Abstract

This paper examines, based on certain criteria, the most feasible sustainable energy technology (SET) for rural Bangladesh. The criteria used for the appropriateness of SET for rural Bangladesh are: (a) availability of energy resources, (b) degree of technological complexity of the proposed technology, (c) cost effectiveness, (d) balance between supply of and demand for energy, (e) contribution of the particular energy technology to reducing greenhouse gas emission, and (f) major constraints associated with accepting the recommended technology. The paper describes the theoretical part of the author's Ph.D. thesis where fundamental work has been done. The study applies the criteria to three main energy technologies‐ biomass, solar and wind‐ and finds that none of these technologies are suitable on their own. However, among the three proposed energy technologies, biomass might be the best possible option which can make a positive contribution to alleviate energy poverty in rural Bangladesh. Findings of this study are useful for development policy makers and researchers.

Abstract

In recent years, the use of structural equation modeling (SEM) has become widespread in tourism and hospitality research. Because there are two different approaches to SEM (i.e., covariance-based SEM and variance-based, partial least squares SEM), this brings challenges for researchers about which SEM to use and what to report in each SEM approach. Therefore, the purpose of this chapter is to discuss the differences between CB-SEM and PLS-SEM and to provide comprehensive guidelines for researchers on how to apply each SEM. Within this context, the authors first briefly summarize the fundamentals and advantages of using SEM. Then, the authors explain in detail the major issues that should be considered when selecting between CB-SEM and PLS-SEM. Finally, to ensure rigorous research practices, the authors provide step-by-step guidelines for the application of both CB-SEM and PLS-SEM.

The purpose of this paper is to propose a site selection method using grey system theory for a desalination plant in Libya.

Abstract

Purpose

The purpose of this paper is to propose a site selection method using grey system theory for a desalination plant in Libya.

Design/methodology/approach

In order to tackle incompleteness and imprecision of human’s judgments, grey numbers were used. This work uses a grey-based approach to represent decision makers’ comparison judgments and extent analysis method to select the best site. Therefore, a real case study of a selection problem of a site selection of desalination plant in Libya was used to illustrate the proposed approach.

Findings

Site selection in a desalination plant can be one of the most important decisions in planning a desalination project. The decision affects both the project cost and potentially the project schedule. Based on the results of grey model, a clear order of these sites and the degree of preference are obtained. This paper presents a way to improve a site selection by using a grey model, especially in a complex environment like Libya.

Originality/value

To the best knowledge of the authors, there is no literature for site selection using grey system theory in a desalination plant in Libya. This attempt may well enhance and facilitate the decision-making process of the best site in the country involved in this research.

Abstract

Purpose

An increment in energy efficiency by employing nanoparticles is a hot topic of research in present era due to its abundant implications in modern engineering and technological processes. Therefore, the current research analysis reported the viscoelastic nanofluid flow over porous oscillatory moving sheet in the presence of microorganisms. A rate-type fluid namely Maxwell fluid is employed with the addition of nanoparticles. The paper aims to discuss this issue.

Design/methodology/approach

First, acceptable dimensionless variables are defined to convert the system of dimensional form into the system of dimensionless forms. Later on, the self-similar solution of the boundary value problem is computed by using the homotopy analysis method. The obtained results of velocity, temperature, mass concentration and motile microorganism density profiles are interpreted through physical background.

Findings

The presence of both thermophoresis and Brownian motion parameters also improve the thermophysical features of non-Newtonian nanoparticles. It is also pointed out that the presence of porous medium and magnetic force enhances the nanoparticles concentration. Moreover, a weaker distribution of gyrotactic microorganism has been depicted with Peclet number and bioconvection Lewis parameter.

Originality/value

No such article exists in the literature yet.

Abstract

Purpose

This paper aims to shed light on how small- and medium-sized enterprises can use export promotion programmes (EPPs) to improve their performance. The proposed conceptual model focuses on the need that the mechanism of awareness and use of EPPs should play a more active strategic role in shaping the firm’s export performance.

Design/methodology/approach

A meta-analysis of the pertinent literature reveals 16 studies on EPPs.

Findings

This study reveals that there are 16 relationships which are important based on the meta-analytic correlations. The analysis of these relationships shows that EPPs, export performance, strategy, knowledge, commitment, capabilities, competitive advantage and experience are the mostly used constructs.

Originality/value

This investigation supports the view that the moderating effects of the improvement of trust relationship between partners, i.e. importers to exporter and public policymakers to exporter, and the mechanism of awareness and use of EPPs accelerate the firm’s export performance. EPPs explain 31.3 per cent of the variance in export performance indicating their catalytic role in the exports’ growth.

Abstract

Purpose

This study aims to find out how pomposia fruit powder (Syzygium cumini L.) mixed with roasted coffee (RCO) affected antioxidants, phytochemicals, lipid peroxidation inhibition and sensory attributes.

Design/methodology/approach

Pomposia fruits (Syzygium cumini L.) powder (PFP) was integrated with RCO at levels of 0.0%, 5.0%, 10.0%, 15.0% and 20.0%. RCO, PFP and binary mixtures containing RCO: PFP were evaluated for their total phenolics (TP), total flavonoids (TF), anthocyanin content (AC), antioxidant activity and phenolic compounds fractionation. The oxidative indices of coffee oil samples were measured throughout different storage intervals. Additionally, sensory characteristics of RCO enriched with different PFP doses were evaluated.

Findings

PFP samples exhibited the greatest TP content (1910 mg/100 g), whereas RCO samples had the lowest concentration (1090 mg/100 g). As more PFP was added, the corresponding coffee blends’ concentrations of TP, TF and AC were improved significantly. PFP possesses a radical-scavenging activity that is about 1.20 times more than RCO’s. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging activity jumped significantly from 74.13% in control (untreated) samples to 77.64%, 78.39% and 80.15% for samples enriched with 10.0%, 15.0% and 20% PFP, respectively. Significant increases in gallic acid, hesperidine, benzoic acid, chlorogenic acid, hispertin, catechol, quercetin, pyrogallol and rutin were detected when RCO was mixed with different quantities of PFP. At the end of storage trial, the coffee oil treated with 20% PFP had AV, PV and TBA values that were about 1.70, 1.95 and 1.66 times lower, respectively, than those of the control sample that had not had PFP addition. The RCO with 5.0% PFP achieved the greatest over acceptability grades.

Originality/value

To the best of the authors’ knowledge, this study was the first study to evaluate the effect of incorporating various level of pomposia fruit powder into RCO. The findings shows that adding different concentrations of pomposia fruit powder into RCO can indeed enhance the radical-scavenging activity of the coffee and potentially extend its shelf life.

Abstract

Purpose

This study aims to examine the influence of the quality of voluntary disclosure (QVD) on earnings management (EM) amongst a sample of commercial banks in the Middle East and North Africa (MENA) region.

Design/methodology/approach

Using a sample of 1,060 bank-year observations for the period 2006–2015, this paper developed a three-dimensional framework to measure the QVD, which considers the quantity, spread and usefulness of the information. Furthermore, this study examines the QVD-EM nexus using an ordinary least squares regression model. This technique is supplemented with conducting an instrumental variable regression model and a two-stage least squares model to overcome the potential occurrence of endogeneity problems.

Findings

The findings suggest that QVD is negatively attributed to EM in the context of MENA banks. The findings also confirm that the quality of financial reporting is enhanced by QVD dimensions that were considered in the framework, leading banks to less engagement in EM practices. In contrast, the influence of the quantity dimension (level) of the disclosed information has an insignificant impact on EM, while the spread and usefulness dimensions of VD are negatively and significantly associated with EM in the region.

Research limitations/implications

Although the results are robust to various measurements and to the possible occurrence of endogeneity problems, there are a few limitations should be acknowledged, which provides opportunities for future research. For example, the sample size is relatively small due to data accessibility issues. Likewise, the findings of the research might not be appropriate for non-financial sectors. These limitations provide a good opportunity for future studies to expand on the research by covering other developing economies and, thereby, enriching the understanding offered by this study.

Practical implications

This study offers several implications for bank managers, academics and policymakers. Firstly, it may help managers to appreciate the function and the importance of QVD in mitigating EM. Secondly, for academics, the study provides suggestive evidence on the impact of QVD on EM; however, future research may need to consider the role of morality and ethical behaviour across different environments in reducing excessive risk-taking and constraining earnings manipulation. Finally, it provides insights for policymakers and regulators to develop a framework or guidance that can help banks in providing high-QVD in the context of developing economies.

Originality/value

The study distinctively develops an innovative measurement for QVD using a new multi-dimensional model. This paper also bring new evidence on QVD complexity and its impact on EM practice from an under-researched developing context, namely, the MENA region.

Abstract

Purpose

This study aims to contribute to the International Business literature by investigating the marketing stimuli that drive impulsiveness and perceived value in mobile shopping (MS) platforms and their impact on consumer response.

Design/methodology/approach

This study uses a sample of 891 MS platform users and applies structural equation modeling based on the stimulus–organism–response and the consumption value theory.

Findings

The empirical finding revealed that rewards, recognition, reviews and ratings are the most influential factors driving perceived value. In addition, the results indicated that customized offerings and visually appealing experiences were the most critical factors affecting the state of impulsiveness. This study also highlights the negative impact of the ubiquitous nature of MS on impulse buying behavior, emphasizing the importance of providing consumers with tools to make informed decisions. This study demonstrates a significant positive relationship between perceived value and impulsiveness, influencing MS.

Practical implications

This study reveals generational differences in the impact of reviews and ratings on perceived value, which can inform businesses’ MS strategies. The results have implications for managers of international firms seeking to optimize their business strategies.

Originality/value

To the best of the authors’ knowledge, using structural equation modeling, this study is the first to conduct a comprehensive examination of marketing stimuli, impulsiveness and perceived value in MS platforms. It offers businesses strategic insights by identifying rewards, recognition and customized offerings as the key determinants of consumer behavior.

Abstract

Purpose

Previous research suggests the crucial role of parents in developing social behaviors of their children. However, less evidence is available on the role of parents in shaping responsible financial management behavior among children for their later life. This study bridges this gap by investigating the role of financial parenting in improving well-being among young Saudi people. Particularly, this study examines the role of financial parenting, childhood financial socialization and childhood financial experiences in developing responsible financial self-efficacy and financial coping behaviors to determine financial well-being among young adults in Saudi Arabia.

Design/methodology/approach

This study uses a two-step mixed-method approach comprising analyses of symmetric (net effects) and asymmetric (combinatory effects) modelling to test the proposed model. A symmetrical analysis examines the role of financial parenting factors that are sufficient for improving financial well-being among Saudis. An asymmetrical analysis is used to explore that a set of combinations of financial parenting conditions lead to high performance of financial well-being. Data have been collected from 350 students enrolled in undergraduate and postgraduate programs in Saudi Arabia.

Findings

According to asymmetric modeling (i.e. fsQCA) analysis, parents and practitioners can combine financial parenting, childhood financial socialization and childhood financial experiences along with financial self-efficacy and financial coping behaviors in a way that satisfied the conditions (i.e. causal antecedent conditions) leading to high financial well-being. Importantly, the condition of high financial well-being is not mirror opposite of causal antecedent conditions of low financial well-being.

Research limitations/implications

This study contributes to the current knowledge by applying both symmetrical and asymmetrical modelling to indicate a high level of financial well-being. Besides, there is sparse empirical evidence available in the context of Saudi Arabia on how financial parenting, socialization and financial experiences in childhood improve children's financial well-being in their later life.

Practical implications

According to asymmetric modeling (i.e. fsQCA) analysis, parents and practitioners can combine financial parenting, childhood financial socialization and childhood financial experiences along with financial self-efficacy and financial coping behaviors in a way that satisfied the conditions (i.e. causal antecedent conditions) leading to high financial well-being. Importantly, the condition of high financial well-being is not mirror opposite of causal antecedent conditions of low financial well-being. The parents and practitioners must be cautious to regulate the condition in which the combination of the antecedents is not in line with the causal recipes of financial well-being negation.

Originality/value

This study deepens the current knowledge by employing both symmetrical and asymmetrical analysis for testing structural and configurational models indicating the high performance of financial well-being . The study proposes and tests an integrated model to bring new contributions to prior literature. This study also attempts to propose valuable research directions for future researchers interested in the topic.

Abstract

Purpose

The current research proposes a model that integrates certain psychological and demographic factors in developing and strengthening young Saudi women's perceptions of entrepreneurial resourcefulness, which eventually may lead to the development and enhancement of their entrepreneurial intentions. The study also examines the ways in which changing socio-cultural norms and values may augment investments and/or efforts to enhance cognitive enablers, including entrepreneurial resourcefulness, and thereby build and strengthen entrepreneurial intentions among female entrepreneurs (i.e. human capital) in a transitioning society. Saudi Arabia is a relevant research context because the Saudi government has invested enormous resources to develop the country's human capital, particularly Saudi government intends to enhance Saudi women's participation in entrepreneurial spheres to be enhanced significantly. Saudi Arabia is undergoing a radical socio-cultural transition, and the kingdom seeks to capitalise on this ongoing transformation to further encourage women to tap into their under-utilised potential. This study seeks to corroborate such moderation effects.

Design/methodology/approach

The authors utilise the intellectual capital (IC) framework and theory of planned behaviour (TBP) to propose the conceptual model in this study. Using a sample of 628 young female respondents – potential entrepreneurs studying at various universities in Saudi Arabia, the authors test the hypothesised associations through partial least squares (PLS)-based path modelling.

Findings

The authors found a significant positive impact of psychological factors, such as perceived behavioural control, attitude towards entrepreneurship, subjective norms and entrepreneurial self-efficacy, on the development and enhancement of perceived entrepreneurial resourcefulness. In addition, demographic factors, including family income, family background, family business experience and entrepreneurship education, play a significant positive role in enhancing individuals' entrepreneurial resourcefulness perceptions. The authors further found that enhanced perceptions of perceived entrepreneurial resourcefulness develop and enhance entrepreneurial intentions among female entrepreneurs. However, the transformation in social and cultural norms significantly moderates this cause and effect relationship.

Originality/value

This study is among the first of its kind to investigate the moderating effects of social and cultural transformation on efforts and/or investments to enhance intellectual capital (more specifically, human capital) and thereby promote entrepreneurship. The study is also valuable for its focus on a unique context, i.e. female entrepreneurship in the Middle East and, more specifically, Saudi Arabia. The study offers useful insights and implications both for theory and practice, particularly for policymakers seeking to augment their intellectual capital formation efforts through an effective orchestration of socio-cultural transformation, which seeks to empower female entrepreneurs to succeed in the face of significant socio-cultural impediments.
