Abstract
Existing literature argues that emotions have a significant impact on the majority of human activities and functions. The learning process is one of the activities on which emotions have a direct influence. Thus, understanding the manner in which emotions change the students' learning process is not only very important but it can also allow to improve the existing learning models. Currently, in the majority of situations, the teacher serves as a facilitator between the student and the learning course, and through a constant analysis of the student's behaviour, emotions and achievements, he constantly performs adjustments to the teaching process in order to meet the students' needs and goals. Thus far, in online learning environments there is no easy way for teachers to analyse students' behaviour and emotions. A possible solution to this problem can be the development of mechanisms that enable computers to automatically detect students' emotions and adapt the learning process in order to meet students' real needs. An emotional learning model was described and a software prototype was developed and tested, in order to find out whether it performs live identification of the students' emotions, by using affective computing techniques, and whether it automatically performs adjustments to their individual learning process. Through a deeper analysis and multi-disciplinary discussion of the achieved results it is possible to acknowledge that not only emotions impact students' learning, but also that an application that performs live emotion recognition and which integrates this feature with adjustable online learning environments will trigger improvements in students' learning.

Abstract
Portuguese Higher Education Institutions have more and more data that needs to be processed in order to get information and, therefore, Knowledge. In order to respond to this need, over time there have been several types of IS supported by ICT, which enables them to achieve these features and, at the same time, help with their daily activities. However, the continuous evolution of this technological component has led to a current high degree of complexity, from which the Information Systems Architectures emerged as means of increasing the effectiveness of its management and maintenance. Using the University of Tras-os-Montes e Alto Douro as a case study, the research team proposed a generic ISA that enabled it to have a transversal vision of its IS, allowing the validation of existence/need IS focused on Information Management and decision-making under a multidimensional perspective, i.e., geared towards the various organizational levels, since the Operational level to the Strategic level, taking into account the information needs associated with each player.

Abstract
Web accessibility is becoming a current topic in social and scientific discussions. With the advances in technology, a need for access to all Web resources is becoming more and more recurrent due to the several advantages that the Web brings to those with some sort of disability, allowing them accessing and integrating in society. With this document we aim to present indicators regarding the lower accessibility levels of the Portuguese teaching institutions websites. A set of background and theoretical considerations is made alongside the article, as well as the results of an accessibility evaluation made to the Portuguese secondary schools websites using a specialized software tool and according to WCAG 2.0. The present document also contains a proposal for a model that aims on improving Web accessibility Levels in Portugal by fostering the creation of relations and group activities between the actors that, in our opinion, are those with the most relevance in the Web content accessibility issue.

Abstract
Resorting to creativity technique and their use to help innovation in the area of information systems had a growing interest. In fact, the global competitiveness and the organizations ability to make effective use of information technology and to focus on innovation and creativity are recognized as being important. So, the perspective of using creativity techniques seems to be promising. In this research work we argue that is possible in all IS areas to take advantages of the use of creative processes. We give a pragmatic reasoning and examples for the introduction of creative processes in all the main IS areas.

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.

Abstract
The agri-food industry has been growing at a considerable pace over the recent years. An example of this growth is the mushroom production sector, whose specificities associated with the production process enforce a very controlled management of all the resources applied to that activity. Considering that the existing literature does not present a transverse solution to the referred activity sector, we have endured in an effort to present a technological proposal for an information system directed to the mushroom production sector. The presented proposal, composed by 13 interconnected functional blocks, is the result of a detailed analysis to the technical and functional requirements of Sousacamp Group - a leading organization from the mushroom production sector - merged with the arguments and perspectives presented by technology adoption theories.
