Modern Multispectral Sensors Help Track Explosive Eruptions
2013
Due to its massive air traffic impact, the 2010 eruption of Eyjafjallajokull was felt by millions of people and cost airlines more than U.S. $1.7 billion. The event has, thus, become widely cited in renewed efforts to improve real-time tracking of volcanic plumes, as witnessed by special sections published last year in Journal of Geophysical Research, (117, issues D20 and B9).
Mapping lava flows at Etna Volcano using Google Earth Engine, open-access satellite data, and machine learning
2021
Estimating eruptive parameters is fundamental to assess the volcanic hazards posed to the community living at the edge of active volcanoes. Here, we analyzed satellite remote sensing data by using machine learning unsupervised and supervised techniques and analytical approaches, i.e., mathematical-physics and statistics formulations, to map lava flows emitted during the long sequences of short-lived, violent eruptions occurred at Etna volcano between December 2020 and March 2021. Satellite observations allowed to follow the evolution of eruptions thanks to their capability to survey large areas with frequent revisit time and accurate spatial resolution. We quantified the areal coverage of l…
Un computer non più calcolatore. Linguistica e informatica
2004
La monografia analizza dal punto di vista sociocognitivo e linguistico il momento della evoluzione della percezione del computer da strumento ad ambiente di socialità, evidenziando le modifiche cognitive e sociali che comporta e la loro ricaduta nella didattica della lingua, soprattutto della lingua straniera. I tratti seminali dell'evoluzione appena visibili nel momento della pubblicazione del saggio hanno costituito la struttura del Web 2.0
Web, globalizzazione e minoranze
2007
L’espressione “apprendimento naturale” indica una liaison difficile: i due componenti del sintagma fanno riferimento a modalità glottodidattiche contrapposte, quella implicita e informale dell’acquisizione naturale e quella esplicita e formale dell’apprendimento di una L2. Essa non esprime la volontà di mettere in dubbio l’approccio naturale nell’apprendimento, ma propone di recuperare alcune modalità di conoscenza linguistica implicita proprie dell’acquisizione della L1 nella didattica della L2, estendendole, quantitativamente e qualitativamente, in modo che risultino rispettose della globalità e della sistematicità dell’acquisizione di conoscenze da parte della persona apprendente . Il su…

Data from: Predators’ consumption of unpalatable prey does not vary as a function of bitter taste perception
2019
Many prey species contain defensive chemicals that are described as tasting bitter. Bitter taste perception is therefore assumed to be important when predators are learning about prey defenses. However, it is not known how individuals differ in their response to bitter taste, and how this influences their foraging decisions. We conducted taste perception assays in which wild-caught great tits (Parus major) were given water with increasing concentrations of bitter-tasting chloroquine diphosphate until they showed an aversive response to bitter taste. This response threshold was found to vary considerably among individuals, ranging from chloroquine concentrations of 0.01 mmol/l to 8 mmol/l. W…
Description of movement sensor dataset for dog behavior classification
2022
The description and results of the original investigation are found in: Dog behaviour classification with movement sensors placed on the harness and the collar, Kumpulainen, P., Valldeoriola Cardó, A., Somppi, S., Törnqvist, H., Väätäjä, H., Majaranta, P., Gizatdinova, Y., Antink, C. H., Surakka, V., V. Kujala, M., Vainio, O. & Vehkaoja, A., Aug 2021, In: Applied Animal Behaviour Science. 241, 7 p., 105393. Movement sensor data from seven static and dynamic dog behaviors (sitting, standing, lying down, trotting, walking, playing, and (treat) searching i.e. sniffing) was collected from 45 middle to large sized dogs with six degree-of-freedom movement sensors attached to the collar and the ha…
Motivational Challenges of Engineers Participating in an Online Upskilling Program
2022
The present powerful surge of available online learning platforms will provide employees with enhanced opportunities to rapidly develop their skills, regardless of time and place. Despite the potential, there are challenges for participants on online learning platforms to finalise the courses they engage in. The reasons for the high number of students dropping out before completion of the course are motivational, social, and technological. Studies show that large skill gaps exist among industry employees worldwide. It is often caused by the implementation of new technologies, digitalization, as well as increasing requirements on sustainability and resilience. E-learning provides a major opp…
Exploring sequential interplay between challenges and regulatory processes in collaborative learning with process mining
2023
This study explored the sequential interplay between challenges and regulatory processes in high- and low-performing collaborative groups. 66 students from a Finnish higher education institution participated in a collaborative task in groups of three. Approximately 34 h of video data were coded. The sequential analysis revealed that both groups had higher sequential transitions between cognitive regulation and emotional/motivational regulation, rather than cognitive challenges. The high-performing groups demonstrated a stronger sequential link between emotional/motivational regulation and cognitive regulation than the low-performing groups did when faced with cognitive challenges. The study…
“You really brought all your feelings out” : Scaffolding students to identify the socio-emotional and socio-cognitive challenges in collaborative lea…
2021
The aim of this study is to explore how students experience and describe socio-cognitive and socio-emotional challenges in collaborative learning. The participants (N = 20) were teacher education students whose collaborative learning was supported with a designed regulation macro script during a six-week mathematics course. The purpose of the script was to provide structured phases during the collaborative learning tasks for the group members to plan, monitor, and evaluate their workings. The video data of groups' face-to-face work was collected and analysed by focusing on the different types of challenges the groups experienced and the types of challenges they described during the scripted…
