OBJECTIVE The purpose of this study was to develop a program evaluation tool through a client-centered approach. Client satisfaction questionnaires previously developed for service recipients of a pediatric seating clinic have reflected the professionals' views on what should be asked. METHOD Seven parents and caregivers of recent service recipients of the seating clinic participated in tape-...

OBJECTIVE Because of risks from deploying airbags to children in front seats, extensive publicity has been aimed at getting them restrained and in rear seats. The objective of this study was to assess restraint use and seating positions among children in vehicles with and without airbags. METHOD Surveys were conducted in cities in Michigan, North Carolina, and Texas 1998. Restraint use and se...

A rigorous description of the magnitude and direction of the 3D force vector each thumb muscle produces at the thumb-tip is necessary to understand the biomechanical consequences to pinch of a variety of paralyses and surgical procedures (such as tendon transfers). In this study, we characterized the 3D force vector each muscle produces at the thumb-tip, and investigated if these thumb-tip forc...

In this paper, we exhibit a combinatorial model based on seating rearrangements, motivated by some problems proposed in the 1990’s by Kennedy, Cooper, and Honsberger. We provide a simpler interpretation of their results on rectangular grids, and then generalize the model to arbitrary graphs. This generalization allows us to pose a variety of well–motivated counting problems on other frequently ...

This study investigated the relationship between classroom seating arrangements and the question-asking of fourth-graders. Data were collected during 53 lessons spread over 8 weeks. Children were assigned to sit in a semicircle and then in a row-and-column seating arrangement for 2 weeks each. This rotation was repeated. Both children’s questions and the teacher’s verbal reactions were recorded...
