“…Between 1999 and 2002, China invested 106 million landlines, attracted 163 million new cell phone subscribers and 36 million new cable television subscribers (WEF, 2004;Raven et al, 2007) to promote e-business. According to Economist (2005), China is adding four million mobile subscribers a month and has the world's largest broadband Internet market (Qi et al, 2006;Yan, 2008). Clearly, China is building an infrastructure to sustain future growth in e-business technology and to support the needs of global supply chain.…”

This paper explores relational benefits from Chinese customer's behavioural perspective, which is a valuable addition to the existing literature that focuses on the western cultural background. The findings of this research show that the relational benefits exist in the online shopping context. In addition to confidence benefit, special treatment benefit and social benefit that have been recognized in traditional services, a new benefit scale, honour benefit, is identified in this study. Empirical data from over 500 online consumers suggest that the relational benefits are becoming more and more important and can possibly turn into the sources of the new competitive advantage for the enterprise in the e-business environment.

“…This is especially important in the context of e‐business applications. In the light of the rapid growth of e‐business, many enterprise systems have to provide more services to meet the increasing demand of e‐commerce as well as paying more close attention to network security (Behesti et al ., ; Li et al ., ; Yan, ).…”

Modern Internet routers have to handle a large number of packet classification rules, which requires classification schemes to be scalable both in time and space. In this paper, we present a scalable packet classification algorithm that is developed by combining two new concepts to the well-known bit vector (BV) scheme. We propose a range search method based on a cache-aware tree (CATree) which makes full use of processor's cache line to reduce the number of dynamic random access memory (DRAM) accesses. Theoretically, the number of DRAM accesses of CATree is about log(m þ 1) times lower than that of the widely used binary search algorithm, where m is the number of keys in a single cache line. Based on our computational results on a set of 1024 keys, the CATree algorithm is 36% faster than binary search algorithm and the performance is better when applied to a larger set of keys. In addition, we develop a rule re-arrangement algorithm to reduce the bitmap space of BV. With this rearrangement, the rules for the same action may be assigned an identical priority. This reduces the number of priorities as well as the memory space of the bitmap. Furthermore, this also reduces the number of memory accesses and hence, increases the CPU cache utilization. With CATree and rule re-arrangement, the cache-aware bit vector with rule re-arrangement algorithm achieves better performance in comparison with the regular BV scheme, both in space and time. In our experiments, the proposed algorithm reduces the bitmap memory space of a practical set of firewall rules by two orders of magnitude and is 91% faster than the regular BV.

“…Discussion from Systems Perspectives 1. Information security is the bottleneck for development and the key is achieving a unified platform Electronic administration has a high requirement for information security given its importance to the interest of the nation or related departments (Yan, 2008). As the Internet is an open network, computer viruses, hackers, information espionage and potential escalation of internet terrorism after the 9/11 attacks will all pose an appalling threat to the electronic government.…”

Government informatization: a case study

2009

View full text Add to dashboard Cite

Government informatization, as a new feature of public administration, has gained intense attention in China. After years of development, there have been some achievements but at the same time, it is still rife with problems. This paper gives a comprehensive analysis on the background of government informatization in China, expounds on the trend of the e-government in China by using the case of Shenzhen, and introduces the development of e-government in some other cities. On top of that, we predict the trend for government informatization and propose that e-government will be the future direction for China's public administration.
