Nedeczky Sándor, II. Rákóczi Ferenc diplomatája az orosz tábori kancellárián: 1707-1709 = Sándor Nedeczky, Francis II Rakóczi's Diplomat at the Russian field chancellery: 1707-1709
Get PDFThe military conflicts which have shaped the opening decades of the eighteenth century, such as the War of the Spanish Succession (1701–1713/1714), the Great Northern War (1700–1721), and the Russo-Turkish War, also exerted a decisive influence on the foreign policy of the Rákóczi’s War of Independence (1703–1711). An important episode in this context was the establishment of Russo-Hungarian contacts in 1707, and the treaty concluded between Tsar Peter I. and Prince Francis II Rákóczi in Warsaw. Under these terms, Rákóczi’s first permanent representative at the court of Peter I. was Sándor Nedeczky (1654–1719). Born into an old lesser noble family, Nedeczky pursued legal studies and had previously served within the royal administration of Hungary. By the autumn of 1706, he had already become a devotee of Rákóczi. Speaking several languages, Nedeczky was dispatched to Russia in the autumn of 1707, where he carried out his diplomatic duties faithfully until the end of the War of Independence in 1711. He met and negotiated with the highest-ranking figures of the tsarist government (including the tsar himself and the chancellor), as well as with foreign diplomats and military officers. During his stay in Russia, Nedeczky also witnessed the everyday realities of the Great Northern War. The present study publishes substantial, previously unpublished diplomatic, political, and military details drawn from the reports and letters he sent to Rákóczi, during the „pre-Poltava” period (1707–1709)
Kvalitatív munkaerőhiány és készséghiány az Észak-Alföld régióban = Qualitative labour and skills shortages in the Northern Great Plain region of Hungary
Get PDFCompetence theory has developed at the intersection of several academic disciplines and has become central to understanding labour market adaptability and employability. A clearly defined system of competencies not only shapes the content of education but also fundamentally influences the extent to which workers can meet the expectations of the labour market. Consequently, the absence of key competencies can lead to a specific form of labour shortage—qualitative labour shortage. This study aims to examine the extent to which this type of skill mismatch is present in the three counties of Hungary’s Northern Great Plain region, with particular attention to cases where jobseekers lack the skills and knowledge required for available positions. The empirical analysis is based on labour market data from the Hungarian Central Statistical Office (HCSO) for the period 2019–2024, with a focus on the ratio of job vacancies to registered jobseekers. To further illustrate and interpret labor market mismatches, the study also applies the Beveridge curve as a visual analytical tool, which helps identify structural and qualitative labour shortages at the regional level. The quantitative analysis is supported by a review of national and international literature, with special emphasis on the relationship between competence-based education and regional economic development. Based on the findings, the study offers recommendations for improving the alignment between educational supply and labor market demand

Get PDFOn a coupled nonlocal Schrödinger-Kirchhoff system with singular exponential nonlinearity in RN
Get PDFThis paper is concerned with the existence of solutions for parameters dependent Schrödinger–Kirchhoff system driven by nonlocal integro-differential operators with singular Trudinger–Moser nonlinearity in the whole Euclidean space RN. These parameters have a major impact on the produced analysis. It is noted that, we also study the asymptotic behaviour of solutions depending upon these parameters. The proofs of the existence results to the aforementioned system rely on the mountain pass theorem, the Ekeland variational principle, the classical deformation lemma, and the Krasnoselskii genus theory. The salient feature and novelty of this paper is that it also covers the so-called degenerate case of the Kirchhoff function, that is, it could vanish at zero
Second order neutral delay differential equations and their oscillatory criteria derived by linearization
Get PDFIn this paper, we investigate the oscillatory behavior of second-order neutral delay differential equations with a canonical operator of the form a(x) v (x) �m + C(x, u(φ(x))) = 0. We introduce new monotonicity properties of the non-oscillatory solutions of these equations, which are then used to linearize the equations and derive new oscillatory criteria. The presented results significantly improve upon existing criteria
On uniform asymptotic h-stability for linear nonautonomous systems
Get PDFA classical result in the theory of stability of nonautonomous linear systems is that the uniform exponential decay of its corresponding transition matrix is equivalent to the uniform asymptotic stability of the trivial solution. The aim of this article is to extend this equivalence for non-exponential decays h(t). In this article we prove that, in some suitable cases, the function h(t) allows the construction of a topological abelian group that makes possible to formulate a more general definition of uniform stability which is equivalent with a decay dominated by h(t). Moreover, we can use this group to establish the necessary elements to develop a theory of h-stable systems. As a first step in this direction, we provide integral conditions on the solutions of a uniformly asymptotically h-stable system
