Forms of collective leadership, such as Distributed Leadership, have become increasingly important. The need for measurement of the variables involved in the delegation processes, represents a new challenge for organizations that want to ensure high-level working. The present research aimed to validate the Italian version of the Distributed Leadership Agency (DLA) and verify its applicability in different contexts. The study involved all the employees of an Italian public Hospital, which were selected to complete a survey on organizational perceptions. The sample (...) comprised 704 employees (doctors, nurses, clerks, staff workers, healthcare assistants, consultants, management). Multiple Confirmatory Factor Analyses (Maximum Likelihood) have been computed to explore the factorial structure of the DLA, along with associations with other work outcomes. Results clarified that the Italian DLA respects the tri-factorial structure of the construct, suggested by Yukl (2002), with good fit indexes and reliability; moreover, in line with the literature, DLA was strongly related to satisfaction, commitment, and trust. Results contribute to underline the robustness of the construct of distributed leadership agency in different cultural sectors, and provide a useful tool to be adopted in the Italian context.

I teoremi di Gödel suscitano un interesse sempre crescente nella riflessione filosofica contemporanea. Rimane però in discussione fra gli studiosi come si sia arrivati alla loro scoperta e quale sia il loro significato per il dibattito sui fondamenti delle scienze. Nel volume si ripercorrono le vicende che portarono alla formulazione dei teoremi di incompletezza, a partire dall’incontro tra von Neumann e Gödel al Congresso di Königsberg nel 1930, e si indaga, riferendosi in particolare al lavoro di von Neumann, sull’impatto che (...) questi teoremi hanno avuto per il progetto hilbertiano di fondazione della matematica e delle scienze più in generale. Ne risulta un’immagine delle indagini di Hilbert meno rigida di quella finora corrente, in linea con le più recenti acquisizioni della storiografia, e soprattutto più rispettosa della stessa prassi assiomatica, che oscillava per Hilbert tra ambizioni fondazionaliste e istanze pragmatiche. È stato von Neumann a rendere esplicita, dopo la scoperta dei teoremi di Gödel, quella che si può definire come la “svolta pragmatica” nell’assiomatica. Il libro propone inoltre un chiarimento riguardo alla scoperta di von Neumann del secondo teorema di incompletezza. (shrink)

Giambattista Vico (1668-1744) was one of the most original and idiosyncratic philosophers before Kant and Hegel. Although Giorgio Vasari had already diagnosed a cycle of rise, blossoming and decline in the history of art, Vico was the first to base this on a philosophical system. Isolated in Naples from direct contact with the philosophical life of his times, he worked at his grand design of the cycles of rise, blossoming, decline and eternal return which he saw in all areas (...) of culture. His points of reference were ancient mythology and Greek and Roman history. To that extent, he is regarded today as the founder of the philosophy of history and the precursor of a tradition which extends to Hegel and Oswald Spengler's "Decline of the West". (shrink)

The relatedness between a country or a firm and a product is a measure of the feasibility of that economic activity. As such, it is a driver for investments at a private and institutional level. Traditionally, relatedness is measured using networks derived by country-level co-occurrences of product pairs, that is counting how many countries export both. In this work, we compare networks and machine learning algorithms trained not only on country-level data, but also on firms, which is something not much (...) studied due to the low availability of firm-level data. We quantitatively compare the different measures of relatedness, by using them to forecast the exports at the country and firm level, assuming that more related products have a higher likelihood to be exported in the future. Our results show that relatedness is scale dependent: the best assessments are obtained by using machine learning on the same typology of data one wants to predict. Moreover, we found that while relatedness measures based on country data are not suitable for firms, firm-level data are very informative also for the development of countries. In this sense, models built on firm data provide a better assessment of relatedness. We also discuss the effect of using parameter optimization and community detection algorithms to identify clusters of related companies and products, finding that a partition into a higher number of blocks decreases the computational time while maintaining a prediction performance well above the network-based benchmarks.

Hilbert’s axiomatic approach to the sciences was characterized by a dynamic methodology tied to scientific and mathematical fields under investigation. In particular, it is an analytic art for choosing axioms but, at the same time, it has to include dynamically synthetic procedures and meta-theoretical reflections. Axioms have to be useful, or capture something, or help as part of explanations. The Andréka-Németi group use several formal axiomatic theories together to re-capture, predict, recover or explain the phenomena of special relativity, general relativity (...) and classical kinematics. Their scientific methodology is close to Hilbert’s conceptions of how science should be done ideally. In this paper, we compare Formica’s reading of Hilbert’s axiomatic method to the method used by the Andréka-Németi group. (shrink)

In this paper we address the problem of combining a logic with nonmonotonic modal logic. In particular we study the intuitionistic case. We start from a formal analysis of the notion of intuitionistic consistency via the sequent calculus. The epistemic operator M is interpreted as the consistency operator of intuitionistic logic by introducing intuitionistic stable sets. On the basis of a bimodal structure we also provide a semantics for intuitionistic stable sets.

Malebranche and the Search after Lost Identity. Legacy and Uncertainty of His Philosophy between the Eighteenth and Twentieth Centuries. Starting from the Œuvres complètes edited by Robinet, the article summarizes the vicissitudes through which the French historical scholarship with its leading figure Victor Cousin have restored the imagine and the correspondence of Malebranche, beginning with the dissemination of the original documents, conserved throughout the eighteenth century by P. Lelong, P. André, and finally P. Adry. In spite of his great historical (...) contribution, the French scholarship generally stressed an inadequate assessment of this philosophy, sharply suspected of spinozism, a judgment inherited by the handbooks of the history of philosophy edited between the XIX and the XX Century, as proved by the case of Grundriss der Geschichte der Philosophie by Überweg. The article concludes with three minimalist but creative readings of Malebranche by Proust, Heisenberg, Dalì. (shrink)

In the same year that, just a few days before his death, Locke was penning instructions to for the publication of some of his unprinted works, in particular of the Paraphrases on the Epistles of Saint Paul, a book entitled The Two Covenants of God with Mankind was published in London. The author, Thomas Taylor, had been for some time a staunch supporter of the thought and work of Malebranche, to whom the subtitle made explicit reference. It was during his (...) studies at Oxford that Taylor had begun to approach Malebranche’s thought, very probably through John Norris his chief English mentor. Indeed, Taylor referred to Norris in the notice To the Reader in his work, both explicitly as—“one who best understands [Malebranche]”—and by reutilising the encomiastic optical and astronomical metaphors with which Norris introduced the French philosopher at the beginning of The Theory of the Ideal or Intelligible World. Also traceable to the authority of Norris was Taylor’s eulogy of the Recherche de la vérité—“a Book that is alone a Library”—that he had translated 10 years earlier, which, along with the almost contemporary translation by Richard Sault, rendered Malebranche’s most influential work accessible to English readers. Taylor’s translation can be set within the context of Locke’s earliest stances regarding the theory of ideas of Malebranche and Norris, the principal documentation of which was to be found in Of Seeing all Things in God, another of the unpublished works mentioned by Locke in the letter to Peter King. King did indeed publish it in the Posthumous Works, albeit without the polemical initial paragraphs directed against Norris, whereas the editorial history of the Paraphrases was to be different.

In spite of the many efforts made to clarify von Neumann’s methodology of science, one crucial point seems to have been disregarded in recent literature: his closeness to Hilbert’s spirit. In this paper I shall claim that the scientific methodology adopted by von Neumann in his later foundational reflections originates in the attempt to revaluate Hilbert’s axiomatics in the light of Gödel’s incompleteness theorems. Indeed, axiomatics continues to be pursued by the Hungarian mathematician in the spirit of Hilbert’s school. I (...) shall argue this point by examining four basic ideas embraced by von Neumann in his foundational considerations: a) the conservative attitude to assume in mathematics; b) the role that mathematics and the axiomatic approach have to play in all that is science; c) the notion of success as an alternative methodological criterion to follow in scientific research; d) the empirical and, at the same time, abstract nature of mathematical thought. Once these four basic ideas have been accepted, Hilbert’s spirit in von Neumann’s methodology of science will become clear. (shrink)

The paper deals with the controversial issue of realism in Wittgenstein’s Tractatus. Most of the problems are grounded in the logical-linguistic foundation of important ontological notions given within the text (such as object, state of affairs, fact, etc.). This has led some scholars to think that there is no conception of the world in the Tractatus that is independent of language and that in his work Wittgenstein is simply engaged in a logical investigation of what it is essential for any (...) language to represent reality. Therefore, no conclusions about a transcendent world can be drawn from it. Here we argue that it is true that the author of the Tractatus is engaged in a logical investigation, conducted a priori and internal to language, on the conditions that are (or have to be) satisfied by any significant language. However, what such an investigation reveals, given one of these languages, is the necessity to presuppose a world made in a certain way and transcendent to the language that pretends to describe it. Two issues are considered to clarify the sense of the realism of the Tractatus — that of the existence of simple objects, and that of the truth of propositions — and a new interpretative schema for the text is advanced.
