An Approach to Estimating the Economic Expediency of Developing a New Cargo Transport Hub by a Regional Public Administration
International Journal of Public Administration. 2021. Vol. 44. No. 13. P. 1076–1089.
Regional authorities consider the expediency of developing a new cargo transportation hub in the region in which it would provide transshipment services. It is considered that each transportation operator working in the region will use these services only if they are competitive with the currently existing ones. This competitiveness for a particular cargo means that the total transportation tariff for moving this cargo does not exceed (substantially or in principle) the (minimal) currently existing one as a result of including a transshipment via the hub in the transportation scheme for the cargo. A verifiable sufficient condition for the transshipment service competitiveness is proposed. Its verification consists of establishing the solvability of a system of linear inequalities being part of the system of constraints in the problem of finding optimal competitive transshipment tariffs for a set of cargoes expected to be moved via the hub. The latter problem is formulated as a quadratic programming one.

Maintaining plant health is crucial for crop quality, food security, and agricultural productivity. Although deep learning methods have shown strong potential for species, disease, and severity classification, most existing approaches tackle these tasks separately, failing to exploit shared representations and interdependencies among them. Furthermore, the variability of disease symptoms, such as subtle differences in size, ...

Статья посвящена проблеме применения специальных финансово-экономических знаний при рассмотрении дел о картельных соглашениях. Автор исходит из того, что российская правоприменительная практика по делам о картелях исторически опирается преимущественно на поведенческие и цифровые «следы» сговора, тогда как экономический анализ зачастую играет вспомогательную роль. На основе анализа отечественного и зарубежного опыта обосновывается тезис о необходимости разграничения двух ...

This article examines the theoretical and practical dimensions of carbon taxation. It assesses the extent to which the existing tax mechanism regulates CO2 emissions and whether tax revenues cover the damage caused by those emissions. The advantages and disadvantages of emissions trading systems and carbon taxes are analyzed. The article reviews the scholarly debate involving ...

This study explores the relationship between subjective well-being (SWB) and entrepreneurial intention (EI) among university students in Russia, where entrepreneurial engagement remains relatively low. It emphasizes the role of internal psychological drivers, such as SWB, willingness to take risks and entrepreneurial self-efficacy, rather than focusing solely on external factors. Drawing on the Theory of Planned ...

In the circular restricted three-body problem, families of periodic and quasi-periodic orbits exist in the vicinity of the libration points and are of significant interest for practical applications. This work presents a neural network-based algorithm for orbit construction and station-keeping, applicable to both periodic and quasi-periodic orbits near collinear libration points. The method employs a ...

Increasing female representation in technical majors, traditionally associated with high earnings, is recognised as a mechanism for promoting gender equality in the labour market. However, if women quit STEM soon after graduation, increasing their proportion in relevant disciplines will not help reduce the gender wage gap. This paper provides new evidence of the ‘leaky pipeline’ ...

В данном исследовании рассматривается связь между интеллектуальным капиталом компаний и их интернационализацией в условиях внешних шоков. В отличие от предыдущих работ, как правило, рассматривающих взаимосвязь интеллектуального капитала и интернационализации в стабильной экономике, в исследовании развиваются предположения о неоднородном влиянии шоков на компоненты интеллектуального капитала и, соответственно, различном модерационном эффекте шоков на трансформацию интеллектуального капитала в экспортную ...

We provide an infinite series of commutative finite-dimensional Gorenstein local algebras A_n for n ≥ 2. We give an elementary proof that the maximal ideal of every algebra A_n possesses a one-dimensional subspace that is different from the socle and invariant under the automorphism group of A_n. The latter implies that the algebras A_n fail ...

An inverse problem of reconstructing the turbulent exchange tensor from large archives of observed wind profiles within the Åkerblom–Ekman (A-E) model framework is investigated using high-vertical-resolution radiosonde observations. The reconstructed tensor provides improved agreement between modeled and observed wind profiles compared to classical formulations based on real turbulent exchange coefficient. Instead of the classical A-E ...

We analyze the interaction of a quasi-periodic subsystem, in which two-, three-, and four- frequency quasi-periodic oscillations are possible, with a chaotic subsystem. A discrete version is obtained via the Euler scheme from the corresponding flow model. The dynamics of individual subsystems are discussed, including quasi-periodic bifurcations of invariant tori and the occur rence of ...

We develop a new three-party quantum secret-sharing (QSS) protocol based on a three-qubit W state. This protocol encodes the secret-sequence bits using X gates and employs randomly selected Hadamard operations and measurement bases to generate information and security-test rounds. We evaluate the efficiency of the proposed protocol and analyze its security against an internal adversary ...

The carbon balance of an ecosystem is the difference between Gross Primary Productivity (GPP) and Ecosystem Respiration (Reco) as expressed by Net Ecosystem Exchange (NEE). While remote sensing retrievals of GPP have reached maturity, Reco estimation remains underexplored and ultimately cast bias on NEE.

A noncommutative projective variety is defined, following Artin and Zhang, by a graded coherent algebra 𝐴. The category of coherent sheaves is then the quotient qgr(𝐴) of the category of finitely presented graded modules by the subcategory of torsion modules.

If a symmetric multilinear algebra is weakly nil, then it is Engel. This result may be regarded as an infinite-dimensional analogue of the well-known Jacobian theorem, which states that if a polynomial mapping has a polynomial inverse, then its Jacobian matrix is invertible. This refines a theorem of Gerstenhaber and partially answers a question posed ...
