These findings were subsequently confirmed elsewhere (Barbeau, 1985;25 Tanner, 1985). Analysis of all early age onset IPD (EPD) cases born and raised in Saskatchewan(More)

While several cities have implemented these naloxone programs, little research has investigated officer attitudes about their training. The present research attempts to fill this gap by analyzing survey data from police officers following(More)
Smooth pursuit during prolonged occlusion is improved in the presence of sensorimotor signals when tracking self-generated target motion. The current study investigated whether concurrent arm tracking of externally-generated target motion conveys a similar facilitation to ocular pursuit of transiently occluded constant velocity (Experiment 1) or(More)

When microdialysis (MD) is used to study dermal delivery by iontophoresis, the effects of current may alter MD recovery through an increase in temperature, a change of pH, hyperemia, and dermal hydration. The objective of this work is to assess whether these effects of current may cause a measurable change in the retrodialysis of a model compound (sodium(More)
