A vulnerable group, learners with Fetal Alcohol Spectrum Disorder (FASD) within the Foundation Phase learner population, has often been neglected with regards to literacy development. These learners in many cases do not get optimal teaching and learning due to an inability of teachers to address the literacy needs adequately within the mainstream classroom context. The purpose of this study was to determine the emergent literacy profile of learners with FASD in a Grade One classroom in a selected rural farming community. This study aimed to understand the socio-economic elements that may contribute to barriers in the families of learners with FASD that contribute to the possible emergent literacy problems. As well as highlight the strengths present in the socio-economic context of these families that can be used to support learners with FASD. Bronfenbrenner’s and Morris (1977; 1992) ecological systems theory provided a framework for understanding the complexity of influences, interactions and interrelationships between an individual and various other systems that are linked to the individual. A mixed methods research design was used in order to collect both quantitative and qualitative data. Multi-method data collection strategies were employed in this study. The multi-method approach involved: baseline assessment, interviews and drawings. An interpretive data analysis style was employed for the qualitative data analyses and the quantitative data analysis was statistical. The results of the quantitative and qualitative data were interpreted together. The findings suggest that the participants showed significant challenges in the areas pertaining to phonemic awareness, print awareness, oral language and reading skills. And according to the mothers’ adverse socio-economic environmental conditions also daze the effects of FASD on the learners emergent literacy profile.

M.Ed. (Educational Psychology) / Modern man I s need to contend with a rapidly changing world necessitates the creative and astute use of thinking skills so as to facilitate his adaptation to his environment, and his ability to control his own behaviour. The school has been given the responsibility to teach its scholars how to think. The tendency towards rationalisation has resulted in an increase in the pupil-teacher ratio and this exacerbates the learning problems experienced by the learning disabled child. Though very little recognition has been given to the parents' influence on the development of their childrens' thinking, they arethe logical choice to assist the school in developing their childrens' complex thinking skills, The aim of this study is to establish guidelines for an education programme directed at tutoring parents to assist in the facilitation of the problem solving ski 115 of their learning disabled senior primary school children, A study of the 1iterature regarding thinking, problem solving and parent education, brought to light principles that should be borne in mind when compiling a parent education programme. These principles have been transformed into a set of general and specific guidelines for an education programme for parents of senior primary school learning disabled children. General guidelines are theoretical principles that are relevant to education programmes for the parents of learning disabled children.

M.Ed. (Educational Psychology) / The aim of this study is to establish whether there is significant differences between the aptitudes of succesful freshmen in the B.A. (Law)-, B.Com. (Accountancy)- and B.Sc. (Biological Sciences) fields of study, as well as between succesful freshman male and female students. This study consists mainly out of two parts. Firstly a literature study discussing the concepts aptitude and aptitude testing. Futhermore aptitude and vocational guidance are discussed from an Educational Psychological perspective. Secondly an empirical study was done to establish differences in various aptitudes of the above mentioned fields of study and between male and female students. According to the literature study aptitude can be seen as a combination of factors which enables an individual to achieve a certain level of performance or to develop a certain skill with the necessary training. It is apparent from the literature study that aptitude is inherited; as well as influenced by environmental factors. In early childhood it varies considerably but stabilizes in later years. Slight similarities are present between aptitude and intelligence but a very clear distinction can be drawn. Aptitudes and interests influence each other but according to research, correlations very seldom exist. Differences appear between the aptitude patterns of males and females. The process of vocational guidance consists of three components, namely diagnosis, process and outcome. Vocational guidance is an educational matter which places a responsibility on each educator. Self-knowledge and career-knowledge are a prerequisite for a meaningful choice of a career. In the empirical study a random sample (n = 357) was taken from the successful freshmen at the Rand Afrikaans University for the years 1985, 1986, 1987 from the B.A. (Law)-, B.Com. (Accountancy), and B.Sc. (Biological Sciences) fields of study...

The thesis focuses on the Primary School Nutrition Programme (PSNP), particularly in the Eastern Cape, as a government nutrition and education project, and its failure to achieve its stated goals. The programme experienced problems almost as soon as it was introduced. The press reported incidents of fraud and maladministration and the programme was halted and restarted numerous times. The thesis seeks to offer some insight as to why the government was unable to reach its stated objectives in the implementation phase of the programme. State theory informs the thesis in an attempt to further explain why governments often seem unable to attain their intended goals. The thesis provides an alternative to government development programmes, arguing that NGOs are better equipped to deal with the particular problems that people on the ground experience when dealing with issues like nutritional vulnerability. Operation Hunger provides an excellent case study for how development of this nature ought to occur. The essential argument of the thesis is that there is an inherent tension between what a government's stated intentions is and what, it, in reality, intends to gain from such programmes. It is the contention of this thesis that the Government of National Unity embarked on the PSNP, not to ensure nutritional development for its own sake, but rather to curry favour with its constituents. Operation Hunger, and other organisations like it, provide relief to vulnerable communities with no hidden agenda in mind. Their mandate is solely that they provide assistance. The thesis argues, then, that NGOs have a role in domestic and international politics, that they can make up for or do better, or at least well, things that governments struggle to do.

M.A. (Psychology) / Post-traumatic Stress Disorder has been used to describe an individual's reaction to an event "outside the range of usual human experience". South African society is one fraught with violence, to the point where authors have contended that South Africans have become accustomed to a "culture of violence". Children and Adults are victims of this violence, whether they be directly or indirectly affected by it. In such an unstable society the school can provide children with a setting which offers them stability and a normative influence. In order to make the school effective in the aid it offers its students, teachers have to be assisted in developing and strengthening already existing con-structive ways of detecting and handling of children's problems. Teachers themselves also need to be provided with support in order to assist them with their own personal problems. This study examines the effects of trauma on the teacher-pupil relationship by providing Work, for teachers in order to learn from them and guide them in the assistance they give to children who have been profoundly affected by the violence in their environment being direct or indirect victims thereof. It is my hope that this exploratory study will broaden the understanding of Post-traumatic Stress Disorder and provide useful guidelines in an understanding of the impact violence has on children.

M.E. (Educational Psychology) / The phenomenon of learning disability is evident within many children. This problem obstructs the mastering of basic didactical skills in children. Despite the fact that these children appear to have adequate intellectual abilities, they experience serious .problems in mastering such skills as reading, spelling and writing as well as arithmetical skills. These problems lead to a low selfesteeIll and causes incessant failure in scholastic achievement. Learning disabled children are in need of a highly specialized instructional programme.in order to overcome their learning problems. In Transvaal, provision is made for learning disabled children by aid class placement. Many parents however have objections against placement in aid classes in that their children become "exeptional children". They believe that their children can overcome their learning problems by means of their remedial programmes. It was thus essential to arrive at a psychological and a didactical view of the learning disabled child. Furthermore it was necessary to undertake a psycho-didactic consideration of reading- and arithmetic problems. Aid class instruction and alternative remedial procedures as such, were emphasized. The purpose of this study therefore was to determine whether learning disabled children could adequately overcome their learning problems by means of alternative remedial procedures. Two groups of learning disabled children were identified id est those who were placed in aid classes and those who were for various reasons not placed in aid classes. Three different reading tests as well as addition and subtraction tests were administered to ascertain the children I s level of scholastic achievement.

M.A. (Psychology) / One of the most perturbing facets of South Africa's post apartheid communal existence is the high incidence of Post Traumatic Stress Disorder (PTSD) amongst the disadvantaged communities. It is noteworthy that the incidence of PTSD amongst urbanised black youth is so high, that it can be described as an epidemic. Since therapeutic resources are limited or absent in many environments , it is essential to develop a project to cater for the needs of traumatised communities. Such programs should be cost effective and must relate to education within a psychological context. Following a diligent study of the literature, it was decided that a theoretical behavioural project be developed which utilises a psycho educational context that can be applied to black youth with PTSD.

M. Ed. / In South Africa many people have been directly or indirectly involved in criminal and/or violent acts either as victims or as perpetrators. Research has shown that violence in its various forms, be it political, criminal or domestic, is endemic in South Africa (Stravou, 1993; Turton, Straker & Moosa, 1992). According to Gibson, Mogale and Friedler (1991:1), political violence, especially in South African townships, has been enacted between the ANC and Inkatha and this violence is regarded as an extension of the years of a violent state of repression. As violence escalates it has become impossible to make a distinction between political and criminal violence. Rauch (1993:11), who points out that "it should also be borne in mind that ordinary criminal violence is not always distinguishable from political violence", supports this statement. Stravou (1993:3) echoes this in his observation that ordinary criminal violence can be caused by political factors, alcohol abuse, poverty, unemployment and dangerous living conditions. As both criminal and political violence increase in the townships, domestic and criminal acts against women and children in South Africa are rated the highest in the world (TV News, 13 May 1999). This is an indication that violence has not only destroyed individual lives, but also affected communities, children and family institutions. This notion is emphasized by Klaaste (no date, cited by Phetla 1998:31), when he stated that "The violence in this country, particularly in the townships, has destroyed more than just property and structures, it has destroyed the emotional institutions, the very substance of family life and society. In the past, there was always a very strong understanding of hierarchy, of who was who in the family". However, today the anchors have been destroyed, and there is nothing to hold many families together. This is a cause for concern, because families are the fabric of communities and societies. As families are affected, children who are the future generation of society, are also continually exposed to this violence. Children become victims because of their vulnerability and exposure to insecure and unstable environments in which they live. Many schools, which these children attend, were historically regarded as stabilizing influences on the social environment, providing necessary support and guidance for them have now turned into war zones. Young learners have to contend with guns and knives on a daily basis, an indication of how endemic the violence is in the learning environment. The Star (Thursday, May 12 1999) reported that a school principal was shot dead and her car taken in front of her learners. TV news (13 June 1999) reported that "another teacher has been brutally murdered in front of her grade one class by unknown gunmen". This situation occurs within the environment where children live, and appears to have serious repercussions later in their lives. Exposure to and involvement in escalating violence, both in their homes and neighbourhood, can lead to post traumatic stress syndrome in children (Kerr & Nelson, 1998:268). This includes nightmares, irritability and other forms of behavior problems like aggression. Stravou (1993:3) is of the opinion that witnessing a violent act, affect children in general more severely than adults. It can also be argued that violence and political instability will affect children's development adversely. In South Africa where 70% of the population is under the age of 18 years, the implications are devastating (Byne, 1993:3), especially in the townships. Katlehong, a township in the Eastern part of Gauteng, experienced tremendous violence during the years 1985-1995, because of the faction fights between two political parties, the African National Congress and the Inkatha Freedom party. Many people were killed, tortured, abducted and subjected to various forms of severe ill treatment. Reports like these are all too common in South African Black Townships, mixed in with miscellaneous reports of general community and domestic violence. Although among the people of Katlehong violence seems to be largely a thing of the past, its trauma remains and the children still bear the marks. Young people have become socialized to violence as a way of solving conflict. This attitude was indicated in a personal interview, which I conducted with teachers at the Kabelo Primary School prior to my study. In the interview one teacher had indicated that, "Most of our children are experiencing behaviour problems like aggression, and others experience difficulties in paying attention and concentrating in the classroom". This type of behaviour is regarded as the after effect of violence. As a result of the increase in violence, it has become clear that there is a vast need for psychological counseling for South African children who live in places like Katlehong, which have been constantly involved in acts of violence. Dawes (1994:6) supported the need for this service when he pointed out that "the need for psychological healing is overwhelming but, most unfortunately, for these children there are not enough psychological services to help alleviate these problems". It is not only the non-availability of these services that prevents children from accessing psychological interventions, but also a lack of knowledge about psychological difficulties and counseling among parents. Owing to this lack of knowledge, also with regard to possible interventions, society in the past tended to take a punitive rather than a rehabilitative, attitude towards an antisocial, aggressive youth (Carson & Butcher, 1992:545). In the townships, a punitive attitude was often to apply physical punishment in the form of corporal punishment; this, however, is seen as humiliating and antagonizing for children (Davis, 1996:291). In addition, corporal punishment has also shown to intensify rather than to correct aggressive behaviour, as reported by Omani (1982 cited by Mwamwenda, 1992:318) who argues that beating young children should be seen as an act of aggression that does not teach children conflict resolution. A study that supports this statement was carried out by Potegal and Knutson (1994:183), who reported in their finding that children who were struck after a simple tantrum had significantly higher frequencies of tantruming. Therefore, corporal punishment is regarded as an authoritarian and conservative way of disciplining children, that does not improve their abilities to deal with conflict nor deepen their understanding to their own emotional and social functioning. These results indicate that some variables that had been used in the past to deal with aggressive children can cause children to manifest antisocial behaviour like aggression (Farrington, 1992:260). From the researcher's experience, township parents often discipline their children by scolding them and they do not often encourage them, especially boys, to express their feelings freely. Scolding is regarded by Davis (1996:289) as verbal aggression, and is defined by Vissing, Straus, Eilees and Harrop (1991:224) as a communication intended to cause psychological pain. Its effects are low self-esteem, anger, anxiety, depression, academic underachievement and lying (Davis, 1996:289). Suppression of feelings among African children is indicated by Mandela's statement in his book "Long Walk to Freedom". When he recalled various aspects of his circumcision, he said that "flinching or crying out was a sign of weakness and stigmatized one's manhood; man must suffer in silence" (Mandela, 1995:12). According to Oaklander (1992:207) if a child is unable to express his feelings, he bottles them up, and becomes angry. In order for him to express his anger and his thwarted self, Oaklander (1990:208) adds that the child pushes on to "become something beyond his awareness, he can retroflect the anger by having headaches and stomach aches, or deflect the true feelings by hitting, kicking and striking out". Such a child is mostly regarded as aggressive, and according to Bierman (1989:36) children like this, who acquired non-compliant and violent behaviour patterns at home are at high risk for reacting aggressively towards their teachers and peers as an outward expression of emotional turmoil. Stravou (1993:11) is of the opinion that children learn to believe that aggressive attitudes and violent behaviour are normal and acceptable, in an environment where violence is viewed as an acceptable way to get and to maintain power and solve problems.

Sildenafil citrate (SC) is a phosphodiesterase-5 inhibitor that is used to treat pulmonary hypertension (PH) in paediatric patients. The purpose of these studies was to develop a formulation and manufacture an orodispersible tablet (ODT) that can be easily administered to neonates and children with PH. The advantages of ODT dosage forms include ease of administration, rapid dissolution of the API, SC. Furthermore the dosage form can be taken without water which is beneficial to patients without immediate access to potable fluids. A simple, rapid, accurate, precise and selective reversed-phase HPLC method was developed and validated in accordance with International Conference on Harmonization (ICH) guidelines and was successfully used for the analysis of SC as raw material and in SC containing pharmaceutical dosage forms. Preformulation studies were performed on SC, alone and in combination with potential excipients that could be used to make tablets. Investigations into potential interactions between SC and the excipients were performed using Differential Scanning Calorimetry (DSC) and Infrared Spectroscopy (IR). DSC results revealed that SC was compatible with all potential excipients except mannitol and magnesium stearate. However these interactions were not observed with IR and therefore it was concluded that the interactions were induced by the high temperatures that DSC operates at. Particle size and shape was also established by use of Scanning Electron Microscopy (SEM) and flow properties were monitored by calculating Carr’s Index (CI) and the Hausner Ratio (HR). Direct compression was used as the method of manufacture for SC tablets as this approach is simple and the most economic production approach. The powder blends were assessed for bulk and tapped density and the CI and HR were used to determine the flowability of the blends. The quality attributes of the resultant tablets that were monitored included uniformity of weight, friability, crushing strength, tensile strength, disintegration, wetting and in vitro dispersion times. Design of Experiments is an efficient statistical approach that has become a popular tool used in the pharmaceutical industry to optimize formulation compositions, as it allows for the investigation of several input factors at the same time whilst not using the tedious and traditional “ modification of one variable at a time” approach. A Central composite experimental design was chosen as the most appropriate means to optimize the formulation as it produces more accurate results as opposed to other experimental designs approaches as input factors are investigated at five different levels. Through the use of mathematical modelling, optimum concentrations of disintegrant(s) and an appropriate blending time were established. Analysis of the data from the experimental design and mathematical modelling studies reveal that no changes in disintegrant concentration or blending time altered the disintegration time of the formulation to any significant extent. This result is most likely due to the fact that the critical disintegrant concentration has been reached and increasing the disintegrant concentration further has no effect on disintegration time. It was also established that a change in the concentration of CMS and CRP altered the wetting time of the tablet significantly. Finally it was noted that there was a linear relationship between blending time and the uniformity of content of the tablets produced in these studies. The optimized product was a white tablet with a diameter of 7.31 mm with a thickness of 2.80mm.The dosage form had no visible cracks or evidence of picking or sticking. The tablet exhibits suitable friability and tensile strength while exhibiting a disintegration time of only 8s. Therefore an orodispersible tablet containing SC intended for paediatric use has been successfully developed, manufactured and optimized through the use of preformulation studies, appropriate quality control monitoring and mathematical modelling. These formulations require further optimization in respect of addition of flavours and or additional sweetening agents.
