Therapeutic strategies capable of inducing and enhancing prosthesis embodiment are a key point for better adaptation to and acceptance of prosthetic limbs. In this study, we developed a training protocol using an EMG-based human-machine interface that was applied in the preprosthetic rehabilitation phase of people with amputation. This is a case series with the objective of evaluating the induction and enhancement of the embodiment of a virtual prosthesis. Six men and a woman with unilateral transfemoral traumatic amputation without previous use (...) of prostheses participated in the study. Participants performed a training protocol with the EMG-based HMI, composed of six sessions held twice a week, each lasting 30 mins. This system consisted of myoelectric control of the movements of a virtual prosthesis immersed in a 3D virtual environment. Additionally, vibrotactile stimuli were provided on the participant’s back corresponding to the movements performed. Embodiment was investigated from the following set of measurements: skin conductance response, crossmodal congruency effect, ability to control the virtual prosthesis, and reports before and after the training. The increase in the skin conductance response in conditions where the virtual prosthesis was threatened, recalibration of the peripersonal space perception identified by the crossmodal congruency effect, ability to control the virtual prosthesis, and participant reports consistently showed the induction and enhancement of virtual prosthesis embodiment. Therefore, this protocol using EMG-based HMI was shown to be a viable option to achieve and enhance the embodiment of a virtual prosthetic limb. (shrink)

Pandemics are faced with uncertain scenarios, environmental, economic and/or social crises, generating negative impacts on society, which are further aggravated in a context of social vulnerability. This text aims to present and reflect on the transformation of a pandemic into a syndemic in Brazil due to the consequences of social vulnerability. How and why can a pandemic turn into a syndemic given the consequences of social vulnerability that plague Brazil? Understanding the factors and effects of social vulnerability, as well as (...) the consequences of social vulnerability in Brazil, lead to the search for new sustainable dynamics in the face of crises and uncertainties through global action and an education aimed at dealing with the challenges of vulnerability.

This paper is about even in downward entailing contexts. Karttunen and Peters (1979) have shown that there are two different sets of implicatures of even in such contexts. They argue that the two sets of implicatures are derived by allowing even to take scope either higher or lower than a negative polarity licenser. Rooth (1985) argues that even is lexically ambiguous, that is, there is a negative polarity even. I argue against Rooth's ambiguity theory and show that within Rooth's theory (...) of focus, a scope theory of even has better empirical coverage. I also answer objections to the scope theory raised by Rooth (1985) and Karttunen and Karttunen (1977). (shrink)

Little is known empirically about the role of supervisor listening and the emotional conditions that listening facilitates. Having the opportunity to speak is only one part of the communication process between employees and supervisors. Employees also react to whether they perceive the supervisor as actively listening. In two studies, this paper examines three important outcomes of employee perceptions of supervisor listening. Furthermore, positive and negative affect are investigated as distinct mediating mechanisms. Results from Study 1 revealed that employee perceptions of (...) supervisor listening reflected supervisors’ self-ratings of how they listen to their employees and these perceptions were associated with the three work outcomes. Study 2 replicated the findings in a larger sample and found evidence for two explanatory mechanisms. Positive affect mediated the effects of perceived supervisor listening on organizational citizenship behavior and turnover intention, whereas negative affect mediated listening effects on emotional exhaustion and turnover intention. Implications for organizational research and managerial practice concerning workforce sustainability are discussed. (shrink)

Political Insults proposes a theory of international insult that focuses on interrelations between social identity and power. The book analyses conflicts between the U.S. and North Korea, sovereignty contestations around islands in the Japanese sea, Pussy Riot in Russia, veterans in Ukraine, and Nagorno-Karabakh.

This study explored the effect of attitude towards entrepreneurship, need for achievement, risk-taking propensity, proactive personality, self-efficacy, opportunity recognition competency, entrepreneurship education, uncertainty avoidance, and entrepreneurial knowledge on entrepreneurial intention among university students in Malaysia. This quantitative study had adopted the cross-sectional design approach and involved 391 university students in Malaysia via the online survey. The study outcomes revealed that the NFA, PRP, and SLE significantly affect students’ attitudes towards entrepreneurship. Moreover, entrepreneurship education and UNA significantly affect ORC. Finally, ATE (...) has a positive and significant effect on ENIN among university students in Malaysia. As entrepreneurship offers an alternative career path for people seeking economic prosperity and addressing social issues, including unemployment, the government should formulate effective policies and regulations that support entrepreneurship activities. Universities and other institutions should play a pivotal role in providing the proper exposure via entrepreneurship education while honing the essential traits for a career in entrepreneurship.

Alan Turing, one of the fathers of computing, warned that Artificial Intelligence (AI) could one day pose an existential risk to humanity. Today, recent advancements in the field AI have been accompanied by a renewed set of existential warnings. But what exactly constitutes an existential risk? And how exactly does AI pose such a threat? In this chapter we aim to answer these questions. In particular, we will critically explore three commonly cited reasons for thinking that AI poses an existential (...) threat to humanity: the control problem, the possibility of global disruption from an AI race dynamic, and the weaponization of AI.

Este artigo busca aliar as leituras de Adorno e Dewey acerca do papel da educação frente o fenômeno da alienação social, focando principalmente a experiência dentro do processo de emancipação. Ao final, busca-se identificar os ideais de coletividade e compromisso como premissas falsas dos processos educacionais.

Este artículo estudia los números de la Revista de Psicoanálisis publicados entre 1946 y 1955 en Argentina. En particular, analiza los artículos escritos por los psicoanalistas argentinos que allí aparecen y las notas e informaciones que se incluyen en las últimas páginas de la revista. Se propone, por un lado, rastrear qué es el psicoanálisis en esos años, pensando este saber como un objeto discursivo, y, por el otro, indagar sobre el modo en que se construye la comunidad discursiva psicoanalítica (...) de la APA. Este recorrido ha evidenciado, por un lado, que el psicoanálisis es entendido, en ese entonces, como una teoría científica y una práctica contigua a la práctica médica, limitado al tratamiento individual. Por el otro, ha identificado que la revista, además de constituir un medio de comunicación privilegiado para la institución, contribuye a la consolidación de la comunidad discursiva psicoanalítica.

This paper proposes a theoretical approach to discuss the relations among reality, chemists’ interactions with it, and the resulting interpretation and representation of the acquired scientific knowledge. Taking into account that such relations are of semiotic nature, this paper aims at discussing in the light of Peirce’s theory of signs different descriptions of chemical activity and chemical education proposed by Alex Johnstone and elaborated by other science educators. In order to discuss the contributions and limitations of the proposed theoretical framework, (...) and considering its potential interest for chemical education, an example on the communication strategies for the content ‘vapour pressure’ found in twentieth-century general chemistry university textbooks is also presented.

O jurista britânico John Austin está inserido no limiar do desenvolvimento da tradição juspositivista. Sua obra, que data da primeira metade do século XIX, foi especialmente importante para a fixação dos elementos básicos dessa vertente do pensamento jurídico. Entre suas contribuições para a doutrina juspositivista está a sua formulação da tese da separação entre o direito e a moral. No âmbito ético, por seu turno, John Austin foi um fervoroso utilitarista e defendeu a utilização do princípio da utilidade como o (...) único critério racional para o desvelamento das normas morais superiores (as leis divinas). Considerando essas duas dimensões do seu pensamento, há muito se questiona se a sua ética utilitarista teria influenciado, de algum modo, a sua teoria jurídica, especialmente no que tange à tese da separação. Esta última, que está no centro da tradição juspositivista, tem sido interpretada de diferentes modos no debate jurídico contemporâneo. Uma vertente em especial, o chamado positivismo ético, abriu novas perspectivas para o estudo dessa tradição, ao defender a teoria juspositivista como um modelo teórico moralmente satisfatório para os sistemas jurídicos contemporâneos. Desse modo, utilizando a premissa central do positivismo ético (de que existem razões morais para a defesa da tese da separação) como instrumento metodológico- interpretativo, pretende-se retomar a questão da relação entre as convicções éticas e jurídicas de John Austin, a fim de compreender quais foram as razões morais que o levaram a defender a separação entre o que é o direito e aquilo que ele deveria ser.

Vehicle externalism maintains that the vehicles of our mental representations can be located outside of the head, that is, they need not be instantiated by neurons located inside the brain of the cogniser. But some disagree, insisting that ‘non-derived’, or ‘original’, content is the mark of the cognitive and that only biologically instantiated representational vehicles can have non-derived content, while the contents of all extra-neural representational vehicles are derived and thus lie outside the scope of the cognitive. In this paper (...) we develop one aspect of Menary’s vehicle externalist theory of cognitive integration—the process of enculturation—to respond to this longstanding objection. We offer examples of how expert mathematicians introduce new symbols to represent new mathematical possibilities that are not yet understood, and we argue that these new symbols have genuine non-derived content, that is, content that is not dependent on an act of interpretation by a cognitive agent and that does not derive from conventional associations, as many linguistic representations do.

La crisis sanitaria ocasionada por la expansión del Covid-19 pone en evidencia las consecuencias que tiene sobre la vida común la mercantilización de lo público y el mercado como eje regulador de la vida y de las relaciones humanas. El contexto actual demostró la cadena de inequidades que enfrentan las mujeres en la región, pudiendo identificarse al menos tres dimensiones en las que se expresa esta desigualdad: los cuidados, el trabajo y la violencia. Es menester de este artículo realizar un (...) estudio del impacto de la pandemia en estas tres dimensiones, buscando aportar a la reflexión para la acción que permita repensar un mundo pospandemia, donde la perspectiva de género no se constituya como una agenda coyuntural de los gobiernos, sino como un elemento fundamental en la transformación de nuestras sociedades. Este artículo es fundamentalmente descriptivo, utilizando para su análisis la información de datos secundarios, principalmente cuantitativos, de diferentes fuentes de información; por tanto se trata de datos recolectados, procesados, analizados y publicados con propósito diferente a los objetivos de este artículo. Las principales fuentes de información han sido ONU, OIT, CEPAL, ONU MUJERES, UNESCO y ACNUR. (shrink)

JUSTIÇA RESTAURATIVA: UMA ANÁLISE SOCIOLÓGICA DOS FINS QUE OS MEIOS PUNITIVOS NÃO ALCANÇAM.

Technological advances are bringing new light to privacy issues and changing the reasons for why privacy is important. These advances have changed not only the kind of personal data that is available to be collected, but also how that personal data can be used by those who have access to it. We are particularly concerned with how information about personal attributes inferred from collected data (such as online behaviour), can be used to tailor messages and services to specific individuals or (...) groups. This kind of ‘personalised targeting’ has the potential to influence individuals’ perceptions, attitudes, and choices in unprecedented ways. In this paper, we argue that because it is becoming easier for companies to use collected data for influence, threats to privacy are increasingly also threats to personal autonomy—an individual’s ability to reflect on and decide freely about their values, actions, and behaviour, and to act on those choices.4 While increasing attention is directed to the ethics of how personal data is collected, we make the case that a new ethics of privacy needs to also think more rigorously about how personal data may be used, and its potential impact on personal autonomy.

En este trabajo ofrezco una elucidación de la normatividad de lo mental en términos de la perspectiva de segunda persona, con la esperanza de abrir un horizonte conceptual que nos permita ir más allá de Donald Davidson. A tal efecto, el artículo tiene la siguiente estructura. En la primera parte presento su original respuesta al problema mente/cuerpo y reconstruyo su argumentación a favor de la tesis de la irreducibilidad de los conceptos mentales. En la segunda parte me ocupo del rasgo (...) que, en su sistema, porta la peculiaridad de lo mental, a saber: la normatividad. En la tercera sección exploro y evalúo el tratamiento davidsoniano de las perspectivas de primera, segunda y tercera persona con vistas a precisar, finalmente, mi propuesta. (shrink)

Andy Clark and David Chalmers (1998) argue that certain mental states and processes can be partially constituted by objects located beyond one’s brain and body: this is their extended mind thesis (EM). But they maintain that consciousness relies on processing that is too high in speed and bandwidth to be realized outside the body (see Chalmers, 2008, and Clark, 2009). I evaluate Clark’s and Chalmers’ reason for denying that consciousness extends while still supporting unconscious state extension. I argue that their (...) reason is not well grounded and does not hold up against foreseeable advances in technology. I conclude that their current position needs re-evaluation. If their original parity argument works as a defence of EM, they have yet to identify a good reason why it does not also work as a defence of extended consciousness. I end by advancing a parity argument for extended consciousness and consider some possible replies. (shrink)

Corporate governance is an issue of growing importance in developing economies, as many firms pass through significant transformations due to the combined forces of sociopolitical changes, technological progress and economic trends toward globalization. These elements, along with the structural characteristics of developing economies such as less developed capital markets and governmental interventionism, draw a picture for corporate governance practices that may, in some aspects, be fundamentally different from the practices found in European or North American contexts. In this paper we (...) review and discuss the state of corporate governance practices in Brazil, focusing on how the governance structure of Brazilian firms has been subjected to important changes in the recent past and how even more changes are expected to happen.

Ethics regulation for human-subject research has been established for about 20 years in Brazil. However, compliance with this regulation is controversial for non-biomedical sciences, particularly for human and social sciences, the source of a recent debate at the National Commission for Research Ethics. We hypothesized that for these fields, formal requirements for compliance with HSR regulation in graduate programs, responsible for the greatest share of Brazilian science, would be small in number. We analyzed institutional documents from 171 graduate programs at (...) six prestigious Brazilian universities in São Paulo and Rio de Janeiro, the states that fund most of the science conducted in Brazil. Among these programs, 149 were in HSS. The results suggest that non-compliance with standard regulation seems to be the rule in most of these programs. The data may reflect not only a resistance from scientists in these fields to comply with standard regulations for ethics in HSR but also a disciplinary tradition that seems prevalent when it comes to research ethics in HSR. However, recent encounters between Brazilian biomedical and non-biomedical scientists for debates over ethics in HSR point to a changing culture in the approach to research ethics in the country.

This article will look closely at the performance of tomboy identity in Joan Anim-Addo's collection of poetry Janie, Cricketing Lady, written as a tribute to her mother Jane Joseph, and Margaret Cezair-Thompson's novel The Pirate's Daughter, a fiction about Errol Flynn's ‘outside’ Jamaican daughter, May. It will argue that the ongoing affects of colonialism and patriarchy in the islands of Grenada and Jamaica, respectively, shape the life narratives of Janie and May who express their anger, shame, fear, frustration and desire (...) through their ambiguous gender identity and through their determination to intervene in masculinist traditions, such as cricket, piracy and adventure, traditions that underpin Caribbean his/tories. To understand the way in which affect can be expressed through tomboyism in Caribbean societies, it is necessary to look at colour and class alongside gender in the context of Caribbean creolisation.

Generalized anxiety disorder (GAD) and social phobia (SP) are major anxiety disorders identified by the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV). They are comorbid, overlap in symptoms, yet present with distinct features (worry in GAD and fear of embarrassment in SP). Both have also been explained in terms of conditioning-based models. However, there is little reasoning currently to believe that GAD in adulthood reflects heightened conditionability or heightened threat processing—though patients with SP may show heightened processing (...) of social threat stimuli. Moreover, the computational architectures that maintain these disorders in adulthood are different. For GAD this may reflect the development of an inefficient “worrying” strategy of emotional regulation. For SP this appears to reflect the atypical processing of self-referential information.

Abstract:This paper offers a historico-political exegesis of V-I Mudimbe’s Invention of Africa and Idea of Africa, reading how these texts respond to a post-independence African context of political and epistemic despair. This despair reflects at once the desire for a non-Western claim to knowledge and life, for political and economic autonomy from the West, and the seeming impossibilities (confirmed by the political ordinary) of enacting these. Retracing Mudimbe’s analysis of African political thought in the wake of Négritude and his critique (...) of representation, this essay works through Mudimbe’s intellectual historical methods to draw out a subtextual response to questions of historicity, political commitment, and the role of intellectual thought in Black resistant response. I argue that these questions are instantiated in the concept of “absolute discourse.” This concept reveals a theory of speech, inhabitation, and contingency critically aligned with postcolonial Marxist demands for authenticity, sovereignty and authority. Moreover, through this, and against any presumption of futility, I argue that Mudimbe constitutes a theory of politics—of resistance, claim, and seizure, and their limits—and contingency amidst seeming and real epistemic and material closures.

This work promotes the thesis that humans are naturally transhuman. In order to achieve this, we present in the first two sections some examples of technological devices assembled to human beings, and we critically review the assumptions and dichotomies on which the idea of human enhancement is based according to the ordinary transhumanist vision. Thirdly, we present the thesis of the Extended Mind to support our intuition. Fourthly, we dismantle the most relevant philosophical dichotomies that structure the transhumanist position. Finally, (...) we recapitulate the reasons why we should wake up from the transhumanist dream. (shrink)

O presente trabalho tem como objetivo analisar o fenômeno do Totalitarismo no pensamento da filósofa alemã Hannah Arendt tendo como fio condutor a obra Origem do Totalitarismo. Verificaremos como a filósofa compreende o movimento totalitário e atuação do mesmo para capturar os seres humanos e destituí-los de todos os direitos usando para este fim os mais baixos artifícios, tais como os campos de concentração e o sistema propagandista ficcional. Focalizaremos especificamente no terceiro capítulo da obra supracitada, no qual a pensadora (...) apresenta os horrores das ditaduras e do Totalitarismo, revelando a face tenebrosa e cruel do homem.

The extended mind thesis maintains that the functional contributions of tools and artefacts can become so essential for our cognition that they can be constitutive parts of our minds. In other words, our tools can be on a par with our brains: our minds and cognitive processes can literally ‘extend’ into the tools. Several extended mind theorists have argued that this ‘extended’ view of the mind offers unique insights into how we understand, assess, and treat certain cognitive conditions. In this (...) chapter we suggest that using AI extenders, i.e., tightly coupled cognitive extenders that are imbued with machine learning and other ‘artificially intelligent’ tools, presents both new ethical challenges and opportunities for mental health. We focus on several mental health conditions that can develop differently by the use of AI extenders for people with cognitive disorders and then discuss some of the related opportunities and challenges.
