Eternal Stewardship in Law: The Legal Concept and Temporal Aspects of Sustainable Development

Gergely Horváth

Publication Name: Journal of Agricultural and Environmental Law

Publication Date: 2025-12-10

Volume: 20

Issue: 39

Page Range: 423-441

Description:

Although sustainable development is a late twentieth-century construct, its foundations can be traced to classical legal cultures, particularly Roman and Jewish law, which embedded resource stewardship, communal access, and intergenerational equity. Contemporary legal discourse presents numerous definitions; this study therefore conducts a selective comparative analysis, emphasizing the Hungarian legislative definition and its environmental focus. The research demonstrates that a precise and unambiguous definition of sustainable development is essential, as the pathway toward sustainability remains unclear without it. It is not enough to ensure “the long-term” improvement of quality of life and preservation of biodiversity, it is crucial to prevent the collapse of ecological systems. In the context of sustainability, the temporal dimension emerges as paramount, necessitating a perspective “sub specie aeternitatis” – that is, an orientation toward the perpetual existence of humankind, framed within the horizon of eternity. Although the tendencies appear unfavorable, or even hopeless, there remains potential for a positive outcome.

Parasomnias manifest different phenotypes of sleep-related behaviors in age and sex groups. A YouTube-based video research highlighting the age slope of sleepwalking

Vivian M. Correa József Vitrai Anna Szűcs

Publication Name: Journal of Clinical Neuroscience

Publication Date: 2024-04-01

Volume: 122

Issue: Unknown

Page Range: 110-114

Description:

Study objective: Finding typical patterns - phenotypes - of sleep behaviors characterizing parasomnias in different age and sex groups. Methods: We analyzed YouTube videos on sleep-related behaviors likely representing parasomnias. We applied the search terms “sleepwalking”, “somnambulism”, “sleep eating”, “sleep sex”, “sleep talking”, and “aggression in sleep” in six languages. We classified those persons shown on the videos into estimated biological sex and age (child, adult, elderly) groups. We scored the activity types by a self-made scale and applied binary logistic regression to analyze the association between sleep behaviors versus sex and age groups by the STATA package, providing a 95% confidence interval and the probability of statistical significance. Results: 224 videos (102 women, 68 children, 16 adults, and 40 elderly people) were scored. Elderly people had significantly (P < 0.012) lower odds of sleepwalking compared to adults and children. Adult females performed complex manual activities during sleepwalking more often than males (P < 0.012). Elderly males had 40-fold odds compared to adults and children, to perform aggressive movements and 70-fold odds of complex movements in bed, compared to adults. Elderly people presented emotional behaviors less frequently than adults (P < 0.004), and females showed them twice as often as males. Adults sleep-talked full sentences more often than children and elderly people (P < 0.001). Conclusion: Our results support the existence of age- and sex-specific parasomnia phenotypes, denoting possible safety measures. The remarkably low odds of sleepwalking in the elderly highlight the possibility of different pathomechanisms in higher age groups compared to children. Brief Summary and study impact: Parasomnias present highly variable clinical forms and often cause injuries. Identifying typical phenotypes may help risk management and imply theoretical conclusions. Our study supports the existence of age-specific parasomnia phenotypes. We found that adult women have a high risk of performing dangerous activities during sleep, and elderly males often move violently in bed, likely representing dream enactment behaviors. Elderly people of both sexes have low odds of sleep ambulation- likely representing somnambulism; compared to adults and children, constituting a descending “age slope” of somnambulism that might reflect different underlying pathomechanisms in children versus adults and the elderly.

Influencing Factors of International Trade in Food Resources: Land, Economic, and Social Features

Laszlo Vasa Lubos Smutka Kunlin Zhu Fenghua Liu Jiangtao Gao Xiangli Guo

Publication Name: Land Degradation and Development

Publication Date: 2026-04-15

Volume: 37

Issue: 6

Page Range: 2149-2165

Description:

International food resource trade serves as a critical mechanism for ensuring global food security and promoting worldwide economic development, which involves multidimensional interactions spanning land, economic, and social factors. Utilizing panel data from 40 countries (2003–2023), this study establishes an evaluation index system for international food resource trade based on agricultural endowments, economic development, and geographic characteristics. QAP analysis was employed to systematically investigate the primary influencing factors of international food resource trade. Results indicate that per capita arable land area, national GDP, trade structure, and legal safeguards exert sustained and significantly positive effects on international food resource trade. Geographical distance between countries and population size demonstrates statistically insignificant impacts. Policy regimes—particularly disparities and uncertainties in tariff rates—impede international food resource trade. In conclusion, countries should strengthen cooperation to refine trade policies and legal frameworks through strategic alignment of food resource trade. Proactively establishing international food trade platforms will enhance the efficient allocation of global food resources and facilitate collective responses to global food security challenges.

Determining factors for tourist arrivals in Hungary

Ferenc Bakó Marcell Kupi

Publication Name: Journal of Infrastructure Policy and Development

Publication Date: 2024-01-01

Volume: 8

Issue: 8

Page Range: Unknown

Description:

This methodologically focused study examines the relationships between inflation and unemployment rates, political stability, and tourism, with particular emphasis on the impacts on tourist arrivals in Hungary. The research aims to uncover the direct and indirect influences of these macroeconomic indicators on the volume of tourism, specifically international tourist arrivals. The significance of the study lies in the clear correlation between economic stability and labor market conditions with tourism volume, where rising inflation and unemployment rates negatively correlate with the number of tourist arrivals. This relationship is further strengthened by the observation that improvements in political stability enhance tourist numbers over the long term, while political instability, such as conflicts and terrorist acts, negatively affects tourism demand. These correlations are crucial for aligning tourism policy with economic policy, as macroeconomic indicators and the political environment directly influence both domestic and foreign tourists’ willingness to travel. The research methodology focuses on forecasting using Random Forest and neural networks, which enables more accurate predictions of tourism volume and supports informed tourism policy-making. The findings indicate that the development of the tourism sector is closely linked to economic growth and underscore the necessity of boosting tourism to expand employment and maintain economic stability.

Ctrl + Alt + Remedy? Child Rights, Access to Justice and Preventive Responses to Cyberbullying in the European Union

Enikő Kovács-Szépvölgyi Bernadett Szakács Brigitta Molnár

Publication Name: Societies

Publication Date: 2026-04-01

Volume: 16

Issue: 4

Page Range: Unknown

Description:

This study examines how European Union Member States address cyberbullying affecting children through legal and policy frameworks, paying particular attention to children’s rights. It employs a qualitative, document-based comparative methodology, applying a harmonized codebook to analyze definitional, legal, preventive, and reactive responses across all 27 EU Member States. The analytical framework is grounded in the EU Charter of Fundamental Rights, the EU Strategy on the Rights of the Child, the Better Internet for Kids (BIK+) initiative, and the Digital Services Act, which serve as normative benchmarks. Coding draws on EU-level harmonized sources, including Joint Research Centre outputs and the 2025 BIK policy reports, and aggregates the findings into a composite structural indicator capturing the formal regulatory and policy coverage of cyberbullying from a child rights perspective. The results indicate a high level of formal regulatory attention in most Member States, particularly regarding criminal law protection, educational prevention, and institutional reporting mechanisms. However, child-specific and child-friendly elements—such as explicit cyberbullying definitions, adapted reporting procedures, and tailored civil law remedies—remain uneven and limited. The study concludes that, despite comprehensive formal regulation, significant gaps persist in the integration of child-centered and access-to-justice-oriented mechanisms, underscoring the need for strengthened child rights approaches and further research on implementation and children’s lived experiences.

Convergence of the key algorithm of traffic-flow analysis

László Muka Gábor Lencse

Publication Name: Journal of Computing and Information Technology

Publication Date: 2006-01-01

Volume: 14

Issue: 2

Page Range: 133-139

Description:

The traffic-flow analysis (TFA) [1] is a novel method for the performance estimation of communication systems. TFA is a combination of simulation and numerical methods. In the first step, TFA distributes the traffic in units of properly chosen size using the actual routing algorithm of the network. In the second step, TFA adjusts the time distribution of the traffic according to the finite capacities of the network. The convergence of the algorithm used in the second step of TFA is proven in this paper. The speed of convergence is also examined.

Jenő Kontschán Edith Guadalupe Estrada-Venegas Stacy R. Blomquist Alejandro Rodríguez-Ortega John C. Moser Martha Patricia Chaires-Grijalva Armando Equihua-Martínez Víctor Javier Arriola-Padilla Mauricio Pérez-Silva

Publication Name: Acarologia

Publication Date: 2026-01-01

Volume: 66

Issue: 2

Page Range: 364-376

Description:

Phoretic mites associated with bark beetles (Curculionidae: Scolytinae) play crucial roles in forest ecosystems, yet their diversity and distribution in Mexico remain understudied. This study aims to identify the species of the family Trematuridae (genera Trichouropoda and Oodinychus) associated with bark beetles across major coniferous forests in Mexico and to describe their host specificity and attachment patterns. A total of 1,713 bark beetles belonging to nine species were examined from 24 Mexican states. Mites were collected from the host bodies, galleries, and collection vial sediments. Eleven trematurid species were identified. Mites were recorded in ten states, with Trichouropoda polytricha being the most widespread and generalist species, associated with seven host species. A significant disparity in mite prevalence was observed among hosts, ranging from 1.57% in Dendroctonus mexicanus to 25.58% in D. rhizophagus. Phoretic deutonymphs exhibited a clear preference for specific attachment sites, primarily the ventral surface (29%) and gular area (22%). Furthermore, the presence of mites in both new and old galleries confirms these structures as essential micro-ecosystems for their biological cycle. Our findings highlight a high degree of host plasticity in certain species and a complex symbiotic relationship within the gallery environment. This research provides a fundamental baseline for future studies on the ecological impact of mite-beetle associations in Mexican forest health.

Wear behaviour of ceramic particle reinforced atmospheric plasma spray coatings on the cylinder running surface of internal combustion engines

Ibolya Zsoldos Alexander Dudás András Lajos Nagy Gabor Laki Barna Hanula Dirk Bartel

Publication Name: Wear

Publication Date: 2022-08-15

Volume: 502-503

Issue: Unknown

Page Range: Unknown

Description:

Atmospheric plasma spray coatings can provide a solution for corrosion and wear resistant cylinder coating surfaces in hybrid powertrains. This article presents experimental results from a model study of metal matrix composite coating samples of chromium steel with varied ceramic content, in order to characterize the effect of hard particles and porous coating structure on friction and wear. Experiments were conducted on a high-frequency reciprocating rig with coated cast-iron cylinder segments and hard chromium coated piston ring segments. Samples were investigated under continuous and scarce lubrication conditions. A ceramic content of 35 wt% was found to be ideal in terms of friction and wear. Coatings with a higher ceramic content exhibited severe abrasive wear, whereas a ceramic content under 35 wt% allowed for increased adhesion between the ring and cylinder surfaces. A detailed investigation of focused ion beam milled sections of the coated cylinder wall segments revealed a stabilizing effect of the ceramic particles, which reduces the delamination of the coating structure.
