In order to obtain evidence of the effects of demographic parameters and measurement techniques on personal space, several different assessments were used to determine the impact of subject age, race, and sex on interpersonal distancing. Thirteen different variables representing stimulation, paper-and-pencil, and behavioral techniques indicated that as age increased, personal space requirements decreased, particularly for whites. Blacks as compared to whites required less space at age 7, and mixed-sex dyads tended to require more space than same-sex dyads. The results thus indicate that while some previous findings appear to be measurement method specific, others show intermethod consistency.  相似文献

Prior to his 1922 emigration to Europe and thence to the United States, Pitirim Alexandrovich Sorokin had an exceptional intellectual and political career in Russia and the Soviet Union (Sorokin 1924, 1963a; Johnston 1995; Krotov 2005). Indeed, he was among the early founders of the science of sociology in his native land, where, according to a relatively recent bibliography (Sorokin 2000), he produced 162 Russian-language publications between the ages of 21 and 33. This listing includes not only book reviews and journal articles, but also substantial monographs and a two-volume theoretical treatise. While still a relatively young man, Sorokin had thus gained widespread recognition as a scholar of the first rank. He was also the initial chairperson (from 1919 to 1922) of a fledgling department of sociology at the University of Petrograd (St. Petersburg), an elected member of the national Constituent Assembly and an appointed staff member of the 1917 Provisional Government, the first democratic regime in Russia. This much would have sufficed for an entry in a sociological encyclopedia, and Sorokin’s political career has few parallels in the history of the field, other than the involvement of Emile Durkheim in French educational policy and the participation of Max Weber in creating the Weimar Republic in Germany. Nevertheless sociologists in the United States and most western historians of the field have not yet appreciated the full influence of the formative period, especially from 1905 to 1922. Lacking familiarity with Russian culture of that era and knowing little about the larger Russian socio-historical milieu, its intellectual discourse and collective memory, they have not been able to comprehend Sorokin’s outlook, behavior and professional output in the United States in relation to these earlier contextual factors. This is arguably a fundamental reason why many U.S. sociologists have tended to see Sorokin, especially since 1937, as a marginal figure and to regard his works largely as deviations from accepted social scientific practice. This paper will argue that a more adequate appreciation of Sorokin’s background and early adult life illumines both stylistic features of his works in America and also places into proper perspective several of his substantive foci that did not accord with contemporary “normal science” (Kuhn 1962). In short, despite his overall assimilation into American society and higher education, including his appointment at Harvard University and his election as president of the American Sociological Association, Sorokin should be understood in large measure as a life-long Russian intellectual. His was a Russian-born sensibility and consciousness—indeed a “Russian soul”—so deeply ingrained that it stamped his entire professional career in the United States, including his published researches, his popular sociology and his university teaching.  相似文献

American ecologists recently began to address the ecology of cities. Concurrently, higher education institutions have developed sustainability education programs and instituted sustainability policies and projects. This paper draws together these two disparate areas by examining the nitrogen (N) budget of the Twin Cities campus of the University of Minnesota. We addressed the question: what were the annual inputs, outputs and internal cycles of N on the University of Minnesota Twin Cities campus? We found that 508 Mg N yr-1 were brought into the campus and 494 Mg N yr-1 were emitted from the University of Minnesota campus. The largest N inputs were abiotic fixation (conversion of N2 to NOx by combustion) and food for humans and animals. The largest N output was NOx, followed by wastewater. Our results expand the understanding of the ecology of institutions within an urban area and provide an opportunity for improving urban ecology education and environmental policy at educational institutions.  相似文献

Why do some cities have higher or lower crime rates than others? In this study we attempt to answer this fundamental question by identifying the theoretically motivated structural covariates which differentiate U.S. cities with extreme high and low crime rates. We apply discriminant function analysis across comprehensive samples of all U.S. cities with populations of greater than 25 000 in the periods 1960, 1970, and 1980 and then posit four question: are empirical findings from regression-based studies of city crime rates replicated in discriminant studies with extreme rates? Are the covariates that predict high or low crime rates unique to specific time periods? Which covariates are better able to discriminate high or low rates for specific crimes? And are specific covariates distinguishable in crime rate changes across time periods? Among our general findings, it appears that those cities with extreme high (low) crime rates tend to be the largest (smallest), most (least) economically deprived, and most (least) socially disintegrated. Associations with these latter two characteristics appear to have grown stronger over the past three census periods. The theoretical importance of these and other findings uncovered here are discussed and interpreted through Wilson's (1987) notion of concentration effects and social isolation which may have transformed inner-city areas in recent years.  相似文献

This investigation compares school outcomes for students who differ in the extent to which they perceive their parents, friends, and teachers—each alone and in combination—as important sources of social support. Findings indicate that middle and high school students who perceive high supportiveness from all three sources of support, as opposed to none, one, or two, have better attendance; spend more hours studying; avoid problem behavior more; have higher school satisfaction, engagement, and self-efficacy; and obtain better grades. Positive school outcomes are promoted when teacher support is perceived in combination with perceived support from parents and friends. Implications of the results for human service providers are presented.  相似文献

加拿大采矿业注重培养技术工人   总被引:1,自引:0,他引:1  
采矿业面临着内外因素困扰,前进路上步履艰难,外部矿产品价格低迷,内部作业条件与环境恶劣.在这种严峻的情况下,矿业要千方百计克服矿产品开采与加工中的各种困难(挖掘深度加大、矿种品位降低、环保要求严格等等),除了提高生产效率、降低成本,最重要的是加快人才培养,改善人力资源管理.要达到上述目的,依靠传统办法,无法实现.所幸的是,进入21世纪后,以微电子技术为核心的科技进步为此提供了可靠的技术保证.这种需要与可能相结合就会诱导出一场变革,即技术革新,其中矿山自动化是这场变革中的主角.  相似文献

The study is conducted to determine families' rankings of characteristics they consider most important when selecting a nursing home. Friedman's two-way analysis of variance is used to test for differences in the rankings. In response to a mailed survey, 231 families rank the characteristics in the following order: quality of care, appearance, atmosphere, location, reputation, building safety, quality of food, cost, and activities. Relationships are also found between the rankings and the demographic characteristics: gender, marital status, education, income, number of homes available, patient/respondent relationship, and distance respondent lived from the chosen home.  相似文献
