What are the implications of Curriculum Learning strategy on IRL methods?: Investigating Inverse Reinforcement Learning from Human Behavior
No full textInverse Reinforcement Learning (IRL) is a subfield of Reinforcement Learning (RL) that focuses on recovering the reward function using expert demonstrations. In the field of IRL, Adversarial IRL (AIRL) is a promising algorithm that is postulated to recover non-linear rewards in environments with unknown dynamics. This study investigates the potential benefits of applying the Curriculum Learning (CL) strategy to the AIRL algorithm. For our experiments, we use a randomized partially observable Markov decision process in the form of a grid-world-like environment. Using only expert demonstrations obtained with an RL algorithm under the true reward function, we train AIRL in a variety of configurations and identify an effective curriculum. Our results show, that a well-constructed curriculum can enhance the performance of AIRL twofold in both key aspects: the speed of convergence and the efficiency of using expert demonstrations. We thus conclude that CL can be a useful addition to an AIRL-based solution.

Linguistic strategies for professional politeness among aspiring managers: An analysis of organizational psycholinguistics
No full textIn order to effectively communicate in a professional setting, it is essential for managers to have a mastery of the language specific to their field. One tool that can be used for professional communication is verbal politeness, which involves using appropriate words and phrases to show respect for the listener and soften unfavourable information. These linguistic units promote a culture of professionalism and ethical business relationships and are a key indicator of a manager's speech competence. A psycholinguistic study examined the usage of polite language by aspiring managers. The participants were 218 undergraduate and graduate students enrolled in the Management program across various universities in Ukraine's oblasts. The organizational psycholinguistics research aimed to assess the extent to which aspiring managers incorporate professional language units such as polite words and phrases in their speech. We analyzed the references of 1,308 respondents to determine how politeness language units corresponded to the structural parts of the document. By studying 928 selected language units of politeness, we could assess the level of politeness markers. This indicator reflects future managers' skill level in applying synonymous ranges of politeness. The analysis found that respondents used various linguistic units to soften the impact of unfavourable information when conveying it to others. These units formed synonymous ranges based on context and semantic content. Only half of the students showed a wide range of knowledge and skills in appropriately using polite language. Thus, aspiring managers need to improve their knowledge and practical skills in using a variety of linguistic units of politeness in business documents. Therefore, we recommend implementing programs to improve communication levels for those pursuing higher education in management.

Vlasenko V. A. Principle approach to managing the enterprise's investment activities in the conditions of safe implementation of real investment projects / International security studios : managerial, economic, technical, legal, environmental, informative and psychological aspects. International collective monograph. Tbilisi, Georgia : Georgian Aviation University, 2023. 1438 p. PP. 1293–1315
No full textThe conducted research is devoted to the problem of safe implementation of
real investment projects based on the application of a principled approach to managing the
enterprise's investment activities. The work substantiates the expediency of implementing a
real investment project of the production direction according to the main phases of the
investment cycle (pre-investment, investment and production). The stages of the investment
project development process at the enterprise are recommended based on their formalization in
the form of a project cycle, which will include the following stages: formulation of the
investment project (identification); development (preparation) of the investment project plan at
the enterprise; expertise (examination) of the investment project at the enterprise;
implementation of the investment project at the enterprise; assessment of the results of the
enterprise's investment project implementation. The author's version of the algorithm for the
process of developing the technical and economic justification of the investment project at the
enterprise is proposed. The stages of investment project development at the enterprise based on
the monitoring mechanism are summarized. It is recommended to supplement the operational
(production) stage of the project cycle at the enterprise with rehabilitation studies for
individual stages. During the research, it was proposed to implement a real investment project
– the launch of a qualitatively new technological line for the production of control and
measuring devices from environmentally friendly glass at the hypothetical enterprise. The
author recommends the components of the process of evaluating a real investment project or
drawing up a capital investment budget at the hypothetical enterprise. As a result of the
performance evaluation of the proposed real investment project for the hypothetical enterprise,
the feasibility of its implementation was proven by calculating the indicators of Net Present
Value (NPV), Profitability Index (PI), Internal Rate of Return on investments (IRR), Project
Payback Period (PP). The economic and operational characteristics of the proposed
development investment project at the hypothetical enterprise are summarized
How Smart City practices create comfortable environments for low mobile population groups
No full textThe article covers the arrangement of comfortable conditions for physically challenged and low mobile residents in urban environments. Currently, these social categories are discriminated in urban societies. Contemporary cities, their infrastructure fail to satisfy their needs. Their ability to move around and fulfill their potential in urban spaces is limited. In the article, the author provides the findings of the sociological survey, conducted in Novokuznetsk, Kemerovo region, in 2015 – 2016. The survey’s mission was to find out whether the principles of reasonable adjustment of an urban environment to the needs of various groups of residents needed to be integrated into the public policy. This problem turns particularly relevant in the context of the development and introduction of the Smart City practices

The author notes that the necessity of civic education of young people, the development of a unified state policy in the field of civic education and education, a national goal and a civic ideology that could consolidate Ukrainian society on the basis of national and civic values is now universally recognized.У статті автор досліджує сучасні підходи до визначення поняття «громадянськість», «громадянське суспільство», «громадянські цінності»; визначає характерні особливості різних наукових теорій у контексті проблеми формування активної громадянської позиції в освітньому середовищі навчального закладу. Також зазначається, що в даний час загальновизнаною є необхідність громадянського виховання молоді, розробки єдиної державної політики в галузі громадянської освіти та виховання, загальнонаціональної мети і громадянської ідеології, які могли б консолідувати українське суспільство на основі загальнонаціональних і громадянських цінностей
МОДЕРНИЗАЦИЯ КОНСТИТУЦИИ РОССИИ (К ИТОГАМ ОБСУЖДЕНИЯ В СВЯЗИ С 25-ЛЕТИЕМ)
No full textA quarter of a century has passed since the adoption of the Constitution of the Russian Federation by a national referendum. The jubilee gives a reason to talk about the optimality of constitutional provisions, their effectiveness, and somewhere practical expediency. The article aims to analyze the points of view expressed in this regard in the scientific press, newspaper periodicals and other media. However, the author first refers to the history of the emergence of the Constitution of the Russian Federation in 1993. It is noted that the Basic Law, on the one hand, was a result of military-political compromise between supporters of the parliamentary vision of the future structure of the country and supporters of a strong presidential power, on the other hand, allowed ultimately abolish the Soviet system and traditions. The mentioned situation and the factor of haste and hurry could not but affect the content and technical and legal quality of the document. The author has reduced the opinions expressed on the issue of modernization of the Constitution of the Russian Federation to three main positions: 1) The Constitution has not exhausted its potential and there is no reason to change its text; 2) a full-fledged constitutional reform is required, the current Constitution has exhausted its potential; 3) there is a need for precise partial changes and additions that can improve the Constitution. The article argues that the last position of the so-called precise partial changes is the most productive and allows to make the constitutional document adequate and relevant. In this regard, it is proposed to hold several round tables at the initial stage on the development of concepts for improving the constitutional foundations. One of them, the author calls promising and offers to prepare a list of proposals for the removal of ideologically and actually not confirmed in practical life provisions. These are provisions about Legal State (excluding the principle of separation of state power), Welfare State, etc. Another concept that also needs to be developed is institutional (the concept of the legal status of public authorities, their powers, checks and balances, etc.). These ideas, the author believes, should be a compromise between scientists, then become public and be implemented in the practice of constitutional construction.Прошло четверть века с момента принятия Конституции Российской Федерации всенародным референдумом. Юбилей дает повод порассуждать об оптимальности конституционных положений, их эффективности, а где-то и практической целесообразности. В статье поставлена задача проанализировать высказанные в этой связи точки зрения в научной печати, газетной периодике и других средствах массовой информации. Однако прежде автор уделяет внимание истории появления Конституции РФ 1993 года. Отмечается, что Основной Закон, с одной стороны, явился военно-политическим компромиссом между сторонниками парламентского видения устройства страны в будущем и сторонниками сильной президентской власти, с другой стороны, позволил полностью распрощаться с советскими строем и традициями. Данная ситуация и фактор торопливости, спешности не могли не повлиять на содержательное и технико-юридическое качество документа. Высказанные мнения по вопросу модернизации Конституции России автор свел к трем позициям: 1) Конституция не исчерпала своих возможностей, и трогать ее текст нет оснований; 2) необходима полноценная конституционная реформа, действующая Конституция свой потенциал исчерпала; 3) необходимы «точечные» изменения и дополнения, способные улучшить Конституцию. В статье аргументируется, что последняя позиция так называемых точечных изменений - наиболее продуктивна и позволяет конституционный документ сделать адекватным и актуальным. В этой связи на первоначальном этапе предлагается провести несколько «круглых столов» по вопросу выработки концепций совершенствования конституционных основ. Одну из них автор называет перспективной и предлагает подготовить перечень предложений по изъятию идеологически и фактически не подтвердивших себя в практической жизни положений. Речь идет о правовом государстве (исключая принцип разделения государственной власти), социальном государстве и т.д. Другую концепцию, которую также необходимо разработать, - это институциональную (концепцию статуса властей, их полномочий и баланса и др.). Данные идеи, считает автор, должны быть компромиссом между учеными, затем стать достоянием общественности и реализовываться в практику конституционного строительства

No full textSocial and legal regulators. Conceptual developments by V.I. Nizhechek
No full textThe role of the Soviet scientist-activist V.I. Nizhechek in the development and establishment of social regulation concepts, and its importance in governing societal affairs, as well as functions and potential of law, and its relationship with morality as a social regulator are thoroughtly explored. V.I. Nizhechek posits that legal and social regulations share a common nature, are deeply interconnected, and exhibit numerous practical manifestations of unity. While aknowledging the independent nature of law, the scientist concludes that legal norms essentially form a component of social regulation in society. Notably, the author emphasizes moral regulation, and the interplay between legal norms and morality, while examining various social regulators such as corporate norms, ethincs, religion, and others. V.I. Nizhechek does not differential between morality ad ethics; however, he asserts that morality holds a dominant role in the system of social regulation, highlighting the so-called “proximity” of morality and law. Morever, the author draws relevant parallels that substantiate the systematic nature of social regulation. V.I. Nizhechek delves into the crucial question of the theory of law as a tool of legal regulation in historical and contemporary contexts. He considers the evolution of legal regulation in terms of broadening its scope and reinforcing its role in Soviet society, unlimately concluding that legal regulation has become more complex. The concept of the intimate connection between economic and legal methods of regulation is presented; the author asserts that there may be no contradiction between these methods of regulation since all economic methods are mediated by legal norms. The material is prefaced by the author's personal recollections of meetings and conversations with V.I. Nizhechek, as well as with scholars, colleagues, who were associated with him
