Possession in Football: More Than a Quantitative Aspect – A Mixed Method Study
2019
The aim of the present study was to identify and differentiate the factors that determine the possession times of successful and unsuccessful elite football teams, with the purpose of identifying a more effective possession model. For this, match corresponding to the round of eighth-finals, quarter-finals, semi-finals and final of the 2016 UEFA Euro France in which 2,636 offensive sequences occurred, were analyzed. Video recordings of matches were analyzed and coded post-event using systematic observation. The performance indicators recorded and analyzed were: phase; match period; type of start-up; interaction context; intention; field zone; possession time, passes, attack outcome; match st…
Dix ans d'archéologie forestière dans le Châtillonnais (Côte-d'Or) : enclos, habitats, parcellaires
2010
National audience; Ces recherches sur les ensembles de structures de pierre sous forêt sont mises en œuvre depuis dix ans et sont inté- grées depuis 2003 dans le P.C.R. ‘Vix et son Environnement', dirigé par C. Mordant, S. Wirth et B. Chaume. Les vestiges étudiés sont implantés dans deux milieux géographiques distincts mais contigus : le plateau calcaire recouvert par la forêt domaniale de Châtillon, et les rebords de la Digeanne et du Brevon qui entaillent ce plateau à l'est et au sud. La prospection présente ici des caractères particuliers liés au couvert forestier. Les relevés G.P.S. sont intégrés dans un S.I.G. et constituent la base de cette étude, dans un va et vient…
Persistence in complex systems
2022
Persistence is an important characteristic of many complex systems in nature, related to how long the system remains at a certain state before changing to a different one. The study of complex systems' persistence involves different definitions and uses different techniques, depending on whether short-term or long-term persistence is considered. In this paper we discuss the most important definitions, concepts, methods, literature and latest results on persistence in complex systems. Firstly, the most used definitions of persistence in short-term and long-term cases are presented. The most relevant methods to characterize persistence are then discussed in both cases. A complete literature r…

Ursula Hicks and Vera Lutz’s Contributions to Development Finance
2018
International audience; This paper analyses the different approaches of two pioneering economists in the field of development finance, Ursula Kathleen Hicks (1896-1985) and Vera Constance Lutz (1912-1976). While research in economics in the 1950s focuses predominantly on finance in already developed countries (Goldsmith, 1969 and Gurley and Shaw, 1955), Hicks and Lutz extended the analysis to developing countries and/or regions – an original initiative for this period of time. Interested in the study of money and banking, Hicks and Lutz nevertheless had different beliefs on the way to promote economic development. This difference of thought comes from differing philosophical backgrounds.
Estimating finite mixtures of semi-Markov chains: an application to the segmentation of temporal sensory data
2019
Summary In food science, it is of great interest to obtain information about the temporal perception of aliments to create new products, to modify existing products or more generally to understand the mechanisms of perception. Temporal dominance of sensations is a technique to measure temporal perception which consists in choosing sequentially attributes describing a food product over tasting. This work introduces new statistical models based on finite mixtures of semi-Markov chains to describe data collected with the temporal dominance of sensations protocol, allowing different temporal perceptions for a same product within a population. The identifiability of the parameters of such mixtur…
The three wives problem and Shapley value
2015
We examine the Talmudic three wives problem, which is a generalization of the Talmudic contested garment problem solved by Aumann and Maschler (1985) using coalitional procedure. This problem has many practical applications. In an attempt to unify all Talmudic methods, Guiasu (2010, 2011) asserts that it can be explained in terms of “run-to-the-bank”, that is, of Shapley value in a “cumulative game”. It can be challenged because the coalitional procedure yields the same result as the nucleolus, which corresponds to a “dual game”. As Guiasu's solution is paradoxical (it has all the appearances of truth), my contribution consists in explaining the concepts, particularly truncation, that play …
“I feel many contradictory emotions” : Finnish mothers' discursive struggles with motherhood
2022
Objective The aim of the study was to facilitate the understanding and interpretation of multiple aspects of working with mothers by examining Finnish mothers' mothering discourses and the interplay among these discourses. Background According to relational dialectics theory, discourses are systems of meaning that are coproduced in interaction. Although discursive research on motherhood has identified various discourses, research on the interplay among competing motherhood discourses is in its infancy. Method Qualitative questionnaire data from 479 Finnish mothers of infants were analyzed using contrapuntal analysis. Mothers' responses to three open-ended questions were analyzed inductively…
Approaching the whole quality of buildings: methods for the evaluation of economic, energetic and environmental issues
2002
In this work the energy, economy and environment ("three E") requirements for buildings are approached in a joint view, by means of an application to an example building typical of the Italian building stock. With this aim, the rate of involvement of renewable sources is here considered for linking energy and environmental characteristics. Economic and environmental features are joint by means of the evaluation of the cost of the saved CO2. Economic and energy characteristics are linked by means of the cost of the saved energy. In turn, the environmental ambit is addressed by means of the ecoprofile methodology and of the environmental labelling of buildings. This should lead toward a first…
Esteroide anabolizanteak. Goi mailako kirol alorretik gimnasioetara
2013
El presente estudio pretende caracterizar sociológicamente el consumidor recreativo de esteroides anabolizantes en tierras valencianas. La investigación se desarrolla así a partir de la aplicación de una metodología explícitamente cualitativa y la puesta en práctica de la técnica de la entrevista semiestructurada. El perfil sociológico del consumidor recreativo de esteroides anabolizantes se caracteriza por un bajo nivel de estudios, cierta inestabilidad laboral vinculada a menudo con el mundo del ocio nocturno y de la seguridad tanto privada como pública, problemas familiares, gusto por las discotecas y la playa, y frecuentes rupturas en sus relaciones de pareja, entre otros aspectos. Se c…
