‘Growing Old’ in Shelters and ‘On the Street’: Experiences of Older Homeless People

Homelessness among older people in Canada is both a growing concern, and an emerging field of study. This article reports thematic results of qualitative interviews with 40 people aged 46 to 75, carried out as part of a mixed-methods study of older people who are homeless in Montreal, Quebec, Canada. Our participants included people with histories of homelessness (n = 14) and persons new to homelessness in later life (n = 26). Interviews focused on experiences at the intersections of aging and homelessness including social relationships, the challenges of living on the streets and in shelters in later life, and the future. This article outlines the 5 main themes that capture the experience of homelessness for our participants: age exacerbates worries; exclusion and isolation; managing significant challenges; shifting needs and realities; and resilience, strength, and hope. Together, these findings underscore the need for specific programs geared to the unique needs of older people who are homeless.     

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.     

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.     

Quality of Life in South Africa: Post-Apartheid Trends

During the apartheid era black South Africans indicated markedly lower levels of happiness and satisfaction in all spheres of life than their white counterparts. The gap between black and white subjective well-being closed temporarily after the first universal franchise elections held on April 27, 1994 only to widen again eighteen months later. The paper presents data on subjective well-being collected during the 1980s and 1990s in four nationwide cross-sectional attitude surveys and a multipurpose household survey. Possible explanations for the shifting levels of happiness are explored. These include levels of living, income inequality, rising expectations and new anxieties experienced in the post-apartheid era.     

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.
