Over the last decade, significant contributions have been made to a better understanding of sustainability and education. However, very little has been researched on sustainable education in the digital society. In new digital environments, collaborative practices, hybrid contexts, distributed knowledge or shared responsibility give rise to new approaches to the relationship between education, participation and digital inclusion - central constructs of sustainable education.
In this chapter, we propose a theoretical framework to analyze the relations between online communities, participation and digital inclusion. Sustainable education is interpreted as a shared and interactive process and is associated to community development across collaborative practices. In this framework, sustainable online communities embody the change of educ...
The @rtec project – Art and Technology in the Cultural Industries – is co-financed by InterReg IIIA and its partners are the Bienal de Vila Nova de Cerveira (Biennial of Vila Nova de Cerveira), the Centro Cultural de Deputación de Ourense (Cultural Centre of the Municipal Council of Ourense), the Universities of Minho and Vigo, the Câmara Municipal de Vila Nova de Cerveira (Municipal Council of Vila Nova de Cerveira), and the Centro de Computação Gráfica (Centre of Computer Graphics). The aim of the project is to strengthen and accomplish their objective of cultural
cooperation and development, both technological and formative, in order to reduce the disparity between the border regions and the big urban centres.
The present paper is held under the Master in Multimedia Educational Communication, Open University. It Investigates the use of Moodle in a school of secondary education, detects the effects resulting from the way it is being used this feature in the teaching / learning in the classroom teaching and the reasons that lead many teachers not to use the Moodle Platform. In this study we chose a mixed methodology using two methods of data collection: Quantitative (questionnaires) and qualitative (interviews and document analysis). Our main objective was to answer the question: How is the Platform Moodle being used by the teachers of the Secondary School Leal da Câmara. We applied the questionnaire to 54 teachers who represent a convenience sample of approximately 30% of all school teachers. We interviewed 9 teachers: 3 Moodle users, 4 non-u...
In simple or multiple linear regression analysis, the F test is used to test simultaneously the significance of a set or a subset of parameters. In this assignment it is studied the behaviour of the usual F statistic to test the significance of seasonal coefficients in multiple linear regression model for time series with trend, seasonality When some of the test assumptions are violated, we have to assume that the test can be affected. Therefore, we will analyse, through a Monte Carlo simulation study, the behaviour of the F statistic, when the normality assumptions and the independence of the error term in a specific case of autocorrelation model AR(1) are violated.
The simulation study to assess the performance of the usual F test was made under several situations, bearing in mind normality deviations and considering that the errors...
For any set X and any variety V of algebras, let A = A_V(X) be the free algebra in V with set X of free generators, and let End(A) be the monoid of endomorphisms of A. We provide a general approach to the description of the automorphism group of End(A), and some subsemigroups of End(A), provided that A is 1-simple. We show that every automorphism of End(A) is a unique extension of an automorphism of the monoid of endomorphisms of rank at most 1.
A perspectiva de realização de eleições em Angola levanta a questão das actuais e futuras transições políticas num país africano que sofreu cerca de quarenta anos de conflito armado, iniciado com a luta anti-colonial e prolongado com a guerra civil após a independência.
Após o fim da guerra, com a assinatura do Memorando de Entendimento do Luena entre o MPLA e a UNITA em Abril de 2002, renovou-se a esperança de que uma nação tão rica em recursos naturais desenvolvesse finalmente um sistema político que garantisse um desenvolvimento económico sustentável e um maior bem-estar social para a sua população. De facto, a expectativa de que a paz irá permitir um grau extraordinário de investimento (externo e interno) em actividades produtivas nunca foi tão elevada. Há quem afirme que Angola pode estar à beira de um gigantesco passo em frente...

From ancient times up to the 19th century, the concept of health has developed and overcame its supernatural meaning. At first, it meant absence of disease or handicap and consequently the presence of balanced body. Therefore, to be healthy was a synonym for well-being and harmony with the surrounding environment.
More recently, a new positive dimension of health has emerged by the WHO (1947): to be healthy is a question of physical, mental and social well-being and not just the absence of illness or infirmity. This new concept is undoubtedly a step forward, since it has allowed the blossoming of more useful and effective sanitary policies as well as the perception of health as a positive status that can be promoted, looked for, cultivated and perfected.
The interest in the maintenance and improvement of health has increased the sear...
As tecnologias moveis estão a passar por um processo de massificação, assumindo-se como ferramentas a serem usadas em qualquer situação ou local. A rápida evolução deste tipo de tecnologias, irá permitir atribuir um elevado nível de mobilidade a serviços e conteúdos remotos, fazendo uso de dispositivos moveis como PDA’s ou telefones móveis. No presente artigo será apresentado um caso prático de uma aplicação móvel de valor acrescentado desenvolvida no contexto de um projecto de I&D denominado de VADE - Value Added Environments for Dynamic Support to Location-Based Services in UMTS Networks.
