Abstract
As life expectancy grows and the population requirements for satisfactory health and wellness levels increases, there is a clear opportunity for the incorporation of alternative techniques and tools for promoting health and preventing disease. One of these tools, is the use of thermal water-based treatments, commonly known as thermalism, as tools to trigger patients’ overall wellness. Despite the collective assumption of the effects of thermalism, there is little to no scientific evidence of these treatments, thus impairing the potential of this activity to become more widespread in society. Thus, with this paper, we present a conceptual model for a non-invasive sensing system based on wearables that can monitor a set of patients’ biomarkers which will serve as the basis for the validation of the effects of thermalism. This system will also serve as a management and operation control tool for thermal SPA managers and technical directors. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

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.

Abstract
The application of big data analytics in all fields of research is a critical driver for the competitiveness of all countries in the modern world. Currently, governments and industry generate large amounts of data driven by record keeping, compliance, regulations, data privacy, and dynamic requirements, and thus there is a need to create better mechanisms to analyse data, and hence support organizational development, as well as providing aid to policymakers’ decision-making processes. In this context, there are emerging disruptive opportunities because of Big Data: new business models, and vertical industry segments will emerge through shared relationships with all the stakeholders, and big data analytics is a major asset to support these dynamic relationships. This book was developed with the objective of analysing some of those challenges while at the same time providing a perspective of the potential of big data analytics, and the importance that analytics have for managers and for policymakers, to help define new strategies and new public policies, respectively. The book is focused on different sectors of activity (i.e. the Health sector, Public Administration, the Education sector, among others), and on different economic dimensions (i.e. Entrepreneurship, and Innovation) and links big data analytics to different fields of research, such as artificial intelligence and other emergent technologies; which are challenging organisations, governments, and societies, with the need to face the new imperative of being prepared for the very uncertain and tremendously complex future - in which big data analytics will play a very decisive and active role.

Abstract
In this paper we delve into the health sector and explore the way vaccines might change in the near future. As new challenges emerge, health professionals are faced with the need for innovative, effective answers to many issues, such as health-threatening viruses and diseases, that grow increasingly more complex, calling for new and practical solutions. Building on this framework, we have decided to address edible vaccines - a completely innovative and simpler way to administer vaccines - not only to understand if it is viewed in a favorable light but also to find out how the knowledge regarding these vaccines can be increased. After a thorough literature review, it became clear that the information about edible vaccines is not evident and easy to access. We then decided to apply a mixed methodology in our study, based on 15 interviews, in person and by email, addressing healthcare professionals, with the intent of gathering their experience and possible knowledge about vaccines. Additionally, an online survey was created and answered by 370 concerned citizens, in order to ascertain their knowledge and receptiveness to this matter. Hereupon, we concluded that, in both samples, there was very limited knowledge about these vaccines, it becoming obvious how important it is to transmit qualified information through accessible means, such as newscasts, scientific papers and magazines, health centers and hospitals, among others. Regarding the level of acceptance by the public in general, our results show that this innovation is dependent on its correct disclosure and propagation, since it is of great advantage and benefit for society. In sum, how the relevant knowledge (including proof of effectiveness) is managed and disseminated will be key.

Abstract
The COVID-19 pandemic has had a significant impact around the world on health, economies, businesses, equality and the movement of people in the form of tourism. In this context, this paper looks at the strategy chosen by Turismo de Portugal to adapt to the crisis in a country where tourism plays an important role in supporting the local economy, having grown significantly since 2010. The chosen strategy encouraged tourists not to visit Portugal during the pandemic, a turnaround from their previous digital marketing strategy, which invited tourists to discover the country. We undertook a survey that had 170 answers, predominantly from Ecuador, Mexico, the United Kingdom and Portugal but also from several other countries in Europe and Latin America. We aimed to understand whether their strategy was successful in encouraging people to consider Portugal as a holiday destination post-COVID-19. The Can't Skip Hope campaign was created in a work-from-home environment, with the voiceover recorded on a smartphone. Previously recorded footage was re-edited. Our survey found that respondents said the video matched their views of Portugal and that 79.5% would consider Portugal as a holiday destination when they next booked a holiday. In terms of inferential statistics, we performed chi-square tests of significance on the survey data. Thus, this paper contributes to the body of work because it offers insight into marketing strategy adaptation by a local tourist board during a period of crisis.
