- Description: This study investigated the reduction reaction of ruthenium tetroxide by various aliphatic alcohols in acidic medium. UV-Vis spectroscopy still plays an essential role in the analysis and study of volatile ruthenium tetroxide and was used in this study to collect kinetic data. This data was analyzed using graphical and computational methods, such as Mauser diagrams and kinetic simulation software. From the results obtained it is proposed that the reaction occurs by the following two-step reaction model: Ru(VIII) k1 Ru(VI) Ru(VI) k2 k-2 Ru(III) Molar extinction coefficients and conditional rate constants were calculated using kinetic simulating software and a hydride transfer mechanism was proposed. The temperature dependence of this reduction reaction was also investigated and thermodynamic parameters calculated. Ruthenium concentrations were determined using a method employing UV-Vis spectroscopy. The method proved to be a reliable, sensitive and simple technique.

- Description: The key debates after apartheid have been on the successes and shortcomings of the social and economic policies that were adopted after apartheid. The ANC government decided to approach poverty reduction by closing the inequality gap between racial groups in the country. It planned to provide services that would improve the poor people’s lives and also create employment to sustain development. To provide the necessary services, the government formulated two broad, but linked macroeconomic policies namely: the RDP and GEAR which focused on the demand and supply side respectively (Venter and Landsberg (2006). This indicated the importance with which the people’s welfare and growth were regarded by the South African government. It indicated that the government believed in pro-poor growth. The purpose of this study was to gain better and deeper understanding about poverty reduction since the 1994 political transition, from the poor people of Airport Valley (in the Nelson Mandela Metropolital Municipality), who experience poverty from the real world. The study attempted to find out from these people if there was improvement in their lives since democratisation. This qualitative and quantitative study used three methods of collecting data namely: a questionnaire, interviews and observation. The results of the study suggest that there has been lack of commitment by RDP and GEAR, as the conditions under which the people live and therefore their standard of living have not improved. The study recommends that the government should speed up the process of service delivery at Airport Valley and also include the people in decision making about the future of Airport Valley.

- Description: This research study examined whether the physical resources in rural secondary schools are adequate and are managed properly by the school principals, for quality education to be achieved in the Eastern Cape Province. The dramatic changes in South Africa recognized that the future depends on an education system which develops the full potential of all learners. Although the Constitution of South Africa is advocating for equal education for all, there are disparities which are evident in the quality of the infrastructure, especially in remote rural areas where the fundamental requirements for effective education are lacking such as, water, electricity, sanitation and basic educational equipment. This shows that, although policy and legislative frameworks for transforming the education system have been put in place, managing the change is still a key challenge especially that of physical resources. Management of physical resources illustrates the problems facing principals by pointing to the lack of basic facilities in many rural secondary schools. In terms of the provision and management, many challenges remain, like most schools do not have adequate physical facilities. School buildings such as classrooms are inadequate or unsafe with no toilets, libraries, laboratories and many learners and teachers do not have learner teaching support materials (LTSMs). On the other hand, in terms of the Constitution, the Department of Education is responsible for bringing redress, equality and to upholding the Constitutional values such as shared decision-making, transparency, shared accountability and empowerment for equal partnership with other stakeholders. The physical resource management is one of the major responsibilities of principals. Their leadership is largely about ensuring that a clear and shared sense of direction is developed for both leadership and management. The school viii system meant that schools have moved nearer to the communities they serve and this has led to schools being more accountable to their communities. This study further investigated whether there is a significant correlation between the management of physical resources and quality education as well as the eradication of poverty in the rural secondary schools of the ECP. The proper execution of the management tasks of planning, organizing, leading, and controlling (POLC) by the principals have contributed extensively to the success of the schools. Therefore, this will mean that the act of managing physical resources through POLC and the process of working with or through SGBs, teachers, parents, learners, EDOs and the community at large to achieve set goals of education of relevance, excellence and quality education by effectively and efficiently using the physical resources in a school climate and environment that is collegial. The study showed that there is a link between management tasks (POLC) and collegial style of leadership in the school. The literature reviewed supported the view that the invitational style of leadership and collegiality increase the potential of a school to manage its physical resources economically, efficiently and effectively, particularly in a climate where the resource handlers take ownership of the school especially in remote rural settings. The 255 out of 300 subjects (85%) chosen to participate in this study were selected on the basis of their accessibility. Convenience sampling was used to conduct the study as this ensured that the population represented stakeholders that manage physical resources at schools, such as deputy principals, head of departments and teachers. Questionnaires were distributed, completed and collected personally. The questionnaires were analyzed and gaps such as the effects of lack of physical resources and how the learners’ profile were affected were reinforced by individual and group interviews that were semi-structured as ix well as participant observations from principals at O.R Tambo, Chris Hani and Amathole District Municipalities were conducted. It was deduced from the statistical data presented that there is a significant correlation between the principals’ management tasks and the quality of education. This shows that the more the principals blend properly planning, organizing, leading and control management tasks the more the physical resources will be managed better, that is, effectively, efficiently, economically and transparently and the less the bringing together of management tasks the less the meaningful management of physical resources will be. The study supported the hypothesis that a combination of management tasks performed by the principals positively influences the proper management of physical resources in rural secondary schools of ECP. The study rejects both null hypotheses that there is no significant correlation between planning, organising, leading and controlling as leadership functions of PRs and the quality of education in rural secondary schools of ECP as well as, that principals of rural secondary schools are not expected to possess adequate leadership knowledge and skills to effectively manage available PRs in their rural secondary schools. This study affirms the view that adequate physical resources are crucial as well as the appropriate management skills of principals for high quality education to be achieved in rural secondary schools. Without adequate physical resources, proper handling of the limited physical resources and the possession of management skills by principals, rural schools are less likely to succeed in their efforts to improve education.

- Description: This research engages with a contemporary theoretical debate in the literary field, namely the ability of fictional texts to contribute to archival records. Contemporary research in archival discourse suggests that there are many intersections between fiction and the archive. Using Hamilton and others’ seminal text Refiguring the Archive (2002) and Pasco’s “Literature as Historical Archive” (2004) as point of departure, this dissertation offers an analysis of the South African English translation of Marlene van Niekerk’s Agaat (2004, translated 2006). In both form and function, the novel is viewed as a simulation of an archive. In Agaat, Van Niekerk has compiled a fictional archive of two indigenous South African cultures through her portrayal of the two main characters: Afrikaner culture during apartheid as embedded in the focalization of Milla de Wet and remnants of Khoi and/or San culture as emerge from the fictionalised subjectivity of her coloured housekeeper-nurse, Agaat. Through a conceptual and theoretical exploration of archival discourse, I argue that literary texts, such as Van Niekerk’s novel, have the potential to refigure (or creatively redefine) the archive and to enhance its scope and relevance, especially as South Africa undergoes transformation.

- Description: The literature has indicated that nurses perceive more occupational stressors than do other professional groups. HIV is a new stressor which has impacted on society, in particular on people caring for HIV/AIDS patients. The availability of antiretroviral treatment (ART) which is accessible at wellness clinics has improved the quality of life of people with HIV and greatly prolonged the lives of many infected people. Wellness clinics are out-patient clinics where HIV positive patients receive their ART. This study has explored and described the occupational stressors perceived by nurses working in wellness clinics in Nelson Mandela Bay. The study was conducted using a qualitative research approach. Convenience sampling was used consisting of voluntary registered female nurses. The data were collected by means of semi-structured interviews. The interviews were audio-recorded and transcribed verbatim. The data were analyzed using Tech’s method. The nurses who participated in this study reported their perceptions of occupational stressors in wellness clinics where they worked. The occupational stressors perceived by the nurses included the working environment, interpersonal relationships and the organizational structure. However, they also reported that they experienced satisfaction from their jobs despite the perceived stressors.

- Description: The present study involves an exploration of the phenomenological expenence of posttraumatic growth in the context of a traumatic bereavement. An idiographic case study of a student who had witnessed her mother's death twelve years previously was conducted. Semi-structured interviews elicited data which was analysed using interpretative phenomenological analysis (IP A). Posttraumatic growth was found to have developed with regards to self-perception, relationships, and also in a broader spiritual and existential domain. The findings of this study shed light on the extant posttraumatic growth literature. In particular, findings were discussed in relation to the posttraumatic growth model as proposed by Calhoun and Tedeschi (2006). As posttraumatic growth is a relatively young concept, further research is needed in order to understand the meaning of reported growth more fully. While posttraumatic growth has been investigated in the context of bereavement, future research should distinguish more clearly between growth following traumatic and non-traumatic bereavement. Posttraumatic growth has received minimal empirical attention in South Africa, and therefore exploration of this area is suggested in the future. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Tabloid journalism has and continues to spark controversy. Scholarly considerations of tabloid journalism often question its contribution to democratic causes. However, little academic attention has been given to the question of how tabloids are understood and evaluated by their audiences. This study considered a range of audience responses to the Daily Sun by analysing the way some of its readers understand and evaluate it. The study examined the appeal of this popular tabloid to some Grahamstown readers. Reception analysis was employed to determine why these people read the Daily Sun. In particular, the active audience theory was used as a framework to conduct the research. To achieve the objectives of the study, qualitative research methods such as focus group interviews and individual in-depth interviews were employed. Looking at the findings, many of the respondents acknowledged they read the tabloid for interpersonal communication, diversion and entertainment. The results also revealed that their lived context plays a major role in their reading of stories. In a wider context, the research contributes to an understanding of the popularity of tabloid newspapers.

- Description: Privilege is an evidential principle which, on the grounds of public policy, excludes evidence relevant and otherwise admissible. This thesis aims to discover whether privilege should be applied to the psychotherapeutic profession in South Africa. At present, the only profession in South Africa afforded privilege is the legal profession. There are two main theoretical justifications for privilege: the utilitarian and the individual/human rights approach. This thesis considers whether the psychotherapeutic profession warrants privilege under either theory, and recommends that the law of privilege integrate both theories rather than adopt one or the other. The impact of the Constitution and the right to privacy receive particular attention. Very little literature or case law on the question of psychotherapeutic privilege was found in South Africa. Consequently, extensive comparative research into the common-law systems of England, Canada and United States of America was done. This research yielded some interesting findings. The first is that case-by-case development of the law of privilege is uncel1ain and fragmented. The next is that psychotherapeutic privilege exists in almost absolute form in the United States of America, but is littered with lacunae causing as much uncertainty as the case-by-case approach to privilege law. The most helpful method of dealing with the problem was found in Canada, where a two-stage approach to protecting personal information, including psychotherapeutic records, has been developed. In light of this research, this thesis reassesses the original viability of psychotherapeutic privilege in South Africa. Privilege, it was found, is not the best solution to protecting psychotherapeutic communications. This thesis recommends legislative adoption of an amended two-stage approach based on the Canadian model for sexual offence trials as the best method of protecting psychotherapeutic communications in both civil and criminal proceedings. The thesis ends by suggesting draft legislative provisions.

- Description: This study set out to explore the possibilities that the Critical Realist concept of a stratified ontology might have for environmental learning and materials development processes. This involved processes of ongoing contextual profiling; the use of picture-based resources and storytelling to support the engagement with the marine harvesting contexts of the villages of Hamburg and Ngqinisa, in the former Ciskei. At the heart of the study was the process of uncovering the empirical, the actual and the real in the context of a community of coastal marine harvesters whose lives and livelihoods are affected by poverty and a history of inequality, and more recently by issues such as HIV/AIDS. Their stories of existing practice changed as we engaged with picture-based narratives, gaining depth and focus in relation to sustainability issues. The learning processes associated with and emerging out of the research processes were enhanced through abductive use of metaphors and graphic illustrations, and through intra- and inter community exchanges, again using picture based narratives. As the study unfolded, the development of environmental education materials receded. Focus turned to how conceptual abstraction processes (of abduction (metaphor) and retroduction) and the stratified ontological framework allowed for learning across epistemological divides.

- Description: The abalone (Haliotis midae) culture industry in South Africa is becoming increasingly dependent on the use of formulated feeds, due to limitations in the supply of kelp. The bulk of the feeds that are currently available were developed based on the requirements of juvenile abalone cultured within the optimal temperature range for growth (18 - 20 °C). However, most abalone farming facilities are land-based pump ashore operations and are thus mostly exposed to temperatures outside of this range. In addition, these feeds have been found to be unsuitable for abalone cultured at elevated water temperatures (> 20°C). The aim of the study was to develop size and temperature specific diets for H midoe through optimisation of dietary protein, energy and lipid levels. Abalone were cultured under farm-like conditions in three partially recirculating temperature controlled systems at either 18, 22 or 24°C and fed formulated diets containing graded levels of protein (18,22 and 26 %) and energy (11.6, 13.5 and 16.2 MJ.kg·I ). Abalone were stocked into baskets at 5 % of available of surface area (n=36) and each diet (n=9) was fed to four baskets of abalone at each of the three temperature regimes for ten weeks. Abalone growth was temperature dependent, with growth declining from 4.33 g.month-I for abalone cultured at 18°C to 0.77 g.month-I at 24°C. Dietary protein could be reduced from 26 to 18 % provided dietary energy levels were maintained at 13.5 MJ.kg- l • A dietary energy level of 11.6 MJ.kg-1 was insufficient to meet the energetic requirements of H midae regardless of the protein content of the diet. The effects of water temperature and body size on the protein requirements of H midae were investigated by culturing abalone at temperatures within the optimal range for abalone farming (i.e. 14, 16 and 18°C). Three size classes of abalone (15, 50 and 80 mm) were fed formulated feed containing graded levels of dietary protein (20, 26, 32, 38 and 44 %) under controlled laboratory conditions for 12 weeks, and, in a separate experiment, under commercial farm conditions for 24 weeks. It was not possible to convincingly define the optimal protein levels for abalone of different sizes in this experiment because growth rates fell below average commercial growth rates obtained on farms. Growth was temperature dependent in the laboratory trial, with the rate of weight gain of the 15 mm (ANOV A: p=0.002) and 50 mm abalone (ANOV A: p=0.02) increasing significantly with an increase in temperature from 14 to 18°C. In the farm trial, dietary protein content did not affect the growth rate of the 10-15 or 80 mm abalone (ANOVA: p>0.05), however, the 50 mm abalone displayed significantly higher weight gain on the 32 % (4.72±0.20 g.month-I ) and 38 % (5.01±0.34 g.month-I ) protein diets compared to those fed the 20 % protein diet (3.75±0.13 g.month-I ) (ANOVA: p=O.OI). Although definition of optimal dietary protein levels were not possible, the effects of dietary protein content and water temperature on the growth of H midae were independent signifying that the protein requirements of abalone are temperature independent. In addition, there was no evidence to indicate that abalone of the different sizes tested here had different dietary protein requirements. The size specific dietary lipid and protein requirements of H midae were investigated by feeding two size classes of abalone (30 and 60 mm initial shell length) diets containing graded levels of dietary lipid (4, 7, 10, 13 and 16 %) and protein (34 - 39 %) for 12 weeks. The 30 and 60 mm abalone were stocked at 7 (n=200) and 9 % (n=36) of the available basket surface area respectively and each diet was fed to four baskets of abalone of each size class. The protein requirements of H. midae are influenced by the amount of available dietary energy and thus it is possible that the ability of abalone to utilise lipids as a source of energy differs in the presence of varying levels of dietary protein. High levels of dietary lipid negatively affected the growth, condition factor and soft tissue glycogen content of both size classes of abalone. This negative effect was greater in the 30 mm size class compared to the 60 mm abalone. The corresponding increase in feed consumption and feed conversion ratio in response to increasing levels of dietary protein also provides evidence that abalone are unable to utilise dietary lipids as an energy source and high levels of dietary lipid probably inhibit the uptake of carbohydrates and protein. High dietary lipid levels did however appear to promote gonad maturation. It was possible to reduce dietary protein from 34 to 20 % without negatively affecting growth through the maintenance of dietary energy levels and thus it is recommended that future experiments on the energy content of formulated feeds should focus on the improved use of carbohydrates. Reductions in the protein portion of formulated feeds for H. midae are possible provided the diet contains sufficient levels of energy supplied from carbohydrates. As the ability of abalone to utilise dietary lipid is limited, lipids are unlikely to play a significant role as an energy source in abalone feeds. Further investigations should focus on the utilisation of various carbohydrate sources in abalone feeds.

- Description: Spectrophotometric techniques were used to elucidate the discrepancies surrounding the reduction of osmium tetroxide by several primary alcohols in a hydroxide matrix. In contrast to the documented literature, this reaction was observed to occur in two consecutive reaction steps. Geometrical and computational analysis of kinetic data revealed that the reaction proceeds by the following reaction model: Os(VIII) + RCH2OH Os(VI) + RCHO Os(VIII) + Os(VI) Os2(VII) k1 k+2 k-2 The conditional rate constants and molar extinction coefficients were calculated using custom written software. A hydride transfer mechanism, coupled with the synchronous removal of the hydroxyl proton of the alcohol, was postulated. The complexation between osmium(VIII) and osmium(VI) was investigated. Mole ratio titrations and mole fraction plots show that at pH 14.3 a 1:1 complexation occurs between osmium(VIII) and osmium(VI). The equilibrium constants and molar extinction coefficients calculated by these methods were found to be consistent with the parameters obtained from the reduction of osmium tetroxide by primary alcohols at pH 14.3. The formation of a mixed oxidation state dimeric osmium complex (denoted Os2(VII)) has been proposed. Key words: Spectrophotometric techniques, osmium tetroxide, osmium(VIII), primary alcohols, osmium(VI).

- Description: Ruthenium (II) polypyridine complexes in general have been extensively studied because of their unique redox and photochemical properties. A typical example of such complexes is tris(2,2’-bipyridyl) ruthenium (II). In this study, this complex was synthesized and then characterized using electronic spectroscopy and cyclic voltammetry. It was also shown that the ruthenium concentration could be accurately determined using ICP-MS. It was found that the complex is very stable in various chemical environments. It was observed from spectrophotometric investigations that persulphate and lead dioxide easily oxidize Ru(bpy)3 2+ to Ru(bpy)3 3+ in the presence of heat and H2SO4, respectively. It was also observed that the oxidation between Ru(bpy)3 2+ and cerium (IV) occurred at approximately 3:2 [Ce(IV)]/[Ru(II)] mole ratio. The resultant Ru(bpy)3 3+ solution was unstable in the presence of light and recovery of Ru(bpy)3 2+ occurred gradually. The regeneration of Ru(bpy)3 2+ from Ru(bpy)3 3+ was found to be a multistep process, which appears to involve the formation of an intermediate species. The following reaction model was found to best explain the kinetic data obtained: Ru(bpy)3 2+ + Ce(IV) → Ru(bpy)3 3+ Ru(bpy)3 3+ → Ru(bpy)3 2+ Ru(bpy)3 3+ → Ru* intermediate Ru* intermediate → Ru(bpy)3 2+ Theoretical rate constants were also calculated for the same process under the experimental conditions. The comparison between the experimental and theoretical results gave good agreement. In addition, the factors that influence the rate of the regeneration of Ru(bpy)3 2+ from Ru(bpy)3 3+ were also discussed.

- Description: It is widely assumed that the managers of companies behave in a self-interested and opportunistic manner when making the discretionary accounting choices that are applied in the preparation of published financial reports. Empirical research has found evidence for this in the United States, Britain, Spain, France and Australia, amongst other countries. There has, however, been no prior work of a similar nature in a South African context. The purpose of this study is to extend this body of work by examining the relationship between a number of potentially opportunistic (profit-increasing, income-smoothing and solvencyimproving) accounting choices made by the managers of South African listed companies, and growth rates in the share prices of those companies. Data in respect of thirty-nine medium-sized South African listed companies are analysed for evidence of the expected positive relationship between opportunistic accounting choices and share price growth. No evidence is found for this relationship. This may be due to limitations in the research design, inadequacies in the interpretation of the agency theory from which the hypotheses are developed, or a combination of both. Refinements in the research design or a re-interpretation of the theory may be successful in addressing these matters as part of future research efforts.

- Description: Common law does recognise the concept of dismissal based on operational requirements. It recognises dismissals that are based on breach of expressed or implied terms of contract of employment. The concept of operational requirements has its roots in the Labour Relations Act 28 of 1956. This Act recognised termination of employment of a number of employees due to ability, capacity, productivity, conduct and operational requirements and needs of undertaking industry trade or occupation of the employer as legitimate. Under the 1956 LRA, employers were allowed to dismiss employees if employees refused to accept the proposed change to conditions of employment. The dismissal is called lock-out dismissal. This kind of dismissal entitled employers to dismiss employees on condition that the dismissal was temporary and the workers would be re-employed when they agree to the demands of the employer. After the contract of employment was terminated between the employer and employees, the employer was allowed to implement the changes using scab labour. The 1995 Labour Relations Act introduced section 187(1)(c) that was intended to re-enforce the abolishing of the lock-out dismissal. This section strictly forbids the dismissal of employees in order to compel them to accept demands of the employer in matters of mutual interest. Such dismissals are regarded as automatically unfair. In terms of section 64(4) of the 1995 LRA employers are not permitted to unilaterally effect changes to employees’ terms and conditions of employment. They are required to seek and obtain consent of the affected employees. If employees refuse to accept the proposed changes, the employer can use lock-out as defence. Firstly, the employer can initiate lock-out until employees accede to its demand. Secondly, the employer can lock-out employees in response to the notice of strike or strike of the employees. The employer can use scab labour during this lock-out period. Unlike the lock-out dismissal, lock-out under the 1995 LRA does not include termination of contract of employment. iv In contrast, employers are allowed to dismiss employees who refuse to agree to change to their terms and conditions of employment on the ground of operational requirements provided a fair procedure is followed. This reason for dismissal is not viewed by the courts as a dismissal to induce employees to accept the demand of the employer. The question that this study seeks to examine is the relationship between automatic unfair dismissal in terms of section 187(1)(c) of the Labour Relations Act and dismissal for operational requirements. A dispute between the employer and employees regarding change to terms and conditions of employment is a mutual interest dispute; and it therefore falls under collective bargaining. The same dispute can easily fall to rights dispute, because the reason for the proposed change to the production system and demand to the pursuit of improved efficiency and better achievement of profit objective related to operational requirement. There is obvious overlap between operational requirements and wage work bargaining. In Schoeman v Samsung Electronics, the court held that the employer is entitled to run its business in a prosperous way and this may entail affecting changes to terms and conditions of employment when the market forces demand so. In Mwasa v Independent Newspapers, the court held that change to terms and conditions of service of an employee can be proposed as a way to avoid retrenchment; dismissal of employees for refusing to accept the change is not covered by section 187(1)(c). In Fry’s Metals v Numsa, the court has rejected the notion that there is tension between section 187(1)(c) and section 188(1)(a)(ii). The court held that section 186(1) refers to dismissal or termination of workforce with the intention to end the employment contract and replacing the workforce with employees that are prepared to accept terms and conditions of employment that suit the employer’s operational requirements. The court argued further that the meaning of dismissal should be a v starting point when one wants to dispute the two sections. On the other hand, section 187(1)(c) was effected with a certain purpose, which is to prohibit the employer from dismissing employees in order to compel them to accept its demand in dispute of mutual interest. The court held that the dismissal in this case was final. The employer dismissed its employees because it did not need them anymore. This dismissal is in accordance with section 186(1). The court rejected that operational requirements is confirmed to saving business from bankruptcy. The court argued that the principle includes measures calculated to increase efficiency and profitability. The employer can dismiss and make more profit.

- Description: Common law does recognise the concept of dismissal based on operational requirements. It recognises dismissals that are based on breach of expressed or implied terms of contract of employment. The concept of operational requirements has its roots in the Labour Relations Act 28 of 1956. This Act recognised termination of employment of a number of employees due to ability, capacity, productivity, conduct and operational requirements and needs of undertaking industry trade or occupation of the employer as legitimate. Under the 1956 LRA, employers were allowed to dismiss employees if employees refused to accept the proposed change to conditions of employment. The dismissal is called lock-out dismissal. This kind of dismissal entitled employers to dismiss employees on condition that the dismissal was temporary and the workers would be re-employed when they agree to the demands of the employer. After the contract of employment was terminated between the employer and employees, the employer was allowed to implement the changes using scab labour. The 1995 Labour Relations Act introduced section 187(1)(c) that was intended to re-enforce the abolishing of the lock-out dismissal. This section strictly forbids the dismissal of employees in order to compel them to accept demands of the employer in matters of mutual interest. Such dismissals are regarded as automatically unfair.

- Description: The Electricity Distribution Industry (EDI) in South Africa is in the process of restructuring into six Regional Electricity Distributors (REDs). This would entail the merging of the national electricity utility, Eskom Distribution with municipalities to consolidate skills and to improve on efficiencies. This integration would involve the assimilation of not only physical assets but also various organisational cultures into a separate organisation responsible for supplying electricity services within its designated geographical area. A separate challenge facing Eskom is an intensive capital expansion program to increase generation capacity which will require a committed workforce to execute. Organisational culture has been regarded as leading to greater productivity and generating commitment to the values and philosophies of the organisation. The purpose of the research was to determine whether there was a significant relationship between the organisational culture, organisational commitment and employee performance in Eskom Southern Region. In order to achieve this purpose a survey was undertaken (N=83) which measured perceptions regarding the existing organisational culture, preferred organisational culture as well as organisational commitment. Performance rating scores were linked to each respondent and were obtained from the performance management process of Eskom Southern Region. The main findings of this research can be summarised as follows: • The dominant existing organisational culture in Eskom Southern Region is the power culture, while the dominant preferred organisational culture is the achievement culture. • There is a significant organisational culture gap between the existing and the preferred organisational culture in Eskom Southern Region. • The dominant organisational commitment within Eskom Southern Region is affective commitment together with normative commitment. • The findings related to the employee performance include: o A slight but significant negative relationship was measured between the existing achievement culture and employee performance. o No significant relationships were measured between the preferred cultures and employee performance. o No significant relationships were measured between the organisational commitment scales and employee performance. • The findings pertaining to the relationship between organisational culture and organisational commitment can be stated as follows: o A significant positive linear relationship between the existing achievement culture and affective commitment was measured. A strong, significant negative linear relationship between the existing power culture and the affective commitment was also measured. o No significant relationships were measured between the preferred organisational cultures and organisational commitment. o The organisational culture gap has a significant effect on the organisational commitment of employees. • The findings pertaining to the relationship between the biographical variables and the organisational culture, organisational commitment and employee performance can be stated as follows: o There exists a strong significant relationship between the years of service and the existing organisational culture scales. o No significant relationships exist between the preferred organisational culture scales and any of the biographical variables. There was a common agreement across all respondents on the preferred organisational culture. o A significant relationship was found between organisational commitment and the number of people supervised. o A slight but significant positive linear relationship between the age of respondents and employee performance ratings was measured. It can therefore be concluded that the type of organisational culture has a significant impact on the level of affective commitment of the employees within Eskom Southern Region. No significant positive relationship was found between organisational commitment and organisational performance in Eskom Southern Region.

- Description: This research investigates the relationship between innovation and leadership in First National Bank in South Africa. In an information age paradigm, innovation is a key driver of organisational success. Innovation allows an information age company to create a sustainable competitive advantage over its competitors. First National Bank (FNB) has recognised the need for innovation and measures the amount of innovation generated in each business unit on an annual basis. Leadership is a key factor influencing innovation in large, multi-segment organisations, particularly transformational leadership. Large multi-segment organisations often have multi-functional teams and transformational leadership of these teams more effectively promotes innovation. Large multi-segment organisations also often have complex decision making processes. Transformational leadership ensures optimal innovative decisions rather than adequate decisions are reached. FNB is a multi-segment organisation comprising ten business units each headed by a Chief Executive Officer (CEO). The relationship between the level of innovation being generated annually by each business unit and the leadership style of the business unit CEO formed the focus of this research. The Multifactor Leadership Questionnaire was used to gather information on the leadership style of each CEO's. Data on the level of innovation within each of these business units was supplied by First National Bank. Data was statistically analysed against the innovation generated by each business unit using correlation analysis. Most of the results testing the relationship between transformational and transactional leadership and innovation were found not to be significant. This contradicts the theory which suggests a positive relationship between transformational leadership and innovation.

- Description: Contemporary human resources management suggests that organisations which have been able to make it in the business arena have done so through good people management practices. Job satisfaction, through a people centered approach, has not been spared as one of the critical forces used in achieving organisational effectiveness. Traditional thought behind job satisfaction prescribes that satisfied employees tend to be more productive, creative and committed to their jobs; all of which are imperative to ii achieving an organisation’s bottom line. There has been some controversy surrounding the nature of the relationship between job satisfaction and organisational citizenship behaviour, which is another factor that is regarded as important in achieving organisational effectiveness. Some studies have shown that organisational citizenship behavior is a result of job satisfaction. In this regard, the present study focuses on the extent to which job satisfaction influences organisational citizenship behaviour among selected organizations in Zimbabwe. The study hypothesised that job satisfaction correlates positively with organisational citizenship behaviour. Participants in the study comprise of middle level management, supervisors and lower level employees. Two questionnaires were combined to collect data for the study. The Minnesota Satisfaction questionnaire was used to collect data on job satisfaction whilst a questionnaire by Konovsky and Organ (1996:253) was used to collect data on organisational citizenship behaviour. The results show that employees in the organisations surveyed report moderate levels of job satisfaction and organizational citizenship behavior. It was established that there was a substantive correlation between job satisfaction and organisational citizenship behaviour.
