Heritability of Intraocular Pressure in Older Female Twins
2006
Purpose To examine the heritability of intraocular pressure (IOP) among older women not diagnosed as having glaucoma. Design Cross-sectional twin study. Participants 94 monozygotic (MZ) and 96 dizygotic (DZ) female twin pairs aged 63–76 years and not diagnosed as having glaucoma. Methods Intraocular pressure was measured using a noncontact tonometer. The contributions of genetic and environmental factors to individual differences in IOP were estimated by applying an independent pathway model to twin data. Main Outcome Measures Contribution of genetic and environmental effects to the variation in IOP among MZ and DZ twins. Results Mean IOP of the study population was 14.1 mmHg (± standard de…
Circular Economy and Value Creation: Sustainable Finance with a Real Options Approach
2021
This paper presents a methodological proposal that integrates the circular economy concept and financial valuation through real options analysis. The Value Hill model of a circular economy provides a representation of the course followed by the value of an asset. Specifically, after the primary use, the life of an asset may be extended by going through four phases: the 4R phases (Reuse, Refurbish, Remanufacture and Recycle). Financial valuation allows us to quantify value creation from firms’ asset circularity under uncertainty, modelled by binomial trees. Furthermore, the 4R phases are valued as real options by applying no-arbitrage opportunity arguments. The major contribution of this pap…
Anomalous and Not-So-Common Behavior in Common Ionic Liquids and Ionic Liquid-Containing Systems
2019
This work highlights unexpected, not so well known responses of ionic liquids and ionic liquid-containing systems, which are reported in a collective manner, as a short review. Examples include: (i) Minima in the temperature dependence of the isobaric thermal expansion coefficient of some ILs; (ii) Viscosity Minima in binary mixtures of IL + Molecular solvents; (iii) Anomalies in the surface tension within a family of ILs; (iv) The constancy among IL substitution of Cp/Vm at and around room temperature; (v) ILs as glass forming liquids; (vi) Alternate odd-even side alkyl chain length effects; (vii) Absolute negative pressures in ILs and IL-containing systems; (viii) Reversed-charged ionic l…
Mass Spectrometric Investigation of Noncovalent Complexation between a Tetratosylated Resorcarene and Alkyl Ammonium Ions
2004
Noncovalent complexation between tetratosylated tetraethyl resorcarene (1) and primary, secondary, and tertiary alkyl ammonium ions (mMe, dMe, tMe, mEt, dEt, tEt, dBu, and dHex) was studied by electrospray ionization Fourier transform ion cyclotron resonance (ESI-FTICR) mass spectrometry. Interactions of the noncovalent complexes were investigated by means of competition experiments, collision-induced dissociation (CID) experiments, ion-molecule reactions with tripropylamine and gas phase H/D-exchange reactions with deuteroammonia. Gas phase ion-molecule reactions gave especially valuable information about the structure and properties of the complexes. Resorcarene 1 formed relatively stable…
Effects of Biochar on Irrigation Management and Water Use Efficiency for Three Different Crops in a Desert Sandy Soil
2020
This paper aimed at investigating if the application of biochar (BC) to desert sand (DS) from the United Arab Emirates (UAE), characterized by a very poor soil-water retention (SWR) and by a very low value of the maximum water available for crops (AWmax), could positively affect soil water balance, by reducing the irrigation needs (VIRR) and improving the irrigation water use efficiency (IWUE) and the water use efficiency (WUE). The analysis was performed for three crops, i.e., wheat (Triticum aestivum), sorghum (Sorghum vulgare) and tomato (Lycopersicon esculentum). BC was applied to the DS at different fractions, fBC (fBC = 0, 0.091, 0.23 and 0.33). Drip irrigation was adopted as a highly…
Effects of Saline and Deficit Irrigation on Soil-Plant Water Status and Potato Crop Yield under the Semiarid Climate of Tunisia
2019
Water supplies have been decreasing in several semi-arid regions, and it is therefore necessary to adopt irrigation strategies aimed at maximizing water use efficiency. In this paper, the effects of saline and deficit irrigation on water use efficiency and on potato crop response, based on observations of soil and plant water status, were investigated. Experiments were carried out in Central Tunisia, by monitoring potato crop growth during two seasons in four distinct treatments (T1&ndash
Ethnocentrism Effects on Consumers’ Behavior during COVID-19 Pandemic
2021
The COVID-19 pandemic has upset everyone’s normal daily activities, generating psychiatric disorders and changing consumers’ preferences. Among others, the agri-food sector has experienced strong changes and, during the lockdown period, Italian consumers modified their purchasing habits in response to the fear and uncertainty generated by the spread of the virus. In order to find out the main consequences of the shock suffered during the period and to understand which factors have affected purchasing choices, an online survey was conducted on 286 Italian consumers. The results show that ethnocentrism has been the factor that most has influenced consumers’ behavior during the lockdown period…
Satisfacción laboral de los asalariados en España
2012
El objetivo de este trabajo es identificar los factores determinantes del nivel de satisfacción laboral de los asalariados en España, haciendo especial hincapié en las diferencias de género y de nacionalidad. Para ello, se estima un modelo de respuesta múltiple ordenada, utilizando los datos de la Encuesta de Calidad de Vida en el Trabajo, para el período que abarca desde 2006 a 2010. Los resultados obtenidos muestran que, después de controlar por las características personales y laborales de los asalariados, se obtiene un diferencial positivo en la satisfacción laboral en favor de las mujeres, mientras que no se evidencia la existencia de un efecto diferencial entre los asalariados nativos…
Justice et inégalités: un amendement à la théorie de John Rawls
1992
National audience; On se demande si les principes de justice de Rawls ne sont pas exagérément inégalitaires, malgré leur côté "juste". On examine donc ce qu'il advient de l'optimum de Rawls, le maximin, quand de l'aversion pour l'inégalité" apparaît. Le maximin consiste à se placer sur un certain point de la courbe d'efficience, en admettant une certaine dose d'inégalité, pourvu que l'on donne le maximum possible aux plus défavorisés. On tient compte d'externalités en reprenant la notion d'envie sous la forme d'une aversion pour l'inégalité, essentiellement de la part des plus défavorisés. On ne peut plus raisonner sur la courbe frontière des rémunérations possibles et on démontre la validi…
Is there a Market Value for Energy Performance in a Local Private Housing Market ? An efficiency analysis approach
2018
This paper aims to find evidence of a “green value” in a local housing market using notarial data on a small urban area in France. We use frontier functions, an original approach that departs from customary hedonistic regressions, to model housing market prices as a production set bordered by an efficiency frontier estimated by Data Envelopment Analysis (DEA). The paper tests if difference in prices (i.e. the distance from the frontier) can be explained by energy performance measured as a normalized categorical ascending kWh/m²/year grade (or Energy Performance Certificate -EPC). We show that there is significative evidence for energy performance's market value. The “Green Property Value” i…
