Description:

The developed and emerging countries strive for sustainability and focus on enhancing greener energy and electric products. Adopting electric vehicles and utilizing green energy sources are essential to this objective. This study examines the synergy between EV technologies, green energy, and sustainability in China using quarterly data from 2010Q1 to 2022Q4. In addition, it considers the policy-level roles of economic complexity and research and development efforts in the EV industry. The authors employ novel time-series methods to assess long-term associations, including unit root testing, the Bayer-Hanck cointegration test, FMOLS, and DOLS. Robustness is checked using both a parametric method (least squares with breaks) and a non-parametric method (quantile regression). The empirical results reveal that electric vehicle technologies, economic complexity, and R&D expenditures exert an unfavorable effect on greenhouse gas emissions. By contrast, green energy and economic globalization significantly reduce ecological emissions in the long run. The robustness check analysis through parametric and non-parametric provides robust and valid outcomes. Promoting the adoption of electric vehicles and investing in green energy, and research & development intiaitves have significant policy implications for attaining environmental sustainability. lastly, enhancing economic complexity and fostering economic globalization should be considered to ensure a stable environment and facilitate sustainable development and better environmental quality.

Innovating for Net-Zero: Collaborative and Digital Decarbonisation Strategies in Sunset Industries' Global Value Chains

Muhammad Mustafa Kamal Narain Gupta Attique ur Rehman Justin Zuopeng Zhang Ashem Emmanuel Egila Remsei Sándor Jianwen Zheng

Description:

Global net-zero ambitions require transformative strategies to decarbonise carbon-intensive global value chains (GVCs). This study examines how multinational enterprises (MNEs) in sunset industries integrate carbon capture technologies (CCT) with operational and supply chain dynamics (OSCD) to advance decarbonisation. Drawing on institutional theory (InsT) and dynamic capabilities theory (DCT), we investigate how external decarbonisation pressures activate internal capability routines that shape the adoption of technological and supply chain innovations. Using qualitative insights from 55 industry professionals across energy-intensive sectors, we analyse how firms navigate regulatory fragmentation, mobilise early-stage decarbonisation investments and develop collaborative and digital mechanisms to support low-carbon transitions. The findings reveal that coercive and normative pressures primarily stimulate sensing and seizing capabilities, while transforming capabilities develop more gradually through experiential learning and organisational reconfiguration. Firms often pursue hybrid CCT–OSCD strategies, combining technological interventions with operational and supply chain adjustments to manage institutional complexity. This study contributes theoretically by offering an integrated InsT–DCT framework that explains how institutional constraints and dynamic capabilities interact to enable decarbonisation in sunset industries. Managerially, the findings identify priority capability areas, including policy sensing, digital resource mobilisation and supply chain reconfiguration that can accelerate decarbonisation across global value chains.

Page Range: 1-21

Description:

Purpose – In the contemporary higher education landscape, there is an increasing emphasis on the integration of entrepreneurship education (EE) as a strategic tool to address societal challenges. However, there is a paucity of research that explores the manner in which EE contributes to sustainable innovation and community development in Central and Eastern Europe (CEE). Design/methodology/approach – A multiple-case study was conducted of three representative programmes from Hungary and Poland. Institutional and policy documents, programme materials, evaluations and official statistics were triangulated and then synthesized cross-culturally against predefined criteria. Findings – The following models have been identified as exemplars of best practice in this field: (1) Centrally coordinated, curriculum-embedded models [for example, Hungary’s Hungarian Startup University Program (HSUP)] that broaden access via credits, stipends and national coverage and (2) decentralized, ecosystem-anchored pathways (for example, Poland’s Aula Polska, PFR School of Pioneers and WUT’s Startup Entrepreneurship) that deepens community embeddedness through peer learning, mentoring networks and problem-driven projects. Across cases, entrepreneurship education fosters human-capital formation, opportunity recognition in green and social domains and university–community linkages; persistent challenges include high dropout rates, fragmented governance and weak long-term impact tracking. Originality/value – The present study demonstrates how governance design conditions EE’s sustainability contribution pathways, which are comprised of the following three elements: mindset formation, project-based experimentation and community and industry interfaces. HSUP primarily focuses on scaling inclusive access and early prototyping at the national level, while the Polish programmes primarily seek to strengthen local innovation communities and promote translational learning. The study contributes to the refinement of theory on entrepreneurial universities by establishing a correlation between EE design choices and sustainable innovation and community development mechanisms in CEE. Furthermore, it offers actionable implications for programme evaluation and funding.

Demographic Predictors Associated With Elevated Screen Use in Preschoolers: A Multinational Cross-Sectional Study Based on Parents' Reports

Publication Name: Child and Family Social Work

Publication Date: 2026-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

The widespread use of smartphones and tablets has greatly increased screen exposure among preschoolers. Since early childhood is crucial for cognitive, behavioural and social development, excessive screen time represents a major public health concern. Identifying factors influencing young children's screen use is vital for creating effective family guidance and health policies. Using convenience sampling, this study collected data from 633 parents across 31 countries to examine how family composition, parental and child characteristics affect the screen time of preschoolers (aged 1–5 years). The model, based on Ordinary Least Squares regression, explained 42% of the variance in children's screen time. Parental device-giving frequency emerged as the strongest predictor, with more frequent giving linked to greater exposure. Screen time also increased with child age and the number of children in the family. Children supervised by mothers had significantly less screen time than those supervised by fathers. Parental age, number of adults in the home, child's sex and temperament were not significant predictors. These findings highlight the significant impact of parental behaviour and household dynamics on preschoolers' screen habits. Interventions should directly target these factors, and family screen time guidelines must evolve to reflect the modern technology landscape, promoting balanced and healthy use.

Investigation of the Geometrical Deterioration Process of Tramway Superstructure Systems – A Case Study

Szabolcs Fischer Zoltán Major Mykola Sysyn Attila Németh Dmytro Kurhan Vivien Jóvér

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2026-01-01

Volume: 23

Issue: 1

Page Range: 345-364

Description:

Tramway tracks deteriorate over time due to operational loads, environmental conditions, and structural factors. This study analyzes the geometric degradation of Budapest's tramway tracks using long-term measurements. Track gauge and longitudinal level were assessed with the TrackScan 4.01 instrument to evaluate deterioration across different superstructure types. Findings indicate that concrete slab tracks experience gauge widening, while embedded rail systems tend to narrow under similar conditions, with structural design playing a greater role than traffic intensity. Measurement limitations highlight the need for improved monitoring tools. These insights support more effective maintenance strategies, ensuring greater durability and sustainability.

Structural behavior of built-up I-shaped high-strength cold-formed steel columns with edge-stiffened holes, unstiffened holes, plain webs, and batten reinforcement

Publication Name: Thin Walled Structures

Publication Date: 2026-01-01

Volume: 218

Issue: Unknown

Page Range: Unknown

Description:

Cold-formed steel (CFS) back-to-back channel sections are widely employed as load-bearing structural components due to their high strength-to-weight ratio and ease of fabrication. These sections are often perforated to facilitate service installations; however, the presence of holes alters stress distribution, reduces axial load capacity, and increases the complexity of structural analysis. To investigate these effects, a geometrically and materially nonlinear finite element (FE) model was developed and validated against experimental data from existing literature. Specifically, the validation results demonstrated a strong correlation, with the ratios of Finite Element Analysis (FEA) and Direct Strength Method (DSM) predictions to experimental findings being 1.001 and 1.003, respectively. These results indicate a high level of agreement between experimental data, FE analysis, and strength predictions according to the American Iron and Steel Institute (AISI) and the Australian/New Zealand Standards (AS/NZS). Subsequently, the validated FE model was utilized to perform an extensive parametric study involving 130 simulations to examine the influence of hole geometry, edge stiffeners, and batten reinforcement plates on the axial capacity of built-up CFS columns. The results indicate that unstiffened slotted holes lead to an approximate 10.3% reduction in strength, whereas edge-stiffened square holes contribute to a 2.7% increase in axial capacity. Additionally, batten-reinforced unstiffened rectangular holes and edge-stiffened rectangular holes were found to enhance strength by approximately 7.5% and 15.5%, respectively. Moreover, incorporating batten plate reinforcements in plain columns improved axial capacity by approximately 6%. These findings provide valuable insights into the structural behavior of perforated CFS built-up columns and highlight the effectiveness of hole stiffeners and batten reinforcements in mitigating strength reductions caused by perforations.

OPTIMIZING PATIENT TRANSPORT UNDER INFECTION CONTROL CONSTRAINTS: A MILP-BASED DIAL-A-RIDE APPROACH

Tamás Hajba Adrian Horváth Martin Tóth

Publication Name: Communications Scientific Letters of the University of Zilina

Publication Date: 2026-01-01

Volume: 28

Issue: 1

Page Range: E13-E20

Description:

With aging populations and rising healthcare demands, efficient patient transportation has become a critical challenge, particularly in the context of infection control. In this paper an extended mixed-integer linear programming (MILP) model for optimizing patient transport in urban environments is presented, with a focus on the separate transportation of infectious and non-infectious individuals. The model incorporates time windows, maximum allowable ride durations, and mandatory vehicle disinfection requirements. Experimental results obtained using CPLEX demonstrate that incorporating infection control measures significantly influences both route planning and computational complexity. The proposed approach provides a scalable foundation for future multi-vehicle extensions and cost-based optimization strategies.

Langevin neutral impulsive fractional stochastic system along fractional Brownian motion-A controllability analysis

D. U. Ozsahin Hijaz Ahmad Taha Radwan M. Lavanya B. Sundara Vadivoo D. U. Ozsahin

Publication Name: Journal of Low Frequency Noise Vibration and Active Control

Publication Date: 2026-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

The purpose of this work is to investigate the controllability of Langevin-type stochastic neutral impulsive integro-differential equations governed by the Caputo fractional derivative and driven by fractional Brownian motion, which arise naturally in systems exhibiting memory, impulsive effects, and stochastic disturbances. Using resolvent operators and fixed-point techniques, necessary and sufficient controllability conditions are established for the associated linear system, while the controllability of the nonlinear system is demonstrated via the Banach contraction principle. The theoretical results confirm that appropriate control functions can steer the system to a desired state within a finite time interval. Finally, illustrative numerical examples are provided to demonstrate the applicability and effectiveness of the obtained results, highlighting their relevance to practical stochastic control problems.
