Background: The new human coronavirus that leads to COVID-19 has spread rapidly around the world and has a high degree of lethality. In more severe cases, patients remain hospitalized for several days under treatment of the health team. Thus, it is important to develop and use technologies with the aim to strengthen conventional therapy by encouraging movement, physical activity, and improving cardiorespiratory fitness for patients. In this sense, therapies for exposure to virtual reality are promising and have been shown to (...) be an adequate and equivalent alternative to conventional exercise programs.Aim: This is a study protocol with the aim of comparing the conventional physical therapy intervention with the use of a non-immersive VR software during COVID-19 hospitalization.Methods: Fifty patients hospitalized with confirmed diagnosis of COVID-19 will be divided in two groups under physiotherapy treatment using conventional or VR intervention: Group A: participants with COVID-19 will start the first day of the protocol with VR tasks in the morning and then in the second period, in the afternoon, will perform the conventional exercises and Group B: participants with COVID-19 will start the first day with conventional exercises in the morning and in the second period, in the afternoon, will perform activity with VR. All participants will be evaluated with different motor and physiologic scales before and after the treatment to measure improvements.Conclusion: Considering the importance of benefits from physical activity during hospitalization, VR software shows promise as a potential mechanism for improving physical activity. The results of this study may provide new insights into hospital rehabilitation.Trial Registration:ClinicalTrials.gov, identifier: NCT04537858. Registered on 01 September 2020. (shrink)

A Filosofia Renascentista muitas vezes é desprezada no estudo filosófico; no entanto, essa fase da história merece destaque em razão do surgimento do humanismo, movimento intelectual que enaltece a figura humana. A centralização do homem no mundo é tratada nas obras de Giovanni Pico della Mirandola e Blaise Pascal, filósofos em destaque nesta sucinta pesquisa.

This paper makes a plea for more reflexive attempts to develop and anchor the emerging concept of responsible research and innovation. RRI has recently emerged as a buzzword in science policy, becoming a focus of concerted experimentation in many academic circles. Its performative capacity means that it is able to mobilise resources and spaces despite no common understanding of what it is or should be ‘made of’. In order to support reflection and practice amongst those who are interested in and (...) using the concept, this paper unpacks understandings of RRI across a multi-disciplinary body of peer-reviewed literature. Our analysis focuses on three key dimensions of RRI that remain particularly opaque. A total of 48 publications were selected through a systematic literature search and their content was qualitatively analysed. Across the literature, RRI is portrayed as a concept that embeds numerous features of existing approaches to govern and assess emerging technologies. Our analysis suggests that its greatest potential may be in its ability to unify and provide political momentum to a wide range of long-articulated ethical and policy issues. At the same time, RRI’s dynamism and resulting complexity may represent its greatest challenge. Further clarification on what RRI has to offer in practice—beyond what has been offered to date—is still needed, as well as more explicit engagement with research and institutional cultures of responsibility. Such work may help to realise the high political expectations that are attached to nascent RRI. (shrink)

Though it seems rather surprising in retrospect, until about twenty-five years ago no philosopher in the Western tradition had explicitly formulated the question whether there could be an epistemic analogue to practical akrasia. Also surprisingly, despite the prima facie analogue with practical akrasia (the possibility of which is not much disputed), much of the recent work on this question has defended the rather bold view that epistemic akrasia is impossible. While the arguments purporting to show the impossibility of epistemic akrasia (...) have been criticized by some, I propose instead to make a head-on attack and defend the substantive view that epistemic akrasia is possible — indeed, actual. This leaves for another day the project of diagnosing exactly where the arguments for the impossibility of epistemic akrasia go wrong. Here, I content myself with trying to show that they must go wrong, since — as I will argue — epistemic akrasia is possible. (shrink)

Mathematical expressions for the entropyS, the average information gained per trial (Ī) from information theory, and the de Broglie cyclical action integralA from his reinterpretation of wave mechanics are shown to be similar. The importance of this observation in our understanding ofS andĪ is considered. Furthermore, the similarity in the mathematical form of these functions indicates a possible route to further interpretation of de Broglie'sA and the nature of his “hidden thermostat.”.

Modern semiotics is a branch of logics that formally defines symbol-based communication. In recent years, the semiotic classification of signs has been invoked to support the notion that symbols are uniquely human. Here we show that alarm-calls such as those used by African vervet monkeys (Cercopithecus aethiops), logically satisfy the semiotic definition of symbol. We also show that the acquisition of vocal symbols in vervet monkeys can be successfully simulated by a computer program based on minimal semiotic and neurobiological constraints. (...) The simulations indicate that learning depends on the tutor-predator ratio, and that apprentice-generated auditory mistakes in vocal symbol interpretation have little effect on the learning rates of apprentices (up to 80% of mistakes are tolerated). In contrast, just 10% of apprentice-generated visual mistakes in predator identification will prevent any vocal symbol to be correctly associated with a predator call in a stable manner. Tutor unreliability was also deleterious to vocal symbol learning: a mere 5% of “lying” tutors were able to completely disrupt symbol learning, invariably leading to the acquisition of incorrect associations by apprentices. Our investigation corroborates the existence of vocal symbols in a non-human species, and indicates that symbolic competence emerges spontaneously from classical associative learning mechanisms when the conditioned stimuli are self-generated, arbitrary and socially efficacious. We propose that more exclusive properties of human language, such as syntax, may derive from the evolution of higher-order domains for neural association, more removed from both the sensory input and the motor output, able to support the gradual complexification of grammatical categories into syntax.

This paper elaborates on the link between different types and degrees of experience that can be gone through within a form of life or collectivity—the so-called levels of immersion—and the development of distinct types of tacit knowledge and expertise. The framework is then probed empirically and theoretically. In the first case, its ‘predictions’ are compared with the accounts of novices who have gone through different ‘learning opportunities’ during a pre-operational training programme for running a huge nickel industrial plant in Brazil. (...) These are also analysed vis-à-vis the experience of an expert who has designed and experienced the outcomes of two pre-operational training sessions in the nickel industry before developing and managing the one discussed here. Theoretically, the framework is used to pinpoint exactly what interactional experts who have developed their expertise through linguistic socialisation alone are able to do as well as to analyse the case of technical connoisseurs. The results indicate that the proposed framework is useful. It supports the design and improvement of training programmes for the development of tacit knowledge while at the same time bringing about a refined analysis of claims concerning the abilities of types of experts and expertise.

How can we identify and estimate workers’ tacit knowledge? How can we design a personnel mix aimed at improving and speeding up its transfer and development? How is it possible to implement tacit knowledge sustainable projects in remote areas? In order to answer these questions, it is necessary to distinguish between types of tacit knowledge, to establish what they allow for and to consider their sources. It is also essential to find a way of managing the tacit knowledge ‘stock’ and (...) distribution within the workforce. In short, a conceptual framework is needed to manage tacit knowledge. Based on previous works and 2 years of action research, this paper introduces such a framework and describes its partial application to support the pre-operational training and hiring in a large industrial plant in Brazil. Two contributions emerge from the research. First, the concept of ‘levels of similarity’ is introduced as a means to qualify the experience of workers and estimate the associated tacit knowledge. Second, the capability of carrying out three types of judgement properly and speedily is put forward as being a core ability of those who possess what has been called ‘collective tacit knowledge’ (Collins in Organ Stud 28(2):257–262, 2007). In practical terms, the results indicate the opportunity for companies to capitalize on the experience and tacit knowledge of their workers in a systematic way and with due recognition. Ultimately, positive impacts are expected in their absorptive capacity as well as in their management and human resources systems, accident prevention, productivity and the development of sustainable projects in remote areas.

Disagreement as we find it in both the history and the contemporary practice of philosophy is an inadequately understood phenomenon. In this paper I outline and motivate the problem of disagreement, arguing that "hard cases" of disagreement confront us with an unresolved, and seemingly unresolvable, challenge to the rationality of philosophical discourse, thereby raising the specter of a worri-some form of metaphilosophical skepticism. A variety of responses and attempted evasions are considered, though none are found to be particularly satisfying: Thus, (...) the specter remains unexorcised. El desacuerdo que encontramos tanto en la historia como en la práctica contemporánea de la filosofía es un fenómeno mal entendido. En este trabajo hago un esbozo y aduzco los motivos del problema del desacuerdo, argumentando que los "casos difíciles" de desacuerdo nos confrontan con un problema sin resolver y al parecer sin posibilidad de resolverse, que pone en duda la racionalidad del discurso filosófico, y con lo cual surge el espectro de una preocupante forma de escepticismo metafilosófico. Examino varias respuestas y tentativas de evasiones, aunque ninguna de ellas es particularmente satisfactoria. Así, el espectro sigue sin ser exorcizado. (shrink)

O texto a seguir, intitulado “Ensaio Histórico sobre a Cavalaria e a Honra dos Modernos”, foi escrito durante a juventude de David Hume, certamente antes da publicação do Tratado da Natureza Humana. Ainda não há consenso inabalável sobre o ano em que esse ensaio foi produzido. John Hill Burton, que o publicou pela primeira vez, em 1846, considera que Hume o teria escrito em 1727, logo após deixar o Edimburgh College. J. Y. T. Greig propõe uma conjectura um pouco mais, (...) por assim dizer, elástica, considerando que o texto deve ter sido escrito no período de 1729 a 1734. (shrink)

I argue that we are subject to ‘aesthetic luck’ in four senses: constitutive, upbringing, sociogeographic, and circumstantial. I review evidence from our practices, philosophy, and science. I then consider what challenges aesthetic luck raises to the communicability of aesthetic judgments, the formation of one’s aesthetic character, and the goal of a life well lived, as well as possible answers to those challenges.

Supposing you were convinced by certain radical skeptical arguments that many of your beliefs were not justifiably believed by you, what stance could/should you adopt with regard to those skeptically-problematized beliefs? This paper explores a range of possible reactions, aiming to be reasonably comprehensive in coverage though admittedly suggestive rather than decisive in its treatment of each individual reaction. In considering this variety of responses we begin to see suggestive intimations of the ways in which radical skepticism could represent a (...) threat to our notions of cognitive self-mastery.

An argument against the rationality of desiring to go to heaven might be put in the form of a trilemma: (1) any state of being that both lasts eternally and preserves me as the person I am would be hellish and therefore would not be a state of being that I could have any reason to desire; (2) any state of being that lasts eternally and yet fails to preserve my personhood by turning me into a non-person would not be (...) a state of being that I (qua person that I am) could have any reason to desire; and (3) any state of being that lasts eternally and yet fails to preserve my personhood by turning me into some other person would not be a state of being that I (qua person that I am) could have any reason to desire. This paper offers defenses of each of the three horns of this trilemma and concludes that there is no rationally compelling reason for any human being to desire to go to heaven. (shrink)

In recent years some archaeological commentators have suggested moving away from an exclusively anthropocentric view of social reality. These ideas endorse elevating objects to the same ontological level as humans – thus creating a symmetrical view of reality. However, this symmetry threatens to force us to abandon the human subject and theories of meaning. This article defends a different idea. It is argued here that an archaeology of the social, based on human intentionality, is possible, while maintaining an ontology that (...) does not involve dualistic conceptions of reality. Building upon the philosophical work of Vincent Descombes, it is contended that humans are intentional actors and society is predicated on triadic relations that involve humans, objects and meanings. These relations can only be understood holistically, given that these relations are merely parts of a meta-narrative. These meta-narratives contain specific historical and social settings, and it is only within these settings that social relations are intelligible. (shrink)

In a recent paper (in Argumentation, 2006) Robert Talisse and Scott Aikin suggest that we ought to recognize two distinct forms of the straw man fallacy. In addition to misrepresenting the strength of an opponent’s specific argument (= the representation form), one can also misrepresent the strength of one’s opposition in general, or the overall state of a debate, by selecting a (relatively) weak opponent for critical consideration (= the selection form). Here I consider whether we as philosophy professors could (...) be seen as sometimes committing the selection form of the straw man through the performance of our regular teaching duties. (shrink)

This paper develops a programmatic 'theory sketch' of a new theory of humour, pitched at roughly the same level of detail, and intended to have roughly the same level of inclusiveness, as the other available philosophical "theories" of humour. I will call the theory I propose the distance theory. After an appeal to some intuitive illustrations of the distance theory's attractions, I move on to offer an analysis of observational comedy using the distance theory. I conclude the paper with some (...) speculative remarks about the possible connections between the practice of observational comedy and the discipline of philosophy. (shrink)

This study aims to map out the relationships that make up green innovation initiatives in Brazilian industry. The sample comprised 100 managers at manufacturing companies, most of them operating in the business of farm machinery and equipment and steel structures. To develop this study, Medeiros et al. study, mapping critical factors that drive the success of green product innovation and the paradigm of complexity, was used as a reference study. Based on the results, it was possible to identify that the (...) operational dynamic of the factors and variables that affect market success do not happen in an isolated or fragmented way; they occur systematically with different contingencies and structured basic and intermediate skills in order to meet the expectations of consumers, laws, and environmental legislation. Initially, the technological expertise factor was noted as very important for sustaining green product innovation. Furthermore, since proactive leaders are an important factor for successfully developing environmentally sustainable products, it must be added to technological expertise as the foundation for developing green innovation. After defining the basis for green product innovation, the intermediary conditions necessary for using the available technology appropriately were mapped out. In this sense, variables such as “elimination of cultural barriers,” “capacity for critical reflective analysis,” and “experimentation” are also very important. In addition, some of the variables of the cross-functional collaboration and market knowledge factors were a part of the structure that organizations need to transform potential into developing green products, which is the basis for the third level of the model. The fourth level of the model has the “meeting consumer expectations” and “following law and legislation” factors, which make up the main goals for developing environmentally sustainable products according to a number of surveys that were conducted.

‘Interactional expertise’ is developed through linguistic interaction without full scale practical immersion in a culture. Interactional expertise is the medium of communication in peer review in science, in review committees, and in interdisciplinary projects. It is also the medium of specialist journalists and of interpretative methods in the social sciences. We describe imitation game experiments designed to make concrete the idea of interactional expertise. The experiments show that the linguistic performance of those well socialized in the language of a specialist (...) group is indistinguishable from those with full blown practical socialization but distinguishable from those who are not well socialized. The imitation game can also be used to indicate whether an individual can enter an esoteric domain and master the interactional expertise, a skill required by interpretative sociologists of science, anthropologists, ethnographers, and the like.Keywords: Expertise; Interactional expertise; Imitation game; Turing test; Colour blindness; Interpretative methods.

Moral and financial scandals emerging in recent years around the world have created the momentum for reconsidering the role of virtuousness in organizational settings. This empirical study seeks to contribute toward maintaining this momentum. We answer to researchers’ suggestions that the exploratory study carried out by Cameron et al. :766–790, 2004 ), which related organizational virtuousness and performance, must be pursued employing their measure of OV in other contexts and in relation to other outcomes :928–958, 2007 ). Two hundred and (...) sixteen employees reported their perceptions of OV and their affective well-being at work, their supervisors reporting their organizational citizenship behaviors. The main finding is that the perceptions of OV predict some OCB both directly and through the mediating role of AWB. The evidence suggests that OV is worthy of a higher status in the business and organizational psychology literatures. (shrink)

In this paper I aim to do two things. First, I attempt to illustrate an interesting pattern of argument one can find in Hume's work. Next, I employ this Humean pattern of argument to show that IF there is a cogent and intuitive argument for any form of epistemological skepticism, which despite its cogency and intuitiveness has a unbelievable conclusion, THEN we lack a very important form of doxastic self-control, which I call rational self-control, over the beliefs problematized by that (...) skeptical argument. Thus, the challenge posed by skepticism is even deeper and more radical than commonly supposed: If any form of skepticism proves unanswerable and yet unbelievable, then we demonstrably lack RSC in the domain problematized by that form of skepticism. Thus, one's views on skepticism may entail definite views on doxastic self-control. (shrink)

In this paper I aim to address--and also to better understand--what is perhaps the most intuitive objection to Pyrrhonian skepticism, namely, that to completely suspend one's judgment is psychologically impossible. I propose to come to an understanding of Sextus's relation to this objection by trying to more clearly understand Sextus's claims about the "Skeptic". I hope to show that it is at least possible for us to understand Sextus and his claims about the "Skeptic" without being driven to either (1) (...) invoke restrictive interpretations of his claims or (2) adopt implausible hypotheses concerning his sincerity.
