Modeling human-bed interaction: the predictive value of anthropometric models in choosing the correct bed support

The sleep system (i.e. the combination of mattress and bed base) is an important factor of the sleep environment since it allows physical recuperation during sleep by providing proper body support. However, various factors influence the interaction between the human body and the sleep system. Contributing factors include body dimensions, distribution of body weight and stiffness of the sleep system across the mattress surface. During the past decade, the rise of several new bedding technologies has made it increasingly difficult for the consumer to select a proper sleep system. Therefore, this study presents a method to model human-bed interaction in order to objectively predict the ideal sleep system for a particular individual. The proposed method combines a personalized anthropometric model with standardized load-deflection characteristics of mattress and bed base. Results for lateral sleep positions show a root mean square deviation of 11.9 ± 6.1 mm between modeled spine shapes and validation shapes, derived from 3D surface scans of the back surface. The method showed to be a reliable tool to individually identify the sleep system providing superior support from a variety of possible mattress-bed base combinations.     

Managing the flow of private information on children and parents in poverty situations: Creating a panoptic eye in interorganizational networks?

In this article, we discuss how the flow of private information about children and families in poverty situations is managed in interorganizational networks that aim to combat child poverty. Although practices for sharing information and documentation between child and family social work services are highly encouraged and recommended to create supportive features for parents and children, this development often results in undesirable forms of governmentality. Interorganizational networking also creates controlling side effects because the exchange of information in networks of child and family services may wield a holistic power over families. We theorize this issue by using the Foucauldian concepts of the panopticon and pastoral power, which allows us to grapple with the major tension between support and control in the information‐ and documentation‐sharing practices of social workers. A critical analysis of our empirical data reveals four central fields of tension in which social workers and their organizations must position themselves: (a) craving control and handling uncertainty, (b) using and misusing private information and trust, (c) constructing families as subjects and objects of intervention, and (d) including and excluding families.     

Retirement timing in Europe: The influence of individual work and life factors

This study considers the rational choice and life course theories to predict European retirement timing. It is relevant to compare men's and women's retirement decisions to determine whether they are influenced by work or by the interplay between work and familial, educational, and leisure life. An event history analysis of the European Community Household Panel (ECHP) suggests that work factors have a greater impact on European women's retirement timing than they do for men and that both men's and women's retirement timing is influenced by the interplay of work and life.
