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)

While firms' engagement with Corporate Social Responsibility has been associated with positive performance impacts, little is known about the incorporation of the United Nations 2030 Agenda into business practices. Precisely, although the literature suggests that firms are pursuing the Sustainable Development Goals (SDGs), there are limited insights on their strategy to implement them in the context of developing countries. To address this gap, we conducted a comprehensive large-scale investigation of 2030 Agenda adoption by Brazilian companies. Accordingly, the analysis of our (...) multicase study reveals (1) variations on the business opportunities brought by the SDGs depending on the firm position in the value chain, (2) which SDGs and target stakeholders are addressed through corporate policies and practices, (3) the different ways firms embrace the SDGs to pursue ambidexterity. Our findings clarify how firms in the developing countries interpret the institutional pressures and assemble their internal resources to respond to the SDGs challenges. Boundary conditions and policy implications are further discussed. (shrink)

Ao longo da história, a relação entre a filosofia e a política tem-se revelado espinhosa, denunciando a dificuldade em se conceptualizar sobre o que é por natureza antagónico à cristalização, porque particular e pluralista. Na esfera da opinião, o filósofo deve restringir-se a analisar, criticar, rever e aperfeiçoar os valores políticos coevos, a explicar aos seus conterrâneos o universo de acepções sociais partilhadas, consciente de que a sua concepção fundamenta uma via entre as muitas poss...

Publicada no ano de 1896, num contexto político adverso à propaganda anarquista – considerada como um crime pela Lei de 13 de Fevereiro desse mesmo ano –, esta obra revela os contornos doutrinários e históricos do anarquismo, sobretudo da feição dominante na militância anarquista em Portugal, o “anarquismo social”. Como assinala João Freire em “Revistas anarquistas portuguesas: entre a política e a cultura” (in Revistas, Ideias e Doutrinas, 2003), “o anarquismo social era certamente um social...

: As relações que Wittgenstein mantém com o pensamento de Freud,como atestaram vários estudiosos, são marcadamente ambíguas: existe, por um lado, uma crítica acerba do caráter pseudocientífico com que a psicanálise apresenta supostas “descobertas empíricas”, e do fascínio exercido por este modo de proceder; mas há, por outro lado, evidências da sua admiração pelo efeito dissolvente do uso de metáforas e interpretações, chegando mesmo Wittgenstein a incorporar essa estratégia ao seu próprio método de investigação lógica dos conceitos filosóficos. Neste trabalho (...) pretendo retirar de uma reflexão acerca do método incorporado às Investigações Filosóficas, comparável em muitos aspectos à clínica de uma psicanálise lingüística dessubstancializada, alguns pontos positivos que se poderiam acrescentar à crítica da concepção de linguagem de Lacan.

This paper explores Kant’s ambivalent views on music. It aims to show, on the one hand, how these ambivalences are in line with the modern philosophical reflection on this art; on the other hand, to show their place within Kantian aesthetics, a place that justifies Kant’s hesitations as whether to classify music as beautiful or agreeable, art or mere enjoyment, free or dependent beauty, culture or nature.

O presente estudo propõe-se questionar a alegada musicofobia de Kant comparando-a com a bem conhecida musicofilia de Nietzsche. A partir da análise das considerações, à primeira vista tão díspares, de ambos os filósofos sobre a música, procurar-se-á mostrar que tal disparidade é apenas aparente, pois, quer para Kant, quer para Nietzsche, a experiência de ouvir música relaciona-se de modo profundo com a experiência de pensar. This paper aims to question Kant's alleged musicophobia by comparing it with Nietzsche's well-known musicophilia. By (...) analysing the considerations of both philosophers about music, it will try to show that their opposition is only apparent inasmuch as, both for Kant as well as for Nietzsche, the experience of listening to music has deep affinities with the experience of thinking.

Ortega y Gasset enriqueceu os seus estudos na Alemanha entre 1905 e 1908, nas cidades de Leipzig, Berlim e Marburgo, tendo sido aqui discípulo do neokantiano HermannCohen. Tomando essa circunstância como ponto de partida, propõe-se, neste artigo,levar a cabo uma indagação sobre as ideias estéticas de Ortega, contrastando com os fundamentos das fontes kantianas ou neokantianas da sua formação universitária alemã,traçar uma linha que permita demarcar claramente até onde Ortega segue Kant e onde,pelo contrário, o filósofo espanhol trilha o seu (...) solitário e original caminho. Tomam-se como baluartes desta análise os quatro momentos do juízo de gosto inerentes à terceira crítica kantiana e a questão da genialidade. (shrink)

Nietzsche's metaphor of the spider that spins its cobweb expresses his critique of the metaphysical use of language - but it also suggests that ‟we, spiders‟, are able to spin different, life-affirming, healthier, non-metaphysical cobwebs. This book is a collection of 12 essays that focus not only on Nietzsche's critique of the metaphysical assumptions of language, but also on his effort to use language in a different way, i.e., to create a ‟new language‟. It is from this viewpoint that the (...) book considers such themes as consciousness, the self, metaphor, instinct, affectivity, style, morality, truth, and knowledge. The authors invited to contribute to this volume are Nietzsche scholars who belong to some of the most important research centers of the European Nietzsche-Research: Centro Colli-Montinari (Italy), GIRN (Europhilosphie), SEDEN (Spain), Greifswald Research Group (Germany), NIL (Portugal). In 2011 João Constâncio and Maria João Mayer Branco edited Nietzsche on Instinct and Language, also published by Walter de Gruyter. The two books complement each other. (shrink)

It will never be too much to remember that experience is one of the most important concepts on Benjamin’s thought. It underlies his analysis of the history and also supports his critical theory of literature and has many branches, above all in his texts after 1930. His text “The Image of Proust” develops the concept of involuntary memory, which explains the question of auratic image in the work of Proust, obtained by the process of rememoration and also explained by the (...) contribution of Freud’s studies about the traumatic shock and its consequences on the perception’s conditions of the contemporary man. These conceptions led Benjamin to a deep thought about the way how shock and rememoration can be articulated in order to create a new historical vision, individual and collective. We examine here, in the fields of the arts, literature and history, how this articulation can defines a new conception of experience and the possibility, or not, of the transmission of the culture, in a world where, as Kafka said, “the tradition became sick”. The question is: will rememoration, this Penelope’s web, be able to operate the rescue of the historical tradition? And which tradition are we speaking here about? What does rememoration mean?

Na sua obra Spectres de Marx, Derrida parte da análise da tese II da obra de Benjamin, Über den Begriff der Geschichte, onde o autor fala do índex messiânico que cabe ao historiador redescobrir e restaurar. Benjamin não se refere a este messianismo em termos teológicos nem tradicionais, mas pensa, a partir de uma ideia de secularização do messianismo, que contém um potencial inédito para a compreensão e leitura da história. Derrida segue-lhe o raciocínio e interpreta, de forma magnífica, em (...) que consiste este carácter de “messiânico sem messianis mo” e qual o seu significado no contexto de um pensamento político e revolucionário.

Uma das problemáticas essenciais do pensamento benjaminiano é, precisamente, a questão da história. Numa época em que a tonalidade dominante é a ameaça da guerra e a destruição das ideologias, dos valores e ideais clássicos, em nome de uma desenfreada visão progressista e continuista da história humana, é preciso despertar do pesadelo da catástrofe da história. É esta que é responsável pela dissolução do conceito de experiência, alienando o homem e deixando-o desamparado e entregue ao vazio da experiência do choque, (...) à fragmentação da narração e à perda da tradição. Recorrendo à tradição judaica da história, pensando e reconfigurando conceitos que lhe são intrínsecos, como o de catástrofe, messianismo, redenção, rememoração, Benjamin constrói uma teoria que possa operar uma desconstrução da continuidade da história, valorizando o objecto histórico, destacando-o do fluxo e salvando-o da catástrofe. Trata-se, assim, de um método destrutivo e violento, mas que visa restaurar uma visão da história que seja capaz de reparar as injustiças e o sofrimento humano. Mais do que histórica e temporal, essa nova ordem inscreve o sagrado na ordem profana, redimindo o acontecimento histórico e salvando-o no instante dialéctico. (shrink)

Palace of the End is a dense triptych of monologues exploring alternative narratives - albeit based in real facts - behind the events and the headlines surrounding the war in Iraq. Borrowing its title from the former royal palace where Saddam Hussein’s torture chamber was located, Thompson’s docudrama is structured as a chain of monologues telling three real-life stories set in the context of the war in Iraq. The play conveys three unconventional interpretations of the realities of war: that of (...) a young American soldier convicted for her misconduct at Abu Ghraib, the prison that stands as one of the most controversial symbols of the American-led Iraq invasion; a British scientist and weapons inspector who denounces what he understands as the false arguments given by his country’s leaders for engaging in a distant war; and an Iraqi mother whose life was shattered firstly by Saddam Hussein’s authoritarian regime, and later by the American first Gulf War. Each story is an enthralling and gut-wrenching reflection of one of the contemporary world’s most studied and controversial conflicts. The play gives voice to three different kinds of war victims, insofar as their political subjectivities and their moral conundrums are concerned. (shrink)

Na esteira da distinção entre «liberalismo» e «democracia», este artigo sonda a ideia de liber­dade do vintismo, tema privilegiado pelo magistério e ensaísmo de Zília Osório de Castro. Lan­çando o olhar sobre a governação vintista, procura-se responder às questões: «a ideia de Cons­tituição e a lei eleitoral são ou não expressão da liberdade?» e «a maioria vintista corresponde ou não a um ideal de liberdade?».

To identify how digital media are being used by community-led initiatives of the Centro Region of Portugal, and to identify the requirements that a digital platform for mediation between agents in the territory should have, two focus groups were conducted, involving six small-sized community-led initiatives and six larger-sized community-led initiatives. This article details the results of these focus groups, according to the following main categories: use of existing communication and mediation tools; the purpose of use of digital tools; type of (...) experiences prompted by digital tools and attributes and features desired in a digital platform to support community-led initiatives. The results show differences between the use and needs of digital tools by small- and larger-sized initiatives and offer interesting insights to prototype an innovative digital solution, to enhance the actions of community-led initiatives. A reference framework for digital mediation strategies and a mobile app prototype were developed, based on these surveys. The article contributes with an analytical view about the development of digital solutions, which aim to strengthen the relationship among agents of local communities and promote mediation mechanisms among all stakeholders in territorial-based innovation.

This article is a defense of a philosophy of psychoanalysis with no interference whatever in the autonomy of the analyzed discipline. To comply with this objective, the Wittgensteinian philosophical method and its related concepts of grammar, grammatical description, and therapy, are being proposed. Such therapeutical objects of comparison are then applied to a case of use of psychoanalytic concepts in a text from Lacan's Seminar XV , to show a practical example of the kind of philosophy that we favor.

Casual sexual relationships are frequent relationship experiences in young adulthood that provide opportunities for many to explore sexual relationships and to construct their sexual identity. Empirical research on casual sex is still lacking outside North-American countries, despite evidence pointing to the need to contextualize sexual interactions in their own sociocultural context. In order to better understand casual sexual relationships, these should be examined in with novel samples in other countries where a “hookup culture” as it is described in the North-American (...) university campus is apparently absent. Through a qualitative study, we explored what casual sexual relationships consist of according to the perceptions of Portuguese college students. The thematic analysis of eight focus group interviews resulted in the generation of six themes, three of which are presented here: What CSRs are, regarding features and types of CSRs, Why individuals engage in CSRs, focusing on positive and negative motivations, and What one gets from CSRs, focusing on positive and negative outcomes of CSRs. Our findings showed that Portuguese emerging adults are familiarized with CSRs, particularly with one-night stand, friends with benefits and “curte”/hookup. Sexual interactions associated with other CSRs, such as booty call or fuck buddies, were mentioned but rarely associated with a distinctive label and established characteristics. Participants described the CSRs in a partially overlapping manner presenting some areas of ambiguity, such as with regard to sexual exclusivity and still-unlabeled sexual interactions. CSRs are generally evaluated as positively motivated and mainly beneficial. This study adds to the literature around casual sexual relationships by exploring and describing CSRs in a different sociocultural context, as well as indicating directions for future research in order to better prepare and empower young adults in their sexual and relational trajectories.

Neste trabalho buscaremos refletir sobre o racismo no Brasil a partir de uma perspectiva decolonial. Para tanto, utilizaremos a teorização de Quijano acerca do processo de construção do conceito de raça. Segundo o autor, o racismo surgiu como uma ferramenta de colonização, propiciando a expropriação de terras e a escravização dos corpos. Não obstante, a diferenciação e hierarquização de raças permaneceu mesmo após terminado o período colonial. Objetivando visualizar a progressão dessa prática no Brasil, dividimos essa investigação em dois tópicos: (...) 1) estudo da análise de Quijano sobre a raça e 2) identificação das formas pelas quais o racismo se consolidou no país, apoiadas no ideal progressista. Palavras-chave: Raça. Progresso. Brasil. Aníbal Quijano. Colonialidade. (shrink)

Neste artigo pretende-se elucidar os contornos libertários do pensamento do escritor Ferreira de Castro, através de uma análise dos seus artigos publicados em A Batalha – Suplemento Literário e Ilustrado e na Renovação. Na esteira de uma breve apreciação biobibliográfica, em que se assinala o percurso jornalístico do escritor, sonda-se a sua demora em temáticas como a arte social e a injustiça social.

O modo como Robert Nozick (1939-2002) concebeu a filosofia – enquanto espaço de abertura a uma pluralidade de ideias – revela a inquietação de quem, contemplando a paisagem no topo de um escadote milenário, assumiu a inexistência de pontos fixos e, por isso, declinou antever a direcção da humanidade e do pensamento. Pensador versátil, cuja curiosidade sobre o desconhecido o impeliu aos mais variados territórios da reflexão (ética, política, epistemologia e filosofia da mente), reconheceu em S...

To address the topic of children’s online aggression, this article explores a subsample from the EU Kids Online dataset of 1404 children, aged 9–16, who reported having engaged in aggressive acts online in the previous year. Through a cluster analysis, respondents were classified into three groups. Findings emphasize the risk factors for aggression and how they relate to age-specific developmental tasks. Boys predominate, but the gender gap is not as wide as in offline contexts. For almost half of the children, (...) aggression goes hand in hand with victimization. All the clusters share high levels of emotional deprivation. A sense of lacking social support, from both adults and peers, becomes more relevant among those children with high and more problematic engagement in online aggression. Results confirm that online aggression must be considered within the complex and fluid offline–online continuum cutting across the social contexts in which children grow. (shrink)
