Public policy and technical communication across the curriculum atthe Colorado School of Mines

Many engineering students are unprepared to address public policy issues because their education is fragmented: they tend to focus narrowly on technical solutions to closed-end problems in engineering and science courses, and they do not see how technical communication relates to either engineering or public policy. A multidisciplinary approach to professional communication which addresses this fragmentation is discussed. In the four-semester engineering practices introductory course sequence (EPICS) program, students learn professional communication skills by working in groups on `real world' projects for which industry and government professionals serve as clients. These open-ended problems involve numerous nontechnical constraints, including a variety of public policy issues. Communication skills and the important connections among competent technical analysis, effective communication, and effective policy formation are reinforced and extended in the policy analysis course and senior design sequence, where students are required to consider and articulate the public policy implications of complex technological projects     

A novel optical burst switching scheme—logical cascaded private subnet with start wavelength assignment policy

Many recent studies have convincingly demonstrated that network traffic exhibits a noticeable self-similar nature, which has a considerable impact on network performance, and most studies of optical burst switching (OBS) networks are under a fundamental assumption that full wavelength conversion is available throughout the network. In practice, however, economic and technical considerations are likely to dictate a more limited and sparse deployment of wavelength converters in the optical network. Therefore, we present a novel scheme for OBS networks, called logical cascaded private subnet (LCPN) with start wavelength assignment policy. We define the concept of canoe relative to cluster in self-similar traffic, and introduce a new device named payload segregator at the edge node as a gateway to the core node in OBS Networks. According to the changes in the edge node framework, we put forward the concept of cluster private subnet and canoe private subnet in the core node correspondingly. A new start wavelength assignment policy is proposed for the absence of (full) wavelength conversion capabilities in the core node of OBS Networks. The performance study indicates that, our new scheme is robust under self-similar traffic and wavelength continuity constraint.     

Evolution of the communications industry in advanced countries: Implication for the policy direction of Korea

After the remarkable growth of the nation's communications industry during the 1980s, the Korean government has progressively introduced the competition principle to the service market. Facing the recent trend of market liberalization together with service globalization widely adopted in advanced countries, the government has now reached a turning point as regards redirecting its communications policy. This article aims to assist Korean policymakers in setting up a new policy direction. Conceptualizing the evolutionary process of the communications industry and grasping the future evolution in advanced countries will surely shed light on the path along which following countries such as Korea are going to move. Doing this work, we specifically emphasize the role of governments in following countries which is quite different from that of forerunners. With these discussions in the background, we suggest a new policy planning process for following countries and, further, go on to derive a technology-oriented globalized policy direction specifically tailored to the Korean communications industry.     

Public policy toward the development and evaluation of devices for the control of diabetes mellitus

Recent research progress toward new technologies for managing diabetes mellitus prompts consideration of related public policy. As guides to this technological development: 1) the potential societal value of specific advances should be estimated; and 2) scientific, commercial, and public concerns should be reflected. In evaluating the new technologies: 1) the cost-effectiveness format for comparing net monetary effects to net health effects seems suitable; 2) the long lead time required to assess many diabetic effects suggests that evaluation of the technologies commence even while their modification continues; 3) a premium is placed on identifying observable short-term effects linked to long-term outcomes; and 4) the placebo effect should be scrutinized. Apace with evaluation of technologies should come evalution and modification of public polices for dealing with them.     

Public trust in a mobile device and service policy in South Korea: The Mobile Device Distribution Improvement Act

South Korea has the highest expenditure on telecommunications among OECD countries, drawing national attention to the issue of reducing high prices. In response, the Korean government enacted the Mobile Device Distribution Improvement (MDDI) Act to eliminate information asymmetry by limiting mobile carriers’ mobile handset subsidies to consumers. This study examined factors affecting public trust in the MDDI based by analyzing responses to a questionnaire survey using the ordered probit model. The results show that the knowledge, expectations, and perceived effects of the MDDI have a meaningful effect on public trust in the policy. The results of this study confirm that it is essential for governments to promote their policies by continuously educating the public, especially in this case because the policy has a direct effect on telecommunications expenditures.     

Public policy must maintain fair competition as its goal[telecommunication industry]

It is argued that if policy makers want true competition, telephone companies, like anybody else, ought to be allowed to bring their best to market. It is concluded that the industry faces many of the same problems that presented themselves ten years ago, with the added problems of constricting regulatory structures that preclude genuine competition
