AbstractIn this paper, we investigate the problem of combating terrorism by the government, which is one of the most serious problems that direct governments and countries. We formulate the problem and use the Nash approach of a differential game to obtain the optimal strategies for combating terrorism. We study the relationship between each of the government’ strategies and terrorism when the government is on the defensive (reactive), and we study when the government expects terrorist attacks and develops its strategies to combat terrorism. Also, we study the relationship between government activity and its strategies as well as government activity and the strategy of terrorist organizations.

Abstract Based on the “three bottom line” and stakeholder theory, the paper considers the relationship and cooperation strategy between the government and the supplier and manufacturer of the green supply chain. By constructing the dynamic differential game model, the paper discusses the differences in the optimal effort level, green degree of product, reputation and the optimal benefit under the three situations of noncooperation, government promotion and collaborative cooperation. The results show that the optimal effort level, green degree of product, reputation and the optimal benefit in collaborative cooperation are obviously higher than the situations of non-cooperation and government promotion, and the cooperation of the three parties can promote the development of green supply chain. Government promotion is better than noncooperation. The government plays an active role in improving the optimal benefit and reputation of green supply chain. Finally, the reliability of the proposed proposition is verified by an example analysis, which provides an important reference for improving the efficiency of green supply chain.

This paper studies a three player hierarchical differential game (with a large country, a small country, and a terrorist organization), to analyze the actual European refugee situation. Terrorists may enter Europe as refugees, taking advantage of the Open Door Policy, to attack both countries. There are two scenarios: myopia and full awareness. Countries are myopic when they ignore each other’s security efforts, and the terrorist group only considers the weakest link’s security efforts. A comparison between the scenarios shows that for an extremely impatient large country, full awareness yields a greater level of security effort for the large country, a greater level of security effort for the small country, and more terrorist attacks. This is, however, an unstable equilibrium. The full awareness model with a patient large country is stable and lies in between the previous model and the myopic model. Although it yields larger investments in security, this still results in more terrorist attacks than the myopic model. Continental safety is higher in the myopic model than in the full awareness model.

In this work, by using the Nash-collative approach for a differential game problem between N -governments and terrorist organizations, we study governments’ cooperation and the role of each government for counterterrorism. Furthermore, we discuss the intertemporal strategic interaction of governments and terrorist organizations, where all world governments have to cooperate to fight terrorism. Also, we study the necessary conditions for finding the optimal strategies for each government to fight terrorism; we discuss the existence of the solution of the formulated problem and the stability set of the first kind of the optimal strategies.

This study is based on the legal responsibility of the assessment of public appraisal reports they make in land procurement activities for development in the public interest. Public assessment is obliged to always be accountable for their assessment. The type of research found in this thesis is a type of normative legal research with the right-hand of the statue approach and case approach. Normative legal research is a study that provides systematic explanation of rules governing a certain legal category, analyzing the relationship between regulations explaining areas of difficulty and possibly predicting future development. . After conducting research, researchers found that one of the causes that made the dispute was a lack of communication conducted between the Government and the landlord. In deliberation which should be the place where the parties find the meeting point between the parties on the magnitude of the damages that will be given, in the field is often used only for the delivery of the assessment of the compensation that has been done.

The article examines the relationship between Western Russianism (Zapadnorusizm) and Byelorussian nationalism. Byelorussian nationalism is much younger than Western Russianism, finally shaping only in the end of the 19th century. Before 1917 revolution Byelorussian nationalism could not compete with Western Russianism. The national policy of the Bolsheviks contributed to the decline of Western Russianism and helped Byelorussian nationalism to gain stronger positions. However, Byelorussian nationalists actively cooperated with the occupation authorities during the Great Patriotic war. That caused distinctly negative attitude of Byelorussians towards the movement and collaborators. Currently, Byelorussian nationalism is supported both by the opposition and by the government. Western Russianism has no political representation, but is supported by the majority of Byelorussian population.

This article aims to explore the relationship between the Ministry of Home Affairs (Kemendagri) and the Ministry of Villages (Kemendes) from theconstitutional law and state administrative law point of view.The second concerns of this research is the disharmony and problem between the two ministries.From the constitutional law point of view, it turns out that what the Ministry of Home Affairs is doing, is closer to the object of its discussion. The method used in this research is normative legal research bycomparingthe constitutional law and state administrative law to obtain clarity regarding the Ministry of Home Affairs and Ministry of Village. The result shows that the Ministry of Village approached the science of state administrative law, namely to revive or give spirits to the village. Disharmonization began to exist since the inception of the Ministry of Village. The root of disharmony itself was the improper application of constitutional foundations in the formation of the Village Law. It would be better if the government reassess the constitutional foundation for the village.

Abstract A recently published paper in this journal (Choi, 2021) establishes a statistical link between, on the one hand, Islamist terrorist campaigns – including terrorist attacks and online propaganda – and, on the other the growth of the Muslim population. The author explains this result by stating that successful campaigns lead some individuals to convert to Islam. In this commentary, we intend to reply to this article by focusing on the impact of terrorist attacks on religious conversion. We first show that Choi's results suffer from theoretical flaws – a failure to comprehensively unpack the link between violence and conversion – and methodological shortcomings – a focus on all terrorist groups over a period where Islamist attacks were rare. This leads us to replicate Choi's analysis by distinguishing Islamist and non-Islamist terror attacks on a more adequate timeframe. By doing so, we no longer find empirical support for the relationship between terror attacks and the growth of the Muslim population. However, our analyses suggest that such a hypothesis may hold but only in contexts where the level and intensity of political violence are high.

Abstract Four chronicles written by Alberto Blest Gana between April and May 1862 in the newspaper La voz de Chile, months before the publication of his novel Mariluán, shed light on the close relationship between his production as chronicler and writer. Among the various faits divers discussed in the columns, the issue of a Mapuche delegation’s arrival in Santiago to hold a parlamento with the government about border disputes arises. The oscillating attitude of the chronicler in the face of otherness and his prejudiced comments, which are at the same time full of doubts and perplexities, serve as an incentive for his composing a utopian fiction. This article aims to examine the connections in the relationship between Blest Gana chronicler and novelist to expand the reading possibilities of Mariluán.
