  • Description: The African continent is endowed with vast natural resources of minerals, such as cobalt, diamonds, gold, bauxite, iron, platinum, silver, uranium and mineral oil. Oil is unequally distributed in the continent, with some countries, such as Cameroon, Chad, Congo Brazzaville, Equatorial Guinea, Gabon and South Africa, being particularly well endowed. These natural resources can help accelerate development on the continent, especially in Gabon and South Africa if used strategically. This dissertation gives an overview of the international instruments, which play a key role in petroleum legislation and development. At the global level, the international legal instruments related to the permanent sovereignty over natural resources (PSNR), such as the 1962 Resolution 1803 (XVII) on Permanent Sovereignty over Natural Resources indicates that States have the rights to exploit freely national resources and wealth, use and dispose their natural resources for the realisation of their economic development in accordance with their national interest. The PSNR must be exercised in line with indigenous peoples’ rights and the respect of rules concerning the expropriation. At the African level, with regard to the right to the State to exploit freely natural resources, the African (Banjul) Charter on Human and Peoples’ Rights of 1981 has similar provisions as the Resolution 1803. The African (Banjul) Charter specifies that no peoples can be deprived of the right to dispose their natural resources. The African Commission on Human and Peoples’ Rights is tasked to interpret the African (Banjul) Charter. The Resolution on Human Rights-Based Approach to Natural Resources and Governance has also indicated principles in relation to the governance of natural resources. At the regional level, the Constitutive Treaty of the Central African Economic and Monetary Community (CAEMC) of 1994 and the Southern African Development Community (SADC) Treaty of 1992 do not provide explicit provisions relative to the PSNR and the management of natural resources. Therefore, it is important to examine if at the national level, the domestic instruments of both States deal with the PSNR.

  • Description: Business sustainability is a fundamental concern amongst business leaders and it is imperative that business defines an environmentally and socially sustainable path to financial prosperity. This focus on sustainable business practices has been caused by the perceived contribution of businesses to undesirable conditions such as environmental and social degradation including global warming and the global financial crises. This study suggests that a leadership style that differs from leadership that is currently causing business unsustainability is needed in order to achieve the goal of sustainable business practices. This study therefore proposes a new kind of leadership, called conscious leadership. The main contribution of the study is to increase the achievement of sustainable business practices by investigating the importance of conscious leadership in achieving this objective. Convenience sampling was used to select senior managers and directors from mainly JSE listed companies. This resulted in a total of 371 usable questionnaires (317 from listed companies and 54 from unlisted companies) being received. A quantitative approach was adopted to investigate whether conscious leadership would be related to increased sustainability competencies and more effective sustainability-related corporate governance and whether these in turn would increase sustainability behaviours which would generate sustainable business practices as measured by financial, social and environmental performance. Regression analyses were conducted to investigate the hypothesised relationships among these variables. Pearson correlations and descriptive statistics were also calculated. The empirical results showed that respondents in this study regarded conscious leadership, not as a separate construct, but as a way they governed their businesses. The empirical results showed that corporate governance and systems thinking competency had a strong interactive relationship and should therefore be cultivated within business firms. Corporate governance (including conscious leadership) and systems-thinking competency were positive influencers of employee relations, equal opportunities and workforce diversity. The empirical results however showed that corporate governance (including conscious leadership) had a negative influence on profitability. The present study cannot argue for the discouragement of corporate governance (including conscious leadership), as measured in this study, because reduced corporate governance would decrease healthy employee relations and the latter would decrease the achievement of equal opportunities and workforce diversity in these firms. A decrease in healthy employee relations would decrease profitability. The most important finding of this study is that senior managers and directors of big business firms, mostly JSE-listed companies, regarded conscious leadership as an important part of corporate governance. Corporate governance that includes conscious leadership must be developed to higher levels in business firms, so that the negative and not-significant relationships to profitability as viewed by lower and high conscious leaders respectively can be changed to positive relationships.

  • Description: The role of natural resources in African conflicts has been subject to extensive scholarly analysis. However, much of this analysis has taken a narrow economic reductionist bias. As such, it is imperative that the dominant assumptions and accepted concepts and theories about the role of natural resources in African conflicts be re-examined. The aim of this thesis is to offer a revaluation of the role of coltan during the Democratic Republic of Congo’s (DRC) Second War (1998-2003) through a critical engagement with the resource wars literature. The purpose is to offer a re-reading of the role of coltan in the DRC Second War and the broader regional and global economic context in which this conflict took place. It rejects the commonly cited assumption that the presence of coltan in the DRC means it is an initiator of conflict. Rather, this thesis argues that the central role of coltan in the DRC Second War was as an aggravator of conflict in that its exploitation was used by different parties to fund their military and political ambitions. This thesis also argues that the DRC’s weak state structures and pivotal role within the Great Lakes region, as well as the international trade of coltan and the nature of the DRC coltan mining industry are all key factors in understanding coltan exploitation in the country’s Eastern Region during the Second War.

  • Description: The complexity of the South African society due to past systematic exclusion of some communities from economic activities resulted in the triple challenge of poverty, inequality and unemployment. Although various economic policies had been developed since the advent of the democratic dispensation in 1994, these policies focused on levelling the economic environment, poverty alleviation and massive social security system. However, despite all the interventions, South Africa remains one of the most unequal societies in the world. This is profiled by the mushrooming of informal settlements around cities with job seekers and frequent protests by people who are impatient to experience improvement in their quality of life and who feel cheated out of their social contract. Advocacy from the governing party’s tripartite alliance towards a developmental state had placed more obligations on the government. This requires deliberate interventions through policies implementation to improve or at best alleviate the well-being of the citizenry. A survey conducted in the township of Khayelitsha to assess the impact of such economic policies on the development of entrepreneurship. Khayelitsha is one of South Africa’s largest townships, an informal settlement profiled by unemployment, poor infrastructure and unavailability of basic services. The study explored the entrepreneurial perception, start-up barriers, entrepreneurship climate, and general cultural factors relating to the environment of entrepreneurship development. The results reveal that despite the various economic policies, high level of unwillingness of citizens towards entrepreneurial activity and business venture is rife notwithstanding the high level of unemployment and poverty. The antidote to these challenges would be a rapid entrepreneurship drive among people most affected that would cause them to mind their own business” and become “masters of their own destinies. Given the complexity and massiveness of the challenges, the conclusion shows that a pragmatic solution is required. Therefore, the emancipation of entrepreneurship development in South Africa townships needs attention. The recommended solution is a pragmatic and innovative strategy based on the acronyms NEEDS HELP which stand for Neighbourhood Enhancement and Environmental Development Strategy and Holistic Entrepreneurial Lifestyle Programme. , Thesis (PhD) -- Faculty of Management and Commerce, 2015

  • Description: The research problem was based on the private sector implementation of Responsible Tourism, since 1996, perceived to be slow and challenging (Frey & George, 2010: 107). The South Africa Government proposed Responsible Tourism as the guiding principle for sustainable tourism development (Goodwin, 2011: 138). The problem is compounded by shortcomings identified in the nature of the research conducted about tourism and communities and the methodologies used. Tourism-Community relationships Theory was applied as the conceptual framework of the study. This theory advocates a holistic approach when conducting research about the impacts of tourism, encompassing community perspectives, attitudes, reactions and considerations for the future development and control of tourism (Pearce, Moscardo & Ross, 1996: 2). The insights gained contributed an emic understanding of the keyinformants’ perspectives imparted in their own language. This study is located in the Interpretevist paradigm, underpinned by Constructivist philosophy. Meaning is created through the reality of key-informants, their perspectives and the interaction of individuals in a community (Cresswell, 2014: 8). The Instrumental Case Study Approach (Stake, 1995) contributed an etic perspective in terms of the researcher’s interpretations. The single, qualitative case was applied to gain deeper insights about the phenomenon of Responsible tourism. The case investigated was Stormsriver Adventures (SRA), an eco-adventure tourism business in the Tsitsikamma tourism destination in the Eastern Cape region of South Africa. SRA is reputed to be business best practice in its implementation of Responsible Tourism. Data triangulation was established through multiple methods of data collection, namely in-depth interviews with key-informants, documentation sourced from them and researcher observation. Data analysis methods, namely direct interpretation, categorical aggregation, pattern seeking and naturalistic generalisations (Stake, 1995), were used. The member checking process assisted with establishing data triangulation as keyinformants corroborated or dispelled the researcher’s interpretation of data. Findings were structured according to within-case themes, namely SRA’s perspective of its Responsible Tourism practices, the community’s perspective of SRA’s Responsible Tourism practices and perspectives about the future development and control of tourism. The study contributes new theoretical insights through applying the inductive approach to selected findings. Findings indicate that the perspectives of the community are divided. SRA keyinformants conveyed positive economic, social and environmental impacts of SRA’s Responsible Tourism practices. Key-informants not directly linked to SRA raised negative economic impacts and questioned the accuracy of SRA’s marketing messages. Within-case conclusions are that it is not the responsibility of one tourism business that practices Responsible Tourism to achieve sustainability within the tourism destination. To this end it is recommended that SRA and the community find common ground and that the misunderstandings that exist, be addressed. The study concludes that in order to achieve successful Responsible Tourism- Community Relationships, a holistically and integrated approach is required. To this end the recommendations made provide an implementation framework within the context of a tourism destination. The study adds value to the field knowledge about the implementation of Responsible Tourism by the private sector in South Africa and also contributes new knowledge to the field of tourism in terms of the particular methodology used.

  • Description: South African history is rooted in racial identities, inequalities and injustices, which the post-apartheid government has sought to address for twenty years since 1994. The transition to a post-apartheid society though has been a difficult one with the social structure and everyday life still marked by the racial past. Though racial classifications on an official basis no longer exist, racial identities continue to pervade the country. Of particular significance to this thesis are black identities including the possibility of black inferiority, which I examine in relation to black post-graduate university students in contemporary South Africa, specifically at Rhodes University. In examining this topic, I draw extensively on the work of Frantz Fanon, who wrote about both colonial society and the emerging post-colonial experience. Fanon was a young black intellectual whose work was in part based on his own experiences of being a once-colonised black person in a world which he perceived as being dominated by whiteness. In his work he expresses his own perceptions of whiteness and how the black identity has come to be shaped by and around this dominant white foundation. Fanon extensively discussed the lives of black intellectuals and elites, and demonstrated how the black identity becomes shaped by and around the world of whiteness. In doing so, he raised a range of themes, such as black inferiority, mimicry and double consciousness. I draw upon the work of Fanon in a critically sympathetic manner to delve into the experiences of black postgraduate students as they negotiate their way through a university setting dominated by a white institutional culture. I bring to the fore the argument that the racial identities of these students is not fixed and sutured but, rather, is marked by considerable fluidity and ambiguity such that black identity must be understood not just as a state of being but also as a process of becoming.

  • Description: A description of gametogenesis in the panga Pferogymnus laniarius, a common endemic seabream species inhabiting the Agulhas Bank, South Africa, is presented. After sexual maturity, oogenesis and spermatogenesis continued throughout the year and were found to be similar to these processes in other seabream species and teleosts in general. Analysis of maturity data over the past two decades revealed a significant change in both age and size-at-maturity, a response to fishing pressure.

  • Description: Face-to-face adult communication with young people about sexuality is, for the most part, assigned to two main groups of people: educators tasked with teaching schoolbased sexuality education that is provided as part of the compulsory Life Orientation (LO) learning area, and parents. In this paper, we report on a study conducted with Further Education and Training College students in an Eastern Cape town. Using a discursive psychology lens, we analysed data from, first, a written question on what participants remember being taught about sexuality in LO classes and, second, focus group discussions held with mixed and same-sex groups. Discussions were structured around the sexualities of high school learners and the LO sexuality education that participants received at high school. We highlight participants’ common deployment of a ‘discourse of disconnect’ in their talk. In this discourse, the messages of ‘risk’ and ‘responsibility’ contained in adult face-to-face communications, by both parents and LO teachers, are depicted as being delivered through inadequate or nonrelational styles of communication, and as largely irrelevant to participants’ lives. Neither of these sources of communication was seen as understanding the realities of youth sexualities or as creating habitable or performable sexual subject positions. The dominance of this ‘discourse of disconnect’ has implications for how sexuality education and parent communication interventions are conducted.

A dynamic analysis of the influence of monetary policy on the general price level in Zimbabwe under periods of hyperinflation and dollarisation

  • Description: This thesis analyses the influence of monetary policy on the general price level in Zimbabwe during periods of hyperinflation and dollarisation. The first part of the analysis covers the period January 2006 to July 2008 when the country experienced high inflation and ultimately hyperinflation. The second part covers the period 2009 to 2012, when the country adopted the multi-currency system and became fully dollarised. In terms of motivation, the study firstly sought to empirically examine the factors that led to hyperinflation in Zimbabwe, paying particular attention to the influence of monetary policy. Secondly, the thesis sought to determine the major factors that influenced price formation in a dollarised Zimbabwean economy; a completely new macro-economic environment. A significant development in this new macro-economic environment was the loss of monetary policy autonomy of the central bank, which also contributed to the relevance of the study. This thesis makes two contributions. The first contribution is the finding that hyperinflation in Zimbabwe was caused by expansionary monetary policy as a result of the activities of an unrestrained and unaccountable central bank. The second contribution was the empirical finding that in the fully dollarised economy inflation is largely determined by external factors. This implies that the domestic economy has no control over domestic inflation developments and as such, Zimbabwean authorities should formulate appropriate economic policies to respond to the impact of external shocks on domestic price formation when the need arises. The role of monetary policy in Zimbabwe’s hyperinflation episode is assessed using the Autoregressive Distributed Lag (ARDL) and the Error Correction Model (ECM) approaches with monthly data from January 2006 to July 2008. The impact of monetary policy on hyperinflation is captured by the coefficient of broad money supply and the interest rate. Results indicate that hyperinflation was caused by expansionary monetary policy, the exchange rate premium and inflation expectations for both the short and long term. Zimbabwe’s hyperinflation episode which peaked during the period 2007 to 2008 brings to the fore the importance of ensuring that the central bank is independent in executing its mandate of influencing the monetary policy process in a manner that ensures price stability. The ARDL and ECM approaches are also used to explore the dynamics of inflation in the dollarised Zimbabwean economy, with monthly data from January 2009 to December 2012. The main drivers of inflation under the multi-currency system were found to be the United States of America dollar/South African rand exchange rate, international oil prices, inflation expectations and the South African inflation rate. The findings contrast with the hyperinflationary era, where empirical studies have cited excessive money supply growth as the major driver of inflation dynamics in Zimbabwe. The results also suggest a higher exchange rate pass-through to domestic prices, consistent with empirical literature which postulates that inflation in dollarised economies is largely explained by movements in the exchange rate of major trading partners and international prices. The policy implication from the analysis is the need for policy makers to aggressively promote policies that ensure increased productivity of the economy. An improvement in productivity would influence the relative prices of tradable and non-tradable goods and ultimately the general price level in the economy. The study also quantified the independence of the Reserve Bank of Zimbabwe (RBZ) using the Mathew (2006), “new index for institutional quality” and the results showed that the RBZ is not an independent central bank. The central bank is found to have a low index of central bank independence (CBI), against a high level of inflation. While this relationship does not imply causality it can be inferred that the lack of independence of the RBZ could have influenced inflation dynamics in Zimbabwe. Only a subordinated central bank can be compelled to engage in inflationary deficit financing and also fund quasi-fiscal activities. The provisions of the RBZ Act [Chapter 22:15] in their current form make the central bank an appendage of the Ministry of Finance and Economic Development and this has, to a large extent, resulted in conflict between the political goals of government and the central bank’s primary objective of achieving price stability. In the event that Zimbabwe reintroduces its own currency in future, the achievement of the primary goal of price stability by the central bank will only be realised if the apex bank is given more autonomy.

  • Description: Forested areas have been cited for their highly diverse floral and faunal assemblages, which are currently under threat from anthropogenic activities that restrict their range and deplete the resources produced within these naturally fragmented patches. Historically, up to 67 percent of avifaunal species associated with well-treed areas have undergone localised extinctions, consequentially affecting biodiversity as a measure of species richness and ecosystem functionality. To date, more than 900 of the bird species affiliated with forests are under threat and despite the theory surrounding functional redundancy, the mass extinction that is currently underway poses considerable limitations on the ecological integrity of these biomes. In South Africa, indigenous forest (one of the rarest biomes), occurs predominantly in small isolated patches along the eastern escarpment. With mountainous terrain emphasised as ‘prominent hotspots of extinction’, the limited dispersal and habitat sensitivity of montane forest fauna renders these species more prone to localised extinctions. BirdLife International, the IUCN and SABAP2 all indicate reductions in the range and abundance of the Chorister Robin-Chat (Cossypha dichroa) - an endemic forest specialist that is reported to move seasonally between high-altitude forest patches where they breed in summer, and lowland coastal forests where they overwinter. Beyond diet, body morphology and vocalisations, much of the information available on the altitudinal movements of C. dichroa is based on secondary sources and the assumptions therein. This study aimed to investigate the potential utilisation of δ13C and δ15N stable isotopes in determining the dietary niche width and altitudinal movements of C. dichroa. Feathers obtained in forested patches of the Limpopo, KwaZulu-Natal and Eastern Cape provinces exhibited a wide trophic niche width and generalised diet. Strong regional separation is apparent in the isotopic signatures suggesting little movement between provinces. A comparison of 13C-isotopes showed minimal variation that point to a uniformity in the carbon-base utilised by C. dichroa across their range. The 15N-signatures obtained in Limpopo, however, revealed a distinct trophic segregation between the northern-most Chorister populations and their southern counterparts. No altitudinal movements were detected in the isotopic signatures of recaptured Choristers, but more research is needed to investigate the long-term accuracy of these results and the breeding potential of resident Choristers in lowland coastal forests; especially when considering the reduced range and abundance reported for this endemic species.

  • Description: The changing business environment has increasingly driven organisations to incorporate sustainability into their corporate strategy for them to remain competitive. The economic, social and environmental goals and objectives of the organisation are now being factored into corporate strategy. This is as a result of the opportunities presented with the adoption of sustainability as a strategy and the threats caused by failure to adopt sustainability within their corporate strategy. For organisations to reap any benefits of incorporating sustainability, successful implementation of the strategy is needed. The role employees’ play in the implementation process of the sustainability strategy is critical. For successful implementation of the strategy, employee commitment is required as they have to adjust their actions and behaviours to be congruent with those required for the successful implementation of the sustainability strategy. However literature suggests that employees have received little attention in past research in regard to sustainability especially in emerging markets where research on sustainability has been limited. For this reason, the research problem for this study was how employee commitment can be improved towards the implementation of the sustainability strategy in their day-to-day operations. To achieve this objective, a conceptual framework was developed by investigating the organisational factors that impact on employee commitment to implementing sustainability in their day-to-day activities. To develop the conceptual framework, a literature review was conducted. The conceptual framework served as a basis for the construction of the questionnaire, to determine the nature of employee commitment to sustainability, to what extent they were implementing sustainability in their day-to-day activities and finally for the employees who were committed and were implementing sustainability what were the organisational factors that influenced their commitment to the sustainability strategy. The questionnaire was distributed to employees of different organisations in the Nelson Mandela Bay Metropolitan area who were MBA students at Nelson Mandela Metropolitan University. The findings of the empirical study indicate that the majority (75.5%) of the respondents were committed to all the tenets of sustainability, and were implementing the sustainability strategy. Though there were trade-offs in how the sustainability strategy was implemented, with the economic aspect having precedence where 84.5% of the respondents were implementing it, 70% of the respondents were implementing the social aspect of sustainability and 72.2% implementing the environmental tenet of sustainability. The organisational factors that influenced employee commitment to sustainability as was developed in the conceptual framework were all positively confirmed by the findings of the empirical study. Employee socialisation had the highest influence on commitment, followed by leadership, culture, communication, sustainability programmes and finally performance management. Formal and informal socialisation in the form of training and influence from experienced employees was the leading organisational factor that influenced commitment. The different roles top and middle management played in regard to sustainability followed. The organisational culture that existed in the organisation and the internal communication that was received all contributed to employee commitment to sustainability. The sustainability programmes in place and performance management systems in place were all organisational factors contributing to employee commitment to sustainability.

  • Description: Cloud computing adoption and usage is important to achieving business competition. This is done by making it a competitive tool for firms. The adoption of cloud computing enables firms to achieve greater business competency, improve performance, and allows them to maintain their competitive advantage. Since its emergence, there has been a surge in the adoption of cloud computing with research into its adoption primarily concentrated on bigger firms. However, a major characteristic of cloud computing is the anticipated possibilities it holds for small and medium-sized enterprises (SMEs). SMEs typically operate differently from larger firms and are not limited by resource constraints. For SMEs, the reduction in the financial burden normally associated with the adoption of new technologies is a significant benefit of cloud computing due to their financial constraints. In Ghana, SMEs mostly use obsolete technologies and have a slow response towards new technologies. Thus, they are unable to harness the numerous opportunities technology presents to them to stay competitive. Cloud computing is still regarded as a new technology in the business world, therefore research that focuses on its adoption by SMEs to help them stay competitive is minimal. Available research on cloud computing in Ghana does not provide clear guidelines for ensuring a successful adoption process and the continued use of cloud computing services. This study seeks to investigate how a framework can assist SMEs in their use of cloud computing in the Accra-Tema metropolis of Ghana. A knowledge of the factors associated with adoption decisions and those that significantly influence the decision are required to ensure a successful adoption process. The empirical data was gathered using a questionnaire and face-to-face interviews developed from literature and administered to users and potential users of cloud computing. The questionnaire and interviews primarily investigate key adoption factors and the findings are reported in this research study. The findings reveal interesting insights into understanding issues that affect the overall decision to adopt and use cloud computing services by SMEs. The findings show that the adoption of cloud computing can improve information management practices within SMEs. The findings also reveal that several factors need to be considered in the overall decision to adopt and use cloud computing to ensure a successful adoption process. An initial cloud computing adoption model was proposed based on the empirical findings. Key adoption factors of the initial adoption model include adoption benefits and drivers, concerns and barriers, adoption interventions, and information management in the cloud. computing adoption framework. The proposed adoption framework aims to assist SMEs to adopt and use cloud computing services and make them relevant in the global market.

The main research problem gave rise to six sub-problems that were addressed through the following actions: A literature study was conducted to explore what the existing literature revealed about facilitating successful expatriate integration. In particular, the theoretical guidelines for expatriate recruitment and selection, orientation and cross-cultural integration were presented and discussed. Special attention was given to community embeddedness. Semi-structured interviews were conducted with ten members from the sample group. These were undertaken to obtain their views on the expectations that their organisations had of them upon their arrival in Qatar, as well as on what they felt made it easy or difficult for them to adjust. Subsequently, a structured survey questionnaire was developed using the theoretical guidelines from the literature review and the insights gained from the semi-structured interviews. The survey was conducted in Qatar and administered to 102 skilled/professional self-initiated expatriates from diverse backgrounds and three work sectors, namely: healthcare, education and aviation. The final sample size was 94 due to eight questionnaires not being completed properly. The results from the empirical study revealed a gap between theoretical guidelines/ best practices and the recruitment and selection, orientation and cross-cultural integration practices at the respondents’ organisations. The knowledge gained from the existing literature and from the quantitative and qualitative results of the empirical study were combined and developed into a framework for the integration of skilled/professional self-initiated expatriates into Qatari organisations (refer to Table 5.35). Areas that were identified for improvement related to issues such as the need for Qatari organisations to: provide SIEs with more comprehensive information regarding the role that they will play as knowledge workers with regard to the development/training of Qatari nationals; implement a more comprehensive recruitment, selection and orientation process, and implement a more robust set of strategies to enhance the cross-cultural integration of their expatriate workers. Globalisation has fuelled organisations and countries towards building and/or strengthening knowledge-based economies. However in order to build competitive, knowledge-based economies, organisations and countries require skilled/professional workers. Skilled/professional self-initiated expatriates can provide Qatar with a pipeline of knowledge workers to support the growth of their emerging knowledge-based economy. As such, a framework that will enhance the integration of self-initiated expatriates into Qatari organisations is of paramount importance, specifically with regard to fostering performance excellence, satisfaction and community embeddedness within the Qatari work and cultural system.

  • Description: The proliferation of the Internet has amplified the use of social networking sites by creating a platform that encourages individuals to share information. As a result there is a wealth of information that is publically and easily accessible. This research explores whether open source intelligence (OSINT), which is freely available, could be used as a digital forensic investigative tool. A survey was created and sent to digital forensic investigators to establish whether they currently use OSINT when performing investigations. The survey results confirm that OSINT is being used by digital forensic investigators when performing investigations but there are currently no guidelines or frameworks available to support the use thereof. Additionally, the survey results showed a belief amongst those surveyed that evidence gleaned from OSINT sources is considered supplementary rather than evidentiary. The findings of this research led to the development of a framework that identifies and recommends key processes to follow when conducting OSINT investigations. The framework can assist digital forensic investigators to follow a structured and rigorous process, which may lead to the unanimous acceptance of information obtained via OSINT sources as evidentiary rather than supplementary in the near future.

  • Description: Supply chain management in the for-profit commercial environment is a broad, far-reaching field of study, impacting on a society’s standard of living. Commercial supply chain management is the science of balancing customer service levels with least total costs. In other words, the for-profit supply chain management practitioner is concerned with customer service levels, consumer value, shareholder value, total cost optimisation and ultimately maximising long term sustainable return on investment. Commercial supply chain management differs from military supply chain management in that the latter also focuses on service delivery, but the cost is almost irrelevant. In military operations, successful results (winning the battle) far surpass the total cost parameter or the return on investment. One of the major differentiating factors between commercial supply chain management (CSCM) in the for-profit theatre and humanitarian supply chain management (HSCM) in the not-for-profit supply environments hinges on strategic intent and how to measure success. In CSCM, return on investment (ROI) is key and in HSCM, the ability to create impact becomes paramount. Regarding spend, both CSCM and HSCM are concerned with optimising operational spend, optimal utilisation of capital goods and infrastructure as well as minimising the cost of goods, works and services. Commercial supply chain managers want to spend as little as possible on operational expenses similarly to their humanitarian counterparts but humanitarian supply chain managers are also concerned about underspending of donor funded programming. Humanitarian programming often happens under difficult and dangerous circumstances. This requires a special cadre of professionals who are willing to serve the most vulnerable without exploitation and are able to deliver value often with limited or even broken infrastructure, unreliable supply and under insecure conditions. Humanitarian supply chain management leadership requires a DBA thesis balanced approach between long term strategic views whilst managing the short term outcomes. Also, humanitarian leadership needs to balance decision-making between long term strategic interventions and the ability, maturity and cost structures at functional and executional levels. This conundrum is the fundamental difference between commercial supply chain management and humanitarian supply chain management. Once one understands and respects these nuances, one can measure performance and reward appropriate corrective behaviour. Zig Ziglar once said: “If you aim at nothing, you will hit it every time”. The question that has been asked for so long has been “how to measure supply chain management efficacy in humanitarian supply environments?” This study addresses this question of developing a framework to measure supply chain efficacy in humanitarian supply environments with the view to create an enabling environment within which service levels could enhance the impact of donor funding whilst the needs of intended beneficiaries are better served. During field research, ten key focus areas and sixty-five supply chain management elements were identified. These sixty-five elements were tested via two surveys making use of the Delphi technique. Four of the sixty-five SCM elements were eliminated following the second survey due to high disagreement between the respondents, and a further two were eliminated based on expert opinion feedback from the respondents leaving fifty-nine elements being significantly important for inclusion in the framework. Three additional elements were identified by the respondents but not empirically verified and therefore not included in the proposed frameworks but could be included in future research. Fifty-seven of the sixty-five elements can be directly controlled by the SCM function. However, four of these fifty-seven elements were eliminated during the second survey and a further two were eliminated reviewing the feedback from respondents leaving fifty-one elements under the direct control of the SCM function.

  • Description: [Partial abstract]: This study presents the first detailed geochemical and morphological characterisation of gold grains from the southern Seward Peninsula, Alaska, a region with significant historical and on-going placer gold mining. Quantitative Au, Ag, Hg, and Cu data are presented for gold grains from eleven sites. Additionally, quantitative Te, W, As, and Sb trace element data are presented for gold grains from ten of the eleven sites. Although it is acknowledged that quantitative trace element analysis of gold grains is a relatively new endeavour, the limited trace element data obtained in this study suggest that trace element analysis could be useful for characterising gold sources on the southern Seward Peninsula. Major and minor element geochemical profiling is sufficient at differentiating between sites from regional provenance systems but insufficient at differentiating between sites within a single system. Differentiating among sites within a single system will likely require microchemical analysis of mineral inclusions and analysis of trace element signatures.

  • Description: This study describes the bedrock lithologies and structure of the Ordovician to early Devonian (485-419 Ma) Table Mountain Group (TMG), the Devonian (419-358 Ma) lower Bokkeveld Group, and the Miocene to Holocene (<23 Ma) overburden sediments of the Algoa Group within an area identified by Eskom for the potential construction of South Africa’s second proposed nuclear power plant (NPP), ‘Nuclear-1’. The study area is located along the southern coastal margin of the Eastern Cape Province, South Africa, between Oyster Bay and St. Francis (approximately 88 km west of Port Elizabeth), and encompasses the Thyspunt site where the proposed NPP will be built. The study aims to supplement existing information about the Thyspunt area, related to the geoscientific topic ‘Geological Setting’, as outlined in section 2.5.1.1 of the US Nuclear Regulatory Commission (USNRC) Standard Review Plan NUREG-800, which details the geological information required for review of a proposed NPP. The results obtained from geoscientific studies are used to determine geological factors that may potentially affect site specific design. Factors considered include: bedrock lithology, stratigraphic bedrock contacts, bedrock palaeotopography, thickness of overburden sediments and structural geology. Work by previous authors is combined with new data to create a GIS based 2½D model of the study area’s geology (geomodel) and on which future research or interpretations can be based. Field mapping and petrographic analyses of the TMG, comprising the Peninsula, Cedarberg, Goudini, Skurweberg and Baviaanskloof Formations as well as the lower undifferentiated Bokkeveld Group were undertaken to define the study area’s lithologies and structure. Interpretation of geophysical results and the integration of existing borehole data aided in defining the variability in overburden sediments, the identification of contacts between TMG formations beneath overburden, and the palaeotopography of bedrock. Borehole data indicates a clear N-S trend in the thickness distribution of Algoa Group aeolian and marine related sediments. Four coast-parallel trending thickness zones (zones A – D) are recognized within the study area. At Thyspunt overburden thickness reaches a maximum of 61 m, approximately 1200 m from the coastline, in areas underlain by the argillaceous Goudini and Cedarberg Formations. Overburden thickness is influenced by a combination of dune relief, bedrock lithology, palaeotopography and the area’s sediment supply. Interpolation of bedrock elevation points and detailed cross sections across bedrock reveals four NW-SE trending palaeovalleys at Thyspunt, Tony’s Bay, Cape St. Francis and St. Francis, where bedrock relief (beneath overburden) is formed to be below present day sea-level. Approximately 450 m NW of Thys Bay, a 1050 m2 (area below sea-level) palaeovalley, gently sloping SE to a depth of -15.5 m asl, is cut into strata of the Goudini Formation resulting in thicker overburden fill in that area. Structural analysis of the TMG confirms that NE-SW striking strata form part of the regional SE plunging, north verging Cape St. Francis anticline. Bedding inclination is controlled by the distance away from the fold axis, varying from a 5° SE dip along the broad fold hinge to 65° along its moderately steeper SE limb. Folds within the study area plunge gently southeastward at shallow angles, with axial planes dipping steeply SW or NE. Fold axes orientated perpendicular to the fold axis of the Cape St. Francis anticline indicate a secondary stress orientation oblique to the main palaeostress direction. The previously identified 40 km long, NW-SE trending Cape St. Francis fault occurring offshore within 17.5 km of Thyspunt show no onshore continuation within the bounds of the study area. Late jointing is pervasive within the study area and four joint systems are identified. The dominant joint set J1, trends N-S to NNE - SSW; perpendicular to bedding and has a subvertical dip. Normal right-lateral and left-lateral micro-faults dip subvertically, with a displacement that ranges from a few centimetres to <3 m. Micro-faults trend parallel to joints sets J1 and J4 (ESE-WSW). Inferred faults, identified by the Atomic Energy Co-operation (AEC), are interpreted as zones of closely spaced jointing (shatter zones), and show little to no recognizable displacement. Faults and joints do not extend into the younger cover deposits of the Algoa Group and are therefore older than 23 Ma years.

  • Description: Thus Samuel Cron Cronwright-Schreiner in the "Preface" to his Life of Olive Schreiner (1924). Even at the remove of more than 90 years, these read as extremely strong claims. Volumes could be written about what Cronwright might/might not have meant by the "correctness" of his biography of his famous wife as well as the deconstruction of such loaded terms as "unusual personality" and "so complex and baffling a human being." Ten years after the publication of the Life, Cronwright (1934) himself unintentionally provided a further intriguing sense of what that "correctness" might in fact have concealed in the last letter he wrote to Havelock Ellis (10 Sept 1934, HRHRC).
