Strategies to assess web resources credibility: results of a case study in primary and secondary schools from Portugal

In this paper, three approaches for the assessment of credibility in a web environment will be presented, namely the checklists model, the cognitive authority model and the contextual model. This theoretical framework was used to conduct a study about the assessment of web resources credibility among a sample of 195 students, from elementary and secondary schools in a municipality in Oporto district (Portugal). The practices that young people and children claim to use regarding the use of criteria for web resources selection will be presented. In addition, these results will be discussed and compared with the perceptions that these respondents have demonstrated for the use of criteria to establish or assess authorship, originality, or information resources structure. These results will be also discussed and compared with the perceptions that these respondents have demonstrated for the elements that make up each of these criteria.

Thinking over b‐learning strategy: the MIPO model approach

This article describes the main research results in a new methodology, in which the stages and strategies of the technology integration process are identified and described. A set of principles and recommendations are therefore presented. The MIPO model described in this paper is a result of the effort made regarding the understanding of the main success features of good practices, in the web environment, integrated in the information systems/information technology context. The initial model has been created, based on experiences and literature review. After that, it was tested in the information and technology system units at higher school and also adapted as a result of four cycles of an actionresearch work combined with a case study research. The information, concepts and procedures presented here give support to teachers and instructors, instructional designers and planning teams – anyone who wants to develop effective b‐learning instructions.

Plataforma de Dados de Saúde - Portal Institucional

O presente documento de dissertação retrata o desenvolvimento do projeto PDS-Portal Institucional cujo cerne é um sistema para recolha, armazenamento e análise de dados (plataforma de Business Intelligence). Este portal está enquadrado na área da saúde e é uma peça fundamental no sistema da Plataforma de dados da Saúde, que é constituído por quatro portais distintos. Esta plataforma tem como base um sistema totalmente centrado no utente, que agrega dados de saúde dos utentes e distribui pelos diversos intervenientes: utente, profissionais de saúde nacionais e internacionais e organizações de saúde. O objetivo principal deste projeto é o desenvolvimento do PDS-Portal Institucional, recorrendo a uma plataforma de Business Intelligence, com o intuito de potenciar os utilizadores de uma ferramenta analítica para análise de dados. Estando a informação armazenada em dois dos portais da Plataforma de dados da Saúde (PDS-Portal Utente e PDS-Portal Profissional), é necessário modular um armazém de dados que agregue a informação de ambos e, através do PDS-PI, distribua um conjunto de análises ao utilizador final. Para tal este sistema comtempla um mecanismo totalmente automatizado para extração, tratamento e carregamento de dados para o armazém central, assim como uma plataforma de BI que disponibiliza os dados armazenados sobre a forma de análises específicas. Esta plataforma permite uma evolução constante e é extremamente flexível, pois fornece um mecanismo de gestão de utilizadores e perfis, assim como capacita o utilizador de um ambiente Web para análise de dados, permitindo a partilha e acesso a partir de dispositivos móveis. Após a implementação deste sistema foi possível explorar os dados e tirar diversas conclusões que são de extrema importância tanto para a evolução da PDS como para os métodos de praticar os cuidados de saúde em Portugal. Por fim são identificados alguns pontos de melhoria do sistema atual e delineada uma perspetiva de evolução futura. É certo que a partir do momento que este projeto seja lançado para produção, novas oportunidades surgirão e o contributo dos utilizadores será útil para evoluir o sistema progressivamente.

Frameworks e Bibliotecas Javascript

This report describes a study based on a research and evaluation of platforms (JavaScript frameworks and libraries carried out under the discipline of Tese/Dissertação/Estágio in the Master Degree Computer Science - area of expertise in Arquitecturas Sistemas e Redes, in Instituto Superior de Engenharia do Porto (ISEP). The JavaScript language is increasingly present in the development of software and particularly software for the web environment. For this reason there is a need to investigate the issue, as the platforms that are emerging in the market have a very low level of maturity compared to existing, it is crucial to identify the main differences so that we can save time, labor and other costs in research and experimentation developers. This project aims to inform a range of platforms and existing JavaScript libraries on the market. For further investigation, a study of use cases used at this point in the market was held. To assist the work were used qualitative research methods through the existing content of research related to the area, and quantitative research methods. It was thus conducted a survey sent via email to fifty regular users of the language, platforms, and JavaScript libraries, linking the functional and non-functional characteristics of the platforms and existing use cases in the market, in order to realize what is the use of these tools in his professional life. This study allowed developers to access information that will be compared and evaluated in order to achieve a more precise evaluation of the various analyzed platforms. It was also made an evaluation of adaptation of the various platforms to the various use cases.

A survey of techniques and technologies for web-based real-time interactive rendering

When exploring a virtual environment, realism depends mainly on two factors: realistic images and real-time feedback (motions, behaviour etc.). In this context, photo realism and physical validity of computer generated images required by emerging applications, such as advanced e-commerce, still impose major challenges in the area of rendering research whereas the complexity of lighting phenomena further requires powerful and predictable computing if time constraints must be attained. In this technical report we address the state-of-the-art on rendering, trying to put the focus on approaches, techniques and technologies that might enable real-time interactive web-based clientserver rendering systems. The focus is on the end-systems and not the networking technologies used to interconnect client(s) and server(s).

Towards e-learning 2.0: case study of an e-learning environment

In these days the learning experience is no longer confined within the four walls of a classroom. Computers and primarily the internet have broadened this horizon by creating a way of delivering education that is known as e-learning. In the meantime, the internet, or more precisely, the Web is heading towards a new paradigm where the user is no longer just a consumer of information and becomes an active part in the communication. This two-way channel where the user takes the role of the producer of content triggered the appearance of new types of services such as Social Networks, Blogs and Wikis. To seize this second generation of communities and services, educational vendors are willing to develop e-learning systems focused on the new and emergent users needs. This paper describes the analysis and specification of an e-learning environment at our School (ESEIG) towards this new Web generation, called PEACE – Project for ESEIG Academic Environment. This new model relies on the integration of several services controlled by teachers and students such as social networks, repositories libraries, e-portfolios and e-conference sytems, intelligent tutors, recommendation systems, automatic evaluators, virtual classrooms and 3D avatars.

Personal learning environments: integration of Web 2.0 applications and content management systems

This paper presents an ongoing project that implements a platform for creating personal learning environments controlled by students, integrating Web 2.0 applications and content management systems, enabling the safe use of content created in Web 2.0 applications, allowing its publication in the infrastructure controlled by the HEI. Using this platform, students can develop their personal learning environment (PLE) integrated with the Learning Management System (LMS) of the HEI, enabling the management of their learning and, simultaneously, creating their e-portfolio with digital content developed for Course Units (CU). All this can be maintained after the student completes his academic studies, since the platform will remain accessible to students even after they leave the HEI and lose access to its infrastructure. The platform will enable the safe use of content created in Web 2.0 applications, allowing its protected publication in the infrastructure controlled by HEI, thus contributing to the adaptation of the L&T paradigm to the Bologna process.

Integração de aplicações Web 2.0 e sistemas de gestão de conteúdos em ambientes pessoais de aprendizagem

A utilização de aplicações Web 2.0 no processo ensino/aprendizagem tem vindo a intensificar-se nos últimos tempos, mais por iniciativas individuais de docentes e estudantes do que por estratégia das Instituições de Ensino. Este artigo apresenta um projecto já em curso que consiste na implementação de uma plataforma de criação de ambientes de aprendizagem controlados pelos estudantes, integrando aplicações Web 2.0 e sistemas de gestão de conteúdos. A plataforma permitirá a utilização segura de conteúdos criados em aplicações Web 2.0, no processo de avaliação, possibilitando a sua publicação na infra-estrutura controlada pela Instituição de Ensino Superior, contribuindo assim para a adequação do binómio ensino/aprendizagem ao novo paradigma implicado no processo de Bolonha.

Navegação web anónima e segura

A Web aproximou a humanidade dos seus pares a um nível nunca antes visto. Com esta facilidade veio também o cibercrime, o terrorismo e outros fenómenos característicos de uma sociedade tecnológica, plenamente informatizada e onde as fronteiras terrestres pouco importam na limitação dos agentes ativos, nocivos ou não, deste sistema. Recentemente descobriu-se que as grandes nações “vigiam” atentamente os seus cidadãos, desrespeitando qualquer limite moral e tecnológico, podendo escutar conversas telefónicas, monitorizar o envio e receção de e-mails, monitorizar o tráfego Web do cidadão através de poderosíssimos programas de monitorização e vigilância. Noutros cantos do globo, nações em tumulto ou envoltas num manto da censura perseguem os cidadãos negando-lhes o acesso à Web. Mais mundanamente, há pessoas que coagem e invadem a privacidade de conhecidos e familiares, vasculhando todos os cantos dos seus computadores e hábitos de navegação. Neste sentido, após o estudo das tecnologias que permitem a vigilância constante dos utilizadores da Web, foram analisadas soluções que permitem conceder algum anónimato e segurança no tráfego Web. Para suportar o presente estudo, foi efetuada uma análise das plataformas que permitem uma navegação anónima e segura e um estudo das tecnologias e programas com potencial de violação de privacidade e intrusão informática usados por nações de grande notoriedade. Este trabalho teve como objetivo principal analisar as tecnologias de monitorização e de vigilância informática identificando as tecnologias disponíveis, procurando encontrar potenciais soluções no sentido de investigar a possibilidade de desenvolver e disponibilizar uma ferramenta multimédia alicerçada em Linux e em LiveDVD (Sistema Operativo Linux que corre a partir do DVD sem necessidade de instalação). Foram integrados recursos no protótipo com o intuito de proporcionar ao utilizador uma forma ágil e leiga para navegar na Web de forma segura e anónima, a partir de um sistema operativo (SO) virtualizado e previamente ajustado para o âmbito anteriormente descrito. O protótipo foi testado e avaliado por um conjunto de cidadãos no sentido de aferir o seu potencial. Termina-se o documento com as conclusões e o trabalho a desenvolver futuramente.

Enhancing reflexivity and technology in translation learning: case study on the use of ePortfolio as a training environment

In this paper we describe a casestudy of an experiment on how reflexivity and technology can enhance learning, by using ePorfolios as a training environment to develop translation skills. Translation is today a multiskilled job and translators need to assure their clients a good performance and quality, both in language and in technology domains. In order to accomplish it, for the translator all the tasks and processes he develops appear as crucial, being pretranslation and posttranslation processes equally important as the translation itself, namely as far as autonomy, reflexive and critical skills are concerned. Finally, the need and relevance for collaborative tasks and networks amongst virtual translation communities, led us to the decision of implementing ePortfolios as a tool to develop the requested skills and extend the use of Internet in translation, namely in terminology management phases, for the completion of each task, by helping students in the management of the projects deadlines, improving their knowledge on the construction and management of translation resources and deepening their awareness about the concepts related to the development and usability of ePorfolios.

The prominence of social responsibility disclosure in Portuguese companies’ web pages

This study investigates Portuguese companies’ use of the Internet to communicate social responsibility information, and the factors that affect this use. It examines the characteristics of companies that influence the prominence of social responsibility information on the Internet. Firm-specific factors that explain SRD by companies operating in a European country in which capital market fund raising is not regarded to be an important source of financing are analysed. The results are interpreted through the lens of a “political economy” framework which combines stakeholder and legitimacy theories perspectives, according to which companies disclose social responsibility information to present a socially responsible image so that they can legitimise their behaviours to their stakeholder groups and influence the external perception of reputation. Results suggest that a theoretical framework combining stakeholder and legitimacy theories may provide an explanatory basis for SRD by Portuguese companies. However, this study does not provide us with enough evidence to determine that the prominence given to CSR activities by Portuguese companies in their websites is linked to relationships with their stakeholders

Accounting education in an action-based learning environment: lessons learned

In the context of the Bologna Declaration a change is taking place in the teaching/learning paradigm. From teaching-centered education, which emphasizes the acquisition and transmission of knowledge, we now speak of learning-centered education, which is more demanding for students. This paradigm promotes a continuum of lifelong learning, where the individual needs to be able to handle knowledge, to select what is appropriate for a particular context, to learn permanently and to understand how to learn in new and rapidly changing situations. One attempt to face these challenges has been the experience of ISCAP regarding the teaching/learning of accounting in the course Managerial Simulation. This paper describes the process of teaching, learning and assessment in an action-based learning environment. After a brief general framework that focuses on education objectives, we report the strengths and limitations of this teaching/learning tool. We conclude with some lessons from the implementation of the project.
