Description:

Generative artificial intelligence is playing a significant role in the transformation of digital ecosystems by reinventing the processes of content generation, process automation, product innovation and customer experience. At the same time that these technologies are becoming more integrated into routine operations, the focus has shifted to the ethical and environmental consequences associated with their widespread application. An investigation of the operational sustainability associated with the generative artificial intelligence systems would be crucial, as it would provide information about how these systems match ideals such as efficiency, circularity and environmental responsibility. We explore how users understand and engage with sustainability principles, specifically lean, circular and green operational frameworks within generative artificial intelligence environments. We collect user reviews of 72 recently launched generative AI platforms from 2022 to 2024 and utilise advanced machine learning methods, including Word2Vec modelling, sentiment and regression analysis, to reveal how text datasets reflect customer perceptions. We find that the lean theme is the most prominent feature of operational sustainability, with the highest sentiment score, followed by the green and circular themes. Our findings show that there is a growing respect among the general public for artificial intelligence systems that exhibit responsible and efficient design.

ANALYSIS OF WELL-BEING AT WORK AND WORKING FROM HOME BASED ON THE RESULTS OF A SURVEY IN SLOVAKIA

P. Karácsony Angelika Czókolyová Monika Imreh-Toth Csaba Vandor

Publication Name: Economics and Sociology

Publication Date: 2025-01-01

Volume: 18

Issue: 3

Page Range: 160-174

Description:

The coronavirus outbreak at the end of 2019 can be cited as a trigger for several drastic consequences. In those years and since, the pandemic brought many changes for which the world was not prepared. The spread and increased prevalence of home-based work is one such consequence. The study of the relationship between working from home and well-being at work is one of the most researched areas in the field of economic psychology today. The main objective of this study was to investigate well-being at work in a Slovak sample and to explore its relationship with working from home. The research methodology was implemented in the form of an online questionnaire at the end of 2023. A total of 772 people participated in the survey. According to the research hypothesis, there is a significant correlation between the form of working from home and a higher average level of well-being at work. The results obtained confirmed the hypothesis that working from home has a positive impact on well-being at work. Furthermore, the results highlight the main risks of work from home in terms of 'home comfort' and 'work-life balance'. In conclusion, the research has shown both the advantages and disadvantages of working from home, and managers should strive to ensure that the well-being of employees is maximized in order to work effectively.

Integrating Artificial Intelligence into Fuzzy Decision Analytics: A Novel Approach to Mitigating Stereotype Threat in Sustainable Business Environments

Gergely Czukor Dragan Pamucar Hasan Dincer Serhat Yuksel Serkan Eti

Publication Name: Journal of Fuzzy Extension and Applications

Publication Date: 2025-06-01

Volume: 6

Issue: 2

Page Range: 371-390

Description:

Preventing the threat of stereotyping is critical for business performance improvements. Because of this situation, businesses must take the necessary precautions. However, these actions have an impact on cost increase for the businesses. The number of studies in the literature performing priority analysis for these factors is quite limited. This situation increases the need for a new study that prioritizes the analysis of these variables. Accordingly, this study aims to evaluate the factors against the stereotype threat in the sustainable business environment. An artificial intelligence model is implemented in the first stage to weigh the experts. In the following stage, selected criteria are evaluated with the help of T-Spherical fuzzy DEMATEL. Thirdly, a comparative analysis was performed using different values. Finally, selected industries are ranked by Spherical Fuzzy RATGOS with respect to the stereotype threat. The weights of the experts can be identified in the analysis process. This situation has a strong contribution to the effectiveness of the findings. It is concluded that training activities are critical to minimizing the threat of stereotypes in companies.

Rainfall duration and parameter sensitivity on flash-flood at a steep watershed

Katalin Bene Gergely Ámon

Publication Name: Pollack Periodica

Publication Date: 2023-07-11

Volume: 18

Issue: 2

Page Range: 54-59

Description:

The common feature of streams in steep sloping watersheds is that there is a significant change from base-flow to flash-flood; sometimes two or three orders of magnitude. In Hungary, these streams are usually ungauged, with lack of available data, and models. The watershed features both urban and natural land use conditions, but the main area is quite homogenic. This paper evaluates the impact of different model parameterizations, and rainfall duration on flash-flood events in the Morgó-creek watershed. The goal is to find the main parameters that can represent the uncertainty of a flash-flood sensitive area, and how the calibrated and determined parameters take effect on a model if these values are shifted on given intervals.

Page Range: Unknown

Description:

Behavioural addictions may negatively impact athletic performance and overall health. Little data exist on endurance runners. We conducted a cross-sectional survey study in endurance (≥21.1 km to 42.2 km) and ultra-endurance runners (≥42.2 km), screening for alcohol misuse, substance use (SU), gambling, and exercise addictions (EA) while assessing potential associated risk factors. Statistical analysis included descriptive statistics, the Kruskal–Wallis H-test with post-hoc Dunn´s test, a Multivariable Logistic Regression model, and a CatBoost Classifier, with model interpretability techniques such as Shapley Additive Explanations (SHAP) and Partial Dependence Plots (PDPs). Of 601 runners, 222 were females (37%); their mean age was 42.8±10.1 years; 28.6% screened positive for alcohol, 26.1% for SU, 18.1% for EA, and 8.0% for problematic gambling. SU was more prevalent among female runners (p = 0.02) and half-marathoners (p = 0.007), whereas gambling was more common among men (p = 0.02). Women reported higher EA than men (p < 0.001). Risk factors for alcohol misuse included younger age (25–33 years, p = 0.007), fewer workouts (p = 0.025), and higher income (p < 0.001). SU risk was associated with competition frequency (p = 0.011), injury-related absences (p = 0.002), and EA (p = 0.044). SU included caffeine, cannabis, nicotine, cocaine, ecstasy, and solvents. Gambling risk was associated with younger age (p < 0.001) and EA (p = 0.049). More workouts (p = 0.025) were related to higher EA. Based on these results, we recommend raising awareness, implementing broader screening programmes, and providing educational and support for athletes and staff.

Modification of Concrete Railway Sleeper Mix Design, Using a Hybrid Application of Steel Fibers

Guoqing Jing Farshad Astaraki Mohammad Siahkouhi Majid Movahedi Rad Sashka Uuganbayar Jun Wang

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2022-01-01

Volume: 19

Issue: 3

Page Range: 119-130

Description:

Concrete railway sleepers have been used for years without an update in production and design, to be compatible with demands for increasing train axle loads and speed. In the current research, concrete railway admixture is modified with consuming (0.5% straight-1.5% hooked), (1.5% straight-0.5% hooked) and (1% straight-1% hooked) steel fibers combinations. Three main mechanical experiments as compressive, flexural and splitting tensile strengths and fresh mortar “flowability” were performed. Results showed that the hybrid of 1% straight and 1% hooked steel fibers shows the optimal performance among other hybrid combinations. This hybrid admixture efficiently improves the compressive, flexural and splitting tensile strengths of the concrete railway sleeper mix design.

Description:

In this work, the hypselostomatid land snail genus Acinolaemus F.G. Thompson & Upatham, 1997 in Southeast Asia is revised. Characters based on which the genus was originally erected are thoroughly examined and evaluated. The genus is subdivided into six species groups based on similarities in shell surface sculpture and apertural barrier morphology. Four out of five species originally described in Acinolaemus, as well as species described from Vietnam and Cambodia are moved to Clostophis. Thirteen new species of Acinolaemus are described as follows: A. altus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. asper Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. atypicus Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. ferox Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. humilis Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. microcubus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. paucidentatus Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. profundus Gojšina, Auffenberg & Páll-Gergely, sp. nov., A. rugolabialis Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. simplex Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. singularis Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. solitus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. zed Gojšina, Hunyadi & Páll-Gergely, sp. nov. Thus, the total number of Acinolaemus species increases to 19, all inhabiting Thailand and Myanmar.
