Abstract Accurately and objectively simulating the dynamic evolution of the behaviors of different decision-makers (DMs) is essential for identifying solutions to transboundary water conflicts. This research proposes an improved Graph Model for Conflict Resolution (GMCR) based on the benefits of DMs’ behaviors to model the dynamic evolution of transboundary water conflicts. Additionally, the influence of third-party intervention on conflicts is investigated in depth. A demonstration area in the Yangtze River Delta on ecologically friendly development (DAYRD) in China is taken as the case study area. The results indicate that the improved GMCR model based on the benefit function can not only clearly identify the dynamic evolution path of transboundary water conflicts into cooperation, but also effectively avoid the influence of the subjective factors of researchers or experts in traditional methods. In addition, a third party with higher powers is the key to resolving transboundary water conflicts in the DAYRD. The implementation of punishment measures by a third party can change the status quo of water conflicts and boost effective cooperation among governments. The punishment amount should be greater than the protection costs shared by local governments. These findings provide experience for the resolution of transboundary water conflicts and enhance our understanding of the role of third parties in transforming conflict into cooperation.

Stream structure is usually dominated by various human activities over a short term. An analysis of variation in stream structure from 1979 to 2009 in the Qinhuai River Basin, China, was performed based on remote sensing images and topographic maps by using ArcGIS. A series of river parameters derived from river geomorphology are listed to describe the status of river structure in the past and present. Results showed that urbanization caused a huge increase in the impervious area. The number of rivers in the study area has decreased and length of rivers has shortened. Over the 30 years, there was a 41.03% decrease in river length. Complexity and stability of streams have also changed and consequently the storage capacities of river channels in intensively urbanized areas are much lower than in moderately urbanized areas, indicating a greater risk of floods. Therefore, more attention should be paid to the urban disturbance to rivers.

Tracking scientific and technological (S&T) research hotspots can help scholars to grasp the status of current research and develop regular patterns in the field over time. It contributes to the generation of new ideas and plays an important role in promoting the writing of scientific research projects and scientific papers. Patents are important S&T resources, which can reflect the development status of the field. In this paper, we use topic modeling, topic intensity, and evolutionary computing models to discover research hotspots and development trends in the field of blockchain patents. First, we propose a time-based dynamic latent Dirichlet allocation (TDLDA) modeling method based on a probabilistic graph model and knowledge representation learning for patent text mining. Second, we present a computational model, topic intensity (TI), that expresses the topic strength and evolution. Finally, the point-wise mutual information (PMI) value is used to evaluate topic quality. We obtain 20 hot topics through TDLDA experiments and rank them according to the strength calculation model. The topic evolution model is used to analyze the topic evolution trend from the perspectives of rising, falling, and stable. From the experiments we found that 8 topics showed an upward trend, 6 topics showed a downward trend, and 6 topics became stable or fluctuated. Compared with the baseline method, TDLDA can have the best effect when K is 40 or less. TDLDA is an effective topic model that can extract hot topics and evolution trends of blockchain patent texts, which helps researchers to more accurately grasp the research direction and improves the quality of project application and paper writing in the blockchain technology domain.

The participation of a third party of the environmental service enterprise theoretically increases the level and efficiency of soil pollution control in China. However, Chinese-style fiscal decentralization may have a negative impact on the behaviors of participants, especially the local government. First, this paper conducts a positioning analysis on participants of the third-party soil pollution control in China and discusses the behavioral dissimilation of the local government under fiscal decentralization. Second, taking the government’s third-party soil pollution control as a case, a two-party game model of the central government and the local government is established around the principal-agent relationship, and a tripartite game model of the central government, the local government, and the third-party enterprise is designed around the collusion between the local government and the third-party enterprise. The results show that Chinese-style fiscal decentralization may lead to the behavioral dissimilation of local governments, that is, they may choose not to implement or passively implement the third-party control, and choose to conspire with third-party enterprises. Improving the benefits from implementing the third-party control of local governments and third-party enterprises, enhancing the central government’s supervision probability and capacity, and strengthening the central government’s punishment for behavioral dissimilation are conducive to the implementation of the third-party soil pollution control. Finally, this study puts forward policy suggestions on dividing the administrative powers between the central and local government in third-party control, building appraisal systems for the local government’s environmental protection performance, constructing environmental regulation mechanisms involving the government, market and society, and formulating the incentive and restraint policies for the participants in the third-party soil pollution control.

In recent years, air pollution caused by PM2.5 in China has become increasingly severe. This study applied a Bayesian space–time hierarchy model to reveal the spatiotemporal heterogeneity of the PM2.5 concentrations in China. In addition, the relationship between meteorological and socioeconomic factors and their interaction with PM2.5 during 2000–2018 was investigated based on the GeoDetector model. Results suggested that the concentration of PM2.5 across China first increased and then decreased between 2000 and 2018. Geographically, the North China Plain and the Yangtze River Delta were high PM2.5 pollution areas, while Northeast and Southwest China are regarded as low-risk areas for PM2.5 pollution. Meanwhile, in Northern and Southern China, the population density was the most important socioeconomic factor affecting PM2.5 with q values of 0.62 and 0.66, respectively; the main meteorological factors affecting PM2.5 were air temperature and vapor pressure, with q values of 0.64 and 0.68, respectively. These results are conducive to our in-depth understanding of the status of PM2.5 pollution in China and provide an important reference for the future direction of PM2.5 pollution control.

Aviation business is a capital intensive and high risk in terms of safety. Legislation in force in Indonesia requires enterprises should cost in the form of a limited liability company that is obliged to deposit the basic capital of 500 billion rupiah. The capital cannot be made in working capital which is useful for the collateral to a third party. The regulations for a limited liability company are to be established by at least 2 people. The purpose of this research is to analyze the linkage of the board directors and the status of aviation industry licensing law. The position of the legal status of business entities where shareholder is only one person is to be studied in this descriptive study. The result shows that the airlines company should provide the capital risk and high insurance of the third party. UUPT also has given the authority of the shareholders (who owns 20 % of the share) to be decision makers in the company. However, without independent surveillance, it is possible that the shareholders do some mistakes in making decisions. Some mistakes are related to the policy, the using of authorized capital, and others. Aviation business is a capital intensive and high risk in terms of safety.

The relevance of the article is that the granting of special status «child divorced from the family» in the Ukrainian legislation includes three aspects: 1) identification of a person who is a child separated from the family; 2) granting the status of «child deprived of parental care»; 3) it is possible to grant the status of “refugee” or “person in need of additional protection”, as any person recognized as a child divorced from a family is recognized as a child deprived of parental care and can apply for asylum in Ukraine (and receive refugee status or a person in need of additional protection). Each of the identified aspects of the above status is the responsibility of certain public authorities, ie public administration entities, which are endowed with the appropriate powers. The purpose of the article is to identify the subjects of administrative and legal support for the identification of children separated from their families, ie the subjects of public administration, which are empowered to identify such children in Ukraine. It was found that in fact, the identification of a child separated from the family at the present stage in Ukraine does not belong to the responsibilities of public administration, but is the responsibility of the child who was forced to leave the country of origin or residence and arrived in the territory of Ukraine unaccompanied by a family member or persons determined by law/custom who are responsible for such a person, or who were left unaccompanied after arriving on the territory of Ukraine, or its legal representatives. In our opinion, the absence in the legal acts that determine the legal status of public administration entities, whose activities include the identification of children separated from their families, their obligation to identify such children is a shortcoming of administrative and legal support for child status. , separated from her family, in Ukraine. It is determined that the subjects of public administration, which have the authority to identify children separated from their families, include the State Border Guard Service of Ukraine, executive authorities, local governments, the National Police of Ukraine, the Prosecutor’s Office of Ukraine.
