CYBATHLON is an international championship where people with severe physical disabilities compete with the aid of state-of-the-art assistive technology. In one of the disciplines, the BCI Race, tetraplegic pilots compete in a computer game race by controlling an avatar with a brain-computer interface. This competition offers a perfect opportunity for BCI researchers to study long-term training effects in potential end-users, and to evaluate BCI performance in a realistic environment. In this work, we describe the BCI system designed by the team (...) Mirage91 for participation in the CYBATHLON BCI Series 2019, as well as in the CYBATHLON 2020 Global Edition. Furthermore, we present the BCI’s interface with the game and the main methodological strategies, along with a detailed evaluation of its performance over the course of the training period, which lasted 14 months. The developed system was a 4-class BCI relying on task-specific modulations of brain rhythms. We implemented inter-session transfer learning to reduce calibration time, and to reinforce the stability of the brain patterns. Additionally, in order to compensate for potential intra-session shifts in the features’ distribution, normalization parameters were continuously adapted in an unsupervised fashion. Across the aforementioned 14 months, we recorded 26 game-based training sessions. Between the first eight sessions, and the final eight sessions leading up to the CYBATHLON 2020 Global Edition, the runtimes significantly improved from 255 ± 23 s to 225 ± 22 s, respectively. Moreover, we observed a significant increase in the classifier’s accuracy from 46 to 53%, driven by more distinguishable brain patterns. Compared to conventional single session, non-adaptive BCIs, the inter-session transfer learning and unsupervised intra-session adaptation techniques significantly improved the performance. This long-term study demonstrates that regular training helped the pilot to significantly increase the distance between task-specific patterns, which resulted in an improvement of performance, both with respect to class separability in the calibration data, and with respect to the game. Furthermore, it shows that our methodological approaches were beneficial in transferring the performance across sessions, and most importantly to the CYBATHLON competitions. (shrink)

The development of neuropsychological assessment methods using virtual reality (VR) is a valid and promising option for the detection of cognitive impairment in the older people, focusing on activities composed of tasks of multiple demands. This study verified the association of age, schooling, and general cognitive status on the performance of neurologically healthy older adults in ECO-VR, a virtual reality task of multiple demands for neuropsychological assessment. A total of 111 older adults answered a sociodemographic questionnaire, the Mini Mental State (...) Examination, the Vocabulary subtest of the Wechsler Intelligence Scale for Adults (third edition), and the ECO-VR. Correlation analyses, multiple linear regression, and comparisons between groups (effects by age and schooling groups) were used to evaluate the results. The ECO-VR total score was significantly associated with age, years of education, MMSE, and Vocabulary subtest. The linear regression models identified that age was the main predictor for total score and rule breaking of ECO-VR. According to the univariate analysis, it was identified the main effect of age group and schooling group in the total ECO-VR score, but there was no interaction effect. The results are discussed in order to understand the role of sociodemographic characteristics in the performance of older adults in a virtual reality task of multiple demands. It was also verified the possibility use of virtual reality for neuropsychological assessment of older adults. (shrink)

Este texto trata da possível relação entre Filosofia para Crianças e "desaparecimento" da Infância, buscando especialmente em Matthew Lipman e Neil Postman o aporte teórico para pensar o papel da Filosofia perante uma infância em "desaparecimento". Diante da complexidade da temática, não temos a intenção de alcançar respostas, e sim instigar maiores reflexões.

This book argues that external world skepticism is false for straightforward reasons. To make this case it develops and defends a neglected methodological approach involving a distinctive process of first-person reflection. We begin within the practices, procedures, and commitments of ordinary life and science. We then seek some reason to think skepticism true, carefully scrutinizing all the most important arguments. Finding no reason to think it true and decisive reasons to think it false, we reject it. As the book shows, (...) this is a fully satisfactory refutation. No epistemological theorizing is needed. The book begins by exploring and defending this method in seminal works of G. E. Moore and J. L. Austin. Turning to contemporary epistemology, it asks why we shouldn't appeal to considerations about the world when responding to skeptical argumentation. No good reason is found, despite exploration of a wide range of central issues in recent epistemology. To the contrary, perfectly ordinary examples indicate that it is correct to reject the skeptical scenarios - the dreaming worry, Descartes' evil demon, the brain-in-a-vat - by appealing to things we know about the world. Likewise, considerations about sensory perception do not provide any reason to think our evidence excludes considerations about the world. Along the way, methodological lessons are drawn from consideration of the most important skeptical arguments in the contemporary literature. The book concludes by defending the satisfactoriness of its approach. What emerges is a new understanding of what philosophical illumination might look like in relation to core epistemological issues. (shrink)

This article is the lead piece in a special report that presents the results of a bioethical investigation into chimeric research, which involves the insertion of human cells into nonhuman animals and nonhuman animal embryos, including into their brains. Rapid scientific developments in this field may advance knowledge and could lead to new therapies for humans. They also reveal the conceptual, ethical, and procedural limitations of existing ethics guidance for human‐nonhuman chimeric research. Led by bioethics researchers working closely with an (...) interdisciplinary work group, the investigation focused on generating conceptual clarity and identifying improvements to governance approaches, with the goal of helping scholars, funders, scientists, institutional leaders, and oversight bodies (embryonic stem cell research oversight [ESCRO] committees and institutional animal care and use committees [IACUCs]) deliver principled and trustworthy oversight of this area of science. The article, which focuses on human‐nonhuman animal chimeric research that is stem cell based, identifies key ethical issues in and offers ten recommendations regarding the ethics and oversight of this research. Turning from bioethics’ previous focus on human‐centered questions about the ethics of “humanization” and this research's potential impact on concepts like human dignity, this article emphasizes the importance of nonhuman animal welfare concerns in chimeric research and argues for less‐siloed governance and oversight and more‐comprehensive public communication.

This study aims to investigate assortative mating based on mate value from male perspective. Male participants (132 Brazilian and 106 American) evaluated hypothetical “stimulus” males described in terms of physical attractiveness, social skills, and social status (each varied in high or low levels). Participants rated each stimulus and each stimulus' preferred mating partner on nine traits. The results showed that (1) positive assortative mating was expected in romantic relationships; (2) the stimulus ratings did not vary independently, suggesting that mate value (...) is the result of the interaction of the characteristics of individuals; and (3) that participants expected physically attractive and healthier female partners to pair with high-status male stimuli. The American and Brazilian mating expectations were similar, minor differences indicate that Brazilian participants considered men with high levels of social skills to be more ambitious and intelligent; American participants expected men of high status to be healthier; Brazilians expect men of high status to have more attractive faces, while Americans expected these men to possess more attractive bodies; and Brazilian participants assigned more attractive bodies to men of lower status. These differences reflect the influence of economic and cultural factors on the local environment. The study contributes to the understanding of the construction of market value and reveals that male expectations are in line with human mating preferences. The investigation of mating expectations can be a rich approach to investigate socio-cultural aspects that are related to mating in different cultures. (shrink)

J. L. Austin’s attitude towards traditional epistemological problems was largely negative. They arise and are maintained, he charged, by “sleight of hand,” “wile,” “concealed motives,” “seductive fallacies,” fixation on a handful of “jejune examples” and a host of small errors, misinterpretations, and mistakes about matters of fact (1962: 3- 6, 1979: 87). As these charges indicate, he did not offer a general critical theory of traditional epistemological theorizing or of the intellectual motivations that lead to it. Instead, he subjected individual (...) arguments to piecemeal criticism, patiently showing how things go awry in conception, motivation, argumentation, and plain fact. The work was incremental, but the goal was radical: to reduce large edifices to rubble. As he put it regarding certain sense datum theories, “the right policy is to go back to a much earlier stage, and to dismantle the whole doctrine before it gets off the ground” (1962: 142). It is often said that Austin’s criticisms were linguistic, but this is only partly right. While he occasionally charges traditional epistemologists with misusing crucial words and relying on unregulated and inadequately motivated technical terms, he also charges them with factual errors and with distorting or misunderstanding the procedures involved in epistemically evaluating people’s claims and beliefs. For this reason, it is best to see Austin as criticizing traditional epistemological puzzles and projects from the point of view of our ordinary lives (including our best scientific theories and practices). He starts with a commitment to our ordinary ways of using words, our ordinary convictions about.. (shrink)

The Afro-Brazilian connections between the coast of West Africa and Brazil date back to the transatlantic slave trade and the Muslim uprising in Bahia in 1933. After this major rebellion, many former slaves returned to West Africa bearing a large Brazilian cultural imprint consisting of architectural skills, culinary traditions, and song and dance. They also brought back Brazilian names and cosmopolitan outlooks. From Africa, enslaved Africans carried with them to Brazil philosophical and cosmological outlooks and indeed, culture generally. Some of (...) these cross-fertilizations are what are interrogated in this intellectual and cultural exchange. (shrink)

It is always possible to construct a real function f, given random quantities X and Y with continuous distribution functions F and G, respectively, in such a way that f(X) and f(Y), also random quantities, have both the same distribution function, say H. This result of De Finetti introduces an alternative way to somehow describe the `opinion' of a group of experts about a continuous random quantity by the construction of Fields of coincidence of opinions (FCO). A Field of coincidence (...) of opinions is a finite union of intervals where the opinions of the experts coincide with respect to that quantity of interest. We speculate on (dis)advantages of Fields of Opinion compared to usual `probability' measures of a group and on their relation with a continuous version of the well-known Allais' paradox. (shrink)

Establishing the basic knowledge, methodology, and technology for a framework for the continuous decoding of hand/arm movement intention was the aim of the ERC-funded project “Feel Your Reach”. In this work, we review the studies and methods we performed and implemented in the last 6 years, which build the basis for enabling severely paralyzed people to non-invasively control a robotic arm in real-time from electroencephalogram. In detail, we investigated goal-directed movement detection, decoding of executed and attempted movement trajectories, grasping correlates, (...) error processing, and kinesthetic feedback. Although we have tested some of our approaches already with the target populations, we still need to transfer the “Feel Your Reach” framework to people with cervical spinal cord injury and evaluate the decoders’ performance while participants attempt to perform upper-limb movements. While on the one hand, we made major progress towards this ambitious goal, we also critically discuss current limitations. (shrink)

O presente artigo tem como objetivo principal caracterizar o legado de J. Chasin sobre o estatuto ontológico marxiano e a sua respectiva resolução metodológica. Para tanto, serão analisados os temas específicos que compõem a proposta inovadora do autor. São eles: a análise imanente; o significado do estatuto ontológico marxiano propriamente dito, que inclui a afamada tese das “três fontes”, como modo tradicional de atribuir às origens do pensamento de Marx; o caráter metodológico aí decorrente; as possíveis consequências da proposta chasiniana, (...) sobretudo, no que diz respeito à “metapolítica”, a formação da individualidade e, por fim, a denúncia dos limites teóricos de Lukács, principalmente em relação à “dialética do universal do articular e do singular”, que somados a outros percalços, sustenta o “vínculo lógico entre para Marx e Hegel” presente em determinas obras do filósofo húngaro.

This work empirically tests the concept of the ‘whistleblowing triangle,’ which is modeled on the three factors encapsulated by the fraud triangle, in the Indonesian context. Anchored in the proposition of an original research framework on the whistleblowing triangle and derived hypotheses, this work aims to expand the body of knowledge on this topic by providing empirical evidence. The sample used is taken from audit firms affiliated with both the big 4 and non-big 4 companies operating in Indonesia. The results (...) of analysis using the PLS-PM method found a significant relationship between the components of the whistleblowing triangle and the intention of blowing the whistle. We found that financial incentives are the most significant predictor of auditors’ intention to blow the whistle in Indonesia. Other components, such as opportunity and rationalization, also play an important role in supporting auditors’ intention to blow the whistle. Our findings also suggest that related pressures are the top priority for audit firms in Indonesia to consider in increasing whistleblowing intention. We expand the previous literature on whistleblowing which has been derived from the components of the fraud triangle :28–56, 2016; Smaili and Arroyo in J Bus Ethics, https://doi.org/10.1007/s10551-017-3663-7, 2017) by adding empirical evidence.

The paper deals with the approach to the so called psychophysical unity as deve_loped by the Slovak philosopher Svätopluk Štúr in the 1940s. The approach is examined in the context of current conceptions of psychophysical reductionism, parallelism and interactionalism. The author shows S. Štúr as indicating the possible resolution in his philosophy of the "organic whole".

During the last decades the special literature has paid relatively much attention to the problematic of speech acts. However, in Slovakia it still remains underdeve-loped. Therefore the author decided to examine it from the points of view of its establishment, gradual development and interactional communication. The paper offers a survey of all philosophical-linguistic views on this problematic. Further, it gives a more detailed analysis of the theory of the founders of the speech acts theory , comparing their main ideas with (...) those of other philosophers and linguists. (shrink)

The article uses research carried out on three Extractivist Reserves in the Brazilian Amazon to “test” the distinction proposed by Bruno Latour (Où atterrir?) between territories of production and territories in begetting on which the social question challenges the environmental question in a context of ambientalizaçao (Leite Lopes, 2006). These analyzes are inspired by a grid proposed by Claude Lefort (Essais sur le Politique) to respond to the “challenges of the democratic revolution”.
