Operations research in the management of the airlines

This paper is intended to present an introduction to the use of operations research in the international airline industry, and to demonstrate the scope and significance of the airline OR activities. First, the special reasons for the viability and spread of airline OR are discussed. Then a functional framework for an airline is outlined, to be used in analyzing the problems of an airline and relating the OR work to it. Four major applications are described, corresponding to four major components of the framework. These applications are: schedule development, overbooking control, crew scheduling and engine management, respectively. In each case we describe the problem and its significance, indicate the types of solution techniques which have been developed, and assess the implemented solutions. The paper concludes with comments on the current state-of-the-art and the future of airline OR. A detailed bibliography is given.Both of the authors have been operations research directors in major airlines and more recently have focused their attention upon the industry as academic researchers. This background has provided us with an unusual opportunity to analyze the role of OR in the airlines, and our paper seeks to share with the reader some of the insights we have gained thereby.     

Divorce is a part of my life… Resilience, Survival, and Vulnerability: Young Adults' Perception of the Implications of Parental Divorce

A qualitative study among 22 young adults (20–25 years old) whose parents divorced during their childhood was conducted in Israel, using semi-structured, in-depth, open-ended interviews. Qualitative data analysis led to identification of three profiles, aiming at a grounded theoretical conceptualization. Three core themes were identified: the centrality of the family; short- and long-term implications of parental divorce and its relations to supportive coping resources; and perspective at young adulthood. Further analysis led to typifying participants by three profiles, which represent the grounded theoretical conceptualizations: resilience, survival, and vulnerability. The most prominent difference among the profiles was the relationships between participants and their parents, and their perception of ongoing parental responsibility. A thorough discussion of the results and their implications for future research, theory development, and practice are presented.     

Money Matters: Young Adults’ Perception of the Economic Consequences of their Parents’ Divorce

A qualitative study examined the perceptions of 22 Israeli young adults (ages 20–25) of childhood parental divorce. Respondents discussed their experiences, including economic consequences of the divorce. Results related to the practical aspect of economic decline, to economic issues as embodiment of parental conflicts, and to children’s emotional and practical roles connected to economic changes. Children’s understanding and coping with financial issues are related to three profiles of overall adjustment identified in this study—resilience, survival, and vulnerability. Resilient young adults interpreted as empowering their understanding and coping; the survivors recognized their efforts as meaningful but burdensome; and vulnerable participants felt that economic changes caused a heavy financial and emotional price. Limitations and implications are discussed.

股东参与治理的私人收益和社会收益的实证研究

本文探讨了股东参与治理所带来的私人收益、特定股权结构的社会收益以及股权集中成本三者之间的关系。我们分析的结果表明,当股东与经理人员之间的利益冲突水平较高、其它治理机制的作用较弱时,股权集中(股东参与治理的积极性较高)可以创造大量的社会收益;反之,股权的集中与分散程度(股东参与治理的积极性较低)对社会收益的影响不明显。本文的研究结论为我国股东参与治理及股权结构改革提供了重要启示。     

Issues in intervention with battered women in collectivist societies

Over the past three decades, several models for individual and group intervention with battered women have been developed. The common assumption underlying all of these models is that violence and abuse are never appropriate in an intimate relationship, and that battered women have a basic right to safety, which is not negotiable. Because almost all of those models were developed in the individualistic contexts of Western societies, some questions and concerns have been raised as to their suitability for intervention with battered women in collectivist contexts. In this article, we explore the characteristics of collectivist societies based on the conceptual framework of Triandis, Brislin, and Hui, (1988) which focuses on five dimensions: the self, attitudes, values, activities, and behaviors. Furthermore, we explore each of those dimensions and their relevance to various aspects of wife abuse in collectivist societies, such as the way that battered women cope with violence against them, and possibilities for professional intervention.     

Division of Labor and Decision-Making in Arab Families in Israel: Processes of Change and Preservation

The study examines the changes that Arab families in Israel have undergone over three generations. It focuses on change and preservation in the division of labor between spouses, in the attitudes toward it, and оn how decisions are made in the family. It also examines the factors contributing to the preservation of traditional characteristics and those contributing to change. The study included 378 Moslem and Christian Arab women from three generations (grandmothers, mothers, and daughters). The findings indicate significant changes: the younger the generation is, the less traditional are the attitudes it holds and the more egalitarian the life of the couple is. The factors found to promote change were the woman’s education, work outside the home, intensive contacts with the Jewish population, and living near Jewish communities. The factor that was found to contribute most to the preservation of traditional patterns is consensual solidarity with the mother.     

Perception of job satisfaction, service effectiveness and burnout among Arab social workers in Israel

Over the past three decades, the topics of job satisfaction and burnout have become a major focus of interest in research and professional training in the field of social work. However, there is a serious lack of studies focusing on these issues in the context of Arab social workers in Israel. This paper presents the results obtained from a subsample of Arab participants in a national study of Israeli social workers. It focuses on the correlations between several career outcomes and organizational conditions such as role characteristics, work conditions, job mastery, and power. Challenge at work and job mastery were found to be the most significant and consistent predictors of the outcome results. The implications of the results are also discussed.     

The potential role of social and familial networks in shaping the well-being of children in shelters for women survivors of intimate partner violence

Children living in households where severe intimate partner violence (IPV) exists sometimes move with their mothers to shelters for battered women. Although there is an increased interest in research exploring children's exposure to IPV, little is known about children's subjective experiences during their stay in shelters. The present study examines children's views of their disconnection from their social and familial networks during their stay in a shelter. Using qualitative methods, 32 children, ages 7–12 years, who resided in a shelter were interviewed. Thematic analysis was implemented to develop codes and themes. The following five themes emerged from the data analysis: (a) absence of grandparents, (b) worry about older siblings, (c) disconnection from the neighbourhood, (d) missing their house and (e) disconnection from previous school and classmates. Findings suggest that children's disconnection from previous formal and informal networks significantly affected their well-being. The findings are discussed and interpreted in light of selected key concepts of Bronfenbrenner's bioecological model. The limitations of this study are discussed, along with implications for future research, as well as highlights for future intervention.
