Generalizing novel names in comparison settings: Role of conceptual distance during learning and at test
2017
International audience; In a comparison setting (two stimuli), we tested 4- and 6-year-old children’s generalization of novel names for objects. We manipulated the semantic distance between the two learning items (e.g., two bracelets versus a bracelet and a watch), and the semantic distance between the learning items and the test items (e.g., a pendant versus a bow tie). We tested whether smaller semantic distance between learning items would lead to more taxonomic (vs. perceptual) choices at test, than broader semantic distance during learning, especially in the case of distant test stimuli. Results revealed main effects of learning distance, of generalization distance and that only childr…
ToToPI (Topographie de Tours Pré-Industriel), a GIS for understanding urban dynamics based on the OH_FET model (Social Use, Space and Time)
2009
http://proceedings.caaconference.org/files/2009/41_Rodier_et_al_CAA2009.pdf; International audience; ToToPI, for Topography of Tours Pre-Industrial, is a GIS for studying of the city of Tours (France) in large time span. The concepts for understanding the urban dynamic is based on considering the town as a set of complex objects, taking a systemic approach. The town system used to study the urban fabric over large time spans is composed of three sub-systems relating to historical objects from the level of the excavation to that of the former urban space: function (social use), space (location, surface area and morphology) and time (dating, duration and chronology). The historical object is …
On students' understanding of Riemann sums of integrals of functions of two variables
2018
International audience; APOS (Action-Process-Object-Schema) Theory is used to pose and test a conjecture of mental constructions that may be used to understand the relation between integrals of two variable functions over rectangles and corresponding Riemann sums. Interviews with ten students who had just finished a multivariable calculus course showed that the conjectured mental constructions are necessary.
The development of analogical reasoning : role of the executive component of inhibition
2011
We explored the development of the analogical reasoning. The traditional conception of this development is that it is dependent of knowledge accretion in children (Gentner, 1983, 1988; Goswami & Brown, 1989, 1990). We used a different approach which explains it as dependent of the development of the executive functions, particularly of the component of inhibition. The capacity of inhibition allows the suppression of the salient but irrelevant information for analogy-making in children. It is required while searching for the analogical solution. Nine studies involving a classical analogy-making task A : B :: C : ? were performed in this dissertation. The role of the capacity of inhibition wa…
Analogical reasoning and its development : role of executive functions and the goal of the task
2013
This manuscript develops an issue related to the involvement of goal management capabilities and executive functions in this type of reasoning and its development. The first three experiments examine this issue in two tasks of analogical reasoning, the scene analogy task and the A:B::C:? task, through the study of visual strategies used by adults, and children aged 6-to-7. The results show differences in visual patterns related to goals, and to the inhibition of irrelevant information for the solution of the problems, between the different tasks, and between children and adults. The following two experiments study the visual strategies, always in relation to executive functioning and goal m…
Mutual inductance for an explicitly finite number of turns
2011
Published version of an article published in Progress In Electromagnetics Research B, 28, 273-287. Also available from the publisher at http://www.jpier.org/pierb/pier.php?paper=10110103 Non coaxial mutual inductance calculations, based on a Bessel function formulation, are presented for coils modelled by an explicitly finite number of circular turns. The mutual inductance of two such turns can be expressed as an integral of a product of three Bessel functions and an exponential factor, and it is shown that the exponential factors can be analytically summed as a simple geometric progression, or other related sums. This allows the mutual inductance of two thin solenoids to be expressed as an…
Attitude Function as a Moderator in Values-Attitudes-Behavior Relations
2011
Abstract The aim of the present study was to find whether attitude functions could be useful in predicting aberrant driving. One of the attitudes functions is to express values; hence, we hypothesized that attitudes whose function is to express values will better predict traffic violations. We explored: (i) values in relation to attitudes towards aberrant driving behavior by regression analysis; (ii) and we explored moderating role of attitude functions in value-attitude-behavior relations. The study sample included 305 respondents who completed self-report questionnaires. Current research confirms previous results and also shows that values do predict attitudes when individual had formed h…
L'attività normativa del governo nel periodo 2017-2019
2022
L’articolo descrive l’attività normativa del governo nel periodo 2017-2019. Per quanto riguarda le procedure di programmazione e revisione della spesa pubblica, le riforme del 2016 finalizzate alla riduzione della spesa dei Ministeri hanno trovato applicazione solo nel 2017, mentre nel 2018 e nel 2019 ulteriori risparmi sono stati conseguiti mediante apposite previsioni delle leggi di bilancio. Le principali innovazioni in materia di liberalizzazione sono state portate a termine nel 2017, mentre non vi sono stati interventi rilevanti nel biennio successivo. Per quanto concerne il decentramento di funzioni amministrative, non si sono riscontrati progressi. Le politiche di privatizzazione son…
Multicenter Consistency Assessment of Valvular Flow Quantification With Automated Valve Tracking in 4D Flow CMR
2021
OBJECTIVES This study determined: 1) the interobserver agreement; 2) valvular flow variation; and 3) which variables independently predicted the variation of valvular flow quantification from 4-dimensional (4D) flow cardiac magnetic resonance (CMR) with automated retrospective valve tracking at multiple sites. BACKGROUND Automated retrospective valve tracking in 4D flow CMR allows consistent assessment of valvular flow through all intracardiac valves. However, due to the variance of CMR scanners and protocols, it remains uncertain if the published consistency holds for other clinical centers. METHODS Seven sites each retrospectively or prospectively selected 20 subjects who underwent whole …
Divario territoriale, coesione sociale e tutela dei diritti: il ruolo delle regioni in tempo di crisi
2021
L���articolo si occupa di verificare il ruolo delle regioni in tempo di crisi, finanziaria prima e sanitaria oggi, sia con riferimento alla gestione dell���emergenza pandemica, sia con riguardo alla gestione dei fondi del PNRR, in funzione del difficile tentativo di superare il divario territoriale, e in particolare il divario Nord-Sud, a garanzia di una maggiore protezione dei diritti delle autonomie e dunque della persona.
