A solution of the externality problem using strategic matching

This paper develops a Coase-like solution of the problem of inducing Pareto optimal behavior in the presence of reciprocal externalities. In place of Coasean direct compensation between the parties to an externality problem, actors strategically match each other's externality-producing activity, and thus induce counterparts to internalize the external benefits or costs of their actions. The analysis suggests a general framework for analyzing social interactions in the presence of reciprocal externalities. As an application of the theory, a solution of the duopoly problem is noted.We are indebted to L. Danziger, D.

You Have to Start from Scratch and You Need Someone by Your Side”: Perspectives of Parents and Teachers on Immigrant Students’ Adaptation to School

This article analyses the issue of immigrant students’ adaptation in Israeli schools, as perceived by their parents and teachers. The study integrates data from two qualitative, phenomenological studies: one explored immigrant parents’ perceptions of Israeli education and their children’s adaptation in school, while the other studied teachers’ perceptions of immigrant students’ education and their practices in the field. The data was gathered from in‐depth interviews with 17 parents and 20 teachers. The analysis yielded a list of themes related to parents’ and teachers’ views of the children’s adjustment, and their own roles in this process: their personal experiences in the field, the challenges and difficulties in interpersonal interactions between parents and teachers, and policy issues related to the educational integration of immigrant students. Findings emphasize the vital importance of parent‐teacher collaboration, clarification and better implementation of existing policy, and teachers’ qualifications for the successful educational integration of immigrant students.     

Coping Strategies and Relapse of Substance Abusers: A Case Study of the Therapeutic Community Program in Indonesia

The present study examined the ability of people with substance‐dependence problems to cope with stressful events and refrain from resuming alcohol drinking and the use of drugs. This study specifically examined the length of time that substance abusing‐residents spent in a state‐owned, residential‐based therapeutic community program at Lembang‐Bandung, West Java, Indonesia. A study sample of 68 residents completed a questionnaire with four sections. The results of this study showed no significant differences in the scores rating the coping behavior of the residents according to the length of stay in the program. This study also found no significant differences in the Coping Behavioral Inventory scores of the residents according to the level scores of total Coping Strategy Inventory. It is important for social workers to understand the relationship between the length of stay of residents and their ability to cope so that they can effectively engage in intervention work with individuals with substance‐dependence issues who participate in the therapeutic community.     

“Like My Status”

This paper engages with the relatively new area of research into teenage girls and online social networks, focusing on the experiences and views of Israelis. In particular, we examine how Israeli girls construct social relationships on Facebook. Adopting a feminist interpretive approach, this qualitative study is based on focus group interviews with Israeli girls aged between twelve and eighteen from diverse cultural, economic, and social backgrounds. The girls clearly distinguish between different circles of social closeness on Facebook, with each circle marked by different relationships, dynamics, and expectations. The study's findings beg the question of whether social networks allow Israeli girls to exercise control, power, choice, and agency in their social world, or whether they remain informed by existing social structures that shape and restrict their choices and actions. The significance of these findings is discussed in the contexts of feminism, girl power, and Neoliberal discourse.     

Ensuring units invariant slack selection in radial data envelopment analysis models,and incorporating slacks into an overall efficiency score

This paper introduces a new methodology ensuring units invariant slack selection in radial DEA models and incorporating the slacks into an overall efficiency score. The CCR and BCC models are units invariant in their radial component, but not in their slack component, thus changing the units of measurement of one or more variables can change the models' solution. The proposed Full Proportional Slack (FPS) methodology improves the slack selections of the CCR and BCC models by producing slack selections that (a) are units invariant, thus producing fully units invariant models, (b) maximize the relative improvements represented by the slacks, and not their values, and (c) measure the full slacks that need to be removed from their corresponding variables. The FPS methodology is a fully oriented methodology first maximizing the improvements in the variables on the side of the orientation of the model. The Proportional Slack Adjusted (PSA) methodology incorporates the FPS slacks into an overall efficiency score, making it easier to interpret and use the results. The FPS and PSA methodologies are illustrated using an input oriented VRS Loan Quality DEA model with data from the retail branch network of one of Canada's largest banks.     

Mechanisms of the Effect of Involuntary Retirement on Older Adults’ Self-Rated Health and Mental Health

This study examined mechanisms of the effect of involuntary retirement on self-rated health and mental health among adults aged 50 or older. Using two waves of the Health and Retirement Study (2006 and 2010), we selected a sample of 1,195 individuals working for pay at baseline who responded to a lifestyle questionnaire in both waves. Regression-based path analyses were conducted to test the mediating effects of financial control, positive and negative family relationships, and social integration on the relationship between involuntary retirement and self-rated health and mental health. Results of mediation analyses indicated that transition to involuntary retirement was directly negatively associated with subsequent self-rated health and indirectly negatively associated with mental health via perception of less financial control. Voluntary retirement was indirectly positively associated with both self-rated and mental health via perception of more financial control. No significant direct or indirect effects of retirement were found when retirement was measured with an aggregate measure without specifying its voluntariness. Findings emphasize the importance of specifying the voluntariness of retirement and recognizing the heterogeneity in the mechanisms of involuntary and voluntary retirement.     

Coalitions and Collaboration among Three Civil Society Immigrant Organisations in Israel

This article describes the creation of a coalition among three civil society immigrant organisations in Israel. The research questions dealt with the collaborative strategies adopted by these organisations, and investigated through ethnographic interviews and document analysis what factors facilitated inter-organisational collaboration. Results showed that these organisations provided complementary services to newcomers while struggling with hostile government policies. The collaboration dynamic between the groups was successful because these immigrant associations shared similar socialistic views. Furthermore, through the promotion of personal ties, inter-organisational solidarity was forged, but overall, these activities ran counter to the dominant Israeli culture.     

The Spatial Distribution of Quality of Life in the United States and Interstate Migration, 1965–1970 and 1985–1990

This study applies a relatively new method called ‘co-plot’ to examine the relationships between the 48 contiguous states of the United States and selected indicators of quality of life in 1970 and 1990, and how these characteristics coincide with five-year interstate migration rates. The findings show an overall process of polarization of quality of life throughout the country. Strong similarity was found between states of a given division or region. The states which composed New England, the Middle Atlantic and the Pacific divisions are located in the strong sector of the socio-economic space. The direction of migration is toward states of the more external belts of the country. In the second part, multiple regression analysis was applied revealing a strong effect of economic incentives on migration; over time; migration turns into a widespread phenomenon among different socio-economic groups, with income becoming less significant as a predictor of interstate migration.     

Family Characteristics and Traumatic Consequences Associated with the Duration and Frequency of Sexual Assault

The objective of this study was to analyse the relationship between family characteristics and the trauma associated with the duration and frequency of sexual assault on child survivors in the state of Sabah, Malaysia. Eighty children who reported sexual assault through a one stop crisis centre in an urban hospital were studied. The main research instrument used was adapted from the trauma symptoms checklist for children. The results of the study show that there are significant differences between the symptoms of trauma of victims according to the frequency of sexual assault, but not according to its duration. Social workers need both to understand and to take note of the relationship of the variables of family characteristics, frequency of sexual assault and trauma effects on the victims in their intervention work with child sexual assault survivors who report having been abused. The implications of these findings are discussed in the context of providing crisis intervention by social workers in Malaysia for child victims of sexual assault.
