  • Description: This thesis examines the opinions of a sample of partners in accounting firms within the Republic of South Africa on the advertising of professional accounting services. The advertising of professional accounting services has become a highly contentious and complex topic. This thesis identifies eight issues related to the topic and examines the partners' opinions on these issues. In addition, the partners' opinions are examined in relation to the possible placing, means and methods of advertising of professional accounting services as well as the possible content of advertisements for professional accounting services. A methodology was designed to obtain the opinions of partners from all provinces of the Republic, from varying sizes of accounting firm, of varying ages and experience, and from both official language groups. The opinions were then analysed . The research findings show that a number of major differences of opinion exist within the profession, and that generally the present rules and regulations pertaining to advertising are in need of revision. This thesis makes a number of recommendations for revision as part of what should be an ongoing process. This thesis is only part of what needs to be done in this field. A great deal more research is imperative if a satisfactory set of rules and regulations for the advertising of professional accounting services is to be maintained.

  • Description: From introduction: In this thesis some of the economic theory underlying the application of cost-benefit analysis to education is considered with the view to discussing its relevance to the field of educational provision for Black people in South Africa. The fact that educational facilities available to Blacks are so vastly inferior to those of the Whites has given rise to virtual consensus that more has to be provided for the Black population. The economic implications of education are frequently cited to support this viewpoint. Using (a ) the theoretical bases established in chapters 1 and 2, (b) the review of the rate of return to education studies in chapter 3 and (c) the broader socio-economic considerations introduced in chapter 4, it is concluded that this viewpoint is not necessarily well founded in South Africa and that the potential for greater use of the techniques described, is far from exhausted.

  • Description: An autecological study of the heterosporous fern Azolla filiculoides Lamarck and its endosymbiotic blue-green alga Anabaena azollae Strasburger, based on a combination of field and laboratory studies, is presented. The taxonomy, morphology and anatomy of the fern-alga association were studied as well as nutritional and physiological aspects of the symbiosis. These studies have defined the habitat and nutritional requirements of the fern and have provided new insights into its reproductive biology, nitrogen metabolism and the nature of the association between the fern and alga. In the catchment area of the Hendrik Verwoerd Dam the availability of suitably sheltered habitat limits the distribution of A. filiculoides while the availability of nutrients, in particular calcium, phosphorus and iron, limits the growth of the fern. The multilayered mats formed by A. filiculoides are essential for spore production, cause dramatic changes in the hydrochemistry of the underlying waters and confer a great competitive advantage on the plant. Methods for the isolation of the fern and algal components of the symbiosis have been developed but recombination of the individual organisms to reform the symbiosis was unsuccessful. The development of the fern is closely linked to that of the alga and the association is maintained throughout the life cycle of the fern. Because of its specific habitat and nutritional requirements, A. filiculoides is unlikely to colonize the open waters of the Hendrik Verwoerd Dam.

  • Description: The biology of three large cyprinid fishes, Barbus holubi, B. kimberleyensis and Labeo capensis, was studied in a large turbid man-made lake on the Orange River, South Africa. The influence of environmental fluctuations on population dynamics was examined in relation to biological adaptations. On this basis inferences were made about the effect exploitation would have on the populations, and management alternatives were considered. Lake Ie Roux is situated in a semi- arid area, downstream from another large reservoir, Lake Verwoerd. In the pristine river, flooding is seasonal, and floodwaters carry a heavy silt load. Lake Verwoerd acts as a silt-trap and changes in turbidity in Lake Ie Roux (Secchi disc readings range from 15 to 160 cm) are influenced by hydrological management and are not necessarily seasonal. Water temperatures in the regulated river connecting the two lakes depend on the pattern of water release, and fluctuations in Iake levels depend on management practices. Reproduction was studied by examination of gonads and from the distribution of newly hatched juveniles. Age and growth was interpreted from the reading of scales and otoliths. Relative year class strength, dispersal and mortality were monitored using catch data from a regular, standardized gillnetting survey. The Barbus species spawn in the regulated river in spring or summer. Spawning is coordinated for a large part of the population and B. holubi spawn four to six weeks earlier than B. kimberleyensis. The juveniles are 'initially found along the shoreline, but later move into the pelagic zone and disperse throughout the lake. Year class strength is dependent on time of spawning and a late spawning results in a poor year class. For this reason, year class strength of B. kimberleyensis is generally poor, but there is a greater variation in year class strength of B. holubi, which is the dominant large Barbus. The two Barbus species exploit the pelagic zone, visually predating on zooplankton. When turbidity increases large scale mortalities occur, especially in B. holubi. Mortalities more than compensate for the reduction in carrying capacity, and the size of the reduced population may be inversely related to initial abundance. Growth rate is similarly affected by turbidity and density, and size at sexual maturity in B. holubi is reduced when growing conditions deteriorate. Labeo capensis do not form a homogenous population in Lake le Roux. Spawning occurs throughout the lake, but is erratic, probably depending on local rainfall. At each locality, more than one spawning may occur during spring and summer because of temporal variation in gonadal development. Juvenile survival appears to be mainly dependent on water level fluctuations, and strong year classes were formed when the lake was filling during the first two years. Subsequent year classes were weak. Subadult and adult B. capensis are herbivorous and depend on autochthonous production for food. They are relatively sedentary, but when turbidity increases fish smaller than 200 mm disperse, probably in response to food shortages. Mortality rates may be accelerated but mortalities are not as high as in B. holubi. The growth rate of B. capensis is variable and depends on turbidity and population density. Size at sexual maturity remained relatively constant during the study period. B. holubi has a relatively fixed reproduction cycle in Lake le Roux and exploitation is likely to dampen fluctuations in population density. Population growth and stability could be further promoted through hydrological management. B. kimberleyensis does not represent an exploitable population in Lake le Roux, although the large size obtained by this species (>3 kg) may be an attraction to anglers. B. capensis does not appear to have the potential to withstand sustained exploitation because of its erratic and generally poor reproductive success. However, the species is long-lived and can sustain relatively high densities under harsh conditions because of its relatively low mortality rates. It was concluded that harvesting of B. holubi must be flexible to promote maximum benefits to commercial and recreational fisheries, but B. capensis which is not an angling species, should chiefly be exploited when catches of B. holubi are poor, but left to recover in between. An alternative management strategy would be to commercially exploit the fish populations of several reservoirs. A monitoring programme could be established to decide when each reservoir is to be exploited to see to the interests of commercial and recreational fishing alike.

  • Description: The biology of the lesser sand shark, Rhinobatos annulatus, was studied off sandy beaches in Algoa Bay over a period of two years. Tagging studies, due to low numbers tagged, did not reveal major movements. However, comparison of numbers of sand sharks caught off the beach and deep water during summer and winter months suggested that migration occurred during these seasons with the animals being inshore in summer. Annual rings on the vertebral centra were used to determine age. Both sexes can reach a maximum age of seven years. Conventional growth curves could not be fitted and empirical curves were used to illustrate growth. The reproductive cycle was investigated and indicated that both sexes matured after three years of age. The breeding season was during late summer when the shallow water was utilized as a nursery area. The sand shark is an aplacental viviparous species with a gestation period of 10 months. Breeding occurred every year and fecundity increased with total body length to a maximum litter size of 10 young. The most important prey items taken inshore were the mysid Gastrosaccus psammodytes, the prawn Macropetasma africanum, the crab Ovalipes punctatus and the sand mussels Donax spp. Differential predation by different length classes of sand shark resulted from a dynamic zonation of these different size classes in the surf zone. Smallest individuals fed closest inshore. Seasonal variation recorded in the hepatosomatic index was primarily due to the accumulation of hepatic lipids. This variation showed significant correlations with the breeding cycle in adult sand sharks. The contribution of liver lipids to the formation of egg yolk was estimated and found to be secondary to lipid reserves for maintenance. Liver colour varied depended on the amount of liver lipids. Ancillary observations were made of other elasmobranchs in the surf zone. , Thesis (DPhil) -- Faculty of Science, 1983

  • Description: The grade of a mineral deposit is determined by the effectiveness of a geological ore forming process, which is the result of the interaction between an ore forming mechanism and the environment in which it operates. Properties of a mineral deposit controlled by ore forming processes include the distribution, density and nature of ore minerals and gangue, and the metal content and impurities of the ore minerals. More efficient ore forming processes tend to develop in the larger mineralizing systems giving rise to richer deposits. As the geological environment within which a mineral deposit evolves becomes more complex a greater number of variables interact to determine the grade of the deposit. This is reflected in the greater variability of the grade distribution, resulting in greater difficulties in obtaining reliable estimates of the recoverable grade, and increased difficulties in the processing of ores. In response to economic fluctuations the working grade of heterogeneous orebodies, that form in geologically complex environments, can often be altered to ensure the continued viability of a mining venture. In contrast the evenly mineralized orebodies that tend to develop in geologically simple environments do not have this flexibility. All the important decisions in the mining industry, such as feasibility studies, choice of ~ining and processing methods, selection and planning, are made on the basis of, or are related to, grade estimates. If the geological controls of grade are fully understood, then it is possible to optimize the selection of the various mining alternatives, leading to the efficient exploitation of ore deposits.

  • Description: The aim of the study is to broadly assess the demand for skilled and semi-skilled labour in the existing industries in that part of Region D of the Good Hope Plan comprising the Border corridor, the Ciskei and southern Transkei (hereafter referred to as the survey region). This survey region was chosen as the target area, since firstly, all of Region D's growth points are located within it and, secondly, technical training facilities in the survey region are recognised as being inadequate. This study does not aim to specify the type of technical training institution that should be established in the survey region; rather it analyses the demand-side of the regional labour market in order to identify the nature and extent of the perceived need for skilled labour. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

  • Description: My investigation of women artists and their status in society today as a result of the feminist movement, revealed issues which, I felt, were multifaceted. This necessitated an exploration of many aspects in order to arrive at a fairly satisfactory conclusion as to whether the revolt and the aggression on the part of the feminists had borne any fruit, either generally in everyday life, or artistically. It has proved most stimulating and informative. I think that the need to assess oneself as a woman, working within a male-dominated creative environment is a very necessary process and one which has been most beneficial to me. The subsequent research revealed that a radical, thematic change had occured within the feminist movement at the start of the Eighties; a fact of which, till recently, I was largely unaware. What I discovered was that the militant, feminist approach of the Sixties and Seventies had given way to a more realistic involvement brought on partly by the economic recession and the effects as well of earlier feminist movements, leading to a relaxation on the part of the younger generation. The Violence had faded. Hard times curbed the excesses of the movement and took it along the road to practicality. Dovetailed to this and seeming to run concurrently was the phenomenon of the demise of the Modern Art Movement. These changes described were not only artistic and feminist, but cut right across the board. involving all facets of life. To take one as an example. the political with conservatism reinstating itself in America not merely as an alternative but as a worthwhile direction in itself. Other issues included the sociological, historical, biological, and cultural; all closely interwoven and therefore requiring some generalisations at times. Previous to becoming involved with my topic, I had been reacting to pre-conceived ideas laid on me as a student in the Sixties and Seventies - a militant, aggressive approach acquired as a protective shield, to deal with the masculine environment which denigrated in varying degrees mine and fellow female artists work, sometimes overtly, sometimes subconsciously. This discrimination, is usually denied as ever having existed by the men involved. It shows a lack of awareness of what, we, as female art students, were subjected to. This is one of the main reasons why I undertook this subject; partly out of interest and perhaps partly as some sort of catharsis.
