Abstract

Purpose

This study aims to examine the relationship between the risk-aversion level of return policies and customer trust in online shopping in three countries in the Middle East.

Design/methodology/approach

In the first step, the different types of return policies of online shoppers and the risk-aversion level were determined by surveying 18 online shops and interviewing 21 customers. The risk-aversion level of these policies was found in the experts’ panel. In the second step, the experiences of 573 consumers when facing seller’s return messages, perceived risk and consumer trust in three countries (UAE, Iraq and Iran) were collected through a questionnaire. Finally, the gathered data were analyzed using structural equation modeling.

Findings

The results indicated that risk-averse return policies taken by online vendors led to lower consumer trust. Moreover, customer perceived risk mediated the relationship between return policies’ risk-aversion level and trust in Iraq and Iran. At the same time, there was no significant association between return policies and perceived risk in UAE. In addition, perceived risk wholly mediated the relationship between return policies’ risk aversion and trust in vendors in Iran, but this role was minor in Iraq.

Originality/value

Among the intercultural studies, especially in the Middle East, this is one of the first studies based on the marketing and sales management in an online shopper’s supply chain. Moreover, the investigation of return policies in online commerce is another innovative aspect of the present paper.

Abstract

This study examines the association between the use of strategic management accounting (SMA) practices and competitive advantage and the moderating role of four aspects of organisational culture – teamwork orientation, outcome orientation, innovation orientation and attention to detail orientation – on this association. Online survey data were collected from 408 accountants in Australian business organisations, and structural equation modelling (SEM) was used to analyse the data. The results indicate a positive association between the use of SMA practices and competitive advantage with such an association positively moderated by one cultural dimension, teamwork orientation. Specifically, the findings indicate that the positive effect of SMA practices on competitive advantage is dependent upon the fit between the use of SMA practices and teamwork orientation with more (less) teamwork-oriented organisations exhibiting a stronger (weaker) association between the use of SMA practices and competitive advantage.

Abstract

Purpose

An excessive increase in temperature will reduce the lifespan and even burn the coil. The variety of materials in the structure of the electromagnet along with its multi-layer winding creates a complex and heterogeneous thermal structure. There are very few researches that are completely focused on the thermal analysis of electromagnets. The purpose of this paper is to provide an accurate, yet fast and simple method for the thermal analysis of cylindrical electromagnets in both transient and steady-state modes. For this purpose, a thermal equivalent circuit (TEC) is presented based on the nodding approach.

Design/methodology/approach

The results of TEC analysis of cylindrical electromagnet, for two orthogonal and orthocyclic winding coil technologies, were compared with the results of the thermal simulation in COMSOL. The authors also built a laboratory model of the cylindrical electromagnet, similar to those analyzed and simulated, and measured the temperature in different parts of it.

Findings

The comparison of the results obtained from different methods for the thermal analysis of the cylindrical electromagnet indicates that the proposed TEC has an error of less than 2%. The simplicity and high accuracy of the results are the most important advantages of the proposed TEC.

Originality/value

Comparing the information and results related to winding schemes, indicates that the orthogonal winding has less cost and weight due to the shorter length of the wire used. On the other hand, orthocyclic winding generates lower temperature and has more lifting force, and is simpler to implement. Therefore, in practice, orthocyclic winding technology is usually used.

Abstract

Purpose

The low carbon steel used in industrial water conveying pipes in the Dora refinery is corroded. This study aims to reduce corrosion rate in these pipes by using green inhibitor extracted from dill plant. This inhibitor is sustainable environmentally.

Design/methodology/approach

The inhibitor extracted from the dill plant was added at different temperatures (25, 40, 60 and 80°C) and at a fixed concentration of 1,400 ppm, as the best protection was obtained at this concentration. The study was carried out under the same conditions using a polarization technique and scanning electron microscope.

Findings

From the results obtained from the polarization curves, it was found that the inhibition efficiency was 92.12% at a concentration of 1,400 ppm and a temperature of 20°C. Potentiodynamic curves showed that both cathodic and anodic reactions were affected by the addition of the inhibitor, indicating that the used inhibitor acted as a mixed type inhibitor, which means that the addition of these inhibitors to the industrial water reduced the anodic dissolution of iron and also retarded the cathodic hydrogen evolution reaction. This reveals that the inhibition mechanism is of the mixed type with a predominant anodic reaction. The results of the fourier transform infrared test indicated that the dill plant contained different chemical bonds (C–H, C = O, S = O, N–O and C–N) that were included in the construction of the barrier layer to protect the steel surface from corrosion.

Originality/value

The dill plant is abundant in nature, its cost is low and its extraction is very easy. It can be used as an environmentally friendly inhibitor to reduce the rate of corrosion in water-carrying pipes used in oil refineries because it contains effective groups (aromatic rings) that combine with metal atoms to form strong bonds that stick to the surface of the metal, which protect it from the attack of the corrosive medium.

Abstract

Purpose

The aim of this study is to approach the way in which corporate governance influences the occurrence of financial fraud, as expressed by the M-Beneish score. In order to get further into the topic, we have first computed a corporate governance score based on the comply-explain statement and then selected a few elements that are part of the corporate governance reporting: equilibrium of board members (EQUIL), independence of board members (INDEP), selection of the board members (NOM), remuneration policy (REM), audit committee (AUDIT) and the proportion of female directors on boards (GenF). They were tested, one by one, using the financial fraud score to see the way in which they interact.

Design/methodology/approach

The study is conducted on a sample of 65 companies listed on the Bucharest Stock Exchange (BSE) for the 2016–2022 period. The data were processed using three-stage general least square [general least squares (GLS), with iteration, igls and option] with a common first-order panel-specific autocorrelation correction, so as to explain how a poor adoption of the corporate governance score and its elements has a negative implication for the M-Beneish score, controlling for the auditor opinion, type of auditing company and if the company is privately owned.

Findings

The results support most of our research hypothesis, revealing that a poor adoption of the corporate governance score and its components – AUDIT, EQUIL, INDEP and GenF – negatively influences the M-Beneish score, i.e. a low corporate governance score will lead to an increase in financial fraud. This is an encouraging aspect, for an improved adoption of the corporate governance principles reduces the occurrence of financial fraud.

Research limitations/implications

This is a study that concerns the relationship between corporate governance and financial fraud for the case study for Romania.

Practical implications

The study highlights the importance of adopting the corporate governance code applied to the Romanian business environment. By measuring the presence of financial fraud appearance through the M-Beneish score, we have managed to outline the negative relationship between the two components. Thus, it is an important aspect of which companies should take account, so they will have long-term benefits and ensure the continuity of the business.

Social implications

The policy implications of this project are for policymakers, so that they will understand how a good corporate governance mechanism will enhance high-performing businesses. Different aspects regarding corporate governance were validated and are in the process of being validated. Managers can extract and try to understand and apply the good characteristics of corporate governance for the well-being of their companies. At a broader level, the macroeconomic environment will increase its own well-being while encouraging market players to enhance qualitative corporate governance reporting. There is no doubt that corporate governance has a positive impact on businesses.

Originality/value

The study highlights the importance of adopting the corporate governance code as applied to the Romanian business environment. By measuring the occurrence of financial fraud using the M-Beneish score, we have managed to outline the negative relationship between the two components. Therefore, this is an important aspect that companies should take into account in order to have long-term benefits and ensure the continuity of their business.

Abstract

Purpose

The purpose of this study is to empirically evaluate the audit expectations gap among stakeholders in listed firms in Palestine. The purpose of the investigation is to determine whether or not there is a gap in audit expectations between auditors and investors, auditors and board directors, as well as among auditors and financial managers and also among auditors and shareholders.

Design/methodology/approach

To attain its ultimate objective, this study was created using an exploratory descriptive methodology grounded in the use of quantitative methods. A structured questionnaire was used to gather study data from 81 respondents, and a statistical package for the social sciences-26 was then used for analysis.

Findings

The results of this research showed that there is a sizable difference in audit expectations among shareholders, financial managers and board directors, as well as among auditors and investors. The findings also demonstrate that, in comparison to the difference between auditors and financial managers, the gap between auditors and board directors and auditors and shareholders is very narrow.

Research limitations/implications

This investigation, which examines the audit expectations gap in great detail, has some significant limitations. This study was limited to the Palestinian market alone. Future research might compare or examine the variations in audit expectations in Jordan, Lebanon, Syria, Iraq and Iran, among different countries. In addition, the demand for accurate and reliable financial reports has sparked a recent increase in interest in auditing, a long-standing sector that has expanded in recent years.

Practical implications

The study has several practical implications, for example, it underlines how crucial it is to make stakeholders aware of the limitations and difficulties related to the auditing process. By doing this, the situation that audit committees and listed firms find themselves in will be easier for investors, board directors, financial managers and shareholders to understand. The way that auditors and stakeholders communicate can help reduce this gap since it affects how much each party underestimates or understates the other’s obligations.

Originality/value

This paper contributes to the literature by analysing and identifying the causes of the audit expectations gap in companies listed on the Palestine Stock Exchange and providing useful insights and potential solutions to close or mitigate it. It also adds a new contribution to the literature related to the audit expectation gap. This investigation offers unambiguous evidence of a sizable discrepancy between audit expectations and actual performance in terms of formal auditor obligations as outlined by current law, as well as auditor reliability standards and practices, between auditors, board directors, investors, shareholders and financial managers in listed Palestinian firms.

Abstract

Purpose

This study aims to focused on conducting a comprehensive assessment of the technology readiness level (TRL) of Iran’s oil field intelligence compared to other countries with similar oil reservoirs. The ultimate objective is to optimize oil extraction from this field by leveraging intelligent technology. Incorporating intelligent technology in oil fields can significantly simplify operations, especially in challenging-to-access areas and increase oil production, thereby generating higher income and profits for the field owner.

Design/methodology/approach

This study evaluates the level of maturity of present oil field technologies from the perspective of an intelligent oil field by using criteria for measuring the readiness of technologies. A questionnaire was designed and distributed to 18 competent oil industry professionals. Using weighted criteria, a mean estimate of oil field technical maturity was derived from the responses of respondents. Researchers evaluated the level of technological readiness for Brunei, Kuwait and Saudi Arabia’s oil fields using scientific studies.

Findings

None of the respondents believe that the intelligent oil field in Iran is highly developed and has a TRL 9 readiness level. The bulk of experts believed that intelligent technologies in the Iran oil industry have only reached TRL 2 and 1, or are merely in the transfer phase of fundamental and applied research. Clearly, Brunei, Kuwait and Saudi Arabia have the most developed oil fields in the world. In Iran, academics and executive and contracting firms in the field of intelligent oil fields are working to intelligently develop young oil fields.

Originality/value

This study explores the level of maturity of intelligent technology in one of Iran’s oil fields. It compares it to the level of maturity of intelligent technology in several other intelligent oil fields throughout the globe. Increasing intelligent oil fields TRL enables better reservoir management and causes more profit and oil recovery.

Abstract

Purpose

Most developing countries, such as Sri Lanka (SL), are now looking for the support of foreign construction companies for large-scale infrastructure projects in return for expertise and resources. Thus, foreign companies may enter into agreements with local contractors through joint ventures (JVs). However, the priorities of construction project stakeholders may differ, which may ultimately end up in conflicts. Therefore, this research aims to investigate the most suitable conflict management strategies for international construction JVs (ICJVs) considering the SL context.

Design/methodology/approach

The mixed method was used for the research choice by selecting a questionnaire survey and expert interviews. Completed questionnaires (n = 78) were analysed using statistical techniques. The expert interviews with six industry practitioners were piloted to increase the validity and credibility of survey findings through a triangulation process where the collected data was analysed through content analysis.

Findings

The findings confirm that JV parties should first seek collaborative solutions in a conflict and seek legal redress only when those efforts are unsuccessful. Collaborating and compromising were recommended as the most appropriate tactics if an informal approach to conflict management was chosen. Alternative dispute resolution and litigation were identified as formal conflict management strategies.

Originality/value

This study, to the best of the authors’ knowledge, will be the first of its kind in SL, which will lead to a better understanding of conflict management in IJCVs and will encourage other researchers to extend this study through further work.

Abstract

Purpose

This paper investigates the impact of microfinance on poverty gap which is the shortfall in income or consumption expenditures below $1.90, $3.20 and $5.50 per day. The paper’s primary goal is to investigate how microloans have impacted the severity of poverty and influenced the cost of poverty eradication in Latin America, empirically evaluate these effects and offer appropriate policy recommendations.

Design/methodology/approach

This paper used panel data for 13 Latin American countries from world bank spanning the period 2001–2019 and Fully Modified Ordinary Least Squares model for heterogeneous cointegrated panels. This study used Gross Loan Portfolio per active borrowers, gross domestic product per capita, Gini index, Inflation and Unemployment rate as independent variables and poverty gaps as dependent variables.

Findings

Poverty gaps narrow as the loan per borrower increases, and the degree of effect differs with the poverty line, with the magnitude increasing as the poverty line falls, underscoring microloans as an effective tool in closing poverty gaps and lowering the cost of poverty eradication. Growth of GDP per capita is helpful reducing the poverty gap, especially for the less poor of the poor. Inflation and unemployment have no to little impact on the severe poverty gaps, but they start to matter when the poverty line is $5.5 per day. Finally, income distribution inequality widens the poverty gap regardless of the poverty line used.

Originality/value

This study suggests several implications. For example, Latin American nations need to embrace tangible policies that encourage economic growth while reducing inequalities in income distribution to effectively eradicate poverty. More supportive environment is necessary to increase the effectiveness of microfinance operations, particularly for the poorest populations. Microfinance institutions need to set less stringent conditions for loan accessibility and repayment schedules that are commensurate with different levels of poverty. Finally, strengthening microfinance as a strategic policy to gradually close poverty gaps and reduce the cost of poverty eradication.

Abstract

Purpose

This paper aims to study numerically the flow, heat transfer, and entropy generation of aqueous copper oxide-silver hybrid nanofluid over a down-pointing rotating vertical cone, with linear surface temperature (LST) and linear surface heat flux (LSHF), in the presence of a cross-magnetic field. In industrial applications, such as oil and gas plants, food industries, steel factories and nuclear packages, the real bodies may contain nonorthogonal walls and variable cross-section three-dimensional forms which this issue can clarify the importance of selective geometry in the present research.

Design/methodology/approach

The mass-based scheme is accomplished for the simulation, and the entropy generation and Bejan number will be analyzed in conjunction with the aforementioned model. It has been hypothesized that two types of boundary conditions (LST and LSHF) as well as five nanoparticle shapes (sphere, brick, cylinder, platelet and disk) present a collection of crucial results. The overseeing PDEs are changed over completely to the dimensionless ODEs, and these are solved by Runge–Kutta–Fehlberg approach combined with a shooting methodology for certain values of physical parameters.

Findings

Subsequent to the fantastic compromise of the computational outcomes with past reports, the outcomes are introduced to conduct the investigation of the hydrodynamics/thermal boundary layers, the skin friction and the Nusselt number, as well as entropy generation and Bejan number. A state of hybrid nanofluid, which exhibits a remarkable increase in heat transfer in comparison to the states of mono-nanofluid and regular fluid, has been found to have the highest Nusselt number; however, the skin friction values should always be taken into account and managed. The entropy generation improves with the mass of the second nanoparticle (silver), while the opposite pattern is exhibited for the Bejan number. Furthermore, the lowest value of entropy generation number belongs to the cylindrical shape of nanoparticles in the LST case. In final, a significant accomplishment of the current study is the accurate output of the mass-based scheme for an entropy analysis problem.

Originality/value

To the best of the authors’ knowledge, for the first time, in this study, a new development of natural convective flow of a hybrid nanofluid about the warmed (LST and LSHF) and down-pointing rotating vertical cone by the mass-based algorithm has been presented. The applied methodology considers the masses of base fluid (water) and nanoparticles (Ag and CuO) as an alternative to the first and second nanoparticles volume fraction. Indeed, the combination use of the Tiwari–Das nanofluid model and the mass-based hybridity algorithm for the entropy generation analysis can be the main novelty of this work.
