John Rawls's Justice as Fairness: anti-foundationalism, deliberative democracy, and cosmopolitanism
This paper aims at illustrating through a close reading of the works of John Rawls the anti-foundationalist cosmopolitan deliberative democratic approach to liberalism that I have sketched in the IIIS Discussion Paper N.47. I shall argue that despite what some of his critics believe Rawls' liberal theory of justice 1) is not concerned with foundational preoccupations (e.g. Michael Sandel); 2) does not ignore concrete processes of collective deliberation over matters of public interests (e.g. Amy Guttman, Dennis Thomson, Brian Barry); 3) nor does it endorse rigid limits to the scope of democratic deliberation (e.g. Jeremy Waldron, John Gray, Richard Bellamy ). Yet I shall claim, following Andrew Kuper, that 4) there is a real risk of infringing individuals' primary moral significance in trying to stretch too much the limits of liberal toleration in order to accommodate political liberalism with multiculturalism in the international sphere.
Geografía de la población : acerca de ciertas falacias en el empleo de las tasas brutas
El objetivo de este trabajo es presentar dos métodos empleados en
Demografía (el método de la tasa-tipo y el método de la población-tipo) que
permiten transformar las tasas brutas en tasas comparativas. Estas técnicas
son de extrema utilidad para evitar las comparaciones falaciosas cuando se
desea cotejar dos (o más) poblaciones frente a un fenónemo demográfico.
Para ejemplificar la aplicación de los métodos presentados, se utilizan las
tasas brutas de mortalidad general de departamentos de la provincia de
Mendoza.Géographie de la population: á propos des conclusions fallacieuses
dans I ' emploi des taux bruts. Le but de cet article est de présenter deux
méthodes utilisées en Démographie (la méthode de la population-type et la
méthode de la mortalité-type) qui permettent de transformer les taux bruts en
taux comparatifs. Ces techniques sont trés útiles car elles evitent les comparations
fallacieuses lorsqu'on veut comparer deux populations face á un
phénoméne démographique. Les techniques préscntées sont appliquées aux
taux bruts de mortalité général des unités administratives de la province de
Mendoza.Geography of population: about some fallacious conclusions of
crude rate use.
The purpose of this paper is to present two methods in Demography (Direct
Standardization and Indirect Standardization) which allow for the conversión
of crude rate into comparative index. Those techniques are very useful to
avoid fallacious comparations if one wants to compare the behaviour of two
or more populations when confronted with a demógraphie
phenomenon.
To illustrate these methods mortality crude rates are used from departments
of Mendoza.Fil: Trifiró, María Cristina.

Mapping the demise of collective motion in nuclei at high excitation energy
High energy gamma-rays from the 116Sn + 24Mg reaction at 23A MeV were measured using the MEDEA detector at LNS – INFN Catania. Combining this new data with previous measurements yields a detailed view of the quenching of the Giant Dipole Resonance as a function of excitation energy in nuclei of mass A in the range 120÷132. The transition towards the disappearance of the dipole strength, which occurs around 230 MeV excitation energy, appears to be remarkably sharp. Current phenomenological models give qualitative explanations for the quenching but cannot reproduce its detailed features.

Competition between dynamical and sequential reaction channels in ^{197}Au+^{197}Au collisions at a bombarding energy of 23A MeV
Competition between the two reaction channels: sequential breakup and neck fragmentation has been studied in peripheral and semi-peripheral collisions of the 197 Au+ 197 Au system at bombarding energy of 23A MeV. It was found that the emission of heavy (A < 50) neck-originating fragments occurs in about 22% of ternary breakup events, making this reaction channel highly competitive with the sequential breakup of the projectile- or target-like fragment (78% of events)
Persistence of odd-even staggering in charged fragment yields from the 112Sn+58Ni collision at 35 MeV/nucleon
Odd-even staggering effects on charge distributions are investigated for
fragments produced in semiperipheral and central collisions of 112Sn+58Ni at 35
MeV/nucleon. For fragments with Z<16 one observes a clear overproduction of
even charges, which decreases for heavier fragments. In peripheral collisions
staggering effects persist up to Z about 40. For light fragments, staggering
appears to be substantially independent of the centrality of the collisions,
suggesting that it is mainly related to the last few steps in the decay of hot
nuclei.Comment: 5 pages, 6 figure
Elliptic and triangular flow of (anti)deuterons in Pb-Pb collisions at sNN =5.02 TeV
The measurements of the (anti)deuteron elliptic flow (v2) and the first measurements of triangular flow (v3)
in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon collision √sNN = 5.02 TeV are presented.
A mass ordering at low transverse momentum (pT) is observed when comparing these measurements with those
of other identified hadrons, as expected from relativistic hydrodynamics. The measured (anti)deuteron v2 lies
between the predictions from the simple coalescence and blast-wave models, which provide a good description
of the data only for more peripheral and for more central collisions, respectively. The mass number scaling, which
is violated for v2, is approximately valid for the (anti)deuterons v3. The measured v2 and v3 are also compared
with the predictions from a coalescence approach with phase-space distributions of nucleons generated by IEBEVISHNU with AMPT initial conditions coupled with URQMD, and from a dynamical model based on relativistic
hydrodynamics coupled to the hadronic afterburner SMASH. The model predictions are consistent with the data
within the uncertainties in midcentral collisions, while a deviation is observed in the most central collisions
