- Description: This study focuses on the effective implementation of C2005 by the Grade 7 teachers in the Motherwell area. For teachers to meet the demands of the new curriculum, in-service training is needed to develop them to be competent in all the aspects required for the use of the OBE approach. The main research question is: How have Grade 7 teachers in Motherwell implemented C2005 in their classrooms? Questionnaires and interviews were used as tools to collect the data. The data was collected from five selected primary schools in the Motherwell area. The teachers’ responses obtained from questionnaires and interviews were analyzed both statistically (using tables) and descriptively (telling teachers’ stories). Responses determined the competence of teachers in four areas, namely, teaching methods, content, classroom organization and assessment of learners. An account of inservice training courses attended by teachers is provided. These courses revealed the problems encountered by teachers during the implementation process and the subsequent assisstance they received. The data provided in this study is in line with the research done by the Review Committee (Chisholm, 2000) in the Eastern Cape. Recommendations of the Review Committee gave rise to the establishment of the Revised National Curriculum Statement (RNCS). The responses from this study confirmed the need for retraining of teachers to develop their competences. This study urges the Department of Education to focus on establishing methods of training that will develop teachers in their teaching experience. The SMTs should also be able to assist teachers with the problems they encounter in their schools. Teachers should be able to take responsibility for their learners’ competence and take ownership of changes in their schools. The financial assistance of the National Research Foundation towards this research is hereby acknowledged. Opinions expressed in this thesis and conclusions arrived at, are those of the author and not necessarily to be attributed to the National Research Foundation

- Description: This study examines the utility of the MMPI-2 in predicting responsibility in pre-trial forensic patients, using a post hoc sample of 94 offenders from Sterkfontein Psychiatric Hospital in Gauteng. Firstly, the overall characteristics of the pre-trial forensic patients are discussed, following an analysis of demographic, clinical, criminal and MMPI-2 pre-trial data, as well as an overview of the Megargee typological classification of offenders. The sample is classified into Criminally Responsible (CR), Diminished Criminal Responsibility (DCR) and Not Criminally Responsible (NCR), and the CR and DCR groups are collapsed (CR/DCR) for many of the analyses when comparing them to the NCR group. Secondly, the variance of variables with responsibility is discussed, after examining one-way ANOVA’s of demographic, clinical, criminal and MMPI-2 variables, as well as an overview of high point pairs. Thirdly, discriminant analyses were conducted of demographic, clinical and MMPI-2 variables. When comparing the collapsed CR/DCR group to the NCR group, psychiatric diagnosis, presence of psychosis, the MMPI-2 Pa and Es scales, as well as race and substance abuse each had unique predictive power and created a substantial discriminative equation (F (6,70) = 45.732, p <0.0005) with a successful prediction rate of 96%. Using only MMPI-2 variables to predict responsibility showed significant unique contributions for the Pa, Es, MAC-R and Mf scales, with the BIZ scale not quite significant, and a fairly significant overall discriminant equation (F (5,73) = 6.474, p < 0.0005), with an overall successful prediction rate of 82%, with the MMPI-2 variables adding an additional 3% to the predictive power of the demographic and clinical variables. Similarly, when examining the more complex 3 group responsibility classification of CR, DCR and NCR, it was found that the demographic, clinical and MMPI-2 variables of psychiatric diagnosis, psychosis, race, substance abuse, and the Pa, Es and Ma scales all had significant contributions to a powerful discriminant analysis (F (14, 136) = 19.758, p < 0.0005) that was capable of correctly reclassifying almost 95% of the sample, and the MMPI-2 variables providing an increase in predictive power of 8%. Differences in responsible and not responsible pre-trial forensic patients are discussed, as well as the role of the MMPI-2 in assessing these differences, and the fact that it is highly likely that it adds more to the forensic assessment of responsibility than a 3% (CR/DCR versus NCR) or 8% (CR versus DCR versus NCR) increase in predictive power. Limitations of the study are discussed, together with recommendations for future research with the MMPI-2 for assessment of criminal responsibility. The suggestion is made that the MMPI-2 can become a valuable tool in South African forensic settings, not only in the assessment of responsibility and malingering, but also in the placement, management, follow-up and treatment of offenders, to maximize the limited resources in South Africa allocated for the rehabilitation of offenders, and minimize the risk of recidivism or rehospitalization.

- Description: The objective of this study was to evaluate the current recruitment and selection policy of the Department of Water Affairs and Forestry (DWAF) and to determine whether the recruitment and selection practices comply therewith. To establish whether the policy enhances DWAF’s objective to improve its service delivery, a content analysis of the recruitment and selection policy was executed. To determine whether the recruitment and selection practices comply with the written and accepted policy a questionnaire was designed based on the provisions of the policy and best practices. The questionnaire was personally delivered to 50 potential respondents, of which 35 completed it. The completed questionnaires were processed and analysed using Microsoft Excel 2000. The policy was found to be well researched, comprehensive and efficient to DWAF’s missions and objectives. It however showed signs that indicate the danger of being applied inconsistently. Clarity in terms of procedural sequence and conditions for use eluded some policy provisions, making it acceptable to assume and base decisions on the users discretion. Trained human resource managers guide recruitment and selection practices. The study concluded that the policy was being implemented: the recruitment and selection practices within DWAF complied with its accepted policy. There are standardisation on advertising as recruitment method, and interviewing as selection method. The recruitment and selection activities that are not mentioned within the recruitment and selection policy are done at the line manager and human resource manager’s discretion - this is found to be inconsistent and potentially dangerous to the process. DWAF employs recruitment and selection as tool to enhance performance management and effective service delivery. Recommendations are made to assist DWAF in its quest to achieve maximum return on investment from its human capital.

- Description: Organisations today, regardless of their function, exist in an environment that is characterised by change. In order to maintain a competitive advantage it is vital that organisations manage such change and are sensitive to their human resource. It is imperative for organisations to understand and explore the factors that impact on employee satisfaction and overall organisational performance. The hospitality industry is an industry that is notorious for low levels of pay and long working hours, and often dissatisfied employees. This research focused on a hotel, that is part of an international chain of hotels, which has recently undergone a rebranding process (a change from within). This research aimed to assess and explore factors that impact on levels of employee satisfaction and organisation/hotel performance, in other words it aimed to 'diagnose' the hotel's current status. The research was conducted in two phases. Phase one made use of a widely used measure of job satisfaction, the job descriptive index (JDI), that looked at five facets of job satisfaction namely: pay, opportunity for promotion, co-workers, supervision and the nature of work. Phase two further explored the results of the JDI (staff being very dissatisfied with pay and promotions opportunity) and further explored other areas of the organisation/hotel with the use of an organisational development model, Weisbord's Six-Box Model (1990). The 'boxes' included areas of purpose, structure, relationships, leadership, rewards and helpful mechanisms. These areas were explored with staff using focus groups. Heads of departments (management) and the deputy general manager of the hotel were interviewed using a semi-structured interview format, exploring similar issues to those researched with staff. Results indicated problems in the hotel with regard to purpose, a severe lack of communication and staff feeling they have little chance for promotion as well as pay structures being perceived as unfair. The overall leadership at the hotel was described as erratic, and relationships between management revealed high levels of mistrust. Due to limited research in the South African hospitality industry, much of the literature available is based on experiences in the United States of America or the United Kingdom. For this research, the researcher had few previous published findings and was unsure of the many issues that could possibly arise. However, the intervention was enjoyable and recommendations have been provided for the hotel to consider, so the hotel can go from "good to great".

- Description: This study examines the graphic design industry’s call for ‘a South African design language’ in post-apartheid South Africa and how the non-commercial publication i-jusi is envisaged as a space for graphic designers to innovate a South African design language. The central premise of this research is that graphic design, as a form of cultural production, is discursive. In this respect, graphic design practice is constructed and constrained by professional discourse, which is in turn informed by social structures. However, discourse is also a site of contestation and graphic designers may challenge or negotiate professional discourse in their practice. Thus, as Wolff (1981) argues, the possibility for innovation within graphic design practice may exist at a particular historical moment, although this possibility is itself situated within social structures. In this study, the impact of professional graphic design discourse on the attempt to innovate a South African design language in i-jusi is explored. Utilising qualitative interviews and other texts selected from graphic design commentary (conference presentations and published articles), the motivations of the producers of i-jusi are examined with a view to assessing how their articulation of a South African design language is informed by professional graphic design discourse.

- Description: This thesis presents the findings of an exploration of teacher perceptions and actions to conserve wetlands in Kenya. It reports findings of a case study survey done with 54 primary school teachers from seven of eight Kenyan provinces. The teachers were sampled from a larger group of 242 teachers who participated in an in-service course on wetlands conservation. The in-service course engaged teachers in exploring various aspects of wetlands and how they could enhance their conservation using both formal and non-formal contexts. The survey approach was used in the research and was augmented with a reflective process. Survey tools used were the questionnaires and interviews. The reflective process entailed observation, document analysis, field notes and the researcher’s diary. Research data was analysed in several stages. The study revealed that teachers were users of local wetlands just like other members of their communities. The teachers differed among themselves with respect to their perceptions of the value and threats to their local wetlands. The teachers also differed in their perceptions of community awareness of their local wetlands. The teachers’ perceptions about environmental education and wetlands were not holistic. The teachers recorded various opportunities to foster wetlands conservation in their local contexts at school and the community. These were their fellow teachers, the pupils, the subjects taught, clubs, environmental days and the community. The relative importance of these opportunities differed among the teachers. Many teachers claimed being motivated to promote wetlands conservation using both formal and non-formal contexts. Their motivation was based on diverse aspects of wetlands, education and the in-service training they attended in 1999. However, the intensity of motivation differed for each aspect. For instance, at community level in-service training was a major motivator while the curriculum aspects were not mentioned at all. Teachers reported having involved their pupils and the community in several activities to conserve the local wetlands. These activities seemed to be dominated by theoretical approaches, eco-management activities and visits to wetlands. There was little evidence to indicate the teachers being engaged in addressing the implications for sustainability of the perceived local wetland values and threats. The activities reported also failed to show engagement with local environmental problems as a deliberate proactive process involving exploration, discussion, action taking and reflection. Most of the activities were presented as one off activities rather than as a cyclic continuously improving series of interventions. The overall scenario presented by the teachers is one of inadequacy in addressing the sustainable use of wetlands. Teachers suggested various constraints that affect their realisation of environmental education for wetlands sustainability. The constraints traverse various aspects of the economic, biophysical, political, educational and social aspects of wetlands conservation. The study suggested the need for teachers to treat their contextual and personal conceptions as problematic rather than as simplistic or linear issues and to formulate ways to address them. This study suggests a potential but under-utilised opportunity to promote wetlands sustainability. The overall picture generated by the data in this study is a need to consider wetland training for teachers that integrates the holistic aspects of wetlands as well as the environmental education for sustainability perspectives grounded in local contexts.

- Description: The US Bureau of the Census (1999) projected that by 2004, 14 million people in sub-Saharan Africa will develop full blown AIDS, making this region by far the largest disease burden in the world (World Health Organization, 2002). The United Nations AIDS Programme judged South Africa to have the leading number of people living with HIV/AIDS worldwide (World Health Organisation, 2002). To date there has been extensive research conducted on the socio-economic impacts of HIV/AIDS on families in Africa. However an area of investigation that has remained largely underreported is the inquiry into the psychological impacts of HIV/AIDS on elderly caregivers. In African families older women increasingly have to provide care to their adult children with AIDS and their orphaned grandchildren. However few research studies have assessed the experience of parental caregiving and its psychological impacts on these women. This qualitative research study hypothesised that the role of primary parental caregiver in fact causes a range of psychologically distressing states, which serve to compromise the psychological well-being of these caregivers. To investigate this hypothesis three Xhosa speaking women living in informal settlements in Grahamstown, in the Eastern Cape Province of South Africa were selected for the study. The women were interviewed by means of semi-structured interviews, which consisted of questions related to their caregiving experiences, their experiences of loss, their choice of coping strategies, the role of support networks and their experiences of foster care responsibilities. The interviews were transcribed and analysed using a grounded hermeneutic approach. The research results confirmed the working hypothesis. The research revealed that although it was considered culturally appropriate for older women to care for their children and grandchildren, their caregiver roles caused significant psychological distress. Their distress was related to: emotional and physical exhaustion, complicated grief reactions and ongoing emotional and physical upheaval related to foster care responsibilities.

- Description: The US Bureau of the Census (1999) projected that by 2004, 14 million people in sub-Saharan Africa will develop full blown AIDS, making this region by far the largest disease burden in the world (World Health Organization, 2002). The United Nations AIDS Programme judged South Africa to have the leading number of people living with HIV/AIDS worldwide (World Health Organisation, 2002). To date there has been extensive research conducted on the socio-economic impacts of HIV/AIDS on families in Africa. However an area of investigation that has remained largely underreported is the inquiry into the psychological impacts of HIV/AIDS on elderly caregivers. In African families older women increasingly have to provide care to their adult children with AIDS and their orphaned grandchildren. However few research studies have assessed the experience of parental caregiving and its psychological impacts on these women. This qualitative research study hypothesised that the role of primary parental caregiver in fact causes a range of psychologically distressing states, which serve to compromise the psychological well-being of these caregivers. To investigate this hypothesis three Xhosa speaking women living in informal settlements in Grahamstown, in the Eastern Cape Province of South Africa were selected for the study. The women were interviewed by means of semi-structured interviews, which consisted of questions related to their caregiving experiences, their experiences of loss, their choice of coping strategies, the role of support networks and their experiences of foster care responsibilities. The interviews were transcribed and analysed using a grounded hermeneutic approach. The research results confirmed the working hypothesis. The research revealed that although it was considered culturally appropriate for older women to care for their children and grandchildren, their caregiver roles caused significant psychological distress. Their distress was related to: emotional and physical exhaustion, complicated grief reactions and ongoing emotional and physical upheaval related to foster care responsibilities. Based on the results, the research recommendations emphasised the need for continual awareness of the psychological implications of caregiving for older African women with the aim to preserve their capacity to function as the primary caring resource to families struck by HIV/AIDS.

- Description: The aim of ergonomics is to identify any incompatibility between worker capabilities and the demands of their job. It is therefore desirable that in a developing country such as South Africa we have some basic, yet valid and usable means of measuring worker responses to physically demanding manual tasks. Extensive ergonomic research has been conducted in the controlled environment of laboratories around the globe, but only a limited number of investigations have been conducted in the workplace. This is due to the impossibility of controlling the extraneous factors such as the environment and changing workloads while assessing worker responses, plus the impracticality of using hi-tech equipment under difficult conditions on unsophisticated workers. The likelihood of obtaining ‘natural’ responses thereby is low. The focus of this study was to establish a less invasive means of assessing the physiological responses (specifically energy expenditure) of manual labourers working in the field. Twenty-three forestry stackers were assessed. Heart-rate responses were recorded during a full shift, after which the workers participated in a submaximal incremental step test. Subjects were fitted with a gas analyser, and heart rate and oxygen consumption responses were measured throughout the 12-min test. These data were used to establish a regression equation based on the relationship between heart rate and oxygen consumption (r² = 0.49; r = 0.69). Using this equation (y=0.26x – 6.42), one can measure heart rate in the field and predict the energy cost of manual tasks.

- Description: A detailed hydrographic and biological survey was carried out in the region of the South-West Indian Ridge during April 2004. Altimetry and hydrographic data have identified this region as an area of high flow variability. Hydrographic data revealed that here the Subantarctic Polar Front (SAF) and Antarctic Polar Front (APF) converge to form a highly intense frontal system. Water masses identified during the survey showed a distinct separation in properties between the northwestern and southeastern corners. In the north-west, water masses were distinctly Subantarctic (>8.5°C, salinity >34.2), suggesting that the SAF lay extremely far to the south. In the southeast corner water masses were typical of the Antarctic zone, showing a distinct subsurface temperature minimum of <2.5°C. Total integrated chl-a concentration during the survey ranged from 4.15 to 22.81 mg chl-a m[superscript (-2)], with the highest concentrations recorded at stations occupied in the frontal region. These data suggest that the region of the South-West Indian Ridge represents not only an area of elevated biological activity but also acts as a strong biogeographic barrier to the spatial distribution of zooplankton.

- Description: Against the backdrop of the growing problem of AIDS orphans in South Africa and greater sub-Saharan Africa, this qualitative enquiry examines the lives of three South African orphaned children living with HIV / AIDS in a children's home in Cape Town. It aims to generate rich, child-centred descriptions of some of the significant experiences of the children's lives. Drawings, dialogue and narrative were employed to generate the primary data. This was supplemented by collateral interviews and other relevant records, e.g. medical and biographical. Existential-phenomenological theory informed the approach to data collection and analysis. Each child produced a series often to twelve impromptu drawings over a period often weeks. These drawings and transcripts of the children's verbal descriptions of their drawings were extensively analysed. Significant themes for each participant as well as themes common to all three were identified. Some of the central themes emerging include loss, abandonment, death, disease awareness and coping. The children's ability to develop adaptive coping mechanisms and resilience in the face of traumatic loss and terminal illness was a particularly outstanding feature of the findings. Recommendations are made regarding future research to address the lack of qualitative, child-focused investigations as well as appropriate interventions for addressing the psychosocial needs of orphaned children living with HIV/AIDS.

Yet such is the case of R.L. Peteni, whose novel, Hill of Fools, was published by David Philip in South Africa in 1976, and internationally in the same year by Heinemann in the African Writers Series. Four years later, in 1980, the book was translated by the author into Xhosa as Kwazidenge and published by the Lovedale Press. Twenty years after initial publication, in 1996, there came a television version of Kwazidenge broadcast by the SABC, starring Willie Thambo and Amanda Quwe, though the locale was translated – in the bizarre logic of television – to an urban environment on the Cape Flats. The transposition, though pragmatic in terms of television demographics, destroyed much of the point of Peteni’s work, for Hill of Fools is South Africa’s first regional novel in English by a black writer. It is also the first novel in English by a Xhosa-speaker.

An investigation into how marketers cope with an environment of high complexity and turbulence, with special reference to the South African environment

- Description: This study investigated relationships between marketing success, the level of external environmental complexity and turbulence, and marketing mix tactics. The literature suggested that more successful companies in simple and stable environments use stabilising marketing tactics, while more successful companies in complex and turbulent environments use destabilising tactics, regardless of industry habits, management preferences or market sector. A marketing mix model for the different environments was developed using a chaos and complexity theory perspective. The study was exploratory, using a qualitative, case study technique. Data was collected via depth interviews and document analysis from four companies in the information technology (IT) and packaging industries. These industries were identified as, respectively, the most complex and turbulent, and the simplest and most stable, South African environments. Two companies from each industry were chosen to reflect more successful and less successful companies. The more successful company in the complex/turbulent environment was found to use destabilising tactics, as did the more successful company in the simple/stable environment. Therefore, contrary to expectations, it appears that destabilising tactics contribute more to success than stabilising tactics do, regardless of the environment. It was also found, contrary to expectations, that stabilising tactics were used by both the less successful companies. The research concluded that destabilising tactics are related to more success and stabilising tactics to less success. The lack of clear differentiation between the two industries may be because the whole South African environment is complex and turbulent, because the packaging industry is not sufficiently simple and stable to differentiate it from the IT industry or because packaging industry managers perceive their industry to be complex and turbulent and act accordingly. Despite these uncertainties, the research showed the marketing mix model to be reasonably accurate for the complex/turbulent environment, and therefore of potential value to South African companies. To overcome the equivocal findings, further research is recommended in different industries, in countries with different levels of complexity and turbulence and into specific marketing mix tactics. Research into managers’ perceptions of environmental complexity and turbulence and into co-evolution of marketing tactics and external environments would also be of value.

- Description: State-owned enterprises (SOE’s) in South Africa have long been financial albatrosses around the government’s neck. The government decided to restructure them so that they can play a role in the overall economic development of the country (Didiza, 2002:15). Transnet, one of South Africa’s largest SOE’s, is the largest transportation company in South Africa and is divided into various business units, of which Spoornet (rail transportation) is one. Spoornet has had to evolve from a subsidised state owned enterprise to a semi-privatised business unit, able to survive in a competitive business world. This entailed streamlining and restructuring the business unit in order for it to become more productive and financially fit. One of the biggest threats was the amount of human capital that Spoornet employed. The workforce had to be reduced in order to allow Spoornet to become an effective and competitive business unit. In addition to this, Spoornet must adhere to affirmative action policies instituted by government labour laws (Employment Equity Act, Act 55 of 1998). This act was introduced to redress the present effects of South Africa’s past in bringing about a diverse workforce broadly representing South Africa’s demographics. This has resulted in early retirement packages being offered to assist Spoornet in achieving employment equity targets. All of these changes have had a major impact on employee turnover that has resulted in a large amount of skills and expertise being lost. Professional, specialised and skilled people are in global demand, which has added to the exodus of employees from many organisations. Spoornet has experienced this at an alarming rate, so much so that in 2001, they established a retention committee to address ways to reverse the high number of specialised employee exits. Abstract iv The overall purpose of the research was to identify strategies for Spoornet to retain their specialised and skilled employees, thereby reducing the amount of specialised and skilled staff turnover. The research methodology for this study comprised the following steps: • Firstly, a full literature study regarding strategies that an organisation can utilise for the retention of their critical employees was researched. • Secondly, the views of current Spoornet employees on retention strategies were assessed in an empirical study, which involved completing a questionnaire. • Lastly, recommendations due to the findings of the researcher were identified for Spoornet to retain their highly skilled and specialised employees.

- Description: The assumption underlying this study is that cultures differ in terms of politeness norms. Often people from different cultures approach one another in what they think is an appropriate manner and the outcome is miscommunication. This may be attributed to differing cultural norms and this study aims to examine what a sample of school learners perceive to be polite behaviour when making requests and their reasons for doing so. This study focuses on perceived politeness norms (Brown and Levinson 1978) in English across selected South African cultures. The individuals are seen as reflecting a cultural identity, using norms that they feel are appropriate in given situations. Previous researchers have endeavoured to show that politeness norms are universal, but it has emerged that this is not always the case. When people from differing language and cultural backgrounds come into contact they have to find a common ground for their interaction to be successful (Lustig and Koester 1999). Of particular interest is the way people request things, both the way they phrase their request and their reasons for phrasing it this way. In order to investigate this, twenty-nine same-sex pairs of Grade 10 learners were selected from three schools with different cultural backgrounds in Grahamstown. These learners were required to complete a Discourse Completion Test, which contained both Think-Aloud and Retrospection Procedures, while they were being audio-taped. This data was transcribed and analysed using a model that was developed and adapted to describe request strategies. This data is shown through the use of basic statistics, even though it is primarily qualitative. The data is given this qualitative dimension by looking at the factors that the co-conversants attend to. The recorded data shows that although second language speakers of English have a formula for requesting things, they are not always able to articulate why they use the request strategies they do. It appears that English first language speakers and speakers who have English as an additional language request things similarly, but the first language speakers have access to a greater variety of politeness strategies. They also attend to different contextual features. This shows that while the need to be polite seems to be universal, the expectations of the speakers will be different and while a first language speaker of English would not misinterpret the force of a given speech act, they may feel that the person who has English as an additional language is rude. Sensitivity is therefore called for in order to combat mutual negative stereotyping and misunderstandings. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

The recorded data shows that although second language speakers of English have a formula for requesting things, they are not always able to articulate why they use the request strategies they do. It appears that English first language speakers and speakers who have English as an additional language request things similarly, but the first language speakers have access to a greater variety of politeness strategies. They also attend to different contextual features. This shows that while the need to be polite seems to be universal, the expectations of the speakers will be different and while a first language speaker of English would not misinterpret the force of a given speech act, they may feel that the person who has English as an additional language is rude. Sensitivity is therefore called for in order to combat mutual negative stereotyping and misunderstandings. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The purpose of this research was to investigate three principals’ perceptions and experience of participative management and to gain insight into and understanding of the dimensions involved in participative management from the perspective of the three principals. The research was conducted within the interpretive paradigm, since I was interested in understanding the subjective experience and individual perceptions of three principals with regard to participative management and the meaning they attach to it in their natural settings: how they describe, interpret and make sense of participative management. Data were collected by means of questionnaires, interviews and observation. The findings indicate overwhelming support for the notion that participative management (collegiality) does have a positive influence with regard to creating a sense of common goals, shared vision, a sense of ownership, commitment and improved human relations. The respondents emphasized the critical role of the leader in facilitating the implementation of collegiality as well as an increasing awareness of the potential of participative management to improve human development through delegation. The responses revealed interesting paradoxes with regard to the tensions between leadership and leaderless organizations, as well as between autonomy and interdependence. Responses also reflect the sentiment that participative management should be selective, involving only those with the necessary skills and expertise in the decision-making process. While there is an appreciation of the benefits to be derived from collegiality, critical statements about participative management include the time-consuming nature of participative management, and the notion that participative management impinges on the authority of the principals.

- Description: Lung infections in cystic fibrosis (CF) patients are very serious and are usually fatal. Prolonged antibiotic treatment can result in the development of antibiotic resistance. Thus, studies are required to determine if traditional medicinal plants have any significant effects (i.e. antibacterial effects in this case) on certain bacteria causing lung infections in CF patients, providing possible alternative treatment. The aim of this study was to test the effects of several Eastern Cape medicinal plants on specific bacteria causing lung infections in CF patients, for possible antibacterial activities. Four plants traditionally used to treat lung infections (Artemisia afra, Dodonaea angustifolia, Leonotis leonurus & Tulbaghia violacea), and different strains of four bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, Pseudomonas species & Klebsiella pneumoniae), usually causing lung infections were investigated. Methanol, aqueous and acetone extraction methods were used to make extracts of the various plants chosen. A decoction of each plant was also investigated. An adapted microtitre plate method for testing the antibacterial activity of the plant extracts against the chosen bacteria was used. The minimum inhibitory concentration (MIC) of each plant extract was determined by means of this method.

- Description: In an ever changing competitive environment, business is constantly faced with decisions. The ability to make informed decisions hinges on the organization’s power to properly integrate/position technology into the business processes of the organization. To stay in business organizations must be able to compete with rivals in their industry. The purpose of this research is to determine why the Geographic Information System (GIS) is not being utilized to its full potential. In order to determine the reason for this under utilization a literature study was undertaken with respect to GIS, how GIS is being positioned within PROPNET and what steps can be taken to improve the strategic positioning of GIS within PROPNET. A study was conducted which was limited to GIS professionals. An introduction to GIS is also given. A survey was then conducted within PROPNET. The survey covered competitive advantage, the value chain, kinds of information systems in relation to the different groups served within an organization and GIS. The results of the research survey corresponded with views expressed in the literature. Results concluded that GIS is incorrectly positioned within PROPNET for it to be competitive and that it should be repositioned within the operational level of the organization and utilized as a transaction processing system. The repositioning will lead to competitive advantage over rivals. Literature also revealed that GIS can be found in all sectors of the value chain. A strategy is proposed to reposition GIS within PROPNET. Recommendations are made to guide the repositioning. The subject field is new and there is little literature on GIS positioning and competitive advantage. There are significant advantages to repositioning GIS within PROPNET.

- Description: In general, insufficient research has been done to validate the usefulness and relevance of computers in educational settings (Hitchcock, 2000; Robinson et al., 2003; Baillie et al., 2000; Housego et al., 2000; Valdez et al., 2004). Schools therefore tend to adopt educational technologies before determining whether and how the technology will be used to its full capacity, or what the human and educational impact would be on learners and teachers (Hobson et al., 1998; McCabe et al., 2003; Hugo, 2002). In South Africa the eEducation policy, scripted by the Department of Education (DOE), has been created as an implementation and integration plan for educational technologies in South African schools, where all South African learners at schools are to be functionally computer literate by the year 2013 (DOE, 2003c). However, a limited amount of research has been performed investigating the educational relevance or optimal method for Computer Assisted Learning (CAL) implementation in South African schools. The purpose of the undertaken research study is to create an understanding of teachers’ attitudes toward CAL implementation and integration, as well as to provide insight into the optimal CAL implementation and integration methods in South African schools. The research problem under study therefore is: What are teachers’ attitudes toward the implementation and integration of CAL systems in South African schools? The research study is performed within the quantitative research paradigm and can be described as both exploratory and descriptive in orientation. In the context of this research the population under study is Grade 10 Mathematics teachers that teach in the city of Port Elizabeth. Out of a total of 153 teachers who form part of the study population, 78 successfully completed survey instruments, returning a high yield of 51% of the total study population. The analysis of the total teacher sample group provides the most statistically robust analysis breakdown of the study, and therefore can be reported with a high level of confidence. However, as the study is exploratory in nature, the analysis of various subject breakdowns have been included and iii reported in the study to provide anecdotal insight across diverse variable groups. Subject breakdowns include gender, demographic groups, and age groups, levels of qualifications and level of computer use experience. The findings indicate that teachers in general feel very positive about the use of computers in schools, specifically for teaching purposes, and believe the use of computers in education is inevitable but provides value in the educational context. Though teachers demonstrate high levels of access to computers and fairly capable computer abilities, they demonstrate low levels of awareness of available computer facilities, as well as low levels of computer use. The findings therefore indicate a need for greater integration of CAL systems into the curricula and greater training opportunities. However, teachers show that they have a preference for traditional teaching methods to CAL instructional methods, demonstrating a specific preference for traditional chalk and whiteboard media. The findings suggest that teachers do not value computers for their instructional purposes, but rather for their practical educational related activities. The findings also suggest that the use of computers to teach is not a priority of education related computer use. Teachers indicate that a variety of both traditional and modern media is best suited to various educational activities. With regard to CAL instruction, teachers demonstrate a preference for a teaching scenario where teachers use computers to prepare and teach lessons, but learners only perform exercises on computers under teacher supervision. Teachers demonstrate greater aversion to teaching situations where learners learn independently off computers. Teachers therefore indicate that Drill and Practice and Testing software are the most suitable for general CAL implementation and use, in support of previous studies in South Africa. Finally, from a developmental perspective in the context of South Africa, teachers overwhelmingly indicate that the widespread implementation of CAL systems should not occur before all schools have their basic needs of water, sanitation, electricity and human resources fulfilled.

- Description: The source of a reliable supply of seed is one of the most important factors determining the success of aquaculture. At present mud crab culture is reliant on wild caught juveniles, which limits the expansion of mud crab farming globally. This, coupled with the paucity of knowledge of the spawning and egg characteristics of mud crabs, prompted the investigation into the captive spawning, incubation and egg quality of Scylla serrata in South Africa. A total of 112 mature females were caught from three estuaries in northern KwaZulu Natal and acclimated to captive conditions. Mature females were present in the estuaries throughout the year and ranged from 90 to 200 mm carapace width. Except for 40 crabs all the females spawned in captivity. On average spawning took place 38 ± 23 days after capture but was not dependent on crab size. Fecundity was significantly correlated to crab size (p = 0.026), with larger females producing more eggs. The average fecundity per batch was 5.79 ± 2.07 million eggs. Hatch success rate for all egg batches was high averaging 84 ± 6 %. Egg dropping occurred in all egg batches during incubation. On average 6.5 % of the egg mass was dropped during incubation. At the average temperature of 27⁰C eggs in the incubation system hatched within 292 ± 12 hours after extrusion. In-vitro incubation of eggs proved to be an ineffective means of incubating Scylla serrata eggs with a hatch success rate of only 25 ± 5 %. Egg quality was assessed both directly, using variables such as hatch success rate and hatch synchronicity and retrospectively by using stress tests and comparing survival of larvae from different coloured egg batches. Lipid class composition and fatty acid methyl ester content for 28 batches of eggs and 16 batches of larvae were analyzed. The biochemical composition of the egg was correlated to survival of larvae in the stress tests to ascertain if the lipid content of the eggs determines their quality. Stress tests were used to retrospectively assess egg quality. Four stressors were administered to newly hatched larvae and the LD50 values recorded. An average LD50 of 64 hours was recorded for the starvation tests, 40% for the salinity tests, 37 ppm for the formalin tests and 39.7 mg/l NH3 for the ammonia stress tests was recorded. Egg colour ranged from pale yellow to orange-red. Egg colour was not influenced by female size or the time the females spent in captivity prior to spawning. Egg colour can therefore not be used as an indicator of quality. The lipid profiles of newly extruded eggs had no effect on hatch synchronicity or hatch success rate. However, the stress tests identified female size (p ≤ 0.02), DHA content of the egg (p ≤ 0.02), Σ omega-3 fatty acids of eggs (p ≤ 0.02) and EPA content of eggs (p ≤ 0.007) as possible determinants of egg quality. Larger crabs tended to produce poorer quality eggs. Egg quality also decreased as the amount of DHA, EPA and the Σ omega-3 fatty acids decreased in the eggs. To summarize, the results of this study indicated that the following parameters affect egg quality - crab size, DHA, EPA and Σ omega-3 fatty acid content of eggs.

- Description: There have been several changes in tourism in South Africa since 1994. During apartheid, black people were not allowed to become involved in important aspects of tourism, particularly at management level. However, this situation is changing and all cultures are gradually becoming engaged in th e tourism industry. The economic progress of the black community has resulted in the materialization of cultural villages, tourism projects to give rural people jobs, and an increase in township tourist attractions, heritage tours, etc. These initiatives have led to the establishment of certain types of tourism such as cultural tourism, urban tourism and community-based tourism. It could be said without hesitation, at the prescientific level, that the diversity in cultures, for one, is a major attraction of this country. Another change has been the increase in tourism from countries which have been excluded from South Africa in the past. Examples of these are African countries such as Kenya and Nigeria, as well as countries on other continents, including India, Bangladesh and the East-European bloc. Up to 2003/4, South Africa experienced the longest uninterrupted period of economic growth in its history. This resulted in people being able to afford a higher standard of living and therefore having more money to spend on travelling. as the economic growth stimulated the growth of tourism, both local and foreign, in the country. Seen from the perspective of the tourism industry, it is important to keep the public informed and up to date about what a country has to offer in order to maintain the increase in tourism. The media assist in this process. The travelling public is informed by word of mouth, but also through newspapers, magazines, television and radio. Information about the different attractions, whether cultures, wildlife or sport, et cetera, would not always be easy to find, were it not for the media. As tourism grows, more tourist attractions will develop, with a bigger need for tourists to be informed as an immediate result. The role of the media in this information giving is th erefore constantly on the increase.
