Nowadays Bitcoin as cryptocurrency takes a significant place on the global financial markets. This paper analyzes the Bitcoin closing prices and traded volume during the period from December 28, 2013 to January 22, 2019. This period is known as a period with rapid increasing of the Bitcoin closing prices, mainly in the second half of the year 2017. The aim of this paper is twofold. First, we compute the Hurst coefficient to discover the close price dynamics and traded volume using a fractal point of view. We have discovered an anti-persistent behavior in the traded volume and random character of bitcoin closing prices. Second, we propose an analysis of the relationship between the close prices and traded volume. Our findings show how changes in the high-price period differ from changes in the low-price period. We also found that high prices caused investors to be afraid to trade due to possible rapid decrease in bitcoin closing prices.

The aim of the study was to study the ethical and deontological aspects related to the professional activities of pharmacists. Materials and methods. To achieve the goal of the study, an analysis of scientific sources on ethical and deontological issues related to the professional activities of pharmacists (pharmacists) was carried. During the research, the methods of information search, systematization, comparison, and generalization, as well as sociological research methods were used. The object of the study was the results of questionnaires and interviews of visitors and employees of pharmacy chains of KP “Prymula”; pharmacy chains that are part of the company “Apteka-Mahnoliia”: Pharmacy ANC, Kopiika and pharmacies of the social project “Blahodiia”; pharmacy chains that are part of the company Med-service. Descriptive statistics methods were used to present the obtained data. To determine the significance of individual factors (Wij), obtained because of the questionnaire are listed to the corresponding specific weight of the component. Results. The systematization of the following factors: which determine the quality of service; related to the purchase of drugs (medicines); which determine the priority of qualities of pharmacies; determining the relationship between a pharmacist and a doctor. It was found that the most negative impact on pharmacy visitors, from the point of view of consumers, was the inattention of the pharmacist, his mistakes, irritability, rudeness, incompetence, as well as the high price of drugs, queues, and slow service. From the point of view of pharmacists, pharmacy visitors were most negatively affected by rudeness, incompetence of pharmacy employees, irritability, the price of drugs, the range of drugs, the presence of queues, and slow service. The results of the assessment of the parameters that determine the relationship between the pharmacist and the doctor showed that, in general, pharmacists maintain the authority of the doctor in the eyes of visitors and, along with the latter, carry out educational work among the population. However, a fifth of respondents assume the functions of a doctor, which is completely unacceptable. Using the technology of sociological survey, the analysis was carried out and, based on ranking, the leading rational and emotional factors that form loyalty for certain segments of the professional activity of pharmacies using ethical and deontological principles were identified. Conclusions. The systematization of the following factors: which determine the quality of service; related to the purchase of drugs that cause dissatisfaction; which determine the dissatisfaction of visitors to pharmacies; which determine the priority of qualities of pharmacies; determining the relationship between pharmacist and doctor. Using the technology of sociological survey, the analysis was carried out and, based on ranking, the leading rational and emotional factors that form loyalty for certain segments of the professional activity of pharmacies using ethical and deontological principles were identified. It is established that the views on consumer dissatisfaction with visiting pharmacies differ insignificantly from the views of pharmacists. Pharmacist visitors are most negatively affected by the inattention and rudeness of the pharmacist, the high price of drugs, the presence of queues and slow service. It is established that, in general, pharmacists maintain the authority of the doctor in the eyes of visitors and, along with the latter, conduct educational work among the population.

This paper presents the results of fractal analysis of models of texts of different styles. Integer numerical sequences, the elements of which are the number of letters in the words of the text, are used as models. An algorithm for calculating the exact value of the fractal dimension is presented, which provided the determination of the exact value of the Hirst index. In addition, the value of the power dependence constant R / S is calculated. The obtained indicators in the aspect of fractality fully describe the objects of research. This method is in fact a logical implementation of the known procedures of fractal analysis and its advantage is that it provides a rigorous mathematical representation of the values of the fractal dimension, the Hirst index and the constant in relation to the indicators of variation. The essence of his presentation is, first of all, as a warning to researchers against misinterpretation of the relationship R / S, because many researchers ignore the existence of a constant for this relationship. Indeed, this relation is a function with two unknown parameters and cannot be directly determined. With regard to the fractal dimension, we can point out that the least important is the conversational style, and the most – poetic. In other words, the model of colloquial text is the smallest part of its environment, poetic – the largest. From the point of view of Hirst’s index, the model of the spoken text contains a trend, while the model of the poem has a character closer to the random one. The largest scope of the cumulative series has a model of spoken text, and the smallest – a model of artistic style of the text. Since the cumulative series is a sequential (cumulative) summation of the sequence of deviations of elements from its arithmetic mean, its scope will depend on the presence of groups of elements of the sequence with very large deviations. Artistic style has the least significance of scope.

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.

Well-functioning financial markets can have a positive effect on economic growth by facilitating savings and more efficient allocation of capital. This paper characterises some of the recent theoretical developments that analyse the relationship between financial intermediation and economic growth and presents empirical estimates based on a model of the linkage between financially intermediated investment and growth for two separate groups of countries, developing and advanced. Empirical estimates for both groups suggest that financial intermediation through the efficiency of investment leads to a higher rate of growth per capita. The relevant coefficient estimates show a higher level of significance for the developing countries. This financial liberalisation in the form of deregulation and establishment and development of stock markets can be expected to lead to enhanced economic growth.

This text is an attempt to see sport in different ways in the light of ancient philosophical themes. Philosophy of sports gets less attention than other areas of the discipline that examine the other major components of contemporary society: philosophy of religion, political philosophy, aesthetics, and philosophy of science. Talking about sports is often cheap, but it does not have to be that way. One of the reasons for this is insufficiently paid attention to the relation between sport and philosophy in Greek. That is it's important to talk about sports, just as important as we are talking about religion, politics, art and science. The argument of the present text is that we can try to get a handle philosophically on sports by examining it in light of several key idea from ancient Greek philosophy. The ancient Greeks, tended to be hylomorphists who gloried in both physical and mental achievement. Тhe key concepts from Greek philosophy that will provide the support to the present text are the following: arete, sophrosyne, dynamis and kalokagathia. These ideals never were parts of a realized utopia in the ancient world, but rather provided a horizon of meaning. We will claim that these ideals still provide worthy standards that can facilitate in us a better understanding of what sports is and what it could be. How can a constructive dialogue be developed which would discuss differences in understanding of sport in Ancient Greece and today? In this paper, the authors will try to answer this question from a historical and philosophical point of view. The paper is divided into three sections. The first section of the paper presents two principally different forms or models of focus in sport competitions – focus on physical excellence or focus on game. The dialectic discourse regarding these two approaches to physical activity is even more interesting due to the fact that these two models take precedence over one another depending on context. In the second section of the paper, the focus shifts to theendemic phenomenon of the Ancient Greek Olympic Games, where the topic is discussed from the perspective of philosophy with frequent historical reflections on the necessary specifics, which observeman as a physical-psychological-social-spiritual being. In the third section of this paper, the authors choose to use the thoughts and sayings of the great philosopher Plato to indicate how much this philosopher wasactually interested in the relationship between soul and body, mostly through physical exercise and sport, because it seems that philosophers who came after him have not seriously dealt with this topic in Plato’s way, although they could.

This article studies the cognitive features of the “power” frame and its gender implementation in the historical tragedy by W. Shakespeare “Macbeth”. Here, the author examines the concepts of “frame” and “gender” in linguistics, studying different approaches to their definition. The relevance of this work is determined by the close attention of the contemporary linguistics to these concepts, as well as their place in the contemporary academic paradigm. The academic affirmation of the “frame” and “gender” concepts designates a new step in understanding the ways and peculiarities of the language interaction, consciousness, and culture, and, consequently, it shows new aspects of the relationship of linguistics with other sciences. Nevertheless, the problems of both frame and gender are not yet fully understood. This study allows describing in detail the essence of the frame “power” and showing its meaning, use, and ways of its gender implementation in fiction, which explains the novelty of this article. The study’s methodology is based on the cognitive-discursive analysis of the text, as well as on an integrative approach to the discourse study, which combines methods of both cognitive and gender linguistics, as well as the discourse analysis. Common research methods were used along with private linguistic methods. The application of cognitive-discursive analysis has significantly increased the depth of understanding of the “power” frame that dominates Shakespeare’s historical tragedy. This historical text presents the central theme of political tragedy: the overthrow of the rightful ruler and the usurpation of power. The motive for the seizure of power forms a thematic core and is presented from the usurpers’ point of view. In this article, the author observes the gender shift and duality of the female and male beginnings: Shakespeare puts the female protagonist, hungry for power, among men, thus the images of Lady Macbeth and her husband come into conflict with the gender characteristics attributed to them. The play clearly traces the main idea of Machiavellianism: the goal justifies the means. The results conclude that the “power” frame is the leading one in Lady Macbeth’s monologue, thus setting one of the main themes of this tragedy.


This book focuses on the relationship between private and public education in a comparative context. The contributors emphasize the relationship between private choices and public policy as they affect the division of labor between public and private non-profit schools, colleges, and universities. Their essays examine the kinds of choices offered by each sector, as well as the effects of present and proposed public policies on the intersectoral division of labor. Written from neither a pro-private nor a pro-public point of view, the contributors point to the ways in which they believe one sector or the other may be preferable for certain goals or groups.

“Canadian cinema.” The term may appear self-evident but is problematic. First, one may question the value of national approaches to culture, especially here, in Quebec and Canada, where the debates over the Nation seem interminable, and especially now, in an era of globalization. Next, one may question the value of media-centered approaches to culture, especially when the successive waves of the “digital revolution” have blurred the boundaries between technologies and among artistic practices. Rather than try to survey “important” fiction films for theatres in Quebec or Canada, this essay adopts another point of view to examine the presence of cinema in Montreal museums over the past few years by focusing on three singular exhibitions. It may well be symptomatic of the current state of film in Quebec and Canada—but also, paradoxically, everywhere else—and says much about the relationship between medium and nation, the expansion of cinema beyond the movie theatre, and the internationalization of culture.
