Aus gesellschaftspolitischer und wissenschaftlicher Perspektive wird die Bedeutung digitaler Informations- und Kommunikationstechnologien (IKT) für Schule und Unterricht diskutiert. Dabei wird vor allem das Potenzial digitaler Medien zur Unterstützung konstruktivistischer Lehr-Lernprinizipien im Rahmen kooperativen und verständnisorientierten Unterrichts betont. Empirische Ergebnisse zeigen allerdings, dass das vorhandene Potenzial keineswegs ausgeschöpft wird. Im Rahmen der Lehrerkognitionsforschung wird angenommen, dass bewusste und weniger bewusste Kognitionen das unterrichtliche Handeln der Lehrpersonen determinieren. Vor diesem Hintergrund werden handlungsleitende Kognitionen von Lehrpersonen als Bedingungsfaktoren der Medienintegration in den Unterricht angesehen. In der vorliegenden Arbeit werden handlungsleitenden Kognitionen von Lehrpersonen beim Einsatz digitaler Medien im Unterricht rekonstruiert und das Verhältnis dieser zueinander analysiert. Im theoretischen Teil erfolgt die Beschreibung und Diskussion handlungsleitender Kognitionen von Lehrpersonen sowie von Unterricht. Dieser wird sowohl aus pädagogisch-psychologischer als auch didaktischer Perspektive beschrieben. Auf der Grundlage von Video- und Interviewdaten von Lehrpersonen der Sekundarstufe II, werden mithilfe inhaltsanalytischer und typisierender Verfahren drei differenzierte Überzeugungs- und drei Skriptmuster identifiziert. Die Unterrichtsskripts der Lehrpersonen unterscheiden sich in Bezug auf das Ausmaß der Lehrerlenkung, die Medienfunktion und -steuerung sowie hinsichtlich der Lehrer-Schüler-Interaktion. Die Überzeugungen der Lehrperso-nen unterscheiden sich in Bezug auf die angestrebte Lehrer- bzw. Schüler-Rolle und hinsichtlich der angestrebten Nutzung digitaler Medien im Unterricht. Es zeigen sich Übereinstimmungen zwischen Überzeugungen und Skripts, die auf zentrale lehr-lerntheoretische Vorstellungen zurückgeführt werden. / From a socio-political as well as scientific perspective the relevance of information and communication technology (ICT) for teaching and learning is often discussed. These discussions mostly center on the issue of the innovation of teaching and learning by the use of digital media. However, empirical studies indicate that teachers do not take advantage of the full potential of ICT in their teaching. Within the framework of teacher cognition research it is often assumed that the realized teaching behavior of teachers is determined by cognitions that guide the teaching. These cognitions have been further differentiated into beliefs on the one hand and automated cognitions (so called scripts) on the other. Thus, both constructs can serve as important indicators for the quality of media integration in teachers’ teaching. This study aims at the identification of guiding cognitions of teachers when using digital media at school. In the theoretical section the construct of teacher cognition is discussed and a framework for the reconstruction of teacher cognition is developed using both didactical concepts as well as results of instructional research. Based on interview and video data three different configurations of beliefs and scripts have been identified using typifying methods as well as content analysis. These scripts differ from each other with respect to the extent of teacher direction, the function and control of media in instruction and the type of teacher-student-interaction. The analysis of the teacher interviews indicates that the classroom behavior of teachers is based on a complex belief-system. The three types of teachers beliefs differ mainly in the perspective of the teacher- and student-role and in the perceived benefit of ICT for instruction. Overall, this study shows that teachers’ use of ICT in instruction is based on and directed by different guiding cognitions which can be described and typified from the perspective of teaching and learning.

Titel: Is sharing caring? En kvantitativ studie om intentionen att dela virala videor   Nivå: Examensarbete på Grundnivå (kandidatexamen) i ämnet företagsekonomi   Författare: Amanda Happ och Erik Wilhelmsson   Handledare: Jonas Kågström   Datum: 2019 – Januari   Syfte: Syftet med studien är att analysera faktorerna bakom intentionen att dela en viral video på internet utifrån begreppen videokvalitet, empati, kontroll, altruism och inkludering. Studien genomförs således för att bidra med kunskap om intentionen bakom virala videodelningar till marknadsförare inom ämnet.   Metod: En kvantitativ metod har använts där data har samlats in genom en webbaserad enkätundersökning med 480 kvinnliga respondenter från 16 år och uppåt. Data har bearbetats i analys- och statistikprogrammet SPSS genom deskriptiv-, faktor-, kluster- och korrelationsanalys.   Resultat & slutsats: Resultatet visar att inkludering, altruism och i viss mån kontroll är de främsta faktorerna för att skapa en intention att dela virala videor på internet. Vidare visar resultatet att personer som väljer att dela virala videor med sina vänner ofta vill uppnå förstärkta band till gruppens medlemmar och bekräftelse av sin egen roll i den sociala gruppen.   Examensarbetets bidrag: Studien bidrar till ökad kunskap om vilka beteendefaktorer som ligger bakom beslutet att dela en viral video på internet. Denna kunskap kan hjälpa yrkesutövare skapa en marknadsföringskampanj som har till syfte att bli viral på internet.      Förslag till fortsatt forskning: Fortsatt forskning bör rikta sig till andra målgrupper, förslagsvis män. Det är även relevant att utföra en större undersökning där intentionen hos både sändare och mottagare (som i sin tur delar videon vidare) analyseras för att kunna påträffa eventuella likheter och skillnader hos dessa olika grupper.   Nyckelord: Virala videor, delning, eWOM, FIRO, Moment-to-Moment Likeability / Title: Is sharing caring? A quantitative study about the intention behind sharing viral videos.   Level: Student thesis, final assignment for bachelor’s degree in business administration.   Author: Amanda Happ and Erik Wilhelmsson   Supervisor: Jonas Kågström   Date: 2019 – January   Aim: The aim of this paper is to analyze factors behind the intention to share a viral video on the internet based on the concepts of video quality, empathy, control, altruism and inclusion.  This paper aims to contribute knowledge of the intention behind sharing viral videos to marketers within the subject.   Method: A quantitative method has been performed where data has been collected through a web-based survey of 480 female respondents from 16 years and older. Data has been processed in the analysis- and statistical program SPSS by using descriptive-, factor-, cluster- and correlation analysis.   Result & Conclusions: The result shows that inclusion, altruism and, to some extent, control are the main factors for creating an intention to share viral videos on the internet. Furthermore, the result shows that people who choose to share viral videos with their friends often want to strengthen ties to other group members and reinforce their role in the social group.   Contribution of the thesis: The study contributes to increased knowledge of the behavioral factors behind the decision to share a viral video. Knowledge can help professionals when a marketing campaign is being created with the aim of becoming viral on the internet.   Suggestions for future research: Continued research should target other groups, preferably men. It is also relevant to conduct a larger survey where the intention of both creator and receiver of viral content are analyzed to identify any similarities and differences between them.   Key words: Viral videos, forwarding intention, eWOM, FIRO, Moment-to-Moment Likeability

La création des vidéos panoramiques de haute qualité pour des contenus immersifs en VR est généralement faite à l'aide d'un appareil doté de plusieurs caméras couvrant une scène cible. Malheureusement, cette configuration introduit à la fois des artefacts spatiaux et temporels dus à la différence entre les centres optiques et à la synchronisation imparfaite. Les mesures de qualité d'image traditionnelles ne peuvent pas être utilisées pour évaluer la qualité de ces vidéos, en raison de leur incapacité à capturer des distorsions géométriques. Dans cette thèse, nous proposons des méthodes pour l'évaluation objective des vidéos panoramiques basées sur le flux optique et la saillance visuelle. Nous validons cette métrique avec une étude centrée sur l'homme qui combine l'annotation d'erreurs percues et l'eye-tracking.Un défi important pour mesurer la qualité des vidéos panoramiques est le manque d'une vérité-terrain. Nous avons étudié l'utilisation des vidéos originales comme référence pour le panorama de sortie. Nous notons que cette approche n'est pas directement applicable, car chaque pixel du panorama final peut avoir une à $N$ sources correspondant à $N$ vidéos d'entrée avec des régions se chevauchant. Nous montrons que ce problème peut être résolu en calculant l'écart type des déplacements de tous les pixels sources à partir du déplacement du panorama en tant que mesure de la distorsion. Cela permet de comparer la différence de mouvement entre deux images données dans les vidéos originales et le mouvement dans le panorama final. Les cartes de saillance basées sur la perception humaine sont utilisées pour pondérer la carte de distorsion pour un filtrage plus précis.Cette méthode a été validée par une étude centrée sur l'homme utilisant une expérience empirique. L'expérience visait à déterminer si les humains et la métrique d'évaluation détectaient et mesuraient les mêmes erreurs, et à explorer quelles erreurs sont les plus importantes pour les humains lorsqu'ils regardent une vidéo panoramique.Les méthodes décrites ont été testées et validées et fournissent des résultats intéressants en ce qui concerne la perception humaine pour les mesures de qualité. Ils ouvrent également la voie à de nouvelles méthodes d'optimisation de l'assemblage vidéo, guidées par ces mesures de qualité. / High quality panoramic videos for immersive VR content are commonly created using a rig with multiple cameras covering a target scene. Unfortunately, this setup introduces both spatial and temporal artifacts due to the difference in optical centers as well as the imperfect synchronization. Traditional image quality metrics cannot be used to assess the quality of such videos, due to their inability to capture geometric distortions. In this thesis, we propose methods for the objective assessment of panoramic videos based on optical flow and visual salience. We validate this metric with a human-centered study that combines human error annotation and eye-tracking.An important challenge in measuring quality for panoramic videos is the lack of ground truth. We have investigated the use of the original videos as a reference for the output panorama. We note that this approach is not directly applicable, because each pixel in the final panorama can have one to N sources corresponding to N input videos with overlapping regions. We show that this problem can be solved by calculating the standard deviation of displacements of all source pixels from the displacement of the panorama as a measure of distortion. This makes it possible to compare the difference in motion between two given frames in the original videos and motion in the final panorama. Salience maps based on human perception are used to weight the distortion map for more accurate filtering.This method was validated with a human-centered study using an empirical experiment. The experiment was designed to investigate whether humans and the evaluation metric detect and measure the same errors, and to explore which errors are more salient to humans when watching a panoramic video.The methods described have been tested and validated and they provide interesting findings regarding human-based perception for quality metrics. They also open the way to new methods for optimizing video stitching guided by those quality metrics.

Since then, the production and dissemination of popular videos and attained the dimension of teacher training. In this context, also emerged the concept of school productive and accessible to the whole population, leading the state to offer continued education policies for teachers of basic education, in order to alleviate problems of initial preparation of these teachers, preparing them for democratic society that loomed on the horizon. This analysis is a method contextualization of these programs, with a view to experiences that occurred in the state of Paraná, through critical reflection of the history of education and educational policies aimed at teaching task in Brazil. Founded in critical theories of curriculum, aims to shed light on processes called: continuing education, continuing education, in-service training offered to teachers of basic education through continuing education programs for videos of the 1990s. So, were used as sources the official texts, such as educational law, literature on the subject, testimony of teachers and graduates of these courses of the videos presented in these courses as an indication of our employees. Therefore, it was the following path: in the first part of the text, drew up an overview of the history of teacher education in Brazil since the first initiatives with the Jesuits (1530) until the period of the military dictatorship (1985), in second part, there was a discussion about teacher education in contemporary society and in the third part was tracing the methodological approach of qualitative research in education, in the fourth part we sought to deepen the understanding of the distance courses offered in the 1990s by of Teleaulas. It is considered that the training project presented in 1990, consistent with the historical tradition of lighter training of teachers in Brazil, especially for teachers of peripheral cities which, during life, had no access to proper qualification, fitting them training, retraining and in-service training. It is further considered that there is a certain optimism exacerbated by the use of information and communication technologies in teaching office and modernizing discourse that can camouflage conservative policies. Thus, the history of education can be a way of uncovering such processes in order to think about the present / Durante a metade da década de 1970, foi inventado o sistema VHS. Desde então, a produção e divulgação de vídeos popularizou-se e alcançou a dimensão da formação de professores. Nesse contexto, emergiu também a concepção de escola produtiva e acessível a toda população, conduzindo o Estado a ofertar políticas de formação continuada aos docentes da educação básica, com a finalidade de atenuar problemas da preparação inicial desses docentes, munindo-os para a sociedade democrática que avultava no horizonte. A presente análise tem como método a contextualização desses programas, com vistas às experiências ocorridas no estado do Paraná, por meio da reflexão crítica da história da educação e das políticas públicas de educação voltadas à tarefa docente no Brasil. Com fundamento nas teorias críticas do currículo, propõe-se lançar luz aos processos denominados: formação continuada; formação permanente; formação em serviço, ofertadas aos professores da educação básica por meio de programas de educação continuada por vídeos da década de 1990. Para tanto, foram utilizados como fontes os textos oficiais, como a legislação educacional, literatura a respeito do tema, depoimento de professores egressos desses cursos e parte dos vídeos apresentados nesses cursos, conforme indicação de nossos colaboradores. Para tanto, fez-se o seguinte percurso: na primeira parte do texto, traçou-se o panorama da história da formação de professores no Brasil desde as primeiras iniciativas com os Jesuítas (1530) até o período da Ditadura Militar (1985); na segunda parte, realizou-se uma discussão sobre a formação de professores na contemporaneidade; na terceira parte foi traçado o percurso metodológico da pesquisa qualitativa em educação; na quarta parte, buscou-se aprofundar o entendimento sobre os cursos ofertados a distância nos anos 1990 por meio das Teleaulas. Considera-se que o projeto formativo apresentado na década de 1990, coaduna com a tradição histórica de formação aligeirada de professores no Brasil, sobretudo aos docentes das cidades mais periféricas, que, durante a vida profissional, não tiveram acesso a qualificação adequada, cabendo-lhes o treinamento, a reciclagem e a formação em serviço. Considera-se, ainda, que há um certo otimismo exacerbado com o uso das tecnologias de informação e comunicação no ofício docente e que esse discurso modernizador pode camuflar políticas conservadoras. Dessa forma, a história da educação pode ser uma maneira de desvelar tais processos, a fim de pensar o presente

The work also tries to find some of these elements in audio-visual scripts. The dissertation has a qualitative approach and uses the following techniques: documental research, script analysis and four experiments conducted in public schools located in the city of São Paulo. The research shows that students acknowledge the videos as curriculum mediators; are able to identify specific characteristics of the media; and that these productions, when properly used by the teacher, are well received by pupils, enriching the reflection on the curriculum content / O objetivo geral deste trabalho é compreender como o vídeo educacional pode se integrar ao currículo e quais devem ser os elementos desse recurso. O objetivo específico é descobrir se é possível delinear algumas dessas características no roteiro do audiovisual. O estudo se orienta pelos princípios da abordagem qualitativa, e sua metodologia envolve pesquisa documental, análise de roteiros de vídeos educacionais e experiências em quatro escolas públicas municipais de São Paulo. A pesquisa mostra que os alunos reconhecem no vídeo um mediador curricular; identificam características específicas do meio audiovisual; e que as produções, quando apropriadas e contextualizadas pelo professor, são bem-vindas na sala de aula, enriquecendo as possibilidades de reflexão e de entendimento dos conteúdos curriculares

A evolução dos dispositivos de armazenamento e das redes de computadores permitiram que os vídeos digitais assumissem um importante papel no desenvolvimento de sistemas de informação multimídia. Com a finalidade de aproveitar todo o potencial dos vídeos digitais no desenvolvimento desses sistemas, técnicas automatizadas eficientes para análise, interpretação e recuperação são necessárias. A recuperação de vídeos baseada em conteúdo (CBVR, do inglês content-based video retrieval) permite o processamento e a análise do conteúdo de vídeos digitais visando à extração de informações relevantes que viabilizem indexação e recuperação. Trabalhos científicos têm proposto a aplicação de CBVR em bases de vídeos médicos a fim de proporcionar diferentes contribuições como diagnóstico auxiliado por computador, suporte à tomada de decisão e disponibilização de bases de vídeos para utilização em treinamento e educação médica. Em geral, características visuais são as principais informações utilizadas no contexto de CBVR aplicada em vídeos médicos. No entanto, muitos diagnósticos são realizados por meio da análise dos sons produzidos em diferentes estruturas e órgãos do corpo humano. Um exemplo é o diagnóstico cardíaco que, além de exames de imagem como ecocardiografia e ressonância magnética, também pode empregar a análise dos sons provenientes do coração por meio da auscultação. O objetivo deste trabalho consistiu em aplicar e avaliar extratores de características de som em conjunto com extratores de características visuais para viabilizar CBVR e, então, inferir se a abordagem resultou em ganhos com relação ao desempenho de recuperação quando comparada à utilização apenas das características visuais. Vídeos médicos constituíram nosso principal interesse, porém o trabalho considerou também vídeos não relacionados à área médica para a validação da abordagem. Justifica-se o objetivo, pois a análise do som, visando a obter descritores relevantes para melhorar os resultados de recuperação, ainda é pouco explorada na literatura científica. Essa afirmação foi evidenciada com a condução de uma revisão sistemática sobre o tema. Dois conjuntos de experimentos foram conduzidos visando a validar a abordagem de CBVR mencionada. O primeiro conjunto de experimentos foi aplicado sobre uma base de vídeos sintetizados para validação da abordagem. Já o segundo, foi aplicado em uma base de vídeos construídos utilizando-se imagens provenientes de exames de ressonância magnética em conjunto com sons provenientes de auscultação do coração. Os resultados foram analisados utilizando-se as métricas de revocação e precisão, bem como o gráfico que as relaciona. Demonstrou-se que a abordagem é promissora por meio da melhora significativa dos resultados de recuperação nos diferentes cenários de combinação entre características visuais e sonoras experimentados / Advance of storage devices and computer networks has contributed to digital videos assume an important role in the development of multimedia information systems. In order to take advantage of the full potential of digital videos in the development of these systems, it is necessary the development of efficient techniques for automated data analysis, interpretation and retrieval. Content-based video retrieval (CBVR) allows processing and analysis of content in digital videos to extract relevant information and enable indexing and retrieval. Scientific studies have proposed the application of CBVR in medical video databases in order to provide different contributions like computer-aided diagnosis, decision-making support or availability of video databases for use in medical training and education. In general, visual characteristics are the main information used in the context of CBVR applied in medical videos. However, many diagnoses are performed by analysing the sounds produced in different structures and organs of the human body. An example is the cardiac diagnosis which, in addition to images generated by echocardiography and magnetic resonance imaging, for example, may also employ the analysis of sounds from the heart by means of auscultation. The objective of this work was evaluating combination between audio signal and visual features to enable CBVR and investigating how much this approach can improve retrieval results comparing to using only visual features. Medical videos are the main data of interest in this work, but video segments not related to the medical field were also used to validate the approach. The objectives of this work are justifiable because audio signal analysis, in order to get relevant descriptors to improve retrieval results, is still little explored in the scientific literature. This statement was evidenced by results of a systematic review. Two experiment sets were conducted to validate the CBVR approach described. The first experiment set was applied to a synthetic images database specially built to validate the approach, while the second experiment was applied to a database composed of digital videos created from magnetic resonance imaging and heart sounds from auscultation. Results were analyzed using the recall and precision metrics, as well as the graph which relates these metrics. Results showed that this approach is promising due the significantly improvement obtained in retrieval results to different scenarios of combination between visual and audio signal features

A utilização de vídeos em laboratórios baseados em redes de computadores (weblabs) para pesquisa de abelhas está sendo conduzida como parte do projeto ViNCES (Virtual Network Center of Ecosystem Services), um consórcio de pesquisa composto pelo LAA (Laboratório de Automação Agrícola da Escola Politécnica da Universidade de São Paulo) e o Laboratório de Abelhas do Departamento de Ecologia do Instituto de Biociências da Universidade de São Paulo. O ViNCES é um membro do Kyatera, uma rede de computadores acadêmica de alta velocidade que tem como objetivos o desenvolvimento de aplicações e tecnologias para a Internet Avançada. Nesse contexto, o Weblab de abelhas, denominado BBBee, permite a realização de pesquisa e observação à distância da entrada de uma colméias, sendo coletadas e transmitidas informações de condições climáticas, de áudio e vídeo. O áudio e o vídeo da colméia são transmitidos em rede local e pela Internet por meio de streaming em tempo real. Os requisitos de largura de banda para transmissões de vídeo costumam ser elevados, e a qualidade obtida após o processo de compressão convencional, em geral, é baixa, podendo afetar ou dificultar a pesquisa. Além disso, está prevista a transmissão de vídeos de Alta Definição para weblab com o objetivo de melhorar a qualidade da informação, o que irá demandar maior largura de banda. Este trabalho propõe um algoritmo de codificação de vídeo para melhorar a qualidade das imagens transmitidas, ao mesmo tempo em que se reduzem os requisitos de largura de banda de transmissão e armazenagem, por meio da aplicação de técnicas de segmentação e rastreamento de objetos de vídeo. O algoritmo proposto foi implementado e testado utilizando vídeos capturados nas colméias e os resultados das análises em diversas condições são apresentados neste documento. Para avaliar a qualidade resultante do processo, foi utilizada uma métrica objetiva que permite avaliar a qualidade das imagens em relação às imagens de origem. Os resultados das análises proveram informações e direções para melhorias e futuras implementações. / The use of videos in web based laboratories over computer networks, known as weblabs, is being conducted for bee research as part of the ViNCES (Virtual Network Center of Ecosystem Services) project, a research consortium composed by: LAA (Laboratório de Automação Agrícola da Escola Politécnica) and the Laboratório de Abelhas of the Ecology Department of the Biosciences Institute. ViNCES is a member of Kyatera, a high speed academic computer network which aims at developing aplications and technologies for the Advanced Internet. The bee weblab, called BBBee, allows the research and observation of the interior of a beehive, in which are collected climate, audio and video data. Real time audio and video are broadcasted over the Internet and through a local network using streaming format. The bandwidth requirements for video transmission are usually high and the video quality after conventional compression standards is, in general, low and can interfere in the biological research. Also, High-Definition video transmission for weblab is planned to be implemented in order to provide better tools for the researcher, which will demand even higher network bandwidth. On this scenario, this work intends to provide a video codification algorithm to enhance the quality of the transmitted images, at the region of interest, and also reduce the transmission and storage requirements for some situations by using segmentation and tracking techniques for videos. A complete CODEC was implemented and tested with actual video, quality and data rates were measured and evaluated using an objective metric. The results of the analysis provided some indications of directions for future enhancements and implementations.

<p>This is a case study of the music channel MTV and it’s impact on the Swedish mediascape. We want to look into the process that lies behind this huge intercontinental corporation. Through literature studies we present the mechanism’s that paved the way for MTV growing into the number one music channel of modern time. To investigate how MTV was received in Sweden, we analyse articles taken from databases providing us with essential information about how Swedish journalist’s debate the issue. To show an assumed development within the Swedish mediascape we are using two different time periods, the first represents the year 1993 through to 1995 and the second, 2000 through 2003. These time periods are also used within statistical research included in this paper. This part shows the differences between MTV and other music channels that are competitors in the Swedish mediascape. Altogether these parts helps us to bring out topics that hopefully gives answers to our main quandary – what kind of effect has MTV had on the Swedish mediascape?</p>

<p>The intention of the essay was to see what Web users’ comprehension might be when watching four videos that are published on the Swedish Government’s Web site. One video contains an interview with Lena Hallengren, Minister for Youth Affairs of the Swedish Government, and in the other three Ulrica Messing, Minister for Communications and Regional Affairs of the same government, gives speeches about the governmental issues she is responsible for. </p><p>The comprehensions that were examined are those concerning the forms of presentation of the videos, the ministers’ appearances, the videos abilities to create and maintain the Web site visitors’ interest, and the visitors’ behaviours and conducts while being in contact with the Web site. The examination was carried out with the Stimulated Recall method, where the respondents’ memory of what they thought while they visited the Web site and watched the videos were collected, along with an interview where they interpreted what they had seen. </p><p>The analysis of the data was based on the theories of Marshall McLuhan, Jay D. Bolter & Richard Grusin, and Jacob Nielsen, which contain ideas about how new media incorporate older media, and how Web users comprehend and behave in their contact with the Internet. </p><p>The conclusion was that the respondents had low interest in Lena Hallengren’s video because it was too long and made them inactive. Ulrica Messing’s appearance in her videos made two of the respondents think that she was a poor performer, while the third respondent liked what she saw because she was interested in what Ulrica Messing said.</p> / <p>Syftet med uppsatsen var att se vilken uppfattning webbplatsbesökare kan ha när de ser fyra videofilmer som finns på regeringskansliets webbplats. En videofilm innehåller en intervju med Lena Hallengren, ungdomsminister i regeringen, och i de övriga tre talar Ulrica Messing, infrastrukturminister, om de politikområden hon är ansvarig för. </p><p>De uppfattningar som undersöktes var de som handlar om filmernas presentationsform, ministrarnas framträdanden, filmernas förmåga att skapa och upprätthålla intresse hos webbplatsbesökarna, och besökarnas beteenden och förhållningssätt vid kontakten med webbplatsen. Undersökningen utfördes med Stimulated Recall-metoden, där respondenternas minne av vad de tänkte när de besökte webbplatsen och såg filmerna samlades in, tillsammans med en intervju där de tolkade vad de hade sett.</p><p>Resultatanalysen baserades på Marshall McLuhans, Jay D. Bolter & Richard Grusins, och Jacob Nielsens teorier, som innehåller idéer om hur nya medier införlivar gamla medier, och hur Internetanvändare uppfattar och beter sig i kontakten med Internet.</p><p>Slutsatsen var att respondenterna hade ett lågt intresse för Lena Hallengrens film, eftersom var för lång och gjorde dem passiva. Ulrica Messings framträdande i sina filmer gjorde att två av respondenterna tyckte att hon var dålig i sitt framträdande, medan den tredje respondenten gillade det hon såg eftersom hon var intresserad av det som Ulrica Messing sa.</p>

This thesis presents the analysis of artistic techniques of paintings from the Precisionist movement and the implementation of the results of the analysis in the creation of three new works of art using digital media. Artists working in digital media express features of pre-digital artistic movements with varying degrees of adherence to principles, intentions, and awareness. This thesis seeks to create a bridge between the recognition of common features of Precisionist works and the expression of those elements in new works through the use of a system of analysis, interpretation, and translation. One outcome of this thesis is the description of a methodology for interpretation and translation that can be applied to other art movements. The Precisionist period within the Modern Art movement has both a historical importance in the world of art and a thematic relevance to popular uses of digital media ? specifically the representation of meaning and mood derived from industrial settings. Its influences can be traced from cubist, futurist, and constructivist art, as well as influencing the development of surrealism. It is considered the first solely American movement within Modern Art. Charles Sheeler's work plays a key role in the visual analysis portion of this research. Sheeler's work offers examples for applying 2D precisionist artistic style as aesthetic inspiration in creating a three-part production of 3D digital and video work. Work from precisionist artists Charles Demuth and Edmund Lewandowski also contribute some unique artistic characteristics considered during the analytical portion of this study. The new artistic works proposed include: (1) a linear, live-action short video with post-production manipulation; (2) a linear, 3D animated work; and (3) a non-linear, interactive 3D game environment.
