L’appropriation territoriale des nouvelles gares TGV périphériques françaises au miroir des SCOT (Schéma de Cohérence Territoriale)
2019
International audience; Face à la grande diversité des dynamiques territoriales liées à la grande vitesse ferroviaire et aux difficultés rencontrées pour isoler l’influence de la nouvelle offre de transport des autres facteurs intervenant dans les évolutions socio-économiques et spatiales des territoires, les chercheurs s’attachent désormais davantage à la compréhension des processus par lesquels naissent les changements territoriaux en questionnant la façon dont les acteurs territoriaux s’approprient à travers leurs comportements, leurs pratiques et leurs représentations, la nouvelle offre de transport. Comme l’ont montré de nombreux travaux, l’infrastructure et les nouvelles conditions d’…
Emerging Economies’ Institutional Quality and International Competitiveness: A PLS-SEM Approach
2021
The home country’s institutional framework determines the capacity to compete in the global arena. This paper discusses the linkage between institutional quality (IQ) and international competitiveness (IC). We measured institutions’ quality in emerging economies through the use of selected indicators between 2007–2017. To evaluate the proposed IQ constructs and their relationship with IC, we applied partial least squares – structural equation modeling (PLS-SEM) analysis. The model outcomes suggest that political and lack of systemic conditions have a significant and negative effect on international competitiveness, while science, technology, engineering and mathematics (STEM) resource condi…
Multivariate versus univariate calibration for nonlinear chemiluminescence data
2001
Abstract Multivariate calibration is tested as an alternative to model chromium(III) concentration versus chemiluminescence registers obtained from luminol-hydrogen peroxide reaction. The multivariate calibration approaches included have been: conventional linear methods (principal component regression (PCR) and partial least squares (PLS)), nonlinear methods (nonlinear variants and variants of locally weighted regression) and linear methods combined with variable selection performed in the original or in the transformed data (stepwise multiple linear regression procedure). Both the direct and inverse univariate approaches have been also tested. The use of a double logarithmic transformatio…
Weighted-average least squares estimation of generalized linear models
2018
The weighted-average least squares (WALS) approach, introduced by Magnus et al. (2010) in the context of Gaussian linear models, has been shown to enjoy important advantages over other strictly Bayesian and strictly frequentist model averaging estimators when accounting for problems of uncertainty in the choice of the regressors. In this paper we extend the WALS approach to deal with uncertainty about the specification of the linear predictor in the wider class of generalized linear models (GLMs). We study the large-sample properties of the WALS estimator for GLMs under a local misspecification framework that allows the development of asymptotic model averaging theory. We also investigate t…
Genetic diversity and trait genomic prediction in a pea diversity panel
2014
Background Pea (Pisum sativum L.), a major pulse crop grown for its protein-rich seeds, is an important component of agroecological cropping systems in diverse regions of the world. New breeding challenges imposed by global climate change and new regulations urge pea breeders to undertake more efficient methods of selection and better take advantage of the large genetic diversity present in the Pisum sativum genepool. Diversity studies conducted so far in pea used Simple Sequence Repeat (SSR) and Retrotransposon Based Insertion Polymorphism (RBIP) markers. Recently, SNP marker panels have been developed that will be useful for genetic diversity assessment and marker-assisted selection. Resu…
A framework for remission in SLE
2017
ObjectivesTreat-to-target recommendations have identified ‘remission’ as a target in systemic lupus erythematosus (SLE), but recognise that there is no universally accepted definition for this. Therefore, we initiated a process to achieve consensus on potential definitions for remission in SLE.MethodsAn international task force of 60 specialists and patient representatives participated in preparatory exercises, a face-to-face meeting and follow-up electronic voting. The level for agreement was set at 90%.ResultsThe task force agreed on eight key statements regarding remission in SLE and three principles to guide the further development of remission definitions:1. Definitions of remission wi…
Retroposon insertions provide insights into deep lagomorph evolution.
2010
The homogenous mammalian order Lagomorpha comprises about 80 species in two families, Ochotonidae (pikas) and Leporidae (rabbits and hares). However, the phylogenetic relationships among leporids are controversial. Molecular data, particularly from mitochondrial sequences, give highly homoplasious signals. To resolve the controversy between mitochondrial and nuclear data, we analyzed genomic orthologous retroposon insertion sites, a virtually homoplasy-free marker system. From a differential screen of rabbit genomic data for intronic retroposon insertions of CSINE elements, we polymerase chain reaction-amplified and sequenced 11 retroposons in eight representative lagomorphs. We found three…
Redox regulation of genome stability by effects on gene expression, epigenetic pathways and DNA damage/repair
2015
Reactive oxygen and nitrogen species (e.g. H2O2, nitric oxide) confer redox regulation of essential cellular signaling pathways such as cell differentiation, proliferation, migration and apoptosis. In addition, classical regulation of gene expression or activity, including gene transcription to RNA followed by translation to the protein level, by transcription factors (e.g. NF-κB, HIF-1α) and mRNA binding proteins (e.g. GAPDH, HuR) is subject to redox regulation. This review will give an update of recent discoveries in this field, and specifically highlight the impact of reactive oxygen and nitrogen species on DNA repair systems that contribute to genomic stability. Emphasis will be placed …
Las estructuras de tierra delimitadas por zanjas en la Amazonía Occidental
2016
Esta tesis doctoral aborda el estudio de los sitios arqueológicos de la Amazonía Sur Occidental: Las estructuras de tierra delimitadas por zanjas. El descubrimiento de estos yacimientos dio, y sigue dando, una nueva realidad en la arqueología brasileña y de la Amazonía Occidental. Actualmente fueron hallados centenares de yacimientos (más de ochocientos) en los suelo descampados de la región y estos yacimientos son caracterizados como estructuras arqueológicas construidas mediante zanjas continuas, formando estructuras que delimitan espacios de diferentes formatos geométricos presentando una gran variedad de tamaños, que fueron construidos por poblaciones que vivieran en esta región de la A…
Spatial analysis of the relationship between mortality from cardiovascular and cerebrovascular disease and drinking water hardness
2004
Journal Article; Research Support, Non-U.S. Gov't; Reproduced with permission from Environmental Health Perspectives. Previously published scientific papers have reported a negative correlation between drinking water hardness and cardiovascular mortality. Some ecologic and case-control studies suggest the protective effect of calcium and magnesium concentration in drinking water. In this article we present an analysis of this protective relationship in 538 municipalities of Comunidad Valenciana (Spain) from 1991-1998. We used the Spanish version of the Rapid Inquiry Facility (RIF) developed under the European Environment and Health Information System (EUROHEIS) research project. The strateg…
