With this in mind reference has been made to individual men and their particular importance and also to the decislons of the Church Assembly as they affected Mission. In part, the thesis is fuller for the earlier years, for the writer holds that these were the most formative as they established the pattern.

- Description: The plant communities of the Andries Vosloo Kudu Reserve (6493 ha.; Acocks's Valley Bushveld) are classified using the Braun-Blanquet phytosociological technique. A checklist of the flowering plants is presented. The flora of the reserve displays an affinity to five phytochoria (Capensis, Karoo-Namib, Sudano-Zambezian, Afro-montane and Indian Ocean Coastal Belt 1, of which the Karoo-Namib and Indian Ocean Coastal Belt are the most extensive. The flora of the Valley Bushveld is regarded as adequately conserved, but a recommendation is made to consolidate the study area with adjacent farms. A small herbarium, containing specimens of all species listed in the checklist, has been established. The climate of the study area is classified according to the Koppen classification as Cfa. Simultaneous air temperature recording at four separate localities demonstrated that differences exist between local ities of marginally different altitude, aspect and slope. The phenology of 51 plant species, recorded at monthly intervals over a continuous period of 478 days, is presented. These species are classified according to their response to air temperature and rainfall for the initiation of new growth, flowering and fruiting. Species exhibited a spectrum of responses ranging from endogenous to exogenous control over phenological events. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: This working paper covers a survey conducted between 16 and 30 January 1980 of 3 171 black Sub A and Sub B pupils 8 years old or younger, at schools in both the rural and urban areas of the Albany Magisterial District, Eastern Cape. The survey, under the auspices of the Institute of Social and Economic Research (ISER), Rhodes University, was carried out as a result of a request from Dr J. D. Krynauw, Regional Director of Health Services in the Eastern Cape, to assess levels of nutrition of black children. Newspaper reports (see Appendix 1) of low levels of nutrition and high infant mortality rates among young black children in the Eastern Cape appeared to suggest a chronic nutritional situation, a situation not perceived as such by the Department of Health. A comprehensive pilot study was instituted on written request from Dr Krynauw in late October 1979. A report of the pilot study findings was presented in May 1980 to the Department of Health (Fincham, 1980). The present paper elaborates on that report and also includes analyses of data not presented before. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

An investigation into the influence of the physical distribution concept on the performance of certain South African manufacturers of consumer products

- Language: English
- Type: Thesis , Doctoral , PhD

- Description: The "Physical Distribution Concept" is being increasingly recognised as a vitally important business philosophy for those firms for which efficient physical distribution is critical to marketing success. Manufacturers of products which are perishable, easily substitutable; and/or quickly obsolescent are some which fall into this category. In a competitive business environment, factors such as the " availability" of the product, and not simply its price or quality, begin to exert a significant influence on the purchasing decision. The "Physical Distribution Concept" comprises three elements, namely, consumer orientation; organizational integration and profit orientation. "Physical Distribution Orientation" refers to the predisposition of the firm and its employees to these three elements. For the Physical Distribution Concept to serve as an effective guide to management action, a physical distribution orientation on the part of all those concerned with marketing and physical distribution-related activities in a firm, is a pre-requisite. The chief executive, in particular, should adhere to this business philosophy, regardless of the functional route he followed to his position. In his leadership role, theory holds that he exerts considerable influence on his subordinates, and consequently on his firm's way of doing business. This thesis is concerned with an analysis of the Physical Distribution Concept. It focuses on the chief executives of firms manufacturing consumer convenience goods, as well as consumer shopping goods. As such, it is primarily concerned with determining the extent to which the chief executives are physical distribution oriented and whether there is a statistically significant relationship between their extent of physical distribution orientation and their companies' performance. The thesis is also concerned with the extent to which any pattern of organizational arr angements for physical distribution exists.

- Description: From preface: The original purpose of this thesis was to make a comparative study of all the English literature which had been prescribed from 1945 to 1980 for study by all high school pupils in the Republic of South Africa, Zimbabwe and the ex-High Commission Territories. This proved to be a formidable task. However, most of the material collected, including all the individual poems prescribed, was recorded in table form. This proved too bulky a system for comparative purposes and the field was narrowed to include only that English literature which had been prescribed for candidates writing Matriculation or Senior Certificate examinations on the higher grade as part of the English Language syllabus. From time to time, however, reference will be made in this thesis to prescriptions for the lower grades and for the lower standards.

Aspects of the biology of Caffrogobius Caffer (Günter) (Pisces : Teleostei : Gobiidae) in the Eastern Cape

- Description: Several strategies used by the gobiid fish Caffrogobius caffer enabling it to colonise the harsh intertidal environment in the eastern Cape were studied. Q. caffer is opportunistic in its use of available food resources and feeds throughout the day with a slight tendency towards crepuscular peaks of feeding activity. The system of space utilisation used by C. caffer is so organised that all individuals of the population have access to patchily distributed food resources. Current velocities occurring over high tide limit the movements of Qo caffer and interpool movements occur only during the initial stages of a rising tide and in the final stages of an ebbing tide when the current velocities are below the tolerance limit of Q. caffer. The epifauna associated with the alga Ulva rigida, which forms an important constituent of the diet of the intermediate size classes of Q. caffer, was examined and it appears that this epifauna is an important source of food to Q. caffer. This report presents the results of the first detailed study of the biology of an intertidal fish in southern Africa.

- Description: From preface: This study of the British settlers of 1820 in South Africa uses one party of emigrants as a unit of historical research. In unfolding their story, it attempts to discover how far the standard assumptions about the 1820 settlement are borne out by the historical facts. No systematic set of hypotheses for investigation was established in advance; instead, the structure of the thesis has been determined by the course of the narrative, and the main issues have emerged spontaneously as it has progressed. Although the chronology has been maintained as far as possible, the narrative itself does not follow an entirely straightforward course. The emigrant party of eighty-four men and their families under the leadership of John Bailie which is the subject of the study was officially subdivided five weeks after landing at Algoa Bay, and the dispersal of its members to the established towns of the colony began even sooner. At the end of the three-year period laid down as a residential qualification by Government, less than a third remained to claim land on the party's location in Albany.

Betnovate and Celestoderm-V lotions produced almost identical blanching profiles. Diprosone lotion displayed a statistically significant superior blanching acitivity over both Betnovate and Celestoderm-V lotions over the whole timespan of the trial.

That most Industrial Councils are presently unrepresentative of the majority of workers and therefore undemocratic. That the Constitution and structure of most Industrial Councils reflects this un-representativeness and authoritarian base and it would be difficult for any small and democratic union to have an effect on Industrial Councils as they presently exist. That some Industrial Councils., because they are dominated by employers, misdirect workers' money collected either in the form of a levy or in benefit funds. That some Industrial Councils have blocked speedy solution to industrial problems by placing cumbersome procedures and bureaucratic structures in the way of direct negotiation between employers and workers.

- Description: From Introduction: This thesis then is a detailed study of Lessing's novels in an attempt to show her development as a writer. Her short stories are handled briefly in connection with her novels. For, although the short stories are among her finest work, focus on the novels is sufficient to show her growth as a writer. Hers is the small individual struggle to overcome the limitations of both her content and her form. To overcome the limitations of her content means expanding her own consciousness and re-forming life itself. Only when she is free and the world is free can she overcome the limitations of her content. Then, of course, she need no longer and can no longer write. The task seems as impossible as that of the dung beetles, but she nevertheless continues. Like the sacred beetles with "the sun between their feet" she carries on rolling the muck of the world into symbols of the truth.

- Description: Stratiform and stratabound ore deposits commonly show a direct relationship with rifts. This association is studied by developing a geodynamic model of mantle processes and crustal responses. The geodynamics of the earth can be modelled by the process of mantle advection, which involves the episodic generation and segregation of low density mantle diapirs and their rise and subsequent interaction with the crust. The theory of mantle advection explains the genetic association between rifting, magmatism, basin development and subsequent orogeny and metamorphism. Global evolution has passed through a number of major stages of non-uniformitarian development in which each cycle was characterized by fairly uniform behaviour terminated by intense geodynamic upheaval. The relationship between geological evolution and mantle advection is examined by reviewing the major characteristics of each of the cycles, which correspond to the Archean, Early Proterozoic, Mid Proterozoic, Late Proterozoic-Palaeo2oic, and Mesozoic - Cainozoic eras. Although mentle advection has controlled crustal processes throughout time, the decrease in the thermal energy of the earth has caused >the major evolutionary changes in response to thickening and a greater rigidity of the sialic crust. Rifts are penetrative taphrogenic faults in the earths crust which act as major conduits for the transfer of magmas, from the mantle and lower crustal levels, to the upper crust and the surface. Rifts are also permeable zones for the migration of metalliferous brines, generated by magmatic differentiation. These metalliferous brines would either be exhaled at surface to form stratiform volcanogenic and volcanosedimentary ore deposits , or would interact with preferential host horizons to form stratabound ore deposits . The associat ion between rifting and stratiform and stratabound ore deposits is illustrated by examining :he tectonic setting, and st ratigraphic relationships of typical ore deposit types .

Geological factors affecting the grade and tonnage of sandstone uranium deposits

- Description: The largest known reserves of uranium are found in sandstone deposits, in the form of roll-front, peneconcordant and stacked types. Drilling on spacings of between 50 m and 5 m centres is the current method of attempting to delineate such ore bodies but because of the apparent random distribution of the mineralization there is a large degree of uncertainty in these predictions. Even on drilling grids of 3,5 m centres the uncertainty in predicting the distribution of stringer ore in roll front mineralization is still 100 per cent. (Sandefur & Grant 1980). Because of escalating costs it is becoming increasingly less economically feasible to delineate bodies of this nature in this manner and much more reliance will have to be placed on the geologist's interpretation of ore distribution when calculating ore reserves. The grade and tonnage of a sandstone uranium deposit can only be calculated with some degree of confidence if the processes forming the ore body are fully understood. The aim of this review is to examine the factors governing the formation and geometry of a sandstone body, the mobility and fixation of uranium and to establish criteria which will enable a more confident prediction to be made of the distribution of sand bodies and the distribution of the mineralization within them

- Description: The occurrence of a major metalliferous province in Zambia and Zaire is a reflection of geological processes operating in a specific environment during a particular period. The size of orebodies, their grade, mineralogy, beneficiation characteristics and therefore the amount of metal produced are all ultimately functions of the geology of the ores. This study is primarily concerned with the effect geology has on tonnage-grade relationships of ore in situ on the Zambian Copperbelt. Five major topics related to ore tonnage and grade are reviewed here: -behaviour of copper and cobalt in surficial environments. -geological setting and gross lithostratigraphic relationships of mineralization. -characteristics of known orebodies. -geological factors affecting mining and beneficiation of ore. -orebody limits and estimation of tonnage and grade. In addition, the historical background to the problems discussed here is briefly described, and some general aspects of the evaluation, mining and beneficiation of Copperbelt ores are considered in relation to metal production.

Geological factors that influence the evaluation and exploitation of Canadian copper-zinc massive sulphide-, and Japanese polymetallic (kuroko) deposits

- Description: Volcanogenic massive sulphide deposits are important sources of base metals throughout the world. The Canadian Cu-Zn-(Au, Ag) deposits of Archaean age occur in greenstone terrains within the Canadian Shield. These deposits are closely associated with volcanic vents developed along zones of rifting within mobile belts. The vents are manifested by coarse felsic pyroclastics and/or rhyolitic domes. The Japanese Pb-Zn-Cu-Ba(Ag) deposits, generally known as Kuroko deposits, are of Miocene age, and although also associated with volcanic vents, are developed above zones of subduction. Mineralization in volcanogenic deposits is a result of submarine exhalation of metalliferous hydrothermal solutions derived from fractionation of predominantly calc-alkaline magmas. The deposits are characterized by certain geological features that result from the interaction of specific physical and chemical conditions during deposition. Primary features include massive and stringer sulphide bodies, alteration zones, mineralogical and metal zoning, and certain depositional textures and structures. These features are commonly modified by subsequent metamorphism and deformation which impart secondary ore textures and affect metal distribution and shape. The disparity in age between Canadian and Japanese deposits allows the entire spectrum of geological features to be studied; from the completely unaltered to the high deformed and recrystallized. The characteristic geological features are the prime factors which control the metal distribution and concentration, and the size and shape of the deposits, thereby influencing the viability of the respective ore bodies. A knowledge of these factors and the physico-chemical parameters which control them are thus fundamental in the "understanding" of these deposits. They ultimately control the geological interpretations and predictions made during ore body delineation, ore reserve estimation, mining and ore beneficiation.
