This article examines whether the small number of Social Security beneficiaries living abroad enjoy a higher standard of living than they would with the same benefits if they lived in the United States. The article addresses this question using two methods. First, absolute comparisons of U.S. dollar purchasing power abroad are made using "purchasing power parities," a method recently developed to allow international comparisons of real standards of living. Second, the effects of changes in Social Security benefit levels, exchange rates, and rates of inflation on the relative value of benefits abroad are measured. Both methods show considerable instability in purchasing power of Social Security benefits in the 1970's. Although beneficiaries in 1970 generally could live better abroad than in the United States, this advantage eroded considerably during the 1970's, followed by some improvement in 1981-82. 相似文献

This article examines effects of the "open-elections" law passedby the Louisiana legislature in 1975. The law eliminated traditionalclosed party primaries, creating instead, an open-electionssystem that requires all candidates, regardless of party affiliation,to appear on the same ballot. By and large, the new system hasnot had a significant effect on party competition, party success,or voter turnout in Louisiana. 相似文献

A life-span developmental perspective suggests that variations in social context will lead to differences among individuals in their action orientations. An action orientation is defined by an individual's values, control beliefs, goal orientation, and decision-making perspective. To investigate differences in the action orientations of adolescents embedded in different contexts, 83 sophomore and senior high school students on either a vocational training or college-preparatory trajectory participated in the study. A discriminant function analysis of action orientations showed that the action orientations of vocational training and college-preparatory students differed: College-preparatory students had a career preparation action orientation and vocational students had an adult preparation action orientation; also, sophomores may have had a socializing orientation. The findings are discussed in terms of the developmental tasks facing students in different grades and on different life-course trajectories.

Narcotics "body packing" can be detected in abdominal X-rays by the ring shadow caused by air trapped in the packs. In a series of 82 cases admitted for abdominal X-ray in Helsinki, Finland, in 1982 through 1988, we encountered 9 (11.0%) true positives, 3 (3.6%) false positives, and 1 (1.2%) false negative. The false positives were due to the constipation often associated with the narcotics abuse. The false negative X-ray diagnosis was attributable to an inexperienced radiologist. False negatives may also be associated with packets containing marijuana, packs with few wrappings, aluminum-foil coated packs, and machine-packed narcotics. Searching for trapped air in radiographs, repeated X-raying by an experienced radiologist, use of computed tomography, or combined urinary drug screening may be applied to diminish false findings and to avoid unnecessary arrest for the purpose of fecal screening over several days. 相似文献
