A contribution to the biology of warthog (Phacochoerus africanus, Gmelin) in the Sengwa region of Rhodesia

  • Authors: Cumming, D H M
  • Date: 1971
  • Subjects: Warthog Warthog -- Physiology Warthog -- Ecology

  • Description: To the AmaZulu a warthog is "inhlovudawana" or "little elephant"; to arrogant hunters it is the "poor man's rhinoceros"; to some writers of encyclopaediae it is a "grotesque and hideous beast"; to stockmen it has long been a carrier of diseases. Injury was added to insult with the discovery that the blood of these self-assured, often comical and certainly engaging animals supports the greater proportion of tsetse flies in the African savannas. Their significance as the primary hosts of Glossina morsitans Westw., the vectors of tryanosomiasis, justified an extended field study of warthog biology. This thesis reports four years of field work on warthogs, together with complementary observations of hand-reared warthogs (and their offspring) which roamed freely in the vicinity of the remote field station on which I live. The Sengwa Research Project, of which this study forms a part, was initiated in 1965 to study relationships between game animals and tsetse flies. One of the main problems investigated in the Sengwa Project is that of "host encounter" (Glasgow, 1961, Bursell, 1970) and how the distribution, abundance and behaviour of game animals may affect their availability to hungry tsetse flies. I have, accordingly, been concerned with discovering how warthog are dispersed in the Sengwa area and have attempted to gain some understanding of the factors, both environmental and social, which may affect or govern their dispersion and possibly population number.

  • 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.

  • 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.

  • Description: From Chapter 1: Even before the publication of The Poems of Emily Dickinson in the variorum edition by Harvard University in 1955, under the editorship of Thomas H. Johnson, there was a steadily growing interest in the work of this poet and in her position both in the sphere of American literature and in the larger field of English poetry. In 1957, The Letters of Emily Dickinson appeared, with Johnson as editor, and Theodora Ward as associate editor. With this publication critical literature received an incentive to increase and extend the exploration already undertaken.

  • Description: For purposes of this background study, previous research findings relating to the development of the concept of field dependence - independence may be traced in five clearly distinct and logical stages: Stage 1: The Determination of the Factors Responsible for the Maintenance of Proper Orientation to the Upright. 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: Why teach music? To answer this question one has to be able to see the full value of musical education. One has to recognize its effect on the unfolding of character and personality on the one hand and, on the other, its value for the development and sharpening of the intellect. In ancient Greece, the cradle of Western culture, the significance of music for man, the people, and the state was frequently emphasized. The Greeks regarded music almost as a magic force, the inherent harmony of which was capable of transforming things and creating order by reconciling contrarieties. Similarly they believed that the power of music could restore the harmony in man's soul. Intro., 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.

An investigation into the relationship between creativity and academic performance in school children

  • Description: The subject of creativity is of interest not only to the research worker and educationist but also, with its related mental health aspect, to the clinical psychologist. As the writer's interest is in clinical psychology the opportunity, which occurred in 1968, to undertake research on creativity, was welcomed. This opportunity arose out of a larger piece of research into the relationships between personality variables and mathematical ability in school children. This involved the administration of personality tests and tests of arithmetic and mathematical ability to all the English speaking school children in Grahamstown from Standard 2 to Standard 10. The writer assisted in this testing program and did the greater part of the marking, scoring and entering on computer sheets. Thus personality test scores for over 2,000 children from the age of 8 or 9 to 17 or 18, both boys and girls were available. It was found possible to extend the computer program to calculate a score for creativity based on a combination of Cattell's personality factors and it was decided to compare these creativity scores with actual school performance, as measured by internal school examinations, which with the cooperation and agreement of the Cape Education Department and local schools, the writer was able to obtain.

  • 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: 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.
