Sensitivity of whole wood stable carbon and oxygen isotope values to milling procedures

2014

RATIONALE Milling of wood samples is a widely applied preparation method for pooling tree-rings from different trees or periods of several years for determination of δ13C and δ18O values. In this study, whole wood samples were milled using different procedures in order to evaluate potential effects of this preparation method on δ13C and δ18O values. METHODS Subsamples of a 5 cm3 wood piece of a single tree-ring from a lowland white fir were used. The samples were milled with different setups: (i) two and three stainless-steel balls, (ii) 3, 5 and 8 min milling time, and (iii) discontinuous and continuous milling. The δ13C values were measured using an elemental analyser connected to an IsoP…

Evolution et structure des compétences des élèves à l'école élémentaire et au collège : une analyse empirique des évaluations nationales

2006

Il s'agit de la synthèse du rapport final en réponse à l'appel d'offres : Maîtrise du langage, diversité des pratiques pédagogiques et socle commun de compétences, pour le Centre Henri Aigueperse, UNSA-Education. La recherche, basée en grande partie sur l'analyse des résultats des élèves aux évaluations nationales, a pour objectif principal de mieux comprendre comment les acquisitions scolaires se structurent dans une double perspective : transversale (à un moment donné de la scolarité) et longitudinale (au cours des cycles d'enseignement). Dans cette optique, des données ont été collectées sur un échantillon d'environ 700 élèves originaires d'une même circonscription scolaire à différents …

Análisis de la adecuación de libros de texto de E. Primaria a la enseñanza a estudiantes de altas capacidades matemáticas

2013

Un problema al que se enfrentan los profesores de matemáticas de Enseñanza Primaria es la necesidad de hacer adaptaciones en sus programaciones para ofrecer una educación adecuada a sus alumnos de altas capacidades matemáticas. Las editoriales de libros de texto de matemáticas de estos niveles educativos ofrecen diversas soluciones que, usualmente, consisten en incluir, en el libro del alumno, algunos problemas más difíciles y, en la documentación del profesor, una propuesta de problemas de ampliación. Una cuestión que se plantea al analizar un libro de texto de matemáticas es valorar cómo de útil puede ser el material proporcionado por la editorial (libro de texto y materiales complementar…

Soil Science Challenges in a New Era: A Transdisciplinary Overview of Relevant Topics

2020

Transdisciplinary approaches that provide holistic views are essential to properly understand soil processes and the importance of soil to society and will be crucial in the future to integrate distinct disciplines into soil studies. A myriad of challenges faces soil science at the beginning of the 2020s. The main aim of this overview is to assess past achievements and current challenges regarding soil threats such as ero-sion and soil contamination related to different United Nations sustainable development goals (SDGs) including (1) sustainable food production, (2) ensure healthy lives and reduce environmental risks (SDG3), (3) ensure water availability (SDG6), and (4) enhanced soil carbo…

English and French Modes of Regulation of the Education System : a comparison

2003

03069; International audience; This paper describes English and French modes of regulation of the educational system, stressing the contrast between them (regulation by process versus regulation by outcomes), while their goals and organisation prove rather more convergent over the last 30 years. It tries to assess the correspondence between those two ways of operating and what we know about the functioning of organisations like schools. From that point of view, the French system fits the economic theory of organisation less well than the English one, so that some contradictions and tensions are predictable. Last, it looks for some relationhip with indicators of effectiveness, equity and soc…

Evaluation économique de la prématurité : une première année de vie aux enjeux majeurs : le cas de la France

2016

This thesis focuses on a first economic assessment of prematurity in France. Prematurity is defined as occurring before 37 weeks of gestation. It is increasing in France and worldwide. If the issues of public health are already well identified, medical care and collective choices concerning prematurity matters also involve significant economic challenges. The first part of this thesis attempts to present the public health issues of prematurity and highlights the remaining efforts required to provide prevention in France. It then considers economic issues on the use of socially fairer resources dedicated to perinatal health in a context where current health expenditure is rising. Assessment …

Forecasting Training Needs in the Hotel, Catering and Tourism Sector : A Comparative Analysis of Results from Regional Studies in Three European Coun…

2001

International audience; The European Union's recent LABOURatory project on "Regular Forecasting of Training Needs" was intended to explore labour-market information systems and methods in four EU Member States (France, Germany, Ireland and the Netherlands) and to compare them with data availability and applicable methods in three candidate countries (Czech Republic, Poland and Slovenia). The ultimate goal of the project, which was carried out under the Leonardo da Vinci programme, was the elaboration of a methodology for forecasting training needs that would be applicable in the context of labour markets in transition economies, as well as the improvement of existing prognostic approaches i…
