Immediate effects of postural repositioning on maximum phonation duration tasks in seated individuals with acquired dysarthria: a pilot study.

Purpose: To determine the effectiveness of a single 10-min postural repositioning session on the maximum phonation duration (MPD) of the vowel/a/in individuals with acquired dysarthria.

Materials And Methods: A pre-post interventional design was implemented; five patients with dysarthria (PWDs) underwent a single 2-hour experimental session. MPD capacities were assessed before and immediately after a 10-min postural repositioning intervention by a physical and occupational therapist.

Big Science vs. Little Science: How Scientific Impact Scales with Funding.

is it more effective to give large grants to a few elite researchers, or small grants to many researchers? Large grants would be more effective only if scientific impact increases as an accelerating function of grant size. Here, we examine the scientific impact of individual university-based researchers in three disciplines funded by the Natural Sciences and Engineering Research Council of Canada (NSERC). We considered four indices of scientific impact: numbers of articles published, numbers of citations to those articles, the most cited article, and the number of highly cited articles, each measured over a four-year period.
