This paper presents a novel shooting method for solving two-point boundary value problems for second order ordinary differential equations. The method works as follows: first, a guess for the initial condition is made and an integration of the differential equation is performed to obtain an initial value problem solution; then, the end value of the solution is used in a simple iteration formula...

BACKGROUND As a result of managed care mandates for primary care and the growing community presence of the 6 million mentally handicapped persons in the United States, primary care of this population will increasingly be provided by family physicians. How much family practice residencies emphasize training for care of this population is the focus of this study. METHODS A questionnaire was mai...

Life history theory predicts that parents will balance benefits from investment in current offspring against benefits from future reproductive investments. Long-lived organisms are therefore less likely to increase parental effort when environmental conditions deteriorate. To investigate the effect of decreased foraging capacity on parental behaviour of long-lived monogamous seabirds, we experi...

The current pilot study aimed at providing an initial assessment of how anxiety influences police officers' shooting behavior. Seven police officers participated and completed an identical shooting exercise under two experimental conditions: low anxiety, against a non-threatening opponent, and high anxiety (HA), against a threatening opponent who occasionally shot back using colored soap cartri...

Twelve years ago I wrote an annotation for this journal entitled 'The handicapped school leaver'.1 I pointed out what many knew and Warnock has so clearly stated that 'the transition from school to adult life can be difficult for many young people. For those with special educational needs it is likely to be a period of particular stress'.2 I lamented the loss of an extra year in education which...

Assessment and management of visual disorders in children with physical and/or intellectual impairment present a complex challenge to the clinician. A comprehensive review of all aspects of vision care in multiply handicapped children is too diverse to address in a single review. This review will focus on the techniques which have been developed for visual acuity assessment in this challenging ...

Rats with X-irradiation-produced degranulation of the hippocampal dentate gyrus were trained in the acquisition and reversal of simultaneous visual and tactile discriminations in a T-maze. These experiments employed the same treatment, apparatus, and procedure but varied in task difficulty. In the brightness and roughness discriminations, the irradiated rats were not handicapped in acquiring or...

A simple simulator for evaluating the physical capabilities of severely handicapped prospective drivers was developed and evaluated. The simulator presents a two-dimensional tracking task to be carried out using the driving controls of the Scott van, which is a uni-lever servo-controlled vehicle designed for the severely impaired. Twenty-five able-bodied subjects were tested on the simulator an...
