Improving statistical classification methods and ecological status assessment for river macroinvertebrates
2016
Aquatic ecosystems are facing a growing number of human-induced stressors and the need to implement more biomonitoring to assess the ecological status of water bodies is eminent. This dissertation aims at providing tools to reduce the costs and improve the accuracy of freshwater benthic macroinvertebrate biomonitoring. To improve the cost-e ciency, we consider automated classi cation and develop a novel classi er suitable for complex macroinvertebrate image data. To enhance the accuracy of macroinvertebrate biomonitoring, we study the statistical properties of the Percent Model A nity index crucial to current Finnish biomonitoring and the factors a ecting these statistics. Finally, we perfo…

L’approccio dell’etichettamento nello studio della devianza
2020
Il saggio in questione – inserito originariamente in un volume interdisciplinare dedicato alla classificazione dei bambini “con bisogni speciali” – indica come il processo sociale di classificazione sia esso stesso oggetto dell’analisi perché «concepire il problema dei bambini con bisogni speciali in questo modo ci porta a problematizzare il modo in cui è apparsa la stessa categoria», individuando la natura anche politica del processo di definizione del “deviante” che necessita di un approfondimento delle dinamiche storiche, culturali, sociali, politiche, giuridiche che producono le diverse categorie di “bambini con bisogni speciali”. Gli usi della classificazione all’interno delle agenzie …
Calcium mediated polyelectrolyte adsorption on like-charged surfaces.
2011
International audience; Monte Carlo simulations within the primitive model of calcium-mediated adsorption of linear and comb polyelectrolytes onto like-charged surfaces are described, focusing on the effect of calcium and polyion concentrations as well as on the ion pairing between polymers and calcium ions. We use a combination of Monte Carlo simulations and experimental data from titration and calcium binding to quantify the ion pairing. The polymer adsorption is shown to occur as a result of surface overcharging by Ca2+ and ion pairing between charged monomers and Ca2+. In agreement with experimental observations, the simulations predict that the polymer adsorption isotherm goes through …
Predicting Individual Differences from Brain Responses to Music using Functional Network Centrality
2022
Individual differences are known to modulate brain responses to music. Recent neuroscience research suggests that each individual has unique and fundamentally stable functional brain connections irrespective of the task they perform. 77 participants’ functional Magnetic Resonance Imaging (fMRI) responses were measured while continuously listening to music. Using a graph-theory-based approach, we modeled whole-brain functional connectivity. We then calculate voxel-wise eigenvector centrality and subsequently use it to classify gender and musical expertise using binary Support Vector Machine (SVM). We achieved a cross-validated classification accuracy of 97% and 96% for gender and musical exp…
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…
Guiding and assessing development of L2 writing process : the role of peer collaboration
2022
This study, informed by Vygotskian notion of mediation and reporting on a partnership between a researcher (the first author) and a teacher (the second author), aims at exploring how peers’ comments can inform teacher assessment and guidance of learners’ L2 (second/foreign language) writing. The participants were 19 L2 English learners in an upper secondary school in Finland. We largely focus on the notes that one pair of learners made on each other’s essays and how they responded to peer assistance. Triangulating these data with classroom observation and a questionnaire, we traced how learners co-constructed their understanding of how their texts can be developed. The foci and how the iden…
Imagined Identities and Communities in the Learning Context of Finnish as a Second Language
2022
This case study on two migrant pupils of Finnish as L2 was carried out in Finland, which lies outside the most common context of such research, i.e. ESL or EFL in an English-speaking country. The study thus attempts to address the need to expand the research contexts of L2 identity issues. Using ethnographic data collected inside and outside a preparatory language classroom, this study aims to examine how the pupils make sense of their new learning environment and how, through language learning, they construct identities. The results show that they extend their repertoire of identities and connect to a wider world of possibilities as they strive to gain greater resources in their imagined c…
