The book contains new models of bibliometric analysis based on centrality measures in network analysis, pattern analysis and stability analysis. A distinctive feature of these centrality measures is that they account for the parameters of vertices and group influence of vertices to a vertex. This reveals specific groups of publications, authors, terms, journals and affiliations ...

We develop a machine-learning approach to reproduce the behavior of two versions of the van der Pol oscillator exhibiting a subcritical Andronov–Hopf bifurcation, with or without a codimension-2 Bautin point. We construct a neural-network model that functions as a recur rent map and train it on short segments of oscillator trajectories. The results show that, ...

In this paper the structural stability of generic families of vector fields of the PC-HC class on the two-dimensional sphere is proved. A classification of these families up to moderate equivalence in neighborhoods of their large bifurcation supports is presented, based on such invariants as the configuration and the characteristic set. The realization lemma is proved. ...

It is known that for every continuous real-valued
function $f$ on the circle $\mathbb T=\mathbb R/2\pi\mathbb Z$ there exists a
change of variable, i.e., a self-homeomorphism $h$ of $\mathbb T$, such that
the superposition $f\circ h$ is in the Sobolev space $W_2^{1/2}(\mathbb T)$.
We obtain new results on simultaneous improvement of functions by a single
change of variable in relation ...

Purpose
This study aims to investigate how objective (chemical composition, processing method) and subjective (perceived fat content) milk characteristics influence taste perception.
Design/methodology/approach
A blind tasting experiment was conducted with 36 participants who evaluated six commercial milk samples (all 2.5% fat) differing in thermal processing and brand territorial coverage. Each sample was tasted twice, yielding 432 observations. Fatty ...

В статье анализируются трансформация подходов к использованию специальных финансово-экономических знаний в условиях цифровизации экономики. Рассматриваются проблемы доказывания антиконкурентных соглашений с использованием алгоритмов ценообразования, а также роль экономического анализа в делах о злоупотреблении доминирующим положением на цифровых рынках. Предлагаются пути совершенствования процессуальных механизмов интеграции экономических экспертиз. ...

This article is about the Belt and Road Initiative (BRI) of the People’s Republic of China. It concerns the projects and development associated with it in Russia (RF), the Eurasian Economic Union (EAEU), and Central-Eastern Europe (CEE). The latter primarily means 17+1 format. Based on the examples of inter-company pairings and cooperation in those regions, ...

This paper proposes Covariate-Balanced Weighted Stacked Difference-in-Differences (CBWSDID), a design-based extension of weighted stacked DID for settings in which untreated trends may be conditionally rather than unconditionally parallel. The estimator separates within-subexperiment design adjustment from across-subexperiment aggregation: matching or weighting improves treated-control comparability within each stacked subexperiment, while the corrective stacked weights of Wing et ...

This article is devoted to the phenomenon of intrinsic motivation, to understand which two models are proposed. We study how positive/negative intrinsic motivation to work (experienced utility) affects worker's individual labour supply (model I) and the amount of effort they exert (model II). In model I, we use intrinsic motivation to explain the positive/negative slope ...

In this paper, we develop a formal mathematical model aimed to explain the Dunning-Kruger effect that beginners systematically overestimate their own competence in various fields of knowledge and activity. We argue that the Dunning-Kruger effect arises from the emotional nature of confidence combined with unknown unknowns that it simply can not take into account due ...

This paper attempts to model the evolutionary theory of modernization and democratization. The model reflects the key provisions of R. Inglehart and C. Welzel's theory and provides a microfoundation for the adaptation of subjective values to the objective importances of the survival factors and the structure of the labour markets from the perspective of evolutionary ...

Many competitive environments allow for a third party to be indirectly involved by supporting one or both sides in the conflict. Such support can come from trade partners, colleagues, or allies, who can in turn benefit from a supported party's success. We use theory and an experiment to investigate how support relationships develop endogenously in ...

Context and Relevance. One of the most widely used instruments for assessing secondary traumatic stress (STS) is the Secondary Traumatic Stress Scale (STSS). This 17-item questionnaire has demonstrated strong reliability and construct validity across international studies, with consistently high internal consistency and robust psychometric performance. The present study evaluates the psychometric properties of the Russian-language ...

The study explores a psychological phenomenon of inaction inertia-avoiding action after missing a more favourable opportunity. Unlike action inertia (e.g.,sunk costs effect), inaction inertia has been less studied, particularly in economic contexts. Considering the reference dependent nature of the phenomenon, I build on the work of Kőszegi and Rabin (2006) to examine how past experiences ...

Simplified tax regimes with explicit eligibility thresholds are a common tool which reduces tax burden but distorts firms’ behavior, creating local bunching just below the threshold. However, we show that when firms have access to business splitting their responses extend far beyond the local margin. Our model demonstrates that splitting reduces local bunching but amplifies ...

In recent years, an emerging body of empirical research has shown that tax audits, in addition to recovering unpaid taxes (direct effect), increase future tax compliance (indirect or dynamic effect). This literature also suggests that updating expectations induced by audit experience plays an important role in explaining this indirect effect. However, exactly how taxpayers form ...

While the emerging empirical literature shows that collateral tax sanctions (CTSs) - such as driver’s license suspensions or passport denials - appear to be effective instruments to enforce tax debt collection, there are still few theoretical arguments to explain why. In this paper, I model enforcement of tax debt collection and provide a new rationale for why it could ...

We study the application of factor investing in the market for real estate (REITs). The analysis of traditional factor strategies, such as momentum, value, size and profitability, reveals their unstable and atypical behavior in comparison to the equity market, however, there is a strong momentum effect in the factor strategies. We propose a new dynamic ...

В данной статье рассматривается реакция российских предприятий обрабатывающей промышленности на ужесточение экономических санкций с акцентом на период после 2022 года. Хотя санкции в целом негативно сказываются на экономическом росте и эффективности деятельности компаний, есть некоторые свидетельства того, что они также могут подталкивать компании к инновациям, а негативный эффект преодолевается при помощи адаптации компании. Исследование заполняет ...

Innovation has long been at the center of debates in economics, management, and organizational studies. However, innovation is never free of uncertainty and risk. Every act of innovation implies a departure from established paths and a willingness to embrace the unknown. From the beginning it's never clear if there is an audience which appreciates the ...
