The minimal overlap rule revisited

This paper provides an analysis of the Minimal Overlap Rule, a solution for bankruptcy problems introduced by O’Neill (1982). We point out that this rule can be understood as a composition of Ibn Ezra’s proposal and the recommendation given by the Constrained Equal Loss Rule. Following an interpretation of bankruptcy problems in terms of TU games, we show that the Minimal Overlap Value is the unique solution for bankruptcy games which satisfies Anonymity and Core Transition Responsiveness.     

Expanded renal transplantation: a competing risk model approach

Multi-state models (MSMs) are useful to analyze survival data when, besides the event of main interest, one or more intermediate states of the individual are identified. These models take the several existing states and the possible transitions among them into account. At the same time, covariate effects on each transition intensity may be investigated separately and, therefore, MSMs are more flexible than the standard Cox proportional hazards model. In this work, we use MSMs to investigate the impact of the quality of a transplanted kidney for a group of patients at the Hospital Universitario Central de Asturias. Specifically, we use an illness-death model to study the evolution of patients with kidney disease who received a renal transplant after a dialysis period. The intermediate state is defined as the failure of the received organ, while the terminating state is the death of the patient. In order to increase the potential number of organs available for transplant, the standards of quality for the transplanted kidneys were relaxed (the new criteria are labeled expanded criteria), and these ‘expanded kidneys’ were transplanted in appropriate candidates (older patients, with higher prevalence of diabetes mellitus). Results suggest that the expanded kidneys have a minor effect on survival, while both the kidney mortality and the risk of death increase with the patient's age and the serum creatinine and serum hemoglobin levels.

Where Does it Begin? A Comparative Perspective on the Professional Preferences of First-year Social Work Students

Correspondence to Dr John Gal, Paul Baerwald School of Social Work, The Hebrew University, Mt Scopus, Jerusalem 91905, Israel. Summary The goal of this paper is to contribute to a better understandingof international social work by examining the professional preferencesof students at the beginning of the social work training processin the United States, Great Britain and Israel. The study, uponwhich the paper is based, examined the preferences of the studentswith regard client groups, social services, types of sectorsand of practices, and sought to identify the similarities andthe differences between these preferences in different countries.The findings indicate that the students from the United Statesand Israeli universities prefer to work with social groups andto be employed in services, that can be defined as "less stigmatic",while these trends were not identifiable in the case of theBritish students. They expressed a greater readiness to workwith more needy social groups and to find employment in thestate sector. By contrast, the students in all the universitiesstudied expressed a similar unwillingness to work the unemployed,the chronically ill and to find employment in old-aged homes.In addition, casework with individuals was the most preferredtype of social work practice. Clearly, the findings indicatethat the preferences of students in different countries reflectvariations in the nature of social work in each of the specificnational settings.     

Temporary Skilled Migration to Australia: Employers' Perspectives1

With the 1996 introduction of a new visa making it easier for employers to sponsor skilled foreign workers, temporary skilled migration has become a significant component of international migration flows to Australia. This paper examines employers' reasons for sponsoring skilled workers from abroad, their modes of recruitment, the occupational skills they require, and their industry profile. We also discuss issues relating to the perception of a shortage of skilled workers, the extent that sponsoring foreign workers substitutes for investing in local training, and the role of networks in recruiting overseas workers. Many employers' now have a global view of labour recruitment. While this is understandable for multinational companies with global operations, many small businesses and public sector institutions are adopting the same strategy to obtain skilled labour which they say is in short supply in Australia. With the internationalization of the Australian economy, there is also an increasing demand for people with specialized skills and knowledge that is not available in Australia's relatively small labour market. An understanding of the demand factors motivating temporary skilled migration is crucial to effectively managing Australia's migration and labour trends.     

Does Iconicity in Pictographs Matter? The Influence of Iconicity and Numeracy on Information Processing,Decision Making,and Liking in an Eye‐Tracking Study

Researchers recommend the use of pictographs in medical risk communication to improve people's risk comprehension and decision making. However, it is not yet clear whether the iconicity used in pictographs to convey risk information influences individuals’ information processing and comprehension. In an eye‐tracking experiment with participants from the general population (N = 188), we examined whether specific types of pictograph icons influence the processing strategy viewers use to extract numerical information. In addition, we examined the effect of iconicity and numeracy on probability estimation, recall, and icon liking. This experiment used a 2 (iconicity: blocks vs. restroom icons) × 2 (scenario: medical vs. nonmedical) between‐subject design. Numeracy had a significant effect on information processing strategy, but we found no effect of iconicity or scenario. Results indicated that both icon types enabled high and low numerates to use their default way of processing and extracting the gist of the message from the pictorial risk communication format: high numerates counted icons, whereas low numerates used large‐area processing. There was no effect of iconicity in the probability estimation. However, people who saw restroom icons had a higher probability of correctly recalling the exact risk level. Iconicity had no effect on icon liking. Although the effects are small, our findings suggest that person‐like restroom icons in pictographs seem to have some advantages for risk communication. Specifically, in nonpersonalized prevention brochures, person‐like restroom icons may maintain reader motivation for processing the risk information.     

Social Support Interventions in Migrant Populations

The phenomenon of immigration has led to an important increasein the number of social programmes and services for migrantpopulations in many European countries. However, some investigationshave shown that the use of formal resources is extremely lowin these groups. In contrast to the limited utilization of programmesand services, research in the field of social psychology hasrevealed that the primary source of help and support for immigrantsis their own informal social network. After analysing the characteristics,advantages and limitations of formal and informal support systems,this paper presents a typology of social support interventionswith migrant populations that integrates both types of support.Four levels are differentiated: dyadic interventions, socialnetwork interventions, mutual aid groups and community interventions.The development of programmes to strengthen the informal supportsystem is emphasized as an alternative to integrating formaland informal resources in social work practice with migrantpopulations.
