A relação gramatical objeto direto : implicações para o ensino de língua materna

This paper attempts to investigate the discourse manifestations of the grammatical relation direct object with respect to the syntactic, semantic and pragmatic properties that underlie this element. The research adopts theoretical orientation of the functionalism from North American and Brazilian schools inspired in Givón (1995, 2001), Hopper and Thompson (1980), Chafe (1979), Furtado da Cunha, Oliveira, Martelotta (2003) inter alia. From functionalism, the research uses principles of iconicity, markedness and informativity and it analize categories of transitivity, grounding and animacy. This research is anchored in prototype model (TAYLOR 1995); construction grammar model (GOLDBERG 1996, 2002). Both theoretical orientations share the view that language is a malleable living organism subject to socio-cultural context. Grammar is then the result of created, maintained, and systematized linguistic patterns developed from and used for language use. According to a functional linguistics and cognitivist linguistics verbs are stored in the speakers lexicon in syntactic-semantic frames which are more frequent. These frames carry information concerning obligatory and optional arguments and the semantic roles these arguments take in the clause. The analysis focuses on the semantic type of the verbs and its relationship with the argument encoded as a direct object observing the aspectual nature of verbs. Direct objects are classified according to their morphology (lexical or pronominal noun phrase), semantic role, informational content and animacy. This study discusses pedagogical implications with relation to how the grammatical concepts touched on this paper are treated in school textbooks. The empirical data come from Corpus Discurso & Gramática: a língua falada e escrita na cidade do Natal (FURTADO DA CUNHA, 1998). This corpus is composed of texts that contain spoken and written modalities. These modalities are in turn organized according to different types: personal narratives, retold narrative, description of preferred place, procedural place, procedural description and report on argumentation. The sample data totals 40 texts produced by four language consultants of the last graduation date. The paper shows that the same syntactic structures (formed through Subject-Verb-Object) correspond to different semantic-pragmatic structures in relation to specific communicative purposes even verb is an event, process or state. The argument structure are not aleatory but are related to experience; that is the way humans conceptualize the world and talk about it

Vozes sociais em diálogo: uma análise bakhtiniana dos diários de leituras produzidos por alunos do ensino médio

The work aims to analyze high school students utterances, in reading diary discursive genre, starting from the language concept proposed by the Bakhtin Circle. The genre in question has peculiar characteristics which justify its choice for this work, especially with regard to subjectivity marks, that reveal, through the ideological clash, positions on various issues. From the utterances selected for the corpus, categories were created, during the research, according to the guidelines of Guba and Lincoln (2006), Mazzotti and Gewandsznajder (1998) and Amorim (2002), for whom the research in human sciences cannot be based on pre-established categories. We consider diary as a discursive genre (BAKHTIN, 2010a), which carries the characteristics of composition, style and content. Other concepts of the Circle, concerning to utterance, dialogical relations, social voices, responsiveness and exotopy also formed the basis for the study. Moreover, during the analysis of the utterances that compose the corpus of research, we used the concepts of discursive polemics (BAKHTIN, 2010b) and Framework (2010a). At the end of the research, we realized that the assessment situation of students, the fact that they are in an institution whose policy follows national documents, based on diversity and plurality, and live together in a classroom space where there are differences of social class, age, and finally, different realities, were not sufficient factors for this diversity be well accepted in their positions. Thus, their utterances bring voices that demonstrated a difficulty in accepting others that are different from themselves. In view of this, we conclude that teachers need to be prepared to handle these discourses, creating strategies for mediating these dissonant voices, with which must make contact every day at school

Um estudo da abundância de lítio, rotação, atividade cromosférica e magnetismo das estrelas análogas e gêmeas solares

The study physical process that control the stellar evolution is strength influenced by several stellar parameters, like as rotational velocity, convective envelope mass deepening, and magnetic field intensity. In this study we analyzed the interconnection of some stellar parameters, as Lithium abundance A(Li), chromospheric activity and magnetic field intensity as well as the variation of these parameters as a function of age, rotational velocity, and the convective envelope mass deepening for a selected sample of solar analogs and twins stars. In particular, we analyzed the convective envelope mass deepening and the dispersion of lithium abundance for these stars. We also studied the evolution of rotation in subgiants stars, because its belong to the following evolutionary stage of solar analogs, and twins stars. For this analyze, we compute evolutionary models with the TGEC code to derive the evolutionary stage, as well as the convective envelope mass deepening, and derive more precisely the stellar mass, and age for this 118 stars. Our Investigation shows a considerable dispersion of lithium abundance for the solar analogs stars. We also realize that this dispersion is not by the convective zone deep, in this way we observed which the scattering of A(Li) can not be explained by classical theories of mixing in the convective zone. In conclusion we have that are necessary extra-mixing process to explain this decrease of Lithium abundance in solar analogs and twins stars. We analyzed the subgiant stars because this are the subsequent evolutionary stage after the solar analogs and twins stars. For this analysis, we compute the rotational period for 30 subgiants stars observed by Co- RoT satellite. For this task we apply two different methods: Lomb-Scargle algorithm, and the Plavchan Periodogram. We apply the TGEC code we compute models with internal distribution of angular momentum to confront the predict results with the models, and the observational results. With this analyze, we showed which solid body rotation models are incompatible with the physical interpretation of observational results. As a result of our study we still concluded that the magnetic field, convective envelope mass deepening, and internal redistribution of angular momentum are essential to explain the evolution of low-mass stars, and its observational characteristics. Based on population synthesis simulation, we concluded that the solar neighborhood presents a considerable quantity of solar twins when compared with the discovered set nowadays. Altogether we foresee the existence around 400 solar analogs in the solar neighborhood (distance of 100 pc). We also study the angular momentum of solar analogs and twins, in this study we concluded that added angular momentum from a Jupiter type planet, putted in the Jupiter position, is not enough to explain the angular momentum predicted by Kraft law (Kraft 1970)

Associação entre diferentes marcadores antropométricos com variáveis espirométricas e de força muscular respiratória em obesos mórbidos

A obesidade é uma epidemia global em alarmante ascensão. Caracterizada pelo excesso de gordura corporal subcutânea, de caráter multifatorial, está relacionada ao surgimento de diversas co-morbidades, entre elas, várias alterações respiratórias, estas se tornam mais intensas quanto maior o grau de obesidade. Não há consenso na relação entre os marcadores de adiposidade geral ou específicos e suas repercussões sobre a função ventilatória, especialmente em relação à sobrecarga muscular respiratória. Objetivo: Analisar a relação entre marcadores antropométricos e variáveis espirométricas e de força muscular respiratória em indivíduos com obesidade mórbida. Métodos: Estudo transversal entre setembro de 2007 e outubro de 2012. Participaram da pesquisa 163 obesos mórbidos (37.1±9.8 anos e IMC=49.0±5.88 Kg/m2) sem alterações espirométricas. Foram observadas as associações entre Índice de Massa Corporal-IMC, adiposidade localizada (Circunferências de Pescoço-CP, Cintura-CC e Quadril-CQ), percentual de gordura corporal através do Índice de Adiposidade Corporal-IAC, volumes e capacidades pulmonares (CVF, VEF1 e VRE) e pressões respiratória estática (PIM e PEM) e dinâmica (VVM). Resultados: O VRE foi o volume mais afetado pela obesidade (apenas 41%predito) e mostrou associação negativa nas relações com todos os marcadores de adiposidade (IMC: r=-0.52; IAC: r=-0.21; CC: r=-0.44; CP: r=-0.25 e CQ: r=-0.28). Há relação inversa entre o percentual de gordura corporal (IAC) com a CVF (r=-0.59), o VEF1(r=-0.56) e o VVM (r=-0.43). As pressões respiratórias são justificadas principalmente pela adiposidade ao redor do pescoço e o IAC. Nossos dados de força muscular respiratória foram melhores associados aos valores de referências sugeridos pelas equações de Harik-Klan et al (1998) para PIM (R²=0.72) e com a equação proposta por Neder et al (1999) para PEM (R²=0.52). Em um modelo de regressão linear, as variáveis de adiposidade não justificam a VVM, já o VEF1 explica 62% da variância da VVM em obesos mórbidos. Conclusão: O percentual da adiposidade corporal e a circunferência do pescoço estão associados com a força muscular e capacidade de gerar fluxo respiratório de obesos mórbidos. Sugerimos a equação elaborada por Harik-Klan et al (1998) para obtenção de valores preditos de PIM e a equação proposta por Neder et al (1999) para valores de normalidade da PEM em sujeitos com obesidade mórbida. Foi possível fornecer uma equação de referência específica para VVM em obesos mórbidos

Cargos comissionados da administração pública direta do Rio Grande do Norte: análise comparativa entre o perfil profissional dos cargos comissionados com vínculo funcional e sem vínculo funcional

The professional profile of public administrators in Brazil is changing very rapidly in recent years, seeking to meet the principle of efficiency by public agencies at all levels. The admission of the permanent government employee under the Public Administration is by competition, however, commissioned positions are free appointment of managers, which allows effective participation of external experts according to their respective standards and norms. In this context, this dissertation seeks to understand the main characteristics of the profile of the occupants of commissioned positions in Direct Public Administration of the State of Rio Grande do Norte, noting the differences between those with functional link with the have nots. For this study, by data collection and content analysis, a mapping of the administrative structure of the Government of the State of Rio Grande do Norte was done, i.e., the organization of the Executive Branch, which is regulated by the Complementary Law no. 163/1999 and its amendments, which consists of 53 (fifty three) entities, these 29 (twenty nine) are agencies of the direct administration and the remaining 24 (twenty four) comprises the indirect administration. With the collected data, analysis on the number of commissioned positions of each organ of the State of Rio Grande do Norte and information on education, age, length of service, gender and functional link with the direct administration was carried out. Data were available from SEARH in June/2013, when they totaled 58,733 (fifty-eight thousand seven hundred thirty-three) servers, these 2.15% (two point fifteen percent) occupy commissioned positions, corresponding to 1,262 commissioned positions under the Direct Administration, below the national average of 4% (four percent). Of total commissioned positions 64.7% (sixty-four point seven percent) have no functional link with the direct administration, while only 35.3% (thirty -five point three percent) have functional link. It was noticed that there are no clear and specific criteria for the appointments of commissioned positions in the State. They occur freely, as provided in the State Constitution. Another conclusion is the importance of Public Administration define and improve their capacity, competence and efficiency in the delivery of public services. For that it is necessary to invest in their workforce composed of permanent employees and commissioned positions to define the appropriate professional profile

História, memória e espaços: experiências dos ex-combatentes de Parelhas-RN na defesa do litoral brasileiro durante a Segunda Guerra Mundial

The present essay has how I aim to analyse the memories of the ex-combatants of Parelhas-RN, specially of the components of the Força de Vigilância e Segurança do Litoral - FVSL, protagonists of the Brazilian participation in the scenery of the Second World war. Along this we looked to understand in which surrounding geographicalpartner these men were living before the War and what were the consequences of a brusque change of space owing to the convocation for the Armed Brazilian Strength in that historical context. The defense of the Brazilian coast during the War was not a so simple task, I have in mind the precariedade logistics of the Armed Strength, the attacks of submarines of the Axle that killed hundreds of civilians and Brazilian soldiers and the net of espionage mounted by Germany in Brazil. Leaving from the notion of collective memory and estrangement in Maurice Halbwachs, we will use the oral history like principal methodology, with the end of rescue these underground memories what also will make possible us the vision realizes that the protagonists themselves have of the event, besides the use of documents, photos, maps and any sort of fountains that make possible us to rebuild the scenery of Parelhas in the beginning of the War and the trajectory of life of his veterans

O afeto além dos muros e portões : o apego a vizinhanças na cidade do Natal

Place Attachment is a positive affective bond between people and environments, and its main characteristic is the desire to maintain closeness to the place of attachment. Neighborhoods, in turn, are spaces close to the dwelling, which varies according to environmental, social and cultural characteristics. Facing the contemporary scenario of diminishment of neighborhood relations and its importance to the understanding of cities social-environmental context, the present work aimed to investigate the attachment to neighborhoods at the city of Natal-RN. This study had two stages. The first stage consisted on investigating, through an experts panel, the main characteristics of attached neighborhoods, aspects that contributes to the development of these neighborhoods, the ones that difficult, as well as look for indications of neighborhoods at the city of Natal that may be identified by these elements. In the following stage I interviewed 11 residents of two indicated neighborhoods at the district of Alecrim, to better comprehend the main characteristics of this attachment and the elements of the context that enable its development. The content of the interviews, categorized and evaluated by judges, indicated that, due to the 10 participant experts, the main characteristics of attached neighborhoods encompass elements of socialization, cooperation, physical space usage, intimacy and identity. According to them, these are characteristics enabled by temporal and rootedness aspects, by spatial contact, familiarity between neighbors, and cultural inheritance. The interviews with residents showed that attachment to the studied neighborhoods is specially grounded on support and cooperation networks between neighbors, on satisfaction with the proximity of services, and on the bond to symbolic aspects and local traditions. In addition to be enabled by spatial organization, by low displacement of residents, and by the district s history, relations at these neighborhoods are fostered by an intention to establish this kind of ties, carried by cultural values

Preparation, characterization, and CuX2 and CoX2 (X = Cl-, Br-, ClO4-) adsorption behavior of a polyhedral oligomer silsesquioxane functionalized with an organic base

In this paper we report on the synthesis, characterization, and adsorption properties of the first 3-amino-1,2,4-triazole-modified porous silsesquioxane (ATPS). The isotherms of adsorption of MX2 (M = Cu(II), Co(II); X = Cl-, Br-, ClO4-) by ATPS were studied in ethanol and aqueous solutions at 298 K. The results showed that there is a good fit between the experimental data and the Langmuir isotherm. The adsorption capacity in both solvents followed the sequence Cu(II) >> Co(II). The lowest adsorption for Co(II) should be related to the largest hydration volume, which obstructs the adsorption capacity of the surface, and consequently causes a decrease in the number of cations adsorbed. For the salts with different anions the sequence was MCl2 > MBr2 > M(ClO4)2 in both solvents. The low affinity for M(ClO4)(2) toward the solid phase is a consequence of the poorer coordination ability of the ClO4-. Adsorptions from ethanol solutions were higher than those from aqueous solutions due to the higher polarity of water, which can more strongly solvate the solute and the basic sites on the surface. The following adsorption capacities (in mmol g(-1)) were determined: 0.24 (aq) and 0.84 (eth) for CuCl2, 0.09 (aq) and 0.16 (eth) for CuBr2, and 0.08 (aq) and 0.11 (eth) for Cu(ClO4)(2); 0.02 (aq) and 0.07 (eth) for CoCl2, 0.02 (aq) and 0.06 (eth) for CoBr2, and 0.01 (aq) and 0.05 (eth) for Co(ClO4)(2).

Adsorption of CuX2 (X = Cl-, Br-, and ClO4-) on a silica gel surface chemically modified with thiazolidine-2-thione from acetone and ethanol solutions

The isotherms of adsorption of CuX2 (X = Cl-, Br, ClO4-,) by silica gel chemically modified with thiazolidine-2-thione were studied in acetone (ac) and ethanol (eth) solutions at 25 degrees C. The following equilibrium constants (in 1 mol(-1)) were determined: a) CuCl2, 1.9 x 10(3) (ac), 1.6 x 10(3) (eth); b) CuBr2, 1.7 x 10(3) (ac), 1.2 x 10(3) (eth); c) Cu(ClO4)(2), 1.1 x 10(3) (ac), 1.0 x 10(3) (eth). The electron spin resonance spectra of the surface complexes indicate a tetragonal distorted structure in the case of lower degrees of metal loading on the chemically modified surface. The d-d electronic transition spectra show that for the ClO4- complex, the peak of absorption did not change for any degree of metal loading, and for Cl- and Br complexes, the peak maxima shift to higher energy with lower metal loading.

Inibição à corrosão do aço AISI 1020, em meios ácido e salino, por tensoativos e substâncias nitrogenadas microemulsionados

Corrosion inhibition efficiency of saponified coconut oil (SCO) and sodium dodecilbenzene sulfonate (DBS) surfactants in AISI 1020 carbon steel was evaluated by electrochemical methods. These surfactants were also evaluated as microemulsion systems (SCO-ME and DBS-ME), of O/W type (water-rich microemulsion), in a Winsor IV region. They were obtained according to the following composition: 15% SCO, 15% butanol (30% Co-surfactant/Surfactant C/T), 10% organic phase (FO, kerosene) and 60% aqueous phase (FA). These systems were also used to solubilize the following nitrogenated substances: Diphenylcarbazide (DC), 2,4-dinitro-phenyl-thiosemicarbazide (TSC) and the mesoionic type compound 1,3,4-triazolium-2-thiolate (MI), that were investigated with the purpose of evaluating their anticorrosive effects. Comparative studies of carbon steel corrosion inhibition efficiencies of free DBS and DBS-ME, in brine and acidic media (0.5%), showed that DBS presents better inhibition results in acidic media (free DBS, 89% and DBS-ME, 93%). However, the values obtained for DBS in salted solution (72% free DBS and 77% DBS-ME) were similar to the ones observed for the SCO surfactant in brine (63% free SCO and 74% SCO-ME). Analysis of corrosion inhibition of the nitrogenated substances that were solubilized in the SCO-ME microemulsion system by the linear polarization method in brine (0.5% NaCl) showed that such compounds are very efficient an corrosion inhibitors [DC-ME-SCO (92%), TSC-ME-SCO (93%) and MI-ME-SCO (94%)]

Acoustic and psychoacoustic analysis of the noise produced by the police force firearms

Police officers are exposed to impact noise coming from firearms, which may cause irreversible injuries to the hearing system.Aim: To evaluate the noise exposure in shooting stands during gunfire exercises, to analyze the acoustic impact of the noise produced by the firearms and to associate it with tonal audiometry results.Study design: Cross-sectional.Materials and methods: To measure noise intensity we used a digital sound level meter, and the acoustic analysis was carried out by means of the oscillations and cochlear response curves provided by the Praat software. 30 police officers were selected (27 males and 3 females).Results: The peak level measured was 113.1 dB(C) from a .40 pistol and 116.8 dB(C) for a .38 revolver. The values obtained for oscillation and Praat was 17.9 +/- 0.3 Barks, corresponding to the rate of 4,120 and 4,580 Hz. Audiometry indicated greater hearing loss at 4,000Hz in 86.7% of the cases.Conclusion: With the acoustic analysis it was possible to show cause and effect between the main areas of energy excitation of the cochlea (Praat cochlear response curve) and the frequencies of low hearing acuity.

AutoWebS: um Ambiente para Modelagem e Geração Automática de ServiçosWeb Semânticos

Typically Web services contain only syntactic information that describes their interfaces. Due to the lack of semantic descriptions of the Web services, service composition becomes a difficult task. To solve this problem, Web services can exploit the use of ontologies for the semantic definition of service s interface, thus facilitating the automation of discovering, publication, mediation, invocation, and composition of services. However, ontology languages, such as OWL-S, have constructs that are not easy to understand, even for Web developers, and the existing tools that support their use contains many details that make them difficult to manipulate. This paper presents a MDD tool called AutoWebS (Automatic Generation of Semantic Web Services) to develop OWL-S semantic Web services. AutoWebS uses an approach based on UML profiles and model transformations for automatic generation of Web services and their semantic description. AutoWebS offers an environment that provides many features required to model, implement, compile, and deploy semantic Web services

Influência do horário de colheita sobre o rendimento e composição do óleo essencial de erva-cidreira brasileira [Lippia alba (Mill.) N. E. Br.]

Este trabalho teve como objetivo verificar se o horário de colheita da erva-cidreira brasileira [Lippia alba (Mill.) N. E. Br.], fenotipo carvona-limoneno, tem influência sobre a produção de massa foliar, rendimento e composição do óleo essencial. Foram avaliados cinco horários de colheita quando a cultura estava com 145 dias desde o transplante: 8:00, 10:00, 12:00, 14:00 e 16:00 h com cinco repetições, distribuídos em blocos casualizados. O experimento foi conduzido na Fazenda Experimental Lageado da FCA-UNESP/Botucatu no Setor de Horticultura do Departamento de Produção Vegetal. A colheita foi realizada a 15 cm da superfície do solo e o óleo essencial obtido através de hidrodestilação, em aparelho tipo Clevenger. Levou-se em consideração os fatores agronômicos e o rendimento obtido por hidrodestilação. O óleo essencial foi analisado em cromatógrafo gasoso acoplado a espectrômetro de massas (CG/EM). Os resultados foram submetidos à análise de variância (Teste F) e as médias comparadas pelo teste de Tukey. Não houve diferença estatística para produção de massa foliar, teor de óleo essencial e produtividade de óleo essencial em massa fresca e seca. No entanto, entre os compostos majoritários do óleo essencial das folhas, carvona e limoneno, a melhor produtividade de carvona foi obtida às 10:00 h, em matéria fresca (2,050 L ha-1) e em matéria seca (2,068 L ha-1), e para o limoneno às 16:00 h, em matéria fresca (1,068 L ha-1) e em matéria seca (1,060 L ha-1).
