On the graphical display of the significant components in two-way contingency tables

Graphical methods have been previously proposed for studying the cell contributions to the chi-square statistics in two-way contingency tables. Clustering techniques are suggested for analyzing the differences among the frequency distributions of either the columns or the rows of the contingency cables. Modifications are proposed to the other methods: first, varying widths of bars according to the expected cell counts, then the gannria probability plot of the individual chi-square terms.     

A pseudo-complete sample technique for estimation from censored samples

An iterative procedure is presented whereby singly right censored samples are transformed into pseudo-complete samples. This involves the use of order statistics to calculate expected “complete” values of the censored observations. Estimates of the distribution parameters are then calculated by employing standard complete sample estimators. This procedure is applicable to various types of distributions.     

Optimizing Customer Forecasts for Forecast‐Commitment Contracts

We study a “Forecast‐Commitment” contract motivated by a manufacturer's desire to provide good service in the form of delivery commitments in exchange for reasonable forecasts and a purchase commitment from the customer. The customer provides a forecast for a future order and a guarantee to purchase a portion of it. In return, the supplier commits to satisfy some or all of the forecast. The supplier pays penalties for shortfalls of the commitment quantity from the forecast, and for shortfalls of the delivered quantity from the customer's final order (not exceeding the commitment quantity). These penalties allow differential service among customers. In Durango‐Cohen and Yano (2006), we analyzed the supplier's problem for a given customer forecast. In this paper, we analyze the customer's problem under symmetric information, both when the customer is honest and when he strategically orders more than his demand when doing so is advantageous. We show that the customer gains little from lying, so the supplier can use his control over the contract parameters to encourage honesty. When the customer is honest, the contract achieves (near‐)coordination of the supply chain in a great majority of instances, and thus provides both excellent performance and flexibility in structuring contracts.     

Adjustment to disability

This article will focus on the biopsychosocial challenges encountered when an individual is disabled at an early age as well as when an individual acquires a disability later in life. Two case examples will focus on the adaptations/life choices that are necessary to adequately meet psycho/social/developmental needs and enhance individual self esteem. The case of Rita, a woman who lost her hearing at age two, highlights the importance of integrating a biopsychosocial approach to understand the multiple challenges and adaptations of individuals who are disabled at an early age. Laureen, a woman who acquired a spinal cord injury during her late teen years, described her struggles as a young adult adapting to a physical disability. Both cases highlight the importance of integrating an ecological/systems framework focusing on a biopsychosocial perspective, emphasizing the interrelationship between biological, psychological, social, technological, cultural and political factors.     

Closer to home: parent mentors in child welfare

This article addresses the emerging use of parent mentors--parents who have successfully negotiated the child welfare system and provide support and advocacy to others. The theoretical justification, roles, and expected outcomes and benefits of parent mentors are explored. The organizational factors thought to be required for such programs are also described, drawing on the available literature and the practice experience of a recently implemented Parent Partners program in a county child welfare agency.     

Intergenerational service-learning: an innovative teaching strategy to infuse gerontology content into foundation courses

This article provides an overview of intergenerational service- learning, an experiential pedagogy that involves students in learning outside the traditional classroom while providing a needed service in the community. Examples of intergenerational service-learning projects are presented that have been successfully utilized by the authors. These projects demonstrate the importance of using reflective practice assignments to help students deconstruct and reconstruct images, beliefs and paradigms about older adults. In addition, problems and opportunities in developing service-learning projects in urban and rural settings and with the Hispanic community are described, as well as some of the types of learning that may result from implementing service-learning experiences in various social work foundation courses.     

The reflection of desire for revenge and revenge fantasies in drawings and narratives of sexually abused children

Whereas the desire for revenge for an unjust deed is considered natural, its use within the therapeutic setting is scarce, specifically in sexually victimized children. The study aimed to find how experiencing sexual molestation during childhood and the revenge fantasy is reflected in drawings and narratives of sexually victimized children. Following ethical approval and signing a consent form, 14 children who experienced sexual abuse and were psychologically treated (ages 11–18) were recruited. They were asked to draw two drawings: “draw an unjust event that had happened to you” and “draw what you would have liked to happen to the person that unjustly treated you.” At completion, participants were asked to give a narrative to each drawing. Phenomenological analysis of the drawings and narratives indicated that most participants refrained from using more than two colours, did not draw the perpetrator and drew schematic figures. The main themes that emerged in the drawings and the narratives were feeling of loneliness, aloneness, and the desire for role reversal.
