Karl Marx developed the theory of historical materialism which maintains a history of society determined by class struggle and the! exploitation of man by man. Considered to be overtaken by those who believe that Marxism is synonymous with real socialism, the Marxist ideals seem more present than in the Western world which each individual takes the individualization (loss of sense of public and collective) and the alienation by the work. Weassumed we could work on these issues in student education, even in elementary school, through questioning of the consumer society, with the criticism of television and the media, the main promoter of the current sense of consumption, as an initial step that could lead to future autonomy of theindividual. The theory of ideology and ideas of Paulo Freire's liberating education theory permeated the experience that happened as a participant observation of groups in the discipline of sociology in the unit 2 of the Col?gio Pedro II in Rio de Janeiro, the state capital, an institution under the direct administration Ministry of Education. Wehave found fertile ground in which the students were able to understand and question the meaning of advertising media / O consumo se tornou um dos principais pilares do capitalismo moderno e, ao mesmo tempo, um dos fatores que se relacionam ? desigualdade social. Karl Marx desenvolveu a tese do materialismo hist?rico que defende uma hist?ria da sociedade determinada pela luta de classes e pela ‟explora??o do homem pelo homem . Considerado ultrapassado por aqueles que acreditam que marxismo ? sin?nimo de socialismo real, as ideais marxistas nos parecem mais do que atuais num mundo ocidental que leva cada indiv?duo ? individualiza??o (perda da no??o de p?blico e coletivo) e ? aliena??o pelo trabalho. A teoriza??o de Luk?cs sobre as teorias marxistas refor?a esta ideia, quando diz que este processo engloba todo o sistema social. Partimos do pressuposto que poder?amos trabalhar estes temas na forma??o do aluno, ainda no Ensino Fundamental, atrav?s do questionamento da sociedade de consumo, com a cr?tica ? televis?o e ? m?dia, principal promotora do atual sentido de consumo, como passo inicial que poderia levar ? futura autonomia do indiv?duo. A teoria da ideologia e as ideias de educa??o libertadora de Paulo Freire permearam teoricamente a experi?ncia que aconteceu como observa??o participativa numa das turmas da disciplina de Sociologia numa das unidades do Col?gio Pedro II, no Rio de Janeiro, capital do estado, institui??o sob administra??o direta do Minist?rio da Educa??o. Encontramos um terreno f?rtil em que os alunos se mostraram aptos a entender e a questionar o sentido da publicidade midi?tica

In this goal, the study seeks to drive a multiplicity of angles and methods to illuminate specific aspects of the case study, as well as areas that intersect in the production of meaning. The Job Reporter is built, as well as the appropriate object to analyze the theories of self-referentiality and the strength of the media contract, given the overlap in the derived logical not factual genres and related entertainment that format or feed back what is established in the course of time, as the "real" features of this regional space.

O enfoque no figurino ? realizado a partir da Semiologia e objetiva decifrar os sentidos produzidos na indument?ria. Tr?s personagens dos filmes ter?o os seus figurinos analisados a partir da teoria de Roland Barthes, principalmente com os elementos da Semiologia (l?ngua e fala), (significante e significado) e (sistema e sintagma). A influ?ncia do movimento Armorial no filme O Auto da Compadecida e da est?tica Kitsch no filme O Bem Amado merecem uma reflex?o, al?m do estudo da fun??o do figurino no interior da narrativa amparado pela an?lise estrutural da narrativa de Roland Barthes. Buscamos identificar o equil?brio entre a fala dos personagens e a imagem da indument?ria f?lmica. Para complementar o estudo do poder do figurino na narrativa, estudamos os tra?os caracter?sticos do diretor e roteirista Guel Arraes nas suas obras, que s?o a identidade de nordestino, a representa??o do Nordeste e a com?dia popular. Partimos do princ?pio que o trabalho de escolhas de sua cria??o n?o est? separado das influ?ncias que o diretor teve durante sua vida. A nossa pesquisa se concentrou na aprecia??o dos filmes e na investiga??o minuciosa de toda a linguagem. As principais reflex?es t?m como sustenta??o as seguintes teorias: Barthes (2007), Figueir?a e Fechine (2008), Moles (2001), Stuart Hall (2005) e Mikhail Bakhtin (2013). / This research focuses on the course of Guel Arraes, moviemaker, and picks two movies for analysis: O Auto da Compadecida (2000) and O Bem Amado (2010), as well as their costumes. The focus on the costume is based on Semiology and aims to decode the meanings that stem out of the clothes. Three of the movies characters will have their costumes analyzed based on Roland Barthes? theory, mainly considering semiology elements (language and speech), (significant and meaning) and (system and syntagma). The influence of the Armorial movement into the movie O Auto da Compadecida and the Kitsch aesthetic in O Bem Amado deserve consideration, aside from the study on costumes function within narrative, supported by Roland Barthes? structural analysis of the narrative. We sought to highlight the balance between characters? lines and the image of the costumes in the movies. Adding to the study on how costumes strongly accounts to narrative, we observed characteristic traits of director and scriptwriter Guel Arraes present in his works, which are the northeastern man identity, a presentation of the Northeast and popular comedy. We believe that his choices when creating and his life influences are not separate from one another. Our research was movie-appraisal centered and had a thorough investigation all over language. The main considerations are supported by the following theories: Barthes (2007), Figueir?a and Fechine (2008), Moles (2001), Stuart Hall (2005) and Mikhail Bakhtin (2013).

Searching is thus a conceptual framework that takes into account the kind of ideology that naturalizes the relationship of leisure with the foundations of contemporary media, and the media only with leisure, forgetting their insertion in the labor and industrial relations in society. We intend to demonstrate that every mode of production, in the capitalist system, entails a mode of reproduction. Methodologically, this is a first approximation, from theoretical concerns already performed, constituting a theoretical research, bibliographic and descriptive character. The results of the text drives us to the conclusion that the work and leisure spheres tend to be less and less differentiated, since both remain as activities of product management with the same intellective protocols, based on information and communication technology, and that accordingly, the media favors an expansion of productive activity even during leisure time / A presente pesquisa se prop?e a compreender as rela??es entre m?dia, capitalismo e apropria??o do tempo livre pelas pr?ticas de lazer nas sociedades industrial e p?s-industrial. Busca-se, assim, um aparato conceitual que d? conta da esp?cie de ideologia que naturaliza a rela??o do lazer contempor?neo com os fundamentos da m?dia, e da m?dia apenas com o lazer, olvidando sua inser??o no mundo do trabalho e das rela??es em sociedade. Nossa inten??o ? tamb?m tangenciar a ideia de que todo modo de produ??o encerra um modo de reprodu??o de seus enunciados constituintes, a despeito de n?o se ver a possibilidade de se descrever um modo de produ??o puro, com origem determinada, apenas ?ndices de esquemas predominantes. Metodologicamente, trata-se de uma primeira aproxima??o, a partir de apreens?es te?ricas j? realizadas, constituindo-se de uma pesquisa te?rica, bibliogr?fica e de car?ter descritivo. As sistematiza??es articuladas apontam para a confirma??o de que a esfera do trabalho e a esfera do lazer tendem a estar cada vez menos diferenciadas, uma vez que ambas mant?m como atividades centrais o manejo de produtos com protocolos intelectivos comuns (tecnologia da informa??o e da comunica??o) e que, nesse sentido, a m?dia favorece a uma amplia??o da atividade produtiva mesmo nos momentos de lazer

This is, thus, pushed to say what he saw, heard or touched. In this paper, we verified the effects of senses produced in the blog of Bishop Macedo, founder of the Universal Church of the Kingdom of God (UCKG), from a corpus which consists of nine testimonies of presumed believersselected among 64 statements distributed during the year, 2012. Instead of instantaneous testimonials, on a live presentation, these media narratives are underpinned by attributes such as hyperlinks, visuals, language translators, besides mechanisms of interaction and sharing in other spheres from mediatic slant. The problem of this analysis was born from the observation of regular points in the discursive architecture of these testimonials, when was identified the existing relation force between the sacred and the profane, everyday practices. During six months, analysis of the empirical material, we found some effects of the senses on the testimonials, as the dialectic structure and the need for denuding a precarious past, an engagement to shield the figure of Macedo and the UCKG towards society; a update of a crusade against other religions; and the presence of certain sensuality in self-deprecation of the deponents, and an unequal relation of forces (sacred and profane) in the construction of truth. In order of succeeding in this investigation, we used the theoretical and methodological assumptions of Analysis of French Discourse (AD), denouncing the qualitative nature of the research. As a methodological principle, we still use transdisciplinarity, which validated some of our dialogues, especially with philosophy. The conception of discourse modeled by a media support and transpassed by the subject(s) and story (ies) characterized the perspective of the research / O testemunho ? uma maneira de enuncia??o que demonstra ou admite a exist?ncia de uma realidade com a qual o enunciador entrou em contato. Esse ?, pois, levado a dizer o que viu, ouviu ou tocou. Neste trabalho, buscamos verificar os efeitos de sentido produzidos no blog do Bispo Edir Macedo, fundador da Igreja Universal do Reino de Deus (IURD), a partir de um corpus que re?ne nove testemunhos de supostos fi?is, selecionados entre 64 depoimentos distribu?dos durante o ano de 2012. Diferente dos depoimentos instant?neos, de uma apresenta??o ao vivo, essas narrativas midi?ticas s?o alicer?adas por atributos como hiperlinks, elementos visuais, tradutores lingu?sticos, al?m dos mecanismos de intera??o e compartilhamento em outras esferas tamb?m de cunho midi?tico. A problem?tica desta an?lise nasceu a partir da observa??o de pontos regulares na arquitetura discursiva desses testemunhos, quando foi identificada a rela??o de for?as existentes entre o sagrado e o profano e as pr?ticas cotidianas. Durante seis meses, tempo de an?lise do material emp?rico, encontramos alguns efeitos de sentido nos testemunhos, como: a estrutura dial?tica e a necessidade de desnudamento de um passado prec?rio; um engajamento para isentar de culpa a figura de Edir Macedo e da IURD perante a sociedade; a atualiza??o de uma cruzada contra outras religi?es; a presen?a de certa sensualidade na autodeprecia??o dos depoentes; e uma rela??o desigual de for?as (sagrado e profano) na constru??o da verdade. Para dar conta desta investiga??o, utilizamos os pressupostos te?ricos e metodol?gicos da An?lise do Discurso de linha francesa (AD), denunciando a natureza qualitativa da pesquisa. Como princ?pio metodol?gico, fizemos uso ainda da transdisciplinaridade, que legitimou alguns dos nossos di?logos, sobretudo com a filosofia. A concep??o de discurso modelada por um suporte midi?tico e atravessado pelo agenciamento de sujeito (s) e pela (s) hist?ria (s) caracterizou a perspectiva da investiga??o

Linguagem (Adieu Au Langage, 2014), no que toca a rela??o entre cinema e pintura. Duas quest?es centrais nortearam o foco desta investiga??o: como se d? a constru??o simb?lica da maneira pict?rica de Godard? Os elementos pict?ricos presentes na narrativa f?lmica se prop?em realmente a construir significados e transmitir sensa??es reais como as do movimento impressionista nas pinturas? A rela??o entre cinema e pintura na obra de Godard ? trabalhada aqui no contexto de promover um di?logo entre as artes e a comunica??o. Partindo do pressuposto de que filmes s?o objetos art?sticos que comunicam por meio de elementos simb?licos, este trabalho busca identificar a forma simb?lica de Godard dentro de uma linguagem h?brida por meio da an?lise de elementos como a cor e a luz. / This research aimed to expand the existing studies regarding the relationship between cinema and painting, investigating how the symbolic form acting in the hybridism present in the films of French film director Jean-Luc Godard. The dissertation is developed in two chapters. The first chapter, entitled "From pictorial to cinematographic", focuses on cinema and its transformations concerning the ways to represent the "real", emphasizing the French New Wave and Godard?s cinema. In the second chapter, entitled ?Cinema, painting and hybrid language in Jean-Luc Godard?, after defining the concept of hybridism and its applicability, regarding the use of color, to the aspects of symbolic, hybrid and intertextual representation in the cinema, the films Pierrot Le Fou (1965), Passion (1982) e Goodbye to Language (2014) are analyzed in light of Vanoye and Goliot-L?t? (1994), Penafria (2009) and Rose (2003). Throughout the text, the relationship between cinema and painting in Godard's work is carried out with a view to promoting a dialogue between art and communication. Two questions guided the investigation: how does the symbolic construction of Godard's pictorial way take place? Do the pictorial elements present in the filmic narrative really propose to construct meanings and transmit real sensations like those of the Impressionist movement in the paintings? In the understanding achieved by the research, it is affirmed that symbolism and poetics are inherent in cinema and painting in the film production of Jean-Luc Godard.

Atualmente percebe-se o crescimento do n?mero de document?rios que tem como mat?ria prima a hist?ria narrada em primeira pessoa, que se afasta da narra??o distante e imparcial dos document?rios tradicionais, dando abertura a um olhar mais subjetivo e aproximado sobre a hist?ria. No presente trabalho realizamos um estudo de caso sobre Utopia e Barb?rie buscando entender os aspectos subjetivos e ?ntimos do diretor envolvidos na narrativa. Assim tomamos como objetivo a identifica??o dos procedimentos est?ticos utilizados nessa narrativa e como neles se manifestam a afetividade e as mem?rias de seu realizador. Para tanto utilizamos como referencial te?rico o conceito de ?espa?o biogr?fico? de Leonor Arfuch (2002), mem?ria coletiva de Maurice Halbwachs (1950) e o conceito de sujeito fragmentado Stuart Hall (1996) para nortear nossa an?lise. Utopia e Barb?rie, um filme-ensaio narrado em primeira pessoa que promove uma mistura de elementos visuais e sonoros para produzir um documento hist?rico, n?o o bastante faz isso pelo vi?s pessoal do seu realizador, que ? o condutor da hist?ria e atrav?s dela revela detalhes de sua vida pessoal fazendo uso de fotografias pessoais, filmes e pela voz over que o representa. / The film Utopia e Barb?rie (2010) tells the story of the famous generation that marked the second half of the twentieth century called the generation of 1968, by the look of its director Silvio Tendler. Nowadays, it is possible to notice the growth in the number of documentaries that have as story material the story told in the first person. Here we ask ourselves the aesthetic procedures used for this narrative and how it manifests the affectivity and the memories of its filmmakers. In the present work we carried out a case study about the film seeking to understand the subjective and intimate aspects of the director involved in the narrative. For that, we use as theoretical reference the concept of "biographical space" of Leonor Arfuch (2002), collective memory of Maurice Halbwachs (1950) and the concept of fragmented subject Stuart Hall (1996) to guide our analysis. Utopia e Barb?rie, a first person essay film promotes a mixture of visual and sound elements to produce a documentary history, not enough does it for the personal bias of its director, who is the conductor of the story and through it reveals details of his life Personal making use of personal photographs, films and the voice over that represents him.

Processos cognitivos b?sicos regulam o desempenho dos indiv?duos. Nesse trabalho, avaliamos a aten??o, a mem?ria operacional e a flexibilidade cognitiva. Esses processos podem sofrer influ?ncia da irregularidade e da priva??o de sono, acarretando redu??o na performance cognitiva podendo prejudicar a aprendizagem. Nesse trabalho, verificamos se os h?bitos de sono, a sonol?ncia diurna e a cogni??o de adolescentes do turno matutino variam em fun??o do uso de m?dia. Assim, 83 estudantes (60 meninas, 23 meninos) da segunda s?rie do ensino m?dio de escolas privadas de Natal/RN responderam question?rios (A sa?de e o sono, Avalia??o do Cronotipo de Horne-?stberg e Escala de Sonol?ncia de Epworth) e uma bateria de testes cognitivos (avalia??o da aten??o por uma Tarefa de Execu??o Cont?nua; mem?ria operacional, pelo Subteste de d?gitos; e Flexibilidade cognitiva pelo teste de trilhas e de Berg de classifica??o de cartas). Al?m disso, preencheram o di?rio do sono durante 10 dias (incluindo a pergunta ?o que estava fazendo antes de dormir??) e um protocolo di?rio de uso de m?dia por dois dias na semana e dois no final de semana. No geral, o uso de m?dia foi maior no fim de semana em rela??o ? semana, e o dispositivo mais utilizado foi o celular, seguido de televis?o e computador. N?o foram encontradas correla??es entre a estimativa de uso semanal de m?dia e os par?metros relacionados ao sono. Contudo, foram encontradas correla??es fracas entre a estimativa semanal de uso e: a estabilidade geral na aten??o (r=-0,23; p<0,05), os pontos (r=0,22; p<0,05) e escore total (r=0,22; p<0,05) na ordem direta do subteste de d?gitos, e os erros ?nicos (r=-0,26; p<0,01) do teste de Berg. Em rela??o ? frequ?ncia de uso de m?dia antes de dormir, a televis?o aparece como o dispositivo preferido pelo grupo que mais usa m?dia neste hor?rio (G3). De forma geral, os hor?rios de deitar e levantar diferiram entre os dias de semana e fim de semana, mas n?o houve diferen?a na irregularidade nos hor?rios de deitar e levantar em fun??o do uso de m?dia antes de dormir. Foram encontradas diferen?as nos hor?rios de levantar no fim de semana, de modo que o grupo com menor frequ?ncia de uso de m?dia antes de dormir (G1) levantou mais cedo (Anova, p<0,01 -Bonferroni, p<0,05). A maioria dos estudantes apresentou sonol?ncia diurna excessiva, com diferen?as nas propor??es entre os grupos. Por?m, os maiores percentuais foram observados sucessivamente no G1 e G3 (X2, p<0,05). Quanto ao desempenho nos testes cognitivos, o G1 apresentou menor percentual de omiss?es no alerta f?sico (Mann-Whitney, p<0,05), uma tend?ncia a um menor percentual de omiss?es em rela??o ? aten??o sustentada (Kruskal-Wallis, p=0,06), maior n?mero de pontos na vers?o indireta do subteste de d?gitos (Mann-Whitney, p<0,05) e uma tend?ncia a ser mais eficiente na vers?o A do teste de Trilhas (Mann-Whitney, p<0,05). De maneira geral, esses resultados corroboram nossas hip?teses de que o uso de m?dia influencia o sono, a sonol?ncia diurna e a performance cognitiva, principalmente quando a utiliza??o dos dispositivos eletr?nicos ocorre pr?ximo ao hor?rio de deitar. Por?m, estudos adicionais com um maior n?mero de indiv?duos s?o necess?rios para confirmar estas evid?ncias. / The phase delay with respect to schedules of bedtime and wake up time in adolescence added to the growing media use can cause exposure to light at inappropriate times, irregularity of sleep schedules and sleep deprivation, as well as influence the basic cognitive processes, which modulate the performance of the individuals, such as attention, working memory and cognitive flexibility. This context can lead to reduced cognitive performance, impairing learning. In this work, we examine if the sleep habits, daytime sleepiness and cognition in adolescent attending to school at morning shifts vary in function of the media usage. Thus, 83 (60 girls, 23 boys) second grade high school students of private schools in Natal/RN answered questionnaires (Health and Sleep, Horne and ?stberg?s Morningness-Eveningness Questionaire and Epworth Sleepiness Scale) and a battery cognitive tests (evaluation of attention by a continuous performance task, working memory, the subtest of digits, and cognitive flexibility for trail making and Berg?s card sorting test). In addition, they completed the sleep diary for 10 days and daily media use log for two weekdays and two weekend days. Overall, media usage was higher in the weekend compared to the weekdays, and the most widely used device is the mobile phone, followed by television and computer. There were no correlations between the estimated weekly use of media and the parameters related to sleep. However, weak correlations were found between the weekly estimate and use: the overall stability in attention (r = -0.23; p <0.05), points (r = 0.22; p <0.05) and total score (r = 0.22; p <0.05) in the direct order of the digit subtest, and the isolated errors (r = -0.26; p <0.01) on Berg?s test. Concerning frequency of media use before bed, television appears as the preferred device for the group that have the higher frequency media use before bed (G3). The schedules of bedtime, wake up time and time in bed, in general, differ between weekdays and weekend (ANOVA, p<0,05). Overall, the G1 individuals have sleep patterns with more advanced times when compared to adolescents from others groups. G1 differ from others groups in wake up time in the weekend (ANOVA, p<0,05) and from G3 in time in bed on week (ANOVA, p<0,05 ? Bonferroni, p=0,06). Most students had excessive daytime sleepiness, with differences in proportions between groups. However, the highest percentages were observed successively in G1 and G3 (X?, p <0.05). For performance on cognitive tests, the G1 had a lower percentage of omissions in phasic alert (Mann-Whitney test, p <0.05), a tendency to a lower percentage of omissions in relation to the sustained attention (Kruskal-Wallis, p = 0 , 06), most points in the indirect order of the digit subtest (Mann-Whitney test, p <0.05) and greater efficiency in version A of the trail making test (Mann-Whitney test, p <0.05 ). Overall, these results support our hypothesis that the media use affects sleep, daytime sleepiness and cognitive performance, especially when the use of electronic devices occurs near the bedtime schedules. However, further studies with a larger number of individuals is required to confirm this evidence.

Conclui-se que o jornalismo local passou por v?rias mudan?as no que diz respeito ?s formas de produ??o, circula??o, gest?o de conte?do, capta??o de receitas e relacionamento com o p?blico e fontes, mas tamb?m foi marcado por perman?ncias, sobretudo, no que se refere a gest?o das pessoas que atuam nas reda??es. Hor?rios foram antecipados em virtude do privil?gio ? informa??o online; plataformas e aplicativos foram introduzidos na produ??o, circula??o e gest?o de conte?do e de tarefas; fun??es foram extintas; novas formas de capta??o e diversifica??o de receita foram testadas; edi??es em papel foram encerradas e uma empresa jornal?stica fechou no per?odo analisado, evidenciando uma reconfigura??o da forma de se praticar jornalismo em Natal (RN). Essas altera??es n?o se reverteram na atualiza??o da gest?o de pessoas, ?rea respons?vel por administrar e manter as mudan?as e garantir que os profissionais estejam treinados e motivados para vivenciar esse momento marcado pela hipercompetitividade e fluidez nos processos. / We plat the changes and continuities in Journalism in Natal (RN), considering the mapping field of the news companies Tribuna do Norte, Novo and O Jornal de Hoje (in Natal, capital city of Rio Grande do Norte - Brazil) and we investigate the changes and continuities in the production routine, from the preparation of the agenda to the production and circulation of content, starting at the association of symbolic cartography (SANTOS, 1998; 2011) up to the methods and techniques such as systematic observation, questionnaires and interviews in depth. We conclude that local journalism has undergone several changes regarding the forms of production, circulation, content management, revenue captation and relationship with the audience and sources, but was also marked by continuities, especially regarding the management of people who work in editorial rooms. Deadlines were anticipated due to the privilege to online information; platforms and applications were introduced in production, circulation and content and task management; functions were extinguished; new forms of funding and revenue diversification were tested; printed editions were eliminated and a news company closed during the period analyzed, making evident a reconfiguration of the way of practicing journalism in Natal (RN). These changes did not turn into updating the people management area responsible for managing and maintaining the changes and ensure that professionals are trained and motivated to experience this moment marked by hypercompetitiveness and fluidity in the processes.
