Market inefficiency is a latent concept, and it is difficult to be measured by means of a single indicator. In this paper, following both the adaptive market hypothesis and the fractal market hypothesis, we develop a new time-varying measure of stock market inefficiency. The proposed measure, called composite efficiency index, is estimated as the synthesis of the most common efficiency measures such as the returns’ autocorrelation, liquidity, volatility, and a new measure based on the Hurst exponent, called the Hurst efficiency (...) index. To empirically validate the indicator, we compare different European stock markets in terms of efficiency over time. (shrink)

This work evaluated the structure of dreams in people affected by schizophrenia. The verbal reports of 123 schizophrenic patients were compared with 123 dream reports from a control group. In accordance with the Jungian conceptualization of, dreams as texts, dream reports were assessed using textual analysis processing techniques.Significant differences were found in textual parameters, showing that the dreams reports of schizophrenic patients differ from those of the control group. It is thus possible that schizophrenia probably underlies changes in the oneiric (...) production and dream reports. This work confirms the value of textual analysis in the study of oneiric material.

BackgroundData processing of health research databases often requires a Data Protection Impact Assessment to evaluate the severity of the risk and the appropriateness of measures taken to comply with the European Union General Data Protection Regulation. We aimed to define and apply a comprehensive method for the evaluation of privacy, data governance and ethics among research networks involved in the EU Project Bridge Health.MethodsComputerised survey among associated partners of main EU Consortia, using a targeted instrument designed by the principal investigator (...) and progressively refined in collaboration with an international advisory panel. Descriptive measures using the percentage of adoption of privacy, data governance and ethical principles as main endpoints were used for the analysis and interpretation of the results.ResultsA total of 15 centres provided relevant information on the processing of sensitive data from 10 European countries. Major areas of concern were noted for: data linkage, access and accuracy of personal data and anonymisation procedures. A high variability was noted in the application of privacy principles.ConclusionsA comprehensive methodology of Privacy and Ethics Impact and Performance Assessment was successfully applied at international level. The method can help implementing the GDPR and expanding the scope of Data Protection Impact Assessment, so that the public benefit of the secondary use of health data could be well balanced with the respect of personal privacy.

La "Grande Morale," progettata da J.-P. Sartre tra il 1947 e il 1949 come naturale completamento della filosofia esistenzialista esposta ne L'essere e il nulla e L'esistenzialismo e un umanismo, non e mai stata pubblicata: abbandonata e ripresa piu volte nei successivi vent'anni, ha finito per costituire un serbatoio di annotazioni e di riflessioni sempre dirottate altrove, una specie di fantasma letterario, onnipresente, ma pronto a dileguarsi ogni volta che sembrava avere raggiunto una forma consistente. Sappiamo oggi, grazie alla pubblicazione (...) dei molti inediti sartriani, che la riflessione sulla morale ha accompagnato tutti gli snodi fondamentali del pensiero di Sartre, dai cosiddetti scritti giovanili alle opere della maturita, dalla svolta "dialettica" sino all'ultima discussa intervista, rilasciata poco prima della scomparsa. Gli studi qui riuniti hanno nei Quaderni per una morale (1947-48) il loro centro di gravita e di maggiore interesse. Di questo tentativo abortito di scrivere una "Morale" essi provano a disegnare la parabola, dalle origini remote nei Taccuini della strana guerra (1939) sino al Santo Genet commediante e martire (1952), che ne sancisce l'abbandono. Senza disdegnare qualche incursione nell'estetica sartriana, poiche della "morale introvabile" non c'e in realta testo che non rechi qualche traccia.". (shrink)

Despite that it is commonly accepted that migraine is a disorder of the nervous system with a prominent genetic basis, it is comorbid with a plethora of medical conditions. Several studies have found bidirectional comorbidity between migraine and different disorders including neurological, psychiatric, cardio- and cerebrovascular, gastrointestinal, metaboloendocrine, and immunological conditions. Each of these has its own genetic load and shares some common characteristics with migraine. The bidirectional mechanisms that are likely to underlie this extensive comorbidity between migraine and other (...) diseases are manifold. Comorbid pathologies can induce and promote thalamocortical network dysexcitability, multi-organ transient or persistent pro-inflammatory state, and disproportionate energetic needs in a variable combination, which in turn may be causative mechanisms of the activation of an ample defensive system with includes the trigeminovascular system in conjunction with the neuroendocrine hypothalamic system. This strategy is designed to maintain brain homeostasis by regulating homeostatic needs, such as normal subcortico-cortical excitability, energy balance, osmoregulation, and emotional response. In this light, the treatment of migraine should always involves a multidisciplinary approach, aimed at identifying and, if necessary, eliminating possible risk and comorbidity factors. (shrink)

This handbook offers a deep analysis of the main forms of legal reasoning and argumentation from both a logical-philosophical and legal perspective. These forms are covered in an exhaustive and critical fashion, and the handbook accordingly divides in three parts: the first one introduces and discusses the basic concepts of practical reasoning. The second one discusses the main general forms of reasoning and argumentation relevant for legal discourse. The third one looks at their application in law as well as at (...) the different areas of legal reasoning. The handbook’s division in three parts reflects its conceptual architecture, since legal reasoning and argumentation are considered in relation to the more general types of reasoning. (shrink)

In this essay, we reconsider two themes particularly discussed by the interpreters of Ockham: that of divine omnipotence and the hypothesis of the intuitive cognition of non-existent things. The purpose is to show that the hypothetical case considered by Ockham was subjected to opposite interpretations. For theological reasons, Ockham attributes not only to God but also to human beings the possibility of having acts of intuitive cognition of things that do not exist; nonetheless, he holds that it is contradictory for (...) God to give us the evident cognition of things that appear to be present when they are actually absent. Walter Chatton opposes this conclusion, arguing that no contradiction ensues from that hypothesis. Instead, he believes that it is impossible for God to give us the intuition of things that absolutely do not exist or are in no way present to us. Ockham’s arguments include some difficulties that Chatton acutely sees and discusses. In particular, Chatton calls into question Ockham’s missed distinction between the existence and the presence of the intuited thing. (shrink)

What is the origin and meaning of our aesthetic sense? Is it genetically encoded or is it culturally inherited? The aim of the essay is to answer to such issues by defining the emergent and meta-functional character of the aesthetic attitude. First, I propose to include the faculty of desire in the free play of the cognitive faculties at the center of Kant’s Critique of Judgment. The following step is given by a brief analysis of Darwin’s controversial remarks on the (...) pre-human birth of aesthetics and its relationship with sexual selection (§§ 1-2). The point of discontinuity between a mere animal aesthetic sense and a proto-human one is then found to become indeterminate of desire in the correlative diversification of aesthetic attractors (§§ 3-4). Successively, I deal with the supervenience character of the aesthetic and its anticipatory value. After a short genealogy of the notion of supervenience, I then develop its affinity with that of epigenesis (§§ 5-6). Afterwhich follows a review of two contemporary evolutionary perspectives on aesthetics: T. Deacon’s essay on the “aesthetic faculty” and J. Tooby and L. Cosmides thesis on the evolutionary meaning of the aesthetic-fictional activities (§§ 7-8). Conclusively, the epigenesis of an aesthetic mind is considered as the unity between the breath of aísthesis and the breath of linguistic sign (§§ 9-10). (shrink)

Truth is a key notion in Ockham’s philosophical reductionist program, a notion that has been the object of contrasting interpretations in scholarship. My interpretation is that, for Ockham, ‘being true’ expresses an epistemological relation, namely the one through which our mind reflects on a proposition of language, compares it with an extra-mental state of affairs, and thus ascertains their correspondence. Placing truth at a point of intersection of language with mind and reality, Ockham’s interpretation of Aristotle’s characterization of philosophy as (...) the science of truth comes to be innovative. For Ockham, philosophy is a meticulous training of interpretation of language in order to account correctly for the truth-value of propositions. (shrink)

The theology of Pier Damiani († 1072) is still an understudied theme in his scholarship, in particular, for what it concerns his Trinitarian and Christological doctrines. The aim of this study is to reconstruct and discuss especially Damiani’s Christological views as formulated in Letter 81, better known as his De fide catholica. It is argued that Damiani’s approach is mostly exegetical, as he mainly points to and comments on Biblical passages in support of Catholic doctrines. Still, he assumes a peculiar (...) method of investigation, as he devotes the main body of the Letter to the question of the correct understanding (recta intelligentia) of the Catholic interpretation of Christology, and reserves only the final summary to a discussion of Biblical authorities. Eventually, it is argued that despite Damiani’s attempts at clarifying the matter, he acknowledges an inherent difficulty in explaining how it is possible that God became man without truly assuming the person of man, and, if He did so, how this did not give rise to two, however indistinct, persons or hypostases. The concept of ‘co-union’ of human and divine natures, introduced by Damiani, makes the simultaneous unity and distinction of the two natures intuitively clear, but it remains a concept that is not clarified in all its details and implications.

The aim of this study is to illustrate the role played by Augustine’s Commentary on the Genesis in the writings of Thomas Aquinas. This work is of great importance for Aquinas, not only because it is the work where Augustine clarifies his interpretation of creation, but also because creation is, among the theological topics, perhaps the most philosophical, insofar as it gives the opportunity of elaborating on many philosophical issues. In particular, the goal of the study is to rethink the (...) positions of Aquinas and Augustine on one of these issues, that is the relationship between soul and body. I mean to call into question two historiographical theses: first, that Augustine and Aquinas formulate positions that are irreconcilable with each other, and second, that they in no way address that which we today call the Mind-Body Problem.

Il pensatore domenicano Francesco da Prato, attivo nel secondo quarto del XIV sec. tra Perugia, Siena e Firenze, rappresenta una delle prime testimonianze in Italia della ricezione di Ockham e di reazione tomista alla sua logica. Lo studio si articola in due sezioni: nella prima l'A. esamina la dottrina della significazione nelle fonti principali degli scritti di logica di Francesco: Tommaso d'Aquino, Herveus Natalis e Guglielmo di Ockham; nella seconda analizza la posizione di Francesco in scritti trasmessi nei seguenti mss: (...)

L’articolo esamina il rapporto fra individuo e comunità nel pensiero politico di Tommaso d’Aquino. In particolare, il problema filosofico qui discusso può es­sere presentato nel modo seguente: secondo Tommaso, l’essere di un singolo in­­dividuo è determinato dalla sua appartenenza a una data comunità politica o, vice­versa, l’essere di una comunità dipende da quello di ciascuno dei suoi mem­bri? L’articolo argomenta che Tommaso ha alcune ragioni filosofiche per an­teporre la comunità all’individuo, ma anche alcune ragioni teologiche per porre al centro l’individuo. (...) Alla fine, l’interpretazione è che, nonostante al­cu­ne possibili oscillazioni, Tommaso assuma che essere parte di una comunità po­litica, o essere cittadini, sia una proprietà necessaria ma non essenziale per definire l’essere uomo.This paper aims to reconstruct the relationship between individual and com­munity in Thomas Aquinas’s political thought. The philosophical problem I discuss is the following: On Aquinas’s writings, is the metaphysical value of an individual man finally expressed by its belonging to a certain political com­munity or, vice versa, the value of a community ensue from that of its mem­berships? I show that Aquinas has some philosophical arguments to put the community before the individual, but also some theological reasons to prefer the individual. At the end of the day, my interpretation is that, except for some hesitations that can be found in his writings, Aquinas subscribes to the view that the property of being a member of a political community, namely being a citizen, is a necessary but not an essential property for being a man.

Per trovare un'utilizzazione del problema posto in Z6 da Aristotele l'A. considera i testi di autori medievali relativi ai problemi dell'identità tra una realtà accidentale e la propria essenza. Anzitutto è ricostruito il testo aristotelico, poi sono sviluppate considerazioni sui modelli dell'interpretazione del tema nei secoli XIII e XIV. L'A. intende mostrare come le letture che in epoca moderna sono date del problema posto da Aristotele già si trovano in autori medievali e come tali soluzioni siano deducibili da un testo (...) aperto a diverse soluzioni interpretative. Infine, l'A. si interroga sulla rilevanza della problematica nella messa a punto del problema dello statuto ontologico degli accidenti. I testi esaminati sono cinque expositiones alla Metafisica, di Alberto, Tommaso d'Aquino, Antonio d'Andrea, Alessandro d'Alessandria e Paolo Veneto, oltre che questiones di Agostino Trionfo d'Ancona, Galfredo di Aspal, Pietro d'Alvernia e testi anonimi: Anonymus domus Petri, Anonymus Zimmermanni.

Nella relazione presentata al II Convegno dell'Associazione di Studi Tardoantichi, Riccardo Maisano osservava che solo con l'edizione di Grosdidier de Matons, apparsa tra il 1964 e il 1981, «ha inizio il vero e proprio dialogo fra l'opera di Romano e il pubblico occidentale. Per la prima volta gli inni sono sistematicamente tradotti, introdotti e annotati dallo stesso filologo curatore dell'edizione critica, e la medesima unità di intenti guida anche la compilazione dell'apparato delle varianti, rendendo al lettore un servigio inestimabile». Ma (...) poiché la prematura scomparsa dello studioso, al quale Maisano riconosce «appassionata adesione alla materia» e «signorile onestà intellettuale» (I, p. 75), impedì che l'opera venisse portata a termine, la presente risulta essere la prima edizione criticamente rivista, tradotta e commentata in modo completo: oltre ai 59 contaci di sicura attribuzione, essa comprende in appendice anche alcuni carmina dubia (83, 84, 87 Maas-Trypanis), nonché l'Inno acatisto, che sicuramente non può essere assegnato al Melodo (II, p. 580), ma del quale è ristampata la traduzione di Carlo Del Grande (Firenze 1948), proprio per documentare «la differenza anche stilistica fra questo componimento e i cantici di Romano» (II, p. 581).
