- Description: Cultivating oyster mushrooms (Pleurotus ostreatus) could have multiple advantages. For example, it can contribute to food security and malnutrition eradication, as a source of healthy and nutritionally rich food. Feeding on lignocellulosic crop/plant residues, these mushroom species also convert waste materials into a wide diversity of products which have multi-beneficial effects to human beings: serving as animal feed and fertiliser, and for protecting and regenerating the environment. Therefore, objectives of the current research were (1) to investigate the use of the rapidly increasing alien plants (Acacia spp.) in South Africa in cultivating of oyster mushroom for dual benefits, income generating and controlling the population of the alien (invasive) plants; (2) to evaluate the use of pineapple residue in the Eastern Cape as sole substrate or as a supplement in the cultivation of oyster mushroom; (3) to determine the effect of mushroom spent substrate, as organic growing media, on growth of tomatoes and controlling nematode population. In an experiment to investigate yield performance of oyster mushroom (Pleurotus ostreatus HK 35) grown on three acacia species [black wattle (BW: Acacia mearnsii) , silver wattle (SW: A. dealbata) and green wattle (GW: A. decurrens)] used as substrates either mixed with 50% maize bran (MB) or 50% wheat straw (WS).

- Description: Energy demand forecasting, and specifically electricity demand forecasting, is a fun-damental feature in both industry and research. Forecasting techniques assist all electricity market participants in accurate planning, selling and purchasing decisions and strategies. Generation and distribution of electricity require appropriate, precise and accurate forecasting methods. Also accurate forecasting models assist producers, researchers and economists to make proper and beneficial future decisions. There are several research papers, which investigate this fundamental aspect and attempt var-ious statistical techniques. Although weather and economic effects have significant influences on electricity demand, in this study they are purposely eliminated from investigation. This research considers calendar-related effects such as months of the year, weekdays and holidays (that is, public holidays, the day before a public holiday, the day after a public holiday, school holidays, university holidays, Easter holidays and major religious holidays) and includes university exams, general election days, day after elections, and municipal elections in the analysis. Regression analysis, cate-gorical regression and auto-regression are used to illustrate the relationships between response variable and explanatory variables. The main objective of the investigation was to build forecasting models based on this calendar data only and to observe how accurate the models can be without taking into account weather effects and economic effects, hence weather neutral models. Weather and economic factors have to be forecasted, and these forecasts are not so accurate and calendar events are known for sure (error-free). Collecting data for weather and economic factors is costly and time consuming, while obtaining calendar data is relatively easy.

- Description: Effective leadership has been found to be a key determinant of organisational success. Effective leadership does not only involve the ability to influence and inspire others, it is the ability to lead subordinates according to the competencies that they value. The focus of this study is on determining what in fact the future South African graduate workforce will value in a leader. Effective leadership and the competencies that subordinate's value is especially relevant today as leadership is forced to contend with an increasingly diverse workforce. This diversity necessitates the need for a leadership style to be congruent with what subordinates of diverse genders and cultures will value, so to be effective. Existing studies have indicated that gender and culture influence what subordinate's value in a leader, however it is evident from the results of this study, that this is not entirely the case. Regarding gender, the female and male respondents in this study value similar competencies in their leader, indicating that there is no distinct set of competencies that will be valued by male and female graduates. With respect to culture, the respondents value a mixture of competencies that combine both African and Western leadership practices, values and philosophies, indicating that there is no distinct set of competencies that will be valued by African, Coloured, Indian and White graduates. On the basis of this research, the recommendation is that for leaders to be effective in the 21 st century, a leader must be loyal and inspirational, have vision and integrity and lastly must be open and honest with their subordinates

- Description: The constant strive for improving the efficiency of production processes has become a worldwide challenge. In high speed production facilities response time between man and machine is of utmost importance when financial implications are taken into account. This dissertation contributes to improving the response time by making use of wireless notification between the machine and the maintenance technician when process faults occur. The tool used to achieve this is based on Android. Research is carried out on the latest Android technology while taking the safety aspects of a production environment into consideration. Research in designing a rule based intelligent system is established by using a tablet as the user interface for automatic notification and corrective action recommendations. Quick response is achieved by setting up a wireless network. As a result of designing a wireless intelligent maintenance tool, production downtime is improved. Management can recall all activities logged by the system for graphical representation.

- Description: This study emerged from the high prevalence rate of HIV and AIDS infection among women in Sub-Saharan Africa, which has no exception to Namibia. Women have been vulnerable to HIV and AIDS let alone on sex related issues since the epidemic emerged, but not research has been done specifically to Okalongo women. The way in which women vulnerable to HIV and AIDS infection were explored by examined social and cultural identities that affect women’s sexual relations in negotiating sex and safe sex. Qualitative study on a sample of fifteen women was conducted in Okalongo. The purpose of this study was to investigate the conceptions and experiences of women in negotiating sex and safe sex with their husband and partners. Feminist theory guided the methodology and analysis of data. I assumed that gender roles andsexuality are socially constructed, shaped by religion, social, political, and economic influences and modified throughout life. Feminist theory assisted in documentary the ways in which the female’s gender and sexuality in Okalongo is shaped by cultural influences and by institutions that disadvantage female and other oppressed groups by silencing their voices. The feminist further guided the discussion of the contradicting messages about women’s sexuality and their experiences, as women complied, conformed and even colluded with their oppression. To address the issue under study, the primary analysis of data from the focus group discussion and individual interview were utilised. The following themes were the heart of analysis: Women Positionality, Normalisation and Compliance, Women Agency and Male Dominance Power, Women Perceptions of Risk, Sex Education in and out of school among Women.In this study the data suggested that women in Okalongo are more vulnerable to their lack of assertiveness, as they have difficult in developing an authoritative voice, they tend to be humble about their achievements and knowledge and to only assertively when concerned about others. The findings supported the literature that women’s vulnerability is strongly influenced and tied by broader forces present in the society. Women’s vulnerability is real and needs to be tackled for any progress to occur in the fight against AIDS. Until factors that constraints and enabling women agency to negotiate sex and safe sex acknowledged and addressed, women will continue to succumb to the HIV pandemic.

- Description: South Africa is held up internationally as a beacon of good practice in terms of its efforts to promote gender equality and, the increased number of women in leadership positions in all spheres of government is testament to this. The representation of women in all spheres of government is advocated for and promoted by legislation and policies that aim to promote a gender focus on all government procedures and programmes. The purpose of this qualitative study was to explore the experiences of women leaders, including their reasons for maintaining leadership positions. It also addressed the challenges these women faced on their journeys and described their definitions of successful leadership based on their experiences. The qualitative nature of the research project made it possible to tell the stories of the participants’ experiences in order to understand their career progression and how it pertained to their concept of leadership. The three participants recruited for the study were women in positions of influence within their municipality including managers, directors, and executive directors. Purposeful sampling was used so that the chosen participants would have experience with the central phenomenon being studied. All of the women contacted to participate in this study readily agreed to share their experiences. There was some level of diversity regarding the age, ethnic backgrounds, and education level of the participants. Semi-structured personal interviews were conducted to collect the data. Open-ended questions were used so the responses of the participants could guide the development of themes and the direction of the study. Once the data were collected through recorded interviews, codes were assigned to sections of the text to help identify themes. A coding table was developed to illustrate how the themes for the discussion emerged from data obtained during the interviews. The stories of the participants were interwoven based on the themes and also analyzed in terms of the existing research. A discussion of the findings incorporated the literature and provided evidence of connected concepts. Strategies including inter-coder agreement, rich description, and clarification of biases were used to strengthen the study’s findings. Ethical issues were addressed throughout each phase of the study. All participants were asked to sign an informed consent form that outlined the procedures of the study. The identity of the participants was kept confidential through the use of pseudonyms.

- Description: This thesis will discuss how the application of place theory might provide insight into how a selection of Xhosa-speaking people in a rural village (Ntloko), in the former Ciskei of the Eastern Cape, interact with and establish relationships with the local indigenous thicket forest (ihlathi). I am concerned with how these influence residents' perceptions and attitudes (relational epistemologies) towards this resource, and how these may (or may not) translate into conservation practices. I am also interested in how socio-political and economic changes have altered these people/place relations (including gender) and their corresponding cultural perceptions. It is argued that the local thicket forest's significance and importance moves beyond the economic and utilitarian value of its natural resources. The thicket plays an important part in local identity construction, due to both its socio-cultural significance and its role in local livelihoods. People form meaningful attachments and relationships (relational epistemologies ) with the thicket as a place, through their interactions with it. While this may or may not result in actions and attitudes in-line with the conservation agenda, it is shown that this relationship is necessary for a local concern and stake in the natural environment. Those who have no or minimal interaction, such as many of the young women of Ntloko, have no opportunity to forge a relationship with it. Ihlathi may be known through narrative, but not personal experience, and as such no significant attachments can be formed, and thus concern for its conservation status is irrelevant. It is clear that if you remove people from an environment, you remove the stake they hold in the environment in question, thereby disrupting the relationship, and alienating people from nature. While a relational epistemology may not equate to conservation practices, it does imply a stake or concern in the environment, and as such, may provide an opportunity for conservationists to work with local communities. Resistance to conservation and development projects that aim to exclude local interaction, and therefore relationships, with the environment, will always be strong when local identities are intricately tied to the places and experiences that form them. Threatening that relationship threatens local identities and the attachments that orient them.

- Description: Research problem: Various factors which influence industrial relations climate can be classified as input variables (Dastmalchian, Adamason and Blyton, 1991). The industrial relations climate (IRC) in turn has the potential to positive or negatively influence and be influenced by the industrial relations outcomes of the organisation such as labour turnover, industrial action and productivity. Management therefore need to be aware of the prevailing IRC as well as the factors influencing the prevailing industrial relations climate so as to take the necessary and relevant measures and steps to improve the labour-management relations. Research objectives: The research objectives for addressing the research problem were mainly to ascertain the prevailing labour relations climate within the selected mine. The second objective was to identify the factors that shape labour relations climate and thirdly to establish the impact of the prevailing industrial relations climate within the mine Research questions: Research questions for the study were developed and were; What is the overall labour relations climate? What is the contribution of each of the five dimensions to the overall labour relations climate? What is the relationship between the subgroups, distinguished by union affiliation and occupational level? What is the relationship between the sub-groups, distinguished by gender, age, race years in organization, full-time or part-time, union affiliation, years in union, union status, occupational level, educational level and the five dimensions of the labour relations climate? What are the factors that shape the industrial relations climate with particular reference to the following factors such as the organisational context and background, the structure of the organisation, the Human Resources context, the Industrial Relations context and Industrial relations outcomes? Research design: The study was descriptive research and both qualitative and quantitative methods were used in order to address the objectives of the study. A self-administered survey questionnaire was used to collect quantitative data and in-depth semi-structured face-to-face interviews were also used to collect data relating to the IRC and the factors influencing the industrial relations climate. Human Resources records and reports were also used to provide secondary data for industrial relations outcomes. Major findings: The results from the study revealed that overall a negative IRC prevailed within the mine. This also applied to the five dimensions of climate that were measured. It was found that there was agreement between the unionised and the non-unionised employees’ perceptions of the industrial relations climate and similarly, when the miners’ perception of climate was compared with the more managerial group. The only really significant difference in perception was that management felt that the climate was fairer than did the miners. The results also revealed that the organisational environment and structure and the human resources and industrial relations contexts were consistent with the literature descriptions of an organisational environment that would inhibit a positive industrial relations climate. The results for the organisational outcomes, in particular absenteeism and turnover were also found to be consistent with those of organisations were the prevailing industrial relations climate was negative. The results also revealed that organisational age, size, ownership, structure, formalisation, decision-making, labour market, union-management consultation, communication were influenced and shaped the prevailing IRC. It also revealed that the prevailing IRC had impact on the levels of absenteeism and labour turnover.

- Description: The purpose of the study is to compare the dispute resolution systems of Uganda and South Africa. The historical developments of both systems were discussed so as to understand the factors that contributed to their growth or demise. From the study, it is clear to see that the Ugandan system’s development has been greatly affected with every regime change, between 1894 to the present. The developments that were tackled are closely related to various historical and political phases through which Uganda has passed and these significant periods are 1894- 1962 (pre-independence), 1962-1971 (Obote 1), 1971-1979 (Amin), 1980-1985 (Obote II), 1986- 2006 (NRM) and 2006 to the present Multi-party system. The South African system on the other hand is divided into four eras with the first one beginning from 1870 to 1948, the second era from 1948 to 1979, the third from 1979-1994 and the last era from 1994 to the present date. The South African system has been greatly influenced by the past government’s move to create a dual system of labour relations that was eventually removed. The two systems were compared using a framework created basing on literature by ILO (2013), Brand, Lotter, Mischke, & Steadman (1997) and Thompson (2010). The framework for comparison outlines the elements of a dispute resolution which include the nature of the dispute, coverage, processes, avenues and human resources. It further presents the criteria and possible indicators to evaluate the performance of the system which are legitimacy, efficiency, informality, affordability, accessibility, a full range of services, accountability and resources. The comparison highlighted the various differences between both countries. The study established differences in the nature of disputes as the Ugandan system does not differentiate between the different types of dispute unlike the South African system which differentiates them and has different avenues for their settlement, the fact that the South African system has a number of avenues to cater to the different types of disputes unlike the Ugandan system which only has one route beginning with the Labour officers and the Industrial court if unresolved. An evaluation of the performance of both systems brought to light the number of changes the Ugandan system has to undergo so as to meet the expectations of the International Labour Organisation and have an effective system. The South African system proves to be more legitimate, efficient, informal, affordable, and accessible than the Ugandan system. Further still the South African system provides a full range of services is more accountable and has enough resources when compared with the Ugandan system. Recommendations have been proposed at the end of the study, mainly for the Ugandan system as the South African system appears to be more advanced and more effective in dispute resolution by international standards. The recommendations suggested are creating an independent dispute resolution system, mass sensitisation on labour rights, accreditation of private agencies, create a separate dispute resolution system for the informal sector, proper routing of disputes, creation of an independent body to monitor the national system, encouraging the creation of more democratic workplaces, re-establish the industrial court and finally, employing and training more labour officers.

- Description: Research problem: The Port Elizabeth hospital complex is faced with many staff-related challenges including the difficulty of retaining staff. Factors such as salaries, work environment, work injury, work related stress, personal growth and development opportunities, advancement and promotion opportunities, relationships with supervisor(s), are among the issues that contribute and have been found to be some of the factors affecting employees’ perceptions and attitudes towards their work and ultimately to their intentions to stay or leave. Research objectives: To address the research problem, research objectives and questions were established. The main objective of the research was to investigate the perceptions and attitudes influencing the employees’ intention to quit their jobs within the hospital complex. The key perceptions and attitudes that were measured were; job satisfaction, perceived organisational support and organisational commitment. The secondary objective of the study was to determine, from a list of predetermined factors, which were related to job satisfaction, perceived organisational support and organisational commitment and the intention to quit. Research questions: Four research questions were established and these were: What are the employee perceptions and attitudes towards the organisation and their work in the organisation? In particular how satisfied are the employees with their jobs (job satisfaction), how committed are they to the organisation (organisational commitment), how do they perceive the support within the organisation (perceived organisational support) and do they intend to remain with the organisation (intention to quit measured as the intention to stay). What are the most important factors contributing to job satisfaction, perceived organisational support, organisational commitment and intention to quit? (Measured as the intention to stay). What is the relationship between the sub-groups, identified as gender, race, nationality, occupational level, age, hospital, and length of tenure and job satisfaction, perceived organisational support and organisational commitment? What is the relationship between the sub-groups, identified as gender, race, nationality, occupational level, age, hospital, and length of tenure and intention to quit (measured as the intention to stay)? Research design: The nature of this research was a descriptive study collecting quantitative data. A self-administered survey questionnaire was used to collect information regarding employee perceptions and attitudes towards various aspects of their working conditions, their perceptions and attitudes towards the organisation and their intention to remain with the organisation. Major findings: The result of the survey showed that organisational commitment and positive organizational support are practically significantly positively correlated with the intention to stay. However, it was discovered that job satisfaction was statistically significantly positively correlated to intention to stay. The nine factors that were measured were found to be antecedents for all the three constructs of job satisfaction, organizational commitment and perceived organizational support. However, the factors that were also correlated with the intention to stay were promotion opportunities, nature of the work, communication and leader-member exchange.

- Description: The research assessed the implementation of the Performance Management System (PMS) in the Malawian civil service using a change diagnostic model called ‘causal model of organisational performance change’ by Burke and Litwin (1992). The motivation for the research topic comes from a background of the Malawi Government’s goal of improving service delivery to the public. The government launched the performance management system as one of the change interventions that would assist in achieving its service provision goal. For the achievement of the service provision goals, the PMS had to be implemented effectively. Using an integrative approach, the research employed both qualitative and quantitative methods to obtain data that was structured around the organisational elements of the Burke-Litwin model. Using purposive sampling, 195 departments in the Malawian Civil Service formed the population from which the sample was drawn. Of the 195 departments, 69 departments, represented by an officer from each department, participated in the study. Three departments namely; The Office of the President and Cabinet (OPC), The Department of Human Resource Management and Development (DHRMD) and The Civil Service Commission (CSC) were included in the sample in addition to the 69 departments. These three departments were chosen due to their involvement in the formulation and implementation of the Performance Management System (PMS). Information from the three departments was obtained through interviews while questionnaires were administered to the remaining sample subjects. The research found that both the transformational and transactional factors were lacking in supporting the implementation of the PMS in Malawian civil service. Fundamental prerequisites like systems’ compatibility, assessment of enabling culture and amendments of relevant laws were not considered before the implementation of the system. Upon commencement of the implementation process the support from political leaders and donors declined and the evaluation process lacked inclusion of key stakeholders. The current research expands the application of the Burke-Litwin model in assessing the ‘post change intervention’ implementation processes. The findings could possibly provide valuable input in the form of the following recommendations: The government should consider working on the culture of the civil servants, the capacity of the implementing structure of PMS, the evaluation of the PMS and the prerequisites for the programme. The government should consider being inclusive when evaluating PMS and in assessing the performance of employees, and lastly, there is need to fully utilise technology and the functional position of stakeholders like the Civil Service Commission.

- Description: The study will investigate how the workers of Ekurhuleni Metropolitan Municipality in the Department of Roads and Stormwater (Eastern region) feel about their jobs in terms of job satisfaction. Furthermore, the study will investigate how they feel about commitment to the union, commitment to the organisation, and management satisfaction during and after the implementation of job task levels, which was the result of the wage curve agreement that was signed in 2010 and implemented in 2011.The first objective of the study is to describe the collective agreements that were signed in 2010 as a result of a need to categorise municipalities and evaluate jobs, and the consequences of the collective agreements on employees through the study of documents supplemented by interviews and questionnaires. The second objective is to investigate if there has been a change in attitudes of the employees in the Roads and Stormwater Department of the Ekurhuleni Metropolitan Municipality after the implementation of the wage curve agreement. There are six research questions; two relate to the first objective, and these are (a) what was the nature of the wage curve and job evaluation collective agreement? and(b) what were the consequences of the implementation of the wage curve and job evaluation collective agreement of the employees of the Ekurhuleni Metropolitan Municipality? The other four questions related to the second objective, which led to the following research questions related to the attitudes of the employees and the change in these attitudes after the implementation of the collective agreement. These four questions were (a) what was the change in employee attitudes post the introduction of the wage curve? in particular, the attitudes of organisational commitment, job satisfaction, management satisfaction and union commitment, (b) what is the relationship between the sub-groups and employee attitudes pre the wage curve agreement implementation?(c) what is the relationship between sub-groups and employee attitudes post the wage curve agreement implementation? (d) what is the relationship between the sub-groups and the change in employee attitudes pre and post the wage curve agreement implementation? Quantitative and qualitative research methods were used in the study to analyse the strike process and to understand and describe the attitudes of all the participants in relation to the four constructs provided by Chaulk and Brown (2008). Self-administered questionnaires will be given to participants, and there will be face-to-face interviews with the union officials and management. The findings relating to the first objective indicate that the employees were unhappy with the implementation of the wage curve collective agreement. The second objective showed that the changes in the attitudes of employees after the implementation of the job evaluation and wage curve collective agreement were negative and that there was a significant decrease in the level of organisational commitment, job satisfaction, union commitment and management satisfaction after the implementation.

- 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: 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 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.
