Abstract
Purpose
This purpose of this paper is to find the approximate analytical solutions of a multidimensional partial differential equation such as Helmholtz equation with space fractional derivatives α,β,γ (1<α,β,γ≤2). The fractional derivatives are described in the Caputo sense.
Design/methodology/approach
By using initial values, the explicit solutions of the equation are solved with powerful mathematical tools such as He's homotopy perturbation method (HPM).
Findings
This result reveals that the HPM demonstrates the effectiveness, validity, potentiality and reliability of the method in reality and gives the exact solution.
Originality/value
The most important part of this method is to introduce a homotopy parameter (p), which takes values from [0,1]. When p=0, the equation usually reduces to a sufficiently initial form, which normally admits a rather simple solution. When p→1, the system goes through a sequence of deformations, the solution for each of which is close to that at the previous stage of deformation. Here, we also discuss the approximate analytical solution of multidimensional fractional Helmholtz equation.

This study illustrates the use of the repertory grid in identifying and assessing effective teaching competencies.
Abstract
Purpose
This study illustrates the use of the repertory grid in identifying and assessing effective teaching competencies.
Design/methodology/approach
The data were collected from two subsamples that consist of business management students and engineering students. The systematic repertory grid (RepGrid) method was performed to identify broad effective teaching competencies.
Findings
Broad effective teaching competencies found in the study include teaching approach, behavioral orientation, subject expertise, and communication skills among others.
Research limitations/implications
Interestingly, the responses of the subsamples differ in the competencies identified and the weights assigned to a particular competency. Further, the results indicate the importance of having a “context” and thereby challenge the concept of generic teaching competencies.
Practical implications
The universities are encouraged to use RepGrid technique to assess effective teaching competencies of their faculty members.
Originality/value
The techniques for developing teaching competency models by some prior studies have several inherent flaws including the efficiency and effectiveness of data collection. The study takes forward the suggestions of scholars to use a rigorous technique, repertory grid, to overcome several of these flaws to a large extent.

The purpose of this paper is to analyse the certified emission reduction (CERs) disclosure and reporting practices followed by Indian firms.
Abstract
Purpose
The purpose of this paper is to analyse the certified emission reduction (CERs) disclosure and reporting practices followed by Indian firms.
Design/methodology/approach
The study is based on all 131 Indian firms who received the CERs under the CDM of UNFCCC. The content analysis is being used to examine the recognition, measurement, presentation and disclosure of CERs within the financial statements.
Findings
The study found that there is generally no uniformity of accounting for CERs. The firms adopted a diversity of accounting practices. More specifically, majority of companies (40.46 per cent) recognised CERs as the other income; a very high non-disclosure rate (91.60 per cent) for valuation of CERs inventories was found as only four companies (3.05 per cent) provided accounting treatment for CERs inventories at lower of cost or net realisable value followed by three companies (2.29 per cent) accounted for these inventories at Net realisable value at the end of the reporting period; similarly, a very high non-disclosure rate (92.36 per cent) for how companies account for expenses incurred in earning these credits was found.
Research limitations/implications
The study will be useful for a wide array of audiences ranging from accounting standard setter to the auditors. The present analysis is based on secondary data, as we examined only annual reports of the sample companies to know how they recognise their earned CERs within the financial statements. So, we did not cover the opinions of various key persons of companies like an accountant, auditors etc. which could be a limitation of this study in validating CERs disclosure practices followed by the Indian firms.
Originality/value
To the best of the author's knowledge, the present study is a first of its kind to analyse the carbon credit disclosure practices in the context of a developing country.

The purpose of this paper is to analyze the relationship between carbon emissions and a firm’s cost of debt (COD) in the Indian context.
Abstract
Purpose
The purpose of this paper is to analyze the relationship between carbon emissions and a firm’s cost of debt (COD) in the Indian context.
Design/methodology/approach
The present study is based on the Indian firms who disclose their emissions data under the Carbon Disclosure Project (CDP) during the period 2011 to 2014. The selection model is being used to remove the problem of endogeneity and sample selection bias. Further, the testing model is being used to examine the impact of carbon emissions on the COD.
Findings
The present study found that the coefficient of carbon emissions is positively and significantly associated with the COD. Moreover, the outcomes of the robustness test further show that the COD will be higher for polluting firms than environmentally friendly firms in India.
Research limitations/implications
The study has covered all the companies from India who are disclosing their emissions data under the CDP, London. The study will be most relevant for financial planning and capital structure design by the Indian companies. However, in designing the capital structure, the only COD is being covered in this study.
Originality/value
To the best of the author’s knowledge, the present study is a first of its kind to investigate the relationship between firms’ carbon emissions level and COD in the Indian context.

Purpose
This study aims to understand the role of university incubation centers (UICs) in fostering startup growth within an academic ecosystem, focusing on enhancing their effectiveness.
Design/methodology/approach
Data was collected from startups and incubation centers in Karnataka, India. Warp partial least squares 6.0 was used for path analysis to examine the relationships between institutional pressures, startup performance and resource acquisition.
Findings
UICs in India effectively support startup growth. Mimetic isomorphism positively influences resource munificence, while normative isomorphism enhances monitoring and assistance. Coercive pressures negatively impact startup performance.
Research limitations/implications
The research is limited to India. Future studies in other developing countries would help validate and extend these findings, offering a more comprehensive understanding of incubation center dynamics globally.
Practical implications
This study offers insights on optimizing UIC operations to better support startups. By integrating institutional theory, it highlights the significance of legitimacy, professional standards and strategic location in enhancing incubation center effectiveness.
Social implications
UICs play a crucial role in bolstering the startup ecosystem, essential for employment generation and economic development in India. Effective incubation centers drive innovation and entrepreneurship, contributing to broader societal benefits.
Originality/value
This study fills a gap by focusing on South Asia, providing insights into the unique challenges and opportunities faced by UICs in developing countries and enhancing understanding of incubation practices in these regions.

Abstract
Purpose
The COVID-19 pandemic has impacted 222 countries across the globe, with millions of people losing their lives. The threat from the virus may be assessed from the fact that most countries across the world have been forced to order partial or complete shutdown of their economies for a period of time to contain the spread of the virus. The fallout of this action manifested in loss of livelihood, migration of the labor force and severe impact on mental health due to the long duration of confinement to homes or residences.
Design/methodology/approach
The current study identifies the focus areas of the research conducted on the COVID-19 pandemic. Abstracts of papers on the subject were collated from the SCOPUS database for the period December 2019 to June 2020. The collected sample data (after preprocessing) was analyzed using Topic Modeling with Latent Dirichlet Allocation.
Findings
Based on the research papers published within the mentioned timeframe, the study identifies the 10 most prominent topics that formed the area of interest for the COVID-19 pandemic research.
Originality/value
While similar studies exist, no other work has used topic modeling to comprehensively analyze the COVID-19 literature by considering diverse fields and domains.
