The paper proposes a theoretical framework for analyzing the scientific elite, conceptualizing knowledge production as a dynamic structure shaped by internal contradictions. The scientific elite is understood not as a collection of outstanding researchers, but as a structural effect of knowledge production — a position within the scientific space that concentrates the maximum volume of ...

В работе раскрывается история появления пользовательских цифровых технологий и их распространения среди российского населения. По открытым интернет-источникам построена хронология ключевых событий с 1990-х годов. На основе репрезентативных количественных данных исследуется достижение сначала широкой, затем массовой и, в ряде случаев, всеобщей вовлеченности россиян в наиболее важные цифровые технологии.
В качестве основного источника информации для анализа вовлеченности населения ...

На протяжении XX века происходило становление и развитие социологии потребления как самостоятельной отрасли со своими теоретическими основаниями и богатыми эмпирическими изысканиями. Сегодня нарастает потребность в пересмотре и обогащении многих сложившихся социологических подходов к анализу потребительского поведения в контексте новых глобальных вызовов.

In this paper, we revisit the classic problem of a wave field on a sloping beach of an arbitrary angle and propose a general approach that allows the computation of regular solutions of the problem regardless of the angle. We use the Mellin-transform technique, reducing the problem to singular integral equations with fixed-point singularities of ...

This paper estimates the impact of the international sanctions of 2014 and 2022, as well as the food embargo, on the technical efficiency of agricultural enterprises. The assessment was carried out using panel data from agricultural enterprises specializing in dairy production in the Leningrad Region for the period 2010–2023, employing stochastic frontier analysis. It is ...

This paper examines the implications of George Herbert Mead’s conception of political institutions in the context of the problem of social change. The problem lies in how the modern governmental institution combines stability and transformative capacity. Mead’s concept of time provides a general framework for understanding change, expressed in sociality as a phase of adjustment. ...

This study provides a comprehensive assessment of the effectiveness of key instruments of Russia’s pronatalist demographic policy—specifically, the federal maternity capital program and the RUB 450,000 subsidy for partial repayment of mortgage debt—over the period 2007–2023. The central research challenge is to disentangle short-term shifts in the timing of births from long-term structural changes in ...

For the professional (in social sciences or humanities) reader David Graeber is a somewhat controversial figure. On the one hand, he is a remarkably successful foreign author in Russia: all his major books have been published in Russian, although his texts and reactions to them have been rather modestly represented in scientific journals. On the ...

The matrix profile (MP) quickly became one of the most important time series preprocessing methods when it was introduced in 2016, facilitating the solution of a wide range of time series analysis problems, in particular anomaly and pattern detection problems. The high significance has led to the emergence of various tools for MP calculating, but ...

We call a family of $s$ sets $\{F_1, \ldots, F_s\}$ a sunflower with $s$ petals if, for any distinct $i, j \in [s]$, one has $F_i \cap F_j = \cap_{u = 1}^s F_u$. The set $C = \cap_{u = 1}^s F_u$ is called the {\it core} of the sunflower. It is a classical result of ...

Generative artificial intelligence (Gen-AI) is increasingly used in higher education, yet its role in collaborative learning remains unclear. This study examines how students use Gen-AI during group lesson-planning tasks in an undergraduate education course. Drawing on Vygotsky’s sociocultural theory, we introduce the concept of “an effort space” and apply the categories of appropriate, over-, and ...

This article concerns the study of modulational instability in the rotated-modified Gardner–Whitham (rmGW) equation. This model incorporates both quadratic and cubic nonlinearities, similarly to the Gardner equation, while also retaining the fully dispersive character of the Whitham equation together with a large-scale dispersive term analogous to that in the Ostrovsky equation. Using a classical multiple-scale asymptotic expansion, we ...

The impact of state subsidies on Russia's post-Soviet dairy output remains controversial; this study provides an empirical analysis of that relationship. Using an unbalanced panel dataset of 123 dairy enterprises in the Leningrad Region spanning the period from 2010 to 2023, we employ stochastic frontier analysis to assess these relationships. The results indicate that subsidies ...

The paper is the first attempt in the Russian literature to assess returns to platform employment in the Russian labor market. The theory offers no clear predictions regarding its impact on workers’ earnings: there might be both a premium and a penalty. We distinguish three groups of workers: employees; self-employed using internet-platforms; self-employed not using ...

We investigate a special ansats that allows for an iterative solution of the constant Yang-Baxter equation. Testing this ansatz, we construct four sequences of the constant R-matrices. In each sequence the R-matrices act on the tensor squares of vector spaces of linearly growing dimensions. Each R-matrix also depends on a single complex parameter.
By analyzing the ...
