- Accessibility of mobile applications for tourism - is equal access a reality?Publication . Madeira, Stephane; Branco, Frederico; Gonçalves, Ramiro Manuel; Au-Yong-Oliveira, Manuel; Moreira, Fernando; Martins, JoséWith 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.
- An integrated information systems architecture for the agri‐food industryPublication . Branco, Frederico; Gonçalves, Ramiro Manuel; Moreira, Fernando; Au-Yong-Oliveira, Manuel; Martins, JoséAs information systems and technologies grow in usage in the agri-food industry, thesame has happened to the relevance of Information Systems (IS) that allow for aparallel control, monitoring and management of the organizations' activities and busi-ness processes. As the literature proves, the benefits of implementing adequate andinteroperable IS are very numerous and tend to represent a significant determinantregarding the organizations' overall success. Despite this, to the best of our knowl-edge there currently is no IS architecture designed to serve the specificities of theagri-food industry. With this study a novel information systems architecture for theagri-food sector is proposed. The artefact is composed by 12 integrated main compo-nents and a set of subcomponents aimed at supporting all the monitoring, controland management activities. In order to validate the proposed architecture a casestudy was implemented at a mushroom production organization. This allowed us toperceive the ability of our artefact to serve as the basis for the development of ISthat address all of the organization's business and environmental needs.
- The dark side of the brand and brand hate: a review and future research agendaPublication . Walter, Cícero; Vale, Vera Teixeira; Au-Yong-Oliveira, Manuel; Veloso, Cláudia M.; Sousa, Bruno MiguelThe present study aimed to analyze the current state of the art regarding brand hate with the main intention of identifying possible gaps to be explored in future studies. Brand hate can be described as a set of negative emotions on the part of consumers concerning a certain brand, whose implications involve a reduction in the profitability of companies, as well as of their market shares. From the research carried out in the Scopus andWeb of Science databases, 90 publications related to the theme were identified, of which 25 were selected and read in full. The analyzed literature points out that research on the subject has focused almost exclusively on the development of the phenomenon and its consequences from the perspective of consumer behavior. Therefore, the emphasis has been on identifying its direct antecedents, on the effects of its mediators in a set of behaviors such as complaints, negative word of mouth, protests, sponsorship reduction and assignment, brand change, and wishes for revenge, among others. Few studies have been dedicated to understanding the direct effects of brand hate on consumer behavior, its evolution over time in different industries and contexts, who its mediators are, and how the phenomenon is perceived and managed from the perspective of the companies involved in this phenomenon, providing opportunities for future research.
