- Description: The concept of social media has grown rapidly in the last years. This can be attributed to the rate of adoption and the penetration of social media around the world. Currently, there is an estimate of over two billion people that are actively using social media. The increased usage of social media has changed the way people interact and communicate. Literature suggests that Internet-enabled social networks (relationship between or among individuals and groups) are developing faster than offline relationships. Previous studies have linked social media to the social network theories that define social relationships based on the actors, the ties that exist and the flow of resources among them. This is made possible by social networking sites and other Internet enabled services that allow friends to meet, connect and interact. Social media allow for individuals, groups or organisations to build their social network of friends and followers. It also facilitates the formation of communities with common interest. Social media facilitate the creation and exchange of content such as text messages, images, audio and video formats among individuals or communities that share a common interest or belong to the same social network. Social capital theorists suggest that the ties that exist in social interaction like on social media have the ability to create benefit for the actors in the networks. This provides the foundation to study the benefits that individuals and organisations can obtain from social media. The opportunity to target and communicate directly with the target market and potential customer qualifies social media as a valuable marketing tool and an important component of the integrated marketing communication. As a marketing communication tool, social media introduces a completely new paradigm into marketing communications. Therefore marketing professionals and academics are continuously seeking how to take advantage of social media for different industries. In the field of politics, the use of marketing concepts to engage voters and drive collective participation in political processes has become critical due to stiff competition. The use of social media for political campaigning and engagement could be beneficial, but politicians and political organisations are not taking full advantage of the concept. Previous studies show that organisations are aware of the opportunities that social media could provide for their organisations. However, they are reluctant because they are faced with the problems of lack of information on how to implement social media for business purposes. This treatise investigates the approach and critical success factors for the use of social media for political campaigning and engagement. To evaluate the conceptual framework that was suggested by this study based on the literature review and case studies, an empirical study was conducted among the members of the Democratic Alliance in the Eastern Cape. A survey was conducted among the members of the Democratic Alliance in the Eastern Cape using a questionnaire and 92 responses were received. The questionnaire measured the respondents’ social media usage, level of political engagement, perception on the use of social media for political engagement and the level of political activities on social media. Also, hypotheses were tested to examine the assumption that there might be an association between the respondents’ gender, population group and level of political activities on social media. The findings of this study indicate that a structured approach, a strong emphasis of engaging followers socially and micro-targeting are critical to effective implementation of social media for political campaigning and engagement. Other factors include the direct involvement of leadership, listening and encouragement of user generated contents. This study concludes that political organisations can use social media to establish multi-levelled social networks that provide access to their target audience and also reach potential audience through their friends. This social connectedness can then be translated into political social capital for campaign and engagement purposes.

- Description: In several countries around the world, grain commodities are traded as assets on stock exchanges. This indicate that the market and effectively the prices of the grain commodities in such countries, are controlled by several local and international economic, political and social factors that are rapidly changing. As a result, the prices of some grain commodities are volatile and trading in such commodities are prone to price-related risks. There are different trading strategies for minimising price-related risks and maximising profits. But empirical research suggests that making the right decision for effective grain commodities trading has been a difficult task for stakeholders due to high volatility of grain commodities prices. Studies have shown that this is more challenging among grain commodities farmers because of their lack of skills and the time to sift through and make sense of the datasets on the plethora of factors that influence the grain commodities market. This thesis focused on providing an answer for the main research problem that grain farmers in South Africa do not take full advantage of all the available strategies for trading their grain commodities because of the complexities associated with monitoring the large datasets that influence the grain commodities market. The main objective set by this study is to design a framework that can be followed to collect, integrate and analyse datasets that influence trading decisions of grain farmers in South Africa about grain commodities. This study takes advantage of the developments in Big Data and Data Science to achieve the set objective using the Design Science Research (DSR) methodology. The prediction of future prices of grain commodities for the different trading strategies was identified as an important factor for making better decisions when trading grain commodities and the key factors that influence the prices were identified. This was followed by a critical review of the literature to determine how the concepts of Big Data and Data Science can be leveraged for an effective grain commodities trading decision support. This resulted in a proposed framework for grain commodities trading. The proposed framework suggested an investigation of the factors that influence the prices of grain commodities as the basis for acquiring the relevant datasets. The proposed framework suggested the adoption of the Big Data approach in acquiring, preparing and integrating relevant datasets from several sources. Furthermore, it was suggested that algorithmic models for predicting grain commodities prices can be developed on top of the data layer of the proposed framework to provide real-time decision support. The proposed framework suggests the need for a carefully designed visualisation of the result and the collected data that promotes user experience. Lastly, the proposed framework included a technology consideration component to support the Big Data and Data Science approach of the framework. To demonstrate that the proposed framework addressed the main problem of this research, datasets from several sources on trading white maize in South Africa and the factors that influence market were streamed, integrated and analysed. Backpropagation Neural Network algorithm was used for modelling the prices of white maize for spot and futures trading strategies were predicted. There are other modelling techniques such as the Box-Jenkins statistical time series analysis methodology. But, Neural Networks was identified as more suitable for time series data with complex patterns and relationships. A demonstration system was setup to provide effective decision support by using near real-time data to provide a dynamic predictive analytics for the spot and December futures contract prices of white maize in South Africa. Comparative analysis of predictions made using the model from the proposed framework to actual data indicated a significant degree of accuracy. A further evaluation was carried out by asking experienced traders to make predictions for the spot and December futures contract prices of white maize. The result of the exercise indicated that the predictions from the developed model were much closer to the actual prices. This indicated that the proposed framework is technically capable and generally useful. It also shows that the proposed framework can be used to provide decision support about trading grain commodities to stakeholders with lesser skills, experience and resources. The practical contribution of this thesis is that relevant datasets from several sources can be streamed into an integrated data source in real-time, which can be used as input for a real-time learning algorithmic model for predicting grain commodities prices. This will make it possible for a predictive analytics that responds to market volatility thereby providing an effective decision support for grain commodities trading. Another practical contribution of this thesis is a proposed framework that can be followed for developing a Decision Support System for trading in grain commodities. This thesis made theoretical contributions by building on the information processing theory and the decision making theory. The theoretical contribution of this thesis consists of the identification of Big Data approach, tools and techniques for eradicating uncertainty and equivocality in grain commodities trading decision making process.

- Description: Optimum construction worker (CW) performance is required to achieve project delivery within project parameters. It is not always the case as CWs are regularly exposed to hazards, involved in accidents, their productivity is poor, they suffer from ill health, suffer from work-related musculoskeletal disorders (WMSDs) and contractors lack resources to allocate towards H&S. However, the lack or the absence of health and safety (H&S) measures, which the aforementioned depend on, has a negative impact on workers’ performance. Two descriptive surveys were conducted among professional construction project managers (CPMs) registered with the South African Council for Project and Construction Management Professions (SACPCMP) and general contractors (GCs) registered with the East Cape Master Builders Association (ECMBA). Interviews were also conducted with CPMs registered with the SACPCMP residing in the Nelson Mandela Bay metropolitan area. The salient findings include: • Accidents, which occur on construction sites, impact workers’ performance; • Inadequate H&S implementation affects both CW skills and motivation, which in turn affects their performance; • Poor constructability is relevant to H&S and CWs’ skills; • Provision and maintenance of welfare facilities are commonly inadequate and affect workers’ performance, and • Projects do not benefit from the adequate financial provision for H&S. It was concluded that exposure to hazards, poor site conditions, inadequate provision of welfare facilities, WMSDs, and insufficient financial provision for H&S affect workers’ performance by either incapacitating or demotivating them. Recommendations include : CPMs should make better use of their influence on clients; they should improve communication channels between project stakeholders; legislators need to raise awareness regarding H&S and worker welfare, and training and education institutions need to empower workers and professionals with H&S knowledge.

- Description: The construction industry (CI) is well known to be one of the most dangerous industries in South Africa (SA) due to the complex nature of construction activities, advancement in technologies and an aging workforce, emphasising the need for training. Over the past two decades, the industry has come under the spotlight regarding Health and Safety (H&S). The Occupational Health and Safety (OH&S) Act 85 of 1993 and Construction Regulations (CR) 2014 as amended are the statutes that govern the H&S in the construction workplace. These statutes aim to provide minimum guidelines by which all operating in the industry should abide by in order to ensure the safety of all persons at work. A fundamental aspect of the OH&S Act and CR is for construction employers to assess occupational hazards and conduct risk assessments with remedies to mitigate or prevent such risks. Furthermore, employers are compelled by law to ensure that employees are made aware of the risks at the induction stage, in addition to preventative measures associated with their work activities. Therefore, training forms the structure by which H&S in the workplace can be improved. Training in itself is not enough if it is not based on the employees’ needs as assessed. Training needs to be relevant and effective if it is to have a significant effect in the prevention and possible reduction in the number of occupational injuries and fatalities in the CI. A question that led to the basis of this research was why there were such poor H&S practices in the CI when the statutes clearly require the importance of training. This research is aimed at establishing the effectiveness of service providers relative to construction. Service providers offer services such as training, auditing, SHEQ management, and other H&S related matters. Of fundamental importance is that training has a direct or indirect influence on the health and safety (H&S) of employees in the workplace. Thus, this research aims to determine the effectiveness of training offered by these service providers relative to construction. The researcher utilised the quantitative data collection method to collect primary data from a sample surveyed through a questionnaire, whilst collecting secondary data from books, the Internet, professional journals, and articles. The sampled population consisted of service providers, health and safety practitioners, construction managers, supervisors, and workers, all from the Nelson Mandela Bay Municipal Area. The data was analysed quantitatively using the Statistical Package for Social Sciences (SPSS), ANOVA and the one-sample t-test. The literature reviewed and findings of this quantitative research amongst construction personal such as top, senior, middle management (TSMM), and general workers and labourers (GWL) in the Nelson Mandela Bay Municipal area formed the basis of this study. The study reveals that training offered by service providers was indirectly unrelated to construction. Furthermore, the study also showed that management concurred that there was a strong belief that language did not influence their ability to understand the contents of the training, which is mainly provided in English. The group believed that training from service providers were at the correct level. Alternatively, GWL were of the belief that language influenced their ability to understand the training received. The study also indicated that procurement of these service providers were not based on their skills, knowledge and background in construction. This may be attributed to the fact that management are more advanced in terms of education than GWL. Lastly, the study revealed that a significant number of Safety, Health and Environment (SHE) officers are in the process of registering with the South African Council for the Project and Construction Management Professions (SACPCMP), the professional body responsible for the registration of Construction Health and Safety (CH&S) professions. This study will conclude with findings, conclusions, and recommendations that will be valuable to construction companies relative to the services of service providers.

- Description: Effective leadership is and will remain the cornerstone of business success. It is leadership that differentiates world class from mediocre performance. The objective of this study is to investigate how positive leadership brand can be developed in order to leverage human capital and enhance the competitive position of organisations. To achieve this objective a comprehensive literature study was performed to determine the extent of existing knowledge on branding, leadership and leadership branding. The study included an investigation into the attributes of effective leaders, leadership development activities, leadership styles and a formula for effective leadership was presented. Managers from selected organisations were requested to complete questionnaires in order to determine the views of South African managers on leadership branding. The questionnaire was developed in accordance with the findings from the literature research. The answers of the respondents were analysed and compared to the literature study. The information obtained from the literature study and from the respondents resulted in various recommendations and conclusions. In general, support was found for investing resources into developing leadership brand as respondents indicated that positive leadership brand could result in a source of competitive advantage. The major obstacles in developing positive leadership brands are: absence of a clear message of what makes an effective leader, lack of feedback that leaders receive on the behaviours they display and no (or an unknown) link between leadership behaviours and rewards.

- Description: The primary aim of this study was to investigate the seasonal changes that occur in the anthropometric, physical and motor characteristics of elite junior soccer players over the course of a training year. The participants targeted were elite soccer players from the NMMU-FCK Soccer School of Excellence and a total of 18 players between the ages of 15 to 18 years were recruited to comprise the sample for the study. The participants in the sample were assessed on four separate occasions. Each testing period was separated by a three month interval with the first testing period taking place in June 2005, at the start of their pre-season period, and the last testing session taking place in March of the following year, at the end of their playing season. In order to determine which specific characteristics of soccer were to be tested, the relevant literature was reviewed to establish the requirements, attributes and indicators of success in elite soccer. Therefore the test battery used was compiled in an attempt to address each of the identified physical attributes that contributes to successful soccer play. The battery included the following tests: weight, height and percentage body fat to represent the anthropometric characteristics. The physical characteristics were assessed by testing flexibility, anaerobic speed endurance, aerobic endurance, and muscular strength tests (1 RM bench and leg press, grip strength, and isokinetic knee strength). The motor assessments comprised of tests for speed (10-m, 20-m, and 40-m), explosive leg power (vertical jump), agility, and soccer-specific tests (dribbling and shooting at goal). In addition maturity status during the study was assessed using grip strength and height scores. All of the participants within the study sample were assessed on each day of the testing period, in alphabetical order, and this order was maintained during each testing period. Each of the four testing sessions lasted three days. On entering the Nelson Mandela Metropolitan University-Biokinetics and Sport Science Centre (NMMU-BSSC) laboratory on day 1, the participants completed the test battery in the following order: anthropometric measurements (weight, height, skinfolds), flexibility test (sit and reach), leg power test (vertical jump), muscular strength tests (1RM bench press, 1RM leg press, grip strength), and an aerobic endurance test (Multi-Stage Shuttle Run). The tests conducted on day 2 of the test battery were conducted as field tests at the NMMU-FCK soccer playing fields and the participants completed the tests in the same alphabetical order as day 1. The testing battery was conducted in the following order: speed tests (10m, 20m, and 40m sprinting), agility test (Illinois agility run), soccer-specific tests (dribbling and accuracy tests), speed endurance test (Yo-Yo intermittent recovery test). Testing on day 3 consisted of Isokinetic dynamometry strength testing and was conducted at the NMMU-BSSC. Each participant completed the testing protocol according to the same alphabetical order as was used on days 1 and 2. In order to achieve the aim of the study, the following objectives were set: to determine the anthropometric, physical and motor characteristics of the participants at the pre-season, start of season, mid-season and end of season stages of the training year and to identify the peak scores achieved for each variable tested; to compare the variables tested at each of the four testing sessions to determine the progression of each variable tested and to identify at which testing session peak performance related fitness was achieved; to compare the results obtained with relevant data from other research literature; and to monitor the maturation status of the participants. Based on the results achieved it can be concluded that the participants achieved peak physical fitness at the mid-season period (testing session 3). It would appear that the attainment of these results was determined by the participants being exposed to both a pre-season and an in-season training period. It seems that both the completion of the specific types of training that occurred during these two periods, as well as the competitive matches played, elevated the participants physical fitness to the levels required for success at the elite level.

- Description: Physical inactivity and resultant chronic diseases of lifestyle (CDLs) are becoming a global epidemic as secular modernization and the sedentary lifestyles it brings with it become universal. The importance of physical activity (PA) in reducing morbidity and mortality from CDLs and related conditions has been well established. Since it is generally significant that the onset of many CDLs lies in childhood through to adolescence, preventative strategies should start as early in life as possible. Currently, university students are failing to engage in the levels of PA recommended for better health outcomes over the short and long term. To make matters worse, there is increasing evidence of a decrease in PA during the transitional phase from adolescence to adulthood. This study aimed to determine the physical activity (PA) levels, sedentary behaviour and health-related fitness (HRF) characteristics of female university students. In addition, the participants‘ perceived barriers to PA were investigated. The study was exploratory-descriptive and employed a quantitative research design. Five hundred and thirty-one full-time female students, between the ages of 18 and 46, studying at Nelson Mandela Metropolitan University‘s (NMMU) South, North, Second Avenue and Missionvale campuses participated in the study. The participants (n=531) completed an online survey which determined their PA levels, sedentary behaviours and perceived barriers to PA participation. A health-related fitness (HRF) assessment was also administered to 68 participants who completed the online survey. Their height, weight, and waist and hip circumferences were measured, as well as their cardiovascular fitness (CF). The majority (88 percent) of the participants reported low and minimal levels of PA, and 44 percent were either overweight or obese. The participants had a low-risk waist-to-hip ratio (WHR) (M=0.70). The majority of the population (94 percent) had poor cardiovascular fitness (CF). A high prevalence of sitting time was recorded among the participants: on average 855 minutes (14 hours) on a usual weekday and 720 minutes (12 hours) on a usual weekend day. Students reported the greatest length of sitting time at work/attending lectures/studying. Cross tabulations and Chi2 tests indicated no significant relationships among PA and HRF (BMI, WHR and CF) and sedentary behaviour and HRF. The ANOVA and t-test results for PA, sedentary behaviour and HRF related to various demographic variables, found small (0.19 < d < 0.50) and medium (0.49 < d < 0.80) significant differences by race (d=0.43; d=0.52), home language (d=0.41; d=0.44) and living arrangement (d=0.38; d=0.28). No significant relationship was found to exist between age, year of study and faculty of registration and sedentary behaviour or HRF. The participants listed: Not enough time; too expensive to exercise; and, no friends who can exercise with me as the most important barriers to participation in PA. Academic obligations (3.08 mean) was found to be the most important barrier to PA.

- Description: Cancer is a disease that imposes a heavy burden on public health and poses a challenge to science. The World Health Organization estimates that 80 percent of people in developing countries of the world rely on traditional medicine for their primary health needs, and about 85 percent of traditional medicine involves the use of plant extracts. This is particularly true in Africa where a large percentage of the population depends upon medicinal plants for health care. Therefore, detailed screening and evaluation of bioactive substances for chemotherapeutic purposes of African plants are urgently warranted. Furthermore, this will serve to validate the efficacy and safety of African traditional medicine. The current study investigated the in vitro cytotoxic effects of 17 ethanolic extracts of the following 16 plants used in traditional anticancer medicine in Nigeria: Sapium ellipticum leaves, Sapium ellipticum stembark, Combretum paniculatum, Celosia trigyna, Pupalia lappacea, Justica extensa, Hedranthera barteri leaves, Alternanthera sessilis, Ethulia conyzoides leaves, Lannea nigritana stembark, Combretum zenkeri root, Combretum molle leaves, Adenanthera parvoniana, Lannea acida, Cyathula achyranthoides, Drymaria cordata, Cyathula prostrata, against HeLa cancer cells. Five of the most promising extracts (Sapium ellipticum leaves, Combretum paniculatum, Celosia trigyna, Drymaria cordata, Cyathula prostrata) were selected for further screening against HT29 and MCF-7 cancer cells. Of the five, the first two were investigated further based on their activities in the screening phase. The S. ellipticum leaf extract yielded IC50 values of 88.60 ± 0.03 and 93.03 ± 0.03 μg/ml against HeLa and MCF-7, respectively. The toxicity was also evaluated on normal cells and an IC50 of 77.66 μg/ml was obtained for peripheral blood mononuclear cells (PBMCs). The IC50 values for proliferating and confluent Chang liver cells were both >125 μg/ml. These results suggest that the extract may be selective for specific cell types. Bio-assay guided fractionation of the S. ellipticum ethanolic extract yielded two active fractions; chloroform and ethyl acetate. Two compounds isolated from the chloroform extract were screened against the three cancer cell lines and found to be inactive. Three compounds were isolated from the ethyl acetate fraction and revealed IC50 values < 62.5 and < 31 μg/ml against MCF-7. Unfortunately these two compounds soon lost activity before any further work could be done on them and work was continued with the crude extract.

- Description: The construction sector serves as the engine of growth to the South Africa economy because of its catalytic role in the growth and development of the country. This study focuses mainly on the influence of the macro-economic environment on the contribution of the private sector to construction in the South Africa economy from 1984 to 2011. Government construction work is considered to be an injection into the economy; in this regard, state construction is regarded as public investment in the economy; and therefore, it is anti-cyclic (Keynes, 1936). The aim of this study has been to develop an econometric model for predicting the influence of the macroeconomic environment on the contribution of the private sector to the construction sector in the South Africa economy. The research design adopted in this study was an “ex-post facto” type, otherwise known as a causal-comparative design. The data were extracted from the published sources of the South African National Statistics, namely SARB, Stats SA and Quantec SA. The estimation technique used in this study was the ARDL model using quarterly data from 1984 to 2011. This is because in the construction sector, the influence of the independent variables is always felt over time – rather than all at once. The results of this study show that there is a long run causal relationship between inflation rate, interest rate, real exchange rate, GDP and gdp in the construction sector. The descriptive statistical analysis shows that there is a negative relationship between variables inflation rate and interest rate and the private sector spending in construction. However, economic growth as well as growth in the construction sector has a positive relationship with the private sector spending in construction. Likewise, the real exchange rate and labour productivity in construction have a negative relationship with the private sector’s spending in construction and they are statistically insignificant. The variance decomposition analysis show that the private sector spending in construction explains about 75 per cent of it variations, followed by inflation rate that explains 21 per cent on the average; while the remaining variations, comprising about 4 per cent, were shared among the other independent variables, such as GDP, GDP in construction, the interest rate and the real exchange rate. It was discovered that only the inflation rate does Granger-cause the private sector spending in construction. From the finding it can be concluded that inflation rate is a significant explanatory variable in explaining the variation in the dependent variable during period under review. Policy recommendations are as follows: firstly, the monetary authorities in South Africa should embark on sound policies that would bring about low prices of the construction materials. This would ensure growth and development in the construction sector; secondly, a stimulating development plan that would encourage private sector investment in properties and infrastructural development must be instituted; thirdly, an alternative policy to the present inflation targeting is recommended that would bring about low inflation, high growth, low unemployment and stable exchange rate; fourthly, the present policy on interest rate must be reviewed to allow for more participation in construction projects by the private sectors of the economy; fifthly, due to the fact that fluctuation in the crude oil prices in the international market is one of the major factors causing high inflation rate in South Africa, government must source local alternative products that would bring down prices of construction materials.

- Description: It has been generally accepted within the developed and developing countries of the world that SMES contributes significantly to employment creation as the world population increases and that it also contributes to the economic growth of the areas they are situated in. Finance is the blood (life) of any business, for a business to be successful it needs steady successful access to funds and post financial support which leads to actualization of ideas, leads to investment and expansion, improves access to market amongst others. This is why the impact of development finance can never be over emphasized. The aims of the study are: To understand the extent to which small and medium businesses are supported through the availability of financial assistance in Matjabeng Municipality. To establish the survival rates of businesses that has been funded and or supported and whether they are or not sustainable. In achieving the aims and objectives of the research, the researcher looked at development funds both from the supply side and the demand side. The supply side which involved semi structured interviews with consultants of government parastatals (the FDC and DETEA) who are involved in financing Small Medium Enterprises in Matjhabeng municipality. The demand side involved administering of questionnaires to Entrepreneurs in the municipality who are registered with the Local Economic Department (LED), which led to the acceptance of the hypothesis of the research that development finance actually helps in the growth of small medium enterprises but in conjunction with post financial support such as bookkeeping, accounting, monitoring and evaluation. The researcher also discovered some findings amongst others which includes: The most effective ways entrepreneurs heard about funding in the municipality are through the media and word of mouth. Most of the entrepreneurs that received some type of funding are startups. More entrepreneurs that had access to funds also got some post financial business support. Financial assistance to entrepreneurs yielded improvements after respondents received financial assistance, the range of goods offered was improved and more jobs were created, entrepreneurs were able to obtain better business premises either by renting or buying and entrepreneurs had access to better equipment. Some of the recommendations of this study includes; The municipal government should help small and medium enterprises in the municipality by linking them to new markets. Effective monitoring and evaluation systems should be put in place by development funders and non-financial support services. Entrepreneurial skills development should be provided by the public and private agencies by organizing workshops for aspiring entrepreneurs in order to expose them to business opportunities that are sustainable and viable.

- Description: To thrive, developing countries depend on high levels of protection being given to key industries such as manufacturing; specifically the automotive and textile industries. South Africa, as a developing country and especially under the emergence of globalisation, has followed suit in terms of developing policies and structures to protect certain critical industries. During an era (1980 to 1989) of high political instability, South Africa experienced isolation from the rest of the world, which resulted in declines in industrial revenues as well as the country’s automotive industry undergoing a stage of perilous stagnation. It was through a protection regime that the automotive industry realised growth, a regime which started slowly in 1989 and accelerated in 1995 with the introduction of the Motor Industry Development Programme (MIDP) (Black, 2001). Through this regime the South African government sought to integrate the South African automotive industry into the global market by improving the competitiveness of this industry (The DTI, 2010). This led to the automotive industry becoming one of the most successful export sectors in South African manufacturing and a large net consumer of foreign currency, totalling R20 billion and R10 billion in imports and exports respectively by 1998 (Damoense and Simon, 2004). Reviews of the government legislation called the MIDP were held in year 1999 and 2002 and in 2008, a successor to the MIDP was named, the Automotive Production Development Programme (APDP) and is set to commence in year 2013 until 2020. Unlike its predecessor, the APDP policy promises to bring greater and more inclusive benefits to the automotive industry as a whole, provided organisations have prepared well to receive it. This study investigated whether organisations have prepared for the upcoming 2013 - 2020 APDP, with specific reference to capital investment in equipment. It determined whether automotive organisations have spent and are going to spend resources in securing equipment and technology in preparation for the introduction of the APDP.

- Description: This research project aims to assess development projects in the energy sector with its focus on the shale gas exploration in the Karoo. The assessment is based on a critical analysis of the concepts and principles of sustainability, complexity and the National Environmental Management Act, using a critical hermeneutics methodology to develop an assessment criterion. Critical hermeneutics is the science and art of interpreting texts, challenging the status quo, its influences and assumptions. Hermeneutics is the reaction to enlightenment fundamentalism, which is an over-reliance on rationality and the scientific method as a primary means of obtaining truth. Hence this research has adopted a triangulation of ideas and concepts derived from sustainability and complexity to find the truth about the sustainability of development projects (Cilliers, 1998; Deleuze & Guattari, 1994; Byrne, 1998). The Central Karoo is situated in the North Eastern part of the Western Province. It is characterised by dry, arid conditions with highly environmentally sensitive land. Central Karoo has the smallest concentration of people in the Western Cape (Van Vuuren, 2008). This research project offers an assessment that will help governments determine the feasibility of energy sector projects since it discusses the impact of exploration for shale gas in the Karoo and explains the process, recommendations and the environmental legislature required for any project to take place in South Africa. Further, it highlights the environmental damage caused by the shale gas exploration as well as the positive economic impact that it could have on the country. For this research, hermeneutics has offered a framework rather than a system; it is a research philosophy that places human experience at the forefront as it honours a variety of interpretations.

- Description: Die Eden- en Overbergdistrik in die Suid-Kaap vorm die mees suidelike substreke van die winterreëngebied. Dit is geleë tussen 33° 45‟ en 34° 50‟ suiderbreedte en tussen 19° 0‟ en 23° 45‟ oosterlengte. Die westelike grens van die substreek word gevorm deur die Villiersdorp-Botrivier-gebied. Aan die noordekant word die substreek begrens deur die Sonderend-, Lange- en Outeniquabergreekse. Die oostelike grens word gevorm deur die Bloukransrivier. Die Indiese Oseaankuslyn vanaf Nature‟s Valley in die ooste tot by Kleinmond in die weste vorm die suidelike grens. In die Suidkusstreek word 54.5% van die Wes-Kaapse melkproduksie en 24% van Suid-Afrika se melkproduksie deur 1900 melkprodusente geproduseer (Dowrey 2005). Ses en dertig persent van die bruto jaarlikse veeproduk is afkomstig vanaf suiwelprodukte wat hoofsaaklik vanaf aangeplante weiding geproduseer word. Aangeplante weiding beslaan 37.7% van die totale oppervlakte van die vee- en saaigebiede van die Suidkusstreek (Botha 2003). Weens beperkte, skaars besproeiingswater in groot dele van die Suid-Kaap, word heelwat weiding slegs aanvullend besproei (Protopapas 2004). Voervloeiprogramme vir melkproduksie onder aanvullende besproeiing bestaan hoofsaaklik uit kikoejoe (Pennisetum clandestinum) en lusern (Medicago sativa) (Botha 2003). Die droëmateriaalproduksie en weikapasiteit van lusern volg, soos kikoejoe, „n baie sterk seisoenale tendens met „n piek in die somer / herfs en „n laagtepunt in die winter (Durand 1993; Botha 1998; Botha 2003). Voervloeiprogramme met lusern of kikoejoe as hoofkomponente het gewoonlik voertekorte gedurende die winter tot gevolg. Hoofsaaklik om dié rede het boere uit die lusernproduserende gebiede van Heidelberg, Riversdal, Herbertsdale en Mosselbaai, deur hul onderskeie boereverenigings, „n versoek aan Outeniqua Navorsingsplaas gerig om ondersoek in te stel na moontlike oorsaaipraktyke wat die droëmateriaalproduksie van lusernstelsels gedurende die winter kan verhoog. Kikoejoeweiding word reeds die afgelope aantal jare suksesvol met Westerworldsraaigrasse oorgesaai vir beter herfs-, winter- en lenteproduksie. Anders as by kikoejoeweidings bestaan daar huidiglik geen beproefde oorsaaipraktyke wat die produksiepotensiaal van lusern in die winter en vroeë lente kan verhoog nie (Anoniem 2002).

- Description: There is a global increase in research on the benefits of animals and the value of incorporating them into interventional practices. This is referred to as animal-assisted interventions. Due to the novelty of this type of intervention and the accompanying complexity of variables, a need exists to explore the various aspects within these interventions. Looking specifically at animal-assisted interventions within the mental health field, this study focuses on the psycho-therapeutic value of companion animals, such as dogs and cats. The primary aim of this study was to identify the mechanisms through which an animal-assisted intervention exerts its influence. A secondary aim was to indentify salient methodological aspects within the included studies. A systematic review of existing literature was undertaken to explore these factors. Each study was appraised against specific inclusion and exclusion criteria and themes were extracted. The data was synthesised, integrated and discussed in relation to previously conducted studies in relevant fields. Six themes emerged from the systematic review. These included enhanced comfort, the living nature of animals, physical contact, adjunctive nature, an affinity for animals, as well as methodological considerations. Based on these emergent themes conclusions were drawn as to the psycho-therapeutic influences of companion animals. This may serve as informative knowledge regarding animal-assisted interventions for practitioners seeking additional methods to reach treatment goals. Information is also provided for researchers interested in the field, particularly methodological considerations, before embarking on a study of animal-assisted intervention efficacy.

- Description: The simulation of vehicle engine cooling validation in a Climatic chamber will benefit all vehicle manufacturers that are responsible for the design or the localization of parts used in a vehicle's engine cooling system. The ability to test the vehicle in-house allows testing at any time of the year; it provides repeatable and comparative data, and accelerates component level approval, which in itself reduces program timing and cost. For this dissertation road level testing was conducted in Upington using a TD1200 Superflow towing dynamometer, while the in-house testing was performed on a ROTOTEST chassis dynamometer in a Climatic chamber. All tests were conducted according to GENERAL MOTORS SOUTH AFRICA global testing standards. Statistical analyses of the test data were used to determine the relationship between parameters measured and results obtained. The major contributors to the simulation process was identified and implemented to improve measurement quality and test results. The result was an accurate simulation between road and chamber testing, hence the possibility of moving away from road testing and conduct simulated chamber testing. The presented dissertation is useful for the understanding of basic vehicle cooling testing and the methodology of simulated testing in an environmentally controlled chamber.

- Description: Information literacy is universally considered one of effective means through which one’s information skills are developed, more especially at higher education Institutions. It has been part of the WSU library’s tradition to promote and offer units of Information Literacy instruction to all students at WSU, although it was initially on ad-hoc bases until 2010 when the Faculty of Education introduced it as a module or a program as a credit-bearing subject to all first year level Bachelor of Education students. The study is intended to understand the perceptions of students that are currently enrolled in Bachelor of Education Degree level one regarding the Information Literacy Program at Walter Sisulu University. The Information Literacy Program is offered in two campuses of WSU, that is Mthatha and Butterworth campuses. This study was conducted using first year level B. Ed students in Butterworth campus only. This may be regarded as a limitation of the study. The study is largely informed by a literature review of scholarly journal articles, books, internet sources and academic libraries in South Africa. The study applied quantitative method using semi-structured questionnaires as the main data gathering instrument. The sample was drawn from 80 first year B Ed students. A total of 80 questionnaires were distributed and 65 were received back. In the study the significant changes in the higher education in the post-apartheid South Africa are discussed. The historical evolution of information literacy as a course in South Africa and internationally is also discussed. The study reveals that information literacy has contributed positively to students’ study approaches. It has helped the students to learn how to apply computing and internet skills to improve on their studies. More importantly, the study reveals that information literacy has helped the students to learn different ways to search for and use information for the purpose of working on their assignments and enhancing their knowledge generally. Furthermore, the study reveals that it has helped the students to know how to tailor their search for information using specific databases such as OPAC, PROQUEST, EBSCOHOST, and SABINET etc.

- Description: This study seeks to investigate the underlying ideologies and practices behind the perception that women who are in command positions are unable to command and control, especially those who are in the operational environment. The study was executed in the Eastern Cape Province (Eastern Cape), in Buffalo City Metropolitan Municipality (BCM). The research participants (respondents) were constituted by 33 police officers from diverse police stations within the BCM. The participants were divided according to gender, i.e. 24 females and 9 males. With regards to objectives of the study, the aim was to investigate the following issues: i) to understand factors that make women not to be accepted in their positions as SAPS' operational commanders, by their male subordinateslcolleagues and community members. ii) To understand factors that make women not to be accepted in their positions as SAPS' operational commanders, by their male subordinates/colleagues and community members, and iii) to explore strategies to utilize in making SAPS' women operational commanders, survive while managing their day-te-day respective units/components effectively and efficiently. Regarding research design, this study mainly used a qualitative research method combined with a bit of a quantitative approach. And then the data collection method involved making use of semi structured interviews to all the respondents. The results of this study show that there is still a huge difference in the number of women who are commanders compared to their male counterparts, especially in those environments that were previously regarded as male dominated. Further, despite the necessary training being provided by the SAPS to women officers, the necessary support in particular from management is still a challenge. Lastly, the argument of this study is that there is still not a fair representation of women in command positions within the SAPS, especially, in the previously male dominated environments.

- Description: This treatise is founded in a belief that urban ecosystems should not be separate from natural ones and seeks to find ways in which existing urban systems can be reintegrated. This reintegration will be two-fold, providing a remedy for ecologically destructive urban systems as well as providing an opportunity to develop a holistic and sustainable alternative to current practices that generate waste and pollution. The treatise will focus on the management of polluted storm water, specifically along the Walmer catchment area which flows east into Airport Valley and Shark River Valley, and ways in which horticulture building systems can be utilised to achieve remedial action naturally, producing vast amounts of nutritious food for the surrounding community in the process. Impetus for this topic grew out of a concern that the author has for the current state of sustainable practices within South Africa, specifically regarding the relationship between water and agriculture (food). 60 – 70% of South Africa’s water demand is agricultural, with poor water management infrastructure and the current drought severely affecting the agricultural output (food supply) of the country. The increased demand puts immense pressure on South African farmers who have dwindling arable land and less water with which to cultivate crops. South Africa’s population is two thirds urbanised, meaning that most of the population lives in urban centres around the country. This treatise proposes that water-wise urban agricultural systems could be utilised to further cement food and water security in an urban setting by supplementing the food supply chain with local, city-grown produce. The research conducted will generate an architectural and urban intervention that marries the natural with the built environment in a strategically and intentionally designed relationship that exploits synergies between these two environments.

- Description: There has been a long history of attempts to promote subsistence rural aquaculture within South Africa. Many of these attempts have failed due to inadequate support from government and support agencies. There has been a recent revived interest in promoting rural aquaculture development. Presented in this project are six scenarios demonstrating the potential application of thermal modelling techniques to improving subsistence rural aquaculture. These scenarios were based on a model validated against a real life system, and run with environmental data for the year 2005. Bovine manure, grass thatch, cereal straw and Typha spp. water reeds were tested for thermal performance. These results were then applied to the scenarios. The open and kraal enclosed pond scenarios yielded the widest deviation in temperatures throughout the year, with an average temperature of 3.8oC and 6.0oC above ambient and a temperature range of 10.6oC and 12.4oC for the year respectively. Eliminating solar radiation and reducing wind speed resulted in an average difference of 1.5oC below ambient and a temperature range of 7.5oC for the year. When completely enclosed in a well-sealed traditional Xhosa style hut, the pond had an average difference of 5.6oC below outside ambient temperature, with a range of 7.8oC for the year. A passive solar heating scenario added to the sealed hut scenario, which when run continuously maintained an average difference of 34.7oC above outside ambient temperatures, with a range of 56oC for the year. When a hypothetical 25oC temperature control was included in the model, the system maintained an average of 7.1oC above ambient outside temperatures, with a temperature range of 0.8oC throughout the year. The wider range of temperatures made available through the use of thermal modelling approaches provides a more diverse range of species available for subsistence rural aquaculture at any site, significantly improving its potential.

- Description: In today’s dynamic market, it is crucial that logistics systems understand their activities and processes in an efficient way. Lean, in essence, is a method to assist companies in rendering efficient services to customers (Andrejic, 2013, p. 84). The Lean approach for waste elimination can be applied to many different types of operations whether in manufacturing or service industries. The identification of warehousing wastes is sometimes considered difficult in its identification within processes (Villareal, Garza, Rosas & Garcia, 2012, p. 278). The purpose of this case study is to contribute to finding a solution for the decreasing operational efficiency in the operation under study. The researcher found that this paper filled an important research gap in terms of offering management of the selected logistics institution a better understanding of the different waste types in each process. Operational areas such as receiving, unboxing, put-away, picking and issuing were examined as possible reasons for concern about service orientated wastes. The research was conducted through observations and thereafter a questionnaire was distributed amongst a sample of 40 employees within a specific logistics institution. The study discussed certain key factors in Lean, specifically focusing on the types of waste in a service environment.
