- Description: The intention of this dissertation is to attempt to project the theoretical concept of Corporate (or Long-Range) Planning into the reality of one of South Africa's major motor vehicle manufacturing company's task environment. It is a sad fact that there are no universally - applicable practical planning "laws" (as are present within the discipline of, say, Physics) amidst the ever-changing hurly-burly world of modern commerce and industry. Accordingly, there are very real distinctions between distilled Corporate Planning theory, as it is propounded in the many available books and articles, and Corporate Planning practice as actually implemented. This is true largely by virtue of the fact that in the same way as persons differ in their physical and mental make-up, so too do individual companies; even to the extent of acquiring a distinct corporate "personality" of their own. Terms of reference, p. 1.

- Description: The objective of the thesis is to make a critical assessment of the performance of three relatively simple deterministic models of the rainfall-runoff process. The need to evaluate and compare deterministic models arises because of the large number of models which are available in the literature. A number of the available models would appear to be equally suitable for a given situation whereas many models are found to be valid only under the specific range of conditions for which they were developed. Therefore there is a need for guidelines to allow the most judicious selection of a model for a particular set of circumstances. The models used in the study will be tested in a semi-arid catchment to determine their applicability under ephemeral flow conditions

- Description: The compensation process is a complex network of sub-processes directed toward compensating people for services performed, and motivating them to obtain desired levels of performance. Among the intermediate components of this process are wage and salary payments, the awarding of other cost items such as insurance, vacations, sick leave, etc. (fringe benefits), and the provision of essentially non-cost rewards such as recognition, privileges and symbols of status. However, the broad subject of compensation in terms of cost to the organisation may be examined in two sections, namely, wage and salary administration, and fringe benefit administration. The compensation survey forms an integral part of both administration processes, and thus becomes a necessary and essential device in the determination of the final compensation package to the employee.

- Description: Studies on delinquency fall into two groups, a statistical orientation and a qualitative approach. This study adopted the latter approach using Maslow's theory to investigate the relationship between unmet needs and stealing. It also attempted to explicate the function of stealing for each individual and focused upon interpersonal and intrapersonal aspects. The Rorschach, Thematic Apperception Test and the Draw a Person Test were administered to four white male adolescents who had stolen. Their ages ranged from 14 to 17 years. An analysis of each test was completed focusing upon the needs of the individual. In addition the case history and impressions gained during testing were included. It was found that unmet needs had resulted in stealing. Their personalities displayed common characteristics but differences were also evident. A summary was provided and the implications for therapy were then discussed.

- Description: The study of landforms has, to a large extent been neglected by exploration geologists. This is surprising because field geology is intimately related with landforms of one type or another. An understanding of the geomorphological history of a particular area will assist in the appreciation of the surficial environment, the processes of weathering, soil formation and duricrust (calcrete , ferricrete silcrete) formation. This has direct application in planning and interpreting geochemical sampling programmes. In order to understand the evolution of landforms it is necessary to study slope development in some detail. Agents of erosion and denudation constantly at work, remove detritus from hillcrests down to the drainage lines which form the local base level from whence material is transported down to the sea. The system is one of dynamic equilibrium, and the concept of grade is important in understanding hillslope evolution. Thus Section (1) of this discussion deals with past and present theories of hillslope evolution. Very little work has been done recently on the geomorphology of Southern Africa and the presently accepted classification of land surfaces is based on the work of Prof. L.C. King (numerous publications). However, through the more recent work of De Swardt and Bennet (1974) on the geomorphology of Natal, it is apparent that the present system of landform classification in Southern Africa requires widespread revision. The relationship of erosion cycles in Southern Africa to the late Jurassic-early Cretaceous break-up of Gondwanaland has received insufficient attention in the past. Erosion cycles bear an intimate relationship to offshore Cretaceous and Tertiary-Recent sedimentation. Valuable information on these sediments has only recently become available as a result of offshore exploration for oil. The findings of De Swardt and Bennet (1974) are summarized in Section (2) and the present land surface classification of Southern Africa is reviewed. Finally, some suggestions on a new interpretation of land surfaces in Southern Africa are given.

- Description: A description of the geochemistry of tungsten is given. The geochemical properties of tungsten have a strong influence on its mineralogy, distribution and abundance in crustal rocks and rock-forming minerals , and its migration/deposition within the ore-forming and supergene environments. The behaviour of tungsten during migration, from source to site of deposition, within the crust is discussed in some detail and environments considered favourable to the concentration of tungsten ore minerals are suggested. All major types of tungsten ore deposit are described with emphasis placed on those of greater economic importance. Characteristic features of each type of deposit are particularly emphasized in order to provide clear guidelines to exploration. Hydrothermal, pyrometasomatic and stratabound tungsten deposits present themselves, economically, as the most important exploration targets. The recently developed concept of syngenetic stratabound tungsten mineralisation is outlined. Exploration for deposits of this type should be aimed predominantly, but not exclusively, at volcano-sedimentary sequences of Lower Palaeozoic age, particularly within regions known to contain occurrences of Sb and Hg. Tungsten deposits commonly contain concentrations of one or more of the following metals: Sn, Sb, Bi, Mo, Au and Ag. The presence and possible extractive value of these metals, together with commonly associated metal impurities such as As, must always be taken into account in a feasibility study , Adobe Acrobat 9.53 Paper Capture Plug-in

The activity of serotonin N-acetyltransferase, another pineal enzyme with a greater amplitude of circadian rhythmicity and which is under noradrenergic neural control, the degree of blockade depending on the selectivity and affinity of the agent used. An attempt was also made to alter the oestrous cycle of the rat by dosing with þ-active substances. Only propranolol had any effect on the oestrous cycle. It was not possible to establish an absolute link between the alteration in pineal enzyme activity and an influence on the oestrous cycle. It was concluded that the pineal enzyme studies are useful pharmacological means for evaluating þ-active substances

The aim was to design the system in such a way that it could be extended to cater for other classes of problems, so that eventually a system which could automatically generate program solutions for a range of problems might be developed.

- Description: From Introduction: Lakes, estuaries and man-made water impoundments can be considered as intervening basins which provide for the temporary storage both of sediment and of water. Because of the potential energy of soil in elevated positions and because of the kinetic energy of water flowing under the influence of gravity, eroded material is eventually transported to the lowest possible level, i.e. the ocean deeps, or some intervening basin. This denudation process may be compared with Newton’s second law of thermodynamics which states that each system tends to move in the direction of lowest energy. Sedimentation in intervening basins may be seen as part of the natural process of landscape evolution. The rates at which sedimentation occurs may be strongly influenced by the activities of man.

- Description: In 1843 a committee of the Colonial Bishroprics Fund appointed to investigate the state of the Church of England at the Cape of Good Hope, recommended the formation of a bishopric, and suggested that the bishop settle in the eastern districts of the colony, with an archdeacon in Cape Town. Three significant principles had been enunciated: the church was to grow under a bishop, the church would have a dual mission to blacks and whites, and the colony's eastern frontier, long a political and military headache, was seen as the focus of a new and spiritual battle. Contact between Nguni tribesmen and the eastward-moving European trekboer began in the region of the Fish River during the rule of the Dutch East India Company. Cattle and land were the main ingredients of the frontier conflict. From the point of view of the white settler, the growing cattle trade meant an increased need for pasture, but although the motive for expansion was economic, frontiersmen had come to regard large lands as their birthright. The semi-nomadic pastoral economy of the Nguni also required abundance of land, which was vested in the tribe. To the tribesmen, their cattle had a political, social and religious significance which transcended the economic. Cattle were sacrificed to the ancestors to propitiate the shades of the departed and to secure the prosperity of the tribe. The years of conflict, the constant threat to their herds and their land, undermined the basis of Nguni society, without providing it with a new foundation.

- Description: In 1843 a committee of the Colonial Bishroprics Fund appointed to investigate the state of the Church of England at the Cape of Good Hope, recommended the formation of a bishopric, and suggested that the bishop settle in the eastern districts of the colony, with an archdeacon in Cape Town. Three significant principles had been enunciated: the church was to grow under a bishop, the church would have a dual mission to blacks and whites, and the colony's eastern frontier, long a political and military headache, was seen as the focus of a new and spiritual battle. Contact between Nguni tribesmen and the eastward-moving European trekboer began in the region of the Fish River during the rule of the Dutch East India Company. Cattle and land were the main ingredients of the frontier conflict. From the point of view of the white settler, the growing cattle trade meant an increased need for pasture, but although the motive for expansion was economic, frontiersmen had come to regard large lands as their birthright. The semi-nomadic pastoral economy of the Nguni also required abundance of land, which was vested in the tribe.

- Description: Two possible variables of the McKenzie/Stoughton blanching assay, namely amount applied to the test site and occlusion time have been investigated. Subsequently, two topical steroid preparations, Synalar cream (0,025% fluocinolone acetonide) and Betnovate cream (0,1% betamethasone 17- valerate) were extemporaneously diluted with five and six placebo bases respectively. Taking cognizance of the two possible variables, these diluted preparations were assessed in vivo using a modified version of the McKenzie/Stoughton blanching assay for blanching activity over a 14 month period. It was found that the base E45, which is slightly alkali, had the greatest effect on both preparations. In the case of betamethasone 17-valerate this base caused the conversion to the less active isomer, betamethasone 21-valerate whereas at the end of the 14 month test period it was found that the Synalar/E45 dilution contained no fluocinolone acetonide. Quantitative analysis of all the diluted preparations by high performance liquid chromatography using a reverse-phase system was performed. The data obtained from the systematic studies of the effects of varying concentrations and occlusion times were presented at the Eleventh National Congress of the South African Pharmacological Society

Gold mineralization in archaean cherts and iron-formations a review of the economic geology

- Description: The distribution of gold in igneous rocks and minerals is described and discussed. Not all the gold in igneous rocks is contained within early formed crystal lattices. Evidence that gold can be associated with late stage crystallizing phases is described. It is concluded that some of the gold in hydrothermal and volcanogenic deposits may have come from a primary magmatic source rather than having been leached from solid country rock. Gold is probably transported as chloride complexes at temperatures greater than about 300°C. At lower temperatures it is probably transported with other metals as sulphide and thio-sulphide complexes. The precipitation of gold from the transporting medium is brought about by changes in the physico-chemical conditions within that medium. Decrease in pressure is probably not a major cause of precipitation in volcanogenic environments. The geology of volcanogenic iron-formations is described and discussed, relative to the development of greenstone belts. Oxide facies iron-formations were formed in shallow oxidizing environments. They are associated with volcanogenic and clastic sediments. Sulphide facies iron-formations were precipitated in the deeper parts of geosynclinal structures. They are associated with mafic and ultramafic rocks similar to modern oceanic volcanic assemblages. Carbonate facies iron-formations were deposited in the regions between oxide facies and sulphide facies. Other banded iron-formations are found associated with base metal massive sulphide deposits related to arctype volcanic centres. These deposits are found in the regions where carbonate facies iron-formations were formed. Exploration for and exploitation of gold deposits in Archaean iron-formations are discussed. Geochemical exploration programmes are aided by the association of gold with trace amounts of base metals. Geophysical exploration methods that can be employed include magnetometer, I.P. and E.M. surveys. The metallurgical treatment of the ores should include "roasting" because a large proportion of the gold occurs as submicroscopic grains within sulphide mineral crystals.

Graaff-Reinet and the Great Depression (1929-1933)

- Description: The Depression of 1929-1933 was a world-wide phenomenon, in which "no aspect of the economy, no part of the world, escaped devastation". ¹ Accordingly the study of a medium sized rural town in South Africa during the period of the Depression, should show effects and reactions that were, in general, indicative of worldwide trends. In choosing Graaff- Reinet, I felt that being a close-knit community , with its urban and rural populations closely associated with each other, and the white, coloured and black sections of the population interdependent, it adequately represented a microcosm of South Africa as a whole. Then, too, Graaff- Reinet was ideally suited to illustrate the reality, that in South Africa during the Depression " the farmers were the most heavily hit of all". ² The single most significant product of the Graaff- Reinet district was wool, which at the time of the Depression was South Africa's second most important export, and consequently the well-being of the whole district depended largely on the market performance of this product . During the Depression the price of wool dropped drastically and the Graaff-Reinet farmers suffered in consequence . Graaff-Reinet also went, almost according to a blueprint, through the general phases of the Depression. The privations of the farming community led to the financial embarrassment of the local financial institutions causing their collapse , which in its turn led to the widespread hardship of everyone in the town. But these events all had a particular Graaff-Reinet quality, and the twists to the general outline are rooted deep in the local character of the district . Historically Graaff-Reinet is extremely interesting. It is the fourth oldest town in South Africa, being established in 1786, and in studying Graaf-Reinet one cannot but become conscious of the immense tradition and the awareness of history , which all its people have. The study itself starts with a general outline of the Worldwide Depre ssion, its causes and results, then moves on to the Depression in South Africa . The study of Graaff-Reinet in the Depression is divided into three basic sections, the Farmers, the Townspeople, and the Politics of Graaff-Reinet during the Depression. All three contain their own sub-divisions dealing with different aspects. In the Graaff-Reinet sections are included references to national events, tying them to, and explaining the course of, local happenings. In short the study becomes the story of how the Depression effected the people of Graaff-Reinet, how they suffered during this period and how they reacted to it. A final concluding section deals with their general recovery from the Depression. ¹ Heaton, H. : Kruger, D. W.

- Description: Stanislaw Lesniewski (1886-1939) was professor of Philosophy of Mathematics at the University of Warsaw from 1919 until his death. He played a leading role in the Warsaw school of logic and had a lasting influence on many of its members. Lesniewski constructed his first description of mereology in colloquial language and in the absence of a secure logical foundation. In order to effectively distinguish between the collective and distributive notions of class, further description of the distributive notion was necessary. He therefore formalized the distributive concepts in his theory of ontology. Henceforth "ontology" will be used specifically to refer to this theory of Lesniewski. Finally, the construction of protothetic (a system of propositional logic) provided a sound logical foundation of Lesniewski's ontology and mereology. Protothetic, together with his prescribed rules of procedure and his grammar of semantic categories, also facilitated the formalization of his systems in a logically rigorous manner. All of the researchers acknowledge that one of Lesniewski's most fundamental achievements was the development of his deductive systems (protothetic, ontology and mereology).
