The purpose of this project was to determine if commercially available braces could be shown to produce objective evidence of medial stabilization of the knee. Commercially available athletic braces were evaluated for their effect on abduction forces applied to a cadaver knee with no instability and with experimentally created medial instability. Under computer control, abduction forces were applied while simultaneous data were obtained from an electrogoniometer and transducers applied to the anterior cruciate ligament and the superficial medial collateral ligament at 0 degrees, 15 degrees, and 30 degrees of flexion. Our results showed a reduction in abduction angle using functional braces, whereas prophylactic braces demonstrated little or no protective effect.
In the context of a university in a developing country, large class size and inadequate studio space have become the bane of graphic design educators. Students go through the process of ideation with limited lecturer-student interaction. The problem has been compounded by the introduction of information and communication technology (ICT), which should be used as an advantage rather than a menace, since educators are not clear with the right pedagogy for ideation. This paper discusses the application of activity theory as a lens, in analysing the process of ideation as a way of looking at distortions in the current pedagogy. It concludes with the conviction that ICT has radically changed students learning practice. Educators need to find a way of tackling this, especially when large classes seem to be emerging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
