The development of musical abilities, including absolute pitch, musical memory, rhythm sense, and musicality, at a high degree is determined by a hereditary component (up to 68 %). The studies implementing a genome-wide linkage and association approach to musical aptitude have revealed more than 100 genetic loci. This spectrum is comprised of the genes encoding ...

Compared to other African countries, Ghana is known as a relatively stable democracy. However, there are various forms of social, political, ethnic, and religious instability that have persisted
in Ghana for many decades and posed some risks for the indigenous Ghanaian diaspora. These instabilities are typically categorized as either inter- or intra-ethnic conflicts. The article gives
an ...

Recently, West Africa is represented in the research literature as the epicenter of socio-political instability. That is most relevant for such countries asMali, Nigeria or Burkina Faso. However, it is worth saying that, despite a number of factors that could lead to potential destabilization in Ghana, the country has been characterized in recent years by a ...

The problem of the remote employment rate in Russia and its determinants is considered. Remote employment is poorly represented in the results of even large-scale sample observations by Russian State Statistical Service, which does not allow using traditional statistical tools for modelling its development potential. The problem can be solved by balancing the data by ...

The platform economy is a global phenomenon with a huge social and financial outcome comparable to the Industrial Revolution. Currently, no nation-state worldwide possesses an established and harmonized regulatory practice for digital platforms. This circumstance presents a distinct challenge for public governance, particularly concerning the allocative function and the ability to control externalities for the ...

The article deals with some approaches to solving convex problems of the min-min type with smoothness and strong convexity in only one of the two groups of variables. It is shown that the proposed approaches based on Vaidya’s method, the fast gradient method, and the accelerated gradient method with variance reduction have linear convergence. It ...

Purpose. The paper aims to identify personality types and traits of project managers in comparison with functional managers. Based on a review of current research, the most frequently mentioned as dominant MBTI personality types are identified. Differences in personality types and personality characteristics are studied using comparative qualitative analysis. The personality diversity in the two ...

This paper is devoted to modeling the probability of default of Russian banks in 2015–2020. There are relatively few studies on defaults of Russian banks after 2015, and our work intends to partly fill this gap. The purpose of this research is to determine the main variables which significantly impact the risk of default of ...

Building upon the complexity theory, we explore the interaction effects of the development of key digital information and communication technologies (ICTs) at the national level on a country's sustainability performance. By the means of the fuzzy-set Qualitative Comparative Analysis on a sample of 77 countries, we show that 1) a country's ICT profile matters for ...

This paper introduces several novel strategies for multi-step-ahead prediction of chaotic time series. Introducing a concept of “generalized z-vectors” (vectors of nonsuccessive time series observations) makes it possible to generate sets of possible prediction values for each point we are trying to predict. +rough examining these sets, uni8ed predictions are calculated, which are in turn ...

Введение. Спрос на медицинские услуги неодинаков для различных групп населения. Определение межгрупповых различий в использовании системы здравоохранения способствует выявлению диспропорций в доступности медицинской помощи. Для исследования поведения разных групп населения в системах здравоохранения используется модель Андерсена, являющаяся теоретическим базисом данной работы.
Цель исследования: определить группы населения РФ, которые более склонны обращаться за помощью в медицинские организации, и ...

In most of current papers devoted to the analysis of protest-repression nexus, the research
design misses the dynamic nature of this nexus, which seems methodologically incorrect. The
analysis of the dynamics allows us to identify the role of various factors influencing the course of
this conflict. The variety of different dynamics of the number of protesters and the ...

Prior research suggests that synergies between deep and shallow technologies could create unprecedented capacity to achieve sustainable development. However, there is little understanding if these synergies are already achieved and how different technologies work together on a country level to enable its sustainable development. We respond to this question starting from the contingency theory and adopting a configurational perspective ...

We investigate fluctuations of vorticity inside a coherent vortex generated by the inverse energy cascade in two-dimensional turbulence. Temporal and spatial correlations can be characterized by the pair correlation function. The interaction of fluctuations leads to a nonzero third moment of vorticity. We analyze the
pair correlation function and the third moment using a model in ...

In this paper, we study a generalized construction of (2m, 2m)-functions using monomial and arbitrary m-bit permutations as constituent elements. We investigate the possibility of constructing bijective vectorial Boolean functions (permutations) with specified cryptographic properties that ensure the resistance of encryption algorithms to linear and differential methods of cryptographic analysis. We propose a heuristic algorithm ...

It is well known that an inverse turbulent cascade in a finite ($2 \pi \times 2 \pi$) two-dimensional periodic domain leads to the emergence of a system-sized coherent vortex dipole. We report a numerical hyperviscous study of the spatial vorticity profile inside one of the vortices. The exciting force was shortly correlated in time, random ...
