Aprender e ensinar na escola inclusiva: desafios na construção da identidade de pedagogos

The democratization of Brazilian education and discussion about the educational rights of persons with disabilities in refer to reflection on the conceptions of teaching and learning and the folding of these concepts in practice and in the formation of professional identity of the teacher educator. Thus, the proposed research in this dissertation aimed to describe educational processes developed by educators in classrooms in which they are enrolled students with disabilities a view to considering how these processes affect the construction of their professional identity of the pedagogue. As the methodology used to research is classified as Case Study. This methodological approach enables the analysis of singularities of educational contexts. In this work, the case investigated consisted of the analytical study of the pedagogical practices developed in classrooms where there are students with disabilities and their relation to the establishment of the professional identity of the teacher in a school linked to a non-governmental organization supporting people with disabilities in the city of Natal / RN. The Data were collected through the use of the following instruments: exploratory questionnaires, observation and respective registration in the field diary of research and interviews with educators in different professional cycles proposed by Huberman. The data reveal didactic and pedagogical aspects common in educational processes in the observed classes and differences concerning the specifics of pedagogues in the teaching profession in different moments of their professional careers. The analysis of the conceptions tell us the nuances of meanings constructed on teaching and learning and its interface with the reflection on teaching practice. As to the meaning assigned to be pedagogue research highlights the professional identification related to the meanings of teaching and learning in school. The experiences in the teaching profession according to the survey data point to changes in teachers conceptions about teaching and learning disabled people in the perspective of inclusion. Therefore, the study concludes that the pedagogical practices with students with disabilities the different experiences add up and can transform conceptions of teachers about teaching and learning interfering with constant reflection on practices and the construction of professional identities of pedagogues.

Território para viver: dinâmicas territoriais da comunidade quilombola de Acauã, Poço Branco, Rio Grande do Norte

In the late 1980s, the quilombola (or maroon) communities emerged on the Brazilian public scene. They established themselves as new collective subjects and ethnic groups, in a historical moment of sensitive political changes in several social conflicts and struggles, both in Brazil and in Latin America. Because of their socio-cultural and historical singularities, these communities have self-identified in the same collective expression and have organized in search of recognition and respect for their rights. Quilombo communities and other self-labeled as "traditional communities" seek to reaffirm their differences in opposition to a conscious colonizer cultural project and re-signify their memories and traditions, that serve as reference in the construction of alternative production projects and community organization. One of the distinguishing characteristics of this quilombola political emergence process is the territorial nature of the struggles, manifested in at least two directions: on the one hand, the struggle for legal and formal recognition of a given space, i.e., the regularization and titling of occupied territories, considering that the Brazilian Constitution of 1988 recognizes the right of these communities to the final possession of the traditional lands. On the other hand, the struggle for recognition of their territoriality in a broader sense, not necessarily restricted to the demarcated area, but as the recognition of a culture and its own way of life, that originated historically in these territories. The current accomplishments and challenges of the Brazilian quilombola communities are well exemplified by the quilombo of Acauã, in the Poço Branco municipality of Rio Grande do Norte. The last fifteen years have been marked by important changes in this community, which has gained visibility and has emerged as a new political player. Acauã identified itself as quilombola community in 2004, the same year that it formalized its political structure, through the creation of the Association of Residents of Quilombo Acauã (AMQA, in Portuguese). Also in 2004, it requested to the National Institute of Colonization and Land Reform (INCRA, in Portuguese) the opening of the process for regularization and titling of quilombo territory, which is at an advanced stage, but so far without definitive resolution. This study aims to understand the process of territorialization (struggle for territorial claim) played in the last fifteen years by the community of Acauã.

Ensino e aprendizagem de violão na UFRN

The instrumental teaching in Brazil has been more widely studied by music education in the last years, becoming a significative scientific investigation field. This work is focusing on analysis of the instrument teaching reality, considering more specifically the guitar teaching. In a timely manner, approaches the reality of the guitar teaching from the Universidade Federal do Rio Grande do Norte (Federal University of Rio Grande do Norte – UFRN), considering specific instrument courses in this institution. Thus, the present work was guided by the aim of understanding conceptions, contents and didactic and methodological perspectives that constitute the teaching and learning of the guitar at UFRN. To reach this main aim, we sought to verify, in general: 1) the theoretical, methodological and content perspectives that underlie guitar formation in the music courses of the UFRN; 2) the functions and the aims of the guitar disciplines in the Courses; 3) the profile of the guitar disciplines' professors; 4) the demands of the subjects directly involved in these proposals of musical education; and, 5) the conceptions about formation practices and teaching methodologies that characterize the docent action. In accordance with the aims, the methodological guidance was based on the qualitative paradigm. Thus, data collection procedures involved were: bibliographical and documentary research and interviews with three professors who taught in guitar disciplines during the semester of 2014.1 on the mentioned courses. Then, these data were systematically organized and analyzed in line with the research characteristics presented here. The results of the research evidenced the concepts, contents and didactic and methodological perspectives in the context of teaching and learning guitar in the studied empirical field. In this context, we perceive a relation between the demands of teaching and learning tool in the study field and the ones evidenced in the literature. The results demonstrated that the professors’ professional tragetory is associated with their influences from the initial musical formation and their guitar learning since they related conceptions that reflected aspects formation, sometimes converging sometimes divergente. The contentes, methodologies and general aspects are made based on parameters that demonstrate alignment with the perspectives of guitar teaching and learning in the contemporary world to the instrumental player formation. Thus, the study gave a broader diagnosis about the guitar teaching reality, demonstrating the diferences and the singularities between the Technical Course and the Course of Bachelor in Music at UFRN. Thereby, this study provides importante contribution to music education, mainly, through its reflections about the guitar pedagogy.

Práticas e características do jornalismo alternativo e contra hegemônico de agência de informação: uma visão a partir da rotina produtiva da Adital

The strong presence of the communication and information technologies (TICs) forced the productive routine of some media vehicles to go through significant changes. The same happened to the alternative agencies segment. Having a scarce literature and sources about this subject, this study’s objective is to understand how the Information Agency Frei Tito for Latin America (Adital) develops its proposal of alternative journalism, within the cyberspace, while aiming a Christian communication. For this finality, the study will describe and explain the practices of journalistic production, identifying the subjects involved and the relations maintained between them in this productive routine. Also, it will trace who and where these content replicators are and/or their online address. At first, it was presented a theoretical discussion about the concepts of “counter-hegemony”, alternative journalism and communicative citizenship, what brings us to the studies of Gramsci (2010), Peruzzo (2011), Moraes (2013), Paiva (2008), Coutinho (2008), Mata (2006), among other authors. Next, it will be approached briefly the historical path of the information agencies around the world and in Latin America, so that the study can focus on authors like Aguiar (2009), Pasti (2013) and Moraes (2010). This piece will draught a “methodologic route” for a qualitative approach with an exploratory and descriptive character. We gave up the etnometodological methods, what allow us to analyze the etnomethods or behavioral groups of action, procedures, activities and knowledge that constitutes these groups, giving them recognition and distinction. (COULON, 1995). To achieve the defined objectives, it was also used a bibliographical and documental research techniques, in addition to subject observation and semi-structured interviews. Finally, we analyze the collected data taking into consideration three pivots: the beginning of Adital; the practices, characteristics and subjects involved in the productive routine of the agency; and who are and where are these content replicators of content produced and transmitted by Adital. We can conclude that the production routine of an alternative agency and the counter-hegemonic of information is marked by some singularities regarding to the organization of the journalistic practice and to the obstacles found on the way. Our data allows us, even if there are still some doubts, to believe that Adital is a sort of independent information agency, alternative and counter-hegemonic, ergo, more close to a proposition of communicative citizenship.

Polarization tailored novel vector beams based on conical refraction

Coherent vector beams with involved states of polarization (SOP) are widespread in the literature, having applications in laser processing, super-resolution imaging and particle trapping. We report novel vector beams obtained by transforming a Gaussian beam passing through a biaxial crystal, by means of the conical refraction phenomenon. We analyze both experimentally and theoretically the SOP of the different vector beams generated and demonstrate that the SOP of the input beam can be used to control both the shape and the SOP of the transformed beam. We also identify polarization singularities of such beams for the first time and demonstrate their control by the SOP of the input beam.

Degeneracy of velocity constraints in rigid body systems

The equations governing the dynamics of rigid body systems with velocity constraints are singular at degenerate configurations in the constraint distribution. In this report, we describe the causes of singularities in the constraint distribution of interconnected rigid body systems with smooth configuration manifolds. A convention of defining primary velocity constraints in terms of orthogonal complements of one-dimensional subspaces is introduced. Using this convention, linear maps are defined and used to describe the space of allowable velocities of a rigid body. Through the definition of these maps, we present a condition for non-degeneracy of velocity constraints in terms of the one dimensional subspaces defining the primary velocity constraints. A method for defining the constraint subspace and distribution in terms of linear maps is presented. Using these maps, the constraint distribution is shown to be singular at configuration where there is an increase in its dimension.

“Yo acojo, tú agrupas, ella compensa”: Análisis comparado de la política de integración del alumnado inmigrante en tres Comunidades Autónomas

Con la Ley Orgánica de Mejora de la Calidad Educativa vuelve a emerger uno de los temas educativos más oportunos: la toma de decisiones en torno a las políticas educativas de atención al alumnado inmigrante. El momento supone una excelente excusa para, desde el prisma que nos ofrece la Educación Comparada, revisar cómo el colectivo de infancia inmigrante ha sido educado desde tres modelos de gestión educativa representados por tres Comunidades Autónomas: Comunidad Valenciana, Cataluña y Andalucía. El artículo se sitúa en el análisis de las medidas que se han articulado en los tres casos como respuesta a su recepción, acogida y escolarización, utilizando una metodología cualitativa basada en el método comparado: en el estudio descriptivo (fase analítica), se realiza una exploración explicativa de las medidas articuladas en torno a las políticas de gestión del alumnado inmigrante, mediante el análisis de contenido de fuentes primarias y secundarias. Con respecto a los resultados, en la fase sintética, tras haber yuxtapuesto los principales criterios que asemejan y también dirimen a los tres modelos, se reconoce cómo las tres Comunidades Autónomas presentan particularidades, fruto de trayectos históricos propios, coyunturas económicas y políticas e intenciones educativas y sociales, influidas por contextos en los que algunos factores han tenido un peso específico importante. Además del protagonismo institucional, se detectan diferencias notables en las medidas concretas adoptadas, pero también coincidencias, como las políticas que apoyan económicamente la lengua de la comunidad autónoma. Finalmente, en la fase de conclusiones comparadas, se plantean una serie de elementos de los que se deberían dotar las Comunidades Autónomas y que se hallan presentes en algunos modelos analizados. La atención a la lengua que porta el alumnado o el cuidado por incluir una educación intercultural en los planes de los centros educativos son dos de las acciones más significativas.

Sasakian quiver gauge theories and instantons on cones over lens 5-spaces

We consider SU(3)-equivariant dimensional reduction of Yang Mills theory over certain cyclic orbifolds of the 5-sphere which are Sasaki-Einstein manifolds. We obtain new quiver gauge theories extending those induced via reduction over the leaf spaces of the characteristic foliation of the Sasaki-Einstein structure, which are projective planes. We describe the Higgs branches of these quiver gauge theories as moduli spaces of spherically symmetric instantons which are SU(3)-equivariant solutions to the Hermitian Yang-Mills equations on the associated Calabi-Yau cones, and further compare them to moduli spaces of translationally-invariant instantons on the cones. We provide an explicit unified construction of these moduli spaces as Kahler quotients and show that they have the same cyclic orbifold singularities as the cones over the lens 5-spaces.

Paisagem, um patrimônio esquecido: subsídios para a construção de uma metodologia de valoração e proteção do cenário natural litorâneo

The so-called "residential tourism" came to intensify the previous occupation of the coastal zones, characterized by traditional beach houses, and brought significant consequences for their spatial configuration, and especially for its scenic value of the landscape. Although there is the intention to regulate the activities of enterprising groups by some legal instruments to control the use and occupation of land, and to contain some negative effects, the actions of government are still inefficient in trying to follow the implications on the landscape from the accelerated growth of the real estate and touristic sectors. Supported in the speech of economic development and income generation, public managers prioritize areas to attract tourists to the detriment of preserving important physical attributes of the natural environment that contribute significantly to the quality of life. The result can be noticed in the use of natural elements as one of the major components in the land valorization, and in the immediate attraction of investors and enterprising. Therefore, the objective of this work is to contribute to the debate on the landscape preservation a little detailed thematic in view of their relevance in the current context - by indicating subsidies to the creation of a methodology for the evaluation and protection of coastal zones that may assist the government in creating new instruments, and better prepare it in control of the occupation of these areas. For such, was followed two ways to analysis: the indirect method and the direct method. The first is grounded in the evaluation of landscape attributes, which is based on the work of Raquel Tardin (2008) and Eduardo Cuesta, Encarnación Algarra and Isabel Pastor (2001). The second, based on the research of Leticia and Carlos Hardt (2010) and on the concepts of phenomenology - expressed by Antonio Christofoletti (1985) and Yi-Fu Tuan (1983) - considers the population perspective on the quality of the natural scenery. Developed through cartographic materials, photographic collections and quantitative tables, this dissertation utilized as a case study the beaches of Barra de Tabatinga and Camurupim, located in the city of Nísia Floresta/RN. Despite already being sighted spaces of advanced stage of landscape degradation in these locations, areas of remarkable scenic value can still be found, what reinforce the urgency in adopting preservationists actions. The absence of laws focused on the management and protection of the landscape singularities associated with the inefficiency of the government to invigilate the land occupation in coastal zones, encourage the excessive action of the real estate-tourism, and consequently make the government the main responsible for the environmental and landscape impacts in these areas - by its omission or by their connivance. Therefore, the legislation permeates this entire process and constitutes itself as the most effective way to guarantee the right to the landscape to present and future generations. Are also pointed some important considerations to build a methodology, especially concerning possibilities of improvements and adaptations of its applicability in each case

Da colônia ao shopping: um estudo da evolução tipológica da arquitetura hospitalar em Natal

A conceptual discussion on architectural type and its role in theory and practice supports the construction of an analytical tool used for recognizing the typological evolution of hospital architecture in Western societies. The same tool is applied to analyze the typological evolution of hospital architecture in Natal, Brazil, through a sample of eighteen hospitals built in the city since the beginnings of 20th century. The conclusion is that typological evolution in Natal is almost the same as occidental one, except for a few singularities that can be explained by local social and economic development

Strong quantum memory at resonant Fermi edges revealed by shot noise

Studies of non-equilibrium current fluctuations enable assessing correlations involved in quantum transport through nanoscale conductors. They provide additional information to the mean current on charge statistics and the presence of coherence, dissipation, disorder, or entanglement. Shot noise, being a temporal integral of the current autocorrelation function, reveals dynamical information. In particular, it detects presence of non-Markovian dynamics, i.e., memory, within open systems, which has been subject of many current theoretical studies. We report on low-temperature shot noise measurements of electronic transport through InAs quantum dots in the Fermi-edge singularity regime and show that it exhibits strong memory effects caused by quantum correlations between the dot and fermionic reservoirs. Our work, apart from addressing noise in archetypical strongly correlated system of prime interest, discloses generic quantum dynamical mechanism occurring at interacting resonant Fermi edges.

Superlattice structures in twisted bilayers of folded graphene

The electronic properties of bilayer graphene strongly depend on relative orientation of the two atomic lattices. Whereas Bernal-stacked graphene is most commonly studied, a rotational mismatch between layers opens up a whole new field of rich physics, especially at small interlayer twist. Here we report on magnetotransport measurements on twisted graphene bilayers, prepared by folding of single layers. These reveal a strong dependence on the twist angle, which can be estimated by means of sample geometry. At small rotation, superlattices with a wavelength in the order of 10 nm arise and are observed by friction atomic force microscopy. Magnetotransport measurements in this small-angle regime show the formation of satellite Landau fans. These are attributed to additional Dirac singularities in the band structure and discussed with respect to the wide range of interlayer coupling models.
