On the dynamics of eco-efficiency performance in the European Union

2016

This paper evaluates the evolution of environmental performance in the context of the European Union (EU), over the period 1993–2010. The context is particularly relevant, due to the traditionally high concerns of the EU about these issues, which has triggered off several initiatives and regulations on environmental protection. In this setting, we conduct a two-stage analysis which develops environmental performance indicators in the first stage for each pair country-year, and evaluates its evolution in the second. More specifically, in the first stage we estimate specific efficiencies for three air-pollutants (CO2e, SO2, NOx), along with an eco-efficiency indicator, for which we use the sl…

Uomini e technai nell'ambiente: tra Arie, acque, luoghi e il Prometeo incatenato

2021

Al centro dell'attenzione di questo studio è la relazione tra uomini e ambiente così come delineata nello scritto ippocratico Arie, acque, luoghi. In effetti, la valutazione di alcuni termini chiave presenti nell'opera ippocratica permette di individuare una relazione complessa, basata sulla reciproca osmosi e interazione tra l'essere umano e l'ambiente in cui vive, una relazione segnata da una terminologia che ne mette in luce il rapporto di somiglianza e di adattamento reciproco. Una particolare riflessione, in tal senso, merita la parte conclusiva del trattato ippocratico (considerato qui come unitario), in cui è descritta l'attitudine sociale (ethos) dell'essere umano, relativamente più…

Ancient proteins resolve the evolutionary history of Darwin's South American ungulates.

2015

No large group of recently extinct placental mammals remains as evolutionarily cryptic as the approximately 280 genera grouped as 'South American native ungulates'. To Charles Darwin, who first collected their remains, they included perhaps the 'strangest animal[s] ever discovered'. Today, much like 180 years ago, it is no clearer whether they had one origin or several, arose before or after the Cretaceous/Palaeogene transition 66.2 million years ago, or are more likely to belong with the elephants and sirenians of superorder Afrotheria than with the euungulates (cattle, horses, and allies) of superorder Laurasiatheria. Morphology-based analyses have proved unconvincing because convergences…

Efecto de intervenciones de psicología positiva y ejercicio físico en el bienestar y malestar psicológico de estudiantes universitarios

2019

Resumen El propósito de este estudio fue analizar el efecto de intervenciones de Psicología positiva y de ejercicio físico sobre indicadores de bienestar y malestar psicológico en estudiantes universitarios costarricenses. Se realizó una investigación cuasiexperimental, de diseño factorial (4 x 2) con mediciones pre y post, en el que 233 estudiantes universitarios (18.97 ± 2.18 años, 135 mujeres, 98 hombres) se vieron expuestos a una de cuatro diferentes condiciones: intervenciones de psicología positiva (PP), intervenciones de ejercicio físico (E), intervenciones combinadas de PP y E y control (C). Se midieron indicadores de bienestar y malestar psicológico. Las intervenciones de Psicologí…

Platinum and rhodium in wine samples by using voltammetric techniques

2017

For the first time, the concentrations of Pt and Rh in 42 different alcoholic beverages (white and red wines, vodka and brandy) produced in Italy, Malta and Gozo were investigated. Only the voltammetric techniques, in particular, differential Pulse Voltammetry (DPV/a) and Adsorptive Stripping Voltammetry (AdSV) were used for the determination of Pt and Rh respectively. Accuracy was tested with standard addition method and recoveries ranged from 90% to 98%. In analyzed wine samples, Pt and Rh concentrations are in the ranges from 3 to 470 μg L− 1and from 0.0006 to 0.36 μg L− 1respectively. We found a Pt/Rh ratios ranged from 37 to 180,000, in quite disagreement with the ratio in …

Assessment of polycyclic aromatic hydrocarbons (PAHs) in soil of a Natural Reserve (Isola delle Femmine) (Italy) located in front of a plant for the …

2009

Isola delle Femmine Natural Reserve is a very little isle about 15 km from the centre of Palermo, in front of a plant for the production of cement and about 600 m from coast. In the present research, profiles soil PAHs were obtained for 16 sites within the reserve and for 8 stations on the rural soil taken as reference. summation Sigma PAHs, in the soil of investigated area, ranged from 35 to 545 microg/kg. With the aim to find the origin of PAHs in the soil of Isola delle Femmine, we compare the distribution of single analytes in the investigated area with those of the reference rural area (Monte Raffo Rosso), with those of atmospheric urban particulate collected at Palermo along with repo…

L’uso insostenibile delle risorse ha prodotto la degradazione ambientale, l’erosione del suolo, la desertificazione, la deforestazione, la perdita di biodiversità, i cambiamenti climatici, senza che la povertà e l’accesso ineguale alle risorse venisse scalfita. Le azioni che compiono le persone e le loro scelte hanno un impatto diretto e indiretto sull’ambiente e sul benessere personale e collettivo.

Residential Exposure to Outdoor Air Pollution during Pregnancy and Anthropometric Measures at Birth in a Multicenter Cohort in Spain

2011

Background: A growing body of research suggests that prenatal exposure to air pollution may be harmful to fetal development. We assessed the association between exposure to air pollution during pregnancy and anthropometric measures at birth in four areas within the Spanish Children’s Health and Environment (INMA) mother and child cohort study. Methods: Exposure to ambient nitrogen dioxide (NO2) and benzene was estimated for the residence of each woman (n = 2,337) for each trimester and for the entire pregnancy. Outcomes included birth weight, length, and head circumference. The association between residential outdoor air pollution exposure and birth outcomes was assessed with linear regress…
