Abstract

Purpose

This study aims to analyze the dynamic performance of aerostatic thrust bearing for different geometries of recess. Different geometries of recess of equal recess area, i.e. circular, elliptical, rectangular and annular, have been considered in analysis. The work also analyzes the influence of tilt angle on the performance of thrust bearing. To compute the unknown pressure field, the Reynolds equation governing the flow of compressible lubricant (air) has been solved using finite element formulation. Further, separate finite element formulations have been carried out to compute fluid film stiffness and damping coefficients directly. This method provides quick computation of stiffness and damping coefficients of aerostatic thrust bearing than the usual approach.

Design/methodology/approach

As the Reynolds equation governing the flow of compressible lubricant is nonlinear partial differential equation, the computation of the stiffness and damping coefficient follows an iterative procedure. It requires a lot of computational energy. Therefore, in the present work, a novel technique based on finite element formulation is suggested to compute air film stiffness and damping coefficient in aerostatic thrust bearing.

Findings

A novel technique based on finite element formulation is illustrated to simulate the performance of tilted pad aerostatic thrust bearing. On the basis of simulated results, following key conclusions may be drawn. The static and dynamic performance of a circular aerostatic tilted thrust pad bearing is significantly affected with a change in the value of tilt parameter and the shape of the recess.

Research limitations/implications

Implications are as follows: direct computation of air film damping coefficient is performed without perturbation method in finite element method (FEM); influence of tilt on aerostatic thrust bearing is studied; influence of recess shape on aerostatic thrust bearing is observed; and finite element formulation of aerostatic thrust bearing is performed.

Originality/value

The present work will be quite useful for bearing designer and academicians.

Abstract

Purpose

The purpose of this study is to identify how the privacy policy can be framed for protection of personal data and how the latest judgement of full bench of Supreme Court of India has dealt with right to privacy in India.

Design/methodology/approach

The study uses the latest Supreme Court judgement on right to privacy and historical cases on right to privacy in India. This paper uses Indian Constitution as a source of Information for study along with case laws and judgements of different courts in India.

Findings

This paper tries to find if personal data privacy is a fundamental right in India. In addition, the paper provides recommendations to different concerned authorities on protecting personal information in online platform.

Research limitations/implications

This study deals with privacy issues so far as Indian citizens are concerns and does not focus on other countries. Moreover, the study tries to understand the issue of fundamental rights from Indian Constitution perspective. In addition, the recommendations provided to the policymakers and other authorities of India have wide implications for formulation of new policy and management of personal data, so that it should not go to wrong hands and the personal data and privacy is protected of the citizens.

Practical implications

Millions of people put their personal information in online platform. In addition, there are few government initiatives in India such as Aadhaar card where the biometric information is taken from the residents of India, and in many cases, the personal data are compromised under various circumstances. As the personal data of the citizens are in question, thus the study has direct practical implication mainly for all the citizens whose personal data are available in online platform.

Social implications

This study has social implication as it dealt with the “personal data” of the citizens of India. As the paper discusses the issue of protection of personal data in the context of right to privacy, thus this study has a direct social impact so far as online citizen of India is concerned.

Originality/value

This paper is timely, original and discusses the contemporary issue of online data privacy and fundamental right in India. This paper is a useful resource for the researchers, policymakers and online users who deal with personal data-, right to privacy and data privacy policy-related areas.

Abstract

Purpose

The aim of the present paper is to study the combined influence of textured surface and micropolar lubricant behaviour on the performance of two-lobe hole-entry hybrid journal bearing system. The bearing performance parameters of the textured circular/two-lobe hole-entry hybrid journal bearing system have been computed against the constant vertical external load supported by the bearing.

Design/methodology/approach

In this work, Eringen’s micropolar fluid theory has been used to derive the governing Reynolds equation. The consequent solution of the governing Reynolds equation has been obtained by using finite element method (FEM) numerical technique.

Findings

The present study indicates that the use of the textured surface, two-lobe profile of bearing and micropolar lubricant, significantly enhances the bearing performance as compared to non-textured circular journal bearing.

Originality/value

The present study concerning the influence of surface texturing on the behaviour of the two-lobe hole-entry hybrid journal bearing lubricated with micropolar lubricant is original. The theoretically simulated results of the present study will be useful to design an efficient journal bearing system.

Abstract

Purpose

This study aims to assess the factors influencing the effective implementation of extended producer responsibility (EPR) practices within the context of sustainable accounting goals and circular economy principles. It seeks to provide insights into the significance of EPR policies for manufacturing industries striving to enhance their environmental, social and governance performance while ensuring sustainable accounting of their business operations.

Design/methodology/approach

The methodology proposed in this article is based on the decision-making trial and evaluation laboratory (DEMATEL) technique. This approach formulates a structural framework for evaluating influential elements among critical recognized factors. By using DEMATEL, the study examines the interconnectedness between assessed factors through a cause-and-effect diagram, facilitating the integration of EPR into sustainable accounting practices.

Findings

The research findings reveal that the most impactful contributors to sustainable accounting practices of EPR within the framework of sustainable development goals and circular economy are producers, consumers, eco-design, public awareness and the support of local authorities. These findings underscore the importance of considering these factors in implementing EPR and advancing sustainable accounting practices.

Originality/value

This paper contributes to the literature by proposing a DEMATEL-based model for evaluating the factors affecting the implementation of EPR within the context of sustainable accounting goals and circular economy principles.

Abstract

Purpose

This study aims to revisit the properties of 24-item version of mindfulness scale proposed by Bohlmeijer et al. (2011) in an Indian context to add to the existing global knowledge base on mindfulness.

Design/methodology/approach

A questionnaire was administered to 531 adult employees working in the IT/ITES sector in India. Their responses were analysed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and validity statistics to validate the Indian adaptation of the five-facet mindfulness questionnaire (FFMQ).

Findings

The findings confirmed that the Indian version of the 24-item short form of the FFMQ (denoted as FFMQ-SF) matches the findings of Bohlmeijer et al. (2011). It can, therefore, provide valuable insights to both employees and management on the benefits of mindfulness in the workplace.

Research limitations/implications

This paper also presents the limitations of this work along with scholarly and practical implications. It enhances the global understanding of mindfulness, with applications in education, health and well-being, workplaces, social justice, spirituality and personal growth.

Originality/value

This study justifies and presents a unique instrument for assessing employee mindfulness and is beneficial for both management and employees in navigating the evolving hybrid work environment. It promotes present-moment awareness in a non-judgemental manner, facilitating perspective shifts, improved self-regulation and experiential acceptance. Additionally, the study affirms the five-dimensional structure underlying the mindfulness construct.

Abstract

Purpose

This study aims to explore the impact of the containment measures during COVID-19 on individuals’ finances, financial resilience during such distress and identifying the most financially vulnerable among them. Tracing such impact during the pandemic has been challenging due to a lack of representative data. This paper addresses this gap in the present study.

Design/methodology/approach

A survey has been conducted using a structured questionnaire containing various items that portray the impact on income, spending, saving, investment, borrowing, insurance and retirement. The sample consists of 699 respondents and purposive and snowball sampling has been used for data collection. The results are presented and analyzed using infographics and frequency distributions. This study conducts an analysis of variance and Chi-square tests for significance.

Findings

This paper finds a fall in income and limited ability to cope with the current economic conditions. The survey highlights inadequate savings and insurance, weak retirement planning, outstanding loans and under-diversified investments inhibiting financial resilience even among the higher-income group. Particularly, lower-income strata, women and not much educated are most financially vulnerable. Further, no substantial financial benefits have been received from the government and people rely on their usual income sources.

Originality/value

To the best of the authors’ knowledge, this is the first study that measures the pandemic’s impact on personal finances, especially in connection with a developing economy like India. Policy interventions are critical to the millions for whom financial literacy is required now more than ever.

Abstract

Purpose

The purpose of the study is to examine the value-based performance of firms in construction sector in India using Tobin's Q and Market Capitalization (MCAP) and then determine their significant financial drivers.

Design/methodology/approach

The study is based on data from 87 firms engaged in infrastructure, real estate, industrial construction and allied areas in India over a study period of 10 years. Three distinct forms of panel regression models have been developed using Tobin's Q and MCAP as dependent variables. The models developed are using Baltagi's (1981) Error Component 2SLS, Varadharajan-Krishnakumar's (1987) Generalized 2SLS and Arellano – Bower/Blundell – Bond's (1991) dynamic panel.

Findings

The study found that MCAP is a better suited value-based performance measure for construction sector firms in India. The study further reports that the age of the firm, profit after tax, investment in research and development, dividends, leverage and net fixed asset are significant positive drivers, whereas cash flow is a significant negative driver.

Research limitations/implications

The study is limited to a geographic location; therefore, the findings of this study cannot be generalized.

Practical implications

As MCAP is a better suited value-based performance measure of a firm in the construction sector, managers should focus on improving profitability, higher research and development activities, higher dividends and higher expenditures on net fixed assets for improvement.

Originality/value

This is an original attempt to examine the value-based performance of firms in the construction sector in India using Tobin's Q and MCAP.

Abstract

Purpose

The purpose of this paper is to analyze the effects of various factors like profitability, growth opportunity, financial leverage, assets tangibility, operating cash flows, age and size of firm on working capital requirements (WCR) of manufacturing SMEs in India.

Design/methodology/approach

The paper uses a panel data regression model with fixed and random effect estimations. The data utilized in this study includes financial data of 254 manufacturing SMEs operating in India for the period 2010 to 2014.

Findings

The overall results of the study indicate that operating cash flow, financial leverage, profitability, sales growth and asset tangibility are the key drivers of WCR for Indian manufacturing SMEs. Profitability of firm and sales growth are found to be positively related to WCR. In contrast, asset tangibility, operating cash flow and financial leverage are found to be negatively related to WCR.

Research limitations/implications

This paper investigates firm-specific factors while ignoring external factors like GDP growth, business indicators and industry type. Further research can be done to assess the effect of these external factors on WCR.

Originality/value

This research contributes to the working capital literature by providing empirical evidence on determining factors of WCR in manufacturing SMEs.

Abstract

Purpose

This study aims to embark on a bibliometric journey through the International Journal of Retail & Distribution Management (IJR&DM) to delve into its rich repository of applied retailing research.

Design/methodology/approach

626 publications in IJR&DM between 2015 and 2023 have been retrieved from Scopus for performance analysis of the journal’s publication (productivity) and citation (impact) trends as well as a science mapping of the journal’s collaborators (contributors) and major themes (contributions).

Findings

The performance analysis highlights the growth in the productivity and impact of IJR&DM alongside its most cited publications, most prolific contributors, most relied-on journals, as well as the authors, institutions, countries, and journals that the journal has impacted the most. The co-authorship analysis reveals the collaboration (i.e., international with a high concentration in Europe and North America along with an emerging presence in Asia) of IJR&DM. Keyword co-occurrence analysis and bibliographic coupling reveal eight themes. Our exploration revealed close interconnections among various domains including retailing and adaptive strategies, channel strategies, customer experience, market innovations, operations management, relationship marketing, shopping motivation, and sustainability.

Research limitations/implications

Although this study delivers a state-of-the-art overview of the retail industry through the scientific contributions from IJR&DM, it remains limited to the insights from a single authoritative source of knowledge on retailing.

Originality/value

No review, to date, has been conducted for IJR&DM. This study provides the inaugural retrospective of the scientific contributions of IJR&DM, outlining publication and citation trends alongside the intellectual structure of its body of knowledge on retailing. Theoretically, this retrospective is pivotal in charting the intellectual growth and thematic nuances inherent in retail research. Practically, this study serves as a guide for practitioners, enabling them to make strategically informed decisions and craft forward-looking strategies in sync with current realities.

Abstract

Purpose

The purpose of this paper is to explore the use of chiral single‐walled carbon nanotubes (SWCNTs) as mass sensors. Analysis of SWCNT with chiralities is performed using an atomistic finite element model based on a molecular structural mechanics approach.

Design/methodology/approach

The cantilever carbon nanotube (CNT) is modeled by considering it as a space frame structure similar to three‐dimensional beams and point masses. The elastic properties of the beam element are calculated by considering mechanical characteristics of covalent bonds between the carbon atoms in the hexagonal lattice. The mass of each beam element is assumed as point mass at nodes coinciding with carbon atoms. An atomistic simulation approach is used to find the natural frequencies and to study the effects of defect like atomic vacancies in CNTs on the resonant frequency. The migration of the atomic vacancies along the length is observed for different chiralities.

Findings

A reduction in the simulated natural frequency is observed with the maximum value occurring, when the vacancy is found nearer to the fixed end. It is quite evident from the simulation results that the effect of vacancies is significant, and the effect diminishes at 10−2 femtograms mass. Using the higher modes of vibration of SWCNT‐based mass sensors, the amount and the position of the mass on the nanotube can be identified.

Originality/value

CNT have been used as mass sensors extensively. The present approach is focused to explore the use of chiral SWCNT as sensing device with vacancy defect in it. The variation of the atomic vacancies in CNT along the length has been taken and is analyzed for different chiralities. The effects of defect like atomic vacancies in CNTs on the resonant frequency have been analyzed and observed that the maximum reduction in natural frequency occurs when the vacancy is found nearer to the fixed end due to large stiffness variation.
