Anàlisi de models d'intervenció pedagògica i psicologia a les escoles. 'Análisis de modelos de intervención pedagógica y psicológica en las escuelas'.

Analizar los ECR. A/ Encuadre conceptual referencial operativo y los instrumentos de intervención pedagógica y psicológica en las escuelas así como las funciones de los maestros, alumnos y psicólogos en la Institución escolar. 8 escuelas: 4 privadas, 4 laicas, 7 privadas y 1 estatal seleccionadas según los criterios: tener un psicólogo o un equipo psicológico en las escuelas y posibilidad de encuadrarse en dos grupos diferentes en cuanto al modelo pedagógico. Lleva a cabo un estudio empírico centrado en el análisis y comparación de los modelos de intervención pedagógica y psicológica en las escuelas. Cuantifica los datos mediante la definición de unas dimensiones y la creación de unos indicadores e ítems para cada aspecto diferenciador de los modelos constructivista y de transmisión de adquisición del conocimiento. Analiza los datos configuradores de ambos modelos en las 8 escuelas mediante análisis descriptivo y concluye con un análisis comparativo de los dos grupos de escuelas. Observación directa. Encuestas individuales a los alumnos de primero y octavo. Entrevistas a los profesores o tutores y a los psicólogos. Estadística descriptiva. Dos escuelas se vinculan con el modelo constructivista e interactivo de intervención pedagógica. Los instrumentos que se movilizan son las actividades comunicativas del alumno con el medio. Otras dos se encuadran en el modelo de transmisión del conocimiento. Estos dependen del maestro y sólo obtienen conocimiento de aquello que le transmite el maestro. Otras dos se enmarcan en una posición intermedia. Respecto a la intervención psicológica, se observan dos directrices básicas: psicopedagógico contextualizador y psicopedagógico descontextualizador: intervención puntual. No tiene en cuenta el medio de donde sale el fracaso escolar. Las funciones de alumnos y maestros están en consonancia con los ECRO e instrumentos de nivel instrumental-ideológico de las escuelas. En todas las escuelas se observa una convergencia entre los tres aspectos analizados con uno de los modelos de intervención pedagógica definidos.

Producción e interpretación de textos escritos por niños sordos pequeños integrados en escuelas ordinarias.

Averiguar si las escrituras iniciales de niños sordos presentan semejanzas con las que señala la evolución psicogenética de adquisición de la escritura en niños oyentes tal como fueron descritas por E. Ferreiro y A. Teberosky (1979). 9 niños sordos prelocutivos de entre 3 y 7 años de edad. Se lleva a cabo un seguimiento longitudinal durante un curso escolar repartido en 6 sesiones con intervalos de un mes y medio. Se presentan a los niños sordos distintas tareas de interpretación y producción de textos escritos, correspondientes a las partes del diagnóstico para niños oyentes sobre adquisición del lenguaje escrito, diseñadas por las autoras citadas. Estas tareas se muestran en entrevistas clínicas (que son registradas en vídeo) y con transcripciones manuales. El análisis de los datos es cualitativo y descriptivo. La evolución de escrituras espontáneas de los niños sordos es similar a la de los oyentes. El nivel de competencia lingüística verbal incide en la escritura. A medida que la evolución se produce, la presencia del lenguaje es ineludible para guiar la construcción de la escritura. Los niños sordos no están imposibilitados 'per se' para acceder al lenguaje escrito, aunque es preciso que se cumplan dos condiciones: un amplio repertorio lexical y la realización de anticipaciones del sentido del texto.

Intratemporal facial nerve ultrastructure in patients with idiopathic facial paralysis. Viral infection evidence study

The etiology of idiopathic peripheral facial palsy (IPFP) is still uncertain; however, some authors suggest the possibility of a viral infection. Aim: to analyze the ultrastructure of the facial nerve seeking viral evidences that might provide etiological data. Material and Methods: We studied 20 patients with peripheral facial palsy (PFP), with moderate to severe FP, of both genders, between 18-60 years of age, from the Clinic of Facial Nerve Disorders. The patients were broken down into two groups - Study: eleven patients with IPFP and Control: nine patients with trauma or tumor-related PFP. The fragments were obtained from the facial nerve sheath or from fragments of its stumps - which would be discarded or sent to pathology exam during the facial nerve repair surgery. The removed tissue was fixed in 2% glutaraldehyde, and studied under Electronic Transmission Microscopy. Results: In the study group we observed an intense repair cellular activity by increased collagen fibers, fibroblasts containing developed organelles, free of viral particles. In the control group this repair activity was not evident, but no viral particles were observed. Conclusion: There were no viral particles, and there were evidences of intense activity of repair or viral infection.

Bell's locality condition confronting perfect anti-correlations

We show that Local Realistic Theories, defined as obeying the Bells's locality condition, cannot satisfy the prefect anti-correlations without at the same time maximally violating rotational symmetry at the hidden variable level. We examine whether the rotational symmetry can be restored after the statistical average. We also comment on the question whether such theories are necessarily deterministic at the hidden variable leva. © 1999 Elsevier Science B.V. All rights reserved.

Implicações clínicas da doença de Lyme em região facial: revisão da literatura

Lyme disease (LD) is a systemic infl ammatory changes resulting from direct action and the immune response to the spirochete Borrelia burgdoferi transmitted by inoculation of the fl ow of the genus Ixodes tick and is most commonly found in North America, Europe and Asia. This disease can lead to facial and peripheral neurological manifestations, such as Bell’s palsy, eye changes, disorders in the temporo-mandibular joint in addition to paresthesia of superior and inferior alveolar nerves. In Brazil, the diagnosis of LD is primarily based on clinical presentation, the erythema migrans skin, and epidemiological information of the patient. Recognition of the onset of the DL by health professionals is essential for the correct antibiotic treatment preventing the progression of the disease, and also relevant preventive guidelines for those living or working in endemic areas.

The effect of osmolytes on protein fold stability at the single-molecule level

By pulling and releasing the tension on protein homomers with the Atomic Force Miscroscope (AFM) at different pulling speeds, dwell times and dwell distances, the observed force-response of the protein can be fitted with suitable theoretical models. In this respect we developed mathematical procedures and open-source computer codes for driving such experiments and fitting Bell’s model to experimental protein unfolding forces and protein folding frequencies. We applied the above techniques to the study of proteins GB1 (the B1 IgG-binding domain of protein G from Streptococcus) and I27 (a module of human cardiac titin) in aqueous solutions of protecting osmolytes such as dimethyl sulfoxide (DMSO), glycerol and trimethylamine N-oxide (TMAO). In order to get a molecular understanding of the experimental results we developed an Ising-like model for proteins that incorporates the osmophobic nature of their backbone. The model benefits from analytical thermodynamics and kinetics amenable to Monte-Carlo simulation. The prevailing view used to be that small protecting osmolytes bridge the separating beta-strands of proteins with mechanical resistance, presumably shifting the transition state to significantly higher distances that correlate with the molecular size of the osmolyte molecules. Our experiments showed instead that protecting osmolytes slow down protein unfolding and speed-up protein folding at physiological pH without shifting the protein transition state on the mechanical reaction coordinate. Together with the theoretical results of the Ising-model, our results lend support to the osmophobic theory according to which osmolyte stabilisation is a result of the preferential exclusion of the osmolyte molecules from the protein backbone. The results obtained during this thesis work have markedly improved our understanding of the strategy selected by Nature to strengthen protein stability in hostile environments, shifting the focus from hypothetical protein-osmolyte interactions to the more general mechanism based on the osmophobicity of the protein backbone.

Una grande narrazione del capitalismo: potere e scienze sociali nel pensiero politico di Daniel Bell

Questa tesi punta a ricostruire il pensiero politico di Bell tra il secondo dopoguerra e la metà degli anni Settanta. In tale arco cronologico, la riflessione politica di Bell si profila, per usare una formula di Jean-François Lyotard, come una «grande narrazione» del capitalismo. Nel complesso, cioè, l’opera di Bell appare come una storia sociologica del capitalismo, che nella fine delle ideologie registra l’apogeo del fordismo e, in seguito, ne mette in luce le trasformazioni in senso post-industriale, indagando le ricadute che tali mutamenti implicano sul piano dei rapporti di potere e della legittimazione del sistema. Nell’ottica di Bell, pertanto, il capitalismo non costituisce soltanto un sistema economico, ma la forma specifica attraverso cui si dispiega la società nel suo complesso, attivando una serie di rapporti di potere mediante i quali gli individui vengono coordinati e subordinati. Una siffatta concezione del capitalismo agisce immediatamente la questione del potere e solleva un interrogativo a esso connesso: «che cosa tiene insieme una società?». Una domanda che attraversa la traiettoria intellettuale di Bell e, sia pure declinata mediante una terminologia sociologica, riflette in realtà l’ambizione delle scienze sociali di farsi teoria politica. Esse si presentano quindi come teoria politica della modernità, nella misura in cui distinguono il potere sociale dal potere politico e, al tempo stesso, instaurano tra i due poli una tensione dialettica produttiva. Mettendo a fuoco la concettualizzazione del potere nell’opera di Bell si analizzeranno le mutazioni nel rapporto tra Stato e società negli Stati Uniti durante la Golden Age del capitalismo. In particolare, si metterà in luce nella grande narrazione di Bell l’ascesa e il declino di un ordine istituzionale che, alla metà degli anni Settanta, appare percorso da molteplici tensioni politiche e sociali che preannunciano l’avvento dell’età globale e il bisogno di una nuova “scala” di governo.

QUANTUM CORRELATIONS OF LIGHTS IN MACROSCOPIC ENVIRONMENTS

This dissertation presents a detailed study in exploring quantum correlations of lights in macroscopic environments. We have explored quantum correlations of single photons, weak coherent states, and polarization-correlated/polarization-entangled photons in macroscopic environments. These included macroscopic mirrors, macroscopic photon number, spatially separated observers, noisy photons source and propagation medium with loss or disturbances. We proposed a measurement scheme for observing quantum correlations and entanglement in the spatial properties of two macroscopic mirrors using single photons spatial compass state. We explored the phase space distribution features of spatial compass states, such as chessboard pattern by using the Wigner function. The displacement and tilt correlations of the two mirrors were manifested through the propensities of the compass states. This technique can be used to extract Einstein-Podolsky-Rosen correlations (EPR) of the two mirrors. We then formulated the discrete-like property of the propensity Pb(m,n), which can be used to explore environmental perturbed quantum jumps of the EPR correlations in phase space. With single photons spatial compass state, the variances in position and momentum are much smaller than standard quantum limit when using a Gaussian TEM00 beam. We observed intrinsic quantum correlations of weak coherent states between two parties through balanced homodyne detection. Our scheme can be used as a supplement to decoy-state BB84 protocol and differential phase-shift QKD protocol. We prepared four types of bipartite correlations ±cos2(θ12) that shared between two parties. We also demonstrated bits correlations between two parties separated by 10 km optical fiber. The bits information will be protected by the large quantum phase fluctuation of weak coherent states, adding another physical layer of security to these protocols for quantum key distribution. Using 10 m of highly nonlinear fiber (HNLF) at 77 K, we observed coincidence to accidental-coincidence ratio of 130±5 for correlated photon-pair and Two-Photon Interference visibility >98% entangled photon-pair. We also verified the non-local behavior of polarization-entangled photon pair by violating Clauser-Horne-Shimony-Holt Bell’s inequality by more than 12 standard deviations. With the HNLF at 300 K (77 K), photon-pair production rate about factor 3(2) higher than a 300 m dispersion-shifted fiber is observed. Then, we studied quantum correlation and interference of photon-pairs; with one photon of the photon-air experiencing multiple scattering in a random medium. We observed that depolarization noise photon in multiple scattering degrading the purity of photon-pair, and the existence of Raman noise photon in a photon-pair source will contribute to the depolarization affect. We found that quantum correlation of polarization-entangled photon-pair is better preserved than polarization-correlated photon-pair as one photon of the photon-pair scattered through a random medium. Our findings showed that high purity polarization-entangled photon-pair is better candidate for long distance quantum key distribution.
