The Euro-Barometer values battery has provided much of the empirical evidence for the thesis that a shift from materialist to postmaterialist values has occurred in advanced industrial societies over the past two decades. It has been argued, however, that this widely used instrument is seriously flawed because of its sensitivity to current economic conditions. We present data from experiments in Canada and Germany that tested the performance of the values battery in an era of joblessness. Analyses reveal that (1) substituting an unemployment statement for the standard inflation statement in the battery has major consequences for the classification of respondents as materialist or postmaterialist and (2) answers to the battery are conditioned by the interaction between its content and respondents' economic issue concerns. These findings support the argument that much of the shift from materialist to postmaterialist values recorded by the Euro-Barometer since the early 1980s is a measurement artifact.

This study uses 1990 Canadian national survey data to investigate public beliefs about democracy and how these affect satisfaction with the opera tion of an existing democratic political system. Confirmatory factor analyses reveal that conceptions of democracy are structured in terms of four factors- security, opportunities, elections-capitalism, and equality of group influence. All four factors affect levels of democracy satisfaction, controlling for several other influential variables. Consistent with the long-standing, but largely un tested, congruence hypothesis, Canadians whose beliefs about democracy tend to be consistent with the realities of political life in their country are more satisfied than are those whose beliefs accord less well with prevailing practices.

Terrorist attacks in crowded places cause multiple casualties that are evacuated by quick succession to nearby hospitals. The study goals were to analyse the issues of patient misidentification and excessive blood request and to develop recommendations for the management of such episodes. A retrospective analysis of nine explosion attacks was performed. In nine consecutive events, 450 casualties were reported by the National Ambulance Service, 82 of whom (18%) died on the explosion site and 368 were admitted to nearby trauma centres. Red blood cell units were typed and cross-matched for 70 patients. Seventy-three per cent of the blood supplied over the first 24 h was administered during the first 2 h. The cross-matched/transfused ratio was 2.52 +/- 1.42, reflecting the overestimation of blood requirement in mass casualty episodes. In the mass casualty setup, blood bank personnel should be alert to a potential mistransfusion or a blood collection error. Unidentified patients are subjected to errors due to only one-digit difference in their temporary identification number. Application of the system using an additional sequential four-digit number printed in bold and large size font for patients at admission reduced the possibility of misidentification. Modern technologies, including error-reduction design wristbands, barcode-based system or radiofrequency identification tags may also increase reliability of patient identification in the mass casualty setup.
