People reject ‘paradoxical’ inferences, such as: Luisa didn't play music; therefore, if Luisa played soccer, then she didn't play music. For some theorists, they are invalid for everyday conditionals, but valid in logic. The theory of mental models implies that they are valid, but unacceptable because the conclusion refers to a possibility inconsistent with the premise. Hence, individuals should accept them if the conclusions refer only to possibilities consistent with the premises: Luisa didn't play soccer; therefore, if Luisa played a (...) game then she didn't play soccer. Two experiments corroborated this prediction for three sorts of ‘paradox’, including a disjunctive paradox. (shrink)

The multifaceted nature of empathy requires a comprehensive conceptualization of core and related emotional and mindreading processes. Here I argue that new paradigms are needed that allow for a more ecologically valid and parametric assessment of empathy subprocesses and their neuronal correlates. Towards that goal, cognitive neuroscience studies should make use of audiovisual stimuli that more closely approximate real-life settings and include online social interaction paradigms.

Marcuse teve no Brasil na década de 1970 uma recepção unilateral, sendo visto unicamente como guru da contra-cultura. Contra esse equívoco o artigo mostra a relação intrínseca entre teoria e prática na filosofia de Marcuse, caracterizada como uma filosofia política cuja preocupação central é a transformação radical da sociedade capitalista.

This paper gives an implicit characterization of the class of functions computable in polynomial space by deterministic Turing machines – PSPACE. It gives an inductive characterization of PSPACE with no ad-hoc initial functions and with only one recursion scheme. The main novelty of this characterization is the use of pointers to reach PSPACE. The presence of the pointers in the recursion on notation scheme is the main difference between this characterization of PSPACE and the well-known Bellantoni-Cook characterization of the polytime (...) functions – PTIME.

Like many humans in the wake of genocide and war, most wildlife today has sustained trauma. High rates of mortality, habitat destruction, and social breakdown precipitated by human actions are unprecedented in history. Elephants are one of many species dramatically affected by violence. Although elephant communities have processes, rituals, and social structures for responding to trauma—grieving, mourning, and socialization—the scale, nature, and magnitude of human violence have disrupted their ability to use these practices. Absent the cultural, carrier groups who traditionally (...) lead and teach these healing practices, humans must assume the role. Trauma theory has brought attention to victims' severe, sustained psychological damage. Looking through the lens of trauma theory provides a better understanding of how systematic violence has affected individuals and groups and how the pervasive nature of traumatic events affects human-nonhuman animal relationships. The framing of recent trauma theory compels conservationists to create new relationships—neither anthropocentric nor powerbased—with nonhuman animals. The David Sheldrick Wildlife Trust, Kenya, shows how humans, taking on the role of interspecies witness, bring orphan elephants back to health and help re-build elephant communities shattered by genocide.

A two-sorted term system characterizing NC implicitly is described. The term system is defined over the tree algebra [MATHEMATICAL DOUBLE-STRUCK CAPITAL T], the free algebra generated by 0, 1 and ∗, and the recursion scheme uses pointers over tier 0. This differs from previous characterizations of NC, where tier 1 pointers were used or full parameter substitution over tier 0 was allowed.

A partir da constatação de problemas no desempenho leitor de universitários, projeto de pesquisa realizado na Universidade de Caxias do Sul buscou oportunizar aos alunos o desenvolvimento de habilidades de leitura pelo uso de material instrucional composto por sequências didáticas baseadas em diferentes gêneros do discurso. Descrevemos aqui a sequência que tem como núcleo o editorial. Os alunos envolvidos, ingressantes em cursos de graduação, foram divididos em grupo experimental (GE), submetido à sequência de leitura aqui descrita, e grupo de controle (...) (GC), que trabalhou os mesmos textos do GE com enfoque voltado à análise textual. A questão ecológica constituiu o núcleo temático, e, em cada sequência, propuseram-se quatro instâncias: pré-leitura, leitura-descoberta, pós-leitura e atividade interativa. Os resultados da investigação sugerem que o ensino explícito de leitura, apoiado em princípios sociointeracionistas e metacognitivos, pode contribuir positivamente para o desenvolvimento de habilidades de leitura.

In this article, we examine the role of several consumers’ cognitive and psychographic traits in their perceptions of retailers’ deceptive practices and the different effects on perceived deception associated with online vis-à-vis in-store shopping. Building on theoretical models of persuasion in consumer behavior, we hypothesize that the antecedents of perceived deception in traditional settings are the same as those on the Internet, while the intensity of the impact of these antecedents differs between the online and the offline environment. Results suggest (...) that the effects of individual’s cognitive traits and risk aversion on perceived deception are more relevant when consumers shop online than when they purchase from traditional stores. Conversely, psychographic traits play a more important role in explaining perceived deception in the traditional shopping context as compared to the online channel. Several theoretical and managerial implications are derived from these findings. (shrink)

Coletânea de trabalhos de especialistas brasileiros que analisam algumas das obras mais importantes de pensadores marxistas deste século: O espírito da utopia (Bloch), Teoria do agir comunicativo (Habermas), Dialética negativa (Adorno), História e consciência de classe (Lukács), Contrarrevolução e revolta (Marcuse), Eduard Fuchs, o colecionador e o historiador (Walter Benjamin), As ideias fora do lugar (Roberto Schwarz), Marx: Lógica e política (Ruy Fausto) e Trabalho e reflexão (José Arthur Giannotti).

Rosa Luxemburg's interpretation of Marxism as the unity between theory and practice sets the basis of her "theory of revolutionary action". That expression can be said to encapsulate her political thought, which was developed in an uninterrupted polemic with the economicist determinism of the Second International.Ao interpretar o marxismo como unidade entre teoria e prática, Rosa Luxemburg lança os fundamentos da sua "teoria da ação revolucionária", palavras com que poderíamos sintetizar o seu pensamento político, elaborado numa polêmica ininterrupta com o (...) determinismo economicista da II Internacional.

El texto que proponemos tratará de destacar el papel que desempeña la religión en la obra más naturalista de Zola, esto es en Les Rougon-Macquart. Pero, ¿por qué elegir esta obra y no sus novelas posteriores donde el elemento religioso es mucho más evidente? Nuestra intención es desmentir el tradicional calificativo de anticlerical y de enemigo de la religión que soportó Zola hasta bien entrado el siglo XX. En efecto, sus libros esconden todo un universo religioso demasiado complejo, sutil y (...) recurrente como para ser considerado simplemente como anticlerical. Muy al contrario, atribuimos a la religión una importancia decisiva en el universo poético zoliano, en su arquitectura narrativa y en la ontología subyacente. Queremos, pues, contribuir al descubrimiento del verdadero alcance del tema religioso en Zola, fuera ya de las perspectivas sociológicas o ideológicas desde las que más comúnmente se ha tratado.

Summary This paper discusses the emergence of new medical experimental specialties at the Medical School of Surgery (Escola Médico-Cirúrgica) and the Faculty of Medicine of Lisbon University (Faculdade de Medicina da Universidade de Lisboa) between 1897 and 1946, as a result of the activities of Marck Athias's (1875?1946) histophysiology research school. In 1897, Marck Athias, a Portuguese physician who had graduated from the Faculty of Medicine in Paris, founded a research school in Lisbon along the lines of Michael Foster's physiology (...) research school in England and Franz Hofmeister's physiological chemistry school in Germany. His research programme was highly innovative in Portugal. Not only did it bring together many disciples and co-workers, but it branched out and created new medical specialties within Portuguese medical science. These new disciplinary areas grew out of the study of the histology of the nervous system but eventually expanded into normal and pathological histophysiology, physiological chemistry and experimental endocrinology. The esprit de corps that existed between research school members ensured the school's success and influence in various fields social and political as well as scientific. Athias's school was strongly influenced by positivist ideals and promoted a teaching and research style that sought inspiration in Humboldt's university model, thus helping to bring about a change in the dominant scientific ethos and to modernize scientific research in Portugal during the first half of the twentieth century.

Number is known for influencing time processing, but to what extent time influences number in human adults is unclear. We investigated possible bidirectional interactions using a novel Stroop-like task; participants compared numbers or temporal durations in congruent or incongruent conditions. Time and number tasks were presented in different blocks or within the same block of trials with task instructions provided at the offset of the stimuli. Analyses of response times and their distribution revealed that number affected time from early RTs, (...) and time affected number at late RTs – an asymmetry observed only when time and number tasks were presented in separate blocks. Thus, carefully chosen tasks and appropriate data analysis can reveal bidirectionality between time and number, consistent with shared magnitude or decision mechanisms. (shrink)

En este artículo se analiza la transexualidad y la intersexualidad como dos fenómenos que desafían las concepciones dimórficas de la anatomía corporal, así como las concepciones binarias del sexo y del género. En este desafío de la norma cultural y médica, los sujetos transexuales e intersexuales construyen un lugar de resistencia, proponiendo, en un movimiento de autodesignación, la concepción de un nuevo sujeto transgenérico. Por último, se reseñan algunas cuestiones éticas vinculadas a los tratamientos médicos de la asignación de sexo (...) a los intersexuales y a la reasignación de los transexuales, relativas a la autonomía y dignidad de estos sujetos transgenéricos.

En este artículo se examina la común estrategia metódica de los estudios sobre la discapacidad y la crítica feminista, que sitúa la experiencia de la discapacidad en el contexto de los derechos y las exclusiones. Este modelo social de la discapacidad critica el modelo biomédico que concibe la discapacidad como anormalidad y patología, como error de un orden natural dado. Para deconstruir este sujeto naturalizado se analiza una de las representaciones históricas de la discapacidad: la figura del monstruo. Por último, (...) se propone la discapacidad como ocasión para pensar la vulnerabilidad esencial de todo sujeto. (shrink)

In this paper I examine the figure of the monster, in both its negative and positive aspects, such as the notion of biopolitics. As a negative figure, the monster would represent the dehumanized subject produced by exclusion mechanisms operating in destructive version of biopolitics, resulting in thanatopolitics, and in this sense provokes horror and abjection. Here I will use the analyses of the anthropological machine (Agamben), the device of the person (Esposito) and indefinite detention (Butler). As a positive figure, the (...) monster would represent the new subject trying to articulate productive versions of biopolitics, and is distinguished by its metamorphic and posthuman appearance, and in this sense would be subject and object of joy. Finally, as a project of affirmative biopolitics, I discuss Butler’s proposal of a new way of thinking about the political community that assumes the original vulnerability of the subject. (shrink)

Johan Grimonprez’s dial H-I-S-T-O-R-Y has been critically surveyed for its use of mass media: this film, a masterful feat of editing, appropriates found footage from television newscasts to examine the history of hijacking. My reading of this piece further analyzes Grimonprez’s use of appropriation, locating the image of the chimera featured in the film as a symbol of the method of montage that dial H-I-S-T-O-R-Y uses, and of the links that this work makes between violence, homelessness and art making. The (...) chimera stands for the artwork itself, for the latter’s rapid sequence of disparate images functions as a grafted body. As a figment of the imagination, the chimera also stands for the constructed nature of the news event, which the film assays. Furthermore, the eloquence of the chimera’s image bespeaks the body that has lost its home. In this film, hijackings are related to homelessness; Grimonprez implies that wellsprings of violence arise from radical histories of displacement. By way of the chimera, he also suggests that art can impact society only by hijacking the images of mass culture, thus relating art making to violence. (shrink)
