- Resident empowerment in all-inclusive context: cost–benefit perception and support for sustainable tourism development in a small island destinationPublication . Santos, Edson Redy Moreira dos; Nobre Pereira, Luis; Pinto, Patrícia; Ribeiro, Manuel AlectorThis study examines the relationships among resident empowerment, perceptions of tourism costs and benefits, and support for sustainable tourism development (SSTD) in a small island destination dominated by all-inclusive resorts. Using survey data from 341 residents in Cape Verde and employing PLS-SEM analysis, results reveal significant relationships between empowerment, benefits, and SSTD. The perception of all-inclusive resorts' positive impacts moderates the relationship between empowerment and SSTD, while the perception of all-inclusive resorts' costs does not moderate any relationships. The study contributes to understanding how all-inclusive tourism development influences resident attitudes and support for sustainability in small island contexts. The findings underscore the importance of empowering residents and managing perceptions of tourism impacts to foster SSTD. Practical implications include the need for policies that promote local empowerment, equitable benefit distribution, and mitigation of negative impacts to ensure long-term sustainability of small island destinations and beyond.
- Green HRM’s effect on employees’ eco-friendly behavior and green performance: a study in the portuguese tourism sectorPublication . Gomes, Daniel R.; Ribeiro, Neuza; Gomes, Gabriela; Ortega, Eduardo; Dias Semedo, Ana SuzeteAbstract: This study examines how Green Human Resource Management practices improve employees’ eco-friendly behavior and green performance, and the mediator effect of affective commitment in these relationships. Our sample included 449 employees, from different Portuguese tourism organizations. The results demonstrate that the implementation of Green Human Resource Management practices produces a positive effect on eco-friendly behavior, green performance, and affective commitment, with commitment mediating the mentioned relationship. Therefore, when organizations apply greener Human Resources Management, they might influence positively the attitudes and behaviors of their employees, improving their affective commitment and, consequently, their ecofriendly behaviors and green performance. This research is innovative as it integrates Green Human Resource Management, eco-friendly behavior, green performance, and affective commitment in a single research model, expanding the knowledge over these topics, and suggesting that organizations should establish Green Human Resource Management policies, especially those that strengthen employees’ affective attachment and improve their eco-friendly behavior as well as the organization’s green performance.
- Navigating uncertainty: enhancing hotel cancellation predictions with adaptive machine learningPublication . Silvestre, Pedro; Antonio, Nuno; Carrasco, PauloAccurately predicting hotel booking cancellations is critical for hotel management, especially during volatile periods such as the COVID-19 pandemic. Prior work demonstrated that machine-learning (ML) models perform well on historical data, yet few studies test robustness under severe disruption. We evaluate ML classifiers trained on pre-pandemic data from four hotels and assess their adaptability to pandemic conditions (Study One). We then examine whether adding pandemic observations via a dynamic sliding-window approach improves accuracy (Study Two). Pre-pandemic models exhibit reasonable discrimination, but including pandemic-period data can raise the Area Under the Curve (AUC) by up to 5% points. A nine-month training window balances stability and responsiveness, capturing rapid shifts in booking patterns and customer behavior. Feature importance also changes: Lead time and other drivers show altered effects during the pandemic, underscoring the need for continuously updated models. Anchored in concept-drift theory, we interpret the pandemic as an abrupt shift in the cancellation decision boundary and show that sliding-window retraining together with interpretable diagnostics (e.g., the Lead time crossover threshold) provides a theoretically grounded blueprint for prediction under distributional change. Our results advocate scheduled retraining and lightweight drift diagnostics to sustain forecast accuracy and managerial actionability. For hotel managers and technology providers, the proposed approach supports proactive cancellation management, more reliable forecasting, and resilient operations in volatile markets, demonstrating the robustness of adaptive ML under conditions of extreme market volatility. The study advances theoretical understanding and practical applications by operationalizing concept-drift management in revenue-critical settings.
- Sex differences in health-related quality of life among individuals at high risk of dementiaPublication . Oliveira, Ana Sofia; Lopes, Sílvia; Ferreira, Lara; Cruz, Vítor Tedim; Costa, Ana RutePurpose Dementia represents an increasing challenge to health systems globally, with a notable impact on health-related quality of life (HRQoL). Nevertheless, the potential effect of sex on the relation between individuals’ characteristics and HRQoL, particularly in the early stages of this disease, remains unclear. Therefore, the present study aims to evaluate the association between sociodemographic, lifestyle and health-related factors with HRQoL among individuals at high risk of dementia, according to sex.Methods This cross-sectional study was based on baseline data from the MIND-Matosinhos randomized controlled trial, targeting Portuguese adults at high risk of dementia [n=207; 59.9% female; median age=70.0 (interquartile range: 11)]. HRQoL was measured using the EQ-5D-5L. The associations between explanatory variables and HRQoL scores (dichotomized by the median) were quantified through odds ratios (OR) and 95% confidence intervals (CI), stratified by sex. Results Overall, females reported lower HRQoL when compared with males [median (interquartile range): 0.875 (0.190) vs. 0.923 (0.129); p=0.004]. Problems in mobility (43.6% vs. 27.7%; p=0.021), pain/discomfort (71.8% vs. 44.6%; p for interaction=0.020). Conclusion Health status is associated with HRQoL, distinctively amongst males and females. These findings emphasize the need for sex-specific public health strategies to improve HRQoL in a vulnerable population of individuals at high risk of dementia.
- 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.

- 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.
