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…
Building sustainable contextual ambidexterity through routines: a case study from information technology firms
2020
The purpose of this paper is to explain the role that routines play in achieving sustainable organisational ambidexterity in information technology (IT) firms. Our exploratory analysis of four case studies reveals the key importance of routines in setting the context for sustainable ambidexterity. Companies build up contextual ambidexterity through routines derived from normalization of processes, normalization of skills, and normalization of results. The findings of the study show that routines support IT professionals to decide whether to exploit or explore in each particular case. Firstly, the enabling character of explicit routines as a result of the normalisation of work processes and …
Propozycja wdrożenia koncepcji „lean construction” opartej na znormalizowanych systemach zarządzania jakością w organizacjach branży budowlanej= The …
2020
W niniejszym artykule omówiono wyniki badań dotyczące dojrzałości wdrożonych systemów zarządzania jakością w wybranych organizacjach branży budowlanej, pod kątem możliwości wdrożenia koncepcji „lean construction”. Wiele badań wskazuje na potencjalne korzyści, jakie mogą uzyskać organizacje w wyniku zastosowania zasad „lean”, np. obniżenie kosztów, zmniejszenie czasu realizacji budowy, zmniejszenie marnotrawstwa. Celem niniejszego artykułu jest przedstawienie propozycji [głównych zadań] wdrożenia koncepcji „lean”, opartych na znormalizowanych systemach zarządzania jakością, w organizacjach branży budowlanej. W badaniu wykorzystano analizę dokumentacji, wywiady, metodę samooceny zgodnej z ISO…

Diseño y Validación de un Instrumento para Evaluar la Justicia Social Percibida en la Escuela
2022
Tradicionalmente la evaluación educativa se ha tomado como recurso para la mejora de la calidad, basándose principalmente en el éxito académico. Investigaciones recientes valoran, además, estudiar la percepción que tiene el alumnado sobre otros aspectos personales, familiares, sociales y escolares –del alumnado–. La finalidad de la presente investigación es diseñar y validar el instrumento para evaluar la Justicia Social Percibida en Educación (JSP-E) por parte del alumnado de educación primaria y secundaria, en todas sus fases, desde su definición, la operativización de esta en dimensiones, indicadores e ítems. Mediante el enfoque metodológico mixto, combinando las perspectivas cualitativa…
