The prevalence of noise-induced hearing loss (NIHL) in current motorcycle grand prix racers was investigated. A total of 44 riders was randomly recruited and underwent interview, otological examination and pure tone audiometry. The median age was 28 (range 18-37) years and median racing experience was 10 (range 2-21) years. Twenty riders (45%) had hearing losses greater than expected for age ma...

OBJECTIVE To investigate the possible influences of saddle type on the incidence of "lower back pain" in a cross section of equestrian riders. METHODS 108 equestrian riders completed a questionnaire concerning their riding habits and whether they suffered from lower back pain. In particular they were asked whether they used a traditional style/general purpose saddle (GP) or a deep seated/West...

BACKGROUND All-terrain vehicles (ATVs) have gained in popularity in recent years, and this rise in use has been accompanied by increases in the number of ATV-related injuries. Because children often lack the physical strength, cognitive abilities, and fine motor skills to operate ATVs properly, their risk for injury is greater. Furthermore, most children ride adult-sized ATVs. OBJECTIVES To e...

The recent boom in the demand for off-highway vehicle (OHV) recreation has created an important policy issue for public land managers who are concerned with the impacts of OHV use on environmental quality. Within the past few years, the U.S. Forest Service has recognized the need for greater authority in managing these recreation areas and has proposed to amend OHV regulations. However, not muc...

This paper presents a solution for reducing the ill effects of free-riders in decentralised unstructured P2P networks. An autonomous replication scheme is proposed to improve the availability and enhance system performance. Q-learning is widely employed in different situations to improve the accuracy in decision making by each peer. Based on the performance of neighbours of a peer, every neighb...

Since the ability to train the horse to be ambidextrous is considered highly desirable, rider asymmetry is recognized as a negative trait. Acquired postural and functional asymmetry can originate from numerous anatomical regions, so it is difficult to suggest if any is developed due to riding. The aim of this study was therefore to assess symmetry of posture, strength and flexibility in a large...

Uber is a popular ride-sharing application that matches people who need a ride (or riders) with drivers who are willing to provide it using their personal vehicles. Despite its growing popularity, there exist few studies that examine large-scale Uber data, or in general the factors affecting user participation in the sharing economy. We address this gap through a study of the Uber market that a...

This study assessed the degree to which hazardous vignettes are perceived as dangerous and realistic by car drivers and motorcycle riders (Exp. 1) and whether riders could be distinguished from drivers on their performance in a commercial motorcycle simulator during safe and hazardous riding situations using the same hazards (Exp. 2). In Experiment 1, car drivers and motorcyclists received a qu...

Motorcycle riding is a hobby commonly enjoyed by Americans with nearly 8.5 million registered motorcycles in the US [1]. Motorcycle manufacturers have enjoyed consistent increases in sales throughout the first decade of the 21st century [2], an indication that the sport is gaining avid new riders each year. An important consideration as sales increase is the demographics of the riders themselve...

Risk-taking behaviour by motorcyclists has been shown to contribute to a substantial proportion of road crashes in Australia and abroad. Concern has been expressed that traditional motorcycle licence training programs do not sufficiently address such behaviour. Accordingly, the Three Steps to Safer Riding program was developed to address risk taking behaviour by riders as an adjunct to existing...
