Libertà del volere e concetto di persona nella filosofia dello spirito di Hegel

Hegel’s definition of ‘free will’ and ‘person’ gets over a phenomenological or psychological definition of these concepts. My essay explains how Hegel justifies the placing of his theory of free will in a philosophy of Mind analyzing the concept of ‘recognition’ in the Phenomenology as a section of the Encyclopedia of Philosophical Sciences as well as the main steps of The practical Spirit, the second part of the section Psychology. With regard to this last science my essay clarifies the essential differences between freedom of the will and freedom of choice. These differences only explain how the free will could develop as objective Spirit in the third science involved by Hegel towards a proper definition of freedom, i.e. the philosophy of Right. In the philosophy of Right as a part of Hegel’s System of philosophical sciences the free will finds its own adequate reality and the concept of a person can be explained without the mistakes caused by a phenomenological or psychological approach to it. Against some interpretations which identify Hegel’s definition of free will with communitarian practices, the final part of my essay focuses on the importance of the concept of a person to explain the general structure of the philosophy of Right

Critical sets of nonlinear Sturm-Liouville operators of Ambrosetti-Prodi type

The critical set C of the operator F:H^2_D([0,pi]) -> L^2([0,pi]) defined by F(u)=-u''+f(u) is studied. Here X:=H^2_D([0,pi]) stands for the set of functions that satisfy the Dirichlet boundary conditions and whose derivatives are in L^2([0,pi]). For generic nonlinearities f, C=\cup C_k decomposes into manifolds of codimension 1 in X. If f''0, the set C_j is shown to be non-empty if, and only if, -j^2 (the j-th eigenvalue of u -> u'') is in the range of f'. The critical components C_k are (topological) hyperplanes.Comment: 6 pages, no figure

A simulation code to assist designing space missions of the Airwatch type

The design of an Airwatch type space mission can greatly benefit from a flexible simulation code for establishing the values of the main parameters of the experiment. We present here a code written for this purpose. The cosmic ray primary spectrum at very high energies, the atmosphere modelling, the fluorescence yield, the photon propagation and the detector response are taken into account in order to optimize the fundamental design parameters of the experiment, namely orbit height, field of view, mirror radius, number of pixels of the focal plane, threshold of photo-detection. The optimization criterion will be to maximize counting rates versus mission cost, which imposes limits both on weight and power consumption. Preliminary results on signals with changing energy and zenith angle of incident particles are shown

La historiografía sobre el desarrollo económico italiano en los últimos treinta años

Editada en la Universidad Carlos IIIEste ensayo analiza la historiografía del crecimiento económico italiano moderno, distinguiendo entre los enfoques que consideran a Italia como un caso más en el proceso general de industrialización europea y aquellos que identifican unas características específicas y únicas del caso italiano. Se pasa revista también en este trabajo a los intentos de hallar una cronología del desarrollo en Italia y de establecer sus causas y condiciones.This essays analyzes the historiography of Italy's modern economic growth. A distinction is made between those interpretations that emphasize the uniqueness of the Italian experience and those that include Italy in the general process that started in Britain and spread to the rest of Europe through the nineteenth and twentieth centuries. In addition, the article surveys the most recent attempts to establish the timing, the causes, and the obstacles to Italy's economic growth during the last century.Publicad

The Cosmic-Ray Proton and Helium Spectra measured with the CAPRICE98 balloon experiment

A new measurement of the primary cosmic-ray proton and helium fluxes from 3 to 350 GeV was carried out by the balloon-borne CAPRICE experiment in 1998. This experimental setup combines different detector techniques and has excellent particle discrimination capabilities allowing clear particle identification. Our experiment has the capability to determine accurately detector selection efficiencies and systematic errors associated with them. Furthermore, it can check for the first time the energy determined by the magnet spectrometer by using the Cherenkov angle measured by the RICH detector well above 20 GeV/n. The analysis of the primary proton and helium components is described here and the results are compared with other recent measurements using other magnet spectrometers. The observed energy spectra at the top of the atmosphere can be represented by (1.27+-0.09)x10^4 E^(-2.75+-0.02) particles (m^2 GeV sr s)^-1, where E is the kinetic energy, for protons between 20 and 350 GeV and (4.8+-0.8)x10^2 E^(-2.67+-0.06) particles (m^2 GeV nucleon^-1 sr s)^-1, where E is the kinetic energy per nucleon, for helium nuclei between 15 and 150 GeV nucleon^-1.Comment: To be published on Astroparticle Physics (44 pages, 13 figures, 5 tables
