  • Description: This study involves an investigatioh into the nature and effectiveness of the pre-service training, where provided, of secondary school Mathematics teachers at the 11 colleges of education administered by the House of Representatives in the Republic of South Africa. The purpose of this study is to determine whether the HDE (Secondary) course offered at some of the aforementioned colleges of education is justified, In spite of the fact that it contravenes the requirements of the Education Act, No. 73 of 1969. Three different questionnaires were designed and during 1986 were sent to heads of Mathematics departments at the aforementioned colleges of education , to Mathematics teacher educators at these colleges and to beginning secondary school Mathematics teachers, teaching at schools administered by the House of Representatives in the Eastern Cape and Natal. The findings of this study show that the secondary course for Mathematics teachers is only offered at 5 of the 11 colleges of education and only a small percentage of students take this course. During 1986 most of the Mathematics teacher educators at the colleges of education were not suitably qualified. The study also shows that the Mathematics curriculum for the training of secondary school teachers is inadequate and a revision thereof is thus recommended. An obvious conclusion drawn from the findings is that the training of secondary school Mathematics teachers at these colleges of education is still in an early stage of development. One of the main recommendations of this study is that the training of secondary school Mathematics teachers at colleges of education administered by the House of Representatives should be terminated , in view of its ineffectiveness and In accordance with Education Act , No . 73 of 1969. On the other hand, in case this is not possible, suggestions are also made for the improvement of the pre-service training of secondary school mathematics teachers at these colleges of education.

  • Description: The purpose of this investigation was to determine the properties that characterise cotton fibres in the various stages in the CPNF process as well as to determine which fibre characteristics a r e required to entangle the fibres to produce a successful CPNF . The criteria adopted in this work for a successful CPNF include: 1. the tensile strength of the fabrics 2. a well-defined pattern 3. absorbency and wicking The properties selected for investigation were 1. the cotton fibre surface (using SEM and DSC analyses) 2. the degree of degradation of the cotton fibre as a result of the CPNF process (using cellulose fluidity measurements) 3. the non-cellulosic content of the fibre (using IR, DSC, and Chemical analyses) 4. fibre friction 5. absorbency and wicking 6. tensile properties Analysis of the results indicates clearly what the fundamental properties of the cotton fibre must be for a successful cotton CPNF to be manufactured. The conclusions also indicate the necessary properties a man-made fibre must have to produce a successful CPNF.

  • Description: School guidance aims to meet the social/personality, educational and vocational needs of pupils, and the curriculum, organised and drawn up by the relevant State education departments, attempts to address these needs. This investigation set out to discover the guidance needs of pupils specifically in the social/personality area, and further, to state these needs in such a way as to allow the logical development of guidance programmes. Group and individual interviews were conducted using a sample of 72 high school pupils, selected from standards six to eight. The results show clearly the areas in which the pupils perceive their needs to lie. It is also apparent that further research in this area is strongly indicated.

  • Description: The focus of this research was the reappraisal in physiological and psychophysical terms of current equivocal theories regarding the onset, course and termination of apneic bradycardia. Sixteen healthy male subjects participated in four separate testing sessions . Maximal oxygen consumption (VO₂ max) was measured on land and underwater using an identical direct, continuous progressive cycle ergometer test. On each of two other occasions subjects exercised in either environment at 50, 70 and 90% of the appropriate VO₂ max, during which time heart rate was continuously recorded. An initial apneic bout at each exercise intensity was followed by performance of the same workload without apnea for an equivalent period of time. Ratings of perceived exertion (RPE) were also monitored. While apneic bradycardia occurred at each exercise intensity studied underwater, it was apparent only at 50% VO₂ max on land. With the exception of between 50 and 90% VO₂ max on land, the mean apneic heart rates did not differ with varying exercise intensity (p<0.05); nor did the lowest heart rate recorded, although this was lower underwater than on land. Apart from 70% VO₂ max on land, apneic heart rates were lower than the equivalent values measured during exercise without apnea. Land and underwater heart rates during apneic and non-apneic conditions did not differ until 90% VO₂ max. The effects of increasing exercise intensity upon the onset of bradycardia were evident in that it occurred earlier at 50% VO₂ max underwater than at the heavier workloads, and only at 50% VO₂ max on land. The mean breath-hold duration did not differ between the land and underwater environments, nor was it affected by increasing exercise intensity. The order in which breath-holds was performed did not alter the length of apnea. Land and underwater RPE did not differ and increased with increasing exercise intensity in both environments. During apneic exercise RPE was greater than the equivalent exercise without apnea. Twelve of the original 16 subjects were divided equally into two groups on the basis of vital capacity expressed relative to body surface area. Vital capacity was measured during the first laboratory session. Neither the mean heart rate response to apneic exercise at 50% V0₂ max in both environments, nor the lowest heart rates recorded differed between groups, prompting the conclusion that lung volume did not affect apneic bradycardia. Despite a longer breath-hold duration for Group A (large relative lung volume) than Group B (small relative lung volume), the onset point of bradycardia was the same for either group when expressed relative to total breath-hold duration

  • Description: If I am aware of my own mental states by introspection (a) How can I know that other people have minds? and (b) How can I know what their mental states are? These are two of the questions with which I will be concerned in this dissertation. I discuss five different attempts to deal with them. (i) The claim that we can know that other people have minds by an argument from analogy. I show a number of serious flaws in Russell's and other versions of this argument. (ii) Malcolm's thesis that the criteria by which we apply mental terms to others are just different from the criteria one applies in one's own case. I argue that Halcolm's accounts of both first- and third-person criteria are not adequate. (iii) I consider Strawson claim that 'persons' is a primitive concept and that behavioural criteria are "logically adequate" for determining the correctness of statements about the mental states of others. I argue that both of his key concepts are underanalysed. (iv) A quite different attempt to answer our questions (a) and (b) is given by the empirical realist who argues that knowledge claims about other minds are best understood as hypotheses in a wider psycho-physical theory. I show that the major fault in Putnam's version of empirical realism is that he overlooks the subjective character of (iii) our mental states. (v) Finally I consider the claim, due to Nagel, that a conception of mental states is possible which incorporates both subjective and objective aspects of the phenonemon. I speculate that with a great deal of development this approach might hold the answer to our questions.

Aspekte van die prosa van Boerneef met spesifieke verwysing na die bundel Boplaas

  • Description: This thesis is a report on a "rereading" (in the sense in which Roland Barthes uses the word) of the short texts of Boerneef (Izak Wilhelmus van der Merwe 1897-1967) published under the title Boplaas in 1938. Boerneef's prose is explored with specific reference to this one volume. The unity of the volume of texts is examined and textual indications of relations with other texts in the oeuvre are explored. In this way the thesis indicates how transtextuality determines meaning both in the individual texts as well as in the volume as a whole. The process of (re)reading in this thesis traces how, as a result of the exploration of the textual elements, a Boplaas code is generated. This Boplaas code signifies both the space and the ethos of Boplaas. Paternalism, feudalism and racism manifest themselves as important aspects of the ethos. The social disintegration which is endemic in this ethos is not caused, but merely accelerated by external impulses. The analysis indicates how, as a result of the specific organization of the narrative material, the text questions the feudal status quo. A process of demythologising of the vroegre boere-paradijs is therefore already present in the earliest Boerneef texts. However, the examination of Boerneef's prose also indicates that these texts go beyond the socio-politico-economic aspects by encoding the existential aspects of man's existence. , Hierdie proefskrif is die vers lag van 'n "rereading" (in die Barthesiaanse sin) van Boerneef (Izak Wi lhelmus van der Merwe 1897- 1967) se bundel Boplaas (1938). Die prosa van Boerneef word verken met spesifieke toespitsing op die een bundel . Die bundel-eenheid word ondersoek en tekstuele leidrade wat geledinge met ander tekste in die oeuvre aandui , word gevolg. Hierdeur word aangetoon hoe die betekenis en die be-tekenisprosesse van die tekste onderling, en die bundel as 'n geheel, op transtekstuele samehang berus. In hierdie leesproses word nagegaan hoe, deur middel van die ontginning van die tekstuele elemente, 'n Boplaas-kode in die narratiewe proses tot stand kom. Hierdie Boplaas-kode beteken 'n Boplaas-ruimte asook 'n Boplaas-etos. Paternalisme, feodalisme en rassisme word as belangrike aspekte van hierdie bestel geenkodeer en die tekste toon aan dat sosiale versplintering endemies aan die betrokke orde is en slegs deur impulse van buite verhaas word. In die bundel-analise word aangetoon hoe, as gevolg van die organisasie van die vertel stof, hierdie bundel bevraagtekenend ten opsigte van die feodale status quo staan. As gevolg hiervan is daar dus alreeds in die vroegste prosa van Boerneef 'n demitologisering van die "vroegre boere- paradijs" ingebed. Die ondersoek toon egter ook aan dat die Boplaas-tekste by die sosiopolitiko- ekonomiese dimensies verby óók die eksistensële aspekte van die mens se betstaan be-teken.

  • Description: An investigation into the quality of surface water and ground water was conducted during 1988 in the 38,8 km² Hout Bay River catchment near Cape Town. The main objective of the study was to determine those areas and activities which constitute a pollution source and to ascertain the relative proportion which each contributes to the pollution problem and health risk of the surf zone of the beach at Hout Ba . The objective was achieved by monitoring the chemical and microbiological attributes of the Hout Bay River, its tributaries and stormdrains in wet and dry conditions on a routine basis and during storm events. Hout Bay is a rapidly developing residential area in which sewage disposal occurs by means of septic tank soakaway systems. Ground water quality was monitored to investigate the contribution to contamination by septic tank effluent. Results showed that stormdrain effluent in dry and wet conditions and surface runoff during rainfall were the main vectors of pollution. Although the pollution concentration was high during dry conditions the greatest pollution discharge to the surf zone of Hout Bay occurred during storm events. In view of the proposed residential development it is imperative that pollution control measures be undertaken so as to secure the future recreational and aesthetic value of Hout Bay

  • Description: Emphasis in the study is on the prevalence of poverty especially in the so called third world developing countries. Poverty as a social problem is caused by a number of factors, viz: Over population, unemployment, illiteracy, etc. In the case of the study the focus is the rapid population growth or "population explosion" as it is commonly known. Family planning is sen as important, but not the only strategy in combatting the interrelated problem of population growth and development. The relevance and importance of social workers, as members of a multidisciplinary team in the delivery of family planning programmes is emphasised. There is evidence in the study to support the observation that Black African people in particular are reluctant to use family planning methods. Based on this evidence, the basic assumption arrived at is that there is a general unfavourable attitude to family planning in the Taung area. The research design used is exploratory-descriptive. Of the 75 areas in the district, 10 areas were included In the investigation. A stratified random sample was used, with a sample size of 200 respondents. The interview schedule was used to collect data. It was structured and consisted primarily of close-ended questions, and was analysed using the Biomedical Data Programme (B.M.D.P.). The problem is formulated from literature concerned with population growth in the Republic of South Africa as well as Bophuthatswana. The following sub-problems were described: illegitimacy; health and economic problems associated with large families; abortion; malnutrition and malnourishment; and the absence of services of the National Family Planning Programme In the Taung area. Compatibility between social work and family planning is a central concern, with community development as a significant method of intervention. The three important concepts in the study were broadly defined, viz: Overpopulation, family planning and attitude. It was established that: -the use of family planning follows rather than precedes the process of modernisation and rising economic standards; -no family planning programme can be practised universally - because of factors such as culture, need and habit. Attitudinal change is considered based on the basic assumption arrived at. Little has been done on the subject of family planning in south Africa. With regard to the role of social work in family planning, there have been impediments along the following lines: lack of firm tradition; emphasis on treatment rather than on preventive work; a view of family planning asa health measure and to be offered solely in the medical and health services. To be active in this field social workers need formal education and training. Taung: - the area of study is predominantly rural with almost all characteristics of rural areas, those of: Irregular transport services to and from remote areas; corrugated roads; primitive sanitary conditions; poor communication system; absence of electricity in villages; illiteracy and unemployment. On the other hand, development is evident especially in the health, education and welfare fields. The central findings in the study are those arising from resistances to family planning usage - politically; culturally; morally and psychologically. The general conclusions are: The high rate of unemployment is present in the sample and there is financial dependence on partners (men); the importance of social workers in family planning is emphasised; there is a desire to have large numbers of children (children feature prominently in the area and are regarded as an asset in various ways); and lastly, improved education does lead to an increase in motivation to adopt family planning practices. Against the highlighted findings, recommendations were made, viz that: Community development be used as a strategy for change; social workers be involved as team members in family planning - in policy formulation and planning of population programmes at various levels, using different methods of intervention; paramedical aides beused - because of inter alia shortage of qualified manpower and lastly formal education and training to be granted to prospective change agents in family planning delivery programmes. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

  • Description: Solanum mauritianum Scop. (bugweed), a serious exotic weed in South Africa, supports a depauperate herbivore fauna relative to indigenous Solanum species. These comprise mainly polyphagous, and some oligophagous, species. The greater diversity of insect herbivores on Solanum hermannii Dun., relative to other indigenous Solanum species in the eastern Cape, suggests that the plant is indigenous and not exotic as has been suggested. Five oligophagous species seasonally caused a high incidence of damage to S.hermannii and other indigenous Solanum species in the eastern Cape, during the study period. Galls of the flowers, stems and leaves of some indigenous Solanum plants are described and biological data on the gall-formers and their natural enemies presented. The tortoise beetle, (Chrysomelidae), defoliates a Conchyloctenia tigrina wide range of indigenous Olivo Solanum species. The exotic S.mauritianum and S.elaeagnifolium Cav. were unfavourable for growth and survival. S.hermannii proved the most favourable of the indigenous hosts tested, for growth and survival, providing further evidence that it is indigenous. Extensive studies on different field populations of the beetle revealed no evidence of host adaptation (host races). All populations tested displayed greater fitness when reared on S.hermannii. South African Solanum faunas are characterized by a scarcity of endophagous and monophagous herbivores, vacant feeding niches and low numbers of species relative to other plant taxa. This may suggest evolutionary immaturity of the insect-plant associations, although comparative studies of solanums from other parts of the world are needed for confirmation. Alternatively, these characteristics may simply be a feature of the genus Solanum in general. The depauperate herbivore fauna of S.mauritianum reflects a lack of local herbivores suitably preadapted to overcome its defences. This appears to be accentuated by absence of any close relatives of bugweed in South Africa. The greater diversity of herbivores in its native South America suggests that biological control may be a potentially useful means of control for bugweed. The potential for biological control is, however, threatened by the susceptability of the cultivated eggplant (Solanum melongena L.) to attack by Solanum-feeding insects. Possible solutions to this problem are discussed

  • Description: One of the most significant features of this year has been the employment of the four new people by CECS. Having so many new people in influential positions can be potentially dangerous for an organisation such as CECS which is rim along democratic lines. It thus becomes incumbent on the members of CECS to be vigilant against too much of the responsibility for the running of the organisation resting on the shoulders of the employed staff. Members should actively participate in decision-making so that it is they who determine the course of CECS. Each and every member should view themselves as an indespensible part of CECS, and that they share in the responsibility for the successes and failures of the organisation.

Cognitive restructuring through guided imagery : lessons from Gestalt therapy

  • Description: [Summary] In this chapter, a guided imagery method used in gestalt therapy was described in detail and analyzed into its specific components. The basic principles underlying the imagery work were shown to be analogous to those upon which standard cognitive therapy is founded, and this was illustrated by means of case examples, first from one of Perls' dreamwork seminars and then from the author's case files. It was shown how the method could be used to elicit the idiosyncratic meanings of the client in relation to a specific theme and to identify core dysfunctional assumptions. Illustrations were given of specific techniques that could be employed to challenge and restructure these cognitions. The benefits of the imagery modality are that it provides: (1) access to cognitions underlying emotional responses that may be difficult to identify through questioning, (2) a holistic presentation of networks of beliefs, and (3) a means of keeping the client in contact with avoided painful affect. Once a good conceptualization of the client's problem has been achieved, guided imagery provides a modality within which specific strategies for cognitive restructuring can be facilitated through guided discovery. Therapists who are willing to explore this modality and find an aptitude for it will be gaining access to something that will greatly enrich their potential for helping and can provide exciting avenues for developing their own creativity in the challenging work of enabling clients to identify and free themselves from dysfunctional personal meaning systems.
