Abstract

Purpose

Microcapsule-embedded autonomic healing materials have the ability to repair microcracks when they come into contact with the crack by releasing the healing agent. The microcapsules with specific shape and thickness effect in releasing healing agent to the cracked surfaces. Thus, the purpose of this paper is to know the load bearing capacity of the self-healing microcapsules and the stresses developed in the material.

Design/methodology/approach

In the present study, self-healing microcapsule is modelled and integrated with the polymer matrix composite. The aim of the present study is to investigate failure criteria of Poly (methyl methacrylate) microcapsules by varying the shell thickness, capsule diameter and loading conditions. The strength of the capsule is evaluated by keeping the shell thickness as constant and varying the capsule diameter. Uniformly distributed pressure loads were applied on the capsule-reinforced polymer matrix composite to assess the failure strength of capsules and composite.

Findings

It is observed from the results that the load required to break the capsules is increasing with the increase in capsule diameter. The failure strength of microcapsule with 100 µm diameter and 5 µm thickness is observed as 255 MPa. For an applied load range of 40–160 N/mm2 on the capsules embedded composite, the maximum stress developed in the capsules is observed as 308 MPa.

Originality/value

Failure strengths of microcapsules and stresses developed in the microcapsule-reinforced polymer composites were evaluated.

Abstract

Purpose

In an internal combustion engine, piston ring-cylinder liner tribo pair is one among the most critical rubbing pairs. Most of the energy produced by an internal combustion engine is dissipated as frictional losses of which major portion is contributed by the piston ring-cylinder liner tribo pair. Hence, proper design of tribological parameters of piston ring-cylinder liner pair is essential and can effectively reduce the friction and wear, thereby improving the tribological performance of the engine. This paper aims to use surface texturing, an effective and feasible method, to improve the tribological performance of piston ring-cylinder liner tribo pair.

Design/methodology/approach

In this paper, influence of positive texturing (protruding) on friction reduction and wear resistance of piston ring surfaces was studied. The square-shaped positive textures were fabricated on piston ring surface by chemical etching method, and the experiments were conducted with textured piston ring surfaces against un-textured cylinder liner surface on pin-on-disc apparatus by continuous supply of lubricant at the inlet of contact zone. The parameters varied in this study are area density and normal load at a constant sliding speed. A comparison was made between the tribological properties of textured and un-textured piston ring surfaces.

Findings

From the experimental results, the tribological performance of the textured piston ring-cylinder liner tribo pair was significantly improved over a un-textured tribo pair. A maximum friction reduction of 67.6 per cent and wear resistance of 81.6 per cent were observed with textured ring surfaces as compared to un-textured ring surfaces.

Originality/value

This experimental study is helpful for better understanding of the potency of positive texturing on friction reduction and wear resistance of piston ring-cylinder liner tribo pair under lubricated sliding conditions.

Abstract

Purpose

The current body of empirical research regarding the impact of trust in the cybersecurity commitment of institutions on digital payment usage has focused solely on a macro-level analysis, overlooking the intricate dynamics between institutions' cybersecurity commitments and the trust levels of digital payment users. In light of this limitation, this study aims to offer a more comprehensive understanding of this complex relationship.

Design/methodology/approach

A case study was conducted on digital payment users in India through the critical realist lens. To gather data, interviews and focus group discussions were conducted with digital payment users from various regions of the country.

Findings

The citizen-centric outcomes of the national cybersecurity commitment (performance and responsiveness) are the most prominent and impactful trust indicators. These outcomes play a crucial role in shaping digital payment users' perception and trust in the cybersecurity commitment of public institutions. Individuals' value positions also influence trust judgments, as it is essential to recognize the value tensions that may arise due to security implementation and their congruence with citizens' values.

Research limitations/implications

The findings of this study have significant implications for policymakers. They are potentially an artifact of the security and perception of digital payment users and the cultural uniqueness of digital payment users in India.

Originality/value

The study proposes a holistic understanding of the relationship between institutions' cybersecurity commitments and the trust levels of digital payment users. It offers a qualitative evaluation of how digital payment users perceive and construe efficient information security management implemented by public institutions.

Abstract

Purpose

The study aims to examine the impact of six events related to the escalating Indo-China border conflicts in 2020 on the Indian stock market, including the role of firm-specific variables.

Design/methodology/approach

This study employs an event-study method on a sample of 481 firms from August 23, 2019 to March 3, 2022. A cross-sectional regression is employed to examine the association between event-led abnormal returns and firm characteristics.

Findings

The results show that, although the individual events reflect heterogeneous effects on stock market returns, the average impact of the event categories is negative. The study also found that net working capital, current ratio, financial leverage and operating cash flows are significant financial performance indicators and drive cumulative abnormal returns. Further, size anomaly is absent, indicating that more prominent firms are resilient to new information.

Research limitations/implications

The ongoing conflict between Russia and Ukraine is an example of how these disagreements can devolve into a disaster for the parties to the war. Although wars have an impact on markets at the global level, the impacts of border disputes are local. Border disputes are ongoing, and the study's findings can be used to empower investors to make risk-averting decisions that make their portfolios resilient to such events.

Originality/value

This study provides firm-level insight into the impacts of border conflicts on stock markets. The authors compare the magnitude of such impacts on two types of events, namely injuries and casualties due to country-specific border tensions and a government ban on Chinese apps. Key implications for policymakers, stakeholders and academics are presented.

Abstract

Purpose

The purpose of this research is to analyze the reciprocal relation between total quality management (TQM) and innovation (product innovation and process innovation) and their impact on operational and financial performance.

Design/methodology/approach

The data were obtained from a survey of 205 manufacturing companies. Structural equation modeling (SEM) was performed to evaluate the research model.

Findings

The results reveal that there is a reciprocal relationship between TQM and innovation. Moreover, the findings indicate a significant positive effect of product innovation and process innovation on operational performance and insignificant direct impact of TQM on operational performance. However, this effect is significant when it is mediated through product innovation and process innovation.

Research limitations/implications

This paper helps practitioners to understand how TQM practices support both product and process innovation and the role of the latter in promoting the implementation of TQM practices and ensuring operational performance.

Originality/value

This study presents an innovative approach since it is among the first research studies that provide empirical evidence to a reciprocal association between TQM and innovation. Additionally, this paper examines the dimensions studied in different aspects. It considered financial performance and operational performance, and with respect to innovation, this dimension was analyzed through two different perspectives, namely product innovation and process innovation. This study is also among the first and few research studies that have studied the mediating effect of innovation.

Abstract

Surveys 200 Malaysian students at a US midwestern university to investigate attitudes towards corporate social responsibility. Refers to previous studies exploring the link between corporate social responsibility and financial performance but asserts that there is little empirical evidence on corporate social responsibility and employee attitudes – hence this study. Describes how the survey was carried out (a questionnaire measured on a four‐point Likert scale). Uses t‐tests to evaluate the data. Aims particularly to establish whether or not individuals who value corporate social responsibility exhibit less tolerance of 17 identified counter productive behaviours (such as using organizational services for personal use, padding expense accounts and pilfering organizational supplies). Finds support for the notion that individuals who value corporate social responsibility rate the 17 behaviours as more unethical than individuals who do not especially value corporate social responsibility. Indicates, therefore, that these (more ethical) individuals are less likely to indulge in counter productive behaviour. Recommends ways to back up and extend this research.

Abstract

Purpose

This article aims to examine the direct and indirect effect among total quality management (TQM), corporate social responsibility (CSR) and financial and non-financial performance.

Design/methodology/approach

The empirical data were collected from a survey of 120 Tunisian certified firms using questionnaires. Structural equation path modeling PLS-SEM) was performed to test the research hypotheses.

Findings

The results indicate that TQM has no direct effect on financial performance (FP), while they positively impact non-financial performance (NFP) and CSR. The study also shows that CSR positively and significantly influences FP and NFP. In addition, it reveals the positive impact of FP on NFP. Furthermore, the results reveal an indirect effect of TQM on financial and non-financial performance through CSR.

Originality/value

The empirical study bridges the gap in the literature by analyzing the direct and indirect effect between TQM, CSR and performance in a single model. It also highlights the important role of CSR between TQM and financial and non-financial performance in the context of emerging countries.

Abstract

Purpose

In mobile banking (m-banking), understanding the factors contributing to customer satisfaction is crucial for bank managers to design effective strategies for enhancing the uptake of mobile banking services. This study assesses the relationships between quality, technology acceptance and credibility factors and behavioural outcomes (actual use, continuance intention and loyalty) and satisfaction with m-banking. It further investigates the moderating influence of economy type, innovation level, connectivity level and sample size on all these relationships.

Design/methodology/approach

The study employs a meta-analysis technique and reviews 54 published studies to investigate the antecedents and consequences of satisfaction with m-banking.

Findings

The study finds a significant relationship between satisfaction with m-banking and quality, technology acceptance and credibility factors and behavioural outcomes. It concludes that the moderating effect of economy type, innovation level, connectivity level and sample size partially moderate the majority of the hypothesized relationships.

Research limitations/implications

Drawing on a comprehensive literature review, this study presents a novel framework elucidating the antecedents and behavioural outcomes of satisfaction with mobile banking. It contributes to the literature by exploring the moderating effects of sample size and country context on the relationships between these factors, presenting important implications for future mobile banking research.

Practical implications

This study has practical implications for m-banking service providers, offering insights into the factors that drive user satisfaction with mobile banking and highlighting the need for tailored strategies in different country contexts.

Originality/value

This study examines the effects of factors leading to satisfaction and the subsequent outcomes within the context of m-banking. The findings offer fresh perspectives that can be valuable for managers and policymakers, enabling them to enhance customer satisfaction in the realm of m-banking.
