- Description: The Ciskei was gradually ‘consolidated’ by a process of geo-political gerrymandering that included the incorporation of black dormitory townships dependent on ‘white’ cities outside the homeland for survival. By 1973, the Ciskei homeland’s de facto population was estimated at 602 000.4 Since then, the overcrowded rural population has been forced to absorb thousands of refugees removed from South Africa’s ‘white’ areas — including several ‘black spots’ now outside the boundaries of the homeland — and migrants from two districts (Herschel and Glen Grey) formerly in the Ciskei which were ceded by the South African government to Transkei. Any attempt at measuring the extent to which communication affects the political credibility of the present Ciskei homeland in the eyes of its inhabitants must be weighed against these historical realities. This monograph is divided into three parts: 1. An outline of the political system in the Ciskei. 2. The role of the mass media in determining attitudes towards homeland news. 3. Some observations on the status accorded oral channels of communication in the transmission and validation of political news in selected rural and urban areas of the Ciskei. In obtaining data for this study, five surveys were conducted in two rural villages, the biggest urban area in the Ciskei and the Ciskei Legislative Assembly. The villages of Gobozana (or Xengxe) and Nyaniso formed the basis of the rural surveys conducted in April — June 1976. Fifty heads of homesteads in each village, in a universe of about 500 homesteads, were selected at random. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: From Introduction: Thus for the black South African, the act of creative writing is inescapably a form of political action, and unless he turns his back on the reality which confronts him and retreats into a private imaginary world, it is also a form of social action, Yet Ezekiel Mphahlele has rightly cautioned that "creating an imaginary world" can never be an effective substitute for social act ion . Composing fictions about social and political problems is an indubitably oblique way of seeking a solution to them, and even the tendentious recreation of reality is only a metaphor for its actual transformation. Protest writing in South Africa is paradoxically a form of social action which is also only a parasitical imitation of social action, and therefore its avoidance . The freedom of literary creation described above is ambiguously not only a freedom to express reality, but also a freedom from the constraints of reality. And this suggests why the outlaw was such an important symbol to an earlier generation of rather more self-conscious writers.

Satan and Lucifer: a comparison of their metamorphoses from Angel to Devil in Milton's Paradise lost and Vondel's Lucifer and Adam in Ballingschap

- Description: The aim of this thesis is to compare the poetic delineation of the character of Satan in Paradise Lost with that of Lucifer in Lucifer and Adam in Ballingschap, and to consider the influence of the genre in each case , not in order to prove similarities or differences , but rather to allow the characters to illuminate each other. Both Satan and Lucifer develop progressively from angel to devil in the course of the poem or play. However, this process is more than just a physical metamorphosis, or even a moral degeneration. It is in each case a process of identity change, intensely and consciously experienced by the character. The fall is a movement from God to Self. The unfallen creature's integrity consists in his submergence in the Being and Will of God; for the fallen creature integrity means a separate, independent self-hood. In rebelling against their role and duty as Archangel, Satan and Lucifer rebel against submergence in the Being of God and thus against their very nature and the order of things. Consequently they experience personal and psychological disintegration. From this condition of imbalance and uncertainty they both develop to a new state of personal reintegration and unequivocal identity, now as Arch-fiend. In neither case is the process instant or entirely concurrent with the physical fall into Hell. Rather, it is protracted, hence the division of this thesis into sections that focus on the different stages in the development: Archangel, Arch-rebel and Arch- fiend (introduction, p. ii-iii).

Sedimentology of the Katberg sandstone in the Eastern Cape Province

- Description: The Katberg Sandstone is an arenaceous formation occuring stratigraphically three querters of the way up in the Beaufort Group in the south-eastern part of the main Karoo basin. A sedimentological study was carried out on the Katberg Sandstone and adjacent formations, in a 2 000 km² area south of Queenstown. Stratigraphic sections were measured and lithofacies based on the style of Miall (1977) were established for the Katberg Sandstone, Balfour and Burgersdorp Formations. Stratigraphic relationships show that the Burgersdorp Formation in the study area, is the lateral (distal) equivalent of the Katberg Sandstone. The changeover from sandstone to predominantly shale lithology occurs roughly east-west between Cathcart and Whittlesea. Stream hydraulic theory is discussed and the sedimentary structures of the various lithofacies are explained in terms of this theory. An analysis was done of thirty-four palaeochannels, and their various ancient flow characteristics were derived via multiple regression equations and a FORTRAN computer program. A statistical analysis of bedform structures, showed that flat-bedding of the upper flow regime is the dominant sedimentary structure of the Katberg Sandstone. Trough cross-bedding originating in aqueous dunes and planar cross-bedding of transverse bars, are fairly well represented while ripples are virtually absent. The opposite applies to the Balfour Formation where lower flow regime structures, viz., ripple cross-lamination and trough cross-bedding predominate. There is an even spread of (upper) flat-bedding, trough cross-bedding and ripple cross-lamination in the Burgersdorp Formation. Detailed measurement of typical short sequences from sections of the three formations, and transition matrix analyses, showed the facies assemblages to be of three stream types: (i) Katberg type: similar to Platte type of Miall (1977). Sediments were deposited by swiftly flowing, low sinuosity, braided, ephemeral streams with a predominantly sand bedload. Each flow started with preconsolidated silt and mud (flakes), and movement of exogenetic pebble lags. Channel avulsion and deposition of mud drapes in higher topographic levels of the stream were common phenomena. (ii) Balfour type: characterised by lateral accretion point bar type sequences of high sinuosity streams, and vertical accretion floodplain deposits. Lower flow regime dune and ripple bedform structures overlying (upper) flat-beds indicate a loss of stream power with channel migration. (iii) Burgersdorp type: similar to Katberg type for sandstone units, also crevasse-splays onto thick subaerially exposed floodplain aggradation reddish shales. Conventional microscopy and SEM studies showed tremendous diagenetic effects mostly in the form of secondary quartz growth in the sandstones of the three formations. Electron microprobe analyses were done on titanomagnetite grains from heavy mineral layers of the Katberg Sandstone, so that thermometric predictions could be made on provenance rocks. Palaeocurrents of the Katberg Sandstone are mostly Rank 4 and 5 types (Miall, 1974), i.e., they were generated within bars with not much change in stream orientation. Burgersdorp and Balfour formation palaeocurrents are Rank 1 - 3 types. In the case of the former this is owing to directional changes in channels as a result of frequent crevasse-splays, and in the case of the latter owing to differences in orientation between entire tracts of highly sinuous palaeostreams. Palaeocurrent directions in the Katberg Sandstone indicate a southeasterly provenance which accords with the findings of other Beaufort Group workers. Bed relief index calculations (Smith, 1970), made on Katberg rocks, considered together with the abundance of planar cross-bedding (of transverse bars) and apparent absence of longitudinal bars, testify to the deposition of the Katberg Sandstone in the distal parts of the braided stream environment. The Beaufort sediments of the study area have the sedimentological characteristics of a molasse sequence, but a different implied tectonogenesis. During Balfour sedimentation the equilibrium base was being raised very slowly at the source and complete fluvial sequences were deposited under a humid temperate climate, on a slowly subsiding plain. During Katberg/Burgersdorp times, source area tectonism was pronounced but interrupted and incomplete sequences were deposited under an arid climate. Provenance rocks for the formations studied included biotite mesoperthitic granite, granulite, charnockite, granite porphyry, granophyre, metaquartzite, greenschist and possibly diorite, epidosit e and alkaline volcanic rocks. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Pelagic marine fish eggs were collected over a period of 28 months from inshore waters of the Cape of Good Hope.

- Description: A study of the story of Cupid and Psyche within the context of the Metamorphoses as a whole reveals a recurrent pattern of themes, motifs, and images, which indicates that the story symbolises the experiences of Lucius. The Judaeo-Christian Greek meaning of psyche, oneself, implies that Psyche is a symbol of Lucius. This is borne out by the similarity of their experiences, and by the fact that they both have the same character traits of simplicitas and curiositas. Cupid's warnings to Psyche concerning the control which Fortuna has over her life further establish the connection between Psyche and Lucius, whose life is controlled by blind Fate. Military imagery, and images of light and dark, which occur in connection with Cupid and Psyche, also describe the experiences of Lucius. Venus symbolises Isis, as is indicated by Isis' identification of herself as Venus, in addition to many other deities, at the end of the Metamorphoses. Once again imagery, this time of the sea, makes this relationship clear, while military imagery implies a parallel between the relationship of Psyche and Cupid, and that of Lucius and Fotis. Jupiter intervenes in Psyche's misfortunes, just as Isis saves Lucius from his hardships. Juno and Ceres are also identified with Isis at the end of the Metamorphoses, thus linking the story of Cupid and Psyche with the life of Lucius.

- Description: In the last two decades much has been published on the behaviour of certain elements in the magmatic , hydrothermal, sedimentary and weathering environments , but the information is scattered throughout the literature . This situation prompted the present study on the elements Ni, Co, Cu, Pb , Zn , Au, Ag , Mo , Sn, W and U. The behaviour of the elements Ni, Cu, Pb , ZN, Au, Sn , W and U has been studied experimentally in some depth. Ag has been moderately studied, but there is very little information about Co and Mo. Studies on the complexes formed by the elements within the hydrothermal and aqueous environment are often inconclusive and controversial , but conclusions are drawn as to the more likely complexes formed . A genetic classification of ore deposits is used as a framework for the discussion . The source of the elements is regarded as being the mantle, and therefore discussion on other possible sources is beyond the scope of this dissertation. The crystal chemistry and geochemistry of the elements are presented and the essay concludes with a discussion on the elements within their depositional environments

The contribution of Spartina Maratima (Curtis) Fernald to the primary production of the Swartkops estuary

- Description: The primary production of Spartina maritima, the dominant macrophyte of the intertidal salt marshes of the Swartkops estuary, was determined for inclusion into the proposed ecosystem model. Several methods for measuring net production devised for North temperate Spartina species were used, as no single method was considered reliable for the local species. In addition, a new method was devised to take into account the aseasonal growth behaviour of S. maritima . Most energy for growth appears to be directed into leaf production, rather than shoot growth. Live net production values were 523-680 g m⁻² yr ⁻¹, which are generally lower than estimates of N. American Spartina species. Total Live production of S. maritima for the whole Swartkops estuary was 495,6 x I0³kg yr ⁻¹, which is an estimation of potential food resources. Formation of S. maritima detritus by decomposition was significantly related to air and water temperatures. Thus detritus production showed a wide seasonal variation about a mean of 374 g m⁻² yr⁻¹. The total S. maritima detritus production of 307,5 x I0³kg for the whole Swartkops estuary was determined as an estimate of available food resources. Export of detrital material from Spartina marshes to estuarine waters was negligible. Even during a maximal Equinoctial tide, only 6,26 dry g m⁻² detritus was exported from the creek catchment area of Spartina stands. This study has shown that concepts evolved for North temperate estuaries should be carefully considered before being applied to local situations, particularly in view of the relatively low, aseasonal production of S. maritima and the negligible contribution of its detritus to estuarine waters. Furthermore, it is essential that utilisation of primary production by secondary producers be determined before the function of the estuarine ecosystem may be understood

- Description: This study embraces two aspects of closed system culture: (a) a comparative study of four different biological filtration treatments, and (b) a quantitative determination of the nitrogen flow in a particular biological filtration system. Twenty 0,5 g juvenile Penaeus indicus Milne Edwards were cultured for approximately two months in four different kinds of sea water recirculatory systems with bacterial filtration, algal filtration, algar plus bacterial filtration and water exchange (25% every 3 days). Growth was comparable to that found in the literature for P. indicus. Nitrification occurred in all systems irrespective of the type of biological filtration employed. Ammonia, nitrite and nitrate levels were reduced by the algae, but nitrate accumulated to approximately 30 mg NO¯³ -Nℓ¯¹ in those systems without algae. Depletion of trace elements (Cu, Fe, Zn, Hn and Co) by the algae did not occur due to trace metal replenishment from the addition of food. No marked changes occurred in the concentrations of the major cations (Ca⁺⁺, Mg⁺⁺, Na⁺ and K⁺), but a small increase in Ca⁺⁺ levels was detectable in those systems with oyster shell chips in the filtration medium. Only minor changes occurred in oxygen or pH values in the various systems tested. Inorganic carbon levels showed major increases in the algal filtration systems, while a slight drop occurred in the bacterial filtration systems. The increase in the algal filtration systems was thought to be due to the formation of carbonates and bicarbonates by the reaction of respiratory CO₂ with unionized ammonia and water. Suggestions are made as to how closed systems can be improved upon. By determining the rate of excretion of P.indicus as related to size and temperature, its faecal production, and the nitrogen content of P.indicus, its food and faeces, the nitrogen flow within a system could be calculated. P.indicus was found to have an assimilation efficiency of 88,93% and a food conversion ratio of 3,49:1. Of the total dietary nitrogen input into the system, P.indicus ingested 69,02% - 19,80% of which was used for growth, 41,58% excreted and 7,64% lost as faeces. The remaining 30,98% of the total nitrogen input can be regarded as excess food nitrogen. The total nitrogen loading on the biological filtration system was found to be 80,20% of the total input of dietary nitrogen. The ability of various types of filamentous algae to remove these nitrogen compounds was determined. Suggestions are made as to the application of this information on nitrogen flow to the culture of P.indicus
