This article provides a critical comparative analysis of mobile versus personal computer (PC)-based forms of Internet access. Drawing from an interdisciplinary body of literature, it illustrates a wide range of ways in which mobile Internet access offers lower levels of functionality and content availability; operates on less open and flexible platforms; and contributes to diminished levels of user engagement, content creation, and information seeking. At a time when a growing proportion of the online population is “mobile only,” these disparities have created what is termed here a mobile Internet underclass. The implications of this argument for digital divide policymaking and, more broadly, for the evolutionary trajectory of the Internet and the dynamics of Internet usage are discussed. 相似文献

Our objectives for this article are twofold: first, to examine the convergence of nations with regard to ICT access; and second, to see whether countries in the same continental region (South and East Asia, West and Middle East Asia, Africa, Eastern Europe, Western Europe, North America, South America, and Oceania) or having same initial ICT access have coalesced into groups. We constructed an ICT access index using three indicators (mobile phone, Internet, and broadband use per 100 population) for a sample of 198 nations for the 16-year period from 2000 to 2015. Results show that digital divide has declined in relative terms, but not in absolute terms. The countries, starting at lower ICT levels, are not adopting ICT faster than the leaders. Continental region-wise analysis also shows that the catch-up is maximum for already developed countries, and minimum for countries in African and Oceania continental regions. 相似文献

The fourth generation mobile phone soon will be launched. Marketers are concerned about customer acceptance, and, in particular, about the main factors that determine whether customers will upgrade their mobile phones, which will affect the diffusion of 3G, 4G, and Worldwide Interoperability for Microwave Access phones. We integrated post- and pre-adoption theories, upgrading and value-based theory and chose 2G and 3G users to examine customers' plans to upgrade their current phones, and found that value assessments can affect mobile users' plans to upgrade to next-generation versions. When 2G mobile users were satisfied with their current model, they were not willing to upgrade to 3G mobile phones. They tend to upgrade by leapfrogging the next generation product as an indirect result of their positive satisfaction with their current model. These results suggest that 2G mobile users consider the 3G mobile phone to be a transitional product, and will wait for future options that are expected to perform better than those presently available. 相似文献

This exploratory online questionnaire-based study confirms the findings from earlier studies in the pre-smart phone era regarding consumers’ negative attitudes towards mobile marketing communications. This study shows that these attitudes persist despite increasing frequency of use and increased functionality of mobile phones in the smart phone era. Consumers perceive their mobile device to be for personal communication, and prefer to be able to exercise control over their interaction with organisations. Findings suggest that acceptance can be enhanced by permission marketing, trust-building, creating a sense of being in control, and useful and entertaining website content. Accordingly, pull technologies seem to hold particular promise for mobile marketing communications. This study, therefore, proceeds to explore use of and attitudes towards an important pull technology, QR codes. QR codes, two-dimensional bar codes, can be scanned to provide access to websites, information and applications. Despite their potential, uptake is low. Users in this study who had scanned a QR code had used them to access a variety of different content on different types of items and in different locations. The most frequently accessed type of content was information on a web site, the two most common locations for a scanned QR code were a newspaper or magazine advert, or outdoor advert or poster, and the two most common locations at which scanning was performed were in the street and at home. Ease of use, utility and incentives are drivers to continued use whilst lack of knowledge about how-to scan or of the benefits of QR codes may hinder adoption. Recommendations are offered for practice and for further research. 相似文献

The mobile Internet (MI) has been hyped as the next big thing by telecom operators, handset manufacturers, and content providers. However, recent studies indicate that the usage of Internet via mobile phones has remained quite flat. The authors inquire into this discrepancy by focusing on actual usage of the MI and the motivating factors behind its use. Based on focus-group interviews in Norway and Hungary, they argue that MI usage is interrelated with and is an extension of the personal computer (PC)–based Internet. The key motivation behind MI use is to attain information in situations in which the PC is out of reach. In effect, MI has not led to the development of new usages. The expectation that the development of new killer applications will lead to an explosion of new usage is therefore misguided. MI usage is and will perhaps continue to be a mere extension of PC-based Internet usage—and such use activities are the very nature of MI. 相似文献

As the rapid development of broadband Internet access services continues, particularly fiber to the home (FTTH) services, the digital divide between provincial and urban areas is becoming a big social issue in Japan. We classify the issue into two problems: access to high-speed Internet, and service utilization of high-speed Internet access. We focus on the latter problem by quantitatively and qualitatively investigating whether a digital divide problem exists based on Internet service utilization. Consequently, we discover that willingness to pay (WTP) for public services over FTTH is almost identical between provincial and urban areas. Furthermore, territorial digital broadcasting over FTTH accounts for a large part of WTP in provincial areas, while tele-working and tele-education are also important as public services over FTTH in urban areas. 相似文献

In Indonesia mobile technology has come at the end of 35 years of the Suharto regime, and in its aftermath an era of new openness. Not surprisingly mobile phones are by many Indonesians associated with the new freedoms of this post-1998 period, facilitating newly emergent youth cultures, a hip mobile lifestyle as well as experiments with novel sexual identities. In a country characterized by stark contrasts—between center and periphery, city and countryside, and the rich and the poor—this has at the same time resulted in an uneven spread of technology, and thus in the coexistence of very diverse cellular markets. Through deliberating the pros and cons of mobile technology, new possibilities the phone seems to offer, and the often creative solutions people find in gaining access to mobility, it is shown how Indonesians try coming to terms with the otherwise abstract notion of (post)modernity. 相似文献

Technological progress is often at the heart of improvements in quality of life. The development of personal computers (PCs) and the Internet are among the most important technological advances of the last century. PCs and the Internet have profoundly changed the way we access information, shop, view media, communicate, socialize, and spend our time. Despite the many benefits of computer and Internet use, certain population groups – especially low-educated and older consumers – have not yet fully adopted computer technology and the Internet in their daily lives. This paper estimates the effects of early-life education on computer and Internet use among older Italians. Using data on early-life educational attainment and computer and Internet use of older adults from the 2013 Survey of Health, Ageing and Retirement in Europe (SHARE), we exploit a historical increase in compulsory schooling in Italy as an instrumental variable for education to estimate the effects of early-life education on the adoption of PCs and on current use of the Internet. We find large and statistically significant effects of early-life education on later-life technology use among older persons who obtained additional education due to increased schooling requirements. In our benchmark estimations, one additional year of schooling resulted in an eight percentage point increase in the probability of having ever used a computer and in a 12 percentage point increase in the probability of reporting to have at least good computer skills. Individuals affected by the reform were also six percentage points more likely to have used the Internet in the last week. These findings are robust across different sample selection and model specification strategies. Our analysis also suggests that occupational choice and computer use at work are important channels through which education affects the adoption and use of computers and the Internet. Our findings thus highlight the likely importance of early-life education for later-life computer and the Internet use and perhaps technology adoption more broadly. 相似文献

Research consistently indicates that Latinos and African-Americans are less likely to own and use computers than either Caucasians or Asians. While conventional wisdom holds that high computer costs and lack of access are the primary reasons for this discrepancy, my ethnographic research with 100 low-income adults reveals three non-cost-related psychosocial obstacles that significantly undermine motivation for acquiring computer skills: “relevance,” “fear,” and “self-concept.” My research thus suggests that a more complex relationship exists between ethnicity, identity, and attitudes associated with computers than previously examined; this relationship may better explain why some people are choosing not to use computers at this time. My research also indicates that while community technology centers (CTCs) play an important role in helping adults overcome their resistances and achieve computer literacy, they are presently an underutilized resource—less than 5% of San Diegans use them to meet their computing needs. Hence, my research also questions why more residents do not avail themselves of these community resources. I conclude that efforts to increase computer literacy in underserved communities must go beyond physical access and connectivity and consider the role of cultural factors. 相似文献

Digital inclusion research has focused overwhelmingly on access to information. But access to information by itself is of limited value unless the intended beneficiary has the capacity to use it. It is the use of information that delivers the benefits. However, in information and communication technologies for development literature, there is little empirical work on the process by which use of information delivers benefits. This study fills the gap by studying information use by poor female mobile phone users in rural India. It identifies six stages in the information use process and models them. 相似文献
