The present work focuses on evaluating the physical and mechanical characteristics of geopolymer concrete (GPC) by replacing the sodium silicate waste (SSW) in place of traditional river sand. The aim is to create eco-friendly concrete that mitigates the depletion of conventional river sand and conserves natural resources. Additionally, the study seeks to explore how the moisture content of filler materials affects the performance of GPC.

SSW obtained from the sodium silicate industry was used as filler material in the production of GPC, which was cured at ambient temperature. Instead of the typical conventional river sand, SSW was substituted at 25 and 50% of its weight. Three distinct moisture conditions were applied to both river sand and SSW. These conditions were classified as oven dry (OD), air dry (AD) and saturated surface dry (SSD).

As the proportion of SSW increased, there was a decrease in the slump of the GPC. The setting time was significantly affected by the higher percentage of SSW. The presence of angular-shaped SSW particles notably improved the compressive strength of GPC when replacing a portion of the river sand with SSW. When exposed to elevated temperatures, the performance of the GPC with SSW exhibited similar behavior to that of the mix containing conventional river sand, but it demonstrated a lower residual strength following exposure to elevated temperatures.

Exploring the possible utilization of SSW as a substitute for river sand in GPC, and its effects on the performance of the proposed mix. Analyzing, how varying moisture conditions affect the performance of GPC containing SSW. Evaluating the response of the GPC with SSW exposed to elevated temperatures in contrast to conventional river sand.

The study seeks to explore why despite growing concern for the environment, consumers’ intention to purchase organic foods remains relatively low. In addition, the study also seeks to investigate the role of perceived marketplace influence (PMI) and moral norms in organic food consumption.

Data collected from 330 young consumers chosen with non-probability sampling were analysed using structural equation modelling in Amos 22.0.

The results of the parallel mediation analysis confirmed that environmental concern influences purchase intention indirectly through attitude, subjective norms, perceived behavioural control and perceived marketplace influence. In addition, moral norms were found to moderate the effect of perceived behavioural control on purchase intention. Moreover, the results also indicated that the impact of environmental concern on consumers’ attitude toward organic foods was also moderated by moral norms. Further, the results of moderated mediation showed that the indirect effect of environmental concern on purchase intention (through attitude and perceived behavioural control) was moderated by moral norms.

The study contributes to the existing literature by investigating the inconsistency between environmental concern and purchase intention. In addition, the study also investigate role of perceived marketplace influence and moral norms in stimulating organic food consumption intentions.

The emergence of perceived marketplace influence as an important determinant of organic food consumption shows that every individual needs to realise the importance of their environment friendly actions to promote organic food consumption. In addition, the study also highlights the pivotal role of moral norms in the promotion of organic food consumption. Thus, markets, policy-makers, family, friends, society all should promote and inculcate the spirit of contributing in the cause of safeguarding the environment to the young children specially by promoting consumption of organic foods.

The study examines the role of perceived marketplace influence as predictor of purchase intention towards organic foods which is rarely explored specially in the domain of organic food consumption. In addition, the results also produced some novel insights into the moderating role of moral norms.

The study aims to address a critical gap in existing healthcare payment schemes and care service pricing by recognizing the influential role of patients' decisions on self-management efforts. These decisions not only impact health outcomes but also shape the demand for care, subsequently influencing care costs. Despite the significance of this interplay, current payment schemes often overlook these dynamics. The research focuses on investigating the implications of a novel behavior-based payment scheme, designed to align incentives and establish a direct connection between patients' decisions and care costs. The primary objective is to comprehensively understand whether and how this innovative payment scheme structure influences key stakeholders, including patients, care providers, insurers and overall social welfare.

In this paper, we propose a game-theoretical model to incorporate the performance of self-management with the demand for healthcare service, compare the patient's effort decision for self-management and provider's price decision for healthcare service under a behavior-based scheme with that under two implemented widely payment schemes, that is, co-payment scheme and co-insurance scheme.

Our findings confirm that the behavior-based scheme incentives patient self-management more than current schemes while reducing their possibility of seeking healthcare service, which indirectly induces the provider to lower the price of the service. The stakeholders' utility under various payment schemes is sensitive to the cost of treatment and the perceived health utility of patients. Especially, patient health awareness is not always benefited provider profit, as it motivates patient self-management while diminishing the demand for care.

We provide a novel framework for characterizing behavior-based payment schemes. Our results confirm the need for modification of the current payment scheme to incentivize patient self-management.

This study aims to investigate the tendency that Malaysian consumers will choose the recombinant collagen-like protein (RCLP) from bacteria as an alternative source of collagen in their consumption and the determinants of the consumer acceptance.

Quantitative approach is adopted in the study. Descriptive analysis and logistic regression are used to analyze primary data collected from a survey.

The likelihood of consumers choosing RCLP as an alternative source of collagen is higher among elderly and females. The choice is significantly influenced by the idea that the collagen should support maqasid al-syariah, approved by national Islamic body, should clear on the ingredients used and could boost local economic activities in the future.

An ethical halal policy should be outlined as the guiding principles to the potential producers of RCLP.

An alternative source of collagen using bacteria as proposed is not yet being introduced in Malaysian industry, and the analysis on probability that consumers will accept this new sourced collagen product is using primary data from survey.

The purpose of this study is to explore the potential contribution of the metaverse to improve training and development as a function of human resource development (HRD) perspective. The authors explore the benefits and challenges of the metaverse and introduce cases of companies using the metaverse in training.

A narrative literature review was conducted to collect information on the metaverse in training. The authors reviewed peer- and non-peer-reviewed articles, book chapters, white papers, corporate websites and blogs and business magazines.

A total of 75 articles were reviewed, including 14 cases, which were summarized to demonstrate how companies are applying metaverse technology in training contexts. For a more in-depth review, three cases were selected and summarized in terms of context, process and outcomes.

The metaverse is an emergent topic in HRD. It has the potential to revolutionize the functions of training and development through the combination of advanced technologies, including virtual reality, augmented reality and mixed reality. This article is the foundational attempt to provide a comprehensive summary of existing literature and case studies that highlight the potential of the metaverse in training within the context of HRD.

The purpose of this paper is to analyse the metaverse platform in a social context to better understand the future of this tool in tourism cities and how this can help to improve the well-being of residents in both digital and physical scenarios.

In this paper, the current and probable developments in the metaverse, and its use in tourism cities and companies have been investigated. Moreover, this study develops, collects and examines the main metaverse definitions by expert authors and organizations as a methodology to ensure the transparency and credibility of the metaverse analysis.

Findings suggest that the fusion of the metaverse and tourism cities must create residents’ services and experiences in the new MetaTourPolis to help interact and connect citizens with the city’s institutions and companies, as well as make tourism cities more attractive, innovative, environmentally friendly and healthier places to live. Metaverse will bring new changes for residents and tourists, in fact, this virtual platform is already changing and improving the residents’ quality of life and people with disabilities in tourism cities. For instance, the metaverse platform has been implemented in Seoul, Santa Monica and Dubai MetaTourPolis to interact with their residents, including people with disabilities, to resolve bureaucratic and administrative problems, avoiding this group and the rest of the residents travelling by bus or car to the city’s institutions. In addition, several metaverse applications based on softbot tutors or metaverse virtual social centres have been developed to improve blind and impaired people, and elderly people’ quality of life, respectively.

A new concept called “MetaTourPolis” has been included to stage the relationship between tourism cities and the metaverse platform, where the fusion of metaverse and the new tourism polis of the 21st century will be at the service of citizens, tourists and companies, to create more sustainable, efficient, quantitative and environmental tourism cities.

Despite the increasing interest in the metaverse—immersive three-dimensional virtual worlds wherein personalized avatars interact with one another—little is known about how users cognitively appraise and emotionally experience it. To fill this gap, the present study explores the emotional, behavioral and social consequences of users' cognitive appraisals, while focusing on social virtual reality (VR) as a representative entry point to the metaverse.

Drawing on cognitive appraisal theory against the backdrop of a framework for classifying emotions, this study develops and tests a theoretical model to account for users' continuance intention and its consequences in the social VR context based on two-wave panel survey data collected from 216 users of social VR platforms, including AltspaceVR, VRChat, Bigscreen and Rec Room.

The results of the first survey showed that perceived opportunity was more strongly influenced by technological opportunity than social opportunity, whereas perceived threat was more strongly affected by social threat than technological threat. Integrating the data collected from the first survey with those of the second survey, we also found that users' continuance intention positively influenced both their behavioral engagement and social self-efficacy.

By adopting a longitudinal approach, this study provides insights that may be valuable to researchers and practitioners who seek to use social VR for business purposes. This study also contributes to the metaverse literature by conceptualizing and operationalizing the opportunity and threat factors of social VR and identifying salient emotions that users experience in this context. Finally, this study has practical implications for addressing the social and technological features that may cause adverse user experiences in social VR.

Despite the importance of emotional variables in shaping individuals' consumption behavior, nature-love still needs to be addressed concerning various aspects of sustainable consumption behavior (SCB). Considering the dimensions of nature-love, this study aims to investigate the effect of passion-for-nature, intimacy-with-nature and commitment-to-nature on SCB. Furthermore, this study aims to incorporate the construal levels of psychological distance (PD) as a moderating variable between the tested variables to add a more in-depth understanding.

Data was collected from a sample of 311 individuals from Egypt using the snowball sampling method and the ten-time rule technique. The data was analyzed using partial least squares-structural equation modeling (PLS-SEM).

The findings indicate that passion-for-nature and intimacy-with-nature have a significant positive effect on green purchasing, reusability and recycling. On the other hand, commitment-to-nature has a significant positive effect on both green purchasing and reusability. Additionally, a high PD acts as a moderator between the relationships tested. The findings have been discussed in terms of their theoretical and practical implications.

To the best of the authors’ knowledge, this is the first study to integrate PD as a moderator between the relationships tested. Additionally, this paper is the first empirical research investigating these relationships in developing economies.

The purpose of this study is to examine the key research question, which is whether fintech innovation for financial inclusion has been successful in India? As fintech has been popular in many countries, there is very little understanding on how successful it has performed in India for financial inclusion. This research attempts to ravel important factors that may or may not have a direct or indirect impact on fintech innovation for financial inclusion, thereby dissecting the empirical data to reveal important information for the reader.

This study covers a comprehensive literature review, from which key variables are discovered, then develops hypotheses to be examined, followed by proposing a research model. The survey data examines important research instruments for fintech inclusion in India, identifying and measuring factors, leading to partial least squares (PLS) model testing. Finally, the key findings are reported.

The findings reveal that fintech innovation from variables such as users experience and motivation for digital payments drives usefulness and ease of use leading to financial inclusion. The security, trust, transparency and customer support when built into the fintech innovation for digital payments influences perceived ease of use (PEOU) and usefulness that mediates to uplift financial inclusion directly. Whereas perceived usefulness (PU) anchoring happens to be a precursor for the financial inclusion. On the contrary, cultural values for fintech innovation through PEOU and usefulness had no impact whatsoever on financial inclusion, thus demystifying cultural influences as non-influential factor.

Research limitations are that the study was conducted in India, and may not be generalised in other countries; however, it can be modified to fit future research. Survey data captured was from a particular region of South India, which may differ from the rest of the country. The sample size and research period were adequate; however, larger data sets would be more meaningful for longitudinal studies. As India is the second most populous country in the world, a comparison with other similar countries of the same size and geographical location will be useful for future research.

This research reveals that financial inclusion is much more complex than previously known and that the penetration of fintech has the capacity to go deeper and include a large number of people into the mainstream financial system and ameliorate the inequities in urban-rural gender and caste. The user’s experience, culture and motivations positively influenced the usefulness and ease of use for driving the financial inclusion of digital payments. Further security, trust, transparency and customer support can facilitate the use of central bank digital currency (CBDC) as a tool for financial inclusion.

Fintech innovation for financial inclusion is based on the successful acceptance of the digital payment system by people in the society. This research has identified that for any fintech innovation, it is essential that society needs to benefit from it. Encouraging a larger population to switch to digital payments offer challenges and opportunities. While the opportunities are enormous research suggests that early adopters of new technology go through different phases of testing, in which a society can completely accept an innovation or can completely reject an innovation if the two mediating factors such as PU and ease of use do not perform as predicted, thus having a higher failure rate. On the other side, if such an innovation as fintech becomes successful it has the capacity to bring billions of people into mainstream financial inclusion, a success story that can greatly benefit the Indian society and which can be replicated among other countries in the world.

To the best of the authors’ knowledge, this study is the first attempt in an effort to understand the influential factors from the point of view of users for the adoption of CBDC for financial inclusion. The main contribution of this paper is to examine the role of CBDC as an instrument to foster financial inclusion in India, which has not been attempted so far. The originality also lies to the heart of the research is dissecting and making meaningful sense of the empirical data, developing and measuring research instruments and hypotheses and finally adopting a PLS model to answer the key research question, which is whether fintech innovation for financial inclusion can be successful for India?

The objective of this study is to determine the efficiency of tourist accommodation companies located in the main tourist area of southern Europe as one of the three elements of the local sustainable development triangle.

The analysis, carried out using the data envelopment analysis (DEA) methodology on 130 companies, has obtained that from the CCR perspective (results-oriented method when companies present constant returns on the input variables).

The companies involved are quite inefficient, while which from the BCC perspective (where the input and output variables used in the company respond to a variable and not constant scale) are quite efficient. The efficiency of these companies in the seven provinces of Andalusia has also been analysed to determine if there are patterns that differentiate them and thus be able to propose strategies that improve the sustainability of these territories. The conclusions of the study indicate the need to improve the operational efficiency of rural accommodation companies.

The analysis of efficiency in the hotel sector and even more so in the rural tourism sector is relatively scarce in the literature, especially in Spain. More specifically, Rubio and Román (2006) have demonstrated the existence of scale inefficiencies in hotels, but no evidence has been found in previous studies that this behaviour carries over to accommodation establishments located in the destinations under study.
