AimThe Coronavirus 2019 pandemic represents one of the most catastrophic events of recent times. Due to the hospitals’ emergency situation, the population of healthcare workers was the most affected. Healthcare workers who were exposed to COVID-19 patients are most likely to develop psychological distress and post-traumatic stress disorder. The present study aimed at investigating PTSD in a sample of Italian healthcare workers during this outbreak and to evaluate the effectiveness of the Eye Movement Desensitization and Reprocessing Therapy with this population.MethodsA (...) total of 744 healthcare workers were included. 587 healthcare workers were treated with EMDR, while the other 157 were not treated. Participants were asked to provide sociodemographic information; the post-traumatic symptomatology was evaluated through Impact of Event Scale-Revised and to investigate the level of intensity of emotional activation was used The Emotion Thermometer at two time points.ResultsThe results obtained between EMDR treatment and non-EMDR treatment were evaluated on only 2 hospitals. Treatment group n = 68 vs. waitlist non-treatment group n = 157. All scores pre- and post-EMDR decreased significantly showing an evident effect of EMDR. The differences between pre- and post-treatment of the IES-R scores of subjects in which EMDR was performed as compared to the scores pre- and post-12 weeks of waiting list subjects in which it was not performed were significantly different.LimitationThe emergency situation did not provide an opportunity to explore further aspects that would have been important for research. One limitation is the use and analysis of only two standardized tests. In addition, other psychopathologies were not investigated as outcome measures. A limitation is the comparison of subjects treated online and de visu. Although the protocol used was the same, the mode of intervention may have influenced the results. In addition, the effectiveness of EMDR treatment was only evaluated at two time points with no possibility of follow-up and the lack of a control group.Discussion/conclusionThe findings of the present study suggest that healthcare workers were at high risk of developing PTSD when confronted with COVID-19 outbreak and suggest the importance of psychological support during this humanitarian emergency.

Open futurism is the indeterministic position according to which the future is ‘open’, i.e., there is now no fact of the matter as to what future contingent events will actually obtain. Many open futurists hold a branching conception of time, in which a variety of possible futures exist. This paper introduces two challenges to branching-time open futurism, which are similar in spirit to a challenge posed by Fine to tense realism. The paper argues that, to address the new challenges, open (...) futurists must adopt an objective, non-perspectival notion of actuality and subscribe to an A-theoretic, dynamic conception of reality. Moreover, given a natural understanding of “actual future”, it is perfectly sensible for open futurists to hold that a unique, objectively actual future exists, contrary to a common assumption in the current debate. The paper also contends that recognising the existence of a unique actual future helps open futurists to avoid potential misconceptions. (shrink)

We present a general approach to quantified modal logics that can simulate most other approaches. The language is based on operators indexed by terms which allow to express de re modalities and to control the interaction of modalities with the first-order machinery and with non-rigid designators. The semantics is based on a primitive counterpart relation holding between n-tuples of objects inhabiting possible worlds. This allows an object to be represented by one, many, or no object in an accessible world. Moreover (...) by taking as primitive a relation between n-tuples we avoid some shortcoming of standard individual counterparts. Finally, we use cut-free labelled sequent calculi to give a proof-theoretic characterisation of the quantified extensions of each first-order definable propositional modal logic. In this way we show how to complete many axiomatically incomplete quantified modal logics. (shrink)

Safety-critical systems manufacturers have the duty of care, i.e., they should take correct steps while performing acts that could foreseeably harm others. Commonly, industry standards prescribe reasonable steps in their process requirements, which regulatory bodies trust. Manufacturers perform careful documentation of compliance with each requirement to show that they act under acceptable criteria. To facilitate this task, a safety-centered planning-time framework, called ACCEPT, has been proposed. Based on compliance-by-design, ACCEPT capabilities permit to design Compliance-aware Engineering Process Plans, which are able (...) to show the planning-time allocation of standard demands, i.e., if the elements set down by the standard requirements are present at given points in the engineering process plan. In this paper, we perform a case study to understand if the ACCEPT produced models could support the planning of space software engineering processes. Space software is safety and mission-critical, and it is often the result of industrial cooperation. Such cooperation is coordinated through compliance with relevant standards. In the European context, ECSS-E-ST-40C is the de-facto standard for space software production. The planning of processes in compliance with project-specific ECSS-E-ST-40C applicable requirements is mandatory during contractual agreements. Our analysis is based on qualitative criteria targeting the effort dictated by task demands required to create a CaEPP for software development with ACCEPT. Initial observations show that the effort required to model compliance and processes artifacts is significant. However, such an effort pays off in the long term since models are, to some extend, reusable and flexible. The coverage level of the models is also analyzed based on design decisions. In our opinion, such a level is adequate since it responds to the information needs required by the ECSS-E-ST-40C framework. (shrink)

Norms conferring public or private powers, i.e., the competence to issue other norms, play a very important rôle in law. But there is no agreement among legal philosophers about the nature of such norms. There are two main groups of theories, those that regard them as a kind of norms of conduct (either commands or permissions) and those that regard them as non-reducible to other types of norms. I try to show that reductionist theories are not quite acceptable; neither the (...) command-variety (Kelsen, Alf Ross inOn Law and Justice), nor the permission-variety (von Wright, Kanger, Lindahl) provide a satisfactory account of competence norms.Among the authors who maintain that competence norms are different from (and hence not reducible to) norms of conduct are Hart, Ross inDirectives and Norms, and Searle. Ross and Searle distinguish between regulative and constitutive rules as two radically different kinds of rules and classify competence norms among constitutive rules. This distinction runs parallel to von Wright's distinction between rules that are prescriptions and determinative rules. While the first regulate actions (by commanding, prohibiting, or permitting them), determinative rules define certain concepts. To view competence norms as (partial) definitions of certain legal concepts (like those of legislator, judge, etc.) seems to open interesting perspectives and to shed light on at least one aspect of these elusive norms.

The thin red line theory is a form of branching indeterminism. It entails that, among the many possible developments that reality might take, one is privileged: the actual history. The thin red line theory is naturally paired off with a semantic thesis that may be called ‘the actuality principle’: a statement is true as used at a moment if and only if it is true at that moment on the actual history. The actuality principle has been challenged, for it would (...) be wrong about several counterfactual reasonings. On the one hand, the actuality principle should entail that any statement uttered at a merely possible moment is untrue. On the other hand, the actuality principle should be at odds with the way we use subjunctive conditionals. This paper argues that both objections rely on an inadequate understanding of the notion of the history of use. As for the first objection, the paper argues that to assume the actuality principle amounts to taking the actual history as the history of use. As a consequence, one cannot consistently take the actual history as the history of use and, at the same time, a merely possible moment as the moment of use. As for the second objection, the paper shows that the actuality principle is consistent with any reasonable treatment of subjunctive conditionals. (shrink)

This paper reports a psychological study of human categorization that looked at the procedures used by expert scientists when dealing with puzzling items. Five professional botanists were asked to specify a category from a set of positive and negative instances. The target category in the study was defined by a feature that was unusual, hence situations of uncertainty and puzzlement were generated. Subjects were asked to think aloud while solving the tasks, and their verbal reports were analyzed. A number of (...) problem solving strategies were identified, and subsequently integrated in a model of knowledge‐guided inductive categorization. Our model proposes that expert knowledge influences the subjects' reasoning in more complex ways than suggested by earlier investigations of scientific reasoning. As in previous studies, domain knowledge influenced our subjects' hypothesis generation and testing; but, additionally, it played a central role when subjects revised their hypotheses. (shrink)

In 1911 the Wilson cloud chamber opened new possibilities for physics pedagogy. The instrument, which visualized particles’ tracks as trails of condensed vapour, was adopted by physicists to pursue frontier research on the Compton effect, the positron and the transmutation of atomic nuclei. But as the present paper will show, Wilson's instrument did not just open up new research opportunities, but the possibility of developing a different kind of teaching. Equipped with a powerful visualization tool, some physicists–teachers employed Wilson's instrument (...) to introduce their students to a wide range of phenomena and concepts, ranging from the behaviour of clouds to Einstein's photon, the wave–particle duality and the understanding of the nucleus. This paper uses the notes, books and prototypes of these pioneering physicists–teachers to compose a pedagogical history of the Wilson cloud chamber, documenting an episode of immense ingenuity, creativity and scientific imagination.

This article moves from the observation that one of the key characteristics of contemporary Italian fiction is a preoccupation with ethics and more specifically with the issues raised by the “ethical turn” in contemporary philosophy and theory. Current literary criticism, it is argued, has been slow to respond to the ethical dimension of these narratives whose innovative and important cultural contribution has yet to be fully appreciated. It is therefore necessary to develop a keener sensitivity to the ethical discourses developed (...) in these literary texts, but this can only be achieved by first confronting some fundamental questions about the relationship between ethics and literature today. The answers to these questions make it possible to elaborate an initial conceptual framework that can re-orient reading and enable the critic to respond adequately to the ethical issues raised in and by the narrative. Accordingly, in this article the author proposes to explore from a theoretical perspective the relationship between ethics and literature in the context of the historical and philosophical predicaments of contemporary society. The discussion is divided into two parts: the first is devoted to an exploration of contemporary ethical thinking, and the second on the contribution that literature can make to that thinking. In the first part, the author proposes an approach to ethics based on the virtue tradition which, since Aristotle, has defined ethics as the search for "the good life." This tradition, however, is transformed through an engagement with the work of Gilles Deleuze and Immanuel Levinas. From Deleuze the author draws the idea that the good life is one devoted to pursuing human plenitude through the multiplication of connections and intensities. From Levinas, on the other hand, emerges a powerfully haunting description of an ethical life marked by absolute responsibility for and obligation to the other. These two seemingly opposed views are not construed as irreconcilable and contradictory but rather as vectors which keep opposing tensions in check and ultimately define a necessary negotiation between the desire for human plenitude and the acknowledgement of responsibility for other human and non human life. Ultimately my argument is that such tensions establish the ethical terrain in which contemporary narratives seek to intervene. In the second part of the article, the nature and possibilities of such an intervention are explored through six theses which provocatively articulate the relationship between literature and ethics. The cornerstone thesis is that literature is an encounter. Each subsequent thesis endeavours to develop this initial assertion and explore its consequences. The theses are accompanied by a gloss which unfolds its meaning and significance: the answers that the given thesis provides but also the questions that it raises. Together, the theses provide a heuristic framework for a literary criticism sensitive to ethical issues and therefore capable of grappling with the important cultural work carried out in fictions that have struggled to receive the recognition they deserve.

Des influences égyptiennes dans la Descriptio orbis de Denys d’Alexandrie ? L’examen attentif des composantes laudatives et du contenu du proème de la Descriptio orbis de Denys le Périégète prouve que le poète originaire d’Alexandrie a été influencé dans son œuvre même par la religion égyptienne. En particulier, derrière l’éloge de l’Océan paraît se cacher un hymne à la louange du Nun primordial.Egyptian Influences in the Descriptio orbis by Dionysius of Alexandria? The thorough analysis of the laudatory components and contents (...) of the proem by Dionysius Periegetes’ Descriptio orbis shows that the Alexandrian poet was also influenced in his own poem by the Egyptian religion. In particular, behind the encomium of the Ocean, it looks as if the poet is hiding a hymn to the primeval Nun. (shrink)

Introduzione Nel codice della sua Bibliotheca consacrato a recensire la produzione letteraria di Temistio, il patriarca Fozio testimonia di aver letto – oltre ad alcune opere filosofiche – un corpus di trentasei discorsi politici (λόγοι πολιτιϰοιλς), tra cui alcuni indirizzati a Costanzo, a Valente e Valentiniano II, a Teodosio, non tutti pervenuti. Ora, l'opera oratoria di Temistio, quale noi moderni leggiamo, comprende trentatrè orazioni, pubbliche e private, di cui due (o forse tre) incomplete. È molto probabile che gli altri tre (...) discorsi che Fozio ugualmente leggeva siano da identificare con orazioni perdute, di cui sopravvivono talune notizie: il discorso recitato nel 357 dinanzi al senato di Costantinopoli in occasione di un'ambasceria a Roma, il panegirico indirizzato nel 363 all'imperatore Giuliano per il suo quarto consolato e l'orazione sulla tolleranza religiosa indirizzata a Valente tra gli anni 375–376. Verrebbe, in questo modo, confermata la notizia della Bibliotheca circa l'esistenza di un corpus di complessivi trentasei discorsi ed in particolare rafforzata l'ipotesi, ventilata da taluni studiosi, secondo cui la silloge temistiana in nostro possesso corrisponderebbe in buona sostanza al ‘libro’ recensito da Fozio.

En este texto, presento a Lamarck, como un autor que debe ser considerado, no solo como uno de fundadores de la biología, sino uno de los precursores del positivismo. Se examinarán nociones de “fuerza vital”, organización, “plan de la naturaleza”, “sentimiento interior” y hábito, pilares de su teoría de la transformación. Esta teoría fusiona el determinismo inherente al “plan de la naturaleza” (PN) con el papel más flexible del “sentimiento interior” (SI) y el hábito en la modificación. Es así como, (...) Lamarck defendió un holismo materialista que justifica la imagen de una naturaleza que, al organizar la materia, da lugar a la generación espontánea de seres vivos simples que a lo largo del tiempo se transforman incrementando los grados de organización, culminando con la aparición del hombre. Idea que Comte extrapoló para justificar un progreso social atado a la aparición de las ciencias positivas. Este trabajo también evalúa la crítica de Comte a Lamarck acerca del papel del medioambiente, cuyo potencial de cambio estaría limitado por “la existencia de “obstáculos interiores” a la modificación, superados en los humanos mediante la emergencia de la sociedad. Ambos autores estuvieron influenciados por François Quesnay, quien propugnaba una sociedad regida por una ética basada en una ley natural biológica. Pero, mientras Lamarck anticipaba el riesgo de la autoextinción humana, Comte consideraba que el verdadero progreso se lograría al convertir esa ley natural en fundamento de una nueva religión secular.

Some important ideas in Kelsen's Pure Theory of Law can be traced back to Kantian tradition, which has been very influential in Kelsen's thought, particularly in his early period. Among them we find the distinction between two radically different worlds (the world of facts and the world of norms), the normativity of legal science and the idea of validity as a binding force, based on the famous doctrine of the basic norm. These tenets and, especially, the use of a normative (...) concept of validity prove to be incompatible with Kelsen's positivistic programme of a value‐free legal science. The science of law cannot state that legal norms are obligatory or binding without trespassing the limits of Kelsen's ideal of a legal science; on the other hand, it is possible to define the concept of a legal system without resorting to the basic norm. So, if Kelsen is to be regarded as a consequent positivist, the Kantian ingredients of his theory must be rejected and the descriptive concept of validity as membership must be substituted for the normative notion of validity as a binding force.

This paper criticizes Alexy's argument on the necessary connection between law and morality. First of all, the author discusses some aspects of the notion of the claim to correctness. Basically, it is highly doubtful that all legal authorities share the same idea of moral correctness. Secondly, the author argues that the claim to correctness is not a defining characteristic of the concepts of “legal norm” and “legal system”. Hence, the thesis of a necessary connection between law and morality based on (...) such claim cannot be accepted. (shrink)

In this work I argue that Descartes was not a trialist by showing that the main tenets of trialist interpretations of Descartes's theory of substance are either not supported by the text or are not sufficient for establishing the trialist interpretation.

In Republic VI 508e-9b Plato has Socrates claim that the Good is the cause (αίτίαν) of truth and knowledge as well as the very being of the Forms. Consequently, as causes must be distinct from and superior to their effects, the Good is neither truth nor knowledge nor even being, but exceeds them all in beauty (509a), as well as in honour and power (509b). No other passage in Plato has had a more intoxicating effect on its readers. To take (...) just one example, James Adam was moved to quote St. Paul when he remarked about this passage that, 'it is highly characteristic of Plato's whole attitude that he finds the true keystone of the Universe — the ultimate fountain from which both Knowledge and Existence flow — in no cold and colourless ontological abstraction, like Being, but in that for which "all creation groans and labours".

Em 1630 Descartes declarou que os seus estudos estavam voltados para o estabelecimento dos fundamentos do conhecimento. Várias questões discutidas nas cartas são significativas, mas uma em particular é de grande importância para a compreensão da sua filosofia, a saber, a afirmação do fundamento metafísico das verdades eternas.

We intended to present in this work an approximation between Gilles Deleuze’s philosophy and Hume’s. Firstly we will show that Deleuze, in his reading of Hume, emphasizes empiricism’s importance for philosophy, though an empiricism distinct from the one offer by the philosophical tradition. We will further intend to show that these two authors share a common set of perspectives, namely, that thinking happens in response to an event, that “relation” is the instance that prompts thinking, and that the latter presents (...) himself as an experience.

Neste artigo pretendo apresentar uma interpretação do sentido que Espinosa atribuiu ao conceito de “vontade”. Mostrar como ele se afastou da concepção que a tradição tinha desse conceito, e qual é o papel que o mesmo desempenha nas deduções geométricas empregadas em suas demonstrações. Por fim, levando em consideração os dois primeiros livros da sua Ética, pretendo esclarecer em que medida o conceito de “vontade” tornou possível tanto a demonstração do conhecimento quanto da liberdade.

Conventional quantitative methods for the measurement of organizational legitimacy consider mainly three sources that make judgments about organizations visible: news media, accreditation bodies, and surveys. Over the last decade, however, social media have enabled ordinary citizens to bypass the gatekeeping function of these institutional evaluators and autonomously make individual judgments public. This inclusion of voices beyond functional and formally organized stakeholder groups potentially pluralizes the ongoing discussions about organizations. The individual judgments in blogs, tweets, and Facebook posts give indication about (...) the broader fit between an organization’s perceived behavior and heterogeneous social norms and therefore constitute an indicator of organizational legitimacy that can be accessed and measured. We propose the use of social media data and sentiment analysis to study the affect-based responses to organizational actions by citizens. We critically discuss and compare the method with existing quantitative methods for legitimacy measurement and apply them to a recent case in the banking industry. We discuss the value of the method for studying the process of legitimacy construction as the expression and negotiation of normative judgments about organizations by various evaluators. (shrink)

The paper aims at outlining some essential Neoplatonic traits in order to accomplish an ecological Metaphysics, by developing a dynamic and intensive notion of «Selfness» within three main fields of knowledge: Biology, Psychology, Cosmology. Starting from post-cybernetics systems’ theories, by deepening Bateson’s Ecology of Mind, in the end the research will restore the ancient One-Many aporia, showing its irrefutable value.
