Opis: Background and Purpose: The study investigated the impact of intergenerational differences on knowledge transfer among engineers in large Slovenian production organizations. Method: Using the Delphi method, experts answered open-ended questions. The process concluded with a consensus reached in the third round. The resulting questionnaire was then administered to engineers of all ages working in large production organizations. Results: The experts’ responses indicated that intergenerational differences are most prominent in the workplace in terms of computer literacy and the use of information and communications technology. Effective employee engagement, including exemplary leadership, a system of mentoring and reverse mentoring, and a supportive organizational culture, was found to enhance the flow of knowledge transfer. Statistical analysis revealed that there are statistically significance intergenerational differences in knowledge transfer among engineers in large production organizations (p < 0.001). Conclusion: The study’s findings suggest that recognizing intergenerational differences and fostering the abilities of employees can contribute to organizational success. However, the study is limited to engineers in large production organizations in Slovenia. Future research should explore organizations in a wider geographical area and across different sectors.

Opis: Emergency remote teaching presented many new and unknown situations. Many studies have examined the impact of distance education on children’s learning outcomes, including in the area of first language, particularly in reading and writing skills, and reading literacy. This research examines the area of literature teaching, more specifically the effects of the change in teaching on younger students’ reception ability. One hundred and ninety-six teachers participated in the quantitative, explorative study. Responses indicate that there are moderate and major differences in the receptive skills of elementary students in the first through third grades, compared to students taught prior to the pandemic.

Opis: In addressing the nuanced interplay between consumer attitudes and Artificial Intelligence (AI) use readiness in physical retail stores, the main objective of this study is to test the impacts of prior experience, as well as perceived risks with AI technologies, self-assessment of consumers’ ability to manage AI technologies, and the moderator role of gender in this relationship. Using a quantitative cross-sectional survey, data from 243 consumers familiar with AI technologies were analyzed using structural equation modeling (SEM) methods to explore these dynamics in the context of physical retail stores. Additionally, the moderating impacts were tested after the invariance analysis across both gender groups. Key findings indicate that positive prior experience with AI technologies positively influences AI use readiness in physical retail stores, while perceived risks with AI technologies serve as a deterrent. Gender differences significantly moderate these effects, with perceived risks with AI technologies more negatively impacting women’s AI use readiness and self-assessment of the ability to manage AI technologies showing a stronger positive impact on men’s AI use readiness. The study concludes that retailers must consider these gender-specific perceptions and attitudes toward AI to develop more effective strategies for technology integration. Our research also highlights the need to address gender-specific barriers and biases when adopting AI technology.

Opis: Discrete systems can offer advantages over continuous ones in certain contexts, particularly in terms of simplicity and reduced computational costs, though this may vary depending on the specific application and requirements. Recently, there has been growing interest in using fractional differences to enhance discrete models' flexibility and incorporate memory effects. This paper examines the dynamics of the discrete memristive Hindmarsh-Rose model by integrating fractional-order differences. Our results highlight the complex dynamics of the fractional-order model, revealing that chaotic firing depends on both the fractional-order and magnetic strength. Notably, certain magnetic strengths induce a transition from periodic firing in the integer-order model to chaotic behavior in the fractional-order model. Additionally, we explore the dynamics of two coupled discrete systems, finding that electrical coupling leads to the synchronization of chaotic dynamics, while chemical coupling ultimately results in a quiescent state.

Opis: The compatibility of seal materials with the working fluid is crucial for the flawless, energysaving, environmentally sustainable, and safe operation of any technical system. This is especially true for hydraulic systems operating under high operating pressure. The problem of materials compatibility comes into play when either a new type of seal material or a new type of fluid comes into use. The paper discusses the research findings regarding material compatibility testing of new high-tech ionic hydraulic fluids with commonly used seal materials. Due to the completely different chemical composition of these new fluids compared to the classical mineral-based oil, for these fluids, there are no standardized testing procedures. In these cases, we can only lean on the Standards that apply to classical fluids, which can lead to incorrect results. In the forefront of the paper is the discrepancy between the results obtained by the standardized test, and the test under real operating conditions. FKM, an excellent material for seals, proved to be the most suitable in the case of using ionic hydraulic fluid, according to a standardized test. However, it failed in the comparison test under real operating conditions, as the cylinder leaked. NBR seals proved to be a better solution.
