Článek Omezený přístup peer-reviewedpostprint Theorems for Boyd-Wong Contraction Mappings on Similarity Spaces(MDPI, 2023) Rozinek, Ondřej; Borkovcová, MonikaIn this article, we introduce novel fixed point results for Boyd-Wong-type contraction mappings within the framework of similarity spaces, which have broad practical applications. The development of these results extends the classical theory of Boyd-Wong contractions by exploiting the unique structure and properties of similarity spaces. We provide an in-depth examination of the derived contractions, establishing conditions under which fixed points exist and are unique. In the latter part of the paper, we illustrate the applicability and effectiveness of the proposed results with representative examples.Konferenční objekt Omezený přístup peer-reviewedpostprint Social media and online behaviour among high school and university students(Slezská univerzita v Opavě, 2023) Kantorová, Kateřina; Klepek, MartinThe purpose of this paper is to describe the behavior of young people in the social media environment. The method chosen for data collection was a questionnaire survey on a representative sample of 1,706 valid respondents from Czech Republic. We used chi-square, analysis of variance, and factor analysis to explain relationships in data. Besides social media popularity ranking, our results showed that the more time respondents spend on the internet, the more social media brands they use. We also inspected the applicability of duplication of a purchase law in the social media context. Data showed that popular modes of communication among students include photos and texts followed by a video. Additionally, we found a similar use of social media among students and their parents. Last, with the use of exploratory factor analysis, we concluded that social media varies according to the content users go to it for, which carries implications for marketing communication strategy.Konferenční objekt Omezený přístup peer-reviewedpostprint The Importance of Interchange Terminals between Public Transport Subsystems on the Outskirts of City: Case Study Pardubice(Kaunas University of Technology, 2023) Baran, Filip; Heřmánková, AndreaThe paper focuses on the issue of public transport interchanges on the outskirts of city. Public transport terminals located on the outskirts of cities serve to create nodal points of transport connecting regional and city subsystems of public transport. The construction of new terminals in the existing transport network requires a detailed analysis of the operational concept of all modes of transport to be served by the terminal. In the city of Pardubice (Czech Republic), a new public transport terminal is being considered in the northwest part of the city outside the walking distance from the city centre. Two sites are proposed (Rosice nad Labem and Semtín) adjacent to the railway stations. The Rosice nad Labem site has a better connection to rail transport (2 lines; both long-distance, and regional segment), but no connection to urban public transport. The Semtín site, on the other hand, has a connection to the trolleybus backbone of the urban public transport, but there is only one railway line and only regional segment. It is therefore necessary to assess the situation comprehensively and choose the more suitable from the given locations. The key is to assess the sensibility of interregional transfers to urban transport to reach destinations within the city. The aim of this paper is to evaluate the suitability of the location of considered public transport terminal in the northwest part of the city of Pardubice. The evaluation will be based on traffic assignment methods taking part of four step transport demand modelling.Článek Omezený přístup peer-reviewedpostprint Perception, Self, and Zen: On Iris Murdoch and the Taming of Simone Weil(MDPI, 2023) Caprioglio Panizza, SilviaHow do we see the world aright? This question is central to Iris Murdoch's philosophy as well as to that of her great source of inspiration, Simone Weil. For both of them, not only our action, but the very quality of our being depends on the ability to see things as they are, where vision is both a metaphor for immediate understanding and a literal expression of the requirement to train our perception so as to get rid of illusions. For both, too, the method to achieve this goal is attention. For both, finally, attention requires a dethronement of the self, considered as the source of illusion. In this paper I investigate what moral perception means for each of these philosophers and how it operates through attention and its relationship with the self. I will show that, despite many striking similarities, Murdoch's project does not equal 'Weil minus God', but offers a different concept of the self, a different understanding of its removal, and therefore a different picture of attention and moral perception. In evaluating both views, I will gesture towards a third way represented by Zen Buddhism, which both philosophers variously consider but do not embrace.Článek Omezený přístup peer-reviewedpostprint Jak se hodnotí kvalita historikovy vědecké práce (Evaluace výsledků české historické vědy podle Metodiky17+ za léta 2016-2020)(2023) Vorel, PetrStudie se zabývá genezí procesů hodnocení výsledků vědy a výzkumu v oblasti historie v České republice.

V korespondenci byl reflektován především život žen, které obklopovaly kazatele (manželky, matky, sestry), ale také život ostatních příslušnic evangelických sborů. Dopisy zachycují různé aspekty každodenního života ženy, především rodinný život, vztah k dětem, vztah k manželovi, kontakty s příbuznými či běžné denní povinnosti v domácnosti. Jsou však také dokladem toho, jaký postoj měli k ženám muži, kteří o nich psali, a jak sami charakterizovali jejich postavení a život.Článek Omezený přístup peer-reviewedpostprint The Watershed of 1840: The Rise of International Insecurity and the Origins of Italian Moderate Nationalism(2023) Šedivý, MiroslavIn 1840 the international crises and territorially limited armed conflicts in Europe and overseas gave rise to or at least fueled feelings of deep mistrust, pessimism, and fear among a considerable number of Europeans toward the unsettled international situation, provoking across Europe a transnational debate about stability and justice in international affairs and the prospect for peace, all of which were usually seen as very insecure. This widespread and intensive public reaction to what was regarded as external threats if not to the general peace then at least to the security of European countries continued beyond 1840. Through the presentation and analysis of the response in the bourgeois public sphere to international insecurity in the example of the origins of moderate Italian nationalism, this essay reveals the strong influence of international affairs on how Europeans viewed justice and security in the mid nineteenth century.Článek Omezený přístup peer-reviewedpostprint Výchovné štýly v rodinách zo sociálne znevýhodneného prostredia(2023) Škoviera, Albín; Veselá, EliškaPríspevok sa zameriava na tri oblasti: charakteristiku súčasnej rodiny, kategorizáciu výchovných štýlov a zhody/ rozdiely v preferenciách výchovných štýlov v bežných rodinách a v rodinách zo sociálne znevýhodneného prostredia.Článek Omezený přístup peer-reviewedpostprint White striping, woody breast and spaghetti meat: Cooccurrence and relationship with breast fillet weight in big broiler chicken flocks(Česká akademie zemědělských věd, 2023) Valenta, Jaroslav; Siddique, Aftab; Tumova, Eva; Slavíček, Ondřej; Morey, AmitThe present study aimed to determine the incidence and coincidence of white striping (WS), woody breast (WB) and spaghetti meat (SM) in raw chicken breast meat (n = 300) collected 3-3.5 h post mortem from commercial broiler flocks (Ross 708 males, 56 days of age). The fillets were scored for the occurrence and severity of WS, WB and SM using visual and tactile methods, and the relationship between myopathies and breast weight was evaluated. A total of 88% of samples (out of 300) had either one or a combination of three myopathies, leaving only 12% without any myopathies. Approximately 29% of the fillets had only one myopathy present, with 59% of the samples demonstrating the cooccurrence of breast myopathies. In the present study, 47.7% of WB samples also exhibited WS, while the cooccurrence of WB and SM was exhibited in 14.7%. Based on binomial logistic regression, an increase in WB scores decreases the odds that the fillet may be affected by SM myopathy. No association was found between SM and fillet weight. Multinomial logistic regression showed that the weight of breast fillets was positively associated with WB1 (P = 0.011), WB2 (P < 0.001), and WB3 (P < 0.001). Furthermore, positive associa-tions were found between WS1 and WB3 (P = 0.004) as well as between WS2 and WB3 (P < 0.001). The percent-age distribution changes of each WB and WS myopathy score were used in relation to the 10 weight groups. The percentages of WB3 increased and WB0 decreased as the average fillet weight increased. Regarding linear regres-sion, these results exhibited a positive linear relationship for both WB (R2 = 0.91, P < 0.001) and WS (R2 = 0.71, P = 0.002) myopathy with fillet weight. A high prevalence of myopathies was observed. The incidence of severe WB categories and the overall high cooccurrence rate are alarming.Článek Omezený přístup peer-reviewedpostprint Enhanced prediction of parking occupancy through fusion of adaptive neuro-fuzzy inference system and deep learning models(2023) Elomiya, Akram; Křupka, Jiří; Jovčić, Stefan; Simic, VladimirWhile predicting parking occupancy is crucial for managing urban congestion, existing models often exhibit gaps in accuracy, uncertainty handling, and integration potential. This study introduces an innovative combination of adaptive neuro-fuzzy inference system (ANFIS) and deep learning (DL) techniques to address these shortcomings. Specifically, ANFIS is utilized for its proficiency in uncertainty representation via fuzzy set theory, whereas DL models excel in automatic feature learning, non-linear modeling, and identifying long-term dependencies in time-series parking data. By integrating ANFIS with recurrent neural networks (RNN), long short-term memory (LSTM), and gated recurrent units (GRU), we formulated the ANFIS-RNN, ANFIS-LSTM, and ANFIS-GRU fusion models, testing them on real-world parking datasets. Subsequent experiments highlighted the dominance of these fusion models over individual and benchmark counterparts. ANFIS-RNN achieved a 30.61% improvement in MSE, 16.70% in RMSE, 21.21% in MAE, 21.58% in MAPE, and a 1.03% elevation in R2 over the standalone RNN. The ANFIS-LSTM surpassed LSTM by 34.04% in MSE, 18.76% in RMSE, 26.16% in MAE, 27.71% in MAPE, with a 1.04% R2 increment. ANFIS-GRU exceeded GRU metrics by 27.54% in MSE, 14.85% in RMSE, 19.27% in MAE, 20.01% in MAPE, and boosted R2 by 1.03%. These outcomes underline the potential of integrated models in refining prediction precision. By leveraging the combined strengths of ANFIS and DL, this research offers a significant leap in parking occupancy forecasting. Its implications extend to data-centric urban planning and traffic regulation, marking a pivotal step for future endeavors in hybrid predictive modeling incorporating soft computing and deep learning paradigms.
