An appropriate model for joint regional action in southern Africa after apartheid

Market‐based integration is not appropriate to the joint development of the southern African region; the region's political, technical and institutional immaturity requires instead loose, function‐based economic cooperation. This will also facilitate intraregional trade. Subregions in the meantime could progress to higher levels of integration: international experience has shown that successful integration is most likely when it takes place on the basis of ‘regions within regions’. Cooperative development of the subcontinent is likely to be best achieved through the ‘concentric circles’ approach to regional cooperation, in which a revised Southern African Customs Union‐Common Monetary Area forms the highly integrated core of a loose, function‐based cooperative arrangement covering the whole of southern Africa.     

STUDIES OF MANAGERIAL JOBS AND BEHAVIOUR: THE WAYS FORWARD

The main achievements and limitations of studies of managerial jobs and behaviour are summarized drawing upon the review articles of Martinko and Gardner (1985) and Hales (1986). Ways forward are explored by developing a map of the field for future studies, which is shown in figure 1. The figure has three aims: to show different areas for research; to help in identifying neglected areas that could be fruitful ways forward; and to show the interrelationship between different aspects of the study and thus to act as a guide for data collection. The main purpose of the article is to be a guide to what can, and what might most fruitfully, be studied, but some suggestions are also made about methods.     

The Self-concept of Black and White Women: The Influences Upon Its Formation of Welfare Dependency, Work Effort, Family Networks, and Illnesses

Abstract . The concept of “self-efficacy” is used to test the hypothesis that the negative self-concept of welfare recipients coniributes to long term psychological and material dependency on such assistance. Self-efficacy focuses on the extent to which people are able to produce and regulate events in their lives and is associated with self-imposed performance expectations. The extent to which the minority status which Blacks occupy in this society decreases self efficacy relative to Whites is examined, using information generated from structured interviews with 290 low income Black and White women. Operationalizing the concept of self-efficacy with appropriate controls for socioeconomic status, family composition and other factors results in finding no racial differences in sense of self-efficacy between Black and White women. Observed differences in patterns of receipt of public assistance are found to be more directly related to the persistence of structural barriers to upward mobility that have differential impacts on Blacks and Whites. Long term receipt of public assistance is found to adversely affect both self-worth and work orientation/perceived efficacy for all women.

Using choice experiments to value catchment and estuary health in Tasmania with individual preference heterogeneity*

Choice experiments (CE) have become widespread as an approach to environmental valuation in both Australia and overseas. However, there are few valuation studies that have addressed natural resource management (NRM) changes in Tasmania. Furthermore, few studies have focussed on the estimation of estuary values. The CE study described in this paper aims to analyse community preferences for NRM options in the George catchment, Tasmania. Catchment health attributes were: the length of native riverside vegetation; the number of rare native animal and plant species in the George catchment; and area of healthy seagrass beds in the Georges Bay, which was used as a measure of estuary condition. Mixed logit models with interactions between socio‐economic variables and the choice attributes were estimated to account for systematic and random taste heterogeneity across respondents. Results reveal considerable variation in preferences towards the attributes and show that value estimates are significantly impacted by the way in which we account for preference heterogeneity. Preference heterogeneity thus needs to be considered when estimating community willingness‐to‐pay for environmental changes. This study further shows little responsiveness to the presented changes in estuary seagrass area.     

The Human Development Approach: An Overview

The human development (HD) approach puts the improvement of people’s lives as the central objective of development. This paper provides an overview of major aspects of the approach. It shows how it emerged with the evolution of development thought and a widening of development objectives The paper explores the two-way relationship between HD and the rival objective, economic growth, is explored and broad characteristics of countries that have been exceptionally successful or unsuccessful , countries with three country cases considered in greater depth. The paper identifies major dimensions of HD, beyond the three elements included in the Human Development Index (HDI) and shows they are poorly captured by the HDI. An overview of global change on HD dimensions from 1980 to 2015 gives a mixed picture with progress on basic HD, uneven trends in some areas, and notable worsening on the environmental dimension. In conclusion, the paper discusses some outstanding issues which need more attention.
