BACKGROUND Functionally related genes tend to be correlated in their expression patterns across multiple conditions and/or tissue-types. Thus co-expression networks are often used to investigate functional groups of genes. In particular, when one of the genes is a transcription factor (TF), the co-expression-based interaction is interpreted, with caution,(More)

Animals that forage in groups have access to social information concerning the quality and location of food resources available. The degree to which individuals rely on social information over their own private information depends on a myriad of ecological and social factors. In general, where resources are patchy in space and/or time, individuals that use(More)
Groups of animals are often heterogeneously structured and may be composed of selfish individuals responding to different internal stimuli. Group-level behaviour can be determined by the slight differences in simple behavioural movement parameters structuring local interactions between conspecifics. To accurately understand individual behaviour within(More)
OBJECTIVE Prehospital emergency medical services (EMS) providers report anxiety as the second most common contributor to paediatric patient safety events. The objective of this study was to understand how EMS providers perceive the effect of stress and anxiety on paediatric out-of-hospital patient safety. SETTING This was a nationwide study of EMS(More)
OBJECTIVE To describe the frequency and characterise the nature of patient safety events in paediatric out-of-hospital airway management. METHODS We conducted a retrospective cross-sectional medical record review of all 'lights and sirens' emergency medicine services transports from 2008 to 2011 in patients <18 years of age in the Portland Oregon(More)
INTRODUCTION The association between geographic factors, including transport distance, and pediatric emergency medical services (EMS) run clustering on out-of-hospital pediatric endotracheal intubation is unclear. The objective of this study was to determine if endotracheal intubation procedures are more likely to occur at greater distances from the(More)
