Religious vs Secular volunteering motivations: A study on European elders
The reality of volunteering is highly complex. This concept is difficult to define and typify because of the great variety of interpretations, motivations, socio-demographic variables and cultural aspects that shape the volunteer profile. This work aims to analyze the differential and inter-related impact of socio-demographic and contextual variables, and cultural values on elder volunteer profile in Europe. We thus conduct an empirical study involving the use of a logistic regression model that shows, in probabilistic terms, traits that characterize senior and retired volunteers. Further, we study which variables motivate senior volunteers to a determined type of volunteering. Results from the European Value Study help to explain variable influence on volunteering and confirm that cultural values impact among elder people, both, election to volunteering activities and decisions regarding which kind of activity volunteers are drawn to. By analyzing two types of volunteering (religious and secular) that are supposed to be motivated by different forces, we conclude that certain values encourage religious volunteering while others stimulate secular volunteering

Una inscripción de época republicana dedicada a <i>Salaecus</i> en la región minera de Carthago Nova
In this paper we study an unpublished votive inscription from Mina Mercurio (in Portman, Cartagena), exhibited at the Aguilas Archaeological Museum. It is dedicated by freedmen from the <i>gens Roscia</i>, a well-known family of negotiators who used to sign the argentiferous galena ingot hallmark found in Cabezo Rajao in La Unión around 1846. It is one of the oldest inscriptions found in the area of <i>Carthago Noua</i>, and thus, in the whole Hispania. It is dated at the end of the 2nd century or very beginning of the 1st century b.c., especially with the use of an archaic plural nominative in -es. It is dedicated to <i>Salaecus</i>, a vocative etymologically related to water and the sea. For this reason and because of the place where it was found, it might refer to the Roman god Neptune or to a Hispanic deity related to water.<br><br>Estudiamos una inscripción votiva inédita procedente de Mina Mercurio (Portmán, Cartagena), depositada en el Museo Arqueológico de Águilas. La dedican unos libertos de la <i>gens Roscia</i>, conocida familia de <i>negotiatores</i> que firmaban los sellos de lingotes de galena argentífera que aparecieron en el Cabezo Rajao de La Unión, en torno a 1846. Se trata de una de las inscripciones más antiguas de la zona de <i>Carthago Noua</i>. Se fecha a finales del siglo II o principios del siglo I a. C., fundamentalmente a partir de la utilización de un nominativo plural arcaico en <i>-es</i>. Está dedicada a <i>Salaecus</i>, un apelativo que se relaciona etimológicamente con las aguas y con el mar. Por ello y por el lugar donde apareció, formulamos la hipótesis de que haría alusión al dios romano Neptuno o a una deidad hispánica relacionada con el agua
K0S and Λ production in Pb-Pb collisions at sNN−−−−√=2.76 TeV
The ALICE measurement of K0S and Λ production at midrapidity in Pb-Pb collisions at sNN−−−√=2.76 TeV is presented. The transverse momentum (pT) spectra are shown for several collision centrality intervals and in the pT range from 0.4 GeV/c (0.6 GeV/c for Λ) to 12 GeV/c. The pT dependence of the Λ/K0S ratios exhibits maxima in the vicinity of 3 GeV/c, and the positions of the maxima shift towards higher pT with increasing collision centrality. The magnitude of these maxima increases by almost a factor of three between most peripheral and most central Pb-Pb collisions. This baryon excess at intermediate pT is not observed in pp interactions at s√=0.9 TeV and at s√=7 TeV. Qualitatively, the baryon enhancement in heavy-ion collisions is expected from radial flow. However, the measured pT spectra above 2 GeV/c progressively decouple from hydrodynamical-model calculations. For higher values of pT, models that incorporate the influence of the medium on the fragmentation and hadronization processes describe qualitatively the pT dependence of the Λ/K0S ratio
phi-Meson production at forward rapidity in p-Pb collisions at root s(NN)=5.02 TeV and in pp collisions at root s=2.76 TeV
The first study of phi-meson production in p-Pb collisions at forward and backward rapidity, at a nucleonnucleon centre-of-mass energy root s(NN)= 5.02 TeV, has been performed with the ALICE apparatus at the LHC. The phi-mesons have been identified in the dimuon decay channel in the transverse momentum (p(T)) range 1 <p(T) <7GeV/c, both in the p-going (2.03 <y <3.53) and the Pb-going (-4.46 <y <-2.96) directions - where ystands for the rapidity in the nucleon-nucleon centre-of-mass - the integrated luminosity amounting to 5.01 +/- 0.19nb(-1) and 5.81 +/- 0.20nb(-1), respectively, for the two data samples. Differential cross sections as a function of transverse momentum and rapidity are presented. The forward-backward ratio for f-meson production is measured for 2.96Peer reviewe

Measurement of transverse energy at midrapidity in Pb-Pb collisions at root s(NN)=2.76 TeV
We report the transverse energy (ET) measured with ALICE at midrapidity in Pb-Pb collisions at root s(NN) = 2.76 TeV as a function of centrality. The transverse energy was measured using identified single-particle tracks. The measurement was cross checked using the electromagnetic calorimeters and the transverse momentum distributions of identified particles previously reported by ALICE. The results are compared to theoretical models as well as to results from other experiments. The mean ET per unit pseudorapidity (eta), , in 0%-5% central collisions is 1737 +/- 6(stat.) +/- 97(sys.) GeV. We find a similar centrality dependence of the shape of as a function of the number of participating nucleons to that seen at lower energies. The growth in at the LHC energies exceeds extrapolations of low-energy data. We observe a nearly linear scaling of with the number of quark participants. With the canonical assumption of a 1 fm/c formation time, we estimate that the energy density in 0%-5% central Pb-Pb collisions at root s(NN) = 2.76 TeV is 12.3 +/- 1.0 GeV/fm(3) and that the energy density at the most central 80 fm(2) of the collision is at least 21.5 +/- 1.7 GeV/fm(3). This is roughly 2.3 times that observed in 0%-5% central Au-Au collisions at root s(NN) = 200 GeV.Peer reviewe
Azimuthally Differential Pion Femtoscopy in Pb-Pb Collisions at root s(NN)=2.76 TeV
We present the first azimuthally differential measurements of the pion source size relative to the second harmonic event plane in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon pair of root(NN)-N-s = 2.76 TeV. The measurements have been performed in the centrality range 0%-50% and for pion pair transverse momenta 0.2 <k(T) <0.7 GeV/c. We find that the R-side and R-out radii, which characterize the pion source size in the directions perpendicular and parallel to the pion transverse momentum, oscillate out of phase, similar to what was observed at the Relativistic Heavy Ion Collider. The final-state source eccentricity, estimated via R-side oscillations, is found to be significantly smaller than the initial-state source eccentricity, but remains positive-indicating that even after a stronger expansion in the in-plane direction, the pion source at the freeze-out is still elongated in the out-of-plane direction. The 3 + 1D hydrodynamic calculations are in qualitative agreement with observed centrality and transverse momentum R-side oscillations, but systematically underestimate the oscillation magnitude.Peer reviewe
