Football and Politics in Twentieth-Century Hungary

Róbert Győri Szabó

Publication Name: International Journal of the History of Sport

Publication Date: 2019-02-11

Volume: 36

Issue: 2-3

Page Range: 131-148

Description:

In the eastern part of Europe football has always been in close relationship with the political sphere. As the most popular sport it was always a state affair in this area. In the countries surrounded by enemies and rivals suffering from inferiority complex, politics sometimes tried to use soccer as a means of legitimacy and propaganda. The nationalist political elites tried to exploit the political potentials of football. During the dualistic era (1867–1918) soccer was represented in Hungary as the symbol of cultural superiority especially in contrast to Austria; in the inter-war period it was an expression of symbolizing being European, the wish to belong to Western Europe and an evidence of Hungarians’ greatness in opposition to neighbouring countries. In the hands of totalitarian socialist powers, soccer became an even more important political vehicle in order to prove the superiority of socialism above capitalism, to legitimate dictatorship by exploitation football results as the regime’s own victories, and it could channel the sentiments and passions of the people. During ‘soft dictatorship’ of Kádár-era the political control over football remained unchanged, however influence was rather indirect and less drastic.

At the Borderline of Public and Private Law: The Restitution of Cultural Property Held in Public Collections in Hungary

Vanda Vadász Viktória Verebélyi

Publication Name: Santander Art and Culture Law Review

Publication Date: 2024-01-01

Volume: 2024

Issue: 2

Page Range: 181-208

Description:

During the Second World War, and thereafter until the end of the communist regime in 1989, a massive amount of private-ly owned works of art came into the possession of the Hungarian state. The ownership of the property thus collected was only par-tially clarified after the war. After the fall of communism, national-ized cultural property was subject to restitution laws, but restitution typically meant partial compensation. The aim of this article is to highlight the shortcomings that still characterize the restitution of cultural property held in public collections in Hungary. After summa-rizing the historical-legal situation pertaining to restitution measures in Central and Eastern Europe, we provide a comprehensive overview of the Hungarian legal environment in terms of restitution. The focus is on the restitution rules adopted in the 2010s that were intended to settle the possession of cultural property held in public collections. The roots of constitutional issues related to the regulation arise from and are reflected in the intermingling of private law and public law characteristics and guarantees. In the presentation of civil law disputes concerning the ownership rights of property held in public collections, we outline the characteristics of the Hungarian regula-tory framework regarding protected cultural property and the issues arising from their application. Finally, we provide an overview of the European Court of Human Rights’ jurisprudence on the protection of property rights and an assessment of Hungarian regulations before the Court. We claim that the lack of predictability and certainty of the latter authority’s proceedings may lead to human rights issues.

Investigation of the influencing soil parameters on the air entry values in soil-water characteristic curve of compacted heaving soils

Elizabeth Theron Armand Augustin Fondjo Richard P. Ray

Publication Name: Civil Engineering and Architecture

Publication Date: 2021-01-01

Volume: 9

Issue: 1

Page Range: 91-114

Description:

The air-entry value (AEV) is a fundamental parameter of the soil-water characteristic curve (SWCC). AEV is the minimum matric suction value required for entry of air into soil voids. The primary objective of this research work is to assess the impact of geotechnical index properties, swelling properties, mineral composition on AEV of compacted heaving soils, and discuss how they affect AEV. Soil properties were investigated through lab tests such as grain size distribution (GSD), specific gravity, Atterberg limits, linear shrinkage, free swell index, free swell ratio, X-ray diffraction, compaction test, and soil suction measurement. SWRC Fit program was used to perform non-linear fitting of the SWCC based on models VG, DB, FX, LN, and BL. Surface plot of data was used to characterize the impact of soil properties on AEV. It was observed that AEV is ranging from 10 kPa to 20.20 kPa, models DB and BL gives the best fitting SWCC. The percent of smectite mineral exhibits a significant impact on AEV. Swelling properties such as free swell index and free swell ratio influence the AEV with a respective determination coefficient of 85.72%, 88.68%. The plasticity index, linear shrinkage, specific gravity, and dry unit weight impact the AEV with a respective determination coefficient of 95%, 95.45%, 90.43%, 94.29%. The fine-grained content, clay fraction, void ratio, and water content influence the AEV with a respective determination coefficient of 97.95%, 84.89%, 80%, 94.31%. The finer the soil, the higher the AEV. The activity of clay and percent of illite mineral exhibit a marginal effect on the AEV.

A Hybrid LOPCOW–PROMETHEE framework under linear Diophantine fuzzy sets for sustainable planning

Dragan Pamucar S. Rajareega Jeevitha Kannan Vimala Jayakumar

Publication Name: International Journal of Optimization and Control Theories and Applications

Publication Date: 2026-01-13

Volume: 16

Issue: 1

Page Range: 321-348

Description:

Imprecision, uncertainty, and conflicting criteria often complicate the process of identifying the optimal conclusions in real-world decision-making scenarios. This paper suggests a novel multi-criteria decision-making (MCDM) framework that combines a hybrid logarithmic precursor chain-driven objective weighting–preference ranking organization method for enrichment of evaluations technique with linear Diophantine fuzzy sets to address uncertain frameworks. The selection of the location of a Sustainable Emergency Service Station and the selection of an investment portfolio are two real-world and socially significant decision-making challenges where traditional MCDM approaches fail to address the uncertainties. Our suggested fuzzy-based paradigm demonstrates the adaptability of both infrastructure design and financial decision-making. The results provide the optimal solutions based on our requirements, even under unpredictable conditions. The outcomes of sensitivity analysis and comparative analysis demonstrate how well the suggested approach handles ambiguous and imprecise data, particularly when expert opinions are presented in a linguistically or incompletely articulated manner. This work provides a solid, scalable, and precise method for resolving MCDM issues in the face of ambiguity, offering improved support to decision-makers in a range of fields.

Business Incubation as a Catalyst: Examining the Impact of Entrepreneurial Education on Entrepreneurial Intention in Emerging Contexts

Hirwan Jasbir Bin Jaafar Mohammad Fakhrul Islam Md Asaduzzaman Muhammad Asyraf Bin Mohd Kassim

Publication Name: Ianna Journal of Interdisciplinary Studies

Publication Date: 2026-01-05

Volume: 8

Issue: 1

Page Range: 202-217

Description:

Background: Entrepreneurial education (EE) and institutional support mechanisms such as Business Incubation Programmes (BIPs) play critical roles in shaping entrepreneurial intentions among university students. However, in Bangladesh, the relationship between EE, BIPs, and Entrepreneurial Intention (EI) remains underexplored, particularly from the perspective of resource-based and behavioural theories. Objective: Grounded in the Theory of Planned Behaviour (TPB) and drawing on the Resource-Based View (RBV), this study examines the role of BIPs in amplifying the impact of EE on EI among business students in Bangladeshi universities. Methodology: The study employed a quantitative research design, utilising a structured questionnaire administered to 388 business students from four leading universities in Dhaka. Data were analysed using SmartPLS 4.1.0.9 and SPSS 27 to test the proposed model and hypotheses. Results: The findings reveal that EE and BIP have a positive and significant influence on EI. Moreover, BIP substantially moderates the relationship between EE and EI, indicating that incubation programmes strengthen the effect of educational inputs on students’ entrepreneurial intentions. Conclusion: Integrating entrepreneurial education with institutional support mechanisms such as incubation programmes fosters a stronger entrepreneurial mindset and intention among students. Unique contribution: This study enriches entrepreneurship literature by integrating TPB and RBV perspectives to explain how cognitive and resource-based factors jointly shape entrepreneurial intention in an emerging South Asian economy. It also provides practical implications for educators, policymakers, and ecosystem stakeholders seeking to address graduate unemployment through entrepreneurship development. Key Recommendation: Universities should integrate business incubation Programmes with entrepreneurship education to provide practical support and enhance students’ entrepreneurial readiness.

Personal Watercraft Remote Control Communication Fault Detection †

Ádám Titrik

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

Hydroflight is a watersport where the user utilizes a waterjet-propelled backpack to fly over water. These backpacks are usually powered by purpose-built equipment but can also be propelled by personal watercraft. To have full control over movement during hydroflight, the user needs to adjust the throttle of the watercraft, which is commonly performed by converting the system to remote-controlled operation. However, care should be taken during conversion to ensure safe operation and avoid harm to the user. This paper presents a failure analysis of sudden safety mode activation on a personal watercraft converted to remote control for hydroflight applications, as well as actions taken to avoid full shutdown in the case of communication loss, without compromising user safety.
