Oportunidades e desafios das redes sociais nas perspetivas social, organizacional e política

As redes sociais podem ser entendidas como conexões entre pessoas que se traduzem em interações sociais, que podem envolver trocas de conteúdos ou de negócios. Assim, o nosso estudo teve como objetivos centrais compreender a utilização pessoal e profissional do uso das redes sociais em seis áreas de trabalho específicas (área educacional, empresarial, política, religiosa, da saúde e geral) e efetuar uma comparação entre o nível de utilização das várias redes nessas áreas. Para tal, utilizámos um protocolo contendo um questionário com uma componente demográfica e sobre as oportunidades e desafios das redes sociais. Os resultados mostram que a rede mais utilizada a nível pessoal e profissional foi o Facebook; que os homens fazem maior utilização das redes sociais enquanto as mulheres fazem uma avaliação mais positiva; a nível pessoal, os participantes mais jovens utilizaram mais as redes sociais Facebook e Youtube e os mais velhos o Google+ e o Myspace; a nível profissional os participantes com menos de 30 anos consumiram e sentiram-se mais satisfeitos com as redes sociais. Finalmente, podemos verificar que, dentro das várias áreas de estudo, foi a área de utilização de âmbito geral (sem nenhuma área profissional específica) que mais utilizou estas plataformas; e, que, dentro das áreas profissionais, foi a empresarial a que mais as utilizou

LSP communication in a digital age: the outcomes of teaching and learning in tertiary education

This paper discusses the changes brought by the communication revolution in teaching and learning in the scope of LSP. Its aim is to provide an insight on how teaching which was bi-dimensional, turned into a multidimensional system, gathering other complementary resources that have transformed, in a incredibly short time, the ways we receive share and store information, for instance as professionals, and keep in touch with our peers. The increasing rise of electronic publications, the incredible boom of social and professional networks, search engines, blogs, list servs, forums, e-mail blasts, Facebook pages, YouTube contents, Tweets and Apps, have twisted the way information is conveyed. Classes ceased to be predictable and have been empowered by digital platforms, innumerous and different data repositories (TILDE, IATE, LINGUEE, and so many other terminological data banks) that have definitely transformed the academic world in general and tertiary education in particular. There is a bulk of information to be digested by students, who are no longer passive but instead responsible and active for their academic outcomes. The question is whether they possess the tools to select only what is accurate and important for a certain subject or assignment, due to that overflow? Due to the reduction of the number of course years in most degrees, after the implementation of Bologna and the shrinking of the curricula contents, have students the possibility of developing critical thinking? Both teaching and learning rely on digital resources to improve the speed of the spreading of knowledge. But have those changes been effective to promote really communication? Furthermore, with the increasing Apps that have already been developed and will continue to appear for learning foreign languages, for translation among others, will the students feel the need of learning them once they have those Apps. These are some the questions we would like to discuss in our paper.

Del total e marketing al marketing integral : ¿fuente de ventaja competitiva?

Según Philip Kotler, considerado el padre del mercadeo, (en su libro Principles Of Marketing) la mercadotecnia es «el proceso social y administrativo por el cual los grupos e individuos satisfacen sus necesidades al crear e intercambiar bienes y servicios». La presente investigación tomará como punto de referencia para conceptualizar el marco teórico, la historia y evolución del mercadeo y sus actuales tendencias y rumbos; así como la incidencia que tiene en la planificación del área de mercadeo para las empresas que siguen este tipo de corrientes contemporáneas. Durante el desarrollo de la presente investigación se analizaran las nuevas tendencias de mercadeo basándose en la evolución y su referencia histórica. Ahora, se verá cómo el e-marketing compone una nueva estrategia para el desarrollo de ventaja competitiva entendiéndose ésta como un conjunto de atributos de una empresa que la distinguen de sus competidores. Este nuevo marketing que se quiere presentar, Total e-marketing, se compone del posicionamiento de la organización en la realidad virtual. Se utilizarán como factores claves de éxito en el posicionamiento de la organización en buscadores de internet como redes, wikipedia, google, facebook, etc.

Scalable real-time crisis mapping and analytics of social media streams for disaster management and breaking news

Real-time geoparsing of social media streams (e.g. Twitter, YouTube, Instagram, Flickr, FourSquare) is providing a new 'virtual sensor' capability to end users such as emergency response agencies (e.g. Tsunami early warning centres, Civil protection authorities) and news agencies (e.g. Deutsche Welle, BBC News). Challenges in this area include scaling up natural language processing (NLP) and information retrieval (IR) approaches to handle real-time traffic volumes, reducing false positives, creating real-time infographic displays useful for effective decision support and providing support for trust and credibility analysis using geosemantics. I will present in this seminar on-going work by the IT Innovation Centre over the last 4 years (TRIDEC and REVEAL FP7 projects) in building such systems, and highlights our research towards improving trustworthy and credible of crisis map displays and real-time analytics for trending topics and influential social networks during major news worthy events.

Deporte: política identitaria y subalternidad etnografía virtual en torno a las gestas deportivas durante la segunda vuelta de las elecciones presidenciales 2014 en Colombia

Esta investigación se ocupa del deporte moderno en el marco de la política identitaria, la identidad nacional y la subalternidad. Se examina al deporte como espacio de inclusión del actor subalterno y la lucha del mismo por su identidad. El caso de estudio se refiere a la segunda vuelta de las elecciones presidenciales en Colombia frente a dos hechos deportivos históricos: la coronación de Nairo Quintana en el Giro de Italia 2014 y el debut de la selección nacional de fútbol en la Copa Mundial de Brasil 2014. Se implementa como metodología un modelo experimental de etnografía virtual tomando como corpus de análisis 17.323 comentarios publicados por usuarios comunes en las redes sociales (Facebook y Youtube) de 5 actores implicados: Juan Manuel Santos, Óscar Iván Zuluaga, Nairo Quintana, Rigoberto Urán y la Selección Colombia de Fútbol.

Can qualitative content analysis be adapted for use by social informaticians to study social media discourse? A position paper

IS research on social media (e.g. Facebook, Twitter, blogs) has so far used user surveys or quantitative content analysis (QuantCA) research methods almost exclusively. There is considerable potential for social informatics research to use qualitative content analysis (QualCA) to explore social media discourse and its appropriation by people “in situ”. This paper presents the position that QualCA offers researchers the flexibility to identify emergent research questions and units of analysis which they may not have preconceived. This is likely to be important for IS research because of the infancy and evolving nature of social media discourse. The paper puts forward suggestions on how the QualCA research method can be adapted for this type of research.

Blogs bother me : social media, journalism and the curriculum

This paper grew out of the authors’ interest in updating the journalism curriculum at AUT (Aukland University of Technology) to better reflect the impact of online media, including social media, on the work of journalists. The challenge for journalism educators is to remain relevant in rapidly changing news and education environments. Our study suggests that while the vast majority of students have some engagement with social media, particularly social networking, and are aware that it can be a powerful tool for journalists, they are still not entirely comfortable with its techniques and they are not experimenting with social media as a production platform as much as we first thought. In short, it appears that they do not have command of professional fluency with social media tools. In response to these findings we have begun to introduce some social media tools and processes directly into the units we teach, in particular: digital story-telling techniques; the use of Twitter and location-based applications; encouraging the ethical use of Facebook etc. for sourcing stories and talent for interviews; podcasting, soundslides and video for the Web, Dreamweaver, InDesign and PHP-based content management systems. We do not see the work to date as the end-point of the changes that we know are necessary, but we are acutely aware of the limitations (structural, institutional and financial) that suggest we should continue with this small-steps approach for the foreseeable future.
