La motivation des étudiants à l’entrée à l’université : quels effets directs ou indirects sur la réussite ?
2015
L’enjeu de cet article réside dans la mesure du rôle des capacités motivationnelles des étudiants sur la réussite universitaire, en adoptant une démarche quantitative et intégrative. À cette fin, les données récoltées sur des étudiants en première année de licence de trois filières permettent de contrôler un ensemble de facteurs relatifs aux caractéristiques socio-démographiques et scolaires des étudiants. Mesurée dans le cadre de la théorie de l’autodétermination, il ressort des analyses que la motivation intrinsèque exerce une influence positive tandis que l’amotivation se traduit par de moins bonnes performances. Par ailleurs, la motivation est un atout pour les bons étudiants, mais ne j…
Effects of texture and temperature on the kinetic of aroma release from model dairy custards
2010
http://www.sciencedirect.com/science/article/B6T6R-4YYRMXD-2/2/9ac9167b05d21ef9ff6dcce684696e13 http://www.elsevier.com/locate/foodchem; International audience; The structure of a foodstuff, and its perceived texture, are important characteristics involved in the sensory availability of flavour compounds released during the food consumption. This study identifies the effect of texture on the dynamic release of aroma compounds under simulated oral conditions (temperature and shearing). Two custard desserts, with two levels of texture but the same composition, flavoured with four aroma compounds, were analysed. The rheological behaviour of the custards and the release of aroma compounds (SPME…
Experiences from a wearable-mobile acquisition system for ambulatory assessment of diet and activity
2017
Public health trends are currently monitored and diagnosed based on large studies that often rely on pen-and-paper data methods that tend to require a large collection campaign. With the pervasiveness of smart-phones and -watches throughout the general population, we argue in this paper that such devices and their built-in sensors can be used to capture such data more accurately with less of an effort. We present a system that targets a pan-European and harmonised architecture, using smartphones and wrist-worn activity loggers to enable the collection of data to estimate sedentary behavior and physical activity, plus the consumption of sugar-sweetened beverages. We report on a unified pilot…
T-pattern analysis for the study of temporal structure of animal and human behavior : a comprehensive review
2014
A basic tenet in the realm of modern behavioral sciences is that behavior consists of patterns in time. For this reason, investigations of behavior deal with sequences that are not easily perceivable by the unaided observer. This problem calls for improved means of detection, data handling and analysis. This review focuses on the analysis of the temporal structure of behavior carried out by means of a multivariate approach known as T-pattern analysis. Using this technique, recurring sequences of behavioral events, usually hard to detect, can be unveiled and carefully described. T-pattern analysis has been successfully applied in the study of various aspects of human or animal behavior such …
Under my wing: lesser kestrels and jackdaws derive reciprocal benefits in mixed-species colonies
2011
In mixed-species assemblages, antipredator benefits for a timid species nesting close to a more pugnacious one are often reported. Advantages for the protected species are usually manifested in terms of higher reproductive success than conspecifics nesting remote to the protector species. Whether the protector species also accrues any benefit remains untested, and the species-specific behavioral traits underlying enhanced reproductive output in mixed-species associations remain poorly documented. We studied associations between lesser kestrels (Falco naumanni) and jackdaws (Corvus monedula) nesting in rural buildings in the Gela Plain (Italy). We tested for interspecific interactions of jac…
Theory-based digital intervention to promote weight loss and weight loss maintenance (Choosing Health)
2020
IntroductionDigital behavioural weight loss interventions have the potential to improve public health; however, these interventions are often not adequately tailored to the needs of the participants. This is the protocol for a trial that aims to determine the effectiveness and cost-effectiveness of the Choosing Health programme as a means to promote weight loss and weight loss maintenance among overweight/obese adults.Methods and analysisThe proposed study is a two-group randomised controlled trial with a nested interrupted time series (ITS) within-person design. Participants (n=285) will be randomly assigned to either the Choosing Health digital intervention or a control group. For interve…
Preliminary study of coach verbal behaviour according to game actions
2012
Guzman JF, Calpe-Gomez V. Preliminary study of coach verbal behaviour according to game actions. J. Hum. Sport Exerc. Vol. 7, No. 2, pp. 376-382, 2012. The aim of this study was to analyse the interaction between game actions in high-level handball and verbal behaviour performed by the coach. For this purpose, a match of the 1 st National Division of male Spanish handball was analysed. The type of behaviour and the content of the message reported by the coach were recorded using a modified version of Coaching Behaviour Assessment System (CBAS) and Coach Analysis and Intervention System (CAIS). About game actions, they were grouped into positive and negative. Statistically significant differ…
Photo-oxidation behaviour of polyethylene/polyamide 6 blends filled with organomodified clay: Improvement of the photo-resistance through morphology …
2010
Abstract The impact of small amounts of organomodified clay (OMMT) on the photo-degradation behaviour of two blends obtained by mixing either low-density polyethylene (LDPE) or high density polyethylene (HDPE) with polyamide 6 (PA6) (LDPE/PA6 and HDPE/PA6 75/25 wt-%) was studied. The complex photo-degradation behaviour was followed by monitoring the main physical–mechanical properties of the blends. In particular, mechanical and spectroscopic tests were performed in conditions of accelerated artificial aging. An accurate mechanical and morphological characterization was previously carried out. The presence of the OMMT promotes the unexpected formation of a co-continuous morphology for the H…
