A number of previous studies have found that wine experts can more accurately discriminate between and describe wine samples than novices. However, the mechanisms that underlie these disparities remain unclear. This collection of studies is an investigation of whether the expert advantage is based on long-term memory structures, such as found for other obviously more cognitive skills, such as chess and bridge expertise. Experiments 1, 2 and 3 investigated whether wine experts are better than novices in recall of wine descriptions. It was hypothesised that experts would show more accurate recall than novices, although only when the descriptions were configured in a meaningful manner, that is, consistent with grape varieties commonly grown in Australia. The findings were as expected, with experts showing impaired recall for descriptions that did not match any grape variety (Experiment 2). In addition, expert recall was superior on an incidental task (Experiment 3), when recall was unexpected, suggesting that experts automatically refer to verbal long-term memory structures during a wine-related task. These structures consist of wine-relevant terms, and are organised by their relationship to grape varieties, and more broadly, grape colour. Experiments 4, 5, 6 and 7 investigated the role of the above-mentioned long-term memory structures in expert descriptive ability. The results supported their involvement, since expert�s ability to identify components was affected by sample configuration (Experiment 6) in a similar way to that found for recall of wine descriptions. Additional evidence comes from the finding that, novices, when provided with a small set of grape-relevant labels during a descriptive task, performed better than subjects given either no list or a long list of labels relevant to all the different grape varieties (Experiment 4). While experts correctly identified more flavours than novices, they also made more errors (Experiment 6), suggesting that verbal long-term memory structures do not increase the accuracy of the identification of aromas and flavours by experts. Rather, they inform experts as to which labels are likely to be correct for particular styles of wine. Experiments 8, 9 and 10 investigated both the discrimination performance of novices, intermediates and experts, as well as the role of long-term memory structures in any expert discriminative advantage. Experts (Experiments 8 and 10) and intermediates (Experiment 9) showed greater powers of discrimination than novices. However, results were equivocal in relation to the role of verbal long-term memory structures (Experiment 10), suggesting that other factors, such as perceptual learning and or memory, may be important in the expert discriminative advantage. Overall, results from these studies illustrate that long-term memory structures are essential, not only in domains of expertise that are obviously based on cognitive skills, but also that of descriptive ability with respect to wine. However, unlike in other domains, these structures do not serve to improve the relative accuracy of descriptive performance, at least with regard to aromas and flavours.

In a rapidly changing business environment, it is difficult for enterprises to achieve their objectives by functional structures only. When organizational tasks become more complex, ¡§team¡¨ plays an important role on overcoming these challenges and helps achieving team performance. As a result, researches on team effectiveness have becoming ever more important today. The purpose of this study includes below: 1.Users should be involved because they possess knowledge which developers don¡¦t have but is required for system development. They should be viewed as partners with the developers that could make team to get target. 2.The most critical resource for knowledge teams is expertise, or specialized skills and knowledge, but the mere presence of expertise on a team is insufficient to produce high-quality work. Expertise must be managed and coordinated in order to leverage its potential. That is, teams must be able to manage their skill and knowledge interdependencies effectively through user and developer¡¦s good relationship. 3.The six facets of the Teamwork Quality (TWQ) construct, i.e., communication, coordination, balance of member contributions, mutual support, effort, and cohesion, are specified. TWQ shows a strong association with team members' personal success.

La grammaire, discipline indéfectiblement liée à l’écriture, semble reléguée au second plan depuis l’introduction de la notion de compétence de communication dans l’enseignement / apprentissage du français langue étrangère, à en croire un discours didactique répandu. Or, les pratiques des enseignants de français comme langue étrangère et seconde et les manuels de langue édités en France tendent à montrer une permanence des activités grammaticales. Ce paradoxe nous a conduite à nous interroger sur le discours grammatical d’ouvrages conçus dans un contexte spécifique d’enseignement du français, pour des apprenants partageant une même langue première. Nous avons procédé à l’étude de vingt-six (26) ouvrages de grammaires produits en Italie entre 1970 et 2011. L’analyse des classes grammaticales du point de vue de leurs dénominations mais aussi de leurs définitions ainsi que de la description/explication des faits de langue, effectuée par rapport à une description grammaticale dite « de référence » du français, a révélé des phénomènes de contextualisation diffus et constants tout au long de la période analysée. Une typologie des différentes formes a été dégagée, mettant en évidence quatre catégories de contextualisation, toutes fondées sur la langue première des apprenants et sa grammatisation spécifique. Une relation est établie entre cette forme d’adaptation du discours grammatical de référence du français et les savoirs d’expertise professionnelle des enseignants, ce qui amène à reconsidérer les liens que l’enseignement et la description des langues ont toujours entretenus dans le monde occidental. / According to common discourse in the field of didactics, grammar, considered as an intimate related discipline to writing practices, seems to be often overshadowed since the introduction of the concept of the communicative competence in French as a foreign language teaching and learning. Nevertheless, the practices of teachers of French as a foreign or second language and the handbooks for language learning published in France certify a continuous presence of grammar activities in this field. The present study, based on this contradictory situation, seeks to analyse the grammatical discourse of handbooks specifically conceived for learners of French as a foreign language who share a common first language. With this aim, we review twenty six (26) books of grammar edited in Italy between 1970 and 2011. The study begins by investigating the designation and definition of parts of speech and the description of language facts by comparing them to a reference description of French Grammar. We try to reveal how this description takes place through a constant and widespread, diffuse character throughout the analysed period. The study continues by establishing a typology of different forms based on four categories of contextualization, all derived from the learners’ first common language and its specific context grammatisation. Finally, in the perspective of reconsidering the long-lasting relationship between teaching and language description in the occidental world, we suggest possibilities for joining French grammatical reference discourse adaptation and teachers’ professional expertise knowledge.

This study examines the ways in which public participation in the production of scientific knowledge, influences the practices and expertise of the scientists in Galaxy Zoo, an online Big Data citizen science initiative. The need for citizen science in the field of Astronomy arose in response to the challenges of rapid advances in data gathering technologies, which demanded pattern recognition capabilities that were too advanced for existing computer algorithms. To address these challenges, Galaxy Zoo scientists recruited volunteers through their online website, a strategy which proved to be remarkably reliable and efficient. In doing so, they opened up the boundaries of scientific processes to the public. This shift has led to important outcomes in terms of the scientific discovery of new Astronomical objects; the creation and refining of scientific practices; and the development of new forms of expertise among key actors while they continue to pursue their scientific goals. This thesis attempts to answer the over-arching research question: How is citizen science shaping the practices and expertise of Galaxy Zoo scientists? The emergence of new practices and development of the expertise in the domain of managing citizen science projects were observed through following the work of the Galaxy Zoo scientists and in particular the Principal Investigator and the project's Technical Lead, from February 2010 to April 2013. A broadly ethnographic approach was taken, which allowed the study to be sensitive to the uncertainty and unprecedented events that characterised the development of Galaxy Zoo as a pioneering project in the field of data-intensive citizen science. Unstructured interviewing was the major source of data on the work of the PI and TL; while the communication between these participants, the broader Science Team and their inter-institutional collaborators was captured through analyses of the team emailing list, their official blog and their social media posts. The process of data analysis was informed by an initial conceptualisation of Galaxy Zoo as a knowledge production system and the concept of knowledge object (Knorr-Cetina,1999), as an unfolding epistemic entity, became a primary analytical tool. Since the direction and future of Galaxy Zoo involved addressing new challenges, the study demanded periodic recursive analysis of the conceptual framework and the knowledge objects of both Galaxy Zoo and the present examination of its development. The key findings were as follows. The involvement of public volunteers shaped the practices of the Science Team, while they pursued robust scientific outcomes. Changes included: negotiating collaborations; designing the classification tasks for the volunteers; re-examining data reduction methods and data release policies; disseminating results; creating new epistemic communities; and science communication. In addition, new kinds of expertise involved in running Galaxy Zoo were identified. The relational and adaptive aspects of expertise were seen as important. It was therefore proposed that the development of the expertise in running citizen science projects should be recognised as a domain-expertise in its own right. In Galaxy Zoo, the development of the expertise could be attributed to a combined understanding of: the design principles of doing good science; innovation in methods; and creating a dialogic space for scientists and volunteers. The empirical and theoretical implications of this study therefore lie in (i) identifying emergent practices in citizen science while prioritising scientific knowledge production and (ii) a re-examination of expertise for science in the emerging context of data-intensive science.
