Toimijuus ja vuorovaikutusjärjestys amerikkalaisten suomenoppijoiden itsenäisessä kielenkäytössä
2021
Aiemmat tutkimukset ovat osoittaneet vastakkainasettelun luokassa ja luokan ulkopuolella tapahtuvassa kielenkäytössä ja oppimisessa. Tässä artikkelissa tarkastelen neljää amerikkalaista suomenoppijaa ja sitä, miten he hakeutuvat aktiivisina toimijoina itsenäisiin suomen kielen käyttötilanteisiin. Artikkelin aineistona on portfoliotehtävä, jossa oppijat ovat dokumentoineet ja reflektoineet itsenäistä, luokkahuoneen ulkopuolella tapahtuvaa kielenkäyttöään. Tarkastelen aineistoa Scollonin ja Scollonin (2004) neksusanalyysia ja van Lierin (2010) ekologista viitekehystä hyödyntäen. Artikkelin analyysimenetelmänä on diskurssianalyysi. Portfolioissa dokumentoidut vuorovaikutustilanteet rakentuivat…
Anàlisi de la violència filioparental en centres de menors : un estudi monogràfic
2019
espanolAntecedentes: El principal objetivo de este estudio era conocer las caracteristicas sociodemograficas, judiciales y psicologicas de los menores infractores que habian sido denunciados por violencia filio-parental, asi como elaborar posibles perfiles a partir de dichas caracteristicas. Metodo: Se analizaron expedientes judiciales correspondientes a 56 adolescentes del Centro de Educacion e Internamiento por Medida Judicial de Zaragoza –Espana–, que habian sido internados por violencia filio-parental en el periodo comprendido entre 2006 y 2016.Resultados: Los resultados indican una importante presencia de antecedentes por acogimiento en centros de proteccion de menores, hogares familia…
Virtudes escolares percibidas por estudiantes y docentes ecuatorianos: diferencias según sexo, establecimiento y roles
2020
El objetivo del estudio es evaluar la virtuosidad percibida en organizaciones escolares y las diferencias por tipo de centro educativo (fiscal, municipal); sexo (mujer, hombre) y rol (estudiantes, docentes). Se trató de un estudio instrumental basado en el análisis de la estructura factorial y la fiabilidad de un cuestionario para evaluar virtudes percibidas en escuelas (VPOE); y, de un estudio descriptivo transversal que analizó diferencias por sexo, rol y tipo de organizaciones escolares con relación a las virtudes percibidas. Se trabajó con una muestra de 550 estudiantes (49.28 % mujeres) y 105 docentes (47.62% mujeres). El análisis factorial determinó un modelo de cuatro factores que pe…
SARS-CoV-2 envelope protein topology in eukaryotic membranes
2020
Coronavirus E protein is a small membrane protein found in the virus envelope. Different coronavirus E proteins share striking biochemical and functional similarities, but sequence conservation is limited. In this report, we studied the E protein topology from the new SARS-CoV-2 virus both in microsomal membranes and in mammalian cells. Experimental data reveal that E protein is a single-spanning membrane protein with the N-terminus being translocated across the membrane, while the C-terminus is exposed to the cytoplasmic side (Nt lum /Ct cyt ). The defined membrane protein topology of SARS-CoV-2 E protein may provide a useful framework to understand its interaction with other viral and ho…

Sensory systems sequentially extract increasingly complex features. ON and OFF pathways, for example, encode increases or decreases of a stimulus from a common input. This ON/OFF pathway split is thought to occur at individual synaptic connections through a sign-inverting synapse in one of the pathways. Here, we show that ON selectivity is a multisynaptic process in the Drosophila visual system. A pharmacogenetics approach demonstrates that both glutamatergic inhibition through GluClα and GABAergic inhibition through Rdl mediate ON responses. Although neurons postsynaptic to the glutamatergic ON pathway input L1 lose all responses in GluClα mutants, they are resistant to a cell-type-specifi…
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…
Researching Children’s Multiple Family Relations: Social Network Maps and Life-Lines as Methods
2015
Visual methods are reported to have certain advantages when conducting interviews on sensitive topics, such as intimate spaces, home-related ethical issues, and vulnerable families. In this article, we concentrate on two visual methods: social network maps and life-lines. In our research project on children’s well-being and emotional security in multiple family relations, we collected data by interviewing children and asking them to complete social network maps and life-lines. We discuss the suitability of these two visual methods for describing children’s close relationships with their family members and significant others. Combining these two methods during an interview process with child…
Gas Emissions From the Western Aleutians Volcanic Arc
2021
The Aleutian Arc is remote and highly active volcanically. Its 4,000 km extent from mainland Alaska to Russia’s Kamchatka peninsula hosts over 140 volcanic centers of which about 50 have erupted in historic times. We present data of volcanic gas samples and gas emission measurements obtained during an expedition to the western-most segment of the arc in September 2015 in order to extend the sparse knowledge on volatile emissions from this remote but volcanically active region. Some of the volcanoes investigated here have not been sampled for gases before this writing. Our data show that all volcanoes host high-temperature magmatic-hydrothermal systems and have gas discharges typical of volc…
A Low-Cost Smartphone Sensor-Based UV Camera for Volcanic SO2 Emission Measurements
2017
Recently, we reported on the development of low-cost ultraviolet (UV) cameras, based on the modification of sensors designed for the smartphone market. These units are built around modified Raspberry Pi cameras (PiCams; ≈USD 25), and usable system sensitivity was demonstrated in the UVA and UVB spectral regions, of relevance to a number of application areas. Here, we report on the first deployment of PiCam devices in one such field: UV remote sensing of sulphur dioxide emissions from volcanoes; such data provide important insights into magmatic processes and are applied in hazard assessments. In particular, we report on field trials on Mt. Etna, where the utility of these devices in quantif…
