This paper addresses word learning for human–robot interaction. The focus is on making a robotic agent aware of its surroundings, by having it learn the names of the objects it can find. The human user, acting as instructor, can help the robotic agent ground the words used to refer to those objects. A lifelong learning system, based on one-class learning, was developed. This system is incremental and evolves with the presentation of any new word, which acts as a class to (...) the robot, relying on instructor feedback. A novel experimental evaluation methodology, that takes into account the open-ended nature of word learning, is proposed and applied. This methodology is based on the realization that a robot’s vocabulary will be limited by its discriminatory capacity which, in turn, depends on its sensors and perceptual capabilities. The results indicate that the robot’s representations are capable of incrementally evolving by correcting class descriptions, based on instructor feedback to classification results. In successive experiments, it was possible for the robot to learn between 6 and 12 names of real-world office objects. Although these results are comparable to those obtained by other authors, there is a need to scale-up. The limitations of the method are discussed and potential directions for improvement are pointed out. (shrink)

This article presents the results of a systematic literature review on religiosity and spirituality, particularly in the work context. We aimed to verify the state-of-the-art of scientific production related to these themes. To achieve the proposed objective, we identified 312 articles published in journals in the period between 1960 and 2018 using a rigourous method of analysis and sorting, which resulted in 52 appropriate studies. The analyses presented are based on the three bibliometric laws: those of Lotka, Bradford and Zipf. (...) This article brings contributions that encompass four approaches: measurement scales of spirituality and religiosity; behavioural benefits of religiosity in individuals; insertion of religiosity and spirituality in social service practice; and research directions. This research presents technical and managerial implications to provide theoretical support for the creation of programmes and/or practices of spirituality and religion in the workplace as an effective strategy, towards ethical attitudes. Also, this study contributes to the methodological achievement of SLRs in the field of religion in the workplace, highlighting an effective method for thematic mapping, and holistically identifying new research topics and directions, especially because of the several guidelines presented.

Neste artigo abordaremos a questão da mentira, em Kant, vinculando a questões de ordem moral. Pois, sendo a ética e o direito ramos da moral, o problema da mentira encontra-se em saber se ela é uma questão ética ou jurídica, ou se é um problema moral, que engloba tanto a ética como o direito, que não legitimam tal ato. Iniciaremos esta unidade com a análise dos conceitos de moral, ética e direito buscando compreender o que constitui cada um desses campos (...) da cultura e qual a distinção entre ambos. Em seguida trataremos, em especial, da questão da mentira na filosofia prática de Kant, abordando o seu posicionamento ético sobre o ato de mentir, onde é levantada a questão em saber se uma falsa declaração pode ser legitimada ou não. Por fim, analisaremos o debate entre Kant e Benjamim Constant, sobre a problemática da mentira, onde será tratada a questão de um suposto direito de mentir e dos princípios gerais e intermediários, a saber, se é possível a aplicação de um princípio geral de forma absoluta isolada sem o auxílio de princípios intermediários.

The reflection proposed in this article aims to briefly consider philosophy and literature on the saga of Genoveva Pia in the early morning cadence of the drums of São Luís (1975), a novel by the great poet from Maranhão, Josué Montello (1917-2006), in which a narrative is made between fiction and the reality of the Brazilian colonial slave period on the historical soil of São Luís, Ma. To this end, the text is divided into two parts: firstly, it (...) looks at the dialectic between history as representative and memory as an actualizable, individual and collective phenomenon that takes shape between spaces, events, memories and forgetfulness and, secondly, it highlights the importance of the saga of the black woman Genoveva Pia, from persistence to resistance in welcoming, protecting and freeing the black men and women, recalling the ancestry of the freed black man Damião, the novel’s central character and narrator.

There are numerous studies that, from different perspectives, have dealt with the debate held in the Spanish Empire during the 16th century on the slavery of the American Indians, starring –among others– by Francisco de Vitoria and his disciples from the School of Salamanca, and also –outside the academic sphere– by Fray Bartolomé de las Casas and Juan Ginés de Sepúlveda. The purpose of this work is to study whether this debate made its mark in Spanish society. For this, it (...) is analyzed three theatrical pieces from the Golden Age signed by playwrights of the stature of Tirso de Molina, Lope de Vega and Pedro Calderón de Barca, who –given their enormous popularity– had the capacity to reach the wide audience that congregated in the corrals of comedies. Were these three writers influenced by the controversy over the Indians carried out, among other authors, by Vitoria, Las Casas and Sepúlveda? Did they fully grasp in their works the subtle debate that Vitoria, Las Casas and Sepúlveda maintained when they interpreted Aristotelian arguments on slavery and the consequences that derived from them in terms of the possibility of enslaving or not the Indians?

El artículo estudia la tercera y última confrontación con el Tratado de la libertad de Schelling que Heidegger sostuvo en 1941. El objetivo consiste en explicar el contexto del problema del acabamiento de la metafísica del idealismo alemán, para analizar la posición que tiene Heidegger de las nociones de diferencia y voluntad forjadas por la filosofía tardía de Schelling; de esta manera, a partir del abismo de la voluntad se muestra la intersección entre la filosofía de la libertad de Schelling (...) y la ontología del evento de Heidegger.

There are currently serious concerns that published scientific findings often fail to be reproducible, and that some solutions may be gleaned by attending the several methodological and sociological recommendations that could be found in the literature. However, researchers would also arrive at some answers by considering the advice of the philosophy of science, particularly semantics, about theses on truth related to scientific realism. Sometimes scientists understand the correspondence thesis of truth as asserting that the next unique empirical confirmation of a (...) hypothesis suffices to attribute truth to it provisionally. Such empiricist bias is not necessarily at the core of CTT, but Mario Bunge proposed the synthetic thesis of truth, based on CTT, to explicitly avoid the bias. STT requires considering a hypothesis corroborated, both by purely empirical confirmation and external consistency or compatibility with the bulk of existing background knowledge. While a capricious understanding of CTT could be rigged to recommend the “one shot game” in hypothesis testing, STT clearly demands the use of multiple approaches, empirical as well as theoretical, and it asserts that a scientific test is effective to the extent to which it is neither purely empirical, nor viewed in isolation. Pattern consistency together with an understanding of causal relations make confirmed hypotheses robust and more reliable. The militancy of the double mechanism of hypothesis control of STT can help mitigate the reproducibility crisis. Earl Werner’s research program in community ecology is an example of the use of STT criteria, which leads to the development of reliable, cross-checked, ecological results, with high predictive capacity.

The rating of perceived exertion can be used to monitor the exercise intensity during laboratory and specific tests, training sessions, and to estimate the internal training load of the athletes. The aim of the present study was to develop and validate a specific pictorial perceived exertion scale for soccer players called GOAL Scale. The pictorial GOAL Scale was validated for twenty under-17 soccer players. In the validation phase, the athletes were evaluated in a progressive protocol involving stimuluses of 3 min (...) with 1 min for the rest into the stages until the voluntary exhaustion in Maximal Cardiopulmonary Effort Test, and in the Yo Yo Intermittent Recovery Test – Level 1. The RPE identified by the GOL Scale, by the Borg Scale 6 – 20 and by the Cavasini Scale, as well as the heart rate, perceptual of the heart rate and the blood lactate concentration were immediately evaluated after each stage of both tests. Spearman’s correlation coefficient was used. Construct scale validity was examined by regressing GOAL Scale against Borg Scale 6 – 20 and Cavasini Scale and concurrent scale validity was investigated by regressing GOAL Scale against HR, beats/min and blood lactate concentration during two progressive tests. There was a significant correlation values of the GOAL Scale with Borg Scale, Cavasini Scale, %HRmax, HR and lactate during tests. The results evidenced concurrent and construct validity of the GOAL Scale across a wide range of exercise intensity. The absence of verbal anchors makes the use of this instrument to soccer, futsal and beach soccer athletes of different languages and different literacy levels possible. (shrink)

As we turn to the lived experience of memory, we are confronted with an eerie and enigmatic possibility: the possibility to remember what we ourselves never lived. How to explain phenomenologically this enigmatic but fundamental level of spatialized memory? I would like to come back to these issues in order to face yet another fundamental question: Does a phenomenology of spatialized memory require any onto-phenomenological concretizations?

Conceito oriundo do debate a respeito do movimento, o conatus, entendido como inclinação ou esforço, será um dos temas centrais da física seiscentista. Este artigo pretende explicitar o contexto de elaboração do conceito de conatus no século XVII, ou pelo menos na obra de três de seus principais filósofos: Descartes, Hobbes e Espinosa. Em Descartes, o conceito de conatus ainda se separa do conceito de movimento propriamente dito. Tal separação desaparece em Hobbes, para quem o conatus será apresentado como um (...) movimento ínfimo, com consequências não só para a Física, mas também para a Ética e a Política. Com Espinosa, por sua vez, o conceito ganhará contornos nitidamente ontológicos, tornando-se a chave para entender a essência das coisas singulares. (shrink)

La cuestión de las relaciones entre la búsqueda espiritual y el enraizamiento histórico y social de la acción humana, ha inquietado desde siempre a las personas que anhelan vivir con plenitud de sentido su propia existencia. Siguiendo la tradición de las grandes religiones, el artículo reflexiona en torno a dos afirmaciones complementarias, cuya unidad nos importa fundamentar analíticamente: «No hay acción social auténtica sin espiritualidad; no hay verdadera espiritualidad sin acción social consecuente». Lo difícil –se agrega- es construir este nexo (...) en la vida y mantenerlo. El autor conceptualiza el emprendimiento como un desarrollo humano integral y lo postula como el camino más seguro, por el que podemos avanzar. (shrink)

The goal of this article is to discuss several critical positions published recently in academic journals on the book The order of ‘Capital’, which aim is to lay the foundations for a republican reading of Marx’s major work. The core of the argument focuses against any attempt to derive normative proposals from scientific discoveries. From here, clarifying some key concepts and positions of the republican tradition is a necessary condition in order to show the close solidarity between Marx and Kant (...) about the formal and institutional conditions of any possible theory of justice.

No prefácio da segunda edição da Crítica da razão pura, Kant propõe uma revolução metodológica em Filosofia similar à revolução copernicana: ao invés de tratar o observador como um centro fixo em torno do qual os objetos gravitam, pensá-lo antes como um móvel cujos movimentos cognitivos permitiriam explicar fenômenos anteriormente inexplicáveis. Alguns filósofos contemporâneos sugerem que essa revolução deva ser realizada de um ponto de vista geográfico, pois os problemas fundamentais da Filosofia parecem gravitar todos em torno do mesmo centro (...) fixo, o qual não é confrontado à fragilidade de sua posição geográfica contingente, o centro europeu. O objetivo deste artigo é reconstruir as linhas gerais dessa nova revolução copernicana como um procedimento de reavaliação de três vetores centrais do saber: o Eu, o Outro e o Todo. (shrink)

RESUMEN Este trabajo propone una reflexión sobre la técnica y sobre las condiciones de una crítica de la técnica en el horizonte contemporáneo del agotamiento de los paradigmas humanistas desde los que tradicionalmente se pensó esa crítica. Se plantea que la pregunta por la técnica ha de diferenciarse de la pregunta por los dispositivos técnicos, es decir, ha de partir de la ruptura con el supuesto humanista de la exterioridad entre técnica y humanidad. Una vez planteada esta escena poshumanista se (...) proponen distintas alternativas posibles en ese horizonte, que oscilan entre el cinismo antropotécnico y el experimentalismo radical postidentitario. Finalmente, este postula que la puesta en disposición del lenguaje y de la temporalidad son los parámetros clave del contemporáneo capitalismo de la información. Ante ello, se propone que el desafío fundamental de un poshumanismo radical es abrir una experiencia del lenguaje y del tiempo más allá de toda forma de disponibilidad. ABSTRACT This paper proposes a reflection on technology and on the conditions of a critique of technology in the contemporary horizon of the exhaustion of the humanistic paradigms from which that criticism was traditionally formulated. The argument states that the question about technique should be distinguished from the question about technical devices, i.e., it must break with the humanist assumption of the exteriority between technology and humanity. Once assumed this posthumanist scene, the paper analyzes different possible positions in that scene, ranging from anthro-potechnical cynicism to radical post-identitarian experimentalism. Finally, the paper postulates that the making available of language and temporality are the main parameters of contemporary capitalism ofinformation. In response, the fundamental challenge of a radical posthumanism is to open an experience of language and of temporality outside any form of availability. (shrink)
