Sublimação e pulsão de morte: a desfusão pulsional

Com o advento do segundo dualismo pulsional freudiano, surge uma série de mudanças no entendimento da sublimação. Essa passa a se apresentar como a causa por excelência da desfusão das pulsões, o que nos leva a um paradoxo: ao mesmo tempo em que a sublimação é a base da cultura, ela é também causa da destrutividade no seio dessa mesma cultura. A pulsão de morte resultante da desfusão das pulsões, por sua vez, teria consequências tanto em cada indivíduo quanto na cultura como um todo, tal como o que se observa em relação ao primado da imagem na sociedade contemporânea. Este artigo busca discutir alguns dos efeitos da pulsão de morte desfusionada, entendida como resultado da sublimação, principalmente no que tange à sublimação implicada na criação literária.

Determinantes do comportamento de compra verde em Portugal

Apesar do avanço tecnológico, uma grande maioria dos consumidores contínua a utilizar excessivamente os recursos naturais não renováveis do planeta, resultado de um consumo exagerado e inconsciente. Atualmente, os consumidores possuem mais informação sobre as questões ambientais e, alguns, refletem esse conhecimento nas suas decisões de compra. Com a crescente preocupação e atenção, quer por parte da população, quer por parte das organizações governamentais e empresas, para com o meio ambiente e a sua preservação, as questões ecológicas têm cada vez mais importância nas estratégias das empresas. Na presente investigação é analisado o comportamento de compra verde com a utilização das variáveis sociodemográficas (género, idade, número de filhos, rendimento e habilitações literárias) e psicográficas (conhecimento ecológico, coletivismo e individualismo), indo ao encontro do objetivo geral de investigação que visa compreender qual a relevância destas variáveis face ao comportamento de compra verde. O estudo desenvolvido é operacionalizado por via de um método quantitativo, através da utilização de um inquérito por questionário com base nas escalas do conhecimento ecológico (Laroche et al., 2001), coletivismo e individualismo (Singelis et al., 1995 e Triandis & Gelfand (1998)) e do comportamento de compra verde (Jain & Kaur, 2004). O questionário foi aplicado a uma amostra de conveniência (N=350), dando origem a uma análise quantitativa face aos dados obtidos. Os resultados indicam que as variáveis psicográficas exercem maior influência no comportamento de compra verde do que as variáveis sociodemográficas. As variáveis psicográficas, conhecimento ecológico e coletivismo, têm uma grande influência no comportamento de compra verde, ao contrário do individualismo. Por seu lado, do conjunto das variáveis sociodemográficas, apenas a idade e o número de filhos influenciam significativamente o comportamento de compra verde.

Al Berto : Pelas imagens que o espelho te devolve

Dissertação de Mestrado apresentada ao ISPA - Instituto Universitário

Neural detection of complex sound sequences in the absence of consciousness.

The neural response to a violation of sequences of identical sounds is a typical example of the brain's sensitivity to auditory regularities. Previous literature interprets this effect as a pre-attentive and unconscious processing of sensory stimuli. By contrast, a violation to auditory global regularities, i.e. based on repeating groups of sounds, is typically detectable when subjects can consciously perceive them. Here, we challenge the notion that global detection implies consciousness by testing the neural response to global violations in a group of 24 patients with post-anoxic coma (three females, age range 45-87 years), treated with mild therapeutic hypothermia and sedation. By applying a decoding analysis to electroencephalographic responses to standard versus deviant sound sequences, we found above-chance decoding performance in 10 of 24 patients (Wilcoxon signed-rank test, P < 0.001), despite five of them being mildly hypothermic, sedated and unarousable. Furthermore, consistently with previous findings based on the mismatch negativity the progression of this decoding performance was informative of patients' chances of awakening (78% predictive of awakening). Our results show for the first time that detection of global regularities at neural level exists despite a deeply unconscious state.

Créer : le phénomène de la création en donnant la réplique à Antonin Artaud

Le phénomène de la création dans le cadre d’un discours sur la création – la production littéraire et artistique – ne va pas de soi. La tâche de le circonscrire comme un objet est antinomique : l’expérience du discours est en soi une création. Alors que le langage écrit semble au plus souvent «supprimer» l’auteur, le processus de création implique un «Je» créateur qui pense, qui se transforme, qui vit et dont la pensée s’imbrique à son objet qui, quant à lui, est «supprimé»; car il n’est pas extérieur à la pensée mais en relation avec elle. Ce travail, qui démontre le rapport complexe entre l’objet, la critique, le sujet et le commentaire, se penche donc sur l’«avant», le «pendant» et l’«après» de la création, dans un acte de mémoire, qui découle d’une performance littéraire sur la création. Des forces motrices informes et inconscientes, à la mise en forme jusqu’à la transmission, qui lui redonne un caractère d’informe, la création est en mouvement, comme le savoir est toujours prisonnier d’un «work in progress». Tributaire d’Antonin Artaud, le texte s’inscrit à partir de l’artiste en guise d’archétype existentiel, et s’y réfère constamment pour témoigner de la création sans la détacher de la vie et de ses expériences. Pour accéder au mystère du processus de création, lié à la pensée subjective, inobjectivable et irréductible au discours linéaire, ce travail met l’accent sur les associations de la pensée qui procède, exprimées par un «Je» exemplaire omniprésent, tatoué par l’expérience, mais à la position ambiguë à titre d’auteur. Processus de vie, de pensée et de création sont non seulement entremêlés, mais traversés par le champ du tout autre, historique, mondial et social, en perpétuelle évolution. Le rôle du créateur n’est pas de ne créer qu’à partir des connaissances extérieures à lui, mais à partir de lui-même – de son moi multiple et de sa pensée imprégnée de lectures et de ce qui le traverse et l’habite dans un temps donné – pour aboutir à la mise en forme d’un texte cohérent, d’une gravure particulière de l’esprit en marche vers le savoir, qui se situe toujours dans le devenir.

La connaissance des origines de l'enfant adopté: du « besoin» au « droit» Perspectives anthropologique, sociologique et psychologiques pour une réforme législative

Le présent mémoire traite de la nécessité pour le législateur d'instituer des règles permettant aux personnes adoptées de connaître leurs origines. Puisées à travers diverses disciplines telles que l'histoire, l'anthropologie, la sociologie et la psychologie, des connaissances rendent compte des empreintes conscientes et inconscientes laissées chez l'enfant par les parents de naissance. Le besoin de développer son individualité et d'atteindre son plein épanouissement implique que la personne adoptée puisse bénéficier des repères identitaires masqués par le secret des origines. L'accès aux dossiers judiciaires et administratifs de son adoption permet de recouvrer des informations nécessaires au processus d'auto-définition et de d'auto-réalisation de la personne adoptée. Or, les mécanismes de l'adoption au Québec s'avèrent insuffisants pour pallier aux situations actuelles qui ont évolué depuis que le législateur québécois a introduit l'adoption légale en 1924. L'adoption sans rupture du lien d'origine et la délégation judiciaires de l'autorité parentale aux membres de la famille de naissance comptent parmi les dispositifs à intégrer, pour l'un, et à réaménager, pour l'autre, dans l'attente d'une levée inconditionnelle du secret des origines pour la personne adoptée majeure dans toute situation.

Amorçage cognitif pour amélioration de l’acquisition de la connaissance dans un système tutoriel intelligent

Cette thèse vise à définir une nouvelle méthode d’enseignement pour les systèmes tutoriels intelligents dans le but d’améliorer l’acquisition des connaissances. L’apprentissage est un phénomène complexe faisant intervenir des mécanismes émotionnels et cognitifs de nature consciente et inconsciente. Nous nous intéressons à mieux comprendre les mécanismes inconscients du raisonnement lors de l’acquisition des connaissances. L’importance de ces processus inconscients pour le raisonnement est bien documentée en neurosciences, mais demeure encore largement inexplorée dans notre domaine de recherche. Dans cette thèse, nous proposons la mise en place d’une nouvelle approche pédagogique dans le domaine de l’éducation implémentant une taxonomie neuroscientifique de la perception humaine. Nous montrons que cette nouvelle approche agit sur le raisonnement et, à tour de rôle, améliore l’apprentissage général et l’induction de la connaissance dans un environnement de résolution de problème. Dans une première partie, nous présentons l’implémentation de notre nouvelle méthode dans un système tutoriel visant à améliorer le raisonnement pour un meilleur apprentissage. De plus, compte tenu de l’importance des mécanismes émotionnels dans l’apprentissage, nous avons également procédé dans cette partie à la mesure des émotions par des capteurs physiologiques. L’efficacité de notre méthode pour l’apprentissage et son impact positif observé sur les émotions a été validée sur trente et un participants. Dans une seconde partie, nous allons plus loin dans notre recherche en adaptant notre méthode visant à améliorer le raisonnement pour une meilleure induction de la connaissance. L’induction est un type de raisonnement qui permet de construire des règles générales à partir d’exemples spécifiques ou de faits particuliers. Afin de mieux comprendre l’impact de notre méthode sur les processus cognitifs impliqués dans ce type de raisonnement, nous avons eu recours à des capteurs cérébraux pour mesurer l’activité du cerveau des utilisateurs. La validation de notre approche réalisée sur quarante-trois volontaires montre l’efficacité de notre méthode pour l’induction de la connaissance et la viabilité de mesurer le raisonnement par des mesures cérébrales suite à l’application appropriée d’algorithmes de traitement de signal. Suite à ces deux parties, nous clorons la thèse par une discussion applicative en décrivant la mise en place d’un nouveau système tutoriel intelligent intégrant les résultats de nos travaux.

El arte en las psicosis, un abordaje psicoanalítico

En el presente trabajo se realiza una exploración de la posible relación que existe entre la psicosis y el proceso creativo desde una perspectiva psicoanalítica, ilustrando esta relación con el análisis de casos específicos. Con base en una revisión de la literatura sobre los conceptos de psicosis, sublimación y creatividad desde el enfoque psicodinámico, se hace un acercamiento a la teoría de arte Outsider, puntuando algunos aspectos relativos a las obras de determinados artistas en relación con los conceptos revisados.

Domestication of plants revisited - Darwin to the present day

Darwin studied domesticated plants and animals to try to understand the causes of variability. He observed that variation is greatest in the part of the plant most used by humans, but explanations of the causes of this variation had to await the discovery of Mendelian genetics and subsequent advances in the understanding of the structure and mode of action of genes, from the one gene, one enzyme hypothesis to the role of transcriptional regulators. Darwin credited his studies on domesticated plants and animals with demonstrating to him the power of selection. He recognized two forms of human-mediated selection, methodical and unconscious, in addition to natural selection. Selection leaves a signature in the form of reduced diversity in genes that have been the targets of selection and in 'hitch-hiking' genomic regions linked to the target genes. These so-called selective sweeps may serve now to identify genes targeted by selection in early stages of domestication and thus provide a possible guide to crop improvement in future.

Bilayer graphene formed by passage of current through graphite: evidence for a three-dimensional structure

The passage of an electric current through graphite or few-layer graphene can result in a striking structural transformation, but there is disagreement about the precise nature of this process. Some workers have interpreted the phenomenon in terms of the sublimation and edge reconstruction of essentially flat graphitic structures. An alternative explanation is that the transformation actually involves a change from a flat to a three-dimensional structure. Here we describe detailed studies of carbon produced by the passage of a current through graphite which provide strong evidence that the transformed carbon is indeed three-dimensional. The evidence comes primarily from images obtained in the scanning transmission electron microscope using the technique of high-angle annular dark-field imaging, and from a detailed analysis of electron energy loss spectra. We discuss the possible mechanism of the transformation, and consider potential applications of “three-dimensional bilayer graphene”.

Värdefull litteratur : Fyra gymnasielärare om samhällsuppdragets etik i förhållande till litteraturen i klassrummet

The ethical aspects of the Swedish Curriculum for the non-compulsory school system, Lpf94, will form the basis of the research in this essay. The ethical aspects constitute fundamental values and goals as well as common tasks that must be carried out by every teacher. Since the school debate focuses a lot on this perspective, which is often mentioned together with the words problematic and contradictory, it will consequently also be the focus of this essay. Here these features are treated in relation to literature in all its forms used by teachers in class, which also represents a part of the school debate. Together ethics and literature form a perspective that lacks research. The goal is to investigate the ethical awareness of teachers in relation to the literature, and find out which ethical decisions are made by teachers and in what ways the ethical aspects of the curriculum is fulfilled. A qualitative method has been used in order to gain results: four upper secondary school teachers/senior high school teachers have been interviewed. The results are presented in interview transcripts which have been analyzed and interpreted in the light of recent studies and research and pedagogical-didactical literature. Accordingly I have been able to draw the conclusions that the ethical features in teaching is not explicit and that there seldom seems to be any conscious ethical reflections in relation to the literature. The ethical aspects are rather invisible and unconscious. However, it is clear that the interviews raise the awareness of the ethical perspective and thus emphasize the growing and developing function of the dialogue. Finally the results have been interpreted from the point of view of the ethical tasks of the teacher in order to make the ethics visible.I detta examensarbete ligger fokus på de etiska aspekterna av samhällsuppdraget i förhållande till den litteratur som lärare använder sig av i klassrumsundervisningen. Eftersom en stor del av skoldebatten handlar om samhällsuppdraget och dess värdegrund utgör också detta perspektiv utgångspunkten för denna undersökning. Målet är att undersöka vilka etiska avvägningar lärare gör i valet av litteratur och på vilket sätt samhällsuppdragets etik blir synlig i lärares arbete. Därmed framkommer också till viss del i vilken omfattning värdegrundsarbetet sker. Genom en kvalitativ undersökningsmetod i form av samtal har fyra gymnasielärare intervjuats. Erhållna resultat har presenterats i form av intervjutranskript som analyserats och tolkats med hjälp av aktuell forskning och pedagogisk-didaktisk litteratur. De slutsatser som kan dras utifrån resultaten är att etiken i lärarnas arbete inte är explicit och att det oftast inte finns en medveten etisk reflektion utifrån litteraturen. Etiken är snarare osynlig och tämligen omedveten. Dock medvetandegörs den under samtalen vilket framhåller dialogens betydelse för utveckling. Vidare framkommer att etiken aldrig är ett mål i sig, utan fungerar mer som medel för att nå andra mål i klassrummet. Slutligen, för att synliggöra etiken, har resultaten tolkats utifrån de etiska krav i samhällsuppdraget som ställs på lärare.

A Psychoanalytical Reading of Emily Brontë's Wuthering Heights : An Analysis of the Defense Mechanisms of Some Characters

This essay presents a portrayal of Heathcliff, Catherine and Isabella from a psychoanalytical perspective with regard to four defense mechanisms; namely, repression, denial, sublimation and projection in order to see how these defense mechanisms have affected the characters’ decisions and behaviour, and led them to their destinations in life. It will include three major sections: repression in characters, denial in characters, and sublimation and projection in characters. These terms will be more clearly defined and explained in the subsequent sections.

A inscrição psicológica do sintoma: uma aproximação psicoanalítica a psicossomática

Os discursos familiares encerram, no seu bojo, mitos sociais, sentimentos e fantasias inconscientes a eles conectados, que permaneceram secretos e poderosos através de sua historicidade e que vão se inscrever na matéria-prima pura: o recém-nascido, que deve ser moldado mediante o processo de identificação, investimentos libidinais e registro do discurso das pulsões e seus representantes. A partir de uma abordagem psicanalítica dos sintomas psicossomáticos, estudamos os primórdios da constituição do sujeito do inconsciente, recorrendo à estruturação do narcisismo e do inconsciente, construindo-se como uma linguagem ao encadear os significantes por contiguidade ou semelhança, respectivamente, por deslocamentos e condensações, isto é, construindo-se numa cadeia como metonímias e metáforas que se organizam num discurso. O narcisismo seria a causa do corpo. Este último, suporte biológico, que se torna erógeno a partir do discurso materno cujo desejo antecipa uma gestalt à imagem, organizando e delimitando o corpo despedaçado e anárquico do bebê. Como estrutura narcísica relacionamos a articulação das pulsões, das zonas erógenas, do desejo, do recalcamento fixando os representantes que irão constituir um Ego corporal. O sintoma no real do corpo apareceria como efeito de uma desorganização na articulação dos significantes do desejo materno como legalidade de um discurso, dificultando a inscrição simbólica da significação dos limites e fronteiras do corpo erógeno do bebê, cujo representante da pulsão evidencia-se como demanda de significação.

Mapeando fundamentos do Constructo Neuromarketing com profissionais de empresa de publicidade

This study aims to acknowledge the domain level and influence of the neuromarketing construct. This is done considering professionals at advertising agencies in Brazil. The presence of concepts related to this new approach is very little divulged, and there are little analysis performed on this area. Thus, the research is of qualitative and exploratory nature and used as primary fonts books, articles related to marketing, neuroscience, and psychology as well as secondary fonts. A profound interview was realized aiming the main advertising agencies in Brazil. The public was composed by managers responsible for planning. A content analysis was performed afterwards. The advances related to the brain science have permitted the development of technological innovation. These go primarily towards knowledge and unconscious experiences of consumers, which are responsible for the impulse of decision making and consumer behavior. These issues are related to Neuromarketing, that in turn, uses techniques such as FMRI, PET and FDOT. These scan the consumer s brain and produces imagines on the neuron s structures and functioning. This is seen while activities such as mental tasks for the visualization of brands, images or products, watching videos and commercials are performed. It is observed that the agencies are constantly in search of new technologies and are aware of the limitations of the current research instruments. On the other hand, they are not totally familiar with concepts related to neuromarketing. In relation to the neuroimage techniques it is pointed out by the research that there is full unawareness, but some agencies seem to visualize positive impacts with the use of these techniques for the evaluation of films and in ways that permit to know the consumer better. It is also seen that neuroimage is perceived as a technique amongst others, but its application is not real, there are some barriers in the market and in the agencies itself. These barriers as well as some questioning allied to the scarce knowledge of neuromarketing, make it not possible to be put into practice in the advertising market. It is also observed that even though there is greater use of neuromarketing; there would not be any meaningful changes in functioning and structuring of these agencies. The use of the neuro-image machines should be done in research institutes and centers of big companies. Results show that the level of domain of the neuromarketing construct in the Brazilian advertising agencies is only a theoretical one. Little is known of this subject and the neurological studies and absolutely nothing of neuroimage techniques

Concordâncias e discordâncias de Dewey com Freud

Este artigo expõe ideias de Sigmund Freud sobre temas que são fundamentais para compreender o homem contemporâneo: a constituição do psiquismo; a formação e a resolução das patologias mentais; a cultura em sentido amplo e a educação como elemento mediador entre o indivíduo e a sociedade. O objetivo é apresentar e comparar as análises feitas por John Dewey sobre esses mesmos temas, tomando por base o livro Human nature and conduct. As comparações entre os discursos freudiano e deweyano são feitas por meio da metodologia proposta por Chaïm Perelman no livro Tratado da argumentação (elaborado em coautoria com Olbrechts-Tyteca), que busca esclarecer as estratégias argumentativas usadas por um autor para obter ou aumentar a adesão às teses propostas e, com isso, despertar ações concretas. As conclusões sugerem que, embora Dewey discorde de Freud, existem pontos de concordância entre ambos, especialmente no que diz respeito ao significado dos impulsos e da sublimação e à concepção de que o conhecimento é mutável e impreciso, o que rejeita a crença em certezas absolutas e insere as decisões e ações humanas no âmbito da probabilidade.
