Introduction of a New Variable and the Problem of Complexity in Determining Impact Speeds in Vehicle–Pedestrian Accidents

Diána Henézi Csaba J. Májer

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2025-08-15

Volume: 53

Issue: 4

Page Range: 381-388

Description:

Reconstruction and analysis of road traffic accidents represent an inherently complex task. This is especially true for one of the most significant accident categories, vehicle-pedestrian collisions. Forensic traffic and vehicle technical experts must determine the relevant impact speeds in virtually all cases, based on a wide variety of objective traces. The most relevant evidence and information can be obtained on-site within a limited period following the occurrence of the accident. These indispensable sources of information cannot be reproduced later or can only be reproduced to a very minimal extent. Therefore, it is essential to uncover as many traces at the accident site as possible and as soon as possible. In certain cases, the so-called rapid expert calculations may need to be performed on-site. In this paper, we seek solutions related to these rapid calculations and to facilitating the determination of speeds that play a critical role in vehicle-pedestrian accidents. The proposed approach may simplify the daily work of forensic traffic and vehicle technical experts.

Unanswered Questions on the Registration of Electric Scooters from the Perspective of the Automotive Industry and the Law

I. Lakatos Lea Pődör

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2025-08-15

Volume: 53

Issue: 4

Page Range: 364-370

Description:

The rise of micromobility has brought increased use of low-speed transport devices such as electric scooters, Segways, and e-bikes. Despite their global popularity, the legal status of electric scooters remains unclear. A key regulatory question is whether e-scooters should be classified as vehicles. While some European countries consider them vehicles, others place them under existing categories like mopeds or bicycles, or even classify them as pedestrian devices. This classification affects all subsequent regulatory considerations. This study focuses on the registration of electric scooters, a topic with limited information despite its potential to address legal issues like theft and liability. The analysis examines regulatory frameworks in select European countries, compares them with practices in certain U.S. states, and highlights successful approaches in Asia, notably Singapore. The findings emphasize the role of vehicle databases in legal problem-solving and evaluate the effectiveness of existing systems. It may also be an incentive for the legislator to consider whether appropriate solutions can be found for the registration of other means of transport (e.g., bicycles, mopeds) and whether the adoption of these options could be appropriate for electric scooters.

Publication Name: Ecologica Montenegrina

Publication Date: 2025-08-15

Volume: 89

Issue: Unknown

Page Range: 161-168

Description:

Landouria canalifera Páll-Gergely, Tumpeesuwan & Tumpeesuwan sp. nov. is described from Koh Samui, southern Thailand. It is characterized by a deep groove inside the umbilicus on the last ca. 1.5 whorls, corresponding with a columellar fold in the aperture. Also, there is a basal apertural tooth, corresponding with a shallow groove on the basal side of the shell just behind the peristome. These two barriers form a shallow canal in the aperture. Although the reproductive anatomy of this new species is not known, it probably belongs to the genus Landouria, which is widespread in Thailand and in the neighboring countries.

From Agricultural and Forest Land Development to Urban Landscapes: Green Energy's Influence on Global Pollutant Emissions

Laszlo Vasa Irum Shahzadi Urszula Mentel Muhammad Adnan Bashir Irum Shahzadi Li Qing

Publication Name: Land Degradation and Development

Publication Date: 2025-08-15

Volume: 36

Issue: 13

Page Range: 4672-4690

Description:

There is a sharp inclination to use green energy sources such as solar, hydro, and nuclear energy to accomplish the COP29 targets and sustainability goals. The current study attempts to explore the role of green solar, hydro, and agriculture land use apropos global pollutant emissions. In doing so, the study examines the impacts of agricultural land use, forest area, and urbanization on global emissions. The study uses the global historical data from 1990Q1 to 2021Q4. The authors employ the diagnostic tests, autoregressive distributed lag models, and causality analysis for empirical analysis. The autoregressive distributed lag model's results mentioned that agricultural land and forestry also help improve environmental sustainability and urban landscape in the short and long run. In addition, the results find linear and nonlinear impacts of green solar and nuclear energy to mitigate the global carbon emission levels. The structural change policies of industrialization and urbanization remain the critical obstacles to attaining environmental sustainability. The on-hand research contributes to the ongoing challenges faced by global economies regarding green energy sources, agriculture land management and their criticality in attaining a sustainable environment by reducing carbon emissions. The research recommends further investments in green solar, agriculture land management, and incentivizing clean energy sources to achieve sustainable global development.

Ethical leadership and organizational resilience: exploring the interconnected dynamics

Gábor Szábo-Szentgróti Nikolett Gyurián Nagy Mohammad Reza Onsori

Publication Name: International Journal of Ethics and Systems

Publication Date: 2025-08-15

Volume: 41

Issue: 3

Page Range: 727-760

Description:

Purpose The purpose of this paper is to provide insights into the mechanisms through which ethical leadership impacts organizational resilience and fill the gap in the existing literature that has largely studied the two variables in isolation. Design/methodology/approach This study uses a systematic literature review, using peer-reviewed articles focused on ethical leadership and organizational resilience published between 2018 and 2024. This study uses databases like Scopus, Google Scholar and Web of Science and keywords including “ethical leadership,” “organizational resilience” and their intersections. Findings The findings of this study are based on the review of 14 selected papers. The review found that ethical leadership significantly enhances organizational resilience by nurturing organizational culture (organizational learning culture, ethical culture, ethical reporting, system thinking and ethical climate), promoting organizational flexibility (ability to adapt and ability to innovate) and positively impacting human capital (employee ethical conduct, trust, readiness to change, citizenship behavior, creativity and commitment). Key findings indicate that ethical leaders influence the organizational culture, supporting resilience strategies. Research limitations/implications This study’s limitations include a limited literature search, restricted to certain databases and peer-reviewed articles in English. The focus on studies conducted between 2018 and 2024 and the methodological diversity of the studies further limited the ability to draw overall conclusions. Originality/value This study’s originality lies in the lack of studies explicitly linking ethical leadership and organizational resilience. Most studies implicitly suggest that ethical leadership promotes organizational resilience through isolated mediating factors. This study contributes to advancing theoretical mechanisms through which ethical leaders impact resilience and suggests practical applications in organizations that want to achieve sustainability in turbulent times.

Increasing Navigation Safety by Introducing the Modern DunaInfoControl Control System

T. Péter Sándor Götz János László Bóta

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2025-08-15

Volume: 53

Issue: 4

Page Range: 406-419

Description:

The study presents a development proposal coordinated by the Hungarian Academy of Engineering (MMA) for intelligent navigation management on the Danube. We analyse the introduction of a security-enhancing central control system based on the IDM model. The publication reviews the main issues related to navigation safety in Hungary. Without claiming to be exhaustive, in the field of water transport control theory and practical applications, important players include HUN-REN SZTAKI, Budapest University of Technology and Economics, Széchenyi István University, HungaroControl Zrt. and the Water Police. This development requires combining modern control theory and a high-capacity 5G network. The program proposes the implementation of intelligent control in the first phase in the Budapest area, between river km 1660 in the north and river km 1633 in the south. This is because accidents much larger than the "Hableány" boat tragedy that occurred in Budapest on the evening of May 29, 2019, at 9:05 p.m., may occur in this section in the future. Consider, for example, the appearance of convoys transporting 6000-8000 tons of dangerous goods on the Danube. These represent a very serious source of danger in the event of collisions with the Budapest bridge piers. The proposal also intends to support the RSOE river IT system (developed by NOVOFER Zrt.), which has been built and operating since the end of 2018.

Financial Geographic Accessibility and Corporate Innovation: An Analysis of Spatial Synergy Based on Land Use and Environmental Sustainability

Laszlo Vasa Xin Zhao Yuping Shang Dariusz Cichon Liwen Wan Long Zheng

Publication Name: Land Degradation and Development

Publication Date: 2025-08-15

Volume: 36

Issue: 13

Page Range: 4562-4587

Description:

In the face of land degradation and environmental constraints, it is imperative to have an adaptive financial geography structure and a land resource utilization system that supports corporate innovation. This study constructs a refined financial geographic accessibility measurement index. By integrating multi-source spatio-temporal big data, the study breaks through the static limitation of traditional statistical data. It accurately analyzes the spatial synergistic effect between the spatial distribution of financial institutions and land use planning. Land use data, such as spatial development rate and spatial interest points, provide high-precision spatial evidence for revealing the mechanism of financial geographic accessibility affecting corporate innovation. Further, from the environmental sustainability perspective, this paper studies the moderating effect of environmental constraints on corporate innovation. Financial geographic accessibility can improve corporate innovation by reducing financing costs, accelerating knowledge spillover, realizing intermediate input sharing, improving labor matching, and giving play to location advantages. Notably, this facilitation effect performs better in cities with high energy consumption and carbon emissions. Heterogeneity analysis shows that proximity to the city center, low industrial maturity, government subsidies, soes, and large-scale corporations significantly amplify the innovation benefits of financial geographic accessibility. This study combines remote sensing data with spatial big data to provide a new methodological framework for analyzing land use and degradation.

Description:

Waste management is a crucial and significant subject that has gained much attention globally because it has several environmental, social, financial and economic implications. Solid waste management is a very challenging task for clean urban and rural societies. We studied some reliable strategies for handling the waste materials and garbage produced by people. To serve this purpose, an intuitionistic fuzzy set (IFS) is a well-known model used for modeling and processing unpredictable information and providing accurate approximated results in the decision-making process. Power average operators allow the interrelationship of the input arguments and deal with uncertain information in complicated situations. This article expresses Sugeno-weber triangular norms under intuitionistic fuzzy (IF) information. We developed a class of new aggregation operators, including intuitionistic fuzzy Sugeno-Weber power-weighted average (IFSWPWA) and intuitionistic fuzzy Sugeno-Weber power-weighted geometric (IFSWPWG) operators. It is observed that both the newly proposed operators satisfy the properties of aggregation. The multi-criteria decision-making (MCDM) problem is proposed to evaluate real-life applications and numerical examples. An experimental case study under the system of waste materials is considered in the article to reveal the intensity and applicability of derived approaches. The comparison analysis and sensitivity analysis show the significance of our proposed work.
