Methodological approaches to the construction of an econometric model of hidden profits at the micro level

Application of econometric analysis methods to such relatively underexplored field of scientific knowledge as the shadow economy which is characterized by a higher degree of difficulty in getting its assessments forces in some cases to refuse to comply with mechanical use of econometric tools and formulate a number of assumptions without which the problem can not be solved. In order for the method worked well, it should be found a rational relationship between the source data, the prerequisites of the methods used, and the provisions of econometric theory. In addition, it is necessary to have a clear understanding of the socioeconomic cause-effect relationships between phenomena. As practice shows, availability of information only is insufficient to obtain reliable estimates of the shadow economy and the calculations associated with their prediction. There is currently no legally established recommendations on methods of formation predictive estimates of the shadow economy. This leads to the need to find effective forecasting models and techniques as a tool for management of the shadow economy. Simulation of legally unregistered processes on the basis of correlation-regression analysis allows with a high degree of reliability to evaluate the relationship between hidden profits and the dominant factors, to rank them in order of importance, and to determine the contribution of each factor to the development of shadow economic activities at the micro level

Convergence and stability analysis of kolmogorov system solutions in infinite-dimensional space

© Medwell Journals, 2017.The study studied the issues of convergence and stability of some calculation system solutions for linear differential equations, namely Kolmogorov's calculation systems in infinite-dimensional space on the basis of local integrability, non-negative coefficients and diagonal dominance properties. The conditions for operators were found with which they solve some problems of these system solution convergence and stability. On the basis of the local integrability, non-negative coefficients and diagonal dominance properties the sufficient conditions were obtained which guarantee the stability and the convergence of Kolmogorov's countable system solutions. The results of the study may be applied during the analysis of technical system various models, particularly the telecommunication system models. Besides, the results of Kolmogorov's system analysis can be used for biological system modeling. The study develops the approach to the qualitative research of Kolmogorov's systems based on the distribution of differential equation qualitative theory in infinite-dimensional spaces on Kolmogorov's systems that allowed to obtain a number of new results. Strict substantiations of the statements are presented concerning the qualitative behavior of solutions for some calculation systems of linear differential equations. One may formulate similar statements for infinite reproduction and death systems which are the particular cases of Kolmogorov's systems as the results of obtained statements

Cellular internalisation, bioimaging and dark and photodynamic cytotoxicity of silica nanoparticles doped by {Mo₆I₈}⁴⁺ metal clusters

Silica nanoparticles (SNPs) doped by hexanuclear molybdenum cluster complexes [{Mo₆X₈}L₆]n (X = Cl, Br, or I; L = various inorganic or organic ligands) have been recently suggested as materials with a high potential for biomedical applications due to both the outstanding photoluminescent properties and the ability to efficiently generate singlet oxygen upon photoirradiation. However, no studies were undertaken so far to prove this concept. Therefore, here we examined the potential of photoluminescent SNPs doped by {Mo₆I₈}⁴⁺ for such applications as bioimaging and photodynamic therapy using human epidermoid larynx carcinoma (Hep-2) cell line as a model. Our results demonstrated both: (i) significant luminescence from cells with internalised molybdenum cluster doped SNPs combined with the low cytotoxicity of particles in the darkness and (ii) significant cytotoxicity of the particles upon photoirradiation. Thus, this research provides strong experimental evidence for high potential of molybdenum cluster doped materials in such biomedical applications as optical bioimaging, biolabeling and photodynamic therapy

Using of turquoise organization’s concept to benchmark indicators of creative team management

The purpose of this study is to study the possibilities of applying the turquoise type organization model in creative industries, where there is a need for constant staff development to achieve maximum results. When analyzing the turquoise organization model, a number of factors should be taken into account, on which it relies, and also choose from a number of them those that really have a significant impact on the formation of the turquoise approach in creative industries. At a certain stage, from a non-standard creative management model, one way or another, it is necessary to return to traditional management methods while maintaining the basic principles of the turquoise organization, which can be considered as a standard. The introduction of such tools into the creative team/process management system qualitatively improves the mechanism of managerial decision-making, and also allows it to be debugged through unidirectional actions of both managers and the entire creative team. To implement the task of standardization, a universal model of quantitative assessment of qualitative indicators was developed, taking into account the dynamics of their changes. At the same time, a model was built for selecting indicators for the formation of a set of personnel characteristics in order to benchmark them relative to the level of the same characteristics of the turquoise organization, taking into account the possibility of their transversal change over time

Problems of digital library management

The article considers the organization and management of the processes of digitalization of libraries. The authors give their definition of the concept of a digital library. The paper reviews the advantages of the introduction of information and communication technologies in modern libraries, the demand for innovative digital library platforms from users. The study formulates frequent problems associated with the use of digital innovations, among which are the difficulties of managing electronic library systems. The authors note the lack of compatibility of the functionality of different platforms, which makes it difficult to transfer and adapt them from one library to another, as well as the difficulties of collecting statistics on the attendance of electronic libraries, available to both operators and users.The research paper raises the question about the development of a single standard of statistics for modern digital libraries. The study notes the necessity of creating user-friendly and understandable interfaces in electronic library applications. The problems of financing the services of digital libraries, library personnel, copyright compliance and dissemination of information about the activities of modern libraries as educational and leisure cultural centers are relevant. The authors point to the rethinking of traditional approaches to library management and the work of librarians as one of the most important tasks of organizing library systems

Research of organisation specifics of shooting process in the creation of an audiovisual product

This article presents a study of the organisation of the shooting process, taking into account the authentic features of five films by the Spanish filmmaker and photographer Carlos Saura, where the principle of “photography” was the basis for the construction of the frame. Saura made a series of films based on the flamenco culture, reflecting his experiments to establish the relationship between the beat of the music and dance and the rhythm of the set-up and movement of the camera. Carlos Saura’s work is characterised by a relationship between past and future, reality and fiction. When making a film, it is necessary to think photographically and critically, especially on the issue of national identity. The photographic act itself is an immediate transformation of the present referent into a petrified past. Elements of photography often add a strong dose of time to the movement you want to follow, but this possible action will always remain in the frame. Saura expands in a certain way what restricts the photographic act in such a way that the captured image overflows spacetime. For Saura, the relationship between photography and film becomes one of the most important components of the script in the films examined

Quadrature formulas for calculating the hadamard integral of a special form

© 2016, International Journal of Pharmacy and Technology. All rights reserved.Currently, the issues related to finding solutions to some economic problems, such as problems pertaining to the queuing systems are of great interest. These problems, in turn, result in, inter alia, the need to calculate the Hadamard integrals of a special form. The study includes the construction of an optimal quadrature formula for the approximate solution to the Hadamard integral of a special form; such formula is selected depending on the singularities of integrals. This is because of the fact that an error of the quadrature formula for a hypersingular integral is a point function of any singularity. There is a movable singularity, when parameters of the quadrature formula do not depend on the singularity’s position, and a fixed singularity, when the quadrature formula nodes are the singularity’s point functions. In this way, choice of the quadrature formula nodes depends on the choice of singularities. Assessment of the constructed quadrature formula’s error is established in the considered density class, and the order of formulas with arbitrary multiplicity nodes is optimized. The main results and conclusions are given; they were obtained for quadrature formulas of hypersingular integrals with the singularities, both movable and fixed, which can be used for solving boundary value problems, especially in simulating the fractional (or fractal) dynamic processes

Exploring the possibilities of transhumanistic risk management

The article considers the actual reflection of the transhumanistic concept in various fields of scientific knowledge. This concept has recently aroused genuine interest both because of its direction and because of its own contradictions. The discussion that has unfolded around this concept allows to evaluate all the pros and cons of the implementation of the transhumanist idea, which requires improving the physical condition of a person through the use of the most advanced technologies, among which biotechnology occupies an important place. Their use generates contextual social, economic and political problems. In this regard, it is necessary to investigate the process of emergence and development of transhumanistic risks, as well as the possibility of managing them on the basis of both traditional and original tools, taking into account the specifics of the transhumanistic approach. In the article, the authors present a study of the formation of transhumanistic risks associated with the creation and use of artificial intelligence, as well as the possibility of risk management in the transhumanistic space. The threat is increasing due to the growing globalization, interconnectedness and the speed of change in the world. These trends are generally useful, but present new challenges, including new types of transhumanistic risks associated with the use of artificial intelligence. It is more difficult to predict them than any other known risks. Conceptual options for assessing the situation developing in the transhumanistic space together represent a new vector transhumanistic risk management theory and practice development

Research of the peculiarities of enterpises՚ work organization in the intercultural space

The article is devoted to the study of the organization of the work of enterprises in the intercultural space. The authors consider the cross-cultural approach as a cross-cutting process that leads to significant changes within organizations and society and which manifests itself through interaction that functions as a generating element of the exchange of ideas and knowledge. Culture becomes the driving force of the processes taking place in international companies, where people interact freely, focusing on achieving common goals of their development, understanding their own characteristics and differences, which inevitably leads to high productivity of the organization and increased motivation of its partners.The paper considers the management of the organization’s cross-cultural space in the context of three main elements: cross-culturality, competencies and interaction in the workplace. In the course of their activities, enterprises are faced with the peculiarities of the organization of work in an intercultural space, which, as a rule, consist in the mental differences of business representatives of different cultures. In the process of interaction, difficulties may arise due to the lack of a deep understanding of the ethnic characteristics of the partner, its history, culture, etc. In this regard, the authors recommend pay attention to the quality of the acquired cross-cultural competencies of the participants of the business dialogue. Organizations should invest in the cross-cultural knowledge of their employees to increase the efficiency and productivity of internationally organized businesses.Modern organizations tend to view business processes as knowledge processes. The creation of knowledge includes its further expansion, development, improvement and application in the organization. Modern business organizations are looking for ways to create additional knowledge values through identifying, applying, and using them in a unique way, and this is a process that is part science, part art, and part pure luck. Effective management of the knowledge that people from different cultures bring, as well as the spaces in which they will interact, сontribute to strengthening the corporate image of the organization and its positioning in the international market
