- Description: Psychobiographical research, with the use of psychological theory, allows us to uncover and unravel the life of an individual. This important area of research for the application of a psychological theory has, however, been under-utilized, especially in South Africa. The importance of psychobiographical case study research for the development and testing of theories of human development throughout the lifespan, has been supported by a number of academics in the field. The research subject was Sibella Margaretha (Isie) Krige. Isie (1870-1954) was married to General Jan Christiaan Smuts (1870-1950). He was a prominent South African and Commonwealth statesman, military leader, botanist and philosopher. Although much has been written on General Smuts, a psychobiography on the life of Isie had not been written yet. Isie was chosen as the research subject through purposive sampling. The study employed a qualitative psychobiographical research method, which aimed to explore and describe Isie’s psychological development in terms of Daniel Levinson’s (1996) theory of the Human Life Cycle. Collected data were analysed in accordance with Huberman and Miles’ (2000) approach. It integrated three sub-processes, namely data reduction, data display, as well as the drawing of conclusions and verification. The findings of the study indicate that Isie’s life was consistent with the pattern which Levinson (1996) identified. Isie was relatively successful in resolving the life tasks and transitional periods proposed by Levinson. The findings of the study also indicated that the development of Isie’s life structure was strongly influenced by a number of sociohistorical and global events. This research study has given a positive demonstration of the value of development theory. Furthermore, it emphasized the uniqueness of individuals in coping with the challenges of life. As a result it has opened up the possibility of perceiving people and their actions in a different way. Consequently, recommendations regarding the psychobiographical research design and methodology in future have been made.

- Description: The democracy in South Africa brought about many changes and new challenges. One such challenge was to transform the Higher Education institutes in South Africa. The National Commission on Higher Education (NCHE) resulted in the proposed National Plan for Higher Education in 2001. This referred to the restructuring of Higher Educational Institutes in South Africa. The National Plan for Higher Education listed priorities within section 6, which deals with the restructuring process. Some of these priorities referred to the reduction of duplications and overlaps in the programmes offered. Prior to 2005, Technikons offered the course National Diploma: Cost and Management Accounting over three years. Former Technikons developed their curricula for Cost and Management Accounting to utilise career orientated training in order to provide students with the necessary knowledge and skills for careers in financial and cost and management accounting as was applied in commerce and industry. Before the transformation and restructuring of the South African higher education institutions, Technikons in South Africa was part of a National system where a National curriculum was developed and implemented by all Technikons in South Africa. Curriculum development took place on a national level. Therefore, the programmes offered at these former Technikons were similar. Some of the former Technikons still offer the National Diploma in Cost and Management Accounting but in a different format. Students registering for this programme, register for a National Higher Certificate (NHC) in Accountancy. The duration of this NHC is two years where after students can complete a third year to graduate with a National Diploma in Cost and Management Accounting. The NHC in Accountancy was also developed on a national level and the curricula are similar at the higher education institutions offering it in South Africa. Since the merger of higher education institutions in South Africa, the responsibility to develop new programmes shifted from a national level to an institutional level. The newly merged institutions carry the responsibility to develop new programmes which suites the specific institution and serves the need of the specific communities. The iv primary objective of this study is to analyse the Cost and Management Accounting curricula in South Africa with the intention to propose a new curriculum for this diploma. To suggest a proposed curriculum, the old curricula of the various South African institutions were considered using qualitative research methods. The four South African institutions and the two Australian institutions were analysed and a balanced curriculum proposed out of this information. The proposed curriculum for the diploma in accounting, combined subjects that have been offered previously and subjects that could further expand graduate employability. Five companies were selected to evaluate the proposed curriculum. After considering the views of all the interviewed employers, a final curriculum was suggested for the Diploma in Accounting. As a result of this study it was clear that in-service training should be added to the Diploma in Accounting. Eighty percent of the interviewed potential employers suggested that practical experience in third year studies would significantly enhance student employability. Cost and Management Accounting has long been used by accountants to help managers understand the different costs of running a business. It is important for managers to identify certain areas of the business process where costs can be cut and the profitability increased. From this study it is clear that the proposed curriculum is acceptable to employers as they found that students will benefit from it.

- Description: High frequency, HF (3 - 30 MHz), radio communications are greatly affected by ionospheric conditions. Both civilian and military users need reliable, real time propagation information to show at any time the feasibility of communicating to any part of the world on a particular frequency band. For this thesis, an automated receiving/monitoring station for the Northern California DX Foundation (NCDXF)/ International Amateur Radio Union (IARU) International Beacon Project was setup at the Hermanus Magnetic Observatory, HMO (34.42oS, 19.22oE) to monitor international beacons on 20 m, 17 m, 15 m, 12 m and 10 m bands. The beacons form a world wide multiband network. The task of monitoring the beacons was broken down into two steps. Initially the single band station, at 14.10 MHz, was installed and later it was upgraded to a multiband station capable of automatically monitoring all the five HF bands. The single band station setup involved the construction and installation of the half-wave dipole antenna, construction and installation of an HF choke balun; and the choice of Faros 1.3 as the appropriate monitoring software. The multiband monitoring station set-up involved the installation of an MFJ-1778 G5RV multiband antenna, construction and installation of a Communication Interface - V (CI-V) level converter and configuring the Faros 1.3 software to monitor the beacons on all five HF bands. Then a web page was created on the HMO space weather website (http://spaceweather.hmo.ac.za). Here, the real-time signal to noise ratio (SNR) and short path (SP)/long path (LP) plots are uploaded every 3 minutes, showing real time HF propagation conditions on the five HF bands. Historical propagation data are archived for later analysis. A preliminary data analysis was done to confirm the peration of the monitoring station. The archived data were analysed and compared to ICEPAC (Ionospheric Communications Enhanced Profile Analysis and Circuit) predictions. Results show that the real-time signal plots as well as the archive of historical signal plots, convey information on ropagation conditions to users in terms that are easy to interpret and understand.

- Description: Alien invasive species pose a great threat to ecosystems and human communities (Richardson & van Wilgen 2004; Hobbs & Humphries 1995). On private lands, there is a need to find institutional, administrative and scientific responses to the alien plant problem that operate beyond the scale imposed by property boundaries (Slocombe 1998; Grumbine 1994). One such response is the development and support of institutions, such as the St Francis Conservancy, that foster cross-boundary management of landscapes (Hurley et al. 2002). This study seeks to promote collective decision-making and collaborative management by private landowners through the development of a resource allocation system for the control of alien invasive plants on the St Francis Conservancy. The conservancy is located in the south-eastern lowlands of the Cape Floristic Region, between the villages of Cape St Francis and Oyster Bay, and is comprised of the properties of multiple landowners. Mutliple Criteria Decision Analysis (MCDA) and Geographical Information Systems (GIS) techniques were integrated to provide a spatially explicit resource allocation system that considered environmental, social and economic concerns. The MCDA technique selected for use was the Analytical Hierarchy Process (AHP). This technique has a record of providing robust, defensible decisions and enabled the resource allocation decision-problem to be decomposed into a hierarchy of objectives, criteria and indicators. Stakeholders participated in the development of the resource allocation system, especially through providing input into the determination of the relative importance of criteria and indicators through the assignment of weights. Various weighting scenarios were presented and these were interpreted into an ii implementation plan. The costs and effort required to clear alien plants were estimated, and obstacles facing the implementation of the plan were identified.

- Description: Public participation in water management processes is one of the internationally recognised and adopted principles of Integrated Water Resource Management. The South African Department of Water Affairs and Forestry aims to facilitate the decentralisation of water management powers to the local community level via the establishment of regional and local water management institutions, namely Catchment Management Agencies, Water User Associations and Catchment Forums. The National Water Act (No. 36 of 1998) acknowledges that the discriminatory laws and practices of the past have prevented equal access to water and the use of water resources. The contribution of water management institutions to social and economic development, in particular poverty eradication and food security, is mentioned in the water act. The participation of poor rural communities living in the Kat valley, an area where an elite minority reap the benefits of water use for agriculture, is the focus of this research. Their participation, perceptions and experiences are documented and explored to determine how the promulgation of post-apartheid water policy and legislation has affected their access to water. The results of this research are based on data collected from several methods including surveys, workshops and observation. Analysis of these data revealed the complicated and stagnant nature of participation from Kat valley rural communities in local water management initiatives and organisations. Existing water management organisations were not successful in stimulating poor people’s participation as they were unable to address their primary concerns, namely a secure source of potable water, employment and access to water for agricultural purposes. This thesis asserts that the Department of Water Affairs and Forestry, as the custodian of South Africa’s water resources, has not taken on a supportive, accountable role in assisting marginalised communities with improving their access to water for domestic purposes and securing access to water rights for productive use. This, in turn, has led to dissatisfaction among these communities and a wariness of participatory activities that focus mainly on raising environmental awareness. The establishment of effective accountability relationships among all stakeholders, pro-poor water management structures and initiatives, as well as integrated and co-operative management of natural resources, are needed to revitalise the present participation of poor communities living in rural areas.

- Description: This thesis examines the development of Grahamstown from its inception in 1812 to the mid-1840s, paying particular attention to the social and cultural life of the town. It traces the economic development of the town from a military outpost to a thriving commercial settlement, noting the essential factor of the town's proximity to the Cape frontier in this process. The economic interaction between diverse groups in the town mirrors the social and cultural interaction which occurred between British settlers, Khoekhoe and Africans. The result of these interactions was the creation of a new, distinctively South African urban society and culture, despite the desire of the white settlers to reproduce a “typical” English environment in their new home. The conflict between attempts to anglicise the urban environment and the realities of Grahamstown's situation on a colonial frontier was reflected in the architecture and layout of the town. Attempts to recreate an English social environment also failed. New classes arose in the town in response to the economic opportunities available on the frontier. Although some settlers prospered, many did not, and the presence of an impoverished white working class undermines settler historians' picture of settler success and affluence. The poorest people in the town, though, were the increasing numbers of Khoekhoe and Africans who migrated from the surrounding countryside, and who were unequally incorporated into the urban community as a colonial labouring class. In response to these unique circumstances, white settlers in Grahamstown developed a powerful political and propaganda machine, which helped lay the foundations of a distinct settler identity in the eastern Cape.

- Description: The main aim of this study was to assess the impact of the Best Management Practices (BMP) project on social and economic wellbeing at Zanyokwe Irrigation Scheme (ZIS) in central Eastern Cape Province. The BMP project is a knowledge-based initiative aimed at introducing management practices (mainly soft skills) in order to improve production and livelihoods in the study area. The study employed a survey to collect socio-economic data amongst farming households. The 2005 situation analysis, which was conducted amongst the same respondents before the introduction of the new practices allowed for comparisons in order to track changes or impacts after the implementation of the project. Also, the social and economic impact assessment (SEIA) framework was used to assess the impacts. The results of the impact assessment showed the BMP project to have an impact on social and economic well being of households. The skills introduced were in the areas of water management, agronomic practices, marketing and institutional arrangements. More than 90% indicated that there was improvement in agronomic practices and water management and 68% in marketing. More than half of farmers worked in their farms on a daily basis, which is a big change as none of the farmers worked during weekends in 2005. The average time spent on the farms also increased from four (in 2005) to seven hours (this investigation) on average per day. The BMP project also had a positive impact on social relationships and networks between farmers and the BMP project team as well as well as farmers and non-farmers. Land use intensity improved due to increases in acreage of main crops as well as cultivating at both seasons. More than 40% of farmers cropped their land at both seasons (winter and summer). In 2005, most of the land was fallow in winter. While some of the new practices introduced had a negative impact on input expenditures, the returns were positive. These extra efforts and expenditures resulted in improvement in incomes. Agricultural contribution to household income increased from 71% in 2005 to 81% in 2007. The increase in household incomes had a positive effect on poverty and food security status of households. The proportion of households earning incomes that are below poverty line dropped from 61% in 2005 to 38% in 2007. Changes in the diet of the households were noticed. In addition to the consumption of staples such as samp, maize meal and rice, people added a variety of vegetables. Own production was the main source of these vegetables as was indicated by 66% of respondents compared to only 25% in 2005. Food remained the main expenditure category though, as was the case in 2005. Improvements in marketing such as performing extra marketing functions and adopting a marketing strategy (collective action) also led to improvements in economic wellbeing.

- Description: The main aim of this study was to assess the impact of the Best Management Practices (BMP) project on social and economic wellbeing at Zanyokwe Irrigation Scheme (ZIS) in central Eastern Cape Province. The BMP project is a knowledge-based initiative aimed at introducing management practices (mainly soft skills) in order to improve production and livelihoods in the study area. The study employed a survey to collect socio-economic data amongst farming households. The 2005 situation analysis, which was conducted amongst the same respondents before the introduction of the new practices allowed for comparisons in order to track changes or impacts after the implementation of the project. Also, the social and economic impact assessment (SEIA) framework was used to assess the impacts. The results of the impact assessment showed the BMP project to have an impact on social and economic well being of households. The skills introduced were in the areas of water management, agronomic practices, marketing and institutional arrangements. More than 90% indicated that there was improvement in agronomic practices and water management and 68% in marketing. More than half of farmers worked in their farms on a daily basis, which is a big change as none of the farmers worked during weekends in 2005. The average time spent on the farms also increased from four (in 2005) to seven hours (this investigation) on average per day. The BMP project also had a positive impact on social relationships and networks between farmers and the BMP project team as well as well as farmers and non-farmers.

- Type: Thesis , Masters , MSc

- Description: In this study a method was developed to identify and quantify platinum(II) complexes of the type [PtCl4-n(OH)n]2- and [PtCl4-n(H2O)n]2-n. Separation of the various species was achieved with the aid of a hyphenated reversed phase HPLC-ICP-MS technique coupled with an ion-pairing reagent, HMHDCl2. The adsorption of HMHD2+ onto a C-18 column was investigated by generating a series of breakthrough curves. It was found that the selectivity for high charge density anions originates from its low surface coverage relative to TBA+, which on the other hand could not separate Pt(II) complexes. The peaks in the chromatographic traces were assigned by following the stepwise ligand substitution of [PtCl4]2- in hydroxide medium with UV/Vis spectrophotometry and HPLC-ICP-MS simultaneously. A computer program was written by the author to analyse chromatographic data by deconvoluting the chromatogram into its individual components and calculating the mole fraction of each component. The validity of the consecutive pseudo-first order model was validated by constructing 3D Mauser diagrams with the raw spectrophotometric data (A1 vs A2 vs A3). Additional software was used to simulate the raw spectrophotometric data and processed chromatographic data. The pseudo-first order rate constants obtained in both cases were in agreement with each other. Hence, peaks were assigned to [PtCl4]2-, [PtCl3(OH)]2-, [PtCl2(OH)2]2-, [PtCl3(H2O)]-. The molar extinction coefficient spectra of [PtCl3(OH)]2- and [PtCl2(OH)2]2- were obtained by simulating the spectrophotometric data at wavelengths from 280 to 450 nm. The reaction of [PtCl4]2- with sodium hydroxide was investigated with UV/Vis spectrophotometry at 25 °C. A rate constant consisting of a first and second order term was obtained. The first order term agreed with what has been reported in the literature for aquation of [PtCl4]2- at 25 degrees C. The influence of temperature was established by conducting the experiment at different temperatures. It was found that the reaction proceeds essentially via aquation at elevated temperatures.

- Description: Since the inception of the new dispensation, entrepreneurship has been identified as one of the key enablers of economic participation. For this reason the government has established strategic institutions and mandated them to promote entrepreneurship in the country with the aim of increasing economic participation and entrepreneurial activities. One of the key and the fastest growing industries that have been identified as needing attention with regards to increasing participation of the women entrepreneurs is the tourism industry. There is now a noticeable growth of women entrepreneurs in this industry. They are found running bed and breakfasts (B&Bs) and conducting tours in urban areas as well as townships and rural areas. This is further evident if one looks at the value chain in the tourism sector. However, women entrepreneurs that are found in this sector are facing specific challenges that hinder their progress towards achieving sustainable businesses, especially those running or intending to run B&B businesses. Some of these challenges are sector related and some are just inherent to pursuing an entrepreneurial journey. The participation of women in the mainstream of entrepreneurship presents unique challenges as well. Women were never allowed to participate fully in the entrepreneurial activities. The latter still contributes to the challenges faced by women in their journey towards developing and operating sustainable businesses irrespective of the industry in which they operate in. Based on the above discussion, the main problem statement of this study is: To develop a strategic entrepreneurial model to enable female entrepreneurs to operate sustainable B&B businesses in the tourism industry.

- Description: Employed individuals spend a majority of their waking time at work. Therefore, within an individual’s working lifetime, most hours will be spent at work. Subsequently, theories abound purporting that humans are hedonistic beings. Considering that on average people spend most of their working lives in a working environment, it then stands to reason that people should endeavor to be satisfied at work if humans are always in pursuit of happiness. The questions arise as thus: what makes people satisfied at work, does being satisfied with the job result in less turnover, and is that the only reason that they would endeavor to prolong their employment, are older employees more satisfied with their jobs than younger employees, is a plant with an older workforce more satisfied than a similar plant with a younger workforce? This study attempts to find an answer to these and other related questions. It was conducted on employees of two plants of an automotive manufacturer based in Port Elizabeth, a town in the Eastern Cape province of South Africa. The Job Descriptive Index (JDI) was used to collect the feelings of 92 employees in different shops and analyzed to check for differences in satisfaction levels. No significant differences were found between the plants, shops and age categories surveyed.

- Description: The increased abscondment of Mental Health Care Users from institutions of care, treatment and rehabilitation has prompted the researcher to conduct the study because patients who are not visited do not stand a chance of getting a Leave Of Absence (LOA). Problem: The concern is the danger of assault, murder, rape and other high risk situations the mentally ill individuals and the community are exposed to, which is caused by frequent abscondment of mentally unstable individuals who roam around the community without proper treatment and care. This is caused by failure of the relatives in coming to request patients for leave of absence (LOA). Purpose: The study investigated the effects of mental illness on relationships amongst families with the mentally ill members. The number or frequency of visitations by relatives to the mental health institutions is used by the researcher, to measure the nature of relationships between families and the psychiatric patients related to them. Method: The population comprised families of the mentally ill persons admitted at Cecilia Makiwane mental health units. The sample was collected conveniently as relatives came to visit the mentally ill until the desired number was reached. The designed tool was a questionnaire which was self administered. Data were analysed manually. Tables and graphs are shown in the results. Conclusion and Recommendations: The study revealed that approximately 100% of respondents had a lack of knowledge about mental illness and the mentally ill, in terms of care, treatment and rehabilitation hence they all need assistance in dealing with the mentally ill in the community. Findings also revealed that mental illness causes breakdown in family relationships. Recommendations regarding the enhancement of relationships between families and their mentally ill members are formulated as coping skills in the dissertation. The burden of having to deal with mentally ill person whose illness is not understood can lead the family to a state of confusion and iv not knowing what to anticipate. Lack of resources compounds the problem as the family members are not able to visit the ill member due to lack of funds (Baumann, 2007:637). The families with a mentally ill member usually shoulder the greatest part of the burden of mental illness (Uys and Middleton, 2004:77); unfortunately, lack of resources pose a problem.

- Description: Internationally, the practice of admissions entry testing in Higher Education (HE) has gained momentum over the past few decades, sparking ongoing research on its effectiveness. On a national level, three factors have signalled a timeous evaluation of admissions practices at HE institutions. Firstly, changes in the school curriculum and the new format of the National Senior Certificate (NSC) have impacted on the admissions criteria of HE institutions. Secondly, with the merging of HE institutions an alignment in admissions practices between the institutions involved were necessitated. Thirdly, South Africa has embarked on the development of National Benchmark Tests (NBTs). The primary aim of this research study was to develop a set of recommendations to guide admissions testing practices in the South African HE context. These recommendations had to place special emphasis on the multicultural and multilingual context of this country. To achieve this aim a systematic review was conducted on HE admissions testing in Israel, as it was identified as a multicultural and multilingual country that had successfully implemented national HE admissions testing. More specifically, a retrospective systematic review was performed on research regarding the national HE admissions test, the Psychometric Entrance Test (PET), used in Israel. The systematic review also contained a narrative overview on the educational landscape in Israel and the specifications of the PET, from which themes were also extracted. Eight broad themes emerged through the systematic review and narrative overview as being of critical importance to an effective national HE admissions test. These were the components of the test, the implementation of the testing programme, the method in which the test results are used to make HE admission decisions, the reliability xi of the test, the validity of the test, bias inherent in the test, other psychometric aspects related to the admissions test, and the effect of coaching or specialized preparation on test results. These themes, together with their sub-components, were used to develop eight recommendations that can guide the development and implementation of the National Benchmark Test (NBTs) in South Africa. Both the themes that emerged during the systematic review and narrative overview as well as the recommendations that were made to guide the development and implementation of a national admission test, represent an important contribution to the field of admission testing and decision-making in South Africa.

Mobile Preference-Based Search Tools (PBSTs) allow users to identify POIs such as restaurants or accommodation most suited to their needs and constraints using a mobile device. These devices however, have several design constraints including limited screen space and hardware capabilities. Adaptive User Interfaces (AUIs) have been proposed to address these issues but have not been extensively applied to mobile PBSTs such as mobile tourist guides. In addition, AUIs possess several benefits and advantages over static (traditional) interfaces, which do not take a user's preferences, skill set and experience into account. Little research, however, has been conducted into identifying the potential benefits of AUIs for mobile preference-based searching (PBS). The aim of this research was to determine the extent to which an AUI could improve the effectiveness and user satisfaction of mobile PBS. A literature study was conducted to determine the benefits and limitations of existing mobile PBSTs and determine how these could be improved. The potential benefits of AUIs for mobile PBSTs and a mobile map-based visualisation system were identified. A suitable model for incorporating an AUI into a mobile PBST was identified. The requirements for a mobile PBST were combined with the potentially adaptable objects of a Mobile Map-based Visualisation (MMV) system to provide adaptation suggestions for POInter, an existing mobile tourist guide. A field study using POInter was conducted in order to measure the extent to which participants agreed with suggestions provided for adapting the information, interaction and visualisation aspects of the system. These results were used to derive adaptation requirements for A-POInter, an adaptive version of POInter. Using a model-based design approach, an AUI was designed and implemented for A-POInter. An extensive field study was then conducted to evaluate the usability of the adaptations provided by A-POInter. The quantitative and qualitative data collected from the evaluations allowed the usability of A-POInter to be determined. The results of the field study showed that the participants were highly satisfied with the usability and the usefulness of the adaptations provided by A-POInter. Conclusions and recommendations for future work based on the results of the research were then outlined to conclude the dissertation.

- Description: Societal trends have changed more in the last decade than they have in the last century. This is particularly prevalent in the education environment. Concepts such as Lifelong Learning (the continued learning/educating of an individual throughout his/her lifetime), New Competencies (technology that is now part of almost every skill in the workplace) and Telecommuting (more people working from home rather than traditional offices) have become common-place today (Twigg, 1996, pp. 1-2). Education delivery needs to provide for these societal changes in order to ensure competent individuals pass on to the next level of education and ultimately to the work force. With key trends in technology such as Digitization, Maturation and Disintermediation becoming common in the workplace, education delivery must address the ―Digital Divide. (Twigg, 1996, pp. 2-3). Historically, schools in South Africa have used traditional teaching methods that have stayed the same for the last century. Educational institutions in South Africa, in particular, the previously disadvantaged schools of the Eastern Cape, face various challenges such as the dwindling ability to collect school fees from parents of scholars and declining financial support from the government. In Chapter Seven of the Draft White Paper on e-Education, which was gazetted on 26 August, 2004, the DoE, as part of its implementation strategies, urged the private sector to respond by implementing ICT initiatives nationwide. Phase 1 of the strategy advocated that ―Institutions are connected, access the internet and communicate electronically. (Department of Education, 2004, pp. 37-40). This dissertation shows that it is feasible to create a communications’ network among South African schools. It is believed that such a network can add great value to the education system in South Africa. The potential for this network to address the gap in the Digital Divide is enormous. This dissertation examines various ICT communications’ technologies and isolates wireless communications’ technology as best suited for this purpose, due to the speeds offered by the technology and the cost structure associated with it. A case study examines a pilot installation of the network and endeavours to prove the concept.

- Description: This treatise provides recorder performers and teachers with a guide to understanding the unconventional notation symbols encountered in Music for a Bird by Hans-Martin Linde and Sieben Stücke Für Altblockflöte by Markus Zahnhausen. Given the context of the overall history of notation, it argues that the idiosyncrasies of the unconventional notation symbols encountered in the recorder repertoire of contemporary composers such as Linde and Zahnhausen are by no means an anomaly. Throughout history, notated scores have functioned merely as incomplete guides to the reconstruction and the realization of musical works. Along with the decoding of these instructions, a host of acculturated meanings have always been taken for granted on the part of the writers of such guidelines. In the light of the modernist crisis and the resultant exacerbation of the gulf between composers and their audience, however, it would seem that the need for such acculturated intervention is greater then ever before. This treatise serves to bridge the gulf between the works of Linde and Zahnhausen on the one hand, and the average performer and teacher of the recorder on the other, by offering an analysis both of the meaning of the unconventional symbols these works contain as well as of the method according to which they should be executed on the recorder.

- Description: This study investigated whether the PGCE adequately develops the WIL skills of student teachers. WIL skills have contributed extensively to the effectiveness of the facilitation of teaching and learning in schools. The definitions of WIL in this study refer to the skills required to succeed in practice. The four domains of Danielson provide the WIL skills, namely Preparation and Planning, the School Environment, Instruction and Professional Responsibilities. The study showed that there is a link between the four domains and the capacity of student teachers to integrate the theory they acquire at the HEIs and practice in the schools. The quantitative approach is referred to by Creswell (2005:39) as a type of educational research in which the researcher decides what to study, asks specific narrow questions, collects numeric data, which is numbered data from participants, analyzes these numbers using statistics, and conducts the inquiry in an unbiased, objective manner. As this study requires numeric data that ask specific questions, two questionnaires were distributed. One questionnaire was directed at school – based mentors and the other at PGCE student teachers. The mentors rated the students’ capacity in the four domains and the students rated themselves on the same items based on the four domains. The research instrument provides insight from school-based mentors with regard to whether there is a balance between the theoretical knowledge provided by HEIs and the WIL skills that student - teachers need. The questionnaires completed by PGCE student teachers provided perspectives from the students with regard to the relevance of their WIL skills for the schools at which they were placed. The hypothesis for this study is: The PGCE makes a significant contribution to the development of the WIL skills of ITE student teachers. Some of Some of the key findings in this study indicated that: • Constant curriculum changes in the schools create uncertainty for student teachers. • Student teachers need assistance to motivate learners to take pride in their work and achievements. • Managing learner behaviour is cause for concern for student teachers. • Language proficiency continues to be problematic in the teaching and learning environment, because it impacts on questioning, discussion techniques and the student teachers’ capacity to explain concepts. • Student teachers need assistance with the pacing of their lessons. • Adjusting their lessons, which requires spontaneity from student teachers is needed. • Opportunities need to be created for student teachers to gain access to the parents of their learners. • Student teachers need to devote more time to the development of reflective skills. • Excessive administrative tasks hamper delivery in the classroom and teacher and learner productivity. The findings strongly suggested that a significant relationship exists between the WIL skills of PGCE students and their effectiveness as facilitators of learning. The findings of the study indicated that the PGCE curriculum needs to incorporate the crucial WIL skills as identified in the four domains. The findings of this study supported the hypothesis that the PGCE makes a significant contribution to the development of the WIL skills of Initial Teacher Education student teachers (ITE).

- Description: The introduction of antiretroviral drugs (ARVs) in 1996 transformed the treatment of HIV and AIDS, improving the quality and greatly prolonging the lives of many infected people. HIV (Human Immunodeficiency Virus) is the virus that is believed to cause AIDS. AIDS (Acquired Immune Deficiency Syndrome) is the collection of illnesses or symptoms that ultimately results in death. Antiretroviral (ARVs) drugs or Highly Active Antiretroviral Therapy (HAART) is the treatment that has been applied to combat the HI virus in a bid to slow down the progression of AIDS and ultimately prolong the life of the infected individual. The study aimed to explore and describe the factors contributing to adherence and non-adherence to ARVs in individuals on treatment. A sample of 81 individuals who have been on ARV and HAART treatment for six months or more was used. The methodology used was exploratory-descriptive and the data obtained was quantitative in nature. A biographical questionnaire and questionnaire with questions aimed at ascertaining the possible factors that contribute to individuals either adhering to or defaulting on their treatment, such as side effects and cost of treatment, was administered. The data obtained was analysed by means of descriptive statistics and frequency counts. The results of the study showed that the sample had a fairly high level of adherence. The factors that could undermine adherence were identified as lack of support, as familial and health provider support acts as a motivator to adhere; substance abuse as it can lead to forgetting to take treatment; unemployment and poverty, as these can lead to an inability to return for follow up clinic visits or failure to have food to take with the pills; and the type of treatment regimen whereby the more complex the treatment is the more likely it is that adherence will be difficult to maintain. Suggestions were made as to future research involving antiretroviral therapy (ART). Finally the limitations as well as the value of the research were outlined.

- Description: African Potato (Hypoxis hemerocallidea), (AP) is an African traditional medicine (TM) that is commonly used for various nutritional/medicinal purposes and also by people infected with the human immuno deficiency virus HIV and AIDS patients as an immune booster. The use of AP has also been recommended by the former Minister of Health of South Africa for use by HIV positive people. The main phytochemical component of AP is a norlignan glucoside, hypoxoside, and other relatively minor components have also been reported. A recent in vitro study reported the effects of AP extracts, hypoxoside and rooperol (the metabolite of hypoxoside) on human metabolic enzymes such as the cytochrome P450 (CYP450) group of enzymes and also on the transporter protein, p-glycoprotein (P-gp). This research focussed on investigating the clinical significance of those in vitro effects on the pharmacokinetics of efavirenz (EFV) in humans. EFV was chosen as the substrate drug because it is in first-line regimen of treatment of HIV/AIDS in South Africa, and also has been reported to be a substrate for the specific CYP isozymes, 3A4 and 2B6, in common with APs metabolic involvement with 3A4. A high performance liquid chromatography method with ultra-violet detection (HPLC-UV) for the quantitative determination of EFV in plasma was developed and successfully validated according to international standards with good reproducibility, accuracy, recovery, linear response and requisite sensitivity. The preparation of the plasma samples for analysis was effected by using a simple and rapid precipitation method, and the mobile phase consisted of readily available solvents. EFV in plasma samples was found to be stable under the relevant storage conditions studied. The oral dose of AP, administered as a freshly prepared traditional decoction, was standardised based on the hypoxoside content, and the quality of all the AP decoctions was analysed immediately prior to administration, using a validated HPLC-UV method. A single dose, two-phase sequential study was conducted over a period of 31 days in 10 healthy volunteers. The clinical study was approved by the Rhodes University Ethical Standards Committee, and all the participants agreed to the conditions of the study by giving their informed consent. On day 1 of the study, human subjects were administered a 600 mg EFV tablet and blood samples were collected before dosing and at various intervals over a period of 48 hr post dosing. From day 16, a traditionally prepared AP decoction was administered daily at a standardized dose of 15 mg/kg/day per subject until day 30. On day 29, volunteers were administered a single 600 mg dose of EFV as was done on day 1. Plasma samples were harvested immediately after blood sample collection and frozen at -80 ºC until assayed. Geometric mean ratios of relevant pharmacokinetic parameters, Cmax (maximum plasma concentration achieved following dosing) and AUC0-48 (area under the curve of a plot of drug plasma concentrations versus time representing the extent of absorption) of EFV before and after co-administration of 14 successive daily doses of AP were compared and evaluated to determine whether an interaction had occurred. All subjects completed the study and the geometric mean ratios of Cmax and AUC0-48 were 97.30 and 102.82 with corresponding 90% confidence intervals (CIs) of 78.81-120.14% and 89.04-118.80%, respectively. Whereas the acceptance criteria for the ratios of the AUCs fell within the preset 90% CIs indicating no interaction, the Cmax ratios fell outside the limits. Although the protocol was developed in accordance with the United States of America Food & Drug Administration’s Guidance for Drug Interactions, a priori stating that both criteria need to fall within the acceptance limits to indicate no interaction, an argument is presented to waive the Cmax requirement for the declaration of an interaction. As a result, the pharmacokinetic data generated during this study indicated that the effect of AP on the pharmacokinetics of EFV is not clinically significant. Hence, co-administration of AP is unlikely to affect the clinical use of EFV. In summary the objectives of this project were: 1. To develop and validate a suitable HPLC-UV method for the quantitative determination of EFV in plasma. 2. To perform a mini-validation of the determination of hypoxoside for use as a marker in the quality control and standardisation of AP decoctions. 3. To conduct a clinical interaction study in order to determine whether AP affects the pharmacokinetics of EFV following concurrent administration. 4. To apply the validated HPLC-UV method to determine plasma concentrations of EFV in plasma of human subjects. 5. To use appropriate statistical methods and treatments such as a non-compartmental pharmacokinetic analysis to determine the occurrence of an interaction.

Although the protocol was developed in accordance with the United States of America Food & Drug Administration’s Guidance for Drug Interactions, a priori stating that both criteria need to fall within the acceptance limits to indicate no interaction, an argument is presented to waive the Cmax requirement for the declaration of an interaction. As a result, the pharmacokinetic data generated during this study indicated that the effect of AP on the pharmacokinetics of EFV is not clinically significant. Hence, co-administration of AP is unlikely to affect the clinical use of EFV. In summary the objectives of this project were: 1. To develop and validate a suitable HPLC-UV method for the quantitative determination of EFV in plasma. 2. To perform a mini-validation of the determination of hypoxoside for use as a marker in the quality control and standardisation of AP decoctions. 3. To conduct a clinical interaction study in order to determine whether AP affects the pharmacokinetics of EFV following concurrent administration. 4. To apply the validated HPLC-UV method to determine plasma concentrations of EFV in plasma of human subjects. 5. To use appropriate statistical methods and treatments such as a non-compartmental pharmacokinetic analysis to determine the occurrence of an interaction.
