Perspectives on bilingual education in canada.

Bilingual education is considered in the context of education as a whole and of communication between people of different languages. It is argued that bilingualism cannot be legislated and that the importance of language in the Canadian French-English question has been overestimated. The schools, teachers, and students are considered in relation to an educational programme for bilingualism. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Long term medical costs of motor vehicle casualties in Alberta (1999): a population-based, incidence approach

The purpose of this paper is to estimate the long term medical costs attributable to motor vehicle accidents (MVAs) for all persons in Alberta, Canada in 1999, primarily using observational data. Injury claims with personal identifiers for 1999 were reported by the automobile insurance companies. These records were linked to the provincial health registry which covers the entire population. The registry is linked to databases which identify all inpatient and outpatient (including emergency room) visits, physician services, and other health records. Utilization and costs were derived for all casualties who were admitted to hospital or seen in an emergency room, and for a large sample of other (low severity) cases; a sample of matched controls was derived and their costs were also estimated. Actual costs were obtained for 3 years, and longer term costs were projected for subsequent years. Total costs attributable to MVAs were estimated at over $117 million for 1999. Average net costs per casualty, reported by severity group, were: $22.9 thousand for hospital cases; $3.6 thousand for emergency room – only cases; and $157 for other cases. Long term costs were 65% of first year costs for hospitalized cases and 250% for emergency room cases. Overall, aggregate costs for all non-hospital cases exceeded those for hospitalized cases.     

Review of Women and the chip: Case studies of the effect of informatics on employment in Canada.

Reviews the book, Women and The Chip: Case Studies of the Effect of Informatics on Employment in Canada by Heather Menzies (1981). Women and the Chip looks at the effects that the new technology of informatics (the marriage of computers and telecommunications) is having and will continue to have on the structure of the labour force-particularly women. The changing employment patterns and practices related to this new technology will change many jobs and eliminate many others as office work becomes as automated as car assembly was in years past. To help the reader develop an appreciation of the scope of this change four major case studies are presented: a large corporate head office, a major insurance company, chartered banks, and supermarkets (all industries with a heavy concentration of women employees). The book is well written, well organized, thorough and informative "Blueprint for the future". The book should be read by everyone out of general interest, but especially for psychologists involved with vocational planning and decision making.

NRC Clients' Perceptions of Electronic Resources and Use of CISTI's Virtual Library

ABSTRACT

This article presents results relating to perception and usage of CISTI's two-year-old Virtual Library in a research environment. Research and technical officers of the National Research Council of Canada were surveyed. The results indicate that research staff are favorably inclined toward the use of electronic resources, with some differences accorded to its use by the two client groups studied. Surprisingly, research staff accept the possibility of serendipity in a digital environment. There is a positive correlation between usage of digital resources and perception and training levels, while a correlation between presence of an onsite traditional library with usage of electronic resources is not supported. Data collected will be used to assist in the redesign of the site and related training efforts.     

Review of Canadian mental health law and policy.

Reviews the book, Canadian Mental Health Law and Policy by John E. Gray, Margaret A. Shone, and Peter F. Liddle (2000). The authors of this book have produced a multidisciplinary text that succinctly summarizes the main points of Canadian mental health laws and the variability across provinces and territories in these laws and in their typical interpretation and application. This book offers a concise guide to the laws dealing with key issues such as involuntary hospital admission, authorization of psychiatric treatment, and treatment refusal. Although not always an easy read for those unfamiliar with legal terms and writing, the book is geared to a wide audience that includes legal and policy specialists, mental health professionals, and advocates for the mentally ill. These authors are to be congratulated for their efforts to disseminate and explain information on Canadian mental health law and to promote a more humane and scientifically grounded set of legal standards and interpretations that are pertinent to the disposition and treatment of Canadian citizens with severe mental disorders.

Editorial

Ozone applications in Canada began in 1954 and have shown continuous growth with the largest installation at the Charles des Baillets drinking water plant in the city of Montreal. Many systems have been installed for treatment of swimming pools, odor control and, in particular, cooling towers. One of the world's largest cooling tower applications is at the Alberta Natural Gas Plant. The use of ozone is expected to continue to grow.     

A survey of Legionella pneumophila in water in 12 Canadian cities

A survey of 12 cities across Canada was conducted in order to determine the prevalence of Legionella species in potable water and cooling tower water within buildings. Legionellae were detected in 11.9% of the samples overall: 6.7% from potable water sources and 28.9% from cooling tower water. The maximum concentration of the organism was 45,000 l⁻¹ in one shower-water sample by culture methods. A significant difference in the isolation rate of Legionella pneumophila among cities was observed. The organism was isolated from waters at a temperature of 15–41°C and was most frequently isolated in the 20–29°C range. The concentration of free and total available chlorine in the water was not associated with legionellae recovery except that the organisms were never recovered when the free available chlorine residual exceeded 7.5 mg l⁻¹. Although L. pneumophila were in low concentrations or absent in most samples, the isolated organisms were usually serogroups 1 or 6, the same serogroups that are most often implicated in legionellosis cases in Canada.
