Les théoriciens spontanés : comment les évaluateurs construisent et révisent leurs connaissances des programmes par l'expérience
2021
International audience; What exactly do evaluators learn about programs through experience and how? We chose a constructivist framework to investigate the structure of evaluators’ program-related knowledge, namely the form, content, and origins of their expressed theories. In this context, we complemented a Piagetian theory of learning with new developments offered by “probabilistic” (or “Bayesian”) models of learning. We conducted “explicitation” interviews with nine experienced practitioners, some specializing in the education or agri-environment sectors and some generalists. After examining the form and content of their program-related knowledge, we examine its development through experi…
Dagli obiettivi educativi alle competenze fondamentali
2014
Insegnare e valutare per competenze costituisce la "nuova frontiera" della Didattica contemporanea. Il libro si colloca nella prospettiva della scuola delle competenze senza però disperdere quanto di positivo è stato acquisito nella pratica della didattica per obiettivi di "terza generazione", quella che fa riferimento al sistema degli obiettivi educativi "fondamentali". Si ritiene che le critiche alla progettazione e alla valutazione per obiettivi abbiano contribuito a diffondere una concezione più ampia degli obiettivi educativi, che ben si integra con la nuova prospettiva didattica delle competenze. Il sistema degli obiettivi fondamentali dell'educazione, descritto nel volume, costituisc…
Cross-Device Augmented Reality Annotations Method for Asynchronous Collaboration in Unprepared Environments
2021
Augmented Reality (AR) annotations are a powerful way of communication when collaborators cannot be present at the same time in a given environment. However, this situation presents several challenges, for example: how to record the AR annotations for later consumption, how to align virtual and real world in unprepared environments or how to offer the annotations to users with different AR devices. In this paper we present a cross-device AR annotation method that allows users to create and display annotations asynchronously in environments without the need for prior preparation (AR markers, point cloud capture, etc.). This is achieved through an easy user-assisted calibration process and a …
Une formation pédagogique peut-elle modifier les conceptions de jeunes enseignants universitaires sur l’apprentissage et l’enseignement ?
2012
Nous analysons l’évolution des conceptions de l’apprentissage et de l’enseignement de jeunes enseignants universitaires à l’issue d’une formation en pédagogie universitaire, grâce à des informations de formations collectées lors de sessions de formation de l’Université de Bourgogne. Nous montrons que les conceptions à l’entrée et à la sortie de formation apparaissent variées et que celles-ci sont liées aux disciplines, à l’expérience et au projet professionnel. Les participants considèrent avoir changé de conceptions au terme de la formation. Ceux qui ont des visions nuancées et centrées d’emblée sur l’apprenant sont toutefois davantage influencés par la formation pédagogique.
Warum ist Pränataldiagnostik in der Diskussion? Eine Einführung
2017
Prenatal diagnosis has been a subject of intense discussion since it became technically achievable. This is because the results it provides can dramatically change the attitude of mothers towards their unborn children, and can lead to considerable social pressure to abort the child. These undesirable effects might come as a surprise, given that prenatal testing was primarily intended to allow better care for infants waiting to be born. The possible risks of invasive procedures and the only statistical evidence of results are the factors most responsible for the ambivalent attitudes that surround prenatal diagnosis. Another significant factor is the discrepancy between the general availabili…
Controllo contabile e controllo di costituzionalità delle leggi: una diversa prospettiva sul giudizio di costituzionalità in via incidentale

Crystal structure of (2E)-3-[4-(dimethylamino)phenyl]-1-(thiophen-2-yl)prop-2-en-1-one
2017
In the title chalcone-thiophene derivative, the dihedral angle between the aromatic and the thiophene rings is 11.4 (2)°. In the crystal, molecules are linked by C—H⋯O and C—H⋯S weak interactions along [100], forming rings of R22(8) graph-set motif, by C—H⋯O weak interactions along [010], forming C(6) chains, and by weak H(methyl–group)⋯Cg(thiophene ring) interactions into dimers; the crystal packing resembles a herringbone arrangement when viewed along [100]. A molecular docking calculation of the title compound with the neuraminidase enzyme was carried out.
Communication-Efficient Federated Learning in Channel Constrained Internet of Things
2022
Federated learning (FL) is able to utilize the computing capability and maintain the privacy of the end devices by collecting and aggregating the locally trained learning model parameters while keeping the local personal data. As the most widely-used FL framework,Jederated averaging (FedAvg) suffers an expensive communication cost especially when there are large amounts of devices involving the FL process. Moreover, when considering asynchronous FL, the slowest device becomes the bottleneck for the cask effect and determines the overall latency. In this work, we propose a communication-efficient federated learning framework with partial model aggregation (CE-FedPA) algorithm to utilize comp…
Topical anti-inflammatory potential of quercetin in lipid-based nanosystems: In vivo and in vitro evaluation
2013
Purpose: To develop quercetin-loaded phospholipid vesicles, namely liposomes and PEVs (Penetration Enhancer-containing Vesicles), and to investigate their efficacy on TPA-induced skin inflammation. Methods: Vesicles were made from a mixture of phospholipids, quercetin and polyethylene glycol 400 (PEG), specifically added to increase drug solubility and penetration through the skin. Vesicle morphology and self-assembly were probed by Cryo-Transmission Electron Microscopy and Small/Wide Angle X-ray Scattering, as well as the main physico-chemical features by Light Scattering. The anti-inflammatory efficacy of quercetin nanovesicles was assessed in vivo on TPA-treated mice dorsal skin by the d…
STRAIN ENERGY EVALUATION IN STRUCTURES HAVING ZONE-WISE PHYSICAL- MECHANICAL QUANTITIES
2013
Among the possible aims of structural analysis inside some engineering spheres it can be useful to know the strain energy stored in all or in a part of the structure caused by assigned external actions, like the boundary and domain quantities. This serves to evaluate globally whether an assigned portion of structure undergoes an excessive store of energy able to compromise the stability of all the structure. This evaluation can be carried out through boundary work obtained using appropriate boundary generalized quantities connected to the results of the analysis on the whole structure. The advantage consists in using a very restricted number of quantities which, because of the characteristi…
