- Description: There is a common perception that media depiction of mental health and illness is overwhelmingly negative and inaccurate. Media portrayal of mental illness is also viewed as an important element in forming and influencing society’s attitudes towards mental health issues, although there is no causal link to prove this. People with mental illness are most commonly shown as being violent and aggressive. Movie stereotypes that contribute to the stigmatisation of mentally ill persons include the mental patient as rebellious free spirit, homicidal maniac, seductress, enlightened member of society, narcissistic parasite, and zoo specimen. The profession of psychiatry is, has always been, and will likely continue to be a much enjoyed subject among filmmakers and their audiences, as it tends to provide exciting and emotionally compelling opportunities to portray personal struggles feared by most of humanity. This research will analyse the entertainment media in an attempt to provide evidence to support the above statement. The research will, furthermore, analyse the manner in which entertainment media represent the mentally ill with reference to popular films invariably produced in the US

An investigation into the synergistic association between the major Clostridium cellulovorans cellulosomal endoglucanase and two hemicellulases on plant cell wall degradation

- Description: The cellulosome is a multimeric enzyme complex that has the ability to metabolise a wide variety of carbonaceous compounds. Cellulosomal composition may vary according to the microbe’s nutritional requirement and allows for the anaerobic degradation of complex substrates. The complex substrates of interest in this research study were sugarcane bagasse and pineapple fibre waste, as they represent two important lignocellulosic, South African agricultural crops. The effective degradation of complex plant biomass wastes may present a valuable source of renewable compounds for the production of a variety of biofuels, for example bioethanol, and a variety of biocomposites of industrial importance. The identification of renewable energy sources for the production of biofuels is becoming increasingly important, as a result of the rapid depletion of the fossil fuels that are traditionally used as energy sources. An effective means of completely degrading lignocellulose biomass still remains elusive due to the complex heterogeneity of the substrate structure, and the fact that the effective degradation of the substrate requires a consortium of enzymes. The cellulosome not only provides a variety of enzymes with varying specificities, but also promote a close proximity between the catalytic components (enzymes). The close proximity between the enzymes promotes the synergistic degradation of complex plant biomass for the production of valuable energy products. Previous synergy studies have focused predominantly on the synergistic associations between cellulases; however, the synergy between hemicellulases has occasionally been documented. This research project established the synergistic associations between two Clostridium cellulovorans hemicellulases that may be incorporated into the cellulosome and a cellulosomal endoglucanase that is conserved in all cellulosomes. This research study indicated that there was indeed a synergistic degradation of the complex plant biomass (sugarcane bagasse and pineapple fibre). The degrees of synergy and the ratio of the enzymes varied between the two complex substrates. The initial degradation of the bagasse required the presence of all the enzymes and proceeded at an enhanced rate under sulphidogenic conditions; however, there was a low production of fermentable sugars. The low quantity of fermentable sugars produced by the degradation of the bagasse may be related to the chemical composition of the substrate. The sugarcane contains a high percentage of lignin forming a protective layer around the holocellulose, thus the glycosidic bonds are shielded extensively from enzymatic attack. In comparison, the initial degradation of the pineapple fibre required the action of hemicellulases, and proceeded at an enhanced rate under sulphidogenic conditions. The initial degradation of the pineapple fibre produced a substantially larger quantity of fermentable sugars in comparison to the bagasse. The higher production of fermentable sugars from the degradation of the pineapple fibre may be explained by the fact that this substrate may have a lower percentage of lignin than the bagasse, thus allowing a larger percentage of the glycosidic bonds to be exposed to enzymatic attack. The data obtained also indicated that the glycosidic bonds from the hemicellulosic components of the pineapple fibre shielded the glycosidic bonds of the cellulose component. The identification of the chemical components of the different substrates may allow for the initial development of an ideal enzyme complex (designer cellulosome) with enzymes in an ideal ratio with optimal synergy that will effectively degrade the complex plant biomass substrate.

- Description: Software programs designed to calculate the tax liability of individuals and other types of tax entity are being designed and used with increasing frequency. Research done in the United States of America appears to indicate that these programs do not achieve any saving in time and, in fact, may take longer to use than to complete a tax return by hand. As the South African revenue collection system appears to be moving closer to a self-assessment system, where the calculation of tax owing will be the responsibility of the taxpayer, the research essay sets out to determine whether there is a saving in time when calculating a tax liability using a tax software program, instead of calculating it by hand. In addition, the research aims to determine how much time, on average, is saved or lost, using such a program, and whether there is any correlation between the time taken to perform a calculation by hand and that using the software program. It does so by comparing the average estimated time it would take to complete tax calculations for individuals by hand with the average time taken to complete the same tax calculations using a tax software program. The average time taken to do the calculations by hand is based on the time allocation given for questions by the authors of a published question bank for university students. The time taken using software is determined by using a stop-watch to time each question being processed. The results, subject to assumptions made in carrying out the research, show that there is a substantial saving in time using the software program. Based on the data, however, the results indicate a weak correlation between the estimated time taken to do a calculation by hand and the estimated time using the software program. Possible reasons for the weak correlation are discussed. A recommendation is also made for the standardization and certification of existing tax calculation software.

- Description: The use of whistle-blowing as means to curb unethical behaviour of police officers in the Nelson Mandela Bay is investigated in this study. In order to investigate this, various instruments were used, these are interviews and questionnaires. However the objectives of the study were: - To examine the implementation of whistle-blowing in the SAPS. - To develop strategies and measures that can be used to encourage whistle-blowing in the SAPS. Broadly speaking, these objectives have been achieved by providing empirical evidence which shows that: - Unethical behaviour by police officers is the most ethical challenge facing police officers in the Nelson Mandela Bay Area. This is based on the findings which eminate from the interviews. - Whistle-blowing is used by police officers as an early warning system that alerts the superiors about misconduct before it is too late as it defects and deters wrongdoing. However, the study suggests various strategies and measures to assist the implementation of whistle-blowing. These strategies include: - Development of hotlines. - Assurance of confidentiality and anonymity of disclosures. - Response plan development. - Training development. - Regarding whistle-blowing as an ongoing communication. This study also indicates that misconduct by police officers in the Nelson Mandela Bay area is not high. While whistle-blowing is considered as a key tool in promoting individual responsibility and accountability among police officers. In conclusion, recommendations are provided which could assist the SAPS and individual police officers to improve ethical conduct, and for improved measures and mechanisms to deal with unethical behaviour of police officers and recommendations for improved implementation of whistle-blowing process.

- Description: This research entails a case study on the investigation of illegal farm evictions in the Great Kei Local Municipality of the Eastern Cape. The study was propelled by the plight of people living and working on farms in South Africa who are always victims of illegal farm evictions. Such evictions in many an instance violate their basic human rights protected by South Africa’s constitution and many other international conventions. It is hoped that the findings and recommendations of the research will have a profound impact on how illegal farm evictions in future will be handled by those championing the rights of people living and working on farms. Similarly, there is hope that this study will create an interest in others to new broader issues of human rights protection. A closer look at concepts like constructive evictions is necessary because of their traumatic nature to their victims. The study is divided into five chapters. 1. Introduction This chapter provides a background, the purpose of the study, specific objectives or research questions, hypotheses or assumptions of the study, the significance of the study, justification or rationale of the study, delimitation of the study, literature review, methodology, ethical considerations, and the limitations of the study. 2. The history of farm evictions in South Africa This chapter gives an outline of farm evictions in South Africa from both the colonial and apartheid 3. The culture of human rights in South Africa This chapter examines the institutions and instruments that influence the human rights culture in South Africa. It focuses on the legislative framework of human rights. 4. Farm evictions in the Great Kei Local Municipality of the Eastern Cape This chapter discusses farm evictions in the Great Kei Local Municipality and South Africa in general between December 2001 and December 2006. A case study of the same municipality is the nucleus of this research. 5. Conclusion The evaluation, findings, and recommendations of the study form the greater part of the chapter.

An investigation of masculinity in J. M. Coetzee's disgrace (1999)

- Description: The study of Masculinity is a fairly new phenomenon which developed as a refinement of gender studies. The theoretical frameworks on masculinity are still under development and are often severely contested. This study proposes to examine the dynamics of masculinity studies, critiquing the notion of ‘masculinity in crisis’. The premise of the masculinity in crisis debate is that men are experiencing an increasing sense of powerlessness. This dissertation aims to examine the masculine identities represented in Disgrace and to test whether they are better understood through the lens of masculine theory. The disgraceful situation of David Lurie is arguably not merely a result of hapless circumstance, but rather illustrates significant parallels with the crisis debate. The basic premise of this debate is that the behaviour previously condoned and applauded as healthy 'manliness' is now being labelled as anti-social and destructive. It is not just masculine roles that are under threat. Other forces behind the crisis are “the loss of masculine rights and changes in the pattern of employment” (Beynon 2002:75). One view held by theorists of masculinity studies is that for real change to occur, a fluid definition of masculine identity is needed. In J.M. Coetzee’s Disgrace (1999), the main protagonist is David Lurie. He may arguably be said to typify a masculinity that is in a state of crisis because of his stoic refusal throughout the novel to change or reform: “I was offered a compromise, which I would not accept”, he says, and: “Re-education. Reformation of the character. The code word was counselling” (1999:66). His aversion to such counselling and refusal to compromise mark his resistance to change.

- Description: Significant changes have taken place in recent years in leadership theory and practice world wide. Theorizations of effective leadership have evolved from being authoritarian and task-centered to a model in which leaders are encouraged to look beyond their self-interest and prioritize the interests of the group. This study investigates the development of an alternative form of leadership through community building in two male school boarding houses. It attempts to ascertain whether students are able to work collaboratively towards developing an environment conducive to servant leadership. Structured according to the transformative research paradigm, this action research study was conducted in an independent school, Kingswood College, in Grahamstown, South Africa. The College is a traditional independent co-educational school that prides itself on producing leaders. As the school was in the process of reviewing its leadership system, it became an appropriate site to investigate the development of community and to explore possibilities for the emergence of an alternative form of leadership that would reflect the attributes of servant leadership. The participants in the study were volunteers from two boarding houses, who agreed to reflect on their perceptions and experiences of the way in which their houses functioned. My research findings show that through their willingness to engage in moral dialogue, students can transform their boarding houses into closely-knit communities bound together by shared values and beliefs. Closer relationships make for better understanding. As the leaders take on the responsibility of caring for their juniors, a moral obligation begins to manifest itself. Leaders will display the attributes of servant leadership if they are prepared to acknowledge in practice this moral obligation to serve others.

- Description: Prevention of the accumulation of undesirable biological material i.e. biofouling upon a solid surface requires the use of antifouling systems. The solid surface may be a contact lens, an off shore oil rig or a living organism. When chemicals are employed as a mechanism of defense against biofouling, the agents involved are known as antifouling agents. Marine algae must protect themselves from fouling organisms and it is thought that one of the mechanisms used by these organisms is the production of secondary metabolites with an array of biological activities. In vitro studies have shown numerous compounds isolated from marine algae to possess antibacterial, antifungal and antimacrofouling activity. The aim of this study was to evaluate the secondary metabolite extracts of selected Southern African marine macro-algae as a potential source of compounds that inhibit biofilm formation and that could be used as antifouling agents. In this project, marine macro-algae were collected from various sites along the South African coastline. Their extracts were screened for antimicrobial activity against four ubiquitous microorganisms, Staphylococcus aureus, Klebsiella pneumoniae, Mycobacterium aurm and Candida albicans. Results of screening assays guided the fractionation of two Rhodophyta, Plocamium corallorhiza and Laurencia flexuosa. The algae were fractionated using silica gel column chromatography and compounds were isolated by semi-preparative normal phase HPLC. Compound characterization was performed using UV, IR and advanced one- and two-dimensional NMR (¹H, ¹³C NMR, COSY, HSQC, HMBC and NOESY) spectroscopy and mass spectrometry. Ten halogenated monoterpenes including four members of the small class of halogenated monoterpene aldehydes were isolated from extracts of P. corallorhiza. The compounds isolated included the known compounds 3,4,6,7-tetrachloro-3,7-dimethyl-1-octene; 4,6-dibromo-1, 1-dichloro-3,7 -dimethyl-2E,7 octadiene; 4,8-d ibromo-1,1,7 -trichloro-3, 7-dimethyl-2,5Eoctadiene;1 ,4,8-tribromo-3, 7 -dichloro-3,7-dimethyl-1 E,5E-octadiene; 8-bremo-6, 7-dichloro-3,7-dimethyl-octa-2E,4E-dienal; 4-Bromo-8-chloro-3,7-dimethyl-octa-2E,6E-dienal; 4,6- Dibromo-3,7-dimethyl-octa-2E,7-dienal; 2,4-dichloro-1-(2-chlorovinyl)-1-methyl-5-methylidene-cyclohexane and two new metabolites 4,8-chloro-3,7-dimethyl-2Z,4,6Z-octatrien-1-al and Compound 3.47. Methodology was developed for the chemical derivatization and mass spectrometric analysis of the aldehydic compounds, The aldehyde trapping reagent 0-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride was used to derivatize the molecules, stabilizing them and allowing for their complete characterization. From Laurencia flexuosa a new cuparene sesquiterpene 4-bremo-2-(5-hydroxy-1,2,2- trimethylcyclopent-3-enyl)-5-methylphenol was isolated along with two geometric isomers of the vinyl acetylene bromofucin , An halogenated monoterpene 3S*,4R*-1-bromo-3,4,8-trichloro-9-dichloromethyl-1-E,5-E,7-Z-octatriene was also isolated but was suspected to be a contaminant and an investigation into its biological source revealed that it originated from Plocamium suhrii. A third alga, Martensia elegans was extracted based on published reports of antimicrobial compounds in related species. A new a-alkyl malate derivative was isolated and characterized. Selected compounds isolated during the course of the study were employed in preliminary assays that tested their ability to inhibit biofilm formation by Pseudomonas aeruginosa. The halogenated monoterpenes isolated from the Plocamium species were the only active compounds. 3S*,4R*-1-bromo-3,4,S-trichloro-g-dichloromethyl-1-E,5-E,7-octatriene from P. suhrii inhibited biofilm formation through antibacterial activity on planktonic cells but could not prevent biofilm formation when employed as a film on the surface of microtitre plate wells. 1,4,8-tribromo-3,7-dichloro-3,7-dimethyl-1E,5E-octadiene and 4,6-dibromo-1,1-dichloro-3,7-dimethyl-2E,7-octadiene inhibited biofilm formation when applied as a film to the microtitre plate wells but had no significant antibacterial activity. No potential antifouling agents were identified in this project but the antimicrobial activity exhibited by the crude algal extracts was highly encouraging and a number of new research areas have been identified. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Prevention of the accumulation of undesirable biological material i.e. biofouling upon a solid surface requires the use of antifouling systems. The solid surface may be a contact lens, an off shore oil rig or a living organism. When chemicals are employed as a mechanism of defense against biofouling, the agents involved are known as antifouling agents. Marine algae must protect themselves from fouling organisms and it is thought that one of the mechanisms used by these organisms is the production of secondary metabolites with an array of biological activities. In vitro studies have shown numerous compounds isolated from marine algae to possess antibacterial, antifungal and antimacrofouling activity. The aim of this study was to evaluate the secondary metabolite extracts of selected Southern African marine macro-algae as a potential source of compounds that inhibit biofilm formation and that could be used as antifouling agents. In this project, marine macro-algae were collected from various sites along the South African coastline. Their extracts were screened for antimicrobial activity against four ubiquitous microorganisms, Staphylococcus aureus, Klebsiella pneumoniae, Mycobacterium aurm and Candida albicans. Results of screening assays guided the fractionation of two Rhodophyta, Plocamium corallorhiza and Laurencia flexuosa. The algae were fractionated using silica gel column chromatography and compounds were isolated by semi-preparative normal phase HPLC. Compound characterization was performed using UV, IR and advanced one- and two-dimensional NMR (¹H, ¹³C NMR, COSY, HSQC, HMBC and NOESY) spectroscopy and mass spectrometry. Ten halogenated monoterpenes including four members of the small class of halogenated monoterpene aldehydes were isolated from extracts of P. corallorhiza.

- Description: Researchers hold numerous perceptions of the educational aspirations and future career choices of teenage girls. Studies argue that factors such as the curriculum, teachers' and parents' attitudes, the impact of HIV/AIDS, and teenage pregnancy, influence girls' future educational and occupational hopes and dreams either positively or negatively. Other researchers claim that learners' career choice is limited by their potential and school performance. The existing literature also suggests that girls have lower self-esteem and levels of achievement than boys. This research seeks to gain insight into high school girls' perceived academic and vocational prospects. The research was carried out in an interpretive paradigm. Six secondary school female learners from one school participated in the study. Semistructured interviews were the core method of data collection, supplemented by questionnaires and a focus group interview. As teenagers, the girls were expected to already have started to think about their future hopes and dreams. The findings revealed that all the girls seemed to experience school as a place where they could acquire knowledge about what they needed to make them autonomous and successful in adult life. For them, their parents remained their major significant others. They regarded fear of poverty as a major factor motivating them to achieve their educational and vocational aspirations. Peer pressure appeared not to be a major determinant of these girls' successes in school. The girls believed that there is a relationship between their academic performance and their future vocational choice. In addition, the girls did not see boys as a threat to their climbing the ladder of success.

- Description: This study focuses on the implementation of a thematic approach in the Namibian Lower Primary Phase of schooling. The purpose of the study is to investigate teachers’ perceptions and understanding of the thematic approach and also to explore how teachers plan and implement a thematic approach in their classrooms. It is argued that a thematic approach allows for a combination of subjects that integrate content across the curriculum in such a way that learners can see the relations among concepts and so build up their knowledge in a more meaningful way. The work was done in a qualitative paradigm using a case study approach. Findings reveal that the majority of teachers have a shallow conceptual understanding of the principles of a thematic approach and this causes difficulties in their practice. The investigation concludes that in order for teachers to deepen their conceptual understanding of the thematic approach, follow-up workshops are necessary to help them develop appropriate strategies for their classrooms.

- Description: The Republic of South Africa embarked on devolution of specific powers to municipal authorities due to the fact that municipalities are a sphere of government which is at the door step of the citizens. Among the powers that were devolved was the authority to regulate on the rendering of water and services to communities. From now henceforth in this study, water and sanitation services will be referred to as water services. The rural villages that had no access to water services during the previous dispensation were rapidly rendered with these services when the transformed Department of Water Affairs and Forestry took a decision to provide the services on its own in order to give space for the transformation of the local sphere of government such that these municipal X authorities are able to manage the load of the allocation of such functions mainly and to close the vacuum so that there is no gap as to who should be responsible for water provision in rural villages whilst the restructuring of municipalities to include the rural villages as part of the transformation process takes place. A decline in the pace rendering water services to the previously disadvantaged rural communities was noticed after the devolution of water services to municipal authorities and by implication once hands were changed. This left those rural communities that had no access to water services still without the desired water services and those that had water services provided left midway with dry water schemes and dysfunctional infrastructure. This study therefore seeks to uproot the cause for the deceleration of water services once it was devolved to municipal authorities. This decline was noticed by the researcher hence the study seeks to attempt providing alternatives and lasting solutions primarily because water services are essential services and water is life. The main objective of the study is to investigate factors that cause the deceleration of water supply and the slow movement in the acceleration of sanitation services in order to provide alternatives that may yield results. Given the above broad objective this study further aims at examining the following factors: The correlation in funding made available by the central government and the financial resources available to municipalities to perform the function in order to render this service properly. Technical support available to municipalities. Relevant legislation, its policies and its impact on the implementation of the service XI. The correlation between accountability, democratization and community participation on standards and quality of the service to actual outputs. Improvement of service delivery and its relationship with transparency and efficiency. Relatedness of poverty to non provision of water services. The relatedness of poverty, lack of basic services to influx in the cities. Relatedness of the quality of the water services to the outbreak of diseases

- Description: The aim of this research study was to examine the role of traditional leadership during the upsurge of civil war in Southern Sudan. There has not been much research conducted in this field especially in Abiem County. Throughout the research process the role of traditional leaders has shown an unprecedented position during the liberation struggled characterized by huge support in terms of material support, manpower and political mobilization. The data analysis clearly reflected the roles of traditional leaders that occupied the historical perspective amidst the armed struggle waged by successive liberation movements and especially during the Sudan people’s Liberation Movement and Sudan People’s Liberation Army (SPLM/SPLA) from 1983 - 2004. It reflected on the vital roles of people’s support in the liberation movement represented by their traditional leaders, chiefs, elders, spiritual leaders, women and youth. Thus the perception of the role of traditional leadership in its different categories ha s shown a satisfactory and effective contribution to the war of liberation in Southern Sudan. However, in order to achieve the objectives, an investigation was conducted with various interviewees. As stated earlier, participants ranged from the chiefs and elders to local military and civil appointed administrators, women, youth and religious leaders. The main results of the study have profoundly asserted the important role of traditional leaders in the local government and their involvement in popular decision making and in local conflict management.

- Description: Red Pepper has been the subject of much discussion in Uganda, with some accounts describing it as a liberal mouthpiece, and others as pornography. This case study, therefore, sought to investigate Red Pepper as a media phenomenon in Uganda in the 21st century, specifically between 2001 and 2004. Employing quantitative and qualitative methodologies, it focused on the production process and the text. Although sexualised content dominate its pages, and news about issues such as the environment and education are near-absent, its managers describe the publication as legitimate, normative and consistent with liberal media standards. Accordingly, to interrogate Red Pepper in terms of its journalistic functions, selected debates associated with liberal approaches to news media, media political economy, tabloidisation, pornography and gendered relations were reviewed. The analysis entailed five phases. The first was a denotative or descriptive analysis, which focused on the publication's structure and content focus. This was followed by an interview with management, a broad content analysis to establish the incidence of predefined content categories expected of the tabloid, pornographic and liberal press and, lastly, a theme-based content analysis that sought to establish the potential meanings and framing of the dominant content categories of gossip and sexualised copy. Overall, the study found Red Pepper to be a misogynistic tabloid, having elements said to belong to pornography and homophobia. According to the findings, not only does Red Pepper fall short of a liberal understanding of a newspaper in terms of diversity of topics, provision of information and professional practice, it also does not fit the understanding of an alternative public sphere, mainly because it fails to challenge the patriarchal framing of sex, sexuality and gendered relations. This framing is undertaken deliberately as a means to securing economic rather than journalistic ideals to which the editors pay lip service. Consequently, the gossip and sexualised content are not problematised and as such discourses and power relations therein are not interrogated. Neither are inadequacies in local systems addressed nor corrective action mobilised as expected of some tabloids. All in all, the publication fronts superficial entertainment content that echoes particular gender constructions and patriarchal commonsense and entrenches the (undesirable) status quo which, ironically, it claims to challenge.

- Description: Lean philosophy is based on the continuous quest to improve the organisation’s processes by creating a culture and operating principles which eliminate all non value adding activities within organisation‘s processes. Manufacturing firms consider the adoption of the Lean tools as basic requirements for achieving World Class operational excellence or Best Practice. For some time, lean has been used by the manufacturing organizations. Most organizations understand that lean will help them survive global competition and stay in business. According to Hanna (2007:1), service industries, in general, are a long way behind manufacturing in terms of operations and improvements, and not all lean manufacturing ideas translate from the factory floor to office cubicle. The objective of this study is to investigate how lean manufacturing tools can be used to improve efficiency, customer service and enhance the embedding of a continuous improvement culture in the South African Revenue Services East London office Taxpayer Service business area. The activities that took place in the Taxpayer Service business area from 21 July 2008 until 31 October 2008 were observed. During the observation period, taxpayer services staff members were engaged formally, using surveys to assess their underlying mindset and behaviour as well as informally, using unstructured interviews to solicit more information on activities taking place and the reasoning behind certain actions. The movements of taxpayers who visited the branch office were monitored and the time it took for taxpayers to be assisted was measured as well as the time it took taxpayers to be assisted by a service agent or service consultant. To see if the available resources were used efficiently, the numbers of service channels available were compared to the number of service channels occupied. The results of the survey and observations are analysed and interpreted.

- Description: Lean philosophy is based on the continuous quest to improve the organisation’s processes by creating a culture and operating principles which eliminate all non value adding activities within organisation‘s processes. Manufacturing firms consider the adoption of the Lean tools as basic requirements for achieving World Class operational excellence or Best Practice. For some time, lean has been used by the manufacturing organizations. Most organizations understand that lean will help them survive global competition and stay in business. According to Hanna (2007:1), service industries, in general, are a long way behind manufacturing in terms of operations and improvements, and not all lean manufacturing ideas translate from the factory floor to office cubicle. The objective of this study is to investigate how lean manufacturing tools can be used to improve efficiency, customer service and enhance the embedding of a continuous improvement culture in the South African Revenue Services East London office Taxpayer Service business area. The activities that took place in the Taxpayer Service business area from 21 July 2008 until 31 October 2008 were observed. During the observation period, taxpayer services staff members were engaged formally, using surveys to assess their underlying mindset and behaviour as well as informally, using unstructured interviews to solicit more information on activities taking place and the reasoning behind certain actions. The movements of taxpayers who visited the branch office were monitored and the time it took for taxpayers to be assisted was measured as well as the time it took taxpayers to be assisted by a service agent or service consultant. To see if the available resources were used efficiently, the numbers of service channels available were compared to the number of service channels occupied. The results of the survey and observations are analysed and interpreted.

- Description: The first democratically elected government in South Africa came into power in 1994 and with this the whole country faced changes and new challenges. The construction industry faced the challenge of incorporating and empowering previously disadvantaged people that were part of the industry as well as new emerging contractors that entered the industry. Various training and mentoring programmes were initiated by government as well as quasi-government institutions which attempted to address these challenges. Having an effective mentoring programme in place in the construction industry is critical to the development and growth of the emerging contractors as well as the industry as a whole. This research focuses on a specific programme to establish if the need for training and mentoring programmes exist and which specific aspects of the training need the most attention. The study furthermore, investigates the effect the programme had on emerging contractors on the specific programme. Primary data was collected by means of a telephonic questionnaire to emerging contractors on the mentoring programme as well as the mentors and service providers of the programme. Secondary data was obtained from the literature reviewed and from relevant publications. The main findings were that a need for the training and mentoring of emerging contractors exists and the study emphasizes that there is a demand for the ongoing monitoring of emerging contractors after completion of the programme. The study furthermore reveals that all aspects of the training and mentoring programme is important but more time and effort should be spent on the management and financial aspects of the programme The research is limited to emerging contractors and mentors who participated in the East Cape Development Corporation (ECDC) mentoring programme in the Eastern Cape and is limited to two specific regions namely Port Elizabeth and East London. The findings from the study could be used by training providers as well as mentors to enhance the existing programme to ensure proper rounding of the emerging contractors.

- Description: The purpose of the research was to assess the policy impact of the Land Redistribution and Development (LRAD) Programme, which substituted the Settlement and Land Acquisition Grant (SLAG) programme. Both these policies were meant to make land accessible to previously disadvantaged groups including Africans, Coloureds and Indians, as part of land reform policies of the post 1994 democratic government. Due to some failures of SLAG after its first five years of implementation, which were from 1995 to 1999, the land redistribution policy was revised and the LRAD programme came as an improved policy of SLAG. There has not been much research on the impact of this programme, which has been implemented since August 2001.

- Description: Organizations globally are challenged with a very volatile, fast changing environment. It is only those organizations that develop the capacity to change timeously that will survive in this millennium. (Meyer & Botha, 2000, p.23) Organizational development (OD) is a planned change approach aimed at changing behaviour and enhancing organizational effectiveness. Central to such an approach is continuous business process improvement. OD rests on the foundation of values and assumptions about people and organizations, and it is imperative that organizations adopt systematic methodologies in introducing business improvement interventions. The study introduced an OD approach to one of the rural primary schools in the Omusati region of Namibia, with the purpose of examining if it would bring change in the school. My goal was to explore participants' experience and perception of the OD process and to investigate the possible short term outcome of such an intervention. The case study involved 16 staff members made up of a principal, one head of department and 14 teachers. Data was gathered through formal interviews with the principal, head of department and three teachers, through a focus group interview with teachers, and through observation and observation note entries. The study found that OD was a new concept approach to the participants which differs completely from the way that change processes are introduced in the schools. Participants felt that introducing change in an organization using an OD approach can bring effective change, but it can also place huge demands on participants' commitment. This is particularly so if they do not adopt it as an internal process of business improvement. The OD approach is a long-term change process and not a quick fix. Finally, the outcome of the intervention indicated enthusiasm for the school to continue addressing the prevailing challenges despite various obstacles that they do not have control over.

- Description: The research was conducted in the Hewu area situated between Queenstown (20 km) and Whittlesea (15km) in the Eastern Cape Province of South Africa. In this area communal farming is practiced. Livestock and livestock products (wool) are the main sources of income. The farmers are mainly farming with Merino and Döhne Merino sheep. The lack of management systems (production, reproduction and management) for communal farmers resulted into ineffective communal farming defining the research problem. The research objectives set were: • To establish production norms for wool sheep. • To establish reproduction norms for wool sheep. • To establish effective management practices for wool sheep farmers. • To examine key constraints of wool sheep farmers. The farmers shear their sheep every 12 months usually in October of every year. The average wool production per sheep is 2.17kg. The clip averages a fineness of 19.1-20 micron. That is far below the wool production of the commercial farmers of the Eastern Cape who are producing between 4kg to 5kg per sheep at an average growing period of 12 months. The lack of proper fencing and camps causes major reproduction problems. The lambing percentage of the ewes is 94.85 percent. The weaning percentage referring to the reproductive efficiency of the mated ewes is only 17.24 percent. The survival rate of the lambs born alive is only 18.18 percent. Reproduction is the biggest problem of communal farms. Effective livestock- and grazing management systems for communal areas are essential for the successful development of farmers on communal grazing areas. Unfortunately the Hewu farmers still have many problems effecting their wool production and the production of lambs.

- Description: Heat generation during the FTSW process plays and important role in determining the characteristics of the weld. In order to obtain temperature fields, a transient temperature heat analysis is required. An area is the maximum temperatures reached within the base material during the FTSW process. These temperatures will be measured during experimentation, and compared to the welding simulation done using FEA. From the literature search it appeared that no heat transfer analysis had been done using finite element methods.
