Equations and charts for the rapid estimation of hinge-moment and effectiveness parameters for trailing-edge controls having leading and trailing edges swept ahead of the Mach lines

Existing conical-flow solutions have been used to calculate the hinge-moments and effectiveness parameters of trailing-edge controls having leading and trailing edges swept ahead of the Mach lines and having streamwise root and tip chords. Equations and detailed charts are presented for the rapid estimation of these parameters. Also included is an approximate method by which these parameters may be corrected for airfoil-section thickness

Homelessness Coverage in Major Canadian Newspapers, 1987 – 2007

This article describes how the Canadian printed news media depicted the homeless and their situations between 1987 and 2007. Our study used a descriptive, cross-sectional design and a content analysis was conducted on selected newspaper articles on homelessness issues. The main themes were housing-related issues, profiling of homelessness, health-related issues, economic factors, illegal activities, community aid and support, and social factors as cause of homelessness. Housing related issues, community aid and support, profiling of homelessness and economic factors were addressed in 85.3% of the stories. This study provides a retrospective examination of the media’s interests in and portrayal of the homeless and homelessness issues
