Although concurrency is generally perceived to be a ‘hard’ subject, it can in fact be very simple — provided that the underlying model is simple. The occam-π parallel processing language provides such a simple yet powerful concurrency model that is based on CSP and the π-calculus. This paper presents pony, the occam-π Network Environment. occam-π and pony provide a new, unified, concurrency mod...

Pony Club is one of the leading junior equestrian organisations in the world, and was established to teach young people the many aspects of horsemanship. The aim of this study was to gain an understanding of the health and performance of Pony Club horses from the perspective of their owners. In-depth interviews were conducted with Pony Club members at two sites in Australia, and topics relating...

Ponies with tracheal collapse may have an increased anesthetic risk due to airway obstruction during induction and recovery. To our knowledge, there are no anesthetic descriptions of these patients, despite a reported 5.6% incidence and 77% mortality rate. Two Shetland ponies with tracheal collapse, a 12-year-old male (pony 1) and a 27-year-old female (pony 2), were referred for right eye enucl...

this study describes the prevalence of cardiac dysrhythmias occurring over a single 24 h period in ponies and compares the heart rate and frequency of dysrhythmias in two groups of ponies of different ages. electrocardiograms were recorded using a holter monitoring system from twenty four ponies aged less than 15-year-old (n = 14) and greater than 15-year-old (n = 10). subsequent analyses of ca...

The purpose of this study was to evaluate the variation in plasma adrenocorticotropic hormone (ACTH) concentration and dexamethasone suppression test (DST) results with season, age, and sex in healthy, pony mares (n=15) and pony stallions (n=14) living under semiferal conditions and horse mares (n=10) living at pasture. Plasma ACTH concentrations were measured in September 2002, and in January,...

Pony riding can give a new dimension to the life of a handicapped child.

This paper will consider the ways in which children take part in two distinct branches of horse sport, equestrianism and horseracing, focusing on their historical separateness and their more recent rapprochement through the development of pony racing. Using material from a recent study of children and horseracing, it will demonstrate that most racecourses still see youngsters as passive consume...
