The Value of Refining a Threshold Concept

In the summer of 2012, I had the privilege of attending the Backwards By Design workshop, where I was introduced to the “threshold concept” (Cousin, 2006). I learned how the use of this approach could shift the ontological and conceptual dimensions of students’ perspectives. That fall, I implemented the threshold concept into my undergraduate CSD 401 Writing Lab. My intention was for students to gain perspective into the lives of survivors of acquired brain injuries. I hoped the assignment would help them develop empathy for the types of clients they would work with one day as burgeoning speech-language pathologists

Cognitive-Motor Interference During Functional Mobility After Stroke: State of the Science and Implications for Future Research

Cognitive-motor interference (CMI) is evident when simultaneous performance of a cognitive task and a motor task results in deterioration in performance in one or both of the tasks, relative to performance of each task separately. The purpose of this review is to present a framework for categorizing patterns of CMI and to examine the specific patterns of CMI evident in published studies comparing single-task and dual-task performance of cognitive and motor tasks during gait and balance activities after stroke. We also examine the literature for associations between patterns of CMI and history of falls, as well as evidence for the effects of rehabilitation on CMI after stroke. Overall, this review suggests that during gait activities with an added cognitive task, people with stroke are likely to demonstrate significant decrements in motor performance only (cognitive-related motor interference) or decrements in both motor and cognitive performance (mutual interference). In contrast, patterns of CMI were variable among studies examining balance activities. Comparing people post-stroke with and without a history of falls, patterns and magnitude of CMI were similar for fallers and non-fallers. Longitudinal studies suggest that conventional rehabilitation has minimal effects on CMI during gait or balance activities. However, early phase pilot studies suggest that dual-task interventions may reduce CMI during gait performance in community-dwelling stroke survivors. It is our hope that this innovative and critical examination of the existing literature will highlight the limitations in current experimental designs and inform improvements in the design and reporting of dual-task studies in stroke

Web 2.0 in der akademischen Praxis: Herausforderungen und strategische Optionen

Das Web 2.0 hat die Kommunikation verändert. Dies gilt zum einen für die Kommunikation im Alltag, für die inzwischen knapp ein Drittel aller Internetnutzer in Deutschland regelmäßig auf Web 2.0-Angebote zurück greifen (Busemann & Gscheidle, 2010). Dies gilt aber auch für die Kommunikation im Hochschulkontext, wo das Web 2.0 von Seiten der Studierenden wie der Hochschulen in den Bereichen Lehre, Forschung und Verwaltung und Dienstleistungen genutzt wird (Hochschulrektorenkonferenz, 2010)
