Creating Office Spaces in the Mediterranean. The importance of well-being, health and performance of office users
2018
Recent research has studied the influence of office buildings indoor environment quality (IEQ) on employees’ well-being, health and performance. However, it seems that it has not been explicitly explored what are the appropriate environmental conditions to different work patterns that coexist in these spaces. This paper presents results of an empirical research, based on the synchronized measurements of different IEQ parameters (i.e., noise, lighting and temperature), and well-being, health and performance of 71 employees in twelve office spaces in the Valencian Community along three periods, considering winter and summer conditions. Findings of the first winter period data, suggest the exi…
Smart and valued? ICT urban (transport) solutions in the city official communication
2022
To optimize the everyday functioning of a city, urban authorities can implement smart city tools and solutions. Mobility is a typical field associated with the concept of a smart city. It is interesting to take a closer look at the solutions applied through the information accessible on the official websites, while exploring, at the same time, the possibilities offered by new research tools. The main objective of this work is to establish the significance of the information and communication technologies (ICT) in the process of creating smart mobility in a smart city, based on the texts posted on official websites. Using the natural language processing (NLP) methods and tools offered by the…
Potential combined effects of maternal smoking and coffee intake on foetal death within the Danish National Birth Cohort
2018
Background: Several studies have linked coffee intake and smoking to foetal death, but a possible interaction between both exposures remains unknown.Methods: We studied, within the Danish National Birth Cohort, the potential interaction between smoking and coffee drinking while pregnant on the risk of foetal (early and late) death. The study included 90 086 pregnant women, with information about their smoking habit and coffee intake in early pregnancy, and several potential confounding factors. Interaction was studied by calculating both the hazard ratio (HR) in Cox's regression (linear and smoothed restricted cubic spline) and the interaction contrast ratio (ICR).Results: Women who neither…
The social significance of the Facebook Like button
2015
In this paper we study social aspects of using the Like button for purposes of impression management, identity construction, and maintenance of social ties online. On the theoretical level our investigation combines Goffman’s notion of face-work with concepts of social network analysis, shedding light on what we dub ‘nano-level’ interaction and sociality on social networking sites. Our data come from a 2013 classroom survey in which 26 Finnish university students were asked about their motives for and ways of using the Like button. Our results show that though the Like button was designed to allow users to express their positive evaluations of the contents of Facebook posts, comments, and p…
Détermination du taux de salaire réel et analyse néoclassique
1997
L'ambition des Néoclassiques est d'établir une loi scientifique de la répartition qu’ils expliquent essentiellement de deux façons. La première explication est fondée sur la productivité marginale des facteurs déterminée à la production. La seconde est fondée sur l'échange qui détermine la rémunérationdes facteurs ou leur « prix » sur le marché. Or, ces deux déterminations ne sont pas compatibles. La théorie marginaliste écarte d'emblée une grande partie de la réalité économique représentée par les rendements croissants et constants. Elle limite encore son champ en supposant que sur une quantité fixe d’un facteur on peut employer n’importe quelle quantité de facteur variable, hypothèse néce…
La non stationnarité dans les séries saisonnières. Application au tourisme tunisien
1998
The purpose of the paper is to specify the nature of the seasonal behaviors of tourist stay demand in Tunisia by using recent tools of monthly time series analysis. The available series (tourist expenditures, prices, guest nights, reception capacities,...) are analyzed with the classical theory of demand and the theory of supply induced demand. Empirical results show that these series are generated by non stationary processes which seasonality is stochastic and deterministic. The extent of the maximum likelihood method proposed by Lee (1992) for monthly data emphasizes unit roots and cointegration relationships at some seasonal frequencies. Error correction models are derived for endogenous…

I soffitti in legno e canne. conoscenza e tecniche di intervento per una manutenzione sostenibili
2014
This study aims to analyze the vaulted and having a flat surface wooden ceilings that in Italy as well as in the all Europe found a great diffusion from XVII century to the first half of XX century, qualifying in the more complex and representative examples the monumental buildings, and often supporting at the intrados an unique and irreplaceable decoration. We believe that the knowledge of materials and construction techniques used for the original creation of these wooden carpentries, which draw on the "rules of art", is fundamental to support technicians and the other restorers in choosing the most appropriate intervention, addressing to the use of "sustainable choices" that could promot…
I soffitti lignei dipinti e le strutture di copertura nella architettura religiosa della Sicilia barocca. Conoscenza e diagnosi per il progetto di re…
2009
Wooden ceilings characterize many baroque churches in Sicily and they have a particular meaning in the spatial conception of the architecture because of the false dome prospective painted on. For such a reason they are able to dominate the baroque architectural spatiality being a planar surface. Often forgotten and difficult to reach, the wooden painted ceilings represent an meaningful testimony of history and art but they are know asking for a conservation and maintenance attitude to start. The essay explain a method to design a conservation project without scaffolding and presents the software processing phases to develop in order to point out the degradation conditions through thermograp…
L'integrazione degli impianti ad aria con soffitti radianti nelle degenze ospedaliere: un caso studio per la valutazione delle condizioni di benesser…
2010
Nel presente lavoro vengono descritti i risultati di una ricerca sperimentale, condotta in periodo estivo, sulle prestazioni di comfort termico in degenze ospedaliere climatizzate mediante impianti ad aria primaria e sistemi radianti a soffitto. La ricerca sperimentale, sviluppata grazie alla collaborazione tra le Università di Ferrara, Bologna e Palermo ed una azienda produttrice di sistemi radianti a soffitto, è stata condotta all’interno di due stanze di degenza presso il reparto Maternità dell’Ospedale Maggiore di Bologna. La scelta del luogo è motivata dal fatto che è sempre maggiore l’attenzione della letteratura verso gli standard di comfort che devono essere garantiti nell’ambito os…
