Chibuluma Mine is situated on the southern flank of the Nkana-Chambishi basin in the central section of the Zambian Copperbelt. The amphibolite at Chibuluma Mine occurs exclusively in the Upper Roan Group sediments overlying the economically important Lower Roan Group. The amphibolite occurs in lenticular, sill-like bodies ranging in thickness from less than 10 feet to over 1,000 feet. It is concluded that these sill-like bodies are intrusive sills of basic magma. The largest sill is a multiple intrusion with two phases, both of which exhibit chilled margins. The younger phase was intruded into the older along a plane approximately 50 feet above its basal contact. Grainsize, specific gravity, and micrometric data indicate that each phase of the intrusion has undergone gravitational differentiation during crystallisation. Variations in the relative amounts of amphibole and feldspar distinguish between a lower melanocratic amphibolite, an upper mesotype amphibolite, and a zone of coarse-grained pegmatitic amphibolite schlieren. The amphibolite consists mainly of hornblende, labradorite, albite, and scapolite, with accessory biotite, chlorite, epidote, clinozoisite, sphene, apatite, quartz, micropegmatite, and calcite. Clouding of the basic plagioclase and zoning in amphibole, plagioclase, and scapolite are features of petrological significance. The opaque minerals in the amphibolites and the adjacent sediments are magnetite, ilmenite, pyrite, chalcopyrite, pyrrhotite, cubanite, valleriite, and pentlandite. Intergrowths of these suggest that their temperatures of formation were probably in excess of 450°C. The chemical data show a close resemblance between the amphibolite and a tholeiitic magma-type although minor spilitic characteristics are also evident. The chemical data also confirm the mineralogical evidence of fractionation and gravitational differentiation. The trend in differentiation followed in the development of the pegmatitic and mesotype amphibolite is very similar to the trends followed by other basic intrusions. The main metamorphic affect accompanying the intrusion of the amphibolite is the soda metasomatism evident in both sediments and intrusions. Some evidence exists to suggest that the amphibolites were emplaced before or during the early stages of the Lufilian orogeny when sediments were essentially horizontal.

The aim of this study has been to explain the relationship between capital (development) expenditures and the growth of recurrent expenditures in the Zambian Ministry of Agriculture and Water Development (1975-1983). Three models were developed and tested. The first model tested the theory of incrementalism. Proponents of incrementalism advocate that the recurrent budget in a previous period is the most important explanatory variable in the determination of recurrent budget expenditures in the subsequent period. An extension on the first model included capital expenditures in the determination of recurrent budget expenditures. Theories have been advanced that capital expenditures cannot be undertaken without affecting the growth of recurrent expenditures. A third explanatory model included the stock of capital, the recurrent budget in the previous period, the rate of inflation, and the lagged price of copper as important variables in the determination of recurrent budget expenditures. Ordinary least squares (0LS) estimation techniques were used to obtain the coefficients and the magnitude of the variables in these three models. The third model explained 98% of the variation in recurrent budget expenditures. The results showed that the recurrent budget in the previous period and the rate of inflation were the most important explanatory variables in the determination of the recurrent budgets in Zambia. The price of copper and the stock of capital, although both having a positive relationship with the recurrent budget in the subsequent period, were weak determinants. The study noted that the weak relationship between the capital and recurrent budget may be due to the ad hoc transference of recurrent costs, created by capital projects, to the recurrent budget. The study suggests a policy for the transference of these costs to the recurrent budget. / Land and Food Systems, Faculty of / Graduate

A research report submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, South Africa, in partial fulfilment of the requirements for the award of the of Masters of Arts Degree in Labour and Development, Economic Policy, Globalisation and Labour (Labour Policy and Globalisation). Johannesburg, 2016 / Zambia has been implementing economic liberalisation policies at the advice of the IMF and the World Bank, to reverse years of economic decline that began with the commodity crisis of the 1970s. As a strategy for economic growth, these included, the deregulation of foreign investment, removal of currency controls, trade liberalisation, decontrolling prices, cutting food subsidies, reduction of state control in running the economy and privatization of state run companies. The rapid implementation of these measures by the Zambian government has seen a change in employment trends in the mining industry from permanent employment to casualisation of labour.These measures have resulted into negative social and economicconsequences on the lives of the casualised mine workers such as job insecurity, poor health and safety standards, lack of protection and union representation, poor remuneration, lack of pension,and other forms of exploitation. Despite booms and busts in the copper price, employment levels have been drastically dropping especially among the permanent mine workers as a cost cutting measure. The role of the state in the running of the mines which Zambia has depended on since independence has diminished significantly and the state is increasingly succumbing to the dictates of the mining Trans-National Corporations (TNCs).The study which was conducted among casualised/contract rock ore drillers at Mopani Copper Mines Plc reaffirms arguments by previous researchers that economic liberalisation has not achieved the high expectations that Zambians wished for and that there is need for government and trade unions to protect the welfare and working conditions of these casualised mine workers who have become a new set of underclass. Through in-depth interviews, observations and documentary analysis, this research has brought to light the social and economic experiences of casualised/contract rock ore drillers at Mopani Copper Mines Plc and questions whether Zambian mine workers were better off when the mines were being run by the state than is currently the case under TNCs. / MT2017

The focus of this study was on common psychiatric comorbidities of depression and anxiety in people with epilepsy (PWE). While international published data show that up to 60% of PWE suffer from depression and/or anxiety, most primary care (PHC) settings in developed countries display some oversight in this area. The study was conducted in Zambia, in three phases; which each culminated in submissions for publication in an internationally peer reviewed journal. Phase one involved chart review to establish the rate of detection of depression and/or anxiety in PWE at the outpatient clinic of Chainama Hills College Hospital. The detection rate was only 1%. This formed the basis for phase two where we developed a ten item screening tool for depression and/or anxiety for use by PHC workers in busy clinical settings. The tool was validated, its sensitivity and specificity were determined and the inter-rater reliability was also calculated. Phase three involved implementation of the tool validated screening tool. We measured the ability of PHC workers to use and interpret the screening tool in busy clinical settings. One month after training and implementing the use of the screening tool, a retrospective chart review was undertaken using the same tool that was employed in phase one chart review. There was a marked improvement when 120 files of PWE were reviewed as the percentage of screening for depression and anxiety increased from 1% to 49%. / Theses (Ph.D.)-University of KwaZulu-Natal, Durban, 2014.

Normative professional journalism and the need to re-evaluate the structural social context of journalism practice and its role in emerging democracies has led to the increased scrutiny of journalists and their relationship to news sources. This study conceptualises the relationship between journalists and news sources as a dual process of consensus and conflict of interests in the newsgathering practice in Zambia, an emerging democracy. The study suggests that journalists actively pursue powerful individuals in society such as those in government, pressure groups and business as news sources who have been available and suitable in the past. Journalists’ view of society as bureaucratically organised and the short turn-around time of news production are among the organisational factors attributed to this tendency. This study adopts a sociological approach to investigate the journalist-news source relationship at The Post, in Zambia, by factoring in the perspectives of social organisation of newswork and political economy. Whereas the social organisation perspective focuses on the organisational and occupational demands of journalists, political economy reinforces the larger context of journalist-news source interaction in a society. Additionally, the social constructivist theory, which is premised around the idea that the agenda and content of journalism production, is in part a product of non-journalistic social factors is useful in understanding the various influences on the relationship. The study investigates the nature of the journalist-news source relationship using two diametrically opposed views – the dominant (exchange) and competitive (adversarial) paradigms. This is aimed at establishing whether the relationship is an exchange or adversarial. While the latter relationship is common in liberal democracies where the media are seen as part of elite structures with considerable power on their own, the thinking is that inequalities in resource distribution and political power generate social tensions in developing countries that require media to be carefully managed. Using qualitative semi-structured interviews and observation methods, this study establishes that while the adversarial role has an attraction for the journalists investigated, the exchange model comes closest to describing the nature of relationship they share with their news sources.
