The role of sociales identities in the social representation of the fatigue in France and Syrie

2015

For a few years, many factors, such as the burden of training, are considered to be linked to the athletes’ difficulties to get used to training. The fatigue is one of the perceived problems by the athletes. Physiologically, the fatigue can be defined as “the decrease of a muscle’s capacity over time to exert force or power during a given exercise”. However, from the social point of view, the interpretation of fatigue is different and varies according to the social groups. This representation of the fatigue, specific to each group, should be considered as “a form of knowledge, socially developed and shared. In this doctoral thesis, we focus on the representation of fatigue in France and in …

A Neurocomputational Approach to Trained and Transitive Relations in Equivalence Classes

2017

A stimulus class can be composed of perceptually different but functionally equivalent stimuli. The relations between the stimuli that are grouped in a class can be learned or derived from other stimulus relations. If stimulus A is equivalent to B, and B is equivalent to C, then the equivalence between A and C can be derived without explicit training. In this work we propose, with a neurocomputational model, a basic learning mechanism for the formation of equivalence. We also describe how the relatedness between the members of an equivalence class is developed for both trained and derived stimulus relations. Three classic studies on stimulus equivalence are simulated covering typical and at…

Qualitative and Quantitative Study on Videotaped Data for Fire Emergency Response

2016

During search and rescue (SAR) operations, information plays a significant role in empowering the emergency response personnel at various levels. But, understanding the information which is being shared between/among emergency personnel is necessary to improve current coordination systems. However, such systems can help the first responders to gain/increase their situational awareness and coordination. Moreover, there is still the lack of automatic and intelligent tools that can contribute to structure, categorize, and visualize the communicated content that occur during SAR operations. Therefore, in this paper, we present the concept of such analysis by using the qualitative methodology an…

Disciplines and thematics of scientific research in police training (1988-2012)

2014

Purpose – The purpose of this paper is to analyze the disciplines and thematic study of scientific production in police training over the period 1988-2012. Design/methodology/approach – Introduction and homogenization of keywords and assigning of descriptors to documents, thematic categorization of journals and, analysis of indicators of productivity and relationship of descriptors and thematic areas has been the used methodology. Findings – Totally, 59 different descriptors of a total of 585 assigned to the 182 articles that were published in 95 journals belonging into 20 different subject areas have been identified. The most frequent descriptors are “skills,” “management development” and…

When the smile is a cue to familiarity

2000

International audience; The question discussed in the two following experiments concerns the effect of facial expressions on face recognition. Famous and unknown faces with neutral or smiling expression were presented for different inspection durations (15 ms vs 1000 ms). Subjects had to categorize these faces as famous or unknown (Experiment 1), or estimate their degree of familiarity on a rating scale (Experiment 2). Results showed that the smile increased ratings of familiarity for unfamiliar faces (Experiments 1 and 2) and for famous faces (Experiment 2). These data are discussed in the framework of current face-recognition models and are interpreted in terms of social value of the smil…

A method to optimize a typology-based classification system

2014

This study sought to provide guidelines for implementing typology-based qualitative analysis of human movement patterns.Fifteen participant-analysts were instructed how to classify treading water behaviours into eight different categories using a training set of videos. They were later provided with two additional sets of videos called validation, and test sets. Results first identified reliable (n=9), and not reliable (n=6) analysts. A decision study outlined that one analyst was sufficient to reliably categorize the behaviours in the ‘reliable’ analyst group, whereas up to four were necessary in the ‘unreliable’ group. These data provided new insights into more objective qualitative analy…

A novel active contour model for unsupervised low-key image segmentation

2013

Published version of an article in the journal: Central European Journal of Engineering. Also available from the publisher at: http://dx.doi.org/10.2478/s13531-012-0050-0 Unsupervised image segmentation is greatly useful in many vision-based applications. In this paper, we aim at the unsupervised low-key image segmentation. In low-key images, dark tone dominates the background, and gray level distribution of the foreground is heterogeneous. They widely exist in the areas of space exploration, machine vision, medical imaging, etc. In our algorithm, a novel active contour model with the probability density function of gamma distribution is proposed. The flexible gamma distribution gives a bet…

The discursive legitimation strategies of a nascent market

2017

Since the introduction of Gold&Green Foods Ltd’s Pulled Oats (Nyhtökaura) to the Finnish market in the spring 2016, the Finnish media has been increasingly reviewing different plant-based protein products. Gold&Green Ltd’s Pulled Oats has experienced extensive media coverage amongst other Finnish plant-based protein products which have been launched during 2016 such as VersoFood Ltd’s Härkis, Viipurilainen Kotileipomo’s Puhtikaura etc. It has yet to be seen whether the sudden inception of several plant-based protein product innovations will be defined as a pivotal era in the Finnish food industry or just a passing trend. Finnish media has aldo categorized MiFu as one of the up and coming fo…

Do categorical representations modulate early automatic visual processing? A visual mismatch-negativity study.

2021

Perceptual categorization is an important cognitive function. In the auditory domain, categorization already occurs within the first 200 ms of information processing, as indexed by the mismatch negativity. Here, we assessed the characteristics of the visual mismatch negativity (vMMN) elicited during the categorization of previously unknown visual stimuli. To examine this, we used five-dot patterns with characteristics that allow for the formation of categories through rotation and reflection but not through other physical properties. To assess whether or not between-category and within-category vMMN differ in amplitude, the data was analyzed with the Bayesian approach. We observed that both…
