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

After two years of fighting in World War II, the US and Japan agreed on a second exchange of interned nationals. Neutral territory in Goa, Portuguese India, was chosen in October 1943, The US Consulate in Bombay directed the entire complicated operation. Two ships, each carrying approximately 1,500 refugees, all of whom required nationality checks, stateroom assignments, money settlements, sick passengers had to be transferred, and many other services had to be performed. As all were still enemies, they had to be kept separated throughout the operation. Remarkably, the acutal physical excahnge was completed in only three hours, on Tuesday, 19 October. 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
