Abstract

Purpose

The purpose of this paper is to investigate the surface integrity features, including surface roughness (SR), recast layer (RL), material migration, topography and wire wear pattern in rough and trim-cut wire electric discharge machine (WEDM) of hybrid composite (Al6061-90%/SiC-2.5%/TiB2-7.5%).

Design/methodology/approach

Effects of four important factors, namely, rough-cut history (RCH), pulse on time (Ton), peak current (IP) and wire offset (WO) have been assessed on the responses of interest for trim-cut WEDM. Box–Behnken design (RSM) was used to formulate the experimentation plan. Quantitative indices of surface integrity, namely, SR and RL, and selected samples have been investigated for qualitative analysis, namely, surface topography, material migration and wire wear pattern.

Findings

Ton and IP are found to be most significant, whereas RCH and WO are found insignificant for SR. Ton and WO were found to be the most significant factors affecting RL. After trim cut, an RL of thickness 8.26 µm is observed if the initial rough cut has been accomplished at high discharge energy setting. Whereas the best value of RL thickness, i.e. 5.36 µm, can be realized with low level of RCH. A significant decrease in the presence of foreign materials is recorded, indicating its strong correlation with the discharge energy used during machining.

Originality/value

Investigation on surface integrity features for machining of hybrid composite through rough and trim-cut WEDM has been reported by only a limited number of researchers in the past. This study is attempted at fulfilling few vital gaps by addressing the issues such as evaluation of the efficacy of trim cutting under different discharge energy conditions (using RCH), analysis of wire wear pattern in both rough and trim-cut modes and investigation of the wire breakage phenomenon during machining.

Abstract

Purpose

This paper aims to examine the relationship between perceived investments in employees’ development (PIED) on work engagement and the moderating effects of psychological capital on this relationship for liquid knowledge workers, employed in the Indian cutting and polishing of diamond industry (CPD).

Design/methodology/approach

A questionnaire composed of established scales was administered to 134 liquid knowledge workers. Having established convergent and discriminant validity using structural equation modelling, the model was further analysed using the Process macro to check for direct and moderating effects.

Findings

The research findings suggest that the perceived investment in employee development and psychological contract enhancement (relational and transactional) made by CPD units for liquid knowledge workers positively influenced their work engagement level. The study also finds that relational contract (not transactional contract) positively moderates the relationship between perceived investment in employee development and work engagement.

Research limitations/implications

This is a cross-sectional single source study; future studies could look at longitudinal and multisource perspective.

Practical implications

The study presents a “star matrix of engagement” that guides the application of the two strategies of perceived employee development and psychological contract enhancement for liquid knowledge workers. This has implications for design and implementation of human resource management practices and policies for employee management.

Originality/value

The study makes significant contributions to existing literature on antecedents of work engagement of liquid knowledge workers by examining the direct and moderating influences.

Abstract

Purpose

This study aims to focuses on the paradox of the great resignation (GR), great layoff (GL) and moonlighting (ML) phenomena triggered by the unprecedented complexity, extreme emotional distress and uncertainty caused by the pandemic to explore ways for mitigating their impact on the intention to stay (ITS).

Design/methodology/approach

A systematic literature review was conducted to explore the impact of the paradoxical GR, layoffs and ML on the ITS by the text analysis of a pool of 111 published articles across 57 journals between 2012 and 2024 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach. The factors impacting the ITS, and the underlying interlinkages of the paradoxical GR, GL and ML phenomena were subsequently inductively deduced using Nvivo software.

Findings

The new theoretical framework explains the evolving dynamics of the ITS and prompts toward a concurrent approach of viewing the paradoxical GR, layoffs and ML through a “common lens” revealing novel insights.

Practical implications

Employees have reprioritized work-life balance, mental health, multiple jobs for varied income streams, flexible work schedules and job satisfaction. Human resource managers should prioritize these aspects and adapt to the evolving workforce dynamics to create a resilient, employee-centric organizational environment where employees choose to stay.

Originality/value

To the best of the authors’ knowledge, this is the first study to concurrently examine the current paradox of the GR, layoffs and ML for enhancing the ITS, necessitating a re-evaluation of traditional perceptions of unemployment and job seeking.

Abstract

Purpose

The purpose of this study is to present a bibliometric and network analysis that uses the Scopus and Dimension databases to provide new insights into the progression toward the study of sustainable economic development.

Design/methodology/approach

This analysis has been drawn on 665 papers published between 2015 and 2023. Bibliometric analysis characterizes a research topic by identifying leading nations, the most significant authors and expressive publications. Network analysis revealed keyword evolution over time, co-citation patterns and study grouping. Content analysis was used to identify major topic in the discipline, with a focus on their interrelationships. Each publication in the data set is briefly described, along with its methodological approach.

Findings

The results of this study show that green finance plays a major role in long-term economic growth, having a significant influence on the preservation of environmental quality, economic efficacy and a more comprehensive economic system. Financial technology also accelerates the transition to a carbon-neutral economy by enhancing the beneficial effects of green finance on aspects of the economic system and environmental conservation.

Research limitations/implications

The investigation is based only on Scopus and Dimensions-indexed journal articles. However, additional studies should incorporate publications from other reputable databases, such as Web of Science, PubMed and Science Direct, for the bibliometric analysis, so that the findings of the model analysis become more reliable and valid with examination of more documents. The visualization of similarity viewer was used for data analysis in the study, there is a scope for using other tools such as Biblioshiney and CitNet Explorer.

Practical implications

To support long-term economic growth, authorities should encourage Fintech companies to actively participate in various green finance initiatives and environmental conservation businesses. Financial managers should facilitate the integration of technology and green finance for financial services. It is important to encourage institutional and individual investors alike to look into more environmentally friendly ways to invest and save money. Policymakers should provide a platform for global awareness and government agencies should enhance their recommendations to state governments to increase the efficacy of green finance.

Originality/value

This study contributes to the literature by investigating the relationship between Fintech and green financing. This study holds significance for financial intermediaries, industrialists, investors and policymakers by providing insights into the integration of Fintech with green finance for sustainable development. These findings affirm the pivotal role of Fintech and green finance in fostering sustainable economic development. The novelty of the topic and the variety of publications in which it has been published demonstrate that sustainable economic development has piqued the interest of a wide range of areas.

Abstract

Purpose

The main aim of this paper is to explore the influence mechanisms of perceived organizational politics (POP) on employee performance (EP). Drawing on the job demands-resources theory (JD-R), this paper investigates opportunistic silence (OS) as a mediating factor and job level as a moderating effect in the POP-OS-performance relationship.

Design/methodology/approach

This study’s data were collected from 203 employees working in Indian high-power distance organizations (HPDOs), such as the military, police and security forces. Mediation and moderation analysis were conducted using PLS-SEM, and the moderated mediation index was calculated using Hayes PROCESS Macro.

Findings

The results indicate that OS fully mediates the POP-performance relationship – specifically, POP as a job demand activates OS, which acts as an energy/resource depleting mechanism and further deteriorates task performance. Interestingly, the overall negative influence of POP and OS on EP was stronger for employees at lower job levels than those at senior job levels.

Originality/value

This paper offers a unique set of findings that enrich the understanding of factors responsible for employees’ performance in the highly political environments of HPDOs. By using the lens of JD-R theory, this paper draws attention towards the tendency of employees to indulge in self-serving behaviours like OS in politically charged contexts which is detrimental to their performance and may also undermine overall organization’s productivity. Furthermore, this paper also highlights the conditional effects exerted by job level in the unique nexus of POP, OS and EP.

Abstract

Purpose

Knowledge is considered as a strategic asset for the organizations, especially for knowledge-intensive firms. Research and development (R&D) is a significant unit in organizations, as it is devoted to knowledge creation and transfer. The success of any R&D project in an organization depends on its innovative value and the transfer of knowledge to the employees. This study aims to focus on factors triggering knowledge-hiding behavior among R&D employees, thus disrupting the knowledge creation in the organization.

Design/methodology/approach

The grounded theory approach has been used to analyze qualitative data collected from 19 in-depth interviews of R&D professionals (middle and junior level) working in Indian pharmaceutical firms.

Findings

The study identified factors that triggered knowledge-hiding behavior among employees. These factors include distrust, competitive work environment, perceived career insecurity, lack of recognition, lack of reciprocation and lack of confidence in own knowledge. In addition, four hiding strategies used by employees to hide their knowledge from their fellow members were explored and identified: playing innocent, being misleader/evasive hiding, rationalized hiding and counter-questioning.

Research limitations/implications

Besides improving the understanding of knowledge-hiding behavior, particularly in the Indian context, this study has implications for both managerial practices and organizational policies.

Originality/value

This paper highlights the factors influencing knowledge-hiding behavior among R&D employees. Knowledge-hiding construct has not been adequately studied; however, it prevails in the organization and has potential to influence various individual- and organizational-level outcomes. In addition, ways of hiding knowledge used by employees were identified and new forms of strategies named “counter-questioning” were found.

Abstract

Purpose

The purpose of this paper is to analyze the surface integrity, including recast layer thickness, surface crack density, X-ray diffractions study and microhardness for Ni53.49Ti46.51 shape memory alloy (SMA) during wire-spark erosion machining.

Design/methodology/approach

Four persuasive process parameters, that is, spark on time (SON), spark off time (SOFF), wire feed (WF) and spark gap voltage (SV), have been chosen for the current investigation. Efforts have been done to explore the effects of above said parameters on the machined surface of Ni-Ti SMA by embracing box Behnken design of response surface methodology (RSM). Cutting speed and ten-point mean roughness (Rz) has been taken into account as response variables. Analysis of variance test was also performed for both response parameters with the coefficient of determination (R2) 0.9610 for cutting speed and 0.9252 for ten-point mean Rz.

Findings

The recast layer thickness from 7.83 to 12.13 µm was developed near the machined surface at different parametric settings. The least surface crack density was found at the lowest value of ten-point mean Rz, while most surface crack density was identified at the highest value of cutting speed. The microhardness near the machined surface was increased by approximately 1.8 times bulk-hardness of Ni53.49Ti46.51 SMA.

Originality/value

Some researchers have done a study on average surface roughness, but very few investigators concentrated on ten-point mean Rz. Surface crack density is an essential aspect of machined parts; other researchers have seldom reported it. The novelty of this research work is that the influence of SON, SV, WF and SOFF on cutting speed, Rz, recast layer thickness, micro-hardness and surface crack density proximate the machined surface while machining workpiece material.

Abstract

Purpose

Does the simultaneous vertical and horizontal alignment of HR systems positively impact innovation? The authors use the “innovation value chain” model to explore the interplay between the central strategic human resource management concepts of vertical and horizontal fit of HR systems and their role in positively impacting product innovation management.

Design/methodology/approach

The authors use the findings from a case study of a large multinational organization in the high-tech sector for the present study. In the first phase, the authors analyse responses to 20 qualitative interviews with senior business and HR executives at the organization using the grounded theory approach. In the second phase, the authors analysed six years of performance ratings and salary data for 4,500–5,500 employees.

Findings

Phase 1 of the study established the importance of innovation management as a strategic priority and the role of vertical and horizontal fit of HR systems and practices in positively impacting innovation management. Phase 2 reinforced the findings from Phase 1 by demonstrating the vertical and horizontal fit of the performance and compensation management processes towards furthering innovation management. Our study findings suggest that both forms of fit boost innovation management and interact to reinforce each other mutually, magnifying their respective positive effects towards improving innovation management.

Originality/value

While past studies have generally focused on the isolated role of either the HR system or that of a bundle of HR practices on innovation, the present study empirically demonstrates the simultaneous role of vertical and horizontal fit of HR systems and practices in furthering innovation management. The authors use interviews with senior executives and objective performance and salary data to provide the first experimental evidence of the mechanism of the interplay between the two forms of fit.

Abstract

Purpose

The motivation for this study is to understand the stressful situations leading to great resignation and evaluate the cognitions of psychological attachment (PA) and organizational attractiveness (OA) to mitigate this crisis, using the attachment theory as the theoretical basis.

Design/methodology/approach

A cross-sectional study was conducted on individuals employed in Indian organizations (Nifty 50) to identify the most impactful cognitions underlying the dynamics between person–job fit (P-J fit) and the intention to stay (ITS).

Findings

This study highlighted that a serial mediation relationship between PA (specifically “internalization”) and OA is influenced by the P-J “needs–supplies” fit, particularly during extraordinarily stressful times. Managers must re-emphasize PA and OA as core organizational resources that must be prioritized, maintained and refined to reinforce employees' intent to stay in their organizations.

Originality/value

No research has studied P-J fit, PA, OA, underpinned by the attachment theory to reinforce the ITS given the context of the great resignation triggered by the pandemic's extraordinarily stressful situation.

Abstract

Purpose

This paper aims to understand whether the relationship between psychological empowerment, psychological well-being and higher person–job fit based on the self-determination theory could have mitigated the Great Resignation crisis.

Design/methodology/approach

A cross-sectional study was conducted by collecting data from 351 respondents working in Indian organizations (Nifty, 2020) using a standardized questionnaire by using the multifaceted psychological construct within the work context.

Findings

This study highlights that a moderated mediation relationship between psychological empowerment (specifically “impact” or “choice”) and psychological well-being (specifically “environmental mastery”) is impacted by the person–job “demand-abilities” fit and enhances the intention to stay in the current “great resignation” context.

Practical implications

The authors map the theoretical and empirical research of the “intention to stay” by developing the “demand-abilities” fit, which leads to higher levels of psychological empowerment and psychological well-being to build adaptability through effective learning practices.

Originality/value

The authors establish the underlying linkages and future research agenda to strengthen the “intention to stay” during the extraordinarily stressful context of the covid-19 pandemic.
