声光双控节能灯电路设计

为解决工厂长明灯现象,设计了一种声光双控节能电路供楼道照明灯用,其功能:夜间有人上下楼时,照明灯自动点亮,灯亮后延时2～3分钟,会自动熄灭;白天照明灯受人走动的控制,灯不会点亮。整个电路由电源电路,放大电路,处理电路(声控电路、光控电路)及延时电路等部分组成。     

Social Interaction Effects in Disability Pension Participation: Evidence from Plant Downsizing*

We estimate the magnitude of social interaction effects in disability pension participation among older workers in Norway. The problem of omitted variable bias is addressed using the exposure of an individual's neighbors to plant‐downsizing events as an instrument for the disability entry rate among the individual's previously employed neighbors. Our instrumental variable (IV) estimates suggest that an increase of one percentage point in the participation rate of previously employed neighbors increased the subsequent four‐year entry rate of older workers by about 0.4 percentage points. Numerous robustness and specification tests appear to support the validity of the identifying assumption in our IV strategy.     

论科技权力与政治权力互动关系

大科学时代,科技权力与政治权力日益成为对人类社会发展影响深刻和显著的两大权力系统。一方面,科技权力不仅作为生产力的手段推动着经济社会的发展,还推动着政治权力的变革和完善。另一方面,政治权力通过行政的、法律的等手段不同程度地影响和制约着科技权力的发展速度,规定和引导着科技权力的发展方向。认清科技权力和政治权力的二元互动关系,无论对于我国科技权力的发展还是政治权力的进步都具有一定的意义。

课堂师生互动 提高课堂效率

在当今这个知识腾飞的年代,掌握知识的多少已经不是教学的最终目标,如何学会知识这才是最重要的。新课改理念下的师生互动就是克服传统课堂中的单一枯燥的教学行为,打破课堂的沉闷,让学生在一种愉悦亢奋的状态中主动学习、积极思考。基础教育的任务不仅仅是传授知识,更重要的是让学生学会学习,培养可持续的学习动机和终身学习的愿望和能力。本文通过对师生互动的前提、师生互动的保证、师生互动的基础、师生互动的内在动力、师生互动的修养、师生互动的提问等几个方面来阐述如何落实师生互动,提高课堂效率,使师生互动的价值在数学课中真正显现出来。     

The Role of Individualism/Collectivism in Critical Classroom Encounters

Abstract

Internationalization raises the issue of whether, and to what extent, the inherent culture of a country may have particular influence on the nature of service interactions, and on education (i.e., student-professor interactions) specifically. Thus the service encounter in the classroom becomes a subject of increasing importance and interest with respect to satisfactory and unsatisfactory outcomes, and also with respect to related behavioral outcomes such as word-of-mouth and repatronage. This paper investigates these issues in classrooms of higher education by utilizing the Individualism-Collectivism dimension of culture in four different samples: China, New Zealand, Poland, and the United States. Differences are identified with respect to the types of critical incidents reported, nature of the outcome, and behavioral responses to those encounters.     

From Selling to Relationship Marketing at International Trade Fairs

Abstract

The role of international trade fairs in establishing and developing buyer-seller relations has been overlooked by most marketing scholars. Based on a survey of sellers at international trade fairs, relationship marketing at trade fairs is analyzed. Using an interaction approach, some propositions are developed. The article suggests that international trade fairs play a significant role in reducing uncertainty and distance for industrial marketers and in demonstrating commitment to the buyer-seller relationship development process. The implications for practitioners, as well as for future research, are discussed.     

Innocents Abroad: Attitude Change toward Hosts

The purpose of this study was to examine the role of social distance, prior expectations, and trip experience on post-trip attitudes in multiple destinations. This study is based on surveys conducted with two groups of students: 1) a group participating in a summer study abroad program to the South Pacific or to Europe, and 2) a control group. The results show that attitude changes were positive towards Europeans, negative towards Australians, and mixed towards Fijians. This study supports the expectation value theory, but contradicts the cultural distance theory of attitude change. Further, the results show that experience with non-tourism related services played an important role toward attitude change.
