Experimental investigations of the hypernucleus $_Λ^4$H

2015

International audience; Negatively charged pions from two-body decays of stopped _Lambda^4H hypernuclei were studied in 2012 at the Mainz Microtron MAMI, Germany. The momenta of the decay-pions were measured with unprecedented precision by using high-resolution magnetic spectrometers. A challenge of the experiment was the tagging of kaons from associated K^+∧ production off a Be target at very forward angles. In the year 2014, this experiment was continued with a better control of the systematic uncertainties, with better suppression of coincident and random background, improved particle identification, and with higher luminosities. Another key point of the progress was the improvemen…

From a bodily-based format of knowledge to symbols. The evolution of human language

2013

Although ontogeny cannot recapitulate phylogeny, a two-level model of the acquisition of language will be here proposed and its implication for the evolution of the faculty of language will be discussed. It is here proposed that the identification of the cognitive requirements of language during ontogeny could help us in the task of identifying the phylogenetic achievements that concurred, at some point, to the acquisition of language during phylogeny. In this model speaking will be considered as a complex ability that arises in two different steps. The first step of competence widely relies on a bodily-based format of knowledge. The second step relies on more abstract meta-representations …

Language Detection and Tracking in Multilingual Documents Using Weak Estimators

2010

Published version of an article from the book: Structural, Syntactic, and Statistical Pattern Recognition . The original publication is available at Spingerlink. http://dx.doi.org/DOI: 10.1007/978-3-642-14980-1_59 This paper deals with the extremely complicated problem of language detection and tracking in real-life electronic (for example, in Word-of-Mouth (WoM)) applications, where various segments of the text are written in different languages. The difficulties in solving the problem are many-fold. First of all, the analyst has no knowledge of when one language stops and when the next starts. Further, the features which one uses for any one language (for example, the n-grams) will not be…

Embedded controlled language to facilitate information extraction from eGov policies

2015

The goal of this paper is to propose a system that can extract formal semantic knowledge representation from natural language eGov policies. We present an architecture that allows for extracting Controlled Natural Language (CNL) statements from heterogeneous natural language texts with the ability to support multilinguality. The approach is based on the concept of embedded CNLs.

THE USE OF WEAK ESTIMATORS TO ACHIEVE LANGUAGE DETECTION AND TRACKING IN MULTILINGUAL DOCUMENTS

2013

This paper deals with the problems of language detection and tracking in multilingual online short word-of-mouth (WoM) discussions. This problem is particularly unusual and difficult from a pattern recognition perspective because, in these discussions, the participants and content involve the opinions of users from all over the world. The nature of these discussions, consisting of multiple topics in different languages, presents us with a problem of finding training and classification strategies when the class-conditional distributions are nonstationary. The difficulties in solving the problem are many-fold. First of all, the analyst has no knowledge of when one language stops and when the…

An extended version of the theory of planned behavour: Prediction of intentions to quit smoking using past behaviour as moderator

2010

It was hypothesised that: (i) intentions to quit smoking were predictable from group identity, self-identity, moral norms and past quit attempts, beyond the components of the Theory of Planned Behaviour (TPB), and (ii) that past experiences with the behaviour (quit attempts) would increase the predictive utility of the extended TPB model on intentions. The data was collected among 357 daily smoking students (M = 24 years). The TPB components accounted for 12.3% of the variance in quitting intentions, while the extension variables added 16.5% to the explained variance in intentions beyond the impact of the TPB. Past behaviour had the strongest impact on intentions (α = 0.30), followed by mor…

Stereotype threat and lift effects on perceived ability and motor task performance of high school physical education students: the moderating role of…

2016

This study investigated the effects of stereotype threat and lift on perceived ability and motor task performance, and tested the moderating effects of stereotype endorsement and domain identification. One hundred and twenty French high school students were randomly assigned to control, stereotype threat, or stereotype lift conditions, in a 3 (condition) × 2 (sex) study design. The results revealed a stereotype lift effect on boys’ performance moderated by domain identification and a stereotype threat effect on girls’ perceived ability moderated by domain identification and stereotype endorsement. Perceived ability did not mediate the effects of stereotype threat and lift on performance. Th…

Discovering prominence and its role in language processing: an individual (differences) approach

2015

Abstract It has been suggested that, during real time language comprehension, the human language processing system attempts to identify the argument primarily responsible for the state of affairs (the “actor”) as quickly and unambiguously as possible. However, previous work on a prominence (e.g. animacy, definiteness, case marking) based heuristic for actor identification has suffered from underspecification of the relationship between different cue hierarchies. Qualitative work has yielded a partial ordering of many features (e.g. MacWhinney et al. 1984), but a precise quantification has remained elusive due to difficulties in exploring the full feature space in a particular language. Feat…

Idiomatic intonation and forensic phonetics: sociolinguistic and dialectal information from intonation in Spanish

2015

Las investigaciones de carácter geoprosódico realizadas sobre el español y sus variedades ponen en evidencia que la entonación puede reportar importantes beneficios a la fonética forense, ya que esta lleva asociada información de carácter dialectal y sociolingüístico de especial relevancia sobre el individuo –grupo sociocultural al que pertenece, origen geográfico, medio social en el que se inserta–, además de otros rasgos, cualidades o circunstancias como la edad, el sexo, o incluso su temperamento, carácter o estado de ánimo. Para ello se hace necesario no solo saber qué parámetros acústicos suprasegmentales son relevantes para la identificación del hablante, sino también analizar la vari…
