- Description: This thesis focuses on the development of an operational and theoretically eclectic concept of psychological well-being. A comprehensive research strategy was employed to examine various personality factors thought to be components of psychological health (i.e., the basis of the proposed concept). The general approach involved four major phases: (1) the clustering of various variables and identification of underlying key factors purported to be related to psychological health based on the writer's clinical experience and review of the mental health literature, (2) the formulation of an ~ priori concept of psychological well-being based on the operational definition of those factors, (3) the construction of an inventory designed to examine the proposed concept, and (4) the interpretation of the results and their implications for the development of the overall concept based on the examination of the factorial structure, validity and reliability of the inventory. The"a posteriori concept" evolved out of this process. The results of the present study indicate that the most valid and reliable factorial components of psychological well-being are self regard,interpersonal relationship, independence, problem-solving, assertiveness,reality testing, stress tolerance, self-actualization and happiness; social responsibility and flexibility emerged as questionable components of the a posteriori concept. The inventory which was designed to study the concept was successful in significantly differentiating various levels of psychological health. This way of conceptualizing and assessing psychological well-being has potential applicability for mental health practitioners and researchers.

- Description: This thesis investigates the subject of Heaven or Paradise in the De Fide Orthodoxa of St. John of Damascus (c.675 - c.749) , a Greek Father and theologian who gave the Church a definitive heritage of the Greek Fathers' teaching. After a preliminary consideration of the meanings of "Heaven" and Paradise as a state or a place, a substantial part of this thesis is then given to a detailed treatment of the Greek Fathers' teaching on the tree of the knowledge of good and evil and the tree of life in Paradise. The questions of the indispensability of the tree of life to the final bliss of the saints, and the doubtful place of the tree of knowledge also receive attention. The meaning of the trees for St. John of Damascus is expounded in order to show his use of the ideas of Greek Fathers prior to him, for example, Gregory Naziazenus and Maximus the Confessor. After this, the questions of entry into Paradise and the Greek teaching of the intermediate state of the departed are raised. The descent of Christ to Hades precedes discussion of whether St. John of Damascus taught a doctrine of Purgatory or not. The practice of prayer for the departed is examined with respect to its effect on the intermediate state of the faithful departed. Lastly, this thesis explores the necessity of the resurrection for the final bliss of the faithful, and establishes the relevance of this teaching for modern thought on the preservation of integral personality. In conclusion, the writer suggests that St. John of Damascus bequeathed to the Church rich insights into the Greek Fathers' doctrine of Heaven.

- Description: A review of trout metabolism, ingested energetic pathways, essential dietary nutrient requirements and the effect of water temperature on trout physiology identified the need to determine the effect of elevated temperatures (>18oC) on the nutrient requirements of rainbow trout. This review led to the hypothesis that as the temperature exceeds the optimum the growth potential of trout decreases with a theoretical concomitant decrease in the protein requirement. However, the increased metabolic rates of the fish should be reflected by an increased demand for lipids. The experiments designed to test this hypothesis revealed that at temperatures in excess of 18 oC the protein requirement for small (4.5g) and larger (>25g) juvenile rainbow trout are 40 and 35% respectively. This represents a decrease of 10% for the small juveniles and no change for larger juveniles compared to their requirements at optimum temperatures. The lipid requirements for the small as well as the larger juveniles increased by approximately 5 percent, to between 20 and 23 percent, compared to the requirement at optimum temperatures. Consequently the hypothesis was accepted. A review of practical diet formulation is presented along with a description of the experiments conducted to test several "least cost" diets under South African conditions. Recommendations that winter and summer diets be formulated and that the trout producers manufacture their own feeds are made. The most appropriate diet formulated and tested effected a 21 to 29.9 percent saving compared to the currently available feeds in South Africa.

- Description: Since Truman Capote's In Cold Blood: A True Account of a Multiple Murder and its Consequences was published in 1965, there have been many attempts to define and explain the phenomenon of the "non-fiction novel" as a unified narrative genre. Some of these attempts have been highly theoretical and scholarly, but most have been rather loose definitions referring to an extremely wide range of diverse factual narratives. Over the years, so many different works have been called "non-fiction novels" that it now seems as if the notion of such a unified genre is questionable. Surely it is not generically useful to say that such functionally distinct works as Oscar Lewis's La Vida: A Puerto Rican Family in the Culture of Poverty (1967) and Hunter S. Thompson's Fear and Loathing in Las Vegas: A Savage Journey to the Heart ot the American Dream (1971) belong in the same narrative category. The purpose of this study is to show that many of the works routinely referred to as "non-fiction novels" perform fundamentally different narrative functions and do not belong together in a unified genre. Roman Jakobson's model of communication and his notion of the "dominant function" are used to identify three functional categories into which the narratives discussed in the study logically fall: first, there are predominantly sociological works in which the referential function is the most important element of the communication; second, there are predominantly journalistic works in which the opinions of the writer or emotive function constitute the central narrative concern; and thirdly, we have works performing a dominant novelistic or aesthetic function in the sense that the secondary meanings and themes implied are the most important elements communicated. The thesis follows the following structure. In the introductory chapter, a critique of some of the major generic theories of the "non-fiction novel" as unified genre is offered. The purpose here is not to caricature what are sometimes extremely sophisticated studies. (Indeed, in my own analysis of texts, I am often indebted to the critical insights of the scholars whose theories I question in the introduction.) My purpose is merely to show that the corpus of works each writer refers to can be divided more logically between different dominant narrative functions. The introduction ends with a more detailed explanation of the adaptation of Jakobson's notion of "the dominant" and how it relates to the functional categories identified. Chapter 2 offers analyses of a group of documentary narratives that perform a dominant sociological function but have often been referred to as "non-fiction novels." The chapter starts with an analysis of James Agee's Let Us Now Praise Famous Men (1941), a text widely regarded as the first real American example of the "genre." This is followed by an examination of the anthropological works of Oscar Lewis: Five Families: Mexican Case Studles in the Culture of Poverty (1959), The Children of Sanchez: Autobiography of a Mexican Family (1964), Pedro Martinez: A Mexican Peasant and his Family (1964) and La Vida: A Puerto Rican Family in the Culture of Poverty. I conclude the chapter with an analysis of the recent sociological works of Studs Terkel: Division Street: America (1968), Hard Times: An oral History of the Great Depression (1970) and Working: People talk about what they do all day and how they feel about what they do (1974). In Chapter 3, the notion of subjective participation journalism is explained. This is followed by an analysis of three of the most famous and creative of the works that fall into this functional category: Hunter S. Thompson's Hell's Angels: The Strange and Terrible Saga of an Outlaw Motorcycle Gang (1966), Michael Herr's Vietnam classic, Dispatches (1977), and Norman Mailer's account of a famous protest march, The Armies of the Night: History as a Novel, The Novel as History (1968). Chapter 4 offers a discussion of three works that perform a dominant novelistic function in the realistic tradition of Dostoevski's Crime and Punishment. All three are based on actual murder cases, but the facts of the stories are subordinated to the novelistic themes the author wishes to abstract. They are: Meyer Levin's Compulsion (1957), Mailer's The Executioner's Song (1979) and Capote's In Cold Blood. From this outline, it may appear as if the study is loaded in favour of the sociological works discussed in Chapter 2. This is intentional because, although many critics have referred to them as "non-fiction novels", very little systematic and detailed analysis of these works as a corpus has been forthcoming. This long chapter is an attempt to redress the balance.

- Description: The Olavi Mountain Land is a 10 000 km2 mineral province located at the eastern extremity of the exposed Northern Platform of the Damara Pan African orogenic belt. The Olavi Mountain Land is tbe most important mineral province on the Northern Platform. Exploitation of tbe Cu-Pb-Zn-V province has been on-going since the possession of the territory by the German colonial authority in 1890. Production has been mostly from four mines which in order of importance are Tsumeb, Kombat, Berg Aukas and Abeoab. A second mineral province on the Northern Platform located in the west is centred on Sesfontein where as yet only insignificant mineralization has been noted. Besides these localities, the Northern Platform is conspicuously devoid of notable mineralization. The aim of this thesis has been to document tbe Berg Aukas deposit, an important end-member type of mineralization in the Otavi Mountain Land. The basic premise bas been to show tbat the derivation and localization of the mineralization is a consequence of two broad controls which can be simply summarised as features of the basement and of the carbonate sequences. The geodynamic evolution of the Damara Belt commenced with intra-continental rifting approximately 900 Ma ago. Rift grabens trending north-east were filled by the Nosib Group which comprises mostly clastic lithologies but also some volcanics. The earliest and largest rift is referred to as the Northern Rift. Separation of the Congo, Kalahari, and proto-South American cratons resulted in rifting and rapid downwarping so that an encroaching sea and an Olavi Group carbonate shelf developed along the northern margin of the Northern Rift. Significantly, the carbonates only covered the Northern Rift in the area of the Otavi Mountain Land where a basinal dome, referred to as the Grootfontein Basement High, marked the basin edge. In the west, the carbonates covered the less important Sesfonfein Rift, and it is only in these two areas where Nosib sequences underlie the carbonate platform. Carbonate sedimentation was interrupted by a major period of crustal readjustment and the deposition of an extensive mixtite throughout the geosynclinal Swakop Trough and Northern Platform. This is referred to as the Chuos Formation and subdivides the Olavi Group into a lower Abenab and an upper Tsumeb Subgroup. Reversal of spreading led to plate collision and subduction of tbe Kalahari craton beneath the Congo craton. It was accompanied by orogenesis which resulted in F1 folding of the Northern Platform into a series of north-easterly trending intermontane basins into which a molasse sequence known as the Mulden Group was unconformably deposited. Following this major north-south deformation mild east-west compression initiated F2 folding and the formation of doubly plunging synclines. The Berg Aukas Syncline represents a primary depositional basin which was subsequently folded. The original basin was formed by late Nosib rifting wben spreading caused the Swakop geosynclinal Trough to form. Carbonates of the basal Berg Aukas Formation were deposited in a lagoonal setting typified by reef and fore-reef facies witb peri-platform conditions. Rapid subsidence caused these sediments to be overlain by deep water carbonates of the Gauss Formation. Two styles of mineralization known as the Tsumeb-type and Berg Aukas-type are stratigraphically, isotopically, and mineralogically distinct. The Tsumeb-type is a cupriferous variety of discordant bodies confined to the upper sequences beneath the Mulden unconformity. The Berg Aukas-type is a Zn-Pb variety confined to tbe basal unconformity. The Berg Aukas deposit comprises three ore bodies known as the Northern Ore Horizon, the Central Ore Body, and the Hanging Wall Ore Body. Sphalerite and galena constitute the bypogene ore. Willemite, smithsonite, cerussite, and descloizite are important supergene ores. A review of genetic models concludes that a magmatic origin initially proposed for tbe Tsumeb deposit is entirely rejected and a basin dewatering model in line with Mississippi Valley-type deposits is proposed. The syntectonic nature of mineralization at Berg Aukas and elsewhere in the Otavi Mountain Land indicates that orogenesis encouraged dewatering and leaching of metals from a broad mineralizing front along the margin of the Swakop Trough. These were transported by acidic saline brines which migrated along the clastic aquifers and structural conduits provided by the Northern Rift. Fluid inclusion studies indicate that the hydrothermal fluids at Berg Aukas were very saline (23% TDS) and were transported at temperatures ranging between 92° to 210°C. Hydrothermal fluids which mineralized Berg AukaS-type deposits migrated along the basal unconformity towards the basement high and were responsible for hydrothermally altering the basement granites and gabbros and the Nosib clastic rocks. Tsumeb-type deposits resulted by migration of fluids through the carbonate pile and along north-easterly trending basement geofractures. As a consequence of variation in transport, the Berg Aukas-type and Tsumeb-type fluids leached different sources and therefore derived mineralogically and isotopically seperable characteristics. The localization of the Berg Aukas ores was controlled by the carbonate stratigraphy and structure. Hydrothermal karsting and ore deposition took place on the contact between Massive Grey and Light Grey Dolostones which represents a permeability contrast. The movement of the hydrothermal fluids was controlled by north-south trending vertical fractures caused by F2 folding which resulted in a peric1inal structure. Hydrothermal karsting was accompanied by ca1citic, dolomitic and silicic alteration. The heated acidic fluids initiated solution collapse and a variety of breccia types. Supergene processes resulted in oxidation and upgrading of the ore. Vanadium derived indirectly from gabbros in the basement complex were transported as calcium metavanadate complexes and deposited on contact with the oxidizing base metal sulphides.

- Description: As part of a development programme in the Moretele II District, the Government of the Republic of Bophuthatswana, commissioned in 1983 the building of a dry system coal-fired power station. The lack of local surface water to cool the power station resulted in a decision to investigate the potential of the ground water resources. The resources will be required to supply an anticipated 30 year water demand. Because of the high capital investment and the importance of establishing an accurate assessement of the ground water potential there was a need for a comprehensive and detailed hydrogeological study. The specific aim of the investigation is to assess and quantify the long term reliability of the ground water resources. The very limited data for the area necessitated a particularly thorough and detailed investigation. This thesis describes the hydrogeological investigation carried out to define the ground water resource potential of this area. The main objectives of the study are to identify, recognize and evaluate the hydrogeological processes operating on this previously ill-defined Karoo aquifer. To achieve the research objectives the hydrogeological investigation was formulated to make use of various traditional geological, hydrogeological, geophysical and hydrochemical techniques in a logical framework. More specifically, the work involved a hydrocensus, a geophysical survey, the drilling of exploratory boreholes, aquifer tests to determine the intrinsic hydraulic parameters, water level measurements and the collection and analysis of water samples. The combined results of these various techniques provided data to quantify, evaluate and then propose management strategies for the identified resources. The study provided an understanding of the local hydrogeological conditions and has allowed for a conceptual model of the aquifer system to be derived

- Description: A poorly consolidated concept base creates considerable difficulty amongst adolescents when it comes to the higher order task of analyzing complex, abstract and scientific weather phenomena as they appear on synoptic charts. The nature of the difficulties which they experience tends to encourage them to resort to the rote memorisation of concepts rather than understanding them. Kuhn (1962) avers that concepts, not enquiry methods, are at the core of rational thought. A well taught concept becomes a well developed mental construct which encourages understanding. It is the author's firm belief that in order for pupils to come to a thorough understanding of senior secondary meteorology - climatology and the synoptic chart, teaching of basic concepts should be graded and sequential. This thesis attempts to show the difficulties inherent in synoptic climatology. It relates these difficulties to adolescent cognitive development. Within this framework, the syllabus and past examinations of the Cape Education Department, and textbooks are examined. Teachers' views and pupils' understanding are gauged through the analyses of questionnaires and worksheets respectively. Conclusions are drawn and the problems which teachers and pupils encounter are addressed.

- Description: The ‘mfecane’ is a characteristic product of South African liberal history used by the apartheid state to legitimate South Africa's racially unequal land division. Some astonishingly selective use or actual invention of evidence produced the myth of an internally-induced process of black-on-black destruction centring on Shaka's Zulu. A re-examination of the ‘battles’ of Dithakong and Mbolompo suggests very different conclusions and enables us to decipher the motives of subsequent historiographical amnesias. After about 1810 the black peoples of southern Africa were caught between intensifying and converging imperialistic thrusts: one to supply the Cape Colony with labour; another, at Delagoa Bay, to supply slaves particularly to the Brazilian sugar plantations. The flight of the Ngwane from the Mzinyathi inland to the Caledon was, it is argued, a response to slaving. But they ran directly into the colonial raiding-grounds north of the Orange. The (missionary-led) raid on the still unidentified ‘Mantatees’ (not a reference to MaNtatisi) at Dithakong in 1823 was one of innumerable Griqua raids for slaves to counter an acute shortage of labour among Cape settlers after the British expansionist wars of 1811–20. Similar Griqua raids forced the Ngwane south from the Caledon into the Transkei. Here, at Mbolompo in 1828, the Ngwane were attacked yet again, this time by a British army seeking ‘free’ labour after the reorganisation of the Cape's labour-procurement system in July 1828. The British claim that they were parrying a Zulu invasion is exposed as propaganda, and the connexions between the campaign and the white-instigated murder of Shaka are shown. In short, African societies did not generate the regional violence on their own. Rather, caught within the European net, they were transformed over a lengthy period in reaction to the attentions of external plunderers. The core misrepresentations of ‘the mfecane’ are thereby revealed; the term, and the concept, should be abandoned.

- Description: Pupils entering High School for the first time experience many problems of orientation and adjustment. This study arose from the conviction that something could be done to alleviate this time of stress to the benefit of both pupil and school alike. A brief review of literature showed that despite a fair amount of research having been done in Britain and the United States, there is still a dearth of information relating directly to the South African situation. Most transition studies differentiate between factors affecting academic adjustment, those relating to personal adjustment after transfer, and those which involve adjustment to environmental factors. In general studies approached orientation pogrammes from two perspectives - those that handled orientation as an event with its concomitant administrative and practical advantages, and those that saw it to be a process which has more person-focussed advantages. Most researchers agree that each school has its own needs and that the orientation programme should reflect those needs. Many favour a problem-solving approach to the design of any programme and emphasize the need for constant evaluation of the programme to maintain relevance and effectiveness. A low-key investigation into adjustment problems faced by new pupils in the High School was conducted by means of a questionnaire. Three main areas of information were investigated: attitude to school; personal adjustment as indicated by the self-concept; and general impression of Secondary School. The results confirmed that problems of orientation and adjustment are experienced by pupils in the South African Education System and revealed a framework upon which an orientation programme could be based. An overview of existing orientation programme objectives stresses the fact that orientation must be concerned with the total adjustment of the child - personal, academic and environmental - and that, of necessity, it involves the whole family. An orientation programme is outlined and expanded upon in order to provide a framework upon which other programmes could be designed, specific to the particular needs of the schools involved. Finally, certain observations are offered which may lead to a better understanding of the demands of the orientation process

The petrology, mineralogy and geochemistry of the main zone of the Bushveld Complex at Rustenburg Platinum Mines, Union Section

- Description: Union Section of Rustenburg Patinum Mines is situated in the northwestern part of the Bushveld Complex, some twenty kilometres north of the Pilanesberg Alkaline Complex. The mining lease area covers a roughly triangular segment of Lower, Critical and Main Zone rocks, transgressed to the north and south by magnetite-bearing ferrogabbro of the Upper Zone. The Main Zone at Union Section is the focus of this study. The prime source of sample material for the study is the deep exploration borehole SK2, but additional, supplementary samples were collected on surface and underground, as well as from a second surface exploration borehole, SK4. In line with the recommendations of SACS (1980), the top of the Critical Zone, and therefore the base of the Main Zone, is taken to be the top of the Bastard Cyclic Unit. Sharpe (1985) suggested that the succession from the base of the Main is an isotopically separate entity Zone up to the Pyroxenite Marker from the rest of the Bushveld layered succession. This is not strictly true, as there is evidence that more than one parental magma was involved in the formation of this interval. It is, however, true that there are fundamental differences, particularly in isotopic makeup, between the Main Zone rocks below the pyroxenite Marker and those above (the latter having been assigned by Molyneux (1970) to subzone C of the Main Zone). Kruger et al. (1986, in press) suggested that the Pyroxenite Marker marks the base of the Upper Zone, and this convention is adhered to here. The implication of this is that the rocks which formerly constituted subzone C of the Main Zone are now considered part of the Upper Zone. The Main Zone rocks below the pyroxenite Marker were originally subdivided by Molyneux (1970) into two subzones, A and B. The results of the present study indicate that this subdivision is not justified. Instead, eight units have been distinguished in the Main Zone on geochemical, petrological and mineralogical bases. Each of these units is characterized by a coherent set, or progression, of chemical and petrological characteristics. The specific assignment of genetic connotations to these units has been deliberately avoided , at least until further studies of the Main Zone prove this to be justified. The demarcation of the eight units is illustrated in the composite diagram (Fig. 34) in the back pocket of this work, and the reasons for the subdivisions are listed in Table 6 (at the end of chapter 7 of this thesis). Until the late 1970's, it was thought that most layered cumulates formed by crystal settling (Wager and Brown, 1968). More recently, there has been a fundamental conceptual change, and many workers now believe that most cumulate rocks formed by in situ crystallization at the floor and walls of the magma chamber (McBirney and Noyes, 1979, Irvine, 1980a; Campbell, 1987). There is, however, some evidence for the physical separation of phases undergoing cotectic crystallization, particularly in the Upper Critical Zone and lower part of the Main Zone (Eales et al., 1986). This process, which has been alluded to in the past by various authors (Ferguson and Botha, 1963; Vermaak, 1976) involves the flotation of early-formed plagioclase crystals due to their positive bouyancy in tholeiitic liquids. The result is an apparent decoupling of the chemistry of pyroxene and plagioclase, as in unit IV of the Main Zone, where plagioclase becomes more anorthitic upwards, whilst pyroxene becomes more iron-rich. There is some substantial evidence, particularly in reversals in the strontium isotope initial ratio and the orthopyroxene Mg/(Mg+Fe) ratio , for multiple intrusion in the Main Zone. Although the largest and most important magma influx in the Main Zone was a high-R₀ aluminous tholeiite, as suggested by Sharpe (1985), the intrusive history of the Main Zone is believed to be far more complex than Sharpe (op. cit.) suggested. Significantly, there is strong evidence for small influxes of Upper Zone-type (Fe-rich tholeiite) magma in the upper reaches of the Main Zone. These are believed to be precursors to the major influx of Upper Zone-type magma at the pyroxenite Marker (Kruger et al, 1986, in press). The fate of intercumulus liquids in cumulate rocks has recently recieved substantial attention (Sparks et al., 1985; Morse, 1986; Barnes, 1986: Campbell, 1987). It is believed that the migration, or at least redistribution, of intercumulus liquids has played a vital role in modifying fractionation trends in the Main Zone. More importantly, the accumulation of late-stage intercumulus liquids is believed to be responsible for the formation of the Fe-rich ultramafic pegmatite bodies that interrupt the layered cumulates in borehole SK2 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: The Political Department and the Indian Political Service stand accused of sins of omission and commission. The evidence suggests that they were badly hampered by ill-conceived training prodecures, a lack of manpower and above all the incoherent policy of the British government towards the Indian states. The failure of the 1935 Federation Act which formally established the Political Department was not due to princely intransigence inspired by political officers. Between 1935 and 1947 the Political Department embarked on a vigorous programme of combining the resources of the smaller states to strengthen them as viable partners in a new India. Their lack of success in effecting the federation of the states with India in 1947 was not a result of the disinclination of political officers to implement reform as much as their inability to do so. Many princes were also unwilling to sacrifice a measure of sovereignty for efficient government and paramountcy precluded forcing internal reform on the princes. Paramountcy was never clearly defined and thus its retraction in 1947 took place amidst confusion and misunderstanding on all sides. The Indian Political Service was always treated as secondary to the Indian Civil Service and the states to British India. Britain's emphasis on constitutional change in British India, reflected in the Cripps Mission of 1942, the Cabinet Mission of 1946 and the rush towards independence in 1947 resulted in her inattention to the Political Department and the princes which culminated in the abandonment of both in 1947.

Between 1935 and 1947 the Political Department embarked on a vigorous programme of combining the resources of the smaller states to strengthen them as viable partners in a new India. Their lack of success in effecting the federation of the states with India in 1947 was not a result of the disinclination of political officers to implement reform as much as their inability to do so. Many princes were also unwilling to sacrifice a measure of sovereignty for efficient government and paramountcy precluded forcing internal reform on the princes. Paramountcy was never clearly defined and thus its retraction in 1947 took place amidst confusion and misunderstanding on all sides. The Indian Political Service was always treated as secondary to the Indian Civil Service and the states to British India. Britain's emphasis on constitutional change in British India, reflected in the Cripps Mission of 1942, the Cabinet Mission of 1946 and the rush towards independence in 1947 resulted in her inattention to the Political Department and the princes which culminated in the abandonment of both in 1947.

- Description: Chapter one suggests thet trade and merchant capital, which were crucial to Port Elizabeth's economic development during the nineteenth century, was subsumed by the rise of manufactures and industrial capital after the First World War. Industrial expansion was cut short by the post-war recession, which caused un- and underemployment. The black worker, who experienced a severe loss in real earnings on account of the increased cost of living, became involved in a struggle with employers for wage increases. Chapter two shows how the policy of segregation was applied in Port Elizabeth, which meant that the workers were subjected to an increasing degree of control and regulation of their daily lives. The conditions of reproduction in the black townships fostered inter-racial and cross-class mobilisation which culminated in the formation of a general labour union, the Port Elizabeth Industrial and Commercial Workers' Union (PEICWU). Chapter three will suggest links between the tradition in Port Elizabeth of worker resistance and the unionisation of black workers in the post-war period. Thus, the first three chapters attempt to provide a historical perspective for analysing the underlying causes of the 1920 Port Elizabeth disturbances. The immediate cause of the disturbances was the arrest of the Union leader, Masabalala, after he called for a general strike. Chapter four will show how the intervention of the local authorities provoked a spontaneous act of defiance on the part of Union members. A demonstration outside the Baakens Street Police Station to demand the release of Masabalala, precipitated the tragic shootings of 23 October 1920. The repressive violence which left 22 dead (with two further deaths resulting indirectly from the incident) was unprecedented in South African history. The resolution of the crisis brought the workers no nearer to obtaining a reasonable settlement of the wage issue. If anything, the resolve of employers to deny wage demands was hardened by the actions of the local authorities, who attributed the disturbances to ' agitation '. Such thinly-disguised justifications of the shootings by the dominant classes, however, provoked recriminations from other quarters. Chapter five examines the legal and political ramifications of the Port Elizabeth shootings. The circumstances of the shootings prompted the Smuts Government to appoint a Commission of Enquiry in the face of public pressure. The Commission found that the Police and vigilantes were largely to blame for the high death toll. But the Government's 'whitewash' of the findings could not absolve the Police from culpability entirely, nor could it sidestep its own responsibility and liability to victims of the shootings. Finally, in Chapter six, an attempt will be made to assess the long term impact of the shootings on the PElCU and the black labour movement in Port Elizabeth generally. The outcome of the episode was a victory for employers, which dealt a body blow to worker organisation which only became resurgent in the 1950s.

The presented case study aims to demonstrate the efficacy of psychotherapy with a child previously treated with medication

- Description: The impetus for using the therapy with J.B. for this study was primarily the challenge inherent in the situation from the moment the parents and J.B. arrived for their family interview and assessment. They had been through many professionals by then, and much medication. They were sceptical of our intervention, since nothing to date had relieved the situation, and J.B. still had outbursts of rage towards his mother, he was still expressing suicidal ideation and anxiety. The challenge was particularly in relation to the mother, who had great difficulty conceptualising J.B. 's problems as being emotional and relational in nature - she was infinitely more comfortable with physiological interpretations of everything. This had the effect on the therapist and the supervisor of frequently reassuring their belief in psychotherapy as the treatment of choice in this case, or if in fact there was a lurking 'disease ' or organic cause to the child's behaviour. The pressure was thus considerable in this respect, despite the fact that the child had been examined physically and nothing found. This study aims to demonstrate the efficacy of psychotherapy, and the changes that took place, with this patient who was previously treated with medication.

The promotion of a racially integrated Catholic community at King William's Town : challenges and opportunities

- Description: Taking as its point of departure the model of the Church as a sacrament of unity, this study explores its implications for the fostering of a racially integrated Catholic community within an apartheid society. The particular context within which the investigation is conducted is the Sacred Heart Church, King William's Town, where the writer is pastor to a multiracial congregation. A dialogical approach is adopted between theology and praxis, in terms of which the data from a social analysis of the community are brought into a creative dialogue with the Vatican II vision of the Church. Findings from the analysis show that the attitudes of congregants to a racially integrated community are generally ambivalent. Historical, theological, psychosocial and political factors are seen to play an important role in shaping these attitudes. Arising from the dialogue between theology and praxis, the model of a pilgrim Church suggests itself as more relevant and realistic. This model constitutes a proximate goal. The sacrament model of the Church provides direction and focus for the pilgrim Church and is viewed as the ultimate goal. These models must be seen as complementary. The study concludes with a pastoral plan aimed at attaining the goals described. The main thrust of this plan is directed at changing congregants' attitudes to a racially integrated community. The strategies suggested involve the motivation of congregants to become actively involved, the transformation of congregants' attitudes, the promotion of a positive attitude to conflict and the challenging of apartheid structures. A differential approach is suggested in the pursuit of these objectives. A final conclusion to be drawn from this study is that the search for community is never-ending and that the fostering of a racially integrated Catholic community is a slow and painful process.

The psychological experience of being in hiding against the background of political repression in South Africa during the 1986 general State of Emergency: a phenomenological explication

- Description: This is a study in Critical Psychology which examines the psychological costs of one of the direct outcomes of political repression - the experience of being in hiding. The aims of the study can be depicted on two levels: it is first and foremost an attempt to provide a true account of the phenomenon of being in hiding. On a second level of equal importance it is an implicit and overt critique of the social order in which this phenomenon takes place. The psychological experience of being in hiding is examined and discussed in its proper socio-political context. Therefore, the theoretical part of the mini-thesis has a strong political bearing, focusing on the State, and extra-parliamentary opposition in South Africa. repression The empirical part of the mini-thesis explicates the psychological experience of being in hiding with the aid of the phenomenological method of investigation. Due to the lack of research on this or similar topics, it is discussed within the framework of the experience of a stressful life event. For the five subjects being in hiding was an extreme intervention which was imposed upon their existences and which brought about a qualitative transformation in the individual subjects mode of being-in-the-world - not only in terms of practicalities, but also on a deep experiential level. It was a phenomenon which touched on fundamental parts of their experience of themselves and their individual worlds and the way in which they actualized themselves. For them it essentially entailed a loss of relationships and roles which resulted in an experience of a measure of encapsulation or separation from the world of others . It was a profound, multi - dimensional disruption of the structure of the subject ' s existence which infused a rich emotional experience .
