Discusses the ethical and legal aspects of confidentiality for Canadian psychologists, with particular emphasis on clinical psychology. The concepts of confidentiality, privileged communication, and privacy are clarified. The law of privileged communication in Canada is presented. Ethical standards, provincial and federal legislation, and case law bearing on confidentiality in clinical practice are discussed. Issues of mandatory child abuse reporting, the duty to protect, informed consent, and 3rd-party and client access to records are explored. Suggestions are made to the psychologist regarding the management of confidentiality. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Elders exposed to either progressive or imaginal relaxation procedures reported significant relaxation effects and showed improvement on measures of personal functioning. The results of the Physical Assessment Scale of the Relaxation Inventory indicated that relaxation responses were acquired within and across sessions. Large, consistent changes in relaxation occurred in all 4 sessions. The Symptom Checklist-90—Revised, which measures self-reported personal adjustment, showed significant positive changes following relaxation training and at 1-mo follow-up. Elders who imagined muscle tension release profited as much as those engaged in actual muscle tension-release activities. This finding is of importance for older adults who may experience physical limitations that contraindicate muscle-tension-release procedures.

The aim of this study was to determine whether metacognitive strategy training in the use of rime spelling units would be an effective intervention strategy for children with reading disability. Thirty-six disabled readers were randomly assigned to 1 of 2 training groups, a rime analogy training group or an item-specific training group. Posttreatment measures were taken at the completion of the training, and 1-year follow-up data were obtained from the 2 training groups and a sample of 20 normally developing readers. Systematic strategy training in the use of rime spelling units produced generalized achievement gains and transfer to uninstructed materials and was more effective than training that focused on item-specific learning and sentence-level strategies. The superior posttreatment performance of the rime analogy group over the item-specific group was maintained. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

A twin study of cognitive function in chronic fatigue syndrome: The effects of sudden illness onset.

Variable reports of neuropsychological deficits in individuals with chronic fatigue syndrome (CFS) may, in part, be attributable to methodological limitations. In this study, these limitations were addressed by controlling for genetic and environmental influences and by assessing the effects of comorbid depression and mode of illness onset. Specifically, the researchers conducted a co-twin control study of 22 pairs of monozygotic twins, in which 1 twin met strict criteria for CFS and the co-twin was healthy. Twins underwent a structured psychiatric interview and comprehensive neuropsychological assessment evaluating 6 cognitive domains. Results indicated that twin groups had similar intellectual and visual memory functioning, but fatigued twins exhibited decreases in motor functions (p = .05), speed of information processing (p = .02), verbal memory (p = .02), and executive functioning (p = .01). Major depression did not affect neuropsychological functioning among fatigued twins, although twins with sudden illness onset demonstrated slowed information processing compared with those with gradual onset (p = .01). Sudden onset CFS was associated with reduced speed of information processing. If confirmed, these findings suggest the need to distinguish illness onset in future CFS studies and may have implications for treatment, cognitive rehabilitation, and disability determination.

Two experiments examined whether or not readers obtain useful information from below the currently fixated line. In Exp 1, 15 adults read passages of text, and the availability of visual information below the line fixated was manipulated using a variant of the moving window technique. Reading was no slower when there was no letter information below the fixated line than when there was full information below the fixated line. However, a condition that made the strings of letters below the fixated line less wordlike caused reading to be slowed down by about 6%. In Exp 2, 15 adults searched for a target word through passages of text. There was no clear evidence that the availability of information below the line made search more efficient. It appears that in reading, little visual information is extracted below the line of text fixated. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

For many potential applications of fuel cells, especially road transport, it is highly desirable to use liquid fuels. In this paper it is shown that whether direct fuel cell systems (methanol/air) or indirect, hydrogen reformer to hydrogen are chosen, catalyst performance and cost plays a dominant role in the overall design. Notably, the maximum current densities which can usefully be employed are limited by the conductivity of low cost intercell plates in bipolar designs. Thus to attain respectable volume power densities, thin cell stack designs are essential. Considerations of overall simplicity, cooling and water control together with the need to operate at atmospheric pressure because of the cost, noise and inefficiency of air compressors all favour operating at 100°C or below. Although a number of systems could be constructed with known technology, costs are still too high for all but specialised applications. While useful engineering design work can be done using existing catalysts, present costs are far too high to justify widespread application. The recent discovery in the authors' laboratory of a base metal catalyst for the electrolytic oxidation of methanol together with past workers who have presented data on effective non-platinum air cathodes in acid electrolytes suggest that the quest is worthwhile. Bearing in mind the need to reduce total costs, while some system engineering development is worthwhile to provide solutions to the various physical problems involved, the authors argue that the primary effort on fuel cells should be in the fields of catalysis and electrode structure. 相似文献

Cassava varieties Iapar 19 – Pioneira (short cooking time, domestic vegetable), Taquari (medium-to-long cooking time, domestic vegetable), and Branca de Santa Catarina (long cooking time, industrial vegetable), were selected in order to investigate the cell wall and compositional basis for these textural differences. Pioneira had lower levels of Ca2+ and Mg2+, and higher levels of phytic acid and monovalent cations than the longer cooking time varieties. Detailed cell wall analysis indicated that the longer cooking Branca cultivar had higher levels of chelator-insoluble pectic polysaccharides. The potential causative roles of these different features were evaluated using vortex-induced cell separation (VICS) studies. Time to achieve the complete VICS of Branca cultivar was reduced to that of Pioneira with externally-supplied chelating agents (CDTA) and Na2CO3. Taquari roots did not respond in this way indicating a different biochemical basis for the maintenance of cell adhesion. The results are discussed in relation to the thermal stability of texture in these cassava varieties. 相似文献

Polarised ESR signals, observed from silicon-centred radicals produced by irradiation of either di-tert butyl peroxide or acetone in the presence of a silicon hydride, are presented and analysed. The novel feature that radical pair mechanism CIDEP can be used to accentuate weak sidebands due to radicals containing rare isotopes (here 29Si) is demonstrated. Adduct radicals formed by reaction with maleic anhydride and vinyltrimethylsilane were also studied. With the former, the adduct produced and observed in early-time experiments remains the same at room temperature and above; in steady-state studies this has been reported not to be so. 相似文献
