Scaffolding through dialogic teaching in early school classrooms
2016
The present study examines what types of dialogic teaching patterns can be identified in the early school years, and how teachers scaffold children's participation and shared understanding through dialogic teaching. Thirty recorded lessons from preschool to Grade 2 in Finnish classrooms were analysed using qualitative content analysis. Two teacher-initiated and two child-initiated dialogic teaching patterns were identified. Teacher's scaffolding in teacher-initiated dialogues was characterised by high responsibility in maintaining the interactional flow and utilisation of diverse strategies. In the child-initiated dialogues, the teachers' scaffolding consisted of listening and inquiry, and …
"Teachers teach so well that it's nice to learn" : a case-study on the role of teacher-to-student feedback in attitude-formation on L2 elementary Eng…
2015
Arviointi ja palautteenanto ovat oleellisia asioita opettajan jokapäiväisessä työssä. Lisäksi asenteiden tutkiminen on tällä hetkellä suosittu tutkimusala. Tässä tapaustutkimuksessa tutkittiin, millaista vuorovaikutuksellista palautetta opettaja antaa oppilailleen alakoulun englannin kielen tunneilla, ja millainen yhteys sillä on oppilaiden asenteisiin englannin kieltä kohtaan. Tutkimusaineisto koostui kolmesta opettajasta ja heidän oppilaistaan; yksi englannin kielen aineenopettaja ja hänen viidesluokkalainen ryhmänsä sekä kaksi luokanopettajaa ja heidän neljäs- ja viidesluokkalaisensa. Tutkimusaineisto koottiin metodisella triangulaatiolla. Aluksi oppilaille teetettiin kartoittava kysely …

Educational innovation through ICTs in the university setting. What do students think of these practices?
2014
Aquest document vol donar a conèixer l'experiència duta a terme per un grup d'estudiants durant el desenvolupament d'un programa destinat a alumnes innovadors de la Universitat de València. La immersió actual de les tecnologies en tots els àmbits de la societat i en l'educació planteja noves incògnites sobre com es desenvolupen aquestes experiències educatives. El projecte presentat era enfocat als alumnes amb vista a desenvolupar un treball que relacionés les tecnologies de la informació i la comunicació (TIC) amb els contextos d'aprenentatge universitaris. Així, en l'article es presenten les experiències, vivències i conclusions a les quals s'ha arribat quan s'ha acabat el projecte.
Mobile phones, identity and discursive intimacy
2005
This paper deals with the sociocultural effects of mobile phones in Philippine society. In particular it looks at how mobile phones have affected notions of identity and the rise of the sexual subject. It also deals with the political possibilities and implication of this new communicative technology in a society with previously poorly developed telephonic and other communicative technologies. Mobile phones allow absent subjects to exercise a daily presence in their communities of origin. This absent presence generates virtual subjects interacting primarily via the mobile phone.
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
The Case of Insertional Adductor Tendinopathy of an International-Level 3,000-m Steeplechase Runner
2021
Background: Groin pain is a frequent condition among athletes. One of the causes of groin pain is tendinopathy, a frequently diagnosed medical condition, which can also occur in the adductor muscles. Despite the high prevalence of this medical condition among athletes, it is infrequent to observe tendinopathic groin pain in steeplechase runners. The aim of this case study is to describe the case of an international-level 3,000-m steeplechase runner with groin pain, who was subsequently diagnosed with adductor insertional tendinopathy.Case Presentation: We present the case of an Italian 3,000-m steeplechase and long distance runner, Ala Zoghlami (180 cm, 57 kg), with groin pain, diagnosed as…
Decagram-Scale Synthesis of Multicolor Carbon Nanodots: Self-Tracking Nanoheaters with Inherent and Selective Anticancer Properties
2022
Carbon nanodots (CDs) are a new class of carbon-based nanoparticles endowed with photoluminescence, high specific surface area, and good photothermal conversion, which have spearheaded many breakthroughs in medicine, especially in drug delivery and cancer theranostics. However, the tight control of their structural, optical, and biological properties and the synthesis scale-up have been very difficult so far. Here, we report for the first time an efficient protocol for the one-step synthesis of decagram-scale quantities of N,S-doped CDs with a narrow size distribution, along with a single nanostructure multicolor emission, high near-infrared (NIR) photothermal conversion efficiency, and sel…
The Scope of Application of Macrocyclic Polyamines Beyond Metal Chelation
2019
International audience; Recent advances in the use of radiometals for both imaging and therapy has spurred on the development of an original chemistry that endows radionuclide-chelating molecular cages with ever sharper physicochemical properties. Macrocyclic polyamines (MPAs) such as cyclen and DOTA are among the most frequently encountered cages for the design of new radiotracers, owing to their versatile chemistry that makes them customizable molecular tools. The idea of using MPAs for alternative purposes has recently emerged, with an eye towards benefiting from their unique topology, versatility, symmetry and water-solubility. This review summarizes strategies that have been recently i…
Interactive Tools for the Preservation, Dissemination and Study of Silk Heritage—An Introduction to the SILKNOW Project
2018
Silk was a major factor for progress in Europe, mostly along the Western Silk Road’s network of production and market centers. The silk trade also allowed for the exchange of ideas and innovations, having impacts at economic, technical, functional, cultural and symbolic levels. However, silk has today become a seriously endangered heritage. Although many European specialized museums are devoted to its preservation, they usually lack the size and resources to take advantage of state-of-the-art digital technologies. The aim of this paper is twofold; firstly, we introduce SILKNOW, an interdisciplinary project that has been recently funded by the H2020 Programme of the European Union in order t…
