Exploring Disinformation: The interplay of exposure, trust, and sharing

Disinformation, defined as false information deliberately created and communicated as true to influence beliefs or behavior, poses a growing threat to democratic societies and public discourse. This study examined patterns of disinformation exposure, trust, and sharing among adults in the Czech Republic—a small European democratic country. Using survey data from 3240 participants collected in June 2023, we investigated how sociodemographic factors relate to these dimensions of disinformation engagement.Findings show that older individuals, those with lower educational attainment, and women are more likely to trust disinformation. Prior exposure was strongly associated with increased trust in disinformation narratives, consistent with the familiarity effect described in prior research. Trust, in turn, was the strongest predictor of sharing behavior, suggesting that disinformation is often spread by individuals who genuinely believe it, rather than by deliberate deceivers.By combining real-world narratives with a standardized assessment framework, this study provides insight into who is most vulnerable to disinformation and why. These findings contribute to a deeper understanding of how disinformation circulates in the general population and which groups are most susceptible

Educational model for evaluation of airport NIS security for safe and sustainable air transport

One of the praxeological problems of safe and sustainable air transport (airfreight transport/air cargo, and air passenger transport) is the prevention and management of risks by competent staff, with the support of modern information and communication technologies. This paper presents an educational information model and software for the airport network and information systems risk assessment, primarily intended for aviation education and training of professionals for ensuring safe and sustainable air transport. The solution to the problem is based on the application of the fuzzy logic method in the air transport environment. Based on a fuzzy expert model, the selected scenario, and the input data established separately for airport assets by a group of 23 experts from aviation practice and a university, the following three assessments of airport network information system assets were constructed: Asset A2 (meteorological information systems) has an insignificant risk with an estimated 0.1162, and assets A1 (air traffic control and management (ATM), navigational aids and approach) and A3 (runway monitoring system) received a low risk of airport network and information systems (NIS) security with ratings of 0.2623 and 0.2915, respectively. An airport NIS risk assessment was aggregated (0.2288), indicating a low degree of security risk to the airport's network and information systems. The aggregated risk assessment of airport NIS, including financial loss data, was calculated as 0.1438, representing a low degree of security risk to the airport's network and information systems. Scenarios for evaluating airport assets are changing for students during education. The results of the developed model and its software will be part of the Simulation Center of the Faculty of Aeronautics. © 2020 by the authors

IMPLEMENTATION OF THE ABC MODEL IN A COMPANY DEALING WITH EXTRACTION OF RAW MATERIALS

ABC method is a new system for accurate product pricing, cost analysis of the causes of individual products and their optimization. The prices of products are accurately taken into account according to all relevant overhead costs in their actual context and relationships. Except of product costs, ABC method follows costs regarding customers, suppliers, distribution, transport, manufacturing, operational and security processes, management processes and other business activities. ABC method sees the company as a complex of interrelated activities and processes. ABC method represents more precise cost calculation for the product. The aim of the present article is to highlight the introduction of the ABC method to the enterprise and compare it with the traditional method. The result is to reduce costs by introducing ABC method to the enterprise
