Predicting domain-specific actions in expert table tennis players activates the semantic brain network.
2018
Motor expertise acquired during long-term training in sports enables top athletes to predict the outcomes of domain-specific actions better than nonexperts do. However, whether expert players encode actions, in addition to the concrete sensorimotor level, also at a more abstract, conceptual level, remains unclear. The present study manipulated the congruence between body kinematics and the subsequent ball trajectory in videos of an expert player performing table tennis serves. By using functional magnetic resonance imaging, the brain activity was evaluated in expert and nonexpert table tennis players during their predictions on the fate of the ball trajectory in congruent versus incongruent…
Global age-sex-specific fertility, mortality, healthy life expectancy (HALE), and population estimates in 204 countries and territories, 1950–2019: a…
2020
Background Accurate and up-to-date assessment of demographic metrics is crucial for understanding a wide range of social, economic, and public health issues that affect populations worldwide. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 produced updated and comprehensive demographic assessments of the key indicators of fertility, mortality, migration, and population for 204 countries and territories and selected subnational locations from 1950 to 2019. Methods 8078 country-years of vital registration and sample registration data, 938 surveys, 349 censuses, and 238 other sources were identified and used to estimate age-specific fertility. Spatiotemporal Gaussian…
Determinants of migratory flow in Europe: A fuzzy-set approach
2018
Abstract This article examines the variables that explain immigrants' decisions to remain in 18 European countries at three key stages of the European economic cycle: 2006 (economic boom), 2009 (the height of the economic and financial crisis), and 2014 (beginning of recovery). Population variables, environmental and health service variables, and economic variables were considered. Fuzzy-set qualitative comparative analysis (fsQCA) was used to conduct the analysis. The findings indicate that immigration behavior differs according to the stage of the economic cycle. When the economic cycle is in a favorable stage (boom and economic recovery), the GDP growth and land surface area of the recei…
Hyperchargeless triplet Majoron model.
1989
We study the general conditions to maintain the scale of the lepton-number-breaking vacuum expectation value at the electroweak scale. It is shown that the only possibilities are if the main component of the resulting Majoron is a hyperchargeless complex triplet or a neutral singlet. Models with a hyperchargeless triplet, even though phenomenologically more interesting, seem to be very difficult to build because they like to break charge conservation. However, we have found a particular extension, by adding an additional neutral singlet, that solves this problem. The model can give a Majorana mass to the neutrinos in the eV range, ..mu -->..e..gamma.. can proceed with branching ratios at th…
La fabrication des artisans : socialisation et processus de médiation dans l'apprentissage de la menuiserie
2012
This doctoral thesis in Communication Sciences offers to rethink the question of transmission of manual trades, in the context of contemporary craft industry in France. We analyse the classical dualism between “manual” and “nonmanual”, and go further with a theoretical approach of intelligence derived from Janet and Jousse. We also base our analysis on the studies about socialization, especially from Dubar, so we can involve a non-determinist model of transmitting manual crafts. In order to recognize the importance of working with materials, tools, in occupational socialization, we propose to look at its sequence as a “process of mediation” and to describe its communication device, inspired…

Long-term melodic expectation: The unexpected observation of distant priming effects
2009
The report provides a brief account of an experiment whose control conditions produced interestingly counter-intuitive results. The method adapted priming techniques to explore whether imagining well-known melodies would facilitate perceptual discrimination of congruent compared to incongruent melodic continuations in a syllable identification task. This was shown to be the case, but in a subsequent control experiment, imagining an irrelevant lure melody also showed a priming effect. The persistent priming effect apparently related the target sequence to the aurally presented, nonadjacent opening notes, and not to the intervening mental image. A number of statistical analyses of the pitch …
A Problem of Optimization in a Case of Foreign Investment
2000
The aim of the paper is to solve an optimization problem in an economic system with a central bank and a set of private agents. Each agent aims to maximize her expected utility, with rational expectations and being risk averse. The agents follow a profitability-risk criterium to face the portfolio diversification problem between foreign or domestic investment. An explicit formula for the optimal amount of foreign investment as a function of the expected exchange rate and an explicit formula for the exchange rate are obtained. These formulas show the hard influence of the expected exchange rate, the variance and the risk aversion on the agents’ decisions.
ECONOMIC EVALUATION OF AQUACULTURE INVESTMENTS UNDER CONDITIONS OF RISK AND UNCERTAINTY IN THE MEDITERRANEAN SEA
2014
This study aims to analyze, from a technical and ec onomic point of view, the choice between alternative investments in aquaculture under condit ions of risk and uncertainty. In particular, a comparative analysis has been conducted between an inshore and an offshore farm producing European sea bass in the Mediterranean Sea. The app lied model refers to the theory of subjective probability, assigning a different probability to e xpected incomes during the investment period. Resul ts show an economic convenience of inshore with respect to offshore farming.
