Why do people vote? An experiment in rationality 总被引:1,自引:0,他引:1
The study presents the findings of an experiment conducted during the 1993 Canadian fedeal election campaign. Students in two universities were exposed to a ten-minute presentation about the rational model of voting and the ‘paradox’ that so many people vote when it is apparently irrational on a cost-benefit basis. Our data indicate that exposure to the presentation decreased turnout in the election by seven percentage points. This result contributes to the debate abut the effect of rational-choice models on real political behavior. More important, the experimental panel data permit the presentation's effect to be decomposed, and this helps explain why people do vote. In this study, turnout was reduced mainly because the presentation diminished the respondents' sense of duty, an effect that was indirect, because there was no reference in the presentation to such motives. Framing the voting act in rational-choice terms induced some students to reconsider whether they should feel obliged to vote. 相似文献

In order to establish an animal model for entomotoxicological studies, the kinetics of morphine elimination from blood after a single intravenous injection of morphine and the concentration of morphine in tissues following a continuous perfusion were studied. The aim of these experiments was to obtain controlled morphine tissue concentrations similar to those encountered in fatal human heroin overdoses. These tissues can be used as a food source for developing fly larvae in entomotoxicological studies. In the single injection experiment, seven rabbits were administered 1 or 2 mg/kg body weight of morphine chlorhydrate via the main ear artery. Blood samples of 200 microL were removed regularly via a catheter. Morphine concentration was determined using RIA techniques. Morphine was found to be first rapidly distributed and then slowly eliminated, following a two-exponential equation. Elimination of morphine from blood can be described as a two-compartment model. Constants of the equation were determined using the Kaleidagraph program. Using those constants, the main pharmacokinetics parameters were calculated. Results of these parameters showed the following: clearance from 13.3 to 16.2 L.h.1, half-life of the distribution phase from 0.6 to 0.9 min, and half-life of the elimination phase from 21 to 26 min. These results were used to calculate the rate of perfusion of morphine for rabbits to obtain desired, controlled, and constant concentrations of morphine in tissues. In the second experiment, three rabbits received a perfusion of morphine intravascularly at a rate of 2 mg/kg/h for a period of 3 h. These rabbits were sacrificed and analyses performed on several abdominal and thoracic organs. Results showed that the concentrations of morphine differed according to the organ analyzed, but were reproducible for organs between animals. These concentrations were similar to those normally encountered in cases of human death due to heroin overdoses. 相似文献

Abstract: This study examines the use of influence tactics by Human Resources managers with the members of the Quebec public-sector management team. The results indicate that they use a large number of influence tactics, that they use more frequently “soft” tactics than “hard” ones or “neither soft nor hard” ones, and they choose their tactics based on a cost-benefit analysis. Furthermore, the analyses reveal that respondents whose feelings of self-efficacy are high will not attempt to influence or use “soft” tactics any more frequently than respondents with low feelings of self-efficacy. Finally, the results indicate that our respondents exercise influence effectively. 相似文献

Paraquat (gramoxone) poisoning in south-west Hungary, 1977-1984. Toxicological and histopathological aspects of group intoxication cases 总被引:1,自引:0,他引:1
L Harsányi A Németh A Láng 《The American journal of forensic medicine and pathology》1987,8(2):131-134
Fifty-six cases of paraquat poisoning were examined during the 8 years 1977-1984. The ratio of cases of accidental to intentional ingestion of the poison was 1:1; 23.2% of the total (13/56) survived several months or years. In 1983, 11 subjects accidentally drank 10-30 ml of gramoxone; eight of 11 died in 2 weeks. Toxicological investigations demonstrated rapid elimination of poison from the blood, as well as prolonged fixation of paraquat in the lung, kidney, liver, and spleen tissues. Histological examinations showed multiorgan failure from renal tubular necrosis and pulmonary hemorrhage with alveolar epithelial injury. Pulmonary proliferative changes were present in only two cases who survived 7 and 10 days and in which artificial ventilation was utilized. 相似文献

This article presents empirical findings regarding the relationship between decentralisation of provision of water supply and corruption in provision of services. The current policy advice from the international agencies of aiming for decentralisation as an end in itself is questioned. The conventional wisdom that decentralisation brings management closer to the service recipients and is therefore likely to reduce corruption is also disputed. Drawing on a large database from two large Indian states of Madhya Pradesh and Chhattisgarh, the interaction between various actors is analysed. We find that the level of corruption in water supply agencies run by local governments is higher than that in the agencies run by the regional government.
