Financial Supervision for the Green Transition: Comparative Insights From the EU, Hungary, and Singapore
Publication Name: Thunderbird International Business Review
Publication Date: 2026-05-01
Volume: 68
Issue: 3
Page Range: 357-366
Description:
This paper examines how financial supervisory authorities integrate Environmental, Social, and Governance (ESG) objectives into their regulatory mandates amid the accelerating green transition. It aims to understand how institutional variation shapes supervisory strategies for sustainable finance. The study employs a qualitative, comparative case study design across three jurisdictions: the European Union, Hungary, and Singapore. Drawing on regulatory theory and document analysis, this study identifies the key institutional logics, instruments, and governance mechanisms through which ESG considerations are embedded in financial supervision. The analysis reveals three supervisory models: the EU's rule-based legal harmonization through taxonomy and disclosure mandates, Hungary's responsive approach led by the central bank using soft tools and innovation, and Singapore's principle-based framework emphasizing strategic guidance and market collaboration. These pluralistic pathways highlight that ESG integration is shaped by legal mandates, legitimacy concerns, and adaptive governance. This study provides insights to policymakers and supervisors seeking to align financial oversight with sustainability objectives. This emphasizes the importance of institutional flexibility, regulatory legitimacy, and hybrid governance in designing effective ESG supervision frameworks. This study contributes to the literature on sustainable finance and regulatory governance by offering a comparative perspective on how financial supervision evolves in response to ESG risks. It advances a novel typology of supervisory models that can inform future regulatory design and policy debates.

Selling and pricing practices in the direct sales of producer’s raw cow’s milk
Publication Name: Elelmiszervizsgalati Kozlemenyek
Publication Date: 2016-09-30
Volume: 62
Issue: 3
Page Range: 1190-1223
Description:
Among our objectives were the presentation of the most well-known sales channels of raw milk, sales practices and also the technological level used, as well as the examination of the issues related to the pricing, critical points and challenges of the direct sales of raw cow’s milk. Our observations and samplings were performed at 21 direct sales locations of eight Budapest districts over 13 months, from June 2013 through June 2014. Based on the results, it can be stated that, in the area studied, the sale of raw milk is realized through three main sales channels: markets (market halls), self-service systems (milk vending machines, refrigerated store containers) and different forms of mobile sales (tankers, regional home delivery system of producers). Further marketing practices can be distinguished within the different sales channels, where one can find the most primitive practice, the one without cooling, the traditional one and one that can be considered modern even when compared to Western European practice. The theoretical possibility to sell high quality raw milk was available for all sales channels, but the level of sales – especially from hygienic and technological viewpoints – ranged widely. Based on changes in the sales price of raw milk, and its correlation with wholesale buying prices and pasteurized milk prices, it can be assumed that market prices and supply and demand are closely followed by shareholders of the market. Analyzing the mutually influencing effect of the prices of sellers located close to each other (e.g., in the same market), it could be concluded that the majority of them used a follower pricing strategy. Results of the price/quality ratio indicate a disordered state and arbitrary pricing. The application of proper milk procurement, management and sales approaches would improve, in itself, processes that take place at the critical locations, described under the headings human factors, work organization, operation, maintenance and repair, quality aspects, packaging and labeling.

Health capital in the 'cis-elbanian' vs. 'trans-elbanian' grand regions: Frame disputes about framing ambiguities and misframings
Publication Name: European Journal of Mental Health
Publication Date: 2009-06-01
Volume: 4
Issue: 1
Page Range: 3-26
Description:
The present study forms an operational variation of the task undertaken in the outlook paragraph of the authors' earlier article to study with the help of the Sense of Coherence (SOC) as a group property, the health and general well-being of the Hungarian national community (in an international comparison). With Hungary being the only Eastern Central European ('Trans-Elbanian') country joining the EU-project with the title Corporate Culture and Regional Embeddednes (CURE), we Hungarians tried to help achieve this goal by making the following proposal to the researchers of the five Western-European ('Cis-Elbanian') countries partaking in the project: the drastically different Health Capital level of the Grand Regions situated on the two sides of the Elbe-Leitha boundary ('centrum versus semi-periphery') should be inserted as a control variable into the original research model of the project, which has propounded the hypothesis that the interaction between the organisational culture of the corporations operating in the sample region of the individual countries and the national culture of the respective regions has had an impact on the development of the region. We have presumed that this enormous difference between the Health Capital levels can bring to light the true underlying historical-social-economical impact factors which appear to be 'cultural' when approached for the first time. The leadership of the project allowed the Hungarian team to check, beyond the qualitative research design of the project, with the quantitative method of the research, the model variation enriched with a Health Capital variable. The conclusive results thus gained anticipate an affirmation of the results achieved in the original qualitative variation of the project design and may serve as an example for the whole research team to also implement an internationally exact investigation of the effect of the Health Capital as a control variable of the cultural impact in a possible follow up. The present study displays the first, pilot study results of this research undertaking, to be implemented in our country within the frame of the CURE project, and to be transferred into the international comparison if it proves successful. These preliminary results illustrate the interdependency of the cultural dimensions and the Health Capital apprehended in a salutogenic cross section. © 2009 Akadémiai Kiadó, Budapest.

Manufacturing and Assembly Variability in Electric Drivetrains: Impacts on NVH Performance—A Review
Publication Name: World Electric Vehicle Journal
Publication Date: 2026-05-01
Volume: 17
Issue: 5
Page Range: Unknown
Description:
Considerable progress has been made in predicting nominal NVH behavior in electric drivetrains, but the acoustic scatter observed across manufactured units remains insufficiently understood. In practice, nominally identical drive units may still exhibit noticeably different tonal behavior because small deviations in gears, shafts, bearings, fits, centering features, or assembly phase modify the excitation, transfer, and radiation mechanisms of the system. This review examines how manufacturing and assembly variability influences NVH performance in electric drive units and e-axles, with particular focus on the rotor–shaft–gear–bearing–housing system. Unlike broader EV NVH reviews, the present work focuses specifically on variability-induced acoustic scatter and its propagation along the drivetrain NVH generation and transmission path. To support transparency and consistency, the literature search and selection process followed a structured, PRISMA-inspired approach across Scopus, Web of Science, Google Scholar, and SAE Mobilus for the 2015–2026 period. From 387 identified records, 50 studies were retained after duplicate removal, screening, and full-text assessment. The selected literature was synthesized into eight thematic categories: imbalance; run-out and eccentricity; bearing clearance and preload; spline and pilot centering; thermal effects; phase indexing; transmission error and sidebands; and end-of-line NVH diagnostics. The reviewed literature shows that manufacturing- and assembly-induced deviations can significantly alter transmission error, sideband structure, shaft-order content, and final tonal response, even when individual components remain within nominal tolerance limits. Beyond synthesizing the evidence base, the review organizes existing modeling and diagnostic practices into a structured framework for variability-aware NVH assessment, based on explicit deviation parameterization, hierarchical model fidelity, intermediate excitation metrics, thermal-state awareness, and closer integration with production and measurement data. Overall, the findings support a shift from nominal NVH assessment toward robustness-oriented, production-representative interpretation and future prediction of acoustic scatter in electric drivetrains.

Biomechanical Characteristics of adolescent Cervical Forward Flexion analyses Based on the Finite Element Method
Publication Name: Advances in Transdisciplinary Engineering
Publication Date: 2024-01-01
Volume: 59
Issue: Unknown
Page Range: 479-485
Description:
Adolescents' poor sitting posture is hazardous, and long-term poor sitting posture can lead to elevated incidence of neck pain. This study investigated the biomechanical attributes of the adolescent neck to mitigate the hazards of poor sitting posture and to provide recommendations for adolescent neck health; The C1-T3 images of the cervical region were acquired from the same subject in normal posture as well as in cervical forward flexion posture with a gap between scans of 0.50mm, and the CT images were transformed into DOCM format in Mimics for subsequent 3D modelling. A finite element (FE) model of the C1-T3 normal posture as well as the cervical forward flexion posture was established. In order to investigate the differences between the two models' cervical vertebrae and intervertebral disc stress, the stress and intervertebral disc strain of the two models were compared. A standard cervical spine model and a FE model for cervical forward flexion were created and validated. The range of motion, vertebral body, and intervertebral disc stresses were examined for both models. Comparison with previous literature confirmed the accuracy of the forward flexion model, showing consistent results with the normal cervical spine model. In the forward flexion direction, the model demonstrated increased stresses in the vertebral body, particularly in the anterior side, surpassing those in the normal model. The maximum stress in the vertebral body reached 5.99 MPa, and in the intervertebral disc, it was 1.02 MPa. Overall, stresses in the anterior cervical flexion model exceeded those in the normal model. Poor neck posture leads to more pronounced stress concentration phenomena in the vertebral body, increasing peak pressure in the vertebral body, in addition increasing com-pression on the intervertebral discs, leading to an increased risk of neck pain risk as well as cervical dysplasia, and therefore excessive forward flexion of the cervical spine in adolescents should be avoided.

Polyaromatic hydrocarbons (PAHs) in the water environment: A review on toxicity, microbial biodegradation, systematic biological advancements, and environmental fate
Publication Name: Environmental Research
Publication Date: 2023-06-15
Volume: 227
Issue: Unknown
Page Range: Unknown
Description:
Polycyclic aromatic hydrocarbons (PAHs) are considered a major class of organic contaminants or pollutants, which are poisonous, mutagenic, genotoxic, and/or carcinogenic. Due to their ubiquitous occurrence and recalcitrance, PAHs-related pollution possesses significant public health and environmental concerns. Increasing the understanding of PAHs' negative impacts on ecosystems and human health has encouraged more researchers to focus on eliminating these pollutants from the environment. Nutrients available in the aqueous phase, the amount and type of microbes in the culture, and the PAHs' nature and molecular characteristics are the common factors influencing the microbial breakdown of PAHs. In recent decades, microbial community analyses, biochemical pathways, enzyme systems, gene organization, and genetic regulation related to PAH degradation have been intensively researched. Although xenobiotic-degrading microbes have a lot of potential for restoring the damaged ecosystems in a cost-effective and efficient manner, their role and strength to eliminate the refractory PAH compounds using innovative technologies are still to be explored. Recent analytical biochemistry and genetically engineered technologies have aided in improving the effectiveness of PAHs' breakdown by microorganisms, creating and developing advanced bioremediation techniques. Optimizing the key characteristics like the adsorption, bioavailability, and mass transfer of PAH boosts the microorganisms' bioremediation performance, especially in the natural aquatic water bodies. This review's primary goal is to provide an understanding of recent information about how PAHs are degraded and/or transformed in the aquatic environment by halophilic archaea, bacteria, algae, and fungi. Furthermore, the removal mechanisms of PAH in the marine/aquatic environment are discussed in terms of the recent systemic advancements in microbial degradation methodologies. The review outputs would assist in facilitating the development of new insights into PAH bioremediation.

Specific heart rate values of 10-12-year-old physical education students during physical activity
Publication Name: Journal of Physical Education and Sport
Publication Date: 2016-09-01
Volume: 16
Issue: 3
Page Range: 800-805
Description:
Students who participate in well-planned and structured physical education (PE) lessons engage in significantly higher levels of physical activity than children who do not. Heart rate monitoring a useful tool to help both students and teachers understand the efficiency of the physical activity. The purpose of this study was to analyze primary school children’s body compositions and heart rates when performing different types of physical activities (gymnastics, mixed activities, ball games, athletics, and games). The sample included 10-12-year-old primary school boys (N=46) and girls (N=63) from the university’s cooperating school. To estimate their body compositions, standard anthropometric techniques were used. Polar RS400 heart rate monitors were used to monitor the heart rate of each child during the main parts of different types of physical education lessons. There were no differences between the genders for the body composition or for the maximal heart rate values in the different PE content areas. The lowest heart rate was recorded during gymnastics (148 beat*min-1), and the highest values were detected during the game activities and athletics (164.60 and 163.83 beat*min-1. For the mixed activities and ball games, the heart rates ranged between 154.06 and 156.52 beat*min-1. Physical activities that result in higher heart rate values required a greater contribution and adaptation of the cardiovascular system. However, activities that elicit a lower heart rate likely focus more on skill learning and acquisition. This data can be used as a resource for physical education teachers when planning and structuring PE classes.
