This survey determines the dental care needs of hospitalized adults with psychiatric and mental disorders. Comprehensive clinical and radiographic oral examinations, conducted on 33% of the patients in a large state mental hospital, found that extensive unmet needs existed in this population. The major requirements were for prophylaxis, calculus removal, and periodontal therapy. The patients' needs varied depending on several demographic factors, including length of hospitalization and psychiatric diagnoses.
The use of negative probabilities is discussed for certain problems in which a stochastic process approach is indicated. An extension of probability theory to include signed (negative and positive) probabilities is outlined and both philosophical and axiomatic examinations of negative probabilities are presented. Finally, a class of applications illustrates the use and implications of signed probability theory.
This article provides an overview of the Nisga'a Final Agreement (the Treaty), the first comprehensive claims agreement to include recognition of the inherent right of self-government and constitutional protection of this right. This right is of long history to the Nisga'a people (as evidenced by a brief review of the 1913 Petition), to the Nisga'a Final Agreement, and, ultimately, to our defence of the Treaty against the legal challenge to the self-government provisions by Gordon Campbell (then leader of the opposition in the British Columbia legislature, now Premier of BC). It is this consistent thread in respect of the importance of self-government which has defined the Nisga'a approach to treaty making with the federal and provincial governments. Moreover, the Treaty also represents a unique example of legal pluralism whereby a distinct system of law making and governance successfully and peacefully operates within and in accordance with the constitutional framework of the Canadian State.
The fundamental economic and institutional constraints to energy development reside in the obstacles to siting large mining and conversion facilities. These obstacles are of three varieties:(1) industry risks; (2) the problems of satisfying federal planning procedures and environmental impact standards; and (3) the inadequacies of the socioeconomic environments supporting the industry. Industry risks have been widely discussed (see Henry et al., 1973) as have the problems of satisfying environmental standards and planning procedures (Federal Energy Administration, Office of Finance and Energy, 1977). This paper summarizes the limitations on energy production and utilization flowing from the siting of new facilities in inadequate socioeconomic settings. In the first part, the effects of siting new energy facilities in areas having limited assimilative capacities are described in detail. These effects are shown to be part of a self-perpetuating cycle of social, economic, and institutional morbidity that both imposes burdensome public costs on the host community and greatly diminishes productivity
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
