The Impact

This study sought to evaluate the impact of the Indigenisation Policy on the socio-economic emancipation of rural communities in Zimbabwe. A case study approach was taken focusing on the Marange and Zimunya communities in Manicaland Province of Zimbabwe, where diamonds are being mined. Both qualitative and quantitative research methodologies were applied to get a balanced view from these two communities on their socio-economic improvement because of the mining of diamonds, which are a valuable natural resource found in these two communities. Purposive sampling was applied to come up with the sample of senior politicians and traditional leaders. Two Focus groups were formed in the two communities. The study established that the five diamond mining companies doing business in the two communities had failed to honour their pledges of contributing USD10 million each towards the development of the two communities. Only USD400 000 was contributed by two mining companies at the time of the study. Ninety five percent (95%) of the respondents reported that there were no projects that were being implemented to benefit the local communities. It was therefore, concluded that there was limited socio-economic empowerment of the Marange-Zimunya communities by the diamond mining companies. The study recommended the intervention by the Government in order for these mining companies to honour their pledges by coming up with empowerment projects and also by allowing the two communities to have shares in these companies so that they could be economically empowered.

Mining Scheme

Diamonds were discovered in Sierra Leone in 1930, and in 1934 sole mining rights were granted to the Sierra Leone Selection Trust (SLST), a subsidiary of the London-based Consolidated African Selection Trust, part of De Beers empire. In 1956, partly to restrict the increasingly prevalent illicit mining, and partly for political reasons, SLST opened part of its lease to mining by licensed miners under the Alluvial Diamond Mining Scheme (ADMS). The Sierra Leone government took over 51 per cent of the SLST shares in 1970, and a new company, the National Diamond Mining Company (NDMC), was formed. In 1980 SLST sold out to British Petroleum and left Sierra Leone.

The Relationship

This paper studies the relationship between civil war and the value of firms in a poor, resource-abundant country using microeconomic data for Angola. We focus on diamond mining firms and conduct an event study on the sudden end of the conflict, marked by the death of the rebel movement leader in 2002. We find that the stock market perceived this event as “bad news” rather than “good news” for companies holding concessions in Angola, as their abnormal returns declined by 4 percentage points. The event had no effect on a control portfolio of otherwise similar diamond mining companies. This finding is corroborated by other events and by the adoption of alternative methodologies. We interpret our findings in light of conflict-generated entry barriers, government bargaining power, and transparency in the licensing process. (JEL D74, G32, O13, O17, Q34)

Basic English

This article tells the story of the eccentric and unknown writer Albert William Alderson (1880–1963), a British South African office clerk whose father had helped found the De Beers diamond mining corporation with Cecil Rhodes. Alderson, despite having no academic background, wrote two books and several pamphlets arguing that world peace could be achieved by eliminating all the languages in the world other than English; he buttressed this claim with an elaborate account of the causes of war taken from his reading in world history, but also with extraordinary statements on the relation of language to personal agency. Although Alderson's arguments cannot be taken seriously, they are illuminating as an example of “naïve” liberalism pushed to its limit; that is, as a case-study in heterodoxy comparable to Carlo Ginzburg's Menocchio. I conclude by suggesting that his work helped inspire one influential reader—C. K. Ogden, the founder of Basic English.

In practice, the difference between the actual and planned costs forthe maintenance of slurry pumps used at concentration and screening plants of Russian diamond mining companies is mainly represented by the costs of purchase and delivery of their new original (OEM) parts. These costs are primarily due to the premature failure of pump components. The impeller is the least reliable or fail-proof element in their design. The main cause for impeller failure is the intense abrasion of its surfaces by mechanical impurities contained in the slurry pumped. The respective comprehensive scientific research has established the critical factors affecting the weighted average service life of pump impellers used by Russian diamond mining companies. A linear regression model has also been designed, allowing to predict the service life of impellers in Russian-made slurry pumps for the processing plants of PJSC ALROSA with a high degree of probability, duly confirmed using the Fisher criterion. The results obtained are of great practical interest as they make it possible to further assess impeller operational durability and to accordingly predict the maintenance costs for the slurry pumps, depending on their specific operation conditions at Russian diamond mining companies.

And Performance

In this article, Dr. Newbury focuses on the technical and financial reasons for amalgamation at the Kimberley mines in South Africa, drawing on primary records to account for the rise of De Beers as the world's major diamond mining company in the 1880s. He finds that prior experience in local government and on the mining boards prepared company directors for competition in joint stock enterprise, while differences in production policies and performance influenced the pattern of mergers within and among the four Kimberley mines. De Beers's close relationship with diamond merchants and private banks in London, particularly N. M. Rothschild & Sons, was central to its position as a prime mover toward consolidation. Dr. Newbury views De Beers as a firm that relied for its success less on its renowned chairman, Cecil J. Rhodes, than on a combined managerial expertise that reflected the interests of both mining producers and merchant buyers.
