The Internet has become an ordinary and widely accepted alternative social environment—known as cyberspace—in which many people take part in numerous activities. For the hearing-impaired, cyberspace provides extra benefits for two basic reasons: means of communication, which is primarily based on visual (text and images) and not auditory channels, and the convenient possibility of concealing their handicap from other users, thus gaining more security and a sense of equality. The purpose of the current study was to examine characteristics, intensity, and types of use of the Internet by hearing-impaired adolescents compared to an equivalent group of normal-hearing participants, with gender and adolescence stage (age 12–15, or 16–19) as additional independent variables. In addition, the intensity of using the Internet as a possible moderator of deaf participants’ well-being was examined by comparing measures of loneliness and self-esteem between low- and high-intensive hearing-impaired users on the one hand, and hearing participants, on the other. Questionnaires were administered to 114 hearing-impaired and 100 hearing participants, matched for intelligence and socio-economic status. Main results showed that for both genders and for the two adolescence stages, hearing-impaired participants were motivated to use, and actually did use, the Internet more intensively than their hearing counterparts. Furthermore, the hearing-impaired used the Internet more than did hearing participants for both personal and group communication. Hearing and intensively Internet-using deaf participants were similar in level of well-being, both higher than the well-being of less-intensively Internet-using deaf participants. The Internet may thus be viewed as an empowering agent for the hearing-impaired. 相似文献

In this case study, wiki technology was applied to the development of an introductory academic textbook on information systems. While the development, production and distribution of traditional textbooks are influenced by commercial interests, the wikitextbook was developed collaboratively by faculty and by students, and was made available online free of charge. After about two years of activity, the wikitextbook accumulated 564 sub-chapters, co-authored by undergraduate and graduate students in more than 20 classes offered by seven academic departments across three Israeli universities. We discuss the potential of wikitextbooks as vehicles of empowerment to students, teachers, and the discipline. This type of collaborative online technology intimates an influence on the status-quo in academic education in favor of less empowered stakeholders. However, caution is advised in drawing premature conclusions from results reported here. The implementation of wikitextbook should be augmented by a careful study of cultural, societal, behavioral and pedagogic variables. 相似文献

This paper reports a study investigating the relationship between Internet identification, Internet anxiety and Internet use. The participants were 446 students (319 females and 127 males) from two universities in the UK and one university in Australia. Measures of Internet identification and Internet anxiety were developed. The majority of participants were NOT anxious about using the Internet, although there were approximately 8% who showed evidence of Internet anxiety. There was a significant and negative relationship between Internet anxiety and Internet use. Those who were more anxious about using the Internet used the Internet less, although the magnitude of effect was small. There was a positive and significant relationship between Internet use and Internet identification. Those who scored high on the measure of Internet identification used the Internet more than those who did not. There was also a significant and negative relationship between Internet anxiety and Internet identification. Finally, males had a significantly higher Internet identification score than females. Implications of these findings are discussed. 相似文献

A preliminary study of the level of Internet use by Chinese firms was carried out. Data were collected by a questionnaire survey of a convenience sample of Chinese managers. The major finding is that firm size plays a role only in influencing a firm’s decision regarding whether or not to have Internet access. Within the Internet-using sub-sample, firm size is not significantly related to the overall level of Internet use, or to the use of individual Internet features. In addition, the data reveal that there are a high proportion of Chinese businesses that have Internet access. Chinese Internet using firms use an average of three features, with e-mail and buying and selling online being the two most widely used features. The results are also compared to similar studies in other countries. The limitations of this study and future research are discussed. 相似文献

The information revolution is bringing people of different backgrounds from around the world into a global information superhighway. The Internet provides a global platform connecting thousands of networks around the world. There is a variety of information available on the Internet for the users. It has been considered as a forum for users to share worldwide information resources. The resources are so vast that many of us really cannot grasp or understand the Internet fully. It has become a ‘global information library’ which allows the users to participate in the group discussion, search for any information, start any discussion with others and so on. It can be considered as a hybrid environment of postal services, citizen's band radio, libraries and neighborhood community centers where we (‘we’ is mainly used in this paper in its generic form) can spend time with our friends (‘our’ is also mainly used generically). Internet users (Internauts) share jokes, gossip in on-line conferences and join special groups to keep abreast of their specific interests. The main objective of this tutorial is to discuss various services on the Internet, their implementations, various Internet tools, and interconnection to the Internet. Other important issues like the Internet addressing, domain name system, IP addressing, etc. are discussed in detail in order to understand some design concepts. A brief list of the different types of browsers for different platforms is given. A discussion on future of the Internet is given via different advances and tools defined to provide security, interconnectivity and other related issues. 相似文献

The aim of this paper is to review the gradually evolving body of the literature on Internet addiction. Two schools of thought have emerged: those authors who believe that Internet addiction merits classification as a new or emerging psychiatric disorder in its own right, and those who define certain individuals as having problematic Internet use in relation to specific online activities, such as gambling, email or pornography. Despite a total lack of methodologically sound research, the evidence appears to support the second perspective. It appears that individuals who are premorbidly vulnerable, especially with a history of impulse control and addictive disorders, are especially at risk of using the Internet in a problematic way. Aside from the personal and social implications of this finding, this behavior has important implications for the workplace and may be resulting in substantial loss of productivity in companies who are not implementing Internet governance policies. 相似文献

从互联网角度对物联网进行了深入浅出的分析。物联网是在计算机互联网的基础上,利用RFID、无线数据通信等技术,构造一个覆盖世界上万事万物的"Internet of things"。在这个网络中,物品(商品)能够彼此进行"交流",而无需人的过多干预。其实质就是综合利用各种技术,通过互联网实现物品(商品)的自动识别和信息的互联与共享的目的。不论是物联网的概念内涵,还是使用的相关的技术,物联网都没有脱离互联网,二者的基础是一致的。 相似文献

Next to available data about actual Internet use of young children at home, most research especially focuses on the threats and opportunities about active Internet usage. Limited empirical research focuses on the role and impact of parents in this context. In the present study, Internet parenting styles are defined and operationalized to study the impact on actual Internet usage of children at home. Two dimensions are distinguished in Internet parenting styles: parental control and parental warmth. Based on a survey, involving 533 parents from children in primary schools, this Internet usage was studied from the perspective of Internet parenting styles. Results point at high Internet access at home. As to the parenting styles, we observe a dominance of the authoritative parenting style (59.4%). The styles differ when controlling for parent gender, educational background and age. Parenting styles are also linked to level of parent Internet usage, Internet attitude and Internet experience. Parenting styles also significantly affect child Internet usage. The highest child usage level is perceived when parents adopt a permissive parenting style; the lowest level is observed when parents adopt an authoritarian Internet parenting style. The variables Internet parenting style, parent Internet behavior, and parent educational background significantly predict Internet usage of children at home (R2 = .44). Theoretical and practical implications are discussed and directions for future research. 相似文献

Regardless of the different theoretical positions held at present, we can probably agree that an abusive and problematic use of the Internet exists. We present an instrumental study whose objective is to develop a brief, valid, and reliable questionnaire to measure this abuse in epidemiological contexts. The Internet Abusive Use Questionnaire (IAUQ) consists of 12 items to respond to according to the Likert scale. A total of 908 respondents participated, 48% males, with ages ranging between 17 and 70 years. The IAUQ showed a single factor structure. This model presents a good adjustment, with CFI, GFI, and NFI fit index over .90. Internal consistency was found to be .90. The IAUQ showed direct correlations with the Internet abusive use self-assessment, anxiety and depression, and inverse correlations with quality of life. All correlations were significant (p < .001), which demonstrated convergent validity. Significant differences were also found in the IAUQ scores among groups with different age, cultural level, and other addictions, which evidenced discriminant validity. In conclusion, the obtained results demonstrate structural validity and adequate indices of convergent validity and discriminative capacity. These psychometric characteristics —combined with the fact that the IAUQ evaluates harmful use of Internet briefly and simply— fulfill our goal. 相似文献
