- Brand hate semiotics: hate as a story theory. Netnographic approach during the war on GazaPublication . Assoud, Mohamed; Berbou, Lahoucine; Vieira, Luís SérgioPurpose – This study aims to investigate brand hate semiotics among Muslim and Arabic-speaking consumers during the 2023 war on Gaza, exploring traits associated with hated and boycotted brands within a sociopolitical context. Design/methodology/approach – The research uses semiotic analysis and a netnographic approach to examine 3,000 public consumer-generated content linked to the hashtag # عطاق) boycott in Arabic) from Instagram and Facebook. Findings – Brands such as McDonald’s, KFC, Coca-Cola and Starbucks, which were subjected to hate and boycotts, are linked to negative associations and narratives, including The Stranger, The Faceless Foe, The Enemy of God and The Criminal. User-generated content significantly influences brand boycotts among Muslim and Arabic-speaking consumers. Research limitations/implications – Future research should explore additional sociopolitical contexts and demographics to generalize the findings further. Practical implications – Understanding the semiotic drivers of brand hate can help marketers develop effective crisis management and brand recovery strategies tailored to specific cultural contexts. Social implications – The findings highlight the impact of sociopolitical events on consumer behavior, emphasizing the need for brands to be aware of their cultural and ethical stances in global markets. Originality/value – This research contributes to brand hate theory by using the “hate as a story” lens, offering a unique theoretical perspective. It systematically explores the semiotic aspects of brand hate and pioneers’ semiotic analysis and netnography in this field. The study also addresses the underrepresentation of Muslim and Arabic-speaking consumers in brand hate literature.
- Decent work research in tourism industry: a bibliometric mappingPublication . Faria, Liliana; Gouveia, Cláudia; Florêncio, LuísAbstract: The study of decent work in tourism is critical to ensure the sustainable growth of the industry, workers’ rights are respected, and local communities as well as tourists benefit. To this end, we conducted a bibliometric analysis of research on decent work in tourism. The analysis covered 105 studies from the Scopus database. VOSviewer was used to perform a citation, bibliographic linkage, co-citation, and co-occurrence analysis. The increase in the number of research papers and citations on this topic shows that it has progressively attracted the attention of researchers in the last three years. Results show that the United Kingdom is the most productive country in this field of study while the journal with the greatest influence is Journal of Sustainable Tourism. The study with the strongest link to other publications is “Rethinking decent work: the value of dignity in tourism employment”. The most studied topics concern the integration of decent work to achieve Sustainable Development Goals in the context of sustainable tourism and the sustainable adaptation of the hospitality and tourism industry in the time of COVID -19. Future research directions are also outlined.
- A deep regression model with low-dimensional feature extraction for multi-parameter manufacturing quality predictionPublication . Deng, Jun; Bai, Yun; Li, ChuanManufacturing quality prediction can be used to design better parameters at an earlier production stage. However, in complex manufacturing processes, prediction performance is a_ected by multi-parameter inputs. To address this issue, a deep regression framework based on manifold learning (MDRN) is proposed in this paper. The multi-parameter inputs (i.e., high-dimensional information) were firstly analyzed using manifold learning (ML), which is an e_ective nonlinear technique for low-dimensional feature extraction that can enhance the representation of multi-parameter inputs and reduce calculation burdens. The features obtained through the ML were then learned by a deep learning architecture (DL). It can learn su_cient features of the pattern between manufacturing quality and the low-dimensional information in an unsupervised framework, which has been proven to be e_ective in many fields. Finally, the learned features were inputted into the regression network, and manufacturing quality predictions were made. One type (two cases) of machinery parts manufacturing system was investigated in order to estimate the performance of the proposed MDRN with three comparisons. The experiments showed that the MDRN overwhelmed all the peer methods in terms of mean absolute percentage error, root-mean-square error, and threshold statistics. Based on these results, we conclude that integrating the ML technique for dimension reduction and the DL technique for feature extraction can improve multi-parameter manufacturing quality predictions.
- Determinants of consumers’ acceptance and adoption of novel food in view of more resilient and sustainable food systems in the EU: a systematic literature reviewPublication . Laureati, Monica; De Boni, Annalisa; Saba, Anna; Lamy, Elsa; Minervini, Fabio; Delgado, Amélia; Sinesio, FiorellaThis review article aims to provide an up-to-date overview of the main determinants of consumers’ acceptance of novel foods (new foods and ingredients) in the EU with emphasis on product’s intrinsic properties (sensory characteristics) and individual factors (socio-demographics, perceptive, psychological) by adopting a systematic approach following the PRISMA methodology. Case studies on terrestrial (i.e., insects, cultured meat and other animal origin products, plantbased food including mushrooms, plant-based analogues, pulses, and cereals) and aquatic systems (i.e., algae and jellyfish) are included focusing on age-related and cross-national differences in consumer acceptance of novel foods and ingredients. General trends have emerged that are common to all the novel foods analysed, regardless of their aquatic or terrestrial origin. Aspects such as food neophobia, unfamiliarity, and poor knowledge of the product are important barriers to the consumption of novel foods, while healthiness and environmental sustainability perception are drivers of acceptance. Sensory properties are challenging for more familiar ingredients such as plant-based food (e.g., novel food made by pulses, mushrooms, cereals and pseudocereals). Results are discussed in terms of feasibility of introducing these products in the EU food systems highlighting strategies that can encourage the use of new ingredients or novel foods.
- First-year higher education student environmental literacy – the Algarve University casePublication . Oliveira Campos, Clarice; Silva Fernandes, Maria Jacinta; Gonçalves, Gabriela; Sousa, Cátia; Spínola, HélderThe study aims to contribute to characterizing the environmental literacy profile of students entering higher education in Portugal and to explore associations between sociodemographic variables and environmental knowledge, attitudes, and behavior. A questionnaire survey was conducted with a stratified sample of 451 first-year undergraduate students from the University of the Algarve (southern Portugal). Results suggest that students demonstrated moderate environmental knowledge, positive attitudes toward the environment, and moderately positive pro-environmental behaviors. Evidence of relationships between students' environmental literacy profiles and sociodemographic aspects such as gender and scientific areas of study provides insights for future discussions and promotion of environmental education and culture in higher education institutions in Portugal. This will enable them to play an effective role in enhancing students' environmental literacy and citizenship.
- An overview of mindfulness theories applied to tourism: systematic review update and bibliometric analysisPublication . Iacob, Vivien; Neves de Jesus, Saúl; Carmo, CláudiaThis paper presents a systematic review update regarding mindfulness theories applied to tourism, complemented with a bibliometric analysis. Scientific studies listed in the WOS, SCOPUS, PubMed and PsycInfo databases were analysed using PRISMA guidelines. Twenty-five studies were selected for review from 670 records identified. In recent years, mindfulness has proved to be a promising area of research in tourism, and the number of published studies is increasing. The findings reveal a positive association between mindfulness and tourism experiences, suggesting that tourists who adopt states of mindfulness during their travels benefit from increased pro-environmental behaviours, satisfaction levels, and memorable experiences, leading to destination loyalty. This study provides an in-depth overview of the literature, and helps redress the lack of bibliometric studies in this field. It also identifies common areas of current research interest, offers insights into commonly studied themes, and seeks to raise awareness about the relevance of the concept of mindfulness in tourist experiences and well-being by suggesting implications for research and tourism management.
- Travel motivation and well-being: analysing the mediating role of mindfulness and memorable travel experiences of portuguese travellersPublication . Iacob, Vivien; Neves de Jesus, Saúl; Garcês, Soraia; Carmo, CláudiaThere is a common perception that tourism can directly or indirectly enhance well-being. The travellers' motivations could influence the connection between tourism and well-being. This study aimed to examine the relationship between travel motivations and well-being and the beneficial effects of mindfulness and memorable travel experiences (MTEs) on this relationship. The data were gathered using online questionnaires and included 256 participants. The findings suggested that travel motivation positively influenced well-being, mindfulness, and MTEs. The mediating role of MTEs and mindfulness in the relationship between motivation and well-being was verified. In conclusion, this study emphasises the importance of comprehending the influence of travel motivations, mindfulness, and MTEs in promoting and enhancing well-being. Understanding the psychological variables affecting well-being is crucial for researchers and tourism managers to incorporate effective methods for better management and marketing, considering that tourism offers are more suited to consumer demand.
