The aim of this study was to compare assessments made by Finnish- and Swedish-speaking workers in Finland about the safety climate in their companies, because an earlier study showed that the accident frequency of Swedish-speaking workers was one third lower than that of Finnish-speaking workers. 148 Finnish-speaking and 138 Swedish-speaking workers from 14 small and medium-sized companies participated in this study. They filled out a Finnish safety climate questionnaire, the reliability of which was above the acceptable level. There were no differences between the language groups in the total variables of safety climate and safety action. Based on the differences in single items, we interpreted that Swedish-speaking workers stressed collective safety more, whereas Finnish-speaking workers put more emphasis on their personal responsibility for safety. 相似文献

Summary. Ecological and phylogenetic factors determine which sensory modalities organisms use in their day-to-day activities. Among
lizards, empirical studies indicate a tight association between foraging strategies and the ability to detect chemical cues
from prey. Consequently, ambush insectivores do not detect food chemicals and these differences have a phylogenetic basis,
as ambush lizards mainly belong to the Iguania clade. These data contrast, however, with the widespread uses of chemoreception
in the Iguania genus Liolaemus, which are mostly insectivorous ambush predators. Moreover, observations from different Liolaemus species suggest a capability to find prey through chemoreception. In order to clarify the abilities of Liolaemus to detect chemical cues from prey, the chemoreceptive behavior of the insectivorous ambush predator, L. lemniscatus, was studied. Lizards were given the choice between areas with and without chemical cues from a food item (mealworms). Results
show that test animals stayed for longer, moved more, and did more chemical exploration (tongue flicks) in the area where
chemical cues from mealworms were present. Furthermore, in this area, more individuals displayed behaviors that suggest maintenance
and defense of the prey patch. Thus, L. lemniscatus is the first insectivorous Iguania reported to be able to detect chemical cues from prey. Although I propose a mechanism
for acquiring chemical detection of prey cues in Liolaemus, I also remark that it is necessary to reanalyze both the abilities to detect and use chemical foraging cues in Iguania at
large, and the methodologies traditionally used to study these issues. 相似文献

Cysts located on the tongue are rare and usually diagnosed in childhood. Here we report on the prenatal diagnosis of an unusual cystic malformation of the tongue with heterotopic intestinal tissue explored by prenatal ultrasound, magnetic resonance imaging and on its surgical treatment and histological examination. The prenatal differential diagnoses as well as perinatal management of cystic lesions of the tongue are reviewed. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献
