Trust Dispersion and Effective Human-AI Collaboration: The Role of Psychological Safety (Short Paper)

Trust is a crucial factor in team performance for human-human and human-AI teams. While research made significant advancements in uncovering factors that affect the human decision to trust their AI teammate, it disregards the potential dynamics of trust in teams with multiple team members. To address this gap, we propose that trust in AI is an emergent state that can be differentiated on the individual and team level. We highlight the importance of considering the dispersion of trust levels in human-AI teams to understand better how trust influences team performance. Furthermore, we transfer the concept of psychological safety from human psychology literature and propose its role in buffering the potential adverse effects of dispersed trust attitudes

Etude exploratoire de l'homophobie au sein du football masculin amateur en FWB

peer reviewedDespite the implementation of some campaigns to fight against the phenomenon, in professional football stadiums, manifestations of homophobia are still regularly making headlines. Moreover, several French and Anglo-Saxon studies conducted within grassroots football report greater hostility towards homosexuality in this context than in other contexts of everyday life. Unfortunately, however, there is still very little information about this topic in the Wallonia-Brussels Federation (WBF). The aim of this study was to find out how homophobia expresses itself in WBF men's amateur football; to question different stakeholders in grassroots football about the role they might play regarding this problematic, and; analyze the actions that are currently being taken to tackle it. A total of 511 male amateur football stakeholders completed an online questionnaire. Based on their experiences or feelings, they answered questions regarding manhood, insults related to homosexuality, the role of each person in dealing with homophobia, and the positions taken by the football federation and the football clubs in relation to this issue. Afterwards, nine other people were interviewed in order to discuss the results of the questionnaire and to provide more details. Data underline that although acceptance of homosexuality is almost unanimous, the use of insults referring to homosexuality is common, and the belief that a homosexual person would not be masculine enough to play football is still widespread. The various stakeholders in grassroots football are poorly informed about the federation's anti-discrimination policy, while clubs rarely have a clear policy on discrimination. At both federation and club levels, it is important to give visibility to the efforts made in tackling homophobia. All actors of the WBF football should be made aware of the importance of showing their acceptance of homosexuality in order to promote a general atmosphere of inclusion in football.5. Gender equalit

Urban Sport-for-Development Initiatives and Young People in Socially Vulnerable Situations: Investigating the ‘Deficit Model’

Critical scholars have indicated that the assumptions underlying most sport-for-development (SFD) initiatives tend to align with a ‘deficit model’ of youth: young people from disadvantaged areas are uniformly deficient and in need of development, which can be achieved through sport (Coakley, 2011; Coalter, 2013). In this article, we investigated these assumptions within six urban SFD initiatives that work with young people in socially vulnerable situations in a ‘first’ world nation, Belgium. We conducted a survey at two moments in time amongst 14- to 25-year-old participants in order to test two assumptions: i) ‘participants are deficient and in need of development’; and ii) ‘participation in SFD initiatives leads to positive personal development’. We operationalised ‘development’ as the commonly used outcomes of perceived self-efficacy and self-esteem. These are ‘household words’ both inside and outside SFD research, practice, and policy and carry the assumption that boosting them will by itself foster positive outcomes. The findings refute the supposition that young people from disadvantaged urban areas are uniformly in need of more perceived self-efficacy and self-esteem and show that there is no simple and predictable change in participants’ ‘development’. We suggest that, in designing and researching programs, SFD stakeholders start from an open-ended bottom-up approach which is tailored to the actual life situations of young people and their individual differences and consider more interpersonal and critical conceptualisations of ‘development’

Updated European Heart Rhythm Association practical guide on the use of non-vitamin-K antagonist anticoagulants in patients with non-valvular atrial fibrillation: Executive summary

In 2013, the European Heart Rhythm Association (EHRA) published a Practical Guide on the use of non-VKA oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) (Heidbuchel H, Verhamme P, Alings M, Antz M, Hacke W, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P, European Heart Rhythm A. European Heart Rhythm Association Practical Guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation. Europace 2013;15:625-651; Heidbuchel H, Verhamme P, Alings M, Antz M, Hacke W, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P. EHRA practical guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation: executive summary. Eur Heart J 2013;34:2094-2106). The document received widespread interest, not only from cardiologists but also from neurologists, geriatricians, and general practitioners, as became evident from the distribution of > 350 000 copies of its pocket version (the EHRA Key Message Booklet) world-wide. Since 2013, numerous new studies have appeared on different aspects of NOAC therapy in AF patients. Therefore, EHRA updated the Practical Guide, including new information but also providing balanced guiding in the many areas where prospective data are still lacking. The outline of the original guide that addressed 15 clinical scenarios has been preserved, but all chapters have been rewritten. Main changes in the Update comprise a discussion on the definition of 'non-valvular AF' and eligibility for NOAC therapy, inclusion of finalized information on the recently approved edoxaban, tailored dosing information dependent on concomitant drugs, and/or clinical characteristics, an expanded chapter on neurologic scenarios (ischaemic stroke or intracranial haemorrhage under NOAC), an updated anticoagulation card and more specifics on start-up and follow-up issues. There are also many new flow charts, like on appropriate switching between anticoagulants (VKA to NOAC or vice versa), default scenarios for acute management of coronary interventions, step-down schemes for longterm combined antiplatelet-anticoagulant management in coronary heart disease, management of bleeding, and cardioversion under NOAC therapy. The Updated Guide is available in full in EP Europace (Heidbuchel H, Verhamme P, Alings M, Antz M, Diener HC, HackeW, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P, Advisors. Updated European Heart Rhythm Association Practical Guide on the use of non-vitamin K antagonist anticoagulants in patients with non-valvular atrial fibrillation.

How to perform Contrast-Enhanced Ultrasound (CEUS)

"How to perform contrast-enhanced ultrasound (CEUS)" provides general advice on the use of ultrasound contrast agents (UCAs) for clinical decision-making and reviews technical parameters for optimal CEUS performance. CEUS techniques vary between centers, therefore, experts from EFSUMB, WFUMB and from the CEUS LI-RADS working group created a discussion forum to standardize the CEUS examination technique according to published evidence and best personal experience. The goal is to standardise the use and administration of UCAs to facilitate correct diagnoses and ultimately to improve the management and outcomes of patients

A roadmap to improve the quality of atrial fibrillation management:proceedings from the fifth Atrial Fibrillation Network/European Heart Rhythm Association consensus conference

At least 30 million people worldwide carry a diagnosis of atrial fibrillation (AF), and many more suffer from undiagnosed, subclinical, or 'silent' AF. Atrial fibrillation-related cardiovascular mortality and morbidity, including cardiovascular deaths, heart failure, stroke, and hospitalizations, remain unacceptably high, even when evidence-based therapies such as anticoagulation and rate control are used. Furthermore, it is still necessary to define how best to prevent AF, largely due to a lack of clinical measures that would allow identification of treatable causes of AF in any given patient. Hence, there are important unmet clinical and research needs in the evaluation and management of AF patients. The ensuing needs and opportunities for improving the quality of AF care were discussed during the fifth Atrial Fibrillation Network/European Heart Rhythm Association consensus conference in Nice, France, on 22 and 23 January 2015. Here, we report the outcome of this conference, with a focus on (i) learning from our 'neighbours' to improve AF care, (ii) patient-centred approaches to AF management, (iii) structured care of AF patients, (iv) improving the quality of AF treatment, and (v) personalization of AF management. This report ends with a list of priorities for research in AF patients
