Petro-HRA is a method for qualitative and quantitative assessment of human reliability in the oil and gas industry. The method allows systematic identification, modelling and assessment of tasks that affect major accident risk. The method is mainly intended for use within a quantitative risk analysis (QRA) framework, but may also be used as a stand-alone analysis. Petro-HRA should be used to estimate the likelihood of human failure events (HFEs) in post-initiating event scenarios.

  • Physiological Self Regulation With
    PHYSIOLOGICAL SELF REGULATION WITH BIOFEEDBACK GAMES A Dissertation by AVINASH RAO PARNANDI Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Ricardo Gutierrez-Osuna Committee Members, Tracy Hammond Dylan Shell Thomas Ferris Head of Department, Dilma Da Silva May 2017 Major Subject: Computer Engineering Copyright 2017 Avinash Parnandi ABSTRACT Mental stress is a global epidemic that can have serious health consequences including cardiovascular diseases and diabetes. Several techniques are available to teach stress self-regulation skills including therapy, meditation, deep breathing, and biofeedback. While effective, these methods suffer from high drop-outs due to the monotonic nature of the exercises and are generally practiced in quiet relaxed environment, which may not transfer to real-world scenarios. To address these issues, this dissertation presents a novel intervention for stress training using games and wearable sensors. The approach consists of monitoring the user’s physiological signals during gameplay, mapping them into estimates of stress levels, and adapting the game in a way that promotes states of low arousal. This approach offers two key advantages. First, it allows users to focus on the gameplay rather than on monitoring their physiological signals, which makes the training far more engaging. More importantly, it teaches users to self-regulate their stress response, while performing a task designed to increase arousal. Within this broad framework, this dissertation studies three specific problems. First, the dissertation evaluates three physiological signals (breathing rate, heart rate variability, and electrodermal activity) that span across the dimensions of degrees of selectivity in measuring arousal and voluntary control in their effectiveness in lowering arousal.

Evaluating the Effectiveness of Graduated Stress Exposure in Virtual Spaceflight Hazard Training Abstract Psychological and physiological stress experienced by astronauts can pose risks to mission success. In clinical settings, gradually increasing stressors help patients develop resilience. It is unclear whether graduated stress exposure can affect responses to acute stressors during spaceflight. This study evaluated psychophysiological responses to potentially catastrophic spaceflight operation, with and without graduated stress exposure, using a virtual reality environment.

The vast majority of Great War historians have ignored the presence of mounted troops on the Western Front, or have written off the entire cavalry arm with a single word – ‘obsolete.’ However, the Canadian Cavalry Brigade and the Canadian Light Horse remained on the Western Front throughout the Great War because cavalry still had a role to play in modern warfare.

  • PERFORMANCE UNDER STRESS Human Factors in Defence
    PERFORMANCE UNDER STRESS Human Factors in Defence Series Editors: Dr Don Harris, Cranfield University, UK Professor Neville Stanton, Brunel University, UK Professor Eduardo Salas, University of Central Florida, USA Human factors is key to enabling today’s armed forces to implement their vision to ‘produce battle-winning people and equipment that are fit for the challenge of today, ready for the tasks of tomorrow and capable of building for the future’ (source: UK MoD). Modern armed forces fulfil a wider variety of roles than ever before. In addition to defending sovereign territory and prosecuting armed conflicts, military personnel are engaged in homeland defence and in undertaking peacekeeping operations and delivering humanitarian aid right across the world. This requires top class personnel, trained to the highest standards in the use of first class equipment. The military has long recognised that good human factors is essential if these aims are to be achieved. The defence sector is far and away the largest employer of human factors personnel across the globe and is the largest funder of basic and applied research. Much of this research is applicable to a wide audience, not just the military; this series aims to give readers access to some of this high quality work. Ashgate’s Human Factors in Defence series comprises of specially commissioned books from internationally recognised experts in the field. They provide in-depth, authoritative accounts of key human factors issues being addressed by the defence industry across the world. Performance Under Stress Edited by PETER A. HANCOCK and JAMES L.

  • Stress Exposure Training
    8 Stress Exposure Training James E. Driskell and Joan H. Johnston Imagine that you are assigned a task to sit at your desk and mentally add a series of numbers. Now, imagine that you invite several people into your office, turn a radio and television on, and have someone flick the light switch on and off. For good measure, let’s let through all those calls from telephone salespeople asking you to switch your phone service. Further- more, let’s add some consequences to the task If your calculations are incorrect, you must pay a penalty of $1 for each number that you are off. It is difficult enough to perform even a moderately complex task in a nor- mal or benign performance environment, as the literature on training and skill acquisition attests. However, it would be far more difficult to perform a task effectively under the high-stress or high-demand conditions of this imaginary scenario. The military offers numerous real-world examples of complex and de- manding task environments. Today’s ships, airplanes, and tanks are tech- nologically advanced systems that greatly extend the range of human ca- pabilities. For example, military anti-air warfare systems aboard modern naval ships allow military personnel to detect aircraft at great distances. On the other hand, these systems also increase the demands on the op- erator: The amount and complexity of information that must be processed in a short period of time once a target has been detected is enormous. Therefore, although modern military systems have greatly extended the military’s capabilities, they have both increased the stress under which personnel must perform and increased the potential for catastrophic er- rors.

  • The Air Defence Task: Understanding What Motivates Automation Usage to Support Classification Decisions in Practice
    The Air Defence Task: Understanding what motivates automation usage to support classification decisions in practice Thesis submitted in accordance with the requirements of the University of Liverpool for the degree of Doctor in Philosophy by Chlo¨eBarrett-Pink June 2018 2 Abstract With the growing use of automated systems in military environments it remains vital that research continues to explore the use of such systems operationally. The recent literature has tended to take a systems focused approach, which has concentrated on features of the system and what impact alterations have upon task performance. How- ever, research has begun to see the value in taking a human-centred perspective to understanding the use of automated systems in military environments; asking research questions that remain focused on the human operators that are required to utilise auto- mated systems in increasingly complex environments. Therefore, this thesis contributes to the literature on human-machine-interaction through exploring the operational use of automated systems in the maritime environment. Research into sociotechnical sys- tems is complex, therefore this thesis adopted a Naturalistic Decision Making (NDM) approach utilising mixed-methods to elicit understanding and knowledge from unique access to Royal Navy (RN) Subject Matter Experts (SME). Privileged access to a large number of RN experts (N =53) enabled novel and interesting findings to be drawn from two qualitative surveys. The first explored the stages of the air defence task conducted by RN personnel to better understand where uptake of automation may be beneficial. The findings of this questionnaire revealed that the high-level stages of the air defence task (Observe, Identify and Classify, and Decide and Act) have remained unchanged over the last 20 years and the areas that have previously been identified as potentially benefiting from automated system support remain the same.
