Soeklig op die Klerksdorp-kompleks
F.J. Potgieter
Koers : Bulletin for Christian Scholarship , 1969, DOI: 10.4102/koers.v37i2.1302
Abstract: Al vyf blanke universiteite van Transvaal is op die een of ander wyse gemoeid met die beplanningsnavorsingsprojek in die Klerksdorpse gebied wat op die oomblik aan die gang is. Vir dié navorsing het die Staat R18,000 bewillig, verskillende myngroepe altesaam R6,000, en plaaslike owerhede R1,500. En in die komitee wat beheer oor die navorsing uitoefen, is twee staatsdepartemente verteenwoordig, afgesien natuurlik van die verteenwoordiging van die betrokke universiteite.
Geografie en sy verhouding tot beplanning
F.J. Potgieter
Koers : Bulletin for Christian Scholarship , 1967, DOI: 10.4102/koers.v35i2.1374
Abstract: As die geografie hom besig hou met die studie van die aarde as woonplek van die mens, soos die meeste geograwe waarskynlik aanvaar, is dit logies dat die klem in die vak van tyd tot tyd sal verskuif namate die mens se tegnologiese vordering enersyds verandering aanbring in die onderlinge verhoudings van die samestellende dele van die menslike omgewing, en andersyds in die steeds veranderende wyse waarop die mens die aarde bewoon.
Effect of different bedding materials on the reproductive performance of mice
F.J. Potgieter,P.I. Wilke
Journal of the South African Veterinary Association , 2012, DOI: 10.4102/jsava.v68i1.858
Abstract: Vermiculite, pine shavings and unbleached eucalyptus pulp contact-bedding were compared using the number of litters and individuals born and weaned, mortality rates at different stages of the lactation period, and the weight increase of pups as evaluation indices for bedding quality. These bedding materials exerted different effects on the reproductive performance of the same mouse strain. The same is true for the effect of a specific bedding material on different mouse strains. These effects are most pronounced during the first 4 days of life. As a whole, the results demonstrated that eucalyptus pulp was the better bedding type, followed by pine shavings and vermiculite. The latter material had a detri-mental effect on the mating success of AKR mice.
Onderwysersopleiding in Suid-Afrika: leersame aspekte van ander stelsels
J.L. van der Walt,F.J. Potgieter,C.C. Wolhunter
Koers : Bulletin for Christian Scholarship , 2009, DOI: 10.4102/koers.v74i1&2.118
Abstract: Teacher education in South Africa: noteworthy aspects from other systems Teacher education in South Africa, as part of the educational system, has been subjected to radical reform since 1994, as part of the reconstruction of society and of the education sys-tem. Deliberations about this aspect of the system have re-sulted in a number of significant policy documents and practical changes. The question arose whether South African theory and practice, with specific reference to teacher education, could learn in any way from the systems and practices of other countries. To find an answer to this question, a comparison of the teacher education systems of ten other countries and federal states including two developing countries and federal states, was made. The comparison, based on a particular philo-sophical-theoretical framework, revealed that the South African teacher education system compared well in theory and practice with the other systems. The study also revealed a few lacunae in both South African and foreign theory and practice.
Die intrinsieke verband tussen opvoeding en spiritualiteit
J.L. van der Walt,C.C. Wolhunter,F.J. Potgieter
Koers : Bulletin for Christian Scholarship , 2008, DOI: 10.4102/koers.v73i1.150
Abstract: The intrinsic relationship between education and spirituality After having researched the phenomenon of (especially young) people turning their backs on mainstream religions and finding refuge in “new” forms of spirituality, the authors concluded that, as always, the education of children cannot be done justice to unless attention is also devoted to the development of their spirituality. To defend this contention, they firstly analyse religion as a phenomenon. They find it to be multi-layered, with spirituality forming the innermost layer. They then discuss the emergence of “new” forms of spirituality and find them to be alien to the Biblical concept of spirituality. After discussing the intrinsic link between education and both the “new” and the Biblical forms of spirituality, the authors find their initial conclusion to have been vindicated.
Die akademie in Suid-Afrika: ’n vervullende professie?
J.L. van der Walt,C.C. Wolhunter,F.J. Potgieter,P. Higgs
Koers : Bulletin for Christian Scholarship , 2009, DOI: 10.4102/koers.v74i3.132
Abstract: Academe in South Africa: a fulfilling profession? South African academics possess a collective value system. However, other value systems impact not only on their value system but also on their academic work. They typically find themselves working in an institutional, a national and an international context, each with its own hierarchy of values. A theoretical discussion of (the role of) values in the academic workplace is followed by an overview of the professional values held by South African academics as measured by means of the Changing Academic Profession (CAP) Survey, which was carried out in 2008. The survey revealed, for instance, a rift between the institutional value hierarchy and that of the academic profession. It can therefore be concluded that many South African academics seem to lead relatively unfulfilled professional lives, among others, because they find themselves working in an environment (various contexts) with many contradictions. These problems should be addressed for the sake of the well-being of both the academic profession and of the higher education sector.
Learners' perceptions as to what contributes to their school success: a case study
K.C. Moloi,K.P. Dzvimbo,F.J. Potgieter,C.C. Wolhuter
South African Journal of Education , 2010,
Abstract: Some historically black schools manage to do quite well despite their circumstances, such as dire poverty. We aim at explicating some of the causal factors regarding the effectiveness of three schools in deep rural Mpumalanga, South Africa by tapping the perceptions of their learners. Data were collected from learner samples (four girls and four boys from each school, all of them black) by means of semi-structured focus group interviews. The results lead to the conclusion that the perceptions of disadvantaged black learners in this area, with respect to what contributes to their educational effectiveness, may also be understood in terms of hierarchical insights and awarenesses, the ontological basis of which seems to be successful pedagogical dialogue, with mutual acceptance as its fountainhead.

The use of ketamine in cancer palliation
F.J Smith
Southern African Journal of Anaesthesia and Analgesia , 2007,
Abstract: Cancer pain is caused by continuous tissue injury, which may be due to surgery, infiltration of the surrounding organs including nerves, as well as from mucositis after chemo- or radiotherapy. Nerve involvement, chronic opioid therapy and continuous nociceptive input cause hyperalgesia. Chronic stimulation of the dorsal root neurons leads to hyperalgesia and resistance (tolerance) to μ opioid analgesics (hyperalgesia-tolerance). The NMDA receptor antagonist ketamine reverses tolerance to morphine. Ketamine aggravates the sedative effect of opioids and other drugs used for neuropathic pain, such as sodium valproate and amitriptyline. The pain experienced by cancer patients needs a multimodal approach, including ketamine. Although ketamine appears to be a useful analgesic, the literature dealing with ketamine as an analgesic lacks randomised controlled trials.
Soil Patterns Associated with the Major Geological Units of the Kruger National Park
F.J. Venter
Koedoe : African Protected Area Conservation and Science , 1986, DOI: 10.4102/koedoe.v29i1.525
Abstract: The dominant soil types of the Kruger National Park and their interrelationships with parent material, topography and climate are discussed. The geogenetic and topogenetic nature of the soils are manifested in the strong correlations between recurrent soil patterns, major geological units and terrain morphology. The soils are categorised into seven major classes on the basis of the parent material from which they developed. General soil patterns within the major classes are discussed.
