  • Description: Pupils in the Republic of South Africa in the T.B.V.C. States (Transkei, Bophuthatswana, Venda and Ciskei) are expected to commence study in all school subjects, except the first language (Xhosa, Tswana, Venda etc.) and the third language (Afrikaans), through the medium of English at the Std 3 level. English thus is the official medium of instruction for the greater part of the pupil's school experience. All examinations in all subjects (except those mentioned above) are set and answered through the medium of English. School textbooks from Std 3 upwards, in all subjects, are written in English. It is fairly safe to assert, therefore, that English should be the language life of the Higher Primary and Secondary School classroom. In 1953 a UNESCO report of proceedings of a conference held in 1951 maintained that the best medium for teaching a pupil was that of the mother-tongue. The report pleaded for mother-tongue instruction to be extended to as late a stage as possible in a pupil's school life (UNESCO 1953). While such a plea may be grounded on sound psychological and pedagogical reasoning, it is often ignored because of the realities existing within the educational system. The R.S.A. and the T.B.V.C. states are a case in point for as I have already mentioned, examinations, textbooks, and for that matter tertiary education at the post-matriculation level, all employ English as instructional medium. Pragmatism carries the day and the black pupil is compelled to use English. Other factors applicable to the South African context are the existence of many different ethnic groups, each with its own language, and the fact that a shortage of qualified and experienced teachers in many subjects and different levels within the schools has meant that often teachers whose first language is English are involved in teaching pupils from these various language groups

An empirical phenomenological study of happiness

- Parker, Peter Burns

  • Authors: Parker, Peter Burns
  • Date: 1987
  • Subjects: Happiness
  • Language: English

  • Description: The aim of this study was to investigate man's attunement when happy. Having established a question which would elicit actual experiences of this phenomenon, the researcher collected sixty-four written accounts of the experience. Of these he chose the twelve psychologically richest accounts and, having interviewed each of these twelve subjects to push their written descriptions to their limits, he analysed the resulting protocols using an empirical phenomenological method. The general structure of the experience of happiness suggested that happiness emerged as a special openness against a background where individuals were less than happy. During happiness there is a breaking through the bonds of the individual's mundane, everyday disclosure of the world. It transports the individual to an existence in which the ruptures which form part of man's lived relationships to himself, to his fellowman, to the world and to life itself are healed, and in which life is lived in increased harmony with all. There is a coming home to the self, a move toward wholeness which is enlivened bodily by a radiating vibrancy (often a tingling lightness and brightness), as the individual expands with energy, power, self-confidence and mastery, and rises above the troubles of life. This structure of happiness was dialogued with the writing of existential philosophers and psychologists, psychoanalysts and humanists

An intelligent computer-based tutor for elementary mechanics problems

  • Description: ALBERT, an intelligent problem-solving monitor and coach, has been developed to assist students solving problems in one-dimensional kinematics. Students may type in kinematics problems directly from their textbooks. ALBERT understands the problems, knows how to solve them, and can teach students how to solve them. The program is implemented in the TUTOR language and runs on the Control Data mainframe PLATO system. A natural language interface was designed to understand kinematics problems stated in textbook English. The interface is based on a pattern recognition system which is intended to parallel a cognitive model of language processing. The natural language system has understood over 60 problems taken directly from elementary Physics textbooks. Two problem-solving routines are included in ALBERT. One is goal-directed and solves the problems using the standard kinematic equations. The other uses the definition of acceleration and the relationship between displacement and average velocity to solve the problems. It employs a forward-directed problem-solving strategy. The natural language interface and both the problem-solvers are fast and completely adequate for the task. The tutorial dialogue system uses a modified version of the natural language interface which operates in a two-tier fashion. First an attempt is made to understand the input with the pattern recognition system, and if that fails, a keyword matching system is invoked. The result has been a fairly robust language interface. The tutorial is driven by a tutorial management system (embodying a tutorial model) and a context model. The context model consists of a student model, a tutorial status model and a dynamic dialogue model. ALBERT permits a mixed initiative dialogue in the discussion of a problem. The system has been tested by Physics students in more than 80 problemsolving sessions and the results have been good. The response of the students has been very favourable

  • Description: From Introduction: While companies in their initial stages may well produce only one product, most established companies produce a number of products. Reference can therefore be made to their product mixes which serve as their source of revenues and profits. The product mix must be carefully planned. Inherent in such planning is the monitoring of the mix to determine whether or not it strikes a good balance in terms of factors such as sales growth, sales stability and profitability. The product mix must be optimal vis-a-vis the opportunities and threats present in the external environment at any point in time. Since the latter changes over time, so too should the product mix change in order to maintain the required balance between the environment and the product mix, as well as the required balance in terms of sales growth, sales stability and profitability.

Anorogenic alkaline ring-type complexes of the Damaraland Province, Namibia, and their economic potential

- Potgieter, J E

  • Authors: Potgieter, J E
  • Date: 1987

  • Description: Anorogenic alkaline ring-type complexes form within continental plate settings. Alkaline magmatism is derived from the upper mantle, in which mantle metasomatism plays an important part, as well as from partial melting of the lower crust. Radial and concentric fractures develop during the ascent of alkaline magma. Extrusion of basic and felsic magma takes place along these fractures with felsic volcanics building-up central volcanoes. As a result of emptying of the magma chamber, the superstructure of the volcano collapses and a caldera is formed. During the caldera stage syenitic and granitic material are intruded into ring fractures. Alkaline ring-type complexes may be classified as (i) alkaline qranite and syenite-type and (ii) carbonatite and undersaturated-type. These ring-type complexes occur as distinct igneous provinces. Some major provinces occur in Brazil, Corsica, Namibia, Nigeria, Norway, Saudi-Arabia and Sudan. In Namibia the Damaraland igneous province is of Mesozoic aqe and it contains 15 alkaline ring-type complexes . These complexes are situated along north-eastern trends which correspond to transform directions of the South Atlantic. During the opening of the South Atlantic (Gondwana breakup) Pan-African age lineaments were reactivated which allowed emplacement of anorogenic alkaline magmatism. A zonation of alkaline granite and syenitetype in the west and carbonatite and undersaturated-type ring-complexes in the east correlates with down- and upwarp axes parallel to the line of Gondwana fragmentation. Alkali- and H⁺-metasomatism is related to the alkaline and syenite-type whereas alkali metasomatism (fenitization) is associated with carbonatite and undersaturated-type ring-complexes. Sn, W and Ta mineralization is associated with alkaline granites of some of the alkaline granite and syenite-type ring-complexes. Fe, F, PO₄ , Nb, Th, REE, Sr, Zn and Pb mineralization is associated with carbonatite complexes. Potential exists for: (i) porphyry Cu-Mo and epithermal-type (Au, Ag, Pt-metals, base metals) mineralization in the alkaline granite and syenite-type ring-complexes and (ii) disseminated Cu, Au, Aq and Pt-metals in carbonatite and undersaturated-type ring-complexes
