Abstract. In this article, the relationship between individual productivity in research, as measured by an index of publications produced, and their preferences and perceptions about research-related issues is explored. A sample of t34 Australian university economists were classified as low, average and high in respect of their publication performance using cluster analysis. Discriminant analysis was then used to see whether membership of these groups was associated with items representing individuals' preferred research approach, their involvement in a range of research-related activities, the things which they felt constrained their research and their perceptions of the benefits of their position which might be conducive to research.Our results show that there was a relationship between these items and group membership, and therefore productivity. Highly productive researchers made deliberate choices about the type of research they undertook in order to enhance their career advancement; they were heavily involved in a number of areas of research activity; they felt relatively few constraints on their research by comparison with low producers; and they enjoyed the freedom and challenge of their positions. These results imply that research performance is more a function of individual motivation than resource support.

The district hospitals are an integral part of the district health system (DHS) in South Africa fulfilling several important functions. Using data obtained from relevant published reports. The district hospital costs were allocated using the ‘ingredients approach’ that combined a top-down method and step-down sequence. The costs in the treatment of patients were grouped into six cost centres: buildings, drugs, equipment, materials, personnel and utilities. The unit costs were broadly grouped into two categories using the hospital departments (fixed and variable costs) and input use (direct and indirect costs). More than 30% of the total public expenditure on hospitals in the country was on district hospitals between 1996/97 and 1998/99. They had more beds per population (1.08/1000) than other public hospitals. The bed occupancy rates in these hospitals were generally very low varying between 57% and 75%. The average length of stay (ALOS) was within acceptable range in the hospital except in Osindisweni hospital. Personnel costs were more than 70% and drugs only 3% to 6% of the total costs. McCord hospital was the most expensive using total and unit costs. Harrismith hospital had the lowest total costs and Osindisweni hospital the lowest unit cost. Most of the costs were fixed or direct costs in all the hospitals. There is the need for the adoption of measures to ensure that the hospitals are efficiently run while maintaining access for vulnerable groups.

Thirty two studies of the impact of HIV/AIDS on households conducted over the last decade were reviewed. The direct and indirect costs of HIV/AIDS to households increase with severity of illness and ultimately death. HIV/AIDS morbidity and mortality affect household income and expenditure patterns. Households employ various survival strategies to alleviate loss of labour and income, survive the financial cost and optimise the use of safety networks. Various gaps were found in the literature, which future studies could explore. Household surveys should be multi-disciplinary and longitudinal in nature so that the full impact of HIV/AIDS could be assessed over time. Copyright 2005 Economic Society of South Africa.
