- Blockchain technology enhances sustainable higher educationPublication . Bucea-Manea-Țoniş, Rocsana; Martins, Oliva M.D.; Bucea-Manea-Țoniş, Radu; Gheorghiță, Cătălin; Kuleto, Valentin; Ilić, Milena P.; Simion, VioletaThis research investigates blockchain technology, focusing on the influence of motivation on collaborative work, which positively influences learning performance in Higher Education Institutions (HEI). In addition, blockchain technology is correlated with decentralisation, security and integrity, and anonymity and encryption. It can also be perceived as a consensus mechanism, rewarding students, professors, and universities as a smart contract. Therefore, this technology has been used to improve higher education. It also allows less informed people to interact with better-informed peers and mentors. Finally, this study aims to enhance the current state of blockchain applications comprehension. The methodology used for this research includes document analysis, literature review, content analysis (blockchain platforms), the case study method, and the survey method. In statistical considerations, aiming to evaluate indicators, this research presents the Composite Reliability Analysis, Cronbach Alpha Coefficients, and the Bootstrapping method (Variance Inflation Factor). All these analyses aimed to present a designed research model. This exploratory research gathered data from 150 students at 3 universities in Serbia, Romania, and Portugal. As demonstrated, using student motivation has a significant and positive impact on the quality of student collaborative work. Student collaborative work also correlates with students’ higher level of engagement in the educational process, and the more engaged students are, the better their learning outcomes will be. As a result, in higher education, student involvement boosted learning outcomes. Researchers found that motivation, teamwork, and student involvement were important factors in improving student learning outcomes, as were blockchain-based tools. The results from the quantitative analysis indicate that Collaborative work, Motivation, Engagement, MOOCs, AR, VR, Gamification, and Online class were associated with learning performance.
- Green and sustainable public procurement—an instrument for nudging consumer behavior. A case study on romanian green public agriculture across different sectors of activityPublication . Bucea-Manea-Țoniş, Rocsana; Martins, Oliva M.D.; Ilic, Dragan; Belous, Mădălina; Bucea-Manea-Țoniş, Radu; Braicu, Cezar; Simion, VioletaGreen Public Procurement (GPP) became an efficient instrument to achieve the objectives of environmental policy expressed by the European Commission in its Communications. At the same time, it must be addressed by the public authorities as a complex process, in which all purchased goods and services must integrate perfectly into an entire puzzle-like system of legislation, the construction field, innovation, healthcare, food, and education. Scientific references published in the Web of Science (WoS) mainly between 2017 and 2020 were investigated, and they analyze the implications of green public procurement in various fields, as presented by scientific communities. This article brings as a novelty in this context the identification of some barriers in the adoption of these processes, so that they can be overcome. Based on good practices and international standards and trends, the article shows how aspects related to the implementation of green procurement in society can be taken into account. In the second stage, we added a case study on Romanian green agriculture and discussions regarding inter-correlation between different fields and GPP.
- Insect-based food: a (free) choicePublication . Martins, Oliva M.D.; Bucea-Manea-Țoniş, Rocsana; Bašić, Jasmina; Coelho, Ana Sofia; Simion, VioletaThe literature highlights the importance of insect consumption for nutritional health habits. The increasingly clear legislation, the developed studies demonstrating their nutritional value, and the prospect of overcoming some barriers that have prevented consumers from consuming insects are among the reasons supporting the advantages of consuming insects. The leading determinants of consumption are culture and individual and social beliefs, accessibility to a particular nutritional resource, and individual behavior. The barriers to neophobia were analyzed by evaluating factors of influence and their respective relationship and meaning through quantitative research to measure the significance of the results. To develop a conceptual model that aims to change eating behavior and recognize structural aspects that can be barriers in the process of changing eating behavior, a methodological framework was developed. The methodological framework aimed to identify the characteristics that can be associated with the profile of opinion leaders, and it included a questionnaire which was applied to 213 young people. Moreover, the structural equation model was the statistical technique used. Given the projected population growth and increasing life expectancy, nutrition is a challenge in terms of health, but also in economic, social, and environmental respects. Aiming for sustainability, it is crucial to identify nutritional alternatives within the circular economy.
- Nudging consumer behavior with social marketing in Portugal: can perception have an Influence over trying insect-based food?Publication . Bucea-Manea-Țoniş, Rocsana; Martins, Oliva M.D.; Urdeș, Laura; Coelho, Ana Sofia; Simion, Violeta-ElenaSimple Summary The world population has been continuously growing, along with life expectancy. More people living longer results in greater demand for different resources, such as water and energy, but also for food. It becomes imperative to ensure basic needs, including food of good quality. In this sense, providing food for all increases the demand for human and animal protein. Considering that food production, namely animal protein, has been associated with negative impacts on the environment, it becomes crucial to identify more environmentally friendly alternatives to the growing demand for protein. Insect-based feeding is one of these alternatives. However, not all countries have accepted it. Neophobia and disgust are two major barriers. To overcome these barriers, we need to change behaviors. Social marketing campaigns can help. Abstract Social marketing campaigns are widely used to inform, educate, communicate, and promote healthy behaviors that add benefits to the individual, but also to society and the environment. Considering the low cost and high quality of insect-based food, this research aims to identify the main factors which can be used by social marketing campaigns to help people to try new foods, such as insect-based food. Although it is considered an important alternative to protein, there are a few countries that have not experienced it. In many Western countries, insect-based food is perceived as being disgusting. Neophobia is also a barrier to trying these foods. The main goal is to analyze if social marketing campaigns might influence perception (familiarity, preparation, visual, and information). Our model proves this assumption because we obtained high path coefficients, indicating that perception influences social beliefs, individual beliefs, and consumption intention. Thus, they will increase the consumption intention.
- Sensory perception nudge: insect-based food consumer behaviorPublication . Martins, Oliva M.D.; Bucea-Manea-Țoniş, Rocsana; Coelho, Ana Sofia; Simion, VioletaThe negative impact that animal protein sources have on the environment is a critical world problem. Finding new acceptable alternatives is crucial. Nevertheless, numerous factors influence the decision to try an unknown food. By adopting a consumer behavior perspective as well as approaching the possibility of overcoming neophobia, this research examined the influence of sensory perception on consumer behavior with regard to the experimentation with new foods, focusing on entomophagy. A theoretical model was developed, and path analysis and factor influence were based on the structural equation model (PLS-SEM), designed in SmartPLS, to test the model relationships. Despite the low level of awareness concerning the benefits of entomophagy, this study considered that many aspects influence experimentation with new food, specifically our sensorial system. Sensory perception is founded on the senses, such as the tactile, olfactory, visual, and gustatory senses, which can influence perception. In line with these assumptions, this research identified the three most important and decisive factors that can influence individuals’ sensory perceptions: preparation, visual and related aspects, and the presentation of the shape of food have an influence on sensory perception regarding entomophagy consumer behavior. People like to know the method of preparation as well as the ingredients and the color of the food. These findings are crucial to food business practitioners, policymakers, and marketers, who can adopt some food process strategies following sensory perception, that will contribute to changing the habits of consumers.
- The potential of blockchain technology in higher education as perceived by students in Serbia, Romania, and PortugalPublication . Kuleto, Valentin; Bucea-Manea-Țoniş, Rocsana; Bucea-Manea-Țoniş, Radu; Ilić, Milena P.; Martins, Oliva M.D.; Ranković, Marko; Coelho, Ana SofiaLifelong learning approaches that include digital, transversal, and practical skills (i.e., critical thinking, communication, collaboration, information literacy, analytical, metacognitive, reflection, and other research skills) are required in order to be equitable and inclusive and stimulate personal development. Realtime interaction between teachers and students and the ability for students to choose courses from curricula are guaranteed by decentralized online learning. Moreover, through blockchain, it is possible to acquire skills regarding the structure and content while also implementing learning tools. Additionally, documentation validation should be equally crucial to speeding up the process and reducing costs and paperwork. Finally, blockchains are open and inclusive processes that include people and cultures from all walks of life. Learning in Higher Education Institutions (HEI) is facilitated by new technologies, connecting blockchain to sustainability, which helps understand the relationship between technologies and sustainability. Besides serving as a secure transaction system, blockchain technology can help decentralize, provide security and integrity, and offer anonymity and encryption, therefore, promoting a transaction rate increase. This study investigates an alternative in which HEI includes a blockchain network to provide the best sustainable education system. Students’ opinions were analyzed, and they considered that blockchain technology had a very positive influence on learning performance.
