We propose a communication analogue to Allport's () Contact Hypothesis called the Parasocial Contact Hypothesis (PCH). If people process mass-mediated parasocial interaction in a manner similar to interpersonal interaction, then the socially beneficial functions of intergroup contact may result from parasocial contact. We describe and test the PCH with respect to majority group members' level of prejudice in three studies, two involving parasocial contact with gay men (Six Feet Under and Queer Eye for the Straight Guy) and one involving parasocial contact with comedian and male transvestite Eddie Izzard. In all three studies, parasocial contact was associated with lower levels of prejudice. Moreover, tests of the underlying mechanisms of PCH were generally supported, suggesting that parasocial contact facilitates positive parasocial responses and changes in beliefs about the attributes of minority group categories. 相似文献

从契约伦理的视域看“以德治国” 总被引:2,自引:0,他引:2
本从契约伦理的角度论述了古今“德治”之划界以及在现代民制度下实现“以德治国”的问题。孔子从“性本善”的人性论假定出发,以德治、民本和礼治三统一建构了传统中国社会道德理想主义的基本理论框架,但孔子德治思想的存在背景是私民社会,现时代德治思想的指出背景则公民社会。私民社会是个无契约的社会,公民社会则是个契约社会,只有在契约伦理的视域中才能正确理解以德治国的科学内涵和重要意义。江泽民同志提出的依法治国和以德治国相结合的思想是对古今中外法制和道德自律思想的高度概括和科学总结,它根植于中外优秀思想而有所超越。 相似文献

Because of the different ways in which contact materials work, the basic requirements for silver metal oxide contact materials are different. They are anti-welded and anti-erosion when closed, anti-erosion when broken, and arc easily moved and have smaller contact resistance. In this paper, La2O3 is used as a stable oxide in contact material to replace CdO. A new type of Ag/SnO2-La2O3-Bi2O3 contact material is first obtained through using powder metallurgical method. Then electrical contact material parameter tester is used to test the electrical contact performance of the contact material. Through experiments, the arcing voltage and current curves, arcing energy curves, fusion power curves while broken and contact resistance while closed were obtained. Analysis of the results showed that the addition of La2O3 makes the contact material have the following advantages: smaller electrical wear, smaller arc energy, smaller contact resistance and arc is more easily extinguished. 相似文献

The emission and contact drying kinetics of the paper mill sludge (PMS) were studied through experiments carried out in a paddle dryer. To get a better understanding of its drying mechanism, a penetration model developed by Tsotsas and Schlünder (1986) was used to simulate the drying kinetics of the PMS. The result indicated that this kinetics could be divided into three phases: pasty, lumpy and granular phases, and could be successfully simulated by the penetration model as the related sludge parameters were integrated into the model. The emission rate curves of the volatile compounds (VCs) were interrelated to the drying rate curve of the PMS, especially for volatile fatty acids (VFAs) and ammonia in this study. 相似文献
