Reducing sedentary behaviour after stroke: perspectives of ambulatory individuals with stroke.

Purpose: Understanding the determinants of sedentary behaviour (sitting or lying with low energy expenditure) in stroke survivors can enhance the development of successful behaviour change strategies. This qualitative study explored the perceptions of stroke survivors about sedentary behaviour and ways in which it can be changed.

Methods: An interpretative qualitative inquiry was used with thematic analysis of interview data.

Theory-based research of high fidelity simulation use in nursing education: a review of the literature.

In this article, we explore the extent to which theory-based research is informing our understanding of high-fidelity simulation use in nursing education. We reviewed the primary literature archived in the Cumulative Index of Nursing and Applied Health Literature (CINAHL) and Proquest Dissertation and Theses for empirical reports using the key terms high-fidelity simulation and nursing from the years 1989 to 2009. Of the articles that matched our inclusion criteria: 45% made no use of theory; 45% made minimal use; and 10% made adequate use.

Red, distasteful water mites: did fish make them that way?

Water mites (Acari: Hydrachnida) are unusual among the typically cryptic freshwater fauna in that many species are brightly colored red or orange, and also appear to be distasteful to fish. This apparent aposematism (use of color to warn predators) has been previously explained as the evolutionary end-product of pressure from fish predation. The fish-predation argument has been supported by observations that fish spit out red mites, powder made from red water mites is more distasteful to fish than powder made from non-red mites, and red mites appear to be more abundant than non-red mites in water bodies where fish are present.
