- Description: This study is intended to contribute to the existing body of knowledge relative to social protection of Orphans and Vulnerable Children (OVC). It proffers recommendations on sustainable assistance mechanisms which will ensure effective support systems for improved quality of life for OVCs. The impacts of orphanhood and other vulnerability issues on children directly challenge social protection systems and how they support the wellbeing of the children. This presents grave threat to social and economic development as well as the wellbeing of children. Child Support Grant (CSG) is one of South Africa’s largest social protection programmes targeting vulnerable children. The effectiveness of the grants in addressing the concerns of the children is greatly dependent on how it is utilised. The aim of this study is for a review of the support systems for OVCs in South Africa, within the context of social grants to determine its viability to address the challenges of vulnerability. The study is informed by empowerment framework as theoretical paradigm; which postulates that people need to be empowered through sustainable programmes that enhance their capacities to realize their full potentials and become self-sufficient. The study reviewed and appraised relevant approaches that aid empowering OVCs in order to ensure that they are supported to move from state of helplessness to an empowered state. A quantitative research method was used for the survey, data analysis and review. A case study approach was adopted for the study. The population of this study consisted of selected families of OVCs and community volunteers in Port St. Johns and Ndlambe local municipalities of the Eastern Cape Province. The study findings show that the CSG is relevant in the context of providing the needed support for the OVCs, which will enhance their wellbeing and development. It identified CSG as a mechanism which supports the concept of ensuring that OVCs have an adult caregiver who supports them. It shows that the CSG is able to reduce the number of OVCs without an adult caregiver. xii The study identified that many of the caregivers of the OVCs do not have other source of income and this affects their utilisation of the grant to attend to the needs of the children such as caregivers who do not support the wellbeing of the children though they receive CSG. The findings did not identify many challenges with the functioning and management of the CSG scheme. The concerns identified by the study are related to challenges of accessing the grant. The findings show that the caregivers do not encounter obstacles while applying for CSG for reasons related to the fact that some of them are being assisted. It shows that most children that are eligible but are not receiving CSG were for reasons such as caregiver not applying on time for the child or lack of documents required for the application. The study further noted that it was mostly caregivers that were not assisted during the applications process that experienced difficulties. The study observed that supporting the needed infrastructure in resource constrained environment is necessary to assist the children. Building facilities for banking, health care, and recreation as well as educational facilities such as libraries and computer centres were identified as relevant in schemes that aim to improve the quality of lives of children. The study findings revealed that hunger and deprivation could be a defining factor, which influences a child’s interest in education. It concludes that the provision of CSG to families could have strong influence in determining children’s interest in education. The study identified other support systems in the community that complement the CSG mechanism. The supports includes the assistance to process the application for CSG as well as guidance in the utilisation of the grant; after school care programme which provides opportunity for children to receive additional educational support; and material assistance for OVC families. The supports were mostly through community volunteers of organisations in the communities. These supports were found to be useful in supporting the caregivers of the OVCs to support the children.

- Description: The main purpose of this study is to explore the factors that contribute to occupational stress as experienced by the Student Support staff in a Further Education and Training (FET) College in the Southern Cape. The Student Support staff has displayed many symptoms of stress over the past few years. This in turn has led to absenteeism, change in staff temperament, their feelings towards the College, motivation levels and a significant change in the staff’s day to day operations. Although the Head of Department for Student Support Services has engaged with the staff on numerous occasions to discuss the reasons for their experience of stress, no substantial reasons could be established in order to make the necessary changes in the department. No interventions that have been implemented to date have relieved the staff’s experience of stress. The researcher chose to use a qualitative, exploratory, descriptive and contextual research design to gain insight into the situation or phenomenon in order to identify the factors contributing to occupational stress and to identify measures that can be implemented to reduce occupational stress in the Student Support staff. The participants in this research included at least 10 Student Support staff within the Student Support Services Department at a Further Education and Training College in the Southern Cape. Purposive sampling was used in this research study. Interviews will continue until data saturation is achieved. The staff members must have been employed for at least one year in the Student Support Services Department. The researcher will make use of semi-structured interviews, observations and field notes. The data will be systematically collected and meanings, themes and general descriptions of the experience analysed within the specific context (de Vos, Strydom, Fouche & Delport, 2005). The researcher will make use of Tesch’s method of analysis, and use Guba’s strategies for ensuring Trustworthiness. The researcher will apply the ethical considerations of confidentiality, informed consent, ethical approval from relevant institutions, avoidance of harm to participants, truthfulness and the debriefing of participants when conducting this study. The findings were reported as three major themes and subthemes. The three major themes were; Student support staff identified several factors that contributed to occupational stress, Student support staff identified the effect that occupational stress has on them, Student support staff offered suggestions that the college could implement to reduce occupational stress. These themes were discussed and analysed in-depth.

- Description: With the growth in the use of technology in sports, there has been an improvement in sporting performances. Some may argue that the two go hand in hand, while others will write it off as coincidence. Nevertheless the use of technology in sport is seen on a daily basis. Cricket uses Hotspot, tennis uses Hawk-Eye and rugby uses slow motion video replays. In these sports codes, technology is already an aid to umpires. Little is known, however, about the technologies used to assist coaches in sports codes such as netball. This study investigated the factors impacting the introduction of information technology in the coaching of netball. The study commenced with using the term technology in the broader sense of the word to gain an understanding from netball coaches as to how technology could be incorporated into the sport. It was later narrowed down more specifically to computer technologies. The investigation was done at the Spar National Netball Championships in 2012, where coaches were surveyed about the preparation for the tournament of the provincial teams. The surveys included questions to coaches regarding the technologies used in preparation for a national tournament. The results obtained from the coaches were used to identify the current technologies used. Interviews were conducted after the analysis of the initial results to probe into the potential use of social media as a tool to assist coaches. Based on the results of the study, a number of factors that impact on the introduction of technology in the coaching of netball were identified. The factors and basic guidelines were validated through expert focus groups. Based on the findings from the experts, the factors and guidelines were refined. It is envisaged that the findings from this research can be used to assist netball coaches in deciding how to introduce the use of information technology into the sport.

- Description: Employee participation is a common and popular aspect of most labour relations systems in many countries, including South Africa (the RSA). For years now, there have been debates around the actual benefits of employee participation initiatives to both the business and its employees. Various factors influence the development of participation initiatives within businesses. Some of these factors include legislation, management perceptions and attitudes, socio-economic factors, political and business complexities. These factors vary from one economy to another, from industry to industry, from company to company and may be classified into internal or external factors. It is even suggested that participation initiatives and levels of implementation may be different within the same organization, from department to department, and from one geographic set-up to another within the same organisation. It is for this reason that this research was undertaken. RoyalServe(RS) has an average of 12 000 employees and about 800 sites or branches or units within the RSA. A number of employee participation models and initiatives exist within RS, and it has been argued by many (inter alia trade unions, employees, managers) that the implementation of these models varies from one site to the next - with one of the major influencing factors being the size of a branch or site. Employee participation initiatives and models are established either voluntarily or in response to compliance with legislation. Some scholars and practitioners have suggested that employee participation models that yield positive results for both parties are the ones that are voluntary and have not been undertaken for legal compliance purposes. Others argue that even in cases where it is legislated and practiced for compliance, the end result remains the same. From a comparative point of view, the Japanese and German models of employee participation have been, for some time now, crowned as classic examples of employee participation. Interestingly, the two models (Japanese and German) were implemented for contrasting reasons. The Japanese model is voluntary whereas the German model is legislated. Both models remain leading examples of how successful participation can be, regardless of the reasons for its implementation. Royal Serve Cleaning operates in three Sub Saharan countries: South Africa, Lesotho and Namibia (making it a transnational organisation). The Head Office is situated in Midrand, Johannesburg, RSA. The following regional offices exist to provide immediate and more flexible support to both employees and clients at regional level: Cape Town: Western Cape; Midrand: Gauteng Province, Limpopo, North West and Mpumalanga; Bloemfontein: Free State, Lesotho and Northern Cape; Durban: KZN; Port Elizabeth: Eastern Cape; Namibia.The primary goal of this research was to investigate how the size of a site influences the implementation of employee participation within RoyalServe Cleaning (Pty) Ltd. Put differently, the question to be answered by the research is: are employee participation initiatives applied similarly across all sites within RoyalServe regardless of size? Another question that has been answered in this research report, albeit indirectly, is: do RoyalServe employees understand the various participation initiatives in place at all levels of the organisation? Accusations have been leveled by some employees that employee participation initiatives at RS are benefiting only those employees based at the big sites at the expense of the smaller ones. The research methodology followed in this paper includes: A review of the available literature about RoyalServe employee participation strategies, initiatives, minutes, reports and practices; The development of a questionnaire which was then distributed to selected employees at all levels within the organisation. The analysis of information gathered in the above activities and recommendations formulated was based on gathered data.

- Description: Organizations assist employees to deal effectively with demanding work and the work environment, including their personal problems, through an Employee Assistance Programme (EAP). The essence of the EAP is the application of knowledge about behaviour and behavioural health to make accurate assessments, followed by appropriate action to improve the productivity and healthy functioning of the employees. According to the report from the Employee Wellness Directorate of the Eastern Cape, the Employee Assistance Programme Practitioners saw 576 employees in 2010. These statistics only represent a few districts in the Eastern Cape as some districts do not have Employee Assistance Practitioners offering employee assistance, hence this number could be higher. In some instances employees do self-referral, which may increase the number without the managers knowing who is utilizing the EAP. This makes it difficult for the managers to monitor such employees and the effectiveness of the intervention rendered. Managers refer employees but do not have control over whether employees made use of the EAP and on the progress in sessions as they do not always receive the feedback. The Employee Assistance counsellor may receive a written referral from the nursing manager and then consults the referred employee in private. The employee gives consent and then the EAP counsellor addresses the problem at hand. If it is a complex case needing expert intervention arrangements are made. If the intervention requires follow up sessions, the EAP counsellor makes the necessary arrangements through the referring manager until the problem is resolved. The EAP counsellor monitors the employee and asks the manager to support the employee without divulging details of the problem that was being addressed. However, the Nursing Managers do not know how effective the programme is and whether the employees benefit from the use. The above-mentioned problem led the researcher to ask the following questions: • What are the perceptions that Nurse Managers in the Department of Health in the Eastern Cape Province have of the effectiveness of the Employee Assistance Programme? • How can Nurse Managers optimize employees’ use of the EAP? The goal of this study was to identify the perceptions of Nurse Managers of the Employee Assistance Programme in order to determine how the programme’s use can be optimized. The researcher used a qualitative, explorative, descriptive and contextual design. The research population was selected purposively and included the Nursing Managers in the Department of Health in the Chris Hani District, Eastern Cape, who have referred employees to the Employee Assistance Programme. Semi-structured interviews were used during the data gathering process. Interviews were conducted at a venue convenient to the participants. Open-ended questions were asked to enable participants to express their perceptions on the topic. The researcher also used observation and field-notes to ensure that the data gathering provided rich information. The data was analysed using Tesch’s method of data analysis. Trustworthiness was ensured by using Guba’s model of trustworthiness. The ethical strategies of informed consent, confidentiality and anonymity, avoidance of harm and voluntary participation were ensured. Two themes emerged from the data analysis. Theme one showed that the participants had contrasting perceptions regarding the effectiveness of the current Employee Assistance Programme. Some felt that they have benefitted from the programme while others felt differently. Theme two described the participants’ views elated to improving the utilization of the EAP. Positive and negative factors that impacted on the implementation of EAP have been identified. Results show that both the employer and the employees could benefit if EAP is well implemented. Decentralization of EAP could be very cost effective and could save the employer thousands of rands because resources would be utilized better.

- Description: The main objective of this dissertation was to investigate how cold rolling process parameters could be optimised to improve surface quality of the AA 3003 H22 treadbright coils. This treadbright product is one of Hulett Aluminium’s main products and is exported mainly to the North American market. One of its critical requirements is a defect-free bright surface. The literature review was conducted with particular focus on the effects of selected parameters or settings with respect to surface quality and a chapter outlining these aspects has been included. It was clear from the literature review that selected parameters do affect the surface quality and if adjusted accordingly can improve surface quality on treadbright coils. Subsequent chapters after the literature review outline how the tests were conducted, procedures followed and equipments used from the cold rolling machine to laboratories. Surface appearance results after each parameter was adjusted, showed that the surface quality did improve and even got better when other parameters like the colouring roll angle and percentage reduction were adjusted.

All experiments conducted had no influence on the microstructure of the metal as it remained the same throughout each experiment. The same has been found with the mechanical properties as percentage reductions experiments led to no change in tensile strength, proof strength and percentage elongation. In conclusion, this research has proved that cold rolling process parameters selected did affect the product surface quality. If controlled they can be used to optimise the surface quality on the treadbright product as required by Hulett Aluminium and its customers.

- Description: The main objective of this dissertation was to investigate how cold rolling process parameters could be optimised to improve surface quality of the AA 3003 H22 treadbright coils. This treadbright product is one of Hulett Aluminium’s main products and is exported mainly to the North American market. One of its critical requirements is a defect-free bright surface. The literature review was conducted with particular focus on the effects of selected parameters or settings with respect to surface quality and a chapter outlining these aspects has been included. It was clear from the literature review that selected parameters do affect the surface quality and if adjusted accordingly can improve surface quality on treadbright coils. Subsequent chapters after the literature review outline how the tests were conducted, procedures followed and equipments used from the cold rolling machine to laboratories. Surface appearance results after each parameter was adjusted, showed that the surface quality did improve and even got better when other parameters like the colouring roll angle and percentage reduction were adjusted. Correct working limits within which each parameter would yield acceptable surface quality were also established. All experiments conducted had no influence on the microstructure of the metal as it remained the same throughout each experiment. The same has been found with the mechanical properties as percentage reductions experiments led to no change in tensile strength, proof strength and percentage elongation. In conclusion, this research has proved that cold rolling process parameters selected did affect the product surface quality. If controlled they can be used to optimise the surface quality on the treadbright product as required by Hulett Aluminium and its customers.

- Description: A person’s career takes up a large portion of his or her life for a minimum of 8 hours per day. A large portion of their time is spent performing their duties which are often accompanied by various demands or pressure that can result in an employee experiencing stress. Over time this build-up of stress due to job demands affects their ability to perform at work. This study aimed to identify, explore and describe the factors that facilitate the resilience of healthcare professionals working at a Campus Health Service at a Higher Education Institution. An exploratory descriptive study consisting of a qualitative nature was employed. Data was obtained from semi-structured interviews. The questions that were posed to participants read as follows: (1) “Tell me about the demands placed on you in your current work situation”, (2) “How do you cope with the demands placed on you?”, (3) “What can be done to assist you to cope better at work?”, and lastly (4) “Any additional questions/comments?”. The fourth question was added by the researcher in order for participants to have the opportunity to add to what they have said previously. Data was gathered until data saturation was reached. Tesch’s model of content analysis as well as Guba’s model of trustworthiness was employed, in order to analyse the data. An independent coder was subsequently employed to ensure the trustworthiness of the data. The findings revealed that all participants found workplace demands to be stressful, in terms of physical, emotional and time-related demands placed on them. Participants identified strategies that could help them cope with their demands such as open air activities, debriefing with colleagues or making use of a wellness line, maintaining a positive attitude, support from management and colleagues, the ability to practice initiative and autonomous decision-making, and lastly, religious practices. In addition, participants made recommendations on how employers can help relieve their stress. The recommendations included developing an in-house wellness programme, providing sufficient staff of the correct categories, providing adequate facilities and equipment to improve efficiency, providing developmental opportunities, scheduling training programmes for less busy times of the year, and lastly, introducing elements of structured flexi-time for employees.

- Description: Numerous teachers in South Africa are experiencing ill‐discipline within the classroom environment. They are not receiving the necessary support and guidance from the relevant departments, and thus, rely on their own reactive measures to manage the disruptive behaviour present in the classroom. Previous studies have shown that the South African Education Department has not provided all teachers with the necessary training needed to implement the new discipline strategies proposed by the Department of Education. Therefore, teachers rely on what they perceive to be effective in maintaining discipline, which is an indication of their personal teaching philosophy, as they base their own knowledge on what they have experienced and learnt in the past. This study followed a qualitative enquiry, which is descriptive and explorative. The data generation tools that were utilised for the study were, ‘drawing’ and ‘photo album’, both of which represent visual methodology activities. Furthermore, the primary aim of the study is to determine the underlying teaching philosophies that inform selected township teachers’ approaches to discipline in their classrooms. However, the findings indicated that the use of corporal punishment is still visibly prevalent in this township school. Even though it was revealed that the prominent teaching philosophy was not that of fundamental pedagogics, but featured somewhere in between the humanising pedagogy and Noddings’ theory of caring, the effects of teaching during Apartheid under the principles of fundamental pedagogics is still existent in the township.

- Description: Background: The World Health Organisation (WHO) initially recommended F100 formula in the treatment of severe malnutrition. F100 is made with full cream milk powder, sugar, oil and water with added minerals and vitamins. Ready to-use therapeutic food (RUTF) is a highly nutrient dense food enriched with minerals and vitamins, with a similar nutrient profile but greater energy and nutrient density than F100. RUTF has shown to be effective in the treatment of severe and moderate wasting and is associated with an increased recovery rate. In South Africa no studies are available on the recovery rate of children with severe acute malnutrition treated with RUTFs. Aim: To compare the recovery of clinically stable severe acute malnourished children, between the age of 12 and 60 months, treated with either F100 or RUTF as nutrition supplement. Methods: A randomised clinically controlled trial was performed. All children referred to Clairwood hospital with severe acute malnutrition (SAM), defined as a weight for height measurement of <70 percent of the median and/or < -3 SD below the mean WHO reference values or the presence of bilateral oedema were included in this study. Children were stratified according to age and gender and subsequently randomly assigned with randomisation tables to either the RUTF or F100 group. A total of 35 children were included in this study and data from 34 were analysed with 17 in each group. Results: Most children included in this study were between 12 and 18 months with boys in the majority. Both groups had a large percentage of HIV-infected children (70 percent in the RUTF group and 76 percent in the F100 group), with Tuberculosis (TB) co-infection in some of the children. One child died due to HIV related complications. The rate of weight gain was 7.77g/kg/day in the RUTF group and 6.11g/kg/day in the F100 group. There was no statistical significant difference established between groups (p = 0.46). The majority of children recovered within 21 days on the RUTF while the majority of children in the F100 group recovered after 6 weeks. There were no changes in height during the rehabilitation of these children. MUAC changes were observed with 92 percent having a mid-upper arm circumference (MUAC) of > 11.5cm after a 6 week intervention with RUTF and F100. Conclusion: RUTF resulted in better rates of recovery and can be used efficiently in rehabilitating children with SAM in a supervised facility setting. These preliminary results also point towards significant potential savings regarding hospitalisation costs since faster recovery has been demonstrated by children in the RUTF group.

- Description: The aim of this study is to present information to members of the South African press, academics in the field of journalism as well as individuals of the South African public who have a keen interest in printed communication in South Africa. The information presented discusses the practice of self-regulation in the South African press, through a study of the Press Council of South Africa (PCSA), the Press Ombudsman and the Press Appeals Panel that is a non-governmental organisation to regulate the press in South Africa. This study will include an analysis of the functions of the Press Ombudsman, the PCSA, the Press Appeals Panel, as well as the role of the constitution of the PSCA and the South African Press Code, which the PCSA uses as a guideline for publications that subscribe to it. Furthermore, a study into the complaints procedure and the determination of the outcome will be done in addition to the sanctions imposed on publications and journalists in breach of the Press Code as well as the acknowledgement given to individuals who have lodged a complaint to the Press Ombudsman, and the article or publication they have complained against had been in breach of the press code. In addition, this study will analyse the outcomes of selected complaints submitted to the PCSA as well as an analysis of submissions made to the PCSA task team and the Press Freedom Commission, an independent commission that was set up to research the regulations of the press. It was found that the PCSA strengthened the system of regulation with the help of the public. It is apparent that the organisation took into account many of the points raised in public submissions. Although the system is self-regulatory it is important to take note that it values and upholds the views of the public. Although though the sanctioning of wayward newspapers was not severe, it had become more defined in the amended code. A point of concern that did not improve over time is the time frame that the Press Ombudsman‟s Office took to resolve the disputes. The delays caused in some disputes were caused by loop holes in the press code and complaints procedure as well as defiant journalists. The PCSA is currently being restructured. As a society changes, the press industry needs to adapt to its needs. This means that the press code will have to constantly be developed to suit society‟s rapidly changing needs. The PCSA has attempted to meet those needs by constantly changing to ensure that the regulatory structure remains relevant.

- Description: Contemporary performance poetry is a democratic art form that elicits dialogue and is a catalyst for social change. Yet it is an art form that is still not well understood: it is accused of unconsciously mimicking hip-hop and being a watered-down, lesser version of "real" poetry. However once its power is harnessed it may be a powerful art form that can be used to address social ills and act as a medium for memory work. The themes that are prevalent in contemporary performance poetry illustrate society‘s preoccupations. Different South African and American poets from a wide range of socio-economic, national, generational and racial backgrounds are examined to explore the collective preoccupations that keep emerging in the poetry, issues pertaining to race and class, gender, and to the politics of the past and its effect on the present. There is a long debate around the influences of contemporary performance poetry, which is negotiated in Chapter One. Though Gil Scott-Heron‘s "The Revolution will not be Televised" is identified as being a major influence, Saul Williams‘s "Black Stacey" challenges some of the arguments made by Scott-Heron. Lesego Rampolokeng lays the foundation for South African performance poetry by criticising the new black elite in the country in "Riding the Victim Train". Chapter Two examines how the poets challenge the status quo in their work. Sarah Jones‘s "Blood" illustrates how the new black middle class in America is complicit in keeping poor people on the margins, while Kgafela oa Magogodi levels his criticism against state sanctioned poets in South Africa. Mxolisi Nyezwa‘s "The Man is Gone" illustrates that the new class based hierarchal system in South Africa is potentially harsher than the apartheid one that was based on race. Chapter Three focuses on gender issues that are prevalent in South Africa. Tumi Molekane‘s "Yvonne" illustrates the danger that is embedded in the hetero-normative narrative while oa Magogodi‘s "Samson and deli(e)lah" and Sam‘s "Eve" explore how this narrative is unjustly informed by misinterpretations of the Bible. History and the impact of the past on the present is the focus of Chapter Four. "76" by Molekane illustrates how the apartheid legacy still affects many in South Africa, while Andrea Gibson‘s "Eli" explores the devastating effects of America‘s war efforts in Iraq. Dennis Brutus highlights the cathartic attributes of poetry that is community-driven in "So Neat They Were" and "Mumia". The chapter ends with an exploration of how the form of izibongo is used by Chris Thurman in "Holy City (A Jozi Praise-Poem)". The last poem illustrates how the past informs the present and suggests that despite the bleakness of the past, there is hope for South Africa because of its rich cultural heritage.

- Description: Part II of the International Labour Organisation Convention 158 recognises operational requirements of an organisation as a ground for dismissal. Section 213 of the Labour Relations Act describes operational requirements reasons as requirements based on the economic, technological, structural or related needs of an employer. The employer‟s needs in case of operational requirement dismissal must be separated from the other reasons for dismissal, such as misconduct and incapacity. Operational requirements dismissals are governed by section 189 of the LRA. The LRA draws a distinction between small and large scale dismissals and regulates them separately. Section 189 control small scale dismissals, while section 189A pertains to large scale dismissals For substantive fairness of a dismissal for operational requirements, the employer must prove that the said reason is one based on operational requirements of the business. The employer must be able to prove that the reason for the dismissal falls within the statutory definition of operational requirements. Employers are not allowed to use retrenchment to dismiss employees who they believe to have performed unsatisfactorily. This means that employers are not entitled to retrench for ulterior reasons, than those of operational requirements.The Labour Court has held that an employer may not under any situation retrench an employee on a fixed-term contract if the termination takes place before the contract of the employee ends, unless the contract of employment makes provision for termination at an earlier date. Retrenchment in this situation will amount to a breach of contract. Another point of interest in dismissals for operational requirements is that the Labour Relations Act states that it is not unlawful to dismiss a striking employee for reasons based on the employer‟s operational requirements. In relation to the selection criteria to be used during these dismissals, the Labour Relations Act again states that if an agreement cannot be reached between the consulting parties, then the employer must use criteria that are fair and objective.

- Description: Considering the challenges faced by the City of Cape Town such as loss of biodiversity, limited supply of energy and unsustainable land use, it is argued that it is imperative for the construction industry to promote sustainable development. The objective of the research was to understand the contributions of the construction industry to over exploitation of resources such as biodiversity, energy and land. Secondly, the study considers initiatives to be undertaken by the construction industry to enhance the environment so as to promote sustainable development. The research mixed methods was used as the form of collecting required data. The collection of data comprised of the design and administration of open-ended and closed-ended questionnaires among a non-random selected population of building contractor, public works officials and practising Architectural firms within the City of Cape Town. The data obtained from open-ended questionnaire on building contractors and public works officials was analysed qualitatively and data from the closed-ended questionnaires through practising Architectural firms was analysed quantitatively. Research results showed that biodiversity in the City of Cape Town is under threat. Passive design has a significant role in protecting the biodiversity and should be encouraged by the construction industry and the City of Cape Town. The City of Cape Town should strongly enforce polices that support the conservation of biodiversity. This will have a positive impact through encouraging the construction industry to adhere to these polices. The City of Cape Town is faced with energy shortage. The construction industry needs to reduce its energy usage as a dominant energy user. This will be achieved through energy efficient designs and retrofitting the existing buildings. The City of Cape Town has a responsibility to promote sustainable land use. Land prices are highly priced in the City of Cape Town as a result the poor cannot enter the market without external assistance. The construction industry has a role to encourage sustainable land use in the city.

- Description: Considering the challenges faced by the City of Cape Town such as loss of biodiversity, limited supply of energy and unsustainable land use, it is argued that it is imperative for the construction industry to promote sustainable development. The objective of the research was to understand the contributions of the construction industry to over exploitation of resources such as biodiversity, energy and land. Secondly, the study considers initiatives to be undertaken by the construction industry to enhance the environment so as to promote sustainable development. The research mixed methods was used as the form of collecting required data. The collection of data comprised of the design and administration of open-ended and closed-ended questionnaires among a non-random selected population of building contractor, public works officials and practising Architectural firms within the City of Cape Town. The data obtained from open-ended questionnaire on building contractors and public works officials was analysed qualitatively and data from the closed-ended questionnaires through practising Architectural firms was analysed quantitatively. Research results showed that biodiversity in the City of Cape Town is under threat. Passive design has a significant role in protecting the biodiversity and should be encouraged by the construction industry and the City of Cape Town. The City of Cape Town should strongly enforce polices that support the conservation of biodiversity. This will have a positive impact through encouraging the construction industry to adhere to these polices. The City of Cape Town is faced with energy shortage. The construction industry needs to reduce its energy usage as a dominant energy user. This will be achieved through energy efficient designs and retrofitting the existing buildings. The City of Cape Town has a responsibility to promote sustainable land use. Land prices are highly priced in the City of Cape Town as a result the poor cannot enter the market without external assistance. The construction industry has a role to encourage sustainable land use in the city.

- Description: Retirement has different meanings for different people. Retirement represents a significant transitional period in the life cycle of an individual. The aim of the study was to explore and describe the experiences and coping resources of retirees. The researcher applied an exploratory, descriptive research design employing the mixed methods of quantitative and qualitative research to gain an in-depth understanding of the phenomenon. A non-probability purposive sampling method was used to identify participants who retired from a specific vehicle manufacturing company in Port Elizabeth. Semi-structured interviewing techniques and a questionnaire called the Coping Resources Inventory were used for data collection. The rationale for using a mixed method approach was to increase the validity of the research findings. Descriptive statistics and the framework provided by Tesch (in Creswell, 2003) were used in data analysis of quantitative and qualitative data respectively. The results of the Coping Resources Inventory indicated that the participants perceived themselves as having an average level of coping resources. The results from the semi-structured interviews reflected that participants’ retirement experiences are mainly influenced by the following three factors: (a) economic resources, (b) social relationships and (c) personal resources. Recommendations were made for future research and intervention regarding retirement planning. The researcher included suggestions for the implementation of a retirement preparation programme. Lastly the limitations and the value of the study were outlined.

- Description: The human resource department in many organisations is at a crossroad of relevance, constantly being faced with the challenge to prove that it can add value towards the objectives of the business. The Human Resource (HR) department is also faced with a reality that, if the department does not add value to the organisation, it will be farmed out to independent contractors, who can deliver the HR functions at a more efficient and cost effective way. However, organisations have a great opportunity to achieve excellence and competitive advantage through the utilisation of the organisation‟s human resources. Many scholars and authors argued that organisations can achieve the most out of its human resources if the HR department is a Strategic Business Partner (SBP) in these organisations. A thorough literature review has led to the discovery that, despite the appraisal of the Strategic Business Partners (SBP) approach to the management of human resources, little progress has been made with the reinvention of the HR departments from support function towards being a SBP (Lawler & Morhman, 2003; Keith, 2007). The slow progress in the transformation of the HR department was attributed to a wide range of factors including the lack of competencies to take up Strategic Business Partnership roles, lack of management support, and incongruent organisational cultures (Keith, 2007; Sanders & Frenkel, 2009; Ulrich & Brockbank, 2005). Semi-structured interviews were conducted with HR professionals, Managing Directors and other Directors, who sit on a strategic table, to identify the challenges and opportunities the HR department faced as a SBP in organisations. A self-administered questionnaire, based on an existing questionnaire (Ulrich & Cornell (1997) HR role assessment survey) was used to gather the perception of employees regarding the roles the HR departments play in organisations. In this study organisational culture was identified as having a huge impact towards the implementation of HR departments as SBPs. The study also identified the competencies needed for the effective execution of SBP roles, the challenges HR departments may face in the process as well as the important roles the HR department should be devoting most of its time and resources to.

- Description: The objective of this study is to conduct a survey concerning the perceptions of educators in the Queenstown education district of the labour dispute resolution system. The education department is one of the biggest departments in the Eastern Cape’s Provincial Administration system. The likelihood of disputes is high when there are many employees. The focus of the study therefore is on how educators perceive the role of the department in terms of ensuring that labour disputes with the department are resolved efficiently and speedily. The advent of a democratic dispensation resulted in the ushering in of progressive labour legislation such as Labour Relations Act 55 of 1995. The objective of this Act is to facilitate economic development, social justice, labour peace and democratization of the workplace. In other words this Act gave birth to the manner in which labour disputes should be resolved. The study was carried out not only to explore the perceptions of educators but also with a view to making recommendations on the findings in order to help contribute towards labour peace and productivity in the workplace. The attitudes of one hundred and forty-one educators were surveyed via questionnaires and six educators who have had labour disputes with the department were interviewed. The key findings of the study revealed that both the educators who were surveyed and those interviewed lack confidence in the effectiveness of the labour dispute procedures in the district; they perceive the system as being inaccessible to them; time taken to resolve disputes is too lengthy; the system lacks necessary independence from the department of education or government and the department is seen as not adhering to its own policies and legislation. Hence there are many disputes and there is a great need for more awareness and for improved training in handling labour dispute resolution systems for district officials and educators. The study recommends more awareness and training sessions for both district officials responsible for labour relations and educators at large. It also calls for an increasingly proactive role by teacher unions in partnership with the department of education to avoid labour disputes. Although the findings cannot be generalized toother districts of the province, they do however highlight critical areas in labour dispute resolution where attention can be paid and focus made in order to ensure labour peace in the workplace for improved productivity and effective teaching and learning.

- Description: The South African government has endeavored to provide settlement to citizens and policies have been formulated since 1994 to guide these efforts. The South African Constitution (1996, section 26) stated that everyone has the right to have access to adequate housing. Furthermore the African National Congress’s Freedom Charter (1955) made it clear that: “there shall be houses, security and comfort for all, everybody shall have the right to live where they choose, to be decently housed, and to bring up their families in comfort and security. Slums shall be demolished and new suburbs built, where all shall have transport, roads, lights, playing fields, crèches and social centers”. However, after 19 years of democracy the state of housing is still a critical issue that addresses whether development has served to further the cause of sustainable development with respect to the pillars of human settlement such as shelter, infrastructure and economic opportunities. The study was conducted in the Litchis Bay settlement in East London, Eastern Cape Province. Mixed approaches of quantitative and qualitative methods were used to solicit data. Random Sampling techniques were conducted to select the sample population. Data was captured on Excel sheets to generate graphs. Findings of the study and conclusions were drawn. Therefore when measuring the term ‘sustainable human settlement’ against the findings on RDP houses in Litchis Bay, one can conclude that sustainable human settlement is not fully absorbed in defining the sustainability of RDP houses in Litchis Bay. Moreover the majority of houses have defects, and social amenities are not easily accessible.

- Description: Today’s production industry is faced with the challenge of maximising its resources and productivity. Tool condition monitoring (TCM) is an important diagnostic tool and if integrated in manufacturing, machining efficiency will increase as a result of reducing downtime resulting from tool failures by intensive wear. The research work presented in the study highlights the principles in tool condition monitoring and identifies acoustic emission (AE) as a reliable sensing technique for the detection of wear conditions. It reviews the importance of acoustic emission as an efficient technique and proposes a TCM model for the prediction of tool wear. The study presents a TCM framework to monitor an end-milling operation of H13 tool steel at different cutting speeds and feed rates. For this, three industrial acoustic sensors were positioned on the workpiece. The framework identifies a feature selection, extraction and conditioning process and classifies AE signals using an artificial neural network algorithm to create an autonomous system. It concludes by recognizing the mean and rms features as viable features in the identification of tool state and observes that chip coloration provides direct correlation to the temperature of machining as well as tool condition. This proposed model is aimed at creating a timing schedule for tool change in industries. This model ultimately links the rate of wear formation to characteristic AE features.

- Description: This study was intended to establish which polymer material is best suited as the material for bushes used in high force small oscillating angular contact applications as typically found in a large sugar mill coupling. A Tribometer as well as a designed and manufactured Bearing Testing Machine, which simulates and accelerates the wear caused in the intended application, was used to determine the wear rates and coefficients of friction for seven polymer materials. Materials were selected for their superior mechanical and thermal properties. The Tribometer was fitted with a linear reciprocating rig, so as to simulate the small oscillating movement prevalent in the intended application. Each Tribometer test ran for a duration of two hours with a frequency of 33.1 Herts and a normal loading of 40N. Bearing Testing Machine tests were done under similar constraints but with 30kN loading present on the surface of a bushes inner race. These tests had a longer duration of 24 or 48 hours or until intense wearing occurred. Initially both testing methods will be analysed independently of each other in order to try and identify a relationship between the wear rate and coefficient of friction for the different polymers. The different testing methods’ results will be compared to each other in order to establish if a correlation between the materials tested could be found.
