Bloggen - socialt medium med makt potential : <em>En kvalitativ studie om konsumtionsideal bland svenska och internationella bloggar</em> / The Blog - a social media with power potential : A qualitative study on consumption ideals among Swedish and international blogs

Lindmark, Malin, Beijer, Josefin January 2010 (has links)
<p>Today, we live in a consumption society. We buy products to soothe our needs and desires. Thru material things we can express our own personal identity and shopping is seen more as a pleasure than a need to survive.</p><p> </p><p>With the background media- and communication studies, the reason of this study was to explore how blogs as a social medium can influence the consumption ideal in society<strong>. </strong>With dialogical analysis and semiotic analysis we wanted to see if we could find a specific consumption culture in the content of six blogs we did our studies on. We found that the blogs showed us that there is normal to have everyday luxury and spoil oneself with expensive things. However, some of the result clearly shows that there is a difference between the Swedish and the international blogs.</p>

För vilka finns kroppspositivismen? : En diskursanalytisk och semiotisk studie av hur kroppsaktivister på Instagram artikulerar kroppspositivism / Who are included in the body positive movement? : A discourse analysis and a semiotic analysis of how body activists on Instagram articulate body positivity

Wallén, Camilla January 2017 (has links)
Denna studie har genomförts med syfte att undersöka hur kroppsaktivister artikulerar kropp och kroppspositivitet genom bilder och texter på deras Instagramkonton. Studien syftar även till att undersöka om, och i så fall hur, artikulationerna av kroppspositivitet skiljer sig mellan olika kroppsaktivister. Slutligen syftar studien till att studera hur kroppsaktivisterna artikulerar syftet med rörelsen. Det teoretiska ramverket består av tidigare forskning och etablerade teorier i postmodern feminism, fat studies, aktivism och objektifiering. Studien har genomförts med ett kvalitativt förhållningssätt och utförts genom en diskursanalys och semiotisk bildanalys av text och bild från tolv svenska kroppsaktivister på Instagram. Resultatet av studien visade att det finns olika åsikter kring vilka kroppar som får vara med i den kroppspositiva rörelsen. En del för en diskussion kring att den endast är till för personer med normbrytande kroppar, medan andra menar att den är till för alla kroppar. Studien visade även att kroppsaktivisterna visualiserar sina kroppar på olika sätt. En del tar bilder som liknar hur kvinnor porträtteras i reklam medan andra tar bilder som bryter mot normer genom val av vinkel och posering. Slutligen visade studien att kroppsaktivisterna ser olika på vilket syfte rörelsen har. Vissa för en diskussion kring att rörelsen ska få andra att må bra i sin egen kropp, andra om att medierna ska visa upp fler kroppstyper. Andra talar om att kroppspositivismen finns för att kvinnokroppen ska sluta utstå objektifiering. / This study has been conducted with the purpose of examining how body activists articulate body and body positivity through imagery and text on their Instagram accounts. This study also aims to investigate if the articulations of body positivity differ, and if so how. Finally, the study aims to examine how body activists articulates the purpose of the movement. The theoretical framework of this study is based on past research and established theories about postmodern feminism, fat studies, activism and objectification. The study has had a qualitative approach and is based on discourse analysis and a semiotic analysis of texts and images from twelve swedish body activists on Instagram. The result of the study showed that there are different opinions regarding which bodies that can be included in the body positive movement. Some of the participants argued that the movement includes all body types, while some argued that the movement should only include norm-breaking types of bodies. The study also showed that the body activists articulates their bodies in different ways. Some of the participants have taken pictures similar to how women are portrayed in advertisements while others have taken norm-breaking types of pictures by the choice of angle and pose. Finally, the study showed that the body activists have a different point of view regarding the purpose of the movement. For some of the body activists the aim of the movement is to make others feel good about their own body while others wants to see more body types in the media. Some of the participants feels that the purpose is to stop objectification of the female body.

Sémiotická analýza vybraných reklam na kosmetické produkty / Semiotic analysis of particular cosmetic products'commercials

Malá, Zuzana January 2014 (has links)
This diploma thesis deals with semiotics (the study of signs) in audiovisual commercials. In its theoretical part it is engaged in the field of semiotics. At this point it investigates mainly the problems of a sign, the key element of semiotics. Furthermore it follows the development of the knowledge acquired through semiotics to other areas of research which help to detect the meanings of communication. Those areas are the levels of signification, thus denotation, connotation and myth. This chapter especially draws on Roland Barthes and his publication Mythology, which inspired this diploma thesis. The theoretical part continues by explanation of the main problems of commercial. It gives out the definition of a commercial, explains commercial as a communication process, but also depicts the strategies used in a commercial. Furthermore it tells about conceptualization of a commercial by Jean Baudrillard. Since the thesis analyses audiovisual commercials, it also deals with the sound and picture of a commercial. In its practical part the thesis continues with the analysis of seven audiovisual cosmetic products' commercials itself. Semiotic analysis is done according to Barthes' model. The thesis describes each commercial's story, scene, and sounds, and then analyses those elements as well as the...

Krajiny paměti ve středoevropské literatuře - Halič a Bukovina / Memory lanscapes in centraleuropean literature - Galicia and Bukovina

Iljašenko, Marie January 2011 (has links)
MA thesis Memory landscapes in centraleuropean literature - Galicia and Bukovina is dedicated to an analysis of the links between landscape, text, memory and cultural identity. Using cultural-semiotic and comparative approaches, it delimits and examines the mnemonic constructs that appear in German written, Polish and Ukrainian literature related to the regions. Two, mostly theoretical chapters are dedicated to the chosen approaches. The order of examined texts follows the development of mnemonic constructs, a process that takes place in all the literatures. The constructs were developed after Galicia and Bukovina ceased to be a part of one of the states. The thesis' structure is topical, each chapter includes an account of German written, Polish and Ukrainian literature. The first chapter focuses on the imaginary topography, geography and symbolic landscapes of Galicia and Bukovina. The second chapter examines the cultural identity that is anchored in the mnemonic constructs. The third chapter concentrates on various myths, constructs and literary phenomena that contributed to the image of Galicia and Bukovina as memory landscapes.

Doležalová, Nikola January 2013 (has links)
This thesis focuses on the ways of depicting female beauty in ELLE magazine. In the theoretical part, the concept of beauty is defined and the development of the ideal of beauty and the influence of the media on people are described. The attitudes and research on beauty in the media are mentioned and primarily the emphasis is put on depiction of female beauty in the media. The reasons for women accepting the ideal of beauty presented by the media, the real nature of beauty in the media and the possible influence on women's self-esteem are dealt with, as well. The thesis also introduces the development of female magazines and their current role on the Czech market. At the end of the thesis, the campaigns aiming at unreal ideal of beauty in the media are critically evaluated. Mixed research method is used in the thesis; by means of the content analysis the photos of women (in advertisements as well as other pictures) are investigated with emphasis on their characteristics and in connection with the topic of the articles. The semiotic analysis examines the front pages and the message they convey. The aim of the analysis was to determine the most frequent depiction of women and to establish the proportion of articles dealing with appearance.

[en] SUPPORTING THE HCI DESIGNERS DECISION-MAKING ABOUT THE DESIGN OF EXTENSIBLE USER INTERFACES / [pt] APOIANDO O DESIGNER DE IHC NA TOMADA DE DECISÃO SOBRE O DESIGN DE INTERFACES EXTENSÍVEIS

ARIANE MORAES BUENO 22 October 2008 (has links)
[pt] Um dos grandes problemas no desenvolvimento de software é atender a todas as necessidades específicas de cada usuário em um domínio. A pesquisa sobre sistemas extensíveis tenta resolver este problema. Sistemas extensíveis são desenvolvidos de maneira que possam ser configurados pelos usuários finais, adicionando, modificando ou removendo funcionalidades e, assim, evoluir com o tempo. Uma área de pesquisa relacionada a aplicações extensíveis para pessoas experts no domínio, mas que não são profissionais de programação, é a de desenvolvimento por usuários finais (End-User Development - EUD). No entanto, não se encontra na literatura pesquisas que visem especificamente apoiar o designer na tomada de decisões sobre quando é interessante estender o sistema e qual parte dele poderá sofrer tal extensão. O objetivo deste trabalho é informar o designer sobre diferentes oportunidades de extensão relacionadas ao resultado da análise de tarefas e de usuários. Para isto, ele apresenta uma classificação, baseada na Engenharia Semiótica, que abrange as técnicas e aplicações extensíveis pesquisadas. Depois, ele identifica nas perguntas da análise de usuários e tarefas, quais se relacionam com as técnicas descritas nesta classificação. Assim, o designer pode identificar em que situações e quais métodos podem ser usados para estender o sistema. Para avaliar esta proposta, desenvolvemos um estudo de caso para reprojetar a ferramenta de autoria Composer, com o objetivo de mantê-la flexível e extensível, sem exigir muito conhecimento dos usuários sobre a linguagem subjacente ao domínio do sistema, a NCL (Nested Context Language). / [en] One of the major problems of software development is to pay attention to all specific needs of each user in a domain. The proposal to use extensible applications tries to solve this problem. Extensible systems are developed so that they can be shaped by end-users, adding, modifying or removing functionalities, and so evolve in time. A research area related to extensible applications for domain expert users who are not programming professionals is that of End User Development - EUD. However, it is not found in the literature, research that specifically support the designer in making decisions about when it is interesting to extend the system and which part of it can be extended. The purpose of this work is to inform the designer about different extension opportunities related to the result of user and task analysis. It presents a classification, based on Semiotic Engineering, which encompasses the investigated techniques and the extensible applications. Then, it identifies, in the user and task analysis questions, those related to the techniques described in this classification. Therefore, the designer can identify which approaches can be used in which situations to extend the system. To evaluate this proposal, we developed a case study to re-build an authoring tool for interactive multimedia programs called Composer. The study goal was to keep the application flexible and extensible without requiring from users too much knowledge about the application´s underlying language - the NCL (Nested Context Language).

[en] RECOMMENDER SYSTEM TO SUPPORT CHART CONSTRUCTIONS WITH STATISTICAL DATA / [pt] SISTEMA DE RECOMENDAÇÃO PARA APOIAR A CONSTRUÇÃO DE GRÁFICOS COM DADOS ESTATÍSTICOS

TAISSA ABDALLA FILGUEIRAS DE SOUSA 13 September 2013 (has links)
[pt] Pesquisas sobre visualização de dados estatísticos demonstram a necessidade de sistemas que apóiem tomadas da decisões e análises visuais. Constatando problemas de construção de visualizações por usuários inexperientes, nossa questão de pesquisa foi: Como apoiar usuários inexperientes na construção de visualizações eficientes com dados estatísticos? Assim, desenvolvemos ViSC, um sistema de recomendações que apóia a construção interativa de gráficos para visualizar dados estatísticos, através de uma série de recomendações baseadas nos dados selecionados e na interação do usuário com a ferramenta. O sistema explora uma ontologia de visualização para oferecer um conjunto de gráficos que ajudam a responder questões baseadas em informação relacionadas aos dados exibidos no gráfico. Percorrendo os gráficos recomendados através de suas questões relacionadas, o usuário implicitamente adquire conhecimento tanto do domínio quanto dos recursos de visualização que melhor representam os conceitos do domínio de interesse. Esta dissertação apresenta os problemas que motivaram a pesquisa, descreve a ferramenta ViSC e apresenta os resultados de uma pesquisa qualitativa realizada para avaliar ViSC. Para a avaliação, utilizamos o Método de Inspeção Semiótica (MIS) e o Retrospective Communicability Evaluation (RCE) — uma combinação do Método de Avaliação da Comunicabilidade (MAC) e Retrospective Think Aloud Protocol. Concentramo-nos em verificar como as recomendações influenciam na realização de uma tarefa e nas visualizações geradas para então endereçar nossa questão mais ampla. / [en] Research on statistical data visualization emphasizes the need for systems that assist in decision-making and visual analysis. Having found problems in chart construction by novice users, we decided to research the following question: How can we support novice users to create efficient visualizations with statistical data? Thus we, created ViSC, a recommender system that supports the interactive construction of charts to visualize statistical data by offering a series of recommendations based on the selected data and the user interaction with the tool. The system explores a visualization ontology to offer a set of graphs that help to answer information-based questions related to the current graph data. By traversing the recommended graphs through their related questions, the user implicitly acquires knowledge both on the domain and on visualization resources that better represent the domain concepts of interest. This dissertation presents the problems that motivated the research, describes the ViSC tool and presents the results of a qualitative study conducted to evaluate ViSC. We used two methods in our evaluation: the Semiotic Inspection Method (SIM) and the Retrospective Communicability Evaluation (RCE) — a combination of the Communicability Evaluation Method (CEM) and Retrospective Think Aloud Protocol. We first analyze how the questions influence the users traversal through the graph and, then, we address the broader question.

[en] POLIFACETS: A DESIGN MODEL FOR THE METACOMMUNICATION OF ACTIVE DOCUMENTS TO SUPPORT TEACHING AND LEARNING OF COMPUTER PROGRAMMING / [pt] POLIFACETS: UM MODELO DE DESIGN DA METACOMUNICAÇÃO DE DOCUMENTOS ATIVOS PARA APOIAR O ENSINO E APRENDIZADO DE PROGRAMAÇÃO

MARCELLE PEREIRA MOTA 06 October 2014 (has links)
[pt] Atualmente há uma necessidade de uso da tecnologia para efetivar a participação do cidadão na sociedade. Os usuários estão deixando de ser somente consumidores passivos de software e uma fração crescente deles já passa a usar a tecnologia como um meio de expressão de novas ideias e oportunidades. Em um cenário democrático de futuro, quantas mais pessoas puderem manifestar-se através do uso eficaz e eficiente de tecnologia, menor o risco de que aqueles que podem fazê-lo determinem o que os demais poderão fazer. Porém, o processo de ensino e aprendizado de raciocínio computacional, base de competência para a autoexpressão através de software, é um grande desafio. Os professores de escolas de ensino fundamental e médio, por exemplo, geralmente não têm formação ou auxílio para ensinar conteúdos que envolvem conceitos de computação com os quais não estão familiarizados e, portanto, precisam, eles próprios, aprender. Esta tese apresenta um modelo para o design de documentação ativa destinada a apoiar o ensino e aprendizado de raciocínio computacional. O modelo é baseado em Engenharia Semiótica e sua instanciação em um cenário real de uso resultou em um documento utilizado em vários estudos empíricos realizados ao longo de três anos, em escolas de ensino fundamental e médio na região metropolitana do Rio de Janeiro. Na dimensão técnico-científica, a principal contribuição da tese é uma ferramenta epistêmica para estruturar as análises e decisões durante o design da metacomunicação de documentos ativos destinados a apoiar o ensino e aprendizado de autoexpressão através de software. / [en] Nowadays, there is a need to use technology to effect citizen participation in society. Users are no longer only passive software consumers and a growing share of them are using technology as a medium to express new ideas and opportunities. In a democratic future scenario, the more people can manifest themselves through the effective and efficient use of technology, the lower the risk that those who can do it determine what others will do. However, the process of teaching and learning computational thinking, which is the basic skill for self-expression through software, is a big challenge. Teachers need to learn computational concepts themselves before they can teach them to students. In elementary and high school they generally do not have support for teaching this kind of content. This thesis presents a model for the design of active documentation which aims at supporting the teaching and learning of computational thinking. The model is based on Semiotic Engineering theory and its instantiation in a real scenario came about as an active document used in several empirical studies during three years with elementary and high schools in the metropolitan region of Rio de Janeiro. Technically and scientifically, the main contribution of this thesis is an epistemic tool for structure analyses and decisions during the design of metacommunication of active documents to support the teaching and learning of self-expression through software.

[en] EXTREME COMMUNICATION-CENTERED DESIGN: AN AGILE PROCESS FOR HUMANCOMPUTER INTERACTION DESIGN / [pt] EXTREME COMMUNICATION-CENTERED DESIGN: UM PROCESSO ÁGIL PARA O PROJETO DA INTERAÇÃO HUMANO-COMPUTADOR

VIVIANE CRISTINA OLIVEIRA AURELIANO 26 December 2007 (has links)
[pt] O desenvolvimento de software interativo pode seguir diferentes tipos de processos, que vão desde os voltados a especificação (métodos tradicionais) àqueles voltados a prototipação (métodos ágeis). Em virtude da ênfase em documentação desde suas fases iniciais, os métodos tradicionais permitem uma maior reflexão sobre o software antes de sua implementação e contribuem para uma melhor manutenibilidade. Já os métodos ágeis têm uma quantidade de documentação reduzida, focando principalmente a implementação do sistema, a fim de trazer uma maior produtividade a este processo. À medida que os softwares se tornam mais interativos e acessíveis aos mais diversos usuários, preocupações com a interação humano-computador (IHC) vêm ganhando destaque no processo de desenvolvimento de software. No entanto, restrições de prazo e orçamento acabam por limitar a aplicação de técnicas e teorias de IHC já bem estabelecidas. Em conseqüência, semelhante ao que ocorreu com os processos de desenvolvimento de software, uma tendência tem sido a adoção de práticas de usabilidade mais simplificadas, tais como listas de verificação e diretrizes. No sentido de lidar com tais preocupações ainda em tempo de projeto e de uma maneira não tão simplificada, este trabalho incorpora algumas vantagens dos processos de desenvolvimento de software para definir um processo para o projeto de IHC. Tal processo busca unir o apoio à reflexão oferecido pela teoria da Engenharia Semiótica (EngSem) com a característica de agilidade de técnicas de prototipação de interfaces, incorporando os valores e princípios dos métodos ágeis, mais especificamente do processo de desenvolvimento eXtreme Programming (XP). / [en] Interactive software development can follow different kinds of processes, from specification-driven approaches (traditional methods) to prototype-driven approaches (agile methods). Due to the emphasis in documentation since its initial phases, traditional methods allow for more reflection on the software before its implementation and contribute to better maintainability. On the other hand, agile methods have reduced documentation, concentrating mainly on the implementation of the system, in order to increase the productivity in the software development process. As software becomes more interactive and accessible to a wider range of users, human-computer interaction (HCI) concerns have been gaining emphasis in the software development process. However, schedule and budget restrictions limit the application of known and accepted HCI techniques. As a consequence, and similar to what happened with software development processes, there has been a tendency to adopt simplified usability practices, such as checklists and guidelines. In order to deal with such concerns at design time, and in a way that is not so simplified, this work unites some advantages of different kinds of software development processes to define an HCI design process. This process brings together the support for reflection given by the Semiotic Engineering (SemEng) theory and the agility of interface prototype techniques, incorporating the values and practices from agile methods, more specifically of the eXtreme Programming (XP) development process.

[en] COMUNIHC-ES: AN HCI TOOL TO SUPPORT THE COMMUNICATION BETWEEN HCI PROFESSIONALS AND SOFTWARE ENGINEERS / [pt] COMUNIHC-ES: FERRAMENTA DE APOIO À COMUNICAÇÃO ENTRE PROFISSIONAIS DE IHC E ENGENHEIROS DE SOFTWARE

MAIRA GRECO DE PAULA 31 March 2008 (has links)
[pt] O desenvolvimento de sistemas interativos envolve profissionais de várias áreas, dentre as quais interação humano-computador (IHC) e engenharia de software (ESw), cada qual com o seu foco e objetivo. IHC se concentra, de modo geral, em entender as características, necessidades e objetivos dos usuários da aplicação, o seu ambiente de trabalho e as tarefas que eles precisam ou desejam realizar através do sistema. A partir deste entendimento, IHC projeta a interface e interação, tendo como atividade constante a avaliação dos artefatos produzidos. Já a ESw tem como principal objetivo a especificação, implementação e testes das funcionalidades e arquitetura do sistema interativo. Essas duas áreas possuem um objetivo comum: a criação de um sistema interativo que atenda bem as necessidades dos usuários da aplicação. Para alcançar esse objetivo, este trabalho supõe que a comunicação entre os profissionais dessas áreas durante o processo de desenvolvimento é necessária para que se possa criar um entendimento compartilhado do problema e do que deve ser construído e, conseqüentemente, para que a camada de aplicação desenvolvida seja compatível com a camada de interação, mantendo-se a consistência do que será apresentado para o usuário final. Então, para apoiar a comunicação e negociação sobre o projeto da interação entre as áreas de IHC e ESw, esta pesquisa propõe uma ferramenta de comunicação fundamentada na engenharia semiótica, a ComunIHC-ES. Essa ferramenta contém informações sobre o domínio em questão, seus usuários, as tarefas envolvidas e o contexto de uso; uma linguagem para se projetar a interação; e elementos para apoiar a explicação deste projeto para os engenheiros de software. A ComunIHC-ES foi utilizada em um estudo de caso envolvendo profissionais dessas duas áreas e, após a análise dos resultados, obteve-se indícios de sua utilidade no apoio à comunicação e ao trabalho dos engenheiros de software. / [en] Developing interactive systems involves professionals from many areas of expertise, including HCI (Human-Computer Interaction) and Software Engineering (SE), each one with specific focus and goals. HCI focuses, generally, on understanding the users` characteristics, needs and objectives, their work environment and the tasks they need or want to perform using the system. Based on this understanding, HCI designs interface and interaction, constantly evaluating the produced artifacts. SE, on the other hand, aims primarily at specifying, implementing and testing the interactive system`s functionalities and architecture. These two areas have a common objective: to create an interactive system that meets the needs of its users. To attain this goal, this work supposes that, throughout the development process, communication is needed between the professionals from these areas, in order to create a shared understanding about the problem and about what should be built, so that, consequently, the developed application layer will be compatible with the interaction layer, promoting the consistency of what will be presented to the end user. Thus, to support both the communication and the negotiation about interaction design between HCI and SE professionals, this research proposes a communication tool based on semiotic engineering, called ComunIHC-ES. This tool contains information about the problem domain, its users, the tasks involved and the usage context; a language to represent the interaction; and elements that help to explain the HCI design to software engineers. ComunIHC-ES was used in a case study involving professionals from both areas and, after analyzing its results, indications were obtained of its usefulness in supporting both the HCISE communication and the software engineers work.
