- Customer experience and customer satisfaction : assessing links and themes in the hotel industryPublication . Sampaio, Carlos; Régio, MónicaHotel industry provides several services simultaneously to customers and plays a relevant role within the tourist sector and overall economic development. This study seeks to explore the interaction between customer experience and customer satisfaction in the hotel industry and to analyse factors affecting customer satisfaction and purchasing intentions. To conduct the analysis, a thematic and a co-citation analysis have been applied to scientific literature output. Results show that word-of-mouth has been mostly replaced by electronic word-of-mouth and online reviews gained relevance in influencing customer behaviour. Purchasing decisions, determinants of service quality, particularly those related with physical settings and environments, are critical to customer experience and customer satisfaction, and employees and job-satisfaction are among the most relevant themes within the research stream. This study also provides several relevant implications and guidance to academics and practitioners and some hints for further research.
- Prevalence and clinical features of adverse food reactions in portuguese adolescentsPublication . Lozoya-Ibáñez, Carlos; Nunes, Sara; Rodrigues, Alexandra; Fernandes, Patrícia; Lourenço, Olga; Fonseca, Ana; Barata, Luís TabordaBackground & aims: The objective of the present study was to determine, for the first time, the prevalence and clinical features of food allergy in Portuguese adolescents. Methods: Cross-sectional study performed in various secondary schools in central Portugal. Randomly selected adolescents replied to a validated food allergy questionnaire. Those who reported an adverse food reaction were seen at participating hospitals, where clinical history was taken, skin prick (SPT) and prick-prick skin (SPPT) tests were performed, and food allergen-specific IgE levels (sIgE) were determined. An open oral challenge was performed in selected cases. Cases of positive clinical history of immediate (up to 2 h after ingestion) reaction in association with positive food sIgE levels and/or SPT were classified as IgE-associated probable food allergy and as confirmed IgE-mediated food allergy if food challenges were positive. Cases of positive clinical history of delayed (more than 2 h after ingestion) and negative food sIgE levels independently of positive SPT or SPPT results, were classified as non-IgE associated probable food allergy. Results: The prevalence of probable food allergy in Portuguese adolescents was 1.41% (95% CI: 0.90–2.03%), with fresh fruits, shellfish, nuts, and peanut as the most frequently implicated foods. IgE-mediated probable food allergy occurred in 1.23% (95% CI: 0.67–1.72%) of cases, with fresh fruits, shellfish, and nuts mainly involved. Cutaneous symptoms were most frequently reported. Conclusions: The prevalence of probable food allergies in Portuguese adolescents is low, is mostly related to fresh fruits, shellfish, nuts, and peanut, and most frequently involves cutaneous symptoms.
- Steroid hormone levels in postmenopausal hysterectomised women with and without ovarian conservation: the continuous endocrine function of the ovariesPublication . Nunes, Elsa; Gallardo, Eugenia; Nunes, Sara; Moutinho, José FonsecaThis study aims to clarify the effect of postmenopausal bilateral oophorectomy on plasma steroid hormone levels. Women who were submitted in the postmenopausal period to hysterectomy for uterine benign conditions were divided into two groups: 18 women had isolated hysterectomy and 11 had hysterectomy with bilateral salpingo-oophorectomy. In both groups serum hormone levels were quantified by solid phase extraction and gas chromatography and tandem mass spectrometry. Differences in dehydroepiandrosterone (DHEA), testosterone, androstenedione and oestradiol were determined in both groups. The analysis revealed lower steroid levels in the bilateral salpingo-oophorectomy group when compared to the isolated hysterectomy group with statistically significant differences found for DHEA (5.8 ± 3.2 vs. 9.4 ± 4.4 ng/mL; p ¼ 0.019) and oestradiol (0.69 ± 0.4 vs. 1.48 ± 4.3 ng/mL; p ¼ 0.007). The results are consistent with a significant endocrine activity of the postmenopausal ovary. The clinical consequences of these findings need to be clarified and postmenopausal prophylactic bilateral salpingo-oophorectomy re-evaluated.
- Steroid hormone levels and bone mineral density in women over 65 years of agePublication . Nunes, Elsa; Gallardo, Eugenia; Nunes, Sara; Moutinho, José FonsecaPrevious studies using immunoassays for steroid measurements have focused on the association between steroid hormone levels and bone mineral density (BMD) in postmenopausal women, obtaining contradictory results. This study aimed to assess this association using a highly sensitive bioanalytical method. A total of 68 postmenopausal women, aged 65–89 years, were enrolled in a crosssectional study. Measurements of the BMD of the hip and lumbar spine were performed using dual energy Xray absorptiometry, and serum hormone levels were quantifed by gas chromatography and tandem mass spectrometry. Associations between estradiol (E2), testosterone, dehydroepiandrosterone (DHEA), androstenedione and T score levels of the hip and lumbar spine were evaluated, after adjustment for confounding variables. The analysis revealed a statistically signifcant association between testosterone and the T score of the hip (p= 0.035), but not that of the lumbar spine. No statistically signifcant associations were found between E2, DHEA, androstenedione and the T scores of the hip and the lumbar spine. Using a highly sensitive hormone assay method, our study identifed a signifcant association between testosterone and BMD of the hip in women over 65 years of age, suggesting that lower testosterone increases the risk of osteoporosis.
- The influence of students’ perceptions and motivation on accounting and taxation careersPublication . Sampaio, Carlos; Régio, Mónica; Sebastião, João RenatoCompanies depend on the trust and confidence of the general public to thrive. The integrity of financial reporting practices plays a pivotal role in establishing and sustaining stakeholders’ confidence. This trust serves as a foundational cornerstone in managerial decision-making processes and in facilitating the active participation of a diverse spectrum of stakeholders within organizational frameworks. Despite its reputation for ethical and transparent conduct, the field of accounting often grapples with a perception of mundanity, particularly among student populations. This study uses a structural equation modeling approach to assess the impact of students’ perceptions of the accounting profession on their motivation in academic coursework, using a sample of 92 undergraduate students of accounting and taxation subjects. Additionally, it seeks to investigate how this motivation directly influences their perceptions of future career and how it operates indirectly through their active engagement in accounting and taxation courses. The research findings indicate that students’ perceptions of the accounting profession have a direct and positive effect on the perceptions of future career of individuals enrolled in both accounting and taxation courses. This influence is further mediated by the levels of motivation and engagement observed in the academic domain. Moreover, the results highlight the direct and positive influence of students’ motivation and engagement in their coursework on their perceptions of future career.
- Social innovation and social entrepreneurship : uncovering themes, trends, and discoursePublication . Sampaio, Carlos; Sebastião, João RenatoThe world is marked by persistent and recurring socio-economic and environmental changes. The domains of social innovation and social entrepreneurship have gained prominence as catalysts for positive change and societal resilience. Despite the substantial body of literature assessing social innovation and social entrepreneurship, most studies address these topics through analyses of scientific production output or through systematic literature reviews. Conversely, the main objective of this paper is to conduct a thematic analysis of the existing scientific literature on social innovation and social entrepreneurship, published across various geographical contexts, to assess themes, trends, and discourse within these fields worldwide. Therefore, it synthesizes, analyzes, and evaluates the evolving landscape of social innovation and social entrepreneurship research over time, employing a sliding windows methodology. This approach divides the analyzed period into distinct times to meticulously track changes in themes and discourse over time. To accomplish this objective, this paper examines the evolving thematic dynamics of social innovation and social entrepreneurship within the scientific literature, serving as a driver and compelling researchers and practitioners to explore new dimensions in social innovation and social entrepreneurship. Evidence from the analysis is discussed, including the main theoretical and practical implications and proposals for future research. This paper emphasizes the importance of adaptive and resilient approaches within the domains of social innovation and social entrepreneurship and contributes to a deeper understanding of how social innovation and social entrepreneurship evolve and adapt over time, shedding light on the transformative potential of social innovation and social entrepreneurship.

Sampaio, Carlos; Farinha, Luís; Sebastião, João Renato; Fernandes, António MarquesAlthough entrepreneurship plays a critical role in fostering economic development, erasing inequality, and generating more balanced societies, a gap concerning the course, nature, and state-of-the-art of minority entrepreneurship scientific literature need to be fulfilled. A hybrid methodology, combining bibliometric methods and topic models (latent Drichlet allocation) is used to perform a thematic analysis of the minority entrepreneurship research stream. The analysis provides insight into the most relevant research themes as well as further research agenda.
- Tourism industry at times of crisis: a bibliometric approach and research agendaPublication . Sampaio, Carlos; Farinha, Luís; Sebastião, João Renato; Fernandes, António MarquesDesign/methodology/approach This study uses bibliometric methods and topic models, specifically latent Dirichlet allocation (LDA) methods to evaluate the nature and course of the tourism crises and disasters scientific literature. Data from 2810 documents were retrieved from the Web of Science database and were used to perform the analysis. Purpose The COVID-19 pandemic caused unprecedented global turmoil and a halt on international tourism. This study aims to evaluate the scientific literature about tourism crisis and disasters and depict how this research stream evolved in the face of economic, security, health, environmental, or trust crises, further providing insights about a research agenda on this stream. Findings Results show an increase of tourism crises and disasters scientific literature departing from 2010, and a surge in 2020 and 2021 due to the COVID-19 pandemic. Furthermore, themes such as tourism competitiveness, tourism demand, crisis management, perceived risk, natural disasters, and destination recovery are among the most relevant themes in the research line, showing that the effect of economic and financial crises on tourism industry, sustainable tourism, and tourism demand are set to be among the most relevant in the upcoming years. Implications This study fills a void in tourism literature by providing a roadmap to understand the past, present, and future of the tourism crises and disasters research line and the avenues for future research in this field, including methods, in the period post COVID-19. Originality/value Previous studies on tourism crises and disasters were focused on literature review and on the relationship between crises and disasters and the tourism industry. This study uses a set of methods unused before in the research stream, namely a combination of bibliometric methods and latent Dirichlet allocation (LDA) methods, to provide a road map for the present state-of-the-art of tourism crises and disasters research and promising future research lines.
