Arithmetic and aging: Impact of quantitative knowledge and processing speed

The main objective of this study was to examine how quantitative knowledge (Gq in the CHC model) and processing speed (Gs in the CHC model) affect scores on the WAIS-III Arithmetic Subtest (Wechsler, 2000) with aging. Two age groups were compared: 30 young adults and 25 elderly adults. For both age groups, Gq was an important predictor of Arithmetic score variance (R² = 48% and R² = 45%, respectively). However, in line with Salthouse, the results showed that processing speed predicted Arithmetic scores only for the older adults, not for the younger ones (additional 9% of the variance for the elderly vs. 1% of the variance for the young adults). These results can clarify the ambiguous evolution of Arithmetic scores with aging: Arithmetic performance with aging seems to follow an intermediate path between Gc and Gf. This suggests that both Gq and Gs have an impact on Arithmetic in aging.     

Expert Opinion and Gastronomy: The Recipe for Success

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.     

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

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.     

Test Reliability When Error Scores Consist of Independent and Non-Independent Components

To assess the effects of logical support, the Smith, Meux, Coombs, and Nuthall (12) system for the analysis of teaching strategies was used to construct four passages for each of two topics, fluoridation and the use of pesticides. The four passages varied in degree and kind of support or justification for the negative value judgments used. The passages were administered to 303 eleventh grade students. The group which received the passages having the most support for the negative value judgments reacted negatively as much or more than the other three groups, while the group which received the passages having the least support reacted negatively as little or less than the other three groups. There was also a topic-by-passage interaction.     

Chinese communication characteristics: A Yin Yang perspective

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.     

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

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.

Inference and evaluation of the multinomial mixture model for text clustering

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.     

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

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.
