La1-xSrxMnO3 as a candidate for a room temperature pressure sensor /

Perovskite manganite compounds, Lai-xDxMnOs (D-divalent alkaline earth Ca, Sr or Ba), whose electrical and magnetic properties were first investigated nearly a half century ago, have attracted a great deal of attention due to their rich phase diagram. From the point of view of designing a future application, the strong pressure dependence of the resistivity and the accompanying effects in thin films have potential for application in pressure sensing and electronic devices. In this study we report our experimental investigations of pressure dependence of the resistivity of Lao.siSvo^iQMnOs and Lai-xSvxMnOs (LSMO) epitaxial films with x= 0.15, 0.20, 0.25, 0.30, 0.35, on SrTiOs substrates.

Examination of students' ability to observe domains of client behaviour in therapeutic recreation

When observing client behaviours, a therapeutic recreation specialist must have a base understanding of typical client behaviours to provide an informed analysis (burlingame & Blaschko, 2010). Providing students with the necessary tools for client observation is significant to the success of this process. The purpose of this study was to assess the relationships amongst the TR student demographic characteristics on acquiring the observation competency necessary to conduct a TR assessment. One hundred seventy-two TR college and university students, enrolled in post-secondary undergraduate TR programs across Ontario, observed a client assessment via video, and recorded their observations using the Tracking Behavioural Assessment (TBA) (Passmore, 2002). Independent samples t-tests and analysis of variance were calculated for the different student characteristics on the domains of the TBA. Significant findings indicated that university students scored more accurately than college students, and advanced students more accurately than novice students, on the emotional and socialization domains.
