Unite against: A common threat invokes spontaneous decategorization between social categories
2019
Abstract A frequent rhetoric in the political arena calls members of larger groups like nations to lay aside all dividing differences and unite in face of a common threat. In the present research we sought to test whether such a unifying effect of external threat already manifests in such basic cognitive processes as automatic categorization even for such strong schisms as the ones between black and white Americans or Israeli Jews and Arabs. In Studies 1 & 2 (N = 183/144, USA), we established the decategorization effect in the context of black and white US Americans. In Study 3, we showed the effect again in a German lab for the gender category (N = 101). In Study 4 (N = 168, Israel), we tr…
Conceptual vs. perceptual wine spaces: Does expertise matter?
2008
Abstract This study explores the differences in wine categorization between wine experts and novice wine consumers using 10 Melon de Bourgogne (MB) and 10 Chardonnay (CH) wines. Participants performed a free sorting task based on odor similarity followed by a CH and a MB typicality rating task and a liking rating. All tasks were performed orthonasally. We observed a clear agreement between experts concerning typicality scores. Moreover, despite a slight overlap we found a clear differentiation between CH and MB for experts’ typicality scores. For novices, no such agreement on typicality scores was observed and we found a complete overlap between both types of wines. These results suggest th…
Exemplarity measurement and estimation of the level of interjudge agreement for two categories of French red wines
2015
Abstract Exemplarity measurements of wines by at least 20 judges are used to estimate the degree of interjudge (dis)agreement and to tell wines apart into two contrasting extremes. Two sets of French red wines – Pinot noir from Burgundy and Cabernet franc from the Loire Valley – are studied separately but by the same approach. Short-listing criteria are used to collate 40 starting-price and middle-range wines for each set differing a priori in olfactory terms. Wine professionals assess their local wines first orthonasally and then, independently, by global evaluation. A pool of descriptive and inferential statistics indicates there is generally neither complete divergence nor real agreement…
Wine list engineering: categorization of food and beverage outlets
2009
PurposeThe purpose of the paper is to identify and measure the main standards of the wine lists of upscale restaurants.Design/methodology/approachWine lists of a sample of 50 upscale restaurants were analyzed. A cluster analysis was performed.FindingsThree differentiated profiles of restaurants are identified according to their wine list management: selection, specialization and complementarity.Research limitations/implicationsThis study was exploratory and similar studies need to be performed covering more geographic locations.Practical implicationsRestaurants differ in their current practices and key standards of their wine lists according to their positioning strategy. Upscale restaurant…
Extrinsic attributes responsible for red wine quality perception: A cross-cultural study between France and Spain
2014
Understanding quality perception requires focusing both on product proprieties and consumers' representations. The goal of this study was to access the representations of perceived extrinsic wine quality of consumers from two different wine regions in two European countries with an important wine tradition: La Rioja-RJ-(Spain) and Cotes du Rhone-CdR-(France). Twenty commercial red wines (ten from RJ and ten from CdR) were evaluated in terms of quality by means of a categorization task. Ninety-five French and 93 Spanish consumers had to categorize the 20 wines according to four levels of quality going from very low to very high quality. Three clusters of French and two of Spanish consumers h…
Socio Psychological Counseling: How to Manage Identities?
2013
The work presented here is a research carried out into initiatives for returning the long-term unemployed to work. A small case group study based on international expertise in social categorization and communication was conducted in France. This analysis of “long-term unemployment” was done through the consequences for relationships with work with a view to suggesting a suitable remedial approach. The recommended socio psychological counseling is based on reconstructing the professional identity of the long-term unemployed person and implementing this before the return to a supported role that should serve as a springboard towards permanent employment. The results lead to extend this method…
Quantitative studies of bird movement: a methodological review
1999
The past several years have seen the development of a number of statistical models and methods for drawing inferences about bird movement using data from marked individuals. It can be difficult to keep up with this rapid development of new methods, so our purpose here is to categorize and review methods for drawing inferences about avian movement. We also outline recommendations about future work, dealing both with methodological developments and with studies directed at hypotheses about bird movement of interest from conservation, management, or ecological perspectives.
Paratextual Prometheus. Digital Paratexts on YouTube, Vimeo and Prometheus Transmedia Campaign
2015
The object of this article is to map correspondences between the literacy of books and the literacy of online video platforms, in order to create common ground between both media and assist transmedia storytellers in the task of exploring video platforms with in-depth knowledge of each textual element surrounding video content. The article proposes a comprehensive categorization and typification of surrounding information in the standard video pages of YouTube and Vimeo, using Gerard Genette’s theory of paratexts as a basic framework. The analysis found that the interplay between paratextual elements, the audience feedback and the absence of endorsement from authors to paratexts created by …
An Image Segmentation Algorithm based on Community Detection
2016
International audience; With the recent advances in complex networks, image segmentation becomes one of the most appropriate application areas. In this context, we propose in this paper a new perspective of image segmentation by applying two efficient community detection algorithms. By considering regions as communities, these methods can give an over-segmented image that has many small regions. So, the proposed algorithms are improved to automatically merge those neighboring regions agglomerative to achieve the highest modularity/stability. To produce sizable regions and detect homogeneous communities, we use the combination of a feature based on the Histogram of Oriented Gradients of the …
Manufactured object sub-segmentation based on reflection motion estimation
2015
International audience; In computer vision, reflection is a long-standing problem, it covers image textures, makes original color difficult to recognize, complicates the understanding of the scene. Most of the time, it is considered as “noise”. Many methods are proposed in order to reduce or delete the reflection effects in the image, but generally, the performances are not quite satisfactory. While instead of working on “de-noising”, we propose a method to take advantage of moving reflections that can be used for different computer vision applications. For instance, the segmentation of reflective manufactured objects is presented in this paper. We focus on tracking reflection components an…
