Reverse supply chain (RSC) is one of the ways to handle product returns efficiently. Recovery of residual value from product returns also helps in achieving sustainability. Its successful implementation requires coordination among all the channel members involved in the activities, from the acquisition to collection to the disposition of returned products. This article aims to review the literature about coordination issues in the RSC.

A systematic literature review of 151 articles published during 2004–2021 is carried out. Theory, context and methodology (TCM) framework of the literature review is used to identify the research gaps for future research directions.

This study identifies the characteristics of RSC coordination. It includes channel structures; coordination mechanisms; performance measuring parameters; the methodology applied and explored industries. The review shows that game-theoretical modeling in RSC coordination is the most commonly used method to coordinate the channels. It was found that issues like disruption, fairness and corporate social responsibility are not explored in-depth and offer much potential for future research.

There are very limited studies on coordination issues in the RSC. The proposed articles add value by considering RSC issues from different strategic, government, consumers' behavior and functionality decision-making point of view.

The study aims to investigate the consumers' behavioral intention toward green hotels. The tendency of individuals to afford green hotels is further escalating with progressing coronavirus disease-2019 (COVID-19) pandemic recurring waves. The increased worry of consumers toward health, hygiene and the climate is acquiring momentum and transforming how consumers traditionally perceive green hotels.

The study has recommended an integrated framework incorporating various research fields as attitude-behavior-context theory, theory of planned behavior (TPB) and moderating influences to study the associations among the antecedents of consumers' behavioral intention toward green hotels. The study comprised the participation of 536 respondents residing in the Delhi and National Capital Region (NCR) of India. The data analysis strategy involved the use of structural equation modeling (SEM) analysis to test the proposed research framework.

The results and findings of the study indicated a significant influence of fear and uncertainty of the COVID-19 pandemic and environmental concern on green trust. The results also revealed the considerable impact of green trust on willingness to pay premium, attitude and subjective norms, which significantly influenced behavioral intention. The analysis also revealed the moderating influence of environmental concern in the relationship of green trust and behavioral intention.

The study has recommended significant theoretical. The theorists may use this research framework to analyze better the transforming consumer behavior trends toward green hotels in the ongoing fearful and uncertain COVID-19 pandemic scenario.

The study has recommended significant managerial implications. The industry practitioners may also utilize the framework to sustain the hotel business and bring new strategic insights into practice to combat the impact of the pandemic and simultaneously win consumers' trust in green hotels.

Although the researchers have previously emphasized consumers' intention toward green practices embraced by hotels, the impact of the COVID-19 pandemic on the green hotel industry gained noticeable attention from researchers. Furthermore, there is a scarcity of literature providing insights on the behavioral dynamism of hotel customers' trust, attitude and willingness to pay for green hotels during the repetitive waves of the COVID-19 pandemic. The study will support the existing literature gap by enlightening the associations among the various antecedents of green hotels' behavioral intention, COVID-19 and environmental concern.

The present study aims to demonstrate the performance assessment of flexible pavement structure in probabilistic framework with due consideration of spatial variability modeling of input parameter.

The analysis incorporates mechanistic–empirical approach in which numerical analysis with spatial variability modeling of input parameters, Monte Carlo simulations (MCS) and First Order Reliability Method (FORM) are combined together for the reliability analysis of the flexible pavement. Random field concept along with Cholesky decomposition technique is used for the spatial variability modeling of the input parameter and implemented in commercially available finite difference code FLAC for the numerical analysis of pavement structure.

Results of the reliability analysis, with spatial variability modeling of input parameter, are compared with the corresponding results obtained without considering spatial variability of parameters. Analyzing a particular three-layered flexible pavement structure, it is demonstrated that spatial variability modeling of input parameter provides more realistic treatment to property variations in space and influences the response of the pavement structure, as well as its performance assessment.

Research is based on reliability analysis approach, which can also be used in decision-making for quality control and flexible pavement design in a given environment of uncertainty and extent of spatially varying input parameters in a space.

This study aims to perform a systematic literature review to organize the abundance of information on employee relations (ER) and sustainable organizations. Moreover, this study identifies the research gaps by investigating the review of ER’ mediating and moderating variables and the relationship between ER and sustainable organizations.

This study is based on the systematic literature review methodology involving 257 studies in the final stage. The Scopus and Google Scholar databases with search criteria “employee relations” and “employee relations and sustainable organization” were used to achieve the research objective. After applying inclusion and exclusion criteria, researchers come to the distribution of the articles based on the subthemes, geographical region, types of methods, top authors with affiliation and complete research articles based on the citation. In the final stage, this study concluded with the conceptual model comprising mediators and moderators of ER as well as the mediating and moderating variables of the relationship between ER and sustainable organizations.

The reviewed literature shows that employee relation is an optimal strategy for retaining employees via proper disclosure of human resources (HRs) and ER Index. This study included the top six publishers, namely, Emerald, Elsevier, Sage, Springer, Taylor and Francis and Wiley Online Library, to do an exhaustive review on a specific topic. The findings indicate that after COVID-19, the ER index, HR disclosures and the sustainability of ER are among the new and required paradigm shifts needed to manage a crisis impact and perform productively. The mediator and moderator variables that can improve employee–employer relationships are organizational trusts, organizational justice, perceived job satisfaction, organizational structure and firm ownership. On the other hand, variables that mediate and moderate the relationship between ER and sustainable organizations are organizational climate, organization trust, organization culture, perceived organization support, psychological empowerment, firm ownership, leadership behavior and attitude, respectively. The findings concluded that harmonious and cordial ER are pertinent in building sustainable organizations and accomplishing organizational goals.

The mediating and moderating variables that have been identified can be helpful for enthusiastic researchers in contributing to empirical research. Practitioners and managers can use the findings in making an effective organizational model that develops good employee–employer relationships and helps create a culture of trust and harmony. This study focuses on exploring the variables of ER, which strengthens employee–employer relationships and supports organizations to stay agile and attain sustainability to endure in the future.

This study insights on the specific mediating and moderating variables of ER and sustainable organizations. Till date, studies exploring constructs of ER and sustainable organizations are still in deficit. Better employee relation reflects and leads to a more resilient organization. Future researchers should explore the connection between pandemics and ER which is done insufficiently in the present time.

The COVID-19 pandemic has had serious and far-reaching consequences on every aspect of human life. As various countries went into lockdown, hospitality and tourism was badly affected and this has had an impact on hospitality and tourism education too. This paper aims to assess the impact of the pandemic on hospitality and tourism education in India and the effectiveness of mitigation strategies in support of the industry. The study also proposes recommendations for resilience-building.

A pilot survey using semi-structured interviews was conducted and followed by a detailed questionnaire-based survey of industry representatives and educators. Selected industry leaders were also interviewed to understand the industry perspective on the pandemic, the “new normal” and the expectations of post pandemic graduates. The study focuses on four main areas – (1) existing interrelationships between industry and academia, (2) the efficiency of Internet-based education during the pandemic, (3) the “new normal” and the expectations of graduates and (4) recommendations for resilience-building.

There is a perceived gap between academia and industry that needs to be bridged. We found that the pandemic is seriously affecting education with challenges ranging from technological issues, disparities and reduced enrolments to student behavioural issues. Most impacted was the practical training component in operational areas and especially in food production and services. It is now clear that education needs a shift in focus from the more traditional, operational aspects of hospitality and tourism to technological awareness, knowledge and soft skills development. The research also identified a need for better two-way communication and information exchange between industry and academia. In fact, the lessons learnt from the pandemic need to be communicated from industry to academia. This is important given that industry expects graduates to be adaptive, compassionate, able to multi-task, familiar with the principles of crisis management and proficient with technology.

The study analyses possible long-term effects and implications for the workforce of the future as the industry struggles to respond to the pandemic. The study also suggests possible avenues and methods for industry and academia to form more symbiotic relationships and become more resilient.

The purpose of this paper is to identify the factors that influence hospitals’ selection by health-care insurers in India and to establish a hierarchical model representing the relationship among different factors and their influence on the entire scenario.

A survey with a set of questionnaires was conducted with different health-care insurer executives of reputed health insurance companies. The data has been gathered by using a five-point Likert scale. Their opinions were converted into a reachability matrix and an interpretive structural modeling was constructed. The final results obtained were verified by using fuzzy Matriced Impacts Croises-Multiplication Applique and Classement analysis.

The results suggested three key driving factors, National Accreditation Board for Hospitals & Healthcare Providers accreditation of the hospital, purchasing power of people in the region and national and international recognition of the hospital among the eleven factors selected for the study.

The research mainly focuses on the health insurance benefits provided by privately owned insurance companies and do not comment on any government’s mass health insurance scheme.

With a small proportion of people under the umbrella of health insurance in India, these factors will assist and expedite insurer’s effort to penetrate deep into rural and urban areas enhancing availability and escalating affordability.

This paper presents key factors responsible for better coordination between health-care systems and insurance companies.

Surface properties (smooth or roughness) play a critical role in controlling the wettability, surface area and other physical and chemical properties like fluid flow behaviour over the rough and smooth surfaces. It is reported that rough surfaces are offering more significant insights as compared to smooth surfaces. The purpose of this study is to examine the effects of surface roughness in the diverging channel on physiological fluid flows.

A mathematical formulation based on the conservation of mass and momentum equations is developed to derive exact solutions for the physical quantities under the assumption of low Reynolds numbers and long wavelengths, which are appropriate for biological transport scenarios.

The results reveal that an increase in surface roughness reduces axial velocity and volumetric flow rate while increasing pressure distribution and turbulence in skin friction.

These findings offer valuable insights for biological flow analysis, highlighting the effects of surface roughness, non-uniformity of the channel and magnetic fields.

These findings are very much applicable for designing the pumping devices for transportation of the fluids in non-uniform channels.

This study examines the impact of surface roughness on the peristaltic pumping of viscoelastic (Jeffrey) fluids in diverging channels with transverse magnetic fields.

The purpose of this paper is to examine the magneto hydrodynamic flow and heat transfer of nanofluids over a permeable wedge based on engine oil which is under the effects of thermal radiation and convective heating.

The equations governing the flow are transformed into differential equations by applying similarity transformations. Keller box method is used to bring out the numerical solution.

The discovery interprets that temperature as well as the velocity of Ag-engine oil nanofluids are more noticeable than Cu-engine oil nanofluids. Thermal boundary layer increases for radiation parameter as well as Biot number. Fluctuations of co-efficient of drag skin friction as well heat transfer rate at the wall are also tested.

Till now, no numerical studies are reported on the heat transfer enhancement of the permeable wedge under thermal radiation on engine oil nanofluid flow by considering convective heating.

The purpose of this paper is to identify and prioritize the lean implementation (LI) barriers in the context of labor intensive Indian ceramic industries through a statistically reliable and validated model.

In this study, LI barriers are identified through a comprehensive review of relevant literature and discussions held with academicians/practitioners. Identified barriers, thereafter, are evaluated with Cronbach's alpha values using a statistical tool. The interpretive ranking process (IRP) methodology is applied for ranking of the barriers with reference to the measurable performance indicators.

The study identified highly relevant barriers of Indian ceramic industries. Further, these barriers were compared with performance measures through a cross-interaction matrix developed in the IRP model. The model highlights the analysis of dominance relationship of different barriers. Moreover, the result shows that top management commitment and leadership is at the top of the model, followed by lack of training opportunity and skills, and resistance to change and adopt innovations indicating their strongest driving power in LI.

This model may enable the firms to understand the LI barriers and come up with sensible implementation program. Further, the correlation results among the barriers will provide insights in mitigating the hurdles of lean manufacturing (LM) implementation in the industries.

This study empirically develops a model through the IRP for the barriers in LM implementation. From the reported literature, it appears that the application of IRP is very rare in ceramic industries in India. The analysis and prioritization of LI barriers may help practitioners to plan strategies to implement lean in a selected domain.

The purpose of the present work is identification and prioritization of barriers to Lean Six Sigma (LSS) implementation in Indian manufacturing industries in the context of Industry 4.0 (I4.0) to surmount the impediments in the path of successful implementation.

In total, 27 barriers identified through critical review of literature and expert's opinion are evaluated with Cronbach's alpha values including item-total correlations or corrected item-total correlations (CITC) using statistical tool. Finally, 20 barriers were analyzed and ranked employing Fuzzy Analytical Hierarchy Process (FAHP).

The study depicts that “Lack of leadership, advisory and monitoring,” “Lack of clarity about economic benefits” and “Lack of integration of LSS with smart tools/I4.0” are potential barriers to drive the path for proper implementation of LSS in Industry 4.0 with due consideration of its technologies in Indian manufacturing industries.

The study provides better knowledge platform for academicians and researchers about hidden aspects of LSS implementation barriers in view of advanced manufacturing technologies. This research will help the practitioners to design their business plans in implementing new quality improvement tools to get advantage in current competitive environment.

The barriers are selected based on literature and opinion from industry and academic experts. Five major criteria are decided after incorporating inputs. The ranking of the barriers is attained by well standard mathematical technique. This will enable the practitioners to design strategies to eliminate the hindrances in order to shape the right path for effective implementation of LSS approach in view of advanced manufacturing technologies.
