Positive human–wildlife coexistence, especially in contexts of rewilding and the reintroduction of large carnivores, partially depends on communication between stakeholders. The media, and in particular local journalism, can play a crucial role in determining people’s knowledge of and attitudes towards wildlife. In this article, we analyse the online coverage of bears produced by the most widely circulated local newspaper in Trentino (Italy), where bears have been reintroduced thanks to a rewilding project funded by the European Union. Employing quantitative and qualitative content analysis of 375 articles, we look into the main features of the media coverage of bears over one year (2024). We find that articles tend to focus on controversial and uncommon events, such as culls and interactions. The most prevalent sources of quotations in the articles are politicians and activists, while experts, local residents, and individuals in the farming sector are less often quoted. The majority of articles are framed through the lens of the socio-political struggle generated by bear presence. Micro-dynamics of the online media coverage include high polarisation, fragmentation of narratives, and the marginalisation of relevant stakeholders (i.e., local communities, experts, European institutions).
Aviation employees operate in a dynamic, complex safety-critical system that is filled with uncertainty, requiring quick and correct expert decision-making. The purpose of this study is to investigate the decision-making indicators among aviation employees. Fifty-five technical engineers and air traffic controllers participated in this study by completing the Cambridge Gambling Task (CGT) at one of Iran’s airports. The CGT provides one of the most reliable and widely used decision-making assessment tasks and related indicators, including decision-making quality, risk-taking, delay aversion, deliberation time, risk adjustment and overall bet ratio. Higher risk adjustment, less deliberation time, and a lower delay aversion index resulted in better decision-making quality. Higher risk-taking does not necessarily mean lower self-control. No significant differences were observed between the studied groups, including between air traffic controllers (both Ground and Tower vs. RADAR and Approach) and between air traffic controllers and technical engineers in the CGT performance. The decision-making quality increased with age and work experience, which has important implications for training and selection processes.
Sixty uncrewed aerial vehicle (UAV) accident reports were analysed to identify causal and contributory factors leading to loss of control in flight – the most prominent category of UAV accident (36%). Design and manufacturing errors were dominant causal factors (22 events, 34%) and contributory factors (18 events, 22%). Recovery was not attempted in the majority of events (35 events, 55%). The relationship between operator age, total hours of experience, experience on type and recovery attempts were analysed. The number of accidents decreased as total hours of experience increased as well as attempted recovery. Using this data, existing accident analysis frameworks HFACS, AcciMap and Accident Route Matrix were applied to a sample of accidents and suitability compared. An adapted version of the Accident Route Matrix – Uncrewed Aerial Vehicle is proposed to assist current and future operators to understand causal and contributory factors to mitigate future loss of control in flight accidents and improve the likelihood of recovery. Using the results of the statistical analysis and the data gathered, a new definition for LOC-I for UAVs was defined by considering the different operating environment of UAVs.
The Aerospace Integration Research Centre (AIRC) at Cranfield University offers industry and academia an open environment to explore the opportunities for efficient integration of aircraft systems. As a part of the centre, Cranfield University, Rolls-Royce, and DCA Design International jointly have developed the Future Systems Simulator (FSS) for the purpose of research and development in areas such as human factors in aviation, single-pilot operations, future cockpit design, aircraft electrification, and alternative control approaches. Utilising the state-of-the-art modularity principles in simulation technology, the FSS is built to simulate a diverse range of current and novel aircraft, enabling researchers and industry partners to conduct experiments rapidly and efficiently. Central to the requirement, a unique, user-experience-centred development and design process is implemented for the development of the FSS. This paper presents the development process of such a flight simulator with an innovative flight deck. Furthermore, the paper demonstrates the FSS’s capabilities through case studies. The cutting-edge versatility and flexibility of the FSS are demonstrated through the diverse example research case studies. In the final section, the authors provide guidance for the development of an engineering flight simulator based on lessons learned in this project.

This chapter explores the moral dimensions of work in emergency and pre-hospital medicine, with an emphasis on protecting the workforce and maintaining optimal functioning of teams. It explores the concepts of moral distress and moral injury from the literature and as they apply to emergency and pre-hospital medicine, but also in the light of the COVID-19 pandemic. It includes reference to the experience of one helicopter emergency medical service (HEMS) organisation attempting to make changes to its culture.
Occupational back-support exoskeletons, categorized as active or passive, hold promise for mitigating work-related musculoskeletal disorders. However, their impact on combined physical and cognitive aspects of industrial work performance remains inadequately understood, especially regarding potential differences between exoskeleton categories. A randomized, counterbalanced cross-over study was conducted, comparing the active CrayX, passive Paexo Back, and a no exoskeleton condition. A 15-min dual task was used to simulate both cognitive and physical aspects of industrial work performance. Cognitive workload parameters included reaction time, accuracy, and subjective measures. Physical workload included movement duration, segmented in three phases: (1) walking to and grabbing the box, (2) picking up, carrying, and putting down the box, and (3) returning to the starting point. Comfort of both devices was also surveyed. The Paexo significantly increased movement duration in the first segment compared to NoExo (Paexo = 1.55 ± 0.19 s; NoExo = 1.32 ± 0.17 s; p < .01). Moreover, both the Paexo and CrayX increased movement duration for the third segment compared to NoExo (CrayX = 1.70 ± 0.27 s; Paexo = 1.74 ± 0.27 s, NoExo = 1.54 ± 0.23 s; p < .01). No significant impact on cognitive outcomes was observed. Movement Time 2 was not significantly affected by both exoskeletons. Results of the first movement segment suggest the Paexo may hinder trunk bending, favoring the active device for dynamic movements. Both devices may have contributed to a higher workload as the movement duration in the third segment increased compared to NoExo.
The main purpose of crew resource management (CRM) is to ensure safe flights by preventing possible errors with the effective use of non-technical skills. The aim of the current study is to examine the effects of CRM on flight safety culture (FSC) with the help of the structural equation model with 451 airline pilots. As a result of the analysis, it was determined that there was a significant correlation between CRM and FSC and that CRM has a significant positive effect on FSC. It has been demonstrated that if CRM awareness and skills are used effectively, the perception of FSC will also improve. Furthermore, these findings indicate that there is a need to progress to the corporate CRM phase, i.e., CRM 7.0, to ensure that organisation-wide FSC awareness is established through CRM awareness.
The relevant growth of human-machine interaction (HMI) systems in recent years is leading to the necessity of being constantly aware of the cognitive workload level of an operator, especially in a safety-critical context such as aviation. Since the confusion in the definition of this concept, this paper clarifies this terminology and also highlights its relationship with stress. Thus, we analysed the state-of-the-art of cognitive workload evaluations, showing three up-to-date methodologies: subjective, behavioural and physiological. In particular, the physiological approach is increasingly gaining attention in the literature due to today’s exponential growth of biomedical sensors. Therefore, a review of the most adopted physiological signals in the workload evaluation is provided, focusing on the aeronautical field. We conclude by highlighting the necessity of a multimodal approach for mental workload assessment as a result of this analysis.
The design of the anesthesia workspace can have an enormous impact on errors, patient safety, and outcomes. Human-centered design (HCD) is a multidisciplinary field focused on how to design spaces and tools to maximize human performance. Bringing the lessons from HCD to the anesthesia workspace can improve patient safety and make clinicians more effective. Two medication safety projects at Seattle Children’s Hospital, new medication trays and a medication template, help to demonstrate how to deploy design principles in the operating room. Future improvements in patient safety in anesthesia will rely upon how providers interact with information systems, clinical tools, and one another, and the quality of these interactions is profoundly influenced by how these systems are designed.
Cognitive engineering is the application of cognitive science to engineering. While the majority of the cognitive models and architectures commonly associated with cognitive engineering were created to understand human behavior, their use in engineering has been carried out with the purpose of realizing better systems. As such, cognitive engineering model fidelity varies, based on application goals. This chapter provides readers with a history of cognitive modeling in cognitive engineering and its diverse contributions by reviewing the seminal work of Card, Moran, and Newell, which laid the foundations for many developments. It then examines the use of cognitive models in complex systems engineering. The chapter concludes with a summary and a discussion of potential threats and future advances.
There is an increasing recognition that non-technical skills, such as teamwork, communication and interpersonal competencies, provide the foundation of any cardiac surgery program.Understanding the human and psychological factors at play can help teams make the transition from good patient care to excellent patient care. This chapter will focus on those human, environmental and cultural factors that can be leveraged to optimize team performance with a focus on perfusion practice.

This book provides a clinically-focused tutorial with chapters spanning the technical aspects, patient related considerations, and human factors essential to contemporary practice of cardiopulmonary bypass. Written concisely to allow the reader to gain and apply critical knowledge to the clinical setting and featuring artwork that has been extensively updated to include numerous figures and color plates imbedded into each chapter. A remarkable collection of international experts in the fields of perfusion, anesthesiology, and cardiac surgery were recruited to co-author chapters, providing a multidisciplinary approach to case management. This completely updated edition includes expanded content on developments in minimally invasive extracorporeal circulation, anticoagulation, organ injury, and human factors. The comprehensive coverage of perfusion practice in a concise, highly illustrated format makes it the go-to, portable reference manual for perfusionists, cardiac surgeons, and anesthesiologists.
The aim of this study was to examine safety-related contamination threats and risks to health-care workers (HCWs) due to the reuse of personal protective equipment (PPE) among emergency department (ED) personnel.
Methods:
We used a Participatory Design (PD) approach to conduct task analysis (TA) of PPE use and reuse. TA identified the steps, risks, and protective behaviors involved in PPE reuse. We used the Centers for Disease Control and Prevention (CDC) guidance for PPE donning and doffing specifying the recommended task order. Then, we convened subject matter experts (SMEs) with relevant backgrounds in Patient Safety, Human Factors and Emergency Medicine to iteratively identify and map the tasks, risks, and protective behaviors involved in the PPE use and reuse.
Results:
Two emerging threats were associated with behaviors in donning, doffing, and re-using PPE: (i) direct exposure to contaminant, and (ii) transmission/spread of contaminant. Protective behaviors included: hand hygiene, not touching the patient-facing surface of PPE, and ensuring a proper fit and closure of all PPE ties and materials.
Conclusions:
TA was helpful revealed that the procedure for donning and doffing of re-used PPE does not protect ED personnel from contaminant spread and risk of exposure, even with protective behaviors present (e.g., hand hygiene, respirator use, etc.). Future work should make more apparent the underlying risks associated with PPE use and reuse.
This chapter explore human factors, also known as ergonomics, which is an established scientific discipline that has become integral in healthcare in recent years. The catalyst for this in the UK was the Clinical Human Factors Group led by Martin Bromiley. Martin’s wife Elaine died following errors made during a routine operation when the theatre team failed to respond appropriately to an unanticipated anaesthetic emergency in part because of a variety of human factors. There is still confusion around the term ‘human factors’. This is partly because human factors cannot be explored in isolation but need to be understood in the context of human activity, error, and the culture around error.
Professor Marc de Leval (16 April 1941 –26 June 2022) was a pioneer in the field of congenital cardiothoracic surgery and former chair of the British Congenital Cardiac Association [https://www.bcca-uk.org/]. Professor de Leval was appointed as a Consultant Cardiothoracic Surgeon at Great Ormond Street Hospital in 1974. Throughout his distinguished career at Great Ormond Street Hospital, he worked with dedication to improve outcomes for cardiothoracic surgery. His contribution to academic cardiothoracic surgery was significant and far-reaching with over 300 peer-reviewed publications. Of particular note was his work in improving the palliation of children with cyanotic congenital heart disease by the use of the modified Blalock-Thomas-Taussig shunt and his pioneering work over many years to improve understanding of the Fontan circulation using in vitro modelling and computational fluid dynamics that led to the development of the total cavopulmonary connection. His other significant contributions include the importance of analysing surgical failures, being the co-editor of the most readable textbook in our field, and so much more. During his career, he trained many eminent surgeons from around the world, and a Marc de Leval Fellowship of The American Association for Thoracic Surgery [https://www.aats.org/about-the-foundation/the-reach-of-our-programs/foundation-honoring-our-mentors-program/marc-r-de-leval-md] now allows the opportunity for a trainee to study congenital cardiac surgery in the UK or Europe. Marc is fondly remembered by the staff at Great Ormond Street Hospital. The nurses recall his arrival at the break of day on the intensive care unit, having already been for a swim, and the diligence with which he observed his patients following surgery. Former trainees remember a man who, despite his standing, always remained courteous, approachable, and kind. Professor de Leval will be remembered not only as a skilled and dedicated surgeon but also as a distinguished scholar, one with a quest for knowledge in the pursuit of excellence.
This manuscript is a personal tribute to Professor Marc de Leval from two of his colleagues: Professor Martin J. Elliott and Professor John E. Deanfield. As stated by the authors: “Marc’s career history is presented in the accompanying eulogy from the current Heart & Lung Team at Great Ormond Street Hospital (GOSH), allowing us to highlight Marc’s personal qualities that made him such an inspirational colleague. … Marc was, as we have said, the cardiologist’s surgeon. He was also the surgeon’s cardiologist, bridging the two disciplines and fusing the team. He was delighted by the advent of interventional cardiology and did not see it as a threat or competition, but instead, as appropriate for the well-being of his patients. He recognised how traumatic surgery could be for patients and their families and sought to avoid it whenever possible by alternative treatments. Marc will be remembered with love and admiration by his many patients and their families, whose lives he changed. His technical skill, energy, devotion, humour, intellect and influence will be sorely missed. May he rest in peace.”
This chapter discusses the human factors foundations of trust, specifically human-automation trust. Trust in automation can be conceptualized as a three-factor model consisting of the human trustor, the automated trustee, and the environment or context. In this model, qualities of the human (such as experience), work with qualities of the robot (such as form) in an environment that also influences the nature of the interaction. Since trust is constantly evolving, time itself is also a facet of trust in human-automation interactions. Measurement of trust is challenging because trust itself is a latent variable, and not directly observable. However, measurement is necessary to ensure trust is appropriately calibrated and there is not a mismatch between the trustors’ expectations, and the trustees’ capabilities. Trust measures include self-report or survey-type measures, behavioral observations, and biological measures.
Investigating the underlying predictors of speeding behaviour deserves the full attention of research. This study aims to examine the effects of demographic variables on the perceived deterrent mechanisms and to predict speeding behaviour to target appropriate prevention programmes. In this study, 212 randomly selected drivers having a valid car driving licence participated in an online survey. The results revealed that demographic variables influenced drivers’ perceptions towards social and legal sanctions as well as material loss. The model revealed that two sanction-related constructs, that is, legal sanction (b = −0⋅227, P = 0⋅007) and material loss (b = −0⋅218, P = 0⋅005), as well as lax perception towards traffic accident (b = −0⋅176, P = 0⋅025), were the significant predictors of speeding behaviour. These findings suggested that prevention programmes should prioritise young and single drivers. The most effective targeted prevention programmes are highlighted accordingly based on the study results.
Although the term ‘tracheostomy’ simply means a hole entering the trachea, it can be usefully divided into tracheostomy (in which a hole is made between the anterior neck and the trachea, which remains otherwise intact) and laryngectomy (in which the larynx is removed and the trachea is joined to the neck as a blind-ending stoma). Both groups of patients have an increased risk of complications outside and within hospitals. Many of these are entirely avoidable by better knowledge and reliability of care. There is confusion about different types of tracheostomy and between management of complications of tracheostomy and laryngectomy stoma. There is a need for clear understanding of the differences and what represents good care of such patients and their airways. Complications include airway blockage and displacement. Harm may occur if airway emergencies are not managed promptly and in a structured manner. Standard operating procedures, algorithms and checklists have a role in improving reliability of care and approaches to emergencies. Recent evidence shows multidisciplinary teams using quality improvement principles can reduce complications, hasten decannulation and improve patient experience. The National Tracheostomy Safety Project and the Global Tracheostomy Collaborative have been established to improve education and safety of tracheostomy care.
Human factors can be defined as the science of understanding of interactions among humans and other elements of a system, and how they can be adapted to improve performance and safety. Human factors issues were present in 40% of the cases of major complications in airway management in NAP4. Human factors issues can be considered in terms of ‘threats’ and ‘safeguards’. Threats increase the likelihood of the occurrence of an error that results in patient harm while safeguards help prevent this. Threats and safeguards in relation to human factors in airway management refer not only to ‘non-technical skills’ (e.g. situation awareness, teamwork) but also many other factors such as procedures, staffing and the physical environment in which airway management is conducted. Proper attention to human factors related issues contributes to both the prevention and effective management of airway emergencies and requires that these issues are considered as part of an integrated approach at the level of the individual, team, environment and organisation as part of routine airway care – not only when an emergency arises.
