This series of two articles presents a model of play development for use in pediatric occupational therapy. Proposing to unify the theoretical approaches of sensory integration and occupational behavior, the model uses play as the unifying link between these two apparently different approaches. This first article reviews the major concepts of sensory integration and occupational behavior, in ad...

This secondary analysis of qualitative interviews describes how older Swedish men approach the caregiver role for a wife with dementia, over time. An increasing number of male caregivers will become primary caregivers for partners living with dementia at home, and they will likely be caregivers for an extended period of time. It has been stated that caregiving experiences influence how older me...

BACKGROUND Conduction of thesis by the students is one of their major academic activities. Thesis quality and acquired experiences are highly dependent on the supervision. Our study is aimed at identifing the challenges in thesis supervision from both students and faculty members point of view. METHODS This study was conducted using individual in-depth interviews and Focus Group Discussions (...

A founder of the National Society for the Promotion of Occupational Therapy, Thomas Bessell Kidner (1866-1932) played a prominent role in the early development of occupational therapy in Canada and the United States. We describe Kidner's early life and how his work using occupations evolved. We then examine ideas and assumptions about occupations as treatment and trace Kidner's involvement thro...

There is currently considerable concern about the attractiveness of hospital medicine as a career and experiences in core medical training (CMT) are a key determinant of whether trainees continue in the medical specialties. Little is understood about the quality and impact of the current CMT programme and this survey was designed to assess this. Three key themes emerged. Firstly, the demands of...

Zonalow vacillation in an idealized two-layer, global, primitive-equation model is studied in the context of multiple regimes. The spatial structure of vertically and zonally averaged zonalow variability resembles that observed in the Southern Hemisphere, with dipolar anomalies centered at 40 and 60. The probability density function (PDF) of the model's zonal ow is studied in the subspace of it...

We characterize the practical receiver in a wide range of signal intensity for optical wireless communication, from discrete pulse regime to continuous waveform regime. We first propose a statistical non-linear model based on the photomultiplier tube (PMT) multi-stage amplification and Poisson channel, and then derive the optimal and tractable suboptimal duty cycle with peak-power and averagepo...

We present an experimental study of a new regime of monodisperse micro–droplet generation that we named the balloon regime. A dispersion of oil in water in a T–junction microfluidic system was studied. Several microfluidic devices having different cross– sections of the continuous and the dispersed phases micro–channels were tested. This new regime appears only for low dispersed phase velocity....

Slow changes in underlying state variables can lead to "tipping points," rapid transitions between alternative states ("regime shifts") in a wide range of complex systems. Tipping points and regime shifts routinely are documented retrospectively in long time series of observational data. Experimental induction of tipping points and regime shifts is rare, but could lead to new methods for detect...

hydraulics of stepped spillway is a very complicated phenomenon, as it consists of a two phase flow passing through a set of designed steps. the steps increase the rate of energy dissipation taking place on the spillway face. turbulence, flow aeration and energy dissipation are the main tasks in the design of such structures. this study consists of the experimental investigation to determine th...
