Games with capacity manipulation: incentives and Nash equilibria

Studying the interactions between preference and capacity manipulation in matching markets, we prove that acyclicity is a necessary and sufficient condition that guarantees the stability of a Nash equilibrium and the strategy-proofness of truthful capacity revelation under the hospital-optimal and intern-optimal stable rules. We then introduce generalized games of manipulation in which hospitals move first and state their capacities, and interns are subsequently assigned to hospitals using a sequential mechanism. In this setting, we first consider stable revelation mechanisms and introduce conditions guaranteeing the stability of the outcome. Next, we prove that every stable non-revelation mechanism leads to unstable allocations, unless restrictions on the preferences of the agents are introduced.     

El modelo de reactancia-indefensión de Wortman y Brehm desde la perspectiva de la psicofisiología social

Resumen

Este estudio fue diseñado para poner a prueba la hipótesis de reactancia-indefensión de Wortman y Brehm (según la cual los efectos producidos por la incontrolabilidad están mediados por la duración del evento incontrolable) en relación al funcionamiento corporal. Para ello, se eligió como principal variable dependiente el control de la respuesta electromiográfica de la musculatura frontal. Se utilizó un diseño factorial 3 (expectativa de control alta, baja y nula) X 2 (entrenamiento en incontrolabilidad corto y largo). Asimismo, se incluyeron medidas sobre «locus de control», estilo atribucional, percepción y estrategias de control. Los resultados obtenidos confirman parcialmente la hipótesis establecida y son discutidos dentro del ámbito de la Psicofisiologia Social.     

Negotiating Conflict through Music: The Case of the Tsonga Tingoma Ritual

Abstract

Tingoma is a three-day ritual conducted by Tsonga people to facilitate communication between the living and their Ancestor spirits, and to ensure that there is no disharmony between the beings in these two realms. Using a tingoma conducted for Eunice Maluleke as a case study, we argue that this ritual not only negotiates tension within an individual (body and spirit), and between an individual and his or her Ancestor spirits, but also functions as a site through which larger social and political tensions are addressed. Further, we propose that the structure of tingoma as it is practiced today inscribes and negotiates inter-ethnic tensions of the past. In the second part of this article we examine the ways in which tingoma has been affected by, and engages with, more recent power struggles and related identity politics, specifically those relating to the religious and political affiliations of people residing in South Africa's Limpopo province since the early 1980s.     

Elders' Decisions To Enter Assisted Living Facilities: A Grounded Theory Study

ABSTRACT

The purpose of this qualitative study was to develop a substantive theory of elders' decision-making process to relocate to an assisted living facility. The researchers interviewed a purposive sample of 28 elders who resided in assisted living facilities. The theory of elders' decisions to relocate to an assisted living facility is a story about elders weighing and balancing gains and losses to go to where the help is. Decision makers weigh and balance gains and losses before, during, and after relocating to an assisted living facility. Elders stay at their current residence if gains outweigh losses and they relocate if losses outweigh gains. Understanding the process of decision-making in this segment of the population may lead to the development of interventions that can promote positive relocation experiences among elders and increase the effectiveness of their decision-making behaviors.     

Youth with Serious Mental Health Disorders: Wraparound as a Promising Intervention in New Zealand

Youth with serious mental health disorders present with a complexity of challenges for the mental health system, schools, youth justice, care and protection, and their communities. Research shows their needs are best achieved by providing coordinated intensive, multidisciplinary, and individualised services. This article outlines the prevalence and characteristics of youth with serious mental health disorders. It also discusses community‐based interventions used in New Zealand and their limitations. It introduces Wraparound, an intensive individualised coordination and care planning process as a promising practice for youth with serious mental health disorders and their families. Key principles and phases underpinning the Wraparound process are presented along with a case vignette to exemplify the process. Its theory of change, the challenges experienced in practice, and a brief overview of the evidence‐base are also discussed.     

Family,welfare state generosity and the vulnerability of older adults: A cross-national study

The availability of family can be considered a protective factor for aging well. In this article, we examine to what extent the family situation of older people creates vulnerability with respect to their quality of life. Because not everyone is vulnerable to the same degree, we try to identify the conditions under which older people benefit more from having family resources. Based on the resources perspective, we argue that the impact of family resources on life satisfaction is stronger for older people with fewer resources at both the individual level (material, physical and non-familial social resources) and the country level (welfare state services targeted at older adults). To test our hypotheses we make use of the fourth wave of the European Values Study, and the MULTILINKS Social Policy Indicators database. In general our data offer support for the idea that the presence of intimate family ties (with partner and children) can be considered an important resource for achieving psychological well-being, whereas their absence or loss may act as a constraint. Our vulnerability argument is partly supported by the findings. Partner resources are more important for the life satisfaction of older people with a low education and health problems. Similarly, having children only improves the life-satisfaction of lower educated older adults. However, family resources are not more important for older people with fewer material resources or for older people living in countries with low services levels targeted at older adults.     

How do men with paraplegia choose activities in the light of striving for optimal participation? A qualitative study,based on a phenomenological–hermeneutical method

The objective of this study was to explore the experiences of men with paraplegia with regard to how they choose activities. The study involved a qualitative research design, based on a phenomenological–hermeneutical method. The findings revealed that the activities participants were choosing could be on a continuum between the individual’s self and the influence from their environment. On this continuum, the choice to perform activities was influenced by two mediating factors: the individual’s activities performed during their life-history, and their activity challenges for the future. We conclude that choosing activities is an individually constructed internal process of negotiation. Feelings of resignation and revolt appear in combination with feelings of justice and injustice when balance is not found. This knowledge provides a better understanding of the impact of spinal cord injury, sheds light on the development of distress after spinal cord injury and sheds new light on individuals’ feelings of participation.     

Young Dutch People's Experiences of Trading Sex: A Qualitative Study

In recent years, the subject of transactional sex among young Dutch people has generated a heated social debate in the Netherlands. However, accurate data on this phenomenon are scarce. This article describes the findings of a qualitative study on young Dutch people's experiences of having sex in return for money or a material reward. Thirty in-depth interviews were conducted with young Dutch men and women aged 14 to 24. Participants came from diverse backgrounds in terms of gender, ethnicity, sexual orientation, and socioeconomic status. Experiences of trading sex differed in terms of the motivation to trade sex, the presence or absence of coercion, and the availability of other options for earning money. Participants' feelings about their experiences varied. For most participants, the sex itself was unpleasant and required considerable emotion management. Still, some felt adequately compensated by the reward or felt trading sex was preferable to other jobs. Gender played an important role, with feelings of disgust or shame reported especially by female participants, whereas male participants reported more positive experiences. Interactions involving coercion or financial dependence on trading sex generally had a negative emotional impact. Participants stressed the differences between their own experiences and professional prostitution.
