Research on elders’ acceptance of virtual technologies is much needed. Here we studied the user experience of elders (N = 10, mean age = 88.2 years) during virtual biking, an exergame where participants pedal on a cycle ergometer and wear a Head-Mounted Display that provides them an immersive experience of a bike ride. We tested the effects of augmented gaze on user experience. Augmented gaze is a condition in which horizontal head turns yield amplified visual shifts, which is assumed to (...) facilitate visual exploration. User experience was measured by asking participants to rate satisfaction, motivation, sense of presence and sense of safety. We found a very good acceptance of virtual biking and no signs of negative effects of augmented gaze. These preliminary observations suggest that augmented gaze may be a viable optimization of elders’ experience with certain virtual reality applications. (shrink)

This paper investigates the semantics of the focus particle only and is primarily concerned with the relation between the exclusive proposition and the proposition expressed by the prejacent. We argue that, in a sentence of the form only A is B, only triggers the conditional presupposition that if something is B, A is B. We show that in a positive- only sentence, the prejacent is a conversational implicature and therefore it is cancellable. Instead, in a negative- only sentence the prejacent (...) is shown to be entailed by any context that satisfies the conditional presupposition and to which the assertion is added. Hence, the prejacent of a negative- only sentence is not cancellable. The entailment analyses, the strong presupposition analyses and the weak presupposition analyses of only are discussed, together with the problems that each type of theories faces. (shrink)

Opera logica.--De doctrinae ordine apologia.

In this paper, I give an analysis of neg-raising inferences as scalar implicatures. The main motivation for this account as opposed to a presupposition-based approach like Gajewski (Linguist Philos 30(3):289–328, 2007) comes from the differences between presuppositions and neg-raising inferences. In response to this issue, Gajewski (2007) argues that neg-raising predicates are soft presuppositional triggers and adopts the account of how their presuppositions arise by Abusch (J Semantics 27(1):1–44, 2010). However, I argue that there is a difference between soft triggers (...) and neg-raising predicates in their behavior in embeddings; a difference that is straightforwardly accounted for in the present approach. Furthermore, by adopting Abusch’s (2010) account of soft triggers, Gajewski (2007) inherits the assumptions of a pragmatic principle of disjunctive closure and of a non-standard interaction between semantics and pragmatics—assumptions that are not needed by the present proposal, which is just based on a regular theory of scalar implicatures. I also show that the arguments that Gajewski (2007) presents in favor of the presuppositional account can be explained also by the scalar implicatures-based approach proposed here. Finally, while the main point of the paper is a comparison with the presuppositional account, I sketch a preliminary comparison with more syntactic approaches to neg-raising. (shrink)

While the debate on values in science focuses on normative questions on the level of the individual (e.g. should researchers try to make their work as value free as possible?), comparatively little attention has been paid to the institutional and professional norms that researchers are expected to follow. To address this knowledge gap, we conduct a content analysis of leading national codes of conduct for research integrity of European countries, and structure our analysis around the question: do these documents allow (...) for researchers to be influenced by “non-epistemic” (moral, cultural, commercial, political, etc.) values or do they prohibit such influence in compliance with the value-free ideal (VFI) of science? Our results return a complex picture. On the one hand, codes of conduct consider many non-epistemic values to be a legitimate influence on the decision-making of researchers. On the other, most of these documents include what we call _VFI-like positions_: passages claiming that researchers should be free and independent from any external influence. This shows that while many research integrity documents do not fully endorse the VFI, they do not reject it and continue to be implicitly influenced by it. This results in internal tensions and underdetermined guidance on non-epistemic values that may limit some of the uses of research integrity codes, especially for purposes of ethical self-regulation. While codes of conduct cannot be expected to decide how researchers should act in every instance, we do suggest that they acknowledge the challenges of how to integrate non-epistemic values in research in a more explicit fashion.

Los orígenes de la APS y de la Política de SALUD PARA TODOS se remontan al siglo XVIII y al movimiento de Medicina Social de 1848. Del siglo XX se destacan las experiencias pioneras de los años 30-50s. Entre ellas, Chile, Saskachewa (Canadá), EUA, Suráfrica, con Henry Sigerist, Sidney Kark, Salvador Allende, Gustavo Molina, trabajos pioneros de la medicina y la epidemiologia social vinculados a los del antropólogo Benjamin Paul. Así como personajes menos reconocidos en APS especialmente el italiano Franco (...) Basaglia transformador de la atención psiquiátrica y sanitaria con los principios de libertad terapéutica. A éstas están articuladas numerosas y desconocidas experiencias en América Latina y Colombia con Héctor Abad Gómez, Santiago Rengifo y César Uribe Piedrahita por el proceso de “Renovación de APS” de la OPS. En Latinoamérica, las luchas por la salud estaban articuladas a la luchas por una sociedad justa, con personajes como Ernesto Guevara desde la medicina, Paulo Freire en pedagogía, teología y filosofía de la liberación, y el sociólogo colombiano Camilo Torres, que aportaron metodologías cualitativas en la investigación en salud, los que junto aportes de integración como el Desarrollo a Escala Humana, consideran a los servicios sanitarios como elementos principales en la vida de las personas, y aportan a la construcción transdisciplinar e intersectorial de la salud para nuestro hoy.

In the last few years, a remarkable convergence of interests and results has emerged between scholars interested in the arts and aesthetics from a variety of perspectives and cognitive scientists studying the mind and brain within the predictive processing (PP) framework. This convergence has so far proven fruitful for both sides: while PP is increasingly adopted as a framework for understanding aesthetic phenomena, the arts and aesthetics, examined under the lens of PP, are starting to be seen as important windows (...) into our mental functioning. The result is a vast and fast-growing research programme that promises to deliver important insights into our aesthetic encounters as well as a wide range of psychological phenomena of general interest. Here, we present this developing research programme, describing its grounds and highlighting its prospects. We start by clarifying how the study of the arts and aesthetics encounters the PP picture of mental functioning (§1). We then go on to outline the prospects of this encounter for the fields involved: philosophy and history of art (§2), psychology of aesthetics and neuroaesthetics (§3) and psychology and neuroscience more generally (§4). The upshot is an ambitious but well-defined framework within which aesthetics and cognitive science can partner up to illuminate crucial aspects of the human mind. -/- This article is part of the theme issue ‘Art, aesthetics and predictive processing: theoretical and empirical perspectives’. -/- .

Institutions represent a solid basis to organize and stabilize human life in diferent social contexts. They are external events in the world, but they also have a strong anchorage in the mind and in last years many scholars tried to explore their cognitive ground. Starting from the original attempt of Douglass C. North, who at the end of his career tried to establish a program called “Cognitive Institutionalism”, we discuss the merits and the limits of this approach. First, we show (...) that his statements are cognitively onerous as they imply the notions of mental models and beliefs. Instead, we argue that shared institutions do not require such a convergence and that coordination takes place in the form of social practices and habits. Second, we clarify some aspects of North’s cognitive theory avoiding the ontological reading, i.e. explaining in what sense institutions might depend on the human mind and how people are joined into a practice made possible via institutions.

We propose to develop the problems of selfness, of the tension between the other and the same, and of the singularity, by questioning the philosophies of Kant, Levinas and Stirner, and by reading them trough the theoretical eyes of Jacques Derrida. We will reflect on the irreducibility of the Levinasian other, trying to find out how, to what extent and with what difficulties, the emphasis on singularity can open a dialogical field between, on the one hand, the demand for ethical (...) transcendence required by the encounter with the other, and, on the other hand, the unconditional nature of the moral law in Kantian practical philosophy. After having underlined the limits of the latter, we will compare the non-conceptual and un-graspable character of the other with the radical Stirnerian uniqueness and his need to open the way to what escapes any logocentric chain. The relation between language, singularity and encounter will follow a resumption of Levinasian alterity under a more critical perspective. (shrink)

This work investigates one of the most widespread yet elusive ideas about our experience of art: the idea that there is something cognitively valuable in engaging with great artworks, or, in other words, that we learn from them. This claim and the age-old controversy that surrounds it are reconsidered in light of the psychological and neuroscientific literature on learning, in one of the first systematic efforts to bridge the gap between philosophical and scientific inquiries on the topic. The work has (...) five chapters. Chapter 1 lays down its conceptual bases: it explains what learning is taken to be in the current philosophical debate and it points out how Bayesian cognitive science (particularly in its predictive processing formulations) might be well-suited to capture the kind of learning involved in our engagement with the arts. The following chapters test this latter hypothesis with respect to particular art forms, namely literature and literary language (Chapter 2), narrative (Chapter 3), and visual art, music and motor activities (Chapter 4). The fine-grained discussions conducted in each of these areas will enable us to see that the relationship between art and learning is indeed fundamental and pervasive. The final chapter (Chapter 5) examines the consequences of this fact for our understanding of the role of art in our epistemic practices, its ultimate usefulness and value, and its place in the interdisciplinary study of the human mind. The upshot is a novel and wide-ranging picture, both philosophically informed and empirically sound, that bypasses many of the problems and dead ends of the current philosophical debate on the topic and captures the deep sense in which art and learning are interrelated.

Les positions philosophiques d'Anthony Collins étaient audacieuses et novatrices, de son rejet de l'idée d'un Dieu doué d'intelligence et de volonté à celui de l'existence d'une âme immatérielle, en passant par sa conception déterministe de la nature et sa vision de l'homme comme machine proche de l'animal, et mue par des pulsions tout aussi hédonistes.

In the present paper we use the theory of exact completions to study categorical properties of small setoids in Martin-Löf type theory and, more generally, of models of the Constructive Elementary Theory of the Category of Sets, in terms of properties of their subcategories of choice objects. Because of these intended applications, we deal with categories that lack equalisers and just have weak ones, but whose objects can be regarded as collections of global elements. In this context, we study the (...) internal logic of the categories involved, and employ this analysis to give a sufficient condition for the local cartesian closure of an exact completion. Finally, we apply this result to show when an exact completion produces a model of CETCS. (shrink)

In this article, I propose a semantic account of temporally mismatched past subjunctive counterfactuals. The proposal consists of the following parts. First, I show that in cases of temporal mismatch, [past] cannot be interpreted inside the proposition where it occurs at surface structure. Instead, it must be interpreted as constraining the time argument of the accessibility relation. This has the effect of shifting the time of the evaluation of the conditional to some contextually salient past time. Second, I will propose (...) specific felicity conditions (presuppositions) for subjunctive conditionals and I will argue that there is a strict correspondence between the time of evaluation in the truth conditions of a conditional and the time relevant for the felicity conditions. In other words, if the time relevant for the accessibility relation has been shifted to the past, then the conditional's presupposition will make reference to a past context. On the other hand, if no past is constraining the time argument of the accessibility relation, the conditional's felicity will make reference to the current (main) context. Third, I will argue that the intuition that the antecedent of mismatched counterfactuals is not true is a scalar implicature arising from a competition not between assertions but between presuppositions. Finally, I will investigate the repercussions of my proposal for the general theory of modality. (shrink)

Even if the “value-free ideal of science” (VFI) were an unattainable goal, one could ask: can it be a useful fiction, one that is beneficial for the research community and society? This question is particularly crucial for scholars and institutions concerned with research integrity (RI), as one cannot offer normative guidance to researchers without making some assumptions about what ideal scientific research looks like. Despite the insofar little interaction between scholars studying RI and those working on values in science, the (...) overlap of topics and interests make collaboration between the two fields promising for understanding research and its ethics. Here, we identify—for the use of RI scholars—the non-epistemic reasons (societal, political, professional) for and against the VFI considered in the literature. All of these are concerned with the beneficial or detrimental consequences that endorsing the VFI would have on society, policy-making, or the scientific community, with some authors appealing to the same principles to argue for opposite positions. Though most of the reviewed articles do not endorse the VFI, it is generally agreed that some constraints have to be put on the use of non-epistemic values. Disagreement on the utility of the VFI lies both on the different epistemic-descriptive positions taken by different authors, and on the scarcity of relevant empirical studies. Engaging critically with the reasons here identified and more in general with the values in science debate will help the RI community decide whether the VFI should be included in future codes of conduct.

Bermúdez identifies the “Interface Problem” as the central problem in the philosophy of psychology: how commonsensical psychological explanations can be integrated with lower-level explanations? In particular, since folk psychology is meant to provide causal explanations on a par with, say, neurobiological explanations, the question of how to understand the relation between the two layers arises naturally. Donald Davidson claimed that the interface problem is actually ill-posed and put forward his version of the “Autonomy Picture”, the view known as anomalous monism. (...) This work reviews Davidson’s proposal in the light of digital universes: we model the key claims of the theory using cellular automata and show that Davidson’s original version of the Autonomy Picture is immune to two arguments against autonomy.

In this paper, we study the distribution and interpretation of a non-temporal use of the future tense in Italian, called ‘presumptive’ or ‘epistemic’, which we label here PF. We first distinguish PF from its closest modal relatives, namely epistemic necessity/possibility/likelihood modals, as well as weak necessity modals. We then propose an account of PF in declaratives and interrogatives that treats it as a special comparative subjective likelihood modal, and test its empirical predictions. A theoretical lesson drawn from this detailed study (...) of the semantics of PF is that semantics needs sharpened theoretical tools to be able to capture the fine-grained distinctions languages make when it comes to signaling modulated epistemic commitment to a proposition.

In this paper I provide a unified analysis of a number of pragmatic anomalies that have been discussed in the literature. The paper’s main goal is to account for Sobel sequences of conditionals and sequences of disjunctive sentences, but I will also propose that this analysis can be extended to sequences of sentences with superlatives. The starting point is the observation that, while all these sequences are felicitous in one order, they are infelicitous when the order is reversed. Previous proposals (...) have focussed on particular types of infelicitous sequences Ken Hale: A life in language, MIT Press, Cambridge, 2001; Moss in Noûs 46:516–586, 2012; Lewis in Noûs 52:481–507, 2018; a.o.), or a subset of all the phenomena cited above Linguistic and psycholinguistic approaches on implicatures and presuppositions. Palgrave McMillan, Basingstoke, 2017; a.o.). I propose that sequences of sentences belonging to the same structured set of alternatives T are subject to a Specificity Constraint : sequences are acceptable if both alternatives are dominated by the same number of nodes in the structured set of alternatives T. Violations of SC can be avoided by strengthening the weaker alternative. However, covert strengthening violates an economy condition if the overtly stronger alternative is among those made salient by the preceding utterance in the sequence. I propose that the set of alternatives made salient by an utterance of a sentence s consists of s’s sisters and mother in T. I will show that the strengthening mechanism varies depending on the kind of sequence we have. (shrink)

The goal of this paper is to offer a compositional semantics for subjunctive and indicative will conditionals, and to derive the projection properties of the types of conditionals we consider and in particular those of counterfactual conditionals. It is argued that subjunctive conditionals are "bare" conditional embedded under temporal and aspectural operators, which constrain the interpretation of the modal operators in the embedded conditional. Furthermore, it is argued that a theory of presupposition projection à la Heim together with the present (...) proposal about their logical form explains the projection facts. (shrink)

In this paper, I argue that the aspectual, marginality, and concessive uses of the grading particles still and already can be reduced to the fol lowing three classes of focus sensitive-grading particles: additive particles like too, scalar particles like even, and exclusive particles like only. The meaning differences among the occurrences of still (and already) are mostly reduced to the differences among these three classes of grading particles. In turn, these differences are shown to correlate with what type of object (...) is denoted by the phrase in the scope of the particle. The proposal has repercussions also for the focus-sensitive particle again. I investigate the latter too, and I propose a parallel between the temporal and nominal domains where the contrast between still and again is analyzed along the lines of the contrast between definite and indefinite noun phrases.

I subsequently proceed to explore the conceptualisation of health according to the Marxist scientists Richard Levins and Richard Lewontin through the model of dialectical biology.

Cellular automata (henceforth: CA) are discrete, abstract computational systems that have proved useful both as general models of complexity and as more specific representations of non-linear dynamics in a variety of scientific fields. Firstly, CA are (typically) spatially and temporally discrete: they are composed of a finite or denumerable set of homogeneous, simple units, the atoms or cells. At each time unit, the cells instantiate one of a finite set of states. They evolve in parallel at discrete time steps, following (...) state update functions or dynamical transition rules: the update of a cell state obtains by taking into account the states of cells in its local neighborhood (there are, therefore, no actions at a distance). Secondly, CA are abstract, as they can be specified in purely mathematical terms and implemented in physical structures. Thirdly, CA are computational systems: they can compute functions and solve algorithmic problems. Despite functioning in a different way from traditional, Turing machine-like devices, CA with suitable rules can emulate a universal Turing machine, and therefore compute, given Turing's Thesis, anything computable....

This article discusses the connection between Western socialist parties and technological development during the 1950s. The cases of the British Labour Party (LP), the German Social Democracy (SPD), and the Italian Socialist Party (PSI) let us to examine socialist perspectives in managing technological progress and in conceiving programmes and purposes on scientific research. This choice allows to understand two different aspects: on the one hand, the new pragmatism of socialist and social democratic parties, which was a typical trait of Postwar's (...) socialist revisionism; on the other hand, the predominance assumed by domestic affairs in socialists’ vision, instead international topics. A very specific choice concerns the article's main focus. A large historiographical dispute has started to trace about Postwar Social Democracy's revisionism. Given such historiographical debate, this article firstly explores the behaviour and politics of the LP, the SPD, and the PSI about the the so-called modernization, a process which concerned the entire Postwar Europe. It also discusses programmes or ideas circulations about the 1950s ‘technological revolution’ and the agendas settled by socialist and social democratic parties to govern such global phenomena.

Le evidenze strutturali oggi conservate sono state integrate nella scena 3D con puntuali confronti coevi (III sec. d.C.), virtualmente ricostruiti e ricollocati in contesti d’uso verosimili, accrescendo così l’affidabilità ricostruttiva. L’intera attività ricostruttiva è stata vincolata a un rigoroso processo di validazione scientifica basato sul metodo dell’Extended matrix e l’esito finale è ora fruibile sia mediante proiezioni tradizionali (off-site, tourismA 2020), sia mediante l’utilizzo di dispositivi mobili VR (on-site, Giornate europee del patrimonio 2020). In queste e altre occasioni si è riscontrata una eccellente risposta del pubblico, agevolato dal virtuale nella percezione e nella comprensione delle evidenze e delle volumetrie antiche. (shrink)
