Background: With the increasing awareness and action amongst stakeholders in addressing the concerning rise of unmatched Canadian Medical Graduates (CMGs), little is known from those who go unmatched. We use our unmatched experience to contribute to this dialogue. Methods: We present an issues-based examination of the matching process by reflectin...

Background: Given the history of unethical research in Indigenous communities, there is often apprehension among Indigenous communities toward research carried out by non-Indigenous researchers. We examined the approaches, experiences and motivations among non-Indigenous researchers at a research-intensive Canadian university conducting research w...

Hummingbirds are an emerging model for studies of the visual guidance of flight. However, basic properties of their visual systems, such as spatial and temporal visual resolution, have not been characterized. We measured both the spatial and temporal visual resolution of Anna's hummingbirds using behavioral experiments and anatomical estimates. Spa...

Significance Birds can steer a precise course at high speed, but little is known about how they avoid collisions with surrounding objects and the ground. We manipulated the visual environment of hummingbirds as they flew across a long chamber to evaluate how they use visual information for course control. We found that lateral course control is bas...

The sampling of spatial and temporal visual information for all living organisms is finite. The speed and accuracy of visual systems contributes in part to an animal's sensitivity to visual motion. The ability to see swift motions is a crucial adaptation among bird species, which are high-speed animals that navigate in a three-dimensional world. Hu...
