Les publications des experts médicaux : l’exemple de l’anesthésie-réanimation

Forensic expertise becomes dominant in our society. Several reports questioned the competence of medical experts. We analysed the scientific competence of the 136 experts in Anaesthesia, Intensive Care and Emergency Medicine from senior courts in France. For that purpose, we made the choice of the H-Index and the number of scientific publications as markers of quality, using Google Scholar and PubMed databases. Thirty-five percent of experts have an H-Index equal to zero and 27 % never published. Out of the 104 experts who published at least one scientific article, 27 (26 %) did not publish for at least 10 years. The present study illustrates the great heterogeneity of the medical expert population regarding our criterions of judgement. This questions the selection and the operating mode of legal experts. There is a major difference with the selection process performed by the French Conciliation and Compensation Commissions. We propose that the official scholarly societies should be consulted during the appointment process.     

Safety of autonomous vehicles: what are the insights from experienced industry professionals?

Many drivers support the push towards the automation of transportation. Technology and automotive companies, the general public, and governments are all seen as the main groups pushing the automation revolution forward. The key to this revolution's success will rest with the perception of the professionals in the field as their perception will affect the way that Autonomous Vehicles (AVs) are adopted. This study surveyed 185 experienced industry professionals to gather their comments and opinions on AVs' purported safety benefits and drawbacks. The results in this paper illustrate that the ‘incorrect understanding of the surrounding objects by AVs’ could be the most significant technical concern and may lead to accidents. Some professionals had concerns about trusting the AVs’ safe operation without steering wheels, while some others believed that there is a chance that having steering wheels may increase safety concerns. The findings also suggest that while AVs might reduce the number of accidents, this may not necessarily be the case for the severity of any accidents. The severity may remain unchanged or even increase as a result of the adoption of AVs. This paper's results show that the majority of the professionals consulted agreed that AVs have the potential to increase road safety significantly. However, the consensus was that more research and testing is needed in this field.     

Responsabilités de l’expert judiciaire médical : des exigences déontologiques renforcées pour une activité accessoire

Medical doctor, forensic expert. Behind the duality of this role lie several professional obligations and responsibilities that must always be borne in mind by those who make a contribution to justice in providing their skills and professional knowledge. In reality, taking a moment to reflect on the ethical duties of the Forensic Medical Expert involves realizing that today, regulations and jurisprudence are seldom a requirement in a profession that performs an activity which may be ancillary but which is nonetheless essential in revealing the truth and therefore working towards Justice. Said person passes protean responsibilities on to health professionals for those who, paradoxically and statutorily, only occasionally work with the justice system. As such, from a civil, criminal and disciplinary perspective, a person skilled in the art is responsible for faults committed under the control of both the justice system and their peers in terms of their medical and expert activities. Given that the ancillary activity adds a great deal to the main role, this study raises the question of the ambiguity of a status that would benefit from official recognition as a regulated legal profession.     

The developmental activities engaged in by elite youth soccer players who progressed to professional status compared to those who did not

Objectives

We examined differences in the development pathways of elite youth soccer players in England who progressed to professional status in adulthood compared to those who did not.

Design

Comparative research design.

Method

Participants were elite youth soccer players (n = 32, 15 years of age). They completed the Participation History Questionnaire (PHQ; Ford, Low, McRobert, & Williams, 2010) under supervision.

Results

The participation history profiles of professional players followed the early engagement pathway in which they engaged in significantly more soccer play and practice compared to elite youth players who did not become professional, supporting previous work (e.g., Ford, Ward, Hodges, & Williams, 2009). The two groups of players engaged in four other sports, suggesting greater diversification than previously reported for soccer players, but less than that found in studies of team sport athletes in Australia and North America.

Conclusions

Professional soccer players in England follow an early engagement pathway during childhood and early adolescence.     

The contribution of memory to differences in situation awareness in expert and non-expert drivers

Situation awareness (SA) is knowing what is going on in the environment: identifying objects, understanding how they interact and predicting future events. It is important in the context of driving as it is related to hazard perception. Driving-related SA may help explain expert drivers’ superior driving skill, but it is important to understand whether this is because expert drivers have better memory for driving-related tasks, whether superior memory performance is task specific, and the degree to which any effect is attributable to experience vs. expertise. On-road paramedics were compared with non-expert drivers. The participants engaged in an SA driving task where they were required to describe a vide taped driving situation after the screen cut to black. We measured their SA, memory and demographic driving variables. The starting SA of World, Action and Schema was re-developed to better reflect driving SA, into World, Action, Other-Agent Action, Projection, and Rationale. Driving expertise predicted each category of SA, except the Action category, independently of other experience variables. Similarly, expertise also predicted SA categories independently of any of the memory tasks. We concluded that expert drivers have better driving-SA than non-expert drivers and this is not due to better memory for driving tasks, or ‘time-on-road’. This finding is important in driver training because if we can harness the SA skills that expert drivers demonstrate, we could potentially implement them in better driver training programs.     

The Stammering Information Programme: a Delphi study

Purpose

To find out what information children, parents and education staff feel would be important to know to support a child who stutters in the educational environment, in order to develop appropriate resources.

Method

A Delphi study was carried out to seek the opinions of experts about the information to include. A structured six stage process was completed in order to gain consensus within four expert panels: children who stutter (CWS) aged 7-11 (n = 25); young people who stutter aged 12-18 (n = 27); parents of children and young people who stutter aged 2-18 (n = 67); and members of the education workforce (n = 35).

Results

In response to the questions, 538 statements were generated across the four expert panels, categorised and reduced to 276. Of the 154 rating questionnaires sent out, 99 were returned (64.2% response rate). The top 32 statements, which were those most highly rated and with the greatest consensus, were retained to inform the resources.

Conclusions

This study demonstrates the value of including service users when devising materials aimed for the benefit of CWS. The methodology employed ensured that ideas, perceptions and needs were representative of a range of people who experience stuttering from different perspectives. The results indicated that each expert panel had different priorities of what should be included. The resulting resources may therefore be considered to have high content validity and would be predicted to meet the needs of those who require them.Educational Objectives: The reader will be able to (1) define the Delphi Approach (2) discuss the development of a user led resource for raising awareness about stuttering.     

Experts,Novices, and the St. Petersburg paradox: Is one solution enough?

Although the controversy over the correct solution to the St. Petersburg paradox continues in the decision making literature, few of the solutions have been empirically evaluated. Via the development of alternative versions of the St. Petersburg game, we were able to empirically test some of these solutions. Experts and novices behaved in accordance with Treisman's expectation heuristic when bidding for the right to play the various versions of the St. Petersburg game. When subjects were asked their preferences among the game versions. novices continued to behave in accordance with the expectation heuristic but a plurality of experts seemed to follow another strategy. This preference reversal and its implications and possible causes are thoroughly discussed. An alternative theory which mimicks the expectation heuristic is considered, and generalizations of the expectation heuristic and the St. Petersburg Paradox for z-sided 'coins' (where z is any integer greater than or equal to 2) are presented. It appears that no one solution is yet rich enough for the St. Petersburg paradox.     

Learning in the visual association of novice and expert designers

Designers are adept at determining similarities between previously seen objects and new creations using visual association. However, extant research on the visual association of designers and the differences between expert and novice designers when they engage in the visual association task are scant. Using electroencephalography (EEG), this study attempted to narrow this research gap. Sixteen healthy designers—eight experts and eight novices—were recruited, and asked to perform visual association while EEG signals were acquired, subsequently analysed using independent component analysis. The results indicated that strong connectivity was observed among the prefrontal, frontal, and cingulate cortices, and the default mode network. The experts used both hemispheres and executive functions to support their association tasks, whereas the novices mainly used their right hemisphere and memory retrieval functions. The visual association of experts appeared to be more goal-directed than that of the novices. Accordingly, designing and implementing authentic and goal-directed activities for improving the executive functions of the prefrontal cortex and default mode network are critical for design educators and creativity researchers.     

Embodiment of motor skills when observing expert and novice athletes

If people are shown a dynamic movie of an action such as kicking a soccer ball or hitting a tennis ball, they will respond to it faster if it requires the same effector. This standard congruency effect was reported to reverse when participants viewed static images of famous athletes not actually performing an action. It was suggested that the congruent response was inhibited because of a social contrast effect, based on an implied action, whereby responders viewed themselves as comparatively worse than the professional athlete. The present study recorded hand and foot responses when identifying static images of both famous and novice athletes in soccer and tennis. The action was either explicit or implied. In Experiment 1, a standard congruency effect was found for all images. In Experiment 2, when a response was based on the identity of the athlete rather than their expertise, the standard congruency effect was enhanced for images of novice athletes, but was eliminated for experts, suggesting a social contrast effect. Our study is the first to show that embodiment effects can be seen for implied and explicit action images of both novices and experts, and that static images are capable of eliciting priming effects associated with sport-relevant effector pairings.     

Becoming an expert in the musical domain: It takes more than just practice

Previous research has supported the theory that acquisition of expertise in any domain is possible for healthy individuals with sufficient deliberate practice, but such an extreme environmental position brings the existence of innate talent into question. The present study investigates the effects of both environmental factors and talent on expert performance in both high school and conservatory-level musicians. Audition scores and accumulated practice time were recorded, and correlated with scores on Gordon's Advanced Measures of Music Audiation and Raven's Progressive Matrices. Higher-level musicians report significantly higher mean levels on innate characteristics such as general intelligence and music audiation, in addition to higher levels of accumulated practice time. These factors together accounted for more of the variance in music performance than practice alone. A multi-factor view is thus shown to be the best explanation for the acquisition of musical expertise.     

Impact de la Loi no 2019-222 du 23 mars 2019 de programmation 2018–2022 et de réforme pour la justice sur l’office du médecin légiste

The new provisions of the article 60 of the French Code of Criminal Procedure now authorize the medical examiners to seal the samples taken during an autopsy or a medical examination. The result will be a new organization of the work of forensic doctors that the 2010s reform did not integrate. In addition, the presence of judicial police officers during the autopsies will probably have to be rethought. Moreover, the article 163 of the same code has not been amended, giving more competence to qualified persons than to experts appointed by an investigating judge.     

Temporal perception in closed-skill sports: An experimental study on expert swimmers and runners

The cognitive benefits of closed-skill sports practice have so far been scantily investigated. Here, we thus focused on the potential impact of swimming and running - two sports that highly rely on a precise control of timing - on time processing. To investigate the impact of these closed-skill sports on time perception and estimation, three groups of participants (for a total of eighty-four young adults) took part in the present study: expert swimmers, expert runners, and non-athletes. The ability to process temporal information in the milliseconds and seconds range was assessed through a time reproduction and a finger-tapping tasks, while a motor imagery paradigm was adopted to assess temporal estimation of sport performance in a wider interval range. We also employed the Vividness of Movement Imagery Questionnaire to assess the individual's ability of motor imagery. Results showed that closed-skill sports, specifically time-related disciplines, enhance motor imagery and time perception abilities. Swimmers were more accurate and consistent in perceiving time when compared to runners, probably thanks to the sensory muffled environment that leads these athletes to be more focused on the perception of their internal rhythm.     

The coupling between gaze behavior and opponent kinematics during anticipation of badminton shots

PurposeWe examined links between the kinematics of an opponent’s actions and the visual search behaviors of badminton players responding to those actions.MethodA kinematic analysis of international standard badminton players (n = 4) was undertaken as they completed a range of serves. Video of these players serving was used to create a life-size temporal occlusion test to measure anticipation responses. Expert (n = 8) and novice (n = 8) badminton players anticipated serve location while wearing an eye movement registration system.ResultsDuring the execution phase of the opponent’s movement, the kinematic analysis showed between-shot differences in distance traveled and peak acceleration at the shoulder, elbow, wrist and racket. Experts were more accurate at responding to the serves compared to novice players. Expert players fixated on the kinematic locations that were most discriminating between serve types more frequently and for a longer duration compared to novice players. Moreover, players were generally more accurate at responding to serves when they fixated vision upon the discriminating arm and racket kinematics.ConclusionsFindings extend previous literature by providing empirical evidence that expert athletes’ visual search behaviors and anticipatory responses are inextricably linked to the opponent action being observed.     

A learning system for adjustment processes based on human sensory perceptions

Creating, designing and adjusting products are essential decision processes underlying creative industries, such as painting, perfume, food and beverage industries. These processes require the participation and continuous supervision of professionals with highly-developed expert sensory abilities. Training of these experts is very complex due to the difficulty of transmitting intuitive knowledge obtained from perception. A new methodology for capturing this sensory expert knowledge that relies on a machine learning tool, previously trained with ‘state-action’ type patterns, jointly with an actions generator module, is proposed in this work. The method is based on a closed loop architecture together with the decomposition of complex sensory knowledge into basic elements capable of being handled by standard machine learning systems. A real case application to color-adjustment in the automotive paint manufacturing industry is presented showing the potential benefits of the method.     

An elicitation method for multiple linear regression models

This paper describes a method of quantifying subjective opinion about a normal linear regression model. Opinion about the regression coefficients and experimental error is elicited and modeled by a multivariate probability distribution (a Bayesian conjugate prior distribution). The distribution model is richly parameterized and various assessment tasks are used to estimate its parameters. These tasks include the revision of opinion in the light of hypothetical data, the assessment of credible intervals, and a task commonly performed in cue-weighting experiments. A new assessment task is also introduced. In addition, implementation of the method in an interactive computer program is described and the method is illustrated with a practical example.     

专家与新手教师内隐与外显学习的比较

教师作为典型的知识密集、技术密集的群体,其隐性知识也自然比较集中和典型,而专长研究可以有效地揭示教师的知识获取特点和学习规律。然而,以往的专长研究往往通过测量专家教师和新手教师在某方面的外显行为或外显知识的差异了解教师的知识结构和行为特点,这种做法由于忽略了教师的内隐学习和隐性知识,因此难以有效地揭示专家教师与新手教师在知识和能力结构上的真实差异。本研究借鉴认知心理学对专长的研究方式（即专家--新手比较）,运用经典的序列反应时任务（SRT）调整后的范式,采用带颜色边框的同一个学生的四种真实课堂表情图片作为刺激材料,以表情作为内隐学习的维度,以颜色作为外显学习的维度,对61名专家教师与88名新手教师在内隐/外显序列学习上的差异进行了比较研究。结果发现：（1）专家和新手教师被试群体均能够习得内隐/外显序列规则;（2）专家教师与新手教师在内隐学习上存在显著差异,专家教师内隐学习效果要优于新手教师;（2）专家教师与新手教师在外显学习维度上差异并不显著。结论：专家教师与新手教师有着近乎相当的外显学习能力和外显知识水平,但专家教师的内隐学习能力和隐性知识水平要显著高于新手教师。     

Destructiveness, atrocities and healing: epistemological and clinical reflections

In this paper, destructiveness is approached as a multi-dimensional phenomenon where the mental health perspective addresses only one of these dimensions. An attempt is made to locate this phenomenon in the context of epistemological and societal considerations. Critical of mono-dimensional explanations based on causal-reductive epistemology, the paper instead proposes the idea of an 'ecology of destructiveness', according to which mental health professionals cannot possibly continue to assume the role of detached observers. The ordinariness and archetypal fascination of destructiveness are discussed as preventing the psychologizing and pathologizing of it. In addition, it is suggested that 'destructiveness may be a tragic facet of the human condition', without this implying any justification of it. Based on my work with a group of Bosnian ex-camp prisoners, some basic principles of how one can work with survivors of atrocities are derived and discussed. A central feature of this work is the attempt to create an appropriate therapeutic context within which a 'therapeutic presence' and 'therapeutic witnessing' can be developed. Finally, the relevance of Jungian insights to this kind of work is reviewed and the emergence of new types of defences of the self is identified.     

Cognitive mediation of putting: Use of a think-aloud measure and implications for studies of golf-putting in the laboratory

ObjectivesWhereas accounts of skilled performance based on automaticity (Beilock & Carr, 2001; Fitts & Posner, 1967) emphasize reduced cognitive involvement in advanced skill, other accounts propose that skilled performance relies on increased cognitive control (Ericsson & Kintsch, 1995). The objective of this study was to test predictions differentiating the automaticity and cognitive control accounts by assessing thinking during golf putting.DesignThe cognitive processes of less-skilled and more-skilled golfers were examined during putting using concurrent, think-aloud verbal reports. The design included putting conditions that differed in complexity and thus the need to adapt the putt to the particular conditions.MethodPutting complexity was manipulated via changes to putt length and perceived stress during putting. Putts were executed from two starting locations (i.e., the same starting location as the previous putt or a new starting location).ResultsThe analysis showed that, during putting: more thoughts were verbalized overall by more-skilled golfers than less-skilled golfers; both groups verbalized more thoughts overall during higher-complexity putts (i.e., longer distance putts, and putts under higher stress when executed from a new starting location) than lower-complexity putts; and the two groups did not differ significantly in the number of thoughts related to motor mechanics.ConclusionsThe results of this study provide support for a cognitive control account of skilled performance and suggest that the path to skilled performance involves the acquisition of more refined higher-level cognitive representations mediating planning and analysis.
