The Influence of International Collaboration on the Scientific Impact in V4 Countries

Zsolt Kohus Márton Demeter Katalin Czakó Eszter Lukács László Kun Gyula Péter Szigeti

Publication Name: Publications

Publication Date: 2022-12-01

Volume: 10

Issue: 4

Page Range: Unknown

Description:

Several strategies are used by researchers and research facilities to increase their scientific production and consequent research quality. Bibliometric records show that coauthorship and the number of participating organizations in research publications are steadily increasing; however, the effect of collaboration varies across disciplines, and the corresponding author’s country appears to influence research impact. This finding inspired our research question for this study: How does international cooperation affect scientific impact, and does the affiliation of corresponding authors influence citation impact indicators at the level of individual publications? To this end, we provide a comparative evaluation of research articles published in Q1 journals among Visegrad Group countries (Czech Republic, Hungary, Poland and Slovakia) in Medical and Health sciences between 2017 and 2021. The study investigates the relationship between collaboration type (national vs. international) and scientific impact (impact factor of the journal and category normalized citation impact or research papers), as well as the impact of the country of the corresponding author’s affiliation on quantitative quality of individual papers. We show that Q1 research papers in international collaboration have a higher scientific impact than papers published in national partnerships. Moreover, the corresponding authors’ country of affiliation significantly affects scientific impact.

Lóránt Dávid Parikshat Singh Manhas Imre Varga Setiawan Priatmoko Al Fauzi Rahmat Prince Verma Rajashree Sutar

Publication Name: Journal of Infrastructure Policy and Development

Publication Date: 2024-01-01

Volume: 8

Issue: 12

Page Range: Unknown

Description:

The article aims to evaluate the participation of below-poverty-line local community in tourism-related business activity in Himalayan state of Uttarakhand. Further, this article addressed for those who work in the tourism sector. The study employs a mix of methods, including survey data from 500 respondents with a random sampling approach, using Analysis of variance (ANOVA) statistical tools for analysis, other methods were interviews and observations at six tourism sites in Garhwal and four sites in Kumaun. Our findings showed that there has declined in community participation in tourism development, due to the lack of economic benefits obtained in the tourism sector, many believe that the tourism sector does not provide much income growth for them and does not make a significant contribution to the development of their region. Moreover, lack of understanding is considered the basis for community’s inability to play an active role, and lack of stakeholders’ involvement in encouraging them to improve their economy and culture through the tourism sector. Ultimately, this research also underlines the existence of some efforts by tourism travel to encourage public trust, which can help reduce poverty and increase community trust in tourism development in their region.

Sight distance analyses for autonomous vehicles in Civil 3D

Dániel Miletics Khalil Khaska

Publication Name: Pollack Periodica

Publication Date: 2021-12-31

Volume: 16

Issue: 3

Page Range: 33-38

Description:

Nowadays, self-driving cars have a wide reputation among people that is constantly increasing, many manufacturers are developing their own autonomous vehicles. These vehicles are equipped with various sensors that are placed at several points in the car. These sensors provide information to control the vehicle (partially or completely, depending on the automation level). Sight distances on roads are defined according to various traffic situations (stopping, overtaking, crossing, etc.). Safety reasons require these sight distances, which are calculated from human factors (e.g., reaction time), vehicle characteristics (e.g., eye position, brakes), road surface properties, and other factors. Autodesk Civil 3D is a widely used tool in the field of road design, the software however was developed based on the characteristics of the human drivers and conventional vehicles.

Low-element FPGA beamforming: A ZCU102 demonstration of directed ultrasonic inspection

Dénes Varga Gábor Lencse

Publication Name: Journal of Electrical Engineering

Publication Date: 2026-04-01

Volume: 77

Issue: 2

Page Range: 139-147

Description:

This paper presents the design and implementation of a compact FPGA-based (Field-Programmable Gate Array) controlled ultrasonic transducer system. Our aim was to achieve ultrasound beam steering using three elementary ultrasonic transducers. The transducers generated a steerable beam through ultrasound interference, which was controlled by adjusting the phase differences between them. The system’s performance was demonstrated using a radar-style beamforming plot. Using elementary transmitters with an initial aperture angle of 50°-130°, an effective aperture angle of 74°-101° was achieved. The core of the device was implemented on a ZCU102 development panel, which had a considerable impact on the following development phase. Our proposed approach offers a compact and cost-effective solution for Non-Destructive Testing (NDT) systems; its applicability was demonstrated on a wood inspection example. Finally, potential directions for further development toward a fully functional device are discussed.

Exploring entrepreneurial phases with machine learning models: Evidence from Hungary

Áron Szennay Judit Csákné Filep Melinda Krankovits

Publication Name: Entrepreneurial Business and Economics Review

Publication Date: 2025-06-01

Volume: 13

Issue: 2

Page Range: 101-122

Description:

Objective: The article aims to explore the potential differences between the two phases of entrepreneurship, i.e., total early-stage entrepreneurial activity and established business, as defined by the Global Entrepreneurship Monitor (GEM). The study aimed to classify entrepreneurs using various machine learning models and to evaluate their classification performance comparatively. Research Design & Methods: Using the Hungarian GEM datasets from 2021 to 2023, we analysed a subsample of 964 entrepreneurs. Due to inconsistent results from traditional analyses (e.g., correlations, regressions, principal component analyses), we employed machine learning approaches (supervised learning classification methods) to uncover latent relationships between variables. Findings: The study utilized seven machine learning classification methods to examine the feasibility of grouping companies within the sample using Hungarian GEM data. Findings indicate that machine learning techniques are particularly effective for classifying businesses, although the performance of each method varies significantly. Implications & Recommendations: These results provide valuable insights for researchers in selecting methodologies to identify various business phases. Moreover, they offer practical benefits for market research professionals, suggesting that machine learning techniques can enhance the classification and understanding of entrepreneurial phases. Contribution & Value Added: The study adds to the existing body of knowledge by demonstrating the effectiveness of machine learning methods in classifying business phases. It highlights the variability in performance across different machine learning techniques, thereby guiding future research and practical applications in market research and entrepreneurship studies.

Financing of Agricultural Pensions on the European Continent

Andras Giday Tatay Tibor

Publication Name: Public Finance Quarterly

Publication Date: 2022-01-01

Volume: 67

Issue: 1

Page Range: 83-99

Description:

Supporting agriculture in Europe is important for many reasons: on the one hand, to secure food supplies, and on the other, to ensure the sustainability of rural lifestyles. But in recent decades, rural populations have also been affected by population ageing. Different agricultural pension schemes have been set up in European countries, taking into account the specificities of the agricultural sector. Pension funds have tended to be more important where the role of small farms was significant and the pension system was of the fully Bismarckian type. In general, they were not introduced where a 'kolkhoz system' existed in East-Central Europe before 1990. In our study we looked at the different forms that have been implemented. We have reviewed the changes that have taken place in recent decades and found that in some countries, states have supplemented contributions to pension payments by up to 75-85%. Our methodology involves document analysis and comparative assessment. We argue that it is worthwhile to encourage farmers to continue production on smaller farms by providing special sectoral support, career funding and pensions in order to meet social and environmental objectives.

Publication Date: 2024-01-01

Volume: Unknown

Issue: Unknown

Page Range: 405-409

Description:

Every society has its own characteristics, shaped from time to time by the various innovative, disruptive, but in any case, dynamically changing mechanisms that affect it most. In today's society, technological innovation plays a major role in the development of individuals and their abilities. Education is the most typical and obvious arena for shaping, developing, and preparing for the challenges of the future. As in the leading sectors, in the world of education, rapid responses and immediate reactions to change significantly increase the ability to achieve and maintain success and thus marketability. As a sector responsible for developing the competences of individuals, building knowledge and training professionals, education should seek to keep pace with trends and break with traditional approaches and methods, so that, in addition to incorporating technological developments, a renewed approach to organizational development and methodology is an important means of achieving the desired success and effectiveness. In the course of our work, we provide a summary insight into the project work of student groups who require up-to-date IT skills, use advanced IT tools, plan, and implement their web development workflows supported by database management, front-end planning and design, and back-end programming with a project management approach according to the latest trends, interpreting the advantages and disadvantages of working methods for success.

Terrorism with a «woman’s appearance»: Economic background and legal tools for forming a counteracting strategy

Eszter Lukács Roman Myroniuk Oksana Lehka Stanislava Myroniuk

Publication Name: Economic Annals Xxi

Publication Date: 2019-01-01

Volume: 177

Issue: 5-6

Page Range: 34-43

Description:

The authors have researched the phenomenon of female terrorism in the area of rational choice and economic benefit. Popular quotations «qui prodesse» and «сherchez la femme» are combined from these positions in the non-standard authors’ approach to understanding the motivational factors underlying extremist movements. It has been proved that the increase in the number of women in the ranks of terrorists is largely due to the so-called economic benefit factor for the terrorist acts organisers. The actions of a suicide bomber, in the broad sense, are predominantly based on a rational basis: the achievement of the last personal good - identity. The article presents the transformation of female terrorism in the historical perspective; actual conflicts and contradictions in international law and national legal systems, as well as false social attitudes and stereotypes complicating the fight against this dangerous social phenomenon. Data obtained from the social networks allows concluding that hundreds of women are now fighting in the ranks of militants in the East of Ukraine. At the beginning of the conflict, many of them hid their faces on personal pages on the Internet, hiding from their relatives a fact that they are hired killers. At the moment, most of them are proud of their participation in extremist groups, post their photos with weapons. Suicide terrorism of Muslim women and crimes committed by female militants in the East of Ukraine have one thing in common - the preparation and use of women as a living «weapon» by the extremist groups is cheaper either in terms of financial investments and costs for psychological brainwashing and military training. Based on the analytical data and identified patterns, we have argued the strategic directions of counteraction to female terrorism and have proved the following: mankind will be able to break this danger on the condition of a new, free of stereotypes way of thinking and coordinated efforts of the world community in all spheres of social life including economic, legal, socio- and cultural ones.

Comparison of railway track transition curves

Szabolcs Fischer

Publication Name: Pollack Periodica

Publication Date: 2009-12-01

Volume: 4

Issue: 3

Page Range: 99-110

Description:

There are no design parameters related to speeds exceeding 160 km/h in the effective Hungarian railway design rules. In the relevant international standard (ENV 13803) a similar speed limit is 300 km/h. This paper deals with the comparative of these regulations. Parameters of two transition curves used in Hungary and other used in Austria are determined. The importance of the new design parameters provided by ENV 13803 is assessed. It is demonstrated that the usability of the clothoide transition curves is unnecessarily restricted for the speeds v≤120 km/h in the Hungarian regulations. © 2009 Akadémiai Kiadó.
