Development of a suitable measure of quality of movement, or gross motor performance, for children with cerebral palsy is a complex undertaking. A variety of conceptual, methodological, and practical issues inherent in such a project are discussed in this article. We report on the methodology used in the planning and construction of the Gross Motor Performance Measure. The measure has been deve...

THE design and use of laser photocoagulators for the treatment of pathological conditions in the eye has been described by Ingram, Manson, and Smart (1965) and Ingram (1966). When lesions need to be made close to the fovea, extremely precise positional control of the lesion is necessary. Involuntary eye movements (Boyce, 1967; Ditchburn and FoleyFisher, 1967) and human reaction times become imp...

We present a three-dimensional nonlinear finite element formulation for dielectric elastomers. The mechanical and electrical governing equations are solved monolithically using an implicit time integrator, where the governing finite element equations are given for both static and dynamic cases. By accounting for inertial terms in conjunction with the Arruda–Boyce rubber hyperelastic constitutiv...

The literature linking socioeconomic status and health has been accumulating for over a century (Antonovsky 1967). For much of this time, the focus has been on an individual’s social status or societal position as reflected either by their education, occupation, income or wealth acting as a fundamental determinant of health by influencing many different intermediate factors (Adler, Boyce et al....

Conductive silicone rubber has great advantages for tactile sensing applications. The electrical behavior of the elastomeric material is rate-dependent and exhibit hysteresis upon cyclic loading. Several constitutive models were developed for mechanical simulation of this material upon loading and unloading. One of the successful approaches to model the time-dependent behavior of elastomers is ...

There have been increasing numbers of media reports about careless behaviour by healthcare workers, mainly involving insufficient cleaning practices and the absence of hand hygiene measures (Boyce, 2009). Although adherence to infection prevention and control measures has received a lot of attention in the media and in scientific literature, surprisingly little attention has been given to the i...

We establish a principled schema design framework for data with missing values. The is based on the new notion of an embedded functional dependency, which independent interpretation values, able to express completeness and integrity requirements application data, capable capturing redundant value occurrences that may cause problems processing meets requirements. axiomatic, algorithmic, logical ...

Acknowledgements We are grateful to Maria Claudia Lopez and members of the Faculty of Environmental and Rural Studies at Javeriana University in Bogotá, Colombia who provided outstanding support for our work in the field. At each site, the experiments would not have been possible without the assistance of local community leaders that helped the research team develop credibility with local commu...
