- Description: Background. As a result of the AIDS pandemic, many people areimmuno compromised andopportunistic fungal infections (OFIs) such as candidiasis are common. Despite the widespread use of medicinal plants in South Africa, there is a dearth of knowledge regarding the use of such plants in the management of these infections. This study evaluates three South African medicinal plants (Arctotis arctotoides, Pittosporum viridiflorum, and Gasteria bicolor) traditionally used in the treatment of OFIs in HIV/AIDS patients, in the Eastern Cape Province, South Africa. Materials and methods. A six-stage process of documentation, evaluation and analysis of results was conducted: (1) Selection of medicinal plants most frequently used in the treatment of OFIs through ethnomedical studies and the survey of specialised literature; (2) Collection and preparation of the extract of each plant; (3) Antifungal evaluation of the crude plant extracts. (4) Phytochemical and antioxidant evaluation of the active crude plant extracts; (5) Cytotoxicity evaluation of the bioactive extracts using the Chang liver cell line, and (6) Statistical analysis of the results. Ethnobotanical information was obtained through interviews with traditional healers and AIDS patients with the aid of semi-structured questionnaires, direct observations and by reviewing studies reported in the literature. Following the approval from the University of Fort Hare‘s Ethics Committee, 101 HIV/AIDS patients were recruited through convenience sampling into an anonymous cross-sectional questionnaire study. The agar diffusion and micro-dilution methods were used to determine the antifungal activities of the hexane, acetone and aqueous extracts of A. arctotoides, G. bicolor and P. viridiflorum against 10 opportunistic fungi.

- Description: In this study the main focus is on the experiences of former street children as learners. The main emphasis of this study is the manner in which such experiences influence these children’s learning towards constructing new identities. By examining the experiences of former street children in a school environment, namely a teaching and learning environment, this study will contribute towards the literature by providing focused and relevant information pertaining to the way former street children experience learning. By focusing on these particular learners from the street, the study attempts to explore and build an insightful knowledge in terms of understanding how former street children perceive learning in relation to their present personal and past life on the streets. Through this study the researcher will hopefully be able to determine how former street children feel, experience and relate to teaching and learning within a school context. Data collection for this study included the researcher’s observations and face-to-face unstructured in-depth phenomenological interviews with learners who are formerly from the streets. Among others, the study found that these particular learners have low self- esteem, a low opinion of themselves, and lack of self- confidence. The study also revealed that some of these learners are struggling academically and would appreciate it if academic was parallel with vocational skills so as to equip them for the world of work. It also transpired that learners who have relationships with those who have not been to the streets changed their lives for the better by learning from their peers but those who have relationships with other former street children at this school continue to engage in deviant behaviour, for many schooling has helped them to reclaim their childhood identity.

- Description: This study investigated challenges encountered by schools in the implementation of inclusive education in the Eastern Cape. It was a Survey Study carried out in Ngcobo District. School principals of randomly-sampled mainstream schools and special schools participated in this research project. The key research question that the study sought to answer was: What are the challenges encountered by schools in the implementation of Inclusive Education in the Ngcobo District of the Eastern Cape Province? The following were the sub-research questions: (a). How does the lack of specialized or in-service, trained human resource personnel challenge or hinder the implementation of Inclusive Education? (b). How is the implementation of Inclusive Education affected by available infra-structure? (c). How do the attitudes of stake holders such as learners, educators (ILST) and parents (SGB) affect the implementation of inclusive education? The findings of the study revealed that: There is a gross shortage of educators qualified in inclusive education or related streams, and in some schools none at all. Institution Level Support Teams (ILSTs) in some schools have not been established and some of those that are established are not functional. Needed specialists such as psychologists and occupational therapists are not available in special schools. Workshops or in-service training for educators generally are held for to ILSTs only instead of all educators and SMTs. School buildings and toilets have not been adapted for when inclusion is to be implemented and there are no specific, funded departmental projects to rectify this. Assistive devices for learners experiencing barriers to teaching, learning and development are rarely found. There are no clear departmental budgets to ensure the policy is implemented in ordinary schools. Negative attitudes of some parents, teachers and learners toward inclusion still exist. The following recommendations were made for consideration in order to facilitate the smooth implementation of Inclusive Education in the schools. There should be adequate provision of human resource training and development Educators have to further their studies in Inclusive Education. There should be provision of a specific budget for buildings. Maintenance funds ought to be used to renovate school buildings so as to be Inclusive Education friendly. Advocacy and awareness programmes for different stakeholders should be conducted.

- Description: This research sought to understand the perceptions of the township dwellers who are the beneficiaries of the RDP houses in a selected township, Chris Hani block 3 in Mdantsane, East London, in the Eastern Cape. The study specifically sought to establish whether the houses delivered to the residents through the Reconstruction and Development Programme (RDP) adequately meet the basic standards prescribed by the relevant housing policy of South Africa. During the apartheid era black South Africans were marginalised, their development was separate from that of whites and they had no say in what was provided for them, hence they were inadequately housed. On coming into power, the post-apartheid government undertook through legislation to provide sustainable, adequate housing that would address the needs of the historically disadvantaged citizens/poor people of South Africa. The main finding of this study conducted on a sample of ten RDP housing beneficiaries, through personal interviews is that, the RDP is a good programme; however, its implementation is characterised by corruption and greed. The people, whom the programme is meant to benefit, have never been involved in their own development with the results that the houses provided to them, are of a sub-standard quality. The houses do not adequately address the housing needs of the people. The housing policies are also not adequately implemented. It is the author’s hope that the recommendations made by this study, if implemented, will improve the standard of the RDP houses provided to the poor people of South Africa.

- Description: Teenage pregnancy is one of the major factors leading to girls dropping out of school especially in developing countries such as South Africa. To address the problem, the South African government has put forward policies which allow for the continued enrolment of learners who could fall pregnant while at school. However, there is evidence that pregnant learners drop out of school even though these policies are in place. Hence this study investigated the perceptions of the school stakeholders on the mainstreaming of pregnant learners and one of the stakeholders is the pregnant learners themselves. This study also aimed to investigate the way pregnant learners were perceived and treated in their schools and the views of the stakeholders on supporting the pregnant learners academically. It also aimed to explore leadership and management implications of the school stakeholders’ perceptions. This study revealed that some of the stakeholders were not aware of the existence of the policy that allows for the mainstreaming of pregnant learners in public schools. Those that indicated that they were aware of it reported to have a fuzzy idea of the policy. It seemed there was no shared understanding of the policy among the stakeholders; as a result the policy was not effectively implemented in the schools. This could also be the reason for the negative attitude shown by some of the school stakeholders to the policy. However, all stakeholders voiced out their opinions about this policy. With regards to the policy implementation they expressed fears that the educators may not be capacitated enough to deal with learner pregnancy and also that the pregnant learners may have a negative influence on other learners. Cultural beliefs and stereotypes seemed to play a role on how the stakeholders perceived the policy that legislated the mainstreaming of pregnant learners.
