Sorting for Sustainability: Harnessing Female Awareness of Zero Waste

J. P. Koltai Tamás Vinkóczi Éva Heimné Rácz

Publication Name: Journal of Sustainability Research

Publication Date: 2024-12-01

Volume: 6

Issue: 4

Page Range: Unknown

Description:

Background: Sustainable Development Goal 12 focuses on sustainable consumption and production patterns. Females are more likely to adopt these sustainable consumption practices due to their environmental attitudes. The scope of the present research is to develop a Hungarian model that can provide a theoretical explanation for the formation, viability and empowerment of zero waste awareness among females as they are sensitive to the issue and may have sufficient knowledge about it. Methods: An online questionnaire was distributed in a university environment in Hungary, resulting in 160 responses after data cleaning. The model was constructed using Partial Least Squares Structural Equation Modelling (PLS-SEM). Results: The results show that for females, the factors waste sorting and zero waste practicality account for 72.4% of the variance in zero waste awareness. The Beta values indicate that both effects are positive with the effect of the first (βZWS-ZWA = 0.523) being stronger than the second (βZWP-ZWA = 0.389). In addition, it can be concluded that women’s attitudes toward waste sorting have a strong positive impact (R2 = 0.542, βZWS-ZWP = 0.736) on zero waste practicality. Conclusions: The zero waste attitudes of female university students’ behavior are significantly related to the selective collection of waste and the practical use of old products. In addition, waste separation is a practical approach to environmental responsibility, as there is no need to dispose of all end-of-life products if they can be recycled. The model could help the government understand the factors and the mindset from a female perspective in order to partially support the decision-making process related to sustainability.

Consumer impulse buying in Hungary: A CB-SEM analysis of Hungarian consumer behaviour towards mobile short video applications based on a Chinese reference model

J. P. Koltai Tamás Vinkóczi Izabella Mária Végvári Martina Németh

Publication Name: Computers in Human Behavior Reports

Publication Date: 2024-12-01

Volume: 16

Issue: Unknown

Page Range: Unknown

Description:

Mobile Short Video Applications are becoming increasingly popular worldwide. The appropriate content can shape, improve or change consumers' purchasing decisions. This paper examines the attitudinal differences in impulse buying related to the use and acceptance of MSAs by adapting a model already validated in China to Hungarian users. The analysis was conducted using Covariance-Based Structural Equation Modelling (CB-SEM). A structured questionnaire survey of 283 respondents in Hungary shows that the Chinese model cannot fully be applied to Hungary. A major difference between the results of the two models is that in the Hungarian model, perceived expertise shows a positive relationship with flow experience. This indicates that video makers - in the case of Hungarian videos - should produce content including introductory information and the operation of the product. The results suggest that in the case of MSA use in Hungary, perceived expertise affects impulse buying indirectly, but flow experience directly. Flow experience is only influenced by perceived expertise (β = 0.31, ρ < 0.05), with an explained variance of 10%. Flow experience (β = 0.46, ρ < 0.05) with its direct effect on impulse buying behaviour accounts for 21% of the variance. Hungarian and Chinese MSA users have different preferences in terms of content, thus the results provide important information for both international short video creators and companies entering the international market.

Exploratory analysis of zero waste theory to examine consumer perceptions of sustainability: A covariance-based structural equation modeling (CB-SEM)

J. P. Koltai Tamás Vinkóczi Éva Heimné Rácz

Publication Name: Cleaner Waste Systems

Publication Date: 2024-08-01

Volume: 8

Issue: Unknown

Page Range: Unknown

Description:

Introduction: The analysis of corporate and consumer sustainability practices is currently the focus of several scientific disciplines due to their environmental impact and diversity. Objective: This research aims to create a hierarchy of consumer perceptions of zero waste thinking that can guide government decisions regarding university communities' sustainability efforts. To achieve the objectives of this study, Hungarian university citizens (students, faculty, staff) as potential zero waste consumers in Győr were involved in a purposive sampling approach. Methods: This study adopted the Covariance-Based Structural Equation Modeling (CB-SEM) methodology to prove the hypotheses related to the 7Rs regarding Zero Waste perceptions of university citizens. The rethink element of the hierarchy was defined as the default condition for the 7 R application and therefore remained at the top of the hierarchy as an endogenous variable. Results: The study concluded that it is possible to adapt a business 7 R framework for consumer use, but only 5Rs can be applied. The analysis was conducted at a 90% confidence level, under which condition the independent variables together explain 87% of the variance of the rethink factor. The results show that the four constructs, namely rot (β =0.12, ρ<0.1), reduce (β =0.21, ρ<0.1), recycle (β =0.26, ρ<0.05), and reuse (β =0.43, ρ<0.05) significantly affect rethinking. Based on these regression weights, a hierarchy of importance can be established. In line with the original 7 R business concept, rethink is at the top of the hierarchy, followed by the other elements. Conclusions: The results suggest that the zero waste attitudes of university citizens are currently limited to the 5Rs, which should require government leadership to strengthen these factors or a more consistent presence and support for the 2Rs that are missing from the established model. Governments can use the results of this research in their sustainability-related decisions.

Sentinels of Sustainability: Practices of Agricultural Farms Clustered in Hungary’s Farmers’ Markets

Károly Kacz J. P. Koltai Szabolcs Troján Tamás Vinkóczi Anita Miklósné Varga

Publication Name: Chemical Engineering Transactions

Publication Date: 2024-01-01

Volume: 114

Issue: Unknown

Page Range: 973-978

Description:

The analysis of local farmers' markets (FMs) is an important part of sustainability issues, as the products they offer can guarantee both the proper functioning of local farms and healthy nutrition for inhabitants. The aim of this research is to identify the most important characteristics of FMs small-scale businesses related to agricultural activities based on a convenience sample in Hungary. The database obtained by the questionnaire survey was compiled based on the answers of a total of 220 farm owners/managers. The results were subjected to analysis using a K-means clustering method, which identified four distinct groups of farms with the highest weighting of turnover from agricultural activity. The clustering distinguished beekeeping, arable crop production, animal husbandry, and vegetable and fruit production, which were treated as a separate cluster. The observed differences between the groups indicate that farms primarily engaged in beekeeping and livestock farming have the highest turnover. These findings may be manifested by the group’s member farms in terms of higher professional representation and high-quality products. A noteworthy distribution-related finding is that livestock products exhibit the greatest average distance from the point of origin to the FM, which can be attributed to the sparse geographical location of the production sites. The results could have a considerable consequence for policymakers in informing them about the design of support opportunities and the identification of beneficiary groups.

Factors and Variables Shaping Generation Z’s Adoption of FinTech

Tamás Vinkóczi Borbála Tamás Attila Kurucz Ewelina Idziak

Publication Name: Alternative Finance A Framework for Innovative and Sustainable Business Models

Publication Date: 2024-01-01

Volume: Unknown

Issue: Unknown

Page Range: 75-89

Description:

The digital age continues to redefine conventional financial paradigms, and Generation Z is at the forefront, navigating and influencing the trajectory of financial technology (FinTech) applications through their distinct attitudes, behaviors, and expectations. Gen Z is the new archetype and the new behavioral model. The behavioral intention to use FinTech services among Gen Z, explained by the inclusion of factors and in this way being an extension of financial theory, is the hot topic as this is still the beginning of learning the: Facilitating Conditions Intention (FCI), Attitude (A), Behavioral Intention (BI) that define the choices made by Gen Z. In a broader perspective, it is important to point out the main trends among Gen Z toward FinTech services and the conclusions of current research on them. These aspects make it particularly relevant to study the use of FinTech services, which can be done very effectively with social science analysis through structural models. The research presented in this chapter is both descriptive and exploratory, as it presents a theoretical framework that builds on previous research and includes contemporary perspectives based on new research findings.

Tech titans: Generation Z’s role in the FinTech evolution

Tamás Vinkóczi Borbála Tamás Attila Kurucz Ewelina Idziak

Publication Name: Journal of Infrastructure Policy and Development

Publication Date: 2024-01-01

Volume: 8

Issue: 10

Page Range: Unknown

Description:

The accessibility of FinTech services is increasing, and their convenience is making them more popular than traditional banks, particularly among Generation Z. The objective of this research is to identify and compare the factors influencing the conscious use of FinTech services among Generation Z members, who are the most active participants in this field of financial technology. The questionnaire based purposive sample consisted of Generation Z students who demonstrated adequate financial literacy and utilized FinTech, and who were learning in a university environment in Hungary and Romania. A sample of 600 respondents was selected for analysis after cleaning the data online. The methodological approach entailed the utilization of covariance-based structural equation modeling (CB-SEM). The results indicate that social influence (β = 0.18), consumer attitude (β = 0.53) and facilitating conditions intention (β = 0.11) all have a significant effect on the behavior intention, explaining 49% of the variance. In the context of performance expectation, the effect of facilitating conditions intention is not significant (p = 0.491). The motivation of Generation Z towards fintech solutions is evident in their preference for speed and ease of use. However, in order to reinforce consumer expectations and transfer the necessary experience and attitudes, it may be beneficial for service providers to adopt a partially different strategy in different countries. Generation Z can thus serve as a crucial reference point for the even more discerning expectations of subsequent generations. The findings may inform the formulation of strategies for fintech service providers to better understand customer behavior.

Consumer Perception of the Zero-Waste Concept: a Hungarian Case Study

J. P. Koltai Tamás Vinkóczi Éva Heimné Rácz

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 355-360

Description:

Sustainability is a concept that many people are familiar with, but it also seems elusive and difficult to generalize. Part of this concept is the Zero Waste mindset, which exists in equally diverse forms in people's minds. The research uses the 7R approach of the Zero Waste framework, adapted to consumers, to analyze which consumer groups can be distinguished from each other in terms of Zero Waste thinking. The methodology is based on a questionnaire analysis with the use of an HSD test. The results show that rethinking is the most widespread within the 7R concept, as the effects of most moderating variables (generation, gender, information gathering, product purchase, knowledge of the 7R concept, perceived income) can be measured in its case. In addition, 3 groups (Perfectionists, Adopters, and Rejecters) were created based on the consumers’ mindset of Zero Waste and named according to the means of the variables associated with the 7Rs. The present research is a Hungarian case study, which illustrates the existence of Zero Waste awareness and activities and should be extended to other nations as well.

The Sustainable Contribution of Artificial Intelligence to Higher Education - Results of a Pilot Study

J. P. Koltai Nikolett Gyurián Nagy Eszter Szabó-Szentgróti Gábor Szábo-Szentgróti Tamás Vinkóczi Nikolett Gyurián Nagy

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 487-492

Description:

The past year has seen revolutionary breakthroughs in the development of artificial intelligence-based (AI) products that can impact almost every aspect of life. The change raises the question of the sustainability of education and how technology will transform the way we currently teach. This study aims to develop a model and its hypothetical adaptation that can be used to analyse the adoption and use of artificial intelligence in university settings. The importance of AI in education can be captured in its ability to personalise learning pathways, improve teaching methods and automate related administrative tasks. AI technologies are able to adapt to the needs of individual learners, providing personalised instruction and improving learning outcomes. AI can also help educators by automating routine tasks, allowing them to focus on individualised instruction and create a more engaging and effective learning environment. Based on the accepted results of exploratory factor analysis as the applied method of this paper, the research concludes that the model adaptation is feasible, but it is worth considering changing the variable reflecting implementation to one that is accepted by educators as the concrete institutional implementation of AI is still a very distant scenario in higher education. Future research should incorporate these findings into the design of possible structural models, as this area of AI research has the potential to bring significant social science and educational benefits.

The generational division of online entertainment: The pleasure factors and manipulative effects of video streaming platforms

J. P. Koltai Tamás Vinkóczi Miklós Petra Majczán Lili Anna

Publication Name: Statisztikai Szemle

Publication Date: 2023-01-01

Volume: 101

Issue: 8

Page Range: 715-738

Description:

Rise of video streaming services has not only increased the popularity of available platforms, but has also changed the content consumption habits of households, pushing aside the opportunities provided by traditional television. Among subscribers and users representing generations tied to digitalization highly diversified views can exist regarding the selection of video-sharing platforms and their impact on users' traditional lifestyles. A structural equation model (CB–SEM) was applied to test our theory related to different generations' relationship to digitalization. Based on the results, the generational classification of users only affects the significance of the platform selection criteria, while the manipulative effect of the service is independent of this. The analysis reveals the importance of further research in this area, as the factors that are important for enjoyment may differ among generations.

Opportunities for analysing digitalisation in the context of banking services in the European Union, 2017–2018

Tamás Vinkóczi Gábor Kovács

Publication Name: Teruleti Statisztika

Publication Date: 2022-01-01

Volume: 62

Issue: 1

Page Range: 35-58

Description:

Nowadays, the development of the digital economy is gaining ground, changing consumer expectations through the opportunities offered by the internet and ICT, and requiring continuous improvements from financial service providers. The aim of this paper is to examine the regional dimension of banking services analyses by comparing the financial digital modernisation clusters and rankings of EU Member States with the traditionally accepted overall digital development analyses. After describing the impact of digitalisation on financial geography, the paper presents the European Union's (EU) digital transformation efforts and the financial relevance of digitalisation, as well as the major past changes and the current situation of the financial intermediation system. The findings of the empirical analysis show that the clustering of the EU28 Member States based on their overall digital development shows a partial correspondence with the results of studies focusing on digital banking services. The research confirms the advantages of the Northern European countries in digitalisation, but also reveals the divergent nature of the Western and Eastern Member States.
