Abstract
The society and technologies evolution has resulted in a trend towards a growing amount of data stored by organizations and of the needs inherent to the analysis of that same data, in order to obtain information and knowledge generation. Based on this assumption it became critical to use new and more efficient technologies for processing that data in order to be able to get quality information in a timely manner. In order to meet the previously identified needs, various types of systems have emerged, whose features incorporate data processing functions and obtaining information for supporting decision-making processes. Examples of such systems are the DSS and the use of BI architectures. Given that currently many of the organizations services are supported by the existent IT infrastructure, it is necessary that these are suitable for the supporting the proper functioning of the available services. Assuming the previous concerns, the team inherent to this article assumed as very important to conceptualise a decision support system to address this adequate dimensioning of a University IT infrastructure. In order to achieve this goal, the Information and Communications Services (SIC) of the University of Tras-os-Montes e Alto Douro (UTAD) were used. Through the implementation of this decision support system, the SIC/UTAD improved their ability to make more informed and conscious decisions, thus optimizing and control more effectively the UTAD IT infrastructure.

Abstract
The current operator displays of Distributed Control Systems (DCS) are designed for 2D environments. This limits the full awareness situation of the industrial process, since it is distributed across multiple operator displays and requires the operator to navigate among them. This inspired the idea of creating a single operator display. Through an accurate and systematic literature review and by following the guidelines of design science methodology, it was possible to achieve a set of indicators and artefacts that corresponded to the defined goals. By developing a 2.5D/3D DCS interface application, the authors aimed at creating a way of allowing a full view of the entire manufacturing process, thus increasing the amount and the quality of information that is given to the operator and preventing unnecessary operation navigation between displays.

Abstract
By understanding the need for a social, collaborative and participative learning process, an analysis to the existent learning and pedagogical models was made in order to identify the existence of a basis for the development of an e-learning course implemented over a social network site. As a complement, a systematic literature review on social media adoption and use was made, particularly focusing the adoption for educational purposes and aiming at achieving the set of variables which might impact the implementation of s-learning activities. The combination of these activities resulted in the presentation of a new learning assessment model designed to be applied over e-learning courses implemented on social media. With this in mind, a description on the referred assessment model is presented, thus considering the need for a comprehensive characterization of the inherent assessment process and inherent activities and technologies. Through the execution of the research and pedagogical activities performed in the scope of the present project it was also possible to acknowledge that learning activities performed over social networks sites are a solution for improving student's willingness and commitment towards studying and learning.

Abstract
In recent years the agri-food sector has suffered a series of changes that lead to a driving need for an inclusion of ICT and Information Systems in their production and business processes. One of the agri-food sector entities that has introduced a complex set of technologies and IS in their processes was the mushrooms farms, mainly due to the urging need to control all the variables inherent to the mushroom but also to the surrounding environment. With this paper we aim to present a proposal for an amplified sensing system, composed by a set of wireless sensing nodes with the ability to control environmental indicators, which could act as a complement to a process control system. The Sousacamp Group was used, as case study, to not only identify the environmental indicators that needed to be sensed but also to test an initial version of the proposed system.

Abstract
The current level of technological evolution and the mass use of social networks sites (SNS), both by individual users and by organizations, brings to light a window of opportunity for the use of these technologies in educational activities. By analysing the existing scientific literature that focus on the adoption of SNS both at individual and organizational level, we were able to identify a gap with regard to the use of these technologies for educational purposes, making room to the need of creating a global perspective on the phenomenon through a systematic literature review. In this article we present a global characterization on the adoption of SNS for educational activities, and for that we addressed not only the perspective of educational institutions, but also the perspective of both students and teachers. Some final thoughts on future work are also presented in the final section of the article.

Abstract
The agri-food organizations evolution, and its inherent need for well supported decision making, has led to an increase on the integration of IT/IS into their business and operational processes. With this in mind, an analysis was performed to the use of systems designed to support business decisions, thus allowing to acknowledge that there was none that answered to the needs inherent to organization from the mushroom production sector. This led to the definition and implementation of a DSS system, with the necessary features and qualities, which would help the mentioned activity sector needs. This DSS was designed and tested in a real environment through the implementation of a case study within a eatable mushrooms production company named "Sousacamp Group". With the implementation of the proposed DSS, the referred business group has reported an increased in their performance levels and decision making accuracy.
