- Description: The aim of this research is to investigate intellectual development of a group of Black mineworkers on a South African gold mine, in the light of their exposure to a technical industrial environment. The research was conducted within a Piagetian framework and attempts to establish:- 1. A conceptual profile which would highlight the subject's conceptual abilities in relation to job skill requirements. 2. An empirical analysis of combined Behavioural and 3. Explanatory responses to support the hypothesis that experienced Black mineworkers should perform better on the diagnostic battery than novices: the main reason for this being the contention that conceptual development is facilitated by cognitive adaptation to the demands of a selectively different technological environment. Whether the battery of Piagetian conservation tasks could be evaluated for use as conservation scales with sound statistical properties. A random sample of fifty six Black mine workers was realised and their performance indicated that:- a ) The concept of Force is not actively developed by mining. b) There was no significant difference in the performance of Novice and Experienced subjects. c) The diagnostic battery in its present form is inadequate and would have to undergo some relative modifications. d) Conceptual profiles showed that concept areas tapped were not developed past the stage of Concrete operations, and that in some instances subjects did not conserve concepts which are relevant to the occupation they were selected for on the Classification Test Battery. e) Piagetian methodology could only be selectively applied to the mining industry for purposes of selection and placement. f) Conservation scales were not realised because of anomalies found in the composition of sub-concepts in the battery. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: The nominal species Petrotilapia tridentiger Trewavas, a rock-frequenting fish from Lake Malawi, occurs in three distinct male and female colour forms at Monkey Bay. Field observations on courtship and aggression indicate that the three colour forms are distinct species. The taxonomy of the three species of Petrotilapia that occur at Monkey Bay is revised. R. tridentiger is redescribed and two new species, P. genalutea and P. nigra, are described. The three species are very similar morphologically and are considered to be sibling species. The only morphological character which reliably separates the three sibling species is live coloration: Live coloration is considered to be an important component of the specific mate recognition systems in Petrotilapia species. The coloration of a further fourteen forms of Petrotilapia is described and it is suggested that these forms are valid species. Space resource partitioning plays an important role in facilitating the coexistence of Petrotilapia sibling species. Space is partially partitioned in terms of depth range. In shallow water, where all three species are sympatric, there are differences in the feeding sites used by the various Petrotilapia forms. Changes in niche breadth and overlap, which are associated with changes in the abundance of epilithic algae, indicate that competition for feeding space occurs between the three Petrotilapia species. The Petrotilapia species partition their resources according to a social dominance hierarchy. Dominant forms, such as territorial males, R. tridentiger females and schooling R. genalutea females, have access to rich food supplies which occur within the territories of certain highly aggressive Pseudotronheus species. are facultative and opportunistic .feeders. Petrotilapia species Speciation in allopatry is considered to be the mechanism which adequately explains the current diversity of the genus Petrotilapia. The importance of an integrative approach to future systematic and ecological research on Lake Malawi cichlids is stressed. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

A commentary on Nepos' Life of Alcibiades

- Description: From Introduction: Much of the commentary is historical and biographical in its emphasis. In making detailed reference to other accounts , I have tried to fill important gaps in Nepos' brief and (in places) abrupt account, to compare the picture of Alcibiades in his account with that of other accounts and to trace sources which he may have used important passages have been quoted in full so that verbal similarities can be seen. A striking feature of Nepos' work is his tendency to describe many non-Roman situations in Roman terms. This reflects not only his vagueness about details (a common fault in his writing), but also perhaps a desire to make his Lives more relevant to his reading public and thus more readable. From antiquity to the present day biography and history have tended to be distinguished from each other, and biography has had the greater popular appeal. Readability is perhaps the most abiding quality of Nepos' Lives and Alcibiades may be the most readable of them all. On the whole Nepos portrays him consistently, although of course he also emphasises the inconsistency which was such an important part of his nature. He has told the story simply, yet dramatically; many of the complicated details about Alcibiades are omitted, yet particular incidents are highlighted, notably the return to Athens and the assassination. Above all, from Nepos' Life there emerges the impression that Alcibiades was unique and worth writing about.

Being in therapy has brought about extremely important ·changes in my life and continues to do so. Being involved · in the field of· psychology as a student and therapist-to-be, the experience of therapy has also been a valuable source of a greater understanding of the process itself. The various facets of the importance of my experience of psychotherapy will become clear in my explication. It is a fact that experience, which is an essential aspect of our humanness, has been sadly neglected in psychological research. It is surely psychology's task to explore all aspects of humanity, and this neglect of experience has only fairly recently been questioned. Its reasons have been psychology's bias towards the natural sciences whose methods are not suitable for the study of experience. The tremendous achievements of the natural sciences caused psychology to adopt this slant, as Sigmund Koch (19.69) puts it, "The stipulation that psychology be adequate · to science outweighed the commitment that it be adequate to man".

An ecological study of territoriality in four Cichlid species resident on rocky shores near Monkey Bay, Lake Malawi

- Description: This study centres on a diverse assemblage of epilithic algal grazing fish (17 cichlids and 2 cyprinids) found on the rocky shores near Monkey Bay, Lake Malawi. Diet overlap among these species is large, but competitive exclusion is apparently avoided by the species having different feeding structures, behaviour and distribution on the shore. In many respects the ecology and behaviour of the cichlid fishes inhabiting the rocky zones of Lake Malawi parallel those of coral reef fish. In both communities there are species which are highly territorial, resulting in resource subdivision and, in some cases, the development of algal gardens. As this behaviour has not been previously reported for cichlid species, this thesis describes the territoriality of the rock-dwelling cichlids of Monkey Bay, Lake Malawi, and poses three specific questions: 1. What is the function of territoriality? 2. How do the territorial species subdivide the space resource? 3. What prevents one species taking over all the available space? It is suggested that interspecific territoriality evolved in response to a shortage of food, and, at present, serves principally to defend an algal garden i.e. a food supply of high standing crop. The species studied are extremely site specific. The rocky shore is subdivided among the four species according to the rock configuration, size, algal mat composition and position on the shore, of the available sites. An experimental study of the space utilization of the two common territorial species, referred to as 'Pseudotropheus orange cheek' and 'Pseudotropheus aggressive', showed that suitable territory sites are in short supply and that these species are in competition for some sites. These results do not support those of Fryer (1959) who suggested that a superabundance of food enabled fish to coexist by sharing the same food resource. Indeed it now appears that a shortage of food may have been a major driving force during the recent evolution of the species studied.

- Description: During the Angolan War of 1975-6, whilst South African troops were actively engaged on the side of the Unita/FNLA alliance, news media in South Africa were prohibited from disclosing information about the country's role in the war. Under Section 118 of the Defence Amendment Act of 1967, no information about SA troop movements or plans could be published without the permission of the Minister of Defence or his nominees. This case study shows how the Government used the Defence Act to censor certain news while releasing other news which suited its political outlook and objectives. The study documents the history of the Defence Act and of the military-press liaison machinery which grew out of it. The introduction defines propaganda as a technique of ideological control designed to supplement the control of society by means of repression. The study sets in context the Government's propaganda strategy before, during and after the Angolan War, arguing that the structures of white domination, including the newspaper industry, are being drawn into the Government's scheme of total co-ordination to fight a total war.

Gehoorverlies plaas die individu in 'n situasie van vereensaming, veroorsaak deur 'n beperktheid in kommunikasievermoë. (Roux, 1979:1) Dr Roux, Direkteur van Gesondheidsdienste van die Departement van Gesondheid, Welsyn en Pensioene, het tydens die Goue Jubileum-Kongres van die Suid-Afrikaanse Nasionale Raad vir Dowes daarop gewys dat gehoorverlies vandag meer Amerikaners affekteer as hartsiektes, kanker, blindheid, tuberkulose, veneriese siektes, sklerose en niersiektes tesame. (Roux, 1979:1) In Suid-Afrika word beraam dat 0,06% van aIle babas totaal doof gebore word en dat die aantal persone met ernstige gehoorprobleme, volgens die skatting van die Departement van Gesondheid, Welsyn en Pensioene, 65 000 beloop. Hierdie getal sluit Swartes uit. (Roux, 1979:1) ... Die probleem van doofheid is kompleks en soms so ingewikkeld dat dit te betwyfel is of die horende individu die omvang daarvan begryp en insig in die situasie van die dowe kan ontwikkel. Empatie met die dowe en begrip vir sy leefwêreld is vir die horende persoon problematies. 'n Wêreld sonder klank is moeilik om te visualiseer en 'n wêreld sonder taal lê buite die begripsvermoë van die horende. Daar bestaan op velerlei gebiede verwarring ten opsigte van die dowe. Die horende persoon besef gewoonlik dat daar 'n eiesoortige wêreld van ervaring en denke vir die dowe is anders as die van die horende, maar begrip vir die omvang van die andersheid van die dowe ontbreek.

Empatie met die dowe en begrip vir sy leefwêreld is vir die horende persoon problematies. 'n Wêreld sonder klank is moeilik om te visualiseer en 'n wêreld sonder taal lê buite die begripsvermoë van die horende. Daar bestaan op velerlei gebiede verwarring ten opsigte van die dowe. Die horende persoon besef gewoonlik dat daar 'n eiesoortige wêreld van ervaring en denke vir die dowe is anders as die van die horende, maar begrip vir die omvang van die andersheid van die dowe ontbreek.

- Description: The mind and character of an individual can be fostered by the subjects which have proved themselves to be of value in improving the education of man, not only from scientific, but also from moral and aesthetic stand points. The question is whether or not geography as a subject fulfils this requirement. For this it must have a distinctiveness of aim and a limitation of content. Civilization today is passing through great crises. Wars, rumours of wars, cold wars, economic crises, exhaustion of natural resources etc. are reported daily in the newspapers. Education of a certain type is needed - an education which will develop in man a deep concern for the freedom and good life of his fellows, and some understarding of the major problems of the world and possible solutions. Man is no longer a unit of a small self-contained community, but has his responsibilities as a citizen, firstly of his own country and secondly of a world community. Upon his solutions to the problems of the world depend to some degree the progress and development of his town, country, of the world generally. Education therefore ought to train the child to take his place in the world, not only as a man, but as a citizen. Children must be taught to think and reason for themselves. Geography as a subject lends itself magnificently to the general education of men and the development of good citizens. Geography can help to teach pupils to understand and experience the adult world. South Africans are fortunate in that geography is a compulsory subject up to standard seven. In high school beyond this level it is not offered by all schools.

- Description: From Introduction: To learn to focus on the other, I first have to learn my natural limits. Unless my natural limits are found, I cannot focus on myself or the other with freedom. I will either draw back or intrude. As I learn my natural limits, I free the energy I previously used in questioning limits. Having recognised that I am bounded, the effect of my released energy is to deepen my space. The infinity which used to lie beyond the horizon is brought into the realm of the human where it can be useful. As a psychotherapist the deepening (that is differentiation) of my own space is very important. It means that the space I share with the other is better explored and better known. The raw data for this thesis is a record of 2½ weeks of intensive psychotherapy and 3 weeks of intensive explication. During this time I explored the interrelated themes of my own limits and the particular shadowedness of the space I shared with Tony, the person in psychotherapy with me.

- Description: An investigation of the reaction of the sulphuryl chloride-N, N-dimethyl formamide reagent with several carbohydrate compounds, containing free hydroxyl groups, was undertaken, mainly with the view of looking at substitution of the hydroxyl groups with chlorine atoms. The reaction was found to lead to substitution of both primary and secondary hydroxyl groups with chlorine, with inversion of configuration in the latter case. The reagent was further found to effect formylation and chlorosulphation of secondary hydroxyl groups, where nucleophilic substitution by a chlorine was not favourable. Studies involving the methyl pentopyranosides, showed that the reagent was particularly useful in the chlorosulphation and chlorination of sugars, compared with the hexopyranosides.

Some observations on Wordsworth's achievement in sonnet

- Description: From preface: This study seeks to give a perspective on Wordsworth's achievement in sonnet, taking into account all the sonnets he wrote, from the outburst of sonneteering in 1802 to the final decade (1840-1850). My chief concern has been to trace Wordsworth's handling of form and theme throughout his poetic career. A subordinate but related concern has been to try to show that Wordsworth's powers do not diminish after 1815, a date which is sometimes regarded as marking the beginning of the poet's "decline" ~ Wordsworth’s skill in blank verse and in other types of lyric is widely acknowledged; his dexterity in the sonnet form is less well recognized or thought to be limited to fewer poems (usually those of the earlier years) than there actually are. As a result, his performance in sonnet is sometimes underestimated, there being more sonnet concerns and structural patterns than the well-known few reflect. It is possible that Wordsworth's own ambiguous attitude to the genre as expressed in his prose writings, together with his insistence that his sonnets were not amongst the best of his poems, has helped to foster such a view. His practice in sonnet, however, proves that his genius is as evident in some of these poems as it is elsewhere, whether he esteemed them less or not.

The diaries of Thomas Shone: 1820 settler, 1838-39 and 1850-59

- Description: I first read the diaries of Thomas Shone in 1971, when working on manuscripts in the Cory Library, Rhodes University, for the Dictionary of South African English on Historical Principles. The diaries were a significant source of South African English; but more than that, they created a moving and vivid picture of one man's life and personality, which made a deep impression. Written daily (unlike many other settler writings, which are reminiscences), the diaries proved to be a journey into the interior life of Thomas Shone, with all his guilt, pain and occasional joys, documented in his idiosyncratic style. Photographs show Thomas to have been a man with a determined, even hard, mouth, and piercing eyes under rather lowering brows. If he was like his son, Thomas junior, he was "erect and bright", and of the "typical Shone build, rather stumpy and fairly broad." His command of language suggests a good education and a sharp intellect, strangely at variance with his description as a labourer. His writing is imbued with the archaic ring of the King James Bible, and much of the charm of the diaries lies in their movement between the sublime and the mundane, as when Shone breaks a discussion of his need to be faithful to God, to note that "Sarah sat a hen on 22 eggs." Shone's diary is an intensely personal document, yet there are signs that he was at times conscious of a possible audience. His use of the phrase "My friends" to address his readers " is likely to have been part of a convention of the time, rather than overt acknowledgement of the presence of an audience; however at the most personal level of all, his relationship with his mistress, he was not explicit, but employed a form of code (.∶.) Furthermore, there is evidence that he kept a rough diary, from which he later made a neat copy. Thomas began his diary in order to record his attempt to stay away from drink, but his writing soon came to mean more to him than this. He gradually introduced notes on his daily activities, and his temptation to drink became just one part of a personal history. From 5 August 1838, when he first wrote of the loss of his wife, the diary became an important outlet for his misery. Despite his unhappiness, Thomas took delight in the use of sarcasm and wry humour to comment on the foibles of humanity. "Me and Billy went to Mandy's; I cut my thumb and three trees", he wrote; and "Indian corn bread makes my belly ache... (My relations have the mind ache; I believe it is worse than the belly ache.)" "Religion is flying away to other parts as fast as it can; the religion here is money, and Cattle and a covetious Spirit for other men's goods ", he grumbled of the Clumber community. The most effective (and prolonged) use of his gift for sharp conment may be found in his description of the watchnight service at Clumber. Shone seems to have possessed a natural flair for language, and used metaphor and simile to good effect, as in the following examples: "Now am I like a dove that as lost his mate"; Every thing seems quiet; I have still a war in my mind"; "Riches very often finds wing and flys away"; and "My mind is like the troubled sea, never at rest". He often showed an affinity for rhythm and alliteration, probably as a result of his familiarity with Biblical English: "These are my days of grief and sorrow"; "poor poverty"; and "Hard is my fate... all things seem to go contrary, strive which way I will." These examples of language provide a strong contrast with his reporting of everyday activities: Shone changes from one linguistic register into another in his movement from introspective to factual writing. At times Shone achieves an extraordinary vividness in his description of small incidents, as in his stories of encounters with monkeys, or his report of an altercation with his son Jack. One of the loveliest passages is his account of a day spent on his old location at Scott's Bottan. Thomas was "political" only insofar as politics touched his own life. For the political historian the diaries are frustrating; except for his descriptions of the War of Mlanjeni, Shone shows little interest in the wider issues of his time. However, the diaries show the complex web of relationships in a small community, and give insights into commercial interaction, domestic activities, marriage ties, religious attitudes, family behaviour and interpersonal conflicts, all set within the political tensions of the frontier society. As the diaries progressed, and Thomas Shone aged, he weed from being an active participant in the life of the frontier, to being an onlooker and commentator. Possessed of a mind (and tongue) which isolated him from many of his neighbours, he was no doubt also separated from his community by his relationship with Ann Hiscock and by his heavy drinking. The diaries became his vehicle for expressing the inexpressible; and in the end it was religion which gave him solace. It is the "interior" diary which provides much of the fascination which Shone's writings hold for the modern reader. Professor Guy Butler has pointed out that writing was a secondary activity for the settlers, whose chief preoccupation was survival in a difficult environment. Shone's diaries certainly reflect his economic struggle; but it is their portrayal of his pilgrimage through life which makes them remarkable.

- Description: [From introduction] Exploration geochemistry is an indirect method of detecting mineral deposits by measuring the abundance and distribution of ore elements and elements closely associated with ore in natural materials at or near the earth's surface. The method relies on the assumption that a mineral deposit is reflected by unusual element abundances or distribution patterns (geochemical halos), and that these indications of mineralization can be detected by geochemical surveys involving the collection and analysis of natural materials. The interpretation of geochemical surveys in mineral exploration involves: 1) The use of geological and statistical inference, based on a knowledge of the normal behaviour and distribution of indicator elements in the exploration area, to recognize apparent geochemical anomalies in field and analytical data and to predict the type of geochemical halo reflected by the anomalies. 11) The use of geological inference, based on a knowledge of the characteristics of geochemical halos and their relationship to mineral deposits, to predict the presence and probable location of an ore body. The interpretation process is, however, complicated by the absence of a simple universal formula that relates the abundance and distribution of elements in natural materials to the presence or absence of a mineral deposit. The interpretation of a geochemical survey must, thus, be based on an empirical approach which avaluates each survey as an individual problem. The objective of this dissertation is to illustrate the factors affecting the "nuts and bolts" approach to the interpretation of geochemical surveys in mineral exploration. The discussion is aimed at providing field geologists responsible -for the planning and execution of geochemical surveys with some basic guidelines for interpreting the surveys. I hope that the contents of this dissertation will help field geologists to "look in the last place first".

- Description: Introduction: In South Africa, much of the work on algal limitation in man-made lakes has centered on nutrients rather than the possible effects of physical factors such as turbidity.In order to determine which is the most important factor in algal limitation in the turbid Orange River system, a comprehensive study of spatial and seasonal changes of the following factors was undertaken in the P.K. Ie Roux impoundment: trace elements , silicon, nitrate, phosphate, total phosphate, phytoplankton standing stock, total suspended solids, secthi disc transparency, light attenuation and the spectral quality of the light. None of the chemical factors appeared to be in short supply but the shallowness of the euphotic zone (0.8 m) had two effects. Firstly. the quantity of light in the upper 1.5 metres was extremely small due to the rapid attenuation of the light by silt. Secondly. the quality of the light was poor due to the selective screening of the shorter wavelengths of light. Once light limitation had been implicated as an important factor in the control of phytoplankton stocks a series of column experiments were used to demonstrate that increased circulation rate. and therefore a higher light dosage. would elevate the algal standing stocks without the addition of nutrients. It was demonstrated that light. as a result of the negative effects of turbidity was the principal cause of low algal standing stocks within the impoundment. and not nutrients as has previously been suggested by other workers.

- Description: Introduction: In South Africa, much of the work on algal limitation in man-made lakes has centered on nutrients rather than the possible effects of physical factors such as turbidity.In order to determine which is the most important factor in algal limitation in the turbid Orange River system, a comprehensive study of spatial and seasonal changes of the following factors was undertaken in the P.K. Ie Roux impoundment: trace elements , silicon, nitrate, phosphate, total phosphate, phytoplankton standing stock, total suspended solids, secthi disc transparency, light attenuation and the spectral quality of the light. None of the chemical factors appeared to be in short supply but the shallowness of the euphotic zone (0.8 m) had two effects. Firstly. the quantity of light in the upper 1.5 metres was extremely small due to the rapid attenuation of the light by silt. Secondly. the quality of the light was poor due to the selective screening of the shorter wavelengths of light. Once light limitation had been implicated as an important factor in the control of phytoplankton stocks a series of column experiments were used to demonstrate that increased circulation rate. and therefore a higher light dosage. would elevate the algal standing stocks without the addition of nutrients. It was demonstrated that light. as a result of the negative effects of turbidity was the principal cause of low algal standing stocks within the impoundment. and not nutrients as has previously been suggested by other workers.

- Description: The gastric morphology of the white-tailed rat M. albicaudatus - was described in detail. The bilocular hemiglandular stomach consists of a papillated corpus, non-glandular PGP and glandular antrum. The antrum contains cardiac, fundic and PJ loric glands (suggesting limited glandular reduction during gastric evolution) while the FCE and PGP are lined with orthokeratin. The corpal papillae, which increase surface area for microbial attachment, have undergone a different type of keratinisation called physiological hyperkeratosis. Streptococci, Lactobacilli and unidentified anaerobic bacilli (which colonise papillary microhabitats) are autochthonous in the stomach of M. albicaudatus but P. vulgaris and Ps. flourescens are probably autochthonous. Early gastric development is innate but the rapid development of PB into papillae between 15 and 17 days suggests the presence of allogenic growth stimuli: possibly mechanical abrasion by solid food, low chalone concentration in the papillary basal cells and the influence of the APB. Stimulation by VFA presence, however, is unlikely due to the low concentration of these acids in the stomach (Summary, p. 225)
