Italian Amateur Pop-Rock Musicians on Facebook
2017
This chapter investigates how and why amateur musicians use social networking sites, employing a mixed-methods approach. Attention is focused on four big Italian Facebook communities of pop-rock musicians: drums, bass, guitar, and keyboard players (overall, 2,101 active users), analyzing the relational and textual data extracted from the web. The chapter analyzes the network structures emerging from the interactions among the users. It also identifies and maps the main areas of discussion (sound shaping, studio recording, marketplace, musical references, computer production, and relations) and the latent semantic dimension characterizing Facebook users’ activities, through social network an…
The focus and timing of gaze matters : Investigating collaborative knowledge construction in a simulation-based environment by combined video and eye…
2022
Although eye tracking has been successfully used in science education research, exploiting its potential in collaborative knowledge construction has remained sporadic. This article presents a novel approach for studying collaborative knowledge construction in a simulation-based environment by combining both the spatial and temporal dimensions of eye-tracking data with video data. For this purpose, we have investigated two undergraduate physics student pairs solving an electrostatics problem in a simulation-based environment via Zoom. The analysis of the video data of the students’ conversations focused on the different collaborative knowledge construction levels (new idea, explication, eval…
Ghost stochastic resonance in FitzHugh–Nagumo circuit
2014
International audience; The response of a neural circuit submitted to a bi-chromatic stimulus and corrupted by noise is investigated. In the presence of noise, when the spike firing of the circuit is analysed, a frequency not present at the circuit input appears. For a given range of noise intensities, it is shown that this ghost frequency is almost exclusively present in the interspike interval distribution. This phenomenon is for the first time shown experimentally in a FitzHugh-Nagumo circuit.
What do we do when we analyse the temporal aspects of computer-supported collaborative learning? A systematic literature review
2021
To better understand the premises for successful computer-supported collaborative learning (CSCL), several studies over the last 10 years have analysed the temporal aspects of CSCL. We broadly define the temporal aspects of CSCL as focusing on the characteristics of or interrelations between events over time. The analysis of these aspects, however, has been loosely defined, creating challenges regarding the comparability and commensurability of studies. To address these challenges, we conducted a systematic literature review to define the temporal analysis procedure for CSCL using 78 journal papers published from 2003 to 2019. After identifying the key operations to be included in the proce…
Peer selection and influence : Students’ interest-driven socio-digital participation and friendship networks
2020
Digital technologies have been increasingly embedded in students’ everyday lives. Interest-driven socio-digital participation (ISDP) involves students’ pursuit of interests mediated by computers, social media, the internet, and mobile devices’ integrated systems.ISDPis likely to intertwine closely with young people’s social networks that has been scarcely studied quantitatively. To close this gap, the present paper investigated students’ peer selection and influence effects of the intensity of their ISDP and friendship networks. We collected two-wave data by administering a peer nomination to trace students’ friendship networks with peers and a self-reported questionnaire to examine student…
La politica su Twitter: analisi di rete e sentiment analysis d'un caso studio
2021
Le interazioni sociali e le opinioni riguardanti la politica, espresse su Twitter da leader, candidati, normali cittadini o influencer, occupano una grossa parte del dibattito politico contemporaneo. Esse possono essere studiate facendo ricorso a tecniche computazionali, che comportano l’estrazione e l’analisi d’una enorme quantità di dati. In questo contributo, mostro le potenzialità di due di queste tecniche: la social network analysis e la sentiment analysis, indagando – come caso studio – il tema della scuola, oggetto di dibattito politico e trending topic su Twitter, nel settembre del 2020. A tale scopo, metto a confronto due reti di discussione diverse, una tematica e l’altra personal…
La colaboración científica: principales líneas de investigación y retos de futuro
2014
The construction of knowledge is a collaborative process that has seen a dramatic growth over recent decades, since almost all research activities now involve increasing numbers of researchers, institutions, disciplines and countries. The present study provides a bibliographic review of the literature on research collaboration and identifies pioneering work on the topic, the types of studies undertaken and the variables analyzed. Several approaches are discussed: the “classical” approach, based on bibliometric indicators, which has taken on a new dimension with Social Network Analysis; and quantitative and qualitative approaches, which attempt to investigate the motivations and dynamics of …
Setting Individual Goals for Pupils with Profound Intellectual and Multiple Disabilities : Engaging in the Activity Area-Based Curriculum Making
2021
The activity area-based curriculum model (AACM) is used in the Finnish basic education to support pupils—most of whom have profound intellectual and multiple disabilities (PIMD)—who could benefit more from skills that advance independent life coping. Existing studies have concentrated mainly on the Individual Education Plan (IEP) goal-setting process for pupils with milder disabilities than PIMD and have consistently demonstrated significant barriers in the process. This study explores the collaborative IEP goal-setting process for pupils with the AACM. Sixty-five Finnish special education teachers using the AACM participated in the study. Semi-structured interviews were analysed with thema…
