Public Law Liability of the Financial Market Supervisor

Michal Janovec János Kálmán

Publication Name: Journal of Risk and Financial Management

Publication Date: 2024-06-01

Volume: 17

Issue: 6

Page Range: Unknown

Description:

This article deals with the liability of the supervisory authority of the financial market. It could be questioned whether the supervisory authority, as the public authority, is liable for the supervisory performance. If the answer is yes, then the question is what kind of liability could be found and if any special conditions (prerequisites) are needed. In general, there could be two lines of public liability found. One is systemic liability for the safe financial market—e.g., financial market stability. The other perspective is individual liability for damages caused by unlawful administrative procedure or maladministration, where unlimited strict liability is granted. This kind of liability might be widely questioned, especially when the central bank is the supervisory authority, like in the Czech Republic, Slovakia, Hungary, and other EU member states. This article aims to evaluate the liability of the supervisory authority in the Czech Republic and Hungary concerning the European level of such liability.

METAPHORS IN TOURISM PROMOTION: A CASE STUDY OF A THAI VILLAGE AND THE BEEHIVE CONCEPT

Janka Sára Tóth Anikó Makkos Chin Ling Tsai

Publication Name: Geojournal of Tourism and Geosites

Publication Date: 2025-01-01

Volume: 60

Issue: Unknown

Page Range: 1128-1135

Description:

Metaphors are effective tools in tourism promotion, simplifying complex local features for tourists to appreciate. Sustainable tourism, by encouraging responsible habits, allows travelers to engage in environmental conservation while immersing themselves in local cultures. In this context, the primary aim of the research was to seek ways of promoting the unique features of Ban Nong Bua, a Thai village, while addressing global sustainability issues. A further aim was to develop educational material that would make sustainability attractive to local young children and familiarize them with local sustainability practices. During an 8-day stay, a multicultural team conducted action research through observations, interviews and interactions with local people with a focus on sustainable livelihood and tourism promotion. The fieldwork was complemented by regular brainstorming sessions, during which the concepts and plans that led to the final research product were developed based on the material collected and personal experience. The result of the research is the beehive metaphor as a conceptual framework that highlights the harmony and sustainable practices of the local community. The further result of the research is the creation of a booklet for both tourists and local children. On one hand, for tourists, the booklet provides an engaging introduction to the seaside village of Ban Nong Bua, enhancing its appeal as a sustainable destination. It is a complex metaphor that represents the way of life of the inhabitants of the settlement on several levels, such as the close relationship with water, the use of local resources, the division of labor, the high degree of social organization, cohesion and connectedness, or dancing as a specific manifestation of communication. Bees can also be seen as a symbol of sustainability. On the other hand, for local children, it serves as an English language educational tool, fostering an appreciation of sustainable practices through an interactive format. Although the short-term impact of the booklet cannot be measured, the research illustrates how tools such as metaphors can achieve multiple goals in sustainable tourism and sustainability education. The research promotes cross-cultural understanding, supports community sustainability and demonstrates the value of metaphor in tourism promotion. Future research could further explore the use of metaphors in tourism marketing and sustainability education.

Computer tomography based reconstruction of metal matrix syntactic foams

Ibolya Zsoldos Sz Papp I. Kozma G. Dorogi

Publication Name: Periodica Polytechnica Mechanical Engineering

Publication Date: 2014-01-01

Volume: 58

Issue: 2

Page Range: 87-91

Description:

In order to create 3D (three-dimensional) models for finite element calculations it is necessary to reconstruct the structure of metal foam composites reinforced by hollow ceramic spheres. A new algorithm was developed for this reconstruction work. This algorithm is based on the investigation of sphericity of the shapes found on CT (computer tomograph) layer records. Using this algorithm a 3D CAD (computer aided design) model of acceptable precision can be constructed.

The Forerunner UAV Concept for the Increased Safety of First Responders

Antal Hiba Ádám Kisari Mihály Nagy Istvan Drotar Attila Gáti Péter Bauer Balázs Lattes

Publication Name: International Conference on Vehicle Technology and Intelligent Transport Systems Vehits Proceedings

Publication Date: 2021-01-01

Volume: 2021-April

Issue: Unknown

Page Range: 362-369

Description:

This paper proposes a novel Forerunner UAV concept to increase the safety of first responders by monitoring the road in front of their emergency ground vehicle (EGV) and notifying the driver about any violation of his/her right of way or approaching danger. The developments are conducted in an R&D project in Hungary. The proposed UAV for the planned urban demonstration is a hexacopter with triple redundant architecture applying a gimbaled camera to monitor the surroundings. In the cooperative control of the EGV and UAV the UAV must fly in front of the EGV which is possible through wireless communication of route data and velocity. Besides the real system a computer simulation representation is also applied including CARLA and Matlab to make exhaustive tests of the system capabilities. Increased attention is devoted to the possible wireless communication solutions as these are safety critical parts of the system. The article ends with the lists of planned simulation and real test scenarios to evaluate the system.

Psychometric Validation of the Modified, Short Version of the Problematic Pornography Consumption Scale in Serbian

Beáta Bőthe Aleksandar Vujić Marija Volarov Nikolina Kuruzović Slavica Adamović Zdravković Attila Szabo

Publication Name: Sexual Health and Compulsivity

Publication Date: 2025-01-01

Volume: 32

Issue: 2

Page Range: 105-128

Description:

Pornography is used worldwide, and 3% of individuals may experience problematic pornography use (PPU, i.e. poorly controlled use resulting in significant distress and negative consequences). Therefore, instruments gauging PPU are needed in nation-specific languages. This study aimed to validate a modified version of the Problematic Pornography Consumption Scale-6 (PPCS-6) in the Serbian language among 1413 adults (52.9% males) aged from 18 to 54 (Mage = 24.96, SD = 4.46). Exploratory factor analysis on the sample’s random half yielded a single factor explaining 43% of the total variance. Confirmatory factor analysis on the sample’s other half revealed an acceptable model fit. Internal consistency (Cronbach’s alpha) was acceptable. The scale exhibited configural and partial metric invariance across genders and convergent validity. Latent profile analysis identified that 8.1% of the participants were at risk of experiencing PPU. In comparison, this value was 9.6% based on a calculated cutoff score (≥ 19) with acceptable values (.69 and.96) of sensitivity and specificity. To conclude, the Serbian modified version of the PPCS-6 appears to be a valid and reliable scale for screening PPU.

Relationship between direct and maternal genetic effects on weaning weight of Limousin and crossbred beef calves

Szabolcs Bene Eszter Szabó Márton Szűcs Judit Márton Ferenc Szabó

Publication Name: Czech Journal of Animal Science

Publication Date: 2021-01-01

Volume: 66

Issue: 7

Page Range: 262-270

Description:

Population genetic parameters, direct and maternal breeding value, genetic trend in the weaning weight of Limousin beef cattle calves were estimated in the period 1992–2019. Data of 19 764 calves (15 437 purebred Limousin and 4 327 crossbred) were computed. Crossbred calves were sired by Limousin breeding bulls from Simmental dams. Calves in question came from 37 herds and from 240 sires in Hungary. DFREML and MTDFREML software was used for the estimation of population genetic parameters, BLUP animal model for breeding value estimation. Weighted linear regression model was used for describing genetic trends. The maternal heritability (h2m ± SE = 0.29 ± 0.03; 0.32 ± 0.10) was approximately half of the direct heritability (h2d ± SE = 0.63 ± 0.05; 0.68 ± 0.12). The direct maternal covariance is negative, the direct maternal genetic correlation coefficients (rdm ± SE = –0.80 ± 0.03 and –0.96 ± 0.07) are strong negative. The Spearman rank correlation between direct and maternal breeding value in purebred population is moderate and negative (rrank = –0.33; P < 0.01), in crossbred population it is strong and negative (rrank = –0.99; P < 0.01). According to direct and maternal breeding values of sires the genetic trend of the weaning weight of purebred and crossbred Limousin calves appeared stagnant during the examined period (b = +0.01 kg/year to +0.19 kg/year).

Effect of pH, Carbonate and Clay Content on Magnesium Measurement Methods on Hungarian Soils

Csaba Centeri Renato Kalocsai Márton Vona Zsolt Biró Viktoria Vona Tamás Szakál István Mihály Kulmány Sándor Zsebő Lajos Kubina Zsolt Giczi

Publication Name: Soil Systems

Publication Date: 2024-06-01

Volume: 8

Issue: 2

Page Range: Unknown

Description:

More exact information on soil nutrient management is crucial due to environmental protection, nature conservation, decreasing sources for mining, general precaution, etc. Soil magnesium (Mg) analytical methods of potassium chloride (KCl), Mehlich 3 (M3), water (WA) and cobalt hexamine (CoHex) extractions are compared with an elemental analysis and X-ray fluorescence (XRF) analysis. The ratio of the available to the total Mg content was calculated and compared on the whole dataset. The results showed that the linear regressions between all the pairs of Mg content measurement methods were significant. The linear relationship between the KCl and CoHex methods has the highest determination coefficient (R2 = 0.96), followed by WA–M3 (R2 = 0.68), M3–CoHex (R2 = 0.66) and M3–KCl (R2 = 0.60). The M3 solution demonstrated a greater capacity for extracting Mg from the soil. The second part is the analysis of the influence of CaCO3, pH, soil texture and clay content on the measurable magnesium content of soils. It was established that the extraction methods, the soil and the classification method of the soil properties affect the evaluation. These results may help through the nutrient replenishment and the melioration of soils. These results can help the examination of mineral nutrients, especially the Mg uptake.

Characterisation of hardening performance of quenchants by integrated numerical method

Imre Felde Tamás Réti

Publication Name: International Heat Treatment and Surface Engineering

Publication Date: 2008-06-01

Volume: 2

Issue: 2

Page Range: 55-59

Description:

An integrated numerical technique for evaluation of hardening performance of cooling media applied for steel quenching is outlined. The newly developed method is based on the specific processing of measured time-temperature samples performed as a result of cooling curve tests. The heat transfer coefficient as a function of surface temperature characterises the heat transfer during cooling and is calculated using an iterative inverse algorithm. The heat transfer coefficient is used for calculation of the microstructural constituents and the hardness profile of cylindrical samples of arbitrary diameter. The hardening performance of media is evaluated by the estimated hardness of specimens obtained by heat treatment. © 2008 IHTSE Partnership.
