- Description: Although Nurse Educators are aware of the advantages of simulation-based training, some still feel uncomfortable to use technology or lack the motivation to learn how to use the technology. The aging population of nurse educators cause frustration and anxiety. They struggle with how to include these tools, particularly in the light of faculty shortages. Nursing education programmes are increasingly adopting simulation in both undergraduate and graduate curricula. Scoping literature reviews show that nursing practice has changed in recent years, placing demands on nurse educators to utilise different approaches in education. The fact that nurse educators are an aging population needs to be taken into consideration and acknowledge that many of them did not grow up with computers and lag behind in technological skills. The aim of this study was to investigate the perceptions of nurse educators regarding the use of high-fidelity simulation in nursing education at a South African Private Nursing College in order to be able to determine why High-fidelity Simulators (HFS) have not yet been embraced by nurse educators and students. A national survey of nurse educators and clinical training specialists was completed with 128 participants; but only 79 completed the survey. In addition to background information, participants were questioned about their use of simulators. They were asked to complete the Technology Readiness Index. Information was also obtained regarding their perceptions of the use of HFS. Findings included indications that everyone is at the same level as far as technology readiness is concerned; this, however, does not play a large role in the use of HFS. This finding supports the educators’ need for training to adequately prepare them to use simulation equipment. Recommendations for further study include research to determine what other factors play a role in the use of HFS, studies to determine whether the benefits of HFS are superior to other teaching strategies warranting the time and financial commitment. The results of this study can be used as guidelines for other institutions to prepare their teaching staff for the use of HFS.

- Description: South Africa is experiencing a serious shortage of nurses, especially nursing sub-professionals. The Eastern Cape Province is among the provinces with highest percentage of vacancies for nurses in all nursing categories. Nursing shortage has compromised South African health care services as health services are mostly supported by this group of health professionals. As a result of this shortage, rural health services have for a long time depended on the nursing sub-professionals to perform basic nursing services. This category is however also decreasing, which makes it difficult for nursing professionals to cope with the amount of work. South African rural health centres put pressure on professional nurses to do some of the health care activities that are meant to be done by medical doctors. The aim of the study was to explore the role and value of nursing sub-professionals in the health care system as viewed by the nursing managers. A qualitative exploratory study was conducted to get the perceptions of nursing service managers and operational managers on the role and value of nursing sub-professionals in the health service. A purposive sample of 23 participants was selected and interviewed. Most of the participants viewed the retention of nursing sub-professionals as crucial in the health service system. The participants saw sub-professionals as playing a vital role in the health services as the latter have a scope of practice that enables them to work independently. The reasons they put forth in support of their retention include reduction of litigations, easing the work load of professional nurses, sometimes performing non-nursing duties during crisis periods, reduction in the waiting time for patients/clients, and enabling professional nurses to perform more sophisticated professional duties which include management. Few managers viewed the existence of sub-professional nurses as increasing the work of nursing professionals. They felt that nursing sub-professionals worked under the supervision of nursing professionals. This, according to them, resulted in more work for nursing professionals who had to check and/or repeat what had been done in the name of supervision.

- Description: The National Health Insurance is a relatively new concept in South Africa currently being piloted to ensure that all citizens have access to quality and affordable health care regardless of their socio-economic status. This study was prompted by concerns regarding the introduction of the NHI and its implications on the South African health system. Therefore it seeks to determine the professional nurses concerns about the introduction of the NHI in a private hospital in Gauteng and to describe recommendations based on these perceptions. This study used a qualitative, exploratory and descriptive design. Data was collected using a semi-structured individual interview schedule. The sample was purposive consisting of professional nurses employed in a private hospital in Gauteng. Thematic data saturation determined the number of professional nurses interviewed. Data analysis was done with the aid of Creswell’s theory (2014:1996). Ethical considerations were observed and trustworthiness maintained. The results of the study outlined that professional nurse’s perception about the NHI is centred on equal distribution of health services to benefit all South Africans. However, concerns were based on its financial implications for those mandated to pay towards the fund. The feasibility of its implementation in the midst of staff shortage, inadequate resources and its impact on the public health sector was seen as a major challenge. The notion of a joint effort between public and private health sector in creating one health system was anticipated by most participants. The NHI implementation raised concerns about the impact it will have on the private sectors viability in the future. Professional nurse’s non-involvement in policy making, poor communication, lack of transparency, concerns about governance and management were perceived to be stumbling blocks towards efficient and effective implementation of the NHI.

- Description: Life-support treatment is regarded as the support of vital functions of respiration and circulation such as mechanical ventilation and inotropic support, and life-sustaining therapy which incorporate therapies such as artificial hydration, nutrition and haemodialysis. Life-support treatment is rendered to critically ill patients within the intensive care units. However, when treatment options are maximised, and the patient’s condition is unchanged, a decision is often made to withdraw treatment. Professional nurses are usually involved in the process of withdrawal of life-support treatment as they care for this population of patients. The study followed a qualitative, explorative, descriptive and contextual research paradigm in order to explore and describe the perceptions of professional nurses with regard to the process of withdrawing life-support treatment in a private intensive care unit. Data was collected by means of interviews, which were transcribed according to Tesch’s method of analysis. Field notes were used to supplement the data findings. Based on the data collected, it is clear that professional nurses experience difficulties when performing withdrawal of life-support treatment. There are a number of communication concerns which need to be addressed and suggestions were also made by the interview participants regarding these concerns. The study makes recommendations to assist professional nurses with the process of withdrawing life-support treatment in a private intensive care unit. The findings of the study will be disseminated to the relevant hospital and unit managers. Ethical principles were maintained throughout the study by adhering to the principles of privacy, confidentiality, anonymity and beneficence.

- Description: Literature on generational theory has paid much attention to the differences in values and work ethics between employees from different generational cohorts, but more specifically between managers and the Millennial Generation. These differences in values and ethics affect the way in which multigenerational employees perceive one another, which often leads to conflict and demotivation in the workplace. In an attempt to explore the perceptions of managers of the Emergency Medical Services regarding the management of the Millennial Generation, the researcher undertook a qualitative, descriptive, exploratory and contextual study. Data were gathered through 11 in-depth semi-structured interviews with managers of provincial Emergency Medical Services in the Nelson Mandela Bay Health District. Data were analysed by using Tesch’s steps in data analysis. During the data analysis, the following four main themes emerged: The employees from the Millennial Generation lacked the discipline required for working in emergency services. The employees from the Millennial Generation had up-to-date knowledge, but had little practical experience. Specific attributes of the Millennial Generation were identified. The managers indicated that the employees from the Millennial Generation were in need of management support. The researcher found that many of the participants’ perceptions were inaccurate and influenced by preconceived generational stereotypes and prejudices. The research ended with recommendations, which should assist managers to manage employees from the Millennial Generation in the Emergency Medical Services more effectively. Recommendations were also made for further research. It is acknowledged that the research study had limitations, which included the fact that the data were only collected from one of the eight districts in the Eastern Cape and that the study did not include the private ambulance services in the Nelson Mandela Bay Health District.

- Description: The introduction of Self-Service Checkout Systems (SSCOs) has disrupted and continues to transform grocery retail businesses particularly in the age of the 4th Industrial Revolution (4IR), which is characterised by the pervasive presence of technological innovation in multiple sectors. SSCOs have over the years made significant in-roads in the grocery retail sector, particularly in the developed world with few exceptions of implementation in the developing world. Self Service Technologies (SST) have been used across various industries for many years in order to improve customer experience, or to address business priorities, or both. SSCOs (an SST technology) within grocery retail, have been purported to increase customer convenience, efficiency and bolster the competitive advantage of various businesses, amongst other benefits. The benefits and opportunities, risk and challenges, impact on business, perceptions of customers and customer acceptance of SSCOs have been and continue to be widely studied within the retail sector of the developed and in some parts of the developing world. The understanding and implementation of SSCOs in developing countries in general and South Africa in particular are at an embryonic stage. Questions of implementation, acceptance and adoption of SSCOs in South Africa are under-researched and nascent. However, despite their vagueness within the South African grocery retail sector, there are instances where SSCOs have been implemented in South Africa. Taking into account the fact that the South African grocery retail sector is heavily influenced by the adoption of technological innovation and follows the trends from the developed world, it is only a matter of time before SSCOs become mainstream technologies in South Africa. This is more so particularly in the era of the 4IR where technology is increasingly transforming entire industries. Against this backdrop, this study addresses the question of acceptance of SSCOs within the grocery retail sector in South Africa. Whilst grocery retailers consider whether to implement SSCOs, they have to ask themselves a number of pertinent questions, not in the least whether customers would be willing to adopt the use of the technology. It is in light of this acceptability of SSCOs that the research engaged grocery retailers to investigate their perception regarding the factors that affect the acceptance of SSCOs within the South African grocery retail sector. This study followed a qualitative research design. Participants were management and owners of the SPAR retail group in South Africa. Twenty-three participants took part in the study and seventeen participant’s responses were accepted for analysis. An online open ended vi | P a g e questionnaire was used to collect data from participants and a thematic analysis was applied to the collected data in order to search for themes within the data. The Technology Acceptance Model (TAM) and the Theory of Diffusion of Innovation (DOI) were used as frameworks to interpret the study findings. The results of the study indicate that the South African grocery retail sector is innovative and implements various technologies. Further, a number of grocery retailers are actively considering the implementation of SSCOs. A number of factors that promote that acceptance of SSCOs were identified by the study, for example, customer experience at checkout, which includes convenience and efficiency and business profitability. On the other hand, there are factors that hinder the acceptance of SSCOs, which include factors like loss of employment, poor infrastructure and the cost of implementation amongst others. Based on the results of the study a theoretical framework was developed, which was used to give recommendations to the grocery retail sector in order to offer guidance regarding the implementation of SSCOs in South Africa. Finally, areas and orientations of future research were identified. This study contributes to the literature on SSCOs in South Africa in particular and the developing world in general. In addition, this study contributes to academic theory and business practise by applying the Diffusion of Innovation Theory and the Technology Acceptance Model to a unique context in a new way, i.e. SSCOs in the grocery retail sector in South Africa. The limitation of the study is that the participants were from one grocery retail organisation and thus probably represent a certain grocery retail outlook based on the culture of the organisation. Future research would need to be more inclusive and have a heterogeneous research sample in order to be more reflective of multiple organisations and cultures within the grocery retail sector in South Africa. The introduction of SSCOs in South Africa will transform the grocery retail sector. The understanding of the technology and its acceptance within the sector is critical to help grocery retailers develop strategies to drive business growth, improve customer experience and capitalise on the direction of transformation that technology brings to the sector. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The purpose of this study is to determine the perception of Management and Staff at Goedgedacht Trust regarding Social Dialogue and Codetermination. Goedgedacht Trust is a non-profit organisation that has been in existence for 27 (twenty-seven) years. The organisation pursues its mandate to alleviate poverty in the rural communities of the Swartland area in the Western Cape. Funders of Goedgedacht Trust have undertaken 2 (two) impact studies, the reports of which constitute the impetus for this study. The study utilised a qualitative research methodology and research explores the field of Organisational Behaviour, General and Human Resource Management in the context of a non-profit organisation. It is submitted that the findings emanating from this paper are equally applicable to organisations with a profit driven agenda. In terms of the findings, it is submitted that the overriding perception of both Staff and Management was that Social Dialogue and Codetermination were practiced to a certain degree, albeit on an ad hoc basis such that it did not result in any significant value to the organisation’s success at the time of writing. As set out more fully herein, a concerted effort is required to make Social Dialogue and Codetermination a strategic objective of an organisation, which objective should be pursued and the outcomes measured (with shortcomings appropriately addressed) for continuous improvement. Following this study, it is submitted that for there to be impactful Social Dialogue and Codetermination, the organisation in question must foster an environment that encourages vertical communication throughout, undertakes a cohesive and transformative approach to management and an overall collaborative culture at all levels. The study also found that the support factors to Social Dialogue and Codetermination is an engaging, collaborative culture with communication that is open throughout the organisation. Furthermore, in addition to inter alia an inclusive and engaging culture, Social Dialogue and Codetermination requires a well-defined Human Resource Management and a Conflict Management system, which should be transparent, trustworthy and consistent in its application. This study lays the foundation for further research on the effectiveness of the proposed conflict management system and whether conflict management has produced a saving on the real cost of conflict at Goedgedacht Trust. , Thesis (MPhil) -- Faculty of Humanities, 2021

This study lays the foundation for further research on the effectiveness of the proposed conflict management system and whether conflict management has produced a saving on the real cost of conflict at Goedgedacht Trust. , Thesis (MPhil) -- Faculty of Humanities, 2021

- Description: Mathematical Literacy is a compulsory subject at the Further Education and Training (FET) level in South Africa. All learners who do not select Mathematics are required to study Mathematical Literacy as their numeracy subject in Grade 10, the first year of studying at the FET level. This requirement coincided with the educational reforms which were introduced in South Africa after democracy was attained in1994. Mathematical Literacy was introduced in Grade 10 in 2008, in Grade 11 in 2009 and in Grade 12 in 2010. Matriculants in 2012 comprised the cohort who wrote the Mathematical Literacy examination for the first time in South African history. Although 4 years have passed since the introduction of Mathematical Literacy in Grade 12, many teachers are still not sufficiently competent enough to teach the subject. This fact has been demonstrated quite conclusively in the matriculation results of the past 4 years. The failure to teach the subject satisfactorily is the result of poor knowledge of the content of the courses, insufficient teaching materials and incorrect teaching methods. This study has focused on uncovering the perceptions of teachers of the teaching of Mathematical Literacy and on how best to support and assist teachers in order to improve their knowledge of the content of their courses, to improve the methods of teaching the subject and to provide sufficient resources to support both teaching and learning. The study is also aimed to draw the attention of the Department of Education (DoE) to the need to provide better training in order to develop the competency of teachers in the subject and to overcome the lack of resources through developing innovative ways of teaching it. A qualitative approach was adopted in order to conduct the research, as it aims to provide an explicit rendering of the structure, order and broad patterns pertaining to the teaching of the subject from a group of participants. Qualitative research is best suited to studies of this sort, as it provides the means to conduct an in-depth investigation of the thoughts, beliefs, attitudes and responses of teachers concerning the teaching of Mathematical Literacy at the FET level. The research was conducted in 6 FET schools in the East London Education District. Six teachers of Mathematics and Mathematical Literacy in Grades 10, 11 and 12 were selected to comprise the research sample for the study. Semi-structured questions were used to collect the data. The research study established that educators have divergent perceptions and beliefs concerning the teaching of Mathematical Literacy at the FET level. The study was also able to identify the problems, obstacles and difficulties encountered by the teachers in their attempts to teach the subject and the trends which emerged during the conducting of the research.

- Description: The aim of this study was to explore the perceptions of RDP beneficiaries on the extent to which the RDP housing project meets their housing needs in South Africa through a case study of Golf Course Estate in Alice Town with the following specific objectives; to assess the extent to which the Alice Golf Course housing project has achieved the RDP programme objectives; to establish beneficiaries‟ perceptions on the extent the RDP Alice Golf Course houses meet their needs; and to explore the level of satisfaction on the RDP houses by beneficiaries. This study utilized triangulation of both quantitative and qualitative methodologies with qualitative as the dominant approach while quantitative was less dominant. The qualitative design took the form of a case study while the quantitative took the form of mini survey. The study sampled 72 participants from the study population. The study utilized an interview guide and a questionnaire as instruments of data collection. The findings indicated that the gender representation of the beneficiaries was skewed. This is because there were more females heading the houses than males; unemployment was also high; most participants were unmarried and most were adults. This study also discovered that most people residing in these houses are not the real owners who were allocated the houses. There were qualitative problems associated with the components of these houses such as poor roofing, doors, windows, floors and walls. Service delivery complaints were based on inadequate access to clean water, small size and spacing of the RDP house. Security was also a challenge because all the houses did not have street lights and the roads were very bad. Though it is commendable that drainage and sewer facilities are available, but they are not serving their purpose since there is no water in these houses. The findings also indicated that there were discrepancies in allocation of the houses; pervasiveness of social ills; inadequate consultative meetings between the RDP Administrator or social worker and the beneficiaries; as well as the pervasiveness of HIV/AIDS among other issues. This researcher recommended that the government needs to promote economic empowerment to deal with unemployment; to improve the quality of the material building the houses; improvement on service delivery gaps; to beef up infrastructure; renovation and revamping of current houses; to establish commissions of inquiry to deal with corruption; to honour and monitor waiting lists. Partnership with other stakeholders was also critical, in addressing access to social services and helps deal with social ills and run behaviour modification campaigns. This researcher also recommended that there is a need to carry out further research on the role played by the municipalities in the RDP housing project as well as conducting a purely qualitative research to further explore the perceptions of other stakeholders, NGOs, traditional leaders, church leaders, and police on the implementation of the housing project. This researcher advises that such a research could be carried out through focus group discussions and also since this study was bound by a case study it is also necessary for similar research to be carried out in different places in South Africa. , Thesis (MA) -- Faculty Social Sciences and Humanities, 2013

- Description: This contextual analysis is concerned with the study of the Basic Education Teacher's Diploma In-service Curriculum. It is based on the following assumptions: firstly, that the BETD (Inset and Preset) represents the Namibian Educational Reform in the realm of Teacher Education. Secondly, it is assumed that the BETD as a vehicle for reform in Teacher Education should yield teachers who are capable of change and development. Based on the above-mentioned assumptions, this analysis examines this Teacher Education course/programme against some criteria pertinent to its philosophy. A critical analysis of its curriculum in terms of some core subjects, as well as its practical implementation, will form the basis of this scrutiny. Secondary to the above, this analysis also intends to reflect this sociohistoric and economic context in which the BETD has been designed. An underlying motive in this analysis is to study the dynamics between the philosophy, which represents the heart and intention of the Namibian educational reform on the one hand and implementation which in turn delivers the end product or final outcome of the course on the other hand. This analysis should also fit into the current debate between conservatives who claim that the BETD lacks content and is therefore inferior, and those who claim that the course adequately prepares teachers for the needs of Basic Education.

- Description: In South Africa, the issue of lack of black pilot skills is a most talked about topic in commercial airlines. Airlines need to find the right set of skills and attitude to operate safely and successfully. Airline safety remains a topic of discussion, therefore airlines need ensure robustness of their selection processes. There are many requirements that a person has to meet before s/he can be offered a first officer job at an airline. The majority of the pilots in South Africa are white males. The study aimed to determine if there are statistically significant differences in cognitive ability test results between Black and White applicants for pilot positions with a South Africa airline. The test battery included a verbal reasoning test, numerical reasoning test, visual thinking, abstract reasoning test, spatial reasoning test, short term memory test, monitoring ability test, hand-eye coordination, sense of orientation test, reactivity test, and a multi-tasking test. The data were extracted with permission from a database maintained on behalf of the airline by an online test provider and subjected to a statistical analysis using measures of central tendency, and spread, in order to report on the significance of the differences between the groups. There is strong evidence that the White group performed better than the Black group on the majority of the tests. It is recommended that further research is done in order to determine the causes of these differences. A comparative study of results on other airlines’ recruitment selection tests and an exploratory study of the impact of socio-economic factors, education quality and language on cognitive ability tests are recommended.

The performance and preference of a specialist herbivore, Catorhintha schaffneri (Coreidae), on its polytypic host plant, Pereskia aculeata (Cactaceae)

- Description: Plant species moved beyond their natural ranges may be liberated into enemy-free spaces, where they increase resource allocation to fitness, rather than defence against natural enemies, and become invasive as suggested by the Evolution of Increased Competitive Ability (EICA) Hypothesis. Several cacti are notable invaders and are targeted for biological control. The leafy cactus, Pereskia aculeata Miller, introduced into South Africa from South America, has become a target for biological control after becoming invasive. The absence of natural enemies of P. aculeata in the introduced range may be the reason for its invasiveness. This thesis seeks to investigate the role of the evolution of increased competitive ability (enemy release) as the probable driver of P. aculeata’s success, and ascertain how the plant’s intraspecific variation influences the impact, fitness of, and preference by its biological control agent, Catorhintha schaffneri Brailovsky and Garcia (Coreidae), in South Africa. Enemy release and evolution of traits in P. aculeata were examined by quantifying plant growth parameters of fifteen genotypes of P. aculeata from both the native and invaded distribution of the plant. Ten genotypes of P. aculeata were used in testing the effect of agent herbivory (impact and damage) under similar conditions. These studies indicated that most invaded-range genotypes were more vigorous than the native genotypes. Rapid growth may account for the quick access of invasive genotypes of P. aculeata to tree canopies. Catorhintha schaffneri damage varied between genotypes but differences in the damage and impact from the agent could not be explained by whether the plant originated in the introduced or native distribution. In sum, while the growth of the invasive genotypes largely conforms to the EICA hypothesis, the impact of C. schaffneri did not support the hypothesis. The influence of host variation in P. aculeata on the fitness of C. schaffneri within the context of local adaptation to plant genotypes from different localities was tested using agent survival, stage-specific and total developmental time, and the extent of damage to ten host genotypes. Maw’s Host Suitability Index (HIS) and Dobie’s Susceptibility Index (DSI) showed the preference by and performance of C. schaffneri on the different genotypes of the plant. Catorhintha schaffneri survived to the adult stage on 70% of genotypes tested. Evidence consistent with the assumption that C. schaffneri would be fitter on the native genotypes than the invasive genotypes due to local adaptation was not found. In addition, there was no evidence in support of fitter agents on the invasive genotypes than on the native genotypes as proposed by EICA hypothesis. Catorhintha schaffneri developed equally well on the invasive genotypes of P. aculeata as on the native genotypes. To establish whether host variation would affect diet selection by C. schaffneri, both nymphs and adults were examined in paired-choice and multiple-choice trials. The nymphs and adults chose their hosts regardless of host genotype differences. The agent may be good at selecting good succulent shoots from bad shoots, but is incapable of distinguishing a good host genotype from a poorer one. This thesis shows, therefore, that P. aculeata and its array of genotypes in South Africa could be effectively controlled by C. schaffneri, as it has the potential to suitably utilise and impact the different genotypes of the weed in South Africa with neither any demonstrable preference nor local adaptation for the native genotypes. Consequently, the use of C. schaffneri, as a biological control agent in the weed biological control programme of P. aculeata remains promising, as the agent is insensitive to the intraspecific variation of the invasive host plants.

The reflector surfaces of the Cassegrain antenna were surveyed and the surface errors minimised, while the magnitude of thermal and gravitational defomations was calculated. The design and operation of the microwave front end has been improved, and the mixer performance characterised. The continuum and spectral line receivers and their sensitivity are described. The aperture efficiency, which has been raised from 0,47 to 0,57, was deduced from solar and lunar observations and atmospheric attenuation measurements. The antenna beam pattern was also obtained from the observations, with the aid of a computer program, and is compared to that predicted for the telescope.

- Description: Research has shown that Attention Deficit Hyperactivity Disorder (ADHD) is one of the commonest neurodevelopmental disorders which has a negative impact on a child. However, to date limited research has been conducted on learners, and specifically those learners with ADHD, within a National Education stream. Furthermore, running concurrently with this are new developments in education in South Africa. An inclusive educational policy favours the incorporation of all children into a mainstream scholastic setting, regardless of their diverse needs. In addition to educational changes for children with ADHD, many parents are presently unable to afford the medication commonly used to treat the disorder, resulting in both parents and teachers having to manage these children with limited professional support. It is widely accepted that early assessment and intervention are necessary in order to maximise a child’s potential. For this reason, the primary aim of this study was to explore and describe the developmental profile of children with ADHD on the Griffiths Mental Development Scales-Extended Revised (GMDS-ER). Further aims were to compare the performance of the clinical sample to a normal South African sample. In order to achieve these aims, a quantitative, exploratory-descriptive research design was employed. The sample (N = 38) of ADHD were selected by means of a non-probability, purposive sampling procedure, from various pre-school and primary schools in the Nelson Mandela Metropole. The normal sample (N = 38) was drawn from an existing database created during the revision of the Scales. Information was collated using the Conners 39 Item Teacher Rating Scale, biographical data, as well as the results of an assessment from the GMDS-ER. In this study the general performance of the ADHD sample on the GMDS-ER was found to be above average. Furthermore the performance of these children on the six Subscales of the GMDS-ER ranged from average to superior, with the poorest performance being on the Eye and Hand Co-ordination Subscale, and the best performance being on the Performance Subscale. Significant differences between the ADHD and normal sample were found on the General Quotient (GQ) as well as three of the six Subscales, namely, the Hearing and Speech, Eye and Hand Co-ordination and Performance Subscales. Generally, the results of the study suggest that a specific developmental profile for children with ADHD exists. Additionally, the study highlighted the success with which the GMDS-ER can be utilised on a specific clinical population.

Furthermore, running concurrently with this are new developments in education in South Africa. An inclusive educational policy favours the incorporation of all children into a mainstream scholastic setting, regardless of their diverse needs. In addition to educational changes for children with ADHD, many parents are presently unable to afford the medication commonly used to treat the disorder, resulting in both parents and teachers having to manage these children with limited professional support. It is widely accepted that early assessment and intervention are necessary in order to maximise a child’s potential. For this reason, the primary aim of this study was to explore and describe the developmental profile of children with ADHD on the Griffiths Mental Development Scales-Extended Revised (GMDS-ER). Further aims were to compare the performance of the clinical sample to a normal South African sample. In order to achieve these aims, a quantitative, exploratory-descriptive research design was employed. The sample (N = 38) of ADHD were selected by means of a non-probability, purposive sampling procedure, from various pre-school and primary schools in the Nelson Mandela Metropole. The normal sample (N = 38) was drawn from an existing database created during the revision of the Scales. Information was collated using the Conners 39 Item Teacher Rating Scale, biographical data, as well as the results of an assessment from the GMDS-ER. In this study the general performance of the ADHD sample on the GMDS-ER was found to be above average. Furthermore the performance of these children on the six Subscales of the GMDS-ER ranged from average to superior, with the poorest performance being on the Eye and Hand Co-ordination Subscale, and the best performance being on the Performance Subscale. Significant differences between the ADHD and normal sample were found on the General Quotient (GQ) as well as three of the six Subscales, namely, the Hearing and Speech, Eye and Hand Co-ordination and Performance Subscales. Generally, the results of the study suggest that a specific developmental profile for children with ADHD exists. Additionally, the study highlighted the success with which the GMDS-ER can be utilised on a specific clinical population.

- Description: Despite a widespread perception that the number of children coming to clinical attention with Autism Spectrum Disorders has greatly increased, limited South African Research has been conducted on children with Autism. Thus a need exists to accumulate knowledge about the cognitive, psychological and personalsocial growth of children diagnosed with Autism. This study is aimed at exploring the performance of children with Autism between the ages of 7 years (from 72 months) and 8 years (to 95.9 months), in South Africa (SA), utilising the Revised Extended Griffiths Scales of Mental Development (GSMD). The sample comprised an experimental group of 30 children with Autism from four schools for Specialised Education for learners with Autism in SA, and a control group comprised of 30 “normal” children, where normalcy can be broadly defined as “an absence of any sensory, physical or mental handicap”. The six areas of general development assessed included Locomotor, Personal- Social, Language, Eye and Hand co-ordination, Performance, and Practical Reasoning. A non-probability, purposive sampling method was applied. The major findings of the present study were as follows: (i) Children with Autism (years 7 & 8) showed a characteristic cognitive profile when tested with the revised Extended Griffiths Scales. Their performance indicates lower performance on Subcales B, C and F than on the other Subscales. (ii) Some children with Autism experienced major fall-outs, whereas others were slightly below average. The general performance of children with Autism was, however, in the range “cognitively impaired”. (iii) There was significant difference between the Autistic sample and the normal sample on the GQ. xiv In view of the findings, it is recommended that the results of the study, which focused on the children’s areas of developmental weakness, be widely disseminated. This could facilitate the development of therapeutic programmes, so as to allow for appropriate stimulation for children with Autism.

- Description: In this unique time of nation building in South Africa, education is seen as the key foundation stone to prosperity and development. However, despite a decade of restructuring, many differing groups of children still do not receive the quality of education they deserve. Amongst those are children with special needs, including those who have a hearing impairment. These children are the focus of the present study. It is a widely accepted principle that early assessment and intervention is necessary to maximise a child’s potential. It is for this reason that the global aim of this study was to explore and describe the developmental profile of hearing impaired children on the Revised Extended Griffiths Scales. Further aims were to compare the performance of the clinical sample to a normal South African sample. A quantitative, exploratory-descriptive research design was employed. The sample of hearing impaired children (N = 58), between the ages of 36 and 95 months, attended the Carel du Toit Pre-School in the Western Cape, South Africa and were obtained by means of a non-probability, purposive sampling procedure. The normal sample (N = 58) was drawn from an existing database created for the revision of the Scales. Information was collated using clinical files, biographical data as well as the results of an assessment on the Revised Extended Griffiths Scales. The major findings of the study are summarised below. The general performance of the hearing impaired sample on the Revised Extended Griffiths Scales was average. The performance of the children on the six subscales ranged from below average to average, with major fall-outs occurring on the Hearing and Speech and Practical Reasoning Subscales. The normal sample performed significantly better than the hearing impaired sample on all of the subscales of the measure. However, significant differences were found on four of the six subscales, namely, the Locomotor, Personal-Social, Hearing and Speech and Practical Reasoning Subscales. Generally, the results of the current study suggest that a specific developmental profile is obtained for hearing impaired children. In addition, this study has highlighted the success with which the Revised Extended Griffiths Scales can be utilised on a hearing impaired population.

- Description: Access to water services in South Africa still remains a dream for most people, especially those who live in remote areas. The poverty stricken communities of the former Transkei in the Eastern Cape are in need of water and sanitation services. The findings of the study reveal that most community members are dissatisfied with the water service delivery. During an interview with ward 6 residents who reside in an urban area of the OR Tambo District Municipality (ORTDM), they revealed that pipe bursting is one of the main causes why from time to time they do not have water. The other factor is when there is no electricity; the water system depends on the availability of electricity. The South African local government has been mandated to consult with its citizenry in respect of the processes relating to water service delivery. South Africa has developed a wide range of legislation that ensures community consultation on a continuous basis with regard to how water services should be delivered. It is the community‟s right to be consulted and to give input on issues that directly affect them. The researcher used a qualitative research method since it would provide the reader with more insight into how water services are delivered in the ORTDM. Both community members and municipal officials were interviewed. A number of findings have been made during the research. Some community members are of the view that constant community consultation could reduce service delivery protests. Political intervention needs to be made by the leadership with regard to service delivery and more resources need to be committed toward those processes. This study was conducted from April 2012 to November 2012 and was aimed at assessing the performance of OR Tambo District Municipality regarding water service delivery. According to OR Tambo DM (2011/12: 3), the communities through the consultation processes conducted throughout five (5) local municipalities made it clear that ensuring increased access to water and sanitation services is still the main priority.

- Description: The South African context necessitates developmental assessment measures with particular characteristics. A critical examination of a variety of potential measures indicates that there are very few measures available to meet these specific needs. The GMDS-ER is judged to be one such measure. This study explores the performance of South African children aged 4 to 7 years of age as it relates to that of British children (from the standardisation sample). The samples consisted of normal South African (n=129) and British (n=161) children, where normalcy refers to the absence of sensory, physical, or mental handicap. The study was done in an attempt to explore the suitability of using the GMDS-ER in the South African context. More specifically, the following two aims were pursued: 1. To explore and describe the general development of each of four year groups of a sample of British and South African children by utilising the general developmental quotient of the GMDS-ER 2. To explore and describe the comparative developmental profiles of each of the four year groups of a sample of British and South African children across the six developmental areas represented by the subscales of the GMDS-ER. Descriptive statistics and simple t-tests were used to accomplish Aim 1 and Hotellings T2 tests were mainly used in order to accomplish Aim 2. The major findings of the present study were as follows: 1. South African and British children’s overall performances (as measured by the GMDS-ER GQ) are similar. A great deal of variability exists between the GMDS-ER profiles of normal South African and British children (i.e., when individual subscales and year groups are considered). 3. In general, South African children performed better on the Locomotor and Personal-Social Subscales, while British children performed better on the Language and Practical Reasoning Subscales. Performance on the Eye and Hand Coordination Subscale was similar for the two samples and on the Performance Subscale performance was too variable to come to any general conclusions. In view of the findings, caution with regard to the use of the British-based norms in the South African context is recommended. Recommendations are made for the use of the GMDS-ER to help with the identification of specific classes of disorders in the South African context. Further investigation into the applicability of the GMDS-ER for South African use as well as the establishment of South African norms are final recommendations.

This psychobiography reviews the life of Steven Paul Jobs (1955-2011), United States information technology intrepreneur and inventor. This study employs a qualitative, case study design. The researcher preferred a specific individual, therefore this study entails a non- probability, purposive sampling procedure. The data collection consists of primary and secondary sources. Data analysis was conducted according to Alexander’s (1988) model, as well as Miles and Huberman’s (1994) approach. The research conducted was done in an ethical manner. The primary aim of this study is to describe and interpret Jobs’ personal development through the application of tevinson et al.’s human development framework. Jobs was born, and soon after birth, given up for adoption. At the age of twenty-one, he and his friend, Steve Wozniak, invented Apple Computers. Jobs was known as an entrepreneur, innovator and genius, and was recognised as a pioneer in the information technology world. Regardless of personal and business disappointments, he designed successful products, generated enormous profits and led Apple to become the world’s most valuable and leading company. Through exploring Jobs’ life, a holistic overview of his personal development was obtained.
