Concepts, principes et outils de la méthodes Catalyse.

2005

Initially conceived in 1989, CATALYSE method of territorial intelligence is since 1994 the object of applications in about twenty regions of Europe. Its evolution is one research object of the European Network of Territorial Intelligence (ENTI/REIT). The communication exposes the fundamental concepts of the territorial intelligence. It clarifies the methodological - ethical and technological - principles which structure CATALYSE. It details tools proposed to the territorial actors of the sustainable development

Spoken Language Development and the Challenge of Skill Integration

2019

The development of phonological awareness, the knowledge of the structural combinatoriality of a language, has been widely investigated in relation to reading (dis)ability across languages. However, the extent to which knowledge of phonemic units may interact with spoken language organization in (transparent) alphabetical languages has hardly been investigated. The present study examined whether phonemic awareness correlates with coarticulation degree, commonly used as a metric for estimating the size of children's production units. A speech production task was designed to test for developmental differences in intra-syllabic coarticulation degree in 41 German children from 4 to 7 years of a…

Test methodologies for the unitary root

1998

This paper provides a critical survey on unit root testing procedures frequently used in empirical literature. The importance of the hypothesis of linearity of the deterministic component is stressed because its misspecification may result in the false conclusion that the time series has a unit root. Testing strategies elaborated by Dickey, Bell and Miller (1986), Perron (1988) and Dolado, Jenkinson and Sosvilla-Rivero (1990) are compared and their limit is evaluated. An empirical testing strategy is then proposed and applied to the analysis of the nonstationarity exhibited by real GDP in France. We show that it is possible to find some flexible specifications that enable us to reject the u…

Structure and determinants of production in Textile-Clothing-Leather-Skins (TCLS) craft industry in Benin: a study based on investigations of the val…

Lieu et date de la conférence modifiées. Prétoria 31Juillet au 2 Août 2014 (Au lieu de Kigali -Rwanda); International audience; Sustainable economic growth in Benin requires a better understand of the informalsector, which contributes to two-thirds of GDP. Particularly, craft industry and TCLSsubsector is one of informal activity sector to be handled. The objectives of this work wereto identify the structure and factors that determine the production in TCLS craft industry.This study was based on a survey carried out in February 2011 on value creationdata in craft industry of TCLS in Benin. Lack of data induced by informal activities wascircumvented using an imputation method. A Multiple Cor…

Can we ascertain that an archeological site contains intentional stellar alignments?

2021

We study the different parameters that support the presence of intentional stellar alignments on an archaeological site. We develop a rigorous criterion to quantify the probability of fortuitous orientation on a starrise or a starset. We show that the magnitude of the considered stars and the precision of the angular measurements are the two preponderant parameters. Our study aims at establishing the basis of reliable methods for archaeoastronomy.

Analítica o evocadora: el debate olvidado de la autoetnografía

2016

Existe la necesidad de una estrategia metodológica eficaz para sostener la investigación sobre la práctica profesional de los servicios sociales. La oposición entre el trabajo autoetnográfico de Carolyn ELLIS y Arthur BOCHNER (2000, 2006) y la propuesta analítica de Leon ANDERSON sirven como una lente a través de la cual explorar los aspectos clave de esta discusión. Mientras ELLIS y BOCHNER rechazan cualquier intento de abstracción o sistematización teórica, ANDERSON pretende tender puentes entre la tradición etnográfica y las formas emergentes de narrativa personal. Después de revisar la literatura autoetnográfica, concluyo que si bien la autoetnografía evocadora parece gozar del apoyo ma…

Comparison between simulated and observed LHC beam backgrounds in the ATLAS experiment at E beam =4 TeV

2018

Results of dedicated Monte Carlo simulations of beam-induced background (BIB) in the ATLAS experiment at the Large Hadron Collider (LHC) are presented and compared with data recorded in 2012. During normal physics operation this background arises mainly from scattering of the 4 TeV protons on residual gas in the beam pipe. Methods of reconstructing the BIB signals in the ATLAS detector, developed and implemented in the simulation chain based on the FLUKA Monte Carlo simulation package, are described. The interaction rates are determined from the residual gas pressure distribution in the LHC ring in order to set an absolute scale on the predicted rates of BIB so that they can be compared qua…
