Abstract
Purpose
To explore the mediating role of altruism in the relationship between self‐sacrifice and transformational leadership, and to look at the effect of all three on followers' collective identity and perceptions of unit performance.
Design/methodology/approach
For Study 1, survey responses were collected from 127 managers in India. They answered questions on their leader's self‐sacrifice, altruism, and transformational leadership, and on their own collective identity and perceptions of unit performance. Study 2 used a scenario experiment and 161 students to manipulate self‐sacrifice and altruism and measure their effects on transformational leadership, collective identity and perceived unit performance.
Findings
It is possible to distinguish between self‐sacrifice and altruism empirically. Altruism mediates the relationship between self‐sacrifice and transformational leadership. Transformational leadership is positively related to followers' collective identity and perceived unit performance.
Research limitations/implications
Common source bias may have affected the findings. Use of student sample in Study 2 limits the generalizability of findings.
Practical implications
Other‐orientedness (altruism) of a manager enhances transformational leadership, which in turn leads to higher collective identity and perceived unit performance. Self‐sacrifice could be a good starting point in this chain of events.
Originality/value
Studies have shown that self‐sacrifice enhances transformational leadership. This paper highlights the mediating process through altruism. This is the first empirical study to look at the relationship between altruism and transformational leadership. This is also the first study to look at self‐sacrifice and altruism simultaneously.

Abstract
Purpose
Electrical discharge machining (EDM) of hard materials like NiTi 60 alloys is important as it finds application in different sectors of engineering such as automobile, aircraft, biomedical, oil industries, etc.
Design/methodology/approach
The first target of this investigation is to determine the effect of process parameters such as current, voltage, pulse on time and pulse off time on the material removal rate (MRR), surface roughness (SR) and white layer formation (WLT) for NiTi 60 smart material alloy. The secondary aim is to identify the presence of surface integrity parameters such as cracks, WLT, microvoids, globules and debris formation by using the scanning electron microscopy technique and with the use of ImageJ software for die sink EDM machining of NiTi 60 alloy.
Findings
The results reveal that current is significant for MRR, voltage and current influence SR, and for WLT, voltage is a significant factor. The experimentation study also shows the generation of oxide and carbide layers on the machined surface, which were evident with the use of the X-ray diffraction technique. The presence of these oxide and carbide layers causes to form WLT on the machined surface and thereby increases the hardness of the machined surface.
Originality/value
Hardness test was performed with Vickers hardness tester, which gives evidence for the increase in hardness of machined surface due to the generation of WLT.

Abstract
Purpose
This study aims to experimentally investigate the influence of considered process parameters, i.e. pulse on time, pulse off time, peak current and gap voltage, on tool wear rate (TWR) in electrical discharge machining (EDM) of iron (Fe)-based shape memory alloy (SMA) through designed experiments. The parametric optimization for TWR has also been attempted using the desirability approach and genetic algorithm (GA).
Design/methodology/approach
The response surface methodology (RSM) in the form of Box–Behnken design has been used to scheme out the experiments. The influence of considered process inputs has also been observed through variance analysis. The reliability and fitness of the developed mathematical model have been established with test results. Microstructure analysis of machined samples has also been evaluated and analyzed using a scanning electron microscope (SEM). SEM images revealed the surface characteristics such as micro-cracks, craters and voids on the tool electrode surface. SEM images provide information about the surface integrity and type of wear on the surface of the tool electrode.
Findings
The input parameters, namely, pulse on time and pulse off time, are major influential factors impacting the TWR. High TWR has been reported at large pulse on time and small pulse off time conditions whereas higher TWR is reported at high peak current input settings. The maximum and minimum TWR values obtained are 0.073 g/min and 0.017 g/min, respectively. The optimization with desirability approach and GA reveals the best parametric values for TWR i.e. 0.01581 g/min and 0.00875 g/min at parametric combination as pulse on time = 60.83 µs, pulse off time = 112.16 µs, peak current = 18.64 A and gap voltage = 59.55 V, and pulse on time = 60 µs, pulse off time = 120 µs, peak current = 12 A and gap voltage = 40 V, correspondingly.
Research limitations/implications
Proposed work has no limitations.
Originality/value
SMAs have been well known for their superior and excellent properties, which make them an eligible candidate of paramount importance in real-life industrial applications such as orthopedic implants, actuators, micro tools, stents, coupling, sealing elements, aerospace components, defense instruments, manufacturing elements and bio-medical appliances. However, its effective and productive processing is still a challenge. Tool wear study while processing of SMAs in EDM process is an area which has been less investigated and of major concern for exploring the various properties of the tool and wear in it. Also, the developed mathematical model for TWR through the RSM approach will be helpful in industrial revelation.

Abstract
Purpose
The present era, in its pursuits for economic development, has equated development with affluence. The balance between economic development and using natural resources for the purpose needs to be solved. The previous civilisations became extinct less because of foreign invasions and more due to neglecting the ecological environment. In the same way, this civilisation is also digging its own grave.
Need for the Study
After reviewing the available literature, it is proposed to study in the context of the Punjab state of India. The pattern of receipts and expenditures of funds utilised for ecological upgradation emphasises evaluating the performance of the funds utilised for ecological improvement. Furthermore, most of the study has concentrated on the experiences of developed economies. In contrast, there have been minimal studies explicitly addressing the circumstances of emerging countries.
Methodology
The study is confined to Punjab and is based on secondary data. The Punjab government collected the annual data on expenditures and receipts from the last 10 years. The nature of the receipts and expenditures for the entire 11 sectors is determined through descriptive statistics. Moreover, the regression model and compound annual growth rate with the help of semi log model have been used to examine the extent of government funds. A line chart shows the pattern of government funding.
Practical Implications
The government can implement changes or create new environmental protection policies based on the results. As a whole, the research contributes to better environmental protection policy. The study concludes that a thorough examination of money flow in and out is essential.

Abstract
Purpose
As an emerging technology, Radio Frequency IDentification (RFID) and blockchain have the potential to disrupt many areas of business and social structure. However, it is loaded with significant technical, social, legal, financial and ethical complications that bring difficulty in its widespread use within the public distribution system (PDS). This research aims to analyze the barriers to integrated RFID and blockchain adoption in developing countries' PDS. Furthermore, this study also aims to validate the proposed framework against the Indian PDS.
Design/methodology/approach
The proposed framework consists of 10 potential barriers to integrated RFID and blockchain adoption. To identify the barriers, this study referred to the extant literature followed by consultations with domain experts. This study prepared the DEMATEL-based questionnaires, collected the data from four domain experts and analyzed them using an integrated Grey-DEMATEL approach.
Findings
The obtained results provide a precise list of barriers and the correlations among them. From the results, it is concluded that the unavailability of a skilled workforce at affordable cost, lack of knowledge about privacy level and unclear return on investment and benefits are the most critical blockchain adoption barriers in the context of Indian PDS.
Originality/value
This research proposes a framework consisting of 10 integrated RFID and blockchain adoption barriers in relation to Indian PDS. It also proposes a method for analyzing causal interrelationships between the barriers while allowing for data input from domain experts. Consequently, the framework is capable of coping with experts' biases and data scarcity.

Abstract
Purpose
Holy cities in India are seeing tremendous gentrification. This study aims to investigate the effect of the changing lifestyle of people towards spirituality and the changing lifestyle's impact on consumer buying behavior on properties in Indian holy cities which has not been studied anecdotally.
Design/methodology/approach
The research is exploratory in nature. A questionnaire has been sent to collect primary data through SurveyMonkey. Simple random sampling was used to collect a sample of 450 respondents which was also verified using G* software. The data were analyzed using descriptive statistics and partial least square–structured equation modeling (PLS-SEM).
Findings
Findings obtained through the structural model using bootstrapping technique suggest that intrinsic and extrinsic factors are attracting tourists leading to an increase in the demand for real estate in holy cities.
Research limitations/implications
The research findings may vary as per the cultural differences and belief in spirituality, which is subject to perceptual biases in different holy cities.
Practical implications
The traditional determinants of property buying behavior are considered inadequate to attract real estate investments. The inclusion of these behavioral aspects – intrinsic and extrinsic factors may improve the investment inflows in India.
Social implications
Spirituality connects to the concept of behavioral real estate, where the decision to buy property is largely affected by the emotional attachment of people.
Originality/value
This research adds value to fill the gap by finding out the latent determinant – emotional reasons impacting transnational gentrification in India.
