Capitalism and natural rights: Marx, Locke and the moral justification of capitalism: inaugural lecture delivered at Rhodes University

- Description: Inaugural lecture delivered at Rhodes University , Rhodes University Libraries (Digitisation) , ONE of the commonplaces among political philosophers and theorists is the contempt with which Marx regarded Natural Rights theory. In 1843 he wrote that "the so-called rights of man, the droit de l'homme as distinct from the droit du citoyen, are nothing but the rights of a member of civil society, that is the rights of egoistic man, of man separated from other men and from the community." And again "the real man is recognised only in the shape of the egoistic individual, the true man is recognised only in the shape of the abstract citoyen."1 Marx saw Natural Rights as means for the justification of capitalism, and so, as justifying inequalities of wealth and property-ownership. And of course it is true that many writers, in supporting Natural Rights, have stressed, as Stuart Brown expresses it, that "They are the rights of a man to the protection of what is in his interest. The moral interests of one man may differ radically from those of another. Different men may have radically different needs and capacities. And these differences, in conjunction with unavoidable differences in opportunity, produce differences in estate. "2 Expressions of this kind make clear the point of Marx's critique. I wish tonight to argue and to attempt to establish two main theses. The first is that, despite Marx's expressed attitudes to Natural Rights, his own theory of capitalism cannot easily be disentangled from Natural Rights theory, and, if my argument is right, it in fact depends upon it. Secondly, I shall try to show, through an examination of the theories of John Locke, that if Natural Rights theory is to be taken seriously, it is at odds with the very capitalist theory which it is generally taken to support, and that Natural Rights cannot therefore provide an adequate under-pinning of capitalism, at least not without generating self-contradictions within the theory of Natural Rights. If the arguments which I shall present are right, I shall hope to have established what might be termed two paradoxes.

A comparison of the performance of selected conceptual models of the rainfall-runoff process in semi-arid catchments near Grahamstown

- Description: A comparison of the performance of selected conceptual models of the rainfall-runoff process forms the central theme of this study and the comparison was conducted with three major objectives in mind. The first objective was to develop a conceptual model that could be used by practising hydrologists for the refinement and extension of historical streamflow records. The major requirements of the model were that it should be simple in structure and easy to operate and yet be flexible in terms of complexity of structure and input requirements as well as producing output at a level of accuracy that is competitive with that of the more complex models presently available. A comparison of the performance of the required model with that of other models formed an integral part of the development process. The second objective of the comparative study was to contribute to current knowledge of the criteria used in the selection of a suitable model for a particular application. There are, at present, no reliable guidelines to assist the hydrologist in selecting a suitable model from the wide range of models available and a comparative study would indicate the merits of various forms of model structure. The third objective is associated with the problems that arise when no streamflow data are available for model calibration. One approach is to calibrate the model in a nearby gauged catchment that the hydrologist regards as being 'hydrologically similar' and transferring the model parameter values to the ungauged catchment. Little is known about the feasibility of this parameter transfer process or about the choice of a model for such an application. The third objective was to test the feasibility of the parameter transfer process and to make use of the comparison of model performance to determine the model characteristics that are most suitable for the purpose

- Description: The objective of the thesis is to make a critical assessment of the performance of three relatively simple deterministic models of the rainfall-runoff process. The need to evaluate and compare deterministic models arises because of the large number of models which are available in the literature. A number of the available models would appear to be equally suitable for a given situation whereas many models are found to be valid only under the specific range of conditions for which they were developed. Therefore there is a need for guidelines to allow the most judicious selection of a model for a particular set of circumstances. The models used in the study will be tested in a semi-arid catchment to determine their applicability under ephemeral flow conditions

However, the broad subject of compensation in terms of cost to the organisation may be examined in two sections, namely, wage and salary administration, and fringe benefit administration. The compensation survey forms an integral part of both administration processes, and thus becomes a necessary and essential device in the determination of the final compensation package to the employee.

A history of the growth and development of the Seventh-Day Adventist Church in Southern Africa, 1920-1960

- Description: From Introduction: The most natural divisions of time for this historical survey of the growth and development of the Seventh-day Adventist Church in Southern Africa fall into three periods: (1) from 1920, when the African Division of Seventh-day Adventists was organized, to 1931, when it was reorganized under the name Southern African Division; (2) from 1931 to 1945, covering the period years of the Great Depression and Second world War; (3) from 1946 to 1960, the post-war. Attention is given in Chapter I to a certain phase of church development because the church had emerged at the highest level of Adventist organization, i.e. a Division. Although the first group of Adventists adopted the simplest form of organization in 1892 known as the South African Conference, the church was small and little known. The church at Division level therefore embarked on a programme of orientation and adaptation to gain recognition and make itself known everywhere. Closely allied to this was organization. Chapter II defines the organization of the church and explains how it was financed. The history of its organization and reorganization is also traced. Chapters III and IV deal with an era of expansion during the twenties in the establishment of missions, medical missions and training institutions, while new mission fields were entered and old mission fields were further developed. Chapters V and VI continue to trace the development of missions, mission fields, medical missions, and training institutions together with important changes in the medical and educational work. Further reorganization and new developments in the European church and African church are also outlined. The great emphasis on expansion and the development of institutions finally reached a point whereby "institutionalism" overtook "evangelism". Chapter VII discusses this problem and what was done to try and arrest it. Thus the history of the church is brought to an interesting turning point and climax in Part Two. Chapter VIII breaks from the common run of growth and development in missions, medical missions and institutions and traces the development of the principles and practice of the Adventist Church. The Southern African Division set itself the objective of full maturity in the establishment of a self-supporting, self-governing and self- propagating church in Africa. The history of these principles are covered together with the principles governing the reception of government grants-in-aid. Chapter IX deals with the analysis and development of the three-fold ministry of teaching, preaching and healing. These chapters in Part Three do not constitute a conclusion but simply give further insights in the growth and development of the church .

- Description: From Introduction: The most natural divisions of time for this historical survey of the growth and development of the Seventh-day Adventist Church in Southern Africa fall into three periods: (1) from 1920, when the African Division of Seventh-day Adventists was organized, to 1931, when it was reorganized under the name Southern African Division; (2) from 1931 to 1945, covering the period years of the Great Depression and Second world War; (3) from 1946 to 1960, the post-war. Attention is given in Chapter I to a certain phase of church development because the church had emerged at the highest level of Adventist organization, i.e. a Division. Although the first group of Adventists adopted the simplest form of organization in 1892 known as the South African Conference, the church was small and little known. The church at Division level therefore embarked on a programme of orientation and adaptation to gain recognition and make itself known everywhere. Closely allied to this was organization. Chapter II defines the organization of the church and explains how it was financed. The history of its organization and reorganization is also traced. Chapters III and IV deal with an era of expansion during the twenties in the establishment of missions, medical missions and training institutions, while new mission fields were entered and old mission fields were further developed. Chapters V and VI continue to trace the development of missions, mission fields, medical missions, and training institutions together with important changes in the medical and educational work. Further reorganization and new developments in the European church and African church are also outlined. The great emphasis on expansion and the development of institutions finally reached a point whereby "institutionalism" overtook "evangelism". Chapter VII discusses this problem and what was done to try and arrest it. Thus the history of the church is brought to an interesting turning point and climax in Part Two. Chapter VIII breaks from the common run of growth and development in missions, medical missions and institutions and traces the development of the principles and practice of the Adventist Church. The Southern African Division set itself the objective of full maturity in the establishment of a self-supporting, self-governing and self- propagating church in Africa. The history of these principles are covered together with the principles governing the reception of government grants-in-aid. Chapter IX deals with the analysis and development of the three-fold ministry of teaching, preaching and healing. These chapters in Part Three do not constitute a conclusion but simply give further insights in the growth and development of the church .

- Description: Part I consists of a detailied review of the available literature on the Fe- Ti oxides and their solid solution relationships. Particular attention is glven to the microstructures exhibited by these oxides and the hypotheses put forward to explain them. These data are synthesised and models are presented in which the microstructural developments in titaniferous magnetites amd ilmenites are explained in terms of current ideas on the influence of oxygen fugacity, exsolution mechanisms and crystal chemistry. These models have direct application to the microintergrowths observed in the naturally occurring Fe-Ti oxides from a wide range of igneous rocks. The available data on the minor and trace element chemistry of the Fe-Ti oxides are reviewed with particular reference to their variation in these minerals from different host rocks. The behaviour of the Fe-Ti oxides during secondary oxidation is discussed with particular reference to the oxidation of titaniferous magnetite and the weathering of ilmenite. The results of a mineralogical investigation into the co-existing Fe-Ti oxides from a range of igneous rocks including kimberlites, gabbros, dolerites, diabases, syenites, granophyres, granites and pegmatites are presented in Part 2 together with data on the ilmenites present in certain Eastern Cape beach sands. The kimberlite ilmenites are chemically distinct and can be readily distinguished on the basis of their relatively high MgO, Fe₂0₃ and Cr₂O₃ contents. They can also be distinguished from ilmenites from other igneous rocks on the basis of unit cell dimensions, d-spacings, reflectivities and micro-indentation hardness. The ilmenites from a wide range of basic to granitic igneous rocks exhibit a limited compositional range in which the MnO content appears to increase with increasing Si0₂ content. Relatively insensitive indirectly determined parameters such as unit cell dimensions, reflectivities and micro-indentation hardnesses cannot be used to distinguish between the ilmenites from the different rock types in these classes. The titaniferous magnetites exhibit progressively decreasing Ti0₂ contents from a maximum in the basic igneous rocks to a minimum in the granitic types. The titaniferous magnetite typically exhibits varying degrees of deuteric alteration, while the microstructures developed can be interpreted 1n terms of the models presented in Part 1. Part 3 represents an extension of Part 2 and deals with a mineralogical investigation of the titaniferous iron ores in five South African basic intrusions. The Bushveld and Kaffirskraal ores consist of multi-phase titaniferous magnetite grains containing crystallographically oriented ilmenite, ulvospinel and pleonaste microintergrowths. Minor coarser-grained ilmenite is also present. The Usushwana ores are texturally similar but contain abundant lamellar ilmenite in place of the ulvospinel. The primary features are well preserved in the unmetamorphosed Bushveld and Kaffirskraal ores. The Usushwana ores have been slightly metamorphosed resulting in the extensive replacement of the titaniferous magnetites by sphene and chlorite aggregates. The ores from these three complexes cannot be beneficiated by conventional ore-dressing techniques and require direct metallurgical treatment for the recovery of Fe, Ti0₂ and V₂O₅. The metamorphosed Mambula and Rooiwater ores have been recrystallised to a varying degrees and consist of multi-phase titaniferous magnetite grains containing modified ilmenite and pleonaste microintergrowths. These modified microstructures differ from those encountered in titaniferous magnetites from unmetnmorphosed basic rocks and their degree of modification can be related to the degree of met amorphism. Variable amounts of coarse granular ilmenite are also present and their development is related to the metamorphic grade and degree of recrystallisation. These ores can be partially beneficiated to yield ilmenite- and lower-Ti0₂ magnetite concentrates in which V₂O₅ contents of the magnetic fractions are higher than those of the original ores. The Trompsburg ores differ from those of the other complexes in that they are Mg-rich and are characterised by the presence of abundant olivine. The titaniferous magnetites typically exhibit well-defined ulvospinel cloth textures and are often surrounded by small amounts of graphite. They show evidence of a variety of extensive late-stage alteration features. The ores from the five investigated complexes are compared with similar ores from the Bushveld Complex. The ores from each complex can be readily distinguished on the basis of their chemical compositions and textural relationships. These features can be related to their crystallisation his tories and, in some cases, to post-crystallisation processes. The microstructural evolution of the ores from each complex is interpreted in terms of the models developed in Part I.

- Description: Studies on delinquency fall into two groups, a statistical orientation and a qualitative approach. This study adopted the latter approach using Maslow's theory to investigate the relationship between unmet needs and stealing. It also attempted to explicate the function of stealing for each individual and focused upon interpersonal and intrapersonal aspects. The Rorschach, Thematic Apperception Test and the Draw a Person Test were administered to four white male adolescents who had stolen. Their ages ranged from 14 to 17 years. An analysis of each test was completed focusing upon the needs of the individual. In addition the case history and impressions gained during testing were included. It was found that unmet needs had resulted in stealing. Their personalities displayed common characteristics but differences were also evident. A summary was provided and the implications for therapy were then discussed.

- Description: The study of geodesics in space-time is essential to a comprehensive understanding of the physics of the field. Global properties, e.g. the singularity structure and completeness of space-time, can be related to the geodesic properties, thus it is through the solutions of the geodesic equation of motion that many of the global properties of space-time can be obtained in an easily interpretable form. However, it is usually very difficult to integrate the geodesic equations for the particle motion in the presence of a gravitational field (Introduction, p. 1)

- Description: The study of landforms has, to a large extent been neglected by exploration geologists. This is surprising because field geology is intimately related with landforms of one type or another. An understanding of the geomorphological history of a particular area will assist in the appreciation of the surficial environment, the processes of weathering, soil formation and duricrust (calcrete , ferricrete silcrete) formation. This has direct application in planning and interpreting geochemical sampling programmes. In order to understand the evolution of landforms it is necessary to study slope development in some detail. Agents of erosion and denudation constantly at work, remove detritus from hillcrests down to the drainage lines which form the local base level from whence material is transported down to the sea. The system is one of dynamic equilibrium, and the concept of grade is important in understanding hillslope evolution. Thus Section (1) of this discussion deals with past and present theories of hillslope evolution. Very little work has been done recently on the geomorphology of Southern Africa and the presently accepted classification of land surfaces is based on the work of Prof. L.C. King (numerous publications). However, through the more recent work of De Swardt and Bennet (1974) on the geomorphology of Natal, it is apparent that the present system of landform classification in Southern Africa requires widespread revision. The relationship of erosion cycles in Southern Africa to the late Jurassic-early Cretaceous break-up of Gondwanaland has received insufficient attention in the past. Erosion cycles bear an intimate relationship to offshore Cretaceous and Tertiary-Recent sedimentation. Valuable information on these sediments has only recently become available as a result of offshore exploration for oil. The findings of De Swardt and Bennet (1974) are summarized in Section (2) and the present land surface classification of Southern Africa is reviewed. Finally, some suggestions on a new interpretation of land surfaces in Southern Africa are given.

- Description: A description of the geochemistry of tungsten is given. The geochemical properties of tungsten have a strong influence on its mineralogy, distribution and abundance in crustal rocks and rock-forming minerals , and its migration/deposition within the ore-forming and supergene environments. The behaviour of tungsten during migration, from source to site of deposition, within the crust is discussed in some detail and environments considered favourable to the concentration of tungsten ore minerals are suggested. All major types of tungsten ore deposit are described with emphasis placed on those of greater economic importance. Characteristic features of each type of deposit are particularly emphasized in order to provide clear guidelines to exploration. Hydrothermal, pyrometasomatic and stratabound tungsten deposits present themselves, economically, as the most important exploration targets. The recently developed concept of syngenetic stratabound tungsten mineralisation is outlined. Exploration for deposits of this type should be aimed predominantly, but not exclusively, at volcano-sedimentary sequences of Lower Palaeozoic age, particularly within regions known to contain occurrences of Sb and Hg. Tungsten deposits commonly contain concentrations of one or more of the following metals: Sn, Sb, Bi, Mo, Au and Ag. The presence and possible extractive value of these metals, together with commonly associated metal impurities such as As, must always be taken into account in a feasibility study , Adobe Acrobat 9.53 Paper Capture Plug-in
