Multimodal Literacy as a form of Communication : What is the state of the students at Dalarna University multimodal literacy?

Literacy is an invaluable asset to have, and has allowed for communication, documentation and the spreading of ideas since the beginning of the written language. With technological advancements, and new possibilities to communicate, it is important to question the degree to which people’s abilities to utilise these new methods have developed in relation to these emerging technologies. The purpose of this bachelor’s thesis is to analyse the state of students’ at Dalarna University mulitimodal literacy, as well as their experience of multimodality in their education. This has led to the two main research questions: What is the state of the students at Dalarna University multimodal literacy? And: How have the students at Dalarna University experienced multimodality in education? The paper is based on a mixed-method study that incorporates both a quantitative and qualitative aspect to it. The main thrust of the research paper is, however, based on a quantitative study that was conducted online and emailed to students via their program coordinators. The scope of the research is in audio-visual modes, i.e. audio, video and images, while textual literacy is presumed and serves as an inspiration to the study. The purpose of the study is to analyse the state of the students’ multimodal literacy and their experience of multimodality in education. The study revealed that the students at Dalarna University have most skill in image editing, while not being very literate in audio or video editing. The students seem to have had mediocre experience creating meaning through multimodality both in private use and in their respective educational institutions. The study also reveals that students prefer learning by means of video (rather than text or audio), yet are not able to create meaning (communicate) through it.

Multimodalt skrivande - förutsättningar och lärandemöjligheter : Litteraturstudie om mellanstadieelevers lärandemöjligheter vid multimodalt skrivande inom svenskämnet och förutsättningar för en multimodal skrivundervisning

Kursplanen i svenska förklarar att eleverna ska utveckla det multimodala skrivandet inom svenskämnet. Det multimodala skrivandet innebär att ord, bild och ljud kombineras och samspelar. Huvudsyftet med den här litteraturstudien har varit att undersöka hur det multimodala skrivandet inom svenskämnet för årskurs 4-6 kan se ut, vilka kompetenser och resurser som krävs för att bedriva en multimodal skrivundervisning, samt vilket slags lärande det multimodala skrivandet kan ge upphov till hos eleverna. Litteraturstudien visar att det multimodala skrivandet kan förekomma såväl analogt som digitalt. Vidare visar den att svensk forskning på området är mycket begränsad. De artiklar och avhandlingar som inkluderats i litteraturstudien visar att forskare är eniga om att lärare behöver utveckla sina kunskaper om olika teckenvärldar, såsom auditiva och visuella, för att göra elever medvetna om teckenvärldarnas meningspotential och samspel. Det multimodala skrivandet ger upphov till en form av samordnat lärande, eftersom det multimodala skrivandet är en komplex process, som kräver att eleverna får explicit undervisning om aktuell digital programvara och teckenvärldarnas meningsskapande. Multimodalt skrivande är ett vanligt inslag utanför skolan, men bör få tillträde in i skolvärlden. Det förutsätter att digitala resurser finns tillgängliga och att lärare är positivt inställda till den multimodala skrivutvecklingen.

Um Modelo de estruturação de requisitos para o método fusion

Uma definição confiável dos requisitos de um software depende diretamente da completa e correta compreensão sobre as necessidades do sistema e sua conseqüente representação de forma adequada ao processo de desenvolvimento. Uma proposta de modelagem de requisitos deve apresentar qualidades que colaborem para a compreensão mútua das necessidades entre os envolvidos no processo e que organizem os requisitos de forma a permitir o acompanhamento no desenvolvimento do software. O presente trabalho apresenta um modelo de estruturação de requisitos fundamentado em metodologias orientadas a objetivos com utilização de cenários e preceitos da Teoria da Atividade. O modelo tem sua argumentação nas premissas que cliente e usuários normalmente expressam suas necessidades através de objetivos almejados e que a ação humana deve ser analisada dentro de um contexto para que possa fazer sentido e ser compreendida. Inserido no contexto do Projeto FILM1, cujo objetivo é expandir o Método Fusion, agregando uma etapa de modelagem de requisitos, o trabalho estabeleceu a qualidade de usabilidade como motivadora da definição de um modelo de estruturação de requisitos. A usabilidade é uma qualidade que visa facilitar a utilização do modelo como uma ferramenta de representação dos requisitos de forma inteligível, atuando tanto na especificação dos requisitos como na validação dos mesmos entre os envolvidos. Os requisitos são estruturados segundo uma abordagem voltada aos clientes e usuários do sistema. O modelo definido tem por objetivo prover a construção gradual e incremental do entendimento compartilhado entre os envolvidos sobre os domínios do problema e da solução, na concepção e no desenvolvimento do software. Metodologias orientadas a objetivos, operacionalizadas através de cenários, conjugadas a princípios da atividade oferecem um suporte adequado a estruturação de requisitos provendo usabilidade ao modelo. A avaliação da aplicabilidade do modelo é realizada com a modelagem de requisitos em três estudos de casos. Em cada caso são aplicadas técnicas de elicitação no sentido da afinar a sintonia com a estrutura do modelo de requisitos. A concepção do modelo, embasada em conceitos da Teoria da Atividade, é bastante adequado às atividades de elicitação em uma abordagem voltada aos clientes e usuários.

Atividade multimodal no córtex sensorial primário de ratos.

The currently accepted model of sensory processing states that different senses are processed in parallel, and that the activity of specific cortical regions define the sensorial modality perceived by the subject. In this work we used chronic multielectrode extracellular recordings to investigate to which extent neurons in the visual and tactile primary cortices (V1 and S1) of anesthetized rats would respond to sensory modalities not traditionaly associated with these cortices. Visual stimulation yielded 87% of responsive neurons in V1, while 82% of S1 neurons responded to tactile stimulation. In the same stimulation sessions, we found 23% of V1 neurons responding to tactile stimuli and 22% of S1 neurons responding to visual stimuli. Our data supports an increasing body of evidence that indicates the existence multimodal processing in primary sensory cortices. Our data challenge the unimodal sensory processing paradigm, and suggest the need of a reinterpretation of the currently accepted model of cortical hierarchy.

Comitês de Classificadores para o Reconhecimento Multibiométrico em Dados Biométricos Revogáveis

This work discusses the application of techniques of ensembles in multimodal recognition systems development in revocable biometrics. Biometric systems are the future identification techniques and user access control and a proof of this is the constant increases of such systems in current society. However, there is still much advancement to be developed, mainly with regard to the accuracy, security and processing time of such systems. In the search for developing more efficient techniques, the multimodal systems and the use of revocable biometrics are promising, and can model many of the problems involved in traditional biometric recognition. A multimodal system is characterized by combining different techniques of biometric security and overcome many limitations, how: failures in the extraction or processing the dataset. Among the various possibilities to develop a multimodal system, the use of ensembles is a subject quite promising, motivated by performance and flexibility that they are demonstrating over the years, in its many applications. Givin emphasis in relation to safety, one of the biggest problems found is that the biometrics is permanently related with the user and the fact of cannot be changed if compromised. However, this problem has been solved by techniques known as revocable biometrics, which consists of applying a transformation on the biometric data in order to protect the unique characteristics, making its cancellation and replacement. In order to contribute to this important subject, this work compares the performance of individual classifiers methods, as well as the set of classifiers, in the context of the original data and the biometric space transformed by different functions. Another factor to be highlighted is the use of Genetic Algorithms (GA) in different parts of the systems, seeking to further maximize their eficiency. One of the motivations of this development is to evaluate the gain that maximized ensembles systems by different GA can bring to the data in the transformed space. Another relevant factor is to generate revocable systems even more eficient by combining two or more functions of transformations, demonstrating that is possible to extract information of a similar standard through applying different transformation functions. With all this, it is clear the importance of revocable biometrics, ensembles and GA in the development of more eficient biometric systems, something that is increasingly important in the present day

Granulocytic sarcoma of the small intestine with CBF beta/MYH11 fusion gene: report of an aleukaemic case and review of the literature

Granulocytic sarcomas (GS) are rare extramedullary tumours composed of immature myeloid cells. Inversion of chromosome 16 [inv(16)] is a cytogenetic marker for M4Eo subtype of acute myeloid leukaemia (AML). The possibility of an association between the development of granulocytic sarcoma of the small intestine (GSSI) and the M4Eo subtype of AML was suggested in nine previous case reports.Here we report an aleukaemic case of GSSI with inv(16) and its molecular equivalent, the CBFbeta/MYH11 fusion gene, detected by reverse transcriptase-polymerase chain reaction (RT-PCR), that after treatment with conventional AML chemotherapy followed by autologous bone marrow transplantation, achieved complete haematological and molecular remission on bone marrow examination. After chemotherapy, a thickened ileum wall positive for CBFbeta/MYH11 on tumour mass samples was still observed on computed tomography (CT) studies, raising the question of residual GS representing a reservoir of malignant cells. This case demonstrates the critical need of multidisciplinary diagnosis and follow-up of this entity combining immunopathologic, cytogenetic and molecular studies, reinforcing the potentiality of risk-adapted therapy strategies, as it is increasingly claimed for patients with overt AML.
