THIS paper describes a test method, developed on the Kirloskar AV‐1 (naturally aspirated) single‐cylinder diesel engine, for evaluating tendency towards detergency, ring sticking and accumulation of deposits in heavy‐duty type lubricating oils. The repeatability, reproducibility and the discriminating ability of the method is found to be good when the engine is run under the prescribed test method for 120 hours. This method is likely to be included in Indian Standard Specification for IC Engine Lubricating Oils, IS : 496. To finalize this test method, a correlation programme was also run between five laboratories. The results obtained correlate with the Petter AV‐1 test procedure when using a fuel containing 0–4% sulphur.

Carbon emission is one of the most important issues threatening the existence of the world. Mostly carbon emission induced climate change disrupts human and nature balance. Carbon emission occurs as a result of practices that are dependent on human activities or not. One of the actors causing carbon emissions is production companies. The companies are working toward reducing carbon emissions. However, although these efforts reduce carbon emissions in the short term, carbon emissions continue in the long term. Therefore, the present study aims to determine the importance of carbon emission in terms of sustainable economic development. Depending on this purpose, production companies in Chile were included in the scope of research for 1990–2019. Based on these data, the study has been tested by Toda Yamamoto causality analysis. Result shows that carbon emissions are not the primary cause of sustainable economic development. In this context, governments need to focus on other issues that have a stronger causal relationship with sustainable economic development. However, studies should be conducted to determine the importance of other activities of companies for sustainable economic development. Hereby, the amount of carbon emission will be reduced and deficiencies in factors affecting sustainable economic development will be identified.

The purpose in this paper is to develop a systematic literature review aiming to reveal innovation opportunities associated with the thematic collaboration and trust in the reverse logistics field.

The authors adopted a parallel analysis approach segregating the systematic literature review papers in two groups at NVivo®, collaboration and trust in the supply chain and collaboration and trust in reverse logistics, aiming to explore in the first group of papers insights for innovation on collaboration and trust in reverse logistics. The content analysis strategy was supported by the knowledge exchange theory described in Gravier et al. (2008).

Reverse logistics is hardly dissociated from broader sustainable supply chain management approaches, which make all considerations on collaboration and trust designed for such approaches valuable and valid for reverse logistics. Collaboration and trust concepts in supply chain and in reverse logistics contexts are quite similar, while collaboration/trust is mandatory for managing networks in sustainable approaches and in reverse logistics, as well. Downstream and upstream, the chain disruptive innovation business models may be developed between focal companies and returns system third-party logistics providers, fourth-party logistics providers or end-customers, in a business-to-customer collaboration approach. Several collaboration technologies are listed in three perspectives: knowledge sharing, knowledge generation and knowledge implementation.

This study uses a specific protocol for the systematic literature review, and due to inclusion and exclusion criteria, other protocols can provide different results. The strategy of analysis under the knowledge exchange perspective may give a type of result different from other perspectives.

This research systematizes the existing knowledge on the collaborations and trust, which is a priority basis for reverse logistics, providing insights to researchers and practitioners in the area and identifying an agenda for future studies.

By using exploratory mixed methods, this study aims to present the investigation of the existing situation of private off-campus student accommodation at the University of Allahabad (UoA) in Prayagraj city.

This study explored the geographical variability of student’s private rental housing in Prayagraj city of India through 721 responses from an online semi-structured questionnaire, together with 12 interviews. Moran’s I and LISA were used to determine spatial clustering of rents paid by male and female students.

Results of this study reveal prevalence of unregulated with poor quality of off-campus housing in general and expensive rents in the proximity of UoA.

Obtaining less responses from the female students was one of the important limitations.

A win-win strategy might be formulated with a mix of innovative solutions inclusive of public private partnerships and social economy solutions woven with need-based rental housing, rekindled as the affordable rental housing complexes after COVID-19 pandemic.

This study is highly beneficial to improve liveability in the student housing segment.

This paper develops extensive understanding on the potential student housing segment in the Indian cities. Additionally, this paper demonstrates weak coordination between the central government policies, educational administrators and municipal officials.

Personal financial management is gaining momentum in modern society, as it plays a vital role in shaping the financial behaviour of people looking forward to adequate financial well-being. Hence, people in general and the weaker sections of society in particular are expected to show desirable financial behaviour for achieving individual as well as societal well-being. The present study investigates the impact of socio-economic characteristics on the financial behaviour of migrant workers who have migrated to the state of Tamil Nadu. The primary data were collected using the interview schedule from 200 migrant workers selected using the snowball sampling technique. The results show that migrant workers have mediocre financial behaviour. Furthermore, it is also found that migrant workers’ financial behaviour is not influenced by their socio-economic characteristics, such as gender, age, marital status, family type, and family income. However, the level of education has a significant positive role in shaping the financial behaviour of the migrant workers. The study outlines the need for specially engineered financial education for migrant workers.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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).

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.

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.

This paper aims to analyse how financial literacy (FL) is conceptualised and operationalised in the Indian context.

A systematic literature review (SLR) was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) protocol. Thirty-six articles published between 2010 and 2020 were considered for analysis. The FL conceptualisation was examined based on knowledge, ability, skill, attitude and confidence elements. The FL operationalisation was analysed using the modified version of the Organisation for Economic Co-operation and Development’s (OECD) Programme for International Student Assessment (PISA) 2012 model for organising the domain for an assessment framework.

The findings indicate that, despite offering operationalisation details of the FL, 13 out of 36 studies did not include a conceptual definition of FL. Of the 23 studies that mentioned a conceptual definition, 87% are primarily focused on the “knowledge” element and only 39% have combined knowledge, ability/skill and attitude elements in defining FL. As in the developed countries, the Indian studies also preferred investment/saving-related contents in their FL measures. The volume of content focusing on the financial landscape is meagre amongst the FL measures used in India and developed countries. The survey instruments of most studies have been designed in the individuals’ context but have failed to measure the extent to which individuals apply the knowledge in performing their day-to-day financial transactions. Further, it was found that 20 out of 36 studies did not convert the FL level of their target groups into a single indicator or operational value.

To the best of our knowledge, this is the first study that explores the FL’s assessment practices in India. Further, this study offers new insights by comparing the contents of FL measures used in Indian studies with those used in developed countries.

This paper reviews the literature on zombie firms to provide a holistic view by delineating their formation, impact, widespread nature, prevention and policy implications.

This paper uses a systematic literature review methodology, in which 76 papers published in journals ranked on the Australian Business Deans Council (ABDC) 2022 list were reviewed. The study period was from 2000 to 2022.

Among the main findings, the widespread problems of zombie firms were evident. The authors found that consistent support, either in the form of government grants or a weak financial framework, was responsible for their formation. The suboptimal performance of factors of production, depressed job creation, low innovation and overall negative impact on economic activity are the consequences of zombification. This can be controlled by ensuring better bankruptcy codes, focused on government assistance, technology use and better due diligence by banks.

This review serves as a reference point for future researchers as a cohesive and holistic study presenting a full picture of the problem, so that the proposed solutions are robust and tenable.

This review is among the initial attempts to comprehensively study published work on zombie firms in terms of analyzing their region-specific nature, with an emphasis on definition, causes, impact and prevention.
