Telecommunications Infrastructure (telecommunication + infrastructure)
Selected AbstractsDisaster management and mitigation: the telecommunications infrastructureDISASTERS, Issue 1 2009Frédéric Patricelli Among the most typical consequences of disasters is the near or complete collapse of terrestrial telecommunications infrastructures (especially the distribution network,the ,last mile') and their concomitant unavailability to the rescuers and the higher echelons of mitigation teams. Even when such damage does not take place, the communications overload/congestion resulting from significantly elevated traffic generated by affected residents can be highly disturbing. The paper proposes innovative remedies to the telecommunications difficulties in disaster struck regions. The offered solutions are network-centric operations-cap able, and can be employed in management of disasters of any magnitude (local to national or international). Their implementation provide ground rescue teams (such as law enforcement, firemen, healthcare personnel, civilian authorities) with tactical connectivity among themselves, and, through the Next Generation Network backbone, ensure the essential bidirectional free flow of information and distribution of Actionable Knowledge among ground units, command/control centres, and civilian and military agencies participating in the rescue effort. [source] Diffusion, Use and Impact of the Internet in Hong Kong: A Chain Process ModelJOURNAL OF COMPUTER-MEDIATED COMMUNICATION, Issue 2 2002Jonathan J. H. Zhu Hong Kong appears to be a dream venue for the Internet as a mass medium: There are a well-developed telecommunications infrastructure, a population with both financial resources and bilingual (Chinese and English) abilities, and a legal environment in which there is virtually no government regulation of content. However, recent experience with the slow adoption of other new media in Hong Kong, including cable TV and interactive TV, has sounded a cautionary note about the potential use and impact of the Internet in this technologically sophisticated city. Based on a telephone survey of 1,000 adult residents, this paper examines the adoption, use, and social impact of the Internet in Hong Kong using a chain process model that was initially developed by Dutton, Rogers, and Jun (1987) for research on home computing. The results show that Internet adoption is affected by a full range of factors, including one's personal characteristics, socioeconomic status, socio-cultural settings, and perceived compatibility of the Internet. On the other hand, Internet use is primarily affected by socioeconomic status and perceived compatibility. The study also found that both adoption and use of the Internet have observable impact on leisure activities and concerns for privacy and other Internet-related negative consequences. However, these effects are not overarching but rather confined to specific attitudes and behavior. [source] Multiple geographies of the Arab InternetAREA, Issue 1 2007Barney Warf The Arab world plays a relatively minor role in the rapidly changing geographies of global cyberspace. This paper explores the multiple geographies of the Arab Internet. First, it addresses Internet penetration rates, which averaged 7.8 per cent in 2006, although these varied widely among and within the region's countries. Between 2000 and 2006, the number of users jumped by 830 per cent, indicating these geographies are in rapid flux. It then examines the telecommunications infrastructure of the Middle East and North Africa, including fixed and mobile telephone networks and Internet cafes. Third, it turns to the reasons why the Internet has experienced relatively late adoption among Arab countries, including the dominance of the Latin alphabet, high access costs reflecting state-owned telecommunications monopolies, low Arab literacy rates, and restrictive gender relations that keep the proportion of female users low. The paper pays special attention both to government censorship of the Arab Internet as well as resistance to such controls and attempts to utilize the Internet counter-hegemonically. Finally, it explores the impacts of the Internet on some Arab societies, including the opening of discursive communities of politics, the Palestinian,Israeli conflict, Iraq and electronic commerce. [source] Factors influencing rural health care professionals' access to continuing professional educationAUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 2 2006Vernon R. Curran Abstract Objectives:,The purposes of this study were to explore the perceived barriers and challenges to continuing professional education (CPE) access for Canadian health care professionals and to identify best practices for improving access to CPE. Design:,Key informant interviews and Web-based online surveys were conducted. Participants:,Key informant interviews were conducted with national CPE accreditation bodies and health professional associations. An online survey was distributed to health professional education programs, as well as provincial professional associations, licensing and professional regulatory bodies. Main outcome measures:,The perceived barriers and challenges to CPE access for Canadian health care professionals and best practices for improving access to CPE. Results and conclusions:,Geographic isolation and poor technological and telecommunications infrastructure were identified as key barriers to CPE delivery and access. Financial factors, such as funding to support travel or cost of attendance, were also identified as major challenges. Tele-education programming was identified as a best practice approach to improve CPE access, as were regional CPE activities and self-directed learning programs. Employer-sponsored initiatives, including staff coverage or locum support, remuneration for time off and paid travel expenses for CPE participation were also identified as best practice approaches.

[source] Computer adoption and returns in transitionTHE ECONOMICS OF TRANSITION, Issue 1 2007Yemisi Kuku O; P2; J31 Abstract Across nine transition economies, it is the young, educated, English-speaking workers with the best access to local telecommunications infrastructures who work with computers. These workers earn about 25 percent more than do workers of comparable observable skills who do not use computers. Controlling for likely simultaneity between computer use at work and labour market earnings makes the apparent returns to computer use disappear. These results are corroborated using Russian longitudinal data on earnings and computer use on the job. High costs of computer use in transition economies suppress wages that firms can pay to their workers who use computers. [source] | ||||||||||
