Introdução: A etiologia da otite média com efusão ainda não está completamente estabelecida, mas agentes infecciosos podem contribuir para sua patogênese. Demonstrou-se que a reação em cadeia da polimerase (PCR) é superior ao exame cultural para detectar espécies bacterianas. O conhecimento sobre a epidemiologia bacteriana da otite média com efusão em áreas geográficas distintas é essencial para a implementação de tratamentos racionais, quando necessários. Objetivos: Determinar a prevalência do Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis e Alloiococcus otitidis nas efusões de orelha média de crianças com otite média recorrente e otite média com efusão crônica que foram submetidas à miringotomia, comparar os resultados obtidos por cultura e PCR, comparar os achados bacteriológicos em crianças menores e maiores de dois anos e determinar o perfil de resistência à penicilina dos germes isolados. Métodos: Analisaram-se 128 amostras de efusões de orelha média de 75 crianças entre 11 meses e 9 anos e 4 meses de idade (média = 34,7 meses). Pacientes com otite média recorrente tinham efusão documentada por ≥ 6 semanas e aqueles com otite média com efusão crônica, por ≥3 meses. Os pacientes não tinham sinais de otite média aguda ou infecção do trato respiratório e não estavam sob antibioticoterapia no momento do procedimento. A aspiração do material foi realizada por timpanocentese...

The traditional field of journalism has been facing major challenges in recent years, either because new actors have entered that field (professional journalists actually lost the monopoly of searching, gathering, editing and diffusing news in the public sphere), or because the old actors are increasingly asked to play new roles. The social demand for more public participation in the process of handling news and information, added to the fabulous possibilities of communication brought by the digital techniques and by the Internet, gave birth to a big diversity of new media and of new forms of dealing with journalism and news. ‘Citizen journalism’, ‘participatory journalism’, ‘user-generated content’, ‘crowdsourcing’, ‘weblogs’, etc., are expressions rather common nowadays, all of them somehow calling the attention to the fact that journalism-as-a-professional-work seems to coexist more and more with various forms of journalism-as-a-civic-activity, performed by very different people, under very different conditions and with very different levels of involvement and expertise. As a consequence, questions are being raised about the ethical implications of this new scenario, both in what regards the activity of professional journalists in new (on-line) media and the active commitment of ‘laypersons’ in the process of handling and diffusing public information. In this paper we will try to analyze and to discuss these questions...

Background: Social media has the potential to accelerate the pace of biomedical research through online collaboration, discussions, and faster sharing of information. Focused web-based scientific social collaboratories such as the Alzheimer Research Forum have been successful in engaging scientists in open discussions of the latest research and identifying gaps in knowledge. However, until recently, tools to rapidly create such communities and provide high-bandwidth information exchange between collaboratories in related fields did not exist. Methods: We have addressed this need by constructing a reusable framework to build online biomedical communities, based on Drupal, an open-source content management system. The framework incorporates elements of Semantic Web technology combined with social media. Here we present, as an exemplar of a web community built on our framework, the Pain Research Forum (PRF) (http://painresearchforum.org). PRF is a community of chronic pain researchers, established with the goal of fostering collaboration and communication among pain researchers. Results: Launched in 2011, PRF has over 1300 registered members with permission to submit content. It currently hosts over 150 topical news articles on research; more than 30 active or archived forum discussions and journal club features; a webinar series; an editor-curated weekly updated listing of relevant papers; and several other resources for the pain research community.

Responsive media are media that can sense and react intelligently to factors like presentation conditions or equipment, audience identity or profile, direct interaction, history or anticipation of involvement, and so on. The emergence of modern computational devices and communication networks, with their power to manipulate media signals and objects, has spurred the development of new forms of responsive media. But a lack of a broad framework for understanding the characteristics of and motivations for these media has resulted in computer-based design tools that do not mirror the character of our projects and working practices and, in turn, compromise our ability to communicate effectively with these media. This research strives to build such a framework and use it as a foundation for a suite of three new tools that better reflect the multi-layered, multi-sensory, and multi-person nature of responsive media. Aiming to rethink the principles underlying one of the most primary building blocks in the design process, the centerpiece of this suite, Isis, is a new programming language tailored to serve as a basis for responsive media.; (cont.) The second tool, Cabbage, is an experiment in employing a purist form of case-based reasoning in a system for creating responsive graphical layouts. Lastly...

Distributed sensor networks offer many new capabilities for monitoring environments with applicability to medical, industrial, military, anthropological, and experiential fields. By making such systems mobile, we increase the application-space for the distributed sensor network mainly by providing dynamic context-dependent deployment, continual relocatabililty, automatic node recovery, and a larger area of coverage. In existing models, the addition of actuation to sensor network nodes has exacerbated three of the main problems with these types of systems: power usage, node size, and node complexity. This work proposes a solution to these problems in the form of parasitically actuated nodes that gain their mobility and local navigational intelligence by selectively engaging and disengaging from mobile hosts in their environment. This body of work evaluates parasitically actuated sensor networks as a solution to these problems through extensive software simulation and by designing, implementing, and demonstrating a parasitically mobile sensor network.; by Matthew Joel Laibowitz.; Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2004.; Includes bibliographical references (p. 213-216).

Mobile and wearable interfaces try to integrate digital information into our everyday experiences but usually require more attention than is appropriate and often fail to do so in a natural and socially acceptable way. In this thesis we present "ReachMedia," a system for seamlessly providing just-in-time information for everyday objects. The system is built around a wireless wristband that detects objects that the user is interacting with and allows the use of gestures for interaction. Thus enables hands-and-eyes-free interfacing with relevant information using a unique combination of audio output and gestural input, allowing for socially acceptable, on-the-move interaction. We demonstrate that such an interaction is more natural to the user than existing mobile interfaces.; by Assaf Feldman.; Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2005.; Includes bibliographical references (p. 66-67).

Whenever we use computers to interact with media, our experience is that of direct control, and the goal of our interactions is either artifact-production (the editor paradigm) or passive exploration (the browser paradigm). This thesis proposes an alternative: a model of media interaction based on the ideas of non-idiomatic improvisation that encourages active exploration of media and its structures. We argue that in order to facilitate this kind of exploration, (1) computational tools must actively participate in the creative process and (2) the interaction framework must allow structural exploration of media. This leads to our main claim: improvisation should be considered a valid and appropriate paradigm for media interaction. To this extent, we present a Cognitive Model of Improvisational action (CMIA) that integrates element-centric and process-centric (structural) modes of control into a single framework for media exploration. This model allows participants to switch their attention between compositional elements and structural processes.; (cont.) The model is argued to be particularly powerful in leading us to novel spaces for media creation and consumption. We follow by presenting the Emonic Environment (Implementation), an interactive system built on the principles of CMIA. We conclude by describing two studies (Scenarios a Experiments) that analyze the ways in which Emonic Environment affects how people interact and think about their interactions with digital media. These studies illustrate the potential of CMIA as a paradigm for interaction between humans and machines.; by Paul Nemirovsky.; Thesis (Ph. D.)--Massachusetts Institute of Technology...

This work examines how images of disability are used to frame cultural narratives regarding technology. As advances in biotechnology ensure that more people will be living with technological prosthetics against and beneath their skin, there is an increasing importance in examining how such bodies challenge traditional cultural attitudes regarding identity and non-normative bodies. This work uses a cultural studies approach to explore the intersections between disability and technology. Additionally, memoir is often included to illustrate some of the complexities regarding how experiences with disability and technological prosthetics can influence aspects of identity. Like disability, technology is often framed in gothic terms of lack or excess, and thus a discussion of the "techno-gothic" also features in this work. Furthermore, such a discussion is also relevant to seemingly unrelated modes of characterizing the other, such as the archetype of the cyborg, the queer body, or the formation of non-traditional social groups, even to images of the city as urban ruin.; (cont.) This work demonstrates that, while images of disability rarely inform us about the everyday experience of disability, they can inform us about how technology frames non-normative bodies as either "less than" or "more than" human...

As digital entertainment applications evolve, there is a need for new kinds of platforms that can support sociable media interactions for everyday consumers. This thesis demonstrates an extensible method and sensing framework for real-time tracking of multiple objects on an interactive table with an embedded display. This tabletop platform can support many different applications, and is designed to overcome the commercial obstacles of previous single purpose systems. The approach is supported through the design and implementation of an acoustic-based sensing system that provides a means for managing large numbers of objects and applications across multiple platform instances. The design requires precise and dynamic positioning of multiple objects in order to enable real-time multi-user interactions with media applications. Technical analysis shows the approach l:o be robust, scalable to various sizes, and accurate to a within a few millimeters of tolerance. A qualitative user evaluation of the table within a real-world setting illustrates its usability in the consumer entertainment space for digital media browsing and game play. Our observations revealed different ways of mapping physical interaction objects to the media space, as either generic controls or fixed function devices...

Informal exchanges between friends, family and acquaintances play a crucial role in the dissemination of news and opinion. These casual interactions are embedded in a network of communication that spans our society, allowing information to spread from any one person to another via some set of intermediary ties. Weblogs have recently emerged as a part of our media ecology and incidentally engender this process of media contagion; because weblog authors are tied by social networks of readership, contagious media events happen frequently, and in a form that is immediately measurable. The generally accepted notion of media diffusion is that it occurs through two channels: externally, as applied by a constant force such as the mass media, and internally through socio-structural means. Sitting between our traditional notions of mass media and the public, weblogs problematize this classical theory of mass media influence. This thesis aims to elucidate the role of weblogs in media contagion through a sociological study of this community in two parts: First, I will address the issues of modeling the social structure of weblogs as observed through their readership network, and the various media events that occur therein.; (cont.) Using a large weblog corpus collected over a one-month period...

Thesis explores the broad appeal of narratives with adolescent protagonists across a variety of media, including literature, film, and video games. An analysis of key texts within their historical contexts reveals affinities between disparate genres and strong connections between fiction and the discourse of adolescence in psychology, anthropology, and sociology. Adolescence narratives illuminate both the transgressive boundaries of a given culture and the normative center, and make explicit what is usually considered natural or implicit. To discover the roots of contemporary adolescence narratives, prototypes for the picaresque novel, the school story, and the Bildungsroman are examined, and each are shown to contain narrative conventions that survive in recent works. A contemporary case study looks at the trilogy of female coming of age films by Sofia Coppola to show how they embody the ambiguities and contradictions of third wave feminism. Finally, the author explores the affinity between video games and adolescence, the implications of translating literary genres into an interactive medium, and uses examples from both science fiction literature and recent games to theorize how games might better address the themes of adolescence in both story and play mechanics.; by Neal A.

O presente trabalho visa, em primeiro lugar, analisar a nova conceção e forma de atuação do terrorismo, numa segunda fase, analisar os media, os tradicionais e os novos e, finalmente, caracterizar a ligação entre os media e o terrorismo para concluirmos se as escolhas dos timings e da tipologia das próprias ações por parte das organizações terroristas, levam em conta a mediatização que os media lhes proporcionam. Da mesma forma, visa analisar como os media sociais, para além de servirem os interesses do terrorismo, podem ser utilizados como um catalisador ou “acelerador” de conflitos, sendo disso exemplo o fenómeno da Primavera Árabe. Neste contexto, a questão central que orienta este trabalho e à qual pretendemos dar resposta é a seguinte: “Qual o impacto social da instrumentalização dos media?”, iremos fazê-lo de acordo com a Metodologia de Investigação Científica, seguindo o método hipotético. Após uma breve introdução iremos abordar a questão do terrorismo, apresentando o conceito que será utilizado e, seguidamente, apresentamos um enquadramento histórico-científico da evolução do terrorismo no mundo, nas últimas décadas. Seguidamente, desenvolveremos o tema dos media, primeiro com os media tradicionais...

This research is intended to understand the effects of the Articulation Policy between upper secondary and higher education in Bogota. The study approached several perspectives about the process of decision makers in the City Education Office, and those of the Articulation Coordinators in the higher education institutions and in the schools. In addition to that, the project developed three case studies in order to understand the implementation process and its effects on students. Based on the findings, we determined that this policy was irrational and confused the problem of lack of identity of the upper secondary education with the scarce access to higher education. Likewise, the Articulation has promoted different cooperative and conflictive interactions at schools, and a training of the students for the social experience in higher education. However, it has not achieved an increase in higher education opportunities for these students.; Esta investigación tiene por objetivo entender los efectos de la política de Articulación entre la educación media y superior en Bogotá. Para ello, se reconstruyeron distintas perspectivas del proceso de funcionarios de la secretaría de educación, y de coordinadores de Articulación de instituciones de educación superior y colegios oficiales; posteriormente se desarrollaron tres estudios de caso para identificar lo que sucede en la implementación del programa y los efectos en los estudiantes. Los hallazgos permiten argumentar que esta política no se constituyó de forma necesariamente racional...

An audience's satisfaction with an entertainment product is dependent on how well their expectations are fulfilled. This study delves into the implicit contract that is formed between the purveyor of an entertainment property and their audience, as well as the consequences of frustrating audience expectations. Building on this model of the implicit contract, the creation of expectations through marketing, character and world development, and the invocation of genre discourses are examined through the lens of the television shows House M.D. and Veronica Mars. The issues surrounding the dynamic equilibrium between novelty and stability in serial entertainment and entertainment franchises brought up by these initial case studies are examined in further detail through the collectible card game Magic: the Gathering, and the complexity of the interactions between different types of expectations are demonstrated via a study of the superhero comics serials 52 and Civil War.; by Alexander Chance Austin.; Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Comparative Media Studies, 2007.; Includes bibliographical references (p. 131-132).

Introduction: Rehoboth, the name of my hometown in southern Massachusetts, comes from the Hebrew work for "crossroads." Indeed there's not much in this rural town besides Route 44 and Route 118, with smatterings of horse farms and single-family homes. These two blue highways intersect at the town's only stoplight. A sign stands at this intersection at the center of town, in front of the Cumberland Farms convenience store, across the street from the new Dunkin Donuts. It reads: Rehoboth, MA: Birthplace of Public Education in North America. I'm a product of these schools, but in this thesis I explore the road not often traveled in education: unschooling, a type of homeschooling with unstructured, child-directed learning. Through an examination of the attitudes, beliefs and practices related to media and technology in the unschooling subculture, I come to a definition of participatory media.; by Vanessa Bertozzi.; Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Comparative Media Studies, 2006.; Includes bibliographical references (leaves 199-206).

Life is filled with stories. Modern technologies enable us to document and share life events with various kinds of media, such as photos, videos, etc. But people still find it time-consuming to select and arrange media fragments to create coherent and engaging narratives. This thesis proposes a novel storytelling system called Storied Navigation, which lets users assemble a sequence of video clips based on their roles in telling a story, rather than solely by explicit start and end times. Storied Navigation uses textual annotations expressed in unconstrained natural language, using parsing and Commonsense reasoning to deduce possible connections between the narrative intent of the storyteller, and descriptions of events and characters in the video. It helps users increase their familiarity with a documentary video corpus. It helps them develop story threads by prompting them with recommendations of alternatives as well as possible continuations for each selected video clip. We view it as a promising first step towards transforming today's fragmented media production experience into an enjoyable, integrated storytelling activity.; Edward Yu-Te Chen.; Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning...

The article examines the impact of the economic crisis in Europe on media quality and advocates that although the crisis has jeopardized communication and education, and created serious social and political problems, it promotes a new attitude towards the media which can be considered as a new awareness towards it. A new state of affairs is emerging in which media literacy is needed and its promotion is more important for individuals as well as the public at large. This demand for media literacy requires a new policy and new initiatives. Media education, the promotion of the conditions that foster media literacy and civic participation become the main areas of this movement. The article examines research projects and other initiatives aimed at developing media literacy throughout Europe. It highlights the EMEDUS, FilmEd and DINAMIC projects.

This is a position paper on the capacity for media and information education in the UK in 2014 to facilitate media, digital and information literacy as defined by the European Commission (EC) and on the relationship between UK media/information education, regulation and law. Because the UK has a long tradition of media education within the formal curriculum (schools and colleges), the premise of this report is that the most tangible evidence of media literacy education is to be found in the teaching of Media Studies at GCSE and A-level and in higher education. Therefore the most substantive section of the report is analysis of the extent to which achievement in Media Studies can be mapped against the EC objectives for media literacy. For this purpose, media education in the mainstream curriculum is measured for its capacity to develop media literacy against a pragmatic working model derived from publications from the EC, COST/ANR, UNESCO and the UK regulator, Ofcom. Information education is currently a distinct category from media education in the UK, with a mandate for entitlement (in the case of e-safety) but without formal qualifications or assessment. The report demonstrates that the composite model of media literacy is too broad in scope and ambition for mainstream education to ‘deliver’. The model derived for this analysis...
