Análisis de las necesidades emocionales de los menores con trastorno mental grave del centro terapeútico-educativo de Ortuella y diseño de un programa de desarrollo de competencias emocionales a través de la teatralización

En el presente TFG se ha realizado un diagnóstico de las necesidades emocionales de los menores de entre 6 y 12 años diagnosticados de trastorno mental grave que acuden al Centro Terapéutico-Educativo de Ortuella. En la metodología de análisis se han utilizado dos técnicas.: la observación participante en los distintos espacios en los que se desenvuelven los usuarios y la entrevista con cada uno de los profesionales de la entidad. Este análisis ha tenido como objetivo detectar las carencias emocionales de los usuarios que requieren de mayor atención educativa. Además se realiza una propuesta de intervención cuyo eje central es desarrollar las competencias emocionales a través de la teatralización.

Frictional properties of faults : from observation on the Longitudinal Valley Fault, Taiwan, to dynamic simulations

Faults can slip either aseismically or through episodic seismic ruptures, but we still do not understand the factors which determine the partitioning between these two modes of slip. This challenge can now be addressed thanks to the dense set of geodetic and seismological networks that have been deployed in various areas with active tectonics. The data from such networks, as well as modern remote sensing techniques, indeed allow documenting of the spatial and temporal variability of slip mode and give some insight. This is the approach taken in this study, which is focused on the Longitudinal Valley Fault (LVF) in Eastern Taiwan. This fault is particularly appropriate since the very fast slip rate (about 5 cm/yr) is accommodated by both seismic and aseismic slip. Deformation of anthropogenic features shows that aseismic creep accounts for a significant fraction of fault slip near the surface, but this fault also released energy seismically, since it has produced five M_w>6.8 earthquakes in 1951 and 2003. Moreover, owing to the thrust component of slip, the fault zone is exhumed which allows investigation of deformation mechanisms. In order to put constraint on the factors that control the mode of slip, we apply a multidisciplinary approach that combines modeling of geodetic observations, structural analysis and numerical simulation of the "seismic cycle". Analyzing a dense set of geodetic and seismological data across the Longitudinal Valley, including campaign-mode GPS, continuous GPS (cGPS), leveling, accelerometric, and InSAR data, we document the partitioning between seismic and aseismic slip on the fault. For the time period 1992 to 2011, we found that about 80-90% of slip on the LVF in the 0-26 km seismogenic depth range is actually aseismic. The clay-rich Lichi M\'elange is identified as the key factor promoting creep at shallow depth. Microstructural investigations show that deformation within the fault zone must have resulted from a combination of frictional sliding at grain boundaries, cataclasis and pressure solution creep. Numerical modeling of earthquake sequences have been performed to investigate the possibility of reproducing the results from the kinematic inversion of geodetic and seismological data on the LVF. We first investigate the different modeling strategy that was developed to explore the role and relative importance of different factors on the manner in which slip accumulates on faults. We compare the results of quasi dynamic simulations and fully dynamic ones, and we conclude that ignoring the transient wave-mediated stress transfers would be inappropriate. We therefore carry on fully dynamic simulations and succeed in qualitatively reproducing the wide range of observations for the southern segment of the LVF. We conclude that the spatio-temporal evolution of fault slip on the Longitudinal Valley Fault over 1997-2011 is consistent to first order with prediction from a simple model in which a velocity-weakening patch is embedded in a velocity-strengthening area.

The Madden-Julian Oscillation : observation, modeling, and theory

The Madden-Julian Oscillation (MJO) is a pattern of intense rainfall and associated planetary-scale circulations in the tropical atmosphere, with a recurrence interval of 30-90 days. Although the MJO was first discovered 40 years ago, it is still a challenge to simulate the MJO in general circulation models (GCMs), and even with simple models it is difficult to agree on the basic mechanisms. This deficiency is mainly due to our poor understanding of moist convection—deep cumulus clouds and thunderstorms, which occur at scales that are smaller than the resolution elements of the GCMs. Moist convection is the most important mechanism for transporting energy from the ocean to the atmosphere. Success in simulating the MJO will improve our understanding of moist convection and thereby improve weather and climate forecasting.

We address this fundamental subject by analyzing observational datasets, constructing a hierarchy of numerical models, and developing theories. Parameters of the models are taken from observation, and the simulated MJO fits the data without further adjustments. The major findings include: 1) the MJO may be an ensemble of convection events linked together by small-scale high-frequency inertia-gravity waves; 2) the eastward propagation of the MJO is determined by the difference between the eastward and westward phase speeds of the waves; 3) the planetary scale of the MJO is the length over which temperature anomalies can be effectively smoothed by gravity waves; 4) the strength of the MJO increases with the typical strength of convection, which increases in a warming climate; 5) the horizontal scale of the MJO increases with the spatial frequency of convection; and 6) triggered convection, where potential energy accumulates until a threshold is reached, is important in simulating the MJO. Our findings challenge previous paradigms, which consider the MJO as a large-scale mode, and point to ways for improving the climate models.

OBSERVATION OF CAVITY QUANTUM-ELECTRODYNAMIC EFFECTS IN A ND-GLASS MICROSPHERE

In a Nd:glass microspherical cavity the enhancement and inhibition of spontaneous-emission processes that are due to cavity QED effects have been observed. The rates of the enhanced spontaneous emission are location dependent and reach a maximum value of more than 10(3) times the free-space value. The large enhancement strongly modifies the decay processes of Nd ions in glass, and the radiative properties of Nd:glass have been changed. As a result a new spectrum including new lasing wavelengths in the Nd:glass sphere has been observed.

Part I

The spectrum of dissolved mercury atoms in simple liquids has been shown to be capable of revealing information concerning local structures in these liquids.

Part II

Infrared intensity perturbations in simple solutions have been shown to involve more detailed interaction than just dielectric polarization. No correlation has been found between frequency shifts and intensity enhancements.

Part III

Evidence for perturbed rotation of HCl in rare gas matrices has been found. The magnitude of the barrier to rotation is concluded to be of order of 30 cm^(-1).

Riscos no trabalho do Agente Comunitário de Saúde na perspectiva da saúde do trabalhador

Este estudo tem como objetivo identificar e discutir condições e riscos no trabalho dos Agentes Comunitários de Saúde que atuam em uma Área Programática da cidade do Rio de Janeiro. O referencial teórico foi o da saúde do trabalhador, e as normativas relativas à formação do ACS e de seu processo de profissionalização. O estudo foi realizado em equipes que atuam em duas comunidades, por meio de um estudo de observação sistemática, não-participante, utilizando um roteiro prévio com conteúdo de riscos ocupacionais. Os dados foram coletados a partir do acompanhamento de 23 ACS que realizaram 74 visitas domiciliares nos meses de março a junho de 2008, e organizados sob a forma de um diário de campo descritivo. A organização e análise basearam-se na abordagem qualitativa da análise de conteúdo. Os resultados são apresentados e discutidos segundo a seguinte organização: i) atividades realizadas pelos ACS; ii) comparação entre atividades prescritas e atividades reais e iii) principais riscos identificados e suas possíveis repercussões na saúde do ACS. Nas considerações finais, são discutidas as implicações para o SUS e para a enfermagem, que tem supervisionado os ACS, e a importância de se aprofundar, por meio de estudos posteriores, as situações e condições de trabalho desenvolvido na Atenção Básica.

Observation and interpretation of tectonic strain release mechanisms

In four chapters various aspects of earthquake source are studied.

Chapter I

Surface displacements that followed the Parkfield, 1966, earthquakes were measured for two years with six small-scale geodetic networks straddling the fault trace. The logarithmic rate and the periodic nature of the creep displacement recorded on a strain meter made it possible to predict creep episodes on the San Andreas fault. Some individual earthquakes were related directly to surface displacement, while in general, slow creep and aftershock activity were found to occur independently. The Parkfield earthquake is interpreted as a buried dislocation.

Chapter II

The source parameters of earthquakes between magnitude 1 and 6 were studied using field observations, fault plane solutions, and surface wave and S-wave spectral analysis. The seismic moment, M_O, was found to be related to local magnitude, M_L, by log M_O = 1.7 M_L + 15.1. The source length vs magnitude relation for the San Andreas system found to be: M_L = 1.9 log L - 6.7. The surface wave envelope parameter AR gives the moment according to log M_O = log AR₃₀₀ + 30.1, and the stress drop, τ, was found to be related to the magnitude by τ = 0.54 M - 2.58. The relation between surface wave magnitude M_S and M_L is proposed to be M_S = 1.7 M_L - 4.1. It is proposed to estimate the relative stress level (and possibly the strength) of a source-region by the amplitude ratio of high-frequency to low-frequency waves. An apparent stress map for Southern California is presented.

Chapter III

Seismic triggering and seismic shaking are proposed as two closely related mechanisms of strain release which explain observations of the character of the P wave generated by the Alaskan earthquake of 1964, and distant fault slippage observed after the Borrego Mountain, California earthquake of 1968. The Alaska, 1964, earthquake is shown to be adequately described as a series of individual rupture events. The first of these events had a body wave magnitude of 6.6 and is considered to have initiated or triggered the whole sequence. The propagation velocity of the disturbance is estimated to be 3.5 km/sec. On the basis of circumstantial evidence it is proposed that the Borrego Mountain, 1968, earthquake caused release of tectonic strain along three active faults at distances of 45 to 75 km from the epicenter. It is suggested that this mechanism of strain release is best described as "seismic shaking."

Chapter IV

The changes of apparent stress with depth are studied in the South American deep seismic zone. For shallow earthquakes the apparent stress is 20 bars on the average, the same as for earthquakes in the Aleutians and on Oceanic Ridges. At depths between 50 and 150 km the apparent stresses are relatively high, approximately 380 bars, and around 600 km depth they are again near 20 bars. The seismic efficiency is estimated to be 0.1. This suggests that the true stress is obtained by multiplying the apparent stress by ten. The variation of apparent stress with depth is explained in terms of the hypothesis of ocean floor consumption.

Museu de Favela: pensando turismo e patrimônio no Pavão, Pavãozinho e Cantagalo

Esta dissertação versa sobre o Museu de Favela (MUF), organização não-governamental fundada em 2008 durante as obras do Programa de Aceleração do Crescimento (PAC) nas favelas do Pavão, Pavãozinho e Cantagalo, na Zona Sul da cidade do Rio de Janeiro. As principais propostas do MUF são a patrimonialização da favela/seus elementos culturais, bem como o desenvolvimento turístico dessas favelas. A partir de um trabalho de campo, do tipo observação participante junto à diretoria do MUF, analiso a construção de sua proposta de turismo em oposição à favela da Rocinha, caso emblemático do turismo em favelas. Mostro a presença de duas ideias de turismo a propósito do caso estudado: o que chamo de turismo vilão, representado pelo contexto da Rocinha na visão dos promotores do MUF; e o que chamo de turismo solução, representado na mesma visão pelo turismo organizado pelos moradores para benefício da população local e solução dos problemas das favelas. Analiso ainda a proposta do MUF, sua organização como ONG e seus diretores. Por fim, focalizo o Museu de Favela e o Estado como atores sociais básicos envolvidos na questão analisada, mostrando como turismo e patrimônio aparecem como ferramentas para ambas as instituições, que guardam semelhanças e diferenças no que se refere a dois processos em andamento nas favelas do Pavão, Pavãozinho e Cantagalo: o processo de patrimonialização e o processo de turismização.

High frequency wave propagation in the earth: theory and observation

The wave-theoretical analysis of acoustic and elastic waves refracted by a spherical boundary across which both velocity and density increase abruptly and thence either increase or decrease continuously with depth is formulated in terms of the general problem of waves generated at a steady point source and scattered by a radially heterogeneous spherical body. A displacement potential representation is used for the elastic problem that results in high frequency decoupling of P-SV motion in a spherically symmetric, radially heterogeneous medium. Through the application of an earth-flattening transformation on the radial solution and the Watson transform on the sum over eigenfunctions, the solution to the spherical problem for high frequencies is expressed as a Weyl integral for the corresponding half-space problem in which the effect of boundary curvature maps into an effective positive velocity gradient. The results of both analytical and numerical evaluation of this integral can be summarized as follows for body waves in the crust and upper mantle:

1) In the special case of a critical velocity gradient (a gradient equal and opposite to the effective curvature gradient), the critically refracted wave reduces to the classical head wave for flat, homogeneous layers.

2) For gradients more negative than critical, the amplitude of the critically refracted wave decays more rapidly with distance than the classical head wave.

3) For positive, null, and gradients less negative than critical, the amplitude of the critically refracted wave decays less rapidly with distance than the classical head wave, and at sufficiently large distances, the refracted wave can be adequately described in terms of ray-theoretical diving waves. At intermediate distances from the critical point, the spectral amplitude of the refracted wave is scalloped due to multiple diving wave interference.

These theoretical results applied to published amplitude data for P-waves refracted by the major crustal and upper mantle horizons (the Pg, P*, and Pn travel-time branches) suggest that the 'granitic' upper crust, the 'basaltic' lower crust, and the mantle lid all have negative or near-critical velocity gradients in the tectonically active western United States. On the other hand, the corresponding horizons in the stable eastern United States appear to have null or slightly positive velocity gradients. The distribution of negative and positive velocity gradients correlates closely with high heat flow in tectonic regions and normal heat flow in stable regions. The velocity gradients inferred from the amplitude data are generally consistent with those inferred from ultrasonic measurements of the effects of temperature and pressure on crustal and mantle rocks and probable geothermal gradients. A notable exception is the strong positive velocity gradient in the mantle lid beneath the eastern United States (2 x 10^-3 sec^-1), which appears to require a compositional gradient to counter the effect of even a small geothermal gradient.

New seismic-refraction data were recorded along a 800 km profile extending due south from the Canadian border across the Columbia Plateau into eastern Oregon. The source for the seismic waves was a series of 20 high-energy chemical explosions detonated by the Canadian government in Greenbush Lake, British Columbia. The first arrivals recorded along this profile are on the Pn travel-time branch. In northern Washington and central Oregon their travel time is described by T = Δ/8.0 + 7.7 sec, but in the Columbia Plateau the Pn arrivals are as much as 0.9 sec early with respect to this line. An interpretation of these Pn arrivals together with later crustal arrivals suggest that the crust under the Columbia Plateau is thinner by about 10 km and has a higher average P-wave velocity than the 35-km-thick, 62-km/sec crust under the granitic-metamorphic terrain of northern Washington. A tentative interpretation of later arrivals recorded beyond 500 km from the shots suggests that a thin 8.4-km/sec horizon may be present in the upper mantle beneath the Columbia Plateau and that this horizon may form the lid to a pronounced low-velocity zone extending to a depth of about 140 km.

Nos braços da lei: o uso daviolência negociada no interior das prisões

O presente estudo objetiva, a partir da narrativa do trabalhador prisional da SEAP-RJ, abordar em que situações e com base em quais justificativas esse profissional recorre ao uso da força física em seu cotidiano prisional. A rotina de trabalho dos agentes penitenciários é apresentada a partir de um estudo de caso realizado no Instituto Presídio Hélio Gomes. Nele, os relatos dos integrantes das turmas de guardas se constituíram em nossa principal fonte de informações. Em outra fase da pesquisa, o processo de formação profissional dos servidores prisionais admitidos em 2004, pela SEAP-RJ, foi acompanhado através das aulas ministradas na Escola de Gestão Penitenciária. Em ambos os casos, a observação participante foi o instrumento metodológico que me permitiu a coleta de dados e a interação com o grupo estudado. A narrativa está centrada no processo de socialização por que passam os servidores prisionais para se integrarem a (s) moralidade (s) vigente nas prisões. Sugere-se que a integração plena do operador da lei ao universo prisional, implique em sua socialização no mundo do crime. A possibilidade de uso da violência física como mecanismo de controle, em sua modalidade violência negociada, mostrou-se uma hipótese viável. Porém, ainda necessita de maiores comprovações empíricas, em especial junto aos internos penitenciários, para que possa ser formalmente validada.
