The role of immigrants' self identity in effective integration process into Finland
2016
The purpose of this research is to study the role of immigrants’ identity in the process of effective integration into Finland. The research questions of the study explore (a) individual perceptions of self identity and effective integration into the host society from immigrants’ perspectives, (b) the impact of the integration process on immigrants’ self identity and (c) the identity changes of immigrants during the process of integration into the host society. Semi-structured in-depth interviews were conducted with six participants in Jyväskylä, Finland in order to best capture immigrants’ diverse life experiences reflecting identity issues during the integration process into the host soci…

Calcium silicate hydrates: Solid and liquid phase composition
2015
© 2015 Elsevier Ltd. This paper presents a review on the relationship between the composition the structure and the solution in which calcium silicate hydrate (C S H) is equilibrated. The silica chain length in C S H increases with the silicon concentration and the calcium content in the interlayer space with the calcium concentrations. Sodium and potassium are taken up in the interlayer space preferentially at low calcium concentrations and thus by low Ca/Si C S H. Aluminium uptake in C S H increases strongly at higher aluminium concentrations in the solution. At low Ca/Si aluminium substitutes silica in the bridging position at Ca/Si. > 1 aluminium is bound in TAH. Recently developed ther…
Intelaiature lignee leggere quale presidio antisismico nell'architettura tradizionale di area mediterranea
2017
L’accresciuta attenzione nei confronti degli aspetti costruttivi dell’edificato storico, associata all’analisi delle tecniche attraverso la ricerca archivistica, ma ancor più gli interventi di restauro e recupero che punteggiano i centri storici per iniziativa pubblica e privata consentono di ritrovare -nascoste anche all’occhio attento che le sa riconoscere- le intelaiature a graticcio ligneo: teatri ad intera struttura lignea, la configurazione interna di saloni ed ambienti di rappresentanza di palazzi nobiliari, chiese, conventi o monasteri ed anche l’edilizia diffusa che definiremmo “di base” testimoniano la capillare applica-zione del sistema costruttivo, con invarianti ed originalità …
Action-Depicting Gestures and Morphosyntax: The Function of Gesture-Speech Alignment in the Conversational Turn
2021
The current study examines the role of action-depicting gestures in conversational turns by focusing on their semantic characteristics and temporal position in relation to their verbal affiliates (action verbs or more complex verb phrases). The data are video recordings of naturally occurring interactions in multilingual construction sites in Norway. The analysis distinguishes two modes of action depiction: generic depictions, which represent the action as a general type, and contextualized depictions, which in addition include deictic references to the spatio-material environment or iconic representations of the specific manner of action performance. These two modes typically occupy differ…
Can noncomplementarity of agency lead to successful problem solving? A case study on students’ interpersonal behaviors in mathematical problem-solvin…
2022
In student collaboration, purposeful peer interaction crucial for success on the task. Such collaboration requires adequate and purposeful student agency. Theoretically, the between-individual complementarity of agency be-haviors enhances purposeful interaction. However, the level of agency of group members can disrupt the collaborative interactions. We conducted a case study of collaborative mathematical problem solving, where one student's behaviors of noncomplementary agency characterized the group interaction. We examined the video recording of the group by continuous quantitative coding of students' agency behaviors and segmented the interaction process into four phases. We analyzed qu…
Examining the critical factors that influence the success of construction and demolition waste reverse logistics operations
2022
The reverse logistics (RL) performance of construction and demolition waste (C&DW) differs significantly between countries. Although some countries are successfully circular, other countries are still far behind; with C&DW being largely directed to landfills or being illegally dumped. There is a lack of guidelines on the requirements for transitioning countries towards C&DW diversion, and little attention has been given to the factors that influence the success of C&DW RL and increased circularity. This study aims to develop a framework that helps in structuring and assessing the success of C&DW RL on a regional level and serves as a guide for transitioning developing co…
Power Production from Produced Waters via Reverse Electrodialysis: A Preliminary Assessment
2022
Wastewaters generated by crude oil extraction processes, called “produced waters” (PWs), are complex solutions that contain organic compounds, mainly hydrocarbons, and often exhibit high salinity. The large amounts of PWs represent a global issue because of their environmental impact. An approach widely used in the oil industry is the reinjection of this wastewater into the extraction wells after a suitable treatment. The high salt concentration of such solutions may be used in salinity gradient technologies to produce green electricity. Among these technologies, reverse electrodialysis (RED) is one of the most promising. In this work, the application of RED for energy generatio…
Solai ad orditura metallica. Per una storia della costruzione
2016
Sommario: Il saggio approfondisce gli aspetti storici e costruttivi dei solai ad orditura metallica dalla fine del XVIII secolo all’ultima guerra. Dopo una parte generale in cui vengono delineate le motivazioni e le fasi iniziali dell’uso dei materiali ferrosi in edilizia, si traccia ed analizza una serie di linee evolutive della trave metallica, fino al raggiungimento della sezione a doppio T che, a pieno titolo, si considera il punto di arrivo della ricerca sulla forma più conveniente per evidenti motivi di efficienza statica, pur coi successivi affinamenti nella produzione, nel calcolo e nella messa in opera. Si è ipotizzata l’evoluzione attraverso le strade della combinazione legno-ferr…
