<p>The development of computerised information systems for large scale emergency management is lacking. These systems could present information and support information transfer across shifts. This is important as providing timely information is critical for efficient search and rescue operations in an emergency environment. This thesis contributes the design and prototype implementation for an interactive visualisation, called RescueTime, which is then evaluated. The evaluation showed that RescueTime is as effective as a traditional tool used by emergency managers. This demonstrates the feasibility of designing and developing larger information systems, for the purpose of emergency management.</p>

Purpose The purpose of this paper is to present a statistical analysis of research into emergency management (EM) using information systems (IS) for the period 2000-2016. Design/methodology/approach In this study, research trends in the area of EM using IS are analysed using various parameters, including trends on publications and citations, disciplinary distribution, journals, research institutions and regional cooperation. Through a keyword co-occurrence analysis, this study identifies the evolution of the main keywords in this area, and examines the changes and developments in the main focus of scholars in this period. The study also explores the main research orientations in the field by analysing and integrating the results of two cluster analyses conducted from keyword- and reference-based perspectives, respectively. Findings The area of EM using IS has received increased attention and interest by researchers and practitioners. It is suggested that more cooperation among research institutions is required to help facilitate the further development of the area. Six main research orientations are identified: namely Web 2.0-enabled research, geographic information technology (IT), IT-based research, the contextual use of IT, crisis collaboration research and mass media communication research, since the research area first became popular in 2006. Originality/value This study is the first to comprehensively map the landscape of EM by conducting a bibliometric analysis of the research using IS. The authors’ findings can help academics and emergency managers gain a comprehensive understanding of the research area, and guide scholars towards producing more effective findings.

Purpose – This paper aims to develop a conceptual model for future theory building and provides guidance to emergency managers by identifying important organizational factors influencing emergency response performance. Design/methodology/approach – A conceptual framework is developed linking organizational characteristics and incident types to emergency response performance, focusing on the “prepare” and “respond” stages in emergency management. Archival data are used to test the framework, using ANOVA to analyze 12,057 incidents over a nine-year period. Findings – The results indicate that organizational characteristics impact emergency response performance through Knowledge of Location. Several organizational factors impact Knowledge of Location, which then serves, with incident type, as a significant indicator for emergency response performance. Research limitations/implications – Researchers are constrained by the data collected in the database used for the study; however, the use of this commonly collected data to operationalize our variables for model testing facilitates analysis of other emergency management organizations for validation. Future model extension is possible by identifying other important variables. Practical implications – The analysis emphasizes the importance of area familiarization training in improving emergency response as well as the impact of organizational structure changes on response. Emergency managers should ensure clear lines of authority and communication during times of change. Originality/value – This is one of the few studies to use empirical data from a large-scale, real-world database to study emergency response performance. In contrast to previous modeling-based research, this study emphasizes organizational characteristics with an empirical perspective.

The study of computing infrastructures has grown significantly due to the rapid proliferation and ubiquity of large-scale IT-based installations. At the same time, recognition has also grown of the usefulness of such studies as a means for understanding computing infrastructures as material complements of practical action. Subsequently the concept of “infrastructure” (or “information infrastructures,” “cyberinfrastructures,” and “infrastructuring”) has gained increasing importance in the area of Computer-Supported Cooperative Work (CSCW) as well as in neighboring areas such as Information Systems research (IS) and Science and Technology Studies (STS). However, as such studies have unfolded, the very concept of “infrastructure” is being applied in different discourses, for different purposes, in myriad different senses. Consequently, the concept of “infrastructure” has become increasingly muddled and needs clarification. The chapter presents a critical investigation of the vicissitudes of the concept of “infrastructure” over the last 35 years.

ABSTRACT A convenient method is described for the intracistronic mapping of genetic sites responsible for electrophoretic variation of a specific protein in Drosophila melanogaster. A number of wild-type isoalleles of the rosy locus have been isolated which are associated with the production of electrophoretically distinguishable xanthine dehydrogenases. Large-scale recombination experiments were carried out involving null enzyme mutants induced on electrophoretically distinct wild-type isoalleles, the genetic basis for which is followed as a nonselective marker in the cross. Additionally, a large-scale recombination experiment was carried out involving null enzyme rosy mutants induced on the same wild-type isoallele. Examination of the electrophoretic character of crossover and convertant products recovered from the latter experiment revealed that all exhibited the same parental electrophoretic character. In addition to documenting the stability of the xanthine dehydrogenase electrophoretic character, this observation argues against a special mutagenesis hypothesis to explain conversions resulting from allele recombination studies.
