From Resumé: The effect of physico-chemical factors on the biology of the upper reaches of Swartvlei has been investigated during 1971-1972. Physico-chemical data have shown that Swartvlei was characterized by an extremely labile ectogenic meromixis. This instability was due to three factors : (1) the inflow of freshwater, (2) the inflow of sea water, and (3) wind stress. The magnitude of the effects of these factors upon the physics, chemistry and biology of the upper reaches was dependent upon whether or not the estuary mouth was open or closed. The phytoplankton of the pelagic zone of Swartvlei was dominated by nannoplankton. Three major categories were recorded: dinoflagellates, flagellates and diatoms. The major factor regulating their productivity in the upper reaches was light. As a result of humate staining and suspended detrital matter light conditions in Swartvlei were comparable to those in extremely eutrophic northern hemisphere lakes. A maximum integral primary productivity of 39.66 mg C m⁻² h⁻¹ was recorded in November 1972. The aerobic heterotrophic bacterial population in Swartvlei was usually less than 300 col. ml⁻¹ (plate counts). The activity of the total microbial population was measured with ¹⁴C techniques. Uptake of acetate was dominated by flagellates and one species of dinoflagellate when they were present. Glucose uptake was due to bacteria as was acetate uptake in the absence of heterotrophic phytoplankton. Glucose uptake was usually greatest in the anaerobic zone. This, and the presence of H₂S, suggested that a large active photosynthetic and chemosynthetic bacterial population may have been present in the monimolimnion. The possible importance of these bacterial processes in the total productivity of the pelagic zone of Swartvlei was discussed. Daytime zooplankton population size was statistically correlated with the size of the flagellate population. The zooplankton was dominated by Acartia and Halicyclops. These two animals were found in the anaerobic bottom of Swartvlei after October 1971. This corresponded to the disappearance of the flagellate population from the water column. The dominance of these animals in the zooplankton population may have been related to their ability to live in anaerobic water where the bacterial population appeared to be considerably more abundant than in the aerobic zone. Further implications of the results are discussed in reference to phytoplankton cell size and heterotrophy indicating a possible adaptive significance of these factors in Swartvlei.

This study explores a number of issues relating to the nature and scope of intangible heritage and critically examines some of its salient components in South Africa. It affirms that intangible heritage is socially constructed. Aspects of intangible heritage that seem inherited in the present are social constructs and products of social progression. They present the historical development of the practicing communities. Furthermore, this study affirms that all heritage is intangible. This is expounded in the study by exploring the history of the concept of intangible heritage over the decades which provide its evolution both at international and national levels, and within heritage institutions. Heritage cannot be understood and defined in terms of traditions, indigenousness, pre-colonialism, North and South dichotomies or Western and non-Western dichotomies. This definition would racialise and regionalise heritage, and politics of indigeneity would surface. The separation of tangible, intangible and natural heritage is an artificial demarcation that is for heritage management discourse.

From Introduction: 1. Background to the thesis: During the 1950' sand 1960' s it would appear that the explicit objectives of economic policy in South Africa were full employment and economic growth with some occasional emphasis on the pursuit of relative price stability. Other goals such as efficiency in resource allocation and the pursuit of an "acceptable" income distribution were at best implicit and subordinate to these objectives. This is exemplified by the fact that a number of key prices which were controlled by the authorities such as the exchange rate, interest rates and public utility tariffs were generally set at levels which were either over- or under-priced relative to factor scarcities throughout this period.

Domino Servite School (DSS) is a private school, founded in 1986, and situated on KwaSizabantu (KSB) mission station in the Natal midlands. This research into DSS is a case study which aims to present an illuminative evaluation in the Whole School genre, within that branch of educational research concerned with effective schools. The project aimed to make use of a compatibility paradigm accommodating nomothetic and anthropological data. In attempting triangulation of methodological approaches, it tried to establish the extent to which DSS may be considered an efficient and effective 'New Private' school. It also aimed to understand the school's raison d'ětre. In order to illuminate the relevance and social processes of DSS, evaluation made use of internal and external referents. The internal investigation sought to make judgements in reference to the efficiency of the school as an organisation. On the macro-level, whole school evaluation required extensive curriculum evaluation. On the micro-level, appraisal of teaching and assessment of pupil performance was undertaken. This internal investigation required a critical analysis of the school's formal, informal and hidden curriculum. The external evaluation sought to make judgement in reference to the effectiveness of DSS. On the macro-level, this required evaluation of the findings of the internal investigation in terms of a broader South African context. Implications, for example of the school's 'private' status, and its 'Christian' curriculum in respect of multi-culturalism, education for nationhood , and ethnicity were examined. The analysis of these dimensions paid attention to the school's spatial context in terms of both its 'rural' and missionary setting. Here the focus was on the school's formal curriculum. Analysis of the inter-relational context paid attention to its informal curriculum or the way in which the school deals with the commonality and diversity of its clientele and staff. The inter-relational context of the school examined the hidden curriculum, or the relationship between the school and the broader South African Community. A critical ethnographic account of this institution was therefore possible because of the dual focus on the internal and external evaluation reference points. Internal evaluation made extensive use of direct (non-participant) observation, structured and nonstructured interviews, questionnaires, and documentary analysis. Indirect (participant) observation, in particular Clinical Supervision (CS), was also used. Indirect (non-participant) observation made extensive use of Flanders' Interaction Analysis Categories (FIAC). Teacher self-evaluation was also included, while analysis of pupil performance made use of 'standardised' achievement testing and a tracer study. External evaluation required detailed study of local and international literature on issues relating to private schooling, rural and multi-cultural education, education for nationhood and ethnicity. The research found that much of the school's curriculum path is incongruous with its rural context largely because of its association with the former Department of Education and Training (DET), and because of its missionary heritage. As such the school is presently (1) located within a questionable (formal) curriculum tradition which has little relevance to, nor potential for, the transformational needs of either rural Natal or South Africa in general. However, this does not preclude the possibility of the school making a contribution to education for development in South Africa. (2) The school advocates a mono-cultural Christian value system and modified cultural pluralism which attempts to assimilate pupils from diverse socio-economic and ideologically homogeneous backgrounds. Multi-cultural education, plural values, religious and values democracy are therefore not part of the school's raison d'ětre. (3) The school, through its associated organisation Christians for Truth (CFT), represents a social view espousing either a modified cultural pluralism or multi-nationalism which allows for allegiance to a transcendent value system without compromising group. values and associations. This means that the school aims at assimilating or amalgamating diversity into a mono-cultural unity that transcends group identity. This transcendent culture is defined in Christian terms. The study recommends inter alia, further investigation into the educational implications of_values neutrality and the particularism of secular humanism; a comparative analysis of a random sample of private missionary schools and ordinary state controlled rural schools so that more generalisable results might be obtained; and a more thorough investigation into the parental and pupil contributions to the school, their attitudes and perspectives on missionary education and their feelings about the management styles evident in the organisation.

What role can the commercialisation of natural resource products play in the efforts to reduce poverty and vulnerability and how can this be enhanced? With poverty alleviation at the top of the global development agenda, this is a question posed by many scholars, practitioners, donor agencies and government departments operating at the environment-development interface. However, recent commentary on this issue is mixed and ambiguous, with some observers being quite optimistic regarding the potential of these products, while others hold a counter view. This thesis explores the livelihood contributions and poverty alleviation potential of four products traded locally in the Bushbuckridge municipality, South Africa; namely traditional brooms, reed mats, woodcraft and a beer made from the fruits of Sclerocarya birrea. A common approach, employing both quantitative and qualitative methods, was used to investigate the harvesting, processing and marketing arrangements, sustainability and livelihood contributions of each product. The results illustrate that any inference regarding the potential of the trade to alleviate poverty depends on how poverty is defined and interpreted, and on whether the role of these products is assessed from a holistic livelihood perspective that includes notions of vulnerability, alternatives and choice, diversification and the needs of rural producers themselves. Overall, the products studied were key in enhancing the livelihood security of the poorest members of society, forming an important safety net and assisting in raising household incomes to levels equivalent to the wider population, but generally were unlikely, on their own, to provide a route out of poverty. However, there were notable exceptions, with marked variation evident both within and across products. Incomes often surpassed local wage rates, and a minority of producers were obtaining returns equivalent to or greater than the official minimum wage. Other benefits, such as the opportunity to work from home or to diversify the livelihood portfolio, were also crucial, with the trade representing different livelihood strategies for different households. When viewed within the context of rising unemployment and HIV/AIDS these findings assume greater significance. While the trades were complex and growth limited, livelihood benefits could be improved on a sustainable basis if the sector was given the attention and support it deserves.

Text in Afrikaans / Hierdie navorsing is gerig op die vrylating van die gevangene en bet ten doel om aan die hand van 'n literatuurstudie, die Suid-Afrikaanse vrylatingstelsel binne die korrektiewe sisteem, histories met die nodige penologiese perspektief te beskryf. Aangesien bestaande Suid-Afrikaanse penologiese literatuur arm is aan inligting met betrekking tot die vrylating van die gevangene en meer spesifiek die vorme van vrylating, is verskeie bronne geidentifiseer ten einde historisiteit saam te vat en kontemporere beleid in die verband te bespreek. Alhoewel 1910 as vertrekpunt geneem is, is die fokus in die grootste mate geplaas op ontwikkeling sedert 1962. Bepaalde aksies deur onder andere die Inrigtingskomitee en Paroolraad kulmineer in die vrylating van die gevangene en om die rede bet die navorser ook die samestelling, bevoegdhede en werksaamhede van vermelde liggame nagevors en beskryf. / This research is aimed at the release of the prisoner and the objective is to historically elucidate the release system within the South African correctional system on the basis of a literature study, with the necessary penological perspective. Considering the fact that the existing literature on penology has hardly any information regarding the release of the prisoner and more specifically the different types of release, various sources have been identified in order to condense the historical information and to discuss contemporary policy in this regard. Although 1910 was taken as the starting point, the focus has largely been placed on development since 1962. Specific actions by, inter alia, the Institutional Committee and the Parole Board culminate in the release of the prisoner and for this reason the compilation, the competencies and the activities of the mentioned bodies were also described by the researcher. / M.A. (Penologie) / Sociology

The purpose of this study is to access the viability of traditional African courts in a future legal dispensation in South Africa. The research method used is a study of literature, court decisions and relevant statutes. The development of indigenous courts in South Africa is broadly outlined. As an analogy to the South African court system, the courts of Lesotho, Swaziland and Botswana are used to illustrate the dual systems of courts. Rapid urbanisation is discussed to illustrate that despite the increasing urbanisation, traditional values remain inherent to South African Blacks. The salient features of indigenous courts are analysed to facilitate the development of reform measures that have to be implemented so that the courts can meet the challenge of the future. / Constitutional, International and Indigenous Law / LL.M.

Modern trade marks perform multiple functions taken up in a functional matrix. Amongst them the distinguishing function is invariable whilst the other functions are variable. A legal-historical and comparative investigation of the law of trade marks in the United Kingdom, the European Union, the U.S.A. and South Africa reveals that only certain trade mark functions have traditionally been afforded protection under law. This is mainly because of a historical resistance to accepting trade marks as property in the Anglo and American trade mark systems and the primacy of origin theory in the European Community trade mark system. The bedrock of South African trade mark law has been the trade mark law of the United Kingdom. The restrictions brought about by common law property theory have been carried over into the South African law of trade marks. The South African law of property is however derived from the civil law and not the common law. The historical break in continuity of the common law trade mark tradition as a consequence of the interposition of the European Union and the reception of EC trade mark law in the United Kingdom affords the opportunity for a theory of trade mark rights to be established in South Africa which is derived from concepts already present in South African law. The thesis proposes that the legal right to the trade mark in South African law is an independent subjective right of the kind proposed by Joubert. The legal object of this right is the trade mark. The entitlements of use of the holder of the right are the functions which the holder is entitled to have the trade mark perform. A range of values in which the property in a trade mark is to be found are associated with the functions. Unlawful impingement upon any function infringes the trade mark right. This theory provides the Trade Marks Act, 1993 with a needed theoretical base. / Mercantile Law / LL.D.

Text in Afrikaans / In this thesis, the place and role of incorporeal things in the new South African law of things are examined. In the Roman law and Germanic customary law not only physical but also incorporeal objects, including rights, were regarded as things. In the early South African law of property (the period until 1950) a wide interpretation was given to the concept "thing". Consequently, things were said to denote either corporeal or incorporeal objects, as was the position in Roman and Roman-Dutch law. The recognition of incorporeal things suffered a setback during the fifties with the reception of the theories of the Pandectists in the South African law of things. The reception of the Pandectists theories can in all probability be attributed to writers such as WA Joubert and CG Van der Merwe. These writers gives preference to a narrow thing concept which only includes corporeal things and can be related to a certain interpretation of the doctrine of private law (subjective) rights which they adhere to. Incorporeal things are merely considered as exceptions. However, this narrow interpretation of things, are not generally accepted as correct. Several academics and the South African legal practice acknowledge a wider and more pragmatic concept of things which includes incorporeal things. Even before South Africa's new constitutional dispensation, pressure were exercised to extend the private law concept of things, despite the resistance of Joubert and Van der Merwe against the acknowledgement of incorporeal things. Creative legislation were introduced in 1971 which extended the concept of things by creating new land use rights. Within the context of the protection of land rights, a functional division of ownership is required in order to overcome the conflict between individual rights and public interests. The fragmentation of land rights provide the greatest possible number of people with the widest possible chance of access to land, and where necessary ad hoc legislation should be introduced to provide suitable security of tenure. Needs and problems regarding land reform were also addressed through legislation by recognizing different rights in land. By doing so, further pressure was placed on the narrow thing concept. Against this background, the Constitution of the Republic of South Africa 108 of 1996 started a new era for the South African private law. It is within this context that the relationship between private and public law comes to the fore. The Constitution offers the possibility of a wide interpretation of the public law concept of things. Our courts has already confirmed that the constitutional meaning of property is wider than the private law concept of property and that constitutional property is not limited to corporeal things. The application of the new constitutional dispensation on specific areas such as new property, labour related rights and intellectual property must be considered in light of the fact that the thing concept differs in the private law and public law. These constitutional developments can only sometimes be seen as an extension of the narrow thing concept. The implication is that incorporeal objects and rights can therefore be accommodated either within the existing private law paradigm, or within the wider constitutional paradigm. It is also argued that in certain circumstances ad hoc legislation should be introduced to provide the required security and protection. An analysis of the literature indicates that this is the preferable approach, rather than the dogmatic view that incorporeal things, in the form of other rights, are not considered as things. The new public law thing concept will have no influence on the further development of the private law in certain cases, but in combination with the existing theoretical and practical pressures to adopt a wider thing concept, the narrow private law approach could be given the final death-blow. / In hierdie verhandeling word die plek en rol van onstoflike sake binne die nuwe Suid-Afrikaanse sakereg ondersoek. In die Romeinse reg en Germaanse gemenereg is nie net stoflike nie maar ook onstoflike objekte, insluitende regte, as sake beskou. In die vroee Suid-Afrikaanse eiendomsreg (die tydperk tot 1950) is daar 'n wye interpretasie aan die begrip "saak" geheg. Daar is gevolglik verklaar dat sowel stoflike as onstoflike objekte sake is, soortgelyk aan die posisie in die Romeinse en Romeinse-Hollandse reg. Die erkenning van onstoflike sake het 'n terugslag beleef gedurende die vyftiger jare met die resepsie van die Pandektiste se teoriee in die Suid-Afrikaanse sakereg. Die resepsie van die Pandektisme kan waarskynlik toegeskryf word aan skrywers soos WA Joubert en CG Van der Merwe. Hierdie skrywers verkies 'n enger omskrywing van die saakbegrip wat slegs stoflike sake insluit, in navolging van 'n bepaalde interpretasie van die leerstuk van subjektiewe regte. Onstoflike sake word bloot as uitsonderings verklaar. Hierdie eng interpretasie wat aan die saakbegrip geheg word, word egter nie algemeen as korrek aanvaar nie. Verskeie akademici en die Suid-Afrikaanse regspraktyk erken 'n wyer en meer pragmatiese saakbegrip wat onstoflike sake insluit. Desondanks Joubert en Van der Merwe se weerstand teen die erkenning van onstoflike sake, is daar reeds voor Suid-Afrika se nuwe konstitusionele bedeling druk uitgeoefen om die privaatregtelike saakbegrip uit te brei. Kreatiewe wetgewing het in 1971 die lig gesien wat die privaatregtelik saakbegrip uitgebrei het deur die skepping van nuwe grondgebruiksregte. In die konteks van die beskerming van grondregte word 'n funksionele verdeling van eiendomsreg vereis ten einde die konflik tussen individuele regte en die openbare belang te oorkom. Die fragmentasie van grondregte bied aan die grootste moontlike aantal mense die wydste moontlike geleentheid om toegang tot grand te verkry. Behoeftes en probleme ten aansien van grondhervorming is oak by wyse van wetgewing aangespreek deur die erkenning van verskillende regte in grand. Sodoende is verdere druk op die eng saakbegrip geplaas. Teen hierdie agtergrond het die Grondwet van die Republiek van Suid-Afrika 108 van 1996 'n nuwe era in die Suid-Afrikaanse privaatregtelike sakereg ingelui. Binne hierdie konteks staan die verhouding tussen die privaat- en publiekregtelike saakbegrip op die voorgrond. Die Grondwet skep die moontlikheid om 'n wyer interpretasie aan die publiekregtelike saakbegrip te heg. Ons howe het reeds bevestig dat die konstitusionele betekenis van eiendom wyer is as die privaatregtelike eiendomskonsep en dat eiendom as 'n konstitusionele reg nie beperk word tot stoflike sake nie. Die nuwe konstitusionele bedeling se toepassing op spesifieke velde soos new property, arbeidsverwante regte en intellektuele goedereregte moet beoordeel word met inagneming van die feit dat die saakbegrip in die privaat- en publiekreg van mekaar verskil. Hierdie konstitusionele ontwikkelings kan soms as uitbreidings van die eng saakbegrip gesien word en soms nie. Die implikasie hiervan is dat onstoflike sake en regte of binne die bestaande privaatregparadigma of binne 'n wyer konstitusionele paradigma verklaar kan word. Daarword ook geargumenteer dat ad hoc wetgewing in sekere gevalle uitgevaardig moet word ten einde die nodige sekerheid en beskerming te verleen. 'n Analise van die literatuur dui daarop dat hierdie 'n lofwaardige benadering is, wat verkies moet word bo die dogmatiese siening dat onstoflike sake, in die gedaante van ander regte, nie as sake beskou kan word nie. In sommige gevalle sal die nuwe publiekregtelike saakbegrip geen invloed op die verdere ontwikkeling van die privaatreg uitoefen nie, maar in kombinasie met die reeds bestaande teoretiese en praktiese druk om 'n wyer saakbegrip te aanvaar kan dit die eng privaatregtelike benadering 'n finale nekslag toedien. / Private Law / LL.D.

The editor, J.M.H. Viljoen, himself a formally trained historian, purposefully promoted historiography, which he published in Die Huisgenoot. This dissertation is however, primarily concerned with the contributions of formally trained historians. Consequently many contributions by amateur historians were not considered. Historiography relating to specific periods and subjects is discussed and evaluated. In particular book reviews which were an outstanding feature of this historiography, are evaluated thoroughly. Similarly, letters of reaction to specific articles were also evaluated. In conclusion, it is evident that Die Huiagenoot which was published in the years 1923 - 1949, qualifies as an histori- cally-scientific periodical. / History / M.A. (History)
