In the USA, the Federal Emergency Management Agency (FEMA) provides support to State and local governments in fulfilment of their responsibilities for preparedness, response, recovery and mitigation of disasters. One method FEMA has used to support State and local emergency communication functions was to sign and implement a Memorandum of Understanding with the American Radio Relay League (ARRL) for amateur radio operators to provide electronic communications for State and local governments in disasters. The Federal Communications Commission (FCC) has licensed more than 600,000 amateur radio operators in the USA. The national organization of amateur radio operators called the American Radio Relay League (ARRL) was formed in 1914. More than 80,000 of these amateurs have registered their availability for emergency communications in disasters in the ARRL’s Amateur Radio Emergency Service (ARES). Amateur radio operators have been providing communications in natural disasters such as floods, hurricanes and earthquakes since 1910. Since amateur radio operation was prohibited during the years of both World Wars I and II, FEMA has sponsored a new branch of the amateur service called Radio Amateur Civil Emergency Service (RACES). RACES operators are authorized to operate if the President invokes his War Emergency Powers while all other amateur operation would be silenced. Examines the role of amateur radio in providing emergency electronic communications for disaster management and explores future contributions.

The purpose of this paper is to explore the past events where communication challenges have occurred during a disaster, and events in which amateur radio had played a vital role in creating reliable communication links during the disaster response. Furthermore, this paper identifies the modern technology available with amateur radio operators that can be used to create reliable communication networks in order to meet the high demand of disaster communication.

In this paper the author has conducted an integrative literature review, while analyzing case studies of disasters where communication challenges have occurred and the amateur radio has provided communication support during a disaster response.

In today’s world there is a heavy reliance on centralized communications infrastructure such as cell towers, which are very likely to fail during a disaster. Failure or overload of such infrastructure will cause disruptions in communications and make the disaster response inefficient. Amateur radio does not rely on centralized communications infrastructure, and has the ability to be used to meet the demand during many disaster situations. Thus, it is very important for emergency professionals to understand the value of including amateur radio operators in emergency operations plans.

Research is qualitative in nature, with an aim to write a short paper introducing the issues of Disaster Communications.

This paper is intended to provide an insight about the importance of reliable communications during a disaster. Communication interruptions can create a lot of problems and cause inadequate coordination between response agencies. In order to mitigate such challenges it is crucial to study the vital role of amateur radio in supporting the communications when all other mediums of communication fail.

This paper seeks to contribute to the literature about the resistance to industry technological change in old technology‐based communities of practice.

The paper reports an explanatory case study in order to achieve this purpose: the resistance to technological change of “hams”, the worldwide community of radio amateurs. The case study integrates primary and secondary data and information.

Change agents are critical actors in order to support the adoption of new technology into the community (but not the substitution of the old technology). These actors, in fact, work on the social and learning conditions affecting the process of diffusion of innovation within the “resisting” community.

The paper sheds light on the ambivalent responses to industry technological change in social systems by applying a specific multi‐level theoretical model of analysis about the limits to the diffusion of innovation within social systems.

Briefly reviews previous literature by the author before presenting an original 12 step system integration protocol designed to ensure the success of companies or countries in their efforts to develop and market new products. Looks at the issues from different strategic levels such as corporate, international, military and economic. Presents 31 case studies, including the success of Japan in microchips to the failure of Xerox to sell its invention of the Alto personal computer 3 years before Apple: from the success in DNA and Superconductor research to the success of Sunbeam in inventing and marketing food processors: and from the daring invention and production of atomic energy for survival to the successes of sewing machine inventor Howe in co‐operating on patents to compete in markets. Includes 306 questions and answers in order to qualify concepts introduced.

The study of markets encompasses a number of disciplines – including anthropology, economics, history, and sociology – and a larger number of theoretical frameworks (see Plattner, 1989; Reddy, 1984; Smelser & Swedberg, 1994). Despite this disciplinary and theoretical diversity, scholarship on markets tends toward either realist or constructionist accounts (Dobbin, 1994; Dowd & Dobbin, forthcoming).¹ Realist accounts treat markets as extant arenas that mostly (or should) conform to a singular ideal-type. Realists thus take the existence of markets as given and examine factors that supposedly shape all markets in a similar fashion. When explaining market outcomes, they tout such factors as competition, demand, and technology; moreover, they can treat the impact of these factors as little influenced by context. Constructionist accounts treat markets as emergent arenas that result in a remarkable variety of types. They problematize the existence of markets and examine how contextual factors contribute to this variety. When explaining market outcomes, some show that social relations and/or cultural assumptions found in a particular setting can qualify the impact of competition (Uzzi, 1997), demand (Peiss, 1998), and technology (Fischer, 1992). Constructionists thus stress the contingent, rather than universal, processes that shape markets.

This survey covers civil, electrical and electronics, energy, environment, general, materials, mechanical, and traffic and transportation engineering. Areas such as biomedical and chemical engineering will be dealt with in future issues. Readers may find that the classifications included in this survey are not mutually exclusive but do occasionally overlap with one another. For instance, the section on environmental engineering includes a review of a book on the environmental impact of nuclear power plants, which might as easily have been part of the section on energy technology. Before we go into a discussion of data bases and indexes, I would like to note in this introductory section some recent bibliographic aids published during the period surveyed. Most engineering libraries will find them very valuable in their reference and acquisition functions. Since normal review sources will cover these books, I am merely listing them below: Malinowski, Harold Robert, Richard A. Gray and Dorothy A. Gray.

To build a reference collection of electronics literature, any librarian must sooner or later consult Gretchen Randle's Electronic Industries Information Sources. Published in 1968, it is the only such work available. Times change, however, especially in electronics, and so this article is offered as a supplement to Randle's book.

The aim of this paper is to consider whether it is possible to identify the future spectrum bands most suitable for the Internet of Things (IoT) from the operating factors of a novel set of radio services for a very wide range of applications, as an aid to policy makers now facing decisions in this area.

The approach uses characteristics of spectrum bands against the applications’ requirements to focus on specific major traits that can be matched.

The main choice factors for spectrum are the practical application needs and the network cost model, and these are fairly useful as matching parameters. It is forecast that multiple bands will be needed and that these should be of a licence-exempt form to seed the unfettered innovation of IoT technologies and pre-empt the formation of significant market power by concerned interests.

The way in which spectrum is allocated today will need to be reconsidered, in the light of evolving IoT requirements, which will have increasing economic and social impacts. Policy recommendations for IoT spectrum demands are outlined, and key policy options to ensure a dynamic and trustworthy development of the IoT are put forward. For instance, regulatory barriers globally will need to be removed.

Current interests in the technical requirements of the IoT have not yet given a suitable analysis of the potential spectrum uses, because too often, it is assumed that previous models of spectrum allocation will continue in the future, without consideration of the economic pressures and social context.

New technologies challenge the traditional view that the radio spectrum must be tightly controlled and the new orthodoxy that a market‐based approach is the most efficient way to manage the spectrum. This article aims to make the case for collective use of the spectrum.

The paper draws on a range of literature, both technical and economic, as well as the authors' opinions to describe the economic context, market and other models for spectrum allocation, technological advances in signal processing, and the way forward for assessing future spectrum management policy, with particular reference to Europe.

Technical advances, from research in the commercial domain and from release of military research, combined with the increasingly important economic need to facilitate innovation in new radio technologies, demand a debate on a new approach to spectrum management policy.

The paper brings together the economic and technical arguments in favour of collective use of the radio spectrum and will be of value to academics, business and policy makers.
