A compreens?o do mundo se d? por meio de uma leitura, de uma interpreta??o incessante dos contextos sociais. Essa compreens?o, assim como o mundo, est? em constante mudan?a e n?o h? raz?o para as interpreta??es atuais ficarem estagnadas por an?lises ultrapassadas. Compreender os discursos que movem o mundo, ? compreender as rela??es que se estabelecem nele. A an?lise de discurso promove as reflex?es necess?rias para o entendimento dessas rela??es e com isso, ? poss?vel atingir camadas ocultas onde n?o h? palavras escritas, onde o que existe ? o teor discursivo intang?vel, gerado por rela??es entre o poder, o saber, a verdade e o sujeito. A an?lise de um discurso pol?tico ? capaz de demonstrar o poder de coer??o dessas rela??es que atuam em conjunto e que atingem a sociedade. Ao analisarmos dois discursos pol?ticos proferidos por uma mesma pessoa em ?pocas diferentes, pudemos averiguar se a verdade do sujeito de ontem ainda ? a mesma do sujeito de hoje, mesmo n?o havendo uma mudan?a ideol?gica descrita no pr?prio discurso, pois, a verdade, pode sofrer muta??es conforme o tempo passa e o que antes era verdadeiro, pode ser o falso de hoje. Michel Foucault nos traz inquieta??es e contesta??es sobre a ordem do discurso, o que devemos considerar numa an?lise discursiva e m?todos de como essa investiga??o pode ser realizada. Em algumas de suas obras, a an?lise do poder e suas rela??es ? muito evidente e ? com base nessas acep??es que utilizamos a genealogia do poder de Foucault e nos empenhamos a analisar as rela??es de poder em dois discursos pol?ticos da posse de Arthur Virg?lio Neto, o primeiro ocorreu em 2013 e corresponde ao seu segundo mandato em sua carreira como prefeito de Manaus. J?, o segundo discurso ocorrido no dia primeiro de janeiro de 2017, refere-se ? sua reelei??o como prefeito. Ainda pudemos dar outro foco e realizar uma an?lise que evidenciou os modos de subjetividade de Arthur Virg?lio Neto, relatando-se nos dois discursos: o sujeito ainda ? o mesmo do discurso de 2013 ou n?o? E com isso, ratificar a import?ncia da an?lise do discurso e como ela ? capaz de questionar discursos dos mais diversos campos do saber.

The world comprehension occurs through a reading of an incessant interpretation of the social contexts. This comprehension, as well as the world, is constantly changing and there is no reason for current interpretations to be stagnant by outdated analysis. To understand these discourses that move the world, it is to understand the relationships that are established in it. Discourse analysis promotes the necessary reflections to understand these relations and makes it possible to reach hidden layers where there are no written words, where exists the intangible discursive content generated by relations between power, knowledge, truth and subjectivity. The analysis of a political discourse is able to demonstrate the coercive power of those relations that act together affecting society. The analysis of two political discourses uttered by the same person at different times, allow us to ascertain…

O presente trabalho teve como objetivo avaliar o efeito das diferentes ?pocas de plantio na din?mica populacional de insetos-praga e seus inimigos naturais da cultura do feij?o-caupi. O estudo foi realizado em tr?s ?pocas do ano, de setembro/2017 a agosto/2018 na Fazenda Experimental da Universidade Federal do Amazonas FAEXP. Foram realizadas amostragens semanais, totalizando 33 coletas. Utilizou-se para cada ?poca de plantio duas formas de coletas: avalia??o individual das plantas por metro linear em 10 pontos de coleta aleat?ria e rede entomol?gica (10 redadas em 10 pontos de coleta) conforme o est?dio fenol?gico da cultura. Por meio da an?lise faun?stica, realizada nas tr?s ?pocas de plantio, foi poss?vel verificar que Acromyrmex sp.; Agromyzidae sp. Cerotoma arcuata, Crinocerus sanctus, Euschistus heros, Horciasinus signoreti e Nezara viridula foram ?s esp?cies consideradas pragas da cultura do feij?o-caupi, merecendo destaque para H.signoreti por ter sido a primeira vez considerada predominante em plantios de feij?o-caupi no estado do Amazonas. Os inimigos naturais observados nas ?pocas analisadas s?o dos grupos dos parasitoides e predadores. Dentre os parasitoides, a fam?lia mais abundante foi Tachinidae (Diptera) e dos predadores, Dolichopodidae (Diptera), Syrphidae (Diptera) e Formicidae (Hymenoptera). No entanto, foi poss?vel verificar que n?o houve diferen?a significativa para o total de insetos-praga coletados entre as ?pocas estudadas. Por?m, adiantando ou atrasando a ?poca de plantio sempre haver? infesta??o dos hem?pteros: C. sanctus, N. viridula, E. heros e H. signoreti, embora, aparentemente, as esp?cies de percevejos relatadas como de import?ncia econ?mica, neste trabalho, demonstraram prefer?ncias por ?pocas espec?ficas com exce??o do H. signoreti que teve ocorr?ncia e foram dominantes nas tr?s ?pocas. Os maiores picos populacionais de hem?pteros ocorreram nos est?dios reprodutivos. A altera??o na ?poca de plantio proporcionou uma menor popula??o do inseto desfolhador de maior import?ncia econ?mica da cultura do feij?o-caupi, C. arcuata, na primeira e segunda ?poca e maior infesta??o na ?poca recomendada para o plantio (junho a agosto). A maior produ??o registrada foi na segunda ?poca de plantio, 420 kg, por?m com menor aproveitamento de gr?os secos devido ?s perdas ocasionadas por fatores diretos e indiretos durante o plantio. Portanto, se a inten??o for obter um melhor aproveitamento de gr?os secos e reduzir a infesta??o de C. arcuata, sugere-se que o plantio seja realizado de forma mais tardia, pois, dessa forma, os danos ocasionados por essa praga tendem a ser em menores propor??es devido ? baixa infesta??o desses insetos nessa ?poca de plantio.

One of the great challenges of Accounting Sciences is to contribute to the reality of new fields of study; Is the case, for example, of the environmental issue. This study aimed to know and analyze the disclosure criteria in accounting statements and explanatory notes from this perspective .With a long tradition of exclusively financial reports, companies have come to realize that in drawing up sustainability reports, they find a way to reflect and internalize the issue, as well as to make their own vision,challenges and economic, social and environmental results public in the field of construction.And how these actions reflect on their results. The procedures used for data collection were documental research and motivated by its accessibility. We analyzed a set of annual financial statements and explanatory notes published in the period between 2011 and 2015.

▼ Previous studies on corporate divestiture in international publications have documented that operations with poor operating performance, financial difficulties or with low investment levels are significant determinants of corporate divestment decisions. They also consider that larger companies, firm age and firms that had previous experience in divestment are more prone to new divestitures. The hypotheses were formulated based on previous results and the research was developed to identify the determinants of divestment for a sample of 161 Brazilian companies for the period from 2004 to 2015 with 352 divestiture events. The findings are consistent with the proposition that firm size and prior divestitures experience are significant determinants of divestitures. As a surprise, the results do not support the hypotheses that poor operating performance, leverage, lower investment level and firm age as determinants of divestiture activities. This study provides an introduction to the topic of corporate divestiture and its determinants in the national academic context.

Na presente disserta??o apresentamos uma nova abordagem para aplica??es em An?lise Discriminante (AD) para problemas cujas observa??es no conjunto de treinamento s?o oriundas de s?ries temporais, empregando o Classificador de Bayes e modelando as distribui??es nas classes com o emprego de Modelos Lineares Din?micos. Foram realizados os desenvolvimentos te?ricos necess?rios para a obten??o de uma forma anal?tica para as probabilidades a posteriori das classes. Para avaliar a abordagem proposta foram desenvolvidos estudos de simula??o, tanto para avaliar as estrat?gias da escolha do procedimento da estima??o da vari?ncia, como tamb?m, determinar as taxas de erro (TE) de classifica??o para compar?-las com outras abordagens usuais para classificadores em AD. Foram simuladas observa??es de s?ries temporais com diferentes estruturas de separa??o das classes e com diferentes tamanhos para o conjunto de treinamento. A abordagem proposta tamb?m foi aplicada em dados de problemas reais, com diferentes graus de dificuldades com rela??o ao n?mero de classes, tamanho das s?ries e o n?mero de observa??es no conjunto de treinamento, sendo ent?o comparadas suas TE com as de outros classificadores. Embora sejam necess?rios estudos mais completos, os resultados obtidos sugerem que a abordagem param?trica desenvolvida se constitui em uma alternativa promissora para esta categoria de problemas em AD, com observa??es de s?ries temporais, em particular, em um contexto bastante desafiador na pr?tica quando temos s?ries com tamanhos grandes com rela??o ao n?mero de observa??es nas classes.

In this work we present a new approach for applications in Discriminant Analysis (DA) to problems whose observations in the training set are from time series, using the Bayes classifier and modeling the classes distributions in with Linear Dynamic Models. Theoretical developments were conducted to obtain an analytic form for the classe posterior probability. The simulation studies have been developed to evaluate the proposed approach, to evaluate different strategies to estimate the model variance and determine the classification error rates (ET) to compare them with other usual approaches in AD. Time series were simulated with different structures of classes separation and with different sizes for the training set. The proposed approach was also applied to data from real problems with different degrees of difficulty with respect to the classes number, the time series size and number of observations in the training set. With real data the proposed classifier was compared with other classifiers in terms of error rate. Although it is needed most complete studies, the results suggest that this parametric approach developed constitutes a promising alternative for problems in AD with time series, particularly in a challenging context when the size time series is much large than the number of observations in the classes.

Este trabalho tem por objetivo auxiliar alunos e professores em rela??o ? an?lise combinat?ria, que ? considerado como um dos mais complexos na matem?tica, pelo fato de exigir racioc?nio potencializado para a resolu??o de problemas. Por todas as dificuldades encontradas pelos alunos e professores em rela??o ? aprendizagem tanto pelas metodologias aplicadas quanto falta de continuidade do conte?do que somente ? aprendido no 2? ano do ensino m?dio, apresentamos conceitos dos t?picos de an?lise combinat?ria como Princ?pio Fundamental da Contagem, Permuta??es, Arranjos e Combina??es com v?rios problemas de aplica??es para melhor entendimento, al?m de t?picos n?o muito explanados no ensino b?sico como Princ?pio da Inclus?o-Exclus?o e Princ?pio das Gavetas de Dirichlet ou Princ?pio das Casas dos Pombos. Aproveitamos para apresentar problemas de olimp?adas de v?rios n?veis com solu??es de muitas maneiras. Atrav?s de an?lises dos PCN?s e de disserta??es do PROFMAT, comprovamos a import?ncia da an?lise combinat?ria e a sua defasagem em alunos do ensino m?dio, assim como a necessidade de seu ensino ainda no ensino fundamental.

This work aims to help students and teachers in the combinatorial analysis, which is considered one of the most complex in mathematics, because it requires a potentialized reasoning to solve problems. Due to all the difficulties encountered by students and teachers such as both applied methodologies learning and lack of continuity of content, for example, this is only learned in the 2nd year of high school, we present concepts of combinatorial analysis topics such as Fundamental Principle of Counting, Permutations, Arrangements and Combinations, associated with various application problems for better understanding, as well as topics not much explained in basic education such as Inclusion-Exclusion Principle and Dirichlet Drawer Principle or Pigeon Houses Principle. We take the opportunity to present Olympics problems in several levels with solutions in many ways. Through analysis of NCP's and PROFMAT dissertations, we have demonstrated the importance of combinatorial analysis and its lag in high school students, as well as the need for its teaching in elementary school.

Este estudo traz reflex?es sobre a An?lise do Discurso Francesa, ? luz de Michael Foucault, na maneira como se constituem os discursos de ?dio, fake news e p?s-verdade enunciados por Jair Bolsonaro entre os anos de 2013 e 2019 formulando regimes de verdade ou formas de veridc??o. Para isso, se faz necess?rio descrever a produ??o de sentidos que fizeram funcionar como verdadeiros na m?dia, sobretudo nas redes sociais de Jair Bolsonaro; apresentar de que forma as rela??es de poder e o discurso de ?dio se exercem sobre estatutos e procedimentos que s?o utilizados para a obten??o da verdade nas rela??es entre sujeito, discurso e sociedade relacionando-os a discursividades e considerando a constru??o do sujeito e das materialidades lingu?sticas coletadas. Apesar de todo esse contexto, compreender o que ? pol?tica parece ser um caminho assertivo para evitar que as discuss?es fiquem somente no ?mbito das polaridades partid?rias estimuladas pela fun??o das redes sociais como plataforma para novos porta-vozes. Nas materialidades lingu?sticas analisadas, ainda que mantenham v?nculos com dados factuais, inerente a toda constru??o ideol?gica, percebe-se enunciados contradit?rios e autorit?rios permitindo reativar sentidos que viabilizam a fragilidade da democracia.

This research brings reflections on the French Discourse Analysis according to Michael Foucault about Jair Bolsonaro's hate speech, fake news and post-truth discourses between 2013 and 2019 formulating truth regimes or veridiction means. For this, it is necessary to describe the production of meanings that made it work as true in the media, especially on Jair Bolsonaro's social networks; to present how power relations and hate speech are exerted on statutes and procedures that are used for the truth achievement in the relations between subject, discourse and society by relating them to discursivities and considering the construction of the subject and the collected linguistic materialities. In spite of all this context, understanding what politics is seems to be an assertive way to avoid that discussions are only within the scope of party polarities stimulated by the function of social networks as a platform for new spokespersons. In the linguistic materialities analyzed, although they maintain links with factual data, inherent in all ideological construction, it is perceived contradictory and authoritarian statements allowing to restore meanings that enable the fragility of democracy.

It used the Data Anvelopment Analysis (DEA) as a tool for analysis in the selection of investment portfolios based on stocks traded on Bovespa stock exchange. This methodology is based on non-parametric mathematical models that evaluate the performance of each Decision Making Unit (DMU) with a multidimensional perspective. This research selected a portfolio composed of 20 stocks, for which we obtained the efficiency indicators, variance, return and others, allowing the portfolio selection and comparison of different DEA portfolio weighting strategies (Naive 1/N, Markowitz and Sharpe) and SuperDEA. For purposes of analysis, we applied the Data Envelopment Analysis (DEA) method with the input oriented BCC model (BANKER; CHARNES; COOPER, 1984). The results showed a superiority of VRS DEA model in conjunction with the SuperDEA weighting method, as the cumulative weekly continuous returns between January 2011 and December 2014, as the lower values of average monthly volatility. It can be concluded that the adoption of DEA focused on portfolio management, together with the SuperDEA weighting methodology can be considered as effective in the portfolio optimization process in the financial market.

▼ The main reason of this paper is to identify whether macroeconomic variables related to basic interest rate, nominal monthly GDP, exchange rate, stock market and inflation are related to Real Estate profitability which ones have been negotiated on B3. All those REITs were grouped by different sectors look like Banking Agencies, Large Cap Offices, Offices, Funds of Funds, Warehouses, Hospitals, Hotels, Mixed REITs, Receivables, Malls and Retail, Residential and Universities. The analysis was based on time s??ries, having as collected data from January 2011 to December 2017. The results allow a better understanding of the Real Estate Investment Funds grouped by different sectors. Those results are important as soon as we take a look of the profitability variation among the analyzed segments of funds, that fluctuated from 1.95% to 252% regarding the studied period studied as well by the investor's growing investments on those kind of Funds whose daily trading average jumped from R 3,665 million in January from 2011 to R 29,567 million in December 2017. It was observed that the explanatory capacities of the macroeconomic variables worked in this paper, presented heterogeneous results as well heterogeneous influence capacity regarding different Real Estate Investments Funds. As an example, Banking Agencies Funds did not show any significant results to any macroeconomic variables, on the other hand, Shopping Centers Funds, Universities Funds and Hotels Funds were sensitive to the interest rate, nominal monthly GDP and the Ptax Dollar. Considering the current scenario, it should be noted that it would not be possible to generalize the variations of profitability of the Real Estate Investment Funds with the variables analyzed in this paper.

In this work, 60 companies were used, being 30 of them in bankruptcy or insolvency processes in the period from 1994 to 2004, herein referred to as insolvent companies, and 30 of them with normal economic and financial situation referred here as solvent companies. In the present study, 60 companies were used; 30 of them presenting financial restrictions during the year of 2013 and 30 having a normal economic and financial situation. The model proposed by Brito and Assaf Neto (2008) used a logistic regression with 25 economic and financial indicators to see if they were able to separate solvent companies from non-solvent companies. Out of the 25 indicators used for this study, only 4 of them were statistically significant, namely: (I) retained profits on assets, (ii) financial debt, (III) net working capital and (IV) cash balance on sales. This four-variable model obtained a 90% accuracy in the correct classification of solvent and insolvent companies. However, the logistic regression model estimated based on the data from private companies showed different results from the one estimated by Brito and Assaf Neto (2008).In this case, only two variables showed to be statistically significant: (I) equity on assets and (II) cash balance on sales. This adjusted model reached a 57% accuracy in correctly classifying the companies. In short, the results presented here showed that it was not possible to estimate the adjusted credit-scoring model with a good accuracy for privately held companies in Brazil this based on extracted data from their financial statements.

Many IHL consider the distance education, and regionalization strategy that this method enables, a way to maintain or increase their margins. However, the development and operation of these courses require expertise not normally found in traditional classroom structure of institutions. Thus, most managers of IHL find some difficulty in financial planning of the distance education project and its feasibility analysis, this occurs because of the complexity and the amount of variables that impact the definition of income and all expenses, including items from tutors to reviewers, editors, cameramen etc. In this context, this study presents a complete breakdown of the variables that influence the financial outcomes of a distance learning course. The assumptions of the variables are divided into five groups: Organizational Management, Content Development, Information Technology, Mentoring and Market, and its valuation distributed among income, investments and costing.

Measures of the economy such as GDP (Gross Domestic Product), Selic rate, Gross Fixed Capital Formation (FBCF), exchange rate variance and Bovespa Index were associated to IPOs and follow-ons that occurred in the analyzed period summarized quarterly in monetary and quantitative terms. A modest relation between measures of the economy and equity issuance activity was observed, roughly 30%. The Optimism Index (IO) developed by NEFIN and the Consumer Sentiment Index (ICC) calculated by Fecomercio was defined as sentiment measures on the model and they were not statistically significant in the empirical analysis, contradicting studies about investor sentiment relation with the financial market.

To meet the proposed goal it was made a bibliographic research, aiming to identify the relevant elements to valuate a company concerning accounting and financial information. In this sense, it was developed the referred structure. It was conducted a research based on the document analysis technique, attempting to identify in the content of the financial statements of the selected companies the terms presented in the developed performance analysis structure. The research was descriptive and it was applied the qualitative and quantitative approach, to analyze the content of the four companies registered in the BOVESPA MAIS, part of the Clean Energy and Information Technology segments. The proposed goal of this study was reached, as the performance analysis structure was developed based on the literature and, the items of the strucuture had a high level index of presence in the financial statements of the companies analyzed, indicating that is possible to apply such structure in the process of estimating the value of a company.

Ancorada nos pressupostos te?rico-epistemol?gicos e metodol?gicos do C?rculo de Bakhtin e da An?lise Dial?gica do Discurso (ADD), subsidiada nos mesmos pressupostos, tendo como objetivo quais as lacunas e os silenciamentos da Proposta Curricular de L?ngua Portuguesa do Ensino M?dio do Amazonas. Trata-se de uma pesquisa qualitativa, na qual as interpreta??es s?o pautadas na ADD proposta por Bakhtin. Enquanto subs?dio para a an?lise, foram considerados os seguintes documentos oficiais: Par?metros Curriculares Nacionais (PCN, 1998, 1999 e 2000) e Orienta??es Curriculares do Ensino M?dio de L?ngua Portuguesa (OCEM, 2006). Os enunciados oriundos da Proposta apresentam-se em uma estrutura discursiva em que a vontade de mudar e de se materializar existe no ensino de l?ngua, no entanto, o que se evidencia, ainda ? um estudo equivocado na condu??o desse ensino, marcado por um encaminhamento tradicional, que insiste em permanecer por conta da pouca compreens?o acerca de ensino de l?ngua/linguagem que perpassa o contexto educacional.

This research consisted on the analysis of the Portuguese Language High School Curricular Proposal of the state of Amazonas, which was restructured by the State Secretariat of Education and Teaching Quality (SEDUC/AM). The theoretical support that supports this work corresponds to the principles of Applied Linguistics, as fertile field of research regarding Portuguese language teaching. The research was anchored on the theoretical-epistemological and methodological assumptions from Bakhtin Circle and the Dialogical Analysis of the Discourse (ADD), subsidized in the same assumptions, having as objective which gaps and silences from the Portuguese Language High School Curricular Proposal of the state of Amazonas. It is a qualitative research, in which the interpretations are based on the ADD proposed by Bakhtin. As an allowance for the analysis, following official documents are considered: National Curriculum Parameters (PCN, 1998, 1999 e 2000) and Portuguese Language High School Curricular Guidelines (OCEM, 2006). The statements coming from the Proposal are presented in a discursive structure in which the desire to change and materialize exists in language teaching, however, the evidenced, it is that there is still a wrong study in the conduction of this teaching, marked by a traditional approach, which insists on remaining on account of the poor understanding about language teaching that permeates the educational context.

O presente estudo insere-se no âmbito da área curricular de Educação Visual do 3º ciclo do ensino básico, e visa a utilização da obra arquitetónica como recurso educativo para a aquisição de noções de proporção e escala na representação das formas tridimensionais. O tempo de investigação e intervenção teve a duração de dois períodos letivos e foi desenvolvida com uma turma do 8ºano de escolaridade. Ao longo desta investigação, procurou-se averiguar se a perceção da volumetria de uma obra arquitetónica contribuía para o alargamento dos conceitos de proporção e escala e posterior aplicação destes na representação das formas tridimensionais, por parte dos alunos, na realização de maquetes de obras arquitetónicas. Aspira-se que este estudo constitua um contributo para a promoção da relação do aluno enquanto “Homem” com a obra arquitetónica, e que dessa vivencia o individuo enriqueça a sua educação espacial.

Within the scope of Elementary School's 3rd grade Visual Education curricular area, this study focus on the usage of architectural work as an educational resource to grasp the concepts of proportion and representation scale on tridimensional forms. Investigation and intervention lasted for two terms with the direct involvement of an 8th grade class. Throughout this investigation arquitectural scaled models were made by the students to determine if architectural buildings' perception of volumetry helped improving understanding of scale and proportion concepts, as well as subsequent application on tridimensional form's representation. This study aspires to be a contribution to promote the relationship between Student (as a Man) and Architecture, allowing students to improve their understanding of spacial education.

Metodologias para an?lise molecular relacionadas com estudos populacional e forense, t?m sido desenvolvidas a partir de marcadores de microssat?lites (STRs) e as aplica??es desses marcadores, potencialzam os sistemas de amplifica??o por PCR, seja utilizando apenas um par de STRs (monoplex) ou v?rios STRs (multiplex). Para a identifica??o humana por DNA, os primeiros sistemas multiplex foram estabelecidos com STRs de cromossomos autossom?micos, seguidos do uso de STRs de tamanho reduzido, conhecidos como Mini- STRs. Posteriormente, para o cromossomo Y, foram desenvolvidos os Y-STRs, os Mini-YSTRs e mais recentemente o uso dos YSTR de muta??o r?pida (RM)-YSTR. E por n?o existirem dados com STRs do cromossomo Y na popula??o da Cidade de Manaus, o estudo com tais marcadores torna-se relevante. Assim, os objetivos deste trabalho foram desenvolver um sistema multiplex do tipo MiniY-STR para avaliar a efici?ncia na amplifica??o de amostras de casos forenses (DNA degradado) e al?m disso, em conjunto com o Kit comercial PowerPlex?Y23 System (Promega), determinar a frequ?ncia haplot?pica da popula??o da cidade de Manaus. Para tanto, foi constru?do um sistema multiplex ?in house? denominado Mini YSTR09, contendo 9 locos de Mini-YSTR e (RM)-YSTR (Cap?tulo I).Para a valida??o,foram realizados testes de sensibilidade, de detec??o em amostras com misturas e testes em amostras de DNA degradado (98 amostras de osso humano), conforme recomenda??o do SWGDAM. O multiplex foi capaz de amplificar todos os 09 (100%) locos nos sistemas de mistura de DNA e nos sistemas com amostras de DNA degradado (69,4%). Para o estudo populacional (cap?tulo II), as 214 amostras de sangue coletadas de indiv?duos do sexo masculino n?o relacionados geneticamente, foram extra?das com kits comerciais e os produtos amplificados por PCR (31 Y-STRs em tr?s grupos), foram submetidos a eletroforese capilar no sequenciador ABI 3500 e analisados no software Genemapper v. 4,1. 204 amostras foram tipadas com o kit comercial (grupo I), 189 com o Mini YSTR09 (grupo II) e 168 com o conjunto desses dois multiplexs, Kit comercial mais o Mini YSTR09 (grupo III). A presen?a de hapl?tipos ?nicos nos grupos I, II e III foi de 202, 181 e 168, respectivamente. A maior diversidade g?nica foi dos DYS626, DYS570, DYS576 e DYS447, para o grupo I; dos DYS385, DYS570, DYS458, DYS481 e DYS456 para o grupo II e DYS385, DYS461, DYS626, DYS458, DYS576, DYS447 e DYS456 para o grupo III, sendo o DYS447, dentre os mais polim?rficos quando das an?lises no grupo I e III. Portanto, a aplica??o do multiplex Mini YSTR09 aqui desenvolvido, possibiltou a amplifica??o desse DNA em quantidades m?nimas e degradado e al?m disso, para as an?lises populaconais proporcionou uma maior capacidade de discrimina??o quando foi utilizado em conjunto com o kit comercial PowerPlex? Y23 System, destacando-se os locos DYS447, DYS570, DYS576 e DYS626

Methodologies for molecular analysis population and forensic studies, have been developed based on microsatellites or STRs. The…

Neste trabalho apresentaremos o Movimento Browniano do ponto de vista da teoria de Rough Path, abordagem desenvolvida por Terry Lyons na d?cada de 1990. Tal teoria oferece uma alternativa conveniente ao c?lculo estoc?stico de It? no estudo de equa??es diferenciais estoc?sticas. Como pr?-requisitos, construiremos o Movimento Browniano cl?ssico atrav?s do Teorema de Extens?o de Daniell-Kolmogorov e introduziremos os conceitos de integrais de It? e Stratonovitch.

In this paper we will present the Brownian Motion from the point of view of the Rough Path theory, an approach developed by Terry Lyons in the 1990s. This theory offers a convenient alternative to the It? stochastic calculation in the study of stochastic differential equations. As prerequisites, we will build the classic Brownian Movement using the Daniell-Kolmogorov Extension Theorem and introduce the concepts of It? and Stratonovitch integrals.

An?lise de sentimento ? a ?rea de estudo que observa as opini?es das pessoas, sentimentos, avalia??es, atitudes e emo??es em torno de entidades como produtos, servi?os, organiza??es e eventos. No mundo real, empresas e organiza??es frequentemente est?o interessadas em saber opini?es p?blicas sobre seus produtos e servi?os. Os consumidores tamb?m est?o interessados em saber a opini?o de quem adquiriu um produto antes de compr?-lo. Outras pessoas est?o interessadas em saber a opini?o dos outros sobre determinados candidatos de um pleito eleitoral antes de tomar uma decis?o sobre quem ir? votar. O objetivo deste trabalho ? desenvolver um m?todo de aprendizagem supervisionada capaz de classificar tweets em cinco n?veis de polaridade (aprova??o completa, opini?o positiva pontual, opini?o neutra, opini?o negativa pontual e rejei??o completa) usando para isso tweets do contexto pol?tico como estudo de caso. Para tal, investigamos se t?cnicas que fazem detec??o de polaridade de tr?s n?veis s?o capazes de oferecer boas evid?ncias para o treino e testes de classificadores no contexto dos cinco n?veis de polaridade nos tweets. Partindo dessa ideia, propomos estrat?gias de aprendizagem com os classificadores ?rvores de Decis?o, Naive Bayes e SVM usando como features o modelo de bag-of-words, as evid?ncias a partir de resultados de m?todos que classificam polaridade em tr?s n?veis e um modelo de extra??o de meta-informa??o. Os resultados mostraram que existe um ganho nas acur?cias dos classificadores ao combinar os diferentes modelos de features.

Sentiment analysis is the area of study that observes people?s opinions, feelings, assessments, attitudes and emotions around entities such as products, services, organizations and events. In the real world, companies and organizations are often interested in knowing public opinions about their products and services. Consumers are also interested in knowing the opinion of those who bought a product before buying it. Other people are interested in knowing the opinions of others about certain candidates in an election process before making a decision about who will vote. The objective of this work is to develop a supervised learning method capable of classifying tweets in five levels of polarity (complete approval, punctual positive opinion, neutral opinion, punctual negative opinion and complete rejection) using tweets of the political context as a case study. In order to do this, we investigated whether three-level polarity detection techniques are capable of providing good evidence for training and classifier testing in the context of the five polarity levels in tweets. Based on this idea, we propose learning strategies with the Decision Trees, Naive Bayes and SVM classifiers using as features models: bag-of-words, evidence from results of methods that classify polarity in three levels and a meta-level extraction method. The results showed that there is a gain in the accuracy of the classifiers when combining the different models of features.

The closest string problem (CSP) that arises in computational molecular biology and coding theory is to find a string that minimizes the maximum Hamming distance from a given set of strings, the CSP is an NP-hard problem. The main aim of this work is to propose exact methods for this problem, for this purpose, we characterize special cases for this problem with emphasis in the number of strings. Until now our contribution is: linear-time algorithms for CSP with up to three strings and for four binary strings, in addition to an heuristic greedy algorithm and a recursive exact algorithm for CSP for the general case. Furthermore, for each proposed algorithm formal proofs will be presented, also numerical experiments will show the effectiveness of the proposed algorithms.

Este trabalho tem o objetivo investigar o comportamento de complexa??o de metais da Subst?ncias H?micas Aqu?ticas (SHA) frente as varia??es nas propor??es das suas fra??es majorit?rias ?cido H?mico (AH) e ?cido F?lvico (AF), apontando as dificuldades da diferencia??o e maneiras de minimizar essas dificuldades. Para tanto, foram caracterizadas amostras de SHA do rio Negro coletadas em agosto de 2016 e nos meses de mar?o, junho, setembro e dezembro de 2012. As caracteriza??es dos seus componentes qu?micos foram feitas utilizando das t?cnicas de An?lise Elementar, Resson?ncia Magn?tica Nuclear de 13C, Espectroscopia no Infravermelho por Transformada de Fourier, Espectroscopia no Ultravioleta Vis?vel e Espectrometria de Emiss?o At?mica por Plasma Acoplado Indutivamente. Foram feitos estudos de labilidade dos metais Cu, Fe, Al, Mg, Mn e Zn nas diferentes amostras, utilizando o sistema de Ultrafiltra??o de Fluxo Tangencial (UF-TG) e ?ons de Cu2+ como ?on trocador. Foi proposto um novo m?todo de c?lculo da ordem de labilidade dos diferentes metais. A nova proposta de c?lculo foi utilizada nos resultados obtidos pela UF-TG nos estudos com SHA e suas fra??es AH e AF. Utilizando o m?todo proposto, foi poss?vel diferenciar e ordenar a labilidade dos ?ons met?licos presentes nas fra??es AH e AF com a dos ?ons met?licos presentes na SHA. Tamb?m foi estudado a efici?ncia e o impacto da purifica??o por di?lise em processo de batelada na concentra??o de ?ons met?licos orginalmente complexados nos extratos de SHA, AH e AF. Os resultados mostraram que sete bateladas de di?lise s?o necess?rias para reduzir o excesso de ?ons Na provenientes da extra??o da SHA e suas fra??es, e que ?ons de K, originalmente complexados na SHA e em suas fra??es, s?o perdidos durante o processo de di?lise. Esses resultados refor?am a import?ncia da estimativa da perda de ?ons met?licos durante o processo de purificando, evitando assim, afirmativas erronias por exemplo em estudos de troca de ?ons met?licos e de determina??o de constantes de estabilidade. A influ?ncia do car?ter complexante de ?ons met?licos da SHA e sua fra??es tamb?m foi observada em ensaios de toxicidade aguda de ?ons cobre em Art?mia Salina sp. Nesses ensaios, foi verificado que o aumento da fra??o AH na estrutura da SHA tende a melhorar o efeito redutor de toxicidade da mesma.

A crescente utiliza??o de Ambientes Virtuais de Aprendizagem (AVA) como disseminadores do conhecimento auxilia os alunos na constru??o do saber e proporciona uma intera??o entre as pessoas via ferramentas computacionais mediadas pelo professor (mediador ou tutor). Contudo, muitos AVAs n?o possuem um mecanismo ou ferramenta para auxiliar o professor a obter informa??es detalhadas acerca das intera??es sociais dos alunos e dos seus grupos. Isso dificulta a percep??o por parte do professor no que diz respeito ?s rela??es sociais estabelecidas dentro da disciplina. Com base nessas informa??es, o presente trabalho prop?e e detalha uma abordagem para esse problema que faz uso de uma arquitetura de Sistemas Multiagente voltada para a an?lise das intera??es dos grupos. Como prova de conceito, um prot?tipo foi desenvolvido a partir de uma metodologia de software para Sistemas Multiagente, com o objetivo de analisar as intera??es entre os estudantes que ocorreram nos f?runs e nas mensagens de um curso no AVA Moodle e, apresentar essas informa??es ao professor sob a forma de sociograma ou tabela. Desta forma, o professor pode acompanhar visualmente as intera??es de seus alunos dentro do curso e adotar t?ticas que promovam a inser??o social. Para validar o trabalho, foi realizado um estudo de caso como avalia??o de viabilidade, numa turma de um curso de Educa??o a Dist?ncia (EaD) de uma Institui??o de Ensino Superior (IES). De acordo com os resultados obtidos nos testes simulados e com uma turma real, pode-se concluir que a visualiza??o gr?fica das intera??es dos alunos nos f?runs e nas mensagens, quando aliadas ? proatividade dos agentes, pode corroborar o trabalho desempenhado pelos mediadores. A visualiza??o das intera??es proporciona aos docentes uma vis?o mais abrangente, clara e r?pida das rela??es sociais estabelecidas na disciplina, facilitando a op??o de intervir intencionalmente por meio de estrat?gias did?ticas, tais como incentivar os alunos no desenvolvimento da comunica??o, na intera??o e na cria??o de novos grupos.

The increase use of Learning Management Systems (LMS) as disseminators of knowledge aids students in developing knowledge and provides an interaction between people through computational tools mediated by the teacher (mediator or tutor). However, many LMSs does not have a mechanism or tool to aid the teacher to get detailed information about the social interaction between students and their group. This complicates the teacher?s awareness with regard to social relations established within the discipline. Based on this information, this paper proposes and details an approach to this problem that makes use of a Multi-Agent System architecture directed to the analysis of the interactions of groups. As proof of concept, a prototype was developed as using a software methodology for Multi-Agent Systems in order to analyze the interactions between students that occurred in the forums and messages of a course in the LMS Moodle and present this information to the teacher in…

Este trabalho teve como objetivo geral analisar a a??o das oficinas de forma??o da Olimp?ada de L?ngua Portuguesa na voz de docentes de L?ngua Portuguesa e, como espec?ficos, averiguar se as oficinas afetam a concep??o docente em rela??o ao ensino da l?ngua e como, investigar se as oficinas interferem na pr?tica do docente de L?ngua Portuguesa e de que forma e apreender o papel das oficinas de forma??o da OLP para o docente de LP. O referencial te?rico abordou quest?es hist?ricas relacionadas ao ensino da L?ngua Materna na educa??o b?sica fundamentados em Brasil (1998; 2002), Freire (2004), Mendon?a (2014) e Soares (2004), a L?ngua Portuguesa no Ensino M?dio alicer?ados em Antunes (2009), Brasil (2002; 2006; 2008; 2017 [1996]), Mendon?a e Bunzen (2006) e Faraco (2008), a produ??o de textos escritos nas aulas de L?ngua Portuguesa apoiado em Bunzen (2006), Geraldi (1997) e Marquesi (2014). Quanto ? Olimp?ada de L?ngua Portuguesa, foi embasada em Dolz (2011), Dolz, Noverraz e Schneuwly (2004); Marcuschi (2010); Rangel e Garcia (2012) e Set?bal (2008). Ancorada nesses aportes te?ricos, a pesquisa baseou-se no paradigma qualitativo (CRESWEEL, 2007; MICHALISZYN; TOMASINI, 2012; SEVERINO, 2007; STRAUSS; CORBIN, 2008), ? luz de um estudo interpretativista (BORTONI-RICARDO, 2008). Foram utilizados para gera??o a de dados a entrevista e dois question?rios, sendo um de perfil e outro investigativo (LAKATOS; MARCONI, 2002; MONTEIRO, 2009). O contexto de realiza??o da pesquisa foram tr?s escolas de Ensino M?dio do Distrito 6 da zona norte de Manaus. Os resultados indicaram que os professores veem a forma??o continuada como um ?curso t?cnico?, de como dar aula, em outras palavras, um aporte que fornece conte?dos para que seja transmitido futuramente por eles nas aulas. Percebeu-se, tamb?m, a constitui??o de uma concep??o absolutamente antag?nica entre a vis?o tradicional e a atualmente em voga sobre o ensino da l?ngua materna, emergindo na fala de um dos professores um certo orgulho em dizer ?eu sou tradicional?, como se isso desse uma legitimidade ou uma qualidade diferenciada no ensino.

▼ This study compared three ways of the yield to maturity curves behavior analysis in a specific negotiation time period of long term debt titles distributed at one determined period of time. Such mentioned debts are represented by two public issuers from different origins (Brazil and United States), with differentiated tenors in a Yield Time Structure (YTS), for each universe, denominated in a same currency, the United States Dollar. It was searched the definition of which methodology show greater forecasting capacity for the time data series at different time periods of YTS measurement. The time series analyses that indicate the yield behavior of the selected debts will be oriented on the principles of the Pure Expectations Theory (PET), the Liquidity Premium Theory (LPT) and the Univariate Box & Jenkins ARIMA Analysis. It was verified the low applicability of the use of PET and LPT for the YTSs in the two analyzed universes. For the ARIMA use, there is a reasonable acceptance for short term in the YTS of the United States, at the "knot" of measurement of 2 years. For the referring data to the YTS of Brazil, modeling ARIMA showed low forecasting capacity for all "knots" of the analyzed YTSs (2, 3, 4 and 5 years). For the tests of each proposed methodology, historical series of the active yields from the selected bonds had been analyzed, through the use of Excel spread sheets and the Minitab software analysis. The referring data to the historical series of the commented debts yields had been gotten at the Bloomberg L. P. electronic data system, with the previous authorization.

As dificuldades encontradas na resolu??o de problemas de matem?tica, sobretudo, no campo da ?lgebra pode fazer com que os estudantes considerem a Matem?tica e as ci?ncias relacionadas, uma tarefa dif?cil de ser compreendida. Compreender o campo da Matem?tica e as ci?ncias relacionados, ? importante para o desenvolvimento de habilidades cognitivas. Neste contexto, nesta disserta??o foi desenvolvido um Sistema de Tutoria denominado LEIA, cujo objetivo ? promover o aprendizado, identificando as dificuldades nos estudantes e auxiliando na constru??o do pensamento matem?tico. Sendo assim, foi projetado um Sistema de Tutoria composto pela Interface, Modelo do Aluno, Estrat?gias de Tutoria e Modelo de Dom?nio. Al?m disso, um Assistente Virtual Pedag?gico foi inclu?do para auxiliar e motivar os estudantes no processo de aprendizagem. As estrat?gias de tutoria que comp?em o LEIA foram definidas a partir de modelos encontrados na literatura. Para aproximar as intera??es do sistema tutor com as a??es dos professores foi utilizado o Conceito de Zona Desenvolvimento Proximal de Lev Vygotsky. A metodologia utilizada neste projeto foi composta por estudos de caso, aplicados em uma sala de aula. Com os resultados, ficou evidente a aceita??o da proposta pelos estudantes e professores, assim como a percep??o do ganho de aprendizagem a partir da utiliza??o do sistema de tutoria.

The difficulties encountered in solving mathematical problems, especially in the field of algebra, can make students consider mathematics and related sciences a difficult task to understand. Understanding the field of mathematics and related sciences are important for the development of cognitive skills. In this context, this dissertation was developed a Tutoring System called LEIA, which aims to promote learning, identifying difficulties in students and assisting in the construction of mathematical thinking. Thus, a Mentoring System was designed consisting of Interface, Student Model, Mentoring Strategies and Domain Model. In addition, a Pedagogical Virtual Assistant has been included to assist and motivate students in the learning process. The tutoring strategies that make up the LEIA were defined from models found in the literature. To approximate the interactions of the tutor system with the teachers' actions, the Lev Vygotsky Proximal Development Zone Concept was used. The methodology used in this project was composed of case studies, applied in a classroom. With the results, it was evident the acceptance of the proposal by the students and teachers, as well as the perception of learning gain from the use of the tutoring system.

Esta disserta??o teve como finalidade compreender a percep??o da Pr?tica como Componente Curricular (PCC) de professores e alunos no curso de Licenciatura em Ci?ncias Biol?gicas da Universidade Federal do Amazonas (UFAM). Para compreens?o da PCC, analisaram-se documentos oficiais (Resolu??es e Pareceres do Conselho Nacional de Educa??o) e institucionais (Projeto Pedag?gico do Curso de Licenciatura em Ci?ncias Biol?gicas da UFAM) sobre a PCC. Realizaram-se entrevistas com os professores e aplicou-se o question?rio e a t?cnica de grupo focal com os alunos. Para a an?lise dos dados, utilizou-se a An?lise Textual Discursiva (ATD), de Moraes e Galiazzi. Para compreender a percep??o da PCC nos pareceres e resolu??es, recorreu-se a alguns conceitos como teoria-pr?tica, responsabilidade social e pr?tica como componente curricular. Os resultados permitiram compreender que ainda ? incipiente a compreens?o do conceito de PCC na UFAM, e que esta universidade ainda est? distante das discuss?es de outras universidades do pa?s, que j? tiveram mais ajustes depois do Parecer 02/ 2015. Os professores da UFAM percebem a PCC como uma dimens?o pr?tica da teoria, mas existe alguns esfor?os para combater as confus?es de conceito na institui??o. No entanto, a dicotomia entre teoria e pr?tica, a resist?ncia de alguns profissionais, bem como a falta de experiencia de como pode ser feita a PCC, tem representado um entrave na forma??o. Os alunos t?m 3 percep??es da PCC: como momento de aplica??o de ferramentas did?ticas, como momento de constru??o de materiais did?ticos e como momento de inova??o de metodologias de ensino. Conclui-se que a PCC na UFAM, tem potencial para auxiliar na forma??o docente, mas, para isto precisa de alguns ajustes institucionais e profissionais.

This dissertation aimed to understand the perception of Practice as a Component Curriculum (PCC) of teachers and students in the Biological Sciences Degree course from the Federal University of Amazonas (UFAM). To understand the PCC, we analyzed official documents (Resolutions and Opinions of the National Education Council) and institutional (Pedagogical Project of the Degree Course in Biological Sciences of the UFAM) about the CCP. Interviews were conducted with teachers and the questionnaire and focus group technique with students. For data analysis, we used the Discursive Textual Analysis (ATD), by Moraes and Galiazzi. To understand the perception of In the opinions and resolutions, some concepts were used, such as theory-practice, social and practical responsibility as a curricular component. The results allowed understand that the understanding of the concept of CCP at UFAM is still incipient, and that this university is still far from the discussions of other universities in the country, which have already had further adjustments after Opinion 02 / 2015. UFAM professors perceive the PCC as practical dimension of the theory, but there are some efforts to combat the confusion of concept in the institution. However, the dichotomy between…
