基于潜伏期的网络蠕虫传播模型及其仿真分析

随着Internet的迅速发展，网络蠕虫已严重威胁着网络信息安全。现有的网络蠕虫传播模型仅仅考虑了网络蠕虫传播的初始阶段和达到稳定状态时的网络特性．不能刻画网络蠕虫快速传播阶段的网络特性。文章运用系统动力学的理论和方法．建立一种基于潜伏期的网络蠕虫传播模型，能够从定性和定量两方面分析和预测网络蠕虫传播趋势。模拟结果表明网络蠕虫潜伏期与免疫措施强度是影响网络蠕虫传播过程的重要因素。     

A split and swaying approach to building information society: The case of Internet cafes in China

This paper examines China’s approach to building an information society by using Internet cafes as a point of study. The central theme of this research is to explore the unique socio-political role of Internet cafes in China’s informatization efforts, the impact of the Internet and Internet cafes on the country’s democratization, and the authorities’ dilemma between promoting informatization and resisting democratization. Four related issues are discussed: (1) the swift development of Internet cafes; (2) the unique socio-political importance of Internet cafes in China; (3) the government’s split policy on the Internet and Internet cafes; and (4) the conflict between the public’s concern and the authorities’ concern with the impact of the Internet and Internet cafes. This study primarily relies on first hand data and research materials obtained through field research in China, including archive research of government documents, survey results, and interviews of relevant government officials, Internet cafe owners, communication scholars, and Internet and Internet cafe users.

Internet telephony: services, technical challenges, and products

The rapid proliferation of the Internet has given rise to a strong interest in carrying telephony over the Internet. Because the Internet supports data communications, a range of other services can be bundled together with Internet telephony. The Internet, however, was designed for non-real-time data communications, and hence it poses several technical challenges that must be overcome before the Internet can be successfully used for carrying telephone services. This article discusses new services we can expect from Internet telephony, the technical challenges and solutions, and the emerging products that promise to support Internet telephony

The multimedia fax-MIME gateway

New standards may help bridge the rapidly growing communities of the Internet and facsimile machine users. One of these is the Internet standard proposed in July 1992 which provides enhanced capabilities for e-mail. This new standard, Multipurpose Internet Mail Extensions (MIME), lets users exchange multiple-media mail messages over the Internet. The fax-MIME gateway takes advantage of these developments to offer fax services to Internet users and Internet services to multimedia fax users     

Internet facsimile as an Internet office appliance

The Internet's emergence as a worldwide digital infrastructure has dramatically encouraged a market for communications-oriented appliances, such as mobile phones, personal assistants, network-enabled games, interactive television, Internet telephony, and Internet facsimile. The marketplace is developing rapidly, along with specialized Internet-based “linking” services to connect these devices. Generally two different technical approaches are being explored for these services. One uses classic Internet technology, such as e-mail or the World Wide Web; the other incorporates unique standards, often derived from earlier non-Internet specifications. This article explores efforts to create Internet facsimile appliances, contrasting them with devices for Internet telephony. Efforts at Internet facsimile have produced two different sets of standards. Store-and-forward Internet facsimile is specialized as a profile of classic Internet mail. Real-time Internet facsimile uses a specialized protocol     

New Internet Trends and Technologies and Their Impacts on Telecom Industry

With never-ending changes and improvements and an increasing industrial scale of the Internet, the emerging new application trends, such as social networking, network video, intelligent search and mobile Internet, and new Internet technologies, such as Mashup, artificial intelligence, grid computing and open platform, are significantly influencing the Internet industrial structure. Moreover, the rapid development of the Internet and the convergence of the Internet and telecom networks, especially the development of mobile Internet, are giving the telecom industry a shock. This shock will certainly change the structure of the telecom industry, gradually break the monopoly status of telecom operators, shift the telecom emphasis to services and contents, and enhance the importance of terminal vendors in the industrial chain.

Understanding the impacts of Internet use on senior Citizens’ social participation in China: Evidence from longitudinal panel data

Scholars have appealed to build a digitally inclusive society to include senior citizens. However, conclusions on the impacts of Internet use on senior citizens’ social participation are divided. In order to address the above issue, this study addresses two questions: 1) how Internet use is related to senior citizens’ social participation; and 2) what the specific impacts of Internet use are on different subgroups’ social participation. We aim to understand the specific impacts of Internet use on senior citizens’ social participation meanwhile explore the reasons causing the abovementioned inconsistence in prior studies. We ran different panel regression models to address these questions based on a dataset drawn from the China Health and Retirement Longitudinal Study. Our empirical results indicate that seniors who are Internet users have higher social participation than those who do not use the Internet even after controlling out other influencing factors; however, frequent Internet use leads to less social participation among senior citizens. For senior citizens with higher cognitive functioning, both using Internet or not and the frequency of Internet use lead to more social participation. Both using Internet or not and the frequency of Internet use cause senior citizens with pensions to engage in fewer social activities. For female senior citizens, frequent Internet use leads to lower social participation. These findings suggest that government and communities should improve digital infrastructures and offer senior citizens more opportunities to access the Internet; meanwhile, local communities, social workers, and family members should direct senior citizens to use the Internet in a reasonable manner.
