Abstract
Purpose
The utilisation of renewable energy sources for generating electricity and potable water is one of the most sustainable approaches in the current scenario. Therefore, the current research aims to design and develop a novel co-generation system to address the electricity and potable water needs of rural areas.
Design/methodology/approach
The cogeneration system mainly consists of a solar parabolic dish concentrator (SPDC) system with a concentrated photo-voltaic module at the receiver for electricity generation. It is further integrated with a low-temperature thermal desalination (LTTD) system for generating potable water. Also, a novel corn cob filtration system is introduced for the pre-treatment to reduce the salt content in seawater before circulating it into the receiver of the SPDC system. The designed novel co-generation system has been numerically and experimentally tested to analyse the performance at Karaikal, U.T. of Puducherry, India.
Findings
Because of the pre-treatment with a corn cob, the scale formation in the pipes of the SPDC system is significantly reduced, which enhances the efficiency of the system. It is observed that the conductivity, pH and TDS of seawater are reduced significantly after the pre-treatment by the corncob filtration system. Also, the integrated system is capable of generating 6–8 litres of potable water per day.
Originality/value
The integration of the corncob filtration system reduced the scaling formation compared to the general circulation of water in the hoses. Also, the integrated SPDC and LTTD systems are comparatively economical to generate higher yields of clean water than solar stills.

Abstract
Purpose
This paper aims to investigate multidimensional customer engagement behaviors (CEBs) as antecedents of action loyalty in hospitality contexts and examine service conditions that inhibit and facilitate the former relationship.
Design/methodology/approach
This paper tests a holistic framework based on transaction data from 5,855 active members of a hotel firm. The hypotheses are examined using ordinary least squares regression.
Findings
By integrating transaction-related CEBs with non-transaction-related CEBs, this paper found that three CEB constructs (i.e. feedback, mobilizing and cross-buying) contribute significantly to action loyalty in hospitality contexts. These effects vary depending on the inhibitor (service failure) and the facilitator (service customization).
Practical implications
Hotel managers should value customer engagement as a marketing tool to retain customers. When engaged customers encounter service failure and customization, managers can react differently to facilitate consumers’ action loyalty.
Originality/value
Contrary to prior studies focusing on the effects of general CEBs on attitudinal loyalty, this study examines the diverse impacts of multidimensional CEBs on customers’ action loyalty and confirms boundary conditions to coordinate the effects between CEBs from a hotel firm’s perspective.

Abstract
Purpose
The paper aims to focus on underpinning the moderating role of work meaningfulness in alleviating the impact of general job demands on burnout directly and via work–family conflict by drawing on the conservation of resources theory.
Design/methodology/approach
Survey methodology was used for this study, using standardized instruments to assess general job demands, meaningfulness, work–family conflict and burnout. The survey was administered to school teachers (n = 800), and the data set was analyzed through SmartPLS 4.0.
Findings
This study ascertained that work meaningfulness moderated the relationship between general job demands and burnout. This study also found that general job demands under conditions of low work meaningfulness positively affected burnout through work–family conflict, thereby validating the moderated mediation model.
Originality/value
While several studies have established the relationship between general job demands, work–family conflict and burnout, to the best of the authors’ knowledge, this is the first study that examined the moderating role of work meaningfulness in the relationship, where work meaningfulness has emerged as a suitable moderator in lowering the impact of job demands on burnout via a work–family conflict. This study contributes to the extant literature on work meaningfulness and adds utility to practice.

Abstract
Purpose
In the past decade, three-dimensional (3D) printing has gained attention in areas such as medicine, engineering, manufacturing art and most recently in education. In biomedical, the development of a wide range of biomaterials has catalysed the considerable role of 3D printing (3DP), where it functions as synthetic frameworks in the form of scaffolds, constructs or matrices. The purpose of this paper is to present the state-of-the-art literature coverage of 3DP applications in tissue engineering (such as customized scaffoldings and organs, and regenerative medicine).
Design/methodology/approach
This review focusses on various 3DP techniques and biomaterials for tissue engineering (TE) applications. The literature reviewed in the manuscript has been collected from various journal search engines including Google Scholar, Research Gate, Academia, PubMed, Scopus, EMBASE, Cochrane Library and Web of Science. The keywords that have been selected for the searches were 3 D printing, tissue engineering, scaffoldings, organs, regenerative medicine, biomaterials, standards, applications and future directions. Further, the sub-classifications of the keyword, wherever possible, have been used as sectioned/sub-sectioned in the manuscript.
Findings
3DP techniques have many applications in biomedical and TE (B-TE), as covered in the literature. Customized structures for B-TE applications are easy and cost-effective to manufacture through 3DP, whereas on many occasions, conventional technologies generally become incompatible. For this, this new class of manufacturing must be explored to further capabilities for many potential applications.
Originality/value
This review paper presents a comprehensive study of the various types of 3DP technologies in the light of their possible B-TE application as well as provides a future roadmap.

This paper aims to design an optimum vertical axis wind turbine (VAWT) and assess its techno-economic performance for wind energy harvesting at high-speed railway in Malaysia.
Abstract
Purpose
This paper aims to design an optimum vertical axis wind turbine (VAWT) and assess its techno-economic performance for wind energy harvesting at high-speed railway in Malaysia.
Design/methodology/approach
This project adopted AutoCAD and ANSYS modeling tools to design and optimize the blade of the turbine. The site selected has a railway of 30 km with six stops. The vertical turbines are placed 1 m apart from each other considering the optimum tip speed ratio. The power produced and net present value had been analyzed to evaluate its techno-economic viability.
Findings
Computational fluid dynamics (CFD) analysis of National Advisory Committee for Aeronautics (NACA) 0020 blade has been carried out. For a turbine with wind speed of 50 m/s and swept area of 8 m2, the power generated is 245 kW. For eight trains that operate for 19 h/day with an interval of 30 min in nonpeak hours and 15 min in peak hours, total energy generated is 66 MWh/day. The average cost saved by the train stations is RM 16.7 mil/year with battery charging capacity of 12 h/day.
Originality/value
Wind energy harvesting is not commonly used in Malaysia due to its low wind speed ranging from 1.5 to 4.5 m/s. Conventional wind turbine requires a minimum cut-in wind speed of 11 m/s to overcome the inertia and starts generating power. Hence, this paper proposes an optimum design of VAWT to harvest an unconventional untapped wind sources from railway. The research finding complements the alternate energy harvesting technologies which can serve as reference for countries which experienced similar geographic constraints.

This study aims to examine the correlates of burnout among primary school teachers working with public schools in Chhattisgarh-India.
Abstract
Purpose
This study aims to examine the correlates of burnout among primary school teachers working with public schools in Chhattisgarh-India.
Design/methodology/approach
Data were collected from 713 teachers using a questionnaire survey. Using partial least square path modeling, this study tests the proposed measurement and structural model.
Findings
The study confirmed that general job demands and emotional job demands in a school environment significantly correlated with burnout, which, in turn, has increased somatic symptoms and decreased pro-social behavior among teachers. However, the association of burnout with absenteeism was insignificant. Emotional intelligence (EI) was found to buffer the adverse associations of general job demands and emotional job demands on burnout.
Practical implications
The findings of this study demonstrate that EI has buffering effects on high job demands that consequently reduce burnout. This will help educators and policymakers in shaping and formulating effective policies and practices to deal with burnout.
Originality/value
Earlier studies exploring burnout of primary school teachers, especially in the Indian context, had focused exclusively on demographic factors. This study is an early attempt to understand the impact of contextual factors on burnout thereby helping in designing appropriate interventions thereof. This study additionally rationalizes the unexplored association of burnout with pro-social behavior among educators.

Abstract
Purpose
Though the concept of work engagement has been extensively explored in the academic literature, however, with engagement levels declining globally – causing hike in undesired employee attitudes and behaviours – there is a need to revisit its antecedents and consequences that bear higher current relevance. Within the context of the Indian information technology (IT) sector, this study aims to explore the role of job security and value congruence as two critical antecedents which not only lead to increased engagement levels but also consequently yield the enhanced perception of change, amplified general life satisfaction and reduced intent to leave among employees.
Design/methodology/approach
Data were collected from 363 software developers (SDs) in India using the survey questionnaire method and structured equation modelling was used to test the proposed measurement and structural model. The results supported the proposed hypotheses and confirmed the role of work engagement as a mediator between the studied antecedents and consequences.
Findings
Results from a study of 363 SDs across India support the proposed hypotheses and confirm the role of work engagement as a mediator between the studied antecedents and consequences.
Research limitations/implications
This study was cross-sectional; therefore, caution is necessary while making any causal inferences. Further work based on longitudinal data would strengthen these findings.
Practical implications
The findings of the study will provide the decision-makers of IT companies with tools to increase engagement among SDs thereby increasing favorable outcomes for organizations and individual employees in the current times.
Originality/value
The study establishes job security and value congruence, as two critical yet cost-effective measures that today’s organization need to integrate into its human resources functions not just to boost employee engagement levels but also to control spiraling costs due to unintended turnover, employee’s resistance of organizational changes and employee ill-being. Future research avenues and practical implications have been discussed.

Abstract
Purpose
The study aims to identify and understand the underlying behavioral tendencies and motivations influencing investor sentiments and examines the relationship between these underlying factors and investment decisions during the COVID-19-induced financial risks.
Design/methodology/approach
The study uses the primary data and information collected from 300 Indian retail equity investors using a nonprobability sampling technique, specifically purposive and snowball sampling. This research uses the insights from Phuoc Luong and Thi Thu Ha (2011) and Shefrin (2002) to delineate behavioral factors influencing investment decisions. Structural equation modeling estimates the causal relationship between underlying behavioral factors and investment decisions during the COVID-19-induced financial risks.
Findings
The study establishes that the “Regret Aversion,” “Gambler’s Fallacy” and “Greed” significantly influence investment decisions, and provide a comprehensive understanding of how psychological motivations shape investor behavior. Notably, “Mental Accounting” and “Conservatism” exhibit insignificance, possibly influenced by the unique socioeconomic context of the pandemic. The research contributes to 35% of variance understanding and prompts the researchers and policymakers to tailor investment strategies aligned to these behavioral tendencies.
Research limitations/implications
The findings hold policy implications for investors and policymakers and provide tailored recommendations including investor education programs and regulatory measures to ensure a resilient and informed investment community in the context of India's evolving financial landscapes.
Originality/value
Theoretically, behavior tendencies and motivations have been strongly linked to investment decisions in the stock market. Yet, empirical evidence on this relationship is limited in developing countries where investors focus on risk management. To the best of the authors’ knowledge, this study is among the first to document the influence of underlying behavioral tendencies and motivation factors on investment decisions regarding retail equity in a developing country.

Abstract
Purpose
This paper aims to examine the mediating role of brand satisfaction and brand trust in brand equity antecedents and outcomes through an empirical investigation of brand equity elements.
Design/methodology/approach
A survey was conducted in Pune and Mumbai, two prominent cities of India. A structured questionnaire focussed on garnering responses on measuring brand equity antecedents and outcomes was circulated to the cell phone users. The questionnaire aimed to assess the role of two additional variables, namely, brand satisfaction and brand trust, in the existing and the conceptual model of brand equity (Keller, 2001). Based on the data analysis, a structural equations path and the mediating model were developed.
Findings
The findings of this study show that the new brand equity model is highly relevant in predicting brand equity as compared to the existing brand equity model (Keller, 2001). The brand equity mediation model clearly elucidates the role of brand trust and brand satisfaction.
Research limitations/implications
With reference to a theoretical contribution, the study broadens the existing hypothetical model of brand equity. The findings of this research provide a strategic and analytical model for brand managers to build brand relationships among their consumers.
Originality/value
The present study challenges the existing model of brand equity (Keller, 2001) and further makes an effort to fill in the gaps in the existing theoretical model of brand equity.

Abstract
The present chapter explores the topic of death in the context of contemporary New Delhi, India. Building upon what I chose to call an ‘expanded ethnography’, it explores the multiple ways in which sensory, visual and digital mediations and tools can help researchers address such an existentially delicate topic. Building on a mix of online visual ethnography (of computer screens and smartphones), of bodily/sensory practices, of sound recording and image-making, my research focussed on retirement homes and shelters amidst a bulging Indian metropolis. I engaged with subjects who, because of personal choices or family difficulties, have ended up finishing their lives in solitude amidst a city forced to co-live with the presence of death. Alternating between photographic portraits, filmic observations and moments of playful exchanges in front of a camera (with me as one of the objects portrayed) my method capitalizes upon the integration (and problematisation) of bodily (sensory and affective) as well as digital techniques. All together these different mediations have granted me access to different layers of connection to the topic of death in Delhi and also to my ageing guides/interlocutors.
