- Antibacterial, antioxidant, and antiproliferative activities of corymbia citriodora and the essential oils of eight eucalyptus speciesPublication . Miguel, Maria da Graça; Gago, Custódia; Estêvão, Maria Dulce da Mota Antunes de Oliveira ; Lagoas, Soraia; Faleiro, Maria Leonor; Megías, Cristina; Cortés-Giraldo, Isabel; Vioque, Javier; Figueiredo, Ana CristinaBackground: Essential oils (EOs) have shown antimicrobial, antioxidant, and antiproliferative activity, which may, alone or in combination with other substances, potentially be used for the development of new drugs. However, their chemical variability, depending on the species, varieties, or geographical origin (among other factors) determines different bioactivities that need to be evaluated. Methods: The antioxidant activity of Corymbia citriodora and eight Eucalyptus species EOs was determined using two different methods: the scavenging ability of 2,20 -azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS+• ) and peroxyl free radicals or oxygen radical absorbance capacity (ORAC). Antibacterial activity was evaluated using the microorganisms Streptococcus pneumoniae (strains D39 and TIGR4), and Haemophilus influenza (strain DSM 9999). The essential oils’ minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) was assessed using a microdilution method. The antiproliferative activity was determined using the THP-1 cell line (human acute monocytic leukaemia) with methylthiazolyldiphenyl-tetrazolium bromide assay (MTT). Results: Corymbia citriodora and Eucalyptus viminalis EOs showed the highest ABTS and peroxyl free radical scavenging capacity. Eucalyptus globulus EO showed a high potential to treat Streptococcus pneumoniae infections. Haemophilus influenzae was the respiratory pathogen that showed the highest resistance to all EOs, including tea tree EO. After 96 h of incubation, at 25 µg/mL, Eucalyptus radiata and Eucalyptus viminalis EOs showed highest cytotoxic activity against the THP-1 cell line. Conclusions: Despite their specific bioactivities, no single EO showed simultaneously good antioxidant, antimicrobial, and antiproliferative activity.
- A bibliometric analysis: wine tourism in the sectorPublication . Gómez-Carmona, Diego; Marín-Dueñas, Pedro Pablo; Correia, Marisol B.; Escobar, Marta Toribio; de Matos, Nelson Manuel da Silva; Cruces-Montes, Serafín JesúsThe term “wine tourism” was first used in 90’s from Australia. The definition of ecotourism has been studied by many academics throughout its history, reaching the conclusion that it is the activities carried out by people outside their usual environment in a given period of time related to the viticulture of the environment and wine. This study aims to enhance knowledge in the wine tourism field by employing bibliometric methods to quantitatively analyze its evolution over the past two decades. This analysis shows that from 2019 onwards, publications increased considerably, reaching a peak in 2020, mostly (linking with COVID-19 lockdown). In the areas of geography and economics, as research in the area of tourism is still very recent. The conceptual analysis shows the variety of terms used by researchers and how they have evolved over time, the most commonly used being "touristic" and "vineyard", with others appearing such as "meal" connected to "winery waste" or "tourism development", which are more akin to current management.
- Can sudden fluctuations in tourism demand influence the earnings management practices of the hotel industry? Evidence from PortugalPublication . Gonçalves, Beatriz; Serra Coelho, Luís Miguel; Pinto, PatríciaThis study examines how sudden shifts in tourism demand affect the Earnings Management (EM) strategies of hotel firms, using Portuguese companies as the study context. This paper uses accounting data from 490 non-listed Portuguese hotel firms collected from the ORBIS database over the 2016-2021 period. The presence of EM practices is investigated using the methodology developed by Burgstahler and Dichev (1997), while panel data regression is used to explore the impact of the COVID-19 pandemic on the sample firms' EM practices. Portuguese hotel firms use EM practices upward or downward depending on their starting position. In general, these firms tend to manipulate results in order to avoid reporting losses, a practice they intensify when faced with a sharp decline in demand. In particular, this paper finds that, during the recent pandemic period, such companies have aggressively used the discretionary component of accruals to disclose higher results. To the best of our knowledge, this is the first article exploring how a sudden decline in tourism demand affects the EM behaviour of firms operating in the hospitality sector. Our findings have important implications for such companies' stakeholders, especially investors and regulators.
- Certification, maintenance and decertification of standardised innovation management systems: Motivations, barriers and benefitsPublication . Mendes de Saboya , Liana; Candido, Carlos Joaquim Farias; Cesário, MarisaThe role of standardised innovation management systems (SIMS) in fostering organisational innovation has been largely overlooked in the literature. This study addresses this gap by investigating the certification, maintenance, and decertification of SIMS. Using a descriptive and inductive methodology, the research analyses primary data from 94 Portuguese organisations with certified SIMS. The findings reveal a strong prevalence of internal motivations for certification, low implementation obstacles, and significant benefits, suggesting that these firms have successfully internalised the SIMS standard into their innovation management processes. Maintenance motivations are also strong, particularly internal ones, which align well with the critical success factors for sustaining certification. The benefits of maintaining SIMS are substantial, particularly internal benefits, as initial external motivations for certification often evolve into internal maintenance motivations. Decertification motivations and propensity are weak among the sample firms. Expectations of negative performance impacts following potential decertification are also low, likely because these organisations have effectively internalised the SIMS standard. This study is the first to explore the maintenance and decertification of SIMS, providing evidence that SIMS can deliver substantial benefits, be efficiently maintained, and continuously enhance innovation and competitiveness. As a result, most organisations exhibit little interest in decertification. The findings offer significant contributions to research and provide actionable insights for practitioners, suggesting that innovation management systems can indeed be standardised with considerable benefits.
- Destinationscape: an integrated and holistic conceptualizationPublication . Bender, Ana Carolina; Agapito, Dora Lúcia Miguel; Martins Guerreiro, Maria ManuelaDestinations are growingly acknowledged as dynamic entities requiring strategic resource management to provide value for stakeholders. In this sense, to be recognized as desirable places to visit, to live or to invest in, with a harmonious integration among the stakeholders, it is imperative to frame destinations’ distinctiveness using the experience marketing perspective. Through a combination of an integrative literature review and an academic panel with diverse expertise, this conceptual research aims to conceptualize and depict the environmental features composing destinationscape as a construct, considering the dynamic interplay of multiple ‘scapes’. As a result, the proposed conceptual framework comprises five second-order and 17 first-order dimensions. This research is expected to contribute to the theory around destination experience and experiencescape by offering a comprehensive view, where destinationscape emerges from continuous interactions between the destination’s external environment and its stakeholders. Consequently, this research contributes to destination competitiveness and governance by conceptualizing and providing a framework around destinationscape.
- Factors influencing the choice of the Algarve region as a tourist destination: does season matter?Publication . Barreira, Ana Paula; Cesário, MarisaThe dissimilar ways in which tourists assess the attributes of a tourism destination in different seasons is an issue scarcely addressed in the literature. Here, we show that the characteristics of a tourism destination (the Algarve region, Portugal) are rated differently in peak (summer) and off‐peak (autumn/winter) seasons. Nationality is decisive in explaining the different assessments between seasons of the factors that group subsets of 17 attributes of the tourism destination. In general, the factors that are rated higher by domestic tourists during the summer are the same as those that are rated higher by foreign tourists in the autumn/winter.
- From destination attributes to tourist satisfaction: novelty-seeking as a bridge between liminality and place attachmentPublication . Lança, Milene; Nobre Pereira, Luis; Silva, joão; Andraz, Jorge; Cunha Sousa Nunes, Rui JoséThis study analyses how destination attributes influence tourist satisfaction via perceived quality, price, and safety, and how these relationships differ by novelty-seeking orientation. Framed at the intersection of liminality and place attachment, novelty-seeking is conceptualised as the behavioural mechanism linking extraordinary experiences to emotional bonds with place, offering the first empirical integration of these frameworks in tourism research. Using data from 1,488 tourists visiting the Algarve (Portugal) in 2022–2023 and Partial Least Squares Multigroup Analysis (PLS-MGA), the results show that for conservative tourists, destination attributes enhance perceived quality, lower perceived prices and safety concerns, and increase satisfaction. For adventurous tourists, satisfaction is driven mainly by perceived price and is negatively affected by in situ safety concerns, indicating that novelty-seekers do not uniformly discount risk. The findings highlight how novelty-seeking conditions cognitive pathways to satisfaction and inform market segmentation strategies aligned with distinct motivational orientations.
- Recovering a lost ISO 9001 certification: what is the economic impact?Publication . Candido, Carlos Joaquim Farias; Serra Coelho, Luís Miguel; Peixinho, RúbenThis study assesses the economic impact of ISO 9001 certification recovery following a medium-term period of withdrawal. Data from the Amadeus database is used to implement an event study that matches a sample of Portuguese companies that recover their ISO 9001 certification after operating a full year without such certification with a set of similar but, non-event, counterpart firms. Results show no statistically significant differences in the economic performance of the two groups of companies as measured by the return-on-assets, return-on-sales, and sales growth ratios. Contrary to the predictions of the current theory, this study suggests that certification recovery under ISO 9001 is neither beneficial nor detrimental to firm performance since such an event has no significant impact on the economic performance of the sample companies. This suggests that the decision to recover a lost certification is economically irrelevant for firms that experienced a one-year lag without being certified. This is one of the first studies to assess the impact of ISO 9001 certification recovery after a period of certification withdrawal, and the first to do so exclusively from a financial perspective. The study contributes to understand why only a small proportion of decertified companies (17%) subsequently recover their certification.
- Show me the money: A systematic literature review on financial transparency and USALI’s global adoption challengesPublication . Elston, Jennifer Nicole; Coelho, Luis; Peixinho, RúbenThis systematic literature review explores the adoption and implementation of the Uniform System of Accounts for the Lodging Industry (USALI) across 25 studies, including academic articles and grey literature. This review aims to shed light on the diverse experiences of hotels adopting USALI by examining its impact on financial transparency, cost allocation practices, benchmarking capabilities, and sustainability reporting within the global hospitality sector. While larger, chain-affiliated hotels tend to benefit from full compliance, smaller independent hotels often struggle due to limited resources and the system’s complexity. The introduction of the 12th edition of USALI in 2024, which includes new Energy, Water, and Waste (EWW) metrics to promote sustainability, presents additional challenges for smaller hotels. Findings underscore the importance of USALI for benchmarking and management within hospitality units and highlight the need for future research into simplified, scalable USALI solutions. Such developments would make this management accounting system more accessible to smaller hotels and emerging markets, allowing them to realize its long-term financial benefits.
- Smart innovation strategy and innovation performance: an empirical application on the Portuguese small and medium‐sized firmsPublication . Cesário, Marisa; Fernandes, Silvia C. Pinto de BritoSmart Innovation is often considered as the capability of firms to create new opportunities through a dynamic relationship with the main actors in their setting, fostering higher innovation performances and sustainable competitive advantage. However, innovation indicators of Portugal in Europe show that Portuguese firms miss an open innovation strategy to cope quick and easily with complex new challenges. Relying on the results from the Community Innovation Survey (CIS 2014) this paper focuses on the analysis of the relationship between a smart‐open innovation approach and firms’ innovation performance in the sample. Furthermore, and using the LINEAR (automatic linear modelling) procedure in SPSS 24.0, statistically significant relationships are established between proxies for smart‐open innovation and a score for innovation performance. The findings provide relevant conclusions about how Portuguese firms should explore their networking strategies, both in terms of scale (or smart ‐ local/geographically) and scope (or open ‐ a variety of agents) in order to match their innovation to market, toward a continuous business value.
