Abstract
Purpose
This paper aims to report findings for the following question, “What is the nature of high school students’ identity exploration as a result of exploring the role-possible selves of an environmental scientist and urban planner in a play-based course?” Projective reflection (PR) is served as a theoretical and methodological framework for facilitating learning as identity exploration in play-based environments.
Design/methodology/approach
From 2016-2017, 54 high school freshmen students engaged in virtual city planning, an iteratively refined course that provided systematic and personally relevant opportunities for play, curricular, reflection and discussion activities in Philadelphia Land Science, a virtual learning environment (VLE) and in an associated curriculum enacted in a science museum classroom. Participants’ identity exploration was anchored in targeted role-possible selves in science, technology, engineering and mathematics: environmental science and urban planning through in-game and in-class activities. This role-playing was made intentional by scaffolding students’ reflection on what they wanted to be in the future while thinking of their current selves and exploring novel role-possible selves.
Findings
In-game logged data and in-class student data were examined using quantitative ethnography (QE) techniques such as epistemic network analysis. Whole-group statistical significance and an illustrative case study revealed visual and interpretive patterns of change in students’ identity exploration. The change was reflected in their knowledge, interest and valuing, self-organization and self-control and self-perception and self-definition (KIVSSSS) in relation to the roles explored from the start of the intervention (starting self), during (exploring role-possible selves) and the end (new self). The paper concludes with directions to advance research on leveraging role-playing as a mechanism for fostering identity exploration in play-based digital and non-digital environments.
Originality/value
This paper leveraged VLEs such as games as forms of play-based environments that can present players with opportunities for self-transformation (Foster, 2014) and enculturation (Gee 2003; Shaffer, 2006) to support learner agency and participation in a constantly changing society (Thomas and Brown 2011). The authors introduce and apply novel theoretical and methodological approaches to the design and assessment of play-based environments and address pertinent gaps in the emergent area of learning and identity in VLEs

Abstract
Purpose
The objective of this paper is to employ a model to expand the literature's comprehension of the organisational citizenship behaviour (OCB) phenomenon in the Indian banking sector. The authors examine OCB as a mediator of the relationship between job embeddedness (JE), self-efficacy (SE) and organisation effectiveness (OE). The authors also verify the moderating role of affective commitment (AC) on the JE, SE and OE relationship.
Design/methodology/approach
Data for the purpose of this paper are collected from 568 employees in 89 branches of banks located in North and Central India using a survey questionnaire. The data collected were analysed using structural equation modelling (SEM).
Findings
The findings confirm the positive association between JE, SE and OE. The results also suggest that OCB mediates the association between the independent and dependent variables. Furthermore, the authors observed that AC moderates the OCB and OE relationship.
Practical implications
The results of this examination will assist the employees to realise the substance of OCB in directing their performance towards OE. This investigation will inspire bank managers to notice that employee readiness to put in extra effort in a bank is primarily the effect of apt individual characteristics, namely JE and SE, that can be shaped and developed. Furthermore, this study draws the attention of bank managers towards the significance of AC, as an essential phenomenon to emotionally attach the employees to their organisation.
Originality/value
This study contributes to the existing literature on OCB by examining how OCB leads to desired outcomes and the conditions that promote the effect of OCB. The authors address these questions by building on a more contemporary perspective, i.e., PsyCap.

Abstract
Purpose
The purpose of this paper is to study the influence of inflated energy prices on the capital structure of Indian manufacturing corporations and to investigate whether the capital structure of Indian firms is driven by demand shocks or supply shocks during the study period.
Design/methodology/approach
After conducting a thorough review of the capital structure and inflation-based research studies, panel data-based regression model and correlation matrix have been used as statistical tools for Indian manufacturing sector available with the Centre for Monitoring Indian Economy Prowess database.
Findings
The results suggest that variables like the presence of inflated energy prices had adversely influenced the capital structure of Indian corporations. Not only this, the study also highlights that factors pertaining to the demand shock had induced Indian corporations to have higher debt levels in the capital structure.
Practical implications
This study has laid some ground work to explore the influence of inflation on capital structure of Indian firms upon which a more detailed evaluation could be based.
Originality/value
To the best of the authors’ knowledge, this study is the first that explores the influence of inflated energy prices on the capital structure of manufacturing firms in India by using the most recent data.

Abstract
Scholarly works on sex work and sex workers are mostly confined to discourses on human trafficking and the incidence of HIV/STIs among sex workers. Although crucial, this restricted focus has neglected the reality that sex workers are a diverse community, and while their challenges may appear to be linked at first glance, they differ greatly. While extensive research has been conducted on sex workers working in more open settings like brothels, hotels, and streets, there is a scarcity of research on sex workers working in more private spaces, such as, for instance, their own homes. Within the hierarchy of sex workers, home-based sex workers (HBSWs) among the indoor sex workers dominate commercial sex transactions. However, they are often overlooked due to their covert nature and invisible landscape. This chapter addresses the knowledge gap by examining the work lives and conditions of home-based female sex workers (FHBSWs) in Punjab. The study analyzes the complex lives of sex workers who use their home as both a family unit and a workplace. A detailed analysis of the risks and vulnerabilities they face in their daily lives and their coping strategies is also examined in this chapter. The study points out that although working from home may have positive outcomes for sex workers, the integration of sex work into the home environment exposes them to several challenges. Hence, the study emphasizes the need for tailoring interventions for sex workers who operate in different physical environments so that their unique needs and challenges are well addressed.

Abstract
Purpose
The authors intend to assess the village health sanitation and nutrition committees (VHSNC) on six parameters, including their formation, composition, meeting frequencies, activities, supervisory mechanisms and funds receipt and expenditures across nine districts of the three states of India.
Design/methodology/approach
The cross-sectional study, conducted in the states of Uttar Pradesh (five districts), Odisha (two districts) and Rajasthan (two districts), used a quantitative research design. The community health workers of 140 VHSNCs were interviewed using a semi-structured questionnaire. The details about the funds' receipt and expenditures were verified from the VHSNC records (cashbook). Additionally, the authors asked about the role of health workers in the VHSNC meetings, and the issues and challenges faced.
Findings
The average number of members in VHSNCs varied from 10 in Odisha to 15 in Rajasthan. Activities were regularly organized in Rajasthan and Odisha (one per month) compared to Uttar Pradesh (one every alternate month). Most commonly, health promotion activities, cleanliness drives, community monitoring and facilitation of service providers were done by VHSNCs. Funds were received regularly in Odisha compared to Rajasthan and Uttar Pradesh. Funds were received late and less compared to the demands or needs of VHSNCs.
Research limitations/implications
This comprehensive analysis of VHSNCs' functioning in the selected study areas sheds light on the gaps in many components, including the untimely and inadequate receipt of funds, poor documentation of expenditures and involvement of VHSNC heads and inadequate supportive supervision.
Originality/value
VHSNCs assessment has been done for improving community health governance.

The purpose of this study is to examine the influence of earnings management during initial public offerings on the listing day returns.
Abstract
Purpose
The purpose of this study is to examine the influence of earnings management during initial public offerings on the listing day returns.
Design/methodology/approach
The study collected data for 511 Indian IPOs that came between April 2003 and March 2019 for calculating earnings management. On the basis of the Cross Sectional Modified Jones Model 1995, the paper presents three proxies of earnings management as discretionary accruals (DA), discretionary current accruals (DCA) and discretionary long-term accruals (DLA). The study further used correlation and multiple regression analysis to assess the impact of earnings management on listing day returns.
Findings
The findings show that earnings management and listing day returns vary through issue-year and industry-type. Apart from it, the study reveals a greater contribution of short-term accruals in earnings management on the basis of higher DCA values. It also discloses that the aggregate level of earnings management (DA) influences listing returns, whereas DCA and DLA separately have no impact on the listing day returns of the Indian IPOs.
Research limitations/implications
The findings are useful to potential investors and analysts to observe, assess and understand the quality of financial reports that are based on fallacious disclosure of accounting figures. The study also reflects the efficacy of Indian regulatory norms for IPOs in constraining earnings management and underpricing, thus providing meaningful insight to the policy makers and the regulators.
Originality/value
This study is distinguished by its focus on determining the influence of earnings management on listing day returns in Indian IPOs by using three earnings management proxies.

Abstract
Purpose
This study aims to examine earnings management around initial public offerings (IPOs) in India. It also explores the influence of issue characteristics on earnings management around the IPOs.
Design/methodology/approach
A sample of 511 IPOs that came during April 2003-March 2019 is studied for calculating earnings management for pre-issue, issue and post-issue years. Using Cross-Sectional Modified Jones Model, the paper presents earnings management on the basis of three proxies i.e. discretionary accruals, discretionary current accruals and discretionary long-term accruals. The influence of issue characteristics on earnings management practised around the IPOs is also observed through correlation and multiple regression analysis.
Findings
The paper finds that earnings management is abnormally high during the issue year compared with pre-issue and post-issue years. It also unveils that profitability, premium, age, and size of the issuer significantly determine the level of pre-issue and issue year earnings management practised by Indian IPO issuers.
Research limitations/implications
The findings are useful to stakeholders (potential investors, analysts and regulators) to observe, assess and understand the quality of financial numbers that are based on fallacious disclosure of accounting figures. It provides insight into the possibilities of managed earnings around the issue that could influence investors’ decision-making. Further, the study reflects the efficacy of Indian regulatory norms for IPOs.
Originality/value
To the authors’ knowledge, it is the only Indian study that had used an extensive data set of about two decades to calculate earnings management during pre-issue, issue and post-issue years. The uniqueness of the study further lies in three proxies of earnings management representing short-term and long-term accruals. Moreover, it is the first study to observe the influence of IPO issue characteristics on earnings management.

Abstract
Purpose
A variety of biomass plantations are being raised for energy production. This case study is on energy production potential of seasonal oil bearing crops in India. These crops have the advantage of producing oil (liquid fuel) as well as biomass as agro residue (solid fuel). The purpose of the study is to estimate total energy yields of oil bearing crops and compare with other types of energy plantations. Also oil bearing crops bioaccumulate metals and thus phytoremediate soil. This provides scope for waste water irrigation.
Design/methodology/approach
Relevant published papers on energy production by raising oil bearing crops have been analyzed. The effect of waste water irrigation and agronomic practices on increasing productivity is given special attention.
Findings
It is shown that the seasonal oil bearing crops such as castor have a high potential to generate energy and this is comparable to energy produced by many perennial grasses. The energy yields of castor under irrigated condition was 196×103 MJ/ha and this is comparable to the reed canary grass which yields 195×103 MJ/ha. Some of the oil bearing crops are also super accumulators of certain toxic metals.
Research limitations/implications
In this study, only all the accessible papers on the topic could be analyzed.
Practical implications
This case study indicates that raising oil bearing crops such as castor using waste water has many advantages which include high energy yields, utilization of waste water for productive purpose and phytoremediation of soil.
Originality/value
The comparison made between various types of energy crops for their energy generation is an original contribution. Findings of economic and environmental benefits by waste water irrigation are also of value.
