Showing the Invisible: The Economic Cycle of Stone Tools
2023
This contribution takes place in a broader theme, that of “the invisible economy of recyclable materials”. It aims to illustrate the phenomena of recovery of materials from lithic tools and their consequences. The classification of tools by material, although classic, is not relevant from a technical point of view. The material of a tool, in particular its mechanical properties, is to be taken into consideration in its technical analysis, but it cannot constitute a determining criterion in a classification system. Function should come first, as most functional categories use multiple materials. The most striking example, if one can say so, is that of the striking supports, where one finds, …
Conception of a territorial observation and prospective tool for energy. The case of fuelwood.
2008
International audience; Decentralized energy planning has been emerged in France since the last three decades especially due to the development of renewable energies. One corollary is the increase of local actors' role in energy and land planning. In order to help them carrying out efficient policies, decision support systems (DSS) have been developed. In this paper, the authors deal with a DSS applied to fuelwood sector.
Geostatistical computing of acoustic maps in the presence of barriers
2009
Acoustic maps are the main diagnostic tools used by authorities for addressing the growing problem of urban acoustic contamination. Geostatistics models phenomena with spatial variation, but restricted to homogeneous prediction regions. The presence of barriers such as buildings introduces discontinuities in prediction areas. In this paper we investigate how to incorporate information of a geographical nature into the process of geostatistical prediction. In addition, we study the use of a Cost-Based distance to quantify the correlation between locations.
The Corpus of Advanced Learner Finnish (LAS2): Database and toolkit to study academic learner Finnish
2014
This paper introduces the Corpus of Advanced Learner Finnish (LAS2), one of the existing corpora of learner Finnish. The corpus was started at the University of Turku in 2007, and the initial motivation for its collection was to make it possible to deal with novel linguistic challenges posed by academic immigration and to contribute to corpus linguistics, Finnish linguistics and the study of second language acquisition. This paper describes the typological standpoint of the LAS2, its position with respect to other corpora of learner Finnish, the compilation criteria, the annotation applied and the workflow implemented. The corpus consists of three subcorpora of written academic texts of non…
Diagnostic Tools for Autism Spectrum Disorders by Gender: Analysis of Current Status and Future Lines
2021
Studies on the prevalence of autism spectrum disorders have shown gender disproportion. In recent years, there has been an increasing interest in this investigation area. There are two main research lines; the first is focused mostly on gender-related biological reasons that could account for low ASD prevalence in women (i.e., related to some protective factors related to hormones or the immune system, among others), and the second research line studies possible diagnostic biases. In the present study, a review of the latter line of research is made based on two main objectives: (a) analysis of possible biases in diagnostic tools and (b) other nonbiological ASD prevalence explained by gende…
Tasks and Digital Tools
2016
International audience; This chapter considers scholastic tasks with digital tools. The first two sections consider tasks in ‘ordinary’ classrooms (tasks for learning) and issues relating to tasks using mathematical software. The first section presents examples of tasks with digital tools to highlight potential problems and opportunities for learning. The second section considers issues arising from the literature on tasks design with and without digital tools. The final section looks at task-tool issues in larger-than-the-individual classroom research and in assessment; it also comments of avenues for further development
Computer-assisted preparation in conference interpreting
2017
Preparation has been proposed in the literature as one of the most important phases of an interpreting assignment, especially if the subject is highly specialised. Preparing an assignment in advance aims at bridging the linguistic and extra-linguistic gap between conference participants and interpreters and at reducing the cognitive load during interpretation. For these reasons it is considered crucial in ensuring higher interpreting quality. Yet, preparation is generally time-consuming and interpreters may often experience the feeling of not knowing exactly how to perform this task efficiently. Information technology could change this. Even though the first computer-assisted interpreting s…
Bringing a Molecular Plus One : Synergistic Binding Creates Guest-Mediated Three-Component Complexes
2020
C-Ethyl-2-Methylresorcinarene (A), pyridine (B), and a set of ten carboxylic acids (Cn) associate to form A·B·Cn ternary assemblies with 1:1:1 stoichiometry, representing a useful class of ternary systems where the guest mediates complex formation between the host and a third component. Although individually weak in solution, the combined strength of the multiple non-covalent interactions organizes the complexes even in a highly hydrogen-bond competing methanol solution as explored by both experimental and computational methods. The interactions be-tween A·B and Cn are dependent on the pKa values of carboxylic acids. The weak interactions between A and C further reinforce the interactions b…
Biophysical approaches for the study of metal-protein interactions
2019
Protein-protein interactions play important roles for a variety of cell functions, often involving metal ions; in fact, metal-ion binding mediates and regulates the activity of a wide range of biomolecules. Enlightening all of the specific features of metal-protein and metal-mediated protein-protein interactions can be a very challenging task; a detailed knowledge of the thermodynamic and spectroscopic parameters and the structural changes of the protein is normally required. For this purpose, many experimental techniques are employed, embracing all fields of Analytical and Bioinorganic Chemistry. In addition, the use of peptide models, reproducing the primary sequence of the metal-binding …
Mathematics teachers and digital tools
2016
International audience; This chapter considers mathematics teachers’ appropriation and classroom use of digital tools. The first section considers teachers—who are they, how are they conceived in the literature and what aspects of teachers have been studied? The second section examines twenty-first century research on mathematics teachers using digital tools. This sheds light on the complexity of mathematics teachers’ appropriation and classroom use of digital tools but what we find is that our focus is too narrow and we need to consider digital tools within the range of resources use in planning and realising their lessons, which leads us to the third section, mathematics teachers using re…
