Body and Mind in Virtual Dark Tourism Experiences and Artwork Creations: Embodied Cognition Reaction Perspectives
Authors: Santoso Halim Budi , Quarshie Benjamin , Ukpabi Dandison , Wang Jyun-Cheng 
Published: May 2024

AbstractDark tourism experiences visualized in destinations evoke diverse tourist experiences, triggering negative emotions and offering insights into historical events. Embodied cognition reactions prompt distinct expressions, reflections, and artwork creation, which can leverage Virtual Reality in tourism and augment dark experiences for distant tourists. This study examines embodied cognition reactions in virtual dark tourism with 32 participants, investigating their responses to narratives and auditory stimuli while impacting artwork. Results show amplified affective experiences via added auditory stimuli and cognitive experiences influenced by narratives. Post-experience, participants manifest their encounters in artworks, reflecting body-mind links.

Published: May 2024

AbstractThe rapid advancement of Virtual Reality (VR) technologies, bolstered by cutting-edge hardware, has ushered in a new era that blurs the lines between the physical and virtual realms. As opportunities for immersive information absorption in virtual worlds grow, the tourism industry faces escalating pressure to stay competitive. Although traditional VR mainly engages audio-visual senses, this study examines whether multisensory VR in the pre-travel phase enhances users’ sense of presence and technology acceptance. Employing a mixed-methods, between-subjects design, we conducted an experiment with 103 participants divided into a multisensory VR group and an audio-visual VR group. Our aim was to investigate the impact on the sense of ’being there,’ technology acceptance, and the relationship between increased presence and acceptance. Results from tourism professionals reveal no significant variation in physical presence between the two groups; however, the multisensory VR group showed a notable difference in self-presence. Our findings suggest that the inclusion of multisensory stimuli makes VR more approachable and user-friendly, leading to greater self-presence and technology acceptance.

Authors: Flavián Carlos , Ibáñez-Sánchez Sergio , Orús Carlos 
Published: May 2024

AbstractThe metaverse is currently highlighted as one of the technologies with the greatest potential, particularly in the tourism industry. Despite this fact, most of the research on this topic has been of a conceptual nature. This research aims to contribute to this nascent research field by analyzing how the use of the metaverse for viewing a museum can influence the different dimensions of the customer experience. For this purpose, the degree of technological embodiment of the device, as well as the presence (or not) of other users in the digital environment, will be taken into account. Two focus groups were conducted to explore this matter. The results bring to light the importance of the affective and cognitive states that customers feel when they are in the museum through the metaverse. In addition, participants indicate that they prefer to experience the metaverse museum with other people, noting that this closeness to other users may be greater when embodied technologies are applied. This research contributes empirically to this field of research by trying to delineate how the museum experience should be constructed to offer value through the metaverse.

Sustainability Nudges While Booking a Flight on an OTA Website
Authors: Stüben Jannina Maleika , Cantoni Lorenzo 
Published: May 2024

AbstractIn recent years the ecological impact of Tourism has been more and more considered, raising the issue of how to ensure higher levels of sustainability. Especially when it comes to flights, the issue of energy consumption and of exploring strategies to reduce the CO2 footprint of civil aviation has attracted a special attention, in particular while taking into account the so-called attitude-behavior gap, which describes major discrepancies between what people say about their commitment to sustainability and what they actually do when taking decisions. A possible strategy to address such issues is leveraging on “nudges” while persons are exploring available flights on an online travel agency’s platform (OTA), ensuring that they are adequately informed and offered good – more sustainable – alternatives. Based on the current literature and on the analyzed cases, this study presents a first map of twelve possible types of nudges, organized in four main categories: CO2 emissions, transportation mode, CO2 compensation, and sustainability efforts. Moreover, it shows their actual, quite limited, presence on ten major OTAs.
Against Social Sustainability? Gender Role Models and Tourism Influencers’ Success on Instagram
Authors: Gewinner Irina V. 
Published: May 2024

AbstractThis paper examines the phenomenon of influencers with a special focus on the tourism industry. The question arises whether self-portrayal within a gender-stereotypical framework correlates positively with success and the number of followers. To this end, the profiles of twelve tourism influencers and their posted content in the first half of 2023 were analyzed. With the help of quantitative content analysis, we examined 427 photos of tourism influencers on the Instagram platform. The results show that while female tourism influencers more often present themselves in a sexualized way and focus on themselves and their bodies, male tourism influencers put their competencies in the foreground. In this way, both female and male influencers comply with their expected gender roles – in addition to the body, a presentation of socially expected actions and attributes is also in the foreground. The results are discussed against the background of social sustainability.
A Closer Look of Revenge Travelers

Published: May 2024

AbstractThis study investigated how three different types of revenge travel - more expensive trips, longer stays, and more frequent travel - are affected by the combination of consumers’ perceived constraints, negotiation, and compromises. Using fuzzy-set qualitative comparative analysis (fsQCA) on a sample of 500 survey responses, this study identified similar and distinctive patterns for each type of the revenge travel. By enhancing our understanding of the revenge travelers across different types, this study offers insights for industry managers and policymakers in developing better strategies to facilitate recovery in tourism following a crisis.

Authors: Fan Daisy X. F. , Lyu Jiaying , Huang Yi , Shang Kaiti , Buhalis Dimitrios 
Published: May 2024

AbstractAs with the development of digital technology, increasing older adults have used digital technologies in different stages of their travel. While advocating the positive aspects of digital usage among older adults, the downside has been largely neglected. Moreover, older adults vary in their backgrounds, lifestyles, digital competence and specific needs. When seeking appropriate solutions to enhance their digital travel experience, it is important to initially profile the diverse subgroups and delineate their specific preferences. This study adopted a humanisation perspective and a qualitative approach to 1) understand senior tourists’ digital travel experience, 2) explore senior tourists’ needs and requirements regarding digital travel, and 3) develop a senior tourists’ digital travel experience typology. Findings provide rich contributions in understanding senior tourists’ digital use and the humanised digital travel experience. Recommendations are also offered to destinations, tourism service providers and care providers regarding how to develop an age friendly destination digital environment.
An Empirical User Study on Congestion-Aware Route Recommendation

Published: May 2024

AbstractOvertourism has become a significant concern in many popular travel destinations around the world. As one of considerable approaches to handle the overtourism issues, congestion-aware methods can be effective in mitigating overcrowding at popular attractions by spreading tourists to less-visited areas. However, they may lead to a potential Hawk-Dove game: tourists who share the same preference may have some of them assigned worse routes than others to avoid congestion, which raises a possibility that the tourists who are assigned to relatively unfavorable routes may feel dissatisfaction and unfairness. Most existing research focuses on alleviating congestion from an overall planner perspective through simulation studies, with little emphasis on actual user experience. In this study, we conducted a user survey on congestion-aware route recommendation in Kyoto, Japan, aiming to investigate the evaluation of congestion-aware route recommendation methods from each tourist’s personal perspective and to clarify the development status and future research directions of congestion-aware route recommendation methods. We choose five congestion-aware route recommendation methods that vary in their consideration of congestion and multi-agent interactions. We reveal the strengths and weaknesses of these methods from multiple aspects. We cluster the respondents based on their text responses and explore the differences between these clusters. Furthermore, we investigate the factors affecting tourists’ experience and compare the differences among groups of tourists.
Visualizing Explainable Touristic Recommendations: An Interactive Approach
Authors: Neubig Stefan , Cappey Daria , Gehring Nicolas , Göhl Linus , Hein Andreas , Krcmar Helmut 
Published: May 2024

AbstractPersonalized recommendations have played a vital role in tourism, serving various purposes, ranging from an improved visitor experience to addressing sustainability issues. However, research shows that recommendations are more likely to be accepted by visitors if they are comprehensible and appeal to the visitors’ common sense. This highlights the importance of explainable recommendations that, according to a previously specified goal, explain an algorithm’s inference process, generate trust among visitors, or educate visitors by making them aware of sustainability practices. Based on this motivation, our paper proposes a visual, interactive approach to exploring recommendation explanations tailored to tourism. Agnostic to the underlying recommendation algorithm and the defined explainability goal, our approach leverages knowledge graphs to generate model-specific and post-hoc explanations. We demonstrate and evaluate our approach based on a prototypical dashboard implementing our concept. Following the results of our evaluation, our dashboard helps explain recommendations of arbitrary models, even in complex scenarios.
Understanding Users’ Perceptions of Travel Accounts on Instagram: Comparing DMO and Travel Influencer Accounts
Authors: Neuburger Larissa , Barbe Danielle , Fedeli Giancarlo 
Published: May 2024

AbstractSocial Media has become an important marketing tool for destinations due to its easy access, ability to reach broad audiences and capacity to act as a form of eWOM. Instagram in particular is one of the most popular channels for the visual marketing of a destination as well as for influencer marketing. Through Instagram, DMOs can create travel inspiration, and enhance interest in a destination. This study seeks to understand the tourists’ perceptions of Instagram influencers as well as official DMO accounts and looks on their influence on tourists’ participation and engagement on social media. A quantitative survey was conducted to analyze users’ perceptions of DMO and influencer accounts on Instagram, as well as their participation behavior online. The study found that DMOs are perceived as being more trustworthy and credible than travel influencers. In addition, results indicate that active Instagram users are more likely to have positive perceptions of travel influencers, but online participation does not influence perceptions of DMOs.
LPS-induced monocarboxylate transporter-1 inhibition facilitates lactate accumulation triggering epithelial-mesenchymal transformation and pulmonary fibrosis

Published: May 2024

AbstractThe epithelial-mesenchymal transformation (EMT) process of alveolar epithelial cells is recognized as involved in the development of pulmonary fibrosis. Recent evidence has shown that lipopolysaccharide (LPS)-induced aerobic glycolysis of lung tissue and elevated lactate concentration are associated with the pathogenesis of sepsis-associated pulmonary fibrosis. However, it is uncertain whether LPS promotes the development of sepsis-associated pulmonary fibrosis by promoting lactate accumulation in lung tissue, thereby initiating EMT process. We hypothesized that monocarboxylate transporter-1 (MCT1), as the main protein for lactate transport, may be crucial in the pathogenic process of sepsis-associated pulmonary fibrosis. We found that high concentrations of lactate induced EMT while moderate concentrations did not. Besides, we demonstrated that MCT1 inhibition enhanced EMT process in MLE-12 cells, while MCT1 upregulation could reverse lactate-induced EMT. LPS could promote EMT in MLE-12 cells through MCT1 inhibition and lactate accumulation, while this could be alleviated by upregulating the expression of MCT1. In addition, the overexpression of MCT1 prevented LPS-induced EMT and pulmonary fibrosis in vivo. Altogether, this study revealed that LPS could inhibit the expression of MCT1 in mouse alveolar epithelial cells and cause lactate transport disorder, which leads to lactate accumulation, and ultimately promotes the process of EMT and lung fibrosis.

Published: May 2024

AbstractMaking furniture or furniture elements that account for the needs of children at various stages of development or with psychomotor dysfunctions is very difficult. From the point of view of exploitation and production technology, it is difficult to select a specific material and manufacturing technique. In this article, the results of using the APEKS method, which is a type of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method, are presented to select the best solution for the production of children’s furniture elements with surface structures similar to those of natural materials. Wood bark was selected as a material that, due to the sensory tactile sensations of dysfunctional children, could contribute to therapy and education. Comparative analysis was performed on the basis of the subtractive and additive methods used for manufacturing furniture products. Precise multiaxis milling of ash wood and 3D printing with fused filament fabrication technology using wood PLA filaments were carried out. The method used to select the best option considered quantitative and qualitative criteria in the assessment. Various parameters characterizing the surfaces were analyzed, such as geometric dimensions, hill heights, valley depths, and 3D surface parameters. The quality and surface roughness (Sa, Sz, Ssk, Sku, Sp, and Sv) parameters obtained based on 3D microscope measurements were determined. A scale of 1 to 10 was used to assess qualitative factors (i.e., usability and aesthetics). Based on the critical values obtained from the coefficient Kcri = 79.36, it was assumed that multiaxis wood milling was the best method for producing furniture elements with the required surface characteristics for use as therapeutic and educational tools for children with dysfunctions. The applied method allowed an effective evaluation of the compared variants of the production of furniture elements for customized applications.
Improved estimates for the linear Molodensky problem
Authors: Sansò Fernando , Betti Barbara 
Published: May 2024

AbstractThe paper deals with the linearized Molodensky problem, when data are supposed to be square integrable on the telluroidS, proving that a solution exists, is unique and is stable in a space of harmonic functions with square integrable gradient onS. A similar theorem has already been proved by Sansò and Venuti (J Geod 82:909–916, 2008). Yet the result basically requires thatSshould have an inclination of less than$$60^\circ $$60∘with respect to the vertical, or better to the radial direction. This constraint could result in a severe regularization for the telluroid specially in mountainous areas. The paper revises the result in an effort to improve the above estimates, essentially showing that the inclination ofScould go up to$$75^\circ $$75∘. At the same time, the proof is made precise mathematically and hopefully more readable in the geodetic community.

Published: May 2024

AbstractAggregatibacter actinomycetemcomitans is an opportunistic Gram-negative periodontopathogen strongly associated with periodontitis and infective endocarditis. Recent evidence suggests that periodontopathogens can influence the initiation and progression of oral squamous cell carcinoma (OSCC). Herein we aimed to investigate the effect of A. actinomycetemcomitans-derived extracellular vesicles (EVs) on OSCC cell behavior compared with EVs from periodontopathogens known to associate with carcinogenesis. EVs were isolated from: A. actinomycetemcomitans and its mutant strains lacking the cytolethal distending toxin (CDT) or lipopolysaccharide (LPS) O-antigen; Porphyromonas gingivalis; Fusobacterium nucleatum; and Parvimonas micra. The effect of EVs on primary and metastatic OSCC cells was assessed using cell proliferation, apoptosis, migration, invasion, and tubulogenesis assays. A. actinomycetemcomitans-derived EVs reduced the metastatic cancer cell proliferation, invasion, tubulogenesis, and increased apoptosis, mostly in CDT- and LPS O-antigen-dependent manner. EVs from F. nucleatum impaired the metastatic cancer cell proliferation and induced the apoptosis rates in all OSCC cell lines. EVs enhanced cancer cell migration regardless of bacterial species. In sum, this is the first study demonstrating the influence of A. actinomycetemcomitans-derived EVs on oral cancer in comparison with other periodontopathogens. Our findings revealed a potential antitumorigenic effect of these EVs on metastatic OSCC cells, which warrants further in vivo investigations.

Published: May 2024

AbstractGlycerol is a widely used signaling bioanalyte in biotechnology. Glycerol can serve as a substrate or product of many metabolic processes in cells. Therefore, quantification of glycerol in fermentation samples with inexpensive, reliable, and rapid sensing systems is of great importance. In this work, an amperometric assay based on one-step designed electroplated functional Pd layers with controlled design was proposed for a rapid and selective measurement of glycerol in yeast fermentation medium. A novel assay utilizing electroplated Pd-sensing layers allows the quantification of glycerol in yeast fermentation medium in the presence of interfering species with RSD below 3% and recoveries ranged from 99 to 103%. The assay requires minimal sample preparation, viz. adjusting of sample pH to 12. The time taken to complete the electrochemical analysis was 3 min. Remarkably, during investigations, it was revealed that sensitivity and selectivity of glycerol determination on Pd sensors were significantly affected by its adsorption and did not depend on the surface structure of sensing layers. This study is expected to contribute to both fundamental and practical research fields related to a preliminary choice of functional sensing layers for specific biotechnology and life science applications in the future.
