Purpose: We investigated the effects of threat and trait anxiety on state anxiety and how that affects police officers’ actions during an arrest. Most experiments on police performance under anxiety test the performance of one particular skill. Yet, police work often involves concerted use of a combination of skills. Methods: We created situations – with two different levels of threat – in which officers had to choose and initiate their actions to control and arrest a non-cooperative suspect. We examined whether threat, trait anxiety and state anxiety influenced decision-making (e.g., choosing the appropriate actions) and performance (e.g., quality of communication and the execution of skills). Results: Trait anxiety affected the level of state anxiety, but not any of the decision-making and performance variables. As for decision-making, results showed that only threat determined which action officers took to gain control over the suspect. As for performance, higher levels of state anxiety were accompanied by lower scores of overall performance, communication, proportionality of applied force and quality of skill execution. Conclusion: It is concluded that state anxiety not only impairs performance of single perceptual-motor tasks, but also relevant accompanying skills such as communicating and applying appropriate force. We argue that police training should focus on an integrated set of decision-making and perceptual-motor skills and not just on the performance of isolated motor skills.

Introduction Negative pain-related cognitions are associated with persistence of low-back pain (LBP), but the mechanism underlying this association is not well understood. We propose that negative pain-related cognitions determine how threatening a motor task will be perceived, which in turn will affect how lumbar movements are performed, possibly with negative long-term effects on pain. Objective To assess the effect of postural threat on lumbar movement patterns in people with and without LBP, and to investigate whether this effect is associated with task-specific pain-related cognitions. Methods 30 back-healthy participants and 30 participants with LBP performed consecutive two trials of a seated repetitive reaching movement (45 times). During the first trial participants were threatened with mechanical perturbations, during the second trial participants were informed that the trial would be unperturbed. Movement patterns were characterized by temporal variability (CyclSD), local dynamic stability (LDE) and spatial variability (meanSD) of the relative lumbar Euler angles. Pain-related cognition was assessed with the task-specific ‘Expected Back Strain’-scale (EBS). A three-way mixed Manova was used to assess the effect of Threat, Group (LBP vs control) and EBS (above vs below median) on lumbar movement patterns. Results We found a main effect of threat on lumbar movement patterns. In the threat-condition, participants showed increased variability (MeanSDflexion-extension, p<0.000, η2 = 0.26; CyclSD, p = 0.003, η2 = 0.14) and decreased stability (LDE, p = 0.004, η2 = 0.14), indicating large effects of postural threat. Conclusion Postural threat increased variability and decreased stability of lumbar movements, regardless of group or EBS. These results suggest that perceived postural threat may underlie changes in motor behavior in patients with LBP. Since LBP is likely to impose such a threat, this could be a driver of changes in motor behavior in patients with LBP, as also supported by the higher spatial variability in the group with LBP and higher EBS in the reference condition.

Cybersecurity threat and incident managers in large organizations, especially in the financial sector, are confronted more and more with an increase in volume and complexity of threats and incidents. At the same time, these managers have to deal with many internal processes and criteria, in addition to requirements from external parties, such as regulators that pose an additional challenge to handling threats and incidents. Little research has been carried out to understand to what extent decision support can aid these professionals in managing threats and incidents. The purpose of this research was to develop decision support for cybersecurity threat and incident managers in the financial sector. To this end, we carried out a cognitive task analysis and the first two phases of a cognitive work analysis, based on two rounds of in-depth interviews with ten professionals from three financial institutions. Our results show that decision support should address the problem of balancing the bigger picture with details. That is, being able to simultaneously keep the broader operational context in mind as well as adequately investigating, containing and remediating a cyberattack. In close consultation with the three financial institutions involved, we developed a critical-thinking memory aid that follows typical incident response process steps, but adds big picture elements and critical thinking steps. This should make cybersecurity threat and incident managers more aware of the broader operational implications of threats and incidents while keeping a critical mindset. Although a summative evaluation was beyond the scope of the present research, we conducted iterative formative evaluations of the memory aid that show its potential.

Purpose: Law enforcement may require police officers to inhibit intuitive responses to high threat and thereby affect their emotional reaction and operational effectiveness. Upon this premise, the current study reports two experiments which compare the impact of two relevant shot execution strategies on police officers’ shooting performance under high threat, including (1) fire at an armed assailant and then step away from the assailant's line of fire (‘fire-step’) or (2) step away from the assailant's line of fire and then fire (‘step-fire’). Method: In Experiment 1, 15 experienced police officers performed both shot execution strategies against a stationary assailant who occasionally shot back with coloured soap cartridges (high threat), while we measured their state anxiety, movement times and shot accuracy. In Experiment 2, the same 15 officers remained stationary and fired at the assailant who now performed both shot execution strategies in random order, thereby providing an indication of the risk (i.e., chance to get hit) associated with performing either strategy. Results: Experiment 1 showed that officers preferred using the step-fire strategy and that using this strategy resulted in lower levels of anxiety, increased time for aiming and more accurate shooting than the fire-step strategy. Experiment 2, however, indicated that the step-fire strategy also increases one's chance of getting hit. Conclusions: Findings suggest that inhibition of preferred responses under high threat (as in the fire-step strategy) may increase state anxiety and negatively affect shooting performance in police officers. Future work is needed to reveal underlying mechanisms and explore implications for practice.

Today, we live in a world where every time we turn on our smartphones, we are inextricably tied by data, laws and flowing bytes to different countries. A world in which personal expressions are framed and mediated by digital platforms, and where new kinds of currencies, financial exchange and even labor bypass corporations and governments. Simultaneously, the same technologies increase governmental powers of surveillance, allow corporations to extract ever more complex working arrangements and do little to slow the construction of actual walls along actual borders. On the one hand, the agency of individuals and groups is starting to approach that of nation states; on the other, our mobility and hard-won rights are under threat. What tools do we need to understand this world, and how can art assist in envisioning and enacting other possible futures?This publication investigates the new relationships between states, citizens and the stateless made possible by emerging technologies. It is the result of a two-year EU-funded collaboration between Aksioma (SI), Drugo More (HR), Furtherfield (UK), Institute of Network Cultures (NL), NeMe (CY), and a diverse range of artists, curators, theorists and audiences. State Machines insists on the need for new forms of expression and new artistic practices to address the most urgent questions of our time, and seeks to educate and empower the digital subjects of today to become active, engaged, and effective digital citizens of tomorrow.Contributors: James Bridle, Max Dovey, Marc Garrett, Valeria Graziano, Max Haiven, Lynn Hershman Leeson, Francis Hunger, Helen Kaplinsky, Marcell Mars, Tomislav Medak, Rob Myers, Emily van der Nagel, Rachel O’Dwyer, Lídia Pereira, Rebecca L.

Introduction: Nursing students will come across stressful situations during their internships and will continue to do so in future practice. Because of the impact stress can have on performance, nursing students need to be equipped to work and collaborate in such situations. Careful consideration of the needs and desires of nursing students should be taken in account, in order to create a training environment that fosters students' ability to learn to collaborate under stress. Aim: The aim of this study is to identify viewpoints of undergraduate nursing students towards the learning of collaboration in stressful situations, to understand their needs and desires, and to improve educational designs for training to collaborate in stressful situations. Methods: We conducted a Q-methodology study, a mixed methods approach that studies and charts subjectivity, and uses a by-person factor analytical procedure to create profiles of shared viewpoints. The process of our Q-study is based on the following five steps: Q-set development (54 statements), participant selection (n = 29), Q-sorting procedure, data analysis, and factor interpretation. Results: Q-factor analysis resulted in two prevailing factors that answer our research question. Twenty-five students loaded on these two factors, and factor interpretation resulted in Profile 1 “Practice makes perfect, so let's do it” and Profile 2 “Practice is needed, but it scares me”. Whereas Profile 1 regarded learning to collaborate in stress mainly as a challenge, Profile 2 appeared anxious despite feeling the necessity to learn this. An overarching consensus factor revealed the importance of a learning environment in which mistakes can be made. Discussion: The two described profiles align with the biopsychosocial model of challenge and threat, and could help to recognize and address the individual needs of nursing students when learning to collaborate in stressful situations. Incorporating these profiles in training may guide students towards a more challenge-like appraisal of stressful situations.

In case of a major cyber incident, organizations usually rely on external providers of Cyber Incident Response (CIR) services. CIR consultants operate in a dynamic and constantly changing environment in which they must actively engage in information management and problem solving while adapting to complex circumstances. In this challenging environment CIR consultants need to make critical decisions about what to advise clients that are impacted by a major cyber incident. Despite its relevance, CIR decision making is an understudied topic. The objective of this preliminary investigation is therefore to understand what decision-making strategies experienced CIR consultants use during challenging incidents and to offer suggestions for training and decision-aiding. A general understanding of operational decision making under pressure, uncertainty, and high stakes was established by reviewing the body of knowledge known as Naturalistic Decision Making (NDM). The general conclusion of NDM research is that experts usually make adequate decisions based on (fast) recognition of the situation and applying the most obvious (default) response pattern that has worked in similar situations in the past. In exceptional situations, however, this way of recognition-primed decision-making results in suboptimal decisions as experts are likely to miss conflicting cues once the situation is quickly recognized under pressure. Understanding the default response pattern and the rare occasions in which this response pattern could be ineffective is therefore key for improving and aiding cyber incident response decision making. Therefore, we interviewed six experienced CIR consultants and used the critical decision method (CDM) to learn how they made decisions under challenging conditions. The main conclusion is that the default response pattern for CIR consultants during cyber breaches is to reduce uncertainty as much as possible by gathering and investigating data and thus delay decision making about eradication until the investigation is completed. According to the respondents, this strategy usually works well and provides the most assurance that the threat actor can be completely removed from the network. However, the majority of respondents could recall at least one case in which this strategy (in hindsight) resulted in unnecessary theft of data or damage. Interestingly, this finding is strikingly different from other operational decision-making domains such as the military, police and fire service in which there is a general tendency to act rapidly instead of searching for more information. The main advice is that training and decision aiding of (novice) cyber incident responders should be aimed at the following: (a) make cyber incident responders aware of how recognition-primed decision making works; (b) discuss the default response strategy that typically works well in several scenarios; (c) explain the exception and how the exception can be recognized; (d) provide alternative response strategies that work better in exceptional situations.

Europe is on the path, though rocky, to political and cultural unity. After World War II, relatively large numbers of immigrants moved to Europe and brought with them outside cultural customs and religions. The issue of multiculturalism in society has been on the political agenda for decades, but attitudes have changed drastically since 11th September 2001. Attitudes in relation to migrants, particularly those with a Muslim background, have become more wary and critical. Islam has become associated with violence and terrorism and fears have grown that migration exacerbates this threat to society. These societal developments pose a threat to intercultural education. This article explores the societal situation in the Netherlands and Germany using empirical data and elaborates how youth in the Netherlands and Germany evaluate their relationship with migrant, especially through the dimension of religious tolerance and acceptance.
