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…

Procedures for study of teaching practices. Literature Review

2012

Interest in studying teaching practices has increased, because of the need to evaluate teachers and dissatisfaction with the usual ways of doing it. Recent approaches with Value-Added Models, based on students’ results on achievement tests do not seem satisfactory. The article is based on a review of literature and classifies the approaches to practices in three groups: instruments based on information given by teachers; observation protocols; and approaches based on the analysis of products of the practices. Specific tools are described and advantages and disadvantages of the three approaches are discussed. El interés por las prácticas docentes ha aumentado, en parte por la necesidad de ev…

Postural entrainment by vocal effort in singing and speech

2009

This study assesses the interaction of the postural control system and the production of expressive vocal behavior during speech and singing. In particular, we focus on the head, whose motions have been implicated for both postural control and spoken language production. How does head motion behavior simultaneously serve posture control and linguistic communication during vocalization? This study examines the interaction of these two subsystems by measuring the effects of different levels of vocal effort (loudness) on speech and singing. We show that as vocalizations becomes louder the correspondence between measures of head motion and speech acoustics become less complex and better coordin…

Nullità va cercando, ch’è sí cara come sa chi per lei legittimità rifiuta: spunti su alcuni comportamenti attizi tra amministrazione e giurisdizione

2020

The work focuses on the qualification, jointly with the procedural consequences on the relevant trial, of the regime of some administrative decision as to whether they are total irrelevant in law or rather they do have some sort of efficacy

Emission of Bromine and Iodine from Mt. Etna volcano

2005

Constraining fluxes of volcanic bromine and iodine to the atmosphere is important given the significant role these species play in ozone depletion. However, very few such measurements have been made hitherto, such that global volcanic fluxes are poorly constrained. Here we extend the data set of volcanic Br and I degassing by reporting the first measurements of bromine and iodine emissions from Mount Etna. These data were obtained using filter packs and contemporaneous ultraviolet spectroscopic SO2 flux measurements, resulting in time-averaged emission rates of 0.7 kt yr(-1) and 0.01 kt yr(-1) for Br and I, respectively, from April to October 2004, from which we estimate global Br and I flu…

Sysmä Community Currency: An Analysis of its Success from the Perspectives of Purposes, Stakeholders and Promotion

2019

Artikkeli on tapaustutkimus paikallisrahajärjestelmästä, jota kokeiltiin äskettäin maalaisympäristössä Sysmän kunnassa. Paikallisraha on yksi innovaatiivisista aloitteista, joita kunta on tehnyt tällä vuosituhannella torjuakseen jo 1960-luvulta alkaen käynnissä ollutta väestökatoa. Tässä artikkelissa tutkitaan paikallisrahan käynnistysvaihetta siihen sisältyneiden ristiriitojen näkökulmasta. Artikkelissa todetaan, että järjestelmä kärsi epäselvästä tavoitteenasettelusta, ja että eri osallisilla oli tavoittesta vaihtelevia ja ristiriitaisia käsityksiä. Paikallisrahan sosiaalista hyväksyntää heikensivät päätös rajoittaa rahaa vastaanottavien yritysten joukko kunnassa kirjoilla oleviin yrityks…

Wage Effects of Firm Size : Evidence from Linked Employer-Employee Panel

2017

This study explores the relationship between wages and firm size using large registered data and different identification strategies. We found that the effect of firm size on wages is negligible when worker and firm characteristics are accounted for. The findings are robust across identification strategies and numerous covariates. The findings are also consistent with the view that coordinated wage-setting systems narrow wage distributions. peerReviewed

Waste heat recovery from a marine waste incinerator using a thermoelectric generator

2012

Published version of an article published in the journal: Journal of Electronic Materials. Also available from the publisher at: http://dx.doi.org/10.1007/s11664-012-2009-6 A marine waste incinerator has been evaluated for waste heat harvesting using thermoelectric generators (TEG). The application has been evaluated using mathematical modeling to optimize the heat exchanger and some vital design parameters of the TEG. The calculation shows that it is possible to extract 58 kW el at a price of 6.6 US$/W from an 850-kW th incinerator when optimizing for maximum power. However, minimizing the cost, it is possible to get 25 kW el at a price of 2.5 US$/W. A trade-off between the two targets lea…
