Automated computer technologies utilizing e-mail or SMS text messaging reminders can help overcome adherence barriers to optimal glycemic control in patients with diabetes. Text messaging on cellular phones, in particular, has become a popular communications tool among adolescents and young adults. We have created an automated computer system that provides reminders to check blood sugars by e-mail or text messaging on a cellular phone. The reminder schedule is set on a password-protected web site by the user according to his or her preferences. Users can respond to the reminders with their blood sugars, which are time and date stamped and then stored in a database. Text parsing rules allow users to override the time and date and to attach a comment as well. The blood sugar log can later be viewed and edited on the web site. Positive feedback is provided for every blood sugar entered and users also have the option to have both general and diabetes facts sent to them daily at random times via e-mail or text messaging. A randomized, controlled trial comparing e-mail with text messaging is underway at the time of this writing to test the feasibility and utility of this system in patients with diabetes. Preliminary results from 10 users (mean age 18.9 [plus-minus] 2.0 years) indicate that the system appeals to a subset of the study population. Two of the ten subjects have been using the system consistently...

A system dynamics model is developed and run to study the adoption of fiber-to-the-home as a residential broadband technology. Communities that currently do not have broadband in the United States are modeled. This case is of particular interest to U.S. policymakers, but also relevant to other regions concerned with economic development in rural areas. The model is used to explore the effects of government policy on fiber-to-the-home deployment and on the telecommunications supply chain. The research finds that government policy relating to broadband deployment has been based on a weak understanding of the dynamics involved, resulting in trial and error policy making that has unintended consequences. The thesis shows that the current monitoring of broadband deployment by the Federal Communications Commission is inadequate to contribute to the formation of reasoned policy decisions. The model is used to explore the consequences that different regulatory scenarios have on fiber-to-the-home deployment. Among the policy choices considered are: resale of fiber-to-the-home lines to competitive providers; low cost government loans for commercial deployments; rapid deployment to all communities currently without service; and a ban on municipal deployments. The current Rural Utilities Service loan program is also included in the model and its effects are analyzed. The model is used to examine the consequences for the optoelectronics industry of different deployment scenarios. It shows that the interests of consumers...

How can concepts from literature and technology design combine to create new forms of storytelling on mobile devices? This paper examines the theory and practice of bringing literary techniques into mobile technology design. First I present a model of media technology evolution which is not progressive, but atemporal-grounded in the ongoing expressive challenges of the humanities. This theory forms the basis for what I call the exchange: temporary collaborations between creative writers and interaction designers which lead to new forms of fiction and communications technology. I promote close readings of literature as a starting point for the exchange, examining specific passages for mobile storytelling inspiration and innovative means of modeling users. I then look at nascent efforts in storytelling over mobile devices, focusing on museum tours, grassroots organizations, artist collectives, research groups, and, lastly, my own work. In the end, I advocate a hybrid form of "Moving Fiction," combining mobile media characters with live actors, music, and sensory input from the surrounding environment.; by Michael Epstein.; Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Comparative Media Studies, 2004.; Includes bibliographical references (leaves [61]-63).

Application of Information and Communications Technology (ICT) to land related projects is now a widespread phenomenon, through both donor-supported interventions and autonomous development. Since the mid-1990s the World Bank has been increasingly involved in ICT land project implementations. The advantages have proven substantial in reducing the time required to complete transactions, improving access to information by the public, as well as other government agencies, reducing the costs of data acquisition, and contributing to standardization of system design. The successful application of ICT to land projects has increased since the 1990s, as lessons from the first tier of programs became clear and were subsequently applied. This note summarizes the demonstrated advantages of ICT application, as well as the key lessons learned. Data acquisition is more feasible and costs less by applying ICT than often-used technology that is quite sophisticated. The use of high, but robust, technology for data acquisition (satellite imagery...

The economy of the Palestinian territories, hampered by years of conflict, occupation, and insecurity remains dependent on foreign aid and the public sector remains the largest employer. Jobs are too few and manufacturing, agriculture, services, including tourism are in decline. As a recent Bank report noted while the Palestinian Authority (PA) has had considerable success in building the institutions of a future state, it has made less progress in developing a sustainable economic base. The recent growth has largely been driven by donor aid. This situation is unsustainable and aid levels have already begun to fall. Fora future Palestinian state to be viable, it is necessary that a private sector led economy is able to generate the jobs needed by a rapidly growing population and the resources required by the government to provide services. Despite multiple challenges in the investment climate, the Palestinian information and communications technology (ICT) sector has managed to grow and integrate with regional and international businesses. It is a fast growing start-up sector...

Immediately following a natural disaster requiring Humanitarian Assistance/Disaster Relief (HA/DR), a myriad of organizations respond. Typically, these early responders send small assessment teams to determine critical needs, which are then paired with the resources available. The needs can range from basic subsistence (food, shelter, and water) to transportation and infrastructure, yet the paramount factor among each team is the need to communicate. To assist in this effort, an Information and Communications Technology (ICT) assessment team using standardized tactics, techniques, procedures and training to maximize effectivenessand comprised of members from multiple organizationscould provide a shared prospective among member groups that could ultimately produce a more objective and complete communications assessment. This in turn, could be transmitted immediately to the global response community via appropriate information sharing portals. As no such model exists at present, our research attempts to pioneer and explore this concept and capability by exploring and providing an outline of an ICT assessment team model. In this thesis, we examine its potential structure, methodologies, and equipment, as well as discuss prospective funding sources...

In this article I examine information and communications technology (ICT) in the context of changes to higher education. My analysis uses Ontario as a case study to illustrate that ICT and the knowledge society discourse is not about technological innovation per se. Rather the discourse legitimates neoliberal reforms to the higher education sector to lay the ground for participation in international markets. That is, these reforms enable privatization of higher education in keeping with pressures exerted by the World Trade Organization (WTO) and the General Agreement on Trade and Services (GATS). The case of Ontario is interesting because of the strategies used to "sell” massive neoliberal reforms to a public that has been, generally speaking, quite protective of its public services. The strategies and mechanisms used to "plug Ontario into the Knowledge Society" reveal how GATS works in local jurisdictions, and contributes to the study of how education within social welfare states comes to take on market characteristics.

Optical communications promise the delivery of high bandwidth service to all types of customers. The potential for optical communications is enormous and has generated excitement and anticipation over the last decade. However, the emergence of a growing market has not materialized and the 1990s communications "bubble" has burst. One result of the bubble burst is that manufacturers of optical components have seen demand for their products plummet and are now struggling to survive. The future of the communications industry depends on its ability to provide better services and higher reliability. At some point, the upward curve of communications demand will require a strong optical components industry to support the industry. If the current stagnation continues, and the manufacturers fail, the economic pillar that is communications will suffer. The MIT Microphotonics Center has initiated a Communications Technology Roadmap study to better understand the technical, economic, and political factors that are inhibiting growth in the optical communications industry. This thesis examines the current state of the optoelectronic manufacturing industry and the causes of the decline. The primary focus is the rampant proliferation of optical transceiver designs resulting from abnormal market conditions during the "boom years" of the 1990s. The transceiver provides send/receiver capabilities and is the major component of optical networks. Convergence...

Network security ensures the consistency, integrity, and reliability of telecommunications systems. Authorized network access prevents fraudulent communications and maintains the availability of the systems. However, limited development time, cost reduction pressure and requirement for high reliability in software development have forced mobile carriers to implement the insufficient and inflexible authentication mechanisms. Technical specifications including network architecture, network protocols, and security algorithm are widely available to the public. In addition, both secured and unsecured networks are interconnected by global roaming services. The inadequate system design will make the mobile systems vulnerable to unauthorized access to mobile communications. Compared with GSM mobile systems, 3G mobile systems are equipped with more robust and flexible security mechanisms. The official position taken by mobile carriers, such as NTT DoCoMo, KDDI, and Vodafone, is that fraudulent communications, usually in the form of cloned mobile phones, are impossible with their 3G mobile systems. Examining the NTT DoCoMo's case, however, we find that this statement is based on weak security assumptions.; (cont.) In order to avoid potential threats and to secure the 3G mobile systems...

"What Voice over Internet Protocol (VoIP) is going to do is start to weaken the foundation of the way we've done things for 100 years...Congress already should be discussing the next telecom bill," said Federal Communications Commission (FCC) Chairman Michael Powell in February 2004, before the United States Senate. The objective of this thesis is to study how VoIP challenges the incumbent US telecommunications act. The appearance of VoIP comes at a juncture when telecommunications system has already turned into a large-scale, complex system with multiple, competing infrastructures. VoIP, however, greatly augments the nested complexity by affording a technology that enables multiple architectures and business models for delivering the same voice (and often converged voice and data) service, while remaining agnostic to the underlying infrastructure. The VoIP-enabled architectures have very different capabilities and costs from one another. Many do not - or cannot - support social regulations such as emergency 911, wiretapping and disability access. Most exploit the economic arbitrage opportunities by evading access charges and universal service contributions.; (cont.) Added to this is the combination of reduced asset specificity due to VoIP's layered architecture and a global standard based ubiquitous IP technology that frees the service providers of the need to own the delivery infrastructure...

This dissertation traces the history of shipboard command and control systems in the United States Navy from 1899, when the service first conducted experiments with wireless telegraphy, through World War II, the conflict which witnessed the birth of the modern shipboard information processing facility. It argues that early-to-mid twentieth century naval officers' development and employment of increasingly sophisticated shipboard command and control systems fundamentally altered the human experience of warfare at sea. Based predominately on archival research, Managing a Sea of Information follows a narrative format. It begins by examining the United States Navy's adoption of radio and challenges the notion that a conservative officer corps failed to appreciate the potential advantages of this new communications technology. The bulk of the study explores the Navy' s development of shipboard command and control systems from World War I through the beginning of World War II, focusing particularly on the efforts of operational commanders to maximize their capabilities through the adoption of devices, methods, and procedures for the collection, processing, and dissemination of information. These efforts gradually changed the nature of command at sea...

Innovations can be the single source of industry's growth. How innovations themselves grow or decline also has a direct affect on the health of the industry in which they play. This thesis looks at fiber optic technologies and their impact on the communications industry. The relative importance of the fiber optic technology is evidenced by its speed and effectiveness in shaping the communications infrastructure in a short period of the recent years. Advent of this relatively new technology, coupled with deregulation policies and the changes in the nature of the network traffic, has caused several disruptions to the communications value chain. Effects of these disruptions and their eventualities are the focus of this thesis. To study these effects, this thesis looks in detail at the interplay of various life cycle stages of innovations and industry. The innovation stages are classified as: Fluid, Transitional, and Specific. Each of these three stages affects the dynamics value chain of the industry in different ways. The characteristics of each stage are studied in detail. There are few innovations that can bring about an impact as extensive as the advent of fiber optics communications has. The review of the processes in the evolution of innovation from birth to potential re- birth provides great insights on the industry's life cycle. The study is based on current theories on the subject of management of technology applied to the communications sector. Most examples and data are based on the telecommunication networks in North America; the timeline of the study is the decade from mid 1990's to present. In closing various strategies in treading the evolution of innovation are described. The evolution life cycle; (cont.) model can be used in several other industries for managing innovation and technologies. Several related research topics are described...
