O estudo da variabilidade da precipitação é importante para o planejamento das atividades econômicas, possibilitando o uso mais eficiente e racional dos recursos hídricos. Dessa forma, o objetivo desta pesquisa é caracterizar o estado do Rio Grande do Norte com relação à variabilidade temporal da precipitação, agrupá-lo em regiões homogêneas e comparar diferentes técnicas de agrupamento. Para o estudo da variabilidade pluvial foram utilizados os índices: Grau de Concentração de Precipitação (PCD), que representa o grau em que a precipitação é distribuída ao longo do ano; e o Período de Concentração de Precipitação (PCP), que reflete o período no qual a precipitação está mais concentrada. Para a realização dos agrupamentos foram escolhidas as variáveis: PCD, PCP, médias da precipitações anuais e médias das precipitações mensais. Posteriormente, foi aplicada a análise de agrupamento para obter grupos com características similares. Os resultados mostraram que as precipitações são melhor distribuídas na região leste do estado, neste caso, os meses mais chuvosos são de maio a agosto. Os municípios localizados nessa área possuem dois picos de chuvas, devido à atuação de dois sistemas: Perturbações Ondulatórias dos Alísios (POA s) e Zona de Convergência Intertropical (ZCIT). Nas regiões localizadas a oeste os meses que possuem maior concentração de chuvas são março e abril, neste caso temos apenas um pico de precipitação, devido a atuação da ZCIT. A identificação de áreas homogêneas favorece o planejamento adequado de acordo com as características de cada grupo formado e o RN pode foi dividido em 4 (quatro) regiões homogêneas. As técnicas de agrupamento utilizadas apresentaram resultados semelhantes, porém, sugere-se o uso de mais de uma técnica para que se possa analisar qual delas reflete melhor a realidade local. O estudo da variabilidade de precipitação, através dos índices estudados e do agrupamento realizado, são ferramentas adequadas ao planejamento ambiental e econômico

Brazilian high school teaching has passing through important changes. Based on current legislation and other official documents this research focus on the notion of contextualization, discussing the possibilities of a Physics teaching contextualized at a kitchen environment. Given the difficulties presented by students in establishing the relation between the contents discussed in classroom and their own daily lives, we propose the elaboration and application of a didactic unity. This started after the analyses of an initial questionnaire answered by the students. The didactic unity was elaborated based on an earlier proposal made by GREF (Physics Teaching Reelaboration Group) for a Thermal Physics course, and involved situations on students daily lives, in particular, those activities tried to relate formal contents discussed in classrooms to the kitchen environment. The didactic unity was applied to a public high school classroom at Limoeiro do Norte (CE). After evaluation of this experience it is possible to state that contextualization is a challenge that shall be faced, so that students may have a more critical look at physics, understanding that this subject is of relevance to all of us and is present in all world around us

A ação do DIP tem recebido particular atenção, sobretudo quando se trata de evidenciar o caráter repressor e controlador que o órgão de fato exerceu. Menor ênfase tem sido dada a sua ação como editor e financiador de obras favoráveis ao regime: no mais das vezes, não se vai além da citação de uma lista de títulos favoráveis ao regime, que comprovam o investimento na imagem do chefe. Pesquisa realizada em dois acervos norte-americanos permitiu manipular um rol significativo de obras publicadas no período, as quais apontam para uma trama complexa entre autores, editores e gráficas. Além disso, a presença desse material no exterior indica os esforços do regime para atingir uma audiência internacional.

Recent research has revealed that the majority of Biology teachers believe the practice of experimental activities as a didactical means would be the solution for the improvement of the Biology teaching-learning process. There are, however, studies which signal the lack of efficiency in such practice lessons as far as building scientific knowledge is concerned. It is also said that despite the enthusiasm on the teachers‟ part, such classes are rarely taught in high school. Several studies point pedagogical difficulties as well as nonexistence of a minimal infrastructure needed in laboratories as cause of low frequency in experimental activities. The poor teacher performance in terms of planning and development of classes; the large number of students per class; lack of financial stimulus for teachers are other reasons to be taken into account among others, in which can also be included difficulties of epistemological nature. That means an unfavorable eye of the teacher towards experimental activities. Our study aimed to clarify if such scenario is generalized in high schools throughout the state of Rio Grande do Norte Brazil. During our investigation a sample of twenty teaching institutions were used. They were divided in two groups: in the first group, five IFRN- Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte schools. Two of those in Natal, and the other three from the country side. The second group is represented by fifteen state schools belonging to the Natal metropolitan area. The objectives of the research were to label schools concerning laboratory facilities; to identify difficulties pointed by teachers when performing experiment classes, and to become familiar with the conceptions of the teachers in regarding biology experiment classes. To perform such task, a questionnaire was used as instrument of data collecting. It contained multiple choice, essay questions and a semi-structured interview with the assistance of a voice recorder. The data analysis and the in loco observation allowed the conclusion that the federal schools do present better facilities for the practice of experimental activities when compared to state schools. Another aspect pointed is the fact that teachers of federal schools have more time available for planning the experiments; they are also better paid and are given access a career development, which leads to better salaries. All those advantages however, do not show a significantly higher frequency regarding the development of experiments when compared to state school teachers. Both teachers of federal and state schools pointed infra-structure problems such as the availability of reactants, equipments and consumption supplies as main obstacle to the practice of experiments in biology classes. Such fact leads us to conclude that maybe there are other problems not covered by the questionnaire such as poor ability to plan and execute experimental activities. As far as conceptions about experimental activities, it was verified in the majority of the interviewees a inductive-empiric point of view of science possibly inherited during their academic formation and such point of view reflected on the way they plan and execute experiments with students

This dissertation proposes studying the issue of withdrawal undergraduate in physics at the Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN) and collaborate with suggestions for dealing with this problem. The first chapter begins with an overview of two significant problems in the Brazilian educational system: the high dropout rates in degrees in physics and the lack of teachers with specific training in this science. Then, we discuss the relevance of this research to the area of physics teaching, as well as justify its completion as part of a professional master's degree. After, we present a proper definition for the term withdrawal, which is based on the existing problem in the IFRN. And, in the same chapter, we explicitly the focus, the objectives and the methodological aspects of this work. The results obtained in our investigation are presented in next four chapters. In the second chapter of this dissertation, we present: a brief history of the creation of IFRN degree in physics, the functioning of this course and the foundation of classrooms 2004.2 and 2006.1. We also show a kind of map of the withdrawal of the groups investigated (the dropout rate was 84.4% in both groups) and an analysis of the relationship between the curricula of each of them and the number of dropouts. In the third chapter, we display a descriptive statistics of the students which dropout and found that the largest dropout occurred with students who are women, married, parents of one kid; workers, joined with a minimum age of 23 years and completed high school at least 6 years. Then in the fourth chapter, we reveal and discuss the students' reports on the causes of their dropout. From the data presented, we can say that the answer to the question "What was the main reason for your dropout?" Is mainly in personal injury claims: another option for upper-level course and lack of time to devote to the course. In the fifth chapter, we show the results related to teacher s opinions about the phenomenon in question. We detected three main causes for the abandonment, according to teachers: the lack of dedication, the lack of interest and lack of integration in the course. In the sixth and final chapter, we discuss the results and present our conclusion and the proposed report - the product of this dissertation, presented as Annex. This report contains mainly suggestions for curricular and institutional actions that can contribute to reducing the dropout degree in Physics in the IFRN. The main actions suggested are: implementation of the curriculum in disciplines, implementation of programs or actions to combat this poor content of basic training, implementation of specific programs or actions for the student worker, and dissemination of IFRN degree in physics in schools through seminars or workshops

To the observe the periods of electoral campaigns, we can realize sharply the abundance of political propaganda that announces the candidates, their campaign record, their proposed and everything that can carry them to the victory in the urns. The propaganda is today an essential tool in the votes dispute, in consequence of this, there is, in Brazil, the increasing participation of the Politics Parties in seminars of electoral marketing. They are varied strategies of the media used in the divulging of the candidacies, among them the slogan. Instigated by the explicit relation media/political, this work intends to investigate the ideologies (values) announced by the slogans of political propaganda that circulated in electoral periods. Thus, we base on the theory of the Circle of Bakhtin, who considers the statement as unit of the verbal communication, and that conceives the language as phenomenon dialogical, and, too, in the conceptions of alien words, social voices and dialogical relations formulated by the referred theory. We use, for better to comprehend, the slogan as strategy mediatic, of the classical study done by Olivier Reboul concerning the slogan; and, like starting point of a conception about ideology, studied John Thompson to comprehends the ideological phenomenon. Our corpus it constitutes of 14 political slogans announced in the campaigns for mayor of the cities in Natal and Mossoró, both located in Rio Grande do Norte s state, Brazil, in 1996, 2000 and 2004. For the analysis of these slogans, we consider the social-historical context in which were announced, being contemplated the linguistic and discursive aspect, according to the following methodological order: the identification of alien words (interdiscours); the social voices and the kinds dialogical relations established; and, finally, the ideology announced by the statement. This way, we can arrive to the conclusion that in the electoral context occurs a true ideologies war , in other words, in the political game of an electoral campaign, the slogans announces different values, which vary in several factors function, for example, the historicity, the subject that enunciates, the discursive positionings.

The diachronic studies marked the first decades of the 20th century in Brazilian linguistics, passing by an ostracism period after the 50s. Mainly from the 90s especially with the project, created in 1997, Para a história do português brasileiro (PHPB), which has systemized, in national ambit, the programme related to the area of diachrony the historical studies retake forces and have gradually increased since then. Our work is set in the new scene of Brazilian historical linguistics and it is associated to two research programmes: i) the constitution of a diachronic corpus; ii) the diachrony of text and discourse. As regards the first programme, we made effort to constitute a diachronic corpus of official letters about Rio Grande do Norte, we called cartas oficiais norte-rio-grandenses, written in 18th, 19th and 20th centuries. The chosen for bureaucrat letters occurred for they represent a textual category very productive in historical contexts, mostly 18th and 19th centuries, in which the command of writing was the least and also because they bring, almost always explicitly, the information of where, when, for whom and from whom, as remembers Fonseca (2003). The rules for constituting the corpus were based, although not strictly, on the orientation from PHPB. In respect to the second programme, we set up on the ideas of coserian base came from the studies on discourse traditions (TD) (Koch, 1997; Kabatek, 2006) amongst which that the texts are shaped so as to follow their own tradition (Coseriu, 2007), and we turned to Diplomatics (Belloto, 2002) in order to do the characterization of this corpus by the application of concepts from Diplomatics and TD as well as by the presentation of the structures that form those official letters: their textual genres, a kind of TD, with their macrostructures; and some of their formulaic expressions (microstructures), another sort of TD. This stage of characterizing will pay attention, as far as possible, to the dynamic between tradition and innovation that happen in the actualization of those textual structures along the centuries. This work intends to contribute with the researches connected to Historical Linguistics in Rio Grande do Norte, more specifically the ones related to the constitution of diachronic corpora and to TD; and with the study of official documents, textual category about which there are almost no studies (cf. Silveira, 2007)

This work has as study object the representations that teachers have about literacy, and schooling, as well as their memories and their reading and writing practices in the formation process of teachers in rural areas of the State of Rio Grande do Norte. We focused our discussion in literacy practices constructed on language workshops, assumed as necessary for the teacher formation, the existence of a pedagogical context that allows developing the appropriate teaching action. These workshops aimed at creating a space of constant reflection and action. The corpus is composed of letters written by teachers in formation workshops and interviews emphasizing questions of literacy, schooling, memories and reading and writing practices. These teachers make use of literacy practices related to the plots which they belong to. This research is informed mainly by studies that discuss the Literacy (Street, 1984, 1995; Barton, 1998; Freire, 1978, 1980, 1990, 1996), focusing its political character and of inclusion to the literate world, the Social Representations (Moscovici, 1978) and the studies on genre as a discoursive practice (Fairclough, 2001). Methodologically, this research is of critical ethnographic nature (Cameron, 1992). The letters are disclosed as identity practices - pictures of life histories of the teachers. The analyses of the interviews, in turn, show the literacy multifaceted character, evidencing innumerable views on the phenomenon

The objective of this paper is to analyze how the female figure was portrayed in discursive narratives in the bi-weekly newspaper O PORVIR , which circulated in Currais Novos, in the state of Rio Grande do Norte, Brazil, between May 2, 1926 and January 20, 1929. Our analysis was based on the semantics of the text, by applying one of the primary concepts used in Textual Analysis of Speeches, Discursive Representation (ADAM, 2011; RODRIGUES; PASSEGGI; SILVA NETO, 2010). Textual Analysis of Speeches has its roots in Textual Linguistics and consists of a theoretical and descriptive approach (ADAM, 2011). This research is characterized as documentary (SEVERINO, 2007) and its corpus includes a review of 39 editions of the aforementioned newspaper, of which we extracted 292 articles that dealt with the female figure and 396 statements for analysis. We used the following semantic categories: referencing (CASTILHO, 2010; NEVES, 2007; KOCH; MARCUSCHI, 1998; MARCUSCHI, 2008; KOCH, 2009); predication (NEVES, 2007; RODRIGUES; PASSEGGI; SILVA NETO, 2010); modification (ADAM, 2011); and spacial and temporal localization (RODRIGUES; PASSEGGI; SILVA NETO, 2010). Our analysis revealed that lady, mother, wife and homemaker were most represented, and always combined with questions about motherhood, marriage and devotion to the home. Such representation does not diverge from pre-colonial models in the early twentieth century, which served as a standard for the female figure

Considering the theoretical and methodological presuppositions of Variationist Sociolinguistics (cf. WEINREICH; LABOV; HERZOG, 2006; LABOV, [1972] 2008), in this dissertation, we describe and analyze the process of variation/change involving the personal pronouns tu and você, and its extension in the pronominal paradigm in Brazilian Portuguese (BP), in three sets of personal letters written by people from Rio Grande do Norte (RN) along the 20th century. The discursive universe of those letters is news from the cities in which the informers lived and the themes from their everyday life (trade, jobs, trips, family and politics). Part of the analyzed letters integrate the written by hand minimum corpus of the Projeto de História do Português Brasileiro no Rio Grande do Norte (PHPB-RN). We are based on previous studies about the pronominal system in BP Menon (1995), Faraco (1996), Lopes e Machado (2005), Rumeu (2008), Lopes (2009), Lopes, Rumeu e Marcotulio (2011), Lopes e Marcotulio (2011) e Martins e Moura (2012) , which register the form você replaces tu from the end of the first half of 20th century and attest the following situation: while (a) the imperative verbal forms, (b) the explicit subjects and (c) prepositional complement pronouns are favorable contexts for você, the (d) non imperative verbal forms (with null subject), (e) the non prepositional complement pronoun and (f) the possessive pronoun are contexts of resistance of tu. The results got in this dissertation confirm, partially, the statements defended by the previous studies regarding the favorable contexts for the implementation of você in BP: (i) there are, in the letters from the first two decades of 20th century (1916 to 1925), high frequency of the usage of the form você (98%); (ii) in the personal letters of RN especially in the love letters, in which there are higher recurrence of intimate subjects the discursive universe proved to be itself very relevant in the determination/conditions of the forms of tu; (iii) the unique feminine informer of our sample uses, almost categorically, the forms of tu in letters of the period from 1946 to 1972; (iv) the letters corresponding to the period from 1992 to 1994 present a significant usage of the forms associated to the innovating você, letting appear the change is already implemented in the system of BP and there are, in that set of letters, strong evidences that make us state the pronominal forms of non prepositional complement (accusative/ dative) related to tu are also implemented in a system with an almost categorical usage of você

In this dissertation, we analyze the constitution and functioning of the humorous discourse in discursive genre cartoon from the recognition and analysis of the techniques of humor used to get the desired effects of meaning. We used the theoretical and methodological assumptions of French Discourse Analysis henceforth (AD) for the research. Specifically on the techniques of humor, we rely on authors like Possenti (1998) and Propp (1992) to see how these procedures are present in the cartoons and make the discourse of humor. To achieve this goal, ten (10) cartoons were analyzed dealing with episodes relating to the management of the mayor Micarla de Souza in the city of Natal, RN. These cartoons were published in the newspaper Tribuna do Norte during the year 2012. The research falls within the field of study of Applied Linguistics and is qualitative, interpretive nature. In the first part, we did a rescue of the foundations of discourse analysis, discussing the concept of interdiscourse, then we carry on about the notion of gender discourse from the perspective of AD, and the genre itself cartoon as we work with the cartoon as a discourse genre, and finally, we deal with this humor discourse in cartoons. We then developed some analyzes to illustrate the postulate that all text is founded upon certain conditions of enunciation; that the relationship between the cartoons and interdiscourse is a constitutive relationship that brings out certain cartoons/ discourses and not others, and especially what humor techniques are used strategically by the cartoonist, whose discursive decisions cause certain effects of meaning. The results of this paper find that discursive relations are relations of subjects and meanings, that the discourse of cartoon is built from other sayings and discourses, and that certain textual and discursive procedures/techniques, as parody, irony, lowering the other, the ambiguity and displacement are mobilized in the text to generate the possible effect of the comic, thus building the humor discourse of the cartoons analyzed

The text, to be held in different linguistic spheres, in many aspects absorbs the changing processes through which language passes as a result of socio-historical changes. In this sense, this research proposes a study on gender sorted, motivated by the desire of understanding how the text incorporates traces of change and how to keep its constituents over time, in order to point out what are its characteristic traits. Our analysis is centered on the newspaper s section called classificados of Tribuna do Norte, state of Rio Grande do Norte, between the XX and XXI centuries. From the survey data a descriptive and analytical analysis was performed with a corpus of 250 listings, divided between the years 1951-2010. Based on a diachronic analysis, we also seek to investigate the macro-structural aspects of gender and microstructural compositional elements from the opportunities section that originated the Caderno de Classificados . For this reason, this approach has focused on particular Roman German Philology, especially in the works of Coseriu (1980) and Kabatek (2006). The analysis revealed that since its inception in Brazil, the classificados have fixed constituent elements, such as the use of "sell" and "rent" in the title or introduction, but also shows traces of change in the closure of the text, and especially with regard to the division of classificados by area of interest, that in the newspaper called Tribuna do Norte started in the Opportunities section

The focus of this qualiquantitative research is the phenomenon we are denominating Drama-of-Rio-Grande-do-Norte, which contemplates short verse texts from the oral tradition, sung and presented on stage by women in communities on the south coast of the northeastern Brazilian State, Rio Grande do Norte. This tradition harkens to the medieval romance of the Iberian Peninsula (CASCUDO, 2001; GURGEL, 1999; GALVÃO, 1993; MAGALHÃES, 1973; ROMERO,1977). The objective of this research is to: identify what characterizes the genre Drama of Rio Grande do Norte; situate this genre within a systemization of genres from the oral tradition in Rio Grande do Norte; investigate the interpersonal relationships of power and solidarity through the role of the women in the discourse, how they see themselves and others, pointing out which elements of the world they evaluate and to identify representations of the feminine in the discourse. The theory of Genre and Register of Martin and Rose (2008) and Generic Structure Potential of Hasan (1989, 1996), which has as a base the Systemic Functional Linguistics of Halliday and Matthiessen (2004), Eggins (1994) among others, offers a theoretical framework for the characterization of the genre through the identification of stages and phases configuring its typology the individual schematic structure and its topology its relation to other phenomena in the oral tradition. Other groupings were mapped of the ‗Macrogenre , from the model of Martin and Rose (2008) as a continuum on two axis: between the poles of how the genre circulates orally x in writing, and recited/individually x staged/collectively; as well as mapping the samples with relation to power using the same model, but with the poles of individual voice x collective voice on an axis between increased power and diminished power. Eleven texts described as Narratives and one Anecdote were selected for the analysis of Attitudes, and Negotiations of power. Through the quantification of semantic discursive resources in the discourse systems of Appraisal (MARTIN; WHITE, 2005) and of Negotiation (MARTIN; ROSE, 2007), as well as reflections about humor (EGGINS; SLADE, 1997) we identified the Attitudes and the Negotiations of interpersonal roles. The quantification is based on the theories of Corpus Linguistics (BERBER SARDINHA, 2010), using WordSmith Tools 5.0 (SCOTT, 2010). Our results show that the Drama-of-Rio-Grande-do-Norte is characterized as a Macrogenre in the Community of Oral Stories, in the Family of Street Theatre/Games, composed of five genre types: Narratives, Praise, Complaints, Anecdotes, and Exemplum. The Macrogenre is characterized by its being circulated orally, staged collectively and the texts analyzed configure in differing degrees of power between men and woman. In synthesis we observe that through humor, the Drama-of-Rio-Grande-do-Norte functions to offer a space for women to voice, comment, judge and orient about social conditions in their communities, such as alcoholism, domestic violence, inequalities before the law etc., as well as circulating positive appreciations of rural/coastal culture and judgments about the behavior of members of the speech community, the role of women being to establish and reinforce norms. We anticipate possible benefits of the addition of the genre analyzed in literacy projects in the schools of Rio Grande do Norte

La cultura del libro impreso impregna la vida cotidiana de los lectores durante más de cinco siglos, y de esto, hábitos y significados a cerca del libro como medio de comunicación tienen sus raíces en la comunidad lectora, en una especie de contrato de lectura (VERÓN, 2004). Por lo tanto, creemos que es posible conjeturar que la aparición del libro digital puede cambiar las viejas prácticas en relación con el libro impreso y por eso mismo deben ser investigadas con el fin de entender este tiempo de productos reconfigurados. Consciente de ello, el tema central de nuestra investigación se basa en la comprensión de cómo los lectores de libros digitales realizan sus prácticas. Nuestro objetivo general es investigar las prácticas socioculturales de los lectores de libros digitales, con el fin de mostrar las continuidades y discontinuidades en el uso del libro en su formato impreso y digital. Con este fin, se busca 1) proponer una caracterización de la cultura del libro impreso, que es el apoyo a una asignación posible de las marcas de una cultura del libro digital, y 2) explorar los lugares de producción y oferta de los libros digitales, especialmente en Brasil, fin de delimitar en su primera configuración. Apoyamos, como propuesta metodológica, la sistematización de dimensiones culturales del libro impreso llamadas: ritualidad, simbología, materialidad y forma, lo que ayudará el enfoque del empírico. Nuestra propuesta se basa, en varios puntos, en los investigadores de la historia del libro, insertada en el campo de la Historia Cultural (BURKE, 2008; CHARTIER, 1992, 1994, 2006; DARNTON, 1990, 2006, 2010). Adoptamos como técnica de investigación el análisis de voces, registradas a través de entrevistas en profundidad, de lectores de libros en formato digital. Antes de eso, creemos apropiado emprender un estudio exploratorio basado en la aplicación de un cuestionario online. Nuestra delimitación incluye lectores de libros digitales del curso de Comunicación Social de la Universidad Federal de Rio Grande do Norte. Entre las conclusiones de esta disertación, es posible señalar que el grupo de lectores investigados está sólidamente ligado a las experiencias con los libros impresos y esto afecta en gran medida las prácticas de los libros digitales
