- Description: The thesis presents ethnographic data and musical analysis (in the form of transcriptions) of Haul music which is the music style performed by Bedouin societies in Trab el Bidan region (Mauritania, Western Sahara, northern Mali, southern Algeria and northern Morocco). It is based on field research undertaken in Algeria in 2004-05 in the refugee camps of Tindouf, Algeria, where Saharaui people (a Bedouin society)live in exile. This research is unique and original as Haul has not, until now, been explored in depth by any scholar. My research on Haul reveals that the changes in Saharaui music in the refugee camps of Tindouf reflect changes in the musical traditions of Bedouin societies as whole; changes that can be traced to the revolution which occurred in Western Sahara in 1975, and changes that are a result of the migrations and life in exile that followed. I argue that these changes occurred due to the transnational experiences undergone by Saharaui people in their forced exile (caused by the Moroccan state) from their homeland in Western Sahara to Algeria. Further, I assert that the invocation of memory in Bedouin musical styles is evidence of past musical practices being retained in contemporary Haul performance, although other musical changes are similarly in progress.

This study also highlights the need for Eskom management to take into cognisance the unique rural prepaid customer service needs and how to meet them, perhaps a differentiated service approach rather than a one-strategy-fits-all approach. This is in view of gaps created between expectations and perceptions of service, especially in the reliability dimension that could require a concentrated or changed performance approach to close them.

- Description: Cocoyam [Colocasia esculenta (L.) Schott] is widely cultivated as a staple food in the tropical and subtropical regions of the world. The crop, however, remains unpopular and not well known outside KwaZulu-Natal Province of South Africa where it is cultivated mainly for subsistence. The aims of the study were to collect local landraces (accessions) of the crop from where it is found growing within the country for various studies and also to document its nutritional values as well as the safety/toxicity of the crop. The study was carried out using various methods. These included a comparative assessment of the proximate, mineral and antinutrient compositions of cooked and uncooked tubers of a typical commercially available cocoyam and potato found in South African markets. These investigations were repeated for the tubers and leaves of available landraces (seven accessions) of C. esculenta found growing in the farmers’ fields in KwaZulu-Natal Province. Also, an in vivo toxicological study on cooked accessions of the local landraces was conducted to determine possible toxicity effects after consumption using albino rats as a model. The results revealed that commercially available cocoyam and potato tubers have very close nutritional components. Analysis of the proximate composition of seven accessions (UFCe1- UFCe7) of cooked and uncooked tubers of cocoyam indicated that UFCe7 was better in ash, crude protein, crude fibre and crude lipid contents but with higher moisture which could make it more vulnerable to microbial attack. No tubers of the seven accessions appeared to be ii outstandingly better than the others based on their mineral compositions. However, in terms of antinutritional factors, UFCe1, UFCe3 and UFCe7 had the least amounts of oxalate, tannins and phytate in their cooked states. It was discovered however, that the leaves of the accessions of this vegetable contain substantial amount of minerals, and therefore, can contribute significantly to the nutrient requirements of humans and could be recommended as a cheap source of nutrients in South Africa. None of the accessions was outstandingly better than the others in terms of their mineral contents and anti-nutritional factors. Moreover, the current study has shown that boiling the leaves of cocoyam prior to consumption is an effective way of reducing the antinutrient contents of the leaves of the plant thereby making it safe for consumption. The findings also revealed that cooking C. esculenta leaves may increase the levels of protein, fibre and lipid contents while cooking may also decrease the mineral, carbohydrate and caloric contents of the leaves of the accessions. The leafy vegetable may, therefore, be recommended as a cheap source of plant protein. Cooking improved the nutritive value as a result of the reduction in antinutrient levels, thereby improving the food quality in all the tuber and leaf samples used for this study. At the same time, cooked samples also suffered loss of some nutrients with respect to the proximate and mineral compositions. However, supplementation from other food sources that are rich in these nutrients is necessary when these crops are cooked for consumption. Any of the cocoyam accessions may be recommended for consumption for improved protein and mineral nutrients while tubers of accession UFCe7 have also shown good promise in terms of protein and fibre content availability. The results of the in vivo study, using the liver and kidney functional endpoints of weanling albino rats (Rattus norvegicus) maintained on different accessions of cooked cocoyam-based iii diets (UFCe1-UFCe7) for 28 days, revealed that all the accessions produced selective alterations on the hepatorenal indices of weanling rats. The highest alterations were produced by UFCe4 while the least was from UFCe2. These alterations may have consequential effects on the normal functioning of the liver and kidney of the animals. The UFCe2 exhibited the least toxicity risk among the accessions of C. esculenta growing in KwaZulu-Natal Province of South Africa.

- Description: The aim of this research was to better understand teacher's beliefs about visual literacy and to explore how their beliefs influence their teaching practice. In order to investigate this, a case study was conducted that comprised of lesson observations and semi-structured interviews with two secondary school English home language educators. The backdrop to the research was the implementation of the new national curriculum for grade 10. The participants, though well educated and experienced teachers, felt their training had been inadequate in the area of teaching visual literacy and although they acknowledged the importance of visual literacy, it seemed to have a fairly low priority in their actual teaching practice. In particular, very little attention was given to the production of multimodal texts by learners. The reason for this low priority may be related to the requirements of the formal assessment programme as well as limited lesson time in which to cover an extensive curriculum. The research findings would seem to suggest a need for in-service training in this area as well as access to suitable learning support materials and teacher resources.

- Description: The community structure and predation impact of carnivorous macrozooplankton (>2 cm; chaetognaths, medusae, ctenophores and mysids), with particular emphasis on the chaetognaths Eukrohnia hamata and Sagitta gazellae, were investigated during three surveys conducted in late austral summer (April/May) of 2001, 2004 and 2005 in the Polar Frontal Zone in the vicinity of the Prince Edward Islands (46º45’S, 37º50’E), Southern Ocean. The 2001 survey formed part of the Marion Offshore Variability Ecosystem Study (MOVES II), while the 2004 and 2005 surveys formed part of the Dynamics of Eddy Impacts on Marion’s Ecosystem study (DEIMEC III and IV respectively). Macrozooplankton samples were collected using WP-2, RMT-8 and Bongo nets. Results of the hydrographic survey indicated that the region of investigation, the Polar Frontal Zone (PFZ), is an area of high mesoscale variability. During the 2004 survey the Antarctic Polar Front (APF) and the Subantarctic Front (SAF) merged to form an intense frontal feature with subsurface temperature and salinity ranging from 8.5-7.5ºC and 34.15-33.88, respectively. A cyclonic cold core eddy, believed to have been spawned from the APF, was observed during the 2005 survey. Macrozooplankton abundance and biomass ranged from 0 to 43.731 ind. m⁻³, and from 0 to 41.55 mg wwt m⁻³ respectively, during the three surveys. Among the carnivorous macrozooplankton, chaetognaths (Eukrohnia hamata and Sagitta gazellae) were most prominent, contributing up to 85% of the total biomass during all three surveys. Elevated biomass values were found near and within the frontal feature during the 2004 survey, and also along the eddy edge during the 2005 survey. However, hierarchical cluster analysis did not reveal the presence of distinct zooplankton groupings associated with the various water masses encountered during the surveys and this is probably due to the high mesoscale variability in oceanographic conditions that are characteristic of the PFZ. The total average predation impact of the selected carnivorous macrozooplankton during the 2001, 2004 and 2005 surveys accounted for 4.93 ± 6.76%, 0.55 ± 0.51% and 4.88 ± 4.45 of the mesozooplankton standing stock, respectively. S. gazellae had the highest consumption rate in all three surveys, consuming up to 800 g Dwt 1000m⁻³d⁻¹ during the study. Of the two chaetognaths, E. hamata dominated the chaetognath standing stock. The combined abundance and biomass values of E. hamata and S. gazellae ranged from 0 to 43.73 ind. m⁻³ and from 0 to 41.551 mg wwt m⁻³ respectively, during the three surveys. Inter-annual variability in the chaetognath densities was apparent. Highest abundances and biomasses tended to be associated with specific water masses, confirming the existence of a relationship between zooplankton community structure and hydrographic conditions. Generally, about 90% of the chaetognaths contained no food in their guts. S. gazellae consumed a wider variety of prey. Oil droplets occurred in the guts of ≈ 51% of E. hamata. Cannibalism was low in both species, but greater in S. gazellae than E. hamata. During the three surveys, the feeding rate values of E. hamata and S. gazellae went up to 0.48 and 2.099 prey d⁻¹ respectively. S. gazellae also had a greater predation impact on the mesozooplankton standing stock than E. hamata. The mean predation impact of the chaetognaths combined was 0.31 ± 0.291%, 0.52 ± 0.28% and 0.53 ± 0.56% of the mesozooplankton standing stock during the 2001, 2004 and 2005 surveys, respectively. During all three surveys, the majority of individuals (≈ 76%) of the chaetognaths were at stage I maturity, suggesting that during the time of study the chaetognaths were not reproducing. In both species a significant difference (log-linear analysis, p < 0.05) in maturities between the years investigated was observed. In general, there were no differences in lengths and maturities between the different water masses encountered during the surveys. The lengths of E. hamata and S. gazellae ranged from 5 to 24 mm and from 9.4 to 63.6 mm, respectively.

I was later introduced to a broader range of musics: blues, jazz, kwaito and traditional Southern African idioms. I found myself particularly attracted to the traditional music of the amaXhosa (especially that of the uhadi bow), possibly due to the fact that this music is hexatonic (that is, based on two major triads whose tonics are one tone apart), a system that bears certain resemblances to the Western tonal idiom. However, much of my musical experience tended to be entrenched in the piano and flute music I played: mostly works by composers who were neatly ensconced in the traditional Western canon. Therefore, despite the broad range of musics with which I was familiarisedduring my tertiary studies, I feel that this early experiential background is the reason I feel most comfortable with Western-influenced music. More recently, I discovered a whole new genre to explore: film music, particularly the work of Elliot Goldenthal, Danny Elfman, John Williams and Philip Glass, whose unique brand of minimalism has extended from the concert hall to thefilm theatre. I am fascinated by the ways in which film scores function. A "main titles" theme usually appears as the film opens, upon which most of the subsequent music is based. This is not a linear process, like a theme and its variations, but a lateral, where the main titles theme is the core that engenders other themes that all share a familial resemblance.

- Description: This study set out to examine whether the Eastern Cape Tourism Board (ECTB) had the capability to cope with change. The tourism industry is very dynamic and for the organization to survive, it must be able to adapt itself in a constantly changing environment. The research question was derived from a study done by Human and Horwitz (1992), in which they examined how South African companies cope with change. They developed a model and a questionnaire to measure the capabilities of coping with change. Their model and questionnaire were based on the following four dimensions: strategic orientation, control orientation, social focus and institutional focus. This model classified organizations into four types, namely: the Boardroom organization, the Technocracy organization, the Hardhat organization as well as the Missionary organization. These typologies are discussed in Chapter 2. A modified version of the Human and Horwitz questionnaire was used to conduct this research. The original questionnaire has 32 items, and the questionnaire used in this study has the same number of items. The modification was done to nine questions, to ensure that they were of specific relevance to the organization being researched. The questions were slightly modified taking care to ensure that they still fit within the original dimensions measured by Human and Horwitz (1992). The questionnaires were distributed within the organization, particularly to those employees in the Tourism section, as the organization also had a Conservation section. The Conservation section was excluded due to the fact that a policy decision had already been taken to separate the two sections, thereby creating two organizations. When the questionnaires were returned, they were analyzed using 'Statistica' , a computerized statistics program. The results showed that the ECTB does not have the capability to cope with change as it lacked the critical strategic orientation that Human and Horwitz (1992) suggest is a key requirement for coping. The profile of the organization showed that the ECTB could be classified as primarily being a Technocracy organization, and secondarily a 'Hardhat' organization. (See details in Chapter 4). Human and Horwitz (1992) suggest that an organization to be able to cope with change, must be a 'hybrid' of these four types. The implications of these results suggest that the organization is lacking in the dynamism brought about by having a strategic orientation. Human and Horwitz argue that the profile of an organization coping well with change should show a 'balance' in terms of orientation (strategic orientation and control orientation). The ECTB's profile does not show this balance, and can therefore be said not to have the capability to cope with change. The results of the profile are discussed in Chapter 4.

- Description: This study set out to examine whether the Eastern Cape Tourism Board (ECTB) had the capability to cope with change. The tourism industry is very dynamic and for the organization to survive, it must be able to adapt itself in a constantly changing environment. The research question was derived from a study done by Human and Horwitz (1992), in which they examined how South African companies cope with change. They developed a model and a questionnaire to measure the capabilities of coping with change. Their model and questionnaire were based on the following four dimensions: strategic orientation, control orientation, social focus and institutional focus. This model classified organizations into four types, namely: the Boardroom organization, the Technocracy organization, the Hardhat organization as well as the Missionary organization. These typologies are discussed in Chapter 2. A modified version of the Human and Horwitz questionnaire was used to conduct this research. The original questionnaire has 32 items, and the questionnaire used in this study has the same number of items. The modification was done to nine questions, to ensure that they were of specific relevance to the organization being researched. The questions were slightly modified taking care to ensure that they still fit within the original dimensions measured by Human and Horwitz (1992). The questionnaires were distributed within the organization, particularly to those employees in the Tourism section, as the organization also had a Conservation section. The Conservation section was excluded due to the fact that a policy decision had already been taken to separate the two sections, thereby creating two organizations. When the questionnaires were returned, they were analyzed using 'Statistica' , a computerized statistics program. The results showed that the ECTB does not have the capability to cope with change as it lacked the critical strategic orientation that Human and Horwitz (1992) suggest is a key requirement for coping. The profile of the organization showed that the ECTB could be classified as primarily being a Technocracy organization, and secondarily a 'Hardhat' organization. (See details in Chapter 4). Human and Horwitz (1992) suggest that an organization to be able to cope with change, must be a 'hybrid' of these four types. The implications of these results suggest that the organization is lacking in the dynamism brought about by having a strategic orientation. Human and Horwitz argue that the profile of an organization coping well with change should show a 'balance' in terms of orientation (strategic orientation and control orientation). The ECTB's profile does not show this balance, and can therefore be said not to have the capability to cope with change. The results of the profile are discussed in Chapter 4.

- Description: The research problem addressed in this study was to determine what the main factors are that contribute to the competitive advantage of the catalytic converter industry cluster in the Eastern Cape. To achieve this objective theoretical models of competitive advantage and literature of industry clustering were identified. For the models on competitive advantage, Porter’s diamond was used for national competitive advantage and Porter’s model on the competitive environment, which affects the competitive advantage of a region. Other theories on competitive advantage of cities and regions were identified, leading up to the theory on the cluster approach. The literature mentioned was broken down and analysed using literature, from knowledgeable people in the automotive industry in the Eastern Cape, identified during the study. A questionnaire was developed to test the degree to which the catalytic converter industry cluster in the Eastern Cape is in agreement with the literature study. The empirical study obtained a strong concurrence with the literature study on national competitive advantage and the theory of clusters. This resulted in a strategy for the catalytic converter industry cluster to sustain competitive advantage and remain globally competitive.

- Description: According to the WHO [2014], one in every 14 people is regular users of drugs, adding up to a total of 3.74 million people (taken as a percentage of the population as of 2013). While the United Nations Office on Drug Crimes (UNDOC) revealed that in 2015, 167,750 people have died due to direct use of drugs, the patterns of drug use have increased from 1.3% to 9.8% in 2018 (UNDOC, 2018:49-51). The Eastern Cape is one of the poorest provinces of South Africa characterized by a poor primary and secondary education system, a lack of basic facilities, and poor transport infrastructure. It is evident that South Africa in general, and the Eastern Cape in particular, is experiencing a major problem with drug and substance abuse, which is especially common in school-going children. Furthermore, the Eastern Cape have limited access to specialized drug rehabilitative services due to the geographical location of existing services and the cost associated with travelling. Rehabilitation centres are available in both the State-funded and privately-owned institutions, yet the researcher was perplexed as to why, despite the proven effectiveness of the rehabilitation program in the private health care facility, relapse of the drug abusers in the Eastern Cape continues to occur. This study aimed to explore and describe the reasons why adult drug abusers who previously completed a detoxification program at Clinic A in Buffalo City Municipality, relapse after discharge. Understanding the reasons or factors of relapse assisted in the formulation of recommendations to adjust the program and prevent or reduce relapses. In this study, a qualitative, descriptive, contextual and exploratory, qualitative research design was followed to gain insight into and understand the reasons that contributed to the relapse of the adult drug abuser in a private health care facility in the Eastern Cape. 9 The population was defined as the entire group of persons who met the inclusion criteria, who relapsed after successful completion of a drug detoxification program. The sample consisted of 25 relapsed persons who were willing to participate. In Phase 1 of the study, the researcher invited relapsed adult abusers who were readmitted for the detoxification program from January to December 2019 to participate in an individual interview. The data was then reduced into patterns, categories and themes by clustering and coding the data according to Tesch’s steps of analysis. In Phase 2 of the study, the researcher critically analysed the detoxification program currently used in the private health care facility. National and international articles and best-practice standards were also consulted. Finally, a literature control was done to place the findings of the study in the context of what was already known. In the phenomenology, the literature should be reviewed after data collection and analysis so that the information in the literature does not influence the researcher in any way. In phase 3 of the study, the researcher wrote recommendations to improve the detoxification program at Clinic A [BCM].

Such criteria may help teachers in selecting textbooks which have theoretically-informed reading programmes. It was first necessary, therefore, to isolate those points from reading comprehension theory that could be included in the criteria. Secondly, other checklists/criteria in ESL evaluation were examined to identify a framework within which to work. In the first draft, questions to be included in the criteria/checklist were formulated using justification from reading comprehension theory. A focus group technique was then used to obtain preliminary feedback on the usability of the checklist. Suggestions from the focus group were used to revise the cri teria . A final checklist was prepared which teachers could use as an instrument to evaluate reading comprehension programmes in language textbooks.

- Description: The transduction of stress signals in plants is known to involve complex hysiological responses. In D. salina a range of stresses results in hyperaccumulation of ft-carotene and an understanding of stress responses in this organism has important biotechnological implications. In this thesis an attempt was made to elucidate the physiological components involved and establish a role for pH in response to high light stress. In order to achieve this the effect of high light stress on photosynthesis and cell productivity was measured. Results showed that photosynthetic carbon assimilation, oxygen evolution and cellular productivity was initially inhibited by exposure to high light intensities, but this inhibition was transient and was overcome by a rapid increase in all three parameters. The response of the carbon pool intermediates was also investigated. It was shown that on exposure to high light ft-carotene declined but then showed a rapid increase after about 4 hours of exposure. It was also demonstrated that the initial loss of ft-carotene was due to loss of this pigment from the photosynthetic pigment bed and that the hyper-accumulation of ft-carotene was due to accumulation of ft-carotene in lipoidal globules located in the chloroplast stroma. It was further demonstrated that there was mass movement of carbon in the xanthophyll cycle shortly after exposure to high light. This was characterized by the de-epoxidation of violaxanthin to antheraxanthin with a further de-epoxidation to zeaxanthin, thereby decreasing the epoxidation state of the cycle. Furthermore, it was shown that there was relocation of carbon from violaxanthin to the plant growth regulator abscisic acid. It was also shown for the first time in D. salina that the production of ft-carotene and operation of the epoxidation state of the xanthophyll cycle has a periodicity which is established after exposure to successive cycles of a light regime. Chlorophyll fluorescence was used together with well established ammonia stress responses to acquire a general overview of energy dissipation from the photosynthetic pigment bed. In conjunction with an understanding of xanthophyll cycle operation during exposure to high light stress it has been possible to establish a relationship between chlorophyll florescence, xanthophyll cycle operation and intracellular pH. It was also shown using chlorophyll fluorescence that after 4 hour exposure to high light a maximum fluorescence peak could no longer be induced indicating a transition at about this point from a state of reversibility to commitment of the full stress response. Nuclear magnetic resonance was used to follow intracellular pH fluxes during exposure to high light. A novel technique was developed for studying photosynthetically active organisms in the dark using nuclear magnetic resonance. These results showed that on exposure to high light stress there is rapid acidification of the chloroplast stroma and to a lesser degree of the acidic vacuole. The pH of these compartments is re-established after about 4 hours which is co-incident with the onset of fl-carotene hyper-accumulation and the loss of the induction of the chlorophyll fluorescence peak indicating an intimate relationship for fl-carotene, chlorophyll fluorescence, xanthophyll cycle operation and pH. The results from this study allow for the proposal of a general physiological stress transduction response mechanism for D. salina which is common for a range of different stresses and where intracellular pH plays a central role.

Personality factors were analysed by means of Cattell's l6 Personality Factor Questionnaire, standardised for South Africa. Attitudes were determined by qualitative analysis of data from semi-structured interviews. Specific personality factors associated with positive and negative attitudes towards 'problem animals', including Lynx Felis caracal, eagles and vultures, were identified. Demographic and situational influences and certain world views associated with environmental attitudes are also discussed. Re-orientation of perspectives are recommended for farmers, conservationists and environmental educators.

- Description: The aim of this thesis is to reveal the intimate relationship between John Chrysostom's Eucharistic theology and the christian life, and that at the Eucharist Man's true being is demonstrated. It investigates Chrysostom's exegetical and oratorical method in order to ascertain how he approached a text and how he delivered his understanding of it. He is a representative of the Antiochene School of Exegesis and his fame as a preacher was a result not so much of his oratorical construction, but of the underlying spiritual unity within the oration. The purpose of all his preaching and exegesis was to evoke a moral response from his hearers. In the consecration of the elements, Chrysostcm displayed a remarkable openness to the varying traditions. He saw reciting the words of institution and invoking the Spirit as effecting consecration. Not only this, but also the moral life of the congregation played its part in effecting consecration. Once the elements had been consecrated, Christ was sacrificed, symbolically and literally, not again but in memory (Greek letters) of the Passion, which thereby becomes a present reality. In Chrysostom's understanding of the real presence he displays yet again an openness to the traditions. Christ is both present symbolically through the elements and literally through the transformation of the elements. The real presence demanded of the communicant a high degree of morality. To approach the Table on which Christ lay demanded a life of virtue, not only from the individual communicant but from the whole community. Those who partook unworthily imitated Judas and shared his fate. The community had to approach the Table in unity. At the Table, however, the community received its unity from Christ, the community became the body of Christ. Through participation and becoming the body of Christ, the community was united with the Godhead . Schism, therefore, was a very serious sin for it tore the body of Christ apart. For Chrysostom, Christ was also present in and intimately united with the poor. The church had to be able to be aware of Christ's presence in the poor and be responsible toward Him. In giving to the poor, the communiicant acknowledged that he/she had received at the Table and also received his/her salvation from Christ through the poor. The whole Eucharistic feast not only fed the christian with spiritual food, but called the communicant away from gross materialism to a life-giving dependance on God. It called the communicant to give to others as he/she had received from Christ.

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: The isolation and structure determination of dubiin and leonitin, two new diterpenoid acetates from Leonotis dubia and Leonotis leonitis respectively, are discussed. The compounds are diterpenoids of the labdane type and are closely related to marrubiin. The proposed structures are based on chemical and spectral evidence. Dubiin, C₂₂H₃₀0₆̕ contains a tertiary hydroxy- group, a furan ring and a ó-lactone while leonitin, C₂₂H₃₀0₇̕ is a γ - dilactone. at C-20. Both compounds are unusual in being oxygenated The extraction of three Euryops species and the isolation of euryopsol, C₂₂H₃₀0₄̕̕ are also described. A furanoeremophilane structure containing three hydroxy- groups, one of which is at a bridgehead position, is proposed. Euryopsol is the first furanoeremophilanoid with a substituent attached at C-IO

An analytical commentary on Act No 40 (Welfare Organisations Act) of 1947 and its relation to Act No 79 (National Welfare Act) of 1965

- Description: From Introduction: Act No. 40 of 1947, after nineteen years in operation has been superseded by Act No. 79 of 1965. Here an attempt will be made to establish first those conditions which, in the years preceding 1944, produced a demand, both from the general electorate, from members of the legislature and from those actively concerned with the problems of social welfare in South Africa, that appropriate legislation be promulgated to alleviate the conditions. As Act 40/1947 was drafted in an attempt to remedy antecedent conditions, so it is hoped to show that in its provisions, and their attempted execution by the organs established in terms of the Act, there may be discerned the germs of at least some of the provisions of Act 79/1965. Effects of past economic depressions as well as a more recent increased awareness of overseas conditions and thinking, coupled with the war-time atmosphere and the start of rapid industrialisation all .affected the legislation that was finally passed. The degree of unanimity amongst those who advocated control of Welfare bodies through legislation will be considered, as well as the adequacy of the means available for its enforcement. So, too, will habits of thought and action which both affected interpretation and limited co-operation on several levels, for they also are amongst the factors which, by limiting the Act's effectiveness, strengthened the demand for new legislation. Attention will also be paid to that reaction against things regarded as "foreign” which, always present in South Africa, gathered strength from the 1860's, gained expression in official quarters especially after 1948 and which, together with the policy of separate development, greatly affected activities in terms of Act 40/1947.

- Description: In my kennismaking met die poësie van Yeats en Roland Holst het ek onvermydelik opgemerk dat hulle sekere simbole ooreenkomstig gebruik, dat hulle dieselfde hoë, aristokratiese waardes handhaaf en gevolglik 'n afkeer het van die moderne massa-demokrasieë. Later het ek ontdek dat albei digters sterk in die Keltiese mites en sages belang gestel het en dat Roland Holst Yeats as 'n belangrike invloed eien. Dit alles, en die feit dat hulle albei enkele gegewens uit die Griekse mitologie daarby voeg in wat hulle "mites" word, het my voorgekom as goeie rede vir 'n vergelykende studie. So 'n ideë-studie het egter gedreig om iets heel anders te word as die literêre beskouing wat ek beoog het. Geleidelik het dit egter geblyk dat die mite méér moet wees dan die ideë-sisteem; en juis dit waardeur die mite meer is dan ideë-sisteem het die belangrikste regverdiging geword vir 'n vergelykende studie, en terselfdertyd, vir 'n toespitsing van die aandag op die poësie.
