Drivers and barriers to online airline ticket purchasing
2009
Although online sales of airline tickets are growing, many travellers are still reluctant to use the web as a purchase channel. Given the cost advantages of online sales for airlines, it is useful for them to know the main drivers and barriers affecting the use of the Internet to purchase tickets. This study analyses the influence of risk, perceived usefulness and perceived ease of use on the airline ticket online purchase intention. The results of a survey show that perceived purchase risk and perceived usefulness exercise a direct influence on airline ticket purchasing intentions, while perceived ease of use has an indirect influence through perceived usefulness. Psychological risk, perfo…
Nomograph for rapid technical and economic assessment of solar thermal systems for DHW production
2012
Abstract Different types of tools, software and empirical methods to size and assess the performance of solar thermal systems are available today. A quick and easy-to-use graphical tool is proposed here. It is based on a single diagram, called a nomograph, which embeds technical and economic information, allowing the optimisation of the size and performance of a solar thermal system starting from the main input parameters, such as the specific costs of the system and the auxiliary fuel. The optimal surfaces are calculated as a function of the fuel cost through several regressions made on data from the application of the F-Chart method for a set of system configurations. The authors have fou…
Le arti performative nel mondo di Internet e dell’Interaction Design: l’avventura tecno-artistica di Kònic Thtr di Barcellona
2017
Che cos’è internet? Cosa rappresenta e come cambia quando s’intreccia alle arti performative, da sempre legate a uno spazio di condivisione fisico e reale? Come si libera dal suo livello strettamente tecnologico - permettere la comunicazione tra individui a distanza - per divenire tecnica mediata, medium, linguaggio metaforico? Attraverso l’analisi di alcune performance del gruppo di Barcellona Kònic Thtr si cercherà di tracciare quale sia oggi la relazione e in particolare il grado d’ibridazione tra internet e le arti performative. What is the internet? What does it represent and how does it change when it intertwines with the performing arts, which have always been linked to a physical an…
Experimental Evidence on the Thermal Performance of Opaque Surfaces in Mediterranean Climate
2013
The thermal insulation of buildings, intended as wrap feature which determines the dispersion of heat, the reference parameter is necessary to contain the thermal losses during the winter season. The transmittance of the opaque components, used as an indicator of the energy quality of a casing, together with the overall coefficient of dispersion, represents a proper descriptor of the behavior during the heating season. However, if a strong insulation in winter conditions brings only positive effects, the same cannot be said for the summer conditions. A high value of the insulation in the casing is convenient only when the gains free, either in the form of solar contribution that of endogeno…

INNOVAZIONE DEI MATERIALI NATURALI: TERRA E NANOTUBI DI ARGILLA PER UNA SFIDA SOSTENIBILE
2019
All’interno del dibattito culturale che vede la questione ambientale come prioritaria e con riferimento a studi e ricerche che negli ultimi anni hanno promosso materiali compositi a base di terra cruda, gli Autori, consapevoli della necessità che il rapporto fra Progetto e Materia debba assumere una nuova centralità supportato dalle specificità della Tecnologia dell’Architettura, illustrano le risultanze di una sperimentazione che ha l’obiettivo di migliorare le prestazioni della terra cruda con l’apporto delle nanotecnologie, sviluppando un ‘nuovo materiale’ con una ridotta embodied energy e una ridotta quantità di emissioni di CO2 in atmosfera.

Participation and performance trends in multistage ultramarathons--the 'Marathon des Sables' 2003-2012
2012
International audience; BackgroundThe purpose of this study was to investigate participation and performance changes in the multistage ultramarathon 'Marathon des Sables' from 2003 to 2012.MethodsParticipation and performance trends in the four- or six-stage running event covering approximately 250 km were analyzed with special emphasis on the nationality and age of the athletes. The relations between gender, age, and nationality of finishers and performance were investigated using regression analyses and analysis of variance.ResultsBetween 2003 and 2012, a number of 7,275 athletes with 938 women (12.9%) and 6,337 men (87.1%) finished the Marathon des Sables. The finisher rate in both women…
De la performance musicale dans la Guyane traditionnelle : expression cognitive singulière d?une musique-verbe
2021
Guianese culture and traditional music, here evoked, are various. It is more a transcultural process that, along centuries, gave an original result born in the Americas, in Guiana in this case. It is a form of refoundation, of recreation of cultures and new human beings generally called Creoles. The musical performance, that I study here, is the echo of social and cultural space of this reformulation of thought, life, and conception of the world. It is, as well, a mean of transposition and transformation of the values issued of diverse sources and categories. It is in no way a second-rate cultural practice, as it is the place where were born philosophies and actions for common life as well …
