- Description: Chronic diseases of lifestyle (CDLs) are non-infectious medical conditions, such as diabetes, cardiovascular disease and cancer. These conditions are the second leading cause of death and disease in Africa. Failure to modify primary risk factors, such as an unhealthy diet, lack of physical activity and tobacco use, can give rise to intermediate risk factors such as hypertension and obesity, which predispose individuals to CDLs. The aim of the research was to investigate the use of smart devices to facilitate the self-management of health and health behaviours. The Health Action Process Approach (HAPA) model of health behaviour change was adopted, which focuses on the correction of modifiable risk factors. Two smart devices were selected, namely the Fitbit Charge 2 and Fitbit Aria, which monitor specific physiological information. The Fitbit Charge 2 can determine health activity, and the Fitbit Aria can determine the weight, body mass index (BMI) and body fat percentage of an individual. A field study was conducted with 22 participants (11 males and 11 females) to evaluate and determine the effectiveness of the smart devices. The participants were sampled from Nelson Mandela University staff and were aged between 30 and 60 years of age. The field study was conducted over two weeks in two one-week long phases. The first phase was used to obtain subjective data (using a lifestyle questionnaire), and objective health data (collected by the smart devices) from the participants. The purpose of the first phase was to form intentions. The second phase was the goal setting phase, where each participant was assisted in setting manageable personal goals. The results show that the smart devices used in the research could be used to provide motivation and monitor health data to support self-management of CDLs. The use of these smart devices was included in an updated HAPA model.

- Description: Purpose: The first phase of this study aimed to investigate the health and fitness status of young adult females in the local community. The second phase of this study investigated the impact of an eight week progressive Pilates intervention on selected health and fitness parameters in this cohort. Methods: Healthy young adult females aged 18-26 years (n=96), from the local community, partook in once-off tests including anthropometric measures (stature, body mass, Body Mass Index and waist circumference) as well as fitness parameters including balance, flexibility, muscular strength and endurance, and lastly lumbo-pelvic stability. Health measures investigated included blood pressure and spirometry. Where possible, results were compared to those of similar populations from national surveys or published normative data. Sedentary volunteers from this cohort were then randomised into a Pilates Exercise (PEx, n=12) or an inactive Control (Con, n=11) group, with their results from Phase 1 serving as baseline measures. Pilates classes were held twice weekly (60 minutes per session). All the measures from phase 1 were repeated at weeks 4 and 8. An additional intervention test included Transversus abdominis recruitment. Participants maintained habitual dietary intake and energy expenditure throughout. Nine PEx group and eight Con group participants completed the intervention. Results: The current sample (phase 1) was found to be healthier than comparative populations from national surveys, and significant differences (p<0.05) were found for all comparisons except Forced Expiratory Volume (FEV1), (p=0.64). Physical activity levels (230 min.week-1) exceeded that of the recommend weekly threshold (150 min.week-1). BMI, waist circumference, blood pressure and spirometry measures were all found to be within suggested healthy normal ranges. Pilates significantly improved lumbo-pelvic stability in the PEx group at weeks 4 (p<0.005) and 8 (p<0.002). Similarly, abdominal (p=0.00, d=1.1), upper limb (p=0.037, d=0.9) and lower limb endurance (p=0.02, d=1.0, between group d=0.73 for PEx) also improved with no changes in the Con group. PEx energy expenditure significantly increased from baseline to weeks 4 (p=0.007, d=10.7) and 8 (p=0.027, d=0.64), however body mass was maintained throughout. Conversely, Minute Ventilation decreased in the PEx cohort (p=0.010, d=0.95) from weeks 4 to 8. The Con group showed significant increases in body mass (p=0.018), leg strength (within-group Cohen’s d=-1.08 between weeks 0-8; d=-2 between weeks 4-8) and dynamic balance (p=0.01, d=-0.5). While no within-group changes were observed, Protein intake was significantly greater (p=0.036, d>0.8 at baseline and week 8) in the PEx group throughout the intervention. Medium between-group effect sizes (d>0.5) were noted for PEx BMI and waist circumference measures at all time points. Further, although not significant, the large within-group effect size (d=-0.84) between baseline and week 8 for PEx systolic blood pressure, suggested the 9 mm Hg was meaningful. The same time period also indicated a large within-group effect size (d=-0.8) for PEx dynamic balance, and a medium Cohen’s d for (d=0.57) PEx static balance. Conclusion: The local population of young adult females was found to be significantly healthier than those of comparable national samples. Further, Pilates participation significantly improved lumbo-pelvic stability and muscular endurance with meaningful changes in systolic blood pressure, and balance in previously sedentary young, adult females. Body mass was also maintained.

- Description: There is great concern about substance use among high school learners locally and globally. Adolescents are considered to be a high-risk population as their developmental stage generally renders them more susceptible to peer influence. It is for this reason that school based peer-led substance use prevention programs are considered to be a logical intervention aimed at reducing the onset of adolescent substance use. This study was motivated by inadequate information available regarding learners‟ experiences with school-based substance use prevention programmes and their effectiveness. This was a qualitative study that was exploratory, descriptive and contextual in nature. A non-probability, purposive sampling technique was administered to grade 8-11 learners aged 13-16 who have been recipients of school-based, peer-led substance use prevention programmes for a minimum of two consecutive years. The collection of data entailed individual interviews using semi-structured interview guide and focus group discussions. Data was collected until point of saturation was achieved, and analysed using Tesch‟s thematic data analysis. The credibility of the research process and the findings was enhanced by employing a variety of data verification strategies. It is anticipated that this research contributes to a better understanding of how school-based, peer-led substance use prevention programmes can be tailored to the needs of high school learners.

- Description: A significant interest in school educational leadership has developed over the past two decades, whereby effective leadership is required in a continually changing educational environment. This study is a historical analysis of leadership styles of headmasters at Kingswood College in Grahamstown (Eastern Cape, South Africa) from 1993 to 2017. The aim is to identify leadership style(s) of headmasters using the Full Range Leadership (FRL) model as a guiding framework; to describe and interpret these style(s) in relation to the headmaster’s tenure; and to compare the headmasters’ leadership styles, noting key similarities and differences. The research method consists of interviews and a historical archival analysis. The researcher’s expectation is that headmasters will elicit a transformational leadership approach. Key findings were somewhat consistent with this hypothesis, as headmasters exhibit a general trend towards transformational leadership; although each headmaster identifies with a unique facet of transformational leadership, together with relevant supporting leadership style(s) that emerged from the data. Upon comparing headmasters, their primary leadership styles were as follows: Wilkinson identified with transactional, transformational and servant leadership; Hawke showed evidence of a transformational servant leader; Arguile elicited transformational and principle-based leadership; and Trafford depicted transformational and participative leadership. The researcher found that multiple factors in an ever-changing educational environment promoted the need for transformational leadership. The relationship between business management and educational leadership emerges as a key reflection, thus further research is required in this regard.

- Description: The study reviews the household’s perceptions and determinants of sustainable products harvesting. Communal rangelands are vast natural landscapes in the form of grasslands, shrubs, woodlands, wetlands and deserts with multiple functions to the rural households. Most rural communities share boundaries and interact with rangelands for multiple socioeconomic and environmental reasons. Since most of these interactions are external to the price mechanism, the actual contribution of rangelands to communities has largely been missed. In an effort to appraise and explore the communal rangeland contribution to households, a study from Dyamala community in the Raymond Mhlaba Local Municipality under Amathole District in Eastern Cape was conducted using cross-sectional data. Descriptive results revealed that the majority of the respondents (71 percent) from the study area positively perceived communal rangelands as safety nets. however, there also emerged a fair share of challenges namely, (bad spirit, host predators, compete with arable land) leading to negative perceptions towards communal rangelands. It was also evident that, the majority of respondents from the study area use communal rangelands for fuel wood, construction poles, traditional medicine, with minor harvests of wild food (flora and fauna) and thatch grass. The results of the study also revealed that, rural people depend more on social grants for their income followed by incomes from remittances, agricultural activities and communal rangelands. However, it was established from the results that though communal rangelands provided commercial products capable of generating household income, rangeland users trading such products were receiving meagre incomes. This might be caused by the lack of institutional support to rural households thus, the low incomes received from communal rangelands. To that effect, main communal rangeland products such as, fuel wood, poles and medicine were cited as being more valuable for local domestic use than for the external market. Regression estimates further indicated that participation in communal rangeland products harvesting is more conditioned by perception-related factors as compared to socioeconomic attributes of rural households worth understanding for strategic targeting to promote their conservation. The extant literature and the study results, evidently show that communal rangelands provide a livelihood among rural households although it has a low direct household income potential. Therefore, the respondents were of the view that the use of campaigns targeting several perceptions (such as communal rangelands act as a source of medicinal plants, arable land and income etc) as suggested by the regression estimates may be very useful. The support from the extension department and further research may be necessary for purposes of quantifying harvestable rangeland products capable of enhancing rural livelihoods. Moreover, the observed low income potential of communal rangeland products suggests several technical and institutional challenges worth addressing to promote value addition of rangeland products.

- Description: This study analyses the housing price volatility in metropolitan areas in South Africa, particularly Port Elizabeth and East London residential housing markets. This study uses secondary statistical data, obtained from secondary sources. The study uses quarterly time series data for the period 1981:1 to 2015:3 giving 139 observations. The data will be collected from different sources. The main sources of data are real estate agencies (Trafalgar, Harcourts and Property24), the South African Department of Trade and Industry (dti) and supplemented by the South African Reserve Bank (SARB) and Statistics South Africa (Stats SA). The study shall use the ordinary least squares (OLS) method to estimate its results. Ordinarily, this is a generalised linear modelling technique that may be used to model a single response variable which has been recorded on at least an interval scale. This method requires that the underlying stochastic processes of the variables are stationary. That is, explanatory variables should exhibit constant means and variances over time. If the stochastic processes are not stationary, OLS produces unreliably significant coefficients. Results showed that household savings, household income and total growth in household buildings (TGH) are statistically significant in explaining changes in house prices. Jointly, all the explanatory variables can account for almost 52% of the changes in the dependent variable. The Durbin Watson statistic showed that there is no autocorrelation in the model. This shows that the model is good. Results from the regression show that there is a negative relationship between house prices and household savings. A one-unit increase in household savings leads to a 0.407 decrease in house prices. This relationship makes economic sense because when households save, there is less income available to buy houses. When there is less income available to buy houses, it would mean there is less demand for houses.

- Description: A review of the literature revealed that firms are inherently influenced by leadership in the upper echelons of the organization. The seminal paper of Hambrick and Mason (1984) has sparked much interest in the realm of organizational leadership. Studies involving organizational leadership have concentrated on leadership styles, the manner in which leadership takes place, leadership succession and organizational performance in an attempt to understand the dynamics of the senior leadership of organizations. Research has also explored how changes in the top management of firms has impacted its performance. This research has primarily been concerned with how a firm is impacted, once succession takes place, and has focused on financial performance, change in strategy and stockholder reaction (Shen & Cannella, 2002; Barron, Chulkov & Waddell, 2011; Friedman & Singh, 1989). Although their predisposition will largely influence the manner in which the incoming CEO acts, the literature has largely neglected the role the incoming CEO must fulfil, and how he/she steers the company, once appointed. In response, the following aim was developed to address this gap: To describe how the roles of two CEO's of the same company differed, during different time periods. The CEO assumes various strategic leadership roles, which they carry out in the context of their new environment once succession has taken place. From the literature, six strategic leadership roles were identified, which formed the foundation of this study. These were strategy formulation, strategy implementation, developing organizational culture, emphasizing ethical practices, managing the firm's resource portfolio and establishing balanced controls. The study set out to comparatively analyze two CEO's of the same firm during different periods. Both CEO's were investigated from the perspective of strategic leadership roles, allowing a comparison of their behaviour. The study analyses and describes these roles, and how they differed between the CEO's, in reaction to differing situational factors and in the context of succession. The study employed a deductive qualitative case study research design. This allowed the researcher to examine the complex phenomenon which have previously been studied at a more superficial level using quantitative methods (Baxter & Jack, 2008; Parrino, 1997; Jooste & Fourie, 2009). A qualitative methodological approach allowed the researcher to examine the topic through a lens which takes into account human variables and processes (Baxter & Jack, 2008). Data was sampled using purposive and convenience sampling while applying the critical incident technique. Data was collected through information sources such as news articles, press releases, annual reports, online interviews, news websites and other documents. Thematical analysis was used during the analysis phase of the study and allowed for patterns and links to be drawn between the collected data. The succession from one CEO to the next served as the comparative element of the study, which allowed for a contrasting of how both CEO's carried out their strategic leadership roles by adapting to their environment, and how they guided the strategic trajectory of the company. The study also took into account what both CEO's were confronted with at the start of their tenure and how this influenced how they carried out their leadership roles. It was found that Cynthia Carroll exercised her roles in a manner which addressed ethical and stakeholder engagement issues within the business. This was translated directly into how she guided the trajectory of the company. Upon appointment, Mark Cutifani exercised his roles in a manner which addressed the organizational performance and financial well-being of the company. This translated directly into how he shaped Anglo's trajectory in an attempt to better its financial performance. Given how they exercised their strategic roles in the company, each CEO influenced Anglo American's direction in a different way, which in turn, influenced the performance of the organization. It was shown that Cynthia Carroll improved the stakeholder engagement, communication and safety within the company, demonstrating behaviour that emphasized the importance of the ethics of the company. When the business had been carrying out its ethical practices effectively, but underperforming financially, Cutifani demonstrated the roles which would be geared toward resurrecting the organizational performance of the organization. Recommendations are made for further research including applying the same research method to investigate how these roles are carried out in companies which operate in a broad spectrum of industries.

- Description: My collection of short stories is set mostly in Gauteng and revolves around mainly the lives of the urban, black elite almost three decades after the first non‐racial elections in South Africa. It captures emerging trends and fault lines and enquires into whether South Africa can continue on a different path from that of the rest of the continent. Themes covered in the collection, which still espouses idealism, include the acquisition of power, status and money, the use and abuse of these, as well as the psychosocial effects of money on this group. My writing is inspired by the courageous, inventive and introspective writings of the Drum generation of writers William Bloke Modisane, Nat Nakasa and Can Themba, as well as the use of language and the experimental form of writing as embodied in the work of Lidia Yuknavitch to deal with similarly pressing social issues of the day.

- Description: Organisations of the future have to focus strongly on sustainability to meet the needs of and ensure the survival of future generations. Many organisations either ignore environmental issues or address these issues superficially. To become a green organisation, requires a change in attitude, knowledge and behaviour and therefore a change in organisational culture. The purpose of this study was to explore Human Resources strategies for developing and implementing a green organisational culture in organisations. To address the main problem and the identified sub-problems, a literature study was undertaken. The concept of sustainability was explored, the rationale for going green and major stakeholders in creating a green organisational culture were identified. The literature study provided a synopsis of previous research on HR strategies for managing a culture change and more specifically, for creating and implementing a green culture in organisations. The research revealed that leadership, communication, recruitment, orientation, training, performance management, reward and recognition initiatives, as well as discipline, could be used to develop green values, attitudes and behaviours among organisational members. A web-based survey with a questionnaire as data collecting instrument was conducted among public and private organisations in the Nelson Mandela Bay Metropolitan area to determine the extent to which these organisations used the identified HR strategies to create a green organisational culture. A snowball sample technique was used. The main factors surveyed, included leadership, green technologies, green communication, HR strategies and procedures, brand communication and brand image. The results confirmed that executives or senior management were the main drivers to create a green culture; however, even though these leaders were considered passionate about the environment, they did not optimise the vision values and strategy to build a green organisational culture. The study also confirmed that although these organisations used green technologies to reduce waste, they did not encourage or reward employees for their contributions to green initiatives and did not adequately use communication in this respect. The results revealed that of the factors surveyed, leadership and HR strategies or procedures contributed the most to organisations developing a green organisational brand or image. The study confirmed the importance of using an integrated approach to develop a green organisation. Such an approach is initiated by senior management, through the formulation of a green vision, green values and a green strategy, and is supported by both technological resources and employee contributions. In addition, HR strategies should be aligned vertically and horizontally to develop an appropriate green mind-set and behaviour among all organisational members. In this respect, the HR department should also model appropriate green behaviours.

- Description: The UNESCO site known as the Cradle of Humankind World Heritage Site (COH WHS) is a globally important cultural heritage area that hosts some of the oldest discovered hominid fossils and is a major contributor to our understanding of the evolution of modern hominids over the past 3.5 million years. The area is locally referred to as the Cradle of Humankind that flanks a densely populated region in South Africa, and which hosts a large sector of the Witwatersrand Basin, known as the West Rand. The Witwatersrand Basin contains the world’s largest gold deposits, some of which have been mined for more than 130 years. This study characterises the West Rand mine drainage to determine the extent of the hydrochemical interaction within the COH WHS and beyond. The hydrochemistry of surface waters was analysed across a sub-catchment draining the West Rand, using standard q-ICPMS and IC techniques. A total of 32 samples were collected quarterly for an annual cycle during 2011 to 2012. The median data were used for standard hydrochemical classifications for surface waters and two mine water classification systems. This is the first time this type of quantitative and comparative study has been performed in South Africa. The results of these classifications show that the mine drainage generated from the West Rand Goldfield can be described as an acidic (pH = 3.19 to 3.36), highly metalliferous (ΣMetals = 2564 to 3 141 μg/L) mine drainage, and with (SO42- = 3217 to 3532 mg/L) and (TDScalc = 3217 to 3536 mg/L). This mine drainage has been allowed to discharge continuously into the environment for fifteen years following the flooding of the mine voids in 2002. The extent of the mine drainage signature was determined to flow through the southern portion of the COH WHS and into the Crocodile River up to 54.2 km (CA24) downstream of the point source from Randfontein Estates mine property in the West Goldfield. In addition to the surficial contamination, there is evidence of groundwater – surface water interactions within the karstic terrain of the COH WHS. The findings highlight the need for on-going monitoring and further research to determine the possible consequences that acidic mine drainage discharge has on the environment and on the yet undiscovered fossils within the cave systems of the COH WHS. The GARD and Ficklin mine water classifications are used and compared in this thesis. A single universal hydrochemical classification system, capable of becoming a globally robust and standardised approach for mine waters is a valuable contribution that is needed within this field of study, along with the inclusion of uncertainty presented graphically in a clear and unambiguous way. Research is needed to provide realistic solutions that can be implemented to mitigate potential negative outcomes identified and that are in-line with national and global legislation to preserve and protect this world heritage area. The study has implications for mine water legislation and monitoring in areas of active and historic mining, and for water resource management.

- Description: My thesis is a weave of short stories, flash fiction and vignettes of prose-poetry. It uses lyrical, scenic and explorative modes to explore the stories of women, past, present and future, from all walks of life. These women, young and old, struggle to find their way within a ‘world’ characterised as Salithambo (the pink castle) whose structures and survival preys on their bodies. The stories explore the themes of girlhood and maturation, violence (specifically against women), animality, scatology, time, gender roles and expectations, and their rejection. I draw inspiration, stylistically, from Irenosen Okojie’s depiction of beauty and terror in the same sentence; Selah Saterstrom’s fragmented plot and directorial stroke; Taban Lo Liyong & Amos Tutuola’s avant-gardism and amplification of language; Adania Shibli’s sensorial and spare prose, Lyudmila Petrushevskaya, Lily Hoang & Carol Oates’ normalized magic spell, Athena Villaverde & Espido Freire’s imaginative overload of childhood; Shelley Jackson & Chevisa Woods’ construction of body parts as bearing texts or as texts themselves.

- Description: This treatise is born out of preoccupation with Identity, Culture and Architecture. Through the study of the fragility of the South-African Chinese community: their double heritage, their quest for a sense of place and permanence with the establishment of Chinese Schools that maintain the Chinese culture. It begins with identifying their almost unstable and fragmented nature of movement, their struggle to find a ‘place’ in Port Elizabeth, especially after the establishment of the Group Areas Act of 1960 and their fight against apartheid and discrimination. It becomes clear that migration, racial segregation, confusion, forced removals, and displacement have been their legacy in South Africa. The purpose of this document is to investigate the symbolic nature of architecture, and how it can be used as a tangible medium to bring about an affirmation of identity, and create a sense of place for the future; giving credence to the celebration of culture and social interaction. Through the use of literature reviews, informal interviews, desktop research, analysis, precedent studies and other qualitative studies; there will be an understanding of the community in terms of how they came about settling in South Africa; their migratory patterns due to forced removals and the current status of the community in terms of cultural revolution; understanding the cultural issues the community face; in the establishment of a centralised symbolic precinct that allows for the celebration and promotion of culture. Through the design of the Chinese Cultural School, it will be demonstrated that in order to create a sense of place for the Chinese community, aiding in integration and restoration; one will need to engage in the argument of the vitality of authentic architecture, the vernacular language of a particular culture, and the subjectivity of identity especially in a context outside of its homeland.

- Description: Numerous surface water bodies in South Africa face serious challenges of eutrophication despite several initiatives from government to solve the problem. Government efforts have not been successful particularly because of three issues: 1) insufficient and inconsistent water quality data and 2) the costly nature of collecting this data. Third, the limited uptake of remote sensing based technologies in water quality management due to lack of skills, as well as the lengthy and complex procedures involved in retrieving water quality parameters. This thesis aims to explore the possibilities of using satellite data and simple software for mapping and collecting water quality data. The broad goal was to determine the function of software dedicated to meet the requirements of a remote sensing-based eutrophication-monitoring system. Two specific goal were set in this study: 1. To extract software requirements from available eutrophication management documentation. This was necessary to determine the functions of the dedicated software that matches the legislative requirements and 2. To determine a design capable of handling spatial and temporal requirement of a remote sensing based eutrophication-monitoring system. The study applied Goal Based Requirement Analysis Model [GBRAM] model to extract goals from the National Eutrophication Monitoring Programme [NEMP] implementation plan document and recent publication on remote sensing of water quality monitoring conducted in South Africa. Afterwards, the study used object-oriented concepts to model suitable data objects and processes to implement spatial-temporal requirements of a remote sensing-based eutrophication-monitoring system. Based on the study findings the following are essential functions of a remote sensing based eutrophication-monitoring system. A graphical user interface that allows the user to set up a monitoring programming. Automated image processing procedures. Data assessment methods used to generate eutrophication status information. Numerous display options for viewing data in several perfectives.

Many South Africans are the victims of poverty and unemployment and, as a result, may face food insecurity, hunger and have diets lacking diversity. Malnutrition is commonly noted in patients with TB. Poor immunity as a result of TB further compromises the nutritional status of the patient and thus the prognosis. Chronic hunger together with food insecurity and inadequate dietary diversity can lead to poor drug adherence amongst patients. This highlights the fact that dietary factors may pose a threat to TB drug adherence. There is limited information available regarding the impact of dietary factors on drug adherence and the nutritional status in patients with TB, especially in the Eastern Cape. This emphasises the need for more research focusing on the impact that dietary factors have on drug adherence and nutritional status of patients with TB from underprivileged areas. The aim of the study was to describe the impact of dietary factors on drug adherence and the nutritional status of patients with TB from underprivileged areas in the Nelson Mandela Bay Health District (NMBHD) in order to revise current guidelines to standardise the nutrition management in patients with TB who are initiated on treatment. A descriptive, cross-sectional study was conducted using a quantitative approach. Ethical approval was obtained from the Research Ethics Committee (NMU) and the Eastern Cape Department of Health Provincial Research Committee. All participants provided written, informed consent prior to participation. A representative sample was drawn from each of the three sub-districts in the NMBHD to include a total of 256 participants. The following clinics were randomly selected: Max Madlingozi, Tshangana, Soweto clinic (sub-district A), Laetitia Bam, Middle Street, Rosedale (sub-district B) while clinics in sub-district C included Korsten, Walmer, Gelvandale and Helenvale. The population for the study included patients with TB older than 18 years treated at these specific clinics. Patients with Drug- Resistant TB were excluded. A structured interview was conducted by the researcher and three fieldworkers to obtain information on socio-demographics, drug adherence, food insecurity and dietary diversity. Anthropometric measurements (weight and height) were also obtained to determine the nutritional status of participants. The majority of participants were male (59%; n=150). The mean age of participants was 35,03 years (SD=11.97). Of the total sample, 70% (n=179) reported being currently unemployed, while 59% of the total sample were also unemployed prior to TB diagnosis. Fifty percent of participants (n=127) were HIV co-infected, while only a marginal percentage (3%; n=7) had Diabetes Mellitus. Treatment adherence was considered 'good' as 94% (n=240) reported taking their TB treatment daily while 92% (n=121) reported taking their antiretroviral therapy (ART) daily. About a third (32%; n=81) of the total sample experienced low appetite, followed by nausea (21%; n=53) and vomiting (20%; n=50). A large percentage (48%; n=123) of participants experienced severe hunger. The mean individual dietary diversity score (DDS) for this sample was below 3 (2.81/9) and could be classified as being moderately diverse. Forty-three percent (n=110) had a low DDS of 2 or less food groups. Only 2% (n=5) had a high DDS of more than 7 food groups. A statistically significant association was found between employment status and food insecurity and poor DDS. Previous TB infection was also significantly associated with food insecurity and poor DDS. Although so many participants were food insecure, 74% (n=188) reported taking their TB treatment with food. Regarding substance use, 24% (n=88) consumed alcohol weekly, whereas 31% (n=80) of participants smoked cigarettes. The mean BMI value for males was 20.93 kg/m2 (SD=4.19) and for females at 20.91 kg/m2 (SD=5.10). However, 30% (n=76) had BMI values below 18.5 kg/m2 and 16% (n=40) had BMI values above 25 kg/m2. Majority of the participants (91%; n=233) had lost weight prior to data collection. Furthermore, 75% (n=175) reported having experienced involuntary weight loss in the preceding 3 months, while 17% (n=43) reported having lost more than 10% of their body weight in the last 3 months. Almost all participants reported taking their TB treatment as prescribed. However, the study results echo the findings of other studies that a large cohort of participants are currently unemployed and food insecure. Many participants were consuming monotonous diets, consisting primarily of starch with little vegetables and fruits. As a result, the nutritional status of the sample population was compromised. This sample also reflected unhealthy lifestyle habits which included substance use (alcohol and cigarette smoking). As so many participants self-reported adhering to TB treatment, it was challenging to determine the impact that dietary factors have on TB drug adherence. Government, NGO's and other private stakeholders should make nutrition a priority especially in vulnerable groups such as patients with TB. Dietitians and nutritionists should be involved in the care of all patients with TB by providing relevant nutrition counselling. Although malnourished patients with TB are currently receiving nutrition supplementation, the amount and sustainability thereof should be revised. Food gardens may further be a safety net against food insecurity, hunger and inadequate dietary diversity.

- Description: Small hydro power sources have been identified as one of the renewable energy technologies that the South African government is focusing on in order to generate more electricity from renewable/independent resources. Due to the low carbon output of most renewable energy technologies and the carbon intensive power generation technologies that are currently being used in South Africa e.g. Hydro, coal, gas, and etc. further pressure is increasing to incorporate cleaner forms of generation. In 2002 a study focusing on the hydropower potential was compiled providing an assessment according to conventional and unconventional possibilities for all the provinces. Nowadays, the power electricity demand is growing fast and one of the main tasks for power engineers is to generate electricity from renewable energy sources to overcome this increase in the energy consumption and at the same time reduce environmental impact of power generation. Eskom Distribution Eastern Cape Operating Unit (ECOU) was requested to investigate the feasibility of connecting a small hydro power scheme located in the Teebus area in the Eastern Cape. The Eastern Cape in particular, was identified as potentially the most productive area for small hydroelectric development in South Africa for both the grid connected and off grid applications. These network conditions are in contrast to the South African electricity network where long radial feeders with low X/R ratios and high resistance, spanning large geographic areas, give rise to low voltages on the network. Practical simulation networks have been used to test the conditions set out in the South African Grid Code/NERSA standard and to test the impact of connecting small hydro generation onto the unbalanced distribution network. These networks are representative of various real case scenarios of the South African distribution network. Most of the findings from the simulations were consistent with what was expected when comparing with other literatures. From the simulation results it was seen that the performance of the variable speed generators were superior to that of the fixed speed generators during transient conditions. It was also seen that the weakness of the network had a negative effect on the stability of the system. It is also noted that the stability studies are a necessity when connecting the generators to a network and that each case should be reviewed individually. The fundamental cause of voltage instability is identified as incapability of combined distribution and generation system to meet excessive load demand in either real power or reactive power form.

- Description: Facilities management is a profession that encompasses multiple disciplines to ensure the functionality of the built environment by integrating people, places, processes and technology. It combines management and business with the most current professional and technical knowledge to provide a people-oriented and effective work environment. The study has the following objectives: to determine whether pro-active planning in order to optimise sustainable physical infrastructure is currently being carried out; to determine whether the cost structure of facilities management is being analysed to ensure proper planning that is aligned with the budget and to determine whether the organisational structure of facilities management (FM) is developed and fully staffed with qualified officials and that it is being operated from the correct department. This will ensure that facilities management carries out its mandate of creating jobs. The mixed research methodology was used in this study as both quantitative and qualitative techniques were employed in gathering, organising and analysing information obtained from the participants. Pilot questions were distributed to all relevant managers within the Amathole District Municipality. The primary data was gathered from Directors, Heads of Departments (HODs), general managers, senior managers, unit managers and assistant managers with a view to ascertaining their level of understanding of the importance of facilities management (FM) within the Amathole District Municipality. The secondary data for this study was obtained from a literature review of relevant publications from various sources, such as reports, books, the internet and articles. From the respondents’ responses, it can be noted that facility management is of benefit to the organization in that it provides for cost value benefit, the development of policies, safety, good property management and an efficient security system. One of the main drawbacks is the lack of a facilities manager in the department. No Senior Manager has been appointed with the facilities management portfolio, which would assist the top management in making informed decisions. As a result, there is no facilities management strategy, policy or framework to guide the portfolio in the right direction.

- Description: It is important to note that control weaknesses are of two types. Firstly, design weaknesses are where controls are inadequately designed. Secondly, implementation weaknesses are where controls may be designed very well, but implementation by officials may be inadequate or irregular. Hence this study is about improving internal control systems in the public sector. The objective of this study is to determine how the Department of Sport, Recreation, Arts, and Culture can move from an unqualified audit report to a clean audit report. The researcher found that internal controls are very important in the operations of the department as a whole, especial in financial governance. The internal controls play an integral part in the organisation because all processes need controls as a tool to mitigate against the risks. In order for the department to prevent the emphasis of matter on audit reports or to achieve clean audit report, it must strengthen its internal controls. Although this study did not cover the issues of pre-determined objectives, implementation of internal controls is necessary for the improvement of reporting on performance information. The study concluded that the Department of Sport, Recreation, Arts, and Culture complies with international best practice pertaining to internal controls and financial reporting. The department has a great opportunity to obtain a clean audit report. It also has the potential to increase the effectiveness and efficiency of its internal controls by strengthening the functioning of the internal control committee, risk management committee as well as the finance committee (In Year Monitoring). The executive authority and senior management of the department are the people who should enforce the implementation of internal controls through the use of the internal control function of the department, although the audit committee assists in ensuring the effectiveness of these internal controls.

- Description: Leadership development is very important in business and much is often said about ‘growing’ leaders in business organisations. Leadership development cannot be achieved in one training course or programme, but should rather be an everyday practice of existing leaders. Leader development concentrates on individual leader development, enrichment or attainment of within-person competence while leadership development concentrates on relational development. This paper addresses and outlines how an all-inclusive method to leadership development and succession planning is needed for the employees of the Eastern Cape Treasury. It also looks at the willingness of the existing leadership in government to coach and mentor the youth of today to take on a leadership role when the current leaders exit the market. The head office in Bhisho for the Eastern Cape Treasury has 390 employees and in total, when combined with district offices around the Eastern Cape, there are 454. The questionnaire was sent out to 80 employees and 55 of those were filled and returned to the researcher. The targeted employees were those in the following positions: Administrative Officer, Assistant Director, Deputy Director, Director and Chief Director. The empirical results though showed that Autocratic Leadership and Satisfaction with Compensation Package had no correlation with Leadership development, whereas Organisational Culture, Senior Management Support and Participative Leadership Style showed positive correlation with Leadership development success. Implementing the recommendations might help with improving leadership development in the Provincial Treasury.
