Opis: Background and Purpose: E-commerce has reshaped consumer behaviour by offering unparalleled convenience, variety and accessibility, while creating new opportunities for businesses to grow revenues. Despite its prominence, there remains a need for parsimonious models that explain online purchase intention in terms of core consumer perceptions. This study aims to develop and test a structural equation model (SEM) in which consumer perceived benefits and attitudes toward the web drive intention to purchase online. Methods: An online survey was administered to 190 Slovenian consumers. Questionnaire items were drawn from established scales measuring (a) perceived benefits of online shopping, (b) attitude toward the web, and (c) online purchase intention. Internal consistency was assessed via Cronbach’s alpha. SEM was then applied using IBM SPSS AMOS to evaluate both measurement and structural components of the model, testing hypotheses that perceived benefits influence both attitude and intention, and that attitude further mediates intention. Results: The survey instrument demonstrated excellent reliability (Cronbach’s α = 0.92). The three-construct SEM explained 74 % of the variance in online purchase intention. Fit indices indicated very good model performance (NFI = 0.969, NNFI = 0.970, CFI = 0.979, IFI = 0.979). All hypothesized paths were significant, confirming that higher perceived benefits enhance both positive web attitudes and purchase intentions, and that web attitudes further bolster intention. Conclusion: This streamlined SEM offers a robust and well-fitting explanation of consumer online purchase intentions. E-commerce platforms can leverage these insights by emphasizing the specific benefits consumers value and cultivating positive web experiences to drive sales. The model offers both practical guidance for online retailers and a foundation for future research, such as incorporating environmental consciousness, to refine our understanding of sustainable e-commerce adoption.

Opis: In this master’s thesis, we researched how people perceive artificial intelligence (AI) and the factors that shape their attitudes. Understanding public attitudes toward AI is crucial for ensuring its responsible development and deployment, aligning technological progress with societal expectations, and addressing ethical and social concerns. The primary goal of this study was to gain a comprehensive understanding of how the public forms attitudes toward AI and how these are influenced by perceived threats, societal benefits, and trust in institutions involved in AI development. The theoretical part reviewed the literature on the foundations of attitudes and on public perceptions of artificial intelligence, providing an essential framework for the empirical analysis. In the empirical part, a survey was conducted to explore public attitudes toward AI. Respondents were asked about their perceptions of AI as a potential threat, its societal benefits, their level of trust in institutions and companies responsible for AI, and their overall stance toward the technology. The results revealed that individuals who perceive AI as a threat to their jobs or privacy tend to hold significantly more negative attitudes. In contrast, perceived societal benefits and institutional trust did not show a statistically significant impact on overall attitudes toward AI. These findings highlight that personal concerns play a greater role than broader societal considerations or institutional trust. They also underline the importance of addressing individual fears and enhancing transparency in the development and deployment of AI technologies. Although the study faces limitations, such as a non-representative sample and reliance on self-reported survey data, it provides important insights into the complexity of public attitudes toward AI. Future research should include longitudinal and cross-cultural studies, as well as a combination of quantitative and qualitative methods, to capture the dynamic and multifaceted nature of public perceptions. The study contributes to a deeper understanding of how AI is perceived and emphasizes the need for a responsible, ethical, and socially sensitive approach to its integration into society.

Opis: Background/Purpose This article explores consumers’ perception of the benefits of intelligent service robots (ISR) in the purchasing process, their trust in artificial intelligence (AI), their perception of AI-related threats, and the impact of these variables on consumer attitudes toward AI. Additionally, the study examines the moderating effect of perceived AI-related threats on the relationship between perceived benefits and trust on one side and the formation of consumer attitudes toward AI on the other. Methods The research was conducted in the first half of 2024 on a judgmental sample of 224 employed consumers in the Republic of Slovenia. Data were collected through a structured online questionnaire. For the empirical analysis, a non-parametric approach using SEM-PLS modelling was applied to examine relationships between the studied research constructs. Results The findings indicate that perceived benefits of ISR have a strong and positive impact on consumer attitudes toward AI, while perceived AI-related threats strongly and negatively influence these attitudes. Moreover, the results reveal that perceived AI-related threats significantly and negatively moderate the effect of consumers’ perceived trust in AI on the formation of their attitudes toward AI. Conclusion The results of this study contribute significantly to the theoretical understanding of employed consumers’ attitudes toward AI. They also provide practical implications for companies in developing predictive models of consumer behaviour and defining effective marketing strategies to encourage AI adoption in the purchasing process.

Opis: Background: Fermented foods are staples of the human diet and fermentation process has been used by humans for thousands of years. The preparation of fermented foods was performed in the past without knowledge of the role of microorganisms involved. Nowadays, fermented foods, due to their proclaimed health benefits for consumers, are becoming increasingly popular. Our study was constructed to provide data on awareness and use of fermented foods among people in North-eastern Slovenia. Methods: The cross-sectional study included 349 individuals (16–89 years of age). An online survey was designed to assess the participants' knowledge of fermentation, fermented foods, the consumption of fermented foods and awareness of the health benefits. Data were collected from March to June 2021 and analyzed using IBM SPSS 27.0. Results: Compared with the youngest participants (< 21 years) knowledge of fermentation was higher in older individuals (p < 0.001). More than a half of the participants recognized the role of lactic acid bacteria and yeasts in fermentation process, however, only 18.3% of participants were aware of the role of the molds. Only 25.9% of the participants have become acquainted with fermented foods at home and 62.2% of them were aware of health benefits of fermented foods, but mostly on gastrointestinal health and the immune system. Conclusions: As people today live predominantly in urban areas and incline towards westernized foods, they often lack the knowledge of fermentation and awareness regarding the nutritional value of fermented foods and their preparation. Steps should be taken to educate younger generations regarding the health benefits of fermented foods especially considering that most of them expressed their interest in learning more about the process.

Opis: Software organizations are always looking for approaches that help improve the quality and productivity of developed software products. Quality software is easy to maintain and reduces the cost of software development. The Software Factories (SF) approach is one of the approaches to provide such benefits. In this paper, the quality and productivity benefits of the SF approach were examined and evaluated with an experiment involving two treatments - the traditional and the SF approach. For the purposes of this experiment, the Goal – Question – Metric (GQM) approach was used. Participants were grouped into thirty two teams. There were sixteen projects available. The results were evaluated and presented through quality and productivity criteria, which were used for the experimental study. The results showed that the Software Factories approach was significantly better than the traditional approach.
