This paper examines the contribution of three aggregate mining sectors of the South African economy to output and employment over the 1970-97 period. The finding of a declining importance of mining in output and employment creation must be sectorally differentiated. Gold and Uranium Mining is the chief source of these declines, while evidence for Coal and Diamond and Other Mining is more modulated. We find strong redistribution of output from equity to labour over the course of the 1990s for Gold and Uranium Mining. In mining labour markets, we present developments in employment trends, in real labour cost, and in labour productivity. We examine links between these dimensions in an explanation of changing employment trends. We conclude with a VECM estimation of a labour requirements equation to corroborate our findings.

People in almost any occupation could develop burnout. The objective of this research was to determine the relationship between sense of coherence, coping and burnout in a corporate pharmacy group. A cross-sectional survey design was used. The study population consisted of 67 pharmacists. The Maslach Burnout Inventory, Orientation to Life Questionnaire and COPE were administered. The results showed that sense of coherence is significantly related to emotional exhaustion, depersonalisation and personal accomplishment. Regarding coping strategies, mental disengagement was positively related to emotional exhaustion and depersonalisation, while positive reinterpretation and restraint coping were positively related to personal accomplishment. Sense of coherence and coping strategies explained 44 per cent, 35 per cent and 41 per cent of the variance in emotional exhaustion, depersonalisation and personal accomplishment respectively.

Food output in Nigeria has deteriorated since the 1970s, whereas the population continues to grow. Consequently, the country experiences a fall in per capita food production. Grouping the country's food producers under four categories, this paper argues that production has remained a predominantly peasant affair, characterized by subsistency, inefficiency and low productivity. For a way forward out of the food crises, we introduce a theoretical model of the impact of policy mechanisms on agricultural output. We also look at the target group of the policy mechanisms. The paper concludes that to tackle the food crises, the country needs a radical approach to the problem, with emphasis on a total departure from its hitherto subsistence farming to a modern commercial farming.

This study is concerned with devising short-term switching strategies to capitalize on abnormal return opportunities by examining the interaction between style action and market phase. Thus it seeks to determine whether styles do better under different market conditions. A total of 288 stocks from five ASEAN countries over an eight-year period comprising four distinct market segments are considered. Market phases are distinguished by recursive regression estimation while the portfolios are scored by use of a mean variance/ tracking-error methodology. The statistical significance of the performance of each individual style, so rated, is investigated parametrically. The study concludes that value reigns under most market conditions, except for the early bull period where growth investing is superior.

Despite the increase in the number of women participating in the South African labour market in recent years, little progress has been made in removing wage disparities, eradicating women's marginality in the labour market, reassessing women's work or changing the traditional occupational ghettos of women. Not only does the South African labour market exhibit anomalies in respect of the gender composition of occupations, there are substantial differences by race. A good barometer of determining the extent, to which men and women undertake different types of jobs, is to analyse the percentage of male and female workers per occupational category.
Steering in uncertain territory: E-business, globalisation and the South African automotive components industryAuthor Sagren MoodleySource: South African Journal of Economic and Management Sciences 5, pp 123 –153 (2002)More Less
Significant and sustainable growth of the South African automotive components industry is contingent upon its ability to compete in a global, e-business-enabled operating environment. The key challenge facing the South African automotive component industry today is one of connectedness to global trade networks, the generation of export volumes and industrial upgrading in global-scale value chains. The domestic components industry will need to leverage e-business for supply chain management and to take part in global trade networks, thus making it urgent for firms to develop IT capabilities. By not making the transition to e-business, component firms may be placing themselves at risk of becoming less competitive in the globally interconnected market, impacting on both their current market positions and long-term viability. If this were to happen, it would have adverse development implications for the country, such as job losses, a decline in revenue growth and an eroded export base.

The aim of the study was to identify the personality traits, emotive responses and attitudinal orientation of franchisees. Cattell's 16 Personality Factor Questionnaire, the Personal Profile Analysis of Thomas International and Boshoff's Entrepreneurial Attitude Questionnaire were used. Measurements were obtained in respect of a sample of 80 restaurants belonging to a fast foods franchise. A stepwise discriminant analysis identified statistically significant differences between successful and unsuccessful groups in respect of five factors. Successful franchisees were emotionally more stable and sober minded, exhibited a higher degree of shrewdness, displayed higher self-esteem, and were more compliant. The Jack-Knife Classification was used in devising a classification table to compare the observed and predicted success rates of franchisees. The study found that the identified five factors could be used to predict the potential success rate of franchisees.

Over the next ten years, as the AIDS epidemic takes its toll on the economically active population, employers will incur considerable costs. However, relatively inexpensive interventions, if implemented now, can yield substantial returns and save business considerable amounts of money. Thus, social responsibility can be argued to make economic sense. Worrying, though, is that there also appears to be a general apathy on the part of business, especially amongst small and medium-sized enterprises. A lot needs to be done to change the attitude of business and get business actively involved in the fight against HIV/AIDS. The private sector can and need to do its share in an integrated, coordinated response to HIV/AIDS, thus contributing to the initiatives on which the government, NGOs and communities have already embarked.

African countries considered in this study face many supply constraints and so lack the capacity to produce. Export promotion effort cannot be successful unless such constraints are removed. Transparency in governance, improvements in basic infrastructure and economic liberalization are some of the ways to remove such constraints. Direct private investment to accelerate economic expansion rather than exchange rate manipulations are needed before export promotion policy can be successful.

The urgent need to develop South Africa's human resources in the public service has been conceptualized in many policy documents. The underlying objective of efforts to strengthen the human resources in the public sector is the delivery of effective services to the people of South Africa. In line with the White Paper on the Transformation of the Public Service, 1995, the effective mobilization, development and utilization of human resources are stressed as important factors in the transformation of the public service because of their contribution to individual and institutional capacity to ensure effective governance. Financial resources are important in order to develop and sustain the skills of the public servants; however, there is a tendency to cut the budget for human resource development programmes. Alternative methods should be developed to obtain additional sources of income.

Inadequate market segmentation and clustering problems could cause an enterprise to either miss a strategic marketing opportunity or not cash in on a tactical campaign. The need for in-depth knowledge of customer segments and to overcome the limitations of non-linear problems requires a different approach. The objectives of the research are (l) to consider the use of self-organising feature (SOM) neural networks for segmenting tourist markets and (2) to assess the use of inducing decision trees to obtain rules for profiling existing and classifying new respondents. The findings of the SOM neural network modelling indicate three definitive natural clusters. The induction of rules from decision trees were used to obtain a broad indication of a segment profile on the basis of a rule set and also enables the segment classification of customers from follow-up surveys.

The Thomas Killman Conflict Mode Instrument is widely used to assess conflict management styles. The instrument uses two parameters, i.e. assertiveness and cooperation, resulting in five distinct styles: avoiding, competing, collaborating, accommodating and compromising. Twenty five senior- and twenty five junior managers in the banking industry (2 particular companies) completed the questionnaire, answering in the context of their relationships with each other. Results indicate significant differences between the two groups. Senior management prefers the assertive styles (competing and collaborating) with scant attention to cooperation, while middle management primarily uses the avoiding style, which is both uncooperative and unassertive. The implications of these findings are discussed, leading to particular recommendations.
