Post-task Effects on EEG Brain Activity Differ for Various Differential Learning and Contextual Interference Protocols
2017
A large body of research has shown superior learning rates in variable practice compared to repetitive practice. More specifically, this has been demonstrated in the contextual interference (CI) and in the differential learning (DL) approach that are both representatives of variable practice. Behavioral studies have indicate different learning processes in CI and DL. Aim of the present study was to examine immediate post-task effects on electroencephalographic (EEG) brain activation patterns after CI and DL protocols that reveal underlying neural processes at the early stage of motor consolidation. Additionally, we tested two DL protocols (gradual DL, chaotic DL) to examine the effect of di…
Class discovery from semi-structured EEG data for affective computing and personalisation
2017
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link. Many approaches to recognising emotions from metrical data such as EEG signals rely on identifying a very small number of classes and to train a classifier. The interpretation of these classes varies from a single emotion such as stress [24] to features of emotional model such as valence-arousal [4]. There are two major issues here. First classification approach limits the analysis of the data within the selected classes and is also highly dependent on training data/cycles, all of which limits generalisation. Second issue is that it does not exp…
3D DCE-MRI Radiomic Analysis for Malignant Lesion Prediction in Breast Cancer Patients
2022
Rationale and Objectives: To develop and validate a radiomic model, with radiomic features extracted from breast Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) from a 1.5T scanner, for predicting the malignancy of masses with enhancement. Images were acquired using an 8-channel breast coil in the axial plane. The rationale behind this study is to show the feasibility of a radio-mics-powered model that could be integrated into the clinical practice by exploiting only standard-of-care DCE-MRI with the goal of reducing the required image pre-processing (ie, normalization and quantitative imaging map generation).Materials and Methods: 107 radiomic features were extracted from a …
Investigating Centrality Measures in Social Networks with Community Structure
2021
Centrality measures are crucial in quantifying the influence of the members of a social network. Although there has been a great deal of work dealing with this issue, the vast majority of classical centrality measures are agnostic of the community structure characterizing many social networks. Recent works have developed community-aware centrality measures that exploit features of the community structure information encountered in most real-world complex networks. In this paper, we investigate the interactions between 5 popular classical centrality measures and 5 community-aware centrality measures using 8 real-world online networks. Correlation as well as similarity measures between both t…
Mobiiliopetuksen käyttömahdollisuuksia : oppilaiden omien mobiililaitteiden käyttö peruskoulun alakoulun opetuksessa
2015
Muutaman viime vuoden aikana mobiililaitteiden käyttö kouluissa on yleistynyt. Tämä on osittain aiheuttanut ristiriitaista keskustelua laitteiden käytöstä opetuksessa. Osa opettajista on ottanut mobiililaitteet opetuskäyttöön innokkaasti. Mobiiliopetuksen mahdollisuuksia ei kuitenkaan ole vielä kovin paljon tutkittu. Tällä tutkimuksella oli tarkoitus selvittää, mitä mahdollisuuksia oppilaiden omat mobiililaitteet tarjoavat opetukseen. Aineiston analyysissa pyrittiin etsimään tietoa siitä, miten ongelma-perustaisen opetuksen menetelmä ja pelillisyys vaikuttavat opetus- ja oppimisprosessissa, kun opiskelumenetelmänä käytetään mobiilioppimista ja oppilaiden omia mobiililaitteita. Tutkimus teht…
A new reading of Bronze Age funerary structures in Mongolia through the analysis of their architectural elements, arrangement and form
2022
The archaeological landscape of Mongolia is marked by the presence of numerous funerary monuments (khirigsuurs) and engraved stelae (deer stones), erected by nomadic populations at the end of the Bronze Age. The first observations indicate great regularity in the choice and arrangement of the architectural and iconographic elements at the time when these structures were built. This regularity suggests the existence of shared traditions and social coherence between nomadic communities in a territory covering almost twice that of France. The data available today do not provide sufficient perspective to establish social models at the level of a province, and even less so at the scale of the co…

Vēstures un angļu valodas integrēta apguve 9.klasē
2019
Globalizācija ir daļa no mūsu dzīves mūsdienas un tās nozīme tikai palielinās. Satura un valodas integrēta apguve ir plaši atzīta ne tikai Eiropā, bet arī visa pasaulē jau no 1990-tajiem gadiem. Satura un valodas integrēta apguve ir ļoti populāra, jo skolēniem arvien vairāk nepieciešama angļu valoda, lai turpinātu savas studijas. Viņiem niepieciešamas angļu valodas zināšanas akadēmiskā akademiskā līmeni, lai sekmīgi turpinātu studijas un saprast dažādus jēdzienus, ko lieto viņu izvēlētajā priekšmetā. Jēdzienus neapgūst angļu valodas stundās. Satura un valodas integrēta apguve nozīmē aktīvu starppriekšmetu saikni. Skolēni mācās angļu valodu ne tikai angļu valodas stundās, bet viņi izmanto an…
Explaining Individual and Collective Programming Students’ Behavior by Interpreting a Black-Box Predictive Model
2021
Predicting student performance as early as possible and analysing to which extent initial student behaviour could lead to failure or success is critical in introductory programming (CS1) courses, for allowing prompt intervention in a move towards alleviating their high failure rate. However, in CS1 performance prediction, there is a serious lack of studies that interpret the predictive model’s decisions. In this sense, we designed a long-term study using very fine-grained log-data of 2056 students, collected from the first two weeks of CS1 courses. We extract features that measure how students deal with deadlines, how they fix errors, how much time they spend programming, and so forth. Subs…
NAVIGAZIONE WEB CONDIVISA ED E-CONFERENCE COME STRUMENTI DI APPRENDIMENTO
2009
La ricerca riguarda una sperimentazione, nell’ambito di percorsi universitari in blended e-learning che ha come obiettivo l’individuazione di buone pratiche a sostegno di percorsi di apprendimento in settori specialistici che richiedono un’interazione più assidua e diretta tra studenti e docenti /tutor. Alcuni autori affermano che le capacità di comunicazione asincrona della rete facilitano esperienze di apprendimento contemporaneamente indipendenti e collaborative (cfr. Garrison e Kanuka, 2004). Nella comunicazione via web forum si sviluppano discussioni, si intessono relazioni, ci si confronta sui vari temi, si scambiano opinioni, avendo in genere sufficiente tempo per trattare i vari arg…
