Abstract

Purpose

In this paper, the authors aim to examine and comparatively evaluate a recently-developed metaheuristic called crystal structure algorithm (CryStAl) – which is inspired by the symmetries in the internal structure of crystalline solids – in solving engineering mechanics and design problems.

Design/methodology/approach

A total number of 20 benchmark mathematical functions are employed as test functions to evaluate the overall performance of the proposed method in handling various functions. Moreover, different classical and modern metaheuristic algorithms are selected from the optimization literature for a comparative evaluation of the performance of the proposed approach. Furthermore, five well-known mechanical design examples are utilized to examine the capability of the proposed method in dealing with challenging optimization problems.

Findings

The results of this study indicated that, in most cases, CryStAl produced more accurate outputs when compared to the other metaheuristics examined as competitors.

Research limitations/implications

This paper can provide motivation and justification for the application of CryStAl to solve more complex problems in engineering design and mechanics, as well as in other branches of engineering.

Originality/value

CryStAl is one of the newest metaheuristic algorithms, the mathematical details of which were recently introduced and published. This is the first time that this algorithm is applied to solving engineering mechanics and design problems.

Abstract

Purpose

This paper aims to enumerate the factors influencing the process of decision-making, those which are mostly related to personality affected by cultures and sub-cultures dominating the individual’s life, such as possessing internal and external control agents, tolerating or avoiding ambiguities and its comparison with a belief in fatalism or free will and the effect of these beliefs and traits on the personality.

Design/methodology/approach

This paper demonstrates that these beliefs would result in the formation of different personal characteristics; for instance, active and passive individuals and those who are keen to discover problems to solve them and change the existing state of affairs to the desired ones. Some individuals can make decisions and some cannot.

Findings

The researcher has tried to make a comparative study and address the genuine Islamic culture as manifested in the Quran, Prophet’s Tradition and Shiite way of life. In this relation, the case studies are the Battle of Uhud and the Quranic verses related to the research to demonstrate that a Muslim manager, by dismissing fatalism while trusting in God’s blessing, could be distinguished from others.

Originality/value

This study adds to our knowledge that managers can make sound decisions by relying on their Shiite culture, self-confidence, rational thinking, consulting the wise people and above all trusting in God.

Abstract

Purpose

An emerging technology in the primary stages of its life cycle is the blockchain. This research paper aims to evaluate the preparedness of hospitals in using blockchain technology in their electronic health record (EHR) systems.

Design/methodology/approach

In the initial stage, 15 criteria relating to preparedness in using blockchain in EHR systems were identified from the literature and divided into five criteria, namely, technological, legal, financial, environmental and organizational. Then, 17 experts from various specialized fields were invited to form expert panels. After validating the criteria identified by the expert panels, the weights of the criteria were determined through the fuzzy best-worst multicriteria decision-making method. Following that, the preparedness of ten selected hospitals in Tehran to use blockchain in their EHR systems was assessed via the weighted aggregated sum product assessment method. Finally, using sensitivity analysis and examining different scenarios, the robustness of the results of the proposed approach was validated.

Findings

According to expert judgments, the legal criterion (32%) was deemed the most important factor in the preparedness to use blockchain in EHR systems followed by technological (28%), financial (17%), organizational (13%) and environmental (9%) criteria. A sensitivity analysis showed that the proposed approach offers good strength and robustness in evaluating the selected hospitals.

Originality/value

This study can be useful in developing knowledge in the field of technology management for evaluating blockchain implementation in the health-care industry using a novel, coherent and robust approach. In addition, the proposed approach provides comprehensive insight for decision-makers on assessing preparedness in deploying blockchain technology in EHR systems.

Abstract

Purpose

Solely focusing on economic development and financial issues have led to insufficient attention to society and the environment, which has increased the injustice in this area. Accounting can aid to compensate for this harm and improve environmental issues. That is why social and environmental accounting (SEA) is rapidly growing and evolving. However, it has not been fully implemented yet. May be one cause for this issue is the lack of identifying the factors that influence SEA implementation in all dimensions. The purpose of this paper seeks to identify these factors.

Design/methodology/approach

Based on the existing theoretical foundations and expert opinions, the factors influencing SEA implementation were divided into seven categories, namely, accounting requirements, environmental justice, environmental responsibility, legal requirements, organizational factors, pollution control and business issues. Interpretative structural modeling and MICMAC techniques were applied to examine the relationships between these categories and model design.

Findings

The results revealed that the legal requirement dimension is one of the effective factors and which has been identified as the cause. However, the rest of the dimensions are influenced by legal requirements. As a result, as the legal requirements are considered as the foundation of establishing the model, this factor must be seriously considered for the effective implementation of the SEA.

Social implications

As the environment is not a unique environment and it has given the pivotal role of the environment in the sustainable development of communities, this leads to an increased demand for improved environmental quality. As a result, public expectations of the accounting profession to increase SEA have increased. In this paper, using the opinions of 12 environmental accounting professionals, a model for Implementation of SEA was designed to avoid social and environmental costs and damages.

Originality/value

Considering that identified factors are of great importance in the implementation of SEA, it seems that using a comprehensive framework that includes all the factors, can have a great impact on how to improve and enhance SEA. This study is the first to provide comprehensive model for SEA implementation.

The present study aims to investigate the reasons for the gap between academic education and the required skills of the labor market in Iran.

Abstract

Purpose

The present study aims to investigate the reasons for the gap between academic education and the required skills of the labor market in Iran.

Design/methodology/approach

For this purpose, the authors adopted a thematic analysis method. The participants in the study were connoisseurs from universities and research institutes in Iran, who were selected with purposeful sampling methods of snowball type. To collect the data, the authors used a semi-structured interview and performed a thematic analysis for data analysis.

Findings

The findings showed that the views and perceptions of the connoisseurs participating in the study about the reasons for the gap between academic education and the skills required in the labor market in Iran can be classified into four main themes including lack of attention to labor market needs in the academic curricula, lack of attention to practical and entrepreneurial skills in the academic curricula, the weak link between universities and industry and society, and shortage of academic resources and equipment in some academic disciplines.

Originality/value

The present study had three implications. First, the human capital theory, the social closure theory, the positional conflict theory and the labor market segmentation theory are more compatible with the labor market of Iranian graduates, compared to other theories of the labor market. Second, the lack of coordination between academic education and the required skills in the labor market has weakened the Iranian economy. Third, the absence of practical and entrepreneurial skills in academic graduates has led to increased unemployment in Iranian society.

Abstract

Purpose

Communication apprehension (CA) is the fear or anxiety about communicating. In addition, self-perceived communication competence (SPCC) refers to the learners' perception of their competence. CA hampers individuals' ability to communicate effectively in various communication contexts, which has an impact on their employability. Confident communicators with effective communication skills are important issues for graduation as well as desirable attributes for recruiting agencies. Given that employers value graduates who can communicate effectively in the workplace without any apprehension, this study was designed to determine the levels of CA and SPCC among final-year non-English major undergraduate students in Saudi Arabia and the extent to which SPCC could affect their CA when speaking in English with implications for their employability as the next generation of workers.

Design/methodology/approach

Two survey questionnaires were administered to 70 non-English major undergraduate students in their final year employing probability random sampling to measure their CA level and to assess their SPCC in different English as foreign language (EFL) contexts. Pearson's correlation and linear regression analysis were used to investigate the relationship between CA and SPCC. Data analysis was performed using descriptive statistics in SPSS 21.

Findings

The findings indicated a medium level of SPCC and CA. Moreover, the correlation formula revealed that there was a moderately significant association between learners' SPCC and their CA (r (70) = −0.524, p < 0.01). Through regression analysis, it was found that their SPCC could predict 27% of the variance in their CA. The moderate effect of SPCC on CA implied that students could be prepared to cope and perform in the workplace.

Originality/value

Without communication, the establishment and evolution of the human community are unattainable. This aspect is more evident and crucial in the list of graduate objectives and needed outcomes for future career endeavors. The findings encourage instructors and course designers to provide many learning opportunities in pleasurable learning environments to raise students' perceptions of their competence, in turn enhancing their confidence to speak in English and ensuring a smooth transition from academia to the workplace. Based on the findings, several suggestions for future studies in the EFL context are presented.

Abstract

Purpose

The purpose of this paper is to report the effect of radiation on flow of a magneto‐micropolar fluid past a continuously moving plate with suction and blowing.

Design/methodology/approach

The governing equations are transformed into dimensionless nonlinear ordinary differential equations by similarity transformation. Analytical technique, namely the homotopy perturbation method (HPM) combining with Padé approximants and finite difference method, are used to solve dimensionless non‐linear ordinary differential equations. The skin friction coefficient and local Nusselt numbers are also calculated. Beside this, the comparison of the analytical solution with numerical solution is illustrated by the graphs for different values of dimensionless pertinent parameters.

Findings

The authors have studied laminar magneto‐micropolar flow in the presence of radiation by using HPM‐Padé and finite difference methods. Results obtained by HPM‐Padé are in excellent agreement with the results of numerical solution.

Originality/value

The HPM‐Padé is used in a direct way without using linearization, discritization or restrictive assumption. The authors have attempted to show the capabilities and wide‐range applications of the HPM‐Padé in comparison with the finite difference solution of magneto‐micropolar flow in the presence of radiation problem.

Abstract

Purpose

This study aims to identify the main factors affecting export competitiveness and its barriers, focusing on the minerals industry so that a scale is achieved for measuring export competitiveness in this industry.

Design/methodology/approach

The research was conducted with a mixed method approach in the minerals industry. Among the active companies involved in this industry, 34 export companies and export management companies were selected and evaluated. In the qualitative phase, 18 experts and managers of the industry were interviewed to identify the factors affecting the export competitiveness of these companies and the barriers ahead of them. In the quantitative phase, a questionnaire was distributed among 412 managers and experts in this industry to categorize the identified factors and to measure the relationships among them. For data analysis in the qualitative phase, theme analysis was used. For the quantitative phase, factor analysis and structural equation modeling were adopted.

Findings

In addition to identifying the main components affecting the competitiveness of companies in exporting minerals as well as the main barriers ahead of them, the findings of the current research categorized these components using factor analysis. These components were categorized into factors, such as manufacturing factors, demand conditions, related and supporting industries, structural factors, competitive strategy and governmental supports. Afterward, their impacts on export competitiveness were measured and supported.

Originality/value

Although some studies have been conducted to examine the competitiveness in different industries, no research has been found that has examined and identified the main factors affecting export competitiveness and their impacts in the minerals industry with a mixed quantitative and qualitative approach. The findings of this research may help managers and policymakers, at the industrial and national levels, to reach a scale for assessing the export companies involved in this industry by identifying the most essential factors of export competitiveness of minerals. Furthermore, the findings of this research can act as a model for future researchers to develop a scale for export competitiveness in other industries.
