The development and application of a global positioning system – based monitoring system for soil stabilization vehicles
Publication Name: Journal of Ecological Engineering
Publication Date: 2025-01-01
Volume: 26
Issue: 3
Page Range: 1-7
Description:
The accuracy and efficiency of soil stabilization works are key to ensuring the durability of roads. During the conducted research, a GPS-based (global positioning system) tracking system was developed that can monitor the movement of soil stabilization vehicles in real time, recording the exact location and working width of the stabilized road sections. The system’s software solutions enable the conversion of location coordinates from the WGS84 (World Geodetic System) system to EOV (EOV as Uniform National Projection system) format and visualization of the results in AutoCAD. The developed tool can significantly contribute to the improvement of the quality control of soil stabilization works, as the development of road defects resulting from stabilization errors can be reduced with the help of documentation and visualization. During the testing of this system, the development proved to be successful and provides an opportunity to perform soil stabilization processes more efficiently and reliably, thereby improving the service life of road surfaces and traffic safety.

Determination of Optimal Process Parameters for L-PBF Produced 1.2709 Alloy †
Publication Name: Engineering Proceedings
Publication Date: 2025-01-01
Volume: 113
Issue: 1
Page Range: Unknown
Description:
For L-PBF (Laser Powder Bed Fusion) metal additive manufacturing (AM) the choice of available materials is still limited. 1.2709 maraging steel powders are widely used for injection molds and high-quality engineering parts. The quality of the parts produced by L-PBF are significantly affected by the process parameters. The aim of this research was to find optimal process parameters for producing 1.2709 tool steel at a layer thickness of 20 µm and to reveal the possible parameter settings yielding comparable build quality as the “EOS surface” parameter set at a layer thickness of 20 µm. Findings showed that too low or too high input energies produce improper parts. A large range of parameters produce good quality parts, of which the optimum parameters can be chosen.

The other side of war or migration and labor market imbalances: Evidence from Eastern Europe for the period 2014–2025
Publication Name: Journal of International Studies
Publication Date: 2025-01-01
Volume: 18
Issue: 4
Page Range: 44-64
Description:
This study investigates whether war-induced forced migration has led to persistent imbalances in Eastern European labor markets, with a specific focus on matching efficiency. The analysis utilizes a quasi-experimental design combining Eurostat and UNHCR quarterly panel data for the EU-27 from 2014 to 2025. The methodology employs a multi-period difference-in-differences approach and Beveridge curve regressions to isolate the specific impact of the Temporary Protection Directive flows. The findings indicate an upward and outward shift in the Beveridge curve following the 2022 shock, characterized by a simultaneous increase in vacancies and unemployment. The results demonstrate that high institutional integration capacity dampens these shock effects, while persistence primarily observed in service-intensive sectors. The study suggests that reducing matching costs through targeted language equivalence accelerators and fair placement algorithms is essential for market stabilization.

HOUSEHOLD EXPENDITURES AS AN INDICATOR OF LIVING STANDARDS
Publication Name: Economics and Sociology
Publication Date: 2025-01-01
Volume: 18
Issue: 4
Page Range: 224-243
Description:
Expenditures are one of the fundamental indicators of living standards and quality of life. According to Maslow, human needs can be divided into basic and higher-order needs. The structure of expenditures and its changes allow for the identification of economic and social differences between social groups. The study covered the period 2004–2023. The main indicators are the level, structure and relations of expenditures. Households of basic socio-economic groups and by place of residence (rural and urban) were compared. The study showed convergence of the standard of living of rural and urban inhabitants and of farmers and other groups of households. Convergence was primarily the result of a higher dynamics of growth of expenditure of rural in-habitants than of urban inhabitants and of farmers compared to other groups of households. However, significant differences in the expenditure structure remained, with agricultural households characterized by a higher share of basic expenditures, such as food.

Finite element modelling and indirect tensile strength of SBS and CR modified asphalt mixtures
Publication Name: Discover Applied Sciences
Publication Date: 2025-01-01
Volume: 7
Issue: 1
Page Range: Unknown
Description:
Different modifications in asphalt mixtures can be employed to improve the performance of asphalt pavements in terms of rutting and fatigue damage resistance enhancement. Performance of asphalt mixtures can be further enhanced with the use of different proportions of modifiers added to bitumen, however the optimum proportion of the modifiers added require further experimentation in terms of indirect tensile strength of asphalt mixtures. This research consists of selection of different proportions of Polymer (SBS—Styrene Butadiene Styrene) and CR (Crumb Rubber) modifiers, that have been used in various amounts at 7% CR, 15% CR, 20% CR, 4% SBS, 7% SBS to base bitumen and the performance has been compared with base asphalt mixture. Indirect tensile strength for each mixtures type has been evaluated in the lab with varying rise time. Furthermore, stiffness moduli of each mixture have been evaluated at four different frequency values of 1.2 Hz, 1.9 Hz, 3.5 Hz and 5 Hz at 20 °C. Moreover, tensile strength for each mixture type and its progression with varying loading rates from 10 MPa/s to 70 MPa/s has been evaluated. A 2D finite element software, ABAQUS has been used to perform microstrain analysis for each mixture type. Fatigue and rutting damage models have been used to evaluate performance of each mixture type. Results show superior performance of SBS-7 and CR-20 mixtures in terms of rutting and fatigue damage resistance when compared to base asphalt. SBS-7 and CR-20 show 28% better performance in terms of fatigue damage resistance when compared to base asphalt. SBS-7 outperforms CR-20 in terms of rutting resistance by 22%.

A multigroup analysis focusing on assessing the green behavior of university employees for greening the workplace: a signaling theory perspective
Publication Name: Asian Education and Development Studies
Publication Date: 2025-01-01
Volume: Unknown
Issue: Unknown
Page Range: Unknown
Description:
Purpose – This study aims to examine the effects of Top Management Commitment to Greening the Workplace (TMCGW) on Employee Green Behavior (EGB) through the mediating role of Green Human Resource Management (GHRM) and employee Green Self-Efficacy (GSE) at universities in Bangladesh. In addition, it aims to find the differentiating impact of these relationships between academic and non-academic employees in the university. Design/methodology/approach – Researchers employed partial least squares structural equation modeling (PLS-SEM) in an empirical study grounded in a conceptual model derived from existing literature. The sample size is 288 Bangladeshi university employees: academics (171) and non-academics (117). The study is non-random, particularly convenient sampling with self-administered questionnaires for data collection. Findings – The overall sample’s findings have revealed that TMCGW positively affects GHRM, which in turn fully mediates the relationship with EGB. In the overall sample, TMCGW also positively affects employee GSE, which in turn fully mediates the relationship with EGB. In addition, in the academic sample, TMCGW has a positive influence on employee GSE, which in turn fully mediates the relationship with EGB; however, GHRM doesn’t mediate the relationship between TMCGW and EGB. Furthermore, in the non-academic sample, TMCGW positively affects GHRM, which in turn fully mediates the relationship with EGB, but TMCGW positively affects employee GSE, with GSE not mediating between TMCGW and EGB. The multi-group analysis also reveals that the differences are significant only in the relationship between GHRM and EGB. Originality/value – This study makes unique contributions in that TMCGW acts as an antecedent of GHRM, and employee GSE in the university, subsequently affecting EGB by applying signaling theory. The study also found a unique contribution of how this relationship varies between academics and non-academic employees in the university. This study helps university top management and HR professionals to develop appropriate policies to promote sustainable behavior among academics and non-academics.

Institutional quality and the environment–finance nexus: evidence from global economies
Publication Name: Environment and Development Economics
Publication Date: 2025-01-01
Volume: Unknown
Issue: Unknown
Page Range: Unknown
Description:
This study examines the intricate relationship between financial development, institutional quality and environmental efficiency. While financial development has the potential to support environmental sustainability, concerns remain regarding its unintended negative effects through unchecked economic expansion. The objective of this research is to investigate how financial development affects environmental efficiency and to assess the moderating role of institutional quality, particularly when financial development proxies reflect financial market accessibility and efficiency. Using a directional distance function within a stochastic frontier framework and incorporating multiple financial development indicators alongside measures of institutional quality, we find that financial development significantly reduces environmental inefficiency, with institutional quality strengthening this effect. These results highlight the importance of policy approaches that simultaneously enhance financial development and institutional quality. Furthermore, our findings support targeted initiatives such as promoting green finance, building institutional capacity and investing in research and data infrastructure to inform evidence-based policymaking for sustainable development.

DIGITALISATION IN ANGLING TOURISM: INTRODUCING NEW TECHNOLOGIES TO A TRADITIONAL TOURISM PRODUCT
Publication Name: Geojournal of Tourism and Geosites
Publication Date: 2025-01-01
Volume: 58
Issue: 1
Page Range: 42-51
Description:
In recent years, the use of digital solutions in tourism has accelerated and smart solutions are now used even in areas that are less technology-oriented, such as angling tourism. Angling itself and angling tourism seem rather traditional, definitely not tech-savvy activities, ones that can be categorised among the ecotourism or slow tourism products. It is not to say, however, that angling tourism does not evolve and is immune to the trends released in tourism. Recently there were huge changes in the regulation and organisation of angling in Hungary (and further changes are expected to come), which brought about a surge in the number of anglers in Hungary and the development of angling tourism. By now angling has become by far the hobby in Hungary done by the largest number of people; after a steady growth for decades, the number of registered anglers has by now reached almost one million persons, i.e. approximately ten per cent of the Hungarian population are anglers (and so potential target group of angling tourism), which makes the investigation of the topic of angling tourism really important – not to mention the fact that not only domestic but also inbound angling tourism is characteristic of Hungary. Among the changes, in 2019 the electronic support of angling administration was launched through the so-called HORINFO system run by MOHOSZ, the Hungarian National Angling Association. This paper summarises the changes and their consequences, explores the current digitalisation of angling tourism, its benefits, and examines the acceptance of new technologies by anglers. The results of the research show that the digitalisation and the introduction of new technologies accelerated during the Covid-19 epidemic, but their adoption by angling tourism has been slower. The study shows the importance of digitalisation in monitoring the environmental pillar of sustainability and the interventions needed. The study also provides a thorough investigation of the Hungarian and international literature of angling tourism, rather deficient to date, and gives recommendations on the further development of the HORINFO system. The significance of the issue is enhanced by the fact that Hungary now has a National Angling Development Strategy to strategically found further angling tourism developments.

A systematic review of female entrepreneurship using co-word and main path analyses
Publication Name: Quality and Quantity
Publication Date: 2025-01-01
Volume: Unknown
Issue: Unknown
Page Range: Unknown
Description:
The objective of this paper is to provide a thorough examination of the developmental trajectory of female entrepreneurship research in order to address the lacuna in the literature. The study employs a combination of co-word analysis and main path analysis (MPA) to conduct a systematic review of the citation network of female entrepreneurship research. This methodology facilitates the identification of dominant themes and foundational works, thereby mapping the gradual diffusion of knowledge throughout the field. The results indicate that critical themes, including the role of social networks in empowering female entrepreneurs, gender biases, access to finance, and entrepreneurial motivation, are present. The MPA delineates the manner in which early works concentrated on gendered challenges, while more recent research has explored topics such as innovation, work-life balance, and microfinance in developing economies. Furthermore, the study underscores emerging trends, including the influence of digitalization and institutional barriers on entrepreneurship. This study is the first to integrate co-word analysis with MPA in the context of female entrepreneurship, thereby offering a comprehensive and innovative perspective on the field’s evolution. In doing so, it provides valuable insights into the evolving research landscape, emphasizing critical gaps and suggesting promising areas for future investigation. This method establishes a precedent for the implementation of more data-driven reviews in the field of entrepreneurship research.
