    Get PDF
    Purpose – This paper aims to argue that to address the consequences of climate change and variability a greater focus on pre-emergency planning that engages a wider stakeholder group must be adopted. Design/methodology/approach – The paper discusses UK emergency management and approaches to climate change and climate variability risk. Findings – The internal focus of UK emergency management inhibits the contribution that it can make to societal resilience and public preparedness. Effective risk reduction requires that all actors, including the public, are engaged in the social learning process. From a UK emergency management perspective this requires a culture shift to an outward proactive focus. Originality/value – This paper offers insights into emergency preparedness in the UK

    The ergonomics of command and control

    Since its inception, just after the Second World War, ergonomics research has paid special attention to the issues surrounding human control of systems. Command and Control environments continue to represent a challenging domain for Ergonomics research. We take a broad view of Command and Control research, to include C2 (Command and Control), C3 (Command, Control and Communication), and C4 (Command, Control, Communication and Computers) as well as human supervisory control paradigms. This special issue of ERGONOMICS aims to present state-of-the-art research into models of team performance, evaluation of novel interaction technologies, case studies, methodologies and theoretical review papers. We are pleased to present papers that detail research on these topics in domains as diverse as the emergency services (e.g., police, fire, and ambulance), civilian applications (e.g., air traffic control, rail networks, and nuclear power) and military applications (e.g., land, sea and air) of command and control. While the domains of application are very diverse, many of the challenges they face share interesting similarities

    A design for an intelligent monitor and controller for space station electrical power using parallel distributed problem solving

    The emphasis is on defining a set of communicating processes for intelligent spacecraft secondary power distribution and control. The computer hardware and software implementation platform for this work is that of the ADEPTS project at the Johnson Space Center (JSC). The electrical power system design which was used as the basis for this research is that of Space Station Freedom, although the functionality of the processes defined here generalize to any permanent manned space power control application. First, the Space Station Electrical Power Subsystem (EPS) hardware to be monitored is described, followed by a set of scenarios describing typical monitor and control activity. Then, the parallel distributed problem solving approach to knowledge engineering is introduced. There follows a two-step presentation of the intelligent software design for secondary power control. The first step decomposes the problem of monitoring and control into three primary functions. Each of the primary functions is described in detail. Suggestions for refinements and embelishments in design specifications are given

    Improving emergency and disaster response management performance : A problem-solving perspective

    Get PDF
    The purpose of this doctoral thesis is to investigate how collective emergency and disaster response management performance can be further improved. Based on four studies, this research contributes with knowledge in two areas.First, collective processes that might improve response management are investigated. In this regard, collective improvisation as a concept is found limited in its usefulness and it is suggested to adopt problem solving as a broader analytical concept. In specific, collective problem representation is argued as potentially useful for investigating how response management performance can be improved. One interview study and one document study explore collective problem representation in response management. Based on interviews with response management professionals, three factors are found to impact the process of achieving a collective problem representation: formal hierarchical structures, legislation and regulations, and, relationships. How problems are represented in common operational pictures, which are widely used for sharing information about problems and solutions in responsemanagement is investigated in an empirical study of a wildfire response. Problems were found to be mainly represented in terms of geographic references and the status of the present wildfires, statements regarding resources, and, in terms of risks or potential consequences, relating to anticipated or future problems. Understandinghow problems are represented in common operational pictures enables an investigation into how these can be improved to better inform the handling of various events. The second area of contribution concerns how we can identify measures that actually improve response management performance. A complementary approach to traditional response management research is suggested: that of combining descriptive and experimental research. Descriptive studies constitute a basis for understandingresponse management problems and suggesting possible solutions. Experiments can thereafter test and evaluate the suggested solutions to see whether these should be further developed. The suggested research approach is exemplified with an experimental study testing a recommended measure in response management practice, namely goal alignment. Even though the findings indicate that goal alignment might not be an effective solution to improve response management performance, further inquiry is warranted. This thesis nevertheless calls for caution whenattributing causal explanation for successful performance to concepts without thoroughly investigating cause and effect between the two, which is supported by the findings related to collective improvisation and goal alignment. A useful way forward can be that of developing articulated models, which should describe the essential performance of the concept in question and have clear, falsifiable, connections between the concept and the outcome

    This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

    Integration of professional judgement and decision-making in high-level adventure sports coaching practice

    This study examined the integration of professional judgement and decision-making processes in adventure sports coaching. The study utilised a thematic analysis approach to investigate the decision-making practices of a sample of high-level adventure sports coaches over a series of sessions. Results revealed that, in order to make judgements and decisions in practice, expert coaches employ a range of practical and pedagogic management strategies to create and opportunistically use time for decision-making. These approaches include span of control and time management strategies to facilitate the decision-making process regarding risk management, venue selection, aims, objectives, session content, and differentiation of the coaching process. The implication for coaches, coach education, and accreditation is the recognition and training of the approaches that“create time” for the judgements in practice, namely“creating space to think”. The paper concludes by offering a template for a more expertise-focused progression in adventure sports coachin

    Visual analytics for supply network management: system design and evaluation

    Full text link
    We propose a visual analytic system to augment and enhance decision-making processes of supply chain managers. Several design requirements drive the development of our integrated architecture and lead to three primary capabilities of our system prototype. First, a visual analytic system must integrate various relevant views and perspectives that highlight different structural aspects of a supply network. Second, the system must deliver required information on-demand and update the visual representation via user-initiated interactions. Third, the system must provide both descriptive and predictive analytic functions for managers to gain contingency intelligence. Based on these capabilities we implement an interactive web-based visual analytic system. Our system enables managers to interactively apply visual encodings based on different node and edge attributes to facilitate mental map matching between abstract attributes and visual elements. Grounded in cognitive fit theory, we demonstrate that an interactive visual system that dynamically adjusts visual representations to the decision environment can significantly enhance decision-making processes in a supply network setting. We conduct multi-stage evaluation sessions with prototypical users that collectively confirm the value of our system. Our results indicate a positive reaction to our system. We conclude with implications and future research opportunities.The authors would like to thank the participants of the 2015 Businessvis Workshop at IEEE VIS, Prof. Benoit Montreuil, and Dr. Driss Hakimi for their valuable feedback on an earlier version of the software; Prof. Manpreet Hora for assisting with and Georgia Tech graduate students for participating in the evaluation sessions; and the two anonymous reviewers for their detailed comments and suggestions.

    Quantitative assessment of medical student learning through effective cognitive Bayesian representation

    Get PDF
    The changes of learning environments and the advancement of learning theories have increasingly demanded for feedback that can describe learning progress trajectories. Effective assessment should be able to evaluate how learners acquire knowledge and develop problem solving skills. Additionally, it should identify what issues these learners have during the learning processes and why they have these issues. This study depicts visual representations of cognitive tasks as crucial points to connect learning and assessment. This study is an exploration of these cognitive tasks in complex learning environments and a quantitative representation of these measureable objects in cognitive structures.published_or_final_versio

    Viewfinder: final activity report

    The VIEW-FINDER project (2006-2009) is an 'Advanced Robotics' project that seeks to apply a semi-autonomous robotic system to inspect ground safety in the event of a fire. Its primary aim is to gather data (visual and chemical) in order to assist rescue personnel. A base station combines the gathered information with information retrieved from off-site sources. The project addresses key issues related to map building and reconstruction, interfacing local command information with external sources, human-robot interfaces and semi-autonomous robot navigation. The VIEW-FINDER system is a semi-autonomous; the individual robot-sensors operate autonomously within the limits of the task assigned to them, that is, they will autonomously navigate through and inspect an area. Human operators monitor their operations and send high level task requests as well as low level commands through the interface to any nodes in the entire system. The human interface has to ensure the human supervisor and human interveners are provided a reduced but good and relevant overview of the ground and the robots and human rescue workers therein
