A study of the tragedy of Coriolanus by William Shakespeare

- Description: It would be difficult to prove conclusively that Shakespeare was not invited or requested to write a play based on the popular story of Coriolanus. J.M. Robertson concretises this possibility with an intriguing thesis that the play was in fact rewritten from an original by Chapman. The story, he argues, would have had a far greater appeal to Chapman with his consuming interest in the heroic age of Classical antiquity, than to Shakespeare. Further, it is likely, he says, that Chapman was familiar with Alexandre Hardy 's Coriolan which, it is generally accepted, Shakespeare was not, hence the startling similarities in some of the two plays' deviations from their common source. This is hardly a more satisfactory explanation than the kind of airy alternative that disposes of the mystery by saying the source material is such that it would invite any dramatist to make similar changes.

- Description: From Preface: In 1966, the Karroo Development Association approached Rhodes University to undertake a socio-economic survey of their region. This survey was to form the basis for development planning in view of the expected benefit to the region of the Orange River Project. Similar requests were also received from the Midlands Planning Association and the South Eastern Areas Development Association. When Rhodes University consulted the Department of Planning, which strongly supported the principle of a regional survey, it was decided that, although Port Elizabeth and its hinterland comprised a logical economic unit, the area should be sub-divided. The University of Port Elizabeth was entrusted with the responsibility for an analysis of the metropolitan area, while the Institute of Social and Economic Research of Rhodes University was commissioned to undertake a socio-economic survey of the inland areas. This thesis on the transport infrastructure of the Cape Midlands and Karroo Regions represents one aspect of the survey.

An enquiry into some present-day attitudes in art education and their relationship to the current alienation of artist from society

- Description: From Introduction: "We can't teach these kids anything, man, they are so pure and unspoiled. Anything we show them or any discipline we impose upon them will only corrupt their purity. It's best if they just stay home and do their own thing”. "If your instructor says he knows what art is, watch out.” These two statements, the first by an instructor at a prominent New York art school, the second by one of America's respected critics, are the sort of talk one might expect to hear at any gathering of the avent-garde . To hear them said in and about the art school puts things in a different light. They are indicative -of the sort of thing that is preached and practised by a sufficient proportion of the art- educational force in the Western world to constitute a crisis unparalleled in the entire history of art education. Unopposed, such views must rapidly spell death for the institution. They must also, if they reached the proportions their authors appear to hope for, ensure a universal visual illiteracy unequalled in any other age. Of course statements like this, archly delivered by the very people who would suffer the most immediate loss at their implementation, are not at all true reflections of the whole state of art education in our time, or those people would simply not be in a position to make them. There are a great many people in the profession who would wholeheartedly reject such statements, and this faction is by no means confined to the older members.

- Description: The doll placement technique is a projective instrument which yields objective measures from which inferences may be drawn. Subjects place pairs of dolls to represent social encounters described to them by the experimenter. When the dolls have been placed, the distance between them and the angles at which they stand can serve as a source of information either about the personality of the placer or about the way in which he perceives the relationship between the interactors represented. Most experimental work employing figure placements has used flat felt figures which subjects have mounted on a flannel graph. This method limits an investigator to one dependent variable, the inter-figure distance. However if three dimensional dolls are placed three dependent measures can be derived from a placement, one of distance and two of orientation. It has been demonstrated that a reliable correlation exists between the spatial relations between figures placed by a person and the spatial relationships between real interactors. The theoretical analysis of the determinants of interpersonal distance and orientation in social encounters which has been worked out by students of non-verbal behaviour is therefore able to serve as a basis for the interpretation of the spatial characteristics of doll placements. Previous work with the doll placement technique has concentrated on the distance between dolls. The present study explored the determinants of figure orientations. Firstly an analysis was made of the types of orientation pattern that can occur when two persons are involved in a social encounter. Secondly, an experiment was performed which was designed to explore whether asymmetry in an orientation pattern might act as a cue to determine how individual figures in a pair were perceived. Thirdly, two doll placement studies were performed which were designed to investigate the conditions giving rise to asymmetrical orientation patterns and the determinants of direct and indirect orientations. The confidence or anxiety attributed to an interactor represented by a figure proved to be a major determinant of its spatial position. The results of the study indicate that the use of the angle measures in the analysis of doll placements considerably enhances the value of the technique. It is argued that the doll placement method could be profitably employed both as a clinical instrument and as a research tool for cross-cultural psychology.

Aspects of the biology of aestivation in Bulinus (Physopsis) africanus (Krauss) (Gastropoda, Pulmonata)

- Description: Aestivation, a period of dormancy during hot, dry conditions, is known to occur in both the Prosobranchia and the Pulmonata among freshwater Gastropoda. While there have been numerous accounts, mainly by field ecologists concerned with bilharziasis control, of the survival value of aestivation in the Gastropoda, little is known of its underlying physiological mechanisms. Results of investigations into the physiological basis of aestivation in the freshwater Prosobranchia, confined to the family Ampulariidae, have been conflicting, fundamental differences having been shown to exist between different species of the genus Pila . Only a single comprehensive study, that by von Brand and his coworkers on the planorbid snail Australorbis glabratus*, forms the basis of our knowledge of the aestivation process in the aquatic Pulmonata. In view of the conflicting results obtained in investigations on freshwater Prosobranchia, the general applicability of the findings for Australorbis glabratus to other freshwater Pulmonata was open to question. The present investigation on the planorbid snail Bulinus (Physopsis) afriaanus, a species known to be a successful aestivator, was prompted by the obvious need for a further comprehensive study on an aquatic pulmonate species . The results presented here show that aestivation in this species is a definite physiological state, characterised by a depression of the metabolic rate, which not only aids in husbanding the snails I metabolic resources. during the enforced starvation which must necessarily accompany aestivation, but also constitutes a form of resistance adaptation to the transient high temperatures which aestivating snails are bound to encounter. Loss of body water is shown to be important in initiating aestivation, but it is also the factor most likely to prove lethal during the course of aestivation. The results confirm and extend the earlier findings for Australorbis glabratus. The results are discussed in the context of our present knowledge of aestivation in other Gastropoda, both aquatic and terrestrial, and also in relation to other forms of resistance adaptation. As expected, the investigation raises more questions than it answers, thus directions for further research, arising out of the present findings, are suggested.

The biological activities of B. decoloratus during its parasitic cycle are examined with special reference to the course of feeding of all stages, and to the influence of the pharate nymph and adult conditions in accelerating the completion of the cycle. 3. The pattern of dropping of replete females is considered in relation to their weight and their time of drop-off. 4. The adult male population structure is described. Two distinct weight groups are reported and the taxonomic significance of these is discussed. 5. The preoviposition period duration of B .decoloratus was studied under laboratory conditions and found to be temperature dependent and humidity independent. Female size, as implied by their engorged weights, influenced the duration of the oviposition period: ticks weighing less than 20 mg possessed longer preoviposition periods. 6. The preoviposition period of B.decoloratus females under fluctuating macroclimatic conditions was studied and found to be long in duration. The implications of this are discussed in relation to laboratory findings and the summer build-up of this species in nature. 7. The duration of the oviposition period of B. decoloratus and the number of eggs produced during this period were studied under laboratory and field conditions. Both these parameters were found to be temperature dependent and uninfluenced by humidity. The significance of a temperature dependent oviposition period is discussed. 8. The minimum amount of 'blood' required by female ticks for oviposition of eggs was found to be approximately 16 mg. under laboratory conditions. 9. The oviposition behaviour of B. decoloratus females has been described and the water relations of ovipositing and non-ovipositing females were examined and discussed . 10. The effects of handling female ticks during their oviposition period was studied and females which were handled were found to produce significantly fewer eggs. The significance of this is discussed. 11. During preliminary experiments on the incubation period of B. decoloratus it was found that the viability of eggs laid during the first half of the oviposlting period was greater than for eggs laid in the second half of the period. The critical temperature of the 'wax' coating of eggs was found to be 42⁰C while the critical humidity was approximately 70% R.H. (7,53 mmHg) at 26⁰C. The implications of these findings are discussed. 12. The development of eggs, traced throughout the incubation period by monitoring the build-up of guanine spectrophotometrically, was studied under different humidity conditions . Successful development was found to be dependent on the water content of the eggs at the time of laying. As eggs were also found to be unable to take up water vapour from the atmosphere this finding is important evidence to support the suggestion that the survival of the egg stage largely determines the spacial distribution of larvae in the field. 13. Results of work done at constant, alternating and naturally fluctuating temperatures and humidities demonstrated that the duration of the incubation period of B.decoloratus is temperature dependent and humidity independent. The significance of this is discussed in relation to the findings of previous workers and to the biology of the species. 14. Egg viability (percentage hatch) was found to be humidity dependent and temperature independent. The implications of these findings are discussed. 15. Some of the problems associated with the assessment of the effects of climatic conditions on ticks are discussed. Special reference has been made to the advocation of using saturation deficit instead of relative humidity as the parameter indicative of environmental humidity in any biological study involving fluctuating humidity conditions. 16. The problems associated with having three variables (e.g. temperature, saturation deficit and incubation period duration) are discussed and reasons given for why contour diagrams have been used in this investigation. 17. A model of the interactions between the main abiotic factors of the environment (temperature and humidity) and the biological parameters studied during the second part of this investigation is presented. 18. The effects of climatic conditions on the life cycle and distribution of B.decoloratus are discussed. Special reference has been made to the available evidence explaining the summer build-up in tick numbers known to occur in nature and the way in which the present findings have helped in an understanding of the spacial distribution of B.decoloratus in the field.

- Description: From Introduction: Precipitation of energetic particl es into the upper atmosphere is known to cause aurora at high latitudes. Sanae is situated in the vicinity of the South Atlantic Geomagnetic Anomaly (Gledhill and Van Rooyen (1963)) where the magnetic field intensity is very low and it is felt that this phenomenon may enhance the loss of particles from the trapping zone into the upper atmosphere. Previous work at Rhodes has shown that it is extremely likely that particle precipitation could be the cause of some ionospheric effects at Sanae. Gledhill and Torr (1966) found that a "disturbed" ionosphere at Sanae was linked with "high" fluxes of precipitated electrons in the area conjugate to Sanae. Later papers by Gledhill, Torr and Torr (1967), and Torr and Torr (1967a, 1968a) established that electrons are precipitated over a large part of the earth's surface and this phenomenon is probably responsible for an average of about 30% of F-layer disturbances. The frequency of precipitation and corresponding disturbances is most pronounced in the South Atlantic Geomagnetic Anomaly . , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

Certain aspects of eroticism in twentieth century western painting

- Description: In this essay eroticism will be examined as it appears in some twentieth century representational styles. The decision to concentrate on the representational styles is based on the fact that eroticism is by nature incompatible with the non-representational or non-objective movements in art. This incompatibility is rooted in the knowledge that eroticism is intrinsically and fundamentally a human experience and could therefore find expression only in an art which is concerned with human experience, i.e. experiences which refer to man, his nature and his relation to Nature. It would be oversimplified and grossly inaccurate to equate the nonrepresentational with the abstract, abstraction being an element present in all art to a greater or lesser degree. However, when abstraction has reached the stage where it can define its aims, as, in the words of Kandinsky, "widening the separation between the domain of art and the domain of Nature", (Lake & Maillard: A Dictionary of Modern Painting, p. 1) then it may also approach the realm of the non-representational. When Michel Seupher states, "I call abstract art all art that does not recall or evoke reality", (Lake & Maillard: A Dictionary of Modern Painting, p. 136) abstract and nonrepresentational art becomes fused into an inseparable unity. Erotic expression will then be incompatible with this degree of abstraction. Intro., p. 1.
