Portveb.com : um site para programadores e webdesigners

As exigências da sociedade atual obrigam a mudanças tecnológicas cada vez mais rápidas e constantes para satisfazer as necessidades empresariais, especialmente no que concerne à transmissão de informações de forma cada vez mais rápidas, mas sempre mantendo um elevado padrão de qualidade de conteúdos, bem como níveis de segurança elevados para impedir que os mesmos sejam corrompidos. Desde o aparecimento da Internet que a informação circula de forma cada vez mais veloz, em maiores quantidades e alcança cada vez mais pessoas. No entanto, nem todas as pessoas têm acesso a conteúdos de qualidade, sendo nesse ponto que o desenvolvimento do presente trabalho terá importância na respectiva área. O portveb.com é um website que pretende colmatar uma carência de conteúdos de qualidade para especialistas web designers, programadores e optimizadores de motores de busca. A importância do trabalho desenvolvido deve-se à escassez de websites da referida temática, sendo uma oportunidade para explorar a utilização de soluções técnicas como o Bootstrap, HTML, CSS, Javacript, PHP, MYSQL e desenvolver um website cuja funcionalidade não esteja só restrita a computadores pessoais, mas também a plataformas móveis. O desenvolvimento do website portveb.com demonstrou que a utilização das soluções técnicas já referidas foram a melhor opção do que concerne à obtenção de resultados, por assentar em plataformas onde não foi necessário elaborar um design de raíz, sendo que a interacção com bases de dados como PHP e MySQL tornaram o website mais dinâmico. A realização deste trabalho possibilitou ainda a descoberta de potencialidades do website para soluções técnicas futuras que se destinam a aumentar a partilha de conhecimento entre os utilizadores de forma mais prática e eficiente.

Learning Activities with Semantic. Hypermedia in Higher Education

The increasing use of information and communication technologies (ICT) in diverse professional and personal contexts calls for new knowledge, and a set of abilities, competences and attitudes, for an active and participative citizenship. In this context it is acknowledged that universities have an important role innovating in the educational use of digital media to promote an inclusive digital literacy. The educational potential of digital technologies and resources has been recognized by both researchers and practitioners. Multiple pedagogical models and research approaches have already contributed to put in evidence the importance of adapting instructional and learning practices and processes to concrete contexts and educational goals. Still, academic and scientific communities believe further investments in ICT research is needed in higher education. This study focuses on educational models that may contribute to support digital technology uses, where these can have cognitive and educational relevance when compared to analogical technologies. A teaching and learning model, centered in the active role of the students in the exploration, production, presentation and discussion of interactive multimedia materials, was developed and applied using the internet and exploring emergent semantic hypermedia formats. The research approach focused on the definition of design principles for developing class activities that were applied in three different iterations in undergraduate courses from two institutions, namely the University of Texas at Austin, USA and the University of Lisbon, Portugal. The analysis of this study made possible to evaluate the potential and efficacy of the model proposed and the authoring tool chosen in the support of metacognitive skills and attitudes related to information structuring and management, storytelling and communication, using computers and the internet.

Progressivity in the Portuguese personal income tax system

This Work Project analyzes the evolution of the Portuguese personal income tax system’s progressivity over the period of 2005 through 2013. It presents the first computation of cardinal progressivity measures using administrative tax data for Portugal. We compute several progressivity indices and find that progressivity has had very modest variations from 2005 to 2012, whilst from 2012 to 2013 there has been a relatively stronger decrease, excluding the impact of the income tax surcharge of the years 2012 and 2013. When this latter is included, progressivity of 2012 and 2013 decreases considerably. Analyzing the effective average tax rates of the top income percentiles in the income scale, we find that these rates have increased over the period 2010–2013, suggesting that an analysis of effective tax rates is insufficient to assess progressivity in the whole tax scheme.
