消费者网评使用习惯对网评效应的影响研究---网评奖励效果的中介和调节效应探索*

本文以网购旅游者为调查对象，分析其网评使用习惯及其在网评奖励效果作用下对网络评论效用发挥的影响。通过问卷调查和数据分析发现，网评使用习惯和网评奖励效果都对网评效应具有显著正向影响，但网评使用习惯的影响力大于网评奖励效果。同时，网评奖励效果对网评使用习惯与网评效应间的关系具有显著负向调节效应，它削弱了消费者网评使用习惯对网评效应的影响；但消费者的网评使用习惯不通过网站的网评奖励效果对网评效应发挥作用，网评奖励效果不具有中介作用。可见，在网评使用习惯、网评奖励效果和网评效应三者关系中，网评使用习惯是个独立的影响因素，它并不通过网评奖励效果发挥作用，并且由于网评奖励效果的加入，反而削弱了网评使用习惯对网评效应的影响。研究结论表明，对于网评奖励政策的效果，需要客观辩证地看待，不应一味夸大。

The Use of Telematics Devices to Improve Automobile Insurance Rates

Most automobile insurance databases contain a large number of policyholders with zero claims. This high frequency of zeros may reflect the fact that some insureds make little use of their vehicle, or that they do not wish to make a claim for small accidents in order to avoid an increase in their premium, but it might also be because of good driving. We analyze information on exposure to risk and driving habits using telematics data from a pay‐as‐you‐drive sample of insureds. We include distance traveled per year as part of an offset in a zero‐inflated Poisson model to predict the excess of zeros. We show the existence of a learning effect for large values of distance traveled, so that longer driving should result in higher premiums, but there should be a discount for drivers who accumulate longer distances over time due to the increased proportion of zero claims. We confirm that speed limit violations and driving in urban areas increase the expected number of accident claims. We discuss how telematics information can be used to design better insurance and to improve traffic safety.     

Information society and digital divide in South Africa: results of longitudinal surveys

Integration into the information society implies that information plays an increasingly important role in all sectors of society and holds distinct social and economic benefits. Discourses on the information society are, however, also associated with the digital divide and inequalities in access to and use of information and communication technologies (ICTs). Within sub-Saharan Africa, South Africa is often regarded as one of the most information-integrated societies due to widespread mobile phone ownership, among other things. However, while ICT access has been emphasized, research also points to the role of demographic, socio-economic and cultural factors such as ethnicity, income, education and gender. This article discusses the results of questionnaire surveys conducted by Afrobarometer among probability South African samples in 2008 and 2011. The results indicate that individual Internet use and mobile Internet access were lower than estimated in the literature. Furthermore, gender gaps, as well as considerable gaps between population groups and educational levels, were found in Internet and computer use, mobile ownership and access to mobile Internet and accessing news via the Internet. Conclusions regarding strategies for bridging the digital divide and integrating South Africa into the information society are discussed.
