Lähdekielen vaikutus ja kielitaitotasot: paikallissijojen kehitys oppijansuomessa
2013
Artikkelissa tarkastelemme, millaista funktioltaan konkreettisten ja abstraktien paikallissijojen kaytto on oppijansuomessa. Tutkimuksen lahtokohtana on Eurooppalainen viitekehys: kielten oppiminen, opettaminen, arviointi (2003, tasta lahtien EVK) ja sen kielitaitotasot A1–C2. Tavoitteena on selvittaa, miten eri kielitaitotasoilla olevat oppijat kayttavat suomen paikallissijoja ja millainen on laheisen sukukielen viron mahdollinen vaikutus paikallissijojen kayton kehittymiseen kielitaitotasoittain. Tutkimusaineisto koostuu Oulun Kansainvalisen oppijansuomen korpuksen (ICLFI) vironkielisten oppijoiden osakorpuksen ja YKI-tutkintojen korpuksen kirjallisista teksteista. Aineistoa analysoidaan …
Understanding Estonian phraseological units on the basis of Finnish : contributing and misleading factors
2020
Vironkielistä tekstiä lukevien suomalaisten on havaittu hyödyntävän monenlaisia strategioita selvittääkseen sukukielen sanojen merkityksiä. Yksi niistä on pohjustaminen (priming). Kun kyseessä on fraseologinen yksikkö, yksi osa (prime) pohjustaa toisen osan eli kohdesanan (targetin) esiintymistä, mikäli prime on tunnistettavissa äidinkielen perusteella. Tässä artikkelissa kuvaamme muutamia erityistilanteita. Miten pohjustimen ja kohdesanan välinen etäisyys tai teemanvaihdos vaikuttavat ’petollisen ystävän’ ymmärtämiseen? Lisäksi tutkimme sitä, miten ahdasrajainen semanttinen kategoria ohjaa siitä puuttuvan jäsenen merkityksen löytämistä ja millaisia perusteita käännösratkaisuille on löydett…
Helppoa vai vaikeaa arvioida? : Yleisten kielitutkintojen suomen kielen arvioijien käsityksiä vironkielisten arvioinnista
2016
Finnish raters’ beliefs about assessing Estonian speakers in a Finnish language test: easy or difficult? This paper aims to contribute to our understanding on rater beliefs and views and to promote transparency in rater’s work in the form of reflection. The paper focuses on professional Finnish raters’ beliefs and views of assessing L1 Estonian speakers in the criteria-referenced Finnish language test of the National Certifi- cates of Language Proficiency test system. Finnish raters (N = 27) were asked via email to shortly reflect on what they find easy and what difficult in rating Estonian speakers’ writing and speaking skills in the Finnish language test. The raters reflected on many issu…
Spin Pumping and Torque Statistics in the Quantum Noise Limit
2017
We analyze the statistics of charge and energy currents and spin torque in a metallic nanomagnet coupled to a large magnetic metal via a tunnel contact. We derive a Keldysh action for the tunnel barrier, describing the stochastic currents in the presence of a magnetization precessing with the rate Ω. In contrast to some earlier approaches, our result is valid for an arbitrary ratio of ℏΩ/kBT. We illustrate the use of the action by deriving spintronic fluctuation relations, the quantum limit of pumped current noise, and consider the fluctuations in two specific cases: the situation with a stable precession of magnetization driven by spin transfer torque, and the torque-induced switching betw…
Game-Theoretic Approach to Hölder Regularity for PDEs Involving Eigenvalues of the Hessian
2021
AbstractWe prove a local Hölder estimate for any exponent $0<\delta <\frac {1}{2}$ 0 < δ < 1 2 for solutions of the dynamic programming principle $$ \begin{array}{@{}rcl@{}} u^{\varepsilon} (x) = \sum\limits_{j=1}^{n} \alpha_{j} \underset{\dim(S)=j}{\inf} \underset{|v|=1}{\underset{v\in S}{\sup}} \frac{u^{\varepsilon} (x + \varepsilon v) + u^{\varepsilon} (x - \varepsilon v)}{2} \end{array} $$ u ε ( x ) = ∑ j = 1 n α j inf dim ( S ) = j sup v ∈ S | v | = 1 u ε ( x + ε v ) + u ε ( x − ε v ) 2 with α1,αn > 0 and α2,⋯ ,αn− 1 ≥ 0. The proof is based on a new coupling idea from game theory. As an application, we get the same regularity estimate for viscosity solutions of the PDE $…
Toimijuus korkeakoulutettujen suomen oppijoiden visuaalisissa narratiiveissa
2018
This socioculturally informed study explores how highly educated Finnish language learners represent their agency in visual narratives. Learners (n=59) were asked to draw two pictures of themselves as Finnish language users and provide verbal interpretations of the drawings. The aim of using visual narratives is to reach aspects such as feelings and beliefs which might be difficult to express verbally. The data were analyzed first by using visual grammar set out by Kress and van Leeuwen (2006) and secondly by content analysis. The findings suggest that learners saw Finnish language as a tool for oral communication. However, difficulties with speaking and listening appeared to restrict learn…
Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction
2020
Visual distraction by secondary in-car tasks is a major contributing factor in traffic incidents. In-car user interface design may mitigate these negative effects but to accomplish this, design factors’ visual distraction potential should be better understood. The effects of touch screen size, user interface design, and subtask boundaries on in-car task's visual demand and visual distraction potential were studied in two driving simulator experiments with 48 participants. Multilevel modeling was utilized to control the visual demands of driving and individual differences on in-car glance durations. The 2.5” larger touch screen slightly decreased the in-car glance durations and had a diminis…
La visualisation au service de l'analyse d'interactions Implémentation d'une forme de visualisation générique au sein d'un environnement d'analyse de…
2009
International audience; La visualisation de traces d'interactions est une composante importante de leur analyse dans le cadre de l'évaluation d'usages d'EIAH collaboratifs. Différentes présentations permettent en effet aux chercheurs de plus facilement explorer des corpus parfois très complexes. Dans cet article, nous examinons les besoins de chercheurs désirant visualiser et analyser des traces d'interaction et introduisons la notion de partition d'interaction, une forme générique de visualisation adaptée à ces besoins. Nous montrons de quelle manière cette fonction a été implémentée au sein de Tatiana, un environnement d'analyse de traces. En particulier, nous illustrons comment l'archite…
Positive Effects of Videogame Use on Visuospatial Competencies: The Impact of Visualization Style in Preadolescents and Adolescents
2019
Use of videogames (VGs) is almost ubiquitous in preadolescents' and adolescents' everyday life. One of the most intriguing research topics about positive effects of VG use is about the domain of visuospatial competencies. Previous research show that training with videogames enables children and adolescents to improve their scores in visuospatial tests (such as mental rotation of shapes and cubes), and that such training could overcome gender differences in these domains. Our study aimed at (1) verifying the positive effects of videogame use in the visuospatial domain both for male and female adolescents and preadolescents and (2) verifying whether the visualization style (2D or isometric 3D…
