    Whose job instability affects the likelihood of becoming a parent in Italy? A tale of two partners

    Get PDF
    We examine the likelihood of becoming a parent in Italy taking into account the employment (in)stability of both partners in a couple. We use data from four waves of the Italian section of the EU-SILC (Statistics on Income and Living Condition), 2004-2007, accounting for its longitudinal nature. Overall, our results suggest that Italian couples are neither fully traditional nor entirely modern: the "first pillar" (i.e., a male partner with a stable and well-paid job) is still crucial in directing fertility decisions, because, in our interpretation, it gives the household a feeling of (relative) economic security. But this "old" family typology is becoming rare. Increasingly, both partners are employed, and in this case the characteristics of their employment prove important. A permanent occupation for both partners is associated with higher fertility, while alternative job typologies for either of the two depress fertility.employment instability, first birth, income, Italy

    SRA: a Salmon-like Approach to MANET Routing,

    Get PDF
    Wireless mobile ad-hoc networks are characterized by the lack of physical connections. Due to the mobility of nodes, interferences, multipath propagations and path losses, they do not exhibit a fixed topology; hence, dynamic routing protocols are required. In recent years, new approaches inspired by nature have been tried: among them, particular interest has been raised by ants and bees colonies. The characteristics inherited by the collective behaviors of social insects empower algorithms with features such autonomy, self-organization, adaptivity, robustness, and scalability. Here, we propose a salmon-based approach, that, although different since salmons do not show evidence of social behaviors, suggests interesting cues to solve the routing problem when observing salmons in their way from the birth river to the sea, and back at the spawning time

    Upward Tau Air Showers from Earth

    We estimate the rate of observable Horizontal and Upward Tau Air-Showers (HORTAUs, UPTAUS) considering both the Earth opacity and the finite size of the terrestrial atmosphere. We calculate the effective target volumes and masses for Tau air-showers emerging from the Earth. The resulting model-independent masses for satellite experiments such as EUSO may encompass at E_nu_tau = 10^19 eV a very large volume, V= 1020 km^3. Adopting simple power law neutrino fluxes, E^-2 and E^-1, calibrated to GZK-like and Z-Burst-like models, we estimate that at E= 10^19 eV nearly half a dozen horizontal shower events should be detected by EUSO in three years of data collection by the "guaranteed" GZK neutrino flux. We also find that the equivalent mass for an Earth outer layer made of rock is dominant compared to the water, contrary to simplified all-rock/all-water Earth models and previous Montecarlo simulations. Therefore we expect an enhancement of neutrino detection along continental shelves nearby the highest mountain chains, also given the better geometrical acceptance for Earth skimming neutrinos. The Auger experiment might reveal such a signature at E_nu= 10^{18} eV (with 26 events in 3 yr) towards the Andes, if the angular resolution at the horizon (both in azimuth and zenith) would reach an accuracy of nearly one degree needed to disentangle tau air showers from common UHECR. The number of events increases at lower energies; therefore we suggest an extension of the EUSO and Auger sensitivity down to (or even below) E_nu = 10^19 eV and E_nu = 10^18 eV respectively.Comment: New version resubmitted to ApJ on the 6th April 2004; 55 Pages,20 figures, major changes following referee reques

    Analysing occupational safety culture through mass media monitoring

    Get PDF
    In the last years, a group of researchers within the National Institute for Insurance against Accidents at Work (INAIL) has launched a pilot project about mass media monitoring in order to find out how the press deal with the culture of safety and health at work. To monitor mass media, the Institute has created a relational database of news concerning occupational injuries and diseases, that was filled with information obtained from the newspaper articles about work-related accidents and incidents, including the text itself of the articles. In keeping with that, the ultimate objective is to identify the major lines for awareness-raising actions on safety and health at work. In a first phase of this project, 1,858 news articles regarding 580 different accidents were collected; for each injury, not only the news texts but also several variables were identified. Our hypothesis is that, for different kind of accidents, a different language is used by journalists to narrate the events. To verify it, a text clustering procedure is implemented on the articles, together with a Lexical Correspondence Analysis; our purpose is to find language distinctions connected to groups of similar injuries. The identification of various ways in reporting the events, in fact, could provide new elements to describe safety knowledge, also establishing collaborations with journalists in order to enhance the communication and raise people attention toward workers' safety

    Introduction

    Get PDF
    No better analogy can be found to indirectly “illustrate” and thus describe the vicissitudes of the thought of Rudolf Hermann Lotze than what Don Abbondio exclaims about Carnades in Alessandro Manzoni’s 1827 masterpiece I promessi sposi. Carneades was in fact one of the most important and famous thinkers of the Hellenic period; as one of the great heads of the Platonic Academy after Arcesilaus, he was sent to Rome in 155 BC to lecture on justice (together with Diogenes of Babylon and Critolaus). Apparently, more than 400 books were written about him. And yet, the question that Don Abbondio asks himself (“Carnades! Who was he?”) reveals how little his name is known outside the quite restricted circles of professional scholarship[1].[1] M. Bonazzi, Il platonismo (Milan: Einaudi, 2015)

    Husserl on the Existence of Only One Real World Synthesis and Identity (II)

    Get PDF
    This paper aims at discussing a quite specific aspect of Husserl’s phenomenology, i.e., the notion of synthesis of identification, and the role it plays in the arguments set forward in the Fifth Cartesian Meditation during the discussion of the constitution of the other, hence of the monadological inter-subjectivity. The case will be made for considering the very heart of the Meditation to be what we will refer to as Husserl’s “transcendental argument”, consisting in the claim that there can be only one inter-subjectivity, hence, the “world” being the correlate of the transcendental monadological inter-subjectivity, only one real and actual world. This will also give us the opportunity to critically approach a series of views lately held by some leading figures of the “continental” and “analytic” tradition, which, as the first part of the essay will show, pursue views directly opposed to Husserl’s

    The double meaninf of différance : remarks on its first appearance

    Get PDF
    It is in 1965 that, as well known, Derrida publishes in Tel Quel one of his most important writings on Antonin Artaud : La parole soufflĂ©e. In what follow, however, the deep meaning of such an essay is not immediately related to the specifically Artaudian questions it arises, but to the fact that Derrida’s most famous neologism – diffĂ©rance – makes between its pages (for three times) the first appearance. It is in any case important to keep in mind the distinction between its two different ed..

    On husserlian eidetic variation and its duplicity: “contingency-variation” or “similarity-variation”?

    Get PDF
    Whoever deals with the issue of eidos in Husserl’s phenomenology cannot repress an uncomfortable sensation due to the fact that, if on the one hand the Husserlian Denkweg unfolds itself unitarily, at least at the level of a certain number of basic methodological acquisitions (and eidetic analysis is to number among these), on the other hand the emergence of eidetic variation marks a decisive passage within the Husserlian conceptuality and methodology. Passage that usually, however, seems to r..
