- Description: Karoo volcanics of both mafic and felsic composition cover large areas of southern Africa, and are characterized by considerable ranges in their initial 87Sr/86Sr (i.e. Ro) ratios. Mafic volcanics from the eastern and western continental margins show the greatest range in Ro ratios, i.e. Lebombo-Nuanetsi area: 0.7035-0.7134 and Etendeka: 0.7030-0.7135 respectively. In the Central Karoo area the mafic rocks show a smaller spread of ratios: 0.7046-0.7094.

- Description: The early history of South African industrial development has been approached from essentially two angles. One body of thought has concentrated on the adverse effect colour bars have had on the development of South Africa. It is argued that racial discrimination in industry originated from the racial prejudice of white workers and from state intervention in the economy. Opposed to that view is the interpretation that the colour bar originated out of the specific character and subsequent development of South African capitalism. This study approaches the debates and arguments through an analysis of the Wage Act of 1925. The industrial relations system which operates in South Africa has its origins in the legislation of the 1920s. It is based on the Industrial Conciliation Act of 1924 and the Wage Act of 1925. Very few systematic analyses of the Wage Act have been produced hitherto. Most commentators have focussed on single aspects of the Act, but very few have attempted an examination of the operation of the Wage Board which was established by the Act. The Wage Board was instituted as an element to promote the civilised labour policy in the private sector. Whereas the Industrial Conciliation Act operated to protect organised labour, the Wage Act concentrated on unorganised trades and sections of trades. Although empowered to investigate conditions in the mining industry, the Wage Board was never used to regulate wages in that industry under the Wage Act due to opposition from the industry. It was concerned solely with secondary industrial and manufacturing establishments because agriculture and domestic service were excluded from the Wage Act. The Wage Act was based on the principal of compulsory regulation. Determinations in terms of the Board's recommendations were binding on employees and employers alike. Complex procedures hampered the activity of the Board until 1930 when the Act was amended and simplified. The Board faced a great deal of opposition from manufacturers in its early years. But a cautious approach and the gradual implementation of determinations ensured that employers opposition soon changed to support when it became clear the Board was not an arbitrary one. The Board had to take a number of strict considerations into account. It could not recommend wages if its recommendation would affect the particular trade concerned adversely. It concerned itself with the promotion of efficiency in business, production costs, consumerism , the wasteful employment of labour, the length of the working day and the productivity of employees. As such it was used as a means to assist the necessary rationalisation and reorganisation of South African industry. It could not recommend wages without the Minister's express instructions if all the employees covered by a reference could not receive a civilised wage . Civilised wages were classified as wages at which employees could enjoy white standards of living. This clause effectively introduced a colour bar into wage determinations. It operated before 1930 to buttress Industrial Council Agreements to prevent the displacement of whites by Africans at lower rates. The Wage Board also considered investigations from unskilled, African workers. The Board was not permitted by law to discriminate against people of colour. Apart from the potential colour bar of wage regulation in general in South Africa, the Board was instructed in 1930 to refrain from issuing recommendations for African workers. Regulations were also altered to exclude Africans. The Wage Act declined in importance after the Great Depression as white workers were drawn closer to the wider-reaching Industrial Conciliation Act. The need to regulate African wages and to control African labour became more evident during the period of economic expansion in the 1930s. The Act was replaced in 1937 and the restrictions formerly placed on Africans were removed. The workforce had finally been separated with the provision of different industrial relations appartuses." "...Every industrial and commercial centre in England now possesses a working class divided into two hostile camps, English proletarians and Irish proletarians. The ordinary English worker hates the Irish worker as a competitor who lowers his standard of life. In relation to the Irish worker he feels himself a member of the ruling nation and so turns himself into a tool of the aristocrats and capitalists of his country against Ireland, thus strengthening their domination over himself. He cherishes religious, social, and national prejudices against the Irish worker. His attitude towards him is much the same as that of the 'poor whites' to the 'niggers' in the former slave states of the USA. The Irishman pays him back with interest in his own money. He sees in the English worker at once the accomplice and the stupid tool of the English rule in Ireland. This antagonism is artificially kept alive and intensified by the press, the pulpit, the comic papers, in short, by all the means at the disposal of the ruling classes. This antagonism is the secret of the impotence of the English working class, despite its organisation. It is the secret by which the capitalist class maintains its power. And that class is fully aware of it." Marx to Siegfried Meyer and August Vogt April 9 1870 Marx and Engels Ireland and the Irish Question.

- Description: In 1980 the cape Education Department launched a Gifted and Talented programme in some schools which was intended to enrich the educational experience of the more able pupils. Numerous studies have shown these pupils to have a higher level of career maturity than non-gifted pupils, but the studies have also shown that these pupils face unique career- development problems. Gifted and Talented pupils constitute an important source of manpower and their potential contribution to the total society is great. Consequently they are in need of effective career guidance to help them overcome their unique problems and realize their potential. This study set out to discover if the career maturity of a group of Standard 9 Gifted and Talented pupils, identified according to the original Cape Education Department criteria, is indeed higher than that of their peers and to make recommendations for facilitating career education among these pupils. Contrary to expectations the Gifted and Talented pupils did not show significantly higher levels of career maturity than their peers, as measured on the Attitude Scale of Crites ' Career Maturity Inventory. Compared with the American norms , the scores obtained by the research population were unfavourable. The validity of the I .Q. scores used and the criteria for identification of Gifted and Talented pupils are seen as questionable which could have led to an inaccurate grouping of the pupils as Gifted and Talented or non- gifted. Recommendations are made for a basic career education programme for all pupils which would include periods of active work experience. Recommendations for additional career education for those currently classified as Gifted and Talented pupils are also made, so as to allow these pupils additional time for self- development, decisionmaking and dealing with their unique life situation

- Description: Outcrops of the Jurassic Karoo basalts and dolerites in central South Africa are remnants of an intracratonic continental igneous suite whose volume probably once exceeded 1.5 x 106 km³. Basic rocks with 6-8% MgO, 50-55% Si02 and Mg-number = 53-67 are overwhelmingly dominant in the Central area suite. Application of discriminant analysis to a data set of major and trace element analyses of the basic rocks confirms field and petrographic evidence that a number of compositionally distinct basalt magma types exist in the Central area.

- Description: Aspects of the life history of Myxus capensis which were likely to be most affected by man-induced habitat changes, were studied in the eastern Cape. Myxus capensis was found to be specialized for a catadromous life history. The fry migrate into freshwater reaches of rivers within a few months of being spawned at sea and return to an estuarine or marine environment when maximum size has been attained and large energy reserves necessary for spawning have been accumulated. Myxus capensis penetrates considerable distances up eastern Cape rivers and although present in the upper reaches of some estuaries, is only common in freshwater-dominated systems. Myxus capensis has adapted its life history style in a number of ways to overcome the constraints associated with the spatial separation of the freshwater feeding areas and the marine spawning grounds in a region prone to droughts and erratic river flow. Research on the more estuarine-dependent Mugil cephalus, which is also found in the freshwater reaches of eastern Cape rivers, enabled useful comparisons to be drawn. As the latter species is not dependent on a freshwater phase in its life cycle, it is subject to different selection pressures. This comparative approach gave insights into the adaptive significance of the life history tactics of Myxus capensis. Myxus capensis displays a number of life history tactics characteristic of migratory fish species which are thought to increase population fecundity by increasing the number of large females and hence maximizing egg production. These include a sex ratio in favour of females, faster female growth, females remaining longer in the freshwater feeding areas and reaching a larger ultimate size. Possible adaptations to the periodic isolation of the feeding and spawning areas include: (i) the development of ripe gonads only in estuarine or marine areas when access to the spawning grounds is ensured; (ii) year-round spawning and hence recruitment which enables the erratic floods to be used at any time for downriver spawning migrations and reduces the chances of total recruitment failure due to short-term adverse environmental conditions and (iii) a relatively wide range of size and age at first (and final) sexual maturity (2+ to 5+ years); this tends to ensure successful reproduction and recruitment in spite of a series of poor years, as well as dampen population fluctuations after long periods of isolation in fresh water. The dependence of Myxus capensis on the freshwater reaches of eastern Cape rivers makes this species vulnerable to man-induced habitat changes. The erection of barriers to migration has cut off large stretches of suitable habitat and almost completely eliminated Myxus capensis from certain rivers. This detrimental effect has been largely responsible for the recent inclusion of this species on the Red Data list of endangered fish species in South Africa. This study demonstrated the considerable fisheries potential of both mullet species and this should ensure that their conservation and wise utilization be given high priority. Management proposals include: (i) the netting and lifting of Myxus capensis over barriers to migration; (ii) the construction of fish ladders when feasible and (iii) the artificial propagation of this species to enable large-scale stockings of existing man-made impoundments as well as natural habitats to be carried out. It is predicted that the life history characteristics of Myxus capensis, which evolved in response to an erratic freshwater environment, should ensure that when man-induced habitat changes are rectified, this species will again flourish in eastern Cape rivers.

- Description: This thesis analyses the effects of relative market share and the rate of market growth on the strategic characteristics and financial performance of selected companies quoted on the Johannesburg Stock Exchange over the period 1977 to 198. It is well established that business performance is partially contingent upon relative market share position and the rate of market growth. Together these variables comprise the basis of the Boston Consulting Group approach to portfolio analysis in the form of the Boston Consulting Group Growth/Share Matrix. A methodology was designed to test the validity of this matrix in measuring and predicting corporate behaviour at the business level in South Africa. Selected companies were placed into the matrix and analysed in terms of their strategic attributes (represented by selected financial ratios) and their level of performance (represented by a wide range of financial performance measures). The research findings show that relative market share and the rate of market growth have a significant impact on the strategic attributes and financial performance of South African businesses. Also, certain attributes are closely associated with particular types of performance. Therefore, given a specific performance target, management should ultimately be able to isolate and monitor the relevant strategic attributes in ensuring that the target is achieved. The analysis of contingent models of strategy is still in its infancy, but this study indicates that the field is possessed of great potential.

- Description: Résumé: Heteronomous host relationships are unique to parasitoids in about 8 aphelinid genera. Males have host relationships quite distinct from those of their females. Females of ALL species are primary endoparasitoids of homopterous hosts. Males, on the other hand, may be either primary ectoparasitoids of the same host species as their conspecific females, or they may be hyperparasitic upon parasitoids within Homoptera, and some are primary endoparasitoids of moth eggs. Species in these groups are termed DIPHAGOUS PARASITOIDS, HETERONOMOUS HYPERPARASITOIDS and HETEROTROPHIC PARASITOIDS, respectively. The selective advantages proposed to explain the evolution of these unusual host relationships are examined in this thesis. The biology of a diphagous parasitoid was examined in detail because diphagous parasitism is considered the most primitive of heteronomous host relationships. Diphagous parasitism is thought to have evolved during a period when ovipositing females continuously encountered large proportions of parasitised hosts. Larval competition may have generated the selection pressures that favoured male ectoparasitism. Ectoparasitoids are known to be superior in competition against other larvae, even older ones. A series of observations was carried out on the diphagous parasitoid, Coccophagus bartletti. Information was gathered on oviposition and host-feeding behaviour, daily activity patterns, and sex ratios in the laboratory and field. This enabled the design and interpretation of a series of observations on the responses of mated C. bartletti females to already-parasitised hosts. The results indicate that competition from other parasitoids probably played no role in the evolution of diphagous host relationships. Heteronomous hyperparasitoids, thought to have evolved from diphagous parasitoids, appear to be strong competitors because their males kill other parasitoids. However, an alternative hypothesis to the competition one, and based on the present study, is presented. Implications for the generally-held view, that competition is important in moulding species' characters, are discussed.

- Description: The Grahamstown clay deposits extend in a broad belt from 26°23 to 26°50 East longitude and from 33°15 to 33°22 South latitude along two distinct geomorphological features, the Grahamstown Peneplane (650 m) and the Coastal Plain (520m). The clay deposits traverse four different lithologies including the Bokkeveld Shale, Witteberg Shale, Dwyka Tillite and Ecca Shale. The two planes invariably have a covering of silcrete which is also present over most of the clay deposits except where erosion has taken place. X-ray fluorescence analysis shows that chemically there is a fairly wide variation between and witnin the deposits. The greatest variation is in the Si0₂/Al₂0₃ ratio which appears to be controlled by the parent lithology and to some extent by the amount of leaching. K²0 shows an increase in concentration with depth and therefore indicates the limits of hydrolysis and leaching and of the clay. X-ray diffraction study shows the Peneplane and Coastal Plain deposits to be quite distinct. The Peneplane deposits consist of kaolinite, illite and quartz and the Coastal Plain deposits of kaolinite, illite, quartz and pyrophyllite. The presence of pyrophyllite is not fully understood as there is no indication of major faulting, metamorphism or pyrophyllite in the parent rock. The pyrophyllite most probably represents a transformation product of kaolinite. The kaolinite from the various deposits shows a considerable variation in crystallinity in both the X-ray diffraction traces and electron photomicrographs. The most poorly crystalline kaolinites are from the Coastal Plain deposits and the difference in crystallinity is most probably due to differences in the degree of hydrolysis and the parent rock material in the case of the tillite. Genetically all of the deposits are residual types generated by hydrolysis and subsequent leaching of micas and feldspars. The principal elements leached are silicon, iron and potassium. The hydrolysis and leaching took place over a long period of time in the flat lying areas of the Peneplane and Coastal Plain. The deposits are exploited economically and the clay is used principally in the tile, pottery and whiteware industries with some usage in the paper, refractory and brickmaking industries. The price commanded by raw kaolin is not very high and as a result the clay industry in Grahamstown is not as viable economically as it could be.

- Description: Hakea sericea is a shrub, introduced into South Africa from southern Australia, that is now invading the indigenous "fynbos" vegetation in the Cape mountains. Presently an area of 480 000 hectares is affected. One of the main factors contributing to the success of H. sericea as a weed is its copious seed production. The seeds are accumulated on the plant throughout its life-time. When the plant eventually dies, usually after a fire, the fruits dehisce and all the seeds are released within the space of a few days, resulting in seed densities of up to 7 500 seeds per m². Dense, impenetrable stands of H. sericea develop which suppress the indigenous vegetation. Apart from the labour intensive mechanical clearing of H. sericea, biological control appears to be the only other means of control. This study deals with the post-release evaluation of the effectiveness of the first successfully-established, biological control agent, the hakea fruit weevil, Erytenna consputa. Most of the damage is done by the larval stage of the weevil which attacks the young developing fruits, thereby reducing seed production.

- Description: From Conclusion: For the sake of posterity and historical research, our need for secure origins and our appreciation of and pleasure in fine craftsmanship and art, it is important that any Art Collection, particularly an Historical one, be fully documented. All data pertaining to the pictures should be recorded from an artistic, historical and even scientific point of view and photographs should be taken of the pictures. An organized classification system, the correct registering and labeling of each picture and its accessioning and cataloguing as part of the contents of the Gallery and for visitors information, should be constantly 53 maintained and where necessary and in as many ways as possible, cross-references made so that the stored information be usable. To this end and with the growth and increasing importance being placed on Art Museums and Galleries in the community it would probably be of value to cross-reference with other similar institutions and in the respect and day and age, it is not unrealistic to propose that the King George VI Art Gallery consider a computer cataloguing system to facilitate research and complement a more simplified version for the use and guide of the general viewing public . The significance of a picture is not only its value as such, but also the information relating to it. The importance of the Historical Collection as Africana and works of art, expressive of the places, events, people and even attitudes, and as cultural and historic items, goes without saying. Without the Historical Collection of the King George VI Art Gallery, Port Elizabeth, the Eastern Cape community and South Africa too, would be the poorer. The pictures have their role to play .

- Description: The Hex River Valley is one of the main centres in South Africa for cultivation of table grapes of export quality. The vines require irrigation water, which must be low in dissolved solids. Approximately two thirds of the annual irrigation requirement is obtained from boreholes and the balance from surface water sources. During the early 1960s a deterioration in the quality of the groundwater was noticed, becoming critical in some areas, and borehole yields also declined. The main objectives of this study were therefore to obtain an understanding of the hydrogeological and hydrogeochemical processes operating in the valley to explain the derogation of the groundwater resource and enable optimum utilisation and management of the resource in the future. To achieve these objectives, field work involving exploration drilling, aquifer tests, hydrocensus, long-term monitoring of groundwater levels and surfacewater flows and extensive sampling of the ground and surface waters was carried out. Analysis of these data gave quantitative information on groundwater occurrence, aquifer hydraulic properties, groundwater recharge and storage, chemical characteristics of the ground and surfacewaters and sources of dissolved species. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: The Karoo rocks are amongst the earliest manifestations of igneous activity accompanying the break-up of Gondwanaland during the early Mesozoic. Remnants of the once extensive lava sequence and the associated dolerite sills are found throughout southern Africa south of latitude 150S, the present outcrop being ca. 140,000 km². The main peak of volcanic activity is dated at about 190 m.y. and is probably coincident with the earliest stages of the opening of the Indian Ocean by the separation of Antarctica from southern Africa.
