In this paper we examine the contributions of the Italian geometrical school to the Foundations of Projective Geometry. Starting from De Paolis' work we discuss some papers by Segre, Peano, Veronese, Fano and Pieri. In particular we try to show how a totally abstract and general point of view was clearly adopted by the Italian scholars many years before the publication of Hilbert's Grundlagen.We are particularly interested in the interrelations between the Italian and the German schools (mainly the influence of (...) Staudt's and Klein's works). We try also to understand the reason of the steady decline of the Italian school during the twentieth century. (shrink)

Epistles 10-14 of the Brethren of Purity focus on the foundations of logic, offering a tenth-century interpretation of the classic Aristotelian texts by scholars in Islamic civilization. This is the first critical edition, presenting the original Arabic text with a fully annotated English translation.

In human groups performing oscillatory tasks, it has been observed that the frequency of participants' oscillations reduces when compared to that acquired in solo. This experimental observation is not captured by the standard Kuramoto oscillators, often employed to model human synchronization. In this work, we aim at capturing this observed phenomenon by proposing three alternative modifications of the standard Kuramoto model that are based on three different biologically-relevant hypotheses underlying group synchronization. The three models are tuned, validated and compared against (...) experiments on a group synchronization task, which is a multi-agent extension of the so-called mirror game. (shrink)

Schopenhauer n’a jamais manqué une occasion de rendre hommage à Cabanis. L’œuvre du physiologiste français l’a encouragé à proposer une interprétation physiologique du transcendantal. Il y a par ailleurs trouvé une confirmation physiologique de sa métaphysique de la volonté.

Background and objective: Assuming the hypothesis that the general practitioner can and should be a key player in making end-of-life decisions for hospitalised patients, perceptions of GPs’ role assigned to them by hospital doctors in making withdrawal decisions for such patients were surveyed.Design: Questionnaire survey.Setting: Urban and rural areas.Participants: GPs.Results: The response rate was 32.2% , and it was observed that 70.8% of respondents believed that their participation in withdrawal decisions for their hospitalised patients was essential, whereas 42.1% believed that (...) the hospital doctors were sufficiently skilled to make withdrawal decisions without input from the GPs. Most respondents were found to believe that they had the necessary skills and enough time to participate in withdrawal decisions. The last case of treatment withdrawal in hospital for one of their patients was described by 40% of respondents, of whom only 40.0% believed that they had participated actively in the decision process. The major factors in the multivariate analysis were the GP’s strong belief that his or her participation was essential , information on admission of the patient given to the GP by the hospital department , rural practice , visit to the patient dying in hospital and a request by the family to be kept informed about the patient .Conclusion: Strong interest was evinced among GPs regarding end-of-life issues, as well as considerable experience of patients dying at home. As GPs are more closely corrected to patients’ families, they may be a good choice for third-party intervention in making end-of-life decisions for hospitalised patients. (shrink)

The manuscript Chisianus VII 240 (K) is an important witness for A. Donatus’ Commentum on Terence, unfortunately discovered only after the editorial work of P. Wessner. K was demonstrated to follow different sources in different sections of the Commentary, but, for the section containing the commentary on Andria, it derives from the Carnotensis, a codex deperditus with a good Donatian text. In this paper I pay attention to significant errors that join the Chisianus VII 240 with Λ, a group of (...) manuscripts that come from the Maguntinus, in order to demostrate that the most probable way of explaining these Bindefehler is the assumption of a deep process of contamination, probably due to Λ.

The article describes the fourteen passages of the encyclopaedia containing the word dawla. The Ikhwān introduce a cyclical conception of the alternation of ruling dynasties. After the dynasty of the evil reached its apex, the dynasty of the good begins when learned agree “on a unique school and a sole religion”. The Ikhwān introduce this as a wondrous event, close to become reality. This conception is linked to their vision in expectance of the legitimate rulers after the debasement of the (...) Family of the Prophet following Muḥammad’s death. The connection of these passages with the rituals described in Ep. 50 On the Various Kinds of Management (where political vision, astrology and magic are combined) might confirm the Ikhwān’s Ismā ‘īlī commitment.

This paper wants to demonstrate the not casual similarity between Plautus’Asinaria 205 and Terence’s Andria 545 arguing for the possibility that Plautus’Asinaria 205 was interpolated.

In the first act of Terence'sAndria, we find a dialogue between the old man Simo and Sosia, the freedman, with the former explaining why he has decided to arrange a false wedding for his young son Pamphilus. He has, in fact, learned that his son, despite being betrothed, has had a relationship with another girl and that—quite a serious matter—the fiancée's father, Chremes, has heard about the clandestine affair. In verses 144–9 Simo reports on the not-altogether friendly meeting he has (...) had with Chremes, who is furious about the complete disrespect that has been shown to his daughter; Simo's only defence is to attempt to deny the truth (146:ego illud sedulo negare factum).

En la Suma Teológica (II-II, q.181, a.3) y en el De Veritate, q.11, a.4, Tomás de Aquino aclara la naturaleza propia de la enseñanza dilucidando si ésta pertenece a la vida contemplativa o a la vida activa. Dentro de ello, el autor señala que el acto de enseñar tiene dos objetos: la cosa misma que es enseñada y, por otro lado, a quién la ciencia es comunicada. Según el primer objeto, la enseñanza es propia tanto de la vida contemplativa como (...) activa. Y, según el segundo, es sólo propia de la vida activa. Ahora bien, la finalidad de la enseñanza no consiste en la sola contemplación de una verdad, ya que ésta tiende a ser útil para el prójimo y, en ese sentido, la enseñanza cumple su fin cuando la verdad es comunicada y recibida por el auditor. De este modo, Tomás de Aquino afirma que la enseñanza pertenece principalmente a la vida activa. Por lo tanto, para analizar su naturaleza y su finalidad no es posible hacerlo sólo desde la teoría del conocimiento que la sustenta, es necesario también adentrarse en el acto de enseñar, el cual se vivencia ejemplarmente en la pedagogía de Cristo y en su propia experiencia como maestro.

This is the first critical edition of Epistles 15-21 of the Brethren of Purity, which explore the natural sciences and correspond to Aristotle's great works on philosophy of nature. Along with Epistle 22, "On Animals," Epistles 15-21 correspond to the corpus of Aristotle's great works on the philosophy of nature: Physica , De caelo , De generatione et corruption , and Meteorologica I-III . Meteorologica IV may correspond to Epistle 19 "On Minerals" (though no such Aristotelian work has reached us), (...) and Epistle 21 is a reminder of the works on plants written by Theophrastus, Aristotle's pupil, and onwards. Epistle 20, "On the Quiddity of Nature," is an exposition of Aristotelian doctrines, as well as of those of Neoplatonic origin; it opens the angelologic tradition, whose main representatives in Islamic philosophy were Ibn Sina (d. 1037) and Suhrawardi (d. 1191). Besides providing the necessary references to the works by Aristotle and other Greek authors, this book deals with various doctrines of Ismaili origin echoed in the treatises, foremost of which is the hierarchical representation of the three natural kingdoms, which corresponds to the hierarchy of human beings. The basis of human salvation is here seen in the relation between divine Artisan and human artisan, both of whom accomplish their works by actualizing their knowledge. As is known, although moral behaviour is one necessary condition, salvation cannot be reached without a thorough knowledge of the sciences described in the encyclopaedia. (shrink)

This is the first critical edition of Epistles 15-21 of the Brethren of Purity, which explore the natural sciences and correspond to Aristotle's great works on philosophy of nature. Carla Baffioni illuminates the Epistles' relation to Greek philosophy, with particular focus on various doctrines of Ismaili origin that are echoed in the treatises.

This volume presents Epistles 39-41 of the Epistles of the Brethren of Purity, which deal with the types of movement; causes and effects; and definitions and descriptions of things. the Ikhwan considers both the philosophical and spiritual value of these topics.

Mettant en perspective historique le parallèle entre sciences cognitives et phénoménologie, nous revenons sur « l’architecture ouverte », qui pour Bernstein expliquait la richesse du comportement à la lumière de la physiologie cérébrale. Sa conception de la « dextérité » sera interprétée en rapport à la « dégénérescence » du système nerveux au sens d’Edelman, de façon à mettre au jour les « contraintes dynamiques » entre l’environnement, le corps humain sensori-moteur et le cerveau. Les deux concepts renvoient, en effet, (...) à « l’ouverture » des processus mentaux et comportementaux, dont la plasticité conditionne l’adaptation de l’humain à son environnement. (shrink)

Purpose The purpose of this paper is to present the conceptual model of an innovative methodology (SAT) to assess the social acceptance of technology, especially focusing on artificial intelligence (AI)-based technology. -/- Design/methodology/approach After a review of the literature, this paper presents the main lines by which SAT stands out from current methods, namely, a four-bubble approach and a mix of qualitative and quantitative techniques that offer assessments that look at technology as a socio-technical system. Each bubble determines the social (...) variability of a cluster of values: User-Experience Acceptance, Social Disruptiveness, Value Impact and Trust. -/- Findings The methodology is still in development, requiring further developments, specifications and validation. Accordingly, the findings of this paper refer to the realm of the research discussion, that is, highlighting the importance of preventively assessing and forecasting the acceptance of technology and building the best design strategies to boost sustainable and ethical technology adoption. -/- Social implications Once SAT method will be validated, it could constitute a useful tool, with societal implications, for helping users, markets and institutions to appraise and determine the co-implications of technology and socio-cultural contexts. -/- Originality/value New AI applications flood today’s users and markets, often without a clear understanding of risks and impacts. In the European context, regulations (EU AI Act) and rules (EU Ethics Guidelines for Trustworthy) try to fill this normative gap. The SAT method seeks to integrate the risk-based assessment of AI with an assessment of the perceptive-psychological and socio-behavioural aspects of its social acceptability. (shrink)

Till the 1960s, social practices matched more or less the legal frame, staging a hierchical family with the complementary roles of the breadwinner and the housewife. Dramatic demographic and political changes have lead to a redefinition of parent roles. But this redifinition has remained largely confined to representations and symbols. The shift from a vision of gender complementarity – in the representations of parenthood – to a vision of gender equality seems to come to a halt in front of the (...) deep belief in the « incommensurable » difference between genders.

The Ikhwan al-Safa (Brethren of Purity), the anonymous adepts of a tenth-century esoteric fraternity based in Basra and Baghdad, hold an eminent position in the history of science and philosophy in Islam due to the wide reception and assimilation of their monumental encyclopaedia, the Rasa'il Ikhwan al-Safa ( Epistles of the Brethren of Purity ). This compendium contains fifty-two epistles offering synoptic accounts of the classical sciences and philosophies of the age; divided into four classificatory parts, it treats themes in (...) mathematics, logic, natural philosophy, psychology, metaphysics, and theology, in addition to didactic fables. The Rasa'il constitutes a paradigmatic legacy in the canonization of philosophy and the sciences in mediaeval Islamic civilization, as well as having shown a permeating influence in Western culture. The present volume is the second of this definitive series, consisting of the very first critical edition of the Rasa'il in its original Arabic, complete with the first fully annotated English translation. Prepared by Professor Carmela Baffioni, Epistles 10-14 comprise the foundations of logic, which remained a fundamental component in pedagogy until the twentieth century. The Ikhwan treat the Isagoge and the larger part of the Organon , both of which were circulating through the Islamic world at that time, as they set about detailing the ten categories of existents, the five predicables, and other such commonplaces of Aristotelian logic, including his seminal method of syllogistic inference. With the claim that logic is the noblest of man's arts, and man the noblest of creatures, the Ikhwan cast Aristotelian tropes in a spiritual light. (shrink)

Emerging evidence supports the role for the intracellular domains of amyloid precursor protein (APP) in the physiology and function of APP. In this short report, I discuss the hypothesis that mutation of Tyr682 on the Y682ENPTY687 C‐terminal motif of APP may be directly or indirectly associated with alterations in APP functioning and activity, leading to neuronal defects and deficits. Mutation of Tyr682 induces an early and progressive age‐dependent cognitive and locomotor decline that is associated with a loss of synaptic connections, (...) a decrease in cholinergic tone, and defects in NGF signaling. These findings support a model in which APP‐C‐terminal domain exerts a pathogenic function in neuronal development and decline, and suggest that Tyr682 potentially could modulate the properties of APP metabolites in humans.

Based on a new and complete collation of manuscripts and ancient editions, this paper will discuss some stemmatic and textual problems concerning the “Excerpta de comoedia” attributed to Aelius Donatus.

Heath and Tversky (1991, Journal of Risk and Uncertainty 4:5–28) posed that reaction to ambiguity is driven by perceived competence. Competence effects may be inconsistent with ambiguity aversion if betting on own judgement is preferred to betting on a chance event, because judgemental probabilities are more ambiguous than chance events. This laboratory experiment analyses whether ambiguity affects prices and volumes in a double auction market, and contrasts ambiguity aversion to competence effects. In order to test for the presence of competence (...) effects, in the experiment uncertainty is tied to the realisation of events about which the decision maker is more or less knowledgeable. Two experiments are presented: in the first, knowledge is exogenous, whereas in the second the knowledge judgement is endogenous. Market prices provide evidence in favour of the competence hypothesis only when competence is self-assessed. Comparable volumes are observed in both experiments. (shrink)

O presente artigo compara algumas características bem conhecidas do humanismo ocidental com aquelas do assim chamado “humanismo muçulmano” dos séculos X-XII. A “idade de ouro” muçulmana, em suas várias facetas, construiu-se sobre uma consistente, apesar de multifacetada, base religiosa. Razões históricas e culturais demonstram sempre que a ética não é suficiente a fim de estabelecer uma base comum para o diálogo com o Islã, e que é preciso aproximar- se dele principalmente pelo viés do pensamento religioso. O re-pensar do Livro (...) Sagrado sobre um novo fundamento, proposto por diversos membros da intelligentzia muçulmana, e que realça, assim, o antigo humanismo, deve, pois, ser levado em consideração pela contraparte ocidental. Já o Ocidente, pelo contrário, não pode cometer o erro de ler o texto do Islã de acordo com suas próprias atitudes históricas e/ou ideológicas. PALAVRAS-CHAVE – Humanismo islâmico. Humanismo ocidental. Diálogo de culturas. Religião. (shrink)
