DE PROFESSORA À PESQUISADORA: A FORMAÇÃO DA IDENTIDADE DOCENTE NO ENSINO SUPERIOR

Esta pesquisa refere-se à formação da identidade docente no Ensino Superior que se caracteriza pela indissocialibilidade entre o ensino, a pesquisa e a extensão. A metodologia utilizada é a História Oral, por meio de Relatos Orais de Vida de quatro professoras que lecionam na pós-graduação de uma universidade privada. A principal fundamentação teórica: António Nóvoa, (1988, 2009), Luis Antonio Cunha (1980, 1997), Dermeval Saviani, (2001), Antonio Joaquim Severino, (2001), Carlos Benedito Martins, (1981, 2002), Gaston Pineau, (2006) e Maria Isaura de Pereira Queiroz, (1988, 1999, 2010). A noção de identidade profissional docente advém das posturas e concepções atribuídas por diferentes discursos e agentes sociais aos professores e às professoras no exercício de suas variadas atividades docentes em distintos contextos, ou seja, em distintas instituições de ensino. Analisa-se o exercício da docência do ensino superior e os saberes desta profissão, os quais tanto possibilitam a formação de futuros docentes com uma visão da importância da metodologia científica, quanto proporciona um salto de qualidade e de atualização contínua condizente com as exigências do ensino superior, atreladas à importância da responsabilidade social.

Numerical study of the enlarged O(5) symmetry of the 3D antiferromagnetic RP^(2) spin model

We investigate by means of Monte Carlo simulation and finite-size scaling analysis the critical properties of the three dimensional O (5) non-linear σ model and of the antiferromagnetic RP^(2) model, both of them regularized on a lattice. High accuracy estimates are obtained for the critical exponents, universal dimensionless quantities and critical couplings. It is concluded that both models belong to the same universality class, provided that rather non-standard identifications are made for the momentum-space propagator of the RP^(2) model. We have also investigated the phase diagram of the RP^(2) model extended by a second-neighbor interaction. A rich phase diagram is found, where most of the phase transitions are of the first order.

Phase diagram of the bosonic double-exchange model

The phase diagram of the simplest approximation to double-exchange systems, the bosonic double-exchange model with antiferromagnetic (AFM) superexchange coupling, is fully worked out by means of Monte Carlo simulations, large-N expansions, and variational mean-field calculations. We find a rich phase diagram, with no first-order phase transitions. The most surprising finding is the existence of a segmentlike ordered phase at low temperature for intermediate AFM coupling which cannot be detected in neutron-scattering experiments. This is signaled by a maximum (a cusp) in the specific heat. Below the phase transition, only short-range ordering would be found in neutron scattering. Researchers looking for a quantum critical point in manganites should be wary of this possibility. Finite-size scaling estimates of critical exponents are presented, although large scaling corrections are present in the reachable lattice sizes.

Phase diagram and influence of defects in the double perovskites

The phase diagram of the double perovskites of the type Sr_(2-x)La_(x)FeMoO_(6) is analyzed, with and without disorder due to antisites. In addition to an homogeneous half metallic ferrimagnetic phase in the absence of doping and disorder, we find antiferromagnetic phases at large dopings, and other ferrimagnetic phases with lower saturation magnetization, in the presence of disorder.

Off-equilibrium fluctuation-dissipation relations in the 3d Ising spin glass in a magnetic field

We study the fluctuation-dissipation relations for a three dimensional Ising spin glass in a magnetic field both in the high temperature phase as well as in the low temperature one. In the region of times simulated we have found that our results support a picture of the low temperature phase with broken replica symmetry, but a droplet behavior cannot be completely excluded.

Dynamical generation of a gauge symmetry in the double-exchange model

It is shown that a bosonic formulation of the double-exchange model, one of the classical models for magnetism, generates dynamically a gauge-invariant phase in a finite region of the phase diagram. We use analytical methods, Monte Carlo simulations and finite-size scaling analysis. We study the transition line between that region and the paramagnetic phase. The numerical results show that this transition line belongs to the universality class of the antiferromagnetic RP^(2) model. The fact that one can define a universality class for the antiferromagnetic RP^(2) model, different from the one of the O(N) models, is puzzling and somehow contradicts naive expectations about universality.

Interplay between double-exchange, superexchange, and Lifshitz localization in doped manganites

Considering the disorder caused in manganites by the substitution Mn→Fe or Ga, we accomplish a systematic study of doped manganites begun in previous papers. To this end, a disordered model is formulated and solved using the variational mean-field technique. The subtle interplay between double exchange, superexchange, and disorder causes similar effects on the dependence of T_(C) on the percentage of Mn substitution in the cases considered. Yet, in La_(2/3)Ca_(1/3)Mn_(1-y)Ga_(y)O_(3) our results suggest a quantum critical point (QCP) for y ≈ 0.1–0.2, associated to the localization of the electronic states of the conduction band. In the case of La_(x)Ca_(x)Mn_(1-y)Fe_(y)O_(3) (with x = 1/3,3/8) no such QCP is expected.

Monte Carlo determination of the phase diagram of the double-exchange model

We study the phase diagram of the double exchange model, with antiferromagnetic interactions, in a cubic lattice both at zero and finite temperature. There is a rich variety of magnetic phases, combined with regions where phase separation takes place. We identify phases, intrinsic to the cubic lattice, which are stable for realistic values of the interactions and dopings. Some of these phases break chiral symmetry, leading to unusual features.

Universal critical behavior of the two-dimensional Ising spin glass

We use finite size scaling to study Ising spin glasses in two spatial dimensions. The issue of universality is addressed by comparing discrete and continuous probability distributions for the quenched random couplings. The sophisticated temperature dependency of the scaling fields is identified as the major obstacle that has impeded a complete analysis. Once temperature is relinquished in favor of the correlation length as the basic variable, we obtain a reliable estimation of the anomalous dimension and of the thermal critical exponent. Universality among binary and Gaussian couplings is confirmed to a high numerical accuracy.

La enseñanza oficial de cine en España

En este artículo se recoge la historia de la enseñanza oficial de cine en España: los dos centros en los que se llevó a cabo, sus sedes, sus directores y las prácticas de fin de carrera. Todo ello visto desde la división en tres etapas del tiempo de existencia de la enseñanza anterior a su incorporación a la universidad: la etapa fundacional, la edad de oro y la crisis que lleva al cierre. A lo largo de estas tres etapas hubo un cambio de actitud en el alumnado, desde el entusiasmo y la ilusión inicial al desencanto y rechazo absoluto hacia la Escuela en los últimos años. 

El proceso de la elaboración de los códices "Borgia" y "Vaticano B" basado en su estudio codicológico

El objetivo de este artículo es presentar las observaciones realizadas durante la consulta de los originales de los códices Borgia (Borg. Mess. 1) y Vaticano B (Vat. Lat. 3773) en la Biblioteca Apostólica Vaticana en 2014. Este estudio codicológico, aunque a la fuerza parcial, dado que fue realizado solamente por medio de una observación directa, revela nuevos datos acerca de la elaboración de los manuscritos prehispánicos, tanto en la preparación de la piel como soporte como en los procedimientos aplicados a la hora de trazar las imágenes y corregir las equivocaciones.

Moviendo montañas: empresas, comunidades y ONG en las industrias extractivas

El actual auge de las industrias extractivas ha estado acompañado de un considerable debate público acerca de los impactos sociales y ambientales que generan estas actividades, así como también del papel que les corresponde desempeñar en el desarrollo local y nacional. En este debate destaca el nuevo protagonismo de las organizaciones de la sociedad civil –locales, nacionales y transnacionales-, que buscan fiscalizar el desempeño socio-ambiental de las empresas y lograr una redistribución de las rentas y oportunidades que generan. Los tres estudios de caso presentados en este libro –Compañía Minera Antamina, Asociación Civil Labor y Cementos Lima S.A.- demuestran los nuevos retos que enfrentan las empresas extractivas, las ONG que vigilan sus actividades y las comunidades afectadas por ellas. El libro busca difundir los hallazgos obtenidos en el estudio de estas tres experiencias y extraer lecciones relevantes para los diversos actores en este drama.
