Expert Opinion and Gastronomy: The Recipe for Success     

Véronique Chossat  Olivier Gergaud 《Journal of Cultural Economics》2003,27(2):127-141

Experts' opinions play an important role in the gastronomic market for the following reasons: information is imperfect and very costly to acquire and quality is, in large part, subjective and consumers need experts to define it. The number of guidebooks currently issued, their success (Michelin: 650,000 sold; GaultMillau: 200,000 sold) and the strong level of correlation generally obtained between prices and ratings or rankings (0.63 on average) for this class of activity illustrate this influence. Without experts, supply and demand would find it difficult to meet.Therefore, identifying the determinants of these evaluations of quality and then estimating their respective impact become relevant. According to the experts, the art of cooking is the only determinant that they take into account when selecting and then evaluating the chefs. For the chefs, the setting also appears to be a determinant and not the least important one.What is the best strategy to become a ``first rate'' chef? Would Alain Ducasse, one of the most famous French chefs, get the same rating in a roadside café as in a luxury restaurant? To answer these questions, a quality equation is estimated using an original database concerning 185 leading French chefs who have been selected in one of the most famous French guidebooks: GaultMillau (2000 edition). The results show that there are two strategies to become a ``first rate'' chef but that the art of cooking prevails over setting. This is in line with the observation that some gourmet restaurants tend to over-invest in luxurious surroundings.  相似文献   

Radiography of paintings: Limitations of transmission radiography and exploration of emission radiography using phosphor imaging plates     

Olivier Schalm  Lies Vanbiervliet  Peter Willems  Peter De Schepper 《文物保护研究》2014,59(1):10-23

Radiography in transmission mode is a well-established technique to visualize the internal structure of paintings. However, for many paintings the pictorial layer cannot be clearly visualized with conventional radiography because of interference from paint on the reverse, the material composition or the regular structure of supports or subsurface layers. Traditional lead white grounds in particular cause specific imaging problems not encountered with more modern white pigments such as zinc and titanium whites. A solution to this problem is radiography in emission mode. This study demonstrates and articulates those factors that can interfere with visualization of a painting's pictorial layer using transmission radiography as well as those that contribute to the effectiveness of emission radiography in visualizing such information. While emission radiography has been applied to the examination of paintings for over half a century, it is a cumbersome technique that is further complicated by the need to work under dim safelight illumination when X-radiographic film is used. Therefore, the use of computed radiography using storage phosphor imaging plates for emission radiography was also investigated.  相似文献   

Chinese communication characteristics: A Yin Yang perspective     

Tony Fang  Guy Olivier Faure 《Int J Intercult Relat》2011,35(3):320-333

Research on Chinese communication has so far focused on the understanding of the impact of traditional Confucian cultural values on Chinese communication characteristics. While this Confucian-oriented Chinese communication style remains meaningful and in many situations powerful in Chinese society and in communication between Chinese and western professionals, the paradox inherent in Chinese culture and communication has rarely been researched. Moreover, China's three decades of rapid economic progress and unprecedented interactions with the rest of the world have contributed to an emergent Chinese communication style, which differs from the traditional one. Based on the philosophical principle of Yin Yang, this paper provides a framework to capture the paradox and change of Chinese communication characteristics in today's changing Chinese society. Implications for how to communicate effectively with the Chinese from practitioners’ point of view are also discussed.  相似文献   

Critical thinking as the ability to sort and qualify the information available,to form one's own judgement     

Elena Pasquinelli  Olivier Richard 《European Journal of Education》2023,58(3):422-433

In an era marked by an excessive exposure to information and disinformation, this article explores how the public in France engages with critical thinking on the topics of scientific information and knowledge, as well as associated debates. First, a panel survey was carried out in 2022 by the science education centre Universcience in Paris in collaboration with the survey institute GECE. A total of 3,218 respondents participated in the survey in France. The survey questions focused on three themes: (1) the substantial relationship between respondents' scientific reasoning and critical thinking; (2) sources that respondents used for information, particularly on scientific subjects, to form an understanding of current events; (3) respondent relationships to discourses in the sciences and otherness in reasoning. In this study, critical thinking was defined as the ability to sort and make sense of available information and to question one's opinions. Also, the ability to discern trustworthy sources and information. In this approach, critical thinking is a condition for correctly assessing information on science topics. This is understood to include knowledge about science, its processes of knowledge production, and quality sources of information in the natural sciences. In this study, a Barometer of Critical Thinking was developed, and a survey was carried out. Survey results and the development of the barometer are described. Finally, we discuss how developing scientific literacy (knowledge about scientific facts, methods, practices and sources) is crucial in order to foster critical thinking on scientific information, knowledge, debates, and beyond.  相似文献   

Inference and evaluation of the multinomial mixture model for text clustering     

Loïs Rigouste  Olivier Cappé  François Yvon 《Information processing & management》2007

In this article, we investigate the use of a probabilistic model for unsupervised clustering in text collections. Unsupervised clustering has become a basic module for many intelligent text processing applications, such as information retrieval, text classification or information extraction.  相似文献   

Discussing Sexual Orientation and Gender in Classrooms: A Testimonial-Based Approach to Fighting Homophobia in Schools     

Gabrielle Richard  Olivier Vallerand  Marie-Pier Petit  Amélie Charbonneau 《The Educational forum》2015,79(4):421-435

Abstract

To fight homophobia in schools in Québec, many teachers rely on community organizations such as the Groupe de Recherche et d’Intervention Sociale (Research and Social Intervention Group) to address sexual diversity in class. This article documents major outcomes of these workshops as seen by students. Students identified topics related to sexuality and gender inversion as controversial, especially when involving men. The authors present how GRIS leaders decided to adapt intervention practices following such findings.  相似文献   

Back in the bazaar: taking Pierre Bourdieu to a trading room     

Olivier Godechot 《Journal of Cultural Economy》2016,9(4):410-429

Drawing on Pierre Bourdieu's theory of aesthetic judgment, this text offers an inductive account of financial reasoning inside a trading room. Driven to maximise bank profits, trading room operators do not find ‘one best way’. Rather they choose among several possible winning strategies: mathematical arbitrage, economic analysis, chartist analysis. These strategies differ sharply from one another in their conception of the market, method, proximity to scholarly knowledge, and legitimacy. We show that the choice of one method depends on a system of tastes and distastes that are both historical – depending on individuals’ social and educational background – and relational – depending on the individual's relative position within the trading room viewed as a field.  相似文献   

Just Getting By? Francophone Belgian Journalists Dealing with Dutch-language Sources in Their Public Broadcasting Service     

Olivier Standaert  Catherine Bouko  Astrid Vandendaele 《Journalism Practice》2020,14(6):664-678

ABSTRACT

In this article, we examine how the Dutch language is used when francophone Belgian journalists prepare and produce their reports—during all stages of the process—up until the actual broadcast. We conducted 16 qualitative interviews with TV news journalists employed by the Belgian French-speaking public broadcaster. Taking as a starting point the highly variable level of Dutch in the newsroom, we highlight four practices used by journalists when they have to cover a news story in Flanders or interview a Dutch speaker: avoidance, mutual assistance, specific efforts to deal with linguistic difficulties and what we call a “tactical use” of Dutch with the sources. This study reveals practices that are by no means a demonstration of excellent language skills. Journalists’ frequent lack of knowledge is compensated by a certain pragmatism: they aim to illustrate how their daily routines tackle a concrete problem in a relatively informal, flexible, and collective manner. Finally, we explore to what extent these practices impact journalistic performance and how the use of the Dutch language in the newsroom reflects the language divide in Belgium’s journalistic landscape.  相似文献   

The effects of psoas major and lumbar lordosis on hip flexion and sprint performance     

Copaver K  Hertogh C  Hue O 《Research quarterly for exercise and sport》2012,83(2):160-167

In this study, we analyzed the correlations between hip flexion power; sprint performance, lumbar lordosis (LL) and the cross-sectional area (CSA) of the psoas muscle (PM). Ten young adults performed two sprint tests and isokinetic tests to determine hip flexion power. Magnetic resonance imaging was used to determine LL and PM CSA. There were correlations between hip flexion power, sprint performance, and PM CSA, but LL showed no correlation with any parameter The impact of hip flexion power and LL on sprint stride pattern efficiency was considered. Hip flexion might not have a simple role in the passive knee replacement of the stride pattern; instead, it may be an active parameter. Other investigations are needed to determine the influence of pelvic architecture on sprint performance.  相似文献
