In this sense, it sought to discuss and analyze the development of argumentative writing with students from public schools. Although the PCN recommend working with a variety of genres since the late 1990s and the school and the textbooks have inserted various genres in the school the student's daily life, not always genres are worked effectively. This research captures the social and communicative functionality of the opinion article by proposing to carry out a systematic work of teaching and learning of writing in the classroom. Given this perspective, we prepared a didactic sequence, based on Dolz theory, Noverraz and Schneuwly (2004), which proposes a set of activities planned around a genre. The pedagogical action was based on Action Research, because we aim to transform the teaching practice and writing of students. To focus on the language skills needed to write the opinion article, we observed the textual production of students in two periods: the first one through skills to be used during the intervention; the second one, in which we examine the appropriation of genre after the application of didactic sequence. The results revealed that after research, the students began to consider the action skills, with the progress in the use of argumentative type and argumentative justification operations, refutation and negotiation. In addition, the results also indicated a greater concern of students with regard to linguistic and discursive skills, such as using modalizers and argumentative operators. Thus, the study reaffirmed the impact of the application of the didactic sequence in the writing of students. / Esta pesquisa trata da a??o pedag?gica do professor no que diz respeito ao ensino da produ??o de textos escritos no 9? ano Ensino Fundamental. Nesse sentido, buscou-se discutir e analisar o desenvolvimento da escrita argumentativa com alunos da escola p?blica. Apesar de os PCN recomendarem o trabalho com uma diversidade de g?neros textuais desde o final da d?cada de 1990 e de a escola e os manuais did?ticos terem inserido diversos g?neros no cotidiano escolar do aluno, nem sempre os g?neros s?o trabalhados de modo efetivo. A presente pesquisa resgata a funcionalidade social e comunicativa do g?nero artigo de opini?o, ao propor a realiza??o de um trabalho sistem?tico de ensino-aprendizagem da escrita do g?nero em sala de aula. Diante dessa perspectiva, elaboramos uma sequ?ncia did?tica, fundamentada na teoria de Dolz, Noverraz e Schneuwly (2004), a qual prop?e um conjunto de atividades planejadas em torno de um g?nero textual. A a??o pedag?gica apoiou-se nos pressupostos da pesquisa-a??o, dado que objetivamos transformar a pr?tica docente e a escrita dos alunos. Tendo como ponto central as capacidades de linguagem necess?rias ? escrita do artigo de opini?o, verificou-se a produ??o textual dos alunos em dois momentos: o primeiro de car?ter investigativo, mediante avalia??o das capacidades a serem abordadas durante a interven??o; o segundo de car?ter avaliativo, em que se verificou a apropria??o do g?nero ap?s a sequ?ncia did?tica. Os resultados revelaram que, ap?s a realiza??o da pesquisa, os alunos passaram a considerar o contexto de produ??o do g?nero, havendo progressos quanto ao uso da tipologia argumentativa e das opera??es argumentativas de justifica??o, refuta??o e negocia??o. Al?m disso, ainda que os alunos n?o tenham se apropriado plenamente da escrita do g?nero, os resultados indicaram tamb?m uma maior preocupa??o dos alunos com rela??o ?s capacidades lingu?stico-discursivas, como o uso de modalizadores e de operadores argumentativos. Sendo assim, o estudo reafirmou o impacto da aplica??o da sequ?ncia did?tica na escrita dos alunos.

This paper is dedicated to the empirical analysis of the pilot trainee project Stáže ve firmách, which is considered as treatment in this analysis. The main objective of the empirical analysis is estimation of average treatment effect(ATE) and average treatment effect on treated(ATET) for characteristics like socioeconomic status and wage. Counterfactual methods for policy impact evaluation like Difference in Differences Estimator(DiD), First Differences Estimator(FD) and Propensity Score Matching(PSM) are used to estimation mentioned effects. This paper contains extension of Assignment Problem that is used for people matching purposes as alternative for PSM. This way of matching provides better control over creation of couples. Resulting pairs are more similar in selected characteristics due to better control during couples creation process.

Gegenstand dieser Diplomarbeit ist die Untersuchung der Dynamik in dünnen Polymerfilmen anhand von einzelnen Molekülen. Zu diesem Zweck wurden dünne Filme (kleiner 100nm) hergestellt und mittels Einzelmoleküldetektion und zeitaufgelöster Einzelphotonenzählung analysiert, was eine orts- und zeitaufgelöste Untersuchung einzelner Farbstoffmoleküle ermöglicht. Ziel war es, festzustellen ob, und auf welchem Weg, die Dynamik der Umgebung in Fluktuationen der Fluoreszenzlebensdauer einzelner Moleküle sichtbar wird. Neben der Evaluierung der Untersuchungsmethoden wurden in dieser Arbeit zwei Arten von Sensormolekülen - DiD und Malachit Grün - näher untersucht. / The subject of this diploma thesis is the analysis of dynamics in thin polymer films using single molecules. Thin polymer films (less than 100nm) were produced and analysed by Single Molecule Detection (SMD) and Time Correlated Single Photon Counting (TCSPC). This allows a spatial and time resolved investigation of the single dye molecule. The aim was to ascertain if, and in which way, the dynamics of the environment are reflected by fluctuations of the fluorescence lifetime of the single molecule. In addition to evaluating the investigation methods two kinds of molecules - DiD and Malachite Green - were also analysed.

Alcohol, recently named the most dangerous drug in the world, contributes to nearly 40% of violent crimes and fatal traffic accidents, increases risk of roughly 60 different diseases and injuries, and is responsible for 2.5 million deaths each year worldwide. Despite these staggering figures, treatments remain ineffective and riddled with adverse side effects, making successful use of even the most effective treatments unlikely. Moreover, many of the treatments, and the supporting research, have focused only on male subjects, despite sex differences in various alcohol-related behaviors. Human alcohol use is frequently accompanied by nicotine use, and vice versa, suggesting a common mechanism of the two drugs. In fact, alcohol may act through the same family of receptors as nicotine, the nicotinic acetylcholine receptors (nAChRs), eliciting similar activation of the reward pathway as nicotine and other drugs of abuse. Studies have shown that nAChRs containing the α4 and/or α6 subunits are involved in nicotine-induced activation of the reward pathway, leading to the hypothesis that these same receptor subtypes may be important for alcohol effects in the brain as well. Using male and female genetic mouse models and various behavioral assays, we have shown not only that these α4 and/or α6-containing nAChRs are involved in alcohol- related behaviors and activation of the reward pathway, but also show sex differences in this involvement. Uncovering the mechanism of alcohol in the brain, in males as well as in females, is an important step in developing targeted treatments for alcohol abuse.

This thesis investigates if the announcement of lockdown had a significant impact on stock market return in Denmark. The research approach used is quantitative and deductive and the sample consists of ​​daily adjusted close prices of stock from the 20 largest listed companies in Denmark, according to market capitalization rate. The time period studied is 28th of February 2020 till 27th of March 2020. Lockdown's effect on stock market return is studied using a Difference-in-Difference model, where daily adjusted close prices of stocks from the 20 largest companies in Sweden are used as a control group.  The COVID-19 pandemic has for the past two years had a huge impact on societies globally. At the beginning of the COVID-19 outbreak, to try and stop the spread of the virus, governments around the world implemented lockdowns of varying degrees. Denmark was one of the first countries to implement lockdown. However, the culturally and market similar Sweden, opted for a different approach and did not implement a lockdown at all. It is therefore of interest to investigate whether lockdown announcements had a measurable impact on stock returns at the beginning of the COVID-19 outbreak. Previous research conducted by Vasileiou (2020), Baker (2020), Ichev and Marnič (2018), Hassing Nielsen & Lindvall (2021) and Ashraf (2020) on the subject have found that COVID-19 generally contributed to market uncertainty. This uncertainty in turn affected the stock market significantly, both positively and negatively. The major findings of this thesis suggest that the lockdown implemented in Denmark had no significant effect on stock returns during the investigated sample period.

At the same time, it is important that this teacher organizes his practice from didactical and pedagogical guidelines of teaching through textual genres, which crosses the bias of the didactical sequences of Bernard Scheneuwly and Joaquim Dolz as well as the theoretical interactionist idea of Levy Vygotsky. It is also necessary trying to understand approaches that comprise the multimodal universe of various emerging communication forms, which consolidates several sign systems that interweaves each other in order to establish language uses, and thus the result of human relations expressed by ways of several languages. This implies to mention literacy and multi-literacy, once multimodality is a constitutive characteristic of social communicative forms, which are found in society in accordance with technological development. Not only this emphasizes oral and written interactions, but also includes every communicative technology. Once that new means of organization for academic knowledge are created as a result of this context of continuous changes and that new means of reading, interpreting and producing texts are constantly being produced, this paper presents only those ones focused on the study of languages, which stimulates a didactic and pedagogical transposition flexible to several cultural contexts. From this assumption, this paper aims to present results from a research conducted on the program of post-degree in Agricultural Education (UFRRJ), which intends to create a summary and analyze critically the knowledge and didactical and pedagogical practice of Portuguese Language Teachers of The Federal Institute of Amap?. Thus, this study purposed to see that the Portuguese-speaking school with a didactic and pedagogical practice rooted in the theory of genres , guided at first by the National Curriculum Standards , can help pluridiscursivo language learning , going beyond what is proposed and waiting for this document , achieving citizenship education linked to the context of technological change , in which different genres emerge as the sociocomunicativa needs of individuals in situations of social interaction / O ensino de L?ngua Portuguesa ministrado pelo professor da contemporaneidade n?o pode prescindir das orienta??es e influ?ncias dos Par?metros Curriculares Nacionais e dos postulados te?ricos da Lingu?stica Textual, os quais s?o ancorados nos princ?pios te?ricos de Mikhail Bakhtin. Ao mesmo tempo, ? importante que esse profissional organize sua pr?tica, a partir de orienta??es did?tico-pedag?gicas de ensino com g?neros textuais, as quais perpassam pelo vi?s das sequ?ncias did?ticas de Bernard Schneuwly e Joaquim Dolz, bem como pela vertente te?rica interacionista de Levi Vygotsky. ? necess?rio, tamb?m, buscar compreender abordagens que abranjam o universo multimodal das distintas formas comunicativas emergentes, em que se consolidam diversos sistemas de signos. Isso implica referirmo-nos ao conceito de Letramento(s) e/ou de Multiletramentos, uma vez que a multimodalidade ? um tra?o constitutivo das distintas formas sociocomunicativas que circulam em sociedade, em fun??o do desenvolvimento tecnol?gico. Por conseguinte, sabe-se que, nesse contexto de transforma??es constantes, surgem novos meios de estrutura??o dos conhecimentos cient?ficos; destacando, aqui, apenas aqueles voltados para ?rea de linguagens, os quais suscitam uma transposi??o did?tico-pedag?gica flex?vel aos contextos culturais diversificados, tendo em vista que, a todo instante, s?o instauradas novas maneiras de ler, interpretar e produzir textos. A partir desses pressupostos, este trabalho tem como objetivo principal apresentar resultados de uma pesquisa realizada no ?mbito do Programa de P?s- Gradua??o em Educa??o Agr?cola da (UFRRJ), em uma institui??o Federal de Educa??o, Ci?ncia e Tecnologia do estado do Amap?. Dessa maneira, esse estudo intencionou constatar que o ensino de l?ngua portuguesa com uma pr?tica did?tico-pedag?gico alicer?ada na teoria dos g?neros textuais, orientada, a princ?pio, pelos Par?metros Curriculares Nacionais, pode favorecer o aprendizado pluridiscursivo da l?ngua, indo al?m do que ? proposto e esperado por esse documento, alcan?ando uma forma??o cidad? vinculada ao contexto das transforma??es tecnol?gicas, em que distintos g?neros emergem, conforme a necessidade sociocomunicativa dos indiv?duos nas situa??es de intera??o social

Technology nowadays is evolving at rates that surpass anything imagination could perceive and it certainly affects every public or private enterprise. Well, according to this topic, I’m suggesting the improvement of the communications network of the Regional Government of Lima based on an integrated data and voice platform which includes a Cisco Centralized IP Telephony solution, called Cisco Unified Communications Manager 7.0, that works as a main element in order to achieve meaningful and complete management of internal and external telephone calls within MPLS Networks. Regional Government of Lima has been chosen because of its importance related to the economic activities of the population and the support that could be brought by an institution which could make success and generate productivity about rapid administrative processes . The thesis is divided into distinct chapters that make up the context of the investigation which involves network planning and design as an iterative process, encompassing topological design, network realization, IT asset sourcing and operations planning. For this purpose, information about the old and non sophisticated network status was raised. Costs and more details such as hardware and software features and more ways to make this network work so much better, with all the resources at its disposal, will be found on this whole solution

The authors of this text were four teachers who have been teaching or taught the subject of history at the Indigendus School of Patax? Coroa Vermelha ? Red Crown located in the country of Santa Cruz de Cabr?lia in the south of Bahia. Having the accomplishment of this investigation done in this aforementioned school was necessary to obtain the altogether authorization as the followed: from the chief of the village Coroa Vermelha Red Crown, from the direction of the body of teachers who was investigated, from National Foundation of Indian (FUNAI) as well as the Committee of Ethics and Research Involved with Humanbeings (CEP), from the University of the State of Feira de Santana (UEFS). This piece of research is about the representation of the Indians cantained in the didactic book of History also contemplating the specifications of the book of the grade school witch was adapted by the school among others indicated by the government. Besides, the analysis of texts and the images presented in one of the chapters mentioned in the book which particularly deals with the indigenous peoples. This piece of reseach was of qualitative nature and having the interview semistructered as the main instruments of collecting the data, furthermore the verbal texts and imagery presented in the didactic book. The data were analyzed from the theoreticalmethodological perspective of the analysis of the images it was verified that although the chapter of the book analyzed and used by the teachers in their work the material brings along some advancements in relation to the thematic of the book contains images and verbal texts with stereotyped representations about the Indians. We could find the indigenous teachers put together in a critical way the representations and verbal speeches and imagery contained in the didactic book among many factors in themselves. We quote: the preservation of their traditions costums and cultural in heritance, the use of specific didactic materials from their culture and the technological Resources available in the school due to continued academic background as well as the knowledge of specific legislation aiming at education of the Indians among others. The indian peoples acquire each day more knowledge about their rights and personalized education and education also surpasses the planning of specific and didactic books whest quality fits the maximum of the culture of the indigenous peoples. This piece of research contributes to rethink the distortions that are still present in the didactic book of history related to the images and verbal texts about the Indians considered in its most important aspects the discursive perspective of the indigenous teachers in the context of the school of Patax?. This points out the necessity of re evaluating the didactic books produced with the participation or even the striking direction of the Indians taking into account the view of the diversity of specificity and the rich variety of the culture of indigenous peoples of patax?. / Esta disserta??o tem como objeto de estudo o ?ndio no livro did?tico de hist?ria e a (des)constru??o de representa??es pelo professor ind?gena patax?. A an?lise transitou entre os textos verbais e imag?ticos do cap?tulo espec?fico do livro did?tico de hist?ria que trata da tem?tica ind?gena e o discurso de quatro professores patax? que lecionam ou lecionaram a disciplina Hist?ria na escola ind?gena Patax? Coroa Vermelha, localizada no munic?pio de Santa Cruz Cabr?lia, no extremo sul da Bahia. Para a realiza??o desta investiga??o na referida escola, foi necess?rio obter um conjunto de autoriza??es, a saber: do Cacique da aldeia Coroa Vermelha, da dire??o, do corpo docente a ser investigado, da Funda??o Nacional do ?ndio (FUNAI), bem como do Comit? de ?tica em Pesquisa Envolvendo Seres Humanos (CEP), da Universidade Estadual de Feira de Santana (UEFS). A pesquisa foi de natureza qualitativa, tendo a entrevista semiestruturada como instrumento principal para a coleta dos dados, al?m dos textos verbais e imag?ticos presentes no livro did?tico. Os dados foram analisados a partir da perspectiva te?rico-metodol?gica da An?lise de Discurso de Linha Francesa e da An?lise da Imagem. Verificou-se que embora o cap?tulo analisado do livro trabalhado pelos professores traga alguns avan?os em rela??o ? tem?tica ind?gena, de forma geral, ainda cont?m, nas imagens e textos verbais, representa??es estereotipadas sobre os ?ndios. Podemos constatar que os professores ind?genas desconstroem, de forma cr?tica, as representa??es e discursos verbais e imag?ticos contidos no livro did?tico, por conta de v?rios fatores, dentre eles: a preserva??o de suas tradi??es; costumes e riqueza cultural; o uso de materiais did?ticos espec?ficos de sua cultura e dos recursos tecnol?gicos dispon?veis na escola; devido ? forma??o acad?mica continuada, bem como o conhecimento da legisla??o espec?fica para educa??o ind?gena. Os povos ind?genas adquirem, cada vez mais, conhecimento a respeito dos seus direitos sobre a educa??o diferenciada e esta educa??o perpassa tamb?m pela constru??o de livros did?ticos espec?ficos e de qualidade que se adequem, ao m?ximo, ?s culturas dos povos ind?genas. A pesquisa contribui para repensar as distor??es ainda presentes no livro did?tico de Hist?ria no que se refere ? imagens e textos verbais sobre os ?ndios, considerando, de forma primordial, a perspectiva discursiva de professores ind?genas no contexto da escola Patax?. Isto sinaliza a necessidade de que os livros did?ticos sejam reavaliados e produzidos com a participa??o ou mesmo a dire??o contundente dos ?ndios, tendo em vista contemplar a diversidade, riqueza e especificidades das culturas ind?genas.
