Data-driven insights to reduce uncertainty from disruptive events in passenger ...
Marques, L.; Moro, S.; Ramos, P.This study investigates the predictive modeling of the impact of disruptive events on passenger railway systems, using real data from the Portuguese main operator, Comboios de Portugal. We develop models using neural networks and decision trees, using key features such as the betweenness centrality indicator, railway track, time of day, and the train service group. Conclusively, these attributes significantly p...
Weaving the threads of bibliographic ontologies: Application of a reference ont...
Patrício, H.; Ramos, P.; Cordeiro, M. I.Bibliographic ontologies are crucial to make the most of networked library metadata, but they show interoperability limitations in the Semantic Web. Following a research study on the subject, this paper presents a possible solution to such limitations by means of a reference ontology (RO) intended to allow integration of different ontologies without imposing a common central one and to overcome limitations of m...
Determinants of brand love in wine experiences
Dias, Á.; Sousa, B.; Santos, V.; Ramos, P.; Madeira, A.Wine tourism provides a multisensory experience through various wine tourism activities. It also adds value to the regions and their producers by enhancing the wine knowledge and sensory experience of the visitors. This study explores the determinants of brand love in wine tourism. Using survey data from wine tourists in Portugal, a structural equation modelling was performed to test the conceptual model. An Im...
Protein-based materials as cancer in vitro models
Ramos, P.; Maia, F. Raquel; Reis, R. L.; Oliveira, Joaquim M.The extracellular matrix (ECM) plays an active role in tumor progression. Increasing evidence points out a permissive tumor microenvironment that enhances malignancy and makes drug targeting a more difficult task. Protein-based materials as a substrate for cell culture hydrogels offer the advantage of having the presence of cell-responsive sequences as opposed to synthetic polymer-based hydrogels. This is impor...
A literature review on problem models and solution approaches for managing real...
Marques, L.; Moro, S.; Ramos, P.This study presents a comprehensive review of different problem models for managing railway operations by problem-type classification. Railway terminology was used to identify the studies that encompass the existing body of knowledge. The 28 articles analyzed showed that existing studies are focused on the individual schedule components, such as rolling stock, schedules, crews, and passengers. Few studies have ...
Mapping the wine visit experience for tourist excitement and cultural experience
Santos, V. R.; Dias, Á.; Ramos, P.; Madeira, A.; Sousa, B.This study aims to examine and estimate the relationships between wine involvement, cultural experience, winescape attributes, wine excitement and sensorial attraction in two different wine tourism destinations and the antecedent role of wine involvement as the starting point that enhances the other dimensions. Survey data was analysed using structural equation modelling. Results reveal a direct relationship of...
Using profanity and negative sentiments: An analysis of ultimate fighting champ...
Tereso, D.; Moro, S.; Ramos, P.; Calapez, T.; Costa, J. M.; Ratts, T.The rise in popularity of combat sports has afforded fighters an enhanced celebrity status, especially across online platforms that provide fans the opportunity to engage with and discuss their favorite athletes. Given this growth, fighters’ behaviors, both inside and outside of the arena, can have a strong influence on fans’ consumption and social media activity. To evaluate this relationship, this study inves...
Encouraging wine storytelling in the tourist experience: A preliminary study
Santos, V. R.; Sousa, B. B.; Ramos, P.; Dias, Á.; Madeira, A.Wine tourism has long since ceased to be just a visit to wine producing regions and wineries, just to taste or buy wine. In fact, wine tourism has become more complex as a tourist product, due to the requirement of visitors to obtain a differentiated experience, composed of multiple elements Wine tourism activities consist of, above all, wine tastings and cellar, wine house and wine museum visits. Currently, an...
Diclidophora luscae (Monogenea: Diclidophoridae) in pouting, Trisopterus luscus...
Ramos, P.; Varandas, R.; Conceição, I.L.; Grade, A.; Oliveira, M.M.; Alexandre-Pires, G.; Rosa, F.Diclidophora (Monogenea) species are gill parasites with a stenoxenic specificity occurring only in Gadiformes. Epidemiological, morphological, molecular and phylogenetic studies were performed on 594 Diclidophora specimens collected from 213 Trisopterus luscus captured in the northeast Atlantic off the Portuguese coast during 2012, 2013 and 2020. Prevalence, parasite abundance and infection intensity were dete...
The influence of cultural origins of visitors when staying in the city that nev...
Moro, S.; Rita, P.; Ramos, P.; Esmerado, J.Smart tourism can benefit from Big Data to offer personalized services that better meet tourist demands. This study addresses the adaptation versus globalization debate by analyzing all reviews made about New York City (NYC) on Booking.com, a total of 115,297 reviews for 307 hotels. The collected dataset was divided into 10 cultural clusters and category of each hotel by the star rank system. Then, 5 categories...
