It's good to talk: performing and recording the telephone interview

This paper explores the transition of talk to text in the process of performing and recording semi-structured interviews over the telephone. In particular, it considers the ways respondents and the materials enjoined in the process of interviewing exceed their role in the research process. Drawing on my experience of conducting telephone interviews in the UK, I position the interview as an uncertain encounter: one framed by earlier narrations as much as the aims and objectives of the research project; and an orientation towards 'talk' as much as the reduction of performance to text. Far from losing track of these uncertainties I argue that tape-recorders are well equipped to document these in/audible realms.

Local Tsunami Warning in the Pacific Coastal United States

Coastal areas are warned of a tsunami by natural phenomena and man-made warning systems. Earthquake shaking and/or unusual water conditions, such as rapid changes in water level, are natural phenomena that warn coastal areas of a local tsunami that will arrive in minutes. Unusual water conditions are the natural warning for a distant tsunami. Man-made warning systems include sirens, telephones, weather radios, and the Emergency Alert System. Man-made warning systems are normally used for distant tsunamis, but can be used to reinforce the natural phenomena if the systems can survive earthquake shaking. The tsunami warning bulletins provided by the West Coast/Alaska and Pacific Tsunami Warning Centers and the flow of tsunami warning from warning centers to the locals are critical steps in the warning process. Public knowledge of natural phenomena coupled with robust, redundant, and widespread man-made warning systems will ensure that all residents and tourists in the inundation zone are warned in an effective and timely manner.

CELLULAR TOWER PROLIFERATION IN THE UNITED STATES

ABSTRACT. Since the early 1980s the growing popularity of cellular communication has wrought dramatic landscape changes on the American scene through an invasion of thousands of cellular telephone towers. Objections raised to new tower construction by local residents, interest groups, and regulatory boards range from visual impacts to perceived health risks. This essay traces the origins of wireless telephony, its proliferation across the United States, and the visual impacts associated with tower construction. Three stages in the geographical expansion of wireless networks are identified.     

Monitoring Controversial Environmental/Natural Resource Issues: Differential Effects of Telephone and Mail Surveys

Monitoring public opinion, especially about controversial environmental/natural resource issues, through various survey modes remains an important social science tool used by scholars, advocates, newspaper reporters, and policymakers alike. However, with this use there has been a concomitant decline in response rates. To address this problem, increased use of mixed modes of surveys has occurred. The degree to which results of different modes can be combined remains a basic question. Can findings be compared to assess changes in public views across time or differences among various regions when different modes of data collection are used? We addressed this question by assessing how two comparable samples of residents' responses to the same questions differed depending upon survey mode (telephone or mail) while controlling for sampling procedures and survey content.
