OBJECTIVES To determine the changes, since 1980, in the number of nontreated caries in elderly people who have retained their teeth and are in residential and long-term care centres (CHSLDs) in the province of Quebec, Canada, and the changes in their perception of their oral health problems and use of dental services. METHODS A secondary analysis of data from a 2004-2005 survey about the oral...

Since Geert Hofstede's Culture's Consequences: International Differences in Work-Related Values (Sage, 1980) was published, researchers have utilized Hofstede's cultural values framework in a wide variety of empirical studies. We review 180 studies published in 40 business and psychology journals and two international annual volumes between 1980 and June 2002 to consolidate what is empirically ...

Interpolatory quadrature rules whose abscissas are zeros of a biorthogonal polynomial have proved to be useful, especially in numerical integration of singular integrands. However, the positivity of their weights has remained an open question, in some cases, since 1980. We present a general criterion for this positivity. As a consequence, we establish positivity of the weights in a quadrature r...

UNLABELLED Nearly thirty-five years have passed since Hackman published his "Check list of the Finnish Diptera" (1980). The number of true flies (Diptera) known from Finland has increased by more than two thousand species since then. At the same time, hundreds of erroneous records have been recognized and purged from the checklist. ZooKeys issue 441 provides a new checklist of the Diptera speci...

The ideas used in experiments today were mostly in place by the first few decades of the 20th century. The procedures of comparing groups, assigning individuals to treatments, and statistically analyzing group comparisons had been developed by 1940. During the 1960s, the types of experimental designs were identified and the strengths (e.g., control over potential threats) of these designs speci...

Since 1978 continuous intravenous infusion with Althesin has been used instead of barbiturates in the regime. Mortality rate fell from 83.7 percent (1970 1977) to 43.7 percent (1978 1980) for nonhead injury patients and from 72.1 percent (1970 1977) to 45.6 percent (1978 1980) in the headinjured group, the differences between the periods being statistically significant. The possible influencing...
