    Global warming has become in few years a prominent problem which requires the implementation of a world governance to be solved. However, the share of human activities in the global warming phenomenon and the actions susceptible to mitigate the greenhouse gases emission generate scientifical, political and legal conflicts at the same time. Assessing the taking into account of climate change by international institutions raises several questions. By what process a true fact can become established at the world scale? Are experts free or constrain by procedure rules? How to regulate the worldwide carbon trade? Is the governance requirement foreseen in international systems respected by decision making practices? How to explain experts' omnipresence in the observance mechanisms of climate change treaties? Is their influence determining, at the international and internal scale, in the elaboration of a climate law? These questions, analyzed by researchers in law and political science, are indissociable of method stakes with an inter-disciplinary horizon. This book, result of a collective work, is not limited to a description of standards and actors' practices in force. Its ambition is to apprehend law, science and politics in their interactions. Climate change is an appropriate topic to think about the links between the different scientific disciplines. The book concludes with a prospective about the contribution of laws analysis to expertise which involves the dogmatic, realistic and epistemologic aspects. (J.S.)

    The present document corresponds to the third and last phase of the global critical analysis of the ten-year environmental assessment. It has for objective to evaluate the knowledge on the conditions of reuse, in the public area, of deads coming from the sites of Limousin and to propose an exploratory analysis of conceivable actions to complete this knowledge in order to better identify the sectors and, or, the potentially risk uses. At this day, the knowledge on the transfer of deads and their use in the public field rests on the data recorded in a register implemented by Areva Nc from 1984. According to the transfers anterior to 1984, the situation of knowledge especially about the places of destination and purpose are poor. The analysis of Areva NC data allowed to I.R.S.N. to identify the areas of improvement of knowledge. The first one consists in achieving information concerning deads occurring before 1984. the second one aims to check that every use of deads in the 1984-1995 period are compatible with the exposure levels.

  7. Developing English Communication Expertise for Engineers in the Global Age

    Science.gov (United States)

    Ono, Yoshimasa A.; Morimura, Kumiko

    This paper discusses contents and results of a new graduate course “English for Engineers and Scientists” given at School of Engineering, The University of Tokyo. This course is a new attempt to develop English communication expertise for engineering graduate students: how to write technical papers and how to make technical presentations in English. For these purposes, differences in the writing styles and in the sentence structures of English and Japanese are stressed: conclusions come first in English versus conclusions come last in Japanese; the three-step style of introduction, body, and conclusion in English versus the four-step style of ki-sho-ten-ketsu in Japanese. In addition, proper styles of technical papers (rhetoric) and related grammatical points are discussed. Technical presentation course consists of four-week lecture and seven-week practice session. In the lecture, essential points of technical presentations in English are discussed in detail, and in the practice session students‧ presentation skills are improved through guidance and instructions given by native-speaker moderators. The class evaluation results show that most students have obtained necessary skills of technical presentation, indicating that the combined course of lecture and practice session is essential for training students to make better technical presentations in English.

  8. CONTROLE DU RISQUE ET EXPERTISE : France : la précaution entre expertise et débat public Le cas des plantes transgéniques

    2000-07-01

    Full Text Available Depuis 1996, la commercialisation des premières plantes transgéniques s’est accompagnée d’un large débat en France (et en Europe. La controverse qui s’est ainsi développée a été le théâtre d’un processus d’appropriation par des acteurs hétérogènes de questions qui avaient été jusqu’alors essentiellement traitées par un cercle restreint d’intervenants réunis autour de quelques instances officielles de contrôle, dont principalement la Commission du génie biomoléculaire (CGB chargée de délivrer des avis auprès des instances exécutives concernant la dissémination dans l’environnement des organismes génétiquement modifiés (OGM. Une partie des critiques émises a porté sur les évaluations qui ont conduit à autoriser ces mises sur le marché ainsi que sur le fonctionnement de la CGB. Le gouvernement français a tenté de traduire cette demande d’ouverture du processus de décision à travers l’invocation du principe de précaution. L’extension de l’espace des débats a ainsi contribué à replacer la question des risques liés aux plantes transgéniques dans une réflexion élargie aux modèles de développement agricole et à l’alimentation. La rupture ainsi amorcée avec un modèle linéaire de la décision offre l’opportunité d’explorer le rôle qu’y remplissent les experts et les évolutions que pourrait impulser l’application du principe de précaution. En effet, de plus en plus présentée comme un nouveau paradigme en termes de politique environnementale et sanitaire, la précaution impliquerait une modification des liens unissant l’expertise scientifique et la décision. Fondant l’intervention publique sur la prise en compte des indéterminations, on peut toutefois se demander dans quelle mesure l’instrumentalisation de ce principe est limitée par une culture scientifique du risque encore dominée par une appropriation linéaire et déterministe de l’incertitude ?

  12. Search Engines and Expertise about Global Issues: Well-defined Landscape or Undomesticated Wilderness?

    Science.gov (United States)

    Fry, J.; Virkar, S.; Schroeder, R.

    This chapter investigates the `winner-takes-all' hypothesis in relation to how academic researchers access online sources and resources. Some have argued that the Web provides access to a wider range of sources of information than offline resources. Others, such as Hindman et al. (2003), have shown that access to online resources is highly concentrated, particularly because of how Internet search engines are designed. With researchers increasingly using the Web and Internet search engines to disseminate and locate information and expertise, the question of whether the use of online resources enhances or diminishes the range of available sources of expertise is bound to become more pressing. To address this question four globally relevant knowledge domains were investigated using large-scale link analysis and a series of semi-structured interviews with UK-based academic researchers. We found there to be no uniform `winner-takes-all' effect in the use of online resources. Instead, there were different types of information gatekeepers for the four domains we examined and for the types of resources and sources that are sought. Particular characteristics of a knowledge domain's information environment appear to determine whether Google and other Internet search engines function as a facilitator in accessing expertise or as an influential gatekeeper.

    2016-11-03

    To investigate the effects of evaluator fatigue and level of expertise on the grading of preclinical tooth crown preparations, by global and analytical methods of evaluation. The study had a double-blind design. Two faculty members, each with more than 10 years of clinical and teaching experience, and two demonstrators with no teaching experience evaluated tooth preparations on maxillary central incisors and mandibular first molars. As a test of the effect of fatigue, preparations were globally (subjective grading) and analytically (criteria-based grading) graded on day 1 (after evaluators had been on duty continuously for 8 hours) and day 2 (in the morning after evaluators had sufficient sleep). Evaluators worked under the same circumstances and did not communicate with each other. The assigned textbooks were used to develop the criteria for grading (rubric) and the predefined exclusion criteria. Grades were recorded and statistically analyzed using statistical software. The paired-sample t-test and Mann-Whitney U test were used for multiple comparisons. Level of significance was set at p ˂ 0.05. An inconsistency in preclinical tooth preparation evaluation was found to exist by both global and analytical methods. Junior faculty tended to award higher grades than senior faculty did. Furthermore, higher grades were scored by the analytical method. More clinical and academic experience did not guarantee intra- and interexaminer reliability. Younger faculty appeared to tolerate fatigue better than older faculty. Likewise, global evaluation appeared to be more influenced by fatigue than was the analytical method. There were variations in grading, with no consistently preferred grading method. Evaluator performance after continuous 8-hour duty had no significant effect on preclinical tooth preparation evaluation. Level of expertise did not affect preclinical evaluation regardless of the grading method used. © 2016 by the American College of Prosthodontists.

    Building a sustainable earthquake monitoring system requires well-informed cooperation between commercial companies that manufacture components or deliver complete systems and the government or other agencies that will be responsible for operating them. Many nations or regions with significant earthquake hazard lack the financial, technical, and human resources to establish and sustain permanent observatory networks required to return the data needed for hazard mitigation. Government agencies may not be well- informed about the short-term and long-term challenges of managing technologically advanced monitoring systems, much less the details of how they are built and operated. On the relatively compressed time scale of disaster recovery efforts, it can be difficult to find a reliable, disinterested source of information, without which government agencies may be dependent on partial information. If system delivery fails to include sufficient development of indigenous expertise, the performance of local and regional networks may decline quickly, and even data collected during an early high-performance period may be degraded or lost. Drawing on unsurpassed educational capabilities of its members working in close cooperation with its facility staff, IRIS is well prepared to contribute to sustainability through a wide variety of training and service activities that further promote standards for network installation, data exchange protocols, and free and open access to data. Members of the Consortium and staff of its Core Programs together could write a guide on decisions about network design, installation and operation. The intended primary audience would be government officials seeking to understand system requirements, the acquisition and installation process, and the expertise needed operate a system. The guide would cover network design, procurement, set-up, data use and archiving. Chapters could include advice on network data processing, archiving data (including

    2007-10-11

    Patients are valuable sources of expertise for other patients in similar situations, but little is understood about the nature of this expertise. To address this knowledge gap, we investigated informational support as a mechanism for peers to help one another learn to cope with the breast cancer experience. We analyzed the types of problems discussed and recommendations offered by correspondents in three online breast cancer communities. Informational support was prevalent and directed towards problems in which correspondents were planning for future events or coping with emergent situations. Peers shared a wealth of patient expertise, including action strategies, recommended knowledge, suggested approaches, and information resources for dealing with problems. Our results highlight how peers are helping one another to learn. These findings bring insight to new support we could provide to patients for developing and sharing patient expertise, such as problem-based information organization and functionality for collaborative problem solving.

    The combination of government's significant involvement in science, science's significant effects on the public, and public ignorance (of both politics and science) raise important challenges for reconciling scientific expertise with democratic governance. Nevertheless, there have recently been a variety of encouraging efforts to make scientific activity more responsive to social values and to develop citizens' capacity to engage in more effective democratic governance of science. This essay introduces a special issue of the Kennedy Institute of Ethics Journal, "Science, Expertise, and Democracy," consisting of five papers that developed from the inaugural Three Rivers Philosophy conference held at the University of South Carolina in April 2011. The pieces range from a general analysis of the in-principle compatibility of scientific expertise and democracy to much more concrete studies of the intersection between scientific practices and democratic values in areas such as weight-of-evidence analysis, climate science, and studies of locally undesirable land uses.

    Full Text Available Theories of expertise based on the acquisition of chunk and templates suggest a differential geometric organization of perception between experts and novices. It is implied that expert representation is less anchored by spatial (Euclidean proximity and may instead be dictated by the intrinsic relation in the structure and grammar of the specific domain of expertise. Here we set out to examine this hypothesis. We used the domain of chess which has been widely used as a tool to study human expertise. We reasoned that the movement of an opponent piece to a specific square constitutes an external cue and the reaction of the player to this perturbation should reveal his internal representation of proximity. We hypothesized that novice players will tend to respond by moving a piece in closer squares than experts. Similarly, but now in terms of object representations, we hypothesized weak players will more likely focus on a specific piece and hence produce sequence of actions repeating movements of the same piece. We capitalized on a large corpus of data obtained from internet chess servers. Results showed that, relative to experts, weaker players tend to 1 produce consecutive moves in proximal board locations, 2 move more often the same piece and 3 reduce the number of remaining pieces more rapidly, most likely to decrease cognitive load and mental effort. These three principles might reflect the effect of expertise on human actions in complex setups.

    2016-01-01

    Holistic processing—the tendency to perceive objects as indecomposable wholes—has long been viewed as a process specific to faces or objects of expertise. Although current theories differ in what causes holistic processing, they share a fundamental constraint for its generalization: Nonface objects cannot elicit facelike holistic processing in the absence of expertise. Contrary to this prevailing view, here we show that line patterns with salient Gestalt information (i.e., connectedness, closure, and continuity between parts) can be processed as holistically as faces without any training. Moreover, weakening the saliency of Gestalt information in these patterns reduced holistic processing of them, which indicates that Gestalt information plays a crucial role in holistic processing. Therefore, holistic processing can be achieved not only via a top-down route based on expertise, but also via a bottom-up route relying merely on object-based information. The finding that facelike holistic processing can extend beyond the domains of faces and objects of expertise poses a challenge to current dominant theories. PMID:26674129

    The regional center of stereotaxic radiosurgery of the University hospital center of Toulouse is equipped since april 2006 of a Novalis accelerator (Brainlab) devoted to the intra-skull stereotaxic radiosurgery. In april 2007, during an intercomparison of dosimetry computer files coming from different sites, the Brainlab society finds an anomaly in the files. The analysis made by the society concludes to to the use of an inappropriate detector for the measurement of a dosimetry parameter during the initial calibration of the accelerator. following this error, 145 patients (on the 172 treated by the service in question) suffer the consequences of an overdose whom importance is variable according the cases. The I.R.S.N. in charge of an expertise about the protocols of calibration of micro-beams before and after the correction of the dysfunction, took up with the search of the technical causes of the dysfunction. This report presents successively: the documents base on which is founded the expertise; the material of dosimetry and quality control necessary to the initial calibration of the device and to its follow-up; the formula made at the accelerator commissioning; the calibration of micro-beams in the two configurations that allows the device (micro-multi-knives and conic collimator) and the definition of parameters of the software of treatment planning; the maintenance and quality control implemented in the frame of its clinical use.

    1999-10-29

    The VIRGO project for the detection of gravitational waves will first operate in a test configuration, known as the Central Area Interferometer (CITF). The subject of this thesis consists of a study for the global control of this interferometer. In particular, the problems of auto-alignment and acquisition of lock are addressed. First, an investigation of the CITF optical response to longitudinal and angular mirror movements is given. On the basis of this study, we show how the ratio of photodiode signals can be used to detect and control the dark fringe when the CITF is far from its operating point (locked state). Furthermore, we present the simulation results of a quadrant photodiode configuration capable of reconstructing the mirrors' tilts once the CITF is in a locked state. The performance of a control system for the auto-alignment is then given. A study on the mode-cleaner prototype MC30 is then introduced in order to comprehend the process of lock acquisition by a linear feedback system for two different finesse values: F {approx_equal}100 and F {approx_equal} 1600. We define a threshold velocity for the mirrors' relative motion below which acquisition of lock is possible. A phenomenon, referred to as ringing effect, was observed and examined on the MC30 prototype in high finesse. The results of numerical calculations allowed us to fit measurement and estimate from them the cavity finesse as well as the mirrors' relative velocity during the resonance crossing. An empirical formula is then presented capable of determine the relative velocity from the positions of the oscillations' minima and maxima. An algorithm to guide into lock the CITF is then presented, consisting of an iterative procedure of velocity reconstruction and pulse application. A numerical calculation simulated the algorithm, the mirrors' motion, the optical response and the ADCs' process. As a result, acquisition times of the order of one second were observed: an

    Rather than investigating the extent to which training can improve performance under experimental conditions ('what could be'), we ask about the origins of expertise as it exists in the world ('what is'). We used the twin method to investigate the genetic and environmental origins of exceptional performance in reading, a skill that is a major focus of educational training in the early school years. Selecting reading experts as the top 5% from a sample of 10,000 12-year-olds twins assessed on a battery of reading tests, three findings stand out. First, we found that genetic factors account for more than half of the difference in performance between expert and normal readers. Second, our results suggest that reading expertise is the quantitative extreme of the same genetic and environmental factors that affect reading performance for normal readers. Third, growing up in the same family and attending the same schools account for less than a fifth of the difference between expert and normal readers. We discuss implications and interpretations ('what is inherited is DNA sequence variation'; 'the abnormal is normal'). Finally, although there is no necessary relationship between 'what is' and 'what could be', the most far-reaching issues about the acquisition of expertise lie at the interface between them ('the nature of nurture: from a passive model of imposed environments to an active model of shaped experience').

    Family members are known to be highly influential in the development of sport expertise. To date, much of the research in this area has focused on parents, with less known about sibling influences on expertise. This investigation explored associations between sport expertise, sibling characteristics, and sibling participation in sport and physical activity. Athletes representing three skill levels provided details of sibling characteristics and participation in sport and physical activity via the Developmental History of Athletes Questionnaire. Elite athletes were more likely to be later-born children, while pre-elite and non-elite athletes were more likely to be first-born. Compared with siblings of non-elite athletes, siblings of elite athletes were more likely to have participated in regular physical activity and were more likely to have participated in sport at the pre-elite and elite levels. These results suggest siblings may play a key role in sport expertise development. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  9. Perceptual learning and human expertise

    Science.gov (United States)

    Kellman, Philip J.; Garrigan, Patrick

    2009-06-01

    We consider perceptual learning: experience-induced changes in the way perceivers extract information. Often neglected in scientific accounts of learning and in instruction, perceptual learning is a fundamental contributor to human expertise and is crucial in domains where humans show remarkable levels of attainment, such as language, chess, music, and mathematics. In Section 2, we give a brief history and discuss the relation of perceptual learning to other forms of learning. We consider in Section 3 several specific phenomena, illustrating the scope and characteristics of perceptual learning, including both discovery and fluency effects. We describe abstract perceptual learning, in which structural relationships are discovered and recognized in novel instances that do not share constituent elements or basic features. In Section 4, we consider primary concepts that have been used to explain and model perceptual learning, including receptive field change, selection, and relational recoding. In Section 5, we consider the scope of perceptual learning, contrasting recent research, focused on simple sensory discriminations, with earlier work that emphasized extraction of invariance from varied instances in more complex tasks. Contrary to some recent views, we argue that perceptual learning should not be confined to changes in early sensory analyzers. Phenomena at various levels, we suggest, can be unified by models that emphasize discovery and selection of relevant information. In a final section, we consider the potential role of perceptual learning in educational settings. Most instruction emphasizes facts and procedures that can be verbalized, whereas expertise depends heavily on implicit pattern recognition and selective extraction skills acquired through perceptual learning. We consider reasons why perceptual learning has not been systematically addressed in traditional instruction, and we describe recent successful efforts to create a technology of perceptual

It verifies the existence and dimensions of the global-local phenomenon by examining the impact of the recent international economic crisis on the core and ring administrative subdivisions of the coastal zone of the Rome metropolitan area from 2008 to 2010. In particular, it compares housing market trends with available statistics on tourism and migration to provide an indicator of the economic crisis. The results of the research show that to some extent, there is a connection between a drop in house prices and a decreased flow of human mobility.Cet article traite de la façon dont les problèmes causés par des changements globaux interfèrent avec les problèmes locaux dans les régions côtières. Il vérifie l’existence et la taille du phénomène local-global, en examinant l’impact de la récente crise économique mondiale sur le noyau et les franges des zones côtières de la région métropolitaine de Rome durant la période 2008-2010. En particulier, il compare l’évolution du marché immobilier avec les statistiques disponibles sur le tourisme et les migrations pour fournir un indicateur de la crise économique. Les résultats de la recherche montrent que dans une certaine mesure, il y a une relation entre une chute des prix des logements et un flux plus faible en termes de mobilité humaine.

  5. Expertise and the evolution of consciousness.

    Science.gov (United States)

    Rossano, Matt J

    2003-10-01

    This paper argues that expertise can be used as an indicator of consciousness in humans and other animals. The argument is based on the following observations: (1) expertise and skill acquisition require deliberate practice; and (2) the characteristics of deliberate practice such as performance evaluation against a more proficient model, retention of voluntary control over actions, self-monitoring, goal-setting, error-detection and correction, and the construction of hierarchically organized retrieval structures are outside of the currently understood bounds of unconscious processing. Thus, to the extent that evidence of expertise exists in an organism, evidence of conscious experience is also present. Two important implications arise from this conclusion: (1) evidence of expertise can be used as the basis for cross-species comparisons of consciousness; and (2) the evolution of human consciousness can be assessed using fossil evidence of skilled behavior as a measure of consciousness.

    Using a whole-body counter, the authors have studied {sup 59}Fe absorption and loss in 8 normal subjects and in 30 iron deficient patients. Results showed that whole-body counting provided an excellent and simple method for iron retention measurements, obviating many inaccuracies of previous technic. Normal absorption of radio iron with this procedure has ranged from 9 per cent to 20 per cent of the administered tracer in normal subjects, with a mean of 15 per cent. A significant increase in {sup 59}Fe absorption was noted in 21 iron-deficient patients in whom the retention ranged from 40 to 100 per cent. However, 3 iron-deficient patients were found to have low absorption, and their severe iron deficiency could be correlated with this defect in absorption. This method permits also the determination of the rate of iron excretion during the following months and therefore the study of the mechanism of some pathological loss. (authors) [French] L'utilisation de la methode de comptage humain global a permis aux auteurs d'etudier l'absorption et l'excretion du fer-59 chez 8 sujets temoins et 30 sujets hyposideremiques.

La valeur normale de l'absorption du fer chez les temoins est d'environ 15 pour cent de la dose ingeree. Ce chiffre est tres fortement augmente chez 21 sujets hyposideremiques, pouvant atteindre 100 pour cent de la dose ingeree. Par contre, pour 3 malades, cette absorption est si faible qu'elle suggere une carence par defaut d'absorption.

  14. Using Highlighting to Train Attentional Expertise.

    Science.gov (United States)

    Roads, Brett; Mozer, Michael C; Busey, Thomas A

    2016-01-01

    Acquiring expertise in complex visual tasks is time consuming. To facilitate the efficient training of novices on where to look in these tasks, we propose an attentional highlighting paradigm. Highlighting involves dynamically modulating the saliency of a visual image to guide attention along the fixation path of a domain expert who had previously viewed the same image. In Experiment 1, we trained naive subjects via attentional highlighting on a fingerprint-matching task. Before and after training, we asked subjects to freely inspect images containing pairs of prints and determine whether the prints matched. Fixation sequences were automatically scored for the degree of expertise exhibited using a Bayesian discriminative model of novice and expert gaze behavior. Highlighted training causes gaze behavior to become more expert-like not only on the trained images but also on transfer images, indicating generalization of learning. In Experiment 2, to control for the possibility that the increase in expertise is due to mere exposure, we trained subjects via highlighting of fixation sequences from novices, not experts, and observed no transition toward expertise. In Experiment 3, to determine the specificity of the training effect, we trained subjects with expert fixation sequences from images other than the one being viewed, which preserves coarse-scale statistics of expert gaze but provides no information about fine-grain features. Observing at least a partial transition toward expertise, we obtain only weak evidence that the highlighting procedure facilitates the learning of critical local features. We discuss possible improvements to the highlighting procedure.

     There is very little literature defining characteristics of expert endoscopists. It is hypothesised that previously undetermined human factors may correlate with high performance in screening colonoscopists. The aim of this study was to determine factors contributing towards expertise in screening colonoscopy.  A focus group was used to hypothesise skills considered to be relevant to high performance in colonoscopy. The skills were then ranked in order of importance by an independent group of screening colonoscopists for both diagnostic and therapeutic colonoscopy. Twenty screening colonoscopists subsequently participated in individual semi-structured interviews to explore participants' views of expertise and the factors contributing to it. Data extracted from the interview transcripts were used to identify the thematic framework associated with expertise. The 5 initial highest-ranked themes were low complication rates, high adenoma detection rates, interpersonal skills with staff, communication skills, and manner with patients. Interviewees considered technical skills (20/20), previous experience of colonoscopy (19/20), judgment/decision-making (18/20), communication (18/20), teamwork (15/20), resources (11/20) and leadership (8/20) to be the most important themes related to expertise.  Both technical and non-technical abilities are considered essential components of expertise by experienced colonoscopists. Further research into targeted interventions to improve the rate of acquisition of these skills in training endoscopists may be useful in improving performance.

    Full Text Available Olfactory expertise remains poorly understood, most likely because experts in odor, such as perfumers, sommeliers and oenologists, are much rarer than experts in other modalities, such as musicians or sportsmen. In this review, we address the specificities of odor expertise in both odor experts and in a priori untrained individuals who have undergone specific olfactory training in the frame of an experiment, such as repeated exposure to odors or associative learning. Until the 21st century, only the behavioral effects of olfactory training of untrained control individuals had been reported, revealing an improvement of olfactory performance in terms of sensitivity, discrimination, memory, and identification. Behavioral studies of odor experts have been scarce, with inconsistent or inconclusive results. Recently, the development of cerebral imaging techniques has enabled the identification of brain areas and neural networks involved in odor processing, revealing functional and structural modifications as a function of experience. The behavioral approach to odor expertise has also evolved. Researchers have particularly focused on odor mental imagery, which is characteristic of odor experts, because this ability is absent in the average person but is part of a perfumer’s professional practice. This review summarizes behavioral, functional, and structural findings on odor expertise. These data are compared with those obtained using animals subjected to prolonged olfactory exposure or to olfactory-enriched environments and are discussed in the context of functional and structural plasticity.

    Science.gov (United States)

    2012-01-01

    Background Football (soccer) is one of the most popular sports in the world, including Europe. It is associated with important betting activities. A common belief, widely spread among those who participate in gambling activities, is that knowledge and expertise on football lead to better prediction skills for match outcomes. If unfounded, however, this belief should be considered as a form of “illusion of control.” The aim of this study was to examine whether football experts are better than nonexperts at predicting football match scores. Methods Two hundred and fifty-eight persons took part in the study: 21.3% as football experts, 54.3% as laypersons (non-initiated to football), and 24.4% as football amateurs. They predicted the scores of the first 10 matches of the 2008 UEFA European Football Championship. Logistic regressions were carried out to assess the link between the accuracy of the forecasted scores and the expertise of the participants (expert, amateur, layperson), controlling for age and gender. Results The variables assessed did not predict the accuracy of scoring prognosis (R2 ranged from 1% to 6%). Conclusions Expertise, age, and gender did not appear to have an impact on the accuracy of the football match prognoses. Therefore, the belief that football expertise improves betting skills is no more than a cognitive distortion called the “illusion of control.” Gamblers may benefit from psychological interventions that target the illusion of control related to their believed links between betting skills and football expertise. Public health policies may need to consider the phenomenon in order to prevent problem gambling related to football betting. PMID:22578101

In Experiment 3, to determine the specificity of the training effect, we trained subjects with expert fixation sequences from images other than the one being viewed, which preserves coarse-scale statistics of expert gaze but provides no information about fine-grain features. Observing at least a partial transition toward expertise, we obtain only weak evidence that the highlighting procedure facilitates the learning of critical local features. We discuss possible improvements to the highlighting procedure.

    Full Text Available Abstract Background Football (soccer is one of the most popular sports in the world, including Europe. It is associated with important betting activities. A common belief, widely spread among those who participate in gambling activities, is that knowledge and expertise on football lead to better prediction skills for match outcomes. If unfounded, however, this belief should be considered as a form of “illusion of control.” The aim of this study was to examine whether football experts are better than nonexperts at predicting football match scores. Methods Two hundred and fifty-eight persons took part in the study: 21.3% as football experts, 54.3% as laypersons (non-initiated to football, and 24.4% as football amateurs. They predicted the scores of the first 10 matches of the 2008 UEFA European Football Championship. Logistic regressions were carried out to assess the link between the accuracy of the forecasted scores and the expertise of the participants (expert, amateur, layperson, controlling for age and gender. Results The variables assessed did not predict the accuracy of scoring prognosis (R2 ranged from 1% to 6%. Conclusions Expertise, age, and gender did not appear to have an impact on the accuracy of the football match prognoses. Therefore, the belief that football expertise improves betting skills is no more than a cognitive distortion called the “illusion of control.” Gamblers may benefit from psychological interventions that target the illusion of control related to their believed links between betting skills and football expertise. Public health policies may need to consider the phenomenon in order to prevent problem gambling related to football betting.

    Full Text Available Le concept d’héritage culturel, ou patrimoine immatériel, est appliqué avec succès à l’alimentation, surtout dans les domaines de la consommation soutenable et critique, de la production traditionnelle et organique et du développement local. Néanmoins, ce processus exige un certain niveau de standardisation de la nourriture et des images associées adressées au grand public. La réinvention de la nourriture peut engendrer des stratégies d’auto-redécouverte qui impliquent une nouvelle lecture des histoires locales et des paysages, ainsi que la ré-évaluation du patrimoine intangible, mais tout ceci ne se passe pas dans un vide historique et juridique. Au contraire, les technicités commerciales et logistiques de la production interagissent sous de nombreux aspects avec la réinvention de la nourriture comme héritage. Ce phénomène apparaît de façon évidente dans la région alpine de l’Italie du nord, selon plusieurs études ethnographiques récentes.This article, based mainly on ethnographic examples of the transformation of traditional Alpine cheese-making systems, argues that a certain amount of standardization of traditional food systems is required in order to offer local products on a wider market basis. Nevertheless, this introduces important changes in the whole socio-technical system that underlies typical products: from raw material to product marketing. This also implies momentous changes about the ways in which local foods are produced, distributed and consumed, as well as in the ways they are socially and symbolically appropriated. Such reinvention of food can further mobilize local strategies for re-valuing intangible patrimony: local histories, material culture and landscapes. This is a complex and interconnected process, as highlighted by ethnographic examples provided – both from my own fieldwork and from current ethnographic literature. When food is reinvented as heritage, historical, juridical and

    Bartlett, James C; Boggan, Amy L; Krawczyk, Daniel C

    2013-01-01

    A classic finding in research on human expertise and knowledge is that of enhanced memory for stimuli in a domain of expertise as compared to either stimuli outside that domain, or within-domain stimuli that have been degraded or distorted in some way. However, we do not understand how experts process degradation or distortion of stimuli within the expert domain (e.g., a face with the eyes, nose, and mouth in the wrong positions, or a chessboard with pieces placed randomly). Focusing on the domain of chess, we present new fMRI evidence that when experts view such distorted/within-domain stimuli, they engage an active search for structure-a kind of exploratory chunking-that involves a component of a prefrontal-parietal network linked to consciousness, attention and working memory.

    In general, humans have impressive recognition memory for previously viewed pictures. Many people spend years becoming experts in highly specialized image sets. For example, cytologists are experts at searching micrographs filled with potentially cancerous cells and radiologists are expert at searching mammograms for indications of cancer. Do these experts develop robust visual long-term memory for their domain of expertise? If so, is this expertise specific to the trained image class, or do such experts possess generally superior visual memory? We tested recognition memory of cytologists, radiologists, and controls with no medical experience for three visual stimulus classes: isolated objects, scenes, and mammograms or micrographs. Experts were better than control observers at recognizing images from their domain, but their memory for those images was not particularly good (D' ~ 1.0) and was much worse than memory for objects or scenes (D' > 2.0). Furthermore, experts were not better at recognizing scenes or isolated objects than control observers.

    The Global Partnership Against the Spread of Weapons and Materials of Mass Destruction was launched by the heads of state and government of the G8 at the G8 summit in Kananaskis in June 2002. Fourteen other countries have since joined this G8 initiative. The aim of this partnership is to 'prevent terrorists, or those who harbor them, from acquiring or developing nuclear, chemical radiological and biological weapons, missiles, and related materials, equipment and technology'. Within the framework of the Partnership, the participants have agreed to support cooperation projects, starting with Russia, to promote non-proliferation, disarmament, the fight against terrorism and nuclear safety. The destruction of chemical weapons, the dismantling of decommissioned nuclear submarines, the disposal of fissile materials and the employment of former weapons scientists are among the priority concerns expressed. Ukraine has also been a beneficiary of this partnership since 2004. The participants in this initiative have agreed to contribute up to 20 billion dollars (up to 750 million euros from France) to support these projects over a period of ten years from 2002. A group of experts from the G8 on the Global Partnership (the GPWG = Global Partnership Working Group) meets regularly and gives an account of the progress made with this initiative in its annual report to the G8. These annual reports are published at the G8 summits. This document is the 2004 to 2006 activity report of the G8 global partnership.

    2018-01-01

    Pedagogical Content Knowledge (PCK) was accepted by worldwide Educators that it is a ubiquitous word in the preparation of teachers in the past decade. This study uses Pedagogical Content Knowledge (PCK) framework as a lens for classifying the guidelines and expectations for categorizing expertise teachers. Therefore, the paper tries to clarify the relationship between competencies of Thai expertise teacher and PCK elements. To promote skillful Thai teachers by offering them academic titles, the Office of the Teacher Civil Service and Education Personal Commission were developed to provide guidelines and expectations for categorizing expertise teachers (OTEPC, 2009). This article focuses on the guideline criteria which are three areas of consideration. The first area of consideration is teacher's disciplines including virtues and professional conducts. The second area of consideration is teacher's knowledge and teaching ability. The last area of consider is teacher's performance. It seemed that the OTEPC guideline pay too much attention on the first area. However, there are some issues of PCK appearing on the OTEPC teacher competency. The paper will discuss some suggestions of fill up PCK in the OTEPC guideline. The paper may have implication for Thailand teacher education.

  8. Intuitive expertise in ICT graduate supervision

    Full Text Available Intuitive expertise in the application of advanced interdisciplinary facilitation is the subject of this personal reflection on the graduate supervisory style of Professor David Squires in computers in education. This single-case reflective study examines the characteristics of effective supervision observed during masters and doctoral supervision at King's College in the years 1990-9. Interdisciplinarity in ICT graduate studies particularly requires a fluency of supervisory expertise in enabling supervisees to combine multiple complex perspectives from a number of fields of knowledge. Intuitive combinatory aspects of supervision are highlighted in this reflection on the role carried out by an academic expert in facilitating student success. This is examined from a perspective incorporating affective as well as intellectual elements, informed by characteristics identified in professional sports and performing arts coaching/mentoring. Key characteristics comprising a model of intuitive expertise in ICT graduate supervision were outlined. The resultant portrait aims to complement existing literature on graduate supervision, with reference to the field of ICTI computers in education relating to student hypermedia composition.

    Effective teaching requires an understanding of both what (content knowledge) and how (process knowledge) to teach. While previous studies involving medical students have compared preceptors with greater or lesser content knowledge, it is unclear whether process expertise can compensate for deficient content expertise. Therefore, the objective of our study was to compare the effect of preceptors with process expertise to those with content expertise on medical students' learning outcomes in a structured small group environment. One hundred and fifty-one first year medical students were randomized to 11 groups for the small group component of the Cardiovascular-Respiratory course at the University of Calgary. Each group was then block randomized to one of three streams for the entire course: tutoring exclusively by physicians with content expertise (n = 5), tutoring exclusively by physicians with process expertise (n = 3), and tutoring by content experts for 11 sessions and process experts for 10 sessions (n = 3). After each of the 21 small group sessions, students evaluated their preceptors' teaching with a standardized instrument. Students' knowledge acquisition was assessed by an end-of-course multiple choice (EOC-MCQ) examination. Students rated the process experts significantly higher on each of the instrument's 15 items, including the overall rating. Students' mean score (±SD) on the EOC-MCQ exam was 76.1% (8.1) for groups taught by content experts, 78.2% (7.8) for the combination group and 79.5% (9.2) for process expert groups (p = 0.11). By linear regression student performance was higher if they had been taught by process experts (regression coefficient 2.7 [0.1, 5.4], p teach first year medical students within a structured small group environment; preceptors with process expertise result in at least equivalent, if not superior, student outcomes in this setting.

L'embouchure du fjord est situee ala rencontre d'un chenal profond et d'un seuil de 20m de profondeur qui limite les echanges d'eau entre le fjord et l'estuaire du Saint-Laurent. Cependant, les grandes amplitudes de maree a son embouchure ont le potentiel d'entrainer des eaux denses du Saint-Laurent a l'interieur du fjord renouvelant ainsi les eaux des differents bassins. Dans le but d' a voir une meilleure comprehension de la dynamique et de la saisonnalite des renouvellements dans le bassin interne, deux mouillages y ont ete deployes pour recolter les premieres donnees de courant, sur toute la colonne d' eau et sur plusieurs mois, ainsi que des observations de temperature et de salinite a differentes profondeurs. L'un de ces mouillages n' a malheureusement pas pu etre analyse en detail dfi a la complexite de ses resultats et au manque de temps. Des profils ont ete recoltes le long de section transversales (transects), couvrant plusieurs saisons et plusieurs annees, ce qui a contribue a une meilleure comprehension de la distribution spatiale des masses d'eau dans le fjord. Les resultats montrent que ladynamique du fjord est plus complexe que ce qui avait ete precedemment presente dans la litterature.

The possibilities to use dGPS (differential global positioning system for forest mapping are analyzed. The efficiency of dGPS in forest condition is linked to canopy interference, which intercepts signals sent by some of the satellites or reflect them (multipathing. Two types of equipment have been tested: a Trimble Svee Six coupled with a RDS differential receiver and a Trimble SK8 coupled with an OMNISTAR differential receiver. Recordings have been achieved according to two modes: static (recording on one spot during one minute and cinematic (moving continuously along the stand limits. Two types of forest canopy were compared: light canopy made of young poplar plantation with few obstacles in the vicinity, and closed canopy of mature spruce stand edged with other mature stand. Cinematic mode efficiency is higher than static one (mean errors are respectively 3.1 m and 9.1 m. In the same way positioning is more accurate for the stand with light canopy than for the other one (mean errors are respectively 2.9 m and 9.4 m. Difference between recording modes are probably due to multipathing effect that filtering algorithm integrated in the GPS receivers are not able to remove in static mode. The efficiency of differential signal reception is also different for the two stands: 1.3/ and 20.5/ of missing differential signal respectively in the light and dense canopy conditions.

Participants were Cuban students with high level of expertise in music or in visual arts and with the same level of general education and socio-economic background. We used a multi-feature Mismatch Negativity (MMN design with sequences of either syllables in Mandarin Chinese or harmonic sounds, both comprising deviants in pitch contour, duration and Voice Onset Time (VOT or equivalent that were either far from (Large deviants or close to (Small deviants the standard. For both Mandarin syllables and harmonic sounds, results were clear-cut in showing larger MMNs to pitch contour deviants in musicians than in visual artists. Results were less clear for duration and VOT deviants, possibly because of the specific characteristics of the stimuli. Results are interpreted as reflecting similar processing of pitch contour in speech and non-speech sounds. The implications of these results for understanding the influence of intense musical training from childhood to adulthood and of genetic predispositions for music on foreign language perception is discussed.

  17. How to attain expertise in clinical communication?

    Wouda, Jan C; van de Wiel, Harry B M

    2013-12-01

    Several factors complicate the attainment of expertise in clinical communication. Medical curricula and postgraduate training insufficiently provide the required learning conditions of deliberate practice to overcome these obstacles. In this paper we provide recommendations for learning objectives and teaching methods for the attainment of professional expertise in patient education. Firstly, we propose to use functional learning objectives derived from the goals and strategies of clinical communication. Secondly, we recommend using teaching and assessment methods which: (1) contain stimulating learning tasks with opportunities for immediate feedback, reflection and corrections, and (2) give ample opportunity for repetition, gradual refinements and practice in challenging situations. Video-on-the-job fits these requirements and can be used to improve the competency in patient education of residents and medical staff in clinical practice. However, video-on-the-job can only be successful if the working environment supports the teaching and learning of communication and if medical staff which supervises the residents, is motivated to improve their own communication and didactic skills.

    Full Text Available In sociolinguistic terms, certain aspects of academician Grot’s activity can be seen as language policy. Therefore a discussion of the new conflictological direction of sociolinguistics (along with status and corpus directions is of current importance. Its object is delinquent communicative situations: 1 speech crimes against non-proprietary rights of people and organizations (deffamation and libel, against societal and governmental rights to normal functioning (speech extremism; 2 discussions of mass media deontology violations. Its objectives are identification and resolution of conflicts in communication, as well as punishment and prevention of speech crimes. Within its framework, the decision of a court or a deontological authority is a direct act of language policy, whereas a linguistic expertise is its consecutive act and simultaneously its tool. A linguistic expertise as a procedure of search for an evidential base of a speech crime is performed in governmental and independent centers. This correlates with a governmental and public direction of speech policy, revealing their inherent contradictions. As an illustration the author uses a lawsuit on protection of honor and dignity of a «United Russia» party member V. Svirid versus a well-known political figure of the opposition field, A. Navalny, in which the court verdict didn't take into consideration the professional opinions of linguistical experts from a regional university.

    During the G8 summit at Kananaskis (Canada) in June 2002, G8 Leaders decided to launch the Global Partnership against the Spread of Weapons and Materials of Mass Destruction. Under this initiative, partners support specific cooperation projects to address non-proliferation, disarmament, counter-terrorism and nuclear safety issues. Since then, thirteen other donor countries have joined the initiative from which the Ukraine may also now benefit. France intends to make an effective contribution, up to 750 million euros, to the implementation of this initiative, giving priority to a genuine partnership between France and Russia covering projects in the nuclear, chemical and biological fields. France intends to be involved in the various fields identified at Kananaskis: in the nuclear field, it is participating in nuclear submarine dismantling actions and contributes to the improvement of nuclear safety and security. It also supports the program for the disposition of Russian weapons-grade plutonium designated as no longer required for defence purposes. France is also involved in the destruction of chemical weapons and intends to develop responses to bio-terrorist threats, while promoting reemployment of scientists. To optimise its action, France has committed itself to both multilateral and bilateral programs. In the multilateral framework, France contributes to: - the NDEP fund (Northern Dimension Environment Partnership) which will finance projects related to the dismantling of nuclear submarines and remediation of the sites concerned; - the MPDG (Multilateral Plutonium Disposition Group), whose objective is to enable the disposition of Russian weapons-grade plutonium designated as no longer required for defence purposes; - the construction of the new Chernobyl shelter in the Ukraine.

    ISBA-A-gs is an option of the CNRM land surface model ISBA which allows for the simulation of carbon exchanges between the terrestrial biosphere and the atmosphere. The model was implemented for the first time at the global scale as a stand-alone model. Several global simulations were performed to assess the sensitivity of the turbulent fluxes and Leaf Area Index to a doubling of the CO{sub 2} atmospheric concentration, and to the climate change simulated by the end of the 21. century. In addition, a new option of ISBA, referred to as ISBA-CC, was developed in order to simulate a more detailed ecosystem respiration by separating the autotrophic respiration and the heterotrophic respiration. The vegetation dynamics and the carbon fluxes were validated at a global scale using satellite datasets, and at a local scale using data from 26 sites of the FLUXNET network. All these results show that the model is sufficiently realistic to be coupled with a general circulation model, in order to account for interactions between the terrestrial biosphere, the atmosphere and the carbon cycle.

    High-performance computing (HPC) is one area where the DOE has developed extensive expertise and capability. However, this expertise currently is not properly shared with or used by the private sector to speed product development, enable industry to move rapidly into new areas, and improve product quality. Such use would lead to substantial competitive advantages in global markets and yield important economic returns for the United States. To stimulate the dissemination of DOE's HPC expertise, the Council for Chemical Research (CCR) and the DOE jointly held a workshop on this topic. Four important energy topic areas were chosen as the focus of the meeting: Biomass/Bioenergy, Catalytic Materials, Energy Storage, and Photovoltaics. Academic, industrial, and government experts in these topic areas participated in the workshop to identify industry needs, evaluate the current state of expertise, offer proposed actions and strategies, and forecast the expected benefits of implementing those strategies.

  7. Expertise in Everyday Nurse–Patient Conversations

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available A great deal of nursing activity is embedded in what is considered to be everyday conversation. These conversations are important to health professionals because communication can affect health outcomes, and they are important to patients who want to know they are being heard and cared for. How do nurses talk with patients and what are the features of effective communication in practice? In this exploratory study, two expert nurses recorded conversations with patients during domiciliary visits. Linguistic discourse analysis, informed by contextual knowledge of domiciliary nursing shows the nurses skillfully used small talk to support their clinical work. In their conversations, nurses elicit specific information, normalize unpleasant procedures, manage the flow of the interaction, and strengthen the therapeutic relationship. Small talk can be big talk in achieving nursing goals. Critically reflecting on recorded clinical interactions can be a useful method of professional development and a way of demonstrating nursing expertise.

    Full Text Available As I write this editorial, I am on an airplane, reflecting on the EBLIP6 conference, held June 27-30, 2011 in Salford, U.K. In my personal opinion, the conference was a great success. There were a wide variety of concurrent paper sessions from an international group of delegates, thought provoking keynotes, and just the right amount of social activity, including the main conference dinner at the Manchester United Football Club! This journal will have a Feature section in our next issue (December that highlights the conference, including keynote presentations, some of the papers that were presented, and commentaries from attendees about the conference itself. So for now, I’ll just offer my warmest congratulations to the organizers.As I left Salford and tried to reflect on what I had learned and discussed with others, there were many things that came to mind. Immediate things that stood out for me had to do with impact, reflection, and the complexity of decision making. The theme of EBLIP6 was “Valuing Knowledge and Expertise”. This is a somewhat controversial theme for an evidence based practice conference, where research evidence and its implementation are the focus, and expert opinion is not generally held in high regard. None of the keynote speakers’ presentations spoke directly to the theme, however several paper presentations did include some reference to the importance of professional knowledge.Expertise is a loaded word, filled with notions of snobbery and over-confidence, even close-mindedness. If anything, those involved with EBLIP remove themselves as far from the notion of “expert” as they can. But if we consider an expert to be someone who has built up a significant amount of professional knowledge (both through experience and research on a topic, then the EBLIP movement should not simply dismiss this notion of “expert”. Perhaps, we more appropriately should consider expert voices (knowledgeable, reasonable

  11. Unitizing worker expertise and maximizing the brain reward centers

    Martinez, Anthony Bert [Los Alamos National Laboratory

    2010-01-01

    People are experts when it comes to the work they do; unfortunately their expertise is not utilized as frequently as it could be. More opportunities need to be provided that allow people to participate in the design of their work including: accident investigations, job planning, and process improvements. Many employers use some form of job hazard analysis process to identify and document hazards and controls, but the front line worker is rarely involved. This presentation will show the core principles supporting employee involvement, provide examples where workers had brilliant ideas but no one listened, and provide examples where workers were given the opportunity to use their expertise to improve occupational safety. According to Abraham Maslow's Hierarch of Needs model, one essential human need is to be innovative and solve problems. Advances in brain science have proven, through functional magnetic resonance imaging (fMRI) studies, the brain reward pathway is activated when people are recognized for their intellectual contributions. As people contribute their expertise to improve occupational safety more frequently they will feel a sense of gratification. In addition, safety professionals will have more time to spend on strategic planning of emerging occupational safety issues. One effect of the current global recession is that SH&E professionals are asked to do more with less. Therefore, to be successful it is essential that SH&E professionals incorporate worker expertise in job planning. This will be illustrated in the presentation through an example where a worker had the answer to a difficult decision on appropriate personal protective equipment for a job but no one asked the worker for his idea during the job planning phase. Fortunately the worker was eventually consulted and his recommendation for the appropriate personal protective equipment for the job was implemented before work began. The goal of this presentation is to expand the awareness and

Les résultats de la fonction de production Cobb-Douglas prouvent que l'utilisation du compost est statistiquement significative pour expliquer la variation de rendement de la laitue et que le compost est l'intrant le plus productif. D'autres résultats montrent que le compost fournit la matière organique utile au sol et que les besoins d'irrigation en eau de la culture sont réduits grâce à l'utilisation du compost. Par conséquent, malgré le fait que l'application du compost demande une main-d'oeuvre beaucoup plus élevée, son utilisation est généralement bénéfique pour les agriculteurs vivant aux alentours de Yaoundé.

    Hardré, Patricia L; Nihira, Mikio; LeClaire, Edgar; Moen, Michael

    The aim of this study was to describe how professional expertise is defined and understood among gynecologic surgeons and what experiential factors contribute to that understanding. Semistructured interviews with 16 experts in Female Pelvic Medicine and Reconstructive Surgery were conducted to identify how expertise in their field is defined, recognized, and assessed. Independent thematic analysis of the interview transcripts was performed by each member of the research team and then distilled and synthesized into convergent themes. Experts described surgical expertise as difficult to define but with several dominant themes including knowledge, technical skills, clinical experience, adaptability, continuous learning, communication, and professional recognition. Expertise requires judgment in applying technical skills to meet each patient's specific needs. Experts described unique ways of seeing and thinking during surgery, characterized by spatial awareness of relevant anatomy, temporal awareness of future changes, and rapidly adaptive application of their skills enabling them to do difficult tasks with fluidity, making the tasks seem easy to observers. These expert surgeons acknowledged that achieving expertise requires hard work and maintaining expertise requires continuous learning, highlighted by challenge seeking to do the most difficult tasks in their field. They also noted the importance of effective communication of their knowledge to others, which contributes to their perception as experts by colleagues in the field. Surgical expertise is a complex phenomenon with several meaningful themes. Understanding the authentic nature of surgical expertise can be used to support the development of competencies and the effective mentoring of promising surgical trainees to achieve surgical expertise.

  16. The Automation-by-Expertise-by-Training Interaction.

    Science.gov (United States)

    Strauch, Barry

    2017-03-01

    I introduce the automation-by-expertise-by-training interaction in automated systems and discuss its influence on operator performance. Transportation accidents that, across a 30-year interval demonstrated identical automation-related operator errors, suggest a need to reexamine traditional views of automation. I review accident investigation reports, regulator studies, and literature on human computer interaction, expertise, and training and discuss how failing to attend to the interaction of automation, expertise level, and training has enabled operators to commit identical automation-related errors. Automated systems continue to provide capabilities exceeding operators' need for effective system operation and provide interfaces that can hinder, rather than enhance, operator automation-related situation awareness. Because of limitations in time and resources, training programs do not provide operators the expertise needed to effectively operate these automated systems, requiring them to obtain the expertise ad hoc during system operations. As a result, many do not acquire necessary automation-related system expertise. Integrating automation with expected operator expertise levels, and within training programs that provide operators the necessary automation expertise, can reduce opportunities for automation-related operator errors. Research to address the automation-by-expertise-by-training interaction is needed. However, such research must meet challenges inherent to examining realistic sociotechnical system automation features with representative samples of operators, perhaps by using observational and ethnographic research. Research in this domain should improve the integration of design and training and, it is hoped, enhance operator performance.

  18. Sherlock Holmes: an expert's view of expertise.

    Science.gov (United States)

    André, Didierjean; Fernand, Gobet

    2008-02-01

    In recent years, there has been an intense research effort to understand the cognitive processes and structures underlying expert behaviour. Work in different fields, including scientific domains, sports, games and mnemonics, has shown that there are vast differences in perceptual abilities between experts and novices, and that these differences may underpin other cognitive differences in learning, memory and problem solving. In this article, we evaluate the progress made in the last years through the eyes of an outstanding, albeit fictional, expert: Sherlock Holmes. We first use the Sherlock Holmes character to illustrate expert processes as described by current research and theories. In particular, the role of perception, as well as the nature and influence of expert knowledge, are all present in the description of Conan Doyle's hero. In the second part of the article, we discuss a number of issues that current research on expertise has barely addressed. These gaps include, for example, several forms of reasoning, the influence of emotions on cognition, and the effect of age on experts' knowledge and cognitive processes. Thus, although nearly 120-year-old, Conan Doyle's books show remarkable illustrations of expert behaviour, including the coverage of themes that have mostly been overlooked by current research.

  19. The appraisal rationalisation of real estate expertise

    Directory of Open Access Journals (Sweden)

    Marina Ciuna

    2013-12-01

    Full Text Available The Italian appraisal practice is characterized by valuations developed in subjective opinions formulated by the valuers, according to the experience and the competence rather than on the survey of the market data of comparable properties. This practice makes up for the lack of information on the real estate market and to the consequent absence of systematic collections of market data. This tradition is in the cadastral appraisal for the rural (1886 and urban properties (1939. The assessed income is appraised for a representative property and wide to all the other properties with arbitrary scores (pure number. The assessed value is derived from the income with fixed multipliers. The reform of the cadastral appraisals (2013 provides the employment of predetermined statistic functions rather than the automated valuation models applied in the mass appraisal. There are therefore ample spaces to rationalize the Italian valuations. For the market appraisal the process of rationalization is based on the comparison between the expertise and the market comparison approach. For the cadastral appraisal the process of rationalization is based on the statistic application to the fixed functions with the survey of a sample of market prices and the ratios study according to the valuation standards.

    In March 2010, the ITER operator delivered the facility safety file to the French "Autorité de Sûreté Nucléaire" (ASN) as part of its request for the creation decree, legally necessary before building works can begin on the site. The French "Institut de Radioprotection et de Sûreté Nucléaire" (IRSN), in support to the ASN, recently completed its expertise of the safety measures proposed for ITER, on the basis of this file and of additional technical documents from the operator. This paper presents the IRSN's main conclusions. In particular, they focus on the radioactive materials involved, the safety and radiation protection demonstration (suitability of risk management measures…), foreseeable accidents, building and safety important component design and, finally, wastes and effluents to be produced. This assessment was just the first legally-required step in on-going safety monitoring of the ITER project, which will include other complete regulatory re-evaluations.

    Hulle, M

    2007-07-01

    The primary objective of this project is to investigate the effects of global change on the biodiversity of aphid communities in Western Europe. Biodiversity has been examined at 3 levels: total number of species, phenology and reproductive strategy. Data were provided by EXAMINE, the European suction traps network which has been now operating for 35 years. 392 different species have been identified. At each location, total number of species has been regularly increasing, one additional species being caught every 1 or 2 years depending on location. This is due to introduced species but also to warming which favours rare species. No general trend of increasing density has been detected, but phenological earliness of almost all species (annual date of first appearance in suction traps) is strongly correlated with temperature and especially with mean daily temperature (during more or less long periods of time lying principally in February and March) or number of days below 0 C. Strong relationships between aphid phenology and environmental variables have been found and there is strong discrimination between species with different life cycle strategies, and between species feeding on herbs and trees, suggesting the possible value of trait-based groupings in predicting responses to environmental changes. These preliminary results suggest that 1) biodiversity has increased during the last decades; 2) there is a pool of species among which some of them reach a detectable density only during years where temperatures are high enough; 3) a set of newly introduced species succeed in settling being favoured by warming and 4) phenology of aphids is expected to advance and their abundance to increase with temperature, and the possible role of natural enemies to regulate abundant species is discussed.

    McHugh, Matthew D.; Lake, Eileen T.

    2010-01-01

    Clinical nursing expertise is central to quality patient care. Research on factors that contribute to expertise has focused largely on individual nurse characteristics to the exclusion of contextual factors. To address this, we examined effects of hospital contextual factors and individual nurse education and experience on clinical nursing expertise in a cross-sectional analysis of data from 8,611 registered nurses. In a generalized ordered logistic regression analysis, the composition of the hospital staff, particularly the proportion of nurses with at least a bachelor of science in nursing degree, was associated with significantly greater odds of a nurse reporting a more advanced expertise level. Our findings suggest that, controlling for individual characteristics, the hospital context significantly influences clinical nursing expertise. PMID:20645420

    Full Text Available Housing in Hungary has undergone significant changes since the years of political and economic transition. During the socialist decades the housing sector was controlled by the state, market forces were marginal or non-existent. Thus, one of the biggest changes in housing was the establishment of a western-type residential market after the regime change. The latest worldwide economic crisis has had a dramatic impact on the Hungarian housing market. The turnover of the Hungarian residential market has declined enormously in the past few years. Those families who financed their housing by foreign currency mortgages are facing the hardest situation. The Hungarian forint has significantly weakened against other currencies having resulted in a dramatic increase in foreign currency mortgage payments. First, the paper briefly reviews the literature on housing theories, then it outlines the most important milestones in the development of the Hungarian residential market. The next part of the paper introduces the most problematic issues and areas concerning housing in Hungary, and finally analyzes the effects and consequences of the present economic crisis.En Hongrie, le logement est confronté à d’importantes mutations depuis les années de transition politique et économique. Durant les décennies du socialisme, ce secteur se trouvait sous le contrôle de l’état et les forces du marché étaient marginales, voire inexistantes.

    In this paper we present an alternative perspective to physics expertise research. Using Lave and Wenger's theoretical perspective of Legitimate Peripheral Participation [4] as a guide to understanding expertise development, we redefine expertise from the perspective of physicists. We analyze data from an ethnographic, qualitative study of a physics research group and draw data from multiple sources to triangulate a definition of expert. Results show that a very critical part of becoming a physics expert in this physics research group is communicating one's scientific ideas through writing. Students perceive scientific writing as an important aspect of participating in the research group and it is a significant discussion point in the research meetings. Thus, it appears that learning to write a scientific paper is a process congruent to developing physics expertise.

    Full Text Available Interviews with both refugees and organizational staff in two nonprofit refugee resettlement organizations in the United States reveal the ways in which knowledge(s and expertise are crafted, threatened, and understood in refugee organizations. Refugee-participants described the need for knowledgeable communication, barriers to the communication of knowledge, and processes of negotiating whose expertise is involved. Organizational staff participants described the duty of communicating expert knowledge, the limits of knowledge as expertise, and alternative communications of expertise. These tensions surrounding “knowing” in refugee resettlement organizations highlights the need for a more complex theoretical understanding of the processes of knowing present in refugee resettlement. These tensions also suggest areas in which refugee resettlement agencies and other nonprofit staff can make on-the-ground changes to better facilitate refugee resettlement processes.

    Full Text Available The purpose of the present investigation was to analyse interviews of highly regarded Finnish magicians. Social network analysis (N=120 was used to identify Finland’s most highly regarded magicians (N=16. The selected participants’ careers in professional magic and various aspects of their professional conduct were examined by relying on semi-structured interviews. The results revealed that cultivation of professional level competence in magic usually requires an extensive period of time compared with other domains of expertise. Magic is a unique performing art and it differs from other professions focusing on deceiving the audience. A distinctive feature of magical expertise is that the process takes place entirely through informal training supported by communities of magical practitioners. Three interrelated aspects of magical activity were distinguished: magic tricks, performance, and audience. Although magic tricks constitute a central aspect of magic activity, the participants did not talk about their tricks extensively; this is in accordance with the secretive nature of magic culture.The interviews revealed that a core aspect of the magicians’ activity is performance in front of an audience that repeatedly validates competence cultivated through years of practice. The interviewees reported investing a great deal of effort in planning, orchestrating, and reflecting on their performances. Close interaction with the audience plays an important role in most interviewees’ activity. Many participants put a great deal of effort in developing novel magic tricks. It is common to borrow magic effects from fellow magicians and develop novel methods of implementation. Because magic tricks or programs are not copyrighted, many interviewees considered stealing an unacceptable and unethical aspect of magical activity. The interviewees highlighted the importance of personality and charisma in the successful pursuit of magic activity.

    Long, Chengjiang; Hua, Gang; Kapoor, Ashish

    2016-01-01

    We present a noise resilient probabilistic model for active learning of a Gaussian process classifier from crowds, i.e., a set of noisy labelers. It explicitly models both the overall label noise and the expertise level of each individual labeler with two levels of flip models. Expectation propagation is adopted for efficient approximate Bayesian inference of our probabilistic model for classification, based on which, a generalized EM algorithm is derived to estimate both the global label noise and the expertise of each individual labeler. The probabilistic nature of our model immediately allows the adoption of the prediction entropy for active selection of data samples to be labeled, and active selection of high quality labelers based on their estimated expertise to label the data. We apply the proposed model for four visual recognition tasks, i.e., object category recognition, multi-modal activity recognition, gender recognition, and fine-grained classification, on four datasets with real crowd-sourced labels from the Amazon Mechanical Turk. The experiments clearly demonstrate the efficacy of the proposed model. In addition, we extend the proposed model with the Predictive Active Set Selection Method to speed up the active learning system, whose efficacy is verified by conducting experiments on the first three datasets. The results show our extended model can not only preserve a higher accuracy, but also achieve a higher efficiency.

    Gélinas-Phaneuf, Nicholas; Del Maestro, Rolando F

    2013-10-01

    : The development of technical skills is a major goal of any neurosurgical training program. Residency programs in North America are focused on achieving an adequate level of training to produce technically competent surgeons. The training requirements and educational environments needed to produce expert surgeons are incompletely understood. This review explores the theoretical implications of training technical skills to expertise rather than competency in a complex field such as neurosurgery. First, the terms technical expertise and technical competency are defined. Definitions of these qualities are lacking in all surgical specialties. Second, the assessment of technical skills of neurosurgeons are investigated using an expert performance approach. This approach entails the design of tasks that can capture the level of expertise in a reproducible manner. One method to accomplish this involves the use of novel simulators with validated performance metrics. Third, the training of technical skills using simulation is studied in the optic of developing training curricula that would target the development of expertise rather than simple competency. Such curricula should include objective assessments of technical skills, appropriate feedback, and a distributed schedule of deliberate practice. Implementing a focus on the development of expertise rather than simple competency in surgical performance will lead to innovative developments in the field of neurosurgical education. Novel technologies, such as simulation, will play important roles in the training of future expert surgeons, and focused technical skills curricula with a sound theoretical basis should guide the development of all such programs.

    Predictive theories of action observation propose that we use our own motor system as a guide for anticipating and understanding other people's actions through the generation of context-based expectations. According to this view, people should be better in predicting and interpreting those actions that are present in their own motor repertoire compared to those that are not. We recorded high-density event-related potentials (ERPs: P300, N400 and Slow Wave, SW) and source estimation in 80 subjects separated by their level of expertise (experts, beginners and naïves) as they observed realistic videos of Tango steps with different degrees of execution correctness. We also performed path analysis to infer causal relationships between ongoing anticipatory brain activity, evoked semantic responses, expertise measures and behavioral performance. We found that anticipatory activity, with sources in a fronto-parieto-occipital network, early discriminated between groups according to their level of expertise. Furthermore, this early activity significantly predicted subsequent semantic integration indexed by semantic responses (N400 and SW, sourced in temporal and motor regions) which also predicted motor expertise. In addition, motor expertise was a good predictor of behavioral performance. Our results show that neural and temporal dynamics underlying contextual action anticipation and comprehension can be interpreted in terms of successive levels of contextual prediction that are significantly modulated by subject's prior experience.

    2006-03-01

    We explore how expertise is obtained in the domain of rugby refereeing. The research data are qualitative and are drawn from an 18 month period working in collaboration with the Rugby Football Union Elite Referee Unit. Adopting an ethnographic mode of enquiry, the study combined long-term participant observation with in-depth interviewing, indirect observations and the collection of artefacts including existing protocol, coach feedback forms and strategic reports. The diversity of methodologies allowed us to examine how expertise is developed across various domains of analysis, including the intrapersonal, interpersonal, group and social perspectives. Building on expertise studies in "deliberate practice", further prerequisites for expertise, at least in this domain and with these participants, incorporated "deliberate experience" and "transfer of skills". Additionally, a key issue in the findings concerns a shift from "descriptive" towards a "non-linear processes"-oriented model of development. We conclude by identifying opportunities and limitations associated with the adoption of ethnography as a method for studying expertise.

    The goal of the current study was to investigate the relationship between sport expertise and perceptual and cognitive skills, as measured by the component skills approach. We hypothesized that athletes would outperform non-athlete controls in a number of perceptual and cognitive domains and that sport expertise would minimize gender differences. A total of 154 individuals (87 professional volleyball players and 67 non-athlete controls) participated in the study. Participants performed a cognitive battery, which included tests of executive control, memory, and visuo-spatial attention. Athletes showed superior performance speed on three tasks (two executive control tasks and one visuo-spatial attentional processing task). In a subset of tasks, gender effects were observed mainly in the control group, supporting the notion that athletic experience can reduce traditional gender effects. The expertise effects obtained substantiate the view that laboratory tests of cognition may indeed enlighten the sport-cognition relationship.

  8. Defining a Profession: The Role of Knowledge and Expertise

    Directory of Open Access Journals (Sweden)

    Mike Saks

    2012-06-01

    Full Text Available The paper highlights the importance of resurrecting the debate about how to define a profession. The drive to define a profession is traced back to the taxonomic approach – encompassing the work of trait and functionalist writers – in which professions were seen as possessing unique and positive characteristics, including distinctive knowledge and expertise. A range of critical challenges to this approach are then considered, particularly as they relate to the role of knowledge and expertise in defining a profession, covering interactionism, Marxism, Foucauldianism and discourse analysis. However, the most effective challenge to the taxonomic approach is considered to be the neo-Weberian perspective based on a less broadly assumptive and more analytically useful definition of a profession centered on exclusionary closure. With reference to case studies, the relative merits of neo-Weberianism compared to taxonomic and other approaches are examined in relation to the role of knowledge and expertise and delineating professional boundaries.

    Full Text Available Systems for expertise location are either very expensive in terms of the costs of maintenance or they tend to become obsolete or incomplete during the time. This article presents a new approach to knowledge mapping/expertise location allowing reducing the costs of knowledge mapping by maintaining the accuracy of the knowledge map. The efficiency of the knowledge map is achieved by introducing the knowledge estimation measures analysing the dynamics of knowledge of company employees and their textual results of work. Finding an expert with most up-to date knowledge is supported by focusing publishing history analysis. The efficiency of proposed measures within various timeframes of publishing history is evaluated by evaluation method introduced within the article. The evaluation took place in the environment of a middle-sized software company allowing seeing directly a practical usability of the expertise location technique. The results form various implications deployment of knowledge map within the company.

    Full Text Available The five-year evaluation of the Global Fund to fight HIV/AIDS, TB and malaria (GFATM was carried out by a Consortium of several universities and institutions, led by a consulting firm based in Washington DC. The evaluation focused on three study areas: (i organizational efficiency and effectiveness of the Global Fund, (ii effectiveness of the Global Fund partner environment, (iii system effects of the Global Fund and impact of increased funding on the level of response to the three diseases. The findings can be summarized as follows: the Global Fund has been successful in mobilizing additional funding and attracting new players. However, the demand-driven model used for allocation of funding is poorly adapted to epidemiological profiles with regard to population, persons at highest risk, and number of persons affected by the disease. The partner environment of the Global Fund, involving UN technical partners and institutions cooperating in development, has failed to produce planned results due to the weak institutional capacity of recipients and health systems overall, as well as little synergy and coordination between international partners. Increased financial resources have allowed the rapid expansion of prevention and care services for the three diseases. Spectacular results have been achieved against malaria in Eastern African countries, but little progress has been made in the collective effort to slow down the spread of HIV/AIDS. In preparation for the upcoming Replenishment Conference of the Global Fund and prior to any further decisions to expand the use of innovative financing instruments for development, the author of this article calls the attention of policy-makers to the need to ensure the development of accompanying strategies to increase the effectiveness and impact of these instruments at country level.L’évaluation à cinq ans du Fonds mondial de lutte contre le VIH/SIDA, la tuberculose et le paludisme (GFTAM a été men

  13. A Review of Expertise and Judgment Processes for Risk Estimation

    Energy Technology Data Exchange (ETDEWEB)

    R. L. Boring

    2007-06-01

    A major challenge of risk and reliability analysis for human errors or hardware failures is the need to enlist expert opinion in areas for which adequate operational data are not available. Experts enlisted in this capacity provide probabilistic estimates of reliability, typically comprised of a measure of central tendency and uncertainty bounds. While formal guidelines for expert elicitation are readily available, they largely fail to provide a theoretical basis for expertise and judgment. This paper reviews expertise and judgment in the context of risk analysis; overviews judgment biases, the role of training, and multivariate judgments; and provides guidance on the appropriate use of atomistic and holistic judgment processes.

  14. Harnessing private sector expertise to improve complementary feeding within a regulatory framework: Where is the evidence?

    2017-10-01

    Global recognition that the complex and multicausal problems of malnutrition require all players to collaborate and to invest towards the same objective has led to increased private sector engagement as exemplified through the Scaling Up Nutrition Business Network and mechanisms for blended financing and matched funding, such as the Global Nutrition for Growth Compact. The careful steps made over the past 5 to 10 years have however not taken away or reduced the hesitation and scepticism of the public sector actors towards commercial or even social businesses. Evidence of impact or even a positive contribution of a private sector approach to intermediate nutrition outcomes is still lacking. This commentary aims to discuss the multiple ways in which private sector can leverage its expertise to improve nutrition in general, and complementary feeding in particular. It draws on specific lessons learned in Bangladesh, Côte d'Ivoire, India, Indonesia, and Madagascar on how private sector expertise has contributed, within the boundaries of a regulatory framework, to improve availability, accessibility, affordability, and adequate use of nutritious foods. It concludes that a solid evidence base regarding the contribution of private sector to complementary feeding is still lacking and that the development of a systematic learning agenda is essential to make progress in the area of private sector engagement in nutrition. © 2017 John Wiley & Sons Ltd.

  15. The Holistic Processing Account of Visual Expertise in Medical Image Perception: A Review.

    Science.gov (United States)

    Sheridan, Heather; Reingold, Eyal M

    2017-01-01

    In the field of medical image perception, the holistic processing perspective contends that experts can rapidly extract global information about the image, which can be used to guide their subsequent search of the image (Swensson, 1980; Nodine and Kundel, 1987; Kundel et al., 2007). In this review, we discuss the empirical evidence supporting three different predictions that can be derived from the holistic processing perspective: Expertise in medical image perception is domain-specific, experts use parafoveal and/or peripheral vision to process large regions of the image in parallel, and experts benefit from a rapid initial glimpse of an image. In addition, we discuss a pivotal recent study (Litchfield and Donovan, 2016) that seems to contradict the assumption that experts benefit from a rapid initial glimpse of the image. To reconcile this finding with the existing literature, we suggest that global processing may serve multiple functions that extend beyond the initial glimpse of the image. Finally, we discuss future research directions, and we highlight the connections between the holistic processing account and similar theoretical perspectives and findings from other domains of visual expertise.

Variante douce du tourisme, loin du tourisme de masse, le champ de l’écotourisme s’étend aux confins du tourisme de nature, du tourisme culturel et des pratiques scientifiques et sportives de plein air. Une définition de l’écotourisme peut être proposée à partir des six points suivants : 1/ nature et culture, 2/ le bien-être des sociétés hôtes, 3/ des touristes responsables, 4/ la participation des sociétés hôtes, 5/ la durabilité, 6/ l’art de la rencontre.Ecotourism provides an original conceptual framework that enables approaches to development that are better able to provide a more equitable distribution of income, as well as better organized and thought through initiatives which are more likely to promote a holistic sustainable local development.

    2017-02-11

    In this study, we explore the nexus between social networks and expertise development of Australian breast radiologists. Background literature has shown that a lack of appropriate social networks and interaction among certain professional group(s) may be an obstacle for knowledge acquisition, information flow and expertise sharing. To date there have not been any systematic studies investigating how social networks and expertise development are interconnected and whether this leads to improved performance for breast radiologists. This study explores the value of social networks in building expertise alongside with other constructs of performance for the Australian radiology workforce using semi-structured in-depth interviews with 17 breast radiologists. The findings from this study emphasise the influences of knowledge transfer and learning through social networks and interactions as well as knowledge acquisition and development through experience and feedback. The results also show that accessibility to learning resources and a variety of timely feedback on performance through the information and communication technologies (ICT) is likely to facilitate improved performance and build social support. We argue that radiologists' and, in particular, breast radiologists' work performance, needs to be explored not only through individual numerical characteristics but also by analysing the social context and peer support networks in which they operate and we identify multidisciplinary care as a core entity of social learning.

  20. Revisiting the Role of the Fusiform Face Area in Expertise.

    Bilalić, Merim

    2016-09-01

    The fusiform face area (FFA) is considered to be a highly specialized brain module because of its central importance for face perception. However, many researchers claim that the FFA is a general visual expertise module that distinguishes between individual examples within a single category. Here, I circumvent the shortcomings of some previous studies on the FFA controversy by using chess stimuli, which do not visually resemble faces, together with more sensitive methods of analysis such as multivariate pattern analysis. I also extend the previous research by presenting chess positions, complex scenes with multiple objects, and their interrelations to chess experts and novices as well as isolated chess objects. The first experiment demonstrates that chess expertise modulated the FFA activation when chess positions were presented. In contrast, single chess objects did not produce different activation patterns among experts and novices even when the multivariate pattern analysis was used. The second experiment focused on the single chess objects and featured an explicit task of identifying the chess objects but failed to demonstrate expertise effects in the FFA. The experiments provide support for the general expertise view of the FFA function but also extend the scope of our understanding about the function of the FFA. The FFA does not merely distinguish between different exemplars within the same category of stimuli. More likely, it parses complex multiobject stimuli that contain numerous functional and spatial relations.

  2. Explaining Differences in Scientific Expertise Use: The Politics of Pesticides

    2015-03-01

    Full Text Available Despite the growing importance of EU regulatory agencies in European decision-making, academic literature is missing a systematic explanation of how regulatory agencies actually contend with their core tasks of providing scientific advice to EU institutions. The article contributes to the theoretical explanation of when and under what conditions different uses of scientific expertise prevail. In particular, it focuses on theoretical explanations leading to strategic substantiating use of expertise followed by an empirical analysis of single case research. Substantiating expertise use refers to those practices in which an organisation seeks to promote and justify its predetermined preferences, which are based on certain values, political or economic interests. Empirical findings are discussed in the light of the theoretical expectations derived by streamlining and combining the main arguments of classical organisational and institutional theories and recent academic research. Process-tracing techniques are applied to investigate the process by which an EU regulation restricting the use of neonicotinoid pesticides (European Commission, 2013 was developed. The empirical analysis combines a variety of data sources including official documents, press releases, scientific outputs, and semi-structured interviews with the academic and industry experts involved in the process. The study finds that the interaction between high external pressure and high internal capacity leads to the strategic substantiating use of expertise, in which scientific evidence is used to promote the inclinations of actors upon which the agency depends most.

  6. Flight nursing expertise: towards a middle-range theory

    Science.gov (United States)

    Reimer, Andrew P.; Moore, Shirley M.

    2010-01-01

    Aim This paper presents a middle-range Theory of Flight Nursing Expertise. Background Rotary-wing (helicopter) medical transport has grown rapidly in the USA since its introduction, particularly during the past 5 years. Patients once considered too sick to transport are now being transported more frequently and over longer distances. Many limitations are imposed by the air medical transport environment and these require nurses to alter their practice. Data sources A literature search was conducted using Pubmed, Medline, CINAHL, secondary referencing and an Internet search from 1960 to 2008 for studies related to the focal concepts in flight nursing. Discussion The middle-range Theory of Flight Nursing Expertise is composed of nine concepts (experience, training, transport environment of care, psychomotor skills, flight nursing knowledge, cue recognition, pattern recognition, decision-making and action) and their relationships. Five propositions describe the relationships between those concepts and how they apply to flight nursing expertise. Implications for nursing After empirical testing, this theory may be a useful tool to assist novice flight nurses to attain the skills necessary to provide safe and competent care more efficiently, and may aid in designing curricula and programmes of research. Conclusion Research is needed to determine the usefulness of this theory in both rotary and fixed-wing medical transport settings, and to examine the similarities and differences related to expertise needed for different flight nurse team compositions. Curriculum and training innovations can result from increased understanding of the concepts and relationships proposed in this theory. PMID:20337803

  12. The expertise reversal effect: cognitive load and motivational explanations.

    Science.gov (United States)

    Rey, Günter Daniel; Buchwald, Florian

    2011-03-01

    The expertise reversal effect occurs when a learner's expertise moderates design principles such as the redundancy principle (i.e., redundant information should be excluded rather than included) derived from the cognitive load theory. Although this effect is supported by numerous experiments, indicating an overall large effect size, a variety of explanations have been proposed. The present experiment tested a cognitive load and a motivational explanation with 104 students, who reported a lack of experience in the presented instructional contents. They spent about 30 min with the instructional material to learn fundamental concepts about the gradient descent (a mathematical optimization algorithm), and with a retention and transfer test used as dependent measures. Each learner was randomly assigned to one cell of a 2 (either novices or experts introduced to through the instructional design presented previously) × 2 (either with or without additional text explaining the animations) between-subjects factorial design. The expertise reversal effect concerning the redundancy principle was replicated. Novices receiving additional text scored higher on retention and transfer than did novices without additional text, while this result was reversed for experts. Results suggest that this effect can be explained by the learner's cognitive load differences rather than overall motivation differences. Furthermore, a partial overlap was found between the motivational subdimension, "probability of success," and a cognitive load measure. On the practical side, instructional designers should consider the learner's level of expertise and their cognitive load when applying design principles. Further implications for adaptive learning environments are discussed.

    Full Text Available Le linguiste, dans sa volonté explicite de s'imposer comme sujet scientifique et de décrire objectivement la langue comme un objet qui lui est extérieur, est paradoxal, parce que, du fait même qu'il est habité de sa langue, il se trouve nécessairement dans l'impossibilité de remplir la tâche qu'il se propose. Le paradoxe du linguiste consiste donc en cela que, si on se permet de paraphraser l'observation de Labov, « les faits de la langue s'étudient selon la vision de tel ou tel linguiste individuel, alors que le linguiste n'existe que par son expérience personnelle des faits linguistiques ». Cela signifie très simplement que le linguiste, en tant que descripteur d'une langue, n'est opératif qu'à l'intérieur de son objet d'analyse. La crédibilité de l'analyste dépend entièrement de la position éthique qu'il prendra vis-à-vis de sa recherche.

    Depuis les années 1990, les conditions de travail se sont peu à peu imposées dans le débat social. Néanmoins, la situation reste critique. Les risques traditionnels n'ont pas disparu : les manutentions lourdes, l'exposition professionnelle aux cancérogènes, au bruit ou aux vibrations demeurent répandues... De plus, certaines " améliorations " n'ont fait que déplacer et dissimuler les problèmes, telle l'externalisation des risques grâce à la sous-traitance. Dans le même temps, les transformations du travail et des modalités de gestion de la main-d'œuvre ont fragilisé les collectifs et accru l'isolement des salariés, conduisant à une montée visible de la souffrance psychique. Face à ces évolutions, il est plus que jamais nécessaire que tous les acteurs concernés, en particulier les salariés eux-mêmes et leurs représentants, s'approprient les connaissances indispensables pour améliorer la protection de la santé sur les lieux du travail. Tel est le but de ce livre, qui renouvelle int�...

    Bonneuil, Christophe; Levidow, Les

    2012-02-01

    The World Trade Organization (WTO) dispute settlement procedure is a key arena for establishing global legal norms for what counts as relevant knowledge. As a high-profile case, the WTO trade dispute on GMOs mobilized scientific expertise in somewhat novel ways. Early on, the Panel put the dispute under the Sanitary and Phytosanitary (SPS) Agreement through a new legal ontology; it classified transgenes as potential pests and limited all environmental issues to the 'plant and animal health' category. The selection of scientific experts sought a multi-party consensus through a fast adversarial process, reflecting a specific legal epistemology. For the SPS framing, focusing on the defendant's regulatory procedures, the Panel staged scientific expertise in specific ways that set up how experts were questioned, the answers they would give, their specific role in the legal arena, and the way their statements would complement the Panel's findings. In these ways, the dispute settlement procedure co-produced legal and scientific expertise within the Panel's SPS framework. Moreover, the Panel operated a procedural turn in WTO jurisprudence by representing its findings as a purely legal-administrative judgement on whether the EC's regulatory procedures violated the SPS Agreement, while keeping implicit its own judgements on substantive risk issues. As this case illustrates, the WTO settlement procedure mobilizes scientific expertise for sophisticated, multiple aims: it recruits a source of credibility from the scientific arena, thus reinforcing the standard narrative of 'science-based trade discipline', while also constructing new scientific expertise for the main task--namely, challenging trade restrictions for being unduly cautious.

    A neural network approach to low-level user modeling is described, in the context of text editing tasks using the Jove editor. Knowledge of a user's expertise is extracted automatically, based on their interaction with Jove over a two week period. A MLP classifier which uses rprop learning and incorporates output data fuzzification is developed to classify users into one of five expertise levels. Classification into the correct level is achieved in around 80% of the cases, with misclassification being restricted to adjacent classes. The neurofuzzy system is seen to outperform not only the binary classifier of Beale [1989], but also production rule and inductive expert systems developed especially for comparison purposes in this study.

  13. Deliberate practice in dogs: a canine model of expertise.

    Helton, William S

    2007-04-01

    The acquisition of expertise is an area of controversy between those who lean more toward learning and those who lean more toward talent. Because the genetics and early life experiences of humans are not open to direct manipulation, human studies are of limited use in this debate. Studies using nonhumans as expert models may prove useful in resolving this dispute. For nonhumans to be considered proper models of human experts, there must be evidence supporting a shared acquisition mechanism. A candidate mechanism is deliberate practice. The author tested the deliberate practice theory of expertise acquisition on dogs competing in the sport of agility. The author examined the relationships between amounts of accumulated deliberate practice and agility performance measures. The author found there was a statistically significant relationship between the amount of deliberate practice and measured performance in agility dogs, even when controlling for sex, breed group, age, and height.

    Full Text Available Amongst the most significant questions we are confronted with today include the integration of the brain's micro-circuitry, our ability to build the complex social networks that underpin society and how our society impacts on our ecological environment.

    Amongst the most significant questions we are confronted with today include the integration of the brain's micro-circuitry, our ability to build the complex social networks that underpin society and how our society impacts on our ecological environment. In trying to unravel these issues one place to begin is at the level of the individual: to consider how we accumulate information about our environment, how this information leads to decisions and how our individual decisions in turn create our social environment. While this is an enormous task, we may already have at hand many of the tools we need. This article is intended to review some of the recent results in neuro-cognitive research and show how they can be extended to two very specific and interrelated types of expertise: perceptual expertise and social cognition. These two cognitive skills span a vast range of our genetic heritage. Perceptual expertise developed very early in our evolutionary history and is a highly developed part of all mammals' cognitive ability. On the other hand social cognition is most highly developed in humans in that we are able to maintain larger and more stable long term social connections with more behaviorally diverse individuals than any other species. To illustrate these ideas I will discuss board games as a toy model of social interactions as they include many of the relevant concepts: perceptual learning, decision-making, long term planning and understanding the mental states of other people.

Such models demonstrate how an expert's long exposure to a particular context influences the information they accumulate in order to make a decision.These processes are not confined to board games, we are all experts in our daily lives through long exposure to the many regularities of daily tasks and social

    In this position paper we propose means of measuring programming expertise on novice and expert programmers. Our approach is to measure the cognitive load of programmers while they assess Java/Python code in accordance with their experience in programming. Our hypothesis is that expert programmers...... encounter smaller pupillary dilation within programming problem solving tasks. We aim to evaluate our hypothesis using the EMIP Distributed Data Collection in order to confirm or reject our approach....

  19. Context-specific effects of musical expertise on audiovisual integration

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Ensemble musicians exchange auditory and visual signals that can facilitate interpersonal synchronisation. Musical expertise improves how precisely auditory and visual signals are perceptually integrated and increases sensitivity to asynchrony between them. Whether expertise improves sensitivity to audiovisual asynchrony in all instrumental contexts or only in those using sound-producing gestures that are within an observer's own motor repertoire is unclear. This study tested the hypothesis that musicians are more sensitive to audiovisual asynchrony in performances featuring their own instrument than in performances featuring other instruments. Short clips were extracted from audio-video recordings of clarinet, piano, and violin performances and presented to highly-skilled clarinettists, pianists, and violinists. Clips either maintained the audiovisual synchrony present in the original recording or were modified so that the video led or lagged behind the audio. Participants indicated whether the audio and video channels in each clip were synchronised. The range of asynchronies most often endorsed as synchronised was assessed as a measure of participants' sensitivities to audiovisual asynchrony. A positive relationship was observed between musical training and sensitivity, with data pooled across stimuli. While participants across expertise groups detected asynchronies most readily in piano stimuli and least readily in violin stimuli, pianists showed significantly better performance for piano stimuli than for either clarinet or violin. These findings suggest that, to an extent, the effects of expertise on audiovisual integration can be instrument-specific; however, the nature of the sound-producing gestures that are observed has a substantial effect on how readily asynchrony is detected as well.

    Full Text Available La réflexion s’appuie dans un premier temps sur une opposition entre deux attitudes de pianistes  à l’égard du travail à l’instrument : Gould, qui revendique une séparation d’avec le clavier pour ne privilégier que la lecture; Arrau, dont la technique au contraire vise à « faire corps » avec son piano. L’étude de ces deux démarches d’interprètes conduit à une conclusion croisée : l’abstraction gouldienne n’est rien d’autre qu’un déplacement du jeu vers d’autres instruments (ceux qui servent à la prise de son et au montage de ses enregistrements ; le « faire-corps » hérité de la culture pianistique romantique est plus dialectique que fusionnel, et en cela implique une capacité de mise à distance. A partir de cette double conclusion, on tâche enfin de repenser la place du jeu à l’instrument dans la mise en œuvre d’une interprétation, en interrogeant le dialogue qui s’instaure entre la partition telle qu’elle s’écrit et le geste tel qu’il se joue.Our study leans on an opposition between two pianists' attitudes about their work with the instrument. Gould claims a necessary separation from the keyboard in order to prioritize reading. Arrau, on the contrary, relies on a technique which consists in “being one” with his piano. The analysis of these two interprets’ behaviours leads to a crossed conclusion: the gouldian abstraction is nothing else than a displacement of the playing towards another kind of instruments, the ones he uses in sound recording and cut up; Arrau’s “being one” is more dialectic than at first sight, and it therefore implies a real distancing from the piano. This constatation leads to rethink the place of the piano playing in the setting of an interpretation, and to highlight the real dialogue which develops itself between the score as it has been written and the gesture as it is played.

    Background Expert knowledge may compensate for age-related declines in basic cognitive and sensory-motor abilities in some skill domains. We investigated the influence of age and aviation expertise (indexed by Federal Aviation Administration pilot ratings) on longitudinal flight simulator performance. Methods Over a 3-year period, 118 general aviation pilots aged 40 to 69 years were tested annually, in which their flight performance was scored in terms of 1) executing air-traffic controller communications; 2) traffic avoidance; 3) scanning cockpit instruments; 4) executing an approach to landing; and 5) a flight summary score. Results More expert pilots had better flight summary scores at baseline and showed less decline over time. Secondary analyses revealed that expertise effects were most evident in the accuracy of executing aviation communications, the measure on which performance declined most sharply over time. Regarding age, even though older pilots initially performed worse than younger pilots, over time older pilots showed less decline in flight summary scores than younger pilots. Secondary analyses revealed that the oldest pilots did well over time because their traffic avoidance performance improved more vs younger pilots. Conclusions These longitudinal findings support previous cross-sectional studies in aviation as well as non-aviation domains, which demonstrated the advantageous effect of prior experience and specialized expertise on older adults’ skilled cognitive performances.

    Using functional magnetic resonance imaging, we show for the first time that levels of musical expertise stepwise modulate higher order brain functioning. This suggests that degree of training intensity drives such cerebral plasticity. Participants (non-musicians, amateurs, and expert musicians) listened to a comprehensive set of specifically composed string quartets with hierarchically manipulated endings. In particular, we implemented 2 irregularities at musical closure that differed in salience but were both within the tonality of the piece (in-key). Behavioral sensitivity scores (d') of both transgressions perfectly separated participants according to their level of musical expertise. By contrasting brain responses to harmonic transgressions against regular endings, functional brain imaging data showed compelling evidence for stepwise modulation of brain responses by both violation strength and expertise level in a fronto-temporal network hosting universal functions of working memory and attention. Additional independent testing evidenced an advantage in visual working memory for the professionals, which could be predicted by musical training intensity. The here introduced findings of brain plasticity demonstrate the progressive impact of musical training on cognitive brain functions that may manifest well beyond the field of music processing.

    Most perceived parameters of sound (e.g. pitch, duration, timbre) can also be imagined in the absence of sound. These parameters are imagined more veridically by expert musicians than non-experts. Evidence for whether loudness is imagined, however, is conflicting. In music, the question of whether loudness is imagined is particularly relevant due to its role as a principal parameter of performance expression. This study addressed the hypothesis that the veridicality of imagined loudness improves with increasing musical expertise. Experts, novices and non-musicians imagined short passages of well-known classical music under two counterbalanced conditions: 1) while adjusting a slider to indicate imagined loudness of the music and 2) while tapping out the rhythm to indicate imagined timing. Subtests assessed music listening abilities and working memory span to determine whether these factors, also hypothesised to improve with increasing musical expertise, could account for imagery task performance. Similarity between each participant's imagined and listening loudness profiles and reference recording intensity profiles was assessed using time series analysis and dynamic time warping. The results suggest a widespread ability to imagine the loudness of familiar music. The veridicality of imagined loudness tended to be greatest for the expert musicians, supporting the predicted relationship between musical expertise and musical imagery ability.

    Purpose The current healthcare environment provides several challenges to the existing roles of healthcare professionals. The value of the professional expert is also under scrutiny. The purpose of this paper is to generate a construction of professional expertise amongst practitioners in the current healthcare environment. It used the speech-language therapy community in New Zealand (NZ) as an example. Design/methodology/approach Speech-language therapists currently practicing in NZ completed an online survey including qualitative and quantitative components. The range of experience and work settings of participants ( n=119) was representative of the workforce. Findings Participants clearly identified being "highly experienced" and "having in-depth knowledge" as essential elements of professional expertise. Thematic analysis generated two interconnected themes of a professional expert being a personal leader and teacher, and a highly experienced, knowledgeable and skilful practitioner. Additionally, practitioners needed to be seen to contribute to the community in order to be known as experts. Clinical practice was valued differently from research generation. Originality/value This study is novel in exploring a construction of professional expertise amongst practitioners in a current healthcare community. Within that community, experts could be viewed as highly effective practitioners that visibly contribute to the professional community. The study draws attention to the role of reputation and the impacts of being a clinical teacher or leader compared with pursuing a research role. This could be particularly relevant in the promotion of evidence-based practice.

    Full Text Available The goal of accelerating expertise can leave researchers and trainers in human factors, naturalistic decision making, sport science, and expertise studies concerned about seemingly insufficient application of expert performance theories, findings and methods for training macrocognitive aspects of human performance. Video-occlusion methods perfected by sports expertise researchers have great instructional utility, in some cases offering an effective and inexpensive alternative to high-fidelity simulation. A key problem for instructional designers seems to be that expertise research done in laboratory and field settings doesn’t get adequately translated into workplace training. Therefore, this article presents a framework for better linkage of expertise research/training across laboratory, field, and workplace settings. It also uses a case study to trace the development and implementation of a macrocognitive training program in the very challenging workplace of the baseball batters’ box. This training, which was embedded for a full season in a college baseball team, targeted the perceptual-cognitive skill of pitch recognition that allows expert batters to circumvent limitations of human reaction time in order to hit a 90 mile-per-hour slider. While baseball batting has few analogous skills outside of sports, the instructional design principles of the training program developed to improve batting have wider applicability and implications. Its core operational principle, supported by information processing models but challenged by ecological models, decouples the perception-action link for targeted part-task training of the perception component, in much the same way that motor components routinely are isolated to leverage instructional efficiencies. After targeted perceptual training, perception and action were recoupled via transfer-appropriate tasks inspired by in situ research tasks. Using NCAA published statistics as performance measures

    How do university training and subsequent practical experience affect expertise in clinical psychology? To answer this question we developed methods to assess psychological knowledge and the competence to diagnose, construct case conceptualizations, and plan psychotherapeutic treatment: a knowledge test and short case studies in a first study, and a complex, dynamically evolving case study in the second study. In our cross-sectional studies, psychology students, trainees in a certified postgraduate psychotherapist curriculum, and behavior therapists with more than 10 years of experience were tested (100 in total: 20 each of novice, intermediate, and advanced university students, postgraduate trainees, and therapists). Clinical knowledge and competence increased up to the level of trainees but unexpectedly decreased at the level of experienced therapists. We discuss the results against the background of expertise research and the training of clinical psychologists (in Germany). Important factors for the continuing professional development of psychotherapists are proposed. PMID:23543213

    Science in the Public Sphere presents a broad yet detailed picture of the history of science popularization from the Renaissance to the twenty-first century. Global in focus, it provides an original theoretical framework for analysing the political load of science as an instrument of cultural hegemony and giving a voice to expert and lay protagonists throughout history. Organised into a series of thematic chapters spanning diverse periods and places, this book covers subjects such as the representations of science in print, the media, classrooms and museums, orthodox and heterodox practices, the intersection of the history of science with the history of technology, and the ways in which public opinion and scientific expertise have influenced and shaped one another across the centuries. It concludes by introducing the "participatory turn" of the twenty-first century, a new paradigm of science popularization and a new way of understanding the construction of knowledge.

On rappelle néanmoins que la double évolution latitudinale au Crétacé et au Paléogène du Nord vers le Sud dans l'actuel hémisphère nord et du Sud vers le Nord dans l'actuel hémisphère sud rend peu crédibles les interprétations purement latitudino-climatiques de ces dépôts phosphatés.

    2012-08-01

    Full Text Available This paper examines in depth the current phenomenon of globalization and its trends; its impact, positive or negative which is the cornerstone of the current restructuring of the global economy; the nature and consequences of the globalization of trade and financial services; the operations and impact of the multinationals; and the hierarchy of countries based on their relative importance in the global economy, and its consequences. The paper then distinguishes between real and virtual globalization and its impact on economic growth; its inclusive and exclusive dynamics and their consequences for individual and corporate economic actors. The paper then addresses the information society, a phenomenon that accompanies and significantly facilitates globalization through drastic and significant improvements in communications and transport. The Internet and electronic devices used for massive surveillance, the collection of personal information, and the systematic erosion of privacy - the Internet as Panopticon – are also examined.Finally, the paper analyzes the vulnerability of the global information society to crime, especially economic and identity theft crimes, ironically facilitated especially by its global and inter-connected nature. Even the global improvement in the financial conditions of most people worldwide, creating more wealth and economic well being, has negative, and at times criminal, repercussions, impacting especially indigenous or vulnerable populations, fauna and flora. Most illustrative examples of these criminal trends are trafficking in people, endangered species, animal organs and products, antiquities, art and various types of counterfeiting. In conclusion there is a clear and close connection between globalization, the information society, criminal behavior and a society’s ability to effectively protect itself from piracy and the violations of a country’s laws and treaties.Ce document examine en profondeur le ph

  10. Analytical determination of 3-D global modes in Rayleigh-Benard-Poiseuille-type mixed convection flow; Determination analytique des modes globaux tridimensionnels en ecoulement de convection mixte du type Rayleigh-Benard-Poiseuille

    This analytical study deals with the spatio-temporal evolution of linear thermo-convective instabilities in a horizontal fluid layer heated from below (the Rayleigh--Benard system) and subject to a horizontal pressure gradient (Poiseuille flow). The novelty consists of a spatially inhomogeneous temperature, in the form of a two-dimensional bump imposed on the lower plate, while the upper plate is kept at a constant temperature. The inhomogeneous boundary temperature and the mean flow of the Rayleigh--Benard--Poiseuille system break the symmetries of the classical Rayleigh--Benard system. The instabilities of interest are therefore spatially localised packets of convection rolls. If a mode of this type is synchronized, it is called a global mode. Assuming that the characteristic scale of the spatial variation of the lower plate temperature is large compared to the wavelength of the rolls, global modes are sought in the form of Eigenmodes in the confined vertical direction, modulated by a two-dimensional WKBJ expansion in the slowly-varying horizontal directions. Such an expansion breaks down at points where the group velocity of the instability vanishes, i.e. at WKBJ turning points. In the neighbourhood of one such point, located at the top of the temperature bump, the boundedness of the solution imposes a selection criterion for the global modes which provides the growth rate (or equivalently the critical threshold), the frequency and the wave vector of the most amplified global mode. This study thus generalizes to two-dimensional cases the methods used and the results obtained for one-dimensional inhomogeneities. The analysis is first applied to a simplified governing equation obtained by an envelope formalism and the analytical results are compared with numerical solutions of the amplitude equation. The formalism is finally applied to the Rayleigh--Benard--Poiseuille system described by the Navier--Stokes equations with the Boussinesq approximation. (author)

  16. Music Reading Expertise Selectively Improves Categorical Judgment with Musical Notation

    Directory of Open Access Journals (Sweden)

    Yetta Kwailing Wong

    2011-05-01

    Full Text Available Different domains of perceptual expertise often lead to different hemispheric engagement (e.g. Kanwisher et al., 1997. Recent work suggests that the neural substrates engaged in musical reading are shifted from left hemisphere novice processing to bilateral processing in experts (Wong & Gauthier, 2010. To relate this shift to behavior, we tested whether music-reading training improves categorical and coordinate perceptual judgments, which are argued to rely on the left and right hemisphere respectively (Kosslyn et al., 1989. Music-reading experts and novices judged whether two sequentially presented music sequences were identical. The notes were either on a staff (categorical or without a staff (coordinate in either trained or untrained (90° rotated orientations. Experts performed better than novices for categorical judgments, and the advantage was larger for the trained than untrained orientation. The two groups performed similarly for coordinate judgments. Music-reading fluency predicted performance in categorical judgments in the trained orientation in experts, while it predicted performance in all conditions in novices. This suggests that music-reading training selectively improves categorical judgments in the trained orientation, while music-reading ability in novices reflects general perceptual ability with notes. Future studies will clarify how these findings are related to the hemispheric shift in music-reading expertise.

    Motor resonance processes that occur when observing an individual perform an action may be modulated by acquired visuomotor expertise. We used the event-related potential (EEG/ERP) technique to investigate the ability to automatically recognize a subtle difference between very similar novel contemporary dance movements. Twelve professional dancers and twelve non-dancers were shown 212 pairs of videos of complex whole-body movements that lasted 3s. The second of each pair was the repetition of the previous movement or a slight variation of it (deviance). The participants were engaged in a secondary attentional task. Modulation of a larger centro-parietal N400 effect and a reduction of the Late Positivity amplitude (repetition suppression effect) were identified in response to deviant stimuli only in the dancers. Source reconstruction (swLORETA) showed activations in biological motion, body and face processing related areas, and fronto-parietal and limbic systems. The current findings provide evidence that acquired dance expertise modifies the ability to visually code whole-body complex movements. Copyright © 2017 Elsevier Ltd. All rights reserved.

  18. Forensic entomology: implementing quality assurance for expertise work.

    Science.gov (United States)

    Gaudry, Emmanuel; Dourel, Laurent

    2013-09-01

    The Department of Forensic Entomology (Institut de Recherche Criminelle de la Gendarmerie Nationale, France) was accredited by the French Committee of Accreditation (Cofrac's Healthcare section) in October 2007 on the basis of NF EN ISO/CEI 17025 standard. It was the first accreditation in this specific field of forensic sciences in France and in Europe. The present paper introduces the accreditation process in forensic entomology (FE) through the experience of the Department of Forensic Entomology. Based upon the identification of necrophagous insects and the study of their biology, FE must, as any other expertise work in forensic sciences, demonstrate integrity and good working practice to satisfy both the courts and the scientific community. FE does not, strictly speaking, follow an analytical method. This could explain why, to make up for a lack of appropriate quality reference, a specific documentation was drafted and written by the staff of the Department of Forensic Entomology in order to define working methods complying with quality standards (testing methods). A quality assurance system is laborious to set up and maintain and can be perceived as complex, time-consuming and never-ending. However, a survey performed in 2011 revealed that the accreditation process in the frame of expertise work has led to new well-defined working habits, based on an effort at transparency. It also requires constant questioning and a proactive approach, both profitable for customers (magistrates, investigators) and analysts (forensic entomologists).

  19. Expertise facilitates the transfer of anticipation skill across domains.

    Rosalie, Simon M; Müller, Sean

    2014-02-01

    It is unclear whether perceptual-motor skill transfer is based upon similarity between the learning and transfer domains per identical elements theory, or facilitated by an understanding of underlying principles in accordance with general principle theory. Here, the predictions of identical elements theory, general principle theory, and aspects of a recently proposed model for the transfer of perceptual-motor skill with respect to expertise in the learning and transfer domains are examined. The capabilities of expert karate athletes, near-expert karate athletes, and novices to anticipate and respond to stimulus skills derived from taekwondo and Australian football were investigated in ecologically valid contexts using an in situ temporal occlusion paradigm and complex whole-body perceptual-motor skills. Results indicated that the karate experts and near-experts are as capable of using visual information to anticipate and guide motor skill responses as domain experts and near-experts in the taekwondo transfer domain, but only karate experts could perform like domain experts in the Australian football transfer domain. Findings suggest that transfer of anticipation skill is based upon expertise and an understanding of principles but may be supplemented by similarities that exist between the stimulus and response elements of the learning and transfer domains.

    We examined the influence of age and expertise on pilot decision making. Older and younger expert and novice pilots read at their own pace scenarios describing simpler or more complex flight situations. Then in a standard interview they discussed the scenario problem and how they would respond. Protocols were coded for identification of problem and solutions to this problem, and frequency of elaborations on problem and solution. Scenario comprehension was measured as differential reading time allocation to problem-critical information and scenario memory by the accuracy of answering questions about the scenarios after the interview. All groups accurately identified the problems, but experts elaborated problem descriptions more than novices did. Experts also spent more time reading critical information in the complex scenarios, which may reflect time needed to develop elaborate situation models of the problems. Expertise comprehension benefits were similar for older and younger pilots. Older experts were especially likely to elaborate the problem compared to younger experts, while older novices were less likely to elaborate the problem and to identify appropriate solutions compared to their younger counterparts. The findings suggest age invariance in knowledge-based comprehension relevant to pilot decision making.

  1. Qualitative Understanding of Magnetism at Three Levels of Expertise

    2010-03-01

    This work set out to investigate the state of qualitative understanding of magnetism at various stages of expertise, and what approaches to problem-solving are used across the spectrum of expertise. We studied three groups: 10 novices, 10 experts-in-training, and 11 experts. Data collection involved structured interviews during which participants solved a series of non-standard problems designed to test for conceptual understanding of magnetism. The interviews were analyzed using a grounded theory approach. None of the novices and only a few of the experts in training showed a strong understanding of inductance, magnetic energy, and magnetic pressure; and for the most part they tended not to approach problems visually. Novices frequently described gist memories of demonstrations, text book problems, and rules (heuristics). However, these fragmentary mental models were not complete enough to allow them to reason productively. Experts-in-training were able to solve problems that the novices were not able to solve, many times simply because they had greater recall of the material, and therefore more confidence in their facts. Much of their thinking was concrete, based on mentally manipulating objects. The experts solved most of the problems in ways that were both effective and efficient. Part of the efficiency derived from their ability to visualize and thus reason in terms of field lines.

  2. Social and psychological risks expertise in crisis communities

    Emerging and development of crises in the communities leads to considerable increase of individual's risks' quality and quantity. Irrespectively of risk scale - partial or total influence on a community - a number of tendencies of risks increase could be identified. On social level risks result from the tendency of social protection decrease and restriction in free choice of activities' forms and kinds. On group level confrontation and clashes emerge, increase intolerance and decrease tolerance are identified. On interpersonal (micro group) level aggression and abuse intensify. On individual level a complex of negative psychological statuses develops, which is diverse both as for its content and forms. Reasons of crisis development and its dynamics determine the content and concrete forms of risks on all levels. Systematic description of risks and development of psychological support programmes for population in risk presupposes organization and delivering of comprehensive social and psychological expertise of situation. Such an expertise makes it possible to unite in a comprehensive model of the multi-professional descriptions of crisis situations on the above mentioned levels, the subjective concepts of the population (or its separate groups) together with evaluation of various projects and programmes on crisis coping and risks decrease options.

  3. Teacher knowledge, instructional expertise, and the development of reading proficiency.

    2009-01-01

    Teacher knowledge and instructional expertise have been found in correlational and pre- and posttest studies to be related to student reading achievement. This article summarizes data presented in this special issue and additional research to address four questions: (a) What do expert reading teachers know? (b) Why do teachers need to acquire this knowledge? (c) Do teachers believe they have this knowledge? and (d) Are teachers being adequately prepared to teach reading? Well-designed studies relevant to this topic have been sparse with a noticeable lack of attention given to identifying specific causal links between teacher knowledge, teaching expertise, and student reading achievement. Until the appropriate research designs and methodologies are applied to address the question of causal effects, conclusions about the specific content that teachers must know and the instructional practices that are most beneficial in presenting this content are preliminary at best. Future studies of the effect of essential reading content knowledge must be extended beyond word-level skills to vocabulary, reading comprehension, and writing.

    Animal life can be perceived as the selective use of information for maximizing survival and reproduction. All organisms including bacteria and protists rely on genetic networks to build and modulate sophisticated structures and biochemical mechanisms for perceiving information and responding to environmental changes. Animals, however, have gone through a series of innovations that dramatically increased their capacity to acquire, retain and act upon information. Multicellularity was associated with the evolution of the nervous system, which took over many tasks of internal communication and coordination. This paved the way for the evolution of learning, initially based on individual experience and later also via social interactions. The increased importance of social learning also led to the evolution of language in a single lineage. Individuals' ability to dramatically increase performance via learning may have led to an evolutionary cycle of increased lifespan and greater investment in cognitive abilities, as well as in the time necessary for the development and refinement of expertise. We still know little, however, about the evolutionary biology, genetics and neurobiological mechanisms that underlie such expertise and its development.This article is part of the themed issue 'Process and pattern in innovations from cells to societies'. © 2017 The Author(s).

    2015-08-01

    We examined the effects of framing and order of presentation on professional philosophers' judgments about a moral puzzle case (the "trolley problem") and a version of the Tversky & Kahneman "Asian disease" scenario. Professional philosophers exhibited substantial framing effects and order effects, and were no less subject to such effects than was a comparison group of non-philosopher academic participants. Framing and order effects were not reduced by a forced delay during which participants were encouraged to consider "different variants of the scenario or different ways of describing the case". Nor were framing and order effects lower among participants reporting familiarity with the trolley problem or with loss-aversion framing effects, nor among those reporting having had a stable opinion on the issues before participating the experiment, nor among those reporting expertise on the very issues in question. Thus, for these scenario types, neither framing effects nor order effects appear to be reduced even by high levels of academic expertise. Copyright © 2015 Elsevier B.V. All rights reserved.

    How does expertise influence the perception of representational and abstract paintings? We asked 20 experts on art history and 20 laypersons to explore and evaluate a series of paintings ranging in style from representational to abstract in five categories. We compared subjective esthetic judgments and emotional evaluations, gaze patterns, and electrodermal reactivity between the two groups of participants. The level of abstraction affected esthetic judgments and emotional valence ratings of the laypersons but had no effect on the opinions of the experts: the laypersons’ esthetic and emotional ratings were highest for representational paintings and lowest for abstract paintings, whereas the opinions of the experts were independent of the abstraction level. The gaze patterns of both groups changed as the level of abstraction increased: the number of fixations and the length of the scanpaths increased while the duration of the fixations decreased. The viewing strategies – reflected in the target, location, and path of the fixations – however indicated that experts and laypersons paid attention to different aspects of the paintings. The electrodermal reactivity did not vary according to the level of abstraction in either group but expertise was reflected in weaker responses, compared with laypersons, to information received about the paintings.

    The whole of the experimental methods described (animal preparation, achievement of a precise physiological technique, dosimetry, biological information processing) allowed us to follow the changes for 15 days in the spontaneous and evoked electroencephalogram activities of rabbits submitted to a non-lethal 400 rads whole-body gamma-irradiation. Behavioural troubles, changes in the arousal state and the spontaneous electrical activity of the neo-cortex and hippocampus were noticed constantly together with an enhanced cortical excitability, and the appearance of elements of the paroxystic series sometimes in contrast with a general decrease in amplitude. After a visual stimulus the general morphology of evoked activities at the level of the primary visual areas and hippocampus was unchanged, but enhanced latencies and delays, less systematic modifications in amplitudes seemed to show out a direct effect of radiations on the nervous system and sensorial activities; these troubles seemed to occur independently from the basic electrical activity. As a whole, the changes observed were usually transitory and varied with each individual. Finally an assumption is made to explain the mechanism of arousal troubles and the general evolution of spontaneous electrical activity in the brain.

    2006-09-01

    Full Text Available Abstract The Cri du Chat syndrome (CdCS is a genetic disease resulting from a deletion of variable size occurring on the short arm of chromosome 5 (5p-. The incidence ranges from 1:15,000 to 1:50,000 live-born infants. The main clinical features are a high-pitched monochromatic cry, microcephaly, broad nasal bridge, epicanthal folds, micrognathia, abnormal dermatoglyphics, and severe psychomotor and mental retardation. Malformations, although not very frequent, may be present: cardiac, neurological and renal abnormalities, preauricular tags, syndactyly, hypospadias, and cryptorchidism. Molecular cytogenetic analysis has allowed a cytogenetic and phenotypic map of 5p to be defined, even if results from the studies reported up to now are not completely in agreement. Genotype-phenotype correlation studies showed a clinical and cytogenetic variability. The identification of phenotypic subsets associated with a specific size and type of deletion is of diagnostic and prognostic relevance. Specific growth and psychomotor development charts have been established. Two genes, Semaphorin F (SEMAF and δ-catenin (CTNND2, which have been mapped to the "critical regions", are potentially involved in cerebral development and their deletion may be associated with mental retardation in CdCS patients. Deletion of the telomerase reverse transcriptase (hTERT gene, localised to 5p15.33, could contribute to the phenotypic changes in CdCS. The critical regions were recently refined by using array comparative genomic hybridisation. The cat-like cry critical region was further narrowed using quantitative polymerase chain reaction (PCR and three candidate genes were characterised in this region. The diagnosis is based on typical clinical manifestations. Karyotype analysis and, in doubtful cases, FISH analysis will confirm the diagnosis. There is no specific therapy for CdCS but early rehabilitative and educational interventions improve the prognosis and considerable

    Full Text Available Le paysage est de plus en plus perçu comme une ressource. À ce titre, il est nécessaire de trouver des instruments juridiques, politiques ou économiques susceptibles de gérer cette « ressource-paysage » sur le long terme. Le gouvernement suisse a introduit récemment l’instrument des parcs naturels régionaux, organisés selon le modèle français, dans sa législation de protection de la nature et du paysage. Une mise en regard des nouveaux parcs avec des structures de gestion beaucoup plus anciennes, les bourgeoisies et les corporations, permet de mettre en évidence les forces et les faiblesses de chacun de ces instruments dans leur contribution à résoudre les rivalités d’usage entre acteurs utilisant ou influençant la ressource paysage. Cette comparaison permet de formuler des recommandations pratiques concernant la gestion de cette ressource.The landscape is increasingly perceived as a resource. For this reason, it is necessary to find legal, political and economic instruments that will succeed in managing this “resource landscape” in the long term. The Swiss government recently introduced the instrument of regional nature parks into the legislation governing nature and landscape preservation; the proposed parks are organized on the basis of the French model. The examination of the new parks from the perspective of much older management structures, i.e. the civic municipalities (bourgeoisies and corporations, makes it possible to demonstrate the strengths and weaknesses of each of these instruments in their contribution to the resolution of use rivalries between actors who use or influence the resource landscape. This comparison also enables the formulation of practical recommendations regarding the management of this resource.

    Jacqueline Best argues that the changes in International Monetary Fund, World Bank and donor policies in the 1990s, towards what some have called the 'Post-Washington Consensus,' were driven by an erosion of expert authority and an increasing preoccupation with policy failure. Failures such as the Asian financial crisis and the decades of despair in sub-Saharan Africa led these institutions to develop governance strategies designed to avoid failure: fostering country ownership, developing glo...

    Full Text Available L’histoire de l’écologie politique, telle qu’elle s’est déroulée en France au cours des deux dernières décennies, peut être interprétée comme étant orientée par une contestation progressive du rôle de l’expertise scientifique dans la détermination exclusive des actions qu’il convient d’entreprendre pour faire face à la crise environnementale. Un telle évolution est salutaire en ce qu’elle a libéré un espace de réflexion et d’action politique. Or la configuration actuelle du problème du réchauffement climatique est telle qu’elle menace de faire perdre cet avantage. Aussi convient-il de travailler à reconfigurer la crise écologique pensée sous les espèces du réchauffement climatique afin de pouvoir donner un sens à ce qu nous arrive et ainsi donner consistance au présent de l’action et de l’initiative.

  6. Expertise of using striking techniques for power stroke in badminton.

    Zhu, Qin

    2013-10-01

    Two striking techniques (fast swing and angled striking) were examined to see if they allowed effective use of string tension for the power stroke in badminton. 12 participants (4 novices, 4 recreational, and 4 expert badminton players) were recorded by a fast-speed camera while striking a shuttlecock with racquets of 8 different string tensions. The peak speed of the shuttlecock, the racquet angle and the shuttlecock angle were analyzed. The results showed that expert players succeeded in using both striking techniques to overcome the constraint of string tension and produce a consistently superior stroke. Failure to use either striking technique resulted in inferior performance that was constrained by string tension. Expertise in badminton allows the necessary motor adjustments based on the affordance perception of the string tension.

    Understanding clinical reasoning is essential for patient care and medical education. Dual-processing theory suggests that nonanalytic reasoning is an essential aspect of expertise; however, assessing nonanalytic reasoning is challenging because it is believed to occur on the subconscious level. This assumption makes concurrent verbal protocols less reliable assessment tools. Functional magnetic resonance imaging was used to explore the neural basis of nonanalytic reasoning in internal medicine interns (novices) and board-certified staff internists (experts) while completing United States Medical Licensing Examination and American Board of Internal Medicine multiple-choice questions. The results demonstrated that novices and experts share a common neural network in addition to nonoverlapping neural resources. However, experts manifested greater neural processing efficiency in regions such as the prefrontal cortex during nonanalytical reasoning. These findings reveal a multinetwork system that supports the dual-process mode of expert clinical reasoning during medical evaluation.

    Full Text Available Adults and infants can use the statistical properties of syllable sequences to extract words from continuous speech. Here we present a review of a series of electrophysiological studies investigating 1 Speech segmentation resulting from exposure to spoken and sung sequences 2 The extraction of linguistic versus musical information from a sung sequence3 Differences between musicians and nonmusicians in both linguistic and musical dimensions. The results show that segmentation is better after exposure to sung compared to spoken material and moreover, that linguistic structure is better learned than the musical structure when using sung material. In addition, musical expertise facilitates the learning of both linguistic and musical structures. Finally, an electrophysiological approach, which directly measures brain activity, appears to be more sensitive than a behavioral one.

    A major question in the domain of face perception is whether faces comprise a distinct visual category that is processed by specialized mechanisms, or whether face processing merely represents an extreme case of visual expertise. Here, we examined O.H, a 22 years old woman with congenital prosopagnosia (CP), who despite her severe deficits in face processing, acquired superior recognition skills for horses. To compare the nature of face and horse processing, we utilised the inversion manipulation, known to disproportionally affect faces compared to other objects, with both faces and horses. O.H's performance was compared to data obtained from two control groups that were either horse experts, or non-experts. As expected, both control groups exhibited the face inversion effect, while O.H did not show the effect, but importantly, none of the participants showed an inversion effect for horses. Finally, gaze behaviour toward upright and inverted faces and horses was indicative of visual skill but in a distinct fashion for each category. Particularly, both control groups showed different gaze patterns for upright compared to inverted faces, while O.H presented a similar gaze pattern for the two orientations that differed from that of the two control groups. In contrast, O.H and the horse experts exhibited a similar gaze pattern for upright and inverted horses, while non-experts showed different gaze patterns for different orientations. Taken together, these results suggest that visual expertise can be acquired independently from the mechanisms mediating face recognition. Copyright © 2015 Elsevier Ltd. All rights reserved.

Il est au contact de divers minerais, particulièrement la silice, particule qui présente un risque certain de développement des maladies pulmonaires connues sous le nom de silicose. Le but de notre travail est de préciser le profil épidémiologique, clinique, radiologique et évolutif des patients puisatiers silicotiques. C'est une étude rétrospective concernant 54 cas de puisatiers ayant une silicose, colligés au service des maladies respiratoires du CHU Ibn Rochd de Casablanca, de Mars 1997 à Janvier 2016. Tous les malades étaient des puisatiers, de sexe masculin, avec une moyenne d'âge de 50 ans. Le tabagisme était retrouvé dans 36 cas et un antécédent de tuberculose était noté dans huit cas. La radiographie thoracique retrouvait des grandes opacités dans 39 cas, des petites opacités dans 15 cas, et un épaississement des septats dans 11 cas. Ce tableau de silicose s'était compliqué d'une surinfection bactérienne dans 37% des cas, d' un pneumothorax dans 4% des cas et d'une tuberculose dans 20% des cas. La prise en charge thérapeutique était celle des complications. La déclaration de la maladie professionnelle et de l'indemnisation était faite. L'évolution était bonne dans 12 cas, stationnaire dans 17 cas et mauvaise dans 16 cas. La silicose est une pneumoconiose fréquente chez les puisatiers. Elle retentit sur la fonction respiratoire. Nous soulignons l'association fréquente de tuberculose et nous insistons sur la prévention qui reste le meilleur traitement. PMID:28292119

    Many scientists agree that expertise requires both innate talent and proper training. Nevertheless, the highly influential deliberate practice model (DPM) of expertise holds that talent does not exist or makes a negligible contribution to performance. It predicts that initial performance will be unrelated to achieving expertise and that 10 years of deliberate practice is necessary. We tested these predictions in the domain of sprinting. In Studies 1 and 2 we reviewed biographies of 15 Olympic...

  17. The transformation of (bio)ethics expertise in a world of ethical pluralism.

    Science.gov (United States)

    Kovács, József

    2010-12-01

    Today, bioethics experts have an increasing role in public life. However, the question arises: what does bioethics expertise really mean? Can there be such a thing in our globalised world characterised by ethical pluralism? I will argue that bioethics as a discipline represents the transformation of ethics expertise from a hard to a soft form of it. Bioethics was born as a reaction to the growing awareness of ethical pluralism, and it denied the hard form of normative-prescriptive ethics expertise (the ability to determine what is the right course of action for others), particularly in its medical ethics form. In contrast, the traditional medical ethics model, and pre-modern societies in general, believed in hard normative ethics expertise. From this followed the characteristic paternalism of traditional medical practice: if physicians were experts in moral matters as well, if they knew what the right course of action to choose was, then they had a right to benevolently force this course of action on their patients. The remnants of this doctrine, although rarely stated explicitly, still can often be seen in clinical practice. The whole bioethics movement can be seen as a radical denial of the doctrine of physician's hard expertise in moral matters. Bioethics, however, represents a type of soft ethics expertise (mainly value sensitivity). Hence follows the seeming paradox of bioethics expertise: bioethics is both a denial of ethics expertise (in its hard form) as well as a type of (soft) ethics expertise.

    Le rechauffement climatique predit pour les prochaines decennies, aura des impacts majeurs sur le pergelisol qui sont tres peu documentes pour l'instant. La presente etude a pour but d'evaluer ces impacts sur les proprietes mecaniques du pergelisol et sa stabilite a long terme. Une nouvelle technique d'essai de penetration au cone a taux de deformation controle, a ete developpee pour caracteriser en place le pergelisol. Ces essais geotechniques et la mesure de differentes proprietes physiques ont ete effectues sur une butte de pergelisol au cours du printemps 2000. Le developpement et l'utilisation d'un modele geothermique 1D tenant compte de la thermodependance du comportement mecanique ont permis d'evaluer que les etendues de pergelisol chaud deviendraient instables a la suite d'un rechauffement de l'ordre de 5°C sur cent ans. En effet, la resistance mecanique du pergelisol diminuera alors rapidement jusqu'a 11,6 MPa, ce qui correspond a une perte relative de 98% de la resistance par rapport a un scenario sans rechauffement.

  1. The effects of alphabet and expertise on letter perception.

    Science.gov (United States)

    Wiley, Robert W; Wilson, Colin; Rapp, Brenda

    2016-08-01

    Long-standing questions in human perception concern the nature of the visual features that underlie letter recognition and the extent to which the visual processing of letters is affected by differences in alphabets and levels of viewer expertise. We examined these issues in a novel approach using a same-different judgment task on pairs of letters from the Arabic alphabet with 2 participant groups: 1 with no prior exposure to Arabic and 1 with reading proficiency. Hierarchical clustering and linear mixed-effects modeling of reaction times and accuracy provide evidence that both the specific characteristics of the alphabet and observers' previous experience with it affect how letters are perceived and visually processed. The findings of this research further our understanding of the multiple factors that affect letter perception and support the view of a visual system that dynamically adjusts its weighting of visual features as expert readers come to more efficiently and effectively discriminate the letters of the specific alphabet they are viewing.

  2. Critical Pedagogy as Collective Social Expertise in Higher Education

    Directory of Open Access Journals (Sweden)

    Juha Suoranta

    2006-10-01

    Full Text Available In this article, dedicated to the revolutionary educational work of Peter McLaren, we will deal with the question of practical teaching methods in higher education from the point of view of critical pedagogy. We argue that nowadays teaching and learning in educational and social sciences are too often meaningless from the point of view of critical collective learning. Thus the central task in critical pedagogy, and in reform of higher education, is to understand the oppressive aspects of present college life and overall society in order to generate pedagogical, individual and societal transformation while developing pedagogical strategies and study methods that work toward the elimination of various forms of subordination based on class, gender, race and sexual orientation, and strengthen students’ possibilities for genuine collective learning while empowering them to fight against inequalities in the world. Our reflections stem from our academic life and teaching experiences both in Finland and the U.S. We suggest that in order to teach critically, educators need to use more collaborative and collective teaching and learning methods. Thus the idea of collective social expertise becomes a core aim of teaching in the context of critical pedagogy.

    2006-12-22

    Ultrasonic modeling and simulation are more and more widely used by the different actors of industrial NDT. The applications are numerous and show a great variety: help for diagnosis, data reconstruction, performance demonstration, probe design and inspection parameters settling, virtual testing etc. The CEA (the French Atomic Energy Commission) is strongly involved in this evolution with the development of the CIVA expertise platform which gathers in the same software advanced processing and modeling tools. In the aim of fulfilling requirements of an intensive use the choice has been made to mainly adopt semi-analytical approximated methods. The wave propagation modeling is based on an integral formulation of the radiated field and applies the so-called pencil method. The modeling of beam-defect interaction and echoes formation mechanisms apply approximated theories such as Kirchhoff approximation or GTD. Over the years and with successive versions of the software, this approach is enriched by adaptations and improvements of the existing models or by new models, in order to extend the field of applicability of the simulation.

    The purpose of this study was to examine the effect of intensive practice in table tennis on perceptual, decision-making and motor-systems. Groups of elite (HL, N.=11), intermediate (LL, N.=6) and control players (CC, N.=11) performed tasks of different levels. All subjects underwent to reaction time test and response time test consisting of a pointing task to targets placed at distinct distances (15 and 25 cm away) on the right and left sides. Only the HL and LL groups were requested to perform the ball speed test in forehand and backhand condition. In the CC group reaction time was higher compared to the HL (P<0.05) group. In the response time test, there was a significant main effect of distance (P<0.0001) and the tennis table expertise (P=0.011). In the ball speed test HL players were consistently faster compared to LL players in both forehand stroke (P<0.0001) and backhand stroke (P<0.0001). Overall, the forehand stroke was significantly faster than the backhand stroke. We can conclude that table tennis players have shorter response times than non-athletes and the tasks of reaction time and response time are incapable to distinguish between the performance of well-trained table tennis players and that of intermediate players, but the ball speed test seems to be able to do it.

  5. Moody experts --- How mood and expertise influence judgmental anchoring

    Directory of Open Access Journals (Sweden)

    Birte Englich

    2009-02-01

    Full Text Available Anchoring effects, the assimilation of numerical estimates to previously considered standards, are highly robust. Two studies examined whether mood and expertise jointly moderate the magnitude of anchoring. Previous research has demonstrated that happy mood induces judges to process information in a less thorough manner than sad mood, which means that happy judges tend to be more susceptible to unwanted influences. However, this may not be true for anchoring effects. Because anchoring results from an elaborate process of selective knowledge activation, more thorough processing should lead to more anchoring; as a result, sad judges should show stronger anchoring effects than happy judges and happy judges may even remain uninfluenced by the given anchors. Because information processing of experts may be relatively independent of their mood, however, mood may influence anchoring only in non-experts. Results of two studies on legal decision-making (Study 1 and numeric estimates (Study 2 are consistent with these expectations. These findings suggest that, at least for non-experts, positive mood may eliminate the otherwise robust anchoring effect.

  6. Stock investment funds in Brazil: performance and management expertise

    2012-01-01

    Full Text Available This article analyzes the stock investment fund market in Brazil and proposes dynamic rankings constructed from different risk-return metrics, during the period from 1998 to 2009. We find an uncommon level of persistence, mainly among the best performing funds, due to the expertise of the managers. The quadrimestral rebalancing of the portfolios based on these rankings permits inferring that in scenarios characterized as economic booms or recovery of financial markets, the strategies with equal participation in winner funds provides significantly higher average monthly gains, reduction of risk associated with diversification and consequently enhanced performance in relation to market or sector benchmarks. This evidence is robust to the use of different performance metrics for fund selection, indicating that active investors in winning funds demand good performance not only in terms of the Sharpe ratio, but also with respect to other metrics, such as the Treynor, Calmar and Sortino ratios. In these optimistic scenarios, only the industrial sector index (INDX provided returns compatible with those of these fund’s portfolios. However, during periods of crisis, no strategy involving the funds managed to provide hedge levels characteristic of the electric energy sector index (IEE, so it can be said that the majority of investing strategies are dominated in gain-risk criteria by sector or market indexes, with the exception of value-weighted portfolios composed of losing funds, a signal that the usual passive investors in large funds indexed to the Ibovespa can be presenting a greater level of inertia.

  7. [Politics: which contribution can ethical expertise give biopolitical decisions?].

    Weber-Hassemer, Kristiane

    2008-08-01

    Research in the life sciences is developing at a rapid pace, has profound implications in terms of its effects on human nature and touches upon the self-conceptions of both the individual and society. In order to determine how this research and its application in all phases of human life should be assessed on the moral level, and whether it should be subject to regulation, the involvement of all disciplines--in the natural sciences, medicine, philosophy, law and the social sciences--that can contribute knowledge for the purpose of guidance is indispensable. Political decisions should be preceded by a wide-ranging debate within society encompassing all relevant groups and the media. Alongside discourse confined to specialists and their forums, a particular part can be played by the institution of ethics committees with an interdisciplinary, pluralistic membership. Their work can contribute to the stimulation of social debate and to ensuring that it is conducted on a suitably high level. In our knowledge society, Government and Parliament lack the information necessary to guide their decisions, and therefore require external expertise to provide a solid foundation for them. In the field of bioethics, however, the relationship between advisory activity and parliamentary decision-making proves is not without problems, because, in addition to rational criteria and party-political considerations, personal moral judgements are not only unavoidable but also legitimate, though they are not always made transparent.

    2017-04-01

    Episodes of dialytic Acute Kidney Injury (AKI stage III KDIGO) can lead to chronic kidney disease (CKD), even after a long time. Prelimary data indicate that the relationship between AKI and CKD is affected by dialysis technical modalities and factors in part modifiable, such as an early dialysis timing, dose adeguacy, continuous treatment, use of biocompatible membranes and regional citrate anticoagulation. However, in most ICUs involvement of nephrologist consultant is marginal. Of more, nephrological follow-up after discharge, which allows to slow down the progression rate of CKD even just by a correct pharmacological and dietetic approach (sartans, ACEis), is an uncommon practice. Indeed, a better organ survival could lead to a delay of the dialytic treatment, reducing the costs sustained by the National Health Service. To face such challenges locally, in Piedmont and Aosta Valley the Dialysis Units were required to put themselves at disposal for ICU needs both in terms of dedicated staff and resources. Additionally, since many years consultant nephrologists have established the "Acuti" work-group, which has been able to provide an high level of professional expertise, while incentivizing innovation and training in ICU environment. In order to cope with these new requirements a redefinition of the nephrologist's role in ICU through a constant exchange with the intensive care background is needed.

  9. Measurements of the Russian identity: Sociological assessments and humanitarian expertise

    2016-12-01

    Full Text Available Within the framework of the existing scientific approaches, the authors consider the process of ethnization of the Russians’ mass consciousness under the expanding internal and external labor migration in Russia. The article presents the results of the situational analysis and humanitarian expertise of the set of key challenges determined by the migration. Based on the statistics, opinion polls data and expert assessments the article describes the empirical model of the identity of ethnic Russian population of Moscow and the Moscow region as the major centers of attraction for international migrants. The comprehensive analysis of the issues and controversies of the labor migration in the region and relationships of ethnic groups living in the region is preceded by the description of the identity of native inhabitants of the region as perceived by the ethnic Russian population. To measure the identity for the axiological ranking the authors use a number of relatively independent variables besides ethnic (national identity: religious involvement, civilizational orientation, cultural, professional, territorial and other important features. Thus, the authors present a multi-dimensional space of identity, in which each dimension has its specific meaning for personal self-identification and its own scale for assessing particular attributes.

In order to answer these questions qualitative data were gathered through participatory observations, a feed back survey, field study documentation and interviews from 47 system developers from a public authority. Our results suggest that field studies enhance the developer’s understanding of the user perspective, and provide a more holistic overview of the use situation, but that some developers were unable to interpret their observations and see solutions to the users’ problems. The field study method was very much appreciated and has now become standard operating procedure within the organization. However, although field studies may be useful, it does not replace the need for usability pro fes sion als, as their knowledge is essential for more complex observations, analysis and for keeping the focus on usability.

  11. Musical Sight-Reading Expertise: Cross Modality Investigations

    Full Text Available It is often said that expert musicians are capable of hearing what they read and vice versa. This suggests that they are able to process and to integrate multimodal information. The study investigates this issue with an eye-tracking technique. Two groups of musicians chosen on the basis of their level of expertise (expert and non-experts had to read excerpts of classical piano music and play them on a keyboard. In half the conditions, the participants heard the music before the reading phases. The excerpts contained suggested fingering of variable difficulty (difficult, easy, or no fingering. Analyses of first-pass fixation duration, second-pass fixation duration, probability of refixations, and playing mistakes validated the hypothesized modal independence of information among expert musicians as compared to non-experts. The results are discussed in terms of amodal memory for expert musicians, and they extend clearly our previous findings (Drai-Zerbib & Baccino, 2005. The talk will demonstrate that more experienced performers are better able to transfer learning from one modality to another, which can be in support of theoretical work by Ericsson and Kintsch (1995: more experienced performers better integrate knowledge across modalities. This view relies on the general flexibility shown in the experts' behaviour.

  12. A study of expertise effects for products with contradictory semantics

    2017-01-01

    Full Text Available In the design studies, researchers often use the semantic differential method with bipolar adjectives, such as “modern vs. classical” or “simple vs. complex” when investigating the semantics projected by product forms. However, in design practice, some design examples clearly exhibit the simultaneous use of contradictory meanings in product semantics. For example, retro car evokes nostalgia by borrowing characteristics from classical cars. At the same time it exhibits a modern style. However, most studies measure the product semantics mostly by using subjective measurement. There is lack objective measurement for that. In this research, we examined the results of applying the semantic differential method to measure contradiction in product semantics. The results showed that the distributions of semantic differential ratings for the stimuli with contradictory meanings have higher standard deviations. The sensitivity of semantic recognition may depend on participant expertise. The design experts are trained to be good at visual thinking that could easily identify the contradiction semantics between products. In general, successful embedding of contradictory meanings into product forms are based on simple, typical, and rational forms that can display complex, novel, and perceptual images by adding supplementary elements.

    Contemporary genomics research will impact the daily practice of biology teachers who want to teach up-to-date genetics in secondary education. This article reports on a research project aimed at enhancing biology teachers' expertise for teaching genetics situated in the context of genetic testing. The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of an educational approach based on situated learning. What expertise do biology teachers need for teaching genetics in the personal health context of genetic testing? This article describes the required expertise by exploring the educational practice. Nine experienced teachers were interviewed about the pedagogical content, moral and interpersonal expertise areas concerning how to teach genetics in the personal health context of genetic testing, and the lessons of five of them were observed. The findings showed that the required teacher expertise encompasses specific pedagogical content expertise, interpersonal expertise and a preference for teacher roles and teaching approaches for the moral aspects of teaching in this context. A need for further development of teaching and learning activities for (reflection on) moral reasoning came to the fore. Suggestions regarding how to apply this expertise into context-based genetics education are discussed.

    The Desmond Tutu Tuberculosis (TB) Centre (DTTC), Stellenbosch University, South Africa. 1) To determine whether access to designated funding is associated with the development of expertise in employees, and 2) which other factors are associated with the development of expertise in employees. This was a retrospective study. The target population consisted of all employees at the DTTC during the period 1 January 2004 to 31 December 2011. Improvement in expertise during employment was the primary outcome; the secondary outcome was an increase in educational level linked to the National Qualifications Framework. There was no association between access to funding and expertise development, but an association between the number of months employed and improvement of expertise during employment was observed (OR 1.03, 95%CI 1.02-1.04, P < 0.001), controlling for age at appointment, sex, access to designated funding and education level. The study shows that almost a third of employees increased their expertise, more than 90% had access to designated funding and personnel employed for a longer duration were more likely to experience improvements in expertise. We encourage research organisations in low- and middle-income countries to implement strategies to retain employees in order to build their expertise.

  6. Normal acquisition of expertise with greebles in two cases of acquired prosopagnosia

    Rezlescu, Constantin; Barton, Jason J. S.; Pitcher, David; Duchaine, Bradley

    2014-01-01

    Face recognition is generally thought to rely on different neurocognitive mechanisms than most types of objects, but the specificity of these mechanisms is debated. One account suggests the mechanisms are specific to upright faces, whereas the expertise view proposes the mechanisms operate on objects of high within-class similarity with which an observer has become proficient at rapid individuation. Much of the evidence cited in support of the expertise view comes from laboratory-based training experiments involving computer-generated objects called greebles that are designed to place face-like demands on recognition mechanisms. A fundamental prediction of the expertise hypothesis is that recognition deficits with faces will be accompanied by deficits with objects of expertise. Here we present two cases of acquired prosopagnosia, Herschel and Florence, who violate this prediction: Both show normal performance in a standard greeble training procedure, along with severe deficits on a matched face training procedure. Herschel and Florence also meet several response time criteria that advocates of the expertise view suggest signal successful acquisition of greeble expertise. Furthermore, Herschel’s results show that greeble learning can occur without normal functioning of the right fusiform face area, an area proposed to mediate greeble expertise. The marked dissociation between face and greeble expertise undermines greeble-based claims challenging face-specificity and indicates face recognition mechanisms are not necessary for object recognition after laboratory-based training.

  7. The contribution of research on expertise to understanding of expert thinking

    Directory of Open Access Journals (Sweden)

    Krnjaić Zora

    2013-01-01

    Full Text Available Expertise is determined based on the high level of mastery of knowledge and skills in different areas of human activities (science, art, sports and other less formal domains. This paper explores the contribution of empirical research on expertise to understanding of the nature of expert thinking. For that purpose we have compiled an overview and performed an analysis of the findings of relevant research on expertise based on different approaches and paradigms. We have included the studies that researched experts singled out based on their exceptional performances in different domains (absolute expertise and the studies based on comparing experts with novices (relative expertise. We have analyzed the studies using different paradigms: psychometric and cognitive paradigms, as well as the new offshoot, the paradigm based on viewing giftedness as developing expertise. Research results provide empirically grounded findings on the characteristics of expert thinking and consistently point to the fact that knowledge is the core of expertise. The characteristics of expert knowledge are operationalized via the quantity and organization of knowledge and the mastery of deep contents and knowledge systems, which enables the recognition of rules, models and information sets, as well as the use of knowledge in further studying, detecting and solving different problems. It can be concluded that research findings on expertise are one of the foundations in the conceptualization of expert thinking. They significantly contribute to obtaining an insight into the way in which knowledge shapes thought and into understanding the mechanisms of demonstrating knowledge in the mental processes of experts.

    Pang, C Y; Nadal, M; Müller-Paul, J S; Rosenberg, R; Klein, C

    2013-04-01

    This study investigated the electrocortical correlates of art expertise, as defined by a newly developed, content-valid and internally consistent 23-item art expertise questionnaire in N=27 participants that varied in their degree of art expertise. Participants viewed each 50 paintings, filtering-distorted versions of these paintings and plain colour stimuli under free-viewing conditions whilst the EEG was recorded from 64 channels. Results revealed P3b-/LPC-like bilateral posterior event-related potentials (ERP) that were larger over the right hemisphere than over the left hemisphere. Art expertise correlated negatively with the amplitude of the ERP responses to paintings and control stimuli. We conclude that art expertise is associated with reduced ERP responses to visual stimuli in general that can be considered to reflect increased neural efficiency due to extensive practice in the contemplation of visual art.

    2016-03-01

    Studies of event-related potentials show that the specific N170 response has become a stable electrophysiological hallmark of objects related to expertise in early perceptual processing. In the present study, we investigated whether eyeglasses can elicit N170 effects similar to those elicited by objects of expertise. Our results showed that the N170 response elicited by eyeglasses was larger than the response elicited by objects that do not generate perceptual expertise (e.g., houses). Importantly, we found that eyeglasses could produce a within-category N170 adaptation effect, similar to that produced in response to objects of expertise (e.g., faces). Our results have revealed for the first time that with a large amount of experience, eyeglasses could evoke the face-like N170 response, which suggested that eyeglasses may become an object of perceptual expertise to some human observers.

  12. The Global Professional

    Directory of Open Access Journals (Sweden)

    Gilles Bousquet

    2005-01-01

    Full Text Available As educators in an increasingly global society, we realize that we need to train students-undergraduate and graduate-to live and work in a global environment. This idea is not a new one; scholars, administrators, and government officials have been promoting similar notions for several decades, especially since the advent of the Cold War. David Ward, president of the American Council on Education, emphasized at the 2003 annual meeting of the National Association of State Universities and Land Grant Colleges that international education can no longer be considered "business as usual." The concept that graduates must have cross-cultural knowledge and expertise -long recognized in the languages and humanities-has steadily gained support to become an important goal and a marker of achievement for many professional schools in the United States today.

  13. Musical expertise modulates early processing of syntactic violations in language

    Directory of Open Access Journals (Sweden)

    Ahren B. Fitzroy

    2013-01-01

    Full Text Available Syntactic violations in speech and music have been shown to elicit an anterior negativity (AN as early as 100 ms after violation onset and a posterior positivity that peaks at roughly 600 ms (P600/LPC. The language AN is typically reported as left-lateralized (LAN, whereas the music AN is typically reported as right-lateralized (RAN. However, several lines of evidence suggest syntactic processing of language and music rely on overlapping neural systems. The current study tested the hypothesis that syntactic processing of speech and music share neural resources by examining whether musical proficiency modulates ERP indices of linguistic syntactic processing. ERPs were measured in response to syntactic violations in sentences and chord progressions in musicians and nonmusicians. Violations in speech were insertion errors in normal and semantically impoverished English sentences. Violations in music were out-of-key chord substitutions from distantly and closely related keys. Phrase-structure violations elicited an AN and P600 in both groups. Harmonic violations elicited an LPC in both groups, blatant harmonic violations also elicited a RAN in musicians only. Cross-domain effects of musical proficiency were similar to previously reported within-domain effects of linguistic proficiency on the distribution of the language AN; syntactic violations in normal English sentences elicited a left-lateralized AN in musicians and a bilateral AN in nonmusicians. The late positivities elicited by violations differed in latency and distribution between domains. These results suggest that initial processing of syntactic violations in language and music relies on shared neural resources in the general population, and that musical expertise results in more specialized cortical organization of syntactic processing in both domains.

  14. Building expertise in glaciology through intense international summer schools

    Science.gov (United States)

    Hock, R.

    2016-12-01

    As the field of glaciology grows in response to recent rapid glacier changes and their potential socio-environmental consequences, the need for well-trained scientists possessing a high level expertise in physical glaciology has increased. Opportunities necessary to cultivate these efforts have not kept pace with the need for increased proficiency in this field. To our knowledge there is no academic degree in glaciology anywhere, but glaciology education, if offered at all, is generally restricted to one or a few individual classes. Glaciology graduate students tend to come from a wide range of background education and often pursue their degree at institutes without any glaciology classes. To cater to this demand we have organized four intense 11-day International Summer Schools in Glaciology which have provided an opportunity for a total of 119 students from around the world to obtain a comprehensive insight into a wide range of topics in glaciology and a more holistic view beyond the scope of their graduate thesis topic. The summer schools were held bi-annually (2010 - 2016) in the tiny village of McCarthy in central Alaska in the immediate vicinity of easily accessible glaciers. The unique setting facilitated close interaction among all participants. The courses included daily lectures, computational exercises, a poster-session and two glacier excursions. In addition, students worked in small teams on a glaciology computer project mentored by one of the 7-9 instructors from several US and foreign institutions, and presented their results in a `mini' student conference at the end of the course. All instructors were required to stay for the entire period. Thus the courses provided a valuable platform for international networking between students and instructors and among the students themselves, thereby fostering future collaborations. This was generally perceived as a major asset of our summer schools.

  15. Both novelty and expertise increase action observation network activity

    2013-09-01

    Full Text Available Our experiences with others affect how we perceive their actions. In particular, activity in bilateral premotor and parietal cortices during action observation, collectively known as the action observation network (AON, is modulated by one’s expertise with the observed actions or individuals. However, conflicting reports suggest that AON activity is greatest both for familiar and unfamiliar actions. The current study examines the effects of different types and amounts of experience (e.g., visual, interpersonal, personal on AON activation. fMRI was used to scan 16 healthy participants without prior experience with individuals with amputations (novices, 11 experienced occupational therapists (OTs who had varying amounts of experience with individuals with amputations, and one individual born with below-elbow residual limbs (participant CJ, as they viewed video clips of goal-matched actions performed by an individual with residual limbs and by an individual with hands. Participants were given increased visual exposure to actions performed by both effectors midway through the scanning procedure. Novices demonstrated a large AON response to the initial viewing of an individual with residual limbs compared to one with hands, but this signal was attenuated after they received visual exposure to both effectors. In contrast, OTs, who had moderate familiarity with residual limbs, demonstrated a lower AON response upon initial viewing—similar to novices after they received visual exposure. At the other extreme, CJ, who has extreme familiarity with residual limbs both visually and motorically, shows a largely increased left-lateralized AON response, exceeding that of novices and experienced OTs, when viewing the residual limb compared to hand actions. These results suggest that a nuanced model of AON engagement is needed to explain how cases of both extreme experience (CJ and extreme novelty (novices can result in the greatest AON activity.

    Full Text Available It is often said that experienced musicians are capable of hearing what they read (and vice versa. This suggests that they are able to process and to integrate multimodal information. The study investigates this issue with an eye-tracking technique. Two groups of musicians chosen on the basis of their level of expertise (experts, non-experts had to read excerpts of poorly-known classical piano music and play them on a keyboard. The experiment was run in two consecutive phases during which each excerpt was (1 read without playing and (2 sight-read (read and played. In half the conditions, the participants heard the music before the reading phases. The excerpts contained suggested fingering of variable difficulty (difficult, easy, or no fingering. Analyses of first-pass fixation duration, second-pass fixation duration, probability of refixations, and playing mistakes validated the hypothesized modal independence of information among expert musicians as compared to non-experts. The results are discussed in terms of amodal memory for expert musicians, and they extend clearly our previous findings (Drai-Zerbib & Baccino, 2005. The paper will demonstrate that more experienced performers are better able to transfer learning from one modality to another, which can be in support of theoretical work by Ericsson and Kintsch (1995: more experienced performers better integrate knowledge across modalities. This view relies on the general flexibility shown in the experts' behaviour. The paper will show the correspondence between our results and issues recently obtained in ERPs researches and brain imaging studies (fMRI, MEG, where cerebral structures generally associated with different perceptual modalities were shown to be interconnected or overlap.

    Full Text Available Dans cet article, on discute la spécificité de la "participation" des citoyens dans les cas de délibération sur l'acceptation du risque nucléaire, montrant que cette participation dépend de la médiation d'un professionnel capable de traduire le jargon scientifique des documents techniques ou établissant lui-même ses propres documents, à titre de contre-expertise; sinon, les profanes ne sauront légitimer leurs arguments scientifiquement. Dans ce travail, on prend comme base empirique les thèmes récurrents des audiences publiques organisées en vue du permis de fonctionnement des deux centrales nucléaires brésiliennes de technologie allemande - Angra 2 et Angra 3 -, surtout pour cette dernière, en cours de licence environnementale préalable.

  1. L’analyse du risque alimentaire : quels principes, quels modèles, quelles organisations pour demain ?

    Directory of Open Access Journals (Sweden)

    Chevassus-au-Louis Bernard

    2001-07-01

    Full Text Available Jusqu’à une époque récente, les structures d’expertise des pays développés ont réalisé leur travail d’analyse du risque sanitaire des aliments selon un modèle « standard », élaboré pour l’analyse d’autres risques technologiques et dont nous rappellerons tout d’abord les caractéristiques et les principales options. Depuis le début des années 80, l’observation d’un certain nombre de dysfonctionnements dans la chaîne de l’alimentation a suscité dans l’opinion publique de plusieurs pays un scepticisme croissant sur la valeur de ce modèle. Le principe de précaution a donc été proposé comme un nouveau fil conducteur pour améliorer l’analyse du risque alimentaire. Nous en présenterons tout d’abord les conséquences sur la gestion du risque, en nous basant sur la définition « proportionnée » du principe de précaution qui émerge actuellement en Europe. Nous remonterons ensuite au niveau de l’évaluation des risques, pour montrer comment les nouvelles demandes des gestionnaires pour une bonne application du principe de précaution ont des conséquences importantes sur la démarche d’évaluation elle-même. Enfin, nous interrogerons la vision « standard » de la communication du risque, conçue comme la dernière phase du processus d’analyse de risque. Nous montrerons en quoi une contribution active de représentants de la société civile dès les phases d’évaluation et de gestion peut permettre à la fois d’améliorer la qualité et l’acceptabilité de l’analyse de risque. L’application du principe de précaution a donc des conséquences non pas sur une seule mais sur les trois phases de l’analyse du risque. L’ensemble de ces modifications permet de proposer un modèle alternatif, dit « constructiviste », qui, dans le cas du risque alimentaire, peut contribuer à une meilleure acceptabilité par la société des rares, mais inévitables, dysfonctionnements de la production de

    Jan Gube

    2017-01-01

    Full Text Available Aim/Purpose: This paper considers the role of supervisors’ discipline expertise in doctoral learning from a student perspective. Background:\tDoctoral students need to develop expertise in a particular field of study. In this context, developing expertise requires doctoral students to master disciplinary knowledge, conventions and scholarship under the guidance of supervisors. Methodology\t: The study draws on a mixed-method approach, using an online survey and semi-structured interviews conducted with doctoral students. Contribution: The paper brings to the fore the role of supervisors’ discipline expertise on doctoral students’ research progress. Findings: The survey data suggest that doctoral students nominate their supervisors on the basis of their discipline expertise. They also view supervisors’ expertise as key to the development of ‘insider’ knowledge of their doctoral research. Recommendations for Practitioners: Supervisors play a pivotal role in helping doctoral students overcome intellectual barriers by imparting their discipline knowledge as well as balancing satisfactory doctoral completion rate and high quality student experience. Impact on Society\t: Doctoral supervision equips doctoral students with the right arsenal to be able to competently operate within their field and prepares them for their future research or professional career that demands a high level of discipline expertise. Future Research:\tThe scope of the findings leaves open a discussion about the experiences of doctoral students matched with non-discipline expert supervisory teams; for example, the extent of the mismatch and its ramifications.

  8. Two Troubling Trends in the Conversation Over Whether Clinical Ethics Consultants Have Ethics Expertise.

    Science.gov (United States)

    Brummett, Abram; Ostertag, Christopher J

    2017-04-18

    In a recent issue of the Journal of Medicine and Philosophy, several scholars wrote on the topic of ethics expertise in clinical ethics consultation. The articles in this issue exemplified what we consider to be two troubling trends in the quest to articulate a unique expertise for clinical ethicists. The first trend, exemplified in the work of Lisa Rasmussen, is an attempt to define a role for clinical ethicists that denies they have ethics expertise. Rasmussen cites the dependence of ethical expertise on irresolvable meta-ethical debates as the reason for this move. We argue against this deflationary strategy because it ends up smuggling in meta-ethical assumptions it claims to avoid. Specifically, we critique Rasmussen's distinction between the ethical and normative features of clinical ethics cases. The second trend, exemplified in the work of Dien Ho, also attempts to avoid meta-ethics. However, unlike Rasmussen, Ho tries to articulate a notion of ethics expertise that does not rely upon meta-ethics. Specifically, we critique Ho's attempts to explain how clinical ethicists can resolve moral disputes using what he calls the "Default Principle" and "arguments by parity." We show that these strategies do not work unless those with the moral disagreement already share certain meta-ethical assumptions. Ultimately, we argue that the two trends of (1) attempting to avoid meta-ethics by denying that clinical ethicists have ethics expertise, and (2) attempting to articulate how ethics expertise can be used to resolve disputes without meta-ethics both fail because they do not, in fact, avoid doing meta-ethics. We conclude that these trends detract from what clinical ethics consultation was founded to do and ought to still be doing-provide moral guidance, which requires ethics expertise, and engagement with meta-ethics. To speak of ethicists without ethics expertise leaves their role in the clinic dangerously unclear and unjustified.

    Pourquoi l'Univers plutôt que le vide ? Le temps et l'espace existent-ils en l'absence de l'Univers ? Que reste-t-il quand tout est enlevé ? Pourquoi quelque chose plutôt que rien ? Depuis des siècles, ces interrogations mobilisent philosophes et physiciens. Mais aujourd'hui, le vide n'est pas le rien. Il serait même l'acteur central de l'histoire de la matière et de l'Univers, le partenaire privilégié de la physique. Vide et matière ne sont plus deux manifestations séparées de la nature, mais deux aspects d'une même réalité. Le vide est l'état de base dont la matière émerge, sans couper son cordon ombilical Le vide comme Univers du rien cède la place au vide comme Univers du tout. Que le vide puisse être conçu par les physiciens comme réservoir potentiel d'univers, voici qui ne devrait laisser personne indifférent. Ce livre ouvre un débat et nous convie à une réflexion surprenante.

  1. Field Studies—Essential Cognitive Foundations for Geoscience Expertise

    Science.gov (United States)

    Goodwin, C.; Mogk, D. W.

    2010-12-01

    Learning in the field has traditionally been one of the fundamental components of the geoscience curriculum. Field experiences have been attributed to having positive impacts on cognitive, affective, metacognitive, mastery of skills and social components of learning geoscience. The development of geoscience thinking, and of geoscience expertise, encompasses a number of learned behaviors that contribute to the progress of Science and the development of scientists. By getting out into Nature, students necessarily engage active and experiential learning. The open, dynamic, heterogeneous and complex Earth system provides ample opportunities to learn by inquiry and discovery. Learning in this environment requires that students make informed decisions and to think critically about what is important to observe, and what should be excluded in the complex overload of information provided by Nature. Students must learn to employ the full range of cognitive skills that include observation, description, interpretation, analysis and synthesis that lead to “deep learning”. They must be able to integrate and rationalize observations of Nature with modern experimental, analytical, theoretical, and modeling approaches to studying the Earth system, and they must be able to iterate between what is known and what is yet to be discovered. Immersion in the field setting provides students with a sense of spatial and temporal scales of natural phenomena that can not be derived in other learning environments. The field setting provides strong sensory inputs that stimulate cognition and memories that will be available for future application. The field environment also stimulates strong affective responses related to motivation, curiosity, a sense of “ownership” of field projects, and inclusion in shared experiences that carry on throughout professional careers. The nature of field work also contains a strong metacognitive component, as students learn to be aware of what and how they

  6. Expertise with artificial nonspeech sounds recruits speech-sensitive cortical regions.

    Science.gov (United States)

    Leech, Robert; Holt, Lori L; Devlin, Joseph T; Dick, Frederic

    2009-04-22

    Regions of the human temporal lobe show greater activation for speech than for other sounds. These differences may reflect intrinsically specialized domain-specific adaptations for processing speech, or they may be driven by the significant expertise we have in listening to the speech signal. To test the expertise hypothesis, we used a video-game-based paradigm that tacitly trained listeners to categorize acoustically complex, artificial nonlinguistic sounds. Before and after training, we used functional MRI to measure how expertise with these sounds modulated temporal lobe activation. Participants' ability to explicitly categorize the nonspeech sounds predicted the change in pretraining to posttraining activation in speech-sensitive regions of the left posterior superior temporal sulcus, suggesting that emergent auditory expertise may help drive this functional regionalization. Thus, seemingly domain-specific patterns of neural activation in higher cortical regions may be driven in part by experience-based restructuring of high-dimensional perceptual space.

    Full Text Available L’expertise médico-légale n’est pas une création du XIXe siècle mais l’application du Code pénal napoléonien de 1810 va profondément modifier la place des experts dans le débat judiciaire. Face à certains comportements étranges, les juges seront amenés à solliciter de plus en plus fréquemment les experts psychiatres afin de déterminer le niveau de responsabilité imputable aux auteurs de crimes ou délits. Dans le domaine spécifique des infractions sexuelles, il reviendra aux psychiatres de déterminer la limite entre la perversité et la perversion, le partage entre la sanction et le soin. Malgré un souci croissant de scientificité présent dans les études médicales consacrées aux perversions sexuelles, les experts psychiatres du XIXe siècle n’arriveront pas toujours à se déprendre des valeurs politiques et morales dominantes de leur temps.Medico-legal expertise was not a creation of the 19th century but application of the Napoleonic Criminal Code of 1810 profoundly changed the role of experts in judicial proceedings. Faced with certain strange behaviors, judges were increasingly led to solicit psychiatric experts so as to determine the level of responsibility attributable to those accused of crimes or misdemeanors. In the specific domain of sexual offenses, it fell to psychiatrists to determine the border between perversity and perversion, and the distinction between sanction and care.  In spite of growing concern with the scientific character of medical studies devoted to sexual perversions, psychiatric experts of the 19th century did not always succeed in separating themselves from the dominant political and moral values of their times.

    Managing personal aspects of health is challenging for many patients, particularly those facing a serious condition such as cancer. Finding experienced patients, who can share their knowledge from managing a similar health situation, is of tremendous value. Users of health-related social software form a large base of such knowledge, yet these tools often lack features needed to locate peers with expertise. Informed directly by our field work with breast cancer patients, we designed a patient expertise locator for users of online health communities. Using feedback from two focus groups with breast cancer survivors, we took our design through two iterations. Focus groups concluded that expertise locating features proved useful for extending social software. They guided design enhancements by suggesting granular user control through (1) multiple mechanisms to identify expertise, (2) detailed user profiles to select expertise, and (3) varied collaboration levels. Our user-centered approach links field work to design through close collaboration with patients. By illustrating trade-offs made when sharing sensitive health information, our findings inform the incorporation of expertise locating features into social software for patients.

  17. Semantic and Time-Dependent Expertise Profiling Models in Community-Driven Knowledge Curation Platforms

    Full Text Available Online collaboration and web-based knowledge sharing have gained momentum as major components of the Web 2.0 movement. Consequently, knowledge embedded in such platforms is no longer static and continuously evolves through experts’ micro-contributions. Traditional Information Retrieval and Social Network Analysis techniques take a document-centric approach to expertise modeling by creating a macro-perspective of knowledge embedded in large corpus of static documents. However, as knowledge in collaboration platforms changes dynamically, the traditional macro-perspective is insufficient for tracking the evolution of knowledge and expertise. Hence, Expertise Profiling is presented with major challenges in the context of dynamic and evolving knowledge. In our previous study, we proposed a comprehensive, domain-independent model for expertise profiling in the context of evolving knowledge. In this paper, we incorporate Language Modeling into our methodology to enhance the accuracy of resulting profiles. Evaluation results indicate a significant improvement in the accuracy of profiles generated by this approach. In addition, we present our profile visualization tool, Profile Explorer, which serves as a paradigm for exploring and analyzing time-dependent expertise profiles in knowledge-bases where content evolves overtime. Profile Explorer facilitates comparative analysis of evolving expertise, independent of the domain and the methodology used in creating profiles.

In the first study, we show that performance in the popular MOBA League of Legends' correlates with fluid intelligence as measured under controlled laboratory conditions. In the second study, we also show that the age profile of performance in the two most widely-played MOBAs (League of Legends and DOTA II matches that of raw fluid intelligence.

    2015-03-01

    Full Text Available This contribution investigates the strategies that environmental agencies develop to enhance their policy autonomy, in order to fulfil their organisational missions for protecting the environment. This article asks whether there are particular strategic moves that an agency can make to augment this policy autonomy in the face of the principals. Critiquing principal agent theory, it investigates the evolution of three environmental agencies (the European Environment Agency, the England and Wales Environment Agency and the United States Environmental Protection Agency, focusing on the case study of climate change. The contribution examines how the agencies influence environmental policy on domestic, regional and global levels, with a special focus on the principals that constrain agency autonomy. A greater focus on different multi-level contexts, which the three agencies face, may create other possible dynamics and opportunities for agency strategies. Agencies can use particular knowledge, network and alliance building to strengthen their policy/political positions.

    The law from December 30, 1991, precisely defines 3 axes of researches for the management of high level and long-lived radioactive wastes: separation/transmutation, surface storage and underground disposal. A global evaluation report about these researches is to be supplied in 2006 by the French government to the Parliament. A first synthesis of the knowledge gained after 14 years of research has led the national commission of the public debate (CNDP) to organize a national debate about the general options of management of high-level and long-lived radioactive wastes before the 2006 date line. The debate comprises 4 public hearings (September 2005: Bar-le-Duc, Saint-Dizier, Pont-du-Gard, Cherbourg), 12 round-tables (October and November 2005: Paris, Joinville, Caen, Nancy, Marseille), a synthesis meeting (December 2005, Dunkerque) and a closing meeting (January 2006, Lyon). This document is the synthesis of the debates of the third public hearing at Pont-du-Gard. This meeting gathers representatives of the different actors of the nuclear industry, ministers, public authorities, non governmental organizations who argue the questions asked by peoples from the audience. The topics concern the nuclear energy and industry in general and the problems of waste management in particular. A presentation (slides) of the structure of PWR's spent fuels is attached to the proceedings. (J.S.)

    The Baume du commandeur appears in Franch in 1694 in the Histoire générale des drogues [...] written by Pomet. It's a vulnerary drug with also numerous internal uses. Still present in formularies and sometimes used, its invention is attributed to Gaspard de Pernes, commander of Malta Order in Toul, in France. However, some observations induce us to think that the origin of this drug would be in eastern countries: first one of its other names, baume persique, secondly the name of a comparable other formula baume des Turcs, then the geographical origin of the majority of plants and drugs constituting the initially published formula, finally the appurtenance of G. de Pernes to Malta Order. Unfortunately, the transmissions, modifications and improvements of the formula since its beginning make today very difficult to discover the localization and dating of the creation of this famous drug.

  12. Changing the meaning of peer-to-peer? Exploring online comment spaces as sites of negotiated expertise

    Directory of Open Access Journals (Sweden)

    Marie-Claire Shanahan

    2010-02-01

    Full Text Available This study examines the nature of peer-to-peer interactions in public online comment spaces. From a theoretical perspective of boundary-work and expertise, the comments posted in response to three health sciences news articles from a national newspaper are explored to determine whether both scientific and personal expertise are recognized and taken up in discussion. Posts were analysed for both explicit claims to expertise and implicit claims embedded in discourse. The analysis suggests that while both scientific and personal expertise are proffered by commenters, it is scientific expertise that is privileged. Those expressing scientific expertise receive greater recognition of the value of their posts. Contributors seeking to share personal expertise are found to engage in scientisation to position themselves as worthwhile experts. Findings suggest that despite the possibilities afforded by online comments for a broader vision of what peer-to-peer interaction means, this possibility is not realized.

    Previous research into the effects of action video gaming on cognition has suggested that long term exposure to this type of game might lead to an enhancement of cognitive skills that transfer to non-gaming cognitive tasks. However, these results have been controversial. The aim of the current study was to test the presence of positive cognitive transfer from action video games to two cognitive tasks. More specifically, this study investigated the effects that participants' expertise and genre specialization have on cognitive improvements in one task unrelated to video gaming (a flanker task) and one related task (change detection task with both control and genre-specific images). This study was unique in three ways. Firstly, it analyzed a continuum of expertise levels, which has yet to be investigated in research into the cognitive benefits of video gaming. Secondly, it explored genre-specific skill developments on these tasks by comparing Action and Strategy video game players (VGPs). Thirdly, it used a very tight experiment design, including the experimenter being blind to expertise level and genre specialization of the participant. Ninety-two university students aged between 18 and 30 (M = 21.25) were recruited through opportunistic sampling and were grouped by video game specialization and expertise level. While the results of the flanker task were consistent with previous research (i.e., effect of congruence), there was no effect of expertise, and the action gamers failed to outperform the strategy gamers. Additionally, contrary to expectation, there was no interaction between genre specialization and image type in the change detection task, again demonstrating no expertise effect. The lack of effects for game specialization and expertise goes against previous research on the positive effects of action video gaming on other cognitive tasks.

  7. The expertise required for greenhouse gas assurance engagements: Lessons to be learned from existing schemes and standards

    2009-07-01

    The worldwide pressure for reporting entities to disclose their greenhouse gas (GHG) emissions is increasing as emissions trading schemes (ETS) emerge as the preferred government response to the global challenge of climate change. The demand for assurance of GHG emissions disclosures under such schemes is increasing concomitantly. The benefits of having GHG disclosures independently assured have been identified and include the increased confidence that can be placed on the information for decision-making purposes. Significantly, unlike financial statement audit engagements, assurance engagements on GHG emissions are commonly undertaken by practitioners outside the accounting profession including professional engineers and environmental scientists. This raises issues for government regulators and standard-setters to draft requirements that can apply to GHG emissions assurance providers from a range of disciplines and backgrounds. This paper examines how existing regulatory-based ETSs throughout the world have attempted to implement quality controls to address appropriate skills and competencies for GHG assurance providers. It further explores the treatment of team expertise and composition issues in the draft International Standard on Assurance Engagements (ISAE) 3410 'Assurance on a Greenhouse Gas Statement' being developed by the International Auditing and Assurance Standards Board (IAASB). As such, this paper informs the debate on expertise for GHG assurance engagements and best practice for regulations and assurance standards in this area. For the purposes of this paper, regulation of, or guidance for, GHG assurance providers related to the European Union Emissions Trading Scheme (EU ETS), the North American Regional Greenhouse Gas Initiative (RGGI), Alberta's Climate Change and Emissions Management Act (the Alberta Scheme), Australia's National Greenhouse and Energy Reporting Act (the NGER scheme) and the New South Wales Greenhouse Gas

    Gamblers who participate in skill-oriented games (such as poker and sports-betting) are motivated to win over the long-term, and some monitor their betting outcomes to evaluate their performance and proficiency. In this study of Australian off-track horserace betting, we investigated which levels of sustained returns would be required to establish evidence of skill/expertise. We modelled a random strategy to simulate 'naïve' play, in which equal bets were placed on randomly selected horses using a representative sample of 211 weekend races. Results from a Monte Carlo simulation yielded a distribution of return-on-investments for varying number of bets (N), showing surprising volatility, even after a large number of repeated bets. After adjusting for the house advantage, a gambler would have to place over 10,000 bets in individual races with net returns exceeding 9 % to be reasonably considered an expert punter (α = .05). Moreover, a record of fewer bets would require even greater returns for demonstrating expertise. As such, validated expertise is likely to be rare among race bettors. We argue that the counter-intuitively high threshold for demonstrating expertise by tracking historical performance is likely to exacerbate known cognitive biases in self-evaluation of expertise.

  9. Driven by Expertise and Insulation? The Autonomy of European Regulatory Agencies

    Full Text Available Expertise and autonomy are cornerstones to the effective operation and legitimacy of European Regulatory Agencies (ERAs. Yet, we know little about ERAs’ actual autonomy, nor about factors shaping it. This article studies ERAs’ actual autonomy from public and private actors, emphasising two crucial explanatory factors: expertise and rulemaking competences. The lack of insights on expertise is particularly striking, as expertise—the “raison d’être” and main resource of expert bodies—provides ERAs with a potentially powerful means to increase autonomy. Relying on a rational institutionalist framework within which ERAs enjoy substantive discretion to pursue their goals, the study empirically compares three powerful ERAs—the European Medicines Agency, the European Chemicals Agency, and the European Food Safety Authority. Based on the analysis of 39 semi-structured expert interviews, findings show that expertise is a crucial explanation for ERAs’ substantive autonomy from the Commission. Towards research intensive private stakeholders, the role of expertise becomes less pronounced. Instead, ERAs are more successful in protecting their autonomy by engaging in the risk-averse interpretation of the regulatory framework and by adapting rules over time to adapt their needs: they engage in “procedural insulation”. Political salience provides a scope condition for ERAs to use expert knowledge and rulemaking competences more strategically—potentially undermining scientific quality.

    Expertise is characterized by fast decision-making which is highly adaptive to new situations. Here we propose that athletes use a toolbox of heuristics which they develop on their route to expertise. The development of heuristics occurs within the context of the athletes' natural abilities, past experiences, developed skills, and situational context, but does not pertain to any of these factors separately. This is a novel approach because it integrates separate factors into a comprehensive heuristic description. The novelty of this approach lies within the integration of separate factors determining expertise into a comprehensive heuristic description. It is our contention that talent identification methods and talent development models should therefore be geared toward the assessment and development of specific heuristics. Specifically, in addition to identifying and developing separate natural abilities and skills as per usual, heuristics should be identified and developed. The application of heuristics to talent and expertise models can bring the field one step away from dichotomized models of nature and nurture toward a comprehensive approach to the route to expertise.

    Little is known about how APOE ε4-related differences in cognitive performance translate to real-life performance, where training and experience may help to sustain performance. We investigated the influences of APOE ε4 status, expertise (FAA pilot proficiency ratings), and their interaction on longitudinal flight simulator performance. Over a 2-year period, 139 pilots aged 42–69 years were tested annually. APOE ε4 carriers had lower memory performance than noncarriers (p = .019). APOE interacted with Expertise (p = .036), such that the beneficial influence of expertise (p = .013) on longitudinal flight simulator performance was more pronounced for ε4 carriers. Results suggest that relevant training and activity may help sustain middle-aged and older adults’ real-world performance, especially among APOE ε4 carriers. PMID:21668123

    Both speech and music are constituted by sequences of sound elements that unfold in time and require listeners to engage cognitive functions such as sequencing, attention, and memory. We recently ran a set of experiments with the aim of testing the effect of musical expertise on a rather high cognitive function: speech segmentation. Here, we will present the main concepts underlying the investigation of speech segmentation as well as its link to music and musical expertise. Interestingly, our results seem to show that musical training and expertise have effects on brain plasticity that may go beyond primary regions. Moreover, to facilitate and improve future research in this domain, we will here describe several delicate methodological precautions that need to be taken into account (e.g., the choice of stimuli, participants, data analyses). Finally, we will give some possible future directions to better understand the impact that music may have on speech processing. © 2012 New York Academy of Sciences.

Extrajudicial execution suggests that it falls outside the realm of legality. This article does not seek to settle which terminology is the most appropriate. Instead it analyses...... the legal expertise struggling to do so and its implications. More specifically, it focuses on the processes through which drones constitute the legal expertise that constitutes the drone program as one of targeted killings and of extrajudicial executions; that is, on a process of co-constitution. Drawing...... theoretical inspiration from and combining new materialist approaches (especially as articulated by Bruno Latour) with the sociological approach of Pierre Bourdieu, the article shows that drones have 'agency' in the 'field' of legal expertise pertaining to the drone program.

  18. The style of a stranger: Identification expertise generalizes to coarser level categories.

    Searston, Rachel A; Tangen, Jason M

    2017-08-01

    Experience identifying visual objects and categories improves generalization within the same class (e.g., discriminating bird species improves transfer to new bird species), but does such perceptual expertise transfer to coarser category judgments? We tested whether fingerprint experts, who spend their days comparing pairs of prints and judging whether they were left by the same finger or two different fingers, can generalize their finger discrimination expertise to people more broadly. That is, can these experts identify prints from Jones's right thumb and prints from Jones's right index finger as instances of the same "Jones" category? Novices and experts were both sensitive to the style of a stranger's prints; despite lower levels of confidence, experts were significantly more sensitive to this style than novices. This expert advantage persisted even when we reduced the number of exemplars provided. Our results demonstrate that perceptual expertise can be flexible to upwards shifts in the level of specificity, suggesting a dynamic memory retrieval process.

  20. In Respect to the Cognitive Load Theory: Adjusting Instructional Guidance with Student Expertise.

    2017-01-01

    The amount of guidance supplied by educators to students in allied health programs is a factor in student learning. According to the cognitive load theory of learning, without adequate instructional support, novice learners will be overwhelmed and unable to store information, while unnecessary guidance supplied to advanced students will cause extraneous cognitive load on the working memory system. Adjusting instructional guidance for students according to their level of expertise to minimize extraneous cognitive load and optimize working memory storage capacity will enhance learning effectiveness. Novice students presented with complex subject matter require significant guidance during the initial stages, using strategies such as worked examples. As students comprehend information, instructional guidance needs to gradually fade to avoid elevated extraneous cognitive load from the expertise reversal effect. An instructional strategy that utilizes a systemic (fixed) or adjustable (adaptive) tapering of guidance to students in allied health programs depending on their expertise will optimize learning capability.

    The first five years of parenting are critical to children's development. Parents are known to respond best to interventions with a partnership-based approach, yet child and family health nurses (CFHNs) report some tension between employing their expertise and maintaining a partnership relationship. This article identifies ways in which CFHNs skilfully use their professional expertise, underpinned by helping qualities and interpersonal skills, to assist families build confidence and capacity, and thus buffer against threats to parent and child well-being. It reports on an Australian ethnographic study of services for families with young children. Fifty-two interactions were observed between CFHNs and families in day-stay and home visiting services in Sydney. A new model is presented, based on four partnership activities and the fluid movement between them, to show how CFHNs use their expertise to identify strengths and foster resilience in families in the longer term, without undermining the principles of partnership.

    2012-01-01

    The cri du chat syndrome (CdCS) is a chromosomal deletion syndrome associated with a partial deletion of the short (p) arm of chromosome 5. We describe five children who were diagnosed to have CdCS by conventional cytogenetic analysis. The deletion was at 5p15 in four patients, whereas the fifth had a larger, more proximal deletion at 5p14. Fluorescence in situ hybridization (FISH) analysis confirmed the deletion of the CdCS critical region at 5p15.2. All five children had global developmental delay and dysmorphism with microcephaly. The other clinical features were variable. Since the clinical diagnosis of CdCS may not always be evident because of the phenotypic heterogeneity, cytogenetic analysis is necessary to establish the diagnosis and confirm that the deletion involves the CdCS critical region. This will enable early intervention which plays an important role in improving the outcome.
