This article proposes a methodology for assessing the effectiveness of regional strategies based on a transaction efficiency index that takes into account project benefits, transaction costs, and the quality of institutional support. The theoretical basis is the concept of a transaction configurator as an element of project management. Testing on a simulated strategy confirmed the applicability of the method. The results demonstrated the importance of reducing transaction costs, adapting the institutional environment, and digitalizing management to improve strategy effectiveness.

This article examines the concept of an offset contract and its interpretations in international and Russian practice. It analyzes the instrument's compliance with the key features of public-private partnerships and concludes that offset contracts should be considered a form of quasi-public-private partnership. Furthermore, the article analyzes the key advantages that offset contracts can provide for supporting regional investment development. It also provides a breakdown of concluded offset contracts by industry and region, confirming the low demand for this mechanism among the constituent entities of the Russian Federation, with the exception of Moscow. The author also examines the factors hindering the active conclusion of offset contracts by regions. The main reason is general macroeconomic uncertainty, which manifests itself through increased long-term investment risks. The rationale for providing additional government support measures for new investment projects implemented using offset contracts is justified, which will increase the attractiveness of this instrument for private investors.

This article presents an assessment of the security of the Russian Federation's sovereignty over its polar territories in the context of deglobalization and the division of the world into new associations of countries - macroregions. The analysis of the conditions of the state's strategic control over the Arctic and its connectivity with other regions of the country allows us to conclude that Russian sovereignty in this area is ensured in the medium term, and its strengthening depends on resolving the demographic problems of the eastern Arctic.

This article analyzes the transformation of international interactions in foreign trade and technology exchange under globalization. It explores the mechanisms by which countries transition from global integration to partial technological independence, driven by political and economic challenges. Particular attention is paid to the concepts of protectionism and industrial policy as tools for achieving competitiveness and innovative development. The article analyzes cases of leading economies demonstrating a balance between technological interdependence and the desire for autonomy in strategic sectors. It concludes that a selective approach to regulating international economic relations and technological cooperation is necessary.

This article presents the results of a regional assessment of food security in rural areas based on the proposed indicator system. The author identifies the following components of food security in rural areas: economic accessibility of food for socially vulnerable groups, spatial and infrastructural accessibility of food, rural self-sufficiency in agricultural products, and the quality of rural nutrition. By aggregating these indicators, an integrated index was obtained, as well as specific indices of food security in rural areas. The analysis of the integrated assessment framework revealed that current statistical monitoring is insufficient to assess the quality of the population's nutrition. There is a need for methodologically sound monitoring, taking into account the urbanrural divide. The cartogram-based assessment enables to draw conclusions about the spatial determinacy of food security inequality in rural areas. The integrated assessment methodology can be applied to spatially dynamic monitoring of food security in rural areas in the constituent entities of the Russian Federation, as well as to analyze spatial inequality in food security.

In the context of increasing commercialization of healthcare, studying the factors determining the volume of paid medical services is particularly important for resource management and the development of regional strategies. This article, based on data from 36 medical organizations in the Republic of Mari El, presents the results of a comprehensive analysis of the key determinants of revenue from paid services using factor and cluster analysis. Seven latent factors were identified, explaining 77.57% of the data variance, with the most influential factors being technical equipment (F1), facility scale (F2), and revenue dependence on paid services (F3). Clustering enables to identify five types of organizations with distinct business models: mass market, specialists, budgetary institutions, multidisciplinary centers, and premium class. The study's results can be used to optimize the management of paid services in healthcare, as well as to develop investment decisions and marketing strategies for medical organizations.

This article analyzes the persistent shortage of qualified personnel in Russia's regions. The author highlights a paradox: despite significant investments and the creation of numerous innovative facilities, the personnel shortage in the regions remains stagnant. Using a SWOT analysis, it examined the strengths and weaknesses of innovative educational structures, as well as the opportunities and threats associated with their development. The article analyzed key issues (lack of coordination between infrastructure facilities, inconsistency in development programs, and youth outflow from the regions). Based on this analysis, the author makes recommendations for overcoming systemic failures and improving the effectiveness of regional personnel policies.

This research aims to develop and analyze a hybrid digital signature protocol, QDS-Hybrid, which combines quantum verification and the post-quantum Dilithium algorithm. The objectives of the research include ensuring resistance to quantum attacks and classical threats, optimizing the speed of signature generation and verification while maintaining unconditional security based on quantum mechanics, and identifying solutions to the problems of quantum memory, decoherence, and scalability of existing QDS protocols. The research proposes a hybrid approach based on quantum-classical synthesis. The paper also provides a proof of security using the qCMA (Quantum Chosen Message Attack) model and universal compositional security (UC). The protocol provides protection against state substitution and man-in-the-middle (MITM) attacks through QZKP (Quantum Zero-Knowledge Proof). It is proven that a hack requires simultaneously breaking Dilithium and QKD. The paper proposes solutions for eliminating dependence on quantum memory through dynamic state generation and one-time keys. The paper demonstrates paths to decentralization through blockchain and quantum Byzantine agreements. The key innovation obtained in the study is a hybrid architecture that integrates Dilithium with quantum verification via phase encoding. Implemented QZKP verification helps for signature authenticity confirmation without revealing the secret key, using the properties of quantum entanglement and the no-cloning theorem. QDS-Hybrid demonstrates a practical compromise between security and efficiency, addressing the key shortcomings of purely quantum protocols.

This article examines the development of theoretical foundations for intertemporal modeling of career choice based on the integration of human capital development and an individual's psychological profile. The authors propose a model for formalizing career choice by solving the problem of optimal career management under uncertainty. The results demonstrate that the inclusion of psychometric congruence and a multidimensional skill structure enables a quantitative assessment of the stability of career trajectories. This study advances the methodology of dynamic models of career choice. These models are capable of taking into account the multidimensional structure of skills and psychological congruence, thereby complementing existing approaches in career guidance modeling.
