- Description: Globally, countries, institutions, and organizations are investing time, resources, and human capital on finding best solutions to address poverty, inequality and unemployment; and importantly on achieving sustainable development. This study sought to investigate how social enterprises in Buffalo City Metropolitan Municipality (BCMM) contribute to sustainable social development within the municipality and the country at large. The study endeavoured to answer the following research questions: what is the knowledge level among the selected stakeholders on social enterprise in BCMM? What is the scope, application, and sustainability of selected social enterprises in BCMM? What is the contribution of selected social enterprises in social development in BCMM? What are the bottlenecks associated with the application of social entrepreneurship in BCMM? These questions were answered through mixed methods approaches and techniques, where both qualitative and quantitative data was collected and analysed. The data was collected through in-depth interviews (key informant technique) and a min-survey which was administered to users of the social enterprises. Qualitative data was analysed thematically, while quantitative data was statistically analysed with help of SPSS software. The interpretation of the findings was premised on pragmatic and transformative paradigms. The study further used theoretical lenses such as empowerment theory, capability approach and positive theory of social enterprise to support and explain the findings. The main findings showed that: the selected stakeholders conceptualized social enterprises through the African lens of communal living; the social enterprises widely provided their services across a range of sectors and geographical locations; the social enterprises had direct and indirect contribution to socio-economic development in BCMM. This was specifically through provision of employment, training and skill development among others; the future of social enterprises in the country is bright as many sectors presented opportunities for social investment; and social enterprises face financial constraints, lack of skills in the sector, and competition from the mainstream market. The recommendations from this study address government entities, social services providers and practitioners, social enterprises, and researchers on pertinent endeavours to improve the growth and development of social enterprises. The study concludes that social enterprises are: vital vehicles of socio-economic development, more especially for the marginalized segment of the populations; tools for reducing inequality; platforms for innovations, community participation and conduits of empowerment interventions. Thus, social enterprises play dynamic role and presents potential for capable sustainable social development in the local communities and the South African community at large.

- Description: This thesis focuses on mineral governance and how it can contribute to ameliorating human development challenges in Ghana. The study adopted the human centered mineral resource governance approach to assess the mineral governance structure in Ghana and identified that, the current system is a colonial legacy and does not promote human development in Ghana. The study, whilst recognizing the legacies of colonialism, argues that in order for mineral resources to be managed responsibly to promote human development, there should be a paradigm shift to focus on how mineral resources are governed. As a result, the study, relying on the human centered development approach investigates how mineral resources can be governed to promote development in Ghana, with specific focus on the mineral wealth Western Region of the country. Due to the finite nature of mineral resources, the human centered development approach argues that revenues from mineral resources should be invested in human capacity building and medical care delivery. Further, the mining sector should be integrated with other non-mining sectors of the economy to create jobs and provide alternative livelihoods which will go a long way to assist in the general expansion and growth of the country‟s economy. Although this thesis is a case study of mineral governance in Ghana, it can serve as a springboard to appreciate the role mineral governance can play in promoting people centered development in other sub – Saharan mineral wealth countries.

- Description: Local government processes require meaningful and effective participation from both citizens and their governments in order to remain truly democratic. This project investigates the use of mobile phones as a tool for supporting this participation. MobiSAM, a system which aims to enhance the Social Accountability Monitoring (SAM) methodology at local government level, has been designed and implemented. The research presented in this thesis examines tools and techniques for the development of cross-platform client applications, allowing access to the MobiSAM service, across heterogeneous mobile platforms, handsets and interaction styles. Particular attention is paid to providing an easily navigated user interface (UI), as well as offering clear and concise visualisation capabilities. Depending on the host device, interactivity is also included within these visualisations, potentially helping provide further insight into the visualised data. Guided by the results obtained from a comprehensive baseline study of the Grahamstown area, steps are taken in an attempt to lower the barrier of entry to using the MobiSAM service, potentially maximising its market reach. These include extending client application support to all identified mobile platforms (including feature phones); providing multi-language UIs (in English, isiXhosa and Afrikaans); as well as ensuring client application data usage is kept to a minimum. The particular strengths of a given device are also leveraged, such as its camera capabilities and built-in Global Positioning System (GPS) module, potentially allowing for more effective engagement with local municipalities. Additionally, a Short Message Service (SMS) gateway is developed, allowing all Global System for Mobile Communications (GSM) compatible handsets access to the MobiSAM service via traditional SMS. Following an iterative, user-centred design process, a thorough evaluation of the client application is also performed, in an attempt to gather feedback relating to the navigation and visualisation capabilities. The results of which are used to further refine its design. A comparative usability evaluation using two different versions of the cross-platform client application is also undertaken, highlighting the perceived memorability, learnabilitv and satisfaction of each. Results from the evaluation reveals which version of the client application is to be deployed during future pilot studies.

- Description: Much prior research has shown that if students have a poor command of the language in which they are taught and assessed, they experience a complex and deep learning disadvantage (Barton & Neville-Barton, 2003). Abedi (2006) mentions, in particular, that unnecessary linguistic complexity can threaten the validity of examination items and thus compromises the fairness of the assessment for English language learners. In Clarkson’s (1991, p. 31) research it was found that for the English language learners in the study “comprehension errors [made] up a high proportion of the errors made when…students attempt[ed] to solve mathematical word problems”. In an attempt to explore whether this was the case for a group of National Certificate (Vocational) [NC(V)] students at an FET college, the research conducted in this study focused on describing the cognitive and linguistic complexity of Level 4 Mathematical Literacy examination items as well as the types of responses from a sample of students. A mixed-methods case study design was selected. Student errors were classified as either due to mathematical literacy-related sources, or language-related sources and the question was asked as to how the cognitive and linguistic complexity of items might be related to the types of errors made. Statistically significant correlations were found between the linguistic complexity of items and language-related errors, and between the cognitive complexity of items and all types of errors. It was also possible to identify which language features, in particular, were statistically significantly correlated with linguistic complexity, namely: prepositional phrases; words of 7 letters or more and complex/compound sentences. As was expected, the majority of errors were categorised as mathematical literacy-related. However, as many as 19.22% of all errors made were identified as language-related. While the scope of the study prevents any generalisations from being made, the results indicate a need for a larger-scale study of this nature to determine if the complex and deep learning disadvantage mentioned by Barton and Neville-Barton (2003) does exist with regard to the assessment of Mathematical Literacy for NC(V) students who are English language learners (Barton & Neville-Barton, 2003).

- Description: Despite South Africa’s constitutional commitment to multilingualism, literacy in English is important in education and the economy. English is widely perceived as the language of opportunity, and many South African primary schools have chosen English as their language of learning and teaching (LoLT). In terms of South Africa’s 1997 Language in Education Policy, this choice means that such a school has to comply with English Home Language curriculum requirements. In situations where few learners (or teachers) have English as a home language, the choice of English as LoLT poses particular challenges, perhaps most crucially in the early years of literacy development. This investigation explores the work of an intermediate phase teacher working in the Eastern Cape province at a “no-fee” school where English is the chosen LoLT, but where the majority of learners have isiXhosa as their home language. A qualitative interpretive approach was used to focus on the teacher’s strategies for developing her Grade 5 learners’ reading literacy in English. Data were derived via lesson observation and in-depth interviewing. Fourteen of the teacher’s English lessons were observed and she was interviewed twice. Analysis of the data shows that few learners meet the reading literacy levels outlined in National Curriculum Statement guidelines. The teacher, working as she is in what are essentially subtractive bilingualism circumstances, is poorly equipped to cope with the task of developing her learners’ reading literacy. I argue that educational policy, contributing as it does to the ongoing displacement, by English, of many South African children’s home languages, not only undermines the post-apartheid Government’s attempts at linguistic equity, but also contributes significantly to unequal reading literacy achievement across South Africa’s different socio-economic sectors. Department of Basic Education officials, academics and others involved in decision-making around teacher education and development need to work together to interrogate policy and put in place more effective support structures to help teachers better cope with the exigencies outlined above.

- Description: The medicinal chemistry of selected marine algae indigenous to South Africa was investigated. Following the isolation and characterisation of a number of new and known compounds, the associated in vitro cytotoxic profiles of these new compounds was investigated. Plocamium maxillosum yielded two new cyclic polyhalogenated monoterpenes which were characterised as 2E-chloromethine-4E-chlorovinyl-4-methyl-5-cyclohexen-1-one (2.1) and 2Z-chloromethine-4E-chlorovinyl-4-methyl-5-cyclohexen-1-one (2.2) on the basis of one and two dimensional NMR spectroscopic data and MS analysis. These compounds were also found to have good cytotoxic activity against breast cancer cell lines. Although these compounds are based on a regular monoterpene skeleton, they represent an uncommon feature not often seen in cyclic halogenated monoterpenes from marine algae. Plocamium robertiae yielded one new cyclic polyhalogenated monoterpene identified as 4,5- dibromo-5-chloromethyl-1-chlorovinyl-2-chloro-methylcyclohexane (2.6) and one known compound called 2,4-dichloro-1-chlorovinyl-1-methylcyclohexane-5-ene or Plocamene D (2.9). Portieria hornemannii was collected from Port Edward in Natal and yielded three new compounds, namely; 3Z-1,6-dibromo-3-(bromomethylidene)-2,7-dichloro-7-methyloctane (3.1), 1E,3Z-1,6-dibromo-3-(bromomethylidene)-7-chloro-7-methyloct-1-ene (3.2), 1Z,3Z- 1,6-dibromo-3-(bromomethylidene)-7-chloro-7-methyloct-1-ene (3.3), and one known compound, namely; 3S,6R-6-bromo-3-(bromomethyl)-3,7-dichloro-7-methyloct-1-ene (3.4). Compounds 3.1 and 3.2 showed no cytotoxic activity against breast cancer cells. Another Portieria hornemannii sample was collected from Noordhoek in the Eastern Cape, it yielded one known compound referred to as 3Z-6-bromo-3-(bromomethylidene)-2,7- dichloro-7-methyloct-1-ene (3.5), as well as one new compound called portieric acid A (3.6) or 5-bromo-2-(bromomethylidene)-6-chloro-6-methylheptanoic acid. Portieric acid A showed slight cytotoxic activity and also represents a new class of compound within the genus Portieria. The isolation of secondary metabolites from the South African red alga, Laurencia glomerata, yielded two known compounds; 7-hydroxylaurene (4.9) and cis-neolaurencenyne (4.12), as well as one chamigrane related compound (4.11). Laurencia flexuosa yielded one known compound called 3Z-bromofucin (4.13). Using 1H NMR, GC and molecular systematics, a novel method for identifying different species of Laurencia was also investigated.

- Description: Part One of the research seeks to establish a context wherein certain assumptions pertaining to the interpretative dimensions of understanding the image in art therapy can be considered and reviewed. Notions about the image, meaning and reality are discussed both in terms of how they relate to current art therapy practice, and how they may be alternatively thought about, both from the perspective of ancient Hellenic Greek thought, and more contemporary thought, particularly that of phenomenological and philosophical-hermeneutics. Part Two of the research investigates the phenomenon of understanding the image in an art therapy situation, with a view to reconsidering certain of the assumptions raised in the first part of the thesis (phrased in the form of research questions). It did this utilizing a qualitative method, by exposing four respondents (patients), and two therapists to an art therapy situation in which images were created out of clay. The respondents (patients) and therapists articulated their understanding of the image production procedure, and the meaning of the images created. The way understanding occurred in the empirical part of the research was explained and illustrated by means of the hermeneutic circle, which was operational on a number of different levels. The results of the research suggest that the meaning of the image in art therapy is a creative synthesis, which emerges from within a dialectics of exchange. This exchange involves a number of meaning-generating contexts, of which the patient’s experience, and the therapist’s knowledge, form only a part. The outcome of this exchange is the derived meaning of the image, which represents a ‘fictional’ world that gives the patient and therapist a way of understanding the patient’s situation. The process of the research, which investigates the way understanding of the image in art therapy occurs, is at the same time, an application of the principles of understanding

The outcome of this exchange is the derived meaning of the image, which represents a ‘fictional’ world that gives the patient and therapist a way of understanding the patient’s situation. The process of the research, which investigates the way understanding of the image in art therapy occurs, is at the same time, an application of the principles of understanding

- Description: Various chelating ligands have been designed and synthesised; these include amino-amide ligands, tetraacetic acid systems and sulfur-containing amide ligands. Difficulties in the synthesis and purification of the amino-amide ligands were largely overcome, permitting the mono acylation of ethylenediamine and the synthesis of bis(2-aminoethyl)-2-benzylpropanediamide. Novel tetraacetic acid ligands, based on the propanediamide backbone and targeted as EDTA analogues, were obtained from their methyl and benzyl esters; but the instability of the tetraacids prevented their full characterisation. Bidentate, tridentate and tetradentate sulfur-containing monoamide ligands, based on the ortho-thio acetanilide moiety, were designed to specifically chelate platinum and palladium in the presence of base metals. In their synthesis, thiocyanation was used to introduce the orth-thio group on para-substituted anilines, and further functionalisation was achieved via appropriate protection of nucleophilic sulfur moieties. A range of tetradentate, sulfur-containing diamide ligands was also synthesised by reacting substituted 2-mercaptoacetanilides with 1,2- dibromoethane. Novel ligands were characterised by spectroscopic (¹H and ¹³C NMR; IR and M S) techniques and elemental (combustion and high resolution MS) analysis. Computer modelling and ¹H NMR chemical shift data have been used to explore the conformational preferences of the sulfur-containing acetanilide ligands. The macrocyclic ligands and systems with ortho-methylthio substituents appear to exhibit the greatest degree of coplanarity of the aromatic and amide functions. Solvent extraction studies revealed that the sulfur-containing amide ligands selectively extracted palladium(II) from platinum(II), copper(II}, nickel(II} and cobalt(II}. Even though the palladium(II} was extracted from an acidic medium, certain monoamide ligands were able to complex palladium(II) through their sulfur and deprotonated amide nitrogen donors, a trithia monoamide ligand being observed to displace all the chloride ligands on palladium to form a monomeric tetracoordinate complex. The diamide ligands, however, appeared to favour extraction of palladium(II) by coordination through their sulfur donors, forming 5-membered sulfur-sulfur chelates. In basic media (pH 8-9), selected sulfur-containing monoamide and diamide ligands have been shown to complex platinum(II) and palladium(II) through their sulfur and deprotonated amide nitrogen donors. At neutral pH, a dimercapto monoamide ligand has been shown to complex platinum from cisplatin with partial expulsion of the ammine ligands, while a macrocyclic trithia monoamide ligand has been observed to complex platinum from tetrachloroplatinate with concomitant deprotonation of the amide nitrogen. Where possible, the complexes were characterised by infrared and ¹H NMR spectroscopy and have also been studied using the computer modelling soft-ware programmes, Momec® and Hyperchem®.

Modelling parallel and distributed virtual reality systems for performance analysis and comparison

- Description: Most Virtual Reality systems employ some form of parallel processing, making use of multiple processors which are often distributed over large areas geographically, and which communicate via various forms of message passing. The approaches to parallel decomposition differ for each system, as do the performance implications of each approach. Previous comparisons have only identified and categorized the different approaches. None have examined the performance issues involved in the different parallel decompositions. Performance measurement for a Virtual Reality system differs from that of other parallel systems in that some measure of the delays involved with the interaction of the separate components is required, in addition to the measure of the throughput of the system. Existing performance analysis approaches are typically not well suited to providing both these measures. This thesis describes the development of a performance analysis technique that is able to provide measures of both interaction latency and cycle time for a model of a Virtual Reality system. This technique allows performance measures to be generated as symbolic expressions describing the relationships between the delays in the model. It automatically generates constraint regions, specifying the values of the system parameters for which performance characteristics change. The performance analysis technique shows strong agreement with values measured from implementation of three common decomposition strategies on two message passing architectures. The technique is successfully applied to a range of parallel decomposition strategies found in Parallel and Distributed Virtual Reality systems. For each system, the primary decomposition techniques are isolated and analysed to determine their performance characteristics. This analysis allows a comparison of the various decomposition techniques, and in many cases reveals trends in their behaviour that would have gone unnoticed with alternative analysis techniques. The work described in this thesis supports the Performance Analysis and Comparison of Parallel and Distributed Virtual Reality systems. In addition it acts as a reference, describing the performance characteristics of decomposition strategies used in Virtual Reality systems.

- Description: The interpretations of the war of 1835 and the identity of the Fingo that were presented by the English settlers, have remained the mainstays of all subsequent histories. They asserted that the war of 1835 was the fault purely of 'Kaffir' aggression, that it was controlled by Hintza, the paramount chief, and that the ensuing hostilities were justifiable colonial defence and punishment of the Africans. The arrival of the Fingo in the Colony, it was claimed, was unconnected with the war. It was alleged that the seventeen thousand Fingo brought into the Colony in May 1835 were all Natal refugees who had fled south from the devastations of Shaka and the 'mfecane', and who had then become oppressed by their Gca1eka hosts. Both of these 'histories' need to be inverted. The 'irruption' of December 1834 was not unprovoked Rharhabe aggression, but the final response to years of the advance of the Cape Colony. Large areas of Rharhabe land had been expropriated, and their cattle regularly raided. Their women and children had been seized and taken into the Colony as labourers. The attacks were carried out by only a section of the Rharhabe on specific areas in Albany. The damage caused, and stock taken, was vastly exaggerated by the colonists. The Cape Governor, D'Urban, and British troop reinforcements arrived in Albany in January, and the Rharhabe were invaded two months later. D'Urban later invaded the innocent Gcaleka, took cattle, wreaked havoc and killed Hintza after he refused to ally with the Colony. The Fingo made their appearance at this moment. They were not a homogenous group. There were four categories within the term: mission and refugee collaborators (who were given land at Peddie and had chiefs appointed), military auxiliaries, labourers, and later, destitute Rharhabe seeking employment in the Colony. Only a small minority of the total Fingo were from Natal. The majority of the Fingo appear to have been Rharhabe and Gcaleka women and children, captured by the troops during the war and distributed on farms in the eastern districts to ameliorate the chronic labour shortage. Thus, instead of the year 1835 being one of great loss for the eastern Cape, as claimed by the settler apologists, it was a catalyst to the economic development of the area. All Rharhabe land was seized, to be granted as settler farms. Well over sixty thousand Rharhabe and Gcaleka cattle were captured and distributed amongst the colonists. The security threat of the adjacent Rharhabe and the independent Gcaleka was removed. And a large colonial labour supply was ensured.

The applicability of two simple single event rainfall-runoff models to catchments with different climate and physiography

- Description: The study presents the results of applying two isolated event, constant runoff proportion, conceptual models to a range of catchments drawn from various climatic and physiographic regions of South Africa and the USA. The models can be operated in either lumped or semi-distributed modes. The research progressed through the following stages. The initial stage involved the calibration of both models on two sets of catchments so that an initial evaluation of the performance of the models could be carried out and any deficiencies in the model structure identified, and where practical, corrected. The models were then calibrated on a further 8 catchments. An important result of the calibration is that for both models to produce reasonably acceptable simulations, at least one parameter has to vary between storms on the same catchment to account for variations in storm or antecedent moisture characteristics. The next stage consisted of compiling quantitative descriptions of the physical characteristics of the catchments and rainfall events and an attempt to relate the calibrated parameter values to relevant physical characteristics for the purpose of estimating parameter values when calibration is not possible. Despite the difficulties encountered in quantifying some of the hydrological characteristics the general trends exhibited by many of the relationships are encouraging and the format of the combinations of physical variables used, do make sense with respect to the original parameter conceptualisations. The relationships between storm characteristics and parameters of both models are less satisfactory. There is a high degree of scatter and the between-catchment variation in the form of the relationships, indicates that the derived relationships are likely to be of little use for parameter estimation purposes. The final stage involved a validation exercise in which new parameters were estimated from the physical variable-parameter relationships for all the catchments previously used, as well as a further four. The new parameters were used to re-simulate all the storms and comparison of these results were made with the original calibration results. Both models produced poor results and are unlikely to give reliable results where calibration is not possible. The parameter relationships for the parameters related to storm characteristics are so catchment specific that transfer to other areas will produce unpredictable results.

- Description: Lovedale was founded by the Glasgow Missionary Society as an eduational centre for Africans. Education was to be adapted to the lives of the Africans which would be a departure from the English classical tradition. This meant that emphasis was placed on vocational training and that academic education focussed on the study of English rather than the Classics. But the importance of mother-tongue education was also stressed. The missionaries placed emphasis on village education, whereby the African would be taught skills and crafts that would be useful to him in life. Education, they argued, should also aim at character-training and at spreading the Christian message. They also wanted to see co-operation between the Church and the State in the education of the African. Vocational education was designed to create African artisans who would be able to compete with Whites; but it also aimed at emphasizing the importance of industry in building up character. The Lovedale Press illustrates vocational training in progress, dealing with the difficulties that arose when African printers came into competition with Whites. But the missionaries also used the Press to propagate the Christian message and to promote African literature. An ideological rift began to open up between the missions and the new Black political beliefs of the Second World War. This led to the Lovedale Riot which is considered in the broader framework of sociopolitical unrest within the country. After the 1948 Election an ideological rift also developed between the missions and the State. This study concludes by examining the introduction of the Bantu Education Act and the Lovedale response to this. It was felt that although Bantu Education threatened to undermine their educational endeavour, they should nevertheless cooperate with the system in order to save what they had built up.

It is held that the social work view of man, and the profession's declared objectives, determine a structure and function for the client.which cause the social worker to resort to psychological and sociological perspectives in his intervention programme. However, the two disciplines concerned formulate their respective perspectives without regard to each other. The disparity between these perspectives present problems when they are incorporated into social work knowledge. The latter, as it is, is characterized by an unco-ordinated body of suppositions, facts, thoughts and theories. The social work literature on the use of the systems approach displays a lack of detailed description of general systems theory and the open living system. Because of this shortcoming it was decided to pay particular attention to general systems theory and the concept of the open living system. Since a system's view of man forms a firm basis for the appreciation of systems theory in psychology and sociology it was decided to include such a consideration. Following on this is an analysis of two perspectives held to be particularly relevant to social work, viz. the personality system and the social system. This leads finally to a description of the social work client as a system, as a sub-system and as a supra-system. Provision is made for the incorporation of psychological and sociological perspectives in social work intervention. It is subsequently concluded that the application of general systems theory has advantages for social work. It facilitates the incorporation of perspectives for psychology and sociology without distortion, promotes the integration and consolidation of social work knowledge, and brings the discipline into relation with the disciplines of psychology and sociology

This survey was to form the basis for development planning in view of the expected benefit to the region of the Orange River Project. Similar requests were also received from the Midlands Planning Association and the South Eastern Areas Development Association. When Rhodes University consulted the Department of Planning, which strongly supported the principle of a regional survey, it was decided that, although Port Elizabeth and its hinterland comprised a logical economic unit, the area should be sub-divided. The University of Port Elizabeth was entrusted with the responsibility for an analysis of the metropolitan area, while the Institute of Social and Economic Research of Rhodes University was commissioned to undertake a socio-economic survey of the inland areas. This thesis on the transport infrastructure of the Cape Midlands and Karroo Regions represents one aspect of the survey.

- Description: This work encompasses an inquiry into the role of the entrepreneur in economic development, and a report of interviews with eighty African businessmen in the Transkei, Ciskei and some urban locations. South Africa provides a particularly interesting field for the study of African enterprise insofar as it is possible to examine the evolution of entrepreneurship in two fundamentally different environments - namely rural reserves and large urban areas. Furthermore, there has been a substantial increase in the number of African entrepreneurs during this century. The study achieves added significance in view of the wide racial income differentials which are an endemic feature of South African socio-economic existence; moreover, there is a great deal of evidence to suggest that, despite the high real growth rates during recent years, the racial income gap is widening. A corollary to this is the worsening of the relative - though not necessarily the absolute - economic position of the Black population. Hence : "the fundamental question for South Africa's economic future revolves around the income relationship between the Whites and the African segment of the non- White group." At present a great deal of pressure is being exerted on White employers to adopt more racially equitable systems of remuneration, and on the Government to relax the industrial colour bar. Although such measures would probably have a positive influence in preventing the gap from widening still further, there is reason to believe that their effectiveness would be limited. The justifications for this assertion are twofold: a) As Allister Sparks has pointed out, "as long as (Blacks) are limited to being hirelings of (Whites), their progress will necessarily remain stunted. Because of race prejudice they will not be promoted as readily as Whites of equal ability. There will not be Black managers and company directors. They will be held down by a vicious circle of disadvantages: prejudice will deprive them of promotion, which will deprive them of experience, which will provide the pretext for not promoting them. b) There is much convincing evidence to show that property ownership rather than wages is the basic factor determining income distribution. Information indicative of the extreme racial inequality of property ownership in South Africa is given by Spandau, who has shown that in 1960 'other income' (i. e. rent, interest and profits) formed 119% of work income of Whites, and only 19% of the work income of Africans. 2 In the absence of cataclysmic social change, the development of African entrepreneurial talent emerges as a possible means of escaping from this apparent impasse. This does not of course imply that even a fairly large increase in the number of African entrepreneurs would automatically result in raising the living standards of a substantial portion of the Black population. Nevertheless, it would represent a positive move towards redressing the inequalities in property ownership and facilitate the acquisition of organizational skills, which in turn implies a better utilization of human resources than exists at present.

Some aspects of the Franco-German economic relations between the two world wars

- Description: From Preface: In this thesis I have aimed at covering a field in Economic History where not many suitable publications are available in English. During the interwar period, the maintenance of peace and harmonious international relations was directly dependent on a reconciliation of the conflicting interests between France and Germany. In studying the economic implications of the Franco-German antagonism, I have tried to throw light upon the crucial role which this relationship played. The Appendix offers a quantitative survey of economic conditions in the two countries and of the relevant production and exchange problems. To assist the reader who is not completely familiar with this period, a brief summary of the relevant conferences, agreements and treaties is also offered in the Appendix, as well as some short biographical notes. I would like to make it clear, however, that this thesis is neither supposed to be a paraphrase of the Appendix, nor a mere treatise on the commercial relations between the two countries concerned. I aimed rather at revealing the forces behind the events and at illustrating how economic problems became quite often subject to political and military considerations. When trying to attain some understanding of Franco-German relations, it seems advisable to look not only at the interbellum period, but in the first instance to become aware of the currents of history which finally led to the two disastrous World Wars.
