A robust prediction error criterion for pareto modelling of upper tails

Estimation of the Pareto tail index from extreme order statistics is an important problem in many settings. The upper tail of the distribution, where data are sparse, is typically fitted with a model, such as the Pareto model, from which quantities such as probabilities associated with extreme events are deduced. The success of this procedure relies heavily not only on the choice of the estimator for the Pareto tail index but also on the procedure used to determine the number k of extreme order statistics that are used for the estimation. The authors develop a robust prediction error criterion for choosing k and estimating the Pareto index. A Monte Carlo study shows the good performance of the new estimator and the analysis of real data sets illustrates that a robust procedure for selection, and not just for estimation, is needed.     

A robust test for asymptotic independence of bivariate extremes

We show that the existing tests for asymptotic independence are sensitive to outliers. A robust test is proposed. The new test is made stable under contamination through a shrinkage scheme. Simulations show that the new test performs well in the presence of contaminated data while maintaining good properties when there is no contamination. An application to real data shows the added value of our new robust approach.     

The Use of Common Humanity Scenarios to Promote Compassion in Healthcare Workers

ABSTRACT

The importance of compassion in healthcare is universally acknowledged. However, the factors that enhance compassion are not well understood. The perception of common humanity has been proposed as a prosocial perspective that leads to unbiased universal compassion. There has been a lack of research into the relationship between common humanity and compassion. This study examined the use of common humanity scenarios to promote compassion in healthcare workers. Seventy-five healthcare workers were randomly assigned to two groups and shown a different common humanity scenario. The healthcare workers were asked what effect viewing the videos had on their perception of common humanity and compassion. Thematic analysis was used to identify themes. Four main themes emerged: (a) common bonds; (b) people have the same needs; (c) no one wants to suffer; (d) seeing strangers helping others is motivating. Healthcare workers reported feelings of care, concern, and compassion after viewing common humanity scenarios.

IMPLICATIONS

• Viewing common humanity scenarios appears to lead to enhanced feelings of connection to others and compassion in healthcare workers.

• Using common humanity scenarios may be a useful compassion training strategy in healthcare.

• Further research is necessary to gain a better understanding of how viewing common humanity material influences compassion.

     

Psychosocial Well-Being of the Elderly and Their Perception of Matured Estate in Singapore

This article explores various relationships between the elderly's psychosocial well-being and components of aging-friendly community (continuity, compensation, connection, challenge, and contribution), in order to understand their perception of a matured estate and to discuss implications in housing neighborhood urban design. Interviews with elderly residents living in Bukit Merah (Redhill), one of the matured housing estates in Singapore with a high percentage of elderly residents, were conducted to understand how eldercare infrastructure and social spaces developed within the fabric of a high-rise, high-density public housing estate can support or inhibit their psychosocial well-being, as indicated by the Geriatric Depression Scale (GDS). Our results postulate that different groups of elderly form friendships and participate in activities in both formal social service centers and informal public spaces. The friendships formed in these places and the convenience of amenities around their houses may affect their perception of their current residences. While the elderly residents are generally satisfied with physical infrastructure, a comprehensive, integrated urban design is further needed to facilitate physical activities, social interactions, and active aging in the elderly in order to enhance their psychosocial well-being.     

Experiencing menopause in the UK: The interrelated narratives of normality,distress, and transformation

ABSTRACT

We investigated the experience and perspectives of menopause among 48 UK mothers through qualitative in-depth interviews. Interviews were analyzed thematically then explored using social science theories. Three interdependent narratives emerged: menopause as a normal, biological process, distinct from self and social transitions; menopause as struggle, an “idiom of distress” expressing upset, identity loss, shame, and social upheaval; and menopause as transformative and liberating, arising from biopsychic and relational changes. Some women followed a predictable “rite of passage” trajectory with transformation emerging from distress, but not all: Menopause arises from a complex interplay of personal predicament, somatic change, and sociocultural context.     

A Critical Evaluation of the Contradictions for Disabled Workers Arising from the Emergence of the Flexible Labour Market in Britain

In Britain, as in all industrialised countries 'paid work' or employment is central to the economy of the state. This perspective raises important implications for theories of disability and work, and for further research in this area. This paper attempts to provide a critical evaluation of the contradictions arising from the flexible labour market for disabled workers and how the concept of the Disabled State has been eroded along with notions of disabled people as the 'deserving poor'. Policies now demonstrate a commitment to a labour market free from restrictive practices and regulation. It appears that new technologies and specific personal communication skills, initiative, flexibility and adaptability will play an increasing part in new labour working trends. In short, theories of disability and work must change focus from 'production' to 'process'.     

Mapping social work education in the West Africa region: Movements toward indigenization in 12 countries’ training programs

This article presents the results of a systematic mapping of social work training programs in countries throughout West Africa, a region historically under‐represented in global discussions of the social welfare workforce. The research illuminates how social workers and related professionals are trained to engage in social work practice in a number of West African countries. The research was conducted in two phases. In the initial phase, the research team collected documents from 12 West African countries and conducted phone interviews with relevant individuals. The second phase included field research in five West African countries ? Burkina Faso, Côte d’Ivoire, Ghana, Nigeria, and Senegal ? where the research team conducted semi‐structured interviews and group discussions with 253 individuals. Framed by indigenization theory, this study describes social service training institutes in West Africa and highlights the varying degrees to which programs have been adapted to indigenous and endogenous realities in the postcolonial era.
