THE COMPARATIVE ANALYSIS OF THE CULTURAL, COMMON-CULTURAL, SOCIOCULTURAL, CULTUROLOGICAL, MULTICULTURAL, CROSS-CULTURAL COMPETENCIES DEFINITIONS

Cultural diversity and cultural pluralism are integral components of a competent approach to training a qualified specialist in the modern educational process that allows effective interaction in the process of the cross- and communication. In this context, active expansion received close in meaning, but different in their essence and purpose concepts, namely: common cultural, sociocultural, culturological, multicultural, cross-cultural and cultural competencies. The article presents a comparative analysis of these terms, taking into account aspects crucial for their differentiation and important for the contextual application. To synthesize the scientific thought of the work, the recent years' sources in the field of competent interrelations of individuals and groups of different cultures were thoroughly analyzed, the said concepts of competence were separated from each other depending on the sphere of application. Each of the competencies identifies the knowledge, skills and experience, as well as the personal characteristics of an individual, the acquisition and development of which are essential for the formation of one or another competence of modern specialist in the light of globalization processes. It should be emphasized that cultural competence comes in the form of meta- competence as a conditionally sufficient measure of socialization and interculturalism of an individual. This allows them to independently understand and freely use at their discretion all the acquired competencies and skills concerning socio-cultural and social, institutional and conventional norms and regulators of behaviour in the process of mobile social communication, including in different languages. Identifying the different aspects of the mentioned competencies will allow us to differentiate the stated terms in the context of the educational process reformation in Ukraine and the qualified training of future specialists. Summarizing the results of the study, the article highlights the distinctive features of competencies, and the meaningful definitions emphasize their essence: Common cultural competence is based on the knowledge of the characteristics of the society culture, implies the possession of communication skills adopted in a particular society and as a key competence includes sociocultural and culturological competencies. Interpersonal interaction with the representatives of another culture reflects a level of competence, also called intercultural and communicative competence. Multicultural competence allows finding those behaviours that promote mutual trust and effective interethnic interaction, eliminate intolerant attitude towards people of different skin colour, different language, culture or other values. Cross-Cultural competence implies an awareness of the differences (ideological, ceremonial, cult or traditional ones) inherent in a particular culture.

Voice biometrics security: Extrapolating false alarm rate via hierarchical Bayesian modeling of speaker verification scores

How secure automatic speaker verification (ASV) technology is? More concretely, given a specific target speaker, how likely is it to find another person who gets falsely accepted as that target? This question may be addressed empirically by studying naturally confusable pairs of speakers within a large enough corpus. To this end, one might expect to find at least some speaker pairs that are indistinguishable from each other in terms of ASV. To a certain extent, such aim is mirrored in the standardized ASV evaluation benchmarks, for instance, the series of speaker recognition evaluation (SRE) organized by the National Institute of Standards and Technology (NIST). Nonetheless, arguably the number of speakers in such evaluation benchmarks represents only a small fraction of all possible human voices, making it challenging to extrapolate performance beyond a given corpus. Furthermore, the impostors used in performance evaluation are usually selected randomly. A potentially more meaningful definition of an impostor — at least in the context of security-driven ASV applications — would be closest (most confusable) other speaker to a given target.We put forward a novel performance assessment framework to address both the inadequacy of the random-impostor evaluation model and the size limitation of evaluation corpora by addressing ASV security against closest impostors on arbitrarily large datasets. The framework allows one to make a prediction of the safety of given ASV technology, in its current state, for arbitrarily large speaker database size consisting of virtual (sampled) speakers. As a proof-of-concept, we analyze the performance of two state-of-the-art ASV systems, based on i-vector and x-vector speaker embeddings (as implemented in the popular Kaldi toolkit), on the recent VoxCeleb 1, and 2 corpora, containing a total of 7365 speakers. We fix the number of target speakers to 1000, and generate up to N=100,000 virtual impostors sampled from the generative model. The model-based false alarm rates are in a reasonable agreement with empirical false alarm rates and, as predicted, increase substantially (values up to 98%) with N=100,000 impostors. Neither the i-vector or x-vector system is immune to increased false alarm rate at increased impostor database size, as predicted by the model.

Topological string entanglement

We investigate how topological entanglement of Chern-Simons theory is captured in a string theoretic realization. Our explorations are motivated by a desire to understand how quantum entanglement of low energy open string degrees of freedom is encoded in string theory (beyond the oft discussed classical gravity limit). Concretely, we realize the Chern-Simons theory as the worldvolume dynamics of topological D-branes in the topological A-model string theory on a Calabi-Yau target. Via the open/closed topological string duality one can map this theory onto a pure closed topological A-model string on a different target space, one which is related to the original Calabi-Yau geometry by a geometric/conifold transition. We demonstrate how to uplift the replica construction of Chern-Simons theory directly onto the closed string and show that it provides a meaningful definition of reduced density matrices in topological string theory. Furthermore, we argue that the replica construction commutes with the geometric transition, thereby providing an explicit closed string dual for computing reduced states, and Rényi and von Neumann entropies thereof. While most of our analysis is carried out for Chern-Simons on S3, the emergent picture is rather general. Specifically, we argue that quantum entanglement on the open string side is mapped onto quantum entanglement on the closed string side and briefly comment on the implications of our result for physical holographic theories where entanglement has been argued to be crucial ingredient for the emergence of classical geometry.

Chemical Bonding from the Statistics of the Electron Distribution.

An introduction to the theory of chemical bonding from the point of view of the statistics of the electron distribution is presented. When atoms bind to form a molecule, their originally fixed number of electrons ceases to be a well-defined observable, and this implies that their in-the-molecule electron populations fluctuate. If a chemically meaningful definition of an atom in a molecule is assumed, the probabilities of finding a given number of electrons in each of the atoms comprising the molecule can be computed. We show in this review how the complete electron distribution function (EDF) can be used to reconstruct the basic concepts and quantities used in chemical bonding without recourse to the orbital paradigm. From the statistical point of view, which inherits Born's probabilistic interpretation of quantum mechanics, a set of atoms are bonded when their electron populations are mutually dependent. We quantify this statistical dependence by the cumulant moments of the EDF, which provide a consistent description of both two- and multi-center bonding. Particular attention is paid to building EDFs from model wavefunctions. With this, a simple bridge with orbital thinking is built. The statistical interpretation allows to easily classify all possible bonds of a given kind. We show that there are vast unexplored territories that should receive due consideration. Although building EDFs from models is easy and very instructive, the contrary is considerably more difficult. Recipes to extract chemical information from computed EDFs are also reviewed and, in all the cases, simple toy systems are used to show how the methodology works, allowing non-experts to follow easily the presentation.

Existence of special rainbow triangles in weak geometries

Abstract We show that, in any ordered plane with a symmetric orthogonality relation which allows for a meaningful definition of acute and obtuse angles, in which all points are colored with three colors, such that each color is used at least once, there must exist both an acute triangle whose vertices have all three colors and an obtuse triangle with the same property. We also show that, in both a geometry endowed with an orthogonality relation, in which there is a reflection in every line, in which all right angles are bisectable, which satisfies Bachmann’s Lotschnittaxiom (the perpendiculars raised on the sides of a right angle intersect), and in plane absolute geometry, in which all points are colored with three colors, such that each color is used at least once, there exists a right triangle with all vertices of different colors.

Development of a conceptual model of adaptive management of human capital reproduction of industrial enterprises

The object of research is the adaptive management of the human capital reproduction of industrial enterprises. It is established that the management of the human capital reproduction of Ukrainian industrial enterprises is characterized by a complex of problems. Among them – a long lag from world standards for labor costs, which leads to a gap in the characteristics of human capital, hyperturbulence of the business environment. It is determined that the lack of scientific research in the field of adaptive management of the human capital reproduction enhances the depth of existing practical problems and makes it impossible to form an innovative economy in the country. This required the formation of a conceptual model of appropriate management.The expediency of the formation of adaptive control by the characteristics of adaptation when improving its meaningful definition is proved. The principal aspects of the new design, the “adaptation” concept are: continuity of changes, process as an activity, the interaction of the business environment and the system, the response to changes in the general environment, incorporation into the result of active and passive behavior of enterprises, the strategic context of adaptive changes. Based on the reaction and the time of its implementation, the main types of adaptive processes are identified.The elements of adaptive control are defined: signal, change, management cycle, control result. Based on the integration of these elements and the content context of the human capital reproduction management system, the concept of “adaptive management of the human capital reproduction of industrial enterprises” is constructed. The stages of such management and their tasks are determined. The scheme of the conceptual model of adaptive management of the human capital reproduction of industrial enterprises is formed.Based on a formal assessment of the structure and logic of building the model, its essential properties and the link, the conclusion about model verification is scanned.The practical implementation of the developed proposals allows to provide a quick and targeted response of enterprises to changes in the business environment regarding the adjustment of the characteristics of human capital. Unlike similar well-known models, the proposed format creates the basis for determining adequate directions of transformation of the reproduction process.

Epidemiology of Asthma in Children and Adults.

Asthma is a globally significant non-communicable disease with major public health consequences for both children and adults, including high morbidity, and mortality in severe cases. We have summarized the evidence on asthma trends, environmental determinants, and long-term impacts while comparing these epidemiological features across childhood asthma and adult asthma. While asthma incidence and prevalence are higher in children, morbidity, and mortality are higher in adults. Childhood asthma is more common in boys while adult asthma is more common in women, and the reversal of this sex difference in prevalence occurs around puberty suggesting sex hormones may play a role in the etiology of asthma. The global epidemic of asthma that has been observed in both children and adults is still continuing, especially in low to middle income countries, although it has subsided in some developed countries. As a heterogeneous disease, distinct asthma phenotypes, and endotypes need to be adequately characterized to develop more accurate and meaningful definitions for use in research and clinical settings. This may be facilitated by new clustering techniques such as latent class analysis, and computational phenotyping methods are being developed to retrieve information from electronic health records using natural language processing (NLP) algorithms to assist in the early diagnosis of asthma. While some important environmental determinants that trigger asthma are well-established, more work is needed to define the role of environmental exposures in the development of asthma in both children and adults. There is increasing evidence that investigation into possible gene-by-environment and environment-by-environment interactions may help to better uncover the determinants of asthma. Therefore, there is an urgent need to further investigate the interrelationship between environmental and genetic determinants to identify high risk groups and key modifiable exposures. For children, asthma may impair airway development and reduce maximally attained lung function, and these lung function deficits may persist into adulthood without additional progressive loss. Adult asthma may accelerate lung function decline and increase the risk of fixed airflow obstruction, with the effect of early onset asthma being greater than late onset asthma. Therefore, in managing asthma, our focus going forward should be firmly on improving not only short-term symptoms, but also the long-term respiratory and other health outcomes.

POLYSEMICITY OF THE TERMS «DEMURRAGE» AND «DETENTION» APPLIED IN THE PRACTICE OF LINER AND TRAMP SHIPPING

Purpose. The presented study aims to systematize the definition of the terms «demurrage» and «detention», which are used in the theory and practice of maritime transportations, but are characterized by different meaningful definition when used in liner and tramp shipping, which requires the need for a comparative analysis. Methodology. For the stated comparative analysis, the applied information sources allowed to determine the specificity of the terms «demurrage» and «detention» both at the scientific level and at the level of practical implementation. Findings. The authors proved that despite their synonymous character, the terms «demurrage» and «detention» have fundamental differences when used in transportation contracts for the vessels of liner and tramp shipping. Taking into account the specific conditions of these organizational forms of shipping, the terms, the meaningful interpretation of which are the object of the study, have a different object of accrual, the procedure for substantiating the value of the corresponding rates and the procedure for calculating the total amount. Originality. The authors for the first time carried out a study in the context of two forms of organization of maritime transport (tramp and linear) and established the semantic features of the marine terms «demurrage» and «detention». Practical value. The commercial practice of transport companies, in particular shipping ones, is closely connected with technical, technological, organizational, legal, economic and even linguistic issues. The last aspect concerns the role of the accuracy of understanding of the terms by the parties to the transportation contracts concluded by shipping companies (liner and tramp shipping) with counterparties, since it is the responsibility of a material nature that follows from them. Clear interpretation of the terms is crucial to prevent possible disputes regarding the relevant payments. Uncertainty, which is currently present in scientific publications and literary sources of practical nature, leads to a free interpretation and substitution of the analyzed terms with each other without a clear distribution of the parties' responsibility in different forms of shipping.

Meaningful and feasible composite clinical worsening definitions in paediatric pulmonary arterial hypertension: An analysis of the TOPP registry

BackgroundComposite clinical worsening (cCW) outcomes might allow measurement of disease progression in paediatric pulmonary arterial hypertension (PAH). This TOPP registry analysis investigated three cCW outcomes and their predictive strength for lung transplantation/death. MethodsPatients ≤17 years with idiopathic/familial PAH or PAH-associated congenital heart disease diagnosed ≤3 months before enrolment were included. cCW outcomes included the following variables at enrolment and/or follow-up: all-cause death, PAH-related hospitalisation, lung transplantation, atrial septostomy (cCW1, 2 and 3), WHO FC deterioration, intravenous/subcutaneous prostanoids initiation, syncope (cCW2,3) and occurrence/worsening of ≥2 PAH symptoms (cCW3). The predictive value of CW (excluding transplantation and death) to transplantation or death was assessed. Predictive values of each cCW for lung transplantation/death were analysed by Cox proportional hazards models. ResultsFrom 255 patients, first-event rate/100 person-years (95% CI) were cCW1: 23.1(19.3,27.6), cCW2: 43.6(37.6,50.6), and cCW3: 46.3(40.0,53.7) with PAH-related hospitalisation as the most frequent first event in each. The cCW definitions comprised from endpoints (excluding transplantation and death), were associated with higher risk [hazard ratio (95% CI)] for lung transplantation/death [4.23(2.27,7.91), 3.25(1.65,6.39), 2.74(1.41,5.34), respectively]; individual parameters with higher risks were WHO FC deterioration [3.49(1.47,8.29)], PAH-related hospitalisation [2.62(1.32,5.20)] and occurrence/worsening of ≥2 PAH symptoms [2.13(1.02,4.45)]. ConclusionsThese data support the use of cCW outcomes in paediatric PAH research. WHO FC deterioration, PAH-related hospitalisation, occurrence/worsening of ≥2 PAH symptoms may be important for risk assessment during clinical management.

Implications of the 2017 AAP Clinical Practice Guidelines for Management of Hypertension in Children and Adolescents: a Review.

To evaluate the impact of the 2017 American Academy of Pediatrics Clinical Practice Guideline (2017 AAP CPG) for Screening and Management of High Blood Pressure in Children and Adolescents. The 2017 AAP CPG had several significant changes compared to the 2004 Fourth Report. This review will focus on the emerging evidence from the first studies to apply the 2017 AAP CPG and the simplified table it contains on the overall prevalence of HTN and on recognition among children and adolescents at a higher cardiovascular risk. Recent evidence suggests that use of the 2017 AAP CPG will result in an overall increase in prevalence of HTN, particularly in youth who are obese or who have other cardiovascular risk factors. The change in prevalence likely differs based on sex, age, and height. The ability for the 2017 AAP CPG to detect an association with hypertension and target organ damage requires further study. Continued study is required to assess long-term implications of the 2017 AAP CPG with the goal of a more meaningful HTN definition in the young.

Границы искусства в древней и новой материальной культуре

The article discusses the meaningful definition of the concept of art for objects of material culture and the possibility of its expansion to other kinds of art. Each subject might be considered as a complex of features, some of them may bear artistic values. It turns out that for art related features deviations from the cultural accepted standard are crucial. The object with a certain number of deviations from anticipated standard would be most likely perceived as an art object. Thus we assume that the field of art is on the one hand limited by the standard, on the other hand, by such degree of deviation that goes beyond the comprehension of an ordinary culture bearer. With some restrictions this principle can be extended to other areas of human activity.

Smart Furniture as a Component of a Smart City—Definition Based on Key Technologies Specification

There are dozens of definitions of smart furniture with meanings that vary greatly. Thus, the aim of this paper is to provide an exact definition of the phrase “smart furniture” based on literature and patent analysis. Why a definition? Because by providing a good definition, we have a statement that captures the meaning, the use, the function, and the essence of a term or a concept and allows the impacts on stakeholders to be described. A literature search was undertaken between 20 July 2018 and 31 August 2018, and the databases searched included SCOPUS, Web of Science, and IEEE Xplore (1998-2017), which were searched by keywords that included the phrase “smart furniture.” Patent searching was performed in the ESPACENET database, where 226 articles from scientific databases and 737 patent applications were examined. After the application of strict criteria, we obtained 23 articles and six patents containing meaningful definitions of smart furniture. Based on the results, smart furniture should be defined as designed, networked furniture that is equipped with an intelligent system or is controller operated with the user's data and energy sources. Smart furniture needs to have the ability to communicate and anticipate a user's needs using a plurality of sensors and actuators inside the user's environment, resulting in user-adapted furniture. The research results and discussion presented in this paper are based on the recognition that the smart furniture research has great policymaking, technological, and economy potential while contributing to the user's wellbeing and Quality of Life (QoL). This paper indicates that the collaboration between the ICT and social-economic research has to be initiated and consolidated in a sustainable way or in an environment that satisfies the needs expressed by the user.

Assessment of the social component of the effectiveness of the transition to alternative energy sources

Energy conservation is a key focus of the green economy. The correct energy conservation policy of a country can significantly increase its competitiveness of the national economy. The aim of the article is a meaningful definition of the energy saving process, a qualitative and quantitative assessment of the social component of the effectiveness of the transition to alternative energy sources. Objective: study of one of the promising measures of energy conservation policy - attracting renewable energy sources in economic activity. General scientific methods are used: system analysis - to determine the features of the development of energy saving in Ukraine, comparative analysis to formalize the cause-effect relationships of the studied factors of the influence of renewable energy sources on the country's economic activity. It is determined that energy saving should be understood as the process of ensuring the rational use of energy resources in economic activity with minimizing environmental damage through the implementation of a set of measures (regulatory, scientific, practical, financial, economic, organizational, technical, informational, educational and innovative). The classification of measures in the field of energy conservation is systematized. In order to stimulate the development of "green" energy in the regions, the need is substantiated, together with the calculation of economic and environmental effects, to assess the social effect of the introduction of alternative energy. Conclusions: the proposed approach for calculating the social effect of the use of renewable energy sources is based on qualitative and quantitative characteristics that affect social changes in society during the transition to renewable energy sources. The proposed formula for assessing the social effect is of significant economic importance and can be used to justify the effectiveness of the development of renewable energy.

RISK ECONOMY

The article is devoted to the theoretical substantiation of a new social paradigm – risk economy. The current stage of society development and the economy is characterized by a critical increase in financial, technological and technological, political and economic, geo-economic and other uncertainties. It is impossible to understand their ontological nature and reveal the phenomenological specificity without a meaningful definition of the current stage of development of the economic system of society. The article consistently revealed the characteristics of current society, which allowed the author to present a new political and economic concept that characterizes the current stage of development of society and the economy – the risk economy. The risk economy is an economy of high-tech and knowledge-intensive industries, characterized by the highest degree of political, economic, technological, financial and environmental uncertainties and risks. These risks are becoming comprehensive, many of them are in principle unpredictable, and their possible negative consequences could lead Humanity to a global catastrophe. Understanding the nature of risk economics is critically important for developing effective political and economic mechanisms to counter these risks.

Importance of the heart vector origin point definition for an ECG analysis: The Atherosclerosis Risk in Communities (ARIC) study

AimOur goal was to investigate the effect of a global XYZ median beat construction and the heart vector origin point definition on predictive accuracy of ECG biomarkers of sudden cardiac death (SCD). MethodsAtherosclerosis Risk In Community study participants with analyzable digital ECGs were included (n = 15,768; 55% female, 73% white, mean age 54.2 ± 5.8 y). We developed an algorithm to automatically detect the heart vector origin point on a median beat. Three different approaches to construct a global XYZ beat and two methods to locate origin point were compared. Global electrical heterogeneity was measured by sum absolute QRST integral (SAI QRST), spatial QRS-T angle, and spatial ventricular gradient (SVG) magnitude, azimuth, and elevation. Adjudicated SCD served as the primary outcome. ResultsThere was high intra-observer (kappa 0.972) and inter-observer (kappa 0.984) agreement in a heart vector origin definition between an automated algorithm and a human. QRS was wider in a median beat that was constructed using R-peak alignment than in time-coherent beat (88.1 ± 16.7 vs. 83.7 ± 15.9 ms; P < 0.0001), and on a median beat constructed using QRS-onset as a zeroed baseline, vs. isoelectric origin point (86.7 ± 15.9 vs. 83.7 ± 15.9 ms; P < 0.0001). ROC AUC was significantly larger for QRS, QT, peak QRS-T angle, SVG elevation, and SAI QRST if measured on a time-coherent median beat, and for SAI QRST and SVG magnitude if measured on a median beat using isoelectric origin point. ConclusionTime-coherent global XYZ median beat with physiologically meaningful definition of the heart vector's origin point improved predictive accuracy of SCD biomarkers.

Quantifying Reasonable Doubt

This article contributes in three ways to the prior literature on the reasonable doubt standard. First, it synthesizes the insular strands of historical, economic, jurisprudential, and doctrinal scholarship on reasonable doubt. Second, it advances a conception of the criminal standard of proof designed to avoid the various problems affecting earlier attempts to devise meaningful definitions of reasonable doubt. The definition proposed is that “reasonable doubt” be the standard of proof which minimizes the aggregate subjective expected social cost of false conviction and false acquittal. Judicial pronouncements of Blackstonian ratios (for example, that it is better that ten guilty go free than one innocent be convicted) are interpreted as judicial estimates of these variables, from which efficient reasonable doubt standards may be calculated. It is urged that courts adopt the precise numerical measures of certainty in jury instructions (for example, that a juror should only vote to convict if he is more than x% certain of the defendant’s guilt). Judicial pronouncements of Blackstonian ratios are collected from the caselaw of all fifty states and federal courts to encourage practitioners to test the refined conception in their jurisdiction.

Atomic-pair theorem for universal matrix representatives of molecules and atomic clusters in non-relativistic Born-Oppenheimer approximation

The mathematical underpinnings of a universal atomic-pair based approach to ab initio calculations of the electronic wave functions and energies of molecules and other atomic clusters are reported in non-relativistic Born-Oppenheimer approximation. The general approach utilizes the closure of an orthonormal (Eisenschitz-London) outer product of atomic spectral eigenstates to support totally antisymmetric aggregate eigenstates in the absence of explicit term-by-term atomic-product basis antisymmetry. Meaningful definitions of atomic-pair interaction operators and of their corresponding universal matrix representatives on the atomic product basis are obtained in this way for calculations on physical and chemical aggregates. Symmetric-group-based permutation-symmetry methods for partitioning of aggregate Hamlitonian matrices, performed to date by unitary transformations to remove unphysical “non-Pauli” states after aggregate Hamiltonian matrix construction, are supplemented here with a new two-step procedure. The new approach, which combines explicit antisymmetrization of atomic pair matrices with unitary transformation of aggregate Hamiltonian matrices, is described here in complete mathematical detail. Conditions are established from the new development under which enforcement of pairwise-atomic antisymmetry alone can be sufficient for calculations of electronic energies, providing an efficient approach for practical applications, as well as long-absent theoretical support for related semi-empirical and ad hoc methods widely employed in computational molecular physics and quantum chemistry. An exact expression is obtained for total electronic energies from the solution of the Schrödinger equation in the universal form of sums over pairwise-atomic interaction energies uniquely defined within a molecule in the absence of subjective additional conditions. Wigner rotation matrices are employed to orient pairs of interacting atoms within an aggregate in the implementation of the approach, requiring calculations of the universal pair interaction matrices as functions of radial separations only. Such information can be obtained once and for all from molecular diatomic calculations and retained for subsequent use, avoiding repeated evaluations of the electronic integrals commonly required in conventional variational determinations of accurate potential energy surfaces. Diagonalizations of large Hamiltonian matrices are avoided in favor of optical potential, Krylov-Lanczos, and previously described Stieltjes-Techebycheff methods in determination of aggregate Schrödinger eigenspectra.
