The Psychological Influences of Threat on B2C E-commerce Adoption: An Extended Study and Explanatory Framework

In order to better understand how internet users actually decide to conduct business transactions or related activities in a B2C e-commerce environment, this article adds a new lens of study by investigating the roles of Threat Appraisal (TA) and Perceived Coping Appraisal (PCA) from the end user's perspective. Based on established academic theories and relevant industrial practices, it is suggested that TA and PCA are critical behavioral components influencing the user's intentions to participate in online transactions. These functions serve as important inputs to formalizing our understanding of how services offered by e-commerce websites are utilized.

随着我国污水处理厂的大量建成并投入运行,城市污水排放量不断增长,污水处理产生的污泥也不断增加。如果未经一定处理和处置的污泥直接进入环境,将会给环境造成二次污染,容易对生态环境和人类活动构成严重威胁。因此,如何合理地处理、处置污泥,已成为城镇污水处理厂和相关部门必须重视的问题。介绍了污泥的多种处置技术,并分析了不同处置技术的优缺点,指出土地利用在我国具有广阔的前景。     

The decline and fall of an industry

Abstract

Economic history abounds in research concerned with the growth of flourishing trades and with the factors causing their rise or prosperity. Declining trades and dying occupations have not received the same attention. Trades which are declining are, however, just as important as those which are prospering for the understanding of the processes of economic development.     

Inter-industry Technology Spillover Effects in China： Evidence from 35 Industrial Sectors

The present paper calculates 35 industrial sectors’ similarity matrices for the period of 1997-2008 using China’s input-output tables for 1997,2002 and 2007,and uses these to measure inter-industry technology spillover to analyze the spillover effects on industrial sectors’ labor productivity.The empirical analysis shows that inter-industry technology spillover has a significant positive effect on the labor productivity of each industry.The elasticity of productivity effects of inter-industry technology spillover is not only larger than that of direct R&D input,but also increases over time.We group the industries into four major categories and find that the inter-industry technology spillover effect within the categories is,on average,greater than that between the four categories,indicating that technology spillover occurs more easily between similar industries.This research shows that the interindustry technology spillover effect in China has begun to increase,and the government should take advantage of this effect.

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。
