Social commerce (s-commerce) offers community-based platforms that facilitate customer-to-customer interactions and the development of customers' social shopping-based experience. While prior research has addressed the role of customer engagement (CE) in boosting s-commerce-based sales and performance, insight into the effect of s-commerce attributes on CE remains tenuous. Addressing this gap, this study examines the role of specific s-commerce attributes (i.e. community, collaboration, interactivity and social dynamics) on CE, which is, in turn, proposed to impact customers' repurchase- and electronic word of mouth (eWOM) intention.

A web-based survey was deployed to target users of a popular s-commerce platform, Etsy.com. Partial least squares structural equation modeling (PLS-SEM) was, then, used to analyze the survey data collected from 390 users.

The results reveal that the four examined attributes positively affect CE. The findings also demonstrate CE's positive effect on customers' repurchase- and eWOM intention.

Though CE has been identified as a key s-commerce performance indicator, little remains known about the role of specific s-commerce attributes in driving CE, as, therefore, explored in this research. Specifically, the authors examine the role of s-commerce-based community, collaboration, interactivity and social dynamics on CE. Their analyses also corroborate that CE, in turn, drives customers' post-purchase (i.e. repurchase/eWOM) intention. Managerially, our findings can be used to develop more engaging s-commerce platforms.

The purpose of this paper is to present an up-to-date survey on the non-orthogonal multiple access (NOMA) technique with co-operative strategy, a fast-evolving fifth-generation (5 G) technology. NOMA is used for serving many mobile users, both in power and code domains. This paper considers the power-domain NOMA, which is now discussed as NOMA.

The first part of the paper discusses NOMA-based cooperative relay systems using different relay strategies over different channel models. In various research works, the analytical expressions of many performance metrics were derived, measured and simulated for better performance of the NOMA systems. In the second part, a brief introduction to diversity techniques is discussed. The multiple input and multiple output system merged with cooperative NOMA technology, and its future challenges were also presented in this part. In the third part, the paper surveys some new conceptions such as cognitive radio, index modulation multiple access, space-shift keying and reconfigurable intelligent surface that can be combined with NOMA systems for better performance.

The paper presents a brief survey of diverse research projects being carried out in the field of NOMA. The paper also surveyed two different relaying strategies that were implemented in cooperative NOMA over different channels and compared several performance parameters that were evaluated and derived in these implementations.

The paper provides a scope for recognizable future work and presents a brief idea of the new techniques that can be united with NOMA for better performance in wireless systems.

This study aims to assess the usability of augmented reality (AR) based mobile app for excavation and earthmoving processes using a novel tool entitled Excavator Augmented Reality (EAR).

A mixed-methods research approach was used through conducting experimentation to collect qualitative and quantitative data collected from the Sri Lankan construction sector. EAR app was used for experimentation in outdoor areas examining how a 360° tracked hydraulic excavator can be navigated in different physical environments similar to the real prospected job.

The findings reveal that EAR could make a considerable impact on enhancing productivity, safety and training processes. However, the developed EAR App subjected to assessment demonstrated the highest satisfaction gap for the auditory aspects. Among the remaining criterion, the satisfaction met user expectations for comfortability and no-risk practice. An analysis of strengths, weaknesses, opportunities and threats (SWOT analysis) conducted revealed that visualising the excavator activities and the requirements of improved features were the highest agreed strengths and weaknesses of the EAR. Among the opportunities for improvement, the necessity of improving emergency and safety reached the highest agreement. Moreover, the study presented the challenges in introducing mobile augmented reality (MAR) to the construction sector under the political, economic, sociocultural, technological, environmental and legal (PESTEL) model along with solutions to be taken.

This study provides a novel approach to addressing the safety, productivity and training concerns in heavy mobile plants and machinery on construction sites which remains to be unexplored to this end.

This paper aims to provide a comprehensive systematic review using bibliometric analysis on the metaverse in health education and analyze the trends and patterns of research output within the field.

The paper conducts bibliometric analysis and follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to ensure a rigorous and transparent review process. Specifically, this article identifies research questions, develops a data-collection strategy and establishes a screening approach that includes determining relevant keywords and applying inclusion and exclusion criteria.

A bibliometric analysis is conducted comprising 231 studies from 145 scientific journals to assess the trends, patterns and collaboration networks in research on the use of metaverse technology in health education. This paper provides insights into the research themes, publication trends and countries leading in this field, which can guide future research in this field.

The use of metaverse technology in health education has gained momentum in recent years. Despite this interest, comprehensive studies to review and analyze the existing literature on this topic systematically are lacking. In response, this paper provides a systematic review that explores the potential role of the metaverse in health education. By considering the current research, key trends, research hotspots and opportunities for future investigations are identified. The findings not only shed light on the current state of research but also offer guidance for advancing this exciting field.

Construction is a risky industry. Therefore, organizations are seeking ways towards improving their safety performance. Among these, the integration of technology into health and safety leads to enhanced safety performance. Considering the benefits observed in using technology in safety, this study aims to explore digital technologies' use and potential benefits in construction health and safety.

An extensive bibliometrics analysis was conducted to reveal which technologies are at the forefront of others and how these technologies are used in safety operations. The study used two different databases, Web of Science (WoS) and Scopus, to scan the literature in a systemic way.

The systemic analysis of several studies showed that the digital technologies use in construction are still a niche theme and need more assessment. The study provided that sensors and wireless technology are of utmost importance in terms of construction safety. Moreover, the study revealed that artificial intelligence, machine learning, building information modeling (BIM), sensors and wireless technologies are trending technologies compared to unmanned aerial vehicles, serious games and the Internet of things. On the other hand, the study provided that the technologies are even more effective with integrated use like in the case of BIM and sensors or unmanned aerial vehicles. It was observed that the use of these technologies varies with respect to studies conducted in different countries. The study further revealed that the studies conducted on this topic are mostly published in some selected journals and international collaboration efforts in terms of researching the topic have been observed.

This study provides an extensive analysis of WoS and Scopus databases and an in-depth review of the use of digital technologies in construction safety. The review consists of the most recent studies showing the benefits of using such technologies and showing the usage on a systemic level from which both scientists and practitioners can benefit to devise new strategies in technology usage.

This paper aims to address the novel phenomenon of tourism in the metaverse and analyse possible scenarios that could influence the resilience of a sustainable tourism paradigm in response to this new phenomenon.

Based on Kuhn’s paradigmatic framework, this paper offers an innovative perspective for the integration of new theories and practise-relevant phenomena. It emphasises the relevance and commensurability of different paradigmatic dimensions and outlines the scenarios for the integration of metaversal sustainability.

The phenomenon of tourism in the metaverse of the 21st century poses a new challenge to the existing paradigm of sustainable tourism, which traditionally focuses on the economic and ecological sustainability of planet Earth’s physical environment. The adoption of a metaversal sustainability scenario for the virtual and mixed reality is key to a responsible implementation of the paradigm of sustainable tourism development that considers all its environments, whether fantastic or realistic.

This study has its limitations, as metaversal tourism is still in the experimental phase. A more comprehensive understanding of the metaverse and its terminology is still evolving. There is potential to adapt the sustainable tourism paradigm to new technological environments if the metaverse is recognized as one in the future.

There are practical implications for tourism policy and practise. Tourism stakeholders need to adapt to the changing tourism landscape by recognising the metaverse as a viable environment committed to sustainable development. This will enable innovative strategies to govern, lead, promote and manage metaversal tourism and ensure that it is in line with the long-term goal of sustainability.

The metaverse holds considerable potential for transforming social perception and behaviour. Integrating the metaverse into the sustainability pillars of the sustainable development paradigm implies a forward-looking approach that takes into account the dynamics of people’s evolving desires and preferences. This inclusion advocates for sustainable development in all environments in which people live and explore.

This research stands out for its pioneering role in advancing a sustainable tourism paradigm that goes beyond the traditional planetary dimensions. By examining the impact of tourism in the metaverse, it proposes a path towards a more holistic and future-oriented paradigm of sustainable tourism in both the physical and virtual worlds. The coining of the term “metaversal sustainability” contributes to the lexicon of paradigms for both tourism and societal sustainable development.

Basado en el marco paradigmático de Kuhn, este artículo ofrece una perspectiva innovadora sobre la integración de nuevas teorías y fenómenos relevantes para la práctica. Se destaca la relevancia y conmensurabilidad de las diferentes dimensiones paradigmáticas y esboza escenarios para la integración de la sostenibilidad del metaverso. Esta conceptualización se presenta visualmente en una ilustración que combina entornos de sostenibilidad virtuales y físicos. La visualización se complementa con una imagen que muestra a un turista en el metaverso, creada con el generador de imágenes DALL-E OpenAI.

Este trabajo de perspectiva aborda el novedoso fenómeno del turismo en el metaverso y analiza posibles escenarios que podrían influir en la resiliencia de un paradigma de turismo sostenible en respuesta a este nuevo fenómeno.

El fenómeno del turismo en el metaverso del siglo XXI plantea un nuevo reto al paradigma existente del turismo sostenible, que tradicionalmente se centra en la sostenibilidad económica y ecológica del entorno físico del planeta Tierra. La adopción de un escenario de sostenibilidad metaversal para la realidad virtual y mixta es clave para una aplicación responsable del paradigma de desarrollo turístico sostenible que tenga en cuenta todos sus entornos, ya sean ficticios o realistas.

Este estudio presenta limitaciones dado que el turismo metaversal se encuentra todavía en fase experimental. Una comprensión más completa del metaverso y su terminología está aún en evolución. Existe potencial para descubrir nuevas soluciones prácticas innovadoras e imprevistas para adaptar el paradigma del turismo sostenible a los nuevos entornos tecnológicos, si es que el entorno del metaverso se considera como tal en el futuro.

Existen implicaciones prácticas para la política y la práctica del turismo. Los agentes del turismo deben adaptarse al cambiante panorama turístico reconociendo el metaverso como un entorno viable y comprometido con el desarrollo sostenible. Esto permitirá aplicar estrategias innovadoras para gobernar, liderar, promover y gestionar el turismo del metaverso, así como garantizar que esté en consonancia con el objetivo a largo plazo de la sostenibilidad.

El metaverso encierra un potencial considerable para transformar la percepción y el comportamiento social. La integración del metaverso en los pilares de sostenibilidad del paradigma del desarrollo sostenible implica un enfoque prospectivo que tenga en cuenta la dinámica de los deseos y preferencias cambiantes de las personas. Esta inclusión aboga por el desarrollo sostenible en todos los entornos en los que viven y exploran las personas.

Esta investigación destaca por su papel pionero en el avance de un paradigma de turismo sostenible que va más allá de las dimensiones planetarias tradicionales. Al examinar el impacto del turismo en el metaverso, se propone un camino hacia un paradigma de turismo sostenible más holístico y orientado al futuro, tanto en el mundo físico como en el virtual. La acuñación del término “sostenibilidad metaversal” contribuye al léxico del paradigma tanto del turismo como del desarrollo sostenible de la sociedad.

The purpose of this paper is to investigate, from a thorough review of the literature, the role of metaverse-based quality 4.0 (MV-based Q4.0) in achieving manufacturing resilience (MFGRES). Based on a categorization of MV-based Q4.0 enabler technologies and MFGRES antecedents, the paper provides a conceptual framework depicting the relationship between both areas while exploring existing knowledge in current literature.

The paper is structured as a comprehensive systematic literature review (SLR) at the intersection of MV-based Q4.0 and MFGRES fields. From the Scopus database up to 2023, a final sample of 182 papers is selected based on the inclusion/exclusion criteria that shape the knowledge base of the research.

In light of the classification of reviewed papers, the findings show that artificial intelligence is especially well-suited to enhancing MFGRES. Transparency and flexibility are the resilience enablers that gain most from the implementation of MV-based Q4.0. Through analysis and synthesis of the literature, the study reveals the lack of an integrated approach combining both MV-based Q4.0 and MFGRES. This is particularly clear during disruptions.

This study has a significant impact on managers and businesses. It also advances knowledge of the importance of MV-based Q4.0 in achieving MFGRES and gaining its full rewards.

This paper makes significant recommendations for academics, particularly those who are interested in the metaverse concept within MFGRES. The study also helps managers by illuminating a key area to concentrate on for the improvement of MFGRES within their organizations. In light of this, future research directions are suggested.

Information management workflow in building information modelling (BIM)-based collaboration is based on using a common data environment (CDE). The basic premise of a CDE is exposing all relevant data as a single source of truth and facilitating continuous collaboration between stakeholders. A multitude of tools can be used as a CDE, however, it is not clear how the tools are used or if they fulfil the users’ needs. Therefore, this paper aims to investigate current practices of using CDEs for information management during the whole built asset’s life cycle, through a state-of-the-art literature review and an empirical study.

Literature data is collected according to the PRISMA 2020 guideline for reporting systematic reviews. This paper includes 46 documents in the review and conduct a bibliometric and thematic analysis to identify the main challenges of digital information management. To understand the current practice and the views of the stakeholders using CDEs in their work, this paper used an empirical approach including semi-structured interviews with 15 BIM experts.

The results indicate that one of the major challenges of CDE adoption is project complexity and using multiple CDEs simultaneously leading to data accountability, transparency and reliability issues. To tackle those challenges, the use of novel technologies in CDE development such as blockchain could be further investigated.

The research explores the major challenges in the practical implementation of CDEs for information management. To the best of the authors’ knowledge, this is the first study on this topic combining a systematic literature review and fieldwork.

This article explores the implications of virtual social spaces for conceptualizing community engagement in the practice of architecture and design by critically analyzing multidisciplinary approaches to conceptualizing community namely space, place, and context to envision social spaces of virtual community engagement by architects and designers.

This conceptual article utilized narrative literature review as the primary method for conducting a transdisciplinary theoretical integration. First, the authors defined the metaverse as all manner of human-technological interaction. Second, the authors discussed theories of place from architecture, social geography, and human ecology and employed neoecological theory to describe the interactional processes inherent in research and practice with virtual communities. Finally, the authors documented specific types of virtual engagement strategies in architectural research and practice.

Virtual environments provide varied opportunities for effective collaborations among architects, designers, and community members. The primary strategies identified by the literature review of virtual community engagement were collaborative, augmented reality, and situated digital experiences. In addition, researchers have found that the most effective community engagement bridges interactions in the physical space and digitally mediated interactions.

The authors advocate for increased research towards understanding how the expanded availability of more complex technological tools, such as future versions of artificial intelligence (AI) software, may further layer the landscape of community engagement in ways that may be unpredictable and currently less understood. Additional research is also needed to address participants' perspectives in virtual community engagement and explore how the building of communities in the meta-context is felt, lived, and understood by those who act in them.

The availability of new technological tools and digital platforms challenges diverse professionals to expand their community-engaged practice into the metaverse. Although not every community has broadband Internet or software access, many physical locations whether community centers, libraries, schools, or one’s own home may serve as safe spaces for novel virtual engagement experiences by individuals and groups. Digital engagement can increase opportunities for involvement from persons who are home-bound, lack transportation or child-care to attend in-person community events, or may desire the anonymity afforded by virtual engagement.

Virtual environments can provide varied opportunities for effective collaboration among architects, designers, and community members by overcoming physical or nonphysical barriers to in-person engagement. For example, recent case studies of civic and community organizations have successfully integrated physical and virtual community engagement during the global COVID-19 pandemic by overcoming physical or nonphysical barriers to in-person engagement. Community development theorists have referred to such contexts as a “post-place community” in which individuals find solidarity through digital global networks.

This article theorizes virtual community engagement in the metaverse from a transdisciplinary perspective and coins the innovative concept of meta-contexts to describe a global “post-place” community. Integrating theories of place from architecture, social geography, and human ecology guides an original review of effective strategies for meta-contextual digital community engagement by architects and designers.
