This paper aims to study a parameter tuning method for the active disturbance rejection control (ADRC) to improve the anti-interference ability and position tracking of the performance of the servo system, and to ensure the stability and accuracy of practical applications.

This study proposes a parameter self-tuning method for ADRC based on an improved glowworm swarm optimization algorithm. The algorithm is improved by using sine and cosine local optimization operators and an adaptive mutation strategy. The improved algorithm is then used for parameter tuning of the ADRC to improve the anti-interference ability of the control system and ensure the accuracy of the controller parameters.

The authors designed an optimization model based on MATLAB, selected examples of simulation and experimental research and compared it with the standard glowworm swarm optimization algorithm, particle swarm algorithm and artificial bee colony algorithm. The results show that the response time of using the improved glowworm swarm optimization algorithm to optimize the auto-disturbance rejection control is short; there is no overshoot; the tracking process is relatively stable; the anti-interference ability is strong; and the optimization effect is better.

The innovation of this study is to improve the glowworm swarm optimization algorithm, propose a sine and cosine, local optimization operator, expand the firefly search space and introduce a new adaptive mutation strategy to adaptively adjust the mutation probability based on the fitness value, improve the global search ability of the algorithm and use the improved algorithm to adjust the parameters of the active disturbance rejection controller.

The research mainly aims at the hotspot of inventory management by knowledge mapping and provides a visualization reference in this research field.

First, inventory management journals during 1986 to 2017 were selected as the research object and text formatting in the Web of Science (WOS) database is exported. Then inventory management knowledge mapping is done and clustering keywords are extracted by using CiteSpace and VOSviewer software. Based on co-word analysis, the three special clusters are exported: inventory optimization strategy, inventory pricing and inventory technology. Besides, the clustering structure and time evolution are analysed. Finally, bibliographic item co-occurrence matrix builder (BICOMB) was used to extract the “journal” and “researchers” keywords in the inventory management research fields. Setting three parameters such as the cited half-life, centrality, frequency and keywords for data mining, it can infer the trend keywords of future research.

Results showed that inventory management research has been abundant in literature over the past 30 years and has experienced a change from focusing on inventory optimization strategy to inventory pricing and inventory technology in process. It shows that inventory management research focused on the classic topics and includes economic order quantity, dynamic pricing, design and technology, and the new topics include channel coordination, hierarchical price and simulation.

Based on knowledge mapping, this study is still relatively macro and cannot cover all areas of inventory management. This study only investigated the state of correlational research in WOS and Google Trends and not additional databases.

The current research mainly builds on knowledge mapping for the research hotspot of inventory management and provides visual references for future research in this field.

The purpose of this paper is to evaluate the impact of minority shareholders’ attendance at shareholders meetings on related party transaction (RPT) proposals.

This paper empirically examines the impact of minority shareholders’ attendance in shareholders’ meetings on the voting results of RPT proposals based on the hand-collected voting data of Chinese listed companies.

The empirical result shows a significant positive relationship between the attendance of minority shareholders and the nonagreeable vote rate of RPT proposals. Moreover, this positive relationship is strengthened when the corporate governance is poor, the negative media coverage is high, and the on-site attendance of minority shareholders is high. Conversely, good corporate governance and high positive media coverage can weaken this positive correlation. The additional analysis reveals that the number of RPTs and better market performance in the future can be significantly reduced when minority shareholders express their nonagreeable voice actively.

This paper analytically and empirically examines the impact of minority shareholders’ attendance in shareholders’ meetings on the voting results of RPT proposals based on the hand-collected voting data of Chinese listed companies. It provides direct and convincing evidence for the impact of minority shareholders’ attendance and exercise of voting rights in shareholders’ meetings on the outcome of RPT proposals. It complements the literature on the governance effects of minority shareholders’ attendance in shareholders’ meetings to exercise their voting rights in emerging capital markets. This study has practical value by guiding minority investors to participate actively in corporate governance.

This paper discusses whether institutional investors change the shareholding ratio of listed companies through research meeting, and whether this active investment mode can really improve the investment efficiency of institutional investors.

Using empirical research method, this study designs and conducts an empirical research according to empirical research's basic norms. Thus, we acquire needed and credible empirical data. This study analyzes whether institutional investors seek their private interest in researched companies by analyzing their research meetings and the shareholding ratios of different types of institutional investors using Shenzhen Stock Exchange data on listed firms from 2014 to 2018.

This study finds that the research meetings of institutional investors provide participants with reliable information which supports the decision of institutional investors to change their shareholding ratio. The stock price growth rate strengthens the positive correlation between the research meetings of institutional investors and the shareholding ratio of institutional investors. Additionally, transactional institutional investors increase the shareholding ratio, while holding institutional investors do not.

This paper combines the behavior of institutional investors with the holding status of institutional investors, and discusses the impact of institutional investors' behavior on investment decisions. At the same time, it classifies the institutional investors and discusses the attitude of different types of institutional investors towards this active investment mode.

In this study, the authors argue that the private information obtained and transmitted by institutions during the corporate visits can alleviate the degree of information asymmetry between firms and investors, so institutional visits may influence investors' heterogeneous beliefs. Therefore, the authors investigated whether and how institutional investors' corporate visits affect investors' heterogeneous beliefs.

This study examines whether and how institutional investors' corporate visits affect investors' heterogeneous beliefs using the data of A-share companies from the Shenzhen Stock Exchange (SZSE) during 2013–2019. Using empirical research method, this study designs and conducts an empirical research according to empirical research's basic norms.

The authors find that institutional visits effectively decrease investors' heterogeneous beliefs, especially institutional investors. Meanwhile, institutional site visits and sell-side institutional visits have a more significant negative effect on investors' heterogeneous beliefs. The findings remain after robustness tests with the alternative variable, instrumental variable, propensity score matching and quantile regression methods.

The development of China's capital market is imperfect, resulting in a strong speculative atmosphere. So, investors' irrational investment behaviors occur from time to time, leading to sizeable heterogeneous beliefs in China's capital market, which increases the risk of investment and is not conducive to the discovery of corporate value and the efficient allocation of resources. Therefore, exploring the factors influencing heterogeneous beliefs and finding ways to alleviate heterogeneous beliefs can reduce the proportion of speculative investors and promote the healthy development of China's capital market.

The purpose of this paper is to empirically analyze the relationship between institutional investors research meeting and performance of companies being researched.

Using empirical research method, this study designs and conducts an empirical research according to empirical research’s basic norms. Thus, the authors acquire needed and credible empirical data.

By analyzing the empirical data, there is a significant positive effect between institutional investors research meeting and the earnings per share of company being researched. Improvement in the level of the research meetings of the institutional investors strengthens the external supervision of management, alleviates the information asymmetry between management and shareholders, improves the management efficiency of the company and ultimately increases the performance of the company. When the performance of a company is better, we can find that the role of II research meetings is more significant. In addition, II research meetings are better able to improve the performance of state-owned enterprises.

This study empirically analyzes and verifies the roles of institutional investors research meeting in improve the performance of the company being researched. The authors expand the channel of institutional investors research behaviors to improve the performance of listed companies by strengthening the supervision and restraint of management behavior. Additionally, via a reverse study, it is found that the situation of the researched company itself is also one of the factors that determine the results of institutional investors research meetings.

The purpose of this paper is to analyze the relationship among negative media coverage, law environment and tunneling of controlling shareholders.

Under the Chinese especial institutional background, this paper empirically test the relationship among negative media coverage, law environment and tunneling of controlling shareholders with the sample of 2009-2011 Chinese listed companies.

The empirical results demonstrate that negative media coverage can reduce tunneling of controlling shareholder, and compared with state-owned listed companies, negative media coverage have a greater effect on tunneling in non-state-owned listed companies; and negative media coverage have a greater effect on tunneling in areas with better law environment. Further study shows that the reduction of controlling shareholder’s behavior of tunneling can improve company performance, and the improvement is more significant in non-state-owned listed companies and areas with better law environment. The research results indicate that media coverage play a very active role on restraining stakeholder’s behavior and perfecting corporate governing.

First, this paper will study of tunneling from the perspective of media coverage for the first time. Second, this paper further analyzes how the decrease of tunneling improves corporate performance following the research of how media coverage influence tunneling. Third, this study enrich literatures about the effects of media coverage on corporate governance in Chinese capital market.

Established on the detailed exploration of Chinese ancient management philosophies (CAMPs), the purpose of this paper is to extract enlightenments from CAMPs to see whether there exist some similarities between CAMPs and contemporary human resources management thoughts (CHRMTs) and pinpoint CAMPs' implications on human resource management practices nowadays.

Inspired by Lao Tzu's “When we can lay hold of the Dao of old to direct the things of the present day, and are able to know it as it was of old in the beginning, this is called (unwinding) the clue of Dao”, the paper explores, categorizes and integrates wisdom stemmed from CAMPs to evaluate whether there exist some commonly accepted arguments between CAMPs and CHRMTs.

CAMPs which have been passed on by generations for the past 2,500 years in China provide firm ground for human resources management thoughts and practices development; CAMPs' emphasis on people's well cultured morality and highly developed virtues has kindled a light to illuminate human resources management practices, not only in the past but also in the future. CHRMTs' principles concerning “people‐centered strategies”, employee recruitment and selection strategies, employee training and education strategies, staffing as well as employee retention strategies, can all trace their sources from CAMPs.

The research on CAMPs is not only significant to complement and extend CHRMTs but also useful to direct current human resource management practices.

South Koreans in the city of Ulsan claim that eating whale meat is a tradition, but what is the role of SMOs in making whaling into a tradition identified with a local identity? In following account of a confrontation that took place in Korea between anti-whaling protesters from Greenpeace and local defenders of whaling, it is shown that tradition is not an inevitable outcome of conserving the past; instead, it is an outcome of mobilization, framing, and choices made by movement participants. Tradition in the whaling town of Ulsan was formed through the encounter between opposed social movements, prompting strategic choices of counterframing, frame bridging, and the dissonance between framing and feeling rules. Through the encounters with transnational activists, the Korean defenders of whaling refashioned themselves as rooted cosmopolitans, utilizing global norms to justify local practices in the name of heritage and tradition.

This paper aims to explore the key risk factors affecting the Personnel Localization Management of international construction projects under the major public emergencies represented by the novel coronavirus pneumonia pandemic (hereinafter COVID-19) and how the public emergency affected the Personnel Localization Management from three levels: staff turnover rate, the number of different personnel, the salary and performance of workers. The paper also helps to enhance the construction enterprises' response capacity of major public emergencies and provides a comprehensive framework of optimization strategies for the Personnel Localization Management of international construction projects (hereinafter projects).

The main research method of this paper is the case study, and ten representative international construction projects are selected for case study in China construction enterprises (hereinafter CCE). And this study used the failure mode and effects analysis (FMEA) and comparative analysis to find out all potential risk factors under the COVID-19 and analyze how the epidemic affects the Personnel Localization Management of projects which based on the primary data from 10 projects obtained through in-depth interviews and the secondary data from China First Metallurgical Group and Central South Construction Group's Overseas Enterprise.

The findings show that the outbreak of the major public emergencies not only greatly increased eight risk factors but also directly led to an increase in staff turnover rate. Meanwhile, the numbers of Chinese and local managers and workers are all affected, and an increase in the number and the salary performance of local workers can be reduced, to a certain extent, to the cost-to-output ratio of the projects. The findings would help construction enterprises better cope with Personnel Localization Management and enhance the response capacity of major public emergencies.

This study will broaden researchers' horizons regarding “Personnel Localization Management under major public emergencies” and “risk factors of Personnel Localization Management in an international context.” Furthermore, construction enterprises looking for a better mechanism of Personnel Localization Management can benefit from research findings and lessons learned from the authors' case study during or before an outbreak of major public emergency. Lastly, the framework of optimization strategies for Personnel Localization Management can be used both for research purposes and practice issues in international construction projects.

The findings from the authors' case study offer the direction for international construction enterprises in China and other countries to formulate effective measures, strengthen overseas business and establish a crisis management mechanism for Personnel Localization Management under major public emergencies, and the findings provide emergency plans for projects to improve the public crisis handling capacity and respond to major public emergencies such as the COVID-19.

This study analyzes the impact of the COVID-19 on the Personnel Localization Management of international construction projects from the perspective of personnel. This study provides a theoretical reference for the international construction industry to actively respond to major public emergencies. Besides, the research is conducive to improving the emergency response mechanism in the construction industry, and further promoting the high-quality and globalized development of international construction.

This study provides other researchers with a comprehensive understanding of the risk factors affecting the Personnel Localization Management of projects under the COVID-19 and insight for further research on localization management, risk management, and project management.
