We give the precise correspondence between polarized linear logic and polarized classical logic. The properties of focalization and reversion of linear proofs are at the heart of our analysis: we show that the tq-protocol of normalization for the classical systems and perfectly fits normalization of polarized proof-nets. Some more semantical considerations allow us to recover LC as a refinement of multiplicative.

This article refers to the idea of Constitution, understood as a social contract. It is argued that the emergence of new actors in the Latin American constituent processes has made it possible to appreciate the Constitutions as increasingly complex pacts. It is not only a pact “between individuals” or “between citizens”, but it can also be understood as an agreement between cultures, between human beings and nature, and even between men and women. It ends by noting that, as new groups (...) participate in the constituent processes, the pacts will also become increasingly diverse, so that the concept of Constitution continues to be a concept in construction.

The present report is a, somewhat lengthy, addendum to [4], where the elimination of cuts from derivations in sequent calculus for classical logic was studied 'from the point of view of linear logic'. To that purpose a formulation of classical logic was used, that - as in linear logic - distinguishes between multiplicative and additive versions of the binary connectives. The main novelty here is the observation that this type-distinction is not essential: we can allow classical sequent derivations to use (...) any combination of additive and multiplicative introduction rules for each of the connectives, and still have strong normalization and confluence of tq-reductions. We give a detailed description of the simulation of tq-reductions by means of reductions of the interpretation of any given classical proof as a proof net of PN2 (the system of second order proof nets for linear logic), in which moreover all connectives can be taken to be of one type, e.g., multiplicative. We finally observe that dynamically the different logical cuts, as determined by the four possible combinations of introduction rules, are independent: it is not possible to simulate them internally, i.e., by only one specific combination, and structural rules.

We propose Rhythmic Relating for autism: a system of supports for friends, therapists, parents, and educators; a system which aims to augment bidirectional communication and complement existing therapeutic approaches. We begin by summarizing the developmental significance of social timing and the social-motor-synchrony challenges observed in early autism. Meta-analyses conclude the early primacy of such challenges, yet cite the lack of focused therapies. We identify core relational parameters in support of social-motor-synchrony and systematize these using the communicative musicality constructs: pulse; quality; (...) and narrative. Rhythmic Relating aims to augment the clarity, contiguity, and pulse-beat of spontaneous behavior by recruiting rhythmic supports and relatable vitality; facilitating the predictive flow and just-ahead-in-time planning needed for good-enough social timing. From here, we describe possibilities for playful therapeutic interaction, small-step co-regulation, and layered sensorimotor integration. Lastly, we include several clinical case examples demonstrating the use of Rhythmic Relating within four different therapeutic approaches. These clinical case examples are introduced here and several more are included in the Supplementary Material. A suite of pilot intervention studies is proposed to assess the efficacy of combining Rhythmic Relating with different therapeutic approaches in playful work with individuals with autism. Further experimental hypotheses are outlined, designed to clarify the significance of certain key features of the Rhythmic Relating approach. (shrink)

Artefacts do not always do what they are supposed to, due to a variety of reasons, including manufacturing problems, poor maintenance, and normal wear-and-tear. Since software is an artefact, it should be subject to malfunctioning in the same sense in which other artefacts can malfunction. Yet, whether software is on a par with other artefacts when it comes to malfunctioning crucially depends on the abstraction used in the analysis. We distinguish between “negative” and “positive” notions of malfunction. A negative malfunction, (...) or dysfunction, occurs when an artefact token either does not or cannot do what it is supposed to. A positive malfunction, or misfunction, occurs when an artefact token may do what is supposed to but, at least occasionally, it also yields some unintended and undesirable effects. We argue that software, understood as type, may misfunction in some limited sense, but cannot dysfunction. Accordingly, one should distinguish software from other technical artefacts, in view of their design that makes dysfunction impossible for the former, while possible for the latter. (shrink)

Giuseppe Bronzini draws up the balance sheet of fifteen months of fully public work by the Convention that brought together the European countries for the drafting of a political constitution. Even though the debates have not clearly decided between an as-yet-to-be defined federalism able to give new impetus to the European social model and a functional, strongly liberal interstate cooperation, still we see all the signs of the decline of sovereignist positions, along with the subversive potential of some of (...) the constitutional texts.

Recently the complexity of discursive practices has been widely acknowledged by the humanities and social sciences. In fact, to know anything is to know in terms of one or more discourse. The "discursive turn" in psychology may be considered as a new paradigm oriented to a correct study of (wo)man only if it is able to grasp the semiotical ground of psychic experience both as an "effort after meaning" and as a "struggle over meaning." In this sense the notion of (...) "diatext" has been proposed as a contribution in working out a psychosemiotical approach to understand how the discursive practices assign subject-positions to the agents of each interlocution scenario.

This article reflects on a survey carried out at a non-profit organization that deals with health care for oncological terminally ill in order to find out for those who are involved in this project each worker's time projection and well-being class. The survey has pointed out each single team member's time perspective and well-being class and allowed building a pedagogical path for work orientation that has involved the same team members.

The recent in vitro derivation of gamete‐like cells from mouse embryonic stem (mES) cells is a major breakthrough and lays down several challenges, both for the further scientific investigation and for the bioethical and biolegal discourse. We refer here to these cells as gamete‐like (sperm‐like or oocyte‐like, respectively), because at present there is still no evidence that these cells behave fully like bona fide sperm or oocytes, lacking the fundamental proof, i.e. combination with a normally derived gamete of the opposite (...) sex to yield a normal individual. However, the results published so far do show that these cells share some defining features of gametes. We discuss these results in the light of the bioethical and legal questions that are likely to arise would the same process become possible with human embryonic stem (hES) cells. (shrink)

Giuseppe Gallis konsequentes Streben nach einer angemessenen Berücksichtigung beider Pole, des Subjektpols ebenso wie des Objektpols, sowohl in der Forschung als auch in allen Bereichen des menschlichen Lebens kommt im vorliegenden Sammelband in allen Arbeiten zum Tragen. Galli eröffnet damit auch neue Felder f8r die gestalttheoretische Forschungs- und Anwendungspraxis. Er erschließt Themen, die nicht zuletzt auch f8r die medizinischen, philosophischen, psychologischen und psychotherapeutischen Aufgabenstellungen zentral sind. Er plädiert nicht nur allgemein für einen dialogischen Ansatz in der zwischenmenschlichen Begegnung, er (...) führt in einer Reihe von Aufsätzen in diesem Sammelband auch sehr konkret die Fruchtbarkeit eines solchen Dialogs mit der Gedankenwelt eines Norbert Elias, Szvetan Todorovic und Paul Ricoeur für eine Bereicherung und Weiterentwicklung der Gestalttheorie vor Augen.

This book explores the significance of rhetoric from the perspective of its complex relationship with philosophy. It demonstrates how this relationship gives expression to a basic tension at the core of politics: that between the contingency of its happening and the transcendence toward which it strives. The first part of the study proposes a reassessment of the ancient quarrel between philosophy and rhetoric, as it was discussed by Plato, Aristotle, and above all Cicero and Quintilian, who ambitiously attempted to bring (...) them together creating an ideal that is at the roots of the humanist tradition. It then moves to twentieth-century political theory and shows how the questions that emerge from that quarrel still strongly resonate in the works of key thinkers such as H. Arendt, L. Strauss, and R. Rorty. The volume thus offers an original contribution that locates itself at the intersection of politics, rhetoric, and philosophy. (shrink)

In their 2002 seminal paper Hauser, Chomsky and Fitch hypothesize that recursion is the only human-specific and language-specific mechanism of the faculty of language. While debate focused primarily on the meaning of recursion in the hypothesis and on the human-specific and syntax-specific character of recursion, the present work focuses on the claim that recursion is language-specific. We argue that there are recursive structures in the domain of motor intentionality by way of extending John R. Searle’s analysis of intentional action. We (...) then discuss evidence from cognitive science and neuroscience supporting the claim that motor-intentional recursion is language-independent and suggest some explanatory hypotheses: linguistic recursion is embodied in sensory-motor processing; linguistic and motor-intentional recursions are distinct and mutually independent mechanisms. Finally, we propose some reflections about the epistemic status of HCF as presenting an empirically falsifiable hypothesis, and on the possibility of testing recursion in different cognitive domains.

We analyze selected iterated conditionals in the framework of conditional random quantities. We point out that it is instructive to examine Lewis's triviality result, which shows the conditions a conditional must satisfy for its probability to be the conditional probability. In our approach, however, we avoid triviality because the import-export principle is invalid. We then analyze an example of reasoning under partial knowledge where, given a conditional if A then Cas information, the probability of A should intuitively increase. We explain (...) this intuition by making some implicit background information explicit. We consider several (generalized) iterated conditionals, which allow us to formalize different kinds of latent information. We verify that for these iterated conditionals the prevision is greater than or equal to the probability of A. We also investigate the lower and upper bounds of the Affirmation of the Consequent inference. We conclude our study with some remarks on the supposed "independence" of two conditionals, and we interpret this property as uncorrelation between two random quantities. (C) 2020 Elsevier Inc.

We offer a formal treatment of the semantics of both complete and incomplete mistrustful or distrustful information transmissions. The semantics of such relations is analysed in view of rules that define the behaviour of a receiving agent. We justify this approach in view of human agent communications and secure system design. We further specify some properties of such relations.

This paper proposes an interpretation of Nāgārjuna’s doctrine of the two truths that considers saṃvṛti and paramārtha-satya two visions of reality on which the Buddhas, for soteriological and pedagogical reasons, build teachings of two types: respectively in agreement with (for example, the teaching of the Four Noble Truths) or in contrast to (for example, the teaching of emptiness) the category of svabhāva. The early sections of the article show to what extent the various current interpretations of the Nāgārjunian doctrine of (...) the dve satye—despite their sometimes even macroscopic differences—have a common tendency to consider the notion of śūnyatā as a teaching not based on, but equivalent to supreme truth. This equivalence—philologically questionable—leads to interpretative paths that prove inevitably aporetic: indeed, according to whether the interpretation of śūnyatā is ‘metaphysical’ or ‘anti-metaphysical’, it gives rise to readings of Nāgārjuna’s thought incompatible, respectively, with anti-metaphysical and realistic types of verses traceable in the works of the author of the Mūla-madhyamaka-kārikā (MMK). On the contrary, by giving more emphasis to the expression samupāśritya (“based on”), which recurs in MMK.24.8, and therefore, by epistemologically separating the notion of śūnyatā from the notion of paramārtha-satya (and of some of its conceptual equivalents such as nirvāṇa, tattva and dharmatā), we may obtain an interpretation—at once realistic and anti-metaphysical—of the theory of the two truths compatible with the vast majority (or even totality) of Nāgārjuna’s verses.

The process of completing, correcting and prioritising specifications is an essential but very complex task for the maintenance and improvement of software systems. The preservation of functionalities and the ability to accommodate changes are main objectives of the software development cycle to guarantee system reliability. Logical theories able to fully model such processes are still insufficient. In this paper we propose a full formalisation of such operations on software systems inspired by the Alchourrón–Gärdenfors–Makinson paradigm for belief revision of human epistemic (...) states. We represent specifications as finite sets of formulas equipped with a priority relation that models functional entrenchment of properties. We propose to handle specification incompleteness through ordered expansion, inconsistency through ordered safe contraction and prioritisation through revision with reordering, and model all three in an algorithmic fashion. We show how the system satisfies basic properties of the AGM paradigm, including Levi’s and Harper’s identities. We offer a concrete example and complexity results for the inference and model checking problems on revision. We conclude by describing resilience and evolvability of software systems based on such revision operators. (shrink)

One of the most fascinating topics of research within human sciences is the “Body-Mind Problem.” Since its beginning psychological research has focused on the notions of mind and consciousness adopting a purely naturalist perspective, which tends to explain them in terms of causal relationships and to reduce their intrinsic complexity. Conversely, the analysis of the discursive practices through which mind and consciousness reveal themselves through communication suggest the adoption of a psycho-semiotic approach, thus enhancing a “culturalist epistemology.” The aim of (...) the present article is to explore and to discuss the implications of such a theoretical and methodological option.

Coherent-ambiguity aversion is defined within the smooth-ambiguity model as the combination of choice-ambiguity and value-ambiguity aversion. Five ambiguous decision tasks are analyzed theoretically, where an individual faces two-stage lotteries with binomial, uniform, or unknown second-order probabilities. Theoretical predictions are then tested through a 10-task experiment. In tasks 1–5, risk aversion is elicited through both a portfolio choice method and a BDM mechanism. In tasks 6–10, choice-ambiguity aversion is elicited through the portfolio choice method, while value-ambiguity aversion comes about through the (...) BDM mechanism. The behavior of over 75 % of classified subjects is in line with the KMM model in all tasks 6–10, independent of their degree of risk aversion. Furthermore, the percentage of coherent-ambiguity-averse subjects is lower in the binomial than in the uniform and in the unknown treatments, with only the latter difference being significant. The most part of coherent-ambiguity-loving subjects show a high risk aversion. (shrink)

The purpose of this study is not so much to show the presence of Antisthenes in the dialogue, but rather to examine that to which Plato alludes. The controversy over ideas between the two Socratics is histori­cally very well-attested, as can already be seen in the Cratylus. Thus, it is reasonable to assume that this controversy must have affected Plato when he was writing the Phaedo: a dialogue in which the importance of ideas and his new logic is undeniable. Hence, (...) this paper will investigate the following question: what impact could Antisthenes’ denominative and definitory logic have on the equally denominative and definitory logic presented in the Phaedo, given that the latter work in all prob­ability preceded the Sathōn? In light of what is said in the dialogue, the answer focuses primarily on what would not be said. Thus, this study is divided into two parts: Part one shows how the so-called “second navigation” emerges as an objection to the insufficiency of the responses given by the physiologists. Tellingly, certain “common opinions” are regarded as perplexing and individuals holding them are referred to with the indeterminate tis, which – as is argued – must have included Antisthenes. Indeed, Tht. 108c7–8 reports the latter to have made common opinions a cornerstone of his denominative logic. Part two, on the other hand, is devoted to examining the so-called “final argument.” Here, Antisthenes’ presence seems somewhat more nuanced, given his incomplete knowledge of the new logic of irreversible opposites which was worked out by Plato for the purpose of demonstrating the immor­tality and indestructibility of the soul. On the other hand, Antisthenes is likely to have prompted Plato to specify the relationship between ideas and things in the definitory logic, since the proponent of the theory of oikeios logos refused to distinguish between the substance and its attrib­utes, the differences and their opposites, and the opposites of opposites.
