- From host's descriptions to guests' reviews: semantic similaritiesPublication . Cavique, Mariana; Ribeiro, Ricardo; Batista, Fernando; Correia, AntóniaThis study investigates the semantic alignment between Airbnb property descriptions and guest reviews. Word2Vec embeddings and affinity propagation clustering are used to identify granular semantic concepts, enabling a detailed comparison of the two text types. A new metric, concept coverage ratio, is introduced to measure the extent to which the guest review content is reflected in property descriptions. Results show that a higher concept coverage ratio is generally associated with more positive sentiment in reviews, suggesting that better alignment between host and guest perspectives contributes to guest satisfaction. However, longer and detailed descriptions may limit the potential for pleasantly surprising guests, as it reduces the chance for positive disconfirmation. These findings offer practical insights for improving communication in peer-to-peer accommodation.
- Factors influencing access to finance among jordanian SMEs: examining the role of P2P lending fintech, information asymmetry, transaction cost, and financial literacyPublication . Doumi, Ammar Fakhri; Begum, Halima; Doumi, Fakhri Bani; Alam, A. S. A. FerdousThe aim of this research is to examine the correlation between Peer-to-Peer (P2P) lending financial technology (Fintech), information asymmetry, transaction cost, financial literacy, and access to finance among Small and Medium Enterprises (SMEs) in Jordan. The study used Partial Least Squares-Structural Equation Modelling (PLS-SEM) to analyze data collected from a sample of 335 SMEs in Jordan. The study’s findings indicate that information asymmetry and transaction cost have a notable and adverse impact on access to finance. On the other hand, P2P lending Fintech has no direct effect on access to finance. Additionally, financial literacy significantly moderates the relationship between P2P lending and access to finance among SMEs. In conclusion, P2P lending Fintech has been proven to help Jordanian SMEs’ access financing when financial literacy interacts as a moderator. This study contributes to the extant literature on how financial literacy moderates the relationship between P2P lending and SMEs’ access to finance. Finally, the results of this research benefit SMEs’ owners/managers by providing them with empirically validated insights into the factors that affect their ability to access financing. Additional research should investigate many categories of Fintech tools, such as crowdfunding, blockchain, and other related technologies. Furthermore, it is necessary to examine additional factors that impact the ability to get financial resources, such as collateral and management risk, and it is important to assess the influence of financial management regulations on these factors.

- Institutional ownership, free float, and systematic riskPublication . Francisco, Paulo MoraisThis study investigates how institutional ownership (IO) and free float (FF) jointly affect firms’systematic risks. It contends that larger institutional stakes increase the dollar imbalance subject tocommon flows, whereas a greater tradable float broadens the set of funds that can tradesynchronously. Both channels should increase the stock market beta. Using a cross-section of12,655 non-financial firms from 93 countries, unconditional, downside (β−), and upside (β+) capitalasset pricing model betas over two-, three-, and five-year windows are analysed. The resultsconfirm that IO and FF are positively and significantly associated with unconditional and downsidebetas. These relationships remain robust after controlling for firm size, valuation, profitability,leverage, liquidity, and industry fixed effects, indicating that the ownership and tradability chan-nels explain systematic risk beyond standard fundamentals. The impact of IO is pronounced forupside beta. Two-stage least squares regressions corroborate the baseline results while addressingendogeneity concerns. Additional tests show that the IO effect is concentrated in advancedeconomies, while the FF effect remains robust across geography, development status, and firmsize. This study evinces the trading flow hypothesis that ownership concentration and tradabilityare the additive drivers of systematic risk.
- 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.
- Impression management, government agencies' regulation and analyst forecasts: empirical evidence from an emerging marketPublication . Castro, Lívia Arruda; Ponte, Vera; Viana Junior, Dante Baiardo C.Purpose- This study aims to investigate the relationship between government agencies' regulation and analyst forecasts in an emerging market and whether this relationship is mediated by impression management in earnings press releases.Design/methodology/approachThe sample consists of 1,816 quarterly observations of Brazilian listed firms from 2003 to 2021, based on data from Thomson Reuters (R). The impression management of the sample firms is obtained by analyzing their earnings releases using the Watson Natural Language Understanding (NLU) platform developed by IBM (R). We employ a manual firm-level classification procedure to detect regulated and non-regulated firms by government agencies.FindingsBased on structural equation modeling, the findings suggest that firms regulated by government agencies present, on average, lower levels of impression management in earnings press releases. Additionally, we find that the level of firms' impression management, in turn, is negatively related to analyst forecast errors. These empirical results indicate that impression management in earnings press releases is a crucial mediating channel between government agencies' regulation and analyst forecast errors. Moreover, we find that government agencies' regulation has a positive and direct effect on analyst forecast errors, possibly due to its impact on other firm-level incentives and market dynamics, which may be positively or negatively associated with analyst forecasts.Originality/valueThis study contributes to the previous literature on the relationship between government agencies' regulation and analyst forecasts by theoretically discussing and empirically analyzing the mediating role of impression management as an important factor in this relationship, exploring the various facets through which state regulation ends up changing the structure of the informational environment in which companies are located. An important debate for the emerging markets literature is also provided, and policy discussions are featured.
- 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.
- Stakeholders’ engagement on nature-based solutions: a systematic literature reviewPublication . Ferreira, Vera; Barreira, Ana Paula; Loures, Luís; Estêvão, Maria Dulce da Mota Antunes de Oliveira ; Panagopoulos, ThomasCities are facing a broad range of social and environmental challenges due to the current pressure of global urbanization. Nature-based solutions aim to utilize green infrastructure to improve people’s health and wellbeing. The design of urban environments must embrace the individual ideals of citizens and stakeholders which can only be achieved if effective methods of communication, involvement, and feedback are ensured. Such a procedure creates trust during its implementation, helping to take ownership and stewardship of processes and sites. This systematic literature review explores the current state of the art regarding citizen and stakeholder participation in nature-based solutions (NBS). The search on the SCOPUS database identified 142 papers in total that met the inclusion criteria. The participation analysis was separated in two areas: (a) analysis of perceptions, preferences, and perspectives of citizens and stakeholders, and (b) analysis of the participation process, including challenges and opportunities, motivations, methods and frameworks, and collaborative governance. The results revealed that stakeholder and citizen participation or collaboration in nature-based solutions is increasingly recognized as promising; however, research in several related domains is still lacking.
- 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.
- 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.
