Several users regularly produce video content and make this task their main livelihood. However, such success is also drawing the attention of malicious users propagating undesired comments and videos, looking for self-promotion or disseminating malicious links which may have malwares and viruses. Since YouTube offers limited tools for blocking spam, the volume of such messages is shockingly increasing and harming users and channels owners. In addition to the problem being naturally online, comment spam filtering on YouTube is different than the traditional email spam filtering, since the messages are very short and often rife with spelling errors, slangs, symbols and abbreviations. This manuscript presents a performance evaluation of traditional online classification methods, aided by lexical normalization and semantic indexing techniques when applied to automatic filter YouTube comment spam. It was also evaluated the performance of MDLText, a promising text classification method based on the minimum description length principle. The statistical analysis of the results indicates that MDLText, Passive-Aggressive, Naïve Bayes, MDL and Online Gradient Descent obtained statistically equivalent performances. The results also indicate that the lexical normalization and semantic indexing techniques are effective to be applied to the problem. Based on the results, it is proposed and designed TubeSpam, an online tool to automatic filter undesired comments posted on YouTube. / O YouTube tem se tornado uma importante plataforma de compartilhamento de vídeos. Muitos usuários produzem regularmente conteúdo em vídeo e fazem desta tarefa seu principal meio de vida. Contudo, esse sucesso também vem despertando a atenção de usuários mal-intencionados, que propagam comentários e vídeos indesejados para se autopromoverem ou para disseminar links maliciosos que podem conter vírus e malwares. Visto que o YouTube atualmente oferece recursos limitados para bloquear spam, o volume dessas mensagens está impactando muitos usuários e proprietários de canais. Além da característica inerentemente online do problema, filtrar spam nos comentários do YouTube é uma tarefa que difere-se da tradicional filtragem de spam em emails, pois as mensagens costumam ser muito mais curtas e repletas de erros de digitação, gírias, símbolos e abreviações que podem dificultar a tarefa de classificação. Assim, nesta dissertação é apresentada a avaliação de desempenho obtido por métodos tradicionais de classificação online auxiliados por técnicas de normalização léxica e indexação semântica, quando aplicados na filtragem automática de comentários indesejados postados no YouTube. Foi avaliado também o desempenho do MDLText, um promissor método de classificação de texto baseado no princípio da descrição mais simples. A análise estatística dos resultados indica que os métodos MDLText, Passivo-Agressivo, Naïve Bayes, MDL e Gradiente Descendente Online obtiveram desempenhos equivalentes. Além disso, os resultados também indicam que o uso de técnicas de normalização léxica e indexação semântica são eficazes para atenuar os problemas de representação de texto e, consequentemente, aumentar o poder de predição dos métodos de classificação. Baseado nos resultados dos experimentos, foi proposto e desenvolvido o TubeSpam, uma ferramenta online para filtrar automaticamente comentários indesejados postados no YouTube.

This study analysed the representation of the Millennium Development Goals (MDGs) in the Mail and Guardian from 2000 to 2007. It drew on perspectives from cultural studies, the constructionist approach to representation and the sociology of news production. Through the use of the quantitative and qualitative research methods, content analysis and critical discourse analysis, this study established first, that few significant changes have occurred within the newspaper's coverage of the MDGs during this period, and second, that the people most affected by the MDGs and affiliated programmes are seriously under-represented and that the manner of representation marginalises and subordinates them.

Internal marketing and internal communication are essential tools to align em-ployees’ mindsets with the necessary tasks which bring about employee satis-faction and organisational prosperity. Electronic newsletters serve as an internal marketing communication medium which can convey the necessary information to employees regarding the organisation’s goals and objectives. They also act as a medium to build relationships with employees and encourage improved service delivery and customer-oriented employee mindsets. Employees’ willingness to make use of electronic newsletters for the purpose of disseminating organisational information is an indication of employees’ acceptance of the organisational information and use thereof in performing organisational tasks successfully as the organisation intends. The purpose of the current study was to determine employees’ acceptance of electronic newsletters, as an internal marketing communication medium, in order to disseminate organisational information which contributes to the attainment of organisational goals, objectives and success. An empirical study was conducted to determine employees’ acceptance of elec-tronic newsletters by means of an adapted technology acceptance model, self-administered, e-mail survey disseminated to employees of a higher education institution. The study followed a quantitative research approach, utilising re-gression in the analysis of the data. Based on the research results, employees do accept the electronic newsletter for the dissemination of organisational information, albeit with suggestions on how it can be better utilised in future. / Business Management / M.

Esta pesquisa trata das maneiras pelas quais a imagem pública do artista popular gaúcho Vitor Mateus Teixeira, conhecido como Teixeirinha – que morreu em 1985, depois de uma longa carreira de sucesso no Brasil e no exterior na música e no cinema – é construída, percebida e colocada em circulação. Através de uma etnografia das manifestações de seus fãs no cemitério da Santa Casa, das correspondências dos fãs, dos discursos da imprensa escrita e televisiva sobre o artista, e dos projetos de vários agentes dedicados à gestão de sua imagem pública, especialmente aqueles conduzidos por sua família, representada pela Fundação Vítor Mateus Teixeira, eu tento mostrar como a imagem de um ídolo popular pode se tornar um objeto de disputas. Além disso, argumento que a trajetória de um “herói” do povo pode, através de um viés antropológico, ser tomada como uma espécie de lente através da qual se pode colocar em evidência muitas dimensões do imaginário e da memória coletiva da sociedade brasileira. / This research is about the ways through which the public image of gaucho popular artist Vitor Mateus Teixeira, known as Teixeirinha – who passed away in 1985, after a long successful career in Brazil and abroad in the music and cinema business – is built, acknowledged and placed into circulation nowadays. Through an ethnography of his fans’ manifestations at the Santa Casa cemetery, of fan mail, of the discourse from the press about the artist, and the projects of the various agents dedicated to the management of his current image, especially the ones conducted by his family, represented by the Vitor Mateus Teixeira Foundation, and the press from Rio Grande do Sul, I try to show how this image of a popular idol can become a disputed object. Besides that, I argument that the trajectory of a popular "hero" can, through an anthropological bias, be taken as a type of lens, which is able to place in evidence many dimensions of the imaginary and of the collective memory of the Brazilian society.
