    The expertise realized by the INRA relatives the interest of storage carbon in agricultural soils in France: if the possibility of storage is not inconsiderable, its valorization in the framework of the Kyoto protocol is difficult. This storage should be considered in a broader framework, including all the greenhouse gases and integrated in a global plan on the sustainable agriculture and soils quality. (A.L.B.)

  5. 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.

    In a context of development of new technologies of wireless communications, and therefore of radio-electric signals used to transmit information, this voluminous document reports a detailed study on the effects of radiofrequency on health. It is notably based on a large literature survey and on an assessment of the level of proof of these effects by experts (proved, possible, probable, insufficiently proved, or no effect on mankind). These effects can be either biological or on health. The report presents the context, scope and modalities of the expertise study, presents the main artificial and natural sources of radiofrequency radiation, gives a detailed presentation of new exposure sources (new signals, new radio-electric networks and their applications like mobile phones, pads, mobile television, local wireless networks, RFID, so on). It describes metrology and dose measurement techniques for electromagnetic fields (exposure characterization in laboratory, characterization of the electromagnetic environment, individual exposure measurement devices, digital dosimetry). It addresses the efficiency of anti-wave devices. The next part presents the literature survey (method, analysis, results). The authors then report an assessment of the risk level related to radio-frequencies for the central nervous system (neurotoxicity mechanisms, cognitive functions, memory and behaviour, sleep and circadian rhythms, hearing functions, neurological and neuro-degenerative diseases), and an assessment of the risk level of radio-frequencies for other non-carcinogenic effects (possible mechanisms, reproduction, immunology, endocrine system, and so on). They discuss the researches on potential carcinogenic mechanisms. They give an overview of the evolutions of regulations and management measures in France, and propose a set of recommendations

  10. A Cafe Scientifique for Teens

    Science.gov (United States)

    Hall, M.; Mayhew, M.

    2008-12-01

    It is well-known to those pursuing the quest to connect scientists to the public that an exceedingly hard-to- reach demographic is people of high school age. Typically, kids may tag along with their parents to museums until they reach adolescence, and then don't again appear in museums until they themselves have children. We have addressed this demographic challenge for free-choice-learning by developing a Cafe Scientifique program specifically for high school students. The Cafe Scientifique model for adults was developed in England and France, and has now spread like wildfire across the U.S. Typically, people come to a informal setting like a cafe, socialize and have food and drink, and then hear a short presentation by a scientist on a hot science topic in the news. This is followed by a period of lively discussion. We have followed this model for high school age students in four towns in northern New Mexico--Los Alamos, Santa Fe, Espanola, and Albuquerque--which represent a highly diverse demographic. We started this novel project with some trepidation, i.e. what if we build it and they don't come. But the program has proven popular beyond our expectations in all four towns. A part of the secret of success is the social setting, and-especially for this age group-the food provided. But we have also found that the kids are genuinely interested in the science topics, directing their own program, and interacting with scientists. We have often heard statements like, "I think it is important to be well-informed citizens". One of the most important aspects of the Cafes for the kids is to be able to discuss and argue about issues related to the science topic with the presenter and each other. It is an important part of the popularity that the Cafes do not involve school or parents, but also that we have strived to give the kids ownership of the program. Each town has a Youth Leadership Team-open to any teen-that discusses and prioritizes potential topics, conducts

    The Eqo is a body scanner which allows images of the whole body to be obtained for safety purposes, without any exposure to ionising radiations, in a reliable and non-intrusive way in comparison with pat-down searching. Its technology is based on the use of so-called 'millimetre' waves. This expertise report is an answer to a public body request for an assessment of health risks related to the use of such a device. The authors first present the context of this investigation, and the Eqo gantry (operation, physical parameters, obtained image, control capacity, gantry usage). They report the assessment of electromagnetic field levels emitted by the Eqo gantry (measurement conditions, measurements), and the assessment of exposure to millimetre waves in relationship with the use of the Eqo gantry as far as passengers, airport workers and flight crews, operators, and testers are concerned. After a presentation of the potential health and biological effects of waves with a frequency higher than 1 GHz, the authors also report an assessment of health risks related to the use of Eqo (depth of penetration of waves into the body, issue of potential thermal and non thermal effects). Some recommendations are made

    2004-03-01

    De nos jours, il arrive quotidiennement aux grands hommes d'avoir à fréquenter d'ignorants mortels épris d'une conviction maladive que la science est la grande responsable de tous les maux du monde. Évidemment sans physique atomique, il n'y aurait pas eu d'Hiroshima et sans révolution industrielle, pas de pollution et etc. Cependant, ces accusations envers le progrès technique sont tout à fait injustes, irréfléchies et, j'irai même jusqu'à dire, irresponsables, puisque le calcul, i.e. la planification, même la plus élémentaire, est ce qui caractérise le mieux, pragmatiquement, la société humaine. À mon avis, les problèmes sociaux tireraient plutôt leur origine de sciences sociales irréalistes, qui, concrètment, inspireraient ou serviraient d'alibis à ceux qui détiennent véritablement le pouvoir. Dans cet article, je tenterai donc de démontrer la meilleure véracité et efficacité du matérialisme scientifique. Cette doctrine, dont Mario Bunge est le plus illustre représentant, s'appuy sur les résultats théoriques et expérimentaux des sciences factuelles ainsi que sur l'exactitude logique des mathématiques, utilisées ici comme langage universel de l'expression des idées. Cette conception philosophique qui s'inspire principalement du modèle des théories physiques, stipule que les réalités sociales sont, comme tout autre réalité, matérielles, mathématisables et représentables comme des systèmes en interaction. En fait, le modèle des physiciens ayant historiquement fait ses preuves en matière de testabilité et de cohérence interne est proposé d'être appliquer aux sciences sociales, aujourd'hui scindées des sciences dites pures sous l'inspiration des pseudo penseurs néo-kantiens, phénoménologiques et post-moderne. Cette nouvelle approche permettrait ainsi d'évoluer plus exactement vers une compréhension des bases sociales et biologiques du comportement humain afin de développer une éthique sans cesse plus r

    Eqo is a detection scanner portal used in airports for the detection of various materials on passengers. After a presentation of the context, scope and modalities of this expertise, this report presents the Eqo portal (main actors, operation, physical parameters, obtained image, control capacity, uses) and reports the assessment of the levels of electromagnetic fields emitted by this portal (measurement conditions and measurement devices, results in terms of frequency spectrum, time variations and power density) and the assessment of the exposure to millimetre-wavelength waves in relationship with the use of the Eqo portal (passengers, workers in the airports and airline personnel, operators). Then, it addresses the case of waves with a frequency higher than 1 GHz (potential biological and health effects, depth of penetration, biological studies, and epidemiological studies). The last part proposes an assessment of health risks related to the use of the Eqo portal

  15. Developing expertise in surgery.

    Alderson, David

    2010-01-01

    The concept of expertise is widely embraced but poorly defined in surgery. Dictionary definitions differentiate between authority and experience, while a third view sees expertise as a mind-set rather than a status. Both absolute and relative models of expertise have been developed, and each allows a richer understanding of the application of these concepts to emerge. Trainees must develop both independent and interdependent expertise, and an appreciation of the essentially constructivist and uncertain nature of medical knowledge. Approach may be more important than innate talent; the concepts of 'flow', sustained 'deliberate practice' and 'adaptive expertise' are examples of expert approaches to learning. Non-analytical reasoning plays a key role in decision making at expert levels of practice. A technically gifted surgeon may be seen as a safety hazard rather than an expert if inter-dependent expertise has not been developed. Key roles of a surgical educator are to facilitate the development of an expert approach to education and to enable entry into and movement towards the centre of an expert community of practice.

    The ProVision 100 is a body scanner which allows images of the whole body to be obtained for safety purposes, without any exposure to ionising radiations, in a reliable and non-intrusive way in comparison with pat-down searching. Its technology is based on the use of so-called 'millimetre' waves, between 24 and 30 GHz. This expertise report is an answer to a public body request for an assessment of health risks related to the use of such a device. The authors first present the context of this investigation, and then present various aspects of waves with a frequency greater than 1 GHz (physical properties, exposure sources, biological effects, health effects, regulation related to public exposure to electromagnetic waves). The ProVision 100 is then presented: operation parameters, emitted power, control capacity, gantry operation, obtained image, gantry usages, other technologies for body scanners). They report the assessment of the exposure of persons scanned by the Provision 100 gantry (assessment of electromagnetic field levels, assessment of exposure to millimetre waves), and the assessment of health risks related to the use of ProVision 100 (depth of penetration of waves into the body, issue of potential thermal and non thermal effects, and of interaction with medical devices). Issues related to privacy and human rights in relationship with the use of body scanners are then briefly discussed

    2012-06-01

    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.

  20. Beyond Faces and Expertise

    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

  6. Prescribing safety, negotiating expertise

    Rolina, Gregory

    2010-01-01

    Owing to their presumed impact on the safety of high-risk installations, the interactions between regulators and the regulated are a major but seldom explored subject of research in risk management. A study by experts on human and organizational factors in nuclear safety sheds light on the various phases (and their effects) of the process whereby experts produce assessments. Light is shed on a 'negotiated expertise' typical of the French style of safety regulations in nuclear installations. It is based on an ongoing technical dialog between experts and operators ('French cooking' for Anglo-Saxons). This analysis of 'expertise' and thus of the 'logics of action' implemented by experts proposes a typology of actions that can be transposed to other sorts of risk or other fields of activity. It hands us the keys for understanding a very contemporary activity. (author)

    In the middle of the 1970s when Sweden had realized half of its planned nuclear power programme (six reactors of twelve), nuclear power came up on the top of the political agenda. This paper reports that the new government, who had to make the final decisions about the programme, was divided and disagreed about the future use of nuclear power. When the crucial decisions had to be made the government consulted both the expertise and the general public (in a referendum), but the outcome of these consultations were used only to legitimate the government's decisions

  11. Expertise, Ethics Expertise, and Clinical Ethics Consultation: Achieving Terminological Clarity

    Science.gov (United States)

    Iltis, Ana S.; Sheehan, Mark

    2016-01-01

    The language of ethics expertise has become particularly important in bioethics in light of efforts to establish the value of the clinical ethics consultation (CEC), to specify who is qualified to function as a clinical ethics consultant, and to characterize how one should evaluate whether or not a person is so qualified. Supporters and skeptics about the possibility of ethics expertise use the language of ethics expertise in ways that reflect competing views about what ethics expertise entails. We argue for clarity in understanding the nature of expertise and ethics expertise. To be an ethics expert, we argue, is to be an expert in knowing what ought to be done. Any attempt to articulate expertise with respect to knowing what ought to be done must include an account of ethics that specifies the nature of moral truth and the means by which we access this truth or a theoretical account of ethics such that expertise in another domain is linked to knowing or being better at judging what ought to be done and the standards by which this “knowing” or “being better at judging” is determined. We conclude with a discussion of the implications of our analysis for the literature on ethics expertise in CEC. We do think that there are clear domains in which a clinical ethics consultant might be expert but we are skeptical about the possibility that this includes ethics expertise. Clinical ethics consultants should not be referred to as ethics experts. PMID:27256848

    Faucher, Caroline

    2011-04-01

    Development of professional expertise is the gradual transition from novice to expert within a profession. Studies on expertise in the profession of optometry have never been published. However, many studies have been performed in other health professions (e.g., nursing, medicine, physical therapy, occupational therapy). This report is an overview of the development of professional expertise that will highlight some applications for optometry. A 5-level scale of professional expertise development, divided into 2 parts, is described. The first part is the progression of students during their professional studies (novice, intermediate, competent). The second part is the professional development occurring during the practice years (advanced, expert). Personal and collective efforts are required to foster the progression toward expertise. Great interest for the profession, motivation, and deliberate practice are individual attitudes that help this progression. The "optometric community of practice," by means of university (professional) training, continuing education, and collaboration between colleagues, also contributes to this process. Professional development is an integral part of the Optometric Oath. Each clinical case is a potential learning experience contributing to one's professional development. Optometrists' attitudes are predominant factors in the progression from one level to another. Copyright © 2011 American Optometric Association. Published by Elsevier Inc. All rights reserved.

Certains éléments explicatifs sont proposés tels que la moindre demande pour ce type de savoir dans le public, et du côté interne aux universités, des formations disciplinaires et méthodes d’évaluation qui n’incitent pas à ces prises de parole.L’article est construit à travers l’analyse de cinq catégories de prise de position, ou de “fonction” d’intellectuel. Trois d’entre elles concernent de larges publics et des discours influents : se prononcer sur un sujet de sa spécialité, se prononcer sur les implications de sa discipline, prendre position sur tout type de sujet. Une quatrième catégorie concerne des collaborations plus ponctuelles de type “science citoyenne”. La cinquième enfin porte sur la gestion académique et professionnelle des domaines de savoirs.The topic of this paper is rooted in some kind of astonishment at the relatively weak part of scientists among recognized intellectuals despite the major importance of sciences in societies.

  19. Smart grids - French Expertise

    International Nuclear Information System (INIS)

    2015-11-01

    The adaptation of electrical systems is the focus of major work worldwide. Bringing electricity to new territories, modernizing existing electricity grids, implementing energy efficiency policies and deploying renewable energies, developing new uses for electricity, introducing electric vehicles - these are the challenges facing a multitude of regions and countries. Smart Grids are the result of the convergence of electrical systems technologies with information and communications technologies. They play a key role in addressing the above challenges. Smart Grid development is a major priority for both public and private-sector actors in France. The experience of French companies has grown with the current French electricity system, a system that already shows extensive levels of 'intelligence', efficiency and competitiveness. French expertise also leverages substantial competence in terms of 'systems engineering', and can provide a tailored response to meet all sorts of needs. French products and services span all the technical and commercial building blocks that make up the Smart Grid value chain. They address the following issues: Improving the use and valuation of renewable energies and decentralized means of production, by optimizing the balance between generation and consumption. Strengthening the intelligence of the transmission and distribution grids: developing 'Supergrid', digitizing substations in transmission networks, and automating the distribution grids are the focus of a great many projects designed to reinforce the 'self-healing' capacity of the grid. Improving the valuation of decentralized flexibilities: this involves, among others, deploying smart meters, reinforcing active energy efficiency measures, and boosting consumers' contribution to grid balancing, via practices such as demand response which implies the aggregation of flexibility among residential, business, and/or industrial sites.

    2007-01-01

    This paper describes under which conditions it is possible for the CERN Library to move, from 2008 on, to e-only for its periodical collection. This change is in accordance with the evolution of the users' practices, but shall also preserve the functions of scientific communication, i.e. registration, certification, awareness, archiving and rewarding. In this context, Open Access Publishing is considered as a solution to the difficulties brought by the electronic media regarding awareness and archiving, functions that Libraries are no longer in position to provide. After a description of some realizations based on the principles of Open Access (PlOS, NIH and Wellcome Trust), the presentation of SCOAP3 - the scheme adopted by CERN - illustrates how it is tailored to a specific community of users. This major about-turn requires the Library to position itself as a larger provider of information going beyond core High Energy Physics journals. Finally, it is also possible to imagine exiting the system by going wit...

    Full Text Available Si l'image documentaire, et à fortiori l'image scientifique est encore souvent perçue comme la réalité elle-même, elle n'est cependant qu’interprétation. Nous nous proposons ici, par une approche issue de l'histoire des techniques, d'interroger la construction des images liées à la pratique de biologiste. La mise en formes de ces images est tout à la fois le reflet de l'expérimentateur, de l'instrument, et celui de la connaissance de l'époque. Mais dans un désir de partage de la science au plus grand nombre, elles soulèvent aussi la question du lien existant entre science et fiction. Jean Painlevé (1902-1989, réalisateur et scientifique usant du cinématographe, met l'accent sur ce point dès les années trente. Conscient de notre tendance naturelle à l'anthropomorphisme, il souligne la nécessité d'une éducation du regard pour plus d'indépendance et d'esprit critique vis à vis des images. Et, en tirant du contenu scientifique lui même la substance et la dramaturgie de ses histoires, il propose une mise en fiction de la science qui renouvelle le genre documentaire.

  14. Wine Expertise Predicts Taste Phenotype.

    Hayes, John E; Pickering, Gary J

    2012-03-01

    Taste phenotypes have long been studied in relation to alcohol intake, dependence, and family history, with contradictory findings. However, on balance - with appropriate caveats about populations tested, outcomes measured and psychophysical methods used - an association between variation in taste responsiveness and some alcohol behaviors is supported. Recent work suggests super-tasting (operationalized via propylthiouracil (PROP) bitterness) not only associates with heightened response but also with more acute discrimination between stimuli. Here, we explore relationships between food and beverage adventurousness and taste phenotype. A convenience sample of wine drinkers (n=330) were recruited in Ontario and phenotyped for PROP bitterness via filter paper disk. They also filled out a short questionnaire regarding willingness to try new foods, alcoholic beverages and wines as well as level of wine involvement, which was used to classify them as a wine expert (n=110) or wine consumer (n=220). In univariate logisitic models, food adventurousness predicted trying new wines and beverages but not expertise. Likewise, wine expertise predicted willingness to try new wines and beverages but not foods. In separate multivariate logistic models, willingness to try new wines and beverages was predicted by expertise and food adventurousness but not PROP. However, mean PROP bitterness was higher among wine experts than wine consumers, and the conditional distribution functions differed between experts and consumers. In contrast, PROP means and distributions did not differ with food adventurousness. These data suggest individuals may self-select for specific professions based on sensory ability (i.e., an active gene-environment correlation) but phenotype does not explain willingness to try new stimuli.

    Nous présentons une méthode automatique d'importation de données mise en oeuvre au Service de l'Information Scientifique, SIS, du CERN. Ce programme informatique, baptisé Uploader, permet d'importer dans le catalogue de la bibliothèque du CERN des notices bibliographiques et le texte intégral de documents provenant de diverses sources sur Internet. Ces bases de données concernent la littérature grise en physique et dans les disciplines voisines (par exemple DOE, KEK, Math-Doc, TipTop, etc.). Cette politique d'acquisition, qui met en avant le traitement informatisé des ressources électroniques, soulève quelques réflexions sur l'augmentation du nombre de documents collectés et sur l'élargissement des domaines traités. Le souci constant d'enrichir ces données et d'en faciliter l'accès aux utilisateurs, sur un mode hypertextuel, conduit à une évolution des métiers de la gestion documentaire.

  18. Perceptual learning and human expertise.

    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

    Full Text Available Significant insights into visual cognition have come from studying real-world perceptual expertise. Many have previously reviewed empirical findings and theoretical developments from this work. Here we instead provide a brief perspective on approaches, considerations, and challenges to studying real-world perceptual expertise. We discuss factors like choosing to use real-world versus artificial object domains of expertise, selecting a target domain of real-world perceptual expertise, recruiting experts, evaluating their level of expertise, and experimentally testing experts in the lab and online. Throughout our perspective, we highlight expert birding (also called birdwatching as an example, as it has been used as a target domain for over two decades in the perceptual expertise literature.

    Increasing evidence suggests that musical expertise influences brain organization and brain functions. Moreover, results at the behavioral and neurophysiological levels reveal that musical expertise positively influences several aspects of speech processing, from auditory perception to speech production. In this review, we focus on the main results of the literature that led to the idea that musical expertise may benefit second language acquisition. We discuss several interpretations that may account for the influence of musical expertise on speech processing in native and foreign languages, and we propose new directions for future research.

    Mars-avril 1986: la comète de Halley est de retour, passant au plus près de la Terre.Rarement un événement à l'origine strictement astronomique aura à ce point été un événement scientifique. Pas moins de cinq sondes spatiales, en effet, ont été lancées pour rencontrer la comète et effectuer en mars 1986 la première exploration de son atmosphère. Rien, pourtant, ne semblait à l'origine militer pour un tel déploiement de moyens scientifiques: la comète ne dépasse pas en éclat les comètes non périodiques les plus brillantes; sa période de révolution _ 76 ans _ est longue; sa trajectoire est telle que le temps d'observation, lors du survol par les sondes, ne dure que quelques heures.Mais la comète de Halley _ du nom de l'astronome anglais Edmund Halley qui, appliquant les lois de la gravitation de Newton, en détermina les éléments orbitaux et prévit la réapparition de 1758 _ est la seule comète brillante et jeune dont la trajectoire soit parfaitement connue à l'avance.

    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.)

  10. 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.

    2002-01-01

    Full text: For many decades to come the international nuclear sector will require a wide range of highly trained, experienced and competent personnel. However, with the decline in the availability of nuclear expertise which is being felt in many countries, maintaining safety competence for both the industry and the regulator becomes a difficult challenge. Assessing the extent of the decline now and predicting what is the likely need for expertise in the future is an important task for all countries. Assessment should take account of likely scenarios for change in the nuclear industry and should aim to identify areas of expertise most likely to be at risk. International Agencies are playing a key role in raising awareness about regulatory concern and are starting to coordinate response and exchange good practice. Regulatory responsibility for preserving skills and expertise and International Agency leadership are essential for a successful outcome to the issue. (author)

    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 ?

  20. 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.

    Science.gov (United States)

    Cowley, Christopher

    2005-01-01

    There seem to be two clearly-defined camps in the debate over the problem of moral expertise. On the one hand are the "Professionals", who reject the possibility entirely, usually because of the intractable diversity of ethical beliefs. On the other hand are the "Ethicists", who criticise the Professionals for merely stipulating science as the most appropriate paradigm for discussions of expertise. While the subject matter and methodology of good ethical thinking is certainly different from that of good clinical thinking, they argue, this is no reason for rejecting the possibility of a distinctive kind of expertise in ethics, usually based on the idea of good justification. I want to argue that both are incorrect, partly because of the reasons given by one group against the other, but more importantly because both neglect what is most distinctive about ethics: that it is personal in a very specific way, without collapsing into relativism.

  3. Teachers’ Shared Expertise at a Multidisciplinary University of Applied Sciences

    Directory of Open Access Journals (Sweden)

    Arto O. Salonen

    2015-07-01

    Full Text Available Shared expertise, team teaching, and cooperation among lecturers from different fields have become more and more important in promoting learning and achieving more innovative learning outcomes in multidisciplinary universities. To increase and improve sharing expertise between teachers from different faculties and disciplines, we wanted, on one hand, to identify skills and competences that teachers have in common and, on the other hand, to find areas in which they identify that they need complementation. As a framework for this research, we applied Lee Shulman’s (1986 seven categories of teachers’ knowledge base including the theory of pedagogical content knowledge (PCK. The data were collected by group discussions. The teachers (N = 22 represented all seven faculties of Helsinki Metropolia University of Applied Sciences (UAS, that is, Business School, Civil Engineering and Building Services, Culture and Creative Industries, Health Care and Nursing, School of Information and Communication Technology (ICT, Industrial Engineering, and Welfare and Human Functioning. The data were analyzed using theory-based content analysis. According to our data, the mutual core competence of a teacher is the capacity to interact effectively. It is a basis for shared expertise. Interaction skills are necessary in collaborative construction of knowledge as students, teachers of different fields, and their partners inside and outside the organization co-operate. Multidisciplinary co-operation among colleagues also helps to maintain subject matter knowledge, as it supports peer learning and encourages everyone to move out of their comfort zones.

  4. Exploring Integration in Action: Competencies as Building Blocks of Expertise.

    2017-12-01

    Competency frameworks such as the CanMEDS roles and the ACGME core competencies may lead to the implicit assumption that physicians can learn and practice individual competencies in isolation. In contrast, models of adaptive expertise suggest that the integration of competencies reflects the capabilities of an expert physician. Thus, educational programming aimed at teaching discrete roles or competencies might overlook expert physician capabilities that are central to patient care. To develop expertise, learning opportunities must reflect expert capabilities. To better understand the relationship between competency-based medical education and expert development, the authors sought to explore how integrated competencies are enacted during patient care by postgraduate medical trainees. Using a cognitive ethnographic approach, in 2014-2015 the authors conducted observations and-to refine and elaborate these observations-ad hoc informal interviews with 13 postgraduate trainee participants. Data collection resulted in 92 hours of observation, 26 patient case portraits, and a total of 220 pages of field notes for analysis. Through analysis, the authors identified and examined moments when postgraduate trainees appeared to be simultaneously enacting multiple competencies. The authors identified two key expert capabilities in moments of integrated competence: finding complexity and being patient-centered. They described two mechanisms for these forms of integration: valuing the patient's narrative of their illness, and integrated understanding. Understanding integrated competencies as the building blocks of expert capabilities, along with recognizing the importance of mechanisms that support integration, offers an opportunity to use existing competency-based frameworks to understand and teach adaptive expertise.

    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. Les formes de "contrôle social" patriquées en France servent de contrepoint à la construction de ce qui est ici exposé.

    Le siècle qui s'achève aura été marqué par des révolutions scientifiques sans précédent dans la forme comme dans les contenus du savoir. Elles ont retenti sur l'image de la nature comme sur celle de l'homme, brisant les portraits désormais obsolètes qu'en avaient brossés la science et la philosophie classiques. Après Einstein, de Broglie ou Schrödinger, comme après Heisenberg, Dirac ou Feynman, on ne pense plus tout à fait comme avant. Et il en va de même après Poincaré, Hadamard ou Kolmogorov. Trois grandes révolutions physiques seront ici étudiées en détail : la théorie de la relativité (restreinte et générale) ; la mécanique quantique (et ses différentes interprétations) ; la théorie du chaos déterministe (sa préhistoire comme ses applications). Toutes trois contribuent en effet à modifier les réponses que l'on peut apporter aux grandes questions métaphysiques et à esquisser un paysage philosophique nouveau. Dans la tradition de l'épistémologie française, ce livre ent...

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.

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.

  4. Using Highlighting to Train Attentional Expertise.

    Directory of Open Access Journals (Sweden)

    Brett Roads

    Full Text Available 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.

    2002-01-01

    As a result of the growing difficulties confronting the heads of public and private high-risk activities, expertise practices have changed radically over the past years in the areas of risk assessment and management. In answer to the erosion of the credibility and legitimacy of traditional 'scientific' expertise, new forms of expertise based on citizen participation have emerged, particularly in fields involving public trust. The author's aim is to analyse the main changes in the field of radiological protection, on the basis of his 25 years of experience in the field. In conclusion, the author discusses the independence of expert assessment, an issue central to the present debate on the organization and practice of expertise in the field of high-risk activities

    Full Text Available Abstract The Bamako Call for Action on Research for Health stresses the importance of inter-disciplinary, inter-ministerial and inter-sectoral working. This challenges much of our current research and postgraduate research training in health, which mostly seeks to produce narrowly focused content specialists. We now need to compliment this type of research and research training, by offering alternative pathways that seek to create expertise, not only in specific narrow content areas, but also in the process and context of research, as well as in the interaction of these different facets of knowledge. Such an approach, developing 'integrative expertise', could greatly facilitate better research utilisation, helping policy makers and practitioners work through more evidence-based practice and across traditional research boundaries.

    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.

    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.

    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.

    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.

    International Nuclear Information System (INIS)

    Rolina, Gregory

    2008-01-01

    This Ph.D thesis is dedicated to a specific type of expertise, the safety of nuclear installations in the field of human and organisational factors. Empirical work is at the foundation of this thesis: the monitoring of experts 'in action', allowed a detailed reconstruction of three cases they were examining. The analysis, at the core of which lies the definition of what an efficient expertise can be, emphasizes the incompleteness of the knowledge that links together the nuclear facilities' organisational characteristics and their safety. This leads us to identify the expert's three ranges of actions (rhetorical, cognitive, operative). Defined from objectives and constraints likely to influence the expert's behaviour, those three ranges each require specific skills. A conception of expertise based on these ranges seems adaptable to other sectors and allows an enrichment of models of expertise cited in literature. Historical elements from French institutions of nuclear safety are also called upon to take into consideration some of the determinants of the expertise; its efficiency relies on the upholding of a continuous dialogue between the regulators (the experts and the control authority) and the regulated (the operators). This type of historically inherited regulation makes up a specificity of the French system of external control of nuclear risks. (author) [fr

  19. A phenomenological investigation of science center exhibition developers' expertise development

    Young, Denise L.

    The purpose of this study was to examine the exhibition developer role in the context of United States (U.S.) science centers, and more specifically, to investigate the way science center exhibition developers build their professional expertise. This research investigated how successfully practicing exhibition developers described their current practices, how they learned to be exhibition developers, and what factors were the most important to the developers in building their professional expertise. Qualitative data was gathered from 10 currently practicing exhibition developers from three science centers: the Exploratorium, San Francisco, California; the Field Museum, Chicago, Illinois; and the Science Museum of Minnesota, St. Paul, Minnesota. In-depth, semistructured interviews were used to collect the data. The study embraced aspects of the phenomenological tradition and sought to derive a holistic understanding of the position and how expertise was built for it. The data were methodically coded and organized into themes prior to analysis. The data analysis found that the position consisted of numerous and varied activities, but the developers' primary roles were advocating for the visitor, storytelling, and mediating information and ideas. They conducted these activities in the context of a team and relied on an established exhibition planning process to guide their work. Developers described a process of learning exhibition development that was experiential in nature. Learning through daily practice was key, though they also consulted with mentors and relied on visitor studies to gauge the effectiveness of their work. They were adept at integrating prior knowledge gained from many aspects of their lives into their practice. The developers described several internal factors that contributed to their expertise development including the desire to help others, a natural curiosity about the world, a commitment to learning, and the ability to accept critique.

    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.

By looking at the policy recommendations of the Bank of International Settlements, the International Monetary Fund and the Financial Stability Board, we show how experts tied to these institutions secured control over how shadow...... banking is treated. In so doing, these technocrats reinforced each other’s expertise and excluded some potential competitors (legal scholars), coopted others (select Fed and elite academic economists). The findings have important implications for studying the relationship between IOs technocrats...

    In this study, we investigated whether team-level knowledge sharing moderates the effects of individual-level expertise dissimilarity on individual employees' creativity in research and development (R&D) project teams. Expertise dissimilarity--defined as the difference in expertise and knowledge between a focal team member and her or his fellow team members--was operationalized in terms of the research department to which each member belonged. In Study 1, multilevel analyses of data collected from 200 members of 40 R&D project teams in a telecommunications company revealed that a team member with expertise dissimilar to that of her or his teammates was more likely to exhibit creativity when the project team as a whole engaged in higher levels of tacit, rather than explicit, knowledge sharing. In contrast, a member whose expertise was similar to that of her or his teammates was more likely to exhibit creative behavior when the team engaged in higher levels of explicit, rather than tacit, knowledge sharing. These findings were largely replicated in Study 2 using data collected from 82 members of 25 project teams from another telecommunications company.

    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.

    1997-01-01

    Relying on the outstanding performances of the reprocessing facilities and the growing fabrication facilities, the in-reactor Pu recycling program in France and in other European countries is steadily implemented and has reached full-scale industrial operation. The RCR strategy -Reprocessing, Conditioning and Recycling- developed by COGEMA is now a well proven industrial reality. In 1997, plutonium recycling through MOX fuel is a mature industry, with successful operational experience and large-scale fabrication plants. In this field, COGEMA is the main actor, on operating simultaneously three complete multidesign fuel production plants: MELOX plant (in Marcoule), CADARACHE plant and DESSEL plant (in Belgium). Present MOX production capacity available to COGEMA fits 175 tHM per year and will be extended to reach about 325 tHM in the year 2000, that will represent 75% of the total MOX fabrication capacity in Europe. The industrial mastery and the high production level in MOX production assured by high technology processes confers COGEMA an unrivalled expertise for Pu recycling. This allows COGEMA to be a major actor in Pu-based fuels in the coming second nuclear era with advanced fuel cycles. The paper depicts the steps of the progressive advance of COGEMA to reach the Pu recycling expertise. (author)

    The aim of this experiment was to investigate the influence of musical expertise on the automatic perception of foreign syllables and harmonic sounds. 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 are discussed.

  11. Beyond Faces and Expertise: Facelike Holistic Processing of Nonface Objects in the Absence of Expertise.

    Science.gov (United States)

    Zhao, Mintao; Bülthoff, Heinrich H; Bülthoff, Isabelle

    2016-02-01

    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. © The Author(s) 2015.

    Full text: The nuclear industry worldwide faces the challenge of preserving the existing expertise, competence and knowledge despite of the ageing workforce and upcoming retirements. Challenges are also imposed by the reducing amount of new recruits and students entering the nuclear industry, which amounts to fewer young professionals that have the potential to become nuclear experts in the future. Although many other industries share similar challenges, the preservation of expertise in the nuclear industry is even more important due to the safety-critical nature of the nuclear operations and the special characteristics that high-reliability organizations such as nuclear power plants have. As a response to the risk of knowledge loss, nuclear organizations have engaged in knowledge capturing efforts. New information systems and organizational practices have been implemented to safeguard nuclear expertise. Recently, IAEA has proposed nuclear organizations to design and adopt people-centered programs that encompass themes such as workforce planning, recruitment, training, succession planning, leadership development and knowledge management. Thus, in order to address the current risks to nuclear expertise, attention should be focused on these different areas and corresponding human resources (HR) functions within the nuclear organizations. Our paper presents results from a project which examines the nature of expert work and human resources (HR) functions that support the development and preservation of expertise. The study adopts a qualitative cross-sectional case study design. Two organizational units from different nuclear industry organizations have been selected as cases. The research data will be gathered in April-May 2007 and preliminary results will be presented in the International Conference of Knowledge Management in Nuclear Facilities, in June 2007. The main data will comprise of thematic interviews to experts, their managers and HR representatives

  13. Expertise in Everyday Nurse–Patient Conversations

    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: Since the mid of eighties several important changes in human beings behaviour, which influence nuclear field, can be observed - the loss of interest in studying technical disciplines (namely nuclear), strong pressure of environmental movements, stagnation of electricity consumption and deregulation of electric markets. All these factors create conditions which are leading to the decrease of job positions related to the nuclear field connected particularly with research, design and engineering. Loss of interest in studying nuclear disciplines together with the decrease of number of job positions has led to the declining of university enrolments, closing of university departments and research reactors. In this manner just a very small number of appropriately educated new experts are brought In the same moment the additional internal factor - the relative ageing of the human workforce on both sites operators of nuclear facilities and research and engineering organisations can be observed. All these factors, if not addressed properly, could lead to the loss of nuclear expertise and the loss of nuclear expertise represents the direct thread to the nuclear safety. The latest studies have shown that at present NPPs cannot be replaced by other kinds of electric sources and in no case by renewable ones in an efficient manner. Therefore it is necessary to carefully manage knowledge gathered in the nuclear field during the years and to keep on the nuclear safety research, education and training to ensure and upgrade safe and reliable operation of existing and future nuclear facilities. This is responsibility of both the governments of the states using nuclear applications and owners of nuclear facilities. (author)

    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

    In a sample of 263 male GO players at 48 levels of expertise and ranging from 18 to 78 years of age, it was found that factors of expertise deductive reasoning (EDR) and expertise working memory (EWM) were independent of factors of fluid reasoning (Gf) and short-term working memory (STWM) that, along with cognitive speed (Gs), have been found to characterize decline of intelligence in adulthood. The main effects of analyses of cross-sectional age differences indicated age-related decline in EDR and EWM as well as in Gf, STWM, and Gs. However, interaction and partialing analyses indicated that decline in EDR and EWM decreased to no decline with increase in level of expertise. The results thus suggest that with increase in factors known to raise the level of expertise--particularly, intensive, well-designed practice--there may be no age-related decline in the intelligence that is measured in the abilities of expertise.

  18. Unitizing worker expertise and maximizing the brain reward centers

    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

    Walker, Shawn; Parker, Pam; Scamell, Mandie

    2018-06-01

    The safety of vaginal breech birth depends on the expertise of birth attendants, yet the meaning of "expertise" remains unclear and subjectively defined. The objective of this study was to define expertise and the roles experts may play in expanding access to this service. We performed an integrative analysis of two strands of data concerning expertise in physiological breech birth, including the following: survey data from a Delphi study involving 26 very experienced clinicians (mean experience = 135 breech births) and 2 service user representatives, and interviews from a grounded theory study of 14 clinicians more moderately experienced with physiological methods (5-30 upright breech births). Data were pooled and analyzed using constant comparative methods. Expertise is defined by its ongoing function, the generation of comparatively good outcomes, and confidence and competence among colleagues. Although clinical experience is important, expertise is developed and expressed in social clinical roles, which expand as experience grows: clinician, mentor, specialist, and expert. To develop expertise within a service, clinicians who have an interest in breech birth should be supported to perform these roles within specialist teams. Specialist breech teams may facilitate the development of expertise within maternity care settings. Evaluation of expertise based on enablement of women and colleagues, as well as outcomes, will potentially avoid the pitfalls of alienation produced by some forms of specialist authority. © 2017 Wiley Periodicals, Inc.

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

    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.

    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.

    Forensic facial identification examiners are required to match the identity of faces in images that vary substantially, owing to changes in viewing conditions and in a person's appearance. These identifications affect the course and outcome of criminal investigations and convictions. Despite calls for research on sources of human error in forensic examination, existing scientific knowledge of face matching accuracy is based, almost exclusively, on people without formal training. Here, we administered three challenging face matching tests to a group of forensic examiners with many years' experience of comparing face images for law enforcement and government agencies. Examiners outperformed untrained participants and computer algorithms, thereby providing the first evidence that these examiners are experts at this task. Notably, computationally fusing responses of multiple experts produced near-perfect performance. Results also revealed qualitative differences between expert and non-expert performance. First, examiners' superiority was greatest at longer exposure durations, suggestive of more entailed comparison in forensic examiners. Second, experts were less impaired by image inversion than non-expert students, contrasting with face memory studies that show larger face inversion effects in high performers. We conclude that expertise in matching identity across unfamiliar face images is supported by processes that differ qualitatively from those supporting memory for individual faces. © 2015 The Author(s).

    The debate over the origins of individual differences in expertise has raged for over a century in psychology. The "nature" view holds that expertise reflects "innate talent"-that is, genetically determined abilities. The "nurture" view counters that, if talent even exists, its effects on ultimate performance are negligible. While no scientist takes seriously a strict nature-only view of expertise, the nurture view has gained tremendous popularity over the past several decades. This environmentalist view holds that individual differences in expertise reflect training history, with no important contribution to ultimate performance by innate ability ("talent"). Here, we argue that, despite its popularity, this view is inadequate to account for the evidence concerning the origins of expertise that has accumulated since the view was first proposed. More generally, we argue that the nature versus nurture debate in research on expertise is over-or certainly should be, as it has been in other areas of psychological research for decades. We describe a multifactorial model for research on the nature and nurture of expertise, which we believe will provide a progressive direction for future research on expertise. © 2018 New York Academy of Sciences.

  10. Maintaining nuclear competence and expertise in Japan

    International Nuclear Information System (INIS)

    Fujii, Y.

    2004-01-01

    The fundamental law of atomic energy, which strictly restricts the application of atomic energy to the peaceful use, was established in 1955 in Japan. Since then, during the past five decades, great efforts were made to develop atomic energy. So far 52 units of light water reactors, 29 BWRs and 23 PWRs, have been built and in operation, 5 units are under construction and 6 units are planed to be built. Total capacity of presently operated NPPs amounts to 45.7 Gwe and the nuclear energy shares 30 % of the total electricity generation in Japan. During the past 10 years, several accidents occur in the nuclear facilities of electric power companies, and JNC ( previously PNC ). In spite of these accidents, including the accident of Kansai Electric Power Co. this year, the important role of nuclear energy to sustain the lives of people in Japan is intact. In the nuclear energy projection, the construction of NPPs continues till 2010. Thereafter reconstructions of NPPs are foreseen in the decade 2030's for the replacement of present NPPs in operation after 60 years services. Attention has been directed to the technology preservation: how competence and expertise of nuclear engineering can be maintained till the next period of replacement construction, in particular, the period between years 2010 and 2030. The present paper reviews the status of nuclear engineering programs in universities in Japan. The nuclear education programs started in graduate schools in 1957 and expanded to undergraduate schools of major national universities. Presently nine universities are providing systematic nuclear education programs in their graduate schools, although the corresponding department have been changed their names from 'nuclear' to more broaden terms of 'quantum', 'energy' and 'system' in several universities. Under the conditions of shrinking nuclear industries, how to maintain the present education system is seriously concerned matter in the universities. The present paper

    2013-06-01

    Full Text Available This study reviews the literature on audit committee expertise and financial reporting timeliness. Financial reporting timeliness and audit committee expertise are two areas of research gaining the attention of a large number of stakeholders because they contribute to the reliability and the  relevancy of financial reporting. Indeed, the focus of this review is primarily on the recent developments in the pertinent literature in order to show the limitations of such research and encourage future research to overcome these limitations. By also looking at the development of the audit committee expertise literature, this study concludes that (1 like most audit committee literature, financial reporting timeliness literature continues to assume the absence of the contribution of expertise other than financial expertise, and ignore the role of audit committee chair; (2 most of this literature fails to find a significant effect because it ignores the interaction among corporate governance mechanisms. Accordingly, this study posits that ignoring the issues raised in such research by future research would lead to major mistakes in reforms relating to how the quality of financial reporting can be enhanced.

    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.

  14. How student models of expertise and innovation impact the development of adaptive expertise in medicine.

    The ability to innovate new solutions in response to daily workplace challenges is an important component of adaptive expertise. Exploring how to optimally develop this skill is therefore of paramount importance to education researchers. This is certainly no less true in health care, where optimal patient care is contingent on the continuous efforts of doctors and other health care workers to provide the best care to their patients through the development and incorporation of new knowledge. Medical education programmes must therefore foster the skills and attitudes necessary to engage future doctors in the systematic development of innovative problem solving. The aim of this paper is to describe the perceptions and experiences of medical students in their third and fourth years of training, and to explore their understanding of their development as adaptive experts. A sample of 25 medical students participated in individual 45-60-minute semi-structured interviews. Interviews were audiotaped, transcribed and entered into NVivo qualitative data analysis software to facilitate a thematic analysis. The analysis was both inductive, in that themes were generated from the data, and deductive, in that our data were meaningful when interpreted in the context of theories of adaptive expertise. Participants expressed a general belief that, as learners in the health care system, exerting any effort to be innovative was beyond the scope of their responsibilities. Generally, students suggested that innovative practice was the prerogative of experts and an outcome of expert development centred on the acquisition of knowledge and experience. Students' perceptions of themselves as having no responsibility to be innovative in their learning process have implications for their learning trajectories as adaptive experts.

    Qu'est-ce que l'analyse numérique ? C'est un ensemble d'outils qui permet d'obtenir une solution numérique approchée d'un problème mathématique, lui-même modèle d'une question technique ou scientifique. Pourquoi étudier (et enseigner) l'analyse numérique conçue de cette manière ? N'est-il pas suffisant d'appuyer sur la touche «solve» d'une calculette pour résoudre une équation algébrique ? Si l'on veut vraiment utiliser un logiciel, pourquoi faire plus que d'appeler, à l'intérieur d'un logiciel de haut niveau, la fonction «solve» ? En réalité, il est toujours profitable de connaître le principe de fonctionnement des outils que l'on utilise afin de les employer au mieux et pour être conscient de leurs limites. De plus, il peut arriver qu'un programme, bien qu'immédiatement disponible, ne soit pas parfaitement adapté à l'usage prévu ; seul l'utilisateur bien informé pourra le modifier en connaissance de cause et étendre son domaine de validité.

    Danovitch, Judith H; Shenouda, Christine K

    2018-01-01

    Adults and children use information about expertise to infer what a person is likely to know, but it is unclear whether they realize that expertise also has implications for learning. We explore adults' and children's understanding that expertise in a particular category supports learning about a closely related category. In four experiments, 5-year-olds and adults (n = 160) judged which of two people would be better at learning about a new category. When faced with an expert and a nonexpert, adults consistently indicated that expertise supports learning in a closely related category; however, children's judgments were inconsistent and were strongly influenced by the description of the nonexpert. The results suggest that although children understand what it means to be an expert, they may judge an individual's learning capacity based on different considerations than adults.

  20. Negotiating knowledges and expertise in refugee resettlement organizations

    Directory of Open Access Journals (Sweden)

    Sarah Steimel

    2016-12-01

    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.

    2018-03-08

    In this era of increasing complexity, there is a growing gap between what we need our medical experts to do and the training we provide them. While medical education has a long history of being guided by theories of expertise to inform curriculum design and implementation, the theories that currently underpin our educational programs do not account for the expertise necessary for excellence in the changing health care context. The more comprehensive view of expertise gained by research on both clinical reasoning and adaptive expertise provides a useful framing for re-shaping physician education, placing emphasis on the training of clinicians who will be adaptive experts. That is, have both the ability to apply their extensive knowledge base as well as create new knowledge as dictated by patient needs and context. Three key educational approaches have been shown to foster the development of adaptive expertise: learning that emphasizes understanding, providing students with opportunities to embrace struggle and discovery in their learning, and maximizing variation in the teaching of clinical concepts. There is solid evidence that a commitment to these educational approaches can help medical educators to set trainees on the path towards adaptive expertise. © 2018 John Wiley & Sons, Ltd.

    Reyes-Galindo, Luis I; Duarte, Tiago Ribeiro

    2015-02-01

    We analyse a recent paper by Goddiksen (2014) where the author raises questions about the relationship between authorship, attribution and Collins & Evans' concept of contributory and interactional expertise. We then highlight recent empirical work in the sociology of climate change science that has made similar points in order to clarify how authorship, division of labour and contribution are handled in real scientific settings. Despite this, Goddiksen's critique of both contributory and interactional expertise is ultimately ineffective because it rests on a misguided attempt to de-socialise these concepts. We conclude by stressing the importance of collective tacit knowledge acquisition through immersion as a critical step in becoming a full-blown contributory or interactional expert.

    Traumatic brain injuries have major socio-economic importance due to their frequency, high mortality and serious consequences. According to their nature the consequences of these injuries may be classified as neurological, psychiatric and esthetic. Various lesions of brain structures cause neurological consequences such as disturbance of motor functions, sensibility, coordination or involuntary movements, speech disturbances and other deviations, as well as epilepsy. Psychiatric consequences include cognitive deficit, emotional disturbances and behavior disturbances. CRIMINAL-LEGAL ASPECT OF TRAUMATIC BRAIN INJURIES AND LITIGATION: Criminal-legal aspect of traumatic brain injuries expertise understands the qualification of these injuries as mild, serious and qualified serious body injuries as well as the expertise about the mechanisms of their occurrence. Litigation expertise includes the estimation of pain, fear, diminished, i.e. lost vital activity and disability, esthetic marring, and psychological suffer based on the diminished general vital activity and esthetic marring. Evaluation of consequences of traumatic brain injuries should be performed only when it can be positively confirmed that they are permanent, i.e. at least one year after the injury. Expertise of these injuries is interdisciplinary. Among clinical doctors the most competent medical expert is the one who is in charge for diagnostics and injury treatment, with the recommendation to avoid, if possible, the doctor who conducted treatment. For the estimation of general vital activity, the neurological consequences, pain and esthetic marring expertise, the most competent doctors are neurosurgeon and neurologist. Psychological psychiatric consequences and fear expertise have to be performed by the psychiatrist. Specialists of forensic medicine contribute with knowledge of criminal low and legal expertise.

    Expert knowledge is a valuable source of information with a wide range of research applications. Despite the recent advances in defining expert knowledge, little attention has been given to how to view expertise as a system of interacting contributory factors for quantifying an individual's expertise. We present a systems approach to expertise that accounts for many contributing factors and their inter-relationships and allows quantification of an individual's expertise. A Bayesian network (BN) was chosen for this purpose. For illustration, we focused on taxonomic expertise. The model structure was developed in consultation with taxonomists. The relative importance of the factors within the network was determined by a second set of taxonomists (supra-experts) who also provided validation of the model structure. Model performance was assessed by applying the model to hypothetical career states of taxonomists designed to incorporate known differences in career states for model testing. The resulting BN model consisted of 18 primary nodes feeding through one to three higher-order nodes before converging on the target node (Taxonomic Expert). There was strong consistency among node weights provided by the supra-experts for some nodes, but not others. The higher-order nodes, “Quality of work” and “Total productivity”, had the greatest weights. Sensitivity analysis indicated that although some factors had stronger influence in the outer nodes of the network, there was relatively equal influence of the factors leading directly into the target node. Despite the differences in the node weights provided by our supra-experts, there was good agreement among assessments of our hypothetical experts that accurately reflected differences we had specified. This systems approach provides a way of assessing the overall level of expertise of individuals, accounting for multiple contributory factors, and their interactions. Our approach is adaptable to other situations where it

    While there is widespread interest in and admiration of individuals with exceptional talents, surprisingly little is known about the cognitive and neural mechanisms underpinning talent, and indeed how talent relates to expertise. Because many talents are first identified and nurtured in childhood, it can be difficult to determine whether talent is innate, can be acquired through extensive practice or can only be acquired in the presence of the developing brain. We sought to address some of these issues by studying healthy adults who acquired expertise in adulthood. We focused on the domain of memory and used licensed London taxi drivers as a model system. Taxi drivers have to learn the layout of 25,000 streets in London and the locations of thousands of places of interest, and pass stringent examinations in order to obtain an operating licence. Using neuropsychological assessment and structural and functional magnetic resonance imaging, we addressed a range of key questions: in the context of a fully developed brain and an average IQ, can people acquire expertise to an exceptional level; what are the neural signatures, both structural and functional, associated with the use of expertise; does expertise change the brain compared with unskilled control participants; does it confer any cognitive advantages, and similarly, does it come at a cost to other functions? By studying retired taxi drivers, we also consider what happens to their brains and behaviour when experts stop using their skill. Finally, we discuss how the expertise of taxi drivers might relate to the issue of talent and innate abilities. We suggest that exploring talent and expertise in this manner could have implications for education, rehabilitation of patients with cognitive impairments, understanding individual differences and possibly conditions such as autism where exceptional abilities can be a feature.

  9. Both novelty and expertise increase action observation network activity

    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.

    2007-01-01

    Full Text Available In this study, we attempt to understand better the influence of scientific teaching on the intellectual development of 5 to 6 year old children. The conception of child intellectual development used is based on a model suggested by Piaget and Garcia (1983, which explains the transformations of the understanding of the world by young children, and on Vygotskian conception which emphasizes the importance of the adult mediation and tutoring. Then, we developed a sequence of activities involving the understanding of shadow formation by young children, with the aim of transforming the way they understand physical phenomena. This sequence was carried out in kindergarten, with a group of pupils thought by their own teacher. The children's progresses were analysed, using their own statements and graphic productions, obtained during individual interviews achieved first before the teaching sequence, and then two months later. The collected data show that children progress in their reading of reality, as they come out of the purely perceptive framework ("intra-objectal", by building observables which imply an "inter-objectal" treatment of physical phenomena. These conclusions reinforce the idea that a scientific initiation in kindergarten, based on a good knowledge of the children's abilities, contributes to their intellectual development.

    The original Hubble Space Telescope archive showed how encapsulating expertise in science-ready data products could accelerate the pace of scientific advancement, and enable extremely productive archival research. In the 2000s, MAST and the Hubble Legacy Archive showed how taking these products to the next level further democratized astronomy, with archival science overtaking PI science as the dominant output of MAST missions. We argue that these data products fundamentally act as a vector for expertise, allowing novice users access to the detailed and advanced techniques of experts. In the 2020s we will see an explosion of data volume, data precision, and data complexity which will demand an even more powerful and sophisticated expertise engine. We’ll discuss how MAST plans to rise to meet that challenge.

    The present manuscript summarizes and discusses the implications of recent neuroimaging studies, which have investigated the relationship between musical expertise and structural, as well as functional, changes in an auditory-related association cortex, namely, the planum temporale (PT). Since the bilateral PT is known to serve as a spectrotemporal processor that supports perception of acoustic modulations in both speech and music, it comes as no surprise that musical expertise corresponds to functional sensitivity and neuroanatomical changes in cortical architecture. In this context, we focus on the following question: To what extent does musical expertise affect the functioning of the left and right plana temporalia? We discuss the relationship between behavioral, hemodynamic, and neuroanatomical data obtained from musicians in light of maturational and developmental issues. In particular, we introduce two studies of our group that show to what extent brains of musicians are more proficient in phonetic task performance. © 2012 New York Academy of Sciences.

    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.

  15. You can’t teach speed: sprinters falsify the deliberate practice model of expertise

    Directory of Open Access Journals (Sweden)

    Michael P. Lombardo

    2014-06-01

    Full Text Available 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 champions and the 20 fastest American men in U.S. history. In all documented cases, sprinters were exceptional prior to initiating training, and most reached world class status rapidly (Study 1 median = 3 years; Study 2 = 7.5. In Study 3 we surveyed U.S. national collegiate championships qualifiers in sprinters (n = 20 and throwers (n = 44. Sprinters recalled being faster as youths than did throwers, whereas throwers recalled greater strength and throwing ability. Sprinters’ best performances in their first season of high school, generally the onset of formal training, were consistently faster than 95–99% of their peers. Collectively, these results falsify the DPM for sprinting. Because speed is foundational for many sports, they challenge the DPM generally.

    Introduction Paediatricians with Expertise in Cardiology assess children with a full history, examination, and often perform an echocardiogram. A minority are then referred to an outreach clinic run jointly with a visiting paediatric cardiologist. The accuracy of the echocardiography diagnosis made by the Paediatrician with Expertise in Cardiology is unknown. Materials and methods We conducted a retrospective review of clinic letters for children seen in the outreach clinic for the first time between March, 2004 and March, 2011. Children with CHD diagnosed antenatally or elsewhere were excluded. We recorded the echocardiography diagnosis made by the paediatric cardiologist and previously by the Paediatrician with Expertise in Cardiology. The Paediatrician with Expertise in Cardiology referred 317/3145 (10%) children seen in the local cardiac clinics to the outreach clinic over this period, and among them 296 were eligible for inclusion. Their median age was 1.5 years (range 1 month-15.1 years). For 244 (82%) children, there was complete diagnostic agreement between the Paediatrician with Expertise in Cardiology and the paediatric cardiologist. For 29 (10%) children, the main diagnosis was identical with additional findings made by the paediatric cardiologist. The abnormality had resolved in 17 (6%) cases by the time of clinic attendance. In six (2%) patients, the paediatric cardiologist made a different diagnosis. In total, 138 (47%) patients underwent a surgical or catheter intervention. Discussion Paediatricians with Expertise in Cardiology can make accurate diagnoses of CHD in children referred to their clinics. This can allow effective triage of children attending the outreach clinic, making best use of limited specialist resources.

    Taba, Seyedamir Tavakoli; Hossain, Liaquat; Willis, Karen; Lewis, Sarah

    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.

  13. 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

  20. Organizational change and human expertise in nuclear power plants

    International Nuclear Information System (INIS)

    Masson, M.; Malaisc, N.

    1992-01-01

    Reliability and safety are two very important goals, which depend on technical and organizational factors, but also on human expertise. How to ensure a safe functioning of a nuclear power plant in a changing context, and what might be the role and aspects of training and transfer of knowledge? These are the questions we shall deal with in this paper, on the basis of two field studies. The two field studies stress the needs for setting up case based training, which best ensure the acquisition of know-how. Furthermore, as shown by the second one, gaining expertise involves developing large repertoires of highly skilled, semi-routinized activities. Supporting expert operators not only should tackle problem solving activities but should thus also include the prevention of routine errors, which go along with skill acquisition. (author)

  1. Development of the CAI system for inheritance of maintenance expertise

    Hanafusa, Hidemitsu; Chigusa, Naoki; Furuta, Kazuo

    2002-01-01

    High quality maintenance is required in order to secure the safety of nuclear power plants. The engineers engaged in maintenance activities have to master various knowledge, including the explicit and tacit knowledge of experienced experts, through education and training. Moreover, it is also very important to prevent these knowledge from getting scattered and lost with a change of generation and to share the knowledge or expertise. The purpose of this study is to develop a support system for the next generation experts to help them master and make use of the knowledge of their predecessors. The knowledge or expertise consist of ''knowledge about the maintenance tasks'', ''knowledge about structure/function of plant system/equipment'', and ''individual knowledge based on trouble experience etc.''. The ways this knowledge could be represented were considered first, then this support system was developed based on such representation. (author)

    Full Text Available Expertise development in the massively multiplayer online game World of Warcraft (Blizzard Entertainment, 2004 depends greatly on a player's use of social skills to gain access to expert player groups and accrue social and cultural capital. Drawn from ethnographic research, this paper maps out various forms of expert practice and highlights the social aspects of game play that often eclipse the importance of game-mechanics knowledge. At the time of this research, playing World of Warcraft and developing expertise in the game happened roughly within a two-stage process: (1 leveling up, or advancing one's character or avatar while learning the mechanics of the game, and (2 drawing on social capital gained during the first stage to join a group of up to 40 players to partake in high-end or endgame content.

  4. The Neural Circuitry of Expertise: Perceptual Learning and Social Cognition

    Directory of Open Access Journals (Sweden)

    Michael eHarre

    2013-12-01

    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. 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 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 likely 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 behaviourally 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. Using techniques that have been developed in mathematical psychology, I show that we can represent some of the key features of expertise using stochastic differential equations. 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

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

    Science.gov (United States)

    Bishop, Laura; Goebl, Werner

    2014-01-01

    Ensemble musicians exchange auditory and visual signals that can facilitate interpersonal synchronization. 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 clarinetists, 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 synchronized. The range of asynchronies most often endorsed as synchronized 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.

  7. A sociological analysis of ethical expertise: The case of bioethics

    Directory of Open Access Journals (Sweden)

    Nathan Emmerich

    2016-12-01

    Full Text Available This paper examines the question of ethical expertise and does so in the context of bioethics or, more accurately, applied ethics and the ethical governance of the life sciences. This analysis builds on a perspective set out in a previous paper and develops it further such that it relates to democratic processes. I argue that the academic practice of applied ethics exhibits a particular logic, way of thinking or eidos. Drawing on work in the history of science I present the logic of this practice as underpinned by a particular set of values or ethos. This can be contrasted with what Bernstein calls the democratic ethos as well as that of everyday moral agents. Using the framework of expertise developed by Collins and Evan’s—which differentiates between ubiquitous, contributory, and interactional expertise—I suggest that (bioethicists should modulate their expertise depending on the particular nature of the fora—academic, public, and policy-making—they are speaking in.

  8. Assessing expertise in introductory physics using categorization task

    Directory of Open Access Journals (Sweden)

    Andrew Mason

    2011-10-01

    Full Text Available The ability to categorize problems based upon underlying principles, rather than surface features or contexts, is considered one of several proxy predictors of expertise in problem solving. With inspiration from the classic study by Chi, Feltovich, and Glaser, we assess the distribution of expertise among introductory physics students by asking three introductory physics classes, each with more than a hundred students, to categorize mechanics problems based upon similarity of solution. We compare their categorization with those of physics graduate students and faculty members. To evaluate the effect of problem context on students’ ability to categorize, two sets of problems were developed for categorization. Some problems in one set included those available from the prior study by Chi et al. We find a large overlap between calculus-based introductory students and graduate students with regard to their categorizations that were assessed as “good.” Our findings, which contrast with those of Chi et al., suggest that there is a wide distribution of expertise in mechanics among introductory and graduate students. Although the categorization task is conceptual, introductory students in the calculus-based course performed better than those in the algebra-based course. Qualitative trends in categorization of problems are similar between the non-Chi problems and problems available from the Chi study used in our study although the Chi problems used are more difficult on average.

  9. Anticipatory Governance: Bioethical Expertise for Human/Animal Chimeras

    Harvey, Alison; Salter, Brian

    2012-01-01

    The governance demands generated by the use of human/animal chimeras in scientific research offer both a challenge and an opportunity for the development of new forms of anticipatory governance through the novel application of bioethical expertise. Anticipatory governance can be seen to have three stages of development whereby bioethical experts move from a reactive to a proactive stance at the edge of what is scientifically possible. In the process, the ethicists move upstream in their engagement with the science of human-to-animal chimeras. To what extent is the anticipatory coestablishment of the principles and operational rules of governance at this early stage in the development of the human-to-animal research field likely to result in a framework for bioethical decision making that is in support of science? The process of anticipatory governance is characterised by the entwining of the scientific and the philosophical so that judgements against science are also found to be philosophically unfounded, and conversely, those activities that are permissible are deemed so on both scientific and ethical grounds. Through what is presented as an organic process, the emerging bioethical framework for human-to-animal chimera research becomes a legitimating framework within which ‘good’ science can safely progress. Science gives bioethical expertise access to new governance territory; bioethical expertise gives science access to political acceptability. PMID:23576848

  10. Musical expertise and the ability to imagine loudness.

    Directory of Open Access Journals (Sweden)

    Laura Bishop

    Full Text Available 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.

    The change in software language and methodology by CDF and D0 to object-oriented from procedural Fortran is significant. Both experiments requested dedicated expertise that could be applied to software design, coding, advice and review. The Fermilab Run II offline computing outside review panel agreed strongly with the request and recommended that the Fermilab Computing Division hire dedicated OO expertise for the CDF/D0/Computing Division joint project effort. This was done and the two experts have been an invaluable addition to the CDF and D0 upgrade software projects and to the Computing Division in general. These experts have encouraged common approaches and increased the overall quality of the upgrade software. Advice on OO techniques and specific advice on C++ coding has been used. Recently a set of software reviews has been accomplished. This has been a very successful instance of a targeted application of computing expertise, and constitutes a very interesting study of how to move toward modern computing methodologies in HEP

    2011-07-12

    This paper analyses how the changing governance of animal health has impacted upon veterinary expertise and its role in providing public health benefits. It argues that the social sciences can play an important role in understanding the nature of these changes, but also that their ideas and methods are, in part, responsible for them. The paper begins by examining how veterinary expertise came to be crucial to the regulation of the food chain in the twentieth century. The relationship between the veterinary profession and the state proved mutually beneficial, allowing the state to address the problems of animal health, and the veterinary profession to become identified as central to public health and food supply. However, this relationship has been gradually eroded by the application of neoliberal management techniques to the governance of animal health. This paper traces the impact of these techniques that have caused widespread unease within and beyond the veterinary profession about the consequences for its role in maintaining the public good of animal health. In conclusion, this paper suggests that the development of the social sciences in relation to animal health could contribute more helpfully to further changes in veterinary expertise.

    2016-01-01

    Musical expertise entails meticulous stylistic specialisation and enculturation. Even so, research on musical training effects has focused on generalised comparisons between musicians and non-musicians, and cross-cultural work addressing specialised expertise has traded cultural specificity and sensitivity for other methodological limitations. This study aimed to experimentally dissociate the effects of specialised stylistic training and general musical expertise on the perception of melodies. Non-musicians and professional musicians specialising in classical music or jazz listened to sampled renditions of saxophone solos improvised by Charlie Parker in the bebop style. Ratings of explicit uncertainty and expectedness for different continuations of each melodic excerpt were collected. An information-theoretic model of expectation enabled selection of stimuli affording highly certain continuations in the bebop style, but highly uncertain continuations in the context of general tonal expectations, and vice versa. The results showed that expert musicians have acquired probabilistic characteristics of music influencing their experience of expectedness and predictive uncertainty. While classical musicians had internalised key aspects of the bebop style implicitly, only jazz musicians' explicit uncertainty ratings reflected the computational estimates, and jazz-specific expertise modulated the relationship between explicit and inferred uncertainty data. In spite of this, there was no evidence that non-musicians and classical musicians used a stylistically irrelevant cognitive model of general tonal music providing support for the theory of cognitive firewalls between stylistic models in predictive processing of music.

  17. Instructional Design for Accelerated Macrocognitive Expertise in the Baseball Workplace

    Peter J. Fadde

    2016-03-01

    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

    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, the cooperating team

    The EU has set the goal for the use of renewable energy at 20 percent by the year 2020. The Finnish national goal is 38 percent. This goal has set new challenges for entrepreneurs who are working in the field of bioenergy. Bioenergy is developing all the time and because of this new information should be passed on to persons who are working in the field of bioenergy continuously. Seinajoki University of Applied Sciences (School of Forestry and Agriculture) implemented the bioenergy expertise project (Bioenergia-asiantuntijuuden kehittaeminen tyoeelaemaelaehtoeisesti) during the years 2009 - 2012 in Southern Ostrobothnia of Finland. The bioenergy expertise project developed the Learning Environment in the field of bioenergy, formed a bioenergy professionals' network, activated the bioenergy entrepreneur network, implemented the report on the future needs of bioenergy education, tested and piloted a reference model for information collection using mobile systems with the bioenergy actors, and arranged bioenergy themed events. The Learning Environment can be used to meet the needs of the University of Applied Sciences and by the entrepreneurs in the area. The bioenergy professionals' network is a group of professionals who work in the area of Southern Ostrobothnia. Bioenergy themed events attracted a lot of participants, but the most popular events were the bioenergy fairs, which were arranged in Tuomarniemi and Kurejoki. The arranged events were also useful from the entrepreneurs networking point of view. The bioenergy expertise project was overall a success and the feedback was positive. The permanent results of the project are publications, reports, the bioenergy professionals' network and the new Learning Environment. Seinajoki University of Applied Sciences is hosting the Learning Environment. The bioenergy professionals' network is continuing its activities in Jarvikilta network of professionals, which also have activities in the area of

Nous nous interrogeons sur les contenus à enseigner et les situations possibles à mettre en oeuvre dans les classes pour que des élèves construisent une conception scientifique du vivant. Nous délimitons d’abord le concept de vivant dans une perspective d’enseignement à de jeunes élèves. Puis nous identifions un des enjeux de l’enseignement-apprentissage du vivant : permettre aux élèves de construire un autre rapport au vivant que celui de la vie de tous les jours. Nous abordons les situations scolaires comme des processus d’acculturation scientifique scolaire. Les élèves sont en effet incités à entrer dans une culture scientifique en s’appropriant à la fois des savoirs relatifs au vivant et des pratiques de la biologie. À partir de deux séquences d’enseignement réalisées en CP puis en CE1 avec les mêmes élèves, nous repérons des indicateurs qui témoignent de la construction d’une conception scientifique du vivant par les élèves. Nous montrons également que les processus d’acculturation scientifique dans lesquels les élèves sont engagés ont des effets sur leur développement.

    Mental imagery in experts has been documented in visual arts, music and dance. Here, we examined this issue in an understudied art domain, namely, culinary arts. Previous research investigating mental imagery in experts has reported either a stronger involvement of the right hemisphere or bilateral brain activation. The first aim of our study was to examine whether culinary arts also recruit such a hemispheric pattern specifically during odor mental imagery. In a second aim, we investigated whether expertise effects observed in a given sensory domain transfer to another modality. We combined psychophysics and neurophysiology to study mental imagery in cooks, musicians and controls. We collected response times and event-related potentials (ERP) while participants mentally compared the odor of fruits, the timbre of musical instruments and the size of fruits, musical instruments and manufactured objects. Cooks were faster in imagining fruit odors, and musicians were faster in imagining the timbre of musical instruments. These differences were not observed in control participants. This expertise effect was reflected in the ERP late positive complex (LPC): only experts showed symmetric bilateral activation, specifically when cooks imagined odors and when musicians imagined timbres. In contrast, the LPC was significantly greater in the left hemisphere than in the right hemisphere for non-expert participants in all conditions. These findings suggest that sensory expertise does not involve transfer of mental imagery ability across modalities and highlight for the first time that olfactory expertise in cooks induces a balance of activations between hemispheres as does musical expertise in musicians. © 2017 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

  8. How Well Do Computer-Generated Faces Tap Face Expertise?

    Directory of Open Access Journals (Sweden)

    Kate Crookes

    Full Text Available The use of computer-generated (CG stimuli in face processing research is proliferating due to the ease with which faces can be generated, standardised and manipulated. However there has been surprisingly little research into whether CG faces are processed in the same way as photographs of real faces. The present study assessed how well CG faces tap face identity expertise by investigating whether two indicators of face expertise are reduced for CG faces when compared to face photographs. These indicators were accuracy for identification of own-race faces and the other-race effect (ORE-the well-established finding that own-race faces are recognised more accurately than other-race faces. In Experiment 1 Caucasian and Asian participants completed a recognition memory task for own- and other-race real and CG faces. Overall accuracy for own-race faces was dramatically reduced for CG compared to real faces and the ORE was significantly and substantially attenuated for CG faces. Experiment 2 investigated perceptual discrimination for own- and other-race real and CG faces with Caucasian and Asian participants. Here again, accuracy for own-race faces was significantly reduced for CG compared to real faces. However the ORE was not affected by format. Together these results signal that CG faces of the type tested here do not fully tap face expertise. Technological advancement may, in the future, produce CG faces that are equivalent to real photographs. Until then caution is advised when interpreting results obtained using CG faces.

  9. Public scientific expertise and judicial risks: the case of radon

    International Nuclear Information System (INIS)

    Massuelle, M.H.

    2000-01-01

    In France, radon has emerged as a public health issue mainly at the initiative of scientists. Even if public authorities have set up an embryo of regulations, for a long time scientists faced the radon issue alone, in producing knowledge, informing about their results, providing advice to public authorities, various bodies and individuals, and in participating in the process of technical standardisation. These functions are identified in the paper in order to sketch out a typology of different situations, formal and informal, in which researchers transformed into experts are called to collaborate. During their missions, experts are exposed to 'judicial risks', particularly in terms of civil liability or 'professional' responsibility and even criminal responsibility. They face legal difficulties because of the lack of a legal framework for public scientific expertise. The situation is confused: there is a growing will to involve scientific experts in decision-making in the field of public health, especially when the precautionary principle is at stake, and in parallel, no real materialisation of this expertise in terms of regulations, which puts on experts' shoulders some new responsibilities. Moreover we can observe a generalised increase in the attribution of blame and penal responsibility in French society which make the position of all actors involved more uncomfortable. We know that radon, as a domestic risk, is particular in many ways. Nevertheless, it can be used in an analysis of scientists' roles/actions and of the legal difficulties they face, to illustrate appropriately the problems that arise as expertise is developed about new risks.

    Neurological disorders are increasingly recognised as a major public health problem, especially in the developing world. Having adequate neurology expertise to tackle this issue is essential. A 17-item survey was conducted to gather information about the number, training and location of neurologists and supportive facilities available to them in the 16 middle- and high-income Arab countries. Data about the availability of postgraduate training programmes was collected. Surveys were returned from all targeted countries. The population per neurologist ranges from 35,000 to just over two million, and the most neurologists are based in large cities. Most of the practising neurologists had received extensive training in neurology and/or passed specialty exams. The majority had all or part of their training abroad. Neuro-radiological and neuro-physiological investigations are generally available in most surveyed countries but neuro-genetics and neuro-immunology services are lacking. Neurology training programmes are available in ten Arab countries with a total of 504-524 trainees. The availability of neurologists, supportive services and training programmes varies between Arab countries. Further development of neurology expertise and local training programmes are needed.

    This document first presents the opinion of the Anses (the French National Agency for food, environment and work safety) about the assessment of the exposure to electromagnetic fields emitted by communicating meters. This opinion and some associated recommendations are based on the content of the study report which is thereafter presented. This report first proposes a presentation of the context, objective, implemented method and organisation of this study, and a focus on how interest conflicts have been avoided. The next chapters presents some other aspects related to the deployment of these meters: European and French legal framework, normative framework, historical overview and current status of this deployment in France, in the European Union and abroad. The report also addresses and comments some controversies about these meters: the public controversy about Linky in France (literature overview, nature and actors of the controversy, dynamics about health issue), a legal conflict about the ownership and management of the Linky meters in France, and a case of controversy in Quebec (Canada). Technical descriptions of different communicating meters are then presented: Linky with the CPL or PLC technology, and Gazpar and water meters using a radio technology. The authors report measurements performed by EDF, public bodies and other actors, and also measurements performed in Finland of the exposure in the case of PLC meters, radio-wave-based meters and concentrators. Based on these exposure data, an assessment of health effect is proposed, followed by conclusions and recommendations

    2010-12-01

    Becoming proficient at navigation in urban environments is something that we all aspire to. Here we asked whether being an expert at wayfinding in one environment has any effect on learning new spatial layouts. Licensed London taxi drivers are among the most proficient urban navigators, training for many years to find their way around a complex and irregularly-laid out city. We first tested how well they could learn the layout of an unfamiliar town compared with a group of non-taxi drivers. Second, we investigated how effectively taxi drivers could integrate a new district into their existing spatial representation of London. We found that taxi drivers were significantly better than control participants at executing routes through the new town, and representing it at a map-like survey level. However, the benefits of navigational expertise were not universal. Compared with their performance in the new town, taxi drivers were significantly poorer at learning the layout of a new area that had to be integrated with their existing knowledge of London. We consider reasons for this picture of facilitation and limitation, in particular drawing parallels with how knowledge acquisition occurs in the context of expertise in general.

Thephenomenon of the transfer of verbalized operational senses (VOS is analyzedand is investigated on the basis of the sense theory of thinking, as proposed byTikhomirov (1969, 1984.It is shown that VOS transfer manifests itself in diverse forms. It seems to be dependenton the factors of chess position and the age and skill level of the player.Diverse forms of transferring are associated with a change in separate indices ofVOS volume, structure, depth, and degree of consciousness in a connected position.VOS transfer is found more in skilled than in unskilled chess players; skilledplayers demonstrate selectivity of search in a connected position. VOS transfer isassociated not simply with the repetition and copying of some forecasts, whichgive the direction of search, but also with using and transforming the results ofprevious verbal searches.

    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.

  19. Experiencing art: the influence of expertise and painting abstraction level

    Elina ePihko

    2011-09-01

    Full Text Available 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 aesthetic judgments and emotional evaluations, gaze patterns, and electrodermal reactivity between the two groups of participants. The level of abstraction affected aesthetic judgments and emotional valence ratings of the laypersons but had no effect on the opinions of the experts: the laypersons’ aesthetic 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.

  20. 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).

    Reid Lyon, G; Weiser, Beverly

    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.

    Full text of publication follows: SITEX is a 24-month FP7 project led by IRSN and bringing together 15 organisations representing technical safety organisations (TSO) and safety authorities, as well as civil society outreach specialists involved in the 'regulatory' review process of geological disposal of radioactive waste. SITEX aims at establishing the conditions required for developing a sustainable network of experts from various horizons (authorities, TSO, academic organisations, civil society,...) capable of developing and coordinating the technical expertise that is required from the stakeholders in charge of delivering opinion, independently from the waste management organisations (WMO), on the safety of geological disposals. The SITEX programme of work is split into a set of six work packages that address technical and organisational issues allowing to propose a structure of the missions and operating mode of the future network. These issues relate on the one hand to the study of the potential for sharing and developing technical expertise practices amongst stakeholders, on the other hand on the ability to implement co-ordinated R and D programmes run by TSO in order to develop the scientific knowledge necessary to perform independent technical assessments. Two major perspectives are identified for the future of the SITEX network: its ability to foster co-operation between regulatory bodies, TSO, implementers and civil society with a view to enhancing common understanding of key safety issues and challenges and to identifying possible harmonisation of practices; the constitution of a scientific task force (mainly driven by TSO) for research definition and implementation at the European level allowing to improve the co-ordination of scientific programmes between TSO and developing its own skills and analytical tools, independently of the WMO. A comprehensive list of safety issues relevant to the development and implementation of a geological repository has

    Joint-improvisation is not only an open-ended creative action that two or more people perform together in the context of an artistic performance (e.g., theatre, music or dance). Joint-improvisation also takes place in daily life activities when humans take part in collective performance such as toddlers at play or adults engaged in a conversation. In the context of this article, joint-improvisation has been looked at from a social motor coordination perspective. In the literature, the nature of the social motor coordination characteristics of joint-improvisation for either the creative aspect or daily life features of this motor performance remains unclear. Additionally, both solo-improvisation and joint-improvisation need to be studied conjointly to establish the influence of the social element of improvisation in the emergence of multi-agent motor coordination. In order to better understand those two types of improvisation, we compared three level of expertise - novice, intermediate and professional in dance improvisation to identify movement characteristics for each of the groups. Pairs of the same level were asked to improvise together. Each individual was also asked to perform an improvisation on his/her own. We found that each of the three groups present specific movement organization with movement complexity increasing with the level of expertise. Experts performed shorter movement duration in conjunction with an increase range of movement. The direct comparison of individual and paired Conditions highlighted that the joint-improvisation reduced the complexity of the movement organization and those for all three levels while maintaining the differences between the groups. This direct comparison amongst those three distinct groups provides an original insight onto the nature of movement patterns in joint-improvisation situation. Overall, it reveals the role of both individual and collective properties in the emergence of social coordination.

    Svitak, F.

    1997-01-01

    The SKODA Nuclear Machinery company is a major manufacturer of nuclear reactor assemblies and supplier of WWER type primary coolant circuits. In the past, the company was nearly a monopolistic manufacturer of WWER reactor assemblies supplied to the Central and East European countries (except the USSR) grouped in the former Council of Mutual Economic Assistance. Over the 1980-1993 period, 21 units of the WWER-440 type and 3 units of the WWER-1000 type were manufactured. The company keeps abreast of technological progress and has been switching to new manufacturing areas, such as compact storage racks for spent fuel pools, hermetic cable bushings, spent fuel storage and transport casks, and cooperation in the manufacture of neutron flux measuring channels. Technological services provided to nuclear power plants constitute another important field of the company's business. The company's combined expertise in Soviet and Western designed PWRs is a considerable asset. (P.A.)

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

    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.

    All healthy organizations generate and use knowledge. As organizations interact with their environments, they absorb information, turn it into knowledge and take action based on it in combination with their experiences, values and internal rules. Without knowledge, an organization could not organize itself; it would be unable to maintain itself as a functioning enterprise. Like any highly technical endeavor, the use of nuclear technology relies heavily on a vast accumulation of knowledge - volumes of scientific research, engineering analysis, operational data, regulatory reviews and many other types of technical information - combined with a complex assortment of people with the requisite educational background, expertise and acquired insight to apply that body of knowledge safely and effectively. Methods must be found to better capture this enormous body of nuclear experience. Today's nuclear workforce needs to document knowledge and then mentor the new nuclear scientists to build upon it, rather than having to re-create it. The latest studies have shown that at present NPPs cannot be replaced by other kinds of electric sources and in no case by renewable ones in an efficient manner. Therefore it is necessary to carefully manage knowledge gathered in the nuclear field during the years and to keep on the nuclear safety research, education and training to ensure and upgrade safe and reliable operation of existing and future nuclear facilities. Having in mind the complexity of this issue of global concern, this presentation tries to provide a brief overview of what knowledge management is and how it can help organizations to preserve knowledge, skills and expertise, particularly for the nuclear environment. What are the challenges of nuclear knowledge management and who should lead knowledge management efforts are also some of the issues covered in the presentation. (authors)

  19. Nuclear energy: from scientist mobilisation to the rise of counter-expertise

    International Nuclear Information System (INIS)

    Topcu, Sezin

    2006-01-01

    The management of nuclear energy in France was restricted until the mid 1970's to a small circle of government experts. Within the scientific community criticism against nuclear power mostly targeted nuclear weapons while the sphere of civil nuclear energy remained unchallenged. The launch of the French nuclear programme in 1974 led to the first protest against civil nuclear power and its management within the scientific community. The mobilisation of thousands of researchers against the programme, initially through a petition, the so-called 'Appeal of the 400', then through the creation of an association, the 'Group of Scientists for Information on Nuclear Energy (GSIEN)', beside reflecting a rupture in the relations with science, progress and decision-making processes in the nuclear field, also expressed in the following decades the appropriation of critical knowledge on nuclear risks by the actors of non-governmental organisations. The criticism raised by scientists in 1975 therefore underlies two major shifts between the 1950's to 1990's in collective action vis-a-vis nuclear risk: from the mobilisation of 'distinguished scientists' against the atom bomb in the 1950's and 1960's (Joliot, Russell, Einstein, Rostand) to the politicisation of nuclear power by 'critical scientists' in the post-May 1968 period (GSIEN) and finally, after the Chernobyl accident, to the rise of associations of counter-expertise on nuclear energy (creation of expert NGOs such as the Commission for Independent Research and Information on Radioactivity-CRIIRAD and the Association for the Control of Radioactivity in the West-ACRO). This paper examines the crucial role that the community of physicists has played in transforming the relations between scientists, science, expertise and society

    Full Text Available Du fait de leurs bonnes connaissances des espèces et des milieux et de la mise en place de protocoles de suivi à grande échelle et sur le long terme, les réseaux associatifs naturalistes disposent de bases de données fiables, précieuses pour les scientifiques. Ainsi, dans cette étude, la valorisation d’une importante base de données de présence d’amphibiens via la modélisation de leur niche écologique a permis d’établir des cartes de répartition potentielle de quatre espèces protégées en France : le crapaud calamite, le triton crêté, la rainette arboricole et la rainette méridionale dans six départements français. Les résultats acquis permettront non seulement de mieux comprendre la biologie et l’écologie des espèces mais aussi d’aider à l’élaboration de plans d’actions de conservation dans les territoires concernés.

    The aim of this study was to search for oculomotor correlates of expertise in visual arts, in particular with regard to paintings. Achieving this goal was possible by gathering data on eye movements of two groups of participants: experts and non-experts in visual arts who viewed and appreciated the aesthetics of paintings. In particular, we were interested in whether visual arts experts more accurately recognize a balanced composition in one of the two paintings being compared simultaneously, and whether people who correctly recognize harmonious paintings are characterized by a different visual scanning strategy than those who do not recognize them. For the purposes of this study, 25 paintings with an almost ideal balanced composition have been chosen. Some of these paintings are masterpieces of the world cultural heritage, and some of them are unknown. Using Photoshop, the artist developed three additional versions of each of these paintings, differing from the original in the degree of destruction of its harmonious composition: slight, moderate, or significant. The task of the participants was to look at all versions of the same painting in pairs (including the original) and decide which of them looked more pleasing. The study involved 23 experts in art, students of art history, art education or the Academy of Fine Arts, and 19 non-experts, students in the social sciences and the humanities. The experimental manipulation of comparing pairs of paintings, whose composition is at different levels of harmony, has proved to be an effective tool for differentiating people because of their ability to distinguish paintings with balanced composition from an unbalanced one. It turned out that this ability only partly coincides with expertise understood as the effect of education in the field of visual arts. We also found that the eye movements of people who more accurately appreciated paintings with balanced composition differ from those who more liked their altered

    I4CE - the Institute for Climate Economics is an initiative of the Caisse des Depots, which continues to support it, and the Agence Francaise de Developpement, which has joined this project, giving the Institute a strong international dimension. The two major French public financial institutions are thus joining forces to create a real think tank, open to other partnerships. From the outset, I4CE benefits from the expertise and reputation which CDC Climat Research has acquired over ten years through its publicly available research, its discussions with public and private decision makers, and its research partnerships with other teams in France, Europe and around the world. I4CE aims at strengthening this independent economic expertise and increasing its influence. The creation of I4CE in 2015 is a step towards creating an agenda of solutions for the climate. I4CE hopes that its work will feed into efforts by France and international negotiators to reach an agreement in Paris in December 2015. However, I4CE has long believed that the transition towards a 'de-carbonised' economy which is resilient to climate change does not depend solely upon work by governments. I4CE believes that three other categories of stakeholders are just as essential for ensuring that this change is successful: - the industrial sector, and the energy sector in particular, the speed of transformation of which will depend greatly upon the inclusion of a carbon price in its model; - the finance sector which now must incorporate the 2 deg. C objective into the way in which it allocates capital; - regional stakeholders which decide on the future of cities, agriculture and forestry. I4CE has developed and organised its research programme for the coming years around these three areas, with the aim of providing its partners with the keys to understanding and decision making, acting as a meeting point for the best academic work and the constraints of political and economic action.

    2013-10-01

    Neonaticide is the term used to refer to the killing of newborn infants within the first 24 hours of life. A recent study conducted by Inserm Unit 750 found a frequency of 2.1 cases of neonaticide for 100,000 births in France. The persistence of these crimes raises serious issues, and scientists have attempted to explain this by the profile of neonaticidal mothers: young, or even teenage, single, primiparous, and socially deprived. The present study sought to question this profile, and to suggest a new profile for neonaticidal mothers. This retrospective study over the years 1996-2000 comprised 32 cases of neonaticide perpetrated in three French regions. Seventeen solved cases of these 32 cases generated 54 documents by expert consultants, mainly psychiatric and psychological expertise, studied and analysed here using Modalisa software for quantitative analyses and Nvivo software for qualitative data. No single socio-demographic profile was observed. The mothers were in contrasting situations at the time of the event. There were few psychotic profiles. The other psychopathological disturbances detected were very often related to the event. The most surprising feature in the expert reports describing the neonaticidal mothers was the existence of what we have termed "descriptive absent-factors". These mothers had not experienced major trauma in childhood such as the death of persons close or foster care. They were not living in an environment of family violence. They did not exhibit addictive or self-harm behaviour. Their parents before them had similar profiles, except three cases of alcoholism. Their parentage, and that of the infants, was not an issue. The most widely described personality features were immaturity, dependency on others, withdrawal, inhibition, emptiness, lack of affectivity, non-expressiveness, and devaluation of self-image. The very impoverished relational environment of these mothers also appears in the expertise data. Their affective and

  5. Managing nuclear knowledge and expertise - An industry perspective

    Garderet, Ph.

    2002-01-01

    Full text: The industrial demand for expertise and qualified personnel in nuclear sciences and technologies will obviously continue to be strong during the next decades: in all cases, a high level of competence will necessarily continue to be required to maintain high performances in operating current nuclear facilities (up to decommissioning) ; moreover, additional skills are to be engaged to conceive new projects or to propose new services for new industrial customers. The industrial needs evidently show some quantitative or qualitative specificities according to the strategy each country has adopted in the past or is adopting now for the use of nuclear power or other nuclear technologies. But the general trends concerning the access to qualified knowledge in nuclear sciences and technologies are globally the same, so concrete actions have to be taken as soon as possible to anticipate difficult situations and overcome the problems. In the countries where nuclear industry has been strongly developed during the past decades (for example France) the problem chiefly concerns the relative ageing of the human workforce and the ability to maintain the accumulated knowledge and replace technical expertise at the very moment when all the technological companies show a significant decline in the number of entrants in all the domain of science and engineering. The problem is reinforced by the fact that (strictly for the same reasons) this phenomenon is observed concurrently within the research laboratories, among the staff of the safety authorities and, more generally, in all the offices engaged in the decision making process about nuclear affairs. Part of the solution to these serious problems stands in the human resources policy that the main nuclear industries have to achieve : internal training through enterprise universities, auto-formation, tutorage of young scientists by seniors, programs of knowledge preservation, international mobility when possible.

  7. Hello World! - Experiencing Usability Methods without Usability Expertise

    Science.gov (United States)

    Eriksson, Elina; Cajander, Åsa; Gulliksen, Jan

    How do you do usability work when no usability expertise is available? What happens in an organization when system developers, with no previous HCI knowledge, after a 3-day course, start applying usability methods, and particularly field studies? 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.

    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.

    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.

    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.

The specific activities involved in the ORO/TOPO include procurement, operational testing, inspection, logistics, interfaces, maintenance, management and improvements, and system operation. Oak Ridge Associated Universities (ORAU) has developed (and will maintain and enhance) a data base of sources of transportation expertise in selected technical areas for ORO. The data base includes individuals and organizations who have indicated that they have capabilities and interest in assisting ORO in the design, development, implementation, and management of the OCRWM transportation system. This assistance might be in the form of consulting or subcontract work and/or participation in peer review panels, technical evaluation committees, workshops, advisory groups, etc. This initial project was completed in the four month period of January 30, 1987 through May 31, 1987

    1984-05-01

    This report represents the conclusions of a project studying the role of engineering expertise on shift in nuclear power plants. Using the present shift technical advisor (STA) position as the base case, several alternatives are analyzed. On-shift alternatives included the STA, the SS (shift supervisor), and the SE (shift engineer). The SE is degreed, experienced, trained, and licensed as a Senior Reactor Operator. Some non-shift alternatives were also studied. These included a cadre of on-call engineers and specialists within continual contact and easy reach of the plant; a technical system of phone and data lines linking the plant with a facility similar to an on-site technical support center; and finally, an SPDS (safety parameter display system) to agument technical upgrading of operator aids presently available. Potential problems considered in the analysis of implementation of these alternatives included job content constraints, problems of crew acceptance, and problems of labor supply and retention. Of the considered alternatives, the SE and SS options appear superior to the current STA approach. The SE approach appears the easiest to implement and the most effective under varied plant conditions. The SE may also serve as liaison to off-site support facilities

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

    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.

  14. In-service training and expertise requirements in radiation protection

    2003-01-01

    Proper selection of staff and their special education and training in radiation protection are important factors when assuring faultless man-machine interaction and thereby a reduced likelihood of human factor failure in hazardous practices. University-level institutions can only provide education in the individual partial segments of the multidisciplinary area of radiation protection, whereas the proper practices are learned by graduate personnel on the job, by performing operational tasks at their particular workplace. The scope o expertise of subjects providing radiation protection surveillance and the requirements for their special education and training are outlined. Supervising persons appointed by the radiation source handling licensee to perform a number of operational tasks at the workplace assume a prominent position. Alternatively, systematic supervision at the workplace can be contracted by the licensee from an external body, provided that the latter has acquired appropriate licence from the State Office for Nuclear Safety. The provisions of the Atomic Act and the related implementing regulations with respect to special training and to the examination of professional competence before an expert commission are briefly outlined.

    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.

    2016-12-01

    In this article, we clarify and describe the nature of nursing expertise and provide a framework to guide its identification and further development. To have utility and rigour, concept-driven research and theories of practice require underlying concepts that are robust, valid and reliable. Advancing understanding of a concept requires careful attention to explicating its knowledge, metaphors and conceptual meaning. Examining the concepts and metaphors of nursing expertise, and how they have been interpreted into the nursing discourse, we aimed to synthesise definitions and similarities between concepts and elicit the defining characteristics and properties of nursing expertise. In clarifying the concept, we sought to move beyond the ambiguity that currently surrounds expertise in nursing and unravel it to make explicit the characteristics of nursing expertise from published peer-reviewed studies and structured literature synthesis. Findings indicate a lack of clarity surrounding the use of the term expertise. Traditional reliance upon intuition as a way of explaining expert performance is slowly evolving. Emerging from the analysis is a picture of expertise as the relationship between networks of contextual reasoning, understanding and practice. Striking absences in the discourse include limited explication of ethical reasoning and theorising a broader interpretation of expertise reflective of contemporary forms of nursing. © 2016 John Wiley & Sons Ltd.

    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.

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

    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.

    1983-02-01

    This report describes the practices of selected foreign countries with providing engineering expertise on shift in nuclear power plants. The extent to which engineering expertise is made available and the alternative models of providing such expertise are presented. The implications of foreign practices for US consideration of alternatives are discussed, with reference to the shift technical advisor (STA) position and to a proposed shift engineer position. The procedure used to obtain information on foreign practices was primarily a review of the literature, including publications, presentations, and government and utility reports. There are two approaches that are in use to make engineering expertise available on shift: (1) employing a graduate engineer in a line management operations position; and (2) creating a specific engineering position for the purpose of providing expertise to the operations staff

  9. La loi de la gravitation universelle Newton, Euler et Laplace Le cheminement d’une révolution scientifique vers une science normale

    CERN Document Server

    Schroeder, Prosper

    2007-01-01

    La Philosophiae Naturalis Principia Mathematica de Newton (1686), marquait-elle le début d'une révolution scientifique, ou était-elle la simple synthèse des idées d'un Kepler, Galilée ou Hooke? Une analyse des idées de Newton écarte cette hypothèse par le simple fait que les Principia cherchaient à démontrer la fausseté des approches antérieures. Pourtant, Newton subit un échec dans l'application de sa théorie de la gravitation à l'explication du mouvement de la Lune, échec qui marqua le développement de la mécanique céleste pendant tout le 18e siècle. Clairaut, d'Alembert et Euler doutaient de la validité de la loi newtonienne presque en même temps et leurs idées firent progresser la mécanique céleste qui atteignit l'état de «science normale» avec Le traité de mécanique céleste de Laplace, un siècle après Newton. Cet ouvrage relate cet épisode de l'histoire des sciences exactes au 18e siècle et fournit un exemple des théories épistémologiques toujours en vigueur aujourd...

    2010-08-15

    In normal operating conditions the LHC detectors are expected to record about 10{sup 10} collisions each year. The processing of all the consequent experimental data is a real computing challenge in terms of equipment, software and organization: it requires sustaining data flows of a few 10{sup 9} octets per second and recording capacity of a few tens of 10{sup 15} octets each year. In order to meet this challenge a computing network implying the dispatch and share of tasks, has been set. The W-LCG grid (World wide LHC computing grid) is made up of 4 tiers. Tiers 0 is the computer center in CERN, it is responsible for collecting and recording the raw data from the LHC detectors and to dispatch it to the 11 tiers 1. The tiers 1 is typically a national center, it is responsible for making a copy of the raw data and for processing it in order to recover relevant data with a physical meaning and to transfer the results to the 150 tiers 2. The tiers 2 is at the level of the Institute or laboratory, it is in charge of the final analysis of the data and of the production of the simulations. Tiers 3 are at the level of the laboratories, they provide a complementary and local resource to tiers 2 in terms of data analysis. (A.C.)

  11. Moral Expertise in the Clinic: Lessons Learned from Medicine and Science.

    2016-08-01

    Philosophers and others have questioned whether or not expertise in morality is possible. This debate is not only theoretical, but also affects the perceived legitimacy of clinical ethicists. One argument against moral expertise is that in a pluralistic society with competing moral theories no one can claim expertise regarding what another ought morally to do. There are simply too many reasonable moral values and intuitions that affect theory choice and its application; expertise is epistemically uniform. In this article, we discuss how similar concerns have recently threatened to undermine expertise in medicine and science. In contrast, we argue that the application of values is needed to exercise medical, scientific, and moral expertise. As long as these values are made explicit, worries about a pretense to authority in the context of a liberal democracy are ill-conceived. In conclusion, we argue for an expertise that is epistemically diverse. © The Author 2016. Published by Oxford University Press, on behalf of the Journal of Medicine and Philosophy Inc.

    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.

  13. Changing the Way Archaeologists Work: blogging and the development of expertise

    Directory of Open Access Journals (Sweden)

    Sara Perry

    2015-05-01

    Full Text Available While blogging in archaeology has a genealogy that can be traced back nearly two decades, the relationship between such practice and the constitution of disciplinary expertise has barely been probed. Arguably directly relatable to early web-based efforts to reconfigure the archaeological interpretative process and redefine professional identity (e.g. as evidenced in Cornelius Holtorf's 1998 hypermediated PhD dissertation, blog work has long been drawn into the exercise of crafting skilled bodies and accredited knowledge bases. In the last 10 years, however, it has increasingly been applied to the academic classroom, where it is used as a formal teaching tool at all levels of university education. The implications of this pedagogical phenomenon are profound, yet the epistemological consequences for the professionalisation of archaeology are hardly understood. Here I combine a critical analysis of students' experiments with blogging in my own undergraduate archaeology courses with an overview of comparable classroom-based and professional weblog work elsewhere. I draw upon evidence collected through survey, interviews, course assessments and reflective reports to make a case not only for blogging as a meaningful creative exercise, but as a mechanism by which the very nature of archaeology itself can be prodded, extended and perhaps even fundamentally reconfigured. Although often fraught with tension, blog work is an influential intellectual tool for the discipline. I outline here how it promises both to narrow the gap between archaeological theory and practice, and simultaneously to hone and empower emerging professionals.

  14. Rapid knowledge assessment (RKA): Assessing students content knowledge through rapid, in class assessment of expertise

    Science.gov (United States)

    O'Connell, Erin

    Understanding how students go about problem solving in chemistry lends many possible advantages for interventions in teaching strategies for the college classroom. The work presented here is the development of an in-classroom, real-time, formative instrument to assess student expertise in chemistry with the purpose of developing classroom interventions. The development of appropriate interventions requires the understanding of how students go about starting to solve tasks presented to them, what their mental effort (load on working memory) is, and whether or not their performance was accurate. To measure this, the Rapid Knowledge Assessment (RKA) instrument uses clickers (handheld electronic instruments for submitting answers) as a means of data collection. The classroom data was used to develop an algorithm to deliver student assessment scores, which when correlated to external measure of standardized American Chemical Society (ACS) examinations and class score show a significant relationship between the accuracy of knowledge assessment (p=0.000). Use of eye-tracking technology and student interviews supports the measurements found in the classroom.

  15. Music expertise shapes audiovisual temporal integration windows for speech, sinewave speech and music

    Directory of Open Access Journals (Sweden)

    Hwee Ling eLee

    2014-08-01

    Full Text Available This psychophysics study used musicians as a model to investigate whether musical expertise shapes the temporal integration window for audiovisual speech, sinewave speech or music. Musicians and non-musicians judged the audiovisual synchrony of speech, sinewave analogues of speech, and music stimuli at 13 audiovisual stimulus onset asynchronies (±360, ±300 ±240, ±180, ±120, ±60, and 0 ms. Further, we manipulated the duration of the stimuli by presenting sentences/melodies or syllables/tones. Critically, musicians relative to non-musicians exhibited significantly narrower temporal integration windows for both music and sinewave speech. Further, the temporal integration window for music decreased with the amount of music practice, but not with age of acquisition. In other words, the more musicians practiced piano in the past three years, the more sensitive they became to the temporal misalignment of visual and auditory signals. Collectively, our findings demonstrate that music practicing fine-tunes the audiovisual temporal integration window to various extents depending on the stimulus class. While the effect of piano practicing was most pronounced for music, it also generalized to other stimulus classes such as sinewave speech and to a marginally significant degree to natural speech.

  16. Exchanging expertise and constructing boundaries: The development of a transnational knowledge network around heroin-assisted treatment.

    Science.gov (United States)

    Duke, Karen

    2016-05-01

    Over the last 20 years, supervised injectable and inhalable heroin prescribing has been developed, tested and in some cases introduced as a second line treatment for limited groups of entrenched heroin users in a number of European countries and Canada. Based on documentary analyses and eleven key informant interviews, this paper investigates the growth of 'expertise' and the sharing of knowledge between scientific stakeholders from different countries involved in researching and developing this area of treatment. Drawing on Stone's concept of the 'knowledge network' (Stone, 2013) and Gieryn's theory of 'boundary-work' (Gieryn, 1983), the analysis demonstrates the collective power of this group of scientists in producing a particular form of knowledge and expertise which has accrued and been exchanged over time. It also illustrates the ways in which this type of science has gained credibility and authority and become legitimised, reinforced and reproduced by those who employ it in both scientific and political debates. Boundaries were constructed by the knowledge network between different types of professions/disciplines, different forms of science and between the production of science and its consumption by non-scientists. The uniformity of the knowledge network in terms of their professional and disciplinary backgrounds, methodological expertise and ideological perspectives has meant that alternative forms of knowledge and perspectives have been neglected. This limits the nature and scope of the scientific evidence on which to base policy and practice decisions impacting on the work of policy makers and practitioners as well as the experiences of those in treatment who are most affected by this research and policy development.

  17. Clinical Ethics Consultants are not “Ethics” Experts—But They do Have Expertise 1

    Science.gov (United States)

    Rasmussen, Lisa M.

    2016-01-01

    The attempt to critique the profession of clinical ethics consultation by establishing the impossibility of ethics expertise has been a red herring. Decisions made in clinical ethics cases are almost never based purely on moral judgments. Instead, they are all-things-considered judgments that involve determining how to balance other values as well. A standard of justified decision-making in this context would enable us to identify experts who could achieve these standards more often than others, and thus provide a basis for expertise in clinical ethics consultation. This expertise relies in part on what Richard Zaner calls the “expert knowledge of ethical phenomena” (1988, 8). PMID:27302970

    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

    Under a conventional two-arm randomised trial design, participants are allocated to an intervention and participating health professionals are expected to deliver both interventions. However, health professionals often have differing levels of expertise in a skill-based interventions such as surgery or psychotherapy. An expertise-based approach to trial design, where health professionals only deliver an intervention in which they have expertise, has been proposed as an alternative. The aim of this project was to systematically review the use of an expertise-based trial design in the medical literature. We carried out a comprehensive search of nine databases--AMED, BIOSIS, CENTRAL, CINAHL, Cochrane Methodology Register, EMBASE, MEDLINE, Science Citation Index, and PsycINFO--from 1966 to 2012 and performed citation searches using the ISI Citation Indexes and Scopus. Studies that used an expertise-based trial design were included. Two review authors independently screened the titles and abstracts and assessed full-text reports. Data were extracted and summarised on the study characteristics, general and expertise-specific study methodology, and conduct. In total, 7476 titles and abstracts were identified, leading to 43 included studies (54 articles). The vast majority (88%) used a pure expertise-based design; three (7%) adopted a hybrid design, and two (5%) used a design that was unclear. Most studies compared substantially different interventions (79%). In many cases, key information relating to the expertise-based design was absent; only 12 (28%) reported criteria for delivering both interventions. Most studies recruited the target sample size or very close to it (median of 101, interquartile range of 94 to 118), although the target was reported for only 40% of studies. The proportion of participants who received the allocated intervention was high (92%, interquartile range of 82 to 99%). While use of an expertise-based trial design is growing, it remains uncommon

To address this gap, the researchers interviewed 16 international experts in female pelvic medicine and reconstructive surgery to assess their reflective perceptions of what specific opportunities and experiences initiated and supported their development toward expertise in their field. Characteristics and influences explaining the speed and quality of expertise development were sorted into the following themes: the dynamic process of expertise development, internal and personal characteristics, general aptitudes and preparatory skills, role modeling and interpersonal influences, opportunities to learn and practice, and roles and reference points. Across the narratives and perspectives of these expert surgeons, both individual characteristics and choices, and contextual activities and opportunities were necessary and important. Experiences with greatest impact on quality of expertise development included those provided by the environment and mentors, as well as those sought out by learners themselves, to elaborate and supplement existing opportunities. The ideal combination across experts was interaction and integration of individual characteristics with experiential opportunities. Grounded in theory and research in expertise development, these findings can support improvement of medical education, both for individual mentors and strategic program development.

    Hospital inpatient stays are reimbursed on the basis of German diagnosis-related groups (G-DRG). The G-DRG classification system is based on complex coding guidelines. The Medical Review Board of the Statutory Health Insurance Funds (MDK) examines the encoding by hospitals and delivers individual expertises on behalf of the German statutory health insurance companies in cases in which irregularities are suspected. A study was conducted on the inter-rater reliability of the MDK expertises regarding the scope of the assessment. A representative sample of 212 MDK expertises was taken from a selected pool of 1 392 MDK expertises in May 2013. This representative sample underwent a double-examination by 2 independent MDK experts using a special software based on the 3MTM G-DRG Grouper 2013 of 3M Medica, Germany. The following items encoded by the hospitals were examined: DRG, principal diagnosis, secondary diagnoses, procedures and additional payments. It was analysed whether the results of MDK expertises were consistent, reliable and correct. 202 expertises were eligible for evaluation, containing a total of 254 questions regarding one or more of the 5 items encoded by hospitals. The double-examination by 2 independent MDK experts showed matching results in 187 questions (73.6%) meaning they had been examined consistently and correctly. 59 questions (23.2%) did not show matching results, nevertheless they had been examined correctly regarding the scope of the assessment. None of the principal diagnoses was significantly affected by inconsistent or wrong judgment. A representative sample of MDK expertises examining the DRG encoding by hospitals showed a very high percentage of correct examination by the MDK experts. Identical MDK expertises cannot be achieved in all cases due to the scope of the assessment. Further improvement and simplification of codes and coding guidelines are required to reduce the scope of assessment with regard to correct DRG encoding and its

    We describe in this paper a new approach for the management of scientific projects. This approach is the result of a long reflexion carried out within the MQDP (Methodology and Quality in the Project Development) group of INSU-CNRS, and continued with Guy Serra. Our reflexion was initiated with the study of the so-called `North-American Paradigm' which was, initially considered as the only relevant management model. Through our active participation in several astrophysical projects we realized that this model could not be applied to our laboratories without major modifications. Therefore, step-by-step, we have constructed our own methodology, using to the fullest human potential resources existing in our research field, their habits and skills. We have also participated in various working groups in industrial and scientific organisms for the benefits of CNRS. The management model presented here is based on a systemic and complex approach. This approach lets us describe the multiple aspects of a scientific project specially taking into account the human dimension. The project system model includes three major interconnected systems, immersed within an influencing and influenced environment: the `System to be Realized' which defines scientific and technical tasks leading to the scientific goals, the `Realizing System' which describes procedures, processes and organization, and the `Actors' System' which implements and boosts all the processes. Each one exists only through a series of successive models, elaborated at predefined dates of the project called `key-points'. These systems evolve with time and under often-unpredictable circumstances and the models have to take it into account. At these key-points, each model is compared to reality and the difference between the predicted and realized tasks is evaluated in order to define the data for the next model. This model can be applied to any kind of projects.

    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.

    Full Text Available Background/Aims: The influence of the endoscopist on the polyp detection rate (PDR is underappreciated in clinical practice. Moreover, flat lesions or lesions of the proximal colon are more difficult to detect. Here, we evaluated the differences in the PDR and the characteristics of detected polyps according to the experience of the colonoscopist. Methods: We collected data on 2,549 patients who underwent screening colonoscopy performed by three fellows. The PDR was calculated according to the percentage of patients who had at least one polyp (method A and according to the percentage of detected lesions (method B. The primary outcome included the change in the PDR, and the secondary outcome included the change in the characteristics of the detected polyps with increasing experience of the colonoscopist. Results: No proportional correlation was found between the PDR and increasing experience in colonoscopy with method A; however, with method B, the PDR increased after 400 colonoscopies (p=0.0209. With method B, the detection rates of small polyps (<5 mm (p=0.0015 and polyps in proximal sites (p=0.0050 increased after 300 colonoscopies. Conclusions: Our study demonstrated that the quality of a colonoscopy, measured by using the PDR, may increase when performed by experienced fellows.

    Many studies have previously focused on how people with different levels of expertise solve physics problems. In early work, focus was on characterising differences between experts and novices and a key finding was the central role that propositionally expressed principles and laws play in expert, but not novice, problem-solving. A more recent line of research has focused on characterising continuity between experts and novices at the level of non-propositional knowledge structures and processes such as image-schemas, imagistic simulation and analogical reasoning. This study contributes to an emerging literature addressing the coordination of both propositional and non-propositional knowledge structures and processes in the development of expertise. Specifically, in this paper, we compare problem-solving across two levels of expertise-undergraduate students of chemistry and Ph.D. students in physical chemistry-identifying differences in how conceptual metaphors (CMs) are used (or not) to coordinate propositional and non-propositional knowledge structures in the context of solving problems on entropy. It is hypothesised that the acquisition of expertise involves learning to coordinate the use of CMs to interpret propositional (linguistic and mathematical) knowledge and apply it to specific problem situations. Moreover, we suggest that with increasing expertise, the use of CMs involves a greater degree of subjective engagement with physical entities and processes. Implications for research on learning and instructional practice are discussed. Third contribution to special issue entitled: Conceptual metaphor and embodied cognition in science learning

    Full Text Available 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 towards 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 towards a comprehensive approach to the route to expertise.

  13. 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.

    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.

    2011-01-01

    One of the most influential studies in all expertise research is de Groot's (1946) study of chess players, which suggested that pattern recognition, rather than search, was the key determinant of expertise. Many changes have occurred in the chess world since de Groot's study, leading some authors to argue that the cognitive mechanisms underlying expertise have also changed. We decided to replicate de Groot's study to empirically test these claims and to examine whether the trends in the data have changed over time. Six Grandmasters, five International Masters, six Experts, and five Class A players completed the think-aloud procedure for two chess positions. Findings indicate that Grandmasters and International Masters search more quickly than Experts and Class A players, and that both groups today search substantially faster than players in previous studies. The findings, however, support de Groot's overall conclusions and are consistent with predictions made by pattern recognition models. Copyright © 2011 Cognitive Science Society, Inc.

    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.

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

    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.

    2005-06-01

    The number of researchers studying perceptual-cognitive expertise in sport is increasing. The intention in this paper is to review the currently accepted framework for studying expert performance and to consider implications for undertaking research work in the area of perceptual-cognitive expertise in sport. The expert performance approach presents a descriptive and inductive approach for the systematic study of expert performance. The nature of expert performance is initially captured in the laboratory using representative tasks that identify reliably superior performance. Process-tracing measures are employed to determine the mechanisms that mediate expert performance on the task. Finally, the specific types of activities that lead to the acquisition and development of these mediating mechanisms are identified. General principles and mechanisms may be discovered and then validated by more traditional experimental designs. The relevance of this approach to the study of perceptual-cognitive expertise in sport is discussed and suggestions for future work highlighted.

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.

    Geoscience faculty members often debate about the definition and development of scientific expertise. Some will argue it emerges at the graduate level, others that novice students can develop relevant skills. The debate hinges on definitions of “expertise”, “scientific skills” and how these abilities are assessed. We present data from a second year geoscience course specifically designed to help research scientists foster generic skills associated with critical scientific thinking, presentation, and framing of scientific arguments and questions. To develop the course, key characteristics that professional scientists exhibit were identified from the literature and our experience. These are the abilities to: a) read critically; b) succinctly summarize and communicate; c) pose insightful questions; d) use and discuss models, data and their relationships; and e) work effectively as part of a team. To help with learning and assessment of these skills in students who do not yet have significant discipline-specific background, classroom practices were chosen so that students must think and act more like professional scientists. These include use of some team-based learning strategies, replacing exams with quizzes and projects, mixing team-teaching with solo-teaching, discursive rather than didactic instruction, and use of diverse topics representative of research in our Department. Specific strategies employed which enable “master geoscientists” to actively guide and assess novices as they practice desired skills are: homework involving reading, writing abstracts and posing questions for one or two articles each week, pre-post testing of model based reasoning abilities, interaction with guest scientists, and oral and poster presentations on topics chosen by students. Results of collecting data over two terms of using these general and specific strategies include: 1. Abstract writing skills improved during the first two thirds of the course, then leveled off in

    Background: This exploratory study is part of a larger-scale research project aimed at building theoretical and practical knowledge of complex systems in students and teachers with the goal of improving high school biology learning through professional development and a classroom intervention. Purpose: We propose a model of adaptive expertise to better understand teachers' classroom practices as they attempt to navigate myriad variables in the implementation of biology units that include working with computer simulations, and learning about and teaching through complex systems ideas. Sample: Research participants were three high school biology teachers, two females and one male, ranging in teaching experience from six to 16 years. Their teaching contexts also ranged in student achievement from 14-47% advanced science proficiency. Design and methods: We used a holistic multiple case study methodology and collected data during the 2011-2012 school year. Data sources include classroom observations, teacher and student surveys, and interviews. Data analyses and trustworthiness measures were conducted through qualitative mining of data sources and triangulation of findings. Results: We illustrate the characteristics of adaptive expertise of more or less successful teaching and learning when implementing complex systems curricula. We also demonstrate differences between case study teachers in terms of particular variables associated with adaptive expertise. Conclusions: This research contributes to scholarship on practices and professional development needed to better support teachers to teach through a complex systems pedagogical and curricular approach.

    Full Text Available Perceptual expertise is notoriously specific and bound by familiarity; generalizing to novel or unfamiliar images, objects, identities, and categories often comes at some cost to performance. In forensic and security settings, however, examiners are faced with the task of discriminating unfamiliar images of unfamiliar objects within their general domain of expertise (e.g., fingerprints, faces, or firearms. The job of a fingerprint expert, for instance, is to decide whether two unfamiliar fingerprint images were left by the same unfamiliar finger (e.g., Smith's left thumb, or two different unfamiliar fingers (e.g., Smith and Jones's left thumb. Little is known about the limits of this kind of perceptual expertise. Here, we examine fingerprint experts' and novices' ability to distinguish fingerprints compared to inverted faces in two different tasks. Inverted face images serve as an ideal comparison because they vary naturally between and within identities, as do fingerprints, and people tend to be less accurate or more novice-like at distinguishing faces when they are presented in an inverted or unfamiliar orientation. In Experiment 1, fingerprint experts outperformed novices in locating categorical fingerprint outliers (i.e., a loop pattern in an array of whorls, but not inverted face outliers (i.e., an inverted male face in an array of inverted female faces. In Experiment 2, fingerprint experts were more accurate than novices at discriminating matching and mismatching fingerprints that were presented very briefly, but not so for inverted faces. Our data show that perceptual expertise with fingerprints can be flexible to changing task demands, but there can also be abrupt limits: fingerprint expertise did not generalize to an unfamiliar class of stimuli. We interpret these findings as evidence that perceptual expertise with unfamiliar objects is highly constrained by one's experience.

    This article explores and discusses the ongoing attempt to reinstate an ethos of neutrality in public administration. It focuses on the political benefits and costs of contemporary strategies in public administration for using expertise based on an ethos of neutrality. On the one hand, expertise...... may serve to allow a particular form of value neutrality that curbs abuse of political office, questions received wisdom on the efficacy of policy interventions, and thereby holds the potential to minimize the waste of public resources employed to meet political goals. On the other hand, the use...

    Pour certains, les langues sont des outils neutres sans liens (qu'ils soient nécessaires ou accidentels et historiques) avec des univers culturels, sans liens avec des façons de penser. Pour ceux-là, en tout cas, elles peuvent n'être que des outils quand on tient des discours scientifiques, ce qui implique une conception de la science comme étant neutre, objective, détachée du monde social. Dans cette vision, on peut sans encombre, y compris en sciences humaines, choisir n'importe quelle(s) langue(s) pour le faire. L'objectif de ce volume est de proposer une autre vision des rapports profonds

  13. BOOK REVIEW: The Expertise and Deployment of Science Teachers at Key Stage 4

    Science.gov (United States)

    Dobson, Ken

    2000-03-01

    On my bookshelves I have a large collection of the issues of a prestigious research journal dealing with science education. From time to time I dip into the articles in search of enlightenment, applicable ideas or sheer entertainment. It is rare to find success in any of the categories, but I do learn a lot of new words. Or at least how to spell them. It makes me wonder who it is that reads educational research, except other educational researchers. It would be an interesting research project to find out what, if any, practical changes in teaching, learning or the organization of educational establishments resulted from the regular annual supply of research. I would guess that very few practising teachers have access to such learned journals, let alone the time to read them. Another possible readership, Science Advisers, are, as a species, verging on extinction. Of course, `knowledge for its own sake' is not to be despised, but I would rate usable, effective, practicable and knowledge rather higher. Having thus sufficiently annoyed a significant minority of the readership of Physics Education to make them take an interest, I shall go on to review the booklet produced by Donnelly and Jenkins. These two have had the temerity to `explore, in a preliminary way' the topic given in the title. Further, they have dared to expose their work to the common gaze in a short, readable and easily accessible booklet. You might be led to believe from this that they have a strong desire that what they say should have an effect on what really happens in the (south) British educational system. They deal with a topic that anyone with an interest in, and especially with responsibility for, curriculum and its development, in-service education and training and the supply of science teachers should be strongly concerned (i.e. worried) about. Who teaches science? How are they qualified to do so? Are the teachers happy with the match between their qualifications and their teaching roles? And

    2011-03-01

    Pneumoconiosis, a lung disease caused by the inhalation of dust, is mainly diagnosed using chest radiographs. The effects of using contralateral symmetric (CS) information present in chest radiographs in the diagnosis of pneumoconiosis are studied using an eye tracking experimental study. The role of expertise and the influence of CS information on the performance of readers with different expertise level are also of interest. Experimental subjects ranging from novices & medical students to staff radiologists were presented with 17 double and 16 single lung images, and were asked to give profusion ratings for each lung zone. Eye movements and the time for their diagnosis were also recorded. Kruskal-Wallis test (χ2(6) = 13.38, p = .038), showed that the observer error (average sum of absolute differences) in double lung images differed significantly across the different expertise categories when considering all the participants. Wilcoxon-signed rank test indicated that the observer error was significantly higher for single-lung images (Z = 3.13, p error between single and double lung images is significantly higher in doctors [staff & residents] than in non-doctors [others]. Thus, Expertise & CS information plays a significant role in the diagnosis of pneumoconiosis. CS information helps in diagnosing pneumoconiosis by reducing the general tendency of giving less profusion ratings. Training and experience appear to play important roles in learning to use the CS information present in the chest radiographs.

  7. Musical Expertise Increases Top–Down Modulation Over Hippocampal Activation during Familiarity Decisions

    Directory of Open Access Journals (Sweden)

    Pierre Gagnepain

    2017-09-01

    Full Text Available The hippocampus has classically been associated with episodic memory, but is sometimes also recruited during semantic memory tasks, especially for the skilled exploration of familiar information. Cognitive control mechanisms guiding semantic memory search may benefit from the set of cognitive processes at stake during musical training. Here, we examined using functional magnetic resonance imaging, whether musical expertise would promote the top–down control of the left inferior frontal gyrus (LIFG over the generation of hippocampally based goal-directed thoughts mediating the familiarity judgment of proverbs and musical items. Analyses of behavioral data confirmed that musical experts more efficiently access familiar melodies than non-musicians although such increased ability did not transfer to verbal semantic memory. At the brain level, musical expertise specifically enhanced the recruitment of the hippocampus during semantic access to melodies, but not proverbs. Additionally, hippocampal activation contributed to speed of access to familiar melodies, but only in musicians. Critically, causal modeling of neural dynamics between LIFG and the hippocampus further showed that top–down excitatory regulation over the hippocampus during familiarity decision specifically increases with musical expertise – an effect that generalized across melodies and proverbs. At the local level, our data show that musical expertise modulates the online recruitment of hippocampal response to serve semantic memory retrieval of familiar melodies. The reconfiguration of memory network dynamics following musical training could constitute a promising framework to understand its ability to preserve brain functions.

    International Nuclear Information System (INIS)

    Henkels, M.

    1989-01-01

    The role of agency expertise in the nuclear waste policy process is explored during three periods: (1) 1957-1959 when nuclear wastes entered the public agenda, (2) 1970-1972 when the Atomic Energy Commission attempted to establish a waste repository in Kansas, and (3) 1984-1986 during the Department of Energy's implementation of the Nuclear Waste Policy Act of 1982. The study evaluated whether the preconditions for dependence on or deference to agency expertise have become less favorable, weakening agency control of the policy process. Five factors of expertise power are evaluated, beginning with the agency's role in the nuclear-energy and radioactive-waste information system. Perspectives on nuclear energy generally and of waste issues specifically are examined next; both indicate attitudes on the tractability of the problem and the likelihood of policy success. References to agency behavior and policies are used to evaluate views of agency competency. Finally, views of agency trustworthiness are examined through the comparison of portrayals of agency priorities and motivations. Agency expertise is evaluated in four contexts: (1) Congressional hearings, (2) nationally prominent newspapers, (3) journals of the scientific community, and (4) state and local papers of affected areas. State and tribal officials involved in the 1980s' nuclear waste policy process were surveyed also

  5. What does physicians' clinical expertise contribute to oncologic decision-making? A qualitative interview study.

    Science.gov (United States)

    Salloch, Sabine; Otte, Ina; Reinacher-Schick, Anke; Vollmann, Jochen

    2018-02-01

    Physicians' clinical expertise forms an exclusive body of competences, which helps them to find the appropriate diagnostics and treatment for each individual patient. Empirical evidence, however, suggests that there is an inverse relationship between the number of years in practice and the quality of care provided by a physician. Knowledge and adherence to professional standards (such as clinical guidelines) are often used as indicators in previous research. Semistructured interviews and the Q method were used for an explorative study on oncologists' views on the interplay between their own clinical expertise, intuition, and the external evidence incorporated in clinical guidelines. The interviews were audio recorded, transcribed ad verbatim, and analysed using qualitative content analysis. Data analysis shows the complex character of clinical expertise with respect to experience, professional development, and intuition. An irreplaceable role is attributed to personal and bodily experience during the providing of care for a patient. Professional experience becomes important, particularly in those situations that lie out of the focus of "guideline medicine." Intuition is regarded as having a strong emotional component and helps for deciding which therapeutic option the patient can deal with. Using measurable knowledge and adherence to standards as indicators does not account for the complexity of clinical expertise. Other factors, such as the importance of bodily experience and physicians' intuitive knowledge, must be considered, also with respect to the occurrence of treatment biases. © 2017 John Wiley & Sons, Ltd.

    Skoyles's case against human brain size being related to IQ is strong; but his case in favor of its being related to expertise is weak. I propose that the explanation for the evolutionary expansion of the human brain in fact lies far away, in the need to have a brain that could continue to function into old age.

  17. Bureaucratic power in note-writing: authoritative expertise within the state.

    Science.gov (United States)

    Mangset, Marte; Asdal, Kristin

    2018-02-24

    What produces the power of senior civil servants at ministries of finance, positioned at the top of the bureaucratic hierarchy? Max Weber has claimed that a hierarchical organization, meritocratic recruitment and procedural work provide bureaucracies with legitimacy. In particular he insisted on the role of Fachwissen (disciplinary knowledge) obtained through formal education. However, he also argued for the role of Dienstwissen, forms of knowledge and skills stemming from the experience of service in itself. Weber did not elaborate on this concept in detail, and few analysts of governmental expertise have examined this notion. We draw on the practice-turn in sociology, combining the study of governmental expertise with micro-sociological studies of administrative practices. By analysing interviews with 48 senior civil servants at the British, French and Norwegian ministries of finance about their daily practices, this article demonstrates that bureaucratic note-writing and the procedural evaluation of such notes constitute a key form of expertise that yields authority. The study provides an analytical framework for understanding what administrative expertise consists of, how it is integral to procedural work, the forms bureaucratic hierarchies take in practice and how these three dimensions provide authority. © London School of Economics and Political Science 2018.

    2017-01-01

    How does the human visual system accommodate expertise for two simultaneously acquired symbolic systems? We used fMRI to compare activations induced in the visual cortex by musical notation, written words and other classes of objects, in professional musicians and in musically naïve controls. First, irrespective of expertise, selective activations for music were posterior and lateral to activations for words in the left occipitotemporal cortex. This indicates that symbols characterized by different visual features engage distinct cortical areas. Second, musical expertise increased the volume of activations for music and led to an anterolateral displacement of word-related activations. In musicians, there was also a dramatic increase of the brain-scale networks connected to the music-selective visual areas. Those findings reveal that acquiring a double visual expertise involves an expansion of category-selective areas, the development of novel long-distance functional connectivity, and possibly some competition between categories for the colonization of cortical space.

  4. Effects of musical expertise on oscillatory brain activity in response to emotional sounds.

    Nolden, Sophie; Rigoulot, Simon; Jolicoeur, Pierre; Armony, Jorge L

    2017-08-01

    Emotions can be conveyed through a variety of channels in the auditory domain, be it via music, non-linguistic vocalizations, or speech prosody. Moreover, recent studies suggest that expertise in one sound category can impact the processing of emotional sounds in other sound categories as they found that musicians process more efficiently emotional musical and vocal sounds than non-musicians. However, the neural correlates of these modulations, especially their time course, are not very well understood. Consequently, we focused here on how the neural processing of emotional information varies as a function of sound category and expertise of participants. Electroencephalogram (EEG) of 20 non-musicians and 17 musicians was recorded while they listened to vocal (speech and vocalizations) and musical sounds. The amplitude of EEG-oscillatory activity in the theta, alpha, beta, and gamma band was quantified and Independent Component Analysis (ICA) was used to identify underlying components of brain activity in each band. Category differences were found in theta and alpha bands, due to larger responses to music and speech than to vocalizations, and in posterior beta, mainly due to differential processing of speech. In addition, we observed greater activation in frontal theta and alpha for musicians than for non-musicians, as well as an interaction between expertise and emotional content of sounds in frontal alpha. The results reflect musicians' expertise in recognition of emotion-conveying music, which seems to also generalize to emotional expressions conveyed by the human voice, in line with previous accounts of effects of expertise on musical and vocal sounds processing.

  5. Expertise Effects in Face-Selective Areas are Robust to Clutter and Diverted Attention, but not to Competition.

    2015-09-01

    Expertise effects for nonface objects in face-selective brain areas may reflect stable aspects of neuronal selectivity that determine how observers perceive objects. However, bottom-up (e.g., clutter from irrelevant objects) and top-down manipulations (e.g., attentional selection) can influence activity, affecting the link between category selectivity and individual performance. We test the prediction that individual differences expressed as neural expertise effects for cars in face-selective areas are sufficiently stable to survive clutter and manipulations of attention. Additionally, behavioral work and work using event related potentials suggest that expertise effects may not survive competition; we investigate this using functional magnetic resonance imaging. Subjects varying in expertise with cars made 1-back decisions about cars, faces, and objects in displays containing one or 2 objects, with only one category attended. Univariate analyses suggest car expertise effects are robust to clutter, dampened by reducing attention to cars, but nonetheless more robust to manipulations of attention than competition. While univariate expertise effects are severely abolished by competition between cars and faces, multivariate analyses reveal new information related to car expertise. These results demonstrate that signals in face-selective areas predict expertise effects for nonface objects in a variety of conditions, although individual differences may be expressed in different dependent measures depending on task and instructions. © The Author 2014.

    The life management of French Nuclear Power Plants is a major stake from an economic and a technical point of view considering the aging management assessment of the key components of the plant. The actual life evaluation is the result of prediction of life assessment from important program of expertise for the 3-loop PWR and 4-loop PWR plants in operation. To optimize the strategic policy in order to achieve the best possible performance and to prepare the technical and economical choice and decision, the paper presents the association of life management strategy and the program of expertise considering: - the identification of degradation for different components and prediction criteria proposed; - the large database from cast reactor coolant and component removed from nuclear power plants and expertise studies to confirm the prediction; - the life evaluation of RPV with radiation surveillance program based on the expertise of irradiation capsules, it is particularly shown how the expertise is in the center of the strategic choice. The French utility has organized the life management of nuclear plant as a function of several programs of expertise of knowledge on the long term experience feedback and the maintenance program for life. This paper shows updated on RPV and reactor coolant equipment activities engaged by utility on: - periodic maintenance and volume of expertise; - Alternative maintenance actions; - Large volume of expertise and how are managed these results to predict the aging management.

    Masson, M.; Malaise, N.; Housiaux, A.; Keyser, V. de

    1993-01-01

    Reliability and safety are two very important goals, which depend on technical and organizational factors, but also on human expertise. How to ensure a safe functioning of a nuclear power plant in a changing context, and what might be the role and aspects of training and transfer of knowledge? These are the questions we shall deal with in this paper, on the basis of two field studies. The two field studies stress the needs for setting up case based training, which best ensure the acquisition of know-how. Furthermore, as shown by the second one, gaining expertise involves developing large repertoires of highly skilled, semi-routinized activities. Supporting expert operators not only should tackle problem solving activities but should thus also include the prevention of routine errors, which go along with skill acquisition. (orig.)

    Science is critical to society’s ability to prepare for, respond to, and recover from environmental crises. Natural and technological disasters such as disease outbreaks, volcanic eruptions, hurricanes, oil spills, and tsunamis require coordinated scientific expertise across a range of disciplines to shape effective policies and protocols. Five years after the Deepwater Horizon oil spill, new organizational frameworks have arisen for scientists and engineers to apply their expertise to disaster response and recovery in a variety of capacities. Here, we describe examples of these opportunities, including an exciting new collaboration between the Association for the Sciences of Limnology and Oceanography (ASLO) and the Department of the Interior’s (DOI) Strategic Sciences Group (SSG).

    Full Text Available This study evaluated a model of student-engaged educational development. Despite widespread commitment to student engagement across many institutional activities, student participation as partners with faculty in teaching and learning enhancement has been identified as a threshold concept for educational development. This study sought not only to establish a student-engaged model of teaching observation in a United Kingdom context, but also to critically examine the ways in which student, faculty, and developer participants conceptualise student expertise in relation to learning and teaching. Concept-map mediated interviews with students and faculty in humanities and healthcare subjects elicited conceptions and comparative knowledge structures of pedagogical intelligence for the purposes of enhancing teaching practice. The outcomes of the study are considered in relation to the theorisation of student engagement with particular focus on perspectives of expertise and power relations.

  15. Exploring factors related to college student expertise in digital games and their relationships to academics

    Directory of Open Access Journals (Sweden)

    Hamlen Karla R.

    2017-06-01

    Full Text Available Digital game play is a common pastime among college students and monopolizes a great deal of time for many students. Researchers have previously investigated relationships between subject-specific game play and academics, but this study fulfills a need for research focusing on entertainment game strategies and how they relate to strategies and success in other contexts. Utilizing a survey of 191 undergraduate students, the goal was to investigate students’ digital game play habits, strategies, and beliefs that predict gaming expertise, and to determine if these relate to academic success. Factor analysis revealed three latent variables that predict expertise: dedication, solo mastery, and strategic play. Multiple regression analysis was used to determine whether these three components could also predict academic outcome variables. Findings point to the absence of a relationship between these variables and academic GPA, but to the presence of a tentative relationship between confidence in game play and confidence in personal control over academic success.

  18. Metacognition and action: A new pathway to understanding social and cognitive aspects of expertise in sport

    Directory of Open Access Journals (Sweden)

    Tadhg Eoghan Macintyre

    2014-10-01

    Full Text Available For over a century, psychologists have investigated the mental processes of expert performers - people who display exceptional knowledge and/or skills in specific fields of human achievement. Since the 1960s, expertise researchers have made considerable progress in understanding the cognitive and neural mechanisms that underlie such exceptional performance. Whereas the first modern studies of expertise were conducted in relatively formal knowledge domains such as chess, more recent investigations have explored elite performance in dynamic perceptual-motor activities such as sport. Unfortunately, although these studies have led to the identification of certain domain-free generalizations about expert-novice differences, they shed little light on an important issue: namely, experts’ metacognitive activities or their insights into, and regulation of, their own mental processes. In an effort to rectify this oversight, the present paper argues that metacognitive processes and inferences play an important if neglected role in expertise. In particular, we suggest that metacognition (including such processes as ‘meta-attention’, ‘meta-imagery’ and ‘meta-memory’, as well as social aspects of this construct provides a window on the genesis of expert performance. Following a critique of the standard empirical approach to expertise, we explore some research on ‘metacognition’ and ‘metacognitive inference’ among experts in sport. After that, we provide a brief evaluation of the relationship between psychological skills training and metacognition and comment on the measurement of metacognitive processes. Finally, we summarize our conclusions and outline some potentially new directions for research on metacognition in action.

  20. The Inverse Relation Between Risks and Benefits: The Role of Affect and Expertise.

    Science.gov (United States)

    Sokolowska, Joanna; Sleboda, Patrycja

    2015-07-01

    Although risk and benefits of risky activities are positively correlated in the real world, empirical results indicate that people perceive them as negatively correlated. The common explanation is that confounding benefits and losses stems from affect. In this article, we address the issue that has not been clearly established in studies on the affect heuristic: to what extent boundary conditions, such as judgments' generality and expertise, influence the presence of the inverse relation in judgments of hazards. These conditions were examined in four studies in which respondents evaluated general or specific benefits and risks of "affect-rich" and "affect-poor" hazards (ranging from investments to applications of stem cell research). In line with previous research, affect is defined as good or bad feelings integral to a stimulus. In contrast to previous research, affect is considered as related both to personal feelings and to social controversies associated with a hazard. Expertise is related to personal knowledge (laypersons vs. experts) as well as to objective knowledge (targets well vs. poorly known to science). The direct comparison of the input from personal and objective ignorance into the inverse relation has not been investigated previously. It was found that affect invoked by a hazard guides general but not specific judgments of its benefits and risks. Technical expertise helps to avoid simplified evaluations of consequences as long as they are well known to science. For new, poorly understood hazards (e.g., stem cell research), expertise does not protect from the perception of the inverse relation between benefits and risks. © 2015 Society for Risk Analysis.

  1. Dynamical signatures of isometric force control as a function of age, expertise, and task constraints.

    From the conceptual and methodological framework of the dynamical systems approach, force control results from complex interactions of various subsystems yielding observable behavioral fluctuations, which comprise both deterministic (predictable) and stochastic (noise-like) dynamical components. Here, we investigated these components contributing to the observed variability in force control in groups of participants differing in age and expertise level. To this aim, young (18-25 yr) as well as late middle-aged (55-65 yr) novices and experts (precision mechanics) performed a force maintenance and a force modulation task. Results showed that whereas the amplitude of force variability did not differ across groups in the maintenance tasks, in the modulation task it was higher for late middle-aged novices than for experts and higher for both these groups than for young participants. Within both tasks and for all groups, stochastic fluctuations were lowest where the deterministic influence was smallest. However, although all groups showed similar dynamics underlying force control in the maintenance task, a group effect was found for deterministic and stochastic fluctuations in the modulation task. The latter findings imply that both components were involved in the observed group differences in the variability of force fluctuations in the modulation task. These findings suggest that between groups the general characteristics of the dynamics do not differ in either task and that force control is more affected by age than by expertise. However, expertise seems to counteract some of the age effects. NEW & NOTEWORTHY Stochastic and deterministic dynamical components contribute to force production. Dynamical signatures differ between force maintenance and cyclic force modulation tasks but hardly between age and expertise groups. Differences in both stochastic and deterministic components are associated with group differences in behavioral variability, and observed behavioral

    Clinical reasoning is dependent upon working memory (WM). More precisely, during the clinical reasoning process stored information within long-term memory is brought into WM to facilitate the internal deliberation that affords a clinician the ability to reason through a case. In the present study, we examined the relationship between clinical reasoning and WM while participants read clinical cases with functional magnetic resonance imaging (fMRI). More specifically, we examined the impact of clinical case difficulty (easy, hard) and clinician level of expertise (2nd year medical students, senior gastroenterologists) on neural activity within regions of cortex associated with WM (i.e., the prefrontal cortex) during the reasoning process. fMRI was used to scan ten second-year medical students and ten practicing gastroenterologists while they reasoned through sixteen clinical cases [eight straight forward (easy) and eight complex (hard)] during a single 1-h scanning session. Within-group analyses contrasted the easy and hard cases which were then subsequently utilized for a between-group analysis to examine effects of expertise (novice > expert, expert > novice). Reading clinical cases evoked multiple neural activations in occipital, prefrontal, parietal, and temporal cortical regions in both groups. Importantly, increased activation in the prefrontal cortex in novices for both easy and hard clinical cases suggests novices utilize WM more so than experts during clinical reasoning. We found that clinician level of expertise elicited differential activation of regions of the human prefrontal cortex associated with WM during clinical reasoning. This suggests there is an important relationship between clinical reasoning and human WM. As such, we suggest future models of clinical reasoning take into account that the use of WM is not consistent throughout all clinical reasoning tasks, and that memory structure may be utilized differently based on level of expertise.

  11. Segmentation of dance movement: Effects of expertise, visual familiarity, motor experience and music

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available According to event segmentation theory, action perception depends on sensory cues and prior knowledge, and the segmentation of observed actions is crucial for understanding and memorizing these actions. While most activities in everyday life are characterized by external goals and interaction with objects or persons, this does not necessarily apply to dance-like actions. We investigated to what extent visual familiarity of the observed movement and accompanying music influence the segmentation of a dance phrase in dancers of different skill level and non-dancers. In Experiment 1, dancers and non-dancers repeatedly watched a video clip showing a dancer performing a choreographed dance phrase and indicated segment boundaries by key press. Dancers generally defined less segment boundaries than non-dancers, specifically in the first trials in which visual familiarity with the phrase was low. Music increased the number of segment boundaries in the non-dancers and decreased it in the dancers. The results suggest that dance expertise reduces the number of perceived segment boundaries in an observed dance phrase, and that the ways visual familiarity and music affect movement segmentation are modulated by dance expertise. In a second experiment, motor experience was added as factor, based on empirical evidence suggesting that action perception is modified by visual and motor expertise in different ways. In Experiment 2, the same task as in Experiment 1 was performed by dance amateurs, and was repeated by the same participants after they had learned to dance the presented dance phrase. Less segment boundaries were defined in the middle trials after participants had learned to dance the phrase, and music reduced the number of segment boundaries before learning. The results suggest that specific motor experience of the observed movement influences its perception and anticipation and makes segmentation broader, but not to the same degree as dance expertise

  12. Literally experts: expertise and the processing of analogical metaphors in pharmaceutical advertising.

    2014-01-01

    This research examined differences between novices and experts in processing analogical metaphors appearing in prescription drug advertisements. In contrast to previous studies on knowledge transfer, no evidence of the superiority of experts in processing metaphors was found. The results from an experiment suggest that expert consumers were more likely to process a metaphor in an ad literally than novices. Our findings point to a condition in which the expertise effect with processing analogies is not the linear relationship assumed in previous studies.

    In this study, we used high-density EEG to evaluate whether speech and music expertise has an influence on the categorization of expertise-related and unrelated sounds. With this purpose in mind, we compared the categorization of speech, music, and neutral sounds between professional musicians, simultaneous interpreters (SIs), and controls in response to morphed speech-noise, music-noise, and speech-music continua. Our hypothesis was that music and language expertise will strengthen the memory representations of prototypical sounds, which act as a perceptual magnet for morphed variants. This means that the prototype would "attract" variants. This so-called magnet effect should be manifested by an increased assignment of morphed items to the trained category, by a reduced maximal slope of the psychometric function, as well as by differential event-related brain responses reflecting memory comparison processes (i.e., N400 and P600 responses). As a main result, we provide first evidence for a domain-specific behavioral bias of musicians and SIs toward the trained categories, namely music and speech. In addition, SIs showed a bias toward musical items, indicating that interpreting training has a generic influence on the cognitive representation of spectrotemporal signals with similar acoustic properties to speech sounds. Notably, EEG measurements revealed clear distinct N400 and P600 responses to both prototypical and ambiguous items between the three groups at anterior, central, and posterior scalp sites. These differential N400 and P600 responses represent synchronous activity occurring across widely distributed brain networks, and indicate a dynamical recruitment of memory processes that vary as a function of training and expertise.

  15. Autistic expertise: a critical reflection on the production of knowledge in autism studies.

    Science.gov (United States)

    Milton, Damian Em

    2014-10-01

    The field of autism studies is a highly disputed territory within which competing contradictory discourses abound. In this field, it is the voices and claims of autistic people regarding their own expertise in knowledge production concerning autism that is most recent in the debate, and traditionally the least attended to. In this article, I utilise the theories of Harry Collins and colleagues in order to reflect upon and conceptualise the various claims to knowledge production and expertise within the field of autism studies, from the perspective of an author who has been diagnosed as being on the autism spectrum. The notion that autistic people lack sociality is problematised, with the suggestion that autistic people are not well described by notions such as the 'social brain', or as possessing 'zero degrees of cognitive empathy'. I then argue, however, that there is a qualitative difference in autistic sociality, and question to what extent such differences are of a biological or cultural nature, and to what extent interactional expertise can be gained by both parties in interactions between autistic and non-autistic people. In conclusion, I argue that autistic people have often become distrustful of researchers and their aims, and are frequently frozen out of the processes of knowledge production. Such a context results in a negative feedback spiral with further damage to the growth of interactional expertise between researchers and autistic people, and a breakdown in trust and communication leading to an increase in tension between stakeholder groups. The involvement of autistic scholars in research and improvements in participatory methods can thus be seen as a requirement, if social research in the field of autism is to claim ethical and epistemological integrity. © The Author(s) 2014.

  16. Cognitive-psychology expertise and the calculation of the probability of a wrongful conviction.

    Cognitive psychologists are familiar with how their expertise in understanding human perception, memory, and decision-making is applicable to the justice system. They may be less familiar with how their expertise in statistical decision-making and their comfort working in noisy real-world environments is just as applicable. Here we show how this expertise in ideal-observer models may be leveraged to calculate the probability of guilt of Gary Leiterman, a man convicted of murder on the basis of DNA evidence. We show by common probability theory that Leiterman is likely a victim of a tragic contamination event rather than a murderer. Making any calculation of the probability of guilt necessarily relies on subjective assumptions. The conclusion about Leiterman's innocence is not overly sensitive to the assumptions-the probability of innocence remains high for a wide range of reasonable assumptions. We note that cognitive psychologists may be well suited to make these calculations because as working scientists they may be comfortable with the role a reasonable degree of subjectivity plays in analysis.

  17. Many faces of expertise: fusiform face area in chess experts and novices.

    2011-07-13

    The fusiform face area (FFA) is involved in face perception to such an extent that some claim it is a brain module for faces exclusively. The other possibility is that FFA is modulated by experience in individuation in any visual domain, not only faces. Here we test this latter FFA expertise hypothesis using the game of chess as a domain of investigation. We exploited the characteristic of chess, which features multiple objects forming meaningful spatial relations. In three experiments, we show that FFA activity is related to stimulus properties and not to chess skill directly. In all chess and non-chess tasks, experts' FFA was more activated than that of novices' only when they dealt with naturalistic full-board chess positions. When common spatial relationships formed by chess objects in chess positions were randomly disturbed, FFA was again differentially active only in experts, regardless of the actual task. Our experiments show that FFA contributes to the holistic processing of domain-specific multipart stimuli in chess experts. This suggests that FFA may not only mediate human expertise in face recognition but, supporting the expertise hypothesis, may mediate the automatic holistic processing of any highly familiar multipart visual input.

    The Relative Age Effect (RAE) in sport has been targeted by many research studies. The objective of this study was to analyze, in amateur clubs, the RAE of soccer players, according to the sport expertise level of the team (e.g., A, B, C and subsequent) that they belong to within the same game category. 1,098 soccer players in formative stages took part in the study, with ages varying between 6 and 18 years old (U8 to U19 categories). All of them were members of 4 Spanish federated clubs. The birth dates were classified into 4 quartiles (Q1 = Jan-Mar; Q2 = Apr-Jun; Q3 = Jul-Sept; Q4 = Oct-Dec)according to the team they belonged to. The results obtained in the chi-squared test and d value (effect size) revealed the existence of RAE in the teams with the highest expertise level, "A" (X2 = 15.342, p = .002, d = 0.4473) and "B" (X2 = 10.905, p = .012, d = 0.3657). However, in the lower level teams, "C and subsequent", this effect was not observed. Present findings show that players born during the first months of the year tend to be selected to play in teams with a higher sport expertise level of each category, due to their physical maturity. Consequently, this causes differences in terms of the experience they accumulate and the motivation that this creates in these players.

  19. Expertise as evidence in criminal proceedings from the Communist period until nowadays

    Full Text Available During their procedural activity, investigative and judicial bodies have the pressing need to make use of special knowledge in different scientific fields of technique and science in order to resolve outstanding issues related to the subject of verification, which the law has defined as subject of expertise in criminal trial. Experts’ opinion is conceived and implemented as a particular means of verification; experts help in discovering the facts that are important to finding out the truth in criminal proceedings. In addition, they ascertain the facts and give an opinion on them, as a result of specific skills they have in the field of technique, science or culture. Experts and the process conducted by them were given importance in the legislation of the Communist era particularly with the drafting of the Code of Criminal Procedure of 1979 which provides in considerable detail both the functions and the importance of expertise to resolve a criminal case. Furthermore, nowadays expertise as evidence in criminal proceedings is becoming increasingly important and is emerging, especially in view of developments in the field of Technique and Science since many criminals are very good at using innovations as a priority means for escaping detection and punishment. But on the other hand, scientific developments are increasingly cooperating with law and justice institutions to resolve the events and to provide assistance for achieving quality results in a shorter time, something that probably was unthinkable before.

  20. Sonographic diagnostics of subcutaneous fibrosis and its significance in medical expertise of radiation damage

    In assessing radiation damage of the skin and of underlying tissue - particularly in judging the ability to work of persons with widespread subcutaneous fibrosis in the framework of expertises for invalidity - difficulties are occasionally encountered. One of the reasons for such difficulties is the observed intact state of upper layers of the skin, e.g. after exposure to gamma radiation in telecobalt therapy, which may conceal to the inexperienced doctor the tissue changes present in the deep layers. The experience gained by means of ultrasonic tomography with the purpose of reaching objective findings and determining the exact extent of fibrosis, is reported and examples of expertise are given and demonstrated by figures. The method is easy to handle and, provided by the doctor's expert knowledge, makes possible an exact assessment of the 3-dimensional extension of subcutaneous fibrosis of the squamous cell- and jacket-type, e.g. in the abdominal wall. Thus, sonographic measuring has proved to be a reliable means of expertise in cases of health damage after exposure to ionizing radiation which impairs the person's ability to work. (author)

    Focused attention enhances processing of some aspects of the world at the expense of unattended items. Although focused attention has been studied for decades, few studies have measured individual and group differences in how people distribute attention. In three studies, we explored differences in the breadth and distribution of attention as a function of athletic expertise. Study 1 found 25% greater attention breadth in expert athletes than in novices. Study 2 found that the distribution of focused attention for experts varied as a function of the type of athletic expertise: Experts in sports that demand greater horizontal distribution of attention (e.g., soccer) showed greater horizontal breadth of attention than did those whose sports demand more vertical attention (e.g., volleyball), and vice versa. Study 3 used a slightly modified design to replicate the results of Studies 1 and 2. Overall, the findings reveal a systematic association between the measured "shape" of focused attention in a laboratory task and expertise in a real-world skill.

  2. Eye movements as an index of pathologist visual expertise: a pilot study.

    Directory of Open Access Journals (Sweden)

    Tad T Brunyé

    Full Text Available A pilot study examined the extent to which eye movements occurring during interpretation of digitized breast biopsy whole slide images (WSI can distinguish novice interpreters from experts, informing assessments of competency progression during training and across the physician-learning continuum. A pathologist with fellowship training in breast pathology interpreted digital WSI of breast tissue and marked the region of highest diagnostic relevance (dROI. These same images were then evaluated using computer vision techniques to identify visually salient regions of interest (vROI without diagnostic relevance. A non-invasive eye tracking system recorded pathologists' (N = 7 visual behavior during image interpretation, and we measured differential viewing of vROIs versus dROIs according to their level of expertise. Pathologists with relatively low expertise in interpreting breast pathology were more likely to fixate on, and subsequently return to, diagnostically irrelevant vROIs relative to experts. Repeatedly fixating on the distracting vROI showed limited value in predicting diagnostic failure. These preliminary results suggest that eye movements occurring during digital slide interpretation can characterize expertise development by demonstrating differential attraction to diagnostically relevant versus visually distracting image regions. These results carry both theoretical implications and potential for monitoring and evaluating student progress and providing automated feedback and scanning guidance in educational settings.

  6. Experience does not equal expertise in recognizing infrequent incoming gunfire: neural markers for experience and task expertise at peak behavioral performance.

    Directory of Open Access Journals (Sweden)

    Jason Samuel Sherwin

    Full Text Available For a soldier, decisions to use force can happen rapidly and sometimes lead to undesired consequences. In many of these situations, there is a rapid assessment by the shooter that recognizes a threat and responds to it with return fire. But the neural processes underlying these rapid decisions are largely unknown, especially amongst those with extensive weapons experience and expertise. In this paper, we investigate differences in weapons experts and non-experts during an incoming gunfire detection task. Specifically, we analyzed the electroencephalography (EEG of eleven expert marksmen/soldiers and eleven non-experts while they listened to an audio scene consisting of a sequence of incoming and non-incoming gunfire events. Subjects were tasked with identifying each event as quickly as possible and committing their choice via a motor response. Contrary to our hypothesis, experts did not have significantly better behavioral performance or faster response time than novices. Rather, novices indicated trends of better behavioral performance than experts. These group differences were more dramatic in the EEG correlates of incoming gunfire detection. Using machine learning, we found condition-discriminating EEG activity among novices showing greater magnitude and covering longer periods than those found in experts. We also compared group-level source reconstruction on the maximum discriminating neural correlates and found that each group uses different neural structures to perform the task. From condition-discriminating EEG and source localization, we found that experts perceive more categorical overlap between incoming and non-incoming gunfire. Consequently, the experts did not perform as well behaviorally as the novices. We explain these unexpected group differences as a consequence of experience with gunfire not being equivalent to expertise in recognizing incoming gunfire.

    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

    Culture collections no matter their size, form, or institutional objectives play a role in underpinning microbiology, supplying the resources for study, innovation, and discovery. Their basic roles include providing a mechanism for ex situ conservation of organisms; they are repositories for strains subject to publication, taking in safe, confidential, and patent deposits from researchers. They supply strains for use; therefore, the microorganisms provided must be authentic and preserved well, and any associated information must be valid and sufficient to facilitate the confirmation of their identity and to facilitate their use. The organisms must be collected in compliance with international conventions, international and national legislation and distributed to users indicating clearly the terms and conditions under which they are received and can be used. Collections are harmonizing approaches and characterizing strains to meet user needs. No one single collection can carry out this task alone, and therefore, it is important that output and strategy are coordinated to ensure culture collections deliver the basic resources and services microbiological innovation requires.

  11. [Quality assurance in coding expertise of hospital cases in the German DRG system. Evaluation of inter-rater reliability in MDK expertise].

    2012-10-01

    The purpose of this study was to evaluate differences in the D-DRG results of a hospital case by 2 independently coding MKD raters. Calculation of the 2-inter-rater reliability was performed by examination of the coding of individual hospital cases. The reasons for the non-agreement of the expert evaluations and suggestions to improve the process are discussed. From the expert evaluation pool of the MDK-WL a random sample of 0.7% of the 57,375 expertises was taken. Distribution equality with the basic total was tested by the χ² test or, respectively, Fisher's exact test. For the total of 402 individual hospital cases, the G-DRG case sums of 2 experts of the MDK were determined independently and the results checked for each individual case for agreement or non-agreement. The corresponding confidence intervals with standard errors were analysed to test if certain major diagnosis categories (MDC) were statistically significantly more affected by differing expertise results than others. In 280 of the total 402 tested hospital cases, the 2 MDK raters independently reached the same G-DRG results; in 122 cases the G-DRG case sums determined by the 2 raters differed (agreement 70%; CI 65.2-74.1). Different DRG results between the 2 experts occurred regularly in the entire MDC spectrum. No MDC chapter in which significant differences between the 2 raters arose could be identified. The results of our study demonstrate an almost 70% agreement in the evaluation of hospital cost accounts by 2 independently operating MDK. This result leaves room for improvement. Optimisation potentials can be recognised on the basis of the results. Potential for improvement was established in combination with regular further training and the expansion of binding internal code recommendations as well as exchange of code-relevant information among experts in internal forums. The presented model is in principle suitable for cross-border examinations within the MDK system with the advantage that

    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.

    The objective of the present pluridisciplinary study was to contribute to determine how a diversity of audience differently appreciates several versions resulting from different "restoration" treatments of one single original lyrical recording. We present here a joint analysis coupling psychological and linguistic analyses with acoustic descriptions on a unique research object: a Caruso's piece of song diversely remastered on commercial CDs. Thirty-two subjects were selected contrasted on age ("younger than 30 years" and "older than 60 years") related with their different experience of earlier technical recording devices (rendering through devices such as radio, 78rpm records, CD...) and on expertise concerning musical acoustics (acousticians and/or musicians vs ordinary music lovers). Eleven excerpts of reediting of an opera record interpreted by Caruso were selected from what could found on the market. The listening protocol involved a free categorization task and the selection of excerpts on preference judgments. Each task involved subjects' free commentaries about their choices as a joint output from psychological processing. A cluster analysis scaffold by a psycholinguistic processing of the verbal comments of the categories allowed to identify both commonalities and differences in groupings excerpts by the different groups of the subjects, along a diversity of criteria, varying according to age and expertise. Each excerpt can therefore be characterized both according to psychological and to acoustic criteria. This study has enabled us to develop the idea that a lyric voice is a multifaced object (cultural, esthetic, technical, physical), acoustic parameters being linked to the various sensory experiences and expertises of appraisers. Such pluridisciplinary research and the coupling of the correlated multiplicity of methodologies we developed acknowledge for a better understanding of listening practices and music-lover assessments here concerned with a

    Full Text Available The Relative Age Effect (RAE in sport has been targeted by many research studies. The objective of this study was to analyze, in amateur clubs, the RAE of soccer players, according to the sport expertise level of the team (e.g., A, B, C and subsequent that they belong to within the same game category. 1,098 soccer players in formative stages took part in the study, with ages varying between 6 and 18 years old (U8 to U19 categories. All of them were members of 4 Spanish federated clubs. The birth dates were classified into 4 quartiles (Q1 = Jan-Mar; Q2 = Apr-Jun; Q3 = Jul-Sept; Q4 = Oct-Decaccording to the team they belonged to. The results obtained in the chi-squared test and d value (effect size revealed the existence of RAE in the teams with the highest expertise level, “A” (X2 = 15.342, p = .002, d = 0.4473 and “B” (X2 = 10.905, p = .012, d = 0.3657. However, in the lower level teams, “C and subsequent”, this effect was not observed. Present findings show that players born during the first months of the year tend to be selected to play in teams with a higher sport expertise level of each category, due to their physical maturity. Consequently, this causes differences in terms of the experience they accumulate and the motivation that this creates in these players.

  17. Visual strategies underpinning the development of visual-motor expertise when hitting a ball.

    It is well known that skilled batters in fast-ball sports do not align their gaze with the ball throughout ball-flight, but instead adopt a unique sequence of eye and head movements that contribute toward their skill. However, much of what we know about visual-motor behavior in hitting is based on studies that have employed case study designs, and/or used simplified tasks that fall short of replicating the spatiotemporal demands experienced in the natural environment. The aim of this study was to provide a comprehensive examination of the eye and head movement strategies that underpin the development of visual-motor expertise when intercepting a fast-moving target. Eye and head movements were examined in situ for 4 groups of cricket batters, who were crossed for playing level (elite or club) and age (U19 or adult), when hitting balls that followed either straight or curving ('swinging') trajectories. The results provide support for some widely cited markers of expertise in batting, while questioning the legitimacy of others. Swinging trajectories alter the visual-motor behavior of all batters, though in large part because of the uncertainty generated by the possibility of a variation in trajectory rather than any actual change in trajectory per se. Moreover, curving trajectories influence visual-motor behavior in a nonlinear fashion, with targets that curve away from the observer influencing behavior more than those that curve inward. The findings provide a more comprehensive understanding of the development of visual-motor expertise in interception. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Performing musicians invest thousands of hours becoming experts in a range of perceptual, attentional, and cognitive skills. The duration and intensity of musicians' training - far greater than that of most educational or rehabilitation programs - provides a useful model to test the extent to which skills acquired in one particular context (music) generalize to different domains. Here, we asked whether the instrument-specific and more instrument-general skills acquired during professional violinists' and pianists' training would generalize to superior performance on a wide range of analogous (largely non-musical) skills, when compared to closely matched non-musicians. Violinists and pianists outperformed non-musicians on fine-grained auditory psychophysical measures, but surprisingly did not differ from each other, despite the different demands of their instruments. Musician groups did differ on a tuning system perception task: violinists showed clearest biases towards the tuning system specific to their instrument, suggesting that long-term experience leads to selective perceptual benefits given a training-relevant context. However, we found only weak evidence of group differences in non-musical skills, with musicians differing marginally in one measure of sustained auditory attention, but not significantly on auditory scene analysis or multi-modal sequencing measures. Further, regression analyses showed that this sustained auditory attention metric predicted more variance in one auditory psychophysical measure than did musical expertise. Our findings suggest that specific musical expertise may yield distinct perceptual outcomes within contexts close to the area of training. Generalization of expertise to relevant cognitive domains may be less clear, particularly where the task context is non-musical. Copyright © 2014 Elsevier B.V. All rights reserved.

    2010-02-01

    Recently, the importance of effective maintenance in nuclear power plants (NPPs) has been emphasized and research into effective maintenance by adopting mobile maintenance aids (MMAs) have been attempted. MMAs are currently used during operation and maintenance in NPPs, but no method that considers the limitations of mobile devices has been proposed. For improved and effective use, an MMA display design method based on abstraction hierarchy (AH) is proposed and its design considerations are discussed in this study. Six levels of abstraction hierarchy are proposed in this paper to classify the maintenance information. By classifying and organizing maintenance information using AH, maintenance information can be used effectively by users either high or low levels of expertise. When information classification has been finished, the information requirements and relationships for MMA design is extracted from the analysis of the AH result. Representative human-machine interface (HMI) guidelines issued by the US NRC, which are generally used in NPPs, are applied. With the considerations of MMA design analysis and practical guidelines, AH-based MMA is designed for maintenance tasks. An experiment is conducted using the AH-based MMA in order to estimate the effectiveness of the proposed method for maintenance tasks and to identify design considerations to enhance the proposed MMAs. The result indicated that an AH-based manual was more effective than a conventional manual in terms of task completion time and number of errors. The workload for the AH-based manual was estimated to be less than the conventional manual for low levels of expertise. However, a conventional manual was more comprehensive than the proposed manual and the steps contained in the maintenance manual were easier to remember. As the level of expertise increases, subjects tended to follow more abstract information while the number of navigations decreased. It is believed that when mobile devices become

  1. Experts, meta-expertise and mediators. Ethical oversight of research in multidisciplinary scenarios

    2016-07-01

    Full Text Available Based on a case study drawn from the written records of a Colombian Research Ethics Committee (rec, this article discusses the impact that its multidisciplinary nature has on its decision-making processes. recs are analyzed as “boundary organizations” in which experts from different disciplines can meet. Additionally, recs are viewed as contemporary socio-epistemic arenas in which research ethics are produced. It was found that multiple expertise is often seen by some of its members as an «anomaly» which impedes ordinary work and ideally should be avoided. During the assessment of research projects the rec sought to manage this task through homogenizing decision-making processes in accordance with the expertise of some of its members, avoiding the convergence of «communities of practice.» Furthermore, the members of the rec frequently base their decisions either on their own ethical judgments, or by mirroring those of more qualified reviewers. This dynamic is largely a consequence of «meta-expertise,» that is to say, rec members’ ability or legitimacy to judge expert knowledge which they do not possess. It is concluded that researchers have wide possibilities to interpret and define the ethical dimension of their work. Within local practices of ethical reviews, researchers act as «interactional» actors able to assess and communicate recs about their own ethics. Paradoxically, despite their character as a public setting for multidisciplinary dialogue, recs end up being spaces in which the professional esotericism of disciplinary communities is reaffirmed and the socio-epistemic authority of experts reinforced.

  2. Emergency management at the boundary between expertise and decision: which role for CBRN-E atmospheric dispersion and impact assessment modeling?

    Environmental and health impact assessment of accidental or intentional releases of potentially hazardous materials in the atmosphere is increasingly supported by the development of modeling tools. Their potential to assess the spatial and temporal extent and severity of toxic plumes contributes to their growing development as CBRN-E emergency support tools. However, the Fukushima nuclear accident underlined that their support is not yet optimal regarding civil security organizations in charge of population protection. This research therefore tends to clarify the role of these modelling tools in emergency management. For this purpose, interviews and observations of crisis exercises have been conducted. This study suggests that nowadays, CBRN-E emergency management takes place in a sense making co-constructing process between CBRN-E experts and emergency managers contributing to the achievement of consensus in the decision making process. This study also highlights the key role played by the crisis center, regarding its proper organizational structure as a sharing place between actors with complementary expertise and experience, in the perception and response to changing circumstances. Thus, this study suggests that by providing situation assessment results, modeling tools meet the current practices both in terms of emergency support tools used for civilian protection organization and in respect of each actors' contributions. In this perspective, these modelling tools are likely to end up being part of the development of crisis management support tools for building a collective representation of the CBRN-E situation between expertise and decision.

  7. Authority, Expertise, and Impression Management: Gendered Professionalization of Chemists in the Academy

    Science.gov (United States)

    Hirshfield, Laura Ellen

    Women face more barriers to their success than their men counterparts in science, technology, engineering, and math (STEM) disciplines. While much of the research on women's experience in science has focused on their entry into or exit out of STEM fields (the "leaky pipeline"), less is known about the obstacles that women scientists face at work, due to the dearth of ethnographic work exploring gender and day-to-day experiences in the academic workplace. Using data from a qualitative study of graduate students and postdoctoral fellows in chemistry involving over 120 hours of ethnographic observation and 40 semi-structured interviews, I focus specifically on the gendered nature of authority, expertise, and impression management to investigate several of the obstacles women scientists face at work. In the first chapter, I investigate men and women graduate students' and postdocs' expectations of expertise. I argue that overall, men are more likely than their women peers to be seen as experts in chemistry. As a result, men graduate students benefit from more practice with skills that are applicable to their future careers: applying scientific knowledge to relevant questions and communicating this information to others. In the second chapter, I focus on gender and graduate student socialization. I find that the link between men, science, and academia creates a context in which men do not need to work as hard to establish their claim to scientific authority. Therefore, men are able to perform masculinity in varied and complex ways, while women, who do not embody masculinity, feel more pressure to conform to strict norms of competition that are associated with traditional masculinity. In the last chapter, I discuss the impression management strategies that men and women chemists-in-training use to navigate authority and expertise. I find that men are more likely than women to employ interactional styles that feature their expertise when in group situations, while women

    The difficulties in sharing tacit knowledge may compromise the safe performance of high-reliability organisations. This threat has been recognised in nuclear power plants worldwide, owing to the risk of simultaneous retirements. In this study, the nature of tacit knowledge in Finnish nuclear power plants was examined and the expertise of nuclear workers modelled. The results of this interview study showed that the tacit nuclear knowledge can be classified in two dimensions: technical and contextual. According to this classification, the employees in plants can be categorised in four categories: the experts; the novices; the technical specialists; the context sensitives. (author)

  12. Global reach: Red Deer oilfield expertise, not least in taming disasters, lures international clientele

    Lorenz, A.

    2002-10-07

    The rise to international prominence of two Red Deer, Alberta, firms --Safety Boss and Red Flame -- by performing heroic feats in Kuwait's flaming oil fields, are chronicled. These two firms, along with several others in Red Deer, provide expertise in fire fighting that is sought after by petroleum companies in the farthest corners of the world. Red Deer companies can be found training Kazakhs, Russians, Kuwaitis, Iranians, and Turkmen in fighting oil well fires. Red Flame, for example developed a method called 'hot-tapping' while fighting blazing oil well fires in Kuwait, which they have since extended by developing hot-tapping equipment that would work on the highest pressure wells in the world. Last summer Red Flame personnel trained a Schlumberger crew in Kazakhstan working on custom-designed equipment that could perform at pressures of 5,000 psi. Red Flame also designed 'extended reach' hot-tapping in response to a request from Petro-Canada. Meanwhile, Safety Boss, the oldest and best known oil well fire fighting company in Canada, boasts of having extinguished 180 wells in their 1991 stint in Kuwait, while their closest competitor, Texas-based Wild Well, doused only 117. With improved safety policies and procedures the number of oil well blow-outs diminished dramatically in recent years, but there are always opportunities for the Red Deer expertise somewhere around the world.

    The current study examined children's willingness to accept novel information from expert informants with nontraditional gender role interests. Four- to 8-year-olds heard conflicting information about traditionally feminine or masculine domains from a gender counter-stereotypical expert (e.g., a boy with expertise in ballet) and a layperson of the other gender (e.g., a girl with little knowledge about ballet). Participants were asked which informant was correct, who they would prefer to learn from in the future, and to rate their liking of each informant. Overall, participants selected the gender counter-stereotypical expert as correct. Four- to 5-year-olds reported a preference to learn from same-gender participants in the future irrespective of expertise, whereas 6- to 8-year-olds reported wanting to learn from counter-stereotypical experts. Boys showed relatively greater acceptance of information from a male counter-stereotypical expert than from a female counter-stereotypical expert. Although participants reported greater liking of same-gender informants, liking evaluations were largely positive irrespective of gender norm deviations. Implications for children's acceptance of gender nonconforming activities are discussed. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available This research aimed to identify which skills are considered most relevant to the practice of criminal accounting expertise in Brazil. As in international research, the skills perceived as most relevant were written communication, deductive analysis and critical thinking. Among the less relevant skills were the interview and the solution and negotiation of conflicts. In the second part, while experts and delegates jointly consider written communication to be the most present skills, delegates diverge from experts in terms of critical thinking and serenity. In addition, the respondents indicated skills that had not been investigated, and the most cited skills were proactivity, objectivity and updating. In the light of forensic accounting, the research method used was the survey, using a predefined questionnaire with open and closed questions, which 144 respondents answered. The study was divided into three parts: the first about the perceived relevance of the skills, the second about the perceived practical application of skills and the third part allowed the respondents to contribute with suggestions of skills that were considered relevant but did not figure among the skills investigated. The study contributes to the establishment of curricular guidelines for undergraduate and postgraduate courses related to the training of skills considered relevant for the training of future professionals and for the improvement of criminal accounting experts. Finally, we observe that the skills investigated and suggested can contribute to all areas of accounting expertise.

    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.

    Full Text Available Representational momentum (RM has been found to be magnified in experts (e.g., sport players with respect to both real and implied motion in expert-familiar domains. However, it remains unclear whether similar effects can be achieved in expert-unfamiliar domains, especially within the context of implied motion. To answer this question, we conducted two independent experiments using an implied motion paradigm and examined the expert effects of badminton training on RM in both adult and child players. In Experiment 1, we used a cross-sectional design and compared RM between adult professional badminton players and matched controls. The results revealed significantly enhanced RM for adult players, supporting the expert effect in expert-unfamiliar domains for implied motion. However, cross-sectional studies could not ascertain whether the observed expert effect was due to innate factors or expertise acquirement. Therefore, in Experiment 2, we used a longitudinal design and compared RM between two groups of child participants, naming child players who had enrolled professional badminton training program at a sports school and age-matched peer non-players who attended an ordinary primary school without sports training. Before training, there were no differences in RM among child players, their non-player peers, and adult non-players. However, after 4 years of badminton training, child players demonstrated significantly enhanced RM compared to themselves prior to training. The increased RM observed in both adult and child players suggests that badminton expertise modulates implied motion RM.

    The paper investigates the multiple public-private exchanges and cooperation involved in the installation and development of CCTV surveillance at Geneva International Airport. Emphasis is placed on the interacting forms of authority and expertise of five parties: the user(s), owner and supplier of the camera system, as well as the technical managers of the airport and the Swiss regulatory bodies in airport security. While placing the issues of airport surveillance in the particular context of a specific range of projects and transformations relating to the developments of CCTV at Geneva Airport, the paper not only provides important insights into the micro-politics of surveillance at Geneva Airport, but aims to re-institute these as part of a broader 'problematic': the mediating role of expertise and the growing functional fragmentation of authority in contemporary security governance. On this basis, the paper also exemplifies the growing mutual interdependences between security and business interests in the ever growing 'surveillant assemblage' in contemporary security governance.

  18. Behavioral and subcortical signatures of musical expertise in Mandarin Chinese speakers.

    Directory of Open Access Journals (Sweden)

    Caitlin Dawson

    Full Text Available Both musical training and native language have been shown to have experience-based plastic effects on auditory processing. However, the combined effects within individuals are unclear. Recent research suggests that musical training and tone language speaking are not clearly additive in their effects on processing of auditory features and that there may be a disconnect between perceptual and neural signatures of auditory feature processing. The literature has only recently begun to investigate the effects of musical expertise on basic auditory processing for different linguistic groups. This work provides a profile of primary auditory feature discrimination for Mandarin speaking musicians and nonmusicians. The musicians showed enhanced perceptual discrimination for both frequency and duration as well as enhanced duration discrimination in a multifeature discrimination task, compared to nonmusicians. However, there were no differences between the groups in duration processing of nonspeech sounds at a subcortical level or in subcortical frequency representation of a nonnative tone contour, for fo or for the first or second formant region. The results indicate that musical expertise provides a cognitive, but not subcortical, advantage in a population of Mandarin speakers.

    Considerable research has focused on how basic visual features are maintained in working memory, but little is currently known about the precision or capacity of visual working memory for complex objects. How precisely can an object be remembered, and to what extent might familiarity or perceptual expertise contribute to working memory performance? To address these questions, we developed a set of computer-generated face stimuli that varied continuously along the dimensions of age and gender, and we probed participants' memories using a method-of-adjustment reporting procedure. This paradigm allowed us to separately estimate the precision and capacity of working memory for individual faces, on the basis of the assumptions of a discrete capacity model, and to assess the impact of face inversion on memory performance. We found that observers could maintain up to four to five items on average, with equally good memory capacity for upright and upside-down faces. In contrast, memory precision was significantly impaired by face inversion at every set size tested. Our results demonstrate that the precision of visual working memory for a complex stimulus is not strictly fixed but, instead, can be modified by learning and experience. We find that perceptual expertise for upright faces leads to significant improvements in visual precision, without modifying the capacity of working memory.

  2. 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.

    We review a series of experiments aimed at studying pitch processing in music and speech. These studies were conducted with musician and non musician adults and children. We found that musical expertise improved pitch processing not only in music but also in speech. Demonstrating transfer of training between music and language has interesting applications for second language learning. We also addressed the issue of whether the positive effects of musical expertise are linked with specific predispositions for music or with extensive musical practice. Results of longitudinal studies argue for the later. Finally, we also examined pitch processing in dyslexic children and found that they had difficulties discriminating strong pitch changes that are easily discriminate by normal readers. These results argue for a strong link between basic auditory perception abilities and reading abilities. We used conjointly the behavioral method (Reaction Times and error rates) and the electrophysiological method (recording of the changes in brain electrical activity time-locked to stimulus presentation, Event-Related brain Potentials or ERPs). A set of common processes may be responsible for pitch processing in music and in speech and these processes are shaped by musical practice. These data add evidence in favor of brain plasticity and open interesting perspectives for the remediation of dyslexia using musical training.

  4. Time course of the influence of musical expertise on the processing of vocal and musical sounds.

    Previous functional magnetic resonance imaging (fMRI) studies have suggested that different cerebral regions preferentially process human voice and music. Yet, little is known on the temporal course of the brain processes that decode the category of sounds and how the expertise in one sound category can impact these processes. To address this question, we recorded the electroencephalogram (EEG) of 15 musicians and 18 non-musicians while they were listening to short musical excerpts (piano and violin) and vocal stimuli (speech and non-linguistic vocalizations). The task of the participants was to detect noise targets embedded within the stream of sounds. Event-related potentials revealed an early differentiation of sound category, within the first 100 ms after the onset of the sound, with mostly increased responses to musical sounds. Importantly, this effect was modulated by the musical background of participants, as musicians were more responsive to music sounds than non-musicians, consistent with the notion that musical training increases sensitivity to music. In late temporal windows, brain responses were enhanced in response to vocal stimuli, but musicians were still more responsive to music. These results shed new light on the temporal course of neural dynamics of auditory processing and reveal how it is impacted by the stimulus category and the expertise of participants.

  5. Word reading and translation in bilinguals: The impact of formal and informal translation expertise

    2014-11-01

    Full Text Available Studies on bilingual word reading and translation have examined the effects of lexical variables (e.g., concreteness, cognate status by comparing groups of non-translators with varying levels of L2 proficiency. However, little attention has been paid to another relevant factor: translation expertise (TI. To explore this issue, we administered word reading and translation tasks to two groups of non-translators possessing different levels of informal TI (Experiment 1, and to three groups of bilinguals possessing different levels of translation training (Experiment 2. Reaction-time recordings showed that in all groups reading was faster than translation and unaffected by concreteness and cognate effects. Conversely, in both experiments, all groups translated concrete and cognate words faster than abstract and non-cognate words, respectively. Notably, an advantage of backward over forward translation was observed only for low-proficiency non-translators (in Experiment 1. Also, in Experiment 2, the modifications induced by translation expertise were more marked in the early than in the late stages of training and practice. The results suggest that TI contributes to modulating inter-equivalent connections in bilingual memory.

  6. The influence of reading expertise in mirror-letter perception: Evidence from beginning and expert readers

    The visual word recognition system recruits neuronal systems originally developed for object perception which are characterized by orientation insensitivity to mirror reversals. It has been proposed that during reading acquisition beginning readers have to “unlearn” this natural tolerance to mirror reversals in order to efficiently discriminate letters and words. Therefore, it is supposed that this unlearning process takes place in a gradual way and that reading expertise modulates mirror-letter discrimination. However, to date no supporting evidence for this has been obtained. We present data from an eye-movement study that investigated the degree of sensitivity to mirror-letters in a group of beginning readers and a group of expert readers. Participants had to decide which of the two strings presented on a screen corresponded to an auditorily presented word. Visual displays always included the correct target word and one distractor word. Results showed that those distractors that were the same as the target word except for the mirror lateralization of two internal letters attracted participants’ attention more than distractors created by replacement of two internal letters. Interestingly, the time course of the effects was found to be different for the two groups, with beginning readers showing a greater tolerance (decreased sensitivity) to mirror-letters than expert readers. Implications of these findings are discussed within the framework of preceding evidence showing how reading expertise modulates letter identification. PMID:24273596

    Art is one of life’s great joys, whether it is beautiful, ugly, sublime or shocking. Aesthetic responses to visual art involve sensory, cognitive and visceral processes. Neuroimaging studies have yielded a wealth of information regarding aesthetic appreciation and beauty using visual art as stimuli, but few have considered the effect of expertise on visual and visceral responses. To study the time course of visual, cognitive and emotional processes in response to visual art we investigated the event-related potentials (ERPs) elicited whilst viewing and rating the visceral affect of three categories of visual art. Two groups, artists and non-artists viewed representational, abstract and indeterminate 20th century art. Early components, particularly the N1, related to attention and effort, and the P2, linked to higher order visual processing, was enhanced for artists when compared to non-artists. This effect was present for all types of art, but further enhanced for abstract art (AA), which was rated as having lowest visceral affect by the non-artists. The later, slow wave processes (500–1000 ms), associated with arousal and sustained attention, also show clear differences between the two groups in response to both type of art and visceral affect. AA increased arousal and sustained attention in artists, whilst it decreased in non-artists. These results suggest that aesthetic response to visual art is affected by both expertise and semantic content. PMID:27242497

    Full Text Available In a highly competitive, rapidly changing higher education market, universities need to be able to generate pedagogical expertise quickly and ensure that it is applied to practice. Since teaching approaches are constantly evolving, partly responding to emerging learning technologies, there is a need to foster ways to keep abreast on an ongoing basis. This paper explores how a small-scale project, the Teaching Online Panel (TOP, used scholarship investigations and a bottom-up approach to enhance one particular aspect of academic practice – online learning and teaching. The experiences of TOP are useful for identifying:  • how a scholarship approach can help develop academic expertise • its contribution to enhancing understanding of staff’s different roles in the University • ways of developing the necessary supportive network for those undertaking such scholarship • the effectiveness of staff development which is peer-led rather than imposed from above • how practical examples can stimulate practice development • the relevance of literature on communities of practice and landscapes of practice for scholarship • the important role of ‘brokers’ to facilitate the dissemination of scholarship findings • the benefits to the brokers’ own professional roles • the challenges of sustaining such an approach and lessons learnt. This study has relevance for those involved in supporting scholarship or delivering staff development in Higher Education.

    SITEX is a 24 months FP7 Euratom project (from January 2012 to December 2013) led by IRSN and bringing together organisations representing technical safety organisations and nuclear safety authorities performing technical and scientific assessment of geological disposals for radioactive waste in the framework of their respective national regulatory review process of the safety case. Civil society outreach specialists of interaction with civil society are also involved in the project. SITEX aims at establishing the conditions required for developing sustainable interactions among experts from various horizons (nuclear safety authorities, technical safety organisations, civil society organisations..) capable of developing and coordinating joint and harmonized activities in relation with the safety assessment of the safety case. Among foreseen activities, partnership with the civil society experts is considered as a key function of the future network in order to contribute in enhancing trust in the decision making process. The SITEX program of work is split into a set of six workpackages that address technical and organizational issues allowing in fine to propose a structure of the activities and operating modes of the future network. These issues relate on the one hand to the study of the potential for sharing and developing technical expertise practices independently from the expertise developed by waste management organisations, on the other hand on the ability to implement coordinated R and D programs run by technical safety organisations in order to develop the scientific knowledge necessary to perform technical assessments.

  10. Investing in Germany's nuclear expertise can reap international awards

    2015-07-15

    At the international expert conference, Annual Meeting on Nuclear Technology (AMNT 2015) in Berlin in May, there was a very welcome public admission from one of the German government's key policymakers. The director-general of the energy policy department at the Federal Ministry for Economic Affairs and Energy (Bundesministerium fuer Wirtschaft und Energie - BMWi), Thorsten Herdan, said the high level of expertise available throughout Germany's nuclear energy industry was greatly valued at home and abroad and must be retained. He rightly said that the country's technical competence and know-how ''will still be needed'' - despite the country's commitment to phasing out the use of nuclear at home under the politically-inspired 'energy transition' (Energiewende). The nuclear energy industry's commitment to identifying, training and nurturing a new generation of nuclear professionals is self evident. Perhaps what is needed now is for governments such as Germany's, whether supporters of nuclear power generation or not, to do more to endorse the importance of developing nuclear expertise. In the nuclear industry, governments will find a more than willing partner in supporting the training and education of the nuclear engineers and regulators of the future.

    Representational momentum (RM) has been found to be magnified in experts (e.g., sport players) with respect to both real and implied motion in expert-familiar domains. However, it remains unclear whether similar effects can be achieved in expert-unfamiliar domains, especially within the context of implied motion. To answer this question, we conducted two independent experiments using an implied motion paradigm and examined the expert effects of badminton training on RM in both adult and child players. In Experiment 1, we used a cross-sectional design and compared RM between adult professional badminton players and matched controls. The results revealed significantly enhanced RM for adult players, supporting the expert effect in expert-unfamiliar domains for implied motion. However, cross-sectional studies could not ascertain whether the observed expert effect was due to innate factors or expertise acquirement. Therefore, in Experiment 2, we used a longitudinal design and compared RM between two groups of child participants, naming child players who had enrolled professional badminton training program at a sports school and age-matched peer non-players who attended an ordinary primary school without sports training. Before training, there were no differences in RM among child players, their non-player peers, and adult non-players. However, after 4 years of badminton training, child players demonstrated significantly enhanced RM compared to themselves prior to training. The increased RM observed in both adult and child players suggests that badminton expertise modulates implied motion RM. PMID:28970810

    There is little research investigating the maintenance of perceptual-cognitive expertise in general and even less comparing coaches of different ages. The aim of this study was to test for perceptual-cognitive differences between age groups, licence levels, and their interaction. This study investigated differences in skilled performance between young and middle-aged coaches of three different skill levels. Participants performed an accuracy-oriented pattern recall (mean distance in pixel) and a time-oriented flicker test (mean detection time in ms). There were some significant differences between age groups and between skill groups for both tests, but no interactions. For the pattern recall test, the effect sizes were larger for skill level differences, while for the flicker test effects were larger for ageing. These results suggest coaches are able to maintain accuracy skills better than reaction timed tasks. This is in line with findings on speeded performance in general populations, which show declines with age. Moreover, results also support findings on perceptual expertise in skills where accuracy was important.

This piece uses a collection of locals from around Essex Massachusetts to shape and delimit an interrogation of post-reality in contemporary America. It explores the notion of crisis, the possibility of a crisis of empire that may or may not emerge in a media-space that does not allow crisis of empire to be mentioned and relations this maybe-crisis to the various levels of economic dysfunction that have become evident since late 2008. But mostly this piece explores ways in which particular stories about particular people do and do not link/link to these larger-scale narratives.

  16. High-resolution imaging of expertise reveals reliable object selectivity in the fusiform face area related to perceptual performance.

    2012-10-16

    The fusiform face area (FFA) is a region of human cortex that responds selectively to faces, but whether it supports a more general function relevant for perceptual expertise is debated. Although both faces and objects of expertise engage many brain areas, the FFA remains the focus of the strongest modular claims and the clearest predictions about expertise. Functional MRI studies at standard-resolution (SR-fMRI) have found responses in the FFA for nonface objects of expertise, but high-resolution fMRI (HR-fMRI) in the FFA [Grill-Spector K, et al. (2006) Nat Neurosci 9:1177-1185] and neurophysiology in face patches in the monkey brain [Tsao DY, et al. (2006) Science 311:670-674] reveal no reliable selectivity for objects. It is thus possible that FFA responses to objects with SR-fMRI are a result of spatial blurring of responses from nonface-selective areas, potentially driven by attention to objects of expertise. Using HR-fMRI in two experiments, we provide evidence of reliable responses to cars in the FFA that correlate with behavioral car expertise. Effects of expertise in the FFA for nonface objects cannot be attributed to spatial blurring beyond the scale at which modular claims have been made, and within the lateral fusiform gyrus, they are restricted to a small area (200 mm(2) on the right and 50 mm(2) on the left) centered on the peak of face selectivity. Experience with a category may be sufficient to explain the spatially clustered face selectivity observed in this region.

    2014-11-01

    Full Text Available 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 specialisation 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 analysed 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. Thirdly, it used a very tight experiment design, including the experimenter being blind to expertise level and genre specialisation 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 specialisation 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.

    2015-03-01

    Full Text Available How, if at all, does the Commission’s expertise inform intergovernmental decision-making within the EU? In this article, we aim to capture the relationship between the Commission’s expertise and its influence within intergovernmental policy-areas through a study of Commission influence in two least likely sectors: security and defence policies (military mission Atalanta and EU Maritime Security Strategy and external migration (EU mobility partnerships with third countries. In these cases we observe that the Commission strongly informs policy developments even though it has only limited formal competences. To explore whether and, if so, how this influence is linked to its expertise, we develop and consider two hypotheses: The expert authority hypothesis and the expert arguments hypothesis. To identify possible additional channels of influence, we also consider the relevance of two alternative hypotheses: The strategic coalition hypothesis and the institutional circumvention hypothesis. We find that the Commission’s use of its expertise is indeed key to understanding its de facto influence within policy-areas where its formal competences remain limited. Our findings add to the existing literature by revealing how expertise matters. Specifically, our cases show that the Commission informs intergovernmental decision-making by successfully linking discussions to policy-areas where it holds expert authority. However, the Commission also informs EU policies by circumventing the formal lines of intergovernmental decision-making, and by cooperating with member states that share its preference for further integration.

    2004-12-01

    Expertise test was the object of many controversies in the previous Civil Prosecution Law (CPL) from the way of naming the experts to the difficulties in the receiving payment. The new CPL uses the social process as model and provides civil justice with an agile and guaranteeing procedure. The CPL provides the expert test with a greater amplitude and new range, and should be used at the time of the lawsuit and openly seen. The experts should assume the defense of their arguments and be subjected to the objections of the contrary party. The expert's test becomes a mixed documental and personal test. It also modifies the way of naming the experts and the acceptance that may condition the allocation of funds in the amount considered necessary. The objection is limited to the experts named judicially, it being possible to eliminate them, however, the reason for it should be justified.
