Este artigo visa analisar indícios verbo-visuais de episódios de mal-estar enunciados por alunos que integram turmas da modalidade Educação de Jovens Adultos (EJA) em uma escola do interior baiano. Dedicamo-nos, especialmente, a compreender como os sujeitos semiotizam situações de embaraço social vivenciadas em salas de aula e(m) seus (d)efeitos. Como referencial teórico, partimos de pressupostos da Análise Dialógica do Discurso, da Clínica da Atividade e de outras categorias discursivas para lermos, a partir de uma dimensão axiológica, o corpus que é (...) composto por duas biograficzines. A análise dos dados registra que os (res)sentimentos dos discentes, que se deixam materializar em termos verbo-visuais, deflagram situações que ilustram a complexidade de dinâmicas que perfazem interações didáticas no ambiente escolar. Trabalhos como o nosso contribuem para tensionar a realidade escolar-profissional possibilitando a exploração de outros ângulos de nossas atividades como sujeitos sociais. (shrink)

Este artigo visa analisar modos de axiologizar o bem-estar na escola em enunciados produzidos por alunos do 9º ano do ensino fundamental de uma escola municipal do interior baiano. Interessa-nos, especialmente, compreender como os sujeitos semiotizam, em seus enunciados, o que consideram o evento mais marcante de suas experiências ao longo dos anos finais do ensino fundamental e o que isso nos informa sobre os valores ali mobilizados relativos ao papel social e institucional da escola e(m) suas modalidades de convivência (...) intersubjetiva. As análises destacam que as memórias verbo-visualmente materializadas não se limitam a registros, abrigados na consciência, mas são repositórios de experiências afetivas de e em diversos cronotopos. O fato de as memórias apresentadas recobrirem diferentes eventos interacionais oferecem-nos uma visão crítica dos estudantes de como percebem e matizam complexidades das interações por eles rememoradas e enunciadas. Trabalhos, como o nosso, que se interessam pelos afetamentos de alunos, contribuem, localmente, para que o contexto escolar seja (re)(des)coberto, tensionando como percepções sociais são semiotizadas em horizontes apreciativos de experiências.

A current issue in psycholinguistic research is whether the language difficulties exhibited by children with developmental language disorder [DLD, previously labeled specific language impairment ] are due to deficits in their abilities to pick up patterns in the sensory environment, an ability known as statistical learning, and the extent to which explicit learning mechanisms can be used to compensate for those deficits. Studies designed to test the compensatory role of explicit learning mechanisms in children with DLD are, however, scarce, and (...) the few conducted so far have led to inconsistent results. This work aimed to provide new insights into the role that explicit learning mechanisms might play on implicit learning deficits in children with DLD by resorting to a new approach. This approach involved not only the collection of event-related potentials, while preschool children with DLD [relative to typical language developmental controls] were exposed to a continuous auditory stream made of the repetition of three-syllable nonsense words but, importantly, the collection of ERPs when the same children performed analogous versions of the same auditory SL task first under incidental and afterward under intentional conditions. In each of these tasks, the level of predictability of the three-syllable nonsense words embedded in the speech streams was also manipulated to mimic natural languages closely. At the end of both tasks’ exposure phase, children performed a two-alternative forced-choice task from which behavioral evidence of SL was obtained. Results from the 2-AFC tasks failed to show reliable signs of SL in both groups of children. The ERPs data showed, however, significant modulations in the N100 and N400 components, taken as neural signatures of word segmentation in the brain, even though a detailed analysis of the neural responses revealed that only children from the TLD group seem to have taken advantage of the previous knowledge to enhance SL functioning. These results suggest that children with DLD showed deficits both in implicit and explicit learning mechanisms, casting doubts on the efficiency of the interventions relying on explicit instructions to help children with DLD to overcome their language difficulties.

Este livro apresenta Comte e seu Positivismo em linguagem clara e despretensiosa, pois é de alguém que conhece o que está escrevendo. A vida, a obra, a religião, a difusão e a irradiação do Positivismo no RS e no Brasil, e mais a educação e arte positivista em Porto Alegre são temas desenvolvidos com maestria por Mozart Pereira Soares.

Like Einstein's general theory of relativity is concerned with explaining the basics of an observable experience – i.e., gravity – most people take for granted that Chomsky's theory of generative grammar (GG) is concerned with the basic nature of language. This chapter highlights a mere subset of central constructs in GG, showing how they have featured prominently and thus shaped formal linguistic studies in multilingualism. Because multilingualism includes a wide range of nonmonolingual populations, the constructs are divided across child bilingualism (...) and adult third language for greater coverage. In the case of the former, the chapter examines how poverty of the stimulus has been investigated. Using the nascent field of L3/Ln acquisition as the backdrop, it discusses how the GG constructs of I‐language versus E‐language sit at the core of debates regarding the very notion of what linguistic transfer and mental representations should be taken to be.

The use of robots had already been proven to encourage the promotion of social interaction and skills lacking in children with Autism Spectrum Disorders, who typically have difficulties in recognizing facial expressions and emotions. The main goal of this research is to study the influence of a humanoid robot to develop socio-emotional skills in children with ASD. The children’s performance in game scenarios aiming to develop facial expressions recognition skills is presented. Along the sessions, children who performed the game scenarios (...) with the robot and the experimenter had a significantly better performance than the children who performed the game scenarios without the robot. The main conclusions of this research support that a humanoid robot is a useful tool to develop socio-emotional skills in the intervention of children with ASD, due to the engagement and positive learning outcome observed.

The present study uses EEG time-frequency representations with a Flanker task to investigate if and how individual differences in bilingual language experience modulate neurocognitive outcomes in two bilingual group types: late bilinguals and early bilinguals. TFRs were computed for both incongruent and congruent trials. The difference between the two was then compared between the HSs and the L2 learners, modeled as a function of individual differences with bilingual experience within each group separately and probed for its potential symmetry between brain (...) and behavioral data. We found no differences at the behavioral and neural levels for the between-groups comparisons. However, oscillatory dynamics of inhibition and cognitive control were found to be modulated by individual differences in bilingual language experience, albeit distinctly within each bilingual group. While the results indicate adaptations toward differential brain recruitment in line with bilingual language experience variation overall, this does not manifest uniformly. Rather, earlier versus later onset to bilingualism—the bilingual type—seems to constitute an independent qualifier to how individual differences play out. (shrink)

ENTRE A FILOSOFIA ANALÍTICA E O CULTURALISMO JURÍDICO: A APROXIMAÇÃO DO PENSAMENTO JUSFILOSÓFICO DE NORBERTO BOBBIO COM O DE MIGUEL REALE.

Trata-se de apontar neste artigo que em Heidegger há dois caminhos diferentes para se investigar a questão do niilismo, que não são necessariamente excludentes, mas que por se localizarem em pontos diferentes em relação à sua virada (Kehre) de pensamento, acaba sempre gerando o questionamento de se estamos frente ao mesmo projeto ou não. Procuraremos demarcar a discussão e mostrar que seja tomada como uma empreitada de longo prazo ou não, o niilismo enquanto relacionado ao nada, na visão dos filósofos (...) da Escola de Kyoto, em especial Nishitani, não pode ser superado. Por consequência, passamos a investigação da proposta de superação do niilismo e buscamos os antecessores de sua discussão sobre a Vacuidade em Nagarjuna. (shrink)

parte 1. As ideologias no século XXI -- parte 2. Ideologias, ambiente(s), identidade(s).

Pretende-se mostrar, a partir do pensamento de Keiji Nishitani, os pressupostos para a discussão sobre o “vazio-saber” e que passa pela questão do niilismo e da vacuidade em sua filosofia. O problema do niilismo em Nishitani, diferente da perspectiva adotada pelos filósofos ocidentais, não está ligada à ideia de que o Eu frente ao Nada perde seus fundamentos e sua existência, deixando de ter sentido. Pelo contrário, é no encontro com o Nada que o homem pode descobrir e entrar em (...) contato com sua verdadeira essência, uma vez que, é nesse encontro que sua existência se revela. Isso só seria possível caso o Eu realizasse um processo de auto abertura, um salto para dentro da Vacuidade, para que aí sua verdadeira face se revele e ele possa encontrar seu verdadeiro ser. Pretende-se desenvolver esses desdobramentos ao longo do artigo. (shrink)

The text examines the article 11 of the Universal Declaration on Bioethics and Human Rights of UNESCO that deals with the principle of non-discrimination and non-stigmatization. Both concepts are related to the theme of human dignity, while discrimination is an inherent part of stigma: stigma does not exist if there is no discrimination. In this context, this paper aims to study the relationship between stigma, discrimination and HIV / AIDS. The study argues that to loosen the bonds that hold the (...) subjects that are attached to them is necessary questioning the broader forces - social, cultural, political and economic - that structure stigma, stigmatization and discrimination as social processes directly linked to production and reproduction of structural inequalities.

This study aims to analyze the relationship between psychological capital profiles and internal learning in teams. The participants in this study were 480 undergraduate students. We performed a cluster analysis using the SPSS and yielded four distinct psychological capital profiles. The student profile with the highest scores in self-efficacy, optimism, hope, and resilience exhibited also the highest scores of internal learning in teams. On the other hand, the student profile with the lowest scores in self-efficacy, optimism, hope, and resilience presented (...) the lowest scores of internal learning in teams. It is also noteworthy that there was no significant relationship between the profile with a positive combination between self-efficacy and hope and the profile that presents the optimism as the only positive psychological capability, in the way they relate to internal learning in teams, which led us to reject the second hypothesis of the study. This study reinforces the role of psychological capital in academic settings and suggests that psychological capital profiles can affect internal learning in teams differentially. (shrink)

Ética y bioética en el mundo científico: una revisión integradora de la literaturaEthics and Bioethics in the Scientific World: An Integrative ReviewThis paper studies the reality of ethical and bioethical issues in the scientific world through an integrative literature review of articles included in three databases. Seven terms from the thesaurus Health Sciences Descriptors were used, from which three combinations were elaborated and used in the three databases. After applying inclusion requirements, a total of 18 articles were selected. Certain misconducts, (...) particularly plagiarism, falsification and data fabrication, have been showing an increasing behavior, which requires more stringent measures in order to control such phenomenon and maintain scientific credibility before society and authorities.Para citar este artículo / To reference this article / Para citar este artigoSouza-Júnior EV, Rosa RS, Guedes TP, Silva CS, Ribeiro DB, Balbinote FS, Souza DF, Teixeira RB, Silva-Filho BF, Sawanda NO.

As the world faces increasingly disparate challenges, science is being subjected to vehement demands from society calling for transparency, openness and public participation in science policy. This book provides a framework and a vision on how to conceive, discuss and evaluate the changes that occur in the relationship between science and society.

In this book, the author examines the ethical implications of Artificial Intelligence systems as they integrate and replace traditional social structures in new sociocognitive-technological environments. She discusses issues related to the integrity of researchers, technologists, and manufacturers as they design, construct, use, and manage artificially intelligent systems; formalisms for reasoning about moral decisions as part of the behavior of artificial autonomous systems such as agents and robots; and design methodologies for social agents based on societal, moral, and legal values. Throughout (...) the book the author discusses related work, conscious of both classical, philosophical treatments of ethical issues and the implications in modern, algorithmic systems, and she combines regular references and footnotes with suggestions for further reading. This short overview is suitable for undergraduate students, in both technical and non-technical courses, and for interested and concerned researchers, practitioners, and citizens. (shrink)

Contemporary theories of consciousness are based on widely different concepts of its nature, most or all of which probably embody aspects of the truth about it. Starting with a concept of consciousness indicated by the phrase “the feeling of what happens” (the title of a book by Antonio Damásio), we attempt to build a framework capable of supporting and resolving divergent views. We picture consciousness in terms of Reality experiencing itself from the perspective of cognitive agents. Each conscious experience is (...) regarded as composed of momentary feeling events that are combined by recognition and evaluation into extended conscious episodes that bind cognitive contents with a wide range of apparent durations (0.1 secs to 2 or more secs, for us humans, depending on circumstances and context). Three necessary conditions for the existence of consciousness are identified: a) a ground of Reality, envisaged as an universal field of potentiality encompassing all possible manifestations, whether material or 'mental'; b) a transitional zone, leading to; c) a manifest world with its fundamental divisions into material, 'informational' and quale-endowed aspects. We explore ideas about the nature of these necessary conditions, how they may relate to one another and whether our suggestions have empirical implications. (shrink)

This paper proposes a classification of economic models into three types: historical, axiomatic and conditional. Historical or empirical models utilize the historical-deductive method, and are generalizations from the economic regularities and tendencies that we find in the real world. Axiomatic models utilize the hypothetical-deductive method; they are syllogisms whose major premise is an axiom – a self-evident truth; they are appropriate for methodological sciences such as mathematics and econometrics. Conditional economic models are likewise syllogisms, but they are suitable for economics (...) because they make for clearer and more precise economic reasoning. The criterion of truth of the substantive sciences is the conformity with reality, of the methodological science, its internal consistency. When a school of economic thought adopts mainly axiomatic models, as is the case with neoclassical economics, it implicitly falls into contradiction because their best representatives believe in the conformity with reality criterion.

Virginia Held assesses the ethics of care as a promising alternative to the familiar moral theories that serve so inadequately to guide our lives. The ethics of care is only a few decades old, yet it is by now a distinct moral theory or normative approach to the problems we face. It is relevant to global and political matters as well as to the personal relations that can most clearly exemplify care. This book clarifies just what the ethics of care (...) is: what its characteristics are, what it holds, and what it enables us to do. It discusses the feminist roots of this moral approach and why the ethics of care can be a morality with universal appeal. Held examines what we mean by "care," and what a caring person is like. Where other moral theories demand impartiality above all, the ethics of care understands the moral import of our ties to our families and groups. It evaluates such ties, focusing on caring relations rather than simply on the virtues of individuals. The book proposes how such values as justice, equality, and individual rights can "fit together" with such values as care, trust, mutual consideration, and solidarity. In the second part of the book, Held examines the potential of the ethics of care for dealing with social issues. She shows how the ethics of care is more promising than Kantian moral theory and utilitarianism for advice on how expansive, or not, markets should be, and on when other values than market ones should prevail. She connects the ethics of care with the rising interest in civil society, and considers the limits appropriate for the language of rights. Finally, she shows the promise of the ethics of care for dealing with global problems and seeing anew the outlines of international civility. (shrink)

Objective:To describe the professional values of the nurse lectures according to 241 nursing students, who participated voluntarily, in three different universities of Bogotá.Methodology:This is a quantitative, descriptive cross-sectional study that applied the Nurses Professional Values Scale—permission secured—Spanish; three dimensions of values were applied: ethics, commitment, and professional knowledge.Ethical consideration:Project had ethical review and approval from an ethics committee and participants were given information sheets to read before they agreed to participate in the project.Findings:It was concluded that nursing students, in general, (...) do perceive these values in their professors, and they give priority to the dimension of ethics, followed by the knowledge dimension, and finally, commitment.Discussion:It is evident that professional values are transmitted by professors and students place importance to such values. Values related to the other’s care are paramount in nursing training in Colombia as well as in other countries.Conclusion:It was found that participating students observed professors directly in relation to values focused on direct patient care, respect for privacy, respect for life, while matters related to professional improvement, participation in unions were not actually analyzed may be due to poor promotion activities and unions during undergraduate studies. The results obtained are primary approach to the study of values related to nursing, a topic which needs to be researched, something vital to all the country offering nursing training programs.

Resumen El uso del término imaginación remite a un cierto tipo de actividad mental que en su formulación más básica refiere a la capacidad humana para crear imágenes en ausencia de lo representado, es decir, para representarnos objetos o estados de cosas que están ausentes, y a la capacidad para crear imágenes a partir de otras que ya se poseen. Esta formulación permite dar cuenta de una amplia gama de experiencias humanas que van desde la creación artística y la innovación (...) técnica hasta la anticipación de posibles escenarios en los que intervenir. En particular voy a centrarme en un uso específico de la imaginación que denominaré imaginación práctica y que consiste principalmente en la anticipación contrafáctica de posibles estados de cosas resultantes de nuestras acciones. A partir de esto sostendré la existencia de una relación interna entre imaginación práctica y racionalidad práctica, en virtud de la cual la primera oficia de posibilitadora de la segunda. Para ello relevaré cuatro formas de ejercicio de la racionalidad práctica que han sido tematizadas a lo largo de la historia de la filosofía: la ética, la moral, la política y la legal.The use of the term imagination refers to a certain type of mental activity that in its most basic formulation refers to the human capacity to create images in the absence of what is represented, that is, to represent objects or states of things that are absent, and the ability to create images from others that are already possessed by the agent. This formulation allows to account for a wide range of human experiences ranging from artistic creation and technical innovation to the anticipation of possible scenarios in which to intervene. In particular, I will focus on a specific use of the imagination that I will call practical imagination and that consists mainly in the counterfactual anticipation of possible states of affairs resulting from our actions. From this perspective I will sustain the existence of an internal relation between practical imagination and practical rationality, by virtue of which the first enables the second. To do this, I will highlight four types of practical rationality that have been thematized throughout the history of philosophy: ethical, moral, political and legal rationality. (shrink)

How is feminism changing the way women and men think, feel, and act? Virginia Held explores how feminist theory is changing contemporary views of moral choice. She proposes a comprehensive philosophy of feminist ethics, arguing persuasively for reconceptualizations of the self of relations between the self and others and of images of birth and death, nurturing and violence. Held shows how social, political, and cultural institutions have traditionally been founded upon masculine ideals of morality. She then identifies a distinct feminist (...) morality that moves beyond culturally embedded notions about motherhood and female emotionality. Examining the effects of this alternative moral and ethical system on changing social values, Held discusses its far-reaching implications for altering standards of freedom, democracy, equality, and personal development. Ultimately, she concludes, the culture of feminism could provide a fresh perspective on--even solutions to--contemporary social problems. Feminist Morality makes a vital contribution to the ongoing debate in feminist theory on the importance of motherhood. For philosophers and other readers outside feminist theory, it offers a feminist moral and social critique in clear and accessible terms. (shrink)

Este estudio se ocupa del control social del cuerpo y de la reconfiguración de la memoria popular en películas de horror a través de la perspectiva genealógica de Foucault, presentada en su libro Vigilar y Castigar, publicado hace 40 años. Por lo tanto, tomaremos, À l’interieur e Frontière (s), dos producciones de horror cinematográfico hechas por directores franceses, ambos publicados en 2007. La hipótesis principal es que las películas de terror se muestran como una nueva forma de vigilancia y control (...) social del cuerpo. Por otro lado, también puede recodificar la memoria popular apropiándose de acontecimientos polítcos y/o revolucionarios como en las películas comentadas por Foucault en la revista Cahiers de Cinéma en 1974 políticas, aunque no sean las películas de terror.

There are many different forms and interpretations of rewilding: the concept and its practice vary from country to country, with distinct interpretations according to its geographical location. Despite the term rewilding having been present in the lexicon for three decades, the concept of rewilding in England has experienced a prolonged developmental stage. This paper argues that a unique form of English rewilding is now emerging, which is distinct from rewilding in other parts of the world. Compared to other locations rewilding (...) in England operates at smaller spatial scales; its ambitions to increase biodiversity, restore ecosystem functioning and increase natural autonomy are somewhat curtailed; it involves higher levels of human intervention; and, perhaps most tellingly of all, it goes by another name - 'wilding', 'wild' or 'wilder' with little mention of the much-maligned prefix 're'. This conclusion has been developed following a comparative case study of two English 'rewilding' sites (the Avalon Marshes and Wild Ennerdale) involving 49 semi-structured interviews: twelve expert interviews and nineteen and eighteen stakeholder/practitioner interviews at the Avalon Mashes and Wild Ennerdale respectively.

Nearly two hundred years ago, Mary Wollstonecraft wrote what is considered to be the first major work of feminist political theory: A Vindication of the Rights of Women . Much has been written about this work, and about Wollstonecraft as the intellectual pioneer of feminism, but the actual substance and coherence of her political thought have been virtually ignored. Virginia Sapiro here provides the first full-length treatment of Wollstonecraft's political theory. Drawing on all of Wollstonecraft's works and treating them thematically (...) rather than sequentially, Sapiro shows that Wollstonecraft's ideas about women's rights, feminism, and gender are elements of a broad and fully developed philosophy, one with significant implications for contemporary democratic and liberal theory. The issues raised speak to many current debates in theory, including those surrounding interpretation of the history of feminism, the relationship between liberalism and republicanism in the development of political philosophy, and the debate over the canon. For political scientists, most of whom know little about Wollstonecraft's thought, Sapiro's book is an excellent, nuanced introduction which will cause a reconsideration of her work and her significance both for her time and for today's concerns. For feminist scholars, Sapiro's book offers a rounded and unconventional analysis of Wollstonecraft's thought. Written with considerable charm and verve, this book will be the starting point for understanding this important writer for years to come. (shrink)

É bem conhecida a divergência entre as posições de Gottlob Frege e Bertrand Russell com relação ao tratamento semântico dado a sentenças contendo termos singulares indefinidos, ou seja, termos singulares sem referência ou com referência ambígua, tais como ‘Papai Noel’ ou ‘o atual rei da França’ ou ‘1/0 ’ ou ‘√4’ ou ‘o autor de Principia Mathematica’. Para Frege, as sentenças da linguagem natural que contêm termos indefinidos não formam declarações e portanto não são nem verdadeiras nem falsas. Já para (...) as sentenças da matemática, Frege defende que elas precisam ser corrigidas através da convenção forçada de uma referência não ambígua. Russell, por outro lado, aceita os termos indefinidos e propõe, através de sua teoria das descrições definidas, uma maneira de avaliar as sentenças em que eles ocorrem; e Quine amplia a teoria de Russell para abranger também os nomes com problemas de referência. Na prática da matemática são comuns os termos singulares indefinidos, sem referência, tais como ‘1/0 ’, ou com referência ambígua, tais como ‘√4’. Apesar de não haver uma sistematização rigorosa desta situação entre os matemáticos, há, no entanto, um conjunto de regras convencionais que tradicionalmente costumam ser aplicadas no tratamento matemático dos termos indefinidos. Nossa proposta é tomar a convenção matemática como inspiração e modelo para apresentar uma interpretação semântica formal para as descrições definidas e os nomes e utilizá-la como um argumento que favorece a abordagem de Russell relativamente à de Frege.
