Um divagar pouco atraente: o tema das raças em Os Sertões de Euclides da Cunha

Os Sertões of Euclides da Cunha is one of the most studied books of Brazilian social thought, with approaches ranging from literature to geology, mobilizing concepts and theoretical and disciplinary perspectives the most diverse. This work aims to identify the process of building the concept of race by Euclides da Cunha in this work. To achieve this goal, will be studied, at first, the process of intellectual and political formation of Euclides da Cunha in the years prior to his trip to Canudos, in order to identify the presence of themes and authors in their thinking, using for this purpose, as the main source, your correspondence and press articles, which are expressed in the basic references of his training and dialogue on topics and authors that permeated their way of thinking about the Brazilian reality in the late nineteenth century and early twentieth century. In the second stage of labor, with reference to the study of the presence of several theories that explain human behavior from racial lines, with a strong Brazilian influence in the intellectual environment of the late nineteenth century, an analytical effort will be made in order to understand the synthesis made specific by Euclides da Cunha in the preparation of his work, to identify the main authors based their thinking on this aspect of the changes in your way of thinking about the man of the interior in an attempt to understand how the concept this race is in the interpretation of the conflict happened in Canudos and action of some of her protagonists

Afinal, quantos éramos? Um estudo da mortalidade pretérita na freguesia da gloriosa Sant Anna

Search mortality in the glorious St. Anna Parish, hinterland of Rio Grande do Norte in the time frame 1788-1838 is the main objective of this research. Questions that the research aims to answer are: how many were after? Data parish deaths allow us to study mortality in Town? To conduct the research, first appealed to the population maps of the years 1777, 1810, 1811, 1824, 1844, 1853; censuses of 1872 and 1890. As well, the first two books of burials / deaths of the Parish, the first dating from 1788 to 1811 and the second from 1812 to 1838 and a book of baptism 1803-1806. Among the findings it was realized that, for now, the question of knowing, "After all, how many were?" Still cannot be answered, because during the analysis we noticed a high rate of underreporting, demonstrated through a study of the first infant mortality, in which the records we have was very high, which goes against the pre-transitional period, but with the exercise of inverse projection found the opposite, a population that would have a life expectancy higher. Demonstrating the problem of underreporting. Infant deaths occur mainly with the male children in the first months of the year due to infectious causes, and in the early days and weeks, we raised a hypothesis is that these deaths have as a backdrop the poor condition of the mother leading to poor training child, thus leading to his early death

Podem os programas sociais e de transferência de renda influenciar a oferta de trabalho em atividades não agrícolas? uma análise para as famílias em condição de pobreza no meio rural do nordeste

This study aims to analyze the main effect of social programs and cash transfers on the labor supply of non-farm family members in poverty in rural areas of the Northeast. Among the specific objectives, we sought to investigate the effects of these programs and individual characteristics on the decision of participation and allocation of working hours of parents and children in non-agricultural activities. It was assumed, as a theoretical basis, the model of neoclassical labor supply as well as the principle that the decision of allocation of working hours, non-agricultural, is subject to the initial choice of the worker devote or not the non-agricultural employment . The hypothesis assumes that access to social programs and income transfer contributes to the dismay of rural workers, in poverty, in its decision to participate and offer hours of work in non-agricultural activities. To achieve this objective, we applied the models of Heckman (1979) and Double Hurdle, of Cragg (1971), consisting of associating the decision to participate in the labor market with the decision on the amount of hours allocated. The database used was the National Survey by Household Sampling (PNAD) of 2006. The results of the heads of households showed that transfers of income, although they may have some effect on labor supply rural nonfarm, the magnitude has to say that there may be some dependence on benefits. The estimates for the joint children of 10 to 15 years showed that the programs have negatively influenced participation in suggesting an increase in school participation, although for the allocation of working hours the results were not significant on the incidence of child labor

A prática docente de Myriam Coeli na década de 1960

The present work has as objective to reconstitute the biographical profile and pedagogical practices of the teacher Myriam Coeli de Araújo Dantas da Silveira, in the Professionalizing scholl of the Federal Net of the Rio Grande do Norte, in the 60 s years. The choice of the period is justified by being this the time of important changes in the Education, as an example we have the implementation of the Law of Lines of direction and Bases of the National Education, the 4.024/1961. This teacher contributed for the formation of the potiguar s society scholar, acting in the press, the journalism and the teaching, activity that I analyzed in this study. How the pedagogical practices of her had happened in the 60 s years? This question guided the research and, in the search to answer it I used as source the Public Archive of the Rio grande do Norte, the Historical and Geographic Institute of the Rio grande do Norte, the periodicals of the time, photographs, sketch books of Myriam Coeli and interviews with familiar, former-pupils and contemporaries of this master. I verified that her performance always was based in the educational changes lived deeply for her, carrying through a series of activities in the school as: elaboration of the annual program of Portuguese Language, organization of literary competitions and an practice based on the effective norms without leaving to unite respect and the understanding for the pupils. Of this form, the analysis is not summarized only to the practices of a teacher, but the configuration, in part, of the Rio Grande do Norte educational history in a determined period, the 60 s years

O Curso Normal de 1º Ciclo em Assu/RN (1951-1971)

The aim of this research is the analysis of the history of the Normal Course in the 1st period in Assu, Rio Grande do Norte, since its foundation by the state law no. 621, de 06 December 1951 until its demise, with the implementation of the Course of the Magisterium, by Federal Law 5692 from August 11, 1971. The goal is to answer how it was constituted the operation and the educational practices of this institution, teacher trainers, throughout its existence. For this, we analyze the institution's documents in focus interviews, legislation, of the education, newspapers and books of the season, guiding itself by the studies of Chartier (1991), Elias (2001), Certeau (2001), Frago (1995), Magalhães (2005) and Julia (2001). When dealing with an educational institution, the central category of analysis is the school culture, in which supported the cutting of specific categories of study: the entrance into the Normal Course, the conferring of a degree, the "Normalista Week‖ in Assu and formative elements. The Normal Course from 1st cycle formed teachers in a basic level, differing themselves from schools of teacher education of 2nd Cycle. It was founded in Assu as Regional Training Course and called Ginásio Normal in 1961.In the temporal cut studied, 279 women and 07 men were graduated as Regents of Elementary School, demonstrating a school attended virtually by women. In the narrative, it is restored to the inclusion of female students in the Normal Course, focusing on the processes of registration and the admission exams, graduation events, imbued with discourses on the social role of the teacher and the Party Normalista Week, which valued the sense of belonging with of students to the profession. Through theater plays in the school, of practices forming behaviors and stages of female students in elementary school, training elements are reassembled, demonstrating the discourse of modern education intermingled with the Christian Catholic values of the culture for female education. The reconstruction of the historical identity of this institution sometimes close, sometimes unique, when confronted with other schools of teacher training brings a contribution to the setting of the history of schooling in the state of Rio Grande do Norte

Literatura de monteiro lobato no ensino de ciências

Advocating education as a humanizing task, the humanizing function of literature and the importance of scientific education, this paper proposes linking Science and Literature in Science Teaching using two specific books of Monteiro Lobato in the final series of elementary school level. Adopting the action research methodology, an interdisciplinary approach, we used the books A Reforma da Natureza and Serões de Dona Benta in two classes (8th and 9th) at Escola Estadual Professor José Mamede, located in the town of Tibau do Sul, Rio Grande do Norte. The readings were performed in Portuguese Language s course and the scientific content were discussed in Science´s classrooms. The book A Reforma da Natureza permitted to approach issues related to the environment, while the use of Serões de Dona Benta showed particularly its effectiveness in questioning the concepts of matter, mass, weight and some questions about the Nature of Science (NOS). In general, the analysis of results shows that the readings of these two books permitted interaction and dialogicity in the classroom, as well as indicates the potential of these books in contextualing and questioning the scientific content contained in it. We advise, however, the need for the science teacher be aware of the conceptual mistakes present in literary works, avoiding erroneous learning and reinforcement of alternative conceptions

Algoritmo SOM com estrutura hierárquica e dinâmica aplicado a compressão de imagens

ln this work the implementation of the SOM (Self Organizing Maps) algorithm or Kohonen neural network is presented in the form of hierarchical structures, applied to the compression of images. The main objective of this approach is to develop an Hierarchical SOM algorithm with static structure and another one with dynamic structure to generate codebooks (books of codes) in the process of the image Vector Quantization (VQ), reducing the time of processing and obtaining a good rate of compression of images with a minimum degradation of the quality in relation to the original image. Both self-organizing neural networks developed here, were denominated HSOM, for static case, and DHSOM, for the dynamic case. ln the first form, the hierarchical structure is previously defined and in the later this structure grows in an automatic way in agreement with heuristic rules that explore the data of the training group without use of external parameters. For the network, the heuristic mIes determine the dynamics of growth, the pruning of ramifications criteria, the flexibility and the size of children maps. The LBO (Linde-Buzo-Oray) algorithm or K-means, one ofthe more used algorithms to develop codebook for Vector Quantization, was used together with the algorithm of Kohonen in its basic form, that is, not hierarchical, as a reference to compare the performance of the algorithms here proposed. A performance analysis between the two hierarchical structures is also accomplished in this work. The efficiency of the proposed processing is verified by the reduction in the complexity computational compared to the traditional algorithms, as well as, through the quantitative analysis of the images reconstructed in function of the parameters: (PSNR) peak signal-to-noise ratio and (MSE) medium squared error

Perspectivas de inserção da energia solar fotovoltaica na geração de energia elétrica no Rio Grande do Norte

The generation of electricity in Brazil is predominantly renewable, with internal hydraulic generation being more than 70% of its energy matrix. The electricity rationing occurred in 2001 due to lack of rain, led the country to increase the participation of alternative energy sources. This need for new sources of energy makes the regional potential to be exploited, which configures the change of generation model from centralized generation to distributed generation. Among the alternative sources of energy, the solar energy is presented as very promising for Brazil, given that most of its territory is located near to the equator line, which implies days with greater number of hours of solar radiation. The state of Rio Grande do Norte (RN) has one of the highest levels of solar irradiation of the Brazilian territory, making it eligible to receive investments for the installation of photovoltaic solar plants. This thesis will present the state-of-the-art in solar photovoltaic power generation and will examine the potential for generation of solar photovoltaic power in Brazil and RN, based on solarimetrics measurements conducted by various institutions and also measurements performed in Natal, the state capital

Atribuição de significado ao conceito de proporcionalidade: contribuições da história da matemática

This study is the result of a work which approaches the Mathematics History how source of the meaning s attribution in the proportionality concept. We adopt the methodology of the source qualitative and we work with a group of teachers from instruction s public system of the fundamental and medium level from Pocinhos City Paraíba. For the data collection, we use the field notes, the questionnaire, a sequence of activities and the interview semistructured like instruments. The study had how objective to know the significates attributeds to proportionality concept through of the activity mediate from Mathematics History, besides to investigate if a approach of the nature enables modification according to this sense. The results obtaineds though the data analysis indicate that the activities bring contributions which refer to achieve objectives. On the other hand they also showed that we have a long trajectory to be trailed in the meaning of to turn the Mathematics History a subsidy effective in the teachers practice, in view of the formation absence in the knowledge area, besides the necessity of the approach adequated of the Mathematics History in the didatics books of Mathematic

O império do desentendimento humano: representações da realidade em textos de dalton trevisan

This work has the general proposal of studying the composition of the trevisanian fictional universe, the aesthetic expression engineered to formulate this universe, and last, the representations of reality that emanates from this aesthetic-narrative construction. It seemed to us, however, that it would be impossible to cover, even superficially, so vast and voluminous set of texts as the trevisanian. Therefore, so that we could accomplish this task, and still do it in a way that was, at the same time, plausible and thorough, it was necessary an objective cut within that library. Then we selected a book, representative of the whole trevisanian work, which served as the object of study: Cemitério de Elefantes, 1964, one of the first books of short stories by this author. Within this one, we focused even more our sight, then moving towards what we call a reality forked in paralytic world and world in violence . Supported by the theories and methodologies of Auerbach (2011), Candido (2002, 2006), Adorno (2003), Gennete (1995), Friedman (2002), and still moved by the spirit of Russian Formalism (1973), we built our criticism. Our approach was based then in three steps: first we are dedicated to comment the general context of the trevisanian work, supported strongly by reading two of the biggest critics of his literature, Miguel Sanches Neto and Berta Waldman, secondly, we turn us to comment on the detailed formal construction of language and narrative elements of the trevisanian prose; finally we raised our criticism to the level of reading representations of reality, and then we started to comment the construction of the trevisanian fictional universe, focusing in splitting this universe in paralytic world and world in violence

Sistematização de conteúdos da Educação Física para as séries iniciais

The school culture reveals an organization, over all in terms of the distribution of the contents throughout the different levels of education. However, the Physical Education does not have its contents systemized, that is, there are no clearly definite criteria that can assist the teacher in the curricular organization, as well as, are restricted the didactic books of reference for the area. So, the aim of this study was to try the identification of relevant contents for the teach-learning of the scholar Physical Education pertaining of 1(a) to 4(a) series, as well as, a suggestion to organize these contents in a systemize form, respecting a pedagogical sequence for the indicated series. Field research was carried out, in which was used the practical experience of two of the authors of this article, that are Physical Education teachers, throughout three years. The data were collected by descriptions and daily of field, of the positive experiences lived by the teachers.

Organização temática da doutrina jurídica: elementos metodológicos para uma proposta de extensão da classificação decimal de direito

Specificity and updating of the bibliographic classification systems can be considered a determinant factor to the quality of organization and representation of the legal documentation. In the specific case of Brazil, the Brazilian Law Decimal Classification, does not foresee specific subdivisions for Labor Law procedures. In this sense, it carries out a terminological work based on table of contents of doctrinal Labor Law books of the mentioned area, which are compared to the conceptual structure of the Brazilian Law Decimal Classification. As a result, it presents an extension proposal for Labor Procedures as well as a methodological background for further extensions and updates.

Influência do fotoperíodo no consumo alimentar, produção e composição do leite de ovelhas Bergamácia

O objetivo deste trabalho foi avaliar o efeito do fotoperíodo sobre o consumo alimentar, produção e composição do leite (gordura, proteína, lactose, sólidos totais) e número de células somáticas de sete ovelhas da raça Bergamácia, submetidas a um fotoperíodo considerado curto (12 horas luz:12 horas escuro), e oito ovelhas da mesma raça, a um fotoperíodo longo (18 horas luz:6 horas escuro), durante as últimas quatro semanas de gestação e três meses de lactação. Para comparação, foi utilizado o teste t para duas amostras independentes. O consumo alimentar avaliado, diariamente, para cada baia com duas ovelhas, não diferiu entre os tratamentos. No fotoperíodo curto, o consumo médio diário foi de 4,48 kg e, no fotoperíodo longo, de 4,40 kg. Não foi observada diferença significativa entre os fotoperíodos, para a produção de leite e teores de proteína, lactose e sólidos totais, quando considerados os 84 dias de lactação. No fotoperíodo curto, a porcentagem média de gordura foi 5,57%, índice superior ao obtido no fotoperíodo longo, de 5,21%. Na análise dos resultados, a cada semana, notou-se que na segunda e na quarta semanas de lactação, a produção de leite foi maior nas ovelhas do fotoperíodo longo. O número de células somáticas não diferiu entre os fotoperíodos e manteve-se baixo por toda a lactação. O maior número de horas de luz estimula a produção de leite no primeiro mês de lactação, principalmente na quarta semana, e as porcentagens de gordura e sólidos totais são menores nos períodos de maior produção de leite.

Students' preferred teaching techniques for biochemistry in biomedicine and medicine courses

The aim of this study was to investigate the students' preferred teaching techniques, such as traditional blackboard, power-point, or slide-projection, for biochemistry discipline in biomedicine and medicine courses from São Paulo State University, UNESP, Botucatu, São Paulo, Brazil. Preferences for specific topic and teaching techniques were determined from questionnaires on a Liquert scale from 1 to 5 (strongly disagree; disagree; neither agree, nor disagree; agree; strongly agree) distributed at the end of biochemistry discipline to 180 biomedical students (30 students/year) and 540 medical students (90 students/year), during the years 2000-2005. Despite of the different number of hours applied to the course topics for the two groups of students, the majority of undergraduates from biomedicine and medicine preferred metabolic topics. Although the perception of a medical student is expected to be different than that of a biomedical student, as the aims of the two programs are different, 92.4% of students from each course agreed or strongly agreed with the biochemistry topics, and 92.1% thought highly on this subject. The majority of students, a number of 139 undergraduates from biomedicine and 419 from medicine course, preferred traditional blackboard teaching than slide-projection, or power-point class. In conclusion, it is imperative that the health courses reflect on sophisticated technology and data presentation with high density of information in biochemistry discipline. The traditional classes with blackboard presentation were most favored by students from biomedicine and medicine courses. The use of students' preferred teaching techniques might turn biochemistry more easily understood for biomedical and medical students. © 2007 by The International Union of Biochemistry and Molecular Biology.
