These general conceptual metaphors had been unfolded in other s more specific ones ( animal specifying itself in lion , dragon , dog , etc.). Another result was the identification of metaphoric expressions with two or more meanings , with relation to more than one conceptual metaphor or explicit, in the same expression, two domains-source (for example: armored dragon ) and contributes, of a relevant form, for the semantic struturation of the text. The understanding of the metaphors was verified through an activity of domains-source s identification (10 metaphoric statements and fulfilling of the gap in the phrase the inflation is a/an ) applied in a group of 8th year of the basic education (12-13 years old, with 14 girls and 17 boys) from a school of good social and economic positions from Natal-RN. There weren t great difficulties on the part of the students in recognizing the domains-source involved: about 80% to the great majority of the statements / A pesquisa visou a dois objetivos: 1?) identificar e descrever as met?foras da infla??o, em um corpus de 18 textos de jornalismo econ?mico, de autoria de Joelmir Beting, escritos no ?ltimo trimestre de 2002, no momento da transi??o do governo do presidente Fernando Henrique Cardoso para o do presidente eleito Luiz In?cio Lula da Silva. 2?) verificar o reconhecimento das met?foras por parte de alunos do ensino fundamental de uma escola particular de Natal. Foram identificadas 91 met?foras, analisadas na perspectiva da teoria da met?fora conceitual, de Lakoff e Johnson (2002), com base na distin??o entre met?fora conceitual / express?es metaf?ricas, e entre dom?nio-fonte / dom?nio-alvo. Foram depreendidas 10 met?foras conceituais subjacentes, sendo que os dom?nios-fonte mais freq?entemente utilizados para caracterizar a infla??o foram aqueles ligados ao ser humano e aos animais e, de forma menos previs?vel, aos meios de transporte (carro, aeronave). Essas met?foras conceituais gerais, foram desdobradas em outras mais espec?ficas ( animal especificando-se em le?o , drag?o , cachorro , etc.). Um outro resultado foi a identifica??o de express?es metaf?ricas poliss?micas , que remetem a mais de uma met?fora conceitual ou explicitam, na mesma express?o, dois dom?nios-fonte (por exemplo: drag?o blindado ) e contribuem, de forma relevante, para a estrutura??o sem?ntica do texto. A compreens?o das met?foras foi verificada atrav?s de uma atividade de identifica??o de dom?nios-fonte (10 enunciados metaf?ricos e preenchimento da lacuna na frase A infla??o ? um/uma... ) aplicada em uma turma de 8? ano do ensino fundamental (12-13 anos de idade, sendo 14 meninas e 17 meninos) de uma escola de classe m?dia-alta de Natal-RN. N?o houve maiores dificuldades por parte dos alunos em reconhecer os dom?nios-fonte envolvidos: em torno de 80% para a grande maioria dos enunciados

Tomo por base, especificamente, a Teoria Neural da Linguagem (FELDMAN, 2006) e, em conson?ncia com esse arcabou?o te?rico-metodol?gico, utilizo as no??es de categoriza??o (LAKOFF; JOHNSON, 1999), corporalidade (GIBBS, 2005), figuratividade (GIBBS, 1994; BERGEN, 2005) e simula??o mental (BARSALOU, 1999; FELDMAN, Ibid.). A hip?tese defendida ? a de que a constru??o da figuratividade em textos constitu?dos por mecanismos verbais e n?o verbais est? atrelada ? ativa??o de estruturas neurais relacionadas a nossas a??es e percep??es. Desse modo, a linguagem ? considerada uma faculdade cognitiva ligada ao aparato cerebral e ?s experi?ncias corp?reas, de maneira que ela fornece amostras do processo cont?nuo de (re)constru??o de sentidos efetivado pelo leitor, o qual (re)define suas vis?es acerca do mundo ? medida que certas redes neurais s?o (ou deixam de ser) ativadas durante o processamento lingu?stico. Dados obtidos na an?lise apontam que, no tocante ?s hist?rias em quadrinhos, a leitura dos recursos gr?ficos integrada ? da linguagem verbal parece ter um papel importante na constru??o de met?foras e de meton?mias, havendo casos, inclusive, de met?foras metonimicamente motivadas. Essas conclus?es adv?m da an?lise de dados retirados da obra V de vingan?a (MOORE; LLOYD, 2006). O estudo do corpus ? pautado na metodologia da introspec??o, isto ?, a an?lise individual dos aspectos lingu?sticos conforme se manifestam na pr?pria cogni??o do sujeito (TALMY, 2005). / The object of this study is the construction of metaphor and metonymy in comics. This work is inserted in the field of Embodied Cognitive Linguistics, specifically based on the Neural Theory of Language (FELDMAN, 2006) and, consistent with this theoretical and methodological framework, the notions of categorization (LAKOFF & JOHNSON, 1999), embodiment (GIBBS, 2005), figurativity (GIBBS, 1994; BERGEN, 2005), and mental simulation (BARSALOU, 1999; FELDMAN, 2006) have also been used. The hypothesis defended is that the construction of figurativity in texts consisting of verbal and nonverbal mechanisms is linked to the activation of neural structures related to our actions and perceptions. Thus, language is considered a cognitive faculty connected to the brain apparatus and to bodily experiences, in such a way that it provides samples of the continuous process of meaning (re)construction performed by the reader, whom (re)defines his or her views about the world as certain neural networks are (or stop being) activated during linguistic processing. The data obtained during the analysys shows that, as regards comics, the act of reading together the graphics and verbal language seems to have an important role in the construction of figurativity, including cases of metaphors which are metonymically motivated. These preliminary conclusions were drawn from the data analysis taken from V de Vingan?a (MOORE; LLOYD, 2006). The corpus study was guided by the methodology of introspection, i.e., the individual analysis of linguistic aspects as manifested in one's own cognition (TALMY, 2005).

Inicialmente aplicaram-se os modelos de regress?o log?stica e de Poisson para identificar as intera??es entre os extremos de precipita??o e as demais vari?veis a partir das raz?es de chances e de riscos relativos. Constatou-se que a vari?vel indicadora da ocorr?ncia de extremos de precipita??o ? a radia??o de onda longa, verificada nas regi?es leste, norte e semi?rido do NEB, e a umidade relativa foi verificada no sul do NEB, em ambos os modelos. Os resultados apresentados pelos modelos de regress?o log?stica e de Poisson mostram evid?ncias de que estes extremos de precipita??o s?o impulsionados pela Oscila??o Madden-Julian, que ao interagir com os outros sistemas meteorol?gicos locais, regionais e grande escala podem ocasionar a ocorr?ncia destes extremos. O terceiro modelo, MVLG-GEV, avaliou os extremos a partir dos m?ximos anuais de precipita??o de forma m?ltipla (a partir de um conjunto de vari?veis) e constatou-se que as vari?veis que subsidiaram a ocorr?ncia dos extremos de precipita??o foram: as componentes zonal e meridional do vento, evapora??o e TSM (Atl?ntico e Pac?fico). Este artigo mostra evid?ncias de que a variabilidade da TSM vistas no Atl?ntico como no Pac?fico (El Ni?o-Oscila??o Sul) interfera na variabilidade interanual da precipita??o, modificando o padr?o de circula??o atmosf?rica na regi?o, resultando na intensifica??o ou inibi??o da ocorr?ncia dos extremos de precipita??o. Os coeficientes de regress?o log?stica, de Poisson e de MVLG-GEV demonstraram signific?ncia estat?stica, inferiores a 5%. Em rela??o aos n?veis de retorno para os pr?ximos 30 anos pelos MVLG-GEV, o menor n?vel foi de 91,62mm no sul da Bahia, enquanto o maior foi de 185,72mm no norte do Cear?. / In this thesis used four different methods in order to diagnose the precipitation extremes on Northeastern Brazil (NEB): Generalized Linear Model s via logistic regression and Poisson, extreme value theory analysis via generalized extre me value (GEV) and generalized Pareto (GPD) distributions and Vectorial Generalized Linea r Models via GEV (MVLG GEV). The logistic regression and Poisson models were used to identify the interactions between the precipitation extremes and other variables based on the odds ratios and relative risks. It was found that the outgoing longwave radiation was the indicator variable for the occurrence of extreme precipitation on eastern, northern and semi arid NEB, and the relative humidity was verified on southern NEB. The GEV and GPD distribut ions (based on the 95th percentile) showed that the location and scale parameters were presented the maximum on the eastern and northern coast NEB, the GEV verified a maximum core on western of Pernambuco influenced by weather systems and topography. The GEV and GPD shape parameter, for most regions the data fitted by Weibull negative an d Beta distributions (? < 0) , respectively. The levels and return periods of GEV (GPD) on north ern Maranh?o (centerrn of Bahia) may occur at least an extreme precipitation event excee ding over of 160.9 mm /day (192.3 mm / day) on next 30 years. The MVLG GEV model found tha t the zonal and meridional wind components, evaporation and Atlantic and Pacific se a surface temperature boost the precipitation extremes. The GEV parameters show the following results: a) location ( ), the highest value was 88.26 ? 6.42 mm on northern Maran h?o; b) scale ( ? ), most regions showed positive values, except on southern of Maranh?o; an d c) shape ( ? ), most of the selected regions were adjusted by the Weibull negative distr ibution ( ? < 0 ). The southern Maranh?o and southern Bahia have greater accuracy. The level period, it was estimated that the centern of Bahia may occur at least an extreme precipitatio n event equal to or exceeding over 571.2 mm/day on next 30 years.

O corpus deste estudo ? constitu?do por seis cole??es de livros did?ticos de L?ngua Portuguesa inscritas no Guia do Programa Nacional do Livro Did?tico (PNLD) do ano de 2010, adotadas por escolas p?blicas do munic?pio de Natal e objeto de estudo no ?mbito do Projeto Ler/Contar do Observat?rio de Educa??o da Universidade Federal do Rio Grande do Norte (UFRN). Foram analisados os livros dos 4? e 5? anos do Ensino Fundamental, totalizando 12 exemplares. Selecionamos para an?lise dezesseis propostas de escrita de textos injuntivos. Para fundamentar nosso estudo, recorremos ? discuss?o te?rica de Adam (2001a, 2001b) no que diz respeito aos g?neros discursivos da incita??o ? a??o. Ainda, acompanhamos Koch e F?vero (1987), Koch e Elias (2009), Marcuschi (2003, 2008), Pery-Woodly (2001), Rodrigues (2013), Travaglia (1992, 2007) e Rosa (2007), no que concerne ? organiza??o material dos textos injuntivos. No que se refere ?s discuss?es sobre o livro did?tico, amparamo-nos em Choppin (2004, 2009), Batista (2003, 2009), Rojo e Batista (2005), e quanto aos livros did?tico de L?ngua Portuguesa, adotamos Soares (1998, 2001, 2004) e Bunzen e Rojo (2005). As propostas de escrita de textos injuntivos, nas cole??es analisadas, resumem-se a dicas/recomenda??es, instru??es para confec??o de brinquedos e/ou brincadeiras, roteiro de viagem e receita culin?ria, sendo que 69% delas aparecem nos livros dos 4? anos e apenas 31%, nos livros de 5? ano. No que concerne aos elementos lingu?sticos respons?veis pela constru??o dos atos de fala diretivos e os efeitos de sentido por eles produzidos, os dados nos mostram que 50% das propostas de escrita n?o exploram categorias lingu?sticas que imprimam os efeitos de sentido da injun??o, ou seja, inexiste um trabalho voltado ? an?lise lingu?stica, enquanto 33% mencionam o modo imperativo e 17% exploram verbos no infinitivo. Nesta disserta??o foram abordados os planos de texto dos g?neros da incita??o ? a??o e neles a materialidade lingu?stica que veicula o sentido da injun??o, estudo que pode contribuir com a melhoria do ensino de l?ngua portuguesa no que concerne ? articula??o dos estudos gramaticais ?s sequ?ncias/tipos textuais, principalmente nos livros did?ticos de Portugu?s para os anos iniciais do Ensino Fundamental. / This investigation aims at identifying, describing, analyzing and interpreting how textbooks on Portuguese Language approach, beginning with the linguistic material, the effects of sense in texts that predominately employ injunctives. The corpus of this study is comprised of six collections of textbooks on Portuguese Language, which are part of the National Program Guide for Textbooks (PNLD) from 2010, adopted by the public schools in the city of Natal and the object of study for the Read/Tell Project of the Educational Observatory of the Federal University of Rio Grande do Norte (UFRN). Textbooks from the 4th and 5th grades, Elementary School, were analyzed ? 12 copies total. For the analysis, we selected 16 writing proposals of injunctive texts. Our study is based on theoretical discussions by Adam (2001a, 2001b) with regard to the genre of: inciting to action. In addition, we consider the work of Koch and F?vero (1987), Koch and Elias (2009), Marcuschi (2003, 2008) Pery-Woodly (2001), Rodrigues (2013), Travaglia (1992, 2007) and Rosa (2007). With respect to discussions on textbooks, we refer to Choppin (2004, 2009), Batista (2003, 2009), Rojo e Batista (2005), and with regard to Portuguese Language textbooks specifically, we consider Soares (1998, 2001, 2004) and Bunzen and Rojo (2005). The proposals for writing in injunctive texts, in the collections analyzed, are tips/recommendations, instructions on making toys and/or games, travel itineraries and cooking recipes, such that 69% of them appear in the 4 th grade textbooks and only 31% appear in the 5th grade textbooks. With respect to the linguistic elements responsible for the construction of directive speech acts and the effects on sense produced by them, the data shows that 50% of the writing proposals do not exploit linguistic categories that implicate the effects on sense using injunctives, or rather, there is no work done dealing with linguistic analysis, while 33% mention the imperative mode and 17% investigate infinitive verbs. In this dissertation, the textual plans of incitation to act genres were studied and in them the linguistic materiality that vehicles injunction. This study might contribute to the improvement of Portuguese language teaching in what concerns the articulation of grammatical studies to textual sequences/types, mainly in the case of Portuguese language textbooks for the 4th and 5th grades of Elementary School.

Este aumento est? relacionado ao descarte de efluentes contendo teores desses elementos acima do valor m?ximo permitido por lei. M?todos como troca i?nica, filtra??o por membranas e precipita??o qu?mica vem sendo estudados como meios de tratamentos de efluentes contaminados por esses metais. A precipita??o de metais utilizando tensoativos ani?nicos obtidos a partir de ?cidos carbox?licos surgiu como uma alternativa para a remo??o de metais de efluentes industriais. A rea??o entre ?ons bivalentes dos metais e esses tipos de tensoativos em solu??o aquosa leva a forma??o de carboxilatos de metais, que podem precipitar na forma de flocos e serem removidos, posteriormente, por um processo de decanta??o dos flocos formados ou por uma filtra??o simples. Neste trabalho, a extra??o de metais ? realizada por meio da utiliza??o do tensoativo hexadecanoato de s?dio como agente extrator. O objetivo principal ? estudar o efeito da varia??o da temperatura do meio, pH da solu??o de metal e concentra??o do tensoativo no processo de remo??o do metal. A modelagem estat?stica do estudo mostrou que o processo ? diretamente dependente das varia??es de pH e concentra??o do tensoativo, por?m inversamente proporcional e pouco dependente da varia??o de temperatura, sendo esse ?ltimo efeito considerado desprez?vel na maioria dos casos. O estudo individual do efeito da temperatura apresenta uma forte depend?ncia do processo ? temperatura de Kraft, tanto do tensoativo utilizado como agente extrator como do tensoativo obtido ap?s a rea??o desse tensoativo com o metal. A partir dos dados de temperaturas e concentra??es do tensoativo foi poss?vel o c?lculo da constante de equil?brio para a rea??o entre o hexadecanoato de s?dio e ?ons cobre. Posteriormente, foram determinados par?metros termodin?micos, comprovando que o processo ? exot?rmico e espont?neo. / Industrial activities like mining, electroplating and the oil extraction process, are increasing the levels of heavy metals such as Cu, Fe, Mg and Cd in aquatic ecosystems. This increase is related to the discharge of effluents containing trace of this elements above the maximum allowed by law. Methods such as ion exchange, membrane filtration and chemical precipitation have been studied as a means of treatment of these metals contamination. The precipitation of metals using anionic surfactants derived from carboxylic acids emerged as an alternative for the removal of metals from industrial effluents. The reaction between bivalent ions and these types of surfactants in aqueous solution leads to the formation of metal carboxylates, which can precipitate in the form of flakes and are subsequently removed by a process of decantation or simple filtration. In this work the metals extraction is performed by using the surfactant sodium hexadecanoate as extracting agent. The main purpose was to study the effect of temperature, solution pH, and concentration of surfactant in the metal removal process. The statistical design of the process showed that the process is directly dependent to changes in pH and concentration of surfactant, but inversely proportional and somewhat dependent to temperature variation, with the latter effect being considered negligible in most cases. The individual study of the effect of temperature showed a strong dependence of the process with the Kraft point, both for the surfactant used as extracting agent, as for the surfactant obtained after the reaction of this surfactant with the metal. From data of temperatures and concentrations of the surfactant was possible to calculate the equilibrium constant for the reaction between sodium hexadecanoate and copper ions. Later, thermodynamic parameters were determined, showing that the process is exothermic and spontaneous.

Sua distribui??o ? pantropical com grande frequ?ncia em ambientes sazonalmente secos. Seus representantes apresentam h?bito arb?reo, arbustivo e raramente lianescente, folhas simples ou compostas 3-folioladas, br?cteas florais reduzidas e dec?duas, flores tetr?meras e noturnas com estames exsertos numerosos, ov?rio s?pero sobre um gin?foro, frutos carnosos deiscentes ou indeiscentes. Para o Brasil s?o registrados 12 g?neros e 28 esp?cies das quais 12 s?o end?micas do pa?s, ocorrendo preferencialmente em savana est?pica (strictu senso), floresta estacional semidecidual e restinga. O presente trabalho est? dividido em dois cap?tulos. O primeiro cap?tulo aborda o padr?o de distribui??o das esp?cies que ocorrem no semi?rido brasileiro e sua distribui??o intra Caatinga. Os padr?es de distribui??o foram determinados a partir da revis?o da distribui??o das esp?cies em cole??es de herb?rios e complementados com dados obtidos de bibliografia espec?fica da fam?lia. Foram avaliadas a riqueza, esfor?o de coleta e similaridade flor?stica das esp?cies intra Caatinga pelo m?todo de quadr?culas de 1 ? 1 grau. Seis g?neros e oito esp?cies foram registradas na Caatinga, sendo quatro end?micas do Brasil, dessas, apenas uma ? end?mica da Caatinga, e quatro apresentaram distribui??o neotropical. Quatro padr?es foram observados: restrito ao NE, amplo e cont?nuo no Brasil, disjunto e neotropical. Todas as esp?cies foram registradas na Bahia, estado que apresentou a maior riqueza de esp?cies por quadr?cula e tamb?m not?vel esfor?o amostral das esp?cies da fam?lia. O estado do Piau? apresenta ?reas priorit?rias para futuras coletas de Capparaceae, devido a pouca representatividade da fam?lia no estado. A an?lise de similaridade flor?stica intra Caatinga mostrou-se baixa, 22%, provavelmente devido a poucas esp?cies da fam?lia na regi?o e a ampla distribui??o das mesmas. No segundo cap?tulo ? apresentada a flora de Capparaceae para o Rio Grande do Norte (RN), visto que o estado possui uma flora pouco conhecida, com estudos pontuais. Atrav?s de coletas no estado e revis?o de herb?rio foram registrados cinco g?neros e seis esp?cies de Capparaceae no RN: Capparidastrum (1); Crateva (1); Cynophalla (2); Mesocapparis (1) e Neocalyptrocalyx (1). Capparidastrum frondosum e Mesocapparis lineata s?o novas ocorr?ncias para o estado. S?o apresentadas uma chave de identifica??o, descri??es e imagens, coment?rios sobre a biologia das esp?cies e Unidades de Conserva??o onde ocorrem. / Capparaceae comprises 25 genera and 480 species, of which 110 are included in 18 genera in Neotropics. Its distribution is pantropical with high frequency in seasonally dry environments. Its representatives are woody, shrubs and rarely wines, with simple leave or compound 3-foliolate, shorts and deciduous floral bracts, tetramerous and nocturnal flowers with exserts and numerous stamens, ovary supero on a gynophore and fleshy fruits, dehiscents or indehiscentes. For Brazil, 12 genera and 28 species are recorded and 12 of that are endemic to the country, occurring preferentially in vegetation of savanna est?pica s.str., seasonal semideciduos forest and restinga. This work shows two chapters. In the first chapter, the distributions patterns of the species occurring in the brazilian semi-arid region and their distribution intra Caatinga are discussed. The distribution patterns were determined from a review of the distribution of species in herbaria collections and supplemented with data obtained from specific bibliography about the family. A map containing 1 ? 1 grid cells was used to evaluate the richness, collection efforts and floristic similarity of the species intra Caatinga. Six genera and eight species were registered in Caatinga. Four species are endemic to Brazil, with only one endemic to Caatinga, and the other four are widespread in Neotropics. Four distribution patterns were observed: restricted to the NE, broad and continuous in Brazil, disjunct and neotropical. All the species were recorded in Bahia, state with the highest species richness per grid cell and also remarkable sampling efforts species of the family. The state of Piau? presents priority areas for further collection of Capparaceae, due to low family representation in the state. The floristic similarity analysis intra Caatinga was low, 22 %, probably due to a few species of the family in the region and the wide distribution of the same. The second chapter presents the Capparaceae of flora to Rio Grande do Norte (RN), since the state has a little-known flora, with specific studies. Through collections in the state and herbaria review, five genera and six species of Capparaceae were recorded in RN: Capparidastrum (1 spp.); Crateva (1 spp.); Cynophalla (2 spp.); Mesocapparis (1 spp.) and Neocalyptrocalyx (1 spp.). Capparidastrum frondosum and Mesocapparis lineata are new records for the state. An identification key, descriptions and images, comments on the biology of the species and protected areas where they occur are showed.

Essa rela?c?ao ?e consistente com as teorias de perda de momentum angular atrav?es do vento estelar ionizado, que por sua vez est?a acoplado `a estrela pelo seu campo magn?etico. V?arios autores (e.g.: Silva et al. 2013 e de Freitas et al. 2014) analisaram as poss??veis correla?c?oes entre o decaimento rotacional e o perfil da distribui?c?ao de velocidade. Esses autores chegaram a uma simples rela?c?ao heur??stica, mas n?ao constru??ram uma passagem direta entre o expoente do decaimento rotacional (j) e o expoente da distribui?c?ao da velocidade rotacional (q). Todo esse cen?ario te?orico foi proposto usando uma eficiente e robusta mec?anica estat??stica bem conhecida como mec?anica estat??stica n?ao-extensiva. A presente disserta?c?ao prop?oe efetivamente fechar essa quest?ao, elaborando um caminho te?orico para modificar as distribui?c?oes q-Maxwellianas em q-Maxwellianas com v??nculos f??sicos extra??dos da teoria do freio magn?etico. Para testar nossas distribui?c?oes, usamos um pacote de dados do cat?alogo de Geneva-Copenhagem Survey com aproximadamente 6000 estrelas F e G limitadas em idade. Como resultado, obtivemos que os expoentes da lei de decaimento e da distribui?c?ao seguem uma rela?c?ao similar `aquela proposta por Silva et al. (2013). / The pioneering work proposed by Skumanich (1972) has shown that the projected mean rotational velocity < v sini > for solar type stars follows a rotation law decreases with the time given by t ?1/2 , where t is the stellar age. This relationship is consistent with the theories of the angular momentum loss through the ionized stellar wind, which in turn is coupled to the star through its magnetic field. Several authors (e.g.: Silva et al. 2013 and de Freitas et al. 2014) have analyzed the possible matches between the rotational decay and the profile of the velocity distribution. These authors came to a simple heuristic relationship, but did not build a direct path between the exponent of the rotational decay (j) and the exponent of the distribution of the rotational velocity (q). The whole theoretical scenario has been proposed using an efficient and strong statistical mechanics well known as non-extensive statistical mechanics. The present dissertation proposes effectively to close this issue by elaborating a theoretical way to modify the q-Maxwellians? distributions into q-Maxwellians with physics links extracted from the theory of magnetic braking. In order to test our distributions we have used the GenevaCapenhagen Survey data with approximately 6000 F and G field stars limited by age. As a result, we obtained that the exponents of the decay law and distribution follow a similar relationship to that proposed by Silva et al. (2013).

Especificamente, n?s consideramos os modelos de distribui??o de transi- ??o e mistura gaussianas (GMTD). Os modelos GMTD s?o uma classe mais geral do que os modelos da fam?lia autoregressiva (AR), no sentido de que os processos autocorrelacionados podem apresentar trechos planos (plat?s), explos?es ou outliers. Neste cen?rio os Gr?ficos de Shewhart tradicionais n?o s?o mais ferramentas adequadas para o acompanhamento desses processos. Portanto, Vasilopoulos e Stamboulis (1978) propuseram uma vers?o modificada dos gr?ficos, considerando limites de controle adequados com base em processos autocorrelacionados. A fim de avaliar a efici?ncia da t?cnica proposta uma compara??o com um gr?fico tradicional Shewhart (que ignora a estrutura de autocorrela??o do processo), o gr?fico de controle Shewhart AR(1) e um gr?fico de controle Shewhart GMTD foi feita. Uma express?o anal?tica para a vari?ncia processo, assim como os limites de controle foram desenvolvidos para um modelo GMTD particular. O ARL ? utilizado como crit?rio para medir a efici?ncia dos gr?ficos de controle. A compara??o foi feita com base em uma s?rie gerada de acordo com um modelo GMTD. Os resultados apontam para a dire??o que os gr?ficos modificados Shewhart GMTD t?m um melhor desempenho do que o Shewhart AR(1) e o Shewhart tradicional. / This work proposes a modified control chart incorporating concepts of time series analysis. Specifically, we considerer Gaussian mixed transition distribution (GMTD) models. The GMTD models are a more general class than the autorregressive (AR) family, in the sense that the autocorrelated processes may present flat stretches, bursts or outliers. In this scenario traditional Shewhart charts are no longer appropriate tools to monitoring such processes. Therefore, Vasilopoulos and Stamboulis (1978) proposed a modified version of those charts, considering proper control limits based on autocorrelated processes. In order to evaluate the efficiency of the proposed technique a comparison with a traditional Shewhart chart (which ignores the autocorrelation structure of the process), a AR(1) Shewhart control chart and a GMTD Shewhart control chart was made. An analytical expression for the process variance, as well as control limits were developed for a particular GMTD model. The ARL was used as a criteria to measure the efficiency of control charts. The comparison was made based on a series generated according to a GMTD model. The results point to the direction that the modified Shewhart GMTD charts have a better performance than the AR(1) Shewhart and the traditional Shewhart.

Os resultados revelaram a exist?ncia de diferentes configura??es em portugu?s para a constru??o medial, sendo a protot?pica a formada por SN+V. Do ponto de vista morfossint?tico e sem?ntico, a constru??o expressa um sujeito afetado por uma a??o que n?o parte dele. Quanto ao aspecto pragm?tico, a constru??o expressa um evento que parece ter como prop?sito enfatizar o argumento afetado e ignorar, intencionalmente ou n?o, o agente ou o causativo, por ser irrelevante para o falante/ouvinte na situa??o de comunica??o. / This thesis examines the medial construction of the Portuguese of Brazil (PB). It is a construction which describes a causative event in which a non-human subject participant is affected by an action that does not originate from itself. Thus, we are interested in investigating this type of construction, its specific characteristics, motivations and discursive context from its semantic- cognitive and discoursive - pragmatic functions. The research questions are: what is the prototypical structural configuration of the medial construction (MC) in the Portuguese of Brazil? What are its specific discoursive functions? What is the degree of MC transitivity based on the properties proposed by Hopper and Thompson (1980)? We assume that the medial construction has its own structure which particularizes its significant dimension, thus ensuring a certain distance between the one in charge of the event and the affected entity. The theoretical and methodological assumptions is founded on Usage-based Functional Linguistics (FURTADO DA CUNHA; BISPO; SILVA, 2013). It is a research of qualitative- interpretative nature that has prioritized the analysis of occurrences arising from texts produced by users of the Brazilian Portuguese language in effective communicative situation. The database for this study is electronic texts available on the website www.reclameaqui.com.br. The results revealed the existence of different configurations of the medial construction in the Brazilian Portuguese, having as prototypical the one formed by SN + V. From the morphosyntactic and semantic point of view, the construction expresses a subject affected by an action that does not part from itself. As for the pragmatic aspect, the construction expresses an event that seems to have the purpose to emphasize the affected argument and to ignore, intentionally or not, the agent or the causative, since it is irrelevant to the speaker/ listener in the contextual situation.

O corpus em an?lise se constitui de cartas de leitores, cartas de redatores e an?ncios de jornais brasileiros dos s?culos XIX e XX de diferentes regi?es/estados - Rio de Janeiro, Bahia, Cear? e Pernambuco - e pertencem ao corpus m?nimo comum do Projeto para a Hist?ria do Portugu?s Brasileiro (PHPB). A an?lise est? fundamentada em pressupostos te?rico-metodol?gicos da teoria da Varia??o e Mudan?a (WEINREICH; LABOV; HERZOG, 1968[2006]; LABOV, 1972[2008]), da teoria de Princ?pios e Par?metros (CHOMSKY, 1981; 1986) e do modelo de competi??o de gram?ticas (KROCH, 1989; 2001). Os resultados mostram que o contexto das senten?as infinitivas preposicionadas apresenta, de um modo geral, uma forte varia??o clV/Vcl durante os s?culos XIX e XX. Considerando o tipo de preposi??o, identificamos que, em todas as preposi??es, exceto nas senten?as com a e em, h? uma queda significativa das taxas de pr?clise na segunda metade do s?culo XIX.

Por fim, na segunda metade do s?culo XX, apesar do aumento da ocorr?ncia de pr?clise em senten?as com verbos precedidos pelas preposi??es por, a e de, as taxas de frequ?ncia de pr?clise nesses contextos n?o ultrapassam 50%. De um modo geral, os resultados referentes ?s ora??es completivas preposicionadas mostram um per?odo de forte instabilidade ao longo dos s?culos XIX e XX, ou melhor, uma forte varia??o entre anteposi??o e posposi??o do cl?tico ao verbo no infinitivo. Apesar de os resultados apontarem para uma diminui??o das ocorr?ncias de pr?clise no per?odo que vai dos s?culos XIX ao XX, vemos que a probabilidade de ocorr?ncia de pr?clise em senten?as com verbos regidos pelas preposi??es de, para, por e sem ? alta e significativa. / In this work we present the description and analysis of the clitics collocation patterns in prepositional infinitive sentences within the Brazilian writing in the centuries XIX and XX. The corpus in analysis is comprised of letters of newspaper readers and newspaper writers, as well as of advertisements (ads) taken from Brazilian newspapers from different regions / states ? Rio de Janeiro, Bahia, Cear? and Pernambuco ? and written in the Centuries XIX and XX. They belong to the common minimum corpus of the project named Projeto para a Hist?ria do Portugu?s Brasileiro (PHPB or Project to the History of the Brazilian Portuguese, in English). Its analysis is based on theoreticalmethodological postulates of the Theory of Variation and Change (WEINREICH; LABOV; HERZOG, 1968[2006]; LABOV, 1972[2008]); on the Theory of Principles and Parameters (CHOMSKY, 1981, 1986) and on the model of Grammar Competition (KROCH, 1989; 2001). By trying to articulate those presuppositions from both the theories we present a proposition of theoretical interface between the Variation Theory and the Grammar one. Concerning the empirical results achieved by means of this research, we could figure that, in the context in which there were prepositional infinitive sentences, the most significant independent variable to the occurrence of the proclisis is the type of preposition that comes before the verb in the infinitive. Before that, we found out that there are prepositions which strongly direct the proclisis, as it is the case of the prepositions in Portuguese sem, por, de and para, with all of them presenting Relative Weights over 0,52. Another important result is the one attested in the data referring the state of Rio de Janeiro (RJ). This state is the only one of the sample which is located in the Southeastern region and also presents itself as the main proclisis conditioner amongst the localities pertaining to the sample. In order to explain those results, we raised the hypothesis that the proclisis implementation may be more advanced in the Southeastern than in the Northeastern Brazil, however that hypothesis must be confirmed or refuted in future works. We also present, in this work, a theoretical explanation about the clitics colocation in prepositional infinitive sentences within the Brazilian writing in the XIX and XX centuries. The theoretical explanation we found to interpret the achieved results associates Magro?s proposition (2005), regarding the existence of prepositions occupying the nucleus PP and the existence of prepositions which can play the role of a completer and occupy the nucleus CP, according to Galves (2000; 2001), regarding the existent relation between the clitic colocation and the association of traits-phi to the functional categories COMP, Tense and Person. Our proposition is that the occurrence of prepositions which occupy the nucleus CP causes changes in the values attributed to the traits-phi and to the strong Vtraits in the functional categories COMP, Tense and Person. Thus, we defend that proclisis in Brazilian Portuguese (BP) is derived from the movement of the verb to the functional category tense in which there is the association of traits +V and traits +AGR, what legitimates the proclisis according to Galves?s proposition (2000; 2001).
