Relations between representational consistency, conceptual understanding of the force concept, and scientific reasoning

2012

Previous physics education research has raised the question of “hidden variables” behind students’ success in learning certain concepts. In the context of the force concept, it has been suggested that students’ reasoning ability is one such variable. Strong positive correlations between students’ preinstruction scores for reasoning ability (measured by Lawson’s Classroom Test of Scientific Reasoning) and their learning of forces [measured by the Force Concept Inventory (FCI)] have been reported in high school and university introductory courses. However, there is no published research concerning the relation between students’ ability to interpret multiple representations consistently (i.e.,…

A model of degassing for Stromboli volcano

2010

International audience; A better understanding of degassing processes at open-vent basaltic volcanoes requires collection of new datasets of H2O–CO2–SO2 volcanic gas plume compositions, which acquisition has long been hampered by technical limitations. Here, we use the MultiGAS technique to provide the best-documented record of gas plume discharges from Stromboli volcano to date. We show that Stromboli's gases are dominated by H2O (48–98 mol%; mean, 80%), and by CO2 (2–50 mol%; mean, 17%) and SO2 (0.2–14 mol%; mean, 3%). The significant temporal variability in our dataset reflects the dynamic nature of degassing process during Strombolian activity; which we explore by interpreting our gas m…

Lidar detection of carbon dioxide in volcanic plumes

2015

Volcanic gases give information on magmatic processes. In particular, anomalous releases of carbon dioxide precede volcanic eruptions. Up to now, this gas has been measured in volcanic plumes with conventional measurements that imply the severe risks of local sampling and can last many hours. For these reasons and for the great advantages of laser sensing, the thorough development of volcanic lidar has been undertaken at the Diagnostics and Metrology Laboratory (UTAPRAD-DIM) of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA). In fact, lidar profiling allows one to scan remotely volcanic plumes in a fast and continuous way, and with high s…

Electrical conductivity of glass fiber-reinforced plastic with nanomodified matrix for damage diagnostic

2021

The electrical conductivity of glass fiber-reinforced plastic (GFRP) with epoxy matrix modified by multiwall carbon nanotubes (MWCNT) was studied. The electrical conductivity of nanomodified lamina and multi-layered GFRP was investigated on several levels using a structural approach. Components of the electrical conductivity tensor for unidirectional-reinforced monolayer were calculated similarly as in micromechanics using the conductivity of the nanomodified matrix. The electrical conductivity of multilayer composite was calculated using laminate theory and compared with values measured experimentally for various fiber orientation angles. Calculated and experimental data were in good agree…

Researcher roles in collaborative governance interventions

2023

While societies are facing complex problems involving multiple stakeholders and interdependencies, interest in collaborative governance as a potential solution is rising. Research-based interventions in policy, planning, and management processes have been introduced to test different approaches and tools for collaboration. The nature of these processes, tools, and approaches varies substantially, as do researchers’ cultures of making contributions to and in collaboration with society. This paper outlines the various possibilities and means for researchers to intervene in and explore steps towards collaborative governance. It utilises literature-based descriptions of potential roles for rese…

The Emotion Detectives Game: Supporting the Social-emotional Competence of Young Children

2017

The potential of digital games to enhance learning in different areas of child development has drawn increasing interest amid growing concern about children’s emotional well-being, social-emotional difficulties, and problem behaviors alongside diminishing economic resources for intervention and habilitation. However, digital games designed to promote social-emotional competence are surprisingly scarce. In this chapter, we explore children’s use of the digital game Emotion Detectives (ED), designed to promote children’s acquisition of emotional knowledge skills (e.g., recognizing, appreciating, and understanding emotions and their expressions), prosocial behaviors (e.g., helping, sharing, co…

Huoli kansakunnan tulevaisuudesta : diskurssianalyyttinen tutkimus Venäjän väestöpoliittisista muutoksista vuosina 2000-2010

2011

Pro gradu -tutkielmani käsittelee Venäjän valtionjohdon esittämiä väestöpoliittisia kannanottoja vuosina 2000-2010. Tutkimusaihe on relevantti ensinnäkin ajankohtaisuutensa vuoksi, sillä tutkimuksen kattamina vuosina julkisesti kannettu huoli väestön tilasta eli alhaisesta syntyvyydestä yhdistettynä korkeaan kuolleisuuteen on kärjistynyt. Tänä aikana toteutettiin laajoja väestöpoliittisia toimenpiteitä tilanteen parantamiseksi. Toiseksi aiheen relevanssi johtuu sen moniulotteisuudesta, sillä se herättää mm. perhettä, sukupuolta, seksuaalisuutta, kansantaloutta ja kansan tulevaisuutta koskevia kysymyksiä. Keskittymistä nimenomaan valtionjohdon puheisiin puoltaa yhtäältä se, että keskustelun …

Acompañamiento social en clave local. Evaluación de una metodología de intervención con los y las ACL en medio abierto de la provincia de Valencia

2021

En las nuevas sociedades, el delito forma parte del espacio cotidiano, trascendiendo los antiguos límites de la exclusión y de jóvenes con mayor dificultad de inserción social. Una extensión del riesgo que afecta y vulnera a los y las jóvenes, y que ha contribuido en la diversificación de los y las adolescentes en conflicto con la ley, coexistiendo dos perfiles diferenciados socialmente, los procedentes de contextos de exclusión y los adaptados socialmente; exigiendo una reflexión sobre la intervención llevada a cabo con ellos. En el presente trabajo doctoral se analiza la intervención realizada desde el medio abierto con estos adolescentes en conflicto con la ley en la provincia de Valenci…
