Consumers in a Metaverse have an immersive engagement with products and services. This study aims to explore the multidimensional features of the Metaverse that influence consumers’ usage and gratifications, leading to their purchase behavior.

This study uses uses and gratifications theory to examine how hedonic, utilitarian and social gratifications influence Metaverse consumers’ retail behavior. Empirical analysis (N = 291) using structural equation modeling via SmartPLS and PLSpredict validated the model’s robustness and predictive accuracy.

Metaverse retail authenticity and virtuality influenced hedonic gratifications; autonomy and virtuality affected social gratification. Hedonic and social gratifications drove purchases, while utilitarian gratification had no significant effect.

This study applies uses and gratification theory to identify Metaverse-specific motivation factors, contributing to literature and aiding the practical design and development of Metaverse retail environments.

Internet of Things (IoT) interconnects many heterogeneous devices to each other, collecting and processing large volumes of data for decision making without human intervention. However, the information security concern it brings has attracted quite a lot of attention, and, at this stage, the smart step would be to analyze the security issues of IoT platform and get to the state of readiness before embarking upon this attractive technology. The purpose of this paper is to address these issues.

IoT risk assessment through the application of the analytical hierarchy process (AHP), a favorite multi-criteria decision making technique, is proposed. The IoT risks are prioritized and ranked at different layers, before which a well-defined IoT risk taxonomy is defined comprising of 25 risks across six layers of the IoT model for developing control and mitigation plans for information security of IoT.

People and processes layer, network layer and applications layer are the top three critical layers with risks like the lack of awareness, malware injection, malicious code injection, denial of service and inefficient policies for IoT practice get the highest priority and rank. Pareto analysis of the overall risk factors revealed that the top ten factors contribute to 80 percent of the risks perceived by information security experts.

The study focuses only on certain predefined constructs or layers of the IoT model traced from legacy studies. It is essential to re-look these constructs on a timely basis to prolong the results’ validity. The study’s empirical scope is confined only to the risk perception of select IoT experts and does not encompass a broader segment of the IoT ecosystem. Therefore, the risks assessment may not be sweeping to a bigger audience.

The study implications are two-fold: one it consolidates the earlier siloed works to intensify the need for risk assessment in the IoT domain, and second the study brings yet another contextual avenue of extending the application AHP and Pareto principle combination. The paper also draws specific critical organizational interventions about IoT risks. A comprehensive approach to prioritizing and ranking IoT risks are present in this research paper.

The contribution of this study to the benchmarking of IoT risk assessment is two-fold. One, a comprehensive risk assessment taxonomy is proposed, and two, the risks are prioritized and ranked to give a convincing reference for the organizations while making information security plans for IoT technology.

The purpose of this paper is to optimise the process parameters, namely, point angle, spindle speed and feed rate in the drilling of glass-reinforced stainless steel mesh polymer (GRSSMP) composites using grey relational fuzzy logic.

Based on the full factorial design, the experiments were conducted. The output responses considered are thrust force, torque, delamination and diameter deviation. Based on responses, the optimised process parameter was selected using grey-fuzzy reasoning analysis (GFRA).

The percentage contribution of the drilling parameters is analysed using analysis of variance (ANOVA), and the result shows that feed rate is the most influential factor in the drilling of GRSSMP composites.

The optimised drilling parameters have been used for drilling of polymer composites in the production industry.

Optimisation of process parameters during the drilling of GRSSMP composites using GFRA has not been performed previously.

Purpose of This Chapter: >The study examines the importance and effect of working over office hours and lengthy commutes on work–life balance because both consume time away from the official working hours. The study utilized perceived organizational support to measure the moderating role of working over office hours, lengthy commutes, and work–family balance.

Design / Methodology / Approach: An inferential statistics cross-sectional study collected data from 437 full-time employees of IT-BPM companies in 5 metropolitan cities in India. The study used the PLS-SEM to examine the hypotheses.

Findings: The results show a negative relationship between working over office hours and lengthy commutes on work–family balance. This study also found the moderating effect of perceived organizational support on working over office hours and lengthy commutes on the work–family balance. Also, the study revealed that half of the respondents spend three hours, and one-fourth of the respondents spend four and half hours working over office hours and lengthy commutes.

Research Limitations: This research is limited to IT-BPM companies in India. Nevertheless, the findings highlight the factors associated with IT-BPM employee work–family balance, and only two factors were identified.

Practical Implications: This study enhances the work–family balance’s theoretical and practical effects. The results provide a competitive benchmark for IT-BPM managers, administrators, and governing bodies of employee well-being.

Originality: To the best of the author’s knowledge, this study is the first to adopt extrinsic variables in work–family border theory to measure the work–family balance of IT-BPM employees.

Detecting O₂ gas in a confined space at room temperature is particularly important to monitor the work process of precision equipment. This study aims to propose a miniaturized, low-cost, mass-scale produced O₂ sensor operating around 30°C.

The O₂ sensor based on lanthanum fluoride (LaF₃) solid electrolyte thin film was developed using MEMS technology. The principle of the sensor was a galvanic cell H₂O, O₂, Pt | LaF₃ | Sn, SnF₂ |, in which the Sn film was prepared by magnetron sputtering, and the LaF₃ film was prepared by thermal resistance evaporation.

Through pretreatments, the sensor’s response signal to 40% oxygen concentration was enhanced from 1.9 mV to 46.0 mV at 30°C and 97.0% RH. Tests at temperatures from 30°C to 50°C and humidity from 32.4% RH to 97.0% RH indicated that the output electromotive force (EMF) has a linear relationship with the logarithm of the oxygen concentration. The sensitivity of the sensor increases with an increase in both humidity and temperature in the couple mode, and the EMF of the sensor follows well with the Nernst equation at different temperatures and humidity.

This research could be applied to monitor the oxygen concentration below 25% in confined spaces at room temperature safely without a power supply.

The relationship between temperature and humidity coupling and the response of the sensor was obtained. The nano-film material was integrated with the MEMS process. It is expected to be practically applied in the future.

People's fascination with historical sites led to the development of the dark tourism phenomenon. Today's tourism idea has been affected by the obsession with sorrow and death, and many tourists from across the world visit regions connected to Sri Lanka. A notable case study for the growth of dark tourism in Asia is Sri Lanka, a South Asian nation that has been involved in a 26-year civil war with the Tamil Tigers and has left behind an ingenious historical relic system. There tend to be many competing viewpoints when it comes to historical battle sites, but having a particular cause to go there gives individuals a variety of feelings and experiences. This research paper reviews academic research into dark tourism over the 1996–2016 period. The way that tourists view war memorials depends on how they understand “their reality” as it is presented by the location and its inhabitants. The structure and numerous facets of the dark areas in South Asian culture, which are distinguished by a certain sort of enlightened pilgrims and ancestral ceremonial practice, are identified using a qualitative research technique. This study aimed to address those research aims by conducting semi-structured interviews with members of the general population. The researcher examines the information obtained through the interpretation and tales of the tour leader. The study advances our knowledge of dark tourism generally and in the context of Sri Lankan war zones, where the role of dark tourism in Sri Lanka's history of war has been underappreciated.

Contextual to the recognition of the complex interplay between health and behavioral aspects, integrated behavioral health (IBH) has emerged. Although this model is becoming popular in the Western world, its presence in the global context is not promising. This paper aims to explore the need for IBH in India and address its barriers to implementation and possible solutions.

We analyzed the case of IBH and its potential implications for India using the current evidence base, authors' reflections and experience of implementing similar programs.

This paper identifies contextual factors, including increased instances of non-communicable diseases and psychosocial and cultural determinants of health, that necessitate the implementation of IBH programs in India. The key features of different IBH models and their applicability are outlined. The current status of IBH and potential challenges in implementation in India in terms of human resources and other factors are delineated. We also discuss the potential models for implementing IBH in India.

Integrating behavioral health in primary care is considered an effective and sustainable model to promote health and well-being across various target populations. Towards this end, this paper is the first to discuss the contextual factors of IBH in India. It is a significant addition to the knowledge base on IBH and its possible implementation barriers and strategies in low- and middle-income countries.

The construction industry has struggled with efficiency issues for decades. Organizational culture is identified as one of the biggest hindrances for the enhancement of efficiency in a highly labor-intensive sector such as construction. Based on recent academic studies, Finnish construction industry professionals would embrace clan and adhocracy culture features to achieve a better level of construction efficiency. The purpose of this paper is to investigate the promoters and the barriers for making the desired culture change happen in the case company.

The paper presents a semi-structured theme interview case study, including 12 in-depth interviews. The interviews were recorded, and later, transcribed into text, which forms the empirical data of this paper.

The Finnish construction industry must adopt a holistic approach to enhance its prevailing level of efficiency through the culture change. Basic learning and knowledge management processes seem to be missing from the industry and organizational levels. Better knowledge management in the case company would be the first step to start fixing this problem.

Because of the nature of a case study, the research results can be generalized only with caution in the Finnish construction industry. Generalizing the findings in another country would require further studies in a different cultural environment, e.g. in another European country.

The paper includes implications for the development of the organizational culture on the Finnish construction industry level and on an organizational level.

The found influencers are discussed through Engeström’s activity model for the first time in the construction culture context.

The purpose of this paper is to discuss published research in rotorcraft which has taken place in India during the last ten years. The helicopter research is divided into the following parts: health monitoring, smart rotor, design optimization, control, helicopter rotor dynamics, active control of structural response (ACSR) and helicopter design and development. Aspects of health monitoring and smart rotor are discussed in detail. Further work needed and areas for international collaboration are pointed out.

The archival journal papers on helicopter engineering published from India are obtained from databases and are studied and discussed. The contribution of the basic research to the state‐of‐the‐art in helicopter engineering science is brought out.

It is found that strong research capabilities have developed in rotor system health and usage monitoring, rotor blade design optimization, ACSR, composite rotor blades and smart rotor development. Furthermore, rotorcraft modeling and analysis aspects are highly developed with considerable manpower available and being generated in these areas.

Two helicopter projects leading to the “advanced light helicopter” and “light combat helicopter” have been completed by Hindustan Aeronautics Ltd These helicopter programs have benefited from the basic research and also provide platforms for further basic research and deeper industry academic collaborations. The development of well‐trained helicopter engineers is also attractive for international helicopter design and manufacturing companies. The basic research done needs to be further developed for practical and commercial applications.

This is the first comprehensive research on rotorcraft research in India, an important emerging market, manufacturing and sourcing destination for the industry.

Ranking and grading of architectural heritage (AH) are common for the conservation process. Decision-makers are often intuitively made decisions for the selection of the AH. However, on many occasions, these decisions are not transparent and sometimes focused only on a few aspects of the AH.

A transparent and robust methodology must be adopted to select and manage AH for the present and future generations. Selecting the list of parameters that are affecting the AH, and assessing their significance can strengthen the holistic assessment. From the literature, parameters and dimensions are identified for the evaluation of AH and its application for Odishan temple architecture (OTA). For minimizing biasedness associated with assessment, the research considered the opinion of experts, researchers and various stakeholders. For objective decision-making, the Delphi, the analytical hierarchy process (AHP) and the technique for order preference by similarity to ideal solutions (TOPSIS) methods were adopted.

Later, by observing the dimension-wise ranks and comparing the obtained grading of OTA with the existing state of protection, it was found that some temples, though having higher values with distinct dimension, lack significantly in other dimensions. However, for unbiased evaluation, all the possible dimensions should be considered. This methodology will also be useful for other decision-making processes concerning the same.

This research is limited to the OTA. However, this methodology can be adopted by changing the definitions of the parameters according to the contextual needs.

This methodology may be helpful for the further policy-making process for the conservation and management of such AH.

To date, OTA is not graded through such a methodology. Also, limited studies are found in similar line worldwide.
