An investigation was conducted into possible differences in motor abilities between 98 mentally retarded and 100 mentally normal girls aged between 13 - 17 years. For the purpose of this study certain motor aspects as contained in previously selected tests were chosen. The motor aspects in question were those which appear in the Physical Education Syllabus for girls in the section handling of objects. The success with which the girls performed the prescribed movement tasks was measured quantitatively (to indicate attainment of the desired result) as well as qualitatively (to indicate the movement pattern) . A movement-directed analysis was conducted by studying the possible effect which the kind of skill, as well as the relative perceptual-motor abilities, could have on the achievement of the pupils. A preceding literature study was done in order to obtain relevant information pertaining to the study. The quantitative data were studied by means of a variance analysis investigation with a view to the significance of the differences (p ~ 0,05), while the qualitative data, being nominal, were analysed by means of chi-square techniques. The predominant findings indicate that, in spite of heterogeneity within the group, deficient motor ability is indeed prevalent among the mentally retarded pupils. This does not, however, hold good for all aspects of the movement abilities and is not always meaningful. The biggest differences are found in the movement pattern. Task complexity, the degree of cognitive involvement as well as perceptual-motor abilities included in the skills do play a role as regards the successful performance by the mentally retarded group. Carefully planned motor programmes conducted with retarded pupils could therefore be a means of abolishing under-actualization of their personality realisation - especially as they are directed towards motor rather than cognitive orientated occupations. / Thesis (MA)--PU vir CHO, 1987

Conselho Nacional de Desenvolvimento Científico e Tecnológico / Ce travail vise à expliquer comme les motifs de la différance et de l'écriture évoquent les préoccupations éthiques et politiques qui nous permettent d'affirmer que ce qui est communément appelé dans la seconde moitié du XXe siècle, la déconstruction est, à partir de sa formulation initiale, éthique et politique. En ce sens, nous percevons comment l'extension de la notion de l'écriture, comme en témoigne le philosophe français-algérien Jacques Derrida, nous permet de déplacer les catégories dont traditionnellement ont organisé les domaines éthiques, juridiques et politiques, que maintenant sans des alibis métaphysiques qui leur sont si uniques, nous permettent de penser des nouvelles façons de faire justice à la singularité de l'autre. / Este trabalho tem como objetivo explicitar como os motivos da différance e da escritura evocam preocupações éticas e políticas que nos permitem afirmar que aquilo que se convencionou chamar, na segunda metade do século XX, desconstrução é, desde sua formulação inicial, ético-política.

(in English): This paper focuses mainly on the problem of the Mesolithic-Neolithic contact in the Iron Gates gorge at the turn of the 7th and 6th millenniums BC. A special emphasis is put on the eponymous site of Lepenski Vir. From a geographic point of view, this area represents a natural border between countries Serbia and Romania. There, in different layers and at different locations, were excavated and explored settlements documenting activities and social contact between the Mesolithic and Neolithic populations, as well as the transition from the Mesolithic way of life to the sedentary Neolithic one. The first part of the paper is devoted to an overview of scientific research, a development of views on the process of Neolitization and all the important aspects of culture. The second part deals with the examination of the first form of contact between Mesolithic and Neolithic populations based on the results of natural and archaeological research with theoretical application of the migration model, from the American anthropologist David W. Anthony.

Computer games have not only invaded the lives of children, but the lives of adults as well. Increasingly, computer games have become a part of popular culture. Initially computer games were considered to be a waste of time, time that could have been better spent doing more worthwhile activities such as studying and physical exercise. Recently, however, attitudes towards computer games have changed; teachers, parents and researchers have started to regard computer games as a possible educational resource. During this new information age it is possible that the children who are part of the Net generation have started to think and process information differently, and that they may have different educational needs. Some researchers think that computer games may serve as an educational tool to support their learning. This literature survey provides an overview of current literature on computer games and education. The review examines the aspects of computer games that support learning, such as motivational factors, social interaction and learning through doing. Further, the review studies the negative aspects that prevent games from being accepted as an educational tool such as the violence portrayed, game addiction, negative stereotyping and asocial behaviour. The Net generation is also examined. The review looks at their characteristics, thinking patterns, skills and their expectations of education. The review then serves as a basis to provide some guidelines for the selection and usage of computer games in the classroom. / Dissertation (MEd (Computer-Integrated Education))--University of Pretoria, 2007. / Science, Mathematics and Technology Education / unrestricted

I present a study done to determine the characteristics of the LHIRES III spectrograph on the 20 inch RC Optics telescope at Hard Labor Creek Observatory. I describe the settings of three different diffraction gratings, collimation and focus issues, and practical aspects of use. The spectrograph was used with a SBIG ST-8XME camera for all studies. Data collection was accomplished with the Maxim DL software package and analysis was completed with IRAF. Solutions for the dispersion relation with all three diffraction gratings were found. Several projects are underway with this instrument. I present time series spectra of α Vir to demonstrate the practical applications of the spectrograph. This non-radially pulsating star shows Doppler shifts that were recorded in the Si III 4552, 4568, 4574 Å triplet over the course of a night. The observed profile variations showed the spectrograph capable of exacting scientific work.

The aim of this research is to determine the therapeutic possibilities in music and books, in group work with middle aged deprived children. Deprivationwith children is an encompassing problem which social workers daily grapple with. A lack of sufficientknowledgeabout deprivationand sufficientknowledgeon the way inwhich to solve the problemmakesit essentialto do researchon the subject. Literature analysis and an empirical research are the two methods used in this study. The literature analysis focuses on the characteristics of the child client, the value of play for the child and the different ways of playing. This is followed by an explanation of the development of the normally developed middle aged child compared to that of the deprived middle aged child. The therapeutic possibilitiesof music and books is also discussed. Experimental research was used for this empirical research. An experimental group and a controlled group was compiled out of deprived middle aged children. Measurements were taken before and afterwards according to an adapted Hudson scale. Music, books and other therapeutic resources were used in the group work with the experimental group. The hypothesis states that the therapeutic use of music and books in work with groups amongst deprived middle aged children results in improvements of behaviour and relationships. The empiricalresearch proved that the therapeutic use of music and books lead to the improvement of behaviour, such as co-operation and consentration and to the establishmentof a therapeutic relationship between the group members and group leader. / Thesis (MA(MW))--PU vir CHO, 1994

The objective of this study is to investigate the picture book as a form of communication. The investigation comprises both a theoretical and a practical approach. An extensive literature survey was undertaken, publishers interviewed and visits undertaken to process and printing houses to establish the methods and approaches that are currently employed to produce a picture book. The theoretical formulation forms the background and motivation to the practical aspect of the study. The practical component entails the actual conceptualization, design, illustration and publication of a picture book. The possibilities and constraints imposed on the illustrator, comprising all the elements that influence and shape the communication process, are presented and discussed - firstly in theory and then in direct reference to the picture book which is bei:1g illustrated. The theoretical and practical components of this study combine to show up the picture book as a unique art and literary form. The manner in which successful communication is achieved through the effective utilization of all the processes and elements that combine to form the picture book is demonstrated. This study emphasizes that the illustrator should get to know and use all possibilities and restrictions to their full advantage to create an effective, unique interpretation and expression in picture book form. / Thesis (MA (Beeldende Kunste))--PU for CHE
