- Description: This study is about factors affecting the effectiveness of parental involvement in their children’s education. This chapter focuses on the background to the study, statement of the problem, research questions, delimitation and limitations of the study and definitions of terms used in the context of the study. The education system during the apartheid era did not encourage effective involvement of stakeholders in schools. The achievement of democracy in South Africa has consigned to history the past system of Education which was based on racial inequality and segregation whereas this country requires a new national system for schools which will redress past injustices in educational provision, provide an education of progressively high quality for all learners (South African Schools Act (SASA) 84 of 1996). One of the factors which influence the success of a school system is the involvement of its stakeholders (SASA 84 of 1996). The school stakeholders are parents, educators, the learners, the community and the department of education officials. This means that these stakeholders should work together. According to SASA, a parent is the person legally entitled to the custody of a learner or a person who undertakes to fulfill the obligations of a person towards the learner’s education at school. Parental involvement is described as the willingness and active participation of parents in a wide range of school and home-based activities related to their children’s education. Literally, parental involvement is a dynamic process whereby teachers and parents work together for the ultimate benefit of the child. The SASA emphasizes that the role of parents in the education of their children is a vital support source of learning.

- Description: The objective of this research study was to describe and explore challenges faced by professional nurses in implementing six ministerial priority standards of care in selected units of an identified institution in O.R. Tambo region. Nurses are trained and employed to provide nursing care to patients according to scope of practice set by their statutory body (South African Nursing Council). Setting of standards forms part of quality improvement in nursing care and standards need to be monitored and evaluated (Muller 2006:206). In South Africa, the Minister of Health has identified six priority areas to fast-track improvement and ensure quality in health services. These priority areas are as follows: attitudes and values of health workers, cleanliness of the facility, waiting times, patient safety and security, infection prevention and control, and availability of medicines (National Health Plan: Strategic plan 2010/2013). Standard of nursing care in OR Tambo region according to available statistics, is lower than the expected ministerial standards, regardless of continued monitoring and evaluation. Staff attitudes is an ongoing problem, long queues, linen shortages, low standards of cleanliness as well as shortage of medication remain a challenge in health care institutions. This study is a qualitative, descriptive, exploratory, and contextual study that explored challenges faced by professional nurses in implementing the six ministerial priority standards of care. A purposive sampling of 10 professional nurses, meeting the selection criteria was utilised. In depth, semi structured interviews were used as a method of data collection. A digital voice recorder was used to record the interviews and consent from participants was obtained. Ethical considerations were adhered to. The interview question was: “What challenges are you facing in implementing expected standards of care with reference to the six ministerial priority standards of care?” Data was analysed using content thematic analysis approach. An independent coder with a Master’s degree and studying towards a doctorate helped with coding the results of the interviews. The Theory for Health Promotion in nursing as propounded by Botes (2006) was used to analyse the findings. The approach used was based on the external environment and its dimensions – social, physical and intellectual. v The findings of the research revealed the following themes: Lack of resources, demotivation of nurses, attitude of nurses, lack of monitoring and evaluation, environment and overcrowding, lack of patient safety, negligence, availability of policy and procedure manuals, and incompetency of health care professionals. The findings of this study revealed that nurses faced many challenges with regard to improving the standard of nursing care. According to Botes (2006), the purpose of nursing research is functional by nature, it provides guidelines for practice. Therefore in this study, a description of guidelines to improve nursing care has been done. Trustworthiness of the findings was ensured by utilising Lincoln and Guba’s model of trustworthiness. Limitations of the research are highlighted and recommendations for further and related studies are made.

The use of Afrikaans-English-Xhosa code switching and code mixing as a teaching strategy in the teaching of Afrikaans additional language in the secondary schools of the Transkei Region of the Eastern Cape Province (RSA)

- Description: This study seeks to report on the investigation into the need to use code switching as one of the language teaching strategies in the teaching and learning of Afrikaans as Additional Language in the FET band, in predominantly Xhosa-speaking environments in the Eastern Cape. The study was conducted in twelve secondary schools of the Transkei where Afrikaans is taught as an additional language. The sample of the study comprised the educators, the learners and the school managers of the twelve researched schools. The research was a case study of the selected schools. The participants were studied in their own environment and the data was collected by means of both the interviews and structured questionnaires. South Africa is a multilingual and multicultural country. This state of affairs calls for a serious re-evaluation of the existing teaching methodologies. Children acquire language skills in and outside the classroom in two different ways in multilingual societies. While children acquire proficiency in languages outside the classroom in a natural way, in the classroom they are constrained by rigid purist rules that compel them to learn languages in artificial ways. This manner of language acquisition in the predominantly Xhosa-speaking environments of the Eastern Cape, often goes hand in hand with code switching from source language to target language and vice versa. These children can be described as compound informal bilinguals (polyglots) as far as the indigenous languages are concerned since they acquire the indigenous languages from early childhood in natural settings. In the context of formal acquisition of European languages and Afrikaans in schools, they can be categorised as coordinate bilinguals. The linguistic disparities between classroom and natural acquisition practices were revealed in this investigation. In the classroom, code switching has two contradictory sides. On one hand code switching provides the teacher with ease of expression, confidence and satisfaction that the learners understand the lesson. Notwithstanding the dynamic attributes of code switching in the classroom, the learners are faced with the dilemma of having to avoid code switching as much as possible in the examinations since there is no room for code switching in the examinations. This investigation showed that despite the fact that non-mother tongue teaching is supposed to take place through the medium of the target language, both the teachers and the learners admitted that they code switch during Afrikaans classes and they perceive code switching as the best way to facilitate understanding. The findings of this study revealed that code switching was a natural and inevitable strategy in teaching an additional language. However, it also surfaced that some teachers resorted to using code switching because of their own lack of proficiency in the target language. Informed by the above findings, the study recommended that code switching be considered as one of the strategies to be used in the teaching and learning of Afrikaans as additional language. It was also recommended that learners be credited if they used code switching in the examinations since all respondents admitted that code switching was every-day practice in the classroom. This, however is to be done with extreme caution and with the sole purpose of assisting the learners achieve full mastery of the target language at the end of their learning career. Since this kind of exercise needs highly-skilled personnel, it was recommended that practising teachers be retrained and resource materials be expanded to all schools that offer Afrikaans as additional language. Although the arguments presented in this investigation do not reject the reality of the impeding effect code switching might have on the learning of an additional language, the study maintains that for purposes of mutual understanding, code switching is an enabling factor that impacts positively on the teaching-learning situation.

- Description: The policy on Inclusive Education acknowledges that all children can learn if they are given the necessary support. In order to achieve this goal, the Department of Education (DoE) introduced the establishment of SBSTs whose main function is to support teaching and learning in schools. This study used interpretive paradigm to explore perceptions of SBST about providing support to foundation phase (FP) teachers and to interpret what they said. Nonetheless, there seemed to be challenges on how to support learners experiencing barriers to learning among the members of the SBST. The aim of this study was to explore the perceptions of the School-Based Support Teams (SBSTs) about providing support to the foundation phase teachers in two Butterworth Primary Schools in the Eastern Cape. This study used the qualitative mode of inquiry and a case study as a research design. Semi-structured interviews using one on one, observations and document analysis were used to collect the data from the SBSTs about their perceptions of providing support to the FP teachers. Purposeful sampling was used where two mainstream primary schools were conveniently selected with six SBST participants from each school, making a total of six participants. Twelve SBST members were interviewed. Data were analysed and common themes emerged. The findings revealed that the SBSTs did not have enough knowledge and skills to support the FP teachers. Some of the challenges they cited included inadequate training, lack of communication, overcrowding and lack of support from the parents. In an attempt to alleviate the above-raised challenges, a model was proposed. These are some of the recommendations that resulted from the findings: all schools should have SBSTs, they should be composed of all the important stakeholders as proposed by the DoE, frequent SBST meetings should be held and further recommendations are made.

- Description: The purpose of this study was to investigate the implementation and management of workforce diversity among teachers at secondary schools in the Mthatha Education District with reference to national and international teachers. The literature reflects issues and theories concerning the implementation and management of workforce diversity in secondary schools. The study also shows the benefits of managing teacher diversity and the challenges in the implementation and management of workforce diversity among teachers in secondary schools. The population of the study comprised of all teachers in the fifty- six public secondary schools in the Mthatha Education District and the sample comprised of five principals, five deputy principals, five heads of departments and five international teachers on whom the case study was base to examine their views about the awareness, implementation and management of teacher diversity in the education system. This sample was drawn from five public senior secondary schools. The selection of the sample was done through the use of a purposive sampling technique. The sampling technique was used because it is not all public secondary schools in the Mthatha Education District where international teachers are found. This, therefore, allowed the researcher to select only those secondary schools at which international teachers were found. The researcher developed an open- ended interview schedule for the face-to-face in-depth interviews on the implementation and management of workforce diversity among teachers at secondary schools in the Mthatha Education District. Themes were drawn from the responses of the participants and analysed. The findings revealed that Principals, deputy principals, school management teams and teachers at all levels lacked the skills and knowledge in designing, implementing and managing teacher diversity policies in secondary schools. The findings revealed that local teachers were resistant and took a xenophobic stance towards the employment and promotions of International teachers in secondary schools. Lastly, Affirmative Action and Employment Equity Acts favour the local teachers and discriminate against the international teachers. Recommendations are made concerning the lack of awareness, skills and knowledge in designing and implementation of teacher diversity policies in secondary schools. Recommendations are also made concerning the Affirmative Action and Employment Equity Acts that influence the non recruitment and selection of international teachers.

- Description: Textiles have always been one of the essential materials for people and have a great variety of uses such as in clothing, agriculture, medical, automotive and aerospace applications. The sort of properties needed for any type of fabric basically depend on the structure of the fibre surface. Of many geometric attributes that can be used to describe the surface appearance of a fibre, yarn, or fabric sample, one of the more common is lustre. Mohair and wool fibre surface structure have been studied using optical microscopy and Atomic Force Microscopy (AFM). Optical microscopy was also used to take fibre diameter measurements. Another technique, goniophotometry, was used to make quantitative lustre measurements of mohair and wool fibres. The surface structure of mohair has got a faint pattern of scales where the scales are generally unpronounced or flat and relatively long. Wool has got a scaly surface structure where the scales overlap leading to interlocking of fibres. The scale configuration on the surface of mohair and wool fibres also differs. A qualitative connection between fibre lustre and the fibre surface structure was found. Because of its smooth surface relative to that of wool, mohair reflects a greater amount of incident light specularly whereas wool reflects most of the incident light diffusely. In general, mohair fibres have a higher lustre than wool due to its less prominent cuticle structure found on its surface. Furthermore, mohair fibres with the smallest diameters give an even higher lustre.

- Description: The purpose of this study was to investigate the causes and the ramifications of the political conflict in Ivory Coast from 2002 to 2009. A purposive sampling was used to select fourteen respondents. Qualitative methodology was used for the study. The data collection instruments were semi-structured interview questions, open-ended Semi-structured questionnaire and documentary analysis. The analysed data revealed that the causes of the conflict were: competition for scarce resources, bad governance, media incitement, xenophobia, incessant political power struggle and the proliferation of small fire arms entering the country. The effects experienced during the conflict were human rights violation, destruction of property including UN premises and displaced people both internally and externally. Some recommendations made include: Efforts should be made by the Government to strengthen good relationship among different ethnic groups and help them adapt to new challenges that confront democratic developments in the country. The Government should organise the South African style of Truth and Reconciliation Commission to revisit the horrors of the past in order to heal wounds and prevent future occurance of the conflict. Employment opportunities and other income generationg ventures for Ivorian should be created by the Government by attracting local and foreign investors. The numerous rebels should be given special skills training in other for them to be able to live among the communities in Ivory Coast. Government of national unity should be encouraged in situation like this. ECOWAS as well as AU should make sure that when disarmament instituted, it should be done properly. They should always monitor it and not to allow the arms to get into the country again. It is the hope of the researcher that this study makes a contribution towards the prevention of similar conflicts in Africa in the future.

- Description: The purpose of this study was to investigate the causes and the ramifications of the political conflict in Ivory Coast from 2002 to 2009. A purposive sampling was used to select fourteen respondents. Qualitative methodology was used for the study. The data collection instruments were semi-structured interview questions, open-ended Semi-structured questionnaire and documentary analysis. The analysed data revealed that the causes of the conflict were: competition for scarce resources, bad governance, media incitement, xenophobia, incessant political power struggle and the proliferation of small fire arms entering the country. The effects experienced during the conflict were human rights violation, destruction of property including UN premises and displaced people both internally and externally.

- Description: The increase in use and production of engineered nanoparticles in recent years points towards their inevitable release into freshwater ecosystems. Subsequently, exposure to organisms in freshwater ecosystems is to be expected. The aim of this dissertation was to synthesize silver nanoparticles (AgNPs) using silver nitrate, gelatine and maltose as precursor, capping and reducing agent respectively. Cytotoxic effects of the as-synthesized AgNPs was evaluated at concentrations of 0.031 μg/L, 0.250 μg/L and 5.000 μg/L on selected target organs in zebrafish (Danio rerio ) after 96 hr of exposure, under a 24 hr static renewal system. Formation of AgNPs was investigated by UV-Vis spectrophotometry, which displayed absorption maxima peak characteristic of plasmon resonance band for silver at 419 nm. From transmission electron microscopy, AgNPs was found to be small, well dispersed and spherical in shape with a narrow size distribution, and an average particle size of3.76 ± 1.00 nm. Histopathological alterations following exposure to AgNPs was noticed in the gills, epidermis, muscle tissue and kidney. Secondary lamellae hypertrophy, oedema and epithelial lifting was observed in all experimental groups. Curling and clubbed tips of secondary lamellae were observed at the lowest concentration (0.031 μg/L). Hyperplasia and lamellae fusion was most common at the median concentration (0.250 μg/L) of AgNP exposure. Hypertrophy of endothelial cells along with blood vessel congestion was also observed. Reduced secondary lamellar length, lamellar erosion and thinning were observed at the highest concentration (5.000 μg/L).AgNP exposure also altered the shape of alarm cells. In addition, hyperplasia and hypertrophy of goblet cells were observed at the highest concentration (5.000 μg/L) at 96 hr. At 5.000 μg/L of AgNP, PAS reaction was intense (deep purple), while the number and size of these cells decreased. Staining with AB pH 2.5 demonstrated an intense deep purple staining at the lowest and at the median concentration (24 hr). Moderate staining was seen at the higher concentrations. Muscle bundles with severe oedema, their thickening and separation were more pronounced in all treated groups. Histopathological tubular deformation and mononuclear cell infiltration were observed in kidney tissues. In addition; an increase in melano‐macrophage aggregation intensity was identified on the 48 hr in the treated groups. An increase in tubular epithelial cell regeneration/ proliferation, resulting in production of new epithelial cells which was indicative of recovering of kidney tissues from AgNP induced injury at 96 hr of exposure. Results presented here shows that fish respond to the presence of AgNPs.
