Geropsychology training in Canada: A survey of doctoral and internship programs.

The Canadian Psychological Association emphasises the importance of diversity training for doctoral and internship programs, and age is an important aspect of diversity. Yet, little is known about training capacity in clinical geropsychology in Canada. To address this issue, the authors surveyed directors of clinical training in all accredited clinical and counselling psychology doctoral and internship programs in Canada. Responses from 92% (n = 43) of these programs indicated that there are no doctoral programs in Canada with a formal concentration in geropsychology; however, 40% of internships offer a major rotation in geropsychology and a further 48% offer a minor rotation. Training activities are largely focused on the diagnosis and assessment of mental health problems, with relatively less attention to therapeutic interventions. Data are presented on the availability of geropsychology resources (e.g., faculty/clinical supervisors, courses, practicum, research opportunities) and the perceived need for geropsychology training. Recommendations for enhancing geropsychology training capacity in Canada are reviewed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Diffraction evidence for distorted graphite-like ribbons in an activated carbon of very large surface area

A carbon prepared from petroleum coke which possesses a very large active surface area (3500 m²/gm) has been examined with X-ray diffraction techniques. Simultaneous analysis of the low and high angle scattering suggests that the material is composed of distorted ribbons of graphite-like layers. On the average, each ribbon contains only one or a very few graphite-like layers, and these layers are distorted with an average radius of curvature of ~ 25A. This very open structure results in a large surface area and gives rise to extensive small angle scattering.     

Morphology of surface crystallites on amorphous Fe87Zr7B5Cu1

Surface crystallites a few tens of nanometres in breadth have been observed on the as-melt-spun surface of an alloy of compositionFe ₈₇ Zr ₇ B ₆ Cu ₁. These crystallites are preferentially oriented, and exhibit a (2 0 0) texture. Heat treatments at temperatures in the interval 623–773 °C caused the surface grains to coarsen and new, randomly oriented crystals to form. Compositional inhomogeneities were found to contribute to the formation of the surface crystallites. Results suggest that surface energy effects are more important during the nucleation of crystallites in the liquid than they are below the glass transition temperature.
