Digital Games in Early Childhood: Broadening Definitions of Learning, Literacy, and Play

2017

Digital games attract children and young people with imaginary worlds, fascinating stories, and shared experiences with peers. They also can add children’s learning and motivation and offer a variety of new affordances to explore and play with. The pedagogical use of digital games has been found to potentially intensify a more critical use and understanding of varied forms of media. In this chapter, we will focus on analyzing the role of digital games in early childhood, especially from the perspectives of learning, literacy, and play. This chapter examines digital games as playing an essential role in young children’s overall technology experiences, particularly in the context of the socia…

Waveforms clustering and single-station location of microearthquake multiplets recorded in the northern Sicilian offshore region

2013

In 2009 December, the OBSLab-INGV (Istituto Nazionale di Geofisica e Vulcanologia) deployed an Ocean Bottom Seismometer with Hydrophone (OBS/H) near the epicentral area of the main shock of the Palermo seismic sequence of 2002. The monitoring activity had a total duration of about 8 months. During this experiment, the OBS/H recorded 247 very local microearthquakes, whose local magnitude is between -0.5 and 2.5 and TS - TP delay time between 0.2 and 5 s, almost all ofwhichwere undetected by the Italian National Seismic Network. This local microseismicity has been analysed using an innovative clustering technique that exploits the similarity between the waveforms generated by different events…

Sediment Transport and Hydrodynamic Parameters of Tsunami Waves Recorded in Onshore Geoarchives

2014

In regions with a short historical tsunami record, the assessment of long-term tsunami risk strongly depends on geological evidence of prehistoric events. Whereas dating tsunami deposits is already well established, magnitude assessment based on remaining sedimentary structures is still a major challenge. In this study, two approaches were applied to deduce transport processes and hydrodynamic parameters of tsunami events from onshore deposits found in the coastal plain of Ban Bang Sak, SW Thailand: (1) The maximum offshore sediment source was determined using granulometry, geochemistry, mineralogy and foraminifera of the tsunamites, and reference samples from various marine and terrestrial…

Speculation and lottery-like demand in cryptocurrency markets

2021

Abstract This is the first paper that explores lottery-like demand in cryptocurrency markets. Since recent research provides evidence that cryptocurrency returns appear to be short-memory processes, we modify Bali, Cakici and Whitelaw’s (2011) and Bali, Brown, Murray, and Tang’s (2017) MAX measure and employ a weekly forecast horizon and daily log-returns from the previous week to calculate the metric for our portfolio sorts. From an econometric point of view, this study proposes statistical tests that are robust to unknown dynamic dependency structures in the cryptocurrency data. Our results show that average raw and risk-adjusted return differences between cryptocurrencies in the lowest a…

Ei, bii, sii – vai jotain ihan muuta? Lukutaidon alkeet vientituotteeksi

2015

Jo yli 200 000 suomalaislasta on saanut tukea lukemaan oppimiseen Ekapelistä, tutkimustietoon pohjautuvasta lukutaidon alkeiden teknologia-avusteisesta oppimisympäristöstä. Ajatus lukutaitoon johdattelevasta tietokonepelistä syntyi jo vuosia sitten Jyväskylän yliopistossa tehdyn dysleksiatutkimuksen yhteydessä. Vaikka Ekapelin ideana olikin alun perin tukea niitä, joille lukemaan oppiminen tuottaa vaikeuksia, peli on havaittu hyväksi kenelle tahansa aloittelevalle lukijalle. Tästä syntyi ajatus tehdä pelistä uusia kieliversioita myös niille lapsille, joille lukutaito on isojen ponnistusten takana esimerkiksi heikon opetuksen, vieraan kielen tai yhteisön epäileväisten asenteiden takia. UNESC…

Heikkojen lukijoiden suoriutuminen luku- ja kirjoitustaitoa sekä niihin liittyviä taitoja arvioivissa tietokonetehtävissä neljännellä luokalla

2017

Tämän tutkimuksen tarkoituksena oli selvittää heikkojen lukijoiden suoriutumista luku- ja kirjoitustaitoa sekä niihin liittyviä taustataitoja arvioivissa tietokonetehtävissä neljännellä luokalla. Lisäksi selvitettiin mitkä tehtävät toimivat parhaiten lukutaidon arvioimisessa ja mielenkiinnon kohteena oli myös uusien tietokonepohjaisten ja perinteisten kynä-paperitehtävien vertailu. Tutkimuksen aineisto koostui 179 oppilaasta keskisuomalaisten peruskoulujen 4. luokilla. Lapset jaettiin Lukilassen sanalistan lukemistehtävässä suoriutumisen perusteella tavallisesti (N=156) ja heikosti (N=18) lukevien ryhmiin. Osallistujat tekivät 13 luku- ja kirjoitustaitoja sekä niihin liittyviä taustataitoja…

Ekfrasen som begivenhet

2021

Sammendrag Ekfrasebegrepet har vært gjenstand for mye diskusjon de siste tiårene. Denne artikkelen viser hvordan det har blitt lansert flere forslag til hvordan man kan legge bak seg en snever forståelse av møtet mellom tekst og bilde som en form for representasjon. Samtidig vises det hvordan løsningsforslagene virker sterkt fragmenterende og at de baserer seg på avgrensete perioder. I denne artikkelen lanseres begrepet «ekfrastisk begivenhet» som en alternativ formulering for å fange en bredere, kontekstuell forståelse av fenomenet. Samtidig innføres også begrepet «begivenhetshorisont» for å artikulere hvordan viktige institusjonelle og romlige premisser for ekfrasen har endret seg gjennom…

Personalization of Fast Conduction Purkinje System in Eikonal-Based Electrophysiological Models with Optical Mapping Data

2010

We present a pipeline for the personalization of model-based Purkinje fast conduction system using fast electrophysiological models and optical mapping data acquired from ex-vivo porcine hearts. The regional density of the Purkinje terminals as well as the latest endocardial activation time were the parameters personalized in an iterative procedure maximizing the similarity between the outcome of the electrophysiological simulations and measurements obtained from optical mapping data. We used a fast wave-front Eikonal-based electrophysiological model that generated the depolarization time maps that were subsequently compared with measurements at each iteration of the optimization stage. The…

A Banki–Michell turbine for in-line water supply systems

2017

The design of a novel Banki-Michell type turbine, to be located in existing water pipelines, is proposed. The turbine has a very efficient diffuser which allows the turbine to be compact and, most important, to have in-line flanges for minimal piping modifications at existing sites. This turbine combines a simple geometry with stable efficiency in a wide range of water discharges. The design procedure estimates the outer diameter of the impeller, its width and the geometry of the diffuser. A series of experimental tests has been carried out to measure the efficiency of the proposed turbine prototype. The turbine was tested in two different configurations, with and without rotational velocit…
