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…
Research and Development Expenditures and Economic Growth in the EU: A Panel Data Analysis
2016
Abstract The main aim of the paper is to investigate the empirical relationship between research and development (R&D) expenditures and economic growth in the European Union member states in the period of 2000–2013. The empirical analysis is based on panel data regressions. The estimated model is the production function type standard growth model extended with R&D stock variable. The results show a statistically significant impact of R&D expenditures on the economic growth in the EU countries. The significance for R&D coefficient remains robust to different sub-periods, but the level of significance decreases as a sub-sample of new EU countries was considered.
Explaining Ethiopia’s Growth Acceleration—The Role of Infrastructure and Macroeconomic Policy
2017
Summary Ethiopia has experienced an impressive growth acceleration over the past decade. This was achieved on the back of an economic strategy emphasizing public infrastructure investment supported by heterodox macro-financial policies. This paper identifies the drivers of Ethiopia’s recent growth episode and examines the extent to which they were typical or unique. It combines country-specific information with the results of a cross-country panel regression model. We find that Ethiopia’s growth is explained well by factors correlating with growth in a broad range of countries in recent decades, including public infrastructure investment, restrained government consumption, and a conducive e…
Innovation and R&D spillover effects in Spanish regions: A spatial approach
2007
Abstract This paper analyses the spatial patterns of innovation, its regional interdependencies and evolution, as well as its role in determining local innovation in Spanish regions. Results indicate the suitability of a trade-based regional proximity when considering spatial spillovers in innovation. In this context, not only local capacity is relevant in determining domestic innovation, but also spatial innovation spillovers, which result mainly from efforts in both higher education and public administration. Moreover, a minimum level of regional development is required to improve the effectiveness of R&D policies. Therefore, it is necessary for R&D policies to act in combination with oth…
Panel Discussion on Data Analysis Trends in X-Ray and Gamma-Ray Astronomy
1986
ZIMMERMANN: Let me begin the panel discussion on Data Analysis Trends in X-ray and Gamma-ray astronomy by first introducing the panel members. These are from the left to the right: Roland Diehl, Ethan Schreier, Rosolino Buccheri, Livio Scarsi, Jean-Marc Chassery and Wolfgang Voges. With the exception of Jean-Marc Chassery, who is an expert on image processing and statistical analysis, all the others have longer experience in the X-ray and Gamma-ray fields. May I ask the speakers to keep their contributions to not more than five minutes, in order to allow ample room for discussion with the audience.
Unemployment Hysteresis in Transition Countries: Evidence using Stationarity Panel Tests with Breaks
2008
The authors test hysteresis versus the natural rate hypothesis in unemployment using panel data for transition countries covering the period 1991:1–2003:11.The advantages of the stationarity tests applied is that they exploit the cross-section variations of the series and, additionally, allow for a different number of endogenous breakpoints in the unemployment series. They do not impose independence on the panel members, so that the critical values are simulated based on their specific panel sizes and time periods. The findings stress the importance of accounting for exogenous shocks in the series and give support to the shifting natural-rate hypothesis of unemployment for all the countries…
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 …

Allergy, 2009; 64:1427-1443] is the result of a consensus reached during a panel discussion at the 3rd International Consensus Meeting on Urticaria, Urticaria 2008, a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the EU-funded network of excellence, the Global Allergy and Asthma European Network (GA(2)LEN), the European Dermatology Forum (EDF) and the World Allergy Organ…
Outdoor flat-panel membrane photobioreactor to treat the effluent of an anaerobic membrane bioreactor. Influence of operating, design, and environmen…
2018
[EN] As microalgae have the ability to simultaneously remove nutrients from wastewater streams while producing valuable biomass, microalgae-based wastewater treatment is a win-win strategy. Although recent advances have been made in this field in lab conditions, the transition to outdoor conditions on an industrial scale must be further investigated. In this work an outdoor pilot-scale membrane photobioreactor plant was operated for tertiary sewage treatment. The effects of different parameters on microalgae performance were studied including: temperature, light irradiance (solar and artificial irradiance), hydraulic retention time (HRT), biomass retention time (BRT), air sparging system an…
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…
