This article reports on the development of the managerial ethical profile (MEP) scale. The MEP scale is a multilevel, self-reporting scale measuring the perceived influence that different dimensions of common ethical frameworks have on managerial decision making. The MEP scale measures on eight subscales: economic egoism, reputational egoism, act utilitarianism, rule utilitarianism, self-virtue of self, virtue of others, act deontology, and rule deontology. Confirmatory factor analysis (CFA) was used to provide evidence of scale validity. Future research needs and the value (...) of this measure for business ethics are discussed. (shrink)

Background:Ambulance professionals often address conflicts between ethical values. As individuals’ values represent basic convictions of what is right or good and motivate behaviour, research is needed to understand their value profiles.Objectives:To translate and adapt the Managerial Values Profile to Spanish and Swedish, and measure the presence of utilitarianism, moral rights and/or social justice in ambulance professionals’ value profiles in Spain and Sweden.Methods:The instrument was translated and culturally adapted. A content validity index was calculated. Pilot tests were carried out with 46 (...) participants.Ethical considerations:This study conforms to the ethical principles for research involving human subjects and adheres to national laws and regulations concerning informed consent and confidentiality.Findings:Spanish professionals favoured justice and Swedish professionals’ rights in their ambulance organizations. Both countries favoured utilitarianism least. Gender differences across countries showed that males favoured rights. Spanish female professionals favoured justice most strongly of all.Discussion:Swedes favour rights while Spaniards favour justice. Both contexts scored low on utilitarianism focusing on total population effect, preferring the opposite, individualized approach of the rights and justice perspectives. Organizational investment in a utilitarian perspective might jeopardize ambulance professionals’ moral right to make individual assessments based on the needs of the patient at hand. Utilitarianism and a caring ethos appear as stark opposites. However, a caring ethos in its turn might well involve unreasonable demands on the individual carer’s professional role. Since both the justice and rights perspectives portrayed in the survey mainly concern relationship to the organization and peers within the organization, this relationship might at worst be given priority over the equal treatment and moral rights of the patient.Conclusion:A balanced view on ethical perspectives is needed to make professionals observant and ready to act optimally – especially if these perspectives are used in patient care. Research is needed to clarify how justice and rights are prioritized by ambulance services and whether or not these organization-related values are also implemented in patient care. (shrink)

- L'articolo assume come sfondo specifico le dinamiche della relazione uomo-natura in John Dewey, cercando di ricostruire in chiave drammatica il problema della personalitÀ individuale. Attraverso l'utilizzo di un metodo di tipo fenomenologico, vengono messe in luce le tappe che conducono l'individuo a un processo di realizzazione etica di sé. Particolare risalto viene dato al dramma che il soggetto vive nella scelta razionale dei valori. Dramma che induce il filosofo americano a trovare nell'etica lo sviluppo finale della logica. Questa svolta (...) muove l'intero processo della soggettivitÀ sul piano della responsabilitÀ. Una responsabilitÀ drammatica e rischiosa, che costituisce l'unica via che il soggetto puň percorrere se aspira a qualificare la realtÀ in cui si trova inscindibilmente incarnato in modo intelligente, personale e creativo.

Obiettivo del saggio č di esplorare se esista la possibilitÀ di una organizzazione logico-razionale della realtÀ, a partire dalle riflessioni che su questo tema Alfred Schütz ha proposto in. Si mostra come per Schütz non risulti affatto agevole un'applicazione dei principi della logica tradizionale alle dinamiche che caratterizzano la realtÀ quotidiana. Soltanto attraverso le categorie tipizzanti proprie della scienza l'osservatore potrÀ «far tornare i conti» di una realtÀ che altrimenti non potrebbe apparire perfettamente logica, non mettendo cosě in discussione la (...) validitÀ del metodo razionale, ma d'altro canto pagando il prezzo di ridurre il mondo sociale a un teatro di. Una sorta di «burattini semi-animati» che eseguono in modo coerente e razionale tutto ciň che le categorie tipologiche della scienza, dall'alto della loro dimensione puramente concettuale, impongono loro.

A partire da testi profondamente diversi come il Canzoniere petrarchesco e una raccolta di scritti autobiografici di pazienti oncologiche, l'autore compie un'indagine sul concetto di speranza, in particolare sulla sua dimensione temporale e sulla sua connessione con l'attivazione del pensiero. Con riferimenti teorici eterogenei che vanno da Bloch a Borgna, da Minkowski a Marcel, da Demetrio a Bénasayag e Schmit, dalla psicoanalisi alla teologia biblica e alla sociologia, si indagano gli aspetti regressivi e quelli evolutivi della speranza considerata come proiezione (...) del futuro nel presente che influisce sull'elaborzione del proprio passato personale. Infine si osserva come il tempo della contemporaneitÀ sia impermeabile alla speranza, che sopravvive solo in ambiti quali la scrittura, la creativitÀ, la lentezza, il silenzio nei quali ci si puň ancora prendere cura di sé.

Riassunto : Gli autori di autoritratti fotografici possono esprimere diversi aspetti della loro personalità. In particolare, i selfie enfatizzano difficoltà nella connessione cervello-corpo, una fantasia di auto creazione e il bisogno di rimuovere qualsiasi mediazione nella creazione di un’immagine personale. Il fine della pubblicazione di un selfie non nasce dal bisogno di una relazione reale, ma deriva dalla necessità di un’auto-conferma narcisistica. Il pensiero che si produce quando una persona scatta e condivide un selfie esclude la mentalizzazione e non è (...) orientato verso il mondo interno individuale, ma si concentra su un pensiero di auto-rispecchiamento della persona che lo posta. I selfie non rivelano solo livelli variabili di narcisismo dell’autore, a seconda delle tipologie di selfie, ma possono essere segni di alcuni tratti di personalità schizoide, dipendente, istrionica, evitante e anche in alcuni casi borderline. Parole chiave : Selfie; Narcisismo; Autorappresentazione; Rapporto corpo/mente; Social network; Comunicazione Selfie: Hidden Thoughts, Self-creation Fantasy, Personality Traits: Self-portrait photographs can express different aspects of the author’s personality. In particular, selfies magnify difficulties with the brain-body connection, self-creation fantasies and a felt need to remove any mediation involved in the creation of a personal image. The impulse to publish selfies does not stem from a need for real relationships, but rather serves narcissistic self-confirmation. When a person takes and shares a selfie, she avoids mentalisation and does not orient towards her internal world, but instead focuses on self-mirroring the posing person. Selfies not only reveal the variable shades of the author’s narcissism, depending on the typology of the selfie, but can also reveal signs of certain schizoid, dependent, histrionic, avoidant, and sometimes even borderline personality traits. Keywords: Selfies; Narcissism; Self-representation; Mind/Body Relationship; Social Network; Communication. (shrink)

Il saggio analizza il modo in cui l'uso dell'sms favorisce una modalitÀ di pseudo-attivazione del pensiero che ha ricadute sulle rappresentazioni di sé, dell'altro e delle relazioni tra sé e l'altro. In quanto «tecnologia del sé», il telefonino orienta e modifica il pensiero in una direzione narcisistica e autocentrata per cui gran parte delle comunicazioni ha una ricaduta autoreferenziale e la persona con cui ci si relaziona č ridotta a oggetto-Sé con funzione speculare di conferma dell'immagine che il soggetto ha (...) di se stesso. Il risultato č la creazione di pseudo-pensieri e una mentalizzazione di superficie che porta spesso a un'identificazione fusionale con l'altro, non riconosciuto come effettivamente altro da sé. Si realizzano quelle «identificazioni solide» di cui parla Recalcati che si connettono all'abolizione dell'inconscio da lui riscontrata nella nostra epoca. (shrink)

We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of the combination of prototypical concepts. The proposed logic relies on the logic of typicality ALC + TR, whose semantics is based on the notion of rational closure, as well as on the distributed semantics of probabilistic Description Logics, and is equipped with a cognitive heuristic used by humans for concept composition. We first extend the logic of typicality ALC + TR by typicality inclusions of the (...) form p :: T(C) v D, whose intuitive meaning is that “we believe with degree p about the fact that typical Cs are Ds”. As in the distributed semantics, we define different scenarios containing only some typicality inclusions, each one having a suitable probability. We then exploit such scenarios in order to ascribe typical properties to a concept C obtained as the combination of two prototypical concepts. We also show that reasoning in the proposed Description Logic is EXPTIME-complete as for the underlying standard Description Logic ALC. (shrink)

We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of combining prototypical concepts, an open problem in the fields of AI and cognitive modelling. Our logic extends the logic of typicality ALC + TR, based on the notion of rational closure, by inclusions p :: T(C) v D (“we have probability p that typical Cs are Ds”), coming from the distributed semantics of probabilistic Description Logics. Additionally, it embeds a set of cognitive heuristics for concept (...) combination. We show that the complexity of reasoning in our logic is EXPTIME-complete as in ALC. (shrink)

In this paper we focus on theorem proving for conditional logics. First, we give a detailed description of CondLean, a theorem prover for some standard conditional logics. CondLean is a SICStus Prolog implementation of some labeled sequent calculi for conditional logics recently introduced. It is inspired to the so called “lean” methodology, even if it does not fit this style in a rigorous manner. CondLean also comprises a graphical interface written in Java. Furthermore, we introduce a goal-directed proof search mechanism, (...) derived from the above mentioned sequent calculi based on the notion of uniform proofs. Finally, we describe GOALDUCK, a simple SICStus Prolog implementation of the goal-directed calculus mentioned here above. Both the programs CondLean and GOALDUCK, together with their source code, are available for free download at. (shrink)

Résumé Depuis plusieurs années, habitants et militants de la vallée de Suse s’opposent à la construction d’une ligne à grande vitesse entre la France et l’Italie. La réaction des autorités est quasi-militaire mais le faible avancement des travaux ne justifie pas un tel emportement. La lutte expérimente pas à pas les nouveaux concepts de la construction du commun.

Combining typical knowledge to generate novel concepts is an important creative trait of human cognition. Dealing with such ability requires, from an AI perspective, the harmonization of two conflicting requirements that are hardly accommodated in symbolic systems: the need of a syntactic compositionality (typical of logical systems) and that one concerning the exhibition of typicality effects (see Frixione and Lieto, 2012). In this work we provide a logical framework able to account for this type of human-like concept combination. We propose (...) a nonmonotonic Description Logic of typicality called TCL (Typicality-based Compositional Logic). (shrink)

In this paper we present a framework for the dynamic and automatic generation of novel knowledge obtained through a process of commonsense reasoning based on typicality-based concept combination. We exploit a recently introduced extension of a Description Logic of typicality able to combine prototypical descriptions of concepts in order to generate new prototypical concepts and deal with problem like the PET FISH (Osherson and Smith, 1981; Lieto & Pozzato, 2019). Intuitively, in the context of our application of this logic, the (...) overall pipeline of our system works as follows: given a goal expressed as a set of properties, if the knowledge base does not contain a concept able to fulfill all these properties, then our system looks for two concepts to recombine in order to extend the original knowledge based satisfy the goal.

The relationship between traumatic life events and increased suicide risk has been well reported in literature. However, the complex nature of suicidality phenomena still hinders our ability to comprehend the mediation mechanism underlying this association. In this study, we examined the mediating role of adult attachment and reflective functioning in the relationship between traumatic life events and suicidal ideation. Nine hundred and fifty Italian adults completed an online survey evaluating traumatic life events, adult attachment, reflective functioning and suicidal ideation. The (...) path analysis showed that the positive relationship between traumatic life events and suicidal ideation was partially mediated by attachment anxiety and reflective functioning. From a clinical point of view, these results support the relevance of evaluating and improving patients’ ability to mentalize as a part of psychotherapeutic intervention aimed at reducing suicidality in people with a history of traumatic experiences and attachment anxiety.

Clinical Ethics Committees (CECs), as distinct from Research Ethics Committees, were originally established with the aim of supporting healthcare professionals in managing controversial clinical ethical issues. However, it is still unclear whether they manage to accomplish this task and what is their impact on clinical practice. This systematic review aims to collect available assessments of CECs’ performance as reported in literature, in order to evaluate CECs’ effectiveness. We retrieved all literature published up to November 2019 in six databases (PubMed, Ovid (...) MEDLINE, Scopus, Philosopher’s Index, Embase and Web of Science), following PRISMA guidelines. We included only articles specifically addressing CECs and providing any form of CECs performance assessment. Twenty-nine articles were included. Ethics consultation was the most evaluated of CECs’ functions. We did not find standardized tools for measuring CECs’ efficacy, but 33% of studies considered “user satisfaction” as an indicator, with 94% of them reporting an average positive perception of CECs’ impact. Changes in patient treatment and a decrease of moral distress in health personnel were reported as additional outcomes of ethics consultation. The highly diverse ways by which CECs carry out their activities make CECs’ evaluation difficult. The adoption of shared criteria would be desirable to provide a reliable answer to the question about their effectiveness. Nonetheless, in general both users and providers consider CECs as helpful, relevant to their work, able to improve the quality of care. Their main function is ethics consultation, while less attention seems to be devoted to bioethics education and policy formation. (shrink)

In Posterior Analytics 71b9 12, we find Aristotle’s definition of scientific knowledge. The definiens is taken to have only two informative parts: scientific knowledge must be knowledge of the cause and its object must be necessary. However, there is also a contrast between the definiendum and a sophistic way of knowing, which is marked by the expression “kata sumbebekos”. Not much attention has been paid to this contrast. In this paper, I discuss Aristotle’s definition paying due attention to this contrast (...) and to the way it interacts with the two conditions presented in the definiens. I claim that the “necessity” condition ammounts to explanatory appropriateness of the cause. (shrink)

We present an axiomatic approach for a class of finite, extensive form games of perfect information that makes use of notions like “rationality at a node” and “knowledge at a node.” We distinguish between the game theorist's and the players' own “theory of the game.” The latter is a theory that is sufficient for each player to infer a certain sequence of moves, whereas the former is intended as a justification of such a sequence of moves. While in general the (...) game theorist's theory of the game is not and need not be axiomatized, the players' theory must be an axiomatic one, since we model players as analogous to automatic theorem provers that play the game by inferring (or computing) a sequence of moves. We provide the players with an axiomatic theory sufficient to infer a solution for the game (in our case, the backwards induction equilibrium), and prove its consistency. We then inquire what happens when the theory of the game is augmented with information that a move outside the inferred solution has occurred. We show that a theory that is sufficient for the players to infer a solution and still remains consistent in the face of deviations must be modular. By this we mean that players have distributed knowledge of it. Finally, we show that whenever the theory of the game is group-knowledge (or common knowledge) among the players (i.e., it is the same at each node), a deviation from the solution gives rise to inconsistencies and therefore forces a revision of the theory at later nodes. On the contrary, whenever a theory of the game is modular, a deviation from equilibrium play does not induce a revision of the theory. (shrink)

In the Aeneid, Virgil sets out to achieve a new sublime style, paradoxically steeped in the common parlance. He aims for the spontaneity of everyday language to win readers’ involvement, while elaborating a discourse both expressively taut and stylistically marked, that avoids a register too colloquial or prosaic. Above all, he tirelessly deploys an array of subtle strategies – below the threshold of perception – that defamiliarize language in order to elevate its style. The present paper furnishes a selection of (...) case studies. (shrink)

In this paper we apply the idea of Revision Rules, originally developed within the framework of the theory of truth and later extended to a general mode of definition, to the analysis of the arithmetical hierarchy. This is also intended as an example of how ideas and tools from philosophical logic can provide a different perspective on mathematically more “respectable” entities. Revision Rules were first introduced by A. Gupta and N. Belnap as tools in the theory of truth, and they (...) have been further developed to provide the foundations for a general theory of (possibly circular) definitions. Revision Rules are non-monotonic inductive operators that are iterated into the transfinite beginning with some given “bootstrapper” or “initial guess.” Since their iteration need not give rise to an increasing sequence, Revision Rules require a particular kind of operation of “passage to the limit,” which is a variation on the idea of the inferior limit of a sequence. We then define a sequence of sets of strictly increasing arithmetical complexity, and provide a representation of these sets by means of an operator G(x, φ) whose “revision” is carried out over ω2 beginning with any total function satisfying certain relatively simple conditions. Even this relatively simple constraint is later lifted, in a theorem whose proof is due to Anil Gupta. (shrink)

I discuss what Aristotle means when he say that scientific demonstration must proceed from necessary principles. I argue that, for Aristotle, scientific demonstration should not be reduced to sound deduction with necessary premises. Scientific demonstration ultimately depends on the fully appropriate explanatory factor for a given explanandum. This explanatory factor is what makes the explanandum what it is. Consequently, this factor is also unique. When Aristotle says that demonstration must proceed from necessary principles, he means that each demonstration requires the (...) principle that is the necessary one for the fully appropriate explanation of its explanandum. This picture also provides a key to understand Aristotle's thesis that scientific explanation depends on essences: it is the essence of the attribute to be explained that should be stated as the fully appropriate explanatory factor.

Analyzing geometric properties of high-dimensional loss functions, such as local curvature and the existence of other optima around a certain point in loss space, can help provide a better understanding of the interplay between neural network structure, implementation attributes, and learning performance. In this work, we combine concepts from high-dimensional probability and differential geometry to study how curvature properties in lower-dimensional loss representations depend on those in the original loss space. We show that saddle points in the original space are (...) rarely correctly identified as such in expected lower-dimensional representations if random projections are used. The principal curvature in the expected lower-dimensional representation is proportional to the mean curvature in the original loss space. Hence, the mean curvature in the original loss space determines if saddle points appear, on average, as either minima, maxima, or almost flat regions. We use the connection between expected curvature in random projections and mean curvature in the original space (i.e., the normalized Hessian trace) to compute Hutchinson-type trace estimates without calculating Hessian-vector products as in the original Hutchinson method. Because random projections are not suitable to correctly identify saddle information, we propose to study projections along dominant Hessian directions that are associated with the largest and smallest principal curvatures. We connect our findings to the ongoing debate on loss landscape flatness and generalizability. Finally, for different common image classifiers and a function approximator, we show and compare random and Hessian projections of loss landscapes with up to about 7×10^6 parameters. (shrink)

It has been observed that whereas painters and musicians are likely to be embarrassed by references to the beauty in their work, mathematicians instead like to engage in discussions of the beauty of mathematics. Professional artists are more likely to stress the technical rather than the aesthetic aspects of their work. Mathematicians, instead, are fond of passing judgment on the beauty of their favored pieces of mathematics. Even a cursory observation shows that the characteristics of mathematical beauty are at variance (...) with those of artistic beauty. For example, courses in art appreciation are fairly common; it is however unthinkable to find any mathematical beauty appreciation courses taught anywhere. The purpose of the present paper is to try to uncover the sense of the term beauty as it is currently used by mathematicians. (shrink)

Aristotle contrasts episteme and doxa through the key notions of universal and necessary. These notions have played a central role in Aristotle’s characterization of scientific knowledge in the previous chapters of APo. They are not spelled out in APo I.33, but work as a sort of reminder that packs an adequate characterization of scientific knowledge and thereby gives a highly specified context for Aristotle’s contrast between episteme and doxa. I will try to show that this context introduces a contrast in (...) terms of explanatory claims: on the one hand, episteme covers those claims which capture explanatory connections that are universal and necessary and thereby deliver scientific understanding; on the other hand, doxa covers the explanatory attempts that fail at doing so.
