Search boundaries: human flesh search,privacy law,and internet regulation in China     

Dong Han 《亚洲交流杂志》2018,28(4):434-447

This research examines privacy law and Human Flesh Search (HFS) on the Chinese Internet. HFS is spontaneous, widely participated search and publication of targeted individuals’ personal information on the Internet. This research sees HFS as an important form of non-institutional information gathering and publication, and argues that the regulation of HFS is not only about privacy but also line-drawing for information collection and dissemination in the digital setting. Therefore, legal instruments and court cases in relation to HFS and online privacy must be assessed as important components of the Chinese state’s Internet regulatory scheme. This research finds that the paired concepts of ‘flexibility and populism,’ key features of legal reform and development in contemporary China, are highly relevant to analyze the growth of digital privacy laws in China. The political-legal authorities’ experimentation and innovation in the development of the law shed important light on how China’s Internet governance adapts to changing circumstances and strives to keep pace with profound social transformations in new technological environments.  相似文献

The Effect of Web Search Result Display on Users’ Perceptual Experience and Information Seeking Performance     

Hosam Al-Samarraie  Ahmed Isam Al-Hatem 《The Reference Librarian》2018,59(1):10-18

ABSTRACT

Adding multiple sources of information in the display of Web search results may negatively affect users’ perceptual experience and information-seeking behavior. This claim was established by investigating the impact of different Web search compositions on users’ ability to extract specific information. In this article, we assumed that the quantity and order of different compositions (areas) in the Web search results page may contribute to individual’s ability to find information relevant to their search queries. An eye-tracking device was used to observe and compare the perceptual behavior of 14 users in an information-seeking task. The results showed that the use of different compositions in the display of Web results page significantly influenced users’ perceptual experience by reducing their attention to the organic results area. The quantity of these compositions was found to greatly increase the cognitive load of users when attempting to retrieve information from the organic area, which negatively affects their information-seeking performance. Our finding provides a rationale for further studies to consider the impact of quantity and order of Web page compositions on individuals’ perceptual attention and cognitive load in information-seeking task settings.  相似文献
