On nonlinear multi-covering problems

In this paper we define the exact k-coverage problem, and study it for the special cases of intervals and circular-arcs. Given a set system consisting of a ground set of n points with integer demands \(\{d_0,\dots ,d_{n-1}\}\) and integer rewards, subsets of points, and an integer k, select up to k subsets such that the sum of rewards of the covered points is maximized, where point i is covered if exactly \(d_i\) subsets containing it are selected. Here we study this problem and some related optimization problems. We prove that the exact k-coverage problem with unbounded demands is NP-hard even for intervals on the real line and unit rewards. Our NP-hardness proof uses instances where some of the natural parameters of the problem are unbounded (each of these parameters is linear in the number of points). We show that this property is essential, as if we restrict (at least) one of these parameters to be a constant, then the problem is polynomial time solvable. Our polynomial time algorithms are given for various generalizations of the problem (in the setting where one of the parameters is a constant).     

Personal reflection and experience of a Fulbright Scholar: teaching a mental health course in Vietnam’s changing culture

This paper documents the experience of developing and teaching a course on mental health for undergraduate social worker students during a semester in Vietnam. Social work is a profession at the early stages of development in Vietnam, requiring much curriculum development. There are over 40 universities with undergraduate social work education programs, but few of the faculty have had training or experience in practicing social work. The paper will summarize the main reasons for developing such a course given the current state of mental health need and services in a changing culture, as well as the current state of professional social work education and the newly established profession of social work. The author describes the contexts underlying the course—the status of social work and social work education in Vietnam, the context of mental health and mental illness in Vietnam, and curriculum adaptation to the cultural context. From this experience, the lessons learned about the role of cross-cultural critical thinking, cultural knowledge, and other strategies will be discussed about teaching a subject like mental health internationally.     

Using clinical signs of neglect to identify elder neglect cases

Elder neglect is the one of the most pervasive forms of mistreatment, and often the only place outside of the individual’s residence to identify and assist neglected individuals is in a medical setting. However, elder neglect cases treated in hospitals do not present with a single diagnosis or clinical sign, but rather involve a complex constellation of clinical signs. Currently, there is a lack of comprehensive guidelines on which clinical signs to use in screening tools for neglect among patients treated in hospitals. Using the DELPHI method, a group of experts developed and tested a scale to be used as a pre-screener that conceptually could be integrated into electronic health record systems so that it could identify potential neglect cases in an automated manner. By applying the scale as a pre-screener for neglect, the tool would reduce the pool of at-risk patients who would benefit from in-depth screening for elder neglect by 95%.     

Reactions of students to different settings of field experience

The study assessed Israeli students’ emotional–experiential reaction and attitude to different client populations, following a week-long experience in one of five social services settings. The study provides preliminary findings regarding the implications of first year students’ experience on their emphatic skills, a subject that generally has not received adequate scholarly attention. Using a purpose-built, self-administered questionnaire, we found students’ emotional–experiential response to their experience differed by the setting in which they were placed, being lowest in the Bedouin oriented services, intermediate among those placed in juvenile correction services, and highest in mental health, adult and child disability services. Responses were independent of all other explanatory variables, including sex, cognitive ability, previous training experience and perceptual shifts concerning the population served. We discuss possible reasons for these differences.

     

Fringe benefits and income inequality

In this paper, we analyze the distribution of fringe benefits among workers and underline its implications for income inequality. To this end, we develop a positional approach to inequality based on the concept of rent as a potential link between positions and their rewards. We hypothesize that workers extract rent in the form of benefits in industries with worker leverage (in the form of unioniziation, internal labor market, and public employment) or share rent with firms in highly profitable industries that endure for efficiency wage reasons. On the basis of a unique dataset from Israel, we test these hypotheses by estimating the probabilities of obtaining benefits according to industries’ structural features while controlling for cross-industrial differences in workers’ demographic and human capital characteristics. The analyses reveal that benefits are determined by structural factors, representing a separate dimension of the rewards attached to positions, different from earnings. We further stress the importance of incorporating fringe benefits into inequality research, given that benefits together with earnings stratify workers and evidently signify structured positions in the economy.     

What are Social Work Students’ Perceptions of the Community Practice Method?

Summary. A unique aspect of the social work profession is the combination of intervention on the personal, community, and societal levels and their interaction. The purpose of this research is to determine students’ perceptions of community practice. Qualitative research was conducted among Israeli social work students before gaining any practical experience in community practice. Findings. The results demonstrated a change in students’ perceptions of the importance of community practice to the profession, and the factors that contributed to this change. Applications. Recommendations that may contribute to changing students’ perceptions of community practice are offered to educators.     

The Role of Community in Disaster Response: Conceptual Models

We focus on the role that community plays in the continuum of disaster preparedness, response and recovery, and we explore where community fits in conceptual frameworks concerning disaster decision-making. We offer an overview of models developed in the literature as well as insights drawn from research related to Hurricane Katrina. Each model illustrates some aspect of the spectrum of disaster preparedness and recovery, beginning with risk perception and vulnerability assessments, and proceeding to notions of resiliency and capacity building. Concepts like social resilience are related to theories of “social capital,” which stress the importance of social networks, reciprocity, and interpersonal trust. These allow individuals and groups to accomplish greater things than they could by their isolated efforts. We trace two contrasting notions of community to Tocqueville. On the one hand, community is simply an aggregation of individual persons, that is, a population. As individuals, they have only limited capacity to act effectively or make decisions for themselves, and they are strongly subject to administrative decisions that authorities impose on them. On the other hand, community is an autonomous actor, with its own interests, preferences, resources, and capabilities. This definition of community has also been embraced by community-based participatory researchers and has been thought to offer an approach that is more active and advocacy oriented. We conclude with a discussion of the strengths and weaknesses of community in disaster response and in disaster research.     

Suzi and Mr. S.: Gender role stereotyping in social workers' court reports in custody and access cases.

This paper analyzes the “gender strategies” of a sample of Israeli women social workers as evidenced in the recommendations that they write for the courts on custody and visiting rights for divorcing couples. Textual analysis of these reports reveals what Hochchild terms a “traditional gender strategy,” manifested in a consistent pattern of gender stereotyping. There are clear differences in the way the social workers present the husband and wife as persons, both separately and in relation to one another, and in the roles that they expect them to fulfill, with the man being assigned the provider role and the woman the parent role. Even the way they collect information about the two parents' relationships with their children is different. The paper concludes with a discussion of the practical implications of the findings.

Abstract

There is a growing emphasis in the social work literature that social work's overall mission should be that of social justice and that mental health be relegated as outside of social work's realm. This paper draws upon a constructionist and narrative perspective in developing a general formulation of clinical social work to bridge the gap between social justice and mental health.
