and Restrictions on Trade (WITS/SMART) using 2008 as the base year. This method was used mainly because of its strengths to analyse the tariff effects of a sole market on disaggregate product lines. In addition the WITS/SMART model is able to analyse the impact of trade liberalisation in scenarios of imperfect substitutes. Hence, this study used the WITS/SMART Model to examine the trade liberalisation framework for Kenya under comprehensive implementation of COMESA customs Union, COMESA FTA, WTOFTA and the EPAs. The comparative valuation of the trade-creation effects reveals that the WTOFTA expected the highest trade-creation effects of US$995.16 million. This was followed by the various bilateral free-trade agreements which had a trade-creation effect of US$333.04 million, then COMESACU which had a trade-creation effect of US$310.50 million followed by the EPAs with a value of US$129.45 million. COMESA FTA was expecting trade-creation effects valued at US$15.51 million. These trade-creation effects are expected to cause unemployment through de-industrialisation. This study has also noted that WTO FTA and COMESA CU had no evidence of trade diversion. However, BFTA, EPAs and COMESA FTA showed evidence of trade diversion of US$134.88 million, US$89.28 million and US$2.61 million respectively. This study also examined the possible revenue effect from the free-trade agreements and customs union. It was noted that most losses emanated from the WTOFTA, which was valued at US$817.15 million. This was followed by the COMESACU protocol, which is expected to register a loss amounting to US$327 million. The third free-trade agreement with the highest losses comprised the various BFTAs amounting to US$304 million. The forth probable losses were anticipated from EPAs amounting to US$142 million. The free-trade agreement with the least losses is COMESA FTA with an expected loss of US$7.88 million. The consumer welfare effect was done to assess if consumers benefitted from trade agreements. This study observed that the WTOFTA expected the highest consumer welfare effect of US$103.98 million. This was followed by the various COMESACU with an expected consumer welfare effect of US$56.27 million. The BFTA were the third with a consumer welfare effect of US$ 41.82 million. This was followed by the EPAs with a consumer welfare value of US$ 17.56 million. The trade protocol with the least-expected consumer-welfare effect was the COMESA FTA valued at US$ 1.60 million. Although welfare gains resulting from the anticipated trade agreements were an indication of potential benefits to Kenyans, they were insignificant. This study also analysed the export performance from five different trade agreements and their impact on Kenya. The BFTA expected an export value US$4.63 billion, followed by the EPAs with an expected export value of US$2.18 billion. The third largest export values was WTOFTA with an export value of US$12.12 billion, the fourth being COMESAFTA having an export value of US$ 434.28 million and finally COMESACU with an expected export value of US$394.14 million. The study showed that major exports were composed of minerals, tobacco and agricultural products dominating the export basket. The export destinations were expected to be the WTO members, which include Uganda, Congo, Egypt, Rwanda, Sudan and Zambia. Kenya expected an increase in imports mainly from the WTO amounting to 8.95 per cent. This was followed by the BFTA rated with an expected 3.2 per cent growth in imports. The third protocol expecting import growth was the COMESACU of 2.8 per cent import growth and the EPA with 1.16 per cent import growth, and finally, 0.07 per cent import growth from the COMESA FTA. The expected increase in imports is anticipated to create balance of payment problems for Kenya. The results of the study show that the welfare gains from trade liberalisation were not able to compensate for the revenue losses. The study also showed that Kenya was not able to make optimal use of trade liberalisation to expand its export destinations; as the COMESACU was expected to reduce exports. In light of these findings, the study recommends that measures aimed at boosting exports like strengthening of the Export Processing Zones, export subsidies, the establishing of supply-side facilities, trade financing plus strengthening of the export-supporting institutions. It is important to note that the findings of this study provide an opportunity for Kenya, and other developing countries, to implement measures to ensure that they achieve optimal benefits from the various regional trade agreements.

- Description: This study examined the impact of trade liberalisation on Kenya. It analysed the influence of trade liberalisation on trade creation, trade diversion, exports, imports, revenue effects and welfare effects. The developments in trade liberalisation and free-trade economic arrangements were introduced in Kenya and many developing countries in the early 1980s and strengthened from 1990s onward. The short term effects of the structural-adjustment programs were characterised by poor balance of payment conditions, high levels of unemployment, contraction of the imports from other countries, and government revenue losses, among other social problems. Notwithstanding the dismal performance of the Kenyan Economy after liberalisation, the Kenyan government continued to liberalise its trade under various frameworks such as the Economic Partnership agreements (EPAs) with the European Union, the World Trade Organization (WTO) and various bilateral free-trade agreements (BFTA) with its largest trading partners. This study used the World Integrated Trade Solutions-Software for Market Analysis and Restrictions on Trade (WITS/SMART) using 2008 as the base year. This method was used mainly because of its strengths to analyse the tariff effects of a sole market on disaggregate product lines. In addition the WITS/SMART model is able to analyse the impact of trade liberalisation in scenarios of imperfect substitutes. Hence, this study used the WITS/SMART Model to examine the trade liberalisation framework for Kenya under comprehensive implementation of COMESA customs Union, COMESA FTA, WTOFTA and the EPAs. The comparative valuation of the trade-creation effects reveals that the WTOFTA expected the highest trade-creation effects of US$995.16 million. This was followed by the various bilateral free-trade agreements which had a trade-creation effect of US$333.04 million, then COMESACU which had a trade-creation effect of US$310.50 million followed by the EPAs with a value of US$129.45 million.

- Description: How a country is perceived by foreign investors is becoming increasingly significant to the ability of individual countries to attract foreign direct investment into their economies. In Africa, existing negative perceptions of the continent as an investment destination have been considered as an obstacle for foreign direct investment inflows to the continent in general. Although Zimbabwe offers foreign investors multiple lucrative investment opportunities, attracting foreign direct investment to the country presents a unique challenge due to the image of the country post the 1998-2008 economic crisis. Despite the vast research on the determinants of foreign direct inflows to particular countries, little is known about whether non-financial image-related factors influence the inflow of foreign direct investment to a particular country, especially a country with a unfavourable global image like Zimbabwe. The primary objective of this study was therefore to determine the perceived non-financial nation brand image factors considered to be influential for attracting specific foreign direct investment inflow opportunities in Zimbabwe. A comprehensive literature review resulted in the identification of nine independent variables (tourism, governance, people, culture and heritage, exports, investment and immigration, factor endowments, infrastructure, and legal and regulation frameworks), as well as four dependent variables (market-, resource-, efficiency- and strategic asset-seeking foreign direct investment inflow opportunities in Zimbabwe). A hypothesised model was developed in order to examine whether the independent variables have an influence on the dependent variables, and as a result nine hypotheses were formulated to test the relationships between the nine independent variables and each of the four dependent variables. A cross-sectional, quantitative deductive approach to research was employed in order to generate the data required for hypothesis testing. Purposive sampling techniques were employed to draw the sample frame for the study. A self-administered online survey was conducted, and generated empirical data from a final sample comprised of 305 investors who had applied to invest in Zimbabwe through the Zimbabwe Investment Authority between January 2009 and April 2015. Data was analysed using STATISTICA 12 software. Exploratory factor analysis was utilised to extract the constructs and validate the measuring instrument. Cronbach’s alpha coefficients were calculated in order to test the reliability and internal consistency of the measuring instrument. As a result, a total of six valid and reliable independent variables, and four dependent variables were retained for further analysis. The results of the Pearson product-moment correlation coefficients revealed mostly moderate correlations. The Multi-Collinearity diagnostics test confirmed the absence of collinearity between the independent variables and dependent variables respectively. Subsequently, the results of the four sets of multiple regression analyses, disclosed thirteen statistically significant relationships between the six independent variables and the four categorical dependent variables. Tourism had significant relationships with market-, efficiency- and strategic asset-seeking FDI inflow opportunities. Government actions had significant relationships with resource- and strategic asset-seeking FDI inflow opportunities. People had significant relationships with resource- and efficiency- seeking FDI inflow opportunities. Export had significant relationships with market-, resource-, efficiency- and strategic asset-seeking FDI inflow opportunities. Regulatory framework had significant relationships with market- and resource-seeking FDI inflow opportunities. The results of the Analysis of Variance revealed that investor status can be used to predict which non-financial nation brand image determinants played a role in the ultimate decision for taking up foreign direct investment opportunities in Zimbabwe. Further analysis of the role that the demographic profiles of the investors played in predicting which non-financial nation brand image determinants are considered influential in taking up foreign direct investment opportunities in Zimbabwe was confirmed in the Multivariate Analysis of Variance with thirty-four statically significant relationships identified. Further analysis by means of post-hoc Scheffé testing and Cohen’s d-values calculations confirm that thirty-nine practically significant mean differences were evident. This study makes a novel contribution to the empirical body of nation branding, foreign direct investment and investment promotion research by developing and testing a hypothetical model that synthesises facets of the three fields of study. This study represents a new discourse in the identification of the determinants of FDI (that being non-financial determinants) and provides an explanatory framework for the non-financial nation brand image determinants influencing each type of FDI inflow opportunity sought in Zimbabwe. It is within this framework that recommendations, based on empirical evidence, are made for the Government of Zimbabwe and the Zimbabwe Investment Authority. Some of these recommendations could be implemented within the short-term, while others may be more strategic in the long term. Recommendations made include that the Government of Zimbabwe undertakes significant policy reviews, continues its engagement with key external stakeholders such as other governments, supra-national financial institutions, and foreign investors, as well as adhering to existing favourable FDI policies. It is also recommended that the Zimbabwe Investment Authority adopt an intermediary role, by linking the Government of Zimbabwe with potential foreign investors through investor targeting, as well as promoting Zimbabwe as an investment destination by engaging in image-building activities such as public diplomacy, investor relations, specialised advertising and hosting investor forums with multiple, distinct investor segments. These image-building activities should be centered on the non-financial nation brand image determinants that foreign investors consider to be influential to foreign direct investment in Zimbabwe, and should be geared towards improving and managing the perceived image of Zimbabwe as an investment destination.

- Description: The aim of this study was to describe occurrences of peer harassment and the influences it has on Form Three learners in Zimbabwean rural day secondary schools. A review of studies conducted internationally indicated that peer harassment is prevalent and is stressful for most learners. Reports indicate that the negative impacts of peer harassment limit the educational achievements of the learners, and that learners need teacher and parental assistance to deal with peer harassment. In particular there appears to be a need for the creation of safe learning environments. This study was informed by an eclectic framework based on Erik Erikson's psychosocial theory, Bronfenbrenner's socio-ecological theory and Allardt's social welfare theory. These three theories point to the need for understanding that the social supports available to an individual determine how the individual perceives and responds to all his or her experiences. Investigations of the perceptions which individuals hold of their diverse lived experiences are best understood from a qualitative paradigm. Since the study intended to gain an understanding of the forms of peer harassment experienced by learners and how their individual experiences influenced their wellbeing, a phenomenological design was used. The sample was comprised of fifteen Form Three (grade 10) learners from three rural schools who volunteered to share their experiences of peer harassment. Data generated from semi-structured interviews with the individual participants were analyzed revealing emergent themes to answer the research questions. Findings revealed that the learners experienced various forms of peer harassment with physical peer harassment being the most prevalent. The data also revealed that peer harassment had both psychological and social influences on the well being of the learners which were primarily negative. Most learners felt that they were not getting adequate support from the adults (i.e., their teachers and the parents and guardians. The apparent reason for this lack of support from the adults was related to the community values which adults held about how learners were expected to deal with peer harassment. It was also evident that most learners chose to suffer silently, or hoped that God would intervene to assist them. Teachers were also not doing enough to assist the learners to stop peer harassment. Like the parents and guardians, most of the teachers did not perceive peer harassment as a serious problem in learners' lives so they did very little to assist victims who complained to them. Learners relied primarily on friends for support. The study concluded that peer harassment influenced the learners 'psychological and social well being negatively. It provided recommendations for schools, teachers, parents and the learners themselves. These stakeholders may collaborate to establish anti-harassment policies and to inform the design and implementation of anti-harassment policies in Zimbabwean rural schools. Recommendations are also provided for further studies aimed at identifying effective responses to the phenomenon of peer harassment.

- Description: The construction industry is known as a very highly-fragmented industry with a large number of activities involving different parties and professionals such as project managers, architects, engineers, quantity surveyors, contractors, suppliers and financiers. As it is a fragmented industry, management efficiency and competency in the industry is needed to gain a higher level of competitiveness. Although it is often clear what the causes and effects of construction projects delays are, little attention has been given to the role of management in the causes, effects and incidence of construction project delays. This research fills this gap in the literature. For the study, a theoretical framework to investigate the role of management in the causes, effects and incidence of construction project delays was developed. The framework showed how four management functions predicted the causes, effects and incidence of construction project delays. Nine factors were identified as the causes of construction project delays, namely, clients, contractors, labour, equipment, materials, consultants, community, contract and external issues. For the study, three effects of delays were proposed, namely, finance related delays, human related delays and legal related delays. In addition, the incidence of delays included the frequency of delays and duration of delays. This framework was empirically tested, and partial correlations were used to test the four hypotheses of the study. Three of the four hypotheses were accepted while the forth one was only partially-accepted. It was determined that demographics significantly predicted organising and leading of contractor managers in construction project delays. More specifically, demographics influenced how contractors with different educational levels executed organising and leading in managing construction project delays. The results further showed that management functions employed in construction projects, predicted five of the nine causes of construction delays. Further, the causes of construction project delays predicted both frequency and duration representing the incidence of construction delays. Lastly, the causes of construction project delays predicted the financial, human and legal effects of construction delays. The empirically-tested framework produced only two factors causing construction project delays. Factor one included variables relating to contractor and consultant related issues, and factor two included community, contractual and external issues. The factors for the effects of construction project delays and incidence of construction project delays remained the same. Respondent contractors in this study indicated that education was important as it influenced both leadership and organising functions of these contractors. Age, sex and other demographics did not influence the management functions for these contractors. Although much has been written on the causes, effects and incidence of construction project delays, very little attention has focussed on the role of management in these. For the respondent contractors who were included in the research, the two management functions that would influence the causes, effects and incidence of construction project delays, included organising and leadership. It further showed that these contractors were adequately dealing with planning and controlling, but needed to pay attention to organising and leadership.

- Description: Psychobiography can be viewed as the re-writing of an individual‟s life story previously undetected. In general, it consists of a combination of two central elements: biography and psychological theory, which aim to explain the particular individual‟s psychological development. This particular study serves to explore the extraordinary life of renowned singer and songwriter, Ian Kevin Curtis (1956-1980), who died by suicide at the early age of 23. The basis for this investigation will take the form of notable biographical accounts of the subject‟s life, together with the application of Thomas Joiner‟s (2005) interpersonal-psychological theory of suicide which identifies factors that lead to suicidal ideation - in an attempt to understand the psychological circumstances that contributed to Curtis‟s suicide. In doing so, Adler‟s (1929) theory of Individual Psychology was applied to the life of Curtis in an attempt to build on Joiner‟s theory. This led to the concept of control being introduced and contributed to the development of an intake form to identify those at risk for suicide. It is hoped that exploring the psychological circumstances that contributed to Curtis‟s suicide and their interpretation by the subject will bring about an understanding of the risk factors that may induce suicide and, by extension, will highlight the relevance of this psychobiographical study as a tool for investigating and promoting preventative measures concerning suicide. The psychobiographical data collection and analysis for this research thesis will be guided by Yin‟s (2003) theory of „analytic generalisation‟ which uses a theoretical framework in selecting relevant data which develops a matrix as a descriptive framework for organising and integrating that data, and Alexander‟s (1988) analytical model which focuses on lifting out themes through principal identifiers of salience.

- Description: Psychobiography can be viewed as the re-writing of an individual‟s life story previously undetected. In general, it consists of a combination of two central elements: biography and psychological theory, which aim to explain the particular individual‟s psychological development. This particular study serves to explore the extraordinary life of renowned singer and songwriter, Ian Kevin Curtis (1956-1980), who died by suicide at the early age of 23. The basis for this investigation will take the form of notable biographical accounts of the subject‟s life, together with the application of Thomas Joiner‟s (2005) interpersonal-psychological theory of suicide which identifies factors that lead to suicidal ideation - in an attempt to understand the psychological circumstances that contributed to Curtis‟s suicide. In doing so, Adler‟s (1929) theory of Individual Psychology was applied to the life of Curtis in an attempt to build on Joiner‟s theory. This led to the concept of control being introduced and contributed to the development of an intake form to identify those at risk for suicide. It is hoped that exploring the psychological circumstances that contributed to Curtis‟s suicide and their interpretation by the subject will bring about an understanding of the risk factors that may induce suicide and, by extension, will highlight the relevance of this psychobiographical study as a tool for investigating and promoting preventative measures concerning suicide. The psychobiographical data collection and analysis for this research thesis will be guided by Yin‟s (2003) theory of „analytic generalisation‟ which uses a theoretical framework in selecting relevant data which develops a matrix as a descriptive framework for organising and integrating that data, and Alexander‟s (1988) analytical model which focuses on lifting out themes through principal identifiers of salience.

- Description: The phenomena that we collectively refer to as “play” form a significant part of life at numerous levels. According to the play scholar, Johan Huizinga, play has not only been part of all human societies, it is also at the root of the development of numerous cultural activities, including structured games and sports, certain judicial and legal activities, war, and numerous forms of art. Despite its importance, play, with its various manifestations, is often relegated to being a children’s activity or an occasion of pure waste, and is a surprisingly marginalized topic in academic scholarship. In part to remedy this deficit, my aim in this thesis is to explore the comparatively new phenomenon of video games as a particular form of play. While there are undoubtedly many philosophical approaches that can respond to different aspects of the “problem” of video games, I propose that Gilles Deleuze and Felix Guattari’s philosophy of “difference” and “becoming” is particularly useful. On the one hand, Deleuze and Guattari’s philosophy provides a viable framework through which to determine the limitations of the current prominent theories in the field of video game studies, which include “narratology”, “ludology”, and the more recent “hybrid approach”. On the other hand, their philosophy enables one to extend the creative and transformative potential that is inherent to a philosophical “problem”, in this case the “problem” of video games. By adapting selected Deleuzian and Deleuzoguattarian philosophical concepts, including “assemblage”, “percept”, “affect”, “transversal becoming”, and “becoming-imperceptible”, I aim to establish a philosophical framework through which different forms of play, and different video games, can be analyzed in terms of their capacity to generate “difference” and “becoming”. More specifically, I argue that video games can be understood as particular kinds of “play assemblages” that can potentially open the player to “transversal becomings”. The video games that I analyze as play assemblages that can generate “transversal becomings” are Thatgamecompany’s Flower (2009) and Journey (2012). Importantly, “transversal becomings”, understood in this instance as the “becoming-other” of human individuals, have the potential to contribute to the individual’s capacity for creative thought and action. Therefore, I argue that video games, far from being activities of pure waste, can potentially open the player to various forms of “becoming-other”, which can, in turn, increase the player’s capacity to think differently, to become different and to create differences. Ultimately, I aim to promote the value of play and video games on the one hand, and the value of Deleuze and Guattari’s philosophy on the other hand, for the aim of extending the questioning power of life, and increasing our capacity to effectively respond to a continuously changing world of problems.

- Description: The arena for finding an intimate partner has changed significantly in the 21st century with online love relationships becoming more prevalent. Research indicates that individuals do experience meaningful online romantic love relationships and that these relationships often lead to face to face (FTF) relationships. However, limited research has been done on exploring the experiences of those who are/were involved in online romantic love relationships. Furthermore, research conducted on online love romantic relationships generally fails to investigate how people experience passion online, hereby ignoring this integral component of romantic love. The primary aim of the research study was to explore young adults’ experiences of romantic love relationships in virtual space. More specifically, the study explored how young adults experienced intimacy and passion as elements of romantic love online. The study was viewed from an interpretative paradigm and made use of a qualitative approach. The researcher conducted in-depth, semi-structured interviews with seven participants which were transcribed, and analysed using Interpretative Phenomenological Analysis (IPA). Four superordinate themes were identified, namely, Online Intimacy, Online Romance and Passion, Online Love, and Social Exchange Online. The participants experienced romantic love online and reported that these relationships were very significant, real and impacted on their psychological well-being. The study created a heuristic base that will provide impetus for this emerging field in research.

- Description: The main purpose of this study is to provide a critical analysis of selected literary techniques in P.T. Mtuze’s prose narratives. This study seeks to analyse his style of writing in all his texts. The aspects of his style under stylistic techniques and criticism will serve as a foundation theory that will link the study to the analysis of definitions and referencing under imagery and its aspects; including humour, satire, idioms, proverbs, literary techniques, and figures of speech. Mtuze is noted as one of the most prolific writers due to his ingenuity in language skills, especially in isiXhosa. Mtuze is one of the best humoristic writers; hence he is popular due to applying humour in the prose works he wrote. This study is divided into seven chapters, and the theory which is used for this study is also scrutinised in order to get a sense of what the author intended to deliver through his texts.

- Description: The debate on how the communication function can contribute at a strategic level to organisational success is an on-going one because communicators still need to prove their relevance at the top management level. In general, the contribution of communication as a management function in corporate strategy is not known. It is either considered an afterthought or as an element within other functional departments. In this regard, the purpose of this study was to analyse critically the role of communication in strategic planning at the selected South African universities. To achieve this main objective, institutional theory was applied, as it seeks to affirm the role of communication in decision-making with the intention to be legitimised. In-depth interviews were conducted with senior communicators and strategy planners at six universities on how they approach strategic planning in their respective universities. Significant from the findings was the fact that the South African universities follow the same process for strategic planning. Regarding the role of strategic communication, the findings confirmed literature in the sense that communication practice at functional level has been institutionalised but not at the top management level. It was this study’s finding that university reputation and positioning did not prominently feature in the strategic planning processes. Furthermore, this study found that communicators should play a leading in environmental scanning to identify society, industry and commerce with a view to fine-tune the university’s qualification mix. That is, communicators should provide intelligence on changes in the environment which serve as the basis of the development of university strategies. In other words, they should provide vital information to top management to enable them to take informed strategic decisions. Lastly, it was this study’s finding that communicators should conduct evaluation research to assist top management in comparing the set strategic objectives with actual performance. In addition, the communicators should assist top management in determining corrective actions if need be. In view of these findings, this study developed guidelines that will empower communicators to make a more meaningful contribution in the strategic planning process. Given the paucity of research evidence of strategic communication in a university context, the study provides a better understanding of the theory and practice thereof.

- Description: Information and communication technologies (ICTs) have been widely researched as a mechanism for improving the socio-economic status of disadvantaged, rural communities. In order to do this numerous technology-based initiatives have been introduced into disadvantaged, rural communities to assist them in various aspects of their lives. Unfortunately, even when the proposed benefit of a particular technology is clearly evident to its initiators, the adoption by the target users is often uncertain. This has also been the case with e-commerce in agriculture. Despite the numerous benefits of e-commerce for agricultural producers, the uptake has been low. Trust is a critical pre-condition for the adoption of e-marketplaces. E-marketplaces expose consumers to the risk of non-delivery or misrepresentation of goods ordered and the misuse of personal information by external parties. Additionally, the time investment needed to make a shift to e-marketplaces and the opinions of important reference groups affects the user’s willingness to trust and depend on an e-marketplace. This study was undertaken to assess the extent to which rural users with limited ICT experience would trust and, consequently, adopt an e-marketplace to support agricultural trade. A pragmatic philosophy was adopted in this study, indicating that the researcher’s view of reality is founded on the practical implications and outcomes that are observed. This study used a Canonical Action Research strategy to design, develop and deploy a voice based e-marketplace to assist the trading activities of a Western Cape based aloe community. The community was allowed to utilise thee-marketplace over a period of eight weeks. Thereafter, interviews were held with the participants to investigate their perceptions of the technology. As a result, a model proposing the factors that must be in place for trust to be achieved in a voice based e-marketplace was proposed. The study found that the trustworthiness of a technology results from the technology’s technical capability to satisfy the needs of its users reliably. Usability and security were found to be important determinants of the trustworthiness of a technology. Furthermore, the requirements elicitation process was found to be central to achieving trust as it defines the necessary criteria for developing secure, usable, functional, and reliable technologies that meet the needs of their users.
