The Grey System Theory (GST) is an emerging area of research within artificial intelligence. Since its founding in 1982, it has seen a lot of multidisciplinary applications. In just a short period, it has garnered some considerable strengths. Based on the 1987–2021 data collected from the Web of Science (WoS), the current study reports the advancement of the GST.

Research papers utilizing the GST in the fields of economics and education were retrieved from the Web of Science (WoS) platform using a set of predetermined keywords. In the final stage of the process, the papers that underwent analysis were manually chosen, with selection criteria based on the information presented in the titles and abstracts.

The study identifies prominent authors, institutions, publications and journals closely associated with the subject. In terms of authors, two major clusters are identified around Liu SF and Wang ZX, while the institution with the highest number of publications is Nanjing University of Aeronautics and Astronautics. Moreover, significant keywords, trends and research directions have been extracted and analyzed. Additionally, the study highlights the regions where the theory holds substantial influence.

The study is subject to certain limitations stemming from factors such as the language employed in the chosen literature, the papers included within the Web of Science (WoS) database, the designation of works categorized as “articles” in the database, the specific selection of keywords and keyword combinations, and the meticulous manual process employed for paper selection. While the manual selection process itself is not inherently limiting, it demands a greater investment of time and meticulous attention, contributing to the overall limitations of the study.

The significance of the study extends not only to scholars and practitioners but also to readers who observe the development of emerging scientific disciplines.

The analysis of trends revealed a growing emphasis on the application of GST in diverse domains, including supply chain management, manufacturing and economic development. Notably, the emergence of COVID-19 as a new research focal point among GST scholars is evident. The heightened interest in COVID-19 can be attributed to its global impact across various academic disciplines. However, it is improbable that this interest will persist in the long term, as the pandemic is gradually brought under control.

In comparison to other industries, the construction industry is one of the most dangerous industries. Behavior-based safety (BBS) is a common and useful technique for risk indicator processing. Almost all studies are based on the BBS checklist, but very few of them focus on the increasing dangers faced by construction workers and the important factors that lead to accidents. This research represents a risk spatiotemporal analysis and visual tracking approach based on BBS and Building Information Modeling (BIM).

After the literature review, a BBS checklist was developed. Then a survey was conducted based on the BBS checklist and the temporal evolution of risks has been completed. After that, managing the risk with the automatic rule checking (ARC) system using BIM was conducted simultaneously to develop a framework by conducting a case study.

Based on the grey clustering analysis, this work provides a temporal evolution analysis approach for dynamic analyzing BBS risk. According to the grey relational analysis (GRA) data, the main key factor of risk was the missing guardrail/handrail system. After that, a case study was performed and the system automatically warn in the preconstruction phase that the barrier is missing as the system benefits.

A systematic framework has been provided for risk analysis through which high health and safety performance outcomes can be achieved on construction projects. This study will assist design engineers in addressing the potential danger to employees during the preconstruction stage and monitoring dynamic changes in risk on any construction site.

Traditional multivariable grey prediction models define the background-value coefficients of the dependent and independent variables uniformly, ignoring the differences between their physical properties, which in turn affects the stability and reliability of the model performance.

A novel multivariable grey prediction model is constructed with different background-value coefficients of the dependent and independent variables, and a one-to-one correspondence between the variables and the background-value coefficients to improve the smoothing effect of the background-value coefficients on the sequences. Furthermore, the fractional order accumulating operator is introduced to the new model weaken the randomness of the raw sequence. The particle swarm optimization (PSO) algorithm is used to optimize the background-value coefficients and the order of the model to improve model performance.

The new model structure has good variability and compatibility, which can achieve compatibility with current mainstream grey prediction models. The performance of the new model is compared and analyzed with three typical cases, and the results show that the new model outperforms the other two similar grey prediction models.

This study has positive implications for enriching the method system of multivariable grey prediction model.

This study aims to investigate the morphing concepts able to manipulate the dynamics of the downstream unsteadiness in the separated shear layers and, in the wake, be able to modify the upstream shock–boundary layer interaction (SBLI) around an A320 morphing prototype to control these instabilities, with emphasis to the attenuation or even suppression of the transonic buffet. The modification of the aerodynamic performances according to a large parametric study carried out at Reynolds number of 4.5 × 10⁶, Mach number of 0.78 and various angles of attack in the range of (0, 2.4)° according to two morphing concepts (travelling waves and trailing edge vibration) are discussed, and the final benefits in aerodynamic performance increase are evaluated.

This article examines through high fidelity (Hi-Fi) numerical simulation the effects of the trailing edge (TE) actuation and of travelling waves along a specific area of the suction side starting from practically the most downstream position of the shock wave motion according to the buffet and extending up to nearly the TE. The present paper studies through spectral analysis the coherent structures development in the near wake and the comparison of the aerodynamic forces to the non-actuated case. Thus, the physical mechanisms of the morphing leading to the increase of the lift-to-drag ratio and the drag and noise sources reduction are identified.

This study investigates the influence of shear-layer and near-wake vortices on the SBLI around an A320 aerofoil and attenuation of the related instabilities thanks to novel morphing: travelling waves generated along the suction side and trailing-edge vibration. A drag reduction of 14% and a lift-to-drag increase in the order of 8% are obtained. The morphing has shown a lift increase in the range of (1.8, 2.5)% for angle of attack of 1.8° and 2.4°, where a significant lift increase of 7.7% is obtained for the angle of incidence of 0° with a drag reduction of 3.66% yielding an aerodynamic efficiency of 11.8%.

This paper presents results of morphing A320 aerofoil, with a chord of 70cm and subjected to two actuation kinds, original in the state of the art at M = 0.78 and Re = 4.5 million. These Hi-Fi simulations are rather rare; a majority of existing ones concern smaller dimensions. This study showed for the first time a modified buffet mode, displaying periodic high-lift “plateaus” interspersed by shorter lift-decrease intervals. Through trailing-edge vibration, this pattern is modified towards a sinusoidal-like buffet, with a considerable amplitude decrease. Lock-in of buffet frequency to the actuation is obtained, leading to this amplitude reduction and a drastic aerodynamic performance increase.

This study aims to understand the relationship between entrepreneurial competencies (self-efficacy and social capital) and sustainable entrepreneurship and its incidence through entrepreneurial motivations (opportunity and necessity entrepreneurship).

The authors adopt a quantitative approach and use ordinary least squares regressions and bootstrapping analysis to test the hypotheses about the relationship between entrepreneurial competencies and sustainable entrepreneurship mediated by entrepreneurial motivations using a cross-sectional sample of 2,356 nascent entrepreneurs from the Global Entrepreneurship Monitor 2021–2022 report.

Evidence suggests that sustainable entrepreneurship is positively influenced by both opportunity- and necessity-driven entrepreneurship. Additionally, the results show that both entrepreneurial motivations positively mediate the relationship between self-efficacy and sustainable entrepreneurship.

The approach departs from the traditional unidimensional perspective on entrepreneurial motivations, recognizing that an entrepreneur can simultaneously embody varying degrees of both motivations. By integrating the study of entrepreneurial competencies and motivations into sustainable entrepreneurship, we can gain a holistic understanding of the dynamics at play.

El objetivo de este estudio es comprender la relación entre las competencias emprendedoras (autoeficacia y capital social) con el emprendimiento sostenible y su incidencia a través de las motivaciones emprendedoras (emprendimiento por oportunidad y por necesidad).

Adoptamos un enfoque cuantitativo y utilizamos regresiones de mínimos cuadrados ordinarios (MCO) y análisis de bootstrapping para probar nuestras hipótesis sobre la relación entre las competencias emprendedoras y el emprendimiento sostenible mediado por las motivaciones emprendedoras utilizando una muestra transversal de 2.356 emprendedores nacientes del informe Global Entrepreneurship Monitor (GEM) 2021–2022.

La evidencia sugiere que tanto el emprendimiento de oportunidad como el de necesidad tienen un impacto positivo en el emprendimiento sostenible. Además, encontramos que ambas motivaciones emprendedoras median positivamente la relación entre la autoeficacia y el emprendimiento sostenible.

Nuestro enfoque se aleja de la tradicional perspectiva unidimensional de las motivaciones emprendedoras, reconociendo que un emprendedor puede encarnar simultáneamente diversos grados de ambas motivaciones. Al integrar el estudio de las competencias y motivaciones emprendedoras en el emprendimiento sostenible, obtenemos una comprensión holística de la dinámica en juego.

Este artigo tem como objetivo compreender a relação entre as competências empreendedoras (autoeficácia e capital social), e o empreendedorismo sustentável e sua incidência por meio de motivações empreendedoras (empreendedorismo de oportunidade e necessidade).

Adotamos uma abordagem quantitativa e usamos regressões de mínimos quadrados ordinários (OLS) e análise de bootstrapping para testar nossas hipóteses sobre a relação entre competências empresariais e empreendedorismo sustentável mediada por motivações empresariais usando uma amostra transversal de 2.356 empreendedores nascentes do relatório Global Entrepreneurship Monitor (GEM) 2021–2022.

As evidências sugerem que o empreendedorismo sustentável é influenciado positivamente pelo empreendedorismo orientado pela oportunidade e pela necessidade. Além disso, os resultados mostram que ambas as motivações empresariais mediam positivamente a relação entre a autoeficácia e o empreendedorismo sustentável.

Nossa abordagem se afasta da perspectiva unidimensional tradicional sobre as motivações empresariais, reconhecendo que um empreendedor pode incorporar simultaneamente vários graus de ambos os ases motivações. Ao integrar o estudo das competências e motivações empresariais ao empreendedorismo sustentável, obtemos uma compreensão holística da dinâmica em jogo.

Circular economy (CE) is receiving increasing worldwide attention as a manner to overcome the challenges linked to current trends of unsustainable energy and resource consumption. This paper aims to fill this gap and analyze the adherence to sustainable, access-based and collaborative consumption practices by exploring the role of CE awareness, specifically in the context of Porto, the second-largest city of Portugal.

The methodology of choice is quantitative, based on partial least square-based structural equation modeling.

The result shows that there is an influence of CE awareness on subsequent sustainable consumption models.

Present research contributes to the theory on CE awareness and sustainable consumption. It proposes a model that could be applied in other countries. As this research is developed within the city of Porto, it may limit generalizations of obtained results.

As CE practices are embodied into national and local policies, this research contributes to understanding local contexts of CE practices dissemination, providing practical suggestions for businesses and policymakers aiming the transition to the CE.

An original approach to measuring the awareness of CE economy is proposed, that is analyzed not only from the familiarity perspective but in six dimensions of its construction: familiarity, importance, perception or interpretation, advantages, social impact and barriers in this process. Further, the conceptual model of the impact that these dimensions have on the adoption of sustainable consumption models (purchase of sustainable products, access-based and collaborative consumption) is proposed.

This study reviews and discusses the accounting literature that analyzes the role of auditors and enforcers in the context of fraud.

This literature review includes both qualitative and quantitative studies, based on the idea that the findings from different research paradigms can shed light on the complex interactions between different financial reporting controls. The authors use a mixed-methods research synthesis and select 64 accounting journal articles to analyze the main proxies for fraud, the stages of the fraud process under investigation and the roles played by auditors and enforcers.

The study highlights heterogeneity with respect to the terms and concepts used to capture the fraud phenomenon, a fragmentation in terms of the measures used in quantitative studies and a low level of detail in the fraud analysis. The review also shows a limited number of case studies and a lack of focus on the interaction and interplay between enforcers and auditors.

This study outlines directions for future accounting research on fraud.

The analysis underscores the need for the academic community, policymakers and practitioners to work together to prevent the destructive economic and social consequences of fraud in an increasingly complex and interconnected environment.

This study differs from previous literature reviews that focus on a single monitoring mechanism or deal with fraud in a broadly manner by discussing how the accounting literature addresses the roles and the complex interplay between enforcers and auditors in the context of accounting fraud.

The study aims to highlight the barriers faced by the entrepreneurs toward achieving sustainability in business and innovation cultivation by offering solutions for academicians, practitioners and policymakers. The study uses the resource-based view (RBV) theory to discuss how an organization’s resources and capabilities influence the competitive ambience and barriers faced by entrepreneurs.

The present research uses grey-causal modelling (GSC) to analyse the barriers against successful entrepreneurship.

The research focuses on the usefulness of dynamic capabilities, managing and cooperating resources in the entrepreneurship setting. The paper highlights the importance of resource gathering and nurturing as a method to combat scarcity. This research further identifies that financial limitations, regulatory obstacles, challenges to sourcing qualified labour, poor infrastructure and technology, limited mentorship opportunities, lack of scalability, low initial cost barriers in product development and risk-averse attitudes are the major factors hindering entrepreneurs from obtaining sustainable business and innovation.

The contribution of this research to the literature is that it assesses RBV theory within the realm of entrepreneurship, providing a different perspective on resources and capabilities as well as the challenges faced by entrepreneurs. The systematic approach to the analysis and prioritization of various barriers is innovative, and it adds knowledge in this area.

The purpose of this paper is to examine the impact of social movements engendered by the Arab Spring crisis on the relationship between corporate social responsibility disclosure (CSRD) and corporate governance attributes, particularly board composition, considering the importance of governance after the Arab Spring event.

Content analysis was used to examine the extent and nature of CSRD in annual reports of Jordanian companies listed on the Amman Stock Exchange covering the period 2009–2016. A dynamic regression model using panel data is then undertaken for a sample of 114 listed companies over the period to analyse the potential impact of board composition on the level of CSRD.

The results reveal that there was a significant increase in the level of CSRD post-the Arab Spring crisis; and that governance appears to be a key driver. Specifically, board age, directors educated in business and/or accounting-related fields and foreign members are found to have a significant positive relationship with CSRD.

Looking at the Arab region pre- and after the Arab Spring helps to complete the global picture of how company governance can lead to improved CSR performance. Specifically, this region has been behind in developing rules and codes that include CSR. The results show that having a diverse board, with directors with expertise specific to the context, increases the effectiveness of stakeholder management through CSRD. The results, therefore, offer valuable insights for companies, policymakers and for the development of regulations.

The dynamics of work have increased the importance of work conditions and job demand in the corporate environment. This has exposed the high predominance of work overload among employees and managers in social organisations. This study aims to investigate the contemporary determinants of workaholism (organisational culture, financial well-being and career development) and quality of work-life (QWL) in Nigeria’s information technology (IT) sector.

To synthesise an understanding of factors that are responsible for workaholic behaviour among employees in the IT industry, this study used a cross-sectional research design to investigate the phenomenon that accounts for such hysteric conditions. This study administered an inventory battery of scales to obtain data from the study population on a random sampling technique to measure the established constructs responsible for workaholism and QWL. This study surveyed 644 samples of IT professionals in Nigeria and used structural equation modelling and artificial neural networks to examine the data obtained from the IT professionals.

The outcome of this study was significant as proposed. This study demonstrated that compulsive work approach adversely affects employee QWL in Nigeria’s IT industry. Also, excessive work adversely affects employee QWL in Nigeria’s IT industry. This study further discovered that organisational culture and management pressure significantly affect the QWL in the Nigerian IT industry. The results of this study showed that financial well-being significantly affects the QWL in the Nigerian IT industry. Lastly, it established that career development significantly affects the QWL in the Nigerian IT industry. This study concluded that if working round the clock is not completely removed from Nigeria’s IT cultural system, the industry will not be a safe environment and will not attract employees anymore. It has enabled many Nigerian workforces to quit working in Nigeria and migrate to international organisations.

This study has shown a meaningful dimension by discovering that workaholism is inherently in the cultural values and DNA of Nigerian IT institutions and not work addiction in itself for the employees. The novelty of this research has indicated that workaholism has not been documented much in the Nigerian IT sector.
