The inextricable and interdependent link between language identity has long been acknowledged (e.g. Joseph 2004; Norton 2000). Language is, after all, the means through which we identify oursel...

We consider the Norton algebra associated with a Q -polynomial primitive idempotent of adjacency matrix for distance-regular graph. obtain formula product that we find attractive.

BACKGROUND Pressure ulcers are a frequent complication of bed rest. We examined risk factors for hospital-acquired pressure ulcers, the use of preventive devices, and the impact of case-mix adjustments on between-ward comparisons. METHODS We conducted 3 cross-sectional surveys in a teaching hospital of 2373 patients who had no pressure ulcer on admission. We assessed the presence of pressure ...

BACKGROUND While there is scientific evidence to support the efficacy of preventive interventions for pressure ulcers, few empirical data are available on their cost-effectiveness. The aim of this study was to determine the cost-effectiveness of interventions to prevent pressure ulcers. METHODS Cost of preventive interventions and days of ulcer-free survival were compared for two groups of pa...

The objective of this study was to evaluate inter-rater reliability of Braden Scale, Norton Scale and Waterlow Scale for pressure ulcer risk assessment in clinical practice. The design of the study was cross-sectional. A total of 23 patients at pressure ulcer risk were included in the study, and 6 best registered nurses conducted three subsequent risk assessments for all included patients. They...

Aim: The aim of the review was to determine the predictive validity of selected pressure ulcer risk assessment scales. Prediction of a risk of pressure ulcers is a priority issue in nursing. In the foreign literature, there are currently lots of research studies dealing with the validity of pressure ulcer risk assessment scales. Methods: The data sources were articles in three licenced, free an...
