- Description: A microcomputer risk analysis model is developed and used in an exploration - delineation simulation to analyse in particular the effects of geological factors on exploration mining investment alternatives. Analysis of results indicate that geological parameters can have profound effects on such investment alternatives and that the role of the geologist in determining and evaluating the significance of the various geological factors is critical. Simulation examples highlight some of the key geological parameters and show how changes in these parameters influence both the expected mean results and the standard deviations of such means. The risk analysis model provides an ideal means of conveying the importance of the different geoiogical factors on exploration - delineation - mining investment alternatives and may be used as a geological education aid

- Description: This piece of research is an attempt to evaluate the relationship between military 'success' and the psychological preparedness of recruits in terms of their self-concepts and locus of control orientations. The new recruit is forced to adapt to the military environment which will, in turn, attempt to change him into an effective soldier. It was noticed by the researcher, who was involved in military training at the time, that a number of recruits, even some with seemingly limited potential, coped well, while others who seemed to have the ability failed to cope adequately. Recruits completed questionnaires which provided the researcher with biographical data and background information. In addition, the Bledsoe Self-Concept Scale and the Nowicki and Strickland Locus of Control Scale were used in order to determine their self-concepts and locus of control orientations respectively, prior to the beginning of national service. Detailed unstructured interviews were also conducted with a sample of military personnel, to provide another basis for gathering data and for clarifying some of the issues involved. Briefly, the chief conclusion of this researcher is that a significant majority of 'successful' recruits in the military environment have a positive self-concept and an internal locus of control. On the basis of the above finding, it is suggested that there is a need to guide pupils about certain aspects of military life before they begin their National Service. There would seem to be a need for this guidance to be incorporated into the school curriculum, together with such practical aspects as cadets, shooting, etc. There is a shortage of this kind of research on the military situation in South Africa, and it is suggested that numerous issues in this field need to be researched for the benefit of future conscripts and the military alike.

- Description: From Introduction: "That man is an aggressive creature will hardly be disputed. With the exception of certain rodents, no other vertebrate habitually destroys members of his own species. No other animal takes positive pleasure in the excercise of cruelty upon another of his kind" (A. Storr, 1968 p. ix). It is a sombre fact that man is the cruellest and most ruthless specie that has ever walked on earth. We recoil in horror when we read the daily newspaper or in a history book of the atrocities committed by man, but as A. Storr puts it: "....., we know in our hearts that each one of us harbours within himself those savage impulses which lead to murder, to torture and to war." (p. ix). Our warranted concern with this phenomenon is portrayed by the tremendous amount of research in this field which can be sub-divided into two distinct categories. The first category consist of those that emphasize nurture in their attempt to gain a deeper understanding of human aggression, of which the behaviourists and social learning theorists are staunch supporters. Underlying their concern and endeavour is the personal belief that aggression is attributable to environmental factors. In short, they maintain that humans are not aggressive by nature and if one follows their argument to its logical conclusion it would allow for a sigh of relief and inspiration. Their research results indicate that well deliberated methods of control would most certainly result in the extinction or near extinction of aggression. The second category consist of those, notably the psycho-analytic school of thought, who emphasize nature in their understanding of human aggression and do not allow themselves the naivety of projecting aggression into environmental conditions and situations. In short, they argue that aggression is innate and serves a particular function in the psychological development of the human being. It is their contention that aggressiveness supports the individual in his drive towards independence. The aim of this paper is to present both stances and to broaden the perspective by introducing a view that straddles both nature and nurture. Following this view, of whom Rollo May (1972) is a strong supporter, to its logical conclusion would indicate that aggression is the result of nature as well as nurture and that it serves the function of re-establishing a sense of worth and significance that has otherwise been thwarted. Finally, this paper sets out to prove that aggression and violence "feeds on a low self- esteem and self-doubt" (Toch. 69, p. 212).

- Description: There is concern that school history is often purposeless, taught by chalk and talk and textbook methods, giving thin and unassimilated information. At a time when subjects are under increasing scrutiny and pressure to justify their existence as relevant in the school curriculum, many of the defects inherent in the 'traditional' approach to history have made it difficult to present a forceful and valid argument for its continued inclusion as a school subject.This has led to the adoption of new approaches which are designed to get pupils more actively involved in their learning. One such approach was adopted by the Schools Council 13-16 project in Britain. It laid emphasis on the methodology of the subject and identified five ways in which history could prove to be a useful and necessary subject for adolescents to study. These were: as a means of acquiring and developing such cognitive skills as those of analysis, synthesis and judgement; as a source of leisure interests; as a vehicle for analysing the contemporary world and pupils' place in it; as a means for developing understanding of the forces underlying social change and evolutioni and, finally, as an avenue to self-knowledge and awareness of what it means to be human (Introduction, p. ii)

- Description: Various aspects of the biology of the intertidal agarophyte, Gelidium pristoides, were investigated, with the aim of providing information that would assist in formulating a management policy for this economic seaweed resource. G.pristoides occurs as tufts comprising as many as 40 individual plants, representing all three conspicuous life history stages, that are linked by the intertwining of their basal creeping axes. Individual plants consist of a system of branched creeping axes, which is largely responsible for colonizing surrounding substrata, from which one or more erect flattened fronds arise. These erect fronds may reach a height of 15 cm, and are irregularly bipinnately branched. Internal vegetative anatomy is generally typical of the genus. Morphological variation in mature plants is limited to increased plant height and branch density during the summer season. A dorso-ventrally flattened creeping habit was seen during early recruitment on flat rock surfaces and limpet shells within grazer exclusion plots, which developed into typical erect plants. Although there is a close taxonomic affinity between G.pristoides and the low-growing Gelidium turf, which occurs on wave-cut platforms in the eastern Cape (both produce bispores), the turf appears to represent a genetically divergent ecotype of the typical G.pristoides habit. In the light of present observations, it is suggested that the recent inclusion of G.pristoides in the new Onikusa genus should be questioned. Reproduction in G.pristoides is typical of the genus, except for the production of bispores, instead of tetraspores, in the sporophyte generation. The smaller nuclei in the binucleate bispores, in comparison to carpospores, suggested they are the product of normal meiosis (meiospores). This was confi rmed by chromosome counts of germl i ngs deri ved from bispores (n = 13-17) and carpospores (2n = 28-33). Throughout the geographical range of the seaweed, the bisporophyte generation is dominant over the combined male and female gametophyte generati on by a ratio of about 3 : 1. This imbalance may be due to bispores. G.pristoides a greater germination success of carpospores over plants are fertile throughout the year, while at Port Alfred there is no apparent seasonality in spore release. Growth of carpospore and bispore germlings is similar under various temperature treatments in culture. Optimum temperatures for growth were from 15-23°C, which corresponds with the sea temperatures experienced within the geographical range of the species . At Port Alfred, growth (linear frond elongation) and standing crop levels were maximal during summer . Ory weight levels were significantly inversely related to both growth and ash levels. Agar contents (% of dry weight) were generally greater in summer (48% ) than in winter (30%), and were inversely correlated with thallus nitrogen levels. Agar contents of distal plant halves were higher (8-15%) than in proximal halves. Regrowth of G.pristoides to original biomass or standing crop levels after harvesting, is similar for plucking and shearing at different times of the year. Regrowth is more rapid after spring and summer harvests (2-3 months) than after winter harvests (4-5 months). During the summer season, harvesting at monthly intervals showed significantly greater total yields, and production rates (e.g . 3.13 g. dry wt. / m2 / day for plucking) than under 3-monthly intervals (1.42 g. dry wt. / m2 / day for plucking). In contrast, average yields per harvest were Significantly greater when recovery period was longer (e.g. 3 months). Quadrats that were completely denuded failed to recover after a year, while regrowth was also retarded with increased elevation on the shore. Agar contents did not differ Significantly between plucked (38%) and sheared (42%) plant material. G.pristoides is distributed from about 0 . 2-0.75 m above MLWS, with a reduction in stature and frequency corresponding to increased elevation on the shore. Frond elongation rates, germling survival and recruitment within grazer-exclusion plots, is retarded with increased elevation level. Plants transplanted above the normal vertical range of the seaweed became severely bleached and died, while plants transplanted below the normal range of the seaweed (sub littoral fringe) senesced due to overgrowth by the epiphytic encrusting coralline, Polyporolithon patena (Hook . et Harv . ) Mason . G.pristoides recrui t ment in the sublittoral fri nge was enhanced with the exclusion of grazers . However, successful recruits were displaced due to smothering by articulated corallines (e.g. Corallina sp. and Jania sp. ) . G.pristoides is largely restricted to cracks and crevices in the rock, and also occurs on a large proportion of the available shells of the limpet Patella oculus Born., and to a lesser extent, shells of the barnacle Tetraclita serrata. G.pristoides recruitment was significantly enhanced by the exclusion of grazers (using toxic antifouling paint barriers). G.pristoides recruitment within the exclusion plots was significantly greater on artificially attached limpet shells (almost 100% cover) than on rock surfaces (20-30% cover), which occurred largely within cracks and crevies in the rocky substratum. ly attached to limpet G.pristoides plants are significantly more strongand barnacle shells than to rock and epilithic encrusting corallines (Lithothamnion sp.). Removal of G.pristoides from limpet shells revealed pits of a uniform size in the surface of the shells, into which the rhizoidal attachment organs of the seaweed penetrate. It is concluded that the horizontal distribution of G.pristoides is largely controlled by grazers (and "escapes" from grazing) and resistance to dislodgement by wave action. Based on present results, and considering some of the socio-economic factors associated with the Gelidium industry in South Africa, suggestions are made concerning the management and long-term maintenance of G.pristoides resources in the eastern Cape.

- Description: The pepsinogens and pepsins of cobra, mole snake and puff adder have been studied. The pepsinogens of all three species fall into two distinct groups, here designated PI and PII. At least the latter group, in all cases, shows substantial microheterogeneity. Physicochemical studies suggest that the cobra and puff adder PII groups are more similar to each other than either is to the mole snake PII group. Kinetic studies indicate that, in the cobra and mole snake, the PI and PII pepsins differ in their Arrhenius activation energies. Such difference is smaller, or absent, in the case of the puff adder PI and PII pepsins. These characteristics of the pepsins are assessed in the context of the differences between the oral secretions of the three species studied. The suggestion is advanced that the puff adder's strongly proteolytic venom has influenced certain properties of its gastric proteases.

- Description: Part 1.Thesis: Chapter 1: The people of the Lumko district (the villages of Ngqoko and Sikhwankqeni) are AbaThembu, mostly of the Gcina clan cluster. Their history has caused them to be linked with (now vanished) San peoples in special ways, which have undoubtedly influenced their music. Chapter 2: The music of these people is centred around their religious and social life. This affects the way they classify their songs; and song classifications (and the way songs are used) affect their performance, in particular, the dance styles associated with the song classes. Chapter 3: A variety of musical instruments is used in the Lumko district, the most important being the musical bows. Once again, the use of these bows gives an insight into the musical influences that have affected the people historically. The ways the bows work are described, as well as ways to play them. Chapter 4: Overtone singing, not previously documented anywhere in traditional African music, is practised in certain ways by these AmaGcina. These, and other vocal techniques, are described. Chapter 5: From the terminology and the methods of conceptualisation about music in the Lumko district, it is possible to gain an insight into a truly Xhosa technical understanding of Xhosa music. Once again a historical insight is gained, because so many of the important terms are KhoiSan words. Chapter 6: A Western technological (i. e. musicological) understanding of the music is also necessary in a study of this nature. This chapter applies musicological concepts to an examination of the relationship between speech and song, of the usages in melody and scale, harmony theory, rhythm, polyphony, song form, instrumental roles and methods of performance. Chapter 7: This is the conclusion of the thesis. It sums up what has been studied: musical techniques, principles, the importance of Ntsikana 's song as a basis for musical comparisons, and the import of the historical aspects of the study - a possible glimpse of the music of the San. PART 2. MUSIC TRANSCRIPTIONS AND DESCRIPTIONS. The transcriptions of 62 songs provide the material for this study. The songs were chosen to represent all the major song classes used in the Lumko district, and to represent all the important music techniques as well. The songs are in fifteen categories. Each song is accompanied by its technical details, and sufficient commentary to make the song transcription intelligible and meaningful. Certain key songs are chosen as type-songs or other special examples, and are used as the bases for discussion on song style characteristics, principles of performance, bow adaptation, and so on. A general Introduction to Part 2 describes and accounts for the method of transcription, and also attempts to make it possible for the score reader not only to analyse, but also to perform the songs. In a further attempt to bring the transcriptions to life, a video recording of certain key songs and techniques, and audio tapes with examples taken from all the songs, accompany this study

- Description: This research studies the acquisition and development of specific reading skills in English by "Coloured" primary school children for whom English is a second language. This study involves both oral and silent reading research. Developmental trends in both modes of reading are compared with those established for reading in Afrikaans in order to ascertain whether any transfer takes place from Afrikaans to English. For analysis of data obtained from oral reading, this researcher adopted an error analysis method devised by Kenneth Goodman (1973), viz. Miscue Analysis (MA). Readers read a passage and their miscues were recorded. From the miscues this researcher established, for the different standards: the frequencies of miscues; readers' ability to associate sound and symbol; sensitivity to grammar; meaning access; and correction strategies. In the silent reading research, readers' performances in a test battery of eight sub-tests provide insights into the presence or absence of information processing skills. Readability levels (Singer and Donlan (1980), discrimination index and facility value (Heaton 1975), and Chi-Square Statistics (Roscoe 1969) determine the development of specific reading skills, viz.: utilization of textual cues; understanding cause and effect relationships and sequence; previewing and anticipation; scanning, referring and synthesizing; understanding text structure and coherence; understanding propositional development; understanding synonymy and antonimy; and understanding communicative value. Grellet (1981), Kennedy (1981), and Harri-Augstein (1982), inter alia, regard these skills as crucial to efficient text processing. Analyses of data show there are developmental patterns, but skills emerge 1 - 3 years late when compared with results obtained by Kennedy (1981 ) and develop at a retarded and erratic pace. The readers in all the standards have not mastered the skills sufficiently to process text efficiently. This research shows that Std 3 is a cut-off level where a transition takes place from lower-order to higher-order skills processing. In addition, Chi-Square Statistics show little transfer from Afrikaans to English; the skills develop independently in the two languages. Enquiry has identified various factors that influence skills deficiencies, viz.: syllabus prescriptions and problems of interpretation; teachers' understanding of the reading process and the methods employed; teacher-training progresses; materials prescribed for reading; and reading in the society. This research recommends ways in which short comings can be remedied

- Description: The Xhosa cattle-killing movement of 1856–7 cannot be explained as a superstitious ‘pagan reaction’ to the intrusion of colonial rule and Christian civilization. It owes its peculiar form to the lungsickness epidemic of 1854, which carried off over 100,000 Xhosa cattle. The Xhosa theory of disease indicated that the sick cattle had been contaminated by the witchcraft practices of the people, and that these tainted cattle would have to be slaughtered lest they infect the pure new cattle which were about to rise. The idea of the resurrection of the dead was partly due to the Xhosa belief that the dead do not really die or depart from the world of the living, and partly to the Xhosa myth of creation, which held that all life originated in a certain cavern in the ground which might yet again pour forth its blessings on the earth. Christian doctrines, transmitted through the prophets Nxele and Mhlakaza, supplemented and elaborated these indigenous Xhosa beliefs. The Xhosa and the Christian elements united together in the person of the expected redeemer Sifuba-sibanzi (the broad-chested one). The central beliefs of the Xhosa cattle-killing were neither irrational nor atavistic. Ironically, it was probably because they were so rational and so appropriate that they ultimately proved to be so deadly.

This period was chosen because sport and athletics originated and developed a social institution during that time and the First World brought progress to a temporary halt, after which there were many new developments. The Cape Colony became British in 1814, and it was British influence that played such a dominant role in the social history of the period.

- Description: [Conclusions] l) The two forms of human locomotion, walking and running, are distinctly different and in evaluating these gait patterns consideration must be given to this fact. 2) The impression created by the energy cost curves, that there is a single locomotor interface for both walking and running is a false one . There are two distinctly different locomotor interfaces, the walk-to-run interface and the run-to-walk interface. The former appears to correspond with the "metabolic intersection point" and therefore has some metabolic significance. The latter appears to be merely an "overshoot" of the walk-to-run interface and presently has no apparent metabolic significance. 3) Because the walk-to-run interface speed corresponds with the intersection point of the energy cost curves, physiological responses to walking and running at this speed do not differ significantly. However, cadence and stride length patterns for these two locomotor patterns are distinctly different at this point. 4) The identification of single physiological or kinematic factors during perceptions of exertion in any given situation is an extremely difficult if not impossible task. Perceived exertion should therefore be considered a multi-factorial concept and should be evaluated as such. 5) The use of relative speed as a technique for reducing inter-subject variability in physiological and kinematic factors is worthless unless diverse ranges in morphological linearity are a characteristic of one's subject pool

- Description: The investigation reported in the thesis concerns an area south and west of Graaff-Reinet, in the Cape Province. The research projec t identified the existence of four groundwater units. The aquifers predominantly occur in Beaufort Group sediments and the boundary of each unit is formed by dolerite intrusives or with topographical highs. The objective of the study was to quantitatively assess these units in terms of both quantity and quality for possible future development as a municipal supply for Graaff-Reinet. In order to achieve the objective, fieldwork was carried out involving a hydrocensus, geological mapping, drilling, aquifer testing and hydrochemical sampling. The analysis of these data revealed that the Sundays and Kamdeboo aquifer units are unsuitable for further development. The Moordenaars and Swart units, both of which produce good quality water, have a combined exploitation potential in the order of 30 000 m³ /d. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: This thesis deals with a set of compositions by C. P.E. Bach, referred to as "The Last Fourteen Rondos". Thirteen of these are contained in the collections of sonatas, fantasias and rondos for connoisseurs and music lovers. The fourteenth is a separate work, entitled "The Farewell From a Silbermann Clavier in the Form of a Rondo". After establishing the background and the history of these rondos, the thesis then proceeds to a detailed analysis of the various compositional aspects. First, it tries to explain the overall design of the rondos, a design which differs from that normally associated with rondo form. It then deals with the structure of the thematic material and shows Bach's preference for phrase parallelism and a relatively simple melodic and harmonic outline of the various subjects. Special chapters are devoted to the manner in which C.P.E. Bach treats the musical substance, namely, by means of Variation and by systematic development. A short chapter is then devoted to the fantasia sections, which are included into most of the rondos. It is in the field of harmony where C.P.E. Bach emerges as a most important forerunner of nineteenth century musical trends and, consequently, some detailed analyses form a major portion of the chapter dealing with harmony. Special attention is then given to the various aspects of C.P.E. Bach's style and, in particular, to the pianistic · traits. The thesis ends with a brief survey of the influence which C.P.E. Bach exerted on his contemporaries and on later composers.

- Description: Scheelite, wolfram Ite and cassIterIte mIneralizat ion is hosted wIthin numerous quartz-tourmaline-feldspar-fluorite veins at Van Rooi's Vley, N.W. Cape Province . MineralizatIon and hydrothermal alteration within, and around, these veins is hIghly complex and reflects the intricate interaction of hydrotherma l activity upon a structurally deformed sequence of ProterozoIc med ium to high-grade gneisses. Four distinct stages of alteration and mineralization occurred, including a l ate 'epithermal stage'. Although the location of mineralization was strongly controlled by st ructure, the concentration of mineralizati on was controlled by physicochemical variables, of which host-rock geochemistry was particularly important . Further W/Sn mineralization occurs on a local scale, some of which is spatia lly related to minor leucogranite dykes. Leucogranite bodies are not uncommon within the region and some are enriched in Wand Sn. By comparing FIB ra tio s,W/Sn ratios, the alteration mineralogy, the ore mineralogy and the Fe-content of tourmaline, the deposits within the Van Rooi's Vley area can be placed into a 'proximal' to 'distal' classification, with respect to a common source of mineralizing hydrothermal fluids. The Van Rooi's Vley deposit, whilst affiliated to greisen-style deposits, represents a ' distal' quartz-vein lode deposit. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in
