- Description: The intention of this study was to measure the work engagement and EVP of employees and further to investigate the relationship between work engagement and EVP. A secondary objective was to determine to determine to what extend intrinsic rewards of EVP affects work engagement more than extrinsic rewards. The study was quantitative in nature and data was obtained by means of an electronic survey. The EVP questionnaire and UWES were used to measure EVP and work engagement respectively. Results showed that there is no practical relationship between work engagement and EVP; however, evidence suggested a statistically significant relationship between work engagement and EVP. There was no evidence to suggest that in the relationship between work engagement and EVP, intrinsic components of EVP affect work engagement more than extrinsic rewards. It was however suggested that although the extrinsic rewards component of EVP are important in attracting and retaining employees, rewards had no correlation with work engagement. Implications of the findings suggest that rewards might be important when attracting and retaining employees to a company. However, in order to develop levels of work engagement rewards play no significant role. Companies should invest in enhancing the intrinsic components of their EVP to such an extent that it contributes to levels of work engagement.

- Description: The citizens of a state make sense of political parties from what is communicated about the parties as well as how that message is communicated. The use of social media, as a campaign communication vehicle, by political parties and voters is increasing, which brings rise to the need to examine the role of social media in South African politics. This study, which is a necessary exploration of political communication in South Africa, particularly on social media post-1994, looks at the scope of political communication on social media pre and post the 2014 elections in South Africa. Through a content analysis, this study analyses the communication messages of political parties on Twitter and the public‟s response to those messages. Furthermore, drawing from the theories of Framing and Agenda setting, this study explores how issues are framed on social media as well as the agenda setting role of social media. The study also identifies the issues that present themselves in political communication through social media in South Africa, and proposes ways in which the political parties could campaign more compellingly and effectively on social media.

- Description: Businesses communicate a wide variety of messages to diverse audiences using a number of different communication types and channels daily. For example, business communication includes business reports, documents (booklets, leaflets, and official communiqués), notices, agreements, web copy and advertisements that are produced continually to address a variety of business communication needs for a variety of audiences. Although written business communication has a significant impact on customer satisfaction and consumer attitude which, in turn, affects consumer behaviour positively or negatively, there is a lack of research investigating the knowledge and application of plain language in business communication. Many studies were found to be related to communication and language, however, studies about plain language use were less prevalent. Therefore, this study aimed to investigate the awareness of the plain language regulations stipulated in the South African Consumer Protection Act (CPA) 68 of 2008 (2009). The application of these plain language principles within businesses in the Port Elizabeth Metropole, with specific reference to its use in written business communication was also investigated. The study also aimed to identify plain language best practices and constraints resulting from plain language application or non-application within the selected organisations. The research focused attention on the impact of business communication on customer satisfaction, consumer attitude and, ultimately, consumer behaviour as well as the need for plain language use in written business communication practices to ensure effective and fair (ethical) communication. A comprehensive literature review was conducted on communication, communication theory and consumer behaviour, as well as on plain language principles which might add to the effectiveness of organisations’ written business communication, to provide a theoretical foundation for the study. The study’s research methodology was approached from a phenomenological (descriptive and interpretive), and somewhat positivistic perspective, utilising qualitative and limited quantitative measures to obtain data. For this reason, three managers from three respective organisations within the Port Elizabeth Metropole were interviewed and asked to complete a rating-scale survey to obtain insight on the written business communication practices of these organisations. A content analysis of documents supplied by the participating organisations were also reviewed to provide commentary on the plain language application in each organisation. Furthermore, Section 2 of the South African CPA 68 of 2008 (2009) was also reviewed to measure and comment on the application of plain language in these organisations. Based on the data analysis, it was evident that organisations in the Port Elizabeth Metropole were aware of plain language and the plain language regulations stipulated in the South African CPA 68 of 2008 (2009), but that they were not certain what the regulations entailed exactly. Furthermore, plain language principles were applied in the participating organisations, however, complications and areas for possible improvement were identified in the data. From the study’s findings, various recommendations were made that could assist the organisations to improve their organisations’ plain language application. These recommendations included, for example, appointing plain language champions to monitor plain language application in the organisation, as well as assessing language competence of staff and training them to improve their language competencies. Recommendations for future research suggested that future studies needed to include a larger research sample, a more diverse sample population to include consumers and a broader industrial demographic. In addition, future studies could attempt to investigate communication barriers that inhibit or challenge comprehension in consumer communication.

- Description: The study introduces and demonstrates the viability of the continuous flow reactor (CFR) system for the production of bio-crude oil (BCO) from wet microalgae. Preliminary experiments conducted in the CFR system in hot compressed water (HCW) were successful in converting wet microalgae into liquid BCO. However, the synthesis and aggregation of high boiling point (HBP) components of BCO and the accumulation of char in the tubular piping of CFR system were identified as the limiting factor to the viability of the system. The aggregation of HBP components and the accumulation of char result to system blockage which prevents the continuous flow of the liquefaction product mixture in the CFR system. Inhibiting the reactions leading to the formation of HBP components and char will improve the performance of the CFR system. Therefore, the study seeks to incorporate co-solvents in the liquefaction reaction media in an attempt to inhibit or minimize the prevalence of HBP components of BCO. As such, different co-solvents were screened for their influence on improving the quality of BCO with respect to its boiling point profile (BPP), initial and final boiling point, as well as the amount of char recovered from each experiment. Only one co-solvent was chosen for further exploration in the CFR system. Batch liquefaction reactor’s (BLR) made up of stainless steel were used to carry out the co-solvent screening experiments. These experiments were carried out at a constant temperature (280 °C), pressure (75 bar), and co-solvent concentration (10 wt.%), at varying residence times. Solvent extraction with dichloromethane (DCM) was performed on the liquefaction product mixture to separate the products, viz. BCO, char and water soluble components. The extracted BCO was analysed through simulated distillation (SimDis) to obtain the BPP. The BPP properties of the BCO samples, from different liquefaction media, and the amount of char recovered were highly influenced by the addition of a co-solvent. The final boiling point (FBP) of tetralin, heptane, and n-octanol BCO products were significantly reduced to below 500 °C for all tested residence times except at 20 minutes. The residence time also proved to be influential in the processing of wet microalgae. n-Octanol was selected as the optimal performing co-solvent and was used for the continuous liquefaction of wet microalgae in the CFR system. The CFR system was modified by adding a co-solvent feed line into the continuous system since n-octanol was insoluble in water. The n-octanol pump was set at different flow rates, 0.2, 0.3, and 0.4 g/min, which resulted in a concentration of about 10 wt.% in the reactor feed. The concentration of n-octanol had a significant influence on the BPP of BCO components. The FBP’s were reduced with an increase in n-octanol concentration. The initial boiling point (IBP) of n-octanol BCO was increased to just above 100 °C which was required for the stability of the BCO product. The components of BCO were identified by GCMS. n-Octanol also proved to affect the composition of the BCO with respect to its components. HCW BCO components were significantly different from those identified from n-octanol BCO. A second co-solvent (tetralin) was used to prove whether the difference on the components of BCO was affected by n-octanol. The results proved that indeed the addition of different solvents in liquefaction reaction media favours the formation of different components. The amount of char formed was also reduced when using a co-solvent. A decrease in the oxygen/nitrogen compounds was also observed in the presence of a co-solvent, thus improving BCO properties.

- Description: This research project was aimed at investigating strategies that are used for the sustainability of selected rural-based community radio stations in the Transkei area of the Eastern Cape. The study was done under a hypothesis that, in the absence of big business and migration of literate people and skilled labour from rural communities to urban centres, rural-based community radios struggle to attract operational revenue through advertising, community support, etc., and that the supposedly high illiteracy in the rural areas render it difficult to run the stations. Two rural-based community radio stations were selected for this study: Alfred Nzo Community Radio at Mount Ayliff in the Alfred Nzo District Municipality area, and Vukani Community Radio at Cala in the Chris Hani District Municipality area. The aim was to study their activities with regard to the most and widely agreed three-dimensional method of sustaining community radio stations: Financial Sustainability, Institutional Sustainability, and Social Sustainability. Relevant literature has been reviewed and data have been collected using both quantitative and qualitative methods through questionnaires. The study however leans more on the qualitative approach and a quantitative approach has merely been used to identify the trends of the views of the participants. The analysis of data highlights the views of the respondents about these radio stations with regard to their strategies to sustain themselves. The views of the respondents represent all people from all levels of people involved in the stations: From the Member of the Board of Directors in the boardroom to stations’ members of management at their desks. From Presenters behind their microphones to the listener in the dusty streets of the poor rural areas. The results confirm the hypothesis that the areas have high unemployment and illiteracy rates, and that their sustainability depend largely on trade-outs with local business and government support. However, the study also shows that strategies for Financial Sustainability, Institutional Sustainability, and Social Sustainability may overlap or influence each other. For instance, an activity of Institutional Sustainability may result in Financial Sustainability, and visa-versa. The study also reveals that the stations struggle to establish and maintain effective Social Sustainability for the benefit of the station. In the light of this, a proposal for further study and recommendations are given at the end of the study.

- Description: This study sought to empirically investigate the existence of calendar effects and market anomalies on the JSE using monthly and daily closing prices of the ALSI, Top 40, Mid Cap and Small Cap index; as well as, daily closing prices on the Value, Growth and Dividend Plus index during the sample period 2002 – 2013. The anomalies analysed are the January effect, the weekend effect, the size effect, the value effect, and the dividend yield effect. The empirical analysis uses a number of MSAR with a different number of regimes and lag orders. The results from the investigation of the January effect show the non-existence of the January effect and the value effect on the JSE during the periods 2002 – 2013 and 2004 – 2013, respectively. However, the weekend effect was found significant in the Mid Cap and the Small Cap index, and the size effect was also found significant during the same period 2002 - 2013. Finally the results from a Granger causality test concluded that there is a relationship between the returns on the Dividend Plus index and the ALSI, effectively proving the existence of the dividend yield effect on the JSE between 2006 and 2013. Additionally, the anomalies found imply the opportunity for investors to make returns above buy-and-hold.

- Description: Judith Butler’s writings on gender ostensibly changed the way gender is considered with regard to an individual’s subjectivity. Her writings expressed a discursive parameter that changed the theoretical standpoint of gender from that of performance, to that of performativity. In short, the notion of gender became understood as a power mechanism operating within society that compels individuals along the heteronormal binary tracts of male or female, man or woman. Within the strata of popular culture, this binarism is seemingly ritualized and repeated, incessantly. This treatise examines how rock music, as a popular and widespread mode of popular music, exemplifies gender binarism through a notable ndrocentrism. The research will examine how gender performativity operates within the taxonomy of rock music, and how the message communicated by rock music becomes translated into a listener’s subjectivity.

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

- Description: Bacteriocins (BCNs) are ribosomally synthesized polypeptides or proteins with antimicrobial activity, produced by different groups of bacteria. Many lactic acid bacteria (LAB) produce BCNs with broad spectra of inhibition. The antimicrobial activity of BCNs against spoilage organisms (SPOs) has raised considerable interest in their application in juice preservation. The objectives of the study were to: (i) isolate, identify and screen BCN producing bacteria for antimicrobial activity against spoilage bacteria and fungi, (ii) optimize production of BCN from selected producers and (iii) investigate the industrial application of the BCN as a preservative in fruit juice. Eleven LAB strains of BCN producers were screened for antimicrobial activity. BCNs from Lactobacillus plantarum and Pediococcus pentosaceus 34 were the most effective against juice spoilage bacteria and fungi. The effect of medium components on bacteriocin production in L. plantarum and P. pentosaceus 34 was also determined. Clementine:Valencia (1:1) juice was used for the first time as the growth medium for L. plantarum and P. pentosaceus 34. The BCN from L. plantarum showed the highest activity and was, therefore, chosen for juice fermentation studies. The identification of L. plantarum was confirmed by biochemical tests, polymerase chain reaction (PCR) and sequencing of the recA gene. The highest BCN activity was observed for L. plantarum grown in De Man-Rogosa-Sharpe (MRS) and a combination of all supplements (i.e. peptone, MnSO4.H2O, Tween 80, glucose and whey), followed by MRS and Tween 80, peptone, MnSO4.H2O and MRS alone. MRS was a better medium for BCN production than juice [Clementine:Valencia (1:1)]. Size exclusion chromatography (SEC) was used to isolate the active L. plantarum BCN fraction which corresponded to an approximate molecular weight of 3.2 kDa and was proteinaceous in nature. Plantaricin structural genes (plnEF, plnJ, plnK, plnN) were detected in the L. plantarum strain by PCR and sequenced, and were chromosomally encoded as no plasmids could be detected. This implies that the BCN from L. plantarum is most likely a type of class IIa plantaricin which is responsible for the broad inhibitory activity observed. For the industrial application studies, L. plantarum BCN-containing cell free supernatant (BCNsup) added to “Ready to Drink” (RTD) Clementine:Valencia (1:1) juice at concentrations of 3 600 - 500 000 ppm decreased growth of SPOs, Lactobacillus acidophilus and Streptococcus thermophilus. At 250 000 ppm, the L. plantarum BCNsup achieved 5.3 and 6.8 log reductions of the L. acidophilus, after 24 and 48 h, respectively, which is larger than the USFDA (2001) requirement of a 5 log reduction in SPO activity, for preservation of fruit juices. However, there was a decrease in the activity when the BCNsup was applied to industrial (Valor) RTD juice (mango-orange) at decreasing concentrations of 100 000, 50 000 and 25 000 ppm. Organoleptic tests showed that the BCN did not alter flavor or taste of the juice and did not cause toxicity or allergic reactions. A food safety risk assessment was conducted in order to determine the Critical Control Point(s) [CCP(s)] at which the BCN could be applied to control identified microbiological hazards, and a Hazard Analysis and Critical Control Point (HACCP) plan was developed. This is the first report on the optimisation of L. plantarum BCN production in juice [Clementine:Valencia (1:1)], followed by inoculation into RTD juice (mango-orange), including a HACCP plan for the application of the BCN as a preservative in juice.

- Description: Historical ad hoc allocations of land for biodiversity conservation have led to a biased representation of habitat within the Cape Floristic Region, with Protected Areas concentrated in upland areas at high altitudes and on steep slopes. The field of Conservation Planning developed to ensure that allocations of areas to Protected status no longer result in such bias and rather promotes the persistence of biodiversity. This study reviewed a recent allocation of land to biodiversity conservation within Western Cape of South Africa, using both a quantitative and qualitative approach, to determine their value to biodiversity conservation. The area was previously used for commercial forestry but now has been allocated to conservation land-uses. The allocation was based on the area’s value to the forestry industry. The qualitative approach in this study engaged with relevant stakeholder groups to map priority areas, while the quantitative approach used available data on biodiversity features to map priority areas. Neither approach determined that the area allocated is in its full extent a priority for biodiversity conservation. This indicated that in the current era of Conservation Planning, Protected Areas are still being allocated in an ad hoc manner, as a result of their limited perceived benefit to anthropocentric needs. The future allocation of land to biodiversity conservation should rather integrate expert knowledge and available quantifiable data to ensure that priority areas for biodiversity conservation are being protected.

- Description: Critical care nursing is a clinical specialist nursing practice discipline. The critical care nurse provides a constant presence in the care of a critically ill patient. She/he creates a thread of continuity in care through the myriad of other health care professionals and activities that form part of a patient’s stay in the critical care environment (World Federation of Critical Care Nurses [WFCCN], 2007). During conversations with people who have had intimate experience of the critical care environment, they have offered anecdotes that describe their interaction with critical care nurses who they perceive to be different from and better than other critical care nurses they encountered. Despite having met common professional requirements to be registered as a clinical specialist nurse, these distinctive, unique abilities that seem to be influential in meeting the complex needs and expectations of critically ill patients, their significant others as well as nursing and medical colleagues, are not displayed by all critical care nurses. While students of accredited postgraduate nursing programmes are required to advance their nursing knowledge and skill competence, many students do not seem to develop other, perhaps more tacit, qualities that utilisers characterise in their anecdotes of ‘different and better’ nursing practice. The overarching research question guiding this study was how can ‘different and better’ critical care nursing practice as recognised by a utiliser be explained? The purpose of this study was to develop an understanding of the qualities that those people who use critical care nursing practice recognise as ‘different and better’ to the norm of nursing practice they encounter in this discipline. The participant sample included patients’ significant others, nursing colleagues and medical colleagues of critical care nurses, collectively identified as utilisers. The stated aim of this work was to construct a grounded theory to elucidate an understanding of the qualities that a utiliser of critical care nursing recognises as ‘different and better’ critical care nursing practice in order to enhance the teaching and learning encounters between nurse educators and postgraduate students in learning programmes aiming to develop clinical specialist nurses. The method processes of grounded theory are designed to reveal and confirm concepts from within the data as well as the connections between these concepts, supporting the researcher in crafting a substantive theory that is definitively grounded in the participants’ views and stories (Streubert & Carpenter, 2011: 123, 128-129). Two data collection tools were employed in this study, namely in-depth unstructured individual interviews and naïve sketch. Constant comparative analysis, memo-writing, theoretical sampling, theoretical sensitivity and theoretical saturation as fundamental methods of data generation in grounded theory were applied. The study unfolded through three broad parts, namely: Forming & shaping this grounded theory through exploration and co-creation; Assimilating & situating this grounded theory through understanding and enfolding; Reflecting on this grounded theory through contemplating and reconnecting. The outcome of the first part of the study was my initial proposition of a grounded theory co-created in the interactions between the participants and myself. This was then challenged, developed and assimilated through a focussed literature review through the second part of the study. Through these two parts of this study, an inductively derived explanation was formed and shaped to produce an assimilated and situated substantive grounded theory named Being at Ease. This grounded theory articulates how ‘better and different’ nursing is recognised from the point of view of those who use the nursing ability of critical care nurses through the core concern ‘being at ease’ and its four categories ‘knowing self’, ‘skilled being’, connecting with intention’ and’ anchoring’. The final part of this study unfolded in my reflections on what this grounded theory had revealed about nurses and elements of nursing practice that are important to a utiliser in recognising ‘different and better’ critical care nursing. I suggest that as nurses we need to develop a language that enables us to reveal with clarity these intangible and tacit elements recognised within the being and doing of ‘different and better’ nursing. I reflected on the pivotal space of influence a teacher has with a student, and on how the elements essential in being and doing ‘different and better’ nursing need to be evident in her/his own ways of being a teacher of nursing. Teaching and learning encounters may be enhanced through drawing what this theory has shown as necessary elements that shape ‘different and better’ nurses through the moments of influence a teacher has in each encounter with a student.

- Description: The earth has been undergoing a process of global warming and climate change for a period exceeding 100 years. These two occurrences have had many adverse effects on the sustainability of the environment as well as on humans and organisations. The direct cause of global warming and climate change, including the consequential negative ramifications, are due to humans use of natural resources mostly in the form of the consumption of products and services. Organisations are regarded as the largest consumers of products and services within society and as a result are responsible for the major contributions made to global warming and climate change. In order to rectify the negative impact made by organisations in terms of their ecological behaviour and ensure organisational sustainability theory, stipulates that a behavioural change within leadership is required. Ecologically intelligent leaders who hold an affirmation of an ecological worldview and enact pro-ecological behaviours are pivotal to the proliferation of ecological leadership and a subsequent rise in organisational pro-ecological behaviour, towards a sustainable future. On the basis of the above mentioned statements, gained from various literature, a conceptual model was formed and an exploratory research study undertaken to substantiate the presence of correlational or causal relationships between a leader’s ecological intelligence with the enactment of ecological leadership and organisational pro-ecological behaviour. The sample consisted of 42 respondents who occupied positions of leadership within organisations that were members of the Southern African Association for Energy Efficiency. The findings provide substantiating evidence of the presence of ecological intelligence within leadership, the enactment of ecological leadership as well as organisational pro-ecological behaviour. Furthermore significant correlational relationships exist between ecological leadership and organisational pro-ecological behaviour. There is also substantiating indication that the enablers of a leader’s ecological intelligence, an affirmation of an ecological worldview and pro-ecological behaviour, facilitate the outcome of organisational pro-ecological behaviour.

- Description: Cybercrime is the use of technology to support or directly facilitate a criminal activity, with logon credentials being the main information asset targeted during a cybercrime. The one time passwords used by banks to protect their clients from cybercrime are also under attack by cybercriminals. The Internet has made it easy to commit cybercrime, with perpetrators experiencing virtually no risk with huge returns. Individual cybercrime cases are sometimes small in nature, which means that the police can be reluctant to commit the resources necessary to investigate every incident. There is a distinct lack of resources, skills, knowledge and training in relation to identifying, understanding and responding to the growing threat of cybercrime. This research addresses how to solve these issues in South Africa in order for cybercrime to be tackled effectively and for perpetrators to be prosecuted.

- Description: Water quality and ecological integrity of estuaries reflect activities within the entire upstream catchment. Much emphasis has been placed on the response of estuaries to anthropogenic stressors through the use of monitoring programmes. Key to the success of these programmes is the use of indicators as they transform data into useful information. The ultimate aim of this study was to identify eutrophic symptoms in selected estuaries in the Gouritz Water Management Area (WMA) using a multi-metric classification method. The study sites included the permanently open Duiwenhoks, Goukou, Gouritz, and Kaaimans estuaries, as well as the temporarily open/closed Hartenbos, Klein Brak, Great Brak, Gwaing, and Goukamma estuaries. Initially, the “pressure” associated with all the estuaries in the Gouritz WMA was determined (e.g. total daily nutrient loads and changes in river inflow affecting flushing time) using long-term flow and water quality monitoring data provided by the Department of Water Affairs (DWA). Subsequently, the “state” of the selected estuaries was assessed using a variety of indicators, including: inorganic nutrients (~ N and P), phytoplankton, epiphytes and microphytobenthos. Estuaries with longer flushing time suggested greater vulnerability to eutrophication. For example, the Gwaing (281.11 kg DIN d-1; 78.85 kg DIP d-1) and Hartenbos (38.33 kg DIN d-1; 21.51 kg DIP d-1) estuaries generally received the highest daily inorganic nutrient loads. However, at the time of sampling, the Hartenbos Estuary had a longer flushing time (i.e. weeks) compared to the Gwaing Estuary (i.e. couple of days). Field data confirmed the greater vulnerability to eutrophication associated with longer flushing times, as the indicators measured in the Hartenbos Estuary exceeded all the proposed ‘thresholds’ of a eutrophic system (~ overall ‘Poor’ condition). The Great Brak Estuary (~ overall ‘Fair’ condition) provided an interesting example where eutrophic symptoms were only detected when assessing the microalgal primary producers (i.e. high biomass and low diversity). Furthermore, the need to distinguish between naturally and anthropogenically induced symptoms was highlighted. One such scenario was noted in the Kaaimans Estuary, where its natural hydro-morphological characteristics (i.e. steep banks, low river inflow, and deep/narrow channel) led to the possible exaggeration of its overall eutrophic condition, i.e. received a ‘Fair’ rather than ‘Good’ rating, arising from ‘Poor’ ratings for dissolved oxygen and benthic diatom diversity. Overall, this study demonstrated the importance of adopting a holistic approach when assessing the condition and trophic status of estuaries. Studies such as these allow for the detection of vulnerable and degraded systems, which can provide important information with regards to the identification of management priorities.

- Description: Water quality and ecological integrity of estuaries reflect activities within the entire upstream catchment. Much emphasis has been placed on the response of estuaries to anthropogenic stressors through the use of monitoring programmes. Key to the success of these programmes is the use of indicators as they transform data into useful information. The ultimate aim of this study was to identify eutrophic symptoms in selected estuaries in the Gouritz Water Management Area (WMA) using a multi-metric classification method. The study sites included the permanently open Duiwenhoks, Goukou, Gouritz, and Kaaimans estuaries, as well as the temporarily open/closed Hartenbos, Klein Brak, Great Brak, Gwaing, and Goukamma estuaries. Initially, the “pressure” associated with all the estuaries in the Gouritz WMA was determined (e.g. total daily nutrient loads and changes in river inflow affecting flushing time) using long-term flow and water quality monitoring data provided by the Department of Water Affairs (DWA). Subsequently, the “state” of the selected estuaries was assessed using a variety of indicators, including: inorganic nutrients (~ N and P), phytoplankton, epiphytes and microphytobenthos. Estuaries with longer flushing time suggested greater vulnerability to eutrophication. For example, the Gwaing (281.11 kg DIN d-1; 78.85 kg DIP d-1) and Hartenbos (38.33 kg DIN d-1; 21.51 kg DIP d-1) estuaries generally received the highest daily inorganic nutrient loads. However, at the time of sampling, the Hartenbos Estuary had a longer flushing time (i.e. weeks) compared to the Gwaing Estuary (i.e. couple of days). Field data confirmed the greater vulnerability to eutrophication associated with longer flushing times, as the indicators measured in the Hartenbos Estuary exceeded all the proposed ‘thresholds’ of a eutrophic system (~ overall ‘Poor’ condition). The Great Brak Estuary (~ overall ‘Fair’ condition) provided an interesting example where eutrophic symptoms were only detected when assessing the microalgal primary producers (i.e. high biomass and low diversity).

- Description: The prosperity of small micro and medium enterprises (SMME’s) in the construction industry is vital for the improvement of the South African economy. Unfortunately, the poor safety record of this industry negatively affects the sustainability of SMME’s and augments the loss of human lives. Owners and managers of SMME’s in the construction industry are usually financially fragile and unaware of the direct and an indirect cost associated with injuries that may result in potential profit loss and ultimately, bankruptcy. The construction industry continues to lead with high levels of fatalities and injuries compared to other industrial sectors. High levels of non-compliance with health and safety legislation in the construction industry necessitate creative interventions to improve health and safety standards. The objective of the research was to establish to what extent SMME’s comply with health and safety in the construction industry. Research was done by means of a survey questionnaire and the findings concluded that government laws are appropriate however the enforcing of such law needs attention. Furthermore, most owners are aware of the required legislation but the competitive nature allude that “that shortcuts are taken”.

- Description: The South African automotive industry is by no means a ―cut and paste‖ version of their overseas counterparts. The industry and the market are very complex. The historical background of the industry is such that companies have difficulty forming partnerships and joint ventures with bigger international conglomerates. The difficulty with this kind of mindset is that it is restricting growth and development of the nation as a whole. Globalisation is a future we cannot be avoided. Should the nation continue to reject it and embrace the mindset of countries in Africa, South Africa (SA) will continue on the path that the rest of Africa is heading, a path that leading to self-destruct and segregation. Even though SA is a developing country, it is in some areas as developed as many other first world countries. For a country to generate wealth it needs to be innovative and develop an entrepreneurial consciousness. A young country like South Africa needs creative thinkers and opportunists that can see into the future, seizing every opportunity, to grow and develop new ideas and business. In order for a country to grow it needs a leadership that is to nurture the baby of innovation. If South Africa wants to be part of the global village it need to develop a trade policy that welcomes trade and at the same time creates stable and sustainable jobs. The environment for investments needs to be cultivated in a problem-free and growth prone nation. This can only happen when the educational level of the nation is improved. The fact that so many skilled workers need to be imported creates tension in the labour market. People with talent need to have a reason to stay in the country. Their salaries should match that of their overseas counterparts. Furthermore, with the same skill level and work ethic, should have the same rewards and remuneration.

- Description: Music’s significant contribution to the holistic development of the young learner is uncontested and confirmed by views of seminal scholars, such as Nzewi 2003, Reimer 2003, Nussbaum 2001, Elliot 1994 and Merriam 1964, amongst others. As such, music education supports basic values of self-growth, self-knowledge and enjoyment. This study argues for the vital importance of music education in Grade R in the South African schooling system where teachers can successfully implement the curriculum. In post-apartheid multicultural and multi-musical South Africa music education in Grade R is the sole responsibility of the generalist Grade R teacher. However, due to inadequate training and minimal, unproductive in-service initiatives, the vast majority of Reception Year teachers assumingly do not have the required competences to teach music in a way that maximally enhances the holistic development of their learners. Findings revealed that teachers exhibited limited, if any, musical knowledge and per se, they are insufficiently skilled in the effective delivery of the curriculum in terms of music. This study acknowledges the need to equip in-service Grade R teachers with the required competences to effectively implement the national school and teach music with confidence. The lack of successful and effective continuing professional teacher development initiatives from the Department of Education and Department of Basic Education to assist Grade R teachers in teaching music, was a serious concern to me. This concern reinforced the motivation to embark on this project. In this thesis, I report on an intervention strategy aimed at enabling three Grade R practitioners at one peri- urban township school in the Eastern Cape to improve their music education competencies. These three Coloured ladies only held a Certificate in Early Childhood Development, rating at an NQF level 4 and 5. None of these practitioners had any prior music experience in music training, music making or music teaching. I utilised a Participatory Action Learning and Action Research (PALAR). PALAR combines research with development and is thus highly suitable when addressing multifaceted problems in rapidly changing environments, such as South Africa. In my study, the participants were thus actively involved in identifying problems and creating solutions. A number of collaborative interactions and qualitative data generation strategies such as Focus Group Interviews, Observations, Drawing, Interviews, Narrative Inquiry, Case Study and Reflective Journals were implemented. Findings indicated that the practitioners experienced transformation on both a professional and personal level as they discovered and tapped into their own innate musical competences. This enabled them to explore ways to teach music that enhanced the holistic development of their learners, developing them physically, cognitively emotionally, socially, and musically. Learners likewise benefitted from the intervention as they experienced social cohesion in a multicultural classroom and gained the fruits of music’s remedial impact and therapeutic value in their lives.

- Description: The discussion on the extent to which audit committees perform the oversight function of financial governance is important. This is particularly so in the Eastern Cape where the implementation of the Public Finance Management Act (PFMA) of 1999 has not significantly improved financial management. The deteriorating financial management environment of provincial departments impacts negatively on service delivery and is therefore a matter of great concern to the political administrators at both national and provincial levels. The objective of this study is to determine how effective audit committees are in Eastern Cape provincial departments and how this translates into good financial governance and, ultimately, improved service delivery. To achieve this objective, a literature review of the link between audit committee effectiveness, accountability and corporate governance in the public sector was conducted. It was found that audit committees in the public sector have similar responsibilities to that of the private sector and lack of accountability in the public sector impacts negatively on service delivery. A second literature review was conducted to highlight the current state of public financial management in South Africa and how this has had an impact on financial management in Eastern Cape provincial departments. A qualitative research methodology was applied because the researcher is of the opinion that the research question asked is more interpretive than predictive. An interview survey was conducted in which senior management officials were selected from provincial departments and interviewed using semi-structured questions. The research study concluded, that provincial departments in the Eastern Cape have all established audit committees in line with the Public Finance Management Act (PFMA) National Treasury regulations. These committees are however ineffective. Ineffectiveness is as a result of, among other factors, lack of stability in accounting officer and chief financial officer positions. Secondly, senior management have not been made to account for the persistent negative audit outcomes in their departments. The research recommends that the political leadership of the province should ensure stability in leadership, particularly in the position of accounting officer and the chief financial officer.

- Description: Governments all over the world are faced with numerous challenges while running their countries on a daily basis. The predominant challenges which arise are those which involve statistical methodologies. Official statistics to South Africa’s infrastructure are very important and because of this it is important that an effort is made to reduce the challenges that occur during the development of official statistics. For official statistics to be developed successfully quality standards need to be built into an organisational framework and form a system of architecture (Statistics New Zealand 2009:1). Therefore, this study seeks to develop a statistical methodology that is appropriate and scientifically correct using an automated statistical system for audits in government regulatory authorities. The study makes use of Mathematica to provide guidelines on how to develop and use an automated statistical audit system. A comprehensive literature study was conducted using existing secondary sources. A quantitative research paradigm was adopted for this study, to empirically assess the demographic characteristics of tenants of Social Housing Estates and their perceptions towards the rental units they inhabit. More specifically a descriptive study was undertaken. Furthermore, a sample size was selected by means of convenience sampling for a case study on SHRA to assess the respondent’s biographical information. From this sample, a pilot study was conducted investigating the general perceptions of the respondents regarding the physical conditions and quality of their units. The technical development of an automated statistical audit system was discussed. This process involved the development and use of a questionnaire design tool, statistical analysis and reporting and how Mathematica software served as a platform for developing the system. The findings of this study provide insights on how government regulatory authorities can best utilise automated statistical audits for regulation purposes and achieved this by developing an automated statistical audit system for government regulatory authorities. It is hoped that the findings of this study will provide government regulatory authorities with practical suggestions or solutions regarding the generating of official statistics for regulatory purposes, and that the suggestions for future research will inspire future researchers to further investigate automated statistical audit systems, statistical analysis, automated questionnaire development, and government regulatory authorities individually.
