Hotel chain performance: a gravity-DEA approach

2011

Performance in business management can be measured in terms of competitiveness and efficiency. Generally speaking, competitiveness is a comparative concept of the ability of a firm, sub-sector or country to sell and supply goods and/or services in a given market, as measured by its market share. Particularly in competitive markets, efficiency plays a key role in determining this ability but it is not, by itself, sufficient. Indeed, while competitiveness has more to do with “pursuing the correct strategy” towards the conservation and/or increase of the market share, operational efficiency is mainly a measure of how well the firm, sub-sector or country under study processes inputs to achieve …

The euro impact on trade. Long run evidence with structural breaks

2012

In this paper we present new evidence on the euro effect on trade. We use a data set containing all bilateral combinations in a panel of 26 OECD countries during the period 1967-2008. From a methodological point of view, we implement a new generation of tests that allow solving some of the problems derived from the non-stationary nature of the data. To this aim we apply panel tests that account for the presence of cross-section dependence as well as discontinuities in the non-stationary panel data. We test for cointegration between the variables using panel cointegration tests, especially the ones proposed by Banerjee and Carrióni- Silvestre (2010). We also efficiently estimate the long-run…

Experimental study of the combined RES-based generators and electric storage systems for public buildings

2019

Abstract In the present paper, a new approach to the management of energy resources in the Research and Technology Centre of Energy (CRTEn -Tunisia) is proposed and evaluated by the monitoring of a PV installation realized for the cooperation project DE.DU.ENER.T, using renewable energy and economic criteria. The aim of this project is to improve energy efficiency order to minimize the electricity cost consumed at the CRTEn laboratory. According to the bills of electricity received, we noticed that there is a high consumption of electrical current. So, we targeted to install a photovoltaic field of 12KWc to reduce these bills by using the sustainable, green and clean sources. A theoretical …

Espungere e interpretare: a proposito dell’esodo di Ifigenia in Aulide

2014

L’articolo mostra che l’espunzione dell’esodo di Ifigenia in Aulide, su cui concordano quasi tutti gli editori, può comportare conseguenze decisive sul piano dell’interpretazione della tragedia. Infatti, in alcuni studi recenti, basati sull’edizione Kovacs (Loeb Classical Library, London 2002), che espunge la parte finale relativa al racconto del messaggero con la sostituzione animale, la morte di Ifigenia viene considerata la vera conclusione della tragedia. Da qui è derivata un’interpretazione in chiave politica del sacrificio, secondo la quale, conclusasi negativamente la guerra con Sparta e in assenza di una valida classe dirigente, la morte di un’innocente sarebbe necessaria alla reali…

EX-ANTE AND EX-POST MEASUREMENT OF EQUALITY OF OPPORTUNITY IN HEALTH: A NORMATIVE DECOMPOSITION

2013

This paper proposes and discusses two different approaches to the definition of inequality in health: the ex-ante and the ex-post approach. It proposes strategies for measuring inequality of opportunity in health based on the path-independent Atkinson equality index. The proposed methodology is illustrated using data from the British Household Panel Survey; the results suggest that in the period 2000–2005, at least one-third of the observed health equalities in the UK were equalities of opportunity.

Interest rate co-movements, global factors and the long end of the term spread

2012

The disconnect between rising short and low long interest rates has been a distinctive feature of the 2000s. Both research and policy circles have argued that international forces, such as global monetary policy (e.g. Rogoff, 2006); international business cycles (e.g. Borio and Filardo, 2007); or a global savings glut (e.g Bernanke, 2005) may be responsible. In this paper, we employ recent advances in panel data econometrics to document the disconnect and link it explicitly to the existence of a global latent factor that dominates the long end of the term spread for the recent period; the saving glut story emerges as the most likely contender for the global factor.

A Finite Difference Model of a PV-PCM System

2012

Abstract The performances of a photovoltaic panel (PV) are defined according to the “peak power” that identifies the maximum electric power supplied by the panel when it receives an insolation of 1 kW/m2 and the temperature of the cell is maintained at 25 °C. These conditions are only nominal since the solar radiation has a variable intensity and also the panel is subjected to thermal excursions; due to these reasons the real power efficiency of the panel is considerably lower than that obtainable in the nominal conditions. The study focused on assessing a method to reduce the peak temperatures of PV systems using Phase Change Materials (PCM). To this aim it was created a numerical model ca…
