Abstract
The paper explores the relationship of humane orientation of organizations with members' reactions to such treatment by the organization. Orientation of mangers to form good relationships with subordinates has been reflected through subordinatesa’ perception of quality of leader-member exchange (LMX) and it was expected to predict members’ reaction through feeling of exhaustion (burnout). The roles of humane orientation of organizational support measured through perceived organizational support (POS) by subordinates and organizational identification (OID) as possible explicators of the relationship between LMX quality and organizational burnout have also been explored. We conducted three step hierarchical linear regressions on a sample involving data at two time waves. As expected, all the hypotheses were supported. A major contribution of the research to academic literature is the corroboration of directionality of some of the relationship through two time wave design. Also, burnout in this research has been measured at an organizational level and the results were in line with burnout measured at the job level in some earlier studies on burnout.

Abstract
Purpose
The purpose of this study is to investigate the financial well-being and social capital of Indian retirees. The paper investigates the extent of subjective financial well-being, the dependence on debts and the extent of bridging and bonding social capital of retirees with similar retirement pensions to understand the main issues they face.
Design/methodology/approach
Semi-structured interviews were conducted with 32 retired government schoolteachers. Two individuals transcribed the interviews after a pilot study, which helped remove repetitive responses. After ensuring the authenticity of the transcripts, the data was analyzed using interpretive phenomenological analysis.
Findings
The study's key findings reveal that retirees, armed with a clear understanding of their retirement income, exhibit a sense of financial control. At the same time, the presence of debt and the potential for high healthcare expenses adversely impact their subjective financial well-being. In terms of social capital, retirees predominantly rely on support from close-knit communities of friends and neighbors, as against their children. Additionally, retirees who migrate from their native places encounter challenges in establishing bridging social capital.
Originality/value
This study contributes to the ongoing discourse on financial well-being, specifically within the context of vulnerable groups such as retirees in India, where the absence of a state-supported retirement system adds a distinctive dimension. Against the backdrop of India's traditional societal framework, the research extends the existing literature by delving into the nuanced effects of evolving social dynamics on the social capital of retirees.

Abstract
Learning outcomes
After completion of the case study, the students will be able to assess Paytm’s share buyback in the context of conventional practices, especially for loss-making firms, analyze the influence of initial public offering (IPO) performance on market sentiments and the role of subsequent events in shaping investor confidence, explore the regulatory framework for share buybacks in India and its impact on Paytm’s decision, scrutinize Paytm’s post-IPO financials and evaluate the board’s rationale for the share buyback and examine the factors influencing Paytm shareholders’ decisions amid the buyback, considering market conditions and the company’s outlook.
Case overview/synopsis
This case study discusses the unorthodox choice made by Paytm, a leading Indian digital payments and financial services provider, to begin a share repurchase program just one year after its substantial IPO. Paytm encountered difficulties as its stock price experienced a sharp decline of 74% following the IPO, which raised concerns among shareholders and elicited mistrust from analysts. This case study explores the reasoning for the buyback, the legislative framework of share buybacks in India and the diverse viewpoints of analysts regarding the company’s financial strategy. This case study provides not only ample opportunity to discuss ethical issues around managers’ corporate actions but also brings investors a dilemma.
Complexity academic level
This case study is suited to Master of Business Administration/Master of Science/Bachelor of Business Administration/Bachelor of Science.

Abstract
Purpose
Air connectivity network is an important part of the overall connectivity network of any country. This becomes even more crucial for the interior regions, which have no access to sea routes and have inadequate road and rail connectivity. In India there is uniform distribution of airports throughout the country but only a few of them are currently used because of poor infrastructure availability at these airports. Any aircraft operating from these airports, having minimal infrastructure, need to have efficient high‐lift systems for short takeoff and landing ability as one of the key requirements. The purpose of this paper is look at the performance of a new high‐lift airfoil configuration for application to a general transport aircraft.
Design/methodology/approach
The present study deals with two‐dimensional analyses of a high‐lift system for general transport aircraft. The JUMBO2D, a multi‐block structured viscous code has been used to make preliminary analysis of the proposed high‐lift system. The configuration consists of three elements, namely, the main airfoil with nose droop, a vane and a flap.
Findings
In the present work the code has been revalidated by computing for NLF (1) 0416 airfoil (clean) and NACA 1410 airfoil with double‐slotted flap. The computed results compare very well with the experimental data. The proposed high‐lift configuration of general transport aircraft has then been analyzed in detail for both takeoff and landing conditions with and without nose droop. The effect of gap between main element and vane on the aerodynamic performance has also been investigated.
Originality/value
This computational study looks at the performance of a new high‐lift airfoil configuration for application to a general transport aircraft.

Abstract
Purpose
The rapid growth of the gig economy has reshaped the labor market and provided flexible work opportunities but also exposed gig workers to challenges such as job insecurity, anxiety and mental health concerns. For women gig workers, these challenges are often more pronounced due to the precarious nature of gig work and the lack of social protections.
Design/methodology/approach
A cross-sectional survey was conducted with 603 women gig workers across various sectors in India’s major metro cities. The survey used a combination of Likert scale and structured questionnaire to assess anxiety, mental health, job insecurity, workplace challenges and overall well-being, with reliability tests confirming internal consistency.
Findings
Descriptive statistics revealed moderate levels of anxiety, job insecurity and workplace challenges, with most respondents reporting relatively positive perceptions of well-being. Reliability analysis indicated satisfactory internal consistency across the survey constructs, with Cronbach’s alpha values ranging from 0.774 to 0.789. Hypothesis testing showed significant negative correlations between anxiety, job insecurity, workplace challenges and well-being, indicating that higher levels of these stressors are associated with lower well-being. The findings emphasize the need for targeted interventions and policy enhancements to improve the working conditions and support systems for women gig workers.
Research limitations/implications
The study highlights the need for tailored policies and interventions to address the unique challenges faced by women gig workers. Enhancing social protections, providing mental health support and ensuring safer working conditions could help improve their overall well-being.
Originality/value
This study adds to the limited literature on women gig workers in India by examining the specific factors influencing their well-being. It offers new insights into the intersection of gender and gig work, emphasizing the need for policy frameworks that better support this vulnerable workforce.

Abstract
Purpose
The purpose of this paper is to develop knowledge management constructs comprising of KM processes and KM practices through marketing and sales to derive competitive advantage (CA) in the cement industry.
Design/methodology/approach
A thorough and detailed analysis of the literature was carried out to develop the measures for KM practices, KM processes and their impact on CA. A total of 65 variables affecting competitiveness in the form of questionnaire were developed. The questionnaire was administered through e-mail to 962 territory sales managers (TSM) and equivalent employed in the marketing and sales function of the cement organizations in India. A total of 121 valid and complete responses were received, representing a response rate of 12.6 percent. The factor analysis was carried out on the data collected to establish reliability and validity of the measures.
Findings
A total of seven constructs pertaining to knowledge management practices and processes and competitiveness that comprises of 65 variables have been developed. The statistical results establish that the constructs and the variables considered in the study are reliable and valid.
Research limitations/implications
The sample of respondents for developing constructs consisted of TSM and equivalent employed in the marketing and sales function of cement companies in India. Research scope can be enhanced in the future study by including middle and senior level managers in cement companies to better diagnose and understand perception of KM initiatives across different levels in the cement industry. The work can also be extended to incorporate inbound logistics and procurement that directly contributes to the overall value chain to have a holistic perspective.
Practical implications
The measures developed in this study would be effective management tools for the implementation of knowledge management initiatives in the marketing and sales function to ascertain their level of implementation and impact on the competitiveness.
Originality/value
This study is probably the first of its kind in India to provide KM measures combined for practices and processes to understand the relationship with competitiveness in cement companies pertaining to marketing and sales function. It provides valuable insights as a strategic tool for investing in KM initiatives.

Abstract
Purpose
The purpose of this paper is to investigate the effect of high-k material HfO2 as a buffer layer for the fabrication of metal-ferroelectric-insulator-silicon (MFeIS) structures on Si (100) substrate.
Design/methodology/approach
RF-sputtered Pb[Zr0.35Ti0.65]O3 or (PZT) and plasma-enhanced atomic layer deposited HfO2 films were selected as the ferroelectric and high-k buffer layer, respectively, for the fabrication of metal-ferroelectric-insulator-silicon (MFeIS) structures on Si (100) substrate. Multiple angle ellipsometry and X-ray diffraction analysis was carried out to obtain the crystal orientation, refractive index and absorption coefficient parameters of the deposited/annealed films. In the different range of annealing temperature, the refractive index was observed in the range of 2.9 to 2 and 1.86 to 2.64 for the PZT and HfO2 films, respectively
Findings
Electrical and ferroelectric properties of the dielectric and ferroelectric films and their stacks were obtained by fabricating the metal/ferroelectric/silicon (MFeS), metal/ferroelectric/metal, metal/insulator/silicon and MFeIS capacitor structures. A closed hysteresis loop with remnant polarization of 4.6 µC/cm2 and coercive voltage of 2.1 V was observed in the PZT film annealed at 5000 C. Introduction of HfO2 buffer layer (10 nm) improves the memory window from 5.12 V in MFeS to 6.4 V in MFeIS structure with one order reduction in the leakage current density. The same MFeS device was found having excellent fatigue resistance property for greater than 1010 read/write cycles and data retention time more than 3 h.
Originality/value
The MFeIS structure has been fabricated with constant PZT thickness and varied buffer layer (HfO2) thickness. Electrical characteristics shows the improved leakage current and memory window in the MFeIS structures as compared to the MFeS structures. Optimized MFeIS structure with 10-nm buffer layer shows the excellent ferroelectric properties with endurance greater than E10 read/write cycles and data retention time higher than 3 h. The above properties indicate the MFe(100 nm)I(10 nm)S gate stack as a potential candidate for the FeFET-based nonvolatile memory applications.

Abstract
Purpose
AA2014 is a copper-based alloy and is typically used for production of complex machined components, given its better machinability. The purpose of this paper was to study the effects of variation in weight percentage of ceramic Al2O3 particulates during electrical discharge machining (EDM) of stir cast AA2014 composites. Scanning electron microscopy (SEM) examination was carried out to study characteristics of EDMed surface of Al2O3/AA2014 composites.
Design/methodology/approach
The effect of machining parameters on performance measures during sinker EDM of stir cast Al2O3/AA2014 composites was examined by “one factor at a time” (OFAT) method. The stir cast samples were obtained by using three levels of weight percentage of Al2O3 particulates, i.e. 0 Wt.%, 10 Wt.% and 20 Wt.% with density 1.87 g/cc, 2.35 g/cc and 2.98 g/cc respectively. Machining parameters varied were peak current (1-30 amp), discharge voltage (30-100 V), pulse on time (15-300 µs) and pulse off time (15-450 µs) to study their influence on material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR).
Findings
MRR and SR decreased with an increase in weight percentage of ceramic Al2O3 particulates at the expense of TWR. This was attributed to increased microhardness for reinforced stir cast composites. However, microhardness of EDMed samples at fixed values of machining parameters, i.e. 9 amp current, 60 V voltage, 90 µs pulse off time and 90 µs pulse on time reduced by 58.34, 52.25 and 46.85 per cent for stir cast AA2014, 10 Wt.% Al2O3/AA2014 and 20 Wt.% Al2O3/AA2014, respectively. SEM and quantitative energy dispersive spectroscopy (EDS) analysis revealed ceramic Al2O3 particulate thermal spalling in 20 Wt.% Al2O3/AA2014 composite. This was because of increased particulate weight percentage leading to steep temperature gradients in between layers of base material and heat affected zone.
Originality/value
This work was an essential step to assess the machinability for material design of Al2O3 reinforced aluminium metal matrix composites (AMMCs). Experimental investigation on sinker EDM of high weight fraction of particulates in AA2014, i.e. 10 Wt.% Al2O3 and 20 Wt.% Al2O3, has not been reported in archival literature. The AMMCs were EDMed at variable peak currents, voltages, pulse on and pulse off times. The effects of process parameters on MRR, TWR and SR were analysed with comparisons made to show the effect of Al2O3 particulate contents.
