O conceito de liberdade em o ser e o nada de Jean-Paul Sartre

This dissertation aims to address the concept of freedom from the perspective of the French philosopher Jean-Paul Sartre with reference to the main work Being and Nothingness. After presenting the concept of freedom we will try to show that it is related to the notion of responsibility, which will lead, ultimately, to define the Sartrean philosophy as a philosophy of action. In the first chapter we will present in passing the phenomenology of Edmund Husserl, philosopher from which Sartre will develop his concept of freedom. The Husserlian notion of consciousness (intentionality) is the way to develop his analysis of Sartre phenomenon of being. From this analysis Sartre submits their concepts of being in-itself and being for-itself. Being initself is defined as the things of the world devoid of consciousness, are the things that surround us. The In-itself has as its main brand positivity: it is what it is, is all that can be said about him. In turn being For-itself is the very being of man, which differs radically from the In-itself. The For-itself has as its main intentionality, ie, its ability to project outside itself in existence. That's when Sartre shows that this type of being realizes its existence on the basis of a constant nihilation. Here comes the notion of anything. Among the relations of the For-itself with the surrounding world stands a very special: relationship between consciousnesses. It is when we discuss the issue of another. Intersubjectivity, through sartrean analysis of look, show that the For-itself assumes a new existential dimension: the being-for others. That's when Sartre will emphasize his notion of conflict. The conflict in intersubjectivity would come from the fact that you want to take another- For-itself as an object. Given this we will analyze what Sartre called the concrete relations with others. The philosopher submit such relations in the form of ducts and conduits assimilation of ownership. In the first my-self to try to "get lost" in the consciousness of another, ownership of my conduct in-itself tries to "take ownership" of the subjectivity of the other and try to treat others as things, as objects. In this sense Sartre examines the experiences of love, masochism, indifference, desire and sadism. Following this route we will enter the land of freedom itself, which is the major theme of our work. Since Sartre defines the For-itself as a being that is projected to create your way of being, it can only define it as freedom. The freedom of the For-itself is taken in terms of autonomy of choice. Once the For-itself has no way of being a thing as being in-itself, it just may be picking up, that is, making your being. Here Sartre speaks of the anguish that would be the symptom of freedom itself. The fact that the For-itself have to choose on whether the call as one being distressed. However, in most cases the For-itself tries to escape from the anguish of freedom and takes refuge in bad faith. After setting the man (For-itself) as freedom Sartre defends that he is totally responsible for what he does of himself. Once the philosopher holds that man is not predetermined, ie, does not have an a priori essence, his philosophy has as its basic assumption the action. If Sartre argues that the For-itself must constantly choose your way of being, the action is the basis on which man will exercise his own freedom. In this sense we conclude the work with an approach to work Existentialism is a Humanism, which represent the entry of the philosopher on the practical aspects of life

Investigações em torno do antropocentrismo e da atual crise ecológica

Many environmental ethics thinkers bear the existing ecological crisis is resultig from the fact that both, our thoughts and our actions would be antropocentric. It means that they (our thoughts and our actions) would have the human needs and wishes satisfaction as their only goals. However, a careful investigation about the relationship among humans could perhaps unveil that we are not antropocentric yet. The aim of this work is to enlighten this: whether we think and act in an antropocentric way as it seems to be largely accepted. It seems that we have found a satisfatory answer to the question

Ulisses e Narciso: as faces da alma humana através do discurso mítico nas Enéadas de Plotino

This dissertation, witch studies the myth in Plotinus, attempts to set an approach to the comprehension of the mythic discourse as image related to the ethical process in the Enneads. In order to achieve it, the analysis of the mythic narrative will be employed in the philosophical context that has as a starting point a revisit of the platonic poetic conception. As central questions the notable mythological figures of Narcissus and Ulysses will be utilized to put into context the notion of the Plotinian soul and its endeavor of returning to the originary unity. Therefore, by following the course of both figures in their respective narratives, it conceives a possible relation of ascension and fall of the soul. The first part of this study intends to show Plato s interpretation on the myth and Plotinus standpoint in regard to it. Moreover, it observes Plato s criticism on poetry in the context of the Greek Paideia and the notion of the myth as image of the henological structure in Plotinus, who perceives in the myth its exemplifying nature. The second part attempts to structure Plotinus philosophy, contrasting Henology and Ontology, therefore exposing the three hypostases and the comprehension of the intelligible. The third part endeavors to display the sense of the myth, the idea of the myth as image in Plotinus and the roles of the mythical figures in the Enneads

Alterações da default mode network provocadas pela ingestão de Ayahuasca investigadas por Ressonância Magnética Funcional

Ayahuasca is psychotropic beverage that has been used for ages by indigenous populations in South America, notably in the Amazon region, for religious and medicinal purposes. The tea is obtained by the decoction of leaves from the Psychotria viridis with the bark and stalk of a shrub, the Banisteriopsis caapi. The first is rich in N-N-dimethyltryptamine (DMT), which has an important and well-known hallucinogenic effect due to its agonistic action in serotonin receptors, specifically 5-HT2A. On the other hand, β-carbolines present in B. caapi, particularly harmine and harmaline, are potent monoamine oxidase inhibitors (MAOi). In addition, the tetrahydroharmine (THH), also present in B. caapi, acts as mild selective serotonin reuptake inhibitor and a weak MAOi. This unique composition induces a number of affective, sensitive, perceptual and cognitive changes in individuals under the effect of Ayahuasca. On the other hand, there is growing interest in the Default Mode Network (DMN), which has been consistently observed in functional neuroimaging studies. The key components of this network include structures in the brain midline, as the anterior medial frontal cortex, ventral medial frontal cortex, posterior cingulate cortex, precuneus, and some regions within the inferior parietal lobe and middle temporal gyrus. It has been argued that DMN participate in tasks involving self-judgments, autobiographical memory retrieval, mental simulations, thinking in perspective, meditative states, and others. In general, these tasks require an internal focus of attention, hence the conclusion that the DMN is associated with introspective mental activity. Therefore, this study aimed to evaluate by functional magnetic resonance imaging (fMRI) changes in DMN caused via the ingestion of Ayahuasca by 10 healthy subjects while submitted to two fMRI protocols: a verbal fluency task and a resting state acquisition. In general, it was observed that Ayahuasca causes a reduction in the fMRI signal in central nodes of DMN, such as the anterior cingulate cortex, the medial prefrontal cortex, the posterior cingulate cortex, precuneus and inferior parietal lobe. Furthermore, changes in connectivity patterns of the DMN were observed, especially a decrease in the functional connectivity of the precuneus. Together, these findings indicate an association between the altered state of consciousness experienced by individuals under the effect of Ayahuasca, and changes in the stream of spontaneous thoughts leading to an increased introspective mental activity

O tratamento odontológico sob o olhar da criança :um estudo de representações sociais

Oral health measures directed to children are characterized by the lack of policies that consider the individual and his biopsychosocial aspects. As a consequence, it can be observed that a child´s dental experience has normally been prejudged as unpleasant and threatening. Thus, this study is aimed at investigating dental treatment from the child´s viewpoint using the theory of social representations for theoretical/methodological support. This theory was selected for being able to build practical knowledge surrounding the interrelations between social actors, the phenomenon and the world around them. The investigation was performed at the Professor José Fernandes Machado State School, located in the Ponta Negra district of Natal-RN-Brazil. The participants consisted of 30 children from the public elementary school system in the 6-10 year age group, who had undergone dental treatment within the previous year or were being treated at the time of data collection. An in-depth interview and story drawing within a theme were used as collection instruments. Thematic Content Analysis (Bardin, 2002) was used to analyze the material collected in the interviews, whereas for story drawing within a theme, in addition to content analysis, the data were also analyzed by the Coutinho model (2001). The two instruments demonstrated similarity of content as well as complementarity and contained categories associated to the model for dental treatment in children, the description of the dental office environment., the perception of the image of the dentist, as well as psychological and behavioral manifestations. The results enable us to understand determinate reactions of the children in relation to dental treatment, which has been characterized by its technical-curative approach, where the motive for seeking treatment, the manner in which it is performed and the relation of the dentist with the child are all in evidence. Thus, this study intends not only to reveal the viewpoint of children faced with dental treatment, but also to contribute to a dental practice directed towards them, in this way instilling in the professionals who attend them a more concrete awareness of the needs, anxieties and feelings of these young patients

Aspectos epidemiológicos, cognitivo-comportamentais e neurofisiológicos do sonho lúcido

Lucid dreaming (LD) is a mental state in which the subject is aware of being dreaming while dreaming. The prevalence of LD among Europeans, North Americans and Asians is quite variable (between 26 and 92%) (Stepansky et al., 1998; Schredl & Erlacher, 2011; Yu, 2008); in Latin Americans it is yet to be investigated. Furthermore, the neural bases of LD remain controversial. Different studies have observed that LD presents power increases in the alpha frequency band (Tyson et al., 1984), in beta oscillations recorded from the parietal cortex (Holzinger et al., 2006) and in gamma rhythm recorded from the frontal cortex (Voss et al., 2009), in comparison with non-lucid dreaming. In this thesis we report epidemiological and neurophysiological investigations of LD. To investigate the epidemiology of LD (Study 1), we developed an online questionnaire about dreams that was answered by 3,427 volunteers. In this sample, 56% were women, 24% were men and 20% did not inform their gender (the median age was 25 years). A total of 76.5% of the subjects reported recalling dreams at least once a week, and about two-thirds of them reported dreaming always in the first person, i.e. when the dreamer observes the dream from within itself, not as another dream character. Dream reports typically depicted actions (93.3%), known people (92.9%), sounds/voices (78.5%), and colored images (76.3%). The oneiric content was related to plans for upcoming days (37.8%), and memories of the previous day (13.8%). Nightmares were characterized by general anxiety/fear (65.5%), feeling of being chased (48.5%), and non-painful unpleasant sensations (47.6%). With regard to LD, 77.2% of the subjects reported having experienced LD at least once in their lifetime (44.9% reported up to 10 episodes ever). LD frequency was weakly correlated with dream recall frequency (r = 0.20, p <0.001) and was higher in men (χ2=10.2, p=0.001). The control of LD was rare (29.7%) and inversely correlated with LD duration (r=-0.38, p <0.001), which is usually short: to 48.5% of the subjects, LD takes less than 1 minute. LD occurrence is mainly associated with having sleep without a fixed time to wake up (38.3%), which increases the chance of having REM sleep (REMS). LD is also associated with stress (30.1%), which increases REMS transitions into wakefulness. Overall, the data suggest that dreams and nightmares can be evolutionarily understood as a simulation of the common situations that happen in life, and that are related to our social, psychological and biological integrity. The results also indicate that LD is a relatively common experience (but not recurrent), often elusive and difficult to control, suggesting that LD is an incomplete stationary stage (or phase transition) between REMS and wake state. Moreover, despite the variability of LD prevalence among North Americans, Europeans and Asians, our data from Latin Americans strengthens the notion that LD is a general phenomenon of the human species. To further investigate the neural bases of LD (Study 2), we performed sleep recordings of 32 non-frequent lucid dreamers (sample 1) and 6 frequent lucid dreamers (sample 2). In sample 1, we applied two cognitive-behavioral techniques to induce LD: presleep LD suggestion (n=8) and light pulses applied during REMS (n=8); in a control group we made no attempt to influence dreaming (n=16). The results indicate that it is quite difficult but still possible to induce LD, since we could induce LD in a single subject, using the suggestion technique. EEG signals from this one subject exhibited alpha (7-14 Hz) bursts prior to LD. These bursts were brief (about 3s), without significant change in muscle tone, and independent of the presence of rapid eye movements. No such bursts were observed in the remaining 31 subjects. In addition, LD exhibited significantly higher occipital alpha and right temporo-parietal gamma (30-50 Hz) power, in comparison with non-lucid REMS. In sample 2, LD presented increased frontal high-gamma (50-100 Hz) power on average, in comparison with non-lucid REMS; however, this was not consistent across all subjects, being a clear phenomenon in just one subject. We also observed that four of these volunteers showed an increase in alpha rhythm power over the occipital region, immediately before or during LD. Altogether, our preliminary results suggest that LD presents neurophysiological characteristics that make it different from both waking and the typical REMS. To the extent that the right temporo-parietal and frontal regions are related to the formation of selfconsciousness and body internal image, we suggest that an increased activity in these regions during sleep may be the neurobiological mechanism underlying LD. The alpha rhythm bursts, as well as the alpha power increase over the occipital region, may represent micro-arousals, which facilitate the contact of the brain during sleep with the external environment, favoring the occurrence of LD. This also strengthens the notion that LD is an intermediary state between sleep and wakefulness

Instrumentalidade do serviço social: dimensões teórico-metodológica, ético-política e técnico-operativa e exercício profissional

The dissertation proposes a discussion about the instrumentality of the Social Work, in the attempt of visualizing her, as well as the profession, in a totality perspective to the light of the rationality critical-dialetical. Understood as the capacity that the professional subjects acquire of giving answers to the demands that are placed to the profession, itself built partner-historically, in a teleologys conflicts and causalitys. So, it is proposed the discussion of the instrumentality while a group of you know specific, composed essentially by the development of three practical-formative dimensions. The theoretical-methodological refers to the capacity of apprehension of the method and of the theories and, consequently, of the relationship that does with the practice. The dimension ethical-politics concerns the development of the capacity of analyzing the society and the own profession as field of contradictory forces, being considered the character eminently political of the professional exercise, as well as the professional's conscience concerning the social direction that prints in your intervention. And the technician-operative dimension refers more strictly to the technical elements and you score for the development of the intervention. It was looked for to evidence as those dimensions they attend in the professional exercise, starting from the experience lived by the social workers of the Social Attendance Reference Centers, in Natal/RN

Ofensiva do Capital e Desmobilização das Forças do Trabalho: As Estratégias Gerenciais Burguesas para a Desarticulação das Classes Trabalhadoras

The problematic that gives shape to this research is the question of the historical process of demobilization of the movement of the working classes in your accented contemporary moment. Their object of study, however, and that it particularizes, it relates to a portion this problematic; it relates to set of determinations that comprise a broader set of determinations of this historical process: it is a set of determinations forged and mediated by bourgeois strategies of management for the conformation of the circumstances necessary for the domination and for the conduct of labor force on operations in work processes for the production of surplus value. What we investigated are, because, the strategies of disarticulation that the bourgeoisie utilizes, under the mantle of subsidies conceptual and interventive of its management of work processes and the sieve of class struggles, to obstruct the union of workers; hamper the movements proletarians. Managerial strategies that intentionally or unintentionally, instill in the social relations of production means to produce and reproduce, activate and reactivate conditions of incitement of individualism and competition between the workers themselves. We shall see, thus, by analyzing means, centrally, from some of the fundamentals of disarticulation in the managerial strategies bourgeois and some of the fundamental strategies of management bourgeois hegemonized with the restructuring productive of 1970, that the disarticulation, and also the demobilization, is a concrete condition, is an objective condition, that is beyond a question that can be "solved" only by enlightenment cognitive, only by formation criticism intellectual. In everyday of the work spaces permeated by managerial strategies bourgeois there elements, then, operating as a material force putting difficulties important for the articulation of the workers, the solidarity of the proletariat; elements that constitute obstacle significant to an awareness of class and belonging; elements act in favor of the atomization of the worker - even if engenders, in the same process, as a contradiction, potentiality of resistance and fight the forces of labor

Os caminhos da transição agroecológica: uma análise das experiências da agricultura familiar camponesa no território dos Vales do Curu e aracatiaçu-CE

This study examines peasant family farming from an agroecological perspective. It intends to analyze the changes resulting from the transition from conventional to agro-ecological agriculture in the daily practices of farmers articulated associated with the Network of Agroecological and Solidarity Farmers of the Curu and Aracatiaçu Valleys Territory, the locus of this empirical research, and a space which has highlighted the social dynamics of agroecological innovation, as well as articulating environmental exchanges and knowledge development. As a way to further that goal, we seek to identify the forms of social organization previously present in the daily lives of these subjects, in addition to grasping the determinants that lead or led them to adopt agroecology, noting the need to verify the forms of resistance, and the strategies adopted by farmers and how they articulate collectively. Through the historical and dialectical methods, we seek to take the implications of technical modernization of agriculture under the conditions of production and reproduction of peasants and thus situate the emergence of agroecology, a focus that is born as a counterpoint to conventional patterns of agricultural development based on the paradigm of the Green Revolution. We structured this study around the trajectory of agroecological farmers that developed and internalized agroecological practices, processes, and organizational forms. For the analysis, we used theoretical and methodological frameworks from literature related to field research. The systematization and analysis of experiments revealed that agroecological transition is a broad process of change, not restricted to technical matters. We observed changes in production practices, diversification of production and feeding practices, ecological awareness, production autonomy, and organizations formed to face the challenges resulting from the imposition of the dominant agricultural development model that combines environmental degradation, land ownership concentration, and wealth concentration

O grande experimento: sobre a oposição entre eticidade (Sittlichkeit) e autonomia em Nietzsche

Ayant comme but la notion nietzschéenne de moralité des moeurs (Sittlichkeit der Sitte), ce travail a l' intention de mettre en évidence la notion stratégique de la réflexion sur l' origine des valeurs morales dans la critique que Nietzsche fait à la métaphysique traditionnelle ainsi que le caractère spécifique de la contribution de ce philosophe pour le débat de ce thème.

Rosa Luxemburg: marxismo e história

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.

Relação entre habilidades auditivas e fonológicas em crianças com dislexia do desenvolvimento

A dislexia do desenvolvimento, dificuldade específica de leitura, é caracterizada pela dificuldade em realizar a decodificação fono-grafêmica e percepção de fonemas acusticamente semelhantes. Este estudo teve como objetivo caracterizar o desempenho de crianças com dislexia quanto às habilidades auditivas e de consciência fonológica, correlacionando-as. Participaram deste estudo crianças com dislexia e com bom desempenho escolar, submetidas a avaliações audiológica, do processamento auditivo e das habilidades fonológicas. Os resultados indicaram diferença estatisticamente significante entre as habilidades auditivas de seqüência para sons verbais, mensagem competitiva ipsi e contra-lateral, dicótico de dígitos e dissílabos alternados e ainda nos subtestes de síntese, segmentação, manipulação e transposição. Os achados deste estudo evidenciaram correlação entre provas de memória auditiva e manipulação silábica e fonêmica e associação entre habilidades auditivas e fonológicas, sugerindo que os processos auditivos interferem diretamente na percepção de aspectos acústicos, temporais e seqüenciais dos sons para formação de uma representação fonológica estável.

Desempenho escolar de crianças com Distúrbio Específico de Linguagem: relações com habilidades metafonológicas e memória de curto prazo

OBJETIVO: Descrever o desempenho de crianças com Distúrbio Específico de Linguagem (DEL) em provas de leitura, escrita, aritmética, consciência fonológica e memória seqüencial auditiva, assim como, verificar se há associação positiva entre as provas que avaliam a aprendizagem escolar e as que avaliam o processamento da informação. MÉTODOS: Vinte sujeitos com diagnóstico de DEL, com idades entre 7 e 12 anos, foram submetidos ao Teste de Desempenho Escolar (TDE) e a duas provas, que avaliam o processamento da informação (Perfil de Habilidades Fonológicas e Subteste de Memória Seqüencial Auditiva do Teste de Illinois de Habilidades Psicolingüísticas - ITPA). RESULTADOS: A maioria apresentou alteração em todas as provas realizadas. As associações entre o desempenho do grupo nas diferentes provas demonstram que a habilidade metafonológica apresentou associação estatisticamente significante com as habilidades de leitura (p=0,02) e escrita (p=0,02). Por sua vez, a habilidade de memória seqüencial auditiva apresentou associação estatisticamente significante apenas com a habilidade de aritmética (p=0,0003). CONCLUSÃO: O desempenho escolar, assim como as habilidades de consciência fonológica e memória de curto prazo mostraram-se defasados na maioria dos sujeitos avaliados, havendo associação positiva entre: a prova de memória de curto prazo e a prova de aritmética; a prova de consciência fonológica e as provas de leitura e escrita. Neste contexto, reforça-se aqui a utilização de programas de intervenção baseados em Modelos Psicolingüísticos, que sugerem o uso de estratégias individuais para o desenvolvimento das habilidades metafonológicas.
