Entre salinas e maledicências: uma leitura do romance Macau e sua aplicabilidade ao ensino de literatura

The objective of this research is to present a reading of the novel Macau (1934), authoring of Aurélio Pinheiro, situated in the context of Brazilian literature produced in the 30s of the last century and analyze the settings of language that reveal individual and social conflicts related to tensions arising of the modernization of a city in the interior of Rio Grande do Norte, in view of the applicability of this knowledge in the educational context. The discussions on the teaching of literature led to an internship experience in the higher education, with the guiding literary reading of the novel Macau. In this sense, this research, bibliographic, analytical and empirical, is in discussions between literature and education that allow us, in addition to a critical reading about Macau romance, a look both in basic education and in teacher training, which justifies linking this thesis in the research line “Reading of the literary text and teaching”. The objectives were met from literary readings of the text, brief study of the author, analysis of the tensions expressed by language, literature defense as a universal right, panoramic review of research on the teaching of literature, reading official documents governing the Brazilian education, discussion of teacher training, training in higher education with application of a didactic sequence, receipt of that novel by teachers in training directed to the applicability in basic education. For this, the research was the theoretical framework primarily the studies of Antonio Candido (1976; 1995), Luís Bueno (2006), Walter Benjamin (1985), Mikhail Bakhtin (2010), Hans Robert Jauss (1994), Theodor Adorno (2006), Antoine Compagnon (2009), and Rildo Cosson (2009).

Para uma gestão social no programa minha casa, minha vida: reflexões acerca da organização comunitária em empreendimentos da faixa 1

A política habitacional teve importante avanço na década de 2000, principalmente com a criação do Ministério das Cidades. A estruturação do Plano Nacional de Habitação ocasionou inclusão do tema na agenda governamental, permitindo a produção de habitação de interesse social voltada à população em situação vulnerável, através do Programa Minha Casa Minha Vida (PMCMV). Assim, a presente dissertação tem como objetivo compreender atributos de gestão social para a organização comunitária em empreendimentos da faixa 1 do Programa. Para tanto, realizou-se pesquisa quantitativa, por meio da aplicação de formulários, e qualitativa, por meio de grupo focal, ambos com beneficiários do Programa. No tocante aos resultados, observou-se debilidade do papel do Estado, caracterizado principalmente pelos frágeis Projetos Técnicos de Trabalho Social. Os elementos de gestão social igualmente foram frágeis, distanciando os empreendimentos de condições ideias de habitabilidade e convívio coletivo. A ausência de compreensão da relevância de bem-estar coletivo e a precariedade da esfera pública, conduzem ao afastamento da finalidade emancipatória da gestão social. Destacou-se, ainda, o papel de associações de moradores e de iniciativas de trabalho coletivo no atendimento de demandas sociais da comunidade.

Caracterização citoarquitetônica e por imunoistoquímica para tirosina-hidroxilase da substância negra, área tegmentar ventral e zona retrorubral do Sagui (Callithrix jacchus)

It is known that the catecholamine group is constituted by dopamine, noradrenaline and adrenaline, in which the synthesis is regulated by an enzyme named tyrosine hydroxylase. Thus, 3-hydroxytyramine/dopamine (DA) is a precursor of the noradrenaline and adrenaline synthesis and acts as a neurotransmitter in the central nervous system. The three main nuclei, named the retrorubral field (A8 group), the substantia nigra pars compacta (A9 group) and the ventral tegmental area (A10 group), are arranged in the die-mesencephalic portion and are involved in three complexes circuitries - the mesostriatal, mesolimbic and mesocortical pathways. These pathways are related to behavioral manifestations, motricity, learning, reward and pathologies such as Parkinson’s Disease and Schizophrenia. Thus, the aim of this study was to perform de morphological analysis of the A8, A9 and A10 nuclei of the common marmoset (Callithrix jacchus). The marmoset is a neotropical primate, whose morphological and functional characteristics supports the suitability of use of this animal in biomedical research. Coronal sections of the marmoset brain were submitted to cytoarchitectonic characterization and TH-immunohistochemistry. Based on the morphology of the neurons, it was possible to subdivide the A10 group in seven regions: interfascicular nucleus, raphe rostral linear nucleus and raphe caudal linear nucleus, in the middle line; paranigral and parainterfascicular nucleus, in the middle zone; rostral portion of the ventral tegmental area nucleus and parabrachial pigmented nucleus, located in the dorsolateral portion of the mesencephalic tegmentum. A9 group was divided into four regions: substantia nigra compacta dorsal and ventral tiers; substantia nigra compacta lateral and medial clusters. No subdivisions were founded into A8 group. These results revealed that A8, A9 and A10 are phylogenetically conserved between species, but it’s necessary to expand the studies about this compartmentalization, investigating its occurrence in other primate species or investigating its functional relevance.

Distribuição e uso de habitat por peixes recifais em um gradiente ambiental: estudo de caso em recifes areníticos

There are several abiotic factors reported in the literature as regulators of the distribution of fish species in marine environments. Among them stand out structural complexity of habitat, benthic composition, depth and distance from the coast are usually reported as positive influencers in the diversity of difentes species, including reef fish. These are dominant elements in reef systems and considered high ecological and socioeconomic importance. Understanding how the above factors influence the distribution and habitat use of reef fish communities are important for their management and conservation. Thus, this study aims to evaluate the influence of these variables on the community of reef fishes along an environmental gradient of depth and distance from shore base in sandstone reefs in the coast of state of Rio Grande do Norte, Brazil. These variables are also used for creating a simple predictive model reef fish biomass for the environment studied. Data collection was performed through visual surveys in situ, and recorded environmental data (structural complexity of habitat, type of coverage of the substrate, benthic invertebrates) and ecological (wealth, abundance and reef fish size classes). As a complement, information on the diet were raised through literature and the biomass was estimated from the length-weight relationship of each species. Overall, the reefs showed a low coverage by corals and the Shallow reefs, Intermediate I and II dominated by algae and the Funds by algae and sponges. The complexity has increased along the gradient and positively influenced the species richness and abundance. Both attributes influenced in the structure of the reef fish community, increasing the richness, abundance and biomass of fish as well as differentiating the trophic structure of the community along the depth gradient and distance from the coast. Distribution and use of habitat by recifas fish was associated with food availability. The predictor model identified depth, roughness and coverage for foliose algae, calcareous algae and soft corals as the most significant variables influencing in the biomass of reef fish. In short, the description and understanding of these patterns are important steps to elucidate the ecological processes. In this sense, our approach provides a new understanding of the structure of the reef fish community of Rio Grande do Norte, allowing understand a part of a whole and assist future monitoring actions, evaluation, management and conservation of these and other reefs of Brazil.

Validade científica de conhecimento epidemiológico gerado com base no estudo Saúde Bucal Brasil 2003

Indicators and analyses that used the database from SB Brazil 2003 (the most recent nationwide oral health survey) have been criticized as unreliable due to sampling problems. The current study countered that this critique was based solely on statistical concepts, unsupported by empirical evidence. The critique's essentially epistemic approach leads to peremptory reductionism that denies other forms of knowledge and fails to recognize the multidisciplinary nature of epidemiology. The current study retrieves information on the implementation of the oral health survey and its impact on knowledge output in the field. The article draws an analogy between science and art, demonstrating the multifaceted images obtained by both. Thus, recognition of validity requires a full grasp of the field and appropriate use of value criteria. The current article concludes that use of the SB Brazil 2003 database is a reliable and relevant application of epidemiology to oral health.

Crescimento urbano e seus impactos no sistema de drenagem de uma bacia em Natal/RN

The uncontrolled growth of most Brazilian cities is not accompanied by the development of urban infrastructure. With increasing soil sealing, runoff and decreased infiltration volume, impacts on water resources and on population of the areas affected by urban growth are inevitable. This study aims to evaluate the use and occupation of a watershed and analyze the drainage system in order to control the impact using tools to integrate urban development with the drainage of rainwater in an important watershed in the Natal City, Rio Grande do Norte State. The study involved the characterization of the basin XII.4 on the land use and occupation, for the years 2005 and 2014. With the application of SWMM model was possible to analyze the impacts caused by the urbanization process in the existing drainage system, showing the two years analyzed have their areas very close to percentage saturation of impervious areas. Although the region is still predominantly single family residential, suffers increasing verticalization of mainly commercial buildings. The drainage system is inefficient for the area's needs by the year 2005. The drainage system was also tested for four variations of land use by developing scenarios. Scenario 1 is related to the year 2014, considered current. Scenario 2 was adopted the maximum rate of 80% for land use, allowed for the Natal City. Scenario 3 gives the critical condition of land use, with the area 100% impervious. Scenario 4 is applied to the existence of LID (Low Impact Device). The scenarios analysis showed that all indicate deficiency at some point of the drainage system as a result of the high degree of occupation of the area that generate higher flows than the initial drainage system capacity. With the study it became clear that the adoption of non-structural tools are effective in reducing flooding and improving the drainage system capacity.

A produção textual no ensino fundamental: processo de retextualização com o gênero memórias

Teaching Portuguese language in Brazilian public schools is still limited mostly to studying decontextualized text fragments, memorizing classifications and cult of grammar rules. Considering the language as a social, cultural practice which emerges from the intersubjective interaction, we sought to propose an educational intervention that prioritizes the retextualization processes from speech to the writing of memoirs as a textual genre, so as to contribute for improving learner’s discursive performances. Therefore, paying attention to these concerns and in attempt to contribute for improving the teaching of Portuguese language in elementary school, we chose as privileged locus a 9th grade class from a state school in Bento Fernandes, RN. The corpus is formed by texts produced and retextualized by students from the elders’ oral reports within local community. We sought thus to understand what memory is, its importance for registering local spoken language and culture, as much as to carry out didactic actions that favor students’ learning in the activities of textual production. In light of the theoretical overviews about linguistic-discursive relations, based on Marcuschi’s (1993, 1997, 2001, 2002, 2006, 2008, 2010) conception of oralitiy-writing continuum and the debates proposed by Antunes (2003, 2014), Alves Filho (2011), Koch (2012) and Bakhtin (1992, 2011), we aimed to understand, by analyzing the retextualized memoirs, how these practices complement each other within the process of orality and writing. As for the proposal of didactic sequences, the study has been oriented by Dolz and Scheneuely (2004); as for the memoirs, by the guidelines of Coracine and Ghiraldelo (2011) and Le Goff (2010, 2013). In this way, this work followed the action-research methodology in a qualitative approach, considering the teacher (researcher) as an active agent involved in the process of knowledge production in his own educational practice, so as to interfere in the mediation, knowledge production and its dissemination in classroom context, which is the privileged locus for constructing and transforming process. There is much to be research within the area of retextualization. Yet we verified that this educational intervention, based on discursive operators of retextualization, has been proven viable as an efficient path so that we teachers can work the peculiarities of usages and functions of textual genres in oral and written modalities of a language, without grasping both as a dichotomy. This accredited us to strengthen a discourse that undoes many myths still present in that order, especially the one that causes more damage for the learners of Portuguese language – that writing is a representation of speech.

Interações magnéticas e elétricas em GaMnAs

In this paper, we will address together the magnetic and electrical properties of a particular semiconductor, the GaMnAs. The treatment will be done analytically in the first part of the work, according to the computational method for simulation of physical systems through the implementation of the expressions obtained in the first part. All study of magnetic contribution will be made using an interaction Kondo type, using an approach by Green functions. The electrical part, which consists of the Coulomb interactions between carriers and Mn ions, will be treated within the approach of multiple scattering. The implementation of the proposed method will calculate the Green functions converged as multiple scattering solution and use them as a starting point for the calculation of the effective magnetic interactions between Mn ions mediated charge carriers. The concentration parameters were varied for Mn ions and carriers as well. The combination of these two parameters can lead to insulating, metal samples with carriers in Fermi level to low or high mobility. As a result a correlation between the obtained carrier mobility and the strength of magnetic interaction. The greater mobility, the greater the intensity of the interaction.

O uso da Divergência de Kullback-Leibler e da Divergência Generalizada como medida de similaridade em sistemas CBIR

The content-based image retrieval is important for various purposes like disease diagnoses from computerized tomography, for example. The relevance, social and economic of image retrieval systems has created the necessity of its improvement. Within this context, the content-based image retrieval systems are composed of two stages, the feature extraction and similarity measurement. The stage of similarity is still a challenge due to the wide variety of similarity measurement functions, which can be combined with the different techniques present in the recovery process and return results that aren’t always the most satisfactory. The most common functions used to measure the similarity are the Euclidean and Cosine, but some researchers have noted some limitations in these functions conventional proximity, in the step of search by similarity. For that reason, the Bregman divergences (Kullback Leibler and I-Generalized) have attracted the attention of researchers, due to its flexibility in the similarity analysis. Thus, the aim of this research was to conduct a comparative study over the use of Bregman divergences in relation the Euclidean and Cosine functions, in the step similarity of content-based image retrieval, checking the advantages and disadvantages of each function. For this, it was created a content-based image retrieval system in two stages: offline and online, using approaches BSM, FISM, BoVW and BoVW-SPM. With this system was created three groups of experiments using databases: Caltech101, Oxford and UK-bench. The performance of content-based image retrieval system using the different functions of similarity was tested through of evaluation measures: Mean Average Precision, normalized Discounted Cumulative Gain, precision at k, precision x recall. Finally, this study shows that the use of Bregman divergences (Kullback Leibler and Generalized) obtains better results than the Euclidean and Cosine measures with significant gains for content-based image retrieval.

Algorithms for super-resolution of images based on Sparse Representation and Manifolds

lmage super-resolution is defined as a class of techniques that enhance the spatial resolution of images. Super-resolution methods can be subdivided in single and multi image methods. This thesis focuses on developing algorithms based on mathematical theories for single image super­ resolution problems. lndeed, in arder to estimate an output image, we adopta mixed approach: i.e., we use both a dictionary of patches with sparsity constraints (typical of learning-based methods) and regularization terms (typical of reconstruction-based methods). Although the existing methods already per- form well, they do not take into account the geometry of the data to: regularize the solution, cluster data samples (samples are often clustered using algorithms with the Euclidean distance as a dissimilarity metric), learn dictionaries (they are often learned using PCA or K-SVD). Thus, state-of-the-art methods still suffer from shortcomings. In this work, we proposed three new methods to overcome these deficiencies. First, we developed SE-ASDS (a structure tensor based regularization term) in arder to improve the sharpness of edges. SE-ASDS achieves much better results than many state-of-the- art algorithms. Then, we proposed AGNN and GOC algorithms for determining a local subset of training samples from which a good local model can be computed for recon- structing a given input test sample, where we take into account the underlying geometry of the data. AGNN and GOC methods outperform spectral clustering, soft clustering, and geodesic distance based subset selection in most settings. Next, we proposed aSOB strategy which takes into account the geometry of the data and the dictionary size. The aSOB strategy outperforms both PCA and PGA methods. Finally, we combine all our methods in a unique algorithm, named G2SR. Our proposed G2SR algorithm shows better visual and quantitative results when compared to the results of state-of-the-art methods.

Ampliação vocabular: glossário de textos do livro didático de língua portuguesa "Vontade de saber português" do 9º ano

This research aimed to verify the vocabulary difficulties faced by 9th year students while understanding the didactic book of Portuguese Language (DBPL) “Vontade de Saber Português”, used at the Municipal School Sebastião Rangel. We noticed the students had some doubts concerning the unknown vocabulary in the texts and, therefore, in text comprehension. The hypothesis is that one “difficult” word and the lexicon used by DBPL author can disturb student comprehension. We adopted some action which could simplify the little vocabulary understanding and contributed to extend it. For that reason, the job was theoretically based on Biderman (1999), Barbosa (1989), Dias (2004), Krieger (2012), Coelho (1993) and on National Curriculum Parameters of Portuguese Language, aiming to ally theory and practice. The application methodology of the proposal was done in order to the students understand that the word needs to be adapted to its context. At the begging of the job, the students read the texts and took notes of the “difficult” words, selecting, corpus. We analyzed the doubts, registering them. Then, we showed to the students the classification of abbreviated words after each entry. The students separated the words for grammar classes – lexical words” (KRIEGER, 2012). Such words have a very significant meaning to the comprehension of the read texts, being interesting to take a look in online dictionaries. In the creative glossary, done by the students, the words were spread in alphabetical order. They transcript the part where was the word and copied again, substituting the word to a clearer word. Finally, we asked the students a writing production using five words from the glossary; we showed them that the meaning of the words is not found only in the dictionary, but they can be used in different contexts. In the analyzes, was discovered that there is one necessity of a pedagogic didactic work more effective with elementary school lexicon. Thus, this proposal is not a closed receipt, but the infield location allowed a reflexive pedagogic practice about lexicon education.

"Lancea", Lusitanian Word, and the "Lancienses" Ethnogenesis

Analysis of the word lancea, of Hispanic origin after Varro, and of place names, people´s names and personal names derived from it. It confirms that the spear was the most important weapon in the Bronze Age, belonging to the iuventus and used as heroic and divine symbol. This analysis confirms also the personality of the Lusitanians, a people related to the Celts but with more archaic archaeological, linguistic and cultural characteristics originated in the tradition of the Atlantic Bronze in the II millennium BC. It is also relevant to better know the organisation of Broze and Iron Age societies and the origin of Indo-Europeans peoples in Western Europe and of pre-Roman peoples of Iberia.
