This paper's purpose was to identify the key sources when formulating competitive advantages of hotel chains. The research assessed the financial activities performance included in annual hospitality industry reports and on their official websites; questioning of loyal and potential customers; the five-point Likert scale and the Pearson correlation coefficient were applied to understand the possible consumer reaction to a certain competitive advantage or its absence. The paper confirms the effectiveness of key sources used by management to win and retain competitive (...) advantages: despite strong dependence on the economic cycle phase etc., after the devastating crisis of 2007, 2008, but also to achieve sustainable growth. All the networks examined over the last decade have expanded their presence in international markets, diversified the portfolio of brands, increased the number of jobs and profits. It was also proved that the opinion of the final consumer is still not sufficiently taken into account in the assessment of the Pearson correlation coefficient (the latter allowed the authors to propose their own definition of the competitive advantage in the industry). The paper attempts for the first time to consider the competitive advantages of hotel chains from the point of view not only of theorists and business practitioners, but also with the view of the opinion of the services consumer; there were identified the discrepancies, which consideration would allow to increase the level of guest satisfaction and, accordingly, the efficiency of the hotel business. In future papers, the authors plan to verify the existence of a correlation between the degree of guest loyalty to a particular hotel network and the main financial results of its activities.

The application of modern technologies with artificial intelligence (AI) in all spheres of human life is growing exponentially alongside concern for its controllability. The lack of public, state, and international control over AI technologies creates large-scale risks of using such software and hardware that (un)intentionally harm humanity. The events of recent month and years, specifically regarding the Russian Federation’s war against its democratic neighbour Ukraine and other international conflicts of note, support the thesis that the uncontrolled use of AI, especially (...) in the military sphere, may lead to deliberate disregard for the moral standards of controlled AI or the spontaneous emergence of aggressive autonomous AI. The development of legal regulation for the use of technologies with AI is prolonged concerning the rapid development of these artefacts, which simultaneously cover all areas of public relations. Therefore, control over the creation and use of AI should be carried out not only by purely technical regulation (e.g., technical standards and conformance assessments, corporate and developer regulations, requirements enforced through industry-wide ethical codes); but also by comprehensive legislation and intergovernmental oversight bodies that codify and enforce specific changes in the rights and duties of legal persons. This article shall present the “Morality Problem” and “Intentionality Problem” of AI, and reflect upon various lacunae that arise when implementing AI for military purposes. (shrink)

The article focuses on the study of specific characteristics of seaports development under conditions of digitalization. The article aims to study features of the development of the international seaport under digitalization to implement the best achievements in Ukraine. The main research method was a systemic-structural approach used to examine seaport digitalization as a part of a logistics chain, including horizontal and vertical links between its elements. To achieve an effective digital transformation, we also used the above method. It helped to (...) study how the factors determined during the study of international practices and possible innovations influence the object under study. The practices, which are of interest for Ukraine and other developing countries, were identified based on the international experience in seaports development under digitalization. The main strategic directions for the digital transformations of the above infrastructural objects were suggested. They involve increasing seaport competitiveness and their effectiveness in the framework of the international transport system. The directions are of interest for public authorities of the governmental and regional levels (while establishing the digitalization policy in the area of sea transport) and the port administrations (while making justified strategic decisions for their development).

The book will be useful for economists, finance and valuation professionals, market researchers, public policy analysts, data analysts, teachers or students in graduate-level classes. The book is aimed at students and beginners who are interested in forecasting modeling and analytics of economic processes and want to get an idea of its implementation.

In some recent papers (G. ‘t Hooft and others), it has been argued that quantum mechanics can arise from classical cellular automata. Nonetheless, G. Shpenkov has proved that the classical wave equation makes it possible to derive a periodic table of elements, which is very close to Mendeleyev’s one, and describe also other phenomena related to the structure of molecules. Hence the classical wave equation complements Schrödinger’s equation, which implies the appearance of a cellular automaton molecular model starting from (...) classical wave equation. The other studies show that the microworld is constituted as a tessellation of primary topological balls. The tessellattice becomes the origin of a submicrospic mechanics in which a quantum system is subdivided to two subsystems: the particle and its inerton cloud, which appears due to the interaction of the moving particle with oncoming cells of the tessellattice. The particle and its inerton cloud periodically change the momentum and hence move like a wave. The new approach allows us to correlate the Klein-Gordon equation with the deformation coat that is formed in the tessellatice around the particle. The submicroscopic approach shows that the source of any type of wave movements including the Klein-Gordon, Schrödinger, and classical wave equations is hidden in the tessellattice and its basic exciations – inertons, carriers of mass and inert properies of matter. We also discuss possible correspondence with Konrad Zuse’s calculating space. (shrink)
