Analyzing the Greek renewable energy sector: A Data Envelopment Analysis approach
(2012)This paper applies a bootstrapped Data Envelopment Analysis (DEA) formulation aiming to evaluate the financial performance of the firms operating in the Greek renewable energy sector. With the use of financial ratios in a ... -
Body fatness affects feed intake of sheep at a given body weight
(2006)In a 1-yr experiment, nutritional treatments were used to produce different combinations of BW and BCS in lambs. The experiment served to quantify the effects of BW and BCS on ADFI by sheep. Ewe lambs (n = 78) were assigned ... -
Crime and the effectiveness of public order spending in Greece: Policy implications of some persistent findings
(2013)Increasing crime rates invariably result in calls for more police protection which requires the allocation of additional scarce resources to policing and public order. In an environment of fiscal pressures, the effectiveness ... -
THE EFFECT OF ACCESS TO IMPROVED WATER SOURCES AND SANITATION ON ECONOMIC EFFICIENCY: THE CASE OF SUB-SAHARAN AFRICAN COUNTRIES
(2012)This paper evaluates the effect of access to improved water sources and sanitation on 41 sub-Saharan African (SSA) countries' economic efficiency and growth. For this reason data envelopment analysis (DEA), bootstrap ... -
Industry performance evaluation with the use of financial ratios: An application of bootstrapped DEA
(2012)In data envelopment analysis (DEA) context financial data/ratios have been used in order to produce a unified measure of performance metric. However, several scholars have indicated that the inclusion of financial ratios ... -
Influence of covering material and shading on the spectral distribution of light in greenhouses
(1999)The solar photon flux distribution was measured in the range from 400 to 1100 nm under a twin-span glasshouse and under the same glasshouse with blanked roof, external shading net and internal aluminized shade-screen. ... -
Magnetic colloidal superparticles of Co, Mn and Ni ferrite featured with comb-type and/or linear amphiphilic polyelectrolytes; NMR and MRI relaxometry
(2015)The ability to encapsulate hydrophobic ferrites in colloidal superparticle structures of an a-telechelic hexadecyl-functionalized poly(methacrylic acid) (C16H33-PMAA) polymer with a linear architecture was investigated and ... -
Measuring regional economic efficiency: the case of Greek prefectures
(2010)This paper, using Data Envelopment Analysis (DEA), measures for the first time the economic growth policies of the Greek prefectures. Based on the neoclassical model of growth it uses private and public investments and ... -
Modelling the effect of national culture on multinational banks' performance: A conditional robust nonparametric frontier analysis
(2011)Most of the efficiency studies of large multinational banks operating in different countries calculate banks' inefficiency levels without taking into account the environmental factors in which they are operating in. As a ... -
Regional sustainability efficiency index in Europe: an additive two-stage DEA approach
(2015)In this paper we apply a relational additive two-stage data envelopment analysis model in order to create sustainability efficiency indices for European regions. The sustainability efficiency indices are decomposed into ... -
A review of PET normalization: striving for count rate uniformity
(2013)The advent of PET instrumentation signaled the beginning of a new perspective in nuclear medicine diagnostic imaging. PET systems rely on several corrections that must be applied in order to establish accurate and reliable ... -
Toward a new practical energy evaluation system for dairy cows
(2009)Energy evaluation systems translate an animal's net energy (NE) requirements into feed metabolisable energy requirements (MER). The Feed into Milk (FiM) project (Agnew RE, Yan T, France J, Kebreab E and Thomas C 2004. ... -
Transmission of Potato virus Y in tobacco plants by Myzus persicae nicotianae and M-persicae s.str
(2006)The transmission efficiency of Potato virus Y-N (PVYN) from and to tobacco plants by Myzus persicae nicotianae, a tobacco specialist, and M. persicae s.str. (Hemiptera: Aphididae), a generalist, was evaluated. In direct ... -
Yield performance at three nitrogen rates of a set of honeycomb vs traditional pedigree selected bread wheat varieties
(2003)The honeycomb nil interplant competition selection procedure has been proposed as effective breeding methodology in developing high yielding and broadly adapted wheat varieties. The objective of this research were to (i) ...
