Abstract
In recent years there has been a marked increase in bank fraud by SMS (Short Messaging System) and voice. One of the factors contributing to increase in cases of SMS fraud is the low cost of acquiring large volumes of messages, the reliability (the message will reach the recipient) and the fact that it does not need the Internet to reach the victim. In relation to financial fraud by voice, these can be used to persuade victims to make bank transfers to fraudulent accounts, with the promise of receiving large sums in prizes. The prevention of these types of fraud is not a trivial task, as it requires the application of appropriate techniques and methods depending on their nature. This article presents a Systematic Literature Review (SLR) from 2015 to 2020, with the aim of analyzing the state of the art on bank frauds committed by SMS or voice. The SLR allowed the identification of the most common types of bank fraud by SMS or voice, and the respective detection techniques.

Abstract
Legislation on Information and Communication Technologies (ICT) accessibility is not new and therefore there are many national and international initiatives in place, although very web-focused. We are now on the threshold of a more comprehensive approach in the field of ICT. The European Standard EN 301 549 specifies the accessibility requirements for public procurement of ICT products and services in Europe. This study focuses both on the parameter decoding and the evolution of the European standard EN 301 549, and the translation process into European Portuguese. These were some of the steps considered for the creation of ICT Accessibility Requirements Tool (FRATIC, Ferramenta de Requisitos de Acessibilidade para TIC), designed and developed within the framework of the research under which this study falls, in order to simplify the enforcement of EN 301 549 in public procurement procedures in Portugal.

Abstract
This article presents a study on web accessibility in the health sector in Portugal. For this, 253 pages were automatically analyzed, among the various health actors: public and private institutions, health subsystems, insurance companies, pharmacies, pharmacists and informational websites. Following the Web Content Accessibility Guidelines 2.1, we seek to understand the importance and potential of accessibility today, particularly in the health sector. Once the main errors have been identified, improvements and clues for future work are pointed out.

Abstract
Rural tourism has become a truly relevant economic activity, with visible impacts (social and economic) to regional and national development and overall sustainability. The sole characteristics of rural destinations make them extremely attractive to tourists that search for experiences away from the massified and more urban areas. Despite this increase in the demand, in order to remain competitive and trigger its development and ensure sustainability, rural destinations need to ensure a twofold approach, first continuously create innovative and engaging tourism experiences, and secondly implement continuously innovative marketing approaches. Hence, to fully understand the state of the art in what concerns the incorporation of innovation by rural tourism marketeers, a systematic literature review focused on that same topic has been performed, the achieved set of 66 articles has been thoroughly analysed, and multiple results of this procedure are presented.

Abstract
With the increasing use of smartphones in people's daily lives, mobile accessibility has become a key factor for them. Tourism is one of the sectors that has benefited the most from this growth but has not yet reached its full potential as accessibility has not yet been fully exploited. The main goal of this study is to assess accessibility in mobile applications for the tourism sector. Thus, 14 mobile applications were analyzed, using a manual and automatic methodology through the proposal of an evaluation model divided by quantitative and qualitative requirements, as well as the use of features such as VoiceOver and TalkBack. The results show a high overall number of errors in most quantitative requirements as well as non-compliance with most qualitative requirements. On iPhone 4, "Viseu - Guia da Cidade" was the application with the highest rating, while on Wiko GOA, it was the "JiTT.Travel Funchal" application. In turn, on iPhone 6 Plus, iPhone XR, Nokia 5.1 and OnePlus 6 devices, the best results were achieved by the "Viseu - Guia da Cidade," "JiTT.Travel Funchal" and "TUR4all" applications. Regarding the accessibility of mobile applications on different versions of the same mobile operating system, it was concluded that there are no differences in their accessibility on both operating systems (iOS and Android). Finally, regarding the accessibility of applications on smartphones with different screen sizes, there are also no differences in their accessibility.

Abstract
As information systems and technologies grow in usage in the agri-food industry, the same has happened to the relevance of Information Systems (IS) that allow for a parallel control, monitoring and management of the organizations' activities and business processes. As the literature proves, the benefits of implementing adequate and interoperable IS are very numerous and tend to represent a significant determinant regarding the organizations' overall success. Despite this, to the best of our knowledge there currently is no IS architecture designed to serve the specificities of the agri-food industry. With this study a novel information systems architecture for the agri-food sector is proposed. The artefact is composed by 12 integrated main components and a set of subcomponents aimed at supporting all the monitoring, control and management activities. In order to validate the proposed architecture a case study was implemented at a mushroom production organization. This allowed us to perceive the ability of our artefact to serve as the basis for the development of IS that address all of the organization's business and environmental needs.
