An Italian input–output model for the assessment of energy and environmental benefits arising from retrofit actions of buildings
2013
Abstract The paper presents an energy and environmental extended input–output model combined with the life cycle assessment, applied to assess the energy and environmental benefits arising from the Italian policy of tax deduction for energy retrofit actions of buildings. The study allowed to assess the advantages due to the above policy, taking into account both direct and indirect energy saving and avoided CO 2 emissions obtained with the retrofit actions and indirect energy consumption and related CO 2 emissions due to the realization of the above actions. Moreover, the authors defined an original model to assess the indirect rebound effect caused by the energy saving actions. The obtaine…
Measurement of t ¯ t production with a veto on additional central jet activity in pp collisions at √ s = 7 TeV using the ATLAS detector
2012
A measurement of the jet activity in t[bar over t] events produced in proton–proton collisions at a centre-of-mass energy of 7 TeV is presented, using 2.05 fb[superscript −1] of integrated luminosity collected by the ATLAS detector at the Large Hadron Collider. The t[bar over t] events are selected in the dilepton decay channel with two identified b-jets from the top quark decays. Events are vetoed if they contain an additional jet with transverse momentum above a threshold in a central rapidity interval. The fraction of events surviving the jet veto is presented as a function of this threshold for four different central rapidity interval definitions. An alternate measurement is also perfor…
Precise measurement of the top quark mass in dilepton decays using optimized neutrino weighting
2016
We measure the top quark mass in dilepton final states of top-antitop events in proton-antiproton collisions at sqrt(s) = 1.96 TeV, using data corresponding to an integrated luminosity of 9.7 fb^-1 at the Fermilab Tevatron Collider. The analysis features a comprehensive optimization of the neutrino weighting method to minimize the statistical uncertainties. We also improve the calibration of jet energies using the calibration determined in top-antitop to lepton+jets events, which reduces the otherwise limiting systematic uncertainty from the jet energy scale. The measured top quark mass is mt = 173.32 +/- 1.36(stat) +/- 0.85(syst) GeV.
Pre-requisites of successful strategic electronic coordination : the moderation effect of the ownership mechanism of inter-organisational information…
2017
In this paper, we attempt to explain how the ownership mechanism of an interorganisational information system (IOS) may impact strategic information exchange (electronic coordination) induced by specific investments in the IOS. Recent research and practice show that heavy investments in IOSs demonstrate mixed results with respect to their impact on the electronic coordination. Consequently, the search of additional factors is needed to help and explain under what circumstances the IOS investments for strategic purposes become beneficial for the companies in a buyersupplier dyad. Transaction cost economics (TCE) and the hostage model are used as a framework for the research. 198 observations…

The design is based on a new modelling approach under the assumption of normbounded…
Measurement methodology for greenhouse gas emissions from storage of forest chips–A review
2015
Abstract Research on greenhouse gas emission related to solid biofuels has focused mainly on the emissions from end use and the production chain. GHG emissions from the storage of forest chips have not received much attention in recent literature. In order for EU emission reduction targets to be fully understood, emissions from solid biofuel storage needs to be better described. Usually emissions from chip piles have been modelled using studies from organic waste composting but these two materials can differ appreciably; for example the C/N-ratio and moisture content. Herein, previous studies on greenhouse gas emissions from forest chips piles during storage are reviewed. The objective is t…
The cost advantage of Sicilian wine farms
2013
This study presents the results of research carried out on a Sicilian wine farm in order to demonstrat e the economic convenience of the mechanized harvest. After the determination of the minimum optimal farm size that justifies the introduction of grape harve ster in the farm, it has been estimated production cost and the relative profitability of two wine grape cultiv ars (Chardonnay and Nero d’Avola), comparing three hypotheses of harvest: manual, with farm property g rape harvester and with rented grape harvester. The economic analysis shows that the introduction of th e grape harvester in the wine farm is justified in large sized farms. However, even in small farms the use o f rented g…
Location Theories and Business Location Decision: A Micro-Spatial Investigation of a Nonmetropolitan Area in Canada
2016
International audience; This paper draws on location theories to statistically identify the relationship between the location of individual business establishments and the characterization of their local economic environment. Taking a microspatial perspective, the paper develops indicators from distance-based measures (DBM) to serve as independent variables in a discrete choice model (DCM). Using a 2006 database of individual business establishments in the Lower-St-Lawrence region—a coherent, nonmetropolitan subsystem of cities in the province of Québec, Canada—we provide an empirical analysis of the determinants of individual establishments’ location decisions in relation to their main eco…
Review of factors influencing the success or failure of biocontrol: technical, industrial and socio-economic perspectives
2010
Communication orale au 11. IOBC-WPRS Meeting of the working group "Biological control of fungal and bacterial plant pathogens". Climate change: challenge or threat to biocontrol?, 2010/06/07-11 ; Graz (AUT).; International audience; Although their role in plant health management is still quite modest, ever increasing expectations are placed on biocontrol agents for the complementation or replacement of pesticide use. Despite decades of research and more than 12,000 scientific papers on biological control of plant diseases, little more than 14 microbe-based commercial products are presently registered for use against diseases in the European Union. Through a review of published scientific li…
