Abstract

Purpose

This SWOT (strengths, weaknesses, opportunities and threats) analysis was conducted to have a portrait of the competitiveness of Council of Scientific and Industrial Research (CSIR) on the global map. Being a 75-year-old scientific organization, CSIR has raised each and every laboratory with a specific mandate and competency. It is definite that the organization would get some assistance from these points, which are briefly stated, as the institutional data reside with the laboratory only. To some extent, they can be considered on their discretion; however, the organization has raised its position to international standards, but still it can consider few areas/suggestions from this analysis. These points are suggestive and flexible in nature, which are identified and defined to elevate this organization on the globe. Scientific publications do make a difference, but on the ground, if the technologies are not viable and received by public, it makes no difference. Today, India is fortunate to have a Prime Minister like Mr Modi, who always re-evaluates the issues and solutions so that the country moves from developing to a fast-pace developed nation. It is a fact that if these research organizations reorganize themselves and prioritize the research problems, they are capable enough to become a pioneer among the world R&D industry. This paper aims to analyze the organization and suggest few points with significant findings which can assist in scaling toward excellence on a global scale.

Design/methodology/approach

On the basis of random sampling, laboratories were identified where their achievements and contribution toward industry and society were evaluated. On the basis of their setup, the organization and laboratories were evaluated to frame-out a SWOT analysis.

Findings

SWOT analysis is a deliberate technique carried out to analyze the current situation of the system and to analyze the internal and external environment, which provides and edge to the organization to sustain. The major factors assessed were manpower, machines, money and funding, and achievements and deliverables were studied.

Originality/value

The research, i.e. SWOT, is unique in nature, as it was not carried out earlier on such a scale. To some extent, the points suggested in SWOT and conclusion can be considered on their discretion; however, the organization has raised its position to international standards, but still it can consider few areas/suggestions from this analysis. These points are suggestive and flexible in nature, which are identified and defined to elevate this organization on the globe. Scientific publications do make a difference, but on the ground; if the technologies are not viable and received by public, it makes no difference. Today, India is fortunate to have a Prime Minister like Mr Modi, who always re-evaluates the issues and solutions so that the country moves from developing to a fast-pace developed nation. It is a fact that if these research organizations reorganize themselves and prioritize the research problems, they are capable enough to become a pioneer among the world R&D industry.

Abstract

Purpose

The purpose of this paper is to study numerically the influence of a magnetic field on the transient free convective boundary layer flow of a nanofluid over a moving semi-infinite vertical cylinder with heat transfer

Design/methodology/approach

The problem is governed by the coupled non-linear partial differential equations with appropriate boundary conditions. The fluid is a water-based nanofluid containing nanoparticles of copper. The Brinkman model for dynamic viscosity and Maxwell–Garnett model for thermal conductivity are used. The governing boundary layer equations are written according to The Tiwari–Das nanofluid model. A robust, well-tested, implicit finite difference method of Crank–Nicolson type, which is unconditionally stable and convergent, is used to find the numerical solutions of the problem. The velocity and temperature profiles are studied for significant physical parameters such as the magnetic parameter, nanoparticles volume fraction and the thermal Grashof number Gr. The local skin-friction coefficient and the Nusselt number are also analysed and presented graphically.

Findings

The present computations have shown that an increase in the values of either magnetic parameter M or nanoparticle volume fraction decreases the local skin-friction coefficient, whereas the opposite effect is observed for thermal Grashof number Gr. The local Nusselt number increases with a rise in Gr and ϕ values. But an increase in M reduces the local Nusselt number.

Originality/value

This paper is relatively original and presents numerical investigation of transient two-dimensional laminar boundary layer free convective flow of a nanofluid over a moving semi-infinite vertical cylinder in the presence of an applied magnetic field. The present study is of immediate application to all those processes which are highly affected by heat enhancement concept and a magnetic field. Further the present study is relevant to nanofluid materials processing, chemical engineering coating operations exploiting nanomaterials and others.

Abstract

Purpose

This paper aims to examine the weak form of efficiency for price series of four precious metals, i.e. gold, silver, platinum and palladium, using a generalized spectral method.

Design/methodology/approach

The method has the advantage of detecting both linear and non-linear serial dependence in the conditional mean, and it is robust to various forms of conditional heteroscedasticity. The authors use three different rolling windows for the purpose of robustness.

Findings

The authors report weak form of efficiency across metals series for almost all rolling windows. The optimum efficiency for Gold and Palladium is achieved through 250 days rolling window estimates whereas it is 500 days rolling window for silver. Platinum has similar efficiency levels across rolling windows. The degree of efficiency for metal prices is observed to be varying over time with silver market possessing highest levels of efficiency. The efficiency synchronization also varies across rolling windows and metals.

Research limitations/implications

The results reveal that metal markets are efficient for most times implying the low predictability and the low likelihood of earning abnormal returns by speculating in these markets.

Originality/value

The study uses a relatively new statistical technique, the generalized spectral test, to capture linear and non-linear serial dependence. Therefore, the results possess adequate power against departure from market efficiency.

Abstract

Purpose

The digital disruptions have provided alternative methods of monetary transactions. Despite the digital wave, cash as a payment option has regained its position. The purpose of this research is to investigate behavioral intentions of mobile wallet (m-wallet) users. The paper explores the dynamics of perception, behavioral intention motivation and satisfaction of m-wallet users.

Design/methodology/approach

The authors have used a self-administered questionnaire for data collection. A total of 506 responses were analysed using confirmatory factor analysis in conjunction with Structural Equation Modeling, ensuring the validity and reliability of the insights into the behavioral dynamics of m-wallet users.

Findings

The research highlights the direct impact of perceived security on m-wallet users' perceptions, which subsequently influence both direct and indirect behavioral intentions. Moreover, satisfaction emerged as a significant determinant directly shaping behavioral intentions.

Originality/value

This study contributes significantly to the existing literature by offering a comprehensive understanding of the factors driving m-wallet adoption and usage intentions, thereby equipping stakeholders and policymakers with the necessary tools to devise effective strategies to promote mobile payment technologies in North India. The study employs a multifaceted model that incorporates six key elements, providing a comprehensive understanding of the complex interrelationships among these variables.

Abstract

Purpose: The regulatory framework for corporate governance has focused on enhancing transparency, disclosure, and the role of independent directors. The supply side issues have dominated the attempts to enforce better governance. Rising cases of shareholder activism indicate the lacunas in supply-driven governance enforcement. Developing an ecosystem of shareholder engagement will spur demand-driven corporate governance. Shareholder’s active participation provides scope for enforcing good governance. The role of shareholder engagement in enhancing sustainability and value addition has been ignored.

Research methodology: The bibliometric study attempts to explore work done by countries, institutions, and researchers on shareholder engagement to explore the developments in shareholder engagement and the scope for further study. The Scopus online database was used for the study. Bibliometric analysis was done using VOSviewer (version 1.6.18).

Finding: It was found that shareholder engagement attracts researchers’ attention. Developed economies dominate the studies on shareholder engagement. Developing economies have relatively underexplored the concept of shareholder engagement.

Originality/value: Firms diversifying from customer engagement to shareholder engagement have the scope to enhance value addition and sustainability.

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.

This paper aims to study the energy ratios of plane waves on an interface of nonlocal thermoelastic halfspace (NTS) and nonlocal orthotropic piezothermoelastic half-space (NOPS).

Abstract

Purpose

This paper aims to study the energy ratios of plane waves on an interface of nonlocal thermoelastic halfspace (NTS) and nonlocal orthotropic piezothermoelastic half-space (NOPS).

Design/methodology/approach

The memory-dependent derivatives (MDDs) approach with a hyperbolic two-temperature (HTT), three-phase lag theory is used here to study how the energy ratios change at the interface with the angle of incidence.

Findings

Plane waves that travel through NTS and hit the interface as a longitudinal wave, a thermal wave, or a transversal wave send four waves into the NOPS medium and three waves back into the NTS medium. The amplitude ratios of the different waves that are reflected and transmitted are used to calculate the energy ratios of the waves. It is observed that these ratios are affected by the HTT, nonlocal and MDD parameters.

Research limitations/implications

The energy ratios correspond to four distinct models; nonlocal HTT with memory, nonlocal HTT without memory, local HTT with memory and nonlocal classical-two-temperature with memory concerning the angle of incidence from 0 degree to 90 degree.

Practical implications

This model applies to several fields, including earthquake engineering, soil dynamics, high-energy particle physics, nuclear fusion, aeronautics and other fields where nonlocality, MDD and conductive temperature play an important role.

Originality/value

The authors produced the submitted document entirely on their initiative, with equal contributions from all of them.

Abstract

Since 1960s it has been realized that the bilateral trade at international level cannot be explained solely by the classical and neoclassical models of trade based on inter-industry trade. There is an existence of export and import within the same industry among the trading partners. Intra-industry trade (IIT) for products and product groups has been empirically observed by several studies. However, there is not much literature available on IIT in services. So also, from country perspective many studies are based on IIT for advanced countries. There is not much empirical evidence available for IIT among the emerging economies. The study aims to analyze the IIT in tourism services for five major emerging economies constituting BRICS – Brazil, Russia, India, China, and South Africa. The group constitutes 41% of world population with 24% of world GDP and 16% share in world trade. The study used both static and dynamic approaches to measure the IIT between India and other BRICS nations between 2018 and 2020. To empirically estimate the IIT, the study employs Grubel and Lloyd index and Brülhart index (MIIT). The study reveals that India had a very high level of intra-tourism trade with Brazil and South Africa. While with China and Russian Federation it was moderate. Results denote a correlation between the theory of international trade and tourism. There is two-way trade in BRICS tourism flows.

Abstract

Purpose

Tribological research is complex and multidisciplinary, with many parameters to consider. As traditional experimentation is time-consuming and expensive due to the complexity of tribological systems, researchers tend to use quantitative and qualitative analysis to monitor critical parameters and material characterization to explain observed dependencies. In this regard, numerical modeling and simulation offers a cost-effective alternative to physical experimentation but must be validated with limited testing. This paper aims to highlight advances in numerical modeling as they relate to the field of tribology.

Design/methodology/approach

This study performed an in-depth literature review for the field of modeling and simulation as it relates to tribology. The authors initially looked at the application of foundational studies (e.g. Stribeck) to understand the gaps in the current knowledge set. The authors then evaluated a number of modern developments related to contact mechanics, surface roughness, tribofilm formation and fluid-film layers. In particular, it looked at key fields driving tribology models including nanoparticle research and prosthetics. The study then sought out to understand the future trends in this research field.

Findings

The field of tribology, numerical modeling has shown to be a powerful tool, which is both time- and cost-effective when compared to standard bench testing. The characterization of tribological systems of interest fundamentally stems from the lubrication regimes designated in the Stribeck curve. The prediction of tribofilm formation, film thickness variation, fluid properties, asperity contact and surface deformation as well as the continuously changing interactions between such parameters is an essential challenge for proper modeling.

Originality/value

This paper highlights the major numerical modeling achievements in various disciplines and discusses their efficacy, assumptions and limitations in tribology research.
