Abstract
Purpose
Aero-engine exhaust plume length can be more than the aircraft length, making it easier to detect and track by infrared seeker. Aim of this study is to analyze the effect of free stream Mach number (M∞) on length of potential core of plume. Also, change in infrared (IR) signature of plume and aircraft surface with variation in elevation angle (θ) is examined.
Design/methodology/approach
Convergent divergent (CD) nozzle is located outside the rear fuselage of the aircraft. A two dimensional axisymmetric computational fluid dynamics (CFD) study was carried out to study effect of M∞ on potential core. The CFD data with aircraft and plume was then used for IR signature analysis. The sensor position is changed with respect to aircraft from directly bottom towards frontal section of aircraft. The IR signature is studied in mid wave IR (MWIR) and long wave IR (LWIR) band.
Findings
The potential plume core length and width increases as M∞ increases. At higher altitudes, the potential core length increases for a fixed M∞. The plume emits radiation in the MWIR band, whereas the aerodynamically heated aircraft surface emits IR in the LWIR band. The IR signature in the MWIR band continuously decreases as the sensor position changes from directly bottom towards frontal. In the LWIR band the IR signature initially decreases as the sensor moves from the directly bottom to the frontal, as the sensor begins to see the wing leading edges and nose cone, the IR signature in the LWIR band slightly increases.
Originality/value
The novelty of this study comes from the data reported on the effect of free stream Mach number on the potential plume core and variation of the overall IR signature of aircraft with change in elevation angle from directly below towards frontal section of aircraft.

Abstract
Theoretical basis
This case uses concepts from Korten’s strategies of development-oriented four generations of non-government organizations (NGOs) and social psychology such as stereotypes, prejudices and actions to explain the social phenomenon. In furtherance, the case presents Aristotle’s approach to creating a message for masses that include use of ethos, pathos and logos. Stood’s (2017) narrative, engagement and technology (NET) model of social leadership was used to analyse the characteristics of social leaders.
Research methodology
Prima facie the case was developed from primary sources i.e. interviewing with Ashish Thakur. Literature from secondary sources was obtained to make teaching notes. List of references is presented towards the end that depicts the use of textbooks, research papers, websites and blogs. This case was tested in the classroom with MBA students learning business communication.
Case overview/synopsis
The case dealt with the challenges of an NGO that included conducting respectful last rites of unclaimed dead bodies. As the NGO grew, Ashish Thakur, the initiator of Moksh started facing resource management challenges, namely, volunteer induction, fundraising and managing non-human resources. These issues are deeply embedded in several social stereotypes about dead bodies. Learning covers strategies of four generations of NGO development, a NET model of social leadership, breaking social stereotypes related to dead bodies and last rites (necrophobia), designing social communication and opportunity to assess faulty rationalizations and do critical thinking around the socio-religious practices.
Complexity academic level
This case is intended to be used for the students of the social leadership or social entrepreneurship, social psychology, business communication or communication skills, organizational behaviour, advertising and social media.

Abstract
Purpose
This study aims to combine the theory of planned behave or (TPB) and the motivational framework to extend the research on online knowledge sharing (OKS) in an organization by exploring the factors that drive the knowledge sharing intentions (KSI) of posters and lurkers.
Design/methodology/approach
A field survey with 501 employees in Vietnamese telecommunication companies is used to collect the data and a structural equation modeling approach with AMOS 25.0 is used to test all the hypotheses.
Findings
Attitudes toward OKS and subjective norms influence online KSI for both posters and lurkers. Self-enjoyment has a stronger effect on the attitudes toward OKS for posters than lurkers. Self-efficacy, reciprocity and rewards only affect posters and not lurkers.
Research limitations/implications
This study uses self-efficacy and self-enjoyment to represent intrinsic motivation and reciprocity and rewards for extrinsic motivation. Future research may use additional motivational factors to provide additional insights.
Practical implications
Managers should pay greater attention to subjective norms and attitudes toward knowledge sharing to motivate all the employees to share knowledge with each other to improve organizational performance.
Originality/value
This is the first study to combine TPB with the motivational framework to explore the factors that drive online knowledge sharing in an organization.

Abstract
Purpose
The purpose of this paper is to investigate the intergenerational occupational mobility for young women (vis-à-vis their mothers) in India and six of its states from its diverse geographic regions which contribute 39 percent of the Indian population.
Design/methodology/approach
The study uses transition/mobility matrices and multiple mobility measures for examination of intergenerational occupational mobility among young females in India by using the data from the “India Youth Survey: Situation and Needs” from the year 2006 to 2007.
Findings
The study finds that intergenerational occupational mobility among the young women in India is about 71 percent, but surprisingly it is predominantly downwards. The urban areas have higher occupational mobility than the rural areas. However, upward intergenerational occupational mobility is lower among the young SC/ST women compared to the young women belonging to the “Others” caste category. Moreover, upward mobility in the economically and demographically poorer states is much lower than that of other states.
Originality/value
The present study is the only study which examines how women perform vis-à-vis their mothers in terms of occupational attainment in the Indian context.

Abstract
While the world grappled with the COVID-19 pandemic and its externalities, scientists have recommended that the global community brace against potential future pandemics. The need to build resilient systems has never been this urgent. The world, especially emerging economies, faces acute food insecurity, high food prices, failing health infrastructure and rampant misinformation spread, among others. Since blockchain technology (BCT) has been discussed in the supply chain resilience context, and it offers the potential to develop resilient systems, we aim to outline the potential of BCT to help build resilience against ongoing and future pandemics. Mainly, we focus on BCT for healthcare management, disruption management of food supply chains, human resource management, modern education and certification and governance and administration.

This study aims to provide a scientific framework for the selection of suitable substation technology in an electrical power distribution network.
Abstract
Purpose
This study aims to provide a scientific framework for the selection of suitable substation technology in an electrical power distribution network.
Design/methodology/approach
The present paper focuses on adopting an integrated multi-criteria decision-making approach using the Delphi method, analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS). The AHP is used to ascertain the criteria weights, and the TOPSIS is used for choosing the most fitting technology among choices of air-insulated substation, gas-insulated substation (GIS) and hybrid substation, to guarantee educated and supported choice.
Findings
The results reveal that the GIS is the most preferred technology by area experts, considering all the criteria and their relative preferences.
Practical implications
The current research has implications for public and private organizations responsible for the management of electricity in India, particularly the distribution system as the choice of substations is an essential component that has a strong impact on the smooth functioning and performance of the energy distribution in the country. The implementation of the chosen technology not only reduces economic losses but also contributes to the reduction of power outages, minimization of energy losses and improvement of the reliability, security, stability and quality of supply of the electrical networks.
Social implications
The study explores the impact of substation technology installation in terms of its economic and environmental challenges. It emphasizes the need for proper installation checks to avoid long-term environmental hazards. Further, it reports that the economic benefits should not come at the cost of ecological degradation.
Originality/value
The present study is the first to provide a decision support framework for the selection of substation technologies using the hybrid AHP-TOPSIS approach. It also provides a cost–benefit analysis with short-term and long-term horizons. It further pinpoints the environmental issues with the installation of substation technology.

Abstract
This chapter will consider the workings of microcelebrity in the context of an evolving Indian cyber public. In the contemporary moment, large-scale battles for control over the world’s youngest and increasingly digitally active demographic are in full swing – both by corporations like Facebook through efforts like Free Basics, as well as by ideologues who wish to mold the “idea of India” in certain ways. While digital spaces are often framed as liberating, there are also extremely strong conservative forces that are well established. It is within this context that I would like to examine the recent growth of the Indian online comedic scene whose popularity has increased by leaps and bounds. My particular focus will be the comedy collective of AIB (All India Backchod), who are most prominent on Youtube. This collective has garnered significant popularity through their deployment of viral comedic videos riffing off on various aspects of Indian society and have also made socially aware videos around hot button issues like gay rights and women’s rights. I would like to examine their treatment of gender and sexuality particularly in the context of it being made up primarily of straight men and how that has affected their engagement both with the content of their videos, as well as their ability to leverage their online visibility. I will be using ideas of postcolonial cyberspace as theorized by Nishant Shah (2015) as well as theorists of microcelebrity and the use of humor such as Theresa Senft (2013).

Abstract
The purpose of this research study was to examine the role of Social Networking Technologies (SNT) in developing Public Services Supply Chain (PSSC) during COVID-19 pandemic. Due to lack of sufficient support from corporations and non-government groups, citizens in developing democracies were dependent upon their governments for the delivery of vital public services. During the COVID-19 epidemic, a number of organisations attempted to assist governments in managing the supply of public services. However, organisations often lacked a thorough grasp of how to cultivate social ties for the delivery of efficient and effective public services for citizens. In this research work, to study the delivery of efficient and effective public services to citizens, the authors have proposed a social network viewpoint. This was at a ‘meso-level’ lens so as to examine the intersection between organisational SNT and PSSC. According to the qualitative study conducted in this research work, it became evident that organisational social ties could play a significant role in facilitating homophilic and heterophilic ties. This was specially so for the distribution of public services in pandemic situation like COVID-19. However, the research study findings also found out that these network forces were highly dynamic and dependent upon a set of factors. These factors included tie frequency, the sequencing of interaction with social ties and the prevailing norms. This research study enriched the understanding regarding the role of SNT. This was in the context of developing PSSC during critical crisis situations such as prevalent during COVID-19 pandemic. This research study offered a better understanding of social ties and motivational factors in the social networking environment. The social ties were analysed based on the contact incidents of six participants focusing on the PSSC during the COVID-19. Future research studies could consider a diverse set of participants in complex global PSSC consisting of multiple constraints. Furthermore, this research study had practical implications for managers. The study revealed that homophilic social ties were more supportive as compared to the sequence of interactions starting with heterophilic ties. Therefore, managers needed to develop better PSSC especially as compared to unrelated institutions.
