  • Analysis of oleotourism and museology: bibliometric analysis and systematic literature review
    Publication . Ferreira, Jessica; Silvério, Ana Cristina; Vaz, Márcia; Fernandes, Paula Odete
    Traditional Olive Grove represents about 80% of the awards in the National Olive Oil Competition of Portugal, substantiating the importance and relevance of the sector. The term "oleotourism" is considered as a movement that increasingly aims to know all the features, qualities, and differences in olive oil production. As a dynamic movement, this term uses museology to present and promote its products to the public and tourism. From museology articles, it wasunderstood that the museums should not be limited to the institutionally conceived idea, instead of that, it should be understood as a global science of a distinct, which encompasses the universe and society. Subsequently, the relevance of conducting qualitative research arises, studying the literature on oleotourism associated with museology and analysing their contributions and effects on tourism. After reviewing the existing databases, the SCOPUS database was selected to collect and analyse the bibliographic material. Hence, as the purpose, this study aimed to highlight the scientific publications with the most significant impact of the terms "oleotourism" and "museology", understanding their research trends. In the systematisation process, we considered the final 100 articles with the most citations published in journals between 2005 and 2021. The articles analysed were reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for the systematic literature review. For the bibliometric analysis, the Bibliometrix R program was used. As a result, from the bibliometric analysis, it was found that, as research trends, the keywords "olive oil tourism" and "museums" were highlighted, with Italy, Spain and the United Kingdom as the countries with the most citations. In addition, the journals "Sustainability", "Museum Anthropology", and "Museum Management and Curation" in the publications on these themes are highlighted. In comparison, through the systematic literature review, it was understood that the research trends focused on: the conceptualisation of oleotourism; the influence of museology on tourism; and the importance of museum education. Despite the importance of this research in helping future studies, there are some limitations on their analysis, which will be recommended to use specific databases for the themes and increase the number of articles considered.

  • Assessing the impact of working capital on free cash flow: evidence from portuguese accommodation companies
    Publication . Fernandes, António B. ; Cardim, Sofia; Ferreira, Jessica; Pinto, Lígia
    This study analyses the impact of working capital (WC) on free cash flow (FCF) for Portuguese firms operating in Division 55 (Accommodation), a sector that is a central pillar of the national tourism industry and characterised by high capital intensity and pronounced seasonality. The empirical analysis is based on an unbalanced panel dataset of 5,744 firms, corresponding to 27,689 firm-year observations for the period 2011–2023, obtained from the SABI database. A panel data model is estimated using generalised estimating equations (GEE) with firm- and year-fixed effects to examine how changes in WC and its components influence firms’ capacity to generate FCF. Twelve research hypotheses are formulated and empirically tested within a cash-flow-based valuation framework. The results show that variations in WC have a negative and statistically significant effect on FCF, indicating that increased investment in short-term operational assets constrains liquidity generation in the accommodation sector. Several components of WC are identified as significant determinants of FCF, while others do not exhibit statistically significant effects, underscoring the heterogeneous influence of short-term assets and liabilities on cash flow dynamics. The model adjustment criteria (QIC and QICC), assessed within the scope of the GEE, indicate that the estimated specification is well suited and robust, supporting the reliability of the results obtained. Although the analysis is limited to the accommodation sector, which may restrict the generalisability of the findings, the study makes an important contribution by adopting an FCF-based perspective on WC management. By focusing on liquidity generation rather than traditional profitability measures, this research enhances understanding of financial management dynamics in tourism-related firms and provides insights into firms’ strategic flexibility and capacity to invest in market-facing activities.

    Publication . Ferreira, Jessica; Scalabrini, E. C. B.; Silvério, Ana Cristina; Vaz, Márcia; Fernandes, Paula Odete
    Gastronomicdevelopmentcausedmanydestinationstofocusonfood as a central element of their tourism products. Studies highlight that tourism devel- opment in rural areas will depend on various political, economic, and environmen- tal factors, which is why tourism activities such as oleotourism and gastronomic tourism are essential. To understand the relationship between gastronomy and olive growing from a tourism perspective, this study aims to explore scientific production through a bibliometric analysis. These bibliometric analysis goals are to develop a search equation based on the terms “Gastronomy” and “Olive Oil”, to understand the topics’ development. Specifically, analysing the evolution of pro- duction and citation, it was understood that oleotourism is prominent and relevant in the database trend map. The authors with the highest relevance have worked on topics such as the effect of spice infusion in olive oil, and Italy and Spain are very relevant in this field of research.

  • Bibliometric analysis of TOP 100 most cited articles on tourism development of the last 10 years
    Publication . Ferreira, Jessica; Silvério, Ana Cristina; Fernandes, Paula Odete
    Tourism is considered a strong betting sector, not only for its ability to bring life to spaces that were once almost abandoned, but also to rethink and remake old traditions, making it an enriching tourist experience, preserving and valuing historical, cultural, and environmental resources, generating wealth and employment. Tourism development has been affected by the evolution of society and the various tourism markets. For this reason, a Bibliometric Analysis of tourism development and its components becomes essential. A thorough search of the Scopus database was conducted using “tourism development” as the search keyword. They were only considered open access articles of the last 10 years (2012–2021), accounting for a total of 1698 documents. In the progression of Bibliometric Analysis, will be used a software tool for creating maps based on network data, concretely the VOSviewer program. For this, the 100 most cited articles were stratified in descending order, and then, analyzed their relationships, as well as the most commonly used keywords. Many articles on tourism development have been published in recent 10 years. Hence, the Scopus database used has 1689 articles, 4253 authors, and 3524 organizations involved. The five countries with the most citations correspond to United Kingdom (214 documents and 3835 citations), Australia (100 documents and 2139 citations), United States (118 documents and 2018 citations), China (243 documents and 1768 citations), and Spain (203 documents and 1573 citations). The present analysis of highly cited studies can help in future studies, supporting the understanding of the trends in tourism development studies.

  • Building resilient tourism systems: the strategic role of financial sustainability in portuguese tourism firms
    Publication . Fernandes, António B. ; Ferreira, Jessica; Seidi, Fadiba; Cardim, Sofia
    This study examines the economic and financial sustainability of Portuguese tourism firms operating within Division 55 (Accommodation) and Division 56 (Food and Beverage Service Activities), using Return on Assets (ROA) as the central indicator of economic and financial sustainability to assess variations over time, across firm sizes and among regions. Drawing on a dataset of 8,735 firms and 113,559 observations from 2011 to 2023, the analysis relies on ROA due to its analytical robustness and suitability for longitudinal and cross-sectional comparison. Given the absence of normality and homogeneity of variances, robust statistical techniques were applied, namely Welch’s ANOVA and the Games-Howell post hoc test with bootstrapping, to ensure reliable inference. The findings reveal significant differences in financial sustainability over the study period, between firms of different sizes and across regions. Small firms record higher average ROA than micro, medium or large firms, while the Algarve emerges as the highest-performing region and the Autonomous Region of the Azores presents the weakest results. The study is limited by its exclusive reliance on quantitative financial indicators, without incorporating qualitative dimensions that might enrich understanding of sustainability drivers, and by the constraints posed by data non-normality. The results emphasise the need for policy measures tailored to regional characteristics and highlight the pivotal role of small firms in resilience in the tourism sector. The study adds value by providing a rigorous, longitudinal and regionally differentiated analysis of financial sustainability within the Portuguese tourism industry.

  • Evolução de indicadores económico-sociais na Guiné-Bissau
    Publication . Té, Leandro; Cardim, Sofia; Ferreira, Jessica
    A região da África Ocidental carateriza-se por um elevado padrão de riqueza natural, mas também por uma grande diversidade religiosa e cultural. É, no entanto, condicionada, com frequência, por uma elevada instabilidade política e, de forma consequente, por instabilidade governativa, fatores que impedem um desenvolvimento harmonioso dos diversos territórios que integram esta região. A República da Guiné-Bissau, território que tem uma população estimada de 1,8 milhões de habitantes, carateriza-se por ser uma economia em desenvolvimento que enfrenta desafios significativos, uma vez que o seu Produto Interno Bruto (PIB) se situa entre os mais baixos do mundo. A atividade económica do país é marcadamente rural, sendo o peso do setor primário de aproximadamente 50% do produto nacional, uma vez que tanto a agricultura como a pesca são as atividades que fornecem emprego para a maioria da população ativa, tratando-se em muitos casos, de uma agricultura de subsistência. Ainda no que respeita à agricultura, mais concretamente, às espécies cultivadas, destaca-se a predominância da castanha de caju, que representa uma parte significativa das exportações do país, gerando receita em moeda estrangeira e contribuindo para a balança comercial do país. A estrutura empresarial é marcada por uma elevada informalidade e falta de profissionalização. A criação do Centro de Formalização de Empresas no ano de 2011 tem contribuído para o estabelecimento de práticas empreendedoras, uma vez que tem prestado apoio na criação de empresas. Entre os anos de 2011 e 2022, foram constituídas através deste centro 5.710 empresas. Face ao exposto, o presente trabalho tem como objetivos fornecer uma visão integrada de diversos indicadores, entre os anos de 2018 e 2022, potenciando uma visão integrada da evolução económica e social do território. A metodologia segue um processo descritivo, uma vez que se recorreu a diversas bases de dados internacionais, para identificar a evolução de um grupo de indicadores previamente selecionados. Neste sentido, são analisados os seguintes indicadores: evolução do PIB a preços correntes, evolução do PIB per capita a preços correntes, evolução da taxa de desemprego, evolução da taxa de inflação, evolução da população (em número de habitantes), evolução da migração líquida, evolução do Índice de Desenvolvimento Humano, evolução do Índice de Gini, evolução do número de pessoas com acesso a saneamento adequado em percentagem da população total, evolução dos indivíduos que utilizam a Internet em percentagem da população total. Espera-se que esta pesquisa contribua para a compreensão do crescimento económico da Guiné-Bissau, facilitando uma visão integrada de indicadores económicos e sociais do território. Da análise efetuada, foi possível identificar os desafios que a economia da Guiné-Bissau enfrenta, não apenas em termos económicos, mas também em termos políticos e sociais, decorrentes do facto de o país tem um sistema democrático relativamente jovem e que carece de estabilização. Importa ainda destacar o papel que o Estado deve desempenhar na formulação, desenho e implementação de políticas que poderão conduzir a economia do país a uma situação mais estável, possibilitando a estabilidade, por via de uma melhoria contínua e consolidada das diversas dimensões associadas à desigualdade, exclusão, educação, participação cívica e infraestruturas, entre outras.

  • From likes to comments: tracking interaction trends on social networks to promote cultural events
    Publication . Ferreira, Jessica; Scalabrini, Elaine C.B.; Lopes, Isabel Maria; Pereira, João Paulo; Cardim, Sofia
    Tourism drives the economy through job creation and infrastructure development, while the cultural component, such as gastronomy and historical heritage, enriches the visitor experience and reduces regional disparities. Municipalities use channels like Instagram to promote cultural events and strengthen local identity, reaching a diverse audience and encouraging community and visitor engagement. This study explores interaction trends in event posts on Bragança, Portuguese City Municipality’s Instagram from 2020 to 2023. The aim is to analyse the evolution of metrics such as likes, comments and views over the last four years. Using a quantitative approach, data was collected from Instagram posts using the APIFY platform, followed by an analysis using Python for statistical evaluation to identify correlations and patterns. The main results reveal significant variations in user engagement with different types of events and changes in follower behaviour over time. These findings offer valuable information for social media management and municipal event planning, emphasising the importance of adaptive strategies on digital platforms.

  • From reviews to emotions: analysing Bragança’s tourism attractions on TripAdvisor
    Publication . Scalabrini, E.C.B.; Ferreira, Jessica; Fernandes, Paula Odete; Moraes, Thiago
    Over the past decade, sentiment analysis has emerged as a pivotal tool in tourism-related texts, driven by the sheer volume of tourist attractions and the wealth of online information. Tourists increasingly turn to travel websites to access specific information that often eludes standard evaluations of tourist attractions. Forums particularly illuminate specific information needs and their ties to potential destinations. Among these platforms, TripAdvisor has become a favoured choice for posting reviews, ratings, and facilitating online bookings. In this context, this study aims to analyse and assess sentiment in reviews sourced from the online platform TripAdvisor, focusing on tourist attractions in the northern Portuguese destination of Bragança. The research spotlights the disparity between qualitative and quantitative rankings. The study also underscores the importance of data pre-processing, including removing irrelevant information and stop words. Pre-processing was crucial in refining sentiment prediction accuracy, highlighting the differentiated roles of these words in context and meaning. Despite utilising advanced techniques such as tokenisation, TF-IDF weighting, logistic regression, and n-grams, the study‘s models encountered challenges in achieving high accuracy in sentiment prediction. Even the incorporation of bigrams did not yield substantial performance improvements, with the models frequently inclined to overestimate negative and positive sentiments.

  • Historical and cultural perspectives on obesity and body image in Portugal
    Publication . Meireles, Manuela; Ferro-Lebres, Vera; Almeida-de-Souza, Juliana; Podestá, Olívia Galvão de; Machado, Ana; Ferreira, Jessica; Pereira, Fernando A.
    Portuguese adolescents and young people are subject to normative discontentment related to body image perception. This perception is subjective and influenced by several factors including mass media communication or social media messages. To aggravate this situation, we live in a pro-obesogenic era. Advertising for unhealthy food facilitates excess body weight which in turn contributes to body dissatisfaction and to the manifestation of eating disorders. We analyzed the covers of printed magazines from the last 13 months to understand how body image is portrayed in actuality. Of the total magazines, 29% have messages related to beauty culture. Some of them were related to weight or body shape such as “body in shape” (“Corpo em forma”), and “prepare the body for summer” (“prepare o corpo para o verão”). Only 15 (9.4%) of those magazines are assisting the slenderness culture: “Easter without gaining weight” (“Páscoa sem engordar”), “After holidays lose weight” (“depois das férias perder peso”), “do not come back with more weight from holidays” (“não volte com mais peso das férias”), “loose weight for once” (“emagreça de vez”), and “loose x kg in y weeks (“emagreça x kg em y semanas”). From the total of magazines, 8.5% (14 magazines) were identified as having body shaming, inducing that a change was necessary to have a desirable body. Despite these results, excess body weight is still a target of social stigma and bullying at scholarly levels. However, movements of body positivity and TV shows increasing awareness of how stigma affects people suffering from obesity and eating disorders are becoming more common opening space for improvements in the next years, that will undoubtedly need a multidisciplinary integrated approach to succeed.
