- Description: In the year 1877, during a lull in the Eastern Question, the English newspapers discovered South Africa. There a Dutch republic, the Transvaal, had all but succumbed to the onslaughts of a native chief - or so it seemed; and now it was annexed to the British Crown. Clearly, this was a corner of the world of which, as its colonists boasted, England would hear much more; and Parliament was shortly to set its seal of approval upon Lord Carnarvon’s essay in imperial architecture, South African Confederation. Intro., p. 1.

A cross-cultural study of susceptibility to the Müller-Lyer and Ponzo illusions

- Description: In order to investigate certain anomalies evident in the literature, the performances of three Xhosa groups (rural dwellers, urban dwellers, and undergraduates) of varying degrees of acculturation and a White undergraduate group, each group consisting of 30 subjects, were measured on tests of mode of field approach and susceptibility to the Müller- Lyer and Ponzo illusions. In addition, the effect of the introduction of a mental set, which facilitated the perception of perspective in the Ponzo figure, on susceptibility to the illusion was ascertained. Mode of field approach was measured by a portable version of the Rod-and-Frame Test. Susceptibility to the Müller-Lyer illusion was measured by a conventional movable- slide, subject-adjustable device, while a piece of apparatus which also worked on the movable slide principle and was subject-adjustable was developed to measure susceptibility to the Ponzo illusion. The set to facilitate the perception of perspective in the Ponzo figure was introduced by having subjects match the length of Ponzo contrast lines embodied in a photograph and a line-drawing of a bridge, both of these pictures having strong perspective cues. The subjects were required to perform the tasks in prescribed order. Standardised English or Xhosa instructions were ensured by the use of "programmed" worksheets for each task. Prior to each experimental task, the more unacculturated subjects performed comprehension checks to ensure that they understood the concepts of equal length and verticality. The results of the study suggested that: (i) When groups of differing acculturation levels are tested, there may be a pronounced negative association of field dependence with susceptibility to the Müller-Lyer and Ponzo illusions. In general, the more unacculturated the subject, the more field dependent and the less susceptible to illusions he was. However, there was no evidence which either strongly supported or refuted the relationship between these attributes at the intra-group level. (ii) There is no intra- group association between susceptibility to the Müller-Lyer and to the Ponzo illusions. This would indicate that they are not necessarily generated by similar inference habits or by similar contour properties. (iii) The introduction of a "perspective set" increases susceptibility to the Ponzo illusion only among acculturated subjects, who have well-developed pictorial depth perception skills and who habitually infer depth in inverted - V configurations. (iv) There is a significant association between acculturation and field independence. The unacculturated subjects, presumably because they lack the skills of visual analysis which are engendered by Western culture, were more field dependent than the acculturated subjects. (v) Provided that their degrees of acculturation are more-or-less equivalent, as were those of the two undergraduate groups, there are no differences in mode of field approach or susceptibility to the Müller-Lyer and Ponzo illusion among Xhosa and White subjects. Summary, p. 112.

Stage 11: The Investigation of Individual Differences in the Manner of Establishing the Upright. Stage III: The Consideration of Possible Hypotheses to Account for Consistent Individual Differences in this Mode of Perception. Stage IV: An Investigation of the Relationship Between an Individual's Characteristic Way of Perceiving and his General Personality Organisation Stage V: The Ultimate Extension and Elaboration of this Work into the Construct of Psychological Differentiation which proposes that individuals are likely to function at a more differentiated or less differentiated level in many areas of behaviour. Some discussion of these stages is necessary to provide background for the present study. Chapter 1, p. 1.

- Description: Most eye drops are dispensed in multi-dose containers, hence protection should be given against microbial contamination during use. To remain sterile during it's use, the solution should contain a preservative in such concentration so that it kills micro-organisms in a short time. It has been stated in the literature that the instillation of contaminated eye drops constitutes a greater danger than the intravenous injection of a contaminated solution since the cornea is nonvascular and lacks the normal antimicrobial defences of the blood stream. Amongst the preservatives used, those included in the official formulations for eye drops are Chlorhexidine Acetate, Phenyl Mercuric Nitrate, Benzalkonium Chloride, and to some extent Phenylethanol, which may be used in combination with Benzalkonium Chloride. The main purpose of this investigation has been to determine the adsorption of these preservatives by different filters during sterilization by filtration. Part 1, p. 2.

- Description: Two labdane diterpenoids 8-hydroxymarrubiin and leonitin were isolated from Leonotis dysophylla (Benth.) and Leonotis leonitis respectively. Spectral studies of 8-hydroxymarrubiin, C₂₀H₂₈ O₅ʻ showed the presence of a β -substituted furan, a Ϫ-lactone, three tertiary methyl groups and tertiary hydroxyl group (s). The NMR spectrum of 8-hydroxymarrubiin and marrubiin C₂₀H₂₈O₄ʻ were almost identical with the exception of the C₁₇- methyl group which appeared as a singlet in 8-hydroxymarrubiin and as a doublet in marrubiin. The extra oxygen atom was therefore assumed to be present as a hydroxyl group substituted in the C₈₋ position. This was further confirmed by the formation of an epoxide and a Ϫό-dilactone. Leonitin, C₂₀H₂₈O₇ʻ was shown by spectral and chemical evidence to be a diterpenoid dilactone possessing an ester function and an ether linkage. Comparison of the NMR spectra of compound X and leonitin suggested that the acetoxy function occurs in the C₂₀- position. This was further supported by the formation of a 'Ϫό -dilactone. The absence of a β -furan moiety was apparent from chemical and spectral evidence, A structure for leonitin is proposed and aspects of its stereochemistry discussed.

- Description: Two labdane diterpenoids 8-hydroxymarrubiin and leonitin were isolated from Leonotis dysophylla (Benth.) and Leonotis leonitis respectively. Spectral studies of 8-hydroxymarrubiin, C₂₀H₂₈ O₅ʻ showed the presence of a β -substituted furan, a Ϫ-lactone, three tertiary methyl groups and tertiary hydroxyl group (s).

- Description: From Introduction: Wax and wax-like substances have been defined in many ways. One reasonably extensive definition, by Hatt and Lamberton (1956) is given below: "The term "wax" seems best used to denote a group of substances which qualitatively have certain physical properties in common. These properties are familiar ones, for in almost all countries some natural wax - beeswax, Japan wax, Chinese insect wax, the carnauba and candelilla waxes of the Americas - has been an important material in art and industry from prehistoric times. Waxes are understood to be opaque or translucent solids, which melt without decomposition to form mobile liquids at temperatures in the region of 100⁰C. They differ in hardness, but are all essentially soft substances with poor mechanical strength. Most waxes can be easily shaped or kneaded at a little above ambient temperatures. In fact, the term could easily have been made to cover the whole class now named thermoplastics." Pure n-paraffins would be too crystalline and brittle for use as waxes, whereas mixtures of n-paraffins have some valuable properties. The molecules bear such close resemblance to one another that they form mixed crystals of lowered crystallinity and the melting point is a function of the mean molecular weight. This is a desirable feature for it permits crystallinity and brittleness to be reduced without a marked loss in the melting point or hardness. It also allows a mixture to simulate a pure compound very closely. Waxes, in general, have been put to a large number of uses. They are used, for example, in candles, polishes, paper-coating, plastics, printing, matches, rust protectants and insulation. Each application requires its own appropriate range of wax properties.

- Description: While there are studies of the Border region, which give a picture of the economic, industrial, and physical features of the dominant centre of East London and of its Bantu population, no detailed study of the White population of the city had, prior to 1954, been published. So it was that in 1964 the present study was commenced as primarily a sociological analysis of the White population of East London. It was designed to deal with this gap in our knowledge of the region. The study includes a description of the historical development of the city, and some reference to its regional setting. The White population of the city is analysed in some detail. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: From Introduction: For many years I have been interested in the relationship between ethical and moral attitudes and values and religious belief. I became aware of a conflict in attitudes concerning the role of the Church in society as a member of the Methodist Church, and this stimulated me to study seriously the role of the Church in present day society. I found that members of the Wesley Guild, of which I myself was a member, conceived of the Guild in three forms: (a) as a social club; (b) as an institution for training in Christian service, both at the level of spiritual belief and practice and at the level of practical help to those in human need; (c) as an assooiation where individual spiritual values are fostered. Members differed in their view of the Guild, some seeing it in terms of all three enumerated forms, others emphasising one or two of these forms. This induced tension within the Guild. Wider observation led me to the view that this diffused concept of the Church and its functions was not peculiar to the Wesley Guild. It seemed to be general to the South African Church. I became confirmed in this view when, as a student at Rhodes University, I found that many theological students of different denominations shared it.

- Description: This dissertation offers fairly full readings of three early Shakespearean comedies. Because these works are still partly misunderstood, it has seemed reasonable to lay the critical emphasis on explication, though a certain amount of judging has been inevitable. The aim has been to induce recognition of aspects of these plays to which much modern criticism has seemed opaque.

The archetypal fable : an inquiry into the function of traditional symbolism in the poetry of Edwin Muir
- Authors: Gillmer, J E
- Date: 1970
- Subjects: Muir, Edwin, 1887-1959 -- Criticism and interpretation
- Language: English
- Type: Thesis , Doctoral , PhD
- Identifier: vital:2297 , http://hdl.handle.net/10962/d1011975
- Description: Edwin Muir's poetic vision is bound up with that belief in a twofold structure of reality that in European culture has been called Platonist but which is so ancient and widespread that no one can determine its origins. Though no longer fashionable in a time when materialist philosophies flourish and even Christian clerics are busy "de-mythologizing" their faith, it has been the potent source of our greatest poetry and perhaps, as Kathleen Raine believes, of all true poetry. Those who hold this conviction regard the sensible world as the reflection of an "intelligible" or spiritual world which gives meaning and purpose to life, and they see the objects of nature as images that evoke the ideal forms of a divine reality. For poets, as for traditional men, this belief is less a metaphysic than an intuitive way of apprehending and ordering experience, a "learning of the imagination" inherited from ancient and mysterious sources. To Muir it came directly and spontaneously in the symbolic images of dreams, and the fact that he entitled the first version of his autobiography The Story and the Fable testifies to the importance, both for his life and his poetry, of his belief in two corresponding orders of experience. Intro., p. 1-2.
