Published: December 2024

Against the backdrop of the development of theoretical and practical interest in network forms of implementing the country’s innovation policy, the problem of improving the methodological basis for assessing the predictive performance of clusters remains poorly developed. Since clusters act as independent mesoeconomic systems, the assessment of the specifics of each model of such a system should take into account a whole range of socio-economic, geopolitical, and sectoral parameters. The purpose of the article is to present the results of a comprehensive situational modeling of three organizational network structures: autonomous production in the Perm region (model 1), production within a technology park (model 2), and production within an industrial cluster (model 3). The selection of models was carried out by analogy with the already implemented model of the Photonics cluster. The research methodology was the use of the author’s methodology for assessing institutional network potential. The research method was an assessment of the characteristics of the analyzed models with the help of independent experts from the EFQM group in Russia. Because of the simulation, it was found that for model 3 (production within an industrial cluster), the expected synergistic effect is underestimated by 21.17% on average; that is, quantitative indicators have a growth potential of 20–22%, respectively. This indicates an underestimation of the influence of the institutional environment or a higher likelihood of synergistic effects and the stability of the interaction system. The results of the study allowed us to formulate the conclusion that the completeness of the realizability of the interests and goals of the participants in each cluster model depends on the density of its institutional environment. The density of the institutional environment is a basic component for realizing network potential and determining institutional effectiveness.

Published: December 2024

The article analyzes the results of the execution of the federal budget of the Russian Federation in 2023. The relevance and novelty of the study are associated with changes in the values of indicators of the federal budget and the budgets of centralized funds of the Russian Federation in comparison with the planned indicators mentioned in laws. This paper presents a comparative description of the execution of the federal budget for the 2022–2023 fiscal years, accompanied by an analysis of the dynamics of the selected indicators. The study was conducted more through structuring and comparative analysis. Thanks to this, wide ranges of indicators were studied, which were analyzed both in planned and actual terms. The functions of centralized funds are defined, and their characteristics are given depending on the functions. Key trends in receipts to the centralized funds of the Russian Federation were identified. During the study, it was established that the execution of the federal budget in 2023 occurred in accordance with the target parameters of the structural balance approved in the budget law. The execution of the federal budget of the Russian Federation for 2023 was studied by grouping sources for oil and gas and non-oil and gas revenues. It was determined that the volume of non-oil and gas revenues at the end of 2023 exceeded the parameters laid down during the formation of the budget law. The federal budget deficit was established, but trends towards its reduction were observed. It is noted that the execution of budgets of centralized funds of the Russian Federation in 2023 is also characterized in a positive way. It was revealed that in 2024, an increase in the volume of receipts from centralized funds and the federal budget of the Russian Federation is predicted.
Experimental observations from cyclic cone penetrometer testing in clay
Authors: Mani Senthen Amuthan , O’Loughlin Conleth , Bienen Britta , Bransby M. Fraser
Published: December 2024

Cone penetrometer tests involve a monotonic penetration and extraction phase, sometimes with pauses to measure the dissipation of excess pore pressure. This paper explores the merit of including cyclic episodes to measure the change in tip and sleeve resistance during cycling. Tests were carried out in a geotechnical centrifuge to explore how factors such as over consolidation, cyclic amplitude and time affect the cyclic response of kaolin clay. The data indicate that the cone sleeve mobilises the remoulded undrained shear strength during the initial penetration, but that with continued cycling, the mobilised interface shear strength reduces to around one-third of the remoulded undrained shear strength before increasing. The initial reduction is considered to be due to consolidation around the cone sleeve, whereas the subsequent increase is attributed to consolidation-induced strength hardening. The time scales associated with these competing processes were seen to be a function of the cyclic amplitude, as this controlled the amount of shear strain accumulation in a given time period. The findings suggest that cyclic cone penetrometer tests may be a convenient means of gathering data for input to geotechnical design of problems where the cyclic response at the clay/structure interface is of interest.

PRAGMATIC MARKEDNESS OF THE ADJECTIVE ЛУЧШИЙ IN MODERN SPEECH PRACTICES
Authors:   Immanuel Kant Baltic Federal University, Dudurich O.V.
Published: December 2024

The study aims to reveal the functional features of the superlative adjective «the best» in different types of modern discourse. By using the methods of functional-semantic and pragmatic analysis we have established that the use of the adjective in the context of high evaluation in the speech acts «You are the best!» leads to loss of semantization and actualization of the pragmatic component of the word. The use of such statements in media headlines is mainly attributed to the word «the best» belonging to the motivational vocabulary, reflecting the system of values inherent in a society based on the principle of individualistic competition.

Published: December 2024

This article examines recent transformations in cultural discourse, particularly concerning issues of the creative economy and its impact on the contemporary Brazilian art market, using SP-Arte as a case study. The analysis highlights the integration of cultural industries into new processes of subordination and assimilation, characterized by the aestheticization of the social sphere. Grounded in a literature review and data analysis, the research explores the concept of the "creative industry" and investigates recent production modes at SP-Arte, emphasizing its "biennialization" features—such as curated sectors and educational functions—and its internationalization strategies. The study examines the interrelation between culture and economy, contributing to a deeper understanding of the transformations within the contemporary art market and cultural policies in Brazil. Additionally, the article underscores challenges related to the exclusion of smaller agents and the gentrification of urban spaces that host services and businesses tied to the art system in São Paulo. The research provides theoretical tools for analyzing similar cultural events, broadening the debate on the interaction between cultural practices, market dynamics, and public policies.
Configurações urbanas, fatores socioeconômicos e conforto térmico em São José do Rio Preto, SP
Authors: Menegaldo Vanize , Masiero Érico
Published: December 2024

This study investigates the relationship between environmental comfort and urban socio-spatial settings in the city of São José do Rio Preto. The method consists of the analysis and thermal characterization of four urban areas in the city: two in areas characterized by high building standards and two in areas of special social interest. Campaigns to collect data on temperature and air humidity were carried out simultaneously, using reports from passersby about their perception and satisfaction with the thermal environment. The Physiological Equivalent Temperature (PET) climatic index was calculated, and reports on perception and satisfaction with the thermal environment were statistically analyzed in terms of the physical characteristics of the adopted urban areas. The contributions may lead to reflections on possible relationships between socioeconomic factors and urban thermal comfort conditions. Questions related to the Sky View Factor, the direction and speed of the wind, and the availability of outdoor areas are decisive for the variation of PET and user satisfaction reports on the thermal environment in the four urban areas. The analysis and discussion of this study reaffirmed the importance of considering climate issues in urban planning. To achieve this, the aim is to contribute with analyses that can help formulate proposals for future improvements.

Authors: Karacif Kubilay , Hasırcı Hasan , Candemir Duygu
Published: December 2024

Bu çalışmada, uygulanan suni yaşlandırma, doğal yaşlandırma ve kriyojenik ısıl işlemlerinin A-360 alüminyum alaşımının korozyon ve sertlik özelliklerine etkileri incelenmiştir. Yaşlandırma öncesi çözeltiye alma işlemi 560 ℃ sıcaklıkta, suni yaşlandırma işlemi 190 ℃ sıcaklıkta, kriyojenik işlem ise -140 ℃ sıcaklıkta uygulanmıştır. Kriyojenik işlem süresi 8 ve 16 saat olmak üzere iki farklı sürede uygulanmıştır. Farklı ısıl işlemlerin uygulandığı numunelerin korozyon özellikleri %3,5 NaCl ortamında potansiyodinamik korozyon testleri ile belirlenmiştir. Numunelerin sertlik incelemeleri Vickers yöntemi ile yapılmıştır. Mikroyapı incelemelerinde optik mikroskop kullanılmıştır. Korozyon test sonuçlarına göre; uygulanan yaşlandırma ve kriyojenik işlem ile alaşımın korozyon dayanımında çok büyük oranlarda iyileşme elde edilmiştir. Yaşlandırma ısıl işlemi ile en yüksek %51, kriyojenik işlem ile %92 seviyelerinde korozyon dayanımı artışı olmuştur. Yaşlandırma ile artan sertlik özelliği kriyojenik işlem ile daha da fazla artış göstermiştir. Kriyojenik işlem uygulaması ile alaşım sertliğinde 55 HV artış olmuştur. Sertliğin artması, alaşımının diğer mekanik özelliklerinin de geliştiğinin bir göstergesidir. Gerek korozyon dayanımı gerekse sertlik özelliklerindeki artışlarda, uygulanan ısıl işlemler sonucunda alaşımın mikroyapısında meydana gelen değişimler etkili olmuştur.
Unpacking Legal Accountability: The Case of the European Central Bank
Authors: Dawson Mark , Bobić Ana
Published: December 2024

Although the term “legal accountability” increasingly appears in scholarly discourse surrounding the European Central Bank (ECB), it is under-theorised. This article explores three different dimensions of legal accountability, which are often confused. Accountability to law refers to accountability to legal rules and standards. Accountability through law refers to achieving routes of administrative and political accountability through legal institutions. Accountability of law implies the accountability of legal institutions themselves to the wider public (and other courts) for their decisions. We argue that these dimensions are deeply connected in the sense that either improvements or failures along one dimension are easily carried to the others. We demonstrate the argument by applying our concept of legal accountability to ECB activity, comparing judicial review in the context of monetary policy with the Single Supervisory Mechanism. These cases suggest a possible vicious rather than virtuous circle of legal accountability, i.e., a tendency for either unclear legal standards or lack of accountability of courts themselves to undermine accountability for ECB activity as a whole.
Regular Octagons in Hyperbolic Geometry
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Prishlyak Oleksandr
Published: December 2024

When constructing hyperbolic structures on closed surfaces, one can use hyperbolic geometry (Lobachevsky geometry) on the plane. To do this, the surface must be represented as a 2n-gon on the hyperbolic plane, and a discrete group action, which is a subgroup of the movements of the hyperbolic plane, must be defined, for which the 2n-gon serves as a fundamental domain. If such a surface is a double torus (an oriented surface of genus 2), it can be obtained by gluing opposite sides of an octagon. In fact, the Lobachevsky plane is divided into octagons. The presence of symmetries simplifies calculations. Therefore, a natural problem arises regarding the partitioning into regular octagons. Additionally, it is important to provide examples of such octagons by specifying the coordinates of their vertices in one of the models of hyperbolic geometry.

The models of the upper half-plane and the Poincaré model on the unit disk are used, for which the Riemannian metric is defined (the formula for finding the lengths of arcs of curves). We describe the main properties of hyperbolic lines and the group of movements (the group of isometric transformations) of hyperbolic geometry on the plane using fractional-linear transformations of the complex plane with real coefficients.
