Abstract
Purpose
The purpose of this study is the comprehensive numerical assessment of multidirectional (1D/2D/3D) functionally graded composite panel structures with different material gradation patterns and degrees of material heterogeneity. Here, deformation characteristics are obtained under different loading and support conditions.
Design/methodology/approach
The finite element solutions of multidirectional functionally graded composite panels subjected to uniform and sinusoidal transverse loads are presented under different support conditions. Here, different functionally graded composites, such as unidirectional (1D) and multidirectional (2D/3D), are considered by distributing constituent materials in one, two and three directions, respectively, using single and multivariable power-law functions. A constitutive model with fully spatial-dependent elastic stiffness is developed, whereas the kinematics of the present structure is defined using equivalent single-layer higher-order theory. The weak form, based on the principle of virtual work, is established and solved consequently using isoparametric finite element approximations via quadrilateral Lagrangian elements.
Findings
The appropriate mesh-refinement process is carried out to achieve the mesh convergence; whereas, the correctness of proposed heterogeneous model is confirmed through a verification test. The comprehensive numerical assessment of multidirectional functionally graded panels under various loading and support conditions depicts the importance of degree of material heterogeneity with different gradation patterns and volume-fraction exponents.
Originality/value
A comprehensive analysis on the deformation behaviour of 1D-functionally graded materials (FGMs) (X-FGM, Y-FGM and Z-FGM), 2D-FGMs (XY-FGM, YZ-FGM and XZ-FGM) and 3D-FGM composite panels FGM structures is presented. Multifaceted heterogeneous FGMs are modelled by varying constituent materials in one, two and three directions, using power-law functions. The constitutive model of multi-directional FGM is developed using fully spatial-dependent elastic matrix and higher-order kinematics. Isoparametric 2D finite element formulation is adopted using quadrilateral Lagrangian elements to model 1D/2D/3D-FGM structures and to obtain their deflection responses under different loading and support conditions.

This study aims to understand the relative intensity of the challenges and problems faced by small-scale entrepreneurs in Uttarakhand.
Abstract
Purpose
This study aims to understand the relative intensity of the challenges and problems faced by small-scale entrepreneurs in Uttarakhand.
Design/methodology/approach
A survey methodology was used for this study. The judgement sampling method was used to select the sample for this study. The data were collected from 240 small-scale entrepreneurs using a self-structured questionnaire. Descriptive statistics, principal component analysis and confirmatory factor analysis were used to analyse the data.
Findings
The survey found that marketing, finance, taxation, human resource and government support–related problems are the major problems of small-scale entrepreneurs in the state.
Research limitations/implications
This study was conducted in both rural and urban areas, but due to the unreachability of rural entrepreneurs, the representation of rural entrepreneurs is less, so the findings are more inclined towards urban entrepreneurs.
Practical implications
The research has highlighted the intensity of the major problems faced by small-scale entrepreneurs in Uttarakhand. Although many support schemes are operational in the state, small–scale entrepreneurs face many challenges, so this study provides solutions for those challenges.
Originality/value
This study is unique in that it measures the intensity of problems and challenges of small-scale entrepreneurs and provides insight into more serious issues prevalent in the state.

Abstract
Purpose
The purpose of this study is to segment mobile wallet users using a finite mixture partial least squares (FIMIX-PLS) approach and evaluate the unobserved heterogeneity across segments.
Design/methodology/approach
Partial least square structural equation modeling (PLS-SEM) using a convenience sample of 744 responses was used to analyze the measurement, structural model and hypotheses testing. To examine unobserved heterogeneity and identify user segments, FIMIX-PLS technique was employed. To generate more precise recommendations, importance-performance map analysis (IPMA) was performed with attitude as the target variable.
Findings
A structural equation model revealed that except perceived ease of use (PEOU) all other dimensions, namely perceived usefulness (PU), lifestyle compatibility (LC), facilitating conditions (FC), trust and security significantly influences attitude which, in turn, determines intention. The FIMIX-PLS technique resulted in four segments – The Rationalist, Early Adopters, Late Adopters and The Innovators.
Practical implications
The paper provides segment specific and between segment differences to derive implications. Identification of relevant predictors and segments will help academicians, marketing researchers and practitioners in gaining further understanding of the mobile wallet adoption. The findings of the paper can guide mobile wallet providers to frame appropriate strategies and offerings pertaining to the obtained segments.
Originality/value
The paper builds upon Technology Acceptance Model (TAM) to propose an integrated model to explain adoption behaviors associated with mobile wallet. To the best of the authors' knowledge, this is one of the first empirical attempts using FIMIX-PLS technique to assess precursors of adoption and substantiates the perceived value-attitude-intention linkage to identify heterogeneity among mobile wallet users.

Abstract
“NTL suffered huge losses in its foreign exchange hedging activities as its highly complex leveraged structured products backfired badly in the wake of the Global Financial Crisis of 2007 and 2008. The CFO and the Treasury head have both been sacked, and Joshi, the new CFO, has embraced aggressive litigation as NTL's survival strategy to cope with the losses that threaten its solvency. In the meantime, NTL also faces tax investigations and whistleblower allegations of fraud, and it finds that the record-keeping of its derivative transactions was hopelessly incomplete and patchy. A complete reconstruction of the entire derivative transaction history is the only way to rebuild trust, and that task falls on Reddy, a seasoned derivatives expert brought in by the Board specifically for this purpose.
In this dire situation, Seth, the founder Chairman of NTL decides that NTL needs to put all this behind it and focus on rebuilding the business. The challenge for Seth, Joshi and Reddy is to go about doing this in an environment that offers very few rays of hope.”

This study aims to examine the underlying determinants that may influence external audit fees paid by Emirati nonfinancial companies listed on Dubai Financial Market (DFM).
Abstract
Purpose
This study aims to examine the underlying determinants that may influence external audit fees paid by Emirati nonfinancial companies listed on Dubai Financial Market (DFM).
Design/methodology/approach
Data used in this study are mainly collected from the 2011 annual reports and corporate governance reports published by the Emirati nonfinancial companies listed on DFM. Backward regression analysis is used to measure the impact of a set of company characteristics on Emirati non-financial listed firm’s audit delays.
Findings
The findings pointed to a significant and positive association between audit fees and each of corporate size and audit committee independence variables. A significant and negative relationship has been detected between external audit fees and business complexity. The findings also revealed that audit fees are not significantly associated with company’s profitability, risk, industry type, status of audit firm and audit report lag.
Originality/value
The paper helps in expanding limited existing literature about the determinants of audit fees in the Arab and Middle East countries generally and in the UAE context particularly. No prior attempt had been made to investigate the determinants of audit fees paid by Emirati firms listed on DFM because the disclosure of audit fees services provided by external auditors only became effective after April 30, 2010. The findings of the study may be generalized to other Arab countries, particularly neighboring Gulf Cooperation Council states, that have a similar socio-cultural environment.

Abstract
Purpose
The study investigates the structure of audit fees in an emerging economy, Jordan.
Design/methodology/approach
The following regression model will be tested: ADFEES = f (SIZE, AUST, COMP, INDS, PROF, RISK, YEND, TLAG). The model is tested by running a cross‐sectional linear ordinary least squares (OLS) regression of the audit fees on corporate size, the status of the audit firm, the degree of corporate complexity, profitability, risk, corporate accounting year end and the lag between the audit report and the end of the accounting year.
Findings
The results of the analysis revealed that corporate size, status of the audit firm, industry type, degree of corporate complexity and risk are the main determinants of audit fees. However, variables such as corporate profitability, corporate accounting year‐end (YEND) and time lag between YEND and the audit report date appeared to be insignificant determinants of audit fees.
Research limitations/implications
In order to generalize the outcome of the study, the same study needs to be conducted over a long period of time (five years). Other variables such as the market share of the audit firm and the economic conditions of the country need to be included in the regression model in future research.
Originality/value
The outcome of the study can be used by audit firms to determine audit fees. Companies' management can also use the results of the study to predict the amount of audit fees that they will pay.

Abstract
Purpose
Coronavirus disease 2019 (COVID-19) outbreak has impacted catastrophically every sector of the economy throughout the world. And, the education sector is not leftover from the devastating effects of lockdown, especially in South Asia. It has led to the prolonged closure of schools/universities, subsequently, traditional teaching expeditiously transformed into online teaching. In the light of the events, this study is pertinent to examine teachers’ perceptions of online teaching and the obstacles they face in online teaching during this pandemic.
Design/methodology/approach
The research takes a quantitative and sample survey approach. A Google Form Questionnaire was used to obtain a sample of 200 Delhi school teachers in March and April 2021. Data were analyzed in SPSS by using Descriptive Statistics, Factor Analysis, Reliability and Chi-Square test, etc.
Findings
The result of the study indicates that on average, teachers have a positive perception about virtual teaching amid COVID-19 for reducing the learning gap and shaping pupils’ future during the crisis. Nevertheless, they encountered several obstacles in online teaching such as technical obstacles, difficulties in online exams and assessment, etc.
Practical implications
The findings of this study would persuade educational institutions and policymakers for enhancing the quality of online teaching by embracing the newest instructional strategies and providing continuous training to teachers.
Originality/value
Several studies described obstacles confronted by instructors in virtual teaching in higher education during the Coronavirus while disregarding the perception and challenges of school teachers toward e-learning in an ongoing outbreak. The present study replenishes this gap.

This study examines the causal relationship between intellectual capital and asset quality of banks in Ghana.
Abstract
Purpose
This study examines the causal relationship between intellectual capital and asset quality of banks in Ghana.
Design/methodology/approach
Using annual data extracted from audited financial statements of 24 banks from 2006 to 2015, a ratio of non-performing loans to gross loans and advances is employed to estimate asset quality growths while the value-added intellectual coefficient by Pulic (2008, 2004) measures intellectual capital. The panel-corrected standard errors estimation technique is used to estimate panel regressions with asset quality as the dependent variable.
Findings
Asset quality of banks in Ghana is generally not affected by intellectual capital. However, when intellectual capital is divided into its components, the study indicates that there are significant positive relationships between asset quality and two components of intellectual capital. Thus, structural capital and human capital efficiencies positively affect the asset quality of banks.
Practical implications
The findings of the study implore managements of banks to increase structural and human capital investments and efficiencies to improve asset quality. Furthermore, the results have direct implications on developments in financial markets in emerging economies.
Originality/value
The study analyses the link between typical intellectual capital and asset quality of banks which is yet to be empirically examined in an emerging banking market.

Abstract
Purpose
The purpose of this research is to qualitatively investigate, through a literature review of past studies and an in‐field case study, three different hypotheses regarding women working in the IT sector and their career and promotional aspirations.
Design/methodology/approach
An online survey was used for data collection from female employees with varying professional specializations across several IT departments within the company. Questions for the survey were designed from the findings of the literature review.
Findings
The results obtained have proven that married women who are intrinsically inspired to maintain their work‐family balance face higher stress and more conflicts than those who do not. In addition, the glass ceiling was still evident in today's corporations, but mainly affecting the older generation of women professionals. Also, the results slightly hinted at a ten‐year cut‐off period, after which promotional aspiration is lost.
Research limitations/implications
Owing to the limitations of the research conducted, further qualitative studies can be done to compare careers and promotional patterns between men and women in the IT departments, as well as those between women in IT departments and women working in other departments.
Practical implications
Employers should strive to provide their female employees with practical solutions to allow for an easier balancing of work‐family responsibilities, such as flexi‐time and telecommuting. At the same time, the employers should place the female employees in more opportunity‐enhancing positions within the corporation so that they can exploit or utilize their talents and increase the probability of climbing up the corporate ladder.
Originality/value
With a generous response rate, this paper provides a realistic perspective of professional females working within the IT domain with regard to their career and promotional aspirations.

Abstract
Purpose
This study aims to identify the characteristics of Muslim Generation Z and analyze the factors that influence its purchase intention of environmentally friendly halal cosmetic products.
Design/methodology/approach
This research adopts the quantitative methods of a questionnaire and sampling technique using purposive sampling. The respondents in this study were 300 Indonesian Muslims from Generation Z. Descriptive analysis and structural equation modeling–partial least structural with SmartPLS 3.3.7 software were used to analyze the research data.
Findings
This study found that of the nine hypotheses tested, seven are confirmed, including the effect of halal labels on halal-green awareness, environmentally friendly labels on halal-green awareness, environmental knowledge on halal-green awareness and knowledge on attitudes. Meanwhile, religiosity and halal-green awareness influence attitudes and attitudes that affect the purchase intention of environmentally friendly halal cosmetics. Two hypotheses that are not accepted are the influence of religiosity on halal-green awareness and halal-green awareness on attitudes. The findings are expected to increase interest in buying environmentally friendly halal cosmetics by better understanding consumer behavior, especially Generation Z.
Practical implications
Cosmetics manufacturers benefit from halal-green branding on their products to enter new halal markets and increase market share.
Originality/value
This study is more comprehensive than previous studies, combining halal and environmentally friendly elements with a focus on Generation Z.
