O Gênero requerimento na perspectiva sociorretórica: análise da produção de graduandos no ambiente acadêmico-administrativo da UFRN

In administrative settings of public institutions, many activities are conducted through writing practices. Concerning this, writing is always connected to an activity we intend to perform. Among those practices, the genre request consists of an instrument through which the requirer addresses to an institution in order to request something under the support of legislation. Considering our work experience in a public institution of higher education, we elected - as object of our research - the genre request produced by undergraduates within the administrative domain of the Federal University of Rio Grande do Norte (UFRN) due to its importance in this context. For this, the theoretical framework adopted refers to the socio-rethorical conception of genre studies, which understands the genre as forms as rhetorically typified action (MILLER, 2009a; SWALES, 1990; BAZERMAN, 2009). Regarding methodology, it is a research associated to a qualitative approach (BODGAN; BIKLEN, 1994; CHIZZOTTI, 2010) whose discussion inserts into the field of Applied Linguistics. The data were generated from samples of requests and their users replies in questionnaires, interviews and verbal protocols of writing. The data analysis is based on the ethnographic methods of genre analysis postulated by Devitt, Reiff and Bawarshi (apud JOHNS et al., 2006). These analyses indicated that the requests are not always fully accomplished due to a lack of comprehension about the genre and its rhetorical situation on the part of the producers. It must probably happen - among other reasons - because these students may not have understood that several factors, such as: context, audience and purpose, affect the text production. We believe that one possibility to make the practice of this genre more efficient is to develop a more simple and practical way of elaborating requests, taking the needs imposed by the rhetorical situation as a basis

Samba e negritude: práticas discursivas identitárias negras em sambas de enredo de temática africana

The study object of this thesis is the process of affirmation, (re)construction and (re)signification of the black identities in the discourses which cross the samba-enredo of African theme of the samba schools belonging to the elite group from the carioca carnival, in the period from 1960 and 2007. The main question which guides this research is the following: How does this discursive process occur and which are the possible effects resulting from it? This research aims to understand, through interpretation gestures of such discourses and from those which undergo the interview statements and the answers given to the questionnaires applied to spectators and parade exhibiters of these samba schools, in what way the negritude conception and the citizenship practice of the black Brazilian people, especially those from Rio de Janeiro, can be affected by the meaning production circulating in the discursive practices of these sambas. The research was theoretically related to the Applied Linguistics, however it articulates theories originated from Cultural Studies and Ethnic-racial Studies as well as it presents some theoretical and methodological fundamentals from the Discourse Analysis of French line. As concerns the methodology, it is of interpretative, qualitative basis with procedures of discursive character. The interview analysis did not reveal, as consequence of the discourses circulating in the sambas, a direct involvement of the black people who were interviewed in struggle for their citizenship practice, but it pointed out sliding of meaning in regard to the negritude emergence

Mundos de letramento e agência na construção da identidade de seminaristas católicos

Atualmente, os conceitos de mundos de letramentos e agência social nos permitem observar o desenvolvimento de competências relacionadas às práticas sociais e às ações transformadoras que influenciam, de forma decisiva, a vida de jovens seminaristas e a vida das comunidades das quais fazem parte. Com este trabalho objetivamos contextualizar social e culturalmente os letramentos na esfera do lar e a influência da família na formação do seminarista bem como evidenciar o papel do grupo de jovens na formação pessoal e o fortalecimento do sentimento de autoestima produzido pela relação de confiança e pela delegação de responsabilidades. Procuramos, por fim, descrever os principais pilares formadores do Seminário, como agência de letramento, e sua importância na formação identitária do seminarista. Trata-se de pesquisa qualitativa de cunho etnográfico cuja metodologia baseia-se em análise de narrativas semiestruturadas e questionários sócio avaliativos. Os fundamentos teóricos que sustentam nossa pesquisa estão ancorados nos estudos de letramento (BARTON, HAMILTON, IVANI, 2000; STREET, 2003; OLIVEIRA, 2010), na Análise do Discurso (FAIRCLOUGH, 2001), no Realismo Crítico (ARCHER, 2000; AHEARN, 2001), na Sociologia (GIDDENS, 2003, 2005); (SZTOMPKA, 2005), no Interacionismo Simbólico (BERGER, P. L., LUCKMANN, 2009). A análise dos dados nos permitiu: 1) (re)afirmar o papel da instituição família como a principal guardiã do conjunto de ideias e valores, os quais fortalecem as representações sociais associadas a essa instituição, sendo responsáveis pela formação identitária de nossos colaboradores; 2) reconhecer o importante papel social desempenhado por instituições sociais informais que, com o objetivo de promover ações evangelizadoras e solidárias, proporcionam aos seus catequizados o desenvolvimento de múltiplas competências direcionadas à agência pessoal e social, dentre as quais destacamos as Pastorais como fortes aliadas nesse processo formador de identidades sociais positivas, porque os indivíduos que delas participam adquirem competências agentivas que são responsáveis por transformações de ordem pessoal e social; 3) descrever os processos formadores que permitem a manutenção da tradição dentro de uma instituição religiosa. Nossos achados apontam para a necessidade de compreendermos a sociedade como constituída e constituinte de muitos e diversos mundos de letramento, os quais estão a serviço de todo aquele que consegue se perceber como ser atuante no mundo

A produção do gênero monografia em discursos de professores e alunos do curso de letras

A current worry in the teaching process at the university these days is text production process and genres produced there, especially those kind of writing that is concerned to course conclusion such as monograph, dissertation and thesis. From this perspective and considering our aims at understanding discursive process involved in the production of monograph genre at the university we want to analyze teachers and students discourses about the productive process of monograph in Letras Course, considering the guide, writing and specific aspects of that genre. To get the aims, we took as background theory the studies by Bakhtin linked to Utterance Linguistics with foundation concepts in Discourse Text Analysis by Adam (2010), and finally the studies developed about text production at college. This way, this work is based on a qualitative research and in data ethnographic procedures, they are: the observation in locus, as well as the application of questionnaires with opened questions to ten students and six teachers from Letras Course. The discourse analysis from the subjects reveal us that: i) the monograph production and the guidance are form of act by language, that need take into account in its development: students free chose as a principle in writing monograph, as well as a wide involvement between the teacher and the student in a sense to turn the writing better, among other aspects; (ii) there is a need to articulate monograph project and the text produced, considering that the guide process comes from a project written before; (iii) there are a number of role to discourses by teachers and students to the function of student and guide teacher, in a way that both can see the same assumptions in teachers and students discourses; (iv) teacher s and students discourses show that they assume the utterance responsibilities by the content of utterances proposed, they also show the voice from methodology guidebooks to monograph texts. So, we conclude that this research has some contributions to teach writing production at the university, especially to monograph in the ending of the courses. It can also be helpful in developing research in this area, mainly at the question about guide final works at college

Sono e síndrome da fragilidade em idosos residentes em instituições de longa permanência

Introduction: The aging process causes quantitative and qualitative changes in sleeping. Such changes affects more than half of the adults above 65 years old, that live in the community and 70% of the institutionalized, a great negative impact in their quality of life. One of the pathological displays of aging, that share some characteristics with sleeping disorders and predict similar results, is the Frailty Syndrome, that characterize the most weakened and vulnerable elderly. The way sleeping disorders play a role in the frailty pathogeneses remains uncertain. Objective: Evaluate the relation between the sleeping and the frailty syndrome on institutionalized elderly. Methodology: A transversal study was performed with 69 elderly in institutions in the city of João Pessoa PB. Were used the Pittsburgh Sleeping Quality Index and actigraphy to subjective and objective variables, respectively, and questionnaires and specific tests to frailty phenotype variant (Fried Frailty Criteria). In the statistic analysis were used the Pearson correlation test, Chi Square and One-way ANOVA test, with Tukey-Krammer posttest. Subsequently, a Simple Linear Regression model was built. On every statistical analysis were considered a confidence interval of 95% and a p < 0,05. Results: The sample was characterized by the prevalence of the frail (49,3%), women (62,3%), single (50,7%) and 77,52 (±7,82).The frail elderly obtained the worst sleeping quality 10,37 (±4,31) (f = 4,15, p = 0,02), when compared with the non-frail. The sleep latency influenced more the frailty (R2 = 0,13, β standard = 1,76, β = 0,41, p = 0,001). Weren t found differences between the standard resting-activity variable and the frailty phenotype categories. Conclusion: Sleeping alterations, including bad sleeping quality, prolonged sleep latency, low sleep efficiency and day drowsiness, influenced the frailty in institutionalized elderly

Qualidade de Vida, Saúde Geral e Ansiedade em pacientes com diferentes tipos e níveis de disfunção temporomandibular

Some studies reported in the literature that emotional factors and quality of life may be involved both in aetiology, as in the progression of Temporomandibular disorders (TMD). Proposition: The purpose of this study is to observe a possible association between different forms of anxiety, quality of life and general health of patients diagnosed as carriers of various types and levels of Temporomandibular Dysfunction. Methodology: The sample consisted of 60 patients diagnosed as carriers of TMJD origin of muscle, joint, or both, with different levels of severity (mild TMD, moderate and severe). The patients were diagnosed with TMD-RDC (Research Diagnostic Criteria) to assess the type of dysfunction (muscle or joint) and by the Protocol of Fonseca to verify the degree of dysfunction (mild, moderate or severe). To evaluate the psychosocial aspects were used three self-applied, with the purpose of obtaining information about the general health (General Health Questionnaire - GHQ), the type of anxiety (Trait Anxiety Inventory-State - STAI) and quality of life (World Health Organization Quality Of Life Short WHOQOL-brief). Results: There was a correlation between all indicators studied in several forms of TMD with varying degrees of commitment. Quality of life appeared linked to the type and the level of TMD: Muscular and Articular TMD (p = 0,037), Disk Displacement With Reduction (p = 0.01) and Mild TMD (p = 0.042). The General Health showed association with the level of TMD, with the exception of the stress factor (p = 0.78). For the analysis of the types and levels to Severe Muscular TMD had a statistically significant indicator of the quality of life (p = 0049). The anxiety only showed association with the level of TMD (p = 0,047 for anxiety-trait). Conclusion: Besides the limitations of the study, it was concluded that anxiety, quality of life and general health are important psychosocial indicators, which are linked to several forms of TMD in different levels of severity

Desenvolvimento de uma metodologia para caracterização de amostras de sedimento: Rio Jundiaí RN

The study of sediment in water bodies presents great environmental importance, because of its ability to adsorb the pollutants, they may facilitate the understanding of the history of the current quality of the water system. Depending on how it is done the collection, analysis can show both a recent contamination as old. The detailed characterization of the sediment may reveal details that can understand how each type of pollutant interacts with the material given its composition. In this work it has developed a systematic methodology to characterize samples of sediment, with the aim to understand how a series of metal is distributed in different size fractions of the sediment. This study was conducted in five samples of sediment (P1, P2, P3a, P3B and P3c) collected in Jundiaí river, one of the most important tributaries of the river Potengi in the region of Macaíba, RN. The characterization was made with the samples previously sieved into meshes with different granulometries (+8#, -8+16#, -16+65# - 65+100#,-100+200#,-200+250# and -250#), using the following techniques: Analysis of specific surface area by BET method, determining the levels of organic matter (OM%) and humidity through the gravimetry and Analysis Thermogravimetric (TG), Infrared Spectroscopy in a Fourier transform (FTIR ), Analysis of X ray diffraction (XRD), analysis of heavy metals by optical emission spectrometry with the Argon Plasma (ICP-OES). The analyzed elements were Al, Cd, Cr, Cu, Fe, Mn, Ni, Zn and P. In addition to the techniques of characterization above, was also made the rebuilding of the samples P1, P2 and P3B in relation to the levels of organic matter and concentration of heavy metals. Then, the results of the recomposed samples were compared with those obtained in crude samples, showing great consistency. The gravimetry, used in determining the levels of organic matter, was not considered an appropriate method because the clay minerals present in the sediment samples analyzed fall apart in the same range of temperature (550-600 0C) used in roasting (600 0C). The results also showed the trend of organic matter and heavy metals to focus on the thin fractions, although the largest concentrations of metals are in intermediate fractions

Considerações sobre metodologia interativa aplicada à disciplinas de química orgânica de alguns cursos da UFRN

The aiming of this work is linked to chemical education, focusing organic chemistry classes of Chemical Engineering, Pharmacy and Zootechny graduate courses of the Federal University of Rio Grande do Norte. For that, teaching-learning process related to basic chemical subjects which support the understanding of organic chemistry concepts was evaluated in a research period of two years. The education proposal linked to the theoretical content of the cited classes, pointed out the process of knowledge construction, in which educational commitment as well as dedication in the teaching-learning process was also valued. In that approach several didactic tools were applied, among them scientific articles were used as supplementary studies of the basic organic chemistry concepts and related. The acceptability of students, as well as their motivation, performance and learning process was justified by the data collection of the applied teaching methodology. The acceptability and commitment of the students facing this teaching interactive approach, which transversely contributed to the intellectual maturity growth of the students, as well their professional development, were evidenced by satisfactory obtained results that will be herein discussed

Validação de metodologia para análise de aminas bioativas em camarão utilizando cromatografia de íons

In this study, we worked with the validation of a methodology for analysis of bioactive amines in shrimp, considering it to be one of the main products of the northriograndense trade balance, maintaining the state of Rio Grande do Norte topped the list of Brazilian exports of this product the last decade. The sector of the Brazilian shrimp works exclusively with gray shrimp Litopenaeus Vannamei since the late 1990s. This study used liquid chromatography with conductimetric detector, using as the mobile phase methylsulfonic 3 mM acid (MSA) with gradient and phase C18 column with reverse the development of methodology for the analysis of bioactive amines in shrimp. In the sample preparation was used as 5% trichloroacetic acid (TCA) extraction solution. Validation analysis of biotativas amines (putrescine - PUT, histamine - HIST, agmatine - AGM, spermidine - EPD and spermine - EPN) in shrimp, the linear working range was 0.1 to 2.0 mg L-1 to was sensitive, homoscedastic, in effect, selective, accurate and precise array. Thus, considered feasible for these determinations bioactive amines in this array. Determined the concentration of these amines in fresh shrimps (AGM = 0.61 ± 0.05 mg kg- 1 EPD = 2.57 ± 0.14 mg kg-1 and EPN = 1.79 ± 0.11 mg kg-1), and freezing weather predetermined in cooked shrimp (AGM = 6.28 ± 0.18 mg kg-1, EPD = 12.72 ± 0.02 mg kg- 1 and EPN = 22.30 ± 0.60 mg kg-1), the shrimp with twenty-four hour stay at room temperature (PUT = 879.52 ± 28.12 mg kg-1, AGM = 848.13 ± 19.40 mg kg-1, ESPD = 13.59 ± 0.97 mg kg-1 and ESPN = 18.47 + 1.57 mg kg-1). In shrimp subjected to freezing for a week, two weeks, three weeks and four weeks, the results showed that there is an increase in the content of agmatine (7.31 ± 0.21 mg kg-1) while in spermine ( 1.22 ± 0.14 mg kg-1) and spermidine (below limit of quantification) there was a decrease in the freeze time, while there is a decrease in the level of spermidine not reaching detectad. The putrescine was only found in shrimp that remained for 24 hours at room temperature and histamine was not found in any of the samples

Desenvolvimento de metodologia capaz de detectar e quantificar misturas de corantes em sucos artificiais em pó

Foi desenvolvido um método para detectar e quantificar misturas de corantes em sucos artificiais em pó fabricados no Brasil, de diferentes marcas e sabores. Foram estudados 6 corantes artificiais: amarelo tartrazina, amarelo crepúsculo, vermelho ponceau 4R, vermelho bordeaux S, vermelho 40 e azul brilhante presentes de forma unitária ou em misturas nos sucos com sabores laranja, tangerina, maracujá, abacaxi, limão e uva. A identificação dos corantes nas amostras foi feita através da comparação com os espectros dos padrões, utilizando-se a análise por infravermelho médio e pelos respectivos valores de absorção máxima nos comprimentos de onda relativos aos padrões e valores de referência na literatura. Também foram estudados os perfis de decomposição térmica por termogravimetria, termogravimetria derivada e calorimetria diferencial exploratória dos corantes e dos sucos em pó, sendo determinados os teores de umidade, de matéria orgânica e de cinzas. O teor de umidade encontrado não ultrapassou 4% para todas as amostras de suco analisadas. Com relação ao teor de matéria orgânica obteve-se para 57% dos sucos analisados um teor médio de 51,3% e para 43% das outras amostras obteve-se uma média de 67,2 %. Os resultados obtidos para o teor de cinzas indicaram que 29% das amostras apresentaram um teor de 26,7% para esse parâmetro enquanto 71% das amostras apresentaram um teor de cinzas de 46,4%. Os resultados obtidos por análise térmica mostraram-se adequados considerando-se que para obter os resultados pelo método tradicional há um investimento maior de tempo, de pessoal envolvido e de material, além da proteção ao meio ambiente. Para a análise por espectroscopia de absorção molecular foi proposta uma equação simplificada para a determinação de cada corante na mistura utilizando-se a lei de Beer. Para validação, empregou-se a espectroscopia de absorção molecular no visível, onde foi investigada a influência dos interferentes (TiO2 e açúcar) presentes nas amostras de sucos, os testes de fotodegradação e a avaliação do efeito do pH. Para quantificação tomou-se como referência 512 amostras sintéticas contendo um e dois corantes (1,5625 a 25,000 mg L-1) para obtenção das curvas analíticas que foram aplicadas à análise dos sucos em pó. Os resultados indicaram que o teor máximo do amarelo crepúsculo foi encontrado nos sucos com os sabores laranja, tangerina e manga que correspondeu a 25,6% da ingestão diária aceitável (para ser ultrapassada corresponderia a ingestão de 4 copos). O teor máximo encontrado para o amarelo tartrazina nos sucos foi para o sabor maracujá que correspondeu a 8,5% da ingestão diária aceitável, (para ser alcançado corresponderia a ingestão de 12 copos). O método proposto foi testado e validado com sucesso para amostras de sucos em pó sendo de simples execução e de rapidez na obtenção dos resultados

Adequação da metodologia para o teste de germinação de sementes de pitaia vermelha

Hylocereus undatus (Haw.), popularmente conhecida como pitaia vermelha é uma cactácea para a qual se tem registrado um aumento de consumo nos últimos anos e, por ser ainda pouco explorada, vários aspectos referentes à sua propagação ainda são desconhecidos. Até o momento, não existem critérios para a execução de testes de germinação para sementes dessa espécie, publicados nas Regras para Análise de Sementes. Nesse sentido, objetivou-se com este trabalho adequar a metodologia quanto ao substrato, temperatura e tempo de contagem inicial e final para o teste de germinação. Foram testados quatro substratos (rolo de papel, areia, vermiculita e solo) e quatro temperaturas (20, 25, 30 e 20-30°C). O efeito dos substratos no desempenho germinativo das sementes foi avaliado pelo teste de germinação e de primeira contagem instalado com quatro subamostras de 50 sementes. Foram feitas contagens diárias do número de plântulas emergidas até atingirem a estabilidade e, no final do experimento, foram avaliados a porcentagem de germinação das sementes, considerando as plântulas normais, anormais e sementes mortas. Concluiu-se que o teste de germinação de sementes de pitaia vermelha deve ser realizado à temperatura constante de 25°C em rolo de papel, com contagens inicial e final aos cinco e dez dias após a semeadura, respectivamente.

Adequação da metodologia do teste de envelhecimento acelerado em sementes de rúcula

The use of high vigor seed constitutes basic and fundamental. Given the increasing development os the seeds industry and the improvement of vigor tests used to differentiate subtle variations in the quality of seeds of vegetable crops, is needed. The objective was to study variations in conducting the accelerated aging test, to verify their sensitivity for identifying different vigor levels of arugula seed. Were used the cultivars Cultivada and Gigante, using five lots of seeds for each. The seeds were subjected to the determination of water content, germination, first germination, emergence of seedlings and variations in the accelerated aging test, without salt solution ( traditional procedure) and with salt solution in 48, 72 and 96 hours; at 38 degrees C, 41 degrees C and 45 degrees C. The accelerated aging test in traditional procedure is not efficient to evaluation the vigor of arugula seeds. The accelerated aging test with saline solution using the combination 41 degrees C for 72 hours, was sensitive to evaluated of the physiological potential of arugula seeds.
