MÍDIAS SOCIAIS DIGITAIS: ESPAÇO DE RELACIONAMENTO E COMUNICAÇÃO ESTRATÉGICA

O trabalho tem como proposta avaliar a postura das organizações nas mídias sociais digitais, considerando o fato de que esses novos ambientes virtuais têm modificado drasticamente a maneira pela qual elas promovem o relacionamento com seus públicos estratégicos. O objetivo principal da pesquisa é identificar e compreender como as organizações se posicionam diante de comentários desfavoráveis nas mídias sociais digitais que possam impactar sua imagem e reputação, bem como mostrar a importância de monitorar constantemente o consumidor e dialogar com ele nos canais digitais para evitar riscos à marca. A metodologia aplicada denomina-se Estudo de Casos Múltiplos, por meio da qual analisaram-se os comentários desfavoráveis às marcas: Vivo, Tim e Oi, na página do Facebook, durante o mês de setembro de 2015. Construiu-se um protocolo de pesquisa, e realizou-se o acompanhamento dessas marcas analisando-lhes os posts e os comentários desfavoráveis coletados no período. Constatou-se, após tais procedimentos que as operadoras apresentam frequentemente dificuldades para se relacionar com os públicos nas mídias sociais digitais, o que as coloca em risco quanto à sua imagem e reputação.

La formación especializada del community manager en el ámbito del estado español: análisis y propuestas

Este trabajo de investigación se encuadra en en el campo de estudio de los nuevos perfiles profesionales surgidos de la evolución de los social media, las redes sociales en Internet y la incorporación de las entidades y empresas a la sociedad digital con fines comerciales y de comunicación. Su temática central analiza una profesión de reciente aparición y en continua evolución, marcada por la innovación de las propias redes sociales para, con posterioridad, estudiar la componente de especialización profesional. Esta segunda finalidad se ha conseguido mediante el análisis de acciones formativas de posgrado y de formación complementaria, dirigidas a universitarios que han finalizado sus estudios de grado o están en proceso de finalizarlos y buscan completar los conocimientos adquiridos, con el deseo de especializar su perfil profesional orientándolo hacia la gestión de redes sociales, para adquirir mayores capacidades de empleabilidad. Para describir estos fenómenos y en especial el ámbito de la proliferación de la oferta formativa para profesionales del social media, y de manera especial del perfil del community manager, comenzó a gestarse hace tres años esta tesis doctoral, que culmina en el frontispicio del año 2015, cuando la crisis económica parece comenzar a superarse...

The Perceived Effects of Dance for Individuals with Parkinson’s Disease and Healthy Amateurs

The objective of the present study was to compare the effects of dance participation on physical and psychological functioning as perceived by two distinct groups of dancers: dancers with Parkinson's disease (PD) and healthy amateur (HA) dancers. Dancers in the Parkinson's sample group were gathered from participants in the Dance for PD® program, while healthy amateur dancers were recruited from university dance departments and through social media. Both groups were administered measures related to affect, self-efficacy, quality of life, and which aspects of dance classes were most helpful and/or challenging. Several open-ended questions for both groups were included, along with questions specific to each group. Results of the study indicated that there was no difference between the two groups on positive affect experienced while dancing, but that HA dancers experienced higher levels of negative affect than PD dancers. HA dancers exhibited higher levels of self-efficacy, but there was no difference between the groups on perceived quality of life. Additionally, both groups identified the same two components of dance classes as the most helpful: "moving and getting some exercise" and "doing something fun." Thematic analysis of responses to open-ended questions found that, in general, HA and PD dancers identified similar factors which made dance unique from other forms of exercise. The primary differences were that HA dancers more strongly emphasized artistic and spiritual components of dance, whereas PD dancers focused on the importance of the dance instructors and tailoring movements to individuals with PD. More differences were found between the two groups with respect to the negative aspects of dance classes. Notably, PD dancers identified almost no negative aspects, while HA dancers described internal and external pressure, criticism, and competition as problematic. Future research could benefit from ensuring that both groups are administered the same standardized measures to allow for additional comparisons between groups and with normative samples.

La búsqueda es una de las actividades centrales en el mundo digital y, por tanto, uno de los elementos clave en el análisis de cibermedios, ya que una parte de sus audiencias y de sus ingresos procede de las páginas de resultados de los buscadores (SERP). En este trabajo, presentamos algunas de las herramientas de análisis de posicionamiento SEO más utilizadas con el fin de considerar su aplicación en estudios académicos sobre cibermedios. Aplicamos los nueve indicadores más importantes de estas herramientas a la página principal de cuatro cibermedios generalistas espanoles con el fin de estimar su viabilidad como indicadores alternativos al PageRank y otros indicadores de Google.

#DressCodePM & Re-Framing The Niqab: News Sources, Hashtag Activism, and Media Representation

This thesis originates from my interest in exploring how minorities are using social media to talk back to mainstream media. This study examines whether hashtags that trend on Twitter may impact how news stories related to minorities are covered in Canadian media. The Canadian Prime Minister Stephen Harper stated the niqab was “rooted in a culture that is anti-women” on 10 March 2015. The next day #DressCodePM trended in response to the PM’s niqab remarks. Using network gatekeeping theory, this study examines the types of sources quoted in the media stories published on 10 and 11 March 2015. The study’s goal is to explore whether using tweet quotes leads to the representation of a more diverse range of news sources. The study compares the types of sources quoted in stories that covered Harper’s comments without mentioning #DressCodePM versus stories that mention #DressCodePM. This study also uses Tuen A. van Dijk’s methodology of asking “who is speaking, how often and how prominently?” in order to examine whose voices have been privileged and whose voices have been marginalized in covering the niqab in Canadian media from the 1970s and until the days following the PM’s remarks. Network gatekeeping theory is applied in this study to assess whether the gated gained more power after #DressCodePM trended. The case study’s findings indicates that Caucasian male politicians were predominantly used as news sources in covering stories related to the niqab for the past 38 years in the Globe and Mail. The sourcing pattern of favouring politicians continued in Canadian print and online media on 10 March 2015 following Harper’s niqab comments. However, ordinary Canadian women, including Muslim women, were used more often than politicians as news sources in the stories about #DressCodePM that were published on 11 March 2015. The gated media users were able to gain power and attract Canadian Media’s attention by widely spreading #DressCodePM. This study draws attention to the lack of diversity of sources used in Canadian political news stories, yet this study also shows it is possible for the gated media users to amplify their voices through hashtag activism.

Selfmapping : o mapa colaborativo como medium de visualização espácio-temporal

THE MAP AS A COLLABORATIVE MEDIUM FOR SPATIO-TEMPORAL VISUALIZATION This dissertation focuses on the relationship between maps and spatio-temporal data visualization. It is divided into two components: theoretical framework and practical approach. The study begins by questioning the role of the map in today’s digital society and particularly its role in visualization, and finishes with the conceptualization and development of an interactive dot map that visualizes data from Instagram and Twitter. Nowadays, geographic information is no longer produced just by experts, but also by ordinary people that are able to participate in data creation and exchange. The Web 2.0 lies in the heart of this change, where social media represent a significant tool for producing geotagged content, allowing its users to share their location and to spatially reference their publications. Furthermore, amateur mapmaking and neogeography have benefited from the emergence of several new devices that enable the creation of digital maps that are interactive, adaptable and easily shared on the Web. This study adopts a descriptive approach calling upon the diverse aspects of the map and its evolution as a medium for visualizing geotagged data, highlighting collaborative mapping as an emerging subject area that is of mandatory future research. Relevant projects are also analyzed in order to identify trends and different approaches for visualizing social media data in its spatial context, intended to support the project’s conceptualization, development and evaluation. The created map demonstrates how spatial knowledge and perception of place are now redefined by the contributions of individuals; it also shows how that activity produces new sources of geographic information, forcing the development of new techniques and approaches that allow an adequate exploration of content and visualization methods of the contemporary map

Da neutralidade da rede ao feudalismo na rede

A internet é um ambiente quase feudal. Para acessar a internet, você tem que aceitar contratos definidos unilateralmente por sua operadora de telecomunicações. Para utilizar aplicativos e serviços online, deve aceitar os termos de uso do fornecedor de serviço. Além de definir unilateralmente as regras que governam os seus ciberespaços, as operadoras de telecomunicações e provedores de serviços também têm a possibilidade de aplica-las por meio de medidas técnicas.

Inclusão via TV digital interativa brasileira: um estudo de caso no estado do Maranhão

Este trabalho discorre sobre o processo de implantação da TV digital interativa no Brasil, tendo como estudo de caso o estado do Maranhão e foca as possibilidades de inclusão social e digital em regiões com fragilidades de prestação de serviços públicos como Previdência Social, atendimento médico, bancário e de ensino a distância. Para tanto, aborda políticas públicas que conduziram ao SBTVD Sistema Brasileiro de Televisão Digital no país. O estudo apresenta as discussões na esfera pública e privada com a participação de organizações reconhecidamente qualificadas dentro e fora do país. Mostra também o complexo processo de articulação governamental com entidades da indústria eletroeletrônica e de grupos de telecomunicações privados instalados no Brasil, bem como a resistência de radiodifusores do setor privado em adotar o modelo proposto pelo Decreto 5.820/06 que prevê distribuição e acesso gratuito da população a serviços públicos essenciais por meio da televisão aberta. As consequências refletidas na permanência do atraso e baixo desenvolvimento do estado do Maranhão abrem possibilidades de superação com os novos programas disponibilizados pela Secretaria de Inclusão Digital (SID), do Ministério das Comunicações para responder à enorme demanda que priva regiões do Brasil como o Maranhão de desenvolvimento social e inclusão digital.

On the k-anonymization of time-varying and multi-layer social graphs

The popularity of online social media platforms provides an unprecedented opportunity to study real-world complex networks of interactions. However, releasing this data to researchers and the public comes at the cost of potentially exposing private and sensitive user information. It has been shown that a naive anonymization of a network by removing the identity of the nodes is not sufficient to preserve users’ privacy. In order to deal with malicious attacks, k -anonymity solutions have been proposed to partially obfuscate topological information that can be used to infer nodes’ identity. In this paper, we study the problem of ensuring k anonymity in time-varying graphs, i.e., graphs with a structure that changes over time, and multi-layer graphs, i.e., graphs with multiple types of links. More specifically, we examine the case in which the attacker has access to the degree of the nodes. The goal is to generate a new graph where, given the degree of a node in each (temporal) layer of the graph, such a node remains indistinguishable from other k-1 nodes in the graph. In order to achieve this, we find the optimal partitioning of the graph nodes such that the cost of anonymizing the degree information within each group is minimum. We show that this reduces to a special case of a Generalized Assignment Problem, and we propose a simple yet effective algorithm to solve it. Finally, we introduce an iterated linear programming approach to enforce the realizability of the anonymized degree sequences. The efficacy of the method is assessed through an extensive set of experiments on synthetic and real-world graphs.

Privacy and the City:user identification and location semantics in location-based social networks

With the advent of GPS enabled smartphones, an increasing number of users is actively sharing their location through a variety of applications and services. Along with the continuing growth of Location-Based Social Networks (LBSNs), security experts have increasingly warned the public of the dangers of exposing sensitive information such as personal location data. Most importantly, in addition to the geographical coordinates of the user’s location, LBSNs allow easy access to an additional set of characteristics of that location, such as the venue type or popularity. In this paper, we investigate the role of location semantics in the identification of LBSN users. We simulate a scenario in which the attacker’s goal is to reveal the identity of a set of LBSN users by observing their check-in activity. We then propose to answer the following question: what are the types of venues that a malicious user has to monitor to maximize the probability of success? Conversely, when should a user decide whether to make his/her check-in to a location public or not? We perform our study on more than 1 million check-ins distributed over 17 urban regions of the United States. Our analysis shows that different types of venues display different discriminative power in terms of user identity, with most of the venues in the “Residence” category providing the highest re-identification success across the urban regions. Interestingly, we also find that users with a high entropy of their check-ins distribution are not necessarily the hardest to identify, suggesting that it is the collective behaviour of the users’ population that determines the complexity of the identification task, rather than the individual behaviour.
