In 1948–49 the Sociology Office of the University of Oslo, under the guidance of Prof. Paul Lazarsfeld of Columbia University, initiated a series of studies on the Norwegian economic planning system. Part of this Planning Project was a national election survey in the fall of 1949, on a modified probability sample of 2600 people. The results show the paramount influence of economic class on voting, interpreting class as a combination of employer/employee relationship, property ownership, prestige-status, and income. Indicators of the homogeneity of class environment also played a role. Given the occupational structure of Norway, the Labor party had to win over part of the non-working-class population to obtain control of the government. They did this by winning about 1/3 of the white-collar vote, and about 1/4 of the farmers and fishermen. The policies of economic stabilization - control of inflation through price controls, wage controls, food subsidies, and rationing, and maintenance of full employment under conditions of "suppressed inflation" - were crucial to winning over these white-collar and farm voters. 相似文献

We measured stable hydrogen isotope ratios in the primary feathers of two subspecies of goldfinches, confiscated by the Police and the Royal Society for the Prevention of Cruelty to Animals (RSPCA) on suspicion that they had been illegally taken from the wild. We found significant differences in the delta2H values of the two subspecies indicating that they were sourced from different geographical regions. Our results correlated with isotopic precipitation maps and with the known distribution of the two subspecies of goldfinch. We believe that this technique could be used by law enforcement agencies to determine the origin of birds in cases where the species or subspecies involved are geographically distinct. 相似文献

Identification of fentanyl derivatives 总被引:1,自引:0,他引:1
An interpretative approach to the identification of fentanyl homologs and analogs is presented. The techniques employed are liquid/liquid extractions; capillary gas chromatography; and infrared, mass, and nuclear magnetic resonance spectral characterization. Spectral data are presented for eight fentanyl derivatives of clandestine origin. 相似文献

Roy B. Allen 《Journal of Quantitative Criminology》1986,2(2):139-156
Criminologists seldom have attempted to measure the severity of physical injury to victims of aggravated assault and homicide, even though it is significant to many of their research efforts. Previous attempts have been neither medically accurate nor medically acceptable. In this paper the author discusses the shortcomings of these efforts and introduces an alternative method which is valid, reliable, and medically acceptable. In addition, the author discusses its applicability to research the impact of medical intervention on violent criminal assault, on factors which contribute to the severity of assaultive injury and the lethal outcome of violent assault, on specific questions regarding the patterns of offending and victimization, and on the administration of criminal justice. 相似文献
