Adolescents at the skatepark: identifying design features and youth behaviours that pose risk for falls.

Background: Skateboarding is an increasingly popular leisure activity for youth, yet injuries due to falls are common. This study aimed to identify the features at skateparks and tricks performed by youth that pose an increased risk of falls in skateboarders.

Method: Video recordings were unobtrusively taken at a large skatepark of youth designated as young (11-15 years) or old (16-20 years).

Examining how different measurement approaches impact safety outcomes in child pedestrian research: Implications for research and prevention.

There has been a great deal of research aimed at understanding the causes of child pedestrian injury. Many different methods have been employed with the goal of designing simulations that produce rigorous assessment of children's behaviors without putting children at risk of actual pedestrian injury. Most research has assessed children's pre-crossing decision making and extrapolated crossing outcome measures from estimates of mean walking speed.

Design, synthesis, and characterization of novel, nonquaternary reactivators of GF-inhibited human acetylcholinesterase.

The goal of this research was to identify structurally novel, non-quaternarypyridinium reactivators of GF (cyclosarin)-inhibited hAChE that possess the capacity to mediate in vitro reactivation of GF-inhibited human acetylcholinesterase (hAChE). New compounds were designed, synthesized and assessed in GF-inhibited hAChE assays. Structure activity relationships for AChE binding and reactivation of GF-inhibited hAChE were developed.

Examining parents' behaviors and supervision of their children in the presence of an unfamiliar dog: does The Blue Dog intervention improve parent practices?

Objectives: Young children are at particular risk for dog bite injuries. This study examined parents' supervision of and reactions to their children in the vicinity of an unfamiliar dog.

Methods: A pre/post intervention/control group randomized design assessed whether exposure to The Blue Dog, a dog bite prevention and education program, positively impacted parent behaviors.

A measure that relates to elementary school children's risk of injury: the supervision attributes and risk-taking questionnaire (SARTQ).

Objectives: The aim of this study was to examine the psychometric properties of the supervision attributes and risk-taking questionnaire (SARTQ), which is a new measure of caregiver supervision and child risk-taking that applies to elementary school children 7-10 years of age.

Methods: Using a prospective design, scores on the SARTQ were related to children's recent and long-term history of injuries and to parents' supervision scores that were derived based on measuring their home supervision practices over 8 weeks.

Results: Subscale scores on the SARTQ related differentially to measures of supervision and child injury scores, providing support for the criterion validity of this new measure.
