- Bank Credit and Trade Credit: The Case of Portuguese SMEs from 2010 to 2019Publication . Pinto, Pedro; Henriques, Carla; Cardoso, Carolina Esteves Oliveira da Silva; Neves, Maria Elisabete DuarteSmall companies face significant difficulties in accessing finance, and the use of bank credit and trade credit are the primary sources of financing, specifically in small countries, with little market liquidity, and focused on the banking system, as is the case of Portugal. The main objective of this article is to identify significant drivers of bank and trade credit, as well as investigate the complementary or substitutive relationship between them, considering that both constitute an essential source of financing for small and medium-sized enterprises (SMEs). The sample comprises 5860 companies, and the analysis was performed using panel data methodology (2010–2019). The results suggest that, during the period in which the financial crisis was most felt in the country (2010–2013), companies intensified their demand for trade credit, and in the following years for bank credit. Our evidence does support the substitution hypothesis between trade and bank credit.
- Motivation-Based Segmentation of Visitors to a UNESCO Global GeoparkPublication . Amaro, Suzanne; Balula Chaves, Naír; Henriques, Carla; Barroco, CristinaGiven the sustained growth that Geotourism has experienced worldwide, it is crucial to gain a better understanding of geotourists. Therefore, this study aims to examine visitors’ motivations for visiting geoparks, segment them accordingly, and characterize each segment. An online questionnaire was developed to collect information from visitors of the Arouca Geopark—UNESCO Global Geopark and was completed by 607 who had visited this park at least once. Respondents were asked about their motivations for visiting the park using 18 items that were combined into fve dimensions through exploratory factor analysis. These dimensions (Escape, Relaxation and Enjoyment, Novelty Seeking and Nature, Knowledge, Socialization, and Sports and Adrenaline) were the basis for a cluster analysis that revealed four segments of visitors: the Want it All Geotourists (representing 27% of the sample), that have the highest levels for all motivations; the True Geotourists (19.9%) which highest levels of motivations were on the three motivations that typically defne a geotourist: nature/adventure, knowledge seeking, and socialization; the Sensation Seekers (34.4%) whose strongest motivations were sports/adrenaline and escape from routine; the Accidental Geotourists (18.6%) who scored lowest for all motivations and are motivated essentially by the escape from routine and by nature/adventure. These segments were then further profled based on other variables such as age, gender, satisfaction, and quality of experience. The segmentation and description of each segment found in this study provide a better understanding of the typology of visitors to geoparks, which is crucial for better management of such places.
- Quality-of-Life Perception among Young Residents and Visitors: The Impact of COVID-19Publication . Seabra, Claudia; Almeida, Sofia; Reis, ManuelThis research intends to measure the quality of life (QoL) perception, from the perspective of residents and tourists towards Coimbra, a city with an important World Heritage Site, as classified by UNESCO. In these times, preserving tangible and intangible heritage is so important for future memories. Identifying the QoL perceptions through the eyes of residents and tourists allows the improvement of the community well-being of the destination for both stakeholders. Starting from this assumption, this study aims to: (i) measure the tourists’ and residents’ perceptions on quality of life (QoL); (ii) analyze the impact of the COVID-19 pandemic on QoL perceptions, both from the tourists’ and residents’ perspective. To achieve these objectives, a questionnaire was disseminated to residents and tourists in two different phases, before and during the COVID-19 pandemic. Results show that in general, residents and tourists exhibited, in both periods, medium and high perceptions of QoL, with an exception made for the Urban Issues domain that decreased even more during the pandemic. Furthermore, the results show, for residents and tourists, that the perception of Urban Issues, Way of Life, Community Pride and Awareness, Economic Strength, and Recreation Amenities impact significantly and positively their Community Well-Being perception. New paths for academics and for practitioners are presented at the end, as well as limitations and evidence for future research.
- Definition of Low Disease Activity State based on the SLE-DAS: Derivation and validation in a multicentre real-life cohortPublication . Assunção, Helena; Jesus, Diogo; Larosa, Maddalena; Henriques, Carla; Matos, Ana; Le Guern, Véronique; Rubiño, Francisco; Silva, José A P da; Rua-Figueroa, Iñigo; Costedoat-Chalumeau, Nathalie; Doria, Andrea; Inês, Luís SObjectives To derive and validate a definition of low disease activity (LDA) for SLE based on the SLE Disease Activity Score (SLE-DAS), in a real-life multicentre cohort of SLE patients. Methods Derivation was conducted using data from a monocentric cohort of SLE (Portugal), and validation was performed in a multicentre cohort (Italy, France and Spain). The Lupus Low Disease Activity State (LLDAS) was used as comparator. We applied receiver operating characteristics curve analysis against the LLDAS to determine the cut-off of SLE-DAS for LDA using bootstrap methodology. In a second step, we tested a definition of SLE-DAS LDA that included: (i) the statistically derived SLE-DAS upper threshold for LDA and (ii) prednisone dose ≤7.5 mg/day. In the multicentre validation cohort, we assessed the classification performance of this SLE-DAS LDA definition. Results We included 774 patients, 300 in the derivation and 474 in the validation cohort. In the derivation cohort, the optimal cut-off to identify patients in LLDAS was SLE-DAS ≤2.48, presenting an area under the curve of 0.965 (95% CI 0.935, 0.994). When applied to the multicentre validation cohort, the SLE-DAS LDA definition showed a sensitivity of 97.1% and a specificity of 97.7% for LLDAS and an almost perfect agreement (Cohen’s Kappa = 0.933; P < 0.001). McNemar’s test found no significant differences between the two definitions (P = 0.092). Conclusion The SLE-DAS LDA is a validated, accurate and easy-to-use definition for classifying SLE patients in LDA state.
- Tratamento pré-hospitalar da dor traumática aguda: um estudo observacionalPublication . Mota, Mauro; Santos, Margarida Reis; Santos, Eduardo; Henriques, Carla; Matos, Cristina Bico Rodrigues de; Cunha, MadalenaObjective: To describe and analyze the effectiveness of nurses’ interventions in pain reduction among patients with traumatic injury. Methods: Prospective cohort study conducted in the Immediate Life Support Ambulances in Portugal from March 1, 2019 to April 30, 2020. We have collected data on the kind of interventions implemented and the time elapsed during rescue procedures. To investigate the course of acute trauma pain, a 11-point Numeric Rating Scale was used. Changes in the level of pain registered throughout the three assessment moments were studied using linear mixed-effects models with random intercepts to account for the repeated measurements conducted on the same patient. These changes were assessed before and after the administration of the pain relief interventions. Results: 596 patients were included in this study. Most of them were male (65.9%) and had a mean age of 53.05±19.72 years. There was a reduction in the average pain intensity of 2.44 points (p
- Modelling the phenological development of cv. Touriga Nacional and Encruzado in the Dão Wine Region, PortugalPublication . Rodrigues, Pedro; Pedroso, Vanda; Henriques, Carla; Matos, Ana; Reis, Samuel; Santos, João A.The grapevine vegetative cycle, which is morphologically described by its phenological stages, is strongly determined by weather conditions. Phenological models are widely applied in viticulture and are based on the assumption that air temperature is the preponderant environmental factor which determines vine development. In this study, phenological development models (PDMs) were calibrated and validated to simulate several intermediate stages between budbreak and veraison for cv. Touriga Nacional (TN) and cv. Encruzado (EN) winegrape varieties, which are widely grown in the Dao Wine Region, Portugal. These are thermal models, with which the daily sum of the rate of forcing (R) was calculated using a sigmoid function. For this purpose, a high-quality and comprehensive dataset was used which combines phenology data and weather station data in several vineyard sites spread over the region. The model showed an overall high performance (global RMSE of 5.4 days for EN and 5.0 days for TN), although it depended on the phenological stage and variety. The RMSE ranged from 3.2 to 6.2 for TN, and from 3.9 to 6.8 for EN. For both varieties and in all phenological stages, the RMSE was significantly lower than the standard deviation of the phenological observations. For TN, the model efficiency was greater than 0.71 for all phenological stages. In future studies, these models will be combined with specific models that simulate the evolution of winegrape berry quality indicators commonly used for harvest decision support. The relatively low complexity of the selected PDMs enables their use as a crop management and decision support tool. To our knowledge, no previous studies have been carried out on either of these two varieties and their intermediate phenological timings. The present study is an illustration of conceivable model development under diverse environmental conditions, thus allowing similar approaches to be adopted in other wine regions on a worldwide scale.
- Are Consumers Aware of Sustainability Aspects Related to Edible Insects? Results from a Study Involving 14 CountriesPublication . Guiné, Raquel P. F.; Florença, Sofia De Guiné E; Anjos, Ofélia; Boustani, Nada M.; Chuck-Hernández, Cristina; Sarić, Marijana Matek; Ferreira, Manuela; Costa, Cristina Amaro Da; Bartkiene, Elena; Cardoso, Ana Paula; Tarcea, Monica; Correia, Paula; Campos, Sofia; Papageorgiou, Maria; Camino, Daniel Abarquero; Korzeniowska, Malgorzata; Černelič-Bizjak, Maša; Kruma, Zanda; Damarli, Emel; Ferreira, Vanessa; Djekic, IlijaIn recent years, edible insects have been suggested as an alternative food that is more sustainable compared with other sources of animal protein. However, knowledge about the sustainability aspects associated with this source of food may play a role in convincing consumers to adopt insects as part of their diet. In this context, the present study investigated the level of knowledge about the sustainability of edible insects in a group of people originating from 14 countries, with some naturally entomophagous and others not. To measure the knowledge, 11 items were selected and the scores obtained were tested with statistical tools (t-test for independent samples, analysis of variance—ANOVA) to search for differences according to sociodemographic and socioeconomic characteristics, geographical origin, and consumption habits of edible insects. The obtained results showed that, in general, knowledge is moderate, with the values of the average scores for the 11 items investigated ranging from 0.23 ± 0.99 to 0.66 ± 1.02, on a scale ranging from –2 (=very low knowledge) to 2 (=very high knowledge). The highest scores were found for items relating to the lower use of animal feed and lower emission of greenhouse gases required for the production of insects compared with beef. When investigating the differences between groups of participants, significant differences were generally found, revealing a trend for higher knowledge among males and young adults, for participants residing in urban areas and in countries such as Spain, Mexico, and Poland, and for participants with higher education levels and higher incomes. When testing the influence of consumption variables on the level of knowledge, the results showed a higher knowledge for participants who had already consumed insects or are willing to consume them. Finally, it was observed that higher knowledge was found for participants whose motivation to consume insects related to curiosity, a wish to preserve the planet, the gastronomic characteristics of insects, and their nutritional value. In conclusion, these results clearly indicate a very marked influence of a number of variables on the knowledge about the sustainability of edible insects, and this may be helpful to delineate strategies to effectively raise knowledge and eventually increase the willingness to consider insects as a more sustainable alternative to partially replace other protein foods, even in countries where this is a not a traditional practice.
- Let Games Begin and Go onPublication . Matos, Maria Cristina P.; Ferreira, Manuel Alberto M.; Filipe, José AntónioReal life is a bigger game in which what a player does early on can affect what others choose to do later on. In particular, we can strive to explain how cooperative behaviour can be established as a result of rational behaviour. When engaged in a repeated situation, players must consider not only their short-term gains but also their long-term payoffs. The general idea of repeated games is that players may be able to deter another player from exploiting his short-term advantage by threatening a punishment that reduces his long-term payoff. The aim of the paper that supports this abstract is to present and discuss dynamic game theory. There are three basic kinds of reasons, which are not mutually exclusive, to study what happens in repeated games. First, it provides a pleasant and a very interesting theory and it has the advantage of making us become more humble in our predictions. Second, many of the most interesting economic interactions repeated often can incorporate a phenomenon which we believe are important but which are not captured when we restrict our attention to static games. Finally, economics, and equilibrium-based theories more generally, do best when analysing routinised interactions. Copyright © 2018 Inderscience Enterprises Ltd.
- Spontaneous Fluctuations between Diagnostic and Nondiagnostic ECGs in Brugada Syndrome Screening: Portuguese Family with Brugada SyndromePublication . Santos, Luis Ferreira dos; Correia, Emanuel; Rodrigues, Bruno; Nunes, Luis; Costa, António; Carvalho, José Lopes; Elvas, Luis; Henriques, Carla; Matos, Ana; Santos, Jorge OliveiraBACKGROUND: All family members of patients with Brugada syndrome (BS) should be screened. Fluctuations between diagnostic and nondiagnostic electrocardiogram (ECG) patterns in patients with BS are recognized, but systematic studies are lacking. The objective of this work was to prospectively evaluate the spontaneous changes between diagnostic and nondiagnostic ECG patterns in a family screened for BS. METHODS: One hundred twenty-nine family members were possibly affected plus the index case were screened with two ECGs with an interval of 6 months. Only coved-type ECG pattern was defined as diagnostic; type 2 and 3 ECGs were considered suggestive. RESULTS: The first ECG series made six diagnostics and the second 11, but only three patients maintained the diagnostic ECG. Patients with basal diagnostic ECG were older and more frequently symptomatic. Body mass index (BMI) was significantly lower in adults with diagnostic plus suggestive ECG when compared with the others. No significant gender difference was found among relatives with or without diagnostic ECG. CONCLUSION: Spontaneous phenotypic manifestation of BS was more frequent in older symptomatic patients, absent in children, and related with low BMI. ECG manifestations were intermittent in more than 3/4 of the affected patients. Fluctuations between diagnostic and nondiagnostic ECGs may have an implication on the correct phenotyping in family screening so several ECGs with drug challenging are mandatory.
- A closer look at Santiago de Compostela's pilgrims through the lens of motivationsPublication . Amaro, Suzanne; Antunes, Angela; Henriques, CarlaThis study aims to identify pilgrims’ motivations to undertake the Camiño de Santiago and examine differences regarding socio demographics and other characteristics. An online questionnaire was used to collect data from pilgrims that had travelled the Camiño de Santiago. A total of 1,140 valid responses was collected from 45 different nationalities. The results indicate that pilgrims are mostly motivated by spiritual aspects, by wanting new experiences and for the nature and sports experience. Interestingly, religious motivations are the least important. The study also found that motivations differ according to several factors such as gender, nationality and the way the pilgrims undertook their journey. The findings of this study offer a better understanding of modern pilgrims, providing useful insights to stakeholders.
