- Building resilience in tourism firms: evidence from COVID-19Publication . Jesus, Carina; Serra Coelho, Luís Miguel; Ramos, CeliaMultiple factors determine tourism companies' capacity to resist and overcome disruptive events, such as pandemics or wars. This paper investigates this issue using a sensitivity index and finds that reductions in human capital, bigger size, and higher past profitability diminish resilience, while higher leverage and capital intensity strengthen it. Our findings further suggest that these effects differ across countries and underscore the negative consequences of Eurozone membership. This paper broadens our understanding of how companies can improve their resilience, providing valuable insights for future preparedness strategies for tourism firms and policymakers.
- Global spillovers between sustainable and traditional ETFS: crisis dynamics and policy implicationsPublication . Gabriel, Vítor Manuel de Sousa; Lozano, María Belén; Matias, Fernanda; Neves, Maria Elisabete; Rebelo, SandraThis paper examines the interconnections between segments of exchange-traded funds (ETFs), bridging the traditional financial perspective with the sustainability-driven approach based on the Sustainable Development Goals (SDGs) outlined in Agenda 2030. The analysis is endogenous, focusing on the shocks that emerge within the system composed of these segments. Utilizing daily data from six sustainable segments, each corresponding to different SDGs, alongside one traditional segment, spanning a sample period of approximately 14 years, the study reveals notable spillover effects. Specifically, the periods associated with the pandemic and the war in Ukraine were marked by a significant surge in information transmission across the segments. Furthermore, the findings indicate that sustainable segments exhibit a strong interdependence with their traditional counterparts, a dynamic that facilitates contagion risk and limits the effectiveness of portfolio diversification strategies.
- Recuperación de la historia olvidada y protección del patrimoninio: la huella de la esclavitud en el algarvePublication . López Romeo, María Ángeles; Ribeiro de Almeida, Claudia; Rodrigues Gonçalves, AlexandraEl Algarve es una de las regiones más turísticas de Europa, según el Observatório para o Turismo Sustentavel (INSTO) recibió más de cinco millones de visitantes en el último año". Además de un turismo estacional, con variaciones en el flujo de visitantes según la temporada de invierno o verano, nuestros municipios cuentan con una población procedente de distintos países de Europa que habitan de forma permanente o temporal haciendo de nuestra región un lugar multicultural y cosmopolita. La diversidad de culturas enriquece las sociedades modernas, pero el turismo también tiene algunos efectos negativos en relación con la cultura, a los cuales concedemos menor importancia tendiendo a priorizar los beneficios económicos y efectos sociales positivos, como la creación de empleo y riqueza que este genera. Entre los impactos negativos del turismo se encuentra la pérdida de identidad cultural, que se manifiesta en distintas facetas como son: la desaparición paulatina del comercio local tradicional artesanal y la aparición de comercios de producción estandarizada para consumo de turistas; la pérdida de la gastronomía local y la aparición de empresas multinacionales de comida rápida; la desaparición de tradiciones y costumbres relacionadas o no con la religión o con la forma de convivencia y participación de la ciudadanía en la vida social de los municipios, consecuencia inevitable de la temporalidad en el espacio habitado, que desvincula al ciudadano con su entorno social. La identidad cultural se refiere a las características más relevantes y autóctonas de una región, un pueblo о una comunidad. Aquello que hace de un territorio un lugar único con personalidad, y todo esto gracias al patrimonio inherente a dicho territorio, un patrimonio tangible, como monumentos obras de arte, parajes naturales, etc., y otro intangible, como la lengua, las costumbres, el folclore, etc. Es fundamental que una comunidad sea a capaz de reconocer todo lo que les identifica, valorarlo y conservarlo (Cepeda, 2018). Se debe potenciar el patrimonio cultural como factor de identidad de los pueblos frente a los procesos de globalización que padece el planeta, y fomentar la creación de productos de turismo cultural basados en el ocio activo y el patrimonio para hacer frente a la necesaria reconversión del sector turístico. La Carta Europea de Turismo Cultural (2022) advierte, que algunos aspectos de la evolución del turismo han dado lugar a usos fundamentalmente insostenibles de los recursos planetarios, incluyendo en ellos al patrimonio cultural y natural.
- Da página à tela e da tela à rota: “O Quatrilho” como impulsionador do roteiro agroturismo na cidade de Gramado, RS, BrasilPublication . Diaz, Ronaldo; Ferreira, Luciane Tedeschini; Baleiro, RitaO turismo literário e cinematográfico tem recebido atenção junto a gestores, influenciando educação, cultura e economia. Este estudo foca no roteiro literário-cinematográfico “O Quatrilho”, em Gramado, RS, Brasil, que combina turismo cultural e obras literárias/fílmicas. Iniciamos com uma análise teórica da relação entre literatura, cinema e turismo, seguindo com a análise da obra “O Quatrilho” e sua adaptação cinematográfica, destacando os elementos do roteiro. Utilizando perspectivas bakhtinianas (Bakhtin, 1997) e análise de conteúdo (Bardin, 2011), investigamos os comentários de visitantes no TripAdvisor. Os resultados mostram que o roteiro proporciona experiências autênticas e imersivas, mesmo para aqueles não familiarizados com as obras, sendo que os turistas destacam, nesse tour a hospitalidade, cultura local e simplicidade.
- Dynamics of hotel bookings: identifying key drivers of hotel conversion ratePublication . Luchi, Piero; Heo, Cindy Yoonjoung; Nobre Pereira, Luis; Viverit, Luciano; Contessi, DanieleAll hotels receive numerous booking requests every day, either directly or through online travel agencies, but only a small percentage of these requests are converted into reservations. Low conversion rates generate an additional layer of uncertainty into the hotel demand function and pose a challenge for revenue maximization. Consequently, optimizing the conversion rate is a top priority for all hotel managers. Despite its importance, the factors influencing the conversion rate are not yet well understood. This longitudinal study aimed to identify the factors that explain seasonal variations in the conversion rate, providing insights to optimize it. By segmenting stay dates using machine learning algorithms and employing a logistic regression model to predict the probability of conversion per segment, this innovative research proposes a framework for conversion rate optimization. The research note contributes a new data mining methodology that can be implemented in machine learning algorithms to enhance conversion rates
- Evaluating the impact of instagram engagement metrics on corporate revenue growth: introducing the loyalty ratePublication . Sanches, Eva; Ramos, CeliaThis research explores the impact of social media metrics on revenue growth, specifically focusing on Instagram, a leading platform for businesses to engage consumers and promote offerings. It examines key metrics such as reach, impressions, interaction rate, and virality rate, which gauge user engagement with brand content. A novel metric, the loyalty rate, is introduced, combining interaction and virality rates to measure follower loyalty-those who not only engage but also share content, enhancing organic reach. The methodology involved comprehensive statistical analyses, including descriptive statistics, Pearson's correlations, and regression models, to investigate the relationship between social media metrics and monthly turnover. The findings reveal a moderate positive correlation between the loyalty rate and turnover, although the statistical significance was insufficient to establish a direct relationship. In contrast, metrics like follower count exhibited a stronger influence on financial performance, indicating that follower growth may be more critical for revenue generation. This study concludes that while engagement and loyalty matter, their effect on turnover is part of a broader digital strategy encompassing various factors beyond direct interactions. Practical recommendations are made for enhancing the loyalty rate and expanding research to include other platforms, like Facebook and LinkedIn, for a more comprehensive understanding of social media's impact on financial outcomes.
- Building company resilience: Determinants in the tourism industryPublication . Jesus, Carina; Serra Coelho, Luís Miguel; Ramos, CeliaWhat characteristics enable a company in the tourism industry to withstand and recover from disruptive events such as a global pandemic or a war? How can these firms enhance their resilience? This paper presents a systematic literature review of peer-reviewed publications on company resilience within the tourism industry to address these critical questions. Despite the current significance of these topics, existing research is fragmented and unconsolidated. Our findings reveal a range of perspectives and factors that influence company resilience, with clear evidence that human capital plays a pivotal role in the tourism industry’s ability to remain resilient. We also identify theoretical and practical implications, along with directions for future research.
- User-generated content and its impact on purchase intent for tourism products: a comparative analysis of millennials and centennials on tiktokPublication . Ramos, Eva Correia; Ramos, CeliaIn an increasingly technological society, online social networks are essential to support consumer purchasing decisions, primarily through User Generated Content (UGC). In this research, we look at the influence of UGC on purchase intent applied to the tourism product on the TikTok social network. In this sense, a survey was applied to TikTok users aged between 18 and 42 to compare their behaviour with that of the two generations: Millennials and Centennials. The results indicate a relationship of influence between credibility and the usefulness of information and between usefulness and social influence on the intention to buy tourism products and services. In addition, a comparison was made between the results of the sample of individuals belonging to the Millennial Generation and the sample of individuals belonging to the Centennial Generation, with the main discrepancy in the results being the relationship between the need for information and the usefulness of information. These insights pave the way for further research aimed at establishing more robust conclusions in this area.

- Large language models powered aspect-based sentiment analysis for enhanced customer insightsPublication . Água, Mariana; António, Nuno; Carrasco, Paulo; RASSAL, CARIMOIn the age of social networks, user-generated content has become vital for organizations in tourism and hospitality. Traditional sentiment analysis methods often struggle to process large volumes of data and capture implicit sentiments. This study examines the potential of Aspect-Based Sentiment Analysis (ABSA) using Large Language Models (LLMs) to enhance sentiment analysis. By employing GPT-4o via ChatGPT, we benchmark three approaches: a fuzzy logic-based method, manual human analysis, and a new ChatGPT-based analysis. We analyze a dataset of 500 all-inclusive hotel reviews, comparing these methods to assess ChatGPT's effectiveness in identifying nuanced language and handling subjectivity. The findings reveal a high similarity between ChatGPT and human analysis, showcasing ChatGPT's ability to interpret complex sentiments and automate sentiment classification tasks. This study highlights the potential of LLMs in transforming customer feedback analysis, providing deeper insights, and improving responsiveness in the hospitality industry. These results contribute to academia by presenting a framework for using LLMs in ABSA and guiding future applications and development.
