Abstract

Purpose

This study aims to use new formula derived based on the shifted Jacobi functions have been defined and some theorems of the left- and right-sided fractional derivative for them have been presented.

Design/methodology/approach

In this article, the authors apply the method of lines (MOL) together with the pseudospectral method for solving space-time partial differential equations with space left- and right-sided fractional derivative (SFPDEs). Then, using the collocation nodes to reduce the SFPDEs to the system of ordinary differential equations, which can be solved by the ode45 MATLAB toolbox.

Findings

Applying the MOL method together with the pseudospectral discretization method converts the space-dependent on fractional partial differential equations to the system of ordinary differential equations.

Originality/value

This paper contributes to gain choosing the shifted Jacobi functions basis with special parameters a, b and give the authors this opportunity to obtain the left- and right-sided fractional differentiation matrices for this basis exactly. The results of the examples are presented in this article. The authors found that the method is efficient and provides accurate results, and the authors found significant implications for success in the science, technology, engineering and mathematics domain.

Abstract

Purpose

The purpose of this paper is to decompose total factor productivity (TFP) changes of the agriculture sector in ten African countries.

Design/methodology/approach

A fixed-effects estimation is applied to estimate the translog production function.

Findings

The study results are consistent with previous studies, indicating low TFP. Furthermore, of the TFP components, only technical change (TC) is positive. This study proposes that credit be made available to farmers in Egypt, Morocco, Algeria, and Tunisia. Furthermore, agricultural development programs should be implemented in South Africa and Senegal to improve TFP in these countries.

Originality/value

This study measures the following TFP components for the African agriculture sector: TC, technical efficiency, and scale effects.

Abstract

Purpose

The purpose of this study is to examine the role of financial and nonfinancial information in determining individual investor's investment decisions by analyzing the mediating effect of corporate reputation.

Design/methodology/approach

The approach of this study is deductive; therefore, the quantitative strategy is used for data collection. Primary data are collected from individual investors actively involved in stock trading at Pakistan Stock Exchange (PSX). Structural equation modeling is used to assess structural relationships.

Findings

The key findings of this study posit that financial and nonfinancial information positively influence an individual investor's investment decision. This study also provides empirical evidence confirming the mediating role of corporate reputation. Categorically, the findings indicate that financial and nonfinancial information remain significant to build perceived corporate reputation and influence investor's investment decisions.

Practical implications

he proposed model presents novel insight into the individual investor's investment decision in the context of Pakistan. The findings of this study remain robust for firms listed on the stock exchange and individual investors involved in stock trading. The results of this study are substantial to individual investor's and broker for making informed financial choices. Moreover, the firms listed on the PSX can use the findings to establish improved corporate reputation through reporting detailed financial and nonfinancial information.

Originality/value

Studies based on subjective measures in finance are lacking. This study contributes to the existing literature of behavioral finance by analyzing variations in investor's investment decisions explained by informational factors. The proposed model testifies the mediating role of corporate reputation in guiding investor's investment decisions, which has been overlooked by past studies. Therefore, this study seeks to fill this gap in the context of the PSX.

Abstract

Purpose

This paper aims to investigate whether the effect of competitive strategies on the performance is significantly different for fully fledged Islamic banks vis-a-vis conventional banks with Islamic window. Specifically, two competitive strategies namely the low-cost strategy and the differentiation strategy were considered. In addition, we examined further the competitive strategies–performance nexus by introducing enterprise risk management as a mediating factor.

Design/methodology/approach

This study used structured questionnaires to collect data from 506 respondents (251 from fully fledged Islamic banks and 255 from conventional banks with Islamic window). A disjoint two-stage approach was employed to analyze a hierarchical component model. Construct Level Correction and Measured Latent Marker Variable approaches were employed to assess the common method variance. As a robustness check, two-stage approach was used to explore the curvilinear relationship, and the Gaussian copula approach was adopted to address the endogeneity issue.

Findings

The findings show the evidence of complementary partial mediation in the relationships between low-cost strategy, differentiation strategy, and performance through enterprise risk management practices in both types of banks.

Practical implications

Competitive strategies are essential as they send signals to owners, managers, policymakers, and regulatory authorities. On the one hand, fully fledged Islamic banks face dual competition from pure conventional counterparts as well as conventional banks with Islamic window. On the other hand, Islamic window banks also face strong competition from the fully fledged Islamic banks due to their strong Shariah roots. Hence, this competitive pressure on both types of banks calls for more attention to focus on competitive strategies and enterprise risk management practices to accelerate their performance and overcome the bank risk. Moreover, these competitive strategies can be used as a tool to enter into a new market by reducing costs and risks. Besides, banks cannot achieve a competitive advantage without implementing enterprise risk management practices because competitive strategies are significant antecedents of enterprise risk management practices. Therefore, this study recommends both types of banks to focus on enterprise risk management practices to make these strategies successful.

Originality/value

To the best of our knowledge, this is the first study to examine the competitive strategies–performance nexus and the mediating role of enterprise risk management practices in an unexplored area of Islamic banking.

Abstract

Purpose

This study aims to examine the associations between socioeconomic status, types of rigging (pre- polling-day and post-), politics and voting behavior, vote casting and perceptions of rigging in Pakistan’s most recent elections, and attitudes toward electoral integrity.

Design/methodology/approach

Data were collected from students at three different universities. In all, 748 units of analysis (488 male and 260 female) recorded their responses by means of a self-structured questionnaire. Linear regression was applied to measure the associations between variables, and the reliability and validity of the scales were tested.

Findings

A significant relationship was found between pre-poll rigging, post-poll rigging, politics and voting behavior, socioeconomic characteristics (i.e. age, education, father’s education, background or place of residence and monthly household incomes), the perception of rigging in the last elections and attitudes toward electoral integrity.

Practical implications

Pakistan’s history has been blemished by electoral malpractices during both de facto and de jure regimes. Attention has formerly been paid to either polling-day or post-election rigging. The relationship of electoral integrity with different factors explored in this study have usually been ignored or overlooked. The findings of this study would help policy-makers, youth experts and academicians to reorient their behaviors to strengthen political stability, the rule of law and the continuation of democracy via their participation in the system.

Originality/value

To the researchers’ best knowledge, there has not been a single peer-reviewed study of Pakistan which has explored the associations between the variables examined for this study. The main academic challenge the researchers faced was to find a standardized and contextualized scale or tool to explore how different types of vote-rigging affected attitudes toward electoral integrity. Thus, the structured scales for types of rigging and electoral integrity developed here would be useful for future studies in the field of electoral integrity in democratic countries.

This paper aims to study the effect of concentric hot circular cylinder inside egg-cavity porous-copper nanofluid on natural convection phenomena.

Abstract

Purpose

This paper aims to study the effect of concentric hot circular cylinder inside egg-cavity porous-copper nanofluid on natural convection phenomena.

Design/methodology/approach

The finite element method–based Galerkin approach is applied to solve numerically the set of governing equations with appropriate boundary conditions.

Findings

The effects of different range parameters, such as Darcy number (10–3 = Da = 10–1), Rayleigh number (103 = Ra = 106), nanoparticle volume fraction (0 = ϑ = 0.06) and eccentricity (−0.3 = e = 0.1) on the fluid flow represent by stream function and heat transfer represent by temperature distribution, local and average Nusselt numbers.

Research limitations/implications

A comparison between oval shape and concentric circular concentric cylinder was investigated.

Originality/value

In the current numerical study, heat transfer by natural convection was identified inside the new design of egg-shaped cavity as a result of the presence of a circular inside it supported by a porous medium filled with a nanofluid. After reviewing previous studies and considering the importance of heat transfer by free convection inside tubes for many applications, to the best of the authors’ knowledge, the current work is the first study that deals with a study and comparison between the common shape (concentric circular tubes) and the new shape (egg-shaped cavity).

Abstract

Purpose

Tags are used to annotate resources on social media platforms. Most tag recommendation methods use popular tags, but in the case of new resources that are as yet untagged (the cold start problem), popularity-based tag recommendation methods fail to work. The purpose of this paper is to propose a novel model for tag recommendation called multi-feature space latent Dirichlet allocation (MFS-LDA) for cold start problem.

Design/methodology/approach

MFS-LDA is a novel latent Dirichlet allocation (LDA)-based model which exploits multiple feature spaces (title, contents, and tags) for recommending tags. Exploiting multiple feature spaces allows MFS-LDA to recommend tags even if data from a feature space is missing (the cold start problem).

Findings

Evaluation of a publicly available data set consisting of around 20,000 Wikipedia articles that are tagged on a social bookmarking website shows a significant improvement over existing LDA-based tag recommendation methods.

Originality/value

The originality of MFS-LDA lies in segregation of features for removing bias toward dominant features and in synchronization of multiple feature space for tag recommendation.

This paper aims to examine the effects of oil price uncertainty on corporate investment of Islamic stocks during the COVID-19 pandemic.

Abstract

Purpose

This paper aims to examine the effects of oil price uncertainty on corporate investment of Islamic stocks during the COVID-19 pandemic.

Design/methodology/approach

The study uses a panel data set that covers 398 listed Islamic stocks from seven major Asia Pacific countries over the period of five years from 2017 to 2021, yielding 1,990 observations. Specifically, this paper investigates the said association by combining the real options theory regarding investment and the panel data-based econometric method that captures the dynamic relationship, the generalized method of moments estimators.

Findings

The findings show that the relationship between the oil price volatility and corporate investment of Islamic stocks is significant and nonlinear in nature, suggesting the presence of both the growth options and the waiting options. Overall, the results reveal that corporate investment of Islamic stocks is hindered during the unprecedented corona crash, when oil price increases at exponential rates.

Practical implications

The findings suggest that considering the information caused by unprecedented events like the COVID-19 pandemic is crucial for investment decisions of Islamic stocks. Therefore, policymakers and regulators should incorporate the impact of oil price uncertainties caused by unprecedented events like the COVID-19 pandemic on firm’s investment expansion and diversification strategies.

Originality/value

To the best of the authors’ knowledge, this paper is the first to examine the relationship between the investment of Islamic stocks and the oil price uncertainty under compound options theory in top Asian oil-importing countries.

Abstract

This review shows the systematic and bibliometric review of 361 papers on the impact of corporate social responsibility on firm performance from 2013 to 2023. The aim of this review is to research the development trends of women’s financial inclusion and women’s financial literacy during this period. The outcomes show that the issue of women’s financial literacy and women’s financial inclusion is particularly highlighted by scholars since 2019, especially for 2021 and 2022. This review focusses on two aspects of analysis: publish performance and content. In terms of published performance analysis, the publication information of papers is analysed to understand the publication trends and author’s research trends in this decade, and bibliometric maps are generated using VOS-viewer software. The bibliometric map shows that India and the USA are in the middle of the map which shows that the authors from these two nations have strong correlations with other authors. For the content analysis, we used VOS-viewer software to analyse the content of the title and abstract, the outcomes reveal three main streams about financial literacy and financial inclusion for women, especially in rural regions in developing economics and the suggestions for policymakers and government. This review attempts to cover the systematic and bibliometric analysis by presenting findings through analysis of selected papers, which highlights some possible gaps and opportunities in the literature along with a scope of directions for future research.

Abstract

Purpose

Additive manufacturing (AM) technology has a huge influence on the real world because of its ability to manufacture massively complicated geometrics. The purpose of this study is to use CiteSpace (CS) visual analysis to identify fused deposition modeling (FDM) research and development patterns to guide researchers to decide future research and provide a framework for corporations and organizations to prepare for the development in the rapid prototyping industry. Three-dimensional printing (3DP) is defined to budget minimize manufactured input and output for aviation and the medical product industrial sectors. 3DP has implemented its potential in the Coronavirus Disease of 2019 (COVID-19) reaction.

Design/methodology/approach

First, 396 original publications were extracted from the web of science (WOS) with the comprehensive list and did scientometrics analysis in CS software. The parameters are specified in CS including the span (from 2011 to 2019, one year slice for the co-authorship and the co-accordance analysis), visualization (show the merged networks), specific criteria for selection (top 20%), node form (author, organization, region, reference cited; cited author, journal and keywords) and pruning (pathfinder and slicing network). Finally, correlating data was studied and showed the results of the visualization study of FDM research were shown.

Findings

The framework of FDM information is beginning to take shape. About hot research topics, there are “Morphology,” “Tensile Property by making Blends,” “Use of Carbon nanotube in 3DP” and “Topology optimization.” Regarding the latest research frontiers of FDM printing, there are “Fused Filament Fabrication,” “AM,” in FDM printing. Where “Post-processing” and “environmental impact” are the research hotspots in FDM printing. These research results can provide insight into FDM printing and useful information to consider the existing studies and developments in FDM researchers’ analysis.

Research limitations/implications

Despite some important obtained results through FDM-related publications’ visualization, some deficiencies remain in this research. With >99% of articles written in English, the input data for CS was all downloaded from WOS databases, resulting in a language bias of papers in other languages and neglecting other data sources. Although, there are several challenges being faced by the FDM that limit its wide variety of applications. However, the significance of the current work concerning the technical and engineering prospects is discussed herein.

Originality/value

First, the novelty of this work lies in describing the FDM approach in a Scientometric way. In Scientometric investigation, leading writers, organizations, keywords, hot research and emerging knowledge points were explained. Second, this research has thoroughly and comprehensively examined the useful sustainability effects, i.e. economic sustainability, energy-based sustainability, environmental sustainability, of 3DP in industrial development in qualitative and quantitative aspects by 2025 from a global viewpoint. Third, this work also described the practical significance of FDM based on 3DP since COVID-19. 3DP has stepped up as a vital technology to support improved healthcare and other general response to emergency situations.
