Production of and trade in African indigenous vegetables in the urban and peri-urban areas of Durban,South Africa

This paper reports on the farming and trade of lesser known crops, here termed African indigenous vegetables (AIVs), in the Durban metropole. Most households grow AIVs, and collect them from the wild, primarily for home consumption. Modal income from sale was approximately R30 per month per farmer, most of whom were middle-aged to elderly females, with limited education, who had been cultivating AIVs here for many years. The main constraints to greater sales were deemed to be low market demand and adverse climate. The commonest AIVs grown were pumpkin leaves, taro and amaranth. Although most farmers sold very little, there is a thriving retail trade in AIVs. Generally, retailers were females, but younger and more educated than the farmers. The majority viewed retailing as a full-time occupation. Modal income for retailers was R450 per month, but included non-AIV produce. Most of the traders thought there was insufficient market demand for AIVs.     

Purposeful Unintended Consequences with Innovative Derivatives

We suggest that the use of traditional market, outcome, and process controls for innovative derivatives trading may not provide adequate safeguards for clients, investors, or the entire financial system to control “purposeful unintended consequences.” We propose a more cautious examination of this aspect of the financial system using a combination of perspectives from finance and technology/innovation management. © 2001 John Wiley & Sons, Inc.     

Food choice and school meals: primary schoolchildren's perceptions of the healthiness of foods and the nutritional implications of food choices

Since the 1980 Education Act, school caterers have been operating within a commercial context and therefore can only provide the foods that they know that children will eat. At the same time, nutritionists have been concerned that the greater degree of choice that children now have at lunchtime is resulting in the more frequent consumption of meals of poor nutritional quality. A knowledge of children's food preferences, the factors influencing them, and their perceptions of the healthiness of foods is needed if school caterers and those involved in nutrition education are to work together to help children choose a nutritionally balanced meal. This paper reports on children's perceptions of the healthiness or otherwise of foods commonly served at school lunches and the reasons for these perceptions. Children's knowledge of the sources of nutrients, their understanding of the relationship between food and health, and how their perceptions of healthiness relate to their preferences for the foods are also explored. The nutritional implications of food choices made by primary school children on the basis of preference rather than healthiness are examined. One hundred and twenty three children aged between nine and eleven from 14 different primary schools in SouthEast England took part. Using photographs of foods commonly served at school lunches, the children were asked to rank the foods in order of preference and then according to their perceptions of the healthiness of the foods and give their reasons in each case. The rankings were analysed numerically and the Wilcoxon's pairs signed rank test was used to determine the significance of the difference. The qualitative data on the reasons given for the rankings were analysed by assigning them to categories. The children were also asked which foods they would choose for the meal that they would be most likely to eat, and which ones for the meal that they thought would be the most healthy. The nutritional value of the two sets of meals were determined and compared. A student T- test was used to determine the significance of any difference between the two sets of meals.It was found that the children had a clear perception of the healthiness or otherwise of the foods. However, understanding of the relationship between foods or nutrients and health was only occasionally evident, as was the idea of moderation or balance. Some children perceived healthiness as the absence of fat while others saw it in terms of the presence of vitamins. It was also found that there was a strongly inverse relationship between children's perceptions of the healthiness of foods and their preferences for them. It was found that while the foods chosen for the ‘healthy’ meal were chosen least frequently for the ‘preferred’ meal, there was no significant difference between the percentage of energy provided by fat in the two sets of meals. However the ‘preferred’ meals did in fact provide a significantly higher percentage of the energy as starch, as well as containing greater amounts of some micronutrients. In other respects the ‘healthy’ meals were indeed ‘healthier’, in that they provided greater amounts per megajoule of some important nutrients.It was concluded that teaching about food in primary schools needs to focus on helping children of this age make balanced food choices. It was suggested that the ‘tilted plate’ model, adapted to use foods that children frequently eat and enjoy, could be the basis of such teaching. Such a model could also be used to help caterers plan menus and as the basis of co-operation between nutrition educators and caterers.     

Fiscal Stabilisation and EMU

This paper builds on the papers published by HM Treasury in2003 alongside the UK Government's assessment of the case forEMU entry. The paper considers the potential for fiscal policyto play a greater role in stabilisation policy if the UK wereinside EMU. The paper considers: the scope for strengtheningthe automatic stabilisers and the possible trade-offs; how institutionalchanges could increase the effectiveness of discretionary fiscalpolicy; which fiscal instruments might be most effective; andto what extent stabilisation might be promoted in other ways,such as through enhanced risk sharing by financial markets.(JEL E62, E63)     

Managing the Risks Associated with Using Biomedical Ethics Advice

This paper discusses the criticisms that exist about corporate use of ethics advice by bioscience companies and offers suggestions on how ethics advisors can be used so as to maximize their utility and avoid the criticism.     

Hotel management style: a study of employee perceptions and preferences

This study investigates employee perceptions of, and preferences for, management practices within a five-star, medium-sized hotel. In particular, the study examines the hypothesis that hotel managers have become more consultative. Using longitudinal data over a 4-yr period, the study examines the perceptions of staff of the management practices and styles in the changing environment of one hotel. The findings suggest that, while staff prefer a decisive style of management, supervisors and department heads were perceived as being autocratic. In fact, in the 4 yr over which the data had been collected, the style of management had become less consultative and more autocratic. Implications for management are discussed, as are recommendations for future research.     

A preliminary assessment of the function and conference service product at a UK stately home

The UK conference market is estimated to be worth £6 billion and is thought to be the fastest growing sector of the hotel industry. An increasing number of less conventional venues are aiming to attract corporate business, though most empirical research focuses on the hotel conference product. A UK stately home is the venue studied in this article. To identify possible areas for improvement, a telephone survey of customers was undertaken to assess the service and facilities. The high average ratings indicate that generally organisers have a favourable impression of the stately home. The research revealed significant differences in the average ratings given for the Main Hall and His Lordship's Apartment, the two rooms available for functions. Event category and organiser experience were not found to influence the ratings. Due to the relatively small sample size, only tentative observations are made about the trends which emerged from the analysis.     

Potential problem analysis: A systematic approach to problem prediction and contingency planning—an aid to the smooth exploitation of research

Scientists and technologists have always attempted to predict ‘what is likely to go wrong’ with a particular project. At URL Colworth/Welwyn we now have some 24 years’ experience in a semi-formalized system of problem prediction. The paper describes the system, explains its worth and shows where and when it should be used as well as explaining the consequences of its use. A theoretical justification of some of the assumptions used in the system is also attempted.
