As especificidades da clínica psicanalítica com crianças na neurose e na psicose: conseqüências para a direção do tratamento

This dissertation aims to answer the question: What are the specifics of psychoanalytical clinic with children in neurosis and psychosis and its consequences for the treatment direction? It constitutes a theoretical study based on Freud, Lacan and the current productions of Lacanian psychoanalysts about the clinic with children. It presents some clinical vignettes. To answer this question, were constructed four chapters. The chapter The subject constitution treats the psychoanalysis subjectivity, based on a structure from the relationship with the Other. Key concepts of Lacanian psychoanalysis are shown, necessary to understand what becomes present in clinic with children. The second chapter, The clinic of neurosis, reveals the structure of the subject in its oedipal mooring held by the Name-of the-Father, that separates the mother-child dual relationship. The child neurosis is the effect of psyche constitution and the symptoms are an interpretation of what child picks up from parents and helps him/her on the passage through the Oedipus. The analyst is there to help him/her through this path. The next chapter is entitled The clinic of psychosis. In psychosis the non-occurrence of the Name-of-the-Father is concerned. The subject is stuck in duality with the mother, and becomes what fills the Other s gap. To protect themselves, they have to be in incessant work. The analyst will be a child s partner in daily work already carried out by him/her. The last chapter, The consequences for the treatment direction, shows that the standard analytic treatment works well to the clinic of neurosis. To psychosis it s not true. Psychoanalysts thought about a different way of psychotic children treatment: the practice held in a multiprofessional team work. The practice shared by many has been a team strategy applied to the institutional practice that aims to attenuate the invasive character of the Other, facilitating the partnership between the analyst and the child in treatment and the Other contention

A questão do estilo na psicanálise lacaniana

Lacanian psychoanalysis has won a considerable space in brazilian university: a search for Lacan in the field of subject of the CAPES Thesis Bank shows 1.032 results! However the difference in the style of knowledge production and language usage is considerable between academic psychology and lacanian theory. The difficulty in reading and understanding Lacan is something pointed out by supporters and critics alike. In addition to that, his disciples choose many times to imitate his baroque, complex style, full of neologisms, causing perplexity in many unprepared audiences. What is the origin of such an enigmatic and polemic style of expression? How it became so widespread under the sign of repetition? And which are the consequences of this style to the communication, transmission and teaching of lacanian psychoanalysis? Through these questions it is our goal to contribute to the dialogue between lacanian psychoanalysis and the academy, to provide a better understanding of the causes of this style, analyzing the consequences it has to the transmission of psychoanalysis. We chose to perform a theoretical study, using authors that have treated Lacan s style and the history of psychoanalysis from a critical point of view, like Beividas (2000), Roustang (1987, 1988) and Gellner (1988), and also those that have defended and justified its legitimacy, like Glynos e Stavrakakis (2001), Fink (1997) and Souza (1985), using as well some works by Freud and Lacan. The study of these texts has led us to three main themes: 1) the difficulty of the lacanian text; 2) Lacan, heir of Freud; 3) consequences of the lacanian style. In the first one, we enumerate many different explanations and interpretations given by commentators about the difficulty and particularity of the lacanian discourse; in the second, we show how Lacan came to occupy the place of great idealization that was before destined to Freud, what made his style something to be taken as a model, to be imitated by disciples; in the third, we explore the way in which the concepts are treated in lacanian psychoanalysis, arguing that their multiple meanings point out that the final goal is not to build a clear and coherent theory, but to try to aim directly at the subject, to catch him

O Serviço Residencial Terapêutico: cartografias de um híbrido no contexto da desinstitucionalização em saúde mental

This thesis seeks to uphold the idea that the therapeutic residential service, as hybrid device and recent process of deinstitutionalization in mental health, works as a problem producer while it also indicates challenges and potentialities in this process, the attention on mental health and on its own care production. To that end, we work with the prospect map with which we approach reality as the subjectivities production field which transformations and intensities are the major thought propellants. From this perspective, it was possible to produce three "purpose maps" from meetings with actors and groups involved with the TRS and the theoretical study carried out. On the first map we mapped the conditions of possibility of this device and its design in the midst of the process of institutionalization and health policies. We indicate on it the TRS configuration as a hybrid and we hassled its proposition as a means of "social rehabilitation" that can work as a social homogeneity mechanism. On a second map, we cartographied mental captures through images and ways historically built from madness presented in the biopolitical contemporary game and we indicated that the resistance to such catches should be built on a politic daily basis as important vectors of the institutionalization process in mental health. Finally, on a third map we mapped the carefulness produced in the TRS, by analyzing the transition psychiatric hospital - TRS and the caregivers´ team work. On this mapping, the care, for the weakness in the coresponsibility field, is reveled crossed by mental, disciplinary and normality elements, but it is also built in resistance born from links in the intersubjective field of the caring work. We conclude, then, that the TRS power and the deinstitutionalization process itself were in building and strengthening affective labor micro political networks of life and liberty producers

Nucleação de vortices em nanoelementos elípticos

The present work reports a theoretical study of the vortex nucleation in elliptical nanoelements of iron with the dimensions of the principal and secondary axes in the range of hundreds of nanometers. It will be divided into three steps: first of all, a general panorama and a justification for the interest of the study of nanosystems and their applications. Second, a explanation about the computational simulations applied for the calculations of the remanent states after the saturation in a external field which value is grater then the exchange field of the material for nanoelements coupled or not to a antiferromagnetic substrate. Systems with that range of axes dimensions and height in the range of a few dozens of nanometers have a natural tendency to nucleate closed magnetic ux, like vortex. Third, we will emphasize the nucleation of double vortex, the main types and the dimensions in which they occur (phase diagram) and the factors that may in uence in the nucleation and control of the remanent state. We shown that we can control specially the distance between the vortex cores changing the value of the interface field. Finally, we present a expectative of continuity of this work with objectives and applications

The role of defect states in the creation of photoluminescence in SrTiO3

We discuss the nature of visible photoluminescence at room temperature in amorphous strontium titanate in the light of the results of a recent experimental and quantum mechanical theoretical study. Our calculation of the electronic structure involves the use of first-principles molecular calculations to simulate the variation of the electronic structure in the strontium titanate crystalline phase, which is known to have a direct band gap, and we also make an in-depth examination of amorphous strontium titanate. The results of our simulations of amorphous strontium titanate indicate that the formation of five-fold coordination in the amorphous system may introduce delocalized electronic levels in the highest occupied molecular orbital and the lowest unoccupied molecular orbital. These delocalized electronic levels are ascribed to the formation of a tail in the absorbance-spectrum curve. Optical absorption measurements experimentally showed the presence of a tail. The results are interpreted by the nature of these exponential optical edges and tails associated with defects promoted by the disordered structure of the amorphous material. We associate them with localized states in the band gap.

Mechanisms behind blue, green, and red photoluminescence emissions in CaWO4 and CaMoO4 powders

A combined experimental and theoretical study was conducted to analyze the photoluminescence (PL) properties of ordered and disordered CaWO4 (CW) and CaMoO4 (CM) powders. Two mechanisms were found to be responsible for photoluminescence emission in CW and CM powders. The first one, in the disordered powders, was caused by oxygen complex vacancies [MO3 center dot V-O(x)], [MO3 center dot V-O(center dot)] and [MO3 center dot V-O(center dot center dot)], where M=W or Mo, which leads to additional levels in the band gap. The second mechanism, in ordered powders, was caused by an intrinsic slight distortion of the [WO4] or [MoO4] tetrahedral in the short range. (c) 2007 American Institute of Physics.

BaZrO3 Photoluminescence Property: An Ab Initio Analysis of Structural Deformation and Symmetry Changes

This article reports a theoretical study based on experimental results for barium zirconate, BaZrO3 (BZ) thin films, using periodic mechanic quantum calculations to analyze the symmetry change in a structural order-disorder simulation. Four periodic models were simulated using CRYSTAL98 code to represent the ordered and disordered BZ structures. The results were analyzed in terms of the energy level diagrams and atomic orbital distributions to explain and understand the BZ photoluminescence properties (PL) at room temperature for the disordered structure based on structural deformation and symmetry changes.

Influência da oclusão bilateral das artérias carótidas comuns sobre a atividade vagal

The effects of carotid occlusion on parasympathetic activity were studied in anesthetized dogs submitted to beta adrenergic blockade. Modifications of the heart rate, before and after administration of atropine, were utilized for assessment of vagal changes. When vagal activity was intact there was elevation of the heart rate. After parasympathetic blockade carotid occlusion did not cause heart rate modifications. The data suggest that carotid occlusion produced vagal inhibition.

Efeitos do fentanil, droperidol e inoval sobre função renal e eletrólitos (sódio e potássio)

The influence of Fentanyl, Droperidol and Innovar on renal function and electrolytes (sodium and potassium) were studied on 18 dogs. Fentanyl disturbs kidney function and decreases plasmatic potassium. Droperidol and Innovar do not disturb the main renal function but decrease plasmatic potassium. The results obtained point out the importance of associate employment of Fentamyl and Droperidol, since the latter seems to establish the renal disorders occasioned by Fentanyl, probably owing to its adrenergic α blocking action.
