Nossa Tese postula a existência de uma cibercultura ambientalista, própria do movimento ambiental, que conta com uma dinâmica comunicativa caracterizada por estratégias de discurso e mobilização específicas. O movimento ambiental, aqui representado pela organização de espectro internacional Greenpeace, soube se apropriar das ferramentas digitais, difundir a problemática em um cenário de redes sociais digitais, ciberativismo, interatividade e composição de uma esfera pública em rede, que colocamos em debate. Para entender esse panorama realizamos uma ampla discussão teórica, em permanente diálogo com nosso objeto de estudo, abrangendo a trajetória do ambientalismo e seu lugar enquanto movimento social; as tecnologias da sociabilidade, a Internet e suas mídias como espaço de resistência e controle, assinalando a cibercultura como a própria cultura contemporânea, pautada pelas influências tecnológicas. Realizamos entrevistas com voluntários, seguidores, além de responsáveis pela comunicação do Greenpeace que nos permitiram traçar as motivações da participação e confirmar que o engajamento na causa ambiental foi fortemente impulsionado pelas facilidades do ciberespaço. As estratégias discursivas foram desvendadas com as coordenadas metodológicas da Análise do Discurso, focada na identificação do ethos e das cenas de enunciação, com base em um protocolo de análise que formulamos para compreender a maneira de dizer que leva os sujeitos aderirem maciçamente ao discurso ambiental. Na primeira etapa da análise realizamos diagnóstico de perspectiva quantitativa e caráter exploratório para levantar as campanhas/temáticas principais e avaliar a repercussão dos assuntos nas redes sociais digitais e na mídia convencional. Posteriormente, selecionamos os textos das principais campanhas que passaram pela fase qualitativa, que abarcou os itens lexicais, as técnicas argumentativas e os elementos de destacabilidade, além de aspectos externos ao texto linguístico, como fotos, vídeos, cores e cenas predominantes. O discurso na cibercultura ambiental desvela o ethos do amigo, do parceiro, que oscila entre o drama e a agressividade para chamar atenção à causa. Problemas graves como denúncias ambientais são tratados com um ethos lúdico, até mesmo infantil, usando de linguagem coloquial e de códigos da cultura contemporânea desenhos animados, jogos virtuais, belos animais que cantam e dançam que para os nossos olhos revelam uma cenografia esquizofrênica, mas é justamente o que garante o êxito das campanhas.

Estudo sobre a cobertura pela mídia de assuntos relacionados à personagem Maria Féa, considerada santa não-canônica, no período de 1994 a 2004. O objetivo foi analisar as manifestações (ex-votos) atribuídas ao credo a essa personagem, a divulgação de assuntos sobre a personagem em jornal local, além de fazer um resgate histórico do caso a partir da mídia impressa local. Tanto quanto um meio de comunicação, as manifestações de religiosidade popular podem ser consideradas formas de comunicação e a divulgação destes cultos nãocanônicos (a santos ainda não canonizados) pela mídia contribui para a continuidade destes eventos. A metodologia utilizada engloba uma série de procedimentos relativos a pesquisa bibliográfica e documental, a análise de conteúdo de veículos de mídia impressa, entrevistas semi-estruturadas e observação participante. Conclui-se que a mitificação popular com relação à Maria Fea é resultado de um grupo de fatores como a divulgação pela mídia do histórico do crime, a divulgação pela comunicação oral dos feitos espetaculares atribuídos à personagem pelos devotos, e os objetos deixados como ex-votos que comprovam seu status de santa . No caso da mídia, esta abastece seu público com elementos, como textos e fotos, que validam as várias versões sobre a personagem.(AU)

Diante do grande avanço tecnológico e utilização de equipamentos e diversas ferramentas no ensino, além da conectividade a qualquer momento, é possível perceber o grande crescimento do uso das redes sociais tanto pelos alunos como pelos professores. Com este crescimento observa-se uma comunicação mais intensa entre aluno e professor fora do ambiente da sala de aula, principalmente por intermédio das redes sociais, com a comunicação eletrônica envolvendo e-mails, conversas online, trocas de arquivos, fotos, vídeos etc. Considerando essa nova realidade esta pesquisa objetivou investigar se existe um impacto dessa nova forma de comunicação na profissão docente. Nesse contexto, tendo como foco privilegiado o facebook, emergiram alguns questionamentos para análise: essa nova ferramenta auxilia na relação professor-aluno? Ela pode trazer algum impacto positivo e/ou negativo para o professor? Qual a influência do uso dessa rede social nas relações trabalhistas? Sua existência e o seu uso podem influenciar nas decisões da coordenação/direção da escola? O estudo partiu do pressuposto de que as redes sociais exercem impactos positivos e negativos, pois podem se constituir como ferramentas que auxiliam a prática pedagógica. No entanto, no que se refere às relações trabalhistas e também, às relações interpessoais, o professor pode estar vulnerável quanto às suas relações institucionais e profissionais. Fundamentada nas concepções de autores que discorrem sobre a utilização dessas redes, e sobre as características do trabalho frente às novas demandas do capital, a pesquisa de campo, do tipo exploratória, direcionou-se no sentido de identificar esses fatores por meio da análise dos dados investigados com professores que utilizam a rede social facebook. Os resultados confirmaram que há impactos de diversas naturezas no trabalho docente. Esta nova ferramenta, ao mesmo tempo em que pode auxiliar na relação professor-aluno, expõe o docente, e é utilizada, pelas instituições de ensino, como instrumento de controle e de exercício de poder que se refletem nas relações trabalhistas.

Poster section INTRODUCTION. Retrospective Analysis PURPOSE. To evaluate the morphology and location of optic disc haemorrhages (ODH) identified at diabetic retinopathy (DR) screening to establish whether particular ODH are predictive of ocular disease (e.g. glaucoma). METHODS. Retrospective analysis of 77 patients who presented with ODH at DR screening in the Birmingham and Black Country screening programme between June 2009-March 2010. Mean age was 71 years (range 39-89). Cup/disc ratio (CDR), location and morphology of the haemorrhage were recorded. The outcome of the referral and the status of the ODH were followed up a year later. RESULTS. Of the 77 referred, 34 patients were unassessed for possible glaucoma. Of the 43 patients that were assessed in the hospital eye service for glaucoma, 11 (26%) were diagnosed with glaucoma. These glaucoma patients mostly presented with flame haemorrhages (64%) and blot haemorrhages (36%). Haemorrhages tended to adjoin the margin of the OD (64%), and were more commonly flame shaped (64%). They less commonly occurred in the optic disc itself (36%), and were all blot shaped. The OD Cup/disc ratio (CDR) of the patients with glaucoma (n=11) ranged from 0.33-0.57. It is interesting to note the highest CDR was 0.68 in the 77 patients referred. 32 patients were confirmed as not having glaucoma. 24 (75%) of these patients presented with an ODH adjoining the margin, of which 20 (83%) were flame, and 4 blot (17%) shaped. Only 8 (25%) presented with an ODH in the OD, of which 6 (75%) were blot shaped. One year follow up of the 77 referred cases revealed that the ODH resolved in 45 (57%) patients while 10 (13%) still had an ODH present. 15 (21%) were still under ophthalmology hence digital retinal photos were not available for assessment. Six patients (8%) (age range 71-91 years) died within the year, and one lost to follow up. CONCLUSIONS. The results suggest that a significant number of patients with ODH have glaucoma and that the differing morphology of the haemorrhage is not a major predictor i.e. blot versus flame shaped, adjoining or in the optic disc. The cup/disc ratio did not predict glaucoma either.

Following miniaturisation of cameras and their integration into mobile devices such as smartphones combined with the intensive use of the latter, it is likely that in the near future the majority of digital images will be captured using such devices rather than using dedicated cameras. Since many users decide to keep their photos on their mobile devices, effective methods for managing these image collections are required. Common image browsers prove to be only of limited use, especially for large image sets [1].

This paper aims to reducing difference between sketches and photos by synthesizing sketches from photos, and vice versa, and then performing sketch-sketch/photo-photo recognition with subspace learning based methods. Pseudo-sketch/pseudo-photo patches are synthesized with embedded hidden Markov model. Because these patches are assembled by averaging their overlapping area in most of the local strategy based methods, which leads to blurring effect to the resulted pseudo-sketch/pseudo-photo, we integrate the patches with image quilting. Experiments are carried out to demonstrate that the proposed method is effective to produce pseudo-sketch/pseudo-photo with high quality and achieve promising recognition results. © 2009.

When people rapidly judge the truth of claims presented with or without related but nonprobative photos, the photos tend to inflate the subjective truth of those claims-a "truthiness" effect (Newman et al., 2012). For example, people more often judged the claim "Macadamia nuts are in the same evolutionary family as peaches" to be true when the claim appeared with a photo of a bowl of macadamia nuts than when it appeared alone. We report several replications of that effect and 3 qualitatively new findings: (a) in a within-subjects design, when people judged claims paired with a mix of related, unrelated, or no photos, related photos produced truthiness but unrelated photos had no significant effect relative to no photos; (b) in a mixed design, when people judged claims paired with related (or unrelated) and no photos, related photos produced truthiness and unrelated photos produced "falseness;" and © in a fully between design, when people judged claims paired with either related, unrelated, or no photos, neither truthiness nor falsiness occurred. Our results suggest that photos influence people's judgments when a discrepancy arises in the expected ease of processing, and also support a mechanism in which-against a backdrop of an expected standard-related photos help people generate pseudoevidence to support claims.

When people receive descriptions or doctored photos of events that never happened, they often come to remember those events. But if people receive both a description and a doctored photo, does the order in which they receive the information matter? We asked people to consider a description and a doctored photograph of a childhood hot air balloon ride, and we varied which medium they saw first. People who saw a description first reported more false images and memories than did people who saw a photo first, a result that fits with an anchoring account of false childhood memories. © 2010 The Psychonomic Society, Inc.

Due to the rapid growth of the number of digital media elements like image, video, audio, graphics on Internet, there is an increasing demand for effective search and retrieval techniques. Recently, many search engines have made image search as an option like Google, AlltheWeb, AltaVista, Freenet. In addition to this, Ditto, Picsearch, can search only the images on Internet. There are also other domain specific search engines available for graphics and clip art, audio, video, educational images, artwork, stock photos, science and nature [www.faganfinder.com/img]. These entire search engines are directory based. They crawls the entire Internet and index all the images in certain categories. They do not display the images in any particular order with respect to the time and context. With the availability of MPEG-7, a standard for describing multimedia content, it is now possible to store the images with its metadata in a structured format. This helps in searching and retrieving the images. The MPEG-7 standard uses XML to describe the content of multimedia information objects. These objects will have metadata information in the form of MPEG-7 or any other similar format associated with them. It can be used in different ways to search the objects. In this paper we propose a system, which can do content based image retrieval on the World Wide Web. It displays the result in user-defined order.

In recent years, the rapid spread of smartphones has led to the increasing popularity of Location-Based Social Networks (LBSNs). Although a number of research studies and articles in the press have shown the dangers of exposing personal location data, the inherent nature of LBSNs encourages users to publish information about their current location (i.e., their check-ins). The same is true for the majority of the most popular social networking websites, which offer the possibility of associating the current location of users to their posts and photos. Moreover, some LBSNs, such as Foursquare, let users tag their friends in their check-ins, thus potentially releasing location information of individuals that have no control over the published data. This raises additional privacy concerns for the management of location information in LBSNs. In this paper we propose and evaluate a series of techniques for the identification of users from their check-in data. More specifically, we first present two strategies according to which users are characterized by the spatio-temporal trajectory emerging from their check-ins over time and the frequency of visit to specific locations, respectively. In addition to these approaches, we also propose a hybrid strategy that is able to exploit both types of information. It is worth noting that these techniques can be applied to a more general class of problems where locations and social links of individuals are available in a given dataset. We evaluate our techniques by means of three real-world LBSNs datasets, demonstrating that a very limited amount of data points is sufficient to identify a user with a high degree of accuracy. For instance, we show that in some datasets we are able to classify more than 80% of the users correctly.

In this paper, we consider the task of recognizing epigraphs in images such as photos taken using mobile devices. Given a set of 17,155 photos related to 14,560 epigraphs, we used a k-NearestNeighbor approach in order to perform the recognition. The contribution of this work is in evaluating state-of-the-art visual object recognition techniques in this specific context. The experimental results conducted show that Vector of Locally Aggregated Descriptors obtained aggregating SIFT descriptors is the best choice for this task.
