- Ascertaining Restaurant Financial Sustainability by Analyzing Menu PerformancePublication . Gomes, Conceição; Malheiros, Cátia; Lima Santos, Luís; Campos, Filipa Alexandra Gomes deThe complexity of companies in the restaurant industry is clear, and various techniques can be used to make decisions. The analysis of performance and the optimization of restaurant menus are considered important, which is why several approaches can be used. The objective of this study is to achieve financial sustainability in the restaurant industry through menu performance analysis and identifying strategies to improve menu profitability. A qualitative methodology of a dual case study was adopted by comparing a restaurant within a hotel and a street restaurant. The results show that for restaurant owners and managers, these approaches are useful, simple, and pertinent for measuring the performance of the restaurant menu and consequently improving results. The originality of this research lies in the fact that three analysis models were applied simultaneously, allowing for an in-depth analysis of the profitability of the menus being analyzed. This study identified the most profitable items for each restaurant and the items that needed to be changed to contribute more to the profitability of the restaurant’s menu, resulting in practical implications. Through theoretical implications, this study corrects the limited knowledge about performance through the restaurant menu, creating a starting point for knowledge spreading to society. In conclusion, this research is one of the first to bridge the gap between theory and practice, taking several approaches to assess restaurant menu performances, which can be useful in restaurants to promote sustainability.
- Bibliometric Analysis of the Scientific Production in Cultural Tourism from 2010 to 2019 in EuropePublication . Caicedo Barreth, Alba; Santos Pavón, Enrique; Lima Santos, LuísThis paper provides a general review of cultural tourism as a research subject in the last decade in Europe. First, it defines the terminology and its dimensions. This is followed by the analysis of the scientific papers published in international journals between 2010 and 2019, available in the Web of Science (WoS) and Scopus databases, to ensure the inclusion of high-impact studies according to the bibliometric quality index. Through the quantitative analysis of 625 WoS articles and 765 Scopus articles using bibliographic coupling, co-citation and co-occurrence analysis, this publication provides a significant overview of the terms involved or related to cultural tourism and the proposed clustering for each term. This paper concludes with a discussion of the main trends identified, their characteristics and possible changes over time
- Characterization of Selected Wild Mediterranean Fruits and Comparative Efficacy as Inhibitors of Oxidative Reactions in Emulsified Raw Pork Burger PattiesPublication . Ganhão, Rui; Estévez, Mario; Kylli, Petri; Heinonen, Marina; Morcuende, DavidIn the present study, water, ethanolic, and methanolic extracts from seven selected wild fruits originally from the Mediterranean area, namely, strawberry tree (Arbutus unedo L., AU), azarole (Crataegus azarolus L., CA), common hawthorn (Crataegus monogyna L., CM), blackthorn (Prunus spinosa L., PS), dog rose (Rosa canina L., RC), elm-leaf blackberry (Rubus ulmifolius Schott, RU), and rowan (Sorbus aucuparia L., SA), were analyzed for the total amount and profile of phenolic compounds and for the in vitro antioxidant activity against the DPPH and ABTS radicals (study 1). The seven fruits showed different chemical compositions, which consequently led to different antioxidant potentials. Among the seven fruits initially analyzed, AU, CM, RC, and RU had the highest amount of phenolic compounds and displayed the greatest antioxidant activity in vitro. Extracts from these four fruits were tested as inhibitors of lipid oxidation in raw pork burger patties subjected to refrigerated storage at 2 °C for 12 days (study 2). The quantitative measurements of thiobarbituric acid reactive substances (TBA-RS), hexanal content, and color stability were used as indicators of oxidative reactions. The four selected fruits displayed intense antioxidant activity against lipid oxidation, which highlights the potential usage of these fruits as ingredients for the manufacture of healthy meat products. Among them, RC and AU were particularly efficient as their protective effect against lipid oxidation was more intense than that displayed by quercetin (230 mg/kg of burger patty).
- Destination Brand Experience: A Study Case in Touristic Context of the Peneda-Gerês National ParkPublication . Martins, Hugo; Carvalho, Paulo; Almeida, NunoBased on the scientific literature, this paper emphasises the destination brand experience (DBE) (multidimensional construct and second-order factor) in order to analyse the implications it plays regarding visitors’ satisfaction, their intentions to revisit and their intentions to recommend it. In terms of methodology, a confirmatory factor analysis was used to test the model and the research hypotheses. The sample was composed of 507 tourists who visited the Peneda-Gerês National Park in Northern Portugal. Results showed an acceptable fit. The items of each construct were very strong. Positive significant results were found for all the considered hypotheses, particularly regarding the association of sensory DBE and behavioural DBE (subdimensions of the DBE scale) with satisfaction. The sensory DBE and affective DBE subdimensions of the DBE scale were meaningfully associated with visitors’ intentions to recommend. Satisfaction was a strong mediator for sensory DBE impact on their intention to revisit and to recommend, and a less strong effect was found for satisfaction as a mediator for behavioural DBE impact on intentions to revisit and to recommend. The theoretical contribution of this study aimed to deepen the analysis of the DBE construct in its multidimensional aspect and its relationship with other constructs. The results are discussed in relation to their theoretical and practical relevance.
- Diel vertical behavior of Copepoda community (naupliar, copepodites and adults) at the boundary of a temperate estuary and coastal watersPublication . Gonçalves, A.M.M.; Pardal, M.A.; Marques, S.C.; S. Mendes; M.J. Fernández-Gómez; M.P. Galindo-Villardón; U.M. AzeiteiroDespite a growing interest in diel vertical migration as a research topic, there are few studies in southern European marine coastal systems. This study determined the main structuring hydrological and physical factors at different temporal scales in copepod assemblage distribution patterns. Seasonal, tidal, lunar and diel vertical migrations accomplished by horizontal movements were examined on the main copepod fraction of the Mondego estuary, Portugal. Seasonal samples were conducted hourly at the mouth of the estuary, during diel cycles (25h), both over neap and spring tides, at the bottom and surface, using a 63μm and 335μm mesh size nets. Simultaneously, four sites inside the estuary were sampled during flood tide to evaluate and compare copepods species' distribution along the estuary. Species life cycles were also categorized. Spring-spring tide best expresses the stable part of copepod-environment dynamics. Acartia tonsa and Oithona nana were distributed mainly at the bottom during ebb tides. A clear resident estuarine performance was noticeable in O.nana proving the estuarine preferences of the species. Neritic species showed preferences by saline waters, whereas the resident species were found mainly at estuarine areas. Copepodites stages showed a similar distribution pattern as estuarine species, avoiding leaving the estuary. In contrast nauplii and Oithona plumifera showed higher densities at surface flood tides. Indeed, vertical migrations accomplished by horizontal movements were mainly influenced by depth and tidal cycles, whereas day and night were not ecologically significant.
- Discovering the Dynamics and Impact of Motorcycle Tourism: Insights into Rural Events, Cultural Interaction, and SustainabilityPublication . Monteiro, Anabela; Lopes, Sofia; Carmo, Manuel DoThis study explores the dynamics of motorcycle tourism in rural areas and its potential contribution to sustainable and regenerative development. A bibliometric analysis of management-related publications was conducted using the Web of Science Core Collection, focusing on topics such as tourism, motivation, rurality, and motorcycling. VOSviewer software (version 1.6.20) was employed to support this analysis. Based on the literature, a theoretical framework was developed, leading to four research hypotheses that aimed to empirically examine the relationships between cultural motivation, community interaction, type of accommodation, event location, and tourist behaviour. To test these hypotheses, structured questionnaires were distributed in person during rural motorcycling events in Portugal, yielding a valid sample of 233 respondents. The data were analysed using SPSS 28 software via statistical methods to reduce dimensionality and identify latent structures, chi-square tests, and logistic regression. The results confirmed all four hypotheses, highlighting the importance of cultural motivation for return intentions, community interaction for perceived authenticity, accommodation type for destination recommendations, and event location for overall satisfaction. The study also identifies gender-related differences and reinforces the value of immersive, co-created experiences in enhancing the competitiveness of rural destinations. This theoretical contribution supports the advancement of motorcycle tourism as a sustainable niche while offering practical guidance for inclusive and regenerative tourism planning.
- An empirical comparison of Canonical Correspondence Analysis and STATICO in the identification of spatio-temporal ecological relationshipsPublication . Mendes, Susana; Fernández-Gómez, M. José; Pereira, Mário Jorge; Azeiteiro, Ulisses Miranda; Galindo-Villardón, M. PurificaciónThe wide-ranging and rapidly evolving nature of ecological studies mean that it is not possible to cover all existing and emerging techniques for analyzing multivariate data. However, two important methods enticed many followers: the Canonical Correspondence Analysis (CCA) and the STATICO analysis. Despite the particular characteristics of each, they have similarities and differences, which when analyzed properly, can, together, provide important complementary results to those that are usually exploited by researchers. If on one hand, the use of CCA is completely generalized and implemented, solving many problems formulated by ecologists, on the other hand, this method has some weaknesses mainly caused by the imposition of the number of variables that is required to be applied (much higher in comparison with samples). Also, the STATICO method has no such restrictions, but requires that the number of variables (species or environment) is the same in each time or space.Yet, the STATICO method presents information that can be more detailed since it allows visualizing the variability within groups (either in time or space). In this study, the data needed for implementing these methods are sketched, as well as the comparison is made showing the advantages and disadvantages of each method. The treated ecological data are a sequence of pairs of ecological tables, where species abundances and environmental variables are measured at different, specified locations, over the course of time.
- Employer Branding Applied to SMEs: A Pioneering Model Proposal for Attracting and Retaining TalentPublication . Monteiro, Beatriz; Santos, Vasco; Reis, Isabel; Sampaio, Marta Correia; Sousa, Bruno; Martinho, Filipa; Sousa, Maria José; Au-Yong-Oliveira, ManuelMost business enterprises are small and medium-sized enterprises (SMEs), and many of them are without a human resource and recruitment department. Thus, one of the challenges that organizations currently face is to find a strategy to retain and attract talent. To overcome this difficulty, enterprises must invest in employer branding policies and be aware of the factors that differentiate them from others when attracting employees. This study aims to develop an employer branding model applicable to SMEs, to increase and enhance the attraction and retention of talents. An exploratory approach based on a quantitative perspective was adopted to develop an employer branding model applied to SMEs, with two major reference employer branding models and frameworks used as the main support. The model of employer branding was applied to SMEs regarding four dimensions, whereby essential questions are asked, namely (1) organizational culture (e.g., do employees have a job description aligned with the corporate culture?), (2) company strategy (e.g., what is the strategy if business volume decreases?), (3) company reputation (e.g., how do you perceive and treat negative feedback?), and (4) reward systems (e.g., do you feel that your employees are motivated intrinsically or extrinsically or both?), ordered by layers based on a logical sequence. The new proposed model is expected to serve as a useful strategic tool and as a basis for attracting, retaining and managing talent, specifically in the SMEs context. This new model provides a set of strategic and competitiveness benefits for SMEs, while contributing to making enterprises more profitable. The model also contributes to SMEs having a better image and reputation, enabling them to stand out from others in the war for talent.
- Factors Influencing Hotel Revenue Management in Times of Crisis: Towards Financial SustainabilityPublication . Lima Santos, Luís; Gomes, Conceição; Malheiros, Cátia; Crespo, Catarina; Bento, Carla(1) Background: Facing the challenges of a post-pandemic period and the Ukraine War and recognising the gap in scientific research on the application of revenue management (RM) in the Portuguese hotel industry, the main objective of this study is to identify the most effective and least appropriate RM practices for use in periods of low demand and crises, reflecting the financial sustainability perspective. The theoretical framework of this study focuses on the main RM practices, grouping them into price and non-price strategies. (2) Methods: A quantitative methodology was employed, collecting information from Portuguese hotels through an online questionnaire, and statistical analysis using Mann–Whitney and Chi-square tests was conducted. (3) Results: Hotels offered discounts during the pandemic, but room rates were reduced during the recovery period. These findings also revealed that commonly used techniques were the best available rate (BAR) and rate fences, particularly during the pandemic. Quality, brand image, strategic partnerships, and marketing actions are recognised as essential. However, loyalty programs, length of stay (LOS) control, rate parity, and bundled services are not commonly implemented despite their importance during periods of low demand. Larger hotels, five-star hotels, and members of international chains applied more RM practices than smaller four-star independent hotels. (4) Originality: This study provides original and valuable insights into increasing hotel revenues and occupancy rates during future periods of low demand, which benefit financial sustainability.
- Feeding habits of Solea senegalensis in earthen ponds in Sado estuaryPublication . Castelo Branco, Maria Ana; Arruda, Marco A.; Gamito, SofiaThe senegale sole, Solea senegalensis Kaup, 1858, is a commercially valuable fish and it is beginning to be cultured in a semi-intensive way in fish farms in southern European countries. The present study was initiated to investigate the diet of S. senegalensis under semi-extensive conditions. The feeding habits of sole were studied in two earthen ponds of a fish farm in the Sado estuary. In one earthen pond, artificial fish ration was given. S. senegalensis feeds on few prey items, its diet is mainly composed of insect larvae (Chironomus salinarus) and polychaeta (Hediste diversicolor). The diet composition of this species suggests feeding specialization, by consuming mainly annelids and insect larvae and by avoiding other items, extremely abundant in the environment, such as gastropods. In the water reservoir where ration was given, some fish consumed simultaneously benthic organism together with ration. However, benthic organisms seem to be the most important component of S. senegalensis diet.
