The control of ventilation systems is often performed by automatic algorithms which often do not consider the future evolution of the system in its control politics. Digital twins allow system forecasting for a more sophisticated control. This paper explores a novel methodology to create a Machine Learning (ML) model for the predictive control of a ventilation system combining Computational Fluid Dynamics (CFD) with Artificial Intelligence (AI). This predictive model was created to forecast the temperature and humidity evolution of a ventilated room to be implemented in a digital twin for better unsupervised control strategies. To replicate the full range of annual conditions, a series of CFD simulations were configured and executed based on seasonal data collected by sensors positioned inside and outside the room. These simulations generated a dataset used to develop the predictive model, which was based on a Deep Neural Network (DNN) with fully connected layers. The model’s performance was evaluated, yielding final average absolute errors of 0.34 degrees Kelvin for temperature and 2.2 percentage points for relative humidity. The presented results highlight the potential of this methodology to create AI-driven digital twins for the control of room ventilation. Full article

With the continuous development of today’s economy and the growing interest in green technological innovation, this study investigates the impact of executive political connection heterogeneity (EPCH) on corporate green technological innovation (CGTI) in Chinese listed companies. Specifically, it distinguishes between ascribed and achieved political connections, examining their influence on incremental and radical CGTI. This study employs a quantitative research design, utilizing a sample of Chinese A-share listed companies from 2007 to 2022. Data are sourced from the China Securities Market & Accounting Research (CSMAR) database and the China National Research Data Service (CNRDS) database. The study analysis applies fixed-effect regression models to test the relationships between political connection heterogeneity and innovation outcomes. The findings reveal that ascribed political connections promote incremental innovation, while achieved political connections drive radical innovation. Moreover, strong GEO weakens the effect of ascribed political ties on incremental CGTI while enhancing the effect of achieved political ties on radical CGTI. These results contribute to the understanding of how political ties influence corporate innovation strategies and provide insights into the role of dynamic capabilities in green technological advancements.

Social cinema is a cinematographic expression used to denounce current and historical problems, as well as to identify social limits and promote the transformation of society itself. To this end, works included in social cinema depict aspects of reality to critically influence it. The objective of this study is to examine the evolution of social cinema, as well as its scientific, economic and political bases and its main consequences for the general population. Method: This study was conducted by the application of the technique of qualitative research thematic analysis as a procedure in the process of the execution of the scientific task, related to a historical trend study of the research object. The search was carried out in the databases of IMDB and the Culture Ministry of Spain. The end of the dictatorship and the beginning of democracy (1975) was placed as the historical cutting point in the analysis. Various psychosocial variables were used as categories of analysis, including poverty, work, substance use, crime, urban and rural contexts, violence, etc. Results: Spanish social cinema has evolved since its origins in the 1950s as a reflection of Spanish society. These developments, including both progressions and regressions, have been connected with social, political and economic factors. Conclusions: While the shape of Spanish social cinema has changed over time, its themes have remained similar since the origin: poverty, work and hopelessness. The evolution has not been continuous, as it has fluctuated in response to the claims and requests from the context. The Spanish social cinema has reflected topics and images from Spanish society, even when the sociopolitical context avoided them. Finally, the legitimacy of Spanish social cinema is based on its cultural strength and social/political commitment. Full article

Seaplane operations connect remote areas, promote tourism, and provide unique transportation solutions. After many years of preparations, commercial seaplane operations on a network of 100 water airports and 200 waterways in Greece are about to commence. The network can serve the needs of 1.6 million permanent residents of the Greek islands, the inhabitants of the mainland, and over 35 million annual tourists. This paper aims to conduct a PESTLE (Political, Economic, Social, Technological, Legal, and Environmental) analysis to identify the factors that have delayed operations and those that will affect the success of future operations. As such, 26 factors are examined. It was found that the Greek debt crisis and the COVID-19 pandemic were impediments to operations. The potential of using electric seaplanes is discussed. Recent developments in using drone inspection capabilities for aviation safety are examined. Management strategies for the Etesian winds and other environmental issues are presented. Overall, seaplane operations have enormous potential, while the Greek economic recovery provides favorable conditions for completing the project. The critical issue determining success is executing a multi-faceted business model to ensure seaplane operations’ financial viability. The network can act in synergy with other modes of transportation to help achieve social cohesion, improve tourism services, and foster economic development. Full article

Accurate disclosure and proactive engagement in ESG practices are essential for achieving high-quality economic development, particularly as China addresses significant challenges during its reform journey. The Classified Reform of State-Owned Enterprises (CRSOE) is a strategic initiative by the Chinese government aimed at fostering this development. Our study leverages the implementation of the CRSOE as an exogenous shock, employing the difference-in-differences approach to assess the policy’s governance impact on ESG decoupling from the perspective of ownership heterogeneity. The policy was found to alleviate ESG decoupling, particularly pronounced among SOEs with special functions. The governance effect is achieved by reducing the aspiration–performance gap. Specifically, the policy effectively narrows the disparity between a company’s actual performance and the expected performance based on the industry average, thereby mitigating ESG decoupling. However, the policy’s impact can be weakened by factors such as political connections among executives and media attention. Furthermore, the CRSOE effectively addresses greenwashing practices within ESG decoupling, with a particularly strong effect on SOEs that fail to disclose ESG information in alignment with Global Reporting Initiative (GRI) standards. These findings highlight the importance of understanding the broader implications and underlying mechanisms of the policy. Therefore, building on the assessment of how the CRSOE policy impacts ESG decoupling, we also examine the mechanisms through which this policy operates and how its effectiveness varies under different conditions of heterogeneity. By extending the application of principal-agent theory and performance feedback theory, our research suggests that policymakers should prioritize market-driven reforms for fully competitive SOEs and promote a stronger emphasis on non-financial goals. Additionally, it is essential to mitigate the undue influence of political promotions on the management of all SOEs. Full article

This study examines the impact of military cultural atmosphere on corporate innovation risk-taking within the unique institutional context of China. Leveraging an unbalanced panel dataset of 3506 Chinese A-share listed companies, comprising 15,381 observations from 2010 to 2022, this empirical analysis captures dynamic firm-level changes over time. Using ordinary least squares (OLS) regression to assess the effects of military cultural atmosphere and two-stage least squares (2SLS) to address potential endogeneity concerns, this study ensures robust results. The findings reveal that military cultural atmosphere, characterized by discipline, hierarchy, and collective responsibility, significantly enhances firms’ propensity for innovation risk-taking. Additionally, political connections emerge as a key mediating factor in this relationship, while perceived power within the organization moderates the mediation effect, exhibiting a negative moderation. These results underscore the critical role of military backgrounds among senior executives in shaping corporate culture and strategic decision-making, particularly in China’s policy-driven market environment. This study offers valuable insights for fostering long-term corporate resilience and strategic innovation, while also contributing to a deeper understanding of the interaction between corporate culture and innovation across different institutional settings.

Aiming at the research limitation concerning the insufficient exploration of executive social connections in enterprise digital transformation, our research objective is to investigate the influence of executive social connections, namely political and business connections, on enterprise digital transformation. Furthermore, it assesses the moderating effects of regional digital economy development on these relationships. An empirical analysis, encompassing 5407 observations from 868 listed firms between 2012 and 2021 in China, demonstrates that executive political and business connections significantly contribute to enterprise digital transformation both individually and synergistically. Specifically, political connections are found to be more relevant to enhancing enterprise digital transformation in regions with higher levels of digital economy development, while business connections exhibit a stronger correlation in regions with lower levels of digital economy development. Additionally, it is revealed that the synergistic effect of political and business connections is more relevant to enterprise digital transformation in regions with lower levels of digital economy development.

In the context of the digital economy, the external connection of executives provides enterprises with a good idea to amplify their potential for digital transformation with the help of external forces. Therefore, we conduct a theoretical exploration and an empirical analysis of the relationship between executive connections and enterprise digital transformation. As the research sample, we use the A-share manufacturing companies listed in China from 2012 to 2021. According to sufficient verifications, we discover that executive connections can effectively support digital transformation. From the perspective of each subdivision dimension, executive business connections, executive technical connections, and executive financial connections can significantly promote digital transformation, among which executive technical connections have the greatest favorable impact. However, the impact of executive political connections on digital transformation is not obvious. Additionally, executive connections primarily foster enterprise digital transformation by reducing enterprise asset specificity. The results of the boundary mechanism test demonstrate that the external environmental dynamics and the internal dynamic capabilities reinforce the positive effect of executive connections on digital transformation. These findings contribute to a deeper understanding of the role of executive connections in digital transformation and provide practical guidance for firms to accelerate digital transformation.

As the grassroots-party organizations of the Communist Party of China (CPC) are increasingly involved in the governance of private-owned enterprises (POEs), whether this new pattern promotes corporate innovation is still a research gap. Therefore, based on the data of 1357 POEs’ party-organization involvements and their patent applications from 2003 to 2017, this paper analyzes the impact of the party-organization involvements on corporate innovation by using the multiple regression model. The results include: (1) party-organization involvements including party organization activities and senior executives’ participation can significantly promote innovation, especially after 2012; (2) party-organization activities improve innovation by increasing research and development (R&D) investment and reducing operating risk, while the senior executives’ participation only influences on R&D investment; (3) the party-organization involvements have a stronger promotion on non-invention patent applications, especially for the utility-model-patent applications, than invention-patent applications; (4) the promotion is more pronounced for family businesses, technology-intensive and capital-intensive enterprises, as well as those located in the northern, Beijing-Tianjin-Hebei region and Yangtze River delta. After applying PSM sampling and difference-in-differences (DID) analyses, and substituting the dependent variables, the results remain robust. This paper provides Chinese evidence for party construction and corporate innovation, and also provides references about political connection and corporate innovation for other countries to some extent.

In developing distribution networks, the deployment of alternative generation sources is heavily motivated by the growing energy demand, as by environmental and political motives. Consequently, microgrids are implemented to coordinate the operation of these energy generation assets. Microgrids are systems that rely on power conversion technologies based on high-frequency switching devices to generate a stable distribution network. However, disrupting scenarios can occur in deployed systems, causing faults at the sub-component and the system level of microgrids where its identification is an economical and technological challenge. This paradigm can be addressed by having a digital twin of the low-level components to monitor and analyze their response and identify faults to take preventive or corrective actions. Nonetheless, accurate execution of digital twins of low-level components in traditional simulation systems is a difficult task to achieve due to the fast dynamics of the power converter devices, leading to inaccurate results and false identification of system faults. Therefore, this work proposes a fault identification framework for low-level components that includes the combination of Real-Time systems with the Digital Twin concept to guarantee the dynamic consistency of the low-level components. The proposed framework includes an offline trained Self Organized Map Neural Network in a hexagonal topology to identify such faults within a Real-Time system. As a case study, the proposed framework is applied to a three-phase two-level inverter connected to its digital model in a Real-Time simulator for open circuit faults identification. Full article

The difference in wages between executives and employees reflects the class conflict in corporate governance. To investigate the political factors within the practice of corporate governance related to employees, this paper empirically tests the relationship among political connections, ownership and within-firm pay gaps. We take the A-share listed companies on the Shanghai and Shenzhen Stock Exchange as the example, design hypothesis tests and examine the effects of political connections on the pay gap in two distinctive groups of companies, the state-owned enterprises (SOEs) and the non-stated-owned enterprises (non-SOEs). The overall result indicates that political connections increase the average salary of executives and decrease the average salary of employees, thereby expanding the within-firm pay gap. Pay gaps in companies with political connections are 16% higher than companies without political connections. The further test results of distinguishing property rights show that in non-SOEs, political connections increase the executives’ compensation and decrease the average compensation of employees, resulting in an increase of the within-firm pay gap. Similar relationships appear in SOEs but without statistical significance. These findings expand the research on income distribution effects of political connections theoretically, and provide useful insights for SOEs’ reform and income distribution system reform in practice.

Since the empirical evidence on the relationship between corporate social responsibility disclosure (CSRD) and firm productivity is scarce in the context of the banking industry, the study examines whether CSRD leads banks in Bangladesh to higher productivity. Using annual report data of all 30 banks listed on the Dhaka Stock Exchange in Bangladesh from 2011 to 2018, the study applied a data envelopment analysis (DEA) to determine the productivity of the sample banks, and then ordinary least squares (OLS) analysis to examine the impact of CSR on the banks’ productivity. Furthermore, the study utilized two-stage least squares (2SLS) and a generalized method of moments (GMM) to check the robustness of the findings amid the detection of endogeneity issues. The study also used several alternative variables to check and verify the reliability of the study. The findings indicate that the greater a bank’s contribution to CSR, the higher its productivity. However, banks with more debt to assets are less productive. Additionally, the study observed that the impact of CSRD on bank productivity is higher in GRI banks compared to non-GRI banks, non-politically connected banks as opposed to politically connected banks, and conventional banks compared to Islamic banks. The study provides valuable insight into how CSR activities can promote bank productivity, thus motivating the banks to execute a well-thought-out action plan to ensure more CSR contribution. This study is the first ever bank-level evidence that provides insight into how the patterns of CSR activity of publicly traded banks impact their productivity. Full article

Small lakes within social sciences’ conceptualisation are mostly wanting, less anchored and seldom scrutinised in academic literature as opposed to large lakes and natural sciences. Essentially, small lakes, from a social sciences’ perspective, are about people connecting and enhancing through lake governance. Thus, the main argument is that a small lake’s people must accept, broaden and elevate the prospect of lake governance by focusing on and embracing the central concepts of government—the most compulsory and crucial constituent—as well as premier leader—the most pre-eminent and imperative function. Accordingly, lake governance refers to engaging with and intervening in the collective people of a small lake, to undertake economic development, pursue ecological conservation and manage government. Government refers to steering a small lake’s people towards emphasising executive authority and decision-making power, whether through solutions, policies, regulations and/or implementations. The premier leader refers to the person presiding over a small lake’s people in the critical aspects of resoluteness—in establishing and sustaining the rules—and decisiveness—in settling and determining a community’s issues. Overall, as small lakes’ people are political, lake governance is consequential, and a government/premier leader is evidently the most efficacious outcome, whether for addressing problems, choosing decisions or ameliorating society.

Under the background of increasingly severe environmental problems, green innovation has become a key way to realize coordinated development of economy and environment. Therefore, it is of great significance to explore the antecedent factors of green innovation. Based on the upper-echelon theory, this study explores the influence of the academic background of top management teams (TMT) on firm's green innovation outcomes and firm performance in Chinese listed companies. This study also discusses three boundary conditions for TMT's academic experience to promote firm's green innovation. The results show that TMT's academic experience promotes green innovation output. Moreover, TMT's academic experience do not have a uniform effect: strict environmental regulation strengthens the relationship between TMT's academic experience and green innovation output, while political connection and innovation input negatively moderate this relationship. Furthermore, green innovation output does not result in better economic benefits for enterprises with top executives who have academic experience, and this condition is observed more in state-owned enterprises. This study reveals the motivation of green innovation and provides a useful reference for enterprises to implement green innovation strategy more effectively. Full article

Building upon prior literature on the role of executives in tax payments, this study investigates the relationship between a CEO’s political connections and tax avoidance behavior as a typical type of social irresponsibility of a corporation. We propose that CEOs who are well connected to politicians through family, academic, and professional ties tend to adopt riskier strategic choices such as tax avoidance. We employ a multi-faceted method to quantify political connections in a more comprehensive and delicate way. Empirical results from 4,706 firm-year observations in South Korea between 2003 and 2014 provide support for our predictions. In addition, we test competing hypotheses on the moderating role of CEO tenure and find that such a tendency diminishes as the focal CEO stays in the position longer. Full article
