Photocycle of point defects in highly- and weakly-germanium doped silica revealed by transient absorption measurements with femtosecond tunable pump.
2022
AbstractWe report pump-probe transient absorption measurements addressing the photocycle of the Germanium lone pair center (GLPC) point defect with an unprecedented time resolution. The GLPC is a model point defect with a simple and well-understood electronic structure, highly relevant for several applications. Therefore, a full explanation of its photocycle is fundamental to understand the relaxation mechanisms of such molecular-like systems in solid state. The experiment, carried out exciting the sample resonantly with the ultraviolet (UV) GLPC absorption band peaked at 5.1 eV, gave us the possibility to follow the defect excitation-relaxation dynamics from the femto-picosecond to the nan…

Återbesök till feedback : en fallstudie av fokus och form på webbkursen Hjälpis
2017
Tämän maisterintutkielman tutkimuskohteena on palaute Jyväskylän yliopiston Kielikeskuksen valinnaisella ruotsin Hjälpis-verkkokurssilla. Tutkintovaatimuksiin pakollisena kuuluvan toisen kotimaisen kielen, ruotsin taitojen osoittamisen KORU-arviointikriteerien B1-tasolla on aikaisemmissa tutkimuksissa arvioitu olevan haaste riittämättömien taitojen takia jopa puolelle yliopisto-opiskelijoista. Koulutusasteelta toiselle siirryttäessä minimivaatimustaso on korkeampi eikä nivelly, jos opiskelijat ovat selvinneet kursseista lukiossa vain oppimäärän vähimmäistavoitteet saavuttaen. Hjälpis-kurssilla tätä puutteellisen osaamistason ja vaatimusten välistä eroa pyritään kaventamaan itseohjautuvuudel…
Entropic model application to identify cross-sectional flow effect on velocity distribution in a large amplitude meandering channel
2020
Abstract Literature shows the application of the entropy concept in open channels flow. No existing research has been addressed to the application of the entropy concept for evaluating the effect of secondary flow which especially develops in curved channels. The purpose of this paper is to explore the possibility to evaluate the effect of the secondary flow on the stream-wise velocity distribution starting only from the knowledge of the surface velocity and the entropic concept application. The analysis is conducted with the aid of data collected in a large-amplitude meandering laboratory flume for two different values of the width-to-depth ratio. Results show that the location of the maxi…
Evaluation d'une innovation pédagogique au lycée : l'aide individualisée en seconde
2001
Notes de l'Irédu - IREDU - Université de Bourgogne; La mise en place de l’aide individualisée (A.I.S.) a été un élément de la réforme des lycées. Ce dispositif prévoyait une dotation de deux heures dans l’emploi du temps hebdomadaire de la classe de seconde pour des élèves qui rencontrent des difficultés ponctuelles ou présentent des lacunes plus profondes en français et en mathématiques. Cette recherche rend compte des résultats d'une évaluation réalisée sur la première année de mise en place. Le caractère peu ciblé du dispositif, une incohérence relative dans l’allocation des moyens aux établissements, le faible nombre de séances suivies par les élèves sont des éléments explicatifs de l'a…
The evolution and ecology of multiple antipredator defences
2023
Prey seldom rely on a single type of antipredator defence, often using multiple defences to avoid predation. In many cases, selection in different contexts may favour the evolution of multiple defences in a prey. However, a prey may use multiple defences to protect itself during a single predator encounter. Such “defence portfolios” that defend prey against a single instance of predation are distributed across and within successive stages of the predation sequence (encounter, detection, identification, approach (attack), subjugation and consumption). We contend that at present, our understanding of defence portfolio evolution is incomplete, and seen from the fragmentary perspective of speci…
Soborowe nauczanie o sztuce
2021
Sztuka kościelna w chrześcijaństwie nie jest sprawą fakultatywną, ale wyrazem dogmatu o Wcieleniu Boga w Jezusie Chrystusie. W swej historii Kościół wypowiedział się w czterech soborach ekumenicznych na temat sztuki kościelnej, jej znaczenia, formacji artystów, kapłanów. Nauka soborów ma swój rozwój: najpierw odpowiada na pytania w ogóle o możliwość tworzenia obrazów, następnie o to, jakie obrazy mogą znajdować się w kościele, kto je może tworzyć, oraz o odpowiedzialność pasterzy za prawidłowe powiązanie obrazu z liturgią. Ostatecznie można odtworzyć pełną naukę soborów odnośnie do wykształcenia i formacji artystów (ikonografów), opieki duchowieństwa nad artystami i sztuką kościelną, oraz t…
Drawing techniques as tools for the evaluation of scholastic integration and emotional components in primary and secondary school : a cross-sectional…
2023
IntroductionIn the last decades, many studies have emphasized emotion’s role in psycho-educational processes during childhood, such as scholastic integration. Emotional variables in childhood can be assessed through projective graphic techniques, as they allow children to use kinetic components of the draws to communicate emotions.Method1.757 couple of draws were collected, from primary school children (N = 1.270; F = 643 [50.6%]; Age = 8.6; SD = 1.31) and secondary school children (N = 487; F = 220 [45.2%]; Age = 11.72; SD = 0.70) and from eight schools in Sicily and over 60 different classrooms. The Drawn Stories Technique and the Classroom Draw were used to assess children’s current emot…
