Chemical fingerprint of outdoor PM2.5 in Malta

2015

Intro: RESPIRA (EU Funded - Italia-Malta 07-13) indicated that living in Malta is a risk factor for asthma. Aim: To determine the chemical profile of PM2.5 in Malta, and compare with reference values. Methods: Using FAI pumps at 10l/min/48hr, samples were collected on Teflon and Quartz filters from 6 schools and 46 homes in Malta. Total ICP-MS measurement (Residual+extracted), X ray Fluorescence, and thermo-optical methods(TO) were used for analysis by CNR in Rome. Aeroqual IQM60 counters were used for total PM2.5 mass. All data in ng/m3, Mean, (1st to 3rd quartile) of all 48 hour measurements.

What is a tree in the Mediterranean Basin hotspot? A critical analysis

2019

Background: Tree species represent 20% of the vascular plant species worldwide and they play a crucial role in the global functioning of the biosphere. The Mediterranean Basin is one of the 36 world biodiversity hotspots, and it is estimated that forests covered 82% of the landscape before the first human impacts, thousands of years ago. However, the spatial distribution of the Mediterranean biodiversity is still imperfectly known, and a focus on tree species constitutes a key issue for understanding forest functioning and develop conservation strategies. Methods: We provide the first comprehensive checklist of all native tree taxa (species and subspecies) present in the Mediterranean-Europ…

Discrepancy between individual and organizational values : occupational burnout and work engagement among white-collar workers

2013

Abstract This pilot study aimed to investigate the level of discrepancy between individual and organizational values, and assessed its impact on white-collar workers' job burnout and work engagement. The study examined the hypothesis that the better the fit between individual and organizational values, the higher the work engagement and the lower the risk of professional burnout. The modified Schwartz's typology of values, focusing on work related issues, was used as a framework for the study. Also, organizational level analysis was incorporated into the study questionnaire in order to capture the potential mismatch effect between the person and his or her work environment. A total of 480 w…

Corroborar llegendes, invocar imatges, renovar la memòria i presentar models. El valor dels goigs en la religiositat valenciana durant la Contrarefor…

2015

Resum: El present article aplica el metode de Pafnosky a l’analisi dels goigs durant el periode de la Contrareforma a Valencia. Determina, amb independencia de la seua forma poeticomusical i melodia, quina va estar la funcio cultural, centrant-nos en quatre exemples diferents. Es confronten les idees subjacents amb altres expressions culturals coetanies –textos historics, hagiografics i devocionals i obres pictoriques-, i s’estableix la relacio reciproca entre els valors culturals del goigs i els de la societat que els genera, demostrant que no foren expressio ingenua de la devocio popular, sino versions reduides i assequibles dels les erudites hagiografies i histories d’imatges i, per tant…

The role of news values in the discur-sive construction of the Brexit refer-endum in the UK press

2022

El objetivo principal de este estudio es explorar el discurso periodístico de la campaña del referéndum del Brexit en Reino Unido desde la perspectiva de los estudios del discurso asistidos por corpus (CADS). En concreto, se analiza cómo se construyeron discursivamente diferentes temas y debates relacionados con el Brexit en la cobertura de la prensa británica de calidad durante la campaña del referéndum. Asimismo, se investigan las diferencias ideológicas en la construcción discursiva de dicha cobertura según las afiliaciones políticas (izquierda-derecha) y las posturas ideológicas hacia el Brexit (Bandos de Salida-Permanencia). Para ello, se recopiló un corpus de cuatro diarios británicos…

Generalized Browder’s Theorem and SVEP

2007

A bounded operator \(T \in L(X), X\) a Banach space, is said to verify generalized Browder’s theorem if the set of all spectral points that do not belong to the B-Weyl’s spectrum coincides with the set of all poles of the resolvent of T, while T is said to verify generalized Weyl’s theorem if the set of all spectral points that do not belong to the B-Weyl spectrum coincides with the set of all isolated points of the spectrum which are eigenvalues. In this article we characterize the bounded linear operators T satisfying generalized Browder’s theorem, or generalized Weyl’s theorem, by means of localized SVEP, as well as by means of the quasi-nilpotent part H0(λI − T) as λ belongs to certain …

A bounded version of bosonic creation and annihilation operators and their related quasi-coherent states

2007

Coherent states are usually defined as eigenstates of an unbounded operator, the so-called annihilation operator. We propose here possible constructions of {\em quasi-coherent states}, which turn out to be {\em quasi} eigenstate of a \underline{bounded} operator related to an annihilation-like operator. We use this bounded operator to construct a sort of modified harmonic oscillator and we analyze the dynamics of this oscillator from an algebraic point of view.

Culture and current account balances

2014

This article contributes to the literature of current account balances by introducing cultural variables that until now have been omitted. The World Values Survey indicates that the Roman Catholics do not consider thrift as important as others. We propose that Catholic countries tend to run current account deficits. This result remains robust even if we control for close to all of the determinants that have been included in previous studies. We find evidence that the inclination of Catholic countries to have high levels of uncertainty avoidance goes to a great length in explaining the result. peerReviewed

Decay estimates in the supremum norm for the solutions to a nonlinear evolution equation

2014

We study the asymptotic behaviour, as t → ∞, of the solutions to the nonlinear evolution equationwhere ΔpNu = Δu + (p−2) (D2u(Du/∣Du∣)) · (Du/∣Du∣) is the normalized p-Laplace equation and p ≥ 2. We show that if u(x,t) is a viscosity solution to the above equation in a cylinder Ω × (0, ∞) with time-independent lateral boundary values, then it converges to the unique stationary solution h as t → ∞. Moreover, we provide an estimate for the decay rate of maxx∈Ω∣u(x,t) − h(x)∣.

Ultrarelativistic bound states in the spherical well

2016

We address an eigenvalue problem for the ultrarelativistic (Cauchy) operator $(-\Delta )^{1/2}$, whose action is restricted to functions that vanish beyond the interior of a unit sphere in three spatial dimensions. We provide high accuracy spectral datafor lowest eigenvalues and eigenfunctions of this infinite spherical well problem. Our focus is on radial and orbital shapes of eigenfunctions. The spectrum consists of an ordered set of strictly positive eigenvalues which naturally splits into non-overlapping, orbitally labelled $E_{(k,l)}$ series. For each orbital label $l=0,1,2,...$ the label $k =1,2,...$ enumerates consecutive $l$-th series eigenvalues. Each of them is $2l+1$-degenerate. …
