Abstract
O presente artigo tem como objeto os resultados dum estudo que teve por objetivo a investigação do uso dos sistemas e tecnologias de informação (STI) no turismo em espaço rural (TER) na região do Algarve. Os resultados foram obtidos através de um questionário eletrónico, direcionado a proprietários e/ou gestores de 51 unidades TER, no qual se procurou identificar o impacto dos STI nas variáveis: tomada de decisão; satisfação dos gestores quanto ao uso dos STI; qualidade do serviço de reservas de quarto; e resultados financeiros. O estudo permitiu concluir que, de uma forma geral, a utilização dos STI são uma componente importante na gestão das unidades TER e têm impactos positivos na identificação de problemas e minimização do seu tempo de resolução; na confiança depositada no sistema e linguagem utilizada no computador; na qualidade das reservas de quartos; e nos resultados financeiros por via da inovação em tecnologia e existência de rede na organização.;This article aims to present the results of a study that investigated the use of information systems and technologies (IST) in tourism in rural space (TRS) in the Algarve region. The results were obtained through an electronic questionnaire given to the owners and/or managers of fifty one units TRS, in which we tried to identify the impact of IST in the following variables: decision making, satisfaction of managers in the use of IST, quality of room reservations service, and financial results. The study concluded that, in general, the use of IST are an important component in the TRS units of management and have positive impacts in identifying problems and minimizing their time resolution, confidence in the system and language used in the computer, the quality of rooms reservations, and financial results through innovation in technology, and network existence in the organization.

Abstract
Este artigo se contextualiza no Grupo de Pesquisa Educação Digital (GPe-dU Unisinos/CNPq), vinculado à linha de pesquisa Educação, Desenvolvimento e Tecnologias, do Programa de Pós-Graduação em Educação da Unisinos e parte da problemática: Como as mídias sociais podem contribuir com o processo de formação de professores-pesquisadores em contexto de hibridismo e multimodalidade? Seu objetivo consiste em compreender e discutir os significados construídos em relação à docência para a formação do professor-pesquisador em contexto de hibridismo e multimodalidade, quando um dos espaços disponibilizados para a prática pedagógica é uma mídia social. A pesquisa, exploratória e qualitativa, é inspirada no método cartográfico e faz uso da observação; de textos e fotografia digitais; de discursos; e de acompanhamento da experiência (trilhas). Para a análise dos dados utiliza a análise textual discursiva. Os principais resultados evidenciam que as mídias sociais podem contribuir com a formação do professor-pesquisador tanto por meio da criação de grupos no âmbito das atividades acadêmicas curriculares quanto no âmbito da prática de pesquisa e da orientação. Os dados indicam que um número significativo de sujeitos continua interagindo nos grupos, mesmo após seu término, o que contribui para que se constitua enquanto uma comunidade virtual de aprendizagem e de prática, além disso, a cada novo semestre, novos sujeitos passam a integrar essa comunidade, o que enriquece as trocas, dando origem a um processo de formação continuada.

Abstract
Data centres are large energy consumers. A large portion of this power consumption is due to the control of physical parameters of the data centre (such as temperature and humidity). However, these physical parameters are tightly coupled with computations, and even more so in upcoming data centres, where the location of workloads can vary substantially due, for example, to workloads being moved in the cloud infrastructure hosted in the data centre. Therefore, managing the physical and compute infrastructure of a large data centre is an embodiment of a cyber-physical system (CPS). In this paper, we describe a data collection and distribution architecture that enables gathering physical parameters of a large data centre at a very high temporal and spatial resolution of the sensor measurements. We detail this architecture and define the structure of the underlying messaging system that is used to collect and distribute the data.

Abstract
Due to its historical nature, data warehouses require that large volumes of data need to be stored in their repositories. Some organizations are beginning to have problems to manage and analyze these huge volumes of data. This is due, in large part, to the relational databases which are the primary method of data storage in a data warehouse, and start underperforming, crumbling under the weight of the data stored. In opposition to these systems, arise the NoSQL databases that are associated with the storage of very large volumes of data inherent to the Big Data paradigm. Thus, this article focuses on the study of the feasibility and the implications of the adoption of a NoSQL database, within the data warehousing context. MongoDB was selected to represent the NoSQL systems in this investigation. In this paper will be explained the processes required to design the structure of a data warehouse and typically dimensional queries in the MongoDB system. The undertaken research culminates in the performance analysis of queries executed in a traditional data warehouse, based on the SQL Server system, and an equivalent data warehouse based on the MongoDB system.

Abstract
This article presents a work-in-progress version of a Dublin Core Application Profile (DCAP) developed to serve the Social and Solidarity Economy (SSE). Studies revealed that this community is interested in implementing both internal interoperability between their Web platforms to build a global SSE e-marketplace, and external interoperability among their Web platforms and external ones. The Dublin Core Application Profile for Social and Solidarity Economy (DCAP-SSE) serves this purpose. SSE organisations are submerged in the market economy but they have specificities not taken into account in this economy. The DCAP-SSE integrates terms from well-known metadata schemas, Resource Description Framework (RDF) vocabularies or ontologies, in order to enhance interoperability and take advantage of the benefits of the Linked Open Data ecosystem. It also integrates terms from the new essglobal RDF vocabulary which was created with the goal to respond to the SSE-specific needs. The DCAP-SSE also integrates five new Vocabulary Encoding Schemes to be used with DCAP-SSE properties. The DCAP development was based on a method for the development of application profiles (Me4MAP). We believe that this article has an educational value since it presents the idea that it is important to base DCAP developments on a method. This article shows the main results of applying such a method.
