The Relationship between Subjective Well-being and Domain Satisfactions in South Africa

This paper examines the relationship between subjective well-being and domain satisfactions. In the past different models have been specified. The most commonly applied model is the bottom-up model in which domain satisfactions affect subjective well-being. The more recent top-down model suggests a reversed relationship. Finally there is the supposition that the correlations between these variables can be spurious due to the effect of personality characteristics. Empirical research has shown that different models are found for different domains and in different countries. Focussing on the effects of the domain satisfactions of finances, housing and social contacts it has been found that subjective well-being is mainly affected by satisfaction with social contacts in Western developed countries and by satisfaction with finances in East European countries. The question we should like to answer in this study is whether a similar pattern obtains for the factors which influence subjective well-being among the different race groups in South Africa. Interestingly, coloured people and Asians did indeed show the expected effects but the groups with the most extreme living conditions did not. Evaluation of life circumstances by black and white South Africans was determined by expectations for the future rather than by current living conditions. This surprising result is discussed in the light of the political situation in South Africa.     

Mangrove forests store high densities of carbon across the tropical urban landscape of Singapore

Tropical forested ecosystems provide multiple ecosystem services to rural and urban landscapes, with carbon storage gaining particular attention. Deforestation due to rural-urban transitions may lead to a reduction in carbon storage ability. Coastal mangrove forests are particularly at risk from deforestation due to their location in the rapidly urbanizing coastal zone, and the city state of Singapore is an extreme example, losing as much as 90 % of its original mangrove cover due to land reclamation and reservoir construction. Knowledge of mangrove ecosystem services may allow better conservation, restoration and incorporation of remaining mangrove patches into the urban landscape. Focusing on the regulating ecosystem service of carbon storage, mangrove carbon stocks have been estimated for Singapore using a combination of field and remote sensing techniques. Biomass carbon showed substantial spatial variation, with old, contiguous mangrove patches containing a higher density of biomass carbon than fragmented, river-fringing or restored mangroves. In total, national biomass carbon equated to 116,117.1 megagrams of carbon (Mg C), and a coarse estimate of the total carbon stock (including soil carbon) suggests that Singapore’s mangroves may store 450,571.7 Mg C. While lower than other regional estimates focused on natural, oceanic mangroves, this is a significant carbon stock for a disturbed, urban mangrove system, and may be equivalent to the average annual carbon emissions of 621,000 residents. This analysis, alongside a review of other urban forest studies, highlights the importance of forested ecosystems such as mangroves in providing a carbon storage ecosystem service to urban areas.     

Managing Corporate Knowledge Experiences with SODA and V·I·S·A

It is often said that success in today's competitive environment depends on the acquisition and application of sound, relevant knowledge. This paper introduces two management science approaches that have been used for the effective management of knowledge, towards the development of strategy, planning and decision making, in a wide range of organizational settings. Both approaches make use of computer technology to provide a flexible and interactive environment incorporating a visual representation of the problem. The paper briefly describes each approach, together with a case study illustrating its use in practice. A number of common themes relevant to the management of knowledge are identified and discussed. The themes highlight the benefits which arise through the use of computer technology alongside a number of issues relevant to the management of the group process.     

State lotteries and compulsive gambling

The legalization of gambling, including state lotteries, has resulted in a dramatic increase of compulsive gambling. Not surprisingly, a new profile of compulsive gambler has emerged which differs significantly from the previous profile of white, middle aged, middle class male. This paper discusses public policy issues, lottery advertising, and legislative/lottery support given to address the problems of compulsive gambling.     

Transforming Social Work Curricula: Institutional Supports for Promoting Sustainability

Due to the centrality of human rights and social justice in the profession, social work must collectively take a stand on ecological degradation and the climate crisis. Overall, social work education's engagement with issues of sustainability and an expanded ecological justice perspective has been peripheral and piecemeal. It is crucial that social work education expand opportunities to prepare social workers to respond to the global environmental crisis. This conceptual paper considers strategies for integrating environmental content in social work curricula and addresses the essential role of institutional supports for curricular change and professional development focused on sustainability. The role of institutional supports to advance curricular change to respond to environmental crises and promote sustainability is highlighted, along with specific examples from the authors' home institution, including (1) institutional commitment and culture, (2) curricular supports and guidelines, and (3) interdisciplinary faculty development.     

Using a stress audit: The construction site manager experience in the UK

Abstract

The aim of this study was to conduct a stress audit among construction industry site managers in the UK as a precursor to a stress management intervention programme. Qualitative data were obtained from in-dept interviews with a total of 36 male middle and senior construction site managers; and aquantitative data were obtained by questionnaire. Based on the analysis of 561 postal quenstionnaires, eight stressor factors were identified, most significantly, ambiguity (i.e. role and task). Job satisfaction levels were low compared to a normative population and influenced by grade level. Measures of mental health were similar to the norm for males, but both grade of management and type of contract affected mental health. Anxiety levels were signficantly high, independent of managerial grade. The stress of work overload and role insecurity (fear of failure) were associated with reduced mental health and high anxiety, and the stress of the organizational culture and climate was the strongest predictor of job dissatisfaction. There was some cause for concern for the vulnerable high-risk groups, i.e. the extreme type A and those working overtime. Medical data from a small subset of managers (n = 78) revealed that this group evidenced a better quality of psychological health than the group in total; but a high percentage of personnel had high levels of triglycerides and cholesterol. Recommendations for action focused on the needs of specific subgroups, and guided the organization on the acceptability of possible interventions at individual, interpersonal and organizational levels.
