Abstract

Purpose

The Metaverse is rapidly reshaping the understanding of tourism, yet the public perception of this new domain remains largely uncharted empirically. This paper aims to build on the technology acceptance model (TAM) and diffusion of innovations theory (DIT) to fill this gap, offering crucial insights that could inform scholars and practitioners in both the tourism and technology sectors.

Design/methodology/approach

Using a big-data approach, the authors applied machine learning to scrape comments made by social media users on recent popular posts or videos related to tourism in the Metaverse from three prominent social media platforms. The cleaning process narrowed down 15,461 comments to 2,650, which were then analysed using thematic, emotion and sentiment analysis techniques.

Findings

The thematic analysis revealed that virtual tourism evokes a complex range of public beliefs. While many express awe and excitement toward its immersive capabilities, others remain sceptical about authenticity compared to physical travel. Additional themes show people draw comparisons to real-world tourism, discuss technology’s role and note educational value and novelty. However, some comments raise concerns about potential societal harms, exploitation and mental health impacts. Sentiment analysis found over half of the comments positive, though some were negative. Emotion analysis showed contentment, happiness and excitement as most frequent, though sadness, worry and loneliness also featured. Overall, perceptions of Metaverse tourism encompass enthusiasm yet substantial ambivalence.

Originality/value

To the best of the authors’ knowledge, this study is one of the first to comprehensively analyse public discussions on Metaverse tourism. It takes TAM and Rogers’s DIT a step further and provides fresh insights into how these theories can be employed in the emerging field of Metaverse tourism. The themes revealed new conceptual insights into multidimensional factors shaping public beliefs about Metaverse tourism and thus informing scholarly research on virtual interaction and technology acceptance regarding Metaverse tourism. In addition, the results can help tourism providers, platforms and marketers address salient public beliefs and sentiments/attitudes in developing marketing offerings, experiences and communications. Over time, this analysis methodology can be used to track the evolving public perceptions of Metaverse tourism.

Abstract

Purpose

This study aims to prepare some disperse dyes based on pyrazole derivatives and fully evaluate their use as azo-disperse dyes linked with pyrazolo[1,5-a] pyrimidine. This study aims to prepare dye polyester fabric at different conditions (pH and time) at a depth of 4% using a high-temperature pressure process in water.

Design/methodology/approach

The disperse dyes were created by dissolving enaminone and pyrazole derivatives in glacial acetic acid and fusing sodium acetate at reflux for 6 h. The chemical structure of the produced dye was studied using elemental analysis, Fourier-transform infrared spectroscopy, 1H NMR and 13C NMR spectroscopic analytical methods. The dyeing of Dispersed dyes 14–16 on polyester under diverse conditions was comprehensively investigated in this work.

Findings

The prepared Organic dyes 14–16 were found to be highly functional and suitable for this type of dyeing technique. High color strength is possessed by the materials dyed with Disperse dyes 14–16. Even in low alkaline conditions, these dyes exhibited a strong affinity for polyester fabric, changing just little in response to pH changes. The hue of the dyed polyester samples varied from beige to reddish brown and yellowish brown because of the coupler moieties.

Originality/value

This study is important because it offers novel dyes that may be used to dye polyethylene terephthalate fibers that exhibit remarkable brightness and levelness. It also offers a viable solution for creating a variety of colors in polyester fabrics.

Abstract

Purpose

This study focused on exploring the performance factors (PFs) that impact Infrastructure Sanitation Projects (ISSPs) in the construction sector. The aim was twofold: firstly, to identify these crucial PFs and secondly, to develop a robust performance model capable of effectively measuring and assessing the intricate interdependencies and correlations within ISSPs. By achieving these objectives, the study aimed to provide valuable insights into and tools for enhancing the efficiency and effectiveness of sanitation projects in the construction industry.

Design/methodology/approach

To achieve the study's aim, the methodology for identifying the PFs for ISSPs involved several steps: extensive literature review, interviews with Egyptian industry experts, a questionnaire survey targeting industry practitioners and an analysis using the Relative Importance Index (RII), Pareto principle and analytic network process (ANP). The RII ranked factor importance,  and Pareto identified the top 20% for ANP, which determined connections and interdependencies among these factors.

Findings

The literature review identified 36 PFs, and an additional 13 were uncovered during interviews. The highest-ranked PF is PF5, while PF19 is the lowest-ranked. Pareto principle selected 11 PFs, representing the top 20% of factors. The ANP model produced an application for measuring ISSP effectiveness, validated through two case studies. Application results were 92.25% and 91.48%, compared to actual results of 95.77% and 97.37%, indicating its effectiveness and accuracy, respectively.

Originality/value

This study addresses a significant knowledge gap by identifying the critical PFs that influence ISSPs within the construction industry. Subsequently, it constructs a novel performance model, resulting in the development of a practical computer application aimed at measuring and evaluating the performance of these projects.

Abstract

Purpose

This research investigates the moderating role of tariffs on the indirect relationship between the logistics performance index (LPI) and workers’ overall wages, specifically male and female wages through trade openness (TO). These wage metrics are proxies for assessing progress towards Sustainable Development Goal SDG-8.5.

Design/methodology/approach

Utilising a global dataset encompassing 168 economies from 2007 to 2018, the analysis employs a mediation effect analysis methodology to scrutinise the interconnectedness among LPI, TO, SDG and tariffs.

Findings

The findings reveal that LPI indirectly influences SDG-8.5 commitments of countries through their degree of TO. Moreover, the moderated mediation analysis elucidates that tariffs play a moderating role in the relationship between LPI and TO. However, the investigation finds no significant link between LPI and the wages of female workers, indicating a sub-component of SDG-8.5.

Research limitations/implications

This study significantly contributes to the existing literature on international development by elucidating the mechanisms and conditional factors through which logistics services can address the gender pay gap, as male workers’ wages predominantly drive the nexus, thereby advancing the fulfilment of the United Nations 2030 Agenda for Sustainable Development Goals.

Originality/value

This study utilises transaction cost theory and resource-based view theory and combines them with Okun’s Law and the Law of the wage curve to test the role of LPI as a source of competitive advantage in enhancing SDG-8.5 while taking into consideration TO and tariffs. This will help in extending both theories and enhance the understanding of their applicability worldwide.

Abstract

Purpose

This study aims to develop a way to inhibit fungal attacks on paper manuscripts, as fungi are a major deterioration factor that causes aesthetic appearance and fragility degradation using fungal inhibitors including silver nanoparticles (AgNPs) and titanium oxide nanoparticles (TiO2NPs).

Design/methodology/approach

In the present study, silver nanoparticles (AgNPs) and titanium oxide nanoparticles (TiO2NPs) doped with AgNPs (TiO2NPs@AgNPs) were produced and combined with cellulose acetate solution before membrane production. Thus, two distinct cellulose acetate (CA) membranes were created: AgNPs-loaded CA membranes (CAAg) and TiO2NPs@AgNPs-loaded CA membranes (CATAg). The fabricated membrane was applied to paper samples using cotton fibers containing ink or free of ink.

Findings

The findings revealed that these nanoparticles (AgNPs and TiO2NPs@AgNPs) have a distinct shape, small size and high stability. Furthermore, once loaded onto the CA membrane, such nanoparticles might suppress fungal assault on the surface of paper samples. According to the analysis and the acquired results, the CAAg membrane was the best material to use without affecting the paper’s properties.

Originality/value

This paper provides a novel approach for inhibiting the fungal attacks on paper manuscripts without affecting the paper properties by using membranes from cellulose acetate loaded onto nanoparticles as inhibitors.

Abstract

Purpose

This study aims to provide an efficient nanocomposite that might be used to protect deteriorated archaeological stucco.

Design/methodology/approach

The current experimental study evaluates the effectiveness of the hydroxyapatite nanoparticles (HA NPs) added to graphite carbon nitride (g-C3N4) and mixed with Paraloid (B-72) (B-44) in acetone in consolidating samples. The physicochemical properties of the as-prepared nanopowders have been investigated using Fourier transform infrared (FT-IR). This study involves monitoring the transmission electron microscope (TEM), X-ray diffraction (XRD) and Fourier transform changes in consolidated samples after exposure to various conditions by using the digital microscope and scanning electron microscopy to identify the appearance of the consolidated stucco samples after applying the selected nanocomposites and after their artificial aging procedures. Color change is measured using a colorimeter, and comparisons are made between samples before and after aging. Physical and mechanical properties are determined, and the contact angle is measured to measure hydrophobicity rate.

Findings

The obtained results indicate that HA/g-C3N4 hybrid nanocomposites with a composition of HA 0.5%/g-C3N4 1%/B-72 3% and HA 0.5%/g-C3N4 1%/B-44 3% achieved the best consolidating results among the proposed mixtures for stucco samples, where the percentage of weight loss was 0.77 with B-72, 0.53 with B-44. Surface identification and characterization of hydroxyapatite HA NPs/g-C3N4 hybrid nanocomposites embedded in B72/B44matrix were carried out using Scanning Electron Microscopy coupled with energy-dispersive x-ray spectroscopy (SEM–EDX).

Originality/value

This study provides important findings from the analytical procedures used to evaluate the consolidation materials used in this study. The findings are beneficial for the preservation of archaeological stucco. The investigation findings revealed that the most favorable outcomes were obtained from HA/g-C3N4 hybrid nanocomposites containing HA 0.5%, g-C3N4 1% and B-72 3%, as well as HA 0.5%, g-C3N4 1% and B-44 3%. Consequently, it is advised to use this nanocomposite to consolidate archaeological stucco, thus establishing a promising initial stride toward conserving archaeological stucco for future research endeavors. This study introduces a new nanocomposite material (HA NPs/G-C3N4) that can be used to protect and improve archaeological plaster. This is very important for preserving cultural heritage. The incorporation of nanotechnology improves the material’s physical and mechanical qualities. The research uses various characterization techniques (including TEM, XRD and FT-IR) to meticulously analyze the physicochemical properties of the nanocomposite material and assess its efficacy in practical applications through artificial aging experiments, offering novel insights and methodologies for future cultural relic preservation studies.

Abstract

Purpose

In recent years, the global focus has increasingly shifted toward the adoption of electric vehicles (EVs) due to growing concerns about environmental sustainability and the imperative of reducing greenhouse gas emissions. The transportation sector, a significant contributor to air pollution and climate change, faces increasing pressure to embrace EVs as a solution. However, the resistance exhibited by customers toward adopting new technology poses a substantial obstacle to the widespread adoption of EVs. Drawing on the link between theory of reasoned action (TRA) and self-congruity theory, this research aims to determine the factors that affect the customer intention toward EV.

Design/methodology/approach

The research conducts a questionnaire collecting 950 respondents from the Egyptian market. The research used primary quantitative data from online and self-administered questionnaires.

Findings

The findings indicated that green trust, price sensitivity and reliability have a positive impact on customer’s intention. However, self-image congruence was not affecting customer intention. For the moderating role of financial self-efficacy, it is affecting the relationship between price sensitivity and customer’s purchase intentions toward EV.

Research limitations/implications

This research will expand the theory by conceptualizing its abstract notions through research variables and implementing them in the Egyptian market. Furthermore, it links the two distinct theories. This knowledge can be utilized by policymakers and stakeholders to expedite the adoption of EVs in the Egyptian market.

Originality/value

This study presents a conceptual framework for managers and policymakers about the factors that affect the customer to buy EVs, since the international organizations emphasize eco-friendly transportation systems.

Abstract

Purpose

This study examines the impact of humble leadership on the service recovery performance (SRP) of frontline service employees (FSEs) in the hospitality industry. It also explores the mediating underlying mechanisms of psychological empowerment and employee engagement, along with the moderating role of employee proactive personality.

Design/methodology/approach

To test our predictions, we used a cross-sectional research design, drawing on a sample of 456 frontline service employees in Egypt’s hospitality industry. The data were analyzed by using SPSS 27 and AMOS 22.

Findings

The study reveals a positive association between humble leadership and SRP, with psychological empowerment and employee engagement bridging this relationship. Furthermore, an employee’s proactive personality strengthens both the direct influence of humble leadership on these mediating mechanisms –psychological empowerment and engagement – and the indirect impact of humble leadership on SRP through these two mechanisms.

Practical implications

To foster SRP among frontline service employees, firms should promote humble leadership practices among their managerial and supervisory staff. In addition, leaders should enhance psychological empowerment and engagement among their employees while also seeking to recruit employees with proactive personalities.

Originality/value

This study extends the effect of humble leadership to SRP, an unexplored consequence in current scholarly literature. Findings about the underlying mechanisms of psychological empowerment and engagement and the conditional effect of proactive personality deepen our understanding of how and when humble leaders are more effective in shaping SRP.
