BackgroundA child’s death is the most stressful event and the most complex grief that families face. The process of psychological adaptation to the illness and death of a child is difficult due to a variety of emotional reactions. Parental grief had received the attention of researchers only in recent years when it became clear that this reality differs substantially from the general grief process.ObjectiveThis work aims to highlight the needs of bereaved parents; increase the specificity and effectiveness of the therapeutic (...) approach to prevent complications in the process of loss-making; and find the recurrent thematic nuclei in the development of bereavement present in a therapeutic group of parents who have lost their child to an onco-hematological disease.MethodBetween 2011 and 2016, five therapeutic groups for the grief elaboration were made. The sample included a total of 50 parents of children who died from cancer between the ages of 0 and 21 years.Content analysis was carried out as a qualitative analysis method. The SAS® Text Miner software was used to read, interpret, classify and integrate the data from numerous sources.ResultsThe development and consecutive interpretation of the 5 clusters have been carried out to analyze the related topics using the node “Topic Analysis” and requesting the subdivision into five topics. Four topics have been well defined. Clear topics are reducible to categories of emotional relief, tools, legacy, and unfinished business. The topic analysis provides interesting indications about the different interpretive journeys of the bereavement situation and offers ideas regarding the different types of social responses.ConclusionsAfter reviewing the existing bibliography, we have confirmed the lack of specific literature on the problem of grief in parents whose children have died from cancer. Much research has shown that parents who lose a child to cancer want support, and there are still few studies on the most effective interventions for this group. (shrink)

The idea of an ?inversion principle?, and the name itself, originated in the work of Paul Lorenzen in the 1950s, as a method to generate new admissible rules within a certain syntactic context. Some fifteen years later, the idea was taken up by Dag Prawitz to devise a strategy of normalization for natural deduction calculi (this being an analogue of Gentzen's cut-elimination theorem for sequent calculi). Later, Prawitz used the inversion principle again, attributing it with a semantic role. Still working (...) in natural deduction calculi, he formulated a general type of schematic introduction rules to be matched ? thanks to the idea supporting the inversion principle ? by a corresponding general schematic Elimination rule. This was an attempt to provide a solution to the problem suggested by the often quoted note of Gentzen. According to Gentzen ?it should be possible to display the elimination rules as unique functions of the corresponding introduction rules on the basis of certain requirements?. Many people have since worked on this topic, which can be appropriately seen as the birthplace of what are now referred to as ?general elimination rules?, recently studied thoroughly by Sara Negri and Jan von Plato. In this study, we retrace the main threads of this chapter of proof-theoretical investigation, using Lorenzen's original framework as a general guide. (shrink)

This paper is a study of the opening section of Gentzen’s first publication of 1932,Über die Existenz unabhängiger Axiomensysteme zu unendlichen Satzsystemen, a text which shows the relevance of Hertz’s work of the 1920’s for the young Gentzen. In fact, Gentzen borrowed from Hertz the analysis of the notion of consequence, which was given in terms of the rules of thinning (Verdünnung) and cut (Schnitt) on sequents (there called “sentences”(Sätze)). Moreover, following Hertz again, he also judged it necessary to justify (...) the forms of inference of the system by providing a semantics for them, so that it became possible to make precise the informal notion of consequence, and to show that the inference rules adopted are correct and sufficient.

The paper is devoted to an examination of the epistemic account of the notion of deductive inference recently provided by D. Prawitz, and based on the notion of ground. This is part of the general scenario constituted by the “Proof-theoretic semantics”, presented since the ’70s of the last century as an alternative to the standard model-theoretic explication of the notion of logical consequence.Our argument pivots on the so-called “Curry–Howard Correspondence”, which exploited the idea of considering proofs as proper mathematical objects (...) in a remarkable way. A sort of rational reconstruction of this idea is outlined, tracing it back to Hilbert and Husserl’s investigations. (shrink)

A partire dagli anni '60, György Lukács intraprende una ricerca volta a recuperare e sviluppare l'ontologia sociale racchiusa negli scritti di Marx nel tentativo di rinnovare la riflessione marxista dopo l'effetto inibitorio provocato dallo Stalinismo. Lo scopo di questo articolo è di indagare la concezione lukácsiana dell'ideologia come funzione sociale, mettendola in relazione con il regime di complessità descritto da Lukács nella sua ultima opera, Ontologia dell'essere sociale. Recuperando il riferimento goethiano implicito nell'idea di lavoro come “fenomeno originario” dell'azione sociale, (...) tenteremo di riconcettualizzare la teoria del rispecchiamento adottata nell'Ontologia al fine di mostrare il ruolo che viene ad assumere l'ideologia all'interno di una società volta alla produzione del futuro.

The focus of this paper is on two attempts Sainati made to renew neo-idealistic themes by means of suggestions drawn from the famous Goedel’s Incompleteness Theorems of 1931. Sainati’s remarks on the relationship between «logo astratto » and «logo concreto» are here pursued by reference to some of Goedel’s unpublished texts.

This article reflects on the relationships between hegemonic masculinity, technologies and masturbation. It is established that this sexual practice has been determined by a series of powers and "myth loops" that, especially affecting cis-hetero men, have limited the emancipatory possibilities of self-pleasure. The text provides a general historical overview to review relevant gender differences regarding to masturbation, and focuses specifically on the Chilean case, their traditions, norms, evaluations and stereotypes to review the emergence of hegemonic male masturbatory practices. These and (...) their performativities will reveal a series of incongruities that take the body back to mandates associated with a control paradigm, which hinder an optimal development of both autoerotics and shared sexuality.

A key question in the theory of migration and in public debates on immigration policies is when migration can be said to be voluntary and when, conversely, it should be seen as nonvoluntary. In a previous article, we tried to answer this crucial question by providing a list of conditions we view as sufficient for migration to be considered nonvoluntary. According to our account, one condition that makes migration nonvoluntary is when people migrate because they lack acceptable alternatives to doing (...) so. In this article, we take the opportunity to further explore and clarify this crucial condition. More specifically, we focus on two main sets of questions. First, we ask whether migration is always voluntary when it serves goals that are voluntarily chosen, and whether those who decide to migrate voluntarily but only have the option of choosing among a limited set of dangerous, harmful, or illegal means for doing so, can be said to be forced to choose those means. Second, we ask whether what counts as “nonacceptable” alternatives should also include cases in which people could have their needs and fundamental rights met, but at the cost of betraying their moral principles or conceptions of the good.

In Aristotle and Menander on the Ethics of Understanding , Valeria Cinaglia offers a parallel study of Menander’s New Comedy and Aristotle’s philosophy and she explores the depth and implications of their analogies in subjects ranging from epistemology and psychology to ethics.

O advento da sociedade em rede promoveu mudanças significativas na experiência-com-o-mundo. Observa-se nos últimos anos a crescente toxidade no ambiente informacional, marcado tanto pela vivência tóxica da informação que circula legalmente nas redes sociais como por informações que intoxicam os indivíduos e grupos. O objetivo é discutir, em tempos de pós-verdade e da sociedade non-stop, o aspecto tóxico da informação, que ao tornar o ambiente informacional tóxico, adoece indivíduos e também as sociedades democráticas, ao esmaecer a empatia para com os (...) demais e de pôr em risco a própria ideia de democracia e de vida partilhada de modo democrático. A proposta é discutir a intoxicação pela informação não pelo excesso (infoxicação), mas pelo que nomeio informação tóxica, i.e., o aspecto tóxico da informação e de ambiente informacional tóxico tendo como referência os discursos de ódio. Para tanto serão consideradas a desconstrução de experiências de estados democráticos mediante o crescimento da circulação de discursos de ódio e de discursos de ódio fascistas; o crescimento da desinformação; o crescimento da circulação de notícias fraudulentas (Fake news) e de notícias falsas (por exemplo, as não endossadas pelos saberes científicos, como o terraplanismo, a ideia da supremacia branca); os robots e os algoritmos.

In the first part of the paper, previous work about embodied mathematics and the practice of topology will be presented. According to the proposed view, in order to become experts, topologists have to learn how to use manipulative imagination: representations are cognitive tools whose functioning depends from pre-existing cognitive abilities and from specific training. In the second part of the paper, the notion of imagination as “make-believe” is discussed to give an account of cognitive tools in mathematics as props; to (...) better specify the claim, the notion of “affordance” is explored in its possible extension from concrete objects to representations.

In their everyday work, scholars constantly acquire and transfer knowledge. Many of these knowledge flows are difficult to observe, not least because scholars are often not aware of them. This may be the reason why the attention to knowledge flows is very unevenly distributed across science studies, with bibliometric citation-based studies contributing the most research. Starting from the premise that bibliometric methods can be more readily exploited in the study of knowledge flows, this review explores the potential of bibliometric methods (...) for the investigation of knowledge flows. Bibliometrics provides a portfolio of data and methods that can be used alone or in combination with qualitative methods to study knowledge flows. We organise contributions to the study of knowledge flows according to their object of study—formal, informal, or tacit knowledge—and according to the mode of flow—impersonal or interpersonal knowledge flow. The review shows that bibliometrics is strongly focused on the use of citation data for the investigation of impersonal flows of formal knowledge and has recently turned to the impersonal flow of informal knowledge via social media. In contrast, there are only few bibliometric studies that address interpersonal flows of knowledge. The review identifies an under-utilised potential of bibliometric methods and suggests some directions for future methodological development. (shrink)

Demographic growth has in recent years been one of the determining characteristics of African development, and if projections are correct, the continent is set to become a population superpower. Its proportion of the world population, especially relative to the “old continent”, is increasing in a historically unprecedented manner, and its inhabitants are younger than ever. Although it is still difficult to assess whether this trend should be regarded as an opportunity or as a potential risk factor, it is already possible (...) to discern the first definitive signs of how this evolving new distribution of demographic power is shifting Africa’s geopolitical and economic position in today’s polycentric world.

Pour déterminer la cognoscibilité du Premier principe, Avicenne emprunte dans sa Métaphysique trois voies: la connaissance scientifique par démonstration, l’intuition intellective et la connaissance à travers le discours prophétique. Dans le cadre de la réception de l’Éthique aristotélicienne, les maîtres ès arts de Paris empruntent deux de ces voies au milieu du XIIIe siècle. Même si beaucoup d’éléments sont semblables dans les deux cas, les artiens ne sortiront pas de leur spécificité professionnelle: le discours philosophique.

Elegeu-se o método dedutivo, a técnica bibliográfica. Conclui-se que o exercício da democracia pela cidadania (...) nos observatórios sociais, sob o princípio da sustentabilidade, faz valer a vontade popular na tomada de decisões. (shrink)

Italian philosopher Giorgio Agamben presents an account of the political upheavals that ensued as the COVID-19 pandemic brought his country—and with it his countrymen's personal liberties—to a crashing halt. While controversial, Agamben’s reflections on the transformation of Western democracies hold implications far beyond any present crisis.

Although there is much confusion about it in everyday language, the distinction between public and common goods is clear enough within Economics. While the former involves the fact of being open to all and state management, the latter requires common but still limited management. The different kind of administration can also be explored through the reference to a different kind of agent meant as the one who makes use of the different goods: if in the case of public goods, we (...) have individuals, as an aggregate, in that of commons we necessarily need to assume the existence of a plural form of subject, who can in fact act in concert in the management of the good itself. Exploring this distinction in its details and consequences, the paper sets out to apply it to a typical public good – green areas in cities – and to show the theoretical advantages that such a consideration of the commons can have, including through a concrete case such as community gardens.

The theory that ``consistency implies existence'' was put forward by Hilbert on various occasions around the start of the last century, and it was strongly and explicitly emphasized in his correspondence with Frege. Since (Gödel's) completeness theorem, abstractly speaking, forms the basis of this theory, it has become common practice to assume that Hilbert took for granted the semantic completeness of second order logic. In this paper I maintain that this widely held view is untrue to the facts, and that (...) the clue to explain what Hilbert meant by linking together consistency and existence is to be found in the role played by the completeness axiom within both geometrical and arithmetical axiom systems.

The aim of this paper is to reconsider several proposals that have been put forward in order to develop a Proof-Theoretical Semantics, from the by now classical neo-verificationist approach provided by D. Prawitz and M. Dummett in the Seventies, to an alternative, more recent approach mainly due to the work of P. Schroeder-Heister and L. Hallnäs, based on clausal definitions. Some other intermediate proposals are very briefly sketched. Particular attention will be given to the role played by the so-called Fundamental (...) Assumption. We claim that whereas, in the neo-verificationist proposal, the condition expressed by that Assumption is necessary to ensure the completeness of the justification procedure ( from the outside , so to speak), within the definitional framework it is a built-in feature of the proposal. The latter approach, therefore, appears as an alternative solution to the problem which prompted the neo-verificationists to introduce the Fundamental Assumption. (shrink)

The link between force, violence and events in the philosophy of Jacques Derrida is explored, arguing that this relationship is at the very heart of the problem of meaning and its performativity. This thesis is based on the analysis of Derrida’s reading of both Benjamin’s Critique of Violence, as well as Austin’s linguistic performative theory, which allows, at first, to link the question of signification with that of force or violence. Subsequently, we use the analysis of W. Hamacher about Benjamin (...) in order to strengthen that connection and propose a new reading of the question of the event in Derrida. We obtain a philosophy of the event that moves between ethics, politics and linguistics that allows new approaches to the “critique” of violence. (shrink)

Authentic human life is the open-ended dialogue. Life by its very nature is dialogic. To live means to participate in dialogue: to ask questions, to head, to respond, to agree, and so forth. In this dialogue a person participates wholly and throughout his whole life: with his eyes, lips, hands, soul, spirit, with his whole body and deeds. He invests his entire self in discourse, and this discourse enters into the dialogic fabric of human life, into the world symposium. (Bahktin, (...) 1984, p. 283)... (shrink)

Equal respect for persons is often appealed to as the grounding principle of democratic rule. I argue here that if it needs to account for the specific content of democratic political rights, it must be understood as respect for people as competent political decision-makers. However, the claim that respect is due to people as a response to their actual equal competence leads to a conflation of democratic legitimacy and substantive justice, resting on implausible factual assumptions and making it impossible to (...) advocate the effective equalization of political capabilities. Therefore, I suggest that the principle of equal respect should be decoupled from such a claim and be rephrased as simply prescribing that people be treated or publicly recognized as equally competent. I defend this interpretation against the publicity objection, according to which this take on the principle implies insincerity and therefore cannot serve as a public justification for democratic authority.

Guided by a phenomenological perspective, this paper aims to account for the existence of a corporeal consciousness—something that clinicians should take into account, not merely in the case of physical pathologies but especially in the case of mental disorders. Firstly, I will highlight three cases: schizophrenia, depression, and autism spectrum disorder. Then, I will show how these cases correspond to three different kinds of bodily existence: disembodiment (in the case of schizophrenia), chrematization (in melancholic depression), and dyssynchrony (in the autism (...) spectrum disorder). Finally, I will argue for the importance of an “expressive common environment” between the patient and the clinician, who are two distinct, embodied conscious subjects resonating with one another. In this view, the primary goal of the therapeutic process seems to develop a shared understanding of the patient’s life-world, which finds its main expression through the disrupted body. (shrink)

This introduction aims to familiarize readers with basic dimensions of variation among pictorial and diagrammatic representations, as we understand them, in order to serve as a backdrop to the articles in this volume. Instead of trying to canvas the vast range of representational kinds, we focus on a few important axes of difference, and a small handful of illustrative examples. We begin in Section 1 with background: the distinction between pictures and diagrams, the concept of systems of representation, and that (...) of the properties of usage associated with signs. In Section 2 we illustrate these ideas with a case study of diagrammatic representation: the evolution from Euler diagrams to Venn diagrams. Section 3 is correspondingly devoted to pictorial representation, illustrated by the comparison between parallel and linear perspective drawing. We conclude with open questions, and then briefly summarize the articles to follow. (shrink)
