Photobleaching and Recovery Kinetics of a Palette of Carbon Nanodots Probed by In Situ Optical Spectroscopy

2022

Carbon dots (CDs) are a family of fluorescent nanoparticles displaying a wide range of interesting properties, which make them attractive for potential applications in different fields like bioimaging, photocatalysis, and many others. However, despite many years of dedicated studies, wide variations exist in the literature concerning the reported photostability of CDs, and even the photoluminescence mechanism is still unclear. Furthermore, an increasing number of recent studies have highlighted the photobleaching (PB) of CDs under intense UV or visible light beams. PB phenomena need to be fully addressed to optimize practical uses of CDs and can also provide information on the fundamental m…

Luminescent Silicon nanocrystals produced by ns pulsed laser ablation

2013

The reduction of Si down to nanoscale introduces a peculiar visible luminescence, surprisingly for a not highly emissive material. This feature is relevant in connection with several application fields (optoelectronics, medicine) and has lead the research towards the development of production methods successful to control the physical and chemical properties of the nanosized Si so as to enhance and tune the luminescence. To this purpose, the laser ablation in liquids is particularly promising since it provides effective controlling parameters (laser photon energy, fluence, repetition rate, liquid reactivity) for the morphology and the structure of Si-related products. Here we report a study…

La imprenta en México: cuestiones terminológicas y tipología de los primeros impresos americanos

2020

espanolLa cultura impresa mexicana tiene su origen en los albores del siglo XVI con la instalacion de la primera prensa tipografica en el continente y la fabricacion de las primeras ediciones impresas en el continente. Esta primitiva produccion, y cada uno de los ejemplares que la integraba, fechados entre 1539 y 1634, recibieron el nombre de incunables americanos a semejanza de los primeros libros impresos en Europa entre la creacion de la imprenta y el 1 de enero de 1501. Sin embargo, poco tenian que ver los iniciales americanos con los primeros textos impresos en Europa hacia mas de cincuenta anos, por lo que la utilizacion del termino incunable resulto desde un primer momento confusa. E…

The Art-Based Methods in Developing Transversal Competence

2019

This article describes a project called “The art based methods in developing transversal competence” funded by The Finnish National Board of Education. The article is based on the hermeneutic phenomenological approach in action research. The project developed learning environments as well as project-based learning with emphasis on the art-based methods and transversal competence approach to learning. The aim was to develop unique and communal well-being in learning. The project offered tools to strengthen teachers’ professional skills to use expressive, art-based methods in different curriculum-based projects. The professional in-service training project included five contact days in six we…

Connecting the Language Classroom and the Wild : Re-enactments of Language Use Experiences

2018

AbstractUsing multimodal conversation analysis, this article analyses language learning as an in situ process during a teacher-assigned, experientially based pedagogical activity. The activity involved a three-part pedagogical structure, where learners first prepared for and then participated in real-life service encounters, and later reflected on their experiences back in the classroom. The analysis details how the co-constructed telling sequences through which novice second language users re-enact their experiences create an occasion for language-focused activity. We argue that the actions through which the participants display and sustain an orientation to an interactional practice as an…

The role of motor system in action-related language comprehension in L1 and L2: An fMRI study

2018

The framework of embodied cognition has challenged the modular view of a language-cognition divide by suggesting that meaning-retrieval critically involves the sensory-motor system. Despite extensive research into the neural mechanisms underlying language-motor coupling, it remains unclear how the motor system might be differentially engaged by different levels of linguistic abstraction and language proficiency. To address this issue, we used fMRI to quantify neural activations in brain regions underlying motor and language processing in Chinese-English speakers’ processing of literal, metaphorical, and abstract language in their L1 and L2. Results overall revealed a response in motor ROIs …

Mehrsprachigkeit von Lernern mit Migrationshintergrund im finnischen Fremdsprachenunterricht : Perspektiven der Lerner, Lehrpersonen und Erziehungsbe…

2016

The goal of this study is to examine how the relatively new phenomenon of multilingualism in the Finnish education system is presently managed in foreign language classes in the Finnish comprehensive school. The focus is on how bi- and multilingual learners with migration background can benefit from their previous individual language experiences, language learning experiences and language awareness processes, and how these function as a resource for their further (foreign) language learning process. Until now migration research in the Finnish context concentrating on language learning mainly consists of second language acquisition. This study, however, focusses on foreign language learning …

How Wild Can It Get? Managing Language Learning Tasks in Real Life Service Encounters

2019

This chapter explores how experientially based pedagogical activities that involve participation in real life service encounters provide occasions for developing L2 interactional competence. The data comprises novice L2 students’ self-recorded interactions in service settings and videorecordings of classroom planning activities and de-briefing discussions, where the students reflect on their experiences. The analysis traces what kinds of occasions for learning arise as the students move between the classroom and the real-world service settings. The findings show that the different phases of the task complement each other in supporting the development of interactional competence. The prepara…

Genèse et mémoires des randonnées littéraires

2018

Depuis les années 1980, les randonnées littéraires autour d’écrivains sont associées à des lectures de romans en vue d’entretenir la vitalité d’une œuvre dans une perspective de valorisation. Si les mémoires collectives sont longtemps restées l’apanage des ethnologues, les maisons d’écrivains sont les premières institutions à développer un type d’itinéraires touristiques en lien avec les politiques locales. Utilisant une approche basée sur les ressources territoriales, il s’agit de revenir sur l’émergence des randonnées littéraires consacrées à Jean Giono et de resituer cette démarche dans son articulation avec l’offre touristique régionale. La célébration de cet auteur se concentre aujourd…
